The present invention relates to a technology that is effective in recycling a useful substance contained in an electronic device.
An attempt to recover and reuse useful resources such as noble metals and rare metals from a waste electronic device is going on. From the viewpoint of national security, there is a big challenge to ensure a scare resource including rare metals.
For example, Patent Literatures 1 to 3 disclose technologies of recycling the electronic device. However, in the disclosed technologies, the useful resource is extracted for the purpose of the recycling by a physical or chemical treatment, after products are crushed or powdered or after a mixture is prepared. In the technologies, cost increases to recycle the useful resource, and it is difficult that a recovery cost of the useful resource is lower than a selling price of the extracted useful resource.
Patent Literatures 4 and 5 propose methods for detecting a position of the extraction object component to cut and extract the component from a product. In the method of Patent Literature 4, with respect to an HDD (Hard Disk Device) in which a structure is standardized, the component containing a scarce resource is selectively cut using structure information. In the method of Patent Literature 5, a transmission image of an object product is formed using an X-ray, a position of a motor is measured from the transmission image, a proper cutting position is decided, and the object product is cut to take out the motor. However, because of low versatility, it is difficult for the methods of Patent Literatures 4 and 5 to provide a proper treatment corresponding to a product type or a product specification to various products appearing on a market.

Unless prices of useful resources taken out from electronic devices such as a mobile phone and a computer are higher than the recovery cost, a recycling business cannot be established. In order to reduce the recovery cost, it is necessary to understand a kind or a content of the useful resource contained in the electronic device or a component mounting board and where the useful resource is contained in the electronic device or component mounting board before a recovery process. When the pieces of information are previously obtained, the electronic device or the component mounting board can be cut and sorted, the recovery process can be decided, or whether the electronic device or the component mounting board is sent to the recovery process or disposed (because it is too costly) can be determined, and therefore the recovery cost can be reduced as much as possible.
Because the electronic device is originally designed by CAD, the kind and position of the component mounted on the electronic device are easily understood using the design data. Therefore, the kind or content of the useful resource recyclable from the component can be recognized. However, a manufacturer rarely discloses design data because the design data of the electronic device includes many pieces of confidential information of the manufacturer. Resultantly, a system that detects the kind or content of the useful resource in the electronic device using the design data is lack in feasibility.
An object of the present invention is to provide a technology that is effective in recycling the specified substance by detecting the kind or content of the recyclable specified substance contained in the electronic device or the constituent component of the electronic device using a simple method.
According to a first aspect, in a data structure, characteristic data expressing a characteristic of a useful body used in object recognition with a computer and containing substance data expressing a kind and a content of a recyclable specified substance contained in the useful body are associated with each other in each kind of the useful body with respect to the useful body, the useful body being a constituent component of an electronic device and an electronic device, the electronic device and the electronic device containing the specified substance.
For example, when the used electronic device or the constituent component of the used electronic device is provided, the use of the library (also referred to as a “useful body library”) having the data structure of the first aspect can specify the kind of the electronic device or the constituent component of the electronic device by object recognition with a computer (that is, identify which one of the useful bodies the electronic device or the constituent component corresponds to). Additionally, how much the electronic device or the constituent component of the electronic device contains the recyclable specified substance can easily be determined based on a recognition result. Accordingly, the efficiency of the treatment to recover the specified substance from the electronic device or the constituent component of the electronic device can be achieved by information processing using the useful body library.
The constituent component of the electronic device means an article that can be separated or taken apart from the electronic device. For example, the component mounting board incorporated in the electronic device or the electronic component mounted on the component mounting board corresponds to the constituent component of the electronic device. Examples of the useful body library include a useful body library (also referred to as a “component library”) in which the characteristic data of the electronic component and the containing substance data are associated with each other in each kind of the electronic component, a useful body library (also referred to as a “board library”) in which the characteristic data of the component mounting board and the containing substance data of the board are associated with each other in each kind of the component mounting board, and a useful body library (also referred to as an “electronic device library”) in which the characteristic data of the electronic device and the containing substance data of electronic device are associated with each other in each kind of the electronic device. The containing substance data of the board may include data of the kind and content of the containing substance of individual component mounted on the board or data of a total content of the containing substances of all the components mounted on the board. The same holds true for the containing substance data of the electronic device. Plural kinds of libraries may be stored in a storage device, or the data of the electronic device, the data of the component mounting board, and the data of the electronic component may be mixed in the identical library.
According to a second aspect, in the data structure, the characteristic data includes image data of the useful body and/or data expressing the characteristic extracted from the image data of the useful body.
In the configuration of the second aspect, when the image data of the useful body or the data expressing the characteristic of the image is registered in the useful body library as the characteristic data, the data structure is easily applied to the image recognition processing in which the image of the electronic device or the constituent component of the electronic device is used.
According to a third aspect, in the data structure, the image data is X-ray image data.
In the configuration of the third aspect, when the X-ray image data and/or the data extracted from the X-ray image data is used, the component that is not visibly recognized from the appearance because of the location of the component inside the electronic device can be recognized, and the data structure can be applied to various objects.

For a user of the library provision system of the electronic device analysis device, because the useful body library can be used on line, a storage capacity on the electronic device analysis device side can be decreased, and the latest library can always be used (even if the user does not update the data of the useful body library).

According to a twenty-fourth aspect, the electronic device analysis device according to any one of the tenth to fourteenth and sixteenth to twentieth aspects further includes a specified substance extraction method decision unit configured to acquire extraction method definition data for the component mounting board based on the recognition result of the board recognizer from a specified substance information library having a data structure in which the extraction method definition data is associated in each kind of the component mounting board, a method for extracting the specified substance from the component mounting board being defined in extraction method definition data.
In the electronic device analysis device of the twenty-fourth aspect, the improvement of recovery work efficiency and the reduction of recovery cost can be expected by using the data in the subsequent recovery process.
Accordingly, in the present invention, the kind or content of the specified substance contained in the electronic device or component mounting board can be detected by the simple method, and the specified substance can efficiently be recovered.
(Configuration of Analysis Device)
A configuration of an electronic device analysis device according to a first embodiment of the present invention will be described with reference to
As illustrated in
In the first embodiment, an X-ray imaging unit that photographs a two-dimensional transmission X-ray image is used as the imaging unit 10. Specifically, the imaging unit 10 includes an X-ray generator 100 that irradiates the analysis object 13 with an X-ray, an X-ray detector 101 that detects the X-ray transmitted through the analysis object 13, and an image producer 102. In the first embodiment, using the line-sensor type X-ray detector 101 in which many detection elements are arrayed in a main scan direction, a transmission X-ray amount is continuously detected while the analysis object 13 is conveyed in a sub-scan direction by the conveying device 12, thereby acquiring a two-dimensional X-ray image. The image producer 102 has a function of performing preprocessing (such as correction of density or contrast, noise removal, trimming of a region of the analysis object 13, and rotation of the image) as needed in addition to the production of a two-dimensional image data. The functions of the image producer 102 may be provided in the information processor 11.
The imaging unit 10 is not limited to the configuration in
As illustrated in
The component library 110 is a database in which “component data” of information about an electronic component is stored. The pieces of component data of various electronic components are previously registered in the component library 110. The component library 110 may be stored in a local storage such as the auxiliary storage device, stored in a network storage such as a server and a cloud, or dispersed in a plurality of storages.
As illustrated in
The component recognizer 111 has the function of recognizing (specifying) the electronic component mounted on the board from the image data of the board of the analysis object 13 input from the imaging unit 10, and the containing substance decision unit 112 has the function of determining the kind or content of the specified substance contained in the analysis object 13 based on a recognition result of the component recognizer 111. The detained functions will be described below together with an operation flow of the analysis device 1.
(Operation of Analysis Device)
The imaging unit 10 photographs the X-ray image of the component mounting board incorporated in the electronic device of the analysis object 13, and the information processor 11 captures the image data of the component mounting board (Step S30).
Then, the component recognizer 111 detects a component region from the image 40 of the whole board (Step S31). Any detection algorithm, such as a method for detecting a region seemed to be the component by pattern matching and a method for extracting a region having equal density (pixel value) by binarization or clustering, may be used.
Component recognition processing is performed on each component region detected in Step S31. An algorithm for recognizing the component based on the characteristic of the solder is described by way of example. The component recognizer 111 selects the interesting component region to perform binarization processing (Step S32).
The component 41 in
The component recognizer 111 refers to the component library 110 to compare the solder characteristic of the component characteristic data for each registered component with the solder characteristic extracted from the component region of the X-ray image, and evaluates a similarity (consistency) of the solder characteristic to specify the component (Step S34). Because various techniques generally used in the image recognition can be used with respect to a similarity calculation equation or a similarity evaluation algorithm, the detailed description is omitted. In the case that the component region of the X-ray image is not similar to any registered component in the component library 110 (for example, the registered component in which the similarity exceeds a predetermined threshold does not exist), the following pieces of processing may be skipped with respect to the component region.
In the case that the component recognizer 111 successfully recognizes the component, the containing substance decision unit 112 reads the component ID and containing substance data of the component from the component library 110, and adds the component ID and the containing substance data to a containing substance list (Step S35). The containing substance list means data in which the kind and content of the (recoverable) specified substance contained in the electronic component mounted on the board are recorded.
After the pieces of processing in Steps S32 to S35 are repeatedly performed on all the components of the analysis objects 13, the containing substance decision unit 112 outputs the containing substance list to end the analysis processing (Step S36).
The produced data of the containing substance list is used in a post-process. For example, delivery of the component to the post-process or disposal of the component can be selected based on existence (or content) of the containing substance, or which recovery process the component is delivered to can be sorted based on the kind of the containing substance. Alternatively, only the necessary component can automatically be taken out from the electronic device or component mounting board by controlling a cutting machine based on the position information about the component containing the specified substance. For the large board having a relatively low degree of integration, efficiency of the recovery treatment can be expected to be largely improved by taking out only the valuable component through such methods.
In the analysis device of the first embodiment, the treatment to recover and recycle the specified substance can efficiently be performed because whether specified substances such as noble metals and rare metals are contained in the electronic device or the component mounting board can automatically be determined. The use of the X-ray image can recognize the components, such as the component existing in the electronic device, the component of a multilayer board, and the component mounted on the back side of the board, which are invisible from the appearance, and the analysis device of the first embodiment can be used in various objects. The characteristic of the solder constituting the clear image of the X-ray image is used in the component recognition, so that sufficient recognition accuracy can be obtained by the relatively easy processing.
In the first embodiment, the component is specified by evaluating the similarity of the solder characteristic. Alternatively, for example, preferably the similarity between the image of the registered component and the image of the component extracted from the analysis object is evaluated by calculating a correlation coefficient or a difference image between the images. In the case that the similarity between the images is evaluated, a processing speed may be enhanced by the use of the low-resolution image or the division of the image into small blocks.
While each component is recognized in the first embodiment, the board is set to a recognition object in a second embodiment. A configuration unique to the second embodiment will mainly be described below, and the description of the configuration common to the first embodiment is omitted.
As illustrated in
(Operation of Analysis Device)
The imaging unit 10 photographs the X-ray image of the component mounting board incorporated in the electronic device of the analysis object 13, and the information processor 60 captures the image data of the component mounting board (Step S70).
The board recognizer 601 extracts a board characteristic amount from the X-ray image of the analysis object (Step S71). As described above, the layout of the component, the shade or texture characteristic, the edge characteristic, the histogram, and the like can be used as the board characteristic amount.
The board recognizer 601 refers to the board library 600 to compare the board characteristic data for each registered component with the characteristic amount extracted from the X-ray image of the analysis object, and evaluates the similarity (consistency) of the characteristic amount to specify the board (Step S72). Because various techniques generally used in the image recognition can be used with respect to a similarity calculation equation or a similarity evaluation algorithm, the detailed description is omitted. In the case that the characteristic amount extracted from the X-ray image is not similar to any registered board in the board library 600 (for example, the registered board in which the similarity exceeds a predetermined threshold does not exist), namely, in the case that the characteristic amount is an unknown board, the following pieces of processing may be skipped.
In the second embodiment, the board is specified by evaluating the similarity of the characteristic amount. Alternatively, for example, preferably the similarity between the image of the registered board and the image of the analysis object is evaluated by calculating the correlation coefficient or difference image between the images. In the case that the similarity between the images is evaluated, a processing speed may be enhanced by the use of the low-resolution image or the division of the image into small blocks.
In the case that the board recognizer 601 successfully recognizes the board, the containing substance decision unit 602 reads the board ID and mounting component data of the board from the board library 600. The containing substance list in
In the analysis device of the second embodiment, similar to the first embodiment, the treatment to recover and recycle the specified substance can efficiently be performed because whether specified substances such as noble metals and rare metals are contained in the electronic device or the component mounting board can automatically be determined. The use of the X-ray image can recognize the components, such as the component existing in the electronic device, the component of a multilayer board, and the component mounted on the back side of the board, which are invisible from the appearance, and the analysis device of the first embodiment can be used in various objects. Additionally, the simplification and speed enhancement of the processing can be expected by adopting the board recognition method, and the accurate information about the position or containing substance of each component on the board can be acquired from the board library 600.
A third embodiment is a configuration in which a recognition rate is improved by a combination of the board recognition and the component recognition. The configuration unique to the third embodiment will mainly be described below, and the description of the configuration common to the first and second embodiments is omitted.
The imaging unit 10 photographs the X-ray image of the component mounting board incorporated in the electronic device of the analysis object, and the information processor 80 captures the image data of the component mounting board (Step S90). Then the board recognizer 801 extracts the board characteristic amount from the X-ray image of the analysis object (Step S91). The board recognizer 801 refers to the board library 800 to compare the board characteristic data for each registered component with the characteristic amount extracted from the X-ray image of the analysis object, and evaluates the similarity (consistency) of the characteristic amount to specify the board (Step S92). The pieces of processing in Steps S90 to S92 are identical to Steps S70 to S72 in
The board recognizer 801 branches the processing based on whether the board of the analysis object is successfully recognized (Step S93). As to whether the board is successfully recognized, for example, the determination that the board is successfully recognized is made when only one registered board having the similarity more than a predetermined threshold is detected, and the determination of the false recognition is made when the registered board having the similarity more than the predetermined threshold does not exist, or when a plurality of registered boards having comparable similarities exist (that is, when the boards are not narrowed down to one registered board).
When the determination of the false recognition is made (NO in Step S93), the board recognizer 801 selects some registered boards that are likely to be identical to the analysis object as candidate boards from the board library 800 (Step S94). For example, N candidate boards may be selected in the descending order of the similarity calculated in Step S92, or all the registered boards having the similarities more than a certain standard may be selected as the candidate boards. The board recognizer 801 produces a candidate board ID list in which the board ID of each selected candidate board is described, and transfers the candidate board ID list to component recognizer 803.
The component recognizer 803 performs the component recognition processing on the X-ray image of the component mounting board to specify each component mounted on the board of the analysis object (Step S95). Because the contents of the component recognition processing are similar to those in Steps S31 to S35 of the first embodiment in
In the case that the candidate boards can be narrowed down to one board in Step S96, or that the board is successfully recognized in Step S93, the containing substance decision unit 804 reads the board ID and mounting component data of the board from the board library 800. The containing substance list in
In the analysis device of the third embodiment, similarly to the first and second embodiments, the treatment to recover and recycle the specified substance can efficiently be performed because whether specified substances such as noble metals and rare metals are contained in the electronic device or the component mounting board can automatically be determined. The use of the X-ray image can recognize the components, such as the component existing in the electronic device, the component of a multilayer board, and the component mounted on the back side of the board, which are invisible from the appearance, and the analysis device of the first embodiment can be used in various objects. Additionally, the board recognition of the relatively light processing is initially performed, and the component recognition is auxiliarily performed in the case that it is difficult to perform the recognition in units of boards, so that the processing efficiency can be improved as a whole while the board recognition rate can be improved.
A fourth embodiment is a configuration in which the board is specified using the component recognition result. The configuration unique to the fourth embodiment will mainly be described below, and the description of the configuration common to the first to third embodiments is omitted.
The imaging unit 10 photographs the X-ray image of the component mounting board that is of the analysis object, and the information processor 1010 captures the image data of the component mounting board (Step S110). The component recognizer 1001 performs the component recognition processing on the X-ray image of the analysis object to specify each component mounted on the board of the analysis object (Step S111). Because the contents of the component recognition processing are similar to those in Steps S31 to S35 of the first embodiment in
The board recognizer 1003 refers to the board library 1002 to narrow down the board including the component group described in the component ID list from the registered boards (Step S113). When the plurality of registered boards including the component group described in the component ID list exist, the board recognizer 1003 may narrow down the plurality of registered boards to one board by comparing the pieces of image data or characteristic amounts of the board with each other. The specific method is already described in the second embodiment. In the case that the corresponding board is not found in the registered boards, namely, in the case that the analysis object is an unknown board, the following step is skipped.
In the case that the registered boards can be narrowed down to one board in Step S113, the containing substance decision unit 1004 reads the board ID and mounting component data of the board from the board library 1002. The containing substance list in
In the analysis device of the third embodiment, similarly to the first and second embodiments, the treatment to recover and recycle the specified substance can efficiently be performed because whether specified substances such as noble metals and rare metals are contained in the electronic device or the component mounting board can automatically be determined. The use of the X-ray image can recognize the components, such as the component existing in the electronic device, the component of a multilayer board, and the component mounted on the back side of the board, which are invisible from the appearance, and the analysis device of the first embodiment can be used in various objects. The board is specified based on the component recognition result, and the information about the containing substance or position of each component is acquired from the board library. Therefore, all the components are not necessarily recognized with high accuracy from the image of the analysis object, and the simplification and speed enhancement of the processing can be achieved. Additionally, the information about the containing substance or position of each component on the board can correctly be acquired.
The production of the component data, the registration of the component data in the component library, the production of the board data, and the registration of the board data in the board library will be described in a fifth embodiment.
The measurement unit 120 measures a registration object 126 (such as the electronic device and the component mounting board), and outputs measured data obtained from the registration object 126 to the information processor 121. In the fifth embodiment, the measurement unit 120 includes an X-ray imaging unit 120a that photographs a transmission X-ray image, a visible-light imaging unit 120b that photographs a visible-light image (appearance), and a shape measurement unit 120c that measures a three-dimensional shape of the board or component. Various devices such as a device that measures a surface shape using special pattern lighting and a device that measures the surface shape using a laser displacement meter can be used as the shape measurement unit 120c. Additionally, for example, an X-ray tomographic apparatus such as a tomosynthesis apparatus and a CT apparatus may be used as the measurement unit 120.
The information processor 121 has functions of an interactive board data register 122 and a component data register 123. Typically the information processor 121 can be constructed with a computer including a CPU (Central Processing Unit), a RAM (Random Access memory), an auxiliary storage device such as a magnetic disk and a semiconductor memory, an input device, a display device, and a communication interface. In this case, the CPU reads and executes a program stored in a storage device such as the auxiliary storage device, thereby implementing each function of the information processor 121. The configuration of the information processor 121 can be constructed with one computer, or implemented by a client-server scheme, grid computing, or cloud computing. Alternatively, all or a part of the functions of the information processor 121 can be implemented by a logic circuit such as an ASIC and an FPGA or an on-board computer. A board library 124 and a component library 125 in
(Registration Processing)
For example, in the case that a manufacturer releases a new electronic device, or that the analysis device makes the determination of an unknown board, the board data and the component data are newly registered using the library creation device.
As illustrated in
The interactive board data register 122 has a function of providing an environment in which the board data and the component data can interactively be input using a GUI (Graphical User Interface) to the user. For example, when the user selects the pieces of measured data captured from the measurement unit 120 to execute a new board command, the pieces of measured data are displayed on a display device, and the interactive board data register 122 allocates the board ID. Any numerical character or character string may be allocated as the board ID, or the manufacturer, the serial number, or the board number may be read from the visible-light image to produce the board ID. Alternatively, the user may input the board ID.
The user inputs the component data with respect to the transmission X-ray image or visible-light image that is displayed on the display device. For example, when the user designates the component region using an input device such as a mouse to execute a component registration command, a component data input window (not illustrated) is displayed to encourage the user to input the component ID and the containing substance data. The user inputs the component ID of the component and information about the kind and content of the specified substance contained in the component. At this point, the interactive board data register 122 searches the component library 125. In the case that the registered component (or the registered component similar to) identical to the component exists, the interactive board data register 122 may assist the user to input the component data of the component by providing the information about the component to the user, or automatically reflecting the information about the component to the component data.
The interactive board data register 122 extracts the component characteristic data of the component. Examples of the component characteristic data include the image data of the visible-light image of the component, the image data of the transmission X-ray of the component, various characteristic amounts (such as the size and shape of the component, the number, shape, size, and arrangement of the solder, the number, shape, size, and arrangement of the electrode, the characteristic of the shade or texture, the edge characteristic, and the histogram) extracted from the pieces of image data, the component position on the board, and a height and an attitude of the component obtained from the surface shape. The kind of the component characteristic data to be registered may properly be selected according to the function or use of the analysis device.
When the user executes a data registration command after the input of the component data is ended with respect to all the components on the board, the interactive board data register 122 produces the board characteristic data. Examples of the board characteristic data include the visible-light image data or transmission X-ray image data of the board and various characteristic amounts (such as the layout of the component, the characteristic of the shade or texture, the edge characteristic, and the histogram) extracted from the pieces of image data. The kind of the board characteristic data to be registered may properly be selected according to the function or use of the analysis device. The interactive board data register 122 additionally registers the acquired board data in the board library 124.
The component data register 123 has a function of registering the component data in the component library 125. The component data register 123 receives the component data, which is input to or acquired with the interactive board data register 122, to update the component library 125. At this point, in the case that the identical component data is already registered in the component library 125, the component data register 123 may improve reliabilities of the component characteristic data and containing substance data by adopting higher-reliability data from the new data and the existing data, or performing statistical processing (such as average) of the new data and the existing data. Therefore, the component recognition rate can be expected to be improved in the analysis device.
The registration of the unknown object 126 in the board data and component data libraries is completed. The user of the analysis device can use the registration processing of the fifth embodiment in a process of causing the analysis device to learn an unknown object, or a person (service provider) who sells and maintain the analysis device can produce data of a new product to provide the analysis device to the user. As to a way to provide the data of the new product, a recording medium may be distributed, downloaded through a network, or provided as a cloud service (the latest board library and component library are prepared in the online storage).
When receiving a library use request from one of electronic device analysis devices 184 connected to the data provision unit 182 through a network 183 such as the Internet, the data provision unit 182 transmits the data of the board library or component library stored in the storage 181 to the electronic device analysis device 184. That is, the data provision unit 182 has functions of the board recognizer, component recognizer, and containing substance decision unit of the electronic device analysis device in
In the mechanism in
In the case that the online library is usable, the library needs not to be stored in the local storage of the electronic device analysis device 184. Alternatively, while the library (also referred to as a “local library”) is stored in the local storage of the electronic device analysis device 184, the local library and the online library may properly be used. For example, the local library is referred to by default, and the online library may be referred to in the case that the corresponding component or board is not found in the local library. Alternatively, preferably the electronic device analysis device 184 automatically or manually acquires the latest data from the online library to update the local library.
A business model, where a person who produces the component data or the board data to register the pieces of data in the library provides the pieces of data to a third party by the cloud service for profit, may be constructed. This means formation of a sensing data market that sells sensing data obtained with the X-ray imaging apparatus to a consumer who uses an application system in which the sensing data is required through the Internet.
IoT (Internet of Things) is advocated as an infrastructure realizing an optimum society. From a macroscopic viewpoint, IoT forms a system that optimizes resources such as time, space, human, information, and energy by various grain sizes. The optimization means that resources are transferred from a low-necessity portion to a high-necessity portion or that resources can be used in a higher-value form. Because a “transaction” is made in transfer of a resource or setting of a right to use, a distribution function is required as the infrastructure of the transaction. It is necessary that IoT have a “sensing data distribution function” as one of the distribution functions.
The cloud service of the component data or board data corresponds to a sensing data distribution function in IoT. In other words, the mechanism that decides from which one of library providers the user purchases the sensing data using metadata including the kind of the interesting specified substance (resource) and the kind and value of the object component as a matching item for the data distribution can be constructed.
A sixth embodiment is a configuration in which a board analysis technique is properly selected based on a pre-sensing result.
(Configuration of Analysis Device)
A configuration of an analysis device according to a sixth embodiment will be described below with reference to
The analysis device includes a pre-sensing unit 130, an imaging unit 131, and an information processor 132. The information processor 132 has functions of aboard library 133, a board recognizer 134, a component library 135, a component recognizer 136, and a containing substance decision unit 137.
The pre-sensing unit 130 simply measures the analysis object 13 (such as the electronic device and the component mounting board) prior to the main measurement of the imaging unit 131. In the sixth embodiment, a CCD camera that photographs the visible-light image (appearance image) of the analysis object 13 is used as the pre-sensing unit 130. Sensing data (image data) obtained with the pre-sensing unit 130 is input to the information processor 132. The imaging unit 131 can take tomographic photographing of the analysis object 13. In the sixth embodiment, the X-ray imaging apparatus such as such as tomosynthesis and CT is used as the imaging unit 131. Although the X-ray tomographic photographing has a merit that detailed information about the electronic device or the multilayer board can be observed, the X-ray tomographic photographing has a demerit that it takes a long time for photographing and image reconfiguration processing. In the sixth embodiment, the necessity of the X-ray tomographic photographing is determined from a result of the pre-sensing that can simply be measured in a short time, whereby the efficiency of the processing is improved.
The pre-sensing unit 130 photographs the visible-light image (appearance image) of the analysis object 13, and the information processor 132 captures the image data of the analysis object 13 (Step S140). Then the board recognizer 134 extracts the board characteristic amount from the image data of the analysis object 13 (Step S141). Examples of the board characteristic amount include the size, color, and shape of the board, the layout of the component, the characteristic of the shade or texture, and the edge characteristic. The board recognizer 134 refers to the board library 133 to compare the board characteristic data for each registered component with the characteristic amount extracted from the image data of the analysis object 13, and evaluates the similarity (consistency) of the characteristic amount to specify the board (Step S142).
When the board is successfully recognized using the appearance image (YES in Step S143), because the information about the component mounted on the board or the containing substance can be acquired from the board library 133, the X-ray tomographic photographing and the component recognition are skipped. That is, the containing substance decision unit 137 reads the mounting component data of the board from the board library 133, produces a containing substance list from the mounting component data of the board, and outputs the containing substance list, and the analysis processing is ended (Step S144).
On the other hand, when the board cannot be recognized using the appearance image (NO in Step S143), the analysis object 13 is conveyed to the imaging unit 131. The imaging unit 131 photographs the X-ray tomographic image of the analysis object 13, and the information processor 132 captures the image data of the analysis object 13 (Step S145). The component recognizer 136 performs the component recognition processing on the X-ray tomographic image to specify each component mounted on the board (Step S146). The content in Step S146 is similar to that in Steps S31 to S35 of
In the analysis device of the sixth embodiment, similarly to the first embodiment, the treatment to recover and recycle the specified substance can efficiently be performed because whether specified substances such as noble metals and rare metals are contained in the electronic device or the component mounting board can automatically be determined. The X-ray imaging and the necessity of the component recognition are determined according to the pre-sensing result, so that the processing efficiency can be improved as a whole.
Not the appearance image but the two-dimensional transmission X-ray image in
In the sixth embodiment, whether the X-ray tomographic photographing is performed is determined according to the pre-sensing result. Alternatively, a condition of the X-ray tomographic photographing may be changed according to the pre-sensing result. For example, in the pre-sensing, a thickness of the analysis object is measured with a laser displacement meter, and the number of photographing times or a pitch of the X-ray tomographic photographing may be adjusted according to the thickness. That is, only one layer is photographed for the thin electronic device, and at least two layers are photographed for the thick electronic device. Therefore, the wasted tomographic photographing is eliminated, so that the processing efficiency can be improved as a whole.
An analysis device according to a seventh embodiment has a function of automatically deciding a method for taking out the specified substance from the electronic device or component mounting board. The configuration unique to the seventh embodiment will mainly be described below, and the description of the configuration common to the first to sixth embodiments is omitted.
The configurations of the above embodiments illustrate specific examples of the present invention, but the scope of the present invention is not limited to the configurations of the above embodiments. Various modifications can be made without departing from the scope of the present invention.
For example, in the above embodiments, the X-ray image is used in the component recognition or the board recognition. Alternatively, the image data (such as the visible-light image (appearance image)) except for the X-ray image may be used in the component recognition or the board recognition. In the above embodiments, the position information about the component of the board library is calculated from the image. In the case that design information (such as CAD data) about the electronic device or the board is usable, the design information may be stored in the board data of the board library. In the above embodiments, the data structure of the component library or board library is described only by way of example. However, the database, the data structure of the database, or the data content may be designed anyway as long as the information processing of the present invention can be performed to accomplish the object.
