The inventor has found that a plurality of functional modules of a packaging equipment is required to complete the packaging process together. As an example, during a process of coating an adhesive line, an adhesive coating module and a detecting module are employed together to complete the process. However, in a packaging equipment as illustrated in
An embodiment of the disclosed herein provides a packaging equipment. As illustrated in
In the packaging equipment provided by the embodiment of the disclosed herein, when the movable mechanism drives the package assembly to move, the first rotate mechanism can drive the second functional module to rotate such that the second functional module moves along the predetermined path as well. Due to the above fact, the functional modules of the provided packaging equipment can cooperate with each other in any direction for packaging, thereby meeting the requirements of diversified packaging.
As an example illustrated in
The packaging equipment provided by the embodiment of the disclosed herein can allow the first functional module, the second functional module and the third functional module to move along the predetermined paths simultaneously, thereby making it possible to use three functional modules for packaging simultaneously and increasing the packaging efficiency of the packaging equipment.
It is noted that, the embodiment of the disclosed herein is only described with reference to an exemplary packaging equipment comprising three functional modules. However, more functional modules may be included in the embodiment of the disclosed herein. When more than three of functional modules are included in the packaging equipment, each of the functional modules is fixed to a rotating mechanism rotatable around the first axis. However, it is not limitative to the embodiment of the disclosed herein.
Exemplarily, as illustrated in
The second rotating mechanism 24 comprises a second motor 241. An output shaft of the second motor 241 is fixed to a second driving gear 242, and the second driving gear 242 is engaged with a second driven gear 243. An axis of the second driven gear 243 overlaps with the first axis L. The third functional module 25 is fixed relative to the second driven gear 243.
When the first motor is started, the first motor can drive the first driving gear fixed on the output shaft of the first motor, then the first driving gear drivers the first driven gear engaged with the first driving gear. Moreover, the second functional module is fixed relative to the first driven gear, that is, the first motor can drive the second functional module to rotate around the first axis when being started. Similarly, when the second motor is started, the second motor can drive the second driving gear fixed on the output shaft of the second motor, then the second driving gear drivers the second driven gear engaged with the second driving gear. Moreover, the third functional module is fixed relative to the second driven gear, that is, the second motor can drive the third functional module to rotate around the first axis when being started.
Exemplarily, as illustrated in
As an example, the controller 30 controls the first rotate mechanism 21 and the second rotating mechanism 24 to rotate. Through controlling the first rotate mechanism 21 and the second rotating mechanism 24 to rotate by the controller, that is, controlling the moving paths of the second functional module 23 and the third functional module 25 by the first controller, it can further realize automation and intellectualization of the packaging equipment.
As an example, when the packaging equipment in the embodiment of the disclosed herein comprises the third functional module, the packaging equipment may further comprise: a limit sensor. The limit sensor can send a prompt signal to the controller 30 when a distance between the second functional module and the third functional module is smaller than a predetermined distance.
As an example, when the movable rotating modules are close to each other to a certain distance, the limit sensor triggers an alarm to prevent the two modules from colliding with each other.
The limit sensor can send a prompt signal to the controller 30 when a distance between the second functional module and the third functional module is smaller than a predetermined distance, thereby preventing the second functional module and the third functional module from colliding with each other.
Furthermore, when the packaging equipment in the embodiment of the disclosed herein comprises more functional modules, the limit sensor can monitor distances between multiple functional modules, and send a prompt signal when the distances are less than the predetermined value to prevent the multiple functional modules from colliding with each other.

As an example, the step S502 of controlling the first rotating mechanism or the second rotating mechanism to rotate such that the coated adhesive line is kept within the visual field of the detecting device comprises:
at the same time of the movement of the package assembly, the CCD camera detects whether the center line extending along a length direction of the adhesive line coated by the adhesive line coating head overlaps with the center of view of the CCD camera synchronously; and if they overlap, the movement continues under the current state; if they do not overlap, the CCD camera sends a feedback signal to the controller, and the controller controls the rotating mechanism corresponding to the CCD camera to rotate around the first axis, such that the CCD camera rotates together with the rotating mechanism and the center of the visual field of the CCD camera overlaps with the center line extending along the length direction of the adhesive line.
As an example, a following method may be employed to determine whether the center of visual field of the CCD camera overlaps with the center line extending along a length direction:
detecting, by the CCD camera, respective vertical distances between two side edges of the adhesive line and the center of the visual field of the CCD camera synchronously, if the vertical distances between the two side edges of the adhesive line and the center of the visual field of the CCD camera are equal to each other, the center line extending along the length direction of the adhesive line overlaps with the center of the visual field of the CCD camera; if the vertical distances between the two side edges of the adhesive line and the center of the visual field of the CCD camera are different, the center line extending along the length direction of the adhesive line does not overlap with the center of the visual field of the CCD camera.
As an example illustrated in
The CCD camera in the embodiment of the disclosed herein can detect respective vertical distances between two side edges of the adhesive line and the center of the visual field of the CCD camera synchronously, and obtain a width of the adhesive line coated by the adhesive line coating head. When the adhesive line coated is too wide or too thin, the CCD camera sends a feedback signal to the controller to allow the controller to trigger an alarm. Due to the above fact, the packaging equipment in the embodiment of the disclosed herein can detecting whether the width of the adhesive line qualifies or not while the adhesive line is being coated. The term “qualifies” refers to that the width of the adhesive line coated is within a predetermined range.
As an example, it can create a coordinate system in the embodiment of the disclosed herein such that the adhesive line coated is located in the coordinate system. In this case, it can locate the corresponding position directly according to the coordinate system during subsequent examination and supplementary adhesive coating, which is advantageous to the subsequent examination and supplementary adhesive coating.
As illustrated in
S701: starting the movable mechanism such that the movable mechanism drives the package assembly to move and the adhesive line coating head coats the adhesive line along the predetermined path.
S702: at the same time of the movement of the package assembly, the CCD camera detects a distance between the adhesive line coated by an adhesive line coating head and a panel region synchronously; when the distance between the adhesive line and the panel region deviates from a predetermined value, the CCD camera sends a feedback signal to the controller to allow the controller to trigger an alarm.
As an example illustrated in
In the above embodiment of the disclosed herein, the CCD camera detects the distance between the adhesive line coated by the adhesive line coating head and the panel region synchronously, and sends a feedback signal to the controller to allow the controller to trigger an alarm when the distance between the adhesive line and the panel region deviates from a predetermined value. In this case, the packaging equipment in the embodiment of the disclosed herein can detect whether the position of the adhesive line coated is qualified while the adhesive line is being coated. The term “qualified” refers to that the position of the adhesive line coated is within a predetermined range.
The packaging equipment in the embodiment of the disclosed herein can coat the adhesive line on shapes such as a circle, a rhombus, a rectangle and an arbitrary curve, and monitor the process of coating the adhesive line synchronously.
The second possible implementation:
The movable mechanism of the packaging equipment drives the package assembly to move along a direction vertical to a surface of a component to be packaged, the first functional module is a adhesive line coating head, the second functional module or the third functional module is a laser distance measuring device.

As illustrated in
S901, starting the movable mechanism such that the movable mechanism drives the package assembly to move, and the adhesive line coating head coats the adhesive line along a predetermined path.
S902: at the same time of the movement of the package assembly, the laser distance measuring device measures a distance between the adhesive line on the surface of the component to be packaged and an adhesive line coating head synchronously and sends the measured distance to the controller. If the measured distance accords with a predetermined value, the movement continues in current state, and if the measured distance does not accord with the predetermined value, the controller controls the movable mechanism to drive the package assembly to move along the direction vertical to the surface of the component to be packaged such that the distance between the adhesive line on the surface of the component to be packaged and the adhesive line coating head is equal to the predetermined value.
In the embodiment of the disclosed herein, it can synchronously monitor whether a thickness of the coated adhesive line reaches a predetermined thickness through the adhesive line head and the laser distance measuring device. In this case, it realizes the detecting of the thickness of the coated adhesive line, and allows the packaging equipment to be adapted to nonplanar packaging. Moreover, when the space for coating the adhesive line is very narrow and small which cause a mutual interference between the adhesive line coating head and the laser distance measuring device, it may first use the laser distance measuring device to scan a height and correspond the scanned height to the adhesive line one by one, then coat the adhesive line through the adhesive line coating head.
The third possible implementation:
The first functional module is a CCD camera, the second functional module is a low energy laser cutting head, the third functional module is a high energy laser cutting head, and the controller receives a feedback signal from the CCD camera and controls the rotation angle and the rotation speed of the first rotating mechanism and the second rotating mechanism according to the feedback signal.

S103: at the same time of the movement of the package assembly, detecting, by the CCD camera, whether the actual cutting paths of the low energy laser cutting head and the high energy laser cutting head overlap with the predetermined cutting path synchronously, and sending a feedback signal to the controller to allow the controller to trigger an alarm if the actual cutting paths do not overlap with the predetermined cutting path.
In the embodiment of the disclosed herein, the process of cutting the display is completed through two cutting processes. First the low energy laser cutting head is employed to cut the flexible film of the display, and then the high energy laser cutting head is employed to cut the exposed substrate. At the same time, the CCD camera synchronously detects whether the actual cutting paths of the low energy laser cutting head and the high energy laser cutting head overlap with the predetermined cutting path. In this case, the accuracy of cutting the display can be guaranteed, and two cutting processes can prevent the flexible film disposed on the upper layer of the substrate from the damage by the high energy laser cutting head. Moreover, it can be understood that, the high energy laser cutting head can cut the exposed substrate, which shows that a cutting width of the low energy laser cutting head is larger than that of the high energy laser cutting head.
On the other hand, in the embodiment of the disclosed herein, it allows the moving path of the high energy laser cutting head to overlap with that of the low energy laser cutting head when the packaging equipment moves along arbitrary direction through rotating the second rotating mechanism to drive the high energy laser cutting head to rotate.
