According to an embodiment of the present disclosure, there is provided an attitude adjustment structure including: a base body, arranged in an X direction, the base body having a bearing surface, and the bearing surface being configured to place a detected object; and a first adjustment assembly, arranged below the base body, wherein the first adjustment assembly includes: a rack, slidable in the X direction relative to the base body; a turning lever, rotatably arranged on the rack with the Y axis as a rotation axis; and a turning head, arranged on the turning lever and allowed to abut against the detected object under a driving of the driving rod to drive the detected object to deviate around a Y direction on the bearing surface, and/or drive the detected object to move in the X direction on the bearing surface.
The attitude adjustment structure of the present disclosure may be used to adjust a movement attitude of an object conveyed on a production line; it may also be used in the field of radiation detection to adjust a detected object to a preset detection position. In the application of the field of radiation detection, the attitude adjustment structure in the present disclosure needs to be used in at least the following scenarios. The scenarios are described as follows:
It may be understood that in the field of radiation detection, the radiation imaging technology may perform an imaging on a damage of an internal portion of an object to facilitate judgment by an inspector. In the detected objects, there are regions to be detected having a small detection dimension. For example, in a detection process of a lithium battery, a thin film or an adhesive layer of the lithium battery needs to be detected. But a thickness of the thin film or the adhesive layer of the lithium battery is small. As shown in
Based on the above problems, as shown in
Referring to
Referring to
As shown in
The detected object 4 in the embodiments of the present disclosure may be a lithium battery. When the lithium battery is placed on the bearing surface 11, it is necessary to ensure that a plane where a thickness of an adhesive layer or a film layer thereof is located is substantially arranged to face the ray machine of the imaging system.
Referring to
It may be understood that, in some implementation manners, the sliding blocks 52 may also be mounted on the rack 21, and the sliding rail 51 may be mounted on the base body 1.
It may be understood that driving of an external force may be a manpower driving, an electric driving, a hydraulic driving, a pneumatic driving and the like.
In the embodiment of the present disclosure, the first adjustment assembly 2 further includes a rotating member. The rotating member is rotatably arranged on the rack 21 with the Y axis as a rotation axis and used to drive the detected object to deviate around the Y direction on the bearing surface under a driving of an external force, and drive the detected object to move in the X direction under a leading of the rack 21.
It may be understood that there may be various structures and forms of the rotating member. The rotating member in the embodiments of the present disclosure is in a form of a combination of a turning lever and a turning head, and the specific structure is as follows:
As shown in
It may be understood that, in order that the turning lever 22 may be rotatably mounted on the rotating shaft 211, in the embodiments of the present disclosure, the turning lever 22 is arranged on an adapter block 25, and two turning levers 22 are respectively arranged on the adapter block 23 opposite to each other. An mounting hole is processed at a middle position of the adapter block 25, and the mounting hole is embedded with a bearing and a retaining ring 27 for restricting the bearing from coming out of the mounting hole. The rotating shaft 211 is matched and mounted in the bearing, so as to achieve a rotation of the adapter block 25 around the rotating shaft 211 and lead a rotation of the turning lever 22 around the Y direction.
As shown in
In the embodiments of the present disclosure, the turning heads 23 are respectively mounted at ends of the two turning levers 22. The turning heads 23 protrude from the bearing surface 11, and may abut against an end face of the detected object 4 in a direction of a backward movement when the rack 21 moves. Moreover, in order to achieve a deviate of the detected object 4, an abutment position of the turning head 23 deviates from a central position of the end surface.
It may be understood that the process of driving the detected object 4 on the bearing surface 11 to deviate around the Y direction by the turning head 23 is as follows. When the rack 21 moves to the detected object 4 driven under a driving of external force, if a deviate of the detected object in the Y direction is deviated, the adapter block 25 rotates, and leads the turning lever 22 to rotate, so that the turning head 23 on the turning lever 22 acts on the detected object 4 and the turning head 23 pushes the detected object 4 to rotate, thereby achieving a correction of the deviate of the detected object 4. The detection method of whether the detected object 4 has deviated in the Y direction may be detected by a position sensor to detect spatial position coordinates of a current detected object 4 to determine whether it has deviated. It may also be determined by a detection result of a previous detected object 4. If the detection result of the previous detected object 4 is an occurrence of deviating, then a deviating adjustment needs to be performed on the current detected object 4.
It may be understood that after the deviate correction of the detected object 4 is completed, when the rack 21 continues to move in the X direction, the turning head 23 may push the detected object 4 to move in the X direction to enter the next detection step.
It may be understood that, in some embodiments, under a driving of the turning lever 22, the turning head 23 may only abut against the detected object 4 to drive the detected object 4 to deviate around the Y direction on the bearing surface 11. The movement of the detected object 4 in the X direction may be driven by other structures.
It may be understood that, in some embodiments, the rotating member may also be a combination of a turntable and a lifting structure. Specifically, the turntable is arranged on the lifting structure. Under a leading of the lifting structure, the turntable 21 may move up and down in the Y direction. When the turntable 21 rises, it may bear the detected object 4 on the base body 1. At the same time, the turntable is rotatably arranged on the lifting structure. Under a driving of an external force, the turntable bearing the detected object 4 may rotate around the Y direction. Further, the lifting structure is fixed on the rack 1, and under a leading of the rack 1, the turntable may also move in the X direction, so as to achieve an adjustment of the deviate of the detected object in the Y direction.
In the embodiments of the present disclosure, the first adjustment assembly 2 further includes a first driving unit 26, where the first driving unit 26 is used to push a rotation of the adapter block 25, and specifically, the first driving unit 26 has a pushing rod 261 that may move toward or away from the adapter block 25, and a first motor 262. An end of the pushing rod 261 is movably connected to the adapter block 25, and the other end thereof is connected to the first motor 262. In order to ensure that the pushing rod 261 may push the adapter block 25 to rotate around the rotating shaft 211, the push rod 261 needs to be connected to an end of the adapter block 25 away from the rotating shaft 211 to form a rotational moment during pushing.
Referring to
It may be understood that two sets of first driving units 26 are provided in the embodiments of the present disclosure, and they are arranged symmetrically with respect to the rotating shaft 211. When the two sets of first driving units 26 drive the turning lever 26 to move, a pushing rod 261 of one first driving unit 26 moves towards the turning lever 26, and the pushing rod 261 of the other first driving unit 26 moves away from the turning rod 26.
It may be understood that in some other embodiments, the quantity of the first driving unit 26 may be one set. When one set of the first driving unit 26 is provided, the pushing rod 261 and the adapter block 25 may be adjusted through a cooperation of a telescopic rod with a universal joint to achieve a reciprocating swing of the turning lever 22 around the Y direction.
It may be understood that, in some implementation manners, the quantity of the turning heads 23 mounted on the turning lever 22 may be multiple, so as to adjust a position of turning.
As described above, in the embodiments of the present disclosure, when the rack 21 moves, it has a function of pushing the detected objects 4 to move in the X direction through the turning head 23, and the detected objects 4 are arranged on the base body 1 at intervals. When the rack 21 drives a previous detected object 4 to move to the next process in the X direction, the rack 21 may be driven back, and the turning head 23 is allowed to abut against the end face of the detected object 4 in a direction of a backward movement again, so as to push the detected object 4 to move in the X direction. In order to achieve a continuous conveying of the detected object 4 on the base body 1 by the first adjustment assembly 2, in the embodiments of the present disclosure, the turning head 23 is also needed to be rotatably arranged on the turning lever 22, rotatable around an axis direction of the turning lever 22, and configured as an eccentric structure. The turning head 23 has a first position protruding from the bearing surface 11 under a driving of an eccentric force and a second position turned below the bearing surface under an action of an external force. When the rack 21 moves in the X direction, the turning head 23 at the first position is used to push the detected object to move in the X direction.
As shown in
As shown in
In the embodiments of the present disclosure, a material incoming manner of the detected object 4 is that one detected object is conveyed from a material incoming point of the base body 1 every certain time interval. However, the distance between the material incoming point of the detected object 4 and the imaging region is relatively long, as a result, a travel of the rack 21 moving forward or backward between the material incoming point and the imaging region is relatively long, and this increases a conveying time of the detected object 4. In order to solve the above problem, in the embodiments of the present disclosure, a turning head 23 is rotatably arranged at an end of the rack 21 away from the first adjustment assembly 2, and the turning head 23 and the turning head in the first assembly 2 are arranged at an interval in the X direction. A distance of the interval described above may be half of a distance from the material incoming point to the imaging region. When the rack 21 retreats for a distance of an interval, and advances again, two detected objects 4 may be led to move forward at one time, so that the conveying efficiency of the detected object 4 is improved.
It may be understood that when there are multiple material incomings of the detected objects at one time, a plurality of turning heads 23 may be adaptively arranged in the X direction, so as to improve the conveying efficiency of the detected objects 4.
As described above, when the detected layer of the film or the adhesive layer (the detection surface parallel to the main beam plane) is deviated in the Z direction, due to the influence of the shape of the imaging region, there may be situation that the detected layer is deviated out of the imaging region. On this basis, in the embodiments of the present disclosure, there is further provided a second adjustment assembly 3. After a deviate correction of the detected object 4 in the Y direction is completed on the first adjustment assembly 2, the detected object 4 enters into the second adjustment assembly 3 under a push of the turning head 23.
The second adjustment assembly 3 is arranged on the base body 1. The second adjustment assembly includes: a supporting plate 31, rotatably arranged on the base body 1 with the Z axis as a rotation axis and configured to bear the detected object thereon. In the embodiments of the present disclosure, the supporting plate 31 is a supporting beam structure. In order to achieve a stable support to the detected object 4, there are two supporting plates 31 respectively provided on the base body 1 in a hinged manner. Hinge seats 33 are respectively arranged on the horizontal supporting arms of two frame bodies 12 of the base body 1 correspondingly, so as to achieve a connection with the supporting plate 31.
Referring to
As shown in
As shown in
It may be understood that the driving form of the second driving unit 32 may be various, and in some embodiments, common pushing rod motor driving, cylinder telescopic driving and the like are used.
As shown in
It should be noted here that the rays in a radiation imaging are prone to attenuation when passing through a metal object, and therefore structures such as the supporting plate 31 in the second adjustment assembly 3 in the present embodiment are preferably made of carbon fiber materials.
It should be noted that the inventors found in the actual production that the rigidity of the supporting plate 31 made of carbon fiber is ordinary, and after multiple times of uses, the supporting plate 31 is prone to a bending deformation. When different types of detected objects are placed on the supporting plate 31, affected by weight changes of the detected objects 4, degrees of bending deformation of the supporting plate 31 are different, and a rotation angle of the supporting plate 31 needs to be adjusted every time. This increases the operation processes. On this basis, an implementation manner of another second adjusting assembly 3 is provided in the present disclosure.
As shown in
The first adjustment assembly in the present disclosure achieves a deviating adjustment of the detected object in the Y direction, and may push the detected object to move in the X direction; and the second adjustment assembly achieves a deviating adjustment of the detected object in the Z direction. Under actions of the first adjustment assembly and the second adjustment assembly, the detected object may be adjusted to a state suitable for a detection. When the attitude adjustment structure in the present disclosure is used in the radiation imaging system for a film or an adhesive layer detection as introduced in the background technology, by a deviating adjustment of the detected object, it may be ensured that the main beam surface of the light beam generated by the ray machine is parallel to the detected layer surface of the detected object, so that the accuracy of detection is guaranteed.
A conveying device is further provided in the embodiments of the present disclosure. The conveying device includes the attitude adjustment structure in the above embodiments. In the X direction, the conveying device may at least include a first section and a second section arranged at a front end and a rear end of the attitude adjustment structure. The first section of the conveying device is responsible for conveying an object 4 to be detected to the bearing surface 11 of the base body 1, and the second section thereof is responsible for conveying the detected object 4 on the second adjustment assembly 3 to a subsequent process after a radiation imaging process is completed. Belt conveyors, roller conveyors, etc. may be used as the first section of the conveying device and the second section of the conveying device.
A radiation imaging system is further provided in the embodiments of the present disclosure, specifically a CT imaging system. Of course, the present device is also applicable to a DR imaging system. The radiation imaging system includes the conveying device described above and a scanning device. The scanning device is arranged on two sides of the second adjustment assembly 3. After the detected object 4 is adjusted to a preset detection position by the attitude adjustment structure, a ray machine in the scanning device emits X-rays towards the detected object 4, the X-rays pass through the detected object 4 and are received by a detector located at the other end of the detected object 4 to complete scanning and imaging. An image reconstruction is completed by processing scanned data, and a reconstructed image is displayed to an inspector for a judgment of a detection result of the detected object 4.
