Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.
[0033] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.
[0034] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0035] In this application, unless otherwise clearly specified and defined, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0036] In this application, unless otherwise clearly specified and defined, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher level than the second feature in terms of horizontal height. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is at a lower level than the second feature in terms of horizontal height.
[0037] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.
[0038] Refer to Figure 1 and Figure 2, a detection device 10 provided in an embodiment of the present application is used to detect a workpiece 20. The detection device 10 includes a base frame 100, a detection module 200, a conveying component 300, and a handling component 400. Among them, the detection module 200 and the handling component 400 are arranged on the base frame 100. The base frame 100 is provided with a movable detection table 110, which is used to support the workpiece 20 and drive the workpiece 20 to move. The detection table 110 is provided with a detection position 11. The detection module 200 is arranged on the base frame 100, and the field of view of the detection module 200 covers the detection position 11 to detect the workpiece 20. The conveying component 300 is used to convey the workpiece 20, and the conveying component 300 is provided with a picking and placing position 12. The handling component 400 is movably arranged on the base frame 100, and the handling component 400 is used to move the workpiece 20 between the picking and placing position 12 and the detection position 11.
[0039] In the above detection device 10, the field of view of the detection module 200 covers the detection position 11, so the detection module 200 can perform external shape detection on the workpiece 20 located at the detection position 11. Moreover, when the detection table 110 moves, it can drive the workpiece 20 to move on the base frame 100. Then, when the workpiece 20 moves with the detection table 110, the workpiece 20 can present different postures and angular orientations within the field of view of the detection module 200. Thus, different parts of the workpiece 20 and different local areas of the same part can all be within the field of view of the detection module 200. Therefore, there is no need to set multiple visual detectors 210 to separately detect the external shape of the workpiece 20, relatively reducing the number of visual detectors 210, making the detection device 10 have a simpler structure and lower cost.
[0040] In one embodiment, the workpiece 20 can be a battery module. Of course, the same is true when the workpiece 20 is other materials that need to be subjected to external shape detection, so it will not be elaborated here.
[0041] As Figure 3 , in one embodiment, the detection table 110 can perform rotational movement, and the detection table 110 can rotate to different sides in its circumferential direction to face the detection module 200. Thus, it is not necessary to arrange visual detectors 210 at various circumferential positions of the detection position 11, so the structure of the detection device 10 is relatively simplified and the cost is reduced. Further, the detection table 110 can include a support table 111 and a rotation drive 112. The support table 111 is rotatably arranged on the base frame 100, and the detection position 11 is arranged on the support table 111. When the support table 111 rotates, it can drive the workpiece 20 to move together, so as to make different sides of the workpiece 20 face the detection module 200. The rotation drive 112 is connected to the support table 111 and is used to drive the support table 111 to rotate.
[0042] Of course, in other embodiments, the inspection table 110 can also perform a translational movement, that is, the inspection table 110 can be translated so that different regions on the outer surface of the inspection table 110 are within the field of view of the inspection module 200. It is easy to understand that when the surface of the workpiece 20 has a large area range, in order to ensure the inspection accuracy, multiple cameras are usually set to inspect different regions respectively. Such a setting in this embodiment can make different regions within the field of view, so there is no need to set multiple vision detectors 210 to inspect respectively, which simplifies the structure and reduces the cost. Of course, in some embodiments, the inspection table 110 can be configured to be able to rotate and translate simultaneously.
[0043] Please refer to Figure 1 , in one embodiment, the base frame 100 includes a base 101 and a bracket 102, and the bracket 102 is integrally mounted on the base 101. The inspection table 110 is rotatably provided on the base 101, and the handling assembly 400 is movably provided on the bracket 102, so that the handling assembly 400 can conveniently transport the workpiece 20 to the inspection table 110.
[0044] Please refer to Figures 4 to 6 , in one embodiment, the handling assembly 400 includes a jaw part 410. The jaw part 410 includes a carrier plate 411 and a jaw structure 412. The jaw structure 412 is provided on the carrier plate 411, and the jaw structure 412 is used to pick up the workpiece 20. The jaw structure 412 is rotatable relative to the carrier plate 411 and is used to bring different sides of the workpiece 20 into contact with the inspection table 110. Since the jaw structure 412 is used to pick up the workpiece 20 and is rotatable relative to the carrier plate 411, the jaw structure 412 can drive the workpiece 20 to rotate together when it rotates. Therefore, as Figure 3 and Figure 6 , the posture of the workpiece 20 when it is in the inspection position 11 can be adjusted through the jaw structure 412 (such as the lying posture shown in Figure 3 and the standing posture shown in Figure 6 ), so that different circumferential side surfaces of the workpiece 20 are within the field of view of the inspection module 200 when the inspection table 110 rotates. And it is easy to understand that since the workpiece 20 is placed on the inspection table 110, at least one side surface of the workpiece 20 is in contact with the inspection table 110 and cannot be detected by the inspection module 200. In this embodiment, by setting the jaw part 410 to be rotatable, the posture of the workpiece 20 on the inspection table 110 can be adjusted. For the adjusted workpiece 20, the originally blocked surface can be within the field of view of the inspection module 200, so the comprehensiveness of the inspection is improved.
[0045] Please refer to Figure 2 , Figure 4 and Figure 5, in one embodiment, the direction in which the pick-and-place position 12 points to the detection position 11 is the first direction S1. The handling assembly 400 further includes a first moving member 420. The first moving member 420 extends along the first direction S1 and is disposed on the base frame 100. The first moving member 420 is connected to the jaw member 410 to drive the jaw member 410 to move along the first direction S1. Thus, after the jaw member 410 picks up the workpiece 20, the first moving member 420 can drive the workpiece 20 to move to the detection position 11 to place the workpiece 20 in the detection position 11 for detection.
[0046] Further, the handling assembly 400 further includes a second moving member 430. The second moving member 430 is connected between the first moving member 420 and the jaw member 410, that is, the jaw member 410 is connected to the first moving member 420 through the second moving member 430. The second moving member 430 is connected to the jaw member 410 and is used to drive the jaw member 410 to move along the second direction S2, so that the jaw member 410 approaches or moves away from the pick-and-place position 12 along the second direction S2, and approaches or moves away from the detection position 11. Wherein, the second direction S2 intersects with the first direction S1. Further, the second direction S2 and the first direction S1 may be perpendicular to each other. When the detection device 10 is in normal use, the second direction S2 may be the direction of gravity.
[0047] Please refer to Figure 4 , in one embodiment, the first moving member 420 includes a first slide rail 421 and a first driver (not shown in the figure, the same below). The first slide rail 421 extends along the first direction S1 and is disposed on the bracket 102. The second moving member 430 is slidably engaged with the first slide rail 421, and the first driver is used to drive the second moving member 430 to move along the first direction S1.
[0048] Please refer to Figure 5 , in one embodiment, the second moving member 430 includes a connecting plate 431 and a second driver 432. The connecting plate 431 is slidably engaged with the first slide rail 421. The second driver 432 is disposed on the connecting plate 431 and is connected to the jaw member 410. The second driver 432 is used to drive the jaw member 410 to move along the second direction S2. Further, the second driver 432 may be connected to the carrier plate 411 to indirectly drive the jaw structure 412 to move.
[0049] Please refer to Figure 7, in one embodiment, the jaw component 410 further includes a third driver 417. The carrier plate 411 is provided with a second slide rail 411a. Both jaw structures 412 are slidably engaged with the second slide rail 411a. The third driver 417 is configured to drive the two jaw structures 412 to move towards each other along the second slide rail 411a to clamp the workpiece 20 or move away from each other to release the workpiece 20. The second slide rail 411a can be disposed on the carrier plate 411 extending along a third direction S3, where the third direction S3 can intersect both the second direction S2 and the first direction S1. Further, the first direction S1, the second direction S2, and the third direction S3 are perpendicular to each other in pairs.
[0050] Please refer to Figure 5 and Figure 7 , in one embodiment, the jaw structure 412 includes an adapter plate 413, a carrier plate 414, and a clamping portion 415. The adapter plates 413 of the two jaw structures 412 are both slidably engaged with the carrier plate 411 to move towards or away from each other. The carrier plate 414 is rotatably disposed on the adapter plate 413, and a plurality of clamping portions 415 are slidably disposed on the carrier plate 414 to clamp or release the workpiece 20. That is, not only can the two jaw structures 412 move towards each other to clamp the workpiece 20, but also a single jaw structure 412 can clamp the end of the workpiece 20 through the cooperation of a plurality of clamping portions 415 to improve the stability of the jaw component 410 picking up the workpiece 20. After the clamping portion 415 picks up the workpiece 20, the carrier plate 414 rotates relative to the adapter plate 413 to adjust the side surface of the workpiece 20 in contact with the inspection table 110, thereby realizing the adjustment of the attitude of the workpiece 20 on the inspection table 110.
[0051] Such as Figure 5 , further, the jaw structure 412 further includes a fourth driver 418. The fourth driver 418 is disposed on the adapter plate 413 and connected to the carrier plate 414. The fourth driver 418 can drive the carrier plate 414 to rotate. The jaw structure 412 is further provided with a fifth driver 419. A plurality of fifth drivers 419 are respectively connected to a plurality of clamping portions 415 to drive the respective clamping portions 415 to move.
[0052] Please refer to Figure 7 , in one embodiment, among the plurality of clamping portions 415, there are a first clamping portion 415a, a second clamping portion 415b, and a third clamping portion 415c. The first clamping portion 415a and the second clamping portion 415b are disposed facing each other and slidably engaged with the carrier plate 414 along the same direction to clamp the workpiece 20, improving the stability of the position of the workpiece 20 after the jaw component 410 picks up the workpiece 20. The sliding direction of the third clamping portion 415c on the carrier plate 414 intersects the sliding direction of the first clamping portion 415a. The third clamping portion 415c is used to fit and support the workpiece 20 to further improve the position stability of the workpiece 20. Further, the sliding direction of the third clamping portion 415c on the carrier plate 414 is perpendicular to the sliding direction of the first clamping portion 415a.
[0053] Furthermore, the clamping jaw structure 412 includes a plug-in column 416, which is provided on the side of the bearing plate 414 facing the workpiece 20, and the plug-in column 416 is used to be plugged with the workpiece 20 for positioning. In this way, on the one hand, the plug-in column 416 can be plugged with the workpiece 20 to improve the position accuracy of the workpiece 20 when the clamping jaw structure 412 clamps the workpiece 20. On the other hand, the plug-in column 416 is plugged with the workpiece 20, and the plug-in column 416 can limit the position of the workpiece 20 to further improve the position stability of the workpiece 20.
[0054] It should be noted that the transport component 400 can not only pick up the workpiece 20 at the pick-and-place position 12 and place it at the inspection position 11 , but can also pick up the workpiece 20 after inspection and return it to the pick-and-place position 12 to facilitate unloading of the workpiece 20 .
[0055] See also Figures 8 to 10 In one embodiment, the feeding component 310 includes a stand 311 and a conveying member 312, and the conveying member 312 is arranged on the stand 311 to drive the workpiece 20 to move. The two stands 311 are arranged opposite to each other and spaced apart, and the stand 311 is provided with a conveying plane PL for the workpiece 20 to move. The conveying member 312 can be a conveyor belt or a double-speed chain for driving components.
[0056] The conveying assembly 300 includes a limiting structure 320, which includes a limiting member, which is movably disposed between the two upright frames 311. The limiting member can be raised to a position intersecting with the conveying plane PL to limit the workpiece 20 at the pick-up and placement position 12, and the limiting member can be lowered to a position offset from the conveying plane PL. By limiting the workpiece 20 with the limiting member, the workpiece 20 can be stably placed at the pick-up and placement position 12.
[0057] See also Figure 8 and Figure 13 In one embodiment, the conveying assembly 300 further includes a tray 330, and the tray 330 is used to support the workpiece 20, and the feeding component 310 drives the tray 330 to move. It can be understood that if the workpiece 20 is set to directly contact and transmit with the conveying member 312, the workpiece 20 may be damaged during the contact and friction with the conveying member 312. Therefore, in each embodiment of the present application, the workpiece 20 can be set on the tray 330, and the tray 330 moves under the drive of the conveying member 312. At this time, the limiter can limit the position of the workpiece 20 by abutting against the tray 330. Of course, for some workpieces 20 with hard surfaces or low precision requirements, they can also be directly contacted and transmitted with the conveying member 312.
[0058] See also Figure 9 and Figure 10In one embodiment, the limiting structure 320 includes a first beam 321, the first beam 321 is connected between the two frames 311, and the limiting member is arranged on the first beam 321. The limiting member includes a limiting driver 322 and a stopper 323, the stopper 323 is rotatably connected to the first beam 321, and the limiting driver 322 is connected to the stopper 323 to drive the stopper 323 to rotate. The stopper 323 can rotate to a position intersecting with the conveying plane PL (such as Figure 9 As shown) to abut against the tray 330, and the stopper 323 can be rotated to a position away from the conveying plane PL (as shown) Figure 10 As shown). The rotation direction of the stopper 323 is as follows Figure 9 and Figure 10 The middle arrow R1. The portion of the stopper 323 used to abut against the tray 330 may be provided with a rolling portion 324, and the rolling portion 324 is used to contact the tray 330 to improve the stability of the limit. The following embodiments will also mention the limiting effect of the stop structure 340 on the workpiece 20, which also refers to the indirect limiting of the workpiece 20 through the tray 330, which will not be repeated below.
[0059] See also Figure 8 and Figure 11 In one embodiment, the feeding component 310 drives the workpiece 20 to be transported along the conveying direction K, and the conveying direction K may be parallel to the third direction S3. The limiting structure 320 further includes a stop structure 340, and the stop structure 340, the limit structure 320 and the two vertical frames 311 together form a pick-up and placement position 12. In the conveying direction K, the stop structure 340 is located upstream relative to the limit structure 320 and contacts the workpiece 20 first. The side of the stop structure 340 facing the limit structure 320 is used to abut against the workpiece 20 to limit the workpiece 20 from retreating in the conveying direction K. In this way, the workpiece 20 can be limited to the pick-up and placement position 12 by the stop structure 340, the limit structure 320 and the two vertical frames 311, so as to be picked up by the handling assembly 400. The upstream means that the feeding component 310 drives the workpiece 20 to move along the conveying direction K, and always passes through the stop structure 340 first and then the limit structure 320.
[0060] See also Figure 11 and Figure 12 In one embodiment, the stop structure 340 includes a second beam 341 , a base 342 and a flip block 343 , the flip block 343 is disposed on the base 342 , the base 342 is disposed on the second beam 341 , and the second beam 341 is connected between the two frames 311 .
[0061] The flip block 343 includes a stopper vertical surface 344 facing the pick-and-place position 12 and an introduction surface 345 away from the pick-and-place position 12. The flip block 343 is rotatably disposed on the base 342 to move between an initial position and an avoidance position. The direction in which the flip block 343 rotates relative to the base 342 is as follows: Figure 12As shown by the middle arrow R2. When the flip block 343 is in the avoidance position, the flip block 343 is located on the side of the conveying plane PL away from the workpiece 20, and at this time, the flip block 343 does not limit the workpiece 20 moving on the conveying plane PL. When the flip block 343 is in the initial position, the stop vertical surface 344 intersects with the conveying plane PL to abut the workpiece 20. At this time, in the conveying direction K, at least part of the area of the introduction surface 345 is located on the side of the conveying plane PL facing the workpiece 20, and the side of the introduction surface 345 close to the stop vertical surface 344 is higher than the other side, and the introduction surface 345 is used to be pushed by the workpiece 20 and flipped to the avoidance position. In this way, when the workpiece 20 moves along the conveying direction K to the pick-up and placement position 12, it can automatically pass over the stop structure 340, and the workpiece 20 in the pick-up and placement position 12 cannot retreat.
[0062] Furthermore, the flip block 343 can automatically reset to the initial position. It is understandable that when the tray 330 moves toward the pick-up and placement position 12 along the conveying direction K, it can resist the movement of the flip block 343 to move over the flip block 343 to the pick-up and placement position 12. When the tray 330 is in the pick-up and placement position 12, the tray 330 no longer acts on the flip block 343, and the flip block 343 is reset to the initial position to limit the retreat of the tray 330. For example, the stop structure 340 can be set to also include a reset member (not shown in the figure, the same below), and the reset member elastically abuts between the flip block 343 and the base 342 to elastically resist the flip block 343 in the direction of movement to the initial position. The reset member can be configured as a compression spring.
[0063] See also Figure 13 and Figure 14 In one embodiment, the conveying assembly 300 further includes a lifting component 350, which is located between the two upright frames 311 and arranged below the pick-up and placement position 12. The lifting component 350 is provided with a plurality of positioning pins 351, and the tray 330 is provided with a plurality of positioning holes (not shown in the figure, the same below). After the lifting component 350 is lifted up, the plurality of positioning pins 351 are correspondingly plugged and positioned with the plurality of positioning holes. In this way, the position accuracy of the tray 330 at the pick-up and placement position 12 can be improved through the cooperation between the positioning pins 351 and the positioning holes, so as to improve the position accuracy of the workpiece 20 and facilitate the picking up by the clamping claw component 410.
[0064] See also Figure 14 In one embodiment, the lifting component 350 includes a bottom plate 352, a support plate 353 and a lifting driver 354. The bottom plate 352 is connected to the two brackets 102. The lifting driver 354 is disposed on the bottom plate 352 and connected to the support plate 353 to drive the support plate 353 to move up and down. The positioning pin 351 is disposed on the support plate 353, and the support plate 353 is used to lift the tray 330.
[0065] See also Figure 2 and Figure 15, in one embodiment, the detection module 200 includes a plurality of detectors 210, and the plurality of detectors 210 are distributed around at least two sides of the detection position 11. The detection module 200 further includes a plurality of guide rails 220, and the detectors 210 are arranged on the guide rails 220 and can slide along the guide rails 220 to expand the detection range. The various detectors 210 can be configured to have different detection characteristics. For example, the detector 210 can be configured as a area array camera, a line scan camera, or a 3D camera, etc.
[0066] Of course, the detector 210 is not limited to being arranged on the base 101, and the detector 210 can also be arranged on the bracket 102.
