[0011] In one of the embodiments, the positioning structure comprises a second driver and a supporting plate, a plurality of the positioning members are arranged at the supporting plate and correspond to a plurality of the jigs one by one, the second driver is connected with the supporting plate to drive the supporting plate to move along the positioning direction, the positioning direction intersects with the reference direction.
[0012] In one of the embodiments, the supporting plate is provided with a plurality of sliding grooves extending along the positioning direction, a plurality of the positioning members are arranged in the sliding grooves one by one and the positions in the sliding grooves are adjustable.
[0013] In one of the embodiments, the positioning member comprises a connecting plate, a push block and an elastic member. The connecting plate is provided with a limiting slot.

[0034] Reference Figure 1 , Figure 1A side view of a detection apparatus is shown. The detection apparatus 10 is used for appearance detection and dimension measurement of a workpiece. The detection apparatus 10 includes a carrying device 11 and a detection module 12. The carrying device 11 is used for picking up the workpiece, and the detection module 12 is used for appearance detection and dimension measurement of the workpiece. The number of the carrying devices 11 can be one or more.
[0035] Please continue to refer to Figure 1 In one embodiment, the detection apparatus 10 further includes a driving platform 13 connected with the carrying device 11 to drive the single or multiple carrying devices 11 to move to the detection range of the detection module 12.
[0036] Please refer to Figures 2 to 4 The carrying device 11 includes a support structure 100, a picking module 200, a driving structure 300 and a positioning structure 400. The picking module 200, the driving structure 300 and the positioning structure 400 are all arranged on the support structure 100. The support structure 100 includes a mounting plate 110 having a first side 111 and a second side 112 arranged oppositely. The driving structure 300 is arranged on the first side 111, and the positioning structure 400 is movably arranged on the second side 112. The picking module 200 includes a driven member 210, a connecting shaft 220 and a jig 230. The connecting shaft 220 is rotatably arranged through the mounting plate 110. One end of the connecting shaft 220 is located on the first side 111 and is in transmission connection with the driven member 210. The other end of the connecting shaft 220 is located on the second side 112 and is in transmission connection with the jig 230. The driven member 210 is provided with transmission teeth on the outer periphery. The driving structure 300 includes a movable driving member 310 also provided with transmission teeth. The driving member 310 and the driven member 210 are in meshing transmission through the transmission teeth to drive the driven member 210 to rotate. The jig 230 is used for picking up the workpiece and is provided with a reference part 231. The positioning structure 400 is used for pushing the workpiece located on the jig 230 to a position in contact with the reference part 231 to position the workpiece.
[0037] The mounting plate 110 has a first side 111 and a second side 112 opposite to each other. The driving structure 300 is arranged on the first side 111 and is in transmission connection with the driven member 210, so that the driving structure 300 can drive the pick-up module 200 to rotate. The positioning structure 400 is arranged on the second side 112 and can position the workpiece on the jig 230 to the expected position. Since the driving structure 300 and the positioning structure 400 having movement ability are arranged on the opposite sides of the mounting plate 110 respectively, the movement of the two will not interfere with each other. Thus, the carrying device 11 can not have to be configured to have a larger structure size in order to coordinate the movement range of the two. In short, such arrangement can make the carrying device 11 have a smaller structure size and be more flexible in movement, and be convenient for carrying the workpiece. It should be noted that since the connecting shaft 220 is arranged through the mounting plate 110 and the two ends of the connecting shaft 220 are located on the first side 111 and the second side 112 respectively, the connecting shaft 220 can drive the driven member 210 on the first side 111 and the jig 230 on the second side 112 to be in transmission connection together, so that the pick-up module 200 moves as a whole.
[0038] Further, in the prior art, the jig 230 is usually driven to move by a transmission mode such as belt transmission which utilizes friction. Since the transmission mode is not tight enough, under the action of inertia, the relative movement between the jig 230 and the transmission belt is easy to occur when starting and stopping, and the position of the jig 230 is uncertain. Since the jig 230 is used to pick up the workpiece, the position of the jig 230 corresponds to the position of the workpiece. For detection and measurement, when the workpiece cannot be accurately moved to the expected position, the workpiece cannot be fully exposed to the detection range of the detection module 12, so that the detection is not sufficient and the problem of false reporting of defective products is easy to occur. Compared with the transmission mode such as belt transmission which utilizes friction in the prior art, the transmission in the present application is realized by the meshing of transmission teeth, and the transmission teeth are more tightly matched and are not easy to loosen. Such arrangement can improve the movement precision and the position accuracy of the jig 230 and the workpiece picked up by the jig 230, so that the detection is more accurate and the false reporting rate of defective products is reduced.
[0039] Please refer to Figure 5In one embodiment, the transmission between the driven member 210 and the driving member 310 can include, but is not limited to, a rack and pinion transmission, a worm and gear transmission, and a bevel gear transmission. Further, the driven member 210 can be configured as a pinion, and the driving member 310 can be configured as a rack that is adapted to engage the pinion. The parameters of the pinion and the rack can be adjusted so that the driving member 310 and the driven member 210 have a reverse self-locking characteristic when they are in transmission, i.e., the driving member 310 can drive the driven member 210 to rotate, but the driven member 210 cannot drive the driving member 310 to move in the reverse direction, so as to further improve the position stability and accuracy of the jig 230. For example, the tooth profile angle of the transmission teeth can be adjusted, the module of the pinion and the rack can be reduced, materials with a large friction coefficient can be selected for the pinion and the rack, or the tooth surface of the transmission teeth can be surface treated, and the transmission ratio between the pinion and the rack can be adjusted. When the jig 230 does not have a requirement for a full rotation, the transmission teeth can also be distributed only in a partial area of the outer periphery of the driven member 210, i.e., the driven member 210 is an incomplete pinion at this time.
[0040] Referring to Figure 4 In one embodiment, the driving structure 300 further includes a first driver 320 connected with the driving member 310 to drive the driving member 310 to move. Further, the first driver 320 can also be configured to have a self-locking characteristic.
[0041] Referring to Figure 5 In one embodiment, the carrying device 11 includes a plurality of pickup modules 200 that are spaced apart along the reference direction K. The driving member 310 simultaneously engages and transmits with the driven members 210 of the plurality of pickup modules 200. In combination with the above, the driving member 310 is configured as a rack, which can facilitate simultaneous engagement and transmission with the driven members 210 of the plurality of pickup modules 200.
[0042] In one embodiment, the transmission teeth can also be configured as helical teeth, i.e., the driven member 210 is a helical pinion, and the driving member 310 is a helical rack, so as to have a higher reduction ratio and facilitate simultaneous driving of the plurality of driven members 210 to rotate.
[0043] In one embodiment, the pickup module 200 can be configured to pick up a workpiece in a vacuum suction manner, so as to pick up workpieces with different shapes. Since the carrying device 11 includes the positioning structure 400, the pickup module 200 picks up the workpiece in the vacuum suction manner, and the workpiece can also be positioned by the positioning structure 400 to stably be in an expected position. Referring to Figure 4Further, the pickup module 200 is provided with a suction passage 201, one end of the suction passage 201 is connected to the negative pressure generator, and the other end of the suction passage 201 is provided with a suction hole 230b on the side end face of the jig 230 away from the driven member 210. The reference part 231 is arranged on the circumferential outer side of the area where the suction hole 230b is located, and the reference part 231 cooperates with the positioning structure 400 to position the workpiece at a position that can block the suction hole 230b, so that the suction hole 230b is used to adsorb the workpiece blocked by the workpiece.
[0044] Please continue to refer to Figure 4 In one embodiment, the connecting shaft 220 can be configured as a hollow structure to form part of the flow section of the suction passage 201. The jig 230 can be provided with another part of the flow section of the suction passage 201. The pickup module 200 further comprises a connector 250 connected to the end of the connecting shaft 220 away from the jig 230, and the connector 250 is connected to the negative pressure generator to form negative pressure in the connecting shaft 220 and the jig 230.
[0045] Please refer to Figure 4 In one embodiment, the pickup module 200 further comprises a bearing 240. The mounting plate 110 is provided with a through hole 113 that connects the first side 111 and the second side 112. The inner ring of the bearing 240 is connected to the connecting shaft 220 and is sleeved on the outside of the connecting shaft 220, and the outer ring of the bearing 240 is clamped with the hole wall of the through hole 113. That is, the connecting shaft 220 is rotationally connected with the mounting plate 110 through the bearing 240.
[0046] Please refer to Figure 2 and Figure 4 In one embodiment, the driven member 210 rotates to drive the jig 230 to rotate around the first axis O1. The first axis O1 can be the central axis of the connecting shaft 220.
[0047] Please refer to Figure 2 and Figure 4 In one embodiment, the support structure 100 comprises a load beam 101 and a bracket 102, and the two ends of the load beam 101 are rotationally connected with the bracket 102 around the second axis O2. The load beam 101 comprises a cover 120, a side plate 130 and a mounting plate 110 as described in various embodiments, the side plate 130 is arranged on the first side 111 and located on both sides of the mounting plate 110, and the side plate 130 is used to rotationally connect the bracket 102. The cover 120 is arranged on the first side 111. The components of the carrying device 11 located on the first side 111 can be arranged in the cover 120, such as the driving structure 300, and the cover 120 can provide a shielding effect for the driving structure 300 to reduce the risk of the surrounding environment affecting the stable transmission between the driving member 310 and the driven member 210.
[0048] Please refer to Figure 2In one embodiment, the first axis O1 and the second axis O2 are spatially intersected. That is, the workpiece can not only rotate with the jig 230 around the first axis O1, but also the pickup module 200 as a whole can rotate with the load beam 101 around the second axis O2. Since the second axis O2 intersects the first axis O1, rotating around the two different axes can enrich the posture of the workpiece in the detection range, making the detection more sufficient. Further, the first axis O1 and the second axis O2 can be perpendicular to each other.
[0049] Please refer to Figure 6 and Figure 7 In one embodiment, the bearing device 11 further comprises a rotating driver 500, which is arranged on the load beam 101 and is in rotating connection with the support 102 to drive the load beam 101 to rotate relative to the support 102 around the second axis O2. Further, the rotating driver 500 can be located in the housing 120.
[0050] Please continue to refer to Figure 4 In one embodiment, the first side 111 is recessed toward the second side 112 to form a receiving groove 114. The support structure 100 comprises a guide rail 115 arranged in the receiving groove 114. The driving member 310 is in sliding fit with the guide rail 115, and has more stable movement under the guidance and limiting action of the guide rail 115. In this embodiment, compared with directly arranging the guide rail 115 on the first side 111, arranging the guide rail 115 in the receiving groove 114 can make the driving member 310 closer to the first side 111. It can be understood that, since the driving member 310 is in meshing transmission with the driven member 210, the height of the driving member 310 relative to the first side 111 is substantially the same as that of the driven member 210. Therefore, arranging the guide rail 115 in the receiving groove 114 can shorten the distance between the driven member 210 and the mounting plate 110, so that the mounting plate 110 can more fully support the driven member 210 through the connecting shaft 220, improving the stability of transmission. At the same time, such arrangement can also make the overall structure of the bearing device 11 more compact.
[0051] Please refer to Figures 6 to 8 In one embodiment, the support structure 100 further comprises a mounting bracket 140 arranged on the first side 111. The first driver 320 is arranged on the mounting bracket 140 to be fixed relative to the mounting plate 110. The driving structure 300 further comprises a connecting member 330, and the first driver 320 is connected with the connecting member 330 for driving the connecting member 330 to move along the reference direction K. The connecting member 330 is in transmission connection with the driving member 310, so that when the connecting member 330 moves along the reference direction K, the driving member 310 can be driven to move along the reference direction K together, thereby driving the pickup module 200 to rotate.
[0052] The driving structure 300 further comprises a trigger piece 340 and a plurality of sensors 350, which are arranged on the mounting frame 140 along the reference direction K and electrically connected to the first driver 320. The trigger piece 340 is arranged on the connecting piece 330 and triggers the sensors 350 when passing by any sensor 350. The sensors 350 can be arranged at positions corresponding to preset angle positions of the jig 230. For example, the trigger piece 340 triggers the sensors 350 to stop the first driver 320, so that the jig 230 stops at a preset angle position for inspection. The number and positions of the sensors 350 along the reference direction K can be designed according to the number and positions of the angle positions of the workpiece for inspection. For example, the number of the sensors 350 can be 2, 3, 4, 5, or 6.
[0053] Further, the detection device 10 further comprises a controller (not shown), and the sensors 350 are connected to the first driver 320 through the controller. When triggered, the sensors 350 can send a stop signal to the controller, and the controller controls the first driver 320 to stop driving after receiving the stop signal. Of course, the above embodiment is only an example of the relationship between the triggering of the sensors 350 and the starting and stopping of the first driver 320. Other control relationships between the sensors 350 and the first driver 320 can also be set according to actual needs.
[0054] Please refer to Figure 8 , and Figure 6 and Figure 7 In one embodiment, the output shaft of the first driver 320 can be configured as a screw rod, one end of the connecting piece 330 is configured as a nut and is sleeved on the output shaft of the first driver 320, and the other end is connected to the driving piece 310. In this way, the output shaft can drive the connecting piece 330 to move along the reference direction K when rotating, so as to drive the driving piece 310 to move along the reference direction K. Of course, the first driver 320 can also be configured to drive the connecting piece 330 to move along the reference direction K in other ways.
[0055] Please refer to Figure 7 and Figure 8 In one embodiment, the sensors 350 are adjustably arranged on the mounting frame 140, so that the carrying device 11 can be adapted to workpieces with different detection requirements. That is, the positions of the sensors 350 on the mounting frame 140 can be adjusted to adapt the carrying device 11 to workpieces with different angle positions for inspection.
[0056] Further, the mounting rack 140 comprises upright plates 150 and a supporting plate 160. The upright plates 150 are connected to the supporting plate 160 at one end and connected to the first side 111 of the mounting plate 110 at the other end. The supporting plate 160 is provided with a positioning track 170, and the sensor 350 is adjustably arranged on the positioning track 170.
[0057] Please refer to Figure 9 and Figure 10 , and in combination with Figure 2 and Figure 3 In one embodiment, the positioning structure 400 comprises a positioning member 410, which is capable of positioning the workpiece together with the reference part 231. The positioning member 410 is movably arranged on the mounting plate 110 along the positioning direction M to approach and move away from the jig 230. The positioning member 410 comprises a first abutting surface 410a and a second abutting surface 410b, both of which are used to contact the workpiece. The first abutting surface 410a and the second abutting surface 410b intersect to form a first positioning angle 410c. The reference part 231 is configured to comprise a first baffle plate 232 and a second baffle plate 233. The extension direction of the first baffle plate 232 intersects the extension direction of the second baffle plate 233 to form a second positioning angle 230a. In addition, the jig 230 is capable of rotating to a to-be-positioned angle position. When the jig 230 is in the to-be-positioned angle position, the second positioning angle 230a is oppositely arranged with the first positioning angle 410c. Thus, when the positioning member 410 moves along the positioning direction M, the first positioning angle 410c can push the workpiece located on the jig 230 to a position where the second positioning angle 230a is contacted to position the workpiece. Since the two abutting surfaces forming the first positioning angle 410c intersect, and the first baffle plate 232 and the second baffle plate 233 forming the second positioning angle 230a also intersect, the workpiece can be completely positioned under the clamping of the first positioning angle 410c and the second positioning angle 230a.
[0058] In the conventional technology, the structure with positioning function usually comprises two positioning parts, which are oppositely arranged with the first baffle plate 232 and the second baffle plate 233 respectively. When the two positioning parts are driven to move along different directions to the first baffle plate 232 and the second baffle plate 233 respectively, the workpiece can be pushed to contact the first baffle plate 232 and the second baffle plate 233 at the same time to realize the positioning of the workpiece. In the present embodiment, the positioning member 410 is configured to comprise two intersecting first abutting surface 410a and second abutting surface 410b. The first positioning angle 410c formed by the two abutting surfaces can push the workpiece to contact the first baffle plate 232 and the second baffle plate 233 at the same time, which simplifies the structure of the carrying device 11.
[0059] Please refer to Figure 9In one embodiment, the first abutting surface 410a can be arranged opposite to the first baffle 232, and the second abutting surface 410b can be arranged opposite to the second baffle 233. Thus, during the pushing of the workpiece by the positioning member 410, the first abutting surface 410a can apply a pushing force to the workpiece towards the first baffle 232, and the second abutting surface 410b can apply a pushing force to the workpiece towards the second baffle 233, and the directions of the two pushing forces are different, so that the workpiece is positioned.
[0060] Referring to Figure 9 In one embodiment, an angle bisector of the first positioning angle 410c formed by the positioning member 410 coincides with the positioning direction M, that is, the angle between the positioning direction M and the first abutting surface 410a is equal to the angle between the positioning direction M and the second abutting surface 410b. Further, the reference portion 231 and the positioning member 410 that cooperate to position the same workpiece are referred to as the same positioning group. For the same positioning group, the positioning direction M of the positioning member 410 coincides with the angle bisector of the second positioning angle 230a formed by the first baffle 232 and the second baffle 233. That is, the positioning direction M of the positioning member 410 coincides with the angle bisector of the second positioning angle 230a formed by the reference portion 231.
[0061] Further, the first baffle 232 can be arranged to extend along the first direction S1, and the second baffle 233 can be arranged to extend along the second direction S2. The above-mentioned positioning direction M coinciding with the angle bisector of the second positioning angle 230a means that the angle between the positioning direction M and the first direction S1 is equal to the angle between the positioning direction M and the second direction S2.
[0062] Further, the positioning direction M intersects the reference direction K, that is, the positioning direction M does not move along the distribution direction of the jig 230, which reduces the occupation of the distribution space of the jig 230, and facilitates the more compact arrangement of multiple pick-up modules 200. In addition, the positioning direction M can be inclined relative to the reference direction K to make full use of the limited mounting arrangement space on the mounting plate 110.
[0063] Further, the first direction S1 is perpendicular to the second direction S2, and at this time, the angle between the positioning direction M and the first direction S1 and the angle between the positioning direction M and the second direction S2 are both 45°. When the jig 230 is at the angle position to be positioned, the first direction S1 can be parallel to the reference direction K.
[0064] Referring to Figure 9In one embodiment, the positioning structure 400 comprises a second driver 420 and a support plate 430, and a plurality of positioning members 410 are arranged on the support plate 430 and correspond to the plurality of jigs 230 one by one. The second driver 420 is connected with the support plate 430 to drive the support plate 430 to move along the positioning direction M. Since the positioning members 410 and the jigs 230 of the same positioning group have a determined relative position, the positioning members 410 are synchronously driven to move towards the jigs 230, so that the workpieces on each jig 230 can be positioned in batches, and the positioning efficiency is improved. Further, the extension direction of the support plate 430 is parallel to the reference direction K. The number of the second driver 420 can be two, and the two second drivers 420 are arranged on the second side 112. The two ends of the support plate 430 are respectively connected with the two first drivers 320, and the two second drivers 420 synchronously drive the support plate 430, so that the support plate 430 maintains the posture parallel to the reference direction K during the movement, and the movement consistency of each positioning member 410 relative to the corresponding jig 230 is high, and the batch positioning effect is good. The second side 112 of the mounting plate 110 is also provided with a slide rail (not shown in the figure, the same below), which extends along the positioning direction M, and the support plate 430 is in sliding fit with the slide rail.
[0065] Please continue to refer to Figure 9 In one embodiment, the support plate 430 is provided with a plurality of sliding grooves 431, and the sliding grooves 431 extend along the positioning direction M. The plurality of positioning members 410 are arranged in the plurality of sliding grooves 431 one by one, and the positions of the positioning members 410 in the sliding grooves 431 are adjustable. In this way, the positions of the positioning members 410 in the sliding grooves 431 are adjusted, so that the positioning members 410 can position the workpieces of different sizes on the jigs 230, and the versatility of the positioning structure 400 is improved.
[0066] Please refer to Figure 10In one embodiment, the positioning member 410 comprises a connecting plate 411, a pushing block 412 and an elastic member 413, the elastic member 413 is arranged on the connecting plate 411. The pushing block 412 is arranged movably on the connecting plate 411 and is used to contact and push the workpiece. The connecting plate 411 is provided with a limiting groove 411a, the limiting groove 411a is provided with a guide hole 411b which is in communication with the outside and is arranged on the side of the jig 230, the guide hole 411b extends along the positioning direction M. The pushing block 412 comprises a matching part 412a and a positioning part 412b which are connected with each other, the matching part 412a is arranged movably in the limiting groove 411a, and the opposite two side walls of the limiting groove 411a in the positioning direction M are used to abut against the matching part 412a. The positioning part 412b extends to the outside of the limiting groove 411a through the guide hole 411b, so as to push the workpiece. The elastic member 413 is arranged in the limiting groove 411a and elastically abuts between the side wall of the limiting groove 411a which is away from the guide hole 411b and the matching part 412a. In this way, the pushing movement of the pushing block 412 has the elastic characteristic, so as to reduce the probability that the workpiece and the reference part 231 are stuck to cause the positioning member 410 to directly crush the workpiece.
[0067] Further, the elastic member 413 can be configured as a compression spring.
[0068] Further, the connecting plate 411 is further provided with a cover plate 411c, the cover plate 411c can close the limiting groove 411a, so that the matching part 412a moves stably in the limiting groove 411a.
[0069] Please continue to refer to Figure 10 In one embodiment, the side of the positioning member 410 which faces the jig 230 can be configured to be provided with a positioning groove 412c, so as to obliquely push the workpiece to contact the reference part 231. Further, the positioning groove 412c can be arranged on the side of the positioning part 412b of the pushing block 412 which faces the jig 230.
[0070] Please continue to refer to Figure 10 In one embodiment, the first abutting surface 410a and the second abutting surface 410b can be configured as the groove wall surface of the positioning groove 412c.
