[0034] See also Figure 1 , Figure 1A side view of a detection device provided in one embodiment of the present application is shown. The detection device 10 provided in one embodiment of the present application is used to perform appearance detection and size measurement on a workpiece. The detection device 10 includes a carrying device 11 and a detection module 12, the carrying device 11 is used to pick up the workpiece, and the detection module 12 is used to perform appearance detection and size measurement on the workpiece. The number of the carrying devices 11 can be one or more.

[0035] Please continue reading Figure 1 In one embodiment, the detection device 10 further includes a driving platform 13 , which is connected to the carrying device 11 to drive a single or multiple carrying devices 11 to move into the detection range of the detection module 12 .

[0036] See also Figures 2 to 4 The carrying device 11 provided in one embodiment of the present application includes a supporting structure 100, a picking module 200, a driving structure 300 and a positioning structure 400, and the picking module 200, the driving structure 300 and the positioning structure 400 are all arranged on the supporting structure 100. The supporting structure 100 includes a mounting plate 110, and the mounting plate 110 has a first side 111 and a second side 112 arranged opposite to each other. 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 fixture 230. The connecting shaft 220 is rotatably penetrated in the mounting plate 110, and one end of the connecting shaft 220 is located on the first side 111 and is transmission-connected to the driven member 210. The other end of the connecting shaft 220 is located on the second side 112 and is transmission-connected to the fixture 230. Transmission teeth are arranged on the periphery of the driven member 210. The driving structure 300 includes a movable active member 310, which is also provided with transmission teeth. The active member 310 and the driven member 210 are meshed with each other through the transmission teeth to drive the driven member 210 to rotate. The fixture 230 is used to pick up the workpiece, and the fixture 230 is provided with a reference portion 231. The positioning structure 400 is used to push the workpiece located on the fixture 230 to a position contacting the reference portion 231 to position the workpiece.

[0037] In the above-mentioned carrying device 11, the mounting plate 110 has a first side 111 and a second side 112 arranged opposite to each other. The driving structure 300 is arranged on the first side 111 and is transmission-connected to the driven member 210, so that the driving structure 300 can drive the picking module 200 to rotate. The positioning structure 400 is arranged on the second side 112, and the positioning structure 400 can position the workpiece on the fixture 230 so that the workpiece is in the expected position. Since the driving structure 300 and the positioning structure 400 with movement capabilities are respectively located on opposite sides of the mounting plate 110, the movements of the two will not interfere with each other. Therefore, the carrying device 11 does not need to be configured to have a larger structural size in order to coordinate the movement range of the two. In short, such a setting can make the carrying device 11 have a smaller structural size, more flexible movement, and convenient for carrying workpieces. It should be noted that, since the connecting shaft 220 passes through the mounting plate 110 and the two ends of the connecting shaft 220 are respectively located on the first side 111 and the second side 112, the connecting shaft 220 can transmit and connect the follower 210 located on the first side 111 and the fixture 230 located on the second side 112 together, so that the picking module 200 moves as a whole.

[0038] Furthermore, in conventional technology, a transmission method such as belt drive that uses friction for transmission is usually used to drive the jig 230 to move. Since the transmission method is not tightly matched, under the action of inertia, relative movement between the jig 230 and the transmission belt is likely to occur when starting and stopping, resulting in uncertainty in the position of the jig 230. Since the jig 230 is used to pick up workpieces, the position of the jig 230 corresponds to the position of the workpiece. For detection and measurement, when the workpiece cannot accurately move to the expected position, the workpiece cannot be fully exposed to the detection range of the detection module 12, making the detection insufficient and prone to false alarms of defective products. Compared with the transmission method such as belt drive that uses friction for transmission in conventional technology, the present application uses the method of transmission tooth meshing to achieve transmission, and the transmission teeth are more tightly matched and not easy to loosen. Such a setting can improve the motion accuracy and position accuracy of the jig 230 and the workpiece picked up by the jig 230, make the detection more accurate, and reduce the false alarm rate of defective products.

[0039] See also Figure 5In one embodiment, the transmission method between the driven member 210 and the active member 310 may include but is not limited to gear rack transmission, worm gear transmission and bevel gear transmission. Further, the driven member 210 may be constructed as a gear, and the active member 310 may be constructed as a rack that meshes with the driven member 210. The relevant parameters of the gear and the rack can be adjusted so that the active member 310 and the driven member 210 have a reverse self-locking characteristic when transmitting, that is, the active member 310 can drive the driven member 210 to rotate, and the driven member 210 cannot reversely drive the active member 310 to move, so as to further improve the position stability and accuracy of the fixture 230. For example, the tooth profile angle of the transmission teeth can be adjusted, the module of the gear and the rack can be reduced, the materials with a large friction coefficient can be selected for the gear and the rack, or the tooth surface of the transmission teeth can be surface treated, and the transmission ratio between the gear and the rack can be adjusted. When the fixture 230 is not required to rotate a full circle, the transmission teeth may be distributed only in a partial area of ​​the outer circumference of the driven member 210 , that is, the driven member 210 is an incomplete gear at this time.

[0040] See also Figure 4 In one embodiment, the driving structure 300 further includes a first driver 320, and the first driver 320 is connected to the active member 310 to drive the active member 310 to move. Furthermore, the first driver 320 can also be configured to have a self-locking characteristic.

[0041] See also Figure 5 In one embodiment, the carrier device 11 includes a plurality of pickup modules 200, and the plurality of pickup modules 200 are spaced apart along the reference direction K. The active member 310 is simultaneously meshed with the driven members 210 of the plurality of pickup modules 200 for transmission. In combination with the above, the active member 310 is configured as a rack so that it can be conveniently meshed with the driven members 210 of the plurality of pickup modules 200 for transmission at the same time.

[0042] In one embodiment, the transmission teeth may be configured as helical teeth, that is, the driven member 210 is a helical gear and the driving member 310 is a helical rack, so as to have a higher reduction ratio and facilitate driving multiple driven members 210 to rotate simultaneously.

[0043] In one embodiment, the picking module 200 can be configured to pick up the workpiece by vacuum adsorption, so as to pick up workpieces of various shapes. Since the carrying device 11 includes the positioning structure 400, the picking module 200 picks up the workpiece by vacuum adsorption, and the workpiece can also be positioned by the positioning structure 400 and stably in the expected position. Figure 4Furthermore, a suction channel 201 is provided in the pickup module 200, one end of the suction channel 201 is used to connect to the negative pressure generator, and the other end of the suction channel 201 forms a suction hole 230b on the end surface of the fixture 230 that is away from the follower 210. The reference portion 231 is provided on the circumferential outer side of the area where the suction hole 230b is located. The reference portion 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 be blocked by the workpiece and adsorb the workpiece.

[0044] Please continue reading Figure 4 In one embodiment, the connecting shaft 220 may be configured as a hollow setting to form a partial flow section of the adsorption channel 201. Another partial flow section of the adsorption channel 201 may be opened in the fixture 230. The picking module 200 further includes a joint 250, which is connected to an end of the connecting shaft 220 away from the fixture 230, and the joint 250 is used to communicate with the negative pressure generator so as to form negative pressure in the connecting shaft 220 and the fixture 230.

[0045] See also Figure 4 In one embodiment, the pickup module 200 further includes a bearing 240. The mounting plate 110 is provided with a through hole 113, and the through hole 113 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 sleeved outside the connecting shaft 220, and the outer ring of the bearing 240 is engaged with the hole wall of the through hole 113. In other words, the connecting shaft 220 is rotatably matched with the mounting plate 110 through the bearing 240.

[0046] See also Figure 2 and Figure 4 In one embodiment, the driven member 210 is used to drive the fixture 230 to rotate around the first axis O1 when rotating. The first axis O1 may be the central axis of the connecting shaft 220.

[0047] See also Figure 2 and Figure 4 In one embodiment, the support structure 100 includes a carrier beam 101 and a bracket 102, and both ends of the carrier beam 101 are rotatably connected to the bracket 102 around a second axis O2. The carrier beam 101 includes a cover 120, a side plate 130 and a mounting plate 110 as described in each embodiment, the side plate 130 is provided on the first side 111 and located on both sides of the mounting plate 110, and the side plate 130 is used to rotatably connect the bracket 102. The cover 120 is provided on the first side 111. The components of the carrier device 11 located on the first side 111 can all be provided in the cover 120, such as the drive structure 300, and the cover 120 can provide a containment effect for the drive structure 300 to reduce the risk of the surrounding environment affecting the stable transmission between the active member 310 and the driven member 210.

[0048] See also Figure 2In one embodiment, the first axis O1 and the second axis O2 intersect in space. That is, the workpiece can not only rotate around the first axis O1 with the fixture 230, but the picking module 200 as a whole can also rotate around the second axis O2 with the carrier beam 101. Since the second axis O2 intersects with the first axis O1, rotating around two different axes can enrich the posture of the workpiece within the detection range, making the detection more complete. Furthermore, the first axis O1 and the second axis O2 can be perpendicular to each other.

[0049] See also Figure 6 and Figure 7 In one embodiment, the carrier 11 further includes a rotation driver 500, which is disposed on the carrier beam 101 and is rotationally connected to the bracket 102 to drive the carrier beam 101 to rotate relative to the bracket 102 around the second axis O2. Further, the rotation driver 500 may be located in the housing 120.

[0050] Please continue reading 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 includes a guide rail 115, which is disposed in the receiving groove 114. The active member 310 is slidably matched with the guide rail 115, and the guide rail 115 is transplanted to have a more stable movement under the guiding and limiting effects. 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 active member 310 closer to the first side 111. It can be understood that since the active member 310 and the driven member 210 are meshed and transmitted, the heights of the two are substantially the same relative to the first side 111. 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, and the mounting plate 110 can more fully support the driven member 210 through the connecting shaft 220, thereby improving the stability of the transmission. At the same time, such an arrangement can also make the overall structure of the carrying device 11 more compact.

[0051] See also Figures 6 to 8 In one embodiment, the support structure 100 further includes a mounting frame 140, and the mounting frame 140 is disposed on the first side 111. The first driver 320 is disposed on the mounting frame 140 to be fixed relative to the mounting plate 110. The driving structure 300 further includes a connecting member 330, and the first driver 320 is connected to the connecting member 330 to drive the connecting member 330 to move along the reference direction K. The connecting member 330 is in transmission connection with the active member 310, so when the connecting member 330 moves along the reference direction K, it can drive the active member 310 to move along the reference direction K, thereby driving the pickup module 200 to rotate.

[0052] Among them, the driving structure 300 also includes a trigger sheet 340 and a plurality of sensors 350, and the plurality of sensors 350 are arranged at intervals on the mounting frame 140 along the reference direction K, and the sensors 350 are electrically connected to the first driver 320. The trigger sheet 340 is arranged on the connecting member 330, and the trigger sheet 340 triggers the sensor 350 when passing through any sensor 350. The setting position of the sensor 350 can correspond to the preset angle position of the fixture 230. For example, when the trigger sheet 340 triggers the sensor 350, the first driver 320 can stop driving, and the fixture 230 stops rotating and is in a preset angle position to be inspected. The number of sensors 350 and their positions in the reference direction K can be specifically designed according to the number of angles to be inspected and the angle positions to be inspected of the workpiece. For example, the number of sensors 350 can be 2, 3, 4, 5, 6, etc.

[0053] Furthermore, the detection device 10 further includes a controller (not shown in the figure, the same below), the sensor 350 is connected to the first driver 320 through the controller, the sensor 350 can send a stop signal to the controller when triggered, and the controller controls the first driver 320 to stop driving after receiving the stop signal. Of course, this embodiment is only used to illustrate the relationship between the triggering of the sensor 350 and the start and stop of the first driver 320, and other control relationships between the sensor 350 and the first driver 320 can also be set according to actual needs.

[0054] See also Figure 8 , combined with Figure 6 and Figure 7 In one embodiment, the output shaft of the first driver 320 can be configured as a screw, one end of the connecting member 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 active member 310. Therefore, when the output shaft rotates, it can drive the connecting member 330 to move along the reference direction K, so as to drive the active member 310 to move along the reference direction K. Of course, the first driver 320 can also be configured to drive the connecting member 330 to move along the reference direction K in other ways.

[0055] See also Figure 7 and Figure 8 In one embodiment, the position of the sensor 350 is adjustable on the mounting frame 140, so that the carrying device 11 can be adapted to workpieces with different inspection requirements. In other words, the position of the sensor 350 on the mounting frame 140 can be adjusted, so that the carrying device 11 can be adapted to various workpieces with different inspection angle requirements.

[0056] Furthermore, the mounting frame 140 includes a vertical plate 150 and a support plate 160. One end of the vertical plates 150 is connected to the support plate 160, and the other end is connected to the first side 111 of the mounting plate 110. The support plate 160 is provided with a positioning track 170, and the sensor 350 is adjustable on the positioning track 170.

[0057] See also Fig. 9 and Fig.10 , combined with Figure 2 and Figure 3 In one embodiment, the positioning structure 400 includes a positioning member 410, which can cooperate with the reference portion 231 to position the workpiece. The positioning member 410 is movably arranged on the mounting plate 110 along the positioning direction M to approach and move away from the fixture 230. The positioning member 410 includes a first abutting surface 410a and a second abutting surface 410b, both of which are used to contact the workpiece, and the first abutting surface 410a and the second abutting surface 410b intersect to form a first positioning angle 410c. The reference portion 231 is configured to include a first baffle 232 and a second baffle 233, and the extension direction of the first baffle 232 intersects with the extension direction of the second baffle 233 to form a second positioning angle 230a. In addition, the fixture 230 can be rotated to the angle position to be positioned. When the fixture 230 is at the angle position to be positioned, the second positioning angle 230a is arranged opposite to 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 fixture 230 to a position that contacts the second positioning angle 230a, so as to position the workpiece. Since the two contact surfaces forming the first positioning angle 410c intersect, and the first baffle 232 and the second baffle 233 forming the second positioning angle 230a also intersect, the workpiece can be completely positioned under the facing clamping of the first positioning angle 410c and the second positioning angle 230a.

[0058] In conventional technology, a structure with a positioning function is usually configured to include two positioning parts, and the two positioning parts are respectively arranged opposite to the first baffle 232 and the second baffle 233. When the two positioning parts are driven to move toward the first baffle 232 and the second baffle 233 in different directions, the workpiece can be pushed to contact the first baffle 232 and the second baffle 233 at the same time, thereby achieving positioning of the workpiece. In this embodiment, the positioning member 410 is configured to include two intersecting first abutting surfaces 410a and the second abutting surfaces 410b, and the first positioning angle 410c formed by the two abutting surfaces can be used to push the workpiece to contact the first baffle 232 and the second baffle 233 at the same time, thereby simplifying the structure of the carrier 11.

[0059] See also Fig. 9In one embodiment, the first abutting surface 410a can be disposed opposite to the first baffle 232, and the second abutting surface 410b can be disposed opposite to the second baffle 233. Thus, when the positioning member 410 pushes the workpiece, the first abutting surface 410a can apply a thrust force close to the first baffle 232 to the workpiece, and the second abutting surface 410b can apply a thrust force close to the second baffle 233 to the workpiece, and the two thrust forces have different directions, so that the workpiece is positioned.

[0060] See also Fig. 9 In one embodiment, the angular bisector of the first positioning angle 410c formed by the positioning member 410 coincides with the corresponding 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 with each other 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 angular bisector of the second positioning angle 230a formed by the first baffle 232 and the second baffle 233. In other words, the positioning direction M of the positioning member 410 coincides with the angular bisector of the second positioning angle 230a formed by the corresponding 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 positioning direction M coincides with the angular bisector of the second positioning angle 230a, which 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] Furthermore, the positioning direction M intersects with the reference direction K, that is, the positioning direction M does not move along the distribution direction of the fixture 230, which reduces the occupation of the distribution space of the fixture 230 and facilitates a more compact arrangement of multiple picking modules 200. In addition, the positioning direction M can be inclined relative to the reference direction K to make full use of the limited installation and arrangement space on the mounting plate 110.

[0063] Furthermore, the first direction S1 is perpendicular to the second direction S2, and the angles between the positioning direction M and the first direction S1 and the second direction S2 are both 45 degrees. When the fixture 230 is at the angle position to be positioned, the first direction S1 can be parallel to the reference direction K.

[0064] See also Fig. 9In one embodiment, the positioning structure 400 includes a second driver 420 and a supporting plate 430, and a plurality of positioning members 410 are disposed on the supporting plate 430 and correspond one-to-one to a plurality of jigs 230. The second driver 420 is connected to the supporting plate 430 to drive the supporting plate 430 to move along the positioning direction M. Since the positioning members 410 and the jig 230 of the same positioning group have a certain relative position, the positioning members 410 are synchronously driven to move in a direction close to the jig 230, so that the workpieces on each jig 230 can be positioned in batches, thereby improving the positioning efficiency. Furthermore, the extension direction of the supporting plate 430 is parallel to the reference direction K. The number of the second drivers 420 can be two, and the two second drivers 420 are both disposed on the second side 112. The two ends of the support plate 430 are respectively connected to the two first drivers 320, and the two second drivers 420 synchronously drive the support plate 430, so that the support plate 430 maintains a posture parallel to the reference direction K during movement, so that the movement consistency of each positioning member 410 relative to the corresponding fixture 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 slides with the slide rail.

[0065] Please continue reading Fig. 9 In one embodiment, the support plate 430 is provided with a plurality of slide grooves 431, and the slide grooves 431 extend along the positioning direction M. A plurality of positioning members 410 are arranged in a one-to-one correspondence in the plurality of slide grooves 431, and the position of the positioning member 410 in the slide groove 431 is adjustable. Thus, by adjusting the position of the positioning member 410 along the slide groove 431, the positioning member 410 can position workpieces of different sizes on the fixture 230, thereby improving the versatility of the positioning structure 400.

[0066] See also Fig.10In one embodiment, the positioning member 410 includes a connecting plate 411, a push block 412 and an elastic member 413, and the elastic member 413 is disposed on the connecting plate 411. The push block 412 is used to contact and push the workpiece, and the push block 412 is movably disposed on the connecting plate 411. The connecting plate 411 is provided with a limiting groove 411a, and the groove wall of the limiting groove 411a close to the side where the fixture 230 is located is provided with a guide hole 411b connected to the outside, and the guide hole 411b extends along the positioning direction M. The push block 412 includes a matching portion 412a and a positioning portion 412b connected to each other, and the matching portion 412a is movably disposed in the limiting groove 411a, and the groove walls on both sides of the limiting groove 411a facing each other in the positioning direction M are used to abut the matching portion 412a. The positioning portion 412b extends to the outside of the limiting groove 411a through the guide hole 411b to push the workpiece. The elastic member 413 is disposed in the limiting groove 411a, and the elastic member 413 elastically abuts between the groove wall of the limiting groove 411a which is relatively far from the guide hole 411b and the matching portion 412a. This arrangement makes the pushing motion of the push block 412 have elastic characteristics, so as to reduce the probability that the workpiece and the reference portion 231 are stuck and the positioning member 410 directly crushes the workpiece.

[0067] Further, the elastic member 413 may be configured as a compression spring.

[0068] Furthermore, the connecting plate 411 is further provided with a cover plate 411 c, which can close the limiting groove 411 a, so that the matching portion 412 a can stably move in the limiting groove 411 a.

[0069] Please continue reading Fig.10 In one embodiment, the side of the positioning member 410 facing the fixture 230 may be configured to be provided with a positioning groove 412c so as to obliquely push the workpiece to contact the reference portion 231. Further, the positioning groove 412c may be provided on the side of the positioning portion 412b of the push block 412 facing the fixture 230.

[0070] Please continue reading Fig.10 In one embodiment, the first abutting surface 410a and the second abutting surface 410b may be configured as groove wall surfaces of the positioning groove 412c.
