Description

Technical Field

[0001] The present invention relates to the field of workpiece measurement, and particularly to a workpiece size measurement device based on a high-speed camera. Background Art

[0002] In the production processes of lamp fittings, electronic product fittings, etc., in order to ensure product quality, size measurement and inspection are indispensable links. Currently, industrial cameras are generally used as the core tools for identification and inspection in the industrial field. The implementation method of this technology is mainly as follows: the workpiece moves continuously on the assembly line, while the high-speed camera is fixedly installed at a certain position to take pictures and measure the size of the passing workpiece.

[0003] However, the existing detection methods require the high-speed camera to have extremely high shutter speed and frame rate to cope with the high-speed movement of the workpiece. If the movement speed of the workpiece is too fast and the camera shooting speed cannot match, it may lead to measurement errors. Moreover, the detection process requires continuous feeding at one end of the assembly line. Manual feeding is not only time-consuming and laborious, but also difficult to guarantee the placement accuracy of the workpiece. Although robotic feeding can improve the accuracy, it is costly and requires regular maintenance, which is difficult to meet the enterprise's needs.

[0049] Further, as Figure 7 , Figures 9 - 12As shown, the multifunctional turntable 5 is provided with a squaring assembly linked with the linkage member, and the squaring assembly includes a second accommodating groove 30 which is arranged on the side wall of the inner cavity of the first accommodating groove 28 and is annular, and the second accommodating groove 30 is rotatably provided with an annular driving plate 32, and the driving plate 32 is evenly surrounded with an arc-shaped third guide groove 34, and the bottom of the outer periphery of the inner cavity of the groove 18 is provided with a second guide groove 31 which corresponds to the third guide groove 34 one by one, and the inner side of the second guide groove 31 is movably connected with a centering pin 35 along the radial direction of the groove 18, and the lower end of the centering pin 35 is movably guided and matched with the third guide groove 34, and the upper end of the centering pin 35 is used to push the workpiece to move, and a traction pin 21 is provided at one end of the bottom of the driving plate 32, and the bottom of the multifunctional turntable 5 is provided with a traction pin 21 which corresponds to the traction pin 21 one by one.

[0050] like Figures 1 - 3 , Figure 16 As shown, a second driving source 7 corresponding to the guide plate 39 is arranged on the side of the frame 1. The second driving source 7 is preferably a cylinder or a hydraulic cylinder. A material guide slide 4 driven to rise and fall by the second driving source 7 is arranged on the top of the second driving source 7. The material guide slide 4 is a double-layer arrangement, and one end of the material guide slide 4 is convenient for corresponding and adapting to the multi-functional turntable 5. The ends of the two layers of material guide slides 4 away from the multi-functional turntable 5 have different directions.

[0051] It should be noted that a first locking disc 45 is provided at the bottom of the fourth gear 42. An outer periphery of the first locking disc 45 is provided with first locking grooves 53 which are in one-to-one correspondence with the grooves 18 and are arc-shaped.

When the first incomplete gear 43 is separated from the fourth gear 42, the locking arc 46 will enter one of the first locking grooves 53 on the side of the first locking disc 45 to ensure the stability of the multi-functional turntable 5. When the first incomplete gear 43 is separated from the fifth gear 44, the locking arc 46 will enter the second locking groove 54 to ensure the stability of the first vertical shaft 11.

[0052] During use, place the workpiece into the barrel 9 at the top of the barrel 9. Control the first drive source 6 to drive the first incomplete gear 43 to rotate. When the first incomplete gear 43 meshes with the fourth gear 42, it can drive the multi-functional turntable 5 to rotate by a certain amplitude. When it meshes with the fifth gear 44, it can drive the fifth gear 44 to rotate one week. As a result, the second incomplete gear 47 is driven by the fifth gear 44 to rotate one week. When the second incomplete gear 47 rotates one week, it can drive the first traction frame 36 and the rack 48 to reciprocate once. Furthermore, the first gear 13 drives the second gear 14 to reciprocate and rotate once through the second vertical shaft 12. Furthermore, the gear ring 16 drives the first vertical shaft 11 to rotate through the third gear 15. The first vertical shaft 11 drives the two sets of supporting plates 17 on its side wall to swing reciprocally and alternately enter and exit the barrel 9. When entering, it can support the workpiece, and when exiting, it can lower the workpiece onto the supporting plate 17 that has just entered at the bottom. In this way, it reciprocates for a certain period of time until the workpiece reaches the groove 18 below the barrel 9. Then the worker stops feeding from the top of the barrel 9. The height of the barrel 9 and the number of supporting plates 17 can be designed according to the measurement quantity each time, or it can be supplemented after measuring a certain quantity of workpieces, without continuously occupying manual labor. Subsequently, the first drive source 6 continues to operate. The groove 18 with the workpiece displaces in the direction of the push plate 38 during the meshing of the first incomplete gear 43 and the fourth gear 42. When the traction pin 21 corresponds to the push plate 38, the first incomplete gear 43 separates from the fourth gear 42 and then meshes with the fifth gear 44. The automatic feeding mechanism continues to feed. During this period, the multi-functional turntable 5 does not move. Since the first traction frame 36 will drive the second traction frame 37 to reciprocate once during feeding, the second traction frame 37 drives the driving arm 41 and the driving pin 52 to displace as a whole. Under the action of the fourth guiding groove 51, the sliding plate 8 moves outwards. One of the sliding plates 8 drives the push plate 38 to move outwards. The push plate 38 pushes the traction pin 21 to displace in the first guiding groove 26, and the third elastic member 33 is compressed. Furthermore, the driving plate 32 is driven to rotate. Under the action of the third guiding groove 34 and the second guiding groove 31, the centering pin 35 displaces radially along the groove 18 to center the offset workpiece. Then the sliding plate 8 resets, the third elastic member 33 resets, and the centering pin 35 resets and moves outwards. Then the first incomplete gear 43 separates from the fifth gear 44 and meshes with the fourth gear 42. The multi-functional turntable 5 continues to rotate. The centered workpiece displaces towards the high-speed camera 3. After reaching, the first incomplete gear 43 separates from the fourth gear 42 again and meshes with the fifth gear 44. During this period, feeding, centering, and measuring work are carried out. As the equipment operates, the measured workpieces gradually move towards the sliding plate 8 corresponding to the guiding plate 39. After reaching, the first incomplete gear 43 will also separate from the fourth gear 42 and mesh with the fifth gear 44. The same as the centering principle, the guiding plate 39 and the push rod 40 will be driven by the sliding plate 8 on one side to move outwards. Under the action of the guiding plate 39, the roller 24 displaces to the top of the guiding plate 39, and the lifting frame 23 drives the lifting plate 20 to rise, and the second elastic member 29 is compressed.The lifting plate 20 lifts the measured workpiece to the top of the multi-functional turntable 5 and corresponds to the pushing plate 19. Subsequently, the push rod 40 contacts the side wall at the lower end of the traction plate 25. The push rod 40 pushes the traction plate 25 to move outward. The traction plate 25 drives the pushing plate 19 to move outward, and the first elastic member 27 is compressed. The pushing plate 19 pushes the workpiece on the top of the lifting plate 20 outward. And according to whether the workpiece is qualified after measurement, the corresponding material guiding chute 4 is selected to correspond to the workpiece. The two-layer material guiding chute 4 is controlled by the second driving source 7 to lift and lower. One layer is used to discharge qualified workpieces, and the other layer is used to discharge unqualified workpieces. After the material guiding chute 4 corresponds to the workpiece, the pushing plate 19 can push the workpiece into the corresponding material guiding chute 4. After that, the first incomplete gear 43 continues to disengage from the fifth gear 44 and engages with the fourth gear 42, and the multi-functional turntable 5 continues to rotate, and so on in a cycle. The whole process can store the workpieces to be measured in the material cylinder 9 without frequent manual participation. And when loading, the high-speed camera 3 on the other side measures, and at the same time, the centering assembly centers the workpiece after loading, and the unloading assembly unloads the measured workpiece. The equipment has high linkage, compact structure, low cost, and is convenient for maintenance. Only through a set of gear and rack group and the specially designed multi-functional turntable 5 can continuous measurement operations be realized, increasing the practicability.
