[0036] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1 to 6 In an embodiment of the present invention, a capacitive vision inspection device includes a conveyor belt 1, a material transfer mechanism 2, a detection mechanism 3, and a material receiving tray 4. The detection mechanism 3 is arranged between the material transfer mechanism 2 and the material receiving tray 4, and the conveyor belt 1 is arranged above the material transfer mechanism 2.

[0038] Among them, the material moving mechanism 2 includes a material moving carrier plate 21, a material moving barrel 22 is slidably installed on the top of the material moving carrier plate 21, and a material moving driving assembly 24 is provided at the bottom of the material moving carrier plate 21 for driving the material moving barrel 22 to move along the material moving carrier plate 21. An opening is provided on the side of the material moving barrel 22 close to the detection mechanism 3, and a stopper 23 for closing the opening is hinged on the material moving barrel 22. When the material moving barrel 22 moves in a direction close to the detection mechanism 3, the stopper 23 flips outward to open the opening. When the material moving barrel 22 moves in a direction away from the detection mechanism 3, the stopper 23 flips inward to close the opening.

[0039] The detection mechanism 3 includes a detection supporting plate 31, a turntable 32 is rotatably installed on the top of the detection supporting plate 31, and a plurality of material receiving troughs 33 are provided on the outer periphery of the turntable 32. A rotation driving assembly 34 for driving the turntable 32 to rotate is provided at the bottom of the detection supporting plate 31. A mounting frame is provided on the top of the detection supporting plate 31 on one side of the turntable 32. The mounting frame consists of a first vertical plate 35, a second vertical plate 36 and a horizontal plate 37. A first camera 38 is vertically arranged on the top of the horizontal plate 37, and a second camera 39 is horizontally arranged on the side of the first vertical plate 35. A background plate 310 is provided on the second vertical plate 36, and the second camera 39 is facing the background plate 310. A pushing assembly 311 is also provided on the top of the detection supporting plate 31.

[0040] The conveyor belt 1 of the present invention is connected with the capacitor production line. The capacitors produced by the capacitor production line fall into the material transfer barrel 22 through the conveyor belt 1. When the material transfer barrel 22 moves along the material transfer carrier plate 21 under the drive of the material transfer drive component 24, the block 23 flips outward to open the opening. The capacitors in the material transfer barrel 22 can be moved out of the opening to the material transfer carrier plate 21, and then enter the material receiving trough 33 through the material transfer carrier plate 21. Then, the turntable 32 drives the capacitors in the material receiving trough 33 to move to the bottom of the first camera 38 under the drive of the rotation drive component 34, and is placed under the second camera 38. 9 and the background plate 310, the first camera 38 and the second camera 39 collect images of the sides and top of the capacitor, and compare the collected images with the preset template information to determine whether the shapes of the sides and top of the capacitor meet the preset requirements, thereby realizing automatic detection of the capacitor and achieving the purpose of effectively detecting the capacitor at different angles, thereby improving the detection accuracy and detection efficiency of the capacitor. The capacitor that has passed the visual inspection is moved to the receiving tray 4 by the turntable 32, and the pushing component 311 pushes the capacitor that meets the preset requirements into the receiving tray 4.

[0041] The material transfer drive assembly 24 includes a first drive motor 25, a first driving wheel 26, a first driven wheel 27, a first transmission belt 28, a sliding block 29 and a clamping block 210. The first driving wheel 26 and the first driven wheel 27 are arranged at intervals along the length direction of the material transfer carrier plate 21. The rotating shaft of the first drive motor 25 is coaxially connected to the first driving wheel 26. The sliding block 29 is slidably installed at the bottom of the material transfer carrier plate 21 and is located between the first driving wheel 26 and the first driven wheel 27. The first transmission belt 28 is sleeved outside the first driving wheel 26 and the first driven wheel 27. The clamping block 210 is arranged at the bottom of the sliding block 29 and clamped on the first transmission belt 28. The material transfer carrier plate 21 is provided with a through groove 211 running through its top and bottom. The bottom of the material transfer cylinder 22 is connected to the sliding block 29 through the through groove 211. In this way, the first drive motor 25 starts to operate, and under the transmission of the first active wheel 26, the first driven wheel 27 and the first transmission belt 28, drives the sliding block 29 to move back and forth along the material moving support plate 21, thereby driving the material moving barrel 22 to move back and forth along the material moving support plate 21 to push the capacitors on the material moving support plate 21 one by one into the material receiving trough 33.

[0042] Two baffles 11 are spaced apart at the top of the conveyor belt 1. The ends of both baffles 11 extend from the output end of the conveyor belt 1. A discharge frame 12 is provided at the bottom of the ends of the two baffles 11. The discharge frame 12 is located above the material transfer carrier 21. The two baffles 11 prevent the capacitors from falling off the conveyor belt 1, and the discharge frame 12 allows the capacitors on the conveyor belt 1 to fall accurately into the material transfer barrel 22.

[0043] There are two blocks 23, which are hinged on both sides of the material transfer barrel 22 respectively. The lower ends of the two blocks are provided with guide wheel shafts 214, and guide wheels 212 are rotatably installed on the two guide wheel shafts 214. Guide surfaces 213 are provided on both sides of the starting end of the material transfer supporting plate 21. From the starting end to the end of the material transfer supporting plate 21, the guide surface 213 gradually tilts outward. A tension spring 215 is connected between the two guide wheel shafts 214. Under the action of the tension spring 215, the guide wheel 212 always rolls with the guide surface. When the material transfer barrel 22 moves toward the direction approaching the detection mechanism 3, the two guide wheels 212 respectively roll with the guide surfaces 213 on both sides of the material transfer supporting plate 21, so that the two guide wheels 212 move away from each other, thereby causing the block 23 to flip outward to open the opening; under the action of the tension spring 215, the two guide wheels 212 tend to move toward each other, so that when the material transfer barrel 22 moves toward the direction away from the detection mechanism 3, the two guide wheels 212 always roll with the guide surfaces 213 on both sides of the material transfer supporting plate 21, thereby causing the block 23 to flip inward to close the opening to receive the capacitor dropped from the discharge frame 12.

[0044] The mounting frame also includes a support plate 312 and a top plate 357. The first vertical plate 35 is detachably mounted on one side of the support plate 312. An adjustment screw 313 is rotatably mounted on the horizontal plate 37. A screw hole for threaded engagement with the adjustment screw 313 is defined at the top of the support plate 312. The horizontal plate 37 is provided with a through hole 314 extending from the top and bottom thereof. The top plate 357 is vertically positioned within the through hole 314. The first camera 38 is detachably mounted on the upper end of the top plate 357. A light source 315 is detachably mounted on the lower end of the top plate 357. During use, the first vertical plate 35 can be removed, and the height of the horizontal plate 37 can be adjusted by rotating the adjustment screw 313, thereby adjusting the heights of the first and second cameras 38 and 39. This improves practicality. The provision of the light source 315 also increases illumination, ensuring detection accuracy. Furthermore, the light source 315 and the first camera 38 are detachable, making replacement and adjustment of their mounting positions easy.

[0045] The detection mechanism 3 also includes a defective product box 358, which is arranged on one side of the detection carrier plate 31. The pushing assembly 311 includes a support rod 316, which is arranged on the top of the detection carrier plate 31 and on one side of the turntable 32. A support block 359 is provided on the support rod 316, and a good product pushing cylinder 317 is provided on one side of the support block 359. The output end of the good product pushing cylinder 317 faces the receiving tray 4. A pushing plate 318 is provided on the piston rod of the good product pushing cylinder 317. A mounting plate 319 is vertically provided on the other side of the support block 359. A defective product pushing cylinder 320 is provided at the lower end of the mounting plate 319. The output end of the defective product pushing cylinder 320 faces the defective product box 358. After testing, the capacitors that meet the preset requirements are moved to the receiving tray 4 under the drive of the turntable 32, and the good product pushing cylinder 317 drives the pushing plate 318 to move, pushing the capacitors on the turntable 32 into the receiving tray 4. The capacitors that do not meet the preset requirements are moved to the defective product box 358 under the drive of the turntable 32, and pushed into the defective product box 358 by the defective product pushing cylinder 320.

[0046] The rotation drive assembly 34 includes a separator 321, a second drive motor 322, a second driving pulley 323, a second driven pulley 324, and a second transmission belt 325. The input shaft of the separator 321 is coaxially connected to the second driven pulley 324, the output shaft of the separator 321 is coaxially connected to the turntable 32, the output shaft of the second drive motor 322 is coaxially connected to the second driving pulley 323, and the second transmission belt 325 is sleeved around the second driving pulley 323 and the second driven pulley 324. When the second drive motor 322 is turned on, it inputs power to the separator 321 through the second driving pulley 323, the second driven pulley 324, and the second transmission belt 325, which then drives the turntable 32 to rotate.

[0047] In the process of the turntable 32 driving the capacitor to move, the capacitor may tilt. The tilted capacitor is easily misjudged as a defective product and is discharged and stacked in the defective product box 358, which may cause the misjudged capacitor lead to deform, increasing production costs. Therefore, Figures 7-12 The present invention also provides an embodiment to solve the above technical problems.

[0048] The top of the turntable 32 is provided with an annular boss 326, and a plurality of material receiving troughs 33 are arranged on the annular boss 326 and are distributed in an annular shape at equal intervals.

The bowl-shaped elastic part 330 and the suction cup pad 328 form a suction cup space 331. The bottom of the air groove 329 is provided with an air hole 332 that communicates with the suction cup space 331. The closed end of the suction cup cover 360 is provided with a mounting hole, and a sliding rod 333 is passed through the mounting hole. One end of the sliding rod 333 is connected to the bowl-shaped elastic part 330.

[0049] The other end of the sliding rod 333 is connected to the travel rod 334. The inner side of the annular boss 326 is vertically provided with a waist-shaped hole 335 that communicates with the accommodating cavity 327. The travel rod 334 passes through the waist-shaped hole 335. The top of the detection carrier plate 31 is located on one side of the turntable 32 and a support frame 336 is provided. The support frame 336 is provided with an annular guide plate 337. The guide plate 337 is located on the inner side of the annular boss 326. A guide groove 338 is provided on the guide plate 337. The travel rod 334 is inserted into the guide groove 338. The guide groove 338 includes a plurality of connected The first slot segment 339, the second slot segment 340, the third slot segment 341, the fourth slot segment 342, the fifth slot segment 343 and the sixth slot segment 344 extend along the circumference of the guide plate 337. The second slot segment 340, the fourth slot segment 342 and the sixth slot segment 344 intersect with the axis of the guide plate 337. The center line of the first slot segment 339 is higher than the center line of the third slot segment 341. The center line of the third slot segment 341 and the center line of the fifth slot segment 343 are located on the same plane. The end of the first slot segment 339 is The end of the second slot segment 340 is connected to the starting end of the second slot segment 340, the end of the second slot segment 340 is connected to the starting end of the third slot segment 341, the end of the third slot segment 341 is connected to the starting end of the fourth slot segment 342, the end of the fourth slot segment 342 is connected to the starting end of the first slot segment 339, the starting end of the fifth slot segment 343 is connected to the end of the third slot segment 341, the end of the fifth slot segment 343 is connected to the starting end of the sixth slot segment 344, the end of the sixth slot segment 344 is connected to the first slot segment 339, the second slot segment 340 is located between the material transfer carrier plate 21 and the mounting frame, the fourth slot segment 342 is located between the mounting frame and the receiving tray 4, the sixth slot section 344 is located between the receiving tray 4 and the defective product box 358, a hinge block 345 is provided on the outer side of the guide plate 337 and on one side of the fourth slot section 342, a limit plate 346 is hinged on the hinge block 345, an electromagnet 347 is provided on the outer side of the guide plate 337 and on the other side of the fourth slot section 342, and the limit plate 346 is made of magnetic material. When the limit plate 346 is attracted to the electromagnet 347, the side of the limit plate 346 is flush with the inner walls of the third slot section 341 and the fifth slot section 343.

[0050] When a capacitor enters the receiving trough 33, the bottom of the capacitor contacts the bottom of the receiving trough 33, and the bottom of the capacitor and the air groove 329 form a closed adsorption space. In the process of the turntable 32 driving the capacitor to move to the bottom of the first camera 38, the travel rod 334 moves along the first groove section 339, the second groove section 340 and the third groove section 341, thereby driving the sliding rod 333 to move downward, causing the bowl-shaped elastic member 330 to deform to an expanded state, so that the volume of the suction cup space 331 increases, so that the air in the adsorption space formed by the air groove 329 and the bottom of the capacitor is sucked into the suction cup space 331 through the air hole 332, so that a negative pressure is formed between the suction cup pad 328 and the surface of the capacitor, thereby generating suction to adsorb the capacitor, preventing the capacitor from tilting during the movement of the capacitor, so that the capacitor always remains in a vertical state in the receiving trough 33 to the bottom of the first camera 38, so that the first camera 38 and the second camera 39 can avoid capturing the capacitor in the wrong posture and causing misjudgment;

[0051] When the first and second electrodes 330 are pressed against the electrodes 331, the push rod 333 is pressed against the electrodes 332, and the push rod 334 is pressed against the electrodes 333. When the first and second electrodes 331 are pressed against the electrodes 332, the push rod 333 is pressed against the electrodes 333.

[0052] If the capacitor that has been tested is a defective product, the capacitor is driven by the turntable 32 to move from the bottom of the first camera 38 through the receiving tray 4 to the defective product box 358. The good product pushing cylinder 317 does not start working, and the electromagnet 347 starts working to adsorb the limit plate 346. When the stroke rod 334 moves along the third slot section 341 to the connection between the fourth slot section 342 and the fifth slot section 343, under the limiting action of the limit plate 346, the stroke rod 334 moves along the fifth slot section 343 to the sixth slot section 344, and then moves to the first slot section 339 through the sixth slot section 344, so that the capacitor is not desorbed when passing through the receiving tray 4, thereby avoiding the capacitor falling. After the stroke rod 334 returns to the first slot section 339, the adsorption of the capacitor is released. At this time, the capacitor is driven by the turntable 32 to move to the defective product box 358 and is pushed into the defective product box 358 by the defective cylinder.

[0053] After the capacitor on the material transfer carrier plate 21 falls into the material receiving trough 33, it is possible that the capacitor will tilt, and the tilted capacitor is difficult to be adsorbed. Figure 7 、 Figure 13 The present invention also provides an embodiment, in which a correction seat 348 is provided on the inner side of the annular boss 326 and on both sides of the material receiving groove 33, a cavity 361 is provided in the correction seat 348, a disc-shaped rotating block 349 is rotatably installed in the cavity 361, an arc-shaped plate 350 is provided on the outer periphery of the rotating block 349, a slot 351 is provided on the side of the correction seat 348 close to the material receiving groove 33, the end of the arc-shaped plate 350 passes through the slot 351 and is connected to the correction plate 352, and the end of the correction plate 352 extends to the annular boss 326. Above the shaped boss 326, a sliding plate 353 is slidably installed in the cavity 361 below the rotating block 349. A return spring 354 is connected between the starting end of the sliding plate 353 and the inner wall of the cavity 361. The end of the sliding plate 353 passes through the slot 351 and extends to half the width of the waist-shaped hole 335. A plurality of first convex teeth 355 are provided on the outer periphery of the rotating block 349, and a plurality of second convex teeth 356 are provided on the sliding plate 353. The first convex teeth 355 are meshed with the second convex teeth 356.

[0054] When the turntable 32 drives the capacitor to move to the bottom of the first camera 38, the travel rod 334 contacts the sliding plate 353 when moving along the first slot section 339, the second slot section 340 and the third slot section 341, thereby pushing the sliding plate 353 to move in the direction away from the receiving trough 33. With the cooperation of the first protruding tooth 355 and the second protruding tooth 356, the rotating block 349 is driven to rotate, so that the two correction plates 352 are close to each other to correct the tilted capacitor to a vertical state, and then the capacitor is adsorbed by the suction cup pad 328. When the travel rod 334 moves to a certain position, the travel rod 334 will disengage from the sliding plate 353, and the sliding plate 353 moves and resets under the action of the reset spring 354, thereby driving the correction plate 352 away from the capacitor to avoid the correction plate 352 always contacting the capacitor and affecting the detection effect. It should also be noted that an elastic pad can be set on the side of the correction plate 352 close to the capacitor to avoid hard contact between the correction plate 352 and the capacitor, causing damage to the capacitor.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
