The fixing The plate 144 is symmetrically and rotatably connected with clamping plates 143 on both sides. When the weight disk 142 rises, the clamping plates 143 will rotate. The rotation center is the connection between the clamping plates 143 and the fixed plate 144, so that the upper end of the clamping plates 143 moves toward the fixed plate 144 to fix the pins of the capacitor 17. When the weight disk 142 does not rise, the clamping plates 143 move toward the fixed plate 144 under the action of their own gravity. The bottom ends of the two clamping plates 143 are rotatably provided with ball bearings 147. When the rotating motor 146 drives the fixed plate 144 and the clamping plates 143 to rotate, the bottom ends of the ball bearings 147 are in contact with the top end of the weight disk 142. The ball bearings 147 reduce the friction between the clamping plates 143 and the weight disk 142. The top of the machine 1 is rotatably connected with an extrusion block. 145, one side of the top of the squeezing block 145 abuts against the bottom end of the weight disk 142, and the other side of the top of the squeezing block 145 contacts the connecting frame 12, the squeezing block 145 squeezes the weight disk 142, and the weight disk 142 squeezes the clamping plate 143 upward, and the clamping plate 143 rotates, and the front and rear sides of the test bench 15 are rotatably connected with the test board 151, and the connection between the test bench 15 and the test board 151 is provided with a torsion spring, and the test bench 15 and the test board 151 can perform electrical performance tests on the capacitor 17, and the lower ends of the pin detection board 131 and the test board 151 are abutted against the connecting frame 12, and the stepping motor 101, the electric clamp 301, the pin detection table 13, the rotating motor 146 and the test bench 15 are all electrically connected to the console 8.

The vibration plate 2 automatically sorts the capacitors 17 and conveys the capacitors 17 to the discharge guide rail 201. The vibration plate 2 realizes automatic loading of the capacitors 17. , saving labor, the transport mechanism 4 is used to transport the capacitor 17 in the discharge guide rail 201 to the electric clamp 301, and a stop structure (not shown in the figure) is provided at the left end of the discharge guide rail 201 to prevent the capacitor 17 from falling out of the left end of the discharge guide rail 201. The transport mechanism 4 includes a moving frame 401, an elastic member 402, a transport clamp 403, a drive motor 404, a connecting pipe 405, a push block 406 and a protrusion 407. The support frame 11 is slidably connected with the moving frame 401, and the moving frame 401 can move left and right on the support frame 11. An elastic member 402 is connected between the movable frame 401 and the movable frame 401, and the elastic member 402 is a spring. The left end of the movable frame 401 is connected to a transport clamp 403, and the transport clamp 403 is composed of two clamp handles. The clamp handle on one side of the transport clamp 403 is much longer than the clamp handle on the other side. The longer clamp handle is hingedly connected to the movable frame 401, and the shorter clamp handle is fixedly connected to the movable frame 401. The upper parts of the two clamp handles are connected by a tension spring. When the lower end of the longer clamp handle is close to the lower end of the shorter clamp handle, the tension spring is in an unstretched state. A protrusion 407 is provided at the top of the movable frame 401, and a driving motor 404 is provided at the lower part of the support frame 11. A connecting tube 405 is rotatably provided on the inner side of the frame 11. The connecting tube 405 is connected to the driving motor 404 through a pulley transmission member. The driving motor 404 rotates the connecting tube 405 through the pulley transmission member. A pushing block 406 is provided on the upper part of the connecting tube 405.

[0035] like Figure 2 and Figure 4As shown, it also includes a pressing mechanism 5, which includes a pressing plate 501, a connecting thin rod 502, a connecting plate 503 and a trackless cylinder 504. The trackless cylinder 504 is provided on the right side of the top of the machine 1, and the connecting plate 503 is connected to the moving part of the trackless cylinder 504. The connecting thin rod 502 is provided on the rear side of the top of the connecting plate 503.

The transport clamp 403 is located on the upper left side of the discharge guide rail 201. The trackless cylinder 504 drives the connecting plate 503 to move downward, thereby pulling the connecting thin rod 502 and the pressing plate 501 to move downward. The pressing plate 501 moves downward to squeeze the extension rod on the long clamping handle of the transport clamp 403, and the transport clamp 403 is in an open state.

[0036] like Figure 1 and Figure 5 As shown, it also includes a pin straightening mechanism 6, which includes a connecting seat 601, a servo motor 602 and a pin straightening clamp 603. The top of the moving part of the trackless cylinder 504 is provided with a connecting seat 601, and the right end of the connecting seat 601 is connected to the pin straightening clamp 603. The pin straightening clamp 603 consists of a fixed clamp arm and a movable clamp arm. The movable clamp arm is rotatably connected to the connecting seat 601. The movable clamp arm is elastically connected to the connecting seat 601 through a torsion spring (not marked in the figure). The servo motor 602 is provided on the connecting seat 601. The servo motor 60 A pressing block is connected to the output shaft of 2, and the pressing block abuts against the movable clamping arm of the pin straightening clamp 603. The rotation of the servo motor 602 drives the pressing block to rotate and squeeze the movable clamping arm on one side of the pin straightening clamp 603, so that the pin straightening clamp 603 is in an open state. When the capacitor 17 comes to the work station disk 3 and is clamped firmly by the electric clamp 301, the servo motor 602 starts to drive the pressing block to rotate in the opposite direction. The pressing block no longer squeezes the movable clamping arm of the pin straightening clamp 603, and the movable clamping arm of the pin straightening clamp 603 is automatically reset by the torsion spring and cooperates with the fixed clamping arm to clamp the pin of the capacitor 17.

[0037] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes a CCD camera 7 and a lifting frame 701. The lifting frame 701 is provided on the rear side of the top of the machine 1, and the CCD camera 7 is provided on the lifting frame 701. The height of the CCD camera 7 can be adjusted by the lifting frame 701, which is beneficial for the CCD camera 7 to better identify whether the appearance of the capacitor 17 is intact.

[0038] like Figure 1 and Figure 2As shown, the console 8 also includes an alarm light 9. The top of the console 8 is provided with an alarm light 9, which is electrically connected to the console 8. If the electric clamp 301 and other components fail, the console 8 can sound an alarm through the alarm light 9 to remind people that a failure has occurred.

[0039] like Figure 1 , Figure 8 and Fig. 9 As shown, it also includes a collecting mechanism 10, which includes a collecting seat 1001, a scraper 1002, a telescopic cylinder 1003, a rotating slide 1004, a discharging slide 1006 and a collecting plate 1007. The collecting seat 1001 is provided on the left side of the top of the machine 1, and the front end of the collecting seat 1001 is connected to the scraper 1002, and the scraper 1002 can assist the capacitor 17 to separate from the electric clamp 301. The interior of the collecting seat 1001 is hinged with a rotating slide 1004, and the left side of the top of the machine 1 is hinged with The telescopic cylinder 1003, the push rod of the telescopic cylinder 1003 is hinged to the upper rear end of the rotating slide 1004, the capacitor 17 with a complete appearance falls onto the rotating slide 1004, and slides away from the equipment through the collecting seat 1001. The collecting seat 1001 is provided with a discharge slide 1006 inside, and a collecting plate 1007 is provided on the front side of the top of the machine 1. The front end of the discharge slide 1006 contacts the collecting plate 1007, and the capacitor 17 with an incomplete appearance falls onto the discharge slide 1006 and finally slides into the collecting plate 1007.

[0040] like Figure 5 As shown, it also includes a scrap chute 16. The scrap chute 16 is connected to the upper rear side of the stepper motor 101. The scrap chute 16 is located between the test bench 15 and the lifting frame 701. If the capacitor 17 fails to pass the test, when the stepper motor 101 drives the work station 3 to drive the capacitor 17 to rotate to the scrap chute 16, the electric clamp 301 opens, and the capacitor 17 leaves the equipment through the scrap chute 16. An ion fan 18 is provided on the rear side of the top of the machine table 1. When the capacitor 17 reaches the fixing plate 144, the ion fan 18 can remove the static electricity on the surface of the capacitor 17.

[0041] The capacitor 17 to be tested is placed into the vibration disk 2, and the vibration disk 2 is started. The vibration disk 2 automatically sorts the capacitors 17 and conveys the capacitors 17 to the discharge guide rail 201. Initially, the inner side of the transport clamp 403 clamps the capacitor 17, and the pin straightening clamp 603 is in an open state. The driving motor 404 rotates the connecting tube 405 through the pulley transmission member. The connecting tube 405 drives the pushing block 406 to rotate, and the pushing block 406 pushes the protrusion 407 to move to the left, thereby driving the moving frame 401 and the transport clamp 403 thereon to move to the left together. The elastic member 402 changes from an initial state to a compressed state. When the capacitor 17 moves close to the electric clamp 301, the electric clamp 301 opens. When the capacitor 17 moves to the inner side of the electric clamp 301, the pin of the capacitor 17 is located on the inner side of the pin straightening clamp 603, and the electric clamp 301 is controlled to clamp the capacitor 17. Then, the servo motor 602 is started to rotate without contacting the movable clamp arm. The movable clamp arm of the pin straightening clamp 603 is reset under the action of the torsion spring. The pin straightening clamp 603 clamps the pin, and the trackless cylinder 504 is started to drive the connecting plate 503 to move downward, thereby pulling the connecting thin rod 502 and the pressing plate 501 to move downward. The pressing plate 501 moves downward to squeeze one side of the long clamp handle of the transport clamp 403, and the transport clamp 403 releases the capacitor 17. The pin straightening clamp 603 moves downward to straighten the pin. When the pushing block 406 is no longer in contact with the protrusion 407, the elastic member 402 drives the moving frame 401 to reset from the compressed state, and the pressing plate 501 remains in contact with the long clamp handle of the transport clamp 403. The transport clamp 403 is reset to the right in an open state, the stepper motor 101 is started to drive the work station 3 to drive the electric clamp 301 and the capacitor 17 to rotate to the pin detection table 13, when the transport clamp 403 is located outside the capacitor 17 on the leftmost side of the discharge guide rail 201, the trackless cylinder 504 drives the pin straightening clamp 603 and the pressing plate 501 to move upward, the pressing plate 501 no longer presses against the transport clamp 403, and the transport clamp 403 resets to clamp the capacitor 17 under the action of the tension spring, the servo motor 602 is started to drive the pressing block to squeeze the movable clamp arm, so that the pin straightening clamp 603 is opened, and the driving motor 404 drives the moving frame 401 to move to the left again after rotating one circle. This reciprocating process can realize the continuous delivery of the capacitor 17 to the electric clamp 301 of the work station 3.

[0042] When the push rod of the trackless cylinder 504 is extended, the upper part of the pin detection plate 131 is away from the pin detection platform 13, and the pin detection plate 131 is in a compressed deformation state. When the trackless cylinder 504 moves downward, it drives the connecting frame 12 to move downward through the connecting plate 503, and the pin detection plate 131 is driven to rotate under the action of the torsion spring so that its upper end is close to the pin detection platform 13 (the pins of the capacitor 17 are divided into positive and negative poles, the long pin is the positive pole, and the short pin is the negative pole. The positive long pin should be on the inside, the inside here is the side close to the stepper motor 101, and the outside is the side away from the stepper motor 101). If the pin detection plate 131 can contact the pin of the capacitor 17, the positive long pin of the capacitor 17 is on the inside. If the pin detection plate 131 cannot contact the pin of the capacitor 17, the positive long pin of the capacitor 17 should be on the outside.

[0043] If the long positive pin of the capacitor 17 is on the outside, when the stepper motor 101 drives the station disk 3 to drive the capacitor 17 to rotate to the fixed plate 144, and the trackless cylinder 504 drives the connecting frame 12 to move downward, one side of the squeezing block 145 is pressed down, and the other side of the squeezing block 145 is lifted upward, and the squeezing block 145 pushes the weight plate 142 upward. During the upward movement of the weight plate 142, the clamping plate 143 is squeezed, and the lower parts of the clamping plates 143 on both sides are away from each other, and the upper parts of the clamping plates 143 on both sides are close to each other. The pin of the capacitor 17 is clamped, the electric clamp 301 releases the capacitor 17, the rotating motor 146 is started, and the rotating motor 146 drives the fixing plate 144, the clamping plate 143 and the capacitor 17 to rotate 180 degrees, so that the positive long pin of the capacitor 17 rotates to the inside, and then, the trackless cylinder 504 drives the connecting frame 12 to move upward, the squeezing block 145 no longer squeezes the weight plate 142, the weight plate 142 falls to its original position, the clamping plate 143 releases the capacitor 17, and the electric clamp 301 clamps the capacitor 17 again. The stepper motor 101 drives the work station disk 3 to drive the capacitor 17 to rotate to the test bench 15. If the long positive pin of the capacitor 17 is on the inside, the capacitor 17 does not need to rotate 180 degrees, but directly rotates through the fixing plate 144 and then rotates to the test bench 15. The trackless cylinder 504 drives the connecting frame 12 to move downward, and the test plates 151 on both sides rotate close to the long pin and the short pin of the capacitor 17 respectively to detect the capacitor 17. If the capacitor 17 fails the test, when the stepper motor 101 drives the work station disk 3 to drive the capacitor 17 to rotate to the scrap slide 16, the electric clamp 301 opens, and the capacitor 17 passes. The capacitor 17 passes through the scrap chute 16 and leaves the equipment. The capacitor 17 that passes the inspection passes through the scrap chute 16 and the CCD camera 7. The CCD camera 7 inspects the appearance of the capacitor 17 and is rotated by the work station plate 3 to the top of the collecting seat 1001. If the appearance of the capacitor 17 is intact, the electric clamp 301 opens, and the capacitor 17 falls on the rotating chute 1004 and slides out of the equipment through the collecting seat 1001. If the appearance of the capacitor 17 is incomplete, the push rod of the telescopic cylinder 1003 drives the rotating chute 1004 to rotate. At this time, the electric clamp 301 opens, and the capacitor 17 falls on the discharging chute 1006 and finally slides into the collecting plate 1007.

[0044] Embodiment 2: A detection method of a capacitor detection device:

[0045] S1: Place the capacitor 17 to be tested into the vibration disk 2, start the vibration disk 2, the vibration disk 2 transports the capacitor 17 to the discharge guide rail 201, the transport clamp 403 clamps the capacitor 17, the mobile frame 401 moves the transport clamp 403 to the electric clamp 301, the transport clamp 403 releases the capacitor 17, the electric clamp 301 clamps the capacitor 17, and the capacitor 17 is transported to the discharge guide rail 201 through the vibration disk 2, thereby realizing automatic loading of the capacitor 17, and the transport clamp 403 transports the capacitor 17 to the electric clamp 301.

[0046] S2: The stepper motor 101 drives the work station disk 3 to drive the electric clamp 301 and the capacitor 17 to rotate to the pin detection table 13, and the pin detection plate 131 rotates close to the capacitor 17 to detect whether the pin of the capacitor 17 is on the inside. If the long positive pin of the capacitor 17 is on the outside, when the stepper motor 101 drives the work station disk 3 to drive the capacitor 17 to rotate to the fixed plate 144, the upper parts of the clamping plates 143 on both sides are close to each other to clamp the pin of the capacitor 17, and the electric clamp 301 releases the capacitor 17. The rotating motor 146 drives the capacitor 17 to rotate 180 degrees, so that the long positive pin of the capacitor 17 rotates to the inside. The pin detection table 13 is responsible for detecting the pin position of the capacitor 17. The pin detection table 13 cooperates with the rotating motor 146 to ensure that the pin of the capacitor 17 is always on the inside. When the capacitor 17 rotates to the test bench 15, the test boards 151 on both sides rotate close to the long pin and short pin of the capacitor 17 to detect the electrical performance of the capacitor 17.

[0047] S3: For the capacitor 17 that has passed the inspection, the CCD camera 7 will inspect the appearance of the capacitor 17. If the appearance of the capacitor 17 is intact, the capacitor 17 will fall onto the rotating slide 1004, and then slide off the equipment through the collecting seat 1001. The collecting seat 1001 is responsible for collecting the capacitors 17 with intact appearance. If the appearance of the capacitor 17 is incomplete, the capacitor 17 will fall onto the discharging slide 1006, and finally slide into the collecting tray 1007. The collecting tray 1007 is responsible for collecting the capacitors 17 with defects in appearance.
