The number of the opening and closing wheel bearings 2326 can be set according to actual conditions. The three straightening arms 233 are located above the opening and closing wheel 232 and are spaced around the capacitor support shaft 231. The opening and closing wheel 232 is provided with three installation shafts 23221 corresponding to the three righting arms 233 at intervals along the circumference. In this embodiment, the outer wall of the opening and closing wheel 232 is provided with three protrusions 2322 at intervals along the circumference, and the tops of the three protrusions 2322 are provided with the three installation shafts 23221 respectively. The righting arm 233 is rotatably sleeved on the outer circumference of the corresponding installation shaft 23221, and the first end of the righting arm 233 is located on the counterclockwise side of the corresponding installation shaft 23221, and the second end of the righting arm 233 is located on the clockwise side of the corresponding installation shaft 23221. The first ends of the three righting arms 233 are close to the capacitor support shaft 231 and are provided with a correction wheel 2332, and the correction wheel 2332 is located above the capacitor support shaft 231. The second end of the righting arm 233 extends in a direction away from the capacitor support shaft 231 and is provided with a mounting rod, and the end of the mounting rod is provided with a connecting wheel 2333.

When the opening and closing wheel 232 rotates in the clockwise direction, the mounting shaft 232 21, the first ends of the three straightening arms 233 can be driven to move toward the direction close to the capacitor support shaft 231, and then the correction wheels 2332 of the three straightening arms 233 can be driven to move toward the direction close to the capacitor support shaft 231, so that the capacitor 200 on the capacitor support shaft 231 can be clamped by the correction wheels 2332 of the three straightening arms 233, and the capacitor 200 on the capacitor support shaft 231 can be clamped by the correction wheels 2332 of the three straightening arms 233, so that the capacitor 200 can be fixed. , by using the correction wheel 2332 to clamp the capacitor 200, when clamping, the correction wheel 2332 and the capacitor 200 form rolling contact, which can avoid scratching the capacitor 200, and by using three straightening arms 233, when the axis of the capacitor 200 is not collinear with the axis of the capacitor support shaft 231, that is, when the capacitor 200 is offset, in the process that the first ends of the three straightening arms 233 approach each other, the capacitor 200 can also be pushed to move in the direction close to the axis of the capacitor support shaft 231, so that the position of the capacitor 200 can be corrected to ensure that the axis of the capacitor 200 is collinear with the axis of the capacitor support shaft 231, that is, the capacitor 200 is located at the center position of the capacitor support shaft 231, and three straightening arms 233 and opening and closing wheels 232 are used at the same time. By adjusting the rotation angle of the opening and closing wheels 232, the distance that the first ends of the three straightening arms 233 move toward or away from the capacitor support shaft 231 can be adjusted, so that capacitors 200 with different outer diameters and heights can be adapted, and the versatility is good and the application range is wide. In other embodiments, the number of the righting arms 233 may be other, such as four, five, six, etc., which can be set according to actual conditions.

[0039] In this embodiment, a convex portion 2331 is formed at the top of the first end of the righting arm 233, and a correction wheel 2332 is provided at the top of the convex portion 2331.

A connecting sleeve 2334 is provided at the bottom end of the righting arm 233, and the connecting sleeve 2334 is rotatably sleeved on the outer periphery of the corresponding installation shaft 23221, and a connecting sleeve bearing 23223 is provided in the connecting sleeve 2334, and the connecting sleeve bearing 23223 is sleeved on the outer periphery of the corresponding installation shaft 23221.

[0040] The turntable device 20 also includes a small plate 24, which is located above the turntable 21 and connected to the turntable drive mechanism 22. The small plate 24 is located between a plurality of fixture mechanisms 23, and a plurality of push mechanisms 25 are arranged at intervals along the circumference of the small plate 24, and the plurality of push mechanisms 25 correspond to the plurality of fixture mechanisms 23 respectively. Among the plurality of push mechanisms 25, two of the push mechanisms 25 correspond to the loading station and the unloading station respectively, and the remaining push mechanisms 25 correspond to the plurality of detection stations one by one. The push mechanism 25 is used to push the opening and closing wheel 232 of the fixture mechanism 23 to rotate in the counterclockwise direction. Specifically, the push mechanism 25 includes a capacitor push cylinder 251 arranged at the top of the small plate 24, and the output end of the capacitor push cylinder 251 protrudes from the outer wall of the small plate 24 and is provided with a capacitor push block 252, and the end of the capacitor push block 252 is provided with a push wheel 253. The outer wall of the opening and closing wheel 232 is provided with a swing arm 2321 in an approximately L shape, the swing arm 2321 is located above the support bearing seat 2313, and the end of the swing arm 2321 protrudes from the outer wall of the support bearing seat 2313 and is provided with an inclined surface 23211. The driving wheel 253 is used to match with the inclined surface 23211 of the swing arm 2321 of the fixture mechanism 23. The capacitor push cylinder 251 is used to drive the capacitor push block 252 to move toward or away from the fixture mechanism 23, thereby driving the driving wheel 253 to move toward or away from the fixture mechanism 23, so that the driving wheel 253 is matched with or separated from the inclined surface 23211 of the swing arm 2321 of the fixture mechanism 23. When the driving wheel 253 is matched with the inclined surface 23211 of the swing arm 2321, as the driving wheel 253 continues to move, the opening and closing wheel 232 can be driven to rotate in the counterclockwise direction through the driving wheel 253 and the swing arm 2321. A turntable elastic member 234 is provided on one side of the swing arm 2321 in the clockwise direction. The turntable elastic member 234 is a tension spring. One end of the turntable elastic member 234 is connected to the swing arm 2321, and the other end of the turntable elastic member 234 is connected to the top of the support bearing seat 2313. When the capacitor 200 on the capacitor support shaft 231 is released by the correction wheel 2332 of the three straightening arms 232, the turntable elastic member 234 is stretched at this time. When the push wheel 253 is separated from the inclined surface 23211 of the swing arm 2321, under the reset action of the turntable elastic member 234, the opening and closing wheel 232 can be driven to rotate to the initial position in the clockwise direction through the swing arm 2321. By adopting the push cylinder 251 and the turntable elastic member 234 to drive the opening and closing wheel 232 to rotate, only one power is needed to complete it, which can save power cost.

[0043] The turntable transmission assembly includes a turntable driving wheel 2231, a turntable driven wheel 2232, and a turntable synchronous belt 2233 sleeved on the outer periphery of the turntable driving wheel 2231 and the turntable driven wheel 2232. The turntable driving wheel 2231 is sleeved on the outer periphery of the output end of the turntable motor 221, and the rotating driven wheel 2232 is sleeved on the outer periphery of the insertion shaft of the divider 222. The top of the frame 10 is provided with an escape hole for the turntable synchronous belt 2233 to escape. The turntable motor 221 is used to drive the turntable driving wheel 2231 to rotate, and under the action of the turntable driven wheel 2232 and the turntable synchronous belt 2233, the input shaft of the divider 222 can be driven to rotate, thereby driving the rotating flange 2221 of the divider 222 to rotate.

[0044] The outer periphery of the turntable driving wheel 2231 , the turntable driven wheel 2232 and the turntable synchronous belt 2233 is provided with a turntable protective cover 2234 , which is arranged on the turntable motor seat 2211 , and the arranged turntable protective cover 2234 protects the turntable driving wheel 2231 , the turntable driven wheel 2232 and the turntable synchronous belt 2233 .

[0045] Combination Figure 12 to Figure 14As shown, a connection mechanism 26 is provided below the turntable 21, and the connection mechanism 26 includes a plurality of adsorption shafts 261, each of which corresponds to a detection station and a capacitor support shaft 231 of a fixture mechanism 23, and the adsorption shaft 261 and the corresponding capacitor support shaft 231 are arranged opposite to each other up and down, and the adsorption shaft 261 is arranged on one side of the connection support seat 26a and can move up and down and rotate relative to the connection support seat 26a, and the connection support seat 26a is arranged at the top of the frame 10. The adsorption shaft 261 is provided with an inner cavity 2611 that passes through along its axial direction, and a joint 2612 is provided at the bottom end of the adsorption shaft 261, and the joint 2612 is connected to the inner cavity 2611, and the joint 2612 is used to connect with a vacuum pumping device. The outer periphery of the adsorption shaft 261 is provided with an upper abutment sleeve 2613, and the upper abutment sleeve 2613 partially protrudes from the top of the adsorption shaft 261. A supporting abutment sleeve 2314 is sleeved on the outer periphery of the capacitor support shaft 231, and the supporting abutment sleeve 2314 corresponds to the upper abutment sleeve 2613 of the corresponding adsorption shaft 261. The bottom end of the supporting abutment sleeve 2314 is flush with the bottom end of the capacitor support shaft 231 and is located below the supporting bearing seat 2313. The supporting abutment sleeve 2314 can move up and down relative to the capacitor support shaft 231. A supporting elastic member 2315 is provided between the supporting abutment sleeve 2314 and the supporting bearing seat 2313. The supporting elastic member 2315 is a compression spring, and the supporting elastic member 2315 is sleeved on the outer periphery of the capacitor support shaft 231. When the adsorption shaft 261 moves upward, the adsorption shaft 261 can drive the upper abutment sleeve 2613 to move upward. When the upper abutment sleeve 2613 contacts the corresponding supporting abutment sleeve 2314, as the upper abutment sleeve 2613 continues to move, the supporting abutment sleeve 2314 can be pushed upward by the upper abutment sleeve 2613 until the top end of the adsorption shaft 261 abuts against the bottom end of the corresponding capacitor support shaft 231. Since the upper abutment sleeve 2613 partly protrudes from the top end of the adsorption shaft 261, when the top end of the adsorption shaft 261 abuts against the bottom end of the corresponding capacitor support shaft 231, the capacitor support shaft 231 partly is located in the upper abutment sleeve 2613, so that the capacitor support shaft 231 can be limited by the upper abutment sleeve 2613. The elastic support member 2315 is compressed, and the inner cavity 2611 is connected to the adsorption cavity 2311 of the corresponding capacitor support shaft 231. The inner cavity 2611 is evacuated through the vacuum equipment via the joint 2612, so that the adsorption cavity 2311 of the corresponding capacitor support shaft 231 can be evacuated. In this way, the corresponding capacitor support shaft 231 and the capacitor 200 on the capacitor support shaft 231 can be sucked, so that the capacitor support shaft 231 and the capacitor 200 on the capacitor support shaft 231 can be adsorbed and fixed. During the vacuuming process, the sealing ring 2312 at the top of the capacitor support shaft 231 can play a sealing role, and then the capacitor support shaft 231 and the capacitor 200 on the capacitor support shaft 231 can be driven to rotate through the adsorption shaft 261.When the inner cavity 2611 and the adsorption cavity 2311 of the corresponding capacitor support shaft 231 are stopped from being evacuated by the vacuum equipment, the corresponding capacitor support shaft 231 and the capacitor 200 on the capacitor support shaft 231 can be stopped from being adsorbed, and the adsorption shaft 261 can be moved downward. In the process of the adsorption shaft 261 moving downward to the initial position, when the upper abutment sleeve 2613 is separated from the supporting abutment sleeve 2314, the supporting elastic member 2315 can be reset to drive the supporting abutment sleeve 2314 to move downward to the initial position.

The rotation motor 271 is connected to the sliding sleeves 262 of the corresponding two adsorption shafts 261 through the rotation transmission assembly. The rotation motor 271 is used to drive the sliding sleeves 262 of the corresponding two adsorption shafts 261 to rotate through the rotation transmission assembly, thereby driving the corresponding two adsorption shafts 261 to rotate, and the upper abutment sleeve 2613 and the joint 2612 can rotate synchronously with the adsorption shaft 261.

In this embodiment, there are multiple, for example three, defective product pushing components 143, and the interior of the defective product storage box 142 is provided with multiple, for example three, defective product storage cavities 1421, and each defective product storage cavity 1421 corresponds to a defective product pushing component 143. It can be understood that the number of defective product pushing components 143 can be set according to actual conditions.

[0086] The good product pushing assembly 145 includes a good product pushing cylinder 1452, which is located above the unloading conveyor line 141 and is connected to the side of one of the conveying mounting seats 1411 away from the center of the unloading conveyor line 141 through the second pushing base 1451. The output end of the good product pushing cylinder 1452 faces the good product storage box 144 and is provided with a good product pushing block 1453. The good product pushing block 1453 corresponds to the feed port 1442 of the good product storage box 144. The good product pushing cylinder 1452 is used to drive the good product pushing block 1453 to move toward or away from the good product storage box 144. The good product pushing block 1453 moves toward the direction close to the good product storage box 144, so that the qualified capacitor 200 on the conveyor belt 1414 of the unloading conveyor line 141 can be pushed into the good product storage box 144 through the feed port 1442 of the good product storage box 144.

[0087] Through the above structure, when the present invention is actually applied, taking the fixture mechanism 23 corresponding to the loading station as an example, after a capacitor 200 (the top of the capacitor 200 faces upward) is transported to the feeding device 30 through the feeding device, the first rotating electric clamp 35 and the second rotating electric clamp 36 are driven downward by the feeding motor 33 until the first rotating electric clamp 35 corresponds to the feeding device and the second rotating electric clamp 36 corresponds to the third rotating electric clamp 414. At this time, the capacitor 200 on the feeding device is located between the two clamping jaws of the first rotating electric clamp 35, and the two clamping jaws of the third rotating electric clamp 36 are located between the two clamping jaws of the second rotating electric clamp 36. Then, the capacitor 200 on the feeding device is clamped by the first rotating electric clamp 35. Then, the feeding motor 33 drives the first rotating electric clamp 35, the capacitor 200, and the second rotating electric clamp 36 to move upward, horizontally toward the turntable 21, and downward, and the rotating motor of the first rotating electric clamp 35 drives the capacitor 200 to flip 180 degrees so that the bottom end of the capacitor 200 faces upward, until the two clamping members of the third rotating electric clamp 414 are located between the two clamping members of the first rotating electric clamp 35, and the second rotating electric clamp 36 is located above the fixture mechanism 23 corresponding to the loading station. At this time, the capacitor 200 is located between the two clamping members of the third rotating electric clamp 141. The capacitor 200 is then clamped by the third rotating electric clamp 414 and released by the first rotating electric clamp 35. The third rotating electric clamp 414 and the capacitor 200 are then driven by the transfer drive mechanism 143 to move in a direction away from the feeding device 30 until the capacitor 200 is located between the first feeding camera 421 and the first feeding light source 425 and below the second feeding light source 427. At the same time, the first rotating electric clamp 35 and the second rotating electric clamp 36 are driven by the feeding motor 33 to move upward, horizontally in a direction away from the turntable 21, and downward. At this time, the first rotating electric clamp 35 corresponds to the feeding device, and the second rotating electric clamp 36 corresponds to the third rotating electric clamp 414.

[0088] Then, the first feeding camera 421 and the second feeding camera 423 take pictures of the bottom of the capacitor 200 respectively, so that the appearance defects of the bottom of the capacitor 200 can be detected. If the detection is qualified, the third rotating electric clamp 141 and the capacitor 200 are driven by the transfer drive mechanism 413 to move to the initial position in the direction close to the feeding device 30. At this time, the capacitor 200 is located between the two clamping jaws of the second rotating electric clamp 36, as shown in FIG. Fig.15As shown. Then the capacitor 200 is clamped by the second rotating electric clamp 36 and released by the third rotating electric clamp 414. Then the capacitor pushing cylinder 251 of the capacitor pushing mechanism 25 corresponding to the loading station pushes the capacitor pushing block 252 to move toward the direction of the fixture mechanism 23 corresponding to the loading station, thereby pushing the opening and closing wheel 232 of the fixture mechanism 23 corresponding to the loading station to rotate in the counterclockwise direction, so as to drive the correction wheels 2332 of the three straightening arms 233 to move away from the capacitor support shaft 231, as shown. Figures 5 to 7As shown, at this time, the turntable elastic member 234 of the jig mechanism 23 is in a stretched state. At the same time, the first rotating electric clamp 35, the second rotating electric clamp 36, and the capacitor 200 are driven by the feeding motor 33 to move upward, move toward the turntable 21, and move downward. The rotating motor of the second rotating electric clamp 36 drives the capacitor 200 to flip 180 degrees, so that the top of the capacitor 200 faces upward, until the second rotating electric clamp 36 is located above the jig mechanism 23 corresponding to the loading station. At this time, the qualified capacitor 200 is placed on the top of the capacitor support shaft 231 of the jig mechanism 23 corresponding to the loading station and is located between the correction wheels 2332 of the three straightening arms 233 of the corresponding jig mechanism 23. Then, the capacitor 200 is released by the second rotating electric clamp 36. Then, the first rotating electric clamp 35 and the second rotating electric clamp 36 are driven by the feeding motor 33 to move upward, move away from the turntable 21, and move downward. At the same time, the capacitor pushing cylinder 251 of the capacitor pushing mechanism 25 corresponding to the loading station pushes the capacitor pushing block 252 to move away from the jig mechanism 23 corresponding to the loading station to the initial position. Under the resetting action of the turntable elastic part 234 of the jig mechanism 23, the opening and closing wheel 232 of the jig mechanism 23 can be driven to rotate in the clockwise direction, so as to drive the correction wheels 2332 of the three straightening arms 233 to move toward the direction close to the capacitor support shaft 231, thereby clamping the capacitor 200 on the capacitor support shaft 231 of the jig mechanism 23. In the above process, while the capacitor 200 on the third rotating electric clamp 414 is clamped by the second rotating electric clamp 36, the next capacitor 200 delivered by the feeding device can be clamped by the first rotating electric clamp 35. When the capacitor 200 on the second rotating electric clamp 36 is placed on the top end of the capacitor support shaft 231 of the jig mechanism 23 corresponding to the loading station, the next capacitor 200 on the first rotating electric clamp 35 is located between the two clamping jaws of the third rotating electric clamp 414. In this way, while the first rotating electric clamp 35 takes material from the feeding device, the second rotating electric clamp 36 takes material from the feeding detection device 40. While the capacitor 200 is sent to the feeding detection device 40 by the first rotating electric clamp 35, the capacitor 200 that has passed the inspection can be sent to the jig mechanism 23 corresponding to the loading station by the second rotating electric clamp 36. The rotating motor of the third rotating electric clamp 414 can drive the capacitor 200 to rotate, so as to adjust the position of the capacitor 200 and facilitate the first feed camera 421 and the second feed camera 423 to take pictures of the bottom end of the capacitor 200.

[0089] If the capacitor 200 fails the test, the third rotating electric clamp 414 and the capacitor 200 are driven by the transfer drive mechanism 413 to move to the initial position in the direction close to the feeding device 30. At this time, the capacitor 200 is located between the two clamping jaws of the second rotating electric clamp 36. Fig.15 As shown. Then the capacitor 200 is clamped by the second rotating electric clamp 36 and released by the third rotating electric clamp 414. The first rotating electric clamp 35, the second rotating electric clamp 36 and the capacitor 200 are driven by the feeding motor 33 to move upward and toward the direction close to the turntable 21, and the capacitor 200 is turned 180 degrees by the rotating motor of the second rotating electric clamp 36, so that the top of the capacitor 200 faces upward until the second rotating electric clamp 36 is located above the inclined plate 123. At this time, the unqualified capacitor 200 is placed on the inclined plate 123, and then the capacitor 200 is released by the second rotating electric clamp 36. The capacitor 200 can slide into the waste box 120 along the inclined plate 123 under its own gravity, so that the unqualified capacitor 200 can be collected by the waste box 120.

[0090] Then, the turntable 21 is driven by the turntable driving mechanism 22 to rotate in the counterclockwise direction, so as to drive the jig mechanism 23 and the capacitor 200 corresponding to the loading station to move to the position corresponding to the first inspection station, and then the top of the capacitor 200 is photographed by the first camera 52, so as to detect the first defect of the appearance of the top of the capacitor 200. Then, the turntable 21 is driven by the turntable driving mechanism 22 to continue to rotate in the counterclockwise direction, so as to drive the jig mechanism 23 and the capacitor 200 corresponding to the loading station to move to the position corresponding to the second inspection station, and then the top of the capacitor 200 is photographed by the second camera 62, so as to detect the second defect of the appearance of the top of the capacitor 200. Then, the turntable 21 is driven by the turntable driving mechanism 22 to continue to rotate in the counterclockwise direction, so as to drive the jig mechanism 23 and the capacitor 200 corresponding to the loading station to move to the position corresponding to the third inspection station. Then, the adsorption shaft 261 corresponding to the third detection station moves upward so that the top end of the adsorption shaft 261 is against the bottom end of the capacitor support shaft 231 of the jig mechanism 23, and the inner cavity 2611 of the adsorption shaft 261 and the adsorption cavity 2311 of the capacitor support shaft 231 of the jig mechanism 23 are evacuated, so that the capacitor support shaft 231 and the capacitor 200 can be adsorbed and fixed, and then the capacitor pushing cylinder 251 corresponding to the third detection station drives the capacitor pushing block 252 to move toward the jig mechanism 23 to push the opening and closing wheel 232 of the jig mechanism 23 to rotate in the counterclockwise direction, so that the capacitor 200 on the capacitor support shaft 231 can be released through the correction wheel 2332 of the three straightening arms 233, and at this time, the turntable elastic member 234 is in a stretched state. Then, the capacitor support shaft 231 and the capacitor 200 of the jig mechanism 23 are driven to rotate by the adsorption shaft 261 corresponding to the third detection station, and the top of the capacitor 200 is photographed by the third camera 72 during the rotation, so as to detect the third defect of the appearance of the top of the capacitor 200. Then, the capacitor push cylinder 251 corresponding to the third detection station drives the capacitor push block 252 to move away from the jig mechanism 23, and under the reset action of the turntable elastic member 234, the opening and closing wheel 232 of the jig mechanism 23 can be driven to rotate in the clockwise direction, so that the capacitor 200 on the capacitor support shaft 231 can be clamped by the correction wheels 2332 of the three straightening arms 233, and at the same time, the capacitor support shaft 231 and the capacitor 200 of the jig mechanism 23 are stopped from being adsorbed by the adsorption shaft 261 corresponding to the third detection station, and moved downward to the initial position.

[0091] Then, the turntable 21 is driven by the turntable driving mechanism 22 to continue to rotate in the counterclockwise direction, so as to drive the jig mechanism 23 and the capacitor 200 corresponding to the loading station to move to the position corresponding to the fourth detection station, and then the adsorption shaft 261 corresponding to the fourth detection station moves upward so that the top end of the adsorption shaft 261 abuts against the bottom end of the capacitor support shaft 231 of the jig mechanism 23, and the inner cavity 2611 of the adsorption shaft 261 and the adsorption cavity 231 of the capacitor support shaft 231 of the jig mechanism 23 are pressed against each other. 1 is vacuumed, so that the capacitor support shaft 231 and the capacitor 200 can be adsorbed and fixed, and then the capacitor push cylinder 251 corresponding to the fourth inspection station drives the capacitor push block 252 to move toward the direction close to the fixture mechanism 23 to push the opening and closing wheel 232 of the fixture mechanism 23 to rotate in the counterclockwise direction, so that the capacitor 200 on the capacitor support shaft 231 can be released through the correction wheels 2332 of the three straightening arms 233, and the turntable elastic member 234 is in a stretched state. Then, the capacitor support shaft 231 and the capacitor 200 of the fixture mechanism 23 are driven to rotate by the adsorption shaft 261 corresponding to the fourth inspection station, and the side of the capacitor 200 is photographed by the fourth camera 83 while rotating, so that the first defect of the appearance of the side of the capacitor 200 can be detected. Then the adsorption shaft 261 corresponding to the fourth detection station stops rotating, and the capacitor push cylinder 251 corresponding to the fourth detection station drives the capacitor push block 252 to move away from the jig mechanism 23, and under the resetting action of the turntable elastic member 234, the opening and closing wheel 232 of the jig mechanism 23 can be driven to rotate in the clockwise direction, so that the capacitor 200 on the capacitor support shaft 231 can be clamped through the correction wheels 2332 of the three straightening arms 233, and at the same time, the capacitor support shaft 231 and the capacitor 200 of the jig mechanism 23 are stopped from being adsorbed through the adsorption shaft 261 corresponding to the fourth detection station, and move downward to the initial position.

[0092] Then, the turntable 21 is driven by the turntable driving mechanism 22 to continue to rotate in the counterclockwise direction, so as to drive the jig mechanism 23 and the capacitor 200 corresponding to the loading station to move to the position corresponding to the fifth detection station, and then the adsorption shaft 261 corresponding to the fifth detection station moves upward so that the top end of the adsorption shaft 261 abuts against the bottom end of the capacitor support shaft 231 of the jig mechanism 23, and the inner cavity 2611 of the adsorption shaft 261 and the adsorption cavity 231 of the capacitor support shaft 231 of the jig mechanism 23 are pressed against each other. 1 is vacuumed, so that the capacitor support shaft 231 and the capacitor 200 can be adsorbed and fixed, and then the capacitor push cylinder 251 corresponding to the fifth inspection station drives the capacitor push block 252 to move toward the direction close to the fixture mechanism 23 to push the opening and closing wheel 232 of the fixture mechanism 23 to rotate in the counterclockwise direction, so that the capacitor 200 on the capacitor support shaft 231 can be released through the correction wheels 2332 of the three straightening arms 233, and the turntable elastic member 234 is in a stretched state. Then, the capacitor support shaft 231 and the capacitor 200 of the fixture mechanism 23 are driven to rotate by the adsorption shaft 261 corresponding to the fifth inspection station, and the side of the capacitor 200 is photographed by the fifth camera 93 while rotating, so that the second defect of the appearance of the side of the capacitor 200 can be detected. Then, the capacitor pushing cylinder 251 corresponding to the fifth detection station drives the capacitor pushing block 252 to move away from the jig mechanism 23, and under the resetting action of the turntable elastic member 234, the opening and closing wheel 232 of the jig mechanism 23 can be driven to rotate in the clockwise direction, so that the capacitor 200 on the capacitor support shaft 231 can be clamped through the correction wheel 2332 of the three straightening arms 233. At the same time, the adsorption shaft 261 corresponding to the fifth detection station stops the adsorption of the capacitor support shaft 231 and the capacitor 200 of the jig mechanism 23, and moves downward to the initial position.

[0093] Then, the turntable 21 is driven by the turntable driving mechanism 22 to continue to rotate in the counterclockwise direction, so as to drive the jig mechanism 23 and the capacitor 200 corresponding to the loading station to move to the position corresponding to the sixth detection station, and then the adsorption shaft 261 corresponding to the sixth detection station moves upward so that the top end of the adsorption shaft 261 abuts against the bottom end of the capacitor support shaft 231 of the jig mechanism 23, and the inner cavity 2611 of the adsorption shaft 261 and the adsorption cavity 231 of the capacitor support shaft 231 of the jig mechanism 23 are pressed against each other. 1 is vacuumed, so that the capacitor support shaft 231 and the capacitor 200 can be adsorbed and fixed, and then the capacitor push cylinder 251 corresponding to the sixth inspection station drives the capacitor push block 252 to move toward the direction close to the fixture mechanism 23 to push the opening and closing wheel 232 of the fixture mechanism 23 to rotate in the counterclockwise direction, so that the capacitor 200 on the capacitor support shaft 231 can be released through the correction wheels 2332 of the three straightening arms 233, and the turntable elastic member 234 is in a stretched state. Then, the capacitor support shaft 231 and the capacitor 200 of the fixture mechanism 23 are driven to rotate by the adsorption shaft 261 corresponding to the sixth inspection station, and the side of the capacitor 200 is photographed by the sixth camera 103 while rotating, so that the third defect of the appearance of the side of the capacitor 200 can be detected.

At the same time, the adsorption of the capacitor support shaft 231 and the capacitor 200 of the jig mechanism 23 is stopped through the adsorption shaft 261 corresponding to the sixth detection station, and the jig mechanism 23 moves downward to the initial position.

[0094] Then, the turntable 21 is driven by the turntable driving mechanism 22 to continue to rotate in the counterclockwise direction, so as to drive the jig mechanism 23 and the capacitor 200 corresponding to the loading station to move to the position corresponding to the unloading station. Then, the unloading motor 133 drives the two unloading jaws 136 to move horizontally and downward in the direction close to the turntable 21 until the two unloading jaws 136 are located above the jig mechanism 23, and the capacitor 200 is located between the two unloading jaws 136. Then, the two unloading jaws 136 are driven to close by the jaw cylinder 135 to clamp the capacitor 200. Then, the capacitor push cylinder 251 corresponding to the unloading station drives the capacitor push block 252 to move in the direction close to the jig mechanism 23, so as to push the opening and closing wheel 232 of the jig mechanism 23 to rotate in the counterclockwise direction, so that the capacitor 200 can be released by the correction wheel 2332 of the three straightening arms 233. Then, the two unloading jaws 136 are driven by the unloading motor 133, and the capacitor 200 moves upward, horizontally toward the unloading classification mechanism 140, and downward, until the two unloading jaws 136 are located above one end of the unloading conveyor line 141, and the capacitor 200 is placed on the conveyor belt 1414 of the unloading conveyor line 141. Then, the two unloading jaws 136 are driven by the jaw cylinder 135 to open to release the capacitor 200, so that the capacitor 200 can be transported through the unloading conveyor line 141. When the first appearance inspection device 50, the second appearance inspection device 60, the third appearance inspection device 70, the fourth appearance inspection device 80, the fifth appearance inspection device 90 and the sixth appearance inspection device 100 all detect that there are no defects in the appearance of the top and the side of the capacitor 200, the capacitor 200 is qualified. At this time, the capacitor 200 is pushed into the good product storage box 144 by the good product pushing component 145 to store the capacitor 200 that has passed the inspection. When any one of the first appearance inspection device 50, the second appearance inspection device 60, the third appearance inspection device 70, the fourth appearance inspection device 80, the fifth appearance inspection device 90 and the sixth appearance inspection device 100 detects that there are appearance defects, the capacitor 200 is unqualified. At this time, the unqualified capacitor 200 is pushed into the defective product storage box 142 by the defective product pushing component 143 to store the unqualified capacitor 200. In this way, the inspection is completed. After the jig mechanisms 23 corresponding to the other workstations are moved to the positions corresponding to the loading workstations driven by the turntable 21, the aforementioned steps can be followed.

[0095] The present invention is provided with a turntable device 20, a feeding device 30, a feeding detection device 40, a plurality of appearance detection devices and a feeding device 110. The feeding device 30 can transfer the capacitor 200 conveyed by the feeding device to the feeding detection device 40, and can transfer the capacitor 200 that has passed the inspection of the feeding detection device 40 to the fixture mechanism 23 of the turntable device 20. The feeding detection device 40 can detect the appearance defects at the bottom of the capacitor 200. The fixture mechanism 23 of the turntable device 20 can fix the capacitor, and the turntable 21 can drive the fixture mechanism 23 and the capacitor to pass through the turntable 21 in sequence. A feeding station, multiple inspection stations and a unloading station, so that the appearance defects on the top and the sides of the capacitor 200 can be inspected through multiple appearance inspection devices, the capacitor 200 can be removed from the fixture mechanism 23 of the turntable device 20 through the unloading device 110, and the removed qualified capacitor 200 and the unqualified capacitor can be stored separately, so that the appearance defects on the bottom, top and sides of the capacitor can be automatically inspected, with a high degree of automation. Compared with the existing manual method, the labor intensity of manual labor is reduced, the production efficiency is greatly improved, and the production cost is reduced. The fixture mechanism 23 of the turntable device 20 includes a capacitor support shaft 231 for supporting the capacitor 200 and a capacitor clamping assembly. The capacitor 200 on the capacitor support shaft 231 can be clamped by the capacitor clamping assembly and the position of the capacitor 200 can be corrected. In this way, in the process of driving the capacitor 200 to move by the turntable 21, the capacitor 200 can be prevented from shaking, and the axis of the capacitor 200 can be ensured to be collinear with the axis of the capacitor support shaft 231, so that the capacitor 200 can be positioned at the center position of the capacitor support shaft 231, the accuracy of the position of the capacitor 200 is ensured, and the detection accuracy is improved. The adsorption chamber 2311, the adsorption shaft 261, the rotation drive mechanism 27 and the movement drive mechanism 28 of the capacitor support shaft 231 can be used to drive the capacitor 200 to rotate, so that a more comprehensive detection of the capacitor 200 can be achieved. At the same time, every two adsorption shafts 261 of the turntable device 20 are driven to rotate by a rotation drive mechanism 27 and driven to move upward by a movement drive mechanism 28, respectively, which can save power costs. The up and down movement of the first rotating electric clamp 35 and the second rotating electric clamp 36 of the feeding device 30 and the horizontal movement toward or away from the turntable 21 are driven by only one feeding motor 33, which simplifies the structure, reduces the volume, reduces the space occupied by the equipment, and saves power costs.The up and down movement of the clamping cylinder 135 and the two unloading clamping jaws 136 of the unloading mechanism 130 of the unloading device 110, and the horizontal movement toward or away from the turntable 21 are driven by only one unloading motor 1331, which simplifies the structure, reduces the volume, reduces the space occupied by the equipment, and saves power costs. The unloading sorting mechanism 140 of the unloading device 110 can automatically classify and store the qualified capacitors 200 and the unqualified capacitors 200 taken from the jig mechanism 23, which greatly meets the production needs, improves production efficiency, and reduces production costs.
