[0027] See also Figure 1-Figure 3 and Figure 8A capacitor appearance inspection mechanism is provided on a fixed base 50 of a machine platform 40. The capacitor appearance inspection mechanism includes a conveying unit 10, a driving unit 20, a detection unit 30, and a controller. The driving unit 20 is used to drive the conveying unit 10, which is used to transport the capacitor 100 to be inspected.

The controller is used to analyze the inspection data transmitted by the detection unit 30 and control the operation and coordination of the conveying unit 10, the driving unit 20, and the detection unit 30.

[0028] More specifically, the detection unit 30 detects whether the top surface 101 , the bottom surface 102 , and the side circumference 103 of the capacitor 100 are deformed and whether the dimensions meet the production requirements.

[0029] The conveying unit 10 includes a first transfer component 11 and a second transfer component 12, and the detection unit 30 includes a first detection component 31 and a second detection component 32. The first transfer component 11 and the second transfer component 12 are arranged side by side on the side wall of the fixed seat 50, and the first detection component 31 and the second detection component 32 are respectively located above the first transfer component 11 and the second transfer component 12. The first transfer component 11 is used to transfer capacitors 100, the first detection component 31 is used to detect capacitors 100 on the first transfer component 11, and the second transfer component 12 is used to transfer capacitors 100 that have passed the inspection on the first transfer component 11, and the second detection component 32 is used to detect capacitors 100 on the second transfer component 12.

[0030] The first transfer assembly 11 includes a first turntable 111 rotatably connected to the fixing base 50 and at least one first manipulator 112 disposed on the first turntable 111, the first manipulator 112 extending radially and used to clamp the capacitor 100 to be tested.

[0031] The driving unit 20 includes a synchronous transmission component 21 and a cam 223 driving component 22. The synchronous transmission component 21 is connected to the first turntable 111 and the second turntable 121. The cam 223 driving component 22 is connected to the synchronous transmission component 21. The cam 223 driving component 22 can drive the first turntable 111 and the second turntable 121 to rotate synchronously in the same direction through the synchronous transmission component 21.

[0032] During operation, the first transfer component 11 transfers the capacitors 100 that have passed the inspection of the first detection component 31 to the second transfer component 12, and the first transfer component 11 transfers the capacitors 100 that have failed the inspection of the first detection component 31 to the bottom of the first turntable 111 for unloading; the second transfer component 12 transfers the capacitors 100 that have passed the inspection of the second detection component 32 to the next process, and the second transfer component 12 transfers the capacitors 100 that have failed the inspection of the second detection component 32 to the bottom of the second turntable 121 for unloading.

[0033] The working process of the capacitor appearance detection mechanism:

[0034] In this embodiment, the cam 223 driving assembly 22 drives the first turntable 111 and the second turntable 121 to rotate synchronously in the clockwise direction through the synchronous transmission assembly 21, and the first manipulator 112 and the second manipulator 122 also rotate synchronously in the clockwise direction.

[0035] The capacitor appearance inspection mechanism feeds horizontally from the left side of the first transfer component 11, and the first manipulator 112 clamps the capacitor 100 and drives the capacitor 100 to rotate clockwise. When the capacitor 100 moves to directly below the first inspection component 31 and is in a vertical state, the first inspection component 31 performs an appearance inspection on the top surface 101 of the capacitor 100 and transmits the inspection data to the controller, and the controller analyzes the inspection data; if the appearance inspection of the top surface 101 of the capacitor 100 is qualified, the first manipulator 112 drives the capacitor 100 close to the second transfer component 12 and transfers the capacitor 100 to the second manipulator 122; if the appearance inspection of the top surface 101 of the capacitor 100 is unqualified, the first manipulator 112 drives the capacitor 100 to move to directly below the first turntable 111 and releases the capacitor 100 for unloading, and the workers recycle the unqualified capacitors 100.

[0036] During the process of the first manipulator 112 transferring the capacitor 100 to the second manipulator 122 , when the capacitor 100 is in a horizontal state, the second manipulator 122 clamps the lead 104 of the capacitor 100 , while the first manipulator 112 releases the capacitor 100 , and the first manipulator 112 completes the transfer of the capacitor 100 . When the second manipulator 122 drives the capacitor 100 to move to the inspection area of ​​the second inspection component 32 and the capacitor 100 is in a vertical state, the second inspection component 32 performs an appearance inspection on the bottom surface 102 and the side 103 of the capacitor 100 and transmits the inspection data to the controller, and the controller analyzes the inspection data; if the appearance of the bottom surface 102 and the side 103 of the capacitor 100 are both qualified, the second manipulator 122 transfers the capacitor 100 to the right side of the second turntable 121. At this time, the capacitor 100 is in a horizontal state, and the mechanism of the next process clamps the capacitor 100; if the appearance inspection of the bottom surface 102 or the side 103 of the capacitor 100 is unqualified, the second manipulator 122 drives the capacitor 100 to move to the bottom of the second turntable 121 and releases the capacitor 100 for unloading, and the workers recycle the unqualified capacitors 100.

[0037] As described above, the capacitor appearance inspection mechanism proposed in the present invention, through the cooperation of the conveying unit 10, the detection unit 30, the drive unit 20, and the controller, enables the smooth transportation, inspection, and unloading and recycling of the capacitor 100, thereby achieving a high degree of automation of the capacitor appearance inspection mechanism, reducing personnel costs and improving inspection efficiency; through the cooperation of the detection unit 30 and the controller, a more accurate inspection of the appearance of the capacitor 100 is achieved, which greatly reduces the inspection error compared to manual inspection; through the cooperation of the drive unit 20 and the conveying unit 10, the first turntable 111 and the second turntable 121 can rotate synchronously in the same direction, achieving efficient transportation efficiency, thereby improving production efficiency. The capacitor appearance inspection mechanism not only has a high degree of automation, improves inspection efficiency, and reduces production costs, but also reduces inspection errors, thereby improving the yield of the capacitor 100.

The swing arm 215 is connected to the first transmission disc 211 and the second transmission disc 212 to enable the first transmission disc 211 and the second transmission disc 212 to rotate synchronously. The first transmission disc 211 and the second transmission disc 212 respectively drive the first rotating disc 111 and the second rotating disc 121 to rotate, thereby achieving synchronous rotation of the first manipulator 112 and the second manipulator 122 in the same direction.

[0041] More specifically, the synchronous transmission assembly 21 also includes a first ball head connecting rod 213 and a second ball head connecting rod 214.

During operation, the driving device 221 drives the cam 223 to rotate via the driving shaft 222. The rotational motion of the cam 223 is converted into the up and down swinging of the movable rod 224 on the cam 223, thereby driving the up and down movement of the third ball-end connecting rod 225, thereby driving the conveying unit 10.
