Technical Field

[0001] This invention relates to a production equipment for aluminum electrolytic capacitors, and more particularly to a cleaning, discharging, and unloading device for aluminum electrolytic capacitors. Background Technology

[0002] During the production of aluminum electrolytic capacitors, the surface of the aluminum shell needs to be cleaned before the sleeving process. This is because during the impregnation of the core of liquid aluminum electrolytic capacitors, the anode and cathode leads become contaminated with electrolyte. In contrast, during the impregnation, dispersing, and assembly processes of solid aluminum electrolytic capacitors, the positive and negative leads, the lead holes of the rubber stoppers, and the outer surface of the solid aluminum electrolytic capacitors become contaminated with conductive polymers and other oily impurities.

[0003] For example, in patent CN109865731A, currently, cleaning aluminum electrolytic capacitors requires placing the product in a special cleaning box for cleaning. After cleaning, the product needs to be poured from the cleaning box into a turnover box. However, currently, the turnover box still needs to be manually placed into the unloading machine, which still requires a lot of manpower. Summary of the Invention

[0026] It should be noted that when a component is described as being "fixed to, attached to, connected to or connected to" another component, it can be directly fixed to, attached to, connected to or connected to the other component, or it can be indirectly fixed to, attached to, connected to or connected to the other component through other intermediate connectors.

[0027] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of the invention.

[0028] Example 1

[0029] like Figure 1 The device shown is an aluminum electrolytic capacitor cleaning and unloading device, comprising a docking roller line 1, a unloading mechanism 2, a receiving hopper 3, and a frame conveying assembly 4. The docking roller line 1 is connected to the unloading mechanism 2, and the receiving hopper 3 is located on one side of the unloading mechanism 2. The unloading mechanism 2 unloads the aluminum electrolytic capacitors of the cleaning frame 6 transported from the docking roller line 1 into the receiving hopper 3. Figure 2As shown, the plastic frame conveying assembly 4 includes a plastic frame support 41, a guide frame, a plastic frame conveying line 43, a frame placement assembly 44, a plastic frame fixing assembly 45, and a frame pushing cylinder 46. The guide frame is fixedly mounted on the plastic frame support 41. The plastic frame conveying line 43 is located below the receiving hopper 3. The frame placement assembly 44 picks up the plastic frame from the guide frame and lowers it to the position of the frame pushing cylinder 46. The frame pushing cylinder is located at one end of the plastic frame conveying line 43. The frame pushing cylinder 46 pushes the plastic frame onto the plastic frame conveying line 43 directly below the receiving hopper 3. The plastic frame fixing assembly 45 includes two plastic frame fixing cylinders 451 arranged opposite each other. The plastic frame fixing cylinders 451 can fix the plastic frame inside the guide frame.

[0030] In this embodiment, the operator only needs to place the plastic frame 7 into the guide frame. Under the action of the frame placement assembly 44, the plastic frame will be lowered to the position of the frame pushing cylinder 46. The telescopic rod of the frame pushing cylinder 46 will send the lowered plastic frame 7 to the bottom of the receiving hopper 3. After the plastic frame receives the aluminum electrolytic capacitor poured into it from the cleaning frame 6 by the pouring mechanism 2 from the receiving hopper 3, the plastic frame conveying line 43 will start and transport the plastic frame containing the aluminum electrolytic capacitor away. It can be seen that in this embodiment, the plastic frame conveying assembly can transport the plastic frame to the bottom of the receiving hopper without manual intervention. The operator only needs to place the plastic frame on the guide frame, thereby saving manpower.

[0031] In this embodiment, a plastic frame fixing component 45 is placed in the middle of the guide frame. Under the action of the plastic frame fixing component 45, the plastic frame will not fall down by itself. Only when the plastic frame fixing component 45 is opened can the plastic frame descend with the frame placement component 44. In this embodiment, the plastic frame fixing component 45 includes two plastic frame fixing cylinders 451 arranged opposite to each other. The two plastic frame fixing cylinders 451 are fixedly mounted on the plastic frame support 41. A fixing plate 452 is provided on the telescopic rod of the plastic frame fixing cylinder 451. The fixing plate 452 extends and presses against the plastic frame, thereby fixing the plastic frame. A frame placement sensor is provided on the plastic frame support 41. The frame placement sensor is connected to the frame placement component 44 and the plastic frame fixing cylinders 451 through a PLC.

[0032] In this embodiment, when the plastic frame 7 placed in the guide frame moves to the position of the frame placement sensor, the frame placement sensor causes the extension rods of the two oppositely arranged plastic frame fixing cylinders 451 to extend through the PLC, and the two fixing plates 452 clamp the plastic frame to prevent the plastic frame from falling further.

[0033] In this embodiment, as Figure 3As shown, the frame placement assembly 44 includes a frame placement cylinder 441 and a receiving plate 442, with the receiving plate 442 connected to the telescopic rod of the frame placement cylinder 441. Under the action of the frame cylinder, the receiving plate 442 rises to the position where the plastic frame is fixed. At this time, the frame placement sensor, through the PLC, causes the telescopic rods of the two oppositely arranged plastic frame fixing cylinders 451 to retract. The fixing plate 452 then releases the plastic frame, which falls onto the support plate and descends with it. In this embodiment, the plastic frames within the guide frame are stacked one by one. Therefore, when the corner of the plastic frame on the support plate descends to the height of one plastic frame, the frame placement sensor, through the PLC, causes the telescopic rods of the two oppositely arranged plastic frame fixing cylinders 451 to extend, thus the fixing plate 452 clamps the upper plastic frame. In this way, one plastic frame 7 descends to the position of the frame pushing cylinder 46 each time it follows the receiving plate 442.

[0034] In this embodiment, the guide frame includes eight vertically arranged guide strips 42, all of which are fixedly mounted on the frame bracket 41 to form a receiving channel for the frame 7. In this embodiment, the eight guide strips 42 are evenly divided into four groups, and the four groups of guide strips 42 are respectively arranged in four directions to form a square receiving channel, the size of which matches the size of the frame 7.

[0035] In this embodiment, as Figure 4 and Figure 5 As shown, the material pouring mechanism 2 includes a material pouring support 21, a tilting device 22, and a carrying roller line 23. The carrying roller line 23 is connected to the material pouring support 21 by four carrying cylinders 25, which are respectively located at the four corners of the carrying roller line 23. The tilting device 22 includes a cleaning frame fixing assembly 221, a tilting shaft 222, and a tilting motor 223. The cleaning frame fixing assembly 221 is fixedly connected to the tilting shaft 222, and the tilting shaft 222 is connected to the tilting motor 223. When the cleaning frame is tilted, the cleaning frame fixing assembly 221 fixes the cleaning frame 6 on the carrying roller line 23 to the tilting shaft 222.

[0036] In this embodiment, the cleaning frame 6 exiting the cleaning machine is placed on the docking roller line 1. The cleaning frame 6 moves from the docking roller line 1 to the carrying roller line 23, where it is then unloaded. When the heights of the docking roller line 1 and the carrying roller line 23 do not correspond, the height of the carrying roller line 23 can be adjusted using the carrying cylinder 25 to ensure that the docking roller line 1 and the carrying roller line 23 can be docked, thus allowing the cleaning frame 6 to move smoothly from the docking roller line 1 to the carrying roller line 23. In this embodiment, both the docking roller line 1 and the carrying roller line 23 include multiple rollers arranged side by side. One end of the rollers on the docking roller line 1 is connected to a chain via gears, and one end of the rollers on the carrying roller line 23 is also connected to a chain via gears. The chain on the docking roller line 1 is connected to a first roller motor, and the chain on the carrying roller line 23 is connected to a second roller motor.

[0037] In this embodiment, as Figure 6 As shown, the cleaning frame fixing assembly 221 includes a flip bracket 2211, a connecting front plate 2212, a fixing block 2213, and a buckle assembly. The flip bracket 2211 is connected to the connecting front plate 2212, and the connecting front plate 2212 is fixedly connected to the flip shaft 222. The fixing block 2213 is disposed on the connecting front plate 2212, and the cleaning frame 6 is provided with a first fixing position corresponding to the fixing block 2213. The buckle assembly includes a buckle cylinder 2214 and a buckle member 2215. The buckle cylinder 2214 is fixedly connected to the flip bracket 2211, and the buckle member 2215 is connected to the telescopic rod of the buckle cylinder 2214. The cleaning frame 6 is provided with a second fixing position corresponding to the buckle member 2215. The first fixing position and the second fixing position are respectively located on two sides of the cleaning frame. In this embodiment, after the cleaning frame moves from the docking roller line 1 to the carrying roller line 23, the latch cylinder 2214 is activated, causing the latch 2215 to engage the second fixing position and the first fixing position to press against the fixing block 2213, thereby fixing the cleaning frame onto the flipping bracket 2211 and the connecting front plate 2212. Then, the flipping motor 223 drives the flipping shaft 222 to rotate, and the cleaning frame fixing assembly 221 flips along with the cleaning frame, thereby pouring the aluminum electrolytic capacitors inside the cleaning frame into the receiving hopper 3.

[0038] In this embodiment, as Figure 7 and Figure 8As shown, the unloading mechanism 2 can also be equipped with a cleaning frame moving assembly 24 to help fix the cleaning frame and unload materials. The cleaning frame moving assembly 24 has a rotating shaft 242 and multiple side-by-side carrying moving belt assemblies 241. The multiple carrying moving belt assemblies 241 are connected to the same rotating shaft 242. The rotating shaft 242 is connected to a rotary motor 243 via a belt or chain. Both ends of the rotating shaft 242 are connected to the tilting bracket 2211 via bearings. The carrying moving belt assembly 241 includes a carrying belt 2411, a driving bearing 2412, and a driven bearing 2413. Both ends of the carrying belt 2411 are connected to the driving bearing 2412 and the driven bearing 2413, respectively. The driven bearing 2413 is connected to the tilting bracket 2211 via a connecting shaft, and the driving bearing 2412 is connected to the rotating shaft 242.

[0039] In this embodiment, when the cleaning frame moves onto the support roller 23, the height of the support roller 23 needs to be higher than the height of the support belt 2411. After the cleaning frame has fully moved onto the support roller 23, the support cylinder 25 is activated, so that the height of the support roller 23 needs to be lower than the height of the support belt 2411. At this time, the cleaning frame is supported by the support belt 2411. To facilitate the fixing of the cleaning frame, driven by the rotary motor 243, the support belt 2411 moves the cleaning frame toward the fixing block 2213, so that the first fixing position on the cleaning frame abuts against the fixing block 2213. Then, the latch cylinder 2214 is activated, so that the latch 2215 latches the second fixing position, thereby completing the fixing of the cleaning frame.

[0040] In this embodiment, after the cleaning frame is flipped and unloading is completed, the flipping motor 223 flips the cleaning frame back, the latch cylinder 2214 is activated, causing the latch 2215 to release from the second fixing position; then the rotation motor 243 drives the carrier belt 2411, causing the cleaning frame to exit the carrier roller line 23 and enter the unloading roller line 5, completing the unloading of the cleaning frame. Throughout the entire unloading process of the cleaning frame, the height of the carrier belt 2411 is higher than the height of the carrier roller line 23.
