Furthermore, in the description of the present invention, "several" means two or more, unless otherwise specifically defined.

[0026] See also Figures 1-4 As shown, the present invention provides a production line cleaning equipment for small-batch, multi-variety electrolytic capacitor aluminum shells, comprising a sealed tunnel-type cleaning device 100, a decontamination device disposed horizontally at the discharge end of the cleaning device 100, and a drying device 300 disposed longitudinally on one side of the discharge end of the decontamination device. The cleaning device 100 includes a mesh conveyor belt 110 for carrying and conveying the aluminum shells, a plurality of pairs of spray pipes 120 disposed above and below the mesh conveyor belt 110, and a visual inspection station 130 disposed above the feed end of the mesh conveyor belt 110. A plurality of atomizing nozzles 121 are embedded in the spray pipe 120, and a water inlet pipe 122 is sleeved between one end of the upper and lower pairs of spray pipes 120, which are connected to the water pump for water supply through a water pipe; the visual inspection station 130 is used to collect image information of the aluminum shell and send it to the central processing unit. The central processing unit identifies the model and contamination degree of the aluminum shell according to the received image information, and generates control instructions accordingly to adaptively adjust the working parameters of the spray pipe 120 and the transmission speed of the mesh conveyor belt 110; the present invention improves the intelligence level and continuous production capacity of the product cleaning process so that it can actively adapt to the rhythm and incoming material changes of the previous processes; and improves the efficiency of the entire production line by adaptively adjusting the cleaning speed.

[0027] Furthermore, the visual inspection station 130 includes an industrial camera and a matching light source installed at the bottom. The number of industrial cameras and light sources is at least two, and the industrial cameras and light sources are spaced apart so that there is no shadow in the illumination range, which is conducive to taking clear pictures so that image processing and judgment can be accurate.

[0028] Specifically, the central processing unit includes an image processing unit for processing image information collected by the visual inspection station 130 and outputting recognition results regarding the aluminum shell model and pollution level; The control logic unit has pre-stored optimal cleaning parameter sets corresponding to different aluminum shell models and pollution levels. The control logic unit is used to call the corresponding cleaning parameter set according to the recognition result and generate control instructions; The central processing unit processes image information in real time, identifies the current aluminum shell model and assesses its surface contamination level. The basis for assessing the contamination level is the grayscale value distribution of pixels in the image, the contrast of specific areas, or the presence of abnormal attachment features. Based on the identified model and contamination level, the central processing unit matches and calls the optimal cleaning parameter set from a pre-stored parameter database. The pre-stored parameter database supports learning and updating through the human-computer interaction interface, and the operator can enter a new aluminum shell model and its corresponding optimal cleaning parameters.

[0029] Furthermore, the mesh conveyor belt 110 is a mesh belt transmission mechanism driven by a stepper motor 111, and its transmission speed is steplessly adjusted by the central processing unit. A water collecting tank 112 is fixedly provided at the bottom of the mesh conveyor belt 110 to collect water sprayed from the spray pipe 120, which flows back into the water tank through pipes and filter membrane filtration equipment and is pumped by the water pump for recycling. A protective cover 140 is provided above the mesh conveyor belt 110, and a number of protective curtains 141 are hung at both ends of the protective cover 140. The protective curtains 141 are plastic sheets, which serve to seal and pass through the aluminum shell at any time.

[0030] like Figures 6-10 As shown, the decontamination device includes a decontamination box 200, a feeding belt 210 installed inside the decontamination box 200, and a feeding device 230 arranged above the discharge end of the decontamination box 200; the feeding belt 210 is a rubber belt driven by a servo motor 211, the feeding end of the feeding belt 210 is located at the bottom of the decontamination box 200, and the discharge end of the feeding belt 210 is located at the top of the decontamination box 200. A number of shifting bars 214 are provided at equal intervals on the upper and lower surfaces of the feeding belt 210 to promote the climbing and transportation of the aluminum shell.

[0031] The feeding end and the discharging end of the feeding belt 210 are both provided with belt rollers 212 for supporting the feeding belt 210 for circulating motion, wherein the feeding end of the feeding belt 210 is lifted upward to the top of the decontamination box 200 and is provided with another belt roller 212. This belt roller 212 is coaxially connected to the servo motor 211 to form a driving force to make the feeding belt 210 circulate in the decontamination box 200 to transport the aluminum shell; at the same time, the servo motor 211 is fixedly connected to the outer wall of the top of the decontamination box 200 by bolts to isolate moisture; in order to make the feeding belt 210 form a high and low end circulating motion, a plurality of pairs of pressure rollers 203 are embedded in the inner wall of the decontamination box 200 for guiding the upper layer of the feeding belt 210 to bend and turn, and at the same time, a belt pressing member 213 is inserted between the inner walls of the decontamination box 200 for cooperating with the pressure roller 203 to guide the lower layer of the feeding belt 210 to bend and turn.

[0032] Furthermore, clean water is placed in the decontamination box 200 and overflows to the top of the feeding end of the feeding belt 210 so that the aluminum shell is placed in the water. A number of ultrasonic generators 220 are installed on the side walls of the decontamination box 200. Ultrasonic waves are emitted by the ultrasonic generators 220 and propagated into the clean water. The ultrasonic waves propagate in the liquid, causing the liquid to vibrate at the ultrasonic frequency. The ultrasonic waves radiate forward in the cleaning liquid in a sparse and dense manner, causing the liquid to flow and generate tens of thousands of tiny bubbles. When the tiny bubbles burst, shock waves are generated to remove dirt and oil stains on the aluminum shell. Furthermore, the central processing unit identifies the aluminum shell model and contamination level based on the received image information, and generates control instructions accordingly to adaptively adjust the working parameters of the spray pipe 120. The working parameters of the spray pipe 120 and the ultrasonic generator 220 include: water pressure and flow, ultrasonic power and action time.

[0033] Specifically, the feeding device 230 is used to push the aluminum shell at the discharge end of the feeding belt 210 onto the drying device 300; the feeding device 230 includes a pushing plate 231, a reciprocating screw rod 232 and a guide frame 233, and the two inner side walls of the guide frame 233 are symmetrically provided with guide grooves 2331, and the guide grooves 2331 are in a rounded rectangular ring structure. Slide columns 2311 are protruded on both sides of the top of the pushing plate 231, and the slide columns 2311 are slidably engaged with the guide grooves 2331. The reciprocating screw rod 232 is arranged on the top center line of the guide frame 233, and the guide grooves 2331 are slidably engaged with the guide grooves 2331. The motor drives the rotation, and a slider 2321 is threadedly connected to the reciprocating screw rod 232; the slider 2321 drives the push plate 231 to reciprocate along the central axis of the reciprocating screw rod 232, and under the circular guidance of the guide groove 2331, the push plate 231 slides between the two lower layers of the guide grooves 2331 and approaches the high-end top surface of the feeding belt 210 to push the material. When the push plate 231 retreats, it slides between the upper layers of the two guide grooves 2331 and stays away from the high-end top surface of the feeding belt 210 to avoid touching the aluminum shell being transported up.

[0034] Furthermore, in order to allow the push plate 231 to automatically bend at the rounded corner of the guide groove 2331, a lifting post 2312 is symmetrically embedded in the top of the push plate 231, and a pair of lifting posts 2312 are plugged into the convex wings on both sides of the slider 2321. The top surface of the guide frame 233 is symmetrically provided with a sliding groove and a pair of lifting posts 2312 for sliding connection; and a spring 234 is sleeved between the convex wings and the top of the lifting post 2312. When the sliding post 2311 of the push plate 231 is located in the middle of the rounded corner of the guide groove 2331, the spring 234 is in a free and stable state; the push plate 231 is pressed and rebounded by the spring 234 to enter the middle of the rounded corner of the guide groove 2331. When the push plate 231 is driven to move horizontally, it bends along the rounded corner and switches between the upper and lower layers of the guide groove 2331.

[0035] like Figure 5 As shown, the drying device 300 consists of a chain-type conveyor mechanism driven by a reduction motor and a protective box on top. Several electric heating tubes are installed in the top of the protective box at the feed end. These tubes can generate heat when powered on. Several temperature sensors are installed on the inner wall of the protective box to monitor the temperature in real time. When the preset drying temperature is reached, the electric heating tubes are powered off, saving electricity. An air cooling device 310 is installed at the top of the discharge end of the protective box. The air cooling device 310 includes several air outlet pipes 311 placed in the top of the protective box and a fan 312 that supplies air to the air outlet pipes 311. The air outlet end of the fan 312 is sheathed with a main air duct 313. An air guide duct 314 is sheathed between the main air duct 313 and the several air outlet pipes 311 to conduct air out of the air outlet pipes 311 and cool the heated aluminum shells for subsequent inspection and packaging.

[0036] Furthermore, a blanking plate 201 is provided on the side wall of the feed end of the decontamination box 200, and the blanking plate 201 is in an upward tilted state and aligned with the discharge end of the mesh conveyor belt 110, so that the aluminum shell on the mesh conveyor belt 110 slides down along the blanking plate 201 into the decontamination box 200 and is transported by the feeding belt 210; a guide plate 202 is provided on the side wall of the discharge end of the decontamination box 200, and the guide plate 202 is in a downward tilted state and aligned with the feed end of the drying device 300, that is, the feed end of the chain plate conveying mechanism, so that the aluminum shell slides in along the guide plate 202 and is transported.

[0037] When used, the production line cleaning equipment for small-batch, multi-variety electrolytic capacitor aluminum shells of the present invention includes the following steps: S1. The aluminum shell is carried by the mesh conveyor belt 110 and conveyed through the visual inspection station 130; S2, the visual inspection station 130 collects image information of the aluminum shell and transmits it to the central processing unit; S3: The central processing unit processes the image information in real time, identifying the current aluminum shell model and assessing its surface contamination level. This assessment is based on the grayscale value distribution of pixels in the image, the contrast of specific areas, or the presence of abnormal attachment features. Based on the identified model and contamination level, the central processing unit matches and calls the optimal cleaning parameter set from a pre-stored parameter database. The pre-stored parameter database supports learning and updating through the human-computer interaction interface, allowing the operator to input a new aluminum shell model and its corresponding optimal cleaning parameters. S4. The central processing unit generates a control instruction to adjust the operating parameters of the spray pipe 120 and the ultrasonic generator 220 and the transmission speed of the mesh conveyor belt 110 to the values ​​set by the optimal cleaning parameter set; S5.
