Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] according to Figure 1-5 As shown, this embodiment provides an automatic cleaning device for the injection port, including a transfer platform 10. The transfer platform 10 is used to place the battery 11, so that the battery 11 can move along the transfer platform 10. Figure 1 The flow proceeds in the direction of the arrow. A heating mechanism 20, a spraying mechanism 30, a wiping mechanism 40, and a drying mechanism 50 are sequentially arranged in the flow direction of the battery 11. These four mechanisms clean the liquid filling port 111 of the battery 11.
[0030] In this embodiment, the electrolytic liquid crystal in the battery 11 injection port 111 is melted by the heating mechanism 20, and then the molten electrolyte is dissolved by the spraying mechanism 30. The injection port 111 is then wiped by the wiping mechanism 40, and finally the injection port 111 is dried by the drying mechanism 50, thus completing the cleaning of the injection port 111.
[0031] The heating mechanism 20 includes a first gas storage tank 21 containing compressed gas. The first gas storage tank 21 is connected in sequence to a first regulating valve 22 and a first heating device 23. The first heating device 23 is provided with a first gas outlet 24. A pressure sensor is installed inside the first gas storage tank 21 to monitor the remaining gas level in real time. The first heating device 23 is provided with a temperature sensor, which allows adjustment of the heating temperature of the first heating device 23. The heating temperature is 40-50℃, which is sufficient to melt the electrolyte crystals at the injection port 111. To achieve a purging effect, the angle of the first gas outlet 24 can be adjusted. To achieve the best heating effect, the inner diameter and angle of the first gas outlet 24 can be adjusted according to the actual situation.
[0032] The spraying mechanism 30 includes a storage tank 31 containing cleaning agent. The storage tank 31 is connected to a spiral tube drip head 33 via a flow control valve 32. The spiral tube drip head 33 drips the cleaning agent around the filling port 111 of the battery 11. The spiral tube drip head 33 is detachably connected to the flow control valve 32. After a period of use, the spiral tube drip head 33 may become clogged. It can be removed and replaced with another spiral tube drip head 33. To prevent cleaning agent overflow or excessively low cleaning agent level, a liquid limiter is provided inside the storage tank 31. The flow control valve 32 can be replaced with a peristaltic pump, which can precisely control the flow rate. The spiral tube drip head 33 can be replaced with a spray head, which sprays the cleaning agent around the filling port 111.
[0033] The wiping mechanism 40 uses non-woven fabric as the wiping material, which is preferably made of cotton. The wiping mechanism 40 includes a feeding device 41, which is connected in sequence to a cutting device 42 and a clamping / releasing device 43. The non-woven fabric roll or sheet is placed in the feeding device 41 for feeding, and then cut by the blade of the cutting device 42. The cut non-woven fabric is then clamped by the clamping / releasing device 43 for use. A wiping rotating head 45 is positioned above the clamping / releasing device 43. The wiping rotating head 45 is connected to a motor 46. By pressing down on the wiping rotating head 45, it comes into contact with the cut non-woven fabric. The cut non-woven fabric wraps around the wiping rotating head 45, reaching the liquid injection port 111. The motor 46 controls the rotation of the wiping rotating head 45 to wipe away the dissolved electrolyte around the liquid injection port 111.
[0034] The wiping mechanism 40 also includes a recycling device 44, which is used to recycle the wiped non-woven fabric. The recycling device 44 collects the non-woven fabric by means of a brush, suction, or blowing. This is because when the recycling device 44 recycles the wiped non-woven fabric, it is easy for the non-woven fabric to stick to the wiping rotating head 45, and external force is needed to tear the non-woven fabric off. The cutting device 42 has a serrated or flat blade. The cutting device 42 cuts the non-woven fabric by means of hot cutting or double-sided cutting. The clamping and releasing device 43 is controlled by a servo motor or cylinder to clamp or release the non-woven fabric. The wiping rotating head 45 is conical or boss-shaped. The downward stroke of the motor 46 is adjusted according to the actual situation and can control the number of times the wiping rotating head 45 rotates forward and backward to achieve the best cleaning effect.
[0035] The drying mechanism 50 includes a second gas storage tank 51 containing compressed gas. The second gas storage tank 51 is connected in sequence to a second regulating valve 52 and a second heating device 53. The second heating device 53 is provided with a second gas outlet 54. A pressure sensor is installed inside the second gas storage tank 51 to monitor the remaining gas level in real time. The second heating device 53 is equipped with a temperature sensor, which allows adjustment of the heating temperature. The drying temperature is 40-50℃, which can dry the area around the liquid injection port 111. To achieve a purging effect, the angle of the second gas outlet 24 can be adjusted. To achieve the best drying effect, the inner diameter and angle of the second gas outlet 54 can be adjusted according to the actual situation.
[0036] The working principle of this embodiment is as follows:
[0037] In this embodiment, a transfer platform 10 is used, and a heating mechanism 20, a spraying mechanism 30, a wiping mechanism 40, and a drying mechanism 50 are sequentially arranged on the transfer platform 10. The battery 11 is placed on the transfer platform 10 for transfer cleaning of the electrolyte inlet 111. Hot air is blown out through the first air outlet 24 of the heating mechanism 20 to melt the electrolyte crystals in the electrolyte inlet 111. Then, the spiral tube dripping head 33 of the spraying mechanism 30 drips cleaning agent into the electrolyte inlet 111 to dissolve the melted electrolyte. Then, the wiping mechanism 40 uses a motor 46 to drive a wiping rotating head 45 covered with cut non-woven fabric to wipe away the dissolved electrolyte around the electrolyte inlet 111. Finally, hot air is blown out through the second air outlet 54 of the drying mechanism 50 to dry the area around the electrolyte inlet 111, thus completing the cleaning of the electrolyte inlet 111 of the battery 11. The transfer platform 10 can hold multiple batteries 11 for simultaneous transfer and cleaning, thereby quickly and efficiently cleaning the surface of the injection port 111, reducing the generation of dirt at the injection port, improving the qualification rate of subsequent products, and also improving the cleaning efficiency of the injection port; at the same time, it reduces the labor intensity of manual cleaning and improves the overall production efficiency.
