Description

Technical Field

[0001] The utility model relates to the technical field of new energy insulation coating, in particular to a UV spraying system for insulation of new energy square shell battery cells. Background Art

[0002] In the power battery industry, blue film is still a common solution for cell insulation. However, there are many problems with the actual application of insulating film, such as slow coating speed, limitations on application to complex workpieces, and blistering during battery use. With the rapid development of the new energy vehicle market, green, environmentally friendly, efficient and energy-saving surface coating requirements, UV spraying is a new technical solution in the new energy power battery insulation coating solution. It has 100% solid content, 0VOC, and excellent performance in electrical insulation performance, adhesion ability and bonding strength, and has been favored by new energy vehicle manufacturers.

[0003] During the spraying process, oversprayed paint needs to be intercepted and recycled through a filtering device after interception. Because the wind speed requirements for paint mist interception are very precise, in order to effectively separate the exhaust gas and paint after passing through the interception device, the wind speed control after the paint mist interception device is very important. Too high or too low wind speed will cause the paint mist to be unable to be separated and discharged with the exhaust system, resulting in a large amount of paint waste. Therefore, a good paint mist interception system has become a very critical link. At the same time, it is also necessary to consider many factors such as changes in the type of workpieces on the same production line, changes in production capacity, changes in the spray gun's spraying volume, changes in the air supply volume in the paint spray room, and cleaning after interception. At present, a single fixed maze plate structure is used, which cannot meet the paint mist interception requirements under different working conditions. Unclear interception also causes blockage of the exhaust duct and contamination of the fan by paint. The fixed structure is also not conducive to the cleaning of residual paint mist.

[0022] like Figure 1 , Figure 2 The UV spraying system for insulation of new energy square shell battery cells shown in the figure includes a product conveying mechanism 6, a sealing chamber 1, a spraying mechanism 4, a paint mist intercepting mechanism 3, a paint mist reflux mechanism 5, an exhaust mechanism 8 and an air supply mechanism 2.

[0023] The product conveying mechanism 6 passes through the sealed chamber and is used to automatically convey the product into or out of the sealed chamber 1 . The square shell battery cell is clamped and positioned by the product conveying mechanism 6 .

[0024] There are multiple spraying mechanisms 4 evenly arranged in the sealed chamber 1, which can automatically spray the products passing through the sealed chamber 1 in all directions.

[0025] The paint mist intercepting mechanism 3 is arranged in the sealed chamber 1 and correspondingly arranged on one side of the spraying mechanism 4, and is used to intercept and guide the paint mist after spraying.

[0026] Specifically, combined Figure 3-5 As shown, the paint mist interception mechanism 3 includes a detachable labyrinth plate module, an adjusting screw and a handwheel 3-4, wherein the detachable labyrinth plate module includes a first detachable labyrinth plate module 3-1, a second detachable labyrinth plate module 3-2, and a third detachable labyrinth plate module 3-3 which are arranged in sequence, and an S-shaped labyrinth ventilation channel is formed between the first detachable labyrinth plate module 3-1, the second detachable labyrinth plate module 3-2, and the third detachable labyrinth plate module 3-3, and the adjusting screw includes a front and rear adjusting screw 3-7 and a left and right adjusting screw 3-5, and the front and rear adjusting screw 3-7 is connected to the first detachable labyrinth plate module 3-1, and first hexagonal nuts 3-8 are respectively welded at both ends of the first detachable labyrinth plate module 3-1, and the front and rear adjusting screws 3-8 are respectively threadedly connected to the first hexagonal nuts 3-8. 7. The front and rear adjustment screw rods 3-7 can drive the first detachable maze plate module 3-1 to move forward and backward. The left and right adjustment screw rods 3-5 are connected to the second detachable maze plate module 3-2. The second hexagonal nuts 3-6 are welded on the upper and lower sides of the right side of the second detachable maze plate module 3-2, and the left and right adjustment screw rods 3-5 are respectively threaded on the second hexagonal nuts 3-6. The left and right adjustment screw rods 3-5 can drive the second detachable maze plate module 3-2 to move left and right. The detachable maze plate module 3-3 is fixed and serves as a guide for adjusting the left and right or front and back gaps between the first detachable maze plate module 3-1 and the second detachable maze plate module 3-2. The left and right or front and back gaps and ventilation areas between the first detachable maze plate module 3-1 and the second detachable maze plate module 3-2 can be effectively adjusted by the hand wheel 3-4.

[0027] The paint mist reflux mechanism 5 is arranged in the sealed chamber 1 and correspondingly arranged below the paint mist interception mechanism 3, and is used to collect the paint mist after being intercepted and guided by the paint mist interception mechanism 3.

With the changes in products, production capacity, spraying amount of the spray gun, and air supply volume of the sealed chamber, the paint mist interception mechanism 3 must make different adjustments to change the wind speed to effectively intercept the paint mist. Therefore, the paint mist interception mechanism 3 is designed as a labyrinth air duct, and the left and right or front and back gaps and ventilation areas between the first detachable labyrinth plate module 3-1 and the second detachable labyrinth plate module 3-2 can be effectively adjusted by the hand wheel 3-4 to meet various needs.
