Description

Technical Field

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

[0002] In recent years, the fast charging technology of new energy vehicle power batteries will develop rapidly, and higher requirements are put forward for the insulation and voltage resistance of power battery cells and other components. In order to ensure electrical safety, power battery cells have always required PET "blue film" to be wrapped, but with the substantial increase in working voltage and energy density, this insulation solution has begun to fall behind. At present, we are turning to a new UV insulation coating solution. After the cells are cured by UV spraying, the fixtures carrying the cells will be covered with paint. After being irradiated by a high-pressure mercury lamp, the surface paint layer is difficult to fall off. The paint stuck on the fixture will run repeatedly. During the operation, it is inevitable that some residues will fall on the painting area. Since UV paint is fully recycled and reused, the residues falling on the fixture will enter the paint recovery system. Once the paint system cannot filter out this impurity, it will cause product fixture defects and cause economic losses. Therefore, making an effective online fixture cleaning system will greatly help reduce defective products and improve the quality rate. Utility Model Content

The milling cutter rotating motor 7-2-2 is fixed on the front-and-rear adjustment support 7-2-4. The front-and-rear adjustment servo motor 7-2-3 can drive the front-and-rear adjustment support 7-2-4 to move forward and backward, so that the milling cutter 7-2-1 of the first side cleaning mechanism or the second side cleaning mechanism is close to or away from the side of the product fixture.

[0026] In addition, a side positioning guide mechanism is also provided on the opposite side of the first side cleaning mechanism or the second side cleaning mechanism, and the side positioning guide mechanism includes a guide servo motor 7-2-5 and a guide seat 7-2-6. The guide servo motor 7-2-5 can drive the guide seat 7-2-6 to move forward and backward, so that the guide seat 7-2-6 is close to or away from the side of the product fixture;

[0027] The first side cleaning mechanism or the second side cleaning mechanism is respectively provided with a side dust removal mechanism, and the side dust removal mechanism includes a dust hood 7-2-7 and a dust recovery and exhaust pipeline 7-2-8. The dust hood 7-2-7 is correspondingly arranged on one side of the milling cutter 7-2-1 of the side cleaning mechanism, and the dust hood 7-2-7 is connected to the dust collector 4 through the dust recovery and exhaust pipeline 7-2-8 and the exhaust pipeline 3.

[0028] The top cleaning mechanism includes a connected milling cutter rotating motor 7-1-2 and a milling cutter 7-1-1. The top cleaning mechanism is arranged on an up-and-down adjustment device.

[0030] The products after spraying paint are transferred to the next process, and the jig 6 carrying the products is transported to the cleaning room 1 through the product jig conveying mechanism 5. The cleaning room 1 is provided with an air supply pipeline 2 to supply fresh air into the room, which is used to clean the paint on the surface of the jig by milling. Because the milling cutter will have floating residues when the jig is milled, each milling cutter is provided with a dust hood, and the dust hood is provided with a dust recovery and discharge pipeline, which is sent to the dust collector 4 through the exhaust pipeline 3 to recover the dust;

[0031] The fixture is cleaned by milling. A set of milling cutters are arranged on the top and both sides of the fixture to clean the paint on the fixture surface. The middle tool on the top of the fixture is the top cleaning mechanism 7-1, which is mainly responsible for cleaning the inner groove and two inner walls on the top of the fixture. The milling cutter rotating motor 7-1-2 drives the milling cutter 7-1-1 to rotate for cleaning. In order to ensure the working distance between the milling cutter 7-2-1 and the product fixture 6 and avoid a lot of wear and damage to the fixture itself, an up and down adjustment servo motor 7-1-4 is set to drive the up and down adjustment support 7-1-3 to adjust the up and down distance. A dust removal hood 7-1-5 is set at the milling cutter 7-1-1. After cleaning, the dust is sent to the dust collector 4 through the dust recovery and discharge pipeline 7-1-6 for dust recovery and treatment. The tools on both sides of the fixture are side cleaning mechanisms, which are responsible for cleaning the UV paint and dust on the outer walls on both sides of the fixture. The guide servo motor 7-2-5 of the side positioning guide mechanism drives the guide seat 7-2-6 to clean the product fixture 6.

A dust cover 7-2-7 is set at the milling cutter 7-2-1. After cleaning, the dust is sent to the dust collector 4 through the dust recovery and discharge pipeline 7-2-8 for dust recovery and treatment. The surface material of the product fixture 6 surface is paint fine powder, and about 0.1mm of paint is removed. The dust generated is mainly "paint fine powder". Due to the flammable and explosive nature of paint fine powder, the minimum wind speed standard in the pipeline is: vertical pipeline wind speed (16-18m / s), horizontal pipeline (18-23m / s); then the design wind speed requirement of the exhaust duct 3 nozzle is ≥23m / s for dust collector design.
