Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing, specifically a high-efficiency coating and masking tooling for new energy battery trays. Background Technology

[0002] The battery tray is an important component in new energy vehicles, used to support the power battery. To prevent leakage from the power battery pack from endangering the occupants, the inner cavity of the battery tray needs to be coated with an insulating layer during the manufacturing process. Even if the power battery leaks or is damaged, the battery tray can still maintain its insulation.

[0003] The battery tray insulation layer is applied in a localized manner. Some mounting surfaces and edge beams do not require an insulating coating. Currently, most methods involve locally applying high-temperature masking film for partial masking, followed by spraying the bottom of the tray's inner cavity with a coating gun, and then removing the high-temperature masking film. However, the existing production method has the following drawbacks: 1. The high-temperature masking film is for single use, and the removed film becomes solid waste, posing an environmental problem; 2. The masking film increases production costs; 3. Applying and removing the masking film both require manual labor, which is time-consuming and labor-intensive, hindering production efficiency. Summary of the Invention

[0004] This utility model provides a high-efficiency coating masking fixture for new energy battery trays. The battery tray is embedded and fixed in the groove-shaped inner cavity of the fixture, and the fixture is vertically suspended below the coating production chain to coat the bottom of the inner cavity of the battery tray. The fixture has the advantages of good masking effect and convenient opening and closing, which can reduce production costs, reduce waste, and be environmentally friendly.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A high-efficiency coating and masking fixture for a new energy battery tray is provided. The fixture is a vertically suspended groove-shaped main body with an opening on one side and a fixed back plate on the other side. The bottom of the fixture is a fixed base, and the two sides of the fixture are connected to movable side masking parts by hinges. The top of the fixture is connected to movable top masking parts by hinges.

[0007] The weight of the battery tray is supported by the base, which also covers one side of the battery tray. After the movable side cover and movable top cover are closed, the other three sides of the battery tray are covered and fixed. After the painting is completed, the movable side cover and movable top cover can be opened to remove the battery tray, which is convenient and quick.

[0008] Several lifting lugs are installed on the top of the main body of the tooling. The tooling is vertically suspended on the chain production line via the lifting lugs for circulation.

[0009] The movable side shield and the movable top shield consist of a frame and a skin fixed to the frame.

[0010] The movable side shield is provided with a pin ring at its edge, and the movable top shield is provided with a matching pin ring at its edge. When the movable side shield and the movable top shield are in the closed state, the two pin rings are in contact, and a pin is inserted into the pin hole to fix the movable top shield and the movable side shield, thereby locking the battery tray in the inner cavity of the tooling.

[0011] A positioning block is provided on the inner side of the base. The positioning block matches the edge of the middle beam of the battery tray, which can ensure the fixed position of the battery tray within the tooling.

[0012] Advantages of this utility model:

[0013] 1. This utility model is specifically used for the production of hanging coating for battery trays of new energy vehicles. It has the advantages of good masking effect and convenient opening and closing. It changes the current situation of using masking film to cover and paste the surface of battery trays, reduces production costs, reduces the difficulty of pasting and coating, and can reduce waste and is green and environmentally friendly.

[0014] 2. The tooling of this utility model adopts a welded frame + skin riveting structure. The frame is made of 15×15×2.0 steel pipe and the skin is made of 0.5mm aluminum plate; the load-bearing capacity can reach 60kg.

[0015] 3. This utility model tooling has good locking and positioning effects, ensuring the consistency of coating. Attached Figure Description
