Description

Technical Field

[0001] This utility model relates to the field of battery tray processing technology, specifically to a composite cleaning process production line for the surface of aluminum alloy battery trays. Background Technology

[0002] In recent years, with the rapid development of new energy vehicles, the battery trays or battery boxes that house the battery packs are mostly made of aluminum alloy. After the aluminum alloy battery box completes the machining process, it needs to undergo surface spraying or oxidation treatment to obtain a denser, more wear-resistant, or more corrosion-resistant coating or oxidized surface. Alternatively, an insulating and voltage-resistant layer may be applied to the surface of the battery tray to improve its safety. Therefore, before entering the surface treatment process, oil, impurities, and other contaminants on the surface of the battery box must be removed to avoid adverse effects on subsequent surface treatments.

[0003] Typically, the pre-treatment cleaning of battery boxes is done manually. The battery boxes are moved by overhead cranes or hoisting devices and cleaned by spraying water or cleaning solutions, or by immersing the entire tray in cleaning solutions. Although most of the stains on the battery boxes can be removed, traditional cleaning methods still cannot achieve a thorough cleaning effect due to the presence of many small bends and cleaning dead zones in the battery boxes. Summary of the Invention

[0004] The purpose of this utility model is to provide a battery tray surface cleaning production line, which is specifically designed for cleaning the surface of battery trays. Through weld grinding, robotic laser cleaning, alcohol spraying + wiping, and high-pressure dry ice spraying, the cleaning process achieves efficient and high-quality cleaning of battery trays. It has the advantages of good cleaning effect, high efficiency, and compact structure.

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

[0006] A composite cleaning process for aluminum alloy battery tray surfaces includes a longitudinal flow roller table connected to a vertically connected feed roller table via a universal turntable. The longitudinal flow roller table is also equipped with a robotic laser cleaning device and an alcohol spraying device in sequence. The end of the longitudinal flow roller table is connected to a vertically connected dry ice cleaning roller table via a universal turntable. Several dry ice cleaning machines are placed on the side of the dry ice cleaning roller table.

[0007] The laser cleaning device includes: the laser head of the laser cleaning machine is mounted on the robotic arm; a high-energy laser beam irradiates the surface of the workpiece, causing the dirt, rust, or coating on the surface to evaporate or peel off instantly, effectively and quickly removing the adhering substances or surface coatings from the object being cleaned, thereby achieving the effect of cleaning the workpiece.

[0008] The operator holds a dry ice spray gun, and high-pressure dry ice is sprayed from the nozzle onto the surface of the battery tray to clean out impurities from the tray gaps; after cleaning, the dry ice evaporates directly into CO2 and dissipates without leaving any residue.

[0009] The alcohol spray device includes an alcohol tank, inside which a submersible pump is installed. The submersible pump is connected via a hose to the inlet of a solenoid valve mounted on the top crossbeam. The outlet of the solenoid valve is connected to a shaping hose, with the outlet of the shaping hose facing downwards toward the upper surface of the battery tray.

[0010] When the battery tray reaches its designated position and alcohol needs to be sprayed onto the battery tray below, the operator presses a button. 95% pure alcohol is pumped from the alcohol tank by a submersible pump and sprayed onto the battery tray through a solenoid valve and a flexible hose. The solenoid valve opens for a delay and then closes, while the submersible pump is also powered off.

[0011] The dry ice cleaning roller table consists of several sections, each vertically connected to the longitudinal flow roller table via a universal turntable. The dry ice cleaning roller table provides the operator with the working height for dry ice cleaning.

[0012] The battery tray assembly line operation is as follows: The battery tray is moved onto the feeding roller table from the storage area at the head end; the weld seams are ground and slag removed using a wire brush wheel on the feeding roller table; it then enters the laser cleaning device on the longitudinal flow roller table for cleaning; it enters the alcohol spray device for alcohol spraying; the battery tray is manually wiped to remove oil or ink; it then enters the dry ice cleaning roller table for manual dry ice spray cleaning; cleaning is completed, and the battery tray is unloaded from the production line.

[0013] Advantages of utility models

[0014] The battery tray in this invention undergoes a series of cleaning processes, including weld grinding, robotic laser cleaning, alcohol spraying and wiping, and high-pressure dry ice spraying, to achieve efficient and high-quality cleaning of the battery tray.

[0015] The entire clean production line has a compact structure and occupies a small area.

[0016] This utility model provides a battery tray assembly line with high transfer efficiency, eliminating the need for overhead cranes and lifting equipment in the workshop. Attached Figure Description
