Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a high-frequency weld laser cleaning equipment for an automotive battery liquid cooling plate. Background Technique

[0002] A battery liquid cooling plate is a device that uses liquid for heat dissipation. Usually, liquids such as water and ethylene glycol are used for circulating heat dissipation. In an electric vehicle, the battery is the core equipment. It undergoes a large amount of charging and discharging, generating a large amount of heat. If this heat cannot be dissipated in time, the temperature of the entire battery system will rise, having a negative impact on the system operation. The battery liquid cooling plate keeps the battery temperature within an appropriate range by flowing the coolant over the battery surface. During the production of the automotive battery liquid cooling plate, cleaning equipment is required to clean oxides, oil stains, welding slag, etc. adhered to the surface of the battery liquid cooling plate.

[0003] However, the traditional cleaning equipment has the following disadvantages:

[0004] The traditional cleaning equipment cleans by friction contact between the grit and the impurities adhered to the surface of the battery liquid cooling plate. Although the impurities on the surface of the battery liquid cooling plate are cleaned off, scratches are generated after the friction between the grit and the battery liquid cooling plate, shortening the service life of the battery liquid cooling plate itself. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-frequency weld laser cleaning equipment for an automotive battery liquid cooling plate, so as to solve the problem in the above-mentioned background technique that the traditional cleaning equipment cleans by friction contact between the grit and the impurities adhered to the surface of the battery liquid cooling plate. Although the impurities on the surface of the battery liquid cooling plate are cleaned off, scratches are generated after the friction between the grit and the battery liquid cooling plate, shortening the service life of the battery liquid cooling plate itself.

[0006] To achieve the above object, the present utility model provides the following technical solutions: a high-frequency weld laser cleaning device for an automotive battery liquid cooling plate, including a cleaning machine housing. A cleaning opening is provided in the middle of one side of the cleaning machine housing. Operating mechanisms are fixedly installed at both ends of one side of the cleaning machine housing. A conveying platform is fixedly installed in the middle of the inner wall of the cleaning machine housing. A linear track is fixedly installed on one side of the inner wall of the cleaning machine housing. A first cleaning mechanism is slidably connected to the middle of the linear track. A second cleaning mechanism is installed on the cleaning machine housing on one side of the conveying platform. Both of the operating mechanisms include a vertical rod and an operation panel. Angle brackets are rotatably connected to both ends of one side of the vertical rod. One ends of the two angle brackets away from the vertical rod are respectively fixedly connected to both ends of one side of the operation panel. The first cleaning mechanism includes a mounting frame and a first laser cleaning head. The top end of the mounting frame is fixedly connected to the bottom end of the first laser cleaning head. The second cleaning mechanism includes a height frame and a second laser cleaning head. A height block is slidably connected to one side of the height frame. A length arm is fixedly installed on one side of the height block. One end of the length arm is rotatably connected to a direction seat. The direction seat is fixedly connected to the second laser cleaning head. The angle brackets deflect at an angle along the vertical rod to adjust the position of the operation panel. The cleaning personnel of the battery liquid cooling plate can place the cleaning tools on the operation table.

[0007] Preferably, an operation table is hinged to the end opposite to the operation panel. The middle of the vertical rod is fixedly connected to the cleaning machine housing. The operating mechanism is installed on the cleaning machine housing through the vertical rod.

[0008] Preferably, sliding blocks are fixedly installed on both sides of the bottom end of the mounting frame. Both of the sliding blocks are slidably connected to the linear track. The sliding blocks slide along the linear track. During the sliding process of the sliding blocks, the mounting frame is driven to move synchronously. The mounting frame drives the first laser cleaning head to move synchronously. The first laser cleaning head generates a laser beam that irradiates the automotive battery liquid cooling plate. The laser energy is absorbed by the organic and inorganic impurities on the surface. The laser energy absorbed by these impurities heats them to a transient high-temperature state, partially burns them, and makes them gaseous. This process generates a gas plasma region, which represents that the impurities have absorbed the visible laser energy. Utilizing this phenomenon, the impurities on the surface of the automotive battery liquid cooling plate can be removed by laser adsorption. When the laser energy heats the surface impurities, these impurities expand from the surface at a very high speed. This process is called instantaneous expansion and easy ionization. After the impurities are heated and expanded, an airbag ring is formed in the air. Under such conditions, the impurities expand and reach more than twice their volume. At the same time, the impurities also become easy to peel off.

[0009] Preferably, a baffle is fixedly installed on one side of the mounting frame. The baffle blocks the laser generated by the first laser cleaning head from one side.

[0010] Preferably, a motor for driving the height block to slide is fixedly installed at the top of the height frame, and a rotary motor for driving the direction seat to rotate is fixedly installed on the surface of the length arm. The bottom end of the height frame is fixedly connected to the cleaning machine housing. After the motor is powered on and starts, the motor drives the height block to slide along the height frame. During the sliding process of the height block, the height of the second laser cleaning head is adjusted. After the rotary motor is powered on and starts, the rotary motor drives the direction seat to deflect at an angle along the length arm to adjust the angle of the second laser cleaning head. The second laser cleaning head generates a laser beam that irradiates on the battery liquid cooling plate. The laser energy absorbs organic and inorganic impurities on the surface. The laser energy absorbed by these impurities heats them to a transient high-temperature state, partially burns them, and makes them gaseous. This process generates a gas plasma region, which represents that the impurities have absorbed visible laser energy. Using this phenomenon, the impurities on the surface of the automotive battery liquid cooling plate can be removed by laser adsorption. When the laser energy heats the surface impurities, these impurities expand from the surface at a very high speed. This process is called instantaneous expansion and easy ionization. After the impurities are heated and expanded, an airbag ring is formed in the air. Under such conditions, the impurities expand and reach more than twice their capacity. At the same time, the impurities also become easy to peel off.

[0011] Preferably, a stepping motor for driving the first cleaning mechanism to slide is fixedly installed on the cleaning machine housing. After the stepping motor is powered on and starts, the stepping motor drives the first cleaning mechanism to slide along the linear track to adjust the position of the first cleaning mechanism.

[0012] Preferably, one side of the inner wall of the cleaning machine housing is fixedly communicated with a high-pressure hose extending to the outside. One end of the high-pressure hose is fixedly communicated with a high-pressure gas spray hood located on the conveying platform. An external high-pressure gas supply device is connected to the high-pressure hose. After the high-pressure gas supply device transports high-pressure gas to the high-pressure hose, it is finally sprayed out through the high-pressure gas spray hood to clean the airbag ring formed on the surface of the battery liquid cooling plate placed on the conveying platform.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: By setting the first cleaning mechanism and the second cleaning mechanism, the first cleaning mechanism slides along the linear track to adjust the position of the first laser cleaning head, and the height block slides along the height frame and the direction seat deflects at an angle along the length arm to adjust the position of the second laser cleaning head, replacing the traditional friction cleaning of impurities on the surface of the battery liquid cooling plate, avoiding scratches on the surface of the battery liquid cooling plate after cleaning, and extending the service life of the battery liquid cooling plate.
