Description

A spraying device for the lower cover of new energy vehicles Technical Field

[0001] This utility model relates to the field of automotive painting technology, specifically to a painting device for the lower cover of new energy vehicles. Background Technology

[0002] With the booming development of the new energy vehicle industry, the lower cover of new energy vehicles, as a key protective component of the vehicle's battery system, has its coating quality directly affecting battery safety and vehicle lifespan. The coating must not only meet basic performance requirements such as corrosion resistance and wear resistance, but also achieve a high-quality standard of smooth appearance and uniform color.

[0003] However, traditional spraying devices for the lower cover of new energy vehicles have many technical bottlenecks. On the one hand, the spray gun needs to wait for the coating to be completed before loading and unloading can be done, resulting in a slow speed and indirectly increasing working time. On the other hand, manual cleaning of the spray gun is inefficient and the cleaning effect is difficult to guarantee. Frequent disassembly can also damage the spray gun parts, increasing equipment maintenance costs.

[0004] In summary, it is particularly important to design a spraying device that can perform both spraying and loading / unloading operations simultaneously, while also facilitating the cleaning of the spray gun without damaging it. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems of difficult disassembly and cleaning of spray guns and the inability to load and unload materials simultaneously during the spraying process, as described in the background art.

[0006] Based on the above technical ideas, the technical solution adopted by this utility model is as follows: by setting a movable drum at the bottom of the main body of the device, the movable mechanism is divided into a working area and a loading and unloading area, so that loading and unloading can be carried out at the same time, and the spray gun can be cleaned by the cleaning mechanism, that is, it can be cleaned without disassembly, which also saves water resources.

[0007] A spraying device for the lower cover of a new energy vehicle includes a main body, a movable mechanism on the top of the main body, and a cleaning mechanism on one side of the main body. The movable mechanism includes a movable base, a limiting block, a fixing block, a return spring, a movable block, a rubber block, an insertion shaft, and an adsorption magnet. Insertion shafts are symmetrically distributed on both sides of the movable base, and an adsorption magnet is sleeved in the center of each insertion shaft. The insertion shaft is slidably connected to the main body. The adsorption magnet cooperates with the insertion shaft to ensure that both sides of the movable base are in a stable state.

[0008] Further defining the above technical solution, the connection between the main body of the device and the movable base is a sliding connection. A drive mechanism is also provided above the main body of the device. The drive mechanism is divided into a left-right moving mechanism and a right-up-down lifting mechanism. A spray gun is provided below the drive mechanism, and a spray material box is provided above the spray gun. The lower cover is then sprayed by the cooperation between the main body of the device and the spray gun.

[0009] To further define the above technical solution, a limiting block is connected above the movable base, and a fixing block is connected to the inner side of the limiting block. There are three limiting blocks in total. The movable block is fixed by the cooperation of the fixing block and the limiting block, which facilitates subsequent use.

[0010] Further defining the above technical solution, the cleaning mechanism also includes an air compressor, a transmission pipe, an air nozzle, a connecting rod, and a dust filter. The transmission pipe is connected to one side of the air nozzle, and the air compressor is connected to the top of the transmission pipe. An air filter is also installed inside the air compressor, which allows the air compressor to filter external air.

[0011] Further defining the above technical solution, a dustproof net is connected around the air nozzle, and connecting rods are connected to both sides of the dustproof net. The front and rear sides of the dustproof net are higher than the left and right sides. The connecting rods cooperate with the dustproof net to fix the dustproof net and prevent it from moving.

[0012] Further defining the above technical solution, a reset spring is connected below the fixed block, and a movable block is connected below the reset spring. The movable block and the fixed block form a sliding connection structure through a vertical rod. The movable block and the reset spring cooperate to clamp the lower cover and prevent it from shaking during the spraying process.

[0013] Further defining the above technical solution, the connection between the movable block and the limiting block is a sliding connection, and a rubber block is connected below the movable block. The rubber block has a conical structure, which compresses the lower cover of the arc-shaped structure through the conical rubber block, while avoiding excessive rigid compression that could cause deformation of the lower cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) High working efficiency: The movable base is set inside the main body of the device. The movable base is divided into two different areas by the limiting block. When one area is loading and unloading, the other working area is spraying inside the main body of the device, which ensures that loading and unloading can be carried out at the same time, thus improving working efficiency. Furthermore, the conical rubber clamping avoids deformation of the lower cover caused by rigid clamping.

[0016] (2) High cleaning efficiency: By setting an air nozzle on one side of the main body of the device, after the spraying work is completed, the spray gun moves to the air nozzle and then high-pressure air cleans the spray gun, so that the debris on the surface of the spray gun falls off. The cleaning can be carried out without disassembling the spray gun, while saving water resources and being energy-saving and environmentally friendly. Attached Figure Description

It includes a main body 1, characterized in that a movable mechanism 2 is further provided above the main body 1. The main body 1 is slidably connected to the movable base 200. A drive mechanism 4 is also provided above the main body 1, comprising a left-right moving mechanism and a right-up lifting mechanism. A spray gun 3 is provided below the drive mechanism 4, and a spray material box 5 is provided above the spray gun 3. The main body 1 and the spray gun 3 cooperate to... The lower cover is sprayed. The movable mechanism 2 also includes a movable base 200, a limiting block 201, a fixing block 202, a return spring 203, a movable block 204, a rubber block 205, an insertion shaft 206, and an adsorption magnet 207. The insertion shafts 206 are symmetrically distributed on both sides of the movable base 200. The adsorption magnet 207 is sleeved in the center of the insertion shaft 206. The insertion shaft 206 is connected to the main body 1 of the device by sliding connection. The adsorption magnet 207 cooperates with the insertion shaft 206 to ensure that both sides of the movable base 2 are in a stable state.

[0025] Referring to Figures 1, 3, and 4, in this embodiment of the invention, the movable base 2 can move left and right to allow for simultaneous material loading and spraying. A limiting block 201 is connected above the movable base 2, and a fixing block 202 is connected to the inner side of the limiting block 201. There are three limiting blocks 201 in total. The fixing block 202 cooperates with the limiting blocks 201 to limit and fix the movable block 204, facilitating subsequent use. A return spring 203 is connected below the fixing block 202. A movable block 204 is connected, and the movable block 204 forms a sliding connection structure with the fixed block 202 through a vertical rod. The movable block 204 cooperates with the return spring 203 to clamp the lower cover and prevent it from shaking during the spraying process. The movable block 204 is connected to the limiting block 201 in a sliding connection manner. A rubber block 15 is connected below the movable block 204. The rubber block 15 has a conical structure. The conical rubber block 15 compresses the arc-shaped lower cover while avoiding excessive rigid compression that could cause deformation of the lower cover.

[0026] Referring to Figures 1 and 2, in this embodiment of the invention, a cleaning mechanism 6 is provided on one side of the main body 1 of the device. The cleaning mechanism 6 also includes an air compressor 601, a transmission pipe 602, an air nozzle 603, a connecting rod 604, and a dustproof net 605. The transmission pipe 602 is connected to one side of the air nozzle 603, and the air compressor 601 is connected above the transmission pipe 602. An air filter is also provided inside the air compressor 601, which allows the air compressor 6 to filter external air. A dustproof net 10 is connected around the air nozzle 603, and a connecting rod 9 is connected to both sides of the dustproof net 10. The front and rear sides of the dustproof net 10 are higher than the left and right sides. The connecting rod 9 is used to cooperate with the dustproof net 10 to fix the dustproof net 10 and prevent the dustproof net 10 from moving.

[0027] Working principle: First, place the lower cover to be sprayed from the front and rear sides above the movable base 2, and then manually push it to the center of the movable base 2. At this time, the lower cover contacts the conical rubber block 15. The lower cover then squeezes the rubber block 15, so that the rubber block 15 is above the lower cover. Then, the return spring 203 drives the rubber block 15 to adhere to the upper part of the lower cover, fixing the lower cover. Then, push the limit block 201, so that it drives the movable base 2 to move into the inside of the device body 1, until the insertion shaft 206 on one side of the movable base 2 is inserted into the inside of the device body 1, and the magnet 207 attracts the magnet to prevent movement. Then, the drive mechanism 4 drives the spray gun 3 to move continuously to spray the lower cover. After the spraying work is completed, move in the opposite direction and repeat the above steps.

[0028] As described above, after the spraying work is completed, the drive mechanism 4 moves the spray gun 3 above the air nozzle 603, and then turns on the air compressor 6. Air passes through the transmission pipe 602 and is sprayed out from the air nozzle 603, spraying out impurities from the surface of the spray gun 3. After cleaning, the spray gun 3 is reset. After long-term use, push the dust screen 10 to move it toward the connecting rod 9 on one side, so that the other side is disengaged from the connecting rod 9. Then move it in the opposite direction so that the side that was moved is also disengaged from the connecting rod 9. The inside of the dust screen 10 can then be cleaned. It should be noted that the drive mechanism 4 moves the spray gun 3 left and right and up and down, which is basic information known to those skilled in the art. It is completely existing technology and very mature. Therefore, it is only described in the figure.

[0029] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
