Description

Technical Field

[0001] This utility model relates to the technical field of coating spraying equipment, specifically an automatic spraying device for automotive sealing strip coating. Background Technology

[0002] Automotive sealing strip coating agent is an auxiliary material used to enhance the surface performance of sealing strips, typically applied as a primer. Its core function is to improve the adhesion between the sealing strip and paint or adhesive by wetting the substrate surface, addressing the issue of weak adhesion for low surface energy materials. This coating agent can be applied by spraying or brushing to form a specific film thickness, improving the sound insulation, water resistance, and shock absorption performance of the sealing strip, while also enhancing its adhesion to the vehicle body and preventing delamination. In adhesive or painting processes, it significantly improves product reliability and is a key auxiliary material ensuring the long-term stable operation of sealing strips.

[0003] Utility model patent CN208643017U discloses a primer spraying device, relating to the field of decoration equipment technology. This primer spraying device includes a spraying device housing, a base plate welded to the lower surface of the housing, a support column fixedly connected to the lower surface of the base plate, and a roller movably connected to the end of the support column away from the base plate. A suction box is installed inside the spraying device housing, with a suction port on the inner bottom wall of the suction box. A water pump is fixedly connected to the right side of the spraying device housing. This primer spraying device uses a motor-driven shaft to rotate a stirring blade, continuously agitating the primer within the spraying device, thus preventing the primer from curing. This effectively solves the problem of current primer spraying devices where the primer easily cures, leading to clogging and damage to the spraying device.

[0004] However, common coating spraying devices require cleaning impurities from the spraying area before spraying, and after spraying, the coating is distributed in granular form on the sprayed area, which is not uniform. Therefore, an automatic coating spraying device for automotive sealing strips is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic spraying device for automotive sealing strip coating agents, which has advantages such as improved spraying efficiency and coating uniformity, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0027] Specifically, during the movement of the spray box 2, the positioning camera 10 remains in the direction of movement, and the two rotating motors 5 drive the cleaning brush 7 and the evenly distributed brush 8 to rotate. The cleaning brush 7 rotates and first contacts the spray path to brush away the impurities on the spray area. The nozzle 4 sprays the coating agent out, and finally the evenly distributed brush 8 rotates to spread the coating agent evenly.

[0028] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, a first slider 11 is slidably installed on the inner wall of the first mounting groove 12, and the mounting base box 1 is fixedly installed on the bottom of the first slider 11. A second slider 13 is slidably installed on the inner wall of the second mounting groove 14, and the first mounting groove 12 is fixedly installed on the bottom of the second slider 13.

[0029] In this system, a mounting plate 15 is fixedly installed on the top of the second mounting groove 14; a first guide rod 16 is fixedly installed on the inner wall of the first mounting groove 12, and the first guide rod 16 slides through the first slider 11; a first screw 17 is rotatably installed on the inner wall of the first mounting groove 12, and the first screw 17 is threadedly connected to the first slider 11; a first motor 18 is fixedly installed on one side of the first mounting groove 12, and the output shaft of the first motor 18 is fixedly connected to one end of the first screw 17.

[0034] One end of the output pipe 29 is fixedly installed with a connecting pipe 30, which is connected to the spray pipe 3. A controller 31 is fixedly installed on the top of the mounting plate 15. The spray pump 28 draws the coating agent from the coating agent tank 22 and delivers it to the spray pipe 3 through the connecting pipe 30, and sprays it out through the nozzle 4.

[0035] Specifically, the controller 31 controls the first motor 18 and the second motor 21 to work, driving the nozzle 4 to move according to the spraying path. The positioning camera 10 identifies the spraying path and controls the reversing motor 9 to work, so that the positioning camera 10 remains in the moving direction, and the cleaning brush 7 always remains in front of the nozzle 4.

[0036] The working principle of the above embodiment is as follows: During the movement of the spray box 2, the positioning camera 10 is kept in the moving direction, and the two rotating motors 5 drive the cleaning brush 7 and the uniform brush 8 to rotate. The cleaning brush 7 rotates and first contacts the spraying path to brush away the impurities on the spraying area. The nozzle 4 sprays the coating agent out.
