Description

Technical Field

[0001] This utility model relates to the field of paint spraying technology, specifically to an automated paint spraying device for automobiles. Background Technology

[0002] An automobile is a vehicle that is powered by its own energy and can move without relying on tracks or electricity. The production of an automobile requires the separate processing of multiple parts, which are then assembled or welded together to create the automobile. After the structural processing of some automobile parts, such as doors, frames, hoods, and trunk lids, they need to be painted.

[0003] Chinese Patent Publication No. CN114192317A discloses a painting device for automotive parts, relating to the field of automotive parts processing. The device includes a main body and a motor. A cabinet is connected to the back of the main body, and a drying assembly is installed inside the cabinet. A cabinet door is connected to the back of the cabinet. A dustproof plate is connected to the top of the main body, and a gantry frame is connected inside the dustproof plate. A feed inlet is connected to the top of the gantry frame. This invention utilizes a storage trough, a support guide frame, a cleaning frame, a motor, gears, a rack, a drain trough, a dustproof curtain, and a dustproof plate. The dustproof curtain and dustproof plate work together to prevent excessive paint scattering during painting of automotive parts, thus avoiding pollution and waste. The arrangement of two motors, two gears, and two racks facilitates the movement of the cleaning frame and the placement plate. The cleaning frame facilitates the scraping off of paint adhering to the inner wall of the dustproof plate. The paint is then collected and discharged through the storage trough, drain trough, and guide trough, effectively reducing environmental pollution and paint waste during painting.

[0004] However, the above technical solution has the following defects: the above-mentioned automotive parts painting device sprays paint through the spray head on the gantry, but the spray direction of the spray head is horizontal, which makes the paint spraying of parts with more complex shapes less uniform and inconvenient to use.
