Description

Technical Field

[0001] The utility model relates to the field of automobile parts processing equipment, in particular to a full-angle automatic cotton sticking device. Background Art

[0002] During the automobile manufacturing process, foam needs to be pasted on the edge of the radiator deflector to achieve functions such as heat insulation, sound insulation, and shock absorption, thereby improving the comfort and safety of the car. However, the existing pasting method is mainly manual, which has many disadvantages.

[0003] First, it is difficult to ensure the accuracy of the pasting position when pasting manually. Due to the complex shapes, sizes and structures of exterior trims, it is difficult to accurately attach the foam to the predetermined position when pasting it manually, which will not only affect the heat insulation and sound insulation effects of the foam, but also may cause gaps between the foam and the exterior trim, reducing the overall sealing and aesthetics of the car.

[0004] Secondly, manual pasting is inefficient. On large-scale automobile production lines, manual pasting of foam requires a lot of manpower and time. Operators need to cut, position and paste the foam to the edge of the exterior trim, which is a cumbersome and time-consuming process. In a high-intensity working environment, manual operation is also prone to fatigue, further reducing work efficiency, seriously affecting the overall work efficiency of foam pasting, and becoming a bottleneck in the automobile production process.
