However, the existing pasting method is mainly operated manually, which has the following disadvantages: First, it is difficult to ensure the accuracy of the pasting position when pasting manually. Due to the complex shape of the car spoiler and the differences in the size and structure of the spoiler of different models, it is difficult to accurately attach the foam to the predetermined position when pasting the foam manually, which not only affects the heat insulation and sound insulation effect of the foam, but also may cause a gap between the foam and the spoiler, reducing the overall sealing and aesthetics of the car; secondly, the efficiency of manual pasting is low. On a large-scale automobile production line, manual pasting of foam requires a lot of manpower and time. The operator needs to cut, position and paste the foam one by one to each position of the spoiler. This process is cumbersome and time-consuming. In a high-intensity working environment, manual operation is also prone to fatigue, which further reduces work efficiency, seriously affecting the overall work efficiency of pasting foam, and becoming a bottleneck in the automobile production process.
