Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts assembly, and particularly relates to a double-station automatic glue and cotton pasting device. Background Art

[0002] For automobile left spoilers, right spoilers, etc., their surfaces need to be pasted with cotton to achieve functions such as heat insulation, sound insulation, and shock absorption, so as to improve the comfort and safety of the automobile. However, the existing pasting methods are mainly manual operations, and such methods have many disadvantages as follows: First, it is difficult to ensure the accuracy of the pasting position by hand. Due to the complex shape of the automobile spoiler and the differences in the size and structure of spoilers of different vehicle models, it is very difficult for manual workers to accurately attach the foam to the predetermined position when pasting the foam. This will not only affect the heat insulation and sound insulation effects of the foam, but may also cause gaps between the foam and the spoiler, reducing the overall airtightness and aesthetics of the automobile; Second, the efficiency of manual pasting is low. On a large-scale automobile production line, manually pasting foam requires a large amount of manpower and time. The operator needs to cut, position, and paste the foam to each position of the spoiler one by one. This process is cumbersome and time-consuming. In a high-intensity working environment, manual operation is also prone to fatigue, further reducing the work efficiency, seriously affecting the overall work efficiency of pasting the foam, and becoming a bottleneck link in the automobile production process.

[0003] In summary, there is an urgent need for an automatic cotton pasting device that can improve the accuracy of the pasting position and work efficiency to meet the strict requirements of modern automobile manufacturing for production efficiency and product quality. Summary of the Invention

The pointed end of the lower pressing block extends towards the glue - sticking wheel, and a gap for the tape to pass through is formed between the two. On the glue - sticking frame, there is also a second driving cylinder and a pressure - glue wheel mounted on the second driving cylinder. The pressure - glue wheel is located on one side of the glue - sticking wheel, and they are on the same horizontal plane. The shearing end of the scissor component is located between the pressure - glue wheel and the glue - sticking wheel.

[0022] The present invention with the above - mentioned features: Through the coordinated action of each component, the movement is smooth, the tape is stuck flat, and the glue - sticking length can be fixed, realizing fully automatic glue - sticking and improving the glue - sticking accuracy. The mounting plate in the glue - sticking component is rotatably mounted on the glue - sticking frame. Under the drive of the first driving cylinder, the glue - sticking wheel presses down to firmly stick the tape on the workpiece. The first driving cylinder intermittently presses down or lifts the glue - sticking wheel to achieve fixed - length glue - sticking. The second driving cylinder can press down the pressure - glue wheel to press the tape, preventing the tape from shaking or the already - stuck part from peeling off the product, ensuring the fixed - length accuracy of tape - sticking and facilitating the scissor component to quickly cut the tape.

[0023] A further setting of the present invention is that the scissor component includes a slide - table cylinder, a connecting plate, and a pneumatic scissor. The connecting plate connects the output end of the slide - table cylinder and the pneumatic scissor at the same time.

[0024] The present invention with the above - mentioned features: By setting the slide - table cylinder to control the moving position of the pneumatic scissor, the telescopic movement of the pneumatic scissor is realized, avoiding interference with material conveying.
