AI Technical Summary
In existing technologies, the leather-covered area on the cover surface is not thoroughly treated, resulting in weak adhesion. Furthermore, flame treatment can easily cause the cover to deform. Fluorination treatment is time-consuming and wasteful, and linear plasma treatment is uneven, failing to meet the demands of rapid production.
The vacuum plasma cleaning machine uses a housing and is controlled by positive and negative electrode components and a control panel to clean the surface of the cover, ensuring that the adhesive is fully activated and improving the peeling force of the leather.
This ensures the leather on the cover is firmly bonded, preventing cover deformation and tear lines, meeting the needs of rapid production, and reducing material waste and transportation costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive airbag technology, and in particular to a cleaning device for a cover surface covered with leather. Background Technology
[0002] There is a driver's safety airbag module cover that is covered with leather. Because the TPO plastic particles used in the injection molding of the cover have very low surface tension and poor adhesion after injection molding, it is necessary to treat the leather-covered area of the cover surface. At the same time, the adhesive used is an environmentally friendly water-based adhesive. The adhesive is first applied to the cover body and the leather, dried, and then activated by a certain temperature. Pressure is applied to firmly bond the leather to the cover surface. The operation method uses a hot melt machine and a hot press fixture to automatically perform hot pressing, activation, and bonding. Although the adhesive between the cover and the leather is fully activated, the area of the cover to be covered with leather is not fully treated or cleaned, resulting in no leather adhering to the cover surface. The adhesion is not firm, and the leather and adhesive detach from the cover, which does not meet the requirements.
[0003] Existing surface treatment or cleaning methods for covers:
[0004] 1. The areas of the cover surface that need to be covered with leather are flame-treated with a flame gun. After flame treatment, the peeling force of the leather on the cover surface is enhanced and the leather is firmly adhered. However, due to the excessively high temperature of the flame and the uncontrollable time and distance of the flame treatment, some parts of the cover melt due to high temperature and some parts of the cover are deformed. The tear lines on the surface are obviously raised, affecting the overall appearance and size of the cover and failing to meet the requirements of the cover surface treatment.
[0005] 2. The cover is directly fluorinated. The fluorinated cover can cover leather that meets the requirements for peel strength, appearance and size. However, the fluorinated cover has a shelf life of 1 month. It needs to be fluorinated by a professional cover fluorinating manufacturer. The round-trip transportation cycle and fluorination production cycle are about 15 days in total. The material waiting period is very long, which is not conducive to rapid production scheduling. In addition, the batch of fluorinated covers is large. If the covers are not used after fluorination, they will have exceeded the expiration date, resulting in material waste. At the same time, the cost of fluorination and round-trip transportation is not low. Therefore, for production enterprises that need to react quickly, fluorination is not the optimal surface treatment method for covers.
[0006] 3. The surface of the cover was treated with linear plasma, but the treatment of the finishing area was incomplete. Due to the different heights of the curved surface of the cover, the peel strength of the leather on the treated cover surface was only sufficient in some areas, while the peel strength of most areas was low and did not meet the requirements.
[0007] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

The vacuum plasma cleaning chamber 10 contains several layers of positive and negative electrode components 20 for placing several cover bodies 1. In this embodiment, each layer of positive and negative electrode components 20 includes a positive electrode plate 21 disposed within the vacuum plasma cleaning chamber 10 and above several cover bodies 1, and a negative electrode plate 22 slidably disposed within the vacuum plasma cleaning chamber 10 for placing several cover bodies 1. Specifically, there are four layers of positive and negative electrode components 20, arranged sequentially from top to bottom. The negative electrode plate 22 is movably disposed on top of another positive electrode plate 21 and can be pushed back and forth on the positive electrode plate 21.

The oxygen tank is then connected, and the vacuum plasma cleaning machine chamber 10 is started. The cover body 1 is automatically cleaned according to the set parameters. After cleaning, the door is opened, the cover body 1 is clamped against the wall, and the cover body 1 is taken out. It is then allowed to cool naturally to room temperature. The cleaned cover body 1 is then transferred to the coating production line for the next process operation.
