Description

Technical Field

[0001] This application relates to the field of bonding equipment technology, and in particular to a bonding device and method for automotive metal horn grille films. Background Technology

[0002] Currently, there are three main methods for bonding speaker grilles: double-sided adhesive, liquid adhesive, and full-surface hot-melt bonding. Double-sided adhesive weakens after high and low temperature storage, and the small bonding area can easily lead to mesh delamination. When applying liquid adhesive, it is easy for the adhesive to overflow into the side holes and onto the outer surface, causing dust to stick to the side holes and dirt to the surface. As for full-surface hot-melt bonding, conventional hot-melt mesh is heat-melted around the perimeter (the heat-melting temperature is as high as 200℃, and the mesh will deform and melt when preheated. Sufficient area of ​​hot-melt mesh is reserved around the holes, and the mesh is pulled around the perimeter to ensure that the mesh is in a relatively bonded state). In daily production, speaker grilles often utilize film lamination technology to prevent external dust or particles from entering the bonding surface with the mesh fabric, affecting the overall gloss and lifespan of the speaker grille. However, film lamination is usually done manually and requires the assistance of large machinery such as laminating machines. This requires a lot of supporting and auxiliary equipment, but the speed and efficiency are not high. Air bubbles are also generated during the lamination process, resulting in poor lamination quality in some areas. In addition, defoaming equipment is needed to remove the bubbles, which greatly increases costs and time. Summary of the Invention

[0003] To improve the aforementioned problems of poor bonding quality and high cost, this invention provides a film bonding device and method for automotive metal horn grilles.

Vacuum adsorption technology can be used to fix the mesh cover shell, and during lamination, the mesh cover shell and film can be brought close to each other and pressed for a period of time, resulting in a tighter bond. After lamination is completed, the mesh cover shell and film can be automatically rolled to defoam, improving the lamination quality and reducing equipment costs and time.

The push rod is slidably connected to the housing, and both ends of the push rod extend to the outside of the housing, with the bottom end of the push rod fixedly connected to the carrier plate.

[0013] Based on the above technical features, the push rod can move up and down inside the housing.

[0015] Based on the above technical features: after starting the vacuum pump, the vacuum suction plate can be vacuumed using the pressure-lifting flexible hose, and the speaker grille housing can be firmly adsorbed and fixed onto the plate using the vacuum suction holes.

[0016] As a preferred embodiment of the automotive metal horn mesh film bonding device of the present invention, the film defoaming assembly includes a lower pressing seat and a threaded screw rotatably disposed inside the lower pressing seat. A second forward and reverse motor is installed on one side of the lower pressing seat. The output shaft end of the second forward and reverse motor is fixedly connected to the threaded screw. A sliding groove penetrating the lower pressing seat is opened on its surface. A threaded sleeve is slidably engaged on the sliding groove.

During the pressing process, the spring can be compressed.

[0022] S104: As the carrier plate descends, it can move the top rod and the pressure film defoaming component at the top of the top rod down together, and make the film and the speaker mesh housing gradually approach each other until they are completely bonded. After the bonding is completed, the clamp is opened and the film is released.

[0023] S105: Start the second forward and reverse motor and drive the screw to rotate. At this time, the defoaming roller in the clamp can contact the surface of the film and use the defoaming roller to roll back and forth on the film and the speaker mesh housing to eliminate air bubbles in the film and the speaker mesh housing. At this time, turn off the vacuum pump and take out the laminated speaker mesh housing to complete the entire lamination work.

[0024] In summary, the present invention has at least one of the following beneficial effects:

[0025] Compared to general laminating machines, the device of this application is smaller in size and does not require any other auxiliary equipment.
