Description

Technical Field

[0001] The utility model relates to the technical field of watch glass cover plate preparation equipment, and specifically, to a heat bending and film sticking integrated structure for glass cover plates. Background Technique

[0002] With the continuous development of the smart watch and traditional watch markets, consumers' requirements for the appearance, durability, and waterproof performance of products are increasing day by day. The cover plate part of a watch is generally made of a glass cover plate material. Since the glass cover plate of a watch is generally of an arc structure, when processing the glass cover plate, a heat bending forming operation needs to be performed on the glass cover plate. In addition, in order to improve the waterproof effect, a film sticking protection operation is usually also carried out on the surface of the glass cover plate.

[0003] Traditional processing methods for watch glass cover plates often require two steps of heat bending forming and film sticking protection respectively. This not only increases the processing cost, but also may cause problems such as damage to the edges of the glass cover plate or non-fitting of the film due to multiple treatments. At present, in order to achieve the effect of portable heat bending and film sticking operations for glass cover plates, a corresponding heat bending and film sticking integrated structure for glass cover plates is usually used. There are many types of heat bending and film sticking integrated structures for glass cover plates on the market, but most of the heat bending and film sticking integrated structures for glass cover plates use heat pressing rollers for heat pressing operations. However, since most heat pressing rollers are columnar, it is difficult to ensure that the glass cover plate is heat bent into a shape that conforms to the appearance of the watch, which affects the use and preparation effects and brings inconvenience to users. In view of this, we have proposed a heat bending and film sticking integrated structure for glass cover plates. Content of the Utility Model
