Problems solved by technology

However, such a design still cannot meet the design trend of four-sided curved glass. When the film is thermoformed, it is still prone to wrinkles at the corners and bends, making it difficult to form.

Embodiment Construction

[0029] The jig structure 100 of this embodiment can be used for thermoforming a film, such as four-curved surface thermoforming. For example, the film base material that can be used for thermoforming processing can be a material with low dielectric constant, high light transmission and other properties suitable for touch sensing films, such as polyethylene terephthalate (PET), Cycloolefin polymer (COP), and polymethyl methacrylate (PMMA), etc.

[0030] Such as figure 1 and figure 2 As shown, in some embodiments, the jig structure 100 mainly includes a main body 110 and a spacer 120 . The internal shape and size of the main body 110 match the shape of the film to be formed. The main body 110 mainly includes a bottom plate 112 and a first side wall 114 , wherein the bottom plate 112 may have a square or rectangular plate-like structure. The first side wall 114 is erected on the edge of the bottom plate 112 and surrounds the bottom plate 112 in a peripheral manner. The mate...

Abstract

A fixture structure is described. The fixture structure includes a main body and an auxiliary pad. The main body includes a bottom plate and a first sidewall. The first sidewall is disposed on an edge of the bottom plate, and there are four first chamfered edge portions formed between the first sidewall and the bottom plate. The first sidewall has four arc corners. The auxiliary pad includes a second sidewall and an extension portion. The second sidewall is connected to a top surface of the first sidewall, and an inner side surface of the second sidewall aligns with an inner side surface of the first sidewall. The second sidewall has four second chamfered edge portions disposed on the inner side surface of the second sidewall, and four arc indentations correspondingly adjacent to the arc corners and located outside of the corresponding arc corners respectively. The extension portion extends a top of the second sidewall toward an outer of the second sidewall.

Description

technical field [0001] The present invention relates to a jig, and in particular to a jig structure capable of four-sided curved thermoforming. Background technique [0002] In order for the film to be bonded to the four-curved glass, the film must be thermoformed. However, the design trend of today's four-sided curved glass is small curvature and large bending angle, and under this trend, the current thermoforming process is not easy to shape the four corners of the film. [0003] The design of the thermoforming jig for the film will be made according to the shape to be formed. At present, there is a proposed technology, which is to install gaskets on the top of the original jig to increase the height of the overall side wall of the jig structure, so as to increase the contact area of ​​the film with the corner of the jig structure during thermoforming. However, such a design still cannot meet the design trend of four-sided curved glass. When the film is thermoformed, it ...
