Description

Technical Field

[0001] This utility model relates to the field of glass stress relief technology, and more specifically, to a glass edge stress relief device. Background Technology

[0002] Electronic substrate glass is a special type of glass used in applications such as electronic components, flat panel displays, and solar photovoltaic modules. It has advantages such as excellent flatness and transparency, low coefficient of thermal expansion, excellent electrical insulation properties, and chemical stability.

[0003] To ensure the excellent properties of electronic substrate glass, stress relief is required during the manufacturing process through heat treatment. Existing technologies typically employ annealing for stress relief. However, for glass substrates with thicker edges, varying cooling rates lead to different stress levels, necessitating localized heating or cooling. For example, patent CN113735426A discloses a glass edge stress relief device that uses a rotating flexible wiping element to uniformly cool the glass edge, ensuring effective edge stress relief. However, while the wetted flexible wiping element provides localized cooling, it relies on the instantaneous vaporization of the liquid, requiring repeated immersion, resulting in a short lifespan, low cooling efficiency, and poor stress relief.

[0004] Based on the above description, there is an urgent need for a stress relief device with excellent stress relief effect on the glass edge. Utility Model Content

[0005] The purpose of this utility model is to provide a glass edge stress relief device, which aims to solve the technical problem that the existing method of immersion wiping to promote cooling when the glass edge is thick has a narrow range of application and requires frequent immersion wiping, resulting in poor stress relief effect.

[0006] The embodiments of this utility model are achieved through the following technical solutions:

[0007] A glass edge stress relief device includes a pair of housings and a support assembly; the pair of housings are disposed opposite each other at both ends of the support assembly; each pair of housings has a strip-shaped opening on one side; a cover plate is slidably connected to each housing; the cover plate covers the strip-shaped opening; and a heating assembly is provided inside each housing.

[0008] Preferably, the support assembly includes multiple connecting plates and multiple connecting strips; the multiple connecting plates are connected between a pair of housings via the multiple connecting strips.

[0009] Preferably, the cover plate has a pair of slide bars on the side near the box body; the pair of slide bars are disposed opposite each other at both ends of the strip-shaped opening; the box body has a groove near the strip-shaped opening for the slide bars to be inserted.

[0010] Preferably, the bottom of the box body is provided with a connecting hole plate; the top of the connecting hole plate is recessed with a positioning groove for the end of the slide bar to be inserted.

[0011] Preferably, the bottom of the box body is provided with a connecting hole plate; the top of the connecting hole plate is recessed with a strip-shaped limiting groove; the bottom of the cover plate is provided with a strip block embedded in the strip-shaped limiting groove.

[0014] Preferably, both the blower assembly and the exhaust assembly are connected to a cooling assembly.

[0015] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0016] This invention employs a box-like structure to isolate the edges of the glass substrate. The glass substrate is fed into the box through a strip-shaped opening, and then a cover slides down for further isolation. A heating assembly further heats the interior of the box. Because heating takes place within the box and is shielded by the cover, heat retention is excellent, facilitating efficient and precise annealing of the glass substrate edges. This method is time-saving, labor-saving, simple to operate, and provides excellent stress relief. Furthermore, a pair of boxes can be used to simultaneously stress-treat both sides of the glass substrate, suitable for glass substrates with varying edge thicknesses. A support assembly supports the main body of the glass substrate, ensuring that the edges are placed horizontally within the box for uniform stress treatment. Attached Figure Description
