Abstract

The invention discloses a tempering fixture and its rack, comprising teeth and tooth slots located between two adjacent teeth, the tooth slots are used for inserting glass sheets to be tempered, and the width direction of the tooth valleys of the tooth slots An expansion margin is left; the expansion margin corresponds to the maximum difference between the expanded thickness of the glass sheet to be tempered and the expanded width of the tooth valley during the tempering process. During the tempering process, the glass sheet to be tempered is placed in the tooth slot of the rack corresponding to the tempering fixture. Since the width direction of the tooth valley of the tooth slot has an expansion allowance, and the expansion allowance corresponds to the tempering treatment The maximum difference between the expanded thickness of the glass sheet to be tempered and the expanded width of the tooth valley, so the edge of the glass plate to be tempered will not be squeezed with the edge of the tooth valley, and the above rack structure can be used to avoid Edge chipping and cracking problems are easy to occur when tempering with tempering fixtures.

Description

Technical field

[0001] The present invention relates to the field of glass temperance, and more particularly to a tempered fixture and a rack thereof. Background technique

[0002] The tempered glass refers to a glass having a compressive stress, also known as reinforcing glass, and reinforcing the glass by tempered method to obtain a tempered glass. Among them, electronic touch screen temperance is one of the main applications of tempered glass.

[0003] The tempering process of the electronic touch screen is typically placed on the tempered fixture, and then the tempered fixture connecting glass is placed in a corresponding tempered environment for temperate treatment. The tempered fixture is generally in a curly, and a plurality of parallel arranged racks are provided, and the glass sheet to be tempered is inserted into the tooth groove of the rack.

[0004] In general, in order to ensure the stability of the glass sheet inserted in the tempered fixture, the width of the corre...
