Description

Glass cover plate splitting jig Technical Field The utility model relates to the technical field of glass cover plate splitting, in particular to a glass cover plate splitting jig. Background At present, glass cover plates with the characteristics of high transparency, high strength, scratch resistance, impact resistance and the like, particularly glass cover plates with raised structures, are adopted on intelligent products including mobile phone cameras, intelligent wearing, intelligent household appliances and the like. In the production of glass cover plates, a plurality of glass cover plates are usually formed on a whole glass structure by a mould pressing technology, and then a plurality of glass cover plates are obtained on the whole glass structure by a splitting technology, wherein the conventional splitting technology is to form a plurality of glass cover plates with required sizes by laser cutting. However, the conventional breaking jig is easy to break and wear the glass cover plate due to stress concentration in the breaking process, and affects the quality and production efficiency of the glass cover plate. Disclosure of utility model In view of the above problems, an object of the present utility model is to provide a glass cover plate breaking jig capable of preventing a glass cover plate from being broken and worn during breaking. The utility model provides a glass cover plate splitting jig which comprises a lower pressing plate, an upper pressing plate, an elastic piece and a plurality of splitting bosses, wherein a limiting groove is formed in the middle of the lower pressing plate, a plurality of hollow grooves which are distributed at intervals are formed in the bottom of the limiting groove, the hollow grooves penetrate through the lower pressing plate, the surface of the upper pressing plate facing the lower pressing plate is provided with a supporting boss, the supporting boss is provided with the plurality of splitting bosses which are distributed at intervals, the splitting bosses are arranged in one-to-one correspondence with the hollow grooves, one end of the elastic piece is arranged on the supporting boss, the other end of the elastic piece extends towards the lower pressing plate, and the height of the elastic piece is larger than that of the splitting boss. Further, the lobe boss is provided with an empty avoiding groove. Further, the projection area of the supporting boss on the limiting groove is smaller than the area of the limiting groove. Further, the elastic piece is any one of a spring, a foam pad and a rubber pad. Further, the elastic piece is a stainless steel spring. Further, the glass cover plate splitting jig further comprises an abutting block, and the abutting block is fixed on one side, facing the lower pressing plate, of the stainless steel spring. Further, the elastic coefficient of the stainless steel spring is in the range of 0.5N/mm-2N/mm. Further, the number of the elastic pieces is four and the elastic pieces are uniformly distributed around the supporting boss. Further, the upper pressing plate and the lower pressing plate are made of bakelite. Further, four corners of the limiting groove are provided with avoiding grooves. Compared with the prior art, the utility model has the beneficial effects that: (1) Through setting up the elastic component between holding down plate and top board, and the surface of the lobe of a leaf boss that the elastic component protrusion is used for bearing the glass apron makes holding down plate and top board when the lid, and the elastic component provides certain buffering for the glass apron, prevents that the glass apron from being broken and wearing and tearing. (2) Through set up the void avoidance groove on the lobe of a leaf boss that bears the weight of glass apron, make the protruding structure on the glass apron can stretch into the void avoidance inslot, avoid protruding structure to receive stress, finally lead to the glass apron to break.
