A super-size film blanking fixture

Abstract

The invention discloses an ultralarge-size FILM blanking jig. The ultralarge-size FILM blanking jig comprises an outer frame and an inner frame arranged on the inner side of the outer frame. A body ofthe outer frame is of a rectangular framework structure. Four bottom supporting plates of a rectangular structure are symmetrically arranged on the lower end faces of the left side and the right sideof the outer frame. Four suspension rings are symmetrically arranged on the upper end faces of the left side and the right side of the outer frame. A plurality of side supports and automatic clampingmechanism installed on the side edges of the inner frame in a matched mode can make corner pressing action relative to a FILM plate on a flexible cushion plate at the upper end of the inner frame atthe same time, the pressing action and pressure are both kept coincident, the pressing position distribution is uniform, forces on the end face of the FILM plate in all direction can be balanced, andthe FILM cannot be deformed in the discharging and carrying processes; and the FILM plate is limited and fixed on the upper end face of the flexible cushion plate through limiting stop edges of the upper ends of the side supports, electric cylinders on the automatic clamping mechanisms drive elastic pressing plates to lock the FILM plate onto the upper end face of the inner frame, and the FILM plate is prevented from slipping off in the clamping process.

Description

technical field [0001] The invention relates to the technical field of auxiliary tooling, in particular to an oversized FILM blanking jig. Background technique [0002] With the development of touch screen technology, touch screens are used in more and more products. The size of touch screens is developing in two directions: miniaturization and giantization. In the production of giant touch screens, the blanking of super-sized FILM is one of them. A necessary process of the prior art, manual blanking is usually used in the prior art, but it still has the following disadvantages in actual operation: [0003] 1. Because the FILM sheet is relatively thin and easy to bend, the FILM sheet is easily deformed or crushed due to unbalanced strength during manual operation, resulting in the scrapping of the FILM sheet; [0004] 2. Because the surface of the FILM sheet is relatively smooth, it is not easy to grasp, and it will fall off due to hand slipping during the lifting process, ...

AI Technical Summary

Problems solved by technology

[0003] 1. Because the FILM sheet is relatively thin and easy to bend, the FILM sheet is easily deformed or crushed due to unbalanced strength during manual operation, resulting in the scrapping of the FILM sheet;

[0004] 2. Because the surface of the FILM sheet is relatively smooth, it is not easy to grasp, and it will fall off due to hand slipping during the lifting process, resulting in damage to the FILM sheet;

[0005] 3. Because the FILM is thin, the edges are relatively sharp. When grasping by hand, it is easy to cut the palm and cause work-related accidents.
