Screen printing clamp

Abstract

The invention discloses a screen printing clamp which comprises a bearing mechanism and a positioning mechanism, wherein the bearing mechanism comprises a bearing frame and limiting pieces; the bearing frame takes a frame structure and forms a bearing area; the limiting pieces are distributed along the edge of the bearing area and lock a glass screen in a selectable manner; when the glass screen is born in the bearing area, the limiting pieces jointly bear and fix the glass screen; the positioning mechanism comprises a vacuum base and a support piece; the vacuum base takes a hollow structure and forms an airtight cavity; negative pressure is formed in the airtight cavity; the vacuum base is provided with an adsorption area; the adsorption area is provided with a first adsorption hole communicating with the airtight cavity; the support piece goes up and down in a selectable manner; when the bearing frame is born on the support piece, the support piece descends to drive the bearing frameto move towards the vacuum base; the first adsorption hole adsorbs the glass screen on the vacuum base; and the limiting pieces lock the glass screen. The screen printing clamp is simple in structure, can lock the glass screen in a self-adaption manner, is high in fixing precision, can adjust the adsorption intensity and can realize multiple printing through one screen.

Description

technical field [0001] The invention relates to the technical field of silk screen printing, in particular to a screen printing jig for fixing a glass screen for screen printing operation on the glass screen of a mobile phone. Background technique [0002] With the advent of the information age, because electronic products can receive information in real time, people are increasingly dependent on electronic products. As an indispensable information carrier for adults to connect to the outside world, the market demand for mobile phones has become very large. In order to improve the appearance of the mobile phone screen, it is necessary to perform silk screen printing on the glass screen of the mobile phone screen. However, the screen printing fixtures used in the prior art for glass screens are limited by the way of fixing the glass screens, and cannot effectively and accurately fix the glass screens self-adaptively, and often require manual adjustments; At the same time, on...
