Cell phone cover plate screen printing device

Abstract

The invention relates to a cell phone cover plate screen printing device. The cell phone cover plate screen printing device comprises a screen printing base plate installed on the surface of a screenprinting machine working table and hollowed out in the upper surface and the peripheral surface. A plurality of first clamping plates and second clamping plates are inserted in the hollowed-out surfaces of the front end and the rear end of the screen printing base plate. The first clamping plates and the second clamping plates are matched with each other. The tail end of each first clamping plateand the tail end of each second clamping plate each penetrate out of the end face of the screen printing base plate. A first limiting plate and a sitting wall are closely placed in a gap between eachfirst clamping plate and the corresponding second clamping plate. The middle of the upper end of each first limiting plate and the middle of the upper end of each second limiting plate are each provided with a limiting groove. The two sides of the upper end of each first limiting plate and the two sides of the upper end of each second limiting plate are each fixedly provided with the correspondingsitting wall clamped on the surface of the corresponding first clamping plate or the corresponding second clamping plate. The cell phone cover plate screen printing device can be used multiple timesin combination, the work efficiency is greatly improved, the scratch and damage phenomenon probably happening during multiple times of taking can be reduced, and the screen printing success probability is increased.

Description

technical field [0001] The invention belongs to the technical field of glass screen printing technology, and in particular relates to a mobile phone cover screen printing device. Background technique [0002] Judging from the current screen printing methods of mobile phone covers, most of the screen printing of mobile phone covers are fixed on the surface of the screen printing machine, and printed one by one by the machine. Most of the positioning methods use limit grooves or vacuum suction cups. However, the use of vacuum suction cups is costly and difficult to maintain. The tanks are often connected to the silk screen base, and the method of printing one piece at a time is not suitable for the high-efficiency mode of in-factory operations; [0003] In the mobile phone cover screen printing device disclosed in the patent document CN201620971059.X, it solves the problem of low printing efficiency by setting up multiple processing stations, and also sets up a pick-up hole to...

[0002] Judging from the current screen printing methods of mobile phone covers, most of the screen printing of mobile phone covers are fixed on the surface of the screen printing machine, and printed one by one by the machine. Most of the positioning methods use limit grooves or vacuum suction cups. However, the use of vacuum suction cups is costly and difficult to maintain. The tanks are often connected to the silk screen base, and the method of printing one piece at a time is not suitable for the high-efficiency mode of in-factory operations;

[0003] In the mobile phone cover screen printing device disclosed in the patent document CN201620971059.X, it solves the problem of low printing efficiency by setting up multiple processing stations, and also sets up a pick-up hole to facilitate picking up the workpiece. The processing stations set up by the former are all compatible with the mobile phone cover, but a factory often manufactures different types of covers, and there will be different sizes of covers that need to be processed. This device only provides one type of cover. It is convenient. When processing other types of cover plates, people often need to make new devices, which will increase the waste of resources, and the device may be disassembled and replaced many times. Unnecessary damage may occur. The device will still be a lot of inconvenience
