Attaching mechanism of foam attaching device used for touch screen

Abstract

The invention discloses an attaching mechanism of a foam attaching device used for a touch screen. The attaching mechanism comprises an attaching fixed plate, a feeding swing arm, a feeding driving device, a pressing assembly, a cutting-off assembly, a first sliding block and a second sliding block, wherein the first sliding block and the second sliding block cooperate with each other. The feedingdriving device is installed on the attaching fixed plate, an output shaft of the feeding driving device is hinged to the middle or the rear end of the feeding swing arm through the first sliding block, and the first sliding block is obliquely and slidably installed on the attaching fixed plate through a first sliding rail assembly. The second sliding block is obliquely and slidably installed on the attaching fixed plate through a second sliding rail assembly, and the second sliding block is hinged to the front end of the feeding swing arm in a cooperation manner. The feeding swing arm is provided with a feeding groove which extends in the front-back direction and is used for allowing foam strips to penetrate. The pressing assembly is installed on the attaching fixed plate and located in front of the feeding swing arm. The cutting-off assembly is installed on the attaching fixed plate and used for cutting off the foam strips. The attaching mechanism has the advantages of being high inprocessing efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of bonding devices, in particular to a bonding mechanism of a foam bonding device for a touch screen. Background technique [0002] As we all know, during the production process of mobile phone touch screens (or car touch screens, etc.), it is necessary to attach foam to the back of the product to prevent dust and interference between the LCD module and the touch screen. Since the foam is soft and cannot enter the visible area, Fitting is only possible at the edges. Traditionally, four strips of foam are attached to the workpiece manually, and then the excess part after the attachment is cut off. However, manual foam bonding, the bonding position is not accurate, not only the yield is low, it does not meet the continuous production process of the factory, the efficiency is slow, it cannot meet the supply demand of the market, a lot of manpower is wasted, and the economic cost is increased at the same time, ...

However, manual foam bonding, the bonding position is not accurate, not only the yield is low, it does not meet the continuous production process of the factory, the efficiency is slow, it cannot meet the supply demand of the market, a lot of manpower is wasted, and the economic cost is increased at the same time, and the use is limited. Higher, resulting in lower available reliability
