Foam attaching device for mobile phone touch screen

Abstract

The invention relates to the technical field of mobile phone touch screen accessory devices, in particular to a foam attaching device for a mobile phone touch screen. Automatic attaching can be achieved, the attaching position is precise, the finished product rate is increased, continuous operation is achieved, the automation degree is improved, manpower is reduced, the economic cost is reduced, the using limitation is reduced, and the using reliability is improved. The foam attaching device comprises a workbench, four groups of supporting legs, a left supporting plate, a right supporting plate and a top plate; the foam attaching device further comprises a back side plate, a first hydraulic cylinder, a second hydraulic cylinder, a hydraulic station, a control box, a left connecting plate,a right connecting plate, an upper pressing plate, a lower pressing plate, a supporting plate, four groups of foam attaching heads and an attaching plate; the top end of the back side plate is connected with the back side of the bottom end of the top plate, and the bottom end of the back side plate is connected with the back side of the top end of the workbench; and the supporting plates are located in front of the back side plate, two groups of first sliding blocks are longitudinally arranged at the back ends of the supporting plates, two groups of first sliding grooves are longitudinally formed in the front end of the back side plate correspondingly, and the two groups of first sliding blocks are in sliding fit with the two groups of first sliding grooves.

Description

technical field [0001] The invention relates to the technical field of mobile phone touch screen accessories, in particular to a foam bonding device used for the mobile phone touch screen. Background technique [0002] As we all know, during the production process of mobile phone touch screens, it is necessary to paste foam on 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, it can only be pasted on the edge. The foam laminating device for mobile phone touch screen is an accessory device used for foam lamination on the back of mobile phone touch screen in order to better isolate the liquid crystal module and touch screen. It has been obtained in the field of automation Widely used; the existing foam lamination device for mobile phone touch screen comprises workbench, four groups of legs, left support plate, right support plate, top plate and foam lamination device, ...

[0002] As we all know, during the production process of mobile phone touch screens, it is necessary to paste foam on 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, it can only be pasted on the edge. The foam laminating device for mobile phone touch screen is an accessory device used for foam lamination on the back of mobile phone touch screen in order to better isolate the liquid crystal module and touch screen. It has been obtained in the field of automation Widely used; the existing foam lamination device for mobile phone touch screen comprises workbench, four groups of legs, left support plate, right support plate, top plate and foam lamination device, and the tops of four groups of legs are respectively connected with The left front side, the left rear side, the right front side and the right rear side of the bottom end of the workbench are connected, the bottom end of the left support plate is connected with the left side of the workbench top, the bottom end of the right support plate is connected with the right side of the workbench top, and The tops of the left support plate and the right support plate are respectively connected with the left side and the right side of the bottom of the top plate, and the foam fitting device is arranged on the top of the workbench; Turn the mobile phone touch screen over and place it on the top of the workbench, so that the back of the mobile phone touch screen faces up, and then use the foam bonding device to align the edge of the mobile phone touch screen and perform foam bonding; the existing foam paste for mobile phone touch screen During the use of the joint device, it was found that manual foam lamination, the lamination position is inaccurate, not only the yield rate is low, it does not meet the continuous production process of the factory, it cannot meet the supply demand of the market, wastes a lot of manpower, and increases the economic cost at the same time, and the use is limited Higher reliability, resulting in lower available reliability
