Attaching transport mechanism of touch screen ultraviolet (UV) laminating machine

Abstract

An attaching transport mechanism of a touch screen ultraviolet (UV) laminating machine comprises a rack, a cantilever type sucker turnover mechanism, a four-axis fine turning attaching mechanism and a double-position feeding mechanism. The cantilever type sucker turnover mechanism is arranged above the rack, the four-axis fine turning attaching mechanism is arranged below the rack, the double-position feeding mechanism is arranged on the side of the four-axis fine turning attaching mechanism, the cantilever type sucker turnover mechanism is arranged on the rear side of the four-axis fine turning attaching mechanism. The four-axis fine turning attaching mechanism is composed of a workpiece vacuum sucker which is arranged on the top, a servo motor, a linear guide rail and an attaching cylinder. The attaching cylinder and the cantilever type sucker turnover mechanism are connected, and a controller presses downwards along the linear guide rail to ensure attaching parallel accuracy. The servo motor is connected with the workpiece sucker by the rotary shaft and controls turnover to ensure accuracy of an angle of a turnover mechanism. A product after attached does not spill over glue, attaching accuracy and thickness can be ensured, high-accuracy and automatic control operation procedures are achieved, and transport attaching motion is effectively completed.

Description

technical field [0001] The invention belongs to the field of touch screen UV glue laminating machine manufacturing, and relates to a touch screen UV glue laminating machine integrating glue supply, glue dispensing, laminating and pre-curing, in particular to a touch screen UV laminating machine laminating and conveying mechanism; This touch screen UV glue laminating machine is mainly used for capacitive touch screen liquid glue lamination. Background technique [0002] In the production process of capacitive touch screens, most of the two glass substrates of cover glass and sensor glass need to be precisely bonded together. The middle adhesive layer has solid optical glue or liquid optical glue (hereinafter referred to as liquid glue or water glue). Liquid glue lamination can reduce material costs. The lamination process requires no lack of glue, no air bubbles, no deviation between upper and lower glass panels, and uniform lamination thickness. [0003] At present, in the ...

Chinese patent document CN201020673902.9 discloses a vertical touch screen dispensing and turning laminating machine, which includes a three-axis motion dispensing system, a main frame, a blower, a touch screen controller, a dispensing controller, left and right vacuum adsorption turning and laminating machines The left and right vacuum adsorption flipping and laminating mechanisms are controlled by air cylinders, and the controllability of the flipping angle is poor. After the lamination is completed, it is pushed out by the ejecting mechanism, and the glass panel will be removed by the next curing system. Adhesive pre-curing

[0004] Although the above equipment has been used for many years, there are still some deficiencies. The main reason is that when the motion dispensing system is operated, it is easy to overflow the glue and cannot accurately guarantee the lamination accuracy.
