Problems solved by technology

There are following defects in the prior art: 1. Adhesive is laid on three sides of the bonding surface of the screen module against the cover plate, and manual bonding will cause the surface of the module to be uneven and easily generate air bubbles
2. The FPC cable (34) and PCBA board (35) extending from the display screen are bent on the back of the backlight. When the screen module and the cover are pressed together, the backlight is easily crushed by the PCBA, or the appearance is abnormal
3. FPC and PCBA are covered with copper foil as a whole. When the screen mold is pressed with the cover plate, the copper foil is easy to wrinkle

Abstract

The invention discloses a high-yield display screen module pressing machine, which includes a pressure bearing table, a pressure applying machine and a vacuuming device, the pressure bearing table is used to place the screen module and a cover plate, and the pressure applying machine includes The pressure head (1), the vacuum cover (2) and the pressure applying mechanism, the vacuum pumping device is connected to the vacuum cover, and the vacuum cover adopts a lid-shaped structure with an opening at the bottom, the pressure head is located in the center of the vacuum cover, and the vacuum cover is in the center of the vacuum cover. Driven by the pressing mechanism, it can be buckled on the pressure-bearing platform, and the screen module and the cover plate can be buckled in the vacuum cover. The vacuum device can vacuum the cavity in the vacuum cover. The pressure head Driven by the pressing mechanism to move down, the cover plate and the screen module are pressed together; the invention has high degree of automation and high production efficiency, and the produced display module has no bubbles, no crushing, no wrinkles, and a high yield rate.

Description

technical field [0001] The invention relates to display screen processing equipment, in particular to a high-yield display screen module pressing machine. Background technique [0002] During the processing of the display screen of a mobile phone or a tablet computer, it is necessary to bond the screen module and the cover plate (31) together to form a display assembly. see Figure 6 , the screen module includes a display screen (32) and a backlight source (33). There are the following defects in the prior art: 1. Glue is laid on three sides of the bonding surface of the screen module against the cover plate, and manual bonding will cause the surface of the module to be uneven and easily generate air bubbles. 2. The FPC cable (34) and PCBA board (35) extending from the display screen are bent on the back of the backlight. When the screen module and the cover are pressed together, the backlight is easily crushed by the PCBA, or the appearance is abnormal. 3. FPC and PCBA ar...
