Make like this the position of screen module 100 can be spacing fast, only need place behind the screen module 100 support by just having looked for after the spacing portion the position. Thereby improving the placement efficiency. The production efficiency is improved. In addition, a placement groove 620 is formed on the upper surface of the positioning housing 610. Therefore, the placing groove 620 is overhead for the screen module 100 placed on the positioning shell 610, so that the screen module 100 can be conveniently taken and placed.

The specific working principle and process are as follows: first, the positioning plate 310 on which the display screen module to be filmed is placed is pulled into between the glue pressing mechanisms 400 on both sides by the pulling cylinder. Then, the positioning plate 310 is jacked up by the jacking cylinder, and the attached black adhesive 110 film is extruded to the side edges (left and right side surfaces) of the display screen module through the lower adhesive rollers 420 on the two sides in the ascending process of the module. Then, the upper rubber roller 410 and the lower rubber roller 420 on the two sides are controlled to move towards the center, and at the moment, the distance between the upper rubber roller 410 and the lower rubber roller 420 on each side is adjusted and kept to be just suitable for or slightly closely matched with the thickness of the screen module 100, so that in the two rubber rollers on the same side, the upper rubber roller 410 can press the edge of the original attached upper black rubber 110 film, and the lower rubber roller 420 is used for extruding and attaching the edge of the lower side. The rubber rollers on the two sides work simultaneously. And the upper glue roller 410 and the lower glue roller 420 on each side simultaneously press the black glue 110 from the upper and lower sides, thereby ensuring the upper and lower balance of force and maintaining the side edges of the flat bonding module.

It is easy to think that, because the first attached black adhesive 110 film is manually completed and the display screen module to be further attached with the black adhesive 110 film is manually placed on the product positioning block 600, the above-mentioned manual operation can be replaced by the arrangement of a more complicated automatic arm, thereby forming a more automated process.

In addition, the black glue 110 can be directly attached from the bottom side in a large area, and after positioning is performed by arranging a positioning hole, attachment processing is performed. Although the black adhesive 110 film may be wasted, the black adhesive 110 film may be simultaneously attached from three sides, for example, the third side adhesive pressing mechanism 400 or the fourth side adhesive pressing mechanism is added, and the center of the existing two-side adhesive roller set of the above-mentioned scheme is disposed near the front end, so that the black adhesive 110 is simultaneously attached to the three sides of the screen module 100.
