Description

Auxiliary equipment for pasting double-sided adhesive lines on LED backlight panels

technical field

The utility model relates to the field of auxiliary equipment for processing LED backlight panels, in particular to an auxiliary equipment for pasting double-sided glue lines on LED backlight panels.

Background technique

The double-sided glue line of the LED backlight board is mainly used to connect the liquid crystal on the backlight board and the backlight source, and play the role of fixing and shading. According to the size of the liquid crystal in production, it can be designed into different widths and viscosities. Generally, four double-sided adhesive lines are required, and the four sides form a rectangular ring to ensure the stability of the entire module. There are strict requirements on the position of the double-sided adhesive lines during production, and the general error is within 0.2mm, which is both beautiful requirements, as well as the requirement to ensure the position of the liquid crystal and the backlight source, so as to ensure the light entering the back of the liquid crystal. At present, the double-sided adhesive line is cut into rolls of precise width, and most of the adhesive lines are glued by hand. The production efficiency of manual pasting is generally: 1,000 pieces per person per day, usually based on the specific position on the backlight board as a reference , so the pass rate is not easy to guarantee, and one-time production is often very large, so the detection is difficult, and the workload is huge, so if the accuracy of the glue line can be improved in production, the pass rate can be greatly improved and the detection intensity can be reduced.

When the glue line positioning groove is too deep, it is easy to deform, so the glue line The depth of the positioning groove should be between 0.2-0.4cm.

The utility model is an auxiliary device for pasting double-sided adhesive lines on LED backlight boards. The user snaps the LED backlight board to be pasted with double-sided adhesive into the backlight board slot of the auxiliary device, and puts the required auxiliary device for pasting glue together. Pull the glue wire reel on the glue wire positioning bracket on the side, press the glue wire on the LED backlight board along the glue wire positioning groove, and press lightly with your hands so that the glue wire sticks to the LED backlight board, and wait for the glue wire to be attached After that, slide the movable cutter to cut off the two ends of the glue line, and then remove the LED backlight panel. The whole operation is extremely simple, and the glue line positioning groove is used to position the glue line accordingly during the operation, so the glue line is positioned Accurate, high pass rate.
