Background technique

The existing methods of laminating and assembling frames and adhesive backings generally include the following two methods: First, two sets of adhesive backing assembly and lamination jigs are used. The first work station requires two workers. First, the upper part of the frame is / Place the adhesive on the lower side inside the jig slot (the adhesive release film faces downward to prevent the adhesive from sticking into the jig slot), then place the frame male mold face down in the jig slot, and finally pass the equipment The upper mold presses the backing glue, activates the adhesiveness of the upper/lower side backing, and makes the backing glue adhere to the male mold surface of the frame. After the pressing is completed, take out the frame with the upper/lower side backing glue attached and transfer it to the next step through the assembly line. Work station; the second work station requires two workers to first place the left/right side glue of the frame in the jig slot, then place the male mold of the frame face down in the jig slot, and finally press the mold together on the equipment Adhesive, activate the adhesiveness of the left/right side adhesive, so that the adhesive adheres to the male mold surface of the frame, and completes the assembly of the four adhesive strips of the frame; in this solution, the product requires two clampings, two pressings, and four manpower After assembly is completed, the appearance of the product may be easily scratched during the clamping process.

Second, use two sets of adhesive-backed assembly jigs and one set of adhesive-backed pressing jigs: Position the frame shape and the adhesive-backed release film positioning holes. At the first station, place the frame male mold face up on the back. In the slot of the glue assembly jig, two manpower is needed to assemble the upper/lower side glue of the frame to the male mold surface of the frame through the positioning holes on the adhesive release film (the adhesive release film faces upward), and at the same time gently use your fingers. Press the adhesive to prevent the adhesive from falling off, take out the frame with the upper/lower adhesive attached, and transfer it to the next work station through the assembly line; at the second station, place the male mold of the frame face up in the adhesive-backed assembly jig slot Inside, two manpower is needed to assemble the left/right side adhesive of the frame onto the male mold surface of the frame through the positioning holes on the adhesive release film. At the same time, lightly press the adhesive with your fingers to prevent the adhesive from falling off. Take out and stick the left/right sides The glue-backed frame on the right side is transferred to the next work station through the assembly line; the third work station requires a manpower to place the frame in the glue-backed lamination jig, and operate the machine to press the glue on the equipment and activate the four Adhesive backing. Therefore, this method requires more labor.
