When the back glue on the right side is defoaming, the workpiece without glue is placed in the fixed plate on the left side for gluing. After waiting for the gluing to be completed, the two motors are controlled to drive the two screw rods to rotate respectively. The screw rod on the left side drives the workpiece on the left side to move backward through the moving block on the left side to perform the defoaming operation. The screw rod on the right side drives the workpiece on the right side to move forward through the moving block on the right side.

[0026] When bubbles exist between the backing glue and the workpiece, they need to be processed. In order to reduce the labor of workers, ensure the production cost and production cycle, and improve production efficiency, the defoaming component 7 is used to automatically eliminate the bubbles. The specific structure is: the defoaming component 7 includes an electric cylinder 71, and the electric cylinder 71 is installed in the middle of the upper end of the U-shaped frame 6. The output end of the electric cylinder 71 moves through the upper wall of the U-shaped frame 6 and is fixedly connected to a connecting plate 72. A plurality of springs 73 distributed in a linear needle array are installed at the lower end of the connecting plate 72. A U-shaped plate 74 is installed together at the lower ends of the plurality of springs 73. The interior of the U-shaped plate 74 is rotatably connected to a rubber roller 75 through a rotating shaft. The spring 73 is used to buffer the position of the rubber roller 75 to prevent the rubber roller 75 from flattening the backing glue.

[0027] Since defoaming requires a certain amount of time, the defoaming time can be utilized by cooperating with the driving component 8 and the two fixed plates 4 to improve work efficiency. The specific structure is as follows: the driving component 8 includes a motor 81 and a screw rod 82. Two motors 81 are provided.

[0031] The utility model provides a back-adhesive bubble-free laminating fixture. When the right workpiece is glued, the right motor 81 is controlled to drive the right screw 82 to rotate. The right screw 82 drives the right fixed plate 4 and the workpiece to move backward through the right moving block 83 to perform a defoaming operation. When the right workpiece moves below the rubber roller 75, the output end of the electric cylinder 71 is controlled to drive the connecting plate 72 to move downward. The connecting plate 72 drives the U-shaped plate 74 and the rubber roller 75 to move downward through the spring 73, so that the rubber roller 75 contacts the back adhesive. When the back adhesive moves backward, When moving, the rubber roller 75 presses out the bubbles between the back glue and the product. When defoaming, the workpiece without glue is placed in the fixed plate 4 on the left for gluing. After waiting for the gluing to be completed, the two motors 81 are controlled to drive the two screw rods 82 to rotate respectively. The screw rod 82 on the left drives the workpiece on the left to move backward through the moving block 83 on the left to perform the defoaming operation. The screw rod 82 on the right drives the workpiece on the right to move forward through the moving block 83 on the right. At this time, the workpiece that has been defoamed is removed and a new workpiece is placed for gluing, and the workpiece can be continuously glued.
