[0036] Baffles that interfere with the clamp 53 are fixedly connected to both ends of the upper surface of the connecting frame 4, and a circular chamfer is provided at the lower end of the clamp 53. The baffles are used to limit the clamp 53 in the compressed state of the spring 52, so as to facilitate the lifting and lowering of the upper pressing mold 6 under the connecting frame 4 through the locking assembly 5 when the lifting assembly 2 is lifted.

[0037] When in use, the display screen assembly and the frame are placed on the lower pressing mold 8, and the adjusting screw 91 is rotated according to the height of the frame, so that the adjusting screw 91 drives the side slider 92 to move in the side groove 82, so that the side sliding quick-acting support plate 94 is raised, and then the support height of the support plates 94 of the two sets of limit assemblies 9 is made to be the same through the scale groove 83, and the Y-axial position of the frame on the lower pressing mold 8 is corrected by the correction assembly 7, and the forward and reverse motor 22 drives the lifting screw 23 to drive the connecting frame 26 to descend, first descend to the top of the frame, and then through the upper pressing The correction component 7 on the closing mold 6 corrects the display screen assembly and the frame in the X-axis direction, and the forward and reverse motor 22 is started again, so that the upper pressing mold 6 presses the display screen assembly and the frame. The frame is pressed by the pressure strip, and the four ends of the upper surface of the support plate 94 support the upper pressing mold 6 to avoid damage to the display screen caused by excessive pressure of the upper pressing mold 6. At the same time, the display screen assembly and the frame are soft-pressed by the rubber pad 62, thereby improving the pressing effect of the display screen assembly and the frame, reducing the probability of damage to the display screen caused by frame pressing, and improving production efficiency.
