[0028] The working principle of the present utility model is as follows: when in use, the forward and reverse motors 2, the material pumping pump 22 and the electric push rod 20 are powered on, and the display screen that needs to be glued is placed on the telescopic box 16. Since the strong spring 24 has a certain elasticity and telescopic force, it can pull the clamping plate 15 outward, so that display screens of different widths can be placed. After the display screen is placed, the strong spring 24 can be contracted to facilitate fixing the display screen on the telescopic box 16. The material pumping pump 22 can extract the glue inside the storage box 7 outward, and discharge it downward through the connecting pipe 10, the telescopic hose 11 and the glue discharge head 13, so that the fixed display screen can be glued. During the gluing process, the power provided by the electric push rod 20 can drive the slider 17 to slide inside the slideway 19. When the slider 17 slides, it can drive the telescopic box 16 and the display screen fixed above it to move, so that different positions of the display screen can be glued.

[0029] When the gluing process needs to be adjusted according to the different widths of the display screen, the power provided by the forward and reverse motors 2 can drive the forward and reverse threaded screws 6 to rotate. When the forward and reverse threaded screws 6 rotate, the slide plates 8 connected by threads and the slide plates 8 are slidably connected to the inside of the slide 3, which can directly drive the slide plates 8 to adjust laterally. When the slide plates 8 are adjusted laterally, since the telescopic hose 11 can be retracted, the glue heads 13 can be directly driven to move away from or closer to each other. When the glue heads 13 are adjusted, it is convenient to apply glue to display screens of different widths, thereby improving work efficiency.
