9. A screen encapsulation device for LED display processing according to claim 8, characterized in that, A clamping block (6) is fixedly connected to one side of the outer wall of the movable frame (36), a clamping groove is opened on the inner wall of the base (31), the inner cavity of the clamping groove is slidably inserted with the clamping block (6), and a handle (7) is fixedly connected to the upper surface of the movable frame (36).
10. A method for using a screen encapsulation device for LED display processing, characterized in that, Using a screen encapsulation device for LED display processing as described in claim 9, the following specific use steps are included: Step 1: First, place the screen to be processed into the inner cavity of the placement groove (32), and then rotate the movable frame (36) clockwise. The inner wall of the mounting groove (37) on the movable frame (36) presses against the bottom of the connecting column (38), pushing the connecting column (38) and the connecting block (34) to move horizontally. Multiple connecting blocks (34) drive the positioning blocks (33) to converge. Multiple positioning blocks (33) respectively push the outer wall of the plane, causing the screen to move to the center position of the placement groove (32). And multiple positioning blocks (33) press and fix the screen, positioning and aligning the screen with the lamination device (2) for lamination and encapsulation of the screen. Step 2: Then, as the movable frame (36) rotates, it drives the gear teeth (51) to rotate clockwise together. The inclined surface of the gear teeth (51) presses against the inclined surface at one end of the limit block (52), causing the limit block (52) to slide outward, releasing the limit of the limit block (52) on the gear teeth (51) and the movable frame (36). And the limit block (52) squeezes and deforms the second compression spring (55). Using the elastic force of the second compression spring (55), the limit block (52) is pushed back to the initial position, so that one end of the limit block (52) is inserted between adjacent gear teeth (51). By pulling the limit block (52) outward through the connecting rod (54), the limit block (52) is separated from the gear teeth (51). At this time, the movable frame (36) is driven to rotate counterclockwise. Step 3: Next, as the movable frame (36) rotates counterclockwise, the inner wall of the mounting groove (37) presses the connecting column (38) to move outward, driving multiple connecting blocks (34) and positioning blocks (33) to move outward, releasing the clamping of the screen. The mounting block (411) and the extrusion block (412) rotate counterclockwise together with the movable frame (36). When the connecting column (38) rotates into the inner cavity of the arc groove (413), the extrusion block (412) rotates to the position of the movable rod (47) and presses down on the top of the movable rod (47). The movable rod (47) rotates around the fixed shaft (49), and the bottom of the movable rod (47) rotates upward, pushing the fixed block (45) and the fixed rod (42) upward, squeezing and deforming the first compression spring (43), so that the lifting block (41) moves upward out of the receiving groove, pushing the screen upward, separating the screen from the bottom of the inner wall of the placement groove (32), and taking out the screen.
