[0024] When in use, by setting a moving groove and a moving component on the workbench 1, the positions of the two groups of moving seats 7 can be easily adjusted to adapt to OLED screens of different sizes and shapes. The C-shaped moving seat 7 and the first electric push rod 701 can be used to achieve accurate positioning and clamping of the OLED screen. The fitting connection between the clamping plate 702 and the rubber pad 703 not only ensures the uniformity of the clamping, but also the softness of the rubber pad 703 can avoid damage to the screen. The setting of the sliding component makes the clamping plate 702 more stable during movement, avoiding adverse effects on the OLED screen due to shaking.

[0025] The moving assembly includes a driving motor 2, a bidirectional threaded rod 4 and a first moving block 5. The base of the driving motor 2 is fixedly mounted on the side wall of the workbench 1. The output shaft of the driving motor 2 is fixedly connected to one end of the bidirectional threaded rod 4. The other end of the bidirectional threaded rod 4 is fixedly mounted on an inner wall of one side of the first moving groove 3 through a bearing. A threaded hole 6 is provided inside the first moving block 5. The first moving block 5 is threadedly connected to the bidirectional threaded rod 4 through the threaded hole 6. One side of the bottom end of the moving seat 7 is fixedly connected to the top of the first moving block 5. Through the combined structure of the driving motor 2, the bidirectional threaded rod 4 and the first moving block 5 of the moving assembly, accurate and efficient control of the moving seat 7 and the components installed above it is achieved. The design of the bidirectional threaded rod 4 enables the two first moving blocks 5 to move simultaneously and in opposite directions, which not only improves the working efficiency of the device, but also ensures that the clamping force on both sides can be applied synchronously when bending the OLED screen, thereby avoiding damage or deformation of the screen caused by uneven force.

[0026] The sliding assembly includes a first protrusion 704 and a first groove 705. The top of the first protrusion 704 is fixedly connected to the bottom of the pressure plate. The first groove 705 is opened at the inner top of the movable seat 7. The bottom end of the first protrusion 704 is slidably installed inside the first groove 705. Due to the sliding cooperation between the first protrusion 704 and the first groove 705, the pressure plate 702 can be quickly and accurately moved to the desired position, ensuring the precise fixation of the OLED screen, which not only shortens the bending cycle, but also improves the bending quality of the product.

[0027] A second moving block 9 is fixedly installed on the other side of the bottom end of the moving seat 7. A second moving groove 8 is also provided on the surface of the workbench 1. The bottom end of the second moving block 9 is movably connected in the second moving groove 8.

[0028] The extrusion assembly includes a second electric push rod 11, an extrusion plate 12 and an extrusion head 13. The extrusion plate 12 is arranged in a T shape. The base of the second electric push rod 11 is fixedly connected to the side wall of the fixed seat 10. The piston rod end of the second electric push rod 11 is fixedly connected to one side of the extrusion plate 12. The other side of the extrusion plate 12 is limitedly connected to one side of the extrusion head 13 through a limiting assembly. Through the telescopic movement of the second electric push rod 11, a stable and controllable thrust is provided to the extrusion plate 12. The other side of the extrusion plate 12 is limitedly connected to the extrusion head 13 through the limiting assembly, ensuring that the extrusion head 13 can remain stable when applying extrusion force without shaking or deflection, thereby further improving the bending accuracy and stability.

[0029] The limiting assembly includes a limiting block 14 and a limiting groove 15. One end of the limiting block 14 is fixedly connected to one side of the extrusion head 13, and the limiting groove 15 is arranged on the other side of the extrusion plate 12. The other end of the limiting block 14 is clamped in the inside of the limiting groove 15. This clamping method not only makes the connection between the limiting block 14 and the extrusion plate 12 firm and reliable, but also can prevent the limiting block 14 from falling off or shifting to a certain extent, thereby ensuring the stability and continuity of the extrusion head 13 when applying the extrusion force, and avoiding the interruption or error of the bending process caused by the failure of the limiting assembly.

[0030] A second protrusion 16 is fixedly installed at the bottom end of the extrusion plate 12, and a second groove 17 is opened on the surface of the workbench 1. The bottom end of the second protrusion 16 is slidably installed inside the second groove 17. Due to the sliding cooperation between the second protrusion 16 and the second groove 17, the extrusion plate 12 can maintain a stable position and posture when applying extrusion force, avoiding the problem of uneven distribution of extrusion force or wrong application position due to shaking or deviation.
