[0025] The ejection assembly 9 includes a return spring 904, and the return spring 904 is arranged below the movable plate 8.

[0026] Among them; the pressing component 5 includes a threaded rod 501, a handle 502 and a mounting plate 503. The threaded rod 501 is threadedly connected to the top plate of the L-shaped frame 4. The upper end of the threaded rod 501 is connected to the handle 502, and the lower end of the threaded rod 501 is rotatably connected to the mounting plate 503. A limiting sliding plate 504 is arranged on one side of the mounting plate 503. A strip-shaped sliding groove 401 is opened on the inner side of the vertical plate of the L-shaped frame 4. The L-shaped frame 4 is slidably connected to the limiting sliding plate 504 through the strip-shaped sliding groove 401. By rotating the handle 502, the threaded rod 501 can be effectively driven to rotate synchronously and move up and down. Under the limiting action of the limiting sliding plate 504, the threaded rod 501 drives the mounting plate 503 and the heating plate 6 to move synchronously. During the downward movement of the mounting plate 503 and the heating plate 6, the reinforcing sheet and the flexible circuit board inside the placement groove 701 can be effectively squeezed. The operation is simple, time-saving and labor-saving.

[0027] Among them; a circular hole 702 is opened at the center of the bottom surface of the placement groove 701. The ejecting component 9 further includes a top plate 901, a bottom plate 902 and a limiting telescopic rod 903. The top plate 901 is fixedly arranged at the center of the lower surface of the movable plate 8. The bottom plate 902 is arranged on the upper surface of the boss 101. The limiting telescopic rod 903 is arranged at the center of the lower surface of the top plate 901. The bottom plate 902 is arranged at the lower end of the limiting telescopic rod 903. A return spring 904 is sleeved on the outer surface of the limiting telescopic rod 903 and is located between the top plate 901 and the bottom plate 902. After the pre-pressing and attaching is completed, when the threaded rod 501 is rotated to drive the mounting plate 503 and the heating plate 6 to move upward, the return spring 904 releases energy to push the movable plate 8 upward. Then, the movable plate 8 can effectively eject the reinforced flexible circuit board inside the placement groove 701, which is convenient for removing the reinforced flexible circuit board. The operation is simple, time-saving and labor-saving.

[0028] Among them; the buffer column 2 includes a bottom tube, a support rod and a spring. The lower end of the bottom tube is fixedly connected to the boss 101. The spring is arranged inside the bottom tube. The lower end of the support rod is inserted into the bottom tube and is connected to the spring. The upper end of the support rod is connected to the positioning table 7. By providing the buffer column 2, when the heating plate 6 descends and presses the positioning table 7, the positioning table 7 descends and presses the buffer column 2. Through the contraction of the buffer column 2, the acting force can be effectively buffered.

[0029] Among them; a support column 10 is arranged at one end of the fixed base 1 away from the bearing member 3. A positioning hole is opened at the center of the upper surface of the support column 10. A positioning pin 11 is arranged on the upper end of the support column 10 through the positioning hole. A through hole 402 that cooperates with the positioning pin 11 is opened at the end of the horizontal plate of the L-shaped frame 4. By providing the bearing member 3, the L-shaped frame 4 can be rotated and opened, which is convenient for placing the flexible circuit board. By providing the support column 10, the horizontal plate of the L-shaped frame 4 can be effectively supported. By providing the positioning pin 11 and the positioning hole, when the lower end of the positioning pin 11 passes through the through hole 402 and is stuck into the positioning hole, the stability of the L-shaped frame 4 can be effectively ensured, and the L-shaped frame 4 can be prevented from rotating.

[0030] Working principle: By providing a bearing member 3, the L-shaped frame 4 can be rotatably opened, facilitating the placement of the flexible circuit board and the reinforcement sheet. By providing a support column 10, the horizontal plate of the L-shaped frame 4 can be effectively supported. By providing a positioning pin 11 and a positioning hole, when the lower end of the positioning pin 11 passes through the through hole 402 and is inserted into the positioning hole, the stability of the L-shaped frame 4 can be effectively ensured, preventing the L-shaped frame 4 from rotating.

[0031] Furthermore, by rotating the handle 502, the threaded rod 501 can be effectively driven to rotate and move downward synchronously. Under the limiting action of the limiting sliding plate 504, the threaded rod 501 drives the mounting plate 503 and the heating plate 6 to move synchronously. During the downward movement of the mounting plate 503 and the heating plate 6, the reinforcement sheet and the flexible circuit board in the placement groove 701 can be effectively squeezed. The operation is simple, time-saving and labor-saving. When the heating plate 6 descends and squeezes the positioning table 7, the positioning table 7 descends and squeezes the buffer column 2 and the return spring 904. By the contraction of the buffer column 2 and the return spring 904, the acting force can be effectively buffered. After the pre-pressing and attaching are completed, when the threaded rod 501 is rotated to drive the mounting plate 503 and the heating plate 6 to move upward, the return spring 904 releases energy to push the movable plate 8 upward. Then, the movable plate 8 can effectively eject the reinforced flexible circuit board in the placement groove 701, facilitating the removal of the reinforced flexible circuit board. The operation is simple, time-saving and labor-saving.
