[0030] like Figure 1 and Figure 4 As shown, to enhance the convenience and stability of restricting FPC flexible circuit boards, when using a welding machine for FPC flexible circuit board soldering, first connect the connector 10 to an external power source, then connect the base 4 to an external pneumatic device. Next, place the FPC flexible circuit board inside the restricting groove 7. Then, move the pressure block 16 downwards inside the second slide groove 19 via the second slider 23, so that the pressure block 16 restricts the FPC flexible circuit board. When the pressure block 16 restricts the FPC flexible circuit board, the second slider 23 is attracted by the magnetic plate 20 inside the second slide groove 19, thereby restricting the pressure block 16. At the same time... The protective pad 17 at the lower end of the pressure block 16 protects the FPC flexible circuit board, preventing damage to the FPC flexible circuit board when the pressure block 16 restricts it. At this time, the switch button 1 is turned on, and then the laser welding head 8 is controlled by the control panel 2 to weld the FPC flexible circuit board. The connector 10 and the support moving plate 12 facilitate the left and right movement and the forward and backward movement of the laser welding head 8. The arrangement of the first slide 18, the second slide 19, the pressure block 16, the second slider 23 and the magnet plate 20 enhances the convenience and stability of restricting the FPC flexible circuit board, while the protective pad 17 can protect the FPC flexible circuit board.

Then, the placement plate 6 is inserted into the slot 14 inside the upper end of the processing plate 5 by the locking block 15. When the locking block 15 enters the slot 14, the extrusion balls 22 on the front and rear sides of the slot 14 will extrude the locking block 15, thereby making the placement plate 6 installed on the upper end of the processing plate 5. At this time, the FPC flexible circuit board can be inserted into the restriction groove 7 inside the upper end of the placement plate 6. Through the setting of the locking block 15, the slot 14 and the extrusion balls 22, not only is the installation stability of the placement plate 6 enhanced, but the convenience of replacing the placement plate 6 is also enhanced, thereby providing better restriction for FPC flexible circuit boards of different sizes.
