[0033] One side of the electric sliding groove 41 is slidably connected with a connecting frame 45, the connecting frame 45 cooperates with the connecting seat 47 to realize FPC soft plate turnover, during turnover, the connecting frame 45 limits the upward height of the connecting seat 47, when the connecting seat 47 moves downward, the connecting frame 45 can be pushed to slide on a guide sliding groove 46, so that the connecting frame 45 can still limit the upward height of the connecting seat 47 when the connecting seat 47 moves upward next time, and prepares for the next turnover action.

[0034] One side of the electric sliding groove 41 is fixedly connected with the guide sliding groove 46, the connecting frame 45 is slidably connected on the guide sliding groove 46, the slot of the guide sliding groove 46 is in inverted T-shaped structure, thereby ensuring that the connecting seat 47 will not drive the connecting frame 45 to move upward when the connecting seat 47 moves upward, and ensuring the stability of the limiting of the connecting frame 45.

[0035] The connecting frame 45 comprises a U-shaped plate 451, a guide plate 452 is fixedly connected in the middle of the U-shaped plate 451, two baffles 453 are fixedly connected above both sides of the U-shaped plate 451, the connecting seat 47 comprises a supporting plate 471, one side of the supporting plate 471 is fixedly connected with a round rod one 472, the other side of the supporting plate 471 is fixedly connected with a round rod two 473, the supporting plate 471 is combined by one round plate and two extension plates which are spaced and symmetrically arranged, and the two baffles 453 respectively cooperate with the round rod one 472 and the round rod two 473;

[0036] The guide plate 452 is in triangular plate structure, when the fixing rod 48 moves downward after completing turnover, the supporting plate 471 is in vertical state (such as Figure 3 and Figure 4 the state of the supporting plate 471 in the middle), and the round rod one 472 and the round rod two 473 move downward together, and the round rod one 472 and the round rod two 473 are located on the same vertical line, when the round rod one 472 and the round rod two 473 move downward to below the connecting frame 45, the round rod one 472 and the round rod two 473 can push and extrude the guide plate 452 along one side of the guide plate 452, so that the connecting frame 45 is offset to one side as a whole, and then the baffle 453 on one side can move to above the round rod one 472 and the round rod two 473, thereby limiting the height of the round rod one 472 and the round rod two 473, and facilitating the turnover of the connecting seat 47 next time, when the round rod one 472 and the round rod two 473 push and extrude another inclined surface of the guide plate 452 next time, the connecting frame 45 is reset.

[0038] Embodiment Two

[0039] Based on Embodiment One, refer to the accompanying drawings Figures 4-6 The clamping assembly 3 includes a U-shaped groove 31, and two flexible pads 34 are arranged on the upper sides of the U-shaped groove 31. The two flexible pads 34 can ensure the stability of positioning the FPC board and avoid uneven clamping surfaces of the flexible pads 34 due to improper adjustment. The middle part of one side of the flexible pad 34 extends out of the U-shaped groove 31 and is fixedly connected with a threaded rod 32. An adjusting handle 33 is rotatably connected to the outer side of the threaded rod 32 on the U-shaped groove 31. An inner thread is formed in the middle part of the adjusting handle 33. The adjusting handle 33 is threadedly connected with the threaded rod 32. When the adjusting handle 33 is rotated, the threaded rod 32 can be moved, thereby moving the flexible pad 34 to clamp and fix the FPC board or separate from the FPC board.

[0040] A soft pad 35 is fixedly connected in the U-shaped groove 31. The soft pad 35 is L-shaped. The threaded rod 32 is slidably connected to the inner side of the soft pad 35.

A fixed plate 49 is fixedly connected to the lower side of one side of the supporting shell 42. A tension spring 44 is connected between the connecting plate 43 and the fixed plate 49. The connecting plate 43 and the fixed plate 49 are outwardly convex on one side, so that the fixed rod 48 has a certain distance from the tension spring 44, preventing the fixed rod 48 from affecting the extension of the tension spring 44 and being able to position the end of the tension spring 44 to ensure the stability of the connection of the tension spring 44. Before turnover, the tension spring 44 can pull the connecting plate 43 to avoid self-rotation of the connecting plate 43. After turnover, the tension spring 44 can quickly reset the connecting plate 43.

The electric sliding groove 41 is fixedly connected to the bottom plate 1. Before and after turnover, the clamping assembly 3 can be placed in the opening 21 above. When the clamping assembly 3 is placed on the operation table 2, the soft pad 35 is at the same horizontal height as the upper surface of the operation table 2, which is convenient for positioning and clamping the FPC board. When the processing range on the FPC board is small, even if one end of the FPC board is connected in the clamping assembly 3, it will not affect the processing operation, and the operation table 2 can always support the FPC board.
