[0002] A circuit board vertical positioning frame can position the circuit board on a vertical frame, allowing the circuit board to be moved in the chemical treatment tank along with the positioning frame for chemical treatment. However, flexible circuit boards are best stretched flat before chemical treatment to obtain a uniform chemical treatment effect. However, only a few known circuit board vertical positioning frames have the function of stretching flexible circuit boards flat, and the flexible circuit boards can only be stretched manually. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the prior art can only manually stretch and support flexible circuit boards, and to achieve the function of automatically stretching and supporting flexible circuit boards.

[0004] To achieve the above objectives, the technical features of this utility model include: a top platform; a vertical frame, the top of which is connected to the bottom of the top platform; a fixed clamping plate module, in which a fixed rod is disposed on the vertical frame, the fixed rod being provided with a plurality of fixed-side clamps; a movable clamping plate module, in which a movable rod is disposed on the vertical frame, the movable rod being provided with a plurality of movable-side clamps, the fixed-side clamps and the movable-side clamps having clamping directions facing each other, and the circuit board being clamped and positioned by each of the fixed-side clamps and each of the movable-side clamps; at least one tensioner, disposed between the movable rod and the vertical frame, causing the movable rod to move away from the fixed rod and generate tension on the clamped and positioned circuit board; and at least one movable rod linkage frame, one end of which is locked to the movable rod, and the other end protruding outside the vertical frame.

[0005] Furthermore, the vertical frame has a pair of straight frame bars and a bottom frame bar. The fixed rod is horizontally arranged on the pair of straight frame bars, and the movable rod is horizontally arranged on the pair of straight frame bars, with the movable rod located below the fixed rod. Each pair of straight frame bars is provided with a movable guide post, a guide post slider, an upper limit block, and a lower limit block. The upper limit block, the guide post slider, and the lower limit block are arranged sequentially from top to bottom on the movable guide post. The pair of guide post sliders are connected to both ends of the movable rod. Each pair of straight frame bars has a guide post notch, allowing the movable guide post, the guide post slider, the upper limit block, and the lower limit block to be recessed into the guide post notch. The movable rod linkage frame has a pair of lower hook plates, a bridging plate, and a pair of locking fasteners. The bottom end of the pair of lower hook plates has a lower hook piece, and the top end of the pair of lower hook plates is arranged on the movable rod, with the lower hook piece located below the bottom frame bar.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0037] The following is a reference to the appendix. Figure 1 To be continued Figure 3 The present invention comprises: a top platform 10; a vertical frame 20, the top end of which is connected to the bottom of the top platform 10, the vertical frame 20 having a pair of straight frame bars 21 and a bottom frame bar 22; a fixed clamping plate module 30, with a fixed rod 31 laterally disposed on the pair of straight frame bars 21, the fixed rod 31 having a number of fixed side grippers 32; a movable clamping plate module 40, with a movable rod 41 laterally disposed on the pair of straight frame bars 21, the movable rod 41 being located below the fixed rod 31, the movable rod 41 having a number of movable side grippers 42, the fixed side grippers 32 and the movable side grippers 42 having clamping directions facing each other; at least one tensioner 50 disposed between the movable rod 41 and the bottom frame bar 22; and at least one movable rod linkage frame 60, one end of which is locked to the movable rod 41, and the other end protruding outside the vertical frame 20.

[0038] Next, please refer to Figure 4A , Figure 4BAs shown, each of the straight frame bars 21 has a guide post notch 23. Each guide post notch 23 is provided with a movable guide post 24, a guide post slider 25, an upper limit block 26, and a lower limit block 27. The upper limit block 26, the guide post slider 25, and the lower limit block 27 are arranged one by one from top to bottom on the movable guide post 24. The pair of guide post sliders 25 are connected to both ends of the movable rod 41. The tensioner 50 is a pair of tension springs arranged between the movable rod 41 and the bottom frame bar 22. The movable rod linkage frame 60 has a pair of lower hook plates 61, a bridging plate 62, and a pair of locking fasteners 63. The bottom end of the pair of lower hook plates 61 has a lower hook piece 611. The top end of the pair of lower hook plates 61 is arranged on the movable rod 41, so that the pair of lower hook pieces 611 are located below the bottom frame bar 22. The bridging plate 62 spans the pair of lower hook pieces 611 and is locked by the pair of locking fasteners 63.

[0039] Based on this structure, please refer to Figure 5 As shown, this utility model uses the fixed-side grippers 32 of the fixed rod 31 and the movable-side grippers 42 of the movable rod 41 to clamp and position the flexible circuit board 70. The tensioner 50 is used to move the movable rod 41 away from the fixed rod 31. The tension provided by the tensioner 50 can automatically stretch the flexible circuit board 70. Before clamping the flexible circuit board 70, an external pneumatic cylinder (not shown) is used to push the movable rod linkage 60 upward. After the flexible circuit board 70 is clamped and positioned, the external pneumatic cylinder is released, and the tensioner 50 automatically stretches the flexible circuit board. Therefore, this utility model has the function of automatically stretching the flexible circuit board.
