[0046] The present invention also provides a method for using a flexible flat cable production detection device, comprising the following specific steps:

[0047] Step 1: First, by rotating the extrusion block upward around the fixed axis, the extrusion block squeezes and deforms the torsion spring, and the soft flat cable to be tested is placed in the inner cavity of the placement groove. The elastic effect of the torsion spring is used to drive the extrusion block to rotate, so that the bottom end of the extrusion block presses the upper surface of the soft flat cable downward, and then the adjusting screw is rotated to drive multiple fixed blocks to move, and multiple limit blocks move to one side to squeeze and push one side of the soft flat cable, so that the other side of the soft flat cable fits with the inner wall of the placement groove, and the soft flat cable is limited and fixed;

[0050] Technical effects and advantages of the present invention:

[0051] (1) The present invention utilizes a mounting frame, a stopper block, an extrusion block, a mounting column, a movable rod, a clamping block and a clamping groove in a coordinated arrangement. By moving one of the stopper blocks along the mounting frame, the extrusion block is driven to move toward one end of the flexible flat cable. The stopper block pushes the mounting column and the movable rod to move together. The clamping block slides in the inner cavity of the clamping groove along with the mounting column, so that one of the stopper blocks, the extrusion block and the movable rod move to one end of the flexible flat cable, thereby facilitating the fixing and testing of flexible flat cables of different lengths.

[0052] (2) The present invention utilizes a configuration method in which an extrusion block, a limit block, a torsion spring, an adjusting screw, a fixed block and a placement groove are matched. By rotating the extrusion block upward around a fixed axis, the extrusion block squeezes and deforms the torsion spring, and the flexible flat cable to be tested is placed in the inner cavity of the placement groove. The elastic effect of the torsion spring is utilized to drive the extrusion block to rotate, so that the bottom end of the extrusion block presses downward on the upper surface of the flexible flat cable. The adjusting screw is then rotated to drive multiple fixed blocks to move, and multiple limit blocks move to one side to squeeze and push one side of the flexible flat cable, so that the other side of the flexible flat cable fits with the inner wall of the placement groove, which facilitates the limited fixing of the flexible flat cable.

[0053] (3) The present invention utilizes a mounting seat, a movable block, a detection needle, a compression spring and a movable rod in a coordinated arrangement. By rotating the movable rod around a connecting shaft, a plurality of mounting seats and movable blocks are driven to move to the upper position at both ends of the flexible flat cable. Then, the bolt is rotated and tightened. One end of the bolt is pressed and fixed against the outer wall of the fixing seat to ensure the stability of the mounting column and the movable rod. The elastic effect of the compression spring is utilized to push the movable block and the detection needle downward so that the bottom end of the detection needle fits with the metal ends at both ends of the flexible flat cable, thereby facilitating the testing of the flexible flat cable.

8. The flexible flat cable production detection device according to claim 7, characterized in that: The detection mechanism (5) further comprises: A compression spring (54), wherein the compression spring (54) is disposed in the inner cavity of the mounting seat (51), and the bottom end of the compression spring (54) is in contact with the upper surface of the movable block (52); Sliding grooves (55), the sliding grooves (55) are arranged on both sides of the bottom of the mounting seat (51); A sliding block (56), one end of which is fixedly connected to one side of the top of the movable block (52), and one end of which is slidably and interlacedly connected to the inner cavity of the sliding groove (55).

9. The flexible flat cable production detection device according to claim 8, characterized in that: The bottom end of the detection needle (53) fits against the bottom of the inner wall of the placement groove (32), one end of the torsion spring (36) is fixedly connected to the outer wall of the fixed shaft (35), and the other end of the torsion spring (36) is pressed against the inner wall of the accommodating groove.

10. A method for using a flexible flat cable production detection device, characterized in that: The specific usage steps are as follows: Step 1: First, the extrusion block (34) is rotated upward around the fixed axis (35), and the extrusion block (34) squeezes and deforms the torsion spring (36), and the flexible flat cable to be tested is placed in the inner cavity of the placement groove (32). The elastic effect of the torsion spring (36) is used to drive the extrusion block (34) to rotate, so that the bottom end of the extrusion block (34) presses the upper surface of the flexible flat cable downward, and then the adjusting screw (44) is rotated to drive the multiple fixed blocks (43) to move, and the multiple limit blocks (33) move to one side to squeeze and push one side of the flexible flat cable, so that the other side of the flexible flat cable fits with the inner wall of the placement groove (32), and the flexible flat cable is limited and fixed; Step 2: Then, by moving one of the limit blocks (33) along the mounting frame (42), the extrusion block (34) is driven to move toward one end of the flexible flat cable, the limit block (33) pushes the mounting column (45) and the movable rod (46) to move together, and the clamping block (48) slides in the inner cavity of the clamping groove (49) along with the mounting column (45), so that one of the limit blocks (33), the extrusion block (34) and the movable rod (46) move to one end of the flexible flat cable, thereby fixing flexible flat cables of different lengths; Step 3: Then, by rotating the movable rod (46) around the connecting shaft (47), the plurality of mounting seats (51) and the movable block (52) are driven to move to the upper position of the two ends of the flexible flat cable, and then the bolt (412) is rotated and tightened. One end of the bolt (412) is pressed and fixed to the outer wall of the fixing seat (31) to ensure the stability of the mounting column (45) and the movable rod (46). The elastic effect of the compression spring (54) is used to push the movable block (52) and the detection needle (53) downward, so that the bottom end of the detection needle (53) fits with the metal ends at the two ends of the flexible flat cable, which is convenient for testing the flexible flat cable.
