DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-6 A flexible circuit board testing device includes a frame 1, a fixed fixture 2 is fixed on the frame 1, a movable fixture 3 is provided above the fixed fixture 2, a fixed frame 4 is fixed on the frame 1, and a rotating seat 5 is fixed on the top surface of the movable fixture 3;

[0024] The fixed frame 4 is provided with a driving structure, which includes a mounting frame 61, a hydraulic cylinder 62, a fixing rod 63, a threaded groove 64, a screw rod 65, a threaded sleeve 66, a lifting seat 67 and a threaded column 68. The mounting frame 61 is rotatably mounted on the top of the fixed frame 4 through a rotating shaft. The side of the mounting frame 61 fits in with the side of the fixed frame 4. A damping disc 8 is fixed on the rotating shaft. A damping plate 9 is fixed on the fixed frame 4, and the damping disc 8 is in contact with the damping plate 9. The damping disc 8 and the damping plate 9 are both made of rubber material. The design of the damping disc 8 and the damping plate 9 can provide damping for the rotation of the rotating shaft to prevent the rotating shaft and the mounting frame 61 from rotating under non-human conditions, thereby ensuring the stability of the hydraulic cylinder 62 during operation. The hydraulic cylinder 62 is mounted on the mounting frame 61, and the fixing rod 63 is fixed on the hydraulic At the telescopic end of the pressure cylinder 62, a threaded groove 64 is provided at the bottom end of the fixed rod 63, the screw rod 65 is threadedly sleeved in the threaded groove 64, and the bottom end of the screw rod 65 extends to the outside of the threaded groove 64, the threaded sleeve 66 is fixed to the bottom end of the screw rod 65, the lifting seat 67 is slidably sleeved on the fixed frame 4, and the lifting seat 67 is rotatably connected with the rotating seat 5, the threaded column 68 is fixed to the top surface of the lifting seat 67, and the threaded sleeve 66 is arranged opposite to the threaded column 68. The staff starts the hydraulic cylinder 62, so that the hydraulic cylinder 62 drives the lifting seat 67 to move upward through the fixed rod 63, the screw rod 64, the threaded sleeve 66 and the threaded column 68. When the lifting seat 67 moves upward, it can drive the movable clamp 3 to move upward through the rotating seat 5. When the movable clamp 3 moves upward, it can cooperate with the fixed clamp 2 to perform a tensile test on the flexible circuit board;

[0025] The frame 1 is also provided with a rotating structure, which includes two outer cylinders 71, two sliding plugs 72, two springs 73, two inner rods 74, a connecting pipe 75, a gear 76 and a rack 77. One of the outer cylinders 71 is fixed to the inner top surface of the frame 1, and the other outer cylinder 71 passes through the frame. The two sliding plugs 72 are respectively sealed and slidably connected in the two outer cylinders 71. The two springs 73 are respectively arranged between the two outer cylinders 71 and the two sliding plugs 72. One end of the two inner rods 74 is respectively fixed on the two sliding plugs 72, and the other end extends to the outside of the corresponding outer cylinder 71. One of the inner rods 74 is arranged opposite to the hydraulic cylinder 62, and the other end of the inner rod 74 is located on the outside of the corresponding outer cylinder 71 and is fixedly connected to the rack 77. The gear 76 is fixedly sleeved on the rotating seat 5, and the gear 76 and the rack 77 are meshed with each other. When the telescopic end of the hydraulic cylinder 62 is extended, it can drive the threaded sleeve 66 to move, so that the threaded sleeve 66 squeezes the inner rod 74 located on the inner top surface of the frame 1. When the inner rod 74 is squeezed, it can drive the sliding plug 72 to move. When the sliding plug 72 moves, it can press the gas in the outer cylinder 71 located on the inner top surface of the frame 1 into the other outer cylinder 71 through the connecting pipe 75. When the gas enters the other outer cylinder 71, it can push the other sliding plug 72 to move, which makes the other inner rod 74 move accordingly, thereby causing the rack 77 to move. When the rack 77 moves, it can drive the gear 76 to rotate, and the gear 76 can drive the rotating seat 5 to rotate, thereby causing the movable clamp 3 to rotate. The fixed fixed clamp 2 and the rotating movable clamp 3 can jointly complete the torsion test of the flexible circuit board.

[0026] The specific working principle of this utility model is as follows:

[0027] When testing the flexible circuit board, the staff first fixes the two ends of the flexible circuit board on the fixed fixture 2 and the movable fixture 3 respectively. When performing a tensile test on the flexible circuit board, the staff makes the telescopic end of the hydraulic cylinder 62 face downward. At this time, the threaded sleeve 66 is facing the threaded column 68. The staff rotates the threaded sleeve 66. When the threaded sleeve 66 rotates, it can drive the screw rod 65 to rotate. When the screw rod 65 rotates, it can move downward, and the threaded sleeve 66 will also move downward until the threaded sleeve 66 is screwed on the threaded column 68. At this time, the threaded sleeve 66 and the threaded column 68 play a connecting role between the hydraulic cylinder 62 and the lifting seat 67. After the connection is completed, the staff starts the hydraulic cylinder 62, so that the hydraulic cylinder 62 drives the lifting seat 67 to move upward through the fixed rod 63, the screw rod 64, the threaded sleeve 66 and the threaded column 68. When the lifting seat 67 moves upward, it can drive the movable fixture 3 to move upward through the rotating seat 5. When the movable fixture 3 moves upward, it can cooperate with the fixed fixture 2 to perform a tensile test on the flexible circuit board;

[0028] When a torsion test of the flexible circuit board is required, the staff rotates the threaded sleeve 66 in the opposite direction until the threaded sleeve 66 is separated from the threaded column 68, thereby releasing the connection between the hydraulic cylinder 62 and the lifting seat 67. Then the staff rotates the mounting frame 61 so that the mounting frame 61 and the hydraulic cylinder 62 rotate 180 degrees until the telescopic end of the hydraulic cylinder 62 faces upward. At this time, the threaded sleeve 66 is facing the inner rod 74 located on the inner top surface of the frame 1. Then, the staff starts the hydraulic cylinder 62. When the telescopic end of the hydraulic cylinder 62 extends, it can drive the threaded sleeve 66 to move, so that the threaded sleeve 66 squeezes the inner rod 74 located on the inner top surface of the frame 1. When the inner rod 74 is squeezed, it can drive the slide plug 72 to move. When the slide plug 72 moves, it can press the gas in the outer cylinder 71 located on the top surface of the frame 1 into the other outer cylinder 71 through the connecting pipe 75. When the gas enters the other outer cylinder 71, it can push the other slide plug 72 to move, which makes the other inner rod 74 move accordingly, thereby causing the rack 77 to move. When the rack 77 moves, it can drive the gear 76 to rotate, and the gear 76 can drive the rotating seat 5 to rotate, thereby causing the movable clamp 3 to rotate. The fixed fixed clamp 2 and the rotating movable clamp 3 can jointly complete the torsion test of the flexible circuit board.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
