[0002] The flexible circuit board electrical measuring device is mainly used to detect the electrical performance parameters of the flexible circuit board, such as resistance, capacitance, printed circuit board measurement, and the conductivity of the circuit board, to ensure that the circuit board has no short circuit, open circuit and other problems, thereby ensuring its normal operation. The flexible circuit board electrical measuring device uses electronic testing equipment to test the electrical performance of the flexible circuit board. During the test, the equipment will traverse the circuit of the test circuit board to check whether there are faults such as short circuit and open circuit, and measure key parameters such as resistance and capacitance.

[0003] Some existing flexible circuit board electrical testing devices connect the detection plate and the pressure plate through bolts, while some flexible circuit board electrical testing devices use a support plate without a buffer unit. The support plate provides rigid support for the flexible circuit board, and then performs the detection work of the flexible circuit board.

[0004] This type of flexible circuit board electrical measuring device has the following problems. For example, the detection plate and the pressure plate are connected by bolts, which makes the connection process of the detection plate and the pressure plate more cumbersome and inconvenient to replace the detection plate. The support plate has no buffer unit. Under the pressure of the pressure plate, the flexible circuit board and the support plate are more closely adsorbed, which is not convenient for the flexible circuit board material removal work.

The upper ends of the four adjusting rods are all rotatably connected to the same drive seat. The screw is rotatably connected to the upper end of the pressure plate.

A spring is fixedly connected between the movable seat and the laterally adjacent second slide groove to realize the resetting of the support plate and provide a buffering effect for the movement of the support plate.

[0014] Furthermore, the left and right ends of the upper surface of the pressure plate are fixedly connected with sliding columns, and the upper end of the contraction bin is provided with symmetrically distributed sliding openings, which are slidably connected to the vertically adjacent sliding columns to provide guidance for the movement of the pressure plate.

When the pressure plate pulls the detection plate to separate from the support plate, the spring pushes the support plate to return to its original position, facilitating the removal of the flexible circuit board.

The slide groove 41 is respectively arranged at the front and rear ends of the pressure plate 6. The left and right ends of the slide groove 41 are slidably connected with the sliding seat 42. The lower ends of the two longitudinally adjacent sliding seats 42 are fixedly connected to the upper end of the same clamping plate 44, and the clamping plates 44 are all installed in conjunction with the detection plate 7; the clamping mechanism 4 also includes an adjusting rod 43, a driving seat 45, a screw rod 46 and a knob 47. The adjusting rods 43 are all rotatably connected to the upper end of the sliding seat 42. The upper ends of the four adjusting rods 43 are all rotatably connected to the same driving seat 45. The screw rod 46 is rotatably connected to the upper end of the pressure plate 6. The interior of the driving seat 45 is threadedly connected to the middle part of the screw rod 46, and the upper end of the screw rod 46 is fixedly connected to the knob 47.

[0027] Among them, the buffer mechanism 5 is used for buffering and resetting the support plate 12. The buffer mechanism 5 includes a horizontal plate 51, a second slide 52, a movable seat 53, a buffer rod 54, a connecting seat 55 and a spring 56. The connecting seat 55 is respectively fixedly connected to the front and rear ends of the lower surface of the support plate 12. A cavity 3 is provided inside the electrical measuring table 1. The interior of the cavity 3 is fixedly connected with the horizontal plate 51. The front and rear ends of the horizontal plate 51 are both provided with a second slide 52. The interior of the second slide 52 is slidably connected with the movable seat 53. The upper end of the movable seat 53 is rotatably connected with the buffer rod 54. The upper end of the buffer rod 54 is rotatably connected to the vertically adjacent connecting seat 55. A spring 56 is fixedly connected between the movable seat 53 and the laterally adjacent second slide 52.

[0028] Among them: the left and right ends of the upper surface of the pressure plate 6 are fixedly connected with sliding columns 9, the upper end of the bundling chamber 2 is provided with symmetrically distributed sliding openings, and the sliding openings are slidingly connected with the vertically adjacent sliding columns 9, and the upper end of the bundling chamber 2 is provided with an electric push rod 10, and the telescopic end of the electric push rod 10 is fixedly connected with a connecting disk 14, and the lower end of the connecting disk 14 is rotatably connected to the upper end of the screw rod 46, and the input end of the electric push rod 10 is electrically connected to the output end of the main machine 13.

[0029] The working principle of this utility model is as follows:

[0030] During work, the personnel first place the electrical test table 1, the bundling bin 2 and other mechanisms stably in the horizontal working area. After they are placed stably, the personnel select the corresponding detection plate 7 according to the component distribution of the flexible circuit board to be electrically tested, and place the detection plate 7 on the lower end of the pressure plate 6. Then the personnel rotate the screw rod 46 through the knob 47. The rotation of the screw rod 46 causes the driving seat 45 to move upward. The upward movement of the driving seat 45 drives the upper ends of the four adjusting rods 43 to move upward, so that the lower ends of the adjusting rods 43 all pull the sliding seat 42 toward the center of the pressure plate 6. The sliding seats 42 all move toward the center of the pressure plate 6 in the corresponding slide groove 41. The inward sliding of the sliding seat 42 drives the vertically adjacent clamping plates 44 to move toward the center of the pressure plate 6, thereby achieving stable clamping of the detection plate 7.

[0031] After the clamping is stable, the personnel stops turning the knob 47, and then electrically connects the test probes 8 to the host 13 through the wires. Then the personnel places the flexible circuit board to be electrically tested on the corresponding position on the upper surface of the support plate 12, and then the personnel uses the host 13 to realize the operation of the electric push rod 10, and the telescopic end of the electric push rod 10 extends. The telescopic end of the electric push rod 10 pushes the screw rod 46 through the connecting disk 14, and then pushes the pressure plate 6 down. The slide columns 9 all slide downward inside the corresponding sliding mouths, providing a guide for the movement of the pressure plate 6. The downward movement of the pressure plate 6 drives the detection plate 7 to move downward, and the detection plate 7 drives the evenly distributed test probes 8 to contact the flexible circuit board. The detection plate 7 generates a downward thrust on the support plate 12, and the support plate 12 moves downward inside the guide rail 11. At the same time, the connecting seats 55 push the upper ends of the vertically adjacent buffer rods 54 to move downward, so that the lower ends of the buffer rods 54 push the moving seats 53 in the corresponding slide grooves 2 52 slides inside, and the moving seat 53 moves in the corresponding slide groove 2 52 in the direction away from the center of the horizontal plate 51, so that the laterally adjacent springs 56 are elastically stretched. The elastic force of the spring 56 reacts on the moving seat 53 and is finally transmitted to the support plate 12. The support plate 12 pushes the flexible circuit board to make close contact with the test probe 8. At the same time, the personnel adjusts the test parameters through the control key panel 15, and then the host 13 controls the operation of the test probe 8 to realize the electrical measurement of each component of the flexible circuit board, and displays the electrical measurement results through the host 13. After the electrical measurement is completed, the host 13 realizes the contraction of the telescopic end of the electric push rod 10. The contraction of the telescopic end of the electric push rod 10 drives the pressure plate 6 to move upward. The upward movement of the pressure plate 6 reduces the downward thrust exerted on the support plate 12 to zero. At the same time, the elastic force applied by the spring 56 to the support plate 12 causes the support plate 12 to return to its initial position, making it convenient for personnel to take out the flexible circuit board after electrical measurement.

[0032] It is worth noting that the test probe 8 disclosed in the above embodiment can be PA100-A2, the host 13 can be PY-H608, and the host 13 controls the test probe 8, the electric push rod 10 and the control key board 15 using methods commonly used in the prior art.

[0033] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
