[0030] like Figure 2 As shown, the front of the test bench 1 in the embodiment of the utility model is embedded with a power switch 11 and an emergency stop switch 12, and a start button 13 is respectively embedded at both ends of the test bench 1. The power switch 11 is connected to the power converter through a connecting line, and the emergency stop switch 12 and the start button 13 are respectively connected to the control main board through connecting lines. The emergency stop switch 12 is an emergency braking device that can quickly cut off the power supply when the test is abnormal or dangerous to protect the safety of equipment and personnel. By setting a double start button 13, the accuracy of starting the test program can be improved to avoid accidental touch.
[0031] Preferably, two handles 17 are installed at both ends of the test bench 1 in the embodiment of the utility model, and a supporting rubber seat 18 is fixed at each of the four corners of the bottom of the test bench 1. The handles 17 at both ends of the test bench 1 facilitate the user to move the entire fixture, and the supporting rubber seat 18 at the bottom ensures the stability of the fixture when it is placed, reducing the test error caused by vibration or external force.
[0032] like Figure 3 As shown, a plurality of countersunk holes 7 are provided on both sides of the placement slot 5 in the embodiment of the utility model to match the nickel sheets at both ends of the FPC product. The countersunk holes 7 can ensure that the nickel sheets of the FPC product can be stably placed during the test, prevent the product from being displaced or falling off during the test, and improve the accuracy and stability of the test. The depths of the countersunk holes 7 on both sides of the placement slot 5 can be set to different depths as needed, with the upper countersunk hole 7 sinking to a depth of 10 mm and the lower countersunk hole 7 sinking to a depth of 3.5 mm.

Press the start buttons 13 at both ends of the test bench 1 at the same time to start the test program. The pressing mechanism starts to work, and the pressing cylinder 15 drives the moving seat 16 to move the needle plate 3 downward, so that the test needle on the needle plate 3 contacts the test point of the FPC product. The control mainboard controls the test system to test the electrical performance of the FPC product, transfers the test data to the memory, and outputs the results to the external device or system through the communicator. After the test is completed, the pressing mechanism lifts the needle plate 3 and separates it from the contact with the FPC product. Check the test results and mark or process the unqualified products if necessary. Clean the test bench 1 and the continuous carrier board 4 to prepare for the next round of testing.
