(When needed, the support plate 6 and the needle plate 5 can be directly replaced with the support plate 6 and the needle plate 5 corresponding to other model products to realize the sharing with the detection box 1 and improve the applicability of the testing device). A plurality of test needles 11 are fixedly connected to the upper end of the support plate 6. A plurality of first springs 9 are fixedly connected to the upper end of the support plate 6. One end of the first spring 9 far away from the support plate 6 is fixedly connected to a needle plate 5. The bottom end of the needle plate 5 is fixedly connected to a first sliding rod 18.

A sliding hole 14 is formed on the upper end surface of the needle plate 5. A first positioning plate 13 is slidably connected inside the sliding hole 14. A position adjusting mechanism is installed at the lower end of the first positioning plate 13, and the position adjusting mechanism is used to adjust the height of the first positioning plate 13; a detection position is formed among the first positioning plate 13, the second positioning plate 20 and the positioning column 12, and a plurality of needle holes 10 are all located inside the detection position. A PCBA circuit board 7 is placed inside the detection position, and the height of the PCBA circuit board 7 is greater than the heights of the first positioning plate 13, the second positioning plate 20 and the positioning column 12. During operation, with the mutual cooperation of the position adjusting mechanism and the feeding component of the utility model, it is not only convenient to place the PCBA circuit board 7 in the detection position formed by the first positioning plate 13, the second positioning plate 20 and the positioning column 12, but also convenient to take out the tested PCBA circuit board 7 from the detection position.

During operation, the pull rod 19 is pushed to the right, driving the moving block 23 to move along the second sliding rod 21 and compressing the second spring 22. At this time, the pull rod 19 will penetrate through the second positioning plate and gradually contact the PCBA circuit board 7, and push the PCBA circuit board 7 to the right until the PCBA circuit board 7 moves to the upper end of the first positioning plate 13.

[0025] Working principle:

[0026] In use, first control the operation of the position adjustment mechanism to drive the first positioning plate 13 to move downward until the top end of the first positioning plate 13 completely enters the sliding hole 14. Then, the staff can install the PCBA circuit board 7 from right to left in the detection position. The PCBA circuit board 7 is the circuit board used inside new energy vehicles. During the installation process, the staff can push the PCBA circuit board 7 to move leftward through the rectangular hole 8 until the left end of the PCBA circuit board 7 contacts the second positioning plate 20. After the two positioning columns 12 contact the front and rear ends of the PCBA circuit board 7, reverse-control the operation of the position adjustment mechanism to make the first positioning plate 13 move upward and reset to contact the right end face of the PCBA circuit board 7. At this time, the installation of the PCBA circuit board 7 is completed. The height of the installed PCBA circuit board 7 should be greater than the heights of the first positioning plate 13, the second positioning plate 20, and the positioning columns 12. Then control the operation of the hydraulic telescopic rod 3 to drive the pressure plate 4 to move downward until the pressure plate 4 presses on the upper end of the PCBA circuit board 7. Then, as the pressure plate 4 moves downward, it can press the needle plate 5 to move downward. The needle plate 5 moves downward to compress the first spring 9, and the test needle 11 passes through the needle hole 10 to contact the PCBA circuit board 7, and the detection system detects various functions of the PCBA circuit board 7 to achieve intelligent and automated testing operations on the PCBA circuit board 7. Until the testing is completed, reverse-control the hydraulic telescopic rod 3 to make the pressure plate 4 move upward and reset. At this time, under the action of the first spring 9, it can ensure that the needle plate 5 moves upward and resets, and at the same time, the test needle 11 disengages from the needle hole 10. Then control the operation of the position adjustment mechanism to make the first positioning plate 13 move downward back into the sliding hole 14, and then control the pushing component to operate to the right to make the PCBA circuit board 7 gradually move to the right until the PCBA circuit board 7 moves to a suitable position and presses on the upper end of the first positioning plate 13. Then the staff reverse-controls the operation of the position adjustment mechanism to control the first positioning plate 13 to move upward, so that the first positioning plate 13 pushes one end of the PCBA circuit board 7 to tilt upward, which is convenient for the staff to remove the PCBA circuit board 7.
