Four clamping stations are arranged on the turntable 3. A test body 5 is fixedly connected to the top of the base 1. A circuit board testing station is arranged on the top of the test body 5. A controller 4 is fixedly connected to the front side of the test body 5.

[0026] In the utility model, the clamping station includes a placement groove 11 opened on the top of the turntable 3 and a nut 16 fixedly connected to the outer side of the turntable 3. The inner thread sleeve of the nut 16 is provided with a threaded rod 14. One end of the threaded rod 14 is rotatably connected to a clamping plate 12. One side of the clamping plate 12 is fixedly connected to a rubber pad 13. The circuit board is placed in the placement groove 11 on the right side. The threaded rod 14 is rotated by a hand wheel 15. Under the action of the nut 16, the threaded rod 14 rotates inward and drives the clamping plate 12 and the rubber pad 13 to move inward, so that the circuit board can be clamped and fixed in the placement groove 11, thereby ensuring the stability of the circuit board during testing and improving the accuracy of the test.

[0027] In the utility model, the clamping plate 12 and the rubber pad 13 are both slidably sleeved in the placement groove 11 , and the clamping plate 12 and the rubber pad 13 can be guided so that they do not rotate together with the threaded rod 14 .

[0028] In the utility model, the clamping plate 12 is rotatably arranged at one end of the threaded rod 14 through a bearing, and the other end of the threaded rod 14 is fixedly connected with a hand wheel 15, which is convenient for rotatably connecting the clamping plate 12 to one end of the threaded rod 14 and facilitating the rotation of the threaded rod 14.

[0029] In the utility model, the station switching assembly includes a driving motor 17 fixedly connected to the inner wall of the bottom of the cover body 2, and a rotating shaft 19 rotatably connected between the cover body 2 and the base 1. The output shaft of the driving motor 17 is fixedly connected with a driving tooth 18, and the outer fixed sleeve of the rotating shaft 19 is provided with a driven tooth 20. The driving tooth 18 is meshed with the driven tooth 20. The turntable 3 is fixedly connected to the top of the rotating shaft 19. The driving motor 17 drives the driving tooth 18 to rotate, and the driving tooth 18 drives the driven tooth 20 and the rotating shaft 19 to rotate. The rotating shaft 19 drives the turntable 3 to rotate 90 degrees, thereby achieving the purpose of switching the four clamping stations. The circuit board to be tested can be rotated to the bottom of the detection needle 8 for testing, and the circuit board after the test can be rotated out from the bottom of the detection needle 8 for removal.

[0030] In the utility model, an annular groove is provided at the bottom of the turntable 3, and four guide posts 21 are fixedly connected to the top of the base 1. The four guide posts 21 are slidably sleeved in the annular groove to guide the turntable 3 and make its rotation more stable.

When the switching is completed, the electromagnet 10 can be energized to adsorb and fix the annular iron 9, thereby ensuring the stability of the turntable 3 and avoiding deflection that is not conducive to the test of the circuit board.

[0033] When the circuit board is in the placement groove 11 on the right, the threaded rod 14 is rotated by the hand wheel 15. Under the action of the nut 16, the threaded rod 14 rotates inward and drives the clamping plate 12 and the rubber pad 13 to move inward, so that the circuit board can be clamped and fixed in the placement groove 11, so as to ensure the stability of the circuit board during the test and improve the accuracy of the test. The driving motor 17 drives the rotation of the active gear 18, and the active gear 18 drives the rotation of the driven gear 20 and the rotating shaft 19.

When the placement groove 11 with the circuit board clamped is rotated to the bottom of the pressure plate 7, the cylinder 6 is started, and the cylinder 6 drives the pressure plate 7 and the detection needle 8 is moved downward to test the circuit board, and during the test, the circuit board can be clamped in the clamping station on the right synchronously, so that the clamping can be carried out while testing, which improves the test efficiency. When the test is completed, the pressure plate 7 is moved upward and the turntable 3 is rotated 90 degrees again, so that the tested circuit board is rotated out from under the pressure plate 7, and the circuit board to be tested is rotated to under the pressure plate 7 for testing. At this time, the circuit board that has been tested can be disassembled and taken out from the front placement groove, and then the circuit board can be clamped on the clamping station on the right, so that the circuit board can be clamped and placed while the circuit board is tested, which greatly improves the test efficiency.
