As the electric telescopic rod 9 continues to extend, the circuit board 13 is squeezed into the first carrier plate 6. At this time, the first carrier plate 6 tests the circuit board 13. When the circuit board 13 in the first carrier plate 6 is tested, the circuit board 13 to be tested in the second carrier plate 7 can be taken out. When the circuit board 13 in the second carrier plate 7 is tested, the circuit board 13 to be tested in the first carrier plate 6 can be taken out, so that the circuit board 13 can be tested and taken out at the same time during the test, thereby saving the process of first powering off and then taking it out during the test of the circuit board 13, the test speed of the circuit board 13 is improved, the test time of the circuit board 13 is saved, and the test efficiency of the circuit board 13 is improved.

[0028] A motor 11 is fixedly mounted on the surface of the workbench 1 . The motor 11 is a conventional forward and reverse motor in the prior art. The output end of the motor 11 is fixedly connected to the rotating shaft 2 , and the motor 11 provides power for the rotation of the rotating shaft 2 .

[0029] A controller 12 is fixedly mounted on the surface of the workbench 1 . The controller 12 is located at one side of the motor 11 . The motor 11 is electrically connected to the controller 12 via a wire. The controller 12 is a conventional controller 12 in the prior art.

[0030] The electric telescopic rod 9 is electrically connected to the controller 12 via a wire.

[0031] A rubber pad 14 for protecting the surface of the circuit board 13 is fixedly connected to the bottom surface of the pressing plate 10 . The rubber pad 14 can protect the components on the surface of the circuit board 13 when the pressing plate 10 acts on the surface of the circuit board 13 .

[0032] The bottom surfaces of the first carrier plate 6 and the second carrier plate 7 are both provided with a groove 15, and a support plate 16 is arranged above the groove 15. The end surface of the support plate 16 is slightly lower than the end surface of the second carrier plate 7. A first spring 17 is elastically connected between the support plate 16 and the groove 15, and the end surface of the support plate 16 is slightly lower than the end surface of the second carrier plate 7. By placing the circuit board 13 on the surface of the support plate 16, the pressing plate 10 moves to squeeze the circuit board 13 into the carrier plate, and squeezes the support plate 16 to move. At this time, the first spring 17 is squeezed and compressed by the support plate 16. When the test of the circuit board 13 is completed, the pressing plate 10 moves away from the circuit board 13. At this time, the support plate 16 is reset under the action of the first spring 17, and the circuit board 13 pops out from the carrier plate, making it convenient and quick to take out the circuit board 13, further improving the speed of testing the circuit board 13.

[0033] One end of the first spring 17 is fixedly connected to the bottom surface of the slot 15 , and the other end of the first spring 17 is fixedly connected to the bottom surface of the support plate 16 . The support plate 16 is reset under the action of the first spring 17 , and the circuit board 13 pops out from the carrier board.

[0034] The utility model uses the following steps: When the integrated circuit test carrier is used to test the circuit board 13, the circuit board 13 is placed above the support plate 16 in the first carrier 6 and the second carrier 7, respectively, and the controller 12 is operated. The controller 12 controls the motor 11 to rotate forward, and the motor 11 rotates forward with the gear 3, thereby causing the gear plate 5 to move with the first carrier 6 and the second carrier 7. When the first carrier 6 moves to the bottom of the pressing plate 10, the controller 12 controls the electric telescopic rod 9 to extend, and the electric telescopic rod 9 extends and moves with the pressing plate 10 to act on the surface of the circuit board 13. As the electric telescopic rod 9 continues to extend, the circuit board 13 is squeezed into the first carrier 6, and the circuit board 1 3 moves into the carrier plate and squeezes the support plate 16 to move. At this time, the first spring 17 is squeezed by the support plate 16 and compressed. At this time, the first carrier plate 6 tests the circuit board 13. After the test is completed, the electric telescopic rod 9 retracts and resets the pressure plate 10. At this time, the support plate 16 is reset under the action of the first spring 17. At this time, the circuit board 13 pops out from the carrier plate, and the motor 11 reverses and rotates the gear 3, thereby causing the gear plate 5 to move and move the first carrier plate 6 and the second carrier plate 7. When the second carrier plate 7 moves to the bottom of the pressure plate 10, the controller 12 controls the electric telescopic rod 9 to extend. The electric telescopic rod 9 extends and moves with the pressure plate 10 to act on the surface of the circuit board 13. As the electric telescopic rod 9 is extended, the pressure plate 10 moves to the surface of the circuit board 13. The retractable rod 9 continues to extend, and the circuit board 13 is squeezed into the second carrier plate 7 for testing. During the process of squeezing the circuit board 13 into the second carrier plate 7, the circuit board 13 in the first carrier plate 6 has been tested, and the circuit board 13 in the first carrier plate 6 is taken out and replaced with the circuit board 13 with the test. The above steps are repeated reciprocally. This scheme rotates the gear 3 through the forward rotation of the motor 11, thereby causing the gear plate 5 to move with the first carrier plate 6 and the second carrier plate 7. When the first carrier plate 6 moves to the bottom of the pressing plate 10, the controller 12 controls the electric telescopic rod 9 to extend, and the electric telescopic rod 9 extends and moves with the pressing plate 10 to act on the surface of the circuit board 13. As the electric telescopic rod 9 continues to extend, the electric The circuit board 13 is squeezed into the first carrier board 6. At this time, the first carrier board 6 tests the circuit board 13. When the circuit board 13 in the first carrier board 6 is tested, the circuit board 13 to be tested in the second carrier board 7 can be taken out. When the circuit board 13 in the second carrier board 7 is tested, the circuit board 13 to be tested in the first carrier board 6 can be taken out. During the test of the circuit board 13, the circuit board 13 can be tested while being taken out, thereby saving the process of first powering off and then taking out the circuit board 13 during the test process of the circuit board 13. The test speed of the circuit board 13 is improved, the test time of the circuit board 13 is saved, and the test efficiency of the circuit board 13 is improved.

[0035] Example 2

[0036] When the first carrier plate 6 and the second carrier plate 7 move to the position directly below the pressure plate 10, the motor 11 stops, causing the circuit board 13 to deviate slightly under inertia. In order to reduce the deflection of the circuit board 13, the following solution is used to solve the problem.

[0037] See also Figures 1 to 5 The difference between the combined implementation basis is that a fixed plate 18 is fixedly installed in the middle of the surface of the workbench 1, and plate grooves 19 are opened on the two corresponding surfaces of the fixed plate 18. A guide rod 20 is slidably connected inside the plate groove 19. The guide rod 20 passes through the fixed plate 18, and both ends of the guide rod 20 are fixedly connected with movable blocks 21. A second spring 22 is elastically connected between any movable block 21 and the plate groove 19, and a connecting plate 23 is fixedly connected to the middle of the surface of the first carrier plate 6 and the second carrier plate 7.

[0038] The utility model uses the following steps: When the integrated circuit test carrier is in use, the first carrier 6 moves toward the bottom of the pressure plate 10, and the first carrier 6 moves with the support plate 16 and the circuit board 13. The movement of the first carrier 6 simultaneously moves the connecting plate 23 to squeeze the movable block 21, and then the movable block 21 moves with the guide rod 20 to squeeze the second spring 22. When the movable block 21 moves into the plate slot 19, the first carrier 6 stops moving when it reaches the bottom of the pressure plate 10. The movement principle of the second carrier 7 is the same as that of the first carrier 6, which increases the buffering of the circuit board 13 when it is stopped, thereby preventing the circuit board 13 from deflecting.
