An internal turning device groove 2 is opened at one end of the workbench 1; a first fixed block 3 is fixedly connected inside the workbench 1 at the bottom of the turning device groove 2; a sliding rack 4 is slidably connected to the top end of the first fixed block 3; one end of the first fixed block 3 is fixedly connected to a mounting plate 5; a rotating rod 6 is rotatably connected inside the mounting plate 5; a first transmission gear 7 is fixedly connected to the outer side of the rotating rod 6; the first transmission gear 7 is meshed with the sliding rack 4; a connecting plate 8 is fixedly connected to the outer side of the other end of the first transmission gear 7, and a fixed box 9 is fixedly connected to one end of the connecting plate 8; a clamping frame 10 is fixedly connected to the other end of the fixed box 9. During operation, when it is necessary to conduct a reverse test on the circuit board to be tested, by sliding the sliding rack 4 above the first fixed block 3, the meshed first transmission gear 7 is driven to rotate, and then the rotating rod 6 is driven to rotate, so that the connecting plate 8 drives the fixed box 9 and the clamping frame 10 to turn 180 degrees. In this step, when it is necessary to conduct a reverse test on the circuit board to be tested, through the sliding movement of the sliding rack 4, the first transmission gear 7 and the connecting plate 8 are driven to rotate, so that the fixed box 9 and the clamping frame 10 turn the circuit board to be tested 180 degrees, making its reverse side face up, which is convenient for reverse testing. Since there is no need to manually turn the circuit board, the operation time and labor cost are reduced, and the testing efficiency and operation convenience are improved.

[0026] As Figure 2 and Figure 3 shown, a second fixed block 11 is fixedly connected to one side of the sliding rack 4; a connecting rod 12 is fixedly connected to the central position of the second fixed block 11; a first telescopic cylinder 13 is fixedly connected to a position of the mounting plate 5 far from the first transmission gear 7; the output end of the first telescopic cylinder 13 is fixedly connected to a connecting block 14; limiting blocks 15 are fixedly connected to both ends of the first fixed block 3. During operation, by starting the first telescopic cylinder 13, the connecting block 14 is driven to stretch back and forth. The second fixed block 11 is driven to slide above the first fixed block 3 through the connecting rod 12, and one side of the sliding rack 4 is slid to the position of the limiting block 15. In this step, by starting the first telescopic cylinder 13 to drive the connecting block 14 to stretch, the second fixed block 11 is driven to slide through the connecting rod 12, which improves the linkage effect of the device. At the same time, through the limiting effect of the limiting block 15, the accuracy and stability of the mechanical action are ensured.

[0027] As Figure 4As shown, the bottom end of the fixed box 9 is fixedly connected to the driving motor 16; the output end of the driving motor 16 is fixedly connected to a second driving gear 17; the outer side of the second driving gear 17 is meshed with a driving chain 18; the other side inside of the driving chain 18 is meshed with a threaded rod 19; the threaded rod 19 is rotatably connected to the clamping frame 10; both ends of the threaded rod 19 are threadedly connected with threaded blocks 20; one side of the threaded block 20 is fixedly connected to a clamping plate 21. During operation, when clamping the circuit board to be tested, by starting the driving motor 16, the second driving gear 17 is driven to rotate, and then the threaded rod 19 is driven to rotate inside the clamping frame 10 through the driving chain 18 in meshing relationship with it, so that the threaded blocks 20 move up and down to clamp the circuit board to be tested. In this step, when clamping the circuit board to be tested, by the rotation of the threaded rod 19, the threaded blocks 20 are driven to move up and down on the threaded rod 19, and the circuit board to be tested can be clamped, ensuring the stability during flipping, reducing the possibility of displacement during the test, which may lead to deviation of the test data, and improving the accuracy and reliability of the test.

[0028] As Figure 3 shown, both ends inside of the clamping frame 10 are fixedly connected with fixing columns 22, and both ends of the fixing columns 22 are fixedly connected with sliding plates 23; the sliding plates 23 are fixedly connected to the clamping plates 21. During operation, during the clamping process of the circuit board, through the structural cooperation of the fixing columns 22 and the sliding plates 23, the clamping plates 21 are limited, further improving the stability and reliability of clamping.

[0029] As Figure 3 shown, the bottom end of the clamping plate 21 is fixedly connected with a rubber pad 24. During operation, during the clamping process, through the action of the rubber pad 24, the pressure of the clamping plate 21 on the circuit board is effectively reduced. In this step, part of the pressure is absorbed by the rubber pad 24, reducing the possibility of the circuit board being deformed or damaged due to excessive pressure, and ensuring the normal progress of the test process.

[0030] As Figure 5As shown, a fixed rear plate 25 is fixedly connected to the top end of the workbench 1; one end of the fixed rear plate 25 is fixedly connected to a fixing plate 26; a second telescopic cylinder 27 is fixedly connected to the bottom end of the fixing plate 26; the output end of the second telescopic cylinder 27 is fixedly connected to a test plate 28; a plurality of detection columns 29 are fixedly connected to the bottom end of the test plate 28. During operation, when it is necessary to test the circuit board, by starting the second telescopic cylinder 27, the test plate 28 is driven to move downward, and then the detection columns 29 at the bottom end of the test plate 28 are driven to move downward. In this step, when it is necessary to test the circuit board, by starting the second telescopic cylinder 27 to drive the detection columns 29 to move downward. This semi-automated test process helps to reduce human errors, improve the accuracy and consistency of the test. By reducing the complex or repetitive tasks that operators need to perform, it helps to reduce the work burden and improve the overall work efficiency.

[0031] As Figure 1 shown, a plurality of shock pads 30 are fixedly connected to the bottom end of the workbench 1. During operation, when the circuit board is being tested, through the function of the shock pads 30, the vibration energy generated during the operation of the equipment can be effectively absorbed, ensuring the accuracy of the test and the stability of the equipment, and further extending the service life of the equipment.

[0032] Working principle: During operation, when it is necessary to perform a reverse test on the circuit board to be tested, by sliding the sliding rack 4 above the first fixed block 3, the first transmission gear 7 meshed with it is driven to rotate, and then the rotating rod 6 is driven to rotate, so that the connecting plate 8 drives the fixed box 9 and the clamping bracket 10 to turn 180 degrees. In this step, when it is necessary to perform a reverse test on the circuit board to be tested, through the sliding movement of the sliding rack 4, the first transmission gear 7 and the connecting plate 8 are driven to rotate, so that the fixed box 9 and the clamping bracket 10 turn the circuit board to be tested 180 degrees, so that its reverse side faces upward, which is convenient for reverse testing. Since there is no need to manually turn the circuit board, the operation time and labor cost are reduced, and the testing efficiency and operation convenience are improved. By starting the first telescopic cylinder 13, the connecting block 14 is driven to stretch back and forth, and the second fixed block 11 is driven to slide above the first fixed block 3 through the connecting rod 12, and one side of the sliding rack 4 is slid to the limit block 15. In this step, by starting the first telescopic cylinder 13 to drive the connecting block 14 to stretch, and driving the second fixed block 11 to slide through the connecting rod 12, the linkage effect of the device is improved. At the same time, through the limiting effect of the limit block 15, the accuracy and stability of the mechanical action are ensured. When clamping the circuit board to be tested, by starting the drive motor 16, the second transmission gear 17 is driven to rotate, and then the threaded rod 19 is driven to rotate inside the clamping bracket 10 through the transmission chain 18 engaged with it, so that the threaded block 20 moves up and down to clamp the circuit board to be tested. In this step, when clamping the circuit board to be tested, the threaded block 20 is driven to move up and down on the threaded rod 19, and the circuit board to be tested can be clamped, ensuring the stability during flipping and reducing the possibility of test data deviation caused by displacement that may occur during the test, improving the accuracy and reliability of the test. During the clamping process of the circuit board, through the structural cooperation of the fixed column 22 and the sliding plate 23, the clamping plate 21 is limited, further improving the stability and reliability of the clamping. During the clamping process, through the action of the rubber pad 24, the pressure of the clamping plate 21 on the circuit board is effectively reduced. In this step, part of the pressure is absorbed by the rubber pad 24, reducing the possibility of the circuit board being deformed or damaged due to excessive pressure, ensuring the normal progress of the test process. When it is necessary to test the circuit board, by starting the second telescopic cylinder 27, the test board 28 is driven to move downward, and then the detection column 29 at the bottom of the test board 28 is driven to move downward. In this step, when it is necessary to test the circuit board, by starting the second telescopic cylinder 27 to drive the detection column 29 to move downward. This semi-automatic test process helps to reduce human errors, improve the accuracy and consistency of the test. By reducing the complex or repetitive tasks that the operator needs to perform, it helps to reduce the work burden and improve the overall work efficiency. When the circuit board is being tested, through the action of the shock-absorbing pad 30,It can effectively absorb the vibration energy generated during the operation of the device, ensuring the accuracy of the test and the stability of the device, and further extending the service life of the device.
