The upper surface of the test platform 1 is provided with a first fixing groove 11, and a placement plate 4 is slidably installed inside the first fixing groove 11. Two sets of fixing plates 43 are provided on the upper surface of the placement plate 4. A second guide rod 432 is provided through one side of the fixing plate 43. One end of the second guide rod 432 is connected to a clamping plate 431. An electric push rod is installed on one side of the fixing plate 43. This setting uses the operation of the electric push rod to move the clamping plate 431, and when it moves, it can clamp the PCBA motherboard placed on the placement plate 4. This can ensure its stability and avoid its movement, which would affect the test. At the same time, the position of the placement plate 4 can be adjusted by moving it inside the first fixing groove 11, so that the PCBA motherboard can be tested at different positions.

[0029] The front surface of the test bench 1 is provided with a second fixing groove 12. A screw 331 is rotatably installed inside the second fixing groove 12. A moving block 34 is provided outside the screw 331. A moving plate 3 is installed on the front surface of the moving block 34. An mounting plate 31 is installed on the rear surface of the moving plate 3. A dust collection box 32 is installed on the upper surface of the mounting plate 31. This setup utilizes the operation of the dust collection fan 321 inside the dust collection box 32 to suck up the dust on the PCBA motherboard on the placement board 4. By moving the moving plate 3, the dust on the PCBA motherboard can be thoroughly sucked up and cleaned, thereby improving the accuracy of its testing.

[0030] like Figure 4 As shown, the first fixing groove 11 is also provided with two sets of first guide rods 42. The placement plate 4 is slidably installed on the outside of the two sets of first guide rods 42. The test platform 1 is equipped with a second cylinder 41 on the outside. The telescopic end of the second cylinder 41 is connected to the middle position of one side of the placement plate 4. This arrangement uses the operation of the second cylinder 41 to make the placement plate 4 move inside the first fixing groove 11 and be guided by the two sets of first guide rods 42. This ensures the stability of its movement and enables the automatic feeding of the PCBA motherboard on the placement plate 4.

[0031] like Figure 4 As shown, the fixed end of the electric push rod is installed on one side of the fixed plate 43, and the telescopic end of the electric push rod is connected to one side of the clamping plate 431. This arrangement uses the operation of the electric push rod to make the clamping plate 431 move on the placement plate 4, thereby automatically clamping the PCBA motherboard placed on the placement plate 4 to ensure its stability.

[0032] like Figure 2 As shown, a motor 33 is also installed on the outside of the test bench 1. The drive end of the motor 33 is connected to one end of the screw 331. The moving block 34 has a screw hole that is threadedly connected to the screw 331. This setting uses the operation of the motor 33 to make the screw 331 rotate inside the second fixed groove 12. The moving block 34 can be moved through the threaded connection between the screw 331 and the screw hole. When moving, the position of the dust collection box 32 can be adjusted, thereby achieving the purpose of thoroughly cleaning the dust on the PCBA motherboard.

[0033] like Figure 2 and Figure 3As shown, the lower surface of the mounting plate 31 has a dust suction hole 311 that communicates with the dust collection box 32. One side of the dust collection box 32 has an exhaust hole 322. The dust collection box 32 is also equipped with a dust collection fan 321. A dust collection bag 323 is provided on one side of the dust collection fan 321 inside the dust collection box 32. This arrangement utilizes the operation of the dust collection fan 321 to allow dust on the PCBA motherboard to enter the dust collection box 32 through the exhaust hole 322. After entering, the dust is collected by the dust collection bag 323, thus preventing the dust from affecting the PCBA motherboard.

[0034] The working principle of this utility model is as follows: When using this adjustable PCBA motherboard multi-functional test fixture, the PCBA motherboard to be tested is placed on the placement plate 4. After placement, the electric push rod on one side of the fixing plate 43 is activated, which moves the clamping plate 431 to clamp the PCBA motherboard. After clamping, the motor 33 is activated. When the motor 33 is working, the screw 331 will rotate. Since the screw 331 is threadedly connected to the screw hole inside the moving block 34, the moving plate 3 can be moved. During movement, the dust removal fan 321 inside the dust removal box 32 is activated, which allows dust on the PCBA motherboard to enter the dust removal box 32 through the suction hole 311. After entering, it is collected by the dust removal bag 323. After dust removal, the second cylinder 41 is activated, which causes the placement plate 4 to move inside the first fixing slot 11, thereby moving the PCBA motherboard below the test board 22. The operation of the first cylinder 21 causes the test board 22 to move down and contact the reserved test points on the PCBA motherboard to achieve the purpose of testing.
