[0022] like Figures 1 to 6 As shown, this utility model provides an aging test device for electronic components with automatic detection function, including a test platform 1. Fixed sleeve plates 2 are fixedly connected to the left and right sides of the rear end of the upper surface of the test platform 1. A crossbar 3 is movably sleeved on the inner surface of the fixed sleeve plate 2. A limit strip 7 is fixedly connected to the rear end of the crossbar 3. A connecting plate 4 located in front of the fixed sleeve plate 2 is fixedly connected to the front end of the crossbar 3. A connecting block 5 is movably connected to the front surface of the connecting plate 4. A cleaning brush 6 is fixedly connected to the front surface of the connecting block 5.

There is a first circular shaft 9, and an active rod 10 is fixedly sleeved on the outer surface of the first circular shaft 9. The other end of the active rod 10 is hinged to a driven rod 11, and the other end of the driven rod 11 is hinged to the middle of the lower surface of the limiting strip 7. When the operator starts the first power motor 8, the first circular shaft 9 and the active rod 10 will start to rotate. At this time, the other end of the active rod 10 will drive the driven rod 11, so that the driven rod 11 will start to rotate about the other end of the active rod 10 as the axis.

[0027] A limiting rod 23 is fixedly connected to the front side of the left surface of the top plate 22, and a first drive motor 24 is fixedly installed on the rear side of the left surface of the top plate 22. The other end of the output shaft of the first drive motor 24 is fixedly sleeved with a first single thread rod 25. The right ends of the limiting rod 23 and the first single thread rod 25 pass through the top plate 22 and the mounting plate 26 in sequence and extend to the right surface of the top plate 22. The outer surface of the limiting rod 23 is movably sleeved with the inner surface of the mounting plate 26, and the outer surface of the first single thread rod 25 is threadedly sleeved with the inner surface of the mounting plate 26. When the first drive motor 24 starts running, the first single thread rod 25 will start to rotate. At this time, the entire mounting plate 26 will start to move left and right along the inner surface of the top plate 22 and the outer surface of the limiting rod 23 under the drive of the first single thread rod 25.

[0028] The hollow block 28 has a second drive motor 31 fixedly mounted on its front surface.

When the second drive motor 31 starts running, the second single-threaded rod 32 will start to rotate. At this time, the entire sleeve block 29 will start to move back and forth along the inner surface of the hollow block 28 under the drive of the second single-threaded rod 32.

[0029] Working principle and usage process of this utility model:

[0030] First, the operator attaches the old circuit board to positioning plate 17 and positioning plate 18, then starts pneumatic cylinder 20. As pneumatic cylinder 20 operates, T-shaped clamp 19 begins to move towards the old circuit board. Finally, the old circuit board is clamped and fixed above the testing table 1 by T-shaped clamp 19 and positioning plate 18. Then, the operator starts motor 8 and motor 14. The operation of motor 8 causes the first circular shaft 9 and the drive rod 10 to rotate, while the other end of the drive rod 10... The end will drive the driven rod 11, causing the driven rod 11 to start rotating. Finally, the other end of the driven rod 11 will drive the limit bar 7, causing the limit bar 7 to move forward as a whole. In addition, the operation of the second power motor 14 will cause the second round shaft 15 and the driving rod 16 to start rotating. The rotation of the driving rod 16 will cause the connecting block 5 and the cleaning brush 6 to move left and right under the drive of the inner surface of the driving rod 16. Finally, under the combined action of the connecting block 5 and the cleaning brush 6, the dust on the old circuit board will be thoroughly cleaned.

[0031] Then, the operator starts the first drive motor 24, the second pneumatic cylinder 27, the detection probe 30, and the second drive motor 31. The operation of the first drive motor 24 causes the first single-threaded rod 25 to rotate, thereby causing the mounting plate 26 to move left and right. The operation of the second pneumatic cylinder 27 causes the hollow block 28 to move downward. The operation of the second drive motor 31 causes the second single-threaded rod 32 to rotate, thereby causing the socket block 29 to move back and forth. The operation of the second drive motor 31 can perform power-on testing on the solder joints of electronic components on the old circuit board. Finally, under the combined action of the mounting plate 26, the hollow block 28, and the socket block 29, the aging test of electronic components on the old circuit board is completed.
