Description

Technical Field

If there is a problem with the product, it will cause serious consequences in the future use process. Finding the problem as early as possible can avoid a lot of unnecessary losses. When conducting a power-on test, the test needle is generally used to contact the test point of the circuit board for a conduction test.

[0050] Then the upper surface of the circuit board 51 is cleaned, the motor 27 drives the gear 1 26 to rotate, the gear 1 26 drives the gear 2 20 meshing therewith to rotate, the gear 1 26 drives the transmission component 1 12 to move, the gear 2 20 drives the transmission component 2 13 to move, the transmission component 2 13 and the transmission component 1 12 simultaneously drive the support rod 1 14 and the support rod 2 15 in the same way, the support rod 14 drives the card 1 17 to move, the support rod 2 15 drives the card 2 19 to move, the card 1 17 and the card 2 19 move relatively close to or relatively away from each other, when the card 1 17 and the card 2 19 are close to each other, the folding capsule 28 is squeezed, the gas in the folding capsule 28 enters the exhaust cavity 30 and is discharged from the blowing hole 31 to clean the surface of the circuit board 51, when the card 1 17 and the card 2 19 are away from each other, the folding capsule 28 is stretched, and the external gas enters the folding capsule 28 through the blowing hole 31 and the exhaust cavity 30.

[0051] When one group of circuit boards 51 is tested and the next group of circuit boards 51 to be tested needs to be moved, the hydraulic rod 2 45 works to drive the toggle plate 46 to descend. When the support rod 2 15 and the support rod 1 14 move closer to each other, the support plate 32 can drive the toggle assembly to move, and the toggle plate 46 pushes the circuit board 51. The circuit board 51 moves to the lower end of the test pin 53 in turn. When the support rod 2 15 and the support rod 1 14 move away from each other, the hydraulic rod 2 45 works to drive the toggle plate 46 to rise, and the hydraulic rod 3 49 works to push the lifting plate 50 upward. The lifting plate 50 pushes the circuit board 51 to move up and extend out of the slot hole 3 48. The toggle plate 46 moves to the rear side of the circuit board 51 extending out of the slot hole 3 48, so as to facilitate pushing the circuit board 51.
