DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 6 As shown, a circuit board testing device includes a support plate 11, a motor 14, and a tester body 23. The support plate 11 is horizontally arranged and has support legs 12 evenly connected to its lower side. The motor 14 is horizontally mounted on the upper side of the support plate 11 via a fixed plate 13. The output end of the motor 14 is coaxially connected to a rotating shaft 16, and a rotating disk 17 is coaxially connected to the rotating shaft 16. The edge of the rotating disk 17 is evenly distributed with a circle of through slots 17a, each of which is provided with a clamping structure for clamping the circuit board to be tested. The side of the rotating disk 17 is provided with a discharge structure for unloading the tested circuit board. The tester body 23 is centrally mounted on the top of the fixed plate 13. The motor 14 drives the rotating shaft 16 and the rotating disk 17 to intermittently rotate a certain angle, thereby rotating the clamped circuit boards to be tested one by one to directly below the tester body 23, and rotating the tested circuit boards one by one to the position of the discharge structure.

[0023] In this embodiment, the clamping structure includes a connecting bar 18 and a clamping bar 20. A pair of connecting bars 18 are parallelly connected to either side of the through-slot 17a. A connecting post 19 is slidably connected to the center of the connecting bar 18. Two clamping bars 20 are provided with a pair of connecting posts 19, each connected to a corresponding pair of connecting posts 19. Each clamping bar 20 has a clamping slot 20a on its side. A compression spring 21 is sleeved between the connecting posts 19 and the clamping bars 20. A pair of guide posts 22 are symmetrically connected to each end of the clamping bar 20, and the guide posts 22 are slidably connected to the connecting bar 18. When a circuit board is placed between the pair of clamping bars 20, the elastic force of the compression springs 21 on both sides clamps the board between the pair of clamping slots 20a.

[0024] In this embodiment, the unloading structure includes a telescopic cylinder 26 and an unloading rack 27. The telescopic cylinder 26 is horizontally mounted to the side of the fixed plate 13 via a fixed frame 25. The unloading rack 27 is a C-shaped structure mounted to the telescopic end of the telescopic cylinder 26. A pair of wedge blocks 28 are symmetrically mounted at each end of the unloading rack 27. Guide rods 29 are vertically connected to the sides of the unloading rack 27 and are slidably connected to the fixed frame 25. When a clamping structure with a circuit board rotates to the side of the unloading rack 27, the extension of the telescopic cylinder 26 drives the pair of wedge blocks 28 in front to open the pair of clamping bars 20. The unloading rack 27 moves backward and pushes the inspected (good) circuit boards into the collection box 31 at the rear. Conversely, the contraction of the telescopic cylinder 26 drives the pair of wedge blocks 28 in the rear to open the pair of clamping bars 20. The unloading rack 27 moves forward and pushes the inspected (defective) circuit boards into the collection box 31 at the front.

[0025] In this embodiment, a controller 15 is provided above the motor 14. A control circuit 24 extends from the side of the controller 15 and electrically connects the control circuit 24 to the motor 14, the tester body 23, and the telescopic cylinder 26. The controller 15 controls the motor 14, the tester body 23, and the telescopic cylinder 26 via the control circuit 24.

[0026] In this embodiment, a pair of placement plates 30 are connected to the upper side of the support plate 11. A collection box 31 is detachably connected to the upper side of each placement plate 30. Both collection boxes 31 are located below the unloading rack 27 and symmetrically distributed on the left and right sides of the rotating disk 17. One collection box 31 collects circuit boards that have been tested as good, while the other collection box 31 collects circuit boards that have been tested as defective.

[0027] In this embodiment, a buffer plate 32 is installed obliquely in each collection box 31. When the inspected circuit boards are separated from the clamping structure, they are buffered by the buffer plate 32 before sliding into the collection box 31, preventing them from falling directly into the collection box 31 and being damaged or broken.

[0028] How this test setup for circuit boards works:

[0029] Motor 14 drives rotating shaft 16 and rotating disk 17 to intermittently rotate a certain angle, moving the clamped circuit boards to be tested one by one directly below the tester main body 23, where they are inspected. The inspected circuit boards are then rotated one by one to the unloading mechanism. Telescopic cylinder 26 then extends and retracts, pushing the inspected good and defective circuit boards into corresponding collection bins 31. Furthermore, during idle periods, staff can insert the unused circuit boards into the unused clamping mechanism. This reduces manual labor, enabling automated post-test sorting, improving test efficiency, and saving manpower.

[0030] Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
