The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] This utility model provides a control board optical inspection machine, the structure of which is as follows: Figures 1-4 As shown, the device includes a workbench 1, on which a detection assembly 5 is mounted, with a first side plate 2 and a second side plate 3 fixed at both ends of its top surface. A frame 4 is provided between the first side plate 2 and the second side plate 3, with a through hole 14 and a slot 15 on the inner side of the first side plate 2. A bearing 20 is fixed on the inner side of the second side plate 3. A first rotating rod 6 and a second rotating rod 7 are fixed at both ends of the frame 4, and connecting plates 8 are provided on both sides. The first rotating rod 6 passes through the through hole 14 and is connected to a first gear 16. A second gear 19 is movably connected to the side of the second rotating rod 7, and its other end is connected to the bearing 20. Two sliding rods 9 are fixed on the inner sides of the two connecting plates 8. The sliding rods 9 are slidably connected to the frame 4, and their other ends are fixed to a clamping plate 10 located in the frame 4. A first motor 17 is installed in the slot 15, and its output end is connected to a third gear that meshes with the first gear 16. Wheel 18; A first L-shaped rod 11 and a second L-shaped rod 29 are respectively provided above and below the frame 4. The first L-shaped rod 11 and the second L-shaped rod 29 are fixed to the two connecting plates 8 via connecting rods 12, and several racks 13 meshing with them are fixed to the end face near the second gear 19. A horizontally arranged first cylinder 31 is also installed on the frame 4, its piston rod connected to a moving block 30. The moving block 30 is fixed to the side of the first L-shaped rod 11. The piston rod of the first cylinder 31 drives the first L-shaped rod 11 to move. Under the meshing transmission of the several racks 13 and the second gear 19, the two connecting plates 8 drive the two clamping plates 10 to move inward, clamping and securing the control board. At this time, the output end of the first motor 17 drives the third gear 18 to mesh with the first gear 16, causing the frame 4 to rotate and rotate the control board to flip it. Using a control board optical inspection machine, it can automatically flip to inspect both the top and bottom surfaces of the control board. The design is reasonable and easy to promote.

[0022] Specifically, the detection component 5 includes a horizontal plate 501 and a vertical plate 506. The top of the horizontal plate 501 has a first groove 502, and a second motor 503 is mounted on its side. The output end of the second motor 503 extends into the first groove 502 and is connected to a first screw 504. The side of the vertical plate 506 has a second groove 507, and a first limiting block 505, located in and adapted to the first groove 502, is fixed at its bottom. A second cylinder 508 is fixed to the side wall of the second groove 507, and its piston rod is connected to a movable block 509. A moving plate 510 is fixed to the side of the movable block 509. A third groove 511 is opened at the bottom of the moving plate 510, and a first limiting block 504 is mounted on its side. The third motor 512 has an output end that extends into the third groove 511 and is connected to a second screw 513. The second screw 513 has a threaded connection on its side to a second limiting block 514 that is compatible with the third groove 511. The bottom end of the second limiting block 514 is fixed to a CCD camera module 516 by a mounting rod 515. The output end of the second motor 503 drives the first screw 504 to rotate, and the third motor 512 drives the second screw 513 to rotate, so that the CCD camera module 516 can move horizontally. Then, the piston rod of the second cylinder 508 drives the CCD camera module 516 to move downward to perform optical detection on the control board.

[0023] Furthermore, the CCD camera module 516 is located above box 4.

[0024] Furthermore, each of the clamping plates 10 has a fourth groove 21 on its inner side and two clamping blocks 22. A movable rod 23 is fixed in the fourth groove 21. A slider 24 that is slidably connected to the movable rod 23 is fixed on one side of each of the two clamping blocks 22, and the other side is arc-shaped. The slider 24 is connected to the inner wall of the fourth groove 21 by a spring 25 that surrounds the side of the movable rod 23, thereby applying a vertical clamping force to the control plate to further fix it.

[0025] Furthermore, the second rotating rod 7 has an annular groove 26 on its side, and the inner wall of the second gear 19 is fixed with a slip ring 27 located in the annular groove 26 and slidably connected thereto, which is used to support the stable rotation of the second gear 19.

[0026] Furthermore, pads 28 are fixed at the four corners of the bottom of the workbench 1 to provide support.

[0027] The working principle of this utility model is as follows: After the top surface of the control board is inspected, the first cylinder 31 is started, and its piston rod drives the first L-shaped rod 11 to move. At this time, under the meshing transmission of several racks 13 and the second gear 19, the two connecting plates 8 drive the two clamping plates 10 to move inward and clamp the control board. Then, the first motor 17 is started, and its output end drives the third gear 18 to mesh with the first gear 16, so that the square frame 4 drives the control board to rotate and flip. Finally, the second motor 503 and the third motor 512 are started. The output end of the second motor 503 drives the first screw 504 to rotate and the third motor 512 drives the second screw 513 to rotate, so that the CCD camera module 516 can move horizontally. Then, the piston rod of the second cylinder 508 drives the CCD camera module 516 to move downward to perform optical inspection on the bottom surface of the control board.

[0028] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
