DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 A circuit board optical inspection platform includes: a platform base 1, a column 2, an optical microscope 3 for observing fine circuits on a circuit board, and a connector 4 arranged on the optical microscope 3. The platform base 1 is also provided with a shift component 5 and an adjustment component 6; a connecting frame 21 is provided on the column 2, and the column 2 is fixedly connected to the platform base 1 through the connecting frame 21 and bolts. The establishment of the column 2 can increase the height of the optical microscope 3, ensuring the observation effect of the optical microscope 3 on the circuit board.

[0023] The shift assembly 5 includes a connecting plate 51 for placing the circuit board, a guide rail 52 slidably connected to the platform base 1, a first screw rod 53 rotatably set on the guide rail 52, a second screw rod 54 rotatably set on the platform base 1, and a slider 55 slidably set on the guide rail 52 and fixedly connected to the connecting plate 51; the first screw rod 53 is threadedly connected to the slider 55, and the second screw rod 54 is threadedly connected to the guide rail 52, so that the first screw rod 53 and the second screw rod 54 can realize the movement of the circuit board in four directions of front, back, left and right, thereby meeting actual observation needs.

[0024] The adjustment assembly 6 includes a movable rod 61 movably set on the platform base 1, a first friction block 63 and a second friction block 66 fixedly mounted on the movable rod 61, a first connecting ring 64 fixedly connected to the second screw rod 54, a second connecting ring 65 and a first connecting shaft 68 rotatably set inside the platform base 1, a pulley group 67 for realizing transmission connection between the second connecting ring 65 and the first connecting shaft 68, a square rod 62 fixedly connected to the first connecting shaft 68, a transmission shaft 69 and a second connecting shaft 612 rotatably set inside the guide rail 52, a connecting gear 610 fixedly mounted on the transmission shaft 69, and an end gear 611 fixedly connected to the second connecting shaft 612. A cavity for passing the movable rod 61 is opened on the second screw rod 54. , and the movable rod 61 is located inside the cavity, and the first friction block 63 is provided with a first friction pattern for enhancing friction on the side close to the first connecting ring 64, and the second friction block 66 is also provided with a second friction pattern for enhancing friction on the side close to the second connecting ring 65. The guide rail 52 is provided with a hole for passing the square rod 62, and the square rod 62 is also slidably connected to the transmission shaft 69. The connecting gear 610 and the end face gear 611 are both located in the internal cavity of the guide rail 52, and the connecting gear 610 and the end face gear 611 are meshed and transmitted. The diameter of the inner hole of the first connecting ring 64 and the diameter of the inner hole of the second connecting ring 65 are both larger than the maximum diameter of the movable rod 61, which can ensure that the movable rod 61 can move flexibly to meet actual application requirements.

[0025] Working principle: Place the circuit board on the connecting plate 51 and start the optical microscope 3 to observe the tiny circuits on the circuit board. The optical microscope 3 is provided with a connector 4 connected to the display screen, which can magnify the observed image for the user to detect.

[0026] First, push the movable rod 61 so that the first friction block 63 fixed on the movable rod 61 contacts the first connecting ring 64 fixed on the second screw rod 54. At this time, under the action of the friction pattern on the side of the first friction block 63, a certain friction force can be formed between the first connecting ring 64, and then the movable rod 61 is rotated. The second screw rod 54 rotates synchronously inside the platform seat 1. Because the guide rail 52 set up on the platform seat 1 is threadedly connected with the second screw rod 54, after the second screw rod 54 rotates, the guide rail 52 will slide left and right, and the slider 55 on the guide rail 52 is fixedly connected to the connecting plate 51. The circuit board placed on the connecting plate 51 can slide left and right with the guide rail 52. Then pull the movable rod 61 outward, so that the second friction block 66 fixed at the end of the movable rod 61 can contact the second connecting ring 65. Under the action of the friction pattern on the side of the second friction block 66, a certain friction force can be formed between the second connecting ring 65. The friction force of the movable rod 61 is generated, and the second connecting ring 65 rotates synchronously after the movable rod 61 is rotated. Because the first connecting shaft 68 is connected to the second connecting ring 65 through the pulley group 67, and the square rod 62 is fixed on the first connecting shaft 68 and is slidably connected to the transmission shaft 69 set inside the guide rail 52, the transmission shaft 69 will rotate with the rotation of the second connecting ring 65. Because the connecting gear 610 fixed on the transmission shaft 69 is meshed with the end gear 611 fixed on the second connecting shaft 612, the second connecting shaft 612 rotates synchronously inside the guide rail 52, and the first screw rod 53 fixedly connected to the second connecting shaft 612 rotates synchronously. Because the slider 55 is slidably connected to the guide rail 52 and is also threadedly connected to the first screw rod 53, as the first screw rod 53 rotates, the slider 55 will drive the connecting plate 51 and the circuit board to slide back and forth, so as to achieve the purpose of observing different areas of the circuit board.
