[0002] With the progress of technology and the increase in electronic products, the manufacture and use of various circuit boards have also increased. After the existing circuit boards are produced, they all need to be detected to avoid the produced circuit boards not meeting the standards. The size of the circuit board is an important data that needs to be checked for the circuit board.

[0003] At present, the size detection of circuit boards generally uses a measuring ruler, but the measuring ruler can only detect the size in one direction at a time, and each detection of the measuring ruler needs to be re-aligned. Therefore, the detection of the measuring ruler is cumbersome and time-consuming, resulting in low detection efficiency of the circuit board. For this reason, we propose a circuit board detection device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a circuit board detection device, which can realize the synchronous measurement and detection of the size and thickness of the circuit board, reduce the measurement steps, thereby improving the detection efficiency. When the size detection component and the thickness detection component are used to detect the circuit board, it is not necessary to re-align with the circuit board every time, greatly improving the detection efficiency of the circuit board.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

Those skilled in the art can make similar extensions without departing from the connotation of the present invention.

[0026] Embodiment

[0027] Please refer to Figures 1 to 4 As shown, the present utility model provides a circuit board detection device, including:

[0028] A feeding component, including a conveyor rack 1. Above the top of the conveyor rack 1, there is a detection cover 2. On both inner walls of the detection cover 2 on both sides relative to the conveying direction of the conveyor rack 1, there are hinge-connected guide plates 9, and the guide plates 9 are combined to cover the port of the detection cover 2; the circuit board is placed on the conveyor rack 1 and thus conveyed to the bottom below the detection cover 2. When the circuit board enters the interior of the detection cover 2, it will first contact the guide plate 9 covering the port of the detection cover 2, and due to the size of the circuit board itself, it will push the guide plate 9 to hinge and rotate;

[0029] Further, at one end of the guide plate 9 away from the hinge point, there is a support plate 10 hinge-connected, and at the other end of the support plate 10, there is a limit slider 15 hinge-connected. The limit slider 15 is slidably connected to the inner wall of the detection cover 2 along the conveying direction of the conveyor rack 1;

[0030] Further, a limiting chute 16 is formed in the inner wall of the detection cover 2 along the conveying direction of the conveying rack 1. The limiting slider 15 is located inside the limiting chute 16 and is slidably connected to each other. A first spring 17 is connected between the end inner wall of the limiting slider 15 and the limiting chute 16. After the circuit board passes, the guiding plate 9 will be pushed by the first spring 17 to reset.

[0031] The dimension detection component includes a first scale plate 3. A first guiding hole 7 facing the guiding plate 9 is formed through the side wall of the detection cover 2. The first scale plate 3 penetrates through the first guiding hole 7 and is slidably connected to each other. One end of the first scale plate 3 is in contact with the guiding plate 9. The outer shape of the end of the first scale plate 3 in contact with the guiding plate 9 is a "T" shape. A second spring 8 is connected between the flange of the first scale plate 3 and the inner wall of the detection cover 2. The second spring 8 is sleeved on the outer surface of the first scale plate 3. Since the guiding plate 9 is pushed by the circuit board, the port of the detection cover 2 is hinged and rotated to open. Since the guiding plate 9 is extruded and pushed by the circuit board, the movement degree of the guiding plate 9 depends on the size of the circuit board. During the movement, the guiding plate 9 synchronously pushes the first scale plate 3, and the displacement travel distance of the first scale plate 3 is read, so as to calculate the size of the circuit board. After the guiding plate 9 automatically resets, the first scale plate 3 is immediately reset under the push of the second spring 8, which is beneficial to the recycling of dimension detection.

[0032] The thickness detection component includes a measuring block 5 and a second scale plate 6. A second guiding hole 4 is formed through the top surface of the detection cover 2. The measuring block 5 penetrates through the second guiding hole 4 and is slidably connected up and down with each other. The bottom surface of the measuring block 5 is flush with the top surface of the conveying rack 1. The second scale plate 6 is vertically connected to the top surface of the detection cover 2 and is located on both sides of the second guiding hole 4. When the circuit board is conveyed through the detection cover 2 by the conveying rack 1, the measuring block 5 will be displaced due to its own thickness. The second scale plate 6 reads the displacement travel distance of the measuring block 5, so as to calculate the thickness of the circuit board. The measuring block 5 will automatically reset under gravity, which is beneficial to recycling.

[0033] Further, a roller 11 is rotatably arranged on the bottom surface of the measuring block 5. The rotation direction of the roller 11 is consistent with the conveying direction of the conveying rack 1. The roller 11 is beneficial to reducing the frictional resistance when the circuit board passes through the bottom surface of the measuring block 5.

[0034] Furthermore, a positioning chute 12 is longitudinally formed on the outer surface of the second scale plate 6. A positioning column 13 is connected to the upper side wall of the measuring block 5. The positioning column 13 is located inside the positioning chute 12 and is slidably connected. A pointer 14 pointing to the second scale plate 6 is arranged on the end surface of the positioning column 13. The pointer 14 is beneficial to reading the displacement travel distance of the measuring block 5.

[0035] The above are only the preferred embodiments of the present utility model, which are illustrative rather than restrictive to the present utility model. Those skilled in the art understand that many changes, modifications, or even equivalents can be made to it within the spirit and scope defined by the claims of the present utility model, but all of them will fall within the protection scope of the present utility model.
