In the prior art, a laser displacement sensor can be used to detect whether there is PCB board material. By measuring the threshold value, if it is lower than the threshold value, the device will give an alarm reminder;
[0003] Most PCB boards are placed on the base. By manually aiming the holes on the PCB board at the position of the laser by personnel and then conducting detection. However, through actual use, it is found that when personnel aim at the holes, since most of the holes on the PCB board are relatively small and multiple groups of holes are arranged at equal distances, it may be necessary for personnel to continuously aim before they can align for detection;
[0004] Moreover, there are many holes on the PCB board. Although there is a certain distance between them, personnel cannot ensure that they can accurately move to the position of the next group of holes for detection when holding the board by hand. Therefore, during detection, due to difficult calibration, it may take a lot of time to align and then use. For this reason, we propose a detection device for facilitating the rapid detection of PCB boards to solve the above problems. Content of the Utility Model

Therefore, during detection, due to difficult calibration, it may take a lot of time to align and then use.
[0006] To achieve the above purpose, the utility model provides the following technical scheme: A detection device for facilitating the rapid detection of PCB boards, including a base, a PCB board, a laser displacement sensor and a hinge frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1 - 5 , an embodiment provided by the present invention: a detection device for facilitating the rapid detection of a PCB board, including a base 1, a PCB board 3, a laser displacement sensor 4, and a hinge frame 17. A placement plate 2 is placed on the upper end of the base 1, and a PCB board 3 is arranged on the upper end of the placement plate 2. A laser displacement sensor 4 is arranged at the rear end of the base 1. Fixing plates 5 are fixedly connected to the front and rear of the upper end of the placement plate 2, and rollers 10 are installed inside both groups of fixing plates 5. A hinge frame 17 is installed at the left end of the placement plate 2, and a positioning component is arranged on the upper side of the hinge frame 17. A support plate 20 is fixedly connected to the left end of the base 1. In this structure, the laser displacement sensor 4 is an existing mature technology, and the data of the material is detected by laser and displayed, so as to observe the presence or absence of the material according to the data display;
[0024] Further, fixing grooves 6 are respectively opened in the middle of the fixing plates 5, and the rollers 10 are connected to the front side of the inside of the fixing grooves 6 through a rotating shaft. First clamping grooves 7 are respectively opened in the upper and lower parts of the inside of the fixing plates 5, and a first spring 8 is arranged in the middle of the inner wall of the first clamping grooves 7. The end of the first spring 8 abuts against a telescopic rod 9, and the telescopic rod 9 is connected to the rotating shaft of the roller 10. This structure can roll the front and rear ends of the PCB board 3 placed on the placement plate 2 and clamp and stabilize it partially through the first spring 8.
[0025] Further, a chute 11 is opened on the left side inside the placement plate 2, and a screw rod 12 is connected to the middle of the inner wall of the chute 11 through a bearing. A torsion block 13 is fixedly connected to the front end of the screw rod 12. A nut 14 is threadedly connected to the surface of the screw rod 12. The surface of the torsion block 13 is arc-shaped. This structure can make the screw rod 12 and the nut 14 perform threaded movement by rotating the torsion block 13, so that the nut 14 moves horizontally on the inner wall of the chute 11.
[0026] Further, the positioning component includes a first positioning rod 16. A fixed shaft 15 is fixedly connected to the left end of the placement plate 2. The upper end of the fixed shaft 15 is fixedly connected to the first positioning rod 16. A movable shaft 18 is arranged at the left end of the placement plate 2, and the right end of the movable shaft 18 is fixedly connected to the surface of the screw sleeve 14. The right sides of the fixed shaft 15 and the movable shaft 18 are adapted to the middle hinge points of the hinge frame 17. The upper end of the movable shaft 18 is fixedly connected to a second positioning rod 19. Through the hinge use of the hinge frame 17, this structure enables each movable shaft 18 to be in the same position during movement, and the distance between them is the same as the distance between the first positioning rod 16 and the second positioning rod 19. Thus, the laser of the laser displacement sensor 4 is adapted to the first positioning rod 16, and each time the placement plate 2 moves, the laser of the laser displacement sensor 4 can be adapted to the holes, eliminating the need for subsequent aiming.
[0027] Further, a second card slot 21 is opened in the upper side inside the support plate 20, and a second spring 22 is arranged in the middle of the inner wall of the second card slot 21. The end of the second spring 22 abuts against a limiting block 23, and the right end surface of the limiting block 23 is spherical. A limiting groove 24 adapted to the right end of the limiting block 23 is opened at the left end of the movable shaft 18. This structure can, when the placement plate 2 moves, through the adaptation of the limiting block 23 and the limiting groove 24, make the placement plate 2 pause partially when it moves to the position of each limiting groove 24.
[0028] Further, a fixed block is arranged on the right side of the base 1, and the fixed block is in contact with the right end of the placement plate 2. A pull handle is arranged at the rear end of the placement plate 2, and the entire placement plate 2 can move backward from the upper end of the base 1. When this structure is in use, through the use of the pull handle, the placement plate 2 drives the PCB board 3 to move backward, thereby enabling rapid detection of each group of holes.
[0029] Further, the right end of the first positioning rod 16 is adapted to the first group of holes on the rear side of the PCB board 3, and both the first positioning rod 16 and the laser of the laser displacement sensor 4 are at the same horizontal level. The right end of the second positioning rod 19 is adapted to the second group of holes on the PCB board 3. This structure enables the laser displacement sensor 4 to work in the horizontal alignment direction.
[0030] Further, the surface of the roller 10 is adapted to the surface of the PCB board 3, and the surface material of the roller 10 is set as rubber. This structure makes it more convenient for the roller 10 to roll when used with the PCB board 3 and avoids the possibility of damaging the surface of the PCB board 3.
[0031] Working principle: When in use, the PCB board 3 is placed in from the right side of the placement board 2. When passing through the surface of the roller 10, the PCB board 3 is partially guided and moves to the left side of the placement board 2. After moving to the middle position of the placement board 2, the PCB board 3 can be stably placed on the upper end of the placement board 2 by the compression and resilience of the first spring 8. At this time, both the first positioning rod 16 and the laser of the laser displacement sensor 4 are adapted to the first set of holes on the PCB board 3, and the use position of the second positioning rod 19 can be adjusted according to the second set of holes on the PCB board 3. By turning the torsion block 13, it drives the screw rod 12, so that the screw rod 12 performs a threaded movement with the nut sleeve 14. At this time, the nut sleeve 14 will move on the inner wall of the chute 11, and then drive the movable shaft 18 on the surface to move, so that the movable shaft 18 drives the second positioning rod 19 to move. After the second positioning rod 19 is adapted to the second set of holes, the rotation can be stopped. At this time, the distance between the fixed shaft 15 and the movable shaft 18, after being adapted by the hinge frame 17, makes the distance between each group of front-side movable shafts 18 equal to the distance between the fixed shaft 15 and the rear-side movable shaft 18. At this time, the laser displacement sensor 4 can be used for detection. By pulling the pull handle backward, the placement board 2 moves on the upper end of the base 1. During the movement, the limiting block 23 will be adapted to the inner wall of the limiting groove 24, and at the same time, the limiting block 23 will squeeze the second spring 22 in the second card slot 21, and after being compressed, it will generate a resilience force to push out the limiting block 23, making it adapted to the limiting groove 24. Thus, during the overall use, after the limiting block 23 is adapted to the limiting groove 24, it will cause a stagnation. At this time, the laser displacement sensor 4 can continue to detect. As the placement board 2 moves and stagnates, each hole can be detected. And the overall use operation is simple. After adjustment, only by pulling can the detection be completed, which is fast and convenient. The above is the entire working principle of the present utility model.
[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes within the meaning and scope of the equivalent elements of the claims in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
