[0002] After the production of the PCB board, it needs to be detected. By taking pictures of the surface of the PCB board with a high-definition camera and transmitting the images to a computer system for analysis and comparison, it is possible to detect whether there are missing hole positions on the PCB board, whether there is dirt on the PCB board, etc., which are detection items that can be judged by the appearance of the PCB board. For this reason, the utility model proposes a novel rapid detection device for PCB boards. Summary of the Invention

[0003] The purpose of the utility model is to propose a novel rapid detection device for PCB boards to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution. The novel rapid detection device for PCB boards includes a detection table. A number of positioning holes penetrating the upper and lower parts of the detection table are opened on the detection table. A positioning block is detachably installed on the positioning holes. A chute penetrating the positioning block is opened on the positioning block. A support plate is slidably arranged in the chute. A limiting plate is fixedly installed at the top of one end of the support plate. A camera for shooting is installed above the detection table.

[0005] Preferably, a positioning column is fixedly arranged at the bottom of the positioning block. The outer surface of the positioning column is provided with threads and is slidably connected with the positioning hole. A nut is screwed on the positioning column.

[0006] Preferably, a fixing bolt is screwed on the positioning block. One end of the fixing bolt penetrates into the positioning block from the outside of the positioning block and can extend into the chute.

[0007] Preferably, a buffer pad is arranged on one side of the top of the support plate close to the limiting plate.

[0008] Preferably, the end of the limiting plate away from the support plate is in a curved arc shape.

[0009] Compared with the prior art, the beneficial effect of the utility model is that a platform for placing the PCB board is formed by a plurality of support plates, and the position of the PCB board is restricted by the limiting plates on each support plate, so that the position of the PCB board is fixed every time the camera takes pictures for image comparison.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Referring to FIGS. (1-4), a new type of PCB board rapid detection device includes a detection table 1, characterized in that: a plurality of positioning holes 11 penetrating the upper and lower parts of the detection table 1 are provided on the detection table 1, a positioning block 2 is detachably installed on the positioning holes 11, a sliding groove 24 penetrating the positioning block 2 is provided on the positioning block 2, a support plate 3 is slidably arranged in the sliding groove 24, a limiting plate 31 is fixedly installed at one end of the top of the support plate 3, and a camera 4 for shooting is installed above the detection table 1.

[0017] A positioning column 22 is fixedly arranged at the bottom of the positioning block 2, the outer surface of the positioning column 22 is provided with threads and is slidably connected with the positioning hole 11, and a nut 23 is screwed on the positioning column 22. A fixing bolt 21 is screwed on the positioning block 2, and one end of the fixing bolt 21 penetrates into the positioning block 2 from the outside of the positioning block 2 and can extend into the sliding groove 24. A buffer pad 32 is arranged on one side of the top of the support plate 3 close to the limiting plate 31. One end of the limiting plate 31 away from the support plate 3 is in a curved arc shape.

[0018] When the device is in use, insert the positioning post 22 of the positioning block 2 into the positioning hole 11, and tighten the nut 23 to fix the positioning block 2 on the detection table 1. Insert the support plate 3 into the sliding groove 24 of the positioning block 2, and make the limiting plates 31 on each support plate 3 fit against the side of the PCB board. Tighten the fixing bolt 21 so that the fixing bolt 21 presses the support plate 3 in the sliding groove 24 to limit the sliding of the support plate 3 on the sliding groove 24. At this time, place the PCB board on the middle area surrounded by the limiting plates 31 on each support plate 3, control the camera 4 to take pictures of the PCB board, and transmit the captured image data to the computer system for recognition and comparison to detect whether there are any abnormalities in the appearance of the PCB board.
