The PCB circuit board is not only a support for electronic components, but also a carrier for the electrical connection of electronic components. With the development of modern technology, PCB circuit boards are used in more and more fields. Before being put into use, PCB circuit boards often need to be detected by a detection device.

[0003] When traditional PCB circuit board detection is carried out using detection equipment, the detection personnel need to manually repeatedly take and adjust the detection position and detection angle of the PCB circuit board to avoid problems on the surface of the circuit board from not being detected due to being blocked by other objects. In such a detection process, the PCB circuit board needs to be removed from the corresponding fixture multiple times, which is time-consuming and laborious, and is extremely likely to cause secondary damage to the PCB circuit board during the repeated clamping and removal process, affecting the accuracy of the detection result of the circuit board. Also, in the prior art, after one side of the PCB board is detected, the PCB board needs to be flipped to detect the other side, and the detection process is complex and the detection efficiency is not high.

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] Embodiment 1

[0026] The PCB board detection device provided in this embodiment is as Figures 1-4 shown. It includes a detection device 27 and a fixed part 12. The PCB board is detachably fixed to the fixed part 12, and the detection device 27 detects the PCB board. The detection device further includes an annular guiding part 2 and a driving part 29. The annular guiding part 2 and the fixed part 12 are fixed on a fixed table 1. The bottom of the fixed table 1 is provided with a hole through which the annular guiding part 2 can pass.

[0027] In this embodiment, a support plate 11 is fixedly arranged at the bottom of the fixed table 1. The other end of the support plate 11 is fixedly connected to the inner side of the annular guiding part 2. The width and thickness of the support plate 11 are sufficient to support the annular guiding part 2.

[0028] The annular guiding part 2 surrounds above the surface of the PCB board to be detected. The detection device 27 is slidably arranged on the annular guiding part 2. The driving part 29 is connected to the detection device 27 and drives the detection device 27 to slide along the circumferential direction of the annular guiding part 2, so that the detection device 27 detects all the surfaces of the PCB board to be detected.

[0029] In this embodiment, the annular guiding part 2 is arranged as a closed circular ring. The driving part 29 drives the detection device 27 to slide forward or backward or back and forth along the circumferential direction of the annular guiding part 2.

[0030] The detection device 27 is arranged on the annular guiding part 2 through a sliding member. A plurality of transmission gear blocks 21 are arranged on the outer surface of the annular guiding part 2. The sliding member can slide along the transmission gear blocks 21.

[0031] Specifically, the sliding member includes a sliding frame 22 and a rotating rod 23 arranged in the sliding frame 22. The sliding frame 22 is slidably sleeved on the outside of the annular guide portion 2. The end of the rotating rod 23 is connected to the driving portion 29. A plurality of transmission gears 24 are arranged on the middle outside of the rotating rod 23. The transmission gears 24 are meshed with the transmission gear block 21. The driving portion 29 drives the rotating rod 23 to rotate, thereby realizing the sliding of the sliding frame 22 on the annular guide portion 2.

[0032] A connecting plate 25 is laterally fixedly installed on the outer bottom surface of the sliding frame 22, and an electric push rod 26 is fixedly connected to the bottom surface of the connecting plate 25. The other end of the electric push rod 26, i.e., the transmission shaft, is fixedly connected to a detection device 27; the distance between the detection device 27 and the PCB board is adjusted by the electric push rod 26.

[0033] The sliding frame 22 is slidably sleeved on the outer side of the annular guide portion 2. The specific structure is that a sliding block 4 is fixedly arranged in the sliding frame 22, and a guide groove 41 is arranged on the outer side of the annular guide portion 2. The sliding block 4 slides in the guide groove 41. Specifically, the sliding block 4 is slidably inserted into the sliding groove. Under the sliding guiding effect of the sliding groove on the sliding block 4, the sliding frame 22 can only move along the outer side of the annular guide portion 2 after being driven, and will not detach from its surface to affect the detection use.

[0034] In actual use, a mounting frame 28 can be fixedly connected to the outer surface of the sliding frame 22, and a driving unit 29, such as a servo motor, is placed inside the mounting frame 28. The transmission shaft of the driving unit 29 is connected to the rotating rod 23 through a coupling, so that the driving unit 29 drives the rotating rod 23 and the sliding frame 22.

[0035] By sliding the sliding frame 22 on the outside of the annular guide part 2, and combining the meshing transmission of the transmission gear 24 and the transmission gear block 21, and synchronously adjusting the detection position of the detection device 27 by the electric push rod 26, the detection device 27 can perform multi-directional and multi-angle detection processing on all the surfaces to be detected of the PCB board to be detected, and there is no need to repeatedly take the PCB board for face replacement and adjust the angle during the detection process, so as to avoid secondary damage to the PCB board and affect the accuracy of the detection result. The problem that the detection device 27 is too far away from the PCB board to be detected and cannot adjust its detection position in multiple directions is completely avoided.

[0036] In order to better fix the PCB board, the structure of the fixing part 12 is improved. In this embodiment, the fixing part 12 is in the shape of a square frame, which includes a pressing plate 31 and an adjusting member 3. The adjusting member 3 is abutted against the side of the pressing plate 31. The adjusting member 3 pushes the pressing plate 31 to move horizontally within the fixing part 12, so as to fix PCB boards of different sizes with the pressing plate 31. The adjusting member 3 can be an adjusting bolt installed through the side of the fixing part 12, with a simple structure and easy operation. By turning the adjusting bolt, the horizontal position of the pressing plate 31 inside the fixing part 12 can be adjusted to ensure that the pressing plate 31 can clamp and fix PCB boards of different sizes.

[0037] Further, at least two guide rods 32 are fixedly connected to the side of the pressing plate 31. The guide rods 32 penetrate through the side of the fixing part 12 and are respectively arranged on both sides of the adjusting member 3. Specifically, two slot holes 33 can be provided on the side of the fixing part 12, and the guide rods 32 pass through the slot holes 33 and are fixedly connected to the pressing plate 31. When the pressing plate 31 moves under the action of the adjusting member 3, it can drive the guide rods 32 to move relative to the side of the fixing part 12. Due to the action of the two guide rods 32, the pressing plate 31 can only move horizontally and will not shift laterally, thereby ensuring the stability of the pressing and fixing of the PCB board.

[0038] Still further, a protective soft pad is fixedly connected to the surface of the pressing plate 31 in contact with the PCB board. Through the protection of the protective soft pad, damage to the side edges of the PCB board caused by the pressing plate 31 can be avoided.

[0039] In this embodiment, the annular guiding part 2 is arranged as a closed circular ring. In order to save costs, the driving part 29 can only drive the detection device 27 to slide forward or backward along the circumferential direction of the annular guiding part 2, so as to detect all the parts to be detected of the PCB board. In this way, the structure of the driving part 29 is relatively simple and the cost is also low.

[0040] During operation, the PCB board to be detected is placed flat in the fixing part 12, and then the adjusting bolt is turned, so that the pressing plate 31 moves laterally inside the fixing part 12 and fits against the side edge of the PCB board, pressing and limiting the PCB board inside the fixing part 12 and fastening it.

[0041] Start the electric push rod 26 to drive the detection device 27 to move vertically, and adjust the distance between the detection port at the bottom of the detection device 27 and the PCB board, so that the bottom position of the detection device 27 will not be blocked by the fixing part 12 during rotation, and at the same time, the bottom of the detection device 27 can detect the PCB board.

[0042] Start the detection device 27; synchronously start the driving part 29 to make it operate, driving the rotating rod 23 and the transmission gear 24 sleeved on its surface to rotate synchronously inside the sliding frame 22. Under the meshing transmission of the transmission gear 24 and the transmission tooth block 21, and combined with the sliding guiding effect of the sliding groove on the sliding block 4, the sliding frame 22 can be driven to rotate along the outside of the annular guiding part 2, so that the sliding frame 22 can drive the electric push rod 26 and the detection device 27 to rotate around the fixing part 12 and the outside of the PCB board placed inside it, so as to quickly detect the PCB board in multiple directions.

[0043] Embodiment 2

[0044] The PCB board detection device provided in this embodiment is as Figure 5 shown. The difference from Embodiment 1 is that the annular guiding part 2 is an unclosed circular ring, and the driving part 29 is a bidirectional motor, driving the detection device 27 to slide back and forth in the circumferential direction of the annular guiding part 2 in the positive and negative directions.

[0045] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
