[0002] In the modern electronic manufacturing industry, the quality control of circuit board is the key link to ensure the stability of product performance, and aperture detection as an important part directly affects the smooth progress of subsequent assembly process. The traditional manual detection method is not only inefficient, but also prone to inaccurate detection results due to human factors, especially when facing mass production tasks with high precision requirements, its limitations are more obvious; at the same time, although the existing part of automatic detection equipment can improve the detection efficiency, there are still deficiencies in multi-hole simultaneous detection and unqualified hole site alarm, which often needs additional steps to locate the problem hole site, increasing the operation complexity and time cost. Therefore, we propose a circuit board aperture detection device. SUMMARY

[0006] The detection mechanism comprises a sliding sleeve, the sliding sleeve is slidably sleeved on the sliding table, a transmission block is fixedly connected to the upper end of the sliding sleeve, the transmission block is sleeved on and threadedly connected with the lead screw, a motorized telescopic rod is fixedly installed at the middle part of the lower end of the sliding sleeve, a detection frame is fixedly connected to the lower end of the motorized telescopic rod, and multiple detection assemblies are arranged in an array in the detection frame.

[0007] Preferably, the detection assembly comprises a needle gauge and an indicator light, the needle gauge is movably connected with the lower part of the detection frame, a anti-dropping block is fixedly installed at the upper end of the needle gauge, a spring is fixedly connected to the lower end of the anti-dropping block, the spring is sleeved outside the needle gauge, the lower end of the spring is fixedly connected with the lower inner wall of the detection frame, and the indicator light is fixedly installed at the upper end of the detection frame and located directly above the needle gauge.

[0008] By adopting the above technical scheme: the design of multiple groups of detection components significantly improves the detection efficiency, greatly shortens the overall detection time compared with the traditional single-point detection mode, and is particularly suitable for quality control scenarios of mass production.

[0009] Preferably, the lower end of the indicator lamp penetrates the upper part of the detection frame and extends into the detection frame, and the lower end of the indicator lamp is fixedly connected with a static contact point, and the upper end of the anti-dropping block is fixedly connected with a dynamic contact point corresponding to the position of the static contact point.

[0010] By adopting the above technical scheme: during the detection process, if a certain aperture does not meet the standard or the aperture position deviates, the gauge cannot be completely inserted, the anti-dropping block will move up and push the dynamic contact point to contact the static contact point, thereby lighting up the corresponding indicator lamp, so that the operator can quickly locate the problem aperture, avoid unqualified products flowing into the next process, and effectively improve the production quality and efficiency.

[0011] Preferably, the positioning member includes a U-shaped positioning frame fixedly installed at the upper end of the operation table, and the left and right inner walls of the U-shaped positioning frame are fixedly welded with supporting plates, and the upper end of the two supporting plates is placed with a circuit board body, and the circuit board body is attached to the inner wall of the U-shaped positioning frame.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. By arraying multiple sets of detection components within the detection frame, multiple apertures on the circuit board can be detected simultaneously. This design significantly improves detection efficiency and drastically shortens the overall detection time compared to traditional single-point detection methods, making it particularly suitable for quality control scenarios in mass production. Furthermore, during the detection process, if an aperture does not meet the standard or its position is offset, the gauge pin cannot be fully inserted. The anti-disengagement block moves upward, pushing the moving contact to contact the stationary contact, thereby illuminating the corresponding indicator light. This allows operators to quickly locate the problematic aperture, preventing defective products from flowing into the next process and effectively improving production quality and efficiency.

[0018] 2. The design of the positioning components fully considers the fixation and ease of operation of the circuit board. The combination of the U-shaped positioning frame and the support plate provides stable support for the circuit board and ensures its relative position with the testing mechanism, thereby avoiding inaccurate test results due to circuit board misalignment. The use of the baffle and nut further enhances the positioning accuracy. Operators can quickly fix the circuit board by adjusting the position of the baffle and tightening the nut, while also ensuring ease of removal. After testing, the circuit board can be easily removed simply by loosening the nut, eliminating the need for complicated disassembly and assembly steps, greatly simplifying the operation process and improving work efficiency.

[0031] Through the above scheme: a plurality of groups of detection assemblies 85 are arranged in the detection frame 84, which can simultaneously detect a plurality of apertures on the circuit board, which significantly improves the detection efficiency, greatly shortens the overall detection time compared with the traditional single-point detection method, and is particularly suitable for quality control scenes in mass production.

[0032] In the embodiment, the positioning member 2 comprises a U-shaped positioning frame 21 which is fixedly installed on the upper end of the operation table 1, the left and right inner walls of the U-shaped positioning frame 21 are fixedly welded with supporting plates 22, the upper ends of the two supporting plates 22 are placed with a circuit board body, and the circuit board body is attached to the inner walls of the U-shaped positioning frame 21; the front ends of the two supporting plates 22 are fixedly connected with support rods 23, the support rods 23 are slidingly connected with baffles 24, the front parts of the support rods 23 are threadedly connected with nuts 25, and the nuts 25 are located at the front ends of the baffles 24; the baffles 24 are provided with front and rear through guide grooves 26, and the baffles 24 are slidingly connected with the support rods 23 through the guide grooves 26.
