Description

Technical Field

[0001] The utility model relates to the technical field of circuit board detection, in particular to a detection and alignment device for laminated circuit boards. Background Technique

[0002] Circuit board detection is to ensure the production quality of circuit boards and improve the qualification rate of products. The main detection methods can be divided into two categories: electrical testing methods and visual testing methods. Visual inspection: This method is mainly applicable to the appearance inspection of circuit boards and is not applicable to the detection of internal layers of circuit boards. If there are no obvious visible defects on the appearance, it is necessary to power on the circuit board and perform more detailed tests to detect whether the circuit board is normal.

[0003] In the utility model patent with the patent publication number CN219319358U, by setting a fixing component, under the limiting action of the positioning seat on the positioning ring, the control rod can be rotated and limitedly rotated inside the through groove. And under the meshing connection between the control rod and the clamping block, due to the opposite thread directions on the surfaces of both ends of the control rod, the two clamping blocks can move towards each other to complete the clamping and positioning of the circuit board from both sides, and the limiting plate can be firmly placed on the surface of the alignment plate to avoid moving and affecting the detection. Although this method can complete the alignment work, it can only detect a single circuit board at the same time, reducing the overall detection effect and being not conducive to practical use.

[0004] Therefore, it is necessary to provide a detection and alignment device for laminated circuit boards to solve the above technical problems. Content of the Utility Model
