Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board drilling auxiliary inspection device. Background Art

[0002] A circuit board is a printed circuit board or printed circuit board. Its English name is Printed Circuit Board, also known as PCB or circuit board. Common circuit boards include single-sided boards, double-sided boards, multi-layer boards, flexible boards, rigid-flex boards, etc. Circuit board production involves multiple processes such as cutting, drilling, copper plating, pattern transfer, electroplating, film stripping, and etching. In the process of drilling holes in circuit boards, drilling equipment is generally used to drill holes according to preset hole positions. During the drilling process, the positioning holes may deviate due to positioning or fixture deviations, or the quality of the holes may not meet the requirements due to the winding of the drill cutter, etc. Therefore, after the drilling is completed, in order to ensure the quality of the product, the circuit board with holes needs to be inspected to ensure that the holes in the circuit board can meet the design requirements. Generally speaking, in order to improve efficiency, visual sensors are usually used to collect images of circuit boards for inspection. However, in the actual implementation process, it is difficult to maintain a high degree of consistency in the image effect obtained by the visual sensor. It may be affected by factors such as dust in the working space, the movement of workers, or changes in ambient light caused by the material handling process, which may lead to false detection or missed detection. Therefore, after the visual inspection, manual sampling / full visual inspection is still required to reduce the probability of defects and avoid affecting subsequent product processing. At present, the process of manual visual inspection is generally to collect the circuit boards and transfer them to the table for inspection. After inspection, the circuit boards are sent back to the next process, which requires multiple transfers, which is inefficient and the transfer process is prone to damage the circuit boards.
