Description

Technical Field

[0001] The utility model relates to the technical field of drilling depth detection, in particular to a PCB controlled depth drilling depth detection device. Background Art

[0002] With the development of the industry, customers have put forward higher requirements for PCB drilling. For example, in the production process of mechanical blind holes, countersunk holes, and back drilling holes, depth-controlled drilling technology will be used. There is currently no equipment in the industry that can directly detect the depth of the holes processed by depth-controlled drilling. It can only be measured using a needle gauge with a scale or a slice.

[0003] After searching, the patent number is CN217877487U, which discloses a PCB controlled depth drilling depth detection device. Although the utility model is connected to a drill bit at the end of the probe, the drill bit is driven to move by the screwing in and out of the probe, so that the drill bit can perform the measurement point detection operation. Among them, the linkage between the probe and the drill bit does not consume an additional driving mechanism, which is simple and effective; the probe and the drill bit are connected by a probe ring, and the pluggable setting between the probe ring and the drill bit can connect drill bits of different diameters, so as to measure controlled depth holes of different specifications. However, when in use, when there are multiple drill holes on the PCB board, the detection personnel need to manually adjust the position of the PCB board so that the drill holes are aligned with the probe for measurement, which requires a lot of time and energy of the detection personnel, affecting the detection effect. At the same time, the detection personnel need to read the readings when measuring through the probe, and the detection results are prone to large errors, further affecting the detection effect.

[0004] Therefore, a PCB controlled depth drilling depth detection device is proposed. Utility Model Content
