Full-automatic quality detection device of micro drill point for drilling PCB

Abstract

The invention relates to a full-automatic quality detection device of a micro drill point for drilling a PCB in the technical field of tool detection, which comprises a feeding mechanism, a rotary worktable, a micro drill rotary mechanism, a height adjusting mechanism, a vision detection device and a discharging mechanism, wherein the feeding mechanism, the rotary worktable and the discharging mechanism are respectively and correspondingly arranged at a feeding station, a rotary station and a discharging station of a working platform, the micro drill rotary mechanism and the height adjusting mechanism are sequentially arranged at the side face of the rotary table, the vision detection device is arranged at a vision detection station of the working platform, the feeding station and the rotary station are arranged at the same side, the discharging station and the feeding station are positioned at two ends of the working platform, and the vision detection station and the discharging station are positioned at the same side. The micro drill rotary mechanism and the height adjusting mechanism can enable a micro drill to simultaneously realize the circumferential rotation and the axial real-time precise adjustment, can fine adjust the axial positioning height of the micro drill in real time, and ensure the imaging quality of a blade surface and the measurement precision of geometric parameters.

Description

technical field [0001] The invention relates to a device in the technical field of tool detection, in particular to a fully automatic quality detection device for a miniature drill for PCB board drilling. Background technique [0002] For the detection of the quality of micro-drills, the traditional methods mostly rely on human eyes to observe the measurement results to judge whether the micro-drills are qualified. These detection methods are labor-intensive, and the detection personnel are prone to misjudgment due to fatigue, and are highly dependent on experience. [0003] After searching the literature of the prior art, it is found that the Chinese patent document number CN2559963Y records a "special micro-drill inspection device for PCB board drilling", which uses a microscopic device and its adjustment mechanism to enlarge the image of the micro-drill and display it on the display. , the user completes the inspection based on the micro-drill image. For the microscopic...

Problems solved by technology

But the disadvantage is: due to structural reasons, during the inspection process, especially during the automatic feeding and receiving process, the micro-drilling tip is prone to breakage or shock, and the stability needs to be improved; secondly, the device does not use automatic feeding When the device is installed, the side and edge surface of the micro-drill can be detected at the same time, but the detection efficiency is low, and the micro-drill still needs to be replaced by manual operation; after the device is equipped with an automatic feeding device, although the degree of automation is further improved, only the edge of the micro-drill is Surface detection, the two cannot be taken into account

In addition, the device has a weak sorting function for the quality of micro-drills, and further sorting is required manually
