Design, and provide a continuous automated process of automatic drilling, calibration, drilling and unloading collection and discharge of good and bad products. [Conventional background] In the process of making PC boards in the office, in addition to printing one or more conductive films to form a circuit layout, it is necessary to drill conductive holes at appropriate positions on the PC board to prepare conductive metal plating. So that the conductive film between the specified PC board levels can be connected to form a conductive circuit, or an electronic component insertion hole is drilled at an appropriate position on the PC board, so that the electronic component can be inserted and soldered to the circuit of the PC board It forms the electronic control circuit on the PC board. However, at the current stage of industrial technology, when drilling PC boards, the number of holes to be drilled on each unit is extremely large, and the depth of the hole is different, so the computer automatically sets them. Equipment for grasping and automatically feeding countersinking (hereinafter referred to as drilling equipment) to perform PC board drilling operations. And in order to help the drilling equipment to effectively control the accuracy of countersinking when picking up the countersink plate, the accuracy of the drill's cutting edge must be controlled to a certain level. 0 The conventional drilling method uses manual labor. The drilling and unloading operations are performed in the manner described above, and the image area of the cutting edge of the cutting edge is observed using a tool microscope, and then the artificial cutting edge is used to detect whether the cutting edge of the bit is good or defective. The general image of the defective cutting edge can be divided into nine categories, as shown in Figure 11a is the image of the inner arc of the drill edge, Figure 11b is the image of the outer arc of the drill edge, and Figure 11 is applicable to Chinese national standards ( CNS) A4 specification (210X2927 mm j (please read the precautions on the back before loading-page)) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 479126 A 7 B7 V.

Although the drilling, unloading and measuring operations are performed manually, the drill edge can be identified. Good and bad products, but because of human error, it is very easy to misidentify the good and bad products of the cutting edge, and thus cannot effectively control the quality of the cutting edge. Therefore, there is a need to strengthen the improvement, and use manual methods to take the drill , Unloading and surveying operations are too wasteful Force resources are not in line with economic benefits. [Brief description of the present invention] The main purpose of the present invention is to detect the precision of the cutting edge of the special drill for PC board drilling, and to provide automatic drilling, calibration, test drilling, and good quality.
