The circuit board is an important electronic component, is a support for electronic components, and is a carrier for electrical connection of the electronic components. In the circuit board manufacturing process, the positioning pins 11 are first perforated and inserted into the circuit board 10, as shown in fig. 1, so that the positioning pins 11 play a role in positioning and fixing in the subsequent manufacturing process of the circuit board 10. Thus, in the manufacturing process of drilling the circuit board 10, the circuit board 10 is placed on the table of the circuit board drilling apparatus, which is provided with the clamping position, so that the positioning pins 11 on the circuit board 10 are clamped by the clamping position on the table to define the circuit board 10 to be supported on the table, and the movement control mechanism of the circuit board drilling apparatus controls the drill to drill the circuit board 10 defined to be supported on the table.

In order to make the machining coordinate system of the drilling spindle of the circuit board drilling apparatus coincide with the clamping position coordinate system of the positioning pins 11 of the circuit board clamped on the table, it is necessary to detect the clamping position on the table. However, in the existing detection mode, a standard pin is placed in a clamping position on a workbench, a first end of the standard pin is clamped by the clamping position on the workbench, and a second end of the clamping detection standard pin is detected manually through a dial indicator to obtain coaxiality between the standard pin and a drilling spindle of the circuit board drilling equipment, so that drilling deviation data of the clamping position on the workbench and the drilling spindle of the circuit board drilling equipment are obtained, and then the position of the clamping position on the workbench is adjusted pneumatically, however, the manual detection efficiency is low, and the precision is poor; the other detection mode is that a standard pin is placed in a clamping position on a workbench, the first end of the standard pin is clamped by the clamping position on the workbench, a drilling spindle of the circuit board drilling device drives a cutter to touch the left position, the right position, the upper position and the lower position of the second end of the standard pin, so that a detection mechanism can detect coordinates of the left position, the right position, the upper position and the lower position of the second end of the standard pin, however, the detection mode needs to carry out touch detection on the four positions of the left position, the right position, the upper position and the lower position of the second end of the standard pin, the touch detection positions are too many, the detection efficiency is affected, the force of the touch detection is difficult to control, and the too large touch force can cause the second end of the standard pin to deviate, and the detection precision is affected.
