[0028] During operation, the frame 1 is also provided with a manipulator (not shown), which is used to pick up the PCB milling cutter to be inspected and place it in the cleaning component 8 for blowing and cleaning the tungsten powder and cutting fluid adhered to the PCB milling cutter, so as to effectively remove the dirt of the PCB milling cutter to be inspected, and avoid misjudgment caused by dirt during inspection. Then, the cleaned PCB milling cutter is installed on the clamping table 3, and the clamping table 3 is driven by the driving member 4 to move up and down along the Z-axis direction and rotate around the Z-axis. The diameter, concentricity, taper, etc. of the PCB milling cutter are automatically inspected by the laser detector 5. After the inspection work of the laser detector 5 is completed, the PCB milling cutter is sent to the radial inspection component 6, and the radial inspection component 6 is used to automatically inspect the full length, right helix angle, left helix angle, left-handed tooth width, groove bottom width, fishtail angle, diameter taper and other dimensions of the PCB milling cutter. At the same time, the axial detection component 7 is used to automatically detect the right-hand core thickness, left-hand core thickness, fishtail clearance and other dimensions of the end teeth of the PCB milling cutter, as well as the appearance gap of the fishtail. The PCB milling cutter after the detection is sent back to the designated placement to avoid mixing, thereby completing the full-size automatic detection of the PCB milling cutter. Finally, the actual data detected is automatically compared with the standard data, the deviation is automatically analyzed and automatically uploaded to the central control system, and the central control system automatically makes a decision based on the deviation: 1. For data that can be corrected by coordinate compensation, the central control system issues an instruction to the PCB milling cutter production equipment to automatically compensate for the processing data and correct the deviation; 2. For data that cannot be compensated by program software, the central control system issues an instruction to the PCB milling cutter production equipment to alarm or shut down, and sends information to the adjustment personnel. After the hardware is manually adjusted to meet the standard requirements, the production equipment is restarted. Among them, the full-size detection items of the PCB milling cutter include diameter, full length, right helix angle, left helix angle, left-handed tooth width, groove bottom width, left-handed overlap, left-handed grinding wheel deformation, right-handed grinding wheel deformation, right-handed core thickness, left-handed core thickness, fishtail clearance, fishtail angle, blade taper, appearance such as blade band and fishtail gap, etc. The full-process automated detection operation greatly reduces the labor intensity of manual detection and improves detection efficiency and detection accuracy. Therefore, the present application realizes automatic detection of PCB milling cutter parameters and automatic compensation and correction of deviations according to the parameters, and has the advantages of high efficiency, high accuracy, low production cost, and wide applicable range. Through automatic full-size sampling and uploading of data, the labor intensity of manual labor is greatly reduced, the efficiency and accuracy of detection are improved, and the feedback speed of responding to deviations is improved, so that the production process becomes controllable, reliable, and efficient, and the yield rate of the products produced is also greatly improved. The utility model realizes automatic detection of various parameters of the full size of the PCB milling cutter and processes and analyzes and compensates for deviations according to various parameters, saving labor costs, simple and convenient operation, and improving detection accuracy and detection efficiency.
