At the same time, the lower end of the guide rod is fixed to the pressure foot platform 1251 by screws, so that the guide rod can drive the pressure foot assembly 125 and the spindle body 121 to move vertically at the same time, while the pressure block 124 remains still. During this period, the drilling machine control unit monitors the usage data of the drill needle during the operation of the drill head 10, updates it in the display control unit, and transmits the real-time updated usage data to the management unit, and then the management unit writes the drill needle chip through the drill needle reader. For example, the drill needle reader can be installed on the outer wall of the pressure block 124, such as Figure 4 The annular structure in the middle and lower part can be surrounded and sleeved on the main shaft body 121 to keep the drill needle reader relatively still when the drill head is drilling, thereby increasing the stability of the radio frequency signal transmission between the drill needle reader and the chip.

[0077] It should be noted that the drill needle reader body includes an antenna, a radio frequency module and an interface module, and the radio frequency field range and strength thereof can ensure effective communication with the semiconductor element.

[0078] In the several embodiments provided in the present application, it should be understood that the disclosed systems, modules and methods can be implemented in other ways. For example, the module embodiments described above are only schematic, for example, the division of units is only a logical function division, and there may be other division methods in actual implementation, such as multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be an indirect coupling or communication connection through some interfaces, modules or units, which can be electrical, mechanical or other forms.

[0079] The above embodiments are only used to illustrate the technical solution of the present application, but not to limit it. The present application is not limited to the exact structure described above and illustrated in the accompanying drawings, and it cannot be determined that the specific implementation of the present application is limited to these descriptions.
