Modular inline micro-drilling re-grinding device

Abstract

The present invention relates to a modular inline micro drill regrinding device, and more particularly to the use of a washing module after cleaning micro drill used to remove impurities and its pressurized, fixed and re-grinding, through the collar installation module so that binds to the outer peripheral surface of a micro drill collar can automatically adjust its position according to the length of the micro drill after regrinding modular inline micro drill regrinding devices. The present invention is a modular inline micro drill comprises a carrier to be throwaway throwaway micro drill tray; conveyance for conveying the tray portion; rotating portion fixed to be milled and the throwaway micro drill predetermined rotation angle; for heavy grinding throwaway be fixed to any one of micro drill grinding portion; applying pressure from the side facing the micro drill and a fixed blade, thereby preventing the generation of poor quality due to jitter grinding micro drill by regrinding is performed when the abrasive portion holding portion.

Description

technical field [0001] The invention relates to a modular inline micro-drill regrinding device, in particular to a cleaning module that uses a cleaning module to clean the used micro-drill and remove impurities, then pressurize, fix and regrind it, and at the same time install the module through a collar The utility model relates to a modular inline micro-drill regrinding device which enables the collar combined with the outer peripheral surface of the micro-drill to automatically adjust its position according to the length of the reground micro-drill. Background technique [0002] Usually, the processing of PCB (printed circuit board) substrate hole and its appearance is in microns, and its accuracy is very high. In order to meet this requirement, it is necessary to use tools such as small-diameter micro drills, end mill drills, and groove drills. Among them, the diameter of the micro-drill usually used to process the hole of the circuit substrate for mounting the chip is ...

AI Technical Summary

Problems solved by technology

[0003] When using the above-mentioned micro-drill to repeatedly perform hole processing operations, due to friction and heat, it is easy to wear and tear. Therefore, frequent replacement is required, and impurities are prone to be caught on the cutting edge, such as figure 1 (P1) shown

[0004] Due to the above reasons, the staff often need to clean the micro-drill first, and then grind it, which not only increases labor costs, but also reduces production efficiency

[0005] Previously, most of the figure 1 The worn and damaged micro-drills shown in P2 are all discarded. This not only causes waste of high-priced micro-drills and increases the cost of parts, but also leads to an increase in the supply price of circuit boards, which affects the improvement of price competitiveness.

[0006] In order to make up for the above deficiencies, a device and method for using a grinding device to regrind a micro-drill have been developed. However, the slight vibration generated when grinding a micro-drill is also sufficient to reduce the grinding quality of a small-diameter micro-drill. There are more products

[0007] Moreover, the existing regrinding device needs to remove impurities generated at the cutting end of the micro-drill during the process of testing the quality of the regrinded product, and the abrasive cleaning pad used for removing impurities is only rotated, so the scrap rate is extremely high , resulting in a waste of resources

[0008] like figure 1 As shown in P3, the micro drill adjusts the height of the perforation by installing the collar 200. When regrinding the micro drill, it is necessary to adjust the sleeve according to the change in the length of the micro drill protruding from one side of the collar 200 to the direction of the cutting edge. However, it is difficult for the operator to adjust the position of the collar by hand because the length change that occurs during grinding is very small
