Description

Technical Field

[0001] The invention belongs to the technical field of milling cutter processing and relates to a cutting device for recycling a PCB milling cutter. Background Art

[0002] PCB milling cutter, also called gong cutter, is used in the post-process of PCB (or pressing and catching the outer frame). The main purpose is to use this cutter to cut the finished circuit board into individual PCS or SPNL and then ship it to the customer. That is, the product size required by the customer in the end. This cutter is mainly used for cutting. The blade and force direction are horizontal, similar to the drill needle, but the force and cutting direction of the drill needle are at the drill tip. There are two types of milling cutters: fishtail type and drill tip type. The special design focuses on the service life of the milling cutter and the chip removal effect. Its characteristics are large chip removal grooves, which make chip removal smooth when drilling, low heat generation, and less stains on the hole wall.

[0003] After a period of use, the performance of the PCB milling cutter will decline and cannot meet the production needs, which will lead to the scrapping of the PCB milling cutter. Since the raw materials for the production of PCB milling cutters are expensive, the waste PCB milling cutters can be recycled and reused. The scrapped PCB milling cutter is generally damaged in the blade, but the handle is still intact. At this time, the blade can be cut off and re-welded on the handle. After processing, it can be used normally. However, the existing cutting equipment cannot reciprocate to fix the milling cutter in the process of cutting the scrapped PCB milling cutter. After cutting, the milling cutter needs to be removed again, resulting in cumbersome cutting steps and reducing the efficiency of PCB milling cutter recycling and cutting. Therefore, we propose a cutting device for PCB milling cutter recycling. Summary of the invention
