Description

Technical Field

[0001] The invention belongs to the technical field of steel shank material collection, and relates to an automatic material collection machine dedicated to PCB drill steel shanks. Background Art

[0002] As electronic products are becoming lighter, thinner, shorter and smaller, the size of various electronic products is also gradually shrinking. The manufacturing and processing of various parts inside electronic products are also becoming more and more sophisticated. Generally, printed circuit substrates are indispensable components of electronic products, and the size of printed circuit substrates must be reduced as the size of electronic products is reduced.

[0003] In the manufacturing process of printed circuit boards, cutting tools are essential cutting tools. The PCB steel shank drill bits in the cutting tools are generally made of high-hardness tungsten carbide steel or other hard alloy materials. During the production process of the tool at the printed circuit board, the tool head is easily damaged when it contacts the printed circuit board. If the entire tool is scrapped and replaced with a new tool, resources will be wasted, which will increase the production cost. However, cutting off the tool head and recycling the remaining PCB drill steel shank will make it more economical and environmentally friendly. After grinding, the existing PCB drill steel shanks need to be placed in the corresponding placement box to facilitate subsequent welding and clamping. However, the existing PCB drill steel shank collection is all done manually, which is labor-intensive and has low collection efficiency. Therefore, we propose a special automatic collection machine for PCB drill steel shanks. Summary of the invention
