Description

Technical Field

[0001] The present invention relates to the field of resistor granule folding, and in particular to a granule folding device for manufacturing chip resistors and a method of using the same. Background Art

[0002] Chip resistors are a type of metal glass glaze resistor. They are made by mixing metal powder and glass glaze powder and printing them on a substrate using screen printing. They are resistant to moisture and high temperatures, have a small temperature coefficient, and can greatly save circuit space costs and make the design more refined. Chip resistors are formed into a plate shape after the pre-process preparation process and will be cut by a granulator.

[0003] For example, the Chinese patent publication number CN213935801U proposes a chip resistor folding machine. The chip resistor folding machine is provided with a convertible cutting and folding structure. It is not only easy to disassemble and use, but also easy to adjust a variety of cutting angles, effectively improving the folding efficiency. The height of the connection can be adjusted up and down to prevent a large number of chip resistors from scattering and overflowing, thereby ensuring the folding quality of the chip resistors. However, when folding the chip resistors, the plate-shaped resistors need to be cut into strips first, and after adjusting the angle of the strip resistors, the strip resistors need to be cut again to obtain the folded resistors, resulting in the folding efficiency of the folding machine being too low when folding the resistors. Summary of the Invention
