Technical Field

[0001] The utility model relates to the technical field of chip resistor production, in particular to a chip resistor production strip folding device. Background Art

[0002] Chip resistors, also known as business card-type fixed 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. Chip resistors are in a plate-like shape during the pre-process preparation process, and the resistor plate usually needs to be folded into strips and cut later.

[0003] In this regard, China's patent application announcement number: CN220796383U discloses a strip folding device for chip resistor production, which relates to the technical field of chip resistor production, including a platform, a pair of columns are fixedly arranged on the platform, a beam is fixedly arranged on the pair of columns, a slider is slidably arranged on one side of the beam, a mounting plate is fixedly arranged below one side of the slider, and multiple tool holders are fixedly arranged below the mounting plate. The multiple tool holders are arranged obliquely relative to the moving direction during cutting, and each tool holder is provided with a cutter, and the distance between each cutter is equal. The device can drive multiple rotating cutters through the slider to cut the chip resistor board, thereby realizing the simultaneous cutting of multiple chip resistor strips and improving work efficiency. The cut chip resistor strips can be cut off from the patch resistor board in sequence through the obliquely arranged cutters, preventing multiple patch resistor strips that have not been completely cut from falling off from the patch resistor board at the same time, so as to ensure that multiple patch resistor strips are completely cut.

[0004] However, when actually performing folding strip cutting, the cutting device needs to slide as a whole, but the cutting device also needs to work while moving, so the vibration will cause the cutting position to shift, so the folding strip cutting effect is poor, and the chip resistor strip cannot be limited and transported.
