Description

technical field [0001] The invention relates to a pin bending device of electronic components, in particular to an induction coil pin bending machine. Background technique [0002] With the development of electronic technology, SMT surface mount or surface mount technology has been widely used. In order to mount non-pin or short-lead surface mount components on the surface of printed circuit boards or other substrates, surface mount components are required. For example, inductance coils need to bend their pins before welding. In the prior art, in most cases, workers use small needle-nose pliers to manually bend. To complete the pre-soldering pin bending of 2000 circuit boards. As the number of labors increases, workers become more fatigued and work efficiency decreases; in addition, the bending length and angle are controlled by the operators themselves, which will result in inconsistent product quality, high damage rate of inductance coils, and lower product qualification ...

AI Technical Summary

Problems solved by technology

As the number of labor increases, the workers become more fatigued and the work efficiency decreases; in addition, the bending length and angle are controlled by the operators themselves, which will result in inconsistent product quality, high damage rate of the inductance coil, and reduce the qualified rate of the product

For example, the bends of the two legs are inconsistent and flat, and cannot be bonded to the surface of the printed circuit board. Too much bending will cause a local short circuit on the circuit board after welding, and too little bending will cause virtual soldering.

[0003] In the prior art, there is also a mechanized inductance coil pin bending device, including an inductance coil positioning mold, a limit pressing block, an upper bending punch, a foot cutting punch and a side bending punch; Every time the bending device bends an inductance coil, it needs to be manually removed from the positioning mold to pick up the parts, and the work efficiency is still not high.

Improper force to remove the mold and pick up the parts may cause the inductance coil to be bent, deformed and scrapped, and the pass rate of the product is still low

[0004] There is also a similar technical solution. On June 05, 2013, the Chinese utility model authorization announcement number CN 202963310 U disclosed a bending device for inductive wire pins, including a start button 1, a bending socket, an indicator light, and a start button 2. , protective cover, circuit board positioning hole, circuit board placement jig, electric control system, biaxial push cylinder 1, inductive wire straightening cylinder, biaxial push cylinder 2, inclined slider and pressure wheel, said circuit board placement jig There is an inductance wire straightening cylinder on the top. Although this device can realize the bending of the inductance wire pins, the inductance wire pins are inserted into the circuit board for bending. After each bending, the position of the circuit board needs to be adjusted. Reasons and other issues, its size is difficult to ensure consistency, and the yield rate is also low
