Coil winding machine

Abstract

The invention discloses a coil winding machine. The coil winding machine comprises a winding machine main body; the winding machine main body comprises a machine frame, a winding jig and a bending andpositioning mechanism; the winding jig comprises a front mold and a winding core; the front mold surface of the front mold is provided with a coil containing groove, an outer ring needle hole and aninner ring needle hole; and the bending and positioning mechanism comprises an outer ring bending needle, an inner ring bending needle and a bending needle telescopic driving device. The inner ring bending needle and the coil containing groove are used for positioning the position where pins of inner rings of coils are bent and shaped; the position where pins of outer rings of the coils are bent is positioned by adopting the outer ring bending needle; and the consistency of the formed coils is good. Furthermore, a coil feeding mechanism, a coil grabbing mechanical arm, a jig rotating driving mechanism and a coil shearing mechanical arm are matched to complete coil winding, so that the production efficiency is high, and waste coils cannot be generated. Moreover, a coil stripping mechanism and a coil conveying line are adopted to complete the discharging of the finished coils, so that the automation degree is high.

Description

technical field [0001] The invention relates to manufacturing equipment of electronic components, especially a coil winding machine. Background technique [0002] An existing coil is a hollow ring-shaped flat coil wound from a coil wire, which can be used to manufacture a wireless charger. In existing coil winding machines, the pins of the wound coils can only protrude naturally tangentially, such as figure 1 shown. The follow-up process needs to bend the pins of the coil, and the pins point to the direction from the inner ring to the outer ring, such as figure 2 shown. If manual positioning is adopted, the difference in the operation level of the workers will lead to differences in the positioning of the pin bending position and the difference in the forming effect, and the coil consistency will be poor, which will affect the subsequent process. Contents of the invention [0003] The purpose of the present invention is to solve at least one of the technical problems ...
