Description

TECHNICAL FIELD

[0001] The utility model relates to electronic component processing equipment technical field, especially an inductance winding fixture. BACKGROUND

[0002] In the inductance manufacturing process, the winding quality of inductance coil directly affects the performance and reliability of inductance. In the prior art, a special fixing jig is not usually used in the inductance winding process, which causes the inductance magnetic core to be prone to displacement during the winding process. Due to the lack of fixing device, the operator cannot ensure the uniform tension of the wire during winding, resulting in inconsistent tightness of the wire. In this case, the wire length of the finished inductance product has differences, and the inductance consistency is poor, which seriously affects the product quality stability. At the same time, due to the unstable winding quality, the product rework rate is high, which increases the production cost. The conventional clamp has a small contact area with the inductance magnetic core, and the fixing effect is not ideal, which causes the magnetic core to shake during the winding process, affecting the winding precision. These problems cause the appearance consistency of inductance products to be poor, the performance to be unstable, and the production efficiency to be low. SUMMARY
