Thread end blowing-straightening device of micro motor coils

Abstract

Provided is a thread end blowing-straightening device of micro motor coils. The thread end blowing-straightening device comprises a clamp used for clamping the coils, and a high pressure gas conveying device. The clamp is composed of a base and a clamping mechanism. A plurality of blow holes distributed in a queue mode are arranged in the top face of the base and are communicated with a cavity arranged in the bottom face of the base. The clamping mechanism is composed of a locating support and a mobile support. The locating support is arranged at the upper ends of the blow holes, the mobile support is matched with a limiting chute in the base in a sliding mode, a plurality of locating cross bars on the mobile support are staggered with the locating support, and a device used for controlling motion of the mobile support is assembled between the mobile support and the base. A locating groove is arranged in a working platform of the high pressure gas conveying device, and ventilation holes are arranged in the bottom of the locating groove and are communicated with a solenoid valve controlling gas conveying. The thread end blowing-straightening device can clamp a plurality of the coils at a time, high pressure gas is adopted for automatically blowing the thread ends on the coils to be straight, the thread ends can not be damaged, production efficiency and a product qualified rate are improved greatly, visual fatigue of workers can be avoided, and labor intensity of the workers is reduced greatly.

Description

technical field [0001] The invention relates to the field of motor coil processing, in particular to a wire end blowing device for micro motor coils. Background technique [0002] The coil of the micro motor is very small, and the diameter of the copper wire of the coil winding is generally about 0.06mm. After the coil is wound, there is a wire end with a length of more than 1.5mm, and it is necessary to coat the wire end with solder so that the wire end of the coil is welded with the circuit. Easy to weld firmly. Due to the small volume of this type of coil and the thin copper wire, after the coil is wound, the wire end presents a chaotic and irregular bending state, which makes it difficult to apply solder on the wire end. For a long time, to apply solder on the wire ends of micro motor coils, usually firstly straighten the wire ends one by one with tweezers manually, and then insert the straightened wire ends into the melted tin liquid, so that the wire ends are coated w...

Problems solved by technology

However, this method of straightening the straight ends requires a lot of labor and takes a lot of time, and the production efficiency is extremely low; and it is extremely easy to scratch the paint layer on the coil during the manual use of tweezers to straighten the straight ends, and it is also easy to tear the thread ends Broken, which leads to the scrapping of the coil, which brings losses to the enterprise; at the same time, because the workers stare at such a small thread for a long time, it will cause visual fatigue and increase the labor intensity. affect the production of the enterprise
