Automatic wire end blow-straight device of micro motor coil

Abstract

The invention relates to an automatic wire end blow-straight device of a micro motor coil; a motor of a conveying device is arranged on one side of a frame; a first conveyer belt and a second conveyer belt with a slot are arranged in the frame in parallel; the motor, the first conveyer belt and the second conveyer belt are connected through a belt; a limit device is fixedly arranged on a working platform of the frame; a support of the limit device is fixedly arranged on the upper end surface of the working platform; a limit block is fixedly arranged on the support through a cross bar and is suspended; space for a clamp which is used for clamping the coil to pass through is left between the bottom of the limit block and the upper end surface of the working platform; a blowing device is arranged below the working platform; the upper end surface of the working platform is provided with a guide chute; the bottom of the guide chute is provided with a vent hole which is communicated with an electromagnetic valve; and an electromagnetic switch is arranged closely to the vent hole. According to the automatic wire end blow-straight device of the micro motor coil, the clamp which clamps the coil can be automatically conveyed to the blowing device, the wire end on the coil is automatically blown straight by high-pressure air, so that automatic production is realized, the production efficiency and product qualified rate are improved, and the labor intensity of a worker is reduced.

Description

technical field [0001] The invention relates to the field of coil processing of motors, in particular to an automatic thread straightening 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 0.03mm. 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 wir...

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
