Automobile solenoid valve coil winding process

Abstract

The invention provides an automobile solenoid valve coil winding process. According to the process, a PLC control system and a winding displacement guide pin, a winding displacement sensor, a winding mechanism, a wire hooking mechanism, a striping mechanism and a fixed wire clamping tool which are connected with the PLC control system and a follow-up wire clamping tool connected with the winding mechanism are included. The winding displacement guide pin, the winding displacement sensor, the winding mechanism, the wire hooking mechanism, the fixed wire clamping tool and the striping mechanism are arranged and in control connection with the PLC control system, and the follow-up wire clamping tool and the striping mechanism achieve winding of an automobile solenoid valve coil; the winding mechanism drives a solenoid valve coil framework to conduct winding, the winding displacement guide pin swings leftwards and rightwards to conduct winding displacement, the winding displacement sensor is actually fed back to the PLC control system according to the swing angle alpha of the winding displacement guide pin, and the PLC control system calculates out the winding displacement speed according to the winding displacement calculation formula, so that winding displacement is conducted by dynamically controlling the winding displacement speed of the winding displacement guide pin; the wire hooking mechanism guides a copper wire and conducts pin winding on a left pin from low to high, and fully automatic winding is achieved.

Description

technical field [0001] The invention relates to a coil winding process of an automobile electromagnetic valve. Background technique [0002] The traditional coil winding is wound by hand or semi-automatic machinery. The copper wire is wound by hand, and then the wire is wound mechanically. Finally, the copper wire at the other end is pulled off by hand and wound to another pin. The operation mode has low efficiency, poor effect and high labor cost. There are some winding machines on the market, which first wrap a pin from the inside to the outside, then wind the coil from the outermost lead of the pin, and finally wind the other pin from the inside to the outside. However, since the first pin is bound from the inside to the outside, it is easy to break the copper wire on the outermost circle of the pin during spot welding, causing the coil to be easily damaged and the yield rate to be low. At the same time, when fully automatic winding and hanging, the wire can only be hun...

[0002] The traditional coil winding is wound by hand or semi-automatic machinery. The copper wire is wound by hand, and then the wire is wound mechanically. Finally, the copper wire at the other end is pulled off by hand and wound to another pin. The operation method is inefficient, the effect is poor, and the labor cost is high

There are some winding machines on the market, which first wrap a pin from the inside to the outside, then wind the coil from the outermost lead of the pin, and finally wind the other pin from the inside to the outside. However, since the first pin is bound from the inside to the outside, it is easy to break the copper wire on the outermost circle of the pin when the pin is spot-welded, causing the coil to be easily damaged and the yield rate to be low.

At the same time, when fully automatic winding and hanging, the wire can only be hung from low to high, and then hang down to the bottom of the skeleton. The defect rate is rising, and the general coil winding speed is only 600-800 per hour, and the winding speed needs to be improved

Therefore, in view of the shortcomings of the above-mentioned technical problems in the operation mode of traditional coil winding and the current winding machine, the applicant has developed a wire-guiding needle, a wire sensor, a winding mechanism, a hook-up mechanism, and a fixing clip. The wire tool and the unloading mechanism are respectively connected and controlled with the PLC control system. The follow-up clamping tool and the unloading mechanism realize the winding of the automobile solenoid valve coil; Swing to arrange the cable, the cable sensor will swing according to the angle α of the cable guide pin 实 Feedback to the PLC control system, the PLC control system calculates the speed of the wire according to the calculation formula of the wire, so as to realize the dynamic control of the wire speed of the wire guide needle to carry out the wire; the hooking mechanism guides the copper wire to the left pin by It realizes automatic winding from low to high, which solves the phenomenon that the current winding machine is easy to break the outermost copper wire on the pin and cause the coil to be easily damaged when the pin is spot-welded. Its intelligent High degree of operation, high efficiency, high yield rate, low cost, good effect, easy to use and fast coil winding process for automotive solenoid valves is indeed necessary
