Coil winding process for automobile solenoid valve

Abstract

A coil winding process for an automobile solenoid valve of the present invention, comprising a PLC control system, and a wire guide pin, a wire sensor, a winding mechanism, a hooking mechanism, an unloading mechanism and a fixed clamping wire respectively connected to the PLC control system tool, and a follow-up clamping tool connected with the winding mechanism. The present invention connects and controls with the PLC control system respectively by being provided with a wire arranging guide pin, a wire arranging sensor, a winding mechanism, a hooking mechanism, a fixed clamping tool and an unloading mechanism, and the follow-up clamping tool and the unloading mechanism realize the automatic control of the vehicle. The coil of the solenoid valve is wound; the winding mechanism drives the coil frame of the solenoid valve to wind the coil, and the wire guide pin swings left and right to arrange the wires, and the wire guide sensor swings according to the angle α of the wire 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 Foot binding from low to high, which realizes fully automatic winding.

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
