Description

Technical Field

[0001] This utility model belongs to the technical field of coil winding equipment, specifically relating to an ignition coil winding lead assembly. Background Technology

[0002] During the winding of an ignition coil, a clamping robot fixes one end of the lead wire to the coil holder. The lead wire is wound on the holder by rotating it. In the actual winding process, the tension on the wire varies as the coil holder starts to rotate, rotates at a constant speed, and gradually stops rotating. If the tension is too high, the wire will be stretched, affecting the wire itself. If the tension is too low, the wire will be loosely wound on the coil holder, affecting the quality of the coil. Therefore, there is an urgent need for a device that can monitor and adjust the wire tension during the coil winding process. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provide an ignition coil winding lead assembly.

An adjustment assembly, a monitoring assembly, and two sets of wire assemblies are respectively provided on the front end face of the mounting plate. The adjustment assembly and the monitoring assembly are located between the two sets of wire assemblies, with the adjustment assembly located in front of the monitoring assembly. The two sets of wire assemblies include two guide rollers arranged vertically, both of which are rotatably connected to the mounting plate. Multiple sets of wire grooves are formed on the guide rollers, with the diameter of the wire grooves increasing progressively. The adjustment assembly includes an adjustment motor and an adjustment roller. The adjustment motor is fixedly connected to the mounting plate, and the drive shaft of the adjustment motor extends to the front side of the mounting plate. The adjustment roller and... The drive shaft of the drive motor is fixedly connected. A wire-passing hole is provided on the adjusting roller at a position corresponding to multiple wire grooves in the guide roller shaft. The diameter of the wire-passing hole is larger than the diameter of the corresponding wire groove on the guide roller shaft. The monitoring component includes a positioning shaft and a sliding shaft. The positioning shaft is located above the sliding shaft, and both are fixedly connected to the mounting plate. A positioning groove is provided on the positioning shaft at a position corresponding to multiple wire grooves in the guide roller shaft.

[0008] The beneficial effects of this utility model are as follows: by setting up a monitoring component and an adjustment component, when the tension is too high or too low, the wire drives the rotating monitoring wheel to move up and down, and the swing arm drives the angle sensor to rotate, so as to realize the real-time monitoring of the tension of the wire.

Detailed Implementation

[0012] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0013] Example: An ignition coil winding lead assembly, such as Figures 1-2As shown, the system includes a mounting plate 1. An adjustment assembly, a monitoring assembly, and two sets of wire assemblies are respectively provided on the front end face of the mounting plate 1. The adjustment assembly and the monitoring assembly are located between the two sets of wire assemblies, with the adjustment assembly positioned in front of the monitoring assembly. Each set of wire assemblies includes two vertically arranged guide roller shafts 2, both of which are rotatably connected to the mounting plate 1. Multiple wire grooves 3 are formed on the guide roller shafts 2, with the diameter of the wire grooves 3 increasing progressively. The adjustment assembly includes an adjustment motor 4 and an adjustment roller 5. The adjustment motor 4 is fixedly connected to the mounting plate 1, and its drive shaft extends to the front of the mounting plate 1. The adjustment roller 5 is fixedly connected to the drive shaft of the drive motor. The adjustment roller 5 is connected to the multiple wire grooves in the guide roller shafts 2. A threading hole 6 is provided at each of the corresponding positions of the guide roller shaft 2. The diameter of the threading hole 6 is larger than the diameter of the corresponding wire groove 3 on the guide roller shaft 2. The monitoring component includes a positioning shaft 7 and a sliding shaft 8. The positioning shaft 7 is located on the upper side of the sliding shaft 8 and both are fixedly connected to the mounting plate 1. A positioning groove 9 is provided on the positioning shaft 7 at the position corresponding to the multiple wire grooves 3 in the guide roller shaft 2. A sliding seat 10 is sleeved on the positioning shaft 7 and the sliding shaft 8. The sliding seat 10 is slidably connected to both the positioning shaft 7 and the sliding shaft 8. An angle sensor 11 is provided on the rear side of the sliding seat 10. A swing arm 12 is connected to the angle sensor 11. A rotating monitoring wheel 13 rotates at the lower end of the swing arm 12. The position of the rotating monitoring wheel 13 is aligned with the position of the positioning groove 9.

[0014] The upper end of the sliding seat 10 is provided with a mounting groove 14, and a positioning steel ball 15 that cooperates with the positioning groove 9 is provided in the mounting groove 14; a spring 16 is provided on the top of the positioning steel ball 15 to push the positioning steel ball 15 into the positioning groove 9; a sliding handle 17 is fixed on the top of the sliding seat 10, and the sliding handle 17 restricts the spring 16 in the mounting groove 14.

[0015] The principle of this invention is as follows: In use, the wire to be wound is first threaded between the wire assemblies on the front side. A suitable wire groove 3 is selected according to the wire diameter, and the wire passes through the adjusting roller 5, the monitoring assembly, and the rear wire assembly in one go. The rotating detection wheel in the monitoring assembly rests on the wire and records the value of the angle sensor 11 under appropriate tension conditions. During the winding process, when the tension of the wire is too high, the wire will drive the rotating detection wheel to move upward, thereby driving the angle sensor 11 to rotate through the swing arm 12. When the angle exceeds the set range, the adjusting motor 4 drives the adjusting roller 5 to rotate. When the adjusting roller 5 is in its original position, the wire hole 6 is tilted to a certain extent. By changing the tilt angle of the wire hole 6, the friction of the wire can be controlled. When the pressure is too high, the friction of the adjusting roller 5 on the wire is reduced, so that the wire can pass through faster, thereby reducing the tension of the wire. Conversely, the friction of the adjusting roller 5 on the wire is increased. The sliding seat 10 can slide left and right on the positioning shaft 7 and the sliding shaft 8 to monitor wires of different diameters.

[0016] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
