Description

Technical Field

[0001] The utility model relates to the technical field of coil winding equipment, in particular to a disc coil winding tension control structure. Background Art

[0002] The coil winding machine is a professional equipment, mainly used to wind wires or cables into various electromagnetic coils according to a certain pattern. The wires or cables on the spool are wound onto the reel on the winding head as required. The winding head is controlled by the servo system to rotate and move to achieve precise winding of the coil. When the coil reaches the predetermined number of turns, the control system will send a signal to stop winding, and the take-up system will neatly collect the wound coils.

[0003] For example, the Chinese patent application "An Automatic Winding Machine for Transformer Coils," with publication number CN211604917U, includes a loading conveyor mechanism, a first winding mechanism, a second winding mechanism, and a discharge conveyor mechanism. The first and second winding mechanisms are symmetrically arranged between the loading conveyor mechanism and the discharge conveyor mechanism. The loading conveyor mechanism moves a jig carrying a winding die to a corresponding position. The first and second winding mechanisms respectively secure the ends of the winding die and can drive the winding die to corresponding positions, then drive the winding die to rotate and wind the coil. When winding is completed, the first and second winding mechanisms can drive the winding die to move to the discharge conveyor mechanism, where the winding die is discharged and conveyed.

[0004] Although the above-mentioned existing technology can realize the winding of the coil, during the winding process, the unwinding roller is rotated by the traction of the winding machine, and insufficient tension is likely to occur when the coil is unwound. After the coil is wound, it may be in a loose state, resulting in the coil size being too large, which does not meet the expected compactness and flatness requirements. It may also cause the wires inside the coil to be arranged not tightly enough and the density to be insufficient, thereby affecting the electrical performance and mechanical strength of the coil. Therefore, it does not meet the existing needs. In this regard, we propose a disc coil winding tension control structure. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figure 1-5 The present invention provides an embodiment of a disc coil winding tension control structure, comprising a base 1, a support frame 2 provided on one side of the upper end surface of the base 1, and the support frame 2 is welded and fixed to the base 1; and further comprising:

[0026] The unwinding mechanism is arranged on one side of the support frame 2. The unwinding mechanism consists of a side baffle 3 and an unwinding roller 4. The side baffle 3 and the unwinding roller 4 are movably matched, and the side baffle 3 on one side is rotated with the support frame 2 through a rotating shaft. A tension detection mechanism is provided between the side baffle 3 and the unwinding roller 4. The coil is pre-wound on the outside of the unwinding roller 4, and the side baffle 3 limits the coil on the side.

[0027] The brake disc 5 is arranged at the outer side position of the support frame 2 corresponding to the unwinding mechanism, and the axis of the brake disc 5 is fixed to the rotating shaft of the side baffle 3 through a coupling, and a brake actuator is provided at the rear end of the brake disc 5.

[0028] During use, when the tension of the unwinding mechanism decreases, the brake actuator is started through the single-chip microcomputer, the hydraulic system starts to work, and the master cylinder generates hydraulic pressure. This hydraulic pressure is transmitted to the brake piston 8 through the brake oil pipe. The brake piston 8 moves under the action of the hydraulic pressure. The movement of the piston pushes the mechanism in the brake caliper 6 to move the brake pad 7 toward the brake disc 5. The brake pad 7 is in close contact with the brake disc 5. Due to the friction between the two, resistance is generated. This resistance acts on the unwinding mechanism, slowing down or preventing its rotation, thereby adjusting the tightness of the coil. As the brake pad 7 contacts the brake disc 5, the tension gradually increases, and the tightness of the coil is adjusted. At the same time, the pressure sensor 13 continues to monitor the tension changes and feeds back real-time data to the single-chip microcomputer. The single-chip microcomputer continues to adjust the working state of the brake actuator based on the feedback data to keep the coil within the appropriate tightness range.

[0029] See also Figure 3 and Figure 4The tension detection mechanism includes a tension detection hole 9, which is arranged on the side of the side baffle 3 near the unwinding roller 4. There are protrusions 10 in front and behind the tension detection hole 9, and detection grooves 12 are provided in front and behind the upper and lower ends of the unwinding roller 4. The protrusion 10 extends to the inside of the detection groove 12, and the protrusion 10 and the detection groove 12 are slidably matched. The central angle of the detection groove 12 is thirty degrees. Through the relative rotation of the protrusion 10 and the detection groove 12, the force generated during the contact process is monitored, so as to understand the tension value.

[0030] See also Figure 4 and Figure 5 A pressure sensor 13 is installed on one side of the detection groove 12. The output end of the pressure sensor 13 is connected to the single-chip microcomputer, and the output end of the single-chip microcomputer is connected to the input end of the brake actuator. The tension detection mechanism can monitor the tension in real time during the operation of the unwinding mechanism, so that it can respond in the first time to ensure the winding quality of the coil.

[0031] See also Figure 3 A mounting hole 11 is provided on the other side of the side baffle 3, and a connecting shaft 14 is provided between the mounting holes 11 of the side baffles 3 on both sides. Both ends of the connecting shaft 14 are fixed to the mounting holes 11, and the outer wall of the connecting shaft 14 is rotatably connected to the unwinding roller 4. Torsion springs 15 are installed on the outside of both ends of the connecting shaft 14, and the two ends of the torsion spring 15 are respectively fixed to the side baffle 3 and the unwinding roller 4, providing a prerequisite for the relative rotation of the two. At the same time, under the action of the torsion spring, support force is provided for the side baffle 3 and the unwinding roller 4 to ensure overall stability.

[0032] See also Figure 1 and Figure 2 The brake actuator includes a brake caliper 6, and the brake caliper 6 is fixed to the support frame 2 by screws. Brake pistons 8 are installed on both sides of the front end opening of the brake caliper 6. A brake pad 7 is installed on one side of the brake piston 8. The brake pad 7 and the brake piston 8 are fixed by bolts, and the rear end of the brake disc 5 is located between the two brake pads 7. The precise control of the brake actuator ensures the tightness and consistency of the coil during the winding process, improves the winding quality of the coil, and helps to reduce the deformation, looseness and other problems of the coil, thereby improving the performance and service life of the coil.

[0033] Working principle: When in use, the unwinding mechanism is pulled by the winding machine, driving it to rotate and gradually unwinding the coil. The unwinding mechanism is composed of a side baffle 3 and an unwinding roller 4, which are movably installed. When the winding machine is pulled, the unwinding roller 4 rotates first, and the traction force generated at the first time of rotation is large, which can make the coil instantly tightened. At the same time, the detection groove 12 on the unwinding roller 4 and the protrusion 10 of the side baffle 3 rotate relative to each other, so that the two are instantly fitted and come into contact with the pressure sensor 13. As the traction stabilizes, the tension of the unwinding roller 4 will slowly decrease. At this time, the pressure generated by the protrusion 10 on the pressure sensor 13 decreases. If the pressure value is lower than the set value, it means that the coil is less tight during the unwinding process. The brake actuator is turned on by the single-chip microcomputer to provide resistance to the rotation of the unwinding mechanism, so that the coil remains tight during the unwinding process.
