Description

Technical Field

[0001] The utility model relates to the technical field of electronic components, in particular to a winding device for manufacturing electronic components. Background Art

[0002] Electronic components are components of electronic components and small electrical machines and instruments. They are often composed of several parts. Wirewound resistors are the most commonly used resistor products in power supplies. The basic manufacturing process is to wind the resistance wire on an alumina ceramic rod substrate or other insulating substrate. The resistance wire is an alloy material such as nickel-chromium or manganese-copper. The two ends of the resistance wire are connected to fixed feet, and the outer periphery of the resistance wire is packaged with different packaging materials. With the continuous development of science and technology, the winding devices used for wirewound resistors are also increasingly tending to be diversified. A wire winder is a device commonly used in the manufacture of electronic components. Its main function is to wind a thin wire or a ribbon around an electronic component to form a coil of the electronic component. The principle of the wire winder is to drive the drum or pulley through a motor to drive the wire reel, pull the cable or ribbon from the wire reel, and then wind it around the electronic component through a winding head.

[0003] For example, a winding device for manufacturing electronic components disclosed in a Chinese patent document (publication number: CN220367808U) is disclosed. Although this patent includes a moving frame, a wire-managing roller, an inclined rod and a wire-pressing rod through a wire-managing bracket, the middle frame of the moving frame is provided with a wire-managing roller using a rotating shaft, the middle frame of the moving frame is provided with an inclined rod inclined outwardly, and a wire-pressing rod is provided at the top of the inclined rod body. The metal wire first passes through the inclined rod and the wire-pressing rod to press down the wire, thereby ensuring the tightness of the metal wire during transportation. However, when the metal wire is being transported, its wire-out speed and winding speed cannot be kept completely consistent. Therefore, the wire-pressing rod cannot keep the metal wire tight to a certain extent according to the wire-out speed, thereby easily reducing the winding quality of the metal wire. In addition, when the metal wire is stuck during transportation, the winding cannot be stopped in time, thereby easily causing the problem of the metal wire being pulled and broken.

[0024] An elastic wire pressing device is provided at one end of the limit block 6 , and the elastic wire pressing device includes a moving block 8 , and the lower surface of the moving block 8 is fixedly connected to one end of the limit block 6 .

[0025] A symmetrically distributed support block 81 is fixedly installed on the upper surface of the moving block 8, and a rotating rod 82 is installed on the opposite surfaces of the two support blocks 81 through bearings. One end of the rotating rod 82 penetrates and extends to the front of one of the support blocks 81, and a driving rod 83 is fixedly connected to the outer surface of the rotating rod 82. A swing block 84 is fixedly sleeved on the outer surface of the rotating rod 82, and a wire pressing rod 85 is installed on the front of the swing block 84 through a bearing. The wire pressing rod 85 rotates through the cooperation of the bearing, which plays a role in reducing contact friction when the metal wire is transported. A torsion spring 86 is movably sleeved on the outer surface of the rotating rod 82, and one end of the torsion spring 86 is fixedly connected to the front of the swing block 84. The elastic force of the torsion spring 86 plays a role in swinging through the rotating rod 82 in cooperation with the swing block 84, and the wire pressing rod 85 is driven by the swing block 84 to swing up and down, thereby tightening and relaxing the metal wire.

[0026] The other end of the torsion spring 86 is fixedly connected to the back side of one of the support blocks 81, and the front side of one of the support blocks 81 is respectively fixedly installed with a first limit switch 87 and a second limit switch 88, the first limit switch 87 and the second limit switch 88 are connected with the external PLC control program, so as to have the function of timely power off and shutdown, the opposite surfaces of the two support blocks 81 are both installed with wire wheels 89 through bearings, and the upper surface of the base 1 is fixedly installed with an audible and visual alarm 810, the audible and visual alarm 810 serves to promptly remind the staff to discover and carry out maintenance, and the upper surface of the base 1 is respectively fixedly installed with a wire-releasing bracket body 811 and a wire-winding bracket body 812.

[0027] By setting up an elastic wire pressing device, the metal wire conveyed is automatically elastically tightened according to the winding speed, thereby improving the winding quality of the metal wire. In addition, when the metal wire is over-tightened or over-loose during conveyance, it has an automatic shutdown alarm function, thereby avoiding the wire breakage caused by pulling and winding looseness.

[0028] Working principle: Step 1, the metal wire on the wire-releasing bracket body 811 first passes through the top of the wire pressing rod 85, then passes around the bottom of the wire wheel 89, and finally is wound and connected with the electronic components on the winding bracket body 812. When the metal wire is being transported, the servo motor 3 drives the reciprocating screw rod 4 to rotate. The rotation of the reciprocating screw rod 4 is coordinated with the guide of the limit block 6 and the limit rod 7, so that the thread block 5 drives the moving block 8 to reciprocate through the limit block 6, so that the metal wire is evenly wound;

[0029] Step 2: When the metal wire is released quickly and becomes loose, the restoring elastic force of the torsion spring 86 drives the wire pressing rod 85 to swing upward through the swing rod, so that the wire is continuously elastically taut and transported. When the metal wire is still loose, the continuous upward swing of the swing rod drives the driving rod 83 to swing through the rotating rod 82, so that one end of the driving rod 83 contacts the first limit switch 87, and the power is cut off and the machine is shut down through the external PLC control program, and the sound and light alarm 810 is activated to remind the staff to carry out maintenance.

[0030] Step three, when the metal wire appears slowly, the tension generated by the metal wire will cause the wire pressing rod 85 to drive the swing block 84 to swing downward under the action of the tension, thereby relieving the tension of the metal wire. When the pressure of the wire pressing rod 85 is too large, the swing block 84 drives the driving rod 83 to swing in the opposite direction through the rotating rod 82 until it contacts the second limit switch 88, and then the power is cut off and the machine is shut down through the external PLC control program, thereby avoiding the breakage of the metal wire, and starting the sound and light alarm 810 to remind the staff to carry out maintenance.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
