Description

Technical Field

[0001] The utility model relates to the technical field of micro transformers and relates to a coil winding device. Background Art

[0002] A micro transformer is a small-sized electrical device used to change the magnitude of an alternating voltage. It consists of an iron core and windings.

[0003] Among them, the main material of the winding is copper wire. The copper wire is wound around the iron core by a coil winding device. During this process, the copper wire needs to be straightened and continuously wound. At this time, the copper wire itself will be subjected to a large tensile force. However, the copper wire is generally wound on a winding roller for wire feeding. During the production and winding process of the copper wire, a certain section of the copper wire may be twisted, and cracks are likely to appear inside this section of the copper wire, resulting in an increased damage rate of the micro transformer when the high-end copper wire is used to make the winding.

[0004] To solve the above problems, a coil winding device is proposed in this application. Summary of the Utility Model

[0005] The utility model aims at the technical problems existing in the prior art and provides a coil winding device.

[0006] The technical solution for the utility model to solve the above technical problems is as follows: A coil winding device includes a device body, and a monitoring structure is arranged on the device body.

[0007] The monitoring structure includes a test tube. An installation groove is formed in the inner side of one end of the test tube, and a detection ring is movably inserted into the test tube through the installation groove.

[0008] A positioning port is formed through the test tube. A positioning block is installed on the detection ring, and the positioning block is slidably connected to the test tube through the positioning port.

[0009] A fixing rod is installed on the test tube through the positioning port. A contact switch is installed at one end of the fixing rod, and the contact switch is used for electrically connecting with the driving structure of the device.

[0010] A lubricating component is arranged on the test tube.

[0011] A spring is installed on the test tube through the installation groove, and the detection ring is installed at one end of the spring. By setting the spring, it is used to support the detection ring.

[0012] A support rod is installed on the device body, and the test tube is installed at the top of the support rod. By setting the support rod, it is used to support the test tube.

[0013] The lubrication assembly includes an oil tank connected to the inside of the test tube. The test tube is provided with an oil groove through the installation groove, and the oil groove is communicated with the oil outlet end of the oil tank. By setting the lubrication assembly, it is used to lubricate the test tube and its related part structures.

[0014] An oil inlet pipe is connected to the oil tank, and a sealing cap is threadedly connected to the oil inlet pipe. By setting the oil inlet pipe and the sealing cap, it is used to inject oil into the oil tank.

[0015] The test tube is provided with a sponge strip through the oil groove. By setting the sponge strip, it is used to slow down the flow rate of the lubricating oil.

[0016] The beneficial effects of the present utility model are:

[0017] By setting the monitoring structure, the deformed copper wire presses the detection ring, causing the detection ring to move, so that the positioning block touches the contact switch, causing the device to stop operating, and thus achieving the purpose of reminding the operator of the problem of the copper wire and trying to avoid the copper wire with torsion being wound around the iron core, which helps to reduce the damage rate of the micro-transformer;

[0018] By setting the lubrication assembly, the lubricating oil in the oil tank flows into the test tube to soak the sponge strip. Subsequently, the soaked sponge strip is used to lubricate the test tube and its related part structures for a long time, thus achieving the effect of ensuring the sensitivity of the detection ring as much as possible.

In the following description, details are set forth for the purpose of explanation. It should be understood that those skilled in the art can recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid unnecessary details from obscuring the description of the present invention. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope that conforms to the principles and features disclosed in the present application.

[0031] Refer to Figures 1-4, a coil winding device, including a device body 1, on which a monitoring structure 3 is provided. The monitoring structure 3 is used to monitor whether there is torsion in the copper wire. The monitoring structure 3 includes a test tube 301. An installation groove 302 is opened on the inner side of one end of the test tube 301. A detection ring 304 is movably inserted into the test tube 301 through the installation groove 302. The inner diameter of the detection ring 304 is equal to the inner diameter of the test tube 301. A positioning port 305 is penetrated through the test tube 301. A positioning block 306 is installed on the detection ring 304. The positioning block 306 is slidably connected to the test tube 301 through the positioning port 305. The positioning block 306 can slide within the positioning port 305. The positioning block 306 and the positioning port 305 cooperate to limit the movement of the detection ring 304. A fixing rod 307 is installed on the test tube 301 through the positioning port 305. A contact switch 308 is installed at one end of the fixing rod 307. The contact switch 308 is used to be electrically connected to the driving structure of the device. When the contact switch 308 is touched, the device will stop the winding operation;

[0032] Among them, it should be noted that the copper wire passes through the inside of the test tube 301, and the outer diameter of the copper wire is equal to the inner diameter of the detection ring 304. In addition, when there is a twist at a certain place of the copper wire, the copper wire at that place has been deformed, so it cannot pass through the detection ring 304 normally, and in the existing technology of this device, the copper wire has been straightened;

[0033] According to the above technical solution, specifically, the straightened copper wire passes through the test tube 301 and is wound around the outside of the iron core. When there is a twist at a certain place of the copper wire, the deformed copper wire presses the detection ring 304, so that the detection ring 304 moves. The movement of the detection ring 304 drives the movement of the positioning block 306, and then the positioning block 306 touches the contact switch 308, causing the device to stop working, so as to remind the operator of the problem of the copper wire and try to avoid winding the copper wire with torsion around the iron core, which helps to reduce the damage rate of the micro-transformer.

[0034] Refer to Figure 3 , a spring 303 is installed on the test tube 301 through the installation groove 302. The detection ring 304 is installed at one end of the spring 303. It should be noted that the spring 303 is used to support the detection ring 304, which helps to prevent the detection ring 304 from moving without being stressed.

[0035] Refer to Figure 1 and Figure 2 , a support rod 2 is installed on the device body 1. The test tube 301 is installed at the top of the support rod 2. The support rod 2 is used to support the test tube 301.

[0036] Refer to Figure 3 and Figure 4The test tube 301 is provided with a lubricating assembly 4, which includes an oil tank 401 connected to the inside of the test tube 301. The test tube 301 is provided with an oil tank through the mounting groove 302, and the oil tank is connected to the oil outlet end of the oil tank 401. The oil tank 401 is loaded with lubricating oil, and the lubricating oil flows into the oil tank to lubricate the test tube 301 and its related parts and structures;

[0037] The oil tank 401 is connected with an oil inlet pipe 402, and a sealing cap 403 is threadedly connected to the oil inlet pipe 402. The oil inlet pipe 402 is used to inject oil into the oil tank 401, and the sealing cap 403 is used to seal the oil inlet pipe 402;

[0038] The test tube 301 is provided with a sponge strip 404 through the oil groove, and the sponge strip 404 is used to slow down the flow rate of the lubricating oil;

[0039] According to the above technical solution, specifically, the lubricating oil in the oil tank 401 flows into the test tube 301 to soak the sponge strip 404, and then the soaked sponge strip 404 is used to lubricate the test tube 301 and its related parts for a long time, thereby achieving the effect of ensuring the sensitivity of the detection ring 304 as much as possible.

[0040] Working principle:

[0041] In the coil winding device, the straightened copper wire passes through the test tube 301 and is wound around the outside of the iron core. When there is twisting at a certain point of the copper wire, the deformed copper wire squeezes the detection ring 304, so that the detection ring 304 moves. The movement of the detection ring 304 drives the movement of the positioning block 306, and then the positioning block 306 touches the contact switch 308, so that the device stops operating, thereby reminding the operator of the problem of the copper wire and avoiding the copper wire with twisting force to be wound around the iron core as much as possible, which helps to reduce the damage rate of the micro transformer.

[0042] In the coil winding device, the lubricating oil in the oil tank 401 flows into the test tube 301 to soak the sponge strip 404. Subsequently, the soaked sponge strip 404 is used to lubricate the test tube 301 and its related parts for a long time, thereby achieving the effect of ensuring the sensitivity of the detection ring 304 as much as possible.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.

[0044] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations therein.
