Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating devices, in particular to a winding needle heating device. Background Art
[0002] Winding needles can be divided into square or round shapes according to their uses. They are usually made of metal and are used in different processing industries according to their uses and shapes. They are widely used in mold manufacturing, automated production and other fields, such as winding needles in automated production of lithium batteries.
[0003] When the lithium battery winding needle is winding the core, in order to ensure that the shape of the core is not easily deformed after winding, a heating device is usually used to heat the winding needle so that the winding needle can preheat and solidify the core after winding the core.
[0004] However, when the existing winding needle heating device heats the winding needle, it usually only heats the inside of the winding needle. Since the thermal conductivity of the winding needle material itself is poor, the heat transfer speed is slow, and the preheating speed of the winding core wrapped on the outside of the winding needle is slow, resulting in poor preheating and curing effects of the winding core after the winding needle is heated. In addition, when the existing winding needle heating device heats the winding needle, it is impossible to know the temperature of the winding needle when it is heated, which makes it easier for the winding needle to be overheated, resulting in the winding core in contact with the winding needle to be burned, causing irreversible damage to the winding core.

[0014] 1. The winding needle heating device can quickly conduct heat to the end and inside of the winding needle through the heat conduction ring, heat conduction plate, vertical plate and heat conduction strip, so that the core wound on the winding needle can receive heat in time. At the same time, the heat conduction plate located on the outside of the core can conduct the heat generated by the device to the outside core by thermal radiation, thereby accelerating the preheating speed of the core outside the winding needle and improving the preheating and curing effect of the heating device on the core.

[0024] like Figures 1 to 4 As shown, the needle winding heating device of this embodiment includes a base 6, and card boxes 8 are fixedly connected at the four corners of the base 6. A transparent plate 7 is embedded in the top of the card box 8, and a temperature-changing powder 12 is provided at the bottom of the transparent plate 7. A heat-conducting plate 9 is fixedly connected to the middle of the base 6, and a vertical plate 5 is fixedly connected to one end of the heat-conducting plate 9. A heating ring 4 is fixedly connected to the top of the vertical plate 5. A clamping tube 3 is provided inside the heating ring 4, and a heat-conducting ring 2 is provided on the outer wall of the clamping tube 3. A heat-conducting strip 11 is passed through the bottom of one side wall of the clamping tube 3, and a winding needle 10 is clamped on one side wall of the clamping tube 3.
[0025] Specifically, the base 6 is a flat plate structure with good thermal conductivity. At the same time, a heat insulation board is fixed to the bottom of the base 6 to prevent heat from being conducted to other devices through the base 6, so that the heat is transferred on the device. There are four card boxes 8, and the four card boxes 8 are of the same size and distributed at the four corners of the device, so that it is convenient for the user to know the approximate changes in temperature at various positions on the device, which is beneficial for the user to control and adjust the heating temperature of the device. The transparent plate 7 is made of transparent resin material with a smooth and wear-resistant surface, high temperature resistance, and not easy to deform. The full name of the temperature-changing powder 12 is temperature-sensitive color-changing powder, which is a temperature-sensitive material that can change the molecular structure of the organic matter due to the transfer of electrons at a specific temperature, thereby achieving color change, and each color corresponds to a different color range, so that the user can The color of the temperature-changing powder 12 can be observed to know the temperature of the position at this time. The heat conducting plate 9 is located directly below the winding needle 10, and can directly conduct heat to the winding core outside the winding needle 10 by thermal radiation, so that the inner and outer sides of the winding core can absorb heat in time, thereby improving the preheating and curing effect of the device on the winding core. The heat conducting ring 2 is also made of heat conducting material, so that the heat generated by the heating ring 4 after heating can be smoothly conducted to the heat conducting ring 2, and at the same time will not interfere with the movement of the winding needle 10, thereby facilitating the heating device to heat the winding needle 10. The heating method of the heating ring 4 is electric heating, so that the heating ring 4 can conduct heat to the heat conducting ring 2, and conduct heat to the heat conducting plate 9 and the heat conducting strip 11 through the heat conducting ring 2, so that the heat conducting strip 11 can quickly conduct heat to the winding needle 10 and the winding core outside the winding needle 10.
[0026] Furthermore, one end of the clamping tube 3 is fixedly connected to the connecting tube 1, which is snap-connected to the output end of the winding machine. The winding needle 10 is snap-connected to the connecting tube 1 through the clamping tube 3. The function of the connecting tube 1 is to enable the winding needle 10 to complete subsequent winding and retraction actions, thereby facilitating the winding needle 10 to pass through the heating device smoothly.
[0027] Furthermore, the clamping tube 3 is movably connected to the heating ring 4 through the connecting tube 1, and the thermally conductive ring 2 is movably connected to the heating ring 4 through the clamping tube 3. The clamping tube 3 can clamp and fix the winding needle 10, and at the same time, the heat can be transferred to the thermally conductive strip 11 through the thermally conductive ring 2, so that the thermally conductive strip 11 preheats the winding needle 10 and the winding core on the winding needle 10.
[0028] Furthermore, the heating ring 4 is movably connected to the winding needle 10 through the vertical plate 5 and the base 6. The winding needle 10 can shuttle in the heating ring 4 under the action of the clamping tube 3, so that the winding needle 10, the thermal conductive strip 11 and the thermal conductive ring 2 can all sense the heating ring 4 and generate heat.
[0029] Furthermore, a cavity 13 is opened inside the card box 8, the transparent plate 7 is engaged with the top of the cavity 13, and the temperature-changing powder 12 is filled inside the cavity 13. The cavity 13 can accommodate an appropriate amount of temperature-changing powder 12, so that the temperature-changing powder 12 has sufficient volume to display the color, thereby facilitating the user to observe the color of the temperature-changing powder 12 in the card box 8.
[0030] Furthermore, the top of the thermally conductive strip 11 is engaged with the bottom of the winding needle 10 , which can increase the stability of the thermally conductive strip 11 and reduce the adverse effect of the thermally conductive strip 11 on the winding action of the winding needle 10 .
[0031] Furthermore, the heat conducting plate 9 is movably connected to the winding needle 10 through the base 6. The heat conducting plate 9 can enable the outer side of the winding core wound on the winding needle 10 to absorb the heat generated by the device in time, so that the device can heat the inside and outside of the winding core at the same time, thereby improving the effect of the device on preheating and curing the winding core.
[0032] The method of using this embodiment is as follows: before using the heating device of the winding needle 10, it is necessary to first install the connecting tube 1 on the winding machine, and at the same time install the base 6 at a suitable position on the winding machine, so that the heating ring 4 is in a state of being sleeved on the outside of the clamping tube 3, and then the winding needle 10 is installed into one end of the clamping tube 3, so that the winding needle 10 and the clamping tube 3 are engaged, and at this time the power of the device can be turned on, so that the heating ring 4 starts to generate heat, and then the heat is conducted to the heat-conducting ring 2 on the outside of the clamping tube 3, so that the heat-conducting ring 2 conducts the heat to the heat-conducting strip 11, so that the heat-conducting strip 11 can conduct the heat to the inside of the core while the winding needle 10 is winding the core, so that the inside of the core is heated. Preheating, and at the same time, the vertical plate 5 at the bottom of the heating ring 4 can conduct heat to the heat conducting plate 9, so that the heat conducting plate 9 on the base 6 can heat the winding core on the outside of the winding needle 10, so that the inside and outside of the winding core can be heated at the same time, so that the preheating and curing effects of the winding core are improved. In the process of using this device, the user can observe the color of the temperature-changing powder 12 at the bottom of the transparent plate 7 through the transparent plate 7 on the card box 8 at the four corners of the base 6. When the color of the temperature-changing powder 12 changes to the color corresponding to the set temperature value, it is necessary to adjust and control the temperature of the heating ring 4 in time to avoid the situation where the temperature of the winding needle 10 is too high and causes irreversible damage such as burns to the winding core.
