Abstract
Description
Technical Field
[0001] This invention relates to the field of assembly line heating structure technology, specifically to a heating device and production line. Background Technology
[0002] In product manufacturing, heating is often an indispensable processing step. Traditional heating devices are heating coils, similar to the heating plate at the bottom of a rice cooker. The workpiece to be heated is placed on the heating plate for heating treatment. However, only the side of the workpiece closest to the heating plate can be sufficiently heated, and the heating of other parts is uneven, resulting in poor overall heating uniformity of the workpiece. Summary of the Invention
[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect of poor heating uniformity of workpieces by heating plates in the prior art, thereby providing a heating device and production line.
[0004] A heating device, comprising:
[0005] A bracket, wherein a heating channel is formed on the inner side of the bracket, and the heating channel has at least one open end;
[0006] A heating element is disposed on the bracket and is positioned facing the heating channel.
[0007] The heating element includes:
[0008] The wire is wound in a spiral shape around the support.
[0009] The heating element also includes:
[0010] A magnetic component is disposed close to the winding wire, which is located between the magnetic component and the bracket.
[0011] There are multiple magnetic components, which are arranged around the heating channel, with a gap between adjacent magnetic components.
[0012] The heating element also includes:
[0013] The first insulating layer is attached to and covers the outside of the integral structure formed by the winding and the magnetic component, thereby isolating the magnetic component and the winding from the heat insulation layer.
[0014] The first insulating layer is made of epoxy resin material.
[0015] The heating device also includes:
[0016] The outer shell is fitted onto the outside of the bracket, and the outer shell and the bracket form a heat insulation layer.
[0017] The insulation layer is suitable for being filled with a cooling medium.
[0018] The outer shell is provided with an outflow conduit and an inflow conduit that connect to the heat insulation layer. The cooling medium is a fluid cooling medium that forms a circulating fluid loop within the heat insulation layer.
[0019] A second insulating layer is provided on the surface of the outer casing facing the heat insulation layer.
[0020] A production line comprising:
[0021] In any of the above-described heating devices, the bracket has two open ends, one at the channel inlet and the other at the channel outlet.
[0022] The technical solution of this invention has the following advantages:
[0023] 1. The present invention provides a heating device, comprising: a bracket, wherein a heating channel is formed on the inner side of the bracket, the heating channel having at least one open end; and a heating element disposed on the bracket, the heating element being disposed toward the heating channel.
[0024] The support frame houses a cylindrical heating channel. Workpieces enter the heating channel through an opening on the frame, with the heating element's heating end facing the channel. When the workpiece is inside the heating channel, it is surrounded by the channel, meaning it is surrounded by the heating element, ensuring more uniform heating from all directions. The cylindrical frame also facilitates automatic workpiece loading and unloading, enabling batch processing on the production line. Multiple workpieces can be heated simultaneously within the channel, depending on their specific process requirements. An insulation layer prevents heat loss, reducing the overall impact of the heating device on the external environment. This is particularly beneficial when used on production lines, as it reduces the distance between adjacent workstations, resulting in a more compact overall production line structure.
[0025] 2. The heating device provided by the present invention, wherein the heating element comprises: a winding wire, which is spirally wound on the bracket.
[0026] The wire wound around the support generates an alternating magnetic field when energized. For workpieces primarily made of ferromagnetic materials, this alternating magnetic field heats them up, resulting in more uniform heating of the entire workpiece. It can also provide targeted and uniform heating to specific ferromagnetic portions of the workpiece.
[0027] 3. The heating device provided by the present invention further includes: a first insulating layer, which is attached to and covers the outside of the integral structure formed by the winding and the magnetic element, so that the magnetic element and the winding are isolated from the heat insulation layer.
[0028] The first insulation layer wraps the winding and magnetic components and isolates them from the heat insulation layer, thus providing insulation and ensuring safe use.
[0029] 4. In the heating device provided by the present invention, the first insulating layer is made of epoxy resin material.
[0030] The first insulating layer not only serves as insulation but also dissipates heat, transferring heat to the insulation layer.
[0031] 5. In the heating device provided by the present invention, the heat insulation layer is suitable for being filled with a cooling medium.
[0032] The winding generates an alternating magnetic field, creating a high-temperature area within the heating channel. To reduce the outward diffusion of the high-temperature environment and its impact on other workstations and equipment, the cooling medium in this design is located inside the insulation layer, which is wrapped around the outside of the support. Therefore, the insulation layer intercepts the path of the high-temperature environment spreading to the outside of the support, and the cooling medium absorbs the dissipated heat, thereby reducing the heat loss to the outside of the heating device.
[0033] 6. The heating device provided by the present invention has an outflow conduit and an inflow conduit on the outer shell that communicate with the heat insulation layer, and the cooling medium is a fluid cooling medium that forms a circulating water path within the heat insulation layer.
[0034] The circulating water path formed by the fluid cooling medium can carry away heat in a continuous cycle, allowing the insulation layer to be continuously replenished with cooling medium, ensuring that the insulation layer has a continuous heat absorption and dissipation capacity.
[0035] 7. The heating device provided by the present invention has a second insulating layer on the surface of the outer shell facing the heat insulation layer.
[0036] The second insulation layer can further provide insulation, improving the overall safety of the heating device. Attached Figure Description

[0046] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0047] Example 1
[0048] This embodiment provides a heating device, such as... Figure 1 As shown, it includes: a support 1, which is a cylindrical structure with at least two open ends, and a heating channel 11 is formed on the inner side of the support 1; and a heating element, which is disposed on the support 1 and is positioned facing the heating channel 11.
[0049] The shape of the bracket 1 is not specifically limited. In this embodiment, for example... Figure 1 As shown, the function of the support 1 is explained using a cylindrical support 1 as an example. The cylindrical shape can be understood as the support 1 having a uniform, circular cross-section along the length of the heating channel 11. The cylindrical support 1 forms a cylindrical heating channel 11 within itself. The workpiece can enter the heating channel 11 through the open end of the support 1, with the heating end of the heating element facing the heating channel 11. When the workpiece is inside the heating channel 11, it is surrounded by the heating channel 11, i.e., surrounded by the heating element, thus allowing the workpiece to receive more uniform heating from all directions. Simultaneously, the cylindrical support 1 facilitates automatic entry and removal of workpieces, simplifying batch processing on the production line. Multiple workpieces can also be heated simultaneously within the heating channel 11 according to the different process requirements of each workpiece. As an alternative implementation, the support can be a non-cylindrical structure whose cross-sectional size and / or shape varies along the length of the heating channel 11.
[0050] The specific form of the heating element is not limited. In this embodiment, the heating element uses electromagnetic heating. As an alternative implementation, the heating element can be other electric heating components or other heating components that can generate heat themselves.
[0051] Based on the above embodiments, as a further defined embodiment, an outer shell 5 is also fitted onto the outside of the support, and the outer shell 5 and the support 1 form a heat insulation layer 51. The heat insulation layer 51 can prevent heat from dissipating outward and reduce the overall impact of the heating device on the external environment. Especially when applied to a production line, it can reduce the distance between adjacent workstations and make the overall structure of the production line more compact.
[0052] In this embodiment, as Figure 2 As shown, the support 1 is a cylinder with a circular cross-section. Alternatively, the support 1 can have a polygonal cross-section. The openings on the support 1 are for workpiece entry and exit. In this embodiment, the support 1 has two openings, one for workpiece entry and the other for workpiece exit. Alternatively, the support 1 can have only one opening end, with the same opening shared for workpiece entry and exit from the heating channel 11. Another alternative implementation is a Y-shape, with openings at all three ends, allowing for more entry and exit routes for the workpiece, facilitating adaptation to different production lines. When the support 1 is Y-shaped, the cross-section of the support 1 refers to the cross-section of the workpiece's movement path, still satisfying the requirement of a circular or polygonal cross-section.
[0053] Among them, bracket 1 is made of heat-resistant insulating material.
[0054] Based on the above embodiments, as a further limiting embodiment, such as... Figures 1-2As shown, the heating element includes a winding 2, which is spirally wound around the support 1. The winding 2 wound around the support 1 generates an alternating magnetic field when energized. For workpieces primarily made of ferromagnetic materials, the workpiece will heat up within this alternating magnetic field. This results in more uniform heating of the entire workpiece, and also allows for targeted and uniform heating of the ferromagnetic material portions of the workpiece.
[0055] Furthermore, regarding the specific principle of the alternating magnetic field generated by winding 2, such as... Figure 3 As shown, the winding 2 is connected to the control module, which includes a filter and rectifier module, a resonant module, a switching power supply module, and a microcontroller module. The input of the filter and rectifier module is connected to the mains power, and its output is connected to the input of the resonant module. The output of the resonant module is connected to the winding 2. The input of the switching power supply module is connected to the output of the filter and rectifier module, and its output is connected to the input of the microcontroller module, thus supplying power to the microcontroller module. The output of the microcontroller module is connected to the resonant module, controlling its oscillation to generate an alternating magnetic field within the heating channel 11 surrounded by the winding 2.
[0056] Based on the above embodiments, as a further limiting embodiment, such as... Figure 2 As shown, the heating element further includes a magnetic element 3, which is disposed near the winding 2, and the winding 2 is located between the magnetic element 3 and the bracket 1.
[0057] Specifically, magnetic component 3 is a magnetic strip.
[0058] Based on the above embodiments, as a further limiting embodiment, such as... Figure 1 , Figure 2 As shown, the heating element further includes a first insulating layer 4, which adheres to and covers the outside of the integral structure formed by the winding 2 and the magnetic element 3, thereby isolating the magnetic element 3 and the winding 2 from the heat insulation layer 51. The first insulating layer 4 wraps around the winding 2 and the magnetic element 3 and isolates them from the heat insulation layer 51, thus providing insulation and ensuring safe use.
[0059] Based on the above embodiments, as a further limiting embodiment, such as... Figure 1 , Figure 2 As shown, the first insulating layer 4 is made of epoxy resin. The first insulating layer 4 not only serves as insulation but also as heat dissipation, transferring heat to the heat insulation layer 51.
[0060] Based on the above embodiments, as a further limiting embodiment, such as... Figure 1 , Figure 2As shown, the heat insulation layer 51 is suitable for being filled with a cooling medium. The winding 2 generates an alternating magnetic field, forming a high-temperature region within the heating channel 11. To reduce the outward diffusion of the high-temperature environment and its impact on other workstations and equipment, in this design, the cooling medium is located inside the heat insulation layer 51, which wraps around the outside of the support 1. Therefore, the heat insulation layer 51 intercepts the path of the high-temperature environment spreading to the outside of the support 1, and the cooling medium absorbs the dissipated heat, thereby reducing the heat loss to the outside of the heating device.
[0061] Based on the above embodiments, as a further limiting embodiment, such as... Figure 1 , Figure 2 As shown, the outer shell 5 is provided with an outflow conduit 52 and an inflow conduit 53 connecting the heat insulation layer 51. The cooling medium is a fluid cooling medium, which forms a circulating water channel within the heat insulation layer 51. The circulating water channel formed by the fluid cooling medium can circulate and remove heat, allowing the heat insulation layer 51 to be continuously replenished with cooling medium, ensuring that the heat insulation layer 51 has a continuous heat absorption and dissipation capacity.
[0062] Specifically, in Figure 1 From this perspective, the opening at the top of bracket 1 is the channel outlet 13, and the opening at the bottom of bracket 1 is the channel inlet 12. Figure 2 The outflow conduit 52 and the inflow conduit 53 are respectively provided at both ends of the support 1 along its length, so that the cooling medium can dissipate heat fully within the heat insulation layer 51. As an alternative embodiment, the outflow conduit 52 and the inflow conduit 53 are arranged adjacent to each other.
[0063] In this embodiment, the cooling medium is water. As an alternative implementation, the cooling medium can be replaced with other coolants.
[0064] Based on the above embodiments, as a further limiting embodiment, such as... Figure 1 , Figure 2 As shown, a second insulating layer 41 is provided on the surface of the outer casing 5 facing the heat insulation layer 51. The second insulating layer 41 can further provide insulation and improve the overall safety of the heating device.
[0065] There are no restrictions on the application of the heating device. In this embodiment, the heating device is used on a production line, including: the heating device described in any of the above schemes, wherein the bracket 1 has two open ends, namely the channel inlet 12 and the channel outlet 13. For production lines where products require heating, using the heating device in this embodiment as a heating station facilitates assembly line production operations.
[0066] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
