[0038] In the related art, the fiber optic image transmission glass element needs to undergo four thermal processing steps during the processing. Among them, in the heating step in the twisting process, the fiber optic image transmission glass workpiece 1 that needs to be twisted is placed in a heating furnace on an existing machine and equipment for heating, thereby achieving preheating and annealing effects to ensure that the workpiece 1 does not crack at room temperature.

[0039] The current workpiece 1 is installed on the machine equipment, and the preheating and annealing of the workpiece 1 are carried out in the heating furnace. The heating furnace is mainly composed of heating wire, heating furnace core, insulation cotton, furnace shell, and the heating furnace control is composed of accessories such as host computer and power regulator. The heating furnace heats a single workpiece 1 through the process program to achieve the preheating or annealing effect of the workpiece 1. However, the efficiency of single preheating and annealing is low, and the heating furnace on the machine equipment will be occupied when heating the workpiece 1, resulting in low utilization rate of the machine equipment and high power consumption.

[0040] In view of this, an embodiment of the present application proposes a heating device to effectively solve the aforementioned problem.

[0041] See also Figures 1 to 5 As shown, an embodiment of the present application discloses a heating device, including a furnace body 100 , a storage rack 200 , a heating component and a heating control system 400 .

[0042] Specifically, the furnace body 100 has a first heating chamber 110 and a second heating chamber 120, and the first heating chamber 110 and the second heating chamber 120 are both provided with a rack 200, and the rack 200 is used to place multiple workpieces 1 to be heated; the heating component is used to heat the first heating chamber 110 and the second heating chamber 120 to achieve preheating or annealing effect of the workpiece 1; the heating control system 400 is electrically connected to the heating component, and the heating control system 400 is used to control the heating component.

[0043] Wherein, a plurality of workpieces 1 to be heated can be placed in the first heating chamber 110 and the second heating chamber 120 , which can improve the heating efficiency of the workpieces 1 .

[0044] In the embodiment of the present application, a first heating chamber 110 and a second heating chamber 120 are provided in the furnace body 100, and a rack 200 is provided in the two heating chambers, which can be used to place multiple workpieces 1 to be heated. The two heating chambers can respectively place workpieces 1 to be preheated and workpieces 1 to be annealed, or multiple workpieces 1 to be preheated, which helps to improve the heating efficiency. At the same time, the use of a heating component to heat multiple workpieces 1 in the first heating chamber 110 and the second heating chamber 120 can improve the utilization efficiency of the heat of the heating component.

[0045] In this embodiment, the workpiece 1 to be heated can be specifically an optical fiber image transmission glass element. The heating device of this embodiment can be used for batch preheating of optical fiber image transmission elements before precision thermoforming, such as preheating before tapering of optical fiber cones, preheating before twisting of optical fiber invertors, and preheating before bending of light guide rods, etc. It can effectively shorten the processing time of precision thermoforming, improve processing efficiency, and greatly reduce the investment cost of precision thermoforming equipment. At the same time, it can also recycle part of the waste heat of the workpiece 1, which is both energy-saving and environmentally friendly.

[0046] In some embodiments of the present application, see Figures 1 to 3 As shown, the furnace body 100 includes a furnace cover 130, a bottom plate 140 and a furnace wall 150. The furnace wall 150 and the bottom plate 140 enclose a receiving cavity, and the furnace cover 130 is set on the top of the furnace wall 150. Among them, the first heating cavity 110 and the second heating cavity 120 are located in the receiving cavity. Specifically, the bottom plate 140 and the furnace wall 150 enclose a receiving cavity for placing the workpiece 1 to be heated, and the furnace cover 130 is set on the upper end of the furnace wall 150, so that the receiving cavity forms a closed space, which is conducive to reducing heat loss, thereby helping to ensure heating efficiency.

[0047] In a possible implementation, the furnace cover 130 is connected to the furnace wall 150 in a flippable manner. The accommodating cavity can be connected to the outside by flipping the furnace cover 130, so that the workpiece 1 can be easily taken in and out.

[0048] It is worth to understand that in some other embodiments, the furnace cover 130 may also be installed on the furnace wall 150 in other ways, which is not limited here.

[0049] In some embodiments of the present application, the furnace wall 150 includes a plurality of side panels, and the furnace wall 150 is surrounded by the plurality of side panels.

[0050] Furthermore, the side panels are made of thermal insulation board material. Alternatively, the surface of at least one of the bottom plate 140 and the side panels is paved with thermal insulation material.

[0051] In some embodiments of the present application, the bottom plate 140 is made of a heat-insulating plate. On the one hand, the heat-insulating plate can effectively block the heat from being transferred to the outside, which is conducive to improving the capacity utilization rate; on the other hand, the heat-insulating plate can effectively block the heat from being transferred to the heating control system 400 through the bottom plate 140, which can effectively protect the heating control system 400.

[0052] Furthermore, the bottom plate 140 and the furnace wall 150 may also be provided with heat insulating materials to reduce heat loss in the furnace body 100, thereby helping to reduce energy consumption.

[0053] In some other embodiments of the present application, the bottom plate 140 and the inner wall of the furnace wall 150 may also be provided with heat-insulating materials to achieve a heat-insulating effect. For example, heat-insulating cotton is provided on the bottom plate 140 to improve the heat-insulating effect of the bottom plate 140. For another example, heat-insulating cotton material is provided on at least one of the inner wall and the outer wall of the furnace wall 150 to improve the heat-insulating effect of the furnace wall 150.

In this way, the heating of the workpiece 1 to be heated can be achieved. Compared with radiation heat transfer, the heat in the heating device of this embodiment is directly transferred to the workpiece 1 to be heated through the rack 200, which can improve the heat transfer efficiency and help improve the heating efficiency.

[0055] In some embodiments of the present application, the heating element 310 includes a heating wire and a heating plate, and the heating wire is used to heat the heating plate. Specifically, the heating plate abuts against the rack 200, and the heating plate is connected to the rack 200, which can effectively increase the contact area between the heating element 310 and the rack 200, thereby improving the heat transfer efficiency and helping to improve the heating efficiency.

[0056] In a possible implementation, the heating plate is a cast copper plate. The heating plate made of copper has a high thermal conductivity, which can effectively ensure the heat transfer efficiency and help ensure the heating efficiency.

[0057] In some embodiments of the present application, see Figure 2 and Figure 4 As shown, a plurality of independent areas are formed in the first heating chamber 110. In this way, the influence of the external temperature on the workpiece 1 can be reduced, which is conducive to ensuring the stable heating of the workpiece 1. Each independent area can be used for heating the workpiece 1.

[0058] In this embodiment, the heat generated by the heating element 310 is transferred to the rack 200 through the heating plate, and then transferred to the workpiece 1 to be heated through the rack 200. Even if the preheating areas are separated from each other, it is possible to preheat the workpiece 1 to be heated in different areas.

[0059] In some embodiments of the present application, see Figure 2 and Figure 4 As shown, a plurality of independent areas are formed in the second heating chamber 120. In this way, the influence of the external temperature on the workpiece 1 can be reduced, which is conducive to ensuring the stable heating of the workpiece 1. Each independent area can be used for heating the workpiece 1.

[0060] In some embodiments of the present application, the rack 200 is provided with a plurality of placement stations 210 , and each placement station 210 is used for placing a workpiece 1 to be heated.

[0061] In a possible implementation manner, the placement station 210 is in the form of a groove that matches the shape of the workpiece 1 to be heated so as to accommodate the workpiece 1 to be heated.

[0062] In some embodiments of the present application, see Figure 5 and Figure 6 As shown, the heating control system 400 includes an electric control box 410, a temperature controller 420 and a power regulator. The temperature controller 420 and the power regulator are both installed in the electric control box 410. The temperature controller 420 is electrically connected to the power regulator, and the power regulator is used to control the heating power of the heating element 310. In this way, the temperature controller 420 controls the heating power of the heating element 310 through the real-time power of the power regulator, and can change the heating power of the heating component, thereby realizing the adjustment of the heating power of the heating device, thereby changing the heating temperature.

[0063] In the above embodiment, the temperature controller 420 , the power regulator and the heating element 310 are all connected to a power source, and the power source is used to supply power to the temperature controller 420 , the power regulator and the heating element 310 .

[0064] In the embodiment of the present application, the heating control system 500 further includes a switch assembly 430 , which is installed on the electric control box 410 , and is used to control the on and off of the power supply.
