Description

Technical Field

[0001] The utility model belongs to the field of optical fiber fusion splicing equipment, and specifically relates to a heating furnace and an optical fiber fusion splicer. Background Art

[0002] In the engineering application of optical fiber, after two optical fibers are fusion-spliced, heat shrink tubing is required to protect the connected optical fibers. The heating furnace placed in the optical fiber fusion splicer is a device for heating the heat shrink tubing. After the power is turned on, the heating element in the heater will generate heat to cause the heat shrink tubing to shrink radially.

[0003] Currently, a common solution to improving heat shrink efficiency is to use a metal or alloy with good thermal conductivity to create a U-shaped, V-shaped, or other heating groove that increases the area between the heat shrink tubing and the heating element. The heating resistors are fixed or printed on the upper and lower surfaces of the heating groove. This method uses a larger heating groove. Although it can increase the heated area, the heat shrink tubing is placed directly inside the heating groove during use, resulting in poor contact between the heat shrink tubing and the heating groove, causing significant heat conduction losses, low reliability, and no further improvement in heating efficiency.

[0045] In the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0046] The following is combined with Figure 1-10 The utility model is described in further detail.

[0047] like Figure 1-10 As shown, the utility model discloses a heating furnace, comprising:

[0048] The furnace base 100 has a heating zone therein;

[0049] The furnace cover 200 is connected to the furnace base 100 and is used to open or close the heating zone;

[0050] The heater 300 is installed in the heating zone to heat the product;

[0051] The pressing member 400 is installed on the furnace cover 200 to press the product toward the heater 300.

[0052] The heating furnace of the present invention is used to shrink a heat shrinkable tube on an optical fiber. During processing, the furnace cover 200 is controlled to be opened, and then the optical fiber covered with the heat shrinkable tube is placed on the heater 300 in the heating zone, and then the furnace cover 200 is closed. When the furnace cover 200 is closed, the pressing piece 400 can press on the heat shrinkable tube, and then the heater 300 is turned on to perform heat shrink processing. The interior of the present invention is provided with a pressing piece 400 that can press the heat shrinkable tube toward the heater 300, which can improve the tightness of the contact between the heat shrinkable tube and the heater, so that the heat shrinkable tube shrinks under the simultaneous action of heating and pressure, thereby improving the shrinkage efficiency and shrinkage effect of the heat shrinkable tube when heated, reducing the time for the heat shrinkable tube to shrink on the optical fiber, and improving the efficiency of the optical fiber fusion processing.

[0053] The heater 300 includes:

[0054] The V-shaped heating plate installed in the heating zone has a V-shaped heating groove facing the furnace cover 200. The setting of the V-shaped heating plate is conducive to increasing the heating area in contact with the heat shrink tubing, thereby improving heating efficiency and heat shrinking effect.

[0055] The V-shaped ends of the V-shaped heating plate are rounded.

[0056] The pressing member 400 includes:

[0057] A pressing spring 410 is fixed to the furnace cover 200, and a pressing head is connected to the end of the pressing spring 410 away from the furnace cover 200. The pressing head in the pressing member 400 is used to press the heat shrink tubing. The pressing head is connected to the furnace cover 200 via the pressing spring 410, making it suitable for pressing heat shrink tubing of different sizes. When the heat shrink tubing shrinks and deforms, the pressing head always remains in a tight state due to the elastic force of the pressing spring 410.

[0058] The pressing member 400 further includes:

[0059] A guide tube 420 is fixedly connected to the furnace cover 200 , and a stepped slide 460 is slidably arranged at one end in the guide tube 420 , and the other end of the stepped slide 460 is connected to the top pressure head.

[0060] When relative movement occurs between the top pressure head and the furnace cover 200, the top pressure head drives one end of the stepped slide 460 to move, and the other end of the stepped slide 460 slides in the guide tube 420. The guide tube 420 and the stepped slide 460 cooperate to guide and limit the top pressure head, ensuring that the top pressure head presses vertically on the heat shrink tubing without deviation, thereby ensuring uniformity of the top pressure at different positions.

[0061] The diameter of the stepped slide 460 at the end inserted into the guide tube 420 is smaller than the diameter of the stepped slide 460 at the end connected to the ram.

[0062] The top pressure head comprises:

[0063] A pressing carriage 430 is fixed to the pressing spring 410, and a pressing head body 440 is fixed to the side of the pressing carriage 430 away from the pressing spring 410. The pressing carriage 430 slides within the mounting slot of the furnace cover 200. The pressing carriage 430 slides within the mounting slot of the furnace cover 200 and, under the elastic force of the pressing spring 410, drives the pressing head body 440 to press against the heat shrink tubing, making the movement of the pressing head body 440 more stable.

[0064] The pressing head body 440 is a V-shaped structure, with the V-shaped end of the pressing head body 440 facing the heater 300, so as to facilitate insertion into the V-shaped heating groove of the V-shaped heating plate for pressing.

[0065] The V-shaped end of the pressing head body 440 is provided with a pressing plane 450 for pressing the product. The setting of the pressing plane 450 is conducive to increasing the pressing contact area and improving the pressing effect.

[0066] The furnace cover 200 is rotatably connected to the furnace base 100, and a snap-fit ​​structure is provided between the furnace base 100 and the furnace cover 200 to facilitate the relative opening or closing between the furnace base 100 and the furnace cover 200. The snap-fit ​​structure is a structure in the prior art, for example: an elastic hook is provided on the furnace base 100, and a buckle seat is provided on the furnace cover 200. The furnace base 100 and the furnace cover 200 are relatively closed by the snap-fit ​​cooperation between the elastic hook and the buckle seat. When the furnace base 100 and the furnace cover 200 need to be opened, the elastic hook is controlled to separate from the buckle seat, which is very convenient to operate.

[0067] The utility model also provides an optical fiber fusion splicer, comprising any one of the above-mentioned heating furnaces, for quickly fusing optical fibers.

[0068] The various embodiments in the specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the same or similar parts between the various embodiments. It should be noted that those skilled in the art may make various improvements and modifications to the present application without departing from the principles of the present application, and such improvements and modifications also fall within the scope of protection of the claims of the present application.

[0069] In one embodiment, a computer device is further provided, including a memory and a processor. The memory stores a computer program, and the processor implements the steps in the above method embodiment when executing the computer program.

[0070] In one embodiment, a computer-readable storage medium is provided, on which a computer program is stored. When the computer program is executed by a processor, the steps in the above method embodiment are implemented.

[0071] Those skilled in the art will appreciate that all or part of the processes in the above-described method embodiments can be implemented by instructing the relevant hardware through a computer program. The computer program can be stored in a non-volatile computer-readable storage medium. When executed, the computer program can include the processes of the above-described method embodiments.
