Description

Technical Field

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

[0002] In fiber optic communication engineering, the spliced ​​optical fibers need to be reinforced with heat-shrink tubing. However, existing heating furnaces have the following problems: current mainstream fusion splicers are equipped with only a single heating furnace, heating one core takes about 30 seconds, while splicing one core only takes 10 seconds. During emergency repairs, the heating process becomes a bottleneck in efficiency, causing the overall operation speed to drop by more than 50%. To overcome these problems, dual heating furnaces have emerged in the existing technology. However, existing dual heating furnaces generally achieve dual-station heating by connecting two sets of independent heating furnaces in parallel, with a total of four heating elements. However, the simultaneous operation of four heating elements requires a large amount of power. Due to the excessive power consumption, the fusion splicer's battery power is insufficient, and in practical applications, heating can only be done alternately, resulting in poor efficiency improvement.

[0034] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0035] Example 1

[0036] like Figures 1-4As shown, a dual-unit heating furnace includes: a furnace body 1; movable side covers 2, which are rotatably connected to both sides of the furnace body 1, forming two independent heating stations between the two side covers 2 and the furnace body 1; a central heating unit 3, fixedly installed in the middle of the furnace body 1, with its two heating surfaces facing the two heating stations; and side heating units 4, which are respectively installed inside the two movable side covers 2, with their heating surfaces facing the two heating surfaces of the central heating unit 3 to form a heating area for heating workpieces within the heating station. The central heating unit 3 is a double-sided coated heating plate, with its two heating surfaces facing the two heating stations. The side heating units 4 include: single-sided coated heating plates 410, with their heating surfaces facing the heating surfaces of the central heating unit 3.

[0037] The main body 1 of the heating furnace is the basic support structure of the double heating furnace. Two movable side covers 2 are rotatably connected to both sides of the main body 1. The rotatable connection allows the movable side covers 2 to be opened and closed flexibly. The two movable side covers 2 and the main body 1 form two independent heating stations, providing space for heating the workpiece. The central heating unit 3 is fixedly installed in the middle of the main body 1. The central heating unit 3 is a double-sided coated heating plate. Its two heating surfaces face the two heating stations respectively. The two side heating units 4 are installed on the inner side of the two movable side covers 2 respectively. The single-sided coated heating plate 410 in the side heating unit 4 faces the heating surface of the central heating unit 3. In each heating station, one heating surface of the central heating unit 3 and the corresponding heating surface of the side heating unit 4 are arranged opposite to each other, thereby forming a heating area for heating the workpiece (such as heat shrink tubing) in the heating station. During operation, the central heating unit 3 and two side heating units 4 are activated simultaneously. The two heating surfaces of the central heating unit 3 release heat to both heating stations simultaneously, and the heating surfaces of the two side heating units 4 also release heat to their respective heating stations. The two heat-shrink tubing located in the two heating stations simultaneously receive heat from both the central heating unit 3 and the side heating units 4, thus achieving simultaneous heating. This dual-heating furnace can simultaneously heat two heat-shrink tubings in two heating areas. Compared to traditional furnaces that can only heat one workpiece at a time, it can process more workpieces in the same amount of time. For example, where heating two heat-shrink tubings previously required two separate processes, it can now be done simultaneously, significantly shortening the total heating time. This effectively improves the heating efficiency of the fiber optic fusion splicer, resulting in faster heating and ultimately increased overall work efficiency. In addition, the design of using a double-sided coated heating element as the central heating unit 3 and two single-sided coated heating elements as the side heating units 4 cleverly utilizes the characteristics of the heating elements. While meeting the requirement of heating two heat shrink tubings at the same time, it avoids the use of multiple high-power heating elements. Compared with the solution of using multiple double-sided heating elements or more heating elements, it effectively reduces power consumption.

[0038] The bottom of the movable side cover 2 is connected to the furnace body 1 via a hinge mechanism, and the top of the movable side cover 2 is provided with a magnetic locking mechanism to keep the movable side cover 2 fixed to the furnace body 1 when closed. The magnetic locking mechanism includes: a first magnetic element disposed on the top of the movable side cover 2, and a second magnetic element disposed on the furnace body 1 and magnetically engaged with the first magnetic element. When the first magnetic element is a magnet, the second magnetic element is a magnet or an iron adsorption block; when the second magnetic element is a magnet, the first magnetic element is a magnet or an iron adsorption block.

[0039] The bottom of the movable side cover 2 is connected to the furnace body 1 via a hinge mechanism. This hinge mechanism can be a hinge shaft, allowing the movable side cover 2 to rotate around it, enabling it to flexibly switch between open and closed states. This facilitates the placement or removal of workpieces (such as heat shrink tubing) from the heating station. A magnetic locking mechanism is used to fix the movable side cover 2 to the furnace body 1 when closed. This mechanism consists of a first magnetic attractor located at the top of the movable side cover 2 and a second magnetic attractor located on the furnace body 1 and magnetically engaging with the first magnetic attractor. When the first magnetic attractor is a magnet, the second magnetic attractor can be a magnet or an iron adsorption block. If the second magnetic attractor is a magnet, according to the principle of opposite poles attracting, when the movable side cover 2 is closed, the opposite magnetic poles of the first and second magnetic attractors attract each other, generating an adsorption force that firmly fixes the movable side cover 2 to the furnace body 1. If the second magnetic attractor is an iron adsorption block, the magnet attracts iron materials, achieving the same adsorption and fixing effect. Similarly, when the second magnetic element is a magnet, and the first magnetic element is a magnet or an iron adsorption block, the movable side cover 2 can also be fixed to the heating furnace body 1 in the closed state through magnetic attraction. The hinge mechanism makes the opening and closing of the movable side cover 2 very convenient. Operators only need to gently rotate the movable side cover 2 to put in and take out the workpiece, without complicated disassembly and installation processes, thus improving the convenience and efficiency of operation. The magnetic locking mechanism provides a reliable fixing effect when the movable side cover 2 is closed. During the heating process, good sealing can reduce heat loss, improve heating efficiency, and ensure temperature stability in the heating area. At the same time, stable fixing can prevent the movable side cover 2 from being accidentally opened during the heating process, ensuring the safety and stability of the heating process.

[0040] The side heating unit 4 further includes a heating element holder 420. A single-sided coated heating element 410 is installed on the side of the heating element holder 420 near the central heating unit 3. The bottom of the heating element holder 420 is rotatably connected to the lower inner side of the movable side cover 2 via a hinge mechanism. A tensioning member 5 is provided between the side of the heating element holder 420 away from the central heating unit 3 and the inner side of the movable side cover 2. The tensioning member 5 includes a compression spring, with both ends of the compression spring fixedly connected to the heating element holder 420 and the inner side of the movable side cover 2, respectively.

[0041] The single-sided coated heating element 410 in the side heating unit 4 is installed on the side of the heating element seat 420 near the central heating unit 3. The bottom of the heating element seat 420 is rotatably connected to the lower inner side of the movable side cover 2 through a hinge mechanism, so that the heating element seat 420 can rotate around the hinge point within a certain range, thereby driving the single-sided coated heating element 410 to adjust its position. A tensioning element 5 is provided between the side of the heating element seat 420 away from the central heating unit 3 and the inner side of the movable side cover 2. The tensioning element 5 can be a compression spring, and its two ends are fixedly connected to the heating element seat 420 and the inner side of the movable side cover 2, respectively. When the movable side cover 2 is in the closed state, the compression spring is in the compressed state, which generates an outward elastic force. The elastic force acts on the heating element seat 420, causing the heating element seat 420 to rotate around the hinge point towards the central heating unit 3, thereby allowing the single-sided coated heating element 410 to be more closely attached to the workpiece and ensuring the heating effect. When the movable side cover 2 is opened, the compression spring is released, and its elastic force decreases. Under the influence of its own weight and other factors, the heating element holder 420 may rotate slightly around the hinge point, increasing the distance between the single-sided coated heating element 410 and the central heating unit 3, making it easier to insert or remove the workpiece. The combined design of the hinge mechanism and the tensioning element 5 gives the side heating unit 4 a certain degree of flexibility and adaptability. During the frequent opening and closing of the movable side cover 2, the heating element holder 420 can adjust its position accordingly with the state of the movable side cover 2. At the same time, the elastic force of the compression spring can ensure the stability of the structure, reduce the positional displacement of the single-sided coated heating element 410 caused by vibration and other factors, and ensure the stable operation of the heating process.

[0042] The aforementioned dual-unit heating furnace further includes a temperature detection unit for detecting the resistance values ​​of the central heating unit 3 and the two side heating units 4. The temperature detection unit can use commercially available temperature sensors, detecting temperature by measuring changes in the resistance of the heating elements. It offers advantages such as accurate temperature measurement, no delay, and no need for additional components.
