Description

Technical Field

[0001] This utility model relates to the field of cable processing, and in particular to a hot soldering device for exposed ends of cables. Background Technology

[0002] During the process of processing cables into cable harnesses, after the cables are stripped, they need to be treated with a hot tinning process to form a tin film on the exposed end surface. This prevents the exposed wires from splitting after stripping. The tin film can also reduce the heat generated at the wire joints, avoid line faults and installation hazards, prevent wire oxidation, and improve the reliability of the cable harness.

[0003] Currently, the molten solder tray (with heating function) used in the hot soldering process is placed directly on the workbench, causing the molten solder level to be higher than the workbench surface. When workers are handling stripped cables for hot soldering, they have to raise their hands to operate, which is inefficient. In addition, an oxide film forms on the surface of the molten solder at high temperatures. After manually scraping the oxide film off the molten solder tray with the provided rake, it falls directly onto the workbench, which not only poses a risk of burns but also makes it difficult to collect and process.

[0004] Therefore, how to design a simple and easy-to-use hot soldering device is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a hot-soldering device for exposed cable ends. This device has a simple structure, low modification cost, can improve the hot-soldering efficiency of workers, and facilitates the collection of oxide film, ensuring the safety of operators.

[0006] The technical solution of this utility model is: a hot soldering device for exposed cable ends, including a workbench and a solder pan. The workbench has a through mounting hole, and the solder pan is placed in the mounting hole without extending beyond the top surface of the workbench. The edge of the solder pan has a space between it and the inner wall of the mounting hole. A collection trough is provided in the support of the workbench, located below the solder pan. One end of the collection trough is sealed, and the other end is open. The projection of the mounting hole is located inside the collection trough.

[0007] It also includes a mounting frame with legs, the legs of which are fixed to the bottom surface of the workbench, so that the mounting frame is suspended in the mounting holes of the workbench. The molten solder tray is supported on the mounting frame by its edge and is lower than the top surface of the workbench.

[0008] The molten solder tray is rectangular, the mounting frame is rectangular and the inner frame is adapted to the shape of the molten solder tray, the mounting hole is rectangular and there is a space between the two long sides of the molten solder tray and the inner wall corresponding to the mounting hole.

[0009] The collection tank extends along the length of the molten tin pan.

[0010] It also includes an inclined collecting plate, which is located below the space between the edge of the molten tin pan and the inner wall of the mounting hole. The lower edge of the inclined collecting plate is supported on one wall of the collecting tank, and the upper edge extends away from the collecting tank and is adhered to the bottom surface of the workbench by tape.

[0011] The workbench is supported by two crossbeams, and the collection trough is supported on the two crossbeams.

[0012] The above technical solution has the following beneficial effects:

[0013] 1. The tinning device for exposed cable ends includes a workbench and a molten solder tray. The workbench is used for assembling the molten solder tray and for placing the workpiece to be tinned. The molten solder tray holds molten solder and keeps it in a molten state so that the exposed end of the stripped cable can be immersed in it for tinning. The workbench has a through mounting hole, and the molten solder tray is placed in the mounting hole without exceeding the top surface of the workbench. That is, the molten solder level in the tray is always lower than the top surface (workbench surface) of the workbench. The operator can immerse the exposed end of the stripped cable below the liquid level for tinning without lifting their hand, which reduces manual labor intensity and the risk of molten solder splashing. The molten solder tray has a space between its rim and the inner wall of the assembly hole. When an oxide film forms on the surface of the molten solder in the tray, workers use a rake to remove the oxide film from the tray and separate it through the space between the tray and the assembly hole. This avoids the risk of burns caused by the oxide film falling onto the workbench and also prevents damage to the workbench from direct contact with the hot molten solder. A collection tank is installed in the workbench support below the molten solder tray. One end of the collection tank is sealed, and the other end is open. The projection of the assembly hole is located inside the collection tank. The solid oxide film separated from the space between the molten solder tray and the assembly hole falls into the collection tank and accumulates. Once a certain amount has been collected, the collection tank is moved, and the collected oxide film is discharged from the open end of the collection tank by tilting. This effectively meets the centralized processing needs of enterprises.

[0014] 2. It also includes a mounting frame with legs. The legs of the mounting frame are fixed to the bottom surface of the workbench, so that the mounting frame is suspended in the mounting holes of the workbench. The solder pan is supported on the mounting frame by its edge and is lower than the top surface of the workbench. The support of the solder pan on the mounting frame ensures the stability of the solder pan. In addition, the installation and removal of the solder pan are very convenient.

[0015] 3. It also includes an inclined collecting plate, which is located below the space between the edge of the molten tin pan and the inner wall of the assembly hole. The lower edge of the inclined collecting plate is supported on one wall of the collecting tank, and the upper edge extends away from the collecting tank and is adhered to the bottom surface of the workbench by tape. The inclined collecting plate has a simple installation structure and a simple and reliable installation method. The inclined collecting plate protects the legs of the workers, preventing individual separated oxide films from falling onto the workers' legs and causing burns. It also prevents the oxide film from scattering and facilitates centralized processing.

[0016] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the structure of this utility model;

[0018] Figure 2 for Figure 1 Sectional view along line AA.

[0019] In the attached diagram, 1 is the workbench, 11 is the platform, 12 is the support, 2 is the solder pan, 3 is the assembly hole, 4 is the collection tank, 5 is the mounting frame, 6 is the inclined collection plate, and 7 is the crossbeam. Detailed Implementation

[0020] See Figure 1 and Figure 2This is a specific embodiment of a hot-plating device for exposed cable ends. The hot-plating device for exposed cable ends includes a workbench 1 and a molten solder tray 2. The molten solder tray is a conventional molten solder tray with a heating function, used to melt molten tin and maintain it in a molten state. Specifically, the molten solder tray is rectangular. The workbench plate 11 is provided with a through mounting hole 3. The molten solder tray 2 is placed in the mounting hole 3 and does not extend beyond the top surface of the workbench plate 11. The edge of the molten solder tray 2 has a gap with the inner wall of the mounting hole 3. In this embodiment, the mounting hole on the workbench plate is a rectangular hole, and a mounting frame 5 is suspended in the rectangular hole. Obviously, the mounting frame 5 is a rectangular frame, and the inner frame is adapted to the shape of the molten solder tray 2. The four corners of the mounting frame are provided with feet. The support legs are fixed to the bottom surface of the workbench plate 11, allowing the mounting frame 5 to suspend in the workbench mounting hole 3. The solder molten plate 2 is supported on the mounting frame 5 by its edge and is lower than the top surface of the workbench plate 11. Typically, the two shorter sides of the mounting frame are wider than the two longer sides, causing the edge of the longer side of the solder molten plate to extend beyond the longer side of the mounting frame, while the edge of the shorter side does not extend beyond the shorter side of the mounting frame. This creates a gap between the two longer sides of the solder molten plate 2 and the inner wall corresponding to the mounting hole 3. A collection tank 4 is provided in the support 12 of the workbench, located below the solder molten plate 2. Specifically, two crossbeams 7 are provided on the support 12 of the workbench, and the collection tank 4 is supported on the two crossbeams 7. One end of the collection tank 4 is sealed and the other end is open. The projection of the assembly hole 3 is located inside the collection tank 4. In order to protect the workers, an inclined collection plate 6 is also provided. The inclined collection plate 6 is located below the space between the edge of the molten solder pan and the inner wall of the assembly hole. The lower edge of the inclined collection plate 6 is supported on one wall of the collection tank 4, and the upper edge extends away from the collection tank 4 and is adhered to the bottom surface of the workbench 11 by tape.

[0021] The working principle of this invention is as follows: The worker sits beside a long side of the workbench, corresponding to the long side of the molten solder tray. The stripped cable rests on one side of the workbench. The worker picks up the stripped cable and, without lifting their hand, immerses the exposed end of the cable below the molten solder level for soldering. After soldering, the exposed end of the cable is immersed in a cup of cold water to cool it down, completing the soldering process. When an oxide film forms on the surface of the molten solder in the tray, the worker uses a rake to remove the oxide film from the tray and separate it through the gap between the tray and the assembly hole, allowing it to fall into a collection tank below. A tilted collection plate prevents individual pieces of oxide film from falling onto the worker's legs and causing burns. Once a certain amount of oxide film has been collected in the collection tank, the tank is moved, and the collected oxide film is discharged from the opening of the collection tank by tilting.
