Description

Technical Field

[0001] This utility model relates to the field of optical communication module processing technology, specifically to a high-efficiency cable welding fixture. Background Technology

[0002] SFP DAC high-speed cables are widely used in short-distance, high-speed interconnect scenarios such as data centers due to their low cost and low power consumption. Soldering the cable cores to the circuit board (PCB) is one of the key processes in their production.

[0003] Currently, this welding process mainly relies on manual operation: workers use tools such as tweezers to manually align the thin core wires with tiny solder joints on the circuit board before welding. This traditional manual method has many drawbacks: First, the cables themselves are relatively flexible and difficult to position precisely, causing the alignment accuracy between the core wire and the solder joint to depend entirely on the worker's experience and skill, resulting in poor product consistency; second, the alignment process is time-consuming and labor-intensive, leading to low production efficiency; third, because alignment accuracy is difficult to guarantee, short circuits, open circuits, and other defects are prone to occur after welding, resulting in a low product pass rate. Therefore, there is an urgent need for an automated solution that can improve welding efficiency and accuracy. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a high-efficiency cable welding fixture, which aims to solve the problems of inaccurate positioning, low efficiency and poor product consistency in the existing SFP DAC cable welding process.

[0005] This utility model is achieved through the following technical solution: A high-efficiency cable welding fixture, comprising: The injection positioning fixture is used to fix the ends of multiple cables in parallel and to form a positioning block with a uniform positioning reference at the cable ends by injection molding. Welding fixture, which is equipped with: The positioning part, whose structure matches the shape of the positioning rubber block, is used to accommodate and fix the cable with the positioning rubber block. Circuit board support section, used to hold the circuit board to be soldered; The positioning part and the circuit board support part have a preset relative positional relationship on the welding fixture. When the positioning block and the circuit board are placed on the positioning part and the circuit board support part respectively, the end of the core wire of the cable is precisely aligned with the solder joint of the circuit board.

[0006] It also includes a core wire sorting fixture, which is provided with a comb-like structure or guide groove for separating and constraining each core wire.

[0007] The glue injection positioning fixture includes multiple cable receiving slots arranged side by side.

[0008] The positioning part of the welding fixture is a groove structure that matches the shape of the positioning rubber block.

[0009] The welding fixture is equipped with multiple sets of positioning parts and circuit board support parts arranged side by side, which are used to complete the simultaneous clamping and welding of multiple products at one time.

[0010] The circuit board bearing portion of the welding fixture is provided with a limiting structure for defining the position of the circuit board.

[0011] The beneficial effects of this utility model are: This utility model discloses a high-efficiency cable welding fixture, which, by setting up an injection positioning clamp and a welding clamp, allows for the simultaneous injection and molding of multiple cables. Utilizing a welding clamp capable of supporting multiple product sets, it enables batch synchronous welding, significantly increasing production efficiency. It completely eliminates human error, ensuring highly consistent welding precision for each product and significantly improving product quality and reliability. Furthermore, precise alignment effectively avoids defects such as short circuits and incomplete welds caused by misalignment, thereby greatly increasing the first-pass yield. It simplifies the complex alignment process into a simple placement action, which can be operated by ordinary workers, reducing labor and training costs for enterprises. Attached Figure Description

[0015] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0018] like Figure 1 As shown, this embodiment discloses a high-efficiency cable welding fixture, which includes: The injection positioning fixture is used to fix the ends of multiple cables in parallel and to form a positioning block with a uniform positioning reference at the cable ends by injection molding. Welding fixture, which is equipped with: The positioning part 201 has a structure that matches the shape of the positioning rubber block and is used to accommodate and fix the cable with the positioning rubber block. The circuit board support 202 is used to hold the circuit board to be soldered; The positioning part 201 and the circuit board support part 202 have a preset relative positional relationship on the welding fixture. When the positioning block and the circuit board are placed on the positioning part 201 and the circuit board support part 202 respectively, the end of the core wire of the cable is precisely aligned with the solder joint of the circuit board.

[0019] Furthermore, the high-efficiency cable welding fixture also includes a core wire sorting fixture (not shown in the figure), which is provided with a comb-like structure or guide groove for separating and constraining each core wire.

[0020] Furthermore, the glue injection positioning fixture includes a plurality of cable receiving slots 101 arranged side by side.

[0021] Furthermore, the positioning part 201 of the welding fixture is a groove structure that is adapted to the shape of the positioning rubber block.

[0022] Furthermore, the welding fixture is provided with multiple sets of positioning parts 201 and circuit board support parts 202 arranged side by side, for simultaneously clamping and welding multiple products at one time.

[0023] Furthermore, the circuit board support portion 202 of the welding fixture is provided with a limiting structure 203 for limiting the position of the circuit board.

[0024] Before using the efficient cable welding fixture of this embodiment, it is necessary to first organize the multiple core wires exposed after stripping the outer sheath. For this purpose, a separate core wire organizing fixture can be used, which is equipped with a comb-like structure or a series of precision guide grooves. By passing the messy core wire bundle through the structure, each core wire can be separated and arranged neatly according to a preset spacing and order.

[0025] After the core wires are arranged, the injection positioning fixture of this invention is used. This fixture has multiple parallel cable receiving slots 101 for parallel fixing of the main body portions of multiple cables. The arranged core wire ends are then introduced into the mold cavity of the fixture. Subsequently, molten plastic (such as ABS, PC, etc.) is injected into the mold cavity using an injection molding machine. After the plastic cools and solidifies, it collectively wraps around the ends of the multiple cables to form a rigid positioning block. The shape of this positioning block is determined by the shape of the mold cavity, possessing uniform and precise dimensions and shape, and its surface can serve as a unified positioning reference for all subsequent processes.

[0026] Since the welding fixture and the glue injection positioning fixture are on the same jig, the cable assembly can be welded immediately after the glue injection positioning fixture is filled with glue in the glue injection positioning fixture.

[0027] The welding fixture is key to achieving the final precise alignment. It is equipped with a positioning part 201, which is preferably a groove structure that perfectly matches the shape of the positioning rubber block; at the same time, the fixture is also equipped with a circuit board support part 202, which may be equipped with positioning pins, stops and other limiting structures 203 for precise positioning of the circuit board to be welded.

[0028] The relative spatial positions of the positioning part 201 and the circuit board carrier part 202 on the welding fixture are precisely designed and manufactured, and remain fixed.

[0029] The operation requires only two simple actions: The cable assembly with the positioning rubber block is placed into the positioning part 201. The tight fit between the positioning rubber block and the groove ensures that the position of the cable assembly is precisely locked.

[0030] The circuit board to be soldered is placed on the circuit board support 202 and positioned by the limiting structure 203.

[0031] Once both components are in place, due to the precise positioning of the fixture, the ends of all the core wires will automatically and accurately align with the corresponding solder points on the circuit board, without any additional adjustments. At this point, the soldering of all solder points can be quickly completed using methods such as thermoforming, laser soldering, or drag soldering.

[0032] To meet the demands of mass production, multiple sets (e.g., 6 sets) of identical positioning parts 201 and circuit board support parts 202 can be integrated side-by-side on the welding fixture. In this way, multiple products can be positioned synchronously in a single clamping action, and when combined with appropriate batch welding equipment, production efficiency can be multiplied.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
