Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and more specifically, to a welding device. Background Technology

[0002] In today's highly integrated and precision electronic equipment manufacturing industry, PCBs (Printed Circuit Boards) serve as the core carrier of electronic devices, and the precision of their manufacturing technology directly determines the performance and reliability of electronic products. With the rapid development of 5G, the Internet of Things, aerospace, and other fields, higher demands are placed on the signal transmission quality of PCBs, especially in high-frequency signal transmission. Coaxial cables have become the preferred connection method due to their advantages such as low loss, high bandwidth, and high anti-interference capability. The connection between the coaxial cable and the PCB, especially the soldering of the core wires to one side of the PCB and the soldering of the braided layer to the other side of the PCB, is crucial for the stability and integrity of the signal.

[0003] In current PCB board and coaxial cable soldering processes, especially double-sided soldering, manual soldering is the primary method. While this manual method offers some flexibility, it has revealed numerous problems in large-scale production:

[0004] (1) Low efficiency: Manual welding has limited capacity. Each solder joint requires careful alignment and welding by the operator. In particular, the welding of small coaxial core wires to PCB pads is difficult and time-consuming, which seriously restricts production efficiency.

[0005] (2) Unstable welding quality: Welding quality is greatly affected by the operator's skill and stability. Especially for welding that requires high precision, such as welding coaxial core wire to PCB pad, the operator may find it difficult to maintain consistent welding quality, resulting in a high welding defect rate.

[0006] (3) Safety risks: During manual soldering, the operator comes into direct contact with the high-temperature soldering iron tip, which can easily cause safety problems such as burns.

[0007] (4) Cost issues: Labor costs are high, especially for high-precision welding, which requires skilled technicians, further increasing production costs.

[0008] (5) Compatibility issues: Manual soldering is difficult to efficiently meet the soldering requirements of coaxial cables of different sizes and wire diameters to PCB boards. Operators need to frequently adjust tools, which reduces production flexibility.

[0009] (6) Subsequent inspection issues: The soldered PCB board needs to be manually inspected and tested for electrical properties to ensure the quality of the soldering. This not only increases the workload, but also makes it difficult to guarantee the accuracy and consistency of manual inspection.

[0010] Currently, while some automated PCB soldering equipment exists on the market, it primarily targets single-sided soldering or non-coaxial soldering. For PCBs requiring double-sided soldering, especially when soldering the core wires and braided layers on different sides, these devices often struggle to meet the demands for precise positioning and efficient soldering. This is particularly true for PTFE PCBs, where the material's softness, small core wire size, and inconsistent pad sizes on both sides of the PCB make the core wires prone to breakage during flipping and soldering. These issues further exacerbate the complexity and challenge of manual soldering. To date, no mature technology or equipment has emerged that effectively solves the problem of automated double-sided PCB soldering, especially for soldering coaxial cables of different diameters and lengths to PCBs. This has become a bottleneck restricting the efficient and high-quality production of PCBs.

[0011] In summary, the current PCB board and coaxial cable welding methods have a low degree of automation and cannot meet the requirements of high production capacity and high quality in modern electronic manufacturing. Utility Model Content
