Description

Technical Field

[0001] The present invention relates to the technical field of welding, and particularly to a microelectronic adjustable auxiliary welding device. Background Art

[0002] In the existing PCBA electronic component welding process, conventional operations mainly rely on two technical means: soldering iron welding and hot air gun soldering. In the welding scenario of conventional-sized components, the above processes have high applicability: for components with a relatively large volume, due to the relatively generous solder joint size and sufficient solder usage, operators can directly observe the solder wetting state and the welding interface morphology in the pad area by visual inspection, so as to effectively judge the welding quality. However, when it comes to microelectronic components, the existing technical system exposes significant technical defects.

[0003] The welding operation of micro-miniature electronic components faces multiple technical bottlenecks. First, the sharp reduction in the component package size leads to a geometric decrease in the pad contact area, which makes the resolution ability of traditional visual inspection means face physical limits. Second, in typical application scenarios where the PCB layout space is limited, designers often need to further compress the pad design size to meet the high-density integration requirements. The resulting pad-device size matching relationship doubles the difficulty of visual evaluation of welding quality.

[0004] The above technical defects directly lead to the systematic risk of welding process quality control: it is difficult for operators to accurately judge the metallurgical bonding state of the welding interface of micro-components, and potential defects such as virtual soldering and bridging are difficult to detect in a timely manner. This situation is particularly prominent in the field of precision electronic equipment manufacturing, and micro-welding defects may cause abnormal circuit functions or even systemic failures. Therefore, it can be seen that how to provide a device that can assist users in accurately seeing the welding situation of PCBA electronic components, so that users can accurately observe the welding situation and then ensure the welding quality has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0032] See Figures 1 - 3 , an adjustable microelectronic auxiliary welding device is proposed in the embodiments of the present invention. The adjustable microelectronic auxiliary welding device can assist the user to accurately see the welding situation of the workpiece to be welded 80 (such as PCBA), thereby ensuring the welding quality. To achieve the above technical objectives, the adjustable microelectronic auxiliary welding device includes a base 10, an angle adjustment mechanism 20, a welding table 30, a fixing mechanism 40, a magnifying glass 50, a flexible bracket 60, and a light source 70. The specific structure is introduced as follows:

[0033] The base 10 is connected to the welding table 30 through the angle adjustment mechanism 20. The tilt angle of the welding table 30 can be adjusted through the angle adjustment mechanism 20, so as to facilitate the user to adjust the viewing angle and accurately see the welding position.

[0034] The fixing mechanism 40 is arranged on the welding table 30 and is used to fix the workpiece to be welded 80; the workpiece to be welded 80 can specifically be the workpiece to be welded 80 (such as a PCBA), and the present invention does not specifically limit this. The fixing mechanism 40 can reliably fix the workpiece to be welded 80 and prevent it from shaking.

[0035] The magnifying glass 50 is arranged on the welding table 30 through the flexible bracket 60, and the light source 70 is arranged on one side of the welding table 30 and is used to provide illumination to the welding table 30. The magnifying glass 50 facilitates the user to observe the welding details, and the flexible bracket 60 can arbitrarily adjust the angle of the magnifying glass 50, facilitating the user to observe. The light source 70 can provide reliable illumination, enabling the user to clearly see the welding situation.

[0036] The microelectronic adjustable auxiliary welding device of the present invention realizes a systematic improvement in welding quality control through the coordinated action of multiple modules, and its technical effects are as follows:

[0037] Spatial positioning optimization: Through the linkage design of the angle adjustment mechanism 20 and the welding table 30, the operation plane has the ability to tilt in multiple directions, breaking through the spatial constraints of the traditional fixed welding table 30. This feature enables the welding area to dynamically match the best viewing angle of the human eye, effectively solving the solder joint positioning error caused by viewing angle deviation.

[0038] Enhanced observation accuracy: The combined innovation of the magnifying glass 50 component and the flexible bracket 60 endows the observation system with three-dimensional spatial freedom while maintaining the optical magnification function. The operator can accurately adjust the azimuth angle and pitch angle of the magnifying glass 50 according to the spatial distribution characteristics of the welding sites, significantly improving the identification ability of the micro-solder joint morphology.

[0039] Guaranteed operation stability: The multi-directionally adjustable characteristic of the fixing mechanism 40 forms an adaptive clamping force field, continuously offsetting the mechanical influence of external disturbances on the PCB board during the welding process. This mechanism maintains the planar stability of the workpiece to be welded 80 by dynamically balancing the acting forces during the assembly of components.

[0040] Improved lighting quality: The spatial coordination design of the light source 70 module and the welding table 30 forms a shadowless illumination optical path. This layout can eliminate the shadow shielding effect generated by traditional lateral illumination and ensure the uniformity of the illuminance distribution in the welding area.

[0041] The present invention fundamentally improves the controllability and reliability of microelectronic welding operations through the organic integration of mechanical structure innovation and optoelectronic system optimization, providing an effective technical solution for the field of high-density electronic assembly.
