Description

TECHNICAL FIELD

[0001] The utility model relates to continuous push and pull force test tool technical field, more specifically, relate to a kind of continuous push and pull force test tool applied to fin welding point. BACKGROUND

[0002] During the operation of electronic equipment, various electronic components will continuously generate a large amount of heat, which will cause the internal temperature of the equipment to rise sharply if it cannot be effectively dissipated in time. High temperature will seriously interfere with the normal operation of electronic components, cause signal transmission abnormalities, operation accuracy decline and other problems, and over time, it will also accelerate the aging of electronic components and greatly shorten the service life of the equipment. The main working principle of the heat sink is to rapidly conduct and diffuse the heat generated by the electronic components to the surrounding environment through its large-area metal structure. The welding quality between the heat sink and the product is a key factor in determining the heat conduction efficiency. Poor welding quality, such as virtual welding, delamination or insufficient welding strength, will form a large thermal resistance between the heat sink and the product, hindering the smooth transfer of heat, and thus greatly reducing the heat dissipation effect. Once the heat dissipation effect cannot meet the equipment operation requirements, the internal temperature of the equipment will continue to be too high, which will not only affect the current work performance, but also pose a serious threat to the long-term stability and reliability of the equipment, greatly shortening the service life of the equipment.

Manual visual inspection is highly subjective and has large errors, and it is difficult to detect small welding defects and potential mechanical properties. Simple physical measurement can only obtain static data and cannot simulate the dynamic tension that the welding point bears in actual use.

[0005] The utility model can stably apply and real-time monitor tension through the cooperation of pull rod, transmission lever, tension meter and motor, meet the continuous push and pull force test of fin welding point, and guarantee the welding quality of product. UTILITY MODEL CONTENTS
