Description

Technical Field

[0001] The present application relates to the technical field of diode repair equipment, and in particular to a composite diode welding auxiliary tool. Background Art

[0002] The statements in this section merely provide background technical information related to the present application and do not necessarily constitute prior art.

[0003] At present, the welding of electronic components on circuit boards has basically been realized in batches and automation, without manual operation, but this belongs to the production link. After the processed and assembled circuit boards are put into use, it is inevitable that the electronic components on the circuit boards will be damaged during use, such as overcurrent, short circuit caused by conductive dust, loose solder joints caused by heat, etc., which will affect the life of the electronic components on the circuit boards.

[0004] If an electronic component on a circuit board is damaged, replacing the entire circuit board will undoubtedly increase costs and waste resources. Manufacturing companies often find some repair shops to repair circuit boards. Circuit boards can only be repaired manually after manual inspection and determination of the faulty components. Among them, composite diodes are commonly used electronic components, and their failure frequency is also high. Since some composite diodes are very small in size and difficult to pick up manually, workers often use tweezers to clamp them and then weld them. However, this has disadvantages: it is unstable to clamp composite diodes with tweezers manually. When welding, the left hand holds the tweezers and the right hand welds. Due to the small size, the left hand cannot hold it steadily, and welding cannot be guaranteed. On the other hand, clamping with tweezers requires manual application of a certain amount of pressure on the tweezers, and the pressure applied during welding cannot be guaranteed manually.

[0005] In view of this, it is necessary to provide a composite diode welding auxiliary tool to solve the above technical problems. Summary of the invention
