Description

Technical Field

[0001] The invention relates to the technical field of semiconductor triode production, in particular to a welding device for semiconductor triode production. Background Art

[0002] The full name of the transistor should be semiconductor transistor, also known as bipolar transistor, crystal transistor, which is a semiconductor device that controls current. Its function is to amplify weak signals into electrical signals with larger amplitude values. It is also used as a contactless switch. The transistor is one of the basic semiconductor components, has the function of current amplification, and is the core component of electronic circuits. The transistor is made of two PN junctions very close to each other on a semiconductor substrate. The two PN junctions divide the entire semiconductor into three parts. The middle part is the base area, and the two sides are the emitter area and the collector area. There are two arrangements: PNP and NPN.

[0003] According to the patent application number CN202020335572.6, the utility model combines the pad and the placement plate by bolts, which is convenient for the overall disassembly and assembly of the base and the maintenance of the clamping assembly inside the base block. The clamping assembly is composed of a clamping plate and a spring, and the elastic deformation of the spring is utilized so that the two clamping plates can adaptively clamp the transistor housings of different models. While improving the positioning stability of the transistor housing, it is also convenient for subsequent welding operations on transistors of different models, thereby improving practicality.

[0004] In the above patent, the transistor is limited and fixed by a clamping assembly before welding. When welding other surfaces of the transistor, personnel are required to frequently adjust the clamping surface of the transistor to meet the welding requirements of different positions. Manual adjustment is time-consuming and labor-intensive, and manual unloading is required, which reduces the production efficiency of semiconductor transistors. Therefore, in view of the above shortcomings, the present invention makes the following improvements. Summary of the invention
