Problems solved by technology
In addition, the semiconductor production process is completed in the ultra-clean workshop, and the cleaning of the material box is also a task that must be carried out every day. It will also take a lot of time and money to clean a large number of material boxes. The labor load is large and the use cost higher
And if one of the material boxes is contaminated, it may affect the quality of the entire product. In severe cases, the product will be scrapped and the production cost will be increased;

Embodiment Construction
[0023] In the traditional plastic-encapsulated IPM production process, lead frames between different processes are collected and transported through material boxes, and the amount of material boxes is relatively large. Moreover, it takes a lot of time and money to clean a large number of material boxes. There is a large amount of labor, low work efficiency, high cost of use, and once the material box is not cleaned, it is easy to cause product pollution, resulting in a decline in product quality or even scrapping.
[0024] The present invention aims at the deficiencies in the prior art. The present invention provides a plastic-encapsulated IPM delivery system to realize the effective delivery of IPM between different processes, avoid the use of material boxes, reduce manual operation steps, reduce workload, and improve Improve work efficiency, reduce use cost, avoid product pollution, improve product quality and reduce production cost.
[0025] The technical solutions of the p...

The invention discloses a plastic package intelligent power module (IPM) conveying system. The plastic package IPM conveying system comprises a conveying track and a delivery mechanism which is located on the conveying track, and the conveying track is spliced by a left track and a right track. By means of the conveying track and the delivery mechanism, a plastic package IPM can be conveyed from last process to next process, a material box is omitted, workload can be reduced, the automation degree of a whole production line can be increased, the producing efficiency of the plastic package IPM is increased, the step of cleaning the material box is omitted, problems of product qualities caused by contamination of the material box can be avoided, production and usage costs are saved, meanwhile, the left track and the right track are spliced to form the conveying track so that the width of the whole conveying track can be adjusted, the conveying system is suitable for conveying products in different sizes, and the application range is wide.
Description
technical field [0001] The invention relates to the technical field of plastic-encapsulated IPM production, in particular to a plastic-encapsulated IPM delivery system. Background technique [0002] Plastic-encapsulated IPM (Intelligent Power Module, Intelligent Power Module) is a new type of control module that integrates the IGBT chip and its drive circuit, control circuit and overcurrent, undervoltage, short circuit, overheating and other protection circuits. It is a complex and advanced power module that can automatically realize complex protection functions such as overcurrent, undervoltage, short circuit and overheating, so it has intelligent features. At the same time, it has the advantages of low cost, miniaturization, high reliability, and easy use. It is widely used in frequency conversion home appliances, inverter power supplies, industrial control and other fields, and its social and economic benefits are considerable. [0003] For different plastic-encapsulated...
