[0001] The utility model relates to plastic package mould cleaning technical field, concretely is a plastic package mould opening mould trigger automatic cleaning device and system. BACKGROUND

[0002] In the field of electronic device manufacturing, frame bridge stack as a kind of key integrated rectifier, bears the important task of converting alternating current into direct current in various power supply circuits. With the rapid development of electronic technology, the demand for frame bridge stack is growing, and its packaging technology is continuously innovating. Plastic package mould plays a pivotal role in frame bridge stack packaging, especially now, multi-injection head plastic package mould gradually replaces traditional single cylinder mould with its efficiency, and the mould size is developing towards large-scale to meet the increasing demand for product quality and yield. Plastic packaging process has very high requirements for environmental cleanliness. After each plastic packaging operation is completed, the mould parting surface will inevitably leave plastic packaging waste and other impurities. These seemingly small residual substances, if not removed in time, will cause a series of serious problems in the subsequent packaging process. They may damage the strip and chip circuit under pressure, causing circuit short circuit or open circuit failure; It may also cause overflow, affecting the appearance and performance of the packaged product; More seriously, long-term accumulation of impurities may damage the plastic package mould, increase equipment maintenance cost, reduce production efficiency, and pose a serious threat to the stability of the entire plastic packaging process and product quality. Currently, the cleaning work after the plastic package mould is opened mostly relies on manual operation. The staff needs to wear gloves and manually remove the larger plastic waste on the surface of the mould, and then use an air gun to blow off the remaining small waste. However, this traditional cleaning method has many drawbacks. From the safety point of view, the surface temperature of the plastic package mould is high when it is opened, and even if the staff wears gloves, there is still a risk of burns during manual operation. At the same time, when using an air gun to blow, the high-speed airflow may blow the waste to the eyes, skin and other parts of the staff, causing accidental injury and posing a great safety hazard.

[0003] To solve the above-mentioned manual cleaning problem, the industry tries to install a cleaning roller on the plastic packaging machine and cooperate with a jet device, which rotates the brush roller to clean the dust and plastic on the upper and lower moulds, and at the same time uses a fan to generate negative pressure to make the air flow, so as to realize the purpose of cleaning. However, different plastic package moulds have different effective sizes, and the effective cleaning position of the brush roller in the existing cleaning device cannot be flexibly adjusted, resulting in that some special size moulds cannot be effectively cleaned, the cleaning effect cannot be guaranteed, and the diversified mould cleaning demand cannot be met.
