Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to an automatic hot riveting machine for thermal protector blade assemblies. Background Technology

[0002] Thermal protectors are critical circuit protection components widely used in overcurrent and overheat protection for household appliances, motors, and various electronic products. The thermal protector blade assembly, as a core component, directly affects the thermal protector's conductivity, response speed, and lifespan through its assembly quality.

[0003] Currently, the hot riveting assembly of thermal protector blade assemblies is mainly completed manually or with semi-automated equipment. Existing technologies generally suffer from the following drawbacks: In manual hot riveting, workers must use hand-held heating tools to melt the positioning pins. Since temperature and holding time are controlled manually based on experience, problems such as incomplete or excessive melting are prone to occur, causing the iron blade to loosen on the plastic part, affecting the electrical conductivity and reliability of the thermal protector during operation. Excessive heating time or temperature can damage the riveting points or even render the entire plastic part unusable. Due to the small size of the thermal protector blade assemblies, manual operation is difficult, making alignment accuracy hard to guarantee, and single-piece assembly time long, resulting in low production efficiency. Even with partially automated equipment, the assembly of thermal protector components still heavily relies on manual feeding and hot riveting. Long-term operation can easily lead to worker fatigue and burn risks, and it is also difficult to meet the capacity and delivery cycle requirements of large-scale production.
