[0002] Potting is the process of mechanically or manually pouring liquid polyurethane compounds into devices containing electronic components and circuits, and curing them at room temperature or under heating conditions to become thermosetting polymer insulating materials with excellent performance.

[0003] When applying for the present invention, the applicant found through searching that a Chinese patent disclosed a "pressing machine for potting glue", and its application number is "CN208867415U". This patent mainly rotates a rotating handle, which drives the spiral rod to rotate and move downward at the same time. Since the spiral rod and the pressure rod are movably connected, the pressure rod and the spiral rod can rotate relative to each other, thereby moving the pressure rod downward. However, the process of rotating the handle is time-consuming, labor-intensive, and inefficient. The buzzer sends an alarm to remind the user to stop rotating, which requires a certain reaction time and may cause damage to electronic components. Utility Model Content
