[0035] S3: Vacuuming: Use the vacuuming device on the control panel to perform vacuuming on the sealing box for 9-11 minutes.

[0037] S5: Setting: After sealing, hold for 19-21 minutes to set;

[0040] S8: Output: After cooling is complete, the cylinder is depressurized via the control panel, and the sealed circuit board is conveyed to the discharge port.
[0041] The working principle of this invention is as follows: A continuous vacuum protective film encapsulation device is used to encapsulate the protective film of the intelligent bed frame circuit control board. The production process is modularized, integrating multiple individual steps. The carrier board or a flexible circuit board pre-applied with dry film is conveyed from the inlet to the vacuum section cavity through a PET film. At this time, the lower heating plate in the vacuum cavity rises and closely adheres to the upper heating plate, forming a sealed space. Then, the vacuum pump attached to the equipment evacuates the sealed space. After the vacuum level reaches the set value, pressurization begins, and heating is carried out simultaneously. When the pressurization time reaches the set value, the lower heating plate descends, and the board is conveyed to the outlet through the PET film again, completing one cycle. This process is repeated continuously.
