[0029] Working principle: When a film laminating device for circuit board production is in use, in the initial state, first, the feeding belt 101 is arranged on the upper surface of the film laminating equipment main body 1. A film roller 201 is installed on the support frame 2 arranged at the end of the upper surface of the film laminating equipment main body 1. A guide rod 202, a first rubber roller 203, and a second rubber roller 204 are also installed at a position near the bottom inside the support frame 2. At the same time, one end of the insulating film roll installed on the film roller 201 bypasses the guide rod 202 and adheres to the first rubber roller 203 and the second rubber roller 204 on the back. A dust removal mechanism 3 is arranged on the upper surface of the film laminating equipment main body 1 in front of the support frame 2, so that the circuit board after dust removal by the dust removal mechanism 3 can come into contact with the insulating film when passing under the second rubber roller 204 to complete bonding.

[0030] When dust removal is required for the circuit board, first, the feeding belt 101 is started by using the control button 102, and the circuit board is placed on the feeding belt 101.

At the same time when the circuit board contacts the pressure roller 310, the driving machine 304 controls the waste roller 303 to rotate to traction the dust removal tape on the storage roller 302 to move. Since the dust sticking surface of the dust sticking tape on the storage roller 302 bypasses from under the pressure roller 310, when the circuit board passes under the pressure roller 310, the pressure roller 310 will press the moving dust sticking tape to remove dust from the surface of the circuit board to be film laminated. This device is convenient for dust removal of the circuit board.
