Referring to fig. 1 and 5, according to the laminator of the embodiment of the present invention, the roller structure of the laminator comprises: a frame (not shown), a conveyor assembly 10 and a roller assembly 20; the transfer assembly 10 is disposed on the chassis, and the transfer assembly 10 may transfer the PCB circuit board. Roll subassembly 20 sets up in the frame and is located one side of transfer module 10 to receive the PCB circuit board, roll subassembly 20 includes and presses roll 21 and press roll 22 down, and the both ends of pressing roll 21 and pressing roll 22 down on are wrapped up in and are covered protective layer 23, go up and have first clearance between the protective layer 23 on pressing roll 21 and pressing roll 22 down, and first clearance can hold the both sides limit of PCB circuit board and pass through.

The transfer assembly 10 transfers the PCB circuit board, which is attached with the dry film, to the roller assembly 20. The upper roller 21 and the lower roller 22 in the roller assembly 20 paste the dry film on the PCB. Meanwhile, the both ends of going up pressure rumble 21 and pressing rumble 22 down all wrap up in and have covered one deck protective layer 23, the both sides limit of PCB circuit board is between protective layer 23, protective layer 23 can play the effect of pressing rumble 21 and pressing rumble 22 down on the protection, avoid burr on the PCB circuit board both sides limit, sawtooth etc. and last pressure rumble 21 and the surperficial direct contact who presses rumble 22 down, thereby alleviate the PCB circuit board and to last pressure rumble 21 and the loss of pressing rumble 22 down, and then improve the life of sticking film machine.

Referring to fig. 1 and 2, in some embodiments of the present invention, the protective layer 23 mentioned in the above embodiments may be a common adhesive tape, that is, an adhesive tape wound around two ends of the upper roller 21 and the lower roller 22 for one or more turns, and the adhesive tape should not be wound too much, so as to prevent the PCB from passing through the first gap too small between the upper roller 21 and the lower roller 22. It is therefore contemplated that when the PCB passes through the first gap, the wrapping of the tape prevents burrs, saw teeth, etc. on the two sides of the PCB from directly contacting the surfaces of the upper roller 21 and the lower roller 22, and the upper roller 21 and the lower roller 22 are directly protected, thereby reducing damage to the roller assembly 20 caused by the burrs or saw teeth.

In some embodiments of the present invention, the upper and

lower rollers

21 and 22 may be provided with heating devices, and the heating devices may be used for heating the upper and

lower rollers

21 and 22. The sticking film machine is used for the dry film of PCB circuit board, will press rumble 21 and press rumble 22 heating down on among the rumble subassembly 20, pass on the PCB circuit board and press rumble 21 and press down the first clearance between the rumble 22, the last rumble 21 and press rumble 22 down of heating can heat and pressurize the PCB circuit board, thereby can hug closely the dry film on the surface of PCB circuit board, the last rumble 21 and the rumble 22 of pressing down after the heating can more do benefit to the dry film and hug closely on PCB circuit board. It should be emphasized that the heating devices in the upper and

lower rollers

21 and 22 may be heating wires, heating pipes, or even high temperature gas or liquid, etc., so the present invention does not specifically limit the structure of the heating devices, and can meet the heating requirements of the upper and

lower rollers

21 and 22.

It should be noted that, since the protective layer 23 is provided on the upper roller 21 and the lower roller 22, the protective layer 23 also has a high temperature resistance property, and the upper roller 21 and the lower roller 22 in a high temperature state are prevented from damaging the protective layer 23 and losing its protective effect.

In some embodiments of the utility model, a rubber layer may also be provided over the upper and

lower rollers

21, 22. The rubber is a high-elasticity polymer material with reversible deformation, is rich in elasticity at room temperature, can generate large deformation under the action of small external force, and can recover the original shape after the external force is removed. So be rich in elasticity and can prevent to press rumble 21 and press rumble 22 down and crush PCB circuit board, reversible deformation's characteristics are more fit for pressing rumble 21 and press rumble 22 down and continue the work of pasting the dry film.

Referring to fig. 1 to 3, in some embodiments of the present invention, the transmission gear 25 is provided at both ends of the upper and

lower rumbles
