It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1 to 2, the present invention provides a sealing laminator 100, which includes a conveying device 10, a dry film feeding device 20, a sealing pressing device 30 and a cutting device 40.

The sealing and pressing device 30 includes a bearing base 31, a pressing cylinder 32, a pneumatic tube 33 and a lifting rod 34. The carrying base 31 is installed in the conveying device 10, the lifting rod 34 and the pressing cylinder 32 are both suspended right above the carrying base 31, the pressing cylinder 32 is installed at the lower end of the lifting rod 34, and the pneumatic tube 33 is installed at one side of the pressing cylinder 32 and communicated with the pressing cylinder 32. The upper end of the bearing base 31 is provided with a plurality of negative pressure suckers 35. The pressing cylinder 32 can be pushed by the lifting rod 34 to be attached to the bearing base 31 to form a closed cavity, so that the film pressing machine can press the PCB on the bearing base 31 in an air pressure mode, and the dry film is completely attached to the surface of the PCB. The pneumatic tube 33 arranged on one side of the pressing cylinder 32 avoids the possibility that the dry film and even the PCB are damaged due to the fact that high-pressure air in the pneumatic tube 33 is directly sprayed on the dry film. And bear the weight of the vacuum chuck 35 on the base 31 and can firmly adsorb PCB, make it keep firm not rocking at the press mold in-process, further promoted the press mold quality.

The conveying device 10 includes a conveying frame 11, a conveying roller 12 and a conveying belt 13. The conveying rollers 12 are arranged at two ends of the conveying frame 11, and the conveying belt 13 is sleeved on the conveying frame 11 and the conveying rollers 12. The conveyor belt 13 is designed to be hollow and made of a material with good elasticity. The width of the conveying frame 11 is larger than that of the stitching air cylinder 32, and the widths of the conveying roller 12 and the conveying belt 13 are larger than or equal to that of the stitching air cylinder 32. The hollow-out conveyor belt 13 prevents the negative pressure suction cup 35 on the bearing base 31 from adsorbing and stabilizing the PCB, and the good elasticity of the conveyor belt 13 is more convenient for the laminating cylinder 32 and the bearing base 31 to be attached to form a closed laminating cavity.

The dry film feeding device 20 is disposed between the conveying device 10 and the pressing cylinder 32, and the stroke direction of the dry film feeding device is perpendicular to the stroke direction of the conveying device 10. The dry film supply device 20 comprises an output end 21 and a receiving end 22 which are symmetrically designed, wherein the output end 21 and the receiving end 22 both comprise a support frame 23 and a winding roller 24.

At the same time, the dry film feeding device 20 starts to work to suspend the dry film above the supporting base 31. Then, the lifting rod 34 drives the pressing cylinder 32 to descend until a sealed pressing cavity is completely formed with the bearing base 31, the pneumatic tube 33 delivers high-pressure air into the pressing cylinder 32, and under the action of high pressure, the dry film inside the pressing cylinder 32 is tightly attached to the PCB. Then, the lifting arm 42 drives the cutting blade 43 to press down, so as to cut off the redundant dry film on the edge of the PCB. Finally, the lifting rod 34 drives the pressing cylinder 32 to ascend again, and the conveying device 10 continues to work to convey the PCB with film pressing completed to the subsequent station.
