A pressing assembly is mounted on the other side of the lower end face of the horizontal section of the U-shaped frame 2, and a cutting assembly is mounted on one side of the pressing assembly.

[0020] The winding mechanism includes a servo motor 11 fixed to the bottom of one side of the L-shaped vertical plate 4. The vertical section of the servo motor 11 extends to the other side of the L-shaped vertical plate 4 and is connected to a turntable 21. A first support rod 22 is provided on one side of the turntable 21. An external thread 24 is provided at one end of the first support rod 22. A nut 19 is screwed onto the external thread 24. A clamping plate 23 is fitted on one side of the nut 19 and outside the external thread 24.

[0021] The unwinding mechanism includes a second support rod 5 fixed to one side of the top of the L-shaped vertical plate 4. A crossbar 6 is provided on the other side of the top of the L-shaped vertical plate 4. Two T-shaped rods 3 are symmetrically inserted on the crossbar 6. One end of the two T-shaped rods 3 is connected to a first U-shaped plate 10. The two ends of the first U-shaped plate 10 are rotatably mounted with extrusion rollers 8 through bearings. Springs 9 are fitted on the two T-shaped rods 3 at the part located between the first U-shaped plate 10 and the crossbar 6.

[0022] The clamping assembly includes two first electric push rods 13 fixed to the lower end face of the horizontal section of the U-shaped frame 2. The lower ends of the two first electric push rods 13 are connected to a second U-shaped plate 12. The two ends of the second U-shaped plate 12 are rotatably mounted with pressing rollers 15 through bearings. The pressing rollers 15 are located on the outside of the support plate 16.

[0023] The cutting assembly includes two second electric push rods 18 fixed to the lower end face of the horizontal section of the U-shaped frame 2.

The extrusion roller 8 is released, and under the rebound action of the spring 9, the extrusion roller 8 presses on the reflective film roll, pulling out a part of the reflective film, and the reflective film backing paper is wrapped around the peeling plate 7 and fixedly connected to the take-up shaft. The substrate to be laminated is placed in the limiting placement groove 25 of the conveyor belt 1, and the substrate is transported by the conveyor belt 1. When the substrate moves to below the tray 16, the substrate is further... The servo motor 11 drives the turntable 21, the first support rod 22, and the winding shaft to rotate. The winding shaft winds up the backing paper and pulls the backing paper to move, so that the reflective film is peeled off from the backing paper at the end of the peeling plate 7. The reflective film falls onto the substrate and adheres to the substrate as it moves. At the same time, the first electric push rod 13 pushes the second U-shaped plate 12 down so that the pressing roller 15 presses the reflective film onto the substrate to ensure that the reflective film is stably adhered to the substrate. After a portion of the reflective film is peeled off, the second electric push rod 18 pushes the cutting blade 14 down to cut the reflective film at the end of the tray 16, thus achieving the bonding of one reflective film to the substrate. When the next substrate moves below the tray 16, the bonding of the reflective film can continue.
