Among them, the feeding suction cup module 25 includes a feeding contour suction cup 251, a suction cup first connecting block 252 and a suction cup second connecting block 253. The suction cup first connecting block 252 is slidably connected to the feeding horizontal track 23, and the feeding horizontal cylinder 21 is connected to the suction cup first connecting block 252, which is used to drive the suction cup first connecting block 252 to slide along the feeding horizontal track 23. The feeding vertical track 24 is vertically arranged on the suction cup first connecting block 252, and one end of the suction cup second connecting block 253 is slidably connected to the vertical track, and the other end is connected to the feeding contour suction cup 251. The feeding vertical cylinder 22 is connected to the suction cup second connecting block 253, which is used to drive the suction cup second connecting block 253 to move up and down along the feeding vertical track 24. The loading carrier 26 is located at one end of the loading horizontal cylinder 21 and below the loading profile sucker 251. When the turntable platform 12 rotates to the working position, the feeding table 13 on the turntable platform 12 is parallel to the loading carrier 26 and is located at the other end of the loading horizontal track 23. The sucker adopts a vacuum sucker. This structure realizes the up-down and horizontal movement of the loading profile sucker 251, and can smoothly suck up the car sun visor in the loading carrier 26.

A positioning pin 273 is arranged on one side of the detection platform 271, and the positioning pin 273 is connected to a micro motor to realize the lateral adjustment of the automobile sun visor. The detection sensors 272 are arranged at the four corners of the detection platform 271 to detect whether the upper automobile sun visor is curled.

[0042] The feeding profiling suction cup 251 has two parallel suction cups. When the turntable platform 12 rotates to the working position, the distance between the feeding platform 13, the detection platform 271 and the feeding platform 13 is the same, and the distance is the same as the distance between the two suction cups.

The hot pressing cylinder 572 and the hot pressing block 573 with holes perform secondary hot stamping of the label on the automobile sun visor on the feeding table 13 to improve the hot stamping quality.

[0051] The working principle of this embodiment is:

[0052] The materials of the automobile sun visor are put into the loading carrier 26 in batches, and the loading profile sucker 251 sucks a piece of material and places it on the inspection table 271 for inspection. If the quality is qualified, the material will be subjected to the subsequent steps of hot stamping; if the quality is unqualified, the material will not be subjected to hot stamping. The loading profile sucker 251 continues to suck the material from the loading carrier 26, and at the same time sucks and moves the material on the inspection table 271 to the feeding table 13.

[0053] The turntable platform 12 rotates, so that the material tool on the feeding table 13 moves to the punching module 3, and the punching module 3 completes punching of the material tool.

[0054] The turntable platform 12 rotates, so that the material on the feeding table 13 moves to the thermal transfer module 4, and the thermal transfer module 4 completes the preliminary hot stamping of the material.

[0055] The turntable platform 12 rotates, so that the material on the feeding table 13 moves to the unloading module 5. The hot pressing unit 57 in the unloading module 5 first completes the secondary hot stamping of the material to improve the quality of hot stamping, and then sucks the material from the feeding table 13 through the unloading contour suction cup 551. At the same time, the two unloading carriers 563 on the unloading placement unit 56 move on the second horizontal track 562 of unloading, so that the material that passes the inspection of the detection table 271 and undergoes the hot stamping step falls into one of the unloading carriers 563, and the material that fails the inspection of the detection table 271 and does not undergo the hot stamping step falls into the other unloading carrier 563.

[0056] The device can realize loading, punching, thermal transfer, hot pressing and unloading, effectively improving the work efficiency. The device is controlled by a PLC controller as a whole, and its positioning and movement adopt existing control methods, so it will not be expanded in the embodiment.

[0057] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
