[0027] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0028] like Figure 1-Figure 3The device for staggered hot stamping of automobile exteriors shown in the figure comprises a machine base 1, which serves as the foundation of the entire device and is fixed on the ground to provide stable support for other components. A die table 2, a contoured membrane 3, a scraper mechanism 4, a heated hot stamping jig 5, a transverse hot stamping servo mechanism 6, a longitudinal hot stamping servo mechanism 7 and a lifting and pressing mechanism 8 are arranged in sequence above the machine base 1. Among them, the die table 2 is the basic workbench in the hot stamping process, on which the automobile exterior trim to be hot stamped can be placed. The contoured membrane 3 has a shape that matches the automobile exterior trim to be hot stamped. The function of the contoured membrane 3 is to provide a supporting surface that matches the shape of the automobile exterior trim, so that the hot stamping film can fit tightly on the exterior trim to achieve a precise hot stamping effect. The main function of the scraper mechanism 4 is to remove excess hot stamping film and residues to ensure that the hot stamping surface is clean and smooth. The existence of the heated hot stamping jig 5 can provide a stable and uniform heat source to ensure that the hot stamping material reaches the required temperature. The transverse hot stamping servo mechanism 6 is responsible for controlling the movement of the hot stamping film in the transverse direction. The mechanism drives the hot stamping film to accurately position and move in the transverse direction through a servo motor and a transmission device to achieve a transverse hot stamping effect. The longitudinal hot stamping servo mechanism 7, which is used in conjunction with the transverse hot stamping servo mechanism 6, is responsible for controlling the movement of the hot stamping film in the longitudinal direction. The transverse hot stamping servo mechanism 6 and the longitudinal hot stamping servo mechanism 7 work together to enable the hot stamping film to move on the mold table according to a preset trajectory and speed to achieve staggered hot stamping. The main function of the lifting and pressing mechanism 8 is to achieve a tight pressing of the hot stamping film and the automobile exterior parts.

[0029] The lifting and pressing mechanism 8 includes a pressing plate 8-1 and a pressing bracket 8-2.

A hot stamping film unwinding shaft 6-2 is installed at one end of the frame 6-1 for placing the film roll to be hot stamped. A servo motor 2 6-3 is provided on the frame 6-1 at the same end as the hot stamping film unwinding shaft 6-2. The servo motor 2 6-3 drives the hot stamping film unwinding shaft 6-2 to unwind through a synchronous belt and a pulley 6-4. A hot stamping film rewinding shaft 6-5 is installed at the other end of the frame 6-1 along the hot stamping film transmission path. A servo motor 3 6-6 is provided on the frame 6-1 at the same end as the hot stamping film rewinding shaft 6-5.

[0039] The specific operation method of the utility model is as follows:

[0040] During operation, the operator places the automobile exterior products to be hot stamped on the contoured tire mold 3, presses the start button, and the transverse hot stamping servo mechanism 6 automatically rolls out the hot stamping film according to the set length. The lifting and pressing mechanism 7 descends and presses to perform the hot stamping action. The hot stamped products are taken out manually, and the automobile exterior products are re-placed. The start button is pressed. At this time, the longitudinal hot stamping servo mechanism 7 moves longitudinally in the set direction, thereby driving the transverse hot stamping servo mechanism 6 to move longitudinally with the longitudinal hot stamping servo mechanism 7. At the same time, the transverse hot stamping servo mechanism 6 rolls out or reels in accordance with the set length, thereby realizing the arbitrary change of the position of the hot stamping film. The lifting and pressing mechanism 8 descends and presses to perform the hot stamping action, and the hot stamped products are taken out manually. In this way, the equipment completes a hot stamping cycle, that is, the longitudinal and transverse hot stamping are performed multiple times until the hot stamping film can no longer be hot stamped within the cycle, and the transverse hot stamping servo mechanism 6 will re-roll the hot stamping film according to the set length to enter the next cycle.
