Description

Technical Field

[0001] The invention relates to the field of cold-ironing and laminating equipment, and in particular to a cold-ironing and laminating device utilizing a baffle for positioning and alignment. Background Art

[0002] Cold stamping is a printing technology that uses a relatively low temperature to laminate an anodized aluminum film onto a substrate by pressing. During the cold stamping process, in order to improve the aesthetics of the anodized aluminum part laminated onto the substrate, a corresponding pattern is set on the anodized aluminum film. During the cold stamping, the pattern on the anodized aluminum film needs to be accurately aligned with the pattern on the substrate so that the pattern on the anodized aluminum film can be accurately transferred and laminated onto the corresponding pattern on the substrate. The commonly used method is to set a color mark at the edge blank of the anodized aluminum film and the substrate and combine it with a photoelectric sensor for position detection, and to achieve positioning and alignment of the anodized aluminum film and the pattern on the substrate by positioning the position of the color mark. This method is mainly used for positioning and aligning paper substrates. When the substrate is a metal sheet, it is difficult to accurately print the color mark on the metal sheet. At the same time, the metal sheet's own reflection characteristics of light can easily affect the detection of the color mark, resulting in a decrease in the accuracy of positioning and alignment, affecting the lamination accuracy. Summary of the invention

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cold stamping composite device that uses a baffle for positioning and alignment, comprising a substrate conveying device, a transfer film unwinding guide device and a pressing composite device, the substrate conveying device is provided with a baffle positioning mechanism, the baffle positioning mechanism is located in the upward direction of the pressing composite device, the baffle positioning mechanism includes a flipping drive mechanism and a forward positioning baffle, the flipping drive mechanism is arranged below the substrate conveying device and is connected to the forward positioning baffle drive; the transfer film unwinding guide device is provided with a transfer film positioning detection device, and a positioning mark is provided on the corresponding transfer film, and the transfer film positioning detection device is used to detect and position the positioning mark on the transfer film.

[0005] Specifically, there are two groups of baffle positioning mechanisms, both of which are arranged in the upward direction of the pressing composite device, and the distance between the two groups of baffle positioning mechanisms is at least one length of the substrate.

[0006] Specifically, the baffle positioning mechanism also includes a side positioning mechanism, and the side positioning mechanism includes a fixed side baffle and a movable side baffle, and the movable side baffle is driven and connected by a linear drive mechanism.

[0007] Specifically, the linear drive mechanism is drivingly connected to the movable side baffle through an elastic component.

[0008] Specifically, a pressure sensor is arranged between the elastic component and the movable side baffle.

[0009] The beneficial effect of the present invention is that: by adopting a baffle positioning mechanism, the metal sheet substrate is positioned from the forward direction and the side direction of the substrate, and the transfer film is positioned in cooperation with the photoelectric sensor of the transfer film, thereby achieving accurate alignment between the substrate and the transfer film and improving the accuracy of cold stamping and lamination. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Attached Figure 1 It is a side structural view of the cold foil laminating device when the forward positioning baffle blocks the substrate in the embodiment; Attached Figure 2 It is a side structural view of the cold foil laminating device when the forward positioning baffle releases the substrate in the embodiment; Attached Figure 3 It is a top view of the structure of the cold-ironing compound device in the embodiment. DETAILED DESCRIPTION

[0011] Example 1, reference Figure 1-3 A cold stamping composite device using a baffle for positioning and alignment comprises a substrate conveying device 1, a transfer film unwinding guide device 2 and a pressing composite device 3, wherein the substrate conveying device 1 is provided with a baffle positioning mechanism 4, the baffle positioning mechanism 4 is located in the upward direction of the pressing composite device 3, the baffle positioning mechanism 4 comprises a flipping driving mechanism 41 and a forward positioning baffle 42, the flipping driving mechanism 41 is arranged below the substrate conveying device 1 and is drivingly connected to the forward positioning baffle 42; the transfer film unwinding guide device 2 is provided with a transfer film positioning detection device 5, and a positioning mark is provided on the corresponding transfer film, and the transfer film positioning detection device 5 is used to detect and position the positioning mark on the transfer film.

[0012] In this embodiment, the baffle positioning mechanism 4 is used to position the substrate made of metal or other hard materials, and the transfer film positioning detection device 5 is used to position the transfer film. The combination of the two can accurately position and align the substrate and the transfer film before they enter the pressing and compounding device 3, so that the pattern on the transfer film can be aligned with the pattern on the substrate. Specifically, the baffle positioning mechanism 4 drives the forward positioning baffle 42 to rotate through the flip driving mechanism 41, blocking the substrate for limited positioning or releasing the substrate so that it can be transported forward to be compounded with the transfer film at the pressing and compounding device 3; the transfer film positioning detection device 5 can use a photoelectric sensor and cooperate with the positioning mark set on the transfer film to detect and position the transfer film.

[0013] In a further embodiment, there are two groups of baffle positioning mechanisms 4, both of which are arranged in the upward direction of the pressing composite device 3, and the distance between the two groups of baffle positioning mechanisms 4 is at least the length of a substrate. By setting up two groups of baffle positioning mechanisms 4, the distance between the front and rear substrates can be controlled. Since the pattern transferred from the transfer film to the substrate is repeated continuously, and the distance between the two identical patterns is fixed, in order to facilitate the control of the transmission speed of the transfer film and the substrate without frequently adjusting the transmission speed of the two, the distance between the front and rear substrates also needs to be a fixed value. By setting up two groups of front and rear baffle positioning mechanisms 4, the distance between the front and rear substrates can be fixed, thereby facilitating the transmission control of the transfer film and the substrate and improving the accuracy of the alignment of the two.

[0014] In a further embodiment, the baffle positioning mechanism 4 further includes a side positioning mechanism 6, the side positioning mechanism 6 includes a fixed side baffle 61 and a movable side baffle 62, and the movable side baffle 62 is driven and connected by a linear drive mechanism 63. The linear drive mechanism 63 is driven and connected to the movable side baffle 62 through an elastic component 64. A pressure sensor 65 is provided between the elastic component 64 and the movable side baffle 62. The side positioning mechanism 6 can limit the position of the substrate on the side to prevent the substrate from shifting in the lateral direction. Specifically, the fixed side baffle of the side positioning mechanism 6 is used to resist the substrate, and the movable side baffle 62 is used to push the substrate toward the fixed side baffle 61 so that it is against the fixed side baffle 61, thereby realizing the limited positioning of the substrate in the lateral direction. In order to avoid damage to the substrate, the linear drive mechanism 63 that drives the movable side baffle 62 drives and connects the movable side baffle 62 through an elastic component 64, wherein the elastic component 64 can be a component with an elastic buffering effect such as a spring component, and a pressure sensor 65 can be set between the elastic component 64 and the movable side baffle 62 to detect the pressure applied by the movable side baffle 62 on the substrate, thereby preventing the movable side baffle 62 from applying excessive pressure on the substrate and causing damage to the substrate.

[0015] Of course, the above are only preferred embodiments of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
