Description

Technical Field

[0001] The invention relates to the technical field of hot stamping printing, and in particular to a hot stamping process plate alignment device and a plate alignment method. Background Art

[0002] The main material of hot stamping is electroplated aluminum, so hot stamping is also called electroplated aluminum hot stamping. Hot stamping uses the principle of heat transfer to transfer the aluminum layer in the electroplated aluminum to the surface of the substrate. The basic process is: when the electroplated aluminum is pressed by the hot stamping plate and the substrate, the heat of the electroplated aluminum melts the hot-melt silicone resin layer and adhesive on it. At this time, the viscosity of the melted silicone resin decreases, and the viscosity of the special heat-sensitive adhesive increases after being melted by heat, so that the aluminum layer is peeled off from the electroplated aluminum base film and transferred to the substrate at the same time. As the pressure is removed, the adhesive quickly cools and solidifies, and the aluminum layer is firmly attached to the substrate, completing a hot stamping process.

[0003] Before the hot stamping process is carried out, it is generally necessary to print the pattern of the substrate first to form a preliminary print, and then use the hot stamping process to attach the electroplated aluminum to the surface of the corresponding text or pattern of the preliminary print. When the existing hot stamping process requires alignment, generally according to the layout in the electronic file, a transparent plastic film (film) with a printed pattern is first made, and then the template is placed under the film, and the pattern on the template is aligned with the printed pattern on the film to complete the alignment.

[0004] However, the film needs to be processed separately, which requires that the film be processed first in the hot stamping process to achieve alignment, which not only increases the time of the hot stamping process, but also increases the hot stamping cost.

[0005] In addition, due to the influence of temperature, paper humidity, paper water absorption, ink and other conditions, there will be deviations between the positions of each pattern on the same preliminary print and the positions of the patterns in the electronic version. This will cause deviations between the printed pattern on the film and the pattern on the surface of the preliminary print, making it impossible to achieve the requirements of the hot stamping process for the plate.

[0006] In view of this, it is necessary to provide a new technical solution to solve the above problems. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0049] Example 1

[0050] like Figure 1 As shown, a hot stamping process alignment device includes: a working platform 10, an image acquisition device 30, a display device 40, an actuating mechanism 20 and a storage system.

[0051] The upper surface of the work platform 10 has a work surface for hot stamping process alignment. The storage system stores electronic documents containing printed patterns. The image acquisition device 30 is arranged above the work surface, and is used to perform real-time image acquisition of objects on the work surface. The image acquisition device 30 and the storage system are both communicatively connected to the display device 40, so that the display device 40 can simultaneously display the image acquired by the image acquisition device 30 and the printed pattern in the electronic document. The actuating mechanism 20 is fixedly connected to the work platform 10, and the actuating mechanism 20 is configured to drive the image acquisition device 30 to move above the work surface, so that the image acquisition device 30 can acquire images at various positions on the work surface.

[0052] As another embodiment of the present invention, the actuating mechanism 20 further includes a manipulator 50 for moving objects on the work surface. The manipulator 50 grabs the objects placed on the work surface by mechanical grabbing, adsorption, or pasting.

[0053] The work surface is provided with a registration area 12 and a template placement area 11. The registration area 12 is provided with a positioning mark 13. The positioning mark 13 is a positioning mark, which is used to position the heating plate or the preliminary printed product to be stamped in the registration area 12.

[0054] The actuating mechanism 20 is a three-axis motion control platform, which includes an X-axis actuating device, a Y-axis actuating device, and a Z-axis actuating device that can move independently. Among them, the X-axis actuating device and the Y-axis actuating device are used to drive the image acquisition device 30 to move above the worktable. The Z-axis actuating device is used to drive the image acquisition device 30 to move in the vertical direction. Since the three-axis motion control platform with the X-axis actuating device, the Y-axis actuating device, and the Z-axis actuating device belongs to the existing mature technology and can be directly purchased on the market, it will not be described here.

[0055] Example 2

[0056] Based on the same inventive concept, a hot stamping process alignment method is also provided, which uses the hot stamping process alignment device in Example 1 to align the plate, including the following steps:

[0057] S1. Placing a preliminary printed product to be hot stamped with one or more groups of patterns printed thereon at a preset position of a registration area on a workbench, and collecting and displaying images of the patterns on the preliminary printed product to be hot stamped.

[0058] S2, adjusting the position of the preliminary printed matter to be stamped, so that the pattern on the preliminary printed matter to be stamped completely overlaps with the pattern stored in the electronic document, and removing the preliminary printed matter to be stamped;

[0059] S3, placing the metal plate in a preset position of the registration area on the workbench, placing the hot stamping template on the surface of the metal plate, and collecting and displaying an image of the pattern on the hot stamping template;

[0060] S4. Adjust the position of the hot stamping template so that the pattern on the hot stamping template completely overlaps with the pattern stored in the electronic document, and fix the hot stamping template to the metal plate to complete the registration.

[0061] In this embodiment, a hot stamping process alignment method specifically includes:

[0062] Place the preliminary printed product to be hot stamped with one or more groups of patterns on a preset position in the registration area of ​​the workbench so that the positioning mark of the preliminary printed product to be hot stamped coincides with the positioning mark line on the workbench.

[0063] It should be noted that when the preliminary printed product to be hot stamped is placed at a preset position in the registration area on the workbench, the positioning mark on the surface of the workbench can be combined with the positioning mark of the preliminary printed product to be hot stamped to determine the accuracy of the hot stamping template position.

[0064] The image acquisition device is used to acquire the image of the surface of the preliminary printed matter to be hot stamped in real time, and the acquired image of the pattern on the preliminary printed matter to be hot stamped is displayed on the display device.

[0065] The image of the pattern on the product to be hot stamped is compared with the pattern stored in the electronic document on the display device.

[0066] The position of the preliminary printed product to be hot-stamped is adjusted so that the image of the pattern on the product to be hot-stamped and the pattern stored in the electronic document completely overlap on the display device.

[0067] Remove the preliminary printed product to be hot stamped from the workbench.

[0068] Place the metal plate into the preset position of the alignment area on the workbench so that the positioning mark of the metal plate coincides with the positioning mark on the workbench.

[0069] The hot stamping template is placed on the surface of the metal plate, and an image acquisition device is used to obtain an image of the hot stamping template surface in real time, and the obtained image of the hot stamping template surface is displayed on a display device.

[0070] It should be noted that, in this process, the number of hot stamping templates corresponds to the number of patterns on the preliminary printed product to be hot stamped, so that each group of patterns on the preliminary printed product to be hot stamped has a corresponding hot stamping template.

[0071] The image of the surface pattern of the hot stamping template is compared with the pattern stored in the electronic document on the display device.

[0072] The position of the hot stamping template is adjusted so that the image of the pattern on the hot stamping template and the pattern stored in the electronic document completely overlap on the display device.

[0073] Use adhesive to fix the hot stamping template on the metal plate to complete the hot stamping process.

[0074] In addition, in the process of adjusting the position of the preliminary printed product to be hot stamped so that the image of the pattern on the product to be hot stamped and the pattern stored in the electronic document completely overlap on the display device, if there is a printing problem so that the image of the pattern on the product to be hot stamped and the pattern stored in the electronic document cannot completely overlap on the display device, it also includes:

[0075] The patterns stored in the electronic document are broken up, and the positions of the patterns that are not completely aligned are adjusted so that they completely overlap with the patterns on the product to be hot stamped on the display device.

[0076] Lock the scattered patterns in the electronic document.

[0077] After the registration is completed, the metal plate with the hot stamping template can be placed in the corresponding hot stamping equipment for hot stamping on the surface of the printed matter.

[0078] It should be noted that the above steps can also be applied to the embossing process of printed materials. It is only necessary to replace the metal plate in the above process with the corresponding knife plate. After the plate is aligned, it is placed on the corresponding equipment for embossing, so that the corresponding pattern protrudes from the surface of the printed material to increase the three-dimensional effect.

[0082] S31, placing the metal plate in a preset position of the alignment area on the workbench, so that the positioning mark of the metal plate coincides with the positioning mark line on the workbench.

[0083] S32, placing the hot stamping template at a preset position on the upper surface of the workbench, using an image acquisition device to acquire an image of the hot stamping template surface in real time, and displaying the acquired image of the hot stamping template surface on a display device.

[0084] It should be noted that when the hot stamping template is placed at a preset position on the upper surface of the workbench, the positioning mark on the upper surface of the workbench can be combined with the positioning mark of the hot stamping template to determine the accuracy of the position of the hot stamping template.
