DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the masking device 100 in one embodiment of the utility model includes a frame 10, an ink transfer assembly and a die-cutting assembly. The frame 10 is equipped with a feed shaft 11, a separation roller 12 and an attachment roller 17, wherein the feed shaft 11 is used to roll up the tape to be masked and punched, and the tape is separated into a release film and an adhesive film at the separation roller 12, and the release film and the adhesive film continue to be transported backward along two paths, wherein the release film is transported to the rear end along path A, and the adhesive film is transported backward along path B. The ink transfer assembly is located on path B and is arranged between the separation roller 12 and the die-cutting assembly, and is used to apply ink on the surface of the adhesive film. After the ink is applied, the adhesive film is reattached to the surface of the release film at the attachment roller 17, and then transferred to the die-cutting assembly for punching according to product requirements and ink shape.

[0024] In the actual production process, some products require a non-continuous ink layer to be formed on the tape, and in order to facilitate subsequent use, the ink area needs to be punched. Therefore, the utility model integrates an ink transfer component and a die-cutting component on the frame 10. After the masking is completed, the tape can be punched immediately according to customer needs and the shape of the ink area, avoiding operations such as winding, re-unrolling and punching, reducing the operating steps and improving production efficiency.

[0025] like Figure 1As shown, the die-cutting assembly includes a roller cutter 51, a roller cutter bottom roller 52 and a roller cutter pressure rod 53. The roller cutter 51 and the roller cutter bottom roller 52 are arranged opposite to each other, and the masked tape passes between the two. The roller cutter pressure rod 53 connects and drives the roller cutter bottom roller 52 to approach the roller cutter 51 to press the tape onto the roller cutter 51 to complete the punching, and drives the roller cutter bottom roller 52 away from the roller cutter 51 after the punching is completed, thereby keeping the tape away from the roller cutter to prevent excessive punching.

[0026] The die-cutting assembly also includes a base 54, which is detachably mounted on the frame 10 and is used to provide an installation position for the roller cutter 51, the roller cutter bottom roller 52 and the roller cutter pressure rod 53. When the finished product does not need to be punched, the die-cutting assembly can be stopped, or the base 54 can be directly removed from the frame 10.

[0027] It is easy to imagine that different customers have different requirements for punching shapes, so it is often necessary to replace the roller cutter 51 with different cutting edges during production. Therefore, in one embodiment, the roller cutter 51 is detachably fixed to the base 54, and can be quickly switched when the punching shape is changed when needed, with high flexibility.

[0028] Preferably, the die-cutting assembly further includes a first sensor 55 for sensing the ink area on the tape and notifying the system to control the roller cutter 51 to perform die cutting. Figure 2 As shown in the figure, the black first area 201 on the tape 200 (only part of the area is shown) is the ink coating area, the rectangular area 202 surrounding the ink coating area is the punching area, and the black part in the lower right corner is the identification point 203. During the production process, the ink transfer component applies ink to the first area 201 and the identification point 203 of the film, and the die-cutting component controls the roller knife 51 to punch the tape only after the first sensor 55 detects the ink at the identification point 203, so as to improve the accuracy of punching and improve the yield rate.

[0029] Furthermore, the die-cutting component is also provided with a second sensor 56, which is arranged at the rear end of the roller cutter 51, and is used to detect the shape of the rectangular area 202 after the punching is completed, and the position of the first area 201 in the rectangular area 202. The back-end system determines whether it meets the product requirements (such as the presence of a position deviation of the first area 201 in the rectangular area 202), and then reduces the defective rate by adjusting the roller cutter 51 cutting time, speed and other parameters.

[0030] After the masking device 100 in this embodiment is equipped with the first sensor 55 and the second sensor 56, it can cooperate with the equipment system to accurately locate the product position, so that the punching size is more accurate. Before the improvement, the flat knife punching was used, and the punching output was 700 PCS / H, and after the improvement, it was 1800 PCS / H, which increased the production capacity by 257%. And by changing the speed of the roller knife 51 and adjusting the punching position, it can be ensured that the size of each product meets the customer's needs. The defective rate before the improvement was 4%, and the defective rate after the improvement was 1%.

[0031] like Figure 1 As shown, the ink transfer assembly includes an ink cartridge 41, an ink transfer bottom roller 42 and a plurality of ink transfer rollers 43, wherein the ink cartridge 41 is used to contain ink, the adhesive film passes through the ink transfer bottom roller 42 during transmission, the plurality of ink transfer rollers 43 are sequentially arranged between the ink cartridge 41 and the ink transfer bottom roller 42, and are only used to transfer ink to each other, and finally the ink transfer roller 43 away from the ink cartridge 41 applies the ink to the surface of the adhesive film.

[0032] Since different customers have different requirements for ink layer shapes, the roller cutter 51 with different shapes needs to be frequently replaced in actual use. Therefore, in one embodiment, at least the ink transfer roller 43 for performing the final ink coating operation (i.e., close to the ink transfer bottom roller 42) is detachably mounted on the frame 10.

[0033] Preferably, the ink transfer assembly also includes a scraper 44, which is arranged on one side of one of the ink transfer rollers 43, and is used to adjust the thickness of the ink on the ink transfer roller 43 to avoid the ink being coated on the film being too thick, resulting in the ink spreading out after being re-attached to the release film, resulting in a large difference between the shape and the target shape, or the ink layer being too thick to affect subsequent use.

[0034] Furthermore, the ink transfer assembly also includes a light irradiator 45, which is arranged at the rear end of the ink transfer bottom roller 43 and is used to irradiate the adhesive film to quickly solidify the surface ink.

[0035] Preferably, the frame 10 is also provided with a deviation corrector 15, which is arranged between the ink transfer assembly and the discharge shaft 11, and is used to correct the transmission posture of the tape to be masked, so that the material feeding is more accurate and ensures that the tape to be masked is transmitted to the rear along the same position.

[0036] like Figure 1 As shown, the frame 10 is also provided with a plurality of auxiliary rollers 16, which can be arranged at various positions on the frame 10 and between different components, and are used to adjust the direction of the tape to facilitate the respective operation processes of different components.

[0037] Preferably, a first material receiving shaft 13 is provided on the frame 10 for receiving the punched tape, and a second material receiving shaft 14 is provided on the frame 10 for receiving the punched waste for easy recycling.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
