Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting film bonding technology, specifically a high-precision positioning and bonding mechanism for holographic anti-counterfeiting film. Background Technology

[0002] Anti-counterfeiting label lamination is a common technical method aimed at improving the durability and security of anti-counterfeiting labels, thereby ensuring product safety. Lamination technology forms a protective layer by covering the label surface with a thin film, making the label more wear-resistant, waterproof, and oil-proof, thus extending the label's lifespan. At the same time, lamination can prevent the label from being peeled off or tampered with, improving label security. In the field of anti-counterfeiting packaging, the application of holographic anti-counterfeiting film is becoming increasingly widespread. However, existing holographic anti-counterfeiting film lamination mechanisms have many problems in terms of positioning accuracy and lamination quality.

[0003] For example, a production device for anti-counterfeiting protective films for electronic screens, as described in application number CN202222848933.9, includes a protective film production mechanism, a first pressing roller group and a second pressing roller group sequentially arranged at the output end of the protective film production mechanism, as well as a first feeding roller, a first receiving roller, and a second receiving roller. The first feeding roller feeds a base film with a label paper printed on it to the first pressing roller group. The label paper is printed with an anti-counterfeiting code. The first pressing roller group adheres the label paper on the base film to the protective film output from the protective film production mechanism. The first receiving roller winds up the base film after it is separated from the label paper. The second receiving roller winds up the protective film with the label paper adhered, and the traction speed of the second receiving roller is not equal to the traction speed of the first receiving roller. This utility model sets up a first and a second pressing roller group at the output end of the protective film production mechanism to adhere the base film with the label paper to the protective film, so that the protective film is attached with a label paper with an anti-counterfeiting code, realizing the anti-counterfeiting function, and the QR code has higher quality and clearer clarity. However, this positioning and bonding mechanism is difficult to adapt to the bonding needs of products of different sizes and shapes, and is prone to defects such as misalignment, bubbles, and wrinkles. In addition, it lacks effective assistance and optimization functions for the bonding process, resulting in low production efficiency and difficulty in meeting the needs of large-scale industrial production.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a high-precision positioning and bonding mechanism for holographic anti-counterfeiting film. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision positioning and bonding mechanism for holographic anti-counterfeiting film to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision positioning and bonding mechanism for holographic anti-counterfeiting film, comprising a base platform and a temperature compensation bonding mechanism. The temperature compensation bonding mechanism is fixedly connected to the top of the base platform, and the temperature compensation bonding mechanism includes a fixing frame fixedly connected to the top position of the base platform. A guide roller is provided on one side of the fixing frame, and multiple sets of heating wires are fixedly connected inside the guide roller. A heat-conducting medium is provided on the outer surface of the guide roller.

[0007] Preferably, a support frame is fixedly connected to the top of the base platform, and a tension adjustment mechanism is provided on one side of the support frame. The tension adjustment mechanism includes an unwinding shaft located on one side of the support frame, and a damper is provided on the outer surface of the unwinding shaft. A spring is fixedly connected to one end of the damper.

[0008] Preferably, one end of the unwinding shaft is equipped with a motor, and the inner surface of the base platform has multiple sets of vacuum adsorption holes.

[0009] Preferably, a vacuum pump is provided at the bottom of the vacuum adsorption hole, and a slide rail is provided on the inner surface of the base platform.

[0010] Preferably, the slide rail has an internal sliding connection with a fixed plate, and the inner surface of the fixed plate is threaded with a double-segment threaded rod.

[0011] Preferably, a clamping block is fixedly connected to the top of the double-segment threaded rod, and a rubber layer is fixedly connected to one side of the clamping block.

[0012] Preferably, a cutting device is fixedly connected to the top of the base platform, and a collection trough is slidably connected to the base platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a temperature-compensated bonding mechanism, when the ambient temperature is low or the film material or product material is sensitive to temperature, raises the surface temperature of the bonding roller by energizing the heating wire. The heat generated by the heating wire is evenly transferred to the roller surface through the heat-conducting medium. The warm roller surface can reduce the hardness of the film material, improve its flexibility and bonding performance, and avoid film wrinkles or poor bonding due to low temperature. The heating temperature can be manually adjusted according to actual production needs, and the appropriate bonding pressure can be adjusted under different temperature conditions to ensure the bonding effect.

[0015] 2. By setting up a tension adjustment mechanism, when the unwinding speed of the film material fluctuates and causes tension changes, the spring is compressed or stretched to change the wrap angle and tension of the film material, while the damper effectively suppresses excessive oscillation of the unwinding shaft and avoids large fluctuations in tension.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a high-precision positioning and bonding mechanism for holographic anti-counterfeiting film includes a base platform 1 and a temperature-compensated bonding mechanism 2. The temperature-compensated bonding mechanism 2 is fixedly connected to the top of the base platform 1. The temperature-compensated bonding mechanism 2 includes a fixed frame 201 fixedly connected to the top of the base platform 1. A guide roller 202 is provided on one side of the fixed frame 201, and multiple sets of heating wires 203 are fixedly connected inside the guide roller 202. A heat-conducting medium 204 is provided on the outer surface of the guide roller 202. The base platform 1 is made of high-strength aluminum alloy with a finely machined surface and high flatness. The base platform 1 is used to support the product to be bonded and to install other functional components, providing a stable foundation for the entire bonding process. The guide roller 202 guides the direction of the film material, ensuring it accurately enters the bonding area. Multiple sets of heating wires 203 are evenly distributed on the inner wall of the guide roller 202. When in an unsuitable temperature environment, the heat generated by the heating wires 203 is transferred to the roller surface through the heat-conducting medium 204, ensuring the bonding effect of the film material.

[0023] like Figure 4As shown, a support frame 3 is fixedly connected to the top of the base platform 1, and a tension adjustment mechanism 4 is provided on one side of the support frame 3. The tension adjustment mechanism 4 includes an unwinding shaft 401 located on one side of the support frame 3, and a damper 402 is provided on the outer surface of the unwinding shaft 401. A spring 403 is fixedly connected to one end of the damper 402. The unwinding shaft 401 is used to install the holographic anti-counterfeiting film roll. The dampers 402 and springs 403 at both ends of the unwinding shaft 401 adjust the unwinding tension of the film material to ensure that the film material is released smoothly and at a uniform speed.

[0024] Furthermore, a motor 5 is provided at one end of the unwinding shaft 401, and multiple sets of vacuum adsorption holes 6 are opened on the inner surface of the base platform 1. A vacuum pump 7 is provided at the bottom of the vacuum adsorption holes 6, and a slide rail 8 is opened on the inner surface of the base platform 1. The motor 5 drives the unwinding shaft 401 to wind up. The vacuum adsorption holes 6 are connected to the vacuum pump 7 through pipes. Before bonding, the vacuum pump 7 is started, and the product is firmly adsorbed onto the base platform 1 through the vacuum adsorption holes 6 to prevent the product from moving due to force during the bonding process. At the same time, vacuum adsorption can effectively remove the air between the film material and the product surface and reduce the generation of air bubbles.

[0025] Furthermore, the slide rail 8 has an internal sliding connection with a fixed plate 9, and the inner surface of the fixed plate 9 is threaded with a double-segment threaded rod 10. The top of the double-segment threaded rod 10 is fixedly connected with a clamping block 11, and one side of the clamping block 11 is fixedly connected with a rubber layer. The rotation of the double-segment threaded rod 10 drives two sets of symmetrical clamping blocks 11 to clamp and fix different products, preventing the products from shifting during the bonding process.

[0026] Furthermore, a cutting device 12 is fixedly connected to the top of the base platform 1, and a collection tank 13 is slidably connected to the base platform 1. The operator cuts the membrane material using the cutting device 12. The excess material generated during cutting falls into the collection tank 13 under gravity. The collection tank 13 is then removed for cleaning to keep the work area clean, reduce the interference of excess material on subsequent production, and improve production efficiency.

[0027] Working Principle: When using this high-precision positioning and bonding mechanism for holographic anti-counterfeiting film, first, the base platform 1 is horizontally installed at the work site to ensure its stability. Then, the temperature compensation bonding mechanism 2, tension adjustment mechanism 4, and vacuum pump 7 are fixedly installed and adjusted. The product to be bonded is placed on the base platform 1. The product is fixed by rotating the double-segment threaded rod 10 inside the slide rail 8 and driving the clamping block 11. The vacuum pump 7 is started to perform vacuum adsorption through the vacuum adsorption hole 6. The holographic anti-counterfeiting film is installed and rolled onto the unwinding shaft 401. The motor 5 is started, and the film material passes through the damper 402, spring 403, and guide roller 202 on one side of the fixing frame 201 into the bonding area. Then, according to the characteristics of the product and the film material, the temperature of the heating wire 203 inside the temperature compensation bonding mechanism 2 is adjusted. The heat transfer medium 204 brings the appropriate temperature to the film material. Finally, the operator controls the cutting device 12 to cut the excess film material, and the collection tank 13 collects the excess material. This is the working principle of the high-precision positioning and bonding mechanism for holographic anti-counterfeiting film.
