Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective film technology, and more specifically, to a multi-layer screen printing platform protective film structure. Background Technology
[0002] In the screen printing industry, screen printing platform protective film is a key component to ensure printing quality and platform protection. Traditional screen printing platform protective film designs generally adopt a disposable single-film mode, which means that after each printing task is completed, employees need to manually tear off the old protective film and replace it with a new one. Although this mode meets the basic protection needs to a certain extent, in actual operation, the frequent replacement of protective film undoubtedly increases the workload of employees and reduces work efficiency.
[0003] More specifically, the traditional method of using protective film requires employees to perform a series of precise and tedious actions each time it is replaced. This not only consumes valuable time but may also lead to untimely or inaccurate replacement due to human factors (such as improper operation or fatigue), thus affecting the subsequent printing quality. Therefore, we have made an improvement by proposing a multi-layer screen printing platform protective film structure. Utility Model Content
[0004] The technical problem to be solved by this utility model embodiment is that the use of disposable single-sheet protective film requires employees to manually tear off the old protective film and replace it with a new one after each printing task, which increases the workload of employees.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A multi-layer screen printing platform protective film structure includes: multiple protective film bodies, which are stacked together, and each of the multiple protective film bodies has a vacuum hole in its center. With this multi-layer protective film structure, employees only need to peel off the top layer of the protective film body after use to expose the next new layer, eliminating the need for frequent replacement of the entire protective film. This reduces operational actions and time. The multi-layer design also makes the replacement of the protective film bodies faster, allowing employees to quickly complete the replacement and improving production efficiency.
[0007] As an improvement of this utility model, the vacuum holes in the middle of the plurality of protective film bodies are interconnected.
[0008] As an improvement of this utility model, it also includes a protective component, which is disposed at the bottom of the lowest protective film body.
[0009] As an improvement of this utility model, the protective component is a release film layer, which is adhered to the bottom of the bottommost protective film body.
[0010] As an improvement of this utility model, a tear-off handle is fixedly connected to one side of each of the multiple protective film bodies, and the tear-off handle is used to tear off the protective film body.
[0011] As an improvement of this utility model, the ends of the multiple tear-off handles that are away from the protective film body are staggered.
[0012] As an improvement of this utility model, the external dimensions of the protective film body are the same as those of the screen printing platform.
[0013] As an improvement of this utility model, the protective film body is made of polyurethane material.
[0014] As an improvement of this utility model, the outer surface of the protective film body is provided with an antistatic coating; static electricity may attract dust and impurities, affecting the accuracy of screen printing, and may also damage electronic components and other workpieces. The antistatic coating can eliminate static electricity, avoid these problems, improve product quality, eliminate static electricity to avoid printing defects and workpiece damage, and improve product quality and corporate market reputation.
[0015] As an improvement of this utility model, the outer surface of the protective film body is provided with an anti-glare coating of nano-sized silica particles. The particle size of the silica particles is between 20-80 nanometers, and the coating thickness is controlled between 1-5 micrometers. The anti-glare coating changes the light path and reduces glare, allowing operators to see the screen printing process more clearly. At the same time, it reduces visual fatigue caused by strong light stimulation, improves work efficiency and quality, and reduces the defect rate and operational errors.
[0016] Compared with the prior art, the embodiments of this utility model have the following main advantages:
[0017] To address the problem of existing technologies using disposable single-sheet protective films, which require employees to manually peel off the old protective film and replace it with a new one after each printing task, increasing their workload, this application proposes a multi-layered protective film body. Employees only need to peel off the top layer of the protective film body after use to reveal the next new layer, eliminating the need for frequent replacement of the entire protective film. This reduces operational steps and time, and the multi-layered design allows for faster replacement of the protective film body, improving production efficiency. Attached Figure Description

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The reference herein to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0025] As described in the background section, traditional screen printing platform protective film designs generally adopt a single-use, single-film model. This means that after each printing task, employees need to manually peel off the old protective film and replace it with a new one. While this model meets basic protection needs to a certain extent, in actual operation, the frequent replacement of protective film undoubtedly increases the workload of employees and reduces work efficiency. More specifically, the traditional method of using protective film requires employees to perform a series of precise and tedious actions each time it is replaced. This not only consumes valuable time but may also lead to untimely or inaccurate replacement of the protective film due to human factors (such as improper operation or fatigue), thereby affecting the subsequent printing quality.
[0026] To solve this technical problem, this utility model provides a multi-layer screen printing platform protective film structure, which is used for the protection of screen printing platforms.
[0027] For details, please refer to Figures 1-4 The multi-layer screen printing platform protective film structure specifically includes:
[0028] Multiple protective film bodies 1 are stacked together, and each of the multiple protective film bodies 1 has a vacuum hole 101 in the middle.
[0029] The multi-layer screen printing platform protective film structure provided by this utility model allows employees to simply peel off the upper layer of the protective film body 1 after the protective film is used up, thus revealing the next new layer of the protective film body 1. This eliminates the need to frequently replace the entire protective film, thereby reducing operational actions and time. The multi-layer design also makes the replacement of the protective film body 1 faster, allowing employees to quickly complete the replacement of the protective film and improve production efficiency.
[0030] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0033] Example 1 of the multi-layer screen printing platform protective film structure of this utility model
[0034] Please refer to Figures 1-4 This utility model discloses a multi-layer protective film structure for a screen printing platform, comprising: multiple protective film bodies 1, which are stacked together, and each of the multiple protective film bodies 1 has a vacuum hole 101 in the middle. With this multi-layer protective film body structure, employees only need to peel off the upper protective film body 1 after use to expose the next new protective film body 1, eliminating the need for frequent replacement of the entire protective film, thus reducing operational actions and time. The multi-layer design allows for faster replacement of the protective film body 1, enabling employees to quickly complete the replacement and improving production efficiency. During the screen printing process, the vacuum hole 101 can be connected to the vacuum system of the screen printing platform, generating negative pressure to fix and protect the workpiece on the screen printing platform. This fixing method ensures that the workpiece will not shift during printing, thereby improving printing accuracy and stability.
[0035] Furthermore, the vacuum holes 101 in the middle of the multiple protective film bodies 1 are interconnected. The interconnected vacuum holes 101 can make the negative pressure evenly distributed on each layer of protective film bodies 1, ensuring that each layer of protective film bodies 1 can stably fix the workpiece, thereby improving the overall stability. The stable fixing effect reduces defects and rework caused by workpiece displacement and improves production continuity.
[0036] Example 2 of the multi-layer screen printing platform protective film structure of this utility model
[0037] Furthermore, the multi-layer screen printing platform protective film structure of this utility model also includes a protective component. The protective component is set at the bottom of the bottom layer of the protective film body 1, which reduces the possibility of dust and other impurities adhering to the adhesive surface of the bottom layer of the protective film body 1 before use. This allows the protective film body 1 to maintain good adhesion during pasting, avoids the impact of impurities on the pasting effect, and thus extends its service life. The tightly fitted protective film body 1 reduces the damage of foreign objects to the platform, and the stable working state improves the stability of the production process.
[0038] Furthermore, such as Figures 1-3 As shown, the protective component is a release film layer 2, which is attached to the bottom of the bottom protective film body 1. The release film is inexpensive and easy to purchase on the market. Its low cost, easy availability and convenient separation characteristics improve production efficiency and production continuity.
[0039] Furthermore, such as Figures 1-4 As shown, a tear-off handle 103 is fixedly connected to one side of each of the multiple protective film bodies 1. The tear-off handle 103 is used to tear off the protective film body 1, which greatly improves the convenience of operation for employees, significantly improves tear-off efficiency and reduces the risk of damage to the protective film body 1. The tear-off handle 103 provides a point of force when tearing, making the tearing action easier and smoother. The improved tear-off efficiency saves operation time and indirectly improves production efficiency.
[0040] Furthermore, such as Figure 1 and Figure 3 As shown, the ends of the multiple tear handles 103 furthest from the protective film body 1 are staggered, which facilitates hand operation of a single protective film body 1 during tearing, reduces accidental tearing and waste, and effectively reduces material loss. Because the staggered arrangement allows employees to clearly distinguish each tear handle 103 and accurately tear off the protective film body 1 that needs to be replaced, it reduces accidental tearing, thereby reducing material loss and saving costs.
[0041] Furthermore, the outer dimensions of the protective film body 1 are the same as those of the screen printing platform, which ensures that the protective film body 1 completely covers the screen printing platform, preventing ink and other substances from staining or scratching the platform, thus providing better protection, reducing damage to the screen printing platform, lowering equipment maintenance costs, and extending the platform's service life.
[0042] Furthermore, the protective film body 1 is made of polyurethane material, which has high wear resistance and a thickness range of 0.1-0.5 mm. The high wear resistance of polyurethane material makes the protective film body 1 more durable and can withstand multiple screen printing operations. The appropriate thickness not only provides protection but also avoids affecting the operator's observation of the screen printing process due to excessive thickness, ensuring operational visibility. The high wear resistance reduces the number of times the protective film needs to be replaced, thereby reducing costs and improving production quality.
[0043] Embodiment 3 of the multi-layer screen printing platform protective film structure of this utility model
[0044] Furthermore, the protective film structure of the multi-layer screen printing platform of this utility model is further provided with an anti-static coating on the outer surface of the protective film body 1. Static electricity may attract dust and impurities, affecting the screen printing accuracy, and may also damage electronic components and other workpieces. The anti-static coating can eliminate static electricity, avoid these problems, improve product quality, eliminate static electricity to avoid printing defects and workpiece damage, and improve product quality and corporate market reputation.
[0045] Antistatic coatings are generally composed of conductive materials, such as metal oxides (e.g., indium tin oxide, zinc oxide), conductive polymers (e.g., polyacetylene, polyaniline), and carbon nanomaterials (e.g., carbon nanotubes, graphene). When these materials are applied to the outer surface of the protective film body 1, they can quickly conduct static charge away when static electricity is generated, reducing the accumulation of static electricity on the surface of the protective film body 1, eliminating the adverse effects of static electricity on the screen printing process and the workpiece, thereby significantly improving product quality and enhancing the company's market reputation and product competitiveness.
[0046] Example 4 of the multi-layer screen printing platform protective film structure of this utility model
[0047] Furthermore, the protective film structure of the multilayer screen printing platform of this utility model is further provided with an anti-glare coating of nano-sized silica particles on the outer surface of the protective film body 1. The particle size of the silica particles is between 20-80 nanometers, and the coating thickness is controlled between 1-5 micrometers. By changing the refraction and scattering path of light in the above manner, glare is effectively reduced, and visibility in strong light environment is guaranteed.
[0048] The anti-glare coating alters the light path, reducing glare and allowing operators to see the screen printing process more clearly. It also reduces visual fatigue caused by strong light stimulation, improving work efficiency and quality. The clear field of vision and reduced visual fatigue improve work efficiency and quality, and reduce the defect rate and operational errors.
[0049] In use, peel off the release film layer 2 and stick the bottom protective film body 1 to the screen printing platform. The vacuum hole 101 corresponds to the vacuum system of the screen printing platform. The workpiece is placed on top of the top protective film body 1 and fixed by vacuum adsorption. During use, peel off the top protective film body 1 to expose the next new protective film body 1.
