Abstract
Description
Technical Field
[0001] This utility model relates to the field of polycarbonate processing, and more specifically, to a support device for coating optical thin films on polycarbonate surfaces. Background Technology
[0002] Polycarbonate, as a high-performance thermoplastic engineering plastic, has been widely used in the optical field due to its high transparency, good mechanical properties and thermal stability. However, PC material itself has the disadvantages of low hardness and poor wear resistance, which limits its application in some scenarios with high surface performance requirements. In order to improve the surface hardness and wear resistance of PC material, an optical film is usually coated on its surface. During the coating process, a stable and reliable support device is needed to ensure that the position of the polycarbonate sheet is fixed in order to achieve a uniform and high-quality coating effect.
[0003] A search revealed that Chinese Patent Publication No. CN111468368B discloses "A surface coating system for optical thin films, comprising a base box and a vertical box fixedly installed on the top of the base box, characterized in that: a switching coating mechanism is provided inside the vertical box, and an electromagnetic three-way valve is fixedly installed inside the vertical box and on one side of the switching coating mechanism via a connecting plate; thin film guiding mechanisms are fixedly connected to both sides of the front of the vertical box via connecting plates. This invention relates to the field of optical thin film processing technology. This surface coating system for optical thin films can achieve double-sided switching coating by using a dual-roller switching coating mechanism. The switching operation is simple, and there is no need to reinstall the thin film rollers for secondary coating, which greatly saves a lot of working time for production personnel and significantly improves the efficiency of thin film coating. At the same time, the switching coating mechanism has a simple structure and is easy to implement, which greatly reduces the cost of thin film coating and eliminates the need for real-time monitoring by production personnel." However, it still has the following drawbacks:
[0004] (1) In actual use, the device cannot adjust the support roller. The position and height of the support roller are fixed. When processing optical films of different thicknesses and materials, the support height of the support roller cannot be adjusted according to the characteristics of the film. If it is too tight, it will cause the film to stretch and deform. If it is too loose, the film will wrinkle and shift during the coating process, affecting the uniformity of the coating layer and limiting its applicability.
[0005] (2) In actual use, the device cannot finely adjust the fixed positioning setting of the film size. The existing fixed positioning structure is difficult to adjust accurately according to the optical film. During coating, the film is prone to displacement due to inaccurate positioning, resulting in waste of coating or incomplete coating, which affects product quality and increases the product defect rate. To this end, a polycarbonate surface optical film coating support device is proposed. Utility Model Content
[0006] The purpose of this invention is to address the problems existing in current devices that, in practical use, cannot adjust the support rollers or adjust the support height of the support rollers according to the characteristics of the film, thus affecting the uniformity of the coating layer and limiting the scope of application. Furthermore, the current devices cannot precisely adjust the fixed positioning settings for the film size, which easily leads to deviation during coating and increases the product defect rate. This invention provides a polycarbonate surface optical film coating support device to solve the problems mentioned in the background art.
[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0008] The present invention is as follows: a support device for coating optical thin films on a polycarbonate surface, comprising a housing, a support component for supporting the optical thin film fixedly installed on the top of the housing, and an adjustment component for adjusting the positioning of the optical thin film provided on the housing;
[0009] The support assembly includes several support columns fixedly installed at the bottom of the outer shell, a feeding trough opened at the top of the outer shell, a support plate fixedly installed at the top of the outer shell, two first motors fixedly installed inside the support plate, rollers fixedly installed at the output ends of the first motors, a lifting plate fixedly installed on one side of the support plate, a rotating disk fixedly installed on one side of the lifting plate, two extrusion rollers rotatably installed on one side of the rotating disk, a rack fixedly installed on one side of the lifting plate, two fixing plates fixedly installed on one side of the support plate, a protective shell fixedly installed on one side of the fixing plates, a second motor fixedly installed on one side of the protective shell, a rotating column fixedly installed at the output end of the second motor, and gears fixedly installed around the circumference of the rotating column, the gears meshing with the rack.
[0010] As a preferred technical solution of this utility model, the adjustment assembly includes a limiting plate fixedly installed on one side of the roller, an adjustment block fixedly installed on the limiting plate and one side of the roller, an adjustment rod slidably installed between the two adjustment blocks, an adjustment plate inserted into the top of the adjustment rod, rubber pads fixedly installed on both sides of the adjustment plate, a plurality of adjustment grooves opened on one side of the adjustment plate, and a positioning screw threaded on one side of the adjustment groove.
[0011] As a preferred technical solution of this utility model, a storage rack is fixedly installed on one side of the outer shell, a plurality of sliding rods are fixedly installed on one side of the storage rack, and a storage box is fixedly installed on the top of two of the sliding rods.
[0012] As a preferred technical solution of this utility model, a fixing rod is fixedly installed on the top of the outer shell, a sunshade is fixedly installed on the top of the fixing rod, and a plurality of drainage grooves are provided on the top of the sunshade.
[0013] As a preferred technical solution of this utility model, a waste trough is provided on one side of the outer shell, and a waste box is fixedly installed on the top of the waste trough.
[0014] As a preferred technical solution of this utility model, a placement rack is fixedly installed on one side of the outer shell, and several partition plates are fixedly installed on the top of the placement rack.
[0015] As a preferred technical solution of this utility model, an anti-slip pad is fixedly installed at the bottom of the support column, and an anti-slip pattern is fixedly installed at the bottom of the anti-slip pad. The anti-slip pattern is made of rubber.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. With its designed support components, the support column at the bottom of the casing provides a stable foundation for the entire device during use, preventing equipment shaking during coating and ensuring accuracy. The material trough at the top of the casing stores the coating material needed for easy access by operators, reducing waste and pollution during coating transfer. Two primary motors inside the support plate drive the rollers to rotate, which transport the polycarbonate substrate, achieving automated feeding during the coating process without manual pushing, thus improving efficiency. The lifting plate on one side of the support plate can be height-adjusted through the meshing of a rack and pinion: the secondary motor drives the rotating column and gears to rotate, and the gears mesh with the rack on one side of the lifting plate to move the lifting plate up and down, thereby adjusting the height of the rotating disk and the extrusion rollers on both sides. The extrusion rollers can extrude the surface of the substrate after coating to remove coating bubbles and ensure a smooth coating. During coating, the lifting plate can be raised to place the substrate and extrusion rollers at a comfortable operating height, avoiding the need for the user to bend over or stand on tiptoe. When used with automated coating equipment, the height can be adjusted to match the equipment, ensuring accurate distance between the coating nozzle and the substrate.
[0018] 2. With the adjustment components in place, during use, the limiting plate on one side of the roller can initially restrict the conveying direction of the substrate from both sides, preventing the substrate from shifting laterally. The limiting plate and the adjusting block on one side of the roller provide a sliding base for the adjusting rod. The adjusting rod can move laterally along the adjusting block, thereby adjusting the position of the top-inserted adjusting plate. The rubber pads on both sides of the adjusting plate directly contact the edge of the substrate, which can avoid scratching the surface of the substrate by hard contact and further fix the position through friction. According to the width, the adjusting plate can be inserted along the adjusting rod to adjust the spacing, and then the position can be locked by the positioning screw in the adjusting groove to ensure that the adjusting plate is precisely fitted with the edge of the substrate, preventing deviation, reducing coating waste, and improving the yield.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0028] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0029] 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.
[0030] 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.
[0031] like Figure 1 As shown, this embodiment proposes a polycarbonate surface optical thin film coating support device, including a housing 1, a support component 2 for supporting the optical thin film fixedly installed on the top of the housing 1, and an adjustment component 3 for adjusting the positioning of the optical thin film provided on the housing 1.
[0032] like Figure 2 , Figure 3 and Figure 5As shown, the support assembly 2 includes several support columns 201 fixedly installed at the bottom of the outer shell 1. A feeding trough 202 is opened at the top of the outer shell 1. A support plate 203 is fixedly installed at the top of the outer shell 1. Two first motors 204 are fixedly installed inside the support plate 203. A roller 205 is fixedly installed at the output end of the first motors 204. A lifting plate 206 is fixedly installed on one side of the support plate 203. A rotating disk 207 is fixedly installed on one side of the lifting plate 206. Two extrusion rollers 208 are rotatably installed on one side of the rotating disk 207. The lifting plate 206... A rack 209 is fixedly installed on one side. Two fixing plates 210 are fixedly installed on one side of the support plate 203. A protective shell 211 is fixedly installed on one side of the fixing plate 210. A second motor 212 is fixedly installed on one side of the protective shell 211. A rotating column 213 is fixedly installed at the output end of the second motor 212. A gear 214 is fixedly installed on the periphery of the rotating column 213. The gear 214 meshes with the rack 209. In use, the support column 201 at the bottom of the shell 1 provides a stable foundation for the entire device, preventing the equipment from shaking during the coating process and affecting the coating precision. The top of the outer casing 1 has a material trough 202 that can store the coating required for coating, making it convenient for operators to access at any time and reducing waste and pollution during the coating transfer process. The two first motors 204 inside the support plate 203 drive the roller 205 to rotate. The roller 205 can transport polycarbonate substrate, realizing automated feeding of the coating process without manual pushing, thus improving efficiency. The lifting plate 206 on one side of the support plate 203 can be height adjusted by the meshing of the rack 209 and the gear 214. The second motor 212 drives the rotating column 213 and the gear 214. When rotated, gear 214 meshes with rack 209 on one side of lifting plate 206, driving lifting plate 206 to move up and down, thereby adjusting the height of rotating disk 207 and pressing rollers 208 on both sides. The pressing rollers 208 can press the surface of the substrate after coating to remove coating bubbles and ensure coating smoothness. During coating, lifting plate 206 can be raised to place the substrate and pressing rollers 208 at a comfortable operating height, avoiding the user from bending over or tiptoeing. When used with automated coating equipment, it can be adjusted to the appropriate height for the equipment to ensure accurate distance between coating nozzle and substrate.
[0033] like Figure 7As shown, the adjusting assembly 3 includes a limiting plate 301 fixedly installed on one side of the roller 205. Adjusting blocks 302 are fixedly installed on both the limiting plate 301 and one side of the roller 205. An adjusting rod 303 is slidably installed between the two adjusting blocks 302. An adjusting plate 304 is inserted into the top of the adjusting rod 303. Rubber pads 305 are fixedly installed on both sides of the adjusting plate 304. Several adjusting grooves 306 are formed on one side of the adjusting plate 304. Positioning screws 307 are threaded onto one side of each adjusting groove 306. In use, the limiting plate 301 on one side of the roller 205 can initially restrict the conveying direction of the substrate from both sides, preventing lateral displacement of the substrate. The adjusting block 302 on one side of the disc 301 and roller 205 provides a sliding base for the adjusting rod 303. The adjusting rod 303 can move laterally along the adjusting block 302, thereby adjusting the position of the top-inserted adjusting plate 304. The rubber pads 305 on both sides of the adjusting plate 304 directly contact the edge of the substrate, which can avoid scratching the surface of the substrate by hard contact and further fix the position through friction. According to the width, the adjusting plate 304 can be inserted along the adjusting rod 303 to adjust the spacing, and then the position is locked by the positioning screw 307 in the adjusting groove 306 to ensure that the adjusting plate 304 is precisely attached to the edge of the substrate, preventing deviation, reducing coating waste, and improving the yield.
[0034] like Figure 4 and Figure 5 As shown, a storage rack 4 is fixedly installed on one side of the outer shell 1, and several sliding rods 5 are fixedly installed on one side of the storage rack 4. A storage box 6 is fixedly installed on the top of two sliding rods 5. In use, the storage rack 4 has a multi-layer structure, which can classify and store uncoated polycarbonate films of different specifications, avoiding wrinkles and scratches caused by film stacking and squeezing, and protecting the flatness of the film surface. The storage box 6 can be flexibly pulled out through the sliding rods 5. Operators can quickly take out the film of the corresponding specification according to the coating needs and place it directly on the roller 205 for conveying and coating. There is no need to frequently move the film roll or sort the scattered film, which reduces the film retrieval time and improves the continuity of coating operations. It is especially suitable for batch coating production scenarios.
[0035] like Figure 5 As shown, a fixing rod 7 is fixedly installed on the top of the outer casing 1, and a sunshade 8 is fixedly installed on the top of the fixing rod 7. Several drainage grooves 9 are opened on the top of the sunshade 8. When in use, the sunshade 8 supported by the fixing rod 7 on the top of the outer casing 1 can block direct sunlight. During the optical film coating process, direct sunlight may cause the coating to cure prematurely or cause color difference on the coating surface. The sunshade 8 can effectively avoid this problem. The drainage grooves 9 on the top of the sunshade 8 can drain rainwater and condensate in time in outdoor or humid environments, preventing water from dripping onto the coating area and contaminating the coating. It is suitable for different working environments and ensures the stability of the coating process.
[0036] like Figure 6As shown, a waste trough 10 is provided on one side of the outer casing 1, and a waste box 11 is fixedly installed on the top of the waste trough 10. When in use, the waste trough 10 on one side of the outer casing 1, together with the waste box 11, can collect the waste generated during the coating process, avoid the waste from scattering and polluting the work area, and facilitate subsequent centralized cleaning and recycling, which is in line with the concept of environmentally friendly production and reduces cleaning and maintenance costs.
[0037] like Figure 4 As shown, a shelf 12 is fixedly installed on one side of the outer shell 1, and several partitions 13 are fixedly installed on the top of the shelf 12. When in use, the partitions 13 on the shelf 12 on one side of the outer shell 1 divide the shelf into multiple independent areas, which can be used to classify and place coated semi-finished products, finished product test reports, paint formula documents or operators' personal tools, avoid mixing of items, facilitate management and access, and improve work efficiency and site cleanliness.
[0038] like Figure 7 As shown, an anti-slip pad 14 is fixedly installed at the bottom of the support column 201, and an anti-slip texture 15 is fixedly installed at the bottom of the anti-slip pad 14. The anti-slip texture 15 is made of rubber. During use, the anti-slip pad 14 and the rubber anti-slip texture 15 at the bottom of the support column 201 increase the friction between the device and the ground. Even if the motor vibrates during the coating process or the operator accidentally touches the device, it can prevent the device from sliding and shifting, ensuring that the actions of the roller 205 conveying and the extrusion roller 208 extruding are accurately aligned with the coating position, and avoiding coating deviation caused by equipment displacement.
[0039] Specifically, in use, the support column 201 at the bottom of the outer shell 1 provides a stable foundation for the entire device, preventing equipment shaking during the coating process from affecting accuracy. The material dispensing tank 202 at the top of the outer shell 1 can store the coating material required for coating, making it convenient for operators to access at any time and reducing waste and pollution during the coating transfer process. The two first motors 204 inside the support plate 203 drive the roller 205 to rotate, and the roller 205 can transport the polycarbonate substrate, realizing automated feeding of the coating process without manual pushing, thus improving efficiency. The lifting plate 206 on one side of the support plate 203 can be connected to the rack 209 and gear 214. Height adjustment is achieved through meshing: the second motor 212 drives the rotating column 213 and gear 214 to rotate. The gear 214 meshes with the rack 209 on one side of the lifting plate 206, pushing the lifting plate 206 up and down, thereby adjusting the height of the rotating disk 207 and the two side extrusion rollers 208. The extrusion rollers 208 can extrude on the surface of the substrate after coating to remove coating bubbles and ensure a smooth coating. During coating, the lifting plate 206 can be raised to place the substrate and extrusion rollers 208 at a comfortable operating height, avoiding the user from bending over or tiptoeing. When used with automated coating equipment, the height can be adjusted to match the equipment to ensure accurate distance between the coating nozzle and the substrate (e.g., ...). Figure 2 , Figure 3and Figure 5 As shown), the limiting disc 301 on one side of the roller 205 can initially restrict the conveying direction of the substrate from both sides, preventing the substrate from shifting laterally; the limiting disc 301 and the adjusting block 302 on one side of the roller 205 provide a sliding base for the adjusting rod 303, which can move laterally along the adjusting block 302, thereby adjusting the position of the top-inserted adjusting plate 304. The rubber pads 305 on both sides of the adjusting plate 304 directly contact the edge of the substrate, which can avoid scratching the surface of the substrate by hard contact, and further fix the position through friction. According to the width, the adjusting plate 304 can be inserted along the adjusting rod 303 to adjust the spacing, and then the position is locked by the positioning screw 307 in the adjusting groove 306 to ensure that the adjusting plate 304 is precisely attached to the edge of the substrate, preventing deviation, reducing coating waste, and improving the yield (e.g. Figure 7 (As shown).
[0040] All technical features in this embodiment can be freely combined according to actual needs.
[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
