[0002] In the field of wide application of electronic devices today, glass cover plate is one of the important components, among which the coating technology is particularly key. The traditional glass cover plate mainly provides basic protection and light transmission function before coating treatment. However, in the field of optical performance, ordinary glass has high reflectivity and low transmittance without coating treatment, which not only reduces the display clarity of the screen, but also produces serious reflection phenomenon in the visual environment, making the comfort of the naked eye extremely poor when watching, and the coating technology effectively solves this problem.

[0003] With the improvement of the optical performance requirements of glass cover plate in the fields of consumer electronics and vehicle display, the cleanliness and precision of the coating process become the core factors affecting the yield of products. Therefore, the pre-treatment (film stripping) of glass cover plate before coating becomes more important.

[0004] In the prior art, in order to ensure the cleanliness of the glass, the glass needs to be cleaned, coated and cut before coating, and then the glass is fixed on the coating equipment one by one, and then the surface protective film is peeled off, and the glass is coated. The repeated actions of this feeding process are many, the feeding time is long, and the production efficiency is low. If the glass is not coated before feeding, the problem of glass being polluted again during feeding may occur, such as CN111453429B. SUMMARY

[0011] In some embodiments, the coating jig structure comprises six, the six coating jig structures are arranged at intervals, and the cylindrical surfaces of the six coating jig structures are uniformly distributed on the same circumference.

[0012] According to another aspect of the present application, a glass to be coated is provided, and a method for loading the glass to be coated is also provided.

[0026] All terms used in the present application have the same meaning as understood by those skilled in the art to which the present application belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted to have meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or excessively formalized sense, unless specifically defined here.

[0027] Techniques, methods and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods and devices should be considered as part of the specification.

[0028] As Figures 1 to 5As shown, the coating equipment disclosed by the embodiment one of the present application comprises a coating jig assembly 10, a fixing assembly 20, a stripping assembly 30 and a housing assembly. The coating jig assembly 10 comprises a plurality of coating jig structures 11, the coating jig structure 11 has a cylindrical surface 111, the axes of the cylindrical surfaces 111 of the plurality of coating jig structures 11 coincide, the fixing assembly 20 is located between adjacent coating jig structures 11 and is located on the same circumference as the cylindrical surface 111, the stripping assembly 30 is correspondingly arranged with the fixing assembly 20, and the housing assembly is located outside the coating jig assembly 10, the fixing assembly 20 and the stripping assembly 30.

[0029] The technical scheme of the embodiment one is applied to coat a plurality of glass to be coated after film, without cutting the film, using the film to move the glass to the coating jig assembly 10 at the same time, fixing the film by the fixing assembly 20, and then fixing the glass and the film on the coating jig structure 11 together, so that the loading speed is fast and the production rate is improved; the housing assembly is vacuumized to provide a dust-free environment inside the housing assembly, and then the protective film on the side of the glass to be coated away from the coating jig assembly 10 is separated by the stripping assembly 30. Since the coating jig assembly 10 is located inside the dust-free environment, the surface of the glass to be coated is not easy to be contaminated in the process of uncovering the protective film. The technical scheme of the embodiment one effectively solves the problem that the glass is contaminated in the loading process in the prior art.

[0030] As Figures 1 to 4As shown, in the technical scheme of embodiment one, the fixing assembly 20 comprises a fixing structure 21, the fixing structure 21 is a hollow structure, the fixing structure 21 has a first long hole 211 and a second long hole 212, the first long hole 211 and the second long hole 212 are arranged on the side wall of the fixing structure 21, and the first long hole 211 and the second long hole 212 are parallel to each other. After the film and the glass are moved to the film coating jig structure 11, the film is arranged on the circumferential outer side of the plurality of film coating jig structures 11 and surrounds a circle; the two ends of the film on the side of the glass close to the film coating jig structure 11 are respectively inserted into the inside of the fixing structure 21 from the first long hole 211 and the second long hole 212, and are fixed, the fixing assembly is rotated, the entire film is tightened, and the film and the film coating jig structure 11 are tightly attached together, thereby achieving the effect of fixing the glass. By using this way to fix the glass, a plurality of glasses are located on the same film, and the film does not need to be cut multiple times, thereby reducing the film time; during the feeding process, the film is used to feed multiple glasses at the same time, which is more efficient than the way of individually pasting a single glass, improves the feeding speed, and thus speeds up the entire production process. In the technical scheme of embodiment one, the fixing structure 21 is a hollow cylindrical structure, in the rotating process, the film is continuously wrapped on the outer surface of the fixing structure 21, since the outer wall surface of the hollow cylindrical structure is a cylindrical outer surface, there is no corner, therefore the outer surface of this shape has less damage to the film, at the same time, the film is uniformly stressed, and is not prone to problems such as sudden rupture of the film caused by local stress of the film being too large, and the service life of the film is longer.

[0031] As shown, Figure 4 In the technical scheme of embodiment one, the fixing assembly 20 further comprises a rotating shaft structure 22 and an operating structure 23, the rotating shaft structure 22 is connected with the fixing structure 21, and the operating structure 23 is connected with the rotating shaft structure 22. The film coating jig assembly 10 further comprises an end plate, the rotating shaft structure 22 is rotatably connected with the end plate, the operating structure is rotated by the worker to drive the rotating shaft structure 22 to rotate, thereby realizing control of the rotation of the fixing structure 21. The operating structure 23 is located on the side of the end plate away from the fixing structure 21, and the operating structure 23 is arranged on the outside of the film coating jig assembly 10, thereby effectively reducing the operation difficulty of the worker.

[0032] As shown, Figure 5As shown, in the technical solution of Embodiment 1, the peeling assembly 30 includes a roller structure 31 and a rotary motor structure 32, with the output end of the roller structure 31 connected to the output end of the rotary motor structure 32. The coating equipment also includes a mounting frame assembly, with the roller structure 31 rotatably connected to the mounting frame assembly and the roller structure 31 passing through the mounting frame assembly. After the film on the side of the glass closest to the coating fixture assembly 10 is fixed by the fixing assembly, the inside of the housing assembly is evacuated. Dust and other contaminants inside the housing assembly are removed with the airflow, providing a dust-free environment inside the housing assembly. One end of the film on the side of the glass away from the coating fixture assembly 10 is attached to the roller structure 31. The rotary motor structure 32 is started, driving the roller structure 31 to rotate. At the same time, the drive device controlling the rotation of the coating fixture assembly 10 is started, and the protective film on the side of the glass away from the coating fixture assembly 10 is peeled off, allowing the exposed surface of the glass to be coated. In the technical solution of Embodiment 1, one protective film corresponds to multiple pieces of glass. Therefore, only one operation is required to peel off the protective film. The peeling speed is fast, which further improves production efficiency. At the same time, since the entire peeling process is carried out in a dust-free environment, the glass surface will not be contaminated, and the coating quality is good.

[0033] like Figure 2 As shown, in the technical solution of Embodiment 1, the coating fixture structure 11 includes six structures, which are arranged at intervals. The cylindrical surfaces 111 of the six coating fixture structures 11 are evenly distributed on the same circumference. It should be noted that the cylindrical surfaces 111 of the six coating fixture structures 11 refer to their outer cylindrical surfaces. The six coating fixture structures 11 are evenly distributed. When loading glass, the coating wraps around the outer periphery of the six coating fixture structures 11. As the fixing component 20 fixes the coating, the coating further adheres to the cylindrical surfaces 111 of the six coating fixture structures 11, thereby achieving the fixation of the glass. Because the six coating fixture structures 11 are evenly distributed, the coating is subjected to uniform force during the tensioning process, which makes it less likely for the coating to break due to excessive local tension. Furthermore, because the six coating fixture structures 11 are evenly distributed, the spacing between adjacent glass pieces on the coating can be reasonably set by combining the size, spacing, diameter of the cylindrical surface 111, and glass size of the six coating fixture structures 11. This ensures that when the coating is fixed on the coating fixture assembly 10, the glass is positioned correspondingly to the coating fixture structure 11, thus fixing the glass to the corresponding coating fixture structure 11.

[0034] In the technical scheme of the second embodiment, the coating jig assembly 10 further comprises a first gear structure, the stripping assembly 30 further comprises a second gear structure, and the first gear structure is engaged with the second gear structure, so that only one rotary motor structure 32 and driving device for controlling the rotation of the coating jig assembly 10 are needed, thereby further reducing the operation steps, lowering the operation difficulty, and reducing the cost.

[0035] As shown in Figures 1 to 6 According to another aspect of the present application, a glass to be coated feeding method is also provided, which adopts the coating device described above and comprises the following steps: covering the first protective film 001 and the second protective film 002 on the upper and lower surfaces of the glass respectively; transferring multiple glasses to the coating device at the same time by using the second protective film 002; connecting the second protective film 002 with the fixing assembly 20, and fixing the second protective film 002 on the coating jig assembly 10 by the fixing assembly 20; stripping the first protective film 001 by using the stripping assembly 30.

[0036] The first protective film 001 is the protective film on the side of the glass away from the coating jig assembly 10, and the second protective film 002 is the protective film on the side of the glass close to the coating jig assembly 10. The first protective film 001 and the second protective film 002 are coated by the film coating device shown in Figure 6 During the coating process, there are multiple glasses between each first protective film 001 and second protective film 002, so that multiple glasses can be fed at the same time by using the second protective film 002, thereby improving the feeding efficiency. After the first end of the second protective film 002 passes through the first long hole 211 and is fixed on the fixing structure 21, the second end of the second protective film 002 passes through the second long hole 212 and is fixed on the fixing structure 21 along the outer side of the multiple coating jig structures 11, so that the multiple glasses are arranged correspondingly with the multiple coating jig structures 11, and the fixing structure 21 is rotated to tighten the second protective film 002 tightly around the outside of the coating jig structure 11, thereby ensuring the relative position between the glass and the coating jig structure 11.

[0037] In the technical scheme of the present application, the surface of the second protective film 002 has adhesion, and the adhesion of the second protective film 002 is greater than 20g. The glass is fixed on the surface of the second protective film 002 by adhesion, and the second protective film 002 is connected with the fixing assembly 20 by adhesion. When the adhesion of the second protective film 002 is less than 20g, the glass is prone to fall off, and the second protective film 002 is prone to be separated from the fixing assembly 20.

[0038] In the technical solution of the present application, the length of the second protective film 002 is greater than the total length of the plurality of cylindrical surfaces 111 of the plurality of film coating jig structures 11. This makes the second protective film 002 still have a surplus to be connected with the fixing assembly 20 after being arranged around the plurality of film coating jig structures 11 for one turn.

[0039] 400mm < L-2πr < 600mm; L is the length of the second protective film 002; R is the radius of the cylindrical surface 111; When L-2πr is less than 400mm, the problem that the second protective film 002 cannot be connected with the fixing assembly 20 after being arranged around the plurality of film coating jig structures 11 for one turn is prone to occur; when L-2πr is greater than 600mm, the problem that the second protective film 002 has a large surplus after being arranged around the plurality of film coating jig structures 11 for one turn, which causes the glass to easily slide down under the action of gravity and drive the second protective film 002 to slide down is prone to occur.

[0040] In the technical solution of the present application, the second protective film 002 is connected with the fixing assembly 20 in a bonding manner. Since the second protective film 002 itself has adhesion, the connection between the second protective film and the fixing assembly 20 can be realized by using the adhesion of the second protective film 002. In the process of rotating the fixing assembly 20, the second protective film 002 is not easy to fall off.

[0041] In the technical solution of the present application, the inside of the shell assembly is a vacuum environment before the first protective film 001 is uncovered. By means of vacuumizing, a dust-free environment can be provided for the inside of the shell assembly, which avoids dust from falling on the surface of the glass after the film is uncovered, and at the same time provides the required environment for glass film coating.

[0042] As can be known from the above, the device of the application is composed of three main parts: product film coating integration, rotary fixed locking device (fixed assembly 20), and negative pressure stripping device (stripping assembly 30). The product film coating integration is a preparation action before coating. Before coating, the glass cover plate needs to have a high cleanliness on the product surface, so dust-free operation is particularly important, which will directly affect the yield and output of the product. Product cleaning and film coating are important processes before coating of the glass cover plate. The purpose of cleaning is to improve the cleanliness of the product and remove surface dirt and impurities. Film coating is to protect and maintain the cleanliness of the product after cleaning. The cleaning process of the application is carried out in a conventional manner. After cleaning by the cleaning machine, the product is transferred to the film coating machine by manual operation. Film coating operation needs to connect multiple products in series to form a whole. The products are connected to each other. The series connection of the products not only saves the cutting action, but also ensures the continuity of the operation, and the production efficiency is improved by 50% compared with the original single cutting method. The bottom film (second protective film 002) applied to the film coating integration requires: high temperature resistance, certain adhesion, and reference adhesion ≥20g. The role of the bottom film is to connect the product back with its own adhesion to fix the product. The upper protective film (first protective film 001) requires: high cleanliness, no dirt and impurities, and no wrinkles after film coating. Its role is to protect the cleanliness of the product before coating. The number of integrated films of different types of products varies due to the size difference of the products. The products need to be evenly arranged in the corresponding effective area. The width of the film material is matched with the effective height of the equipment. For example, if the effective width of the coating jig is 1160mm, the film material with a width of 1200mm is relatively reasonable, and 20mm is left as a margin on both ends. The upper and lower margins are also considered to make it easier to place the product after cleaning by manual film coating operation. The length of the film material is equivalent to the circumference of the coating jig, and 400mm is added to the circumference for the rotation of the fixing device. Formula: L=2πr+400, “L” is the total length of the film material, and “r” is the radius of the coating jig. After verifying the length and width of the film material, the corresponding area of the effective area is obtained, and the product only needs to be reasonably arranged in the corresponding unit area to realize normal coating. The clean product after cleaning and film coating is transferred to the coating operation area by a special turnover vehicle and waits for the film to be placed. Before placing the product, the operator needs to separate the bottom film and the upper protective film at the head and tail of the film coated product to facilitate the smooth connection of the upper and lower films with the respective devices during the film placement. When the film is placed on the coating equipment, the product is laid flat on the surface of the coating jig, and the separated bottom film at the head and tail is inserted into the fixing device. The fixing device (fixed assembly 20) of the application is not locked, and the product will slide down due to its own gravity, so a small amount of adhesive tape can be used to assist in fixing during the film placement process to avoid product falling and causing defects. The fixing device is in the shape of a cylinder, and the components are longitudinally processed with two through-hole gaps as two film entrances for the head and tail of the bottom film.After the bottom film head and tail are inserted into the fixing device, the film is tensioned and locked by manually rotating the device with a crank tool, so that the bottom film is perfectly attached to the fixture, and the product is fixed. The upper piece mode of the application adopts integrated operation, which has a significant improvement in time efficiency compared to the original single piece mode. The upper piece mode of the application shortens the piece operation time, reduces the workload of employees, and saves the corresponding consumables for pasting products, perfectly achieving cost reduction and efficiency improvement. After the upper protective film is pasted on the surface of the film receiving shaft of the peeling device, the upper protective film peeling device operates in a vacuum negative pressure environment. A dust-free environment is better, and the product cleanliness is better. The yield is higher. When the upper protective film is well adhered to the peeling shaft (roller shaft structure 31), the chamber door of the equipment can be closed for exhaust action. Start the exhaust system, and when the vacuum negative pressure reaches the set value, the program automatically starts the peeling device (peeling assembly 30) and the plating fixture rotating motor, and then completes the peeling and recycling of the upper protective film. Peeling the upper protective film in a vacuum negative pressure environment not only greatly reduces the pollution of dust points on the product surface after peeling in the original atmospheric environment, but also effectively optimizes and cancels the manual peeling of the protective film and the peeling operation time, and the efficiency is significantly improved. After the upper protective film is removed, the product plating surface is exposed to the vacuum environment of the plating equipment and waits for plating. When the chamber vacuum reaches the plating set value, automatic plating can be started.
