[0022] 1.

In this process, the chambers for coating the optical film and the anti-fouling film are relatively independent, which ensures the coating effect while avoiding cross-contamination when coating the optical film and the anti-fouling film, thereby improving the appearance yield of the coated products.

[0023] 2. Since the material loading and unloading chamber is connected with the first film-forming chamber, the interaction chamber or the second film-forming chamber, when the coating device is working, the material can be loaded into the coating device through the material loading and unloading chamber, and when the product to be coated is coated in the coating device, the material can be unloaded through the material loading and unloading chamber.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] Combination Figures 1 to 8 As shown, the coating equipment provided in this embodiment is used to coat the product 10. Specifically, the coating equipment includes a coating device 100 and a feeding and discharging device 200. The coating device 100 includes a first film forming mechanism, an interactive mechanism and a second film forming mechanism. The first film forming mechanism includes a first film forming chamber 111, the interactive mechanism includes an interactive chamber 121, and the second film forming mechanism includes a second film forming chamber 131. The interactive chamber 121 is connected to the first film forming chamber 111 and the second film forming chamber 131; the feeding and discharging device 200 includes an feeding and discharging chamber 210, and the feeding and discharging chamber 210 is connected to the interactive chamber 121, or the feeding and discharging chamber 210 is connected to the first film forming chamber 111, or the feeding and discharging chamber 210 is connected to the second film forming chamber 131, which can be used to load materials into and discharge materials from the coating device 100.

[0041] Since the coating device 100 is provided with a first film forming mechanism and a second film forming mechanism, when coating the product 10 to be coated, different film layers on one side or both sides of the product 10 to be coated can be coated in different film forming mechanisms according to actual conditions or needs, thereby avoiding cross contamination during the coating process. If only both sides of the product 10 are coated with an optical film, the optical film coating operation on the first side of the product 10 can be completed in the first film forming mechanism, and then the optical film coating operation on the second side of the product 10 can be completed in the second film forming mechanism. In this process, the first film forming mechanism and the second film forming mechanism cooperate to complete the double-sided coating, and there is no need to reverse the product 10, thereby improving the coating efficiency; if both sides of the product 10 are coated with an optical film and an anti-fouling film is coated in addition to the optical film of the product 10, the optical film coating operation on both sides of the product 10 can be completed in the first film forming mechanism or the second film forming mechanism, and then the product 10 coated with the optical film can be transported to the second film forming mechanism or the first film forming mechanism to complete the anti-fouling film coating operation on the product 10 coated with the optical film. In this process, the chambers for coating the optical film and the anti-fouling film are relatively independent, which ensures the coating effect while avoiding cross-contamination when coating the optical film and the anti-fouling film, thereby improving the appearance yield of the coated product 10.

[0042] Since the material loading and unloading chamber 210 is connected with the first film forming chamber 111, the interaction chamber 121 or the second film forming chamber 131, when the coating device 100 is working, the material can be loaded into the coating device 100 through the material loading and unloading chamber 210, and after the product 10 to be coated is coated in the coating device 100, the material can be unloaded through the material loading and unloading chamber 210. That is, one material loading and unloading chamber 210 can meet the working requirements of loading and unloading at the same time, and there is no need to set up a separate unloading chamber and a material loading chamber, which can reduce the setting of one chamber, thereby reducing the production cost of the coating equipment.

[0043] Specific, combined Figure 1As shown, when the material input and output chamber 210 is configured to be connected to the first film forming chamber 111; if only an optical film is coated on the product 10 and no anti-fouling film is coated, for example, the product 10 to be coated enters the first film forming chamber 111 through the material input and output chamber 210, and after the first surface of the product 10 to be coated is subjected to the first optical film forming in the first film forming chamber 111, the interactive mechanism grabs the semi-coated product 10 in the first film forming chamber 111 and rotates it 180°, and transfers the semi-coated product 10 in the first film forming chamber 111 to the second film forming chamber 131, and the first surface of the semi-coated product 10 is subjected to the second optical film forming in the second film forming chamber 131, and then the interactive mechanism grabs the finished product in the second film forming chamber 131 and rotates it 180° again, and transfers the processed coated finished product back to the first film forming chamber 111, and the coated product 10 is discharged from the material input and output chamber 210, thereby completing the coating of the product 10 once. If an optical film is coated on both sides of the product 10, and an anti-fouling film is coated on the product 10 in addition to the optical film, illustratively, the product 10 to be coated enters the first film forming chamber 111 through the feed and discharge chamber 210, the interactive mechanism grabs the product 10 to be coated in the first film forming chamber 111 and rotates it 180°, and transfers the product 10 to be coated in the first film forming chamber 111 to the second film forming chamber 131. After the double-sided optical film is coated on the product 10 to be coated in the second film forming chamber 131, the interactive mechanism grabs the product 10 coated with the optical film in the second film forming chamber 131 and rotates it 180° again, and transfers the product 10 coated with the optical film back to the first film forming chamber 111. The product 10 coated with the optical film is coated with an anti-fouling film in the first film forming chamber 111, and then directly enters the feed and discharge chamber 210 from the first film forming chamber 111, and discharges the material from the feed and discharge chamber 210, thereby completing the coating of the product 10 once.

[0044] Combination Figure 2As shown, when the material-in-and-out chamber 210 is configured to be connected to the interaction chamber 121; if only an optical film is to be coated on the product 10 and no antifouling film is to be coated, illustratively, the product 10 to be coated enters the interaction chamber 121 through the material-in-and-out chamber 210, the interaction mechanism grabs the product 10 to be coated in the interaction chamber 121 and rotates it 90°, and transfers the product 10 to be coated in the interaction chamber 121 to the first film-forming chamber 111, and the first surface of the product 10 to be coated is subjected to the first optical film coating in the first film-forming chamber 111. The interactive mechanism grabs the semi-coated product 10 in the first film forming chamber 111 and rotates it 180°, and transfers the semi-coated product 10 in the first film forming chamber 111 to the second film forming chamber 131. The first surface of the semi-coated product 10 is coated with the second optical film in the second film forming chamber 131. Then, the interactive mechanism rotates 90° again to transfer the coated product 10 in the second film forming chamber 131 to the feed and discharge chamber 210. The coated product 10 is discharged from the feed and discharge chamber 210, thereby completing the coating of the product 10. If an optical film is to be coated on both sides of the product 10, and an antifouling film is coated on the outside of the optical film of the product 10, for example, the product 10 to be coated enters the interaction chamber 121 through the material inlet and outlet chamber 210, the interaction mechanism grabs the product 10 to be coated in the first film forming chamber 111 and rotates 90 degrees, and transfers the product 10 to be coated in the interaction chamber 121 to the second film forming chamber 131. After the product 10 to be coated is coated with the optical film on both sides in the second film forming chamber 131, the interaction mechanism grabs the product 10 in the second film forming chamber 131. The product 10 coated with the optical film is rotated 180° again, and the product 10 coated with the optical film is transferred back to the first film forming chamber 111. The product 10 coated with the optical film is coated with an anti-fouling film in the first film forming chamber 111. Then, the interactive mechanism grabs the coated finished product in the first film forming chamber 111 and rotates 90° again, and transfers the coated finished product in the first film forming chamber 111 to the interactive chamber 121. The product 10 enters the material loading and unloading chamber 210 from the interactive chamber 121 and is discharged from the material loading and unloading chamber 210, thereby completing the coating of the product 10. In other embodiments, in order to improve the coating efficiency, during the coating process in the first film forming chamber 111, the interactive mechanism can transfer another batch of coated products 10 in the second film forming chamber 131 to the material loading and unloading chamber 210; during the coating process in the second film forming chamber 131, the interactive mechanism can transfer another batch of products 10 to be coated to the first film forming chamber 111 through the material loading and unloading chamber 210.

[0045] Combination Figure 3As shown, when the material loading and unloading chamber 210 is configured to be connected to the second film forming chamber 131; if only an optical film is to be coated on the product 10 and no antifouling film is to be coated, illustratively, the product 10 to be coated enters the second film forming chamber 131 through the material loading and unloading chamber 210, the interactive mechanism grabs the product 10 to be coated in the second film forming chamber 131 and rotates 180°, and transfers the product 10 to be coated in the second film forming chamber 131 to the first film forming chamber 111, and the first surface of the product 10 to be coated is placed in the first film forming chamber. After the first optical film is formed in the film forming chamber 111, the interactive mechanism grabs the semi-coated product 10 in the first film forming chamber 111 and rotates it 180° again, and transfers the semi-coated product 10 in the first film forming chamber 111 back to the second film forming chamber 131, and completes the coating of the second optical film on the first surface of the semi-coated product 10 in the second film forming chamber 131. After that, the coated product 10 is directly discharged from the feed and discharge chamber 210, thereby completing the coating of the product 10 once. If an optical film is coated on both sides of the product 10, and an anti-fouling film is coated on the optical film of the product 10, illustratively, the product 10 to be coated enters the second film forming chamber 131 through the loading and unloading chamber 210, and after the product 10 to be coated has been optically filmed on both sides in the second film forming chamber 131, the interactive mechanism grabs the product 10 coated with the optical film in the second film forming chamber 131 and rotates it 180°, and transfers the product 10 coated with the optical film to the first film forming chamber 111, and the anti-fouling film is coated on the product 10 coated with the optical film in the first film forming chamber 111, and then the product 10 to be coated in the first film forming chamber 111 is grabbed from the interactive mechanism and rotated 180°, and the coated finished product in the first film forming chamber 111 is transferred to the second film forming chamber 131, and the coated finished product enters the loading and unloading chamber 210 from the second film forming chamber 131 and is discharged from the loading and unloading chamber 210, thereby completing the coating of the product 10 once.

[0046] In addition, in order to further improve the coating efficiency, when only the optical film is coated on the product 10 without the antifouling film, when the coating on the first side of the product 10 is completed and the coating on the second side begins, the material loading and unloading chamber 210 immediately feeds into the coating device 100; when the optical film is coated on both sides of the product 10 and the antifouling film is coated in addition to the optical film of the product 10, when the double-sided coating of the product 10 is completed and the antifouling film coating operation begins, the material loading and unloading chamber 210 immediately feeds into the coating device 100.

[0047] In addition, when the material inlet and outlet chamber 210 is connected to the coating device 100, the material inlet and outlet of the material inlet and outlet chamber 210 can be set in any direction according to actual needs.

[0048] Preferably, the coating device 100 further includes two first valves (not shown in the figure), which are arranged between the interaction chamber 121 and the first film forming chamber 111, and between the interaction chamber 121 and the second film forming chamber 131; the two first valves are in a normally open state in the working state, so as to facilitate the normal progress of the coating process. Preferably, the first valves can be selectively opened.

[0049] The material input and output device 200 further includes a second valve (not shown in the figure), which is disposed between the material input and output chamber 210 and the coating device 100, and the second valve can be selectively opened.

[0050] Specifically, when the material input and output chamber 210 feeds material into the coating device 100, the second valve is opened to ensure smooth feeding; after the material input and output chamber 210 has finished feeding material into the coating device 100, the second valve is closed to prevent foreign matter from entering the coating device 100 and affecting the coating effect, thereby further improving the appearance yield of the coated product 10.

[0051] Preferably, the feeding and discharging device 200 also includes a lifting mechanism, which includes a lifting chamber 221 and a lifting assembly 222; the feeding and discharging chamber 210 is connected to the coating device 100 through the lifting chamber 221, and the lifting assembly 222 is arranged in the lifting chamber 221. The lifting assembly 222 can grab the product 10 to complete the interaction between the feeding and discharging chamber 210 and the coating device 100.

[0052] Since the lifting chamber 221 is arranged between the material loading and unloading chamber 210 and the coating device 100, and is connected to both the material loading and unloading chamber 210 and the coating device 100, and the lifting component 222 arranged in the lifting chamber 221 can grab and transport the product 10 to realize the interaction between the material loading and unloading chamber 210 and the coating device 100, thereby solving the problem of height difference between the material loading and unloading chamber 210 and the coating device 100, and at the same time can improve the convenience and coating efficiency during coating.

[0053] Furthermore, the lifting component 222 includes a lifting mechanical arm 2221, a lifting component 2222 and a pushing component 2223. The lifting component 2222 is connected to the lifting mechanical arm 2221 to drive the lifting mechanical arm 2221 to rise and fall, and the pushing component 2223 is connected to the lifting mechanical arm 2221 to drive the lifting mechanical arm 2221 to extend and retract.

[0054] The lifting mechanical arm 2221 is provided with a clamping claw, which is used to clamp the product 10 to complete the interaction of the product 10 between the material input and output chamber 210 and the coating device 100; the lifting component 2222 drives the clamping claw to rise and fall in the height direction to correspondingly realize the interaction of the product 10 between the material input and output chamber 210 and the lifting chamber 221; the pushing component 2223 is used to drive the clamping claw to translate in the horizontal direction to correspondingly realize the interaction of the product 10 between the lifting chamber 221 and the coating device 100. The specific structures of the lifting mechanical arm 2221, the lifting component 2222 and the pushing component 2223 can refer to the existing structural settings, and this application does not make specific limitations.

[0055] Preferably, the interactive mechanism further includes an interactive component 122 , and the interactive component 122 includes an interactive mechanical arm 1221 and an interactive rotating member 1222 , the interactive rotating member 1222 is movably disposed in the interactive chamber 121 , and the interactive mechanical arm 1221 is connected to the interactive rotating member 1222 .

[0056] Taking the transfer of the product 10 in the first film forming chamber 111 to the second film forming chamber 131 as an example, after the interactive robot 1221 grabs the product 10 in the first film forming chamber 111, the interactive rotating part 1222 starts to rotate relative to the interactive chamber 121, thereby driving the interactive robot 1221 to rotate. After the interactive robot 1221 that has grabbed the product 10 is turned to the second film forming chamber 131, the interactive rotating part 1222 stops rotating, and the interactive robot 1221 transfers the grabbed product 10 to the second film forming chamber 131, thereby completing a product 10 interaction between the first film forming chamber 111 and the second film forming chamber 131.

[0057] In some other embodiments, the interactive component 122 can also be configured as an interactive robot arm 1221 and an interactive translation member, wherein the interactive robot arm 1221 is connected to the interactive translation member, and the interactive translation member drives the interactive robot arm 1221 to translate in the interactive chamber 121 along the direction from the first film forming chamber 111 to the second film forming chamber 131, so that the interactive robot arm 1221 grabs the product 10 in the first film forming chamber 111 and interacts with the second film forming chamber 131.

[0058] Furthermore, the interactive component 122 also includes an interactive telescopic member 1223 and an interactive lifting member 1224 . The interactive telescopic member 1223 is connected to the interactive rotating member 1222 , and the interactive mechanical arm 1221 is connected to the interactive telescopic member 1223 via the interactive lifting member 1224 .

[0059] The interactive component 122 includes at least two interactive mechanical arms 1221, and the two interactive mechanical arms 1221 are arranged at intervals along the circumference of the interactive rotating member 1222. The number of interactive telescopic members 1223 and interactive lifting members 1224 is arranged corresponding to the interactive mechanical arms 1221. When transportation is required, one clamping claw clamps the film-formed product 10 from the first film-forming chamber 111, and the other clamping claw clamps a piece of film-out product 10 from the second film-forming chamber 131. After the clamping is completed, the two interactive mechanical arms 1221 are retracted into the interactive chamber 121 through the corresponding interactive telescopic members 1223, and then the interactive rotating member 1222 rotates to complete the interaction of the product 10. During the interaction process, since the interactive mechanical arms 1221 retract under the drive of the corresponding interactive telescopic members 1223, the rotation radius of the entire interactive component 122 can be reduced, thereby saving space in the interactive chamber 121. Since it is difficult to ensure that the centers of the first film forming chamber 111, the second film forming chamber 131 and the interaction chamber 121 are on the same straight line in actual processing and assembly, in order to improve the convenience and accuracy when taking and placing the product 10, the interactive robot arm 1221 is connected to the interactive telescopic member 1223 through the interactive lifting member 1224. During the interaction process, according to the height difference between the first film forming chamber 111 and the interaction chamber 121, and between the interaction chamber 121 and the second film forming chamber 131, the interactive lifting member 1224 drives the corresponding interactive robot arm 1221 to rise and fall adaptively, so as to accurately and quickly complete the interaction of the product 10. The specific structure of the interactive telescopic member 1223 and the interactive lifting member 1224 can refer to the existing structural settings, and this application does not make specific limitations. It can be understood that as long as the interactive mechanism can realize the transportation of the coated product 10 between the feeding and discharging chamber 210, the first film forming chamber 111 and the second film forming chamber 131, its specific structure is not limited to the aforementioned embodiment.

[0060] Preferably, the second film forming mechanism includes a coating mechanism 132, which is arranged in the second film forming chamber 131, including a rotating frame 1321, a telescopic driving assembly 1322 and a plurality of protective members 1323; a plurality of mounting positions 1301 for mounting the product 10 to be coated are arranged on the rotating frame 1321 along its radial intervals, and the plurality of protective members 1323 are arranged one by one corresponding to the plurality of mounting positions 1301, and the telescopic driving assembly 1322 is transmission-connected to the plurality of protective members 1323, and the telescopic driving assembly 1322 drives the protective members 1323 to rotate along the radial direction of the rotating frame 1321, so that the protective members 1323 can protect the product 10 to be coated.

[0061] In this embodiment, the protective member 1323 is configured as an open shell. During processing, the product 10 to be coated is first installed on the mounting position 1301 of the rotating frame 1321. The telescopic driving assembly 1322 drives the protective member 1323 to move radially outward along the rotating frame 1321, so that the open end of the protective member 1323 can cover the product 10 to be coated on the side of the axis of the rotating frame 1321. When the outer side of the product 10 to be coated is coated, the protective member 1323 can protect the inner side of the product 10 to be coated, prevent the inner side of the product 10 to be coated from being affected by the coating process, and improve the qualified rate of the product 10. Then the telescopic drive assembly 1322 drives the protective member 1323 to move radially inward along the rotating frame 1321, so that the protective member 1323 is separated from the product 10 to be coated. At this time, the protective member 1323 does not interfere with the movement of the product 10 to be coated, and can allow the product 10 to be coated to be turned over, so as to facilitate double-sided continuous coating; the telescopic drive assembly 1322 drives the protective member 1323 to move radially outward along the rotating frame 1321, so that the protective member 1323 is again covered on the side of the axis of the product 10 to be coated close to the rotating frame 1321, so as to achieve coating on the other side of the product 10 to be coated. It is achieved that the inner side of the product 10 to be coated is completely covered during coating, the coating quality and coating pass rate of the product 10 are improved, and at the same time, when the product 10 to be coated is turned over, it can avoid it without affecting its turning over. The turning over of the mounting position 1301 is achieved by the turning mechanism 135, and the turning mechanism 135 can adopt the existing technology. The specific structure and principle of the turning mechanism 135 are not described in detail in this application.

[0062] Furthermore, the coating mechanism 132 further includes a plurality of connection components 1324, the telescopic drive component 1322 is provided with a plurality of output shafts, the plurality of protection components 1323 are connected to the plurality of connection components 1324 one by one, and the plurality of connection components 1324 are transmission-connected to the corresponding output shafts. The protection components 1323 are connected to the corresponding output shafts through the corresponding connection components 1324, so that the protection components 1323 are rotated with the telescopic drive component 1322, and the interference between the protection components 1323 and the output shaft is avoided.

[0063] Further, the connecting assembly 1324 includes a first connecting member 1341, a second connecting member 1342 and a third connecting member 1343, wherein the first connecting member 1341 is connected to the output shaft, the second connecting member 1342 is connected to the protective member 1323, and the third connecting member 1343 is connected to both the first connecting member 1341 and the second connecting member 1342. The third connecting member 1343 is configured as a rod, and a plurality of guide channels 1302 extending radially thereof are provided on the rotating frame 1321, and the third connecting member 1343 is slidably connected to the corresponding guide channels 1302, and the guide channels 1302 guide the corresponding third connecting member 1343, thereby improving the accuracy of the connecting assembly 1324 in driving the protective member 1323 to move.

[0064] Furthermore, the connection assembly 1324 also includes a dislocation member 1344, which is arranged between the second connection member 1342 and the third connection member 1343. A buffer shaft is arranged between the second connection member 1342 and the third connection member 1343, one end of the buffer shaft is fixedly connected to the second connection member 1342, and the other end passes through the third connection member 1343 and is slidably connected to the third connection member 1343; the dislocation member 1344 is arranged as a spring, and the spring is sleeved on the buffer shaft. When the protective member 1323 is attached to the product 10 to be coated, the spring is in a compressed state, and the spring applies elastic force to the protective member 1323, so that the protective member 1323 is more closely attached to the product 10 to be coated, thereby improving the protective effect. The length of the spring in each group of connecting components 1324 is set according to actual needs. When the telescopic drive component 1322 drives the protective part 1323 to retract, the spring first returns to its original length, and the protective part 1323 moves toward the axis of the rotating frame 1321. Since the original lengths of adjacent springs along the circumference of the rotating frame 1321 are different, when the protective parts 1323 are retracted, misalignment can be achieved between adjacent protective parts 1323, thereby avoiding collision and interference between adjacent protective parts 1323 when they are retracted, thereby improving the smoothness of operation.
