Description

Technical Field

[0001] This invention relates to the field of film application equipment technology, and in particular to an integrated device for film peeling, film application, and hot-pressing bonding. Background Technology

[0002] With the rapid development of display technology, LED screens, due to their advantages such as high brightness, high contrast, and long lifespan, are widely used in commercial displays, indoor and outdoor advertising, stage rentals, and other fields. During the production and assembly of LED screens, to prevent scratches, contamination, or impact damage to the screen surface during transportation, installation, and use, a special optical protective film (LED protective film) is usually applied to the LED screen surface. This protective film generally possesses properties such as high light transmittance, scratch resistance, and anti-static properties, and has a protective film on both its upper and lower surfaces to prevent contamination or damage during storage and handling.

[0003] Currently, the industry's process for applying protective films to LED screens mainly includes the following steps: First, the protective film on the lower surface of the screen is removed; then, the protective film is adhered to the LED screen surface; next, a vacuum process is used to ensure full adhesion between the film layer and the screen and to remove air bubbles; finally, the protective film on the upper surface of the screen is removed. However, most existing film-applying equipment can only complete one or some of these steps. For example, some equipment can only automatically pick up, place, and apply the protective film; some are dedicated to vacuum degassing; and others are only used to complete the final surface film removal. This means that the entire film-applying process often requires multiple machines working together, and the operation of multiple machines can lead to the following problems: Firstly, because the equipment for each process is independent, the LED screen needs to be moved and positioned multiple times between different workstations, resulting in a long production cycle and low overall film application efficiency. Secondly, the connection between processes relies on simple mechanical transfer, which easily causes screen bumps, film contamination, or displacement, affecting the final film application quality. Therefore, an integrated film peeling, film application, and hot-pressing lamination device is provided to solve the above technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated device for film peeling, film application, and hot-pressing lamination, addressing the shortcomings of existing technologies, and solving the technical problem that existing film application equipment cannot simultaneously perform the film peeling, film application, and hot-pressing lamination processes.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: An integrated device for peeling, applying, and hot-pressing LED protective film includes an application mechanism for applying LED protective film to the surface of an LED screen, a vacuum hot-pressing mechanism for degassing the LED protective film on the surface of the LED screen, and a peeling mechanism for peeling the LED protective film after vacuum hot-pressing. The film application mechanism includes a first support platform, which is equipped with a first support frame and a storage component for storing stacked LED protective films. The first support frame is equipped with a lifting seat that can move laterally and vertically, and the lifting seat is equipped with a material-picking component for picking up individual LED protective films. It also includes a first transport component for continuously transporting the LED screen. The first support frame is equipped with a movable frame that can move laterally and vertically, and the movable frame is equipped with a handling fixture for gripping the LED screen. The first support platform is equipped with a material transport platform that can move laterally and transport the LED screen. The initial end of the material transport platform's movement trajectory is connected to the end of the lateral movement trajectory of the handling fixture, and the end of the material transport platform's movement trajectory is connected to the end of the lateral movement trajectory of the material-picking component. The vacuum hot pressing mechanism includes a second support platform and multiple vacuum hot pressing modules mounted on the second support platform. Each vacuum hot pressing module includes an upper sealing frame and a lower sealing frame arranged vertically, and a transverse sliding plate slidably mounted on the second support platform. The lower sealing frame is movably mounted on the transverse sliding plate. The interior of the upper sealing frame is equipped with multiple hot pressing components for hot pressing LED screens with LED protective films. A vacuum tube is connected to the edge of the lower sealing frame.

[0006] The beneficial effects of this invention are: 1. By controlling the up-and-down and lateral movements of the movable frame and cooperating with the handling fixture, the LED screen transported to the end of the first transport component can be moved to the material handling platform. Then, the material handling platform carrying the LED screen is controlled to move laterally to the end of the trajectory of the material handling component. At this time, the LED screen on the material handling platform is placed at the film application station. Then, the lifting seat is controlled to move laterally and up-and-down, cooperating with the material handling component to pick up the LED protective film placed on the top of the storage component. After being picked up, the LED protective film is transported to the LED screen at the film application station for film application, thus realizing the feeding of LED protective film and automatic film application.

[0007] With the cooperation of the aforementioned institutions, automatic feeding of LED screen materials, automatic feeding of LED protective film, and automatic film application are achieved. The entire process is automated and requires no staff intervention, thus improving the efficiency of LED screen film application.

[0008] 2. After the film-applying mechanism applies the LED protective film to the LED screen, the lower sealing frame is positioned at its lowest point and separated from the upper sealing frame. At this time, the transverse plate is controlled to slide laterally on the second support platform. After sliding until the lower sealing frame is offset from directly below the upper sealing frame, the LED screen to be vacuum-heat-pressed on the conveying platform can be transported into the lower sealing frame. Then, the transverse plate is controlled to slide laterally back to its original position, so that the lower sealing frame, carrying the LED screen to be vacuum-heat-pressed, moves to be positioned directly below the upper sealing frame. Then, the lower sealing frame is controlled to move upward to its highest point, and the upper and lower sealing frames are in a closed state, forming a sealed chamber inside the upper and lower sealing frames. The LED screen to be vacuum-heat-pressed is placed in the sealed chamber.

[0009] By removing air from the sealed chamber through a vacuum tube, the LED protective film on the surface of the LED screen is placed under vacuum negative pressure. Under negative pressure, the LED protective film will be compressed and deformed, thereby compressing out the air bubbles inside the LED protective film, eliminating residual air bubbles, achieving debubbling treatment, and improving the quality of the LED screen after film application.

[0010] 3. While performing vacuum degassing on the LED protective film on the LED screen surface, a hot-pressing component is operated to heat the LED protective film to 120 degrees Celsius or higher, softening it. Once softened, the LED protective film becomes adhesive. Pressure is applied to the softened film, and after pressing for 60 minutes, it is pressed firmly onto the LED screen surface. Through these steps, vacuum and hot-pressing of the LED protective film are achieved, all in a fully automated process requiring no operator intervention, thus improving efficiency and safety. The combined effect of vacuum and hot-pressing not only effectively eliminates air bubbles, but also ensures that the LED protective film remains firmly attached to the LED screen surface even after returning to normal pressure and temperature, without the formation of new bubbles or detachment.

[0011] 4. After the LED protective film on the LED screen surface undergoes vacuum hot-press degassing, the LED screen film application process is complete. Finally, the LED screens, after vacuum hot-press degassing, are individually transported from the lower sealed frame to the film-peeling mechanism, which peels off the protective film from the upper surface of the LED screen. Through the coordinated action of the film application mechanism, the vacuum hot-press mechanism, and the film-peeling mechanism, the LED screens undergo sequential film application, vacuum hot-press degassing, and film peeling processes. These processes are fully automated, requiring no operator intervention, significantly improving the production efficiency of LED screens. Attached Figure Description

[0029] The following is a detailed description of an integrated device for film peeling, film application, and hot-pressing bonding according to the present invention, with reference to the accompanying drawings.

[0030] like Figure 1 As shown, an embodiment of the integrated film-peeling, film-applying, and hot-pressing bonding device of the present invention includes a film-applying mechanism 1 for applying an LED protective film to the surface of an LED screen, a vacuum hot-pressing mechanism 2 for vacuum hot-pressing and degassing the LED protective film on the surface of the LED screen, and a film-peeling mechanism 3 for peeling off the LED protective film after vacuum hot-pressing. Specifically, when the LED protective film is an independent product, a protective film is attached to both its upper and lower surfaces. Before applying the LED protective film to the surface of the LED screen, the protective film on the lower surface of the LED protective film must be peeled off first before the LED protective film can be applied to the LED screen. By operating the film-applying mechanism 1, the protective film on the lower surface of the LED protective film is first peeled off, and then the LED protective film is applied to the LED screen, completing the pre-applying process. Subsequently, the LED screens with the applied LED protective film are transported to the vacuum hot-pressing mechanism 2. Once a sufficient number of LED screens are placed in the vacuum hot-pressing mechanism 2, the mechanism is operated to perform vacuum hot-pressing on the surface of each LED screen, thereby removing air bubbles from the protective film. After vacuum hot-pressing and degassing, the film-applying process is complete. Finally, the film-applied LED screens are transported one by one to the film-removing mechanism 3, which peels off the protective film on the upper surface of the LED protective film. Through the coordinated action of the film-applying mechanism 1, the vacuum hot-pressing mechanism 2, and the film-removing mechanism 3, the LED screens undergo sequential film-applying, vacuum hot-pressing degassing, and film-removing processes. These processes are fully automated, requiring no operator intervention, greatly improving the production efficiency of LED screens.

[0031] like Figure 2-3As shown, the film application mechanism 1 includes a first support platform 11, which is equipped with a storage component 12 for storing stacked LED protective films. Multiple LED protective films are stacked together and stored on the storage component 12. The first support platform 11 is also equipped with a first support frame 13, which is equipped with a horizontally arranged first linear drive module 14. A vertically arranged second linear drive module 15 is mounted on the movable end of the first linear drive module 14. After the first linear drive module 14 is operated, its movable end (actuating end) moves horizontally to drive the second linear drive module 15 to move horizontally along a straight line. A lifting seat 16 is mounted on the movable end of the second linear drive module 15, and the lifting seat 16 is equipped with a picking component 17 for picking up individual LED protective films. After running the first linear drive module 14, the picking component 17 can be controlled to move laterally. After running the second linear drive module 15, the picking component 17 can be controlled to move up and down. The storage component 12 is placed at the beginning of the lateral movement trajectory of the picking component 17. When the picking component 17 moves laterally to directly above the storage component 12, the picking component 17 is controlled to move downward until it contacts the LED protective film stored on the storage component 12 and placed at the top. Then the picking component 17 is run to pick up the LED protective film. The picking component 17 is then controlled to move upward and laterally to transport the individual LED protective film to the subsequent film application station for film application, thus realizing the supply of LED protective film.

[0032] The first support platform 11 is equipped with a correction component 18, which is located next to the storage component 12 and is used to correct the position of the LED protective film picked up by the picking component 17. The correction component 18 is directly below the lateral movement trajectory of the picking component 17. Before transporting a single LED protective film to the subsequent film application station, the picking component 17 first transports it to the correction component 18. By operating the correction component 18, the position of the LED protective film is corrected to improve the accuracy of subsequent film application.

[0033] In order to supply materials to the LED screen and transport individual LED screens to the film application station for film application, the film application mechanism 1 also includes a first transport component 113 mounted on the first support platform 11 for continuously transporting the LED screen. The first support platform 13 is equipped with a third linear drive module 110 whose length direction is parallel to the length direction of the first linear drive module 14. The movable end of the third linear drive module 110 is equipped with a movable frame 111 that can move up and down. The movable frame 111 is equipped with a handling fixture 112 for clamping the LED screen. The end of the first transport component 113 connects to the beginning of the lateral movement trajectory of the handling fixture 112. After the first transport component 113 is in operation, it can continuously transport multiple LED screens. After a single LED screen is transported to the end of the first transport component 113, the movable frame 111 is first controlled to move downwards until the two clamping ends of the handling fixture 112 are respectively placed on both sides of the LED screen. Then, the handling fixture 112 is operated to clamp the LED screen. Subsequently, the movable frame 111 is controlled to move upwards, and then the third linear drive module 110 is operated to control the lateral movement of the handling fixture 112 and the LED screen it clamps, moving from the beginning to the end of the third linear drive module 110, thus realizing the transport of a single LED screen. The up and down movement of the movable frame 111 can be controlled by a cylinder.

[0034] In addition, a fourth linear drive module 114 is installed on the first support platform 11, which is arranged laterally and whose length direction is perpendicular to the length direction of the third linear drive module 110. A material transport platform 115 for transporting LED screens is installed on the movable end of the fourth linear drive module 114. The beginning of the moving trajectory of the material transport platform 115 is connected to the end of the lateral moving trajectory of the transport fixture 112, and the end of the moving trajectory of the material transport platform 115 is connected to the end of the lateral moving trajectory of the picking component 17.

[0035] When the material conveying platform 115 is in its initial position, it is at the beginning of its movement trajectory and at the end of the movement trajectory of the transport fixture 112. By controlling the vertical and horizontal movement of the transport fixture 112, the LED screen transported to the end of the first transport component 113 can be transported to the material conveying platform 115. Then, the fourth linear drive module 114 is run to control the horizontal movement of the material conveying platform 115 carrying the LED screen, from the end of the movement trajectory of the transport fixture 112 to the end of the movement trajectory of the picking component 17. At this time, the LED screen on the material conveying platform 115 is placed at the film application station, waiting for subsequent film application processing.

[0036] The LED protective film has a protective film attached to both its top and bottom surfaces. Before applying the LED protective film to the LED screen, the protective film on the bottom surface of the LED protective film must be removed first. To remove the protective film from the bottom surface of the LED protective film, a first film-removing component 117 is installed between the end of the movement trajectory of the correction component 18 and the conveying table 115. A first easy-tear adhesive feeding component 116 is also installed to provide easy-tear adhesive to the first film-removing component 117. A collection frame 118 for collecting the protective film is located directly below the first film-removing component 117. After the LED protective film is positioned and corrected by the material handling component 17 on the LED protective film transport and correction component 18, the corrected LED protective film is transported to a position directly above the first film-peeling component 117. The first film-peeling component 117 then takes a piece of easy-tear sticker from the first easy-tear sticker feeding component 116 and sticks it to the edge of the protective film on the lower surface of the LED protective film. The first film-peeling component 117 then pulls the easy-tear sticker and rotates it at a certain angle. Under the adhesive action of the easy-tear sticker, the protective film on the lower surface of the LED protective film is peeled off. The peeled-off protective film is then dropped into the collection box 118 for waste collection. Finally, the LED protective film is transported horizontally to a position directly above the LED screen (which is located at the film application station), and then the LED protective film is controlled to move downwards to apply it to the LED screen. This achieves automatic film application, with fully automated operation and no operator intervention required, thus improving the efficiency of LED screen film application.

[0037] The first easy-tear sticker feeding component 116 and the first film-removing component 117 mentioned above are both existing structures. For details of their structures, please refer to a screen film-removing machine with patent number CN201910704133.X. An existing screen film-removing machine discloses an easy-tear sticker mechanism for providing easy-tear stickers and a film-removing head mechanism for grabbing easy-tear stickers from the easy-tear sticker mechanism and performing film-removing operations on the screen. The specific structures of the first easy-tear sticker feeding component 116 and the first film-removing component 117 in this application are the same, and their functions and operating methods are the same. Therefore, they will not be described in detail here.

[0038] like Figure 4As shown, the first transport component 113 includes a fixed frame 1131 and an adjusting frame 1132 arranged side by side. The fixed frame 1131 is fixedly mounted on the first support platform 11. The first support platform 11 is equipped with a first slide rail 1133 arranged laterally. The adjusting frame 1132 can be slidably disposed on the first slide rail 1133 in a direction closer to or farther from the fixed frame 1131. The length direction of the first slide rail 1133 is perpendicular to the length direction of the third linear drive module 110. A belt conveyor module 1136 for supporting and transporting the LED screen is installed on the side where the fixed frame 1131 and the adjusting frame 1132 are close to each other. The belt conveyor module 1136 on the fixed frame 1131 cooperates with the belt conveyor module 1136 on the adjusting frame 1132 to support the LED screen. When both belt conveyor modules 1136 operate simultaneously, the LED screen can be conveyed. Furthermore, by controlling the adjusting frame 1132 to slide closer to or further away from the fixed frame 1131, the distance between the fixed frame 1131 and the adjusting frame 1132 can be adjusted, enabling the conveying of LED screens of different sizes. The belt conveyor module 1136 is an existing structure, consisting of a conveyor belt and several pulleys, which are driven by a motor and will not be described in detail here.

[0039] To adjust the distance between the fixed frame 1131 and the adjusting frame 1132, the first transport assembly 113 further includes a fixed seat 1134 mounted on the first support platform 11. A second lead screw 1135, whose length direction is parallel to the length direction of the first slide rail 1133, is rotatably mounted on the fixed seat 1134. The second lead screw 1135 is threadedly connected to the adjusting frame 1132. By rotating the second lead screw 1135, the adjusting frame 1132 can be driven to slide on the first slide rail 1133 in a direction closer to or further away from the fixed frame 1131.

[0040] In addition, a blocking cylinder 1137 with its telescopic rod facing upwards and positioned beside the end of the belt conveyor module 1136 is installed on the first support platform 11. A blocking component 1138 is installed on the end of the telescopic rod of the blocking cylinder 1137 to block the LED screen conveyed by the belt conveyor module 1136 to a designated transport position. After the belt conveyor module 1136 conveys the LED screen to its end, it is blocked by the blocking component 1138. At this time, the LED screen is positioned at the designated transport position, allowing the transport fixture 112 to accurately grasp and transport it. The blocking component 1138 also prevents the LED screen from deviating from its transport position due to its own inertia after the belt conveyor module 1136 stops abruptly, thus improving the accuracy of subsequent transport.

[0041] like Figure 5As shown, the storage component 12 includes a fixed plate 121 mounted on the first support platform 11. The fixed plate 121 is equipped with a lifting frame 123 that can move up and down. The top of the lifting frame 123 is equipped with a carrier plate 122 for carrying stacked LED protective films. The lifting frame 123 can be controlled to move up and down on the fixed plate 121 by the cooperation of a motor and a threaded rod, or by the drive of a cylinder. Multiple LED protective films are stacked together and stored on the carrier plate 122. After the picking component 17 removes the top LED protective film, it controls the lifting frame 123 to move upward to a specified height (the height is consistent with the thickness of an LED protective film). Each time an LED protective film is removed, the lifting frame 123 moves upward to the specified height. Under the intermittent upward movement of the lifting frame 123, the top LED protective film in the stack is always at the specified height so that the picking component 17 can pick it up.

[0042] The top surface of the fixed plate 121 is provided with a left limiting rail 126 and a right limiting rail 127 arranged horizontally. Both the left limiting rail 126 and the right limiting rail 127 extend upward to pass through the material carrier plate 122. The top surface of the fixed plate 121 is provided with a front limiting rail 124 and a rear limiting rail 125 arranged front to back. The rear limiting rail 125 can be slid laterally on the fixed plate 121 in the direction of approaching or moving away from the front limiting rail 124, and the sliding direction of the rear limiting rail 125 is perpendicular to the sliding direction of the left limiting rail 126 (or the right limiting rail 127). The left limit bar 126 and the right limit bar 127 are used to limit the left and right sides of the stacked LED protective film, and the front limit bar 124 and the rear limit bar 125 are used to limit the front and rear sides of the stacked LED protective film. With the communication between the two pairs of limit bars, the stacked LED protective film is prevented from collapsing when the carrier plate 122 moves intermittently upward. In addition, the left limit bar 126 and the right limit bar 127 can move laterally to adjust the distance between them. Similarly, the rear limit bar 125 can move laterally to adjust the distance between the rear limit bar 125 and the front limit bar 124, thereby adapting to LED protective films of different lengths or widths and improving the adaptability of the storage component 12.

[0043] A first lead screw 128 is rotatably mounted on the fixed plate 121, with its axis arranged laterally and aligned with the sliding direction of the rear limit bar 125. The first lead screw 128 is threadedly connected to the rear limit bar 125. By turning the first lead screw 128, the rear limit bar 125 can be controlled to slide laterally toward or away from the front limit bar 124.

[0044] A forward and reverse threaded screw 129 is rotatably mounted on a fixed plate 121, with its axis arranged laterally and perpendicular to the axis of the first threaded screw 128. Different threaded portions on the forward and reverse threaded screw 129 are threadedly connected to the left limit bar 126 and the right limit bar 127, respectively. By turning the forward and reverse threaded screw 129, the left limit bar 126 and the right limit bar 127 can be controlled to move closer to or further away from each other under the action of the different threaded portions.

[0045] like Figure 6-7 As shown, the material handling assembly 17 includes a connecting seat 171 mounted on the lifting base 16. The connecting seat 171 is equipped with a vacuum suction plate 172 for adhering to the LED protective film. The bottom surface of the vacuum suction plate 172 is provided with multiple second vacuum nozzles 178 for evacuating the vacuum. The multiple second vacuum nozzles 178 are connected to a vacuum evacuation device. After the vacuum suction plate 172 descends and contacts the uppermost LED protective film, the air is sucked away through the second vacuum nozzles 178, thereby allowing the vacuum suction plate 172 to pick up the LED protective film for transport. The principle of vacuum adsorption is existing technology and will not be described in detail here.

[0046] In addition, during the process of vacuum suction plate 172 sucking up LED protective film, the pressure difference formed between the gap between the upper and lower LED protective films and the outside atmosphere will cause the lower LED protective film to be lifted by the upper LED protective film. To solve this problem, the top surface of vacuum suction plate 172 is equipped with a lifting cylinder 173 with the telescopic rod facing upward. The end of the telescopic rod of lifting cylinder 173 is equipped with a first lifting frame 174. The first lifting frame 174 is equipped with multiple shaking modules for sucking up a single LED protective film and shaking it. Before the vacuum suction plate 172 picks up the LED protective film, it first uses multiple shaking modules to hold the topmost LED protective film (at this time, the vacuum suction plate 172 is not in contact with the LED protective film). After holding it, the vacuum suction plate 172 is controlled to move upward, and then multiple shaking modules are operated simultaneously to shake the held LED protective film up and down, shaking down the LED protective film that was lifted by the pressure difference, so as to achieve the picking up of a single LED protective film. After the shaking is completed, the lifting cylinder 173 is operated to control the first lifting frame 174 to move upward. The shaking module moves upward with the single LED protective film. After it moves to contact the bottom surface of the vacuum suction plate 172, the second vacuum nozzle 178 sucks away the air to pick up the single LED protective film, and then it is transported. By setting up multiple shaking modules, the material picking efficiency is improved.

[0047] The shaking module includes a shaking cylinder 175 mounted on the first lifting frame 174 with its telescopic rod facing downwards. The telescopic rod end of the shaking cylinder 175 has a mounting block 176, on which a first vacuum nozzle 177 for holding the LED protective film is mounted. The suction end of the first vacuum nozzle 177 extends downwards through the vacuum suction plate 172. Initially, the suction end of the first vacuum nozzle 177 is positioned below the vacuum suction plate 172, so that after the suction end of the first vacuum nozzle 177 contacts the LED protective film, the vacuum suction plate 172 will not contact the LED protective film. When shaking is required, the shaking cylinder 175 is activated, causing the telescopic rod to move up and down reciprocally, thereby causing the LED protective film to shake up and down via the first vacuum nozzle 177.

[0048] Additionally, a blower module 19 (such as a blower module 19) can be mounted on the first support platform 11 next to the storage component 12. Figure 5 As shown, during the process of picking up the LED protective film, the material picking component 17 operates the blowing module 19 to intervene by blowing air from the side onto the picked-up LED protective film. By forcibly injecting air into the low-pressure gap, the pressure difference between the inside and outside is quickly balanced. After the pressure difference is eliminated, the lower layer of LED protective film naturally falls off onto the storage component 12 under its own gravity. The material picking efficiency is further improved by setting up the blowing module 19.

[0049] like Figure 8-9 As shown, the correction assembly 18 includes a fixed platform 181 fixedly mounted on the first support platform 11. A feeding platform 182 for supporting a single LED protective film is mounted above the fixed platform 181. A left sliding seat 183 and a right sliding seat 184 are arranged horizontally on the bottom surface of the feeding platform 182. A left push block 185 is fixedly mounted on the left sliding seat 183, and a right push block 186 is fixedly mounted on the right sliding seat 184. Both the left push block 185 and the right push block 186 extend upwards to pass through the feeding platform 182. A fixed block 187 and a movable block 188 are arranged front to back on the top surface of the feeding platform 182. The movable block 188 can move towards or away from the fixed block 187 on the top surface of the feeding platform 182, and the direction of movement of the movable block 188 is perpendicular to the direction of movement of the left push block 185 (or the right push block 186).

[0050] After a single LED protective film is transported onto the feeding platform 182, it is positioned between the left push block 185 and the right push block 186, and between the fixed block 187 and the movable block 188. The feeding platform 182 has recessed grooves for the left push block 185 and the right push block 186 to move. First, the left sliding seat 183 and the right sliding seat 184 are moved closer to each other. The left push block 185 and the right push block 186 push the LED protective film along the X-axis to position its left and right sides. Then, the movable block 188 is moved closer to the fixed block 187 to push the LED protective film along the Y-axis to position its front and back sides. Through this arrangement, the LED protective film can be positioned at a designated location, and its position can be corrected.

[0051] In order to control the left sliding block 183 and the right sliding block 184 to move laterally toward each other or away from each other, the left sliding block 183 is equipped with a left connecting block 189, and the right sliding block 184 is equipped with a right connecting block 1810. The fixed platform 181 is equipped with a control module for controlling the left connecting block 189 and the right connecting block 1810 to move closer or further apart from each other.

[0052] The control module includes a left drive wheel 1811 and a right drive wheel 1812, rotatably mounted on a fixed platform 181 and arranged horizontally. A drive belt 1813 is wound around the left drive wheel 1811 and the right drive wheel 1812. The two halves of the drive belt 1813 are arranged front to back. The front half of the drive belt 1813 is fixedly connected to the right connecting block 1810, and the rear half of the drive belt 1813 is fixedly connected to the left connecting block 189. The two halves of the drive belt 1813 can also be arranged vertically. By driving the left drive wheel 1811 or the right drive wheel 1812 to rotate, the drive belt 1813 drives the left connecting block 189 and the right connecting block 1810 to move laterally towards or away from each other. This causes the left push block 185 and the right push block 186 to move closer or further away from each other, thus performing positioning and correction processing on the individual LED protective film placed on the feeding platform 182. In addition, a structure as described in the calibration component 18 can be set on the material handling platform 115 to calibrate the LED screen carried on the material handling platform 115, also to improve the accuracy of subsequent film application.

[0053] like Figure 10As shown, the vacuum hot pressing mechanism 2 includes a second support platform 21 and multiple vacuum hot pressing modules 22 mounted on the second support platform 21. A single vacuum hot pressing module 22 can simultaneously perform vacuum hot pressing on multiple LED screens with LED protective films. By setting multiple vacuum hot pressing modules 22, the efficiency of vacuum hot pressing on LED screens with LED protective films is improved. Vacuum treatment is used to eliminate air bubbles in the LED protective film, and hot pressing is used to heat the LED protective film. After heating the LED protective film to a specified temperature, it is pressed to completely cover the surface of the LED screen, avoiding the situation where air bubbles reappear after complete debubbling. The specific methods of vacuum treatment and hot pressing are described in detail below.

[0054] To facilitate the transfer of the LED screen with the LED protective film applied to the vacuum hot-pressing module 22 for vacuum hot pressing, a support truss 23 arranged laterally along its length is installed on the second support platform 21. One end of the support truss 23 is connected to the film-applying mechanism 1 used to apply the LED protective film to the LED screen. The support truss 23 is equipped with a first transport component 24 for transporting the LED screen with the LED protective film applied to the vacuum hot-pressing module 22, and a second transport component 25 for removing the LED screen after vacuum hot pressing from the vacuum hot-pressing module 22. After the film-applying mechanism 1 applies the LED protective film to the LED screen, the first transport component 24 is activated to transport the LED screens on the transport table 115 into the vacuum hot-pressing module 22. Multiple LED screens with applied LED protective films are then transported into the same vacuum hot-pressing module 22, which is then activated to simultaneously perform vacuum hot-pressing on multiple LED screens. After vacuum hot-pressing is complete, the vacuum hot-pressing module 22 is opened, and the second transport component 25 is activated to remove the vacuum-pressed LED screens from the module 22 and transfer them to the film-removing mechanism 3. With the cooperation of these components, automatic feeding, vacuum hot-pressing, and automatic unloading are achieved, requiring no human intervention throughout the process, thus improving the efficiency and safety of the vacuum hot-pressing process.

[0055] like Figure 11-13As shown, the vacuum hot pressing module 22 includes a support frame 221 and an upper sealing frame 222 mounted on the support frame 221. It also includes a transverse sliding plate 223 that is laterally slidably disposed on the second support platform 21. The transverse sliding plate 223 has a lower sealing frame 224 located directly below the upper sealing frame 222 and capable of vertical movement. The opening of the upper sealing frame 222 faces downward, and the opening of the lower sealing frame 224 faces upward. When the lower sealing frame 224 is at its lowest point, the upper sealing frame 222 and the lower sealing frame 224 are separated. At this time, the transverse sliding plate 223 can slide laterally on the second support platform 21. When the lower sealing frame 224 is controlled to move upward to its highest point, the upper sealing frame 222 and the lower sealing frame 224 are closed, and a sealed chamber is formed inside the upper sealing frame 222 and the lower sealing frame 224 to facilitate subsequent vacuuming.

[0056] Secondly, multiple hot-pressing components are installed inside the upper sealing frame 222 for hot-pressing LED screens with LED protective films. Each hot-pressing component can only hot-press one LED screen with an LED protective film. Therefore, within the sealed chamber after the upper sealing frame 222 and the lower sealing frame 224 are closed, multiple LED screens with LED protective films can be hot-pressed simultaneously, thereby improving the hot-pressing efficiency of the vacuum hot-pressing mechanism 2. Furthermore, each hot-pressing component is individually controlled, and different pressing pressures can be adjusted according to the thickness of the LED screen.

[0057] To control the vertical movement of the lower sealing frame 224, the transverse plate 223 is equipped with a sliding frame 225 that can slide vertically. The lower sealing frame 224 is fixedly mounted on the top of the sliding frame 225. The transverse plate 223 is equipped with a first cylinder 226 with its telescopic rod facing upward, and the end of the telescopic rod of the first cylinder 226 is fixedly connected to the bottom of the lower sealing frame 224. By operating the first cylinder 226, its telescopic rod extends and retracts, thereby controlling the vertical movement of the lower sealing frame 224, separating or closing it from the upper sealing frame 222.

[0058] In order to control the transverse plate 223 to slide laterally on the second support platform 21, the second support platform 21 is equipped with a transversely arranged second slide rail 227. The length direction of the second slide rail 227 is perpendicular to the transverse transport trajectory of the first transport assembly 24. The bottom of the transverse plate 223 is slidably connected to the second slide rail 227. The second support platform 21 is equipped with a rodless cylinder 228 whose length direction is parallel to the length direction of the second slide rail 227. The movable end of the rodless cylinder 228 is fixedly connected to the bottom of the transverse plate 223. By operating the rodless cylinder 228, the transverse plate 223 is controlled to slide laterally on the second slide rail 227. The transverse plate 223 moves laterally with the lower sealing frame 224. One end of the lateral movement trajectory of the lower sealing frame 224 is placed directly below the upper sealing frame 222, and the other end of the lateral movement trajectory of the lower sealing frame 224 is placed directly below the first transport assembly 24 and the second transport assembly 25. After the lower sealing frame 224 moves laterally to be directly below the first transport assembly 24 and the second transport assembly 25, the first transport assembly 24 is operated to transport the LED screen to be vacuum hot-pressed on the conveying platform 115 into the lower sealing frame 224. Then, the lower sealing frame 224 is controlled to move laterally to transport it directly below the upper sealing frame 222. After the lower sealing frame 224 moves upward, the LED screen to be vacuum hot-pressed is placed in the sealing chamber. After the lower sealing frame 224 moves laterally again to directly below the first transport component 24 and the second transport component 25, the second transport component 25 is operated to transport the LED screen, which has been vacuum-heat-pressed, from inside the lower sealing frame 224 to the film-tearing mechanism 3.

[0059] In addition, to achieve vacuuming of the aforementioned sealed chamber, a vacuum tube 229 is installed along the edge of the lower sealing frame 224, and the vacuum tube 229 is connected to a vacuuming device (not shown in the figure). After the upper sealing frame 222 and the lower sealing frame 224 are closed to form a sealed chamber, the vacuuming device is operated, and the air in the sealed chamber is removed through the vacuum tube 229, so that the LED protective film on the surface of the LED screen is in a vacuum negative pressure state. Under negative pressure, the LED protective film will be compressed and deformed, thereby compressing out the air bubbles inside the LED protective film, eliminating residual air bubbles inside the LED protective film, achieving degassing treatment, and improving the quality of the LED screen after film application. In this embodiment, a sealing ring 2210 is provided on the top surface of the lower sealing frame 224. After the top surface of the lower sealing frame 224 contacts the bottom surface of the upper sealing frame 222, the sealing ring 2210 fills the gap between the two, preventing air leakage during vacuuming and improving the efficiency of vacuuming.

[0060] Furthermore, the hot pressing assembly includes a lower heating plate 2211 installed inside the lower sealing frame 224, and a support plate 2212 for supporting the LED screen with the LED protective film attached on the top surface of the lower heating plate 2211; it also includes a pressing plate 2213 that is slidably disposed inside the upper sealing frame 222 and is used to apply pressure to the LED protective film, and an upper heating plate 2214 is installed on the bottom surface of the pressing plate 2213. Both the upper heating plate 2214 and the lower heating plate 2211 are equipped with heating tubes 2216 for heating.

[0061] The heat emitted by the heating element 2216 is transferred to the upper heating plate 2214 and the lower heating plate 2211, keeping them in a state of continuous heating. While performing vacuum degassing on the LED protective film on the LED screen surface, the pressing plate 2213 moves downwards to press the LED protective film. During pressing, the upper heating plate 2214 contacts the LED protective film, heating it to 120 degrees Celsius or higher. The lower heating plate 2211 also emits heat, ensuring the LED protective film is heated evenly and softened. Once softened, the LED protective film becomes adhesive. The pressing plate 2213 applies pressure to the softened LED protective film and presses it for 60 minutes, pressing the film firmly onto the LED screen surface. Through these steps, vacuum and hot-pressing processes for the LED protective film are achieved. The entire process is automated, requiring no operator intervention, thus improving the efficiency and safety of vacuum hot pressing.

[0062] In addition, a soft pad 2215 is provided on the bottom surface of the upper heating plate 2214 (i.e. the side that contacts the LED protective film). The soft pad 2215 is a soft, high-temperature resistant pad. When the pressing plate 2213 applies a certain pressure to the LED protective film, it contacts the LED protective film through the soft pad 2215 to protect the LED protective film and prevent damage to the LED protective film during the hot pressing process.

[0063] To control the sliding of the pressing plate 2213 within the upper sealing frame 222, a mounting bracket 2217 is provided on the top outer side of the upper sealing frame 222. The mounting bracket 2217 is equipped with a second cylinder 2218 with its telescopic rod facing downwards. The end of the telescopic rod of the second cylinder 2218 passes through the upper sealing frame 222 and is fixedly connected to the pressing plate 2213. By operating the second cylinder 2218, its telescopic rod extends and retracts, thus controlling the sliding of the pressing plate 2213 within the upper sealing frame 222. A sealing structure is provided between the telescopic rod of the second cylinder 2218 and the upper sealing frame 222. This sealing structure is existing technology and is used to prevent outside air from entering the sealed chamber through the gap between the telescopic rod of the second cylinder 2218 and the upper sealing frame 222 during vacuuming.

[0064] The first conveying component 24 and the second conveying component 25 have the same structure and operate in the same way, such as Figure 14 As shown, the second transport assembly 25 includes a transverse sliding seat 251 slidably mounted on the supporting truss 23 and a lifting plate 252 slidably mounted on the transverse sliding seat 251. A long cylinder with a downward-facing telescopic rod is mounted on the transverse sliding seat 251, the end of which is fixedly connected to the lifting plate 252. Operating the long cylinder allows its telescopic rod to extend and retract, controlling the lifting plate 252 to slide up and down on the transverse sliding seat 251. The lifting plate 252 is equipped with a third cylinder 253 with a downward-facing telescopic rod. A second lifting frame 254 is mounted on the end of the telescopic rod of the third cylinder 253, and the second lifting frame 254 is equipped with a clamping module for gripping the LED screen. The second transport assembly 25 also includes a first control assembly for controlling the transverse sliding seat 251 to slide laterally on the supporting truss 23. The first control component controls the transverse sliding seat 251 to slide laterally on the support truss 23, thus enabling the clamping module to move laterally. The long cylinder and the third cylinder 253 control the clamping module to move up and down. After the clamping module clamps the LED screen on the support plate 2212, controlling its up-and-down and lateral movements allows for the transport of the LED screen, which has undergone vacuum hot pressing on the support plate 2212, to the film-peeling mechanism 3. The first transport component 24 then transports the LED screen from the conveying table 115 to the support plate 2212.

[0065] In this embodiment, the clamping module includes a left clamping block 255 and a right clamping block 256 symmetrically arranged and laterally slidable on the second lifting frame 254. The second lifting frame 254 is equipped with a gripper cylinder 257 positioned between the left clamping block 255 and the right clamping block 256. Both the left clamping block 255 and the right clamping block 256 are fixedly equipped with connecting rods 258. The two gripper ends of the gripper cylinder 257 are respectively fixedly connected to different connecting rods 258. By operating the gripper cylinder 257, its two gripper ends move closer or further apart. Under the driving action of the connecting rods 258, the left clamping block 255 and the right clamping block 256 are controlled to move closer or further apart, thereby clamping or releasing the LED screen.

[0066] Additionally, the first control component includes a pair of support blocks 259 respectively positioned at both ends of the lateral movement trajectory of the transverse sliding seat 251. Each support block 259 is rotatably equipped with a synchronous pulley 2510, and a synchronous belt 2511 is wound around the two synchronous pulleys 2510. The two halves of the synchronous belt 2511 are arranged vertically (or horizontally), with the upper half of the synchronous belt 2511 fixedly connected to the transverse sliding seat 251. The first control component also includes a servo motor 2512 mounted on the support truss 23, with the output shaft of the servo motor 2512 fixedly connected to one of the synchronous pulleys 2510. Running the servo motor 2512 drives the synchronous pulley 2510 to rotate, thereby moving the synchronous belt 2511 and controlling the transverse sliding seat 251 to slide laterally on the support truss 23. The transport fixture 112 has the same structure and operating mode as the fixture module.

[0067] like Figure 15 As shown, the film-tearing mechanism 3 includes a third support platform 31 and a third slide rail 32 horizontally disposed on the top surface of the third support platform 31. A slide plate is horizontally slidably disposed on the third slide rail 32. A second transport component 33 is mounted on the slide plate for supporting and transporting the LED screen that has undergone vacuum hot pressing. A side fixing component 34 for fixing the LED screen is mounted on the side of the second transport component 33. The second transport component 33 has the same structure and operation as the first transport component 113. When the slide plate is placed at the beginning of the third slide rail 32, the second transport component 25 can transport the LED screen that has undergone vacuum hot pressing onto the second transport component 33, support it through the second transport component 33, and then operate the side fixing component 34 to fix the LED screen on the second transport component 33, so as to prevent the position from shifting during the subsequent film-tearing process. The side fixing assembly 34 includes an electric push rod and a pressure block fixed to the end of the telescopic rod of the electric push rod. The electric push rod is arranged laterally. After the LED screen is transported to the second transport assembly 33, the electric push rod is operated, and its telescopic rod extends to push the pressure block to move laterally until it contacts the side of the LED screen. The pressure block presses the LED screen tightly, thereby fixing the LED screen.

[0068] To control the lateral sliding of the skateboard on the third slide rail 32, the third support platform 31 is equipped with a second control component 35 for controlling the lateral movement of the skateboard. The second control component 35 has the same structure and operates in the same way as the first control component. By operating the second control component 35, the skateboard can be controlled to move from the beginning to the end of the third slide rail 32, and during the lateral movement, the LED screen is peeled off. After the film is peeled off, the electric push rod releases the LED screen, and then the second transport component 33 is operated to transport the peeled LED screen to the next device.

[0069] In order to remove the protective film on the upper surface of the LED protective film (the LED protective film attached to the surface of the LED screen) after vacuum hot pressing degassing, a second support frame 37 and a second easy-tear adhesive feeding assembly 36 for continuously providing easy-tear adhesive are installed on the third support platform 31. The second support frame 37 is provided with a fifth linear drive module 38 arranged laterally and whose length direction is perpendicular to the length direction of the third slide rail 32. A sixth linear drive module 39 is arranged vertically on the movable end of the fifth linear drive module 38. A second film-removing assembly 310 for removing the protective film on the upper surface of the LED protective film is installed on the movable end of the sixth linear drive module 39.

[0070] The second easy-tear adhesive feeding assembly 36 has the same structure and operates in the same manner as the first easy-tear adhesive feeding assembly 116. The second film-removing assembly 310 has the same structure and operates in the same manner as the first film-removing assembly 117. When the second transport component 33 carrying the LED screen moves laterally to below the sixth linear drive module 39, the fifth linear drive module 38 is first activated to control the sixth linear drive module 39 and the second film-peeling component 310 to move laterally. When it moves to the position of the second easy-tear sticker feeding component 36, an easy-tear sticker can be picked up. Then, the sixth linear drive module 39 and the second film-peeling component 310 are controlled to return to their original position laterally. After returning to their original position, the sixth linear drive module 39 is activated to control the second film-peeling component 310 to move downward, sticking the removed easy-tear sticker to the edge of the protective film on the upper surface of the LED protective film. The second film-peeling component 310 is activated to pull the easy-tear sticker and rotate it at a certain angle. At the same time, the second transport component 33 moves laterally with the LED screen. The fifth linear drive module 38 again controls the sixth linear drive module 39 and the second film-peeling component 310 to move laterally. Under the adhesive action of the easy-tear sticker, the protective film on the upper surface of the LED protective film is peeled off, completing the film-peeling process.

[0071] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0072] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
