The mounting frame is mounted on the drive end of the lead screw drive frame. The two lead screws are coaxially and rotatably mounted on the mounting frame, and the threads of the two lead screws are arranged in opposite directions. The two clamping frames are symmetrically and slidably mounted on the mounting frame and are respectively threadedly driven connected to the two lead screws. The two extension... The lead screw is rotatably mounted on two clamping frames, and the two clamping blocks are fixedly mounted on the two clamping frames, with the clamping blocks located in the middle of the clamping frames. The clamping frames are provided with multiple movable clamping blocks on both sides of the clamping blocks. The multiple movable clamping blocks are threadedly driven by the extension lead screw, and the threads on both sides of the extension lead screw are opposite with the clamping blocks as the center point. Multiple photographic detection elements are provided below the lead screw drive frame. The multiple photographic detection elements are arranged at equal intervals along the width of the lead screw drive frame, and there is a detection gap between adjacent photographic detection elements to accommodate the thickness of the clamping blocks.

[0014] Both the clamping block and the moving clamping block are equipped with miniature electric push rod actuators. The driving end of the miniature electric push rod actuator is set towards the clamping block on the other side, and a clamping rubber block is installed on the driving end of the miniature electric push rod actuator.

[0015] An anti-reflective display screen is characterized by comprising a glass substrate, a flame-retardant adhesive film, an anti-reflective film, a protective film, and a scratch-resistant film, wherein the glass substrate, the flame-retardant adhesive film, the anti-reflective film, the protective film, and the scratch-resistant film are stacked and connected in sequence to form a core display layer, and polarizers are adhered to the upper and lower sides of the core display layer.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention provides a high-efficiency double-sided display screen laminating device. During production, the substrate is placed on the input conveyor belt, and then the substrate is clamped on the placement tray by the first transfer gripper. The placement tray is then rotated to place the substrate under different film stacking holders for film stacking. The films are stacked sequentially under the second transfer gripper, and the second transfer gripper places the laminated substrate on the output conveyor belt for output lamination. This reduces space occupation and also enables multi-layer film stacking.

[0018] 2. The present invention provides a high-efficiency double-sided display screen bonding device. During bonding, the substrate is placed on the fixture by a transfer clamp, and then the cylinder drives the fixture to be positioned below the bonding machine for bonding. After the first bonding is completed, the fixture is reset, and then the rotating mechanism on the fixture drives the fixing plate to flip towards another fixture, so that the substrate on the fixing plate is flipped and placed on the other fixture, thereby bonding the other side, realizing automatic double-sided bonding.

[0019] 3. The present invention provides a high-efficiency double-sided display screen laminating device, wherein a rodless push cylinder drives a sliding seat to be placed along a guide rail at the input end of a stacking conveyor belt. Then, one side of the display screen is placed on a support rod, and the other side is placed on the stacking conveyor belt, so that the display screen is tilted. Then, one side of the next display screen is placed on the same side of the display screen on the stacking conveyor belt, and the other side is also placed on the stacking conveyor belt, and so on, stacking them sequentially. While the stacking conveyor belt is transporting, the rodless push cylinder drives the sliding seat to move along the guide rail and follow the stacking conveyor belt, thereby ensuring that one side of the first display screen is tilted up to facilitate the stacking gripping component to grip it.

[0020] 4. This invention provides a high-efficiency double-sided screen laminating device. During the stacking gripping assembly, one clamping end of the stacking gripping assembly abuts against the underside of the first screen's raised side, and a support rod abuts against the bottom of the screen. The conveyor belt then continuously transports the screens. When the screens encounter an obstruction, they stand upright and stack together. When a specified number of screens are stacked, the other clamping end of the stacking gripping assembly clamps them, thus lifting the stacked screens. Even when higher than the support rod, one side of the grabbed screen remains on top of the grabbed screen. A rodless cylinder drives a sliding seat to move along the guide rail and position it under the ungrabbed screen, supporting it and ensuring that one side of the screen is raised for easy gripping by the stacking gripping assembly.

[0021] 5. This invention provides a high-efficiency double-sided screen laminating device. Stacked screens are placed between two clamping frames. Two drive screws drive the two clamping frames to move towards each other, thereby clamping and fixing multiple screens one by one through clamping blocks and multiple movable clamping blocks. Then, by rotating the extension screw, the multiple movable clamping blocks move to create a distance, resulting in a detection gap between adjacent screens. A screw drive frame then drives a mounting frame to move, placing the screens above multiple photographic inspection pieces. A lift then drives the screw drive frame to lower the mounting frame, placing the screens between adjacent photographic inspection pieces for inspection. After inspection, the lift rises. If there are no problems, the extension screw drives the multiple movable clamping blocks to reset the screens and re-stack them in the intact product storage box. If there are problems, the clamping block holding the problematic clamping block or the miniature electric push rod actuator on the movable clamping block drives the clamping rubber block away from the screen, releasing the screen and causing it to fall into the defective product storage box. The remaining extension screw drives the multiple movable clamping blocks to reset the screens and re-stack them in the intact product storage box, achieving automatic simultaneous inspection of multiple screens.

[0022] 6. Anti-reflective display screen: The anti-reflective film increases the screen's anti-reflective ability, and protective and scratch-resistant films are added for added protection. Attached Figure Description

[0044] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0045] like Figures 1-17As shown, this embodiment provides a high-efficiency double-sided display screen laminating equipment, including a laminating device 1, a patching device 2, and a testing and stacking device 3. The laminating device 1, patching device 2, and testing and stacking device 3 are arranged and connected in sequence. The laminating device 1 includes a rotating frame 101, an input conveyor belt 102, an output conveyor belt 103, and multiple laminating clamps 104. A placement tray 105 is rotatably mounted on the rotating frame 101. The input conveyor belt 102 and the output conveyor belt 103 are symmetrically mounted on the rotating frame 101 and located on both sides of the placement tray 105. A first transfer gripper 106 and a second transfer gripper 107 are respectively provided on one side of the input conveyor belt 102 and the output conveyor belt 103. The output conveyor belt 103 is located between the rotating frame 101 and the patching device 2. Multiple laminating clamps 104 are rotatably mounted on the rotating frame 101 around the placement tray 105. A film conveyor 108 is installed on one side of the laminating clamp 104. Specifically, the rotating frame 101 has a dust cleaner 109 on the side of the first transfer gripper 106 away from the input conveyor belt 102. This dust cleaner cleans the substrate before lamination to prevent particle generation. During production, the substrate is placed on the input conveyor belt 102, then clamped onto the placement tray 105 by the first transfer gripper 106. The placement tray 105 is then rotated to place the substrate under different lamination holders 104 for lamination. The laminated substrates are then sequentially placed under the second transfer gripper 107, and finally placed on the output conveyor belt 103 for output bonding via the second transfer gripper 107. This process reduces space requirements and enables multi-layer film stacking.

[0046] Furthermore, a plurality of positioning plates 1010 are equidistantly arranged on the placement tray 105. A plurality of threaded holes 1011 are evenly arranged on each positioning plate 1010. Adjusting bolts 1012 are threaded onto each threaded hole 1011, and limiting plates 1013 are slidably mounted on the adjusting bolts 1012. The position of the limiting plate 1013 can be adjusted according to the size of the substrate using the adjusting bolts 1012, thereby adapting to the size of the substrate.

[0047] Furthermore, the placement equipment 2 includes a worktable 201, two transfer grippers 202, two retainers 203, and two placement devices 204. The worktable 201 is positioned downstream of the lamination equipment 1. The two transfer grippers 202 are symmetrically mounted on the worktable 201. The two retainers 203 are located between the two transfer grippers 202. The two placement devices 204 are mounted on the worktable 201. The worktable 201 is provided with drive cylinders 205 that drive the two retainers 203 to move back and forth between the transfer grippers 202 and the placement devices 204. Specifically, the fixture 203 includes a movable seat 206, a rotating mechanism 207, and a fixed plate 208. The movable seat 206 is mounted on the driving end of the driving cylinder 205, the rotating mechanism 207 is mounted on the movable seat 206, one side of the fixed plate 208 is mounted on the rotating end of the rotating mechanism 207, an adsorption head is provided below the fixed plate 208, and an adsorption port 209 communicating with both ends of the adsorption head is provided on the fixed plate 208. During the placement process, the substrate is placed on the fixture 203 by the transfer clamp 202, and then the drive cylinder 205 drives the fixture 203 to be positioned below the placer 204 for placement. After the first placement is completed, the fixture 203 is reset, and then the rotating mechanism 207 on the fixture 203 drives the fixture plate 208 to flip toward another fixture 203, so that the substrate on the fixture plate 208 is flipped and placed on the other fixture 203, thereby performing placement on the other side, realizing automatic double-sided placement. After the placement is completed, it is transferred to the inspection and stacking device 3 by another transfer clamp 202 for inspection and stacking.

[0048] Furthermore, the transfer clamp 202 includes a horizontal rodless cylinder 2010 and a lifting vacuum adsorption component 2011. The horizontal rodless cylinder 2010 is fixedly mounted on the worktable 201, and the lifting vacuum adsorption component 2011 is mounted on the moving end of the horizontal rodless cylinder 2010. The horizontal rodless cylinder 2010 drives the lifting vacuum adsorption component 2011 to move along the output direction of the output conveyor belt 103. By driving the lifting vacuum adsorption component 2011 to move, the lifting vacuum adsorption component 2011 transfers data to the display screen through lifting and clamping.

[0049] Furthermore, the stacking inspection device 3 includes a stacking conveyor belt 301, a stacking gripper assembly 302, and a detection assembly 303. The stacking conveyor belt 301, the stacking gripper assembly 302, and the detection assembly 303 are connected in sequence. The stacking conveyor belt 301 is installed at the output of the patch device 2. A rodless push cylinder 304 and a guide rail 305 are respectively installed on the symmetrical sides of the stacking conveyor belt 301. A sliding seat 306 is provided on the rodless push cylinder 304. One side of the sliding seat 306 extends onto the guide rail 305 and is slidably connected to the guide rail 305. A support rod 307 is provided on the sliding seat 306. The support rod 307 is horizontally arranged with the transmission plane of the stacking conveyor belt 301. The rodless push cylinder 304 drives the sliding seat 306 to be placed along the guide rail 305 at the input end of the stacking conveyor belt 301. Then, one side of the display screen is placed on the support rod 307 and the other side is placed on the stacking conveyor belt 301, so that the display screen is tilted. Then, one side of the next display screen is placed on the same side of the display screen on the stacking conveyor belt 301, and the other side is also placed on the stacking conveyor belt 301, and so on. While the stacking conveyor belt 301 is transporting, the rodless push cylinder 304 drives the sliding seat 306 to move along the guide rail 305 to follow the stacking conveyor belt 301, so as to ensure that one side of the first display screen is tilted up to facilitate the stacking gripping component 302 to grip it.

[0050] Furthermore, when the stacking gripping component 302 clamps, one clamping end of the stacking gripping component 302 abuts against the underside of the first display screen and, in conjunction with the support rod 307, abuts against the underside of the display screen. Then, the stacking conveyor belt 301 continuously transports the display screens. When the display screens are obstructed, they stand up and stack together. When a specified number are stacked, the other clamping end of the stacking gripping component 302 clamps the stacked display screens, thereby picking them up. When the stacked display screens are higher than the support rod 307, one side of the picked display screen is still placed on the picked display screen. Thus, the rodless push cylinder 304 drives the sliding seat 306 to move along the guide rail 305 and place it under the unpicked display screen to support it, thereby ensuring that one side of the display screen is raised to facilitate the stacking gripping component 302 to pick it up.

[0051] Furthermore, the stacking gripping assembly 302 includes a bracket 308, a lead screw drive 309, a drive frame 3010, a dual lifting cylinder 3011, a rotary motor 3012, and a clamping component 3013. The bracket 308 is installed downstream of the stacking conveyor belt 301, the lead screw drive 309 is installed on the bracket 308, the drive frame 3010 is connected to the lead screw drive 309, the dual lifting cylinder 3011 is installed on the drive frame 3010, and the rotary motor 3012 is installed on the lifting end of the dual lifting cylinder 3011. The clamping member 3013 is installed on the rotating end of the rotary motor 3012. The clamping member 3013 includes a mounting plate 3014, two swing motors 3015 and two horizontally moving clamping plates 3016. The mounting plate 3014 is installed on the rotating end of the rotary motor 3012. The two swing motors 3015 are symmetrically installed on both sides of the mounting plate 3014. The two horizontally moving clamping plates 3016 are symmetrically installed on the other two sides of the mounting plate 3014. The swing ends of the swing motors 3015 are equipped with clamping claws 3017. The drive frame 3010 is moved by the lead screw drive 309, and the rotary motor 3012 is started by the double lifting cylinder 3011 to move and lift the clamping component 3013. When gripping, the clamping claw 3017 on one side abuts against the top of the raised side of the first display screen, and then the swing motor 3015 drives the other clamping claw 3017 to lift up, so that the display screen can pass through. When a specified number is stacked, the clamping claw 3017 at the swing end of the swing motor 3015 clamps it, and the two horizontally moving clamping plates 3016 cooperate to clamp and arrange the display screen, so that it is placed in the detection component 303 for detection.

[0052] Furthermore, the detection component 303 includes a lead screw drive frame 3018, a mounting frame 3019, two drive lead screws 3020, two clamping frames 3021, two extension lead screws 3022, and two clamping blocks 3023. The lead screw drive frame 3018 is located downstream of the stacking gripping component 302, and a lifting platform 3024 for driving the lead screw drive frame 3018 to move up and down is provided below the lead screw drive frame 3018. The mounting frame 3019 is mounted on the drive end of the lead screw drive frame 3018. The two drive lead screws 3020 are coaxially rotatably mounted on the mounting frame 3019, and the threads of the two drive lead screws 3020 are arranged in opposite directions. The two clamping frames 3021 are symmetrically slidably mounted on the mounting frame 3019 and are respectively threadedly driven connected to the two drive lead screws 3020. The two extension lead screws 3022 are respectively rotatably mounted on the two clamping frames 3021, and the two clamping blocks 3023 are respectively fixedly mounted on the two clamping frames. On the clamping frame 3021, the clamping block 3023 is located in the middle of the clamping frame 3021. Multiple movable clamping blocks 3025 are movably mounted on both sides of the clamping block 3023 on the clamping frame 3021. These movable clamping blocks 3025 are threadedly driven by the extension screw 3022, and the extension screw 3022 has opposite threads on both sides with the clamping block 3023 as its center point. Multiple photographic detection elements 3026 are located below the screw drive frame 3018. The photodetectors 3026 are arranged at equal intervals along the width of the lead screw drive frame 3018, and there is a detection gap between adjacent photodetectors 3026 to accommodate the thickness of the clamping block 3023. Both the clamping block 3023 and the moving clamping block 3025 are equipped with miniature electric push rod actuators 3027. The drive end of the miniature electric push rod actuator 3027 faces the clamping block 3023 on the other side, and a clamping rubber block 3028 is installed on the drive end of the miniature electric push rod actuator 3027. Specifically, a backlight is provided on the side of the photodetector 3026 facing the other photodetector 3026. The backlight illuminates the display screen, allowing the photodetector 3026 to capture and detect any problems with the display screen.The stacked displays are placed between two clamping frames 3021. Two drive screws 3020 drive the two clamping frames 3021 to move towards each other, thereby clamping and fixing multiple displays one by one through clamping blocks 3023 and multiple movable clamping blocks 3025. Then, the extension screw 3022 rotates, causing the multiple movable clamping blocks 3025 to move and create a distance between adjacent displays, thus creating a detection gap. Then, the screw drive frame 3018 drives the mounting frame 3019 to move, positioning the displays above multiple photographic inspection pieces 3026. Finally, the lift 3024 drives the screw drive frame 3018 to lower the mounting frame 3019, placing the displays on the... The adjacent photographic inspection pieces 3026 are inspected. After the inspection is completed, the elevator 3024 is driven to rise. If there is no problem, the extension screw 3022 drives multiple moving clamps 3025 to reset the display screen and place it back into the intact product storage box. If there is a problem, the clamping block 3023 with the problem or the miniature electric push rod actuator 3027 on the moving clamp 3025 drives the clamping rubber block 3028 away from the display screen, thereby releasing the display screen and causing it to fall into the defective product storage box. The remaining extension screw 3022 drives multiple moving clamps 3025 to reset the display screen and place it back into the intact product storage box, realizing automatic simultaneous inspection of multiple items.

[0053] The anti-reflective display screen includes a glass substrate 4, a flame-retardant adhesive film 5, an anti-reflective film 6, a protective film 7, and a scratch-resistant film 8. The glass substrate 4, flame-retardant adhesive film 5, anti-reflective film 6, protective film 7, and scratch-resistant film 8 are stacked sequentially to form a core display layer. Polarizing films 9 are adhered to the top and bottom sides of the core display layer. The anti-reflective film 6 increases the screen's anti-reflective capability, and the protective film 7 and scratch-resistant film 8 provide added protection.
