Description

TECHNICAL FIELD

[0001] The application provides a touch display screen production device, and relates to the technical field of automatic assembly equipment for touch display screens, in particular to a full-automatic water adhesive bonding production device for touch display screens. BACKGROUND

[0002] A touch display screen is an interactive device integrating a touch function into a display device and has been widely used in various electronic products, and is composed of multiple layers of structures bonded together, and water adhesive bonding technology is a core process for manufacturing the touch display screen.

[0003] Existing automatic water adhesive bonding equipment is suitable for the production of large-size screens with a size of 32 inches to 110 inches, but the yield of the touch display screen with a size of more than 110 inches is only 85%, because no other supporting structure can be arranged on the point adhesive panel bonding surface, and when the panel is bonded by turning over, the panel will be deformed in an arc shape inwardly due to the influence of gravity, and the positioning of the deformed panel will cause bonding misalignment, thereby generating a large number of substandard products.

[0004] Therefore, the technical personnel in the field propose a full-automatic water adhesive bonding production device for touch display screens, which improves the positioning mechanism of the existing water adhesive bonding equipment, so that the positioning calibration can be automatically performed in the production of the touch display screen with a size of more than 110 inches, thereby reducing the substandard product rate. SUMMARY

[0005] In view of the defects of the prior art, the application provides a full-automatic water adhesive bonding production device for touch display screens, which is characterized in that a sealing dish for abutting against the panel is arranged on the inner side of a turning positioning frame for panel fixing and adhesive application, and when the panel is deformed due to gravity, the sealing dish in contact with the panel is correspondingly tilted at an angle, the tilt angle of the liquid surface is measured by an infrared measuring device, and the deformation amount of the panel is calculated, the Mark alignment point arranged on the inner side of the turning positioning frame is correspondingly moved according to the deformation amount of the panel, and the purpose of automatically changing the bonding point according to the change of the deformation amount of the panel is achieved, thereby improving the panel bonding precision.

[0006] To achieve the above object, the application is implemented by the following technical scheme: a full-automatic water adhesive bonding production device for touch display screens, comprising a turning positioning frame for panel fixing and adhesive application, the panel is placed on the turning positioning frame for fixing, and adhesive is applied on the surface of the panel, and then the panel is turned over and bonded by the turning positioning frame.

[0007] The inner side of the edge of the turning positioning frame is provided with a sealing dish, the sealing dish is filled with a liquid medium with good flowability, the sealing dish abuts against the panel, and as the panel is deformed and recessed inwardly under the action of gravity, the sealing dish is correspondingly tilted, and the deformation data of the panel is reflected by the included angle between the liquid in the sealing dish and the horizontal plane.

[0008] A float is provided inside the sealing dish, and the angle of the float changes accordingly as the liquid inside the sealing dish tilts.

[0009] An infrared measuring device is fixed to the outer side of the sealing dish corresponding to the float. The infrared measuring device emits infrared rays to the float and receives the reflected infrared rays at the float. By measuring the distance between the incident beam and the reflected beam, the tilt angle of the liquid medium in the sealing dish is calculated, thereby realizing the accurate measurement of the panel deformation.

[0010] The inner side of the flip positioning frame is provided with a Mark alignment point. The Mark alignment point is a key reference mark used for precise positioning in electronic manufacturing. It is a solid circular mark and provides a coordinate reference for the water-based adhesive bonding production of the touch screen through an optical recognition system, ensuring the precise alignment of the panel.

[0011] The Mark alignment point is fixedly connected to a traction harness. The PCL control system drives the traction harness to pull the Mark alignment point for adjustment and positioning based on the measurement data of the infrared measuring device. By calculating the deformation of the panel under the influence of gravity, the Mark alignment point of the panel is recalibrated. This enables the equipment to process smaller panels and, in the processing of larger panels, to intelligently adjust the position of the Mark alignment point through the PCL control system.

[0012] Preferably, a vertical rod is fixed at the midpoint of the side of the float, and the angle of the vertical rod, which is fixed to the float, changes synchronously with the horizontal displacement of the liquid in the sealed dish.

[0013] The inner wall of the sealing dish is fixed with a guide rod corresponding to the diameter of the upright. The upright is deflected at an angle along the direction of the guide rod. The infrared measuring device is installed along the direction of the guide rod corresponding to the upright, ensuring the installation angle between the infrared measuring device and the upright, thereby ensuring that the infrared measuring device receives the reflected light from the side of the upright.

[0014] Preferably, a reflector is fixed to the side of the pole corresponding to the infrared measuring device. The infrared measuring device is arranged parallel to the reflector. The infrared rays emitted by the infrared measuring device are received by the infrared measuring device after being reflected by the reflector. By measuring the distance between the infrared emitting point and the receiving point, and combining it with the installation distance between the pole and the infrared measuring device, the deflection angle of the pole is calculated.

[0015] A limiting ball is fixed at the end of the upright away from the float. The diameter of the limiting ball is larger than the spacing of the guide rod, so that the flip positioning frame is always within the limiting range of the guide rod when it is inverted or the upright is deflected. The sealed dish is filled with liquid medium to make the limiting ball float up to a certain height away from the guide rod. The deflection angle of the upright is within the accurate measurement range of the infrared measuring device.

[0016] Preferably, the float has a protrusion fixed on its side along the extension direction of the traction harness. The float is slidably mounted inside the sealing dish by the protrusion, which avoids the change in the installation angle of the float as the medium in the sealing dish flows, thus avoiding affecting the light reflection angle between the float and the infrared measuring device, ensuring the accuracy of the measurement data. Furthermore, as the panel deforms under the action of gravity, the protrusion will not affect the angle deflection of the float as it flows with the medium.

[0017] The traction harness is connected to a roller at its end. The PCL control system winds the traction harness around the roller and drives the Mark alignment point to move along the inner wall of the flip positioning frame. The PCL control system drives the rotation of the roller in a specific direction to wind up the traction harness, thereby realizing the movement and traction of the Mark alignment point fixed on the traction harness.

[0018] Preferably, the inner wall of the flip positioning frame is fixed with a guide rail along the diagonal direction. The Mark alignment point is slidably set inside the flip positioning frame through the guide rail. The deformation of the panel under gravity will be from the outside to the inside, and the displacement in the diagonal direction is the most obvious. Therefore, the guide rail is set along the diagonal direction to most accurately reflect the degree of deformation.

[0019] The roller bearing is located inside the guide rail. The two ends of the traction harness are driven by rollers. The Mark positioning point is adjusted by controlling the rollers at both ends of the traction harness.

[0020] Preferably, an installation slide rail is fixed to the inner wall of the edge of the flip positioning frame, and a slider is slidably engaged on the inner side of the installation slide rail. The sealing dish is slidably installed on the inner side of the flip positioning frame via the slider. The sealing dish slidably installed via the installation slide rail not only facilitates angle changes with the deformation of the panel, but also facilitates the leveling of the sealing dish.

[0021] Preferably, the side of the flip positioning frame is fitted with a sliding rail that passes through it and is threaded with a leveling bolt. The leveling bolts are pressed against the side wall of the slider and are symmetrically arranged. The leveling bolts are used to press against the slider to adjust the level of the sealing dish.

[0022] Preferably, a clamping block is slidably provided on the inner side of the mounting slide rail and on the side of the slider away from the leveling bolt. A spring is fixed between the slider and the clamping block. The clamping block serves as an intermediate medium for the leveling bolt to level the slider, which not only buffers the rigid adjustment of the leveling bolt, but also ensures that the sealing dish can deflect as the panel deforms.

[0023] This invention discloses a fully automated water-based adhesive bonding production equipment for touch screens, which has the following beneficial effects:

[0024] 1. This fully automatic water-based adhesive bonding production equipment for touch screens incorporates a sealing dish structure on the inner side of the existing flip positioning frame that presses against the panel. When the panel deforms under gravity, it causes the sealing dish in contact with it to deflect at an angle. The deformation of the panel is calculated by measuring the angle between the liquid plane inside the sealing dish and the horizontal plane. Then, the PLC system drives the Mark alignment point, which is slidably installed inside the flip positioning frame, to move in an orientation, changing the alignment point of the panel. The panel is then bonded according to the alignment point after deformation. The equipment automatically calibrates the mark position according to different panel sizes, enabling the processing and use of large-sized panels.

[0025] 2. This fully automatic water-based adhesive bonding production equipment for touch screens features a vertically fixed support rod on the side of the float. As the sealing dish deforms and changes angle with the panel, the support rod also changes angle with the tilt of the liquid surface. Since the tilt angle of the support rod is measured by reflected infrared light, it is necessary to ensure that the infrared measuring structure corresponds to the reflective sheet on the side of the support rod. A guide rod is fixed inside the sealing dish to the support rod, and a protrusion is fixed on the side of the float to guide the float, ensuring that the float always corresponds to the angle of the infrared measuring structure when the angle changes. In addition, to prevent the float from falling out of the range of the guide rod when the flip positioning frame is flipped, a limit ball structure is also fixed at the end of the support rod.

[0026] 3. This fully automatic water-based adhesive bonding production equipment for touch screens uses a rotating positioning frame to slide and install a sealing dish on the inside via a guide rail. Additionally, the slider used to fix the sealing dish has a spring-loaded clamping block on its side. The clamping block is then leveled using symmetrically arranged leveling bolts. This not only ensures that the sealing dish deflects at an angle as the panel deforms, but also allows for the calibration and adjustment of the sealing dish and the infrared measurement structure using the symmetrically arranged leveling bolts.

[0027] 4. This fully automatic water-based adhesive bonding production equipment for touch screens features a sliding rail installed along the diagonal direction inside the flip positioning frame. The Mark alignment point is slidably installed along the sliding rail. The PLC device calculates the measurement data from the infrared measuring structure and then controls the rotation of the roller accordingly. The roller is pulled by the traction harness to change the position of the Mark alignment point slid along the sliding rail. Furthermore, the position of the alignment point is adjusted according to the different degrees of deformation of panels of different sizes, ensuring the production accuracy of the equipment in bonding large-diameter panels.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention discloses a fully automated water-based adhesive bonding production equipment for touch screens;

[0038] According to the appendix Figures 1-6As shown, it includes a flip positioning frame 1 for fixing and applying adhesive to the panel. The panel is placed on the flip positioning frame 1 for fixing, adhesive is applied to its surface, and then the panel is flipped and pasted through the flip positioning frame 1.

[0039] The flip positioning frame 1 is a rectangular structure with an opening on one side. After the panel is placed from the opening side, it is adsorbed and positioned on one side by an adsorption device, and the panel is initially attached and positioned by the flip positioning frame 1.

[0040] A sealing dish 2 is provided on the inner edge of the flip positioning frame 1. The sealing dish 2 is filled with a liquid medium with good flowability. The sealing dish 2 presses against one side of the panel. The sealing dish 2 and the adsorption structure are set on the same side of the panel, which facilitates the application of adhesive and bonding on one side of the panel.

[0041] As the flip positioning frame 1 flips, the panel undergoes a concave deformation from the outside to the inside under the action of gravity. The sealing dish 2, which is in close contact with the panel, tilts accordingly due to the deformation of the panel. The panel deformation data is reflected by the angle between the liquid in the sealing dish 2 and the horizontal plane.

[0042] A float 3 is provided inside the sealing dish 2. The float 3 remains horizontal with respect to the horizontal plane as the liquid medium inside the sealing dish 2 is subjected to gravity. Therefore, there is an angle change between the float 3 and the sealing dish 2. By combining this angle change with the characteristics of the panel material, the deformation of the panel can be accurately calculated.

[0043] An infrared measuring device is fixed on the outer side of the sealing dish 2 corresponding to the float 3. The infrared measuring device emits infrared rays to the float 3 and receives the reflected infrared rays at the float 3. By measuring the distance between the incident beam and the reflected beam, the tilt angle of the liquid medium in the sealing dish 2 is calculated, thereby realizing the accurate measurement of the panel deformation.

[0044] The inner side of the flip positioning frame 1 is equipped with a Mark alignment point 4. The Mark alignment point 4 is a key reference mark used for precise positioning in electronic manufacturing. It is a solid circular mark that provides a coordinate reference for the production of water-based adhesive bonding of the touch screen through an optical recognition system, ensuring the precise alignment of the panel.

[0045] The Mark alignment point 4 is fixedly connected to the traction harness 5. The PCL control system drives the traction harness 5 to pull the Mark alignment point 4 to adjust its positioning based on the measurement data of the infrared measuring equipment. By calculating the deformation of the panel under the influence of gravity, the Mark alignment point 4 of the panel is recalibrated. This enables the equipment to process smaller panels and, in the processing of larger panels, to intelligently adjust the position of the Mark alignment point 4 through the PCL control system.

[0046] A vertical rod 6 is fixed at the midpoint of the side of the float 3. The angle of the vertical rod 6, which is fixed vertically to the float 3, changes synchronously with the displacement of the liquid level in the sealed dish 2.

[0047] A guide rod 7 is fixed to the inner wall of the sealing dish 2 corresponding to the diameter of the upright rod 6. The upright rod 6 is deflected at an angle along the direction of the guide rod 7. The infrared measuring device is installed along the direction of the guide rod 7 corresponding to the upright rod 6 to ensure the installation angle between the infrared measuring device and the upright rod 6, thereby ensuring that the infrared measuring device receives the reflected light from the side of the upright rod 6.

[0048] A reflector 8 is fixed on the side of the upright 6 corresponding to the infrared measuring device. The infrared measuring device is set parallel to the reflector 8. The infrared rays emitted by the infrared measuring device are received by the infrared measuring device after being reflected by the reflector 8. By measuring the distance between the infrared ray emission point and the receiving point, and combining it with the installation distance between the upright 6 and the infrared measuring device, the deflection angle of the upright 6 is calculated.

[0049] A limiting ball 9 is fixed at the end of the upright 6 away from the float 3. The diameter of the limiting ball 9 is larger than the spacing of the guide rod 7, so that when the flip positioning frame 1 is inverted or the upright 6 is deflected, it is always within the limiting range of the guide rod 7. The sealing dish 2 is filled with liquid medium so that the limiting ball 9 floats to a certain height away from the guide rod 7. The deflection angle of the upright 6 is within the accurate measurement range of the infrared measuring device.

[0050] A protrusion 10 is fixed on the side of the float 3 along the extension direction of the traction harness 5. The float 3 is slidably installed inside the sealing dish 2 through the protrusion 10 to avoid the change of the installation angle of the float 3 with the flow of the medium in the sealing dish 2, which would affect the light reflection angle between the float 3 and the infrared measuring device, thus ensuring the accuracy of the measurement data. Furthermore, as the panel deforms under the action of gravity, the protrusion 10 will not affect the angle deflection of the float 3 as it flows with the medium.

[0051] The end of the traction harness 5 is connected to a winding roller 11. The PCL control system winds the traction harness 5 through the winding roller 11 and drives the Mark alignment point 4 to move along the inner wall of the flip positioning frame 1. The PCL control system drives the rotation of the winding roller 11 in a specific direction to wind up the traction harness 5, thereby realizing the movement and traction of the Mark alignment point 4 fixed on the traction harness 5.

[0052] The inner wall of the flip positioning frame 1 is fixed with a guide rail 12 along the diagonal direction. The Mark alignment point 4 is slidably set inside the flip positioning frame 1 through the guide rail 12. The deformation of the panel under the action of gravity will be from the outside to the inside, and the displacement in the diagonal direction is the most obvious. Therefore, the guide rail 12 is set along the diagonal direction to most accurately reflect the degree of deformation.

[0053] The bearing of the roller 11 is located inside the guide rail 12. The two ends of the traction harness 5 are driven by the roller 11 respectively. The rollers 11 at both ends of the traction harness 5 control the Mark alignment point 4 for fixed-point adjustment.

[0054] The inner wall of the edge of the flip positioning frame 1 is fixed with a mounting slide rail 13. A slider 14 is slidably engaged on the inner side of the mounting slide rail 13. The sealing dish 2 is slidably mounted on the inner side of the flip positioning frame 1 via the slider 14. The sealing dish 2, which is slidably mounted via the mounting slide rail 13, not only makes it easy to change angles with the deformation of the panel, but also facilitates the leveling of the sealing dish 2.

[0055] The side of the flip positioning frame 1 is fitted with a sliding rail 13 that passes through and is threaded with a leveling bolt 15. The leveling bolt 15 abuts against the side wall of the slider 14 and is symmetrically arranged. The leveling bolt 15 is used to abut against the slider 14 to adjust the level of the sealing dish 2.

[0056] A clamping block 16 is slidably disposed on the inner side of the slide rail 13 and on the side of the slider 14 away from the leveling bolt 15. A spring 17 is fixed between the slider 14 and the clamping block 16. The clamping block 16 serves as an intermediate medium for the leveling bolt 15 to level the slider 14. It not only buffers the rigid adjustment of the leveling bolt 15, but also ensures that the sealing dish 2 can deflect as the panel deforms.

[0057] Before use, ensure that the reflector 8 inside the sealing dish 2 is aligned with the position of the infrared measuring device on the inner side of the flip positioning frame 1. Adjust and level the dish by using the leveling bolts 15 symmetrically arranged below the sealing dish 2. Rotate the corresponding leveling bolts 15 to push the clamping block 16. The clamping block 16 applies different clamping forces to the corresponding side of the sealing dish 2 through the spring 17 to achieve leveling.

[0058] After completing the equipment calibration, the panel to be processed is placed in the flip positioning frame 1 for support and positioning. Then, the panel is adsorbed from the inside of the flip positioning frame 1 by the adsorption structure. Adhesive is applied by the adhesive covering structure. The flip positioning frame 1 is then flipped to proceed to the next step of panel bonding.

[0059] As the flip positioning frame 1 flips, due to the large size of the panel, the panel is deformed to a certain extent from the outside to the inside under the action of gravity. The positioning between the deformed panel and the panel to be attached below changes. If the panel is still attached according to the previously set alignment marks, there will be a large error and a high defect rate. Therefore, those skilled in the art have made structural improvements based on the existing flip positioning frame 1.

[0060] A mounting slide rail 13 is fixedly installed at the inner corner of the flip positioning frame 1. A clamping block 16 is slidably installed inside the mounting slide rail 13. The clamping block 16 is clamped to the sealing dish 2 by a spring 17. A suitable volume of liquid is injected into the sealing dish 2. The liquid has good fluidity. The sealing dish 2 is clamped to the side of the panel by the spring 17. As the panel deforms, the sealing dish 2 that is in contact with it tilts at an angle, and the liquid in the sealing dish 2 tilts.

[0061] The side wall of the flip positioning frame 1 is symmetrically equipped with leveling bolts 15 corresponding to the clamping block 16. The leveling bolts 15 are used to correct the horizontal position of the clamping block 16. The clamping block 16 then applies different amounts of elastic force to the slider 14 through the spring 17, thereby achieving the leveling and calibration of the sealing dish 2.

[0062] A float 3 is slidably installed inside the sealed dish 2. The float 3 tilts at an angle due to the buoyancy of the liquid. In addition, a vertical rod 6 is fixed at the middle position of the upper surface of the float 3. A reflector 8 structure is fixed on the side of the rod 6. An infrared measuring device is fixed inside the flip positioning frame 1 corresponding to the reflector 8. Infrared rays are emitted to the reflector 8 and received by the infrared measuring device. The deflection angle of the float 3 is calculated by the PLC system. Then, the deformation of the panel is calculated by setting the distance between the infrared measuring device and the reflector 8.

[0063] Inside the sealed dish 2, a guide rod 7 is fixedly installed to guide the deflection direction of the upright rod 6 in the direction of the infrared measuring device. In addition, combined with the protrusion 10 on the side of the float 3, the side reflector 8 is always aligned with the infrared measuring device during the up and down movement of the float 3.

[0064] The end of the upright 6 is also fixed with a limiting ball 9. The diameter of the limiting ball 9 is larger than the spacing of the guide rod 7 to prevent the float 3 from leaving the range of the guide rod 7 under the action of liquid buoyancy when the flip positioning frame 1 flips.

[0065] The PLC system controls the corresponding roller 11 to wind up the traction harness 5 based on the deformation of the panel. The traction harness 5 pulls the Mark alignment point 4, which is fixedly connected to it, to slide along the guide rail 12 to change the positioning of the panel bonding, thereby solving the positioning accuracy problem caused by panel deformation in the application of large-size panel bonding.

[0066] The guide rail 12 is set along the diagonal direction of the flip positioning frame 1. The diagonal distance of the rectangular flip positioning frame 1 is the largest, which corresponds to the largest difference in panel deformation, and the adjustment accuracy is the highest in this direction.

[0067] This fully automatic water-based adhesive bonding production equipment for touch screens incorporates a sealing dish 2 structure on the inner side of the existing flip positioning frame 1, which is pressed against the panel. When the panel deforms under gravity, it causes the sealing dish 2, which is in contact with it, to deflect at an angle. The deformation of the panel is calculated by measuring the angle between the liquid plane inside the sealing dish 2 and the horizontal plane. Then, the PLC system drives the Mark alignment point 4, which is slidably installed inside the flip positioning frame 1, to move in an orientation, changing the alignment point of the panel. The panel is then bonded according to the alignment point after deformation. The equipment automatically calibrates the position of the alignment point according to different panel sizes, enabling the processing and use of large-sized panels.

[0068] The float 3 is vertically fixed to the support rod 6 on its side. When the sealing dish 2 changes angle due to the deformation of the panel, the support rod 6 changes angle with the tilt of the liquid surface. Since the tilt angle of the support rod 6 is measured by reflected infrared light, it is necessary to ensure that the infrared measuring structure corresponds to the reflective sheet 8 on the side of the support rod 6. The guide rod 7 is fixed inside the sealing dish 2 to correspond to the support rod 6, and the float 3 is fixed to the side of the support rod 3 with a protrusion 10 to guide the float 3, so that the float 3 always corresponds to the set angle of the infrared measuring structure when the angle changes. In addition, in order to prevent the float 3 from leaving the range of action of the guide rod 7 when the flipping positioning frame 1 is flipped, a limit ball 9 structure is also fixed at the end of the support rod 6.

[0069] The sealing dish 2 is slidably installed on the inner side of the flip positioning frame 1 via the guide slide rail 12. In addition, the side of the slider 14 used to fix the sealing dish 2 is abutted by the spring 17 and the abutting block 16 is set. The abutting block 16 is then leveled by the symmetrically arranged leveling bolts 15. This not only ensures that the sealing dish 2 deflects at an angle as the panel deforms, but also allows for the calibration and adjustment of the sealing dish 2 and the infrared measuring structure by the symmetrically arranged leveling bolts 15.

[0070] An installation slide rail 13 is set along the diagonal direction on the inner side of the flip positioning frame 1. The Mark alignment point 4 is slidably installed through the installation slide rail 13. The PLC equipment calculates the measurement data of the infrared measuring structure and then controls the rotation of the roller 11 accordingly. The roller 11 is pulled by the traction wire harness 5 to change the position of the Mark alignment point 4 that is slidably set along the installation slide rail 13. Then, according to the different degrees of deformation of the panel of different sizes, the position of the alignment point is changed accordingly to ensure the production accuracy of the equipment for bonding large diameter panels.

[0071] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
