A movable seat one is slidably mounted on the surface of the electromagnetic slide rail one, and the electromagnetic slide rail two is fixedly connected to the movable seat one. A movable seat two is slidably mounted on the surface of the electromagnetic slide rail two. A DD motor is mounted on the upper surface of the movable seat two, a base is mounted above the DD motor, and a film-applying device is mounted above the base. The patching rollers can be driven to rotate by a power source, thereby moving the film. The polarizer is located on the side of the film, so the film can move along with the polarizer.

This achieves the effect of synchronous movement of the two patching rollers, the two films, and the LCD product, enabling simultaneous application of polarizers to both sides of the LCD product.

Description

Technical Field

[0001] This invention belongs to the field of patch technology, and specifically relates to a patching mechanism. Background Technology

[0002] LCD products refer to various electronic products that use Liquid Crystal Display (LCD) technology. LCD products typically consist of two parallel glass plates filled with liquid crystal material. When an electric current passes through the liquid crystal, the liquid crystal molecules rearrange themselves, refracting light to form an image. By controlling the magnitude and direction of the current, the arrangement of the liquid crystal molecules can be precisely controlled, thereby achieving image display and changes. Common LCD products include television screens, computer monitors, mobile phone screens, tablet computers, and automotive displays. A polarizer, or polarizing film, is essential for the imaging of liquid crystal displays. All liquid crystals have two polarizing films, one at the front and one at the back, attached tightly to the liquid crystal glass, forming a liquid crystal sheet with a total thickness of approximately 1 mm.

[0003] Common bonding mechanisms use movable bonding rollers to push polarizers onto the surface of LCD products. However, polarizers can only be bonded to one side at a time. If both sides need to be bonded simultaneously, the overall length of the equipment will be much longer. Summary of the Invention

The tension cylinder has a tension roller installed at its end, and a lead screw module is installed at the output end of the motor. A movable frame is slidably installed inside the slide rail, and a movable frame is slidably connected to the side of the movable frame. The movable frame and the lead screw module are threadedly engaged. An electro-proportional valve is installed on the side of the movable frame. The end of the application cylinder is connected to the movable frame. The application roller is installed inside the movable frame and can be driven to rotate by a power source. The application cylinder and the separating roller are both installed on the side of the movable frame.

[0007] The support mechanism includes a support frame and support rollers. The support rollers are movably connected to the support frame's rotating shaft and are symmetrically arranged.

[0008] Preferably, the conveying mechanism includes a second motor, a driving roller, a driven roller, and a first transmission belt. The transmission belt is fitted onto the surfaces of the driving roller and the driven roller. A connecting shaft is connected to the side of the driven roller. A roller is connected inside the connecting shaft. A roller body is connected to the surface of the roller. The second transmission belt is fitted onto the surface of the roller.

[0009] Preferably, there are two sets of electromagnetic slide rail one, electromagnetic slide rail two, movable seat one, movable seat two, DD motor, base and film application device, and they are arranged symmetrically.

[0010] Preferably, an extension block is fixedly mounted on the surface of the slide rail, and a limit roller is rotatably mounted inside the extension block.

[0012] Preferably, the sheet passes over the surfaces of the fixing roller, separating roller, tensioning roller and attaching roller, and its ends are clamped and fixed by a membrane clamp.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The application mechanism, through the setting of electromagnetic slide rail one, allows the moving seat one, electromagnetic slide rail two, moving seat two, DD motor, base and film application device to move along electromagnetic slide rail one in the X-axis direction. Similarly, electromagnetic slide rail two facilitates the movement of moving seat two, DD motor, base and film application device in the Y-axis direction, thereby facilitating the adjustment of the distance between the film application device and the support mechanism. DD motor facilitates the rotation of base and film application device, thereby changing the angle of film application device.

[0015] 2. This bonding mechanism, through the setting of the tensioning cylinder, facilitates the adjustment of the position of the tensioning roller, thereby making it easier to support and adjust the tightness of the sheet. The setting of the fixed roller and the separation roller facilitates the sheet to bypass, thus forming a certain path for the sheet. The end of the sheet can be fixedly connected through the film clamp plate. Motor 1 can drive the lead screw module to rotate, and the lead screw module can drive the moving frame 1 to translate along the slide rail in the X-axis direction according to the lead screw motion principle, which is conducive to adjusting the position of the bonding roller and the separation roller. The bonding cylinder can drive the moving frame 2 to move in the Y-axis direction. The electric proportional valve controls the air pressure of the bonding cylinder through electrical signals, which can achieve the purpose of fine adjustment of the position of the bonding roller and the purpose of consistent pressure of the two symmetrical bonding rollers. The bonding roller can be driven to rotate by the power source, thereby driving the sheet to move. The polarizer is located on the side of the sheet, so the sheet can move the polarizer together.

[0016] 3. This attachment mechanism, through the cooperation of the support mechanism and the conveying mechanism, helps to ensure the vertical placement of the LCD product and its synchronous movement with the thin film, allowing the LCD product to pass between symmetrical thin films. This achieves the effect of synchronous movement of the two attachment rollers, the two thin films, and the LCD product, enabling the simultaneous attachment of polarizing films to both sides of the LCD product.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0024] Please see Figure 1-4 The present invention provides the following technical solution: an attachment mechanism, including an electromagnetic slide rail 1, an electromagnetic slide rail 2, a support mechanism 6 and a conveying mechanism 7. A movable seat 9 is slidably mounted on the surface of the electromagnetic slide rail 1. The electromagnetic slide rail 2 is fixedly connected to the movable seat 9. A movable seat 10 is slidably mounted on the surface of the electromagnetic slide rail 2. A DD motor 3 is mounted on the upper surface of the movable seat 10. A base 4 is mounted above the DD motor 3. A film attaching device 5 is mounted above the base 4. An LCD product 8 is provided inside the support mechanism 6.

[0025] The film application device 5 includes a frame body 5-15, a tension cylinder 5-1, an application cylinder 5-2, a fixing roller 5-3, a separating roller 5-4, a motor 5-5, a film clamping plate 5-6, a film sheet 5-7, a polarizing film 5-8, a slide rail 5-9, and an application roller 5-11. A tension roller 5-10 is installed at the end of the tension cylinder 5-1. A lead screw module 5-12 is installed at the output end of the motor 5-5. A movable frame 5-13 is slidably installed inside the slide rail 5-9. A movable frame 5-16 is slidably connected to the side of frame 1 5-13. The movable frame 1 5-13 and the lead screw module 5-12 are threadedly engaged. An electric proportional valve 5-14 is installed on the side of movable frame 1 5-13. The end of the attachment cylinder 5-2 is connected to movable frame 2 5-16. The attachment roller 5-11 is installed inside movable frame 2 5-16 and can be driven to rotate by a power source. The attachment cylinder 5-2 and the separation roller 5-4 are both installed on the side of movable frame 1 5-13.

[0026] The support mechanism 6 includes a support frame 6-1 and a support roller 6-2. The support roller 6-2 is movably connected to the support frame 6-1 via a rotating shaft, and the support roller 6-2 is symmetrically arranged.

[0027] In this embodiment, by setting electromagnetic slide rail 1, the movable seat 9, electromagnetic slide rail 2, movable seat 10, DD motor 3, base 4, and film application device 5 can move along electromagnetic slide rail 1 in the X-axis direction. Similarly, electromagnetic slide rail 2 facilitates the movement of movable seat 10, DD motor 3, base 4, and film application device 5 in the Y-axis direction, thereby facilitating the adjustment of the distance between film application device 5 and support mechanism 6. DD motor 3 facilitates the rotation of base 4 and film application device 5, thereby changing the angle of film application device 5. The tension cylinder 5-1 is also used for this purpose. The position of the tension roller 5-10 is designed to facilitate the adjustment of the tension of the sheet 5-7. The fixed roller 5-3 and the separating roller 5-4 allow the sheet 5-7 to easily navigate around the tension roller, thus forming a specific path. The end of the sheet 5-7 can be fixedly connected via the membrane clamp 5-6. The motor 5-5 drives the lead screw module 5-12 to rotate, which in turn drives the movable frame 5-13 to translate along the slide rail 5-9 in the X-axis direction according to the lead screw motion principle. This facilitates the adjustment of the attachment roller 5-11 and the separating roller. The position of wheel 5-4 allows the attachment cylinder 5-2 to move the moving frame 5-16 along the Y-axis. The electro-proportional valve 5-14 controls the air pressure of the attachment cylinder 5-2 via an electrical signal, achieving fine-tuning of the position of the attachment roller 5-11 and ensuring consistent pressure between the two symmetrical attachment rollers 5-11. The attachment roller 5-11 can be driven to rotate by a power source, thus moving the sheet 5-7. The polarizer 5-8 is located to the side of the sheet 5-7, allowing the sheet 5-7 to move along with the polarizer 5-8. This is achieved through the cooperation of the support mechanism 6 and the conveying mechanism 7. This helps ensure the vertical placement of the LCD product 8 and its synchronous movement with the thin sheets 5-7, allowing the LCD product 8 to pass between the symmetrical thin sheets 5-7. This achieves the effect of synchronous movement of the two attachment rollers 5-11, the two thin sheets 5-7, and the LCD product 8, enabling the simultaneous attachment of polarizers 5-8 to both sides of the LCD product 8. In addition, since the polarizers 5-8 are pre-attached to the side of the thin sheets 5-7 and the thin sheets 5-7 are in a taut state, the polarizers 5-8 are less likely to lift or be suspended, thus preventing air bubbles from forming during attachment.

[0028] Specifically, the conveying mechanism 7 includes a second motor 7-1, a driving roller 7-2, a driven roller 7-3, and a first transmission belt 7-4. The first transmission belt 7-4 is fitted onto the surfaces of the driving roller 7-2 and the driven roller 7-3. A connecting shaft 7-5 is connected to the side of the driven roller 7-3. A roller 7-6 is connected inside the connecting shaft 7-5. A roller body 7-7 is connected to the surface of the roller 7-6. The second transmission belt 7-8 is fitted onto the surface of the roller 7-6. The second motor 7-1 can drive the driving roller 7-2 to rotate. The driving roller 7-2 drives the driven roller 7-3 to rotate through the first transmission belt 7-4. In turn, the driven roller 7-3 drives the connecting shaft 7-5 and the roller 7-6 to roll. The second transmission belt 7-8 is fitted onto the surfaces of two adjacent rollers 7-6. Therefore, the second transmission belt 7-8 can drive all rollers 7-6 to roll. The rollers 7-6 will drive the roller body 7-7 to roll, which is beneficial for conveying symmetrically placed vertically LCD products 8.

[0029] Specifically, there are two sets of electromagnetic slide rail 1, electromagnetic slide rail 2, movable seat 1 9, movable seat 2 10, DD motor 3, base 4 and film application device 5, which are symmetrically arranged. The symmetrically arranged devices are located on both sides of the conveying mechanism 7, the support mechanism 6 and the LCD product 8.

[0030] Specifically, an extension block 11 is fixedly installed on the surface of the slide rail 5-9. A limiting roller 12 is rotatably installed inside the extension block 11. The limiting roller 12 helps to limit the sheet 5-7, making it easier for the sheet 5-7 to pass over and be tensioned from the surfaces of the fixed roller 5-3, the separating roller 5-4, the tensioning roller 5-10 and the attaching roller 5-11.

[0031] Specifically, tension cylinder 5-1, motor 5-5, slide rail 5-9, and fixed roller 5-3 are all installed on frame body 5-15. Frame body 5-15 is connected to base 4, so that the film application device 5 can not only be driven by DD motor 3 to adjust the angle, but also be driven by electromagnetic slide rail 2 and moving frame 2 5-16 to move in the Y-axis direction.

[0032] Specifically, the sheet 5-7 passes over the surfaces of the fixing roller 5-3, the separating roller 5-4, the tensioning roller 5-10, and the attaching roller 5-11, forming a certain travel path. The tension of the sheet 5-7 can be adjusted by the tensioning roller 5-10, and its end is clamped and fixed by the membrane clamp 5-6. The membrane clamp 5-6 is detachable and mainly allows the two ends of the sheet 5-7 to be connected.

[0033] The working principle and usage process of this invention: Before use, the polarizer 5-8 can be pre-attached to the side of the thin film 5-7. Then, by activating the electromagnetic slide rail 1, the interaction of current and magnetic field generates propulsion, allowing the moving base 9, electromagnetic slide rail 2, moving base 10, DD motor 3, base 4, and film application device 5 to move along the electromagnetic slide rail 1 in the X-axis direction. Similarly, the electromagnetic slide rail 2 facilitates the movement of the moving base 10, DD motor 3, base 4, and film application device 5 in the Y-axis direction, thereby facilitating the adjustment of the distance between the film application device 5 and the support mechanism 6. By controlling the DD motor 3... The base 4 and film-applying device 5 are steered, allowing the angle of the film-applying device 5 to be changed. Controlling the tension cylinder 5-1 helps adjust the position of the tension roller 5-10, facilitating the support and adjustment of the tension of the sheet 5-7. The fixing roller 5-3 and separating roller 5-4 allow the sheet 5-7 to pass around, thus forming a specific running path. The end of the sheet 5-7 can be fixedly connected via the film clamp 5-6. Starting the motor 5-5 drives the lead screw module 5-12 to rotate, which, according to the lead screw motion principle, drives the moving frame 5-13 along the slide rail 5-1. 9. Translation along the X-axis facilitates adjustment of the positions of the attachment roller 5-11 and the separation roller 5-4. Controlling the attachment cylinder 5-2 drives the moving frame 5-16 to move along the Y-axis. The electro-proportional valve 5-14 controls the air pressure of the attachment cylinder 5-2 via an electrical signal, achieving fine-tuning of the position of the attachment roller 5-11 and ensuring consistent pressure between the two symmetrical attachment rollers 5-11. The attachment roller 5-11 can be driven to rotate by a power source, thereby moving the sheet 5-7. The polarizer 5-8 is located to the side of the sheet 5-7, allowing the sheet 5-7 to move along with the polarizer 5-8. This is achieved through support... The cooperation between mechanism 6 and conveying mechanism 7 helps to ensure the vertical placement of LCD product 8 and its synchronous movement with the thin sheets 5-7, allowing LCD product 8 to pass between the symmetrical thin sheets 5-7. This achieves the effect of synchronous movement of the two attaching rollers 5-11, the two thin sheets 5-7, and LCD product 8, enabling the simultaneous attachment of polarizing films 5-8 to both sides of LCD product 8. In addition, since the thin sheets 5-7 are in a taut state, the polarizing films 5-8 are less likely to lift or be suspended, thus preventing air bubbles from forming during attachment. The input terminals of the electrical equipment in this device are all electrically connected to an external power source.
