Abstract
Description
Technical Field
[0001] This application relates to the field of lens bonding technology, and in particular to an automatic lens dispensing and assembly equipment and its assembly system. Background Technology
[0002] LCD (short for Liquid Crystal Display) is a liquid crystal display. The structure of an LCD is to place a liquid crystal cell between two parallel glass substrates. TFTs (Thin Film Transistors) are set on the lower glass substrate, and color filters are set on the upper glass substrate. By changing the signals and voltages on the TFTs, the rotation direction of the liquid crystal molecules is controlled, thereby controlling whether polarized light is emitted from each pixel to achieve the display purpose.
[0003] As a mobile display model used in digital clocks and many portable computers, LCD screens require a dispensing process during production to ensure quality. The dispensing and assembly of LCD screens demands high precision and must be performed in a dust-free environment to guarantee production quality. Currently, the manufacturing cost of existing LCD lenses is often relatively high, and during automated production, the equipment itself is prone to scratching the LCD lenses, leading to uneven dispensing, a high scrap rate, and reduced overall LCD screen manufacturing quality, resulting in the LCD lenses failing to meet production precision requirements.
[0004] Due to the immaturity of existing dispensing equipment, most LCD screen production and assembly processes still rely on a combination of manual labor and equipment. Furthermore, the high precision required for assembling LCD lenses necessitates workers operating under microscopes to continuously adjust the lens positions to ensure accuracy. Before bonding the lenses, manual dispensing of adhesive is required, with meticulous control over the amount to prevent over-dispensing. This necessitates careful control of the adhesive amount during operation; otherwise, excessive adhesive overflow can render the assembled LCD screen unusable. As market demand for LCD screens continues to grow, the inefficiency of manual assembly is completely unsustainable.

[0045] Example 1
[0046] In this embodiment, to automate the production and processing of LCD screens, improve the accuracy of upper and lower substrate glass bonding and assembly, and ensure product quality, an automatic lens dispensing and assembly device is proposed. This device can effectively perform high-precision bonding of upper and lower substrate glass. Specifically, this embodiment includes a first linear module, a second linear module, a bonding platform, and a correction mechanism. By placing the correction mechanism between the first linear module and the bonding platform, the upper substrate glass can be aligned before bonding, ensuring bonding accuracy. Furthermore, by positioning the second linear module above the first linear module and ensuring that the movement direction of the first linear module is perpendicular to the movement direction of the second linear module, the device effectively ensures convenience for workers when loading or unloading materials, significantly improving operational ease, and ensuring that the upper substrate glass can be smoothly transferred to the bonding platform during transport.
[0047] To ensure high-precision bonding of the upper and lower substrate glass, this example includes a position adjustment mechanism and a mounting tray for placing the lower substrate glass on the mounting platform. The position adjustment mechanism adjusts the placement of the mounting tray to adjust the lower substrate glass. Additionally, the linear guide rail of the first linear module has a lens tray for placing the upper substrate glass, and the linear guide rail of the second linear module has a dispensing connector and an assembly nozzle. The dispensing connector dispenses adhesive onto the lower substrate glass, and the assembly nozzle picks up, aligns, and moves the upper substrate glass onto the lower substrate glass for precise attachment. To prevent the upper substrate glass from shifting during transport, the correction groove of the correction mechanism and the suction plane of the assembly nozzle are aligned vertically, avoiding the need for the upper substrate glass to move at other angles and ensuring precise alignment with the lower substrate glass. For example:
[0048] By fixing the upper substrate glass lens holder to the lens holder placed on the first linear module, and simultaneously fixing the lower substrate glass mounting holder to the mounting holder on the adjacent mounting platform, the mounting holder is rotated and adjusted by the position adjustment mechanism, thereby adjusting the position of the lower substrate glass on the mounting holder; and the lens holder on the other side is transported to below the assembly nozzle by the first linear module, and the upper substrate glass on the lens holder is adsorbed and transported to the alignment mechanism by the assembly nozzle, where the lens groove on the alignment mechanism aligns the upper substrate glass with the lower substrate glass; and in After the dispensing connector is adjusted, adhesive is dispensed onto the surface of the lower substrate glass through the dispensing connector. After dispensing is completed, the lower substrate glass on the mounting tray is pushed to the bottom of the second linear module by the position adjustment mechanism. The upper substrate glass, which has been corrected by the correction mechanism, is then adsorbed and transported by the assembly nozzle, so that the upper substrate glass can be moved directly above the lower substrate glass. Then, the upper substrate glass is aligned and attached to the surface of the lower substrate glass by pressing down with the assembly nozzle. This achieves automated high-precision attachment and assembly of the upper and lower substrate glass, improves the efficiency and accuracy of lens assembly, reduces the scrap rate of LCD screen assembly, and thus ensures the production quality of lens assembly.
[0049] It should be noted that the various linear modules in this example have several names, such as linear module, Cartesian coordinate robot, linear slide, etc., and are automation upgrade units following linear guides, linear motion modules, and ball screw linear transmission mechanisms. Linear and curvilinear motion of loads can be achieved through the combination of various units, making automation of light loads more flexible and positioning more precise. Linear modules are used in loading and unloading robots, cutting and transferring equipment, gluing equipment, and patching equipment, and are widely used in measurement, laser welding, laser cutting, gluing machines, spraying machines, drilling machines, dispensing machines, small CNC machine tools, engraving and milling machines, sample drawing machines, cutting beds, transfer machines, sorting machines, testing machines, and educational settings. Currently, the widely used linear modules can be divided into three types: synchronous belt type, ball screw type, and linear motor type. Among them, the synchronous belt type linear module is mainly composed of belt, linear guide, aluminum alloy profile, coupling, motor, photoelectric switch, etc.; the ball screw type linear module is mainly composed of ball screw, linear guide, aluminum alloy profile, ball screw support, coupling, motor, photoelectric switch, etc.
[0050] Example 2
[0051] In this embodiment, to specifically implement the above-mentioned technical content, further description is provided to facilitate understanding of the technical solution of this application. Specifically, the position adjustment mechanism is used to adjust the position of the patch tray, and in fact, it adjusts in three directions. The position adjustment mechanism consists of components such as an X-axis control module, a Y-axis control module, a tray mounting plate, and a hollow shaft rotating platform. The tray mounting plate is fixed to the table surface of the hollow shaft rotating platform to place the lower substrate glass. Then, the hollow shaft rotating platform is fixed to the... The X-axis control module is fixed to the Y-axis sliding plate of the Y-axis control module, and the sliding direction of the Y-axis sliding plate is perpendicular to the movement direction of the second linear module. This enables three-way adjustment of the patch tray, wherein the patch tray is axially rotated by a hollow shaft rotating platform, the patch tray is adjusted in the X-axis direction by the X-axis sliding plate of the X-axis control module, and the patch tray is adjusted in the Y-axis direction by the Y-axis sliding plate of the Y-axis control module, thereby achieving adjustment and control in three directions.
[0052] In addition, to achieve precise dispensing of adhesive to the lower substrate glass, this example also includes a vertical linear module, a dispensing syringe, and a position probe on the dispensing connector. A sliding mounting plate is provided on the outer side of the vertical linear module. By fixing the ball screw of the vertical linear module to one end of the sliding mounting plate, the vertical linear module provides power to the sliding mounting plate, enabling it to slide in the vertical direction. Simultaneously, the vertical linear module is fixed to the linear guide rail of the second linear module through a connecting component, and the dispensing syringe and the position probe are both fixed on the sliding mounting plate, with both the dispensing syringe and the position probe facing the surface of the mounting platform. This allows it to align with the lower substrate glass for dispensing and to adsorb and move the upper substrate glass. The position of the lower substrate glass is detected and determined by the position probe, achieving precise dispensing and preventing incorrect dispensing of the lower substrate glass that could lead to scrap.
[0053] Corresponding to the dispensing connector is the assembly nozzle, which, in order to achieve precise adsorption and transfer of the upper substrate glass, is configured in this example with a nozzle linear module, a vacuum nozzle head, a suction plate support, and a suction plate probe. A spring sliding plate is installed on the outside of the nozzle linear module, and the ball screw of the nozzle linear module is fixedly connected to one end of the spring sliding plate, thereby controlling the movement of the spring sliding plate. After bonding, the spring on the spring sliding plate returns to its original position, allowing for continuous transfer and bonding of the upper substrate glass. The nozzle linear module is fixed to the linear guide rail of the second linear module by a mounting plate. The second linear module simultaneously controls the movement of the dispensing connector and the assembly nozzle, saving power while effectively controlling the movement of the dispensing connector and the assembly nozzle synchronously. In this example, the suction bracket is fixed to the vacuum suction head, and the suction hole of the vacuum suction head is connected to the through hole of the suction bracket, so that the suction bracket and the suction probe face the lens holder. The position of the upper substrate glass is determined by the suction probe, and then the upper substrate glass is smoothly adsorbed by the suction bracket. The second linear module moves to place the upper substrate glass on the correction structure for alignment, and then moves it above the bonding tray for bonding.
[0054] It should also be noted that the above-mentioned correction mechanism is composed of a correction linear module and a correction plate, etc. In this example, the correction plate is fixed on the linear guide rail of the correction linear module by a connecting plate, and the correction plate is provided with a correction groove, which is adapted to the shape of the lower substrate glass. In this example, the movement direction of the correction linear module is set to be perpendicular to the movement direction of the second linear module. In actual application, the upper substrate glass is placed from the assembly nozzle into the correction groove, and then the correction linear module controls the shaking (back and forth movement) of the correction plate so that it can fit perfectly on the correction groove, correcting the upper substrate glass and ensuring that the upper substrate glass can be accurately aligned with the lower substrate glass for easy bonding.
[0055] It is worth noting that in practical applications, to facilitate simultaneous control of the assembly nozzle and dispensing connector on the second linear module and improve lens bonding efficiency, this example also requires that the assembly nozzle be positioned closer to the first linear module and the dispensing connector be positioned closer to the bonding platform. The second linear module synchronously controls the sliding of the dispensing connector and the assembly nozzle. Specifically, by setting the distance between the dispensing connector and the assembly nozzle to be equal to the distance between the lens holder and the bonding holder, when the assembly nozzle on one side is controlled by the second linear module to move, the dispensing connector on the other side remains above the bonding holder, enabling dispensing of adhesive to the lower substrate glass on it and improving the assembly efficiency.
[0056] Example 3
[0057] In this embodiment, when adjusting the angle and position of the patch tray, to ensure the accuracy of the bonding, it is necessary to ensure the stability of the underlying substrate glass and the flatness of the patch tray. This example also requires limiting the components controlling its direction to ensure that the underlying substrate glass does not shift during the adjustment process, thus ensuring the quality of the bonding. For example, this example sets a third linear module and a first sliding guide rail on the Y-axis control module, and makes the first sliding guide rail parallel to the movement direction of the third linear module to ensure consistency of the adjustment direction. In addition, to ensure smoothness and flatness, this example also provides a power slider and a guide slider on the bottom surface of the Y-axis sliding plate. By fixing the power slider to the linear guide rail of the third linear module and sliding the guide slider to the first sliding guide rail, the movement direction of the third linear module can be parallel to the movement direction of the second linear module, ensuring that the patch tray is flat during position adjustment and that the underlying substrate glass does not shift.
[0058] Correspondingly, the adjustment of the other direction of its position adjustment mechanism is also based on the same principle. In this example, a fourth linear module and a second sliding guide are set on the X-axis control module. By fixing both the fourth linear module and the second sliding guide on the surface of the Y-axis sliding plate, the second sliding guide can be parallel to the movement direction of the fourth linear module. Under the premise of ensuring that the entire structure is flat, a push slider and an X-axis slider are set on the bottom surface of the X-axis sliding plate. By fixing the push slider on the linear guide of the fourth linear module and sliding the X-axis slider on the second sliding guide, the adjustment of the X-axis direction is realized, thereby realizing the control of the X-axis direction, Y-axis direction and rotation direction. This ensures that the lower substrate glass can be adjusted in multiple dimensions, thereby ensuring the accuracy of the bonding.
[0059] In addition, to achieve coordination between the patching platform and the lens tray, so that staff can promptly remove the lenses after patching and remove the used upper substrate glass tray, the movement direction of the first linear module is set to be parallel to the movement direction of the third linear module, and the patching tray and the lens tray are located on the same plane. At the same time, the second linear module is positioned directly above the ends of the first linear module and the third linear module, ensuring the accuracy of lens patching while also facilitating lens handling by the user.
[0060] Corresponding to the aforementioned application function implementation method embodiments, this application also provides an automatic lens dispensing and assembly system and corresponding embodiments.
[0061] This automated lens dispensing and assembly system includes:

[0063] Example 4
[0064] In this embodiment, to achieve bonding of the upper and lower substrate glass, a control module and an image sensor are introduced. The image sensor is a CCD camera, i.e., a charge-coupled device camera. By placing the image sensor directly below the correction mechanism, directly above the bonding platform, and above the lens holder, each step of the upper and lower substrate glass is monitored and judged. The image sensor acquires the image of the lens, and compares it with the image of the upper substrate glass. If the pairing does not match, the bonding platform is adjusted. If the pairing matches, the assembly nozzle is directly controlled to perform bonding.
[0065] In practical applications, by electrically connecting the control module to the three image sensors, the first linear module, the second linear module, the position adjustment mechanism, the dispensing connector, and the assembly nozzle, the control module controls the movement of the first linear module, the second linear module, and the position adjustment mechanism according to the data signals emitted by the image sensors after judgment, and controls the movement of the dispensing connector and the assembly nozzle according to instructions, thereby achieving automatic and precise lens bonding.
