Description

Technical Field

[0001] This invention relates to the field of glass transfer technology, specifically to a fully automatic glass transfer control method and apparatus. Background Technology

[0002] Currently, with the rapid growth in demand for display panels, architectural decorative glass, and high-end packaging glass, glass surface transfer technology has become one of the core processes for achieving complex textures, high-precision patterns, and OLED-like display effects. However, existing technologies still have significant shortcomings in multi-parameter collaborative control, automation precision, and process adaptability, which restrict further improvements in production efficiency and product quality. Traditional screen printing or thermal transfer equipment mostly uses mechanical positioning or semi-automatic correction methods, making it difficult to achieve high-precision alignment. For example, insufficient stability of the chain drive structure can lead to misregistration in multi-color printing, requiring manual intervention to adjust the angle, resulting in a high defect rate. In addition, in existing coating processes, parameters such as doctor blade pressure, ink viscosity, and temperature are mostly set based on experience and lack dynamic adjustment mechanisms.

[0056] 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.

[0057] It should be noted that the terms "first," "second," "third," "fourth," etc., in the specification and claims of this invention are used to distinguish different objects, not to describe a specific order. The terms "comprising" and "having," and any variations thereof, in the embodiments of this invention are intended to cover non-exclusive inclusion. Exemplarily, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0058] This invention discloses a fully automated glass transfer control method, device, electronic equipment, and storage medium. In this embodiment, a process parameter database is established by automatically analyzing glass parameters and transfer parameters, achieving full-process parameter matching, reducing manual trial-and-error time. Edge image information of the target glass is collected for centering, and a CCD vision system automatically corrects the positioning, replacing manual adjustment for greater accuracy. Ink viscosity and temperature are monitored and adjusted in real time to ensure ink quality. The coating blade pressure is set based on the glass surface roughness to perform UV screen printing on the target glass, and the current ink layer thickness is collected in real time, greatly improving coating efficiency, ink utilization, and ensuring coating quality and accuracy. The coated target glass is then conveyed to the printing station, where the pressure roller pressure is adjusted based on the film texture depth and glass thickness to imprint the texture on the film onto the target glass. This completes the coordinated dynamic control of printing and UV curing, achieving efficient printing while ensuring printing precision and reducing the defect rate.

[0059] Example 1

[0060] Please see Figure 1 , Figure 1This is a flowchart illustrating the fully automated glass transfer control method disclosed in this invention. The execution entity of the method described in this embodiment is an execution entity composed of software and / or hardware. This execution entity can receive relevant information via wired or / or wireless means and can send certain instructions. It may also have certain processing and storage functions. This execution entity can control multiple devices, such as remote physical servers or cloud servers and related software, or local hosts or servers and related software that perform related operations on devices located in a certain location. In some scenarios, it can also control multiple storage devices, which may be placed in the same location as the devices or in different locations. Figure 1 As shown, the fully automated glass transfer control method includes the following steps:

[0061] 101. In response to the glass transfer instruction, obtain the glass parameters and transfer parameters in the glass transfer instruction. The glass parameters include glass size, glass thickness, and glass surface roughness. The transfer parameters include coating ink viscosity, coating ink temperature, and coating ink layer thickness.

[0062] In the embodiments, as shown Figure 4 and Figure 5 As shown, there are a total of four stations. One station is the film feeding and positioning station 1, where the target glass is conveyed in and precisely positioned. Another station is the coating station 2, which is used for one-to-one alignment screen printing UV coating. Another station is the imprinting station 3, which is used for imprinting and curing. The third station is the film transfer station 4, which is used to transfer the transferred target glass out. The glass is automatically lifted and transported back and forth by the guide rail under the platform.

[0063] The glass transfer instruction is used to initiate the system process. This instruction may be manually entered or automatically triggered by the system upon meeting certain conditions. Glass dimensions typically refer to the glass area.

[0064] 102. Grab the target glass and transfer it to the positioning station. Collect the edge image information of the target glass, calculate the center coordinates of the target glass, define the center position of the positioning station as the origin of the coordinates, calculate the deviation vector between the center coordinates and the origin of the coordinates, and when the deviation vector is greater than a set threshold, correct the position of the target glass so that the target glass is located in the center position of the positioning station.

[0065] First, the target glass is cleaned and conveyed to the positioning station. A servo motor centers the glass, and the initial guide rail extends, its suction cups holding and lifting the glass. The guide rail moves the glass to the second station for screen printing and UV coating. The guide rail then lowers the glass, and the platform automatically holds it in place using suction to ensure its position remains unchanged. The guide rail returns to its initial position, and the same process is repeated.

[0066] In the positioning phase, the embodiment employs visual correction. A positional deviation threshold is set for the vision system, and a feedback control algorithm for the servo motor, such as a PID algorithm, is used to correct the glass position. Specifically, the center coordinates of the target glass are calculated as (Xa, Ya), and the center position of the positioning station is defined as the origin (0,0). The X-axis deviation vector and Y-axis deviation vector are calculated respectively, where the X-axis deviation vector ΔX = Xa - 0 and the Y-axis deviation vector ΔY = Ya - 0. It is then determined whether the X-axis deviation vector and / or the Y-axis deviation vector are greater than the set threshold. Furthermore, when the deviation vector is greater than a set threshold, the target glass position is corrected so that the target glass is located in the center of the positioning station. This includes: when the deviation vector is greater than the set threshold, controlling the position adjustment motor to drive the shifting component to move the target glass to the target area at the maximum value of the set speed range so that the deviation vector is less than or equal to the set threshold; calculating the current deviation vector; when the current deviation vector is greater than the adjustment threshold, controlling the position adjustment motor to drive the shifting component to move the target glass in the X-axis direction and / or Y-axis direction at a closed-loop adjustment speed until the current deviation vector is less than the adjustment threshold, at which point the correction is complete, defined as the target glass being located in the center of the positioning station.

[0067] For example, after the target glass is positioned, the initial deviation ΔX = 0.8mm and ΔY = -0.3mm are measured. At this point, the X-axis deviation is greater than the set threshold, and the coarse positioning correction stage begins. The X-axis is controlled to move at a maximum speed of 50mm / s. Within 0.8mm / 50mm / s = 0.016s, it enters the fine positioning range. Within the fine positioning range, after closed-loop adjustment, the X-axis deviation decreases from 0.8mm to 0.4mm to 0.15mm to 0.05mm, falling below the adjustment threshold. At this point, it is very close to zero, and the setting is considered met, meaning the correction is complete. Through this automatic feedback correction method, the position of the target glass can be accurately positioned, and the positioning correction speed is fast, ensuring that the glass is accurately centered in high-speed production lines, meeting the high-precision manufacturing requirements of automotive display panels, etc.

[0068] 103. Transfer the target glass to the coating station, monitor the ink viscosity and ink temperature in real time, and adjust the ink viscosity and ink temperature. Set the coating blade pressure based on the glass surface roughness to screen print UV coating on the target glass, and collect the current coating ink layer thickness in real time. Stop the blade operation when the current coating ink layer thickness meets the coating ink layer thickness requirements.

[0069] In this step, the system guide rail lowers the glass, and the platform uses suction to hold the glass in place, ensuring its position remains unchanged. Screen printing and UV coating are then performed, and the guide rail returns to its initial position after coating is complete.

[0070] Viscosity reflects the internal friction (cohesion) of a fluid. Ink viscosity is the "core control valve" of the printing process, requiring dynamic adjustment based on substrate characteristics (such as glass roughness), printing method, and environmental conditions. Precise viscosity control significantly improves printing efficiency, reduces waste (such as ink splatter and reprinting), and ensures that the final product meets industry standards (such as ISO 2846-1) in terms of adhesion, color saturation, and durability. For high-precision applications (such as automotive display panels), viscosity fluctuations must be controlled within ±5% to ensure consistent OLED-like display effects.

[0071] In this embodiment, real-time monitoring and adjustment of ink viscosity and temperature includes: acquiring the current ink viscosity using a viscosity sensor and the current ink temperature using a temperature sensor; performing average filtering on the acquired current ink viscosity and temperature; comparing the viscosity difference between the current ink viscosity and a set ink viscosity threshold; when the viscosity difference is greater than the set value, calculating a temperature adjustment amount based on the ratio between the viscosity difference and a temperature sensitivity coefficient, i.e., the temperature adjustment amount equals the viscosity difference divided by the temperature sensitivity coefficient; and adjusting the current ink temperature based on the temperature adjustment amount.

[0072] This step, during the coating stage, allows for precise control of ink viscosity stability by adjusting ink viscosity and temperature. Dynamic distribution of ink temperature is achieved by adjusting ink viscosity, reducing energy consumption and maintaining the working performance of UV inks, thus ensuring screen printing transfer quality. This is suitable for high-precision display panel manufacturing scenarios.

[0073] In this step, in addition to precisely controlling and adjusting the ink viscosity and temperature, the coating blade pressure is monitored and controlled based on feedback. The coating blade pressure is automatically adjusted according to the roughness of the glass surface to ensure uniform ink coating. Furthermore, the blade speed is adjusted based on the thickness of the ink layer. When the blade stops working, the coating process is complete.

[0074] Specifically, the coating blade pressure is automatically adjusted based on the glass surface roughness using the formula P2 = k3·Ra + k4·Ra 2 +Pa calculates the target pressure and adjusts the coating blade pressure to the target pressure so that the coating blade performs screen printing UV coating on the target glass at the target pressure. Here, P2 is the target pressure, Ra is the glass surface roughness, Pa is the preset base pressure of the blade, k3 is the linear response coefficient of the coating blade pressure to the glass surface roughness, and k4 is the nonlinear coefficient for correcting the coating blade pressure under high roughness.

[0075] In the above, the glass surface roughness data is obtained directly through the glass transfer command. Specifically, it can be obtained by scanning the glass surface to acquire three-dimensional morphology data, or by measuring it with a contact roughness instrument. The roughness measurement can be initiated before the target glass enters the positioning station, thus obtaining the glass surface roughness in advance. K3, K4, and P2 are pre-set according to different glass materials. K3 represents the linear effect of unit roughness (Ra value) on the squeegee pressure; for example, K3 = 0.2 N / µm. Specifically, for every 1 micrometer (μm) increase in roughness (Ra value), the squeegee pressure needs to increase by 0.2 Newtons (N) to ensure that the ink fully fills the microscopic uneven structure of the glass surface, while avoiding uneven coating or insufficient ink penetration. Its core function is to convert microscopic surface characteristics into operable process parameters, ensuring that glasses with different roughnesses can obtain uniform coating and avoiding optical defects in the display panel caused by insufficient or excessive pressure. When the glass surface roughness (RaRa) is high, the relationship between squeegee pressure and roughness may no longer be linear. Therefore, the embodiment introduces a quadratic term k4·Ra. 2 This corrects the pressure requirements under high surface roughness to prevent excessive ink penetration into the micro-grooves of the glass surface due to excessive pressure. K4 is measured in Newtons per square micrometer (N / μm). 2 Ra represents the increase in roughness (Ra) per square micrometer. 2 This requires additional doctor blade pressure. Introducing k4·Ra2 can prevent insufficient ink filling or excessive penetration, keeping the formula accurate over a wider Ra range.

[0076] 104. The coated target glass is conveyed to the imprinting station, and the pressure roller is controlled to move downward to obtain the texture depth of the film. The pressure of the pressure roller is adjusted based on the texture depth of the film and the thickness of the glass to imprint the texture on the film onto the target glass, and the UV lamp is turned on to cure the texture on the target glass.

[0077] In this step, the system conveys the target glass to the imprinting station, and the pressure roller moves down to imprint the texture on the film onto the glass.

[0078] Simultaneously, UV lamps are activated for curing, and once curing is complete, the glass continues to be transported.

[0079] Screen printing with UV coating is a printing process that combines screen printing technology with UV (ultraviolet) curing technology. Ink is applied to the substrate through a screen printing stencil (mold). The image areas of the stencil allow ink to pass through, while the non-image areas are blocked. UV curing uses UV ink containing photosensitizers, which undergo a rapid photochemical reaction under ultraviolet light, instantly curing the liquid ink into a film. Compared to traditional screen printing, UV curing is solvent-free and less polluting.

[0080] In this step, the pressure of the pressure roller is adjusted based on the membrane texture depth and glass thickness. This includes: calculating the standard pressure roller pressure according to the formula P1 = k1·D + k2·T + P0, where P1 is the standard pressure roller pressure, K1 is the membrane texture depth influence coefficient (usually related to material hardness), K2 is the glass thickness compensation coefficient (usually related to glass stiffness), D is the membrane texture depth, T is the glass thickness, and P0 is the preset base pressure (an empirical value); and the current pressure roller pressure is collected and adjusted according to the standard pressure roller pressure. In this embodiment, the membrane temperature depth and glass thickness can be collected by sensors, and preset membrane texture depth influence coefficients and glass thickness compensation coefficients can be matched according to different material types.

[0081] Furthermore, it also includes: collecting ambient temperature, and correcting the standard pressure roller pressure based on the collected ambient temperature using the formula P1=k1D+k2T+α(Tenv-25)+P0, where α is the temperature compensation coefficient and Tenv is the ambient temperature. When acquiring membrane texture depth data, the membrane surface is scanned using a laser displacement sensor to obtain texture depth distribution data Di (i=1,2,...,ni), and then the average texture depth is calculated as the membrane texture depth used in this embodiment. In one application scenario, the thickness of the automotive display glass is T = 2mm. Its OLED-like textured film has a texture depth D = 10µm. The ambient temperature is 30℃. Based on the material type, K1 = 0.05MPa / μm, K2 = 0.02MPa / mm, and P0 = 0.1MPa are obtained from the database. Therefore, the target pressure is calculated as 0.05×10 + 0.02×2 + 0.005×(30-25) + 0.1 = 0.5 + 0.04 + 0.025 + 0.1 = 0.665MPa. This embodiment, by introducing dynamic pressure adjustment and further proposing temperature compensation calculations, can significantly improve the imprinting quality and the intelligence level of the equipment.

[0082] In this embodiment, after UV curing, the system transports the target glass to the output station via guide rails, and finally it is conveyed out by rollers. The equipment uses a servo motor and guide rail system to achieve automatic lifting and conveying of the glass, reducing manual operation and improving production efficiency. Based on visual positioning detection and automatic correction, the system ensures that the product position perfectly matches the screen position. Combined with UV nano-transfer technology, this enhances the layering and three-dimensionality of the glass surface while reducing energy consumption. Using UV curing technology reduces organic waste gas emissions compared to traditional screen printing. The equipment supports various printing processes (such as screen printing, UV transfer, etc.) and is suitable for different types of glass materials.

When a threshold is set, the target glass position is corrected to ensure that the target glass is centered in the positioning station; Glass coating module 203: used to convey the target glass to the coating station, monitor the ink viscosity and ink temperature in real time, and adjust the ink viscosity and ink temperature.
