Description

Technical Field

[0001] The present invention relates to the technical field of glass embossing, and particularly relates to a full-automatic continuous roll coating and embossing control method and device for glass. Background Art

[0002] At present, with the rapid growth in the demand for display panels, architectural decorative glass, and high-end packaging glass, the glass surface transfer printing technology has become one of the core processes for achieving complex textures, high-precision patterns, and OLED-like display effects. However, the existing technologies still have significant defects in aspects such as multi-parameter collaborative control, automation accuracy, and process adaptability, which restrict the further improvement of production efficiency and product quality. The existing embossing technologies have problems such as poor texture uniformity, insufficient continuity, and low efficiency. Traditional transfer printing requires multiple coatings and curing, and the single-piece production cycle is as long as 5 - 10 minutes, making it difficult to meet the requirements of large batch orders. Manual or local embossing is prone to generating bubbles and uneven thickness, especially on glass, which affects optical consistency. Moreover, the existing equipment relies on manual loading and unloading and tension conditions, with a large deviation rate of the coil material and a high probability of knife embossing misalignment, requiring frequent shutdowns for adjustment.

[0067] Embodiment 1

[0068] Please refer to Figure 1 , Figure 1 which is a schematic flow chart of a full-automatic glass continuous roll coating and embossing control method disclosed in an embodiment of the present invention. Among them, the execution subject of the method described in the embodiment of the present invention is an execution subject composed of software or / and hardware. The execution subject can receive relevant information through wired or / and wireless means and can send certain instructions. Of course, it can also have certain processing functions and storage functions. The execution subject can control multiple devices, such as remote physical servers or cloud servers and related software, or can also be a local host or server and related software that performs relevant operations on devices placed somewhere. In some scenarios, multiple storage devices can also be controlled, and the storage devices can be placed in the same place or different places as the devices. As Figure 1 shown, the full-automatic glass continuous roll coating and embossing control method includes the following steps:

[0069] 101. In response to the glass embossing instruction, obtain the glass parameters and embossing parameters, where the glass parameters include the glass thickness, and the embossing parameters include the texture depth of the film material.

[0070] The control device structure of this embodiment is as Figure 2 shown, in combination with Figure 2, which is composed of a total of four workstations. One workstation is the feeding workstation 1, where the coil material, that is, the embossing film material, is placed. One workstation is the pressing workstation 2. After the target glass is transported to the pressing workstation 2 through the transfer rollers, the pattern on the embossing film material is embossed on the target glass at this workstation. One workstation is the curing workstation 3, which is used to photocure the pattern embossed on the target glass. One workstation is the receiving workstation 4, where the embossing film material after embossing is recycled.

[0071] The glass embossing instruction is used to start the system process. This instruction may be manually input or automatically triggered when the system meets the conditions. In this step, intelligent parameter matching can be achieved. For example, different embossing film materials and pressing roller pressures are matched according to different glass sizes. Exemplarily, the pressing roller pressure of vehicle-mounted glass is automatically matched to 0.45 MPa to avoid material waste caused by manual trial and error.

[0072] 102. Collect the edge image of the embossing film material, calculate the center line deviation of the embossing film material, and correct the position of the embossing film material based on the center line deviation.

[0073] Traditionally, there is a lack of deviation correction for the coil material, or manual deviation correction is carried out when the deviation rate is large, resulting in too large a stretching rate of the film material, causing waste of the film material and short service life. In the embodiment, the two side edges of the coil material are detected by CCD vision, and then it is calculated whether the embossing film material has a position deviation.

[0074] Specifically, collect the edge image of the embossing film material, and obtain the sub-pixel coordinates of the two side edges of the embossing film material as (X L , Y L ) and (X R , Y R ); calculate the center line deviation of the embossing film material according to the formula , where Δ center is the center line deviation, and the X ref is the abscissa of the preset reference center line.

[0075] Furthermore, correcting the position of the embossing film material based on the center line deviation includes: calculating the deviation change rate according to the center line deviation, and adjusting the PID parameters in combination with the fuzzy rule table based on the center line deviation and the deviation change rate. The PID parameters are the control coefficients for controlling the movement of the pressing roller in the pressing workstation; calculating the PID control quantity according to the PID parameters, the center line deviation and the deviation change rate; obtaining the movement speed of the embossing film material, calculating the speed compensation quantity, and calculating the sum of the PID control quantity and the speed compensation quantity as the total control quantity; collecting the actual displacement of the embossing film material, and judging whether to correct the center line deviation according to the difference between the total control quantity and the actual displacement. When the difference is greater than the set threshold, correct the position of the embossing film material.

[0076] In this step, the deviation e(k) is set as Δ center , and the deviation change rate Δe(k) = e(k) - e(k - 1). The above PID parameters include K p , K i , and K d . K p = 0.8 + 0.5·|e(k)|, K i = 0.1·(1 - e^(-|e(k)| / 0.1)), K d = 0.05 + 0.02·sign(Δe(k)). And the PID control quantity u(k) = K p ·e(k) + K i ·∑i = 0^k e(i)·Ts + K d ·T s . T s = 0.005s is the control period, and u(k) is the PID control quantity. The PID parameters are the coefficients of the proportional, integral, and derivative control links in the control system, which are used to adjust the system response speed, stability, and accuracy. In the proportional term, K p is used as the proportional coefficient for calculation, indicating that the output is adjusted according to the current error. The larger the error, the stronger the control force. Increasing K p means that the response speed is accelerated but may cause oscillation, while decreasing K p means that the response becomes slower, but the steady-state error may remain. In the integral term, K i is the integral coefficient. When increasing K i , it means that the steady-state error is eliminated faster, but oscillation may be triggered. When decreasing K i , it means that the system is more stable, but the steady-state error may remain. And K d is the differential coefficient of the differential term. When increasing K d , the system damping is enhanced and the response is smoother. When decreasing K d , the system convergence becomes slower. That is, K p determines the immediate response to the current error, K i is responsible for eliminating the long-term deviation, and K d anticipates the change trend to smooth the response. Reasonably adjusting the balance of the three can achieve fast, stable, and accurate control effects. According to the web speed v, the dynamic offset can be predicted. Therefore, in the present invention, in addition to considering the PID parameters to adjust the deviation, the movement speed of the film material is also considered to calculate the speed compensation, U feedforward=0.03·v·sin(2τπt)(τ=0.2s), the total control amount needs to add the two together, and then use the sum as the opening of the pneumatic valve to obtain the actual displacement of the imprinted film material, that is, the offset roller displacement, and calculate the difference between the total control amount and the offset roller displacement. Based on the difference, it is determined whether it exceeds the set threshold and whether the offset roller correction is triggered.

[0077] 103. The target glass is transferred to the pressing station, the pressing roller is controlled to move downward, and the pressure of the pressing roller is adjusted based on the film texture depth and the glass thickness to imprint the texture on the imprinted film onto the target glass.

[0078] Specifically, in this step, the standard roller pressure is calculated according to the formula P1 = k1·D + k2·T + P0, where P1 is the standard roller pressure, K1 is the film material texture depth influence coefficient, K2 is the glass thickness compensation coefficient, D is the film material texture depth, T is the glass thickness, and P0 is the preset base pressure. The current roller pressure is then collected and adjusted based on the standard roller pressure. In this embodiment, sensors can be used to collect film material temperature depth and glass thickness, and preset film material texture depth influence coefficients and glass thickness compensation coefficients can be matched to different material types.

[0079] 104. The pressed target glass is transferred to a curing station, and a UV lamp is started to cure the texture on the target glass.

[0080] In addition, the embodiment may further include the step of conveying the solidified target glass to a receiving station, and controlling the receiving mechanism to recycle the imprinted film material on the target glass. In the present invention, the cleaned target glass is uploaded to the process operation table, and the coiled material is placed in the unloading station 1, and then enters the pressing station 2. The system presses the texture on the coiled material to the surface of the target glass. The target glass then continues to flow and solidify. At this time, the coiled material is also pressed on the target glass. The coiled material can be coated with a release layer on the surface, which can be automatically peeled off after UV curing. Therefore, when it is transported to the receiving station, the film material can be quickly separated from the target glass without residue, and then the film material can be recycled.

[0081] Further, before responding to the glass imprinting instruction, it further includes: clamping the target glass and transporting it to the positioning station, collecting the edge image information of the target glass, calculating the center coordinates of the target glass, defining the centered position of the positioning station as the coordinate origin, calculating the deviation vector between the center coordinates and the coordinate origin, and correcting the position of the target glass when the deviation vector is greater than the set threshold so that the target glass is located at the centered position of the positioning station; transporting the target glass to the coating station, monitoring the ink viscosity and ink temperature in real time, adjusting the ink viscosity and ink temperature, obtaining the surface roughness of the glass, setting the coating blade pressure based on the surface roughness of the glass to perform screen printing UV coating on the target glass, and collecting the current coating ink layer thickness in real time to stop the blade work when the current coating ink layer thickness meets the coating ink layer thickness requirement.

[0082] For the entire process of imprinting the target glass, the washed target glass is transported to the console. First, the target glass is positioned, and after positioning, position correction is performed so that the target glass is at the set centered position to ensure precise operation in subsequent processes. After positioning, screen printing UV coating treatment is performed on the target glass. Further, the ink viscosity and ink temperature are monitored in real time, and the ink viscosity and ink temperature are adjusted, including: collecting the current ink viscosity through a viscosity sensor, collecting the current ink temperature through a temperature sensor, and performing average filtering processing on the collected current ink viscosity and current ink temperature; comparing the viscosity difference between the current ink viscosity and the set ink viscosity threshold, and when the viscosity difference is greater than the set value, calculating the temperature adjustment amount according to the ratio between the viscosity difference and the temperature sensitivity coefficient; adjusting the current ink temperature based on the temperature adjustment amount.
