Description

Technical Field

[0001] The invention belongs to the field of glass processing, and relates to a baking technology after glass silk-screen printing, in particular to a baking system applied to glass silk-screen printing. Background Art

[0002] Glass silk screen printing is an important process in glass processing. It forms the required groups or texts by screen printing on the glass surface. The main purpose of baking after silk screen printing is to make the ink dry thoroughly to prevent the ink from blurring, falling off or affecting the printing effect. The baking process can significantly shorten the curing time of ink or slurry and improve production efficiency. Baking can evaporate the moisture on the surface of the glass to prevent bubbles from being generated during the curing process of ink or slurry, thereby improving the quality of glass products. After drying, the compressive strength, wear resistance and seismic resistance of the glass are significantly improved because the surface moisture is completely volatilized, thereby improving the safety and stability of the glass. Baking can effectively prevent deformation and aging of the glass caused by moisture, thereby extending the service life of the glass.

[0003] In the prior art, the process of baking the glass after silk-screen printing is generally to enable the glaze printed on the glass to be firmly fixed on the glass. Usually, the glass products after silk-screen printing need to be baked at high temperature, and the baking temperature often reaches 520-600°C. In addition, during the baking process, the glass may crack due to different glass materials, which not only affects the product qualification rate but also causes risks in the production process. In addition, the supervision of baking is insufficient, resulting in the failure to timely discover safety hazards, which may cause accidents during the baking process of the glass.

[0006] To achieve the above-mentioned object, the first aspect of the present invention provides a baking system applied to glass after screen printing, comprising: a baking test module, and a data acquisition module and a baking safety module connected thereto;

[0009] The baking equipment is tested using the test glass to obtain test data, and the baking evaluation coefficient is calculated based on the test data; based on the baking evaluation coefficient, it is determined whether the baking operation can be started; if yes, the target glass after screen printing is baked; if no, the baking parameters are adjusted and the baking equipment is tested again;

[0010] Baking safety module: It is used to collect real-time safety data of the baking equipment when baking the target glass, and judge whether the baking is abnormal based on the real-time safety data; if so, an abnormal signal is generated to stop baking the target glass; if not, the real-time safety data is continuously detected; the real-time safety data includes temperature data and current data.

[0011] Preferably, determining the baking parameters according to the performance data comprises:

[0012] Retrieve the glass material and ink type from the performance data of the target glass; determine the temperature range for baking the target glass according to the glass material, and determine the standard range for the glass baking temperature according to the ink type; analyze and obtain the intersection of the temperature range and the standard range, and select the middle value of the intersection as the baking temperature;

[0013] Retrieve the glass thickness from the performance data of the target glass and obtain the thickness time library; match the glass thickness and baking temperature with the thickness time library to obtain the corresponding baking time; integrate the baking temperature and baking time into baking parameters.

[0014] It should be noted that if the temperature range does not overlap with the standard range, the middle value of the range with a smaller temperature value is selected as the baking temperature.

[0015] The present invention determines the baking temperature according to the glass material and the ink type, which can avoid the glass from cracking due to too high a baking temperature, and avoids the baking time from being too long due to too low a baking temperature, which is beneficial to improving the baking efficiency; the baking time is determined according to the glass thickness and the baking temperature, which can ensure that the ink on the glass surface is baked dry.

[0026] Retrieve the test data, and mark the number of surface defects, ink color difference, and light transmittance in the test data as QG, YC, and TG respectively;

[0027] The baking evaluation coefficient of the baking equipment is calculated by the formula HPX=α×1 / QG-β×ln(YC+1)+γ×exp(TG); wherein α, β and γ are all proportional coefficients greater than 0.

[0028] The present invention calculates the baking evaluation coefficient according to the test data, evaluates the baking process, and can analyze whether the glass after baking meets the expected standards. When major quality problems occur, the baking parameters can be adjusted in time to avoid a low glass pass rate due to baking.

If yes, analyze the current data in the real-time safety data; if no, determine that the baking is abnormal;

[0035] The current data in the real-time safety data is retrieved to determine whether the current data is less than the current threshold. If yes, it is determined that the baking is normal; if no, it is determined that the baking is abnormal.

[0044] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1 , the first aspect of the present invention provides a baking system applied to glass after silk screen printing, comprising: a baking test module, and a data acquisition module and a baking safety module connected thereto;

[0046] Data acquisition module: used to collect the performance data of the target glass after screen printing; determine the baking parameters according to the performance data; the performance data includes: glass material, ink type and glass thickness;

[0047] Baking test module: used to control the baking equipment according to the baking parameters, detect the real-time temperature in the baking equipment after the set time period, and judge whether the baking equipment can be tested; if yes, obtain the test glass for baking test; if no, continue to detect the real-time temperature of the baking equipment;

[0048] The baking equipment is tested using the test glass to obtain test data, and the baking evaluation coefficient is calculated based on the test data; based on the baking evaluation coefficient, it is determined whether the baking operation can be started; if yes, the target glass after screen printing is baked; if no, the baking parameters are adjusted and the baking equipment is tested again;

[0049] Baking safety module: It is used to collect real-time safety data of the baking equipment when baking the target glass, and judge whether the baking is abnormal based on the real-time safety data; if so, an abnormal signal is generated to stop baking the target glass; if not, the real-time safety data is continuously detected; the real-time safety data includes temperature data and current data.

[0050] See also Figure 2 , collect the performance data of the target glass after silk screen printing; retrieve the glass material and ink type from the performance data of the target glass; determine the temperature range of the target glass baking according to the glass material, and determine the standard range of the glass baking temperature according to the ink type; analyze and obtain the intersection of the temperature range and the standard range, and select the middle value of the intersection as the baking temperature; retrieve the glass thickness from the performance data of the target glass, and obtain the thickness time library; match the glass thickness and baking temperature with the thickness time library to obtain the corresponding baking time; integrate the baking temperature and baking time into baking parameters.

[0051] For example: Assume that there are target glass A and target glass B; analyze the baking parameters of the two glasses respectively:

[0052] Target glass A: The temperature range is 100℃ to 130℃; the standard range is 110℃ to 125℃; the baking temperature is set to 117.5℃. Since the value after the decimal point is difficult to control, the baking temperature is set to 118℃; the glass thickness is 2.5mm, and it takes 10 minutes to bake at a baking temperature of 118℃;

[0053] Target glass B: The temperature range is 120℃ to 160℃; the standard range is 140℃ to 170℃; the baking temperature is set to 150℃; the glass thickness is 4.0mm, and it needs to be baked for 15 minutes at a baking temperature of 150℃.

[0054] The baking equipment is controlled according to the baking parameters, and the real-time temperature in the baking equipment is detected after the set time period; it is determined whether the real-time temperature is consistent with the baking temperature; if yes, the test glass is obtained for baking test; if not, the real-time temperature of the baking equipment is continuously detected.

[0055] For example: suppose that the real-time temperatures of baking equipment A and baking equipment B are tested. At time T1, it is detected that the real-time temperature of baking equipment A is consistent with the baking temperature, then the test glass A is tested; the real-time temperature of baking equipment B is lower than the baking temperature, then the real-time temperature of baking equipment B is continuously tested; at time T2, it is detected that the real-time temperature of baking equipment B is consistent with the baking temperature, then the test glass B is tested.

[0056] See also Figure 3 , retrieve the test glass; set the baking time of the test glass according to the baking parameters, and put the test glass into the baking equipment for baking; after the baking is completed, use a special tool to take out the test glass and cool it to room temperature; test the cooled test glass to obtain test data; wherein the test data includes the number of surface defects, ink color difference and light transmittance.

[0057] For example: suppose that test glass A and test glass B are tested. According to the baking parameters, test glass A is placed in baking equipment A at a baking temperature of 118°C and baked for 10 minutes; test glass B is placed in baking equipment B at a baking temperature of 150°C and baked for 15 minutes; after baking, test glass A and test glass B are taken out for cooling respectively, and the cooled test glass A and test glass B are tested to obtain test data.

[0058] Retrieve the test data, and mark the number of surface defects, ink color difference and transmittance in the test data as QG, YC and TG respectively; calculate the baking evaluation coefficient of the baking equipment by the formula HPX=α×1 / QG-β×ln(YC+1)+γ×exp(TG); wherein α, β and γ are all proportional coefficients greater than 0; determine whether the baking evaluation coefficient is greater than the coefficient threshold; if yes, bake the target glass after silk-screen printing; if not, adjust the baking parameters and retest the baking equipment.

[0059] For example: Assume that the test data of test glass A and test glass B are tested, α=1, β=10, γ=0.5. The specific analysis is as follows:

[0060] Test glass A: number of surface defects QG = 3, ink color difference YC = 0.05, light transmittance TG = 90%; then the baking evaluation coefficient HPX = 1.08; greater than the coefficient threshold 0.9; then the target glass A is baked;

[0061] Test glass B: number of surface defects QG=5, ink color difference YC=0.12, transmittance TG=84%; then the baking evaluation coefficient HPX=0.225; which is less than the coefficient 0.9; then adjust the baking parameters and retest the baking equipment B until the baking evaluation coefficient is greater than the coefficient threshold.

[0062] When baking the target glass, collect the real-time safety data of the baking equipment, retrieve the temperature data in the real-time safety data, and determine whether the difference between the temperature data and the baking temperature is within a preset difference range. If yes, analyze the current data in the real-time safety data; if not, generate an abnormal signal and stop baking the target glass; retrieve the current data in the real-time safety data and determine whether the current data is less than the current threshold. If yes, continue to detect the real-time safety data; if not, generate an abnormal signal and stop baking the target glass.

[0063] For example: suppose that baking equipment A and baking equipment B are tested during the baking process until baking equipment A completes baking, and the difference between the temperature data of baking equipment A and the baking temperature is within the difference range; the current data is less than the current threshold, then there is no abnormality in baking equipment A; the baking process of baking equipment B is tested, and at time T1 it is found that the difference between the temperature data and the baking temperature exceeds the difference range, then the baking of the target glass B is stopped immediately, and the baking equipment B is analyzed and processed for abnormalities.

[0064] Part of the data in the above formula is calculated by removing the dimension and taking its numerical value. The formula is a formula closest to the actual situation obtained by software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained through simulation of a large amount of data.

[0065] Working principle of the present invention: The present invention collects performance data of target glass after silk-screen printing; determines baking parameters according to the performance data; controls baking equipment according to the baking parameters, detects the real-time temperature in the baking equipment after a set time period, and determines whether the baking equipment can be tested; if yes, obtains test glass for baking test; if no, continuously detects the real-time temperature of the baking equipment; uses the test glass to test the baking equipment to obtain test data, and calculates a baking evaluation coefficient according to the test data; determines whether the baking operation can be started based on the baking evaluation coefficient; if yes, bakes the target glass after silk-screen printing; if no, adjusts the baking parameters and retests the baking equipment. When baking the target glass, collects real-time safety data of the baking equipment, and determines whether the baking is abnormal according to the real-time safety data; if yes, generates an abnormal signal, and stops baking the target glass; if no, continuously detects the real-time safety data.

[0066] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
