Description

Technical Field

[0001] The present application relates to the field of intelligent control technology, which is applied to the photovoltaic field, and in particular to a tempering furnace, method and controller for efficient and uniform heating. Background Art

[0002] In the process of tempering float glass, the traditional heating process has many shortcomings, which seriously affect the quality and production efficiency of tempered glass. These shortcomings are mainly reflected in the following aspects:

[0003] 1. Poor matching of the number of films: Traditional tempering furnaces lack a scientific method to accurately calculate the number of films, resulting in a mismatch between the number of films and the heating capacity. For example, if the number of films is too large, the temperature in the furnace will drop, affecting the heating effect; if the number of films is too small, it will cause a waste of heating capacity and increase energy consumption.

[0004] 2. Random placement of glass: The traditional placement method does not have a standardized layout system, and the placement of glass is random, which makes the heat distribution in the furnace chaotic. Local overheating or overcooling occurs frequently, resulting in uneven heating of the glass and unreasonable stress distribution, which affects the strength and stability of tempered glass.

[0005] 3. Extensive control of heating zones: The heating zones are divided into large areas: The heating zones of traditional tempering furnaces are divided into large areas, which cannot be finely adjusted according to the heating requirements of different parts of the glass, and cannot meet the requirements of high-quality tempering. This may cause some parts to overheat, while other parts may not be heated enough.

[0006] 4. Insufficient understanding of the heating characteristics of the central area: The central area of ​​the furnace is the main area where the glass continuously absorbs heat, but the traditional process does not fully understand the heating characteristics of this area and does not fully consider the continuous heat absorption of the glass in this area. As a result, the temperature of the glass in the central area is low, and the temperature difference with the edge area is too large, resulting in optical distortion such as "hot edge" and poor surface flatness.

[0007] 5. Low temperature control accuracy: The temperature control system of traditional tempering furnaces has low accuracy and cannot adjust the temperature of each area in real time and accurately, which easily causes temperature fluctuations. Temperature fluctuations not only affect the stability of the tempering effect, but also increase energy waste and increase production costs.

[0008] Therefore, there is an urgent need for a tempering furnace with efficient and uniform heating to solve at least one of the above problems. Summary of the invention

[0050] 4. Optimization of central area heating characteristics: The controller can identify the heating characteristics of the central area of ​​the furnace and generate a temperature curve that is more suitable for the central area.

[0069] In the process of tempering float glass, the traditional heating process has many shortcomings, which seriously affect the quality and production efficiency of tempered glass. These shortcomings are mainly reflected in the following aspects:

[0070] 1. Poor matching of the number of films: Traditional tempering furnaces lack a scientific method to accurately calculate the number of films, resulting in a mismatch between the number of films and the heating capacity. For example, if the number of films is too large, the temperature in the furnace will drop, affecting the heating effect; if the number of films is too small, it will cause a waste of heating capacity and increase energy consumption.

[0071] 2. Random placement of glass: The traditional placement method does not have a standardized layout system, and the placement of glass is random, which makes the heat distribution in the furnace chaotic. Local overheating or overcooling occurs frequently, resulting in uneven heating of the glass and unreasonable stress distribution, which affects the strength and stability of tempered glass.

[0072] 3. Extensive control of heating zones: The heating zones are divided into large areas: The heating zones of traditional tempering furnaces are divided into large areas, which cannot be finely adjusted according to the heating requirements of different parts of the glass, and cannot meet the requirements of high-quality tempering. This may cause some parts to overheat, while other parts may not be heated enough.

[0073] 4. Insufficient understanding of the heating characteristics of the central area: The central area of ​​the furnace is the main area where the glass continuously absorbs heat, but the traditional process does not fully understand the heating characteristics of this area and does not fully consider the continuous heat absorption of the glass in this area. As a result, the temperature of the glass in the central area is low, and the temperature difference with the edge area is too large, resulting in optical distortion such as "hot edge" and poor surface flatness.

[0074] 5. Low temperature control accuracy: The temperature control system of traditional tempering furnaces has low accuracy and cannot adjust the temperature of each area in real time and accurately, which easily causes temperature fluctuations. Temperature fluctuations not only affect the stability of the tempering effect, but also increase energy waste and increase production costs.

[0075] Therefore, there is an urgent need for a tempering furnace with efficient and uniform heating to solve at least one of the above problems.

[0076] To solve the above problems, please refer to Figure 1 and Figure 2 The present application provides a tempering furnace with high efficiency and uniform heating, which comprises: a workbench 1; a conveying roller 2, which is arranged on the workbench 1 (the conveying roller 2 can be Figure 1 The servo motor 6 in the furnace drives the glass sheet to be tempered to rotate); a mechanical arm 8, the mechanical arm 8 is used to place the glass sheet to be tempered on the conveying roller 2; a furnace body 5, the furnace body 5 is arranged on the workbench 1 via the conveying roller 2 (the furnace body 5 may also include Figure 1 a display screen 3 and an operating table 4 in the furnace, for allowing the user to perform relevant operations on the tempering furnace); a collection module, for collecting glass sheet parameters of the glass sheet; a controller, the controller is used to generate the number of tempered glass sheets according to the heating parameters, tempering time and glass sheet parameters of the furnace body 5, divide the furnace body 5 into a plurality of heating zones 13 according to the number of tempered glass sheets, and generate a tempering temperature curve corresponding to each heating zone 13 according to the zone position, heating parameters, tempering time and glass sheet parameters corresponding to each heating zone 13; control the mechanical arm 8 to place the corresponding glass sheet according to the zone position, and control the conveying roller 2 to move the plurality of glass sheets into the furnace body 5, and complete the tempering of the glass in each heating zone 13 according to each tempering temperature curve.

[0077] Specifically, the workbench 1 is made of high-strength, high-temperature-resistant metal materials, such as stainless steel or heat-resistant alloy steel, to ensure long-term stable use in a high-temperature environment. It is designed as a modular structure for easy disassembly and maintenance. The surface of the workbench 1 is flat to ensure the smooth operation of the conveyor roller 2 and the robot arm 8.

[0078] The conveyor roller 2 is made of high-temperature alloy steel, and its surface is specially treated to reduce scratches and friction on the glass during the conveying process. It is driven by a variable frequency motor, and the conveying speed can be adjusted according to the instructions of the controller to ensure the uniformity and stability of the glass during the heating process. A temperature sensor is installed on the conveyor roller 2 to monitor the temperature of the conveyor roller 2 in real time to prevent high temperature from causing adverse effects on the glass.

[0079] The robot arm 8 uses a high-precision servo motor and sensor to ensure that the positioning error of the robot arm 8 during the placement process is less than ±0.5mm. The robot arm 8 has multi-axis motion capabilities and can adapt to glass pieces of different sizes and shapes, ensuring that each glass piece can be accurately placed at the predetermined position. The robot arm 8 is connected to the controller through wireless communication, and receives and executes the controller's instructions in real time, improving production efficiency and flexibility.

[0080] The furnace body 5 uses multiple layers of thermal insulation materials, such as ceramic fiber and aluminum silicate fiber, to reduce heat loss and improve energy efficiency. The interior of the furnace body 5 is divided into multiple independent heating zones 13, each of which is equipped with an independent heating element and temperature controller. For example, the furnace body 5 can be divided into 6 zones, each of which is responsible for heating an area of ​​1600mm x 1000mm. The controller can dynamically adjust the number and position of the heating zones 13 according to the number and parameters of the glass sheets to ensure that each glass sheet can be tempered under the best heating conditions.

[0081] The acquisition module includes laser distance sensors, infrared temperature sensors, weight sensors, etc., which comprehensively collect the physical parameters of the glass sheet. The acquisition module transmits the collected data to the controller in real time. The controller analyzes and processes the data through algorithms to generate accurate tempering parameters. The acquisition module has a self-calibration function to ensure the accuracy of the data. For example, the laser distance sensor can be regularly calibrated to zero point, and the infrared temperature sensor can adapt to changes in ambient temperature.

[0082] The controller uses advanced optimization algorithms, such as genetic algorithms, neural networks, and fuzzy control, to generate the optimal tempering temperature curve according to the heating parameters of the furnace body 5, the tempering time, and the glass sheet parameters. The controller can dynamically adjust the heating power and time of each partition to ensure that the temperature distribution of each partition meets the tempering requirements. The controller has fault detection and self-diagnosis functions, which can monitor the operating status of the furnace body 5 in real time, detect and handle faults in time, reduce downtime, and improve production continuity. The controller can store historical production data, optimize production parameters through big data analysis, and improve tempering quality and production efficiency.

[0083] For example, suppose there is a batch of glass sheets of different thicknesses, sizes and materials that need to be tempered, including 50 pieces of 5mm thick float glass, 30 pieces of 8mm thick tempered glass, and 20 pieces of 10mm thick laminated glass. The acquisition module uses a laser range finder sensor to measure the thickness and size of each piece of glass, an infrared temperature sensor to measure the initial temperature of the glass, and a weight sensor to measure the weight of the glass. The collected data includes: 5mm float glass (1800mm x 1000mm), 8mm tempered glass (2000mm x1500mm), 10mm laminated glass (2200mm x 1200mm). Generate the number of tempered glass sheets: The controller calculates the number that can be placed in each batch based on the heating parameters and tempering time of the furnace body 5. Assuming that the furnace body 5 can process 10 pieces of glass at a time, the number of pieces generated by the controller is:

[0084] First batch: 10 pieces of 5mm float glass.

[0085] The second batch: 6 pieces of 8mm tempered glass and 4 pieces of 10mm laminated glass.

[0086] The third batch: 6 pieces of 8mm tempered glass and 4 pieces of 10mm laminated glass.

[0087] The fourth batch: 6 pieces of 8mm tempered glass and 4 pieces of 10mm laminated glass.

[0088] The controller divides the interior of the furnace body 5 into six heating zones 13 (with Figure 2The number of divisions is the same as 16, and the application does not limit the number of divisions. 6 is only a specific embodiment). Each partition independently controls the temperature and heating time. In the first batch, each partition processes 2 pieces of 5mm float glass. In the second batch, each partition processes 1 piece of 8mm tempered glass and 1 piece of 10mm laminated glass. The controller generates a tempering temperature curve for each partition according to the partition position, heating parameters, tempering time and glass sheet parameters of each partition. For example, the temperature curve of the central partition is designed to be continuously heated, and the maximum temperature is set to 650°C to compensate for the heat absorption effect of the central area. The temperature curve of the edge partition is designed to heat up slowly, and the maximum temperature is set to 620°C to avoid local overheating. According to the instructions of the controller, the robot arm 8 accurately places the glass sheet on the conveying roller 2, and each partition position has a corresponding glass sheet. The conveying roller 2 smoothly transports the glass sheet to the furnace body 5, and the controller adjusts the temperature of each partition in real time through the temperature control system to ensure uniform heating. For example, the controller instructs the robot arm 8 to place 5 mm float glass in the first and second partitions, 8 mm tempered glass in the third and fourth partitions, and 10 mm laminated glass in the fifth and sixth partitions.

[0089] By accurately calculating the number of sheets to be placed, it is ensured that the number of sheets placed each time matches the heating capacity of the furnace body 5, thereby improving the heating efficiency and reducing energy waste. For example, the first batch processes 10 sheets of 5mm float glass, and the second batch processes 10 sheets of glass of different thicknesses, thereby avoiding the problem of too many or too few sheets. The high-precision placement of the robotic arm 8 and the partition management of the controller make the placement position more standardized and the heat distribution in the furnace more uniform. For example, 5mm float glass is placed in the central partition, and 8mm tempered glass and 10mm laminated glass are placed in the edge partition, thereby reducing the phenomenon of local overheating or overcooling and improving the quality of tempered glass. Multiple independent heating partitions 13 can accurately heat the glass in different parts to meet the requirements of high-quality tempering. For example, the temperature of the central partition is set to 650°C, and the temperature of the edge partition is set to 620°C, thereby ensuring the uniformity of heating of various parts of the glass. By specifically optimizing the heating curve of the central area, the heat absorption effect of the central area is compensated, the problems of optical distortion such as "hot edge" and poor surface flatness are reduced, and the visual and physical properties of the product are improved. For example, the central partition adopts a continuous heating method to ensure that the temperature of the central area is stable at 650°C, which improves the strength and stability of the glass. The controller adjusts the temperature of each partition in real time to ensure small temperature fluctuations and stable tempering effect, further improving production efficiency and product quality. For example, the controller adjusts the heating power according to real-time temperature data to keep the temperature fluctuating within the range of ±5°C, which greatly improves the stability of the tempering effect. The controller can monitor the operating status of the furnace body 5 in real time, detect and handle faults in time, reduce downtime, and improve production continuity. For example, if the temperature sensor of a partition fails, the controller will immediately record and alarm, and the operator can make repairs in time. The controller can store historical production data, optimize production parameters through big data analysis, and improve tempering quality and production efficiency. For example, the controller optimizes the number and position of heating partitions 13 based on historical data, reduces tempering time, and increases output.

[0090] Through the above technical content and examples, it can be seen that this high-efficiency and uniformly heated tempering furnace not only solves many deficiencies in traditional processes, but also achieves high-quality and high-efficiency production in the tempering process through intelligent and automated technologies. This tempering furnace has significant advantages in practical applications and can significantly enhance the competitiveness of enterprises.

[0091] In some embodiments, the furnace body 5 includes an inlet and an outlet, the robot arm 8 places the glass sheet at the inlet of the furnace body 5, and the conveying roller 2 conveys the glass sheet into the furnace body 5 and conveys the glass sheet out through the outlet after tempering is completed.

[0092] The furnace body 5 includes an entrance and an exit, and these two areas are designed to facilitate the entry and exit of glass sheets. The entrance and exit areas are usually equipped with insulation doors to reduce heat loss. The insulation door can be automatically opened and closed when the glass sheets enter and exit to ensure that the temperature inside the furnace body 5 is stable. The insulation door is made of high-temperature resistant materials, which can respond quickly and maintain sealing. The robot arm 8 (which can be a multi-degree-of-freedom robot arm 8) is usually installed near the entrance of the furnace body 5 and is responsible for accurately placing the glass sheets from the workbench 1 or the storage area on the conveyor roller 2. When placing the glass sheets, the robot arm 8 will place the glass sheets at the specified position of the conveyor roller 2 according to the instructions of the controller. The placement action needs to be gentle and accurate to avoid damage to the glass sheets. The design of the conveyor roller 2 at the entrance section needs to consider the initial introduction of the glass sheets to ensure that the glass sheets can transition smoothly when entering the furnace body 5. The design of the conveyor roller 2 at the exit section needs to consider the cooling and stable transmission of the glass sheets after the tempering is completed. A cooling device, such as forced air cooling or water cooling, is usually set at the exit section to quickly reduce the temperature of the glass sheets. The conveying speed of the conveyor roller 2 can be dynamically adjusted by the controller according to the parameters of the glass sheet and the tempering time to ensure that the residence time of each glass sheet in the furnace body 5 meets the tempering requirements. The controller will generate a sheet placement instruction based on the heating parameters of the furnace body 5, the tempering time and the glass sheet parameters, and the robot arm 8 will place the glass sheet at the specified position of the conveyor roller 2 according to these instructions. The controller will generate a conveying instruction to adjust the speed and direction of the conveyor roller 2 to ensure that the glass sheet enters the furnace body 5 smoothly and moves inside the furnace body 5. The controller will monitor the temperature of each partition of the furnace body 5 in real time, and dynamically adjust it according to the tempering temperature curve to ensure uniform and stable heating. When the tempering of the glass sheet is completed, the controller will generate a sheet discharge instruction to control the conveyor roller 2 to convey the glass sheet out of the furnace body 5 from the outlet. At the same time, the cooling device of the outlet section will be started to ensure that the glass sheet is gradually cooled to a safe temperature during the conveying process.

[0093] The automatic sheet placement of the robot arm 8 and the smooth transmission of the conveyor roller 2 reduce the time and error of manual operation and improve production efficiency. The controller adjusts the transmission speed according to the parameters of the glass sheet to ensure that each piece of glass stays in the furnace body 5 for the optimal time, reducing ineffective waiting and heating time. The insulation door at the entrance reduces the heat loss inside the furnace body 5 and ensures the stability of the temperature inside the furnace. The cooling device at the exit can quickly reduce the temperature of the tempered glass sheet to avoid further influence of high temperature on the glass sheet, while also improving the cooling efficiency and reducing the cooling time. The high-precision sheet placement of the robot arm 8 ensures the accurate position of the glass sheet in the furnace body 5, avoids local overheating or overcooling, and improves the strength and stability of the tempered glass. The real-time temperature monitoring and dynamic adjustment of the controller make the temperature distribution inside the furnace body 5 more uniform, reduce temperature fluctuations, and ensure the high quality of the tempering effect. The insulation door design at the entrance and exit effectively reduces heat loss and reduces energy consumption. The controller optimizes the temperature of each heating zone 13 according to the specific parameters of the glass sheet to avoid overheating and energy waste.

[0094] Automated glass placement and conveying reduce the number of times operators directly contact high-temperature equipment, improving work safety. The cooling device at the exit ensures that the glass sheets are quickly cooled to a safe temperature after being conveyed out of the furnace body 5, avoiding potential dangers to operators and equipment caused by high-temperature glass sheets. The controller can record data such as the placement time, conveying speed, heating temperature and tempering time of each batch of glass sheets, which is convenient for subsequent quality traceability and production optimization. The controller can monitor the operating status of the robot arm 8, conveying roller 2 and furnace body 5 in real time, detect and handle faults in a timely manner, and ensure the continuity and stability of the production process.

[0095] Exemplarily, the conveying roller 2 conveys the glass sheet into the entrance of the furnace body 5 at a predetermined speed according to the conveying instruction of the controller. The design of the conveying roller 2 in the entrance section ensures the smooth transition of the glass sheet and avoids scratches and wear of the glass sheet when entering the furnace body 5. For example, the interior of the furnace body 5 is divided into 6 independent heating zones 13, each of which is responsible for heating 1-2 of the 10 pieces of glass. The controller generates a tempering temperature curve for each zone according to the zone position, heating parameters, tempering time and glass sheet parameters of each zone. For example, the temperature of the central zone is set to 650°C, and the temperature of the edge zone is set to 620°C to ensure that all parts of the glass are heated evenly. When the glass sheet is tempered in the furnace body 5, the conveying roller 2 conveys the glass sheet out of the furnace body 5 from the outlet according to the sheet discharge instruction of the controller. The cooling device of the outlet section is started to quickly reduce the temperature of the glass sheet to a safe temperature to ensure that the glass sheet will not burn the operator or damage the equipment after being conveyed out of the furnace body 5. The controller records the data such as the sheet placement time, conveying speed, heating temperature and tempering time of each batch of glass sheets. Through big data analysis, the parameters of subsequent production batches are optimized to improve production efficiency and tempering quality.

[0096] In summary, by setting the inlet and outlet on the furnace body 5, combined with the automatic sheet placement of the robot arm 8 and the smooth transmission of the conveyor roller 2, the high efficiency and uniformity of tempered glass production are achieved. This design not only improves production efficiency and reduces energy waste, but also ensures the quality and safety of tempered glass. Through the intelligent management and data recording of the controller, the production process is further optimized and the production management level of the enterprise is improved.

[0097] Exemplarily, a cleaning cabin 11 and a drain pipe 10, wherein the cleaning cabin 11 is arranged on the conveying roller 2 and after the outlet of the furnace body 5, and the drain pipe 10 is arranged below the cleaning cabin 11; after the conveying roller 2 conveys the tempered glass sheet to the cleaning cabin 11, the cleaning cabin 11 discharges the dust and stains on the glass sheet through the drain pipe 10.

[0098] The cleaning cabin 11 is arranged on the conveying roller 2 and is located after the exit of the furnace body 5, so as to ensure that the tempered glass sheet enters the cleaning cabin 11 immediately after leaving the furnace body 5. The cleaning cabin 11 generally includes a closed chamber, and a cleaning device such as a spray head, a blowing device and a scrubbing device is installed inside to remove dust and stains on the surface of the glass sheet. The operation of the cleaning cabin 11 can be automated or semi-automated, including the steps of opening the cabin door, conveying the glass sheet into the cabin, starting the cleaning device, conveying the glass sheet out of the cabin, etc. The drain pipe 10 is arranged below the cleaning cabin 11 to collect and discharge the wastewater and dirt generated during the cleaning process. The drain pipe 10 should have a sufficient diameter to ensure smooth drainage and avoid blockage. The drain pipe 10 can also be connected to the factory's wastewater treatment system to ensure compliance with environmental protection standards. The drain pipe 10 is generally made of corrosion-resistant materials such as stainless steel or plastic to adapt to the corrosiveness of detergents and wastewater.

[0099] The tempered glass sheet is transferred from the outlet of the furnace body 5 to the cleaning cabin 11 via the transfer roller 2. The cleaning device in the cleaning cabin 11 is activated to perform multiple steps of cleaning: a high-pressure spray head is used to spray a cleaning agent to remove dust and stains on the surface of the glass sheet. A high-pressure blower is used to blow away the cleaning agent and remaining stains, and the glass sheet is preliminarily dried. A soft scrubbing device, such as a brush or a rag, is used to further clean and dry the surface of the glass sheet. Wastewater and dirt generated during the cleaning process are discharged through the drain pipe 10 at the bottom of the cleaning cabin 11 and enter the factory's wastewater treatment system.

[0100] Through the multi-step cleaning of the cleaning cabin 11, it is ensured that the surface of the tempered glass sheet is free of dust and stains, and the transparency and aesthetics of the glass sheet are improved. The soft scrubbing device in the cleaning cabin 11 can effectively prevent scratches on the surface of the glass sheet during the cleaning process and protect the integrity of the glass sheet. The design of the cleaning cabin 11 and the drain pipe 10 realizes automatic cleaning, reduces manual intervention, and improves the continuity and efficiency of the production process. The conveying roller 2 quickly conveys the glass sheet from the outlet of the furnace body 5 to the cleaning cabin 11 to ensure seamless connection between the cleaning process and subsequent processes. The tempered glass sheet is cleaned immediately after leaving the furnace body 5, which reduces the chance of dust and stains adhering to the glass surface during the cooling process and reduces the defective rate. A detection device, such as a camera or an infrared sensor, can be installed in the cleaning cabin 11 to monitor the cleaning effect of the glass sheet in real time and feed back the data to the controller. If an uncleaned glass sheet is detected, the controller can instruct it to be re-cleaned or marked as defective. The wastewater generated during the cleaning process is discharged through the drain pipe 10 and enters the factory's wastewater treatment system to ensure compliance with environmental protection standards and avoid environmental pollution. The closed design of the cleaning cabin 11 reduces the spread of dust and stains in the factory and keeps the production environment clean. The soft scrubbing device and high-pressure blowing device in the cleaning cabin 11 reduce the wear on the conveyor roller 2 and the furnace body 5 and extend the service life of the equipment. The sewage pipe 10 is made of corrosion-resistant material to reduce the corrosion of the wastewater to the pipe and ensure the long-term stable operation of the equipment.

[0101] Assume that after the glass sheet is tempered in the furnace body 5, the conveyor roller 2 conveys the glass sheet out of the furnace body 5 from the outlet. The conveyor roller 2 conveys the tempered glass sheet to the entrance position of the cleaning cabin 11, ready for cleaning. After the glass sheet enters the cleaning cabin 11, it is first sprayed with a detergent through a spray head. The detergent can be water or a special cleaning solution to ensure that the dust and stains on the surface of the glass sheet are effectively removed. After the detergent is sprayed, the high-pressure blowing device is started to blow away the detergent and remaining stains, and preliminarily dry the glass sheet. Finally, a soft scrubbing device (such as a brush or a rag) further cleans and thoroughly dries the surface of the glass sheet. The wastewater and dirt generated in the cleaning cabin 11 are discharged through the drain pipe 10 at the bottom and enter the factory's wastewater treatment system. The design of the drain pipe 10 ensures the smooth discharge of wastewater and avoids blockage and secondary pollution. A camera or infrared sensor is installed in the cleaning cabin 11 to monitor the cleaning effect of the glass sheet in real time. If a piece of glass that is not cleaned properly is detected, the controller will instruct it to be re-cleaned or marked as defective, ensuring that each piece of glass meets high quality standards.

[0102] By arranging the cleaning cabin 11 and the drain pipe 10 on the conveying roller 2, the tempered glass sheets can be cleaned automatically and efficiently. This design not only improves the quality and production efficiency of tempered glass, but also reduces the defective rate and environmental pollution, and prolongs the service life of the equipment. Through the intelligent management and real-time detection of the controller, the stability and reliability of the production process are further ensured. This technology has significant advantages in practical applications and can significantly improve the production level and market competitiveness of enterprises.

[0103] In some embodiments, it also includes: an L-shaped column 7, one end of the L-shaped column 7 is connected to the workbench 1, and the other end of the L-shaped column 7 is connected to the robotic arm 8.

[0104] The L-shaped column 7 is a support structure designed in an L shape, one end of which is connected to the workbench 1 and the other end is connected to the mechanical arm 8. The L-shaped column 7 is usually made of high-strength, high-temperature resistant metal materials, such as stainless steel or high-strength alloy steel, to ensure long-term stable use in a high-temperature environment. The L-shaped column 7 is fixed to the workbench 1 by fasteners (such as bolts and nuts), and the mechanical arm 8 is fixed to the other end of the L-shaped column 7 in a similar manner. The L-shaped column 7 can be designed to be adjustable, and the height and angle of the mechanical arm 8 can be adjusted by an adjustment device (such as a hydraulic or electric adjustment mechanism) to adapt to glass pieces of different sizes and shapes. The mechanical arm 8 is installed on the L-shaped column 7, and the placement position of the glass piece on the conveying roller 2 can be more accurately located through the support of the L-shaped column 7. The support of the L-shaped column 7 makes the mechanical arm 8 more stable when performing the sheet placement operation, reducing the error caused by vibration or instability. The setting of the L-shaped column 7 can expand the working range of the mechanical arm 8, so that the mechanical arm 8 can cover a larger working area and adapt to glass pieces of different sizes. The workbench 1 is connected to one end of the L-shaped column 7 by a fastener to ensure the stability and strength of the connection. The surface of the workbench 1 is flat to ensure the stability of the glass sheet during placement and transportation and reduce scratches and friction.

[0105] The L-shaped column 7 provides a stable support for the robot arm 8, reduces the vibration and swing of the robot arm 8 during operation, and improves the positioning accuracy of the glass sheet. With the support of the L-shaped column 7, the robot arm 8 can more accurately place the glass sheet at the specified position of the conveyor roller 2, ensuring that each glass sheet can be tempered under the optimal heating conditions. The stable design of the L-shaped column 7 makes the robot arm 8 more stable during the glass sheet placement process, reduces the positioning error caused by vibration, and improves the production quality. The stable robot arm 8 can reduce the downtime caused by inaccurate operation and improve the continuity and efficiency of the production process. The design of the L-shaped column 7 can expand the working range of the robot arm 8, allowing the robot arm 8 to cover a larger working area and adapt to glass sheets of different sizes and shapes. The controller controls the glass sheet by Figure 1The control motor 9 in the L-shaped column adjusts the height and angle of the L-shaped column 7, and the robot arm 8 can operate more flexibly to meet different production needs. With the support of the L-shaped column 7, the layout of the workbench 1 and the furnace body 5 can be better optimized, making the production process more compact and efficient. The adjustable design of the L-shaped column 7 makes the installation and maintenance of the equipment more convenient, and the position and angle of the robot arm 8 can be adjusted according to actual needs. Modular structure: The connection method of the L-shaped column 7 and the robot arm 8 adopts a modular design, which is easy to disassemble and maintain, reducing maintenance time and cost.

[0106] Through the above technical content and examples, it can be seen that the introduction of L-shaped column 7 in the design of the tempering furnace not only improves the positioning accuracy and stability of the mechanical arm 8, but also expands the working range of the mechanical arm 8, reduces the floor space of the equipment, and improves the convenience of installation and maintenance. These improvements make the tempering furnace more efficient, reliable and flexible in actual application, and can significantly improve the production level and competitiveness of the enterprise.

[0107] In some embodiments, the heating parameters include at least heating power and heating efficiency; the glass sheet parameters include at least glass size and glass thickness; the controller determines the tempering time according to the glass thickness and preset tempering requirements, and generates the number of tempered glass sheets according to the tempering time, heating power, glass size and heating efficiency.

[0108] Heating power refers to the energy provided by the furnace 5 heating system per unit time, usually in kilowatts (kW). Heating efficiency refers to the efficiency of the furnace 5 heating system in converting electrical energy into thermal energy, usually expressed as a percentage. Glass size is the length and width of the glass sheet, usually in millimeters (mm). Glass thickness is the thickness of the glass sheet, usually in millimeters (mm).

[0109] The controller calculates the tempering time of each glass sheet according to the thickness of the glass sheet and the preset tempering requirements. The tempering time refers to the total time for the glass sheet to be heated and cooled in the furnace body 5, and the unit is usually seconds (s) or minutes (min). The controller generates the number of tempered glass sheets in each batch according to the tempering time, heating power, glass size and heating efficiency. This involves the accurate calculation of the heating capacity of the furnace body 5 and the transmission capacity of the conveyor roller 2 to ensure the efficiency and stability of the production process. The size of the glass sheet is measured by a laser ranging sensor, and the thickness of the glass sheet is measured by an infrared thickness sensor to ensure the accuracy and reliability of the data. The collected glass sheet parameters are transmitted to the controller by wireless or wired means for further processing. The heating power is set according to the design of the furnace body 5 and the capacity of the heating system. For example, the heating power of the furnace body 5 can be set to 100kW.

[0110] Through experiments and data analysis, the heating efficiency of the furnace body 5 is determined. For example, the heating efficiency of the furnace body 5 can be 90%.

[0111] The algorithm running inside the controller will calculate the tempering time for each piece of glass based on the thickness of the glass and the tempering requirements. The algorithm usually includes calculations based on physical models, taking into account the thermal conductivity characteristics, temperature distribution and cooling rate of the glass. The preset tempering requirements include the target tempering temperature and the performance indicators after tempering (such as strength, heat resistance, etc.).

[0112] The controller calculates the number of glass sheets that can be processed in each batch according to the heating capacity of the furnace body 5 and the transmission capacity of the conveyor roller 2. The heating capacity refers to the area of ​​glass sheets that can be heated by the furnace body 5 per unit time, and the transmission capacity refers to the number of glass sheets that can be transmitted by the conveyor roller 2 per unit time. The controller generates a sheet placement instruction based on the calculation results to ensure that the number of glass sheets and the placement time of each batch meet the heating capacity of the furnace body 5 and the transmission capacity of the conveyor roller 2, thereby achieving efficient production.

[0113] The controller accurately calculates the tempering time according to the thickness of the glass sheet and the preset tempering requirements to ensure that each glass sheet is tempered under the best conditions. Considering the heating power and heating efficiency, the controller can optimize the temperature distribution inside the furnace body 5 to ensure uniform heating of the glass sheet and avoid local overheating or overcooling. According to the heating capacity of the furnace body 5 and the transmission capacity of the conveyor roller 2, the controller generates the number of tempered glass sheets in each batch, realizes batch processing, and improves production efficiency. The controller can dynamically adjust the heating parameters and transmission parameters according to the actual production situation to ensure the continuity and stability of the production process. By accurately controlling the heating time and heating power, overheating is avoided and energy waste is reduced. The number of tempered glass sheets in each batch generated by the controller meets the heating capacity of the furnace body 5 and the transmission capacity of the conveyor roller 2, avoiding ineffective operation and waiting time of the equipment.

[0114] Assume that there is a batch of glass sheets of different thicknesses and sizes that need to be tempered, including 50 pieces of 5mm thick float glass, 30 pieces of 8mm thick tempered glass, and 20 pieces of 10mm thick laminated glass. The acquisition module uses a laser range sensor to measure the size of each piece of glass, and an infrared thickness sensor to measure the thickness of each piece of glass. The collected data includes: 5mm float glass (1800mm x1000mm), 8mm tempered glass (2000mm x 1500mm), 10mm laminated glass (2200mm x 1200mm). The controller calculates the corresponding tempering time according to the thickness of each glass and the preset tempering requirements. For example, the tempering time for 5mm float glass is 8 minutes, the tempering time for 8mm tempered glass is 12 minutes, and the tempering time for 10mm laminated glass is 15 minutes. Generate the number of tempered glass sheets in each batch: The controller generates the number of tempered glass sheets in each batch according to the heating capacity of the furnace body 5 and the transmission capacity of the conveyor roller 2. For example, the heating capacity of the furnace body 5 is 100kW, and the transmission capacity of the conveyor roller 2 is 10 sheets of glass per minute. Assuming that the total number of each type of glass sheets is 50 sheets, 30 sheets, and 20 sheets, respectively, the controller calculates the number of tempered glass sheets in each batch as follows: 5mm float glass: 10 sheets per batch, 5 batches are required. 8mm tempered glass: 5 sheets per batch, 6 batches are required. 10mm laminated glass: 4 sheets per batch, 5 batches are required. The controller generates a sheet placement instruction, and the robot arm 8 accurately places the glass sheets of each batch at the specified position of the conveyor roller 2. For example, the first batch is 10 sheets of 5mm float glass, and the robot arm 8 places these 10 glass sheets on the conveyor roller 2.

[0115] At the same time, the expression for the number of tempered glass sheets can include:

[0116] ;

[0117] is the number of tempered glass sheets, is the heating power, is the heating efficiency, is the tempering time, They are respectively the length corresponding to the glass size, the width corresponding to the glass size, and the glass thickness.

[0118] By introducing the controller to accurately calculate the glass sheet parameters and heating parameters, the optimization of tempering time and the reasonable generation of the number of tempered glass sheets in each batch are achieved. This design not only improves the quality of tempered glass, but also improves production efficiency, reduces energy waste and defective rate. Through real-time monitoring and data recording, the stability and reliability of the production process are further ensured, and the utilization rate of equipment is improved. These improvements make the tempering furnace more intelligent and efficient in practical applications, which can significantly improve the production level and market competitiveness of enterprises.

[0119] Exemplarily, the controller further obtains the glass material information, determines the specific heat capacity of the glass and the unit heat absorption of the glass per unit time and per unit area according to the glass material information, so as to generate an influence coefficient according to the glass material information and the unit heat absorption; the controller generates the number of tempered glass sheets according to the tempering time, glass thickness, influence coefficient, heating power, glass size and heating efficiency; the expression for the number of tempered glass sheets includes:

[0120] ;

[0121] is the number of tempered glass sheets, is the heating power, is the heating efficiency, is the tempering time, They are respectively the length corresponding to the glass size, the width corresponding to the glass size, the glass thickness and the influence coefficient.

[0122] By obtaining the glass material information, the controller can more accurately calculate the specific heat capacity and unit heat absorption of the glass during the tempering process, and then generate an accurate influence coefficient. The introduction of the influence coefficient allows the controller to adjust the heating time and heating power according to the actual heat absorption capacity of the glass, ensuring that each piece of glass is tempered under the best conditions and improving the tempering quality. The controller generates the number of tempered glass sheets in each batch according to the tempering time, glass thickness, influence coefficient, heating power, glass size and heating efficiency, realizing batch processing and improving production efficiency. The controller can dynamically adjust the number of glass sheets in each batch according to the actual production situation to ensure the continuity and stability of the production process. Through the introduction of the influence coefficient, the controller can more accurately control the heating process and avoid energy waste caused by overheating or insufficient heating. The number of tempered glass sheets in each batch meets the heating capacity of the furnace body 5 and the transmission capacity of the conveyor roller 2, avoiding the ineffective operation and waiting time of the equipment and further improving the energy utilization rate. The controller can monitor the temperature change of the furnace body 5 and the tempering state of the glass sheets in real time, adjust the heating parameters in time, and reduce the defective rate caused by improper parameter setting. The controller records the tempering time and parameters of each batch of glass sheets, which is convenient for subsequent quality traceability and analysis, and helps to continuously improve the production process. By accurately calculating the number of tempered glass sheets in each batch, the controller can maximize the heating capacity of the furnace body 5 and the transmission capacity of the conveyor roller 2, thereby improving the utilization rate of the equipment. The controller can flexibly adjust the production plan according to the parameters and tempering requirements of different glass sheets, adapt to the production needs of multiple varieties and small batches, and improve the flexibility of the equipment.

[0123] Suppose there is a batch of glass sheets of different materials and sizes that need to be tempered, including 50 pieces of 5mm thick ordinary float glass, 30 pieces of 8mm thick borosilicate glass, and 20 pieces of 10mm thick laminated glass.

[0124] The acquisition module uses a laser distance sensor to measure the size of each piece of glass, an infrared thickness sensor to measure the thickness of each piece of glass, and a spectrum analyzer to identify the material of the glass. The collected data includes: 5mm ordinary float glass (1800mm x1000mm). 8mm borosilicate glass (2000mm x 1500mm). 10mm laminated glass (2200mm x 1200mm).

[0125] Generation influence coefficient: Ordinary float glass: specific heat capacity is 0.84 J / (g·°C), unit heat absorption is 0.5 J / (cm²·s). Borosilicate glass: specific heat capacity is 0.77 J / (g·°C), unit heat absorption is 0.6 J / (cm²·s). Laminated glass: specific heat capacity is 0.75 J / (g·°C), unit heat absorption is 0.7 J / (cm²·s)

[0126] Calculate the influence coefficient:

[0127] Ordinary float glass: k=0.84×0.5=0.42.

[0128] Borosilicate glass: k = 0.7 × 0.6 = 0.462

[0129] k=0.77×0.6=0.462.

[0130] Laminated glass: k=0.75×0.7=0.525.

[0131] Generate tempering time: According to the preset tempering requirements, the controller calculates the tempering time for each piece of glass. For example, the tempering time for 5mm ordinary float glass is 8 minutes, the tempering time for 8mm borosilicate glass is 12 minutes, and the tempering time for 10mm laminated glass is 15 minutes.

[0132] The controller generates a sheet placement instruction, and the robot arm 8 accurately places each batch of glass sheets on the specified position of the conveying roller 2. For example, the first batch is 3 sheets of 5mm ordinary float glass, and the robot arm 8 places these 3 glass sheets on the conveying roller 2.

[0133] By introducing a controller to obtain information about glass material, the specific heat capacity and unit heat absorption are calculated, and then the influence coefficient is generated. The controller uses these parameters, combined with tempering time, glass thickness, heating power, glass size and heating efficiency, to generate the number of tempered glass sheets in each batch. This design not only improves the quality and production efficiency of tempered glass, but also reduces energy waste and defective rate, improves equipment utilization and the stability of the production process. Through real-time monitoring and data recording, the reliability of the production process is further ensured, which can significantly improve the production level and market competitiveness of the enterprise.

[0134] In some embodiments, the controller generates a plurality of heating partition 13 marks according to the number of tempered glass sheets and the sizes of the glass sheets, so as to control the robot arm 8 to place the plurality of glass sheets according to the heating partition 13 marks.

[0135] Specifically, the heating zone 13 mark refers to a mark used to identify the position of different heating zones 13 inside the furnace body 5. These marks can help the robot arm 8 accurately place the glass pieces in each heating zone 13 to ensure that each glass piece can be tempered under the best heating environment. The controller generates multiple heating zone 13 marks according to the number and size of the tempered glass pieces. These marks can be numbers, letters or other symbols, and can also be displayed on an electronic display screen. The controller calculates the required number of heating zones 13 according to the number and size of the tempered glass pieces, and generates corresponding heating zone 13 marks. The controller sends the generated heating zone 13 marks to the robot arm 8, and the robot arm 8 completes the placement of multiple glass pieces according to these marks. The robot arm 8 identifies the heating zone 13 marks through a visual sensor to ensure the accuracy of the placement position. The robot arm 8 adjusts its own height and angle according to the mark information sent by the controller to accurately place the glass pieces in the designated heating zone 13. The controller calculates the required number of heating zones 13 according to the number of tempered glass pieces and the size of each piece of glass. For example, if a batch needs to process 10 pieces of glass, such as Figure 2As shown, the controller may form a tempering area 12 inside the furnace body 5 and divide it into 10 heating zones 13, each zone corresponding to a piece of glass. The controller generates a mark for the heating zone 13, which may be a letter (a, b, c, ...) or other symbols. When the marks corresponding to the heating zone 13 are a and b respectively, the controller sends the generated mark for the heating zone 13 to the robot 8, instructing the robot 8 to place the glass piece in the designated heating zone 13. For example, the controller sends an instruction: "Place the first piece of glass in the heating zone 13 marked as a, the second piece of glass in the heating zone 13 marked as b, and so on." The robot 8 identifies the marks of the heating zones 13 inside the furnace body 5 through a visual sensor. According to the placement instruction sent by the controller, the robot 8 adjusts its position and posture, and accurately places the glass piece in the designated heating zone 13 marked as a. For example, the robot 8 places the first piece of glass in the designated position of the heating zone 13 marked as a according to the mark 1 of the heating zone 13. During the operation of the robot 8, the controller can monitor the placement of the glass piece in real time through the sensor. If the placement is found to be incorrect, the controller will adjust the instructions in time to ensure that each glass piece can be placed correctly. Real-time monitoring can also record the placement of each heating zone 13, which is convenient for subsequent quality tracing and analysis.

[0136] By identifying the marks of the heating partitions 13 through the visual sensor, the robot arm 8 can more accurately locate the placement position of the glass piece, reducing the placement error. Each heating partition 13 has a clear mark, which can avoid overlap between glass pieces and ensure that each piece of glass can be tempered under the best heating conditions. The heating partition 13 marks generated by the controller enable the robot arm 8 to process multiple glass pieces at the same time, realizing batch processing and improving production efficiency. The robot arm 8 quickly completes the placement operation of the glass piece according to the precise placement instructions, reducing the downtime caused by inaccurate placement. Each heating partition 13 has a clear mark, and the controller can independently control the temperature of each partition to ensure the uniformity of heating of the glass piece at different positions. Through partition control, local overheating or overcooling can be avoided, and the uniformity and quality of tempered glass can be improved. The controller can monitor the placement of the robot arm 8 and the heating status of the furnace body 5 in real time, adjust the parameters in time, and reduce the defective rate caused by improper operation.

[0137] Exemplarily, it also includes: the controller determines the edge heating zone 13 mark and the center heating zone 13 mark according to the multiple heating zone 13 marks, and the controller controls the robot arm 8 to first place the glass piece corresponding to the edge heating zone 13 mark, and then places the glass piece corresponding to the center heating zone 13 mark.

[0138] The controller determines which partitions are edge partitions and which are center partitions according to the geometric structure and temperature distribution characteristics of the furnace body 5. The edge partitions are usually located around the furnace body 5, and the temperature distribution may be uneven due to the influence of the furnace wall. The center partition is located in the middle area of ​​the furnace body 5, and the temperature distribution is more uniform. The controller generates a placement instruction to instruct the robot arm 8 to first place the glass piece corresponding to the mark of the edge heating partition 13, and then place the glass piece corresponding to the mark of the center heating partition 13. For example, the controller will send an instruction: "Place the first glass piece in the heating partition 13 marked as a (edge ​​partition), and place the second glass piece in the heating partition 13 marked as b (edge ​​partition), and so on, until all the glass pieces in the edge partition are placed, and then place the glass pieces in the center partition." The robot arm 8 recognizes the mark of the heating partition 13 through the visual sensor, and first places the glass piece at the specified position of the edge partition. After completing the placement of the edge partition, the robot arm 8 continues to recognize the mark of the center heating partition 13 and places the glass piece at the specified position of the center partition.

[0139] By distinguishing between edge and center heating zones 13, the controller can independently control the temperature of each zone to ensure uniform temperature distribution. Placing the glass pieces in the edge zones first can reduce temperature fluctuations in the edge areas and avoid affecting the tempering effect of the edge glass pieces. The separate control of the edge zones and the center zones allows each glass piece to be tempered under optimal conditions, improving the uniformity and quality of the tempered glass.

[0140] In some embodiments, it also includes: multiple heating modules, each of which is used to heat one of the heating zones 13; wherein the glass sheet parameters include at least the material of the glass sheet, the thickness of the glass sheet and the purpose of the glass sheet; the controller determines the required degree of tempering of the glass sheet according to the purpose of the glass sheet; the controller generates initial heating temperature values ​​corresponding to the tempering temperature curves of the multiple glass sheets according to the glass sheet thickness, heating parameters, tempering time and purpose of the glass sheets corresponding to the multiple glass sheets; generates a zone heating temperature value corresponding to each heating zone 13 according to the zone position corresponding to each heating zone 13 and the initial heating temperature value; the controller controls the corresponding heating module according to the zone heating temperature value to complete the heating of the glass sheet.

[0141] For example, use a spectrometer to identify the material of the glass. Use an infrared thickness sensor to measure the thickness of the glass. Obtain the purpose of the glass through an input interface or database. The controller searches for the corresponding tempering degree requirements from the preset tempering standard database based on the purpose of the glass. For example, the tempering degree requirement for a car windshield may be 500MPa, and the tempering degree requirement for architectural glass may be 300MPa.

[0142] For example, the heating temperature value of the edge zone may be slightly higher to compensate for the cooling effect of the furnace wall; the heating temperature value of the center zone may be slightly lower to avoid local overheating. The controller controls the temperature setting of each heating module based on the generated zone heating temperature value. For example, the controller can send a command to the heating module to set its heating temperature to 655°C. It can also send a command to the heating module to set its heating temperature to 650°C.

[0143] By determining the required degree of tempering according to the purpose of the glass piece, the controller can adjust the heating temperature and time more accurately to ensure that each piece of glass can achieve the best tempering effect. Considering the influence of the furnace wall and the temperature distribution characteristics, the zone heating temperature value generated by the controller makes the temperature distribution of each heating zone 13 more uniform, improving the overall quality of the tempered glass. Each glass piece has a corresponding initial heating temperature value, and the zone heating temperature value is generated after adjustment according to the zone position, realizing personalized heating settings. Each heating module independently controls the temperature of the heating zone 13, avoiding the temperature fluctuation of the traditional single heating area, and improving the stability and controllability of the heating process. Through the independent control of multiple heating modules, the controller can process multiple glass pieces at the same time, realizing batch processing and improving production efficiency. The controller can quickly adjust the heating parameters according to the actual production situation, reducing the downtime caused by improper temperature adjustment. Each heating module independently controls the temperature, avoiding energy waste caused by uneven temperature distribution, and improving energy utilization. By optimizing the heating process, the controller ensures that each glass piece can be tempered under the best conditions, reducing unnecessary heating time, and further saving energy.

[0144] For example, the initial heating temperature value can be expressed as follows:

[0145] ;

[0146] is the initial heating temperature value, is the heating power, is the heating efficiency, is the tempering time, The controller calculates the initial heating temperature value required for each piece of glass according to the thickness of the glass sheet, heating parameters (such as heating power and heating efficiency) and tempering time. The controller adjusts the initial heating temperature value according to the partition position of each heating partition 13, taking into account the influence of the furnace wall and the temperature distribution characteristics, and generates the partition heating temperature value of each heating partition 13.

[0147] Exemplarily, the controller adjusts the partition heating temperature value corresponding to the heating partition 13 determined as the central partition according to the partition position to be greater than the initial heating temperature value, and the ratio of the partition heating temperature value of the central partition to the initial heating temperature value is within a preset ratio range, and the preset ratio range is 5% to 20%.

[0148] The temperature measurement module 14 is arranged in each heating zone 13, and the distance from the surface of the glass sheet is less than the preset distance, which ensures the accuracy of the temperature measurement. By measuring at close range, the actual temperature of the surface of the glass sheet can be more accurately reflected, avoiding the temperature error caused by the long measurement distance. The controller can dynamically adjust the temperature setting of the heating module according to the temperature value monitored in real time to ensure that the temperature of each zone remains within the set range. Through real-time adjustment, it can be ensured that the temperature distribution of each zone in the furnace body 5 is more uniform, and the tempering quality is improved. The controller can quickly adjust the temperature of the heating module according to the temperature value monitored in real time, reducing the production downtime caused by temperature fluctuations. Real-time monitoring and dynamic adjustment ensure the continuity and stability of the production process and improve production efficiency.

[0149] Exemplarily, it also includes: multiple temperature measurement modules 14, each of which is arranged in one of the heating zones 13; the controller is used to control the corresponding heating module to complete the heating of the glass sheet according to the temperature value measured by the temperature measurement module 14 and the zone heating temperature value; wherein the distance between the temperature measurement module 14 and the surface of the glass sheet is less than a preset distance, and / or the distance between the temperature measurement module 14 and the heating module corresponding to the heating zone 13 is less than a preset distance.

[0150] By setting a temperature measurement module 14 in each heating zone 13 and ensuring that the distance from the glass sheet surface and the heating module is less than a preset distance, the accuracy of temperature monitoring can be improved, the heating process can be optimized, the uniformity of temperature distribution can be ensured, the production efficiency can be improved, the cost can be reduced, and the equipment utilization rate can be improved.
