[0031] The aforementioned power supply device is powered by connecting to an external power source;

[0032] The correction device 13 includes a fixing plate 1 at both ends, a drive motor 2, a drive nut 3, an anti-detachment ring 4, a screw 5, a rubber roller 6, and a metal roller 7.

[0033] A drive motor 2 is installed on the upper side of the fixed plate 1. A screw 5 is connected to the upper middle position of the drive motor 2. An anti-detachment ring 4 is installed at the upper end of the screw 5. A drive nut 3 is threadedly connected to the outer side of the screw 5. A rubber roller 6 is externally connected to one side of the drive nut 3. A metal roller 7 is externally connected to one side of the drive motor 2.

[0034] An accelerating conveyor belt 19 is installed on the left side of the conveyor roller 12. A pressure roller mechanism 20 is installed on the upper left side of the accelerating conveyor belt 19. An edge cleaning machine 21 is installed on the left side of the pressure roller mechanism 20. A rotating device 22 is installed on the left side of the edge cleaning machine 21. A static breaking rod 23 is installed on the left side of the rotating device 22. A powder spraying machine 24 is installed on the left side of the static breaking rod 23. Three air cushion tables 29 are installed at the left end and the outer side of the accelerating conveyor belt 19.

[0035] Two air cushion tables 29 are installed at the end of the side facade acceleration conveyor belt 19, and an overpass steering machine 30 is installed at the connection position of the two overpass steering machines 30 and the air cushion tables 29. A belt conveyor 28 is installed at the connection position of the two overpass steering machines 30 and the air cushion tables 29, and a static break bar 23 is installed on the upper side of the connection between the end of the two air cushion tables 29 and the end of the acceleration conveyor belt 19.

[0036] A robotic arm 25 is provided on the front side of the rotating device 22. A protective railing 26 is provided on the outer side of the robotic arm 25. Multiple stacking platforms 27 are provided on the inner side of the protective railing 26.

[0037] In this embodiment, the intelligent cold-end inspection, cutting and packing system for borosilicate float glass achieves fully automated operation from glass inspection and cutting to packing through the coordinated work of multiple structures, ensuring that the glass products meet quality standards and are packaged efficiently.

[0038] First, the borosilicate float glass's motion information after exiting the annealing furnace is recorded by encoder 8, providing a data basis for subsequent processes. Next, the glass passes through air-blowing cleaning device 9 on conveyor rollers 12, where the airflow cleans impurities and dust from the glass surface, preventing them from affecting subsequent inspection and processing accuracy. A glass breakage detector 10 monitors in real time for potential glass breakage hazards, immediately issuing an alarm upon detecting any abnormality. Personnel in the manual inspection room 11 can perform further visual inspections of the glass, supplementing automated inspection and ensuring glass quality.

[0039] After initial inspection, the glass enters the straightening device 13. If the glass is bent or deformed, the drive motor 2 starts according to a preset program or a received external signal, driving the screw 5 to rotate. The drive nut 3 on the screw 5 moves up and down due to its threaded engagement, thereby adjusting the distance between the rubber roller 6 and the metal roller 7. As the glass passes between the two rollers, the elasticity of the rubber roller 6 and the squeezing force of the upper and lower rollers are used to straighten the glass's flatness, preparing it for subsequent precise cutting. The straightened glass then passes through the speed measuring wheel 14, which measures the glass's transmission speed and feeds this speed information back to the control system so that the subsequent cutting equipment can perform precise cutting based on the glass's speed.

[0040] The longitudinal slicing machine 15 and the transverse slicing machine 16 cut the glass according to preset dimensions based on instructions from the control system. The longitudinal slicing machine 15 first cuts the glass longitudinally, dividing the large sheet into strips of predetermined width. Then, the transverse slicing machine 16 cuts the glass transversely, slicing the strips into specifications that meet customer requirements. After cutting, the glass passes through a marking bridge 17. Based on the inspection results and preset information, the marking bridge 17 marks the glass surface with product information such as specifications, batch number, and grade, facilitating subsequent identification and management. The marked glass then reaches the main breaking rod 18, which applies external force to the cut glass, causing it to break smoothly along the cutting line, forming individual glass products.

[0041] The broken glass is conveyed at an accelerated speed via the conveyor belt 19, improving production efficiency. Above and to the left of the conveyor belt 19, a pressure roller mechanism 20 further presses and stabilizes the glass, ensuring accurate positioning during transport. The glass then enters the edge cleaning machine 21, which removes burrs, debris, and other defects from the glass edges, improving edge quality. After edge cleaning, the glass passes through a rotating device 22, which can adjust the glass's orientation as needed to meet subsequent processing or storage requirements. The glass then passes through a static breaking rod 23 to process any incompletely separated or requiring secondary breaking. A powder sprayer 24 sprays protective powder onto the glass surface to prevent scratches during subsequent storage and handling. The processed glass is then conveyed to an air cushion table 29, which uses air cushions to support the glass, reducing friction between the glass and the tabletop and preventing surface damage. At the connection point between the air cushion table 29 and the conveyor belt 19, a vertical steering mechanism 30 and a belt conveyor 28 work together to turn and transport the glass, ensuring accurate placement on the air cushion table 29. Finally, under the protection of the guardrail 26, the robotic arm 25, following the instructions of the control system, transports the glass from the air cushion table 29 to the stacking platform 27 for storage and stacking, completing the entire production process.

[0042] like Figure 1-4As shown, an outer frame is provided on the outside of the conveyor roller 12. The fixing plate 1 is connected to the outer frame of the conveyor roller 12 by external bolts. The screw 5 rotates under the drive of the drive motor 2. The drive nut 3 moves up and down on the screw 5 through the thread. Two rubber rollers 6 and two metal rollers 7 are respectively fitted and connected. The rubber rollers 6 and the metal rollers 7 rotate on the outer side of the drive nut 3 and the drive motor 2 respectively.

[0043] Optionally, a pressure sensor is installed inside the connection position between the metal roller 7 and the drive motor 2 to detect the degree of glass deformation. The control system controls the drive motor 2, screw 5 and drive nut 3 mechanism to adjust the distance between the rubber roller 6 and the metal roller 7 based on the pressure data.

[0044] Preferably, the borosilicate float glass, driven by the conveyor roller 12, enters the correction device 13 between the manual inspection chamber 11 and the speed measuring wheel 14. At this time, the speed of the glass movement is monitored in real time by the speed measuring wheel 14 and fed back to the entire system to ensure that the correction process matches the glass transport rhythm.

[0045] When the glass contacts the rollers of the straightening device 13, the pressure sensor inside the lower metal roller 7 starts to operate. When the glass is bent or deformed, the pressure distribution between the glass and the rollers is uneven. The pressure sensor detects this pressure difference and converts the pressure data into an electrical signal. This electrical signal is transmitted to the control system via a circuit. The control system analyzes and processes this data to determine the bending direction and degree of deformation of the glass.

[0046] The control system sends commands to the drive motor 2 based on data from the pressure sensor. If the glass bends upward, the control system controls the drive motor 2 to rotate forward; if the glass bends downward, it controls the drive motor 2 to rotate in reverse. The output shaft of the drive motor 2 is connected to the screw 5, and the rotation of the motor drives the screw 5 to rotate. A drive nut 3 is fitted onto the screw 5. Because the drive nut 3 is connected to the bracket of the rubber roller 6 and is restricted by the guide structure rubber roller 6 connecting two drive nuts 3, the drive nut 3 cannot rotate with the screw 5, but can only move up and down along the axis of the screw 5. Thus, when the drive nut 3 moves upward, it drives the rubber roller 6 to rise, increasing the roller spacing; conversely, when the drive nut 3 moves downward, the rubber roller 6 descends, decreasing the roller spacing.

[0047] After the roller spacing is adjusted, the glass continues to move between the roller pairs under the push of the conveyor rollers. The upper roller 6, made of elastic rubber, fits tightly against the upper surface of the glass due to its own elasticity, while the lower roller 7 provides stable support for the glass. As the glass moves, the compressive force applied by the upper and lower rollers continuously acts on the curved parts of the glass. For upward-curving glass, the larger roller spacing, combined with the elastic pressure of the upper roller, gradually presses down the upward-curving part of the glass; for downward-curving glass, the smaller roller spacing strengthens the support and correction force for the downward-curving part of the glass. As the glass passes through the roller pairs, it is continuously subjected to this precise pressure adjustment, gradually restoring a flat state.

[0048] Throughout the process of the glass passing through the roller pair, a pressure sensor inside the lower roller 7 continuously monitors the pressure changes between the glass and the rollers and feeds the real-time data back to the control system. Based on this dynamic data, the control system continuously fine-tunes the rotation angle and speed of the drive motor 2, thereby precisely controlling the roller spacing. This continuous monitoring and dynamic adjustment mechanism ensures that the glass receives the most suitable straightening force throughout the entire straightening process, maximizing the flatness of the glass and providing a good foundation for the subsequent precise cutting by the longitudinal slicing machine 15 and the transverse slicing machine 16.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
