Description

Technical Field

[0001] This invention relates to the field of glass substrate processing technology, specifically to a cutting device that reduces the failure rate of cutting machines. Background Technology

[0002] A glass cutting machine is a high-precision mechanical device specifically designed to cut glass materials into specific sizes and shapes. It is widely used in various industries, such as construction, automobile manufacturing, furniture making, and decoration. Its core components include a cutting head, a cutting platform, a control system, and a cooling system. The cutting head is typically made of high-hardness materials, enabling precise and rapid cutting operations. The cutting platform is generally constructed of flat and robust materials to ensure the glass remains stable during the cutting process. Glass cutting machines can be categorized into three types based on their level of automation and operating method: manual, semi-automatic, and fully automatic. Manual glass cutting machines rely on the operator's skills and experience and are suitable for small-scale, uncomplicated cutting tasks. Semi-automatic glass cutting machines combine manual operation with some automation functions and are suitable for medium-scale production needs. Fully automatic glass cutting machines are controlled by Computer Numerical Control (CNC) technology, enabling precise execution of complex cutting patterns, significantly improving production efficiency and product quality.

[0003] Existing glass cutting machines generate a lot of heat and glass shards during the cutting process, which fall onto the cutting table. The heat generated not only causes heat buildup in the machine, affecting its lifespan, but can also cause localized thermal expansion of the glass, leading to deformation of the cut surface or crooked cut lines. These problems seriously affect cutting accuracy and product quality. For example, the glass cutting machine proposed in Chinese patent CN210457957U includes a cutting table, a guide rail, and a cutting bridge. The cutting table includes legs and a tabletop. The cutting bridge includes a bridge body and a cutting head. The cutting bridge is supported on the cutting table and slidably connected to the guide rail. A through groove is formed on the cutting table, and a support platform is installed within the through groove. A rotating mechanism is connected to the bottom of the support platform to drive the platform to tilt within the through groove. A cleaning bridge is connected to the cutting table, and a first brush rod is slidably connected to the cleaning bridge. A brush is connected to the side of the first brush rod opposite to the cleaning bridge. The first brush rod is perpendicular to the cleaning bridge, and a motor is installed in the cleaning bridge to drive the movement of the first brush rod. Although the cutting machine can clean glass shards using a brush, the process requires rotating the support platform by a rotating rod. The glass shards are then swept into the collection bin by their own weight and the brush. The support platform must then be restored to its original position. This process is complex and cumbersome. Repeated use of this method to clean glass shards can cause severe wear between structural components, leading to a significant increase in equipment failure rate. Furthermore, the machine can generate heat buildup, a common problem with traditional equipment, during the processing. Summary of the Invention

[0009] Preferably, drive motors are provided at both ends of the rotating shaft, and the drive motors are fixedly mounted on the fixed structure.

[0010] Preferably, the adsorption rod is arrayed with a plurality of adsorption disks, which adsorb the glass substrate when the glass substrate is clamped.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a cutting device that reduces the failure rate of cutting machines, and has the following beneficial effects:

[0018] 1. This cutting equipment, designed to reduce the failure rate of cutting machines, utilizes a combination of a support plate structure, a support airbag structure, and an air pump module structure. Compared to traditional glass cutting equipment, which accumulates heat on the glass substrate surface after prolonged operation, affecting heating efficiency, and the support plate also experiences heat buildup leading to increased failure rates, this equipment, during processing, transfers heat generated on the glass substrate surface to the support plate. Since the support plate is connected to the support airbag, and the air inside the airbag is a flowing gas generated by the air pump module, the heat from the rising support plate is transferred to the gas within the airbag. This flowing gas carries away the heat and discharges it through the air pump module, effectively reducing the temperature of the support plate and its surroundings and preventing heat accumulation. This design helps avoid equipment failures due to overheating and thermal stress damage to the glass substrate, thereby improving the reliability and processing quality of the cutting equipment and effectively reducing the failure rate.

[0019] 2. This cutting equipment, designed to reduce the failure rate of cutting machines, utilizes a combination of an air hole structure, an air pump module structure, and a shaft hole structure. Compared to traditional technical structures where impurities easily enter the shaft hole, leading to equipment malfunctions, this equipment, with its air holes and shaft holes connected and sealed at both ends of the shaft hole, allows for a significant increase in gas pressure in the air holes and shaft hole during air pump module operation. This pressure rises above the external atmospheric pressure, creating a pressure difference from the inside to the outside. Air always flows from the high-pressure area to the low-pressure area. Therefore... The internal and external pressure difference prevents external impurities from entering the gap between the shaft hole and the rotating shaft with the air. When the high-pressure gas flows outward from the air hole and shaft hole, it forms an outward airflow barrier at the gap. This airflow barrier can effectively block external impurities from entering, acting like an "air curtain". At the same time, the high-pressure gas will discharge internal impurities, further reducing internal pollution sources, thereby maintaining the cleanliness and normal operation of the equipment. The reduction of impurities also protects the purity of the lubricant, ensuring that the lubrication effect is not compromised, thereby reducing friction and heat accumulation, improving the operating efficiency and reliability of the equipment, and thus reducing the equipment failure rate.

[0020] 3. This cutting equipment, designed to reduce the failure rate of cutting machines, utilizes a combination of a support plate structure, a support airbag structure, an air pump module structure, and a slag removal port structure. Compared to traditional technologies where glass fragments remain on the support plate after glass substrate processing, affecting the quality of subsequent glass substrate processing, this equipment reduces failure rates by ejecting gas from the slag removal port. The ejected gas collides with the slightly raised glass substrate, and the gas diffuses horizontally after the collision. This diffusion process generates a diffusion airflow, which blows the glass fragments that have fallen on the support plate below the support platform, reducing the amount of glass fragments on the support plate and preventing scratches on the glass substrate during subsequent processing. Furthermore, this simple design eliminates the need for complex structures and cumbersome processes, effectively reducing equipment failure rates and costs while extending its service life.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A cutting device for reducing the failure rate of a cutting machine includes a support platform 1, a cutting module, and a clamping module. The cutting module is slidably mounted above the support platform 1, allowing it to move freely above the support platform 1 and cover the entire working area of ​​the support platform 1. This flexibility allows cutting at any position on the glass substrate 7, adapting to substrates of different sizes and shapes, improving the versatility and cutting efficiency of the equipment. The sliding design extends the working range of the cutter 33, avoiding the problem of the fixed cutting head not being able to reach the entire glass substrate 7. The cutter 33 can move along the length and width of the support platform 1 via the sliding guide rail 32, thereby achieving a complete and precise cutting operation. A clamping module for clamping the glass substrate 7 to be processed is rotatably mounted on one side of the support platform 1. The rotating clamping module allows the operator to easily clamp the glass substrate 7 onto or remove it from the equipment. This design reduces the difficulty of manual operation, especially when handling large or heavy glass substrates 7, significantly improving work efficiency and safety. The rotating design enables the glass substrate 7 to automatically center during clamping and remain stable during processing. The cooperation of the fixing structure 22 and the suction plate 25 ensures that the substrate does not shift during the cutting process, thereby improving cutting accuracy and consistency and avoiding cutting errors caused by substrate displacement. A vertically adjustable support plate 41 is slidably mounted above the support table 1. The adjustable support plate 41 allows for height adjustment according to different thicknesses of the glass substrate 7, ensuring that glass substrates of different thicknesses are always in the optimal position during processing. This ensures that the cutter 33 applies uniform pressure during cutting, avoiding cutting quality problems caused by inconsistent thickness. The support plate 41 can be slidably adjusted at different heights, enabling smooth movement and precise positioning during the support and transport of the glass substrate 7. This design facilitates efficient clamping and unloading of the glass substrate 7 before and after cutting operations. An inflatable support airbag 5 is fixed between the support plate 41 and the support table 1. An air pump module 6 is connected to the support airbag 5. The inflatable support airbag 5 provides effective shock absorption and cushioning, protecting the glass substrate 7 from vibration and impact during processing. This helps prevent the substrate from cracking or being damaged during cutting, improving the yield rate. The air pump module 6 controls the inflation and deflation of the support airbag 5, and can precisely adjust the height and support force of the support plate 41 to meet the processing requirements of glass substrates 7 of different sizes and thicknesses.Furthermore, during the processing, when the surface of the glass substrate 7 generates heat during cutting, this heat is transferred to the support plate 41. Since the support plate 41 is connected to the support airbag 5, and the gas inside the support airbag 5 is flowing gas generated by the air pump module 6, the heat generated by the rising temperature of the support plate 41 is transferred to the gas inside the support airbag 5. This flowing gas carries away the heat and is discharged through the air pump module 6, effectively reducing the temperature of the support plate 41 and its surroundings, preventing heat accumulation. This design helps avoid equipment failure and thermal stress damage to the glass substrate 7 caused by overheating, thereby improving the reliability and processing quality of the cutting equipment and effectively reducing the equipment failure rate. A pressure sensor is installed inside the support airbag 5 to monitor the internal pressure. The pressure sensor can monitor the internal pressure of the support airbag 5 in real time, ensuring that the airbag operates within a safe pressure range and preventing equipment failure or damage to the glass substrate 7 due to over-expansion or insufficient pressure. This monitoring can prevent potential risks and improve equipment safety. By monitoring air pressure, the air pump module 6 can precisely control the inflation volume of the support airbag 5, thereby controlling the height and supporting force of the support plate 41. This precise control helps ensure the stability of the glass substrate 7 during cutting, improving processing accuracy and quality. When the support airbag 5 inflates, it supports the support plate 41 and the glass substrate 7 on it. The inflated support airbag 5 provides a stable and uniform supporting force, smoothly lifting the support plate 41 and the glass substrate 7. This stable support helps reduce errors caused by substrate vibration or movement during cutting, improving cutting quality.

[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6The clamping module includes an adsorption rod 21, a fixing structure 22, and a rotating shaft 23. Several fixing structures 22 are arrayed on the side of the support plate 41, with gaps between them. This array of fixing structures 22 evenly distributes the supporting force, ensuring the support plate 41 remains stable during processing. This design disperses the pressure on the support plate 41, preventing deformation or breakage that might occur due to single-point stress, thereby improving cutting accuracy and equipment stability. The fixing structure 22 has a through-hole 24, within which the rotating shaft 23 is coaxially rotatably mounted. The through-hole 24 allows the rotating shaft 23 to rotate freely, thus enabling the adsorption rod 21 to rotate. This ensures the adsorption rod 21 can rotate flexibly, guaranteeing a smooth and accurate adsorption and release process for the glass substrate 7. The coaxial design ensures high precision and stability of the rotating shaft 23 during rotation, avoiding the influence of rotational deviation on the position of the adsorption rods 21, thereby ensuring the positioning accuracy of the glass substrate 7 during processing and improving cutting quality. Several adsorption rods 21 are rotatably positioned at intervals, with the rotating shaft 23 fixedly connected to the adsorption rods 21. Each adsorption rod 21 is spaced apart, and the support airbags 5 are positioned between these intervals. This spacing between the adsorption rods 21 helps to evenly distribute the supporting force, ensuring uniform stress on the glass substrate 7 during processing, reducing the risk of deformation or breakage due to uneven local stress, and improving cutting accuracy. The support airbags 5, positioned between the adsorption rods 21, avoid mutual interference between the adsorption rods 21 and the support airbags 5, ensuring the normal expansion and contraction of the support airbags 5, and improving the working efficiency and stability of the airbags. Please refer to [link / reference]. Figure 5 and Figure 7When the support airbag 5 is not inflated, the height of the support plate 41 is less than the height of the adsorption rod 21 when it is horizontal. When the support airbag 5 is inflated, the height of the support plate 41 is higher than the height of the adsorption rod 21 when it is horizontal. When the support airbag 5 is not inflated, the height of the support plate 41 is lower than the adsorption rod 21, ensuring that the glass substrate 7 can be stably adsorbed by the adsorption rod 21. When the support airbag 5 inflates, the support plate 41 rises, smoothly supporting the glass substrate 7, achieving a smooth transition from adsorption to support, and preventing the substrate from shaking or falling during the conversion process. This design allows the equipment to flexibly switch between adsorption and support modes between different operating modes, ensuring optimal support for the glass substrate 7 at different processing stages, improving processing quality and equipment efficiency. The gap distance is equal to the width of the adsorption rod 21, and the interval distance is greater than the width of the support plate 41. The gap distance being equal to the width of the adsorption rod 21 ensures that the adsorption rod 21 is not interfered with by other structures during rotation, achieving precise adsorption and release. The interval distance being greater than the width of the support plate 41 ensures that the support airbag 5 can effectively inflate between the adsorption rods 21 and support the glass substrate 7. This design optimizes the space utilization above the support platform 1, ensuring that all components do not interfere with each other during operation, maintaining the compactness and efficiency of the equipment. It also facilitates maintenance and cleaning, improving the overall operational reliability of the equipment. Several adsorption plates 25 are arrayed on the adsorption rod 21. When clamping the glass substrate 7, the adsorption plates 25 adsorb the glass substrate 7. The multiple adsorption plates 25 on the adsorption rod 21 increase the contact area with the glass substrate 7, thereby enhancing the adsorption force. The multiple adsorption plates 25 work together to ensure the glass substrate 7 is firmly fixed during clamping, preventing slippage or falling. The multiple adsorption plates 25 can evenly distribute the adsorption force, avoiding localized stress concentration caused by a single adsorption point, reducing the risk of substrate deformation or breakage, and improving processing quality. When the adsorption rod 21 is horizontal, its height is less than the edge height of the support platform 1; when the adsorption rod 21 is horizontal, its height is lower than the edge of the support platform 1. This avoids interference with other components when not in operation, ensuring the safe and smooth operation of the equipment under different working conditions. The adsorption rod 21 is positioned below the edge of the support platform 1, protecting the adsorption plate 25 from external damage or contamination, extending its service life, and ensuring stable and reliable adsorption performance. Drive motors 27 are mounted at both ends of the rotating shaft 23, and are fixedly mounted on the fixed structure 22. The drive motors 27 control the rotation of the rotating shaft 23, enabling automated rotation of the adsorption rod 21, improving the automation level of the equipment, reducing manual operation, and increasing work efficiency.

[0033] Please see Figure 5The fixed structure 22 is also provided with an air hole 26 that penetrates through it. The air hole 26 is perpendicular to and communicates with the shaft hole 24, and one end of the air hole 26 is connected to the support airbag 5. The design of the air hole 26 provides a channel for gas flow between the support airbag 5 and the shaft hole 24, ensuring that the gas generated by the air pump module 6 can smoothly enter the support airbag 5, ensuring its normal expansion and contraction, and improving working efficiency. The air hole 26 is connected to the shaft hole 24, which can block external impurities from entering the equipment through the airflow barrier, protecting the internal structure of the equipment and the purity of the lubricant, reducing wear and failure rate. The air pump module 6 is fixedly installed at the other end of the air hole 26. The air pump module 6 is the main source of gas required for the expansion of the support airbag 5. By fixing it to one end of the air hole 26, it ensures that the gas can be smoothly delivered to the support airbag 5, ensuring normal operation of the equipment. The fixed installation of the air pump module 6 ensures that it can stably provide air pressure during operation, avoiding the impact of air pressure fluctuations on the expansion effect of the support airbag 5, and improving the stability and reliability of the equipment. Sealing rings are provided at both ends of the shaft hole 24. These sealing rings effectively prevent gas leakage between the air hole 26 and the shaft hole 24, ensuring stable air pressure and supporting the normal expansion of the air bladder 5, thus improving equipment efficiency. The sealing rings also prevent external impurities and contaminants from entering the shaft hole 24, protecting the internal structure and the purity of the lubricant, reducing wear and malfunctions, and improving the equipment's service life and reliability.

[0034] Please see Figure 6 The surface of the support plate 41 is also provided with several slag removal ports 42 that are connected to the support airbag 5.

[0035] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6The cutting module includes a sliding crossbar 31, guide rails 32, and a cutter 33. Guide rails 32 are mounted at both ends of the support platform 1, providing more stable support and preventing the sliding crossbar 31 from tilting or wobbling during movement. This ensures the cutter 33 slides smoothly along the guide rails 32, improving processing accuracy. The guide rails 32 support the sliding crossbar 31 at both ends, evenly distributing the weight and force of the sliding crossbar 31 and the cutter 33, reducing the stress on a single guide rail 32 and extending the equipment's lifespan. The sliding crossbar 31 is positioned above the support platform 1, with a minimum height higher than the support platform 1. This ensures that the sliding crossbar 31 and the cutter 33 will not interfere with the support platform 1 or the glass substrate 7 on it during operation, guaranteeing smooth cutting. The fact that the sliding crossbar 31 is higher than the support platform 1 allows it to accommodate glass substrates 7 of different thicknesses, ensuring successful cutting regardless of substrate thickness and improving the equipment's versatility. Furthermore, the two ends of the sliding crossbar 31 are slidably connected to the guide rail 32, and the cutter 33 is slidably mounted on the sliding crossbar 31. The connection of the two ends of the sliding crossbar 31 to the guide rail 32 ensures that the sliding crossbar 31 moves along a fixed trajectory, achieving precise positioning and movement of the cutter 33, thus improving cutting accuracy and consistency. The slidable mounting of the cutter 33 on the sliding crossbar 31 allows the cutter 33 to move freely along the sliding crossbar 31, facilitating adjustment of the cutting position and adapting to glass substrates 7 of different sizes and shapes, thereby enhancing the operational flexibility of the equipment.

[0036] Working principle: In use, the drive motor 27 first rotates the adsorption rod 21 to a vertical position, allowing it to adsorb the glass substrate 7 through the adsorption plate 25. Then, the drive motor 27 restarts, resetting the adsorption rod 21 to a horizontal position. Next, the air pump module 6 inflates the support airbag 5, causing it to expand longitudinally. This raises the support plate 41 mounted above it, simultaneously releasing the adsorption plate 25 from the glass substrate 7, thus changing the structure fixing the glass substrate 7 from the adsorption plate 25 to the support plate 41. The glass substrate 7 is then processed using the cutter 33.

[0037] During processing, when heat is generated on the surface of the glass substrate 7 during cutting, this heat is transferred to the support plate 41. Since the support plate 41 is connected to the support airbag 5, and the gas inside the support airbag 5 is flowing gas generated by the air pump module 6, the heat generated by the rising temperature of the support plate 41 is transferred to the gas within the support airbag 5. This flowing gas carries away the heat and discharges it through the air pump module 6, effectively reducing the temperature of the support plate 41 and its surroundings and preventing heat accumulation. This design helps avoid equipment failure and thermal stress damage to the glass substrate 7 caused by overheating, thereby improving the reliability and processing quality of the cutting equipment and effectively reducing the equipment failure rate.

[0038] Since the vent 26 is connected to the shaft hole 24, and both ends of the shaft hole 24 are equipped with sealing rings, during the operation of the air pump module 6, when the air pump module 6 is filled with air, the gas pressure in the vent 26 and shaft hole 24 will increase and exceed the external atmospheric pressure. When the gas pressure in the vent 26 and shaft hole 24 is higher than the external atmospheric pressure, a pressure difference is formed from the inside to the outside. Air always flows from the high-pressure area to the low-pressure area, so the pressure difference between the inside and outside will prevent external impurities from entering the gap between the shaft hole 24 and the rotating shaft 23 with the air. Furthermore, when the high-pressure gas flows outward from the vent 26 and shaft hole 24, it will form an outward airflow barrier at the gap. This airflow barrier can effectively block external impurities from entering, acting similarly to an "air curtain". At the same time, the high-pressure gas will expel internal impurities, further reducing internal pollution sources, thereby maintaining the cleanliness and normal operation of the equipment. Furthermore, reducing the entry of impurities also protects the purity of the lubricant, ensuring that the lubrication effect is not compromised, thereby reducing friction and heat accumulation, improving the operating efficiency and reliability of the equipment, and ultimately reducing the equipment failure rate.

[0039] After the glass substrate 7 is processed, the drive motor 27 is activated to rotate the adsorption rod 21, causing the adsorption plate 25 to adhere to the processed glass substrate 7 and slightly lift the glass substrate 7. As the glass substrate 7 is lifted by the adsorption rod 21, the weight above the support plate 41 decreases, resulting in reduced pressure on the support plate 41. Meanwhile, the air pressure inside the support airbag 5 is high, and it will further expand under the reduced external pressure. This is because the high-pressure gas inside the support airbag 5 is no longer suppressed by the glass substrate 7 above, and the airbag tends to expand to a new equilibrium state. However, since the slag removal port 42 on the support plate 41 is not blocked by the glass substrate 7, some gas will be ejected from the slag removal port 42. The ejected gas will first collide with the slightly lifted glass substrate 7. Since the gas flow direction is vertically upward, the gas will diffuse horizontally after the collision. This diffusion process generates a certain diffusion airflow. During the gas diffusion process, the gas will blow the glass fragments that fall on the support plate 41 down below the support platform 1, reducing the amount of glass fragments on the support plate 41 and preventing scratches on the glass substrate 7 during subsequent processing. At the same time, because this design structure is simple and does not require complex structures and cumbersome processes, it effectively reduces the equipment failure rate and equipment cost, and increases its service life.
