Description

Technical Field

[0001] This invention relates to the field of substrate glass manufacturing technology, specifically to a positioning mechanism for a substrate glass grinding machine. Background Technology

[0002] A substrate glass grinding machine is a precision grinding device used to process substrate glass. In the late 20th century, with the rapid development of the electronics industry, especially the dramatic increase in demand for semiconductor chips and liquid crystal displays, the demand for substrate glass also increased accordingly. To meet this demand, substrate glass grinding machines were developed. Initially, substrate glass grinding machines mainly used manual positioning, where operators manually adjusted the position of the grinding machine to grind the substrate glass. While simple, this method suffered from low precision and slow efficiency. In the 21st century, with the continuous development of automation technology, the positioning mechanism of substrate glass grinding machines gradually became automated. Automated positioning mechanisms based on robotic arms and CNC systems emerged. These automated positioning mechanisms, through high-precision sensors and control systems, can achieve high-precision and high-efficiency grinding processes. In recent years, with the rapid development of technologies such as artificial intelligence and machine learning, the positioning mechanism of substrate glass grinding machines has also been continuously upgraded. Intelligent positioning mechanisms based on machine vision and deep learning have emerged. These intelligent positioning mechanisms, through advanced algorithms and models, can achieve higher precision position control and faster speed adjustment, further improving the efficiency and precision of grinding processes.

[0003] Chinese patent CN201811327425.8 discloses a positioning mechanism for a substrate glass grinding machine that typically positions all four edges of the substrate glass at once before grinding. This method of positioning all four edges simultaneously means that the accuracy of positioning is affected by all four edges; any inaccurate positioning of any one edge will impact the subsequent grinding accuracy. This positioning method involves many variables, and with four edges being variables, the positioning accuracy will decrease accordingly. Furthermore, Chinese patent CN202110540237.9 discloses a single grinder. A single grinder has an excessively long travel distance when grinding the sides of the substrate glass, resulting in a prolonged grinding time. Finally, traditional substrate glass positioning devices and grinding devices are separate, requiring multiple steps for feeding, unloading, and positioning, making the operation cumbersome. Finally, in traditional two-sided positioning structures, the two sides move towards the middle simultaneously during positioning. Since the substrate glass is tilted before positioning is completed, when the two positioning mechanisms move towards the middle at the same time, the two opposite corners of the substrate glass can easily get stuck on the positioning mechanisms on both sides, resulting in damage to the substrate glass. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a positioning mechanism for a substrate glass grinding machine. This mechanism features simultaneous positioning of two substrate glass edges, reducing the number of influencing factors affecting the number of edges to be positioned, controlling fewer variables, and improving positioning accuracy. It also allows for simultaneous grinding by multiple grinders, saving time; feeding, grinding, and discharging are completed in one operation, simplifying operation; and the advantage of single-edge positioning followed by double-edge positioning prevents damage to the substrate glass from being squeezed by the positioning mechanism. This addresses the shortcomings of traditional substrate glass grinding machines, which often position all four edges of the substrate glass at once before grinding. This single-edge positioning means that positioning accuracy is affected by all four edges; any inaccurate positioning of any one edge will impact the subsequent grinding accuracy. This positioning method has many variables, with four sides being variables, which reduces positioning accuracy. The single grinder has an excessively long travel distance when grinding the side of the substrate glass, resulting in a long grinding time. Multiple processes are required for feeding, unloading, and positioning, making the operation cumbersome. Furthermore, when the positioning mechanisms on both sides move towards the center simultaneously, the two opposite corners of the substrate glass can easily get stuck on the positioning mechanisms on both sides, leading to damage to the substrate glass.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a positioning mechanism for a substrate glass grinding machine, which has the following advantages:

[0020] 1. The positioning mechanism of this substrate glass grinding machine works in conjunction with the positioning grinding frame. When the substrate glass to be ground is transported from the input module to the positioning grinding frame, because the top height of the rollers and connecting rollers is higher than the top height of the airflow disk, the substrate glass entering the positioning grinding frame from the input module will continue to move forward under the action of the rollers. When the substrate glass is completely inside the positioning grinding frame, the hub motor in the rollers will stop, and the positioning mechanism will then position the substrate glass. One of the positioning grinding claws on both sides will first move towards the center under the action of the positioning motor. When the pressure sensors simultaneously contact the side of the substrate glass, it indicates that the positioning of this side of the substrate glass is complete. If several pressure sensors do not simultaneously contact the side of the substrate glass, it indicates that the positioning of this side of the substrate glass is not complete, that is, the side of the substrate glass is in a tilted state, and the positioning grinding claw on this side needs to continue to move forward until the pressure sensors no longer simultaneously contact the side of the substrate glass, indicating that the positioning is complete. At this time, the positioning grinding claws on the other side will also move towards the center. When several pressure sensors on the positioning grinding claws on the other side simultaneously contact the other side of the substrate glass, it indicates that the positioning is complete, that is, the positioning of the substrate glass in the front-back direction is completed. At this time, the airflow disk on the positioning grinding frame will adsorb the substrate glass. After adsorption is complete, the grinder on the positioning grinding claws will grind the two corresponding sides of the substrate glass, and under the action of the front-back motion motor, it moves back and forth to ensure thorough grinding. After the two sides of the substrate glass are ground, the large suction cup adsorbs the substrate glass, the airflow disk releases the adsorption of the substrate glass, and the lifting motor starts to operate, lifting the substrate glass to a certain height. Then the rotation motor starts to operate, causing the substrate glass to rotate 90° and return to its original position, and then repositioning is performed. Finally, the two ends that have not been ground are ground. This achieves the effect of positioning the edges of two substrate glass at one time, reducing the influence of the number of positioning edges, controlling fewer variables, and improving positioning accuracy.

[0021] 2. The positioning mechanism of this substrate glass grinding machine works in conjunction with a positioning grinding frame. Multiple grinding blades are arranged side-by-side to grind the sides of the substrate glass. Their concave grinding surfaces grind the edges of the substrate glass sides, and the positioning grinding claws move back and forth on the sides of the substrate glass under the action of a front-and-back motion motor, enabling rapid grinding of the substrate glass sides. This achieves the effect of multiple grinding blades grinding simultaneously, saving time.

[0022] 3. The positioning mechanism of this substrate glass grinding machine works in conjunction with the positioning grinding frame. When the substrate glass enters the positioning grinding frame, its weight causes the spring roller to be pressed downwards by the weight of the substrate glass. At this time, the lower surface of the substrate glass will contact the upper end of the airflow disk, making it difficult for the substrate glass to move forward. The airflow disk then blows air upwards, maintaining a certain distance between the substrate glass and the upper end of the airflow disk, allowing the substrate glass to move forward smoothly. After the substrate glass has been processed, the airflow disk continues to blow air upwards, and then the hub motor starts operating, allowing the substrate glass to smoothly enter the output module from the positioning grinding frame. This achieves a one-time completion of feeding, grinding, and discharging, resulting in simple operation.

[0023] 4. The positioning mechanism of this substrate glass grinding machine works in conjunction with the positioning grinding frame. Furthermore, this single-sided positioning method prevents the substrate glass from being jammed at its two opposite corners by the positioning mechanisms during simultaneous positioning on both sides, thus avoiding damage. This achieves the effect of single-sided positioning followed by double-sided positioning, preventing the substrate glass from being crushed and damaged by the positioning mechanisms.

Detailed Implementation

[0041] 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.

[0042] Please see Figure 1-13 A positioning mechanism for a substrate glass grinding machine includes an input module 1, an output module 2, a positioning grinding frame 3, and a positioning mechanism 4, wherein the positioning grinding frame 3 is fixedly installed between the input module 1 and the output module 2. The positioning grinding frame 3 has positioning grooves 36 machined on both sides. The positioning mechanism 4 includes a moving shell 42. The moving shell 42 has a sliding key 421 on its side. The moving shell 42 is slidably assembled in the positioning groove 36 through the sliding key 421. The upper part of the moving shell 42 has a front and rear moving groove 422. The positioning grinding claw 41 is assembled in the front and rear moving groove 422. The bottom of the positioning grinding claw 41 has a support column 411. The bottom of the support column 411 has a limit hole 412. The bottom side of the moving shell 42 has a front and rear moving hole 423. The front and rear moving motor 43 is assembled in the front and rear moving hole 423. The motor shaft of the front and rear moving motor 43 passes through the front and rear moving hole 423 and the limit hole 412 in sequence. The bottom of the moving shell 42 has a positioning hole 424. The positioning rod 442 of the positioning motor 44 is assembled therein. At least two pressure sensors 413 are fixedly assembled in the positioning grinding claw 41. The positioning grinding claw 41 has evenly distributed grinding particles 45. The positioning motor 44 is fixedly mounted on the mounting plate 35 of the positioning grinding frame 3 via the mounting plate 441.

[0043] First, the positioning grinding frame 3 is a stable platform designed for various grinding operations. Positioning grooves 36 are machined on both sides of the grinding frame. These grooves primarily guide the movement of the sliding key 421 and the moving shell 42, ensuring their accurate positioning. In this way, the grinding frame provides a stable platform for grinding operations while guaranteeing positional accuracy during the grinding process. Next is the moving shell 42, a movable mechanism with sliding keys 421 on its sides, which can slide within the positioning grooves 36. The main function of the moving shell 42 is to support and protect the internal grinding claws and other accessories. Its design provides sufficient strength and stability to ensure precise positioning during grinding. Simultaneously, the sliding key 421 allows the moving shell 42 to slide freely within the positioning grooves 36, achieving a high degree of flexibility. The upper part of the moving shell 42 has front and rear movement grooves 422, providing space for the positioning grinding claws 41 to move back and forth. This design allows the grinding claws to move back and forth as needed, better adapting to different grinding requirements. The front and rear movement grooves 422 also facilitate the installation and adjustment of the grinding claws. The positioning grinding claw 41 is another important component. It is installed in the front and rear motion slots and can move back and forth. A support column 411 is provided at its bottom to support and stabilize the grinding claw. The design of the support column 411 ensures the stability and accuracy of the grinding claw during movement. Simultaneously, the design of the grinding claw also takes into account the installation of the pressure sensor 413, which can better monitor pressure changes during positioning and grinding. The support column 411 has a limiting hole 412 machined at its bottom, in which a front and rear motion motor 43 is installed, allowing the positioning grinding claw 41 to move back and forth. The side bottom of the motion housing 42 has front and rear motion holes 423 machined. These holes are used to install the front and rear motion motors 43, enabling the grinding claw to move back and forth. The installation of the front and rear motion motors 43 allows the grinding claw to move easily back and forth, thus better adapting to different grinding needs. At the same time, the installation of the motors also facilitates the electrically driven movement of the grinding claw. The design of the positioning hole 424 means that the bottom of the motion housing 42 has a positioning hole 424, which is used to guide the positioning rod 442 of the positioning motor 44. This design ensures that the positioning motor 44 can accurately drive the movement of the grinding claw. Simultaneously, the design of the positioning hole 424 facilitates the installation and adjustment of the positioning motor 44. Finally, there is the positioning motor 44, the pressure sensor 413, and the evenly distributed grinding particles 45. The positioning motor 44 is a drive mechanism whose positioning rod 442 is fitted into the positioning hole 424, providing positioning and drive for the grinding claw. This design allows the motor to precisely control the movement of the grinding claw, thereby ensuring the stability and accuracy of the grinding and positioning process. At the same time, the motor design also considers energy saving and quiet operation to provide a better working environment. At least two pressure sensors 413 are fixed in the positioning grinding claw 41; they may be used to detect pressure changes during the grinding process.During the positioning process, the positioning of the substrate glass 6 on that side is considered complete only when all three pressure sensors 413 simultaneously sense the same pressure. If they do not sense pressure simultaneously or the pressure values ​​are different, it indicates that the positioning of that side of the substrate glass 6 is not complete. In this case, the positioning grinding claw 41 on that side will continue to move forward until all three pressure sensors 413 simultaneously sense the same pressure, indicating that the positioning of that side of the substrate glass 6 is complete. The evenly distributed grinders 45, mounted in the positioning grinding claws 41, are the components that directly participate in the grinding process. Their material and distribution may affect the grinding effect. The design of the grinders 45 takes into account grinding efficiency and effect. The evenly distributed design can better cover the grinding area and perform effective grinding. At the same time, the material selection of the grinders 45 also takes into account wear resistance and durability to ensure that they maintain excellent performance even after long-term use.

[0044] The grinder 45 is a concave cylinder with a diameter that gradually decreases from both ends to the middle. The middle part of the grinder 45 has a concave grinding surface 452, on which a grinding brush 451 is provided. Multiple grinders 45 are arranged side by side to grind the side of the substrate glass 6. The concave grinding surface 452 grinds the edge of the side of the substrate glass 6. Under the action of the front and rear motion motor 43, the positioning grinding claw 41 moves back and forth on the side of the substrate glass 6, which can quickly complete the grinding of the side of the substrate glass 6.

[0045] The roller 374 is equipped with a hub motor 375, which is fixedly connected to the inside of the roller 374. The hub motor 375 enables the spring roller 37 to rotate. During the rotation, the substrate glass 6 placed on it can move forward after processing, so that the substrate glass 6 can smoothly enter the output module 2 from the positioning grinding frame 3.

[0046] Gears are mounted on the top of each grinder 45. The grinders 45 are interconnected by a chain 46. At least one grinder 45 is the driving grinder, and the rest are driven grinders. The gears on the top of each grinder 45 are used to transmit power. The gear design allows the grinder 45 to generate greater force during rotation, thus grinding the material more effectively. Simultaneously, the gear design ensures smooth operation of the grinder 45, reducing vibration and noise during the grinding process. The interconnection of the grinders 45 by the chain 46 allows all grinders 45 to rotate simultaneously and at the same speed. This design ensures uniformity in the grinding process, allowing all grinders 45 to function fully and improving grinding efficiency. The chain 46 also facilitates the installation and removal of the grinders 45, making maintenance and replacement simpler. At least one grinder 45 is the driving grinder, and the rest are driven grinders. The driving grinder is one that can rotate independently, while the driven grinders are those driven by the driving grinder. This design allows for better control of the grinding process, ensuring that all grinders 45 operate according to a predetermined pattern, resulting in superior grinding performance. Simultaneously, the driven grinder design makes the entire grinding system more energy-efficient, reducing unnecessary energy waste.

[0047] The positioning grinding frame 3 has evenly distributed airflow disc mounting holes 31, in which airflow discs 39 are installed. The airflow discs 39 can draw in and blow air. A large suction cup mounting hole 33 is machined at the center of the positioning grinding frame 3, in which a rotating lifting mechanism 5 is installed. Roller grooves 32 are machined at the intervals of the airflow disc mounting holes 31, in which spring rollers 37 are installed. Connecting holes 34 are machined on both sides of the large suction cup mounting holes 33, in which connecting wheels 38 are installed. The positioning grinding frame 3 has evenly distributed airflow disc mounting holes 31 for mounting the airflow discs 39. The airflow disk 39 blows air when the substrate glass 6 enters the positioning grinding frame 3. Due to the weight of the substrate glass 66, the spring roller 37 is compressed immediately upon entering the positioning grinding frame 3, causing the substrate glass 66 to contact the top of the airflow disk 39 and preventing its forward movement. At this time, the airflow disk 39 blows air upward, creating an isolation layer between the substrate glass 66 and the airflow disk 39, ensuring the substrate glass 66 moves forward smoothly. The airflow disk 39's suction increases the adhesion between the grinding frame and the working surface, providing better stability during operation. Simultaneously, the evenly distributed design allows the airflow disk 39 to better cover the working area, ensuring uniform adhesion and accurate positioning. The airflow disks 39 are fitted into the airflow disk mounting holes 31. These airflow disks 39 have strong adhesion and can firmly adhere to the working surface. The design of the airflow disks 39 improves the stability of the grinding frame, making the grinding and positioning process more precise and stable. A large suction cup mounting hole 33 is machined in the center of the positioning grinding frame 3 for mounting the rotary lifting mechanism 5. The design of the rotary lifting mechanism 5 allows the substrate glass 6, whose two sides have been ground, to be rotated 90° under the action of the rotary lifting mechanism 5, and then the remaining two unground sides are positioned and ground. Roller grooves 32 are machined at the intervals of the airflow disk mounting holes 31, and spring rollers 37 are installed in these roller grooves 32. The design of the spring rollers 37 provides a certain degree of elasticity and cushioning. That is, when the substrate glass 6 first enters the positioning grinding frame 3, in order to prevent the suction cup from affecting the forward path of the substrate glass 6 and increasing its forward resistance, the rollers 374, which are higher than the suction cup, can provide a good medium for the forward movement of the substrate glass 6. After the substrate glass 6 is fully inside the positioning grinding frame 3, due to the weight of the substrate glass 6 itself, the large compression spring 372 and the connecting spring 383 are compressed, making the bottom of the substrate glass 6 close to the top of the airflow disk 39 and the large suction cup 51, which is more conducive to the adsorption of the airflow disk 39 and the large suction cup 51. Connecting holes 34 are machined on both sides of the large suction cup mounting hole 33, and connecting wheels 38 are assembled in these connecting holes 34.The design of the connecting roller 38 allows the substrate glass 6, which is not long enough to cross the two spring rollers 37 at once, to be supported by the connecting roller 381 in the middle. This allows the substrate glass 6, which is not long enough, to be positioned and ground on the device, and then transported out from the positioning and grinding frame 3 after the grinding is completed.

[0048] The spring roller 37 includes a limiting post 371, a large compression spring 372, a lifting post 373, and a roller 374. The limiting post 371 is fixedly installed at the bottom of the roller groove 32, the large compression spring 372 is assembled therein, the lifting post 373 is inserted through the limiting post 371, and the roller 374 is rotatably assembled between the two lifting posts 373. A hub motor 375 is installed inside the roller 374. The design of the spring roller 37 provides a certain degree of elasticity and cushioning. That is, when the substrate glass 6 just enters the positioning grinding frame 3, in order to prevent the suction cup from affecting the forward path of the substrate glass 6 and increasing its forward resistance, the roller 374, which is higher than the suction cup, can provide a good medium for the forward movement of the substrate glass 6. After the substrate glass 6 has completely entered the positioning grinding frame 3, due to the weight of the substrate glass 6 itself, the large compression spring 372 and the connecting spring 383 are compressed, so that the bottom of the substrate glass 6 is close to the top of the airflow disk 39 and the large suction cup 51, which is more conducive to the adsorption of the airflow disk 39 and the large suction cup 51. Furthermore, the hub motor 375 installed therein can feed the ground substrate glass 6 into the output module 2, ensuring the smooth output of the substrate glass 6.

[0049] The connecting wheel 38 includes a mounting post 384, a connecting roller 381, a connecting post 382, ​​and a connecting spring 383. The mounting post 384 is fixedly installed at the center of the bottom of the connecting hole 34, and the connecting spring 383 is assembled therein. The connecting post 382 is inserted into the mounting post 384, and the connecting roller 381 is rotatably mounted on the connecting post 382. The design of the connecting wheel 38 allows for the positioning and grinding of substrate glass 6 that is too short to cross two spring rollers 37 in one go, with the connecting roller 381 providing support in the middle. The connecting spring 383 serves the same function as the large compression spring 372.

[0050] The top height of rollers 374 and connecting rollers 381 is higher than the top height of airflow disk 39. When the substrate glass 6 just enters the positioning grinding frame 3, in order to prevent the suction cup from affecting the forward path of the substrate glass 6 and increasing its forward resistance, rollers 374 and connecting rollers 381, which are higher than the suction cup, can provide a good medium for the forward movement of the substrate glass 6, that is, reduce the contact between the substrate glass 6 and the suction cup and reduce the forward friction.

[0051] The rotary lifting mechanism 5 includes a large suction cup 51, a lifting motor 52, and a rotary motor 53. The bottom of the large suction cup 51 is fixedly connected to the motor shaft of the lifting motor 52. A bevel gear is provided at the bottom of the lifting motor 52. The rotary motor 53 is connected to the lifting motor 52 through the bevel gear. The rotary motor 53 is fixedly installed at the bottom of the positioning grinding frame 3. As part of the rotary lifting mechanism 5, the bottom of the large suction cup 51 is fixedly connected to the motor shaft of the lifting motor 52. The design of the large suction cup 51 provides strong suction force, thus firmly adhering to the back of the substrate glass 6. This not only ensures that the position of the substrate glass 6 remains unchanged during grinding but also fixes the substrate glass 6 during lifting and rotation. The lifting motor 52 is the core component of the rotary lifting mechanism 5, and its motor shaft is fixedly connected to the bottom of the large suction cup 51. The design of the lifting motor 52 allows the large suction cup 51 to move up and down through the power transmission of the motor shaft. This design allows the large suction cup 51 to be vertically adjusted as needed, so that the substrate glass 6 can be lifted upwards and then rotated. The bottom of the lifting motor 52 is equipped with a bevel gear, which has unique transmission characteristics and can achieve high torque and high precision power transmission. The bevel gear design ensures accurate matching and power transmission between the lifting motor 52 and the rotary motor 53, thereby enabling the entire rotary lifting mechanism 5 to operate in a coordinated manner. The rotary motor 53 is connected to the lifting motor 52 through the bevel gear and is fixedly installed at the bottom of the positioning and grinding frame 3. The rotary motor 53 is designed to drive the large suction cup 51 of the adsorption substrate glass 6 to rotate, causing the substrate glass 6 to rotate 90° and then be lowered, so that the two un-grinded sides can be positioned and ground.

[0052] Working principle: When the substrate glass 6 to be ground is transported from the input module 1 to the positioning grinding frame 3, since the top height of the roller 374 and the connecting roller 381 is higher than the top height of the airflow disk 39, the substrate glass 6 entering the positioning grinding frame 3 from the input module 1 will continue to move forward under the action of the roller 374. When the substrate glass 6 is completely inside the positioning grinding frame 3, the hub motor 375 in the roller 374 will stop, and the positioning mechanism 4 will then position the substrate glass 6. One of the positioning grinding claws 41 on both sides will first move towards the middle under the action of the positioning motor 44. When the pressure sensor 413 simultaneously contacts the side of the substrate glass 6, it indicates that the positioning of this side of the substrate glass 6 is complete. If several pressure sensors 413 do not simultaneously contact the side of the substrate glass 6, it indicates that the positioning of this side of the substrate glass 6 is not complete, that is, the side of the substrate glass 6 is in an inclined state, and the positioning grinding claw 41 on this side needs to continue to move forward until the pressure sensor 413 simultaneously contacts the side of the substrate glass 6, indicating that the positioning is complete. At this time, the positioning grinding claw 41 on the other side will also move towards the center. When several pressure sensors 413 on the positioning grinding claw 41 on the other side simultaneously contact the other side of the substrate glass 6, it indicates that the positioning is complete, that is, the positioning of the substrate glass 6 in the front-back direction is completed. At this time, the airflow disk 39 on the positioning grinding frame 3 will adsorb the substrate glass 6. After adsorption is complete, the grinder 45 on the positioning grinding claw 41 will grind the two corresponding sides of the substrate glass 6, and move back and forth under the action of the front-back motion motor 43 to ensure thorough grinding. After the two sides of the substrate glass 6 are ground, the large suction cup 51 adsorbs the substrate glass 6, the airflow disk 39 releases the adsorption of the substrate glass 6, the lifting motor 52 starts to operate, lifting the substrate glass 6 to a certain height, and then the rotation motor 53 starts to operate, so that the substrate glass 6 rotates 90° and is put back in its original position, and then repositioning is performed. Finally, the two ends that have not been ground are ground.
