An automatic positioning mechanism with a mechanical arm and a numerical control system as cores is presented. The automatic positioning mechanism can realize high-precision and high-efficiency grinding processing through a high-precision sensor and a control system. In recent years, with the rapid development of technologies such as artificial intelligence and machine learning, the positioning mechanism of the substrate glass grinder is also being upgraded. Intelligent positioning mechanisms based on machine vision and deep learning are emerging.

(III) beneficial effects
Compared with the prior art, the invention provides a positioning mechanism of a substrate glass grinder, which has the following beneficial effects:
1. the positioning mechanism of the substrate glass grinder is matched with the positioning grinding frame for use. When the substrate glass to be ground is conveyed to the positioning grinding frame by the input module, the substrate glass entering the positioning grinding frame from the input module can move forwards under the action of the roller because the top heights of the roller and the connecting roller are higher than the top height of the air flow disc, and when the substrate glass completely enters the positioning grinding frame, the hub motor in the roller can stop, and the positioning mechanism can position the substrate glass. One positioning grinding claw of the positioning grinding claws at two sides moves towards the middle under the action of the positioning motor, after the pressure sensors are simultaneously contacted with the side edge of the substrate glass, the positioning of the substrate glass at the side is finished, if the pressure sensors are not simultaneously contacted with the side edge of the substrate glass, the positioning of the substrate glass at the side is not finished, namely the side edge of the substrate glass is in an inclined state, the positioning grinding claw at the side needs to move forwards continuously until the pressure sensors are not simultaneously contacted with the side edge of the substrate glass, and the positioning is finished. At this time, the positioning grinding claw at the other side is also closed towards the center, and after the pressure sensors on the positioning grinding claw at the other side are simultaneously contacted with the other side of the substrate glass, the positioning is finished, namely the positioning of the substrate glass in the front-rear direction is finished. At this time, the airflow disc on the positioning grinding frame can adsorb the substrate glass, and after adsorption is completed, the grinder on the positioning grinding claw grinds two corresponding sides of the substrate glass, and moves back and forth under the action of the back and forth motor, so that the grinding is ensured to be full. After the two sides of the substrate glass are polished, the large sucker adsorbs the substrate glass, the air flow disc loosens the adsorption to the substrate glass, the lifting motor starts to operate at the moment, the substrate glass is lifted to a certain height, then the rotating motor starts to operate, the substrate glass is placed back to the original position after rotating by 90 degrees, then the positioning is carried out again, and finally the two ends which are not polished are polished. Therefore, the edges of two pieces of substrate glass are positioned at one time, the influence factors of the number of positioning edges are reduced, fewer variables are controlled, and the positioning accuracy is improved.
2. The positioning mechanism of the substrate glass grinder is matched with the positioning grinding frame for use. The plurality of grinders are arranged in parallel to grind the side edges of the substrate glass, the concave grinding faces grind the edges of the side edges of the substrate glass, and the positioning grinding claw moves back and forth on the side edges of the substrate glass under the action of the back and forth motor, so that the side edges of the substrate glass can be quickly ground. Therefore, the effect of saving time by simultaneously grinding a plurality of grinders is achieved.
3. The positioning mechanism of the substrate glass grinder is matched with the positioning grinding frame for use. When the substrate glass enters the positioning grinding frame, the weight exists on the substrate glass, the spring roller is pressed downwards by the weight of the substrate glass, the lower surface of the substrate glass is contacted with the upper end of the air flow disc, the substrate glass is difficult to move forwards, the air flow disc blows upwards, the substrate glass and the upper end of the air flow disc keep a certain distance all the time, and the substrate glass can move forwards smoothly. After the substrate glass is processed, the air flow disc continues to blow upwards, and then the hub motor starts to operate, so that the substrate glass smoothly enters the output module from the positioning grinding frame. Thereby achieving the effect of one-time completion of feeding, grinding and discharging and simple operation.
4. The positioning mechanism of the substrate glass grinder is matched with the positioning grinding frame for use. In addition, the single-side positioning mode can prevent the two opposite angles of the substrate glass from being clamped by the double-side positioning mechanism due to the simultaneous positioning of the two sides in the positioning process of the substrate glass, so that the substrate glass is damaged. Therefore, the effects that the substrate glass is extruded and damaged by the positioning mechanism can be achieved after single-side positioning and then double-side positioning.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-13, a positioning mechanism of a substrate glass grinder 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 is provided with positioning grooves 36 on two sides, the positioning mechanism 4 comprises a moving shell 42, sliding clamping keys 421 are arranged on the side edges of the moving shell 42, the moving shell 42 is slidably assembled in the positioning grooves 36 through the sliding clamping keys 421, front-back moving grooves 422 are formed in the upper portion of the moving shell 42, positioning grinding claws 41 are assembled in the front-back moving grooves 422, supporting columns 411 are arranged at the bottoms of the positioning grinding claws 41, limiting holes 412 are formed in the bottoms of the supporting columns 411, front-back moving holes 423 are formed in the bottoms of the side edges of the moving shell 42, front-back moving motors 43 are assembled in the front-back moving holes 423, motor shafts of the front-back moving motors 43 sequentially penetrate through the front-back moving holes 423 and the limiting holes 412, positioning holes 424 are formed in the bottoms of the moving shell 42, positioning rods 442 of the positioning motors 44 are assembled in the positioning grinding claws 41, at least two pressure sensors 413 are fixedly assembled in the positioning grinding claws 41, and evenly distributed grinders 45 are assembled in the positioning grinding claws 41. The positioning motor 44 is fixedly mounted on the mounting plate 35 of the positioning grinding frame 3 by the mounting plate 441.
First, the positioning frame 3 is a stable platform designed for various grinding operations. Positioning grooves 36 are formed on both sides of the grinding frame, and the grooves mainly serve to guide the movement of the sliding clamping key 421 and the movement shell 42, so that the position accuracy of the sliding clamping key and the movement shell is ensured. In this way, the grinding frame can provide a stable platform for the grinding operation, while ensuring the positional accuracy of the grinding process. Next is a movable housing 42, which is provided with sliding catches 421 on its sides, which can be slid into the positioning slots 36. The main function of the motion housing 42 is to carry and protect the internal grinding claws and other accessories. Its design is strong and stable enough to ensure that the precise position is maintained during the grinding process. Meanwhile, by the design of the sliding catch 421, the moving housing 42 can freely slide in the positioning groove 36, achieving a high degree of flexibility. The upper portion of the moving case 42 is formed with a back and forth moving groove 422 in order to provide a space for the front and back movement of the positioning grinding claw 41. The design enables the grinding claw to move back and forth according to actual needs, so that different grinding requirements can be well met. At the same time, the design of the back and forth movement slots 422 also facilitates the installation and adjustment of the grinding claws. Positioning the grinding claw 41 is another important component, and it is installed in the front-rear movement groove to perform the front-rear movement. The bottom of which is provided with a support column 411 for supporting and stabilizing the grinding claw. The design of the support column 411 ensures stability and accuracy of the grinding claw during movement. At the same time, the design of the grinding claw also allows for the installation of the pressure sensor 413, which allows for better monitoring of pressure changes during positioning and grinding. The support column 411 having a limit hole 412 formed in the bottom thereof is provided with the back and forth movement motor 43 mounted in the limit hole 412, so that the positioning grinding claw 41 can be moved back and forth. The side bottoms of the moving case 42 are formed with back and forth moving holes 423 for assembling the back and forth moving motor 43 so that the grinding claws can be moved back and forth. The mounting of the back and forth motor 43 allows the grinding claw to be easily moved back and forth to better accommodate different grinding requirements. Meanwhile, the motor is convenient to install, and the grinding claw is driven to move through electric power. The positioning hole 424 is designed such that the bottom of the moving case 42 is formed with the positioning hole 424, which is a positioning rod 442 for guiding the positioning motor 44. This design ensures that the positioning motor 44 can accurately drive the movement of the grinding claw. At the same time, the design of the positioning hole 424 also facilitates the installation and adjustment of the positioning motor 44. Finally, the motor 44 and the pressure sensor 413 are positioned and the grinder 45 is uniformly distributed. The positioning motor 44 is a drive mechanism with a positioning rod 442 that fits into the positioning hole 424 to provide positioning and drive for the grinding claw. The design enables the motor to accurately control the movement of the grinding claw, thereby ensuring the stability and the precision of the grinding and positioning process. Meanwhile, the design of the motor also considers the energy saving and silencing performance so as to provide a better working environment. At least two pressure sensors 413 are fixed in the positioning grinding jaw 41, which may be used to detect pressure changes during the grinding process. In the positioning process, when three pressure sensors 413 simultaneously sense the same pressure, the positioning of the side substrate glass 6 is calculated. If the pressure is not sensed at the same time or the sensed pressures are different, the side edge of the substrate glass 6 is not positioned, and the positioning grinding claw 41 of the side edge continues to move forward until the three pressure sensors 413 sense the same pressure at the same time, which indicates that the positioning of the side edge of the substrate glass 6 is completed. The grinder 45 installed in the positioning grinding claw 41 and uniformly distributed is a component directly involved in grinding, and its material and distribution may affect the grinding effect. The grinder 45 is designed to better cover the grinding area and perform effective grinding by uniformly distributing the design in consideration of grinding efficiency and effect. At the same time, the choice of material for the grinder 45 also allows for wear resistance and durability to ensure that good performance is maintained over extended periods of use.
The grinder 45 is a middle concave cylinder with the diameters of both ends gradually reduced toward the middle, the middle part of the grinder 45 is a concave grinding surface 452, and the grinding brush 451 is arranged on the concave grinding surface 452. The plurality of grinders 45 are arranged together in parallel to grind the side edges of the substrate glass 6, the concave grinding surface 452 grinds the side edges of the substrate glass 6, and the positioning grinding claw 41 moves back and forth on the side edges of the substrate glass 6 under the action of the back and forth motor 43, so that the grinding of the side edges of the substrate glass 6 can be completed rapidly.
The inside of the roller 374 is equipped with a hub motor 375, and the outside of the hub motor 375 is fixedly connected with the inside of the roller 374. The hub motor 375 can rotate the spring roller 37, and in the process of rotation, the substrate glass 6 placed thereon can be moved forward after the processing is completed, so that the substrate glass 6 smoothly enters the output module 2 from the positioning grinding frame 3.
The top of the grinders 45 is provided with gears, the grinders 45 are connected with each other through a chain 46, at least one driving grinder is arranged in the grinders 45, and the rest grinders 45 are driven grinders. The top of the grinder 45 is provided with gears which may be used to transmit power. By the design of the gears, the grinder 45 can be made to generate more force when rotating, thereby grinding the material better. Meanwhile, the design of the gears can ensure the smooth running of the grinder 45 and reduce vibration and noise in the grinding process. The grinders 45 are interconnected by a chain 46 which allows all of the grinders 45 to be rotated simultaneously and at the same rotational speed. This design ensures uniformity of the grinding process so that all grinders 45 can function adequately to improve grinding efficiency. At the same time, the design of the chain 46 also facilitates the mounting and dismounting of the grinder 45, so that maintenance and replacement of the grinder 45 becomes simpler. At least one of the grinders 45 is a driving grinder, and the other grinders 45 are driven grinders. The driving grinder refers to a grinder 45 capable of rotating autonomously, and the driven grinder is a grinder 45 driven by the driving grinder.

Wherein the engagement spring 383 functions in the same manner as the large compression spring 372.
The top height of roller 374 and engagement roller 381 is higher than the top height of air flow tray 39. When the substrate glass 6 just enters the positioning grinding frame 3, in order to prevent the sucking disc from influencing the advancing route of the substrate glass 6 and increasing the advancing resistance of the substrate glass, the roller 374 and the engagement roller 381 which are higher than the sucking disc can provide a good medium for the advancing of the substrate glass 6, namely, reduce the contact between the substrate glass 6 and the sucking disc and reduce the advancing friction force.
The rotary lifting mechanism 5 comprises a large sucker 51, a lifting motor 52 and a rotary motor 53, wherein the bottom of the large sucker 51 is fixedly connected with a motor shaft of the lifting motor 52, a conical gear is arranged at the bottom of the lifting motor 52, the rotary motor 53 is mutually matched and connected with the lifting motor 52 through the conical gear, and the rotary motor 53 is fixedly arranged at the bottom of the positioning grinding frame 3. As a part of the rotary lifting mechanism 5, the bottom of the large suction cup 51 is fixedly connected with the motor shaft of the lifting motor 52.

The bottom of the lifting motor 52 is provided with a bevel gear which has unique transmission characteristics and can realize high torque and high precision power transmission. The design of the bevel gear ensures an accurate fit and power transfer between the lifting motor 52 and the rotary motor 53, enabling a coordinated operation of the entire rotary lifting mechanism 5. The rotating motor 53 is mutually matched and connected with the lifting motor 52 through a bevel gear, and is fixedly arranged at the bottom of the positioning grinding frame 3. The rotary motor 53 is designed to drive the large suction cup 51 sucking the substrate glass 6 to perform a rotary motion so that the substrate glass 6 is rotated by 90 ° and then put down, and then the both sides without grinding are positioned and ground.
Working principle is that when the substrate glass 6 to be ground is conveyed onto the positioning grinding frame 3 by the input module 1, the substrate glass 6 entering the positioning grinding frame 3 from the input module 1 moves forward under the action of the roller 374 because the top heights of the roller 374 and the engagement roller 381 are higher than the top height of the air flow disc 39, and when the substrate glass 6 completely enters the positioning grinding frame 3, the hub motor 375 in the roller 374 stops, and the positioning mechanism 4 positions the substrate glass 6. One positioning grinding claw 41 of the positioning grinding claws 41 on two sides moves towards the middle under the action of the positioning motor 44, after the pressure sensors 413 are simultaneously contacted with the side edge of the substrate glass 6, the positioning of the substrate glass 6 on the side is finished, if the pressure sensors 413 are not simultaneously contacted with the side edge of the substrate glass 6, the positioning of the substrate glass 6 on the side is not finished, namely, the side edge of the substrate glass 6 is in an inclined state, and the positioning grinding claw 41 on the side needs to move forwards continuously until the pressure sensors 413 are simultaneously contacted with the side edge of the substrate glass 6, so that the positioning is finished. At this time, the positioning grinding claw 41 on the other side will also be close to the center, and after the pressure sensors 413 on the positioning grinding claw 41 on the other side contact the other side of the substrate glass 6 at the same time, the positioning is completed, that is, the positioning of the substrate glass 6 in the front-rear direction is completed. At this time, the air flow disc 39 on the positioning grinding frame 3 will adsorb the substrate glass 6, and after the adsorption is completed, the grinder 45 on the positioning grinding claw 41 will grind two corresponding sides of the substrate glass 6, and move back and forth under the action of the back and forth motor 43, so as to ensure sufficient grinding. After the two sides of the substrate glass 6 are polished, the large sucking disc 51 adsorbs the substrate glass 6, the air flow disc 39 releases the adsorption of the substrate glass 6, at this time, the lifting motor 52 starts to operate to lift the substrate glass 6 by a certain height, then the rotating motor 53 starts to operate, so that the substrate glass 6 is put back to the original position after rotating by 90 degrees, then the positioning is performed again, and finally the two ends which are not polished are polished.
