Description

Technical Field

[0001] The invention relates to the technical field of glass processing, and in particular to a glass side grinding device for glass production, which can avoid grinding deviation. Background Art

[0002] Laminated glass uses a transparent, adhesive plastic film between two or three layers of glass, combining the toughness of the plastic with the hardness of the glass to increase its resistance to shattering. Tempered glass is ordinary glass that has been tempered to create a certain amount of internal stress within the structure, thereby increasing its strength. When shattered by impact, the glass breaks into small, blunt-edged fragments, causing less damage.

[0003] Car windshields are now adopting single-piece curved windshields, gradually abandoning flat windshields. Today's car windshields are generally made into a single, large, curved surface, with a certain curvature in the top, bottom, left, and right directions. This type of curved glass requires extremely high technical requirements, both in terms of processing and assembly, as it involves many issues, including vehicle type, strength, thermal insulation, and assembly.

[0004] After the glass is produced, it needs to be polished to remove burrs, etc. However, glass comes in many shapes. It is easier to polish the edges of rectangular glass, but it is more troublesome to polish round glass. It is usually placed on a turntable and rotated for polishing. However, the turntable and the center of the round glass are not in the same position, which can easily cause the thickness of the edge to be uneven, thus making the product unqualified. At the same time, when the disk rotates, the glass can easily be offset.

[0005] Especially for the irregular and curved glass of the car's front windshield, different polishing degrees are prone to occur during the polishing process, resulting in insufficient smoothness of the curved glass and unstable polished shape, making it difficult to effectively fit the frame shape and ensure the sealing effect.

[0006] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] As introduced in the background technology, in order to solve the deficiencies in the prior art and the above technical problems, the present application proposes a glass side grinding device for glass production that avoids grinding deviation.

[0035] See also Figures 1-10A glass side grinding device for glass production that avoids grinding deviation includes: a conveying mechanism 1, a positioning mechanism 2, a gripping mechanism 3 and a lifting and leveling mechanism 4; after the curved glass is placed on the conveying mechanism 1, the conveying mechanism 1 guides the curved glass to slide under the action of gravity, and limits the curved glass to the central position of the conveying mechanism 1. The conveying mechanism 1 is also used to drive the curved glass to enter and exit the glass side grinding device; the positioning mechanism 2 is used to cooperate with the conveying mechanism 1 to limit the curved glass to be directly below the gripping mechanism 3; the gripping mechanism 3 includes a plurality of vacuum suction cups 31, and the lifting and leveling mechanism 4 can simultaneously control all the vacuum suction cups 31 to rise synchronously The lifting and leveling mechanism 4 can also control the lifting and lowering of each vacuum suction cup 31 to level the curved glass; the glass side grinding device also includes at least two grinding mechanisms, each grinding mechanism includes a distance limiting mechanism 5, an angle calibration mechanism 6 and a grinding unit 7; after the curved glass is leveled and raised to the grinding position, inside each grinding mechanism, the distance limiting mechanism 5 is used to keep the distance between the grinding unit 7 and the side of the curved glass constant, and the angle calibration mechanism 6 is used to keep the grinding unit 7 perpendicular to the angle of the side of the curved glass. While keeping the grinding unit 7 perpendicular to the side of the curved glass, it evenly grinds the side of the curved glass.

[0036] When in use, the curved glass (car front windshield) after preliminary cutting and forming is placed on the conveying mechanism 1, and the conveying mechanism 1 guides the curved glass to slide under the action of gravity, and limits the curved glass to the central position of the conveying mechanism 1. The conveying mechanism 1 first drives the curved glass to be input into the glass side grinding device, and then the positioning mechanism 2 cooperates with the conveying mechanism 1 to limit the curved glass to be directly below the grasping mechanism 3, so as to effectively ensure that each vacuum suction cup 31 of the grasping mechanism 3 can accurately grasp the positioned curved glass. The lifting and leveling mechanism 4 first drives all the vacuum suction cups 31 to descend synchronously, so that each vacuum suction cup 31 is close to the curved glass, and then the lifting and leveling mechanism 4 drives each vacuum suction cup 31 to perform fine adjustment, so that each vacuum suction cup 31 conforms to the shape of the curved glass. The balance of the curved glass can be ensured by fine adjustment of each vacuum suction cup 31 (that is, the curved glass is leveled), and then The lifting and leveling mechanism 4 simultaneously drives each vacuum suction cup 31 to rise synchronously until the curved glass is raised to the grinding position, and then the distance limiting mechanism 5 of the two grinding mechanisms keeps the distance between the grinding unit 7 and the side of the curved glass constant, so as to effectively limit the grinding thickness of the grinding unit 7 and avoid the problem of uneven grinding degree. The angle calibration mechanism 6 keeps the grinding unit 7 perpendicular to the angle of the side of the curved glass. While the grinding unit 7 keeps perpendicular to the side of the curved glass, it ensures the grinding accuracy and the shape of each grinding position through vertical limitation, so as to be able to effectively and fully grind the curved glass evenly, ensure the grinding accuracy of the curved glass, and ensure that the distance limiting mechanism 5 and the angle calibration mechanism 6 are used to match curved glasses with different curvatures, and make the grinding shape and grinding thickness of curved glasses with different curvatures consistent, so as to effectively ensure the grinding effect of the curved glass.

[0037] Further, see Figures 6-10 The distance limiting mechanism 5 includes a positioning roller 51, a limiting roller 52 and a limiting mounting plate 53; a limiting rotating shaft 531 is provided at the bottom end of the limiting mounting plate 53, and the limiting rotating shaft 531 is rotatably connected to a positioning rod 532 and a limiting rod 533, and the end of the positioning rod 532 away from the limiting rotating shaft 531 is connected and fixed to the positioning roller 51, and the end of the limiting rod 533 away from the limiting rotating shaft 531 is connected and fixed to the limiting roller 52.

[0038] A limiting spring 534 is provided at one end of the positioning rod 532 and the limiting rod 533 close to the limiting shaft 531. The limiting spring 534 is used to provide elastic force to drive the positioning rod 532 and the limiting rod 533 to have a tendency to approach each other; under the elastic force limitation of the limiting spring 534, the positioning roller 51 can move on the curved surface of the curved glass, the limiting roller 52 can move on the side of the curved glass, and the distance between the limiting mounting plate 53 and the positioning roller 51 remains constant.

[0039] Therefore, when in use, the angle between the positioning rod 532 and the limiting rod 533 is limited by the elastic force of the limiting spring 534 to ensure that the positioning roller 51 can move closely against the curved surface of the curved glass, and the limiting roller 52 can move closely against the side of the curved glass. The positioning rod 532 is connected and fixed to the positioning roller 51, and the limiting rod 533 is connected and fixed to the limiting roller 52 to keep the distance between the limiting mounting plate 53 and the positioning roller 51 constant, so as to ensure that the distance between the grinding unit 7 and the side of the curved glass is constant and vertical, thereby effectively limiting the grinding thickness of the grinding unit 7 and avoiding the problem of uneven grinding degree.

[0040] Further, see Figures 6-10 The angle calibration mechanism 6 includes a reference plate 61, which is rotatably connected to the limit mounting plate 53, and the grinding unit 7 is installed on one side of the reference plate 61; the angle calibration mechanism 6 includes two calibration pulleys 62 and a guide member 63, and the two calibration pulleys 62 are respectively arranged on both sides of the guide member 63, and the guide member 63 and the calibration pulley 62 are both connected and fixed by a calibration spring 64.

[0041] The guide member 63 includes a swing rod 631, one end of which is fixed to the reference plate 61, and a telescopic guide rod 632 is symmetrically arranged on the side of the swing rod 631 away from the reference plate 61. The movable ends of the telescopic guide rod 632 are respectively fixed to the calibration pulley 62, and the calibration springs 64 are respectively mounted on the outside of the telescopic guide rod 632.

[0042] Under the elastic force of the calibration spring 64, the two calibration pulleys 62 can move respectively on the two curved surfaces of the curved glass. The telescopic guide rod 632 is maintained in the center of the two calibration pulleys 62 by the opposite elastic forces of the two calibration springs 64 and is in a vertical position on the connecting line of the two calibration pulleys 62.

[0043] Therefore, when in use, under the elastic force of the calibration spring 64, the calibration pulley 62 can move on the two curved surfaces of the curved glass respectively, and the telescopic guide rod 632 is maintained in the center of the two calibration pulleys 62 by the elastic forces of the two calibration springs 64 in opposite directions, and is in a vertical position of the connection line of the two calibration pulleys 62, ensuring the angle between the swing rod 631 and the side of the curved glass, so that through the vertical limitation, the grinding accuracy and the shape of each grinding position are guaranteed, so that the curved glass can be effectively and fully ground evenly.

[0044] Further, see Figures 6-10The grinding unit 7 includes a grinding drive motor 71, a torsion spring 72 and a grinding head 73. The output shaft of the grinding drive motor 71 is fixed between the torsion spring 72 and the grinding head 73. Each grinding mechanism also includes a driving mechanical arm 8. The movable end of the driving mechanical arm 8 is fixed between the limit mounting plate 53. The driving mechanical arm 8 moves by driving the limit mounting plate 53, driving the grinding head 73 to move along the side of the curved glass. At the same time, through the action of the torsion spring 72, the grinding head 73 can be fully pressed against the side of the curved glass, effectively ensuring the grinding effect.

[0045] Further, see Figure 2-Figure 5 The conveying mechanism 1 includes a supporting member 11 and a linear driving mechanism 12. The linear driving mechanism 12 can drive the supporting member 11 to move; a central supporting member 111 and a plurality of symmetrically arranged telescopic support rods 112 are provided on the upper surface of the supporting member 11. The telescopic support rods 112 can be extended and retracted along with the curved glass. A driving roller 113 is also provided at the top of the telescopic support rod 112. The driving rollers 113 at the top of the two symmetrically arranged telescopic support rods 112 rotate in opposite directions, driving the curved glass to move toward the central position of the conveying mechanism 1.

[0046] The positioning mechanism 2 includes two positioning components 21, and the two positioning components 21 are respectively arranged on both sides of the central support member 111 along the supporting member 11; the positioning components 21 each include an electric lifting rod 211 and a movable push plate 212, and the electric lifting rod 211 can drive the movable push plate 212 to rise and fall; after the curved glass moves to the central position of the conveying mechanism 1, the movable push plate 212 is lifted by the electric lifting rod 211, and the two movable push plates 212 can approach each other to confine the curved glass directly below the grasping mechanism 3.

[0047] Thus, by extending and retracting each telescopic support rod 112, the curvature of the curved glass can be adapted. At the same time, the driving roller 113 is also arranged at the top of the telescopic support rod 112. The driving rollers 113 at the top of the two telescopic support rods 112 arranged at symmetrical positions rotate in opposite directions, driving the curved glass to move toward the central position of the conveying mechanism 1, so as to gradually limit the curved glass to the central position of the conveying mechanism 1, and then the movable push plate 212 is raised by the electric lifting rod 211. The two movable push plates 212 approach each other to limit the curved glass to the bottom of the grabbing mechanism 3, so as to accurately match the position of the curved glass, avoid grinding deviation, and effectively ensure the effect of the later grinding.

[0048] Further, see Figure 1-Figure 2The lifting and leveling mechanism 4 includes a main lifting assembly 41 and several electric telescopic rods 42. The fixed ends of the several electric telescopic rods 42 are fixed to the movable end of the main lifting assembly 41. The movable end of each electric telescopic rod 42 is fixed between a vacuum suction cup 31, so that the fixed ends of each electric telescopic rod 42 can be controlled to move synchronously by the main lifting assembly 41 to drive each vacuum suction cup 31 to move synchronously, and then each vacuum suction cup 31 is driven by each electric telescopic rod 42 to perform fine-tuning so that each vacuum suction cup 31 conforms to the shape of the curved glass. The balance of the curved glass can be ensured by fine-tuning each vacuum suction cup 31, thereby ensuring the balance and stability of the curved glass in the polishing position and ensuring the accuracy of the later polishing.

[0049] Working principle: When in use, the curved glass (car windshield) after preliminary cutting and forming is placed on the conveying mechanism 1, and the telescopic support rod 112 can be extended and retracted with the curved glass under the action of the gravity of the curved glass. Then, the driving roller 113 is also arranged at the top of the telescopic support rod 112. The driving rollers 113 at the top of the two telescopic support rods 112 arranged in symmetrical positions rotate in opposite directions, driving the curved glass to move toward the central position of the conveying mechanism 1, so as to gradually restrict the curved glass to the central support member 111 at the central position of the conveying mechanism 1, and then the movable push plate 212 is lifted by the electric lifting rod 211, and the two movable push plates 212 approach each other to restrict the curved glass to the bottom of the grabbing mechanism 3, so as to accurately match the position of the curved glass, avoid grinding offset, and effectively ensure the effect of later grinding.

[0050] The lifting and leveling mechanism 4 controls the fixed ends of the electric telescopic rods 42 to move synchronously through the main lifting assembly 41, thereby driving the vacuum cups 31 to move synchronously. Then, each electric telescopic rod 42 drives each vacuum cup 31 to perform fine adjustments so that each vacuum cup 31 conforms to the shape of the curved glass. The fine adjustments of each vacuum cup 31 can ensure the balance of the curved glass, thereby ensuring the balance and stability of the curved glass in the polishing position and the accuracy of the subsequent polishing. Then, the lifting and leveling mechanism 4 drives each vacuum cup 31 to rise synchronously at the same time until the curved glass is raised to the polishing position.

[0051] During the grinding process, the elastic force of the limit spring 534 limits the angle between the positioning rod 532 and the limit rod 533 to ensure that the positioning roller 51 can move close to the curved surface of the curved glass, and the limit roller 52 can move close to the side of the curved glass. The distance between the limit mounting plate 53 and the positioning roller 51 is kept constant by connecting and fixing the positioning rod 532 to the positioning roller 51 and connecting and fixing the limit rod 533 to the limit roller 52, so as to ensure that the distance between the grinding unit 7 and the side of the curved glass is constant and vertical, thereby effectively limiting the grinding thickness of the grinding unit 7 and avoiding the problem of uneven grinding degree.

[0052] Under the elastic force of the calibration spring 64, the calibration pulley 62 can move on the two curved surfaces of the curved glass respectively. The telescopic guide rod 632 is kept in the center of the two calibration pulleys 62 by the elastic forces of the two calibration springs 64 in opposite directions and is located at a perpendicular position to the connecting line of the two calibration pulleys 62, ensuring the angle between the swing rod 631 and the side of the curved glass. By limiting the verticality, the grinding accuracy and the shape of each grinding position are guaranteed, so that the curved glass can be effectively and fully polished evenly.

[0053] The movable end of the driving mechanical arm 8 is fixed to the limit mounting plate 53, and the driving mechanical arm 8 moves by driving the limit mounting plate 53, driving the grinding head 73 to move along the side of the curved glass. At the same time, through the action of the torsion spring 72, the grinding head 73 can be fully pressed on the side of the curved glass, effectively ensuring the grinding effect. The distance limiting mechanism 5 and the angle calibration mechanism 6 are used to match various curved glasses with different curvatures, and the grinding shape and grinding thickness of curved glasses with different curvatures are kept consistent, effectively ensuring the grinding effect of the curved glass.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
