Description

Technical Field

[0001] This utility model belongs to the field of glass processing technology, and specifically relates to a vacuum adsorption type glass cutting anti-deviation positioning mechanism. Background Technology

[0002] Glass is a common amorphous solid, mainly made from raw materials such as quartz sand, soda ash, and limestone, which are melted at high temperatures and then rapidly cooled. Due to the irregular arrangement of its internal atoms and the absence of a fixed melting point, its core characteristic is high transparency. It also possesses good chemical stability, heat resistance, and processability. It can be shaped through processes such as cutting, grinding, and coating, and its applications span multiple fields: in architecture, it is used for doors, windows, and curtain walls; in the electronics field, it is used as a screen substrate; in daily necessities, it covers utensils and lenses; in the medical field, it can be used to make syringes, test tubes, etc. Modern technology has further led to the development of special glass such as bulletproof, laminated, and conductive glass, continuously expanding its application boundaries.

[0003] In existing positioning mechanisms for vacuum adsorption glass cutting, the position of the vacuum adsorption structure needs to be adjusted individually when positioning glass plates of different sizes to adapt to the glass plate of that size. However, this method is time-consuming and labor-intensive, which increases the burden on the staff. Utility Model Content

[0004] The purpose of this invention is to address the anti-deviation positioning mechanism for vacuum adsorption type glass cutting, which has the advantage of automatically adapting to the position fixing of glass plates of various sizes.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vacuum adsorption type glass cutting anti-deviation positioning mechanism, including a base, three sets of sliding seat housings welded to the upper end of the base, two sets of uprights slidably connected inside the sliding seat housings, and tension springs connected to the uprights and sliding seat housings via spring fixing components. Inclined plates are welded to the surfaces of the three sets of uprights. Electric push rods are bolted to the interior of the uprights, and transmission connecting rods are bolted to the piston end of the electric push rods. A rotating shaft is welded inside the transmission connecting rod, and a movable block is rotatably connected to the surface of the rotating shaft. Two sets of fixed rods are welded to the surface of the movable block, and a suction cup is threaded to one end of each fixed rod.

[0006] Compared with existing technologies, the beneficial effects of this utility model are: 1. To address the problem of inaccurate positioning and reduced cutting quality caused by glass plate shifting due to external force or inertia during existing glass cutting processes, this utility model achieves guiding and stable positioning through a sliding seat housing, a support frame, a tension spring, and an inclined plate welded to the base. Specifically, when installing the glass plate, it is placed on the upper end of the sliding seat housing and pushed forward. During the movement, the glass plate slides along the inclined surface of the inclined plate. Since the inclined plate is made of tempered glass with a smooth surface, frictional resistance is reduced, allowing the glass plate to move smoothly. At the same time, the support frame slides within a rectangular groove through a limiting block, which effectively prevents the support frame from moving out and ensures stable movement. When the glass plate stops being pushed, the inclined plate automatically adjusts its position under the restoring force of the tension spring, allowing the glass plate to accurately reach the preset cutting position, thereby achieving fast and high-precision positioning, avoiding the errors of traditional manual adjustment, and improving cutting efficiency and yield. 2. To address the problems of easily damaged suction cups and complex replacement processes in existing vacuum adsorption mechanisms, leading to long equipment downtime and high maintenance costs, this utility model achieves rapid switching and convenient replacement through an electric push rod, transmission connecting rod, rotating shaft, movable block, fixed rod, and suction cup. Specifically, during normal operation, the electric push rod drives the transmission connecting rod downward, causing the suction cup to adhere to the glass plate surface. When one suction cup is damaged, the rotating shaft rotates the movable block, which in turn drives the spare fixed rod and suction cup to switch to the working position, achieving seamless switching. If both sets of suction cups are damaged, since the suction cups and fixed rods are connected by threads, the damaged suction cup can be directly unscrewed and a new suction cup installed without disassembling the entire mechanism. This solution reduces replacement time, lowers maintenance difficulty, and ensures the continuity of the cutting process and production efficiency. Attached Figure Description

[0009] The present invention will be further described in detail below with reference to the accompanying drawings.

[0010] As one embodiment of this utility model, reference is made to Figure 1 - Figure 3 The vacuum adsorption type glass cutting anti-deviation positioning mechanism includes a base 1, three sets of sliding seat housings 2 are welded to the upper end of the base 1, two sets of uprights 5 are slidably connected inside the sliding seat housings 2, and tension springs 3 are connected to the uprights 5 and the sliding seat housings 2 by spring fixing components. Inclined plates 7 are welded to the surfaces of the three sets of uprights 5. Electric push rods 8 are bolted to the inside of the uprights 5. A transmission connecting rod 11 is bolted to the piston end of the electric push rod 8. A rotating shaft 17 is welded to the inside of the transmission connecting rod 11. A movable block 18 is rotatably connected to the surface of the rotating shaft 17. Two sets of fixed rods 15 are welded to the surface of the movable block 18. A suction cup 16 is threaded to one end of the fixed rod 15.

[0011] Furthermore, two sets of rectangular sliding grooves 6 are provided on the surface of the sliding seat housing 2, and the rectangular sliding grooves 6 are rectangular. A limit block 4 is welded to one side of the support frame 5, and the limit block 4 is slidably connected to the rectangular sliding groove 6.

[0012] Based on the above technical concept, it can be understood that when installing the glass plate, the glass plate is placed on the upper end of the sliding seat housing 2 and then pushed forward. During the pushing process, the glass plate will slide on the inclined surfaces of the two sets of inclined plates 7. Since the inclined surfaces of the inclined plates 7 are made of tempered glass and have a relatively smooth surface, when the inclined plates 7 are pressed by the glass plate, the inclined plates 7 on both sides will drive the uprights 5 to move to both sides inside the sliding seat housing 2 respectively. During the movement of the uprights 5, the limiting blocks 4 will slide inside the rectangular slide groove 6. The limiting blocks 4 are used to limit the movement of the uprights 5 and prevent the uprights 5 from moving out of the sliding seat housing 2. When the inclined plates 7 stop moving due to the pushing of the glass plate, the glass plate has moved to a suitable position. At this time, the electric push rod 8 can drive the transmission link 11 to move down, and the transmission link 11 drives the suction cup 16 to press down and adhere to the surface of the glass plate. When one of the suction cups 16 is damaged, the movable block 18 can be rotated using the rotating shaft 17. When the movable block 18 rotates, it will drive the spare set of fixed rods 15 and suction cups 16 to be switched out for use. When both sets of suction cups 16 are damaged, since the suction cups 16 and the fixed rods 15 are connected by threads, the two damaged sets of suction cups 16 can be disassembled and replaced.

[0013] In one embodiment of this utility model, reference is made to Figure 2 and Figure 3The transmission connecting rod 11 has sliding rods 13 slidably connected to both sides inside. A clamping plate 14 is welded to one end of each sliding rod 13, and the clamping plate 14 is detachably connected to the fixing rod 15. An installation rod 19 is fixedly connected to one end of each sliding rod 13. A threaded block 12 is welded to one end of the installation rod 19, and the middle of the installation rod 19 is cylindrical. A bidirectional threaded screw 10 is threadedly connected between the two sets of threaded blocks 12, with threads located at both ends. The bidirectional threaded screw 10 is rotatably connected to the transmission connecting rod 11. A rotating handle 9 is welded to one end of the bidirectional threaded screw 10, and the surface of the rotating handle 9 has an anti-slip groove, which is arc-shaped.

[0014] Based on the above technical concept, it can be understood that when switching to the backup suction cup 16, the rotating handle 9 will be rotated. During the rotation of the rotating handle 9, the bidirectional threaded screw 10 will rotate inside the transmission link 11. When the bidirectional threaded screw 10 rotates, it will drive the two sets of threaded blocks 12 to move in opposite directions, thereby causing the two sets of threaded blocks 12 to drive the two sets of mounting rods 19 to move in opposite directions. In turn, the two sets of mounting rods 19 will drive the two sets of sliding rods 13 to move in opposite directions inside the transmission link 11. Finally, the two sets of sliding rods 13 will drive the two sets of clamping plates 14 to move in opposite directions and clamp them on the surface of the fixing rod 15. This will fix the position of the fixing rod 15 and prevent the suction cup 16 from detaching from the glass plate when using the suction cup 16 to fix the glass plate due to the rotation of the fixing rod 15.

[0015] In one embodiment of this utility model, it should be noted that the proposed spring fixing member is provided on the mounting hole on the sliding seat housing 2 or the upright 5. In this embodiment, it specifically refers to the mounting hole or mounting seat provided on the sliding seat housing 2 or the upright 5. Its core function is to serve as a reliable connection point for both ends of the tension spring 3. In practical applications, it is preferably a metal pin fixed on the side wall of the sliding seat housing 2. One end of the tension spring 3 is directly hooked onto this pin, and the other end is hooked onto a similar hook on the upright 5. When the upright 5 is subjected to force and moves to stretch the tension spring 3, the rebound force generated by the tension spring will be effectively transmitted between the sliding seat housing 2 and the upright 5 through the spring fixing members at both ends, thereby providing a stable restoring force for the upright 5. This ensures that the inclined plate 7 can automatically and smoothly return to its initial position after being squeezed by the glass plate.

[0016] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
