Description

Technical Field

[0001] This utility model relates to the field of tempered glass handling technology, and in particular to a tempered glass handling device. Background Technology

[0002] Tempered glass is a type of safety glass. It is actually a prestressed glass. To increase its strength, chemical or physical methods are typically used to create compressive stress on the glass surface. When the glass is subjected to external force, this surface stress is first neutralized, thus improving its load-bearing capacity and enhancing its resistance to wind pressure, temperature changes, and impacts. Due to its high strength and safety, tempered glass is widely used in construction, furniture, and automotive industries. However, tempered glass presents challenges during handling due to its fragility, weight, and diverse sizes. Traditional handling methods, relying primarily on manual labor or simple mechanical devices, have the following drawbacks:

[0003] 1. Low efficiency of manual handling: Large or irregularly shaped tempered glass requires multiple people to work together, which is labor-intensive and poses safety hazards; 2. Limited fixing methods: Traditional suction cup handling devices usually use fixed suction points, which are difficult to adapt to glass of different sizes and shapes, and are prone to breakage due to uneven force; 3. Insufficient adjustment capabilities: Existing handling equipment lacks precise adjustment functions for height and suction force, making it difficult to adapt to glass of different thicknesses or curved surfaces; 4. Poor stability: It is easily affected by vibration or tilting during handling, which may cause the glass to slip or break.

[0004] Therefore, there is an urgent need for a handling device that can adapt to tempered glass of different specifications and has stable adsorption and precise adjustment functions to improve handling efficiency and safety. Utility Model Content

Detailed Implementation

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In the attached diagram, all identical reference numerals refer to the same components.

[0025] Example 1: Handling standard-sized flat tempered glass, such as Figures 1-4 As shown, this embodiment addresses the handling of common architectural flat tempered glass (600×900mm, 5-8mm thick). The specific structural connections and working process are as follows:

[0026] Support structure assembly: Four support shafts 11 are vertically fixed on the carrying platform of the trolley 1, with a spacing of 500mm between adjacent support shafts 11. The lifting plate 12 is sleeved on the middle of the support shafts 11 and can slide along the axial direction of the support shafts 11, with a lifting stroke of 400mm. The lower end of the telescopic sleeve 142 of the height adjustment support 17 is fixedly connected to the lifting plate 12, and the upper end is connected to the fixed base 21 of the clamping device 2 through the locking bolt 141.

[0027] Please see the appendix Figure 4The clamping device is positioned as follows: The fixed base 21 is a rectangular frame structure with two vertical support columns 22 symmetrically arranged at the center, and a central fixed plate 23 with a diameter of 300mm is fixed at the top. Two central suction cups 24 are installed parallel to each other on the central fixed plate 23, with a spacing of 150mm between the suction cups. Four sets of sliding support components 25 are evenly distributed on the fixed base 21. Each set includes: a linear guide rail 251: 300mm in length, fixed to the fixed base 21; a slider 252: which can slide along the guide rail 251 with a stroke of 250mm; an L-shaped connecting rod 253: vertically fixed to the side of the slider 252; a sub-fixed plate 26: connected to the top of the connecting rod 253 through a universal joint 254; and three edge suction cups 27: distributed in an equilateral triangle on the sub-fixed plate 26.

[0028] Working principle of the drive mechanism: The rack seat 281 is fixed to the center of the fixed base 21 by bolts. The drive motor 282 is fixed in the middle of the drive rod 283. The gear 282a meshes with the spur rack 281a inside the rack seat 281. The two ends of the drive rod 283 are connected to the first hinge hole 253a of the connecting rod 253 by pins 255. During operation, the gear 282a drives the rack 281a to move, which in turn drives the four sets of sliding support components 25 to extend and retract synchronously through the drive rod 283, with a maximum adjustment range of 200mm.

[0029] Glass adsorption process: The central suction cup 24 first contacts the central area of ​​the glass. The drive assembly 28 drives the four sets of sliding support assemblies 25 to unfold outward, so that the edge suction cups 27 contact the edge of the glass. The pressure sensor 241 monitors the pressure of each suction cup in real time, and adjusts the negative pressure value to -0.07MPa through the air pressure regulating valve 133 to ensure stable adsorption.

[0030] Example 2: Handling of large-size curved tempered glass

[0031] This embodiment is applicable to the handling of curved tempered glass (2000×1500mm, thickness 8-10mm) for building curtain walls. Its main structural features are as follows:

[0032] Clamping device adjustments: The dimensions of the fixed base 21 are increased to 2200mm × 1600mm. The diameter of the central fixing plate 23 is increased to 400mm, and the distance between the two central suction cups 24 is adjusted to 250mm. The length of the linear guide rail 251 of the four sets of sliding support assemblies 25 is extended to 400mm, and the stroke of the slider 252 is increased to 350mm.

[0033] Curved surface adaptive mechanism: The fixed plate 26 can be adjusted by ±20° around the top of the connecting rod 253 via the universal joint 254. The edge suction cup 27 adopts an extended design, with the suction surface diameter increased to 80mm, ensuring full contact with the curved glass surface.

[0034] Drive parameter optimization: The power of drive motor 282 is increased to 150W, and the module of gear 282a is increased to 2mm to ensure sufficient driving force to extend the sliding support assembly 25 to a maximum stroke of 350mm. The width of guide groove 281b is increased to 15mm to improve motion stability.

[0035] Adsorption force control: The monitoring range of pressure sensor 241 is extended to -0.05~-0.12MPa. The pressure of each suction cup is automatically adjusted according to the curvature of the glass. The pressure in the arc apex area is controlled at -0.08MPa, and the pressure in the edge area is appropriately increased to -0.1MPa to ensure overall adsorption balance.

[0036] Example 3: Handling of irregularly shaped tempered glass

[0037] This embodiment addresses the handling requirements of tempered glass with holes or special shapes (maximum size 1500×1000mm), and the main improvements include:

[0038] The clamping device has been modified: the central fixing plate 23 has been changed to a detachable structure, allowing for the replacement of different sizes of central fixing plates 23 according to the shape of the glass. The position of the edge suction cup 27 on the secondary fixing plate 26 can be adjusted within a range of ±50mm to adapt to asymmetrical layouts.

[0039] Suction cup configuration adjustment: Some edge suction cups 27 can be replaced with miniature suction cup sets for adsorbing small protrusions or reinforcing ribs on the edges of glass. Each miniature suction cup set contains 3 small suction cups with a diameter of 20mm, and the total adsorption area is equivalent to that of standard suction cups.

[0040] Improved driving precision: The rolling bearing 284 has been upgraded to a precision grade, and the surface roughness Ra of the guide groove 281b is ≤0.8μm, ensuring that the positioning accuracy of the sliding support assembly 25 reaches ±0.5mm, which meets the special adsorption requirements of irregularly shaped glass.

[0041] Pneumatic control system: The number of pressure sensors 241 is increased to allow each suction cup to be independently configured, enabling more precise pressure control. The response time of the pneumatic regulating valve 133 is reduced to 0.5 seconds, which can quickly compensate for pressure fluctuations caused by changes in the shape of the glass.

[0042] The above embodiments demonstrate the specific implementation of the tempered glass handling device of this utility model in different application scenarios. By adjusting the structural parameters and adsorption control parameters of the clamping device, it can adapt to the handling needs of tempered glass of various specifications and shapes.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
