[0020] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Typical embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0022] Figure 1 The exploded view of the clamping device for three-dimensional curved glass provided by an embodiment of the present utility model is shown. As Figure 1 shown, the clamping device for three-dimensional curved glass provided by the present utility model includes a carrier plate 10 and a plurality of clamping modules. Among them, a plurality of glass loading positions 110 for loading the glass to be clamped are provided on the carrier plate 10, and each glass loading position 110 is used in cooperation with a clamping module. Specifically, each clamping module includes an upper cover plate 210, a buckle assembly 220, and a bottom plate assembly 230. Among them, a plurality of placement grooves 2101 imitating the body positions of the glass are provided on the upper cover plate 210. The upper cover plate 210 and the buckle assembly 220 are locked on the glass loading position 110 through threaded connection. After placing the three-dimensional curved glass to be processed into the upper cover plate 210, the bottom plate assembly 230 is buckled and pressed and fixed through the buckle assembly 220. The present utility model adopts a buckle structure, and the fixture can be locked by manually pushing the buckle, which saves the time for finding tools to screw the screws, simplifies the operation, and thus improves the production efficiency.

[0023] Figure 2 The figure shows an exploded view of a buckle assembly of a clamping device for three-dimensional curved glass provided by an embodiment of the present utility model; Figure 4 The figure shows a sectional view of a buckle assembly of a clamping device for three-dimensional curved glass provided by an embodiment of the present utility model. As Figure 2 and Figure 4 shown, the buckle assembly 220 includes a buckle body 2201, a plurality of buckle baffles 2202, a plurality of dowel screws 2203, a plurality of ball plungers 2204 and a plurality of locking springs 2205. Among them, each buckle baffle 2202 includes a connection groove 22021 and a plurality of mounting holes 22022. The buckle baffle 2202 is installed on the side flange 22011 of the buckle body 2201 through the connection groove 22021. The dowel screw 2203 is installed in the mounting hole 22022. The ball plunger 2204 is installed in the groove on the lower surface of the buckle body 2201. The locking spring 2205 is sleeved outside the dowel screw 2203. The buckle assembly of the present utility model is composed of a dowel screw, a locking spring, a buckle baffle, a buckle body and a ball plunger, and is locked on the carrier plate through a threaded connection. The ball plunger is stuck in two different slots of the buckle to achieve quick clamping; through the limit of the dowel screw and the elastic force of the spring to press the buckle baffle, the baffle can move upward under force to realize the pressing and fixing of different clamping depths of the cover plate. In the present utility model, a locking spring is added to the buckle assembly, and it is not necessary to be completely matched to just press the upper and lower clamping plates, so the adaptability of the fixture is improved, and the processing difficulty and cost of the fixture are reduced.

[0024] Furthermore, since the locking method of the buckle baffle is through spring pressing, the compressible margin of the spring is the allowable range of the assembly error of the jig. If the compressible margin of the spring is (3 - 5) mm, the allowable range of the assembly error of the fixture is within (3 - 5) mm; and the thickness error of the bottom plate assembly, the depth error of the glass loading position of the carrier plate, and the assembly error caused by the different flatness of the two are all within 0.2 mm, which is much smaller than (3 - 5) mm. Therefore, the clamping device for three-dimensional curved glass can eliminate the influence of processing errors and assembly errors on the clamping of the fixture.

[0025] Figure 6 The figure shows a sectional view of the closing and opening of a buckle assembly of a clamping device for three-dimensional curved glass provided by an embodiment of the present utility model. As Figure 6As shown in the figure, the snap component of the clamping device for three-dimensional curved glass provided by the present utility model adopts a spring plunger clamping structure, meeting the need for quick clamping. The most common clamping method of the fixture is to lock by screwing. This method is not only cumbersome, but also the screws are prone to slipping teeth after repeated tightening, resulting in the scrapping of the fixture. The clamping device for three-dimensional curved glass provided by the present utility model designs a grooved snap through the spring clamping feature of the ball plunger, and realizes quick positioning and buckling by the ball head pressing in the card slot.

[0026] Figure 3 The figure shows an exploded schematic view of the bottom plate assembly of the clamping device for three-dimensional curved glass provided by an embodiment of the present utility model. Figure 5 The figure shows a sectional view of the bottom plate assembly of the clamping device for three-dimensional curved glass provided by an embodiment of the present utility model. As Figure 3 and 5 As shown in the figure, the bottom plate assembly 230 includes a bottom plate 2301 and a plurality of pressing components. A plurality of pressing grooves 23011 are formed on the bottom plate 2301, and the pressing components are installed in the pressing grooves 23011. Each pressing component includes a pressing block 2302, a plurality of spring baffles 2303 and a plurality of pressing springs 2304. First spring mounting holes 23021 are provided on two sides of the pressing block 2302, second spring mounting holes 23031 are formed on the spring baffles 2303, and two ends of the pressing spring 2304 are respectively installed in the first spring mounting hole 23021 and the second spring mounting hole 23031. The bottom plate assembly provided by the present utility model is composed of a spring baffle, a pressing spring, a pressing block and a bottom plate, and is fastened by screws and pressed and fixed in the glass loading position of the carrier plate through a snap component. During use, the pressing spring provides a thrust for the pressing block, so that each piece of glass can bear the pressure of the pressing block and be pressed and fixed. By adding a pressing block and a pressing spring structure in the bottom plate assembly, the pressing block is always pressed against the glass by elastic force, avoiding the problem of gap loosening caused by uneven fixture processing and glass processing errors, and realizing the simultaneous pressing of multiple glasses by the same bottom plate assembly.

[0027] Furthermore, affected by the processing capacity and the existing preparation technology, the glass thickness and the depth of the placement groove of the upper cover plate cannot be made completely consistent, which leads to the inconsistency of the glass placing height position. A single upper cover plate fixture cannot simultaneously press multiple glasses, and the loose glasses will shake and cause overplating. The bottom plate assembly of the clamping device for three-dimensional curved glass provided by the present utility model adopts a structure of spring pressing a single pressing block, so that each piece of glass can be independently pressed and fastened. Therefore, the jig can eliminate the influence of glass processing accuracy on the clamping and fixing of the product.

[0028] Furthermore, by calculating the bearing strength of the glass at high temperatures, the range of the clamping force can be determined. The preloading depth and adjustment height of the compression spring 2304 are determined through the elastic force calculation formula F = kΔL, and a reasonable spring size design fixture is selected. In addition, the components that need to be clamped by the buckle are the glass to be clamped and the bottom plate assembly, and the clamping step can be completed by offsetting its gravity effect with elastic force. The required preloading pressure of the spring is calculated (F = kΔL) to be slightly greater than the gravity of the clamping component. At this time, the buckle is not too tight and will not loosen.

[0029] Figure 7 The figure shows a schematic diagram of the operation process of using the clamping device for three-dimensional curved glass provided by the embodiment of the present invention. As Figure 7 shown, when in use, first, the glass to be clamped is positioned and placed in the placement groove 2102 of the upper cover plate; then, the bottom plate assembly 230 is covered and the buckle assembly 220 is tightened for fixation; subsequently, the clamping device is hung on the inner electric film of the equipment, and the clamping device is removed after the electric film process; the buckle assembly is unscrewed, and the bottom plate assembly is taken out; the glass is taken out and placed in the plug board or glue box, and the above operations are repeated.

[0030] The clamping device for three-dimensional curved glass provided by the present invention is composed of an upper cover plate, a carrier plate, a buckle assembly, and a bottom plate assembly. The upper cover plate and the buckle assembly are locked on the carrier plate through threaded connections; the bottom plate assembly is pressed and fixed through the buckle assembly. The bottom plate assembly is clamped tightly by the spring buckle, realizing fast and stable clamping; at the same time, the bottom plate assembly adopts a spring structure, and each pressing block is pressed through elastic force, realizing the simultaneous clamping function of multiple glasses. In addition, the above structures are all hidden and designed inside the fixture panel, which will not increase the thickness of the fixture, so it will not affect the clamping of the machine tool and is applicable to almost all glass installation fixtures.

However, it can be understood that the embodiments of the present invention can be practiced without these specific details.
