Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultra-thin glass processing technology, specifically to a shatterproof support frame for chemical tempering of UTG glass. Background Technology
[0002] With its excellent properties such as lightness, thinness, high strength, and high light transmittance, UTG (ultra-thin glass) has shown broad application prospects in high-end electronic fields such as foldable screen phones, wearable devices, and automotive displays. Chemical tempering, as a key process to improve the performance of UTG glass, involves immersing UTG glass in molten salt, allowing the ions in the molten salt to exchange with the ions on the glass surface, forming a compressive stress layer on the glass surface, thereby enhancing the strength and impact resistance of the glass.
[0003] In the chemical tempering process of UTG glass, the tempering frame plays a crucial supporting and fixing role, and its performance directly affects the effect of chemical tempering and the quality of UTG glass. However, due to the ultra-thin nature of UTG glass, existing traditional tempering frames have exposed many defects during chemical tempering (such as molten salt immersion), which seriously restricts the stability of the UTG glass chemical tempering process and product quality.
[0004] In a high-temperature chemical tempering environment, UTG glass will undergo thermal expansion. After expansion, the gap between the glass and the frame becomes smaller, making it prone to collisions with the frame during the expansion process. Due to the ultra-thinness and brittleness of UTG glass, such collisions can easily cause the glass to shatter. Furthermore, the molten salt is in a flowing state during the chemical tempering process, and traditional tempering frames cannot effectively restrain the position of the UTG glass. The force generated by the flowing molten salt can cause the glass to float and shift, changing its position in the molten salt and affecting the uniformity of ion exchange. This not only leads to inconsistent performance of the chemically tempered glass and reduces the overall quality of the product, but may also cause damage due to collisions with other components caused by glass displacement.
[0005] In addition, during the chemical tempering process, factors such as molten salt flow and equipment vibration can cause UTG glass to vibrate. Insufficient lateral fixation cannot effectively suppress this vibration, which can easily lead to glass vibration and breakage. Rigid clamping methods are difficult to precisely control the force when applying clamping force, which can easily cause excessive compression on the edge of UTG glass, resulting in microcracks.
[0006] In view of the above, this application is hereby submitted. Utility Model Content
[0007] The purpose of this invention is to provide a shatterproof support frame for chemical tempering of UTG glass, in order to solve the problems mentioned in the background art.
[0008] To solve the above-mentioned technical problems, this utility model provides a shatterproof support frame for chemical tempering of UTG glass, including an outer frame. A bottom support strip is slidably abutted against the inner wall of the outer frame. The bottom support strip includes several V-shaped corrugated plates, which are interconnected. A contact strip is provided at the top of each V-shaped corrugated plate. Side plates are fixedly installed on the side walls of both sides of the V-shaped corrugated plates. The outer walls of the two side plates slidably abut against the inner wall of the outer frame. The bottom support strip has toothed grooves at both the top and bottom. The entire bottom support strip has an array of V-shaped cutouts with a tooth height of 0.5-1mm and a tooth pitch of 2-3mm. A side toothed module and a top pressure toothed module are slidably installed on the inner wall of the outer frame.
[0009] Furthermore, the outer frame includes a connecting frame, the side wall of which is provided with a horizontal groove and a vertical groove, the inner wall of the horizontal groove is slidably connected to the end of the outer wall of the side rack module, and the inner wall of the vertical groove is slidably connected to the end of the outer wall of the top pressure rack;
[0010] The transverse grooves are arranged in two rows, with ten transverse grooves in each row.
[0011] Furthermore, the arc-shaped groove contact surfaces inside the side rack module and the top pressure rack are both arc-shaped grooves that wrap around the glass edge. The arc-shaped grooves use high-temperature resistant metal wool to cushion the glass and prevent thermal expansion and cracking.
[0012] Furthermore, the vertical slots are vertically opened, and there are three vertical slots. Each vertical slot has a top pressure rack slidably installed on its inner wall. The outer frame is made of nickel-based alloy material, and its coefficient of thermal expansion matches that of UTG.
[0013] Furthermore, the side rack module includes a rack, a connecting shaft is fixedly installed on the outer side wall of the rack, and an arc-shaped groove is fixedly installed at the end of the connecting shaft;
[0014] The internal structure of the side rack module is the same as that of the top pressure rack, and the arc-shaped groove opening inside the top pressure rack is vertically downward.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The bottom support strip uses eight interconnected V-shaped corrugated plates, with the overall V-shaped hollows arranged in an array. This line contact support method can evenly distribute the stress on the UTG glass, effectively avoiding local stress concentration, and providing sufficient space for the flow of molten salt. This avoids the problem of inconsistent glass performance after chemical tempering due to the change of glass position in molten salt affecting the uniformity of ion exchange, thus reducing the overall quality of the product.
[0017] 2. The side rack module and the top pressure rack, which are slidably installed on the inner wall of the outer frame, work together to achieve omnidirectional limiting of the UTG glass. The side rack module fixes the glass from the side to prevent it from moving laterally when the molten salt flows or the equipment vibrates. The top pressure rack presses the glass from above, completely suppressing the floating phenomenon of the glass in the molten salt. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4This utility model provides a technical solution: a shatterproof support frame for chemical tempering of UTG glass, comprising an outer frame 1, with a bottom support strip 2 slidably abutting against the inner wall of the outer frame 1. The bottom support strip 2 includes several V-shaped corrugated plates 203, which are interconnected and arranged in an array of V-shaped perforations. The tooth height is 0.5-1mm and the tooth spacing is 2-3mm. Compared with traditional flat supports, this design can evenly distribute the force on the UTG glass, effectively avoiding local stress concentration and reducing the possibility of the glass breaking due to improper bottom support during chemical tempering. A contact strip 204 is provided at the top of the V-shaped corrugated plates 203, and side plates 201 are fixedly installed on the side walls of both sides of the V-shaped corrugated plates 203. The outer walls of the two side plates 201 slide against the inner wall of the outer frame 1. The bottom support strip 2 has toothed grooves 202 at both the top and bottom. The toothed grooves 202 and the array-type V-shaped hollow structure provide ample space for the flow of molten salt. During the molten salt immersion process of chemical tempering, the molten salt can flow smoothly at the bottom of the glass, reducing the impact and obstruction of the molten salt on the glass, which helps to improve the quality and uniformity of chemical tempering. The inner wall of the outer frame 1 is slidably installed with side toothed modules 3 and top pressure toothed strips 4. The two work together to achieve omnidirectional limiting of the UTG glass. The side toothed modules 3 fix the glass from the side to prevent the glass from moving laterally when the molten salt flows or the equipment vibrates. The top pressure toothed strips 4 press the glass from above, completely suppressing the floating phenomenon of the glass in the molten salt and ensuring that the glass maintains a stable position during the chemical tempering process.
[0025] Please see Figure 3 This utility model provides a technical solution: a shatterproof support frame for chemical tempering of UTG glass, including a side rack module 3 including a rack 301. A connecting shaft 302 is fixedly installed on the outer wall of the rack 301, and an arc groove 303 is fixedly installed at the end of the connecting shaft 302. The rack 301 of the side rack module 3 is fixed to the arc groove 303 through the connecting shaft 302 on the outer wall. During installation, the rack 301 can slide along the outer frame 1 close to the side wall of the UTG glass, so that the arc groove 303 wraps around the edge of the glass, thereby achieving stable lateral support for the glass. The internal structure of the side rack module 3 is the same as the internal structure of the top pressure rack 4. The internal structure of the top pressure rack 4 is the same as that of the side rack module 3, but its internal arc groove 303 opens vertically downward. After installation, the vertically downward arc groove 303 can completely wrap around the top edge of the glass from above, giving the glass vertical downward pressure and completely suppressing the floating phenomenon of the glass in molten salt. The dual lateral and vertical restraints enable omnidirectional fixation of the UTG glass, ensuring its stability during the chemical tempering process.
[0026] Please see Figure 1 , Figure 2This utility model provides a technical solution: a shatterproof support frame for chemical tempering of UTG glass, including an outer frame 1 and a connecting frame 101. The side wall of the connecting frame 101 is provided with a horizontal groove 102 and a vertical groove 103. The horizontal groove 102 on the side wall of the connecting frame 101 is slidably connected to the end of the outer wall of the side rack module 3. During installation, the side rack module 3 can slide along the horizontal groove 102 to a suitable position and fit against the side wall of the UTG glass. The sliding connection method ensures that the side rack module 3 accurately limits the lateral position of the glass, preventing the glass from shifting laterally due to factors such as molten salt flow and equipment vibration during the chemical tempering process, and providing stable and reliable lateral support for the glass. The inner wall of the horizontal groove 102 is slidably connected to the end of the outer wall of the side rack module 3, and the inner wall of the vertical groove 103 is slidably connected to the end of the outer wall of the top pressure rack 4.
[0027] Please see Figure 2 This utility model provides a technical solution: a shatterproof support frame for chemical tempering of UTG glass, including two rows of transverse grooves 102, with ten transverse grooves 102 in each row. The two rows of ten transverse grooves 102 provide ample adjustment space. For smaller glass sizes, the operator can select the transverse grooves 102 closer to the inner side to install the side rack module 3, thereby fixing the glass. For larger glass sizes, the outer transverse grooves 102 can be used to ensure that the side rack module 3 can cover the entire side wall of the glass.
[0028] Please see Figure 2 This utility model provides a technical solution: a shatterproof support frame for chemical tempering of UTG glass, including three vertical grooves 103. Each vertical groove 103 has a top pressure tooth 4 slidably installed on its inner wall. Because the vertical grooves 103 are vertically opened, the top pressure tooth 4 installed in them can slide down along the vertical direction. During the chemical tempering process, UTG glass may have a tendency to float in the molten salt due to buoyancy and other factors. At this time, the vertically pressing top pressure tooth 4 can apply uniform and stable vertical pressure to the glass from above, effectively suppressing the floating phenomenon of the glass and ensuring that the glass is always in the correct position.
[0029] Please see Figure 2This utility model provides a technical solution: a shatterproof support frame for chemical tempering of UTG glass, including a side rack module 3 and a top pressure rack 4. The contact surfaces of the arc-shaped grooves 303 inside are all arc-shaped grooves. This shape can match the edge curve of the UTG glass and wrap around the glass edge. When the side rack module 3 and the top pressure rack 4 fix the glass, the arc-shaped grooves can tightly wrap the glass edge, increase the contact area, and make the fixation more secure. Compared with flat contact, it can better disperse the pressure on the glass edge, avoid local stress concentration, and reduce the risk of glass damage due to uneven force. The arc-shaped grooves 303 use cushioning high-temperature resistant metal wool. This metal wool has good elasticity and cushioning performance, and can absorb and disperse stress when the glass expands thermally, reduce the tensile stress on the glass edge, and effectively prevent the glass from cracking due to thermal expansion.
[0030] Please see Figure 1 , Figure 2 This utility model provides a technical solution: a shatterproof support frame for chemically tempered UTG glass, including an outer frame 1 made of nickel-based alloy material, and the coefficient of thermal expansion of this material is matched with that of UTG. This means that when the UTG glass and the nickel-based alloy outer frame 1 undergo thermal expansion or contraction with temperature changes, since their coefficients of thermal expansion are matched, their expansion or contraction is similar during temperature changes, which can effectively avoid excessive thermal stress between the glass and the outer frame 1 due to differences in thermal expansion.
[0031] Working principle: During the chemical tempering of UTG glass, firstly, based on the glass specifications, the positions of the side rack module 3 and the top pressure rack 4 are adjusted using the two rows of twenty horizontal grooves 102 and three vertically opened grooves 103 set on the outer frame 1. The UTG glass is then placed on the bottom support strip 2 inside the outer frame 1, which consists of eight interconnected V-shaped corrugated plates 203 with contact strips 204. The bottom support strip 2 has an array of V-shaped cutouts with a tooth height of 0.5-1mm and a tooth pitch of 2-3mm. Its line contact support method ensures uniform stress on the glass, avoiding the problems of insufficient bottom support and bending stress concentration caused by traditional planar support. The side rack module 3 is slid so that its tooth 301 is close to the glass sidewall. The arc-shaped groove 303 fixed by the connecting shaft 302 wraps around the edge of the glass. The groove 303 has a circular arc groove on the contact surface and uses high-temperature resistant metal wool for cushioning. It can fully fix the glass laterally and buffer the high-temperature expansion and compression, preventing vibration cracking caused by insufficient lateral fixation and edge micro-cracks caused by rigid clamping. The sliding top pressure rack 4 has the same internal structure as the side rack module 3. The vertically downward arc groove 303 completely wraps around the top edge of the glass from above, suppressing the floating and displacement of the glass in the molten salt. After installation, the support frame is placed in the molten salt for chemical tempering. During this process, the nickel-based alloy material used in the outer frame 1 has a thermal expansion coefficient that matches that of UTG, reducing the risk of collision between the glass and the frame due to the difference in thermal expansion. After chemical tempering is completed, the top pressure rack 4 and the side rack module 3 are released in sequence, and the UTG glass is removed, completing the entire chemical tempering process.
