Description

Technical Field

[0001] This utility model belongs to the field of ultra-thin flexible glass production technology, and more specifically, it relates to an ultra-thin flexible glass acid etching structure that prevents liquid accumulation. Background Technology

[0002] UTG is a very thin glass material with advantages such as high strength, high transparency, and high heat resistance, and is widely used in smartphones, tablets, and foldable screens. However, in the current production process of ultra-thin flexible glass, the glass sometimes adheres to the tooling racks used in the strengthening stage. This adhesion can lead to acid buildup and fixture marks.

[0003] Existing technology includes a technique titled "A Micro-etching Fixture for Ultra-thin Flexible Glass," with publication number CN218879745U. This technique discloses a micro-etching fixture for ultra-thin flexible glass, comprising a base plate and side plates. Side plates are fixedly connected to the front and rear sides of the base plate. Several first fixing members are fixedly connected to the base plate, and several second fixing members are arranged between the front and rear side plates, with the second fixing members slidably connected to the side plates. Several relatively adjustable second fixing members are arranged between the side plates. That is, when the glass size is small, the distance between adjacent second fixing members is reduced; when the glass is large, several sets of second fixing members are tightly fitted to leave enough space between two sets of second fixing members to fix larger-sized glass. By adjusting the distance between the second fixing members according to the glass size, the space occupied by the glass in the fixture is maximized. This solves the problem of existing fixtures that only have two sets of positioning brackets in the horizontal direction, which can only fix one set of glass. When the glass fixed between them is small, it is impossible to fix multiple sets of glass, wasting etching fixture space and resulting in low etching efficiency.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is: to address the shortcomings of the existing technology by providing an ultra-thin flexible glass etching structure that is simple in structure, reliably limits the glass to be etched, ensures that the glass stands reliably during the etching process, prevents skipping between glass pieces, ensures that adjacent glass pieces are distributed evenly, effectively solves the problem of liquid accumulation during the glass etching process, does not produce clamp marks, and ensures good production stability and yield.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model is an ultra-thin flexible glass acid etching structure to prevent liquid accumulation. It includes a structural body, which includes multiple racks arranged on each rack. Each rack has multiple racks arranged at intervals. The vertical cross-section of the rack is triangular and the horizontal cross-section is rhomboid. Adjacent racks are arranged at intervals. Each rack forms a side limiting part of the ultra-thin flexible glass on its side.

[0008] The rack is connected to the rack arrangement member through a connecting part. The vertical cross-section of the connecting part has an inverted triangular structure, and the horizontal cross-section of the connecting part has a rhomboid structure.

[0009] The rack has a first limiting end cone on one side and a second limiting end cone on the other side.

[0010] The distance between the first limiting end cone and the second limiting end cone is set to be less than the thickness of the ultra-thin flexible glass.

[0011] The rack and pinion arrangement includes a top rack and pinion arrangement, a bottom rack and pinion arrangement, a left rack and pinion arrangement, and a right rack and pinion arrangement.

[0012] The ultra-thin flexible glass includes a top edge, a bottom edge, a left edge, and a right edge.

[0013] When positioning the ultra-thin flexible glass, the top edge of the ultra-thin flexible glass is configured to be able to be locked between two adjacent racks of the top rack arrangement member, and the bottom edge of the ultra-thin flexible glass is configured to be able to be locked between two adjacent racks of the bottom rack arrangement member.

[0014] The left end of the ultrathin flexible glass is configured to be able to be locked between two adjacent racks of the left rack arrangement member, and the right end of the ultrathin flexible glass is configured to be able to be locked between two adjacent racks of the right rack arrangement member.

[0015] When positioning the ultra-thin flexible glass, the end edge of the ultra-thin flexible glass is configured to be able to be locked onto the side limiting part of one rack and the side limiting part of another rack.

[0016] The rack and pinion arrangement members and the rack are structures made of corrosion-resistant materials.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] The ultra-thin flexible glass acid etching structure for preventing liquid accumulation described in this utility model comprises a structural body, which is a frame structure used to connect multiple rack-and-tooth arrangement members. These rack-and-tooth arrangement members are located in different positions: top, bottom, and both sides. Each rack-and-tooth arrangement member has multiple racks spaced apart, with adjacent racks spaced apart. Adjacent racks are used to clamp one end edge of a piece of glass. The rack structure is improved, with a triangular vertical cross-section and a rhomboid horizontal cross-section. This creates a side-limiting portion for the ultra-thin flexible glass on the side of each rack, with the side-limiting portion having an inclined diagonal structure. When the glass is clamped between two racks, the glass contacts the side-limiting portions of the two adjacent racks, achieving essentially point contact. The racks of the rack-and-tooth arrangement members located in different positions are used to clamp and limit the glass in other directions. By limiting the glass in four directions, the device reliably secures square-shaped ultra-thin flexible glass sheets, preventing movement and ensuring that the glass does not contact the rack arrangement members, but only the side limiting parts of the racks. This effectively ensures the etching and flow of the etching solution, solving the problem of liquid accumulation and improving defects caused by liquid accumulation and glass adhering to the side teeth. Multiple racks are used, with adjacent racks on each rack arrangement member forming a group to hold one end of an ultra-thin flexible glass sheet. One device can limit and etch multiple sheets of ultra-thin flexible glass, improving batch etching efficiency and overall work efficiency. The structure of this utility model features a rack (tooth) with an oblique line structure. This ensures that the glass remains upright during the acid etching process within the device. During production, the contact between the glass and the rack is not on a plane, but at an inclined angle. This prevents liquid from accumulating between the glass and the rack, allowing for reliable flow. This results in high product yield and stable processing. Due to the tooth position restriction, skipping teeth between glass pieces 5 will not occur, ensuring a dispersed distribution of the glass and guaranteeing good production stability. This also improves the problem of poor fixture marks caused by liquid accumulation on the rack due to old tooling. Attached Figure Description

[0023] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0024] As attached Figure 1 Appendix Figure 2As shown, this utility model is an ultra-thin flexible glass etching structure to prevent liquid accumulation. It includes a structural body, which comprises multiple rack-arranged rods 1. Each rack-arranged rod 1 has multiple racks 2 spaced apart. The vertical cross-section of each rack 2 is triangular, and the horizontal cross-section is rhomboid. Adjacent racks 2 are arranged at intervals. Each rack's side forms a side limiting portion 6 for the ultra-thin flexible glass 5. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In the structural design, a frame structure is constructed, which connects multiple rack-and-pinion members 1. These members 1 are located in different positions: top, bottom, and sides. Each rack-and-pinion member 1 has multiple racks 2 spaced apart. Adjacent racks 2 are spaced apart and used to hold one end of a piece of glass. The rack structure is improved: the vertical cross-section of rack 2 is triangular, and the horizontal cross-section is rhomboid. This creates a side-limiting portion 6 for the ultra-thin flexible glass 5 on the side of each rack 2, with the side-limiting portion 6 having an inclined diagonal structure. When the glass is held between two racks 2, the glass contacts the side-limiting portions of the two adjacent racks 2, achieving essentially point contact. The racks on the rack-and-pinion members 1 in different positions are used to hold and limit the glass in other positions. By limiting the glass in four directions, the square sheet-shaped ultra-thin flexible glass (glass) 5 is reliably positioned, preventing it from shifting. Furthermore, the glass 5 does not contact the rack and pinion rods 1, but only the side limiting part 6 of the rack. This effectively ensures the etching and flow of the acid etching solution, solving the problem of liquid accumulation and improving defects caused by liquid accumulation and glass adhering to the side teeth. Multiple racks 2 are provided, with adjacent racks 2 on each rack and pinion rod 1 forming a group, used to hold one end of an ultra-thin flexible glass 5. One device can achieve the positioning and etching of multiple ultra-thin flexible glass pieces 5, improving batch etching efficiency and overall work efficiency. The structure of this utility model features a diagonal rack 2 (tooth clamp), which ensures that the glass 5 remains upright during the acid etching process within the device. During production, the contact between the glass 5 and the rack 2 is not planar; due to the inclined angle, liquid cannot accumulate between the glass 5 and the rack 2, allowing reliable flow. This results in high product yield and stable processing. The tooth position restriction prevents skipping between glass 5s, ensuring a dispersed distribution and good production stability. This also improves upon the fixture marks caused by liquid accumulation on the racks in older tooling systems. The ultra-thin flexible glass acid etching structure described in this utility model, which prevents liquid accumulation, is simple in structure, reliably limits the glass to be etched, ensures the glass remains upright during etching, prevents skipping between glass pieces, and ensures a dispersed distribution between adjacent glass pieces. This effectively solves the problem of liquid accumulation during glass acid etching, prevents fixture marks, and ensures good production stability and yield.

[0025] The rack 2 is connected to the rack arrangement member 1 via a connecting part. The vertical cross-section of the connecting part is an inverted triangular structure, and the horizontal cross-section of the rack 2 is a rhomboid structure. This structure ensures the connection between the rack and the rack arrangement member 1, and the structure of the connecting part prevents fluid accumulation.

[0026] The rack 2 has a first limiting end cone 3 on one side and a second limiting end cone 4 on the other side. The distance between the first limiting end cone 3 and the second limiting end cone 4 is set to be less than the thickness of the ultra-thin flexible glass 5. This structure limits the minimum distance between the first limiting end cone 3 and the second limiting end cone 4 for clamping the glass, ensuring that when the glass is clamped, it can only contact the side limiting part 6 on the upper part of the first limiting end cone 3 and the side limiting part 6 on the upper part of the second limiting end cone 4, ensuring point contact and preventing liquid accumulation.

[0027] The rack and pinion arrangement member 1 includes a top rack and pinion arrangement member, a bottom rack and pinion arrangement member, a left rack and pinion arrangement member, and a right rack and pinion arrangement member. The ultra-thin flexible glass 5 includes a top edge, a bottom edge, a left edge, and a right edge. In the above structure, the four rack and pinion arrangement members are arranged at different positions on the glass to ensure that the glass is clamped and limited from different positions.

[0028] When positioning the ultra-thin flexible glass 5, the top edge of the ultra-thin flexible glass 5 is configured to be engaged between two adjacent racks 2 of the top rack arrangement member, and the bottom edge of the ultra-thin flexible glass 5 is configured to be engaged between two adjacent racks 2 of the bottom rack arrangement member. The left edge of the ultra-thin flexible glass 5 is configured to be engaged between two adjacent racks 2 of the left rack arrangement member, and the right edge of the ultra-thin flexible glass 5 is configured to be engaged between two adjacent racks 2 of the right rack arrangement member. When positioning the ultra-thin flexible glass 5, the edge of the ultra-thin flexible glass 5 is configured to be engaged at the side limiting part 6 of one rack 2 and the side limiting part 6 of the other rack 2. This structure reliably limits the glass and effectively prevents liquid accumulation.

[0029] The rack and pinion members 1 and 2 are made of corrosion-resistant materials. This structure ensures the device's corrosion resistance, guarantees long-term use, extends its lifespan, and reduces costs.

[0030] The ultra-thin flexible glass acid etching structure for preventing liquid accumulation described in this utility model comprises a structural body, which is a frame structure. The structural body connects multiple rack-and-pinion members 1, located in different positions: top, bottom, and sides. Each rack-and-pinion member 1 has multiple racks 2 spaced apart, with adjacent racks 2 spaced apart. Adjacent racks are used to hold one end edge of a piece of glass. The rack structure is improved: the vertical cross-section of the rack 2 is triangular, and the horizontal cross-section is rhomboid. Thus, each rack 2 forms a side limiting part 6 for the ultra-thin flexible glass 5, which is an inclined diagonal structure. When the glass is held between two racks 2, the glass contacts the side limiting parts of the two adjacent racks 2, achieving essentially point contact. The racks of the rack-and-pinion members 1 located in different positions are used to hold and limit the glass in other positions. By limiting the glass in four directions, the square sheet-shaped ultra-thin flexible glass (glass) 5 is reliably positioned, preventing it from shifting. Furthermore, the glass 5 does not contact the rack and pinion rods 1, but only the side limiting part 6 of the rack. This effectively ensures the etching and flow of the acid etching solution, solving the problem of liquid accumulation and improving defects caused by liquid accumulation and glass adhering to the side teeth. Multiple racks 2 are provided, with adjacent racks 2 on each rack and pinion rod 1 forming a group, used to hold one end of an ultra-thin flexible glass 5. One device can achieve the positioning and etching of multiple ultra-thin flexible glass pieces 5, improving batch etching efficiency and overall work efficiency. The structure of this utility model features a rack 2 (tooth) with an oblique line structure. This ensures that the glass 5 remains upright during the acid etching process within the device. During production, the contact between the glass 5 and the rack 2 is not on a plane, but at an inclined angle. This prevents liquid from accumulating between the glass 5 and the rack 2, allowing for reliable flow. This results in high product yield and stable processing. Due to the tooth position restriction, skipping teeth between the glass 5 will not occur, ensuring that the glass 5 is distributed evenly and guaranteeing good production stability. This also improves the problem of poor fixture marks caused by liquid accumulation on the rack due to old tooling.
