[0002] Ultra-thin glass is an indispensable accessory for the production of folding mobile phones. Ultra-thin glass is a very thin glass material, usually in the range of a few microns to tens of microns. Therefore, in order to ensure the output during production, it is necessary to ensure stability and prevent breakage. At the same time, the quality of the product and the improvement of production efficiency will be the most important link in the development of this product. The problem existing in the prior art is that the glass currently produced is 70-30μm, which has the characteristics of thin thickness and brittle material.

The etching tool and the ultra-thin glass are placed upright in the surface etching tank, and there is a clearance fit between the ultra-thin glass and the cavity on the etching tool for placing the ultra-thin glass. The setting of etching tooling and de-printing mechanism can not only effectively optimize etching for plates with a thickness of 30-100μm and a size of 50*50-300*400mm, but also ensure that the surface of the finished ultra-thin glass has no fixture marks or defects, while ensuring that the ultra-thin glass has high impact resistance.

DETAILED DESCRIPTION

[0018] The following is a further detailed description of the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various components involved, the function and working principle of each part, etc., through the description of the embodiments with reference to the accompanying drawings: As attached Figure 1 -Attached Figure 3As shown, the present invention is an ultra-thin glass etching device, comprising a first outer plate 1, a second outer plate 2, a clamping plate 3, and a positioning pin 4. One end of a plurality of positioning rods 5 is connected to the first outer plate 1, and the other end of a plurality of positioning rods 5 is connected to the second outer plate 2. A plurality of sleeves 6 are installed on each positioning rod 5 according to the gap, and a back plate 7 is installed between adjacent sleeves 6 on each positioning rod 5. The back plate 7 and the clamping plate 3 are both hollow frame structures in the middle. The first outer plate 1 and the second outer plate 2 are both hollow frame structures in the middle. The inner circle of each back plate 7 is respectively provided with a back plate positioning groove capable of clamping the edge of the ultra-thin glass 8. A locking movable part 16 is provided on the side of each clamping plate 3, and a locking pin shaft 9 is provided on the side of each back plate 7. A pin hole 10 is provided on each locking pin shaft 9. The above structure proposes an improved technical solution in view of the deficiencies in the prior art. When setting up the structure, the first outer panel 1, the second outer panel 2, the clamping plate 3, and the positioning pin 4 are made respectively. The first outer panel 1, the second outer panel 2, the clamping plate 3, and the back panel 7 are all hard structures that will not be easily deformed and protect the glass when clamping the glass. Then the device needs to be assembled. During assembly, a plurality of sleeves 6 are installed on each positioning rod 5 according to the gap, and a back panel 7 is installed between adjacent sleeves 6 on each positioning rod 5. One end of the plurality of positioning rods 5 is connected to the first outer panel 1, and the other end of the plurality of positioning rods 5 is connected to the second outer panel 2. In this way, the plurality of positioning rods are connected to the outer panels, and the plurality of back panels are also reliably fixed. When the glass needs to be fixed, each back panel and a corresponding clamping plate can fix a piece of ultra-thin glass. First, the back plate positioning groove is located in the inner circle of each back plate 7, and then the corresponding clamp is mounted on the corresponding ultra-thin glass. After the back plate 7 and the corresponding clamp 3 clamp an ultra-thin glass 8, the locking movable part 16 on the side of the clamp 3 is flipped and clamped on the locking pin 9 on the side of the corresponding back plate 7. Then the positioning pin 4 is passed through the pin hole 10 on the locking pin 9 from the outside of the locking movable part 16, so that the locking of the locking back plate 7 and the clamp 3 is achieved through the locking of multiple locking movable parts and the locking pin. Then the assembled etching device is sent into the etching liquid for glass etching. The back plate 7 and the clamp 3 are both hollow frame structures in the middle, so that both sides of the ultra-thin glass 8 are exposed to the outside, which is convenient for the etching liquid to reliably contact the ultra-thin glass 8 through the hollow structure during etching. The first outer plate 1 and the second outer plate 2 are both hollow frame structures in the middle, which is convenient for the etching liquid to circulate through the hollow structure and contact the ultra-thin glass between the first outer plate 1 and the second outer plate 2, improve the circulation of the etching liquid, and improve the etching effect. The ultra-thin glass etching device of the present invention has a simple structure and can reliably clamp the ultra-thin glass and complete the etching operation. The device will not be easily deformed, thus protecting the ultra-thin glass and avoiding damage, ensuring the product yield and etching uniformity, and improving product quality. At the same time, the ultra-thin glass can be clamped and removed conveniently, thus improving production efficiency, reducing production costs, and reducing the labor intensity of operators.

[0019] The inner circle of the clamping plate 3 is provided with a clamping plate positioning groove, and the clamping plate 3 positioning groove is set to a structure that can be clamped on the outer edge and outer side edge of the ultra-thin glass 8, and the ultra-thin glass 8 is set to a structure that can be clamped in the back plate positioning groove of the inner circle of the corresponding back plate 7 at the same time. In the above structure, the back plate and the clamping plate are both provided with positioning grooves of step structures to clamp and position the glass from both sides to ensure that the glass will not move. The hollow structure of the back plate and clamping plate does not affect the contact of the etching liquid with the glass.

[0020] The positioning rod 5 includes a plurality of upper positioning rods 11, a plurality of lower positioning rods 12 and a plurality of middle positioning rods 13. In the above structure, the plurality of upper positioning rods 11, the plurality of lower positioning rods 12 and the plurality of middle positioning rods 13 are reliably connected to the first outer plate and the second outer plate to achieve structural fixation, and after the shaft sleeve and the back plate are positioned, the back plate will not axially move relative to the positioning rod, and the shaft sleeve limits the distance between adjacent back plates, which is convenient for placing glass and clamping plates, and after the glass and clamping plates are placed, there is still a gap between the clamping plates and the adjacent back plates, which is convenient for operation.

[0021] Each side corner of the upper part of the first outer panel 1 passes through an upper positioning rod 11, and a positioning nut 14 is screwed on the threaded portion of each upper positioning rod 11 located on the outer side of the first outer panel 1. Each side corner of the upper part of the second outer panel 1 passes through an upper positioning rod 11, and a positioning nut 14 is screwed on the threaded portion of each upper positioning rod 11 located on the outer side of the second outer panel 1. Each side corner of the lower part of the first outer panel 1 passes through a lower positioning rod 12, and a positioning nut 14 is screwed on the threaded portion of each lower positioning rod 12 located on the outer side of the first outer panel 1. Each side corner of the lower part of the second outer panel 1 passes through a lower positioning rod 12, and a positioning nut 14 is screwed on the threaded portion of each lower positioning rod 12 located on the outer side of the second outer panel 1. A middle positioning rod 13 passes through each side of the middle of the first outer plate 1, and a positioning nut 14 is screwed on the threaded portion of each middle positioning rod 13 located on the outer side of the first outer plate 1, and a positioning nut 14 is screwed on the threaded portion of each middle positioning rod 13 located on the outer side of the second outer plate 1. Specifically, the above structure can be provided with two upper positioning rods 11 at the upper part, two middle positioning rods 13 at the middle part, and two lower positioning rods 12 at the lower part. In this way, the structure of the entire etching device is stable, the positioning rods are fixed by the first outer plate 1 and the second outer plate 2, and the multiple back plates 7 are fixed in position by multiple positioning rods and sleeves.

[0022] After the back plate 7 and the corresponding clamping plate 3 are clamped with a piece of ultra-thin glass 8, the locking movable member 16 on the side of the clamping plate 3 is configured to be flipped and clamped on the locking pin 9 on the side of the corresponding back plate 7. The positioning pin 4 is configured to be able to pass through the pin hole 10 on the locking pin 9 from the outside of the locking movable member 16 to lock the back plate 7 and the clamping plate 3. The above structure, as embodiment 1, the locking movable member 16 and the locking pin 9 are limited by the positioning pin passing through the small hole.

[0023] Alternatively, as embodiment 2, a threaded portion is provided on the outside of the locking pin shaft 9 provided on the side of each back plate 7, and the locking movable member 16 on the side of the clamping plate 3 is provided with a structure that can be flipped over and clamped onto the locking pin shaft 9 on the side of the corresponding back plate 7, and the threaded portion is provided with a structure that can be screwed with the corresponding locking nut. The above structure can also be directly limited by the locking nut.

[0024] Each side of each clamping plate 3 is movably hinged with multiple locking movable parts 16 from top to bottom. The above structure can realize locking of multiple parts from both sides and reliably clamp the ultra-thin glass.

[0025] The ultra-thin glass etching device described in the present invention is structured to respectively make the first outer plate 1, the second outer plate 2, the clamping plate 3, and the positioning pin 4. The first outer plate 1, the second outer plate 2, the clamping plate 3, and the back plate 7 are all structures with hardness and will not be easily deformed. They can reliably protect the glass when clamping the ultra-thin glass. Then, the etching device needs to be assembled. During assembly, a plurality of sleeves 6 are mounted on each positioning rod 5 according to the gap, and a back plate 7 is mounted between adjacent sleeves 6 on each positioning rod 5. One end of the plurality of positioning rods 5 is connected to the first outer plate 1, and the other end of the plurality of positioning rods 5 is connected to the second outer plate 2. In this way, the plurality of positioning rods are connected to the outer plates, and the plurality of back plates are also reliably fixed. When the glass needs to be fixed, each back plate and a corresponding clamping plate can fix a piece of ultra-thin glass. First, the back plate positioning groove is located in the inner circle of each back plate 7, and then the corresponding clamp is mounted on the corresponding ultra-thin glass. After the back plate 7 and the corresponding clamp 3 clamp an ultra-thin glass 8, the locking movable part 16 on the side of the clamp 3 is flipped and clamped on the locking pin 9 on the side of the corresponding back plate 7. Then the positioning pin 4 is passed through the pin hole 10 on the locking pin 9 from the outside of the locking movable part 16, so that the locking of the locking back plate 7 and the clamp 3 is achieved through the locking of multiple locking movable parts and the locking pin. Then the assembled etching device is sent into the etching liquid for glass etching. The back plate 7 and the clamp 3 are both hollow frame structures in the middle, so that both sides of the ultra-thin glass 8 are exposed to the outside, which is convenient for the etching liquid to reliably contact the ultra-thin glass 8 through the hollow structure during etching. The first outer plate 1 and the second outer plate 2 are both hollow frame structures in the middle, which is convenient for the etching liquid to circulate through the hollow structure and contact the ultra-thin glass between the first outer plate 1 and the second outer plate 2, improve the circulation of the etching liquid, and improve the etching effect.

[0026] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
