TECHNICAL FIELD

[0001] The present application relates to the field of glass processing, in particular to a glass etching clamp. BACKGROUND

[0002] With the continuous expansion of the mobile market, the technology of mobile terminals has also made breakthrough development, the most representative of which is the folding smart phone.

[0003] The folding smart phone needs to use ultra-thin glass because it uses an OLED (Organic Light-Emitting Diode) panel. The ultra-thin glass is used to be pasted on the screen of the smart device to provide protection for the screen, and its thickness is about 30-100 microns.

[0004] This requires the thickness of the glass to be reduced to below 0.1 mm through an etching process. In the etching process, the clamp supporting the glass is made of a corrosion-resistant material because the glass needs to be soaked in an etching solution.

[0005] In the prior art, the etching solution is generally hydrofluoric acid (HF), and the clamp supporting the glass is generally made of synthetic resin as a whole to ensure durability. However, due to the limited structural strength of synthetic resin materials, the clamp may deform when fixing dozens or even hundreds of pieces of glass, which reduces the fixing effect of the glass and leads to a decrease in the yield of the glass.

[0031] Embodiments of the present application are described in detail below with reference to the attached drawings. The embodiments described below are examples of the present application and are not intended to limit the present application.

Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The following is for reference. Figures 1-5 A glass etching fixture 100 according to an embodiment of the present invention is described.

[0035] like Figures 1-2 As shown, a glass etching fixture 100 according to an embodiment of the present invention includes: a frame 10, a fixture rod 20, a support rod 30, a seal 40, and a fixing member 50. The fixture rod 20 is connected to the frame 10. A support groove 21 is formed on the outer surface of the fixture rod 20 for supporting the edge of the glass. The fixture rod 20 has a core hole 22 extending along the length of the fixture rod 20, and the core hole 22 has an opening 221 at least at one end of the fixture rod 20. The support rod 30 is disposed within the core hole 22, which includes a filling groove 223 located between the support rod 30 and the opening 221. The seal 40 fills the filling groove 223 to seal the support rod 30. The fixing member 50 connects the frame 10 and the fixture rod 20.

[0036] In other words, the clamping rod 20 is connected to the frame 10 by the fastener 50, and the frame 10 is the supporting base of the glass etching fixture 100. The support groove 21 provided on the clamping rod 20 is used to support the edge of the glass. When the clamping rod 20 clamps the glass, the clamping rod 20 applies a clamping force to the glass, and the glass applies pressure from the clamping rod 20.

[0037] The support rod 30 is arranged in the clamping hole 22 in the clamp rod 20, and the clamping hole 22 extends along the length direction of the clamp rod 20, so the support rod 30 is also arranged in the clamp rod 20 along the length direction of the clamp rod 20. By arranging the support rod 30 in the clamp rod 20, the deflection of the clamp rod 20 can be reduced when the clamp rod 20 is subjected to force, the clamp rod 20 can bear a larger weight of glass, and the support rod 30 is not prone to bending deformation when bearing the weight, so that the glass is firmly clamped on the glass etching clamp 100, and the yield of the glass is improved.

[0038] In the present application, the clamping hole 22 in the clamp rod 20 is arranged to have an opening 221 at least at one end, so as to facilitate the arrangement of the support rod 30 in the clamp rod 20. For example, in some schemes, the clamp rod 20 and the support rod 30 are machined respectively, and the support rod 30 can be inserted into the clamping hole 22 from the opening 221. In some schemes, the clamp rod 20 is injection molded on the surface of the support rod 30, and the support rod 30 needs to be fixed in the injection mold during injection molding. A fixing structure can be arranged at one end of the support rod 30, and the fixing structure is withdrawn from the clamp rod 20 after the clamp rod 20 is formed. The fixing structure can be withdrawn from the clamp rod 20 through the opening 221.

[0039] In the present application, the frame 10, the clamp rod 20 and the fixing member 50 are all made of anticorrosive material, so that the glass etching clamp 100 can support the glass in an acidic environment to complete the etching process.

[0040] It can be understood that, since the use environment of the glass etching clamp 100 has a certain corrosiveness, in the present application, a filler groove 223 is arranged between the support rod 30 and the opening 221 in the clamping hole 22, and the sealing member 40 is filled in the filler groove 223, and the sealing member 40 is also made of anticorrosive material, so as to prevent the acidic liquid from corroding the support rod 30 and prolong the service life of the clamp rod 20.

[0041] Here, when the clamping hole 22 has an opening 221 at one end, the clamping hole 22 is provided with a filler groove 223 at the end, and the sealing member 40 is filled to seal. When the clamping hole 22 has openings 221 at both ends, the clamping hole 22 is provided with filler grooves 223 at both ends, and the sealing member 40 is filled to seal.

[0042] Specifically, the number of support grooves 21 on a single clamp rod 20 is multiple, and the multiple support grooves 21 are arranged along the length direction of the clamp rod 20. Therefore, a single support groove 21 can support a single piece of glass, and multiple support grooves 21 can support multiple pieces of glass. Moreover, the multiple support grooves 21 are arranged along the length direction of the clamp rod 20, and the multiple pieces of glass supported can be arranged at intervals, so that etching processing of multiple pieces of glass can be realized in the etching process, and the production efficiency is improved.

[0043] All the support grooves 21 on the clamp rod 20 are provided with the support rod 30, that is, the pressure of the glass clamped on the support groove 21 can be applied on the support rod 30, so that each glass can be well supported.

[0044] Optionally, the outer wall surface of the support rod 30 is tightly fitted with the inner wall surface of the sandwich hole 22, and the support rod 30 is made of metal. Thus, the support rod 30 made of metal has the advantage of greater bending strength, and when the weight of the glass supported by the clamp rod 20 increases, the support rod 30 can provide greater bending strength for the clamp rod 20, so that the clamp rod 20 will not be deformed due to the excessive weight of the glass, thereby improving the carrying capacity of the clamp rod 20.

[0045] The tightly fitted outer wall surface of the support rod 30 with the inner wall surface of the sandwich hole 22 can prevent the formation of a gap between the support rod 30 and the sandwich hole 22, thereby reducing the strength of the clamp rod 20. Moreover, it can prevent the corrosion liquid from entering between the support rod 30 and the sandwich hole 22 to cause corrosion of the support rod 30, thereby providing better sealing effect for the support rod 30 to increase the service life of the glass etching clamp 100.

[0046] It should be noted that the cross-sectional shape of the support rod 30 and the sandwich hole 22 perpendicular to the length extension direction of the clamp rod 20 is not specifically limited, and the cross-sectional shape of the support rod 30 and the sandwich hole 22 can be circular, triangular or rectangular. For the support rod 30, different cross-sectional shapes have different bending strengths under the same area, and the glass weight that the clamp rod 20 bears in actual use can be selected. The cross-sectional shape of the sandwich hole 22 is the same as that of the support rod 30.

[0047] In the scheme of the present application, there are various ways to fix the clamp rod 20 on the frame 10 by using the fixing member 50.

[0048] For example, as shown in Figure 2 In some embodiments, the part of the sandwich hole 22 between the filler groove 223 and the opening 221 constitutes a plug hole 222, and the fixing member 50 is connected to the frame 10 and fits in the plug hole 222. Thus, the fixing member 50 can connect the clamp rod 20 and the frame 10 by fitting with the plug hole 222, so as to fix the clamp rod 20.

[0049] In some other embodiments, a mounting hole is provided on the clamp rod 20 adjacent to the end portion, the fixing member 50 is arranged at the mounting hole, and then the frame 10 is connected.

[0050] In some optional embodiments, one end of the clamp rod 20 has an opening 221 to form a plug hole 222, and the other end is connected to the frame 10 by a buckle. In this way, one end of the clamp rod 20 can be connected to the frame 10 by the fixing member 50, and the other end is connected to the frame 10 by the buckle, which can reduce the use of the fixing member 50 under the premise of fixing the clamp rod 20, thereby reducing the assembly process and improving production efficiency.

[0051] In some specific embodiments, as shown in Figure 2 and Figure 3 both ends of the clamp rod 20 have openings 221, and both ends of the clamp rod 20 can form plug holes 222. In this way, the fixing member 50 can be used to fix both ends of the clamp rod 20, making the clamp rod 20 more secure.

[0052] Further, in the cross section perpendicular to the length direction of the clamp rod 20, the projection of the plug hole 222 completely covers the projection of the filler groove 223. When the glass etching clamp 100 is installed, the sealing member 40 needs to be filled into the filler groove 223, and the sealing member 40 needs to be filled into the filler groove 223 from the opening 221 of the clamp rod 20 through the plug hole 222. In the cross section perpendicular to the length direction of the clamp rod 20, the projection of the plug hole 222 completely covers the projection of the filler groove 223, which can make the filling of the sealing member 40 more convenient, thereby reducing the installation difficulty of the glass etching clamp 100 and increasing the assembly efficiency.

[0053] It should be noted that the projection shape of the plug hole 222 and the projection shape of the filler groove 223 in the cross section perpendicular to the length direction of the clamp rod 20 are not limited, and the projection shape of the plug hole 222 and the projection shape of the filler groove 223 can be circular, square or polygonal, which can be selected according to the shape of the fixing member 50 and the sealing member 40. Of course, the projection shape of the plug hole 222 and the projection shape of the filler groove 223 can be the same or different, as long as the projection of the plug hole 222 can completely cover the projection of the filler groove 223.

[0054] Optionally, the plug hole 222 and the filler groove 223 are both circular holes, and the inner diameter of the filler groove 223 is smaller than that of the plug hole 222. Thus, the circular plug hole 222 and the filler groove 223 are not prone to forming gaps when the sealing member 40 and the fixing member 50 are assembled into the fixture rod 20, and the sealing effect of the sealing member 40 and the fixing member 50 on the fixture rod 20 can be improved, thereby prolonging the service life of the glass etching fixture 100. In addition, the plug hole 222 and the filler groove 223 are both circular holes, and the cross section of the fixing member 50 and the sealing member 40 in the plug hole 222 and the filler groove 223 also needs to be circular. In actual manufacturing, the fixing member 50 and the sealing member 40 with a circular cross section are easier to process, thereby reducing the manufacturing cost of the glass etching fixture 100.

[0055] As shown in FIG. 1, in some embodiments, the fixing member 50 is in extrusion contact with the sealing member 40. The two adjacent surfaces of the fixing member 50 and the sealing member 40 are in extrusion contact, which can achieve a better sealing effect and prolong the service life of the glass etching fixture 100. Figure 3

[0056] In the scheme of the present application, the sealing member 40 is very flexible to set.

[0057] In some specific embodiments, the sealing member 40 is a sealing block, which is in interference fit in the filler groove 223. The interference fit of the sealing block and the filler groove 223 enables the sealing block to tightly adhere to the filler groove 223, thereby achieving a better sealing effect.

[0058] Optionally, the sealing block is configured as a cylinder. Since the filler groove 223 is a circular hole, the sealing block is configured as a cylinder and is in interference fit in the filler groove 223, which can prevent gaps from occurring between the filler groove 223 and the sealing block, thereby achieving a better sealing effect.

[0059] In other specific embodiments, the sealing block can be a sealing glue. When the glass etching fixture 100 is assembled, the sealing glue is filled into the filler groove 223, and then the fixture rod 20 is fixed to the frame 10 by the fixing member 50. After the sealing glue dries, it tightly adheres to the inner wall of the filler groove 223, thereby achieving a sealing effect. By filling the sealing glue into the filler groove 223, the assembly difficulty can be reduced, and the amount of the sealing glue can be controlled. Different amounts of the sealing glue can be filled according to the needs to achieve different sealing performances.

[0060] When the sealing member 40 is a sealing block, as shown in FIG. 1, optionally, the sealing member 40 is an elastic ball. Thus, when the sealing member 40 is filled into the filler groove 223, it can extrude the inner wall of the filler groove 223 due to its elasticity after being compressed, so that there is no gap between the filler groove 223 and the sealing member 40, thereby improving the sealing effect. Figure 2 ​​

[0061] Furthermore, the outer diameter of the seal 40 is larger than the outer diameter of the packing groove 223. Therefore, when the seal 40 is an elastic sphere, its outer surface protrudes from the packing groove 223. When the fixing member 50 fixes the clamp rod 20, the plane of the fixing member 50 near the packing groove 223 will press against the seal 40. This pressing action of the two surfaces strengthens the sealing effect, preventing corrosion of the support rod 30 and improving the service life of the glass etching fixture 100.

[0062] In some embodiments, any one of the frame 10, clamping rod 20, seal 40, and fixing member 50 is a synthetic resin component. When etching glass, hydrofluoric acid (HF) is generally used to etch the glass surface to obtain glass of different thicknesses. By making the frame 10, clamping rod 20, and seal 40 from synthetic resin, corrosion of the glass etching fixture 100 by hydrofluoric acid (HF) can be effectively prevented, thereby improving its service life.

[0063] In some embodiments, the support rod 30 is injection molded and embedded within the clamping rod 20. This allows the support rod 30 and the clamping rod 20 to be manufactured as a single unit, improving the sealing performance of the clamping rod 20 to the support rod 30 and thus extending the service life of the glass etching fixture 100. Simultaneously, the integral molding of the support rod 30 and the clamping rod 20 reduces the assembly difficulty of the glass etching fixture 100 and lowers production costs.

[0064] like Figure 4 As shown, in some embodiments, the frame 10 includes at least two panels 11, with a clamping rod 20 located between the two panels 11. Both ends of the clamping rod 20 are connected to the panels 11 via fasteners 50. Thus, the clamping rod 20 can be fixed to the frame 10 via the panels 11, improving the stability of the clamping rod 20 on the frame 10, enabling it to withstand more glass, thereby increasing production output.

[0065] like Figure 5 As shown, the panel 11 further includes mounting holes 111, through which the fastener 50 passes, and a portion of the fastener 50 fits into the sandwich hole 22. Thus, the fastener 50 can fix the clamp rod 20 to the panel 11 via the mounting holes 111, thereby securing the clamp rod 20. By fixing the clamp rod 20 to the panel 11, the glass etching fixture 100 becomes a single unit, making its structure more stable and increasing its service life.

[0066] It should be noted that the structure of the fixing member 50 is not limited here, and the fixing member 50 can be cylindrical or bolt-shaped. When the fixing member 50 is cylindrical, an interference fit is formed between the fixing member 50 and the sandwich hole 22. Thus, when the fixing member 50 is finally fitted in the sandwich hole 22 by passing through the mounting hole 111, an extrusion fit can be formed with the inner wall of the sandwich hole 22, so that a better sealing effect can be provided for the support rod 30, thereby increasing the service life of the glass etching clamp 100.

[0067] Alternatively, the fixing member 50 is a bolt, and the two ends of the sandwich hole 22 are threaded holes, and the bolt is threadedly connected with the threaded holes. Thus, by threadedly connecting, the fixing member 50 can fix the clamp rod 20 on the frame 10, and by controlling the depth of the bolt screwed into the sandwich hole 22, the extrusion force of the bolt on the sealing member 40 can be controlled, so that the clamp rod 20 has a better sealing effect and prevents the support rod 30 from corroding.

[0068] Further, the two ends of the clamp rod 20 are fixed on the frame 10 by bolts, so that when different specifications of clamp rods 20 need to be replaced, the clamp rod 20 can be replaced by disassembling the bolts, thereby increasing the expandability of the glass etching clamp 100.

[0069] Of course, the fixing member 50 of the present application is not limited to a bolt, and can be adjusted according to the connection position and connection method of the fixing member 50. For example, the fixing member 50 can be a fixed pin, and the clamp rod 20 is rotatably connected to the frame 10 by the fixed pin.

[0070] As shown in FIG. 1, Figure 4 In some embodiments, the clamp rod 20 is spaced apart and multiple, and the two ends of each clamp rod 20 are connected to the panel 11 by the fixing member 50. By spacing the clamp rods 20, multiple directions of support can be provided for the glass, so that the glass is fixed more firmly in the glass etching clamp, preventing the glass from moving, thereby increasing the yield of glass etching.

[0071] Alternatively, the clamp rod 20 includes at least three rows arranged in the horizontal direction. Thus, two adjacent rows of clamp rods 20 can fix a piece of glass, and three rows of clamp rods 20 can reinforce two pieces of glass, and so on. By arranging more rows of clamp rods 20, multiple pieces of glass in the horizontal direction can be reinforced, and when the number of support grooves 21 is multiple, multiple pieces of glass can be supported on each clamp rod 20. At this time, the glass etching clamp 100 can support multiple pieces of glass, so that multiple pieces of glass can be etched in the etching process, thereby greatly increasing the production efficiency.

[0072] Further, each column of the clamp rods 20 can be provided with at least one row. The clamp rods 20 provided with one row can fix one layer of glass, and when each column of the clamp rods 20 is provided with multiple rows, multiple rows of glass can be fixed, thereby increasing the number of glasses fixed and supported by the glass etching clamp 100, and improving the production efficiency.

[0073] As shown in Figure 5 Optionally, the at least one mounting hole 111 is a long hole, and the fixing member 50 has a fastened state and a relaxed state, and the position of the fixing member 50 along the length direction of the mounting hole 111 is adjustable when the fixing member 50 is in the relaxed state. Thus, the clamp rods 20 can be slid in the mounting hole 111 when the fixing member 50 is in the relaxed state, so that the spacing between the two clamp rods 20 changes. In this way, different specifications of glass can be etched without replacing a new glass etching clamp 100, thereby increasing the expansibility of the glass etching clamp 100 and reducing the production cost.

[0074] Further optionally, when the clamp rods 20 are provided in three columns, the mounting hole 111 corresponding to the middle clamp rod 20 is a round hole, and the mounting holes 111 corresponding to the clamp rods 20 on both sides are long holes. Thus, when the spacing of the clamp rods 20 is adjusted to adapt to different specifications of glass, the adjustment of the positions of the clamp rods 20 on both sides can adapt to different specifications of glass, thereby reducing the adjustment process of the clamp rods 20 and increasing the production efficiency.

[0075] Optionally, the frame 10 includes multiple connecting rods 12 connected between the two face plates 11. The connection of the two face plates 11 by the connecting rods 12 can make the structure of the frame 10 more stable, so that the frame 10 can bear more weight of glass, thereby etching a larger number of glasses in one etching process to improve the yield.

[0076] Further optionally, the two ends of the multiple connecting rods 12 are connected to the four corners of the two face plates 11. In this way, when the glass etching clamp 100 is fixed and removed, the frame 10 can be more stable without affecting the loading and unloading of the glass.

[0077] As shown in Figure 2As shown, in some embodiments, the support groove 21 is arranged around the clamp rod 20, and the support groove 21 has two ring walls 211 which are arranged to extend towards each other in the direction towards the support rod 30. The support groove 21 is arranged around the clamp rod 20, so that the clamp rod 20 can support the glass without needing to adjust the angle when connected to the panel 11, thereby reducing the difficulty of assembly. The glass is supported between the two ring walls 211 of the support groove 21, and since the ring walls 211 are arranged to extend towards each other in the direction towards the support rod 30, the glass can be more easily placed into the support groove 21 of the glass etching clamp 100, and even if the glass is skewed during the prevention process, the angle can be automatically adjusted by the inclined surfaces of the two ring walls 211 to achieve fixation. Moreover, the edge of the glass is supported between the two ring walls 211, so that the contact area between the glass and the support groove 21 is smaller, and when the glass is subjected to the etching process, a better etching effect can be achieved to improve the yield.

[0078] The following describes the specific structure of a glass etching clamp 100 according to an embodiment of the present application: Figures 1-2 The following describes the specific structure of a glass etching clamp 100 according to an embodiment of the present application:

[0079] The glass etching clamp 100 comprises a frame 10, a clamp rod 20, a support rod 30, a sealing member 40 and a fixing member 50.

[0080] The frame 10 comprises two panels 11 having mounting holes 111 and a plurality of connecting rods 12 connected between the two panels 11.

[0081] The clamp rod 20 is connected between the two panels 11 by the fixing member 50, and the outer surface of the clamp rod 20 is formed with a plurality of support grooves 21 for supporting the edge of the glass. The support groove 21 is arranged around the clamp rod 20, and the support groove 21 has two ring walls 211 which are arranged to extend towards each other in the direction towards the support rod 30.

[0082] The clamp rod 20 has a sandwich hole 22 therein, and the sandwich hole 22 has openings 221 at both ends of the clamp rod 20.
