Description

Technical Field

[0001] The utility model belongs to the technical field of glass production equipment, and in particular relates to a position limiting tooling for a glass thinning workshop. Background Art

[0002] The existing glass thinning process is produced by top spray etching. The glass substrate is loaded by a jig for etching. The glass substrate is vertically inserted into the jig and then enters the processing machine. The acidic chemical solution in the etching machine is sprayed from the top for etching.

[0003] The tooling currently used in the spray etching workshop is composed of bottom teeth, side teeth and side baffles; among them, the side teeth are 35-tooth abacus bead side teeth, which are mainly used to fix the substrate glass in the setting frame for spray etching. Since the acid etching machine produces substrates to improve the apparent yield, the tooling will swing in the liquid medicine, so that the liquid medicine is sprayed evenly on the substrate, causing the substrate to shake left and right in the tooling, making the substrate close to the abacus bead or bumping against the abacus bead, resulting in uneven acid etching or even cracks on the surface of the substrate.

[0004] Therefore, the current spray line etching process uses the existing tooling as the abacus bead support substrate. The tooling has no other limiting support. The substrate will move back and forth between the abacus beads, get close to the abacus beads or bump against the abacus beads, resulting in uneven acid etching of the teeth and cracks after etching of the substrate glass.

[0005] For example, the patent document with the authorization announcement number CN215209143U discloses a glass substrate thinning clamping device, which includes two bottom frames, the bottom frames are connected to the top plates through the limit rods, the bottom frames are provided with threaded rods inside, the top ends of the threaded rods are fixedly connected to the first hand wheel, and the side surfaces of the threaded rods are threadedly connected to the lifting plates. The technical solution disclosed in the patent document cannot solve the technical problems described above. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a position limiting tool for a glass thinning workshop, the purpose of which is to improve the apparent yield of the glass.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a limit tooling for a glass thinning workshop, comprising a tooling body and a limit block arranged on the tooling body and used to control the distance between the glass substrate and the abacus beads to remain within a set range, and the limit block is made of a material that can expand after being heated.

[0008] The tool body is provided with a slot for the limit block to be embedded.

[0009] The material of the limit block is acid-resistant nylon.

[0010] The tool body is located below the abacus beads, and the length direction of the tool body is parallel to the length direction of the abacus beads.

[0011] The limiting block extends along the length direction of the tool body.

[0013] The utility model provides a limiting tool for a glass thinning workshop, which can limit the position of a glass substrate, so that the glass substrate will not be too close to or bump against abacus beads, thereby improving the apparent yield of the glass substrate.

[0020] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping technicians in the field to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model and facilitating its implementation.

[0021] like Figures 1 to 4 As shown, the utility model provides a limiting tool for a glass thinning workshop, comprising a tool body 1 and a limiting block 2 arranged on the tool body 1 and used to control the distance between a glass substrate 4 and an abacus bead 3 to remain within a set range, and the limiting block 2 is made of a material that can expand after being heated.

[0022] Specifically, if Figures 1 to 4As shown, a slot for embedding the limit block 2 is provided on the tool body 1 , the tool body 1 is located below the abacus beads 3 , the length direction of the tool body 1 is parallel to the length direction of the abacus beads 3 , and the limit block 2 extends along the entire length direction of the tool body 1 .

[0023] like Figure 1 As shown, the tool body 1 is a rectangular strip structure, threaded holes are arranged at both ends of the tool body 1, and the tool body 1 is installed on the production tool by bolts.

[0024] In this embodiment, the material of the stop block 2 is acid-resistant nylon. The stop block 2 is soft at 30°C-50°C, so that the glass substrate 4 will not get stuck or cracked when it touches the stop block 2. The stop block 2 is resistant to acidic liquid (HC l , H 2 SO 4 , HNO 3 , HF, etc.) has strong corrosion resistance and will not be corroded by acid.

[0025] A part of the limit block 2 is inserted into the slot of the tooling body 1, and the other part of the limit block 2 is located outside the tooling body 1. Due to the acidic environment of 30℃-50℃ during production, the limit block 2 will expand slightly due to heat, so it will not fall out of the tooling body 1. The assembled limit tooling is then fixed to the production tooling with bolts for normal production and use.

[0026] When installed on the production tooling, the limiting tooling can limit the glass substrate 4, and the limiting block 2 contacts the edge of the glass substrate 4, so that the glass substrate 4 will not be close to the abacus beads 3, thereby avoiding production risks and looking down (such as Figure 3 As shown), when the glass substrate 4 is close to the limiting block 2, there is still a certain distance from the abacus beads 3, so that the glass substrate 4 can be produced safely without producing a bad appearance.

[0027] The installation of the limiting tooling of the above structure does not increase the difficulty, and the installation is relatively simple, and employees do not need to perform complicated operations; the substrate can be limited so that the substrate will not be close to the abacus beads 3 or bump against them, thereby improving the apparent yield of the substrate.

[0028] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
