Description

Technical Field

[0001] The utility model belongs to the technical field of large-size glass production, and more specifically relates to a large-size glass spray etching limit clamp. Background Art

[0002] Currently, in the glass thinning industry, spray etching is the primary method for thinning large-size glass (G5 and above). The spray carrier tooling is equipped with a certain number of limit clamps to enable simultaneous production of multiple sheets of glass, improving etching efficiency. Existing limit clamps have certain drawbacks: The clamps directly contact the edge of the glass at a single point, resulting in a small contact area. This creates a high impact force on the glass during the swing etching process, making it prone to edge damage such as cracking or jamming.

[0003] The prior art includes a technique entitled "A Clip for Liquid Crystal Glass Etching Process" with a publication (announcement) number of "CN206902034U," which discloses a clip for liquid crystal glass etching process, comprising a base, a crossbeam, an upper slider, and a lower slider. The base is welded with a plurality of uprights, and the uprights are evenly spaced. Four crossbeams are fixed to the uprights by bolts. The crossbeams include an upper crossbeam and a lower crossbeam, wherein each of the upper and lower crossbeams has two crossbeams. The upper and lower crossbeams each have a fixing bar at the bottom, which is fixedly connected to the uprights and has a plurality of fixing grooves evenly spaced thereon. An upper slider is slidably mounted on the upper crossbeam, and a lower slider is slidably mounted on the lower crossbeam. The present invention ensures that the upper and lower sliders are easily adjustable by providing the upper and lower sliders. Furthermore, when the upper and lower sliders need to be fixed, the upper and lower sliders can be kept stable, thereby preventing the etched liquid crystal glass from tipping over. The structure is simple and practical. However, the technique does not address the technical problems and technical solutions of the present application. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0006] The utility model is a large-size glass spray etching limit clamp, comprising a clamp body, a slotted portion provided on one side of the clamp body, an upper clamping tooth provided at the upper end of the slotted portion extending downward, the upper clamping tooth being a conical structure, and the end portion of the upper clamping tooth being a convex arc surface structure, and a lower clamping tooth provided at the lower end of the slotted portion extending upward, the lower clamping tooth being a conical structure, and the end portion of the lower clamping tooth being a convex arc surface structure.

[0007] A clamping gap is formed between the upper clamping tooth end and the lower clamping tooth end.

[0008] The slotted portion is arranged at the front of the clip body, and the connecting hole is arranged at the rear of the clip body.

[0009] The limiting surface at the bottom of the slotted portion is a concave arc structure.

[0010] The clip body comprises a left clip body and a right clip body, and the left clip body 7 and the right clip body are symmetrically arranged.

[0011] The clip body is provided with an opening.

[0012] The clamp body is connected to the spray carrier via bolts passing through the connection holes.

[0013] The opening of the clamp body is sleeved on the positioning rod on the spray carrier.

[0014] The left side clamp body is connected to the left side of the spray carrier by means of bolts passing through the connection holes, and the right side clamp body is connected to the right side of the spray carrier by means of bolts passing through the connection holes.

[0015] The technical solution of this utility model is adopted, and the working principle and beneficial effects are as follows:

[0016] The large-size glass spray etching limit clamp described in the present invention, when the structure is set, a clamp body is made, and the clamp body needs to be installed on the spray carrier, and the clamp body is provided with multiple on the left side of the spray carrier, multiple on the right side, multiple on the front side, and multiple on the rear side, that is, a group of clamp assemblies is formed, and this group of clamp assemblies can clamp a piece of large-size glass. The spray carrier is provided with multiple groups of clamp assemblies according to the gap from top to bottom, so that multiple pieces of large-size glass can be realized. The clamp body on either side can be easily disassembled, so as to facilitate the placement of large-size glass that needs to be sprayed or the removal of large-size glass that has been sprayed. When the large-size glass is clamped in the clamp body, because the upper end of the slotted portion of the clamp body is provided with an upper clamping tooth extending downward, and the lower end of the slotted portion is provided with a lower clamping tooth extending upward, the large-size glass that needs to be clamped is located between the corresponding upper and lower clamping teeth, and the end face of the large-size glass is against the bottom of the slotted portion 2, thereby realizing reliable limiting of the large-size glass, reliable clamping during the spraying process, and increasing the contact area of ​​the glass, thereby avoiding breakage due to force impact during the spraying process.

[0022] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.

[0023] As attached Figure 1 -Attached Figure 3As shown, the present invention is a large-scale glass spray etching limit clamp, comprising a clamp body 1, a slotted portion 2 provided on one side of the clamp body 1, and an upper locking tooth 3 extending downward from the upper end of the slotted portion 2. The upper locking tooth 3 has a conical structure, and the upper end of the upper locking tooth 3 has a convex arc surface structure. The lower end of the slotted portion 2 is provided with a lower locking tooth 4 extending upward. The lower locking tooth 4 has a conical structure, and the lower end of the lower locking tooth 4 has a convex arc surface structure. The above structure addresses the shortcomings of the existing technology and provides an improved technical solution. When the structure is set up, a clamp body 1 is made, and the clamp body 1 needs to be installed on the spray carrier, and multiple clamp bodies are set on the left side of the spray carrier, multiple right side, front side, and rear side, that is, a group of clamp assemblies are formed. This group of clamp assemblies can clamp a piece of large-size glass. The spray carrier is provided with multiple groups of clamp assemblies according to the gap from top to bottom, so that multiple pieces of large-size glass can be realized. The clamp body on any side can be easily disassembled, so as to facilitate the placement of large-size glass that needs to be sprayed or the removal of large-size glass that has completed spraying. When the large-size glass is clamped in the clamp body, because the upper end of the slotted portion 2 of the clamp body 1 is provided with an upper clamping tooth 3 extending downward, and the lower end of the slotted portion 2 is provided with a lower clamping tooth 4 extending upward, the large-size glass to be clamped is located between the corresponding upper and lower clamping teeth, and the end face of the large-size glass is against the bottom of the slotted portion 2, thereby realizing reliable limitation of the large-size glass, reliable clamping during the spraying process, and increasing the contact area of ​​the glass, thereby avoiding breakage due to force impact during the spraying process. The large-size glass spray etching limit clamp described in the utility model has a simple structure. By improving the limit clamp structure, the problem of small contact area between the edge of the glass and the limit clamp when clamping large-size glass is solved, and the contact area is increased, that is, the force-bearing area of ​​the glass clamping is increased, thereby reducing the damage rate.

[0024] The end of the upper latching tooth 3 and the end of the lower latching tooth 4 are separated by a latching gap 9. With the above structure, when large-sized glass is clamped, the glass is located in the latching gap 9, thereby achieving upper and lower position limiting.

[0025] The slotted portion 2 is provided at the front of the clamp body 1, and a connecting hole 5 is provided at the rear of the clamp body 1. In the above structure, the connecting hole is used for bolts to pass through and fix to the spray carrier.

[0026] The limiting surface 6 at the bottom of the slotted portion 2 is a concave arc-shaped structure. With the above structure, when large-sized glass is clamped, the end edge of the glass rests on the limiting surface 6 to achieve side limiting.

[0027] The clamping body 1 comprises a left-side clamping body 7 and a right-side clamping body 8, arranged symmetrically. With this structure, the left and right clamping bodies 7 and 8 are symmetrically arranged, so the limiting surfaces 6 of the left and right clamping bodies 7 and 8 cooperate to limit the glass from the left and right sides. Furthermore, front and rear clamping bodies can also be installed on the front and right sides of the spray vehicle, respectively, to limit the glass from four horizontal directions. Multiple sets of upper and lower locking teeth are added to achieve upper and lower limit.

[0028] The clamp body 1 is connected to the spray carrier by bolts passing through the connection holes 5. The above structure facilitates the connection between the clamp body and the spray carrier by bolts and is easy to disassemble.

[0029] The clamp body 1 is provided with an opening 10. The opening 10 of the clamp body 1 is mounted on a positioning rod on the spray vehicle. The above structure reliably positions the clamp body on the spray vehicle. During the spraying process of the spray vehicle, the clamp body reliably holds the glass in place.

[0030] The left clamp body 7 is connected to the left side of the spray carrier by a bolt passing through the connection hole 5, and the right clamp body 8 is connected to the right side of the spray carrier by a bolt passing through the connection hole 5. In the above structure, each clamp body is fixedly connected to the spray carrier.

[0031] The large-size glass spray etching limit clamp described in the present invention is structured to make a clamp body 1, which needs to be installed on the spray carrier, and multiple clamp bodies are set on the left side of the spray carrier, multiple on the right side, multiple on the front side, and multiple on the back side, forming a group of clamp components. This group of clamp components can clamp a piece of large-size glass. The spray carrier is provided with multiple groups of clamp components according to the gap from top to bottom, so that multiple pieces of large-size glass can be realized. The clamp body on any side can be easily disassembled, so that it is convenient to put in the glass that needs to be sprayed. When large-sized glass or large-sized glass that has been taken out for spraying is clamped in the clamp body, because the upper end of the slotted portion 2 of the clamp body 1 is provided with an upper clamping tooth 3 extending downward, and the lower end of the slotted portion 2 is provided with a lower clamping tooth 4 extending upward, the large-sized glass to be clamped is located between the corresponding upper and lower clamping teeth, and the end face of the large-sized glass is against the bottom of the slotted portion 2, thereby realizing reliable limitation of the large-sized glass, reliably realizing glass clamping during the spraying process, and increasing the contact area of ​​the glass, thereby avoiding breakage due to force impact during the spraying process.

[0032] The above is an exemplary description of the present invention 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 scope of protection of the present invention.
