Abstract
Description
Technical Field
[0001] This utility model belongs to the field of substrate glass manufacturing technology, specifically relating to a substrate glass transverse cutting and shaking control device. Background Technology
[0002] Overflow pull-down method is one of the main methods for producing liquid crystal glass substrates. This method involves mixing raw materials in a specific ratio evenly and then heating them in a tank furnace to a molten state. The mixture is then transported through a platinum pipe to the overflow brick in the muffle furnace.
[0003] When the overflow brick is full, the molten glass will overflow along both sides of the overflow brick to the inclined wall. At the bottom of the overflow brick, the two glass materials merge to form a glass plate. By being pulled downward by the traction device, a single glass ribbon is formed. The glass ribbon will have a certain bow shape in the annealing furnace due to its own weight, annealing and the clamping of the short rollers at the edges.
[0004] After the cross-cutting blade wheel cuts the glass using the B-side anvil strip, the glass breaking robot is affected by the glass's arc shape at the moment of breaking the glass. In addition, the extension and retraction of the near and far ends of the A-side anvil strip cannot be controlled independently, so the large gap between the A-side anvil strip and the B-side anvil strip will cause large shaking. The C-shaped change of the glass edge will also increase the loss of the cross-cutting, which can easily cause the glass to break and thus cause safety risks. Utility Model Content
[0005] The purpose of this invention is to overcome the problem that the edges are more difficult to break and more prone to damage when breaking a substrate glass, and to propose a substrate glass transverse cutting and breaking shaking control device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A substrate glass transverse cutting and shaking control device includes an A-side anvil strip and a B-side anvil strip, which are arranged opposite to each other. The substrate glass is placed between the A-side anvil strip and the B-side anvil strip. The edges of the A-side anvil strip and the edges of the B-side anvil strip are in close contact with the substrate glass, while the middle part of the A-side anvil strip is detached from the middle part of the B-side anvil strip.
[0008] Furthermore, the two ends of the A-side cutting board holder are fixed to the support profile plate, and the stroke of the support profile plate is controlled by the cylinder moving forward and backward.
[0009] Furthermore, a gap is provided between the A-side cutting board strip and the B-side cutting board strip.
[0010] Furthermore, the gap between the A-side cutting board strip and the B-side cutting board strip includes an edge gap and a middle gap.
[0011] Furthermore, the intermediate gap is 10mm.
[0012] Furthermore, the edge gap is 2-3 mm.
[0013] Furthermore, the A-side cutting board strip is installed in the groove of the A-side cutting board holder.
[0014] Furthermore, the B-side cutting board strip is installed in the groove of the B-side cutting board holder.
[0015] Furthermore, the two ends of the A-side cutting board holder protrude from the middle of the A-side cutting board holder.
[0016] Furthermore, the two ends of the A-side cutting board holder protrude 8-10mm beyond the middle of the A-side cutting board holder.
[0017] Compared with the prior art, the present invention has the following beneficial technical effects:
[0018] This invention proposes a substrate glass cross-cutting and breaking plate wobbling control device. By changing the shape of the A-side anvil rack, it can easily control the gap between the A and B sides anvils to the ideal position, avoiding the influence of the glass's bow shape. This is beneficial for breaking the glass, especially in the later stages of muffle furnace use where the glass edges gradually deteriorate, providing excellent assistance. The goal can be achieved simply by modifying the grooved holes on the A-side anvil rack of existing equipment. This can be accomplished by changing the shape of the cylindrical groove on the anvil rack, making the operation relatively simple, inexpensive, and highly practical. It avoids the influence of the glass's central bow shape and controls the glass edge gap to an ideal state. During breaking, the glass edge plate can be controlled by adjusting the gap between the A and B sides anvils to control the instantaneous wobbling of the glass plate. This also ensures that the effective area of the glass is protected from scratches, stabilizes the bow shape, thereby reducing cross-cutting and breaking losses and minimizing glass wobbling. It also improves the control of glass dust and thermal contamination.
[0019] By adjusting the existing cylinder stroke, the gap between the AB surfaces can be controlled, so that the edge gap is controlled at 2-3mm and the middle gap is controlled at 10mm. This not only allows the middle part to detach from the glass without causing scratches or affecting the bow shape, but also allows the edge to be close to the glass at the edge-pulling machine's indentation, reducing shaking and loss during the breaking process, and making it more conducive to the cutting wheel.
[0020] By controlling the gap between the A and B anvil strips, the variation in the arc shape can be stabilized. This is especially important because the glass edges are thicker than the center, and the edge-pulling machine's indentations make breaking the glass more difficult and prone to breakage. This invention solves these problems. By adjusting the cylinder stroke of the A-side anvil holder, the gap between the A and B sides can be freely controlled according to the glass's condition. This achieves the goal of controlling transverse cutting losses and reducing glass wobble. Attached Figure Description

[0029] Example 1
[0030] Glass breaking is a crucial process in glass production, involving the cutting, shaping, and separation of glass. Here is a detailed explanation of glass breaking in glass production: Glass breaking mainly refers to the operation of cutting and separating glass sheets or plates to predetermined sizes and shapes using specific equipment and techniques during glass processing. This step is particularly important in the production of flat glass, float glass, and coated glass.
[0031] The breaking roller conveyor includes a transverse breaking roller conveyor and an edge-breaking roller conveyor. The transverse breaking roller conveyor breaks the glass strip with transverse cuts along the cuts. When the transverse cuts reach the breaking roller, the control computer sends a signal to activate the cylinder that lifts the breaking roller. The breaking roller then transversely breaks the glass strip along the cuts, separating it into glass sheets. The edge-breaking roller conveyor breaks off the two natural edges of the glass sheet with longitudinal cuts. Currently, two common edge-breaking methods are used: one method involves making only one cut on each of the two natural edges, using one section of edge-breaking roller conveyor to break off both edges at once; the other method involves making two cuts on each of the two natural edges, using two sections of edge-breaking roller conveyor for two separate edge-breaking operations. The edge-breaking pressure roller and the worktable can be mounted on a movable edge-breaking roller conveyor frame.
[0032] The glass slicing and conveying system includes a belt-driven slicing conveyor and a negative pressure suction cup continuous slicing machine. The belt-driven slicing conveyor vertically distributes glass sheets from the side of the main conveyor rollers to the branch lines. This type of slicing conveyor is generally suitable for slicing large and medium-sized glass sheets or grouping small sheets. The negative pressure suction cup continuous slicing machine continuously and rapidly distributes small glass sheets, which have already been longitudinally broken into several pieces on the main conveyor rollers, from the main conveyor rollers for stacking or boxing.
[0033] The glass breaking process includes surface treatment, measurement and marking, cutting and grooving, breaking / edge shaping, and post-processing. Specifically: Surface treatment: Before breaking or edging, the glass surface needs to be polished and cleaned to ensure smooth and even edges. Measurement and marking: Measurements are made and marked on the glass sheet or plate according to the required dimensions, shapes, and angles. Cutting and grooving: Grooves are cut using a glass cutter or electronic heating cutter, generally to about half the glass thickness. Breaking / edge shaping: Edges are broken using a breaking machine, edge-breaking machine, or manual edge-breaking tool to shape the glass edges. Post-processing: The broken or edged edges are sandblasted or polished to improve surface smoothness and aesthetics.
[0034] See Figure 1 and Figure 2 This embodiment provides a substrate glass transverse cutting and shaking control device, including an A-side cutting board strip 5 and a B-side cutting board strip 2. The A-side cutting board strip 5 and B-side cutting board strip 2 are arranged opposite each other, with the substrate glass placed between them. The edges of the A-side cutting board strip 5 and the B-side cutting board strip 2 are in close contact with the substrate glass, while the middle portions of the A-side cutting board strip 5 and B-side cutting board strip 2 are detached from the substrate glass. Both ends of the A-side cutting board frame 4 are fixed to a support profile plate, and the stroke of the support profile plate is controlled by a cylinder moving forward and backward. A gap is provided between the A-side cutting board strip 5 and the B-side cutting board strip 2. The gap between the A-side cutting board strip 5 and the B-side cutting board strip 2 includes an edge gap and a middle gap. The middle gap is 10mm. The edge gap is 2-3mm. The A-side cutting board strip 5 is installed in a groove in the A-side cutting board frame 4. The B-side cutting board strip 2 is installed in a groove in the B-side cutting board frame 4. The two ends of the cutting board holder 4 on side A protrude from the middle of the cutting board holder 4 on side A. The two ends of the cutting board holder 4 on side A protrude 8-10mm from the middle of the cutting board holder 4 on side A.
[0035] The relative arrangement of the A-side anvil strip 5 and the B-side anvil strip 2 in this embodiment, along with the close contact (edge) and detachment (center) design with the substrate glass, effectively controls the wobbling of the substrate glass during the cross-cutting and splitting process. The close contact at the edges provides necessary support, while the detachment at the center reduces the contact area with the substrate glass, lowering friction and resistance caused by excessive contact, thereby reducing wobbling. The center gap is set to 10mm, and the edge gap is 2-3mm. This gap design ensures sufficient support while avoiding increased friction or substrate glass jamming caused by too small a gap. This design helps maintain the stability and smoothness of the substrate glass during the splitting process. By precisely controlling the gap between the A-side anvil strip 5 and the B-side anvil strip 2, and the protrusion (8-10mm) at both ends of the A-side anvil frame 4 relative to the center, the positional accuracy of the substrate glass during processing can be ensured. This design helps reduce substrate glass damage or increased defect rate due to processing errors. The stroke of the A-side anvil holder 4 is controlled by the forward and backward movement of cylinders at both ends. This design allows the entire device to flexibly adapt to the processing needs of substrate glass of different sizes and specifications. Meanwhile, the A-side anvil strip 5 and the B-side anvil strip 2 are installed in their respective anvil holder slots, facilitating replacement and maintenance. Through this design, the device can improve processing efficiency while ensuring processing quality. Reducing shaking and friction helps to lower energy consumption and processing time, thereby reducing costs and improving overall production efficiency.
[0036] In this embodiment, the shape of the A-side anvil groove is changed from a straight line to one end protruding outwards, 8-10mm more than the middle. After the above changes, when breaking the glass, the glass edge plate can be controlled by controlling the gap between the A and B-side anvil strips to control the instantaneous shaking of the glass plate during breaking. It can also ensure that the effective area of the glass is protected from scratches and stabilize the bow shape, thereby reducing the loss of the glass during cross-cutting and reducing the shaking of the glass. It can also improve the control of glass powder and heat contamination.
