Description

Technical Field

[0001] The present application relates to the technical field of substrate glass production and manufacturing, and in particular to a device for pushing and breaking semi-finished TFT substrate glass. Background Art

[0002] TFT substrate glass is a kind of display device substrate glass with a wide range of applications. At present, the production process of semi-finished TFT substrate glass is mostly an overflow pull-down method, and the specific process is as follows: First, the glass liquid flows vertically from the hot end to form a glass plate; then, a horizontal line is drawn on the glass plate, usually using a cross-cutting machine; then, the workpiece (such as a suction cup assembly, etc.) is brought to the line by a robot, and flows down with the glass, keeping relatively still, and fixing the glass using vacuum adsorption technology; finally, the suction cup assembly is dragged to one side to complete the breaking action, so that the glass plate is broken and split at the line. For example, Chinese Patent 202110529824.8 discloses a substrate glass longitudinal cutting and breaking machine and its suction cup frame.

[0003] However, in the existing breaking process, the speed fluctuation of the glass flowing downward may cause the robot to be unable to be completely still relative to the glass. This speed mismatch will cause precision deviation during breaking, resulting in poor force direction of the suction cup assembly, affecting the breaking effect. For example, when the robot's falling speed is higher than the glass's falling speed, the suction cup assembly will pull the glass downward; when the robot's falling speed is lower than the glass's falling speed, the suction cup assembly will bend the glass upward, ultimately resulting in poor breaking. In addition, such poor breaking will also be accompanied by the generation of a large amount of dust, which may adhere to the glass and have an adverse effect on the quality of the glass.

[0034] refer to Figures 1 to 3 As shown, the present application discloses a device for pushing and breaking a semi-finished TFT substrate glass, the device comprising: an anvil assembly, the anvil assembly comprising an anvil bar 2. A pushing assembly, the pushing assembly comprising: a pushing mechanism 4 and a pushing bar 1. The pushing bar 1 is arranged at a position close to the anvil bar 2, and is relatively fixed in a vertical position with the anvil bar 2. The pushing mechanism 4 is connected to the pushing bar 1, and drives the pushing bar 1 to reciprocate perpendicularly to the semi-finished TFT substrate glass 5. A moving assembly, the moving assembly is used to install the anvil assembly and the pushing assembly, and drive the anvil assembly and the pushing assembly to reciprocate along the semi-finished TFT substrate glass 5.

[0035] Through the above design, the embodiment of the present application sets a push strip 1 at a position close to the chopping board strip 2, and the chopping board strip 2 and the push strip 1 are movably installed through a moving component, so that the chopping board strip 2 and the push strip 1 can be moved promptly and quickly after the glass is scored, so that the push strip 1 is aligned with the scoring position of the glass, and then the glass is quickly broken by vertically pushing the glass, which effectively avoids the speed synchronization problem caused by the robot breaking after adsorption by the adsorption component, improves the accuracy of glass breaking, reduces the phenomenon of poor breaking and the dust generated thereby, and improves the quality and process accuracy of glass products.

[0036] In some embodiments of the present application, Figures 1 to 3 As shown, the push bar 1 and the anvil bar 2 are arranged on the same side of the semi-finished TFT substrate glass 5. Figure 2As shown in the side view schematic diagram, during the falling process of the semi-finished TFT substrate glass 5, according to the required cutting size of the substrate glass, at a specific position, the cutting knife 6 of the cross-cutting machine will approach the semi-finished TFT substrate glass 5, and move laterally along the direction of the anvil strip 2 under the support of the anvil strip 2, so as to draw a cutting line for the semi-finished TFT substrate glass 5, thereby preparing for the cutting and breaking process. Since the vertical position of the anvil strip 2 relative to the push strip 1 is fixed, the distance between the push strip 1 and the drawn cutting line is fixed and known. Therefore, when the marking is completed, the embodiment of the present application can quickly move the anvil strip 2 and the push strip 1 through the moving component (movable mounting plate 3), so that the push strip 1 is aligned with the cutting line, and vertically push the semi-finished TFT substrate glass 5 under the driving action of the push mechanism 4, so that it breaks at the cutting line, and realizes a timely and rapid breaking operation. Since the moving distance of the pushing bar 1 in this process is small and the pushing action delay is small, it is less susceptible to the fluctuation of the falling speed of the semi-finished TFT substrate glass 5. Therefore, the breaking accuracy is high and the action is accurate, the consistency is good, and it is not easy to break poorly. At the same time, the collision and impact of the glass during the breaking process can be reduced, thereby reducing the generation of dust and preventing dust from adhering to the high-temperature glass surface, affecting the glass quality or even scrapping the glass products.

[0037] Or, in some other embodiments of the present application, such as Figure 4 As shown, the push bar 1 and the anvil bar 2 are arranged on opposite sides of the semi-finished TFT substrate glass 5. By arranging the push bar 1 on the opposite side of the anvil bar 2, the push bar 1 can be pushed and broken on the cut surface of the semi-finished TFT substrate glass 5, so that the breaking is easier and more labor-saving. At the same time, the anvil bar 2 can also provide reverse support force for the pushing action, so as to prevent the semi-finished TFT substrate glass 5 from shaking and affecting the breaking effect.

[0038] In some embodiments of the present application, when the push bar 1 and the anvil bar 2 are arranged on opposite sides of the TFT semi-finished substrate glass 5, the push bar 1 and the anvil bar 2 are horizontally staggered, and the push bar 1 is located under the anvil bar 2, so that installation, maintenance and use are more convenient.

[0039] In some embodiments of the present application, Figures 1 to 4 As shown, the side of the pushing bar 1 facing the semi-finished TFT substrate glass 5 is sharp-angled, so that the cutting line can be aligned more accurately and the pushing action can be performed accurately in position to improve the breaking and segmentation accuracy.

[0040] In some embodiments of the present application, reference Figure 3As shown, the push mechanism 4 is arranged behind the push bar 1, and the push mechanism 4 can be any type of driving mechanism that can realize pushing, such as a cylinder or a servo motor. In some embodiments of the present application, the push mechanism 4 is a cylinder, and the output end of the cylinder is connected to the push bar 1 to drive the push bar 1 to reciprocate perpendicular to the TFT semi-finished substrate glass 5. Since the cylinder uses an air source as a power source, it is safer and more reliable to use in a high temperature environment, and since the push stroke required by the push bar 1 is very short, the response speed of the cylinder can meet the requirements, which is more cost-effective than a servo motor.

[0041] In some embodiments of the present application, Figures 1 to 4 As shown, the moving assembly includes a mounting plate 3, anvil strip 2 and push strip 1 are connected to the mounting plate 3, and the mounting plate 3 can move vertically up and down to drive the anvil strip 2 and push strip 1 to reciprocate along the surface of the semi-finished TFT substrate glass 5. Figure 1 and Figure 3 As shown, the mounting plate 3 is a group of two pieces, which are respectively connected to the two ends of the chopping board strip 2 and the pushing strip 1. The chopping board strip 2 and the pushing strip 1 are fixed in position with the mounting plate 3 and move up and down with the mounting plate 3. In addition, the pushing strip 1 can also move in the direction perpendicular to the mounting plate 3 under the lateral pushing action of the pushing mechanism 4 to realize the pushing and breaking action of the semi-finished TFT substrate glass 5.

[0042] In some embodiments of the present application, the mounting plate 3 can be installed vertically and movably up and down on a cross-cutting machine for scoring semi-finished TFT glass substrates, that is, the anvil assembly, the push assembly and the moving assembly of the embodiments of the present application can be modified and used as part of the cross-cutting machine, so as to be installed on the cross-cutting machine to realize equipment integration, and finally cooperate with the cutting knife 6 of the cross-cutting machine to collaboratively realize the scoring and breaking of the glass plate, thereby improving the quality and process accuracy of the processed glass products.

[0043] In some embodiments of the present application, the mobile assembly is installed on the crosscutting machine by slide rail installation. A vertical slide rail is provided on the crosscutting machine, and the mounting plate 3 is installed on the crosscutting machine through the vertical slide rail to drive the cutting board assembly and the push assembly to move in the vertical direction.

[0044] In some embodiments of the present application, the TFT semi-finished substrate glass pushing and breaking device further includes a negative pressure component. At the same time, a plurality of dust suction holes are provided on the anvil strip 2 and / or the pushing strip 1, and the dust suction holes are connected to the negative pressure component. The dust and debris generated by the breaking action are sucked into the dust collector through the negative pressure of the negative pressure component to ensure the quality of the glass product. Among them, the dust suction holes are distributed along the movement trajectory of the pushing strip 1 to conveniently suck in the dust and debris generated by the pushing action.

[0045] In some embodiments of the present application, the anvil strip 2 and the push strip 1 are made of high temperature resistant materials and can contact the high temperature TFT semi-finished substrate glass 5 without being easily worn. For example, metal materials such as aluminum can be used.
