Description

Technical Field

[0001] The utility model belongs to the technical field of high-generation substrate glass, and particularly relates to a substrate glass suspension transmission stabilization mechanism. Background Art

[0002] Substrate glass is a fundamental component of liquid crystal display devices and a key material in the flat panel display industry. Stringent requirements are met for defects (bubbles, stones, Perkin, glass powder, dirt, scratches, cracks, etc.) on substrate glass. Glass defects directly impact the processing and display performance of LCD panels. Therefore, glass defect inspection is crucial in the processing of semi-finished substrate glass products, and accuracy is crucial. Accurate inspection of glass defects allows for timely feedback to the hot-end kiln and molding processes for process countermeasures. Furthermore, semi-finished substrate glass with severe defects is detected by inspection machines and discarded from the semi-finished process, preventing it from entering the cold-end post-processing process. This improves the post-processing yield and reduces processing costs. Currently, the domestic production process for semi-finished glass substrates relies on manual inspection machines. These machines operate by holding a suspended semi-finished glass substrate within a manual inspection machine. Arms on either side of the machine clamp the glass substrate. LED lights within the arms illuminate the glass substrate, and workers visually observe defects to determine their type and size. This results in a high rate of misjudgments and incorrect identifications, which can mislead hot-end furnace process strategies, reduce yield rates on cold-end post-processing lines, and increase processing costs. Therefore, manual inspection has been abandoned in the G8.5 semi-finished glass substrate production process, with automated in-line inspection machines adopted to improve defect detection accuracy. However, the CCD camera in the automated inspection machine requires that the Z-direction (perpendicular to the glass flow direction) swing of the substrate glass be controlled within 10 mm during the camera capture process. Furthermore, the glass does not stop at the automated inspection machine, flowing directly through the machine. However, in practice, the Z-direction swing of the substrate glass can be significantly greater than 10 mm, preventing the CCD camera from accurately capturing images. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above-mentioned problem that the swing drift of the substrate glass is too large during the self-inspection process of the substrate glass moving through the automatic inspection machine, and provide a substrate glass suspension transmission stabilization mechanism.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A substrate glass suspension transmission stabilization mechanism, wherein the stabilization mechanism includes a first stabilization mechanism and a second stabilization mechanism, the first stabilization mechanism and the second stabilization mechanism are arranged in front of and behind each other; the first stabilization mechanism and the second stabilization mechanism are each formed by connecting two stabilization units; the stabilization unit includes a base plate, a linear guide rail, a first slider, a second slider, a first cylinder and a second cylinder, the first cylinder, the second cylinder and the linear guide rail are respectively fixed to the base plate, the first slider and the second slider are respectively embedded in the upper and lower ends of the linear guide rail, the piston end of the first cylinder is connected and fixed to the first slider, and the piston end of the second cylinder is connected and fixed to the second slider.

[0006] The first slider and the second slider follow the telescopic ends of the first cylinder and the second cylinder and slide up and down along the linear guide rail.

[0007] The two stabilizing units are connected and fixed by a long rod, and the two ends of the long rod are connected to the bottom plates on the two stabilizing units.

[0008] A transverse stabilizing mechanism arm is also provided between the two stabilizing units, and the stabilizing mechanism arm and the long rod jointly connect the two stabilizing units together.

[0009] The stabilizing mechanism arm comprises a stabilizing mechanism upper arm and a stabilizing mechanism lower arm, the stabilizing mechanism upper arm and the stabilizing mechanism lower arm are parallel, the stabilizing mechanism upper arm is connected to the first slider, and the stabilizing mechanism lower arm is connected to the second slider.

[0010] A plurality of guide rollers are installed on the upper arm of the stabilizing mechanism and the lower arm of the stabilizing mechanism, and the guide rollers of the upper arm and the lower arm of the stabilizing mechanism constitute the moving surface of the bottom edge of the glass.

[0011] The guide rollers are evenly arranged in a row, bearings are embedded in the guide rollers, and the guide rollers rotate around the bearings.

[0012] The guide rollers are made of UPE material which will not cause stress changes in the glass when it collides with the glass.

[0013] The heights of the first stabilizing mechanism bottom plate and the second stabilizing mechanism bottom plate can be adjusted up and down by 100 mm, and are compatible with different types of substrate glass.

[0014] Several CCD cameras and LED light sources of the inspection machine are vertically distributed from bottom to top on the outer sides of both sides of the second stabilizing mechanism to complete the online inspection of the substrate glass.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model discloses a substrate glass suspension transmission stabilization mechanism, in which the stabilization mechanism arms, bottom plates, cylinders and sliders of the first stabilization mechanism and the second stabilization mechanism are symmetrically arranged, and have a simple structure. The cylinder is a piston that extends and retracts up and down to drive the stabilization mechanism arms to open and close, and the stabilization mechanism arms are provided with rollers that are evenly arranged in a row. After the glass enters the stabilization mechanism, the rollers are driven to rotate around bearings, and the bottom edge of the substrate glass is clamped by the guide rollers on both sides of the arms, thereby greatly reducing the swing drift of the substrate glass in the Z direction, so that the swing amount of the glass in the Z direction is stabilized within 10 mm, meeting the requirements of the on-line inspection of the inspection machine; the cylinder piston extends and retracts to drive the stabilization mechanism arms to open and close on the linear guide rail, and the width of the gap between the stabilization mechanism arms can be changed according to the actual situation of the substrate glass, which can effectively reduce the phenomenon of excessive swing drift of the substrate glass during movement.

[0017] Furthermore, the cylinders on the bottom plate of the stabilizing mechanism are arranged relatively up and down to change the gap width between the arms of the stabilizing mechanism to adjust the gap between the arms of the stabilizing mechanism in real time when the glass passes through, effectively reducing the swing amplitude of the substrate glass during movement and improving stability.

[0018] Furthermore, the guide rollers are evenly arranged in a row, simplifying the structural complexity. At the same time, bearings are embedded inside the rollers, and the rollers rotate around the bearings. The glass contacts the rollers during movement, causing the rollers to rotate, thereby preventing the substrate glass from contacting and colliding with the rollers, which may cause changes in the glass stress.

[0019] Furthermore, the guide roller is made of UPE material, so that when the substrate glass contacts the guide roller, contact collision is prevented to cause changes in glass stress.

[0020] Furthermore, the heights of the first stabilizing mechanism bottom plate and the second stabilizing mechanism bottom plate can be adjusted up and down by 100 mm, and the longitudinal height difference between G8.5 and G8.6 is the same as 100 mm. The adjustable height corresponds to the height difference between the two substrate glasses, achieving compatibility with different types of substrate glasses.

[0021] Furthermore, CCD cameras and LED light sources of the inspection machine are vertically distributed on both sides of the second stabilization mechanism, which realizes online inspection during the transmission process of the substrate glass and improves the accuracy of substrate glass defect inspection.

DETAILED DESCRIPTION

[0027] In order to further understand the content of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments are only for explanation of the present invention and are not intended to limit the present invention.

[0028] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The substrate glass suspension transmission stabilization mechanism of the present invention consists of a first stabilization mechanism 1 and a second stabilization mechanism 2. Based on the lateral dimensions, longitudinal dimensions and thickness of two high-generation substrate glass types, G8.5 and G8.6, the first stabilization mechanism 1 and the second stabilization mechanism 2 are compatible with both substrate glass sizes.

[0029] The first stabilizing mechanism 1 and the second stabilizing mechanism 2 are arranged front to back. Both stabilizing mechanisms are connected by two stabilizing units 3. A long rod 12 is connected and fixed between the two stabilizing units 3. The stabilizing unit 3 is composed of a base plate 4, a linear guide 5, a first slider 6, a second slider 7, a first cylinder 8 and a second cylinder 9. Figure 2 and Figure 3 As shown, the base plate 4 is arranged at the bottom of the stabilizing unit 3, the first cylinder 8, the second cylinder 9, and the linear guide 5 are respectively fixed on the base plate 4, the first slider 6 is embedded in the upper end of the linear guide 5, and the second slider 7 is embedded in the lower end of the linear guide 5. The piston end of the first cylinder 8 is connected to the first slider 6, and the piston end of the second cylinder 9 is connected to the second slider 7. The first slider 6 and the second slider 7 move in opening and closing on the linear guide 5 following the extension and contraction of the first cylinder 8 and the second cylinder 9; as shown Figure 1As shown, the stabilizing mechanism is further provided with a stabilizing mechanism arm 13, which is divided into a stabilizing mechanism upper arm 14 and a stabilizing mechanism lower arm 15. The stabilizing mechanism upper arm 14 is fixedly connected to the first slider 6, and the stabilizing mechanism lower arm 15 is fixedly connected to the second slider 7. The upper and lower arms of the stabilizing mechanism arm 13 follow the movement of the first slider 6 and the second slider 7 on the linear guide rail 5 to change the distance between the two arms; a plurality of guide rollers 10 are evenly distributed on the upper and lower arms of the stabilizing mechanism arm 13, and the plurality of guide rollers 10 are arranged in a row. The two rows of guide rollers 10 form a plane for the bottom edge of the glass to move. The bottom edge of the substrate glass passes through the gap between the upper and lower arms of the stabilizing mechanism arm 13. The center of the guide roller 10 is inlaid with a bearing 11, and the guide roller 10 rolls along the bearing 11; the upper and lower arms of the stabilizing mechanism arm 13 are respectively connected to the sliders on the two stabilizing units 3 of the stabilizing mechanism, the upper arm 14 of the stabilizing mechanism is connected to the first slider 6, and the lower arm 15 of the stabilizing mechanism is connected to the second slider 7. The two stabilizing units 3 are further connected together through the stabilizing mechanism arm 13 and the long rod 12.

[0030] The first stabilizing mechanism 1 and the second stabilizing mechanism 2 have the same structure, and both are composed of two stabilizing units 3 connected and fixed by a long rod 12 .

[0031] A glass suspension transmission stabilization mechanism and its implementation method:

[0032] First, the base plates 4 of the first stabilizing mechanism 1 and the second stabilizing mechanism 2 are fixed to the ground with legs. The base plates 4 of the two stabilizing mechanisms can be adjusted up and down by 100 mm, which can be compatible with both G8.5 and G8.6 substrate glasses. Then, the two base plates 4 are connected and fixed with a long rod 12. The first cylinder 8, the second cylinder 9 and the linear guide 5 are fixed on the base plates 4 of the two stabilizing mechanisms. The first slider 6 and the second slider 7 are embedded at the upper and lower ends of the linear guide 5. The piston end of the first cylinder 8 is connected to one end of the first slider 6, and the piston end of the second cylinder 9 is connected to the end of the second slider 7. At one end, the first cylinder 8 and the second cylinder 9 are arranged opposite to each other, and the left and right ends of the upper arm 14 of the stabilizing mechanism arm 13 are connected to the first slider 6 on the two stabilizing units 3 of the stabilizing mechanism, and then the left and right ends of the lower arm 15 of the stabilizing mechanism arm 13 are connected to the second slider 7 on the two stabilizing units 3 of the stabilizing mechanism, so that the stabilizing mechanism arm 13 connects the two stabilizing units 3 together, and guide rollers 10 are evenly distributed in a row on the upper and lower arms of the stabilizing mechanism arm 13. Bearings 11 are embedded in the guide rollers 10, and the guide rollers 10 rotate around the bearings 11.

[0033] The guide roller 10 is made of UPE material. When the bottom edge of the suspended substrate glass passes through the gap between the upper and lower arms of the stabilizing mechanism, it comes into contact with the guide roller 10, causing the guide roller 10 to rotate around the bearing 11. This prevents the substrate glass from contacting and colliding with the guide roller 10, which may cause changes in the glass stress.

[0034] After installation, the glass stabilization mechanism is controlled by the PLC program of the suspension transmission device. The substrate glass first needs to pass through the first stabilization mechanism 1. Before the suspended substrate glass enters the gap between the upper and lower arms of the stabilization mechanism arm 13, the swing drift of the glass in the Z direction is about 20mm-50mm. Therefore, the first cylinder 8 and the second cylinder 9 of the first stabilization mechanism 1 are in the extended state. At this time, the gap between the upper arm 14 and the lower arm 15 of the stabilization mechanism arm 13 of the first stabilization mechanism is 120mm. When the bottom edge of the suspended substrate glass enters the stabilization mechanism arm When the length of the gap between the first and second slides 13 reaches 500 mm, the first cylinder 8 and the second cylinder 9 on the bottom plate 4 of the stabilizing unit 3 automatically contract, causing the first slide 6 and the second slide 7 to move relative to each other on the linear guide rail 5. The upper arm 14 and the lower arm 15 of the stabilizing mechanism connected to the first and second slides 6 and 7 also move relative to each other. At this time, the gap between the upper and lower arms of the stabilizing mechanism arm 13 of the first stabilizing mechanism 1 changes from 120 mm to 10 mm. At the same time, the bottom edge of the substrate glass continues to move forward in the 10 mm gap along with the rotation of the guide roller 10 and the bearing 11.

[0035] The glass substrate then smoothly enters the second stabilization mechanism 2. Because the first and second cylinders 8 and 9 in the stabilization unit 3 of the second stabilization mechanism are retracted, the upper and lower stabilization mechanisms 14 and 15 connected to the first and second slides 6 and 7 are also retracted. The gap between the upper and lower arms of the stabilization mechanism 13 is 8 mm, allowing the bottom edge of the suspended glass substrate to pass smoothly through the 8 mm gap between the upper and lower arms of the stabilization mechanism 13. This ensures that the Z-direction swing drift of the glass substrate is stable within 10 mm, meeting the requirements of the inspection machine's online inspection. Because the inspection machine's CCD camera and LED light source are vertically arranged on both sides of the second stabilization mechanism 2 from bottom to top, the inspection machine simultaneously completes the defect inspection of the entire glass substrate as the glass substrate smoothly passes through the gap between the stabilization mechanism arms 13 of the second stabilization mechanism 2. After one cycle is completed, the machine waits for the next glass substrate to enter and repeats the above steps.

[0036] When, under abnormal circumstances, individual substrate glass breaks during the suspension transmission process and falls into the gap between the stabilizing mechanism arms 13 of the second stabilizing mechanism 2, the operator manually controls the first cylinder 8 and the second cylinder 9 of the second stabilizing mechanism 2 to extend the pistons, and the gap spacing of the stabilizing mechanism arms 13 of the second stabilizing mechanism 2 becomes 120 mm, which is convenient for manual removal of broken glass. After the broken glass is removed, the operator manually controls the pistons of the first cylinder 8 and the second cylinder 9 to retract, and the gap spacing of the stabilizing mechanism arms 13 of the second stabilizing mechanism 2 is restored to 8 mm.

[0037] When it is necessary to switch from G8.5 substrate glass to G8.6 substrate glass, the supporting legs of the bottom plate 4 of the first stabilizing mechanism 1 and the second stabilizing mechanism 2 can be adjusted downward by 100 mm.

[0038] The following table shows the main parameters of G8.5 / G8.6 semi-finished substrate glass.
