Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal substrate glass production, in particular to a device for measuring the centering distance of short rollers in liquid crystal substrate glass production. Background Technique

[0002] The overflow down-draw method is one of the main methods for flat glass production. It mainly uses the continuously flowing molten glass liquid to overflow on both sides of the refractory chute and converge at the tip of the lower end of the chute to form a glass plate, which is then formed into a glass plate by a traction mechanism. Since the glass surface does not contact any material in this method, thin glass plates with good surface smoothness, flatness, no need for grinding and polishing, and uniform thickness can be produced. During normal production, the glass plates converge into a whole glass plate from the tip of the overflow brick, and form a complete glass plate under the downward pulling force of the edge roller. Then, it is clamped by the traction roller below and undergoes processes such as annealing to form a glass plate product.

[0003] However, in the actual production process, there are differences in the wear amounts of the traction rollers on both sides of the liquid crystal substrate glass. In order to minimize this difference and extend the service life of the traction rollers, the existing technology generally adopts an artificial adjustment method, which not only has low accuracy, relying entirely on the experience of the staff, but also has low efficiency.

Detailed Embodiments

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1-5 The utility model provides a technical solution: a device for measuring the centering distance of short rollers in the production of liquid crystal substrate glass, which consists of a base 1, two linear guide rails 2, a spacing adjustment drive module 3, a second base body 4, a first traction module 5, a second traction module 6 and an infrared rangefinder 7. The two linear guide rails 2 are symmetrically installed on the upper part of the base 1, and the spacing adjustment drive module 3 consists of a first servo motor 31, a first base body 32, a screw rod 33, and a drive block 34. The first servo motor 31 is installed on the upper part of the base 1, the first base body 32 is slidably set on the upper part of the linear guide rail 2, the screw rod 33 is installed on the driving end of the first servo motor 31, and the drive block 34 is installed on the driving end of the first servo motor 31. 4 is installed at the bottom end of the first base body 32, the screw rod 33 is threadedly connected to the driving block 34, and the first traction module 5 is installed on the upper part of the first base body 32. Therefore, when the distance needs to be adjusted, the required adjustment distance is input on the control panel (not shown in the figure), and then the first servo motor 31 drives the screw rod 33 to rotate. Under the action of the threaded connection, the first base body 32 drives the first traction module 5 to move. During the movement process, the infrared rangefinder 7 is always in a monitoring state (the height of the detection end of the infrared rangefinder 7 is the same as the height of the first base body 32). When the distance reaches the set value, the infrared rangefinder 7 controls the first servo motor 31 to stop rotating immediately.

[0022] The second base body 4 is mounted on the linear guide rail 2. Under working conditions, the second base body 4 does not move. When maintenance is required, the bolts for mounting the second base body 4 are removed, and the second base body 4 can be moved. The second traction module 6 is mounted on the second base body 4.

[0023] The first traction module 5 and the second traction module 6 have the same structure, both including a second servo motor 51. The driving end of the second servo motor 51 is connected to a transmission shaft 52. A traction roller 53 is installed at the end of the transmission shaft 52 facing away from the second servo motor 51. The driving end of the second servo motor 51 and the transmission shaft 52 are fixedly connected via a coupling 54. The liquid crystal substrate glass 8 is located between the traction roller 53 of the first traction module 5 and the traction roller 53 of the second traction module 6. The driving direction of the first traction module 5 is clockwise, and the driving direction of the second traction module 6 is counterclockwise, so that the liquid crystal substrate glass 8 moves from top to bottom.

[0024] Therefore, when the wear amounts of the traction rollers 53 of the first traction module 5 and the traction rollers 53 of the second traction module 6 are inconsistent (i.e., eccentric wear occurs), the position of the traction rollers 53 of the first traction module 5 can be adjusted through the spacing adjustment drive module 3, so that the wear of the two traction rollers 53 can be made as consistent as possible. Compared with the existing method of manual adjustment, it not only has high accuracy, but also improves the efficiency, and can greatly extend the service life of the traction rollers.
