Description

Technical Field

[0001] The invention relates to the technical field of liquid crystal glass, and in particular to a multi-layer short roller amplitude adjustment device. Background Art

[0002] In the production process of liquid crystal glass substrates, after the glass plate is formed, it is necessary to clamp the two sides of the glass plate with multiple layers of short rollers. According to the process requirements, they are divided into 2# rollers, 4# rollers, 6# rollers, 8# rollers, etc. to ensure the thickness of the glass plate. During the rotation of the short rollers, the clamping force between the rollers and the glass plate is required to be consistent and there is no misalignment or virtual clamping, so as to ensure the stability of the width and thickness of the glass plate during the pull-down process, thereby reducing the occurrence of defects and ensuring the normal progress of production.

[0003] Since the liquid crystal glass substrate uses a multi-roll clamping method during the annealing and pulling process to provide stable clamping for the glass pulling, the adjustment of the short roller top wire length plays a very important role in the running position of the traction roller in the annealing furnace. At present, the adjustment amount of the roller top wire length is detected by manual measurement. Due to the difference in the placement of the ruler and subjective factors during manual measurement, the accuracy of the measurement cannot be guaranteed, which will have an adverse effect on the accurate determination of the roller adjustment range.

[0040] Embodiment 3

[0041] like Figure 1-Figure 8 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0042] In order to allow the glass to accurately enter between the two sets of auxiliary measuring components when being transported, this embodiment provides the following technical solutions:

[0043] The straightening assembly 8 comprises a vertical rod 81, one end of the top surface of the workbench 7 is fixedly connected to the vertical rod 81, one side of the vertical rod 81 is fixedly connected to a sliding sleeve 82, a sliding rod 83 is slidably connected inside the sliding sleeve 82, one end of the sliding rod 83 is rotatably connected to a rotating rod 84, both ends of the rotating rod 84 are fixedly connected to straightening wheels 85, one side of the sliding rod 83 is fixedly connected to a reset damping rod 86, one end of the reset damping rod 86 is fixedly connected to one side of the sliding sleeve 82.

[0044] The conveying motor 32 in the conveying assembly 3 drives the conveying rod 33 to rotate. When the conveying rod 33 rotates, the conveying shaft 34 is driven to rotate, thereby driving the I-shaped wheel 35 to rotate, thereby realizing the conveying of the glass;

[0045] Through the cooperation between the two groups of straightening wheels 85 and the reset damping rod 86 in the straightening assembly 8, it is possible to clamp and limit the glass of different thicknesses to ensure that the glass can accurately enter between the two groups of rubber wheels 985, which is convenient for subsequent inspection.

[0046] The working principle and use process of the present invention:

[0047] In use:

[0048] When in use, first, the distance between the two sets of auxiliary measuring components 98 is adjusted according to the thickness of the glass to be detected. When adjusting, the dial 934 is rotated. When the dial 934 is rotated, the sleeve 935 and the adjusting threaded rod 932 are driven to rotate. When the adjusting threaded rod 932 is rotated, the abutment block 933 is driven to move. When the abutment block 933 moves, the auxiliary measuring component 98 is driven to move. When the auxiliary measuring component 98 moves to a suitable position, the rotation of the adjusting threaded rod 932 is stopped. At this time, the staff can calculate the moving distance of the auxiliary measuring component 98. , when calculating, first, look at the thread scale 937 on the surface of the scale cylinder 936, and look at the data on the thread scale 937 to get the number of rotations of the adjustment threaded rod 932. The amplitude of the adjustment screw when the adjustment threaded rod 932 rotates one circle is a fixed value - 1.5mm, so the adjustment amplitude corresponding to one side of the regular hexagon is 0.25mm. At this time, the staff is looking at the scale on the hexagonal block 9342. Assuming that the scale before rotation is 1, and the scale after rotation is 5, the number of circles is 3, and the distance of advancement can be calculated as L = 1.5*3+0.25(5-1), and the data can be calculated as 5.5;

[0049] When the annealed glass falls on the I-shaped wheel 35, the conveying motor 32 is started. When the conveying motor 32 works, the conveying rod 33 is driven to rotate. When the conveying rod 33 rotates, the I-shaped wheel 35 is driven to rotate. When the I-shaped wheel 35 rotates, the glass can be conveyed. When the substrate glass is conveyed between the two groups of straightening components 8, the substrate glass will squeeze the straightening wheel 85. When the straightening wheel 85 is squeezed, the rotating rod 84 and the sliding rod 83 are squeezed. When the sliding rod 83 rotates, the reset damping rod 86 is squeezed. When the substrate glass passes between the two groups of straightening wheels 85 as the substrate glass moves, it can be ensured that the glass is located in the middle of the I-shaped wheel 35, so that the substrate glass can smoothly enter between the two groups of rubber wheels 985. At this time, the driving motor 982 is started. When the driving motor 982 works, the transmission rod 983 is driven to rotate. When the transmission rod 983 rotates, the connecting rod 984 is driven to rotate, so that the glass can be conveyed and the glass can be detected.
