Description
Technical Field
The utility model relates to a glass substrate processing technology field, concretely relates to draw gear.
Background
Liquid Crystal Displays (LCDs) are used in digital watches and one type of display for many portable computers. The LCD display uses two sheets of polarized material with a liquid crystal solution between them. When current is passed through the liquid, the crystals will rearrange so that light cannot pass through them. Thus, each crystal acts like a louver, both allowing light to pass through and blocking light. Liquid Crystal Display (LCD) technology information products are now developed toward the goals of being light, thin, short, and small, and it is certainly no exception to display products having a long history in the computer periphery. Under the precondition of easy carrying and transportation, the conventional display methods such as CRT video display and LED display are all limited by the factors of too large volume or huge power consumption, which cannot meet the practical requirements of users. The development of the liquid crystal display technology is just in line with the trend of the current information products, and the user can enjoy the best visual environment no matter the advantages of right-angle display, low power consumption, small volume, zero radiation and the like.
In the production process of the liquid crystal glass substrate, a split type traction roller is adopted to form clamping and guiding effects on two sides of the glass substrate, but the horizontal degree of the two traction rollers for clamping the glass substrate cannot be adjusted by the existing split type traction roller, and the horizontal degree of the clamping surface of the traction roller at the far end and the near end further influences the clamping and guiding effects of the traction roller on the glass substrate. The existing clamping mechanism clamps the glass substrate through the connecting rod and the counterweight mechanism, when the clamping force is too large, the quality of the substrate is influenced, and when the clamping force is too small, the glass substrate is easy to be clamped. In chinese utility model patent application No. cn201610934166.x, a device for adjusting the shape of a glass substrate is disclosed, which comprises a shifting fork device arranged in the lower part of a drawing roller for forming the glass substrate by pulling, i.e. in the annealing furnace, wherein the shifting fork device can be adjusted to be in angle contact with the glass substrate surface, so as to apply an acting force opposite to the existing shape to the glass substrate, thereby stabilizing or optimizing the BOW type of the glass substrate. In practical production, when the glass substrate overflows the down-flow plate, the annealed BOW is very sensitive to mechanical force, requires higher precision, and can be applied to a traction guide device of a high-temperature annealing furnace to maintain or improve the annealed BOW of the glass substrate. The split type traction roller in the prior art has the defects that the levelness of the far end and the near end cannot be corrected, and the clamping force is easy to be too large or too small.

As shown in fig. 5, when the traction apparatus of the present invention is used in the glass substrate production process, a traction apparatus a and a traction apparatus B are respectively disposed on two sides of a glass substrate 9, the tilting mechanism 3 is used to adjust the tilt of the first bearing box 11 and the second bearing box 14, the limiting mechanism 4 is used to limit the first bearing box 11 to move towards the second bearing box 14, the buffer mechanism 5 is used to limit the second bearing box 14 to move towards the first bearing box 11 and buffer the impact of the pulling roll head 13 of the second bearing box 14 on the glass substrate 9, so that the clamping force between the traction apparatus a and the traction apparatus B on the glass substrate 9 is a flexible clamping force, the folding mechanism 7 can adjust the relative height between the traction apparatus a at two ends of the glass substrate 9 and the pulling roll head 13 of the traction apparatus B, the pulling roll heads 13 at both ends are aligned to the horizontal plane. As shown in fig. 5, the correction method may be to adjust the levelness of the pull roll heads 13 at both ends using the laser beam 81 of the laser level 8 as a horizontal reference line. This is accomplished by placing a stand (not shown) behind the proximal pull roll head 13, which can be adjusted in level, and placing the laser level 8 on top of the stand. The laser level meter 8 irradiates horizontal laser beams 81 on the upper surface of the drawing roller head 13 at the near end in parallel and irradiates towards the far end, when the parallel laser beams 81 appear on the upper surface of the drawing roller head 13 at the far end, namely two drawing roller heads 13 are horizontal, if the parallel laser beams do not appear, the height position of the drawing roller head 13 and the inclination angle of the drawing roller head 13 are changed by adjusting the folding mechanism 7, so that the drawing roller heads 13 at the far end and the near end are horizontal. The roller head 13 of the far-end and near-end traction roller keeps better levelness and has better effect on the annealing process of the glass substrate 9. The measuring method fills the blank that the levelness of the roller head 13 of the far-end and near-end traction roller cannot be corrected in the prior art.
