Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid crystal glass substrate processing, and specifically relates to a paper-carrying trolley. Background Technique
[0002] Today, with the rapid development of liquid crystal display technology, as one of the core components, the production efficiency and quality control of liquid crystal glass substrates are crucial for the competitiveness of the entire industrial chain. In the production process of liquid crystal glass substrates, the semi-finished product packaging and wrapping link is a key step to ensure that the substrates are not damaged during transportation and storage. In this link, spacer materials such as spacer paper or PE film are widely used to effectively isolate the glass substrates from each other and prevent quality problems such as scratches and fractures caused by direct contact.
[0003] However, with the continuous progress of technology in the liquid crystal display industry and the rapid growth of market demand, the production rhythm of liquid crystal glass substrates has increased significantly, the number of substrates produced per unit time has increased substantially, and as a result, the consumption of spacer materials has increased sharply. The traditional method of handling spacer materials, that is, relying on manual collection, removal and separate storage of these spacer papers or PE films regularly, has gradually shown its limitations.
[0004] First of all, the manual collection method is inefficient and difficult to match the increasing production speed, which is likely to cause the accumulation of spacer materials at the production site, not only occupying valuable production space, but also possibly becoming a safety hazard, such as an increased risk of tripping and fire hazards. Secondly, manual operation is easily affected by human factors, and there is a possibility of misoperation or omission of collection, which affects the continuity and stability of the production line. Moreover, with the increase in labor costs, relying on manual collection and handling of spacer materials for a long time will significantly increase the operating costs of enterprises.
[0005] Therefore, there is an urgent need for an efficient, automated and safe spacer material collection and handling system to replace the traditional manual collection method, solve problems such as the accumulation of spacer materials, low processing efficiency and safety hazards in the production process of liquid crystal glass substrates, so as to further improve production efficiency, reduce operating costs and ensure the continuous and stable operation of the production line.

A number of reserved holes are provided at the edge of the middle layer frame body.
[0012] Furthermore, the paper bearing trolley further includes:
[0013] Support module, which includes a plurality of universal wheels and anchor bolts, and both the universal wheels and the anchor bolts are installed at the bottom end of the bottom layer frame body.
[0014] Furthermore, the paper pressing module includes a number of A-shaped frames fixed at the top end of the middle layer frame body. The number of A-shaped frames is evenly distributed in the horizontal direction, and a cross beam is commonly connected to the top ends of the number of A-shaped frames.
[0015] Furthermore, the paper pressing module includes swing arms symmetrically connected to the side of the paper bearing frame body. The swing arms can rotate relative to the paper bearing frame body. A hanging hole is reserved at the bottom end of each swing arm, and a pressing rod is commonly installed inside the two hanging holes on the same side of the paper bearing frame body.
[0016] Furthermore, limiting protrusions are integrally connected to both ends of the pressing rod, and the diameter of the limiting protrusions is larger than the inner diameter of the hanging holes.
[0017] The present utility model provides a paper bearing trolley. Compared with the prior art, it has the following beneficial effects:
[0018] For this paper bearing trolley, by evenly distributing the papers on the paper bearing frame body, when the papers on the paper bearing frame body are stacked to a certain number and the paper trolley needs to be replaced, to prevent the papers from slipping during the transfer process, the paper surface is pressed by the paper pressing modules on both sides, and the angle of the swing arms can be flexibly adjusted according to the thickness of the stacked papers. In this way, the purpose of collecting papers and facilitating regular cleaning of papers can be achieved. Compared with the existing manual method, the production efficiency is further improved, the operation cost is reduced, and the continuous and stable operation of the production line is guaranteed.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: A paper - supporting trolley is composed of a bottom - layer frame body 1, a paper - supporting frame body 2, two groups of paper - pressing modules 3, a middle - layer frame body 4, and several groups of support modules 5. Among them, the paper - supporting frame body 2 and the middle - layer frame body 4 are welded into a whole, and this whole is placed on the upper part of the bottom - layer frame body 1. Several layers of spacer paper 6 are stacked on the paper - supporting frame body 2. Two groups of paper - pressing modules 3 are symmetrically installed on the side of the paper - supporting frame body 2. The paper - pressing module 3 can press on the spacer paper 6 by its own gravity (as shown in the appendix Figure 4 ), to prevent the spacer paper 6 from slipping. The support module 5 includes a plurality of universal wheels 51 and anchor bolts 52. The universal wheels 51 and the anchor bolts 52 are both installed at the bottom end of the bottom - layer frame body 1. The whole paper - supporting trolley can move, and after moving to a designated position, it cannot move autonomously;
[0026] Specifically, the paper pressing module 3 includes a plurality of A-shaped frames 21 fixed to the top of the middle frame body 4, and the plurality of A-shaped frames 21 are evenly distributed in the horizontal direction, and the tops of the plurality of A-shaped frames 21 are commonly connected to a crossbeam 22, and a plurality of layers of spacer paper 6 are stacked on the crossbeam 22. Under the action of the deadweight, the two ends of the spacer paper 6 automatically droop to be spread on both sides of the A-shaped frame 21. The paper pressing module 3 includes a swing arm 31 symmetrically connected to the side of the paper supporting frame body 2. The swing arm 31 and the paper supporting frame body 2 can rotate relative to each other, and a hanging hole is reserved at the bottom end of each swing arm 31. 32. A pressure rod 33 is commonly installed inside the two hanging holes 32 on the same side of the paper supporting frame body 2. The two ends of the pressure rod 33 are integrally connected with a limiting protrusion 34. The diameter of the limiting protrusion 34 is larger than the inner diameter of the hanging hole 32. The limiting protrusion 34 can restrain the pressure rod 33 to prevent the pressure rod 33 from falling off from the hanging hole 32. A number of reserved holes 41 are set on the edge of the middle frame body 4. The reserved holes 41 can facilitate the insertion of the fork handle of a forklift, so that the whole (paper supporting frame body 2, middle frame body 4) stacked with the spacer paper 6 can be removed from the bottom frame body 1 by using a forklift.
[0027] The spacer paper 6 is evenly placed on the paper-supporting frame 2 by a paper-picking robot (not shown in the figure). When the spacer paper 6 is accumulated to a certain thickness, the staff manually rotates the swing arm 31 to swing outward, and then inserts the pressure rod 33 into the hanging hole 32. At this time, the staff releases the pressure rod 33 and under the action of gravity, it moves down to fit the spacer paper 6, thereby pressing the spacer paper 6 and preventing the paper from slipping. At this time, the operator drives a forklift to remove the paper-supporting frame 2 and the middle frame 4 filled with spacer paper from the bottom frame 1 through the reserved hole 41, and replaces them with the empty spare paper-supporting frame 2 and the middle frame 4, thereby achieving rapid recovery of production.
