The system of accurately automatically getting feeding spaced papers in the glass substrate production line
Technical field
The invention belongs to the processing equipment field in equipment manufacturing field, particularly precise electronic glass, be specifically related to accurately automatically get in a kind of glass substrate production line the feeding spaced papers system.
Background technology
The development of display industry has proposed more and more higher requirement to the maximization of glass substrate, and the design plan of uniqueness is arranged from processing, storage, the packing everyway of glass substrate.The maximization of glass substrate causes comfort feature that packing should consider to deposit, guarantees efficient and the safety of depositing again; Thereby taked vertically to lay the mode of glass substrate, efficient and the safety of storage transportation have so greatly been improved, but what need simultaneously to consider is to pollute and damage problem between the glass substrate that is in contact with one another, thereby has taked to add between glass substrate the method for feeding spaced papers.Under these circumstances, the problem that at first will consider how to get paper is loaded in rear processing, considers on the one hand the promptness of operation, adapts to the beat of glass substrate production line, safety, the accuracy that will consider to get on the other hand paper.
In the prior art, glass substrate after treatment is placed on the A type frame and is transported to next station.When glass substrate carries out next process, need to take off glass substrate from A type frame, so just require before getting glass substrate, first feeding spaced papers to be taken off.
Notification number is that the Chinese patent of CN201154479Y discloses in a kind of glass substrate production line automatically paper extraction unit, and it comprises general frame, be assemblied in slip on the general frame gets the paper assembly, is located at ground and is positioned at slide the A type frame of getting paper assembly integral body below and power system and the electric control system of supporting setting.General frame in this patent adopts the technology of welding fabrication, because welding technique is subjected to a plurality of factor affecting, welding precision is wayward, can't repair and adjust along with natrual ageing, the generation deformation of guide rails assembling fine strain of millet, and the amount of deflection that can not active accommodation naturally droops of the guide supporting beam after the welding.Get the paper assembly and adopt the vacuum cup structure, tend to get the paper failure because vacuum failure causes, and greatly increased the improper off-time of manufacturing line, directly affect production capacity and the economic benefit of manufacturing line, its major cause is: the time, too short sucker was not inhaled, and will use the long period and want each sucker to suct feeding spaced papers; Next is that reliability is lower, and sucker also may make the feeding spaced papers landing after sucting feeding spaced papers at last for various reasons, causes and gets the paper failure.Described slip is got the paper assembly and is adopted 2 axles to get the paper technology, and when the feeding spaced papers on getting paper parts and A type frame was not parallel, error was difficult for adjusting, and has increased and has got the paper failure rate; The cost of getting the industrial robot that paper uses is also higher, and disposable infusion of financial resources is larger, and the restriction that opened up by the robots arm, causes the paper work of getting of larger glass interval paper that very large difficulty is arranged.
