As the subsection control device is provided with the pressure controller, the oil mist separator and the program controller, the knife flywheel can be controlled, and the subsection control for the knife flywheel pressure of the transverse cutting machine can be carried out according to technological requirements, so that plate breaking or cracking caused in a breaking process is reduced, the continuity of production is improved, the needs of normal production are met, a hot end process cannot be affected, the matching problem of marking depth and non-flow direction thickness difference of glass plates is overcome, and the ratio of the marking depth to the thickness of substrate glass at different positions is ensured to keep relatively unchanged.
Description
Technical field
The utility model belongs to TFT base plate glass production field, relates to a kind of control device of transverse cutting unit break bar, is specifically related to the device that a kind of line of the break bar to transverse cutting unit pressure carries out segmentation control.
Background technology
Usually, as being shaped continuously from melten glass, the method for the sheet glass that the making of the flat-panel screens that the liquid-crystal display of take is representative etc. is used, be well known that glass tube down-drawing and upper daraf(reciprocal of farad), in addition, glass tube down-drawing can also roughly be divided into overflow downdraw and slot draw method.
For the indicating meter of semiconductor power, must there is very high surface quality in particular for the glass of the TFT/LCD indicating meter of graphoscope, to allow the material of application semiconductor type.The glass that this surface quality is higher obtains by overflow downdraw.Overflow downdraw (fusion downdraw method) is a kind of method of sheet glass of producing in the glass preparation technology.With other technique, compare, for example, float glass process and slit tractive technique, overflow downdraw is produced the sheet glass with excellent planeness and slickness surface, and does not need to use post forming technique (grinding, polishing etc.).
Overflow downdraw is a kind of main mode of production of TFT planar substrates glass, overflow downdraw can be produced the good sheet glass of surface quality, and wherein the Main Function of transverse cutting unit is: the planar substrates glass that the next method of overflow is produced by size rule break disconnected.Line pressure to break bar in scratching process has strict processing requirement, too high or too low all can the breaking after line in disconnected process of the line pressure of break bar caused slashings or split plate, greatly reduce the continuity of production, also can cause serious impact to hot junction technique and production simultaneously.
In transverse cutting unit break bar scratching process, because sheet glass flows to uneven thickness on direction non-, relatively thick near glass plate edge place sheet glass, middle part is consistent relatively.The pressure of break bar in scratching process is realized by relief valve, the relief valve output pressure can not be adjusted according to break bar difference of present position on sheet glass in the break bar scratching process, at scratching process break bar line pressure, remain unchanged, basic identical in the non-depth of score that flows on thickness of sheet glass.In the disconnected process of breaking of base plate glass, the relatively thick position of base plate glass is as base plate glass edge, easily causes effectively to break disconnectedly, the uneven phenomenon in limit occurs breaking.
The utility model content
The purpose of this utility model is to overcome the problems of the prior art, the device that provides a kind of line of the break bar to transverse cutting unit pressure to carry out segmentation control, it can realize the pressure of transverse cutting unit break bar in scratching process, and with break bar, the difference of the position on sheet glass changes, the pressure requirement during with assurance cutting different positions.
For achieving the above object, the utility model adopts following technical scheme:
The utility model comprises the pressure controller be connected with break bar, and described pressure controller is connected with respectively oil mist separator and sequence controller.
Described oil mist separator is connected by pipeline with pressure controller.
Described sequence controller and pressure controller are connected by cable that can transmission of electric signals.
With respect to prior art, the beneficial effect the utlity model has: the utility model is due to pressure controller being set, oil mist separator and sequence controller, so can control break bar, according to processing requirement, transverse cutting unit break bar pressure is carried out to segmentation control, reduced in breaking disconnected process and caused slashings or split plate, improved the continuity of producing, meet the normal needs of producing, and can not impact hot junction technique, overcome the non-matching problem that flows to difference in thickness of depth of score and sheet glass, guarantee than relative, to remain unchanged with substrate glass thickness in different positions place depth of score.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is pressure controller, and 2 is oil mist separator, and 3 is sequence controller, and 4 is break bar, and 5 is base plate glass.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the utility model comprises the pressure controller 1 be connected with the break bar 4 of transverse cutting unit, and pressure controller 1 is connected with oil mist separator 2 by pipeline, and pressure controller 1 is by cable linker controller 3 that can transmission of electric signals.Described transverse cutting unit comprises for the piping system on transverse cutting unit, all cylinder actions are controlled with for the transverse cutting unit everything is carried out to programme controlled Controlling System.Pressure controller 1 and oil mist separator 2 are arranged in the transverse cutting unit piping system.Sequence controller 3 is arranged in the transverse cutting unit Controlling System.
Wherein, the Main Function of pressure controller 1 is to control the line pressure of transverse cutting unit break bar 4 by adjusting output pressure; The Main Function of oil mist separator 2 is that the gas to input pressure controller 1 carries out the mist of oil separation, removed in input gas containing oil molecule, improved the cleanliness factor of gas; Sequence controller 3 Main Functions are to work out different sequence of control according to different line pressure curves the electrical signal of input pressure controller 1 is carried out to time variable control, the output pressure of pressure controller 1 is changed by the line pressure curve, realize the segmentation of the required pressure of break bar 4 line is controlled.
In transverse cutting unit break bar scratching process, because base plate glass flows to uneven thickness on direction non-, relatively thick near base plate glass 5 edges, middle part is consistent relatively.According to above characteristics, need to carry out step-by-step design to the break bar pressure curve of ruling, near the relatively thick position of base plate glass 5 edges, pressure is larger, and middle part pressure is basically identical.Make the break bar depth of score constant with the ratio of the thickness of glass substrate, like this in the disconnected process of breaking of base plate glass 5, can be at the relatively thick position of base plate glass 5 as base plate glass 5 edges, cause and can't effectively break disconnectedly, break the uneven phenomenon in limit.
The utility model has overcome depth of score and the non-matching problem that flows to difference in thickness of sheet glass, guarantee than relative, to remain unchanged with substrate glass thickness in different positions place depth of score, improve the line of glass substrate and break disconnected quality, improved the continuity of producing, meet the normal needs of producing, and can not impact hot junction technique.
