Abstract
The invention belongs to the field of machinery and in particular relates to a free roller wheel, which can protect a glass face or a substrate face in liquid crystal glass or a liquid crystal substrate conveying process. The free roller wheel comprises a ring roller, a tension sleeve and a rotating shaft, wherein the ring roller is arranged on the rotating shaft through the tension sleeve. The free roller wheel is structurally characterized mainly in that: the fit tolerance between the tension sleeve and the rotating shaft is interference fit and the fit tolerance between the tension sleeve and the ring roller is clearance fit. When the rotating shaft stops to rotate, the glass or the substrate moves continuously because of inertia, and the free roller wheel also rotates with the glass or the substrate, so that relative slip is not caused; even though the glass or the substrate bumps a stop dog, the speed of the glass or the substrate is slowly reduced until the roller wheel stops to rotate, so that the glass face or the substrate face can be prevented from being scrapped, the problem that a scratch or a roller wheel mark is generated on the glass or the substrate because the stop position cannot be accurately controlled is solved, and the production efficiency is not affected. Therefore, the free roller wheel has a wide market prospect.
Description
Technical field
The invention belongs to mechanical field, but relate in particular to a kind of in liquid-crystalline glasses or crystal liquid substrate transmission course the free roller of cover glass face or real estate.
Background technology
We know that in the production technology of liquid-crystalline glasses or crystal liquid substrate, glass or substrate are transferred forward under the rotation of roller.Glass on the manufacturing line or substrate need stop in some position in the handover process, if stop position control is bad, will cause the relative friction of glass or substrate and roller, thereby on glass or substrate, stay cut, influence the quality of liquid-crystalline glasses or crystal liquid substrate.Liquid-crystalline glasses or crystal liquid substrate mainly contain three kinds of situations in the handover process need stop: 1. when glass or substrate are through detection zone, need temporarily stop so that product is detected, continue after detection finishes to move again.2. after glass or substrate are transferred certain distance, need move being on 90 ° the direction with original transfer direction, this also needs glass or substrate to transfer operation temporarily to stop.3. glass or substrate bevelled situation may occur in the process of glass or the substrate handover in different handover operations, this just needs to transfer operation and temporarily stops, and transfers after glass or substrate are adjusted and ajusted again.Up to the present, when liquid-crystalline glasses or crystal liquid substrate need stop to transfer, normal conditions bottom roller and transmission axle can stop together.When roller stops, can producing hard friction rather than friction of rolling between glass or substrate and the roller, cause glass face or real estate to mark cut.In order to address this problem, most of enterprise adopts stepping motor usually.Motor slowly slows down after receiving danger signal, to reduce the friction of glass and roller.But the stop position of adjusting glass or substrate by the standing time that delays motor is very difficult, and this method of adjustment can reduce the production efficiency of glass or substrate, so and because cut or roller seal also may appear in the position that can't accuracy control stops on glass or substrate.Though the material of the roller that uses on glass or the substrate transfer line adopts hardness compare low UHMW-PE, the UPE of glass mostly, accidentally also can on the glass of high price or substrate, mark cut, produce bad product.
Summary of the invention
The technical matters that the present invention solves is, solves above-mentioned the deficiencies in the prior art, but provide a kind of when transmission course stops the free roller of cover glass face or real estate.
Technical scheme of the present invention is that a kind of free roller comprises annular roller, tensioner cover and S. A., the annular roller is set on the S. A. by tensioner, the keystone configuration characteristics are, the tensioner cover is an interference fit with the tolerance on fit of S. A., and the tensioner cover is a free-running fit with the tolerance on fit of roller.
Among the present invention, interporal lacuna is the 0.1-0.5 millimeter in roller and the tensioner cover, and roller and tensioner cover monolateral gap, side are the 0.1-0.4 millimeter.
The invention has the beneficial effects as follows, because the tensioner cover is an interference fit with the tolerance on fit of S. A., the tensioner cover is a free-running fit with the tolerance on fit of roller, when S. A. stops operating, glass or substrate will continue to move owing to inertia, and free roller also can and then rotate, thereby can not produce slide relative, even if glass or substrate are run into hill holder and also can slowly be slowed down and no longer rotate up to roller, so can prevent the scuffing of glass face or real estate, solved because of the difficult problem of cut or roller seal can't the accuracy control stop position on glass or substrate, occurring, and can not influence production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention, also is the scheme drawing of a kind of embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B place enlarged drawing among Fig. 2.
The specific embodiment
The present invention is further detailed explanation below in conjunction with drawings and the specific embodiments.
As Fig. 1, Fig. 2, free roller shown in Figure 3, comprise annular roller 1, tensioner cover 2 and S. A. 3, the annular roller is set on the S. A. by tensioner, tensioner cover 2 is an interference fit with the tolerance on fit of S. A. 3, guarantee that S. A. cooperates closely with the tensioner cover, tensioner cover 2 is a free-running fit with the tolerance on fit of roller 1, roller 1 is the 0.1-0.5 millimeter with tensioner cover 2 interior interporal lacunas, it is the 0.1-0.4 millimeter that roller 1 overlaps monolateral gap, 2 sides with tensioner, in the present embodiment in conjunction with Fig. 3, it is 0.4 millimeter that roller 1 overlaps 2 endoporus clearance C with tensioner, and it is 0.3 millimeter that roller 1 overlaps the monolateral clearance D in 2 sides with tensioner.
The principle of work of the free roller of the present invention is: when S. A. stops operating, glass or substrate will continue to move owing to inertia, and free roller also can and then rotate, thereby can not produce slide relative between glass or substrate and the free roller, even if glass or substrate are run into hill holder and also can slowly be slowed down and no longer rotate up to free roller, so can prevent the scuffing of glass face or real estate, solved because of the difficult problem of cut or roller seal can't the accuracy control stop position on glass or substrate, occurring, and can not influence production efficiency, have vast market prospect.
