The specific embodiment
The utility model embodiment provides a kind of delivery roller, can realize in transmitting the process of glass substrate the thickness of the glass substrate that the gap energy Auto-matching between upper and lower delivery roller transmits.
As depicted in figs. 1 and 2, this delivery roller comprises axle drive shaft 1, also comprises:
The delivery roller that the utility model embodiment provides has structure as above, in transport process, when the thickness of transmitted glass substrate changes, the elastic construction generation elastic deformation arranging on delivery roller, the relative position of wheel body and outer wheel body in changing, thereby the gap between upper and lower delivery roller is changed, the gap of having realized between upper and lower delivery roller can automatically adjust along with the variation in thickness of transmitted glass substrate, avoided because of the glass fragment problem that thickness of matched glass substrate does not cause of the gap between upper bottom roller, greatly reduce the time that the gap between upper bottom roller is confirmed and adjusted.
Particularly, the material of interior wheel body 2 and outer wheel body 3 is the hard material that hardness is greater than glass substrate hardness, as materials such as corrosion-resistant steels.In glass substrate transport process, in order to make outer wheel body 3 there is less area of contact with glass substrate, thereby guarantee that the damage that delivery roller causes glass substrate in transport process is minimum, the outside face of outer wheel body 3 can be evagination peripheral curved, as shown in Figure 2.
In addition, in order to prevent in rotation process, interior wheel body 2 and outer wheel body 3 are along the axial direction generation relative displacement that is parallel to axle drive shaft 1, as shown in Figure 3 and Figure 4, this delivery roller can make the outside face of interior wheel body 2 along circumferentially having the first groove 6, meanwhile, make the inside face of outer wheel body 3 there is the first projection 7 coordinating with the first groove 6.In the process that interior wheel body 2 and outer wheel body 3 rotate simultaneously, the first groove 6 and the first projection 7 are nested, and guarantee that interior wheel body 2 and outer wheel body 3 be not along the axial direction generation relative displacement that is parallel to axle drive shaft 1.
Further, use above-mentioned delivery roller in transmitting the process of glass substrate, axle drive shaft 1 rotates, and drives the interior wheel body 2 being connected with axle drive shaft 1 to rotate, and interior wheel body drives outer wheel body 3 to rotate by link gear 4 again, thereby realizes the transmission to glass substrate.As shown in Figure 3, in the utility model embodiment, preferred linkage structure 4 comprises the second projection 41 on the outside face that is positioned at wheel body 2, and is positioned at the second groove 42 that the inside face of outer wheel body 3 matches with the second projection 41.In transmitting the process of glass substrate, interior wheel body 2 rotates under the drive of axle drive shaft 1, and then drive the second projection 41 being arranged on interior wheel body 2 outside faces to rotate, the second projection 41 touchings are positioned at the inwall of the second groove 42 on outer wheel body 3 inside faces, thereby drive outer wheel body 3 to rotate, realize the transmission to glass substrate.
In addition, in glass substrate transport process, when the thickness of transmitted glass substrate changes, there is elastic deformation in the elastic construction 5 on delivery roller, thereby change the gap between upper and lower delivery roller, therefore elastic construction 5 should have suitable elasticity modulus, and gap between upper and lower delivery roller can be automatically changed with the variation of thickness of glass substrate, also can be easy to reply simultaneously.As shown in figures 1 and 3, the utility model embodiment preferably includes at least three springs that make progress in week that are uniformly distributed in described interior wheel body 2 as elastic construction 5.For the ease of fixing of spring, this delivery roller can also make interior wheel body 2 have the 3rd groove 8 of fixing spring, makes outer wheel body 3 have the 4th groove 9 of fixing spring simultaneously.In addition, as shown in Figure 3, the 3rd groove 8 can be positioned on the first groove 5 arranging on wheel body 1.Similarly, the 4th groove 9 also can be positioned in the first projection 7 arranging on outer wheel body 3.
Further, in order to avoid better the delivery roller of hard to cause scratch to transmitted glass substrate, the delivery roller that the utility model embodiment provides can also comprise peripheral member 10.As depicted in figs. 1 and 2, peripheral member 10 is arranged on the outside face of outer wheel body 3.Peripheral member 10 is generally loop configuration, the material of peripheral member 10 is preferably the low material of hardness of the hardness ratio glass substrates such as rubber, plastics, thereby guarantee using delivery roller to transmit in the process of glass substrate, only have peripheral member 10 to contact with glass substrate, can not cause scratch to glass substrate.For the ease of fixing peripheral member 10, can also make the outside face of outer wheel body 3 match with peripheral member 10 along circumferentially thering are the 5th groove 11, the five grooves 11.
In addition, the utility model embodiment also provides a kind of substrate transfer structure, and as shown in Fig. 5, Fig. 6 and Fig. 7, this substrate transfer structure comprises at least one delivery roller as above.In glass substrate transport process, use upper and lower delivery roller to clamp glass substrate and transmit, the gap between upper and lower delivery roller can be set in advance as to the size that the thickness with the thinnest glass substrate matches, as shown in Figure 6.Exemplarily, as shown in Figure 7, when glass substrate 12 thickness that transmit surpass the gap between upper and lower delivery roller, the elastic construction 5 of delivery roller bottom that is positioned at glass substrate 12 tops is compressed, the elastic construction 5 that is positioned at delivery roller top is stretched, thereby make the gap between upper and lower delivery roller become large, with the consistency of thickness of glass substrate 12, thereby the gap of realizing between upper and lower delivery roller can automatically adjust along with the thickness of transmitted glass substrate 12.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
