[0035] Please refer to Figures 1, 2 and 3, which are schematic diagrams of structures of different angles of a grinding device 10 for glass strips 20 in some embodiments. The grinding device 10 provided in the present application can be used in the production process of optical glass, for example, to grind a plate-shaped or strip-shaped glass strip 20 to eliminate unevenness, stripes, cracks, etc. on the surface of the glass strip 20, or to form a required arc chamfer at the chamfer position of the glass strip 20.

[0036] In some embodiments, the grinding device 10 for glass strip 20 includes a workbench 11, a positioning mechanism 12 and a grinding mechanism 13. The workbench 11 is used to place the glass strip 20 to be ground. The positioning mechanism 12 includes a support assembly and a pressing element 121. The support assembly is arranged on the workbench 11, and the pressing element 121 is arranged on the support assembly. The support assembly is used to provide structural support for the pressing element 121, so that the pressing element 121 can be located on the side of the glass strip 20 facing away from the workbench 11. The pressing element 121 can move in a direction close to or away from the workbench 11 relative to the support assembly. When the pressing element 121 moves in a direction close to the workbench 11 to abut against the glass strip 20, the glass strip 20 can be pressed on the surface of the glass strip 20 facing away from the workbench 11 to prevent the glass strip 20 from shifting during the grinding process. When the grinding is completed, the pressing element 121 can be moved in a direction away from the workbench 11 to release the glass strip 20, so as to remove the ground glass strip 20.

[0037] As shown in combination with FIG. 4 and FIG. 5 , in some embodiments, the grinding mechanism 13 includes a spindle housing 131, a transmission spindle 132, a driving element (not shown) and a grinding wheel 133. The spindle housing 131 is arranged on the peripheral side of the workbench 11, and the transmission spindle 132 passes through the spindle housing 131 and rotates with the spindle housing 131. The spindle housing 131 serves as a carrier of the transmission spindle 132. The grinding wheel 133 is arranged at the end of the transmission spindle 132 close to the workbench 11 by any applicable connection method such as a fastening nut, and the end of the transmission spindle 132 away from the grinding wheel 133 is used to dock with the output shaft of the driving element, and the driving element includes but is not limited to a motor. During the grinding operation, the output shaft of the driving element rotates, which can drive the transmission spindle 132 to drive the grinding wheel 133 to rotate, thereby grinding the glass strip 20. For example, the grinding wheel 133 grinds the end face or side face of the glass strip 20 on the circumferential side of the workbench 11 to eliminate local unevenness, stripes, cracks or other defects on the end face or side face of the glass strip 20. The grinding wheel 133 can also grind the chamfer of the glass strip 20 to eliminate local defects at the chamfer position, or grind the chamfer position into a desired arc.

[0038] As shown in combination with FIG. 2 and FIG. 6 , in some embodiments, the grinding mechanism 13 may be provided with a flat grinding wheel and a curved grinding wheel adapted to the transmission main shaft 132. When the side or end face of the glass strip 20 needs to be ground, a flat grinding wheel may be provided at the end of the transmission main shaft 132. When the chamfered position of the glass strip 20 needs to be ground to obtain the required curved chamfer, the grinding wheel 133 at the end of the transmission main shaft 132 may be replaced with a curved grinding wheel. The curved shape of the curved grinding wheel may be adapted to the chamfer arc required for the glass strip 20, so that the chamfer of the glass strip 20 may be directly ground. FIG. 6 illustrates a curved grinding wheel adapted to the chamfer arc of the glass strip 20. In some embodiments, the material of the grinding wheel 133 may be diamond, and the particle size of the grinding wheel 133 may be 80 meshes to 120 meshes, which may be specifically designed according to the grinding requirements. Of course, the grinding position of the glass strip 20 and the shape and specifications of the grinding wheel 133 are not limited to the above records, and can be set according to specific needs. The grinding mechanism 13 can also be provided with a plurality of plane grinding wheels or curved grinding wheels with different shapes and specifications, which can be replaced according to glass strips 20 of different specifications to meet the grinding processing of glass strips 20 of different specifications.

[0039] In the above-mentioned grinding device 10 for glass strip 20, the grinding mechanism 13 can grind the glass strip 20 on the peripheral side of the workbench 11 through the grinding wheel 133, for example, grinding the surface defects such as protrusions, stripes, cracks, etc. of the glass strip 20. When it is necessary to grind the chamfer of the glass strip 20 to form an arc chamfer, the arc surface grinding wheel 133 can also be used to grind the chamfer. Therefore, the grinding device 10 can directly grind the local area of ​​the end face and side face of the glass strip 20, or directly grind the chamfer. Compared with the whole surface cutting processing method, it can effectively reduce the wear of the material, for example, it can reduce the material loss of the grinding process by about 20%, thereby reducing the influence of the processing process on the size specifications of the glass strip 20, and improving the grinding quality and the profit margin of the glass strip 20. In addition, directly grinding the surface locally, or using a curved grinding wheel with a suitable shape to directly grind the chamfer, can also reduce defects such as scratches, broken edges or corners of the glass strip 20 during the grinding process, thereby improving the processing yield of the glass strip 20.

[0040] In some embodiments, the grinding mechanism 13 may also be provided with an automated machine for driving the grinding mechanism 13 to move, for example, driving the driving element, the transmission spindle 132, the spindle housing 131 and the grinding wheel 133 to move as a whole relative to the workbench 11, thereby driving the grinding wheel 133 to move in a direction parallel or perpendicular to the side of the glass strip 20, so as to grind different positions of the glass strip 20. During the grinding process, the parameters of the automated machine and the driving element may be set according to the size specifications of the glass strip 20, so as to adjust the rotation speed, feed rate and other parameters of the grinding wheel 133, so as to achieve precise grinding of the glass strip 20.

[0041] Referring to FIG. 1 and FIG. 3 , in some embodiments, the support assembly includes an adjustment plate 122 and two vertical plates 123. The two vertical plates 123 are disposed on the positioning mechanism 12 and are disposed opposite to each other. The two ends of the adjustment plate 122 are respectively connected to the two vertical plates 123. During the grinding operation, the glass strip 20 can be disposed between the two vertical plates 123, and the adjustment plate 122 is opposite to the glass strip 20. The pressing element 121 passes through the adjustment plate 122 and can move relative to the adjustment plate 122 in a direction perpendicular to the adjustment plate 122.

[0042] In some embodiments, the pressing element 121 includes a screw portion 1211, an adjusting portion 1212 and a pressing head 1213. The screw portion 1211 is provided with the adjusting portion 1212 and is threadedly matched with the adjusting plate 122. The screw portion 1211 may be substantially perpendicular to the adjusting plate 122. The adjusting portion 1212 is connected to an end of the screw portion 1211 away from the workbench 11, that is, it is arranged on the side of the screw portion 1211 located on the adjusting plate 122 facing away from the workbench 11, and the pressing head 1213 is connected to an end of the screw portion 1211 close to the workbench 11. The adjusting portion 1212 may be arranged in a petal shape or any other shape, so as to facilitate manual rotation of the adjusting portion 1212, thereby driving the screw portion 1211 to rotate relative to the adjusting plate 122. Since the screw part 1211 is threadedly matched with the adjustment plate 122, when the screw part 1211 rotates relative to the adjustment plate 122, it can move relative to the adjustment plate 122 in a manner perpendicular to the adjustment plate 122, thereby driving the pressure head 1213 to approach the glass strip 20 until the glass strip 20 is pressed against the workbench 11, thereby preventing the glass strip 20 from swinging during the grinding process and affecting the grinding accuracy. It can be understood that by manually rotating the adjustment part 1212, the distance between the pressure head 1213 and the workbench 11 can be flexibly adjusted to achieve the pressing of glass strips 20 of different thickness specifications, so that when replacing glass strips 20 of different thickness specifications, there is no need to adjust the positioning mechanism 12, which can improve the applicable scope of the positioning mechanism 12.

[0043] In some embodiments, the positioning mechanism 12 may include a plurality of pressing elements 121, for example, three pressing elements 121, and the plurality of pressing elements 121 are sequentially arranged at intervals in the direction of the connection line of the two vertical plates 123, so as to press the glass strip 20 from multiple positions and improve the positioning effect of the glass strip 20. Referring to FIG8, in some embodiments, the pressing element 121 also includes a protective structure 1214, which is arranged on the pressing head 1213 and at least covers the surface of the pressing head 1213 facing the workbench 11, and the material hardness of the protective structure 1214 is less than the material hardness of the pressing head 1213. The protective structure 1214 can be attached to the surface of the pressing head 1213 facing the workbench 11, or can be covered on the entire pressing head 1213. The protective structure 1214 with a smaller hardness is arranged to contact the glass strip 20, so as to prevent the pressing element 121 from scratching the glass strip 20 when pressing the glass strip 20, which is conducive to improving the product yield. The material of the pressing head 1213 includes but is not limited to any suitable metal material. The pressing head 1213 can be integrally formed with the screw portion 1211 to enhance the structural strength of the pressing element 121. The material of the protective structure 1214 includes but is not limited to any suitable non-metallic material such as rubber or polyurethane that can provide protection for the glass strip 20.

[0044] As shown in FIG. 2 , FIG. 6 and FIG. 7 , in some embodiments, the positioning mechanism 12 further includes a positioning plate 124, which is connected to the two vertical plates 123 and is located outside the workbench 11. The extending direction of the positioning plate 124 may be substantially perpendicular to the table surface of the workbench 11, and the positioning plate 124 is used to abut at least part of the side surface of the glass strip 20. The positioning plate 124 may be spaced apart from the workbench 11. When the glass strip 20 is disposed on the workbench 11, the side surface of the glass strip 20 abuts against the positioning plate 124, so that the positioning plate 124 can be accurately positioned. The portion of the glass strip 20 between the positioning plate 124 and the workbench 11 is suspended, so that the position of the glass strip 20 to be ground is exposed between the positioning plate 124 and the workbench 11, so that the grinding wheel 133 can grind the glass strip 20 on the peripheral side of the workbench 11 and below the positioning plate 124. During the production process, the spacing between the positioning plate 124 and the workbench 11, as well as the distance between the positioning plate 124 and the table top of the workbench 11 can be designed according to the size specifications of the glass strip 20, so that the positioning plate 124 can both abut against the side of the glass strip 20 and not completely block the side of the glass strip 20, thereby allowing the portion of the glass strip 20 to be ground or the chamfer to be placed in a position not blocked by the positioning plate 124 and the workbench 11, so as to facilitate the grinding wheel 133 to grind the glass strip 20.

[0045] As shown in combination with FIG. 1 and FIG. 8 , in some embodiments, the workbench 11 includes a substrate 111, a table 112, and four connecting members 113. The substrate 111 and the table 112 are arranged opposite to each other and are substantially parallel to each other. The four connecting members 113 are connected to the substrate 111 and the table 112 by any applicable connection method such as welding, screw connection, etc., and are located at the four corners of the substrate 111. In some embodiments, the sizes of the four connecting members 113 can be controlled, for example, the lengths of the four connecting members 113 are made substantially equal, so as to control the substrate 111 and the table 112 to be substantially parallel. The four connecting members 113 can also improve the connection stability between the substrate 111 and the table 112, thereby improving the structural strength of the workbench 11. During the grinding operation, the substrate 111 can be placed on a flat ground so that the surface of the table 112 facing away from the substrate 111 is substantially horizontal to improve the grinding accuracy. The surface of the table 112 facing away from the substrate 111 is the table surface for placing the glass strip 20.

[0046] In some embodiments, the workbench 11 further includes a protective layer 114, which is disposed on the surface of the table 112 facing away from the substrate 111 and at least covers the area of ​​the table 112 for placing the glass strip 20. The protective layer 114 may also cover the entire surface of the table 112, and the hardness of the material of the protective layer 114 is less than the hardness of the table 112. The protective layer 114 with a smaller material hardness is provided for placing the glass strip 20, which can provide protection for the glass strip 20, prevent the glass strip 20 from being scratched by the table 112, and improve the product yield. The material of the protective layer 114 includes but is not limited to any suitable non-metallic material such as rubber or polyurethane materials that can provide protection for the glass strip 20, and other components of the workbench 11 can be made of any suitable metal material to improve the structural strength of the workbench 11.

[0047] Referring to FIG. 1 and FIG. 2 , in some embodiments, the grinding device 10 may further include a cooling mechanism (not shown), which may include a liquid circulation pipeline, a spray pipeline, and a nozzle, the nozzle being connected to the spray pipeline and used to spray a cooling liquid toward the grinding position of the grinding wheel 133, for example, spraying a cooling liquid toward the contact position between the grinding wheel 133 and the glass strip 20, so as to cool the glass strip 20 during the grinding process, and prevent the glass strip 20 from being overheated and cracked. The cooling liquid sprayed between the grinding wheel 133 and the glass strip 20 can be recovered into the circulation pipeline through the pipeline, and after cooling, it flows back to the spray pipeline and is sprayed out from the nozzle, so as to realize the recycling of the cooling liquid. In some embodiments, part of the spray pipe can be connected to the spindle housing 131, and the spray head is aligned with the position of the grinding wheel 133 toward the positioning plate 124, so as to accurately spray the coolant on the grinding position of the grinding wheel 133. At the same time, the spray head and the spray pipe can also move with the movement of the spindle housing 131, so that the spray head is always aligned with the grinding wheel 133, and there is no need to adjust the position of the spray head during the movement of the grinding wheel 133 relative to the workbench 11, thereby improving the convenience of use. Of course, according to different specifications of glass strips 20, before grinding, the direction of the spray head and the spray flow rate can also be adjusted to meet the grinding and cooling requirements of glass strips 20 of different specifications.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
