Description

Technical Field

[0001] The present invention relates to the technical field of technical surface treatment equipment, and particularly to an optical cover plate surface treatment device. Background Art

[0002] Optical cover plates are generally made by cutting glass materials through a cutting process. After cutting, there may be burrs or scratches on the surfaces of the optical cover plates, such as the top surface, bottom surface, four sides, and four corners. Therefore, enterprises usually perform grinding treatment on the surfaces of the optical cover plates after cutting.

[0003] Since the areas where the optical cover plates need surface treatment are in different positions, currently, most enterprises use multiple devices to separately grind the top and bottom surfaces, as well as the four sides and four corners of the optical cover plates. This not only results in high processing costs and a large occupied area for the processing site, but also requires the optical cover plates to be processed to be transferred between different processing devices, reducing the overall work efficiency. Summary of the Invention

[0004] One advantage of the present invention is to provide an optical cover plate surface treatment device. When treating the surface of the optical cover plate, based on the position to be treated of the optical cover plate, a polishing mold, an edge grinding mold, or a corner grinding mold is adaptively replaced on the rotary clamping mechanism, and at the same time, the position of the polishing shaft is correspondingly adjusted so that the polishing disc can polish the position to be treated of the optical cover plate on the mold. This enables the optical cover plate surface treatment device to process different positions of the optical cover plate, effectively saving equipment costs, reducing the occupied area of the equipment, and improving the overall work efficiency. The overall structure is simple, the failure rate is low, it is easy to operate, and it is convenient for disassembly, installation, and maintenance.

[0005] One advantage of the present invention is to provide an optical cover plate surface treatment device, in which the horizontal adjustment component can detect the levelness of the fixing plate after replacing different molds, ensuring that the mold and the optical cover plate on the mold can be correctly placed, and thus effectively ensuring the quality of the optical cover plate surface treatment.

[0006] One advantage of the present invention is to provide an optical cover plate surface treatment device, in which there are two polishing shafts, and the positions of the polishing shafts on the mounting plate can be adjusted.

Detailed implementation manners

[0036] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description can be applied to other implementation schemes, variant schemes, improvement schemes, equivalent schemes, and other technical schemes that do not depart from the spirit and scope of the present invention.

[0037] Those skilled in the art should understand that in the disclosure of the specification, the orientation or positional relationship indicated by terms such as "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0038] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as limiting the quantity.

[0039] Referring Figures 1 to 10 , an optical cover plate surface treatment device according to a preferred embodiment of the present invention will be described in detail below. The optical cover plate surface treatment device includes a base 10, a mold assembly, and a surface treatment assembly. A rotary clamping mechanism is provided on the top of the base 10. The mold assembly includes at least two of a polishing mold 21, an edge grinding mold 22, and a corner grinding mold 23, such as the polishing mold 21 and the edge grinding mold 22, the edge grinding mold 22 and the corner grinding mold 23, the polishing mold 21 and the corner grinding mold 23, or may also include the polishing mold 21, the edge grinding mold 22, and the corner grinding mold 23 at the same time. The surface treatment assembly includes a support frame 31, a lifting mechanism 32, a rotating element 33, a polishing shaft 34, and a polishing disc 35. The support frame 31 extends above the mold assembly. The lifting mechanism 32 is arranged on the support frame 31. At the same time, the rotating element 33 is connected to the output end of the lifting mechanism 32 through a mounting plate 36, so that it can be driven by the lifting mechanism 32 to move vertically in a fixed direction. The polishing shaft 34 extends in the vertical direction and faces the mold assembly above the mold assembly. At the same time, the polishing shaft 34 is connected to the rotating element 33 in a manner that can be driven to rotate in a fixed direction, and the position of the polishing shaft 34 in the horizontal direction is changeable. At the same time, the polishing disc 35 is coaxially arranged at the bottom of the polishing shaft 34;

[0040] In this way, since the positions of the polishing shaft 34 and the polishing disc 35 can be changed, when processing different positions on the surface of the optical cover plate, the mold on the rotary clamping mechanism can be directly replaced. For example, when processing the top and bottom surfaces of the optical cover plate, the polishing mold 21 is installed on the rotary clamping mechanism, and the position of the polishing shaft 34 is horizontally moved adaptively so that the polishing disc 35 faces the top of the horizontally placed optical cover plate. When processing the four peripheral edges of the optical cover plate, the edge grinding mold 22 is installed on the rotary clamping mechanism, and the position of the polishing shaft 34 is horizontally moved adaptively so that the polishing disc 35 faces the side edge of the vertically placed optical cover plate. When processing the four corners of the optical cover plate, the corner grinding mold 23 is installed on the rotary clamping mechanism, and the position of the polishing shaft 34 is horizontally moved adaptively so that the polishing disc 35 faces the four corners of the optical cover plate horizontally placed in the middle.

[0041] Therefore, when processing different positions on the surface of the optical cover plate, only the position of the polishing shaft 34 needs to be changed and the corresponding mold needs to be replaced. Furthermore, the optical cover plate surface treatment device provided by the present application can perform any two or all three of polishing treatment, edge grinding treatment, and corner grinding treatment on the optical cover plate at the same time, greatly saving the investment cost of the optical cover plate surface treatment equipment. When performing different surface treatments, there is no need to transfer between different devices, improving the work efficiency. In addition, since the position of the polishing shaft 34 can be adjusted and the polishing disc 35 can also be replaced, different specifications of optical cover plates can be processed by this surface treatment device, and the applicable range is wider. In addition, one device can perform multiple tasks at the same time, effectively reducing the floor area occupied by the surface treatment equipment. The optical cover plate surface treatment device provided by the present application has a simple overall structure, is easy to process, manufacture, and maintain, and has a low failure rate.

[0042] More specifically, in combination with Figure 3 and Figure 4 , the polishing mold 21 includes a first body 211 adapted to be fixed on the rotary clamping mechanism. A first circular groove 201 is provided at the center of the top of the first body 211. At the same time, a plurality of flat grooves 202 adapted to horizontally fix the optical cover plate are arranged in an annular array in the first circular groove 201 of the first body 211.

[0043] In combination with Figure 5 and Figure 6 , the edge grinding mold 22 includes a second body 221 adapted to be fixed on the rotary clamping mechanism. A second circular groove 203 is provided at the center of the top of the second body 221. At the same time, a plurality of vertical grooves 204 adapted to vertically fix the optical cover plate are arranged in an annular array in the second circular groove 203 of the second body 221.

[0044] Further preferably, the edge grinding die 22 further includes a moving plate 222 and a static plate 223 disposed in the vertical groove 204, extending in the vertical direction and cooperating with each other. A set screw 225 is disposed on a side of the moving plate 222 away from the static plate 223. At the same time, the set screw 225 is threadedly connected to a side wall of the vertical groove 204. Thus, when the set screw 225 is rotated, based on a threaded engagement relationship between the set screw 225 and the side wall, the moving plate 222 can be loosened or squeezed correspondingly, and then the optical cover plate can be fixed through the cooperation between the moving plate 222 and the static plate 223 during the working process.

[0045] Further preferably, protective layers or protective structures, such as soft materials like rubber, are provided on opposite surfaces of the moving plate 222 and the static plate 223 to prevent damage to the optical cover plate when fixing the optical cover plate.

[0046] In addition, in combination with Figure 7 and Figure 8 , the chamfering die 23 includes a third body 231 adapted to be fixed on the rotary clamping mechanism. A third circular groove 205 is provided at a central position on the top of the third body 231. At the same time, a limiting structure is provided at the center of the third circular groove 205 of the third body 231. The limiting structure is configured to be adapted to limit the edge of the optical cover plate and expose four corners of the optical cover plate, so that the four exposed corners of the optical cover plate can be processed by the polishing disc on the basis of effectively fixing the optical cover plate.

[0047] Further preferably, the limiting structure includes a pressing plate 232 and four limiting members 233. The four limiting members 233 surround to form a quadrilateral space adapted to limit the edge of the optical cover plate. The limiting member 233 is preferably implemented as a plate-shaped member, so as to form a relatively large contact area when fitting the four sides of the optical cover plate, so as to improve the limiting stability of the limiting member 233 on the optical cover plate. The pressing plate 232 cooperates with the four limiting members 233 respectively to fix the optical cover plate on the top of the optical cover plate after the optical cover plate is placed in the quadrilateral space. More specifically, the pressing plate 232 is a cross-shaped plate, and strip-shaped holes for sleeving the limiting members 233 are provided on four extended plates, and then when the optical cover plate is placed in the quadrilateral space, it can press on the optical cover plate to fix the optical cover plate.

[0048] As a preferred embodiment, the rotary clamping mechanism includes a chuck 11 and a rotary motor. The rotary motor is fixedly arranged in the base 10, and the output end of the rotary motor extends vertically upward. The chuck 11 includes a chuck body and a plurality of jaws. The bottom of the chuck body is coaxially and fixedly connected to the output end of the rotary motor, so that the chuck 11 can be driven by the rotary motor to rotate directionally. The plurality of jaws are arranged on the top of the chuck body in a manner that enables radial movement and cooperation, and are used to fix the first body 211, the second body 221, or the third body 231.

[0049] It should be noted that the chuck 11 belongs to a common mechanical device for clamping workpieces, and the workpiece is fixed by the cooperation of a plurality of jaws evenly distributed on the chuck body. The specific moving structure of the jaws will not be elaborated in detail.

[0050] Further preferably, the lifting mechanism 32 includes a lifting motor 321, a lead screw 322, and a slider 323 threadedly engaged with the lead screw 322. The lifting motor 321 is arranged vertically and fixed on the support frame 31. The lead screw 322 is coaxially connected to the rotating end of the lifting motor 321 below the lifting motor 321, so that the lead screw 322 can be driven by the lifting motor 321 to rotate directionally. A guide rail 311 extending vertically and cooperating with the slider 323 is arranged on the support frame 31. At the same time, the mounting plate 36 is an L-shaped plate, and the vertical portion of the mounting plate 36 is fixedly connected to the slider 323, while the horizontal portion of the mounting plate 36 is supported and connected to the bottom of the rotating element 33. In this way, based on the cooperation relationship between the slider 323 and the guide rail 311, when the lifting motor 321 operates and drives the lead screw 322 to rotate, the slider 323 threadedly engaged with the lead screw 322 will move vertically in a directional manner, and then drive the rotating element 33 to move up and down through the mounting plate 36, so as to ensure that the polishing disc 35 can move up and down to an appropriate height to perform corresponding surface treatment on the optical cover plate.

[0051] Further preferably, the surface treatment assembly further includes a transmission structure, wherein the transmission structure includes a transmission wheel 37, a transmission belt 38 and a tensioning wheel 39. The transmission wheel 37 is connected to the rotating end of the rotating element 33 through the transmission belt 38, so that the rotating element 33 can drive the transmission wheel 37 to rotate synchronously through the transmission belt 38. The polishing shaft 34 is embedded in the wheel cavity of the transmission wheel 37 in a manner of passing through the mounting plate 36 below the mounting plate 36. At the same time, the tensioning wheel 39 is arranged on the mounting plate 36 in a manner that it can be moved to tension the transmission belt 38, so as to drive the polishing shaft 34 to rotate synchronously through the rotating element 33 in a belt transmission manner. The change of the installation position of the tensioning wheel 39 can correspondingly adjust the tightness of the transmission belt 38, and further facilitate the installation of the transmission wheel 37 and the adjustment of the positions of the transmission wheel 37 and the polishing shaft 34.

[0052] As a preferred embodiment, both the polishing shaft 34 and the polishing disc 35 are implemented as two. The two polishing shafts 34 are arranged on the mounting plate 36 in a manner that the relative distance between them can be adjusted. When performing surface treatment on the optical cover plate, by appropriately adjusting the distance between the two polishing shafts 34, the two polishing discs 35 can be driven to perform synchronous grinding treatment, thereby effectively improving the surface treatment efficiency and saving time.

[0053] In addition, a limiting plate 361 is arranged at the bottom of the mounting plate 36. The limiting plate 361 is detachably connected to the mounting plate 36 in a manner that it can move along the moving direction of the polishing shaft 34. At the same time, a bearing for sleeving the polishing shaft 34 is fixedly arranged in the limiting plate 361.

[0054] More specifically, a plurality of strip holes 301 are arranged in parallel on the mounting plate 36 along the moving direction of the two polishing shafts 34. The strip hole 301 near the middle is used to place the polishing shaft 34, and the strip holes 301 near both sides are used to cooperate with the limiting plate 361 to fix the polishing shaft 34. For example, after the limiting plate 361 moves in place, the limiting plate 361 is fixed to the mounting plate 36 through bolts cooperating with the strip holes 301. Since the polishing shaft 34 is arranged in the bearing in a manner that it can rotate, with the change of the position of the limiting plate 361, the position of the polishing shaft 34 changes accordingly.

[0055] Further preferably, in combination with Figure 9 and Figure 10, the optical cover plate surface treatment device further includes a horizontal adjustment assembly 40, wherein the horizontal adjustment assembly 40 includes a fixing plate 41, an adjustment mechanism, a level gauge, and a fixing seat 42. The fixing plate 41 is used to connect the first body 211, the second body 221, or the third body 231, generally connected by fasteners such as bolts. The fixing plate 41 is connected to the fixing seat 42 through the adjustment mechanism in a manner that can adjust the levelness. At the same time, a fixing shaft 421 adapted to be inserted into a plurality of the jaws is provided at one end of the fixing seat 42 away from the fixing plate 41. In this way, since the fixing seat 42 is inserted into the chuck 11 through the fixing shaft 421, when it is necessary to replace different molds for corresponding surface treatment, the levelness of the fixing plate 41 relative to the fixing seat 42 can be adjusted to ensure that the replaced mold is accurately installed in place, thereby ensuring the surface treatment accuracy of the optical cover plate. In addition, the level gauge (such as a level, a theodolite, a total station, etc.) is arranged on the base 10 and faces the fixing plate 41 to detect whether the levelness of the fixing plate 41 is qualified. The levelness of the fixing seat 42 is ensured by the chuck 11. Since the horizontal adjustment assembly does not need to be removed during the mold replacement process, the levelness of the fixing seat 42 itself basically does not change.

[0056] Further preferably, the adjusting mechanism includes a spherical adjusting member 431, a connecting member 432, a turbine 433 and a rotating rod 434. One end of the spherical adjusting member 431 is fixedly connected to the fixing plate 41, and the other end of the spherical adjusting member 431 is of a spherical structure. A spherical groove 401 matching the spherical structure is provided at one end of the fixed seat 42 away from the fixed shaft 421. One end of the connecting member 432 is provided with a ball head 4321. A connecting channel 402 extending in the vertical direction is provided at the central position of the spherical adjusting member 431, and a limiting groove 403 matching the ball head 4321 is provided in the connecting channel 402. At the same time, the connecting member 432 penetrates through the connecting channel 402 and extends into the fixed seat 42, and an external thread is provided at the lower part. At the same time, a clamping groove 404 is provided at the bottom of the connecting member 432. In addition, a clamping plate 422 matching the clamping groove 404 is provided in the fixed seat 42. At the same time, an internal thread matching the external thread is provided in the central hole of the turbine 433, and the rotating rod 434 extends horizontally and is inserted into the fixed seat 42, and a worm structure 4341 matching the turbine 433 is provided at the inner end of the rotating rod 434. Based on the matching relationship between the turbine 433 and the worm structure 4341, the turbine 433 can be driven to rotate correspondingly by rotating the rotating rod 434. In addition, based on the limiting relationship formed by the clamping groove 404 and the clamping plate 422, when the turbine 433 rotates, the connecting member 432 will correspondingly rise or fall in the central hole of the turbine 433, so that the connecting member 432 can tighten the spherical adjusting member 431 and stably hold it in the spherical groove 401, so as to ensure the levelness of the fixing plate 41 based on the matching of the spherical structure and the spherical groove 401. In addition, it should be emphasized that: the rotating rod 434 drives the turbine 433 to rotate, and then the turbine 433 drives the connecting member 432 to move up and down. There is a positive drive relationship among the rotating rod 434, the turbine 433 and the connecting member 432, and there will be no reverse drive situation, that is, there will be no situation where the connecting member 432 moves up and down to drive the turbine 433 to rotate. That is to say, the adjusting mechanism provided by the present application has the function of reverse self-locking. In this way, even if there is a slight deviation in the levelness of the fixing plate 41, the fixing plate 41 can be restored to the levelness by slightly colliding the fixing plate 41 with an external force. During this period, under the tension of the connecting member 432 on the spherical adjusting member 431, the adjusting mechanism can still maintain a stable working state to ensure the stability of the mold for processing the optical cover plate.

[0057] Further preferably, a tapered avoidance hole 405 is provided at the lower part of the spherical adjusting member 431 in the connection channel 402. At the same time, the tapered avoidance hole 405 is located below the limit groove 403 to prevent the spherical adjusting member 431 from affecting the operation of the connecting member 432 during the process of adjusting the levelness.

[0058] It should be noted that the terms "first", "second" and "third" in the present invention are only for descriptive purposes, do not represent any order, and should not be construed as indicating or implying relative importance. These terms can be interpreted as names.
