[0014] The present invention has the following beneficial effects: 1. The present invention is provided with an upper and lower polishing disc. When polishing a workpiece, the workpiece is placed on the lower polishing disc, and then the upper polishing disc is driven downward by the lifting assembly so that the upper polishing disc abuts against the top surface of the workpiece. Thereafter, the upper polishing disc and the lower polishing disc are driven to rotate in opposite directions by the rotary drive assembly, so that the upper polishing disc and the lower polishing disc polish the upper and lower surfaces of the workpiece respectively, thereby achieving simultaneous polishing of both sides of the workpiece, which is beneficial to improving the polishing efficiency of the workpiece.

[0022] Example 1 See also Figure 1-Figure 5 As shown, the present invention is a polishing device, comprising a frame 1, on which a polishing mechanism 2 and a liquid supply mechanism 3 are mounted. The polishing mechanism 2 comprises a rotary drive assembly, a lifting assembly, an upper polishing disc 24 and a lower polishing disc 25. The lower polishing disc 25 is rotatably mounted on the workbench of the frame 1, and the upper polishing disc 24 is mounted above the lower polishing disc 25 through the lifting assembly. The rotary drive assembly can drive the upper polishing disc 24 and the lower polishing disc 25 to rotate in opposite directions. The liquid supply mechanism 3 can deliver polishing liquid between the upper polishing disc 24 and the lower polishing disc 25; the top of the lower polishing disc 25 A jig assembly 4 is installed on the surface, and the jig assembly 4 includes a lifting frame, a planetary drive unit and multiple jig discs 41. Multiple jig discs 41 are installed on the top surface of the lower polishing disc 25 through the lifting frame. A positioning groove 42 for positioning the workpiece is provided on the jig disc 41. The lifting frame can drive the jig disc 41 upward when the upper polishing disc 24 and the lower polishing disc 25 perform chemical mechanical polishing on the workpiece, so that the bottom surface of the jig disc 41 is separated from the top surface of the lower polishing disc 25. The planetary drive assembly can drive the jig disc 41 to perform circular motion and synchronous rotation while polishing the workpiece.

[0023] When the polishing device is working, first, multiple workpieces to be polished are clamped and placed in the positioning grooves 42 on multiple jig discs 41, and at this time, the bottom surface of the workpiece is supported and placed on the top surface of the lower polishing disc 25. Then, the upper polishing disc 24 is driven downward by the lifting component, so that the upper polishing disc 24 abuts against the top surface of the workpiece. At the same time, the lifting frame drives the jig disc 41 upward, so that the bottom surface of the jig disc 41 is separated from the top surface of the lower polishing disc 25; then, the upper polishing disc 24 and the lower polishing disc 25 are driven to rotate in the opposite direction by the rotation drive component, so that the upper polishing disc 24 and the lower polishing disc 25 polish the upper and lower surfaces of the workpiece respectively, and the polishing liquid is transported between the upper polishing disc 24 and the lower polishing disc 25 through the liquid supply mechanism 3. At the same time, the planetary drive unit drives the jig disc 41 to perform circular motion while synchronously rotating, thereby driving the workpiece to perform planetary motion.

[0024] Among them, the upper and lower surfaces of the workpiece are polished at the same time by the upper polishing disc 24 and the lower polishing disc 25, so that the double-sided polishing of the workpiece can be achieved at the same time, which is beneficial to improving the polishing efficiency of the workpiece. The workpiece is positioned by the positioning groove 42 on the fixture disc 41 to prevent the workpiece from moving disorderly under the friction force during polishing, which is beneficial to improving the polishing effect of the workpiece. During polishing, the fixture disc 41 can be driven by the planetary drive unit to drive the workpiece to make circular motion and rotate itself, which can ensure that the two sides of the workpiece are evenly stressed, avoid excessive wear on one side, and further improve the polishing effect of the workpiece; lifting and lowering during polishing The frame drives the jig plate 41 upward, so that the bottom surface of the jig plate 41 is separated from the top surface of the lower polishing plate 25, thereby preventing the bottom surface of the jig plate 41 and the lower polishing plate 25 from continuous contact and friction with each other during polishing, which causes wear of the jig plate 41 and the lower polishing plate 25, and is beneficial to improving the service life of the jig plate 41 and the lower polishing plate 25. When polishing is completed and the upper polishing plate 24 is reset upward, the lifting frame drives the jig plate 41 to reset downward and move to the top surface of the lower polishing plate 25, so that the top of the workpiece can be exposed from the positioning groove 42 to a larger size, thereby making it convenient for the staff to take the workpiece out of the positioning groove 42 and put in a new workpiece.

[0026] Among them, before and after polishing, the upper polishing plate 24 is suspended above the lower polishing plate 25, so as to facilitate the taking and placing of the workpiece on the top surface of the lower polishing plate 25. During polishing, the lifting rod 23 is driven downward by the hydraulic cylinder 21, and the lifting rod 23 drives the upper bracket 22, the connecting rod 26, the lower bracket 27 and the upper polishing plate 24 to move downward synchronously until the bottom surface of the upper polishing plate 24 abuts against the top surface of the workpiece, and then the upper polishing plate 24 is driven to rotate by the rotation drive assembly to polish the workpiece.

The bottom end of the polishing disc 25 is connected to the lower disc driving ring gear 224 by meshing with the pinion 223; when the transmission shaft 216 rotates, it drives the lower disc driving gear 220 to rotate synchronously. At this time, the lower disc driving gear 220 engages to drive the lower disc driven gear 222 to rotate, thereby driving the lower disc driving shaft 221 and the pinion 223 to rotate. After that, the pinion 223 engages to drive the lower disc driving ring gear 224 to rotate, thereby driving the lower polishing disc 25 to rotate by the lower disc driving ring gear 224 to polish the bottom surface of the workpiece.

[0030] Specifically, the upper disk drive unit includes an upper disk transmission gear 217, an upper disk drive shaft 219 and a plurality of transmission blocks 210. The upper disk transmission gear 217 is fixedly mounted on the transmission shaft 216. The upper disk drive shaft 219 is rotatably mounted on the lower end of the frame 1. The upper disk drive shaft 219 is fixedly mounted with an upper disk driven gear 218 that is meshed and transmission-connected with the upper disk transmission gear 217. The top of the upper disk drive shaft 219 is fixedly mounted with an upper disk drive seat 225.

The plurality of transmission blocks 210 are all fixedly mounted on the inner ring of the lower bracket 27, and the transmission blocks 210 are respectively slidably mounted in the corresponding spline grooves 29. When the transmission shaft 216 rotates, it drives the upper disk transmission gear 217 to rotate synchronously, so that the upper disk transmission gear 217 engages and drives the upper disk driven gear 218 to rotate, thereby driving the upper disk drive shaft 219, the upper disk drive seat 225 and the spline shaft 28 to rotate synchronously, and when the spline shaft 28 rotates, it drives the lower bracket 27 to rotate synchronously through the spline groove 29 and the card connection transmission of the transmission block 210, thereby driving the upper polishing disk 24 to rotate through the lower bracket 27 to polish the top surface of the workpiece; and when the polishing is completed, the lifting assembly drives the lower bracket 27 and the upper polishing disk 24 to reset upward, and the lower bracket 27 drives the transmission block 210 to slide upward along the spline groove 29, so that the spline shaft 28 and the lower bracket 27 always maintain a circumferential locking connection through the cooperation of the transmission block 210 and the spline groove 29, so as to ensure that when the spline shaft 28 rotates, it can drive the lower bracket 27 and the upper polishing disk 24 to rotate and polish.

[0031] Example 4 See also Figure 1-Figure 5 As shown, the difference between this embodiment and the above embodiment is that the liquid supply mechanism 3 includes a polishing liquid supply conduit 31 and a liquid distribution annular groove 34, the liquid distribution annular groove 34 is fixedly installed on the outer ring of the upper bracket 22, and the bottom end of the liquid distribution annular groove 34 is connected to a plurality of liquid guide tubes 35, the outlet ends of the plurality of liquid guide tubes 35 are all embedded in the interior of the upper polishing plate 24 and connected to the bottom end of the upper polishing plate 24, the polishing liquid supply conduit 31 is fixedly connected to the lower end of the lifting rod 23 through the connecting frame, the bottom end of the polishing liquid supply conduit 31 is connected to a transfer pipe 32, one end of the transfer pipe 32 extends to the top of the liquid distribution annular groove 34, and is fixedly installed with a valve 33.

[0032] Among them, one end of the polishing liquid supply conduit 31 is connected to the polishing liquid storage tank. During polishing, the polishing liquid in the polishing liquid storage tank is pumped into the polishing liquid supply conduit 31 through a hydraulic pump, and then the polishing liquid is transported to the liquid distribution ring groove 34 through the transfer pipe 32 and the valve 33. Finally, the polishing liquid in the liquid distribution ring groove 34 is evenly transported to between the upper polishing plate 24 and the lower polishing plate 25 through multiple liquid guide pipes 35 to assist the polishing plate in polishing the workpiece. When the lower bracket 27 drives the upper polishing plate 24 to rotate for polishing, the lower bracket 27 drives the upper bracket 22 and the liquid distribution ring groove 34 to rotate synchronously through the connecting rod 26, so that each position in the liquid distribution ring groove 34 moves in turn through the bottom of the valve 33, so that the polishing liquid flowing out of the valve 33 can be evenly transported and distributed in the liquid distribution ring groove 34, thereby improving the uniformity of polishing liquid transportation and thus improving its polishing effect.

[0033] Example 5 See also Figure 4-Figure 6 As shown, the difference between this embodiment and the above embodiment is that the planetary drive unit includes an inner ring gear 43, an intermediate ring gear 45 and a plurality of planetary ring gears 44.

[0034] When the upper disk drive seat 225 rotates and drives the upper polishing disk 24 to rotate and polish, the upper disk drive seat 225 drives the intermediate ring gear 45 to rotate synchronously. At this time, the intermediate ring gear 45 drives the multiple planetary ring gears 44 on its outer ring to rotate synchronously, and the planetary ring gears 44 rotate and mesh with the inner ring gear 43 to make the planetary ring gears 44 move in a circular motion along the inner ring gear 43, and then the planetary ring gears 44 drive the jig disk 41 and the workpiece in its positioning groove 42 to rotate and move in a circular motion, so that the polishing of the workpiece is more uniform, and the polishing effect of the workpiece is improved.

[0035] Example 6 See also Figure 4-Figure 6 、 Figure 11-13 As shown, the difference between this embodiment and the above embodiment is that the lifting frame includes a lifting slip ring 46, a ring sleeve 47 and a pushing lifting unit. The lifting slip ring 46 is slidably installed on the outer ring of the intermediate gear ring 45, and the inner ring of the lifting slip ring 46 is fixedly installed with a clamping block 415 that is slidably engaged with the tooth groove of the intermediate gear ring 45.

[0036] When the upper polishing plate 24 is driven downward for polishing by the lifting assembly, the pushing lifting unit drives the lifting slip ring 46 upward, thereby driving the ring sleeve 47 and the jig plate 41 upward, so that the bottom surface of the jig plate 41 is separated from the top surface of the lower polishing plate 25, thereby preventing the bottom surface of the jig plate 41 from being in continuous contact and friction with the lower polishing plate 25 during polishing, which causes wear of the jig plate 41 and the lower polishing plate 25, which is beneficial to improving the service life of the jig plate 41 and the lower polishing plate 25, and the lifting slip ring 46 and the ring sleeve 47 cooperate to support and limit the jig plate 41, improve the stability of the movement of the jig plate 41 and the workpiece, thereby improving the polishing effect of the workpiece; and when polishing is completed and the upper polishing plate 24 is reset upward, the pushing lifting unit drives the jig plate 41 to reset downward and move to the top surface of the lower polishing plate 25, so that the top of the workpiece can be exposed from the positioning groove 42 to a larger size, thereby facilitating the staff to take the workpiece out of the positioning groove 42 and put in a new workpiece.

[0037] Specifically, the pushing and lifting unit includes a slide groove 49 and a pushing wedge block 413. The slide groove 49 is opened on the outer ring of the top surface of the middle gear ring 45. The inside of the slide groove 49 is slidably installed with a push rod 48. The lower end of the slide groove 49 is fixedly installed with a limit plate 410. The lower end of the push rod 48 is abutted with a return spring 411. The bottom end of the push rod 48 is fixedly installed with an inverted frustum 412. The pushing wedge block 413 is slidably clamped on one side of the bottom end of the slide groove 49. One end of the pushing wedge block 413 slides and abuts with the conical surface of the frustum 412 through an inclined surface, and the other end of the pushing wedge block 413 is slidably abutted with a lifting wedge block 414 through an inclined surface. The outer end of the lifting wedge block 414 is fixedly installed with a support seat 416 abutted and supported on the bottom surface of the clamping block 415.

[0038] When the lower bracket 27 drives the upper polishing disc 24 downward for polishing, the lower bracket 27 pushes the push rod 48 downward. At this time, the push rod 48 drives the bottom cone 412 downward, so that the bottom cone 412 pushes the pushing wedge block 413 outward. At the same time, the pushing wedge block 413 pushes the lifting wedge block 414 upward, so that the lifting wedge block 414 pushes the block 415 upward through the support seat 416, and then the block 415 drives the lifting slip ring 46 to move upward. At the same time, the lifting slip ring 46 drives the ring sleeve 47 and the jig plate 41 upward, so that the jig plate 41 is separated from the lower polishing plate 25; and when polishing is completed, the lower bracket 27 drives the upper polishing plate 24 upward and no longer abuts against the push rod 48, the push rod 48 is reset upward under the elastic force of the reset spring 411, and at the same time, the jig plate 41, the ring sleeve 47 and the lifting slip ring 46 are reset downward under the action of their own gravity, so that the jig plate 41 falls back to the surface of the lower polishing plate 25 to facilitate the removal of the polished workpiece.

[0039] Example 7 This embodiment discloses a method for polishing a blue glass filter, and the specific steps are as follows: First, multiple blue glass filters to be polished are clamped and placed in the positioning grooves 42 on multiple jig plates 41, with the bottom surfaces of the blue glass filters supported and placed on the top surface of the lower polishing plate 25. Then, the upper polishing plate 24 is driven downward by the lifting assembly, so that the upper polishing plate 24 abuts the top surface of the blue glass filters. At the same time, the lifting frame drives the jig plate 41 upward, separating the bottom surface of the jig plate 41 from the top surface of the lower polishing plate 25. Then, the upper polishing plate 24 and the lower polishing plate 25 are driven to rotate in opposite directions by the rotary drive assembly, so that the upper polishing plate 24 and the lower polishing plate 25 polish the upper and lower surfaces of the blue glass filter respectively, and the polishing liquid is transported between the upper polishing plate 24 and the lower polishing plate 25 through the liquid supply mechanism 3. At the same time, the planetary drive unit drives the jig plate 41 to perform circular motion while rotating synchronously, thereby driving the blue glass filter to perform planetary motion.
