Description

Technical Field

[0001] This invention relates to a polishing device, and more particularly to a polishing device for the surface of an LED lampshade. Background Technology

[0002] After LED lampshades are manufactured, their surfaces will have many burrs. To ensure the aesthetics and quality of the LED lampshades, the surface needs to be polished to remove the burrs and improve their appearance.

[0003] Chinese patent CN216681577U discloses an LED lampshade polishing device, belonging to the field of lampshade manufacturing technology. It includes a worktable, a workpiece positioning component, a polishing and chip removal component, and a rapid cleaning component. The workpiece positioning component is installed on top of the worktable, and the polishing and chip removal component is installed behind the workpiece positioning component, with its top extending above the workpiece positioning component. The rapid cleaning component is installed to the left of the workpiece positioning component and the polishing and chip removal component. Although this patent can polish the surface of LED lampshades using a polishing machine, the polishing blades are relatively small and their positions are fixed, making it difficult to thoroughly polish the surface of the LED lampshade, thus affecting the polishing effect.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, an LED lampshade surface polishing device is proposed that can perform comprehensive polishing of the LED lampshade surface and improve the polishing effect. Summary of the Invention

[0005] In order to overcome the shortcomings of the above-mentioned patents, which can polish the surface of LED lampshades with a polishing machine, but whose polishing blades are relatively small and fixed in position, making it difficult to polish the surface of LED lampshades comprehensively and affecting the polishing effect, the present invention provides an LED lampshade surface polishing device that can polish the surface of LED lampshades comprehensively and improve the polishing effect.

[0006] This invention is achieved through the following technical means:

[0007] An LED lampshade surface polishing device includes a worktable, a baffle plate, a U-shaped plate, a lifting plate, a placement seat, an electric screw, and a cover. The baffle plate is fixed to the top of the worktable. The U-shaped plate is fixed to the middle of the left side of the top of the worktable. The lifting plate is slidably connected to the inner side of the U-shaped plate. The cover is rotatably threaded through the right side of the lifting plate. The placement seat for placing the LED lampshade is fixed to the middle of the right side of the top of the worktable. The placement seat is located directly below the cover. An electric screw for moving the lifting plate is provided between the middle of the U-shaped plate and the worktable. The electric screw is threadedly connected to the lifting plate. The device also includes polishing wheels, a drive mechanism, and a liquid supply mechanism. Polishing wheels for polishing the surface of the LED lampshade are rotatably threaded through the middle of the top and the upper front and rear sides of the cover. The lifting plate is provided with a drive mechanism for rotating the cover. The cover is provided with a liquid supply mechanism for spraying polishing liquid.

[0008] Further explanation: The drive mechanism includes a servo motor, gears and a gear ring. Gears are fixedly mounted on the outer ends of the grinding wheels on both the front and rear sides. A gear ring for driving the gears to rotate is fixedly connected to the right side of the lifting plate. The gear ring meshes with the gears. A servo motor is fixedly connected to the bottom left side of the lifting plate. The output shaft of the servo motor is connected to the upper part of the cover through a synchronous belt assembly.

[0009] Further explanation: The liquid supply mechanism includes a mounting plate, a liquid supply pipe, and a liquid storage tank. A liquid storage tank for collecting the dropped polishing liquid is fixedly connected to the right side of the workbench. Mounting plates are fixedly connected to the right sides of both the front and rear sides of the lifting plate. A liquid supply pipe for spraying polishing liquid is fixedly connected between the inner ends of the front and rear mounting plates. The liquid supply pipe is in contact with the bottom of the cover.

[0010] Further explanation includes a positioning mechanism for fixing the LED lampshade. The positioning mechanism includes an air cushion, a double-rod piston cylinder, a first spring, an air guide pipe, a diverter pipe, and a return spring. Six air cushions for fixing the LED lampshade are fixedly connected to the upper part of the placement seat at even intervals along the circumference. A diverter pipe is fixedly connected between the middle of the right side of the worktable and the placement seat. The six air outlets of the diverter pipe are fixedly connected to and communicate with the six air cushions respectively. A double-rod piston cylinder is slidably connected to the inner side of the molded plate. The double-rod piston cylinder is located below the lifting plate. The upper part of the front and rear sides of the double-rod piston cylinder is connected to the bottom of the molded plate with a first spring. The lifting plate moves downward and contacts the piston rod of the double-rod piston cylinder. An air guide pipe is connected to the lower left side of the double-rod piston cylinder. The tail end of the air guide pipe passes through the worktable and is fixedly connected to and communicates with the lower part of the diverter pipe. Two return springs are connected between the upper part of the piston rod of the double-rod piston cylinder and the top of the cylinder body.

[0011] Further explanation includes a release mechanism for limiting the LED lampshade. The release mechanism includes a positioning plate, a locking block, a second spring, a limiting rod, a release upright, and a third spring. A release upright for limiting the LED lampshade is slidably connected to the top center of the cover. A third spring is connected between the lower part of the release upright and the inner side of the cover. A positioning plate is fixed to the upper center of the right side of the molded plate. The right side of the positioning plate is slidably connected to the release upright. A limiting rod is slidably connected to the left side of the positioning plate. The bottom right end of the limiting rod is rotatably connected to the top of the release upright. A locking block for limiting the limiting rod is symmetrically rotatably connected to the middle of the outer top of the molded plate. A second spring is connected between the outer sides of the inner top of the locking blocks on both the front and rear sides and the inner side of the molded plate.

[0012] Further explanation includes an air jet pipe and a mounting bracket. Mounting brackets are fixed to the front and rear right sides inside the baffle. An air jet pipe is fixed between the inner ends of the front and rear mounting brackets to spray air to remove residual polishing fluid and debris from the LED lampshade.

[0013] Further explanation includes a filter plate, which is circumferentially fixed to the lower inner side of the storage tank to filter impurities in the polishing fluid.

[0014] Further explanation includes the presence of anti-slip rubber sheets, which are symmetrically fixed to the bottom of the workbench.

[0015] The significant advancement of this invention lies in:

[0016] 1. Place the LED lampshade on the mounting base, then connect the polishing fluid to the external supply pipe. Start the servo motor to rotate, which will cause the cover to drive the polishing wheel to rotate. The polishing wheel rotates on its own through the gear ring. Then start the electric screw to rotate forward, which will cause the lifting plate to move the cover downward. The cover will drive the polishing wheel downward to contact the LED lampshade. The rotation of the polishing wheel can polish the surface of the LED lampshade, thereby improving the polishing effect.

[0017] 2. Under the action of the positioning mechanism, whenever the lifting plate starts to move the cover downward, the positioning mechanism can further fix the LED cover, which can prevent the LED cover from becoming loose and affecting the grinding of the grinding wheel, thereby improving the stability of the LED cover placement.

[0018] 3. Under the action of the disengagement mechanism, whenever the cover moves upward and drives the grinding wheel upward, the disengagement mechanism can limit the LED cover, so that the LED cover is disengaged from the grinding wheel. This can prevent the grinding wheel from driving the LED cover upward and causing it to fall and be damaged, thus ensuring that the LED cover can be smoothly disengaged from the grinding wheel.

[0030] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0031] Example 1

[0032] An LED lampshade surface polishing device includes a worktable 1, a baffle plate 2, an anti-slip rubber plate 21, a U-shaped plate 3, a lifting plate 4, a placement seat 5, an electric lead screw 6, a cover 7, a polishing wheel 8, a drive mechanism 9, and a liquid supply mechanism 10. (Please refer to...) Figures 1-4 As shown, anti-slip rubber plates 21 are symmetrically fixed to the bottom of the workbench 1. A baffle plate 2 is installed on the top of the workbench 1 by bolt connection. A U-shaped plate 3 is fixed to the middle of the left side of the top of the workbench 1. A lifting plate 4 is slidably connected to the inside of the U-shaped plate 3. A cover 7 is rotatably inserted through the right side of the lifting plate 4. Grinding wheels 8 are rotatably inserted through the middle of the top and the upper parts of the front and rear sides of the cover 7. When the grinding wheels 8 rotate, they can grind the surface of the LED lampshade. A pad is fixed to the middle of the right side of the top of the workbench 1. The placement seat 5 is used to place the LED lamp cover. The placement seat 5 is located directly below the cover 7. An electric screw 6 is set between the middle of the U-shaped plate 3 and the worktable 1. The electric screw 6 is threadedly connected to the lifting plate 4. When the electric screw 6 is started, it can drive the lifting plate 4 to move. The lifting plate 4 is equipped with a drive mechanism 9. When the drive mechanism 9 is operating, it can drive the cover 7 to rotate. The cover 7 is equipped with a liquid supply mechanism 10, which can spray out polishing liquid.

[0033] The drive mechanism 9 includes a servo motor 91, a gear 92, and a gear ring 93. Please refer to [link / reference]. Figure 2 and Figure 3 As shown, gears 92 are fixedly mounted on the outer ends of the grinding wheels 8 on both the front and rear sides. A gear ring 93 is installed on the right side of the lifting plate 4 by welding. The gear ring 93 meshes with the gear 92. When the gear 92 rotates, the gear ring 93 can drive the gear 92 to rotate. A servo motor 91 is installed on the bottom left side of the lifting plate 4 by bolt connection. The output shaft of the servo motor 91 is connected to the upper part of the cover 7 by a synchronous belt assembly.

[0034] The liquid supply mechanism 10 includes a mounting plate 101, a liquid supply pipe 102, and a liquid storage tank 103. Please refer to [link / reference]. Figure 2 and Figure 4 As shown, a liquid storage tank 103 is fixedly connected to the right side of the workbench 1. The liquid storage tank 103 can collect the dropped polishing fluid. The right sides of the front and rear sides of the lifting plate 4 are equipped with mounting plates 101 by welding. A liquid supply pipe 102 is fixedly connected between the inner ends of the mounting plates 101 on the front and rear sides. The liquid supply pipe 102 is in contact with the bottom of the cover 7. When the polishing fluid is discharged into the liquid supply pipe 102, the liquid supply pipe 102 can spray out the polishing fluid.

[0035] First, fix the LED lampshade on the mounting base 5. Then, start the servo motor 91. The servo motor 91 drives the cover 7 to rotate via the synchronous belt assembly. The rotation of the cover 7 drives the three grinding wheels 8 to rotate. The rotation of the three grinding wheels 8 is achieved by the rotation of the gear ring 93. Then, connect the grinding fluid to the external supply pipe 102. Next, start the electric screw 6 to rotate forward. The forward rotation of the electric screw 6 drives the lifting plate 4 to move downward. The downward movement of the lifting plate 4 drives the cover 7 to move downward. The downward movement of the cover 7 drives the grinding wheels 8 to move downward. When the grinding wheels 8 contact the surface of the LED lampshade, turn off the electric screw 6. The lifting plate 4 stops driving the cover 7 to move downward. The grinding wheels 8... The downward movement stops, and the cover 7 covers the LED lampshade. The grinding wheel 8 rotates and spins to thoroughly grind the surface of the LED lampshade, thereby improving the grinding effect. During the grinding process, the cover 7 can prevent the debris generated during the grinding process from being scattered to the surrounding environment and affecting it. At the same time, the grinding fluid is discharged into the supply pipe 102, and the supply pipe 102 sprays the grinding fluid onto the surface of the LED lampshade. The grinding wheel 8 continues to grind the surface of the LED lampshade through the grinding fluid. The used grinding fluid falls onto the workbench 1, and the grinding fluid on the workbench 1 flows into the storage tank 103 for collection. Due to the effect of the anti-slip rubber plate 21, the device can be used more stably. After the surface of the LED lampshade is polished, stop the discharge of polishing fluid into the supply pipe 102, turn off the servo motor 91, and stop the cover 7 from driving the polishing wheel 8 to rotate. The polishing wheel 8 stops rotating through the gear ring 93. Then start the electric screw 6 to reverse and drive the lifting plate 4 to move upward and reset. The lifting plate 4 resets and drives the cover 7 to move upward and reset. The cover 7 moves upward and resets and drives the polishing wheel 8 to move upward and reset. The polishing wheel 8 resets and disengages from the LED lampshade. Turn off the electric screw 6, remove the polished LED lampshade from the placement seat 5, and then place the collection container directly below the liquid storage tank 103. Open the liquid storage tank 103 and discharge the polishing fluid in the liquid storage tank 103 into the collection container. After all the polishing fluid has been discharged, close the liquid storage tank 103.

[0036] Example 2

[0037] Based on Embodiment 1, a positioning mechanism 11 is also included. The positioning mechanism 11 includes an air cushion 111, a double-rod piston cylinder 112, a first spring 113, an air guide tube 114, a diverter tube 115, and a return spring 116. Please refer to [link to relevant documentation]. Figures 5-7As shown, six air cushions 111 are fixedly attached to the upper part of the placement seat 5 at even intervals along the circumference. When the air cushions 111 expand, they can fix the LED lamp cover. A diversion pipe 115 is fixedly connected between the middle right side of the worktable 1 and the placement seat 5. The six air outlets of the diversion pipe 115 are fixedly connected to and communicate with the six air cushions 111 respectively. A double-rod piston cylinder 112 is slidably connected to the inner side of the molded plate 3. The double-rod piston cylinder 112 is located below the lifting plate 4. The upper part of the front and rear sides of the double-rod piston cylinder 112 is connected to the bottom of the molded plate 3 with a first spring 113. The lifting plate 4 moves downward and contacts the piston rod of the double-rod piston cylinder 112. A guide pipe 114 is connected to the lower left side of the double-rod piston cylinder 112. The tail end of the guide pipe 114 passes through the worktable 1 and is fixedly connected to and communicates with the lower part of the diversion pipe 115. Two return springs 116 are connected between the upper part of the piston rod of the double-rod piston cylinder 112 and the top of the cylinder body.

[0038] It also includes a release mechanism 12, which includes a positioning plate 121, a locking block 122, a second spring 123, a limiting rod 124, a release upright 125, and a third spring 126. Please refer to [link / reference needed]. Figure 5 , Figure 8 and Figure 9 As shown, a release rod 125 is slidably connected to the top center of the cover 7. The release rod 125 can limit the LED lampshade. A third spring 126 is connected between the lower part of the release rod 125 and the inner side of the cover 7. A positioning plate 121 is installed in the middle of the upper right side of the molded plate 3 by bolt connection. The right side of the positioning plate 121 is slidably connected to the release rod 125. A limit rod 124 is slidably connected to the left side of the positioning plate 121. The bottom right end of the limit rod 124 is rotatably connected to the top of the release rod 125. A locking block 122 is symmetrically rotatably connected to the middle of the outer top of the molded plate 3. When the limit rod 124 moves downward and contacts the locking block 122, the locking block 122 can limit the limit rod 124. A second spring 123 is connected between the outer side of the inner top of the locking blocks 122 on both the front and rear sides and the inner side of the molded plate 3.

[0039] When the electric screw 6 rotates forward, driving the lifting plate 4 to move downward, the lifting plate 4 moves downward and contacts the piston rod of the double-rod piston cylinder 112. The lifting plate 4 drives the piston rod of the double-rod piston cylinder 112 to move downward, compressing the return spring 116, which pushes the air in the double-rod piston cylinder 112 into the air guide pipe 114. The air in the air guide pipe 114 is discharged into the diversion pipe 115, and the air in the diversion pipe 115 is discharged into the air cushion 111. As the air is discharged, the air cushion 111 expands and contacts the inner wall of the LED lamp cover, further fixing the LED lamp cover. When the piston rod of the double-rod piston cylinder 112 moves downward to its maximum stroke, the piston rod of the double-rod piston cylinder 112 stops moving downward. At this time, the lifting plate 4 continues to move downward, driving the double-rod piston cylinder 112 to move downward. As the lifting plate 4 moves downward, the first spring 113 is compressed, and when the lifting plate 4 stops moving downward, it stops driving the double-rod piston cylinder 112 to move downward. When the electric screw 6 starts to reverse, it drives the lifting plate 4 to move upward. The upward movement of the lifting plate 4 does not limit the double-rod piston cylinder 112. Due to the action of the first spring 113, the double-rod piston cylinder 112 moves upward and resets. The lifting plate 4 continues to reset and disengages from the piston rod of the double-rod piston cylinder 112. Due to the action of the reset spring 116, the piston rod of the double-rod piston cylinder 112 moves upward and resets. This also draws the air in the air cushion 111 back into the double-rod piston cylinder 112 through the air guide pipe 114 and the diverter pipe 115. As the air is drawn away, the air cushion 111 continuously contracts and resets, loosening the LED lamp cover. In this way, the loosening of the LED lamp cover can be prevented from affecting the grinding of the grinding wheel 8, thereby improving the stability of the LED lamp cover.

[0040] When the lifting plate 4 moves downward, causing the cover 7 to move downward, the cover 7 moves downward, causing the disengagement rod 125 to move downward. The disengagement rod 125 moves downward, causing the limiting rod 124 to move downward. When the limiting rod 124 moves downward and contacts the locking block 122, the limiting rod 124 causes the locking blocks 122 on both sides to swing outward, compressing the second spring 123. Then, when the lifting plate 4 stops moving the cover 7 downward, the cover 7 stops moving the disengagement rod 125 downward, and the disengagement rod 125 stops moving the limiting rod 124 downward. At this time, the limiting rod 124 does not limit the locking block 122. Due to the action of the second spring 123, the locking blocks 122 on both sides move inward, limiting the limiting rod 124. The limiting rod 124 then limits the disengagement rod 125, and the disengagement rod 125... When the LED lampshade is polished, the lifting plate 4 moves upward, causing the cover 7 to move upward. Due to the limiting effect of the detachment rod 125 on the LED lampshade, the upward movement of the cover 7 compresses the third spring 126, and the cover 7 causes the polishing wheel 8 to disengage from the LED lampshade. When the third spring 126 is compressed to its limit, the cover 7 moves upward, causing the detachment rod 125 to move upward through the third spring 126. The upward movement of the detachment rod 125 causes the limiting rod 124 to move upward. Due to the action of the second spring 123, the upward movement of the limiting rod 124 causes the locking block 122 to swing outward. The limiting rod 124 disengages from the locking block 122, and the limiting rod 124 stops being limited. Due to the action of the third spring 126, the detachment rod 125 moves downward, causing the limiting rod 124 to move and reset. In this way, when the cover 7 moves the grinding wheel 8 upward to reset, it can prevent the grinding wheel 8 from moving the LED lamp cover upward and causing it to fall and be damaged, thus ensuring that the LED lamp cover can be smoothly separated from the grinding wheel 8.

[0041] Example 3

[0042] Based on Embodiments 1 and 2, it also includes a jet pipe 13 and a mounting bracket 14. Please refer to [link / reference]. Figure 10 As shown, the front and rear right sides of the shield 2 are equipped with fixing brackets 14 by welding. The inner ends of the front and rear fixing brackets 14 are fixed with air jet pipes 13. When air is discharged into the air jet pipes 13, the air jet pipes 13 can spray out air to remove the polishing fluid and debris remaining on the LED lamp cover.

[0043] It also includes filter plate 15, please refer to Figure 10 As shown, a filter plate 15 is fixedly connected to the lower inner side of the liquid storage tank 103 along the circumferential direction. The filter plate 15 can filter impurities in the grinding fluid.

[0044] After the LED lampshade is placed, connect the air pump to the air jet pipe 13. Once the surface of the LED lampshade is polished, the polishing wheel 8 disengages from the LED lampshade. Start the air pump to expel air into the air jet pipe 13, which then sprays out the air to remove any remaining polishing fluid and debris from the LED lampshade. After all the polishing fluid and debris have been removed, turn off the air pump, and air will stop flowing into the air jet pipe 13. This prevents residual polishing fluid and debris from affecting subsequent processing, ensuring the LED lampshade is clean and tidy after polishing.

[0045] When the storage tank 103 is opened, the polishing fluid inside flows downwards and is discharged. The filter plate 15 filters out debris from the polishing fluid, and the polishing fluid after the debris is removed continues to be discharged downwards. In this way, a large amount of debris mixed in with the polishing fluid can be prevented from affecting subsequent use, thereby ensuring the effectiveness of subsequent use of the polishing fluid.
