Description

Technical Field

[0001] The present invention relates to the field of manufacturing of automated instruments and meters, and specifically to an outer circle polishing device for circular wafers. Background Art

[0002] Automated instruments and meters are devices used for measuring, controlling, recording, and displaying physical quantities (such as temperature, pressure, flow rate, etc.). By integrating with a computer system, they achieve automatic control of the production process. The core of these devices is sensors and actuators, which form the "perception - decision - action" closed loop of the automated system.

[0003] In the field of manufacturing of automated instruments and meters, the processing and manufacturing of circular wafers is an important process. The circular wafers in automated instruments and meters are usually referred to as pressure gauge bases or connection rings. Its main function is to fix the pressure gauge and ensure its stability during operation. The polishing of the edge of the circular wafer is an important link in its processing. Therefore, an edge polishing device is usually used for polishing operations. Generally, the edge polishing device uses a mixture of a brush and abrasive liquid to rotate at high speed, and then forms a polishing effect on the edge of the wafer.

[0004] In traditional outer circle polishing devices for circular wafers, since both the brush and the circular wafer are placed vertically, in this case, the yaw when the brush rolls is likely to affect the polishing of the edge of the circular wafer, resulting in differences in the polished thickness of the edges of the circular wafers stacked on top of each other, causing different processing effects for the circular wafers stacked on top of each other, thus leading to poor polishing accuracy of the circular wafers, which is not conducive to actual use. Moreover, the loading and unloading operations of the circular wafers in traditional outer circle polishing devices for circular wafers are relatively cumbersome, making it inconvenient for workers to fix the center rod on the device to polish the circular wafers sleeved on it, or to conveniently disassemble the center rod from the device to take out the polished circular wafers sleeved on it from the inside of the device, resulting in the inability of workers to conveniently complete the loading and unloading operations of the circular wafers, thereby reducing the polishing efficiency of the circular wafers to a certain extent and having poor practicability. Summary of the Invention

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0024] Next, according to the overall structure of the present invention, its embodiments will be described.

[0025] A polishing device for the outer circle of a ring plate, as Figures 1-7 shown, includes a frame 1. Universal wheels are connected to the bottom of the frame 1 near the four corners. A chassis 5 is connected to the top of the frame 1. A support seat 25 is connected to the center of one side of the inner wall of the bottom of the chassis 5. The centers of the top inner walls on both sides of the support seat 25 are both movably connected with second clamping seats 23. Connecting grooves are opened at the centers of one side of the inner cavities of the two second clamping seats 23. Shafts are movably connected to the centers of the inner walls on both sides of the two connecting grooves. And first chucks 26 are connected to both of the shafts. Two fixing screw holes are opened in one side of the inner cavities of the two first chucks 26 and the two second clamping seats 23. A plurality of ring plate bodies 24 are arranged on one side of the two second clamping seats 23. And a central rod is movably connected to the common inner cavity of the plurality of ring plate bodies 24. End caps are sleeved on both ends of the central rod. A fixed seat 14 is connected to the center of the other side of the inner wall of the bottom of the chassis 5. Circular holes are opened at the centers of the top inner cavities of the fixed seat 14. And a connecting arm central axis 31 is movably connected to the common inner cavity of the two circular holes. One end of the connecting arm central axis 31 penetrates through the inner cavity of the adjacent circular hole. And a brush roller connecting arm 17 is connected to the connecting arm central axis 31 near one end. The centers of the top inner walls on both sides of the brush roller connecting arm 17 are both movably connected with first clamping seats 22. And a brush roller body 21 is arranged in the common inner cavity of the two first clamping seats 22. Fixing grooves are opened at the centers of one side of the inner cavities of the two first clamping seats 22. Connecting rods are movably connected to the centers of the inner walls on both sides of the two fixing grooves. And second chucks 28 are connected to both of the connecting rods. Two connecting screw holes are opened in one side of the inner cavities of the two second chucks 28 and the two first clamping seats 22.

[0026] When the staff needs to use this circular wafer polishing equipment to polish the circular wafers, at this time, the staff moves this circular wafer polishing equipment to the working area through the four universal wheels at the bottom of the frame 1. Then, the staff pours an appropriate amount of abrasive liquid into the liquid storage tank 8. Next, the staff flips up the door panel 6 to open the chassis 5. When the staff opens the chassis 5, at this time, the staff flips two clamping heads one 26 to open two clamping seats one 22. When the staff opens two clamping seats one 22, at this time, the staff places both ends of the brush roller body 21 inside the brush roller body 21. When the staff places the brush roller body 21 inside two clamping seats one 22, at this time, the staff flips two clamping heads one 26 again so that two clamping heads one 26 come into contact with two brush roller bodies 21 again. When two clamping heads one 26 come into contact with two brush roller bodies 21 again, at this time, the staff screws the bolts into the adjacent two connecting screw holes in turn, so as to firmly fix the brush roller body 21 between two clamping seats one 22 to polish the circular wafers. Similarly, when the staff needs to replace the brush roller body 21, at this time, the staff screws the bolts out of the adjacent two connecting screw holes in turn. Then, the staff flips two clamping heads one 26 to open two clamping seats one 22, so that the staff can take out the brush roller body 21 from inside two clamping seats one 22 for replacement. When the staff places the new brush roller body 21 inside two clamping seats one 22 again, at this time, the staff repeats the above operation to fix the new brush roller body 21 between two clamping seats one 22 for use. When the staff fixes the brush roller body 21 between two clamping seats one 22, at this time, the staff sleeves the circular wafer body 24 on the central rod in turn. After a certain number of circular wafer bodies 24 are sleeved on the central rod, then two end caps are sleeved on both ends of the central rod, so that two end caps can press the circular wafer bodies 24 stacked on the central rod one by one. When the staff uses two end caps to press a number of circular wafer bodies 24 sleeved on the central rod, then the staff flips two clamping heads two 28 to open two clamping seats two 23. When the staff opens two clamping seats two 23, at this time, the staff places both sides of the end cap inside two clamping seats two 23 and makes both sides of the end cap in close contact with one side of two clamping seats two 23. When the staff places two end caps inside two clamping seats two 23, at this time, the staff flips two clamping heads two 28 again so that two clamping heads two 28 come into contact with two clamping seats two 23 again. When two clamping heads two 28 come into contact with two clamping seats two 23 again, at this time, the staff screws the bolts into the adjacent two fixing screw holes in turn, so as to firmly fix a number of circular wafer bodies 24 sleeved on the central rod between two clamping seats two 23 for polishing operation. Similarly, when the edge polishing operation of a number of circular wafer bodies 24 fixed between two clamping seats two 23 is completed, at this time, the staff screws the bolts out of the adjacent two fixing screw holes in turn,Furthermore, the two clamping seats II 23 can be opened again, so that the two end caps sleeved on the central rod can be released from the restriction, which is beneficial for the staff to take out several ring plate bodies 24 polished and sleeved on the central rod from the inside of the ring plate polishing device, thus achieving the purpose of conveniently loading and unloading the ring plate bodies 24. It enables the staff to conveniently fix several ring plate bodies 24 sleeved on the central rod between the two clamping seats II 23 for polishing operations. Similarly, it also enables the staff to take out several polished ring plate bodies 24 sleeved on the central rod from the inside of the ring plate polishing device, thereby improving the polishing efficiency of the ring plates to a certain extent, with strong practicability and convenience for the staff to operate. When the staff firmly fixes several ring plate bodies 24 sleeved on the central rod between the two clamping seats II 23, at this time, the staff starts the electric telescopic rod 11 through an external power supply, so that the electric telescopic rod 11 can drive the brush roller body 21 to turn downward and be in close contact with several ring plate bodies 24, so as to facilitate the brush roller body 21 placed horizontally to polish several ring plate bodies 24 placed horizontally. This is to avoid the form of the brush roller body 21 and the ring plate body 24 being placed vertically, which may cause the yaw when the brush roller body 21 rolls to easily affect the polishing of the edge of the ring plate, resulting in different processing effects of the ring plates stacked up and down. After the brush roller body 21 is in close contact with several ring plate bodies 24, at this time, the staff starts the water pump 7 through an external power supply, so that the water pump 7 can pump out the sand liquid in the liquid storage tank 8 and spray it on the brush roller body 21. Then the staff starts the driving motor I 2 and the driving motor II 9 through an external power supply, so that the driving motor I 2 can drive several ring plate bodies 24 to rotate clockwise and the driving motor II 9 can drive the brush roller body 21 to rotate counterclockwise, thereby polishing the edges of several ring plate bodies 24. Repeating the above operations can polish more ring plate bodies 24.

[0027] As Figure 1 and Figure 2 shown, one side of the chassis 5 is provided with an opening, and one side of the chassis 5 is provided with a door panel 6 that matches the opening. One side of the door panel 6 is provided with several hinges, and the door panel 6 is movably connected to the chassis 5 through several hinges.

[0028] The staff flips the door panel 6 upward or downward, so that the staff can quickly open the chassis 5 for a series of operations or close the chassis 5 to protect the internal components.

[0029] As Figures 1-7As shown in the figure, a fixing frame 16 is connected to the center of one side of the frame 1, and an electric telescopic rod 11 is movably connected to the top of the fixing frame 16. A square groove is opened at the center of the top of one side of the chassis 5. One side of the electric telescopic rod 11 is movably connected in the square groove. One end of the electric telescopic rod 11 is movably connected to a hinge plate 18. One side of the hinge plate 18 is connected to a connecting plate 30. The two sides of the connecting plate 30 are respectively connected to the centers of the inner walls of the two sides of the brush roller connecting arm 17. Two liquid spraying pipes 20 are connected to both sides of the connecting plate 30. Two conduits 19 are connected to the centers of one side of the two liquid spraying pipes 20. A square opening is opened at the center of one side of the chassis 5. One end of several conduits 19 all penetrates through the inner cavity of the square opening and is connected to a water pump 7. The bottom of the water pump 7 is connected to a liquid storage tank 8. The input end of the water pump 7 extends to the inside of the liquid storage tank 8. The bottom of the liquid storage tank 8 is connected to one side of the bottom of the frame 1. One side of the top of the liquid storage tank 8 is connected to a bottom plate 4.

[0030] After the staff firmly fixes several ring plate bodies 24 sleeved on the central rod between the two clamping seats two 23, at this time, the staff starts the electric telescopic rod 11 through an external power supply. The electric telescopic rod 11 starts to extend out in the powered-on state, so that the electric telescopic rod 11 can drive the brush roller connecting arm 17 to turn downward. When the brush roller connecting arm 17 turns downward, it can drive the brush roller body 21 to turn downward. Furthermore, the brush roller body 21 can quickly come into close contact with several ring plate bodies 24 fixed between the two clamping seats two 23, so as to facilitate the polishing operation of the horizontally placed brush roller body 21 on the horizontally placed several ring plate bodies 24. In this way, it can be avoided that the brush roller body 21 and the ring plate body 24 are placed vertically, resulting in the yaw when the brush roller body 21 rolls easily affecting the polishing of the edge of the ring plate, causing the processing effects of the ring plates stacked up and down to be different. Thus, the polishing accuracy of the ring plate is improved to a certain extent, which is beneficial to actual use. When the brush roller body 21 is in close contact with several ring plate bodies 24, at this time, the staff starts the water pump 7 through an external power supply, so that the water pump 7 can introduce the sand liquid in the liquid storage tank 8 into the two liquid spraying pipes 20 through the four conduits 19 in the powered-on state, and then spray it on the brush roller body 21 through the two liquid spraying pipes 20. Furthermore, the brush roller body 21 can be mixed with the sand liquid to polish the edge of the ring plate body 24. At the same time, the sprayed sand liquid can flow back into the liquid storage tank 8 again through the two drain pipes, so as to recycle the sand liquid.

[0031] As Figures 4-6 shown, drain pipes are provided at the centers of one side of the liquid storage tank 8 and the bottom plate 4. Two water leakage holes are opened at one side of the bottom of the chassis 5. The side walls of the two drain pipes are respectively connected to the inner walls of the adjacent water leakage holes.

[0032] Through two drain pipes at the bottom of the chassis 5, the sprayed sand liquid can flow back into the liquid storage tank 8 through the two drain pipes again, thus achieving the purpose of recycling the sand liquid.

[0033] As Figures 1-5 shown, a drive shaft 29 is connected to the center of one side of the second clamping seat 23 on one side. Activity holes are provided at the center of the top side of the inner cavity of the support seat 25 and at the center of one side of the chassis 5. One end of the drive shaft 29 sequentially penetrates the inner cavities of the two activity holes and is connected to a first driven sprocket 12. A first bearing is sleeved on the center of the drive shaft 29, and the side walls of the first bearing are connected to the inner walls of the adjacent activity holes. A first drive sprocket 3 is provided at the bottom of the first driven sprocket 12. The first drive sprocket 3 and the first driven sprocket 12 are jointly engaged with a first chain, and the first drive sprocket 3 and the first driven sprocket 12 are connected by the first chain for transmission. A first drive motor 2 is provided on one side of the first drive sprocket 3. The bottom of the first drive motor 2 is connected to the bottom of one side of the frame 1, and one end of the power output shaft of the first drive motor 2 is connected to the center of one side of the first drive sprocket 3.

[0034] The staff starts the first drive motor 2 through an external power supply, so that the first drive motor 2 can drive the first drive sprocket 3 to rotate clockwise when powered on. When the first drive sprocket 3 rotates clockwise, it can drive the first driven sprocket 12 to rotate clockwise synchronously through the first chain. Furthermore, the first driven sprocket 12 can drive a plurality of ring plate bodies 24 fixed between the two second clamping seats 23 to rotate clockwise for edge polishing operations through the adjacent second clamping seats 23.

[0035] As Figures 2-5 shown, a rotation hole is provided at the bottom of one side of the chassis 5. One end of the central shaft 31 of the connecting arm penetrates the inner cavity of the rotation hole and is connected to a second driven sprocket 13. A second bearing is sleeved on the connecting arm central shaft 31 near one end, and the side walls of the second bearing are connected to the inner walls of the rotation hole. A second drive sprocket 10 is provided at the bottom of the second driven sprocket 13. The second drive sprocket 10 and the second driven sprocket 13 are jointly engaged with a third chain, and the second drive sprocket 10 and the second driven sprocket 13 are connected by the third chain for transmission. A second drive motor 9 is provided on one side of the second drive sprocket 10. The bottom of the second drive motor 9 is connected to the bottom of one side of the frame 1, and one end of the power output shaft of the second drive motor 9 is connected to the center of one side of the second drive sprocket 10.

[0036] The staff starts the driving motor 29 through an external power supply, so that the driving motor 29 can drive the driving sprocket 2 10 to rotate counterclockwise when powered on. When the driving sprocket 2 10 rotates counterclockwise, the driven sprocket 2 13 can be driven to rotate counterclockwise synchronously through the third chain. When the driven sprocket 2 13 rotates counterclockwise, the linkage sprocket 27 thereon can be driven to rotate counterclockwise through the connecting arm center shaft 31. When the linkage sprocket 27 on the connecting arm center shaft 31 rotates counterclockwise, the linkage sprocket 27 on one side can be driven to rotate counterclockwise synchronously through the second chain. Then, the linkage sprocket 27 on one side can be driven to rotate counterclockwise quickly through the adjacent card seat 1 22 to polish the edges of several circular ring sheet bodies 24 fixed between the two card seats 23.

[0037] like Figure 3 and Figure 4 As shown, a linkage sprocket 27 is connected to the center axis 31 of the connecting arm near one end, and a linkage sprocket 27 is also movably connected to the center of the top of one side of the brush roller connecting arm 17. A rotating shaft is connected to the center of one side of the linkage sprocket 27 at the top. An opening is provided at the center of the top of one side of the inner cavity of the brush roller connecting arm 17. One end of the rotating shaft passes through the inner cavity of the opening and is connected to the center of one side of the adjacent card seat 22. A transmission sprocket 15 is provided on one side of the two linkage sprockets 27, and one side of the transmission sprocket 15 is movably connected to the center of one side of the brush roller connecting arm 17. A second chain is engaged with the transmission sprocket 15 and the two linkage sprockets 27, and the transmission sprocket 15 and the two linkage sprockets 27 are connected by a second chain transmission.

[0038] When the central shaft 31 of the connecting arm drives the interlocking sprocket 27 thereon to rotate counterclockwise, the interlocking sprocket 27 on the central shaft 31 of the connecting arm can drive the interlocking sprocket 27 on one side to rotate counterclockwise synchronously through the second chain, so that the interlocking sprocket 27 on one side can quickly drive the brush roller body 21 to rotate counterclockwise through the adjacent card seat 1 22, which is beneficial for the brush roller body 21 to polish the edges of several circular ring sheet bodies 24 fixed between the two card seats 23. At the same time, when the second chain rotates counterclockwise, it can drive the transmission sprocket 15 to rotate counterclockwise synchronously, thereby limiting the position of the second chain and allowing the second chain to rotate stably counterclockwise.
