Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and in particular to a robotic arm-type stainless steel tableware polishing machine. Background Technology

[0002] Stainless steel tableware has become the mainstream choice for modern catering utensils due to its corrosion resistance, easy cleaning, beautiful appearance and durability. In its production process, polishing is a crucial surface treatment process, which aims to remove scratches, obtain ideal luster such as mirror or matte finish, and improve product quality and added value. With the development of industrial automation, robotic arm polishing machines have begun to be used. It utilizes the high flexibility of industrial robots (robotic arms) to grab and control tableware to move along a preset trajectory and contact the polishing wheel to complete the polishing operation.

[0003] However, when such equipment is polishing, the polishing fluid (a liquid used for cooling and lubrication) is usually sprayed continuously. But tableware is usually small in size. This continuous spraying method results in a large amount of polishing fluid failing to act on the effective polishing area, causing waste of resources and increased costs. At the same time, since the polishing point changes in real time, the sprayed polishing fluid cannot ensure that the liquid accurately covers the current polishing position, which may affect the local polishing quality. Therefore, this application proposes a robotic arm type stainless steel tableware polishing machine. Summary of the Invention

[0004] The purpose of this invention is to address the problems of serious waste of polishing liquid and difficulty in accurate coverage in the prior art, and to propose a robotic arm-type stainless steel tableware polishing machine.

[0005] The technical solution of this invention: A robotic arm-type stainless steel tableware polishing machine includes a polishing table and two sets of side tables. An industrial robot for gripping and moving tableware is mounted on the top of each side table, along with a polishing wheel for polishing the tableware. A motor is installed inside the polishing table. A spur gear is driven to the output end of the motor. A second spur gear meshes with the outer side of the first spur gear. A connecting pipe is fixed between the second spur gear and the polishing wheel. The connecting pipe is rotatably connected to the polishing table. The machine also includes: A storage tank for storing polishing fluid has an inlet installed on the outside of the storage tank and a one-way valve installed inside the inlet. A transmission pipe is fixed to the bottom of the storage tank. A hose is fixed to the end of the transmission pipe near the storage tank and a nozzle is fixed to the end of the transmission pipe away from the hose. The nozzle is rotatably connected to the inside of the polishing wheel. The device includes a clamping block for squeezing and blocking the channel inside the hose, and a clamping plate fixed to the top of the side platform. The top of the side platform is provided with an intermittent control mechanism, which includes a moving component and a resetting component. The moving component is used to control the clamping block to move away from the hose, and the resetting component is used to control the moving component to reset, so that the clamping block squeezes the hose again. The transmission adjustment mechanism is used to realize the linkage between the moving component and the locking block, and to adjust the position of the locking block squeezing the hose; The pressurization mechanism, connected to the moving component, is used to intermittently increase the internal pressure of the reservoir, allowing the polishing fluid to enter the nozzle.

[0006] Optionally, the moving component includes a second motor, a third spur gear, a rack, a support plate, a guide groove, and an arc groove. The second motor is mounted on the top of the side platform. The third spur gear is connected to the outer side of the output end of the second motor. The rack meshes with the third spur gear and is connected to a transmission adjustment mechanism. The support plate is fixed to the bottom end of the rack. The guide groove is opened at the top of the side platform, and the support plate is slidably connected inside the guide groove. The arc groove is opened on the outer side of the third spur gear.

[0007] Optionally, the reset assembly includes a fixing plate and a spring, the fixing plate being fixedly connected to the top of the side platform, and the spring being fixedly connected between the fixing plate and the support plate.

[0008] Optionally, the transmission adjustment mechanism includes a connecting plate, an adjustment groove, two sets of side plates, and a screw. The connecting plate is fixedly connected to one end of the rack near the flexible hose. The adjustment groove is opened at one end of the connecting plate near the flexible hose. The locking block is slidably connected inside the adjustment groove. The two sets of side plates are respectively fixedly connected to the top and bottom ends of the connecting plate. The screw is threadedly connected to the inside of the locking block. Both ends of the screw are rotatably connected to the side plates, and the bottom end of the screw penetrates through the side plates.

[0009] Optionally, a circular plate is fixed to the bottom end of the screw, and multiple sets of protruding rods are fixed to the outer side of the circular plate.

[0010] Optionally, the cross-section of the adjustment groove is T-shaped.

[0011] Optionally, the pressurizing mechanism includes a turntable, a side rod, a connecting rod, a piston rod, a piston plate, two sets of sliders, two sets of slide grooves, and a second one-way valve. The turntable is drivenly connected to the output end of the second motor. The side rod is fixedly connected to the end of the turntable away from the second motor. The connecting rod is rotatably connected to the outer side of the side rod. The end of the connecting rod away from the side rod is rotatably connected to the outer side of the piston rod. The end of the piston rod away from the connecting rod is fixedly connected to the piston plate. The piston plate is slidably connected to the inside of the storage tank. Both sets of sliders are fixedly connected to the outer side of the piston plate. Both sets of slide grooves are formed on the inner wall of the storage tank. The sliders are slidably connected to the inside of the slide grooves. The second one-way valve is installed inside the storage tank.

[0012] Optionally, the contact surface between the piston plate and the liquid storage tank is made of rubber, and the piston plate is adapted to the internal size of the liquid storage tank.

[0013] Optionally, a liquid level sensor is installed on the outside of the liquid storage tank, the output of the liquid level sensor is connected to a controller, and the output of the controller is connected to an alarm.

[0014] Optionally, a fixing frame is fixed to the inner wall of the liquid storage tank, a second spring is fixed to the bottom end of the fixing frame, and a metal ball is fixed to the bottom end of the second spring.

[0015] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention achieves intermittent and precise quantitative supply of polishing fluid by driving the card block to periodically open and close the hose through an intermittent control mechanism, avoiding the waste caused by the continuous flow of a large amount of polishing fluid. The pressurization mechanism simultaneously increases the internal pressure of the storage tank when the valve is opened, ensuring that the liquid can be sprayed stably and quickly to the polishing point. The two work together to significantly save polishing fluid while improving the timeliness and reliability of cooling and lubrication, thereby ensuring the stability of polishing quality.

[0016] Furthermore, through the structural design of springs and metal balls, a passive disturbance device consisting of a fixed frame, springs, and metal balls is installed inside the liquid storage tank. This device can utilize the self-power of the liquid flow to continuously and gently agitate the polishing liquid inside the tank. This structure can effectively prevent abrasive particles in the polishing liquid from settling or locally solidifying, thereby ensuring that the composition of the polishing liquid is always uniform and stable, and guaranteeing the consistency of the spraying process and the stability of the polishing quality.

[0019] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the present invention proposes a robotic arm-type stainless steel tableware polishing machine, comprising a polishing table 1 and two sets of side tables 2. The polishing table 1 and the two sets of side tables 2 respectively support their top components. An industrial robot 3 for gripping and moving tableware and a polishing wheel 5 for polishing the tableware are mounted on the top of the side tables 2. During polishing, the industrial robot 3 first grips the tableware to be processed and places the area to be polished onto the surface of the polishing wheel 5. A motor 6 is installed inside the polishing table 1. The motor 6 is then started. The output end is connected to a spur gear 7. When the motor 6 runs, it drives the spur gear 7 to rotate at high speed. A spur gear 8 meshes with the outer side of the spur gear 7. The rotation of the spur gear 7 drives the rotation of the spur gear 8. A connecting pipe 9 is fixed between the spur gear 8 and the polishing wheel 5. The connecting pipe 9 is rotatably connected to the polishing table 1. The rotation of the spur gear 8 will eventually drive the polishing wheel 5 to rotate, thereby polishing the tableware. It should be noted that the industrial robot 3, the motor 6, and the polishing wheel 5 are all existing technologies and are mature. They will not be elaborated on in this embodiment.

[0023] As one implementation method, such as Figure 4 and Figure 5 As shown, the polishing machine also includes a storage tank 10 for storing polishing fluid. An inlet 11 is installed on the outside of the storage tank 10, through which polishing fluid can be added to the inside of the storage tank 10. The height of the polishing fluid inside the storage tank 10 will not exceed the height of the inlet 11. In this embodiment, the polishing fluid refers to a liquid used for cooling and lubrication. A one-way valve is installed inside the inlet 11. As prior art, the one-way valve ensures that liquid or gas can only enter the inside of the storage tank 10 through the inlet 11 and cannot be discharged through it. The storage tank 10... A transmission pipe 12 is fixedly connected to the bottom end of the device. A hose 13 is fixedly connected to one end of the transmission pipe 12 near the liquid storage tank 10, and a nozzle 14 is fixedly connected to the other end of the transmission pipe 12 away from the hose 13. The polishing liquid inside the liquid storage tank 10 can enter the interior of the nozzle 14 through the transmission pipe 12 and the hose 13, and be sprayed onto the surface of the polishing wheel 5 through the nozzle 14, so that the polishing liquid can be accurately applied to the effective polishing area, avoiding waste of resources. The nozzle 14 is rotatably connected to the interior of the polishing wheel 5. This connection method can ensure that the rotation of the polishing wheel 5 will not interfere with the nozzle 14, so that the nozzle 14 is always in a stationary state.

[0024] Furthermore, such as Figure 4 , Figure 6 and Figure 7As shown, the polishing machine also includes a clamping block 15 for squeezing and blocking the channel inside the hose 13, a transmission adjustment mechanism, and a clamping plate 41 fixed to the top of the side platform 2. In the first state, the clamping block 15, together with the clamping plate 41, squeezes the hose 13, causing the hose 13 to deform under force. The liquid channel inside the hose 13 will then be reduced. At this time, the liquid inside the storage tank 10 will encounter resistance when passing through the hose 13, thereby slowing down and reducing the flow into the transmission pipe 12. An intermittent control mechanism is provided at the top of the side platform 2. The intermittent control mechanism includes a moving component and a resetting component. The moving component is used to control the clamping block 15 away from the hose 13, and the transmission adjustment mechanism is used to realize the linkage between the moving component and the clamping block 15 and adjust the position of the clamping block 15 squeezing the hose 13. When a large amount of polishing liquid needs to be sprayed, the moving component can control the operation of the transmission adjustment mechanism. The transmission adjustment mechanism will then drive the clamping block 15 to move away from the clamping plate 41, and then the clamping block 15 will release the squeezing of the hose 13, and the liquid inside the storage tank 10 will then flow away from the hose 13. The liquid smoothly enters the interior of the transmission pipe 12, thereby increasing the liquid source for the nozzle 14. As the moving component continues to operate, after controlling the transmission adjustment mechanism for a certain distance, the moving component will release the control of the transmission adjustment mechanism. The reset component is used to control the moving component to reset, so that the locking block 15 squeezes the hose 13 again. At this time, the reset component will drive the transmission adjustment mechanism to reset, and the reset of the transmission adjustment mechanism will control the locking block 15 to squeeze the hose 13 again, so that the liquid is blocked again when passing through the internal channel of the hose 13, thereby slowing down and reducing the liquid flow into the transmission pipe 12. Then, by continuously repeating the above actions, the locking block 15 can be intermittently disengaged from the hose 13, and the flow rate of liquid entering the nozzle 14 can be intermittently controlled. This effectively prevents the waste of resources caused by the continuous flow of a large amount of liquid. In addition, the height of the locking block 15 can be controlled by the transmission adjustment mechanism, and the squeezing position of the locking block 15 on the hose 13 can be changed periodically, avoiding the situation where the fixed area of ​​the hose 13 is squeezed for a long time, causing serious damage to that area, and improving the service life of the hose 13.

[0025] Furthermore, such as Figure 4 and Figure 8 As shown, the polishing machine also includes a pressurizing mechanism connected to the moving component. The pressurizing mechanism is used to intermittently increase the internal pressure of the liquid storage tank 10, allowing the polishing liquid to enter the nozzle 14. When the moving component drives the locking block 15 to disengage from the hose 13 via the transmission adjustment mechanism, the moving component will synchronously drive the pressurizing mechanism to operate. At this time, the pressurizing mechanism will increase the internal air pressure of the liquid storage tank 10, allowing the liquid inside the liquid storage tank 10 to enter the nozzle 14 faster and more stably. When the reset component drives the transmission adjustment mechanism to reset, the moving component will drive the pressurizing mechanism to reset, releasing the pressurization of the liquid storage tank 10. Thus, when the locking block 15 disengages from the hose 13 again, the pressurizing mechanism will continue to increase the pressure inside the liquid storage tank 10.

[0026] As one implementation method, such as Figure 6 , Figure 7 and Figure 8 As shown, the moving assembly includes a second motor 20, a third spur gear 21, a rack 22, a support plate 23, a guide groove 24, and an arc groove 25. The moving assembly is described in detail below: The second motor 20 is mounted on the top of the side platform 2. The third spur gear 21 is connected to the outer side of the output end of the second motor 20. When the second motor 20 is running, its output end drives the third spur gear 21 to rotate. The rack 22 meshes with the third spur gear 21, and the rotation of the third spur gear 21 will drive the rack 22 to move away from the hose 13. The rack 22 is connected to the transmission adjustment mechanism, and the movement of the rack 22 will, through the transmission adjustment mechanism, drive the locking block 15 away from the hose 13, thereby releasing the compression on the hose 13 and allowing the liquid inside the storage tank 10 to pass smoothly through the hose 13. The support plate 23 is fixed to the bottom end of the rack 22, and the guide groove 24 is formed in... At the top of the side platform 2, the support plate 23 is slidably connected to the inside of the guide groove 24. When the rack 22 moves, the rack 22 will drive the support plate 23 to move stably inside the guide groove 24. It should be noted that the cross-section of the guide groove 24 is T-shaped, so when the support plate 23 is inside the guide groove 24, it will not wobble during movement. The arc groove 25 is opened on the outside of the spur gear 3 21. As the spur gear 3 21 continues to rotate, when the arc groove 25 reaches above the rack 22, the spur gear 3 21 disengages from the rack 22. At this time, the spur gear 3 21 can no longer drive the rack 22 to move, thus stopping the movement of the locking block 15.

[0027] Furthermore, such as Figure 6 As shown, the reset assembly includes a fixing plate 26 and a spring 27. The reset assembly is described in detail below: The fixing plate 26 is fixed to the top of the side platform 2, and the spring 27 is fixed between the fixing plate 26 and the support plate 23. When the support plate 23 moves away from the hose 13, the support plate 23 will also cooperate with the fixing plate 26 to compress the spring 27, causing the spring 27 to deform under force and generate elastic potential energy. When the arc groove 25 reaches the top of the rack 22, the spur gear 21 makes control contact with the rack 22, that is, the compression of the spring 27 by the support plate 23 ends, and the spring 27 will release its elastic potential energy. Yes, the support plate 23 is pushed to reset, and the reset of the support plate 23 will drive the rack 22 to reset. Finally, the reset of the rack 22 will drive the locking block 15 to squeeze the hose 13 again through the transmission adjustment mechanism, thus obstructing the liquid from passing through the internal channel of the hose 13. As the motor 20 continues to run, the spur gear 21 will mesh with the rack 22 again, thereby repeating the above action, so that the locking block 15 intermittently disengages from squeezing the hose 13, ensuring that the liquid inside the storage tank 10 is intermittently and smoothly sprayed onto the polishing area.

[0028] Furthermore, such as Figure 6 and Figure 7 As shown, the transmission adjustment mechanism includes a connecting plate 28, an adjustment groove 29, two sets of side plates 30, and a screw 31. The transmission adjustment mechanism is described in detail below: The connecting plate 28 is fixedly connected to the end of the rack 22 near the hose 13. When the rack 22 moves, it will drive the connecting plate 28 to move. The adjusting groove 29 is opened at the end of the connecting plate 28 near the hose 13. The locking block 15 is slidably connected to the inside of the adjusting groove 29. The two sets of side plates 30 are respectively fixed to the top and bottom ends of the connecting plate 28. When the connecting plate 28 moves, it will drive the two sets of side plates 30 to move. The screw 31 is threadedly connected to the inside of the locking block 15. The two ends of the screw 31 are respectively connected to... The side plate 30 is rotatably connected, and the bottom end of the screw 31 passes through the side plate 30. When the side plate 30 moves, it will drive the screw 31 to move. When the screw 31 moves, it will drive the locking block 15 to move closer to or further away from the hose 13. When the screw 31 is rotated in different directions, the cross section of the adjusting groove 29 is T-shaped. The screw 31 can cooperate with the adjusting groove 29 to limit the locking block 15, drive the locking block 15 to move upward or downward, thereby adjusting the compression height of the locking block 15 on the hose 13.

[0029] Among them, such as Figure 7 As shown, a circular plate 32 is fixedly connected to the bottom end of the screw 31. Multiple sets of protruding rods are fixedly connected to the outer side of the circular plate 32. When the screw 31 is rotated, the circular plate 32 can be driven to rotate by the multiple sets of protruding rods, and the rotation of the circular plate 32 drives the screw 31 to rotate. The design of multiple sets of protruding rods and circular plate 32 makes it easier to rotate the screw 31. The design of the protruding rods and circular plate 32 is more in line with human mechanics, allowing the operator to better control the force when rotating the screw 31.

[0030] As one implementation method, such as Figure 5 , Figure 8 and Figure 9 As shown, the pressurizing mechanism includes a turntable 33, a side rod 34, a connecting rod 35, a piston rod 36, a piston plate 16, two sets of sliders 17, two sets of slide grooves 18, and a one-way valve 19. The pressurizing mechanism is described in detail below: The turntable 33 is connected to the output end of the second motor 20. During operation, the second motor 20 also drives the turntable 33 to rotate. The side rod 34 is fixed to the end of the turntable 33 facing away from the second motor 20. Initially, when the clamping block 15 squeezes the hose 13, the side rod 34 is above the turntable 33. The connecting rod 35 is rotatably connected to the outer side of the side rod 34. As the turntable 33 rotates, it gradually moves the side rod 34 below it. During this movement, the side rod 34 pulls the connecting rod 35, causing it to swing. The end of the piston rod 36 furthest from the side rod 34 is rotatably connected to the outer side of the piston rod 36. The swinging of the connecting rod 35 pulls the piston plate 16 via the piston rod 36. The piston plate 16 is fixedly connected to the end of the piston rod 36 furthest from the connecting rod 35. The piston plate 16 is slidably connected to the inside of the liquid storage tank 10. Both sets of sliders 17 are fixedly connected to the outer side of the piston plate 16. Both sets of sliding grooves 18 are formed on the inner wall of the liquid storage tank 10. The sliders 17 are slidably connected to the inside of the sliding grooves 18. The piston plate 16 then drives the sliders 17 to move downwards along the inside of the sliding grooves 18. The downward movement of the stopper plate 16 compresses the air inside the liquid storage tank 10, increasing the internal pressure and allowing the liquid inside the tank 10 to be transported to the inside of the transmission pipe 12 more quickly and stably. The contact surface between the piston plate 16 and the liquid storage tank 10 is made of rubber, and the piston plate 16 is adapted to the internal size of the liquid storage tank 10. The rubber material increases the sealing between the piston plate 16 and the inner wall of the liquid storage tank 10. When the clamping block 15 compresses the hose 13 again, it indicates that the side rod 34 is once again above the turntable 33. The turntable 33 then drives the side rod 34 to reset. During the process, the turntable 33 will push the connecting rod 35 to swing back and reset. The reverse swing of the connecting rod 35 will pull the piston plate 16 upward and reset through the piston rod 36. The one-way valve 19 is installed inside the liquid storage tank 10. The one-way valve 19 can draw outside air into the liquid storage tank 10 when the piston plate 16 moves upward, in preparation for the next downward movement of the piston plate 16 to compress air. It should be noted that the one-way valve 19, as an existing mature technology, can only allow air to enter the liquid storage tank 10, but cannot discharge the air inside the liquid storage tank 10.

[0031] Furthermore, such as Figure 8 and Figure 9As shown, a liquid level sensor 37 is installed on the outside of the storage tank 10. The output end of the liquid level sensor 37 is connected to a controller. When the liquid level sensor 37 detects that the polishing liquid inside the storage tank 10 is insufficient, it will transmit a signal to the controller. The output end of the controller is connected to an alarm. After receiving the signal, the controller will drive the alarm to run. The alarm will then sound, thereby reminding the staff to add polishing liquid to the inside of the storage tank 10. It should be noted that the liquid level sensor 37, the controller, and the alarm are all existing technologies and are mature. They will not be elaborated on in this embodiment.

[0032] Furthermore, such as Figure 9 As shown, a fixing frame 38 is fixed to the inner wall of the liquid storage tank 10. A second spring 39 is fixed to the bottom end of the fixing frame 38. The fixing frame 38 supports the second spring 39, allowing the second spring 39 to suspend inside the liquid storage tank 10. A metal ball 40 is fixed to the bottom end of the second spring 39, and the second spring 39 supports the metal ball 40. When the liquid flows inside the liquid storage tank 10, the liquid will cause the metal ball 40 to shake. The shaking of the metal ball 40 and the elastic potential energy generated or released by the deformation of the second spring 39 will disturb the liquid inside the liquid storage tank 10, thereby alleviating the situation of liquid solidification or particle settling to the bottom.

[0033] In this embodiment, firstly, the industrial robot 3 grasps the tableware to be processed and places the area to be polished onto the surface of the polishing wheel 5. Then, motor 6 is started, and the output of motor 6 drives spur gear 7 to rotate at high speed. Spur gear 7 meshes with spur gear 8 and drives the polishing wheel 5 to rotate at high speed through the connecting pipe 9, thus starting the polishing operation. At the same time, motor 20 in the intermittent control mechanism is started, and its output drives spur gear 21 to rotate. Spur gear 21 drives the rack 22 meshing with it to move. The rack 22 drives the locking block 15 to move away from the locking plate 41 through the connecting plate 28 in the transmission adjustment mechanism, thereby releasing the squeezing of the hose 13 by the locking block 15, allowing the contents of the hose 13 to move freely. With the channel fully open, the polishing liquid in the storage tank 10 flows into the nozzle 14 through the transmission pipe 12 and hose 13, and is sprayed onto the surface of the polishing wheel 5 by the nozzle 14. During this process, the support plate 23 at the bottom of the rack 22 slides stably along the guide groove 24, compressing the spring 27 between the fixing plate 26 and the support plate 23. At the same time, the output end of the motor 20 drives the turntable 33 to rotate. The side rod 34 on the turntable 33 pulls the piston rod 36 and piston plate 16 downward through the connecting rod 35. The piston plate 16 drives the slider 17 to slide along the slide groove 18 and compress the air inside the storage tank 10. The sealing effect of the one-way valve 19 increases the air pressure inside the storage tank 10, allowing the polishing liquid to flow more quickly and stably. Nozzle 14; When spur gear 3 21 rotates until the arc groove 25 aligns with rack 22, spur gear 3 21 disengages from rack 22. Spring 1 27 releases its elastic potential energy, pushing support plate 23 and rack 22 to move in the opposite direction and reset. Rack 22, through connecting plate 28, drives block 15 to engage with block 41 again to squeeze hose 13, obstructing the liquid as it passes through the internal channel of hose 13. Simultaneously, turntable 33 continues to rotate, resetting side rod 34. Through connecting rod 35, piston rod 36 and piston plate 16 are pushed upwards, drawing air from the outside into storage tank 10 via check valve 2 19, preparing for the next pressurization. Thus, as motor 2 20 continues to run, block 15 intermittently disengages from hose 13. The polishing fluid is sprayed intermittently in large quantities. By rotating the multiple sets of protruding rods on the circular plate 32 at the bottom of the screw 31, the screw 31 can be driven to rotate. The screw 31, in conjunction with the T-shaped adjustment groove 29, drives the locking block 15 to move up and down along the adjustment groove 29, thereby periodically changing the squeezing position of the locking block 15 on the hose 13, avoiding damage to the hose 13 due to prolonged pressure in a single area. In addition, the liquid level sensor 37 on the outside of the liquid tank 10 monitors the polishing fluid level in real time. When the liquid level is insufficient, the controller drives the alarm to sound to remind the user to add more. At the same time, the fixing frame 38, spring 2 39 and metal ball 40 inside the liquid tank 10 shake when the liquid flows, disturbing the liquid to prevent solidification or particles from settling to the bottom.
