Description

Technical Field

[0001] This disclosure relates to the field of processing equipment, and more specifically, to a polishing device and polishing system. Background Technology

[0002] After the grinding manufacturing process is completed, the cutting tool needs to be polished to reduce the surface roughness of the tool, so as to obtain a bright and smooth surface, improve the surface stress state, and improve the tool's durability.

[0003] In related technologies, high-speed flowing abrasive particles are sprayed onto the surface of cutting tools for polishing. The specific process includes: pouring prepared abrasive into a sandblasting machine, fixing the workpiece at the spray nozzle of the sandblasting machine, starting the sandblasting machine, and spraying the abrasive from the nozzle onto the cutting tool for polishing. If these polishing processes are completed manually, the workload is large, the labor cost is high, resulting in limited production capacity and difficulty in achieving mass production. Summary of the Invention

[0004] The purpose of this disclosure is to provide a polishing device with a high degree of automation in the polishing process, which helps to reduce labor costs and increase production capacity to meet the needs of mass production.

[0005] Another object of this disclosure is to provide a polishing system to improve the stability and efficiency of the polishing process.

[0006] To solve the above-mentioned technical problems, the present disclosure adopts the following technical solution.

[0007] According to one aspect of this disclosure, a polishing machine is provided, comprising: a frame having an abrasive working chamber, a polishing chamber, a loading and unloading chamber, and a storage chamber communicating with the bottom of the abrasive working chamber; the polishing chamber and the abrasive working chamber are separated, and a spraying assembly is provided on the partition wall between them; the loading and unloading chamber has a loading area and a unloading area; a workpiece clamping device is installed in the polishing chamber, which is adapted to be displaced relative to the frame along a first direction and to drive the workpiece to be polished to rotate about its own axis; an abrasive conveying device is installed in the abrasive working chamber for lifting the abrasive in the storage chamber upward and centrifugally spraying it along the spraying assembly onto the workpiece to be polished on the workpiece clamping device; and a workpiece clamping device is installed in the loading and unloading chamber, which includes a clamping assembly; the clamping assembly is adapted to be displaced and rotated relative to the frame to drive the workpiece to be polished in the loading area to be loaded into the workpiece clamping device along the first direction consistent with its axial direction, polished, and then unloaded to the unloading area.

[0008] According to another aspect of this disclosure, a polishing system is provided, including the polishing apparatus, external input unit, sensing unit, and control unit as described in any of the above embodiments;

[0009] The sensing unit includes a first and a second sensing device respectively installed in the loading / unloading chamber and the polishing chamber; the first and second sensing devices are respectively used to detect the positions of the workpiece clamping device and the workpiece holding device and send first and second position signals;

[0010] The external input unit is mounted on the rack and includes a control panel and a start / stop button; the control panel is used to receive preset information and send preset signals; the start / stop button is used to provide external input and send start and stop signals.

[0011] The control unit is used to receive the start signal, stop signal, and first and second position signals, control the operation of the abrasive conveying device, workpiece clamping device, and workpiece holding device according to the start signal, stop signal, and preset signal, and determine whether each device has moved to the designated position according to the first and second position signals; when each device moves to the designated position, control each device to perform the preset action.

[0012] As can be seen from the above technical solutions, the embodiments disclosed herein have the following advantages and positive effects:

[0013] The workpiece loading and polishing process: The workpiece to be polished is picked up by the clamping component of the workpiece clamping device from the loading area, and the workpiece to be polished is loaded into the workpiece clamping device along the first direction consistent with its axis. The workpiece clamping device is displaced relative to the frame along the first direction and drives the workpiece to be polished to rotate around its own axis. The abrasive conveying device lifts the abrasive in the storage chamber upward and centrifugally sprays it along the spraying component onto the workpiece to be polished on the workpiece clamping device for polishing.

[0014] The unloading process after workpiece polishing: The workpiece after polishing is picked up by the clamping component of the workpiece clamping device and withdrawn from the workpiece clamping device in the first direction consistent with its axis. The clamping component drives the polished workpiece to move and rotate relative to the frame and unload it to the unloading area.

[0015] The polishing process for one workpiece is completed with each loading and unloading operation, resulting in a high degree of automation. Repeating these two processes sequentially enables batch production of multiple workpieces, improving production efficiency and expanding capacity. Furthermore, both processes require no manual intervention, reducing labor costs.

[0016] The workpiece clamping device secures the workpiece to be polished within the polishing chamber, preventing grinding debris from contaminating the workpieces in the loading and unloading chambers, the polished workpieces, and the abrasive in the abrasive chamber and storage chamber. It also prevents environmental contamination. The workpiece clamping device moves the workpiece along a first direction and allows it to rotate around its own axis, ensuring that all surfaces of the workpiece are polished by the abrasive. This also ensures consistent polishing time at different locations on the workpiece surface, improving polishing uniformity. Attached Figure Description

[0041] Typical embodiments embodying the features and advantages of this disclosure will be described in detail in the following description. It should be understood that this disclosure can have various variations in different embodiments without departing from the scope of this disclosure, and the descriptions and drawings therein are illustrative in nature and not intended to limit this disclosure.

[0042] Please see Figure 1 For ease of description, unless otherwise specified, the directions of front, back, left, right, up, and down in this article are represented as follows: X direction is left, opposite direction is right, Y direction is front, opposite direction is back, Z direction is up, and opposite direction is down. Specifically, the first direction is left-right, the second direction is front-back, and the third direction is up-down. The first and second directions are both on the horizontal plane, while the third direction is on the vertical plane.

[0043] Please refer to Figure 1 to... Figure 5 A polishing machine according to an embodiment of this disclosure mainly includes a frame 1, a workpiece clamping device 3, an abrasive conveying device 5, and a workpiece gripping device 4. The frame 1 contains an abrasive chamber 101, a polishing chamber 151, a loading / unloading chamber 102, and a storage chamber 13 communicating with the bottom of the abrasive chamber 101. The polishing chamber 151 is separated from the abrasive chamber 101, and a spraying assembly 6 is provided on the partition wall between them. The loading / unloading chamber 102 contains a loading area and a unloading area. The workpiece clamping device 3 is installed in the polishing chamber 151, and is adapted to move relative to the frame 1 in a first direction and drive the workpiece to be polished to rotate around its own axis. The abrasive conveying device 5 is installed in the abrasive chamber 101, and is used to lift the abrasive in the storage chamber 13 upwards and centrifugally spray it along the spraying assembly 6 onto the workpiece to be polished on the workpiece clamping device 3. The workpiece gripping device 4 is installed in the loading / unloading chamber 102, and includes a gripping assembly 41. The clamping assembly 41 is adapted to move and rotate relative to the frame 1 so as to drive the workpiece to be polished in the loading area to be loaded into the workpiece clamping device 3 in a first direction consistent with its axial direction, and then unloaded to the unloading area after polishing.

[0044] Please see Figures 1 to 5The frame 1 mainly includes a frame 11, a housing 12, a storage chamber 13, a filter screen 14, and a polishing chamber 15. The housing 12 is connected to the frame 11, and the interior of the housing 12 forms an installation space. The housing 12 serves as a protective shell, protecting the various components of the polishing machine installed within the installation space. The installation space includes an abrasive working chamber 101 located on the left and a loading / unloading chamber 102 and a control chamber 103 located on the right. The loading / unloading chamber 102 is located above the control chamber 103. The storage chamber 13 is located in the abrasive working chamber 101, with an opening at the top. The interior space of the storage chamber 13 is used to store abrasive. The filter screen 14 is located above the top opening at the rear end of the storage chamber 13. The filter screen 14 is used to filter the abrasive added to the storage chamber 13, preventing impurities from contaminating the abrasive and affecting the polishing effect. The polishing chamber 15 is located in the abrasive working chamber 101. The polishing chamber 15 has a polishing chamber 151 inside. The polishing chamber 15 is connected to the upper part of the front end of the storage chamber 13, and the bottom of the polishing chamber 151 is connected to the internal space of the storage chamber 13.

[0045] Please see Figure 6 and combined Figure 4 and Figure 5 The polishing equipment also includes a workpiece loading and unloading device 2, which is located in the loading and unloading chamber 102. The workpiece loading and unloading device 2 includes a loading tray 21 and a loading and unloading displacement component 22.

[0046] The loading tray 21 is used to place workpieces. The loading / unloading displacement component 22 drives the loading tray 21 to move relative to the frame 1 along a first direction, approaching or moving away from the workpiece clamping device 3. When the loading tray 21 moves to the left, it moves closer to the workpiece clamping device 3, shortening the displacement stroke, which facilitates the workpiece clamping device 4 to move the workpiece between the workpiece loading / unloading device 2 and the workpiece clamping device 3. When the loading tray 21 moves to the right, it moves away from the workpiece clamping device 3 and closer to the right side of the frame 1, making it convenient to pick up and put down the workpiece. The loading tray 21 has multiple placement positions for placing workpieces. In this embodiment, the workpiece is a rod-shaped tool, and the placement position is a cylindrical hole. A guide rail extending along the first direction is connected above the bottom surface of the loading / unloading chamber 102. The slider at the bottom of the loading tray 21 and the guide rail form a sliding fit to guide and limit the displacement of the loading tray 21, improving the displacement stability of the loading tray 21.

[0047] The loading tray 21 includes a loading tray 211, a unloading tray 212, and a connecting plate 23. The connecting plate 23 connects the loading tray 211 and the unloading tray 212. The loading / unloading displacement component 22 drives the connecting plate 23, simultaneously moving the loading tray 211 and the unloading tray 212. The loading tray 211 and the unloading tray 212 separate the workpieces to be polished and the polished workpieces, facilitating the loading and unloading of the entire tray. The area where the loading tray 211 is located is the loading area of ​​the loading / unloading chamber 102, and the area where the unloading tray 212 is located is the unloading area of ​​the loading / unloading chamber 102. The loading / unloading displacement component 22 is a cylinder.

[0048] Of course, in other embodiments, the workpieces to be polished can also be stacked in the loading area, and the polished workpieces can also be stacked in the unloading area.

[0049] Please see Figure 8 and Figure 9 and combined Figure 4 and Figure 5 The workpiece clamping device 3 is installed inside the polishing chamber 151. The workpiece clamping device 3 fixes the workpiece within the polishing chamber 151 for polishing, preventing grinding debris from overflowing and contaminating the workpiece to be polished in the loading / unloading chamber 102, the polished workpiece, and the abrasive in the abrasive working chamber 101 and the storage chamber 13. It also prevents pollution of the external environment. The workpiece clamping device 3 includes a clamping assembly 31, a clamping assembly rotating component 32, and a clamping assembly displacement component 33.

[0050] The clamping assembly 31 is used to clamp or release a workpiece. The clamping assembly 31 includes a chuck 311 and jaws. The chuck 311 has a receiving hole 3111 extending in a first direction for inserting a workpiece. The jaws are displaceably connected to the chuck 311 to adjust their length extending into the receiving hole 3111. After the workpiece is inserted into the receiving hole 3111, the jaws extend into the receiving hole 3111 by displacement, allowing the jaws to abut against the workpiece and clamp it within the receiving hole 3111. Conversely, the jaws shorten their extension into the receiving hole 3111 by displacement, allowing the jaws to separate from the workpiece and release it. Multiple jaws are provided and circumferentially spaced around the receiving hole 3111. By adjusting the multiple jaws, the workpiece can be positioned centrally within the receiving hole 3111.

[0051] The clamping assembly rotating component 32 drives the clamping assembly 31 to rotate the workpiece to be polished around its own axis, ensuring that the polished surface of the workpiece can be sprayed with abrasive and improving the polishing uniformity. It should be noted that the spray nozzle of the abrasive is fixed. The rotation of the workpiece helps to ensure that different positions on the workpiece surface are polished by the abrasive for a consistent time, thus improving the polishing uniformity.

[0052] The clamping assembly rotating component 32 and the clamping assembly 31 are also connected by a conveyor belt assembly. The belt drive can buffer and absorb vibration, reducing the impact of inertial impact force generated when the turntable 512 is eccentric on the device and improving transmission stability. In this embodiment, the clamping assembly rotating component 32 is a motor. The motor and the chuck 311 are connected by a conveyor belt assembly, and the belt drive transmits the torque of the motor to the chuck 311 to drive the chuck 311 to rotate.

[0053] The clamping assembly displacement member 33 drives the clamping assembly 31 to move the workpiece relative to the frame 1 back to its original position in the first direction. This not only further improves the polishing uniformity but also increases the coverage area of ​​the abrasive ejected from the nozzle, enabling the polishing of longer workpieces. In this embodiment, the clamping assembly rotation member 32 drives the clamping assembly 31 to rotate around the X-axis, and the clamping assembly displacement member 33 drives the clamping assembly 31 to move back to its original position in the left-right direction. The clamping assembly 31 moves to the left to approach the nozzle for polishing, and moves to the right to approach the workpiece loading / unloading device 2, facilitating the movement of the workpiece between the workpiece clamping device 3 and the workpiece loading / unloading device 2.

[0054] The clamping assembly displacement member 33 and the clamping assembly 31 are also connected by a conveyor belt assembly for transmission to improve transmission stability. In this embodiment, the clamping assembly rotating member 32 is a motor, the chuck 311 is rotatably mounted on the support plate 34, and a drive block is provided at the bottom of the support plate 34. The drive block is fixedly connected to the conveyor belt. The motor drives the pulley to rotate, and the pulley drives the conveyor belt wrapped around it to move, which in turn drives the support plate 34 to move through the drive block, thus transmitting the torque of the motor to the support plate 34 to drive the support plate 34 to move. The conveyor belt assembly is also covered with a dust cover 36 to prevent the grinding caused by polishing from affecting the transmission stability of the conveyor belt.

[0055] A guide rail extending in a first direction spans the polishing chamber 151. A slider is fixedly connected to the bottom of the support plate 34, and the slider is displaceably connected to the guide rail. The slider and the guide rail form a sliding fit to guide and limit the displacement of the support plate 34, improving the displacement stability of the support plate 34. A corrugated dust cover 35 is also provided over the slider and the guide rail to prevent the grinding generated during polishing from affecting the sliding fit between the slider and the guide rail.

[0056] Please return Figure 6 and Figure 7 and combined Figure 4 and Figure 5 The workpiece clamping device 4 is installed in the loading and unloading chamber 102. The workpiece clamping device 4 mainly includes a clamping assembly 41, a clamping assembly driving component 42, a clamping assembly displacement component 43, a clamping assembly rotating component 44, and a buffer component 48.

[0057] The clamping assembly 41 is used to clamp or release the workpiece. The clamping assembly 41 includes a first clamping block 411 and a second clamping block 412. When the first clamping block 411 and the second clamping block 412 are respectively moved to both sides of the workpiece, the first clamping block 411 and the second clamping block 412 move closer to each other to clamp the workpiece and move further away from each other to release the workpiece.

[0058] The clamping component drive 42 drives the first clamping block 411 and the second clamping block 412 to move closer or further apart to clamp or release the workpiece. In this embodiment, the clamping component drive 42 is a cylinder. The first clamping block 411 is fixed to the cylinder body, and the piston rod of the cylinder is connected to the second clamping block 412. When the piston rod of the cylinder shortens, the first clamping block 411 and the second clamping block 412 move closer together. When the piston rod of the cylinder extends, the first clamping block 411 and the second clamping block 412 move further apart. It can be understood that the principle of clamping or releasing the workpiece by the clamping component 31 and the clamping component 41 is to fix or de-fix the workpiece. Therefore, the structural designs of the clamping component 31 and the clamping component 41 can be interchanged in certain applicable scenarios.

[0059] In this embodiment, two sets of clamping components 41 and clamping component drivers 42 are provided. These are a first clamping component 413, a first clamping component driver 421, a second clamping component 414, and a second clamping component driver 422. The first clamping component 413 and the first clamping component driver 421 cooperate to clamp or release the workpiece to be polished during the workpiece loading and polishing process. The second clamping component 414 and the second clamping component driver 422 cooperate to clamp or release the polished workpiece during the workpiece unloading process after polishing. The loading and unloading clamping actions are performed by two clamping components 41 respectively, improving the stability of the operation.

[0060] Main references Figure 4 The clamping component displacement member 43 drives the clamping component 41 to move between the workpiece loading / unloading device 2 and the workpiece clamping device 3. Specifically, during the loading and polishing process, when the clamping component displacement member 43 synchronously moves the first clamping component 413 and the second clamping component 414 to the workpiece loading / unloading device 2, the first clamping component drive member 421 drives the first clamping component 413 to clamp the workpiece to be polished on the workpiece loading device. If the second clamping component 414 has a polished workpiece clamped on it, the second clamping component drive member 422 drives the second clamping component 414 to release the polished workpiece so that the polished workpiece can be placed on the workpiece loading / unloading device 2. If the second clamping component 414 does not have a polished workpiece clamped on it, the second clamping component drive member 422 does not perform any action.

[0061] The clamping component displacement member 43 drives the first clamping component 413 and the second clamping component 414 to move synchronously to the workpiece clamping device 3, and aligns the second clamping component 414 with the polished workpiece on the workpiece clamping device 3. The second clamping component drive member 422 drives the second clamping component 414 to clamp the polished workpiece on the workpiece clamping device 3. The workpiece clamping device 3 releases the polished workpiece, and at the same time, the clamping component displacement member 43 drives the second clamping component 414 to remove the polished workpiece from the workpiece clamping device 3, and aligns the workpiece to be polished on the first clamping component 413 with the workpiece clamping device 3. The workpiece clamping device 3 clamps the workpiece to be polished on the first clamping component 413, and at the same time, the first clamping component drive member 421 drives the first clamping component 413 to release the workpiece to be polished.

[0062] Understandably, during the initial startup of the polishing machine, no workpieces have been polished on the workpiece clamping device 3, therefore the second clamping assembly 414 does not clamp any polished workpieces. During subsequent operation, the polishing machine has already polished the workpieces, so the second clamping assembly 414 now clamps polished workpieces. Therefore, after the second clamping assembly 414 removes the polished workpiece from the workpiece clamping device 3, the first clamping assembly 413 can immediately provide the next workpiece to be polished to the workpiece clamping device 3 for clamping, facilitating the processing of the next workpiece and improving loading and unloading efficiency.

[0063] The clamping assembly displacement member 43 includes a first displacement member 431, a second displacement member 432, and a third displacement member 433. The first displacement member 431 drives the clamping assembly 41 to move in the left-right direction, the second displacement member 432 drives the clamping assembly 41 to move in the front-back direction, and the third displacement member 433 drives the clamping assembly 41 to move in the up-down direction.

[0064] In this embodiment, the clamping assembly 41 is mounted on the mounting arm 45, which is rotatably connected to the mounting base 46. The mounting base 46 is displaceably connected to the mounting frame 47. The mounting frame 47 includes two opposing uprights 471 and a horizontal frame 472 spanning the two uprights. The first displacement member 431 is a motor that drives the horizontal frame 472 to move left and right relative to the uprights 471 via a lead screw drive. The horizontal frame 472 and the uprights 471 also improve the displacement stability of the horizontal frame 472 through a sliding engagement of a slider and a guide rail. The second displacement member 432 is driven by a motor that drives the mounting base 46 to move back and forth relative to the horizontal frame 472 via a lead screw drive. The mounting base 46 and the horizontal frame 472 also improve the displacement stability of the mounting base 46 through a sliding engagement of a slider and a guide rail. The third displacement member 433 is a motor that drives the mounting arm 45 to move up and down relative to the mounting base 46 via a lead screw drive. The mounting arm 45 and the mounting base 46 also improve the displacement stability of the mounting arm 45 through a sliding engagement of a slider and a guide rail. In other embodiments, the first displacement member 431, the second displacement member 432, and the third displacement member 433 may also be cylinders.

[0065] The clamping assembly rotating member 44 drives the clamping assembly 41 to rotate the workpiece between a first direction and a third direction, giving the clamping assembly 41 a first working position and a second working position. In the first working position, the clamping assembly 41 is used to clamp or release the workpiece on the workpiece loading / unloading device 2. In the second working position, the clamping assembly 41 is used to clamp or release the workpiece on the workpiece holding device 3. In this embodiment, the mounting arm 45 includes an upper mounting arm 451 and a lower mounting arm 452. The upper mounting arm 451 is connected to the mounting base 46, and the lower mounting arm 452 is connected to the upper mounting arm 451. The clamping assembly 41 is connected to the lower mounting arm 452. The clamping assembly rotating member 44 drives the lower mounting arm 452 to rotate relative to the upper mounting arm 451, thereby causing the clamping assembly 41 to rotate. The first working position is when the lower mounting arm 452 rotates to be on the same straight line as the upper mounting arm 451, that is, when the lower mounting arm 452 drives the clamping assembly 41 to rotate to a third direction, so that the clamping assembly 41 can clamp or release the workpiece on the carrier plate 21. The second working position is when the lower mounting arm 452 rotates to be perpendicular to the upper mounting arm 451, that is, when the lower mounting arm 452 drives the clamping assembly 41 to rotate to a first direction, so that the clamping assembly 41 can insert the workpiece into the receiving hole 3111 on the chuck 311. The rotating component 44 of the clamping assembly is a cylinder, which is connected to the lower mounting arm 452. The connection positions of the cylinder and the clamping assembly 41 on the lower mounting arm 452 are respectively located on both sides of the connection position of the upper mounting arm 451, so that when the cylinder is actuated, it can drive the lower mounting arm 452 to rotate the clamping assembly 41. A buffer 48 is mounted on one of the upper mounting arm 451 and the lower mounting arm 452. When the lower mounting arm 452 rotates relative to the upper mounting arm 451, it can contact the other arm to absorb rotational kinetic energy, i.e., absorb the inertial impact force when the clamping assembly 41 rotates. This provides vibration damping and angle adjustment for the rotating part, controlling the positional accuracy of the clamping assembly 41 when it rotates to the first and second working positions. This ensures that the clamping assembly 41 can accurately clamp or release the workpiece on the carrier plate 21 and the chuck 311, and allows the clamping assembly 41 to accurately insert into the receiving hole 3111 in the chuck 311. In this embodiment, the buffer 48 is mounted on the upper mounting arm 451 and can contact the lower mounting arm 452 when it rotates. The buffer 48 can be a damper.

[0066] Please see Figure 10 and combined Figure 4 and Figure 5 The abrasive conveying device 5 is installed in the abrasive working chamber 101 and located behind the polishing chamber 15. The abrasive conveying device 5 includes a discharge mechanism 51 and a feeding mechanism 52.

[0067] Please see Figures 10 to 16The discharge mechanism 51 includes a mounting plate 511, a turntable 512, a first driving component 513, a feeding component 514, a sealing strip 515, a first pulley 516, a first elastic component 517, a support component 518, a first bearing 519, a second bearing 51A, and a connecting component 51B.

[0068] Please see Figures 11 to 14 A mounting plate 511 is vertically arranged inside the abrasive chamber 101, and a turntable 512 is rotatably connected to the mounting plate 511 on the side facing the discharge mechanism 51. The turntable 512 has a material-carrying chamber 5121 and a discharge hole 5122 communicating with the material-carrying chamber 5121. The material-carrying chamber 5121 can store abrasive for polishing workpieces. The discharge hole 5122 is located on the circumferential side of the turntable 512. The centrifugal force of the rotating turntable 512 generates inertial acceleration on the abrasive, accelerating its ejection from the discharge hole 5122, increasing the abrasive ejection speed, thereby improving polishing efficiency and polishing effect. Multiple discharge holes 5122 are spaced around the circumferential side of the turntable 512 to increase the discharge volume.

[0069] Main references Figure 17 In this embodiment, the rear wall of the polishing chamber 15 is a return plate 152, which has a feed port 1521 facing the spray assembly 6. The abrasive ejected from the discharge hole 5122 passes through the feed port 1521 and the spray assembly 6 into the polishing chamber 151 to polish the abrasive particles. The return plate 152 is inclined and located between the abrasive conveying device 5 and the spray assembly 6. The return plate 152 serves as a partition wall between the polishing chamber 151 and the abrasive working chamber 101, with its lower end positioned above the storage chamber 13. A filter screen 14 is located between the lower end of the return plate 152 and the storage chamber 13. The return plate 152 guides the abrasive particles blocked on it to the feed screen and recovers them into the storage chamber 13, thus avoiding abrasive waste. Furthermore, the polishing process is carried out in the polishing chamber 151, and the bottom of the polishing chamber 151 is connected to the internal space of the storage chamber 13. Therefore, the abrasive sprayed into the polishing chamber 151 to polish the workpiece can also be recycled into the storage chamber 13.

[0070] Please see Figure 13 and Figure 14 The turntable 512 is also provided with an acceleration channel 5123, the inner port of the acceleration channel 5123 and the outer port of the acceleration channel 5123 gradually tilt in the direction of rotation of the turntable 512. Figure 14 The direction indicated by the middle arrow is the rotation direction of the turntable 512. The abrasive is further accelerated as it passes through the inclined acceleration channel 5123, further increasing the jetting speed. The turntable 512 is also provided with a feeding port 5124 to facilitate the continuous addition of abrasive to the material chamber 5121.

[0071] Please see Figure 15 and Figure 16 and combined Figure 11 The first driving component 513 is connected to the side of the mounting plate 511 facing away from the turntable 512, and drives the turntable 512 to rotate. The first driving component 513 can be a motor. Please refer to [link / reference]. Figure 11 and Figure 12 The feeding component 514 is located on the side of the mounting plate 511 facing the discharge mechanism 51. The feeding component 514 has a feeding channel 5141 that extends in a bent manner. The lower end of the feeding channel 5141 is connected to the feeding port 5124, and the upper end of the feeding channel 5141 is arranged upward to facilitate feeding material into the loading chamber 5121 through the upper end of the feeding channel 5141.

[0072] Please refer to Figure 11 and Figure 12 The sealing strip 515 is located on the side of the mounting plate 511 facing the discharge mechanism 51. The sealing strip 515 is tensioned and installed on the mounting plate 511 and partially fits tightly against the discharge hole 5122 of the turntable 512 that is not facing the spray assembly 6. The sealing strip 515 forms an arc segment 5151 with a circular bend. The arc segment 5151 fits against part of the peripheral side of the turntable 512 and defines a notch 5152 on the outer side of the remaining peripheral side of the turntable 512. The notch 5152 has a feed port 1521 facing the return plate 152. When the turntable 512 rotates, the sealing strip 515 moves relative to the turntable 512. The discharge hole 5122 facing the arc segment 5151 is always blocked by the arc segment 5151 and cannot be sprayed to the outside of the turntable 512. However, the discharge hole 5122 facing the notch 5152 is not blocked, and the abrasive can be sprayed to the outside of the turntable 512 under the action of centrifugal force. Therefore, the abrasive can be ejected into the ejection assembly 6 through the unsealed discharge port 5122 under the action of centrifugal force. The ejection direction of the abrasive is defined by the sealing strip 515.

[0073] The frame 1 also includes two guide plates 16, and a guide channel is formed between the two guide plates 16. The two guide plates 16 are used to make more of the abrasive ejected from the discharge hole 5122 through the notch 5152 enter the feed port 1521.

[0074] Please see Figures 10 to 12 The first pulley 516 is rotatably connected to the side of the mounting plate 511 facing the discharge mechanism 51. There are multiple first pulleys 516, and the multiple first pulleys 516 are arranged at intervals around the circumference of the turntable 512.

[0075] The sealing strip 515 is made of flexible material and is tautly wrapped around multiple first pulleys 516. Because the arc segment 5151 is taut against a portion of the circumferential surface of the turntable 512, there is friction between the sealing strip 515 and the turntable 512. Therefore, the sealing strip 515 can drive the multiple first pulleys 516 and the turntable 512; that is, the relative friction between the sealing strip 515 and the turntable 512 drives the rotation of each first pulley 516. Converting at least a portion of the friction between the turntable 512 and the sealing strip 515 into the power for the displacement of the sealing strip 515 greatly reduces the influence of friction on the rotational speed of the turntable 512, increases the rotational speed of the turntable 512, increases the centrifugal force of the turntable 512, and thus increases the abrasive ejection speed. In other embodiments, the sealing strip 515 may also be made of a rigid material and fixed to the mounting plate 511. When the turntable 512 rotates, the sealing strip 515 is still displaced relative to the turntable 512. The sealing strip 515 always blocks the discharge hole 5122 on the turntable 512 that is not facing the area to be sprayed.

[0076] Among the multiple first pulleys 516, at least one first pulley 516 is a tensioning pulley 5161. The shaft of the tensioning pulley 5161 is displaceably connected to the mounting plate 511 so as to adjust the tightness of the sealing strip 515 by displacing the tensioning pulley 5161.

[0077] Please see Figure 15 and Figure 16 and combined Figure 11 and Figure 12 As an example, the shaft of the tension wheel 5161 is displaceably connected to the mounting plate 511. The mounting plate 511 is provided with an adjustment groove 5111. The shaft of the tension wheel 5161 is rotatably inserted into the adjustment groove 5111 and can be displaced within the adjustment groove 5111. After the tension wheel 5161 is displaced, it can be locked by fasteners such as bolts.

[0078] Please see Figure 15 The first elastic element 517 is located on the side of the mounting plate 511 facing away from the discharge mechanism 51, driving the shaft of the tensioning wheel 5161 to move in the direction of tensioning the sealing strip 515 within the adjusting groove 5111, and can adaptively adjust the tensioning wheel 5161 to tension the sealing strip 515 in response to changing transmission loads.

[0079] Please refer to Figure 15The support member 518 is located on the side of the mounting plate 511 facing away from the discharge mechanism 51. The hinged end of the support member 518 is rotatably connected to the mounting plate 511. The adjusting groove 5111 extends along the rotation trajectory of the movable end of the support rod. The shaft of the tension wheel 5161 is rotatably connected to the movable end of the support rod. By utilizing the support member 518 to support the tension wheel 5161, the shaft of the tension wheel 5161 can move more stably within the adjusting groove 5111. One end of the helical spring is fixed to the mounting plate 511, and the other end is fixed to the mounting plate 511.

[0080] Please see Figure 15 and Figure 16 and combined Figure 11 and Figure 12 The first bearing 519 is located on the side of the mounting plate 511 facing away from the discharge mechanism 51. The pivot of the hinge end of the support member 518 is rotatably installed inside the first bearing 519, and the hinge end of the support member 518 is clamped between the first bearing 519 and the mounting plate 511, thereby improving the installation stability of the support member 518.

[0081] Multiple second bearings 51A, each corresponding to a first pulley 516, are located on the side of the mounting plate 511 facing away from the discharge mechanism 51. The shafts of the first pulleys 516 on the side of the mounting plate 511 facing the discharge mechanism 51 pass through the mounting plate 511 and are rotatably installed inside the second bearings 51A, ensuring rotational stability.

[0082] In this embodiment, three first pulleys 516 are provided and arranged in a triangular pattern. The shafts of two first pulleys 516 located at both ends of the arc segment 5151 are fixedly connected to the mounting plate 511, and the shaft of the third first pulley 516 is displaceably connected to the mounting plate 511 as a tensioning pulley 5161. Two first pulleys 516 may also be provided. Preferably, the diameter of the two first pulleys 516 is larger than the diameter of the turntable 512, and they are configured such that after the sealing strip 515 is tensioned and adheres to a portion of the circumferential surface of the turntable 512, contact between the sealing strips 515 is avoided. Embodiments with other numbers of first pulleys 516 are not detailed here.

[0083] It is understood that the first pulley 516, the first elastic element 517, the support element 518, the first bearing 519, and the second bearing 51A constitute the tensioning assembly of the tensioning sealing belt 515. Please refer to [link / reference]. Figure 10 The connector 51B is connected to the side of the mounting plate 511 facing the discharge mechanism 51, and the connector 51B is used to install the discharge mechanism 51.

[0084] Please refer to Figure 10The feeding mechanism 52 is located adjacent to the discharging mechanism 51 on one side. The feeding mechanism 52 adds abrasive to the material loading chamber 5121 through the feeding port 5124 to ensure that the material loading chamber 5121 has sufficient abrasive. The feeding mechanism 52 includes a baffle 521, a second pulley 522, a conveyor belt 523, a material conveying component 524, a second driving component 525, a rotating component 526, a second elastic component 527, a first scraper 528, and a second scraper 529.

[0085] Please see Figure 10 The baffle 521 is connected to the connector 51B. The baffle 521 includes a first plate 5211, a second plate 5212, and a third plate 5213. The first plate 5211 and the second plate 5212 are arranged opposite to each other, and the third plate 5213 connects the first plate 5211 and the second plate 5212, and encloses them to form an installation space.

[0086] The first plate 5211 is connected to the connector 51B.

[0087] Please see Figure 18 The second pulley 522 is disposed within the installation space and rotatably connected to the first plate 5211 and the second plate 5212. Multiple second pulleys 522 are arranged vertically at intervals. The conveyor belt 523 is disposed within the installation space and is drivenly connected to the multiple second pulleys 522. In this embodiment, there are two second pulleys 522; the upper second pulley 522 defines the top end of the conveyor belt 523, and the lower second pulley 522 defines the bottom end of the conveyor belt 523.

[0088] Please continue reading Figure 18 The conveyor belt 524 is located within the installation space and connected to the outside of the conveyor belt 523. The conveyor belt 524 is provided with a conveyor trough 5240, which is used to drive the abrasive to rise.

[0089] Please see Figure 18 and Figure 20 The two opposite outer sides of the conveyor belt 523 are the loading side 5231 and the unloading side 5232, respectively. When the conveyor belt 524 is located on the loading side 5231, the conveyor belt chute 5240 is arranged facing upwards; when the conveyor belt 524 is located on the unloading side 5232, the conveyor belt chute 5240 is arranged facing downwards.

[0090] As the conveyor belt 524 passes the top of the conveyor belt 523, it flips from the loading side 5231 to the unloading side 5232. The upward-facing conveyor belt trough 5240 gradually flips downward, pouring the abrasive material in the conveyor belt trough 5240 into the upper end of the feeding channel 5141. Figure 20 The arrow in the diagram indicates the direction of rotation of the second pulley 522.

[0091] The lower end of the conveyor belt 523 is inserted into the rear end of the top opening of the storage chamber 13. The rear end of the top opening of the storage chamber 13 serves as the discharge port and is connected to the abrasive working chamber 101. The storage chamber 13 can store a large amount of abrasive, ensuring the abrasive supply. The feeding mechanism 52 continuously lifts the abrasive upwards and adds it to the discharge mechanism 51. The front end of the top opening of the storage chamber 13 connects to the bottom of the polishing chamber 151. The front end of the top opening of the storage chamber 13 serves as the inlet and is connected to the polishing chamber 151. The inlet extends downwards to the discharge port, which is more conducive to the abrasive falling and being recycled. The abrasive circulation is achieved through the abrasive recycling structure that connects the return plate 152 and the bottom of the polishing chamber 151 to the storage chamber 13.

[0092] Please see Figure 18 and Figure 19 The conveyor belt 524 includes a clamping plate 5241 and side rails 5242. The clamping plate 5241 extends along the width direction of the conveyor belt 523, is connected to the conveyor belt 523, and is arranged at an angle relative to the conveyor belt 523. Each clamping plate 5241 corresponds to two side rails 5242, which extend along the length direction of the conveyor belt 523, are connected to the conveyor belt 523, and are respectively connected to both ends of the clamping plate 5241. A conveyor belt chute 5240 is formed between the conveyor belt 523, one clamping plate 5241, and two side rails 5242. The clamping plate 5241 and the side rails 5242 can be made of flexible material to facilitate passage through the top and bottom ends of the conveyor belt 523, which has a rounded transition.

[0093] Please see Figure 15 and Figure 16 and combined Figure 10 The second drive unit 525 is connected to the side of the mounting plate 511 facing away from the turntable 512, and one of the second pulleys 522 of the second drive unit 525 rotates.

[0094] Please see Figure 18 A rotating member 526 is disposed on the inner side of the conveyor belt 523 and rotatably connected to the first plate 5211 and the second plate 5212. The rotating member 526 abuts against the inner side of the conveyor belt 523, forming a support on the inner side of the conveyor belt 523. Multiple rotating members 526 are provided, each abutting against two opposite inner sides of the conveyor belt 523. The rotating member 526 can be a rotating shaft or a roller.

[0095] Please see Figure 21Among the multiple rotating components 526, at least one rotating component 526 includes a connecting rod 5261, a first rotating portion 5262, and a second rotating portion 5263. The connecting rod 5261 has a U-shaped structure and includes a first rod portion 52611, a second rod portion 52612, and a third rod portion 52613. The first rod portion 52611 and the second rod portion 52612 are arranged opposite to each other, and the third rod portion 52613 connects the first rod portion 52611 and the second rod portion 52612. The first rod portion 52611 is rotatably connected to the first plate 5211, and the third rod portion 52613 can rotate about the first rod portion 52611 as a pivot. The first rotating portion 5262 is rotatably connected to the first rod portion 52611 and abuts against an inner side of the conveyor belt 523. The second rotating portion 5263 is rotatably connected to the third rod portion 52613.

[0096] The second elastic element 527 is disposed on the inner side of the conveyor belt 523. The second elastic element 527 acts on the first rod portion 52611 and the third rod portion 52613, possessing an elastic force that drives the third rod portion 52613 to rotate to a horizontal position with the first rod portion 52611, causing the second rotating portion 5263 to abut against the other opposite inner side of the conveyor belt 523. The second elastic element 527 can adaptively adjust the first rotating portion 5262 and the second rotating portion 5263 to abut against the two opposite inner sides of the conveyor belt 523 in response to changing transmission loads, thereby improving transmission stability. The second elastic element 527 can be a torsion spring.

[0097] Please see Figure 18 A first scraper 528 is disposed on the inner side of the conveyor belt 523, and the first scraper 528 contacts the second pulley 522 at an angle to scrape off the abrasive adhering to the second pulley 522. See also... Figure 18 The second scraper 529 is located on the inner side of the conveyor belt 523. The second scraper 529 contacts the inner side of the conveyor belt 523 at an angle and is used to scrape off the abrasive adhering to the inner side of the conveyor belt 523.

[0098] Please see Figure 17 and combined Figure 4 The spray assembly 6 is installed inside the polishing chamber 151. The spray assembly 6 is used to further accelerate the abrasive ejected by the abrasive delivery device 5, thereby further improving the polishing effect.

[0099] The spraying assembly 6 includes a spray gun 61, a pneumatic component, and an air pipe 62. The spray gun 61 is provided with a spraying channel, which has a receiving port and a spraying port. The receiving port is used to receive the abrasive sprayed by the abrasive conveying device 5, and the spraying port is used to spray the abrasive onto the workpiece held on the workpiece clamping device 3 for polishing.

[0100] The spray gun 61 is also provided with an anti-clogging groove 611. The anti-clogging groove 611 is located on the tube wall of the spray gun 61 and connects the spray channel and the outside of the spray gun 61. The anti-clogging groove 611 is designed to prevent abrasive from clogging the spray channel.

[0101] The anti-clogging groove 611 extends to the receiving port and the spraying port at both ends, respectively, to more effectively prevent abrasive from clogging the spraying channel. In this embodiment, the spray gun 61 is connected to the return plate 152, with the receiving port facing the feed port 1521, so that the abrasive sprayed from the discharge port on the turntable 512 to the feed port 1521 can enter the receiving port.

[0102] The spray gun 61 is displaceably connected to the return plate 152. The position of the receiving port relative to the feed port 1521 can be adjusted by moving the spray gun 61, allowing more abrasive to enter the receiving port. The spray gun 61 can be displaceably connected by connecting it to a first connecting member 63. The first connecting member 63 has a slotted hole, and bolts are passed through the slotted hole to connect the first connecting member 63 to the return plate 152. The installation position of the spray gun 61 is adjusted by displacing the slotted hole relative to the bolts.

[0103] The spray gun 61 includes a first piece 612, a second piece 613, and a third piece 614. The first piece 612 and the second piece 613 are arranged opposite to each other, and the third piece 614 is connected to the first piece 612 and the second piece 613, and forms a spray channel with a bottom opening below the third piece 614. The bottom opening serves as an anti-clogging groove 611.

[0104] A pneumatic component provides airflow to accelerate the abrasive through the spray channel, increasing the abrasive's spray velocity and thus improving the polishing effect. In this embodiment, the pneumatic component generates low pressure at the spray nozzle, making the air pressure at the nozzle lower than the air pressure at the receiving port. This generates airflow to the abrasive entering the spray channel, accelerating it through the channel. The low pressure at the spray nozzle can be generated by the pneumatic component creating a high-speed airflow. According to the Venturi effect, low pressure is generated near a high-speed flowing fluid, creating an adsorption effect. The abrasive in the spray channel is accelerated through the channel under the adsorption force of this low-pressure adsorption at the nozzle.

[0105] The air pipe 62 is provided with a gas channel, which has an inlet and an outlet. The inlet is connected to the pneumatic component, and the outlet is adjacent to the injection port and faces the direction of the injection port towards the workpiece. This allows the pneumatic component to not only generate low pressure at the injection port, causing the abrasive in the injection channel to be accelerated and ejected from the injection port, but also to further accelerate the abrasive ejected from the injection port under the action of the airflow before it is ejected onto the workpiece.

[0106] The air pipe 62 is movable and mounted on the frame 1, allowing adjustment of the relative position of the air outlet and the spray nozzle to ensure optimal abrasive spraying. The air pipe 62 can be connected to a second connector 64, which has a slotted hole. A bolt passes through the slotted hole to connect the second connector 64 to the first connector 63. The air pipe 62's position is adjusted by displacing the slotted hole relative to the bolt. The polishing machine also includes an abrasive stirring device 7, installed within the abrasive chamber 101 and located below the polishing chamber 15. The abrasive stirring device 7 is used to stir and prepare abrasives, such as grinding particles and elastic gel spheres. Grinding particles and elastic gel spheres are added to the abrasive stirring device 7 along with a certain proportion of water, and stirred to prepare wet elastic gel spheres containing grinding particles.

[0107] Please see Figure 22 and combined Figure 4 The frame 1 also includes a mixing chamber, which houses an abrasive mixing device 7. The abrasive mixing device 7 includes a mixing tank 71 and a rotating component 526 for the mixing tank 71. The internal space of the mixing tank 71 is used to hold the components for preparing the abrasive. The rotating component 526 drives the mixing tank 71 to rotate, thereby mixing the components for preparing the abrasive. The rotating component 526 can be a motor.

[0108] Please see Figure 23 and combined Figure 4 The polishing machine also includes a lifting assembly 8. The lifting assembly 8 is installed inside the polishing chamber 151. The lifting assembly 8 includes a lifting door 81 and a lifting drive 82. A first connecting window is provided on the right side wall of the polishing chamber 15, located between the polishing chamber 15 and the loading / unloading chamber 102. The workpiece clamping device 4 can move the workpiece in and out of the first connecting window when clamping it, allowing the workpiece to move between the workpiece loading / unloading device 2 and the workpiece clamping device 3. The lifting drive 82 drives the lifting door 81 to open and close the first connecting window. When the first connecting window is open, i.e., when the polishing chamber 151 is connected to the loading / unloading chamber 102, the workpiece can enter and exit the first connecting window. When the first connecting window is closed, i.e., when the polishing chamber 151 and the loading / unloading chamber 102 are isolated from each other, dust generated from polishing workpieces in the polishing chamber 151 can be prevented from contaminating the loading / unloading chamber 102. The lifting drive 82 can be a cylinder.

[0109] In this embodiment, the lifting assembly 8 is disposed within the polishing chamber 151 and installed on the partition wall between the polishing chamber 151 and the loading / unloading chamber 102. The frame 1 also includes a partition that divides the internal space of the frame 1 into the loading / unloading chamber 102 and the polishing chamber 151. The partition is provided with a second connecting window that connects the loading / unloading chamber 102 and the polishing chamber 151. The second connecting window connects to the first connecting window. When the lifting drive 82 drives the lifting door 81 to open or close the first connecting window, it can simultaneously open and close the second connecting window. Of course, in other embodiments, the partition can directly serve as the right side wall of the polishing chamber 15.

[0110] The workpiece clamping device 3 moves in the first direction, either towards or away from the lifting assembly 8. When the polishing chamber 151 is connected to the loading and unloading chamber 102, the clamping assembly 41 moves the workpiece between the two chambers.

[0111] When the polishing chamber 151 is connected to the loading and unloading chamber 102, the clamping component displacement member 43 drives the two clamping components 41 to clamp the workpiece to be polished in the loading area clamped on the first clamping component 413 and transfer it from the loading and unloading chamber 102 to the polishing chamber 151. The workpiece is then rotated from the third direction to the first direction by the clamping component rotation member 44. Driven by the clamping component drive member 42 and the clamping component displacement member 43, the second clamping component 414 unloads the polished workpiece from the workpiece clamping device 3 along the first direction, and the first clamping component 413 loads the workpiece to be polished into the workpiece clamping device 3 along the first direction, thereby improving the efficiency of changing the workpiece clamping device 3 and thus improving the polishing efficiency.

[0112] Please see Figure 1 and Figure 4 The polishing chamber 151 has two through holes 17 on its sidewall opposite to the spray assembly 6, and its top has an opening for pouring abrasive into the storage chamber 13. The through holes 17 connect the polishing chamber 151 to the outside of the polishing machine, and allow workpieces to enter and exit the polishing chamber 151. The spray assembly 6 is also used to spray abrasive onto the workpieces that enter the polishing chamber 151 through the through holes 17 for polishing. The workpiece to be polished can be directly held in and out of the polishing chamber 151. In this embodiment, the through holes 17 penetrate the front sidewall of the polishing chamber 15 and the front side of the housing 12. By setting the through holes 17, the polishing modes of the polishing machine are enriched, which is particularly suitable for polishing when the number of workpieces is small. Polishing can be completed by the action of the abrasive conveying device 5 and the spray assembly 6.

[0113] Please see Figure 4 and Figure 5 The polishing machine also includes a dust removal device 9, which is installed inside the abrasive chamber 101 and adjacent to the storage chamber 13. The dust suction port of the dust removal device 9 connects the abrasive chamber 101 and the storage chamber 13.

[0118] According to another aspect of this disclosure, a polishing system is also provided, including the polishing apparatus, external input unit, sensing unit, and control unit of any of the above embodiments.

[0119] The sensing unit includes a first and a second sensing device respectively installed in the loading / unloading chamber 102 and the polishing chamber 151. The first and second sensing devices are used to detect the positions of the workpiece clamping device 4 and the workpiece holding device 3 and send first and second position signals, respectively.

[0120] An external input unit is mounted on rack 1 and includes a control panel and a start / stop button. The control panel is used to receive preset information and send preset signals. The start / stop button is used to provide external input and send start and stop signals.

[0121] The control unit receives start signals, stop signals, and first and second position signals. Based on these signals and preset signals, it controls the operation of the abrasive conveying device 5, the workpiece clamping device 4, and the workpiece holding device 3. It also determines whether each device has reached its designated position based on the first and second position signals. When each device reaches its designated position, it controls it to perform a preset action.

[0122] Specifically, in the polishing equipment, the polishing program can be set by receiving preset information through the control panel. Pressing the start / stop button sends a start signal to the control unit. The control unit controls the workpiece clamping device 4 to operate according to the preset signal sent by the control panel. The clamping component displacement component 33 drives the first clamping component 413 and the second clamping component 414 to move to the loading area. The first clamping component drive component 421 drives the first clamping component 413 to clamp the workpiece to be polished in the loading area, and then moves it to the left side of the loading / unloading chamber 102 near the workpiece clamping device 3. The control component rotation component 44 drives the two clamping components 41 to rotate from the third direction to the first direction. When the first sensor detects that the workpiece clamping device 4 is in the specified position, it sends a first position signal to the control unit. The control unit then controls the workpiece clamping device 3 to operate. The clamping component displacement member 33 drives the clamping component 31 to move to the right along the first direction to the right side of the polishing chamber 151, close to the workpiece clamping component 41. When the second sensor detects that the workpiece clamping device 3 is in the specified position, it sends a second position signal to the control unit. The control unit then controls the workpiece clamping device 4 to operate. The second clamping component drive member 422, in conjunction with the clamping component displacement member 33, drives the second clamping component 414 to remove the polished workpiece from the workpiece clamping device 4. The first clamping drive member, in conjunction with the clamping component displacement member 33, drives the first clamping component 413 to load the workpiece to be polished into the workpiece clamping device 3 along the first direction.

[0123] The control unit then controls the operation of the workpiece clamping device 3. The clamping component displacement member 33 drives the clamping component 31 to move the workpiece to be polished to the left along the first direction to the spraying component 6. When the second sensor detects that the workpiece clamping device 3 is in this position, it sends a second position signal to the control unit. The control unit then controls the abrasive conveying device 5 to operate, lifting the abrasive in the storage chamber 13 upwards and centrifugally spraying it along the spraying component 6 onto the workpiece to be polished on the workpiece clamping device 3 for polishing. It should be noted that when polishing is not being performed, the control unit controls the abrasive conveying device 5 to stop operating to reduce abrasive wear. On the other side, the clamping component displacement member 33 drives the first clamping component 413, the second clamping component 414, and the polished workpiece clamped by the second clamping component 414 to move to the unloading area. Driven by the clamping component rotating member 44, the workpiece rotates from the first direction to the third direction, unloading the polished workpiece into the unloading area, thus completing one polishing process. After the workpiece to be polished is polished, press the start / stop button to send a stop signal to the control unit. The control unit controls the workpiece clamping device 4, the workpiece gripping device and the workpiece holding device 3 to stop operating according to the preset signal sent by the control panel.

[0124] It is understood that in the embodiment with lifting component 8, when the first clamping component drive 421 drives the first clamping component 413 to clamp the workpiece to be polished in the loading area and move it to the left side of the loading and unloading chamber 102 near the workpiece clamping device 3, the first sensing device detects that the workpiece clamping device 4 is in that position and sends a first position signal to the control unit. The control unit also controls the lifting component 8 to operate, and the lifting drive 82 opens the lifting door 81, so that the workpiece to be polished and the polished workpiece can be transferred between the loading and unloading chamber 102 and the polishing chamber 151.

[0125] When the clamping assembly displacement component 33 drives the clamping assembly 31 to move the workpiece to be polished to the left along the first direction to the spraying assembly 6, the second sensor detects that the workpiece clamping device 3 is in that position and sends a second position signal to the control unit. The control unit then controls the lifting assembly 8 to operate, and the lifting drive component 82 closes the lifting door 81 to prevent grinding waste from overflowing during the polishing process. Based on this polishing system, the stability and efficiency of the polishing process are improved.

[0126] The above are merely preferred embodiments of this disclosure and are not intended to limit the scope of this disclosure. Various modifications and variations can be made to these embodiments by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
