Description

Technical Field

[0001] This application relates to the field of surface treatment equipment technology, specifically to a grinding device. Background Technology

[0002] In existing industrial production environments, especially in fields such as parts manufacturing, precision machining, and mold forming, grinding is an indispensable and important process. It aims to eliminate burrs and smooth the surface of workpieces through fine treatment in order to achieve the expected product quality and specifications.

[0003] However, the grinding equipment and technologies commonly found on the market still have many issues that need improvement. On the one hand, traditional grinding equipment often has a relatively fixed structural design and simple functional modules, making it difficult to achieve continuous and efficient grinding from all angles and directions. This significantly restricts the improvement of production efficiency and product quality. On the other hand, the grinding tools used in the grinding process (such as grinding wheels, sanding belts, polishing discs, etc.) wear down continuously under high-speed operation and need to be replaced regularly to maintain good grinding results. However, current grinding equipment generally suffers from low automation and inconvenient operation in the part replacement process, usually requiring manual intervention. This not only prolongs downtime and affects the continuity of the production line, but also increases the safety risks for workers. Summary of the Invention

[0004] In view of the above, it is necessary to propose a grinding equipment to achieve all-round and efficient grinding of workpieces and automatic replacement of grinding parts, thereby improving the accuracy, efficiency and safety of grinding operations.

[0005] This application provides a grinding device, comprising: a base, including a base, a support frame connected to the base, a longitudinal drive mechanism connected to the base and spaced apart from the support frame, and a vertical drive mechanism connected to the support frame; a workpiece positioning mechanism connected to the longitudinal drive mechanism, the workpiece positioning mechanism being used to fix a workpiece, and the longitudinal drive mechanism being used to drive the workpiece positioning mechanism to move along a first direction; a grinding device connected to the vertical drive mechanism, including a rotating component and a plurality of grinding components spaced apart from the rotating component along a second direction, each grinding component being provided with a detachable grinding element; and a scraper mechanism connected to the longitudinal drive mechanism or the workpiece positioning mechanism, used to correspond to multiple... The grinding assembly includes a vertical drive mechanism that drives the rotating assembly to descend to a preset position, during which the vertical drive mechanism drives the scraper mechanism to move along the first direction and scrape into the grinding assembly and the corresponding connected grinding part; and a replacement device connected to the grinding device, the replacement device including a plurality of pushing mechanisms arranged at a preset angle to a third direction and spaced apart along the second direction, the pushing mechanism being used to store a plurality of the grinding parts, the rotating assembly being used to rotate the plurality of the grinding assemblies to a position corresponding to the pushing mechanism, the pushing mechanism pushing and installing the stored grinding parts onto the corresponding grinding assembly; wherein, the first direction, the second direction and the third direction are perpendicular to each other.

[0006] The aforementioned grinding equipment uses a workpiece positioning mechanism to position the workpiece. Driven by a longitudinal drive mechanism, the workpiece positioning mechanism moves towards the grinding device. The grinding device contains a grinding assembly. When the workpiece positioning mechanism and the workpiece move below the grinding device, the grinding assembly grinds the upper surface of the workpiece. When the workpiece positioning mechanism and the workpiece move to a position adjacent to the grinding device in the first direction, the vertical drive mechanism drives the grinding device to move to the same horizontal plane as the workpiece. At this point, a rotating component rotates the grinding assembly so that the grinding assembly faces the side of the workpiece, thus grinding the side of the workpiece. This allows for all-around grinding of the workpiece. When changing grinding parts, a scraper mechanism moves towards the grinding device under the drive of the longitudinal drive mechanism, inserting the scraper mechanism between the grinding assembly and the corresponding connected grinding part. The vertical drive mechanism moves the grinding assembly away from the scraper mechanism, causing the scraper to remove the grinding part. The vertical drive mechanism then drives the grinding device to move along a third direction to the position of the corresponding replacement device. The rotating component rotates multiple grinding components to correspond with the pushing mechanism. The pushing mechanism pushes the stored grinding parts onto the corresponding grinding components, completing the automatic replacement of grinding parts. The above-mentioned grinding equipment can efficiently grind workpieces from all directions, and can automatically replace grinding parts through the cooperation of the scraper mechanism and the replacement device, reducing the frequency of manual operation and improving the automation level and safety of grinding part replacement.

Detailed Implementation

[0016] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0017] The embodiments of this application will be further described below with reference to the accompanying drawings. For ease of understanding and explanation, please refer to... Figure 1 In this embodiment, the X-axis direction is defined as the second direction, the Y-axis direction as the first direction, and the Z-axis direction as the third direction.

[0018] Please see Figure 1 This application provides a grinding device 100 for grinding workpiece 200 (see [link]). Figure 3 The workpiece 200 can be the casing or frame of electronic products such as mobile phones and tablets. The areas of the workpiece 200 that need to be polished can include multiple sides and the top and bottom surfaces. The polishing equipment 100 includes a base 10, a workpiece positioning mechanism 20, a polishing device 30, a scraper mechanism 40, and a changing device 50.

[0019] Specifically, please see Figure 1The base 10 includes a base 11, a support frame 12 connected to the base 11, a longitudinal drive mechanism 13 connected to the base 11 and spaced apart from the support frame 12, and a vertical drive mechanism 14 connected to the support frame 12. It can be understood that the base 11 is disposed in the XY plane, the support frame 12 is disposed in the YZ plane, the longitudinal drive mechanism 13 can be a linear module or other mechanism capable of driving other structures to move along the Y-axis, and the vertical drive mechanism 14 can be a linear module or other mechanism capable of driving other structures to move along the Z-axis.

[0020] Please see Figure 2 and Figure 3 The workpiece positioning mechanism 20 is connected to the longitudinal drive mechanism 13. The workpiece positioning mechanism 20 is used to fix the workpiece 200, and the longitudinal drive mechanism 13 is used to drive the workpiece positioning mechanism 20 to move along the Y-axis. It can be understood that in order to achieve simultaneous grinding of multiple workpieces 200, multiple workpiece positioning mechanisms 20 can be provided, such as four, five, six, etc. Multiple workpiece positioning mechanisms 20 are spaced apart on the longitudinal drive mechanism 13 along the X-axis to fix multiple workpieces 200 at the same time.

[0021] Please see also Figure 4 The grinding device 30 is connected to the vertical drive mechanism 14 and includes a rotating component 31 and multiple grinding components 32 spaced apart along the X-axis on the rotating component 31. Each grinding component 32 is provided with a detachable grinding element 33. The number of grinding components 32 can be four, five, six, eight, ten, twelve, etc. The number of grinding components 32 can be the same as the number of workpiece positioning mechanisms 20, so that the grinding components 32 can grind the workpieces 200 on multiple workpiece positioning mechanisms 20 at the same time. Alternatively, the number of grinding components 32 can be twice the number of workpiece positioning mechanisms 20. In this case, the grinding components 32 can be arranged in multiple rows, and the number of grinding components 32 in each row can be the same as the number of workpiece positioning mechanisms 20. The grinding assembly 32 and the grinding piece 33 can be connected by Velcro or similar adhesive. The grinding piece 33 may have a through hole. The end of the grinding assembly 32 used to connect to the grinding piece 33 may have a protrusion corresponding to the through hole. When the grinding piece 33 is connected to the grinding assembly 32, the protrusion is inserted into the corresponding through hole of the grinding piece 33 to improve the stability of the connection between the grinding piece 33 and the grinding assembly 32.

[0022] The scraper mechanism 40 is connected to the longitudinal drive mechanism 13 or the workpiece positioning mechanism 20, and is used to correspond to multiple grinding components 32. When the vertical drive mechanism 14 drives the rotating component 31 to descend to a preset position, the longitudinal drive mechanism 13 drives the scraper mechanism 40 to move along the Y-axis and scrape into the space between the grinding component 32 and the corresponding connected grinding part 33. The number of scraper mechanisms 40 can be four, five, six, etc., and the number of scraper mechanisms 40 is the same as the number of grinding components 32 in the same column on the rotating component 31, so that the scraper mechanism 40 can scrape off the grinding parts 33 on the grinding components 32 in the same column at the same time. The process of the scraper mechanism 40 disassembling the grinding part 33 is roughly as follows: the vertical drive mechanism 14 drives the rotating component 31 to descend, the rotating component 31 drives multiple grinding components 32 in the same row to rotate to the position corresponding to the scraper mechanism 40, then the longitudinal drive mechanism 13 drives the scraper mechanism 40 to move in the opposite direction of the Y axis, thereby causing the scraper mechanism 40 to scrape into the space between the grinding component 32 and the corresponding connected grinding part 33, and then the vertical drive mechanism 14 drives the rotating component 31 and the grinding component 32 to move in the Z axis direction, thereby causing the grinding part 33 to separate from the grinding component 32.

[0023] Please see also Figure 5 and Figure 6 The replacement device 50 is connected to the grinding device 30. The replacement device 50 includes multiple pushing mechanisms 51 arranged at a preset angle to the Z-axis and spaced apart along the X-axis. The pushing mechanisms 51 are used to store multiple grinding parts 33. The rotating component 31 is used to rotate multiple grinding components 32 to correspond to the pushing mechanisms 51. When the pushing mechanism 51 pushes the stored grinding parts 33 onto the corresponding grinding components 32, the pushing mechanism 51 pushes the stored grinding parts 33 onto the corresponding grinding components 32. The pushing mechanism 51 can be set to five, ten, etc. After the scraper 43 assembly removes the grinding parts 33 from the grinding components 32, the vertical drive mechanism 14 drives the rotating component 31 and the grinding components 32 to move along the Z-axis to the position corresponding to the replacement device 50. Then the rotating component 31 rotates the grinding components 32 to correspond to the pushing mechanism 51. The pushing mechanism 51 pushes the stored new grinding parts 33 onto the corresponding grinding components 32, thus completing the automatic replacement of the grinding parts 33.

[0024] The aforementioned grinding equipment 100 can position the workpiece 200 through the workpiece positioning mechanism 20. The workpiece positioning mechanism 20 can move towards the grinding device 30 under the drive of the longitudinal drive mechanism 13. The grinding device 30 is provided with a grinding component 32. When the workpiece positioning mechanism 20 and the workpiece 200 move to below the grinding device 30, the grinding component 32 can grind the upper surface of the workpiece 200. When the workpiece positioning mechanism 20 and the workpiece 200 move to be adjacent to the grinding device 30 in the Y-axis direction, the vertical drive mechanism 14 can drive the grinding device 30 to move to be on the same horizontal plane as the workpiece 200. At this time, the rotating component 31 rotates the grinding component 32 so that the grinding component 32 is opposite to the side of the workpiece 200, so as to grind the side of the workpiece 200. In this way, the workpiece 200 can be ground from all directions. When replacing the grinding part 33, the scraper mechanism 40 moves towards the grinding device 30 under the drive of the longitudinal drive mechanism 13, thereby inserting the scraper mechanism 40 between the grinding assembly 32 and the corresponding connected grinding part 33. The vertical drive mechanism 14 drives the grinding assembly 32 away from the scraper mechanism 40, thereby causing the scraper 43 to remove the grinding part 33. Then, the vertical drive mechanism 14 drives the grinding device 30 to move along the Z-axis to the position of the corresponding replacement device 50. The rotating assembly 31 rotates multiple grinding assemblies 32 to the corresponding position of the pushing mechanism 51. The pushing mechanism 51 pushes the stored grinding part 33 onto the corresponding grinding assembly 32, completing the automatic replacement of the grinding part 33. The above-mentioned grinding equipment 100 can efficiently grind the workpiece 200 from all directions, and can automatically replace the grinding part 33 through the cooperation of the scraper mechanism 40 and the replacement device 50, reducing the frequency of manual operation and improving the automation level and safety of the grinding part 33 replacement.

[0025] In some embodiments, see Figure 1 and Figure 4 The grinding equipment 100 also includes an alignment mechanism 60, which includes a sensor drive 61 and a sensor 62. The sensor drive 61 is fixedly connected to the support frame 12, and the sensor 62 is connected to the sensor drive 61. The sensor 62 is used to detect the thickness of the grinding part 33 when the vertical drive mechanism 14 moves the rotating assembly 31 and the grinding part 33 along the Z-axis to correspond to the sensor 62. The sensor drive 61 is used to drive the sensor 62 to move along the X-axis to adjust the position of the sensor 62.

[0026] The sensor drive unit 61 can be a telescopic cylinder, telescopic motor, etc., and the sensor 62 can be a thickness detector or distance detector, etc. The sensor drive unit 61 is used to move the sensor 62 in the X-axis direction so that the sensor 62 corresponds to the position of the grinding part 33 to be detected. Multiple sensors 62 can be provided, such as five or ten, so that during detection, each sensor 62 corresponds to the grinding part 33 on the grinding assembly 32. It can be understood that the thickness of each grinding part 33 is different, and after each grinding part 33 is connected to the corresponding grinding assembly 32, the distance between the side of the grinding part 33 used for grinding the workpiece 200 and the grinding assembly 32 may be different. Therefore, before grinding the workpiece 200, it is necessary to detect the thickness of each grinding part 33, that is, to detect the distance between the side of each grinding part 33 used for grinding the workpiece 200 and the corresponding grinding assembly 32.

[0027] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The grinding equipment 100 also includes an adjustment assembly 70, which includes a vertical adjustment member 71 connected to the longitudinal drive mechanism 13 and a longitudinal adjustment member 72 connected to the vertical adjustment member 71. The workpiece positioning mechanism 20 is connected to the longitudinal adjustment member 72. The vertical adjustment member 71 and the longitudinal adjustment member 72 are used to move the position of the workpiece positioning mechanism 20 in the Z-axis direction and the Y-axis direction according to the position of the workpiece 33, so that the workpiece 200 positioned by the workpiece positioning mechanism 20 corresponds to the position of the workpiece 33.

[0028] The vertical adjustment component 71 can be a cylinder, etc., and the longitudinal adjustment component 72 can be a cylinder, etc. The vertical adjustment component 71 can adjust the position of the longitudinal adjustment component 72 and the workpiece positioning mechanism 20 in the Z-axis direction, and the longitudinal adjustment component 72 can adjust the position of the workpiece positioning mechanism 20 in the Y-axis direction. That is, through the cooperation of the vertical adjustment component 71 and the longitudinal adjustment component 72, the position of the workpiece 200 in the YZ plane can be adjusted.

[0029] It is understandable that after the grinding part 33 is connected to the grinding assembly 32, the connection positions of different grinding parts 33 and their corresponding grinding assemblies 32 may differ, and the thickness of different grinding parts 33 may also differ. This results in differences in the position of the side of different grinding parts 33 used for grinding the workpiece 200. After the sensor 62 detects the distance between the side of each grinding part 33 used for grinding the workpiece 200 and the corresponding grinding assembly 32, the corresponding vertical adjustment part 71 and longitudinal adjustment part 72 adjust the position of the workpiece 200 to compensate for the position of different grinding parts 33, flexibly adjust the position of the workpiece 200, ensure the alignment accuracy between the workpiece 200 and the grinding part 33, and thus improve the grinding quality.

[0030] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The replacement device 50 also includes a bracket 52, which is connected to the vertical drive mechanism 14 and extends along the X-axis. The pushing mechanism 51 includes a barrel drive 511, a connecting frame 512, a barrel 513, and a pushing drive 514. The barrel drive 511 is connected to the bracket 52, the connecting frame 512 is connected to the barrel drive 511, and the barrel 513 is detachably connected to the connecting frame 512. The barrel 513 is used to store the grinding parts 33. The pushing drive 514 is connected to the connecting frame 512 and is correspondingly arranged with the barrel 513. The barrel drive 511 is used to drive the connecting frame 512 to move towards the grinding assembly 32 so that the barrel 513 is opposite to the grinding assembly 32. The pushing drive 514 is used to push and install the grinding parts 33 stored in the barrel 513 onto the corresponding grinding assembly 32.

[0031] The bracket 52 is roughly U-shaped, comprising a first support plate 521 and a second support plate 522. The first support plate 521 is connected to the vertical drive mechanism 14, and a guide hole 523 is provided on the first support plate 521. The second support plate 522 is used to connect to and support the barrel drive component 511. The barrel drive component 511 can be a cylinder, etc. The connecting frame 512 can be a plate-like structure, and a strip-shaped hole (not shown) is provided on the connecting frame 512. One end of the strip-shaped hole corresponds to the push drive component 514, and the other end of the strip-shaped hole is away from the push drive component 514. When installing the barrel 513, the barrel 513 is inserted from the end away from the push drive component 514 through the strip-shaped hole, and then the barrel 513 is moved along the strip-shaped hole to the end corresponding to the push drive component 514. When disassembling the barrel 513, the barrel 513 is moved in the opposite direction. It is understood that after the material cylinder 513 is installed, its position corresponds to the guide hole 523. When the material cylinder drive component 511 drives the connecting frame 512 to move towards the grinding assembly 32, the material cylinder 513 slides into the guide hole 523, at which time the guide hole 523 guides the position of the material cylinder 513. The material cylinder 513 is roughly tubular in shape. The radius of the end of the material cylinder 513 away from the pusher drive component 514 is smaller than the radius of the grinding part 33 to prevent the grinding part 33 from slipping. When the pusher drive component 514 pushes the grinding part 33, the grinding part 33 can be detached from the material cylinder 513. The pusher drive component 514 can be a telescopic cylinder to push the grinding part 33 out of the material cylinder 513 and install it onto the corresponding grinding assembly 32.

[0032] When installing the grinding part 33, the rotating component 31 drives the grinding component 32 to rotate, so that the grinding component 32 is opposite to the pushing mechanism 51. The barrel drive component 511 drives the connecting frame 512 and the barrel 513 to move towards the grinding component 32. The barrel 513 passes through the guide hole 523 and approaches the grinding component 32 until the distance between the barrel 513 and the grinding component 32 is the same as the thickness of a single grinding part 33. Then, the pushing drive component 514 pushes the grinding part 33 in the barrel 513 towards the grinding component 32, so that the bottommost grinding part 33 is removed from the barrel 513 and installed on the grinding component 32, thus completing the installation of the grinding part 33. After installation, the barrel drive component 511 drives the connecting frame 512 and the barrel 513 to reset, and the vertical drive mechanism 14 and the rotating component 31 operate independently, which can grind the workpiece 200.

[0033] In some embodiments, see Figure 2 and Figure 3 The workpiece positioning mechanism 20 includes a rotation drive assembly 21, a clamping assembly 22, and a positioning fixture 23. The rotation drive assembly 21 includes a rotation drive member 211 connected to the longitudinal drive mechanism 13 and a rotating frame 212 connected to the rotation drive member 211. The clamping assembly 22 includes a clamping drive member 221 connected to the rotating frame 212 and a clamping member 222 connected to the clamping drive member 221 and movably passing through the rotating frame 212. The positioning fixture 23 includes a carrier plate 231 and a cover plate 232. The carrier plate 231 and the cover plate 232 cooperate to clamp and position the workpiece 200. When the positioning fixture 23 is placed on the rotating frame 212, the clamping drive member 221 drives the clamping member 222 to clamp the positioning fixture 23.

[0034] The rotation drive 211 can be a rotary cylinder, etc., the structure of the rotating frame 212 is roughly U-shaped, the clamping drive 221 can be a rotary telescopic cylinder, and the structure of the clamping member 222 is roughly T-shaped. It can be understood that the interior of the carrier plate 231 and cover plate 232 of the positioning fixture 23, as well as the interior of the workpiece 200, are provided with through holes for the clamping member 222 to pass through. When the workpiece positioning mechanism 20 positions the workpiece 200, the positioning fixture 23 holding the workpiece 200 is placed on the rotating frame 212. At this time, the clamping member 222 passes through the carrier plate 231 and cover plate 232 of the positioning fixture 23. Then, the clamping drive 221 drives the clamping member 222 to rotate 90° and move towards the positioning fixture 23, thereby enabling the clamping member 222 to cooperate with the rotating frame 212 to clamp the positioning fixture 23, completing the positioning of the workpiece 200. When grinding the workpiece 200, the rotating drive 211 can drive the rotating component to rotate in the XY plane so that the side of the workpiece 200 can correspond to the grinding assembly 32, thereby grinding the side of the workpiece 200.

[0035] In some embodiments, see Figure 2 and Figure 3The workpiece positioning mechanism 20 also includes an adsorption component 24 connected to the rotating frame 212. The adsorption component 24 is used to adsorb the positioning fixture 23. The adsorption component 24 can be connected to an air extraction mechanism (not shown). When the positioning fixture 23 is placed on the rotating frame 212, the adsorption component 24 can adsorb the positioning fixture 23 to improve the stability of the positioning fixture 23, thereby improving the stability of the workpiece 200 when grinding and improving the grinding effect.

[0036] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The grinding device 30 also includes a flipping mechanism 34. The flipping mechanism 34 includes a flipping drive 341 connected to the bracket 52, a clamping drive 342 connected to the flipping drive 341, and two clamping plates 343 connected to the clamping drive 342. The vertical drive mechanism 14 drives the flipping mechanism 34 to move to the workpiece positioning mechanism 20 so that after the clamping assembly 22 releases the positioning fixture 23, the clamping drive 342 drives the two clamping plates 343 to clamp the positioning fixture 23. The flipping drive 341 is used to drive the clamping drive 342 and the clamping plates 343 to rotate around the X-axis, thereby flipping the positioning fixture 23.

[0037] The flipping drive 341 can be a rotary cylinder, the clamping drive 342 can be a double-headed telescopic cylinder, and the clamping plate 343 can be a plate-like structure. To improve the stability of the clamping drive 342 when driving the two clamping plates 343 to clamp the positioning fixture 23, in this embodiment, two clamping drive 342s can be provided. Both clamping drive 342s are connected to the two clamping plates 343 and synchronously drive the two clamping plates 343 to move closer or further apart to clamp or release the positioning fixture 23. It can be understood that, to further improve the stability of the clamping plates 343 when clamping the positioning fixture 23, a contoured structure corresponding to the positioning fixture 23 can be provided on the side where the two clamping plates 343 are close to each other, i.e., the side used to clamp the positioning fixture 23, thereby clamping the positioning fixture 23 more stably and preventing slippage when flipping the positioning fixture 23.

[0038] After the grinding assembly 32 drives the grinding piece 33 to grind the upper surface of the workpiece 200, the vertical drive mechanism 14 drives the bracket 52 to move towards the workpiece positioning mechanism 20 so that the two clamping plates 343 correspond to the positioning fixture 23. Then, the clamping drive 221 in the workpiece positioning mechanism 20 drives the clamping piece 222 to release the positioning fixture 23, and the clamping drive 342 drives the two clamping plates 343 to clamp the positioning fixture 23. Then, the vertical drive mechanism 14 drives the bracket 52 and the flipping mechanism 34 to move away from the workpiece positioning mechanism 20 along the Z-axis. The flipping drive 341 drives the clamping drive 342 to rotate 180°, which in turn drives the positioning fixture 23 to rotate 180°. Then, the vertical drive mechanism 14 drives the bracket 52, the flipping mechanism 34 and the positioning fixture 23 to move toward the workpiece positioning mechanism 20, and then places the positioning fixture 23 on the rotating frame 212. The clamping assembly 22 clamps the positioning fixture 23 again, thus completing the flipping of the workpiece 200. At this time, the lower surface of the workpiece 200 can be ground.

[0039] In some embodiments, see Figure 1 , Figure 6 and Figure 7 The grinding device 30 also includes a splitting mechanism 35, which includes a splitting drive 351 connected to the bracket 52 and a splitting gripper 352 connected to the splitting drive 351. The splitting drive 351 is used to drive the splitting gripper 352 to move toward the positioning fixture 23 on the workpiece positioning mechanism 20 so as to grab the cover plate 232 or the carrier plate 231 away from the workpiece 200 when the clamping assembly 22 releases the positioning fixture 23.

[0040] The splitting drive component 351 can be a telescopic cylinder, etc., and the splitting gripper 352 can be a robotic arm or a vacuum suction cup, etc. When it is necessary to change the workpiece 200, the clamping drive component 221 drives the clamping component 222 to release the positioning fixture 23. The vertical drive mechanism 14 drives the bracket 52 and the splitting mechanism 35 to move towards the positioning fixture 23. Then, the splitting drive component 351 drives the splitting gripper 352 to move towards the positioning fixture 23 to grab the cover plate 232 or the carrier plate 231. It can be understood that if the cover plate 232 is on top and the carrier plate 231 is on the bottom, the splitting gripper 352 grabs the cover plate 232. If the carrier plate 231 is on top and the cover plate 232 is on the bottom, the splitting gripper 352 grabs the carrier plate 231. Then, the splitting drive component 351 drives the splitting gripper 352 to move the cover plate 232 or the carrier plate 231 away from the workpiece 200. At this point, the polished workpiece 200 can be taken out and the workpiece 200 to be polished can be placed. Then, the disassembly drive 351 drives the disassembly gripper 352 to move toward the workpiece 200 so that the cover plate 232 or the carrier plate 231 can be placed on the workpiece 200. The clamping drive 221 drives the clamping member 222 to clamp the positioning fixture 23, so that the workpiece 200 can be polished.

[0041] In some embodiments, see Figure 1 The base 10 also includes a transverse drive mechanism 15, which is connected to a longitudinal drive mechanism 13. The longitudinal drive mechanism 13 is used to drive the transverse drive mechanism 15 to move along the Y-axis. The workpiece positioning mechanism 20, the scraper mechanism 40, and the adjustment component 70 are all connected to the transverse drive mechanism 15. The transverse drive mechanism 15 is used to drive the workpiece positioning mechanism 20, the scraper mechanism 40, and the adjustment component 70 to move along the X-axis.

[0042] The transverse drive mechanism 15 can be a linear module, etc. By setting the transverse drive mechanism 15, the workpiece positioning mechanism 20, the scraper mechanism 40 and the adjustment component 70 can be moved in the X-axis direction. That is, through the cooperation of the transverse drive mechanism 15 and the longitudinal drive mechanism 13, the workpiece positioning mechanism 20, the scraper mechanism 40 and the adjustment component 70 can be moved in the XY plane, which facilitates the grinding and processing of the workpiece 200.

[0043] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The scraper mechanism 40 includes a lifting drive 41, a connecting rod 42, and multiple scrapers 43. The lifting drive 41 is connected to the longitudinal drive mechanism 13 or the workpiece positioning mechanism 20. The connecting rod 42 is connected to the lifting drive 41. The multiple scrapers 43 are spaced apart on the connecting rod 42 along the X-axis. The lifting drive 41 is used to drive the connecting rod 42 to move along the Z-axis. Before disassembling the grinding part 33, the scrapers 43 are driven to rise and be positioned by the connecting rod 42. Then, the lateral drive mechanism 15 drives them to move along the Y-axis to scrape into the grinding part 33. During and after disassembly, the scrapers 43 are driven to fall by the connecting rod 42 to cooperate in disassembly and resetting.

[0044] The lifting drive component 41 can be a lifting cylinder, etc., to drive the connecting rod 42 to move along the Z-axis. The number of scrapers 43 can be five, ten, etc., and their positions correspond to the positions of the grinding parts 33 on the grinding assembly 32. When disassembling the grinding parts 33, the lifting drive component 41 drives multiple scrapers 43 to rise along the Z-axis via the connecting rod 42. Then, the longitudinal drive mechanism 13 drives the scraper mechanism 40 to move in the opposite direction of the Y-axis toward the grinding assembly 32, thereby causing the scrapers 43 to insert between the grinding parts 33 and the grinding assembly 32. The vertical drive mechanism 14 drives the rotating assembly 31 and the grinding assembly 32 to move along the Z-axis, causing the grinding assembly 32 to move away from the scrapers 43, and then the scrapers 43 scrape the grinding parts 33 off the grinding assembly 32. After disassembly, the lifting drive component 41 drives multiple scrapers 43 to descend in the opposite direction of the Z-axis via the connecting rod 42 to avoid the positioning fixture 23 and facilitate the grinding of the workpiece 200.

[0045] In some embodiments, see Figure 1 , Figure 2 and Figure 4The scraper 43 has a wedge-shaped structure, and its thickness in the Z-axis direction gradually increases away from the support frame 12. The scraper 43 has a locking hole 431 along the Y-axis direction, which connects to the cutting edge of the scraper 43. The scraper mechanism 40 also includes a scraper 44, which is connected to the scraper 43 and forms a receiving space between the scraper 43 and the scraper 43 to accommodate the grinding part 33. The wedge-shaped structure of the scraper 43 facilitates insertion between the grinding part 33 and the grinding assembly 32, and helps to separate the grinding part 33 and the grinding assembly 32. The locking hole 431 on the scraper 43 is used to avoid obstructing a protruding connecting structure between the grinding assembly 32 and the grinding part 33. By setting the scraper 44, when the scraper 43 moves between the grinding part 33 and the grinding assembly 32, the scraper 44 can abut against the grinding part 33 to guide the position of the grinding part 33, so that the scraper 43 can be inserted between the grinding part 33 and the grinding assembly 32.

[0046] In one embodiment, a waste box (not shown) is provided below the scraper 43 to facilitate the collection of the disassembled grinding parts 33. A slope may also be provided below the scraper 43 to allow the disassembled grinding parts 33 to slide along the slope away from the bottom of the scraper 43, thereby preventing the grinding parts 33 from accumulating and affecting the subsequent disassembly of the grinding parts 33.

[0047] In some embodiments, see Figure 1 and Figure 4 The rotating assembly 31 includes a rotating drive member 311 connected to the vertical drive mechanism 14 and a grinding seat 312 connected to the rotating drive member 311. The rotating drive member 311 is used to drive the grinding seat 312 to rotate around the X-axis. The grinding seat 312 includes multiple cross surfaces 3121. The grinding assembly 32 is disposed in the grinding seat 312 and is provided with a connector 321 protruding from the cross surface 3121. The connector 321 is used to connect the grinding component 33.

[0048] The rotary drive 311 can be a rotary cylinder, etc., and the grinding base 312 can be a cuboid structure. The driving unit of the grinding assembly 32, which is disposed in the grinding base 312, can be a double-headed rotary cylinder, etc. In this way, the two ends of the double-headed rotary cylinder in each grinding assembly 32 extend out of the two opposite cross surfaces 3121 of the grinding base 312, and both ends are provided with connectors 321. Thus, each grinding assembly 32 is provided with two connectors 321 to connect two grinding parts 33. It can be understood that the grinding assemblies 32 connected to the same cross surface 3121 are spaced apart along the X-axis direction, and the spacing is the same as the distance between adjacent scrapers 43. The grinding assemblies 32 connected on adjacent cross surfaces 3121 are staggered so that the grinding assemblies 32 in the grinding base 312 avoid each other.

[0049] In one embodiment, ten grinding components 32 are provided, each protruding from two opposing cross surfaces 3121 and having two connectors 321. Five grinding components 32 are connected to the same cross surface 3121, and the other five grinding components 32 are connected to other cross surfaces 3121, so that each cross surface 3121 has five connectors 321, and the distance between any two adjacent connectors 321 on each cross surface 3121 is the same. Five workpiece positioning mechanisms 20 are provided, and the distance between any two adjacent workpiece positioning mechanisms 20 is the same, and this distance is the same as the distance between any two adjacent connectors 321. Five scrapers 43 are provided, and the distance between any two adjacent scrapers 43 is the same as the distance between any two adjacent connectors 321. The changing device 50 has ten material cylinders 513, five of which correspond to the connectors 321 of the five grinding components 32 located on the same cross-section 3121, and the other five correspond to the connectors 321 of the other five grinding components 32. During grinding, the vertical drive mechanism 14 drives the grinding device 30 to move downward in the opposite direction of the Z-axis, and the longitudinal drive mechanism 13 drives the workpiece positioning mechanism 20 to move in the opposite direction of the Y-axis, so that the workpiece 200 corresponds to the grinding element 33 connected to the five grinding components 32 on the same cross-section 3121, thereby grinding the workpiece 200. When it is necessary to use the grinding elements 33 connected to the other five grinding components 32 for grinding, the workpiece positioning mechanism 20 is moved in the X-axis direction by the transverse drive mechanism 15 so that the workpiece 200 corresponds to the grinding element 33 connected to the other five grinding components 32.

[0050] In some embodiments, see Figure 1 and Figure 8 The grinding equipment 100 also includes a circulation mechanism 80, which comprises a water tank 81, a water pump 82, and a nozzle 83. The water tank 81 is located near the base 11 and contains a filter assembly 84 for filtering the liquid. The water pump 82 is connected to the water tank 81, and the nozzle 83 is connected to the water pump 82 and is positioned towards the grinding workpiece 33 on the grinding assembly 32. The nozzle 83 sprays liquid onto the grinding workpiece 33. In this way, liquid can be sprayed onto the workpiece 200 and the grinding workpiece 33 during grinding to cool them down and prevent high temperatures from damaging the surface of the workpiece 200. The filter assembly 84 filters the liquid, preventing impurities from entering the water pump 82 and being sprayed onto the workpiece 200 and the grinding workpiece 33, thus avoiding damage to the workpiece 200. The recycling of the liquid also helps improve resource utilization efficiency and reduce environmental impact.

[0051] The working process of the grinding equipment 100 provided in this embodiment is roughly as follows:

[0052] Installing workpiece 200: The vertical drive mechanism 14 drives the bracket 52 to move in the opposite direction of the Z-axis, while the longitudinal drive mechanism 13 drives the workpiece positioning mechanism 20 to move in the opposite direction of the Y-axis, thereby aligning the splitting mechanism 35 on the bracket 52 with the workpiece positioning mechanism 20. Then, the clamping drive 221 in the workpiece positioning mechanism 20 drives the clamping member 222 away from the positioning fixture 23 and rotates it, so that the clamping member 222 releases the positioning fixture 23. The splitting drive 351 in the splitting mechanism 35 drives the splitting gripper 352 to grasp the cover plate 232 and move the cover plate 232 away from the carrier plate 231. At this time, the cover plate 232 separates from the carrier plate 231, and the workpiece 200 can be placed on the carrier plate 231. After the workpiece 200 is placed, the splitting drive 351 drives the splitting gripper 352 to place the cover plate 232 on the workpiece 200. The splitting gripper 352 is reset, and the clamping drive 221 drives the clamping component 222 to clamp the positioning fixture 23. The adsorption component 24 adsorbs the positioning fixture 23, thus completing the installation of the workpiece 200.

[0053] Grinding workpiece 200: When grinding the side of workpiece 200, the rotary drive 311 in the grinding device 30 drives the grinding seat 312 to rotate, so that one of the cross surfaces 3121 is in a vertical position and faces the workpiece positioning mechanism 20. The vertical drive mechanism 14 drives the grinding device 30 to move in the Z-axis direction, so that the grinding part 33 on the cross surface 3121 facing the workpiece positioning mechanism 20 is on the same horizontal plane as the workpiece 200. Then the longitudinal drive mechanism 13 drives the workpiece positioning mechanism 20 and the workpiece 200 to move in the Y-axis direction, so that the side of the workpiece 200 abuts against the grinding part 33. Then the grinding assembly 32 drives the grinding part 33 and the workpiece 200 to grind the side of the workpiece 200. When other sides need to be ground, the rotary drive 211 drives the rotating frame 212 to rotate in the XY plane in advance, so that the side to be ground corresponds to the grinding part 33. Then the longitudinal movement mechanism moves the workpiece 200 to abut against the grinding part 33 for grinding. When grinding the upper surface of workpiece 200, the rotary drive 311 drives the grinding seat 312 to rotate, so that one of the cross surfaces 3121 is on a horizontal plane and the grinding element 33 on the cross surface 3121 is positioned downwards. Then, the longitudinal moving mechanism drives the workpiece positioning mechanism 20 and the workpiece 200 to move below the grinding element 33. The vertical drive mechanism 14 drives the grinding device 30 to move downwards, so that the grinding element 33 abuts against the upper surface of the workpiece 200, and grinding can then be performed. When grinding the lower surface of workpiece 200, the positioning fixture 23 is flipped by the flipping mechanism 34, and then moved again to below the grinding element 33 for grinding. During the grinding process, the circulation mechanism 80 sprays liquid onto the workpiece 200 and the grinding element 33 for cooling.

[0054] Replace workpiece 200: Repeat the above process of installing workpiece 200. After the cover plate 232 is separated from the carrier plate 231, add the process of taking the polished workpiece 200 out of the positioning fixture 23.

[0055] Replacing the grinding part 33: The lifting drive 41 in the scraper mechanism 40 drives multiple scrapers 43 to rise along the Z-axis direction via the connecting rod 42. The vertical drive mechanism 14 drives the grinding device 30 to move in the Z-axis direction. The grinding part 33 to be replaced in the grinding device 30 is located on the horizontal plane and facing downwards. Then, the longitudinal drive mechanism 13 drives the scraper mechanism 40 to move towards the grinding assembly 32 in the opposite direction of the Y-axis, thereby causing the scraper 43 to insert between the grinding part 33 and the connector 321. The vertical drive mechanism 14 drives the rotating assembly 31 and the grinding assembly 32 to move along the Z-axis direction, causing the grinding assembly 32 to move away from the scraper 43, and then the scraper 43 scrapes the grinding part 33 off the grinding assembly 32. After disassembly, the lifting drive 41 drives multiple scrapers 43 to descend in the opposite direction of the Z-axis via the connecting rod 42.

[0056] Then, the rotary drive 311 drives the grinding base 312 to rotate so that the connector 321 of the grinding part 33 to be installed faces the barrel 513. The barrel drive 511 drives the connecting frame 512 and the barrel 513 to move toward the connector 321 until the distance between the barrel 513 and the connector 321 is the same as the thickness of a single grinding part 33. Then, the push drive 514 pushes the grinding part 33 in the barrel 513 toward the connector 321, so that the bottommost grinding part 33 is removed from the barrel 513 and installed on the connector 321, thus completing the installation of the grinding part 33.

[0057] After installation, the rotary drive 311 drives the grinding component 33 to rotate around the Y-axis, aligning the grinding component 33 with the sensor 62 in the alignment mechanism 60. The vertical drive mechanism 14 moves the grinding device 30 towards the alignment mechanism 60, allowing the sensor 62 to detect the thickness of each grinding component 33, i.e., the distance between the side of the grinding component 33 used to grind the workpiece 200 and the corresponding cross-sectional surface 3121. Based on the distance between the side of the different grinding components 33 used to grind the workpiece 200 and the corresponding cross-sectional surface 3121, the adjustment component 70 adjusts the position of the corresponding workpiece positioning mechanism 20 on the YZ plane, adjusting the position of the workpiece 200 according to the thickness information of each grinding component 33, thereby ensuring that the grinding degree of each grinding component 33 on the workpiece 200 is consistent during grinding. It is understood that when the grinding component 33 is used for a period of time but does not need to be replaced, the grinding component 33 can also be detected, and the position of the workpiece 200 can be adjusted according to the new thickness information.
