[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] Example 1: See Figure 1 and 2 A metal electrode grinding machine, comprising: Base 1; The milling mechanism 2 is located at the middle of the base 1 along its length. The flipping loading and unloading mechanism 3 is located on one side of the base 1 along its length and has a flipping frame 44 for supporting the metal electrode plate 55. Clamping members are provided on both sides of the flipping frame 44 in the width direction, and are arranged at intervals along the length direction of the flipping frame 44; A positioning element is provided on the side of the flipping frame 44 near the flipping axis, and is used to extend and abut against the end of the flipping frame 44 away from the flipping axis when the flipping frame 44 is rotated to the vertical direction.

[0021] Specifically, the metal electrode 55 in this application is at least one of a copper electrode, a nickel electrode, or a cobalt electrode. The base 1 of the metal electrode grinding machine of this application has an overall rectangular structure, which has a length direction and a width direction; the milling mechanism 2 is located in the middle of the base 1 along the length direction and is supported by the base 1. The milling mechanism 2 is used to grind the metal electrode 55. Its grinding actuator has the freedom to move in the vertical and horizontal directions, and can grind the metal electrode 55 in the length direction and the width direction respectively, while controlling the grinding depth.

[0022] The milling mechanism 2 and the tilting loading / unloading mechanism 3 are connected by a connecting rod 58 to ensure the relative positional accuracy between them and improve the stability of the overall structure. The tilting loading / unloading mechanism 3 is located on one side of the base 1 along its length, with its tilting axis close to the milling mechanism 2. The tilting frame 44 of the tilting loading / unloading mechanism 3 is used to carry the metal electrode plate 55. It has a horizontal loading station and a vertical working station and can rotate between the horizontal and vertical positions around the tilting axis. When the tilting frame 44 is tilted to the horizontal loading station, it is parallel to the base 1 and is in a low position for easy loading. When the tilting frame 44 drives the metal electrode plate 55 to the vertical working station, the end of the tilting frame 44 away from the tilting axis is close to the positioning component, which facilitates the positioning component to fix the tilting frame 44. After a single grinding operation is completed, the tilting frame 44 is tilted back to the horizontal loading station, and this cycle is repeated to achieve continuous production.

[0023] Clamping members are located on both sides of the flipping frame 44 in the width direction, and multiple clamping members are arranged at intervals along the length direction of the flipping frame 44. When the metal electrode plate 55 is placed on the flipping frame 44, the clamping members on both sides clamp and fix the electrode plate 55 in the width direction, preventing the electrode plate 55 from shifting during subsequent flipping and processing. Since the clamping members are arranged at intervals along the length direction of the flipping frame 44, the two sides of the electrode plate 55 are constrained along its entire length, avoiding warping or local deformation of the electrode plate 55 caused by single-point clamping or local clamping. During the flipping of the electrode plate 55 with the flipping frame 44 and subsequent grinding processing, this clamping structure can limit the in-plane displacement of the electrode plate 55, preventing the electrode plate 55 from slipping or vibrating under the action of milling force. After grinding, the clamping members are released to both sides, releasing the constraint on the electrode plate 55, making it easier to unload.

[0024] The positioning element is located on the side of the tilting frame 44 near the tilting axis and has a telescopic function. When the tilting frame 44 rotates around the tilting axis to the vertical direction, the positioning element extends and abuts against the end of the tilting frame 44 away from the tilting axis, thereby locking the tilting frame 44 in the vertical working position, making the tilting frame 44 completely positioned, preventing shaking during the grinding process, and improving the grinding accuracy.

[0025] In operation, the metal electrode plate 55 is first placed on the flipping frame 44. Multiple clamping members, located on both sides of the flipping frame 44 in the width direction and spaced apart along its length, move synchronously to evenly clamp the electrode plate 55. Then, the flipping frame 44 rotates the electrode plate 55 from a horizontal loading position to a vertical working position around the flipping axis. During this process, the electrode plate 55 remains relatively fixed to the flipping frame 44 due to being clamped at multiple points. After the flipping frame 44 is in position, the positioning member extends and abuts against the end of the flipping frame 44 away from the flipping axis, providing a stable constraint to the flipping frame 44 in the vertical direction. At this time, the milling mechanism 2 starts to grind the electrode plate 55 fixed on the flipping frame 44. Throughout the entire processing, because the electrode plate 55 is firmly fixed to the flipping frame 44 by the clamping members and supported by the flipping frame 44, and the flipping frame 44 is locked in a vertical position by the positioning member, vibration or displacement of the metal electrode plate 55 during high-speed grinding is suppressed. After grinding, the positioning part retracts, the flipping frame 44 drives the electrode plate 55 to rotate to the horizontal loading position, the clamping part is released, and the processed electrode plate 55 can be removed.

[0026] Traditional metal electrode 55 grinding equipment mostly adopts a horizontal processing method, and its clamping mechanism mainly relies on vacuum adsorption or edge pressure plate. Due to the extremely thin thickness of the metal electrode 55, traditional metal electrode 55 grinding equipment cannot provide sufficient in-plane constraint rigidity. Therefore, the electrode 55 is prone to vibration or displacement during high-speed grinding, resulting in uneven grinding depth and easy damage to the flow channel structure. This application places the metal electrode plate 55 on the flipping frame 44 and utilizes its tilting posture adjustment to a vertical working position. Combined with multiple clamping components arranged at intervals along the length of the flipping frame 44 on both sides of its width, the electrode plate 55 is uniformly clamped at multiple points, limiting in-plane displacement of the electrode plate 55 and suppressing warping deformation. At the same time, a positioning component located on the side of the flipping frame 44 near the flipping axis extends and abuts against the end of the flipping frame 44 away from the axis when the flipping frame 44 is rotated to a vertical position, locking the flipping frame 44 in place. This improves the constraint rigidity and positioning stability of the overall structure, suppresses vibration or displacement of the electrode plate 55 during high-speed grinding, thereby improving the uniformity of grinding depth and reducing the risk of damage to the flow channel structure.

[0027] Example 2: See Figures 1 to 7Based on the above embodiments, optionally, the milling mechanism 2 includes: a gantry assembly 7, the gantry assembly 7 including a first gantry 12, the first gantry 12 having first guide rails 16 on both sides along its length direction, and the first guide rails 16 extending along the height direction of the first gantry 12, a crossbeam assembly 8 slidably connected on the first guide rails 16, the crossbeam assembly 8 being connected to a lifting drive assembly 10 via a synchronous chain 38, the lifting drive assembly 10 being installed at the end of the first gantry 12 away from the base 1, and a counterweight 11 being provided at one end of the synchronous chain 38; The height direction of the first gantry 12 is parallel to the vertical direction.

[0028] Specifically, the first gantry 12 is fixedly installed on the base 1, and its overall structure is gantry-shaped. The first gantry 12 has a length direction, a width direction, and a height direction, with its height direction being parallel to the vertical direction. The first guide rail 16 is fixed to the first gantry 12 and extends along the height direction of the first gantry 12, that is, it extends along the vertical direction. The two first guide rails 16 are arranged in parallel and opposite directions, together forming the lifting guide path of the crossbeam assembly 8.

[0029] The crossbeam assembly 8 is slidably connected to the first guide rail 16 via sliders. Furthermore, sliders are fixed to both ends of the crossbeam assembly 8, and each slider slides into contact with the corresponding side of the first guide rail 16. The crossbeam assembly 8 can move vertically up and down along the first guide rail 16, thereby raising and lowering the grinding actuator mounted on the crossbeam assembly 8 to adjust the grinding height. A lifting drive assembly 10 is installed at the end of the first gantry 12 furthest from the base 1 (i.e., the top of the first gantry 12). The lifting drive assembly 10 is driven by a synchronous chain 38, and by driving the synchronous chain 38, it raises or lowers the crossbeam assembly 8 along the first guide rail 16. One end of the synchronous chain 38 is connected to the crossbeam assembly 8, and the other end is connected to a counterweight 11. The counterweight 11 is suspended on one side of the first gantry 12, and its weight is approximately equal to the total weight of the crossbeam assembly 8 and the grinding actuator mounted on it. The counterweight 11 is used to balance the weight of the crossbeam assembly 8 and related components mounted on it. When the lifting drive assembly 10 drives the crossbeam assembly 8 to rise via the synchronous chain 38, the counterweight 11 descends synchronously under the drive of the chain; conversely, when the crossbeam assembly 8 descends, the counterweight 11 rises synchronously. Through this reverse motion, the counterweight 11 offsets the weight of the crossbeam assembly 8 and the components it supports, thereby reducing the drive load and making the lifting motion smoother.

[0030] During operation, according to the size and processing requirements of the electrode plate 55 to be polished, the lifting drive assembly 10 drives the crossbeam assembly 8 to rise and fall along the first guide rail 16. The polishing actuator installed on the crossbeam assembly 8 rises and falls synchronously with the crossbeam assembly 8, so that it rises and falls to a suitable height or target height, and polishes the electrode plate 55 fixed on the flipping frame 44.

[0031] Optionally, the crossbeam assembly 8 includes: a crossbeam 15, a second guide rail 17 provided along its length, a new power head 9 slidably connected to the second guide rail 17 via a first slider 32, and a transverse drive motor 25 being driven by a transverse belt 24; The length direction of the crossbeam 15 is perpendicular to the height direction of the first gantry 12.

[0032] Specifically, the length direction of the crossbeam 15 is perpendicular to the height direction of the first gantry 12, meaning the crossbeam 15 is horizontally arranged. The new power head 9 is slidably connected to the second guide rail 17 via the first slider 32. Further, the second guide rail 17 is provided along the length direction of the crossbeam 15. The first slider 32 is fixed to the new power head 9, and the first slider 32 and the second guide rail 17 are in sliding engagement, allowing the new power head 9 to reciprocate along the second guide rail 17 in the length direction of the crossbeam 15 (i.e., lateral movement). The lateral movement drive motor 25 is mounted on the crossbeam 15, and its output end is connected to the pulley 42 system. The lateral movement belt 24 is connected to the new power head 9. When the lateral movement drive motor 25 starts, the lateral movement belt 24 drives the new power head 9 to reciprocate along the second guide rail 17. That is, when the motor rotates forward, the belt moves in one direction, driving the new power head 9 to move to one side along the guide rail; when the motor rotates in reverse, the belt moves in the opposite direction, driving the new power head 9 to move to the other side, thereby realizing the lateral movement of the new power head 9 in the horizontal direction.

[0033] During operation, the crossbeam assembly 8 rises and falls along the height of the first gantry 12, driving the new power head 9 to move along the height of the electrode plate 55. The transverse drive motor 25 drives the new power head 9 to move horizontally along the length of the crossbeam 15 via the drive pulley 42 and the transverse belt 24, enabling the grinding actuator mounted on the new power head 9 to cover the transverse area of ​​the electrode plate 55. Through the above structure, the new power head 9 rises and falls vertically with the crossbeam assembly 8 and moves horizontally along the second guide rail 17, thereby achieving grinding of different positions on the surface of the electrode plate 55.

[0034] Example 3: See Figures 1 to 7 Based on the above embodiments, optionally, the new power head 9 includes: a transverse support 20, a third guide rail 18 is provided on the side of the support close to the base 1, a second slider 33 is slidably mounted on the third guide rail 18, a sliding plate 23 is provided on the side of the second slider 33 away from the third guide rail 18, a milling cutter assembly 22 is mounted on the side of the sliding plate 23 away from the second slider 33, and a depth feed motor 26 is connected to the sliding plate 23. The sliding plate 23 driven by the depth feed motor 26 moves in a direction perpendicular to the moving direction of the new power head 9 driven by the transverse drive motor 25.

[0035] Specifically, the sliding plate 23, the second slider 33, the third guide rail 18, and the depth feed motor 26 constitute the slide plate assembly 21. The transverse support 20 is slidably engaged with the second guide rail 17 via the first slider 32, and the transverse support 20 is connected to the transverse belt 24. The third guide rail 18 is provided on the side of the transverse support 20 near the base 1. The third guide rail 18 extends perpendicular to the length of the crossbeam 15, that is, it extends along the normal direction of the pole plate 55. The sliding plate 23 is slidably connected to the third guide rail 18 via the second slider 33.

[0036] Furthermore, the second slider 33 is slidably engaged with the third guide rail 18, and the sliding plate 23 is fixedly installed on the side of the second slider 33 away from the third guide rail 18, allowing the sliding plate 23 to move linearly along the third guide rail 18. A milling cutter assembly 22 is mounted on the side of the sliding plate 23 away from the second slider 33. The milling cutter assembly 22 is used for grinding the metal electrode plate 55. The depth feed motor 26 is a linear drive motor, which is connected to the sliding plate 23. When the depth feed motor 26 is started, it drives the sliding plate 23 to move along the third guide rail 18, thereby causing the milling cutter assembly 22 to perform a normal feed motion relative to the electrode plate 55 to control the grinding depth. The direction of movement of the sliding plate 23 driven by the depth feed motor 26 is perpendicular to the direction of movement of the new power head 9 driven by the traverse drive motor 25.

[0037] Furthermore, the new power head 9 moves along the length of the crossbeam 15 under the drive of the transverse drive motor 25, achieving sweeping along the width of the electrode plate 55; the sliding plate 23 moves along the third guide rail 18 under the drive of the depth feed motor 26, achieving feeding along the normal direction of the electrode plate 55. The two movements are orthogonal, together forming a multi-dimensional motion system.

[0038] During operation, the transverse drive motor 25 drives the new power head 9 to move along the length of the crossbeam 15, causing the milling cutter assembly 22 to cover the machining area of ​​the electrode plate 55 in the width direction. Simultaneously, the depth feed motor 26 drives the sliding plate 23 to move along the third guide rail 18, causing the milling cutter assembly 22 to cut into the surface of the electrode plate 55 at a preset depth. Through the coordinated movement of the two, precise grinding of the surface of the electrode plate 55 is achieved.

[0039] Optionally, the milling cutter assembly 22 includes a milling cutter 29, which is connected to a milling cutter 29 drive motor 27 via a spindle sleeve 30, and the spindle sleeve 30 is connected to a flange sleeve 31, which is installed on the side of the sliding plate 23 away from the second slider 33 via the flange sleeve 31.

[0040] Specifically, the milling cutter 29 is mounted on one end of the spindle, and the other end of the spindle is connected to the output end of the milling cutter 29 drive motor 27. When the milling cutter 29 drive motor 27 starts, its output end drives the spindle to rotate, and the spindle drives the milling cutter 29 to rotate together, thereby realizing high-speed rotary cutting by the milling cutter 29. The spindle sleeve 30 is sleeved on the outside of the spindle and rotates with the spindle through bearings. The spindle sleeve 30 is used to support the spindle and provide a mounting structure for the milling cutter assembly 22. A flange sleeve 31 is connected to the outside of the spindle sleeve 30, and the flange sleeve 31 is fixedly connected to the spindle sleeve 30. A flange is provided at the end of the flange sleeve 31 away from the spindle sleeve 30. This flange is used to mount the entire milling cutter assembly 22 onto the sliding plate 23.

[0041] During operation, the sliding plate 23 moves along the third guide rail 18 under the drive of the depth feed motor 26, causing the milling cutter assembly 22 to perform a feed motion and control the grinding depth. The milling cutter 29 drive motor 27 drives the spindle to rotate, causing the milling cutter 29 to rotate at high speed and cut and grind the surface of the electrode plate 55. The flange sleeve 31 and the spindle sleeve 30 play a connecting and supporting role in this process, reliably fixing the milling cutter assembly 22 on the sliding plate 23 and ensuring the stability of the milling cutter 29 during high-speed rotation.

[0042] Example 4: See Figures 1 to 7 Based on the above embodiments, optionally, the lifting drive assembly 10 includes: a pulley shaft 35 and a sprocket shaft 36, which are mounted parallel to each other on the end of the first gantry 12 away from the base 1 via a first bearing seat 39; each of the two axial ends of the pulley shaft 35 is provided with a set of transmission wheels, each set of transmission wheels includes a pulley 42 and a sprocket 37 coaxially arranged, and a lifting drive motor 40 is drivenly connected to one axial end of the pulley shaft 35. A pulley 42 is also installed on the side of the first gantry 12, and a lifting belt 41 is wound around the pulley 42. A retaining edge 43 is provided on the outer side of the pulley 42; the two axial ends of the sprocket shaft 36 are respectively fitted with the same sprocket 37, and a synchronous chain 38 is wound around the sprocket 37.

[0043] Specifically, the pulley shaft 35 and the sprocket shaft 36 are rotatably mounted on the top of the first gantry 12, with their axes parallel to each other. A set of transmission wheels is provided at each axial end of the pulley shaft 35. Each set of transmission wheels includes a pulley 42 and a sprocket 37, with the pulley 42 and sprocket 37 coaxially mounted on the pulley shaft 35. That is, one end of the pulley shaft 35 is fitted with both the pulley 42 and the sprocket 37, and the other end is also fitted with both. A lifting drive motor 40 is driven to one axial end of the pulley shaft 35. A pulley 42 is also mounted on the side of the first gantry 12, and a lifting belt 41 is wound around the two pulleys 42 on the same side, forming a belt drive circuit. To prevent the lifting belt 41 from disengaging during operation, a retaining edge 43 is provided on the outer side of the pulley 42. The flange 43 can be a wheel rim or an annular protrusion, arranged on both sides of the pulley body along the axial direction of the pulley 42. It can prevent the lifting belt 41 from axially slipping or dislodging during high-speed operation, ensuring the reliability of the transmission. The two ends of the sprocket shaft 36 are respectively fitted with sprockets 37 identical to those on the pulley shaft 35, and the two sprockets 37 are arranged symmetrically. A synchronous chain 38 is wound around the sprockets 37 to form a chain drive circuit.

[0044] During operation, the lifting drive motor 40 drives the pulley shaft 35 to rotate, which in turn drives the pulleys 42 and sprockets 37 at both ends of the pulley shaft 35 to rotate synchronously. The synchronous chain 38 drives the sprockets 37 at both ends of the sprocket shaft 36 to rotate, while the synchronous chain 38 drives the crossbeam assembly 8 to move up and down along the first guide rail 16.

[0045] Example 5: See Figures 1 to 7 Based on the above embodiments, optionally, the flipping loading and unloading mechanism 3 includes: a second gantry 13, one end of which near the base 1 is equipped with a flipping shaft 50 via a second bearing seat 52, the flipping shaft 50 being rotatably connected to one end of the flipping frame 44 in the length direction, and flipping cylinders 45 being provided on both sides of the flipping frame 44 in the width direction, the cylinder body of the flipping cylinder 45 being mounted on the base 1; The positioning component includes: a support beam 46 mounted on the second gantry 13 along its length, with positioning cylinders 47 at both ends of the support beam 46 along its length, the telescopic axis of the positioning cylinders 47 facing the flipping shaft 50; and positioning plates 48 on both sides of the flipping frame 44 along its width, with the positioning plates 48 extending along the length of the flipping frame 44. The clamping component includes: a rotating clamping arm 49 located on the outside of the positioning plate 48, one end of which is connected to a clamping cylinder 14, the cylinder body of which is mounted on the side of the flipping frame 44 near the base 1; and two centering cylinders 51 are provided opposite to the end of the flipping frame 44 away from the flipping shaft 50.

[0046] Specifically, the second gantry 13 is fixedly installed on the base 1. Its end closest to the base 1 (i.e., the lower end) is connected to a tilting shaft 50 via a second bearing seat 52. The tilting shaft 50 is rotatably connected to one end of the tilting frame 44 along its length, meaning the tilting frame 44 can rotate relative to the second gantry 13 around the tilting shaft 50. The tilting frame 44 carries the metal electrode plate 55. Tilting cylinders 45 are arranged on both sides of its width. The cylinder bodies of the tilting cylinders 45 are mounted on the base 1, and the piston rods of the tilting cylinders 45 are connected to the sides of the tilting frame 44. When the tilting cylinders 45 are activated, the piston rods push the tilting frame 44 to rotate around the tilting shaft 50, switching the tilting frame 44 between a horizontal loading position and a vertical operating position.

[0047] The positioning element is used to fix the tilting frame 44 when it is tilted to the vertical working position. The support beam 46 of the positioning element is fixed to the second gantry 13. Positioning cylinders 47 are respectively installed at both ends of the support beam 46 in the length direction, and positioning plates 48 are provided on both sides of the tilting frame 44 in the width direction. Thus, when the tilting frame 44 is rotated to the vertical direction, the positioning cylinders 47 rotate and extend, pressing against the ends of the positioning plates 48 away from the tilting shaft 50, thereby rigidly locking the tilting frame 44 in the vertical working position.

[0048] The clamping member is used to clamp and fix the electrode plate 55 onto the flipping frame 44. One end of the rotating clamping arm 49 of the clamping member is connected to the clamping cylinder 14, and the cylinder body of the clamping cylinder 14 is installed on the side of the flipping frame 44 near the base 1 (i.e., the lower side of the flipping frame 44). Thus, when the clamping cylinder 14 is activated, it can drive the rotating clamping arm 49 to clamp or release the electrode plate 55. Since the rotating clamping arms 49 are located outside the positioning plate 48 and multiple arms are arranged at intervals along the length of the flipping frame 44, the electrode plate 55 can be clamped at multiple points symmetrically from both sides in the width direction.

[0049] Two centering cylinders 51 are provided opposite to the end of the tilting frame 44 away from the tilting shaft 50 (i.e., the free end). The cylinder body of the centering cylinder 51 is mounted on the tilting frame 44. The centering cylinder 51 is used to push the electrode plate 55 when it is placed, so that it is fixed in the preset position in the vertical direction, ensuring the consistency of the position each time it is loaded.

[0050] Both the positioning cylinder 47 and the clamping cylinder 14 are rotary telescopic cylinders.

[0051] Example 6: See Figures 1 to 7Based on the above embodiments, optionally, a scanning component 4 is also included. The scanning component 4 includes: a feeding drive frame 53, which is located on the side of the base 1 away from the flipping loading and unloading mechanism 3. The end of the feeding drive frame 53 away from the base 1 is provided with a fourth guide rail 19, and the fourth guide rail 19 extends along the length direction of the feeding drive frame 53. A third slider 34 is slidably connected to the fourth guide rail 19. A lead screw 54 is threaded through the third slider 34. A vision device 56 is installed on the side of the third slider 34 away from the fourth guide rail 19. A lead screw drive motor 28 is axially connected to one end of the lead screw 54. A protective cover 57 is provided at the end of the feeding drive frame 53 near the lead screw drive motor 28.

[0052] Specifically, the feeding drive frame 53 is fixedly mounted on the base 1, located at the end of the base 1 away from the tilting loading / unloading mechanism 3 along its length. A fourth guide rail 19 is provided at the end of the feeding drive frame 53 away from the base 1 (i.e., the upper end), extending along the length of the feeding drive frame 53. The length of the feeding drive frame 53 is parallel to the length of the base 1, ensuring that the extension direction of the fourth guide rail 19 is consistent with the length of the base 1. A third slider 34 is slidably connected to the fourth guide rail 19. The third slider 34 slides along the fourth guide rail 19 and can reciprocate along it. A lead screw 54 is threaded onto the third slider 34, meaning the internal thread of the third slider 34 meshes with the external thread of the lead screw 54. The lead screw 54 is rotatably mounted on the feeding drive frame 53, its axis parallel to the extension direction of the fourth guide rail 19. A vision device 56 is installed on the side of the third slider 34 away from the fourth guide rail 19 for scanning and identifying the electrode plate 55. It can be a 3D camera, a laser profilometer, or a structured light scanner, etc., to obtain the three-dimensional shape information of the electrode plate 55.

[0053] One axial end of the lead screw 54 is connected to a lead screw drive motor 28, which is fixed to the side of the feeding drive frame 53. When the lead screw drive motor 28 starts, the lead screw 54 rotates, driving the third slider 34 to move along the fourth guide rail 19 via a thread, thereby moving the vision device 56 along the length of the feeding drive frame 53 to scan the electrode plate 55. A protective cover 57 is provided at the end of the feeding drive frame 53 near the lead screw drive motor 28 to protect the vision device 56 when it moves to that end, preventing metal particles generated during grinding from splashing onto the vision device 56 and causing contamination or damage, thus extending the service life of the vision device 56.

[0054] During operation, the electrode plate 55 is fixed and rotated to a vertical working position by the flipping loading and unloading mechanism 3. The lead screw drive motor 28 drives the lead screw 54 to rotate, and the third slider 34 drives the vision device 56 to move along the fourth guide rail 19 from one end to the other to scan the entire surface of the electrode plate 55 and obtain its three-dimensional shape information. After scanning, the vision device 56 returns to the end near the protective cover 57, which shields it to prevent particles generated during subsequent grinding from contaminating it.

[0055] Example 7: See Figure 1 and 2 Based on the above embodiments, optionally, a chip collection belt 5 is provided on the side of the base 1 near the milling mechanism 2, the flipping loading and unloading mechanism 3 and the scanning component 4, and the conveying direction of the chip collection belt 5 is parallel to the length direction of the base 1.

[0056] Specifically, the chip collection conveyor belt 5 is laid on the upper surface of the base 1, positioned so that the milling mechanism 2, the tilting and unloading mechanism 3, and the scanning component 4 are all directly above the chip collection conveyor belt 5, in order to collect metal chips, particles, and dust generated during the grinding process. The conveying direction of the chip collection conveyor belt 5 is parallel to the length direction of the base 1, that is, the conveyor belt of the chip collection conveyor belt 5 extends along the length direction of the base 1 and moves towards one end of the base 1 or the external collection container.

[0057] During operation, the milling mechanism 2 grinds the electrode plate 55, and the resulting metal particles and shavings fall under gravity onto the conveyor belt of the shavings collection conveyor 5. After the shavings collection conveyor 5 starts, the conveyor belt moves along the length of the base 1, transporting the shavings to one end of the base 1 for centralized cleaning or recycling. By setting up the shavings collection conveyor 5, the shavings generated during grinding can be collected in a timely and efficient manner, preventing shavings from accumulating in the working area, improving the working environment, reducing contamination of precision parts, reducing the frequency of manual cleaning, and improving production efficiency.

[0058] Optionally, the base 1, the milling mechanism 2 and the scanning component 4 are covered with a cover 6, which is made of transparent material.

[0059] Specifically, the cover 6 adopts a split shell structure, which is positioned to avoid the working paths of the tilting loading / unloading mechanism 3 and the chip collection conveyor 5. The cover 6 is made of transparent material, such as polycarbonate (PC), plexiglass (PMMA), tempered glass, or other materials with sufficient strength and transparency. Operators can directly observe the working status of the internal milling mechanism 2, the grinding status of the electrode plate 55, and the chip collection status through the cover 6, and can monitor the processing process in real time without opening the cover 6.

[0060] By setting up a transparent cover 6, the processing area is enclosed and protected, while ensuring good visibility, making it easy for operators to monitor the equipment's operating status in real time, thus improving the equipment's safety, environmental friendliness, and ease of use.

[0061] See Figure 8 Based on the above embodiments, the working process of this application is as follows: S1: The loading and unloading robot places the electrode plate 55 on the flipping frame 44. The centering cylinder 51 pushes the electrode plate 55 to center it in the vertical direction. The rotating clamping arm 49 rotates and presses the electrode plate 55 under the drive of the clamping cylinder 14, fixing it on the flipping frame 44. S2: The flipping cylinder 45 drives the flipping frame 44 to flip upward to the vertical direction, the positioning plate 48 and the support beam 46 are clamped together, and the clamping cylinder rotates downward to press against the positioning plate 48, so that the flipping frame 44 is completely fixed, ensuring the stability during the grinding process. S3: The lead screw drive motor 28 drives the lead screw 54 to rotate, which drives the third slider 34 to slide from left to right along the fourth guide rail 19. The vision device 56 scans and identifies the electrode plate 55 to obtain the position and shape information of the electrode plate 55. After the scan is completed, the vision device 56 returns to the right side, and the protective cover 57 forms protection for it. S4: Based on the information obtained by the scanning component 4, the control system controls the milling mechanism 2 to mill and polish the electrode plate 55; the lifting drive motor 40 drives the crossbeam assembly 8 to rise and fall to a suitable height via the lifting belt 41 and the synchronous chain 38; the transverse drive motor 25 drives the new power head 9 to move left and right to the grinding start position via the transverse belt 24; the depth feed motor 26 drives the slide assembly 21 to drive the milling cutter assembly 22 to feed along the normal direction of the electrode plate 55 to the set grinding depth; the milling cutter 29 drive motor 27 drives the milling cutter 29 to rotate at high speed and mill the surface of the electrode plate 55 according to the preset path; during the grinding process, the chip collection belt 5 runs continuously to collect the generated waste chips and transport them to the centralized collection point; S5: After grinding is completed, clamping cylinder 14 is released, flipping cylinder 45 drives flipping frame 44 to return to the initial horizontal position, rotating clamping arm 49 opens, and loading and unloading robot unloads the ground electrode plate 55. At the same time, chip collection belt 5 continues to run until the waste chips are completely discharged.

[0062] In addition, this application also has the following beneficial effects: ① High degree of automation: Through the coordinated operation of the flipping loading and unloading mechanism 3, the scanning component 4 and the milling mechanism 2, the continuous operation of automatic loading and unloading, automatic positioning and automatic grinding of the electrode plate 55 is realized, which improves production efficiency.

[0063] ② High polishing precision: The scanning component 4 can accurately acquire the position and shape information of the electrode plate 55, and the control system optimizes the polishing path and depth parameters accordingly to ensure uniform polishing. The vision device 56 can adopt various forms such as 3D camera, laser profilometer or structured light scanner to adapt to electrode plates 55 with different materials and surface properties.

[0064] ③ Wide range of applications: This application is not only applicable to copper particle electrode 55, but also to the surface treatment of electrode 55 of various metal particles such as nickel and cobalt, and has good versatility.

[0065] ④ Safety and environmental protection: The cover 6 effectively prevents particles generated during grinding from flying everywhere, and the chip collection belt 5 collects waste chips in a timely manner, improving the working environment and ensuring operational safety.

[0066] ⑤ Compact structure: The layout of each component is reasonable, the whole machine occupies a small area, and it is convenient for workshop layout and maintenance.

[0067] ⑥ Independent operation without mutual interference: Multiple grinding machines can be arranged in parallel, and each device has an independent control system and mechanical structure. Different grinding parameters can be set according to the specifications, materials and process requirements of the board. When one device fails or is under maintenance, it will not affect the normal operation of other devices, thus improving the reliability of the entire system.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
