[0018] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0019] like Figures 1 to 21 As shown, an embodiment of the present invention provides a microprocessor device applied to the surface of a battery cell electrode, comprising: Main shaft 1 for embossing the surfaces of the positive and negative electrodes of the battery cell; Multiple support plates, the outer edges of which are formed with multiple embossed protrusions, are fitted onto the outside of the main shaft body 1. The multiple support plates include circular plates 33 and polygonal plates 34. Multiple circular pieces 33 have multiple embossed protrusions evenly distributed on their outer circular surfaces. The multiple circular pieces 33 are in close contact to form a cylindrical structure. The multiple embossed protrusions on the outer circular surfaces of the cylindrical structure are evenly distributed to form a first embossed protrusion group with a regular shape. The regular-shaped positive and negative electrode surfaces of the battery cell are embossed by rolling. Each side of a plurality of polygonal pieces 34 is provided with a different preset number of embossed protrusions. The plurality of polygonal pieces 34 are in close contact to form a prism structure. The embossed protrusions on the multiple outer surfaces of the prism structure are evenly distributed into multiple second embossed protrusion groups of special shapes. The embossing treatment of the positive and negative electrode surfaces of the special-shaped battery cell is carried out by applying vertical pressure. Two clamping parts 2 are detachably connected to both ends of the main shaft body 1, and the two clamping parts 2 are in close contact with the bearing plates on both sides respectively.

[0020] In this embodiment, a cylindrical structure is formed by the close contact of multiple circular pieces 33, and multiple embossed protrusions on the outer circular surface of the cylindrical structure are evenly distributed into a first embossed protrusion group with a regular shape, and the embossing treatment of the positive and negative electrode surfaces of the regular-shaped battery cell is carried out by rolling. Each side of a plurality of polygonal pieces 34 is provided with a different preset number of embossed protrusions. The plurality of polygonal pieces 34 are in close contact to form a prism structure. The embossed protrusions on the multiple outer surfaces of the prism structure are evenly distributed into multiple second embossed protrusion groups of special shapes. The embossing treatment of the positive and negative electrode surfaces of the special-shaped battery cell is carried out by applying vertical pressure. In practical applications, multiple circular pieces 33 are selected and assembled on the outside of the main shaft 1 according to the shape of the positive and negative electrodes of the battery cell, or multiple polygonal pieces 34 are selected and assembled on the outside of the main shaft 1, which can meet the embossing requirements of the positive and negative electrodes of different shapes of battery cells. Existing microprocessor devices can only meet the embossing requirements of the positive and negative electrode surfaces of regularly shaped battery cells; The existing microprocessor device manufacturing process is difficult and inefficient because the embossing bumps are too concentrated and can easily affect adjacent embossing bumps. The present invention divides the column structure used to support the embossed protrusions into multiple support pieces, and sets multiple embossed protrusions on the outer edge of each support piece. Each support piece is processed separately, which can reduce the impact on adjacent embossed protrusions, help reduce processing difficulty, improve processing efficiency, and reduce processing costs. It can disassemble and replace individual carrier plates. If some embossed protrusions are damaged during use, only the carrier plate with the damaged embossed protrusions needs to be replaced, without the need to scrap the whole piece, thus reducing the cost of use.

[0021] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the spindle body 1 includes: The bearing shaft 12 has multiple bearing plates fitted on its outer side; A connecting shaft 11 is integrally formed at both ends of the bearing shaft 12. The outer diameter of the connecting shaft 11 is smaller than the outer diameter of the bearing shaft 12. Two clamping pieces 2 are threadedly connected to the outer sides of the two connecting shafts 11 respectively.

[0022] In this embodiment, since the outer diameter of the connecting shaft 11 is smaller than the outer diameter of the bearing shaft 12, it is convenient to fit multiple bearing pieces on the outside of the bearing shaft 12, which helps to improve the assembly efficiency of multiple bearing pieces.

[0023] like Figure 5As shown, in an optional embodiment of the present invention, a plurality of carrier plates are provided with a through-hole 31 at their center, and the inner diameter of the through-hole 31 is adapted to the outer diameter of the carrier shaft 12.

[0024] In this embodiment, the inner diameter of the fitting hole 31 is adapted to the outer diameter of the bearing shaft 12 to ensure the fitting stability of multiple bearing pieces on the outside of the bearing shaft 12 and to ensure the accuracy of the positional distribution of multiple embossed protrusions on the multiple bearing pieces.

[0025] like Figure 2 , Figure 3 and Figure 5 As shown, in an optional embodiment of the present invention, the microprocessor device further includes: Keyway 13, the keyway 13 is formed on the outer circular surface of the bearing shaft 12, and the keyway 13 extends along the axial direction of the bearing shaft 12; Positioning key 4, the positioning key 4 is located in the keyway 13, and part of the positioning key 4 is exposed; The positioning groove 32 is disposed through multiple support plates and is connected to the fitting hole 31. The positioning groove 32 is adapted to the positioning key 4 to accommodate the exposed part of the positioning key 4.

[0026] In this embodiment, the positioning of multiple carrier plates and the carrier shaft 12 is achieved by positioning key 4, keyway 13 and positioning groove 32, which prevents multiple carrier plates from rotating outside the carrier shaft 12, ensures the angular accuracy of multiple carrier plates outside the carrier shaft 12, and ensures the accuracy of the positional distribution of multiple embossed protrusions on multiple carrier plates.

[0027] like Figure 2 and Figure 4 As shown, in an optional embodiment of the present invention, a connecting hole 21 is provided through the center of the clamping member 2, the connecting hole 21 is threadedly connected to the connecting shaft 11, and an avoidance cavity 22 is formed on the side of the clamping member 2 that abuts against the bearing plate to avoid the positioning key 4 and the end of the bearing shaft 12.

[0028] In this embodiment, the clamping member 2 and the connecting shaft 11 are detachably connected by the threaded connection of the connecting hole 21 and the connecting shaft 11; by setting the relief cavity 22, the ends of the bearing shaft 12 and the positioning key 4 are allowed to enter the relief cavity 22 to ensure that the clamping member 2 can fully contact the bearing plate, thereby ensuring the stability of the bearing plate outside the bearing shaft 12.

[0029] In an optional embodiment of the present invention, a plurality of embossed protrusions on adjacent circular pieces 33 are staggered at a predetermined angle along the circumferential direction of the circular pieces 33, wherein, , Indicates the preset angle; This indicates the angle between the distribution of adjacent embossed protrusions on the circular piece 33.

[0030] In this embodiment, by distributing multiple embossed protrusions on adjacent circular pieces 33 at a preset angle along the circumference of the circular pieces 33, different embossed protrusion distribution requirements can be met, thereby satisfying different embossing treatment requirements on the positive and negative electrode surfaces of the battery cell. Specifically, ,in, Indicates the preset angle; This indicates the included angle between adjacent embossed protrusions on the circular piece 33; When the preset angle is zero or the preset angle is equal to the angle between the preset angle and the distribution angle of adjacent embossed bumps, that is... At times, such as Figure 11 As shown in the axial view along the main shaft 1, the embossed bumps on adjacent circular pieces 33 are correspondingly distributed. After the positive and negative electrode surfaces of the battery cell are embossed, a neat matrix distribution of micro-uneven microstructures is formed on the positive and negative electrode surfaces, such as... Figure 13 As shown; When the preset angle is between zero and the angle between the distribution of adjacent embossed protrusions on each circular piece 33, that is... At times, such as Figure 12 As shown in the view along the axial direction of the main shaft 1, the embossed protrusions on adjacent circular pieces 33 are staggered in the circumferential direction of the circular pieces 33; after the positive and negative electrode surfaces of the battery cell are embossed, a staggered and uniformly distributed micro-uneven structure is formed on the positive and negative electrode surfaces of the battery cell, such as... Figure 14 As shown; In practical applications, the preset angle can be half the angle between the distribution of adjacent embossed protrusions on each circular piece 33, that is... This ensures that the embossed protrusions on one circular piece 33 correspond to the center of the space between two adjacent embossed protrusions on another circular piece 33, such as... Figure 12 As shown; Existing microprocessor devices use integral embossing. If it is necessary to process embossing with radial misalignment, the processing difficulty is greater, and it may even be impossible to process.

[0031] In an optional embodiment of the present invention, a plurality of embossed protrusions on the outer circular surface of a plurality of circular pieces 33 protrude beyond the outer circular surface of the clamping member 2 by a predetermined distance, the predetermined distance being greater than the height of the plurality of embossed protrusions.

[0032] In this embodiment, the multiple embossed protrusions on the outer circular surfaces of the multiple circular pieces 33 protrude beyond the outer circular surfaces of the clamping member 2 by a predetermined distance. This ensures the clamping contact area between the clamping member 2 and the circular pieces 33, giving the cylinder formed by the multiple circular pieces 33 a certain strength and preventing deformation of the circular pieces 33. The predetermined distance is greater than the height of the multiple embossed protrusions, ensuring that the multiple embossed protrusions fully contact the positive and negative electrode surfaces of the battery cell during embossing treatment, preventing contact between the clamping member 2 and the positive and negative electrode surfaces of the battery cell, and ensuring the embossing treatment effect. In specific applications, the predetermined distance can be 1mm.

[0033] In an optional embodiment of the present invention, each side of the plurality of polygonal pieces 34 is provided with an arrangement area of ​​different preset lengths, and a plurality of embossed protrusions are evenly distributed in the arrangement area.

[0034] In this embodiment, each side of a plurality of polygonal pieces 34 is provided with an arrangement area of ​​different preset lengths, and a plurality of embossed protrusions are evenly distributed within the arrangement area. Each polygonal piece 34 has an arrangement area of ​​different preset lengths on the same side, and the arrangement area contains a plurality of embossed protrusions evenly distributed within it. This allows the plurality of polygonal pieces 34 to be in close contact, forming a prism structure. Each side of the prism structure is formed with a second group of embossed protrusions evenly distributed in a special shape. The special shape of the second group of embossed protrusions matches the shape of the positive and negative electrodes of the battery cell, thereby achieving a vertical... The embossing process is applied to the surfaces of the positive and negative electrodes of the specially shaped battery cells using a pressure method. Each side of the prism structure is formed with a group of second embossed protrusions evenly distributed in a specially shaped manner, which can meet the embossing requirements of the positive and negative electrodes of different shaped battery cells. The preset length is determined according to the shape of the positive and negative electrodes of the specially shaped battery cells; that is, the surfaces of the specially shaped battery cells after embossing have a uniformly distributed micro-convex and concave structure. The length of each column of the uniformly distributed micro-convex and concave structure is the preset length of the arrangement area on the edge of the same position of each polygonal piece 34, such as... Figure 21 The diagram shows the state of the positive and negative electrode surfaces of the battery cell after embossing, where the length L is the length of each column of the uniformly distributed micro-uneven structure.

[0035] In an optional embodiment of the present invention, the plurality of embossed protrusions are dot-shaped protrusions 51, spaced-apart line-shaped protrusions 52, or blade-shaped protrusions 53.

[0036] In this embodiment, the multiple embossing protrusions are any one of dot-shaped protrusions 51, spaced line-shaped protrusions 52, or blade-shaped protrusions 53, which can meet the embossing treatment requirements of different positive and negative electrode surfaces of the battery cell. In practical applications, by adjusting the preparation method, it is possible to process dot-shaped protrusions 51, spaced linear protrusions 52, or cutting edge protrusions 53; Specifically: when the supporting sheet is a circular sheet 33, a sheet-shaped substrate is obtained; the sheet-shaped substrate is stamped to obtain a first initial sheet with a fitting hole 31. The first initial sheet has a circular structure, wherein a positioning groove 32 is formed on the first initial sheet, and the positioning groove 32 is connected to the fitting hole 31; the first initial sheet is positioned by the positioning groove 32, and the outer circular surface of the first initial sheet is ground at a preset inclination angle to form an initial cutting edge structure on the outer circular surface of the first initial sheet. The edges of the initial cutting edge structure are laser-trimmed to obtain a circular sheet 33 with embossed protrusions 53 in the shape of cutting edge protrusions; wherein the preset inclination angle is the inclination angle of the side of the cutting edge protrusion 53; The outer surface of the first grinding wheel is used to grind the outer edge of the initial cutting edge structure. Simultaneously, the first initial sheet is rotated intermittently at a first preset rotation angle. Multiple evenly distributed groove structures are sequentially machined on the outer edge of the initial cutting edge structure, forming initial spaced linear protrusions 52 on the outer surface of the first initial sheet. The edges of the initial spaced linear protrusions 52 are then laser-trimmed to obtain a circular sheet 33 with embossed protrusions in the shape of spaced linear protrusions 52. The first grinding wheel is a disc-shaped grinding wheel with a planar cross-section on its outer surface. The width of the first grinding wheel is equal to the width of the groove structure. The first preset rotation angle is the included angle between adjacent embossed protrusions in the shape of spaced linear protrusions 52 on the circular sheet 33. ; ;in, Indicates the first preset rotation angle; This refers to the included angle between adjacent embossed protrusions 52 on the circular piece 33, which are spaced-apart linear protrusions, such as... Figure 7 As shown; This indicates the number of embossed protrusions 52 spaced out on the circular piece 33; The outer surface of the second grinding wheel is used to grind the outer edge of the initial cutting edge structure. Simultaneously, the first initial sheet is rotated intermittently at a second preset rotation angle. Multiple evenly distributed notch structures are sequentially machined on the outer edge of the initial cutting edge structure, forming initial dot-shaped protrusions 51 on the outer surface of the first initial sheet. The edges of the initial dot-shaped protrusions 51 are then laser-trimmed to obtain a circular sheet 33 with embossed protrusions in the shape of dot-shaped protrusions 51. The dot-shaped protrusions 51 are pyramidal in shape, and the cross-section of the outer surface of the second grinding wheel is triangular, with the triangular structure having the same shape as the notch structure, further reducing processing difficulty and improving processing efficiency. The second preset rotation angle is the included angle between adjacent embossed protrusions in the shape of dot-shaped protrusions 51 on the circular sheet 33. ; ;in, Indicates the second preset rotation angle; This refers to the included angle between adjacent embossed protrusions 51 on the circular piece 33, such as... Figure 6 As shown; This indicates the number of embossed protrusions 51 on the circular piece 33; the above example uses a pyramid shape for the protrusions 51, but in specific applications, the cross-section of the protrusions 51 can also be circular or polygonal, which can be obtained through laser trimming. When the supporting sheet is a polygonal sheet 34, a sheet-like substrate is obtained; the sheet-like substrate is stamped to obtain a second initial sheet with a fitting hole 31. The second initial sheet has a polygonal structure, wherein a positioning groove 32 is formed on the second initial sheet, and the positioning groove 32 is connected to the fitting hole 31; the second initial sheet is positioned by the positioning groove 32, and multiple edges of the second initial sheet are ground to form an arrangement area with a preset length. The two sides of each arrangement area are ground at a preset tilt angle to form an initial cutting edge structure in the arrangement area of ​​multiple edges of the second initial sheet. The edges of the multiple initial cutting edge structures are laser-trimmed to obtain a polygonal sheet 34 with embossed protrusions 53 in the shape of cutting edge protrusions; wherein the preset tilt angle is the tilt angle of the side of the cutting edge protrusion 53. The outer circumference of the third grinding wheel is used to grind the outer edge of the initial cutting edge structure. Simultaneously, the second initial sheet is moved intermittently at a first preset distance, sequentially machining multiple evenly distributed groove structures on the outer edge of the initial cutting edge structure. This forms initial spaced linear protrusions 52 on the arrangement areas of multiple edges of the second initial sheet. The edges of the initial spaced linear protrusions 52 are then laser-trimmed to obtain a polygonal sheet 34 with embossed protrusions in the shape of spaced linear protrusions 52. The third grinding wheel is a disc-shaped grinding wheel, the outer circumference of the first grinding wheel has a planar cross-section, and the width of the third grinding wheel is equal to the width of the groove structure. The first preset distance is the distance between two adjacent groove structures on the polygonal sheet 34. Figure 18 As shown, distance L1 is the distance between two adjacent slot structures on polygonal piece 34; The outer circumference of the second grinding wheel is used to grind the outer edge of the initial cutting edge structure. Simultaneously, the second initial sheet is moved intermittently at a second preset distance, sequentially machining multiple evenly distributed notch structures on the outer edge of the initial cutting edge structure. This forms initial dot-shaped protrusions 51 on the arrangement areas of multiple edges of the second initial sheet. The edges of the initial dot-shaped protrusions 51 are then laser-trimmed to obtain a polygonal sheet 34 with embossed protrusions in the shape of dot-shaped protrusions 51. The dot-shaped protrusions 51 are pyramidal in shape, and the cross-section of the outer circumference of the second grinding wheel is a triangular structure, with the triangular structure having the same shape as the notch structure, to further reduce processing difficulty and improve processing efficiency. The second preset distance is the distance between two adjacent notch structures on the polygonal sheet 34. Figure 19 As shown, distance L2 is the distance between two adjacent notch structures on polygonal piece 34; the above example uses the pyramid shape of dotted protrusion 51. In specific applications, the cross-section of dotted protrusion 51 can also be circular or polygonal, which can be obtained through laser trimming. In this embodiment, the multiple embossed bumps are any one of dot-shaped bumps 51, spaced-line bumps 52, and cutting edge bumps 53. The preparation methods of embossed bumps of different shapes are related, that is, the processing of spaced-line bumps 52 or dot-shaped bumps 51 can be completed by making simple adjustments based on the preparation method of cutting edge bumps 53, which further reduces the processing difficulty and improves the processing efficiency.

During use, if some embossing protrusions are damaged, only the support piece with the damaged embossing protrusions needs to be replaced, without scrapping the whole piece, thus reducing the cost of use; through positioning key 4 and keyway 13 The positioning groove 32 positions multiple carrier plates relative to the carrier shaft 12, preventing the carrier plates from rotating outside the carrier shaft 12 and ensuring the angular accuracy of the carrier plates outside the carrier shaft 12, thus ensuring the accurate positional distribution of the multiple embossed protrusions on the carrier plates. By distributing the multiple embossed protrusions on adjacent circular plates 33 at a preset angle along the circumference of the circular plates 33, different embossed protrusion distribution requirements can be met, thereby satisfying different embossing treatment requirements for the positive and negative electrode surfaces of regularly shaped battery cells. The clamping member 2 and the connecting shaft 11 are detachably connected via a threaded connection through the connecting hole 21. The clearance cavity 22 allows the ends of the carrier shaft 12 and the positioning key 4 to be positioned... The clamping member 2 enters the clearance cavity 22 to ensure that it can fully contact the bearing plate, thus ensuring the stability of the bearing plate on the outside of the bearing shaft 12. The multiple embossed protrusions on the outer circular surface of the multiple circular pieces 33 protrude from the outer circular surface of the clamping member 2 by a predetermined distance, which can ensure the clamping contact area between the clamping member 2 and the circular pieces 33, so that the cylindrical structure formed by the multiple circular pieces 33 has a certain strength and avoids deformation of the circular pieces 33. The predetermined distance is greater than the height of the multiple embossed protrusions. When performing embossing treatment on the surface of the regular-shaped positive and negative electrodes of the battery cell, the multiple embossed protrusions can fully contact the surface of the regular-shaped positive and negative electrodes of the battery cell, avoiding contact between the clamping member 2 and the surface of the positive and negative electrodes of the battery cell, thus ensuring the embossing treatment effect.Each side of a plurality of polygonal pieces 34 is provided with an arrangement area of ​​different preset lengths. Multiple embossed protrusions are evenly distributed within the arrangement area. Each polygonal piece 34 has an arrangement area of ​​different preset lengths on the same side, and multiple embossed protrusions are evenly distributed within the arrangement area. This allows the polygonal pieces 34 to contact each other closely, forming a prism structure. Each side of the prism structure is formed with a group of second embossed protrusions evenly distributed in a special shape. The special shape of the second embossed protrusion group matches the shape of the positive and negative electrodes of the special-shaped battery cell, thus performing embossing treatment on the surface of the special-shaped battery cell positive and negative electrodes by applying vertical pressure. The presence of a group of second embossed protrusions evenly distributed in a special shape on each side of the prism structure can meet the embossing treatment requirements for the surfaces of special-shaped battery cell positive and negative electrodes. The multiple embossed protrusions can be any of the following types: dot-shaped protrusions 51, spaced-apart line-shaped protrusions 52, and blade-shaped protrusions 53, which can meet the embossing treatment requirements for the surfaces of different battery cell positive and negative electrodes.

That is, the support sheet and its multiple embossed protrusions on the outer edge are processed separately, which greatly reduces the processing difficulty, improves the processing efficiency, and reduces the processing cost. The combination of grinding and laser finishing enables the formation of multiple embossed protrusions on the outer edge of the support sheet. Compared with existing laser ablation or mechanical engraving, this reduces the cost of processing equipment.

Figure 6 As shown; This indicates the number of embossed protrusions 51 on the circular piece 33; the above example uses a pyramid shape for the protrusions 51, but in specific applications, the cross-section of the protrusions 51 can also be circular or polygonal, which can be obtained through laser trimming.

The third grinding wheel is a disc-shaped grinding wheel, the outer circumference of the first grinding wheel has a planar cross-section, and the width of the third grinding wheel is equal to the width of the groove structure.
