[0008] As a further solution of the present invention: the bottom of the two spur racks are fixedly connected to a limit block, the top of the support base is provided with a limit slot matching the limit block, and the spur racks are slidably connected to the support base through the limit block fixedly connected to the bottom.

[0009] As a further solution of the present invention: the warping and pressing assembly includes connecting rods respectively fixedly connected to the top of one of the straight racks, and a first pressure roller is provided at the bottom of each of the two connecting rods.

[0031] See also Figures 1 to 12The present embodiment provides a sodium ion battery electrode cutting and grinding machine, comprising: a sawing machine 1, a sliding seat 7 is slidably connected to the top of the sawing machine 1, and a saw blade 4 is installed on the inner side of the sliding seat 7; a pole piece workpiece 5, the pole piece workpiece 5 is placed on the top of the sawing machine 1; a fixed seat 8, the fixed seat 8 is fixedly connected to the top of the sawing machine 1, a hydraulic cylinder 9 is installed on one side of the fixed seat 8, and the output end of the hydraulic cylinder 9 passes through the outside of the fixed seat 8 and is fixedly connected to the sliding seat 7; an auxiliary grinding mechanism, located on the back of the saw blade 4, for grinding the end of the cut pole piece workpiece 5, the auxiliary grinding mechanism includes a first grinding belt 12 and a second grinding belt 13 arranged on the back of the saw blade 4, the auxiliary grinding mechanism also includes a hanging rod 6 fixedly connected to the inner side of the sliding seat 7, the bottom of the hanging rod 6 and the inner side of the sliding seat 7 are fixedly connected to a fixed frame 10, the inner side of the fixed frame 10 is rotatably connected to a rotating shaft 11, and the outer walls of the rotating shaft 11 are respectively wound with the first grinding belt 12 and the second grinding belt 13, the fixed frame 1 A second driving motor 23 is installed on one side of 0, and the output end of the second driving motor 23 is fixedly connected to the rotating shaft 11, the auxiliary laminator includes a supporting base 14 fixedly connected to the ends of the two fixed frames 10, a first driving motor 15 is installed on one side of the supporting base 14, the output end of the first driving motor 15 passes through the other side of the supporting base 14 and is fixedly connected to a spur gear 16, a spur rack 17 is meshed with both sides of the spur gear 16, one end of the two spur racks 17 is fixedly connected to a connecting plate 21, the bottom of the connecting plate 21 is rotatably connected to a second pressing roller 22, a second pressing roller 22 is affixed to one side of the second grinding belt 13, and the other second pressing roller 22 is affixed to the other side of the first grinding belt 12, and the two second pressing rollers 22 are staggered, and the bottoms of the two spur racks 17 are fixedly connected to a limit block, and a limit slide groove matching the limit block is provided on the top of the supporting base 14, and the spur rack 17 is slidably connected to the supporting base 14 through the limit block fixedly connected to the bottom;

[0032] First, a clamping device for fixing the pole piece workpiece 5 is fixedly installed on the top of the sawing machine 1. Since how to fix the pole piece workpiece 5 is a prior art, this solution does not elaborate on it in detail.

[0033] The interior of the sliding seat 7 is provided with a power component for driving the saw blade 4 to perform a cutting operation. The power component can be composed of a servo motor or the like for driving the saw blade 4 to perform a cutting operation. Since it is a prior art, this solution does not elaborate on it in detail.

[0034] When the pole piece workpiece 5 is fixed on the top of the sawing machine 1 and needs to be cut, and the saw blade 4 cuts the pole piece workpiece 5, at the same time, the output end of the hydraulic cylinder 9 drives the sliding seat 7 to drive the saw blade 4 to move horizontally, thereby performing a cutting operation on the pole piece workpiece 5;

[0035] The diameters of the first grinding belt 12 and the second grinding belt 13 are smaller than the thickness of the saw blade 4. When the sliding seat 7 drives the saw blade 4 to move laterally, it drives the first grinding belt 12 and the second grinding belt 13 to move synchronously, so that the first grinding belt 12 and the second grinding belt 13 can move along the cutting path of the saw blade 4. When a part of the second grinding belt 13 enters the cutting part, the first drive motor 15 is started and the two second drive motors 23 are started. One second drive motor 23 drives a rotating shaft 11 to rewind, and the other second drive motor 23 drives a rotating shaft 11 to release (when one rotating shaft 11 completes the rewinding of the second grinding belt 13 and the first grinding belt 12, the two The output end of the second drive motor 23 runs in reverse to realize the grinding operation again), so that the second grinding belt 13 and the first grinding belt 12 move to grind the pole piece workpiece 5 at the cutting part, and the output end of the first drive motor 15 drives the spur gear 16 to rotate, thereby driving the two spur racks 17 to drive a second pressure roller 22 to move toward the second grinding belt 13 and the first grinding belt 12, so that the second grinding belt 13 entering the cutting part of the pole piece workpiece 5 can be fitted to the cutting part of the pole piece workpiece 5 for moving grinding, and the fitting grinding operation is realized while the pole piece workpiece 5 is being cut, thereby reducing the subsequent processing steps, thereby improving the overall processing efficiency of the pole piece workpiece 5;

[0036] When the second grinding belt 13 has completely entered the cutting part of the pole piece workpiece 5, and the first grinding belt 12 has not yet entered the cutting part of the pole piece workpiece 5, the output end of the first drive motor 15 drives the spur gear 16 to reset, so that the two second pressure rollers 22 no longer squeeze the second grinding belt 13 and the first grinding belt 12. Since the first grinding belt 12 and the second grinding belt 13 themselves have a certain elasticity, the first grinding belt 12 and the second grinding belt 13 can be reset under the action of their own elasticity after being not squeezed. When the second grinding belt 13 has completely entered the cutting part, the first grinding belt 12 is reset to its initial state and enters the cutting part. When most of the first grinding belt 12 has entered the cutting part of the pole piece workpiece 5, the first drive motor 15 is activated again, so that the first grinding belt 12 and the second grinding belt 13 can be squeezed again so that they fit respectively on the left and right sides of the cutting part, thereby performing synchronous grinding operations on both sides of the cutting part.

[0037] See also Figures 4 to 12, both sides of the first grinding belt 12 and the second grinding belt 13 are provided with auxiliary laminators and warping and pressing assemblies, the warping and pressing assemblies include connecting rods 18 fixedly connected to the top of a straight rack 17, and a first pressure roller 19 is provided at the bottom of the two connecting rods 18. The bottom of the first pressure roller 19 is embedded with a ball 20, and the ball 20 is against the top of the pole piece workpiece 5. The two first pressure rollers 19 are staggered and respectively adhere to the outer walls of the second grinding belt 13 and the first grinding belt 12. The warping and pressing assembly also includes a moving block 2 slidably connected to the bottom of the connecting rod 18, and the first pressure roller 19 is rotatably connected to the moving block 2. A connecting spring 3 is installed between the moving block 2 and the connecting rod 18. A rectangular block is fixedly connected to each side of the moving block 2, and a rectangular groove matching the two rectangular blocks is opened on the inner side of the connecting rod 18. The moving block 2 is slidably connected to the connecting rod 18 through the rectangular blocks fixedly connected on both sides;

[0038] The lengths of the two second pressing rollers 22 are both smaller than the lengths of the second grinding belt 13 and the first grinding belt 12, and the two first pressing rollers 19 are respectively arranged at the edges of the first grinding belt 12 and the second grinding belt 13. When a straight rack 17 drives a second pressing roller 22 to move toward the second grinding belt 13, the other straight rack 17 drives the other first pressing roller 19 to move synchronously toward the second grinding belt 13 through another connecting rod 18, so that the second pressing roller 22 presses the second grinding belt 13 while the first pressing roller 19 can push the second grinding belt 13 to move toward the cutting part of the pole piece workpiece 5 to warp outward, thereby avoiding the second grinding belt 13 or the first grinding belt 12 from being obstructed by the cutting edge in the process of moving toward the cutting part of the pole piece workpiece 5, and avoiding the edge part from being stuck by the cutting surface, so that the grinding can be carried out continuously to avoid jamming, thereby improving the overall practicality of the device;

[0039] For example, there may be tiny protrusions or burrs on the edge of the electrode workpiece 5 after cutting. The first pressing roller 19 guides the edge of the grinding belt around the protrusion by the edge warping action, ensuring that the burrs in the edge area are completely polished.

[0040] When the ball 20 at the bottom of the first pressure roller 19 is obstructed by the protrusion during movement, it can squeeze the connecting spring 3 along the edge of the protrusion and move upward to avoid the obstruction, so that the first pressure roller 19 can adaptively press the edges of the first grinding belt 12 and the second grinding belt 13, so that the device can adapt to different working conditions, thereby improving the overall practicality of the device.

[0041] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
