DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] See also Figure 1-4 The utility model provides a sodium ion battery pole piece pressing and slicing device, comprising a base frame 1 in an inverted concave structure, a slicing table 2 is fixedly connected to the top of the base frame 1, a row of communicating circular holes 3 are provided on the top of the base frame 1 and the slicing table 2, a lifting mounting plate 4 is arranged above the base frame 1, a plurality of cylindrical cutters 5 for slicing the pole piece are fixedly connected to the bottom of the mounting plate 4, and a lower pressing block 6 is provided in the cylindrical cutter 5, which can move downward after the cylindrical cutter 5 slices the pole piece, so that The design can place the electrode on the top of the slicing table 2. When the position of the mounting plate 4 is lowered, multiple cylindrical cutters 5 can be pressed down and extended into the corresponding circular holes 3, so that the electrode can be pressed and sliced. The cut-out molded electrode part will fall downward from the circular hole 3, and the other part will remain in the cylindrical cutter 5 and be squeezed out of the cylindrical cutter 5 by the descending pressing block 6. The staff can place a collection box at the bottom of the base frame 1 to receive the fallen molded electrode, thereby realizing the rapid collection of the sliced ​​electrode.

[0022] Specifically, in order to enable the lower pressing block 6 to move downward in the cylindrical cutter 5 and squeeze the pole piece out of the cylindrical cutter 5 after the cylindrical cutter 5 slices the pole piece, it is proposed to provide an adjusting plate 7 above the mounting plate 4 which can be synchronously lowered after the cylindrical cutter 5 is inserted into the circular hole 3, and a plurality of connecting rods 8 that penetrate the mounting plate 4 and extend to the corresponding cylindrical cutter 5 are fixedly connected to the bottom of the adjusting plate 7, and each lower pressing block 6 is respectively fixedly connected to the bottom of the corresponding connecting rod 8, so that the adjusting plate 7 can drive the plurality of connecting rods 8 to descend synchronously with the lower pressing block 6 when descending, so that the lower pressing block 6 can push the pole piece retained in the cylindrical cutter 5 downward and drop it from the circular hole 3 for easy collection.

[0023] Furthermore, longitudinal movable rods 9 are inserted and connected on both sides of the mounting plate 4, and the top sides of the two movable rods 9 facing each other are fixedly connected with racks 11 that abut against the top surface of the mounting plate 4. The movable rods 9 have springs 10 for pushing them downward, and both sides of the adjustment plate 7 are rotatably connected with gears 12 that mesh with the corresponding racks 11, so that when the mounting plate 4 drives the cylindrical cutter 5 to descend, the movable rods 9 can also follow and descend synchronously. After the cylindrical cutter 5 is inserted into the circular hole 3, the movable rods 9 will rise on the mounting plate 4 due to the contact between the bottom and the surface of the slicing table 2, so that the racks 11 will drive the adjustment plate 7 to move downward through the cooperation of the gears 12, so that the lower pressure block 6 will move downward synchronously in the cylindrical cutter 5.

[0024] It should be noted that the bottom surface of the limit block 13 and the bottom surface of the cylindrical cutter 5 are located on the same horizontal plane, so that when the mounting plate 4 descends, the limit block 13 can contact the top surface of the slicing table 2 together with the cylindrical cutter 5 at the same time, and the pressing block 6 will only descend after the cylindrical cutter 5 extends into the circular hole 3 and slices the electrode. Such a design will be more reasonable.

[0025] The specific way in which the spring 10 can push the movable rod 9 to move downward is as follows: a limit block 13 is fixedly connected to the bottom of the two movable rods 9, and the spring 10 is sleeved on the movable rod 9 and is located between the limit block 13 and the mounting plate 4, so that the spring 10 can always push the limit block 13 and the movable rod 9 to move downward through the action of its own elasticity.

[0026] In order to enable the mounting plate 4 to be raised and lowered, an inverted concave-shaped mounting frame 14 is fixedly connected to the top of the base frame 1, and a servo electric cylinder 15 with a piston rod facing downward is fixedly inserted on the mounting frame 14. The end of the piston rod of the servo electric cylinder 15 is fixedly connected to the mounting plate 4 through a bracket. When the piston rod of the servo electric cylinder 15 is extended or retracted, the mounting plate 4 can be driven to be raised and lowered, so that the cylindrical cutter 5 at the bottom can press and slice the pole piece on the slicing table 2.

[0027] See also Figure 3 Two front-to-back symmetrical guide rods are fixedly connected to the top of the cylindrical cutter 5, and the front and back sides of the adjustment plate 7 are respectively sleeved on the two guide rods, so that the adjustment plate 7 can form an upper and lower snap-fit ​​sliding connection above the mounting plate 4, thereby ensuring that the gear 12 is always meshed with the rack 11 without any front-to-back deviation or separation.

[0028] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0029] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0030] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
