[0002] Lithium battery electrode sheets are composed of positive and negative electrodes. The positive electrode sheets are usually composed of active materials, conductive agents, and binders. Active materials are the main components of positive electrodes. Negative electrodes are also composed of active materials, conductive agents, and binders. Graphite is usually used as the negative electrode active material because it has high electrochemical stability and good ion conductivity. When processing lithium battery electrode sheets, a fixed structure is needed to fix them so that the electrode sheets can be stored. The number of partitions in the existing lithium battery electrode sheet fixing structure is fixed. Although the staff can adjust the position of the partition to clamp and fix the electrode sheet, the number of partitions cannot be adjusted according to the thickness of the electrode sheet.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 6 As shown, a lithium battery electrode sheet separator fixing structure comprises a storage box 1, both sides of the inner wall of the storage box 1 are provided with positioning grooves 2, and fixing plates 3 are slidably arranged in the two positioning grooves 2, and each fixing plate 3 is provided with a mounting groove 4 on a side surface away from each other, and each mounting groove 4 is provided with a sliding groove 5 on the bottom surface, and each sliding groove 5 is slidably arranged with a slider 6, and each slider 6 is fixedly installed with a trapezoidal block 7 on the upper surface;

[0025] A threaded hole 8 is formed through the top surface of each mounting groove 4 , a threaded rod 9 is threadedly disposed in each threaded hole 8 , and a rotating plate 10 is fixedly mounted on the upper end of each threaded rod 9 .

[0026] When in use, the staff rotates the threaded rod 9 so that one side of the trapezoidal block 7 is out of contact with the inner wall of the mounting groove 4, and then the staff places the electrode sheet between the two fixing plates 3. Then the staff moves the fixing plates 3 so that the two adjacent fixing plates 3 clamp the electrode sheet. Then the staff rotates the threaded rod 9 in the opposite direction so that the trapezoidal block 7 moves along the mounting groove 4, so that one side of it fits with the inner wall surface of the positioning groove 2, so that the fixing plate 3 is fixed in position and clamps the electrode sheet. When the staff rotates the threaded rod 9 so that one side of the trapezoidal block 7 is out of contact with the inner wall of the mounting groove 4, the staff can pull the fixing plate 3 to separate it from the storage box 1. After placing the new fixing plate 3 inside the storage box 1, the staff can rotate the threaded rod 9 in the opposite direction so that one side of the trapezoidal block 7 fits with the inner wall of the mounting groove 4, so that the new fixing plate 3 is fixed in position, so that it plays a role of clamping and fixing. When processing electrode sheets of different thicknesses, the staff does not need to replace the entire fixing structure or make complicated adjustments, which greatly reduces production time and cost and improves production efficiency.

[0027] In another embodiment of the utility model, a round block 11 is fixedly mounted on the lower end of each threaded rod 9, a rotating rod 12 is rotatably mounted on the lower surface of each round block 11, and a rotating ball 13 is fixedly mounted on the lower end of each rotating rod 12.

[0028] By setting the rotating ball 13, when the threaded rod 9 rotates, the rotating ball 13 can push the trapezoidal block 7, so that the lower end of the threaded rod 9 does not need to contact the trapezoidal block 7, which greatly reduces the wear on the surface of the threaded rod 9 and extends the service life of the threaded rod 9.

[0029] In another embodiment of the utility model, a slide bar 14 is fixedly installed between the two sides of the inner wall of each slide groove 5, and each slider 6 is slidably arranged on one side of the corresponding slide bar 14;

[0030] The other side of the shaft of each slide rod 14 is sleeved with an elastic member 15 capable of compression and reset.

[0031] The elastic member 15 is a spring.

[0032] By setting the spring, when the staff rotates the threaded rod 9 in the reverse direction and the rotating ball 13 no longer pushes the trapezoidal block 7, the trapezoidal block 7 can be automatically reset under the action of the elastic force generated when the spring is reset, and the staff does not need to reset it manually, thereby reducing the staff's workload.

[0033] In another embodiment of the utility model, a connecting groove 16 is formed on the bottom surface of each positioning groove 2, and a plurality of rotating shafts 17 are rotatably mounted on both sides of the inner wall of each connecting groove 16, and a rotating roller 18 is sleeved on the shaft body of each rotating shaft 17.

[0034] By providing the roller 18 , when the fixing plate 3 moves along the positioning groove 2 , the sliding friction between the fixing plate 3 and the positioning groove 2 is converted into rolling friction, which greatly reduces the wear of the fixing plate 3 and prolongs the service life of the fixing plate 3 .

[0035] In another embodiment of the utility model, a positioning frame 19 is fixedly mounted on the upper surface of each storage box 1;

[0036] A protective cover 20 is disposed on the upper surface of the storage box 1 , and a limiting groove 21 is provided on the lower surface of the protective cover 20 . The limiting groove 21 is engaged with the positioning frame 19 .

[0037] After the positioning frame 19 is engaged with the limiting groove 21 , the protective cover 20 can cover the opening of the storage box 1 , thereby protecting the electrode sheet inside the storage box 1 .

[0038] The working principle of this lithium battery electrode sheet separator fixing structure:

[0039] When in use, the staff rotates the threaded rod 9 so that one side of the trapezoidal block 7 is out of contact with the inner wall of the mounting groove 4, and then the staff places the electrode sheet between the two fixing plates 3. Then the staff moves the fixing plates 3 so that the two adjacent fixing plates 3 clamp the electrode sheet. Then the staff rotates the threaded rod 9 in the opposite direction so that the trapezoidal block 7 moves along the mounting groove 4, so that one side of it fits with the inner wall surface of the positioning groove 2, so that the fixing plate 3 is fixed in position and clamps the electrode sheet. When the staff rotates the threaded rod 9 so that one side of the trapezoidal block 7 is out of contact with the inner wall of the mounting groove 4, the staff can pull the fixing plate 3 to separate it from the storage box 1. After placing the new fixing plate 3 inside the storage box 1, the staff can rotate the threaded rod 9 in the opposite direction so that one side of the trapezoidal block 7 fits with the inner wall of the mounting groove 4, so that the new fixing plate 3 is fixed in position, so that it plays a role of clamping and fixing. When processing electrode sheets of different thicknesses, the staff does not need to replace the entire fixing structure or make complicated adjustments, which greatly reduces production time and cost and improves production efficiency.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
