[0002] In the production process of storage batteries, after the electrode group and the battery shell are assembled, the battery needs to be filled with a sufficient amount of sulfuric acid electrolyte and then energized to convert the green plates into positive and negative plates with electrochemical activity.

[0003] During the acid filling process, the impact force generated by the sulfuric acid electrolyte entering the battery casing will damage the plates and cause the lead powder on the plates to fall off. In practice, it is found that placing a protective plate above the plates can act as a buffer during the acid filling process and avoid damage to the plates.

[0004] The protective plate is a paper or plastic strip with porous surface. When in use, multiple strips of protective plates need to be cut into blocks of equal size.

The second cylinder 41 is arranged on the storage platform 13, and the telescopic end of the second cylinder 41 is connected to the top of the cutter 42. The bottom of the cutter 42 is triangular, and the cutter 42 is used to cut the protective plate. The cutting platform 44 is plate-shaped, and a plurality of grooves are arranged on the cutting platform 44. The number of the grooves is consistent with the number of strips of the protective plate, and the width of the groove is not less than the width of the protective plate; along the moving direction of the protective plate, the cutting platform 44 is provided with a knife groove near the cutter 42, and the width of the knife groove is not less than the width of the cutter 42. The conveying roller 22 delivers the protective plate into the groove, and the cutter 42 cuts from above the knife groove.

[0031] In order to avoid deviation of the two sides of the cutter 42, a slide rail 43 is provided on the side of the vertical plate 12 close to the cutting unit, and the slide rail 43 matches the cutter 42. Specifically, a slide rail 43 is provided on each side of the second cylinder 41, and the direction of the slide rail 43 is the same as the moving direction of the telescopic end of the second cylinder 41. The slide rail 43 is fixedly connected to the vertical plate 12, and a slider matching the slide rail 43 is fixedly connected to the side of the cutter 42. When the second cylinder 41 is started, the cutter 42 is driven to move up and down along the slide rail 43.

[0032] like Figure 4 As shown, the positioning unit is arranged outside the cutting unit, and the positioning unit includes a first cylinder 31, a positioning plate 32 and a positioning column 33. The first cylinder 31 is fixed to the bottom of the storage platform 13, and the telescopic end of the first cylinder 31 is connected to the positioning plate 32. A plurality of positioning columns 33 are evenly spaced on the other side of the positioning plate 32 away from the first cylinder 31. The first cylinder 31 drives the positioning columns 33 to press down through the positioning plate 32, and press against the surface of the protective plate to limit the displacement of the protective plate. As an implementable embodiment, the positioning plate 32 is in a "convex" shape, and the retracted part of the positioning plate 32 is connected to the telescopic end of the first cylinder 31. A plurality of threaded holes are evenly spaced on the expanded part of the positioning plate 32, and the positioning column 33 is threadedly connected in the threaded hole. Specifically, the positioning column 33 can be a bolt.

[0033] When in use, the conveying roller 22 delivers the protective plate to the groove of the cutting platform 44, the first cylinder 31 above the cutting platform 44 is started first, the positioning column 33 pops out and reaches the surface of the protective plate, and then the second cylinder 41 is started, driving the cutter 42 to press down and cut the protective plate into two sections.

[0034] The cutting platform 44 is movably connected to the shell, and sliding guide rails 45 are provided on both sides of the shell. The cutting platform 44 matches the sliding guide rails 45. The cutting platform 44 is driven by a power mechanism, which can be a cylinder or a motor. The power mechanism drives the cutting platform 44 to move back and forth along the sliding guide rails 45.

[0035] As an implementation method, Figure 5 As shown, the cutting platform 44 has two parts, including a first cutting platform 441 and a second cutting platform 442. The two cutting platforms are arranged in parallel. The first cutting platform 441 is located on the inner side, close to the conveying unit, and the second cutting platform 442 is located on the outer side, away from the conveying unit. A telescopic mechanism is arranged under the first cutting platform 441. The telescopic mechanism controls the up and down movement of the cutting platform 44. The paper cutting device first cuts on the second cutting platform 442. After cutting, the power mechanism drives the two cutting platforms 44 to move outward. When the first cutting platform 441 moves to the bottom of the cutter 42, the telescopic mechanism is started to drive the first cutting platform 441 to move upward, and the paper cutting device cuts on the first cutting platform 441.

[0036] Specifically, the first cutting platform 441 and the second cutting platform 442 are arranged on a base 451, the base 451 is slidably connected to the sliding guide rail 45, the base 451 is fixedly connected to the second cutting platform 442 and movably connected to the first cutting platform 441, a sliding rod passing through the base 451 is arranged below the first cutting platform 441, and the sliding rod is connected to a telescopic cylinder below the base 451.

[0039] When in use, the protective plate passes through the guide shaft 21 and enters between the two conveying rollers 22. The conveying roller 22 sends the protective plate into the groove in the cutting platform 44. The first cylinder 31 is started to drive the positioning plate 32 to drive the positioning column 33 to press down to the surface of the protective plate to position the protective plate and prevent the protective plate from displacement. The second cylinder 41 is started to drive the cutter 42 to press down. The tip of the cutter 42 resists the surface of the protective plate to cut off the protective plate.
