Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a laminate cutting device with a protective structure. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloys as the positive and negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use place high demands on the environment. With the advancement of science and technology, lithium batteries have become mainstream.

[0003] According to a disclosed method for cutting lithium battery pole pieces (publication number: CN220407256U), in the above application, a gear drives a rack to move left and right on a connecting frame, and connects a slider, a connecting block and a rack together. Driven by the rack, the slider can drive the limit assembly to move, so that the clamped lithium battery pole piece can also move.

[0004] In the above, only the pole piece is limited to prevent deviation during cutting, which may cause certain damage to the pole piece. However, during cutting, the cutter is always exposed to the outside. If an object accidentally hits the cutter, it may cause damage to the cutter, resulting in uneven cutting or unbroken cutting, which may cause certain damage to the pole piece in the stack.

The bottom of the extension rod 61 is fixedly installed with a fixed shielding plate 62, which is convenient for installing the rotating shielding plate 63. The left side of the fixed shielding plate 62 is hinged with a rotating shielding plate 63, which can block the cutter 5 and play a protective role. A cross slot 64 is provided on the front of the fixed shielding plate 62, which is convenient for installing the return spring 65 and can provide a guide for the push rod 66. The bottom of the cross slot 64 is fixedly installed with a return spring 65, which can make the push rod 66 reset after being stretched. The push rod 66, the bottom of the push rod 66 is fixedly installed on the top of the return spring 65, can be cut by the cutter The outer wall of the push rod 66 is slidably mounted on the inside of the cross slot 64. The top of the push rod 66 is fixedly mounted with an extrusion rod 67, which can squeeze the inclined rod 68 and move it to the left and right sides of the cross slot 64. The left side of the cross slot 64 is slidably mounted with an inclined rod 68, which is convenient for driving the connecting rod 610 to push and move the spring 69. The right side of the moving spring 69 is fixedly mounted on the left side of the inclined rod 68 and can be reset when not squeezed by the extrusion rod 67. The end of the moving spring 69 away from the inclined rod 68 is fixedly mounted on the left side of the cross slot 64 for fixing. The front side of the inclined rod 68 is hinged with a connecting rod 610, which can make the inclined rod 68 drive the hinged rod of the rotating shielding plate 63 to rotate. The rotating shielding plate 63, the inclined rod 68, and the connecting rod 610 are provided in two groups, and are symmetrical with the central symmetry axis of the side surface of the fixed shielding plate 62, and are symmetrically distributed on the left and right sides of the fixed shielding plate 62. The cutter 5 can be protected more completely, and the two rotating shielding plates 63 can be opened and closed at the same time. The end of the connecting rod 610 away from the inclined rod 68 is hinged at the eccentric point of the hinge rod of the rotating shielding plate 63, which can enable the inclined rod 68 to push the connecting rod 610 to rotate the rotating shielding plate 63.

[0027] The cleaning mechanism 7 comprises: a hollow block 71, a rotating rod 72, a cleaning rod 73, a connecting rod 74, a first slider 75, a slide groove 76, an extrusion spring 77, a second slider 78, a first hinge rod 79, a telescopic rod 710, and a second hinge rod 711. The back of the hollow block 71 is fixedly mounted on the front of the placement table 2 for easy installation of the rotating rod 72. The rotating rod 72 is rotatably mounted at the hollow of the hollow block 71 for easy installation of the cleaning rod 73. The cleaning rod 73 is fixedly mounted on the top of the rotating rod 72 for easy installation of a brush, which can clean the placement table 2. The connecting rod 74 is hinged at the eccentric position of the bottom of the rotating rod 72 to push the rotating rod 72 to rotate. The end of the connecting rod 74 away from the rotating rod 72 is hinged to the first slider 75 to push the connecting rod 74. A slide groove 76 is provided on the front of the placement table 2 to facilitate the sliding of the first slider 75 and the second slider 78.

[0028] Working principle: at the end of cutting, the cylinder 3 drives the piston rod 4 to move upward, so that the cutter 5 can be retracted to the top. The cutter 5 will not rise to the top during cutting. When moving, the top of the cutter 5 will squeeze the push rod 66 to move upward in the cross slot 64, and the return spring 65 is stretched. When the push rod 66 moves upward, the squeezing rod 67 will move upward, so that the inclined rod 68 is squeezed to move to both sides, and the moving spring 69 is compressed, so that the connecting rod 610 pushes the hinged rod of the rotating baffle 63 to rotate, which can make the rotating baffle 63 rotate and protect the cutter 5. When the cutter 5 moves downward, the moving spring 69 will drive the inclined rod 68 to reset, and the return spring 65 will drive the push rod 66 to reset, so that the rotating baffle 63 can be opened, which can prevent the cutter 5 from being hit by objects and damaged.

[0029] When the baffle plate 63 is rotated to be closed, the second hinged rod 711 can squeeze the telescopic rod 710, so that the telescopic rod 710 drives the first hinged rod 79 to push the second slider 78 to move inside the slide groove 76. After moving a certain distance, the first slider 75 will be squeezed to move, and the squeezing spring 77 is compressed. When the first slider 75 slides, it will drive the connecting rod 74 to push the rotating rod 72 to rotate, so that the cleaning rod 73 rotates, so that the brush at the bottom of the cleaning rod 73 can clean the surface of the placement table 2. When the baffle plate 63 is rotated to be opened, the second hinged rod 711 will drive the first hinged rod 79 through the telescopic rod 710 to make the second slider 78 return to its initial position, and the squeezing spring 77 is reset, so that the first slider 75 is reset, and at the same time the cleaning rod 73 is restored to its initial position to prevent cutting debris from being on the placement table 2 and affecting the accuracy of the next cutting.

[0030] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
