However, the connection design between the blade of the rubber cutting device and the slide cylinder is unreasonable, and the blade is prone to shaking and shifting during use, affecting the effect of the rubber cutting. Therefore, it is very necessary to provide a reliable and safe rubber cutting device. Utility Model Content

[0018] The following will be combined with the drawings in 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 in 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.

[0019] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0020] See also Figure 1-4In this embodiment, the battery cell 4 is surrounded by insulating glue 5, and a circle of insulating glue of a certain length is reserved on the top of the battery. A lithium battery cell insulating glue cutting device includes a blade 1, a slide cylinder 2 and a tool holder 3, wherein the slide cylinder 2 includes a cylinder guide rail 21 and a fixed block 22 connected to the cylinder guide rail 21, and the tool holder 3 is fixedly connected to the fixed block 22. The blade 1 is fixed on the tool holder 3 so that the blade 1 can move horizontally along the guide rail direction to achieve glue cutting. The tool holder 3 includes a first plate 31 and a second plate 32 supported on both sides of the blade 1. The first plate 31 has a groove 311 on the inner side, and the second plate 32 has a boss 321 on the inner side. The blade 1 is placed in the groove 311 and then tightened by the boss 321. The first plate 31, the blade 1, and the second plate 32 are connected by a through fastener. The groove 311 and the boss 321 cooperate with each other to make the connection between the blade 1 and the blade holder 3 more stable. In addition, the fasteners can prevent the blade 1 from shaking and shifting due to external forces during the rubber cutting process.

[0021] Furthermore, the first plate 31 includes a connecting plate 312 and a baffle 313 connected to the connecting plate 312 . The baffle 313 abuts against an edge of the second plate 32 to provide a certain supporting force during the transverse rubber cutting process.

[0022] Furthermore, the first plate 31 also includes an L-shaped plate 314 integrally connected to one side of the baffle 313, and the inner side of the L-shaped plate 314 is covered on a corner of the fixing block 22, and the two are connected and fixed by bolts to ensure the reliability of the connection between the first plate 31 and the fixing block 22.

[0023] Furthermore, there are two blades 1, and the cutting edges of the two blades 1 face outwards and can move in parallel with each other.

[0024] Furthermore, the blade back of the blade 1 is wedge-shaped, which saves material and reduces weight.

[0025] When the utility model is in use, the slide cylinder 2 moves downward, so that the blade 1 descends and extends into the insulating glue 5, and the cylinder slide rail 22 drives the left and right blades 1 to slide to both sides to cut the edges of the insulating glue 5 on the top of the battery cell 4. After the stroke is completed, the blade is reset, and the slide cylinder 2 moves upward. The cut insulating glue 5 is folded downward to cover the top of the battery.
