[0020] In the description of the present invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0022] The following is combined with Figure 1-4 The utility model is further described.

[0023] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a rubber tapping device for lithium battery production.

[0024] The specific technical solution includes a base 1, a mold base 9, a mounting frame 6, and a rotating unit.

[0025] In the specific technical solution, a fixing frame 2 is fixed on the base 1, and support legs are installed around the bottom end of the base 1. An electric push rod 4 is fixed on the fixing frame 2. The fixing frame 2 is a U-shaped structure, and the purpose of the electric push rod 4 is to push the mounting frame 6 to slide. The electric push rod 4 can be replaced by a cylinder or a hydraulic cylinder.

[0026] Further explanation, the mold base 9 is also set at the top of the base 1. Similarly, in order to limit the position of the mold base 9 and facilitate taking it, at least two sets of limiting plates 11 are fixed on the base 1, and the limiting plates 11 are L-shaped structures. In this application, four limiting plates 11 are fixedly set in a rectangular arrangement, which are used to limit and fix the position of the mold base 9, and multiple sets of grooves 10 are provided on the mold base 9 for placing the battery body 16, and the grooves 10 are 1 / 4-1 / 2 circular structures. The grooves 10 in this application are approximately 1 / 2 circular structures.

[0027] Among them, the mounting frame 6 is also arranged below the fixing frame 2, and multiple groups of cutting knives 7 are installed in the mounting frame 6. Specifically, at least two guide rods 14 are fixedly set in the mounting frame 6. In this application, two guide rods 14 are fixedly set for guiding the cutting knife 7. The cutting knife 7 passes through and is slidably connected to the guide rod 14. The top thread of the cutting knife 7 is installed with a positioning bolt 15. The position of the cutting knife 7 is adjusted by sliding, so the position of the cutting knife 7 can be adjusted according to the cutting range requirements. After the adjustment is completed, the positioning bolt 15 is rotated to fix the position of the cutting knife 7. The positioning bolt 15 is fixed in contact with the guide rod 14.

[0028] In order to increase safety, a rotating unit is provided outside the fixing frame 2 to drive the mounting frame 6 to rotate.

[0029] The specific design is as follows

[0030] The rotating unit includes a slide 8 provided on the side wall of the mounting frame 6, a guide block 13 provided in the slide 8, a spring 12 fixedly provided between the guide block 13 and the inner wall of the slide 8, and a rotating rod 5 fixedly installed on the outside of the guide block 13. The guide block 13 is a rectangular parallelepiped structure.

[0031] The rotating rod 5 is rotatably connected to the fixing frame 2 . A motor 3 is fixedly mounted on the outside of the fixing frame 2 . The driving shaft of the motor 3 is fixedly connected to the rotating rod 5 .

[0032] The above technical solution is explained as follows: when there is no need to cut the tape 17, the motor 3 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the guide block 13 to rotate, and then the guide block 13 contacts the side wall of the slide 8, so that the mounting frame 6 can be driven to rotate. After the mounting frame 6 is rotated 90 degrees, the mounting frame 6 drives the cutting knife 7 toward the back, as shown in the attached figure. Figure 2 As shown, there will be no safety hazard (if the cutting knife 7 is directly set downward, there is a risk of scratching when the worker places the battery body 16), and the worker places the battery body 16 in this direction.

[0033] Please refer to the following for details

[0034] Place the battery bodies 16 on the corresponding grooves 10 and arrange them in an array. Figure 1 , and then bonding the tape 17 to the plurality of battery main bodies 16;

[0035] Then start the motor 3 to drive the rotating rod 5 to rotate, and the rotating rod 5 drives the guide block 13 to rotate, and then the guide block 13 contacts the side wall of the slide 8, so that the mounting frame 6 can be driven to rotate. After the mounting frame 6 is rotated 90 degrees, the direction of the cutting knife 7 is downward, as shown in the attached figure. Figure 1 As shown;

[0036] Then start the electric push rod 4 to work, and let the piston rod of the electric push rod 4 push the mounting frame 6 to move downward, so that the slide 8 slides outside the guide block 13 until the mounting frame 6 drives the cutting knife 7 to cut the tape 17.

[0037] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
