DETAILED DESCRIPTION

[0019] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.

[0020] like Figure 1-4 As shown, a limit baffle for a battery tab cutting brush device comprises: a workbench 1, a plurality of protective shells 2 are placed on the upper end surface of the workbench 1, an opening is arranged at the upper end of the protective shell 2, and a fixed frame 4 is fixedly arranged on the upper end surface of the workbench 1.

[0021] Multiple positive plates and multiple negative plates are placed inside the protective shell 2. The multiple positive plates and multiple negative plates fill the interior of the protective shell 2. A partition is arranged between the positive plates and the negative plates. The partition is used to prevent the positive and negative plates from contacting each other. Battery tabs are connected to the positive and negative plates. The battery tabs form two parallel rows inside the protective shell 2. Both sides of the protective shell 2 are fixedly connected with a placement plate 3.

[0022] The fixing frame 4 is provided with a plurality of parallel notches 5 , the number of which is the same as the number of the protective shells 2 , and a rectangular opening is provided at a position corresponding to each notch 5 on the workbench 1 , and the notches 5 are connected to the rectangular openings.

[0023] A cutting device is fixedly arranged on the lower end surface of the workbench 1 near one side. The number of the cutting devices is the same as the number of the protective shells 2. The cutting device includes a first cylinder 7, which is fixedly arranged on the lower end surface of the workbench 1. A cutting knife 8 is fixedly connected to the output end of the first cylinder 7.

[0024] A grinding device is arranged at a position near the other side of the lower end surface of the workbench 1. The number of the grinding devices is the same as the number of the protective shells 2. The grinding device includes a second cylinder 9. An electric push rod is arranged on the back of the second cylinder 9. The telescopic end of the electric push rod is connected to the second cylinder 9. The second cylinder 9 is slidingly connected to the lower end surface of the workbench 1. The output end of the second cylinder 9 is fixedly connected to the protective shell. A motor 10 is fixedly arranged inside the protective shell. The output shaft of the motor 10 passes through one side of the protective shell and is fixedly connected to a roller brush 11. The length of the roller brush 11 matches the combined length of all the battery poles in each row.

[0025] When the battery tabs need to be cut or polished, a mechanical device is first used to fix and move the multiple protective shells 2 together until the protective shells 2 correspond to the notches 5. The mechanical device then rotates the protective shells 2 180° so that the battery tabs face the notches 5. The mechanical device moves the protective shells 2 downward until the placement plate 3 contacts the lower end surface of the fixing frame 4. The mechanical device then releases the protective shells 2. Figure 2 As shown; start the first cylinder 7, the output end of the first cylinder 7 drives the cutting knife 8 to move to the left, and cuts the uneven length parts of the battery ears. After cutting, the first cylinder 7 drives the cutting knife 8 to return to its original position, start the second cylinder 9, and the second cylinder 9 drives the motor 10 to move to the right until the length of the roller brush 11 covers all the battery ears in one row, start the motor 10, and the output shaft of the motor 10 drives the roller brush 11 to rotate, and grind one side of the battery ears in one row. After grinding, the second cylinder 9 drives the roller brush 11 to return to its original position, start the electric push rod, and the telescopic end of the electric push rod drives the second cylinder 9 to move back and forth to grind the other side of the battery ears in one row. After grinding, the second cylinder 9 drives the roller brush 11 to return to its original position, start the electric push rod again, and the telescopic end of the electric push rod drives the second cylinder 9 to move, and grinds the battery ears in another row.

[0026] In order to prevent the cutting knife 8 and the roller brush 11 from touching the positive and negative battery plates and causing damage thereto when cutting and grinding the battery tabs: a limit baffle is fixedly arranged on the lower end surface of the workbench 1 and at the position of each notch 5, and the limit baffle includes two limit plates 14, and the two limit plates 14 are symmetrically arranged on both sides of the notch 5. The upper end surfaces of the limit plates 14 are fixedly connected to the lower end surface of the workbench 1, and an elastic plate 6 is installed between the positions of the two limit plates 14 near the lower ends. Two protruding portions 61 are fixedly connected to both sides of the elastic plate 6, and the size of the protruding portion 61 is smaller than the end size of the elastic plate 6. The protruding portion 61 penetrates the limit plate 14 and extends to the outside of the limit plate 14, and the protruding portion 61 is integrally formed with the elastic plate 6.

[0027] The elastic plate 6 is provided with a plurality of fixing openings 62 , and the plurality of fixing openings 62 are arranged in two rows.

[0028] When the protective shell 2 falls, the lower part of the protective shell 2 is located inside the limiting device, and the battery tabs pass through the fixing openings 62, so that the cutting knife 8 and the second cylinder 9 can only touch the battery tabs and the limiting device without contacting the positive and negative plates.

[0029] In order to ensure that the battery lugs do not shake during cutting and grinding, the size of the fixing opening 62 needs to be adapted to the size of the battery lugs: the lower end surface of the workbench 1 and the positions on both sides of the notch 5 are fixedly connected with a fixing plate 12, and the fixing plate 12 is threadedly connected with a screw 13, and the end of the screw 13 close to the notch 5 abuts against the protruding portion 61.

[0030] When the battery pole ear is inside the fixing opening 62, the screw 13 is rotated to move toward the elastic plate 6. The screw 13 squeezes the elastic plate 6 by continuously squeezing the protruding portion 61, so that the size of the fixing opening 62 of the elastic plate 6 gradually decreases until the inner wall of the fixing opening 62 squeezes the battery pole ear and fixes it.

[0031] Working principle:

[0032] When the protective shell 2 falls, the lower part of the protective shell 2 is located inside the limiting device, and the battery tabs pass through the fixing openings 62, so that the cutting knife 8 and the second cylinder 9 can only touch the battery tabs and the limiting device without contacting the positive and negative plates.

[0033] When the battery pole ear is inside the fixing opening 62, the screw 13 is rotated to move toward the elastic plate 6. The screw 13 squeezes the elastic plate 6 by continuously squeezing the protruding portion 61, so that the size of the fixing opening 62 of the elastic plate 6 gradually decreases until the inner wall of the fixing opening 62 squeezes the battery pole ear and fixes it.

[0034] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
