Description

Technical Field

[0001] The invention relates to the technical field of battery recycling, and in particular to a battery shell cutting device. Background Art

[0002] As the core component of new energy vehicles, batteries are mainly responsible for storing and supplying driving electricity. With their widespread use, the recycling of used batteries has become more and more prominent. In the recycling process of used batteries, cutting the battery shell is a key step. It usually occurs in the disassembly stage of battery recycling. The main purpose of cutting the battery shell is to separate the battery shell from the internal battery cell so that the battery cell and the battery shell can be processed separately later. This is because the battery shell is mostly made of metal (such as aluminum alloy) and the battery cell is rich in valuable metal elements such as nickel, cobalt, and manganese, so they need to be recycled and processed separately. However, there are many types and varieties of batteries on the market, and the sizes of batteries of different models vary greatly, so cutting equipment cannot be used for different models of batteries.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-Figure 5As shown, a battery shell cutting device in this embodiment includes a frame 1, a cutting assembly 2, a clamping and positioning assembly 3, and an auxiliary positioning assembly 4; the frame 1 includes an upper platform 101 and a lower platform 102 arranged on the lower side of the upper platform 101; The clamping and positioning assembly 3 includes a gantry 301 disposed on the upper platform 101 and a first driving element 302 disposed on the gantry 301, a clamping and positioning block 303 is disposed on the output shaft of the first driving element 302, and the output shaft of the first driving element 302 can drive the clamping and positioning block 303 to move in the up and down directions, so that the clamping and positioning block 303 is close to or away from the upper platform 101; The auxiliary positioning assembly 4 includes a second driving element 401 disposed on the upper platform 101, and an auxiliary positioning block 402 is disposed on the output shaft of the second driving element 401. The output shaft of the second driving element 401 can drive the auxiliary positioning block 402 to move in the front-rear direction, so that the auxiliary positioning block 402 is close to or away from the gantry 301; The cutting assembly 2 is disposed on the lower platform 102 . After the clamping and positioning assembly 3 and the auxiliary positioning assembly 4 fix the battery shell, the cutting assembly 2 can cut the battery shell.

[0020] The auxiliary positioning block 402 is used to contact the side of the battery and push the battery to move to a predetermined position, so as to facilitate the subsequent cutting of the battery shell. The clamping positioning block 303 is used to press and fix the battery that has reached the predetermined position on the upper platform 101 to prevent the battery from moving during the subsequent cutting process. There are large differences in the sizes of batteries of different models, and the cutting positions of batteries of different models are also different. Since the output shaft of the second driving element 401 can drive the auxiliary positioning block 402 to move, the movement stroke of the output shaft of the second driving element 401 can be adjusted to achieve the desired predetermined position for batteries of different models, and since the output shaft of the first driving element 302 can drive the clamping positioning block 303 to move, the movement stroke of the output shaft of the first driving element 302 can be adjusted to achieve the clamping and positioning of batteries of different models. Through the cooperation of the clamping positioning component 3 and the auxiliary positioning component 4, the battery shell cutting device is suitable for batteries of different sizes, which enhances the flexibility and versatility of the device. In addition, the battery shell cutting device is easy to operate, saving time and effort.

[0021] In this embodiment, the upper platform 101 is provided with a through groove 103 with a length along the left-right direction, and the through groove 103 is through in the up-down direction; the cutting assembly 2 includes a driving mechanism, a movable seat 204 and a cutting motor 206, and the driving mechanism can drive the movable seat 204 to reciprocate along the left-right direction on the lower platform 102, and the cutting motor 206 is arranged on the movable seat 204. A cutting wheel piece 207 is arranged on the output shaft of the cutting motor 206, and a part of the cutting wheel piece 207 extends upward from the through groove 103.

[0022] The upper part of the cutting wheel 207 extends out of the through slot 103. When the cutting motor 206 moves in the left and right directions, the battery casing can be cut by the extended part of the cutting wheel 207. Most of the cutting wheel 207 is located between the upper platform 101 and the lower platform 102, reducing the risk of operator injury due to misoperation.

[0023] In this embodiment, the clamping positioning component 3 and the auxiliary positioning component 4 are respectively located on different sides of the through groove 103, and the output shaft of the second driving element 401 can drive the auxiliary positioning block 402 to move in the front and rear directions so that the auxiliary positioning block 402 is close to or away from the through groove 103.

[0024] The positions of the clamping and positioning assembly 3 and the auxiliary positioning assembly 4 are staggered from the through slot 103 , which can prevent the cutting wheel 207 from interfering with the clamping and positioning assembly 3 or the auxiliary positioning assembly 4 .

[0025] In this embodiment, the driving mechanism includes a fixed seat 201 disposed on the lower platform 102 and a driving motor 202 disposed on the fixed seat 201, a lead screw body 203 is disposed on the fixed seat 201, a nut seat 205 is disposed at the bottom of the movable seat 204, the lead screw body 203 and the nut seat 205 cooperate to form a ball screw nut pair, and the driving motor 202 can drive the lead screw to rotate so that the movable seat 204 reciprocates in the left and right directions on the lower platform 102. The ball screw nut pair can convert the rotational motion of the driving motor 202 into the linear motion of the nut seat 205 and the movable seat 204, and the motion is stable and reliable.

[0026] In this embodiment, two protective covers 104 are provided on the upper platform 101. The two protective covers 104 are respectively located on the left and right sides of the gantry 301. The two protective covers 104 cover the upper part of the through groove 103, and a relief cavity for the cutting wheel blade 207 to pass through is formed inside the two protective covers 104. The motor is fixed between the two support rods 3012 of the gantry 301, and the position of the housing of the cutting motor 206 is also between the two support rods 3012 of the gantry 301. Therefore, the remaining positions can cover the through groove 103 through the protective cover 104, and when the cutting wheel blade 207 moves to these positions, it is also covered by the protective cover 104, reducing the risk of injury to the operator due to misoperation.

[0027] In this embodiment, both of the two protective covers 104 are in a "Ji" shape. The two legs of the "Ji" shape structure are fixedly connected to the upper platform 101, and the inner cavity of the "Ji" shape structure can be used as a relief cavity for the cutting wheel blade 207 to pass through.

[0028] In this embodiment, the gantry 301 includes two reinforcing rods 3011, two support rods 3012 and an installation rod 3013. The two reinforcing rods 3011 are fixedly connected to the upper platform 101. The positions of the two reinforcing rods 3011 are both offset from the through groove 103. The front ends of the two reinforcing rods 3011 are respectively connected to the lower ends of the two support rods 3012, and the upper ends of the two support rods 3012 are respectively connected to the left and right ends of the installation rod 3013. The gantry 301 is used to raise the height of the first driving element 302, so that there is a space for placing the battery between the clamping and positioning block 303 and the upper platform 101. The reinforcing rod 3011 can increase the stability of the gantry 301.

[0029] In this embodiment, at least two first driving elements 302 are provided, and the first driving elements 302 are arranged at intervals in the left-right direction on the installation rod 3013. In this embodiment, the number of the second driving elements 401 is the same as the number of the first driving elements 302, and the positions of the second driving elements 401 in the left-right direction respectively correspond to the positions of the first driving elements 302 in the left-right direction one by one.

[0030] One first driving element 302 and the corresponding second driving element 401 can fix one battery. The first driving elements 302 and the second driving elements 401 are both provided in two or more numbers, and two or more batteries can be fixed simultaneously. During the process of the cutting motor 206 moving along the left-right direction, the outer shells of the respective batteries can be cut in sequence, significantly improving the cutting efficiency.

[0031] In this embodiment, the frame 1 further includes a frame structure 105 composed of a plurality of beams, the upper platform 101 is disposed on the top of the frame structure 105 , and the lower platform 102 is disposed in the middle of the frame structure 105 .

When used, the following steps are included: S1, the output shafts of the first driving element 302 and the second driving element 401 are all in a retracted state. At this time, the clamping positioning block 303 is away from the upper platform 101, and the auxiliary positioning block 402 is away from the gantry 301 and the through slot 103. There is a large space between the clamping positioning block 303, the auxiliary positioning block 402 and the upper platform 101. The operator places the battery in the space, and the side of the battery should be against the auxiliary positioning block 402; S2, the output shaft of the second driving element 401 is extended to make the auxiliary positioning block 402 move toward the direction close to the through slot 103, and the movement of the auxiliary positioning block 402 will simultaneously push the battery to move until the battery moves to a predetermined position, so as to facilitate the subsequent cutting of the battery shell; S3, the output shaft of the first driving element 302 is extended to make the clamping and positioning block 303 move downward, and the clamping and positioning block 303 presses and fixes the battery on the upper platform 101 to prevent the battery from moving during the subsequent cutting process; S4. The lead screw is driven to rotate by the driving motor 202 to make the movable seat 204 move in the left and right direction on the lower platform 102, so that the battery shell can be cut by the cutting wheel 207, so that the battery cell and the battery shell can be separated and recycled separately.
