[0002] The blade battery case is named after its blade-like shape. Its shape is actually rectangular and is an important part of the blade battery. During the rectangular battery case molding process, the battery case interface needs to be welded together by high-frequency welding. After welding, the surface will be uneven and there will be weld scars and burrs, so scar removal must be performed. Otherwise, the dimensional accuracy of the battery case cannot be guaranteed, and it is difficult to meet the assembly requirements of the blade battery. The existing rectangular battery case is often manually scar-removed, but its dimensional accuracy cannot be guaranteed. Summary of the invention

[0006] Preferably, the scar removal mechanism also includes a second scar removal component, which is identical to the first scar removal component and is symmetrically arranged on a "T"-shaped frame on the upper part of the base, so that two scar removal components can work simultaneously, resulting in higher scar removal efficiency.

[0007] Preferably, the first righting wheel and the second righting wheel are rotatably mounted on the base via a rotating shaft fixed thereto, respectively, the rotating shaft passes through and supports the first righting wheel and the second righting wheel, the lower end of which is rotatably supported by the base and is threadedly connected to the end cover, and the upper end of which is threadedly connected to the handle. The arrangement of the handle and the end cover can prevent the first righting wheel and the second righting wheel from moving up and down, thereby better righting the rectangular battery shell, and the righting wheels can be easily disassembled and assembled by loosening the handle.

[0008] Preferably, the second scar removal component is arranged at the side of the second righting wheel component, and the scar of the rectangular battery shell near the second righting wheel component can be removed more quickly by the second scar removal component.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-4 As shown, a rectangular battery shell weld scar removal device includes a base 1, a scar removal mechanism 2 and a straightening mechanism 3.

[0022] The scar removal mechanism 2 and the straightening mechanism 3 are installed on the machine base 1.

[0023] The scar removal mechanism 2 includes a first scar removal component and a second scar removal component, and the first scar removal component and the second scar removal component are used to perform two scar removal operations on the rectangular battery shell 4 respectively, so that the scar removal effect is better and the size accuracy requirements of the rectangular battery shell are guaranteed.

[0024] The first scar removal component includes a cylinder 201, a tool mounting plate 202 and a tool 203. The cylinder 201 is installed on the machine base 1, and its piston rod is connected to the tool mounting plate 202. The tool 203 is installed on the tool mounting plate 202. The tool 203 can be driven to move up and down by the extension and retraction of the piston rod. When the piston rod is extended, the tool is located at the scar removal position.

[0025] In order to make the tool move up and down smoothly, a slider and rail guide mechanism is provided between the tool mounting plate 202 and the machine base 1 . The rail 204 is mounted on the machine base 1 , and the slider 205 is mounted on the tool mounting plate 202 .

[0026] The second scar removal assembly has the same structure as the first scar removal assembly, and the two are symmetrically arranged relative to the "T"-shaped frame 101 on the upper part of the base 1.

[0027] The straightening mechanism 3 includes a group of straightening wheel assemblies respectively arranged near the first scar removal assembly and the second scar removal assembly. The rectangular battery shell 4 is clamped by the two groups of straightening wheel assemblies to ensure that the rectangular battery shell will not shake during scar removal.

[0028] The group of righting wheel assemblies includes a first righting wheel 301 and a second righting wheel 302. The first righting wheel 301 and the second righting wheel 302 have the same appearance and are both "I"-shaped. They are rotatably supported by the base 1 and are relatively arranged on both sides of the rectangular battery shell 4. The rectangular battery shell 4 can pass through the middle of the first righting wheel 301 and the second righting wheel 302 and play a supporting role.

[0029] The first righting wheel 301 and the second righting wheel 302 are rotatably mounted on the base 1 via a rotating shaft 303 fixed thereto, respectively. The present embodiment uses a key connection to fix the two together, which is convenient for assembly and disassembly. The rotating shaft 303 is inserted into the first righting wheel 301 and the second righting wheel 302, and its lower end is rotatably supported by the base 1 and is threadedly connected to the end cover 305, and its upper end is threadedly connected to the handle 304. The arrangement of the handle 304 and the end cover 305 can prevent the first righting wheel 301 and the second righting wheel 302 from moving up and down, thereby better righting the rectangular battery shell 4.

[0030] Meanwhile, when too much welding slag falls from the welding scar removal around the first and second righting wheels 301 and 302 and needs to be cleaned, the first and second righting wheels 301 and 302 can be easily removed by simply loosening the handle 304, saving time and effort.

[0031] In order to enable the first scar removal component and the second scar removal component to better perform the scar removal function, the upper and lower positions and angles of the cutter 203 can also be adjusted.

[0032] The up and down position adjustment of the tool 203 is achieved through an up and down adjustment mechanism, which includes an adjustment shaft 206 with a handle, a limit block 208, and a guide mechanism. The adjustment shaft 206 is threadedly connected to the upper end of the piston rod of the cylinder 201 as a whole. The adjustment shaft 206 passes through the limit block 208 and is threadedly connected to the limit block 208. The adjustment shaft 206 has a handle to facilitate the rotation of the adjustment shaft 206. The guide mechanism includes a guide shaft 207 and a guide sleeve 2071. The guide sleeve 2071 is fixed in the limit block 208. One end of the guide shaft 207 is fixed on the "T" frame 101 of the machine base 1, and the other end passes through the guide sleeve 2071.

[0033] When the up and down position of the tool needs to be adjusted, the adjustment shaft 206 is rotated forward or backward, and the distance between the stop block 208 and the "T" frame 101 will become smaller or larger. When the desired position is reached, the rotation can be stopped, and then the adjustment shaft 206 is tightened by the locking screw 2081 to prevent relative movement between the adjustment shaft 206 and the stop block 208. When the piston rod of the cylinder 201 extends downward, the stop block 208 is driven downward together. When the bottom of the stop block 208 touches the upper part of the "T" frame 101, the piston rod is prevented from continuing to descend. At this time, the position where the tool stops is the position required for scar removal.

[0034] The angle adjustment of the tool 203 is achieved through an angle adjustment mechanism, which includes a rotating plate 2021, which is rotatably mounted on the tool mounting plate 202 by means of a fixing screw 2022, and the tool 203 is mounted on the rotating plate 2021. When the fixing screw 2022 is loosened, the rotating plate 2021 can be rotated, which also drives the tool to rotate together. After the tool 203 rotates to a desired angle, the fixing screw 2022 is tightened to fix the rotating plate 2021 and determine the angle of the tool 203. If the rotating plate 2021 is too long and the positioning is not stable enough, a second screw hole (not shown in the figure) can be provided at a second position of the rotating plate 2021, and the rotating plate 2021 and the tool mounting plate 202 can be well fixed together by the second screw to prevent the position of the tool from changing.

[0035] The angle adjustment mechanism can also be: adding a fixed block 2023, the fixed block 2023 is installed on the tool mounting plate 202, and a limit screw 2024 is set on it, the limit screw 2024 is unscrewed from the fixed block 2023, and pressed against the rotating plate 2021, so that when adjusting the angle of the rotating plate 2021, the angle of the rotating plate 2021 can be adjusted more quickly by adjusting the limit screw 2024.
