However, lithium batteries may not be able to store and release electrical energy normally due to various reasons in daily use, so the lithium batteries need to be repaired.
[0003] When repairing a lithium battery cell, tools are needed to disassemble the cell. There is a metal ball inside the cell, which is used to control the flow during the cell injection process and prevent liquid leakage after the injection is completed. When disassembling, a soldering iron is needed to be inserted into the injection nozzle to contact and weld the metal ball, and then the metal ball is pulled out. However, during this operation, the soldering iron is prone to relative displacement with the cell, causing the end of the soldering iron to contact and squeeze the expansion of the injection nozzle, thereby affecting the roundness of the expansion hole and causing the cell to be scrapped due to the out-of-round drilling.

DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1 to Figure 2 As shown, a battery core ball removal and rework positioning fixture described in an embodiment of the utility model comprises a base plate 1; a fixing plate 12 is fixedly connected to the top of the base plate 1; a sliding groove 13 is provided on the side wall of the fixing plate 12; a pair of clamping plates 14 are slidably connected to the side wall of the fixing plate 12; a pair of screw sleeves 15 are slidably connected inside the sliding groove 13; a bolt 16 is threadedly connected to the middle part of the screw sleeve 15; the middle part of the bolt 16 passes through the clamping plate 14; when working, the pair of clamping plates 14 are slid to adjust the spacing between the pair of clamping plates 14 to correspond to the width of the battery core, and then the bolts are turned 16 reduces the distance between the bolt 16 and the screw sleeve 15, and then fixes the clamping plate 14 to the side wall of the fixing plate 12, and then places the battery cell from which the metal ball needs to be removed in the middle of a pair of clamping plates 14, and then uses an electric soldering iron to remove the metal ball inside the battery cell. At this time, due to the obstruction of the pair of clamping plates 14, it is difficult for the battery cell to swing left and right between the pair of clamping plates 14, thereby reducing the relative movement between the electric soldering iron and the battery cell hole. Through the above structure, the occurrence of contact and extrusion between the electric soldering iron and the hole can be reduced, thereby reducing the occurrence of battery cell drilling out of roundness and scrapping.
[0023] like Figures 1 to 3As shown, a slide seat 2 is fixed to the top of the base plate 1; a support rod 21 is slidably connected to the top of the slide seat 2; a support plate 22 is slidably connected to the middle of the support rod 21; an electric soldering pen 23 is slidably connected to the middle of the support plate 22; during operation, after the battery cell is clamped by a pair of clamps 14, the bottom end of the electric soldering pen 23 can be aligned with the hole at the top of the battery cell by sliding the support rod 21 and the support plate 22, so that the end of the electric soldering pen 23 can accurately enter the inside of the battery cell hole when it descends, and at the same time, due to the presence of the support rod 21 and the support plate 22, the shaking of the electric soldering pen 23 during operation can be reduced. Through the above structure, the shaking of the electric soldering pen 23 can be reduced when the metal ball inside the battery cell is taken out, and the occurrence of contact and extrusion between the electric soldering iron and the hole can be further reduced.
[0024] like Figures 1 to 4 As shown, a through slot 3 is provided in the middle of the support plate 22; an extrusion block 31 is slidably connected to the middle of the through slot 3; the extrusion block 31 is arranged at one end of the through slot 3 close to the soldering pen 23; a first spring 32 is installed in the middle of the through slot 3; an adjustment block 33 is slidably connected to the end of the through slot 3 away from the extrusion block 31; the side wall of the adjustment block 33 is fixedly connected to the end of the first spring 32; a connecting rod 34 is fixedly connected to the side wall of the adjustment block 33; the other end of the connecting rod 34 is rotatably connected to the side wall of the extrusion block 31; when working, the adjustment block 33 is in the first spring 32 The adjusting block 33 is pulled and squeezed toward the inside of the through slot 3, thereby pushing the squeezing block 31 to squeeze the middle part of the soldering pen 23, so that the soldering pen 23 will not slide easily in the middle part of the support plate 22. When the soldering pen 23 is needed to remove the metal ball, the adjusting block 33 is pulled out of the through slot 3 and rotated, so that the adjusting block 33 can no longer slide into the through slot 3. At the same time, the squeezing block 31 no longer squeezes the soldering pen 23, so that the soldering pen 23 can slide freely in the middle part of the support plate 22. Through the above structure, the occurrence of the soldering pen 23 slipping and damaging the battery core can be reduced.
[0025] like Figure 1 to Figure 2 As shown, a plurality of second springs 4 are fixedly connected to the bottom of the clamping plate 14; a supporting plate 41 is fixedly connected to the top of the plurality of second springs 4; during operation, when the battery cell is placed between a pair of clamping plates 14, the battery cell will fall on the top of the pair of supporting plates 41, and at this time, the supporting plate 41 and the second spring 4 will absorb the impact force of the falling battery cell. Through the above structure, the damage to the bottom of the battery cell due to the falling impact can be reduced.
[0026] like Figure 1 to Figure 2As shown, the opposite side walls of the pair of clamps 14 are each provided with a mounting groove 5; the middle of the mounting groove 5 is slidably connected with a spring sheet 51; during operation, after the battery cell is placed between the pair of clamps 14, the battery cell will squeeze the spring sheet 51, so that the pair of spring sheets 51 clamp and fix the battery cell, and the presence of the pair of spring sheets 51 can make the distance between the pair of supporting plates 41 slightly larger than the width of the battery cell, so that the battery cell can be conveniently placed between the pair of clamps 14, reducing the scratches between the edges of the pair of clamps 14 and the battery cell, thereby reducing the damage to the surface of the battery cell.
[0027] like Figure 1 to Figure 2 As shown, the side wall of the clamping plate 14 away from the fixed plate 12 is fixedly connected with a guide plate 6; a pair of opposite side walls of the clamping plates 14 are fixedly connected with a placement plate 61; during operation, when it is necessary to place the battery cell between the pair of clamping plates 14, the battery cell is first placed above the placement plate 61, and then pushed from between the pair of guide plates 6 toward the inside of the pair of clamping plates 14, thereby reducing the occurrence of scratches on the surface of the battery cell caused by the edge of the clamping plate 14, and further reducing the possibility of damage to the surface of the battery cell.
[0028] like Figure 3 As shown, a plurality of fixing rings 7 are fixedly connected to the top of the support rod 21; the plurality of fixing rings 7 are arranged in parallel; when working, the power cord of the electrocautery pen 23 is passed through the plurality of fixing rings 7 to reduce the influence of the power cord on the operator when operating.
[0029] During operation, the pair of clamping plates 14 are slid to adjust the spacing between the pair of clamping plates 14 to correspond to the width of the battery cell, and then the bolt 16 is turned to reduce the distance between the bolt 16 and the screw sleeve 15, and then the clamping plate 14 is fixed to the side wall of the fixing plate 12, and then the battery cell that needs to be removed from the metal ball is placed in the middle of the pair of clamping plates 14, and then the electric soldering iron is used to remove the metal ball inside the battery cell. At this time, due to the obstruction of the pair of clamping plates 14, it is difficult for the battery cell to swing left and right between the pair of clamping plates 14, thereby reducing the relative movement between the electric soldering iron and the battery cell hole. After the clamping plate 14 clamps the battery cell, the bottom end of the soldering pen 23 can be aligned with the hole on the top of the battery cell by sliding the support rod 21 and the support plate 22, so that the end of the soldering pen 23 can accurately enter the inside of the battery cell hole when it is lowered. At the same time, due to the existence of the support rod 21 and the support plate 22, the shaking of the soldering pen 23 during operation can be reduced. The adjustment block 33 will be squeezed toward the inside of the through groove 3 under the pull of the first spring 32, and then the squeezing block 31 will be pushed to squeeze the middle part of the soldering pen 23, so that the soldering pen 23 will not easily slip in the middle part of the support plate 22. When the soldering pen 23 is needed to remove the metal ball, the adjusting block 33 is pulled out of the through slot 3 and rotated so that the adjusting block 33 can no longer slide into the through slot 3. At the same time, the squeezing block 31 no longer squeezes the soldering pen 23, so that the soldering pen 23 can slide freely in the middle of the support plate 22. When the battery cell is placed between the pair of clamps 14, the battery cell will fall on the pair of supporting plates 41. At this time, the supporting plate 41 and the second spring 4 will absorb the impact force of the battery cell falling. After the battery cell is placed between the pair of clamps 14, the battery cell will hit the shrapnel. 51 is squeezed, so that the pair of spring plates 51 clamps and fixes the battery cell, and the existence of the pair of spring plates 51 can make the distance between the pair of supporting plates 41 slightly larger than the width of the battery cell, so that the battery cell can be conveniently placed between the pair of clamping plates 14, thereby reducing the scratches between the edges of the pair of clamping plates 14 and the battery cell. When the battery cell needs to be placed between the pair of clamping plates 14, the battery cell is first placed above the placement plate 61, and then pushed from between the pair of guide plates 6 toward the inside of the pair of clamping plates 14, thereby reducing the scratches on the surface of the battery cell caused by the edges of the clamping plates 14.
