The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0054] The utility model provides a processing device for a battery cell tab. A battery comprises a battery cell. The battery cell is formed by stacking a plurality of pole pieces. An insulating film is arranged between adjacent pole pieces to separate the adjacent pole pieces. After the plurality of pole pieces are stacked into a battery cell, the tab needs to be cut and flattened. The processing device of the utility model can cut and flatten the tab.

[0055] Please refer to Figures 1 to 6 The processing equipment includes a mounting bracket 110, a cutting device 111 and a feeding device 120. The mounting bracket 110 can be a substantially rectangular flat plate structure. The mounting bracket 110 is fixedly arranged. The cutting device 111 and the feeding device 120 are both arranged on the mounting bracket 110, so that the mounting bracket 110 supports the cutting device 111 and the feeding device 120.

[0056] like Figure 2 As shown, the loading device 120 includes a cell fixing member 121. The cell fixing member 121 may be a flat plate structure. The cell may be placed on the upper surface of the cell fixing member 121 and fixedly connected to the cell fixing member 121. In this way, the cell fixing member 121 can support the cell.

[0057] like Figure 1 , Figure 3 ,as well as Figure 7 and Figure 8 As shown, the cutting device 111 can cut the tabs of the battery cell. The tabs of the battery cell include a positive tab 181 and a negative tab 182. The cutting device 111 includes a first cutting device 112 and a second cutting device 113. Along the first direction D1, the first cutting device 112, the battery cell fixing member 121 and the second cutting device 113 are arranged in sequence.

[0058] It should be noted that, in this embodiment, the first direction D1 and the second direction D2 are parallel to the horizontal direction. The first direction D1 and the second direction D2 intersect. For example, vertically. The third direction D3 is parallel to the vertical direction. In this way, any one of the first direction D1 and the second direction D2 intersects (for example, vertically) with the third direction D3. Among them, the first direction D1 is parallel to the length direction of the mounting bracket 110, the second direction D2 is parallel to the width direction of the mounting bracket 110, and the third direction D3 is parallel to the vertical direction.

[0059] Please refer to Figure 1 and Figure 2, the battery cell fixing member 121 can rotate horizontally. That is, the rotation axis of the battery cell fixing member 121 is parallel to the third direction D3. In this way, the battery cell fixing member 121 can drive the battery cell to rotate.

[0060] like Figure 7 and Figure 8 As shown, there are two types of battery cells. The two battery cells include a first battery cell 180 (such as Figure 7 as shown) and the second battery cell 183 (as shown Figure 8 As shown). The positive electrode tab 181 (an example of the first tab) and the negative electrode tab 182 (an example of the second tab) of the first battery cell 180 are located at the same end of the battery cell. The positive electrode tab 181 (an example of the first tab) and the negative electrode tab 182 (an example of the second tab) of the second battery cell 183 are respectively located at two ends of the battery cell that are opposite to each other.

[0061] For the first battery cell 180, the first battery cell 180 can be fixed to the battery cell fixing member 121. Then, the positive electrode tab 181 of the first battery cell 180 is placed at the first cutting device 112, and then the positive electrode tab 181 of the first battery cell 180 is cut by the first cutting device 112.

Therefore, at this time, the battery cell fixing member 121 is rotated to rotate the negative electrode tab 182 of the first battery cell 180 to the second cutting device 113, and then the negative electrode tab 182 of the first battery cell 180 is cut by the second cutting device 113.

[0062] For the second battery cell 183, the second battery cell 183 can be fixed to the battery cell fixing member 121. Then, the positive electrode tab 181 of the second battery cell 183 is placed at the first cutting device 112, and then the positive electrode tab 181 is cut by the first cutting device 112. Since the battery cell fixing member 121 is located between the first cutting device 112 and the second cutting device 113 along the first direction D1, and the positive electrode tab 181 and the negative electrode tab 182 of the second battery cell 183 are respectively located at the two ends of the battery cell facing away from each other. Therefore, at this time, there is no need to rotate the battery cell fixing member 121, so that the negative electrode tab 182 of the second battery cell 183 is placed at the second cutting device 113, and then the negative electrode tab 182 is cut by the second cutting device 113.

[0063] In this embodiment, the battery cell fixing member 121 can rotate horizontally, thereby driving the battery cell to rotate, so that the processing equipment can be suitable for cutting different battery cells, and the processing equipment has a wide range of applications.

[0088] Please refer to Figures 3 to 5 After the tab is overlapped to the upper surface of the first cutter 143 , the second cutter 144 is moved downward. In this way, the blowing member 150 reaches the tab before the second cutter 144 , and then presses the tab against the upper surface of the first cutter 143 .

[0089] The second cutter 144 is continuously moved downward until the tab is cut. In this process, the blowing member 150 presses the tab against the upper surface of the first cutter 143. In this way, the tab is prevented from moving and the tab can be cut conveniently.

[0090] like Figure 3 As shown, the cutting device 111 also includes a cutting collection piece 152. The cutting collection piece 152 is fixedly connected to the cutting bracket 140. The cutting collection piece 152 has a collection channel 153 and a collection opening 154. The collection opening 154 is connected to the collection channel 153. The collection opening 154 faces the contact surface between the first cutter 143 and the pole ear. The collection channel 153 can be connected to the negative pressure device through a pipeline. In this way, a negative pressure can be formed in the collection channel 153 to suck in the debris generated when cutting the pole ear.

[0091] Preferably, the cutting and collecting member 152 is a cover-shaped structure. Thus, the cutting and collecting member 152 has a simple structure.

[0092] Furthermore, along the extension direction of the collecting channel 153, the area of ​​the cross section of the collecting channel 153 (the cross section is perpendicular to the extension direction of the collecting channel 153) gradually increases. In this way, the collecting channel 153 is constructed as a gradually expanding structure, and the large end of the gradually expanding structure has a collecting opening 154. As a result, it is more convenient to suck in the debris generated when cutting the tabs. In this article, the extension direction of the channel is the extension direction of the center line of the channel. For example, the extension direction of the circular channel is the extension direction of the axis of the circular channel (the center line of the circular channel).

[0093] Preferably, if Figure 3 As shown, along the first direction D1, the cutting and collecting member 152 is located on the side of the second cutter 144 and the first cutter 143 away from the battery cell fixing member 121. In this way, the collecting opening 154 is located on the side of the first cutter 143 along the horizontal direction. Therefore, the structure of the cutting device 111 is compact.

[0094] Please refer to Figure 1 and Figure 6 The processing equipment further includes a flattening device 114. The flattening device 114 is located on the side of the cutting device 111. The battery cell fixing member 121 can move so that the tab of the battery cell moves to the flattening device 114, and then the flattening device 114 can flatten the tab. Thus, the battery cell whose tab has been cut by the cutting device 111 can move to the flattening device 114 to flatten the tab.

[0095] like Figure 1 As shown, the flattening device 114 includes a first flattening device 115 and a second flattening device 116. Along the first direction D1, the first flattening device 115, the battery cell fixing member 121 and the second flattening device 116 are arranged in sequence. Along the first direction D1, the first flattening device 115 is located at the first cutting device 112, and the second flattening device 116 is located at the second cutting device 113. Along the second direction D2, the first cutting device 112 and the first flattening device 115 are arranged in sequence, and the second cutting device 113 and the second flattening device 116 are arranged in sequence. Along the second direction D2, the first cutting device 112 is located at the second cutting device 113, and the first flattening device 115 is located at the second flattening device 116. Among them, the first flattening device 115 is used to flatten the positive electrode tab 181. The second flattening device 116 is used to flatten the negative electrode tab 182.

[0096] like Figure 6As shown, the leveling device 114 includes a leveling bracket 160, a leveling rail 161 and a leveling block 162. The length direction of the leveling rail 161 extends along the first direction D1. The leveling rail 161 is connected to the mounting bracket 110. The leveling block 162 is connected to the leveling bracket 160. The leveling bracket 160 can move along the first direction D1. The leveling block 162 cooperates with the leveling rail 161 to guide the movement of the leveling bracket 160 along the first direction D1.

[0097] Preferably, if Figure 1 As shown, the screw includes a leveling screw. The leveling screw is threadedly connected to the leveling bracket 160. In this way, by rotating the leveling screw, the leveling bracket 160 can be driven to move along the first direction D1. Specifically, the first leveling device 115 and the second leveling device 116 are respectively connected to two leveling screws. In this way, the first leveling device 115 and the second leveling device 116 can be controlled to move along the first direction D1 respectively. In this way, the first leveling device 115 and the second leveling device 116 can be moved along the first direction D1 to adjust the relative distance between the first leveling device 115 and the second leveling device 116 along the first direction D1 to be suitable for battery cells of different sizes. As a result, the processing equipment has a wide range of applications.

[0098] like Figure 6 As shown, the leveling device 114 further includes a first pressing block 163 and a second pressing block 164. The first pressing block 163 is fixedly disposed on the leveling bracket 160. The second pressing block 164 is movably connected to the leveling bracket 160 along a third direction D3. In this way, the second pressing block 164 can move along the third direction D3 relative to the first pressing block 163. In this way, the second cutter 144 can move between the original pressing block position and the leveling pressing block position.

[0099] In this way, the tab is placed on the upper surface of the first pressing block 163 , and the second pressing block 164 is moved toward the first pressing block 163 , so that the tab can be flattened (flattened).

[0100] like Figure 6 As shown, specifically, the leveling device 114 further includes a leveling movable bracket 165 and a leveling guide column 166. The leveling movable bracket 165 is connected to the second pressing block 164. The leveling movable bracket 165 is movably connected to the leveling bracket 160 along the third direction D3. The leveling bracket 160 is provided with a leveling guide hole.

[0101] The length direction of the leveling guide post 166 extends along the third direction D3. The leveling guide post 166 is connected to the leveling movable bracket 165. The leveling guide post 166 is inserted into the leveling guide hole to cooperate with the leveling guide hole to guide the movement of the leveling movable bracket 165 along the third direction D3. As a result, the movement of the leveling movable bracket 165 along the third direction D3 is more stable.

[0102] Please continue to refer to Figure 6 The leveling device 114 further includes a leveling driving assembly 167. The leveling driving assembly 167 is connected to the leveling bracket 160 and the leveling movable bracket 165 to drive the leveling movable bracket 165 to move along the third direction D3.

[0103] like Figure 6 As shown, the leveling device 114 also includes a leveling collecting piece 168. The leveling collecting piece 168 is fixedly connected to the leveling bracket 160. The leveling collecting piece 168 has a leveling channel 169 and a leveling opening 170. The leveling opening 170 is connected to the leveling channel 169. The leveling opening 170 faces the contact surface between the first pressing block 163 and the tab. The leveling channel 169 can be connected to a negative pressure device through a pipeline. In this way, a negative pressure can be formed in the leveling channel 169 to suck in the debris generated when the tab is leveled.

[0104] Preferably, if Figure 6 As shown, the leveling collection member 168 includes a side arm 171 and an end arm 172. The extension direction of the end arm 172 intersects with the extension direction of the side arm 171. The end arm 172 is connected to the side arm 171. The leveling opening 170 is located at the end arm 172. The internal channel of the side arm 171 is used to connect to the negative pressure device. Therefore, the structure of the leveling collection member 168 is simple.

[0105] Further preferably, there are two side arms 171. The two side arms 171 and the end arm 172 are connected to form a substantially U-shaped structure. The end arm 172 is closer to the first pressing block 163 than the side arm 171. Thus, the structure of the leveling collector 168 is simple.

[0106] Preferably, along the first direction D1, the leveling collector 168 is located on the side of the second pressing block 164 and the first pressing block 163 away from the battery cell fixing member 121. In this way, the leveling opening 170 is located on the side of the first pressing block 163 along the horizontal direction. Therefore, the structure of the leveling device 114 is compact.

[0107] For the first battery cell 180, the method for processing the battery cell by the processing equipment includes a fixing step, a first moving step, a positive electrode cutting step, a second moving step, a negative electrode cutting step, a third moving step, a positive electrode leveling step, a fourth moving step and a positive electrode leveling step.

[0108] The fixing step is to place the first battery cell 180 on the battery cell fixing member 121, and move the pressing member 135 downward to press the first battery cell 180 against the battery cell fixing member 121. At this time, the positive pole tab 181 and the negative pole tab 182 of the first battery cell 180 are located at the same end of the first battery cell 180 along the first direction D1. Along the first direction D1, the first cutting device 112, the first battery cell 180 and the second cutting device 113 are arranged in sequence. The position of the pole tab of the first battery cell 180 is higher than the position of the first cutter 143. At this time, the first battery cell 180 is located at Figure 1 The cell holder 121 is shown (original position).

[0109] The first moving step is to move the battery cell fixing member 121 along the second direction D2 to the first cutting device 112. In this way, along the second direction D2, the first cutting knife 143 of the first cutting device 112 is located at the positive electrode tab 181 of the first battery cell 180. At this time, the battery cell fixing member 121 is located at Figure 1 Along the first direction D1, the battery cell fixing member 121 is located at the middle loading position.

[0110] The positive electrode cutting step includes causing the first cutting device 112 to perform a cutting step to cut the positive electrode tab of the first battery cell 180 .

[0111] The positive electrode cutting step includes a first positive electrode step, a second positive electrode step, a third positive electrode step and a fourth positive electrode step.

[0112] The first positive electrode step is to move the battery cell fixing member 121 from the middle loading position toward the first cutting device 112 to the first loading position along the first direction D1 (at this time, the battery cell fixing member 121 is located at Figure 1 A1 position), so that the positive electrode tab 181 of the first battery cell 180 moves between the first cutter 143 and the second cutter 144 of the first cutting device 112.

[0113] The second positive electrode step is to move the battery cell fixing member 121 downward from the moving position to the cutting position so that the positive electrode tab 181 of the first battery cell 180 overlaps the upper surface of the first cutter 143; and the second cutter 144 moves downward from the original cutter position toward the cutting cutter position. During the downward movement of the second cutter 144, the blowing member 150 first contacts the positive electrode tab 181, and then presses the positive electrode tab 181 against the upper surface of the first cutter 143; and the second cutter 144 continues to move downward toward the cutting cutter position to complete the cutting of the positive electrode tab 181, and then returns to the original cutter position.

[0114] In the third positive electrode step, when the second cutter 144 starts to move from the original cutter position toward the cutting cutter position, the negative pressure device is operated to generate negative pressure in the collection channel 153 of the cutting collection member 152. The negative pressure device is kept in the working state during the process of the second cutter 144 leaving the original cutter position. In this way, the debris generated by cutting the tab can be sucked into the cutting collection member 152.

[0115] In the fourth positive electrode step, when the second cutter 144 starts to return to the original cutter position from the cutting cutter position, the blowing assembly 148 blows air toward the upper surface of the first cutter 143, which can more effectively remove the debris generated by cutting the electrode ear.

[0116] The second moving step is to move the battery cell fixing member 121 along the first direction D1 to the middle loading position (at this time, the battery cell fixing member 121 is located at Figure 1 A3 position); move the battery cell fixing member 121 upward to the moving position; rotate the battery cell fixing member 121 180 degrees so that the second cutting knife 144 of the second cutting device 113 is located at the negative electrode ear 182 of the first battery cell 180.

[0117] The negative electrode cutting step causes the second cutting device 113 to perform the cutting step to cut the negative electrode tab 182 of the first battery cell 180. The second cutting device 113 performs the cutting step to cut the negative electrode tab 182 of the first battery cell 180 in a manner substantially similar to the first cutting device 112 performing the cutting step to cut the positive electrode tab of the first battery cell 180.

[0118] Specifically, the negative electrode cutting step includes a first negative electrode step, a second negative electrode step, a third negative electrode step and a fourth negative electrode step.

[0119] First negative electrode step, the battery cell fixing member 121 moves from the middle loading position toward the second cutting device 113 along the first direction D1 to the second loading position (at this time, the battery cell fixing member 121 is located at Figure 1 A4 position), so that the negative electrode tab 182 of the first battery cell 180 moves between the first cutter 143 and the second cutter 144 of the second cutting device 113.

[0120] The second negative electrode step is to move the battery cell fixing member 121 downward from the moving position to the cutting position so that the negative electrode tab 182 of the first battery cell 180 overlaps the upper surface of the first cutter 143; and the second cutter 144 moves downward from the original cutter position toward the cutting cutter position. In the process of the second cutter 144 moving downward, the blowing member 150 first contacts the positive electrode tab 181, and then presses the negative electrode tab 182 against the upper surface of the first cutter 143; the second cutter 144 continues to move downward toward the cutting cutter position to complete the cutting of the negative electrode tab 182, and then returns to the original cutter position.

[0121] In the third negative electrode step, when the second cutter 144 starts to move from the original cutter position toward the cutting cutter position, the negative pressure device is operated to generate negative pressure in the collection channel 153 of the cutting collection member 152. The negative pressure device is kept in the working state during the process of the second cutter 144 leaving the original cutter position. In this way, the debris generated by cutting the tab can be sucked into the cutting collection member 152.

[0122] In the fourth negative electrode step, when the second cutter 144 starts to return to the original cutter position from the cutting cutter position, the blowing assembly 148 blows air toward the upper surface of the first cutter 143, which can more effectively remove the debris generated by cutting the electrode ear.

[0123] The third moving step is to move the battery cell fixing member 121 upward to the moving position; and to move the battery cell fixing member 121 along the second direction D2 to the flattening position (at this time, the battery cell fixing member 121 is located at Figure 1 At this time, the negative electrode tab 182 of the battery cell moves to between the first pressing block 163 and the second pressing block 164 of the second leveling device 116.

[0124] Positive electrode leveling step, the battery cell fixing member 121 is moved downward from the moving position to the cutting position, so that the negative electrode tab 182 of the battery cell is overlapped to the upper surface of the first pressing block 163; the second pressing block 164 is moved downward from the original pressing block position toward the leveling pressing block position to complete the leveling of the negative electrode tab 182, and then returns to the original pressing block position; when the second pressing block 164 of the second leveling device 116 starts to move downward from the original pressing block position toward the leveling pressing block position, the negative pressure device of the second leveling device 116 is operated to generate negative pressure in the collecting channel 153 of the second leveling device 116. The negative pressure device keeps working during the process of the second pressing block 164 leaving the original pressing block position. In this way, the debris of the leveled tab can be sucked into the leveling collecting member 168.

[0125] The fourth moving step is to move the cell fixing member 121 along the first direction D1 to the middle loading position; move the cell fixing member 121 upward to the moving position; rotate the cell fixing member 121 180 degrees so that the second pressing block 164 of the first leveling device 115 is located at the positive electrode ear 181 of the cell.

[0126] Negative electrode leveling step, moving the cell fixing member 121 from the middle loading position toward the first leveling device 115 to the first loading position along the first direction D1 (at this time, the cell fixing member 121 is located at Figure 1 A2 position), so that the positive electrode tab 181 of the first battery cell 180 moves between the first pressing block 163 and the second pressing block 164 of the first leveling device 115;

[0127] The battery cell fixing member 121 is moved downward from the moving position to the cutting position so that the positive pole ear 181 of the battery cell overlaps the upper surface of the first pressing block 163; the second pressing block 164 is moved downward from the original pressing block position toward the flattening pressing block position to complete the flattening of the positive pole ear 181, and then returns to the original pressing block position; when the second pressing block 164 of the first flattening device 115 starts to move downward from the original pressing block position toward the flattening pressing block position, the negative pressure device of the first flattening device 115 is operated to generate negative pressure in the collecting channel 153 of the first flattening device 115. The negative pressure device keeps working during the process of the second pressing block 164 leaving the original pressing block position. In this way, the debris of the flattened pole ear can be sucked into the flattening collecting member 168.

[0128] The cell fixing member 121 is moved to the middle loading position along the first direction D1; the cell fixing member 121 is moved to the moving position along the third direction D3; and the cell fixing member 121 is moved to the original position along the second direction D2.

[0129] For the second battery cell 183, the positive electrode tab 181 and the negative electrode tab 182 of the battery cell can be cut in sequence without rotating the battery cell fixture 121 by 180°. The positive electrode tab 181 and the negative electrode tab 182 of the battery cell can be flattened in sequence without rotating the battery cell fixture 121 by 180°.
