[0042] In the description of this application, examples of some disclosed embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be understood as limiting this application.

[0043] In the description of the present application, many different embodiments or examples are disclosed to implement different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application.

[0044] As the new energy lithium battery industry progresses and develops, requirements for battery cell qualification rates and production efficiency are becoming increasingly stringent. Specifically, a battery may include a battery cell and a current collector plate. The current collector plate may be attached to the end face of the battery cell and electrically connected to the battery cell. The current collector plate may be the positive electrode current collector plate or the negative electrode current collector plate of the battery cell.

[0045] In battery production, an essential step in the battery assembly process involves welding the collector tray to the battery cell and then folding it. During this folding process, the collector tray can become tilted due to the tendency of cylindrical batteries to be placed sideways. Furthermore, the high-speed operation of cylindrical batteries can cause the collector tray to tilt, resulting in a decrease in product yield and a high risk of product failure.

[0046] A battery processing device 100 of the present application can, through multiple operating steps, avoid the problems of deviation of the folding position and deviation of the current collecting tray relative to the battery cell when folding the current collecting tray, thereby simply and effectively improving production efficiency and accuracy, thereby solving at least one of the technical problems existing in the above content.

[0047] Specifically, please refer to Figure 1. In Figure 1, directions A1 and A2 may represent the length directions of the processing equipment 100, directions A3 and A4 may represent the width directions of the processing equipment 100, and directions A5 and A6 may represent the height directions of the processing equipment 100.

[0048] In FIG1 , the processing equipment 100 may include a display device 101. The display device 101 may include a display screen 1011. The display screen 1011 may be located at the top of the processing equipment 100. When a part of the structure of the processing equipment 100 clamps the battery cell to be processed, the display device 101 may display the magnitude of the clamping force on the battery cell, or in other words, the processing equipment 100 may detect the magnitude of the clamping force on the battery cell and display it through the display device 101. By observing the magnitude of the clamping force displayed by the display device 101, it can be determined whether the magnitude of the clamping force on the battery cell is within an appropriate range, thereby preventing the clamping force from being too small to fix the battery cell, causing deflection during the folding step, and preventing the clamping force from being too large to cause deformation and damage to the battery cell.

[0049] In Figure 1, the processing equipment 100 may include a first driving unit 102. The first driving unit 102 may include a first driving member 1021 and a first movable member 1022. The first movable member 1022 is movably connected to the first driving member 1021. The first driving member 1021 can apply a driving force to the first movable member 1022, so that the first movable member 1022 can be driven to move in the direction corresponding to the driving force. The first driving unit 102 may include a slide cylinder. Specifically, the first driving member 1021 may be a cylinder of the slide cylinder, and the first movable member 1022 may be a slide of the slide cylinder.

[0050] In FIG. 1 , the first driving member 1021 may apply a driving force along a direction B1 or a direction B2 .

[0051] In Figure 1 , processing equipment 100 may include a first connecting plate 104. The first connecting plate 104 may be connected to a side of a first movable member 1022. When a driving force is applied by a first driving member 1021, the first connecting plate 104 may be driven by the first movable member 1022 to move in the direction of the driving force. The first connecting plate 104 may be connected to other components of the processing equipment 100, thereby enabling the components to be driven by the first driving member 102 to move at a more suitable position and angle.

[0052] In FIG1 , the processing apparatus 100 may include an end plate 105 . The end plate 105 may have two ends along its length. One end of the end plate 105 may form a pressing end 1051 . The pressing end 1051 may extend relative to the first connecting plate 104 .

[0053] When the end pressure plate 105 is driven by a driving force, the pressing end 1051 can abut against the current collecting plate, and the current collecting plate can be fixed to the end face of the battery cell, thereby limiting the movement space of the battery cell. In this way, when the current collecting plate is folded, the relative position between the battery cell and the current collecting plate can be maintained, avoiding positional deviation between the battery cell and the current collecting plate.

[0054] In FIG1 , the first connecting plate 104 may include a first plate surface 1041 and a second plate surface 1042. The first connecting plate 104 may be connected to the first movable member 1022 via the first plate surface 1041, so that the first movable member 1022 can drive the entire first connecting plate 104 to move. The first connecting plate 104 may be connected to the end pressure plate 105 via the second plate surface 1042, so that the first connecting plate 104 can drive the entire end pressure plate 105 to move. The connection between the first plate surface 1041 and the first connecting plate 104 may include a threaded connection. The connection between the second plate surface 1042 and the end pressure plate 105 may include a threaded connection.

[0055] The plane direction of the first plate surface 1041 can form a corresponding angle with the plane direction of the second plate surface 1042. By adjusting the angle between the first plate surface 1041 and the second plate surface 1042, the posture of the end surface pressure plate 105 on the first connecting plate 104 can be changed accordingly.

[0056] Referring to FIG. 2 , in some cases, the second plate surface 1042 and the end pressure plate 105 may each be provided with a plurality of first connection holes 1052. The plurality of first connection holes 1052 on the second plate surface 1042 may be arranged along the B1 direction and the B2 direction, and may be arranged in a single row or in multiple rows. The plurality of first connection holes 1052 on the end pressure plate 105 may also be arranged along the B1 direction and the B2 direction, and may be arranged in a single row or in multiple rows.

[0057] The end pressure plate 105 can be connected to the first connection holes 1052 of the corresponding part of the second plate surface 1042 through a portion of its own first connection holes 1052. Then, the first connection holes 1052 that are connected between the end pressure plate 105 and the second plate surface 1042 can be connected by penetrating, so that the end pressure plate 105 and the second plate surface 1042 are fixedly connected to each other. The end pressure plate 105 can move relative to the second plate surface 1042 along the B1 direction and the B2 direction, thereby changing the first connection holes 1052 that can be connected between the end pressure plate 105 and the second plate surface 1042, and further adjusting the relative extension distance of the pressing end 1051 on the second plate surface 1042, and ultimately adjusting the pressing effect of the end pressure plate 105 on the battery cell.

[0058] 2 , the end surface pressure plate 105 may include an abutting surface 1053 and an abutting tip 1054. The abutting surface 1053 and the abutting tip 1054 may be located at the abutting end 1051.

[0059] The planar direction of the plane where the abutting surface 1053 is located can be perpendicular to the A1 direction and the A2 direction. When the current collecting plate is placed so that the planar direction of the plate surface is also perpendicular to the A1 direction and the A2 direction, the entire surface of the abutting surface 1053 can be in contact with the current collecting plate, which can increase the area of ​​mutual abutment, so that the current collecting plate can be more stably abutted against the end face of the battery cell.

[0060] The abutting tip 1054 can be located on the side of the pressing end 1051 along the A6 direction, or in other words, can be located on the side of the abutting surface 1053 close to the A6 direction. When the collecting tray is folded, the abutting surface 1053 can abut the portion of the collecting tray close to the A5 direction. The portion of the collecting tray close to the A6 direction will be deformed due to the lack of abutment by the end pressure plate 105 or other structures, and can form a fulcrum for deformation and folding at the location of the abutting tip 1054. In other words, the collecting tray will be in a folded position at the location of the abutting tip 1054.

[0061] On this basis, the folding position of the current collecting tray can be changed accordingly by adjusting the position of the abutting tip 1054 relative to the current collecting tray, which can improve the applicability when the folding position of the current collecting tray needs to be changed.

[0062] In Figure 1, the processing equipment 100 may include a second driving unit 106. The second driving unit 106 may include a second driving member 1061 and a second movable member 1062. The second movable member 1062 is movably connected to the second driving member 1061. The second driving member 1061 can apply a driving force to the second movable member 1062, so that the second movable member 1062 can be driven to move in the direction of the corresponding driving force. The second driving unit 106 may include a slide cylinder. Specifically, the second driving member 1061 may be a cylinder of the slide cylinder, and the second movable member 1062 may be a slide of the slide cylinder.

[0063] In FIG. 1 , the second driving member 1061 may apply a driving force along a B1 direction or a B2 direction.

[0064] In addition, the driving direction of the first driving unit 102 and the driving direction of the second driving unit 106 may be parallel to each other.

[0065] In Figure 1 , the processing apparatus 100 may include a second connecting plate 103. The second connecting plate 103 may be connected to a side of a second movable member 1062. When a driving force is applied by a second driving member 1061, the second connecting plate 103 may be driven by the second movable member 1062 to move in the direction of the driving force. The second connecting plate 103 may be connected to other components of the processing apparatus 100, thereby enabling the components to be driven by the second driving member 106 to move at a more suitable position and angle.

[0066] In FIG1 , the processing device 100 may include a folding adjustment plate 107 . The folding adjustment plate 107 may have two sides along its length. One side of the folding adjustment plate 107 may form a folding end 1071 . The folding end 1071 may extend relative to the second connecting plate 103 .

[0067] When the current collecting plate is pressed by the end surface pressure plate 105 , the folding adjustment plate 107 can be driven by the driving force to approach the current collecting plate on the side of the current collecting plate facing the direction A2 and abut against the current collecting plate.

[0068] Generally, the battery cells can be placed along directions A1 and A2 so that the length direction of the battery cells is parallel to directions A1 and A2. The current collecting plate can be located on the side of the battery cells facing direction A1 and can connect the battery cells.

[0069] The collecting tray can be plate-shaped, with its normal direction parallel to direction A1. The collecting tray can connect to the battery cells via the side facing direction A5. The side of the collecting tray facing direction A6 can extend relative to the battery cells, allowing it to be abutted by the folding adjustment plate 107 and folded with force.

[0070] 3 , the folding adjustment plate 107 may include an extension arm 1073 and a folding piece 1074. The extension arm 1073 and the folding piece 1074 may be located at the folding end 1071. The end of the extension arm 1073 may be connected to the folding piece 1074.

[0071] The folding adjustment plate 107 can abut the collecting disc through the folding member 1074, so that the collecting disc can be deformed and folded by the folding member 1074. The folding member 1074 can be rotatably connected to the extension arm 1073. In the process of the folding member 1074 abutting the collecting disc and folding the collecting disc, the folding member 1074 can change the direction of its force on the collecting disc by rolling, so as to reduce the sliding friction between the folding member 1074 and the collecting disc, so as to avoid the collecting disc from being worn to a large extent; it can also make the force direction of the folding member 1074 on the collecting disc always perpendicular to the plate surface of the collecting disc, thereby ensuring a sufficiently large torque, so as to ensure that the largest possible force is applied to the collecting disc to achieve the folding effect. The folding member 1074 may include a roller.

[0072] The extension arm 1073 can extend in the A5 direction and the A6 direction. When the collecting tray is folded, the plate surface of the collecting tray can be parallel to the A5 direction and the A6 direction, so that the plate surface of the collecting tray can be parallel to the extension arm 1073. Therefore, when the folding adjustment plate 107 is forced to fold the collecting tray by the folding member 1074, the extension arm 1073 connected to the folding member 1074 can structurally avoid the collecting tray, thereby avoiding the situation where the extension arm 1073 structurally limits the collecting tray and makes it unable to fold.

[0073] In Figure 1, the second connecting plate 103 may include a third plate surface 1031 and a fourth plate surface 1032. The second connecting plate 103 may be connected to the second movable member 1062 via the third plate surface 1031, so that the second movable member 1062 can drive the second connecting plate 103 to move as a whole. The second connecting plate 103 may be connected to the folding adjustment plate 107 via the fourth plate surface 1032, so that the second connecting plate 103 can drive the folding adjustment plate 107 to move as a whole. The connection between the third plate surface 1031 and the second connecting plate 103 may include a threaded connection. The connection between the fourth plate surface 1032 and the folding adjustment plate 107 may include a threaded connection.

[0074] The plane direction of the third plate surface 1031 can form a corresponding angle with the plane direction of the fourth plate surface 1032. By adjusting the angle between the third plate surface 1031 and the fourth plate surface 1032, the posture of the folding adjustment plate 107 on the second connecting plate 103 can be changed accordingly.

[0075] Referring to FIG. 3 , in some cases, the fourth plate surface 1032 and the folding adjustment plate 107 may each be provided with a plurality of second connection holes 1072. The plurality of first connection holes 1052 of the fourth plate surface 1032 may be arranged along the B1 direction and the B2 direction, and may be arranged in a single row or in multiple rows. The plurality of first connection holes 1052 of the folding adjustment plate 107 may also be arranged along the B1 direction and the B2 direction, and may be arranged in a single row or in multiple rows.

[0076] The folding adjustment plate 107 can communicate with the first connection holes 1052 of the corresponding portion of the fourth plate surface 1032 through a portion of its own first connection holes 1052. Then, the first connection holes 1052 that communicate with each other between the folding adjustment plate 107 and the fourth plate surface 1032 can be connected by penetrating the connection, so that the folding adjustment plate 107 and the fourth plate surface 1032 are fixedly connected to each other. The folding adjustment plate 107 can move relative to the fourth plate surface 1032 along the B1 direction and the B2 direction, thereby changing the first connection holes 1052 that can communicate with each other between the folding adjustment plate 107 and the fourth plate surface 1032, and further adjusting the relative extension distance of the folding end 1071 on the fourth plate surface 1032. Ultimately, the folding position of the folding adjustment plate 107 on the current collecting plate when folding the current collecting plate can be adjusted.

[0077] Based on the above content, in some cases, the A1 direction and the A2 direction can be horizontal directions, the A5 direction and the A6 direction can be vertical directions, and the current collecting tray can be placed vertically. When folding the current collecting tray, the upper half of the current collecting tray can be abutted against the end face of the battery cell to limit the relative position between the current collecting tray and the battery cell. When the current collecting tray and the battery cell are welded together, the current collecting tray can be prevented from being subjected to force, which may cause the welding point between the current collecting tray and the battery cell to detach or disconnect. The lower half of the current collecting tray will be abutted and folded, and eventually a larger angle (such as 90 degrees) can be formed between the upper and lower halves of the current collecting tray, thereby achieving the expected effect of folding the current collecting tray.

[0078] In Figure 1 , the processing equipment 100 may include an adjustment base 1081. The adjustment base 1081 may be connected to the corresponding structure of the processing equipment 100 and may drive the corresponding structure of the processing equipment 100 to move along the A5 direction and the A6 direction, thereby achieving the effect of adjusting the position of the corresponding structure of the processing equipment 100.

[0079] Specifically, the first drive unit 102 can be connected to an adjustment seat 1081, so that the first drive unit 102 can be driven by the adjustment seat 1081 to adjust its position in the vertical direction to change the folded position of the current collecting tray. The second drive unit 106 can be connected to an adjustment seat 1081, so that the second drive unit 106 can be driven by the adjustment seat 1081 to adjust its position in the vertical direction to change the position of the force applied to the current collecting tray.

[0080] In FIG1 , the processing equipment 100 may include a vertical plate 1082 . The vertical plate 1082 may be placed along the A5 direction and the A6 direction. The first drive unit 102 and the second drive unit 106 may be connected to the vertical plate 1082 , so that the vertical plate 1082 can play a corresponding supporting role.

[0081] In FIG1 , the processing equipment 100 may include a reinforcing rib plate 1083 . The reinforcing rib plate 1083 may be placed along the A5 direction and the A6 direction. The vertical plate 1082 may be connected to the reinforcing rib plate 1083 , so that the reinforcing rib plate 1083 can play a corresponding role in stabilizing the installation.

[0082] In FIG. 1 , the two vertical plates 1082 may be arranged along the A5 direction and the A6 direction, and the first driving unit 102 and the second driving unit 106 are respectively fixedly connected to a corresponding vertical plate 1082 .

[0083] Specifically, in FIG1 , the first driving portion 102 can be fixedly connected to a corresponding vertical plate 1082 via a first driving member 1021. The first driving portion 102 can be located at a position tilted upward relative to the first clamping arm 129. The first driving member 1021 can drive the first movable member 1022 to move tilted upward along a B1 direction to move the pressing end 1051 away from the first clamping arm 129, and can drive the first movable member 1022 to move tilted downward along a B2 direction to move the pressing end 1051 closer to the first clamping arm 129.

[0084] The second driving portion 106 can be fixedly connected to a corresponding vertical plate 1082 via a second driving member 1061, and can be located below the first driving portion 102. The second driving portion 106 can be substantially on the same horizontal plane as the first clamping arm 129. The second driving member 1061 can drive the second movable member 1062 to move obliquely upward along the B1 direction so that the folding end 1071 can be located on the side of the first clamping arm 129 facing the second driving member 1061, and can drive the second movable member 1062 to move obliquely downward along the B2 direction so that the folding end 1071 can be located on the side of the first clamping arm 129 facing away from the second driving member 1061.

[0085] On the basis of the above, by adjusting the connection position of the vertical plate 1082 on the reinforcing rib plate 1083, the installation position of the first driving part 102 or the second driving part 106 can be adjusted accordingly.

[0086] Based on the above, the processing equipment 100 may include a current collecting tray folding mechanism. The current collecting tray folding mechanism may include a first drive unit 102 and a second drive unit 106. Through the coordination between the first drive unit 102 and the second drive unit 106, the processing equipment 100 can ensure that the folding position of the current collecting tray meets the desired folding effect, thereby preventing deviation of the folding line and affecting the yield rate.

[0087] In Figures 1, 4, and 5, the processing equipment 100 may include first clamping arms 129. Two first clamping arms 129 may be located on the processing equipment 100 near the first drive unit 102 and the second drive unit 106. The two first clamping arms 129 may move toward each other along directions A3 and A4, respectively, so that the current collecting tray located between the two first clamping arms 129 can be clamped and fixed by the two first clamping arms 129. The first clamping arms 129 may include clamping claws.

[0088] In FIG5 , the first clamping arm 129 may include an upper protrusion 1291 and a lower protrusion 1292. The upper protrusion 1291 may be located on the side of the first clamping arm 129 close to the A5 direction. The lower protrusion 1292 may be located on the first clamping arm 129 and below the upper protrusion 1291. When the two first clamping arms 129 approach each other, the first clamping arm 129 may abut against the current collecting plate via the upper protrusion 1291 and the lower protrusion 1292, respectively. Due to the provision of the upper protrusion 1291 and the lower protrusion 1292, the contact area between the first clamping arm 129 and the current collecting plate can be reduced, thereby making the force transmitted between the first clamping arm 129 and the current collecting plate more concentrated, and the current collecting plate can be more firmly fixed between the two first clamping arms 129, which helps to improve the effect of the first clamping arm 129 in clamping and fixing the current collecting plate.

[0089] In Figures 1, 4, and 5, the processing equipment 100 may include a third drive unit 131. The third drive unit 131 can drive the two first clamping arms 129 to move toward or away from each other. The third drive unit 131 can be located on the side of the two first clamping arms 129 that is closer to the A6 direction, or in other words, can be located at the bottom of the two first clamping arms 129. The third drive unit 131 is located away from the side of the two first clamping arms 129 that is closer to the A5 direction, allowing the third drive unit 131 to avoid the collecting plate. The third drive unit 131 can include a thin pneumatic finger.

[0090] In addition, the third driving portion 131 may also only drive one of the two first clamping arms 129 to move closer to or away from the other one, so as to achieve a corresponding clamping effect.

[0091] In Figures 1, 4, and 5, the processing apparatus 100 may include second clamping arms 123. The two second clamping arms 123 may be located on the processing apparatus 100, away from the first drive unit 102 and the second drive unit 106. The two second clamping arms 123 may move toward each other along directions A3 and A4, respectively, so that the battery cell located between the two second clamping arms 123 can be clamped and secured by the two second clamping arms 123. The second clamping arms 123 may include clamping claws.

[0092] In Figure 5 , the second clamping arms 123 may include supporting arms 1231. Each second clamping arm 123 may include one supporting arm 1231 along the A1 direction and another supporting arm 1231 along the A2 direction. When clamping a battery cell, the supporting arms 1231 on the two second clamping arms 123 near the A1 direction cooperatively clamp the side of the battery cell facing the A1 direction, and the supporting arms 1231 on the two second clamping arms 123 near the A2 direction cooperatively clamp the side of the battery cell facing the A2 direction, thereby clamping both ends of the battery cell.

[0093] In FIG5 , the second clamping arm 123 may be formed with a recess 1232 on the support arm 1231. The surface of the support arm 1231 forming the recess 1232 may include a plurality of contact planes 1233. The plurality of contact planes 1233 may be sequentially connected and sequentially form angles, so that the surface forming the recess 1232 may have a broken line structure. When clamping a battery cell, the battery cell will be accommodated in the recess 1232 and may abut against the corresponding contact planes 1233 in the recess 1232 through surfaces at different positions. The provision of the plurality of contact planes 1233 may reduce the contact area between the support arm 1231 and the battery cell, thereby making the force transmitted between the support arm 1231 and the battery cell more concentrated, and making the battery cell more firmly fixed between the two second clamping arms 123, which is conducive to improving the effect of the second clamping arm 123 on the clamping and fixing of the battery cell.

[0094] Moreover, the support arms 1231 can clamp the battery cells through the contact planes 1233 in different directions, so that the battery cells can be limited and fixed from different directions, which is beneficial to improving the fixing effect of the battery cells.

[0095] In Figures 1 and 5, the processing equipment 100 may include a fourth drive unit 134. The fourth drive unit 134 can drive the two second clamping arms 123 to move toward or away from each other. The fourth drive unit 134 can be located on the side of the two second clamping arms 123 that is closer to the A6 direction, or in other words, can be located at the bottom of the two second clamping arms 123. The fourth drive unit 134 is located away from the side of the two second clamping arms 123 that is closer to the A5 direction, allowing the fourth drive unit 134 to avoid the battery cells. The fourth drive unit 134 can include a thin pneumatic finger.

[0096] In addition, the fourth driving portion 134 may also only drive one of the two second clamping arms 123 to move closer to or away from the other one, so as to achieve a corresponding clamping effect.

[0097] In Figures 1, 4, and 5, the processing equipment 100 may include a guide member 132. The guide member 132 may be disposed on a side of one of the second clamping arms 123, away from the other second clamping arm 123. When the second clamping arm 123 is driven to move, the guide member 132 guides the second clamping arm 123, allowing the second clamping arm 123 to move in a desired direction, thereby enabling the second clamping arm 123 to move smoothly. The guide member 132 may include a linear bearing.

[0098] In Figures 1, 4, and 5, the processing equipment 100 may include a buffer member 133. The buffer member 133 may be disposed on a side of one of the second clamping arms 123, away from the other second clamping arm 123. When the second clamping arm 123 is driven to move, the buffer member 133 provides a cushion when the second clamping arm 123 contacts the battery cell, preventing the second clamping arm 123 from squeezing and deforming the battery cell due to excessive driving force. The buffer member 133 may include a spring plunger.

[0099] In Figures 1, 4, and 5, the processing equipment 100 may include a pressure sensor 122. The pressure sensor 122 may be disposed on a side of one of the second clamping arms 123, away from the other second clamping arm 123. When the second clamping arm 123 is driven to move, the pressure sensor 122 may detect the force with which the second clamping arm 123 clamps the battery cell and may provide feedback of the detected force to the display device 101.

[0100] In Figures 1, 4, and 5, the processing equipment 100 may include a regulating valve 125. In the case where the corresponding structure of the processing equipment 100 is driven by air pressure, the regulating valve 125 can be used to adjust the air pressure value of the corresponding structure to adapt to different actual conditions.

[0101] In Figures 1, 4, and 5, the regulating valve 125 may include a first valve 1251 and a second valve 1252. The first valve 1251 can regulate the air pressure of all driving mechanisms in the processing equipment 100 that achieve a driving effect through air pressure (such as the first driving unit 102, the second driving unit 106, the third driving unit 131, and the fourth driving unit 134), thereby achieving an overall air pressure regulation effect. The second valve 1252 can regulate the air pressure of driving mechanisms in the processing equipment 100 that achieve a driving effect through air pressure and require precise control (such as the fourth driving unit 134), thereby achieving a fine adjustment effect on the driving force.

[0102] Among them, the fourth driving part 134 is mainly used to drive the second clamping arm 123, and the second valve 1252 can finely adjust the driving force of the fourth driving part 134, so as to finely adjust the clamping force of the second clamping arm 123 on the battery cell, thereby avoiding the situation where the clamping force is too large and the battery cell is damaged, and the clamping force is too small and the battery cell cannot be fixed.

[0103] In Figures 1, 4, and 5, the processing equipment 100 may include a first support portion 127. The first support portion 127 may include a support plate 1271 and a support column 1272. The second clamping arm 123 and the fourth drive unit 134 may be located on the side of the support plate 1271 facing the A5 direction and disposed on the support plate 1271, so that the support plate 1271 can support the second clamping arm 123 and the fourth drive unit 134. The support column 1272 may be located on the side of the support plate 1271 facing the A6 direction and may be connected to the support plate 1271. The support column 1272 may extend along the A5 and A6 directions to form its own length. The support plate 1271 may be connected to multiple support columns 1272. The multiple support columns 1272 may have the same length. The support columns 1272 may be configured with different lengths to adapt to the height of the battery cells according to the height of the folding position of the current collecting tray.

[0104] In FIG. 1 , FIG. 4 , and FIG. 5 , the processing equipment 100 may include a second supporting portion 110 .

[0105] The second supporting portion 110 may include a bottom plate 111. The bottom plate 111 may be located on one side of the processing equipment 100 along the A6 direction. The bottom plate 111 may be located at the bottom of the processing equipment 100, thereby supporting the structures of other parts of the processing equipment 100.

[0106] The second support portion 110 may include a bottom pad 112. The bottom pad 112 may be provided on a side of the bottom plate 111 facing the A6 direction, and may provide a certain buffering effect while the bottom plate 111 supports the bottom plate 111, so that the processing equipment 100 can be placed more stably.

[0107] The processing equipment 100 may include a handle 113. The handle 113 may be fixedly connected to the base plate 111. The handle 113 may provide a fulcrum to facilitate the operator to carry the processing equipment 100.

[0108] In Figure 1 , processing equipment 100 may include a control valve 114. Control valve 114 may be mounted on base plate 111. Processing equipment 100 may be equipped with multiple control valves 114. Each of the first drive unit 102, second drive unit 106, third drive unit 131, and fourth drive unit 134 may correspond to a corresponding control valve 114. By operating the control valves 114, the corresponding first drive unit 102, second drive unit 106, third drive unit 131, and fourth drive unit 134 can be controlled to generate a driving force.

[0109] In some cases, this application can be applied to the following application scenarios:

[0110] Place the battery cell between the two second clamping arms 123; clamp the current collecting plate by controlling the first clamping arm 129; clamp the battery cell by controlling the second clamping arm 123; generate a driving force by controlling the first driving part 102 so that the current collecting plate is abutted against the end face of the battery cell by the first movable part 1022; release the clamping of the current collecting plate by controlling the first clamping arm 129; generate a driving force by controlling the second driving part 106 so that the current collecting plate is abutted against the second movable part 1062 and deformed and folded.

[0111] In the above application scenario, the collecting plate can be fixed quickly and accurately, the collecting plate can be folded stably, the folding position can be precisely controlled, the folding steps are simple and easy to implement, and a one-folding effect can be achieved. The structure of the processing equipment 100 itself is simple and reliable, which can ultimately ensure the high quality and high efficiency of the collecting plate in the folding process.

[0112] Based on the above content, the technical concept of this application can be reflected through the following content, and the specific implementation principles of some of the contents can refer to the above content. In order to avoid redundancy, they will not be elaborated here.

[0113] The present application provides a battery processing device 100, wherein the battery may include a battery cell and a current collecting tray. The processing device 100 may include a battery cell clamping mechanism, a current collecting tray clamping mechanism, and a current collecting tray folding mechanism.

[0114] The cell clamping mechanism can be used to position the cell. The cell clamping mechanism can have a loose state and a clamped state. When the cell clamping mechanism is in the loose state, the cell can move relative to the cell clamping mechanism. When the cell clamping mechanism is in the clamped state, the cell can be fixed and immovable relative to the cell clamping mechanism. The collector tray clamping mechanism can be used to clamp and correct the angle of the collector tray when the cell clamping mechanism is in the loose state. The collector tray folding mechanism can be used to fold the collector tray when the cell clamping mechanism is in the clamped state.

[0115] The above-mentioned processing equipment 100, by first fixing the current collecting plate and then fixing the battery cell, can maintain the relative position between the current collecting plate and the battery cell when clamping the battery cell. When folding the current collecting plate, it can avoid the deviation of the folding position on the current collecting plate due to the angular offset of the current collecting plate relative to the battery cell, which is beneficial to ensuring the yield rate of the battery.

[0116] Specifically, when the battery cell is placed on the battery cell clamping mechanism, the current collecting tray may have an angular offset relative to the battery cell, or may not be in the preset posture, which will cause the fold line generated by the current collecting tray folding mechanism to be offset. By clamping and correcting the angle of the current collecting tray by the current collecting tray clamping mechanism, the current collecting tray can be clamped by the current collecting tray clamping mechanism and returned to the preset posture. When the current collecting tray is in the preset posture, the fold line generated by the current collecting tray folding mechanism when folding the current collecting tray will also be in the expected position without offset. In Figure 1, the current collecting tray clamping mechanism can move along the A3 direction and the A4 direction to clamp the current collecting tray, and the current collecting tray folding mechanism can move along the B1 direction and the B2 direction to fold the current collecting tray.

[0117] In particular, please refer to Figure 6. The structure shown in the battery 200 can be used to understand the battery described in other contents of this application. In Figure 6, the battery 200 may include a battery cell 201 and a current collecting tray 202. The battery cell 201 may form two ends along the C1 direction and the C2 direction respectively. The current collecting tray 202 may be connected to the end face of the battery cell 201 along the C1 direction. The current collecting tray 202 may extend along the C3 direction and the C4 direction. The side of the current collecting tray 202 close to the C4 direction is connected to the battery cell 201, and the side of the current collecting tray 202 close to the C3 direction will extend relative to the battery cell 201. For the processing equipment 100, the side of the current collecting tray 202 close to the C3 direction will be folded, so that the side of the current collecting tray 202 close to the C3 direction is bent toward the C1 direction to achieve the folding effect of the current collecting tray 202, thereby facilitating the subsequent processing of the battery 200.

[0118] 7 , 8 and 9 , FIG. 7 may illustrate the situation before the collecting tray 202 is folded, FIG. 8 may illustrate the situation when the collecting tray 202 is folded, and FIG. 9 may illustrate the situation after the collecting tray 202 is folded.

[0119] In some cases, the A1 and A2 directions may be the axial directions of the central axis of the battery cell 201 clamped by the battery cell clamping mechanism, or the axial directions of the central axis of the current collecting tray 202 clamped by the current collecting tray clamping mechanism. The central axis of the battery cell 201 may be the central axis corresponding to the geometric structure of the battery cell 201 itself (for example, if the geometric structure of the battery cell 201 is cylindrical, the central axis of the battery cell 201 may be the central axis of the cylinder). The central axis of the portion of the current collecting tray 202 extending from the battery cell 201 may be the central axis corresponding to the geometric structure of the portion of the current collecting tray 202 extending from the battery cell 201 itself (for example, if the geometric structure of the portion of the current collecting tray 202 extending from the battery cell 201 is disc-shaped, the central axis of the portion of the current collecting tray 202 extending from the battery cell 201 may be the central axis of the disc). The A5 and A6 directions may be directions perpendicular to the surface of the bottom plate 111. When the bottom plate 111 is placed horizontally, the A5 and A6 directions may be vertical directions.

[0120] In FIG7 , the battery cell clamping mechanism can clamp the battery cell 201. The end face pressure plate 105 can be driven to move obliquely downward along the B2 direction, so that the pressing end 1051 can approach and abut the current collecting disc 202 from the oblique upward direction of the current collecting disc 202, and can cause the current collecting disc 202 to abut against the end face of the battery cell 201 facing the A1 direction (or, in other words, toward the first driving member 1021). The folding member 1074 is located on the side of the first clamping arm 129 facing away from the second driving member 1061. The folding member 1074 can be driven to move obliquely upward along the B1 direction (or, in other words, along the first clamping arm 129 toward the second driving member 1061). During this movement, the folding member 1074 abuts the portion of the current collecting disc 202 extending from the battery cell 201, and then applies force to the portion of the current collecting disc 202 extending from the battery cell 201, causing the portion of the current collecting disc 202 extending from the battery cell 201 to be folded, thereby forming the situation shown in FIG8 .

[0121] In FIG7 , the portion of the collecting tray 202 extending from the battery cell 201 extends in the direction A6 (or downward). In FIG8 , the portion of the collecting tray 202 extending from the battery cell 201 extends in the direction A1 due to being folded. After the portion of the collecting tray 202 extending from the battery cell 201 is folded, the folding member 1074 can be driven to move obliquely downward in the direction B2, and the end pressure plate 105 can be driven to move obliquely upward in the direction B1, so that the collecting tray folding mechanism can be restored to its pre-actuated state, resulting in the situation shown in FIG9 .

[0122] 1 , the collecting plate clamping mechanism may include a set of first clamping arms 129. The set of first clamping arms 129 can move closer to each other along a first direction to clamp the collecting plate, and can move away from each other along the first direction to release the collecting plate.

[0123] In this way, the current collecting plate can be clamped and released.

[0124] 1 , the first direction may correspond to the A3 direction and the A4 direction. The first first clamping arm 129 may move along the A3 direction to approach the second first clamping arm 129 , and the second first clamping arm 129 may move along the A4 direction to approach the first first clamping arm 129 .

[0125] Referring to Figure 5 , the first clamping arm 129 may have a clamping surface 1290 that faces the current collecting tray when clamping the current collecting tray. Each first clamping arm may have at least two protrusions arranged along the second direction on the clamping surface 1290. The protrusions on each first clamping arm protrude from the clamping surface 1290 along the first direction by an equal amount.

[0126] In FIG5 , the raised portion may include an upper protrusion 1291 and a lower protrusion 1292 . The first direction may correspond to the A3 direction and the A4 direction. The second direction may correspond to the A5 direction and the A6 direction. The upper protrusion 1291 and the lower protrusion 1292 may be arranged to protrude from the clamping surface 1290 and be spaced relative to each other. The upper protrusion 1291 and the lower protrusion 1292 may have equal protrusion dimensions along the first direction, so that the first clamping arm 129 can clamp the collecting plate together with the upper protrusion 1291 and the lower protrusion 1292, ensuring sufficient contact area between the first clamping arm 129 and the collecting plate, thereby improving the clamping strength of the collecting plate.

[0127] This is beneficial to improving the clamping and fixing effect of the collecting plate.

[0128] 5 , the cell clamping mechanism may include a second clamping arm 123. The second clamping arm 123 may be located on a side of the current collecting tray clamping mechanism away from the current collecting tray folding mechanism. The cell clamping mechanism may have at least two second clamping arms 123 close to each other to clamp the cell.

[0129] In this way, the battery cell can be clamped.

[0130] Referring to Figure 5 , the second clamping arm 123 may be formed with a recess 1232. The surface of the second clamping arm 123 forming the recess 1232 may include multiple contact planes 1233. The multiple contact planes 1233 may be sequentially connected and sequentially form angles. The second clamping arm 123 may clamp the battery cell using at least a portion of the multiple contact planes 1233.

[0131] This is beneficial to improving the fixation effect of the battery cell.

[0132] 5 , the battery cell clamping mechanism may include a guide member 132 . The guide member 132 may be used to guide the movement direction of the at least one second clamping arm 123 .

[0133] In this way, the stability of the second clamping arm 123 during movement can be improved.

[0134] 5 , the battery cell clamping mechanism may include a buffer 133. The buffer 133 may be used to provide a buffering force when the second clamping arm 123 clamps the battery cell.

[0135] This can prevent the battery cells from being damaged.

[0136] Referring to FIG1 , the processing device 100 may include a pressure sensor 122 and a display screen 1011. The pressure sensor 122 may be used to detect the pressure value when the second clamping arm 123 clamps the battery cell. The display screen 1011 may be electrically connected to the pressure sensor 122. The display screen 1011 may be used to display the pressure value.

[0137] In this way, the clamping status of the battery cell can be fed back in time.

[0138] 1 , the processing equipment 100 may include a regulating valve 125. The regulating valve 125 can adjust the clamping force of the second clamping arm 123 on the battery cell.

[0139] In this way, the clamping force of the battery cell can be adjusted according to the specific situation, which can avoid the clamping force being too small to fix the battery cell and causing deflection during the folding step, and can avoid the clamping force being too large to cause deformation and damage to the battery cell.

[0140] 1 and 4 , the regulating valve 125 may include a first valve 1251 and a second valve 1252. The first valve 1251 may coarsely adjust the clamping force of the second clamping arm 123, or in other words, the first valve 1251 may adjust the clamping force of the second clamping arm 123 with a larger adjustment range. The second valve 1252 may finely adjust the clamping force of the second clamping arm 123, or in other words, the second valve 1252 may adjust the clamping force of the second clamping arm 123 with a smaller adjustment range.

[0141] Referring to Figure 1 , the current collecting tray folding mechanism may include a supporting portion and a folding portion. At least a portion of the supporting portion can be driven to abut the current collecting tray against the battery cell. The folding portion and the supporting portion can be spaced apart. At least a portion of the supporting portion can be driven to apply force to at least a portion of the current collecting tray, causing the at least portion of the current collecting tray to fold under the force.

[0142] This helps to prevent the collecting plate from being displaced when it is folded.

[0143] In some cases, the abutting portion may include a first driving portion 102, a first connecting plate 104, and an end pressure plate 105. The abutting portion may generate a driving force through the first driving portion 102, so that the first connecting plate 104 moves and drives the end pressure plate 105 to move, and the end pressure plate 105 is driven to abut against the current collecting plate, thereby causing the current collecting plate to abut against the battery cell.

[0144] In some cases, the folding portion may include a second driving portion 106, a second connecting plate 103, and a folding adjustment plate 107. The folding portion may generate a driving force through the second driving portion 106, so that the second connecting plate 103 moves and drives the folding adjustment plate 107 to move, and the folding adjustment plate 107 can be driven to abut against the current collecting plate, thereby applying force to fold a portion of the structure of the current collecting plate.

[0145] 2 , the abutting portion may include an abutting surface 1053 and an abutting tip 1054. The abutting portion may abut the current collecting tray via the abutting surface 1053. The abutting tip 1054 is located at one end of the abutting surface 1053 and may cooperate with the folding portion to fold the current collecting tray, such that the folded position of the current collecting tray is located at the position where the abutting tip 1054 abuts the current collecting tray.

[0146] In this way, it is beneficial to realize folding at the expected folding position on the current collecting tray, and the folding position of the current collecting tray can be controlled.

[0147] 3 , the folding portion may include a folding member 1074 . The folding member 1074 may be rotatably located on the folding portion. The folding portion may apply force to the collecting plate via the folding member 1074 .

[0148] This helps to reduce the sliding friction generated when the collecting plate is folded, thereby preventing the collecting plate from being subjected to a greater degree of wear.
