DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] The embodiment of the present application provides a cell end face shaping device and method, the cell end face shaping device sequentially conveys the cell to multiple shaping modules, and the multiple shaping modules sequentially press and shape the end face of the cell, and each shaping of the cell end face is to further press the pole ear at the end of the cell on the basis of the previous shaping step, and the pole ear at the end of the cell gradually adheres to the end of the cell under multiple pressing, thus completing the cell end face shaping process. The present application can solve the technical problem in the related art that metal powder is easily generated when shaping the cell end face, which affects the quality of the cell.

[0043] Reference Figure 1 and Figure 2 , a cell end face shaping device comprises a conveying mechanism 1 and a plurality of shaping modules 2. The conveying mechanism 1 is used to drive the cell to pass through the plurality of shaping modules 2 in sequence, and the shaping modules 2 are used to press and shape the cell end face.

[0044] Reference Figure 1 and Figure 2, wherein the conveying mechanism 1 includes a conveying platform 101, a conveying assembly (not shown in the figure) and a plurality of jigs 102. The conveying assembly is mounted on the conveying platform 101 and its conveying direction is consistent with the length direction of the conveying platform 101. A plurality of jigs 102 are evenly spaced and connected to the driving end of the conveying assembly so as to pass through a plurality of shaping modules 2 in sequence under the drive of the conveying assembly. Specifically, the conveying assembly includes a belt conveying assembly, and the jig 102 is fixed to the belt of the belt conveying assembly by bolts. The jig 102 is used to carry the battery cell. Specifically, after the battery cell is placed on the jig 102, the length direction of the battery cell is consistent with the width direction of the conveying platform 101.

[0045] Reference Figure 1-Figure 3 The shaping module 2 includes a shaping seat 203 and a shaping assembly 201. The shaping seat 203 is fixed on the conveying platform 101 by bolts, and a plurality of shaping seats 203 are arranged at intervals along the length direction of the conveying platform 101. The shaping assembly 201 is installed on the shaping seat 203, which includes a shaping surface 201a, which is used to press the pole ear at the end of the battery cell so that the pole ear is attached to the shaping surface 201a, and at the same time, the pole ear is moved close to the end face of the battery cell to shape the end face of the battery cell.

[0046] Reference Figure 1-Figure 3 Furthermore, along the conveying direction of the conveying mechanism 1, the angle between the shaping surfaces 201a of the multiple shaping components 201 and the end face of the cross section of the battery cell gradually decreases. Therefore, as the multiple shaping components 201 press the pole ears at the ends of the battery cells, the pole ears at the ends of the battery cells can gradually adhere to the end faces of the battery cells.

[0047] Reference Figure 3-Figure 5 Specifically, the shaping assembly 201 includes two shaping pieces 2011 and two shaping linear modules 2012. The two shaping pieces 2011 are arranged opposite to each other in the width direction of the conveyor 101, and are both slidably arranged on the shaping seat 203. The battery cell is transferred between the two shaping pieces 2011 as the jig 102 moves, that is, the two shaping pieces 2011 are respectively opposite to the two end faces of the battery cell. The shaping piece 2011 is disc-shaped, and the sides of the two shaping pieces 2011 facing each other are provided with a shaping cavity 2011a, and the side wall of the shaping cavity 2011a is the shaping surface 201a. The two shaping pieces 2011 move towards each other and are respectively pressed against the two ends of the battery cell. The pole ears at the ends of the battery cell are accommodated in the shaping cavity 2011a, and the pole ears are in contact with the shaping surface 201a.

[0048] Reference Figure 3-Figure 5, the two shaping linear modules 2012 are also spaced apart in the width direction of the conveyor platform 101, the fixed ends of the two shaping linear modules 2012 are fixed to the shaping seat 203 by bolts, the driving ends of the two shaping linear modules 2012 move towards or away from each other in the width direction of the conveyor platform 101, and the driving ends of the two shaping linear modules 2012 are respectively fixed to the shaping member 2011, and the driving ends of the shaping linear modules 2012 and the shaping member 2011 can be fixed by bolts, welding or plugging. Therefore, under the action of the shaping linear module 2012, the two shaping members 2011 can move towards each other to shape the end face of the battery cell. Specifically, the shaping linear module 2012 includes a cylinder, and in other embodiments, the shaping linear module 2012 may also include a screw mechanism or a linear motor.

[0049] In some embodiments, the shaping assembly 201 further includes two shaping rotating drive members, the fixed end of the shaping rotating drive member is fixed to the driving end of the shaping linear module 2012, and the driving end of the shaping rotating drive member is fixed to the shaping member 2011. When the two shaping members 2011 clamp the battery cell, the rotation axis of the shaping member 2011 is consistent with the axis of the battery cell. Due to the setting of the shaping rotating drive member, when the shaping surface 201a presses against the pole ear, the shaping surface 201a rotates at the same time, which has a smoothing effect on the pole ear, so that the pole ear is tightly pressed, thereby improving the quality of the end face shaping of the battery cell.

[0050] Reference Figure 4 and Figure 5 Optionally, the shaping module 2 also includes a shaping and pressing component 202, which is used to press the battery cell onto the jig 102, and restrict the movement of the battery cell when the shaping component 201 acts on the battery cell. The shaping and pressing component 202 includes a shaping and pressing member 2021 and a shaping and pressing linear module 2022. The shaping and pressing member 2021 is lifted and slidably arranged on the shaping seat 203. The shaping and pressing member 2021 is arranged in a block shape, and its bottom surface shape matches the shape of the circumferential side surface of the battery cell. The shaping and pressing member 2021 slides down and firmly presses the battery cell onto the jig 102.

[0051] Reference Figure 4 and Figure 5 The fixed end of the shaping and pressing linear module 2022 is fixed to the shaping seat 203 by bolts, and the driving end of the shaping and pressing linear module 2022 moves up and down and is fixed to the shaping and pressing member 2021, so that the shaping and pressing linear module 2022 drives the shaping and pressing member 2021 to press on the battery cell, and restricts the movement of the battery cell during the shaping process, so as to ensure the smooth shaping of the battery cell end surface. Specifically, the shaping and pressing linear module 2022 includes a cylinder, and in other embodiments, the shaping and pressing linear module 2022 may also include a screw mechanism or a linear motor.

[0052] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 Specifically, the plurality of shaping modules 2 include a first shaping module 2a and a plurality of second shaping modules 2b, and the first shaping module 2a and the second shaping module 2b are arranged in sequence in the conveying direction of the conveying mechanism 1, that is, the battery cell is first processed by the first shaping module 2a and then by the second shaping module 2b. In this embodiment, the number of the second shaping modules 2b is 2.

[0053] Reference Figure 3 and Figure 4 Specifically, the shaping surface 201a of the shaping component 201 in the first shaping module 2a is arranged perpendicular to the cross-section of the battery cell. When the battery cell is shaped at the first shaping module 2a, the pole ears at the end faces of the battery cell are gathered into the shaping cavity 2011a, and the pole ears at the ends of the battery cell only contact the edges of the shaping surface 201a. Under the gathering effect of the first shaping module 2a on the pole ears, when the pole ears are subsequently pressed, the pole ears are neater and easier to adhere to the end faces of the battery cell.

[0054] Reference Figure 3 and Figure 5 Specifically, the plurality of second shaping modules 2b are also arranged at intervals along the conveying direction of the conveying mechanism 1, and the angle between the shaping surface 201a of the shaping component 201 in the second shaping module 2b and the cross section of the battery cell gradually decreases along the conveying direction of the conveying mechanism 1. It can be understood that the plurality of second shaping modules 2b gradually make the tabs at the ends of the battery cell fit the end faces of the battery cell.

[0055] Reference Figure 3 and Figure 5 The shaping surface 201a of the shaping component 201 in the second shaping module 2b is set at an acute angle to the cross section of the battery cell. Optionally, the shaping surface 201a can be a plane or a curved surface.

[0056] Reference Figure 1 , Figure 2 and Figure 6 Optionally, the battery cell end face shaping device also includes a shaping module 3. The shaping module 2 and the shaping module 3 are arranged sequentially in the conveying direction of the conveying mechanism 1. It can be understood that after the battery cell is end-face shaped by the shaping module 2, it is processed by the shaping module 3.

[0057] Reference Figure 1 , Figure 3 and Figure 6The shaping module 3 includes a shaping seat 303 and a shaping assembly 301. The shaping seat 303 is fixed on the conveying platform 101 by bolts, and the shaping assembly 301 is installed on the shaping seat 303. The shaping assembly 301 includes a shaping plane 301a, which is used to press the pole ear at the end of the battery cell so that the pole ear is attached to the end face of the battery cell, thereby completing the process of shaping the end face of the battery cell.

[0058] Reference Figure 1 , Figure 3 and Figure 6 Specifically, the shaping assembly 301 includes two shaping pieces 3011 and two shaping linear modules 3012. The two shaping pieces 3011 are arranged opposite to each other in the width direction of the conveying platform 101. The conveying assembly can transport the battery cell to between the two shaping pieces 3011. The two shaping pieces 3011 are slidably arranged on the shaping seat 303 to move closer to or farther from each other. The shaping pieces 3011 are arranged in a plate shape, and the sides of the two shaping pieces 3011 facing each other are shaping planes 301a. When the two shaping pieces 3011 move closer to each other, the two shaping planes 301a respectively press against the tabs at both ends of the battery cell, so that the tabs are attached to the end faces of the battery cell, thereby completing the shaping of the end faces of the battery cell.

[0059] Reference Figure 1 , Figure 3 and Figure 6 , two shaping linear modules 3012 are spaced apart in the width direction of the conveyor platform 101, and the fixed end of the shaping linear module 3012 is fixed to the shaping seat 303 by bolts. The driving ends of the two shaping linear modules 3012 move toward or away from each other and are respectively fixed to the two shaping members 3011, and the driving ends of the shaping linear modules 3012 and the shaping members 3011 can be fixed by bolts, welding or plugging. The shaping member 3011 is driven to move by the shaping linear module 3012, so that the shaping plane 301a presses against the pole ear, thereby completing the end face shaping of the battery cell. Specifically, the shaping linear module 3012 includes a cylinder, and in other embodiments, the shaping linear module 3012 may also include a screw mechanism or a linear motor.

[0060] In this way, due to the setting of the shaping module 3, on the one hand, the pole ear can be completely attached to the end face of the battery cell, improving the end face shaping effect of the battery cell; on the other hand, the state of the pole ear attached to the end face of the battery cell is shaped to avoid the occurrence of the pole ear rebound.

[0061] In some embodiments, the shaping component 301 further includes two shaping rotating drive members, the fixed end of the shaping rotating drive member is fixed to the driving end of the shaping linear module 3012, and the driving end of the shaping rotating drive member is fixed to the shaping member 3011. When the two shaping members 3011 clamp the battery cell, the rotation axis of the shaping member 3011 is consistent with the axis of the battery cell. Due to the setting of the shaping rotating drive member, when the shaping plane 301a presses against the pole ear, the shaping plane 301a rotates at the same time, which has a smoothing effect on the pole ear, so that the pole ear is tightly pressed, thereby improving the quality of the end face shaping of the battery cell.

[0062] Reference Figure 1 and Figure 6 Optionally, the shaping module 3 further includes a shaping and pressing component 302, which is used to press the battery cell onto the jig 102, and restrict the movement of the battery cell when the shaping component 301 acts on the battery cell. The shaping and pressing component 302 includes a shaping and pressing member 3021 and a shaping and pressing linear module 3022. The shaping and pressing member 3021 is lifted and slidably arranged on the shaping seat 303, and the shaping and pressing member 3021 is arranged in a block shape, and the shape of its bottom surface matches the shape of the circumferential side surface of the battery cell, and the shaping and pressing member 3021 slides down and firmly presses the battery cell onto the jig 102.

[0063] Reference Figure 1 and Figure 6 The fixed end of the shaping and clamping linear module 3022 is fixed to the shaping seat 303 by bolts, and the driving end of the shaping and clamping linear module 3022 is lifted and fixed to the shaping and clamping member 3021, so that the shaping and clamping linear module 3022 drives the shaping and clamping member 3021 to be pressed on the battery cell, and the movement of the battery cell during the shaping process is restricted to ensure the smooth shaping of the end face of the battery cell. Specifically, the shaping and clamping linear module 3022 includes an electric cylinder to firmly clamp the pole ear. In other embodiments, the shaping and clamping linear module 3022 may also include a screw mechanism or a linear motor.

[0064] The embodiment of the present application provides a battery cell end face shaping device. When the battery cell end face is shaped, it is driven by a conveying mechanism 1 and passes through multiple shaping modules 2 in sequence, and the multiple shaping modules 2 shape the end face of the battery cell in sequence, wherein the shaping surface 201a of the shaping component 201 is used to press the pole ear at the end of the battery cell so that the pole ear at the end of the battery cell is attached to the shaping surface 201a. Since the angle between the multiple shaping surfaces 201a and the cross section of the battery cell gradually decreases along the conveying direction of the battery cell, after the end face of the battery cell is shaped multiple times, the length of the pole ear at the end of the battery cell protruding from the end face of the battery cell gradually decreases, and finally adheres to the end face of the battery cell, thereby completing the shaping process of the battery cell end face. Since the pole ear at the end of the battery cell has been shaped multiple times, each shaping process causes a smaller deformation to the pole ear at the end of the battery cell, so the pole ear of the battery cell is not easily damaged and will not fall off, thereby ensuring the processing quality of the battery cell, and the pole ear is more tightly attached, thereby improving the effect of the shaping of the battery cell end face.

[0065] Another embodiment of the present application provides a method for shaping a cell end face, based on the cell end face shaping device described above, comprising the following steps:

[0066] Fold in the tabs at the ends of the battery cell.

[0067] The tabs at the ends of the battery cells are pressed repeatedly, so that the angle between the tabs at the end faces of the battery cells and the cross section of the battery cells is gradually reduced.

[0068] Flatten the tabs at the ends of the battery cells so that they fit snugly against the end faces of the cells.
