[0002] In recent years, lithium-ion batteries have developed rapidly and are widely used in the field of new energy vehicles. Among them, lithium-ion batteries need to go through the cover plate buckle process during the production process. The cover plate buckle process is to buckle the cover plate with the battery body to form a complete battery. The main function of the buckle cover plate is to protect the internal structure and electrochemical reaction of the battery from the influence of the external environment, and at the same time, it can also prevent safety hazards such as short circuit and overcharging.

The buckling strength needs to be strengthened by a secondary cover buckling, and the operation process is complicated. Utility Model Content

[0004] The present application provides a battery processing device, which can reduce the complex actions when the cover plate is fastened and improve the fastening strength of the cover plate through the cooperation of the fastening mechanism and the first track.

[0005] In a first aspect, the present application provides a battery processing device for buckling a cover plate onto a battery cell, the battery processing device comprising a transport mechanism, a buckling mechanism, and a first track. The transport mechanism is used to transport the cover plate and the battery cell; the buckling mechanism is located on the transport mechanism and moves along a first direction with the transport mechanism, and the buckling mechanism is used to fix the cover plate and the battery cell; the first track is located on a side of the first track facing the transport mechanism, the buckling mechanism slides on the first track, at least a portion of the first track is tilted along the first direction toward the transport mechanism, and at least a portion of the first track is used to push the buckling mechanism to move in a direction close to the transport mechanism.

[0006] The battery processing device provided by the present application fastens the cover plate on the battery cell by setting a fastening mechanism and a first track. When at least part of the first track is tilted in the first direction toward the transport mechanism, the first track can push the fastening mechanism to move in the direction close to the transport mechanism. During the process of fastening the cover plate, the first track applies an extrusion force toward the cover plate to the fastening mechanism to strengthen the fastening strength between the cover plate and the battery cell, so that the cover plate can be fastened to the battery cell more firmly, avoiding displacement or loosening of the cover plate due to bumps or other external forces during transportation by the transport mechanism. In addition, a large number of executive components in the process of fastening the cover plate are reduced, production efficiency is improved, and equipment stability is improved.

[0007] In one possible implementation, the first track includes a first track surface and a second track surface, the first track surface is used to be set at a first distance from the battery cell, and the first distance gradually decreases along the first direction, the second track surface is used to be set at a second distance from the battery cell, and the second distance remains unchanged along the first direction, and the first direction is the transportation direction of the battery cell on the transportation mechanism.

[0008] The first track surface is set at a first distance from the battery cell, and the first distance gradually decreases along the first direction, so that the buckling mechanism moves toward the battery cell, which is conducive to the buckling of the cover. The second track surface is set at a second distance from the battery cell, and the second distance remains unchanged along the first direction, so that the buckling mechanism moves toward the thickness direction of the battery cell, which can limit the buckling position of the cover.

[0009] In one possible implementation, the locking mechanism includes a first roller and a first movable member, the first roller is used to move along the first track, the first movable member is located on a side of the first roller away from the first track, and the first roller is used to push the first movable member to move in a direction away from the first track.

[0010] When the first roller moves along the first direction on the first track surface, the first distance gradually decreases, and the first track surface causes the snapping mechanism to gradually move toward the direction of the battery cell, so that the cover is snapped onto the battery cell. When the first roller moves to the second track surface, the adjusting member moves toward the direction of the battery cell driven by the first roller, thereby pushing the second moving member body to move toward the thickness direction of the battery cell. When the first roller moves to the third track surface, the third distance gradually increases, the snapping mechanism moves in the direction away from the battery cell, and the snapping mechanism gradually resets and enters the next first track.

[0011] In a possible implementation, the buckling mechanism includes an adjusting member, the adjusting member has a first adjusting surface and a second adjusting surface, the first adjusting surface has a first height from the top of the adjusting member, the second adjusting surface has a second height from the top of the adjusting member, and the first height is less than the second height.

The second roller moves on the adjustment member, and can drive the second moving member body to move, thereby limiting the thickness direction of the battery cell.

[0013] In a possible implementation, the locking mechanism further includes a connecting member, and the connecting member is used to connect the first moving member and the second moving member.

[0014] In a possible implementation, the battery processing device further includes a clamp, the clamp is located on the transport mechanism, the clamp includes a carrier plate, the carrier plate is used to carry the battery cell and the cover plate, the buckling mechanism is fixed to both ends of the carrier plate along a second direction, and the second direction is perpendicular to the first direction. The cover plate is located between the battery cell and the buckling mechanism, and the buckling mechanism buckles the cover plate and the battery cell located on the carrier plate.

[0015] In a possible implementation, the clamp further includes a clamping member connected to the carrier plate, the number of the clamping member is at least one, and the clamping member is used to clamp the battery cell. The clamping member can keep the battery cell stable on the clamp.

[0017] When the third roller of the battery cell shielding mechanism is not in contact with the second track, the battery cell shielding mechanism is close to the side of the battery cell and can ensure the relative position of the cover plate and the battery cell. When the third roller moves on the second track, the third roller can push the battery cell shielding mechanism to move along the width direction of the battery cell toward the side away from the battery cell, creating a gap with the cover plate, which can facilitate the tilting of the cover plate.

[0035] The present application provides a battery processing device 10, which is used to buckle the cover plate on the battery cell during the battery production process, and buckle the cover plate on the battery cell. The buckle cover plate process is to buckle the cover plate with the battery body to form a complete battery. The buckle cover plate mainly protects the internal structure and electrochemical reaction of the battery from the influence of the external environment, and also prevents safety hazards such as short circuit and overcharging.

[0036] See also Figure 1 and Figure 2As shown, the battery processing device 10 includes a transport mechanism 110, a fastening mechanism 120 and a first track 130. The transport mechanism 110 is used to transport the cover plate 30, the battery cell 20 and the fastening mechanism 120. The fastening mechanism 120 is located on the transport mechanism 110 and moves along the first direction with the transport mechanism 110. The fastening mechanism 120 is used to fix the cover plate 30 and the battery cell 20. In the embodiment of the present application, the transport mechanism 110 is a ring-shaped circulation transport mechanism, and the transport mechanism can move along the first direction ( Figure 1 The positive direction of the Y direction) is used for transportation.

[0037] It is understandable that the transport mechanism 110 includes but is not limited to a vertical circular transport mechanism and a flat circular transport mechanism. The types of the transport mechanism 110 include but are not limited to a magnetic levitation transport mechanism, a belt transport mechanism, a chain transport mechanism, and a helical gear transport mechanism.

[0038] The buckling mechanism 120 is located on the side of the first track 130 facing the transport mechanism 110, and the buckling mechanism 120 slides on the first track 130. At least part of the first track 130 is inclined in a first direction toward the transport mechanism 110, and at least part of the first track 130 is used to push the buckling mechanism 120 to move in a direction close to the transport mechanism 110. There are at least two first tracks 130, and the two first tracks 130 are respectively located on both sides of the buckling mechanism 120. It can be understood that in some possible embodiments, the number of the first tracks 130 can also be other numbers, and the present application is not limited here.

[0039] The cover plate 30 and the battery cell 20 are located on one side of the buckling mechanism 120, and the cover plate 30 is located between the battery cell 20 and the buckling mechanism 120. The buckling mechanism 120 pushes the cover plate 30 toward the battery cell 20 ( Figure 1 The cover plate 30 is moved in the positive direction of the X direction in the figure to buckle the cover plate 30 onto the battery cell 20.

[0040] The first track 130 is used to move along a first direction ( Figure 1 The first track 130 is used to cooperate with the buckling mechanism 120 to buckle the cover plate 30 on the battery cell 20. Figure 1 The battery processing device 10 provided is taken as an example to illustrate the buckle cover plate function of the device.

[0041] See also Figure 1As shown, a first track 130 is provided on one side of the buckling mechanism 120, and the buckling mechanism 120 is located between the battery cell 20 and the first track 130. There are two buckling mechanisms 120 and two first tracks 130. When the transport mechanism 110 is transported in the first direction, the transport mechanism 110 drives the buckling mechanism 120 to move together. The buckling mechanism 120 moves on the first track 130 along the direction of transportation of the transport mechanism 110. The first track 130 is inclined toward the battery cell 20 along the first direction, and the first track 130 can apply an extrusion force toward the cover plate 30 to the buckling mechanism 120. The extrusion force applied by the first track 130 to the buckling mechanism 120 can ensure that the buckling mechanism 120 is tightly attached to the cover plate 30, completing the action of buckling the cover plate. The first track 130 cooperates with the buckling mechanism 120 to buckle the cover plate 30 on the battery cell 20 until entering the next process.

[0042] The battery processing device 10 provided in the present application fastens the cover plate 30 on the battery cell 20 by setting a fastening mechanism 120 and a first track 130, and further utilizes the cooperation of the first track 130 and the fastening mechanism 120 to apply an extrusion force toward the cover plate 30 to the fastening mechanism 120. After the cover plate 30 is fastened to the battery cell 20, the first track 130 enables the cover plate 30 to strengthen the fastening strength between the cover plate 30 and the battery cell 20, so that the cover plate 30 can be fastened to the battery cell 20 more firmly, avoiding displacement or loosening of the cover plate 30 due to bumps or other external forces during transportation by the transportation mechanism 110. In addition, a large number of executive components in the process of fastening the cover plate are reduced, production efficiency is improved, and equipment stability performance is improved.

[0043] In one possible implementation, see Figure 1 As shown, the battery processing device 10 includes a support plate 150, the support plate 150 passes through the center of the transport mechanism 110, and the first rail 130 is fixed on the support plate 150. Figure 2 As shown, the first track 130 includes a first track surface 131, a second track surface 132 and a third track surface 133. The first track surface 131 is spaced a first distance L1 from the battery cell 20. The first distance L1 is along the first direction ( Figure 2 The second track surface 132 is set at a second distance L2 from the battery cell 20, and the second distance L2 remains unchanged along the first direction. The third track surface 133 is set at a third distance L3 from the battery cell 20, and the third distance L3 gradually increases along the first direction.

[0044] In a possible embodiment, the snap-fit ​​mechanism 120 includes a first roller 121 and a first movable member 122, the first roller 121 is used to move along the first track 130, the first movable member 122 is located on the side of the first roller 121 away from the first track 130, and the first roller 121 is used to push the first movable member 122 to move in a direction away from the first track 130.

[0045] See also Figure 3 and Figure 4 As shown, the locking mechanism 120 includes a first roller 121 and a first moving member 122. The first roller 121 can be fixed on a roller fixing member 126. The roller fixing member 126 and the first moving member 122 can be connected via a first spring 127. The first moving member 122 is located on a side of the first roller 121 away from the first track 130, that is, the first roller 121 is located between the first track 130 and the first moving member 122.

[0046] When the fastening mechanism 120 moves to the first track 130 along with the transport mechanism 110, the first track 130 first contacts the first roller 121 of the fastening mechanism 120, and the first track 130 makes the first roller 121 face the direction of the battery cell 20 ( Figure 3 The first roller 121 drives the roller fixing member 126 to move toward the battery cell 20. Further, the roller fixing member 126 compresses the first spring 127, and the first spring 127 pushes the first moving member 122 to move toward the battery cell 20. The cover plate 30 is located between the first moving member 122 and the battery cell 20. The cover plate 30 is buckled on the battery cell 20 during the movement of the first moving member 122 toward the battery cell 20.

[0047] In one possible implementation, see Figure 3 and Figure 5 As shown, the locking mechanism 120 further includes an adjusting member 124, and the adjusting member 124 is fixedly connected to the roller fixing member 126, so that the roller fixing member 126 can drive the adjusting member 124 to move during its movement. Figure 5 As shown, the adjusting member 124 has a first adjusting surface 1241 and a second adjusting surface 1242. The first adjusting surface 1241 has a first height H1 from the top of the adjusting member 124. The first height H1 is the vertical distance from the top of the adjusting member 124 to the first adjusting surface 1241. The second adjusting surface 1242 has a second height H2 from the adjusting member 124. The second height H2 is the vertical distance from the top of the adjusting member 124 to the second adjusting surface 1242. The first height H1 is less than the second height H2. For example, Figure 5In the embodiment, the first adjustment surface 1241 and the second adjustment surface 1242 form a structure similar to a step. When the first roller 121 moves on the first track 130, the adjustment member 124 can adjust the buckling mechanism 120 in a direction perpendicular to the direction of the battery cell 20 ( Figure 3 The height in the opposite direction of the Z direction) can better limit the snap-fit ​​mechanism 120, so that the cover plate 30 can be better snap-fitted on the battery cell 20.

[0048] In a possible embodiment, the snap-fit ​​mechanism 120 also includes a second moving member 123, and the second moving member 123 includes a second roller 1231 and a second moving member body 1232. The second roller 1231 is located on the second moving member body 1232, for example, the second roller 1231 can be located at both ends of the second moving member body 1232. The second roller 1231 can push the second moving member body 1232 to move. Specifically, the second moving member 123 is located between the first moving member 122 and the cover plate 30. The second roller 1231 can move on the first adjustment surface 1241 and the second adjustment surface 1242 of the adjusting member 124. The second roller 1231 is used to push the second moving member body 1232 toward the thickness direction ( Figure 3 Move in the opposite direction of the Z direction).

[0049] Specifically, as the first roller 121 moves on the first track 130, the roller fixing member 126 drives the adjusting member 124 to move toward the battery cell 20. In the process of the adjusting member 124 moving toward the battery cell 20, the second roller 1231 first moves on the first adjusting surface 1241, and then moves on the second adjusting surface 1242. The second height H2 of the second adjusting surface 1242 from the top of the adjusting member 124 is greater than the first height H1 of the first adjusting surface 1241 from the top of the adjusting member 124, and there is a height difference between the second adjusting surface 1242 and the first adjusting surface 1241, so that when the second roller 1231 moves from the first adjusting surface 1241 to the second adjusting surface 1242, the second roller 1231 moves in the thickness direction ( Figure 3 The second roller 1231 drives the second moving member body 1232 to move in the thickness direction (opposite direction of the Z direction) of the battery cell 20. Figure 3 The second moving member 123 moves in the opposite direction of the Z direction, and then the second moving member 123 is close to the battery cell 20 in the thickness direction of the battery cell 20, which can limit the engagement between the cover plate 30 and the battery cell 20.

[0050] In one possible implementation, see Figure 3 and Figure 5As shown, there is a connecting member 125 between the first moving member 122 and the second moving member, and the connecting member 125 is used to connect the first moving member 122 and the second moving member 123. In one embodiment, the connecting member 125 can be a second spring, and when the second roller 1231 moves from the first adjustment surface 1241 to the second adjustment surface 1242, the second moving member body 1232 moves in the thickness direction of the battery cell 20, and the second spring is in a stretched state; when the second roller 1231 moves from the second adjustment surface 1242 to the first adjustment surface 1241, the second moving member body 1232 moves in the thickness direction of the battery cell 20, and the second spring is reset from the stretched state.

[0051] When the first roller 121 moves along the first direction of the battery cell 20 on the first track surface 131, the first distance L1 gradually decreases, and the first track surface 131 causes the locking mechanism 120 to gradually move toward the direction of the battery cell ( Figure 2 When the first roller 121 continues to move onto the second track surface 132, the adjusting member 124 moves toward the direction of the battery cell 20 (the opposite direction of the X direction in FIG. 1 ). Figure 3 The second roller 1231 contacts the second adjustment surface 1242, pushing the second moving member body 1232 along the thickness direction ( Figure 3 At this time, the battery cell 20 has limited positions in both the X direction and the Z direction, which can ensure that the cover plate 30 is accurately buckled into the battery cell 20. When the first roller 121 moves to the third track surface 133, the third distance L3 gradually increases, and the buckling mechanism 120 moves in the direction away from the battery cell 20 ( Figure 2 The buckling mechanism 120 moves in the X direction in the middle of the battery cell 20, and the buckling mechanism 120 gradually resets and enters the next first track 130. The buckling mechanism 120 keeps moving on the first track 130, and the first track 130 applies a squeezing force to the buckling mechanism 120, so that the buckling mechanism 120 can keep pressing the cover plate 30, ensuring that the cover plate 30 can be firmly buckled on the battery cell 20 until entering the next process.

[0052] In one possible implementation, see Figure 1 As shown, the battery processing device 10 also includes a clamp 140, which is located on the transportation mechanism 110. The clamp 140 includes a carrier plate 141, which is used to carry the battery cell 20 and the cover plate 30. The snap-fit ​​mechanism 120 is fixed to both ends of the carrier plate 141 along the second direction, and the second direction is perpendicular to the first direction.

[0053] See also Figure 6As shown, the clamp 140 includes a snap-fit ​​mechanism 120, which is used to snap the cover plate 30 onto the battery cell 20. When the battery processing device 10 is working, the cover plate 30 is located between the battery cell 20 and the snap-fit ​​mechanism 120, and the snap-fit ​​mechanism 120 pushes the cover plate 30 to move toward the battery cell 20 to snap the cover plate 30 onto the battery cell 20. There are at least two snap-fit ​​mechanisms 120. In the embodiment of the present application, the number of snap-fit ​​mechanisms 120 is two, and the snap-fit ​​mechanisms 120 can be located at both ends of the clamp 140. The two snap-fit ​​mechanisms 120 can be symmetrically arranged at both ends of the clamp 140. The cover plate 30 is located between the battery cell 20 and the snap-fit ​​mechanism 120. It can be understood that in some possible embodiments, the number of the snap-fit ​​mechanisms 120 can also be other numbers, and the snap-fit ​​mechanisms 120 can also be located at both ends of the clamp 140 and the middle of the clamp, which is not limited in the present application.

[0054] In one possible implementation, see Figure 6 As shown, the clamp 140 also includes a clamp 142, the number of the clamp 142 is at least one, and the clamp 142 is located along the width direction ( Figure 6 The clamping member 142 is used to clamp the battery cell 20. In the embodiment of the present application, there are two clamping members 142, which can make the clamping of the battery cell 20 on the clamping member 142 more stable.

[0055] In a possible implementation manner, the fixture 140 further includes a stopper 143, the stopper 143 is located on the carrier 141, and the stopper 143 is used to limit the first moving member 122 from moving toward the battery cell 20 ( Figure 6 When the first moving member 122 contacts the stopper 143, the first moving member 122 stops moving, and the second roller 1231 continues to move toward the direction of the battery cell 20 ( Figure 6 The second roller 1231 can move on the first adjustment surface 1241 and the second adjustment surface 1242 of the adjustment member 124, and then push the second moving member body 1232 toward the thickness direction of the battery cell 20 ( Figure 3 Move in the opposite direction of the Z direction).

[0056] In a possible implementation, the clamp 140 further includes a cell protection shell mechanism 144, which includes a pusher 1441 and a cell protection shell 1442. The pusher 1441 includes a third roller 1441a and a push rod 1441b, the third roller 1441a is used to move on the second track 170 and drive the push rod 1441b to move along the first direction, and the second track 170 is located on the side of the clamp 140 away from the buckle mechanism 120; the cell protection shell 1442 is used to be arranged on both sides of the cell 20 along the first direction, and the push rod 1441b is used to push the cell protection shell 1442 to move along the first direction.

[0057] When the third roller 1441a is not in contact with the second track 170, the battery cell protection mechanism 144 is in a natural state. The third spring 1443 of the battery cell protection mechanism 144 provides power, and the limit block 1444 provides a reference, so that the battery cell protection mechanism 144 is close to the side of the battery cell 20 and can ensure the relative position of the cover plate 30 and the battery cell 20. When the battery cell protection mechanism 144 is close to the side of the battery cell 20, when the cover plate 30 is subjected to external force, the cover plate 30 is subjected to the battery cell protection mechanism 144 along the width direction of the battery cell 20 ( Figure 7 The battery cell 20 is pressed in the X direction, and is not easily flipped or tilted.

[0058] When the third roller 1441a moves on the second track 170, it can drive the push rod 1441b to move along the Figure 7 The push rod 1441b moves in the X direction, and then the third spring 1443 is compressed and pushes the battery cell shield 1442 along the width direction of the battery cell 20 ( Figure 7 The battery cell protection shell 1442 is pushed by the push rod 1441b to form a gap with the cover plate 30, so that the cover plate 30 can be tilted.

[0059] In one possible implementation, see Figure 1 and Figure 8As shown, the battery processing device 10 also includes a support plate 150 and a pole ear folding mechanism 160. The pole ear folding mechanism 160 and the first track 130 are both fixed on the support plate 150. The pole ear folding mechanism 160 is located at both ends of the clamp 140 along the second direction. The pole ear folding mechanism 160 and the first track 130 are adjacently arranged along the first direction. The snap-fit ​​mechanism 120 contacts the pole ear folding mechanism 160 and the first track 130 in sequence along the first direction. The pole ear folding mechanism 160 includes a cover plate flipping member 161, a first folding knife 162, a second folding knife 163 and a cover plate stopper 164. The pole ear folding mechanism 160 is used to bend the pole ear of the battery cell 20. The pole ear folding process refers to the bending operation of the pole ear in the battery production and processing, so that the bent pole ear can be attached to the battery housing, which is convenient for subsequent processing. In the embodiment of the present application, the pole ear 210 of the battery cell 20 is located at the short side of the battery cell 20, and the battery cell 20 has two pole ears 210.

[0060] The cover flip member 161 is used to rotate along the thickness direction ( Figure 8 When the fixture 140 is transported to the electrode folding mechanism 160, the cover plate flipping member 161 of the electrode folding mechanism 160 moves along the thickness direction (Z direction) of the support plate 150. Figure 8 The cover flipping member 161 can move in the Z direction in the middle, so that the cover 30 can be tilted.

[0061] The first folding knife 162 is spaced apart from the cover plate 30 along the thickness direction of the support plate 150, and the first folding knife 162 is used to move along the thickness direction of the support plate 150. Figure 8 After the push in the positive direction of the Z direction inclination occurs, the first folding knife 162 moves along Figure 8 The first folding knife 162 moves in the opposite direction of the Z direction, and contacts the tilted cover plate 30, so that the tilted cover plate 30 is maintained at this position.

[0062] The second folding knife 163 is tilted relative to the support plate 150, and the second folding knife 163 is used to bend the tab 210 of the battery cell 20. Figure 8 When the cover plate 30 is moved in the opposite direction of the Z direction to maintain the position of the inclined cover plate 30 unchanged, a gap is generated between the inclined cover plate 30 and the battery cell 20, and the second folding knife 163 extends into the gap between the cover plate 30 and the battery cell 20 along its own inclined setting direction, applying a crease to the pole ear 210, thereby bending the pole ear 210.

[0063] Further, the cover plate stopper 143 is along Figure 8As the transport mechanism 110 drives the buckling mechanism 120 to move along the first direction, the buckling mechanism 120 cooperates with the first track 130 to gradually transform the inclined cover plate 30 into an upright state and buckle on the battery cell 20.

[0064] The battery processing device 10 provided by the present application can simultaneously complete the process of folding the pole ear and buckling the cover plate of the battery cell 20, reducing the complex design of the actuator element, and realizing the continuous conveying of the transport mechanism to complete the folding of the pole ear and buckling of the cover plate during the moving process, thereby shortening the product production time and improving the production efficiency. The clamp 140 does not need to be loosened during the entire production process, ensuring the consistency of the position of the battery cell 20 during the production process, and there is no need to repeat the positioning work.
