Description

Technical Field

[0001] The present invention relates to the technical field of battery packs, and particularly to a stacking and fastening device for square battery packs. Background Art

[0002] A battery pack refers to a battery system formed by combining multiple single cells in series or parallel. Each single cell is composed of a positive electrode, a negative electrode, a separator, and an electrolyte. In a series battery pack, the single cells are connected in sequence to form a higher voltage; in a parallel battery pack, the voltage of each single cell is the same, and they jointly provide a stronger current.

[0003] However, in actual use, we found that during the stacking and fastening process of existing square battery packs, steel bars are usually used to bundle multiple batteries. The operation process is usually to stack the square batteries first, then through extrusion to reduce the distance between multiple batteries, and then the steel bar located below the battery pack is controlled by a machine to be stuck outside multiple batteries, and then a steel bar is manually placed outside multiple batteries, so that multiple batteries are fastened under the action of the two steel bars to generate a battery pack. However, this method cannot be completely separated from manual work, and while the operation is cumbersome, it still brings a large workload to the staff and cannot guarantee the stacking and fastening production efficiency of the battery pack.

The flipping steel bar sleeving assembly 6 is used to control the rotation of the multiple upper steel bars 5 and sleeved them on the outer side of the battery pack body 2 one by one in sequence to fasten the battery pack body 2;

[0045] The linkage steel bar sleeving assembly 7 is arranged below and above the workbench 1. The linkage steel bar sleeving assembly 7 is used to control the automatic feeding of the multiple lower steel bars 4 and sleeved the multiple lower steel bars 4 on the outer side of the battery pack body 2 one by one in sequence to assist the corresponding upper steel bars 5 to fasten the battery pack body 2.

[0046] The flipping steel bar sleeving assembly 6 includes a rotating member 8 arranged on the workbench 1. The rotating member 8 is used to control the rotation of the multiple upper steel bars 5 so that the multiple upper steel bars 5 are located directly above the battery pack body 2. There are multiple control members 9 arranged above the workbench 1. The multiple control members 9 are used to control the multiple upper steel bars 5 to be sleeved on the outer side of the battery pack body 2 one by one in the arranged order. There is a discharging member 10 arranged above the workbench 1, and the discharging member 10 is used in cooperation with the corresponding multiple control members 9 to control the multiple upper steel bars 5 to be sleeved on the outer side of the battery pack body 2 one by one in the sorted order.

[0047] The rotating member 8 includes a first support rod 81 arranged on the workbench 1. A first guiding groove 82 is formed in the first support rod 81. A guiding rod 83 is arranged in the first guiding groove 82. A first rotating rod 84 is rotatably arranged in the first guiding groove 82, and the first rotating rod 84 is rotatably arranged on the top of the guiding rod 83. A groove 85 matching with the guiding rod 83 is formed in the first rotating rod 84. A first supporting plate 86 is slidably arranged in the first guiding groove 82. The first supporting plate 86 is slidably arranged on the outer side of the guiding rod 83. A first reset spring 87 is arranged at the bottom of the first supporting plate 86. One end of the first reset spring 87 away from the first supporting plate 86 is arranged at the bottom of the first guiding groove 82. One end of the first rotating rod 84 close to the battery pack body 2 is provided with a cover plate 88. The multiple upper steel bars 5 are all slidably arranged in the cover plate 88. One end of the first rotating rod 84 away from the cover plate 88 is provided with a first magnet 89. A second magnet 810 matching with the first magnet 89 is arranged on the outer side of the first support rod 81;

[0048] One end of the cover plate 88 away from the first rotating rod 84 is provided with a second rotating rod 811. A second support rod 812 is arranged on the workbench 1. A second guiding groove 813 which is matched with the second rotating rod 811 is formed in the second support rod 812. A second supporting plate 814 is slidably arranged in the second guiding groove 813. A second reset spring 815 is arranged at the bottom of the second supporting plate 814. One end of the second reset spring 815 away from the second supporting plate 814 is arranged at the bottom of the second guiding groove 813. When the steel strip 5 needs to be sleeved on the battery pack body 2, by rotating the cover plate 88, the cover plate 88 will rotate in the first support rod 81 through the first rotating rod 84 at one end thereof, and the plurality of steel strips 5 slidably arranged in the cover plate 88 will move together with the cover plate 88. When the cover plate 88 drives the first rotating rod 84 to rotate to a state parallel to the surface of the workbench 1, the second rotating rod 811 will be in contact with the second supporting plate 814, and the groove 85 formed in the first rotating rod 84 will be aligned with the guiding rod 83. At this time, press down the cover plate 88, so that the first rotating rod 84 and the second rotating rod 811 arranged on one side of the cover plate 88 respectively slide in the corresponding first guiding groove 82 and the second guiding groove 813. The groove 85 formed in the first rotating rod 84 can control the first rotating rod 84 not to slide in the first guiding groove 82 when the cover plate 88 is not in a state parallel to the workbench 1, so that the rotating rod can only rotate in the first guiding groove 82 and on the top of the guiding rod 83. When the cover plate 88 is pressed down, the groove 85 in the first rotating rod 84 slides on the outside of the guiding rod 83, and the first rotating rod 84 and the second rotating rod 811 will make the corresponding first supporting plate 86 and the second supporting plate 814 move downward, and the first reset spring 87 and the second reset spring 815 respectively arranged at the bottoms of the first supporting plate 86 and the second supporting plate 814 start to be compressed. The first reset spring 87 and the second reset spring 815 can control the cover plate 88 to rise when the cover plate 88 is not affected by an external force. When the cover plate 88 is retracted, a first magnet 89 arranged at one end of the first rotating rod 84 will be adsorbed to a second magnet 810 on one side of the first support rod 81, so as to position the angle of the cover plate 88 and avoid affecting the subsequent operation on the battery pack body 2. Its function is to be able to control the angle of the cover plate 88 after rotation through the cooperation of the groove 85 and the guiding rod 83, and ensure that the steel strip 5 in the cover plate 88 is perpendicular to the battery pack body 2 before being sleeved on the outside of the battery pack body 2, which is convenient for the subsequent sleeving of the steel strip 5.

[0049] The control member 9 includes a baffle 91 slidably arranged in the cover plate 88, and the baffle 91 is located between the plurality of steel strips 5 and the opening of the cover plate 88. A stop rod 92 is arranged at the top of the baffle 91. A first control spring 93 is arranged on the outside of the stop rod 92. A first control frame 94 which is matched with the stop rod 92 is arranged on the top of the cover plate 88. The stop rod 92 is slidably arranged in the first control frame 94. The top of the first control spring 93 is arranged on the first control frame 94, and the other end thereof is arranged at the top of the baffle 91.

When the discharging block two 108 presses the discharging groove two 105 on the pressing plate 95, the inclined surface on one side of the discharging block two 108 will control the movement of the pressing plate 95 through the discharging groove two 105, so that the pressing plate 95 presses the upper steel bar 5 on one side thereof, thereby fixing the position of the adjacent upper steel bar 5. When the second telescopic plate 107 slides inside the first telescopic plate 106 and the delay spring 109 starts to be compressed, the discharging block one 104 will enter the discharging groove one 103 inside the baffle 91 and press the baffle 91 through the discharging groove one 103, so that the baffle 91 is separated from the restriction on the upper steel bar 5 on one side thereof, thereby enabling the upper steel bar 5 closest to the opening of the cover plate 88 to be separated from the cover plate 88 and sleeved on the outer side of the battery pack body 2. When the worker releases the pressing on the cover plate 88, the discharging block one 104 will first be separated from the discharging groove one 103. The stop rod 92 arranged on the outer side of the baffle 91 will be controlled to reset under the action of the first control spring 93, so that the stop rod 92 pushes the baffle 91 to intercept the previous upper steel bar 5. When the discharging block one 104 is completely separated from the discharging groove one 103 and the delay spring 109 controls the first telescopic plate 106 and the second telescopic plate 107 to reset, the discharging block two 108 will gradually be separated from the discharging groove two 105. At this time, the pressing rod 97 on one side of the pressing plate 95 will slide inside the second control frame 96 under the action of the second control spring 98, so that the pressing plate 95 is separated from the pressing on the upper steel bar 5, and the upper steel bar 5 separated from the pressing of the pressing plate 95 will fall above the baffle 91 to prepare for the next sleeving of the upper steel bar 5. Its function is to be able to sleeve multiple upper steel bars 5 in an orderly manner, only sleeve one upper steel bar 5 on the outer side of the battery pack body 2 each time, and automatically prepare for the next sleeving of the upper steel bar 5.

A first telescopic plate 106 is arranged on the top of each of the plurality of first discharging blocks 104, a second telescopic plate 107 is slidably arranged in each of the plurality of first telescopic plates 106, and a second discharging block 108 that cooperates with the plurality of second discharging grooves 105 is arranged on the top of each of the plurality of second telescopic plates 107. The side of each of the plurality of discharging blocks close to the battery pack body 2 is an inclined surface. A delay spring 109 is arranged on the top of each of the plurality of first discharging blocks 104, and the top ends of the plurality of delay springs 109 are arranged at the bottom of the corresponding second discharging blocks 108. When the cover plate 88 is pressed down, the first discharging blocks 104 and the second discharging blocks 108 arranged on the discharging racks 101 will enter the corresponding auxiliary grooves 102. The second discharging block 108 located above the first discharging block 104 will first enter the auxiliary groove 102 and penetrate through the first discharging groove 103 to squeeze the second discharging groove 105 on the pressing plate 95. During the process of the second discharging block 108 squeezing the second discharging groove 105, the delay spring 109 will maintain the distance between the first discharging block 104 and the second discharging block 108 to prevent the first discharging block 104 from entering the first discharging groove 103 after the second discharging block 108 has not completed the squeezing of the pressing plate 95. After the second discharging block 108 has completed the squeezing of the second discharging groove 105, the second telescopic plate 107 will slide in the first telescopic plate 106, causing the first discharging block 104 to approach the second discharging block 108. At this time, the first discharging block 104 will squeeze the baffle 91 through the first discharging groove 103. Its function is to be able to control the sequential movement of the pressing plate 95 and the baffle 91 respectively in sequence.

A synchronizing plate 123 is arranged at the bottom of the plurality of top plates 121. A blanking spring 124 is arranged at the top of the synchronizing plate 123. An auxiliary frame 125 is arranged at the top of the blanking spring 124. The top of the auxiliary frame 125 is arranged at the bottom of the workbench 1. When the synchronizing plate 123 moves upward under the action of the transmission rope 132, the synchronizing plate 123 will drive the plurality of top plates 121 at its top to move upward together. The upward-moving top plates 121 will push the lower steel bars 4 in the material storage grooves 113, so that the lower steel bars 4 located in the material storage grooves 113 are sleeved outside the battery pack body 2. The blanking grooves 122 formed in the top plates 121 can be completely in fit with the material storage grooves 113, and will not affect the feeding process of the lower steel bars 4. When the synchronizing plate 123 is not controlled by an external force, the blanking spring 124 arranged at the top of the synchronizing plate 123 will control the synchronizing plate 123 to reset. Its function is to control the simultaneous movement of the plurality of top plates 121 through the synchronizing plate 123.

[0055] The transmission part 13 includes a transmission rod 131 arranged at the bottom of the second support plate 814. The transmission rod 131 penetrates and is slidably arranged in the workbench 1. A transmission rope 132 is arranged at the bottom of the transmission rod 131. A first steering rod 133 is arranged at the bottom of the workbench 1.

The transmission rope 132 penetrates through the axles of the first steering rod 133, the second steering rod 134 and the auxiliary frame 125, and extends to the top of the synchronizing plate 123. When the cover plate 88 is pressed down, the rotating rod two 811 on one side of the cover plate 88 will squeeze the second support plate 814 which is used in cooperation with it, so that the second support plate 814 moves downward. The downward-moving second support plate 814 will drive the transmission rod 131 at its bottom to move downward, so that the transmission rod 131 slides in the workbench 1. The downward-moving transmission rod 131 will pull one end of the transmission rope 132, so that the synchronizing plate 123 at the other end of the transmission rope 132 moves upward under the action of the second steering rod 134. The second steering rod 134 can change the horizontal force of the transmission rope 132 into an upward force, and the first steering rod 133 can prevent the transmission rope 132 from affecting the top plate 121 during the pulling process. Its function is to change the downward force of the transmission rope 132 into a force for controlling the synchronizing plate 123 to move upward and drive the synchronizing plate 123 to move.

[0056] In use, after the staff places the battery pack body 2 on the replenishing plate 114 on the workbench 1, the battery pack body 2 is extruded by the extrusion system 3. The extrusion system 3 is a prior art and will not be elaborated here. When it is necessary to sleeved the steel strip 5 on the battery pack body 2, by rotating the cover plate 88, the cover plate 88 will rotate in the support rod 81 through the rotating rod 84 at one end thereof, and a plurality of steel strips 5 slidably arranged in the cover plate 88 will move together with the cover plate 88. When the cover plate 88 drives the rotating rod 84 to rotate to a state parallel to the surface of the workbench 1, the rotating rod 811 will be in contact with the supporting plate 814, and the groove 85 formed in the rotating rod 84 will be aligned with the guiding rod 83. At this time, the cover plate 88 is pressed down, so that the rotating rod 84 and the rotating rod 811 arranged on one side of the cover plate 88 slide in the corresponding guiding groove 82 and guiding groove 813 respectively. The groove 85 formed in the rotating rod 84 can control the rotating rod 84 not to slide in the guiding groove 82 when the cover plate 88 is not in a state parallel to the workbench 1, so that the rotating rod can only rotate in the guiding groove 82 and on the top of the guiding rod 83. When the cover plate 88 is pressed down, the groove 85 in the rotating rod 84 slides on the outside of the guiding rod 83, and the rotating rod 84 and the rotating rod 811 will cause the corresponding supporting plate 86 and supporting plate 814 to move downward, and the return springs 87 and return spring 815 respectively arranged at the bottoms of the supporting plate 86 and supporting plate 814 start to be compressed. The return springs 87 and return spring 815 can control the cover plate 88 to rise when the cover plate 88 is not subject to external force. When the cover plate 88 is retracted, the magnet 89 arranged at one end of the rotating rod 84 will be adsorbed to the magnet 810 on one side of the support rod 81, so as to position the angle of the cover plate 88 and avoid affecting the subsequent operation on the battery pack body 2;

[0057] When the cover plate 88 is pressed down, the first discharge block 104 and the second discharge block 108 provided on the discharge rack 101 will enter the corresponding auxiliary grooves 102. The second discharge block 108 located above the first discharge block 104 will enter the auxiliary groove 102 first and penetrate through the first discharge groove 103 to extrude the second discharge groove 105 on the extrusion plate 95. During the process of the second discharge block 108 extruding the second discharge groove 105, the delay spring 109 will maintain the distance between the first discharge block 104 and the second discharge block 108, preventing the first discharge block 104 from entering the first discharge groove 103 after the second discharge block 108 fails to complete the extrusion of the extrusion plate 95. After the second discharge block 108 completes the extrusion of the second discharge groove 105, the second telescopic plate 107 will slide within the first telescopic plate 106, causing the first discharge block 104 to approach the second discharge block 108. At this time, the first discharge block 104 will extrude the baffle 91 through the first discharge groove 103. When the second discharge block 108 extrudes the second discharge groove 105 on the extrusion plate 95, the inclined surface on one side of the second discharge block 108 will control the movement of the extrusion plate 95 through the second discharge groove 105, causing the extrusion plate 95 to extrude the upper steel strip 5 on its side, thereby fixing the position of the adjacent upper steel strip 5. When the second telescopic plate 107 slides within the first telescopic plate 106 and the delay spring 109 starts to compress, the first discharge block 104 will enter the first discharge groove 103 within the baffle 91 and extrude the baffle 91 through the first discharge groove 103, causing the baffle 91 to release the restriction on the upper steel strip 5 on its side, so that the upper steel strip 5 closest to the opening of the cover plate 88 is detached from the cover plate 88 and sleeved outside the battery pack body 2. When the staff releases the extrusion of the cover plate 88, the first discharge block 104 will first disengage from the first discharge groove 103, and the stop rod 92 provided outside the baffle 91 will be reset under the action of the first control spring 93, causing the stop rod 92 to push the baffle 91 to intercept the previous upper steel strip 5. When the first discharge block 104 completely disengages from the first discharge groove 103 and the delay spring 109 controls the first telescopic plate 106 and the second telescopic plate 107 to reset, the second discharge block 108 will gradually disengage from the second discharge groove 105. At this time, the extrusion rod 97 on one side of the extrusion plate 95 will slide within the second control frame 96 under the action of the second control spring 98, causing the extrusion plate 95 to disengage from the extrusion of the upper steel strip 5, and the upper steel strip 5 that has been disengaged from the extrusion of the extrusion plate 95 will fall above the baffle 91 to prepare for the next sleeving of the upper steel strip 5;

[0058] When the cover plate 88 is pressed down, the rotating rod 811 on one side of the cover plate 88 will squeeze the supporting plate 814 used in conjunction with it, so that the supporting plate 814 moves downward, and the downwardly moving supporting plate 814 will drive the transmission rod 131 at its bottom to move downward, so that the transmission rod 131 slides in the workbench 1, and the downwardly moving transmission rod 131 will pull one end of the transmission rope 132, so that the synchronous plate 123 at the other end of the transmission rope 132 moves upward under the action of the adjusting rod 134, and the adjusting rod 134 can change the lateral force of the transmission rope 132 into an upward force, and the adjusting rod 133 can To prevent the transmission rope 132 from affecting the top plate 121 during the pulling process, when the synchronous plate 123 moves upward under the action of the transmission rope 132, the synchronous plate 123 will drive the multiple top plates 121 on its top to move upward together, and the upwardly moving top plate 121 will push the lower steel bar 4 in the material storage groove 113, so that the lower steel bar 4 in the material storage groove 113 is sleeved on the outside of the battery pack body 2, and the top groove 122 opened on the top plate 121 can be completely fitted with the material storage groove 113, which will not affect the feeding process of the lower steel bar 4. When the synchronous plate 123 is not controlled by external force, the top plate set on the top of the synchronous plate 123 The feeding spring 124 will control the synchronization plate 123 to reset. When the upper steel bar 5 and the lower steel bar 4 are simultaneously sleeved on the outside of the battery pack body 2, the staff can remove the fastened battery pack body 2 through the mechanical arm. When the battery pack body 2 is removed, the feeding plate 114 arranged above the workbench 1 will pop up under the action of the feeding spring 115. The sliding plate arranged at the bottom of the feeding plate 114 can prevent the feeding plate 114 from being bounced up too high by the feeding spring 115. When the feeding plate 114 is bounced up, the U-shaped plate 117 arranged at the bottom of the feeding plate 114 will move upward with the feeding plate 114 and slide When the U-shaped plate 117 moves upward, the end thereof away from the feeding plate 114 will push the lower steel bar 4 in the feeding frame 111 upward, so that the lower steel bar 4 at the bottom will be disengaged from the slot 112 on the feeding frame 111; when the lower steel bar 4 at the bottom is lifted up, the lower steel bar 4 at the bottom will slide toward the feeding plate 114 under the action of gravity; the limiting plate 118 arranged on the workbench 1 can assist in positioning the sliding lower steel bar 4; after the lower steel bar 4 hits the limiting plate 118, the lower steel bar 4 will stay in the storage slot 113 used in conjunction with it, thereby preparing for the next installation.

A third steering pulley 139 is disposed at the bottom of the workbench 1. The transmission rope 136 is wound around the third steering pulley 139, the second steering pulley 138, and the first steering pulley 137 and penetrates through the axis of the auxiliary frame 125 and extends to the top of the synchronous plate 123. When the cover plate 88 is pressed down, the second rotating rod 811 on one side of the cover plate 88 will squeeze the second pallet 814 that is used in cooperation with it, causing the second pallet 814 to move downward. The downward-moving second pallet 814 will drive the transmission rod 135 at its bottom to move downward, causing the transmission rod 135 to slide in the workbench 1. The downward-moving transmission rod 135 will pull one end of the transmission rope 136, causing the synchronous plate 123 at the other end of the transmission rope 136 to move upward under the action of the first steering pulley 137. The first steering rod 133 can change the horizontal force of the transmission rope 136 into an upward force. The second steering pulley 138 can prevent the transmission rope 136 from affecting the top plate 121 during the pulling process. The third steering pulley 139 can prevent the transmission rope 136 from being wound outside the second steering pulley 138 during the downward pulling process. Its function is that the arc surfaces of the first steering pulley 137, the second steering pulley 138, and the third steering pulley 139 can reduce the wear of the transmission rope 136.
