Furthermore, the drawings are not 1: 1, and the relative dimensions of the various elements in the figures are drawn for illustration only and not necessarily to true scale.
Referring to fig. 1, the lamination apparatus 100 according to the preferred embodiment of the present invention includes a frame 110, a lamination mechanism 120, a first feeding mechanism 130, and a second feeding mechanism 140.
Referring to fig. 2, in practical applications, in order to implement batch lamination processing of the battery cells, the lamination apparatus 100 may be provided in plurality to improve lamination efficiency.
Specifically, the plurality of lamination devices 100 form two arrays, and the two arrays are symmetrically arranged. In actual use, an operator only needs to stand outside each queue to realize operation on each lamination device 100, so that each lamination device 100 has a larger operation space, operation of the operator in front of the lamination device 100 is facilitated, and operation of the operator on each lamination device 100 is more convenient.
The frame 110 mainly plays a supporting role. In some embodiments, frame 110 is a large mounting platform on which the various devices and mechanisms of lamination apparatus 100 are mounted.
The lamination mechanism 120 is disposed on the frame 110. The lamination mechanism 120 includes a lamination station 121 and a lamination pendulum roller 122 for folding the diaphragm 20 on the lamination station 121. Wherein the lamination station 121 is a location for lamination to form a cell. Specifically, the lamination table 121 is installed on the frame 110, and the lamination swing roller 122 is disposed on a side of the lamination table 121 away from the frame 110. When the lamination apparatus 100 is positioned in the horizontal plane, the lamination swing roller 122 is positioned directly above the lamination table 121.
Referring also to fig. 3, the lamination stage 121 has a first position 1211 and a second position 1212 spaced apart from each other. The lamination pendulum roller 122 is reciprocally movable between a first position 1211 and a second position 1212 to fold the membrane 20 on the lamination table 121 to form a Z-shaped lamination. Therefore, the connection direction between the first position 1211 and the second position 1212 is consistent with the translation direction of the lamination swing roller 122, and is parallel to the blanking direction of the battery cell formed after lamination on the lamination table 121. When the laminating apparatus 100 is located in a horizontal plane, a line connecting the first position 1211 and the second position 1212 is in a horizontal direction.
Specifically, the lamination mechanism 120 further includes a lift drive assembly 123. Two ends of the lifting driving assembly 123 are respectively connected with the lamination table 121 and the frame 110, and are used for driving the lamination table 121 to lift. Therefore, in the lamination process, along with the increase of the thickness of the lamination, the lifting driving assembly 123 drives the lamination table 121 to gradually descend so as to ensure the realization of the lamination function and the improvement of the lamination effect; after the battery cell after lamination is completed is taken away, the lifting driving assembly 123 drives the lamination table 121 to ascend, so as to reset the lamination table 121.
Referring to fig. 4, in more detail, a first pressing block 124 and a second pressing block 125 are disposed on a side of the lamination table 121 away from the frame 110. The first pressing block 124 and the second pressing block 125 are respectively located at a first position 1211 and a second position 1212. Specifically, the lamination oscillating roller 122 drives the diaphragm 20 to reciprocate between the first position 1211 and the second position 1212, so that the diaphragm 20 respectively bypasses the first pressing block 124 and the second pressing block 125, and the diaphragm 20 is folded on the lamination table 121 to form the Z-shaped lamination.
Referring again to fig. 3, in particular, the lamination apparatus 100 further includes a horizontal movement driving member 126. The horizontal movement driving member 126 is drivingly connected to the lamination oscillating roller 122 and is used for driving the lamination oscillating roller 122 to reciprocate along a line connecting the first position 1211 and the second position 1212. Thus, the horizontal movement drive 126 may enable automated operation of the lamination pendulum roller 122 to ensure lamination accuracy.
Referring again to fig. 1, in some embodiments, the lamination apparatus 100 further includes a membrane unwinding mechanism 150. The membrane unwinding mechanism 150 is disposed on the frame 110 and is used for releasing the membrane 20 from the roll. The lamination pendulum roller 122 is used for folding the diaphragm 20 released by the diaphragm unwinding mechanism 150 on the lamination table 121 to form a Z-shaped lamination. Therefore, the membrane unwinding mechanism 150 can realize the automatic release of the membrane 20, so as to improve the lamination precision and ensure the lamination effect of the lamination device 100.
The first feeding mechanism 130 is disposed on the frame 110 and spaced apart from the lamination mechanism 120. The first feeding mechanism 130 is used for conveying the first pole piece to the lamination table 121. The second feeding mechanism 140 is disposed on the frame 110 and spaced apart from the lamination mechanism 120. The second feeding mechanism 140 is used for conveying the second pole 40 to the lamination stage 121. The first pole piece 30 is one of the positive and negative pole pieces of the lithium battery, and the second pole piece 40 is the other of the positive and negative pole pieces of the lithium battery.
Before and during the operation of the lamination device 100, the first pole piece 30 and the second pole piece 40 may be respectively transported to the first feeding mechanism 130 and the second feeding mechanism 140 by mechanical transportation, manual transportation, and the like.
The process of processing the cell lamination by using the lamination apparatus 100 is as follows: the lamination pendulum roller 122 drives the membrane 20 to move from the second position 1212 to the first position 1211, so as to lay a layer of the membrane 20 on the lamination table 121; when the lamination pendulum roller 122 moves to the first position 1211, the second feeding mechanism 140 transfers and stacks the second pole piece 40 onto the folded diaphragm 20 on the lamination station 121; then, the lamination pendulum roller 122 drives the diaphragm 20 to move from the first position 1211 to the second position 1212, so as to coat the second pole piece 40 with the diaphragm 20; when the lamination pendulum roller 122 reaches the second position 1212, the first feeding mechanism 130 transports and stacks the first pole piece 30 onto the folded diaphragm 20 of the lamination station 121; then, the lamination swing roller 122 is used to drive the diaphragm 20 to move from the second position 1212 to the first position 1211, so as to realize the coating of the first pole piece 30 by the diaphragm 20; the above steps are repeated continuously so that the folded separator 20, the first pole piece 30 and the second pole piece 40 form a cell on the lamination station 121.
Wherein the first feeding mechanism 130 is located on the upstream side of the lamination stage 121. The connecting direction of the second feeding mechanism 140 and the lamination table 121 forms an included angle with the translation direction of the lamination swinging roller 122.
The lamination table 121 has an upstream side and a downstream side, wherein the downstream side is a side of the lamination table 121 for blanking, and the upstream side is a side of the lamination table 121 far from the downstream side in the translation direction of the lamination swing roller 122. The translation direction of the lamination swing roller 122 is parallel to the blanking direction of the battery cell formed after lamination on the lamination table 121, so that the blanking position of the battery cell on the lamination table 121 is located on the downstream side of the lamination table 121.
Since the first feeding mechanism 130 and the lamination mechanism 120 are arranged at intervals and located on the upstream side of the lamination table 121, the first feeding mechanism 130 does not interfere with the blanking position located on the downstream side of the lamination table 121; since the second feeding mechanism 140 and the lamination mechanism 120 are arranged at an interval, and the connecting direction of the second feeding mechanism 140 and the lamination table 121 and the translation direction of the lamination swing roller 122 form an included angle, the connecting direction of the second feeding mechanism 140 and the lamination table 121 and the blanking direction of the battery cell form an included angle, and therefore, even if the second feeding mechanism 140 is arranged at the downstream side of the lamination table 121, the second feeding mechanism 140 does not interfere with the blanking position of the lamination table 121. Specifically, the direction of the second pole piece 40 moving from the second feeding mechanism 140 to the lamination table 121 and the translation direction of the lamination swing roller 122 form an included angle.
Compared with the lamination mode in the prior art, the lamination device 100 can directly perform blanking of the battery cells at the blanking position of the lamination table 121 without repeatedly moving (e.g., moving up and down) the first feeding mechanism 130 and/or the second feeding mechanism 140 or other components, so that lamination auxiliary time required by repeatedly moving the first feeding mechanism 130 and/or the second feeding mechanism 140 is saved, and lamination efficiency is effectively improved.
In some embodiments, the second feed mechanism 140 is located on the frame 110 near the downstream side of the lamination station 121. The included angle between the connecting direction of the second feeding mechanism 140 and the lamination table 121 and the translation direction of the lamination swinging roller 122 is in the range of 30 degrees to 90 degrees. Thus, the second feeding mechanism 140 may never be located on the upstream side of the lamination stage 122, nor at the blanking position of the lamination stage 122. During the lamination process, when the lamination oscillating roller 122 drives the diaphragm 20 to move to the first position 1211, the second feeding mechanism 140 may feed the second pole piece 40 onto the lamination table 121; when the lamination oscillating roller 121 drives the diaphragm 20 to move to the second position 1212, the first feeding mechanism 130 can convey the first pole piece 30 onto the lamination table 121.
Therefore, the second feeding mechanism 140 is arranged at the downstream side of the lamination table 121, and the included angle range between the connecting line direction of the second feeding mechanism 140 and the lamination table 121 and the translation direction of the lamination swinging roller 122 is set to be 30-90 degrees, so that the probability of interference with the diaphragm and/or the lamination swinging roller in the process of conveying the second pole piece 40 to the lamination table 121 is low, and the reliability of the lamination device 100 in lamination is effectively improved.
Further, in the prior art, in order to reduce the interference between the second feeding mechanism 140 and the blanking position of the lamination table 121 and the diaphragm, the second feeding mechanism 140 needs to be moved upward or downward until the second feeding mechanism 140 is abutted to the lamination table 121, and then the feeding to the lamination table 121 is not realized. The second feeding mechanism 140 is arranged at the downstream side of the lamination table 121, and the included angle range between the connecting line direction of the second feeding mechanism 140 and the lamination table 121 and the translation direction of the lamination swinging roller 122 is set to be 30 degrees to 90 degrees, so that the lamination device 100 can directly utilize the second feeding mechanism 140 to realize feeding to the lamination table 121 without moving the second feeding mechanism 140 upwards or downwards, the time for moving the second feeding mechanism 140 to realize butt joint with the lamination table 121 is saved, and the lamination efficiency is further improved.
Referring again to fig. 1, in some embodiments, the first feeding mechanism 130 includes a first feeding assembly 131 and a first transferring assembly 132. The first feeding assembly 131 is used for feeding the first pole piece 30. The first transfer assembly 132 is used for transferring the first pole piece 30. Specifically, the first transfer assembly 132 is located between the first feeding assembly 131 and the lamination mechanism 120.
The second feeding mechanism 140 includes a second feeding assembly 141 and a second transferring assembly 142. The second feeding assembly 141 is used for feeding the second pole piece 40. The second transfer assembly 142 is used for transferring the second pole piece 40. Specifically, the second transferring assembly 142 is located between the second feeding assembly 141 and the lamination mechanism 120.
The first transfer module 132 and the second transfer module 142 may be robots, transfer robots, vacuum suction modules, and the like.
In practical application, an operator carries the first pole piece 30 and the second pole piece 40 to the first feeding assembly 131 and the second feeding assembly 131 respectively through mechanical transfer, manual transfer and the like; during the lamination process, the first transfer assembly 132 transfers the first pole piece 30 on the first feeding assembly 131 to the lamination table 121; the second transfer assembly 142 transfers the second pole piece 40 on the second feeding assembly 141 to the lamination table 121, so as to realize the lamination function of the lamination device 100 on the lamination table 121. Therefore, the first feeding mechanism 130 is provided as the first feeding assembly 131 and the first transferring assembly 132, and the second feeding mechanism 140 is provided as the second feeding assembly 141 and the second transferring assembly 142, so as to facilitate the circulation of the first pole piece 30 and the second pole piece 40 between the mechanisms on the lamination device 100, and make the lamination device 100 simpler in structure and make the circulation of the first pole piece 30 and the second pole piece 40 on the lamination device 100 simpler.
Referring to fig. 2 again, in some embodiments, the first loading assembly 131 includes a first supporting frame 1311 and a first transferring unit 1312. The first support frame 1311 has a first station 1313, a second station 1314 and a third station 1315 arranged at intervals. In an actual application process, the first station 1313 is a feeding station for the first pole piece 30, the second station 1314 is a station for the second transfer component 142 to transfer the first pole piece 30 (that is, the second transfer component 142 is used to transfer the first pole piece 30 on the second station 1314), and the third station 1315 is a discharging station. The first transmission member 1312 is slidably installed on the first support frame 1311 and is used for enabling the first battery pole piece magazine 50 to sequentially pass through the first station 1313, the second station 1314 and the third station 1315. The first battery pole piece magazine 50 is a storage box for containing the first pole piece 30. Specifically, the first transfer assembly 132 is used to transfer the first pole piece 30 in the first battery pole piece magazine 50 at the second station 1314. Specifically, the first transfer member 1312 is intermittently slidable relative to the first support frame 1311 to facilitate transfer of the first pole piece 30 at the second station 1314.
In practical application, an operator transports the first battery pole piece magazine 50 with the first pole piece 30 to a position where the first transmission member 1312 is opposite to the first station 1313, starts the first transmission member 1312 to slide to drive the first battery pole piece magazine 50 to the second station 1314, at this time, the first transfer member 132 can sequentially transport the first pole piece 30 in the first battery pole piece magazine 50 to the first deviation-rectifying positioning platform, after the transport of the first pole piece 30 in the first battery pole piece magazine 50 is completed, the first transmission member 1312 continues to slide to drive the first battery pole piece magazine 50 to the third station 1315, and the operator takes the first battery pole piece magazine 50 off from the third station 1315. When the battery pole piece feeding device is used, an operator can directly pick and place the first battery pole piece box 50 from the third station 1315 and the first station 1313 which are far away from the second transfer assembly 142, so that the probability of the situation that the operator touches the first transfer assembly 132 to cause injury and the like when the operator picks and places the first battery pole piece box 50 is reduced.
If the operator chooses to take and put the first battery pole piece material box 50 after the shutdown for safety, the lamination efficiency will be affected. The first feeding assembly 131 is provided as the first supporting frame 1311 and the first conveying member 1312, and the operation of taking and placing the first pole piece 30 on the first conveying member 1312 can be realized without stopping the machine (that is, the first pole piece 20 can be conveyed onto the first conveying member 1312 without stopping the machine, and the first conveying assembly 132 can also be used for transferring the first pole piece 30 from the first conveying member 1312 to the lamination table 121), so that the lamination efficiency of the lamination apparatus 100 is further improved while the use safety is ensured.
It is understood that in other embodiments, the first transfer member 1312 is used for placing the first pole piece 30, and the first pole piece 30 passes through the first station 1313 and the second station 1314 in sequence during the driving of the first transfer member 1312. At this time, the first transmission element 1312 may drive the first pole piece 30 to intermittently move, or may drive the first pole piece 30 to continuously slide.
The second feeding assembly 141 includes a second supporting frame 1411 and a second conveying member 1412. The second support frame 1411 has a fourth station 1413, a fifth station 1414 and a sixth station 1415 which are arranged at intervals. In practical applications, the fourth station 1413 is a feeding station for the second pole piece 40, the fifth station 1414 is a station for transferring the second pole piece 40 by the second transfer assembly 142 (that is, the second transfer assembly 142 is used for transferring the second pole piece on the fifth station 1414), and the sixth station 1415 is a discharging station.
The second conveying member 1412 is slidably mounted on the second support frame 1411 and is used for enabling the second battery pole piece magazine 60 to sequentially pass through the fourth station 1413, the fifth station 1414 and the sixth station 1415. The second battery pole piece magazine 60 is a storage box for containing the second pole piece 40. The second transfer assembly 142 is used to transfer the second pole piece 40 in the second battery pole piece magazine 60 at the fifth station 1414. Specifically, the second transfer member 1412 may intermittently slide relative to the second support bracket 1411.
It should be noted that, the functions and structures of the second feeding assembly 141 and the second feeding assembly 131 are the same, and only the differences of the objects of action exist (the first feeding assembly 131 acts on the first pole piece 30, and the second feeding assembly 141 acts on the second pole piece 40), so the working processes and beneficial effects of the second feeding assembly 141 and the first feeding assembly 131 are similar, and are not described herein again.
Specifically, the first conveying member 1312 and the second conveying member 1412 may be conveyor belts, conveyor chains, or the like.
Further, in some embodiments, lamination apparatus 100 further includes two de-skew positioning mechanisms disposed on frame 110. One of the deviation-correcting positioning mechanisms is located between the first feeding assembly 131 and the lamination mechanism 120, and the other deviation-correcting positioning mechanism is located between the second feeding assembly 141 and the lamination mechanism 120.
Each deviation rectifying and positioning mechanism comprises a deviation rectifying and positioning platform. The first transfer assembly 132 is used for transferring the first pole piece 30 on the first feeding assembly 131 to the corresponding deviation rectifying and positioning platform and transferring the first pole piece 30 on the deviation rectifying and positioning platform to the lamination table 121. The second transfer assembly 142 is used for transferring the second pole piece 40 on the second feeding assembly 141 to the corresponding deviation-rectifying positioning platform and transferring the second pole piece 40 on the deviation-rectifying positioning platform to the lamination table 121.
Each deviation rectifying and positioning platform is used for driving the corresponding first pole piece 30 and the second pole piece 40 to rotate around the central axis of the deviation rectifying and positioning platform where the first pole piece 30 and the second pole piece 40 are located, and/or move in the plane perpendicular to the central axis, so as to adjust the placing positions of the first pole piece 30 and the second pole piece 40.
For simplicity, the two deskewing positioning mechanisms are respectively positioned as a first deskewing positioning mechanism 160 and a second deskewing positioning mechanism 170.
The first deviation-rectifying positioning mechanism 160 is located between the first feeding assembly 131 and the lamination mechanism 120. The first deviation rectifying and positioning mechanism 160 includes a first deviation rectifying and positioning platform (not shown). The first transfer assembly 132 is used for transferring the first pole piece 30 to the first deviation rectifying and positioning platform. The first deviation rectifying and positioning platform is controlled to drive the first pole piece 30 to rotate around the central axis of the first deviation rectifying and positioning platform and/or move in a plane perpendicular to the central axis so as to adjust the placement position of the first pole piece 30.
When the lamination device 100 is located on the horizontal plane, the central axis of the first deviation rectifying and positioning platform is a vertical line, and the plane perpendicular to the central axis is a horizontal plane. Therefore, in the practical application process, the first deviation rectifying and positioning platform rotates around the vertical line and/or moves in the horizontal plane to adjust the placing position of the first pole piece 30, so that when the first pole piece 30 is transferred to the lamination table 121, the first pole piece 30 has a better stacking position on the lamination table 121, the lamination effect of the lamination device 100 is improved, and the product quality is guaranteed.
The second deviation-rectifying positioning mechanism 170 is located between the second feeding assembly 141 and the lamination mechanism 120. The second deviation rectifying and positioning mechanism 170 includes a second deviation rectifying and positioning platform (not shown). The second transfer assembly 142 is used for transferring the second pole piece 40 to the second deviation rectifying and positioning platform. The second deviation rectifying and positioning platform is controlled to drive the second pole piece 40 to rotate around the central axis of the second deviation rectifying and positioning platform and/or move in the plane vertical to the central axis so as to adjust the placing position of the second pole piece 40.
When the lamination device 100 is located on the horizontal plane, the central axis of the second deviation-rectifying positioning platform is a vertical line, and the plane perpendicular to the central axis is a horizontal plane. In the practical application process, the second deviation-rectifying positioning platform and the first deviation-rectifying positioning platform have the same function and structure, and only the difference of the acting objects exists (the first deviation-rectifying positioning platform acts on the first pole piece 30, and the second deviation-rectifying positioning platform acts on the second pole piece 40), so the working process and the beneficial effect of the second deviation-rectifying positioning mechanism 170 and the first deviation-rectifying positioning mechanism 160 are similar, and the description is omitted here.
Referring also to fig. 5, in some embodiments, the first transfer unit 132 includes a first support 1321 and two first suction fittings 1322 mounted on the first support 1321. The two first suction fittings 1322 are arranged at intervals along the connecting line direction of the first feeding assembly 131 and the lamination table 121, and can synchronously move along the connecting line direction of the first feeding assembly 131 and the lamination table 121, so as to synchronously transfer the first pole piece 30 on the first feeding assembly 131 to the corresponding deviation rectifying and positioning platform and the first pole piece 30 on the deviation rectifying and positioning platform to the lamination table 121 respectively. When the two deviation-rectifying positioning mechanisms are defined as the first deviation-rectifying positioning mechanism 160 and the second deviation-rectifying positioning mechanism, the two first suction pieces 1322 move synchronously to respectively suck the first pole piece 30 on the first feeding assembly 131 to the first deviation-rectifying positioning platform and suck the first pole piece 30 on the first deviation-rectifying positioning platform to the lamination table 121 at the same time.
Specifically, the distance between the first feeding assembly 131 and the first deviation rectifying and positioning platform is the same as the distance between the first deviation rectifying and positioning platform and the lamination table 121. The first suction device 1322 sucks the first pole piece 30. And the first suction member 1322 may be a vacuum suction member, an electromagnetic suction member, or the like. Specifically, in this embodiment, the first suction device 1322 is a vacuum suction device. Under the effect of the two first suction fittings 1322, the transferring action of the first pole piece 30 on the first feeding assembly 131 to the first deviation-rectifying positioning mechanism 160 and the transferring action of the first pole piece 30 on the first deviation-rectifying positioning platform to the lamination table 121 are performed simultaneously, and compared with a separate transferring mode, the synchronous transferring mode greatly improves the transferring speed of the first pole piece 30 among the mechanisms of the lamination device 100, and further improves the lamination efficiency of the lamination device 100.
Specifically, the first transfer assembly 132 further includes a first link 1323. The two first suction pieces 1322 are disposed at intervals along a line connecting the first feeding assembly 131 and the lamination stage 121 on the first link 1323. The first link 1323 is slidably mounted on the first support 1321 in a direction of connecting the first feeding member 131 and the lamination stage 121. Specifically, the distance between the first feeding assembly 131 and the first deviation rectifying and positioning platform is the same as the distance between the first deviation rectifying and positioning platform and the lamination table 121, and is equal to the distance between the two first suction fittings 1322. In practical applications, the first link 1323 slides along a connecting line of the first feeding assembly 131 and the lamination table 121 to drive the two first suction fittings 1322 to reciprocate along the connecting line of the first feeding assembly 131 and the lamination table 121, so that the first link 1323 is used for driving the two first suction fittings 1322 to move synchronously.
Referring to fig. 6, the second transfer assembly 142 includes a second support 1421 and two second adsorption elements 1422 mounted on the second support 1421. The two second adsorption parts 1422 are disposed at intervals along the connection line direction of the second feeding assembly 141 and the lamination table 121, and can move synchronously along the connection line direction of the second feeding assembly 141 and the lamination table 121, so as to respectively transfer the second pole piece 40 on the second feeding assembly 142 to the corresponding deviation-rectifying positioning platform and transfer the second pole piece 40 on the deviation-rectifying positioning platform to the lamination table 121 synchronously.
When the two deviation-correcting positioning mechanisms are defined as the first deviation-correcting positioning mechanism 160 and the second deviation-correcting positioning mechanism 170, the two second adsorbing members 1422 move synchronously to adsorb the second pole piece 40 on the second feeding assembly 141 to the second deviation-correcting positioning platform and adsorb the second pole piece 40 on the second deviation-correcting positioning platform to the lamination table 121, respectively.
Specifically, the distance between the second feeding assembly 141 and the second deviation-rectifying positioning platform is the same as the distance between the second deviation-rectifying positioning platform and the lamination table 121. The second suction member 1422 is used to suck the second pole piece 40. And the second adsorbing member 1422 may be a vacuum adsorbing member, an electromagnetic adsorbing member, or the like. Specifically, in this embodiment, the second suction member 1422 is a vacuum suction member. Under the action of the two second adsorption parts 1422, the transferring action of the second pole piece 40 on the second feeding assembly 141 to the second deviation-rectifying positioning platform and the transferring action of the second pole piece 40 on the second deviation-rectifying positioning platform to the lamination table 121 are performed simultaneously, and compared with a single and step-by-step transferring mode, the synchronous transferring mode greatly improves the speed of the second pole piece 40 transferring among the mechanisms of the lamination equipment 100, and further improves the lamination efficiency of the lamination equipment 100.
Specifically, the second transfer assembly 142 further includes a second link 1423. The two second suction members 1422 are disposed at intervals on the second connecting rod 1423 along a connecting line of the second feeding assembly 141 and the lamination table 121. The second connecting rod 1423 is slidably mounted on the second support 1421 along a line connecting the second feeding assembly 141 and the lamination table 121. Specifically, the distance between the second feeding assembly 141 and the second deviation-rectifying positioning platform is the same as the distance between the second deviation-rectifying positioning platform and the lamination table 121, and is equal to the distance between the two second adsorption pieces 1422. In practical applications, the second connecting rod 1423 slides along the connecting line of the second feeding assembly 141 and the lamination table 121 to drive the two second absorption members 1422 to reciprocate along the connecting line of the second feeding assembly 141 and the lamination table 121, so that the second connecting rod 1423 is used for driving the two second absorption members 1422 to move synchronously.
Further, in some embodiments, lamination apparatus 100 further comprises a controller (not shown) and two detection mechanisms (not shown). One of the detecting mechanisms is used for detecting the position information and/or defect information of the first pole piece 30 on the corresponding deviation rectifying and positioning platform, and the other detecting mechanism is used for detecting the position information and/or defect information of the second pole piece 40 on the corresponding deviation rectifying and positioning platform.
The controller is electrically connected with each detection mechanism and is used for controlling the corresponding deviation rectifying and positioning platform to drive the first pole piece 30 and the second pole piece 40 to rotate around the central axis of the deviation rectifying and positioning platform where the first pole piece 30 and the second pole piece 40 are located according to the position information of the first pole piece 30 and the position information of the second pole piece 40 respectively, and the controller moves in a plane perpendicular to the central axis to adjust the placing positions of the first pole piece 30 and the second pole piece 40.
The controller is electrically connected with the first feeding mechanism 130 and is used for controlling the first feeding mechanism 130 to transfer the first pole piece 30 on the corresponding deviation rectifying and positioning platform according to the position information and/or the defect information of the first pole piece 30. The controller is electrically connected with the second feeding mechanism 140 and is used for controlling the second feeding mechanism 140 to transfer the second pole piece 40 on the corresponding deviation rectifying and positioning platform according to the position information and/or the defect information of the second pole piece 40.
Specifically, the controller is electrically connected to the first transfer assembly 132 and is configured to control the first transfer assembly 131 to transfer the first pole piece 30 on the corresponding deviation rectifying and positioning platform according to the position information and/or the defect information of the first pole piece 30; the controller is electrically connected with the second transfer assembly 142 and is used for controlling the second transfer assembly 142 to transfer the second pole piece 40 on the corresponding deviation rectifying and positioning platform according to the position information and/or the defect information of the second pole piece 40.
For simplicity, the two detection mechanisms are defined as a first detection mechanism and a second detection mechanism, respectively.
The first detection mechanism is used for detecting the position information and/or the defect information of the first pole piece 30 on the first deviation rectifying and positioning platform, and the second detection mechanism is used for detecting the position information and/or the defect information of the second pole piece 40 on the second deviation rectifying and positioning platform. Specifically, the first detecting mechanism is disposed on the first deviation-rectifying positioning mechanism 160, and the second detecting mechanism is disposed on the second deviation-rectifying positioning mechanism 170.
The first detection mechanism detects the position information of the first pole piece 30, which means that whether the placing position of the first pole piece 30 on the first deviation rectifying and positioning platform is matched with a preset placing position is detected, and the first detection mechanism detects the defect information of the first pole piece 30, which means that whether the first pole piece 30 has defects such as damage, size unqualified and the like is detected; the second detection mechanism detects the position information of the second pole piece 40, which means that whether the placing position of the second pole piece 40 on the second deviation rectifying and positioning platform is matched with the preset placing position is detected, and the second detection mechanism detects the defect information of the second pole piece 40, which means that whether the second pole piece 40 has defects such as damage, unsatisfactory size and the like is detected.
The controller is electrically connected to the first deviation-rectifying positioning mechanism 160, and is used for controlling the first deviation-rectifying positioning platform to rotate around the central axis of the first deviation-rectifying positioning platform according to the position information of the first pole piece 30, and to move in the plane perpendicular to the central axis, so as to adjust the placement position of the first pole piece 30. The controller is electrically connected to the first transfer assembly 132 and is used for controlling the first transfer assembly 132 to transfer the first pole piece 30 on the first deviation rectifying and positioning platform according to the position information and the defect information of the first pole piece 30.
Specifically, the controller firstly judges whether the first pole piece 30 has defects such as damage, unsatisfactory size and the like according to the defect information of the first pole piece 30 collected by the first detection mechanism, and if the first pole piece 30 has defects, the controller controls the first transfer assembly 132 to transfer the first pole piece 30 to the unqualified product collection area; if the first pole piece 30 has no defect, the controller further judges whether the placing position of the first pole piece 30 on the first deviation-rectifying positioning platform is matched with the preset placing position, if not, the controller controls the first deviation-rectifying positioning platform to drive the first pole piece 30 to rotate and/or move in a plane perpendicular to the central axis according to the difference between the placing position of the first pole piece 30 and the preset placing position until the placing position of the first pole piece 30 is matched with the first preset position; if the two pole pieces are matched, the controller controls the first transfer assembly 132 to transfer the first pole piece 30 to the lamination table 121 for lamination.
The controller is electrically connected to the second deviation-rectifying positioning mechanism 170, and is configured to control the second deviation-rectifying positioning platform to rotate around the central axis of the second deviation-rectifying positioning platform according to the position information of the second pole piece 40, and move in the plane perpendicular to the central axis, so as to adjust the placement position of the second pole piece 40. The controller is electrically connected to the second transfer assembly 142 and is used for controlling the second transfer assembly 142 to transfer the second pole piece 40 on the second deviation rectifying and positioning platform according to the position information and the defect information of the second pole piece 40.
Specifically, the controller firstly judges whether the second pole piece 40 has defects such as damage, unsatisfactory size and the like according to the defect information of the second pole piece 40 collected by the second detection mechanism, and if the second pole piece 40 has defects, the controller controls the second transfer assembly 142 to transfer the second pole piece 40 to the unqualified product collection area; if the second pole piece 40 has no defect, the controller further judges whether the placing position of the second pole piece 40 on the second deviation-rectifying positioning platform is matched with the preset placing position, if not, the controller controls the second deviation-rectifying positioning platform to drive the second pole piece 40 to rotate around the central axis of the second deviation-rectifying positioning platform and/or move in a plane perpendicular to the central axis according to the difference between the placing position of the second pole piece 40 and the preset placing position until the placing position of the second pole piece 40 is matched with the preset placing position; if the two pole pieces are matched, the controller controls the second transfer assembly 142 to transfer the second pole piece 40 to the lamination table 121 for lamination.
Therefore, the controller can realize the automatic control of the first detection mechanism, the first feeding mechanism 130, the second detection mechanism, the second feeding mechanism 140 and the like, and realize the transferring precision of the first pole piece 30 and the second pole piece 40, thereby improving the precision of the lamination. Moreover, the controller is respectively matched with the first detection mechanism and the second detection mechanism, so that the first pole piece 30 and the second pole piece 40 with defects can be prevented from being used in the lamination process, and the reliability of the product is improved.
Referring again to fig. 1, in some embodiments, the lamination equipment 100 further includes a first reject collector 220 disposed on the frame 110 and a second reject collector 230 disposed on the frame 110.
The controller is electrically connected to the first unqualified collecting device 220 and is used for controlling the first unqualified collecting device 220 to move the first collecting box to a position close to the first deviation rectifying and positioning platform according to the defect information of the first pole piece 30, so as to collect the first pole piece 30 with a defect on the first deviation rectifying and positioning platform. Wherein, the first collecting box is mainly used for collecting and storing the first pole piece 30 with defects. When the first pole piece 30 on the first deviation-rectifying positioning mechanism 160 is detected to have a defect, the controller controls the first unqualified collecting device 220 to move the first collecting box (not shown) to a position close to the first deviation-rectifying positioning platform, so that the first transporting assembly 132 can transport the unqualified first pole piece 30 into the first collecting box, and the use of the lamination device 100 is convenient due to the arrangement of the first unqualified collecting device 220.
Specifically, the controller controls the first unqualified collection device 220 to move the first collection box to the side of the first deviation rectification positioning platform away from the rack 110 according to the defect information of the first pole piece 30. When the lamination device 100 is located on the horizontal plane, the controller controls to move the first collecting box to the position above the first deviation-rectifying positioning platform according to the defect information of the first pole piece 30, so that the operation of transferring the first pole piece 30 with the defect on the first deviation-rectifying positioning platform into the first collecting box by the first transferring assembly 142 is more convenient, and the use of the lamination device 100 is further more convenient.
The controller is electrically connected to the second unqualified collection device 230 and is used for controlling the second unqualified collection device 230 to move the first collection box (not shown) to a position close to the second de-skew positioning platform according to the defect information of the second pole piece 40, so as to collect the second pole piece 40 with the defect on the second de-skew positioning platform. Wherein, the second collecting box is mainly used for collecting and storing the second pole piece 40 with defects. When the second pole piece 40 on the second deviation-rectifying positioning mechanism 170 is detected to have a defect, the controller controls the second unqualified collecting device 230 to move the second collecting box to a position close to the second deviation-rectifying positioning platform, so that the second transfer assembly 142 can transfer the unqualified second pole piece 40 into the second collecting box, and the second unqualified collecting device 230 is arranged, so that the lamination device 100 is convenient to use.
Specifically, the controller controls the second unqualified collection device 230 to move the second collection box to the side of the second deviation rectification positioning platform away from the rack 110 according to the defect information of the second pole piece 40. When the lamination device 100 is located on the horizontal plane, the controller controls to move the second collecting box to the position above the second deviation-rectifying positioning platform according to the defect information of the second pole piece 40, so that the operation of transferring the defective second pole piece 40 on the second deviation-rectifying positioning platform into the second collecting box by the second feeding mechanism 140 is more convenient, and the use of the lamination device 100 is further more convenient.
It should be noted that the controller may be electrically connected to the first feeding mechanism 130, the second feeding mechanism 140, the first deviation-correcting positioning mechanism 160, the second deviation-correcting positioning mechanism 170, the lamination mechanism 120, the first detection mechanism, and the second detection mechanism at the same time, so as to implement automatic control of the above mechanisms, and thus, the lamination device 100 can be fully automated. The controller may be electrically connected to only some of the above mechanisms, so that some mechanisms are controlled automatically, and other mechanisms are controlled manually, so as to achieve semi-automation of the lamination device 100.
Referring also to fig. 7, in some embodiments, the lamination apparatus 100 further includes a blanking mechanism 180 disposed on the frame 110. The blanking mechanism 180 is located on the downstream side of the lamination mechanism 120. The blanking mechanism 180 is used for transferring out the battery cores formed after lamination on the lamination table 121. Specifically, the connection line between the blanking mechanism 180 and the stacking mechanism 120 is the same as the connection line between the first position 1211 and the second position 1212.
Blanking mechanism 180 includes a cell clamping device 181. The cell clamping device 181 is used for grabbing and transferring the cells formed after lamination on the lamination table 121. Thus, after the lamination apparatus 100 performs lamination and forms a cell on the lamination station 121, the cell clamping device 181 immediately moves to a position close to the lamination station 121, and grasps the cell on the lamination station 121 and brings the cell away from the lamination station 121. Therefore, due to the arrangement of the battery cell clamping device 181, the blanking of the battery cells formed on the lamination table 121 is more convenient.
Referring to fig. 8, further, in some embodiments, the blanking mechanism 180 further includes a film clamping device 182. The film clamping device 182 is used for clamping the diaphragm 20 between the lamination mechanism 120 and the cell clamping device 181. The lamination apparatus 100 also includes a cutter mechanism 190. The cutter mechanism 190 is disposed on the frame 110 and is used to cut the diaphragm 20 clamped by the film clamping device 182. Specifically, the cutter mechanism 190 is located between the laminating table 121 and the film clamping device 182.
After the cell clamping device 181 clamps and takes the cell on the lamination table 121 away from the lamination table 121 by a distance, the diaphragm 20 between the cell and the lamination swing roller 122 is clamped and stretched by the film clamping device 182; at this time, the cutter mechanism 190 moves to a corresponding position, and performs a cutting operation on the clamped diaphragm 20 to cut the diaphragm 20. Therefore, the film clamping device 182 and the cutter mechanism 190 effectively improve the cutting precision and effect of the diaphragm 20, and greatly improve the quality of the battery core.
Referring again to fig. 2 and 7, further, in some embodiments, the blanking mechanism 180 further includes a guide 183 extending along the translation direction of the lamination pendulum roller 122. The cell clamping device 181 and the film clamping device 182 are slidably mounted on the guide 183. Thus, the guide 183 is provided to improve the operation accuracy of the cell clamping device and the film clamping device 182.
Referring again to fig. 1, further, in some embodiments, the lamination apparatus 100 further includes a tail-wind mechanism 210. The tail-wind mechanism 210 is disposed at the frame 110. The tail winding mechanism 210 is used for winding the tail of the cut diaphragm 20 to the outer surface of the battery core. Therefore, the tail winding mechanism 210 can wind the tail part of the cut diaphragm 20 to the surface of the battery core, and the winding effect of the cut diaphragm 20 on the battery core is better, so that the quality of the formed battery core is ensured. And the tail winding mechanism 210 can also improve the efficiency of winding the tail of the cut diaphragm 20, and further improve the lamination efficiency of the lamination device 100.
Further, in some embodiments, the lamination apparatus 100 further includes a taping mechanism (not shown). The adhesive applying mechanism is disposed on the frame 110 and is used for adhering the cut diaphragm 20 to the surface of the battery cell. The cut diaphragm 20 is bonded to the first pole piece 30 or the second pole piece 40, so that the battery cell formed after lamination is prevented from scattering in the subsequent transferring, operating and other processes, and the stability of the battery cell structure is improved. And the arrangement of the rubberizing mechanism can ensure the bonding effect of the diaphragm 20 and the first pole piece 30 or the second pole piece 40.
In the lamination apparatus 100, the translation direction of the lamination pendulum roller 122 is parallel to the blanking direction of the battery core formed after lamination. Because the second feeding mechanism 140 and the lamination mechanism 120 are arranged at intervals, and the connecting direction of the second feeding mechanism 140 and the lamination table 121 and the translation direction of the lamination swing roller 122 form an included angle, the conveying direction of the second pole piece 40 and the translation direction of the lamination swing roller 122 form an included angle, and the second feeding mechanism 140 cannot interfere with the blanking position of the lamination table 121 even if arranged at the downstream side of the lamination table 121; since the first feeding mechanism 130 is disposed at a distance from the lamination mechanism 120 and on the upstream side of the lamination stage 121, the first feeding mechanism 130 does not interfere with the blanking position on the downstream side of the lamination stage 121.
Compared with the lamination mode in the prior art, the lamination device 100 can directly perform the blanking operation of the battery cell at the blanking position of the lamination table 121 without repeatedly moving (for example, moving up and down) the first feeding mechanism 130 and/or the second feeding mechanism 140, so that the lamination auxiliary time required by repeatedly moving the first feeding mechanism 130 and/or the second feeding mechanism 140 is saved, and the lamination efficiency is effectively improved; further, the lamination apparatus 100 may perform the feeding operation of the first pole piece 30 or the second pole piece 40 to the lamination table 121 while cutting the diaphragm 20, and it is not necessary to perform the feeding operation of the first pole piece 30 or the second pole piece 40 to the lamination table 121 after the diaphragm 20 is completely cut and the blanking mechanism 180 is moved to perform the cell blanking as in the prior art, so that the lamination efficiency is further improved.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
