Description

Technical Field

[0001] The present application relates to the technical field of battery cell production, and in particular to a battery cell feeding device and formation automation equipment. Background Art

[0002] In the production of battery cells, a forming machine is generally required for forming. In order to improve the forming efficiency, existing forming machines are all large-scale and centralized. Therefore, before forming, each battery cell needs to be collected in a tooling, and then the tooling is placed in the forming machine for centralized forming.

[0003] The existing method of centrally loading the battery cells onto the tooling is manual loading, which is inefficient and the battery cell quality is not high. Summary of the invention

[0004] The present application provides a battery cell feeding device and formation automation equipment, which can solve the problems of low feeding efficiency and low quality of fed battery cells in existing battery cell formation equipment.

[0005] In a first aspect, the present application provides a battery cell loading device.

[0006] The battery cell feeding device includes a manipulator, a deviation correction and shaping mechanism, and a transfer mechanism;

[0007] The manipulator is used to grab the battery cell from the clip and transfer the battery cell to the deflection correction and shaping mechanism, which is used to correct and shape the battery cell;

[0008] The manipulator is used to transfer the battery cells that have completed the correction and shaping process to the tooling on the transfer mechanism;

[0009] The transfer mechanism is used to transfer the tooling carrying the battery cells to the next process, and to reflow the empty tooling to receive the battery cells that have completed the correction and shaping process.

[0010] In the above scheme, a battery cell feeding device is provided, which grabs the battery cell from the clip by a manipulator and transfers it to the correction and shaping mechanism. After the battery cell is corrected and shaped by the correction and shaping mechanism, it is transferred to the empty material tooling of the transfer mechanism by a manipulator, and then the transfer mechanism cooperates with other equipment to transfer the full material tooling carrying the battery cell to the formation fixture in the battery cell formation equipment for formation. At the same time, the transfer mechanism refluxes the empty material tooling and is used again to receive the battery cell that has completed the correction and shaping process. Through the multiple operations of the battery cell feeding device, multiple battery cells are concentrated in the tooling to complete the feeding, which can effectively improve the feeding efficiency, and at the same time, the degree of automation is high and the quality of the fed battery cells is good.

[0011] Optionally, in a possible implementation, the deflection correction and shaping mechanism includes a flipping and photographing mechanism, a deflection correction mechanism, a shaping mechanism, and a flipping and scanning mechanism;

[0012] The manipulator includes a transfer manipulator and a tooling manipulator;

[0013] The transfer manipulator is used to grab the battery cell from the magazine and transfer the battery cell to the flipping and photographing mechanism, which is used to flip and photograph the battery cell;

[0014] The transfer robot is used to grab the battery cell from the flip camera mechanism and transfer the battery cell to the deviation correction mechanism, which is used to correct the deviation of the battery cell;

[0015] The battery cells that have completed the deviation correction are shaped by the shaping mechanism;

[0016] The battery cell that has been shaped is flipped and scanned by the flip scanning mechanism;

[0017] The upper tooling manipulator is used to transfer the battery cells that have completed flipping and code scanning to the empty material tooling on the transfer mechanism.

[0018] In the above scheme, a battery cell loading device with flipping photography, correction, shaping and flipping scanning functions is provided. Different from the prior art, which is a manual loading or regional loading method, this scheme arranges various mechanisms reasonably according to the functional operation attributes to automatically complete the loading of the battery cell: first, the battery cell is taken out from the clip by the transfer manipulator and placed on the flipping photography mechanism. After the battery cell is flipped by the flipping photography mechanism (so that the battery cell is flat), it is photographed to check the appearance of the battery cell. Then, the transfer manipulator grabs the battery cell from the flipping photography mechanism and transfers it to the correction mechanism for position correction, so that the battery cell can enter the downstream process (shaping and flipping scanning process) in the correct posture. The manipulator will be in the correct posture at the shaping mechanism, and the shaping mechanism will shape the air bag, the pole ear and the side sealing edge of the battery cell. Subsequently, the shaped battery cell is placed at the flipping scanning mechanism, and the flipping scanning mechanism flips the battery cell and then scans the surface of the battery cell. After the code scanning is completed, the battery cell is transferred to the tooling by the upper tooling manipulator. Through multiple operations of the battery cell feeding device, multiple battery cells are concentrated in the tooling to complete the loading. Among them, the flipping, photographing, shaping and code scanning of the battery cell are concentrated in the battery cell feeding device, which effectively improves the loading efficiency. At the same time, the degree of automation is high and the quality of the loaded battery cells is good.

[0028] The deflection-correcting plate is used to place the battery cells;

[0029] The deflection correction driving unit drives the deflection correction plate to move along a first direction and a second direction, and the first direction and the second direction are perpendicular to each other.

[0031] The tab shaping assembly is used to flatten the tabs of the battery cell, the air bag shaping assembly is used to flatten the air bag of the battery cell, and the battery cell side shaping assembly is used to flatten the side wall of the battery cell.

[0032] Optionally, in a possible implementation, the flipping and scanning code mechanism includes a second flipping mechanism and a scanning code mechanism;

[0069] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0070] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0071] The present embodiment provides a battery cell feeding device 10, which can solve the problems of low feeding efficiency and low quality of fed battery cells in existing battery cell formation equipment.

[0072] See also Figure 1 and Figure 2 , Figure 1 The three-dimensional structure of the battery cell feeding device 10 in this embodiment at a first viewing angle is shown. Figure 1 The three-dimensional structure of the battery cell feeding device 10 in this embodiment at a second viewing angle is shown.

[0073] The battery cell loading device 10 includes a robot, a deviation correction and shaping mechanism 10A and a transfer mechanism 10B.

[0074] The manipulator is used to grab the battery cell from the clip 10a and transfer the battery cell to the deviation correction and shaping mechanism 10A. The deviation correction and shaping mechanism 10A is used to correct the deviation and shape the battery cell.

[0075] The robot is used to transfer the battery cells that have completed the correction and shaping process to the empty material tooling on the transfer mechanism 10B.

[0076] The transfer mechanism 10B is used to transfer the full tooling containing battery cells to the next process, and to reflow the empty tooling to receive the battery cells that have completed the correction and shaping process.

[0077] It should be noted that the manipulator grabs the battery cell from the clip 10a in the clip feeding mechanism. The full tooling is the tooling 10b with battery cells, and the empty tooling is the tooling 10b without battery cells. The next process referred to above refers to the process of transferring the full tooling to the formation fixture in cooperation with other equipment, such as a transfer device, when the full tooling is transported to the designated position by the transfer mechanism 10B.

[0078] The deviation correction and shaping mechanism 10A includes a flipping and photographing mechanism 11, a first dust removal mechanism 12, a second dust removal mechanism 13, a deviation correction mechanism 14, a shaping mechanism 15, an air bag punching mechanism 16 and a flipping and scanning mechanism 17.

[0079] The manipulator is used to grab the battery cell from the clip 10a and transfer the battery cell to the flipping and photographing mechanism 11, and the flipping and photographing mechanism 11 is used to flip and photograph the battery cell.

[0080] The robot arm is used to grab the battery cell from the flipping and photographing mechanism 11 and transfer the battery cell to the deviation correction mechanism 14, and the deviation correction mechanism 14 is used to correct the deviation of the battery cell.

[0081] The first dust removal mechanism 12 is located between the flipping and photographing mechanism 11 and the correcting mechanism 14 . When the robot transfers the battery cell from the flipping and photographing mechanism 11 to the correcting mechanism 14 , the first dust removal mechanism 12 removes dust from the bottom surface of the battery cell.

[0082] The second dust removal mechanism 13 is disposed above the deviation correcting mechanism 14 and is used for removing dust from the front side of the battery cell located on the deviation correcting mechanism 14 .

[0083] The manipulator is used to grab the battery cell from the deviation correction mechanism 14 and transfer the battery cell to the shaping mechanism 15, and the shaping mechanism 15 is used to shape the battery cell.

[0084] The manipulator is used to grab the battery cell from the shaping mechanism 15 and transfer the battery cell to the air bag punching mechanism 16, and the air bag punching mechanism 16 is used to punch the air bag of the battery cell.

[0085] The robot is used to transfer the battery cells that have been shaped, that is, the battery cells that have been punched, to the flipping and scanning mechanism 17, and the flipping and scanning mechanism 17 is used to flip and scan the battery cells.

[0086] The robot is used to transfer the battery cells that have completed flipping and code scanning to the tooling 10b (empty material tooling) on ​​the transfer mechanism 10B.

[0087] Among them, Figure 1 A magazine 10a and a tool 10b are shown.

[0088] In the above-mentioned embodiment, a battery cell feeding device 10 is provided which integrates the functions of flipping and photographing, correcting, shaping and flipping and scanning codes.

[0089] Different from the prior art, which uses manual loading or area-based loading, the present solution rationally arranges various mechanisms according to functional operation attributes to automatically complete the loading of battery cells: first, the battery cell is taken out from the clip 10a by a robot and placed on the flipping and photographing mechanism 11. After the battery cell is flipped by the flipping and photographing mechanism 11 (since the battery cell is placed vertically in the clip 10a, the battery cell needs to be laid flat), the battery cell is photographed to inspect the appearance of the battery cell.

[0090] Then, the robot grabs the battery cell from the flipping and photographing mechanism 11 and transfers it to the correction mechanism 14 for position correction, so that the battery cell can enter the downstream process (shaping and flipping and scanning processes) in the correct posture.

[0091] In the process of the robot arm transferring the battery cell from the flipping and photographing mechanism 11 to the correction mechanism 14, the first dust removal mechanism 12 removes dust from the bottom surface of the battery cell. When the battery cell is in the correction mechanism 14, the second dust removal mechanism 13 removes dust from the front surface of the battery cell to make the surface of the battery cell dust-free, avoiding dust and impurities on the surface of the battery cell from affecting the subsequent shaping process and rib punching process, thereby ensuring the quality of the battery cell.

[0092] After the deviation correction is completed, the robot grasps the battery cell in the correct posture and transfers it to the shaping mechanism 15, so that the shaping mechanism 15 shapes the air bag, the pole ear and the side sealing edge of the battery cell.

[0093] Subsequently, the shaped battery cell is transferred by the robot to the air bag punching mechanism 16, which punches the air bag of the battery cell to enhance the sealing performance of the air bag.

[0094] After the battery cell is punched, the robot will grab the battery cell and transfer it to the flipping and scanning mechanism 17. The flipping and scanning mechanism 17 will flip the battery cell and then scan the surface of the battery cell.

[0095] After the code scanning is completed, the good battery cells are transferred to the tooling 10b of the transfer mechanism 10B by the robot arm. At the same time, the transfer mechanism 10B will reflow the empty material tooling and take over the battery cells again.

[0096] Through multiple operations of the battery cell feeding device 10, multiple battery cells are concentrated in the tooling 10b to complete the feeding. Among them, the turning, photographing, shaping and code scanning processes of the battery cells are concentrated in the battery cell feeding device 10, thereby effectively improving the feeding efficiency, and at the same time, the degree of automation is high, and the quality of the fed battery cells is good.

[0097] It should be noted that, in the present embodiment, the first dust removal mechanism 12 and the second dust removal mechanism 13 are negative pressure dust removal mechanisms, and dust is removed from the bottom and front surfaces of the battery cells.

[0098] In other specific embodiments, under certain circumstances, such as a dust-free environment or when dust removal is no longer required on the surface of the battery cell, the first dust removal mechanism 12 and the second dust removal mechanism 13 may be eliminated.

[0099] In other specific embodiments, under certain circumstances, such as when the air bag of the battery cell has good sealing performance, the air bag punching mechanism 16 may be omitted.

[0100] It should be noted that in order to improve the loading efficiency, the manipulator, the flipping and photographing mechanism 11, the first dust removal mechanism 12, the second dust removal mechanism 13, the correction mechanism 14, the shaping mechanism 15, the air bag punching mechanism 16 and the flipping and scanning mechanism 17 can all process two battery cells at the same time. In other specific embodiments, there is no limit on the number of battery cells that can be processed by the above structure, and it can only process one battery cell, or three, four or other battery cells.

[0101] See also Figure 2 as well as Figure 3 , Figure 3 The partial structure of the battery cell feeding device 10 in this embodiment is shown.

[0102] Among them, the flipping photographing mechanism 11, the first dust removal mechanism 12, the deviation correction mechanism 14, the shaping mechanism 15, the air bag punching mechanism 16 and the flipping code scanning mechanism 17 are arranged in a row, and the second dust removal mechanism 13 is arranged above the deviation correction mechanism 14.

[0103] The robot comprises a transfer robot 20 and an upper tooling robot 22. The deviation correction and shaping mechanism 10A further comprises a transport robot 21.

[0104] The transfer robot 20 is used to grab the battery cells from the clip 10 a and transfer the battery cells to the flipping and photographing mechanism 11 , and transfer the battery cells from the flipping and photographing mechanism 11 to the deviation correcting mechanism 14 .

[0105] The transport robot 21 is used to transfer the battery cells from the deviation correction mechanism 14 to the shaping mechanism 15 , and to transfer the battery cells from the air bag punching mechanism 16 to the flipping and scanning mechanism 17 .

[0106] The upper tooling manipulator 22 is used to transfer the battery cells that have completed flipping and code scanning to the tooling 10b.

[0107] The transfer robot 20 and the upper tooling robot 22 are four-axis grasping robots in this embodiment, which are respectively close to the flipping camera mechanism 11 and the flipping code scanning mechanism 17 to complete the work of taking materials from the magazine 10a and upper tooling 10b.

[0108] See also Figure 4 , Figure 4 The specific structure of the transport robot 21 is shown.

[0109] The transport robot 21 includes a frame 210 , a mounting frame 211 and a gripping mechanism 212 .

[0110] The frame 210 is arranged according to the position layout of the flipping photographing mechanism 11 , the first dust removing mechanism 12 , the deviation correcting mechanism 14 , the shaping mechanism 15 , the air bag punching mechanism 16 and the flipping code scanning mechanism 17 .

[0111] The grabbing mechanism 212 is disposed on the mounting frame 211 , and the mounting frame 211 is movably disposed on the frame 210 , so that the grabbing mechanism 212 can grab the battery cells on the deviation correction mechanism 14 and move the battery cells to the shaping mechanism 15 and the flipping and scanning mechanism 17 .

[0112] The gripping mechanism 212 includes a lifting mechanism 2120 and an adsorption mechanism 2121 . The lifting mechanism 2120 is disposed on the mounting frame 211 . The lifting mechanism 2120 drives the adsorption mechanism 2121 to rise and fall. The adsorption mechanism 2121 is used to adsorb the battery cell.

[0113] The frame 210 is provided with a guide rail 2100 and a mounting frame driving device 2101 , the mounting frame 211 is provided with a slider, the slider is slidably arranged on the guide rail 2100 , and the mounting frame driving device 2101 drives the mounting frame 211 to slide on the frame 210 .

[0114] There are two lifting mechanisms 2120, and the two lifting mechanisms 2120 are arranged at intervals on the mounting frame 211. There are four adsorption mechanisms 2121, and every two adsorption mechanisms 2121 correspond to one lifting mechanism 2120. One adsorption mechanism 2121 arranged on the same lifting mechanism 2120 adsorbs and clamps one battery cell. That is, one lifting mechanism 2120 controls the lifting and lowering of two adsorption mechanisms 2121 to grab and transfer two battery cells, and the two lifting mechanisms 2120 act on four battery cells together.

[0115] It should be noted that since four battery cells can be grabbed at the same time, efficiency can be improved. For example, the battery cells can be grabbed from the correction mechanism 14 to the shaping mechanism 15, and the battery cells can be grabbed from the shaping mechanism 15 to the airbag punching mechanism 16 at the same time.

[0116] It should be noted that, in the present embodiment, the lifting mechanism 2120 is a cylinder. In other specific implementations, the lifting mechanism 2120 may be other mechanical structures with a lifting function.

[0117] Optionally, in a possible implementation, the flipping camera mechanism 11 includes a first flipping mechanism 110 and a camera 111 .

[0118] Among them, see Figure 5 , Figure 5 The specific structure of the first turning mechanism 110 in this embodiment is shown.

[0119] The first flipping mechanism 110 includes a bracket 1100 , a gripping portion 1101 and a flipping driving portion 1102 . The gripping portion 1101 is rotatably disposed on the bracket 1100 , and the flipping driving portion 1102 is used to drive the gripping portion 1101 to rotate 90 degrees.

[0120] It should be noted that the gripping portion 1101 is formed with two suction cups 1101a to grip two battery cells and flip the two battery cells at the same time. In this embodiment, the flipping driving portion 1102 is a motor, and the output shaft of the motor is passed through the bracket 1100 and connected to the gripping portion 1101. The gripping portion 1101, that is, the two suction cups 1101a, is flipped 90 degrees through the rotation of the motor.

[0121] The flipping and photographing mechanism 11 further includes a camera mounting frame 112, which is disposed on the side of the first flipping mechanism 110, and the camera 111 is fixed on the camera mounting frame 112. When the first flipping mechanism 110 flips the battery cell 90 degrees, the camera 111 takes a picture of the surface of the battery cell to detect the appearance of the battery cell.

[0122] See also Figure 6 , Figure 6 The specific structure of the deviation correcting mechanism 14 in this embodiment is shown.

[0123] The correction mechanism 14 includes a correction plate 140 and a correction drive unit 141, wherein Figure 6 The number of the deflection correction plates 140 and the deflection correction driving units 141 is two, and each deflection correction unit is driven by the corresponding deflection correction driving unit 141 to achieve simultaneous deflection correction of two battery cells.

[0124] The deflection-correcting plate 140 is used to place the battery cells.

[0125] The deflection correcting driving unit 141 drives the deflection correcting plate 140 to move along a first direction and a second direction, and the first direction and the second direction are perpendicular to each other.

[0126] It should be noted that, after the transfer robot 20 grabs the battery cell from the flipping camera mechanism 11 and transfers the battery cell to the correction plate 140, the correction drive unit 141 works to drive the correction plate 140 to move in the first direction and the second direction so that the battery cell is in the correct posture, which facilitates the transport robot 21 to transport the battery cell in the correct posture to other processes.

[0127] It should be noted that in Figure 6 The orientations of the first direction and the second direction are shown in FIG. 1 , wherein the first direction and the second direction are two directions perpendicular to each other on a plane.

[0128] It should be noted that the deviation-correcting driving unit 141 includes a first motor 1410 , a second motor 1411 , a base plate 1412 and a displacement plate 1413 .

[0129] The first motor 1410 is arranged on the substrate 1412 and drives the displacement plate 1413 to move in the first direction, and the correction plate 140 moves in the second direction relative to the displacement plate 1413. The second motor 1411 drives the correction plate 140 to move, so that the correction plate 140 on which the battery cell is placed can move in the first direction and the second direction.

[0130] It should be noted that, in order to improve the accuracy of the correction, a third motor may be provided, and the third motor may drive the substrate 1412 to rotate so as to correct the angle of the battery cell.

[0131] Optionally, in a possible implementation, the shaping mechanism 15 includes a pole ear shaping component 150 , an air bag shaping component 151 and a battery cell side shaping component 152 .

[0132] See also Figure 7 and Figure 8 , Figure 7 for Figure 3 The enlarged image of point VII in the middle. Figure 8 Detailed structure of the airbag shaping assembly 151 in this embodiment.

[0133] The tab shaping assembly 150 is used to flatten the tabs of the battery cell, the air bag shaping assembly 151 is used to flatten the air bag of the battery cell, and the battery cell side shaping assembly 152 is used to flatten the side wall of the battery cell.

[0134] Among them, the shaping mechanism 15 also includes a shaping support platform 153, and the airbag shaping component 151 and the battery cell side shaping component 152 are respectively arranged on the sides of the shaping support platform 153 to act on the airbag and the side of the battery cell respectively.

[0135] The airbag shaping assembly 151 includes a shaping base 1510, an airbag flattening mechanism 1511, and a first transverse driving unit 1512. The airbag flattening mechanism 1511 is slidably disposed on the shaping base 1510 and driven by the first transverse driving unit 1512. When the battery cell is about to be placed on the shaping support platform 153, the airbag flattening mechanism 1511 can be driven by the first transverse driving unit 1512, so that the airbag of the battery cell can be smoothly placed on the shaping support platform 153 without being interfered by the airbag flattening mechanism 1511. When the airbag of the battery cell needs to be shaped, the first transverse driving unit 1512 drives the airbag flattening mechanism 1511 to move transversely to move above the airbag of the battery cell, thereby shaping. It should be noted that in this embodiment, the first transverse driving unit 1512 is a cylinder.

[0136] Among them, the air bag flattening mechanism 1511 includes an upper pressure shaping part 30 and a lower pressure shaping part 31, the upper pressure shaping part 30 includes an air bag upper pressure block 300 and an air bag upper pressure cylinder 301, and the lower pressure shaping part 31 includes an air bag lower pressure block 310 and an air bag lower pressure cylinder 311. The air bag upper pressure block 300 is driven by the air bag upper pressure cylinder 301 to be raised and lowered. The air bag lower pressure block 310 is driven by the air bag lower pressure cylinder 311 to be raised and lowered. When the air bag upper pressure block 300 and the air bag lower pressure block 310 are close to each other, the air bag of the battery cell can be flattened, thereby completing the shaping of the battery cell air bag.

[0137] It should be noted that there are two upper pressing shaping parts 30 and two lower pressing shaping parts 31 respectively, so as to shape the air bags of two battery cells at the same time.

[0138] The pole lug shaping assembly 150 includes a pole lug pressing portion 1500 and a second transverse driving portion 1501. The pole lug shaping assembly 150 is located at the end of the shaping support platform 153. When the battery cell is about to be placed on the shaping support platform 153, the second transverse driving portion 1501 drives the pole lug pressing portion 1500 away from the shaping support platform 153, so that the pole lug of the battery cell can be smoothly placed on the shaping support platform 153. When the pole lug of the battery cell is being shaped, the second transverse driving portion 1501 drives the pole lug pressing portion 1500 to approach the shaping support platform 153, and the pole lug pressing portion 1500 is above the pole lug of the battery cell.

[0139] The tab pressing part 1500 includes a tab pressing block 1502 and a tab pressing cylinder 1503. When the tab of the battery cell needs to be shaped, the tab pressing cylinder 1503 drives the tab pressing block 1502 to descend, so that the tab pressing block 1502 presses the tab flat on the shaping support platform 153 to complete the shaping of the tab.

[0140] Among them, it should be noted that the number of the pole ear shaping components 150 is two, and the two pole ear shaping components 150 are respectively arranged at the two ends of the shaping support platform 153 to achieve the simultaneous shaping of the pole ears of the two battery cells. It should be noted that since the two pole ear shaping components 150 are arranged at the two ends of the shaping support platform 153, the battery cells processed at the same time need to be distributed in a mirror image, that is, when shaping, the pole ears of the two battery cells need to be placed at the two ends of the shaping support platform 153 respectively.

[0141] It should be noted that there are two battery cell side shaping components 152 for shaping the side parts of two battery cells.

[0142] The battery cell side shaping assembly 152 includes a side leveling cylinder 1520 and a side leveling block 1521. The side leveling cylinder 1520 drives the side leveling block 1521 to rise and fall, and the side leveling block 1521 is used to level the side of the battery cell.

[0143] See also Fig. 9 and Fig.10 , Fig. 9 for Figure 3 The enlarged image of the middle IX, Fig.10 Detailed structure of the rib assembly 163 in this embodiment.

[0144] The airbag rib punching mechanism 16 includes a rib punching base 160 , a rib punching support platform 161 , a third transverse driving unit 162 and a rib punching assembly 163 .

[0145] The transport robot 21 grabs the battery cell from the shaping support platform 153 and transfers the battery cell to the rib punching base 160 , and performs rib punching through the rib punching assembly 163 .

[0146] The rib support platform 161 is slidably disposed on the rib base 160, and the rib assembly 163 is disposed on the side of the rib base 160. The third transverse driving unit 162 is in transmission connection with the rib support platform 161. When the air bag of the battery cell needs to be ribbed, the third transverse driving unit 162 drives the rib support platform 161 to slide, so that the battery cell moves toward the rib assembly 163, so that the rib assembly 163 can act on the air bag of the battery cell.

[0147] The rib assembly 163 includes an upper rib portion 1630 and a lower rib portion 1631. The upper rib portion 1630 includes a rib upper pressure block 40 and a rib upper pressure cylinder 41, and the lower rib portion 1631 includes a rib lower pressure block 42 and a rib lower pressure cylinder 43. The rib upper pressure block 40 is driven by the rib upper pressure cylinder 41 to be raised and lowered. The rib lower pressure block 42 is driven by the rib lower pressure cylinder 43 to be raised and lowered. When the rib upper pressure block 40 and the rib lower pressure block 42 are close to each other, the air bag of the battery cell can be ribbed, thereby completing the sealing and strengthening of the battery cell air bag.

[0148] It should be noted that the number of the upper pressing rib part 1630 and the number of the lower pressing rib part 1631 are respectively two, so as to punch the air bags of two battery cells at the same time.

[0149] Alternatively, in one possible implementation, please refer again to Figure 3 The flipping and scanning code mechanism 17 includes a second flipping mechanism 170 and a scanning code mechanism 171 .

[0150] The second flipping mechanism 170 is used to flip the battery cell 90 degrees so that the surface of the battery cell can be scanned by the scanning mechanism 171 .

[0151] The specific structure of the second flipping mechanism 170 is the same as that of the first flipping mechanism 110 , and will not be described in detail herein.

[0152] It should be noted that this embodiment also provides a chemical formation automation equipment 50. Fig.11 .

[0153] The formation automation equipment 50 includes a transfer device 51 , a formation fixture 52 , a material unloading device 53 and the battery cell loading device 10 provided above.

[0154] The battery cell loading device 10 , a plurality of formation fixtures 52 and a unloading device 53 are arranged in sequence.

[0155] The battery cell loading device 10 is used to transfer the battery cells in the clip 10a to the tooling 10b and transfer the tooling carrying the battery cells to the transfer device 51. The transfer device 51 is used to transfer the tooling 10b to the formation fixture 52 and to move the tooling 10b formed by the formation fixture 52 to the unloading device 53.

[0156] It should be noted that the unloading device 53 returns the empty tooling and transfers the empty tooling to the battery cell loading device 10 through the transfer device 51. In this embodiment, the transfer device 51 transfers the empty tooling to the transfer mechanism 10B in the battery cell loading device 10 to realize repeated loading process.
