Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of soft package battery processing, in particular to a soft package battery assembling device and method thereof. BACKGROUND

[0002] At present, soft package batteries are widely used in the fields of power batteries and consumer electronics due to their high energy density, good safety, and flexible design. However, there are still many technical bottlenecks in the current soft package battery processing and production process, which seriously restricts the upgrading of the industry.

[0003] From the production process, the key problem to be solved is the high proportion of manual participation. In the core processes of pole piece, glue application, stacking, and shell installation, manual operation accounts for as high as 40%-60%, which not only limits the production capacity to the size of manpower, but also causes quality problems such as unstable pole piece burr control precision and deviation of cell alignment due to the difference in operator skill level. Data shows that the defective rate caused by manual operation is 15-20 percentage points higher than that of automated production lines, especially in the production of high-capacity batteries, the risk of internal short circuit caused by manual intervention increases significantly.

[0004] At the same time, the problem of insufficient continuity of production system equipment is more prominent. In the existing production line, although the single machine devices such as pole piece, glue application, stacking, and shell installation have improved the degree of automation, the material transmission between devices relies on manual transfer or non-standard connection devices, resulting in unbalanced beat matching between processes. This continuity defect also causes production data faults, and the process parameters generated by independent operation of each device cannot be interacted in real time, making it difficult to realize whole-process quality traceability and process optimization.

[0005] More seriously, the above problems are superimposed, forming a vicious cycle. The inefficiency of manual operation forces enterprises to adopt a production mode of "multiple shifts and high manpower", resulting in high production costs; and the poor connection of equipment prolongs the product in-process time, increasing the quality risks of environmental dust pollution and cell moisture.

DETAILED DESCRIPTION

[0059] In order to better understand the present application, the content of the present application is further illustrated below in combination with examples, but the content of the present application is not limited to the following examples.

[0060] As Figure 1 , Figure 2 and Figure 3As shown, a soft package battery assembly device has sequentially arranged feeding assembly 2, tab processing assembly 3, rubberizing assembly 4, stacking assembly 5, conveying member 6, bending assembly 7, tab welding assembly 10, measuring assembly 11, upper shell assembly 13, first welding assembly 14, overturning assembly 15, second welding assembly 16, detection assembly 17 and offline mechanical arm 18. Feeding assembly 2 can transmit the electric core conveying member 1 to grab and stably place the electric core to tab processing assembly 3. The tab of the electric core is trimmed by tab processing assembly 3 and then is transmitted to rubberizing assembly 4 to be rubberized. After the rubberizing is completed, the electric core is grabbed and stacked by stacking assembly 5 in sequence to form, and then is placed on the first clamping tray 19 arranged on conveying member 6. The first opening and closing assembly 1302 arranged on conveying member 6 is used to assist the opening of the first clamping tray 19 to cooperate with stacking assembly 5 to place the stacked electric core. Then, conveying member 6 transmits the first clamping tray 19 on which the electric core is placed to assembly station 8 to facilitate the staff to install the bus bar by placing the first clamping tray 19 on which the electric core is placed, and to position the bus bar and the electric core by closing the first clamping tray 19. After the installation of the bus bar is completed, conveying member 6 transmits the closed first clamping tray 19 on which the electric core and the bus bar are arranged to bending assembly 7 to bend the tab arranged on the electric core to connect the bus bar to complete the preprocessing of the electric core. Tab welding assembly 10 can reinforce the tab of the stacked electric core after the tab is stacked and bent. Then, conveying member 6 transmits the reinforced stacked electric core to upper shell assembly 13 to replace the first clamping tray 19 used by tab welding assembly 10 with the second clamping tray 20 arranged on upper shell assembly 13. The second clamping tray 20 uses a resilient structure to achieve the clamping and positioning of the stacked electric core and the shell, and can be easily opened and closed to improve the efficiency of the device in overturning and welding the shell, that is, to improve the efficiency of processing the battery. This facilitates the rapid welding of first welding assembly 14, overturning assembly 15 and second welding assembly 16. After the welding of the shell of the electric core is completed, the detection assembly 17 detects the electric core, and the offline mechanical arm 18 clamps the electric core into a box after the detection to facilitate the subsequent transfer and use.

[0061] As shown in Figure 4 and Figure 5 Before feeding assembly 2 places the electric core to tab processing assembly 3, in order to avoid the contact or interference of the electric core in the conveying process when the electric core is processed on tab processing assembly 3, the adjacent electric cores need to maintain the fixed spacing. Therefore, feeding assembly 2 includes adjustment assembly 204 arranged on distance adjustment table 206 and used to adjust the spacing of the electric core. In the embodiment, the number of adjustment assembly 204 is two, and they are distributed along the width direction of the electric core. One adjustment assembly 204 can adjust two electric cores, and two adjustment assemblies 204 can adjust four electric cores at a time to make the spacing of the adjacent two electric cores in the four electric cores meet the requirements of tab processing assembly 3 on the spacing of the electric core.

[0062] The adjusting assembly 204 comprises two first bearing plates 2043 arranged oppositely and capable of moving towards each other or moving away from each other. The battery cell on the battery cell conveying member 1 is transferred to the first bearing plate 2043 through the second mechanical arm 201 and the transfer plate 202 comprised in the feeding assembly 2, and is transferred to the transmission member 401 applied on the tab processing assembly 3 through the placing member 203 after the battery cell on the first bearing plate 2043 is adjusted in distance. The first bearing plate 2043 is in sliding connection with the distance adjusting table 206, and two groups of sliding members 2042 corresponding to the two groups of first bearing plates 2043 are fixedly connected to the distance adjusting table 206. The sliding member 2042 can assist the sliding of the first bearing plate 2043. The sliding member 2042 comprises a first sliding rail, the number of the first sliding rail in each group is two, and the first sliding rails in each group are distributed along the width direction of the first bearing plate 2043. A first sliding block corresponding to the two first sliding rails is fixedly connected to the first bearing plate 2043, and the first sliding block can slide along the sliding rail. A fourth cylinder 2041 for driving the two first bearing plates 2043 to move towards each other and move away from each other is arranged between the two first bearing plates 2043. The fourth cylinder 2041 is fixedly installed on the distance adjusting table 206 and located below the first bearing plate 2043. Two pistons of the fourth cylinder 2041 are fixedly connected to the corresponding first bearing plates 2043 respectively. When the two first bearing plates 2043 move towards each other, the distance between the two first bearing plates 2043 decreases. When the two first bearing plates 2043 move away from each other, the distance between the two first bearing plates 2043 increases. A deviation preventing block 2044 is fixedly connected to the edge of the first bearing plate 2043 towards the tab processing assembly 3. The top end of the deviation preventing block 2044 is higher than the upper surface of the first bearing plate 2043, and the deviation preventing block 2044 limits the battery cell on the first bearing plate 2043 to avoid deviation.

[0063] The second mechanical arm 201 driving the transfer plate 202 is arranged on the distance adjusting table 206. The second mechanical arm 201 can drive the transfer plate 202 to move in multiple axes. A plurality of groups of second suction cups for adsorbing battery cells are arranged on the transfer plate 202. Each group of second suction cups corresponds to one battery cell. In the embodiment, the second suction cups are divided into four groups. The distance between the two adjacent groups of second suction cups corresponds to the distance between the battery cells in the frame, so that one group of second suction cups adsorbs one battery cell. The number of second suction cups in each group is four and is fixedly arranged on both sides of the transfer plate 202. Specifically, two second suction cups in each group are arranged on one side of the transfer plate 202, and the other two are arranged on the other side of the transfer plate 202. The second suction cups on the same side are distributed along the length direction of the transfer plate 202. The second suction cups are fixedly connected to the transfer plate 202 through “L” type connecting pieces. The connection between the “L” type connecting piece and the transfer plate 202 is bolted connection.

[0064] The placing part 203 comprises a second connecting plate corresponding to each first bearing plate 2043, and a plurality of pull-up suction cups 2032 for adsorbing the battery cell are fixedly arranged on the second connecting plate. The second connecting plate is driven by a pull-up air cylinder 2031 to vertically displace, and the pull-up air cylinder 2031 is connected with a placing row frame 2033 arranged on the distance adjusting table 206, so that the second connecting plate can horizontally reciprocate and vertically reciprocate. The number of the second connecting plates is the same as the number of the first bearing plates 2043, that is, the number of the second connecting plates is four, and the spacing between the adjacent two second connecting plates matches the spacing of the battery cells in the tab processing assembly 3. The second connecting plate is fixedly provided with a plurality of pull-up suction cups 2032 for fixing the battery cell. Four pull-up suction cups 2032 are arranged on each second connecting plate, and the four pull-up suction cups 2032 are divided into two parts and respectively located on both sides of the second connecting plate. Each side of the two pull-up suction cups 2032 is fixedly connected with the second connecting plate through a "Z"-shaped connecting piece.

[0065] When the battery cell on the first bearing plate 2043 is translated, the placing row frame 2033 drives the first support plate to slide, thereby driving the pull-up suction cup 2032 to be located above the corresponding battery cell. Then, the pull-up air cylinder 2031 drives the pull-up suction cup 2032 to move downward to contact and adsorb the battery cell.

The checking member 501 and the stacking mechanical arm 502 are both provided with two to cooperate with the two storage racks 5051 arranged on the rotating table 5054 to improve the stacking efficiency of the battery cell. After the stacking of the battery cell is completed, the rotating table 5054 will rotate the controlled storage rack 5051 to the working range of the stacking mechanical arm 502. At the same time, the gland plate 5053 of the other storage rack 5051 will be driven by the stacking row frame 5052 to separate and move to the working range of the transfer mechanical arm 507. Then the transfer mechanical arm 507 will grab and transfer to convey the stacked battery cell to the first clamping tray 19 arranged on the conveying member 6. At the same time, the opening assembly 506 arranged in the conveying member 6 is used to open the first clamping tray 19, so that the transfer mechanical arm 507 can place the stacked battery cell into the first clamping tray 19. Then the conveying member 401 will convey the first clamping tray 19 in the open state and with the stacked battery cell inside to the assembly station 8 to install the busbar and close the first clamping tray 19.

The ring formed by the plurality of connecting columns is connected with the plurality of connecting holes opened in the ring shape on the rotating disc, to facilitate the adjustment of the operator. The positioner, the control motor, the driving motor, and the telescopic cylinder can be controlled by the electromechanical system. Specifically, how the electromechanical system is set, how it is controlled, and how it is adjusted and applied should all be understood as prior art, so as to be controlled by the operator after adjustment.

The opposite surfaces of the fixed clamping jaw and the movable clamping jaw are provided with protective pads made of elastic rubber material to protect the surface of the soft package battery cell in the battery assembly during clamping of the movable clamping jaw and the fixed clamping jaw. The control screw can control the displacement of the movable clamping jaw, so that the distance between the movable clamping jaw and the fixed clamping jaw is convenient for the operator to operate. The end of the control screw penetrating through the movable clamping jaw and the corresponding bearing seat is fixedly provided with a butt joint wheel which can cooperate with the corresponding opening assembly 506 to assist the operator to adjust the position of the movable clamping jaw by machine. The clamping assembly includes a positioning plate arranged on one side of the placing plate in the length direction, and the positioning plate is vertically slidably arranged on the bottom plate. Specifically, the positioning plate is fixedly provided with a slide strip on both sides in the width direction of the placing plate, and the slide strip is slidably arranged on the slide rail seat fixed on the bottom plate. The positioning plate is provided with an adjusting waist groove, and a plurality of plug-in blocks are connected to the adjusting waist groove through screws, so that the operator can adjust the position of the plug-in block according to different soft package battery processing conditions. The plug-in block can be inserted between the bus plate and the soft package battery cell to position the distance between the bus plate and the soft package battery cell, and align the soft package battery cell in the length direction to the designed position, and make the tab penetrating through the bus plate and bending in stable contact with the bus plate. The plug-in block can cooperate with the stabilizing block fixedly arranged on the top surface of the positioning plate to form a clamping area to clamp and position the bus plate. A power groove is formed in the center of the positioning plate, and the power groove is arranged in an inclined manner. A power column is slidably arranged in the power groove. Specifically, a wear-resistant wheel is rotatably arranged outside the power column to reduce the mutual friction of the power column when sliding in the power groove, so that the power column can easily slide in the power groove. The power column is fixedly connected with a pushing slide plate, and the pushing slide plate is slidably arranged on the supporting slide rail on the bottom plate, and the pushing slide plate is provided with a screw column. In specific use, the operator can drive the pushing slide plate to drive the power column and the wear-resistant wheel to displace in the power groove, and then cooperate with the inclined power groove to make the positioning plate stably vertically displace under the support of the slide strip and the slide rail seat. When the positioning plate vertically upwardly displaces, the plug-in block will first be inserted between the bus plate and the soft package battery cell, and then guide the soft package battery cell and the bus plate to maintain a corresponding distance, and guide the soft package battery cell to displace to the designed position. With the gradual rising of the positioning plate, the bus plate will enter the clamping area to further position the bus plate.After the positioning plate is moved into position, the operator can rotate the screw to press the bottom plate to stabilize the position of the positioning plate, thereby maintaining the stability of the subsequent soft-pack battery cell processing. After repeatedly operating the two clamping assemblies, the two busbars and the plurality of soft-pack battery cells can be positioned at the designed positions on the placement plate. Finally, the operator can operate the clamping assembly to clamp the plurality of soft-pack battery cells to process the subsequent battery assembly.

[0094] The cover plate member includes a pressing plate for covering the top of the plurality of soft-pack battery cells, and a clamping hole is formed in the pressing plate. The clamping hole can be clamped with the clamping head fixed on the top of the movable clamping jaw and the fixed clamping jaw to position itself. At the same time, the clamping hole can also limit the position of the fixed clamping jaw and the movable clamping jaw to maintain the stability of the fixed clamping jaw and the movable clamping jaw in positioning the plurality of soft-pack battery cells. The two sides of the length direction of the cover plate member are provided with a plurality of fixing blocks and a plurality of auxiliary blocks. The auxiliary block and the fixing block can form a positioning area for clamping the busbar, and the positioning area can cooperate with the clamping area to further stabilize the relative position of the busbar. The auxiliary block is connected with the matching waist groove formed in the pressing plate through a screw, so as to facilitate the operator to adjust the position of the auxiliary block to adapt to the tab of the soft-pack battery cell.

[0095] The opening assembly 506 includes a docking column that can cooperate with the docking wheel included in the first clamping tray 19. The docking wheel can drive the control screw to rotate, and then the operator can move the movable clamping jaw to expose enough space for the placement plate. Then the operator can place the corresponding number of soft-pack battery cells on the placement plate. Next, the operator can sequentially push the two clamping assemblies to stably position the busbar connected by the tabs of the soft-pack battery cells, and stably place the plurality of soft-pack battery cells at the designed position of the placement plate. After the plurality of soft-pack battery cells are clamped and positioned, the cover plate member can be placed on the top of the plurality of soft-pack battery cells, and the clamping hole can be clamped with the clamping head provided on the top of the fixed clamping jaw and the movable clamping jaw to further stabilize the relative position of the fixed clamping jaw and the movable clamping jaw, i.e. to stabilize the clamping of the plurality of soft-pack battery cells.

[0096] As Figure 17As shown, the bending assembly 7 has a fourth support frame 701 provided with the conveying member 6 at the center, and a work frame 702 provided on the fourth support frame 701, the work frame 702 is sequentially provided with a bending member 706 and a flattening assembly 708 along the conveying direction of the conveying member 6, and the work frame 702 is provided with a measuring assembly 703 for determining the position of the first clamping tray 19 conveyed by the conveying member 6. After the first clamping tray 19 conveyed by the conveying member 6 is detected by the measuring assembly 703, two lifting assemblies 704 will be operated to stably hold and lift the first clamping tray 19 at the corresponding position upward. Specifically, the lifting assembly 704 includes a lifting cylinder provided in the fourth support frame 701 and a butt joint plate provided on the moving end of the lifting cylinder, the butt joint plate can be clamped with the bottom surface of the first clamping tray 19, and then stably push the corresponding first clamping tray 19 upward, so that the tab included in the plurality of battery cells clamped by the first clamping tray 19 corresponds to the bending member 706 or the flattening assembly 708 to perform the corresponding processing procedure. The bending member 706 and the flattening assembly 708 can sequentially bend and flatten the tabs of the plurality of battery cells.

[0097] The conveying member 6 is a structure of two chain wheels driving two chains arranged at intervals, thereby being able to connect the two side edges of the bottom of the first clamping tray 19, and then stably drive the first clamping tray 19 to displace, so as to improve the processing efficiency of the plurality of battery cells clamped by the first clamping tray 19. Figure 18As shown, the bending piece 706 includes two symmetrically arranged bending rows arranged on the working frame 702, and the bending rows include first rows 7061 arranged on the working frame 702, spaces for the plurality of battery cells are formed between the two first rows 7061, the first rows 7061 drive second rows 7062, the second rows 7062 are provided with connecting frames 7063, the connecting frames 7063 are fixedly provided with third bearing plates 7064 at the bottom, the third bearing plates 7064 are provided with bending plates 7066, the bending plates 7066 can be driven by the first rows 7061 and the second rows 7062 to bend the tabs of the plurality of battery cells lifted by the lifting assembly 704, and can also bend the tabs of the plurality of battery cells at different positions. Specifically, the second rows 7062 drive the bending plates 7066 to approach the tabs, the first rows 7061 drive the second rows 7062 to make the bending plates 7066 press the tabs to bend to the corresponding side, that is, the tabs can be bent to the required direction to adapt to the assembly formula of the corresponding plurality of battery cells, and the formula is a specific positive and negative electrode connection mode. During the bending process, the roller provided at the end of the bending plate 7066 is used to reduce the friction between the bending plate 7066 and the tab, that is, to reduce the damage to the surface of the tab caused by the bending plate 7066, thereby reducing the probability of affecting the subsequent contact of the tab to cause the transmission power quality to decrease. The third bearing plate 7064 is fixedly provided with a limiting frame, the bending plate 7066 is movably connected with the limiting frame through a relief spring and a limiting column, and in the process of bending the tab by the bending plate 7066, the relief spring slows down the hard pushing of the bending plate 7066 during the bending process of the tab, that is, reduces the probability of damage caused by the hard bending of the tab. The bending plate 7066 and the limiting frame are both provided with two, and the spacing between the two bending plates 7066 is equal to the spacing between the two tabs of the plurality of battery cells, so as to simultaneously bend the two tabs of the plurality of battery cells, that is, to improve the efficiency of bending the tabs of the plurality of battery cells. The two limiting frames are slidably connected with impact pieces 7065 along the transmission direction of the conveying piece 6, and the two impact pieces 7065 are driven by a bending cylinder 7067 arranged on the third bearing plate 7064, so as to impact the tab to reinforce the bending degree and flatness of the bent tab after the tab is bent in place by the bending plate 7066.

[0098] As Figure 19As shown, the flattening assembly 708 includes a flattening frame symmetrically arranged on both sides of the tab of the plurality of battery cells, and the flattening frame includes a third row frame 7081 and a fourth row frame 7082 arranged on the working frame 702, and the space for the plurality of battery cells is formed between the two third row frames 7081, and the vertical telescopic frame 7083 is arranged on the fourth row frame 7082, and the vertical telescopic frame 7083 is connected with the vertical bearing block 7086, and the auxiliary plate 7084 is matched with the bearing block 7086, and the end of the auxiliary plate 7084 towards the tab is provided with the roller 7085. Specifically, the third row frame 7081 can drive the fourth row frame 7082 to displace, and then the vertical telescopic frame 7083, the bearing block 7086, the auxiliary plate 7084 and the roller 7085 can be displaced to correspond to the tabs at different positions of the plurality of battery cells. The fourth row frame 7082 can drive the vertical telescopic frame 7083 to approach the tab position, and then the roller 7085 can be pressed through the bent tab by the bearing block 7086 and the auxiliary plate 7084, and then the state of the bent tab can be further reinforced, and the tab bending surface can also be kept flat. The bearing block 7086 and the auxiliary plate 7084 are slidingly matched, and the auxiliary spring is arranged between the end surface of the auxiliary plate 7084 and the movable end of the vertical telescopic frame 7083, so as to adapt to the condition that the fourth row frame 7082 moves too much, and the hard rolling can be changed to soft rolling to a certain extent, so as to reduce the stress concentration of the tab caused by hard pressing, or reduce the tab fracture caused by hard pressing.

[0099] As Figure 18 and Figure 19As shown, the working frame 702 is provided with a pressing assembly 707 at both the bending member 706 and the flattening assembly 708, so as to cooperate with the lifting assembly 704 to press the plurality of battery cells during the processing of the plurality of cell tabs by the bending member 706 and the flattening assembly 708, that is, to reduce the displacement of the plurality of battery cells during the processing of the plurality of cell tabs, so as to ensure the quality of the tab bending of the plurality of battery cells. The pressing assembly 707 comprises a pressing frame 7071 fixedly arranged on the working frame 702, the pressing frame 7071 is arranged between the two first rows of frames 7061 or the two third rows of frames 7081, a pressing cylinder 7072 is fixedly arranged at the center of the pressing frame 7071, a moving plate is fixedly arranged at the extension end of the pressing cylinder 7072, and a pressing plate is elastically connected to one side of the moving plate facing the plurality of battery cells. After the lifting assembly 704 moves the first clamping tray 19 and the plurality of battery cells to a suitable height, the pressing cylinder 7072 drives the moving plate and the pressing plate to press the plurality of battery cells, and then cooperates with the lifting assembly 704 to stabilize the position of the plurality of battery cells, so as to ensure the relative position of the plurality of battery cells during the tab bending process, thereby maintaining the quality of the tab bending. Two slide columns are symmetrically fixedly arranged on one side of the moving plate facing the pressing frame 7071, and the two slide columns are in sliding fit with two slide sleeves arranged on the pressing frame 7071, so as to maintain the stability of the vertical movement of the moving plate, that is, to maintain the accuracy and stability of clamping and positioning the plurality of battery cells. An active column is slidably arranged at each corner of the moving plate away from the pressing frame 7071, and a buffer spring is sleeved on the active column. The arrangement of the buffer spring can reduce the vibration during the extension and retraction of the lifting assembly 704 and the pressing cylinder 7072 when the pressing plate presses the plurality of battery cells, and can also reduce the damage to the plurality of battery cells caused by excessive pressing force of the lifting assembly 704 and the pressing cylinder 7072. The pressing plate is provided with a load connecting plate 7073 fixedly arranged on both sides of the tab of the plurality of battery cells, the load connecting plate 7073 is provided with a detection frame 7074 fixedly arranged on one side of the tab of the plurality of battery cells, and the detection frame 7074 is provided with a position detector 7075 arranged on one side of the plurality of tabs. Specifically, the position detector 7075 comprises an infrared receiving end and an infrared emitting end, and the infrared receiving end and the infrared emitting end are arranged along the distribution direction of the plurality of tabs on one side. During the bending and flattening of the tab, if it is not flat or the bending is not in place, the infrared rays emitted by the infrared emitting end of the position detector 7075 will not be received by the infrared receiving end, and then corresponding feedback can be performed to control the bending member 706 and the flattening assembly 708 to repeat the bending and flattening operation. The flattening assembly 708 can further reinforce the bending stability of the tab after the tab is bent and transported by a certain transportation member 6. The position detector 7075 arranged on the flattening assembly 708 is closer to the corresponding side tab than the position detector 7075 arranged on the bending member 706, thereby further enhancing the stability of the tab bending connection.Specifically, the detection frame 7074 is U-shaped, and the concave part of the detection frame 7074 can cover the corresponding tabs of multiple battery cells, so that the infrared receiver and infrared transmitter are arranged along the distribution direction of multiple tabs on one side to perform detection operations on multiple tabs.

[0100] like Figure 20 As shown, the tab welding assembly 10 has a support frame 1001. Along the length of the support frame 1001, a feeder 1003 and a tab welding component 1005 are arranged sequentially. Importantly, an auxiliary welding component 1002 and a welding guide 1006 are mounted above the feeder 1003. These two components work in conjunction with the tab welding component 1005 to complete the tab welding process. The feeder 1003 is responsible for precisely positioning the first clamping tray 19 and the pouch battery pack conveyed on the transport component 6 to the corresponding positions of the auxiliary welding component 1002 and the welding guide 1006. Subsequently, through adjustment by the feeder 1003, the pouch battery pack is lifted to a specific height, ensuring precise alignment of its tabs with the auxiliary welding component 1002 and the welding guide 1006. Furthermore, this process elevates the pouch battery pack into a relatively independent space, aiming to reduce interference from external factors and thus ensure the accuracy and stability of the tab welding operation. Once the pouch battery pack has moved to the designated position, the auxiliary welding component 1002 adjusts its posture, causing the welding guide 1006 to initially align with the tabs of the pouch battery pack. Simultaneously, the welding guide 1006 performs precise measurements, and the auxiliary welding component 1002 adjusts accordingly to ensure accurate alignment between the welding guide 1006 and the tabs. Next, the welding guide 1006, in conjunction with the tab welding component 1005, welds the tabs. After welding one side of the tabs, the delivery component 1003 rotates the pouch battery pack and repeats the above operation to complete welding on the other side. Once both sides of the tabs are welded, the delivery component 1003 reverses its rotation, transferring the welded pouch battery pack back to the transport component 6 for subsequent processing steps.

[0101] like Figure 21As shown, the structure of the distributing member 1003 includes a transmission frame 10039 corresponding to the conveying member 6, and two transmission shafts 10031 are assembled on the transmission frame 10039, one of which is driven by a driving motor to realize forward and reverse rotation. The two transmission shafts 10031 are each provided with a conveying sprocket to drive the conveying chain 10032 tensioned on the two transmission shafts 10031 to rotate circularly, which aims to improve the transmission efficiency and ensure the stable transmission of the soft-pack battery pack. The conveying chain 10032 is composed of two chains, and the links are arranged in one-to-one correspondence and parallel. The outer side of the link is clamped with the two bottoms of the protective sheet, which is designed in an inverted U shape to protect the surface of the soft-pack battery pack and increase the friction of the soft-pack battery pack during transmission, thereby reducing the risk of slipping on the conveying chain 10032. The driving motor is a forward and reverse stepping motor, which has a simple structure, convenient control, and reliable operation, and can realize the forward and reverse circulation of the two transmission chains, thereby realizing the stable bidirectional transmission of the soft-pack battery pack, improving the flexibility of the equipment, and ensuring the smooth progress of the production process. The conveying sprocket and the conveying chain 10032 are each provided with two, which are respectively installed at the two ends of the transmission shaft 10031 inside the transmission frame 10039, which aims to enhance the carrying capacity of the distributing member 1003 and ensure the stability of the soft-pack battery pack after moving to the vertical position of the station. A push-up cylinder 10035 connected to the fixed frame 1001 is arranged between the two transmission chains, which is driven to rotate by the cam divider 10038 arranged on the fixed frame 1001. The extension end of the push-up cylinder 10035 is fixedly installed with a lifting disc 10033, and the edge of the lifting disc 10033 corresponds to the measuring instrument 10036 arranged on the fixed frame 1001, which is an infrared sensor. When the infrared ray emitted by the measuring instrument 10036 is blocked by the first clamping tray 19 holding the battery pack, the two conveying chains 10032 will stop running, and then the push-up cylinder 10035 will push the lifting disc 10033 to drive the first clamping tray 19 and the battery pack to move up to the corresponding height position. The fixed frame 1001 is provided with a pressure wheel 10034 corresponding to the two sides of the lifting disc 10033 in the direction of rotation of the conveying chain 10032, which is pushed by the auxiliary cylinder arranged on the fixed frame 1001. When the first clamping tray 19 is pushed to the appropriate height and the angle is adjusted by the cam divider 10038, the two pressure wheels 10034 will clamp and position the first clamping tray 19, thereby further ensuring the stability of the tab welding member 1005 during the welding of the tabs. The fixed frame 1001 is also provided with a limiting block 10037 driven by a limiting cylinder to move vertically, which can prevent the position from changing due to the vibration of the push-up cylinder 10035 during the upward and downward movement or angle change of the first clamping tray 19.This is intended to reduce the possibility of positional change between the first clamping tray 19 and the auxiliary welding member 1002 and the guide welding member 1006 after the transition angle of the push-up cylinder 10035, that is, to reduce the time of repeated calibration of the auxiliary welding member 1002 and the guide welding member 1006 with the tab to ensure the efficiency of the tab welding process. When the first clamping tray 19 needs to be input or output, the restriction cylinder allows the restriction block 10037 to move downward, so that the first clamping tray 19 can stably pass to achieve input or output.

[0102] As Figure 22As shown, the auxiliary welding member 1002 includes an auxiliary welding frame 10021 and a longitudinal frame 10022 arranged on the fixed frame 1001. The auxiliary welding frame 10021 is fixedly installed with a push-up cylinder 10035 at the center, the push-up cylinder 10035 is driven with a push plate 10026, the four corners of the push plate 10026 are all arranged with telescopic rods 10027, the telescopic ends of the four telescopic rods 10027 are all fixedly connected with push plates 10029, and the periphery of the telescopic rod 10027 is surrounded by damping springs 10028 arranged between the push plate 10029 and the push plate 10026. After the soft-pack battery pack is pushed to the appropriate height by the push-up cylinder 10035, the auxiliary cylinder 10025 will drive the push plate 10029 and the push plate 10026 to press the top of the battery pack after the angle adjustment of the soft-pack battery pack is completed, so as to further stabilize the position of the soft-pack battery pack, that is, to maintain the position stability of the tab during the processing process. During the process that the push plate 10029 presses the soft-pack battery pack, the damping spring 10028 will reduce the vibration generated when the auxiliary cylinder 10025 is elongated to press the soft-pack battery pack, thereby reducing the position change of the soft-pack battery pack caused by the vibration. The longitudinal frame 10022 drives the transverse frame 10023 to displace along the longitudinal direction, and the transverse frame 10023 drives the guide welding member 1006 to displace transversely, so as to adjust the position of the guide welding member 1006 to correspond to the tab. The guide welding member 1006 includes a guide welding frame 10061 driven by the transverse frame 10023 to displace transversely, the bottom of the guide welding frame 10061 is provided with an adjustment platform 10062, and the adjustment platform 10062 is arranged with four detectors 10063, the four detectors 10063 are inclinedly distributed, so that the laser lines thereof can cross and intersect through the small mouths of the two tab welding nozzles 10065 arranged on the guide welding frame 10061, so as to correspond to the four vertices of the tab of the soft-pack battery pack, that is, to assist in determining the welding position of the tab of the soft-pack battery pack. After the laser is reflected at the four vertices of the tab of the soft-pack battery pack, it again crosses the welding port of the tab welding nozzle 10065 and is detected by the detector 10063. This process not only realizes accurate measurement and verification of the position of the tab, but also improves the reliability and stability of the measurement. During the detection process, the corresponding electric control system will be matched to control the operation of the longitudinal frame 10022 and the transverse frame 10023, so as to ensure that the tab of the soft-pack battery pack corresponds to the tab welding nozzle 10065 accurately. After the position detection is completed, the adjustment platform 10062 will drive the corresponding detector 10063 to give way, so that the tab welding nozzle 10065 cooperates with the tab welding member 1005 to weld the tab. The longitudinal frame 10022, the transverse frame 10023 and the auxiliary cylinder 10024 arranged on the auxiliary welding frame 10021 are all arranged in two, and are arranged in sequence along the width direction of the fixed frame 1001, thereby improving the efficiency of tab welding.The fourth bearing frame 10051 provided on the fixed frame 1001 is provided with a variable distance row frame 10052, the variable distance row frame 10052 drives the auxiliary row frame 10053 to be close to the tab welding nozzle 10065, the auxiliary row frame 10053 drives the positioning frame 10054 to displace along the width direction of the fixed frame 1001. The end of the positioning frame 10054 towards the tab welding nozzle 10065 is fixedly provided with a laser welding piece 10055 and an infrared sensor aligned with the tab welding nozzle 10065. When the laser emitted by the infrared sensor passes through the sidewall of the tab welding nozzle 10065, it indicates that the preliminary movement is in place. After the laser emitted by the infrared sensor passes through the hollow structure of the tab welding nozzle 10065, the parameter position of the laser welding piece 10055 can be stably corresponded with the tab welding nozzle 10065. Then the welding laser emitted by the laser welding piece 10055 can pass through the tab welding nozzle 10065 to weld the tab. The control adjustment after parameter correction can also be realized through a numerical control system. The specific device model and working principle used to correspond the laser welding piece 10055 with the tab welding nozzle 10065 should be understood as prior art. During the welding process, the pipeline connected with the tab welding nozzle 10065 sprays protective gas and absorbs harmful gas after welding, thereby ensuring the welding quality of the tab. In addition, the setting of the auxiliary row frame 10053 enables two groups of tab welding nozzles 10065 to alternately perform welding work, thereby further improving the efficiency of welding tabs. One of the two tab welding nozzles 10065 is connected with the guide welding frame 10061 through the adjusting assembly 10064, and the other is fixedly arranged on the guide welding frame 10061, thereby facilitating the operator to adjust the distance between the two tab welding nozzles 10065 to adapt to the use of tabs of different sizes. The adjusting assembly 10064 includes an auxiliary motor arranged on the guide welding frame 10061, the auxiliary motor drives an adjusting screw rotatably arranged on the guide welding frame 10061, and the auxiliary motor is a reversible stepper motor. When the auxiliary motor is reversely rotated, the tab welding nozzle 10065 slidingly arranged on the guide welding frame 10061 can be driven to displace through the adjusting screw cooperating with the threaded block connected with the tab welding nozzle 10065, so as to adjust the distance between the two tab welding nozzles 10065.

[0103] As Figure 20As shown, the fixing frame 1001 is provided with a fireproof assembly 1004 at a position corresponding to the laser welding piece 10055. The fireproof assembly 1004 includes a monitoring piece 10043 provided on the auxiliary fixing frame 10024 and a guide frame 10041 provided on the transmission frame 10039 towards the laser welding piece 10055. The monitoring piece 10043 is an image monitoring device, which can also be a smoke alarm device. When the soft pack battery pack is on fire during the welding process, the monitoring piece 10043 will send a signal to control the reverse rotation of the conveying chain 10032, so as to convey the soft pack battery pack on fire to the guide frame 10041. Then, the guide frame 10041 guides the soft pack battery pack into the fire extinguishing box 10042, and the water or fire-retardant foam provided in the fire extinguishing box 10042 will extinguish the soft pack battery pack. It is particularly worth noting that a plurality of balls can be arranged on the slope of the guide frame 10041 to reduce the friction between the soft pack battery pack and the slope of the guide frame 10041, thereby increasing the speed of the soft pack battery pack being sent into the fire extinguishing box 10042 after passing through the guide frame 10041, that is, shortening the time of the soft pack battery pack threatening the equipment outside.

[0104] As shown in Figure 23 and Figure 24 , the measuring assembly 11 includes a rack 1101 carrying the conveying piece 6, and a first detection mechanism 1102 and a second detection mechanism are sequentially arranged along the transmission direction of the soft pack battery pack.

As shown in Figure 23 , the processed soft pack battery pack enters the measuring assembly 11 from front to back, and the conveying piece 6 drives the soft pack battery pack to sequentially pass through the first detection station and the second detection station, so that the first detection mechanism 1102 performs post-welding detection of the tab, and the second detection mechanism performs differential pressure detection and DCIR detection, thereby improving the consistency and reliability of the soft pack battery pack product.

[0105] In the present embodiment, during the processing of the soft package battery pack, a plurality of battery packs need to be placed in order and reliably clamped by the first clamping tray 19, and then the tabs are welded, at the same time, the tabs of the battery pack are connected to the busbar to form two electrodes of the soft package battery pack, i.e. the positive electrode and the negative electrode. The first detection mechanism 1102 includes two image acquisition machines 11021 symmetrically arranged on the rack 1101 and used for acquiring images of the tabs of the soft package battery pack, and the acquired images are transmitted to the control unit, the control unit identifies the received images, and the acquisition area is formed between the two image acquisition machines 11021. The fifth support frame 11023 is fixedly connected on the rack 1101, the fifth support frame 11023 includes two vertical supporting rods located on both sides of the first detection station and a horizontal supporting rod, the ends of the horizontal supporting rod are connected with the ends of the two vertical supporting rods by bolts. The fifth support frame 11023 is provided with a camera board 11022 for mounting the image acquisition machine 11021, the first slide rail is fixedly connected on the fifth support frame 11023, the first slide block is fixed on the camera board 11022, the first slide block slides along the first slide rail and can be fixed, and the extension direction of the first slide rail is parallel to the sliding direction of the soft package battery pack. In the present embodiment, the connection mode of the first slide rail and the fifth support frame 11023 and the connection mode of the first slide block and the camera board 11022 are both bolted connection, and the first slide rail and the first slide block are provided to adjust the position of the image acquisition machine 11021 to adapt to different soft package battery packs, thereby improving the application range of the present application.

[0107] During actual detection, the image collected by the image collector 11021 deviates from the actual image due to the illumination of the lamps in the workshop and the influence of the environment. Therefore, the image collector 11021 is provided with a shadowless board 1103 on the side close to another image collector 11021. The top end of the shadowless board 1103 is fixedly connected with a camera board 11022. Correspondingly, a plurality of fixed holes distributed along the length direction of the camera board 11022 are formed on the camera board 11022. The shadowless board 1103 is connected with the fixed holes through bolts. The fixed holes correspond to different positions according to the required position of the shadowless board 1103, so as to adjust the position of the shadowless board 1103, improve the application range of the present application, and improve the quality of the tab image collected by the image collector 11021. The shadowless board 1103 is provided with a glass area for the image collector 11021 to collect the tab image. Specifically, a square hole is formed on the shadowless board 1103. A glass sheet is fixed in the square hole to form a glass area. The side of the shadowless board 1103 away from the image collector 11021 is provided with a light source distributed around the glass area, so as to improve the quality of the tab image collected by the image collector 11021.

[0108] In the embodiment, a fifth cylinder for lifting the soft-pack battery pack and entering the collection area is arranged below the collection area. A third mounting plate is fixedly connected to the lower surface of the guide rail. The third mounting plate is connected to the guide rail in a bolted manner. The fifth cylinder is fixed to the third mounting plate. A first lifting plate parallel to the third mounting plate is arranged above the third mounting plate. A plurality of first sleeves are fixedly connected to the third mounting plate. In the embodiment, the number of first sleeves is one and they are uniformly distributed on the third mounting plate. A plurality of first guide rods corresponding to the first sleeves are fixedly arranged on the first lifting plate. The top end of the guide rod is fixedly connected to the first lifting plate. The bottom end of the guide rod penetrates through the first sleeve and extends into the third mounting plate below. When the bottom plate enters the first detection station, the piston of the fifth cylinder pushes the first lifting plate to move upward. The first lifting plate pushes the bottom plate to move upward, so that the soft-pack battery pack enters the collection area. The image collector 11021 collects the images of the tabs on both sides of the soft-pack battery pack and transmits them to the control unit for identification and detection.

[0109] In the embodiment, the end of the first guide rod extending into the third mounting plate below is fixedly connected with a first limiting plate, which limits the extreme displacement of the semi-solid battery pack in the vertical direction.

[0110] The second detection mechanism comprises a differential pressure detection piece 1105 for differential pressure detection of the soft package battery pack and a DCIR detection piece 1106 for DCIR detection of the soft package battery pack, and a supporting plate 1104 is fixedly connected to the rack 1101, and the differential pressure detection piece 1105 and the DCIR detection piece 1106 are arranged on the supporting plate 1104. It should be noted that the present application simultaneously performs DCIR detection and differential pressure detection on the soft package battery pack, and the differential pressure detection piece 1105 and the DCIR detection piece 1106 are both existing commercially available products, which will not be described here.

[0111] The differential pressure detection piece 1105 comprises two groups of oppositely arranged differential pressure detection units, and each differential pressure detection unit comprises a plurality of detection rods 11051 corresponding to the lug on one side of the soft package battery pack, one end of the detection rod 11051 being capable of contacting the corresponding lug, and the other end of the detection rod 11051 being electrically connected to the corresponding differential pressure detection device, so that the differential pressure detection device detects the voltage of each battery pack when the end of the detection rod 11051 contacts the corresponding lug. The detection rods 11051 of each differential pressure detection unit are divided into two groups, and the detection rods 11051 in each group are distributed at intervals along the extension direction of the guide rail, so that each lug is contacted by a detection rod 11051. The differential pressure detection unit further comprises a first sliding plate 11053 slidingly arranged on the supporting plate 1104, and the first sliding plate 11053 is driven by a multi-purpose cylinder 11052, and the detection rods 11051 of the differential pressure detection unit are fixedly installed on the first sliding plate 11053. Specifically, the first sliding plate 11053 of the right differential pressure detection unit is fixedly arranged at the middle upper position of the supporting plate 1104, the multi-purpose cylinder 11052 of the differential pressure detection unit is bolted to the first fixed plate, the first sliding plate 11053 is fixedly connected to the piston extension end of the multi-purpose cylinder 11052, that is, the first sliding plate 11053 is a vertical plate, the bottom of the first sliding plate 11053 is fixedly connected to a connecting plate, a plurality of connecting rods distributed along the extension direction of the guide rail are fixedly connected to the connecting plate, the detection rods 11051 are fixed to the connecting rods, and each connecting rod has two detection rods 11051. When the right differential pressure detection unit contacts the lug on the right side of the soft package battery pack, the multi-purpose cylinder 11052 drives the first sliding plate 11053 to slide towards the soft package battery pack, thereby driving the detection rods 11051 to slide towards the soft package battery pack until the detection rods 11051 contact the corresponding lug, and the differential pressure detection device measures the voltage of each battery pack; after detection, the multi-purpose cylinder 11052 drives the first sliding plate 11053 to slide away from the soft package battery pack, thereby driving the detection rods 11051 to separate from the corresponding lug, and the detected soft package battery pack enters the next processing procedure.

[0112] The specific structure of the left differential pressure detection unit is that the first fixed plate of the left differential pressure detection unit is fixed at the top end of the supporting plate 1104, a sliding seat connected with the multi-purpose cylinder 11052 is arranged on the first fixed plate in a sliding mode, the first sliding plate 11053 is connected with the sliding seat in a sliding mode and moves up and down by driving the first sliding plate 11053 by the sixth cylinder, the bottom of the first sliding plate 11053 is fixedly connected with another connecting plate, a plurality of connecting rods distributed along the extension direction of the guide rail are fixedly connected to the other connecting plate, the detection rods 11051 are fixed to the connecting rods, and two detection rods 11051 are arranged on one connecting rod. When the left differential pressure detection unit contacts the left tab of the soft package battery pack, the sixth cylinder drives the second sliding plate to slide downward to the required position, at the same time, the multi-purpose cylinder 11052 drives the sliding seat to slide towards the soft package battery pack, thereby driving the second sliding plate to slide towards the soft package battery pack until the detection rods 11051 are in contact with the corresponding tabs on the left side of the soft package battery pack. When the two detection rods 11051 are in contact with the tabs on the two sides of the soft package battery pack, the detection is performed, and after the detection is completed, the multi-purpose cylinder 11052 drives the sliding seat to slide away from the soft package battery pack, so that the detection rods 11051 are separated from the corresponding tabs.

[0113] The DCIR detection piece 1106 includes two groups of DCIR detection pieces 1106 corresponding to the two electrodes of the soft package battery pack, i.e. the positive electrode and the negative electrode. The DCIR detection piece 1106 includes a detection head for connecting with the positive electrode or the negative electrode of the soft package battery pack. The two detection heads are electrically connected with the DCIR detection device. After the detection head contacts the corresponding electrode, the DCIR detection device detects the DCIR of the soft package battery pack. The DCIR detection piece 1106 further includes a second fixed plate 11061 for mounting the detection head. The second fixed plate 11061 is driven by the measuring cylinder 11604 to move up and down, and the detection head can be connected with or separated from the positive electrode or the negative electrode of the soft package battery pack when the second fixed plate 11061 moves up and down. The third fixed plate is fixedly connected in parallel below the second fixed plate 11061. The detection head is fixed to the third fixed plate, and the top end of the detection head is located between the third fixed plate and the second fixed plate 11061 for electrical connection with the transmission line. The bottom end of the detection head penetrates through the second fixed plate 11061 and is located below the second fixed plate 11061 for contacting the electrode of the soft package battery pack.

[0114] In order to avoid that the detection head crushes the soft package battery group electrode, the upper side of the second fixed plate 11061 is provided with an auxiliary connecting plate 11062 which is fixedly connected with the piston of the measuring cylinder 11604, and a plurality of measuring springs 11603 are arranged between the auxiliary connecting plate 11062 and the second fixed plate 11061, one end of the measuring spring 11603 is fixedly connected with the auxiliary connecting plate 11062, and the other end of the measuring spring 11603 is connected with the second fixed plate 11061. Specifically, the two ends of the second fixed plate 11061 are fixedly connected with two vertical slide rods 14013, the auxiliary connecting plate 11062 is provided with a sliding hole, the top end of the slide rod 14013 extends into the sliding hole and the slide rod 14013 can slide along the sliding hole, the measuring spring 11603 is sleeved on the part of the slide rod 14013 between the second fixed plate 11061 and the auxiliary connecting plate 11062, after the soft package battery group is located at the detection position, the auxiliary connecting plate 11062 is driven to move downward by the measuring cylinder 11604, thereby driving the second fixed plate 11061 and the detection head to move downward; after the bottom end of the detection head contacts with the electrode of the soft package battery group, the measuring cylinder 11604 continues to move downward, at this time, the measuring spring 11603 is compressed, and the restoring force of the measuring spring 11603 pushes the detection head to tightly contact with the electrode of the soft package battery group, which improves the detection accuracy, and avoids that the detection head cannot be moved to the position for detection or is moved to the position for damaging the electrode.

[0115] In the embodiment, the first slide plate 11053 is fixedly connected with a supporting plate, when the first slide plate 11053 moves to the position that the detection rod 11051 contacts with the corresponding lug, the supporting plate is located below the electrode of the soft package battery group and contacts with the lower surface of the electrode, which plays a role of bearing the electrode, avoids that the electrode is damaged due to the excessive pressure of the detection head, and plays a role of protecting the electrode.

[0116] The driving cylinder installed on the rack 1101 is arranged between the two DCIR detection pieces 1106, and the top plate is arranged above the driving cylinder. In the embodiment, the fourth mounting plate is fixedly connected below the guide rail of the rack 1101, and the driving cylinder is fixedly installed on the fourth mounting plate. The top plate is above the fourth mounting plate and perpendicular to the piston axis of the driving cylinder. The second sleeve is fixedly connected to the fourth mounting plate, and the second guide rod is slidably arranged in the second sleeve. The top end of the second guide rod extends out of the second sleeve and is fixedly connected to the top plate. The driving cylinder pushes the top plate to move upward, and in turn drives the soft package battery pack above it to move upward. In the embodiment, the bottom end of the second guide rod extends out of the second sleeve and is fixedly connected to the limiting plate, which is used to limit the limit displacement of the soft package battery pack. When the soft package battery pack moves to the second detection station, the driving cylinder pushes the top plate to rise, and in turn drives the soft package battery pack to rise to the detection position. The differential pressure detection piece 1105 and the DCIR detection piece 1106 detect the soft package battery pack. After the detection is completed, the driving cylinder piston retracts, and the soft package battery pack descends to the initial position and is transmitted to the next processing station for processing by the conveying piece 6.

[0117] During the differential pressure detection and DCIR detection of the soft package battery pack, sparks are easily generated at the contact position between the detection rod 11051 and the tab. Therefore, a plurality of push-away cylinders for pushing the soft package battery pack away from the top plate are arranged on the top plate, and a plurality of rollers are rotatably arranged on the top plate. The axis of the roller is parallel to the extension direction of the guide rail. In the embodiment, the number of push-away cylinders is two. A water tank is arranged on one side of the rack 1101, and a measuring cylinder 11604 for pushing the soft package battery pack away from the top plate into the water tank is arranged on the other side of the rack 1101. When sparks appear on the soft package battery pack, the measuring cylinder 11604 drives the detection head to move upward, and the multi-purpose cylinder 11052 on the left side of the soft package battery pack drives the first sliding plate 11053 to make room for the soft package battery pack. At the same time, the sixth cylinder drives the second sliding plate to move upward to avoid the soft package battery pack, so that it can smoothly enter the water tank. Then, the push-away cylinder lifts the soft package battery pack, and the multi-purpose cylinder 11052 on the right side of the soft package battery pack pushes the soft package battery pack into the water tank, thereby improving the safety of the detection equipment.

[0118] In the application, the positioning scanner is arranged in front of the first detection station, and the scanning code is arranged on the bottom plate, which is used for positioning the soft package battery pack on the guide rail. Meanwhile, the positioning assembly 1107 is arranged on the guide rail in the extension direction of the guide rail. The positioning assembly 1107 comprises a positioning cylinder fixedly installed on the guide rail. The fixed seat is fixedly connected below the guide rail. The positioning cylinder is fixedly installed on the fixed seat. The base is fixedly connected to the top end of the piston of the positioning cylinder. The first swing wheel 11071 and the second swing wheel 11073 are rotatably arranged on the base. The vertical plate 11072 is arranged on the first swing wheel 11071. The vertical plate 11072 is fixedly connected with the outer side wall of the first swing wheel 11071. The horizontal plate 11074 is arranged on the second swing wheel 11073. The horizontal plate 11074 is fixedly connected with the outer side wall of the second swing wheel 11073. The accommodating groove for accommodating the vertical plate 11072 is arranged on the bottom plate. When the soft package battery pack is conveyed, the positioning assembly 1107 is located below the bottom plate, so as to ensure the smooth passing of the soft package battery pack. When the positioning scanner scans the bottom plate into the first detection station, the transport part 6 is paused. The base is pushed upward by the positioning cylinder. The vertical plate 11072 enters the accommodating groove, and the horizontal plate 11074 contacts with the lower surface of the bottom plate. At this time, the driving cylinder and the fifth cylinder lift the corresponding soft package battery pack into the detection position. In the application, when the bottom plate is dislocated due to inertia, the vertical plate 11072 will be deflected into the accommodating groove during the lifting of the base. With the vertical plate 11072 entering the accommodating groove, the first swing wheel 11071 will push the bottom plate to correct the position, so as to ensure the accuracy of detection.

[0119] As Figure 1 and Figure 3 shown, in order to improve the quality of the tab welding, the sampling station 12 corresponding to the transmission assembly is arranged between the upper shell assembly 13 and the measurement assembly 11, so as to sample the battery pack after tab welding or to install parts.

The upper shell base 1301 is provided with a recycling station 1304 at the first opening and closing assembly 1302, so as to facilitate the operator to collect and reuse the unused first clamping tray 19. The upper shell base 1301 is provided with a feeding member 1306 at the second opening and closing assembly 1305, so as to place the shell bottom into the second clamping tray 20, and is provided with a tray changing member 1303 to grab the battery pack after the tab welding in the first clamping tray 19, and place it into the second clamping tray 20.

Then, another feeding member 1306 can be used to place the shell top on the top of the stacked battery pack and interface with the shell bottom. In this way, the feeding operation of the battery pack shell is completed.

As shown, Figure 27As shown, the feeding member 1306 includes a feeding seat 13061 provided on the upper shell base 1301, and three row frame seats 13062 are uniformly arranged on the feeding seat 13061. Three shell taking frames 13063 are arranged on the three row frame seats 13062, respectively. The three shell taking frames 13063 are respectively driven by a claw shell cylinder 13064, a glue applying head 13066 and a shell taking cylinder 13068. An identification head 13067 for detecting the glue applying quality of the glue applying head 13066 is arranged on the shell taking frame 13063 between the glue applying head 13066 and the shell taking cylinder 13068. The identification head 13067 can take images and transmit the images to a control unit for processing to determine whether the glue applying is qualified. The claw shell cylinder 13064 can drive the corresponding shell taking frame 13063 to correspond to the shell storage frame 13065 arranged on the upper shell base 1301. Specifically, the shell storage frame 13065 is composed of limiting strips arranged at the four corners of the shell bottom to take the shell placed in the shell storage frame and place the shell bottom on the carrying member to transmit the shell to the glue applying head 13066 so that the glue applying head 13066 applies glue on the shell bottom under the driving of the corresponding shell taking frame 13063. The carrying member can finally transmit the shell bottom with the applied glue to the shell taking cylinder 13068, so that the shell taking cylinder 13068 places the shell bottom in the opened second clamping tray 20, and the glue can stably connect the stacked battery pack and the shell bottom which is transferred by the first clamping claw 13031.

In this embodiment, the first mounting seat 1406 is fixedly provided with a positioning image machine 1407 for shooting the soft package battery pack. When the soft package battery pack moves to the working position of the first welding assembly 14, the positioning image machine 1407 collects the image of the soft package battery pack, and the initial welding position and the stroke of the first laser 14010 are determined through image recognition.

[0124] The first welding assembly 14 includes a first welding bed 1401 for carrying and transporting the second clamping tray 20, and the first welding bed 1401 is provided with two oppositely arranged welding frames 1402, which are arranged on both sides of the conveying member 6.

[0134] As shown in Figure 31 The second welding assembly 16 is used for welding the connection between the bottom plate and the two long edges of the bending part and the connection between the bottom plate and the side plate of the shell. The second welding assembly 16 includes two oppositely arranged second lasers and two welding mechanical arms for driving the corresponding second lasers, which are not shown in the figure. The two welding mechanical arms are located on both sides of the machine tool, and one welding mechanical arm is connected with one second laser. It should be noted that the welding mechanical arm is a commercially available product, which is not shown in the figure, and the model of the welding mechanical arm is FANUC M-iD or FANUC M-iD / and the like. In the embodiment, the second laser and the welding mechanical arm are fixedly connected through a second mounting seat, the second mounting seat is fixedly connected with a corresponding flange 14012 for connecting with the welding mechanical arm, and the second laser is fixedly installed on the second mounting seat. A positioning image machine 1407 for shooting the soft-pack battery pack is fixedly arranged on the second mounting seat. When the soft-pack battery pack moves to the work station of the second welding assembly 16, the positioning image machine 1407 collects the image of the soft-pack battery pack, and the initial welding position and the stroke of the second laser are determined through image recognition.

[0135] The second welding assembly 16 includes a second welding bed 1601 for carrying the conveying member 6. The second welding bed 1601 is provided with two long edge welding frames 1602. The top of each long edge welding frame 1602 is provided with a distance adjusting cylinder 1603. The distance adjusting cylinder 1603 can drive a displacement support 1607 slidingly arranged on the long edge welding frame 1602.

[0136] The second welding bed 1601 is provided with the same structure as the welding frame 1402 arranged on the first welding bed 1401, that is, when the long edge welding nozzle 1605 corresponds to the long edge of the shell bottom, the top edge welding nozzle 14014 designed on the same position of the first welding bed 1401 will correspond to the short edge of the shell bottom, and at the same time, the shell will be pressed to ensure the relative position of the shell during the welding process.

[0137] The second welding assembly 16 is used for welding the soft package battery pack shell. When the conveying member 6 conveys the soft package battery pack to the position of the corresponding welding frame 1402, the corresponding top edge welding nozzle 14014 is matched with the corresponding pressure plate 1409 to correspond to the short edge position of the shell bottom, and the distance adjusting cylinder 1603 is used to drive the displacement support 1607 to displace under the support of the long edge welding frame 1602. Then, the displacement support 1607 drives the two corresponding angle butt cylinders 1606 to the corresponding position through the angle plate 1604, so that the long edge welding nozzle 1605 corresponds to the long edge of the shell bottom. Next, the image positioning machine 1407 collects the image of the soft package battery pack and transmits it to the control unit. The control unit identifies the initial position of the welding through the image recognition and controls the welding mechanical arm to drive the second laser to weld in sequence. After the welding is completed, the long edge welding nozzle 1605 and the short edge welding nozzle are reset.

The detection carrier 1706 is slidingly arranged towards the bottom of the conveying member 6, and a detection carriage 1704 is arranged on the detection carrier 1706. The detection carriage 1704 can be driven by a detection motor to move close to each other to press the two sides of the battery pack. Four detection clamps 1703 are arranged on the detection carriage 1704 and driven by a rotating member. The four detection clamps 1703 are driven to open and close by a control cylinder to clamp or release the four long sides of the battery pack. The rotating member includes a rotating motor arranged on one side of the detection carriage 1704. The rotating motor drives the control cylinder of the detection clamp 1703 to rotate through a transmission belt. An angle detector 10063 is arranged on the outer periphery of the control cylinder to make the control cylinder rotate in a cycle. The detection carrier 1706 is fixedly arranged at the center of the conveying member 6 and provided with a weld observation head 1707. When the rotating member drives the detection cylinder 1705 to rotate the detection clamp 1703 to drive the battery pack to rotate, the weld observation head 1707 can detect the weld of the shell of the battery pack, so as to ensure the ability of the shell to protect the battery pack. During the rotation of the battery pack, the angle detector 10063 can control the rotating motor to rotate at a corresponding angle, so as to improve the quality of the weld observation head 1707 shooting the weld of the shell, that is, to improve the precision of the weld quality detection of the shell. After the detection is completed, the conveying member 6 conveys the processed battery pack to the working range of the offline mechanical arm 18, so that the offline mechanical arm 18 grabs and places the battery pack into the transfer box for subsequent transportation. The conveying member 6 is composed of two chain wheels arranged at intervals to drive two corresponding chains.
