[0025] The present invention provides an embodiment. Refer to Figures 6 - 7, the top encapsulation component 3 includes a first fixing frame 301, on which a first fixing plate 302 and a second fixing plate 315 are fixed.

A second heat sealing member 316 is installed on the upper heat sealing driving component, and a first positioning member 314 is installed on the lower heat sealing driving component. The heat sealing driving component includes a first mounting frame 303, on which a second driving motor 304 is installed. The output shaft of the second driving motor 304 is connected to a first lead screw 305 through a coupling. The first lead screw 305 is connected to a first connecting member 306 through a thread.

[0026] When the folding component 2 and the top encapsulation component are used in combination, it is necessary to first place the aluminum-plastic film and the battery cell that have completed the indentation in the first storage groove 1002 of the storage part 10, and then place the storage part 10 with the aluminum-plastic film and the battery cell that have completed the indentation on the clamping component 211. Before placing, the air cylinder five 21107 at the lower part of the fourth clamping plate 21120 drives the piston five 21108 inside to extend. The piston five 21108 drives the connecting block 21109, the third connecting plate 21110 and the pressing part 21111 to move upward. The pressing part 21111 squeezes the connecting rod 21114, so that the connecting rod 21114 rotates axially with the rotation axis as the axis of rotation, making the end of the first rod body 211141 of the connecting rod 21114 in contact with the pressing part 21111 be pushed upward by the pressing part 21111 to rotate. When the connecting rod 21114 rotates, the second rod body 211143 of the connecting rod 21114 pushes the first swinging part 21112 to move in the direction of the center line of the sliding hole of the third fixing part 21117 as the first rod body 211141 rotates. When the first swinging part 21112 moves, the first swinging part 21112 drives the mounting rod to slide in the sliding hole. The baffle on the mounting rod 21115 squeezes the first spring 21116. The first swinging part 21112 drives the third swinging part 21119 to move, and the third swinging part 21119 drives the fourth clamping plate 21120 to move, so that the distance between the fourth clamping plate 21120 and the second clamping plate 21106 increases;

[0027] Similarly, the air cylinder five 21107 at the lower part of the third clamping plate 21118 drives the piston five 21108 inside to extend. The piston five 21108 drives the connecting block 21109, the third connecting plate 21110 and the pressing part 21111 to move upward. The pressing part 21111 squeezes the connecting rod 21114, so that the connecting rod 21114 rotates axially with the rotation axis as the axis of rotation, making the end of the first rod body 211141 of the connecting rod 21114 in contact with the pressing part 21111 be pushed upward by the pressing part 21111 to rotate. When the connecting rod 21114 rotates, the second rod body 211143 of the connecting rod 21114 pushes the first swinging part 21112 to move in the direction of the center line of the sliding hole of the third fixing part 21117 as the first rod body 211141 rotates. When the first swinging part 21112 moves, the first swinging part 21112 drives the mounting rod 21115 to slide in the sliding hole. The baffle on the mounting rod 21115 squeezes the first spring 21116. The first swinging part 21112 drives the second swinging part 21113 to move, and the second swinging part 21113 drives the third clamping plate 21118 to move, and the distance between the first clamping plate 21105 and the third clamping plate 21118 increases, facilitating the placement of the storage part 10;

[0028] After placing the container 10 with the aluminum-plastic film and the battery cell having completed the pit formation on the clamping assembly 211, the piston five 21108 is retracted by the cylinder five 21107. Under the action of the spring one 21116 of the mounting rod 21115, the clamping plate three 21118 and the clamping plate four 21120 return to their original positions. When the position of the container 10 placed by the handling assembly one 5 is inaccurate, while the clamping plate three 21118 and the clamping plate four 21120 swing, they can push the container 10 to move on the support plate seven 21104, so that the clamping plates one 21105, two 21106, three 21118, and four 21120 complete the clamping of the container 10. The clamping plates one 21105, two 21106, three 21118, and four 21120 play a clamping role. After the clamping plates one 21105, two 21106, three 21118, and four 21120 complete the clamping of the container, the heat-sealing plate seven of the heat-sealing member five 21121 of the clamping assembly is inserted into the top groove 1004 of the container. After completing the clamping, the piston one in the driving cylinder one 206 extends, and the piston one drives the mounting plate two 207 thereon to move upward. The mounting plate two 207 drives the moving plate one 209 and the folding rotating roller 210 thereon to move upward together. The folding rotating roller 210 drives the aluminum-plastic film to move upward. When the folding rotating roller two moves upward, the cylinder two 208 extends simultaneously to drive the moving plate one 209 and the folding rotating roller 210 to perform a preliminary bending on the aluminum-plastic film. The preliminary bending refers to the part of the aluminum-plastic film close to the clamping plate three 21118. This part is also relatively long and naturally hangs on one side of the clamping plate three 21118 of the clamping assembly 211. By driving the folding rotating roller 210 to rise by the cylinder one 206, the horizontal height of this part of the aluminum-plastic film is made higher than that of the battery cell.Then, the piston 2 in the driving cylinder 208 is extended, so that the folding rotating roller 210 moves closely to the aluminum-plastic film and the battery cell toward the clamping assembly 211, and the folding rotating roller 210 makes an axial rotation on the aluminum-plastic film and the battery cell, and the horizontal height of the folding rotating roller 210 is controlled by the piston 1 in the cylinder 1 206, so that the folding rotating roller 210 moves closely to the aluminum-plastic film and the battery cell toward the clamping assembly 211, and the horizontal height of the folding rotating roller 210 is controlled by the piston 1 in the cylinder 1 206, so that The folding rotating roller 210 moves closely to the aluminum-plastic film and the battery cell toward the clamping assembly 211, so that the lower part of the folding rotating roller 210 contacts the battery cell in the containing part 10, thereby folding the upper aluminum-plastic film to the maximum extent, and folding the upper aluminum-plastic film to the maximum extent, so that the bending part of the aluminum-plastic film is closely to the battery cell, and there is as little gap as possible between the bending part and the battery cell. After the folding is completed, the folding rotating roller 210 is moved a distance away from the clamping assembly 211 by the cylinder 2 208. The distance is less than half of the length of the holding groove 1002, so that the folding rotating roller 210 can also squeeze the upper aluminum-plastic film, and then the slider 203 is driven by the driving motor 202 to move toward the top packaging component 3 on the moving slide rail 1, so that the holding part 10 and the top of the aluminum-plastic film battery cell are inserted between the positioning part 1 314 and the heat-sealing part 2 316 of the top packaging component 3, and the positioning part 1 314 and the heat-sealing part 2 316 are driven by the heat-sealing driving component of the top packaging component 3. The two heat sealing members 316 and 317 move towards each other, so that the positioning block 31402 on the positioning member 1 314 is inserted into the positioning groove 211034 at the bottom of the support plate 6 21103 of the clamping assembly 211, and then the heat sealing member 2 316 contacts the heat sealing member 5 21121 on the clamping assembly 211, and the heat sealing plate 6 31602 on the heat sealing member 2 316 and the heat sealing plate 7 on the heat sealing member 5 21121 start to be heated, and the heat sealing of the aluminum-plastic film is completed through the heating and extrusion of the heat sealing plate 6 31602 and the heat sealing plate 7. After the heat sealing is completed, the heat sealing driving component of the top packaging component 3 controls the positioning member 1 314 and the heat sealing member 2 316 to move in the opposite direction, so that the positioning member 1 314 and the heat sealing member 2 316 are away from the clamping component, and then the folding rotating roller 210 is retracted. When retracting, the piston 1 in the control cylinder 1 206 is first extended, so that the folding rotating roller 210 no longer squeezes the aluminum-plastic film and the battery cell, and then the cylinder 2 208 is controlled to be retracted, so that the folding rotating roller 210 leaves the range of the clamping component 211 (the vertical projection of the clamping component 211), and then the cylinder 1 206 is controlled to be completely retracted, and the slider 1 203 is driven by the driving motor 1 202 to move on the moving slide rail 1 in the direction away from the top packaging component 3. There are at least four suction cups on the transport plate, and the transport plate is a rectangular plate. The transport plate is fixed on the moving member of the transport component 1 5. The moving member is installed on the longitudinal moving component 1, and the moving member can be longitudinally displaced on the longitudinal moving member 1. The longitudinal moving component 1 is installed on the transverse moving component 1, and the longitudinal moving component 1 can be transversely displaced on the transverse moving component 1.Moreover, the positions where the four suction cups are arranged correspond to the four corners of the side plates of the container. The handling component 1 drives the handling plate to move to directly above the container, and the suction cups on the handling plate suck the four corners of the container. At the same time, the handling component 1 moves upward to lift the container 10 and the semi-finished soft-pack batteries on it together. Then, the handling component 1 moves horizontally to transport the container 10 to directly above the storage tray 429 of the side encapsulation component 4. Then, the handling component 1 moves downward to place the container 10 and the semi-finished soft-pack batteries on it together in the storage tray 429, and the suction cups release the suction on the container 10, thus completing the handling.

[0033] When the side packaging assembly works, by turning on the driving motor four 431 to drive the lead screw three 432 to rotate, the connecting member three on the lead screw three drives the moving plate four 424 to move on the fixed slide rail four 422, driving the holding member 10 containing the soft-pack battery that has completed the top packaging to move towards the side packaging assembly 4. When the moving plate four 424 moves to the end of the lead screw three 432, when the connecting member three on the lead screw three moves to the end of the lead screw three 432 (in contact with the bearing member four 434), the moving plate four 424 moves to the directly below the two third heat-sealing members 405. The positions of the first heat-sealing plates 40504 of the two third heat-sealing members 405 correspond to the positions of the side grooves 1005 of the holding member 10 on the moving plate four 424, and the first heat-sealing plates 40504 can be inserted into the side grooves 1005.

[0034] Then, the second lead screw 413 is rotated by the driving motor three 411, so as to drive the connection piece two on the second lead screw 413 to move downward. The connection piece two 414 moves downward through the connection cylinder 415 and the fifth support plate 419. When the fifth support plate 419 moves downward, it drives the heat-sealing piece four 420 to also move downward. First, the lower end surface of the extrusion block 42003 on the heat-sealing piece four 420 comes into contact with the upper end surface of the side plate 1003 of the placing piece 10 on the feeding assembly. The heat-sealing piece four 420 continues to move downward, and the extrusion block 42003 pushes the placing piece 10 and the placing tray 429 downward. When the placing tray 429 moves downward, the second telescopic rod 428 moves in the second telescopic cylinder 427, and the spring two in the second telescopic cylinder 427 is compressed. When the placing tray 429 and the placing piece 10 move downward, the first heat-sealing plate 40504 on the heat-sealing piece three 405 is inserted into the side groove 1005 of the placing piece 10. When the lower end surface of the side plate 1003 of the placing piece 10 comes into contact with the upper end surface of a trapezoidal reinforcing piece one 40505, the first heat-sealing plate 40504 of the heat-sealing piece three 405 comes into contact with the second heat-sealing plate 42002 of the heat-sealing piece four 420. At the same time, the lower end surface of the support block 1006 of the placing piece 10 comes into contact with the upper end surface of the trapezoidal reinforcing piece two 40506. The limit is completed through the trapezoidal reinforcing piece one 40505 and the side plate 1003, and the trapezoidal reinforcing piece two 40506 and the support block 1006 also complete the limit for the side sealing. The first heat-sealing plate 40504 of the heat-sealing piece three 405 and the second heat-sealing plate 42002 of the heat-sealing piece four 420 start to heat up. Through the heating and extrusion of the first heat-sealing plate 40504 and the second heat-sealing plate 42002, the heat-sealing of the side part of the aluminum-plastic film is completed.

[0035] After the side packaging is completed, the driving motor three 411 drives the lead screw two 413 to rotate in the reverse direction, thereby driving the connection two on the lead screw two 413 to move upward. The connecting piece two 414 moves upward through the connecting cylinder 415 and the support plate five 419. When the support plate five 419 moves downward, it drives the heat sealing piece four 420 to also move upward. Without the extrusion of the extrusion block on the feeding component, the spring two on the feeding component pushes up the holding tray, causing the heat sealing plate one 40504 on the heat sealing piece three 405 to be withdrawn from the side groove 1005 of the holding piece 10. Then, the driving motor four 431 drives the lead screw three 432 to rotate in the reverse direction, causing the holding piece 10 filled with the completed packaged product to move away from the side packaging component 4; during the movement, the handling component two 6 drives the insertion plate to move horizontally, causing the insertion plate to move to directly above the holding piece to be handled. Then, the insertion plate of the handling component two moves downward, so that the insertion plate and the slot of the holding piece are at the same horizontal height. Then, the driving motor four 431 drives the lead screw three 432 to rotate in the reverse direction, causing the holding piece 10 filled with the completed packaged product to move away from the side packaging component 4, so that the insertion plate is inserted into the slot of the holding piece. Then, the handling component two 6 moves upward together with the holding piece, causing the holding piece to leave the holding tray 429 of the feeding component. Then, the handling component two 6 moves horizontally, causing the holding piece 10 to move to directly above the holding tray 429 of the detection component. Then, the handling component two 6 drives the holding piece 10 to move downward, thereby placing the holding piece 10 on the holding tray of the detection component 7. After the detection component 7 finishes the detection, the handling component two 6 places the holding piece 10 in the edge trimming component one 8 and the edge trimming component two 9 to trim the soft package battery. The handling component two 6 can simultaneously handle the holding pieces 10 on the side packaging component 4, the detection component 7, and the edge trimming component one 8. The handling component two 6 includes a transverse movement component two, and four insertion plates are provided on the transverse movement component two. The insertion plates can move horizontally on the transverse movement component two, and all the insertion plates are linked on the transverse movement component two, that is, the insertion plates move horizontally on the transverse movement component two, and the distance between adjacent two insertion plates remains unchanged. The detection component 7, the edge trimming component one 8, and the edge trimming component two 9 are each equipped with a feeding component, and a holding tray 429 is provided on each feeding component. That is to say, a holding tray 429 is provided on each of the side packaging component 4, the detection component 7, the edge trimming component one 8, and the edge trimming component two 9. The distance between adjacent two insertion plates on the transverse movement component two is equal to the distance between adjacent two holding trays 429. The transverse movement component two is arranged on the longitudinal movement component two, and the transverse movement component two can move longitudinally on the longitudinal movement component two.

[0036] The processes on the side encapsulation component 4, the detection component 7, the first trimming component 8, and the second trimming component 9 can be carried out simultaneously. After the processes are completed, they are uniformly transported by the second handling component 6. That is to say, a holding member 10 is installed on the storage tray 429 of the feeding component below the second trimming component 9, and the battery pack trimmed by the first trimming component 8 is placed on the holding member 10; a holding member 10 is installed on the storage tray 429 of the feeding component below the first trimming component 8, and the battery pack after being detected by the detection component 7 is placed on the holding member 10; a holding member 10 is installed on the storage tray 429 of the feeding component below the detection component 7, and the battery pack with side encapsulation completed by the side encapsulation component 4 is placed on the holding member 10; a holding member 10 is installed on the storage tray 429 of the feeding component below the side encapsulation component 4, and the battery pack with top edge encapsulation completed by the top encapsulation component is placed on the holding member 10. The holding member 10 on the storage tray 429 of the feeding component below the side encapsulation component 4 is transported from the clamping component of the top encapsulation component by the first handling component; the insertion plate closest to the side encapsulation component 4 on the second handling component moves above the slot of the storage tray 429 of the side encapsulation component 4 driven by the second lateral movement component. Then the other three insertion plates will also move above the corresponding storage trays 429 of the detection component 7, the first trimming component 8, and the second trimming component 9. Then, the second longitudinal movement component drives the lateral movement component and the insertion plate to move to the corresponding longitudinal height, that is, the lower end surface of the insertion plate is on the same horizontal plane as the lower bottom surface of the slot of the storage tray 429. Then, the driving motor four 431 of the feeding component drives the lead screw three 432 to rotate, so that the holding member 10 moves towards the direction close to the insertion plate, and the insertion plate is inserted into the slot of the holding member 10. Then, driven by the second longitudinal movement component of the second handling component, the lateral movement component two together with the holding member 10 moves upward, so that the holding member 10 leaves the storage tray 429 of the feeding component. Then, the lateral movement component two of the second handling component 6 makes a horizontal movement, so that the holding member 10 originally located on the side encapsulation component 4 moves above the storage tray 429 of the detection component 7, the holding member 10 originally located on the detection component 7 moves above the storage tray 429 of the first trimming component 8, the holding member 10 originally located on the first trimming component 8 moves above the storage tray 429 of the second trimming component 9, and the storage tray 429 originally located on the second trimming component 9 moves above the storage tray 429 of the packaging and palletizing component. Then, the second handling component drives the holding member 10 to move downward through the second longitudinal movement component, so as to place the holding member 10 on the corresponding storage tray 429, thus completing the handling of materials between the side encapsulation component 4, the detection component 7, the first trimming component 8, and the second trimming component 9. Therefore, the processes on the side encapsulation component 4, the detection component 7, the first trimming component 8, and the second trimming component 9 can be carried out simultaneously. After the processes are completed, they are uniformly transported by the second handling component 6.
