DETAILED DESCRIPTION

[0037] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. Parts not described and disclosed in detail in the following embodiments of the present invention should be understood as existing technologies known or should be known to those skilled in the art.

[0038] Example 1

[0039] A tab trimming device for a soft-pack battery includes a feeding device and a tab trimming device. When a cell 90 is processed on the trimming device, adjacent cells 90 need to maintain a fixed distance to avoid contact or interference during the transfer process. Therefore, the feeding device includes a material frame 1 for holding the cell 90 and several adjustment components arranged on a spacing adjustment table 3 and used to adjust the distance between the cells 90, such as Figure 2 As shown, the material frame 1 has four linearly arranged storage areas. The battery cells 90 in each storage area are evenly distributed along the height, enabling simultaneous loading of four battery cells 90. In this embodiment, there are two adjustment assemblies, which are distributed along the width of the battery cells 90. One adjustment assembly can adjust two battery cells 90, and two adjustment assemblies can adjust four battery cells 90 at a time, so that the spacing between two adjacent battery cells 90 in the four battery cells 90 meets the spacing requirements of the battery cells 90 in the tab trimming device.

[0040] The adjustment assembly includes two first carrier plates 91 positioned opposite each other and capable of moving toward or away from each other. The battery cells 90 within the material frame 1 are moved onto the first carrier plates 91 via the transfer assembly. The cells 90, after adjustment, are then transferred from the first carrier plates 91 to the conveyor mechanism via the loading unit 10. The first carrier plates 91 are slidably connected to the adjustment platform 3, which is fixedly connected to two sets of first rails corresponding to the adjustment assemblies. Each set contains two first rails, distributed along the length of the first carrier plates 91. First sliders corresponding to the two first rails are fixedly connected to the first carrier plates 91 and can slide along the rails. A fourth cylinder 8 is provided between the two first support plates 91 to drive the two toward and away from each other. The fourth cylinder 8 is fixedly mounted on the distance adjustment platform 3 and is located below the first support plates 91. The two pistons of the fourth cylinder 8 are fixedly connected to the corresponding first support plates 91. When the two first support plates 91 move toward each other, the distance between them decreases; when the two first support plates 91 move away from each other, the distance between them increases. Anti-deflection blocks are fixedly connected to the two opposing edges of the first support plates 91. The top of the anti-deflection blocks is higher than the upper surface of the first support plates 91, limiting the position of the battery cells 90 on the first support plates 91 and preventing them from deflecting.

[0041] The transfer assembly includes a transfer plate 18 and a second robotic arm for driving the transfer plate 18. The second robotic arm is capable of driving the transfer plate 18 in vertical and rotational motion. The transfer plate 18 is provided with multiple groups of second suction cups 19 for adsorbing the battery cells 90, with each group of second suction cups 19 corresponding to one battery cell 90. In this embodiment, the second suction cups 19 are divided into four groups. The distance between two adjacent groups of second suction cups 19 corresponds to the distance between the battery cells 90 within the material frame 1, so that each group of second suction cups 19 adsorbs one battery cell 90. Each group of second suction cups 19 has four second suction cups 19 and is evenly fixed on both sides of the transfer plate 18. Specifically, two second suction cups 19 in each group are located on one side of the transfer plate 18, and the other two are located on the other side of the transfer plate 18. The second suction cups 19 on the same side are distributed along the length of the transfer plate 18. The second suction cups 19 are fixedly connected to the transfer plate 18 via an "L"-shaped connecting piece, which is connected to the transfer plate 18 by bolts.

[0042] The loading unit 10 includes a second connecting plate 12 that corresponds one-to-one with the first supporting plate 91. The second connecting plate 12 is fixedly provided with multiple third suction cups 13 for adsorbing the battery cells 90. The second connecting plate 12 is capable of horizontal and vertical reciprocating motion. The number of second connecting plates 12 is the same as the number of first supporting plates 91, that is, there are four second connecting plates 12. The spacing between two adjacent second connecting plates 12 matches the spacing between the battery cells 90 in the tab trimming device. Each second connecting plate 12 is provided with four third suction cups 13. The four third suction cups 13 are divided into two parts and are located on either side of the second connecting plate 12. The two third suction cups 13 on each side are fixedly connected to the second connecting plate 12 via a "Z"-shaped connecting piece.

[0043] The second connecting plate 12 is set up in such a way that a first slide cylinder 9 is provided on the distance adjusting platform 3, a first fixed plate is fixedly connected to the slide of the first slide cylinder 9, a first fixed plate is fixedly connected to the first support plate 17, and the second connecting plate 12 is fixed to the first support plate 17, and a reinforcing plate is provided between the first fixed plate and the first support plate 17 to increase the stability of the first fixed plate and the first support plate 17; a first fixed frame is provided on the distance adjusting platform 3, a guide rail extending along the sliding direction of the first support plate 17 is fixedly connected to the first fixed frame, and a guide block is fixedly connected to the end of the first support plate 17 facing away from the first slide cylinder 9, and the guide block can slide along the guide rail. A sixth cylinder 11 is provided on the first support plate 17 for driving the second connecting plate 12 to move vertically back and forth. The number of the sixth cylinders 11 is the same as the number of the second connecting plates 12, and the two correspond one to one, that is, the piston end of the sixth cylinder 11 is fixedly connected to the corresponding second connecting plate 12.

[0044] When the battery cell 90 on the first carrier plate 91 is translated, the first slide cylinder 9 drives the first support plate 17 to slide, thereby driving the third suction cup 13 to be located above the corresponding battery cell 90, and the sixth cylinder 11 drives the third suction cup 13 to move downward until it contacts the battery cell 90 and fixes the battery cell 90; the sixth cylinder 11 drives the third suction cup 13 and the battery cell 90 to rise, and then the first slide cylinder 9 drives the first support plate 17 to slide until the battery cell 90 is located above the conveyor belt 21 of the tab adjustment device, and the third suction cup 13 moves downward to place the battery cell 90 on the conveyor belt 21, and separates from the battery cell 90 to complete the loading.

[0045] A push block 7 for pushing the battery cells 90 on the first supporting plate 91 is provided at one end of the first supporting plate 91 away from the loading unit 10, and an eleventh cylinder 4 for pushing the push block 7 to reciprocate is provided on the distance adjustment platform 3. Specifically, the piston end of the eleventh cylinder 4 is fixedly connected to the first connecting plate 5. The first connecting plate 5 is vertically arranged, the bottom end of the first connecting plate 5 is fixedly connected to the piston end of the eleventh cylinder 4, and the top end of the first connecting plate 5 is connected to the push block 7. A plurality of springs 6 are provided between the first connecting plate 5 and the push block 7, and the number of springs 6 is two; a plurality of connecting rods are slidably provided on the first connecting plate 5, and the number of connecting rods corresponds to the number of springs 6. The connecting rod is a cylindrical structure, and one end of the connecting rod is fixedly connected to a baffle to prevent the connecting rod from falling off the first connecting plate 5. The other end of the connecting rod passes through the first connecting plate 5 and is fixedly connected to the push block 7, and the spring 6 is sleeved on the connecting rod. After adjusting the distance between the first supporting plate 91 and the battery cell 90, the eleventh cylinder 4 pushes the push block 7 toward the battery cell 90 and pushes the edge of the battery cell 90 to adjust the position of the battery cell 90 to ensure that the edge of the battery cell 90 is flush. The setting of the spring 6 plays a buffering role to prevent the push block 7 from damaging the battery cell 90.

[0046] In this embodiment, two first protective claws 14 are provided on each second connecting plate 12. Specifically, a fifth cylinder 92 is fixedly connected to the second connecting plate 12, and the fifth cylinder 92 drives the two first protective claws 14 to move toward or away from each other. The first protective claw 14 includes a fixed rod fixedly connected to the piston end of the fifth cylinder 92, and a stopper 15 is fixedly connected to the lower surface of the fixed rod. A protective part 16 is vertically fixed on the end of the stopper 15 facing away from the fixed rod. When the first protective claws 14 move toward each other, the protective part 16 can enter under the battery cell 90, so that when the third suction cup 13 translates the battery cell 90, it protects the battery cell 90 and prevents it from falling.

[0047] The tab trimming device includes a transmission mechanism arranged on a machine tool 20 and used to transport the battery cell 90. Along the transmission direction of the battery cell 90, there are arranged in sequence an electrode detection mechanism 24 for detecting the tab electrodes of the battery cell 90, an adjustment mechanism 25 for adjusting the direction of the tab electrodes of the battery cell 90, a flipping mechanism 26 for flipping the battery cell 90, a primary flattening mechanism 27 for flattening the tabs, a laser cutting mechanism 28 for cutting the tabs, a secondary flattening mechanism 29 for flattening the tabs, and a size detection mechanism 30 for detecting the tabs.

[0048] The transmission mechanism includes a conveyor belt 21, and the conveyor belt 21 is fixedly provided with a plurality of carrying units distributed along its length direction. The carrying units move synchronously with the conveyor belt 21, and the battery cells 90 are placed on the carrying units, and then the conveyor belt 21 drives the battery cells 90 to move synchronously. The carrying unit includes two symmetrically arranged second carrying plates, and the second carrying plates are fixedly connected to the conveyor belt 21. Specifically, the second carrying plates are connected to the conveyor belt 21 through pads 22, and the pads 22 are fixedly connected to the conveyor belt 21, and the connection method of the two is bolt connection; the second carrying plates are fixedly connected to the pads 22, and the connection method of the two is bolt connection. Limiting members 23 are provided at both ends of each second carrying plate, and the four limiting members 23 enclose an accommodation space for accommodating the battery cells 90. As shown Figure 5 As shown, the left second carrier plate has two stoppers 23. Stoppers 23 are located above and fixedly connected to the second carrier plate via bolts. A first stopper is vertically fixedly connected to the end of the stopper 23 facing away from the other second carrier plate. The first stopper is higher than the upper surface of the battery cell 90. A second stopper is perpendicularly disposed on the edge of the stopper 23 facing away from the end of the same second carrier plate. The second stopper is lower than the upper surface of the battery cell 90. The lower surface of the battery cell 90 is located within the accommodation space enclosed by the four stoppers 23. The lower surface of the tab of the battery cell 90 contacts the end of the second stopper and extends out of the accommodation space.

[0049] The electrode detection mechanism 24 includes a detector 37 and a plurality of detection heads 35 connected to the detector 37. The detection heads 35 can contact the tabs of the battery cell 90. The detector 37 is fixedly mounted on the machine tool 20 via a first support frame 31. The first support frame 31 is provided with a first cylinder 33 for driving the detection heads 35 to contact or separate from the battery cell 90. Figure 6 As shown, the first support frame 31 includes two vertically arranged first vertical rods and a horizontally arranged first horizontal rod. The two first vertical rods are located on both sides of the conveyor belt 21, and the bottom ends of the first vertical rods are fixedly connected to the machine tool 20, and the connection method between the two is bolt connection. The two ends of the first horizontal rod are respectively fixedly connected to the top ends of the two first vertical rods, and the connection method between the two is bolt connection. In this embodiment, the detector 37 is fixedly installed on the first horizontal rod.

[0050] A first cylinder 33 and the detection head 35 pushed by the first cylinder 33 form an electrode detection unit. In this embodiment, there are four electrode detection units, divided equally into two groups. The two groups of electrode detection units are spaced apart along the conveying direction of the battery cells 90. The electrode detection units in each group are located on both sides of the conveyor belt 21. Each group of electrode detection units detects one battery cell 90, that is, it can simultaneously detect the tabs of two battery cells 90. In this embodiment, each electrode detection unit has four detection heads 35.

[0051] The first cylinder 33 is connected to the first support frame 31 in the following manner: a second fixing plate is fixedly connected to each of the first vertical rods of the first support frame 31. The length of the second fixing plate is parallel to the direction of transmission of the battery cells 90, and the second fixing plate is connected to the first support frame 31 by bolts.

Multiple support plates 36 capable of supporting the tabs are fixedly connected to the first mounting plate 32. The support plates 36 are located at the bottom of the first mounting plate 32 and are connected by bolts.

[0052] The working process of the electrode detection mechanism 24 is as follows: the conveyor belt 21 conveys the battery cell 90 to the mechanism's workstation, the pole tab is located between the support plate 36 and the detection head 35, and the lower surface of the pole tab is in contact with the upper surface of the support plate 36; the first cylinder 33 drives the corresponding detection head 35 to move downward until the detection head 35 is in contact with the corresponding pole tab; the detector 37 detects the pole tab, determines the positive and negative poles of the battery cell 90 and transmits it to the control system; after the detection is completed, the first cylinder 33 drives the detection head 35 to rise, separates the detection head 35 from the pole tab, and the conveyor belt 21 conveys the battery cell 90 to the next workstation.

[0053] If the direction of the tab electrode of the battery cell 90 is correct, the adjustment mechanism 25 does not work. If the direction of the tab electrode of the battery cell 90 is wrong, the control system controls the adjustment mechanism 25 to adjust its electrode direction. The adjustment mechanism 25 includes a first suction cup 44 for grabbing the battery cell 90. The first suction cup 44 is vertically reciprocated by a first drive assembly and rotated by a second drive assembly. The first drive assembly includes a second cylinder 40. The second cylinder 40 is mounted on the machine tool 20 through a second support frame 38. The second support frame 38 includes two vertically arranged second vertical rods and a horizontally arranged second horizontal rod. The two second vertical rods are located on both sides of the conveyor belt 21, and the bottom ends of the second vertical rods are fixedly connected to the machine tool 20. The connection method of the two is bolt connection. The two ends of the second horizontal rod are respectively fixedly connected to the top ends of the two second vertical rods. The connection method of the two is bolt connection. The second cylinder 40 is connected to the second support frame 38 in such a way that a second slide cylinder 39 is fixedly mounted at the center of the second horizontal rod. The second cylinder 40 is fixed to the slide of the second slide cylinder 39 and can drive the second cylinder 40 and the first suction cup 44 to move along the conveying direction of the battery cell 90. The second driving assembly includes a first rotary cylinder 41 fixedly mounted on the piston end of the second cylinder 40. The first rotary cylinder 41 is drivingly connected to the first suction cup 44. Specifically, the piston end of the first rotary cylinder 41 is fixedly connected to a first rotating plate 42. Two symmetrically distributed first connecting pieces 43 are fixedly connected to the first rotating plate 42. One end of the first connecting piece 43 is fixedly connected to the first rotating plate 42, and the two are connected by bolts. The other end of the first connecting piece 43 is fixedly mounted on a first suction cup 44, and each first connecting piece 43 is mounted with two first suction cups 44. Two second protective claws 46 are slidingly provided on the first rotating plate 42. The two second protective claws 46 are driven by the seventh cylinder 45 to move toward or away from each other. The seventh cylinder 45 is a double-acting cylinder and is fixedly installed at the center position of the first rotating plate 42 and is located below the first rotating plate 42. The two second protective claws 46 are correspondingly fixed on the pistons on both sides of the seventh cylinder 45; the end of the second protective claw 46 is provided with a bent portion that can be located below the battery cell 90, and when the first suction cup 44 absorbs the battery cell 90 and rotates, the bent portion of the second protective claw 46 is located below the battery cell 90, thereby playing a protective role and preventing the battery cell 90 from falling.

[0054] The working process of the adjustment mechanism 25 is as follows: the electrode detection mechanism 24 detects the electrodes of the battery cell 90. If the electrode direction of the battery cell 90 is opposite, the electrode direction needs to be adjusted through the adjustment mechanism 25.

In this embodiment, the number of clamping units is two and they are distributed along the transmission direction of the battery cell 90. One clamping unit corresponds to one battery cell 90, that is, the flipping mechanism 26 can flip two battery cells 90 at the same time, thereby improving the processing efficiency of the soft-pack battery. The clamping unit includes two clamping jaws 51 that can move toward and away from each other. A clamping area is formed between the two clamping jaws 51, and the two clamping jaws 51 move toward each other so that the edge of the battery cell 90 contacts the clamping jaws 51. The third drive assembly includes a second support plate 47 fixedly connected to the machine tool 20 and a fourth connecting plate 49 slidably connected to the second support plate 47.

Sliders corresponding to the slide rails are fixedly connected to the fourth connecting plate 49, and the slide rails can slide along the slide rails. The fourth connecting plate 49 is driven to reciprocate vertically by the eighth cylinder 48, which is fixedly mounted on the side of the second support plate 47 facing away from the conveyor belt 21.

[0056] The fourth drive assembly includes a second rotary cylinder 50 fixedly mounted on the second support plate 47.

[0059] The working process of the flipping mechanism 26 is as follows: first, the barcode scanning gun 55 scans the battery cell 90 logo. If the barcode scanning gun 55 does not retrieve the battery cell 90 logo, the eighth cylinder 48 drives the clamping jaw 51 to move downward to the required position, and the ninth cylinder 53 drives the two clamping jaws 51 to move toward each other. The two clamping jaws 51 move toward each other so that the edge of the battery cell 90 conflicts with the clamping jaw 51. Specifically, the edge of the battery cell 90 enters the groove and conflicts with the bottom of the groove, thereby fixing the battery cell 90; after the eighth cylinder 48 drives the clamping jaw 51 to move upward to the required position, the second rotating cylinder 50 drives the clamping jaw 51 to rotate 180° so that the battery cell 90 logo faces upward, completing the flipping; the eighth cylinder 48 drives the clamping jaw 51 to move downward until the battery cell 90 is located in the second supporting plate. After the ninth cylinder 53 drives the two clamping jaws 51 to move away from each other, the eighth cylinder 48 drives the clamping jaw 51 to move upward, so that the transmission mechanism transfers the battery cell 90 to the next workstation.
