Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production, and in particular to a packaging device for lithium battery casings. Background Art

[0002] After the casings of lithium batteries are produced and tested, it is necessary to sort, arrange the casings, and package them in a certain quantity before shipping. Due to the huge production capacity of the casings of lithium batteries, it takes a long time to pick and place them individually, and picking and placing multiple ones easily causes adjacent casings to rub against each other, resulting in damage to the outer surface of the casings. If manual operations such as picking and placing the casings, counting the quantity, arranging them, and boxing them are adopted, it will consume a large amount of manpower. The consistency of manual packaging is relatively low, and it may cause secondary collisions of the casings due to improper manual operations, thereby causing damage to the casings. Moreover, the working efficiency of manual packaging is low and cannot meet the production capacity requirements. Summary of the Invention

[0057] Refer to Figures 1 to 10, A lithium battery shell packaging device provided by an embodiment of the present invention includes a paper inserting device 100, a shell feeding device 200, a sorting device 300, a box body feeding device 400, and a boxing device 500:

[0058] Referring to Figure 6 and Figure 7 , the paper inserting device 100 includes a first paper storage mechanism 110, a first paper picking suction nozzle 120, and a paper inserting mechanism 130. The first paper storage mechanism 110 includes a first paper storage bin 111. The first paper picking suction nozzle 120 is located above the first paper storage bin 111, and the paper inserting mechanism 130 is located on the side of the first paper storage bin 111. The first paper storage bin 111 is used to place the stack of separator papers; Referring to Figure 1 , Figure 2 and Figure 5 , the shell feeding device 200 is used to convey the shell 910; Referring to Figures 3 to 5 , the sorting device 300 includes a feeding mechanism 310, a sorting mechanism 320, and a pushing mechanism 330. The feeding mechanism 310 is located at the output end of the shell feeding device 200. The feeding mechanism 310 and the pushing mechanism 330 are arranged in sequence along the first direction. The sorting mechanism 320 includes a first support rod 321, a second support rod 322, a first limiting member 323, and a second limiting member 324 that extend along the first direction. The first support rod 321 and the second support rod 322 are spaced apart in the second direction and are used to support the shell 910 below the shell 910. The first limiting member 323 and the second limiting member 324 are spaced apart in the second direction and are used to limit the shell 910 on both sides of the shell 910. The second direction is perpendicular to the first direction. Referring to Figure 4 , above the first support rod 321 and the second support rod 322, a feeding station 3221 and a pressing station 3222 are defined and arranged in sequence along the first direction. There is a paper inserting gap 3223 between the feeding station 3221 and the pressing station 3222; Referring to Figure 1 , Figure 2 and Figure 8 , the box body feeding device 400 is used to convey the box body 920, and the box body feeding device 400 has a boxing station 410; Referring to Figure 9 , the boxing device 500 includes a carrier plate 510, a clamping mechanism 520, and a moving mechanism 530. The clamping mechanism 520 includes two clamping plates 521. Both clamping plates 521 are connected to the carrier plate 510. The pushing mechanism 330 can convey the shell group 900 to the carrier plate 510. The two clamping plates 521 are used to clamp both sides of the shell group 900. The moving mechanism 530 is connected to the clamping mechanism 520.

[0059] During the operation of the lithium battery case packaging device provided by the embodiment of the present invention, the case feeding device 200 transports the case 910 along the second direction to the loading mechanism 310. The loading mechanism 310 transports the case 910 to the loading station 3221. The first paper picking suction nozzle 120 takes out the topmost separator paper 930 in the separator paper stack in the first paper storage bin 111 and sends the separator paper 930 to the paper inserting mechanism 130. The paper inserting mechanism 130 inserts the separator paper 930 into the paper inserting gap 3223 in the vertical direction (i.e., the direction perpendicular to the first direction and perpendicular to the second direction). The pushing mechanism 330 pushes the case 910 located at the loading station 3221 along the first direction, so that the case 910 located at the loading station 3221 and the separator paper 930 located in the paper inserting gap 3223 both enter the pressing station 3222, and a plurality of cases 910 and a plurality of separator papers 930 form a case group 900 in the pressing station 3222. After the case group 900 has a predetermined number of cases 910, the pushing mechanism 330 pushes the case group 900 along the first direction and outputs it to the carrier plate 510. The clamping mechanism 520 clamps the case group 900 on the carrier plate 510, and the moving mechanism 530 drives the clamping mechanism 520 to move, so that the case group 900 is loaded into the box body 920 located at the box loading station 410.

[0060] A lithium battery case packaging device provided by the embodiment of the present invention can automatically perform steps such as taking the case 910, inserting the separator paper 930 between adjacent cases 910, arranging the cases 910 and the separator papers 930 into a case group 900 with a predetermined number, and loading the case group 900 into a box, realizing the automatic packaging of the case 910 of the lithium battery, which is beneficial to improving the consistency of the case 910 packaging, reducing the secondary collision of the case 910 to reduce the possibility of case 910 damage, and improving the packaging efficiency of the case 910.

[0061] Further, referring to Figure 3 and Figure 4 , it should be noted that, in order to better show the structure of the material arranging device 300, Figure 4 the separator paper 930 is not shown in

[0062] The loading part 311 of the unsupported housing 910 is located at the output end of the housing feeding device 200. When the housing 910 is conveyed to the output end of the housing feeding device 200, the loading lifting driving part 312 drives the loading part 311 to rise, jacking up the housing 910 from the housing feeding device 200. Then, the loading translation slider 313 moves along the loading translation track 314 in the direction of the loading station 3221. It should be noted that during the above process, the bottom of the housing 910 is not lower than the first support rod 321 and the second support rod 322; until the housing 910 reaches the loading station 3221, the loading translation slider 313 stops moving, and the loading lifting driving part 312 drives the loading part 311 to descend. During the descending process, the bottom of the housing 910 first contacts the first support rod 321 and the second support rod 322 and stays at the loading station 3221. The loading part 311 continues to descend until it will not interfere with the housing 910 or other structures, and then the loading translation slider 313 moves along the loading translation track 314 to the output end of the housing feeding device 200 to prepare for the next loading.

[0063] Further, referring to Figure 5 , the housing feeding device 200 includes a first housing conveying mechanism 210 and a second housing conveying mechanism 220 arranged in sequence along the second direction. The second housing conveying mechanism 220 is the output end of the above-mentioned housing feeding device 200. The second housing conveying mechanism 220 includes a plurality of conveying rollers 221 extending along the first direction and arranged in sequence along the second direction. A plurality of loading parts 311 are provided, and the plurality of loading parts 311 and the plurality of conveying rollers 221 are arranged alternately. Thus, on the second housing conveying mechanism 220, the housing 910 can move along the second direction until it reaches the position where the loading parts 311 are located, and then the plurality of loading parts 311 can protrude from the intervals between the plurality of conveying rollers 221 to jack up the housing 910.

[0064] Further, referring to Figure 3 and Figure 4 , the pushing mechanism 330 includes a pushing plate 331, a support plate 332, a pushing lifting driving part 333, a pushing translation slider 334 and a pushing translation track 335. The support plate 332 extends along the first direction. The pushing plate 331 is connected to one end of the support plate 332 close to the loading mechanism 310 and protrudes upward relative to the support plate 332. The output end of the pushing lifting driving part 333 is connected to the combination of the pushing plate 331 and the support plate 332. The pushing lifting driving part 333 is installed on the pushing translation slider 334, and the pushing translation slider 334 is slidably connected to the pushing translation track 335. The pushing translation track 335 extends along the first direction.

[0065] When the outer shell 910 has been placed at the loading station 3221, and the loading mechanism 310 has retracted to the output end of the outer shell feeding device 200, and the paper inserting mechanism 130 has inserted the separator paper 930 vertically into the paper inserting gap 3223, the pusher translation slider 334 moves along the pusher translation track 335 towards the direction close to the loading mechanism 310 until it reaches below the loading station 3221, the pressing station 3222 and the paper inserting gap 3223. It should be noted that at this time, in the first direction, the pusher plate 331 is on the side of the outer shell 910 located at the loading station 3221 away from the outer shell group 900 located at the pressing station 3222. Then, the pusher lifting driving member 333 drives the combination of the pusher plate 331 and the support plate 332 to rise until the support plate 332 lifts the outer shell 910 located at the loading station 3221, the separator paper 930 located in the paper inserting gap 3223 and the outer shell group 900 located at the pressing station 3222. The pusher translation slider 334 moves along the pusher translation track 335 towards the direction away from the loading mechanism 310 until the outer shell 910 located at the loading station 3221 and the separator paper 930 located in the paper inserting gap 3223 enter the pressing station 3222 and are jointly pressed with other outer shells 910 and separator papers 930 in the pressing station 3222 to form a new outer shell group 900. Then, the pusher lifting driving member 333 drives the combination of the pusher plate 331 and the support plate 332 to descend. During the descending process, the bottom of the outer shell group 900 first contacts the first support rod 321 and the second support rod 322 and stays at the pressing station 3222. The combination of the pusher plate 331 and the support plate 332 continues to descend until it will not interfere with the outer shell group 900 or other structures, and then the combination of the pusher plate 331 and the support plate 332 stops descending to prepare for the next pusher operation.

[0066] During the working process of the lithium battery outer shell packaging equipment, the above-mentioned loading action and pusher action are alternately performed to transport the outer shells 910 and the separator papers 930 one by one into the pressing station 3222 to form an outer shell group 900 with the outer shells 910 and the separator papers 930 alternately placed, realizing an automatic material sorting process.

[0067] Further, referring to Figure 3 and Figure 4, the sorting mechanism 320 further includes a first push plate 325 and a second push plate 326. Both the first push plate 325 and the second push plate 326 extend along the first direction and are spaced apart in the second direction. Part of the first push plate 325 and part of the second push plate 326 are located on both sides of the loading station 3221 in the second direction. The first push plate 325 and the second push plate 326 can move relatively closer to clamp both sides of the housing 910. After the loading mechanism 310 transports the housing 910 to the loading station 3221 and the paper inserting mechanism 130 inserts the separator paper 930 into the paper inserting gap 3223 in the vertical direction, the first push plate 325 and the second push plate 326 move closer to each other to clamp the housing 910 located at the loading station 3221, the separator paper 930 located in the paper inserting gap 3223, and at least part of the housing group 900 located at the pressing station 3222, so that the housing 910 located at the loading station 3221 and the separator paper 930 located in the paper inserting gap 3223 are initially aligned with the housing group 900 located at the pressing station 3222. Then, the pushing mechanism 330 pushes the housing 910 located at the loading station 3221 along the first direction, so that the housing 910 enters the pressing station 3222 from the loading station 3221, which is beneficial to improving the neatness of the housing group 900 and the consistency of the packaging of the housing 910.

[0068] Further, referring to Figure 3 and Figure 4 , the sorting mechanism 320 further includes a first brush 327. The first limiting member 323 and the second limiting member 324 are both connected with the first brush 327, and the first brush 327 faces the pressing station 3222. When the pushing mechanism 330 pushes the housing group 900 in the direction away from the loading mechanism 310, both sides of the housing group 900 come into contact with the first brush 327, and the first brush 327 will hinder the movement of the housing group 900 to prevent the housing 910 in the housing group 900 from tipping over under the action of inertia during the process of the pushing mechanism 330 pushing the housing group 900; in addition, before entering the packaging process, the housing 910 needs to go through an inspection process first. During the inspection process, the mouth part of the housing 910 may be deformed to a certain extent, making the part of the housing 910 near the mouth wider and the rest narrower, which may lead to insufficient close contact between adjacent housings 910. The pushing mechanism 330 pushes the housing group 900 to move, and the first brush 327 hinders the movement of the housing group 900, which can compact the housing group 900, so that the contact between adjacent housings 910 is closer, improving the reliability of the sorting process.

[0069] Further, referring to Figure 7, the first paper storage mechanism 110 further includes a blowing member 112. The air outlet of the blowing member 112 is located above the stack of separator papers. The blowing member 112 can blow a gas flow parallel to the separator paper 930 above the stack of separator papers to break the negative pressure between the topmost separator paper 930 and the adjacent separator papers 930, making the topmost separator paper 930 in a floating state, reducing the possibility that the first paper picking suction nozzle 120 picks up multiple separator papers 930 when picking up the separator paper 930, resulting in a messy stack of separator papers, and improving the reliability of paper picking.

[0070] Further, referring to Figure 7 , the first paper storage mechanism 110 further includes a paper separating member 113. The side wall of the first paper storage bin 111 has a notch for exposing the side of the stack of separator papers. The paper separating member 113 extends into the interior of the first paper storage bin 111 from the notch and is used to abut against the side of the stack of separator papers. The paper separating member 113 is a rack 1131 or a second brush 1132. More specifically, a plurality of paper separating members 113 can be provided, and some of the paper separating members 113 are racks 1131, and some of the paper separating members 113 are second brushes 1132. The paper separating member 113 can rub against the side of the stack of separator papers. When the first paper picking suction nozzle 120 picks up the topmost separator paper 930, causing the lower separator papers 930 to be lifted or stuck, the edges of the lower separator papers 930 are rubbed by the paper separating member 113, and can be more easily separated from the topmost separator paper 930, thereby further reducing the possibility that the first paper picking suction nozzle 120 picks up multiple separator papers 930 when picking up the separator paper 930, resulting in a messy stack of separator papers, and further improving the reliability of paper picking.

[0071] Further, referring to Figure 7 , the first paper storage mechanism 110 further includes a flapping member 114. The flapping member 114 is located on one side of the stack of separator papers. The flapping member 114 can move towards or away from the stack of separator papers to flap the side of the stack of separator papers. When the first paper picking suction nozzle 120 picks up the topmost separator paper 930, causing the lower separator papers 930 to be lifted or stuck, after the lower separator papers 930 fall back to the stack of separator papers under the action of factors such as their own gravity and the rubbing of the paper separating member 113, their positions may shift, resulting in a messy stack of separator papers and affecting the accuracy of paper picking. The flapping member 114 moves towards or away from the stack of separator papers to flap the side of the stack of separator papers, which can sort out the stack of separator papers and improve the neatness of the stack of separator papers, thereby improving the accuracy of paper picking.

[0072] Further, referring to Figure 7 , the first paper storage mechanism 110 further includes a flapping driving member 117. The output end of the flapping driving member 117 is connected to the flapping member 114 to drive the flapping member 114 to move towards or away from the stack of separator papers to flap the side of the stack of separator papers.

[0073] Further, referring to Figure 7, the first paper storage mechanism 110 further includes a limiting member 115. The limiting member 115 is connected to the inner wall of the first paper storage bin 111 and extends into the interior of the first paper storage bin 111. The limiting member 115 is located above the stack of separator papers. When the first paper pickup suction nozzle 120 picks up the topmost separator paper 930 and drives the topmost separator paper 930 to move upward, the limiting member 115 will block the picked separator paper 930, causing the picked separator paper 930 to deform, and further destroying the negative pressure between the picked separator paper 930 and the separator papers below, thereby further reducing the possibility that the first paper pickup suction nozzle 120 picks up multiple separator papers 930 when picking up the separator paper 930, and further improving the reliability of paper pickup.

[0074] Further, referring to Figure 6 and Figure 7 , there are two first paper storage mechanisms 110. The paper inserting device 100 further includes a switching track 140. Both of the two first paper storage mechanisms 110 are slidably connected to the switching track 140, and the two first paper storage mechanisms 110 can move along the switching track 140 to switch the first paper storage mechanism 110 corresponding to the first paper pickup suction nozzle 120. In actual use, stacks of separator papers are placed in the first paper storage bins 111 of both of the two first paper storage mechanisms 110. First, one of the first paper storage mechanisms 110 is made to correspond to the first paper pickup suction nozzle 120, and the first paper pickup suction nozzle 120 picks up the separator papers 930 in the corresponding first paper storage mechanism 110 one by one. When the separator papers 930 in this first paper storage mechanism 110 are completely consumed or nearly completely consumed, the two first paper storage mechanisms 110 can be moved along the switching track 140 so that the other first paper storage mechanism 110 corresponds to the first paper pickup suction nozzle 120. The above setting can increase the paper storage capacity in the paper inserting device 100. And when the separator papers 930 in one of the first paper storage mechanisms 110 are completely consumed or nearly completely consumed, switch the other first paper storage mechanism 110 to correspond to the first paper pickup suction nozzle 120, and then add separator papers 930 to the previous first paper storage mechanism 110. It is not necessary to stop the machine to replenish the separator papers 930, which is beneficial to improving production efficiency.

[0075] Further, referring to Figure 7, the first paper storage mechanism 110 further includes an adjustment track 116. The first paper storage bin 111 includes a first bin plate 1111, a second bin plate 1112, and a first bottom plate 1113. The first bottom plate 1113 is used to support the stack of separator papers, and the first bin plate 1111 and the second bin plate 1112 are used to jointly limit the stack of separator papers. At least one of the first bin plate 1111 and the second bin plate 1112 is slidably connected to the adjustment track 116, so that the first bin plate 1111 and the second bin plate 1112 can approach or move away from each other relatively. Different outer shells 910 require separator papers 930 of different sizes during packaging. By setting that the first bin plate 1111 and the second bin plate 1112 can approach or move away from each other relatively, the distance between the two can be adaptively adjusted to accommodate separator papers 930 of different sizes, improving the versatility of the paper inserting device 100.

[0076] Further, referring to Figure 6 , the paper inserting mechanism 130 includes a separator paper conveying mechanism 131 and a pressing wheel 132. The separator paper conveying mechanism 131 can adopt a conveyor belt. Specifically, two groups of conveyor belts can be adopted, and there is a gap for conveying the separator paper 930 between the two groups of conveyor belts; the pressing wheel 132 is located at the input end of the separator paper conveying mechanism 131 and can initially press the separator paper 930 sent by the first paper picking suction nozzle 120 to ensure that the separator paper 930 enters the separator paper conveying mechanism 131 in a flattened state.

[0077] Further, referring to Figure 3 and Figure 4 , the sorting mechanism 320 further includes a first adjustment bracket 328. At least one of the first limiting member 323 and the second limiting member 324 is movably connected to the first adjustment bracket 328, so that the first limiting member 323 and the second limiting member 324 can approach or move away from each other relatively. According to the size of the outer shell 910 to be packaged, the distance between the first limiting member 323 and the second limiting member 324 can be adaptively adjusted to limit outer shells 910 of different sizes, improving the versatility of the sorting device 300.

[0078] Further, referring to Figure 8 , the box feeding device 400 includes a box conveying mechanism 430, a third limiting member 440, a fourth limiting member 450, and a second adjustment bracket 460. The box conveying mechanism 430 is used to carry and convey the box 920. The third limiting member 440 and the fourth limiting member 450 are respectively arranged on both sides of the box conveying mechanism 430 and extend along the conveying direction of the box 920. At least one of the third limiting member 440 and the fourth limiting member 450 is movably connected to the second adjustment bracket 460, so that the third limiting member 440 and the fourth limiting member 450 can approach or move away from each other relatively. According to the size of the box 920 required for packaging, the distance between the third limiting member 440 and the fourth limiting member 450 can be adaptively adjusted to limit boxes 920 of different sizes, improving the versatility of the box feeding device 400.

[0079] Further, referring to Figure 9 , the moving mechanism 530 includes a flipping bracket 531, a lifting rod 532, a box-loading translation track 533 and a box-loading translation slider 534. The carrier plate 510 is rotatably connected to the flipping bracket 531. The flipping bracket 531 is connected to the lifting rod 532. The lifting rod 532 is movably connected to the box-loading translation slider 534 and can move relative to the box-loading translation slider 534 in the vertical direction. The box-loading translation slider 534 is slidably connected to the box-loading translation track 533. The box-loading translation slider 534 can move along the box-loading translation track 533 to move the housing group 900 from the output end of the sorting device 300 to the box-loading station 410.

[0080] In actual use, the lifting rod 532 drives the combination of the flipping bracket 531, the carrier plate 510 and the clamping mechanism 520 to descend until the surface of the carrier plate 510 for carrying the housing group 900 is flush or nearly flush with the upper surfaces of the first support rod 321 and the second support rod 322. The pushing mechanism 330 transports the housing group 900 that already has a predetermined number of housings 910 onto the carrier plate 510. The two clamping plates 521 of the clamping mechanism 520 clamp the housing group 900 on both sides of the housing group 900. Then the lifting rod 532 drives the combination of the flipping bracket 531, the carrier plate 510 and the clamping mechanism 520 to rise, and the carrier plate 510 rotates relative to the flipping bracket 531 so that the opening direction of the housing 910 in the housing group 900 changes from facing upward to facing downward. Then the box-loading translation slider 534 moves along the box-loading translation track 533 in the direction close to the box-loading station 410. Until after driving the housing group 900 to reach above the box-loading station 410, the lifting rod 532 drives the combination of the flipping bracket 531, the carrier plate 510 and the clamping mechanism 520 to descend so that the housing group 900 descends into the box 920 located at the box-loading station 410. Then the two clamping plates 521 of the clamping mechanism 520 release the housing group 900. The lifting rod 532 drives the combination of the flipping bracket 531, the carrier plate 510 and the clamping mechanism 520 to rise. The box-loading translation slider 534 moves along the box-loading translation track 533 in the direction away from the box-loading station 410. The carrier plate 510 rotates relative to the flipping bracket 531 so that the surface of the carrier plate 510 for carrying the housing group 900 returns to facing upward. The lifting rod 532 drives the combination of the flipping bracket 531, the carrier plate 510 and the clamping mechanism 520 to descend until the surface of the carrier plate 510 for carrying the housing group 900 is flush or nearly flush with the upper surfaces of the first support rod 321 and the second support rod 322 to prepare for the next box-loading operation.

[0081] Further, referring to Figure 1 and Figure 2 , the box feeding device 400 further has a paper-laying station 420. The lithium battery housing packaging device further includes a paper-laying device 600. Referring toFigure 10 The paper laying device 600 includes a second paper storage bin 610 and a second paper picking suction nozzle 620. The second paper storage bin 610 is used to place the stack of base papers. The second paper picking suction nozzle 620 can move above the stack of base papers to pick up a base paper, and can move to the paper laying station 420 to lay the base paper on the bottom of the box body 920. During the transportation of the box body 920 in the box body feeding device 400, it first reaches the paper laying station 420. The second paper picking suction nozzle 620 in the paper laying device 600 takes out the base paper from the second paper storage bin 610, then moves towards the paper laying station 420, and lays the base paper on the bottom of the box body 920, so as to reduce the collision between the outer shell 910 and the bottom of the box body 920, reduce the possibility of appearance defects caused by the collision between the outer shell 910 and the bottom of the box body 920, and further improve the reliability of the lithium battery outer shell packaging equipment.

[0082] Further, referring to Figure 10 The second paper storage bin 610 includes a second bottom plate 611, a first fixing plate 612, a second fixing plate 613, a first adjusting plate 614 and a second adjusting plate 615. The second bottom plate 611 is used to support the stack of base papers. The first fixing plate 612 and the second fixing plate 613 are both fixedly connected to the second bottom plate 611 and are perpendicular to each other. The first adjusting plate 614 is slidably connected to the second bottom plate 611 and is located on the opposite side of the first fixing plate 612. The first adjusting plate 614 can approach or move away from the first fixing plate 612. The second adjusting plate 615 is slidably connected to the second bottom plate 611 and is located on the opposite side of the second fixing plate 613. The second adjusting plate 615 can approach or move away from the second fixing plate 613. Different outer shells 910 require box bodies 920 of different sizes during packaging, and thus require base papers of different sizes. By setting that the first adjusting plate 614 can approach or move away from the first fixing plate 612 and the second adjusting plate 615 can approach or move away from the second fixing plate 613, the distance between the first adjusting plate 614 and the first fixing plate 612 and the distance between the second adjusting plate 615 and the second fixing plate 613 can be adaptively adjusted to adapt to base papers of different sizes, and the versatility of the paper laying device 600 is improved.

The opening member 730 has a connecting portion 731 and an abutting portion 732 that are connected to each other. The abutting portion 732 is bent downward relative to the connecting portion 731 to abut against the inner side wall of the box body 920. The connecting portion 731 is connected to the first moving plate 710 or the second moving plate 720. The first moving plate 710 and the second moving plate 720 can move away from each other to widen the opening of the box body 920, so as to reduce the possibility that the housing group 900 cannot be smoothly placed into the box body 920 due to the incomplete opening of the box body 920, thereby reducing the possibility of failure of the lithium battery housing packaging device and improving the packaging efficiency of the housing 910.

[0084] Further, referring to Figure 1 and Figure 2 , the lithium battery housing packaging device further includes a discharging device 800. The discharging device 800 is located at the output end of the box body feeding device 400.
