Detailed implementation manners

[0045] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0046] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0047] Please refer to Figure 1-14, the present invention provides a technical solution: a fully automatic anti-magnetic packaging line for lithium battery diaphragms, including: a coil loading mechanism 1, a coil wrapping mechanism 2, a casing mechanism 3, a coil unloading mechanism 4, and a packaging material feeding mechanism 5.

[0048] Please refer to Figure 1-3 , the coil loading mechanism 1 includes a material rack 11, a coil loading manipulator 12, and an NG flow line 13. The diaphragm coil 9 is placed on the material rack 11. A core 91 for winding the diaphragm is provided inside the diaphragm coil 9. The core 91 includes an inner tube body 911, an outer tube body 912, and reinforcing rib plates 913. A plurality of reinforcing rib plates 913 are provided between the inner tube body 911 and the outer tube body 912. At least one first pneumatic gripper 121 is provided on the coil loading manipulator 12. A first barcode scanning device 122 is provided on one side of the first pneumatic gripper 121. The NG flow line 13 is provided on one side of the coil loading manipulator 12. The coil loading mechanism 1 includes three material racks 11, and the three material racks 11 are arranged in a "pin" shape. The three material racks 11 surround the coil loading manipulator 12 to achieve multi-station loading and ensure the loading efficiency of the diaphragm coil 9.

[0049] When the coil loading mechanism 1 works, the coil loading manipulator 12 grabs the diaphragm coil 9 from the material rack 11 through the first pneumatic gripper 121 and places it on the coil loading jig 22 for stacking. Before grabbing, the barcode on the diaphragm coil 9 is identified by the first barcode scanning device 122. If the diaphragm coil 9 fails to be correctly identified, the coil loading manipulator 12 places it on the NG flow line 13 after grabbing, so that the problematic diaphragm coil 9 flows out of the packaging line. Subsequently, it can be scanned by the staff outside the packaging line and then reloaded into the material rack 11. A plurality of first pneumatic grippers 121 are provided on the coil loading manipulator 12. Specifically, there are 3 in the attached drawings, so that the coil loading manipulator 12 can grab multiple diaphragm coils 9 at one time, which is convenient for stacking.

[0050] Please refer to Figure 1 , 4-6, the coil wrapping mechanism 2 includes a double-speed chain conveyor line 21, a coil loading jig 22, a central paper tube bagging machine 23, and a coil bagging machine 24. At one end of the double-speed chain conveyor line 21, there is a front lifting mechanism 211, and at the opposite end, there is a rear lifting mechanism 212. The coil loading manipulator 12 is arranged on one side of the front lifting mechanism 211. On the double-speed chain conveyor line 21, there is a transplanting tray 213. The coil loading jig 22 is fixedly installed on the transplanting tray 213. The coil loading jig 22 includes a bottom plate 221, a support block 222, and positioning rods 223. The bottom plate 221 is fixedly installed on the transplanting tray 213. On one side of the bottom plate 221, there is a first notch 2211. On the support block 222, there is a second notch corresponding to the first notch 2211 in position. A number of positioning rods 223 are arranged circumferentially along the support block 222. The positioning rods 223 are perpendicular to the bottom plate 221. The positioning rods 223 extend into the inner part of the core 91 and contact the inner wall of the outer tube 912. The central paper tube bagging machine 23 is arranged on one side of the double-speed chain conveyor line 21. Between the central paper tube bagging machine 23 and the double-speed chain conveyor line 21, there is a central paper tube loading manipulator 231. On one side of the central paper tube bagging machine 23, there is a central paper tube lifting machine 232. The central paper tube lifting machine 232 is used to send the paper tube into the central paper tube bagging machine 23. The central paper tube bagging machine 23 is used to bag the paper tube and heat-shrink seal it. The central paper tube loading manipulator 231 is used to insert the bagged paper tube into the inner tube 911 of the core 91 in the diaphragm coil 9. The coil bagging machine 24 is arranged on one side of the double-speed chain conveyor line 21. The coil bagging machine 24 is used to bag the diaphragm coil 9 on the coil loading jig 22;

[0051] When the coil wrapping mechanism 2 works, the coil loading manipulator 12 places the diaphragm coil 9 on the coil loading jig 22 in the front lifting mechanism 211. After 2 - 3 rolls of diaphragm coils 9 are stacked on the coil loading jig 22 according to the packaging requirements, it is moved out of the front lifting mechanism 211 through the transplanting tray 213 and moved to one side of the central paper tube loading manipulator 231. After the central paper tube lifting machine 232 sends the paper tube into the central paper tube bagging machine 23, the central paper tube bagging machine 23 bags the paper tube and heat-shrink seals it. The paper tube bagging machine is a prior art, and its specific working principle will not be elaborated here. Then the central paper tube loading manipulator 231 clamps the bagged paper tube and inserts it into the inner tube 911 of the core 91 in the diaphragm coil 9. Then the transplanting tray 213 drives the coil loading jig 22 to move to the coil bagging machine 24. The coil bagging machine 24 bags the diaphragm coil 9 on the coil loading jig 22, and a heating device (not shown in the figure) is arranged on the double-speed chain conveyor line 21 at the coil bagging machine 24. Through the first notch 2211 on the bottom plate 221 in the coil loading jig 22, the bottom of the plastic bag sleeved on the diaphragm coil 9 is sealed. The bagged diaphragm coil 9 continues to be conveyed on the double-speed chain conveyor line 21 with the coil loading jig 22. When bagging the central paper tube and the coil, the "bags" sleeved are all transparent plastic bags.

[0052] Please refer to Figure 1 and 7 -8. The casing mechanism 3 includes a support frame 31, an X-direction movement module 32, a Z-direction movement module 33, an intubation component 34, and a casing elevator 35. The double-speed chain conveyor line 21 passes through the support frame 31. The X-direction movement module 32 is fixedly installed on the support frame 31. The Z-direction movement module 33 is slidably connected to the X-direction movement module 32. The intubation component 34 is slidably connected to the Z-direction movement module 33. The position of the intubation component 34 is correspondingly arranged above the double-speed chain conveyor line 21. A casing elevator 35 is arranged on one side of the support frame 31;

[0053] When the casing mechanism 3 works, the coiled material loading fixture 22 drives the diaphragm coiled material 9 with the center paper tube already inserted thereon to move below the intubation component 34. The intubation component 34 moves to the discharge port of the casing elevator 35 through the X-direction movement module 32, clamps the casing through a pneumatic gripper, and after clamping, the casing rises and moves along the X direction to above the double-speed chain conveyor line 21, and then descends through the Z-direction movement module 33 to sleeve the casing on the top of the center paper tube protruding from the diaphragm coiled material 9. The casing can position the diaphragm coiled material 9 on the center paper tube, prevent the diaphragm coiled material 9 from shifting on the center paper tube, ensure the stability of the diaphragm coiled material 9 after being placed in the packaging material, prevent damage to the lithium battery diaphragm, and improve the yield rate of the diaphragm.

[0054] Please refer to Figure 1 and 9 -10. The coiled material unloading mechanism 4 includes an unloading manipulator 41 and an unloading roller conveyor line 42. The unloading manipulator 41 is arranged on one side of the rear lifting mechanism 212. The unloading manipulator 41 is used to clamp the diaphragm coiled material 9 on the coiled material loading fixture 22; A clamping member 43 is arranged on the unloading manipulator 41. The clamping member 43 includes a mounting plate 431, a first end plate 432, a second end plate 433, a clamping plate 434, a first driving cylinder 435, and an air nozzle 436. The first end plate 432 and the second end plate 433 are symmetrically arranged on both sides of the mounting plate 431. The first driving cylinder 345 is fixedly installed on the first end plate 432. The cylinder rod of the first driving cylinder 345 passes through the first end plate 432 and then connects to the clamping plate 434. An air nozzle 346 is arranged on the second end plate 433.

[0055] When the coiled material unloading mechanism 4 works, the coiled material loading fixture 22 drives the diaphragm coiled material 9 with the casing already inserted thereon to move to the rear lifting mechanism 212. The unloading manipulator 41 clamps the diaphragm coiled material 9 through the clamping member 43 and places the diaphragm coiled material 9 into the plastic packaging box 6 on the unloading roller conveyor line 42. After the diaphragm coiled material 9 on the coiled material loading fixture 22 is taken away, it descends at the rear lifting mechanism 212 and moves along the double-speed chain conveyor line 21 to the front lifting mechanism 211 for circulation.

[0056] When the clamping member 43 specifically clamps the diaphragm coil 9, the diaphragm coil 9 is located between the first end plate 432 and the second end plate 433. During specific clamping, the second end plate 433 at the bottom of the diaphragm coil 9 is inserted into the second notch on the coil loading fixture 22; the first driving cylinder 435 at the top of the diaphragm coil 9 drives the clamping plate 434 to cooperate with the second end plate 433 to clamp the diaphragm coil 9. The air nozzle 346 is used to blow the transparent plastic bag sleeved on the diaphragm coil 9 to prevent the transparent plastic bag from affecting the insertion and clamping of the second end plate 433.

[0057] Please refer to Figure 1 、 9 -10. There is also a vibrating bowl 44 provided on one side of the rear lifting mechanism 212. A desiccant packet is provided inside the vibrating bowl 44. A second pneumatic gripper 437 is provided on the back of the mounting plate 431. When the clamping member 43 clamps the diaphragm coil 9, the second pneumatic gripper 437 is correspondingly arranged at the discharge port of the vibrating bowl 44.

[0058] When the clamping member 43 clamps the diaphragm coil 9, the second pneumatic gripper 437 simultaneously grabs the desiccant packet sent out by the vibrating bowl 44, so that the desiccant packet is put in at the same time when the diaphragm coil 9 is put into the plastic packaging box 6 by the blanking manipulator 41, eliminating the need for an additional process for putting in the desiccant packet and improving the packaging efficiency.

[0059] Please refer to Figure 1 , the coil blanking mechanism 4 further includes a pallet feeder 45, a labeling machine 46, a film wrapping machine 47 and an arrow threading and packing machine 48. The pallet feeder 45, the labeling machine 46, the film wrapping machine 47 and the arrow threading and packing machine 48 are arranged in sequence along the conveying direction of the blanking roller conveyor line 42. The pallet feeder 45 is used to feed the pallet 451 into the blanking roller conveyor line 42.

[0060] After the pallet feeder 45 feeds the pallet 451 into the blanking roller conveyor line 42, the plastic packaging box 6 is directly placed on the pallet 451 for subsequent transportation. The labeling machine 46 labels the packaging box formed by combining the upper and lower plastic packaging boxes 6. The film wrapping machine 47 winds a film on the surface of the packaging box, and finally, it is packed by the arrow threading and packing machine to achieve further packaging of the lithium battery diaphragm. After the arrow threading and packing machine finishes packing, the lithium battery diaphragm completes the packaging and blanking.

[0061] Please refer to Figure 1 、 11-13, The packaging material feeding mechanism 5 includes a packaging material drum feeding line 51, a tray feeding assembly 52, and a packaging material loading and unloading manipulator 53. The plastic packaging boxes 6 are stacked on the packaging material drum feeding line 51. One end of the packaging material drum feeding line 51 extends into the tray feeding assembly 52. The tray feeding assembly 52 is used to separate two vertically stacked plastic packaging boxes 6. The packaging material loading and unloading manipulator 53 is arranged on one side of the tray feeding assembly 52. A material taking frame 531 is arranged on the packaging material loading and unloading manipulator 53. The material taking frame 531 is rotatably installed on the packaging material loading and unloading manipulator 53. Symmetrically arranged suction cups 532 are arranged on the upper and lower sides of the material taking frame 531. The suction cups 532 are used to suck the plastic packaging boxes 6.

[0062] When the packaging material feeding mechanism 5 works, the plastic packaging boxes 6 are stacked on the packaging material drum feeding line 51. After the plastic packaging boxes 6 are sent into the frame 521 of the tray feeding assembly 52 by the packaging material drum feeding line 51, the tray feeding assembly 52 separates two vertically stacked plastic packaging boxes 6 and lifts them, facilitating the packaging material loading and unloading manipulator 53 to pick up the plastic packaging boxes 6 through the material taking frame 531. The material taking frame 531 can suck two plastic packaging boxes 6 on one side through the suction cups 532 on the upper and lower sides. After the packaging material loading and unloading manipulator 53 picks up the plastic packaging boxes 6, it places them on the blanking drum conveying line 42, facilitating the blanking manipulator 41 to put the diaphragm coil 9 into the plastic packaging boxes 6. After the accommodation cavity of the plastic packaging box 6 is filled with the diaphragm coil 9, the packaging material loading and unloading manipulator 53 rotates the material taking frame 531 so that the plastic packaging boxes 6 on the material taking frame 531 have their openings facing downwards and are buckled with the plastic packaging boxes 6 on the blanking drum conveying line 42 to form a whole packaging box, realizing the packaging of the diaphragm coil 9.

[0063] The tray feeding assembly 52 includes a frame 521, a lifting power element 522, and a tray separating element 523. Symmetrically arranged lifting power elements 522 are arranged on a pair of opposite inner side walls of the frame 521. The tray separating element 523 is fixedly installed on the lifting power element 522. The lifting power element 522 is used to drive the tray separating element 523 to move up and down. The tray separating element 523 includes separating sheets 5231 symmetrically arranged on both sides of the lifting power element 522.

[0064] When the tray feeding assembly 52 works, for the stacked plastic packaging boxes 6 sent into the frame 521, the lifting power element 522 drives the tray separating element 523 to descend to an appropriate height. The separating sheets 5231 extend forward through the driving elements (such as cylinder driving elements) arranged on the back and are inserted between the flanges of two vertically stacked plastic packaging boxes 6. Then the lifting power element 522 drives the tray separating element 523 to rise, realizing the separation of two vertically stacked plastic packaging boxes 6.

[0065] Please refer to Figure 14, the packaging material feeding mechanism 5 further includes a packaging material positioning component 54. The packaging material positioning component 54 includes a table 541, a fixed baffle 542, a movable baffle 543, and a driving cylinder 544. A fixed baffle 542 is provided on one side of the table 541, and a movable baffle 543 is provided on the opposite side. The cross-section of the fixed baffle 542 is in an "L" shape. The driving cylinder 544 is fixedly installed on the table 541, and the movable baffle 543 is fixedly installed at the output end of the driving cylinder 544.

[0066] To ensure that the diaphragm coil 9 is accurately placed into the receiving groove of the plastic packaging box 6 by the blanking manipulator 41, before the packaging material loading and unloading manipulator 53 places the plastic packaging box 6 on the blanking roller conveyor line 42, it is first placed on the packaging material positioning component 54 for positioning, ensuring that each time the blanking manipulator 41 places the plastic packaging box 6 on the blanking roller conveyor line 42, the position where the suction cup 532 sucks the plastic packaging box 6 is fixed, so that the placement position of the plastic packaging box 6 remains unchanged each time.

[0067] When the packaging material positioning component 54 works, an adjacent side wall of the plastic packaging box 6 is fixed by the fixed baffle 542, and the other adjacent side wall is positioned by the driving cylinder 544 pushing the movable baffle 543. The cross-section of the fixed baffle 542 is in an "L" shape, precisely an inverted "L" shape. The horizontally arranged plate on the upper side of the fixed baffle 542 presses the plastic packaging box 6, positioning the plastic packaging box 6 fully from both the horizontal and vertical directions.

[0068] Working principle: The coil loading manipulator 12 grabs the diaphragm coil 9 from the material rack 11 through the first pneumatic gripper 121 and places it on the coil loading jig 22 for stacking. Then, the central paper tube loading manipulator 231 grabs the paper tube after sleeving and inserts it into the diaphragm coil 9 stacked on the coil loading jig 22. After that, the transfer tray 213 drives the coil loading jig 22 to move to the coil bagging machine 24. The coil bagging machine 24 bags and heat-shrink seals the diaphragm coil 9 on the coil loading jig 22. The coil loading jig 22 drives the diaphragm coil 9 with the central paper tube already inserted thereon to move under the tube inserting component 34 for tube insertion. Then, the coil loading jig 22 drives the diaphragm coil 9 with the tube already inserted thereon to move to the rear lifting mechanism 212. The blanking manipulator 41 grabs the diaphragm coil 9 through the clamping member 43 and places the diaphragm coil 9 into the plastic packaging box 6 on the blanking roller conveyor line 42. After a plastic packaging box 6 is filled, the packaging material loading and unloading manipulator 53 rotates the material taking frame 531 so that the plastic packaging box 6 on the material taking frame 531 has its opening facing downward and is buckled with the plastic packaging box 6 on the blanking roller conveyor line 42 to form a whole to form a packing box, realizing the packaging of the diaphragm coil 9.
