Description

Technical Field

[0001] The present invention belongs to the field of mechanical technology and relates to an automatic film tearing device, in particular to a battery disassembly device and a disassembly method. Background Art

[0002] When disassembling components such as batteries, it is necessary to remove the tabs and tear off the film. Existing automatic disassembly equipment often has problems such as incomplete functions and insufficient automation.

[0003] For example, Chinese patent literature has disclosed a film-tearing mechanism and a film-tearing device using the film-tearing mechanism [Chinese Patent No.: 202021681271.5]. The utility model discloses a film-tearing mechanism and a film-tearing device using the film-tearing mechanism. It adopts a different gluing method from the traditional one, sticking one end of the tape to one end of one pole ear of the battery, and sticking the other end of the tape to one end of the other pole ear of the battery, and both ends of the tape are exposed to the battery. The first film-tearing assembly and the second film-tearing assembly clamp the exposed parts of the two ends of the tape and flip the tape 180°, thereby peeling the upper film. Then the first film-tearing assembly and the second film-tearing assembly move at a uniform speed toward the tail end of the battery, tearing the upper film, and then tearing the lower film, and peeling the protective film from the battery. This film-tearing method can ensure that the force exerted on the surface of the battery is uniform when the film is torn, avoids the problem of liquid swelling, and reduces the defective rate of the battery when the film is torn. The film tearing mechanism of the utility model uses a motor to drive the tape to flip about 180 degrees. Flipping by the motor can more easily ensure the synchronization of the flipping actions at both ends, thereby ensuring that the force exerted on all parts of the battery during film removal is uniform.

[0004] The above technical solution lacks the structure and function of removing the tab, making it impossible to remove the upper tab of the battery. In addition, the above technical solution only provides one set of film tearing clamping structures, requiring the upper and lower films to be removed in steps, thereby reducing work efficiency and production capacity.

A number of rollers 10 are arranged and hinged on the two side walls of the fitting groove.

[0032] A suction material transfer mechanism is erected above the loading device / unloading device. The magazine box 3 with several products stacked inside is placed on the buffer platform 8 and supported on two rows of rollers 10 to form a rolling and sliding movement. The rotary motor drives the screw rod 9 to rotate forward / backward, driving the buffer platform 8 to correspond to the magazine positions 2 on the shifting plate 1 one by one, so that the magazine boxes 3 on the buffer platform 8 enter the magazine positions 2 on the shifting plate 1 one by one. The shifting electric cylinder horizontally moves the shifting plate 1 to alternately correspond the magazine boxes 3 to the loading / unloading positions. The shifting plate 1 is provided with openings corresponding to the magazine positions 2. The servo motor 4 drives the lead screw 5 to rotate.

[0033] As Figure 1 shown, the positioning device includes a positioning platform 11. A translation electric cylinder is arranged on the positioning platform 11. The translation electric cylinder reciprocally drives a positioning plate. At least one fixed position is arranged on the positioning plate. Limiters and buffers are arranged at both ends of the positioning plate on the positioning platform 11. A number of blocking blocks are arranged around the fixed position. The products are placed in the fixed position and the edges of the products are blocked by the surrounding blocking blocks to form circumferential fixation.

[0034] As Figures 4 to 6As shown in the figure, the pole ear extraction device includes a support, on which a first fixed material table 12 is set. A clamping cylinder is installed on one side of the first fixed material table 12. A clamping frame is fixedly connected to the telescopic rod of the clamping cylinder. The clamping frame is fixedly connected to a pushing block 13 through a connecting shaft. The clamping surface of the pushing block 13 faces the top surface of the first fixed material table 12.

The top of the upward rotating shaft of the rotary cylinder 15 is fixedly connected to a pressing block, and the pressing block is located above the top surface of the first fixed material table 12. Place the product on the top surface of the first fixed material table 12. Drive the pushing block 13 to translate and abut against one side edge of the product through the clamping cylinder, so that the product is clamped between the pushing block 13 and the baffle 14 to form planar positioning. Drive the pressing block to swing to the top surface of the product through the rotary cylinder 15 to form longitudinal pressing and fixation.

[0035] The pulling and extracting ear mechanism includes a pulling cylinder 16 fixedly installed on the support. The telescopic end of the pulling cylinder 16 is fixedly connected to a mounting seat. At least one pneumatic gripper 17 is installed on the mounting seat. The gripper head of the pneumatic gripper 17 faces the first fixed material table 12. A blanking box 18 is connected below the pneumatic gripper 17. The pneumatic grippers 17 are arranged corresponding to the pole ears of the battery one by one. The number of the pneumatic grippers 17 is two and they are arranged side by side. Drive the pneumatic gripper 17 to approach the product by translating the pulling cylinder 16. The pneumatic gripper 17 opens its gripper head to clamp the pole ear on the product. Finally, drive the pneumatic gripper 17 to move away from the product by translating the pulling cylinder 16, and at the same time pull out the clamped pole ear. The pneumatic gripper 17 opens its gripper head again, and the pole ear automatically falls into the blanking box 18.

[0036] As Figures 4 to 7 As shown in the figure, several suction cups are embedded on the top surface of the second fixed material table. The fixed material transfer mechanism includes a first slide table electric cylinder 19. The first slide table electric cylinder 19 drives a sliding frame 20 to translate. The top surface of the sliding frame 20 is a loading table. Pen-shaped cylinders 21 are symmetrically hinged on both sides of the sliding frame 20. The upward telescopic shaft of the pen-shaped cylinder 21 is hinged to one end of a bent pressing plate 22. The bent pressing plate 22 is hinged to the loading table in the middle. The other end of the bent pressing plate 22 swings and presses on the loading table. Retract the telescopic shafts of the pen-shaped cylinders 21 on both sides to drive the bent pressing plate 22 to swing outward, so that the inner end of the bent pressing plate 22 leaves the loading table to avoid the feeding space. Place the product on the loading table. Extend the telescopic shafts of the pen-shaped cylinders 21 on both sides to drive the bent pressing plate 22 to swing inward, so that the inner end of the bent pressing plate 22 presses the surface of the product to form fixation.

[0037] The upper film-tearing mechanism includes a top frame 23, on which an upper cylinder 24 is fixedly mounted. The lifting end of the upper cylinder 24 is fixedly connected to the upper frame, and the upper edge of the upper frame is vertically slidably connected to the upper stripping guide block 25. The upper frame is fixedly mounted with an upper pressing cylinder 27, and the lifting end of the upper pressing cylinder 27 is fixedly connected to an upper pressing plate 28, which presses the upper stripping guide block 25 downward. The lower film-tearing mechanism includes a bottom frame 29, on which a lower cylinder 30 is fixedly mounted. The lifting end of the lower cylinder 30 is fixedly connected to the lower frame, and the upper edge of the lower frame is vertically slidably connected to the lower stripping guide block 31. The lower frame is fixedly mounted with a lower pressing cylinder 33, and the lifting end of the lower pressing cylinder 33 is fixedly connected to a lower pressing plate 34, which presses the lower stripping guide block 31 upward. The upper cylinder 24 drives the entire upper frame to descend until the upper stripping guide block 25 contacts the top film of the product. The upper pressing cylinder 27 drives the upper pressing plate 28 to press the upper stripping guide block 25 downward to clamp the top film. The lower cylinder 30 drives the entire lower frame to rise until the lower peeling guide block 31 contacts the bottom film of the product, and the lower pressing cylinder 33 drives the lower pressing plate 34 to press the lower peeling guide block 31 upward to clamp the bottom film.

[0038] The upper frame is provided with a protruding upper mounting platform. The upper stripping guide block 25 is connected to the upper mounting platform via an upper guide post, forming a vertical sliding connection. The upper spring 26 is sleeved on the upper guide post. The upper frame is fixed with an upper vertical rail. The upper stripping guide block 25 is fixed to an upper slider, which is engaged with the upper vertical rail to form a sliding connection. The lower frame is provided with a protruding lower mounting platform. The lower stripping guide block 31 is connected to the lower mounting platform via a lower guide post, forming a vertical sliding connection. The lower spring 32 is sleeved on the lower guide post. The lower frame is fixed with a lower vertical rail. The lower stripping guide block 31 is fixed to a lower slider, which is engaged with the lower vertical rail to form a sliding connection. When the upper stripping guide block 25 presses the top surface of the product, the reaction force compresses the upper spring 26, and the upper stripping guide block 25 slides up along the upper vertical rail, thereby achieving elastic pressure on the top surface of the product. When the lower stripping guide block 31 presses the bottom surface of the product, the reaction force compresses the lower spring 32, and the lower stripping guide block 31 slides down along the lower vertical rail, thereby achieving elastic pressure on the bottom surface of the product. Use elastic pressure to prevent product surface from being crushed.

[0039] The upper stripping guide 25 has an inclined top surface with an upper flat groove recessed into it, into which the upper pressure plate 28 is pressed, creating a close contact. The lower stripping guide 31 has an inclined bottom surface with a lower flat groove recessed into it, into which the lower pressure plate 34 is pressed, creating a close contact. The flat groove provides a point of vertical pressure for the pressure plate, ensuring stability and enhancing the film's clamping force. The groove also cooperates with the edge of the pressure plate to position the film, preventing misalignment.

[0040] like Figures 4 to 6As shown in the figure, the waste collection mechanism includes a second slide electric cylinder 35. A first rotator 36 is translationally driven on the second slide electric cylinder 35. A clamping cylinder 37 is rotationally driven on the first rotator 36. A third slide electric cylinder 38 reciprocally drives a second rotator 39 beside the second slide electric cylinder 35. A waste manipulator 40 is rotationally driven on the second rotator 39. A waste collection box 41 is arranged beside the waste manipulator 40. The product after film tearing is clamped by the clamping cylinder 37. The product is reciprocally translated by the second slide electric cylinder 35, and the product is rotated by the first rotator 36. If waste products are generated, the first rotator 36 drives the clamping cylinder 37 to rotate towards the waste manipulator 40. The waste manipulator 40 clamps the waste products and rotates and translates them to be put into the waste collection box 41 above.

[0041] As Figure 4 shown in the figure, the material suction and transportation mechanism includes a transfer electric cylinder 42. The transfer electric cylinder 42 reciprocally drives a material transfer rack 43. A lifting cylinder 44 is installed on the material transfer rack 43. The lifting cylinder 44 drives at least one material suction disc 45 to lift and lower. A guide column 46 is fixedly arranged on the material suction disc 45. The guide column 46 passes through the material transfer rack 43 to form a vertical sliding connection. A limit buffer 47 is fixedly connected to the top of the guide column 46. A limit column protrudes from the material transfer rack 43. The limit buffer 47 confronts the limit column to form a limit abutment. The material suction disc 45 is reciprocally translated by the transfer electric cylinder 42, the material suction disc 45 is lifted and lowered by the lifting cylinder 44, and the product is sucked by the material suction disc 45. During the lifting and lowering process of the material suction disc 45, the guide column 46 synchronously lifts and slides. When the limit buffer 47 abuts against the limit column, the material suction disc 45 stops descending to reach the limit position.

[0042] As Figure 1 shown in the figure, the inspection device includes an inspection platform 48. A transverse movement electric cylinder is arranged on the inspection platform 48. The transverse movement electric cylinder reciprocally drives an inspection plate 49. At least one fixed station is arranged on the inspection plate 49. Limiters and buffers are arranged at both ends of the inspection platform 48 with respect to the inspection plate 49. An inspection scanner 50 is erected beside the inspection platform 48. The inspection plate 49 is reciprocally moved by the transverse movement electric cylinder to align the product in the fixed station on the inspection plate 49 with the inspection scanner 50. The product is scanned by the inspection scanner 50 to judge whether the product is qualified. The transverse movement range of the inspection plate 49 is restricted by the limiters and buffers at both ends. Embodiment 2

[0043] Based on Embodiment 1, the difference in this embodiment is:

[0044] A disassembly method of a battery disassembly device includes the following steps:

[0045] S1. Place a magazine 3 with several products stacked inside it onto the buffer table 8 of the loading device and place it on two rows of rollers 10. Start the rotary motor to translate the buffer table 8 to correspond one-to-one with the magazine positions 2 on the transposition plate 1, pushing the magazines 3 on the buffer table 8 into the magazine positions 2 on the transposition plate 1 one by one. Start the shifting electric cylinder to translate the transposition plate 1 so that the magazines 3 alternately correspond to the loading positions.

[0046] S2. The first material suction and transfer mechanism drives the material suction plate 45 to move horizontally, and the lifting cylinder 44 drives the material suction plate 45 to descend. The material suction plate 45 sucks the product in the magazine box 3 on the transposition plate 1 and transfers it to the positioning device for secondary positioning of the product;

[0047] S3, then the second material suction and transfer mechanism grabs the product from the positioning device and transfers it to the fixed material table 12 of the tab extraction device for fixing, starts the pulling cylinder 16 to extend the pneumatic clamp 17 close to the product, the pneumatic clamp 17 opens its claws to clamp the tab on the product, and then the pulling cylinder 16 pulls the pneumatic clamp 17 back away from the product, and at the same time pulls off the clamped tab, the pneumatic clamp 17 opens its claws again, and the tab automatically falls into the blanking box 18;

[0048] S4, then use the second material suction and transfer mechanism to grab the product from the fixed material table 12 and transfer it to the fixed material table 2 of the film tearing device for fixation, start the slide table electric cylinder 19 to move the sliding frame 20 to the fixed material table 2 to support the product, and the pen-shaped cylinders 21 on both sides extend the telescopic shaft to drive the bending pressure plate 22 to swing inward, so that the inner end of the bending pressure plate 22 presses the surface of the product to form a fixed surface; the slide table electric cylinder 19 moves the sliding frame 20 to the upper film tearing mechanism and the lower film tearing mechanism, and the upper cylinder 2 4 drives the entire upper frame to descend until the upper peeling guide block 25 contacts the top film of the product. The upper pressure cylinder 27 drives the upper pressure plate 28 to press the upper peeling guide block 25 downward to clamp the top film. The lower cylinder 30 drives the entire lower frame to ascend until the lower peeling guide block 31 contacts the bottom film of the product. The lower pressure cylinder 33 drives the lower pressure plate 34 to press the lower peeling guide block 31 upward to clamp the bottom film. The upper cylinder 24 moves upward and the lower cylinder 30 moves downward to simultaneously tear off the top and bottom films.

[0049] S5. Start the clamping cylinder 37 to clamp the product after film tearing. The slide cylinder 2 35 drives the product to move back and forth. If waste is generated, the rotator 1 36 drives the clamping cylinder 37 to turn to the waste manipulator 40. The waste manipulator 40 clamps the waste and moves it to the top of the waste collection box 41 to put the waste into the waste collection box;

[0050] S6. The qualified product is moved to the fixed position of the inspection device by the second slide cylinder 35 and the clamping cylinder 37. The transverse cylinder is activated to drive the inspection plate 49 to move back and forth so that the product in the fixed position on the inspection plate 49 is aligned with the inspection scanner 50. The inspection scanner 50 scans the product to determine whether the product is qualified.

[0051] S7. Then, use the third material suction and transfer mechanism to grab the product from the inspection board 49 and transfer it to the magazine 3 of the blanking device. Start the displacement electric cylinder to translate the displacement plate 1 to make the magazine 3 alternately correspond to the blanking position. Start the rotation motor to translate the buffer table 8 to correspond to the magazine positions 2 on the displacement plate 1 one by one. Push the full magazine 3 to the buffer table 8 and place it on two rows of rollers 10, and finally collect the products.

[0052] Compared with the prior art, the present battery disassembly device and disassembly method have the following beneficial effects:

[0053] 1. The present invention arranges the feeding, positioning, pole ear pulling, film tearing, inspection and blanking in sequence in a reasonable way, adds processes such as pole ear pulling, inspection and waste product exclusion.
