Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] Please see Figure 1As shown, the present invention is a battery packing device, including a conventional workbench 1; a pair of support shafts 2 are vertically and rotatably connected side by side on the upper surface of the workbench 1; conventional film rolls 3 are fixedly sleeved on both support shafts 2; a plastic shell conveying mechanism 4 is horizontally installed between the two film rolls 3; a film guiding mechanism 5 and a plastic shell positioning mechanism 6 are installed side by side on the plastic shell conveying mechanism 4; a film cutting mechanism 7 and a film flipping mechanism 8 are installed between the film guiding mechanism 5 and the plastic shell positioning mechanism 6. In use, multiple battery casings are placed side-by-side on the casing conveying mechanism 4, with the distance between two adjacent casings matching the width of the casing. The film guiding mechanism 5 synchronously conveys the film on two film rolls 3. When a battery casing moves to the position corresponding to the film guiding mechanism 5, the two sections of film are attached to the side walls of the casing. Then, after one casing is conveyed to the position corresponding to the casing positioning mechanism 6 and the other casing is conveyed to the position corresponding to the film guiding mechanism 5, the film cutting mechanism 7 cuts the film between the two adjacent casings in the middle. At the same time, the film flipping mechanism 8 flips the cut film and attaches it to the opposite inner surfaces of the two adjacent casings. This process is repeated to achieve continuous coating of multiple battery casings, which not only effectively improves the coating efficiency and effect of the battery casings but also reduces the labor intensity of workers and ensures the coating quality of the battery casings.

[0033] Example 2:

[0034] Based on Example 1, as follows Figure 2 As shown, the plastic shell conveying mechanism 4 includes a pair of side support beams 401 horizontally bolted to the upper surface of the workbench 1; a pair of rollers 402 are rotatably connected side by side between the two side support beams 401; one end of one roller 402 is coaxially fixed to the output shaft of a servo motor 403 by a conventional coupling in the art; the two rollers 402 are connected by a conveyor belt 404; a plurality of rubber-made protrusions 405 are riveted side by side along the axial direction of the rollers 402 on the outer surface of the conveyor belt 404; the horizontal position of the upper outer surface of the protrusions 405 is higher than the horizontal position of the upper surface of the side support beams 401. In use, multiple battery shells are placed sequentially on the protrusion 405, and the distance between two adjacent battery shells is controlled to be consistent with the width of the battery shell. Since the horizontal position of the upper outer surface of the protrusion 405 is higher than the horizontal position of the upper surface of the side support beam 401, the coating effect of the battery shell can be guaranteed, and interference between the film and the side support beam 401 or the conveyor belt 404 can be avoided. The servo motor 403 drives the roller 402 to rotate intermittently, so that the conveyor belt 404 intermittently transports the battery shell, effectively ensuring the conveying effect of the battery shell.

[0035] Among them, such as Figure 2As shown, a plastic shell alignment mechanism 9 is installed at the input end of the plastic shell conveying mechanism 4. The plastic shell alignment mechanism 9 includes a pair of first mounting plates 901 that are vertically bolted to the two side support beams 401. The opposite outer surfaces of the two first mounting plates 901 are horizontally bolted to conventional first cylinders 902. The output ends of the two first cylinders 902 slide through the two first mounting plates 901 and are vertically bolted to alignment plates 903. The extension and retraction direction of the output end of each first cylinder 902 is parallel to the length direction of the roller 402. In use, when the battery plastic shell is conveyed between the two alignment plates 903, the two first cylinders 902 drive the two alignment plates 903 to move in close proximity, causing the two alignment plates 903 to push the battery plastic shell to the middle of the conveyor belt 404. This not only avoids collisions between the battery plastic shell and the film guiding mechanism 5, but also ensures that the two film segments are simultaneously attached to the opposite sidewalls of the battery plastic shell, effectively guaranteeing the film effect of the battery plastic shell.

[0036] Example 3:

[0037] Based on Example 2, as follows Figure 3-5As shown, the film guiding mechanism 5 includes two pairs of second mounting plates 501 vertically bolted to the side support beams 401; the upper parts of the two pairs of second mounting plates 501 are horizontally bolted to conventional second cylinders 502, and the extension and retraction direction of the output end of each second cylinder 502 is parallel to the length direction of the roller 402; the output ends of the two pairs of second cylinders 502 slide through the two pairs of second mounting plates 501 and are vertically bolted to first transmission columns 503; between the two pairs of first transmission columns 503, there are horizontally arranged bearing strips 504 corresponding to the side support beams 401, and each bearing strip 504... The edges of each of the two bearing strips 504 are connected to the upper ends of the adjacent pair of first drive columns 503; the first drive columns 503 are connected to the bearing strips 504 by welding; the lower surfaces of the two bearing strips 504 are vertically rotatably connected to multiple first guide rollers 505 along the length direction; the ends of the two bearing strips 504 near the input end of the conveyor belt 404 each have an outward fold 506, that is, the outward fold 506 bends towards the side of the bearing strip 504 away from the conveyor belt 404, and the angle between the outward fold 506 and the bearing strip 504 is 135 degrees; the lower surfaces of the two outward folds 506 are vertically rotatably connected to a pair of second guide rollers 507. In use, the free end of the film on the film roll 3 is first passed around a second guide roller 507 and then another second guide roller 507. The film is then unfolded along the conveying direction of the conveyor belt 404 on the side of the first guide roller 505 close to the conveyor belt 404. When the battery shell is conveyed between the two support plates 504, the second cylinder 502 drives the two support plates 504 to move in close proximity through the first transmission column 503, causing the film to adhere to the side wall of the battery shell. At the same time, the first guide roller 505 rolls the side wall of the battery shell, which can effectively improve the adhesion effect of the film on the battery shell. Then, as the battery continues to be conveyed, the film on the film roll 3 continues to be passively released, which can ensure that the opposite side walls of multiple battery shells are covered with film, effectively ensuring the coating effect of the battery shell.

[0038] Among them, such as Figure 3-4 and Figure 6As shown, the plastic shell positioning mechanism 6 includes a pair of third mounting plates 601 that are vertically bolted to the two side support beams 401; the upper part of each of the two third mounting plates 601 is horizontally bolted to a conventional third cylinder 602 in the art, and the extension and retraction direction of the output end of each third cylinder 602 is parallel to the length direction of the roller 402; the output ends of the two third cylinders 602 slide through the two third mounting plates 601 and are vertically bolted to a second transmission column 603; the upper ends of the two second transmission columns 603 are horizontally welded to positioning strips 604 that are parallel to the side support beams 401; the lower surfaces of the two positioning strips 604 are vertically rotatably connected to multiple third guide rollers 605 along the length direction. In use, when a battery casing moves between two positioning plates 604, the third cylinder 602 drives the two positioning plates 604 to move in close proximity via the second transmission column 603, causing the third guide roller 605 to come into contact with the side wall of the battery casing, which can effectively position the battery casing and ensure the coating effect of the battery casing.

[0039] Example 4:

[0040] Based on Example 3, as follows Figure 7-11As shown, the film cutting mechanism 7 includes a pair of fourth support plates 701 vertically bolted to the two side support beams 401; the upper parts of both fourth support plates 701 are horizontally bolted to conventional fourth cylinders 702, and the extension and retraction direction of the output end of each fourth cylinder 702 is parallel to the length direction of the roller 402; the output ends of the two fourth cylinders 702 slide through the two fourth support plates 701 and are vertically bolted to conventional blade holders 703; conventional cutters 704 are vertically bolted to both blade holders 703; film turning machine The structure 8 includes a pair of mounting brackets 801 vertically bolted to the two side support beams 401; the mounting brackets 801 have a "Π" shaped structure; a pair of protrusions 802 are welded side by side to the upper part of each mounting bracket 801, and the two protrusions 802 on each mounting bracket 801 are symmetrically arranged with respect to the adjacent cutter 704; the protrusions 802 are located on the side of the mounting bracket 801 near the conveyor belt 404; a rotating shaft 803 is vertically rotatably connected to each pair of protrusions 802; a rotating bar 804 with a "「" shaped structure is vertically bolted to the lower end of each pair of rotating shafts 803; the two pairs of rotating bars 804... Each pair of flip plates 805 is vertically welded to its lower end; each pair of flip plates 805 has a negative pressure chamber inside, and each flip plate 805 is connected to an air suction nozzle 806 that communicates with the negative pressure chamber; the air suction nozzle 806 is a conventional component in this field; each pair of flip plates 805 has multiple negative pressure suction holes 807 arranged side by side on one side, which communicate with the negative pressure chamber; when the two flip plates 805 mounted on the same mounting bracket 801 are on the same plane, the air suction nozzle 806 is located on the side of the flip plate 805 away from the protrusion 405, and the negative pressure suction hole 807 is located on the side of the flip plate 805 closer to the protrusion 405. On one side of the protruding strip 405; the upper part of each of the two mounting brackets 801 is horizontally bolted with a conventional fifth cylinder 808 in the art, and the extension and retraction direction of the output end of each fifth cylinder 808 is parallel to the length direction of the roller 402; the output end of each of the two fifth cylinders 808 is horizontally bolted with a double-sided rack 809; a pair of gears 810 are meshed on each of the two double-sided racks 809; the two pairs of gears 810 are respectively keyed to the upper ends of the two pairs of rotating shafts 803, and the two gears 801 on each mounting bracket 801 are respectively arranged on the opposite sides of the adjacent double-sided racks 809.In use, first, place the two flip plates 805, which are mounted on the same mounting bracket 801, on the same plane. Then, attach the free end of the film to one of the flip plates 805 near the input end of the conveyor belt 404. Next, transport the first battery casing between the two support plates 504, ensuring that the distance between the free end of the film and the first battery casing is half the width of the battery casing. The fifth cylinder 808 drives the flip plate 805 to rotate via the double-sided rack 809, gear 810, rotating shaft 803, and rotating bar 804, causing the free end of the film to be flipped and attached to one side wall of the first battery casing. Then, the negative pressure suction hole 807 loses its negative pressure state and the flip plate 805 resets, continuing to transport the battery casing. The film on the film roll 3 is also released simultaneously, and the released film is attached to the side walls of multiple battery casings on the conveyor belt 404 in sequence. When a battery casing is transported between the two positioning plates 604... Furthermore, after another battery casing is conveyed to the distance between the two supporting plates 504 and between the two adjacent battery casings and the cutter 704, the negative pressure suction hole 807 sucks up the film. The fourth cylinder 702 drives the cutter 704 to cut the film through the cutter holder 703. Then, the fifth cylinder 808 drives the flipping plate 805 to rotate through the double-sided rack 809, gear 810, rotating shaft 803 and rotating bar 804, causing the cut film to be flipped and attached to the opposite inner surfaces of the two adjacent battery casings. The two fifth cylinders 808 perform their actions in sequence, thereby realizing the film coating process of the battery casings. Then the flipping plate 805 is reset, the battery casings continue to be conveyed, and the above actions are repeated, thereby realizing the film coating process of multiple battery casings. Moreover, since the segmented film coating method is adopted, it is also convenient to remove the film from the battery casings in subsequent processing, effectively ensuring the production efficiency of the battery.
