DETAILED DESCRIPTION

[0034] The embodiments of the present application are described in detail below in conjunction with the drawings in the embodiments of the present application.

[0035] Example

[0036] Please refer to Figures 2 - 14 The present embodiment provides a battery stacking system, including a main mounting frame 2, the main mounting frame 2 is provided with a feeding conveyor belt 3, the main mounting frame 2 is provided with a battery pack adsorption and rotation mechanism 4 at the discharge end of the feeding conveyor belt 3, the battery pack adsorption and rotation mechanism 4 includes a rotation turntable 41 rotatably arranged on the main mounting frame 2, and a plurality of suction cups 42 are evenly spaced along the circumference of the rotation turntable 41; the main mounting frame 2 is provided with a battery pack vertical material conveying mechanism 5 and a battery pack discharge mechanism 6, the rotation turntable 41 is located between the battery pack vertical material conveying mechanism 5 and the feeding conveyor belt 3, and the battery pack discharge mechanism 6 is located at the discharge end of the battery pack vertical material conveying mechanism 5.

[0037] The feeding conveyor belt 3 of this embodiment adopts the existing product. When in use, the battery groups (a battery group in this embodiment is composed of four batteries 1 arranged side by side and packaged with plastic film) are placed on the feeding conveyor belt 3 one by one, and each battery group is transported to the position of the rotation turntable 41 in turn through the feeding conveyor belt 3. Each suction cup 42 of the rotation turntable 41 is used to adsorb the battery group, and one suction cup 42 adsorbs one battery group. The rotation turntable 41 rotates the adsorbed battery group and drives it to the position of the battery group vertical material conveying mechanism 5. The battery group falls off the rotation turntable 41 and is transported to the position of the battery group discharging mechanism 6 through the battery group vertical material conveying mechanism 5. After multiple battery groups are stacked into a set at the position of the battery group discharging mechanism 6, the stacked batteries are transported out through the battery group discharging mechanism 6. The battery group discharging mechanism 6 is connected to the existing packaging machine working position, and a set of batteries transported out can be packaged by the packaging machine working position.

[0038] like Figures 5 - 9 As shown, in some embodiments, the battery pack adsorption rotation mechanism 4 further includes a first drive motor 44 provided on the main mounting frame 2, and the first drive motor 44 is transmission-connected to a first gear box 45; the main mounting frame 2 is rotationally provided with a first rotating shaft 46, and the rotation turntable 41 is fixedly sleeved on the first rotating shaft 46; the first rotating shaft 46 and the power output end of the first gear box 45 are transmission-connected via a first belt 47. The first drive motor 44 of this embodiment is used to drive the first rotating shaft 46 to rotate, wherein the first drive motor 44 is connected to the first gear box 45 for transmission, and the first gear box 45 and the first rotating shaft 46 are transmitted via a first belt 47, so that the first rotating shaft 46 can be driven to rotate by the first drive motor 44, and the rotating first rotating shaft 46 can drive the rotation turntable 41 to rotate a set angle.

[0039] In some embodiments, the battery pack adsorption and posture conversion mechanism 4 further includes a negative pressure plate 48 fixed to the main mounting bracket 2. The negative pressure plate 48 is coaxial with the posture conversion turntable 41 and abuts against the posture conversion turntable 41. The negative pressure plate 48 is provided with negative pressure suction holes 481 and pressure equalizing holes 482. On the side of the negative pressure plate 48 close to the posture conversion turntable 41, there are an arc-shaped negative pressure suction groove 483 and a pressure equalizing groove 484. The negative pressure suction holes 481 are communicated with the negative pressure suction groove 483, and the pressure equalizing holes 482 are communicated with the pressure equalizing groove 484.

[0040] Along its circumference, the posture conversion turntable 41 is evenly spaced with a plurality of negative pressure suction channels 485. On the side of the posture conversion turntable 41 close to the negative pressure plate 48, there are a plurality of negative pressure suction connection holes 486. The negative pressure suction channels 485, the suction cups 42 and the negative pressure suction connection holes 486 correspond to each other one by one. One end of the negative pressure suction channel 485 is communicated with the suction cup 42, and the other end of the negative pressure suction channel 485 is communicated with the negative pressure suction connection hole 486. Some of the negative pressure suction connection holes 486 are communicated with the negative pressure suction groove 483 and the pressure equalizing groove 484.

[0041] In this embodiment, only some of the negative pressure suction holes 481 are communicated with the negative pressure suction groove 483. During use, the negative pressure suction holes 481 of the negative pressure plate 48 are used to connect the suction pipeline of the negative pressure device. By the negative pressure device, negative pressure is generated inside the negative pressure suction groove 483. At this time, negative pressure will be generated inside several negative pressure suction channels 485 communicated with the negative pressure suction groove 483. At this time, the suction cups 42 corresponding to these negative pressure suction channels 485 can generate negative pressure, that is, they have adsorption ability, and the other suction cups 42 are not communicated with the negative pressure suction groove 483 and do not have adsorption ability.

[0042] When the feeding conveyor belt 3 conveys the battery packs one by one to the suction cups 42 at the top position of the posture conversion turntable 41, after one suction cup 42 adsorbs a battery pack (the battery pack is in a horizontally placed posture), then the first driving motor 44 drives the posture conversion turntable 41 according to Figure 5Rotate clockwise by a certain angle as shown. The next empty suction cup 42 moves to the top position of the rotation posture turntable 41 to adsorb the next battery pack. The suction cup 42 that has adsorbed the battery pack rotates clockwise downward until the rotation posture turntable 41 rotates to drive the battery pack to the rightmost position. At this time, the battery pack moves from the initial horizontally placed posture to a vertically placed posture. At the same time, the negative pressure suction connection hole 486 corresponding to the suction cup 42 that adsorbs the battery pack moves to the position of the pressure equalizing groove 484 and communicates with the pressure equalizing groove 484. Since the pressure equalizing groove 484 communicates with the external air through the pressure equalizing hole 482, at this time, the negative pressure suction connection hole 486 communicates with the external air and does not have negative pressure ability. After the suction cup 42 loses negative pressure ability, the battery pack it adsorbs detaches and is taken away by the battery pack vertical material conveying mechanism 5. In this way, the battery pack adsorbed and rotated by the battery pack adsorption and rotation mechanism 4 is cycled through the feeding conveyor belt 3, converted from a horizontal state to a vertically placed state and conveyed to the battery pack vertical material conveying mechanism 5.

[0043] Optionally, in order to improve the stability of the battery pack after being adsorbed on the suction cup 42, a plurality of material placing steps 43 are provided along the circumferential direction on the circumferential side of the rotation posture turntable 41 in this embodiment. The material placing steps 43 correspond to the suction cups 42 one by one. After the battery pack is adsorbed by the suction cup 42, it can abut against the material placing steps 43 during the rotation process of the battery pack, improving the stability of the battery pack during the rotation posture process.

[0044] As Figures 10 - 13 As shown, in some embodiments, the battery pack vertical material conveying mechanism 5 includes two vertical material conveyor belts 51 relatively arranged on the main mounting frame 2, and the conveying surfaces of the two vertical material conveyor belts 51 face each other; a cushion plate 53 is provided between the two vertical material conveyor belts 51 on the main mounting frame 2, and the rotation posture turntable 41 is located between the two vertical material conveyor belts 51; a plurality of vertical material blocking blocks 54 are evenly spaced along the conveying direction on the outer side wall of the vertical material conveyor belt 51. In this embodiment, a second driving motor 52 is provided on the main mounting frame 2 to drive the two vertical material conveyor belts 51 to rotate, and the second driving motor 52 and the two vertical material conveyor belts 51 can be driven through a plurality of gears.

[0045] A buffer limit brush 55 is provided above the two vertical material conveyor belts 51 on the main mounting frame 2, and the buffer limit brush 55 is located between the two vertical material conveyor belts 51 and at their discharge end. A top material cylinder 56 is provided at the discharge end of the two vertical material conveyor belts 51 on the main mounting frame 2, and a top material plate 57 is provided at the telescopic end of the top material cylinder 56, and the top material plate 57 is located between the vertical material conveyor belts 51.

[0046] During actual use, each battery pack is conveyed between the two vertical material conveyor belts 51 by rotating the rotation position turntable 41. At this time, after the battery pack falls off the suction cup 42, it drops onto the top of the backing plate 53. At the same time, both sides of the battery pack are respectively located between two adjacent vertical material stoppers 54. The vertical material stoppers 54 limit the battery pack to prevent it from tipping over and keep the battery pack in a vertical state. The two vertical material conveyor belts 51 rotate and convey each battery pack to the position of the buffer limit brush 55 through the vertical material stoppers 54. The battery pack can be stuck at the bottom of the buffer limit brush 55 in a vertical state. At the same time, one side of the battery pack can abut against the pushing plate 57 at the telescopic end of the top pushing cylinder 56. By abutting the pushing plate 57 against the battery pack, it can prevent the battery pack from tipping over and improve its stability during movement. As the vertical material conveyor belts 51 continuously convey the battery packs, the battery packs in the front are continuously pushed forward. At the same time, the telescopic end of the top pushing cylinder 56 continuously shortens, and multiple battery packs are stacked together and move towards the battery pack discharging mechanism 6 side.

[0047] As Figure 10 and Figure 14 shown, in some embodiments, the battery pack discharging mechanism 6 includes a battery pack discharging conveyor belt 61 provided on the main mounting frame 2. A plurality of discharging push plates 62 are evenly spaced along the conveying direction on the outer side wall of the battery pack discharging conveyor belt 61. The discharging end of the battery pack vertical conveying mechanism 5 is located between two adjacent discharging push plates 62. The main mounting frame 2 of this embodiment is provided with a third driving motor 63 for driving the battery pack discharging conveyor belt 61 to rotate. As Figure 14 shown, the third driving motor 63 and the battery pack discharging conveyor belt 61 are connected by belt drive.

[0048] The stacked battery packs are located between two adjacent discharging push plates 62. When a certain number (six battery packs are stacked as a set in this embodiment) of battery packs move to align with the discharging push plates 62, that is, when the six stacked battery packs move to align with the discharging push plates 62, the third driving motor 63 is started to drive the battery pack discharging conveyor belt 61 to rotate. At this time, the six stacked battery packs are pushed and conveyed out by the discharging push plates 62, and the battery packs can be pushed to the working position of the subsequent packaging machine for packaging.

[0049] In this way, the battery stacking system provided by this application can stack multiple battery packs into a set and transfer them to the working position of the subsequent packaging machine for packaging. During the transmission process of the battery packs, they are fixed stably and not easy to fall off, improving the feeding and discharging efficiency of the battery packs, improving the stability of the system, and further improving the working efficiency and production capacity of the battery packaging production line, reducing the equipment operation and maintenance cost and the labor cost. Optionally, this embodiment can be automatically controlled through a PLC control system, and each electronic device is connected to the PLC control system for control.

[0050] As Figures 2 - 3As shown, in some embodiments, first limiting baffles 7 are provided on both sides of the feeding conveyor belt 3 of the main mounting frame 2. In the present invention, by providing the first limiting baffles 7, during the process of the battery pack being conveyed on the top of the feeding conveyor belt 3, the battery pack is located between the two first limiting baffles 7, and the two first limiting baffles 7 are used to limit the battery pack, facilitating its stable conveyance to the feeding end position of the battery pack adsorption and posture conversion mechanism 4.

[0051] As Figures 2 - 5 shown, in some embodiments, an auxiliary conveying mechanism 8 is provided between the discharging end of the feeding conveyor belt 3 and the posture conversion turntable 41. The auxiliary conveying mechanism 8 includes a fourth driving motor 81 provided on the main mounting frame 2, a first auxiliary mounting roller 82 rotatably provided on the main mounting frame 2, and a second auxiliary mounting roller 83. The number of the second auxiliary mounting rollers 83 is two and they are respectively located on both sides of the posture conversion turntable 41; auxiliary conveyor belts 84 are wound between the two second auxiliary mounting rollers 83 and the first auxiliary mounting roller 82; the fourth driving motor 81 is in transmission connection with the first auxiliary mounting roller 82 through a second belt 85.

[0052] Since the posture conversion turntable 41 is of a circular structure, it is not easy for the feeding conveyor belt 3 to directly convey the battery pack to the top position of the posture conversion turntable 41. By providing the auxiliary conveying mechanism 8, the feeding conveyor belt 3 can directly convey the battery pack to the feeding end of the auxiliary conveyor belt 84, and the fourth driving motor 81 is used to drive the auxiliary conveyor belt 84 to rotate. In this way, the battery pack can be driven by the auxiliary conveyor belt 84 to move to the top position of the posture conversion turntable 41, which is convenient for adsorbing the battery pack.

[0053] In addition, unless otherwise clearly specified or limited, in the embodiments of the present application, if the terms "mounting" and "connection" are used, they should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. If the orientation terms such as "upper", "lower", "left", "right", "inner", "outer", "side", etc. appear, they are only references to the direction of the attached drawings or the orientation in which the product is usually placed during use, and are only for clearly describing the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as a limitation to the present application. The terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance; "a plurality" means at least two. In the embodiments of the present application, the limitations on relative position relationships such as parallel, perpendicular, and alignment mentioned are all for the current process level and are not absolutely strict limitations. A small deviation is allowed, and approximate parallel, approximate perpendicular, approximate alignment, etc. are all acceptable. For example, if A is parallel to B, it means that A is parallel or approximately parallel to B, and the included angle between A and B can be between 0 degrees and 10 degrees.

[0054] The above are only some embodiments and implementation manners of the present application. The protection scope of the present application is not limited thereto. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other, and any combination of features in different embodiments is also within the protection scope of the present application.
