[0039] Please see Figure 1 and Figure 2This application provides a packaging device, including a first conveyor line 10, a first base tray loading device 20, a pallet loading device 30, a battery cell loading device 40, and a handling device 50. The first conveyor line 10 has a first loading station a1 and a first stacking station a2, and is used to convey a base tray A located at the first loading station a1 to the first stacking station a2. The first base tray loading device 20 is used to provide base tray A to the first loading station a1 of the first conveyor line 10. The pallet loading device 30 is used to provide a pallet B. The battery cell loading device 40 is used to provide battery cells C. The first conveyor line 10, the pallet loading device 30, and the battery cell loading device 40 are arranged around the handling device 50 so that the handling device 50 can stack the pallet B provided by the pallet loading device 30 onto the base tray A located at the first stacking station a2, and can also transfer the battery cells C provided by the battery cell loading device 40 to the pallet B located at the first stacking station a2.

[0040] In actual packaging operations, the aforementioned packaging equipment firstly loads base tray A onto the first loading station a1 of the first conveyor line 10, and the first conveyor line 10 then transports base tray A from the first loading station a1 to the first stacking station a2. Next, the handling device 50 transfers the pallet B provided by the pallet loading device 30 onto the base tray A at the first stacking station a2. Finally, the handling device 50 stacks the battery cells C provided by the battery cell loading device 40 onto the pallet at the first stacking station a2. The process continues until the tray B is filled with battery cells C. Then, the transport device 50 transfers the tray B provided by the tray loading device 30 to the top of the tray B located at the first stacking station a2. Then, the transport device 50 stacks the battery cells C provided by the battery cell loading device 40 onto the top tray B located at the first stacking station a2 until the tray B is filled with battery cells C. This process is repeated until a certain number of trays B are stacked on the bottom tray A located at the first stacking station a2, and each layer of tray B is filled with battery cells C.

[0041] In this way, the above-mentioned packaging equipment can automatically complete the feeding of base tray A, the feeding and stacking of pallet B, and the stacking of battery cell C, thereby realizing the palletizing and packaging of battery cell C, avoiding manual palletizing and packaging, greatly improving the degree of automation and production efficiency.

[0042] In embodiments of this application, the packaging equipment further includes a second conveyor line 60 and a second base tray loading device 70. The second conveyor line 60 has a second loading station a3 and a second stacking station a4. The second base tray loading device 70 is used to provide base trays A to the second loading station a3 of the second conveyor line 60. The second conveyor line 60 is used to transport the base trays A located at the second loading station a3 to the second stacking station a4. The handling device 50 is also used to stack the pallets B provided by the pallet loading device 30 onto the base trays A located at the second stacking station a4. The handling device 50 is also used to transfer the battery cells C provided by the battery cell loading device 40 onto the uppermost pallet B located at the second stacking station a4.

[0043] Thus, in the actual packaging operation, firstly, the second bottom tray feeding device 70 feeds bottom tray A to the second feeding station a3 of the second conveyor line 60, and the second conveyor line 60 transports bottom tray A located at the second feeding station a3 to the second stacking station a4; then, the handling device 50 transfers the pallet B provided by the pallet feeding device 30 to the bottom tray A located at the second stacking station a4; then, the handling device 50 stacks the battery cells C provided by the battery cell feeding device 40 onto the topmost pallet B located at the second stacking station a4. The process continues until the tray B is filled with battery cells C. Then, the transport device 50 transfers the tray B provided by the second tray loading device 30 to the top tray B located at the second stacking station a4. Then, the transport device 50 stacks the battery cells A provided by the battery cell loading device 40 onto the top tray B located at the second stacking station a4 until the tray B is filled with battery cells C. This cycle continues until a certain number of trays B are stacked on the bottom tray A located at the second stacking station a4, and each layer of tray B is filled with battery cells C.

[0044] Furthermore, the first conveyor line 10 has two first stacking stations a2, which are located on opposite sides of the first loading station a1 in the second direction X2. The first conveyor line 10 can convey the base tray A located at the first loading station a1 to the two first stacking stations a2 respectively. In this way, the stacking and packaging of the battery C can be completed at both first stacking stations a2.

[0045] It should be noted that the battery cell loading device 40 provides battery cells C of different grades, such as first grade, second grade, and third grade. The handling device 50 transfers the first grade battery cells C provided by the battery cell loading device 40 to pallets B located at one of the first stacking stations a2, transfers the second grade battery cells C to pallets B located at another of the first stacking stations a2, and transfers the third grade battery cells C to pallets B located at the second stacking station a4. This achieves the classification and packaging of battery cells C, that is, battery cells C of the same grade are stacked on different layers of pallets B of the same packaging material.

[0046] It should be noted that the first conveyor line 10 can be a roller conveyor or a belt conveyor, as long as it can transport the bottom tray A of the first loading station a1 to the first stacking station a2, and there is no limitation here. Similarly, the second conveyor line 60 can also be a roller conveyor or a belt conveyor, as long as it can transport the bottom tray A of the second loading station a3 to the second stacking station a4, and there is no limitation here.

[0047] Specifically, in the embodiment, the first conveyor line 10 and the second conveyor line 60 are respectively arranged on both sides of the handling device 50 in the first direction X1. One of the first stacking stations a2, the first loading station a1 and the other first stacking station a2 of the first conveyor line 10 are arranged at intervals along the second direction X2 perpendicular to the first direction X1. The second loading station a3 and the second stacking station a4 of the second conveyor line 60 are arranged at intervals along the second direction X2. The battery cell loading device 40 is arranged on one side of the handling device 50 in the second direction X2, so that the handling device 50 can transfer the battery cell C to the first stacking station a2 and the second stacking station a4, which helps to save battery cell handling time.

[0048] Furthermore, one of the first stacking stations a2 and the second stacking station a4 are opposite each other in the first direction X1, and the first loading station a1 and the second loading station a3 are opposite each other in the first direction X1. The other second stacking station a4 is opposite to the pallet loading device 30 in the first direction X1. Thus, the handling device 50 facilitates the transfer of pallet B provided by the pallet loading device 30 to the two first stacking stations a2 and the second stacking station a4, thereby saving pallet handling time.

[0049] Specifically, in this embodiment, the packaging equipment further includes a first unloading conveyor line 81 and a second unloading conveyor line 82. The first unloading conveyor line 81 is arranged on the side of the first stacking station a2 away from the handling device 50, and is used to convey the packaging materials located at the first stacking station a2 downstream. The packaging materials refer to the entire assembly formed by the base tray A and the various pallets B stacked on the base tray A (each pallet B is filled with battery cells C). When the first unloading conveyor line 81 conveys the packaging materials to the downstream end, the packaging materials on the first unloading conveyor line 81 are transferred to the designated position using an AGV or a manual forklift (i.e., the packaging materials are unloaded from the first stacking station a2).

[0050] The second unloading conveyor line 82 is located on the side of the second stacking station a4 away from the handling device 50, and is used to transport the packaging materials located at the second stacking station a4 downstream. The packaging materials refer to the entire assembly formed by the base tray A and the various pallets B stacked on the base tray A (each pallet B is filled with battery cells C). When the second unloading conveyor line 82 transports the packaging materials to the downstream end, the packaging materials on the second unloading conveyor line 82 are transferred to the designated position using AGVs or manual forklifts (i.e., the packaging materials are unloaded from the second stacking station a4).

[0051] It should be noted that the first unloading conveyor line 81 can use a roller conveyor, or other types of conveyors, such as belt conveyors, as long as they can transport the packaging materials from the first stacking station a2 downstream. No limitation is made here. Similarly, the second unloading conveyor line 82 can use a roller conveyor, or other types of conveyors, such as belt conveyors, as long as they can transport the packaging materials from the second stacking station a4 downstream. No limitation is made here.

[0052] In a specific embodiment, the packaging equipment also includes a defective cell buffer platform 41, which is arranged on the side of the pallet loading device 30 away from the second loading station a3. The handling device 50 can also transfer defective cells provided by the cell loading device 40 to the defective cell buffer platform 41, thereby preventing defective cells from being transferred to the pallet B of the first stacking station a2 or the second stacking station a4 for stacking and packaging.

[0053] In a specific embodiment, the packaging equipment also includes a defective pallet buffer platform 42, which is arranged on the side of the handling device 50 away from the cell loading device 40. The handling device 50 can also transfer defective pallets provided by the pallet loading device 30 to the defective pallet buffer platform 42, thereby preventing defective pallets from being transferred to the first stacking station a2 or the second stacking station a4 for stacking and packaging.

[0054] In the embodiments of this application, the pallet loading device 30 includes a pallet conveyor line 31 and a pallet positioning mechanism 32. The aforementioned second conveyor line 60 also has a third loading station a5, and the pallet loading device 30 is connected to the third loading station a5 of the second conveyor line 60. Pallets are stacked on the base tray A and loaded onto the pallet conveyor line 31 using an AGV or a manual forklift. The pallet conveyor line 31 is used to transport the base tray A and each layer of pallets B stacked on the base tray A as a whole to the third loading station a5 of the second conveyor line 60. The handling device 50 is used to transfer each layer of pallets B on the base tray A of the third loading station a5 one by one to the first stacking station a2 or the second stacking station a4.

[0055] The pallet positioning mechanism 32 is arranged corresponding to the pallet conveyor line 31 and is used to position each layer of pallets B on the pallet conveyor line 31 so that each layer of pallets B is stacked in the center of the base tray A, so as to avoid the handling device 50 being unable to accurately grasp the pallet B due to the position of the pallet B on the base tray A being offset.

[0056] Specifically, in this embodiment, the pallet positioning mechanism 32 includes a mounting frame 321 and multiple positioning units 324 mounted on the mounting frame 321. Each positioning unit 324 is arranged around the layers of pallets B on the base tray A on the pallet conveyor line 31 and can be controlled to move closer to or further away from each other. Thus, when an AGV or manual forklift loads the base tray A and the multiple layers of pallets B stacked on the base tray A as a whole onto the pallet conveyor line 31, the positioning units 324 are controlled to move closer to each other until they contact the perimeter of the layers of pallets B on the base tray A, until the layers of pallets B are pushed to a designated position (i.e., the center position of the base tray A), thereby achieving the positioning of the layers of pallets B on the base tray A. Then, the positioning units 324 are controlled to move further away from each other and separate from the layers of pallets B. Then, the pallet conveyor line 31 transports the base tray A and the layers of pallets B on the base tray A as a whole to the third loading station a5 of the second conveyor line 60.

[0057] After all the pallets B on the bottom tray A of the third loading station a5 have been removed by the handling device 50, the second conveyor line 60 transports the bottom tray A of the third loading station a5 to the second loading station a3 or the second stacking station a4. In this way, using the bottom tray A loaded by the pallet conveyor line 31 to receive the pallet A and the battery cell C at the second stacking station a4 improves material transfer efficiency, avoids the need for manual removal of the bottom tray A from the third loading station a5, and further enhances the level of automation.

[0058] Furthermore, the pallet positioning mechanism 32 also includes two motion frames 322 and a drive unit 323. The two motion frames 322 are movably connected to the mounting frame 321 along a second direction X2, and each motion frame 322 has two positioning units 324 spaced apart along a first direction X1. The drive unit 323 is mounted on the mounting frame 321 and is drively connected to the two motion frames 322, so that the drive unit 323 can drive the two motion frames 322 to move closer or further away from each other, thereby causing the two positioning units 324 on one motion frame 322 to move closer or further away from each other than the two positioning units 324 on the other motion frame 322.

[0059] Thus, when an AGV or manual forklift loads a base tray A and multiple stacked pallets B on it onto the pallet conveyor line 31 as a whole, the base tray A and the multiple stacked pallets B are positioned between four positioning units 324. The drive unit 323 drives two moving frames 322 to move closer to each other, thereby causing the four positioning units 324 to gradually approach each layer of pallets B until all four positioning units 324 are in contact with each layer of pallets B, positioning each layer of pallets B at the center of the base tray A. Then, the drive unit 323 drives the two moving frames 322 to move away from each other, thereby causing the four positioning units 324 to gradually move away from each layer of pallets B. Finally, the pallet conveyor line 31 transports the base tray A and the multiple stacked pallets B on it as a whole to the third loading station a5 of the second conveyor line 60.

[0060] It should be noted that the drive unit 323 can be a motor and a belt drive mechanism, as long as it can drive the two motion frames 322 to drive the four positioning units 324 to position each layer of tray A. No limitation is made here.

[0061] Specifically, each positioning unit 324 includes a positioning frame 3241 and a plurality of positioning rollers 3243 mounted on the positioning frame 3241. The positioning frame 3241 is mounted on a moving frame 322, and each positioning roller 3243 is rotatably connected to the positioning frame 3241. The plurality of positioning rollers 3243 are arranged sequentially in a vertical direction. Thus, when the two moving frames 322 move closer to each other, each positioning roller 3243 abuts against each layer of tray B, thereby achieving positioning of each layer of tray B and avoiding scratching the tray B. Furthermore, this vertical direction is perpendicular to the aforementioned first direction X1 and second direction X2.

[0062] It should be noted that during the process of the handling device 50 stacking battery cells C onto pallets B, especially when multiple layers of pallets B are stacked on the bottom tray A, pallets B are prone to warping or displacement, making it impossible to accurately stack battery cells A onto the topmost pallet B. To avoid the above defects, in some embodiments, the packaging equipment also includes a pressing device 90, which is arranged corresponding to the first stacking station a2 and the second stacking station a3. This pressing device 90 is used to press the layers of pallets B stacked on the bottom tray A located at the first stacking station a2 or the second stacking station a3, ensuring that each layer of pallets B is stacked in place, preventing warping or displacement, and thus ensuring that the handling device 50 can accurately stack battery cells C onto pallets B. Specifically, there are three pressing devices 90, arranged at the two first stacking stations a2 and one second stacking station a3. The structures of the three pressing devices 90 are similar, so the following description uses one of the pressing devices 90 as an example.

[0063] Please see Figures 4 to 6 Specifically, in this embodiment, the pressing device 90 includes a fixed frame 91, a lifting frame 92, a driving member 93, and two pressure plates 97. The lifting frame 92 is vertically connected to the fixed frame 91. The two pressure plates 97 are spaced apart from each other on the lifting frame 92, so that the two pressure plates 97 can move up and down with the lifting frame 92. The driving member 93 is mounted on the fixed frame 91 and is drively connected to the lifting frame 92, so that the driving member 93 can drive the lifting frame 92 to move up and down relative to the fixed frame 91. Furthermore, the two pressure plates 97 can be controlled to move closer to or further away from each other.

[0064] Thus, the packaging process at the first stacking station a2 is described below as an example: When it is necessary to press each layer of pallets B together, firstly, the two pressure plates 97 are controlled to move closer to each other, so that the two pressure plates 97 and the opposite edge areas of the uppermost pallet B below them are vertically opposite each other; then, the drive unit 93 drives the lifting frame 92 to descend relative to the fixed frame 91, thereby driving the two pressure plates 97 to descend until the two pressure plates 97 respectively abut against the opposite edge areas of the uppermost pallet B, thereby pressing each layer of pallets B tightly onto the bottom support A, thereby achieving the pressing of each layer of pallets B, avoiding the warping or displacement of pallets B, and ensuring that the handling device 50 can accurately stack the battery cells C onto the uppermost pallet B.

[0065] Once the top pallet B is full of battery cells C, firstly, the drive unit 93 drives the lifting frame 92 to rise relative to the fixed frame 91, thereby causing the two pressure plates 97 to rise and separate from the top pallet B. Then, the two pressure plates 97 are controlled to move away from each other, so that the two pressure plates 97 leave the space above the top pallet B, allowing the two pressure plates 97 to avoid the stacking action of the transport device 50. Next, the transport device 50 transfers the pallet B at the third loading station a5 to the top pallet B at the first stacking station a2. Then, the two pressure plates 97 are controlled to move closer to each other until the edges of the two pressure plates 97 and the opposite ends of the top pallet B below them are vertically aligned. Next, the drive unit 93 drives the lifting frame 92 to descend relative to the fixed frame 91, thereby causing the two pressure plates 97 to descend until the two pressure plates 97 abut against the opposite ends of the top pallet B. Finally, the transport device 50 stacks the battery cells C onto the top pallet B. This process is repeated until a certain number of trays B are stacked on the bottom tray A at the first stacking station a2, and each tray B is filled with battery cells C.

[0066] Specifically, the pressing device 90 also includes a transmission mechanism, which comprises a rotating shaft 94, a first driving pulley 951, a first driven pulley 952, and a first transmission belt 953. The rotating shaft 94 is rotatably connected to the fixed frame 91. The driving member 93 is drively connected to the rotating shaft 94, enabling the driving member 93 to drive the rotating shaft 94 to rotate. The first driving pulley 951 is mounted on the rotating shaft 94, and the first driven pulley 952 is mounted on the fixed frame 91, with the first driving pulley 951 and the first driven pulley 952 spaced apart in the vertical direction. The first transmission belt 953 is tensioned and sleeved between the first driving pulley 951 and the first driven pulley 952, enabling the first driving pulley 951 to drive the first transmission belt 953 to move between the first driving pulley 951 and the first driven pulley 952 (i.e., move in the vertical direction). The first transmission belt 953 is connected to the lifting frame 92, enabling the first transmission belt 953 to drive the lifting frame 92 to rise and fall relative to the fixed frame 91. Alternatively, the drive unit 93 may be an electric motor.

[0067] Thus, when the driving component 93 drives the rotating shaft 94 to rotate, the rotating shaft 94 drives the first driving pulley 951 to rotate, the first driving pulley 951 then drives the first transmission belt 953 to move between the first driving pulley 951 and the first driven pulley 952, the first transmission belt 953 then drives the lifting frame 92 to rise or fall, and the lifting frame 92 then drives the two pressure plates 97 to rise or fall.

[0068] Furthermore, the transmission mechanism also includes a second driving pulley 961, a second driven pulley 962, and a second transmission belt 963. The second driving pulley 961 is mounted on the output shaft of the drive member 93, thereby enabling the drive member 93 to drive the second driving pulley 961 to rotate. The second driven pulley 962 is mounted on the rotating shaft 94, thereby enabling the second driven pulley 962 to drive the rotating shaft 94 to rotate. The second transmission belt 963 is tensioned and sleeved between the second driving pulley 961 and the second driven pulley 962, so that the second driving pulley 961 can drive the second driven pulley 962 to rotate via the second transmission belt 963.

[0069] Thus, when the driving component 93 drives the second driving pulley 961 to rotate, the second driving pulley 961 drives the second driven pulley 962 to rotate via the second transmission belt 963. The second driven pulley 962 then drives the rotating shaft 94 to rotate, and the rotating shaft 94 then drives the first driving pulley 951 to rotate. The first driving pulley 951 then drives the first transmission belt 953 to move between the first driving pulley 951 and the first driven pulley 952. The first transmission belt 953 then drives the lifting frame 92 to rise or fall, and the lifting frame 92 then drives the two pressure plates 97 to rise or fall.

[0070] It should be noted that the transmission mechanism is not limited to belt drive mechanism. In other embodiments, the transmission mechanism can also be chain drive mechanism, lead screw drive mechanism, gear and rack drive mechanism, as long as it can convert the rotational motion output by the drive component 93 into the lifting motion of the lifting frame 92. There is no limitation here.

[0071] In a specific embodiment, the pressing device 90 further includes a translation mechanism disposed between each pressure plate 97 and the lifting frame 92. Each translation mechanism includes a translation seat 98 and a translation drive 99. The translation seat 98 is movably connected to the lifting frame 92, and the translation drive 99 is mounted on the lifting frame 92 and drivenly connected to the translation seat 98, so that the translation drive 99 can drive the translation seat 98 to move relative to the lifting frame 92. The pressure plate 97 is mounted on the translation seat 98, so that the translation seat 98 can drive the pressure plate 97 thereon to move closer to or away from another pressure plate 97. In this way, the two translation drive 99 can drive the two translation seats 98 to move closer to or away from each other, and the two translation seats 98 respectively drive the two pressure plates 97 to move closer to or away from each other. Optionally, the translation drive 99 can be a cylinder.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
