Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a material preparation mechanism for pouch battery stacking accessories. Background Technology

[0002] Soft-pack batteries are composed of stacked individual soft-pack cells, with the stacking direction of the individual cells defining the height of the soft-pack battery. End plates are positioned at both ends of the soft-pack battery along its height, and heat insulation plates are placed between adjacent individual soft-pack cells. Conventionally, end plates and heat insulation plates are stacked for efficient material preparation. A robotic arm or other actuator, along with suction cups or grippers, grasps the end plates or heat insulation plates at their stacking positions for use in stacking the soft-pack batteries. However, as the upper end plates or heat insulation plates are grasped, the stacking height decreases. In the next round of material retrieval, the suction cups or grippers controlled by the robotic arm need to adjust their vertical position downwards to grasp the lower end plates or heat insulation plates. This increases the control difficulty of the robotic arm and other actuators. Since the stacking of end plates and heat insulation plates may be in a loose state, the downward adjustment distance of the suction cups or grippers in the vertical direction during the next round of material retrieval has some uncertainty, leading to difficulties in loading the end plates and heat insulation plates.

[0028] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Please refer to Figures 1 to 9 A material preparation mechanism for stacking pouch batteries, used for feeding end plate a and heat insulation plate b. For example... Figure 1 As shown, the parts preparation mechanism 1 includes a frame 11, a gantry double drive structure 12 is configured on the frame 11, a loading area 111 and a unloading area 112 are configured on the frame 11, and a gripping structure 13 is configured on the gantry double drive structure 12. The gripping structure 13 can reciprocate between the loading area 111 and the unloading area 112 under the action of the gantry double drive structure 12. The loading area 111 here can store a large number of end plates a and heat insulation plates b for stacking soft-pack batteries. The gripping structure 13, together with the gantry dual-drive structure 12, transfers the end plates a and heat insulation plates b in the loading area 111 to the unloading area 112 as needed, completing the preparation of end plates a and heat insulation plates b, so that the transfer mechanism (not shown in the figure) can accurately grip end plates a and heat insulation plates b. By transferring end plates a and heat insulation plates b between the loading area 111 and the unloading area 112, the loading efficiency of the transfer mechanism can be improved. Specifically, the end plates a and heat insulation plates b in the unloading area 112 are the single transfer quantity of the transfer mechanism. There is no stacking in the loading area 111. Therefore, the spatial position of the transfer mechanism when picking up materials in the unloading area 112 is fixed, which reduces the operation difficulty of the transfer mechanism and helps to improve the operation accuracy of the transfer mechanism and stabilize the production cycle. Moreover, the loading operation of the transfer mechanism can be unaffected when replenishing end plates a and heat insulation plates b in the loading area 111.

[0032] In this embodiment, the transfer mechanism can be an actuator such as a robotic arm combined with a suction cup or gripper, which is existing technology. In use, the transfer mechanism transfers the end plate a and the heat insulation plate b on the accessory preparation mechanism 1 to the battery stacking station for stacking.

[0033] like Figure 1 and Figure 3As shown, the loading area 111 is equipped with a first slide plate 14 that can move relative to the frame 11 to approach or move away from the unloading area 112. The first slide plate 14 is equipped with at least one first pallet 141 and at least one second pallet 142. The first pallet 141 is used to stack end plates a, and the second pallet 142 is used to stack heat insulation plates b. The first pallet 141 is equipped with a first guide rod 1411 for limiting end plates a, and the second pallet 142 is equipped with a second guide rod 1421 for limiting heat insulation plates b. The first guide rod 1411 extends vertically and the first guide rod 1411 and the second guide rod 1421 are parallel.

[0034] In this embodiment, optionally, there are two first trays 141 and two second trays 142. One of the first trays 141 has its lower end plate of the pouch battery stacked on it, while the other first tray 141 has its upper end plate of the pouch battery stacked on it. It should be noted that the difference between the upper and lower end plates is that the inner plane of the upper end plate faces downwards, while the inner plane of the lower end plate faces upwards. Both second trays 142 have heat insulation plates b stacked on them. In this embodiment, there are two types of heat insulation plates b with different thicknesses; therefore, a thicker heat insulation plate is placed on one second tray 142, and a thinner heat insulation plate is placed on the other second tray 142. The first guide rod 1411 is used to maintain the structural stability of the end plate a stacked on the first tray 141, limiting the end plate a at both ends in the length direction and both ends in the width direction; correspondingly, the second guide rod 1421 is used to maintain the structural stability of the heat insulation plate b stacked on the second tray 142, limiting the heat insulation plate b at both ends in the length direction and both ends in the width direction. In some embodiments, since the heat insulation plate b is relatively thin, in order to prevent two adjacent heat insulation plates b from sticking together and causing more than one heat insulation plate b to be grasped at a time, at least a portion of the top of the second guide rod 1421 is provided with a brush 1422, the bristles of the brush 1422 being on the path of the heat insulation plate b moving upward in the vertical direction, so as to separate the heat insulation plate b that is stuck to the lower side of the target heat insulation plate b during the grasping process.

[0035] In some embodiments, such as Figure 3 As shown, a pad strip 143 is disposed on the upper side of the first slide plate 14. The first support plate 141 and the second support plate 142 are both mounted on the first slide plate 14 via the pad strip 143. The pad strip 143 creates a gap between the first slide plate 14 and both the first support plate 141 and the second support plate 142. Detection holes (not shown in the figure) are provided through both the first support plate 141 and the second support plate 142. A photoelectric sensing component (not shown in the figure) is installed within this gap to detect the presence or absence of end plate a and heat insulation plate b through the detection hole, determining whether end plate a is present on the first support plate 141 and whether heat insulation plate b is present on the second support plate 142. Optionally, the photoelectric sensing component is a photoelectric sensor.

[0036] like Figure 2 As shown, the unloading area 112 is equipped with a second sliding plate 15, which can move relative to the frame 11 to approach or move away from the loading area 111, that is, to approach or move away from the transfer mechanism; a third pallet 151 is equipped on the second sliding plate 15 for placing the end plate a or the heat insulation plate b; a first limiting surface and a second limiting surface are equipped on the third pallet 151, both of which are perpendicular to the third pallet 151; a first pressing block 1513 corresponding to the first limiting surface and a second pressing block 1514 corresponding to the second limiting surface are equipped on the third pallet 151, the first pressing block 1513 can approach or move away from the first limiting surface, and the second pressing block 1514 can approach or move away from the second limiting surface. The end plate a or the heat insulation plate b is placed within the area defined by the first limiting surface, the first pressing block 1513, the second limiting surface, and the second pressing block 1514. In this embodiment, as shown... Figure 4 As shown, the structure on the frame 11, consisting of a second sliding plate 15 and a third support plate 151, consists of two sets. One set is used to support the end plate a, and the other set is used to support the heat insulation plate b. Of course, in another embodiment, it can also be a single set, with the end plate a and the heat insulation plate b placed on the same third support plate 151.

[0037] like Figure 4 The diagram shows one configuration of the second sliding plate 15 and the third support plate 151, used to support end plate a. Specifically, the third support plate 151 is mounted on the second sliding plate 15 via a column 152. A first limiting block 1511 is provided at one end of the end plate a along its length, with a first limiting surface on the side of the first limiting block 1511 facing the end plate a. A second limiting block 1512 is provided at one end of the end plate a along its width, with a second limiting surface on the side of the second limiting block 1512 facing the end plate a. Both the first limiting block 1511 and the second limiting block 1512 are fixedly connected to the third support plate 151. Both the first limiting surface and the second limiting surface are reference surfaces, working in conjunction with the first pressing block 1513 and the second pressing block 1514 to limit the end plate a. In this embodiment, both the first pressing block 1513 and the second pressing block 1514 are driven by cylinders mounted on the third support plate 151.

[0038] like Figure 7 As shown, this is another configuration of the second sliding plate 15 and the third support plate 151, used to support the heat insulation plate b. Figure 6Unlike the bearing end plate a shown, the third support plate 151 supporting the heat insulation plate b has two placement stations for the heat insulation plate b, corresponding to the assembly conditions of the thin and thick heat insulation plates b in this embodiment. The rest of the structure is the same and will not be described again here. Of course, it is also possible to have two placement stations on the third support plate 151 when the specifications of the heat insulation plates b are the same.

[0039] In this embodiment, optionally, the first slide plate 14 and the second slide plate 15 are both slidably mounted on the frame 11 via a slide rail slider assembly, and the frame 11 is correspondingly provided with rodless cylinders for driving the first slide plate 14 and the second slide plate 15.

[0040] like Figure 6 As shown, the gripping structure 13 includes an adapter frame 131 and a first fixing plate 132. The adapter frame 131 is assembled on the gantry dual-drive structure 12. A first guide shaft 1321 is disposed on the first fixing plate 132. The first guide shaft 1321 extends vertically and passes through the adapter frame 131 and is slidably connected to it. A driving component 133 for driving the first fixing plate 132 to move vertically is disposed on the adapter frame 131. A first gripping module 134 is disposed on the first fixing plate 132. In this embodiment, there are two first guide shafts 1321, which are arranged in parallel. The top ends of the two first guide shafts 1321 are connected by a stabilizing plate 1322 to maintain the structural stability of the two first guide shafts 1321. Optionally, the driving component 133 is an electric cylinder. The first gripping module 134 is used to grip end plate a or heat insulation plate b in the loading area 111 and transfer end plate a or heat insulation plate b to the unloading area 112 under the drive of the gantry dual drive structure 12.

[0041] like Figures 7 to 9As shown, the first gripping module 134 includes a second fixed plate 1341 disposed on the first fixed plate 132. The second fixed plate 1341 is equipped with a first suction cup 1342 and a first pressing assembly 1343. The first pressing assembly 1343 includes a first pressing shaft 13431, which extends vertically and passes through the second fixed plate 1341 and is slidably connected to it. A first limiting block 13433 is disposed at the upper end of the first pressing shaft 13431, and a first pressing block 13434 is disposed at the lower end of the first pressing shaft 13431. A first spring 13435 is sleeved on the first pressing shaft 13431 and is pressed between the second fixed plate 1341 and the first pressing block 13434. Under normal conditions, in the vertical direction, the first pressing block 13434 is lower than the first suction cup 1342. In this embodiment, the first pressure shaft 13431 is slidably connected to the second fixed plate 1341 via the first linear bearing 13432, and the first linear bearing 13432 is fixedly connected to the second fixed plate 1341. This can be understood as the first linear bearing 13432 and the second fixed plate 1341 being an integral structure. In this embodiment, the first spring 13435 indirectly abuts against the second fixed plate 1341 via the first linear bearing 13432. In some embodiments, if the inner diameter of the first spring 13435 is larger than the outer diameter of the first linear bearing 13432, that is, when the first spring 13435 is sleeved outside the first linear bearing 13432, then the first spring 13435 directly abuts against the second fixed plate 1341. Here, the first suction cup 1342 is used to adsorb the heat insulation plate b. Since the first pressing block 13434 is lower than the first suction cup 1342 in the vertical direction, during the downward movement of the first gripping module 134 in the vertical direction, the first pressing block 13434 first abuts against the heat insulation plate b. As the gripping structure 13 continues to move downward, the first pressing shaft 13431 moves upward relative to the second fixed plate 1341 under the action of the first pressing block 13434, and the first spring 13435 is compressed. During this process, the first pressing block 13434 can compact the stacked heat insulation plates b so that the uppermost heat insulation plate b will not shift downward significantly when the first suction cup 1342 is in action, ensuring that the first suction cup 1342 can fully fit with the uppermost heat insulation plate b so that the first suction cup 1342 can more reliably adsorb and grip the heat insulation plate b.

[0042] For end plate a, with its inner surface facing upwards (i.e., the lower end plate of the soft-pack battery), it can be gripped by the first suction cup 1342. However, the upper end plate cannot be gripped by the first suction cup 1342 because its outer surface is uneven. Also, due to the greater weight of end plate a, if... Figure 7As shown, the first gripping module 134 also includes two first claw bodies 1345 disposed on the first fixed plate 132, which can move closer or further apart. In this embodiment, the second fixed plate 1341 is assembled to the first fixed plate 132 via two first connecting plates 1344. A gripper cylinder is disposed on the first fixed plate 132, which is located between the first fixed plate 132 and the second fixed plate 1341. The gripper cylinder is used to drive the two first claw bodies 1345 to move closer or further apart. In this embodiment, the second fixed plate 1341 is located between the two first claw bodies 1345. The first claw bodies 1345 can be used to cooperate with the first suction cup 1342 to grip end plate a, or they can be used alone to grip end plate a. When in use, when the first gripping module 134 grips the heat insulation plate b, the two first claws 1345 are kept away from each other to avoid interference. At this time, the heat insulation plate b can be gripped by the first suction cup 1342. When the first gripping module 134 grips the end plate a, it is preferable that the two first claws 1345 cooperate to grip the end plate a.

[0043] In this embodiment, in order to improve the grasping efficiency of the grasping structure 13, such as Figure 6 and Figure 7 As shown, a second gripping module 135 is also configured on the first fixed plate 132. The second gripping module 135 can move closer to or further away from the first gripping module 134. Here, the second gripping module 135 is movably disposed on the first fixed plate 132 to adjust the distance between the second gripping module 135 and the first gripping module 134, thereby adapting to a wider range of material handling environments. Preferably, the second gripping module 135 is used to grip the heat insulation plate b. Since a pouch battery includes two end plates a and several heat insulation plates b during the pouch battery stacking process, the gripping requirements for the heat insulation plates b are higher. Therefore, the cooperation of the first gripping module 134 and the second gripping module 135 can ensure the gripping efficiency of the heat insulation plates b. In some embodiments, such as... Figure 6 As shown, when the inner plane of end plate a is facing upwards, the second gripping module 135 can also be used to grip end plate a.

[0044] Specifically, the second gripping module 135 includes a third fixed plate 1351 movably mounted on the first fixed plate 132. The third fixed plate 1351 is equipped with a second suction cup 1352 and a second pressing assembly 1353. The second pressing assembly 1353 includes a second pressing shaft extending vertically through the third fixed plate 1351 and slidably connected thereto. A second limiting block is disposed at the upper end of the second pressing shaft, and a second pressing block is disposed at the lower end. A second spring is sleeved on the second pressing shaft and presses between the third fixed plate 1351 and the second pressing block. Normally, in the vertical direction, the second pressing block is lower than the second suction cup 1352. In this embodiment, the third fixed plate 1351 is slidably connected to the first fixed plate 132 via a slide rail slider assembly and is driven by a cylinder mounted on the first fixed plate 132 to allow the third fixed plate 1351 to move closer to or further away from the second fixed plate 1341. The second suction cup 1352 has the same structure as the first suction cup 1342, and the second pressing assembly 1353 has the same structure and function as the first pressing assembly 1343. Specifically, the second pressing shaft corresponds to the first pressing shaft 13431, the second spring corresponds to the first spring 13435, and the second pressing block corresponds to the first pressing block 13434. Further details will not be provided here.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
