Battery unpacking device

Abstract

This utility model relates to a battery unpacking device, including a bracket, a clamping mechanism, and an elastic pressing mechanism. The elastic pressing mechanism includes an elastic support component and a pressing member, the elastic support component allowing the pressing member to extend and retract relative to the clamping mechanism. During battery unpacking, the battery unpacking device first moves towards the battery pack, and the pressing member elastically contacts the pack before the clamping mechanism contacts the battery. As the battery unpacking device continues to approach the pack, the elastic support component is compressed, providing elastic restoring force to the pressing member. After the clamping mechanism successfully grasps the battery, the battery unpacking device then moves away from the pack to pull the battery from its position in the pack. During this process, the pressing member continues to press against the pack under the action of the elastic support component, thus holding the pack within the casing and preventing the pack from moving with the battery. Therefore, the battery unpacking device effectively prevents the pack from being lifted during unpacking.

Description

Technical Field

[0001] This utility model relates to the field of battery processing equipment technology, and in particular to a battery unpacking device. Background Technology

[0002] During battery manufacturing, assembled batteries undergo packaging for storage and transportation. A common packaging process involves first removing specialized packaging materials from the storage compartment and precisely positioning them inside the packaging box. Then, the battery products are embedded into the pre-set slots within the packaging materials according to a predetermined arrangement, forming stable packaging units. The corresponding unpacking process is the reverse: the individual battery cells are first separated from the packaging materials' slots, and then the packaging materials are removed from the box for recycling.

[0003] When removing the battery from the packaging clip, the battery casing and the packaging clip structure are usually designed with an interference fit to ensure transport stability, resulting in excessive holding force between them. Therefore, in actual operation, the packaging can easily be pulled up along with the battery, which not only affects unpacking efficiency but may also cause packaging deformation and damage to any batteries that are not removed, thereby increasing production costs. Utility Model Content

[0004] Therefore, it is necessary to provide a battery unpacking device that can effectively prevent the packaging material from being lifted up, in order to address the above-mentioned technical problems.

[0005] A battery unpacking device includes a bracket, a clamping mechanism, and an elastic pressing mechanism. The clamping mechanism and the elastic pressing mechanism are both mounted on the bracket, and the elastic pressing mechanism is distributed on at least one side of the clamping mechanism. The elastic pressing mechanism includes an elastic support component and a pressing member. The pressing member is connected to the elastic support component. The elastic support component allows the pressing member to extend and retract relative to the clamping mechanism and can provide an elastic restoring force to the pressing member.

[0006] In one embodiment, multiple clamping mechanisms are provided, and the multiple clamping mechanisms are arranged side by side along a first direction.

[0007] In one embodiment, each of the clamping mechanisms includes two clamping plates, and the two clamping plates are arranged opposite each other along a second direction perpendicular to the first direction.

[0008] In one embodiment, the elastic support assembly includes a base, a guide rod, and an elastic element. The guide rod is slidably mounted on the base, the holding member is fixedly connected to one end of the guide rod, and the elastic element is disposed between the holding member and the base.

[0009] In one embodiment, the elastic element is configured as a spring, which is sleeved on the guide rod and clamped between the base and the holding member.

[0010] In one embodiment, multiple guide rods are provided, and the multiple guide rods are arranged in parallel.

[0011] In one embodiment, the holding member is configured as a pressure plate.

[0012] In one embodiment, multiple elastic pressing mechanisms are provided, with elastic pressing mechanisms provided at both ends of the support along its length and on both sides of the support along its width.

[0013] In one embodiment, the elastic holding mechanism further includes a lifting assembly, the elastic support member is connected to the drive end of the lifting assembly, and the lifting assembly is capable of driving the elastic support assembly and the holding member to move up and down relative to the clamping mechanism.

[0014] In one embodiment, a bottom support mechanism mounted on the bracket is also included. The bottom support mechanism includes a bracket and a drive assembly. The bracket can be moved under the drive assembly to the underside of the clamping mechanism or moved out from the underside of the clamping mechanism.

[0015] The aforementioned battery unpacking device first moves towards the battery pack during unpacking, with the holding member elastically contacting the pack before the clamping mechanism comes into contact with the battery. As the device continues to approach the pack, the elastic support component is compressed, providing elastic restoring force to the holding member. After the clamping mechanism successfully grasps the battery, the device then moves away from the pack to remove the battery from its slot. During this process, the holding member continues to press against the pack under the action of the elastic support component, thus holding the pack within the casing and preventing it from moving with the battery. Therefore, the battery unpacking device effectively prevents the pack from being lifted during unpacking. Attached Figure Description

[0027] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the battery unpacking device 10 includes a bracket 100, a clamping mechanism 200, and an elastic pressing mechanism 300.

[0028] The bracket 100 supports the battery unpacking device 10, and both the clamping mechanism 200 and the elastic pressing mechanism 300 are mounted on the bracket 100. The bracket 100 can be mounted on the moving end of a robotic arm (not shown) so that the battery unpacking device 10 can move as a whole under the drive of the robotic arm. Specifically, a mounting base 110 is provided on the top of the bracket 100, and the mounting base 110 can be connected to the moving end of the robotic arm via threaded fasteners.

[0029] The clamping mechanism 200 is used to clamp the battery. Specifically, the clamping mechanism 200 includes two clamping plates 210 (see...). Figure 3The two clamping plates 210 are arranged opposite each other, and the battery can be clamped between the two clamping plates 210. More specifically, the clamping mechanism 200 generally also includes a clamping drive (not shown in the figure), which can be a gripper cylinder. The clamping drive can drive the two clamping plates 210 to move closer or further apart, thereby clamping or releasing the battery.

[0030] Specifically, in this embodiment, multiple clamping mechanisms 200 are provided, and the multiple clamping mechanisms 200 are arranged side by side along a first direction. The first direction generally refers to the length direction of the bracket 100, that is, the multiple clamping mechanisms 200 are arranged side by side along the length direction of the bracket 100. Each clamping mechanism 200 can grasp a battery, so providing multiple clamping mechanisms 200 enables the battery unpacking device 10 to grasp multiple batteries at once, thereby helping to improve the efficiency of battery unpacking.

[0031] Furthermore, in this embodiment, each clamping mechanism 200 includes two clamping plates 210, and the two clamping plates 210 are arranged opposite each other along a second direction perpendicular to the first direction. The second direction generally refers to the width direction of the bracket 100, that is, when gripping or releasing the battery, the two clamping plates 210 will move closer or further apart along the width direction of the bracket 100. In this way, no space needs to be reserved for the movement of the clamping plates 210 in the arrangement direction of the multiple clamping mechanisms 200, that is, in the length direction of the bracket 100. Therefore, the spacing between two adjacent clamping mechanisms 200 can be set to be smaller, thereby making the structure of the battery unpacking device 10 more compact and better adaptable to the narrow space inside the box.

[0032] The elastic holding mechanism 300 is used to hold the packaging material within the housing during the gripping process of the clamping mechanism 200, thereby preventing the packaging material from being lifted. The elastic holding mechanisms 300 are distributed on at least one side of the clamping mechanism 200. Specifically, in this embodiment, multiple elastic holding mechanisms 300 are provided; elastic holding mechanisms 300 are provided at both ends of the support 100 along its length, and on both sides of the support 100 along its width. Therefore, at least four elastic holding mechanisms 300 are provided, distributed at the four corners of the support 100. Multiple elastic holding mechanisms 300 can distribute the force more evenly on the packaging material when holding it, thus providing a better holding effect.

[0033] Please refer to the following: Figure 3 and Figure 4 The elastic holding mechanism 300 includes an elastic support assembly 310 and a holding member 320. The holding member 320 is connected to the elastic support assembly 310, and the elastic support assembly 310 allows the holding member 320 to extend and retract relative to the clamping mechanism 200 and can provide an elastic restoring force to the holding member 320.

[0034] The extension and retraction direction of the pressing member 320 is consistent with the movement direction of the clamping mechanism 200 when it grasps the battery, generally referring to the vertical direction. The pressing member 320 is used to directly contact the packaging material and perform a pressing function. Specifically, in this embodiment, the pressing member 320 is set as a pressure plate. The contact area between the pressure plate and the packaging material is large, so it is more stable when pressing the packaging material. Of course, in other embodiments, the pressing member 320 can also be set as a rod or other shapes.

[0035] During battery unpacking, the battery unpacking device 10 is first moved towards the battery pack (generally vertically), allowing the holding member 320 to elastically contact the pack before the clamping mechanism 200 contacts the battery. Next, the battery unpacking device 10 continues to approach the pack until the clamping mechanism 200 successfully grasps the battery. During this process, the holding member 320 remains in place, and the elastic support component 310 is gradually compressed, providing elastic restoring force to the holding member 320. After the clamping mechanism 200 successfully grasps the battery, the battery unpacking device 10 is then moved away from the pack to pull the battery from its position within the pack. During the removal of the battery from the pack, the holding member 320 continues to press against the pack under the action of the elastic support component 310, thus holding the pack within the casing and preventing the pack from being lifted along with the battery.

[0036] Specifically, in this embodiment, the elastic support assembly 310 includes a base 311, a guide rod 312, and an elastic element 313. The guide rod 312 is slidably mounted on the base 311, the pressing member 320 is fixedly connected to one end of the guide rod 312, and the elastic element 313 is disposed between the pressing member 320 and the base 311.

[0037] The guide rod 312 can be mounted on the base 311 via a linear bearing, allowing it to slide along its extension direction. After the clamping member 320 abuts against the packaging material, the guide rod 312 can retract under the reaction force of the packaging material, forcing the elastic member 313 to undergo elastic deformation. In this way, the elastic member 313 can generate a restoring force, while the guide rod 312 can guide the clamping member 320 during its extension and retraction, ensuring the stability of the clamping member 320.

[0038] More specifically, multiple guide rods 312 are provided, and the multiple guide rods 312 are arranged in parallel. All multiple guide rods 312 are connected to the pressing member 320, thus further improving the stability of the pressing member 320 during the extension and retraction process.

[0039] Furthermore, in this embodiment, the elastic element 313 is configured as a spring, which is sleeved on the guide rod 312 and clamped between the base 311 and the holding member 320. Under the constraint of the guide rod 312, the elastic element 313 is more reliably installed and less prone to displacement. Of course, in other embodiments, the elastic element 313 can also be configured as an elastic sheet, elastic rope, or other similar element, as long as it can provide elastic restoring force to the holding member 320.

[0040] Furthermore, in this embodiment, the elastic holding mechanism 300 also includes a lifting assembly 330. The elastic support member is connected to the drive end of the lifting assembly 330, and the lifting assembly 330 can drive the elastic support assembly 310 and the holding member 320 to move up and down relative to the clamping mechanism 200. The lifting assembly 330 may be a cylinder, and the lifting direction of the lifting assembly 330 is consistent with the extension and retraction direction of the holding member 320, which usually refers to the vertical direction.

[0041] During unpacking, if a significant number of batteries remain in the package, the package will not be lifted by the weight of the batteries. In this case, the lifting assembly 330 can drive the elastic support assembly 310 and the pressing member 320 to rise relative to the clamping mechanism 200 until the pressing member 320 does not contact the package during the clamping mechanism 200's gripping of the batteries, meaning the elastic pressing mechanism 300 will not function. However, when only the last row or a few rows of batteries remain in the package, the weight of the batteries is insufficient to hold the package against the casing. In this case, the lifting assembly 330 can drive the elastic support assembly 310 and the pressing member 320 to descend relative to the clamping mechanism 200 until the pressing member 320 contacts the package during the clamping mechanism 200's gripping of the batteries, meaning the elastic pressing mechanism 300 will function.

[0042] It should be noted that in other embodiments, the lifting assembly 330 may be omitted, while the pressure holding mechanism 300 is always in operation.

[0043] Please refer to it again. Figures 1 to 3 In this embodiment, the battery unpacking device 10 also includes a bottom support mechanism 900 mounted on the bracket 100. The bottom support mechanism 900 includes a bracket 910 and a drive assembly 920. The bracket 910 can be moved under the clamping mechanism 2000 or moved out from under the clamping mechanism 2000 under the drive of the drive assembly 920.

[0044] The bracket 910 is generally elongated and can be plate-shaped or rod-shaped, and multiple brackets can be installed. The bracket 910 can translate or rotate relative to the support 100, thereby switching its relative position with the clamping mechanism 200. Before the clamping mechanism 200 grips the battery, the bracket 910 can be moved out from under the clamping mechanism 200 under the drive component 920, thus avoiding interference with the clamping mechanism 200. After the clamping mechanism 200 grips the battery, the bracket 910 moves to below the clamping mechanism 200 under the drive component 920. In this way, the bracket 910 can provide support for the battery gripped by the clamping mechanism 200, effectively preventing the battery from falling.

[0045] The battery unpacking device 10 described above first moves towards the battery pack during unpacking, allowing the holding member 320 to elastically contact the pack before the clamping mechanism 200 contacts the battery. As the battery unpacking device 10 continues to approach the pack, the elastic support component 310 is compressed, providing elastic restoring force to the holding member 320. After the clamping mechanism 200 successfully grasps the battery, the battery unpacking device 10 then moves away from the pack to pull the battery from its slot. During this process, the holding member 320 continues to press against the pack under the action of the elastic support component 310, thus holding the pack within the casing and preventing it from moving with the battery. Therefore, the battery unpacking device 10 effectively prevents the pack from being lifted during unpacking.

[0046] 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.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
