Description

Technical Field

[0001] The utility model relates to the field of lithium battery module storage devices, and particularly to a three-dimensional warehouse device for grouped storage of lithium battery modules. Background Art

[0002] During the production process of lithium batteries, automatic grouped storage of lithium battery modules is required. Currently, the conventional method is to use an automated three-dimensional warehouse to achieve this. The three-dimensional warehouse needs to build multi-layered three-dimensional shelves, and storage bins are arranged in an array on the shelves for placing lithium battery modules. The entire three-dimensional warehouse system consists of parts such as shelves, transmission equipment, storage equipment, control systems, communication systems, and computer management and monitoring systems. Multiple systems cooperate to achieve the warehousing, grouping, and outbound of products. The automated three-dimensional warehouse occupies a large space and is composed of multiple mechanical systems and electrical systems. The internal space of the three-dimensional shelf is generally semi-closed.

[0003] After long-term market research, the inventor found that: currently, the construction of a three-dimensional warehouse requires multiple mechanical systems and electrical systems, with a complex system composition, difficult debugging, and high overall cost. And many production enterprises in the industry have limited scales. When used in a production workshop, due to the limited space of the production line, there is no space for placing a conventional three-dimensional warehouse.

[0004] Therefore, it is necessary to provide a new battery module storage device to solve the above technical problems. Summary of the Utility Model

[0005] The utility model provides a three-dimensional warehouse device for grouped storage of lithium battery modules, which is beneficial to solving the problems that the existing three-dimensional warehouse structure occupies a large floor space, has a high cost, and cannot be adapted to the workshop environment with limited production line space.

[0006] The utility model is implemented as follows:

[0007] A three-dimensional warehouse device for grouped storage of lithium battery modules includes a frame. At least two longitudinally spaced storage units are provided on the frame. Each storage unit includes a horizontally arranged chain conveyor. A number of loading platforms are arranged on the chain conveyor. A placement groove is provided on the loading platform. When the loading platform is located on the top end face of the chain conveyor, the placement groove is used for tooling lithium battery modules. Each chain conveyor of each storage unit is configured with an independent driving mechanism. The independent driving mechanism can drive the chain conveyor to drive the loading platform to move step by step. The chain conveyor located below extends at least one end in the long side direction to the outer area of the upper chain conveyor, forming a stepped structure.

[0008] On the basis of the above technical solution, the frame is composed of vertically arranged columns and horizontally arranged frames, and the storage units are arranged on the frames.

[0009] On the basis of the above technical solution, a position sensor is provided on one side of the stepped structure of the frame body corresponding to each of the storage units, and the detection area of the position sensor corresponds to the first stepped working area on the top end surface of the chain plate line.

[0010] On the basis of the above technical solution, the conveying direction of the chain plate line is defined as the front-back direction, and the horizontal orientation perpendicular to this conveying direction is the left-right direction; the carrier platform includes a bottom plate and a stop block. The bottom plate is a horizontally arranged strip-shaped plate structure. The bottom of the bottom plate and the stop block is connected to the chain plate on the chain plate line. Limiting flanges are provided on the left and right sides of the top of the bottom plate. A number of stop blocks are provided on the front and back sides of the bottom plate. The stop block and the inner side of the limiting flange form the storage groove for accommodating the lithium battery module.

[0011] On the basis of the above technical solution, the longitudinal profile of the stop block is an "L" - shaped structure, and the stop blocks located on the front and back sides of the same bottom plate are symmetrically arranged.

[0012] On the basis of the above technical solution, a chamfer structure is provided at the inner corner of the top of the limiting flange and the stop block.

[0013] On the basis of the above technical solution, a position adjustment structure is provided between the bottom of the stop block and the chain plate.

[0014] On the basis of the above technical solution, the position adjustment structure includes a strip-shaped hole and a bolt structure.

[0015] Compared with the prior art, the present utility model has at least the following advantages:

[0016] The present utility model arranges a plurality of storage units distributed at longitudinal intervals. The storage units are composed of a chain plate line and a number of carrier platforms, and are configured with a separate driving mechanism. Moreover, the plurality of storage units form a stepped structure, which is convenient for adapting to an external transfer device to transfer and place the aluminum battery module on the carrier platforms of each storage unit. By using the stepped drive of the chain plate line for the carrier platform, after carrying the lithium battery module, it can be transferred to the inner area for grouped storage. By using the forward and reverse conveying of the chain plate line, it can flexibly cooperate with the feeding and discharging operations of the lithium battery module. This kind of structure is relatively simple, with low manufacturing cost, and at the same time has good flexibility. Multiple layout schemes of the carrier platform can be configured on the chain plate according to requirements, and the length of the chain plate line can be designed according to the actual workshop environment. Therefore, it is beneficial to solve the problems that the existing three-dimensional warehouse structure occupies a large space and has a high cost, and cannot be adapted to the workshop environment with limited production line space.

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are only for the purpose of illustration and do not represent the only implementation.

[0026] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See Figures 1 to 4 , this embodiment discloses a three-dimensional library device for grouped storage of lithium battery modules, which is used for grouped storage of lithium battery modules. The lithium battery modules below are described with product a.

[0028] The three-dimensional library device specifically includes a rack that plays a bearing and supporting role. The rack is composed of a vertical column 1 with a profile structure and a horizontal frame 2.

[0029] In this embodiment, the frame 2 of the rack is divided into three layers, and a total of 3 longitudinally spaced storage units are provided on the frame 2. The storage unit includes a horizontally arranged chain conveyor line 3, and a number of equally spaced loading platforms 4 are arranged on the chain of the chain conveyor line 3 for placing and storing product a.

[0030] Furthermore, in order to enable each storage unit to perform independent feeding operations, the chain conveyor line 3 of each storage unit is configured with an independent drive mechanism. The independent drive mechanism can drive the chain conveyor line 3 in two directions to drive the loading platform 4 to move step by step. The independent drive mechanism in this embodiment is a reduction motor and its supporting transmission structure, which is prior art. Its specific structure and working principle will not be elaborated here. Those skilled in the art can select and implement from the prior art according to the actual operation situation.

[0031] In order to facilitate the adaptation of an external transfer device (such as a manipulator, etc.) to carry product a, at least one end of the chain conveyor line 3 located below extends to the outer area of the upper chain conveyor line 3 in the long side direction, forming a stepped structure, as Figure 1 shown in or 2. In this embodiment, the storage units are aligned on one side and form a stepped structure on the other side, and the exposed part is used as the loading and unloading area for product a.

[0032] Define the conveying direction of the chain conveyor line 3 as the front-back direction, and the horizontal orientation perpendicular to this conveying direction as the left-right direction.

[0033] The loading platform 4 is provided with a placement groove, and the placement groove is used for the tooling lithium battery module when the loading platform 4 is located on the top end face of the chain conveyor line 3.

[0034] Specifically, in combination withFigure 3 and Figure 4 As shown in Figure 4 , the stage 4 includes a bottom plate 41 and stoppers 42. The bottom plate 41 is a horizontally arranged strip-shaped plate structure. The bottoms of the bottom plate 41 and the stoppers 42 are connected to the chain plates on the chain plate line 3. Limiting flanges 411 are provided on the left and right sides of the top of the bottom plate 41. A number of stoppers 42 are provided on the front and rear sides of the bottom plate 41. The stoppers 42 and the inner sides of the limiting flanges 411 form the placement groove for accommodating the lithium battery module.

[0035] Further, the longitudinal profile of the stopper 42 is an "L" - shaped structure. The stoppers 42 on the front and rear sides of the same bottom plate 41 are symmetrically arranged. During use, the product a located in the placement groove is limited front and back to prevent the product a from falling off.

[0036] In order to reduce the damage to the product a caused by rigid scratching between the product a and the stage during loading and unloading, chamfer structures are provided at the inner corners of the tops of the limiting flanges 411 and the stoppers 42.

[0037] Further, a position sensor 6 is provided on one side of the stepped structure of the frame 2 corresponding to each storage unit. In this embodiment, the position sensor 6 is an optoelectronic sensor. The detection area of the position sensor 6 corresponds to the first stepped working area on the top end surface of the chain plate line 3, and is used to detect whether the stage at this position has moved in place. This is beneficial to ensuring the accuracy of the stepped movement of the stage, so as to cooperate with the external transfer device to perform loading and unloading operations more accurately and reliably.

[0038] Further, as Figure 1 shown, a cover plate 5 is provided on the top of the uppermost storage unit to protect the product a in the storage state, while the lower storage units use the frame 2 of its adjacent upper storage unit as a covering structure, making full use of the structural space.

[0039] In the specific implementation process, they are placed in groups by category. In this embodiment, they can be divided into three groups. Taking the uppermost storage unit as an example for elaboration, the product a is transported by an external transfer device to the placement groove at the first working position of this storage unit. Subsequently, the independent drive mechanism rotates forward, causing the chain plate line 3 to move the product a backward for storage. At the same time, the stage at the next working position rotates to the first working position to wait for receiving materials. The stepped operation can prevent a number of products a one by one to form group storage. When taking materials, the independent drive mechanism rotates in reverse to send the products a back to the first working position one by one, and is removed by the external transfer device.

[0040] In other embodiments, in order to improve the device performance and meet the storage requirements of lithium battery modules of various specifications, a position adjustment structure is provided between the bottom of the stopper 42 and the chain plate. Among them, the position adjustment structure includes a strip-shaped hole and a bolt structure. The strip-shaped hole can be arranged horizontally or front-back. This is prior art, and its specific structure and working principle will not be elaborated here. Those skilled in the art can select and implement from the prior art according to the actual operation situation.

[0041] In other embodiments, a spring that can be telescoped back and forth and a corresponding guiding and limiting structure can also be configured between the stopper 42 and the chain plate, so that the stopper 42 can elastically clamp the product a.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
