Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a stacking device for processing lithium iron phosphate batteries. Background Technique

[0002] With the rapid development of electronic technology, at present, lithium iron phosphate battery pack products have been widely used in production and life. As an energy storage battery pack product, when in use, it needs to be connected to peripheral unit devices such as a photovoltaic unit or other electric energy conversion units, a control host, and an inverter to achieve charge and discharge operations. Lithium iron phosphate battery pack products are usually individual battery packs, usually in the form of block-shaped battery packs, with limited battery capacity and difficult to meet the growing energy consumption requirements. Therefore, multiple lithium iron phosphate battery packs can be stacked to form a whole and then connected in parallel, which can increase the total capacity and discharge capacity of the lithium iron phosphate battery pack.

[0003] When connecting lithium iron phosphate battery packs in parallel, the following points need to be noted: The same voltage: Ensure that the voltages of the lithium iron phosphate battery packs connected in parallel are the same to avoid problems such as uneven current flow and damage to the battery packs. The same capacity: Ensure that the capacities of the lithium iron phosphate battery packs connected in parallel are the same to avoid problems such as charge and discharge imbalance and affecting the overall performance. Connection method: Adopt a suitable parallel connection method. Generally, the positive poles are connected to each other, and the negative poles are connected to each other, and then connected through wires or connectors. Pay attention to the quality of the connection line and good contact to reduce the connection resistance and ensure the parallel connection effect. Charge and discharge management: For the battery packs connected in parallel, a suitable charge and discharge management system needs to be adopted to ensure that the charge and discharge processes of the battery packs are effectively monitored and controlled to avoid situations such as overcharging and over-discharging.

[0004] In the prior art, a crane or a fixture is used to stack multiple groups of lithium iron phosphate battery packs in sequence. During the stacking process, the exteriors of multiple groups of lithium iron phosphate batteries are bonded and fitted together through an adhesive. In actual operation, after applying the adhesive to the exterior of the battery pack, another group of battery packs is placed on the coating layer, and then a pressing component is used to press and fit. The pressing effect is mainly achieved by a hydraulic rod or an electric telescopic rod. However, when pressing, the coating layer on the exterior of the lithium iron phosphate battery pack is prone to sliding when contacting the exterior of another group of battery packs, resulting in the positions of the two groups of battery packs not being quickly aligned and fitted, reducing production efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the prior art that the coating layer on the exterior of the lithium iron phosphate battery pack is prone to sliding when contacting the exterior of another group of battery packs, resulting in the positions of the two groups of battery packs not being quickly aligned and fitted, reducing production efficiency, and a stacking device for processing lithium iron phosphate batteries is proposed.

[0026] Embodiment:

[0027] Referring to Figures 1 - 5 , a stacking device for processing lithium iron phosphate batteries, includes a support base 1, on which a limiting cage is fixedly connected, and the limiting cage is used for placing battery packs, and its components are described as follows: On the support base 1, two groups of symmetric L-shaped plates 2 are also fixedly connected, and the distance between the L-shaped plates 2 matches the shape of the lithium iron phosphate battery pack. The lithium iron phosphate battery pack can be placed between the L-shaped plates 2, and then stacked or processed and placed. At the end of the L-shaped plate 2, an extension plate 201 is fixedly connected, and the extension plate 201 is perpendicular to the L-shaped plate 2. The two sides of the lithium iron phosphate battery pack can be limited by the extension plate 201, thereby forming the shape of the limiting cage to limit the outside of the battery pack.

[0028] Moreover, a groove is opened at the inner bottom of the support base 1, and a roller 101 is rotatably connected in the groove. The rollers 101 are equidistantly distributed in multiple groups and are used for sliding the lithium iron phosphate battery pack. A fixture or a crane can be used to place the lithium iron phosphate battery pack on the rollers 101, and then the rollers 101 can be used to move the lithium iron phosphate battery pack so that the side wall of the lithium iron phosphate battery pack abuts against the L-shaped plate 2, thereby pre-limiting the lithium iron phosphate battery pack.

[0029] On the support base 1, a mounting seat 3 is also fixedly connected, and a connecting plate 4 is slidably connected to the mounting seat 3. At the bottom of the connecting plate 4, a connecting shaft 402 is fixedly connected, and a limiting disk is fixedly connected to the bottom of the connecting shaft 402. The cross-section of the limiting disk is circular and can rotate or slide in a chute 301. A chute 301 is opened on the mounting seat 3, and the connecting shaft 402 is arranged in the chute 301 and is used for rotating or sliding the position of the connecting plate 4. There are two groups of mounting seats 3, and the two groups of mounting seats 3 are symmetrically arranged on one side of the support base 1.

[0030] On both sides of the extension plate 201, there are also slidingly connected tension rods 601, and a main connection ring 602 is provided at the end of the tension rod 601. Moreover, on both sides of the connecting plate 4, there are respectively rotatably connected movable rods 5, and an auxiliary connection ring 501 is fixedly connected to the end of the movable rod 5. Furthermore, the main connection ring 602 and the auxiliary connection ring 501 are connected by a limit post, and the limit post can lock the main connection ring 602 and the auxiliary connection ring 501 to each other, so that they can be detachably connected and used together.

[0031] On both sides of the extension plate 201, there are also fixedly connected electric telescopic rods 6, and the tension rod 601 is fixedly connected to the output end of the electric telescopic rod 6. By means of the electric telescopic rod 6, the position of the tension rod 601 can be pulled, so that its main connection ring 602 can drive the auxiliary connection ring 501 to move, and at the same time, the position of the connecting plate 4 can be moved. A limit plate 401 is also fixedly connected to the connecting plate 4.

[0032] First of all, when it is necessary to place the lithium iron phosphate battery pack into the limit cage, the tension rod 601 and the connecting plate 4 are in a separated state. Then, the connecting plate 4 is rotated to one side of the opening end of the limit cage. At this time, the contact surface of the limit plate 401 does not abut against the outside of the battery pack. Subsequently, the lithium iron phosphate battery pack is placed on the rotating roller 101 and moved. Then, the lithium iron phosphate battery pack is moved to the vertical included angle between the L-shaped plate 2 and the extension plate 201. At this time, an adhesive can be applied to the outside of the lithium iron phosphate battery pack. Then, another group of lithium iron phosphate battery packs are placed into the limit cage for stacking.

[0033] When it is necessary to quickly align the stacked lithium iron phosphate battery packs, the main connection ring 602 and the auxiliary connection ring 501 on the electric telescopic rod 6 are connected by a limit post. At this time, the limit post can lock the main connection ring 602 and the auxiliary connection ring 501 to each other. Subsequently, the electric telescopic rod 6 drives the tension rod 601 to move back. The contact surface of the limit plate 401 can abut against the outside of the battery pack, so that the limit plate 401 can push the outside of the lithium iron phosphate battery pack and apply pressure to it, so as to move the lithium iron phosphate battery pack to the vertical included angle between the L-shaped plate 2 and the extension plate 201 for quick limiting.

[0034] When an adhesive is applied to the outside of a group of lithium iron phosphate battery packs, the adhesive is mainly epoxy resin glue, and the curing time of the epoxy resin glue is usually 6 hours to 24 hours. The adhesive forms a coating layer. Then, another group of lithium iron phosphate battery packs are placed on the coating layer, and then another layer of adhesive is brushed to stack the lithium iron phosphate battery packs. During this process, the two symmetrical extension plates 201 will continuously limit the position of the lithium iron phosphate battery packs. At the same time, when the stacking layer number is appropriate, the main connection ring 602 and the auxiliary connection ring 501 are connected by a limit post.

[0035] Subsequently, the switch of the electric telescopic rod 6 is turned on. At this time, the end of the lithium iron phosphate battery pack will quickly abut against the L-shaped plate 2, thereby preventing the lithium iron phosphate battery pack from sliding during stacking. It can also quickly align and fit the stacked lithium iron phosphate battery packs, improving production efficiency. Subsequently, the top lithium iron phosphate battery is pressed down by the pressing component to compact the lithium iron phosphate battery packs, ensuring no gaps between the battery packs. Subsequently, the compacted battery packs can also be moved by the rotating roller 101.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
