Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a blade battery module stacking device. Background Technology

[0002] With the large-scale application of blade batteries, more and more car models are starting to use them. Before the blade batteries are assembled into battery packs, they need to be stacked into modules and then installed into the battery packs. Due to the rapid iteration of blade batteries and the need for rapid production ramp-up, some production lines have gradually shifted from automatic module stacking to manual module stacking to achieve rapid production ramp-up to meet market capacity demands. Due to the characteristics of blade batteries and the uncontrollable factors of personnel, the existing manual module stacking tooling cannot meet the usage requirements.

[0003] The existing manual stacking module tooling uses a comb mechanism to position the battery terminals, and then the processed blade batteries are manually placed into the positioning slots to assemble the battery modules. Since the explosion-proof valve and the terminals of the blade batteries are on the same side, there are many uncontrollable factors during the manual placement process. The positioning comb may hit the explosion-proof valve, causing damage to the valve and battery leakage, which will lead to product scrap and failure to meet product quality requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to prevent damage to the explosion-proof valve.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A blade battery module stacking device includes a stacking base and a guide positioning mechanism. The guide positioning mechanism is fixed on both sides of the stacking base that are parallel to the stacking direction.

[0007] The guiding and positioning mechanism includes a comb frame, a rotating shaft, a rotating block, and an elastic element. One end of the comb frame is fixed to the inner side wall of the stacking base, and the other end has multiple comb grooves along its length. A rotating shaft is provided on the comb frame along its length, and a rotating block corresponding to the number of comb grooves is provided on the rotating shaft. One end of the rotating block is connected to the comb frame through the elastic element, and the other end is located above the comb grooves.

[0008] During the placement of the blade battery, the explosion-proof valve surface at its end contacts the end face of the rotating block away from the elastic element. The two are in surface-to-surface contact, which prevents the stacking device from damaging the explosion-proof valve at the end of the blade battery, thus preventing damage to the explosion-proof valve, improving the pass rate when manually stacking modules, and reducing the scrap rate of products.

[0009] Preferably, the comb frame is provided with a first pull rod along its length, and the end of each elastic element away from the rotating block is connected to the first pull rod.

[0010] Preferably, both ends of the first pull rod are fixed to the ends of the comb frame by fixing blocks.

[0011] Preferably, the fixing block has a waist-shaped hole, and the fixing block is fixed to the end of the comb frame by a fixing bolt passing through the waist-shaped hole.

[0012] The height of the fixing block on the comb frame is adjusted by changing the position of the fixing bolt on the waist-shaped hole, thereby adjusting the height of the first pull rod on the comb frame, and then adjusting the extension length of the elastic element, so as to adjust the elastic force of the elastic element to meet the rotation of the rotating block.

[0013] Preferably, a second pull rod is provided at the end of the rotating block away from the comb tooth groove, and one end of the elastic element is connected to the second pull rod.

[0014] Preferably, a U-shaped groove is provided at the end of the rotating block away from the comb tooth groove, and the second pull rod is fixed in the U-shaped groove.

[0015] Preferably, the elastic element is a return spring.

[0016] Preferably, the end of the rotating block near the comb groove is chamfered.

[0017] The chamfering on the rotating block prevents the sharp ends of the rotating block from scratching the blade battery.

[0018] Preferably, the stacking base includes a base plate and side plates, with two sets of parallel side plates provided on the base plate, and the comb frame fixed to the inner wall of the side plates.

[0019] Preferably, the base plate is further provided with multiple sets of support plates along the battery stacking direction.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. During the process of placing the blade battery, the explosion-proof valve surface at its end contacts the end face of the rotating block away from the elastic element. The two are in surface-to-surface contact, which prevents the stacking device from damaging the explosion-proof valve at the end of the blade battery, thus preventing damage to the explosion-proof valve, improving the pass rate when manually stacking modules, and reducing the scrap rate of products.

[0022] 2. By changing the position of the fixing bolt on the waist-shaped hole, the height of the fixing block on the comb frame is adjusted, thereby adjusting the height of the first pull rod on the comb frame, and then adjusting the extension length of the elastic element, so as to adjust the elastic force of the elastic element to meet the rotation of the rotating block.

[0023] 3. The chamfering on the rotating block prevents the sharp ends of the rotating block from scratching the blade battery. Attached Figure Description

[0030] To facilitate understanding of the technical solution of this utility model by those skilled in the art, the technical solution of this utility model will now be further described in conjunction with the accompanying drawings.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically limited.

[0033] See Figure 1This embodiment discloses a blade battery module stacking device, including a stacking base 1 and a guide positioning mechanism 2. Multiple sets of guide positioning mechanisms 2 are fixed on both sides of the stacking base 1 parallel to the stacking direction. In this embodiment, two sets of guide positioning mechanisms 2 are fixed on one side of the stacking base 1 parallel to the stacking direction, but not limited to two sets. The specific number depends on the actual battery stacking requirements.

[0034] The stacking base 1 includes a base plate 11, side plates 12 and support plates 13. Two sets of parallel side plates 12 are provided on the base plate 1. Two sets of guide positioning mechanisms 2 are fixed on the inner wall of each set of side plates 12. Two sets of parallel support plates 13 are fixed on the base plate 11 between the two sets of side plates 12 along the battery stacking direction to support the blade battery 3.

[0035] See Figures 2 to 5 The guide positioning mechanism 2 includes a comb frame 21, a rotating shaft 22, a rotating block 23, an elastic element 24, a first pull rod 25, a second pull rod 26, and a fixing block 27. One end of the comb frame 21 is fixed to the inner wall of the side plate 12, and the other end is provided with multiple comb grooves 211 along its length direction. The end of the comb frame 21 is flush with the bottom of the comb groove 211 in the vertical direction. A set of blade batteries 3 are snapped into one comb groove 211.

[0036] A rotating shaft 22 and a first pull rod 25 are arranged along the length of the comb frame 21. A rotating block 23 corresponding to the number of comb grooves 211 is arranged on the rotating shaft 22. The rotating block 23 can rotate around the rotating shaft 22 as the rotation center. In this embodiment, the first pull rod 25 is arranged below the rotating block 23. A U-shaped groove 231 is opened at one end of the rotating block 23. A second pull rod 26 is fixed in the U-shaped groove 231. One end of the elastic element 24 is connected to the first pull rod 25 and the other end is connected to the second pull rod 26. In this embodiment, the elastic element 24 is a return spring.

[0037] The end of the rotating block 23 away from the elastic element 24 is positioned above the comb groove 211, so that a gap is formed between the rotating block 23 and the bottom wall of the comb groove 211 to engage the upper electrode of the blade battery 3, and also to reserve rotation space when the rotating block 23 rotates downward.

[0038] The rotating block 23 has a chamfer at the end near the comb groove 211 to prevent its sharp end from scratching the blade battery 3; similarly, a chamfer is also provided on the bottom wall of the comb groove 211 near the end of the rotating block 23.

[0039] The first pull rod 25 is fixed to the ends of the comb frame 21 by fixing blocks 27 at both ends. Specifically, the fixing block 27 has a waist-shaped hole 271 in its vertical direction. The fixing block 27 is fixed to the end of the comb frame 21 by fixing bolts passing through the waist-shaped hole 271. The height of the fixing block 27 on the comb frame 21 is adjusted by changing the position of the fixing bolts on the waist-shaped hole 271, thereby adjusting the height of the first pull rod 25 on the comb frame 21, and thus adjusting the extension length of the elastic element 24, so as to adjust the elastic force of the elastic element 24 to meet the rotation of the rotating block 23.

[0040] The working principle of this utility model is as follows: The blade battery 3 is manually placed from above the stacking fixture between two sets of opposing guide positioning mechanisms 2. During the downward placement of the blade battery 3, when the terminal post on the blade battery 3 contacts the rotating block 23, the rotating block 23 rotates on the rotating shaft 22 toward the comb groove 211 under the downward pressure of the blade battery 3. When the terminal post on the blade battery 3 is engaged in the gap formed between the rotating block 23 and the bottom wall of the comb groove 211, the rotating block 23 rotates upward to reset under the elastic action of the elastic member 24, returning to the initial position, thus completing the stacking and installation of the blade battery 3.

[0041] In summary, during the lowering process of the blade battery 3 in this embodiment, the explosion-proof valve surface at its end contacts the end face of the rotating block 23 away from the elastic element 24. The two are in surface-to-surface contact, which prevents the stacking device from damaging the explosion-proof valve at the end of the blade battery 3, thus preventing damage to the explosion-proof valve, improving the pass rate when manually stacking modules, and reducing the scrap rate of products.
