Description

Technical Field

[0001] The present invention belongs to the technical field of equipment for lithium battery assembly, and particularly relates to an assembly and repair equipment for the cascade utilization of lithium batteries. Background Art

[0002] Cascade utilization means that the performance of a product has decayed to the point where it can no longer be used in its original field, but it can be used at a lower level. In a field with relatively lower performance requirements, it can be used for a period of time to achieve the purpose of energy conservation and environmental protection. The most common example of this method is that after military equipment is phased out, it can be transferred to the civilian field, and even further transferred, and finally can be used for teaching or exhibition.

[0003] For the cascade utilization of lithium batteries, generally, after the power lithium battery has decayed by 20%, with a little disassembly, repair, and assembly, or even without going through the above steps, it can then be used in the energy storage field for household electricity, such as the energy storage battery for agricultural tools.

[0004] Therefore, in the above disassembly, repair, and assembly steps, a stable and convenient operation platform is required, which is one of the assembly and repair equipment for the cascade utilization of lithium batteries, to ensure that: the battery cell strings or single battery cells are convenient to pick up, the scrap and garbage during the assembly and repair process can be removed in time, the failed battery cell strings or single battery cells can be temporarily stored, and the assembled lithium batteries can be quickly transported out.

[0005] The Chinese utility model patent with the patent publication number CN215148821U and the publication date of December 14, 2021, discloses a lithium battery auxiliary assembly device, the structure of which includes an adjustment mechanism and a collection mechanism. By setting a threaded rod, a forward and reverse motor, a threaded barrel, and a support rod, the operating platform can be adjusted in height according to the needs of the user. Moreover, by setting a guide plate, a placement plate, and a collection box, the waste generated during the assembly on the operating platform can be quickly collected and processed.

[0006] However, in the actual use process of the auxiliary assembly device in this utility model patent, there are at least the following two deficiencies. In other words, these are the technical problems to be solved by the present invention.

[0007] First, it is difficult to cooperate with a conveyor belt or an assembly line, so the overall efficiency is relatively low.

[0008] Second, there is no reasonable temporary storage position for the failed or faulty single battery cells or battery cell strings found during assembly, and they can only be placed on the operating platform together with the finished lithium batteries, which is very troublesome.

[0009] Therefore, in summary, there is an urgent need for a new operating platform that can quickly discharge waste, be quickly assembled, and can reasonably store failed or faulty battery cell monomers or battery cell strings, as part of the assembly and repair equipment, and ultimately be used in the field of lithium battery secondary utilization. Summary of the Invention

Specific embodiments

[0032] The following is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.

[0033] As shown in the attached Figure 1-7 As shown, a battery assembly and repair device for lithium battery cascade utilization, the structure includes a lower plate unit 1 for temporarily storing the faulty battery cell string a, an inclined plate unit 2 provided on the lower plate unit 1 and used for sliding the faulty battery cell string a and waste scraps b, an upper plate unit 3 provided on the inclined plate unit 2 and used for assembling the finished lithium battery c, and a supporting vertical pipe unit 4 inserted on the lower plate unit 1, supported on the battery cell string conveyor rack d and the finished product conveyor rack e, and used for discharging the waste scraps b downward.

[0034] In the prior art, the assembly steps from the battery cell string k to the finished lithium battery c successively include: separation and fixation of the battery cell string, nickel strip series connection, battery bundling, and soldering.

[0035] Therefore, in this embodiment, the faulty battery cell string a may be a situation where the battery cells are not sufficiently fixed or connected to each other, and the number of battery cells is not equal, and the waste scraps b include sundries such as wire ropes and tapes.

[0036] In addition, the lower plate unit 1, the inclined plate unit 2, the upper plate unit 3, and the supporting vertical pipe unit 4 together form the operation platform of the assembly and repair device. The operation platform is directly erected and supported on the battery cell string conveyor rack d and the finished product conveyor rack e, ensuring that the entire lithium battery cascade utilization assembly and repair operation is more convenient and efficient.

[0037] Finally, the general usage method of this operation platform is as follows.

[0038] 1. The battery cell string k moves towards the operation platform on the battery cell string conveyor rack d. An operator, or even an operating robotic arm, slides the battery cell string k upwards onto the high-position plate unit 3 to start the assembly and repair.

[0039] 2. The waste edge materials b generated during this period, and the possible faulty battery cell strings a, all slide down on the inclined plate unit 2. The former falls concentratedly at the low-position plate unit 1, and the latter stops on the low-position plate unit 1 for temporary storage.

[0040] 3. Finally, the finished lithium battery c slides down on the other side of the high-position plate unit 3, lands on the finished product conveyor rack e and is removed, and a single complete lithium battery assembly and repair operation is all over.

[0041] The low-position plate unit 1 includes a low-position horizontal plate 101, an opening 102 provided on the low-position horizontal plate 101 and used for inserting the support vertical pipe unit 4, two inner inclined plates 103 provided on the upper surface of the low-position horizontal plate 101 and used for guiding the waste edge materials b into the support vertical pipe unit 4, and two outer L-shaped plates 104 provided on the upper surface of the low-position horizontal plate 101 and used for blocking the faulty battery cell strings a.

[0042] In this embodiment, the inner inclined plates 103 and the outer L-shaped plates 104 can be optionally fixedly connected to the support vertical pipe unit 4, or fixedly connected to the low-position horizontal plate 101, or fixedly connected to both places.

[0043] The inclined plate unit 2 includes an inclined plate 201 provided on the side edge of the low-position horizontal plate 101, two end baffles 202 respectively provided at both ends of the inclined plate 201 and connecting the outer L-shaped plates 104, and two partition plates 203 provided on the upper surface of the inclined plate 201 and respectively used for connecting the two inner inclined plates 103.

[0044] In this embodiment, the function of the inclined plate 201 is to completely distinguish the "operation area" and the "non-operation area", that is, the corresponding high-position plate unit 3 and low-position plate unit 1. The end baffles 202 are used to prevent the faulty battery cell strings a from sliding out and falling to the ground, and the partition plates 203 ensure that the waste edge materials b enter between the two inner inclined plates 103, and at the same time allow the faulty battery cell strings a to enter between the inner inclined plates 103 and the outer L-shaped plates 104.

[0045] In other words, the low-position horizontal plate 101 is divided into a temporary storage area for the faulty battery cell strings a on the left, a falling area for the waste edge materials b in the middle, and a temporary storage area for the faulty battery cell strings a on the right.

[0046] The high-position plate unit 3 includes a high-position horizontal plate 301 disposed on the side of the inclined plate 201, and two landslide plates 302 respectively disposed at both ends of the high-position horizontal plate 301 and supported on the battery cell string conveyor rack d and the finished product conveyor rack e.

[0047] In this embodiment, when an operator or a robotic arm slides on the landslide plate 302 to lift the battery cell string k, it is relatively labor-saving, and when sliding down the finished lithium battery c on the landslide plate 302, the landing point is relatively accurate, and the finished lithium battery c is not likely to fall outside the finished product conveyor rack e.

[0048] The high-position plate unit 3 further includes an L-shaped groove 303 disposed on the lower surface of the landslide plate 302 and used for clamping the battery cell string conveyor rack d or the finished product conveyor rack e.

[0049] In this embodiment, the two L-shaped grooves 303 respectively correspond to the battery cell string conveyor rack d and the finished product conveyor rack e, ensuring that the operating platform is not likely to fall or slide left and right.

[0050] The support vertical pipe unit 4 includes a circular vertical pipe 401 disposed on the opening 102 and used for sleeving the tubular blue shell paper f, a waste corner material opening 402 disposed on the circular vertical pipe 401 and located between the two inner inclined plates 103, and two radial plates 403 disposed on the circular vertical pipe 401, supported on the battery cell string conveyor rack d and the finished product conveyor rack e, and used for supporting the low-position horizontal plate 101.

[0051] In the prior art, blue shell paper is used and placed between adjacent battery cell strings k to prevent the outer skin of the battery cell string k from being damaged and thus short-circuited. Therefore, the circular vertical pipe 401 for the waste corner material b to fall is used as the installation and rotatable central axis of the tubular blue shell paper f.

[0052] In addition, in this embodiment, one end of the radial plate 403 is fixedly connected to the circular vertical pipe 401, and the other end is placed on the battery cell string conveyor rack d or the finished product conveyor rack e. The radial plate 403 and the landslide plate 302 are the main supporting positions of the operating platform.

[0053] The vertical height of the outer L-shaped plate 104 is higher than that of the inner inclined plate 103 to support the tubular blue shell paper f.

[0054] In this embodiment, the vertical width of the outer L-shaped plate 104 is 30 - 50 cm, ensuring: 1. The faulty battery cell string a is not likely to cross and land there; 2. When the tubular blue shell paper f is in normal use, its lower end will not be impacted by the faulty battery cell string a. In other words, the height of the battery cell string generally does not reach 30 - 50 cm.

[0055] The support vertical pipe unit 4 further includes a reinforcing plate 404 which is arranged on the circular vertical pipe 401, located below the radial plate 403, and used for supporting on the scrap conveying rack g.

[0056] In this embodiment, the battery cell string conveying rack d and the finished product conveying rack e are parallel to each other, the scrap conveying rack g is perpendicular to both of them, the former two are on the left and right, the latter is in the front lower part of the operation platform, and the reinforcing plate 404 can also assist the landslide plate 302 and the auxiliary radial plate 403 to support the entire operation platform as well.

[0057] The support vertical pipe unit 4 further includes an enlarged opening 405 which is arranged on the lower end face of the circular vertical pipe 401 and used for discharging the waste scrap b.

[0058] In this embodiment, the enlarged opening 405 is located at the relative downstream of the scrap conveying direction h, which can prevent the waste scrap b from being unable to come out of the circular vertical pipe 401, and also prevent it from being scattered and spread greatly on the scrap conveying rack g.

[0059] Frame engaging grooves 406 are provided on the lower surfaces of the radial plate 403 and the reinforcing plate 404.

[0060] In this embodiment, the frame engaging groove 406 on the radial plate 403 corresponds to the battery cell string conveying rack d and the finished product conveying rack e, and the frame engaging groove 406 on the reinforcing plate 404 corresponds to the scrap conveying rack g.

[0061] On the other hand, after having the enlarged opening 405, even if the circular vertical pipe 401 and the reinforcing plate 404 are very close to the conveyor belt of the scrap conveying rack g, it does not affect the falling and conveying effect of the waste scrap b.

[0062] Finally, the advantages of the assembly and repair equipment in this embodiment are summarized as follows.

[0063] First, the low-position plate unit 1, the inclined plate unit 2, the high-position plate unit 3, and the support vertical pipe unit 4 together form the operation platform of the assembly and repair equipment, and this platform is directly erected on the battery cell string conveying rack d, the finished product conveying rack e, and the scrap conveying rack g, ensuring that the entire assembly and repair operation of the lithium battery secondary utilization is more convenient, fast, and efficient.

[0064] Second, the low-position plate unit 1 has both a temporary storage area for the faulty battery cell strings a and a discharge area for the waste scrap b, and its height is lower than that of the high-position plate unit 3. Therefore, when assembling the lithium battery finished products c with the effective battery cell strings, it is more orderly and convenient.

[0065] Thirdly, the supporting vertical pipe unit 4 is not only the discharge position of the waste corner materials b, but also the supporting and installation position of the operation platform, and also the installation part of the tubular kraft paper f, making the structure of the entire operation platform more compact and stable.

[0066] Fourthly, the sliding plate 302 can not only facilitate the lifting of the battery cell string k, but also enable the finished lithium battery c to fall precisely, and is also another supporting position of the entire operation platform, making the installation and use of the operation platform very stable and efficient.

[0067] Fifthly, the supporting vertical pipe unit 4 has stable support, and it is very convenient for the waste corner materials b to enter and discharge on the supporting vertical pipe unit 4.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various modifications can be made without departing from the purpose of the present invention.
