Description

Technical Field

[0001] The present invention relates to the field of battery assembly, and in particular to a blade battery packing method, a battery module packing system and a readable storage medium. Background Art

[0002] With the development of blade battery technology, more and more battery modules are using blade batteries, and blade batteries are being used in more and more scenarios. Blade batteries are thin and long, shaped like blades. Blade batteries include battery cells, with poles on both sides of the battery cells. Battery modules include multiple battery cells, and the poles of the battery cells are electrically connected using connecting sheets.

[0003] The inventors have found that there are at least the following problems in the prior art: Since the blade battery poles are located on both sides of the battery cell, their position is relatively special. In the process of assembling the battery module, it is necessary to consider whether other components will affect the normal welding of the connecting piece. When the number of blade batteries included in the battery module is different or the height of the battery tray exceeds the height of the blade battery poles, the connecting piece cannot be welded after the battery module is placed in the box. Also, because the poles are located on both sides of the battery cell, it is difficult for the blade battery to be placed in the box by adding sufficient constraints on the side of the battery module like the square shell battery.

Figure 2 A schematic diagram of a first end of a blade battery provided in an embodiment of the present invention. Figure 3 A schematic diagram of the second end of the blade battery provided in an embodiment of the present invention. Figure 4 A schematic diagram of multiple blade batteries arranged side by side according to an embodiment of the present invention.

[0099] See also Figures 1 to 3 The blade battery 6 includes a shell, end caps at both ends of the shell, and a positive pole 61 and a negative pole 62 arranged on the end caps. A positive pole 61 and a negative pole 62 are arranged on each end cap, and an injection hole is arranged on one of the end caps to inject electrolyte into the shell. In order to block the injection hole, the blade battery 6 includes a sealing plate 63, which is detachably arranged at the injection hole to block the injection hole. The sealing plate 63 protrudes from the end cap. Hereinafter, the end of the blade battery 6 provided with the injection hole is referred to as the first end, and the end of the blade battery 6 not provided with the injection hole is referred to as the second end. The positive pole 61, the negative pole 62 and the sealing plate 63 of the first end of the blade battery 6 all protrude from the end cap. The positive pole 61 and the negative pole 62 of the second end of the blade battery 6 protrude from the end cap. The first end of the blade battery 6 has more parts protruding from the end cap, and the second end of the blade battery 6 has fewer parts protruding from the end cap.

[0100] See also Figure 4 The arrangement of the plurality of blade batteries 6 is such that the end of the first blade battery 6 provided with the injection hole is adjacent to the end of the second blade battery 6 not provided with the injection hole, and the end of the second blade battery 6 not provided with the injection hole is adjacent to the end of the third blade battery 6 provided with the injection hole. The plurality of blade batteries 6 are arranged side by side in sequence. Figure 4 Taking 8 blade batteries 6 as an example, the left side is the end of the first blade battery 6A provided with a liquid injection hole, and the rightmost side is the end of the eighth blade battery 6A not provided with a liquid injection hole.

[0102] See also Figure 5 The embodiment of the present invention provides a blade battery packaging method, comprising the following steps:

[0103] Step S100 , arranging a plurality of blade batteries 6 side by side on the base plate tooling 1 .

[0104] In some embodiments, in order to improve the electrical performance of the blade battery 6, the following steps may be included before step S100: cleaning the poles of each blade battery 6. Both the positive pole 61 and the negative pole 62 of the blade battery 6 need to be cleaned, so that the subsequent electrical connection between the connecting piece 10 and the positive pole 61 and the negative pole 62 is more reliable and has better conductivity.

[0105] See also Figure 6 , the bottom plate fixture 1 plays a role in supporting and limiting the blade battery 6. The bottom plate fixture 1 includes a bottom plate 11, at least two support beams 12 and limiters 13 arranged in pairs. The bottom plate 11 is constructed as a flat plate. The bottom plate 11 is located at the bottom of the bottom plate fixture 1, and the bottom plate 11 is used to support and fix the support beams 12 and the limiters 13. Each support beam 12 is arranged in parallel and at intervals on the top of the bottom plate 11, and each support beam 12 is fixedly connected to the bottom plate 11. The length of each support beam 12 is slightly shorter than the length of the bottom. One of the support beams 12 is located at one edge of the bottom plate 11 in the width direction, and the other support beam 12 is located at the other edge of the bottom plate 11 in the width direction. Each blade battery 6 is placed on the top of the two support beams 12 and is supported by the two support beams 12. One of the limiters 13 is located at one end of each support beam 12, and the other limiter 13 is located at the other end of each support beam 12. The limiter 13 is fixedly connected to the support beam 12, which can be specifically fixed by welding, bolting, riveting, etc. All blade batteries 6 are arranged side by side between two limiters 13. Two limiters 13 clamp all blade batteries 6. The distance between the two limiters 13 is determined by the number of blade batteries 6 to form a module. Each limiter 13 can be a plate, a beam or a bump. The base plate tooling 1 of the above structure has strong versatility and low production cost.

[0106] In some embodiments, the fixed connection position of the limit member 13 and the support beam 12 is adjustable. There are many specific implementation methods. One method is to provide a plurality of fixing holes distributed along the length direction of the support beam 12 on the support beam 12. By fixedly connecting the limit member 13 to different fixing holes, the fixed position of the limit member 13 on the support beam 12 is changed, and then the distance between the two limit members 13 is changed, so that the base plate tooling 1 can be suitable for battery modules of different models. Here, the battery module includes a plurality of blade batteries 6, and the distance between the limit members 13 is determined according to the number of blade batteries 6. The more blade batteries 6 the battery module includes, the greater the distance between the two limit members 13.

[0107] Another way to adjust the fixed connection position of the limit member 13 and the support beam 12 is: a mounting groove distributed along the length direction of the support beam 12 is set at the top of the support beam 12, and the fixed position of the limit member 13 and the support beam 12 is changed by fixing the limit member 13 at different positions of the mounting groove, thereby changing the distance between the two limit members 13 to adapt to different types of battery modules.

[0108] In some embodiments, the installation positions of each stopper 13 and the support beam 12 are adjustable. In other embodiments, the installation positions of one stopper 13 and the support beam 12 are adjustable. The largest side surfaces of the blade batteries 6 fit together, and the largest side surface of the outermost blade battery 6 fits with the stopper 13.

[0109] After step S100, each blade battery 6 is placed on the bottom plate fixture 1, and each blade battery 6 is clamped against the stopper 13, and adjacent blade batteries 6 are not fixed and are independent blade batteries 6. Each blade battery 6 may be uneven in the Y direction (i.e., the length direction of the stopper 13), and the following step S200 can be used to align each blade battery 6 in the Y direction.

[0110] Step S200, using the end plate fixture 2 to clamp the end of each blade battery 6 with a pole. The pole refers to at least one of a positive pole and a negative pole. In this embodiment, the end plate fixture 2 can accommodate all the parts of the end of the blade battery 6 protruding from the end cover, so as to clamp the end of the blade battery 6 without interfering with or damaging the blade battery 6.

[0111] See also Figure 7 The end plate tooling 2 includes end plates arranged in pairs: a first end plate and a second end plate. The first end plate and the second end plate cooperate to clamp the two ends of the blade battery 6. The first end plate and the second end plate are arranged in parallel, and the first end plate and the second end plate are arranged along the X direction. The stopper 13 introduced above is arranged along the Y direction.

[0112] The structures of the first end plate and the second end plate are basically the same, except that the distribution of the first positioning groove 22 and the second groove is opposite: that is, the first positioning groove 22 of the first end plate is opposite to the second positioning groove 23 of the second end plate, and the second positioning groove 23 of the first end plate is opposite to the first positioning groove 22 of the second end plate.

[0113] The first end plate and the second end plate play the role of limiting the position of the blade battery 6 and preventing errors.

[0114] The following takes the first end plate as an example to describe the structure of the first end plate in detail. The first end plate includes a plate body 21, a first positioning groove 22, and a second positioning groove 23. The plate body 21 can be a flat plate, which has low manufacturing cost, light weight, and is easy to install. The first positioning grooves 22 are arranged in a row on the plate body 21; the second positioning grooves 23 are arranged in a row on the plate body 21; the first positioning grooves 22 and the second positioning grooves 23 are arranged alternately. The length of the first positioning groove 22 is shorter than the length of the second positioning groove 23; wherein a second positioning groove 23 is arranged between every two first positioning grooves 22. The first positioning groove 22 is relatively short, and the first positioning groove 22 is used to place the end of the blade battery 6 where the injection hole is not provided. The second positioning groove 23 is relatively long, and the first positioning groove 22 is used to place the end of the blade battery 6 where the injection hole is provided. Because a sealing plate 63 is provided at the injection hole, and the sealing plate 63 protrudes from the end cover of the blade battery 6, and the distance between the positive pole 61, the negative pole 62, and the sealing plate 63 is relatively long, a second positioning groove 23 is used to accommodate one end of the blade battery 6 with the injection hole.

[0115] That is, the first positioning grooves 22 of the first end plate and the second end plate are configured to accommodate the positive pole 61 and the negative pole 62 of the blade battery 6. The second positioning grooves 23 are configured to accommodate the positive pole 61, the negative pole 62 of the blade battery 6 and the sealing plate 63 at the injection hole.

[0116] In some embodiments, one end of the first positioning groove 22 and the second positioning groove 23 extend to the edge of the first end plate and the second end plate, so one end of the first positioning groove 22 and one end of the second positioning groove 23 are open. The other end of the first positioning groove 22 and the other end of the second positioning groove 23 do not extend to the edge of the first end plate and the second end plate, so they are not open. Since one end of the first positioning groove 22 and one end of the second positioning groove 23 are open, when installing the first end plate and the second end plate, the first end plate and the second end plate can be directly inserted at both ends of the blade battery 6, which is efficient and simple to operate.

[0117] After the above step S200, the blade batteries 6 are arranged as a whole to facilitate subsequent operations.

[0118] Step S300: fix all blade batteries 6 to be connected.

[0119] Until step S300, only the bottom plate fixture 1 is in contact with the blade battery 6, and the end plate fixture 2 has been removed. The bottom plate fixture 1 is mainly in contact with the bottom and lower part of the blade battery 6. The fixing frame 4 is in contact with the side of the blade battery 6. The top of the blade battery 6 is empty and is not restricted by the fixture or other components.

[0120] Specifically, the blade batteries 6 are fixedly connected in the following manner: first, glue is applied on the top of each blade battery 6; second, a fixing plate 7 is placed on the top of each blade battery 6; finally, each blade battery 6 is fixedly connected to the fixing plate 7. The fixing plate 7 is a flat plate, and the top of each blade battery 6 is fixedly connected to the fixing plate 7 by glue. There is a certain gap between two adjacent blade batteries 6, which makes the heat dissipation performance of the blade battery 6 better and can limit the expansion degree of the blade battery 6.

[0121] After the above step S300, in order to make the fixed connection between the fixing plate 7 and the blade battery 6 more stable, in some embodiments, after the step of placing the fixing plate 7 on the top of each blade battery 6, the following steps are further included: placing a weight 9 on the top of the fixing plate 7, and after a set time, removing the weight 9 to fix each blade battery 6 to the fixing plate 7. The set time is, for example, 12 hours to 24 hours.

[0122] Step S400, use the connecting piece 10 to electrically connect the poles of two adjacent blade batteries 6. After each blade battery 6 is placed side by side, the fixing frame 4 is installed on the blade battery 6. The fixing frame 4 is used to support the connecting piece 10 before welding, so that the welding operation of the connecting piece 10 is more convenient. After the connecting piece 10 is welded, there is no need to remove the fixing frame 4. Then the connecting piece 10 is welded and fixed to the blade battery 6. There are a large number of connecting pieces 10. In order to make the connecting piece 10 conveniently fixed near the positive pole 61 and the negative pole 62 of the blade battery 6, fixing the connecting piece 10 mainly includes the following steps: First, install the fixing frame 4 on the blade battery 6 from which the end plate tooling 2 has been removed. Because the end plate tooling 2 has been removed, there are no other components on the top of the blade battery 6, and the fixing frame 4 can be easily installed.

[0123] See also Fig.10 and Fig.11 The fixing frame 4 includes a vertical plate 41, a plurality of pairs of blocks 42 disposed on the vertical plate 41, and a through hole or groove 40 is disposed between a pair of blocks 42 to accommodate components protruding from the end plate, such as the positive pole 61, the negative pole 62, and the sealing plate 63. The fixing frame 4 can be an injection molded part, and the fixing frame 4 is light in weight and easy to install.

[0124] Next, the connecting piece 10 is mounted on the fixing frame 4 , and the fixing frame 4 supports the connecting piece 10 . One connecting piece 10 is mounted between each pair of the clamping blocks 42 .

[0125] Finally, the connecting piece 10 is welded and fixed to the pole of the blade battery 6 .

[0126] After the connecting piece 10 is welded and fixed, there is no need to remove the fixing frame 4. In addition to supporting the connecting piece 10, the fixing frame 4 can also play a certain supporting and positioning role for the blade battery 6.

[0127] Step S500 , transporting the fixed blade battery 6 into the box 8 .

[0128] There are multiple ways to implement the above step S500. One way is to directly use the first sling 3 to transport and place the fixed blade battery 6 inside the box. Another way is to use the second sling 5 and the third sling in combination, the second sling 5 is mainly used for transfer transportation, and the third sling is mainly used to place the fixed blade battery 6 inside the box.

[0129] Fig.13 A schematic structural diagram of a first hanger 3 used in the blade battery packing method provided in an embodiment of the present invention. Fig.14 This is a schematic diagram of using the first sling 3 to place the blade battery 6 into the box body in the blade battery packaging method provided by an embodiment of the present invention. Fig.13 and Fig.14 , the following describes a method of using the first sling 3 to achieve transfer and boxing.

[0130] In some embodiments, the step of transporting the fixed blade batteries 6 into the box specifically includes: using the first sling 3 to transport the fixed blade batteries 6 into the box; and taking out the first sling 3.

[0131] See also Fig.13 In some embodiments, the first sling 3 includes a first frame 31, a first limit plate 32, a first tensioning member 33, and a plurality of first suction cups 34. The first limit plates 32 are arranged in pairs, and each first limit plate 32 is fixedly connected to the first frame 31. The first tensioning member 33 is fixed between two first limit plates 32 arranged in pairs to limit the distance between the two first limit plates 32. Each first suction cup 34 is fixedly connected to the first frame 31, and the first suction cup 34 is configured to adsorb the top of the fixed plate 7.

[0132] See also Fig.13 , the selection of the first suction cup 34 must meet the following requirements: 1) The bearing capacity of the first suction cup 34 is greater than the module weight * (1 + safety factor), and the safety factor is between 0.5 and 3.5. 2) The first suction cup 34 needs to cover as much area of ​​the fixing plate 7 as possible, and the coverage area of ​​the first suction cup 34 accounts for more than 25% of the bottom projection area of ​​the blade battery 6 module, and the blade batteries 6 covered by the first suction cup 34 should not be less than 55% of the total number of blade batteries 6 in the module.

[0133] The first hanger 3 uses the first suction cup 34 to absorb the fixing plate 7. There is no support at the bottom of the blade battery 6. Therefore, after the first hanger 3 puts the blade battery 6 into the box, the first suction cup 34 can be directly removed.

[0134] Fig.15 This is a schematic diagram of the structure of the second hanger 5 used in the blade battery packaging method provided in an embodiment of the present invention. Fig.15 The following describes a method of using the second sling 5 and the third sling to cooperate to achieve transfer and boxing.

[0135] In some embodiments, the step of transporting the fixed blade batteries 6 into the box specifically includes: using the second sling 5 to transport the fixed blade batteries 6 to the vicinity of the box; removing the second sling 5; using the third sling to transport the fixed blade batteries 6 into the box; and taking out the third sling.

[0136] See also Fig.15 In some embodiments, the second sling 5 includes a second frame 51, a second limiting plate 52, and a second tensioning member 53. The second limiting plates 52 are arranged in pairs, and each second limiting plate 52 is fixedly connected to the second frame 51; each second limiting plate 52 includes a first plate 21 and a bending section located at the bottom of the first plate 21; the bending section is configured to be placed at the bottom of the blade battery 6 to support the blade battery 6; the bending section is fixedly connected to the first plate 21 or is integral. The second tensioning member 53 is fixed between the second plates 21 of the two second limiting plates 52 arranged in pairs to limit the distance between the two second limiting plates 52.

[0137] The second sling 5 can hold the bottom of the blade battery 6, so the second sling 5 can be used to transport the blade battery 6. If the second sling 5 is used to put the blade battery 6 into the box, it may be difficult to remove the second sling 5 from the box. The third sling is only fixedly connected to the fixing plate 7 at the top of the blade battery 6, and the third sling is not connected to the bottom of the blade battery 6, so the third sling can be easily removed.

[0138] The second sling 5 is divided into two parts: a lower hook part and an upper hoisting part. The second limit plate 52 and the second tension member 53 serve as the hook part. The second frame 51 serves as the hoisting part. The second frame 51 and the second limit plate 52 are connected together by ropes.

[0139] The second limiting plate 52 is symmetrically provided with lifting holes 511 on its side, and the limiting plate is connected to the second limiting plate 52 by bolts. The limiting plate and the bolts form a limiting mechanism 512. The position of the limiting mechanism 512 corresponds to the position of the side observation hole 513 of the second limiting plate 52. The bending section is fixed with a buffer pad 514, which can reduce the mode of the blade battery 6.

[0140] The upper lifting tooling includes a lifting ring 521, a second frame 51, a lifting rope 523 and a lifting hook 524. The cushioning pad 514 is inserted into the bottom of the blade battery 6, the lifting hook 524 is installed in the lifting hole 511 on the side, and the limiting mechanism 512 is fixedly connected to the second limiting plate 52 by bolts to complete the fixing of the entire tooling. When lifting the blade battery 6, the blade battery 6 is first placed on the bending section, and then the second limiting plate 52 is installed.

[0141] The third sling has the same structure as the first sling 3. In some embodiments, the third sling includes a third frame, a third limit plate, a third tensioning member, and a plurality of second suction cups. The third limit plates are arranged in pairs, and each third limit plate is fixedly connected to the third frame. The third tensioning member is fixed between two third limit plates arranged in pairs to limit the distance between the two third limit plates. Each second suction cup is fixedly connected to the third frame, and the second suction cup is configured to adsorb the top of the fixed plate 7.

[0142] In some embodiments, the step of using a third sling to transport the fixed blade batteries 6 into the box includes: using a second suction cup to adsorb the fixing plate 7; lifting the blade batteries 6; and transporting the blade batteries 6 into the box.

[0143] After the second suction cup is installed, the blade battery 6 is hoisted above the box 6. The distance between the bottom surface of the module and the highest point directly below should not be greater than the safe drop height of the blade battery. The safe drop height of the battery is determined according to industry standards. At this time, the module is removed from the transfer tooling by the sling 35, the limit mechanism 512 is released, the transfer tooling is evacuated, and the sling 35 is slowly lowered to complete the operation of inserting the blade battery 6 into the box.

[0144] In some embodiments, the blade battery packaging method further includes the following steps: installing other components in the box.
