[0002] With the development of new energy, the energy density of battery packs is gradually increasing. The use of multiple battery cells directly integrated into a battery pack (CTP) technology is the future development direction of the electric vehicle industry. CTP technology simplifies the manufacturing process from battery-module-pack to battery-pack, eliminating the intermediate module step, significantly reducing the weight of the pack and thus increasing energy density.

[0003] In related technologies, stacking tooling stacks multiple battery cells in rows, solidifies the multiple rows of battery cell stacks into a whole, and then puts them into a whole package. An intermediate plate is set between two adjacent rows of battery cells, and the intermediate plate and the battery cells are bonded with adhesive to allow the battery cells to be stacked and directly form a whole package.

[0033] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0034] See also Figure 1A battery cell stacking tool according to a specific embodiment of the present invention includes a device base 1, a stacking platform 2, and a stacking mechanism. The stacking mechanism and the stacking platform 2 are fixedly installed on the device base 1. The stacking mechanism includes a first blocking component 31 and a first pushing component 32. The first blocking component 31 and the first pushing component 32 are relatively arranged on both sides of the stacking platform 2; to this end, technicians can place multiple battery cells on the stacking platform 2 in an orderly manner, and use the first pushing component 32 to push the multiple battery cells toward the first blocking component 31. The first blocking component 31 in turn blocks the battery cells, thereby making the multiple battery cells close to each other and fit tightly on the stacking platform 2, so as to finally realize multi-battery cell stacking and form a battery pack.

[0035] More specifically: See Figure 2 In this embodiment, the device base 1 is a flat plate suspended on a workbench, and is provided with a plurality of mounting holes 11 on the device base 1. The plurality of mounting holes 11 are distributed in a grid pattern on the device base 1, and the distance between any two adjacent mounting holes 11 in the upper and lower directions or in the left and right directions is the thickness of a battery cell. The first blocking component 31 and the first pushing component 32 are correspondingly provided with threaded mounting structures. The first blocking component 31 and the first pushing component 32 are fixedly mounted at the mounting holes 11 on both sides of the stacking platform 2 through the threaded mounting structures, so as to cooperate with each other on both sides of the stacking platform 2 to stack the battery cells. The technician can also remove the first blocking component 31 and / or the first pushing component 32 through the threaded mounting structure and fix the first blocking component 31 and / or the first pushing component 32 to other mounting holes 11 on the device base 1 to adjust the distance between the first blocking component 31 and the first pushing component 32, so that the stacking mechanism can be adapted to the stacking manufacturing requirements of newly designed battery packs.

[0036] In this embodiment, the threaded mounting structure is a bolt vertically mounted on the first blocking component 31 or the first pushing component 32, and a nut threaded onto the bolt. The cap and nut of the bolt are respectively located on the upper and lower sides of the device base 1 and cooperate with each other to clamp and fix the device base 1 at the mounting hole 11, thereby fixing the first blocking component 31 or the first pushing component 32. In addition, to accommodate battery packs of different sizes, the stacking platform 2 is also fixedly mounted at the mounting hole 11 in the central area of ​​the device base 1 through a threaded mounting structure. The stacking platform 2 also has a variety of sizes and models. Technicians can disassemble and replace the stacking platform 2 with a slightly larger size according to the size of the newly designed battery pack to prevent the stacked cells from falling off the stacking platform 2.

[0037] Further, see Figure 3In this embodiment, the first blocking assembly 31 includes a first base 311, an adjustment slide rail 312, a first baffle 313, and a locking assembly 314. The first base 311 is a rectangular bottom plate. The first base 311 is fixedly mounted on the device base 1 through multiple sets of threaded mounting structures. Two adjustment slide rails 312 are arranged side by side on the first base 311. The setting direction of the two adjustment slide rails 312 is consistent with the stacking and closing direction of the battery cells. The first baffle 313 is an L-shaped plate. Two sliders are correspondingly arranged at the bottom of the first baffle 313. One slide rail is correspondingly slidably connected to one adjustment slide rail 312. The first baffle 313 is correspondingly connected to the two adjustment slide rails 312 at the same time through two sliders. 12 corresponds to the sliding connection, and there are two groups of locking components 314. The two groups of locking components 314 are fixedly mounted on the first base 311, and the two groups of locking components 314 are respectively arranged on the sides of the two adjusting slide rails 312; taking one of the locking components 314 as an example, the locking component 314 includes a locking bar 3141 arranged parallel to the adjusting slide rail 312, a plurality of locking sockets 3142 equidistantly opened on the locking bar 3141, and a locking plug 3143 inserted on the first baffle 313 and inserted into the corresponding locking socket 3142 to cooperate with locking the first baffle 313. The spacing between adjacent locking sockets 3142 is the thickness size of a battery cell.

[0038] In this regard, during the design and development process of the battery pack, when the size specifications of the next battery pack sample to be stacked and manufactured are relatively close to the size specifications of the previous battery pack sample, technicians do not need to disassemble the first blocking assembly 31 and the first pushing assembly 32. Instead, they can pull out the locking bar 3141 upward to unlock the sliding function of the first baffle 313. After sliding and adjusting the first baffle 313 to a certain position, the locking bar 3141 is passed through the first baffle 313 to be inserted into another corresponding locking hole 3142 to lock the first baffle 313 again so that the stacking mechanism can adapt to the size specifications of the next battery pack sample.

[0039] In addition, Figure 1 Taking the shown position as an example, in order to prevent the multiple battery cells from being unable to be pushed tightly together when the first push plate 321 of the first pushing component 32 moves to the lower right to the end of the stroke, technicians can also use the locking component 314 to further adjust the position of the first baffle 313 to ensure that the battery cell stacking process can be completed within the pushing stroke of the first pushing component 32 to ensure the quality of the battery cell stacking.

[0040] Further, please participate Figure 4 ,by Figure 4Taking the orientation shown in as an example, in this embodiment, the first pushing assembly 32 includes a first push plate 321, a screw rod 322, and a screw rod seat 323. A raised structure is provided at the left middle position of the screw rod seat 323, and a threaded hole is horizontally opened on the raised structure. The screw rod 322 is horizontally screwed in the threaded hole. The right end of the screw rod 322 is fixedly connected to the first push plate 321, and the left end is provided with a rotating handle. To this end, the technician can manually turn the rotating handle to make the screw rod 322 perform a spiral feed motion, thereby driving the first push plate 321 to perform a linear displacement to push multiple battery cells to be stacked close to each other.

[0041] Moreover, support arms are provided on the upper and lower sides of the first push plate 321, and guide rails 324 are provided under the support arms. A guide slide 325 is correspondingly provided on the screw seat 323. The guide rails 324 and the guide slide 325 cooperate with each other to limit the position so that the first push plate 321 can move stably in a straight line.

[0042] Further, see Figure 1 and Figure 1 Taking the shown orientation as an example, a second pushing component 52 is provided on the lower left side of the stacking platform 2, and a second blocking component 51 is provided on the upper right side. The second pushing component 52 and the second blocking component 51 are combined to form a side regularization mechanism to keep multiple battery cells flush along the pushing direction of the stacking mechanism.

[0043] Specifically, see Figure 5 The second blocking assembly 51 includes a second baffle 511 and a second base 512. The second base 512 is fixedly mounted on the device base 1 through a threaded mounting structure. The second baffle 511 is vertically fixedly mounted on the side of the second base 512 to form a blocking structure.

[0044] See also Figure 6 The second pushing assembly 52 includes a second pushing plate 521, a pushing rod 522, a quick clamp 523, and a pushing base 524. The pushing base 524 is detachably fixed to the equipment base 1 through a threaded mounting structure. The quick clamp 523 is arranged in the middle of the pushing base 524, and the pushing rod 522 is arranged horizontally, and one end of the pushing rod 522 is fixedly connected to the second pushing plate 521 and the other end is connected to the quick clamp 523. The pushing rod 522 is also movably inserted into the limiting sleeve on the upper end surface of the quick clamp 523; to this end, the technician can manually press the lever above the quick clamp 523, and then push the pushing rod 522 to extend horizontally axially in the limiting sleeve to push the second pushing rod 522 to move toward the second baffle 511, thereby pushing the multiple battery cells on the stacking platform 2 to be flush with each other; the technician can also go on the stage to push the lever to make the pushing rod 522 retract, so as to facilitate the normal operation of the stacking mechanism and replace the stacked battery cells.

[0045] Similarly, in order to ensure that the second push plate 521 can make stable linear reciprocating displacement under the push of the push rod 522, two guide rails 526 are also provided on the push base 524. The rear lower part of the second push plate 521 is fixedly installed with two guide slides 525 through a tripod. The guide slides 525 and the guide rails 526 cooperate with each other to guide and limit the linear displacement of the second push plate 521.

[0046] In this embodiment, the stacking platform 2 is assembled with the second blocking assembly 51 . Second blocking assemblies 51 of different lengths are correspondingly provided on the upper right side of different types of stacking platforms 2 and are mounted on the second base 512 .

[0047] In addition, in this embodiment, insulating blocks 4 are provided on the surfaces of the first baffle 313, the first push plate 321, and the second push plate 521 that are in contact with the battery cells. Although the shapes and sizes of the insulating blocks 4 on the first baffle 313, the first push plate 321, and the second push plate 521 are different, their function is to insulate and isolate the battery cells from the stacking tooling to avoid leakage installation problems.

[0048] Any matters not mentioned above are applicable to the prior art.

[0049] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents; and such modifications or replacements do not deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
