[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] When splicing multiple battery cells, irregularly shaped circuit boards are sometimes used to achieve series and parallel connections of multiple cells to accommodate the arrangement of multiple cells. For example, Figure 4 As shown, the circuit board includes a main control board 230 and a flexible circuit board 200 electrically connected to the main control board 230. The flexible circuit board 200 is used to connect multiple (6 cells are shown exemplarily in the figure) battery cells 300 in series. The flexible circuit board 200 includes a first flexible plate 210 extending along a first direction X and two second flexible plates 220 extending along a second direction Y. The two second flexible plates 220 are respectively connected to the two ends of the first flexible plate 210 along the first direction X. The first flexible plate 210 is used to solder to the tabs of two battery cells 300, and each second flexible plate 220 is used to solder to the tabs of two battery cells 300. The main control board 230 and the flexible circuit board 200 are generally configured in a "mountain" shape.

[0033] Before soldering the flexible circuit board 200 to the tabs of each battery cell 300, the flexible circuit board 200 needs to be pre-positioned. The flexible circuit board 200 is pre-attached to each battery cell 300 using double-sided adhesive, and the flexible circuit board 200 is pressed down to activate the adhesive. Due to the structure and material characteristics of the flexible circuit board 200, pressing down can easily cause the second flexible boards 220 on both sides to become misaligned, resulting in the soldering points on the second flexible boards 220 not being properly aligned with the tabs and thus failing to solder. Alternatively, even if soldering is barely achieved, the stress caused by the misalignment of the second flexible boards 220 on both sides can pull on the soldering points, easily leading to the risk of breakage at the soldering points and poor reliability.

[0034] In response, this utility model uses a guiding mechanism to guide the two second flexible plates 220 from a skewed state to a corrected state. In the corrected state, the second flexible plates 220 can be precisely aligned with the tabs of the battery cell 300, which facilitates welding. Furthermore, after welding, the second flexible plates 220 are free from stress and do not pull on the welding points, thereby ensuring the reliability of the connection.

[0035] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0036] According to an embodiment of the present invention, a guiding mechanism 100 is provided for guiding a flexible circuit board 200. The flexible circuit board 200 is used to connect multiple battery cells 300. The flexible circuit board 200 includes a first flexible plate 210 and two second flexible plates 220 connected to opposite ends of the first flexible plate 210 along a first direction X. The second flexible plates 220 extend along a second direction Y, which is perpendicular to the first direction X. The second flexible plates 220 have a skewed state and a corrected state. In the corrected state, the second flexible plates 220 are used to weld to the corresponding battery cells 300.

[0037] The guiding mechanism 100 includes two guiding components 21 and a driving component 22. The two guiding components 21 are spaced apart along a first direction X. The driving component 22 is used to drive the two guiding components 21 to move along a third direction Z and to move closer to or further away from each other along the first direction X. The third direction Z is perpendicular to the first direction X and the second direction Y. When the guiding components 21 move along the third direction Z, they can reach between the two second flexible plates 220. When the two guiding components 21 move away from each other along the first direction X, they can guide the two second flexible plates 220 from a skewed state to a corrected state.

[0038] The skewed state of the second flexible plate 220 refers to the stress (rebound force) that the second flexible plate 220 has due to its skewness, which allows it to recover to its initial state. The corrected state of the second flexible plate 220 refers to the second flexible plate 220 being in a near-natural state, with almost no stress (rebound force). Figure 5This illustrates the situation where the two second flexible plates 220 are tilted inwards towards each other (pigeon-toed). Figure 6 The diagram shows two second flexible plates 220 perpendicular to the first flexible plate 210. It is understood that the corrected state of the second flexible plates 220 can also be other stress-free natural states.

[0039] As an example, refer to Figure 4 After the multiple battery cells 300 are arranged, the main control board 230 and the flexible circuit board 200 are placed in their corresponding positions, and then the flexible circuit board 200 is pre-fixed. Specifically, the first flexible board 210 can be pasted onto the two middle battery cells 300 along the first direction X, and the two second flexible boards 220 can be pasted onto the two battery cells 300 on both sides along the first direction X. At this time, due to the pre-fixation of the flexible circuit board 200, the two second flexible boards 220 on both sides may appear to be skewed inward. Figure 5 (As shown). To this end, the guiding mechanism 100 is activated, and the driving component 22 drives the guiding component 21 to move along the third direction Z from its initial position between the two second flexible plates 220. Then, the driving component 22 drives the two guiding components 21 to move away from each other, causing the two guiding components 21 to contact and actuate the two second flexible plates 220 respectively, thus changing the two second flexible plates 220 from a skewed state to a corrected state. Figure 6 As shown), in this corrected state, the second flexible plate 220 is welded and fixed to the electrode tab of the cell 300.

[0040] It is worth noting that after the second flexible plate 220 is aligned to the calibration state, it can remain in the calibration state due to the adhesive relationship between the second flexible plate 220 and the battery cell 300. At this time, the driving component 22 can drive the two alignment components 21 to move closer to each other, causing the two alignment components 21 to detach from the second flexible plate 220. The driving component 22 then drives the two alignment components 21 to return to their initial positions along the third direction Z. Of course, the two alignment components 21 may also remain aligned with the second flexible plate 220 after it is aligned to the calibration state.

[0041] By moving the two guiding components 21 away from each other, the two second flexible plates 220 are guided from a skewed state to a corrected state. This not only enables precise alignment of the second flexible plates 220 with the tabs of the battery cell 300, facilitating welding and improving manufacturing efficiency, but also ensures that the second flexible plates 220 are in a natural corrected state after welding, without springback stress, and the welding points are not stretched.

[0042] In some embodiments, the guiding mechanism 100 further includes a first fixing frame 23, on which a first slide rail 231 extending along a first direction X is disposed; the guiding assembly 21 includes a guiding bracket 211 and a guiding block 212, the guiding bracket 211 being slidably connected to the first slide rail 231, the guiding block 212 being connected to the guiding bracket 211, and the guiding block 212 being used to contact the second flexible plate 220; the driving assembly 22 includes a first driving member 221 disposed on the first fixing frame 23, the first driving member 221 being used to drive the guiding brackets 211 of the two guiding assemblies 21 to move closer to or further away from each other along the first slide rail 231. The first fixing frame 23 can be slidably connected to the first slide rail 231 by a slider.

[0043] The first drive element 221 can simultaneously drive two guide brackets 211 to move closer to or further away from each other along the first slide rail 231. The first drive element 221 can be, for example, a bidirectional drive cylinder.

[0044] There can be two first driving elements 221 and two first slide rails 231. The two first driving elements 221 respectively drive the two guide brackets 211 to move closer to or further away from each other along their respective first slide rails 231. The first driving element 221 can be a one-way cylinder.

[0045] The first driving member 221 drives the two guide brackets 211 to move closer to or further away from each other along the first slide rail 231, thereby causing the guide blocks 212 to move closer to or further away from each other along the first slide rail 231 together. This improves the smoothness of the movement of the guide components 21 closer to or further away from each other.

[0046] In some embodiments, an elastic element 213 is provided between the guide bracket 211 and the first driving member 221. One end of the elastic element 213 is connected to the guide bracket 211, and the other end is connected to the driving end of the first driving member 221. The elastic element 213 may be a spring.

[0047] By setting the elastic element 213, when the first driving element 221 drives the two guiding brackets 211 to move away from each other, the guiding block 212 can apply a moderate and uniform elastic linear force to the second flexible plate 220, preventing the second flexible plate 220 from being over-stressed and damaged, and improving the guiding reliability.

[0048] In some embodiments, the guide block 212 is detachably connected to the guide bracket 211.

[0049] The guide block 212 can be detachably connected to the guide bracket 211 via fasteners. The fasteners can be bolts, screws, etc.

[0050] The guide block 212 is detachably connected to the guide bracket 211, making it easy to replace the guide block 212 to adapt to the guidance of different types of flexible circuit boards.

[0051] In some embodiments, there are two first slide rails 231, and two guide brackets 211 are slidably connected to the two first slide rails 231 respectively; there are two first drive members 221, and the drive ends of the two first drive members 221 are connected to the two guide brackets 211 respectively, and the two first drive members 221 are located between the two guide brackets 211.

[0052] The two first driving components 221 are located between the two guide brackets 211, which can avoid the risk of the two guide brackets 211 colliding with each other, and utilize the space between the two guide brackets 211, making the overall structure of the guide mechanism 100 more compact and reducing space occupation.

[0053] In some embodiments, the guiding mechanism 100 further includes a second fixing frame 24, on which a second slide rail 241 extending along a third direction Z is provided, and the first fixing frame 23 is slidably connected to the second slide rail 241; the driving assembly 22 further includes a second driving member 222, which is connected to the first fixing frame 23 and is used to drive the first fixing frame 23 to move along the second slide rail 241.

[0054] The second drive component 222 can be a servo mechanism, such as a servo motor working with a bolt and nut assembly to achieve the lifting and lowering of the first fixed frame 23 along the third direction Z.

[0055] The second driving component 222 drives the first fixed frame 23 to move along the second slide rail 241, and the two guiding components 21 also follow the first fixed frame 23 to move along the second slide rail 241, so that the two guiding components 21 reach between the two second flexible plates 220.

[0056] In some embodiments, the guiding mechanism 100 further includes a detection component (not shown) for detecting the torque and / or state of the second flexible plate 220 when the guiding component 21 guides the second flexible plate 220.

[0057] The detection component may include a pressure sensor disposed on the alignment component 21. The pressure sensor detects the torque when the second flexible plate 220 is aligned, and obtains the force applied to the second flexible plate 220 so as to make timely adjustments and avoid damage to the second flexible plate 220.

[0058] The detection component may also include a vision camera, which can detect the state of the second flexible plate 220 in real time, i.e. whether it is in a calibration state, to prevent over-calibration and over-shaping of the second flexible plate 220.

[0059] In some embodiments, refer to Figure 2The guiding mechanism 100 also includes a tooling fixture 10, which includes a support platform 11 for supporting the battery cell 300. The support platform 11 is provided with a clearance opening 111. The guiding component 21 is located below the support platform 11. When the guiding component 21 moves along the third direction Z, it can pass through the clearance opening 111 to reach between the two second flexible plates 220.

[0060] The clearance opening 111 is used for the guide assembly 21 to pass through to reach between the two second flexible plates 220, while the clearance opening 111 has space for the guide assembly 21 to move along the first direction X.

[0061] When the second flexible plate 220 needs to be aligned, the alignment component 21 passes through the clearance opening 111 to reach between the two second flexible plates 220. When alignment is not needed, the alignment component 21 exits from the clearance opening 111, without interfering with the components on the support platform 11, thus improving convenience.

[0062] When the guiding component 21 is driven by the driving component 22 to move along the third direction Z, it can pass through the clearance opening 111 on the support platform 11 to reach between the two second flexible plates 220, which can effectively adjust for different product process types to improve adaptability.

[0063] In some embodiments, the tooling fixture 10 further includes a pressure plate 12, which is rotatably connected to the support platform 11 and is used to fix the battery cell 300 between the support platform 11 and the pressure plate 12.

[0064] There can be one or more pressure plates 12. When there are multiple pressure plates 12, the multiple pressure plates 12 correspond to multiple battery cells 300.

[0065] The pressure plate 12 can be automatically rotated by a rotary cylinder to fix the battery cell 300 between the support platform 11 and the pressure plate 12.

[0066] The pressure plate 12 is rotatably connected to the support platform 11, which fixes the battery cell 300 between the support platform 11 and the pressure plate 12, thereby improving the stability of the battery cell 300 and thus improving the welding reliability of the flexible circuit board 200 and the battery cell 300.

[0067] In some embodiments, the support platform 11 is provided with a first battery cell fixing position 101, a second battery cell fixing position 102, a third battery cell fixing position 103 and a fourth battery cell fixing position 104 arranged sequentially at intervals along the first direction X; the gap between the first battery cell fixing position 101 and the second battery cell fixing position 102, and the gap between the third battery cell fixing position 103 and the fourth battery cell fixing position 104 are respectively provided with clearance openings 111; the gap between the second battery cell fixing position 102 and the third battery cell fixing position 103 is used to place the main control board 230 that is electrically connected to the flexible circuit board 200.

[0068] As an example, the first cell fixing position 101 can fix two smaller cells 300, the second cell fixing position 102 and the third cell fixing position 103 can each fix one larger cell 300, and the fourth cell fixing position 104 can fix two smaller cells 300. The first flexible plate 210 can be welded to the cells 300 on the second cell fixing position 102 and the third cell fixing position 103, and the two second flexible plates 220 can be welded to the cells 300 on the first cell fixing position 101 and the fourth cell fixing position 104, respectively, thereby connecting the six cells 300 in series and / or in parallel.
