Description

Technical Field

[0001] This invention relates to the field of lithium battery cell processing and positioning devices, and in particular to a high-efficiency and high-precision positioning mechanism for multiple cells simultaneously. Background Technology

[0002] In the battery cell manufacturing process, the accuracy and efficiency of cell positioning directly affect the quality and efficiency of subsequent processing steps, which in turn affects the overall processing quality and production efficiency of the battery pack.

[0003] Current technologies typically perform positioning and processing on a single battery cell at a time, followed by unified packaging after all cells have been processed. This not only results in low production efficiency but also leads to inconsistent performance. While there are devices capable of positioning and processing multiple cells simultaneously, these suffer from low positioning accuracy and poor applicability. Summary of the Invention

[0004] This invention provides a high-efficiency and high-precision positioning mechanism for synchronizing multiple battery cells, aiming to solve one or more of the above-mentioned technical problems. The specific solution is as follows:

[0005] A high-efficiency and high-precision positioning mechanism for synchronizing multiple battery cells includes:

[0006] A positioning platform, wherein several battery cell positioning units are arranged side by side in the X direction;

[0007] Several limiting components are disposed in the cell positioning unit to limit the first opposite corner of the cell housing;

[0008] The corner-pushing mechanism is arranged parallel to the diagonal side of the limiting component, and includes a driving component, a push plate disposed at the driving end of the driving component, and a plurality of pushing components arranged side by side on the push plate. The pushing components are arranged correspondingly to the limiting component, and press the second diagonal of the battery cell housing under the drive of the driving component, so that the battery cell housing is pressed and fixed between the limiting component and the pushing components.

[0009] Its beneficial effects are: a battery cell positioning unit can be set according to the number of battery cell housings that need to be positioned, and a corresponding push-angle mechanism can be set. The first opposite corner of the battery cell housing is limited by the limiting component, and the second opposite corner of the battery cell housing is pushed and fixed by the pushing component of the push-angle mechanism. Through the cooperation of multiple limiting components and push-angle mechanism, multiple battery cells can be positioned synchronously at the same time. The operation is simple and convenient, and the positioning accuracy and stability are high.

[0010] In some embodiments, the limiting assembly includes an X-limiting member and a Y-limiting member that are perpendicular to each other, and a first fixing plate is provided on one side of the bottom of the Y-limiting member.

[0011] The Y-limiting member has several second elongated holes in the X direction and is fixedly installed on the cell positioning unit through the second elongated holes, so that the position of the Y-limiting member is adjustable along the X direction;

[0012] The X-limiting member has several first elongated holes in the Y direction and is fixedly installed on the first fixing plate through the first elongated holes, so that the position of the X-limiting member is adjustable along the Y direction.

[0013] Its beneficial effects are: the positions of the X-limit and Y-limit components can be adjusted according to the size of the battery cell housing, making the positioning of the battery cell housing more accurate, improving the applicability of the synchronous positioning mechanism, and reducing production costs.

[0014] In some embodiments, the pushing component and the driving component are arranged in the same direction, and the pushing component includes a first adjusting component and a clamp. The first adjusting component includes a second fixing plate, a long plate, and a locking member.

[0015] The second fixing plate has several third elongated holes in the X direction and is fixedly installed on the push plate through the third elongated holes, so that the position of the second fixing plate can be adjusted relative to the push plate in the X direction;

[0016] The long plate has several fourth long holes along its length and is fixedly installed to the second fixed plate through the fourth long holes, so that the position of the long plate can be adjusted relative to the second fixed plate in the driving direction.

[0017] The locking member is used to lock the long plate onto the second fixing plate;

[0018] The clamp is located at the end of the long plate and is used to clamp the second opposite corner of the battery cell housing.

[0019] Its advantages are: the position of the clamp can be adjusted in the X direction and the driving direction of the drive assembly by the second fixing plate and the long plate respectively, so as to adapt to the clamping of battery cell housings of different sizes. The operation is simple and convenient, and the positioning accuracy is high.

[0020] In some embodiments, the locking member is L-shaped and disposed on one side of the long plate, including a vertical member and a horizontal member. The vertical member is detachably installed on the second fixing plate, and the horizontal member is pressed against the long plate, with the horizontal member perpendicular to the direction of the long plate. Its advantages are: the locking member cooperates with the long plate to adjust the angle of the pushing component; after the angle adjustment is completed, it is locked and fixed by the locking member. This allows the pushing component to be angled according to the shape and size of the battery cell housing, improving the applicability of the positioning mechanism, and providing simple and convenient operation with strong stability.

[0021] In some embodiments, the clamp includes a first clamping member, a second clamping member, and a connecting member. The connecting member is fixedly connected to the end face of the long plate. The first clamping member and the second clamping member are disposed opposite to each other on the end face of the connecting member for clamping the second diagonal corner of the battery cell housing.

[0022] In some embodiments, a second adjusting component is further provided between the first adjusting component and the chuck.

[0023] The second adjusting component includes a fixing block for fixing the long plate, a floating block for fixing the clamp, and a vertical plate for connecting the fixing block and the floating block.

[0024] Two upright plates are provided, located on both sides of the fixed block and the floating block respectively, including a first connecting end and a second connecting end. The first connecting end is fixedly disposed on the fixed block, and the floating block is rotatably disposed between the second connecting ends of the two upright plates via a rotating shaft. Both ends of the fixed block are also provided with elastic elements, and the free end of the elastic element abuts against the floating block, so that the clamp can float and adjust about the rotating shaft.

[0025] Its beneficial effects are as follows: Since the fixed block is fixedly set between the first connecting ends of the two upright plates, and the floating block is rotatably set between the second connecting ends of the two upright plates via a rotating shaft, the floating block can rotate relative to the fixed block about the rotating shaft as the axis of rotation. In addition, the setting of the elastic element makes the floating block relatively parallel to the fixed block when the force is uniform; when the force on the floating block is uneven, it can be finely adjusted relative to the fixed block to a certain extent. In use, the position of the clamp is first coarsely adjusted by the first adjusting component, and then the angle of the clamp is finely adjusted by the second adjusting component during the pushing of the component relative to the cell housing. This makes the positioning mechanism suitable for the synchronous positioning of cell housings of different sizes, and the positioning accuracy is more precise and firm.

[0026] In some embodiments, the push-angle mechanism further includes sliding components. Two sets of sliding components are provided, located on either side of the drive component. Each sliding component includes a slide rail and a slider that slides relative to the slide rail. The slide rail is aligned with the drive component, and the slider is fixedly connected to the push plate. The beneficial effect is that the slider of the sliding component moves synchronously with the drive component, allowing the push plate to be pushed forward stably along the drive direction. This, in turn, allows multiple pushing components arranged side-by-side on the push plate to synchronously push and secure the second opposite corner of the battery cell housing, making the positioning of the battery cell housing more stable and reliable.

[0027] In some embodiments, the push-angle mechanism further includes a buffer assembly comprising a stop and a buffer. The stop is disposed at the end of the push plate and is perpendicular to the long plate, while the buffers are disposed on both sides of the stop. Its beneficial effect is to buffer the impact of the push-angle mechanism's movement, thereby preventing deformation of the battery cell casing.

[0028] In some embodiments, the upright plate is T-shaped, including a first T-shaped component and a second T-shaped component vertically disposed in the middle of the first T-shaped component. The first T-shaped component is fixed to both sides of the fixing block by screws. The second T-shaped component has a first through hole, and the floating block has a second through hole in its middle. The rotating shaft is inserted into the first and second through holes, allowing the floating block to be rotatably connected between the second T-shaped components. Its advantages are: the T-shaped upright plate structure makes the structure of the pushing assembly simpler and lighter, and the clamp fixation more stable.

[0029] In some embodiments, the multiple cell synchronization positioning mechanism further includes a controller and a position sensor. The controller is communicatively connected to both the drive assembly and the position sensor, and can control the start and stop of the drive assembly based on the sensing signal from the position sensor. The advantages are that the inclusion of the controller and position sensor results in a high degree of automation and intelligence in the cell synchronization positioning mechanism of this application, significantly improving positioning accuracy.

[0030] The beneficial effects of the present invention are: the positioning mechanism of the present invention has a reasonable structural design and is simple and convenient to operate. The first opposite corner of multiple battery cell housings arranged side by side is limited by the limiting component, and the second opposite corner of the battery cell housing is simultaneously pushed by the pushing corner mechanism to achieve synchronous clamping and positioning of multiple battery cells. This results in high consistency and accuracy of battery cell positioning, improves production efficiency and yield, and reduces production costs. Attached Figure Description

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0037] Combination Figure 1 To better illustrate the various components in this embodiment, a two-dimensional concept of X and Y axes is used. The distribution direction of the cell positioning unit 11 is taken as the X-axis direction (X direction), and the longitudinal direction perpendicular to the X-axis is taken as the Y-axis direction (Y direction).

[0038] Combination Figure 1-3. An embodiment of the present invention provides a high-efficiency and high-precision positioning mechanism for multiple battery cells, including a positioning platform 1, several limiting components 2, and a pushing angle mechanism 3. Several battery cell positioning units 11 are arranged side-by-side along the X-direction on the positioning platform 1. The limiting components 2 are disposed on the battery cell positioning units 11 and are used to limit the first opposite corner of the battery cell housing. The pushing angle mechanism 3 is arranged parallel to one diagonal side of the limiting components 2 and is used to synchronously push and tighten the second opposite corner of the battery cell housing. It includes a driving component 31, a push plate 32 disposed on the driving end of the driving component 31, and several pushing components 33 arranged side-by-side on the push plate 32. The pushing components 33 press and tighten the second opposite corner of the battery cell housing under the drive of the driving component 31. Since the pushing components 33 are arranged side-by-side on the push plate 32, they can synchronously push and tighten the second opposite corner of the battery cell housing under the drive of the driving component 31, together with the limiting components 2 used to limit the first opposite corner of the battery cell housing, to press and fix the battery cell housing, thereby achieving synchronous positioning of multiple battery cells. It should be noted that: In this embodiment, the battery cell housing is a cubic structure. The bottom surface of the battery cell housing is placed at the battery cell positioning unit 11. The first opposite corner of the battery cell housing is limited by the limiting component 2, and the second opposite corner of the battery cell housing is pushed by the pushing component 33. The first and second opposite corners are two opposite apex corners. Thus, the battery cell housing can be clamped and fixed by positioning the bottom surface and the two opposite apex corners. The stability is strong and the positioning accuracy is high.

[0039] Specifically, the limiting component 2 includes mutually perpendicular X-limiting member 21 and Y-limiting member 22. X-limiting member 21 limits the X-reference edge of the battery cell housing, and Y-limiting member 22 limits the Y-reference edge of the battery cell housing. In use, the first diagonal corner of the battery cell housing is placed within the limiting space formed by X-limiting member 21 and Y-limiting member 22. The X-reference edge of the battery cell housing is in contact with X-limiting member 21, and the Y-reference edge of the battery cell housing is in contact with Y-limiting member 22. To enable the positioning mechanism to be applicable to the positioning of battery cell housings of different sizes, the position of the limiting component 2 in this embodiment can be adjusted according to the size of the battery cell housing. Specifically, the Y-limiting member 22 has several second elongated holes 221 in the X direction, allowing the Y-limiting member 22 to be fixedly installed in the battery cell positioning unit 11 through the second elongated holes 221. This arrangement makes the position of the Y-limiting member 22 adjustable in the X direction. In addition, a first fixing plate 23 for fixing the X-limiting member 21 is provided on one side of the bottom of the Y-limiting member 22. The X-limiting member 21 has several first elongated holes 211 in the Y direction, so that the X-limiting member 21 can be fixedly installed on the first fixing plate 23 through the first elongated holes 211. This arrangement makes the position of the X-limiting member 21 adjustable in the Y direction. Therefore, the position of the limiting component 2 can be adjusted according to the size of the cell housing, and the positioning accuracy is higher.

[0040] Furthermore, combined with Figure 3 , 4As shown in Figure 5, in order to make the push-angle mechanism 3 adaptable to battery cell housings of different sizes, the push assembly 33 includes a first adjusting component 331 and a second diagonal clamp 332 for holding the battery cell housing. The first adjusting component 331 includes a second fixing plate 3311, a long plate 3312, and a locking component 3313. The second fixing plate 3311 has several third elongated holes 33111 in the X direction, so that the second fixing plate 3311 can be fixedly installed on the push plate 32 through the third elongated holes 33111. This arrangement makes the second fixing plate 3311... The position of the long plate 3312 can be adjusted relative to the push plate 32 in the X direction. Several fourth elongated holes 33121 are provided along the length of the long plate 3312, allowing the long plate 3312 to be fixedly mounted to the second fixed plate 3311 through these holes. This arrangement allows the position of the long plate 3312 to be adjusted relative to the second fixed plate 3311 in the driving direction. A locking member 3313 is used to lock the long plate 3312 onto the fixed plate 3311. A clamp 332 is located at the end of the long plate 3312 and is used to clamp the second opposite corner of the battery cell housing. Therefore, the position of the clamp 332 can be adjusted according to the size of the battery cell housing to be positioned, enabling the push-angle mechanism 3 to clamp and fix battery cell housings of different sizes.

[0041] Furthermore, in order to make the clamp 332 fit more tightly and the battery cell housing more stably, a second adjustment component 333 is also provided between the first adjustment component 331 and the clamp 332. The second adjustment component 333 includes a fixing block 3331 for fixing the connecting long plate 3312, a floating block 3332 for fixing the clamp 332, and a vertical plate 3333 for connecting the fixing block 3331 and the floating block 3332. The vertical plate 3333 is provided in two sets, located on both sides of the fixing block 3331 and the floating block 3332, respectively, including a first connecting end and a second connecting end. The first connecting end is fixedly set on the fixing block 3331, and the floating block 3332 is rotatably set between the second connecting ends of the vertical plate 3333 through the rotating shaft 3334. Preferably, the upright plate 3333 is T-shaped, including a first T-shaped component and a second T-shaped component vertically disposed in the middle of the first T-shaped component. The first T-shaped component is fixed to both sides of the fixed block 3331 by screws. The second T-shaped component has a first through hole, and the floating block 3332 has a second through hole in its middle. The rotating shaft 3334 passes through the first and second through holes, so that the floating block 3332 is rotatably connected between the second T-shaped components. Furthermore, elastic elements 3335 are provided at both ends of the fixed block 3331. The free end of the elastic element 3335 abuts against the floating block 3332, so that the clamp 332 can float and adjust about the rotating shaft 3334.

[0042] Furthermore, the locking member 3313 is L-shaped and is disposed on one side of the long plate 3312. It includes a vertical member (not shown in the figure) and a horizontal member 33131. The vertical member is fixedly disposed on the second fixing plate 3311, and the horizontal member 33131 is pressed on the long plate 3312, and the direction of the horizontal member 33131 is perpendicular to that of the long plate 3312.

[0043] Furthermore, the chuck 332 includes a first clamping member 3321, a second clamping member 3322, and a connecting member 3323. The connecting member 3323 is fixedly connected to the end face of the long plate 3312, and the first clamping member 3321 and the second clamping member 3322 are disposed opposite to each other on the end face of the connecting member 3323. In order to reduce the compression of the second diagonal of the battery cell housing during the clamping process, which would cause deformation of the second diagonal of the battery cell housing, the cross-sections of the first clamping member 3321 and the second clamping member 3322 are set as trapezoidal, and are spaced apart on both sides of the end face of the connecting member 3323.

[0044] In summary, the embodiments of the present invention use the limiting component 2 to limit the first opposite corner of the battery cell housing, and the pushing mechanism 3 to simultaneously push the second opposite corner of the battery cell housing, thereby achieving synchronous positioning of multiple battery cell housings. Furthermore, since the positions of the limiting component 2 and the clamp 332 are adjustable, the positioning mechanism of this application can be applied to battery cell housings of different sizes, reducing the cost of battery cell manufacturing and improving the accuracy of battery cell positioning.

[0045] Optionally, the cell positioning unit 11 is rectangular, including a first vertices and a second vertices opposite to the first vertices. A limiting component 2 is positioned at the first vertices, and a pushing mechanism 3 is parallel to the cell positioning unit 11 on the side near the second vertices. In use, the first opposite corner of the cell housing is placed at the first vertices of the cell positioning unit 11, and the second opposite corner is placed at the second vertices of the cell positioning unit 11. The first opposite corner of the cell housing is aligned with the limiting component 2. Then, the pushing mechanism 3 is activated, and the pushing component 33, driven by the driving component 31, presses the second opposite corner of the cell housing. To facilitate rapid and accurate positioning of the cell housing, two additional limiting components 2 can be provided at the two adjacent vertices of the cell positioning unit 11 adjacent to the first vertices. This arrangement ensures high positioning accuracy of the cell housing, preventing inaccurate cell positioning due to misalignment and ensuring the quality of cell production.

[0046] In some embodiments, such as Figure 1 , 3 As shown, in order to make the performance of the push angle mechanism 3 more stable, sliding components 34 are also provided on both sides of the drive component 31, including a slide rail 341 and a slider 342 that slides relative to the slide rail 341. The slide rail 341 is arranged in the same direction as the drive component 31, and the push plate 32 is disposed on the slider 342.

[0047] In some embodiments, such as Figure 1 , 3 As shown, the end of the push plate 32 is also provided with a buffer assembly 35, including a stop 351 and a buffer 352. The stop 351 is provided at the end of the push plate 32 and is perpendicular to the direction of the long plate 3312. The buffer 352 is provided on both sides of the stop 351.

[0048] In some embodiments, the cell positioning mechanism further includes a controller and a position sensor connected to the controller. The controller controls the start and stop of the drive assembly 31 according to the sensing signal of the position sensor to achieve automated positioning of the cell housing.

[0049] In use, the position of the limiting component 2 is adjusted according to the size of the battery cell housing so that the battery cell housing can be accurately placed in the corresponding position. Then, the position of the clamp 332 is adjusted by the second fixing plate 3311 and the long plate 3312 so that the clamp of the pushing component 33 can push the second opposite corner of the battery cell housing tightly. Then, the start and stop of the drive component 31 is controlled by the controller to realize the synchronous automatic positioning of multiple battery cell housings.

[0050] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
