Description

Technical Field

[0001] This disclosure generally relates to the field of workpiece positioning technology. More specifically, this disclosure relates to a positioning fixture for battery cell mounting. Background Technology

[0002] In existing processes such as the production of pouch batteries, workpiece positioning mechanisms are used to align and fix the position of the workpieces to be processed (such as cells and batteries) relative to the actuators of the processing or testing equipment. Common cell positioning mechanisms include fixtures with rigid positioning mechanisms, which use positioning pins and holes to form shape or size fits with the edges or other structural features of the target cell to determine its position. However, fixed positioning components cannot adapt to changes in the specifications and models of the cells being processed. When a cell needs to be changed, the corresponding positioning mechanism must be replaced simultaneously, leading to increased production debugging time and reduced efficiency.

[0003] In view of this, there is an urgent need to provide a positioning fixture for battery cell placement in order to reduce the adjustment time when positioning various battery cells. Utility Model Content

[0004] In order to at least address one or more of the technical problems mentioned above, this disclosure proposes a positioning fixture for battery cell setup in several aspects.

[0005] This disclosure provides a positioning fixture for setting up battery cells, comprising: a locking assembly including a plurality of abutting members and a plurality of limiting portions, wherein the abutting members are movably disposed on the limiting portions, and at least two abutting members move relative to each other along a first direction to abut the battery cell; a locking drive assembly including a plurality of locking drive mechanisms disposed facing each other, wherein the locking drive mechanisms are drivably connected to the abutting members; and an unlocking drive assembly including an abutting member movable relative to the abutting members, wherein the abutting member abuts against the abutting members along the moving direction of the abutting members, and the first direction is parallel to the horizontal plane.

[0006] In some embodiments, the locking assembly further includes three abutting members, namely a first abutting member, a second abutting member, and a third abutting member. The first abutting member and the second abutting member move relative to each other along a first direction to abut the battery cell, and the third abutting member moves along a second direction to abut the battery cell. The second direction is parallel to the horizontal plane and perpendicular to the first direction.

[0007] In some embodiments, the unlocking drive assembly includes a linear drive member, and the abutment member is driven by the linear drive member to move along a third direction. The abutment member includes an inclined top surface that is inclined relative to the third direction and can abut against a first abutment member, a second abutment member, and a third abutment member, respectively. The third direction is perpendicular to the horizontal plane.

[0008] In some embodiments, the linear drive member is arranged along a third direction, the inclined top surface is a conical surface, and the first abutting member, the second abutting member, and the third abutting member are arranged on the circumferential outer side of the abutting member.

[0009] In some embodiments, the first abutting member, the second abutting member, and the third abutting member are further provided with follower wheels protruding toward one side of the inclined top surface, and the follower wheels abut against the inclined top surface.

[0010] In some embodiments, the positioning fixture further includes a fixed frame, and the locking component, locking drive component and unlocking drive component are all disposed on the fixed frame. The locking drive mechanism includes a telescopic member, one end of which is fixedly connected to the abutment member and the other end of which is fixedly connected to the fixed frame.

[0011] In some embodiments, an adjustment platform is also included, which includes an adjustment frame for carrying the battery cell and an adjustment mechanism fixedly connected to the fixed frame. The adjustment mechanism includes an adjustment part that can move in a third direction, the adjustment part abutting against the adjustment frame in a second direction, and the third direction being perpendicular to the horizontal plane.

[0012] In some embodiments, the fixing frame includes a fixing plate, the adjusting frame includes an adjusting plate, the fixing plate and the adjusting plate are arranged parallel to each other along a third direction, the side of the adjusting plate opposite to the fixing plate is used to carry the battery cell, and the abutting member includes an abutting surface, which is located or partially located on the side of the adjusting plate opposite to the fixing plate, so as to limit the abutment of the battery cell.

[0013] In some embodiments, the fixing plate is provided with a drive through hole, the abutment is aligned with the drive through hole and can extend at least partially from the drive through hole in a third direction, and a plurality of abutment members are disposed in the circumferential direction of the drive through hole.

[0014] In some embodiments, the limiting part includes a fixed part and a movable part that are slidably disposed. The fixed part is fixedly disposed on the fixing frame, and the movable part is movable relative to the fixed part in a first direction or a second direction. A plurality of abutting members are respectively fixedly disposed on a movable part.

Furthermore, in some embodiments, by using an unlocking drive assembly with an inclined top surface, multiple abutment members can be pushed and moved simultaneously by the movement of one abutment member. Even further, in some embodiments, by providing conical abutment members, the contact area between the abutment members and each abutment member can be reduced, thus reducing friction.

Detailed Implementation

[0025] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, not all of them. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0026] It should be understood that the terms “comprising” and “including” used in this disclosure and claims indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0027] It should also be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of this disclosure. As used in this disclosure and claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this disclosure and claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes such combinations.

[0028] As used in this specification and claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrase "if determined" or "if [described condition or event] is detected" may be interpreted, depending on the context, as "once determined," "in response to determination," "once [described condition or event] is detected," or "in response to detection of [described condition or event]."

[0029] In existing processes such as the production of pouch batteries, it is necessary to ensure that the position of the target workpiece is aligned with the corresponding processing and inspection equipment during each inspection and processing step. The workpiece to be processed or inspected must be limited to prevent displacement or tilting during transfer between processes or during processing or inspection. Therefore, a workpiece positioning mechanism is required to align and fix the position of the workpiece to be processed (e.g., battery cells, etc.) relative to the actuator of the processing or inspection equipment. Common cell positioning mechanisms include fixtures with rigid positioning mechanisms such as positioning pins and positioning holes. These mechanisms use positioning pins and holes to form shape or size fits with the edge or other structural features of the target battery cell to determine its position. However, because such cell positioning mechanisms use fixed positioning parts that abut against the battery cell, when the specifications of the battery cell to be processed change, the corresponding positioning mechanism needs to be replaced simultaneously, leading to increased production costs and reduced efficiency. Furthermore, during battery cell installation, it is necessary to ensure that the positioning component and the battery cell are strictly aligned. Under such circumstances, whether the alignment operation is carried out manually or with the help of conveying equipment, there will be difficulties in aligning the battery cell and the positioning component. Improper placement can easily cause the battery cell to tilt, which will have an adverse impact on production efficiency.

[0030] In view of this, the present disclosure provides a positioning fixture for battery cell setup, which, by setting a first and a second abutment that can move relative to each other, and a locking drive assembly and an unlocking drive assembly that drive the first and second abutment to move closer or further apart to lock or unlock the battery cell, can achieve automatic alignment and positioning of battery cells of various specifications, thereby improving production efficiency.

[0031] The specific embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. In this embodiment, for ease of description, the following will be used... Figure 1 The plane parallel to the cell shown is defined as a horizontal plane. One width direction of the cell is defined as a first direction, the length direction perpendicular to the width direction is defined as a second direction, and the direction perpendicular to the horizontal plane is defined as a third direction. The positions and orientations of other related mechanisms and components in this disclosure are described based on this. The above orientation descriptions are merely illustrative and do not constitute a limitation on the actual installation positions and orientations of the components in this disclosure.

[0032] Figure 1 An exemplary perspective view of a positioning fixture for battery cell setup, representing some embodiments of this disclosure, is shown. Figure 1 In the illustrated embodiment, the positioning fixture for battery cell placement includes an adjustment platform 10, a locking component 20, an unlocking drive component 30, and a locking drive component 40. The adjustment platform 10 includes an adjustment frame 11 for placing and supporting the battery cell 90, and an adjustment mechanism 12 for adjusting the position of the adjustment frame 11. The locking component 20 includes multiple abutments and multiple limiting portions 24. The abutments are movably disposed on the limiting portions 24, and at least two abutments move relative to each other along a first direction to abut the battery cell 90, wherein the first direction is parallel to the horizontal plane. Specifically, in this embodiment, the multiple abutments include a first abutment 21 and a second abutment 22 that are movable relative to the limiting portions 24, and may further include a third abutment 23. The unlocking drive component 30 and the locking drive component 40 are both driven and connected to the first abutment 21, the second abutment 22, and the third abutment 23. The locking drive component 40 is used to drive the first abutment 21, the second abutment 22, and the third abutment 23 to abut against the battery cell 90, respectively. The unlocking drive component 30 is used to drive the first abutment 21, the second abutment 22, and the third abutment 23 to disengage from the battery cell 90, respectively.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, Figure 2 An exemplary cross-sectional view of a positioning fixture for battery cell placement, according to some embodiments of this disclosure, is shown. Figure 3 An exemplary exploded view of a positioning fixture for battery cell placement according to some embodiments of this disclosure is shown. In this embodiment, the positioning fixture for battery cell placement includes a fixed frame 50, an adjusting frame 11 connected to one side of the fixed frame 50, which includes an adjusting plate 111 for carrying the battery cell, and the fixed frame 50 includes a fixed base 52 and a fixed plate 51, the fixed plate 51 being fixedly disposed on the upper side of the fixed base 52. The fixed plate 51 is parallel to the adjusting plate 111 and is spaced apart from the adjusting plate 111 along a third direction. The aforementioned plurality of limiting portions 24 are fixedly disposed on the upper side of the fixed plate 51, the limiting portion 24 including a fixed portion 242 and a movable portion 241 capable of moving relative to the fixed portion 242. In this embodiment, the limiting portion 24 is a guide rail assembly, the fixed portion 242 is a guide rail fixedly disposed on the fixed plate 51, and the movable portion 241 is a slider slidably disposed on the guide rail.

[0034] Three limiting portions 24 are provided corresponding to the first abutment 21, the second abutment 22, and the third abutment 23. The guide rails of the two limiting portions 24 corresponding to the first abutment 21 and the second abutment 22 are collinear, allowing the first abutment 21 and the second abutment 22 to approach or move away from each other along the guide rail assembly. The guide rail corresponding to the third abutment 23 is set perpendicular to the moving direction of the first abutment 21 and the second abutment 22, allowing the third abutment 23 to abut against the battery cell 90 in this perpendicular direction.

[0035] The first abutting member 21 includes a first fixing block 211, a first support member 212, and a first abutting block 213, which are fixedly connected from bottom to top. The first fixing block 211 is fixedly connected to the moving part 241 of the limiting part 24, and its bottom is relatively limited relative to the moving part 241 through size and shape matching. The first support member 212 is generally L-shaped, comprising a bottom plate and a side vertical plate perpendicular to each other. The bottom surface of the bottom plate of the first support member 212 is fixedly connected to the first fixing block 211, while the side vertical plate of the first support member 212 extends vertically upward at the end of the bottom plate away from the first fixing block 211, protruding from the upper surface of the adjusting plate 111 on one side. The first abutting block 213 is fixedly disposed at the top of the side vertical plate and abuts against the battery cell 90. The first abutment block 213 is generally elongated, so that a longer first abutment surface 213a can be provided on its side facing the battery cell 90, increasing its contact area with the battery cell 90 and achieving more stable positioning. Thus, the lower side of the first abutment member 21 is guided and limited by the limiting part 24, so that the first abutment block 213 on its upper side can move along the direction defined by the limiting part 24 and abut against the battery cell 90.

[0036] Similar to the first abutment 21, the second abutment 22 includes a second fixing block 221, a second support member 222, and a second abutment block 223, which are fixedly connected from bottom to top. The third abutment 23 includes a third fixing block 231, a third support member 232, and a third abutment block 233. The second abutment block 223 and the third abutment block 233 respectively have a second abutment surface 223a and a third abutment surface 233a for abutting the battery cell 90. The connection structure of each component of the second abutment 22 and the third abutment 23 is basically similar to that of the first abutment 21. The difference is that the second abutment block 223 of the second abutment 22 is provided with a transverse adjustment groove 2231 extending along the moving direction of the second abutment 22, and the third abutment block 233 of the third abutment 23 is provided with a longitudinal adjustment groove 2331 extending along the moving direction of the third abutment 23. The second abutment block 223 is fixedly connected to the upper end of the second support member 222 by bolts passing through the transverse adjustment groove 2231, and the third abutment block 233 is fixedly connected to the upper end of the third support member 232 by bolts passing through the longitudinal adjustment groove 2331. Thus, the transverse adjustment groove 2231 is used to adjust the relative distance between the second abutment surface 223a and the first abutment surface 213a of the second abutment block 223, while the longitudinal adjustment groove 2331 is used to adjust the distance between the third abutment surface 233a and the battery cell 90. This allows the positioning fixture used for battery cell placement to adapt to the dimensions of battery cells 90 of different specifications and to be adjusted according to actual production needs, improving positioning accuracy.

[0037] In addition, see Figures 4a-4b The second support member 222 is a split structure, comprising a vertical support plate 2221 arranged in a third direction and a horizontal fixing plate 2222 arranged in a horizontal direction. The vertical support plate 2221 also has a vertical adjustment elongated hole 222a penetrating its surface. The vertical support plate 2221 is fixedly connected to the horizontal fixing plate 2222 by bolts passing through the vertical adjustment elongated hole 222a. With the help of the vertical adjustment elongated hole 222a, the vertical support plate 2221 can further adjust its height longitudinally to adjust the relative height between the second abutment block 223 and the first abutment block 213, to accommodate different cell 90 shapes. Those skilled in the art will understand that in some embodiments not shown, the first support member 212 and the third support member 232 are also configured as split structures with corresponding vertical adjustment elongated holes to further increase their compatibility with various specifications of cell 90.

[0038] See Figure 4a and Figure 4b , Figure 4aAn exemplary perspective view of a positioning fixture for battery cell setup according to some embodiments of this disclosure is shown, wherein the adjustment platform 10 and the first abutment block 213, the second abutment block 223, and the third abutment block 233 have been removed for clarity of its construction. Figure 4b Then it shows Figure 4a A partially enlarged schematic diagram of part A. In this embodiment, the locking drive assembly 40 includes multiple locking drive mechanisms 41. Each locking drive mechanism 41 includes a telescopic member, one end of which is fixedly connected to a stop member, and the other end is fixedly connected to the fixing frame 50, providing a continuous force to the fixing block for resetting it. In this embodiment, the telescopic member includes a spring fixing pin 412 fixedly disposed on the fixing plate 51 and a spring 411. One end of the spring 411 is connected to the spring fixing pin 412, and the other end is correspondingly connected to one of the first fixing block 211, the second fixing block 221, and the third fixing block 231. The extension direction of the spring 411 is consistent with the movement direction of its corresponding stop member, and pulls its corresponding stop member toward the center of the fixing plate 51. Therefore, when locking the battery cell, the first abutment 21, the second abutment 22 and the third abutment 23 can automatically press against the battery cell 90 with the help of the spring tension to correct the position of the battery cell 90 on the adjustment plate 111 and align it with the processing or handling equipment.

[0039] Those skilled in the art will understand that while an embodiment using a linear spring 411 and a spring retaining pin 412 as a telescopic member has been described above, this disclosure is not limiting in this respect. For example, in some embodiments not shown, the telescopic member includes a pneumatic spring or a single-acting cylinder to provide a stable and continuous reset force.

[0040] Furthermore, in some embodiments not shown, only the first abutment 21 and the second abutment 22 are provided, and a longitudinal positioning block is provided on the first abutment 21 or the second abutment 22. When setting the battery cell 90, the longitudinal positioning block serves as a reference, and the alignment adjustment of the battery cell 90 is only performed in the lateral direction (i.e., the direction in which the first abutment 21 and the second abutment 22 move relative to each other). This simplifies the equipment structure and reduces production and maintenance costs. Alternatively, in some embodiments not shown, an additional fourth abutment is provided, which is positioned opposite to the third abutment 23 to abut and limit the battery cell 90 relative to the third abutment 23, further enhancing the accuracy of the battery cell 90's positioning. As another example, the first abutment 21, the second abutment 22, and the third abutment 23 are an integral structure, with their fixing block, support member, and abutment block formed integrally, further enhancing the structural strength of the abutment.

[0041] See you again Figure 2 and Figure 3The unlocking drive assembly 30 includes a linear drive member 31 and an abutment member 32 that is driven to move by the linear drive member 31. The abutment member 32 includes an inclined top surface 32a that is inclined relative to its moving direction, and the inclined top surface 32a abuts against the first abutment member 21, the second abutment member 22, and the third abutment member 23. In this embodiment, the linear drive member 31 is a cylinder arranged in a third direction, with its cylinder body fixedly mounted on the fixing frame 50, and its cylinder rod fixedly connected to the abutment member 32. The lower end of the abutment member 32 is fixedly connected to the cylinder rod, and its vertical upper end is provided with a conical inclined top surface 32a for abutting against the multiple abutment members. The center portion of the fixing plate 51 is provided with a drive through hole 51a that extends in a third direction, and the vertical upper end of the abutment member 32 can at least partially protrude upward through the drive through hole 51a. The first fixing block 211, the second fixing block 221 and the third fixing block 231 of the multiple abutting members are respectively arranged on the circumferential outer side of the drive through hole 51a, and each of the three members is provided with a follower wheel 25 protruding towards the center along its respective moving direction on the side facing the drive through hole 51a, so that the first abutting member 21, the second abutting member 22 and the third abutting member 23 abut against the inclined top surface 32a by means of their respective follower wheels 25.

[0042] Therefore, when the abutment 32 is driven by the linear drive 31 to move upward in a third direction, the inclined top surface 32a abuts against and pushes the corresponding follower wheels 25 of the first abutment 21, the second abutment 22, and the third abutment 23. While rolling along the inclined top surface 32a, the corresponding follower wheels 25 push the first abutment 21, the second abutment 22, and the third abutment 23 to move outward along the corresponding limiting part 24, thereby realizing the synchronous release of the abutment members in the three directions to the battery cell 90. The first fixing block 211 and the second fixing block 221 are symmetrically arranged with the abutment 32 as the center along their moving direction. Similarly, the third fixing block 231 is arranged rotationally symmetrically with the first fixing block 211 and the second fixing block 221 with the abutment 32 as the center.

[0043] When the battery cell 90 is released, the cylinder rod driving the linear drive 31 extends. Since each abutment is set at the same distance and angle relative to the conical inclined top surface 32a, the extended inclined top surface 32a drives the abutments in each direction to simultaneously and synchronously disengage from the battery cell 90. Thus, after the positioning fixture for battery cell placement unlocks relative to the battery cell 90, the battery cell 90 remains in its original positioning state, eliminating the need for realigning the battery cell 90 during subsequent handling or other processes, thereby improving production efficiency. Furthermore, since the fixing blocks of the first abutment 21 and the second abutment 22 are symmetrically arranged relative to the abutment 32, the forces exerted by the two abutments on the abutment 32 are opposite in direction and equal in magnitude, thus at least partially canceling each other out, reducing the lateral force on the abutment 32 and lowering the risk of jamming due to the abutment 32's misalignment. Furthermore, setting the inclined top surface 32a to a conical shape reduces the contact area between the abutting member 32 and each abutting member, thereby reducing friction and lowering the probability of jamming due to friction. Also, since the conical inclined top surface 32a maintains a consistent inclination in any direction, it prevents rotation during driving, thus avoiding inconsistent driving forces in different directions.

[0044] Furthermore, those skilled in the art will understand that although the above describes a scheme using a cylinder arranged along a third direction as a linear drive member 31, with a cone-shaped abutment member 32 pushing against multiple abutment members, this disclosure does not limit the specific form and arrangement of the linear drive member 31 and the abutment member 32. For example, in some embodiments not shown, the linear drive member 31 is arranged in a direction inclined relative to the third direction or in a horizontal direction, while the inclined top surface 32a of the abutment member 32 is also set as a pyramidal surface, an arc surface, or multiple inclined surfaces with different inclination angles, as long as it satisfies that each abutment member abuts against the inclined top surface 32a of the abutment member 32, and can be driven by the abutment member 32 to move and unlock the battery cell 90 when the abutment member 32 moves. In some embodiments not shown, the first fixing block 211, the second fixing block 221, and the third fixing block 231 are not provided with follower wheels 25, but are provided with smooth arc surfaces or other structures that directly abut against the inclined top surface 32a, thereby simplifying the structure of the abutment member and reducing production costs.

[0045] See also Figure 1 and Figure 5 , Figure 5An exemplary perspective view of a positioning fixture for battery cell placement according to some embodiments of this disclosure is shown. In this embodiment, the adjustment frame 11 further includes an adjustment support plate 112 that is perpendicularly disposed and fixedly connected to the adjustment plate 111. The adjustment platform 10 further includes an adjustment mechanism 12, which includes an adjustment base plate 121 fixedly connected to the side of the fixing frame 50, and an adjustment boss 122, an adjustment bolt 123, and an adjustment guide assembly 125 disposed on the adjustment base plate 121. The adjustment mechanism 12 also includes an adjustment portion 124 disposed at the end of the adjustment bolt 123 and used to abut against the bottom side of the adjustment support plate 112. The side of the adjustment plate 111 facing away from the fixing plate 51 is used to support the battery cell 90. The aforementioned plurality of abutting members include corresponding plurality of abutting surfaces, each abutting surface being located or partially located on the side of the adjustment plate 111 facing away from the fixing plate 51, so as to abut and limit the battery cell 90.

[0046] One side of the adjustment base plate 121 is fixedly connected to the side of the fixing frame 50, and the other side is fixedly connected to the adjustment boss 122. The adjustment bolt 123 is threadedly connected to the adjustment boss 122 in a third direction, so that it can be rotated and raised in a third direction. The adjustment guide assembly 125 includes a guide rail arranged in a third direction and a slider arranged on the guide rail. The guide rail is fixedly connected to the adjustment base plate 121, and the slider is fixedly connected to the adjustment support plate 112, so that the adjustment frame 11 can move relative to the fixing frame 50 in a third direction. The adjustment part 124 is fixedly connected to the end of the adjustment bolt 123 to abut against the bottom end of the adjustment frame 11 in a third direction, thereby adjusting the height of the adjustment plate 111 relative to each abutment member. The positioning clamp used for battery cell installation can align and limit various battery cells 90 with different thicknesses.

[0047] According to the embodiments disclosed herein, the positioning fixture for battery cell placement is provided with a first abutting member and a second abutting member that can move relative to each other along the limiting portion, and a locking drive component and an unlocking drive component. The first abutting member and the second abutting member are driven to approach each other to abut and clamp the battery cell from both sides, or to move away from each other to disengage from the battery cell. This enables automatic alignment, positioning, and release of battery cells of various specifications, thereby reducing production adjustment time when dealing with battery cells of different specifications and improving production efficiency.

[0048] While numerous embodiments of this disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only.
