Description

Technical Field

[0001] This disclosure relates to a clamping device, and more particularly to a clamping device for transferring battery modules. Background Technology

[0002] In the automotive industry, see Figure 1 Battery modules M are typically formed by clamping multiple parallel, series-connected cells 1 between two aluminum plates, with adjacent cells 1 bonded together by strong adhesive. During operation, due to improper handling or misalignment of the assembly equipment, one or more misaligned cells 2 may appear in the battery module, either in the height or / or width direction, rendering the entire module unusable. To reuse the unusable modules, the misaligned cells are usually removed using fishing line, requiring the entire battery module M to be transferred from the assembly station to a service bench for disassembly. However, battery modules M are quite heavy, weighing at least several tens of kilograms, typically requiring two workers to lift them. Because the bonding between adjacent cells is not strong enough, the module may break at some point during lifting, preventing its successful transfer to the service bench. Furthermore, if workers accidentally touch the positive and negative terminals of a cell with metal objects during lifting, causing a short circuit, there is a risk of explosion.

[0003] Therefore, it is desirable to design a clamping and lifting device for transferring battery modules, so as to transfer battery modules to the desired location in a simple, safe and reliable manner without the need for manual lifting. Summary of the Invention

[0004] This disclosure aims to provide a clamping device for transferring battery modules to avoid the aforementioned drawbacks of the prior art.

[0005] This disclosure provides a clamping and lifting device for transferring battery modules. The clamping and lifting device includes: a support frame used in operation to align positioning pins on a tray for assembling battery modules, the battery modules including multiple battery cells; a lifting assembly securely mounted on the support frame, the lifting assembly having multiple lifting lugs for lifting by a lifting device; a clamping device mounted above the lifting assembly, including a first clamping component and a slidably adjustable second clamping component; and a spacing adjustment device disposed on the clamping device. The spacing adjustment device is used to adjust the distance between the first and second clamping components to suit either securely clamping the battery module or fully releasing the battery module. Thus, using the clamping and lifting device according to this disclosure, battery modules can be transferred to a desired location in a simple, safe, and reliable manner without the need for manual lifting.

[0006] In one example, the first and second clamping assemblies each include: a horizontal top plate, a vertical arm fixed to the top plate, a connecting arm orthogonally connected to the vertical arm, and a plurality of grippers attached to the connecting arm. Each gripper includes a gripping contact made of a flexible material. Preferably, each gripper is attached to the connecting arm by a screw fitted with a spring component. Thus, the clamping device according to this disclosure can provide an adjustable and appropriate clamping force for clamping the battery module, preventing electrolyte leakage from the battery cell due to excessive clamping force, and preventing the battery cell from separating or even falling off due to insufficient clamping force.

[0007] In one example, each clamp is used to simultaneously hold at least two cells in the battery module along its length. This prevents adjacent battery packs from separating due to insufficient adhesive strength.

[0008] In one example, each clamp further includes: a limiting connector threaded to a screw, a pivot shaft, and a clamping contact connector, the pivot shaft extending through the limiting connector and the clamping contact connector, such that the clamping contact can pivot about the pivot shaft by a pivot angle. Thus, the pivoting rotation of the clamping contact facilitates providing an adjustable clamping force for misaligned cells.

[0009] In one example, the pivot angle is adjusted by a spring component, and the extreme range of the pivot angle is defined by two side limiting plates of the limiting connector. This provides not only adjustable clamping force but also prevents excessive oscillation of the clamping contacts.

[0010] In one example, an auxiliary support extending laterally inward is provided at the lower end of the vertical arm of the second clamping assembly to provide auxiliary support at the bottom of the battery module. Thus, if the battery module tilts downward due to insufficient clamping force, the auxiliary support provides auxiliary support from the bottom of the battery module to prevent it from falling.

[0011] In one example, the extension amount of the auxiliary support is adjusted by operating an adjustment handle. Thus, by adjusting the extension amount of the auxiliary support, adequate support can be provided while preventing interference with other operations.

[0012] In one example, the support frame includes four legs, with a positioning guide on at least one leg. The positioning guide guides the support frame to align with a positioning pin disposed on a tray, providing initial positioning of the clamping device. Thus, the initial positioning of the clamping device determines the predetermined positioning of the first clamping assembly of the clamping device relative to a first side of the battery module.

[0013] In one example, the spacing adjustment device includes a hand-cranked wheel positioned outside a connecting plate between the two vertical arms of the second clamping assembly, for driving the second clamping assembly to move back and forth relative to a trapezoidal screw positioned above the lifting assembly. Thus, the rotation of the hand-cranked wheel is simple and safe, and the trapezoidal screw ensures smooth movement of the second clamping assembly when the hand-cranked wheel is rotating, while preventing movement of the second clamping assembly when the hand-cranked wheel is not rotating.

[0014] In one example, the spacing adjustment device includes a limiting member fixedly mounted on the top plate of the first clamping assembly and a locking member pivotally mounted on the top plate of the second clamping assembly. The locking member is capable of being in a first locking configuration and a second disengaged configuration relative to the limiting member. In the first locking configuration, a first distance between the clamping contacts of the first and second clamping assemblies is sufficient to ensure that the clamping contacts securely clamp the battery module. In the second disengaged configuration, a second distance between the clamping contacts of the first and second clamping assemblies is greater than the width of the battery module to release the clamping of the battery module. Thus, the spacing adjustment device provides appropriate clamping force for lifting and transfer operations when the clamping contacts are clamping, and releases the clamping contacts when they are not clamping, preventing unintentional contact with the battery module.

[0015] In one example, the locking member is rod-shaped and pivotally connected to a support on the top plate of the second clamping assembly. The front end of the locking member has a hook, and the rear end contacts a spring on the support. In another example, the limiting member is ramp-shaped, corresponding to the hook of the locking member for engagement. In yet another example, the locking member is connected to a roller via a roller arm at a predetermined distance from the front end. A protrusion is provided on a support fixed to the top plate of the first clamping assembly, the shape of which is adapted to provide a smooth reciprocating rolling path for the roller. Thus, the construction of the locking and limiting members provides a reliable and smooth engagement.

[0016] In one example, a thrust return spring is positioned between the first end of the lifting assembly and the connecting plate between the two vertical arms of the first clamping assembly, for pushing the first clamping assembly to reset. This achieves the reset of the first clamping assembly in a simple manner.

[0017] In one example, the lifting device includes: a first limiting structure installed at a position corresponding to the vertical arm of the first clamping assembly at a first end of the lifting assembly; a second limiting structure installed at the center portion of the second end of the lifting assembly; and a third limiting structure installed on the side of the second end of the top plate of the first clamping assembly. Thus, the setting of each limiting structure ensures operational safety. Attached Figure Description

[0032] Exemplary embodiments will now be described in detail. In the following description, when referring to the accompanying drawings, unless otherwise stated, the same reference numerals in different drawings denote the same or similar elements. The drawings are not necessarily drawn to scale and are intended for illustrative purposes. The following exemplary embodiments are intended for description only and are not intended to limit the scope of this disclosure.

[0033] Reference Figure 1-3 Battery module M is typically assembled as follows: a first aluminum plate, intended for placement at the first end of battery module M, is placed on a tray 6 for assembly, with the positioning holes of the first aluminum plate aligned with positioning pins on the tray 6. Multiple battery cells 1 are then placed side-by-side sequentially and bonded together with strong adhesive. Finally, a second aluminum plate is assembled at the second end to complete the assembly of battery module M. However, during operation, due to improper operation or misalignment of the assembly equipment, one or more misaligned battery cells 2 may appear in the battery module that are not precisely positioned in the height and / or width directions (see...). Figure 2 This results in the entire battery module becoming scrap. To reuse the scrap, the battery module M needs to be transported from the assembly station to the repair station via a transfer vehicle 4 for dismantling. Therefore, this disclosure provides a clamping device 10 for transferring battery modules, to move the battery module M, transported to the vicinity of the repair station via the transfer vehicle 4, to the repair station.

[0034] Reference Figure 4-5 The diagram shows a perspective view of a clamping and lifting device 10 for transferring a battery module according to the present disclosure. The clamping and lifting device 10 includes a support frame 7, a lifting assembly 8, a clamping device, and a spacing adjustment device 30. The lifting assembly 8 is securely mounted on the support frame 7 and has a plurality of lifting lugs 11 for lifting by a lifting device (not shown). The plurality of lifting lugs includes four lugs. The clamping device is mounted above the lifting assembly and includes a first clamping assembly 15 and a slidably adjustable second clamping assembly 17. The support frame 7 includes four legs, at least one of which has a positioning guide 9 for guiding the support frame 7 to align with a positioning pin provided on a tray 6 to provide initial positioning of the clamping and lifting device 10, thereby determining a predetermined position of the first clamping assembly 15 relative to a first side of the battery module M. The spacing adjustment device 30 is mounted on the clamping device for adjusting the distance between the first clamping assembly 15 and the second clamping assembly 17 to suit either securely clamping the battery module or fully releasing the battery module. During operation, the first clamping assembly 15 only makes fine adjustments under the action of the spacing adjustment device 30, while the second clamping assembly 17 can slide back and forth along the lead screw within the desired adjustment range to adjust the distance between the first clamping assembly 15 and the second clamping assembly 17 as needed.

[0035] See Figure 5-7 The first clamping assembly 15 and the second clamping assembly 17 each include: a horizontal top plate, a vertical arm fixed to the top plate, a connecting arm 26 orthogonally connected to the vertical arm, and a plurality of grippers 20 attached to the connecting arm. Each gripper is attached to the connecting arm 26 by a screw 28 fitted with a spring member 24. The plurality of grippers 20 may be connected to the connecting arm 26 at equal intervals to provide appropriate clamping force at multiple locations. The screw 28 may include four fastening screws. See also Figure 8 The spring component is a disc spring 24 sleeved on the screw, and a sleeve (not shown) can be sleeved around the disc spring on the screw 28 for easy replacement of the sleeve after wear. Alternatively, the sleeve can be a wear-resistant sleeve made of a wear-resistant material.

[0036] Each clamp 20 includes a clamping contact 21 made of flexible material at its head for simultaneously clamping at least two cells in the battery module along its length, preventing adjacent cells from separating due to insufficient adhesion. Since the cells are filled with electrolyte, the clamping contacts are typically made of flexible material to prevent electrolyte leakage due to excessive clamping force. This provides sufficient friction to firmly clamp the battery module M without damaging the cell casing. Examples of flexible materials include polyurethane.

[0037] refer to Figure 7-8 Each clamp 20 also includes a limiting connector 25 threaded to a screw 28, a pivot shaft 22, and a clamping contact connector 27. The pivot shaft 22 extends through the limiting connector 22 and the clamping contact connector 27, allowing the clamping contact 21 to pivot about the pivot shaft 22 by a pivot angle. The magnitude of this pivot angle can be adjusted by the elastic force of the spring component 24 according to the actual clamping situation of the clamping contact 21, so as to provide appropriate clamping force even for misaligned cells that are not accurately positioned relative to the standard assembly position in the length direction of the battery module. For example, if the misaligned cell 2 protrudes outward relative to the standard assembly position, the corresponding clamping contact will be retracted outward by the elastic force of the spring component 24, so as to provide appropriate clamping force for the protruding cell and avoid electrolyte leakage in the cell due to excessive clamping force. If the misaligned cell 2 is recessed inward relative to its standard assembly position, the corresponding clamping contact will pivot appropriately around the pivot axis 22 under the elastic force of the spring component and extend inward to provide appropriate clamping force for the recessed cell, thereby preventing separation or even falling off due to insufficient clamping force. (Reference) Figure 7 The limiting connector 25 includes two side limiting plates 23, each of which can be a sheet metal baffle to prevent excessive swinging of the clamping contact. Thus, the limit range of the pivot angle is defined by the two side limiting plates 23 of the limiting connector 25.

[0038] Reference Figure 6 and Figure 9-10 An auxiliary support member 40 extending laterally inward is provided at the lower end of the vertical arm of the second clamping assembly 17 to provide auxiliary support at the bottom of the battery module M. When the clamping force is insufficient to clamp the battery module M, the battery module M is prone to tilting downward relative to the vertical arm of the second clamping assembly 17. Therefore, the auxiliary support member 40 is provided to provide support at the bottom of the battery module M to prevent it from falling. The auxiliary support member 40 includes an adjusting handle 18, a connecting rod, and contacts made of flexible material attached to the connecting rod. The length of the contacts is comparable to the length of the battery module M to provide sufficient auxiliary support along the entire length of the battery module when needed. The flexible material of the contacts of the auxiliary support member 40 can be the same as the flexible material of the clamping contacts. During operation, the extension of the contacts of the auxiliary support member 40 can be greater than the extension of the clamping contacts (see...). Figure 9 The extension amount can be adjusted by operating the adjusting handle 18. The adjusting handle 18 can be a push-pull handle.

[0039] See Figure 5 and Figure 9-10 The spacing adjustment device 30 includes a hand-cranked wheel 12, which is located on the outer side of the connecting plate between the two vertical arms of the second clamping assembly 17. The hand-cranked wheel drives the movement of the second clamping assembly relative to a lead screw 19 positioned above the lifting assembly 8, thereby providing movement operation for the second clamping assembly. The lead screw 19 is preferably a trapezoidal lead screw to ensure smooth movement of the second clamping assembly 17 when the hand-cranked wheel 12 rotates, and to prevent movement of the second clamping assembly 17 when the hand-cranked wheel 12 is not rotating.

[0040] See Figure 9-10 The spacing adjustment device 30 also includes a limiting member 36 fixedly mounted on the top plate of the first clamping assembly 15 and a locking member 32 pivotally mounted on the top plate of the second clamping assembly 17. The locking member 32 is capable of being in a first locking configuration relative to the limiting member 36 (see...). Figure 9 ) and the second separation structure (see Figure 10 In the first locking configuration, the first distance between the clamping contacts of the first clamping assembly 15 and the second clamping contact of the second clamping assembly 17 is sufficient to ensure that the clamping contact 21 firmly clamps the battery module M. In the second disengagement configuration, the second distance between the clamping contacts of the first clamping assembly 15 and the second clamping contact of the second clamping assembly 17 is greater than the width of the battery module M to release the clamping of the battery module. Using the spacing adjustment device 30, the clamping contacts provide appropriate clamping force for lifting and transfer operations during clamping, and release the clamping contacts when not clamping to avoid unintentional contact with the battery module.

[0041] The locking member 32 is rod-shaped and pivotally connected to a support on the top plate of the second clamping assembly 17. The front end of the locking member has a hook portion 33, and the rear end contacts a spring 34 placed on the support. The limiting member 36 is ramp-shaped, corresponding to the shape of the hook portion 33, to achieve locking. The locking member is connected to the roller 38 via a roller support arm at a predetermined distance from the front end. A protrusion 39 is provided on a support fixed to the top plate of the first clamping assembly 15. The shape of the protrusion 39 is adapted to provide a smooth back-and-forth rolling path for the roller 38 (see...). Figure 11-12 When the locking component 32 is not engaged with the limiting component 36, the spring 34 is in a naturally extended state. As the roller 38 rises along the arc shape of the protrusion 39, the front end of the locking component also rises and crosses the ramp. At this time, the spring 34 is compressed due to the lowering of the rear end of the locking component. When the roller 38 continues to descend along the arc path past the highest point of the protrusion 39, the hook portion 33 also descends past the highest point of the ramp and smoothly engages with the vertical end of the ramp of the limiting component 36 by means of the elastic force of the spring 34. At this time, the spring 34 has returned to its naturally extended state. Thus, the spring 34 ensures smooth engagement and avoids noise. The release process of the engagement and lock is performed by reversing the operation.

[0042] See Figure 5 and Figure 9-10 The thrust return spring 42 is disposed between the first end of the lifting assembly and the connecting plate between the two vertical arms of the first clamping assembly, and is used to push the first clamping assembly to return to its original position. Figure 5 As shown, the thrust return spring 42 is mounted on a spring seat located at the middle position of the upper surface of the first end of the lifting assembly 8. When the clamping device is not performing a clamping operation, the thrust return spring 42 is in a naturally extended state.

[0043] See Figure 13 The lifting device further includes: a first limiting structure 52 installed at a position corresponding to the vertical arm of the first clamping assembly 15 at the first end of the lifting assembly 8 to limit the outward limit of the first clamping assembly 15; a second limiting structure 54 installed at the center portion of the second end of the lifting assembly 8 to limit the outward limit of the second clamping assembly 17; and a third limiting structure 56 installed on the side of the second end of the top plate of the first clamping assembly 15 to limit the inward limit of the second clamping assembly 17. The provision of each limiting structure helps prevent excessive movement of the relevant components. See also Figure 5On the upper surface of the lifting assembly 8, indicator components 14 and 13 are also installed to indicate the amount of movement of the second clamping assembly 17. These are used to indicate lifting from the storage compartment and lifting into the storage compartment, respectively, so that the operator can intuitively feel whether the second clamping assembly 17 has reached the battery module clamping position for lifting or has reached the battery module release position for lifting. The battery module clamping position is set according to the clamping force requirements on both sides of the battery cell. Pressure sensor patches are attached to both sides of the battery cell. The second clamping assembly 17 moves to the battery module clamping position to clamp the battery module, but does not exceed the clamping force requirements on both sides of the battery module. The pressure sensor is used for detection to avoid deformation of the battery cell due to excessive clamping force. Optionally, a display component can be provided on the top plate of the second clamping assembly to display the magnitude of the clamping force measured by the pressure sensor.

[0044] The operation of the clamping device 10 according to this disclosure is described below. After the battery module M is transported to the vicinity of the maintenance platform via the transfer vehicle 4, the clamping device is lifted above the battery module M placed on the tray 6 using a lifting device, so that the positioning guide 9 on the support frame leg is aligned with the positioning pin provided on the tray 6 to provide a pre-position of the first clamping assembly 15 of the clamping device relative to one side of the battery module M. At this time, the first clamping assembly 15 and the second clamping assembly 17 are in the pre-positioned position and the initial safe position, respectively, and their clamping contacts are not in contact with the battery module M. Next, the hand-cranked wheel 12 is rotated so that the second clamping assembly 17 moves along the trapezoidal screw 19 toward the first clamping assembly 15 until the hook portion 33 of the locking member 32 engages and locks with the limiting member 36 under the smooth rolling of the roller 38 along the protrusion 39. At this time, the clamping contacts of the clamping device of the second clamping assembly 17 have contacted and clamped the battery module M. Then, the hand-cranked wheel 12 is rotated in the reverse direction to retract the second clamping assembly 17 by a certain distance. At this time, since the locking component 32 and the limiting component 36 are engaged and locked, this retraction movement also pulls the first clamping assembly 15 to move together and compresses the thrust return spring 42. This retraction distance can be indicated by the indicating component 14. At this time, the first clamping assembly 15 and the second clamping assembly 17 have completed clamping the battery module M, and then the lifting device transfers the battery module M to the desired position on the maintenance table. Optionally, the magnitude of this retraction distance is suitable for the clamping contacts of the first clamping assembly 15 and the second clamping assembly 17 to move to contact and clamp the battery module M. At this time, the measured value of the pressure sensor provided at the clamping contact can be displayed on the display component for the operator to determine whether the battery module M has been clamped. If the displayed pressure is within a predetermined range, it indicates that the battery module M has been clamped, and the retraction operation stops. At this point, the first clamping assembly 15 and the second clamping assembly 17 have completed clamping the battery module M. The lifting device then transfers the battery module M to the desired position on the maintenance platform. Afterwards, a release operation is performed on the battery module M, the reverse of the clamping operation. That is, the hand-cranked wheel 12 is first rotated, causing the second clamping assembly 17 to move along the trapezoidal screw 19 towards the first clamping assembly 15 until the locking member 32 disengages from the limiting member 36. The hand-cranked wheel 12 is then rotated in the reverse direction, causing the second clamping assembly 17 to retract to its initial safe position (indicated by the indicating member 13), while the first clamping assembly 15 is reset to its predetermined position under the force of the push-return spring 42. Then, after the lifting device removes the clamping device 10, the maintenance operation on the battery module M begins.

[0045] Therefore, by using the clamping device 10 according to this disclosure, the battery module M can be transferred to the desired location in a simple, safe and reliable manner without the need for manual lifting.
