Abstract

This application relates to a battery module clamp for holding a battery module. The battery module clamp includes a base, a clamping mechanism, an adsorption mechanism, and a bottom support mechanism. The clamping mechanism includes a first clamping mechanism and a second clamping mechanism arranged along a first direction, wherein the first direction is parallel to the length direction of the battery module. The adsorption mechanism is disposed on the base and is used to adsorb onto the sidewall of the battery module along a second direction, wherein the second direction is parallel to the width direction of the battery module. The bottom support mechanism is connected to the adsorption mechanism and is used to support the battery module along a third direction, which is the height direction of the battery module. By setting the adsorption mechanism to adsorb onto the sidewall of the battery module along the second direction and by using the bottom support mechanism to support the battery module, the probability of overall deformation of the battery module is reduced, and the damage to the conductive connecting piece at the top of the battery module caused by the sagging of the battery module is reduced.

Description

Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to a battery module fixture. Background Technology

[0002] In the new energy lithium battery industry, batteries are mainly divided into power batteries and energy storage batteries. The production processes for these two types of batteries are largely similar: lithium battery raw materials are processed into battery cells, these cells are assembled into battery modules, and then the battery modules are assembled into a PACK box to ultimately produce a lithium battery pack. The transfer of the welded battery modules to the PACK box is a crucial step in the production process. The battery modules are transferred to the PACK box by clamping both ends with fixtures, mounting them on an automated robot or semi-automatic overhead crane, and then moving them into the PACK box. Four to eight battery modules are placed in consecutively until the PACK box is full.

[0003] With the development of the industry and market demand, the length of battery modules has been gradually increasing, and there are now ultra-long battery modules with a length of up to 2000mm. Due to the excessive length of the battery modules, if the original traditional battery module clamping and handling technology is used, the clamping force at both ends of the clamp is insufficient to squeeze and clamp the battery cells in the middle of the battery module during the clamping and handling process. The battery cells will sag due to their own weight, causing the overall shape of the battery module to deform, and will also damage the welding effect of the conductive connecting piece (also known as busbar, connecting strip or bar) on the top of the battery module. Utility Model Content

[0004] Based on this, a battery module fixture is provided to address the problem of transporting battery modules assembled from individual battery cells.

[0005] A battery module clamp for holding a battery module, the battery module clamp comprising:

[0006] Base;

[0007] The clamping mechanism disposed on the base includes a first clamping mechanism and a second clamping mechanism arranged along a first direction, wherein the first direction is parallel to the length direction of the battery module;

[0008] An adsorption mechanism is provided on the base, which is used to adsorb onto the sidewall of the battery module along a second direction, wherein the second direction is parallel to the width direction of the battery module.

[0009] A bottom support mechanism is connected to the adsorption mechanism. The bottom support mechanism is used to support the battery module along a third direction, which is the height direction of the battery module.

[0010] In one embodiment, the adsorption mechanism is slidably engaged with the base, and the adsorption mechanism is capable of sliding along the second direction to move closer to or further away from the battery module.

[0013] Adsorption power source;

[0014] A suction cup is disposed on the mounting plate and is connected to the output end of the adsorption power source. The suction cup is located on the side of the mounting plate close to the battery module along the second direction.

[0015] In one embodiment, the adsorption mechanism further includes a sponge disposed on the suction cup, the sponge having through holes communicating with the suction cup, the sponge being used to adhere to the battery module.

[0016] In one embodiment, the adsorption mechanism further includes a limiting block disposed on the mounting plate, the limiting block being disposed on the side of the mounting plate along the third direction near the base.

[0017] In one embodiment, the backstop mechanism includes:

[0018] A first telescopic cylinder is provided on the adsorption mechanism;

[0019] The second telescopic cylinder is connected to the output end of the first telescopic cylinder;

[0020] A bottom plate is connected to the output end of the second telescopic cylinder. The first telescopic cylinder can drive the second telescopic cylinder and the bottom plate to move along a third direction. The second telescopic cylinder can drive the bottom plate to move along a second direction, wherein the third direction is parallel to the height direction of the battery module.

[0021] In one embodiment, the second telescopic cylinder and the bottom plate are slidably connected by a second guide rail structure, wherein the length direction of the second guide rail of the second guide rail structure is parallel to the second direction.

[0022] In one embodiment, a limiting mechanism connected to the base is further included. The limiting mechanism includes a limiting drive and a limiting stop connected to the output end of the limiting drive. The limiting drive can drive the limiting stop to move so that the limiting stop is located on the side of the battery module away from the adsorption mechanism along the second direction.

[0023] In one embodiment, the limiting drive includes a third telescopic cylinder and a fourth telescopic cylinder. The output end of the third telescopic cylinder is connected to the fourth telescopic cylinder, and the output end of the fourth telescopic cylinder is connected to the limiting stop. The third telescopic cylinder can drive the fourth telescopic cylinder and the limiting stop to move along the second direction, and the fourth telescopic cylinder can drive the limiting stop to move along the third direction.

[0024] In one embodiment, the first clamping mechanism includes a first clamping cylinder and a first clamping block connected to the output end of the first clamping cylinder;

[0025] The second clamping mechanism includes a second clamping cylinder and a second clamping block connected to the output end of the second clamping cylinder;

[0026] The first clamping cylinder is configured to drive the first clamping block to move closer to or further away from the second clamping block along the first direction; the second clamping cylinder is configured to drive the second clamping block to move closer to or further away from the first clamping block along the first direction.

[0027] The driving force generated by the first clamping cylinder is greater than the driving force generated by the second clamping cylinder.

[0028] The aforementioned battery module clamp, by arranging the first clamping mechanism and the second clamping mechanism along a first direction and cooperating with each other, clamps the battery module along the first direction (i.e., the length direction of the battery module). An adsorption mechanism is provided to adhere to the sidewall of the battery module along the second direction, providing adsorption force to reduce the sagging of the battery module due to gravity. Furthermore, a bottom-supporting mechanism supports the bottom wall of the battery module, further reducing sagging due to gravity, lowering the probability of overall deformation of the battery module, and reducing the likelihood of damage to the conductive connecting pieces at the top of the battery module caused by sagging.

[0029] The battery module clamp of this application uses an adsorption mechanism to adsorb onto the side wall of the battery module along the second direction, and uses a bottom support mechanism to lift the battery module, thereby solving the problem of battery cells sagging and battery module deformation during the transportation of ultra-long battery modules.

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] In the new energy lithium battery industry, batteries are mainly divided into power batteries and energy storage batteries. The production processes for these two types of batteries are largely similar. Both involve producing battery cells (710) from lithium battery raw materials, assembling the 710 battery cells into battery modules (700), and then assembling the battery modules (700) into a PAKC box to ultimately produce a lithium battery pack. For example... Figure 1 As shown, multiple battery cells 710 are assembled to form a battery module 700, wherein the multiple battery cells 710 in the battery module 700 are arranged along a first direction.

[0052] This application provides a battery module clamp for holding a battery module 700, such as... Figures 1 to 7 As shown, the battery module fixture includes: a base 500, a clamping mechanism, an adsorption mechanism 300, and a bottom-supporting mechanism 400; the clamping mechanism is disposed on the base 500, and includes a first clamping mechanism 100 and a second clamping mechanism 200 arranged along a first direction, wherein the first direction is parallel to the length direction of the battery module 700; the adsorption mechanism 300 is disposed on the base 500, and the adsorption mechanism 300 is used to adsorb onto the sidewall of the battery module 700 along a second direction, wherein the second direction is parallel to the width direction of the battery module 700; the bottom-supporting mechanism 400 is connected to the adsorption mechanism 300, and the bottom-supporting mechanism 400 is used to support the battery module 700 along a third direction, wherein the third direction is the height direction of the battery module 700.

[0053] The aforementioned battery module clamp, by arranging the first clamping mechanism 100 and the second clamping mechanism 200 along a first direction on the base 500, with the first clamping mechanism 100 and the second clamping mechanism 200 cooperating with each other, clamps the battery module 700 along the first direction (that is, the length direction of the battery module 700). By providing an adsorption mechanism 300 to adsorb onto the sidewall of the battery module 700 along a second direction, the adsorption mechanism 300 provides adsorption force, thereby reducing the problem of the battery module 700 sagging due to gravity. Furthermore, by providing a bottom support mechanism 400 to support the bottom wall of the battery module 700, the bottom support mechanism 400 lifts the battery module 700, further reducing the problem of the battery module 700 sagging due to gravity, lowering the probability of overall deformation of the battery module 700, and reducing the possibility of damage to the conductive connecting piece at the top of the battery module 700 caused by sagging.

[0054] The battery module clamp of this application uses an adsorption mechanism 300 to adsorb onto the side wall of the battery module 700 along the second direction, and uses a bottom support mechanism 400 to support the battery module 700, thereby solving the problem of the battery cells 710 in the battery module 700 sagging and the battery module 700 deforming during the transportation of the ultra-long battery module 700.

[0055] Specifically, such as Figure 2 As shown, a mounting flange 510 is provided on the base 500, which is used to connect to the output end of an automatic robot or a semi-automatic gantry crane.

[0056] In one embodiment, such as Figure 3 As shown, the first clamping mechanism 100 includes a first clamping cylinder 110 and a first clamping block 120 connected to the output end of the first clamping cylinder 110; the second clamping mechanism 200 includes a second clamping cylinder 210 and a second clamping block 220 connected to the output end of the second clamping cylinder 210; the first clamping cylinder 110 is configured to drive the first clamping block 120 to move closer to or away from the second clamping block 220 in a first direction; the second clamping cylinder 210 is configured to drive the second clamping block 220 to move closer to or away from the first clamping block 120 in the first direction; the driving force generated by the first clamping cylinder 110 is greater than the driving force generated by the second clamping cylinder 210.

[0057] The first clamping cylinder 110 drives the first clamping block 120, and the second clamping cylinder 210 drives the second clamping block 220. The first clamping block 120 and the second clamping block 220 move towards each other, thereby clamping or releasing the battery module 700. Moreover, the driving force generated by the first clamping cylinder 110 is greater than the driving force generated by the second clamping cylinder 210, which ensures that the reference position with the first clamping block 120 is maintained each time the battery module 700 is clamped.

[0058] In this embodiment, as Figure 3 As shown, the first clamping mechanism 100 and the second clamping mechanism 200 are both disposed on the base 500 and are arranged at intervals along the first direction. When it is necessary to clamp the battery module 700, the first clamping cylinder 110 retracts, thereby driving the first clamping block 120 to move along the first direction toward the side closer to the second clamping block 220 (e.g., Figure 3 As shown, moving to the left along the first direction, the battery module 700 is pulled back to the reference plane, and the second clamping cylinder 210 retracts, thereby driving the second clamping block 220 to move along the first direction towards the side closer to the first clamping block 120 (as shown). Figure 3 (as shown) moving to the right along the first direction, thereby clamping the battery module 700 along the first direction.

[0059] In one embodiment, such as Figure 2 , Figure 4 as well as Figure 5 As shown, the adsorption mechanism 300 is slidably engaged with the base 500. The adsorption mechanism 300 can slide along the second direction to approach or move away from the battery module 700. By allowing the adsorption mechanism 300 to slide with the base 500, when the battery module 700 is not clamped, the adsorption mechanism 300 slides along the second direction away from the battery module 700, thereby creating a clearance space and preventing interference with the clamping of the battery module 700. When the first clamping mechanism 100 and the second clamping mechanism 200 clamp the battery module 700, the adsorption mechanism 300 slides along the second direction towards the side of the battery module 700, thereby adsorbing onto the sidewall of the battery module 700 along the second direction. The adsorption mechanism 300 provides adsorption force, thereby reducing the problem of the battery module 700 sagging due to gravity.

[0060] Specifically, such as Figure 2 , Figure 4 as well as Figure 5 As shown, the adsorption mechanism 300 includes: a mounting plate 310, an adsorption power source, a suction cup, and a sponge 320. The mounting plate 310 is slidably connected to the base 500 via a first guide rail structure 330. The length direction of the first guide rail of the first guide rail structure 330 is parallel to the second direction. A bottom-supporting mechanism 400 is connected to the mounting plate 310. The suction cup is disposed on the mounting plate 310 and is connected to the output end of the adsorption power source. The suction cup is located on the side of the mounting plate 310 along the second direction close to the battery module 700. The sponge 320 is disposed on the suction cup and has through holes that communicate with the suction cup. The sponge 320 is used to adhere to the battery module 700.

[0061] A sliding engagement between the adsorption mechanism 300 and the base 500 is achieved by setting a first guide rail structure 330 on the mounting plate 310. By limiting the length direction of the first guide rail structure 330 to be parallel to the second direction, the relative sliding direction of the mounting plate 310 and the base 500 is also limited. A suction cup is provided on the mounting plate 310, and a sponge 320 is placed on the suction cup, with through holes on the sponge 320 communicating with the suction cup. When adsorption is needed, the adsorption power source starts working, and outside air flows through the through holes and the suction cup in sequence, thereby creating a negative pressure area near the sponge 320, which in turn causes the sponge 320 to adhere to the sidewall of the battery module 700 along the second direction. Furthermore, the sponge 320 is characterized by high temperature resistance, softness, good resilience, strong adsorption, and wear resistance, reducing the friction between the adsorption mechanism 300 and the battery module 700 and reducing the risk of scratching the battery module 700.

[0062] Specifically, the first guide rail structure 330 includes a slidingly fitted first guide rail and a first slider. One of the first guide rail and the first slider is disposed on the mounting plate 310 and the other is disposed on the base 500. By limiting the length direction of the first guide rail of the first guide rail structure 330 to be parallel to the second direction, the relative sliding direction of the mounting plate 310 and the base 500 is limited, so that they can only slide relative to each other along the second direction.

[0063] In this embodiment, the first guide rail of the first guide rail structure 330 is disposed on the mounting plate 310, and the first slider is disposed on the base 500.

[0064] In other embodiments, the first guide rail of the first guide rail structure 330 is disposed on the base 500, and the first slider is disposed on the mounting plate 310.

[0065] Specifically, such as Figure 2 , Figure 4 as well as Figure 5 As shown, the adsorption mechanism 300 includes an adsorption drive 350 disposed on the base 500. The output end of the adsorption drive 350 is connected to the mounting plate 310. The adsorption drive 350 drives the mounting plate 310 to move in the second direction, thereby driving the suction cup and sponge 320 to move in the second direction.

[0066] Specifically, such as Figure 2 , Figure 4 as well as Figure 5 As shown, the adsorption mechanism 300 also includes a limiting block 340 disposed on the mounting plate 310. The limiting block 340 is disposed on the side of the mounting plate 310 near the base 500 along a third direction. By providing the limiting block 340 on the mounting plate 310, the limiting block 340 limits the movement of the battery module 700 along a third direction, preventing the battery module 700 from abutting against the lower surface of the base 500.

[0067] Specifically, the limiting block 340 is located below the base 500. When the battery module 700 is clamped, the limiting block 340 is located between the battery module 700 and the base 500.

[0068] Specifically, such as Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the battery module 700 includes multiple battery cells 710, and the adsorption mechanism 300 includes multiple mounting plates 310 arranged at intervals along a first direction. Each mounting plate 310 is provided with a suction cup, a sponge 320 and a limiting block 340. The number of sponges 320 is the same as the number of battery cells 710, so that each battery cell 710 in the battery module 700 can have a corresponding adsorption force.

[0069] In one embodiment, such as Figure 2 and Figure 6 As shown, the bottom-supporting mechanism 400 includes a first telescopic cylinder 410, a second telescopic cylinder 420, and a bottom-supporting plate 430. The first telescopic cylinder 410 is mounted on the adsorption mechanism 300. The second telescopic cylinder 420 is connected to the output end of the first telescopic cylinder 410. The bottom-supporting plate 430 is connected to the output end of the second telescopic cylinder 420. The first telescopic cylinder 410 can drive the second telescopic cylinder 420 and the bottom-supporting plate 430 to move along a third direction. The second telescopic cylinder 420 can drive the bottom-supporting plate 430 to move along a second direction, wherein the third direction is parallel to the height direction of the battery module 700.

[0070] The second telescopic cylinder 420 is connected to the output end of the first telescopic cylinder 410. The first telescopic cylinder 410 drives the second telescopic cylinder 420 and the bottom plate 430 to move together in a third direction. The output end of the second telescopic cylinder 420 is connected to the bottom plate 430. The second telescopic cylinder 420 drives the bottom plate 430 to move in a second direction, thereby supporting the battery module 700.

[0071] In one embodiment, such as Figure 2 and Figure 6 As shown, the second telescopic cylinder 420 and the bottom plate 430 are slidably connected by a second guide rail structure 440, the length direction of the second guide rail of the second guide rail structure 440 being parallel to the second direction. By providing the second guide rail structure 440, which includes a slidingly engaged second guide rail and a second slider, one of which is located on the second telescopic cylinder 420 and the other on the bottom plate 430, the relative sliding direction of the second telescopic cylinder 420 and the bottom plate 430 is limited by ensuring that the length direction of the second guide rail of the second guide rail structure 440 is parallel to the second direction, thus limiting their relative sliding direction to the second direction.

[0072] In this embodiment, the second guide rail of the second guide rail structure 440 is disposed on the second telescopic cylinder 420, and the second slider is disposed on the bottom plate 430.

[0073] In other embodiments, the second guide rail of the second guide rail structure 440 is disposed on the bottom plate 430, and the second slider is disposed on the second telescopic cylinder 420.

[0074] In this embodiment, as Figure 2 As shown, multiple sets of bottom-supporting mechanisms 400 are provided, and these multiple sets of bottom-supporting mechanisms 400 are arranged at intervals along the first direction. The specific number of bottom-supporting mechanisms 400 is set according to actual operational needs.

[0075] In one embodiment, such as Figure 2 and Figure 7 As shown, the battery module fixture also includes a limiting mechanism 600 connected to the base 500. The limiting mechanism 600 includes a limiting drive member 610 and a limiting stop 620 connected to the output end of the limiting drive member 610. The limiting drive member 610 can drive the limiting stop 620 to move, so that the limiting stop 620 is located on the side of the battery module 700 away from the adsorption mechanism 300 along the second direction. By setting the limiting mechanism 600, the limiting drive member 610 of the limiting mechanism 600 drives the limiting stop 620 to be located on the side of the battery module 700 away from the adsorption mechanism 300 along the second direction, thereby limiting the battery module 700 along the second direction by the limiting stop 620 of the limiting mechanism 600 and the sponge 320 of the adsorption mechanism 300.

[0076] Specifically, such as Figure 2 and Figure 7 As shown, the limiting drive 610 includes a third telescopic cylinder 611 and a fourth telescopic cylinder 612. The output end of the third telescopic cylinder 611 is connected to the fourth telescopic cylinder 612, and the output end of the fourth telescopic cylinder 612 is connected to the limiting stop 620. The third telescopic cylinder 611 can drive the fourth telescopic cylinder 612 and the limiting stop 620 to move in the second direction, and the fourth telescopic cylinder 612 can drive the limiting stop 620 to move in the third direction.

[0077] The third telescopic cylinder 611 drives the fourth telescopic cylinder 612 and the limiting stop 620 to move together along the second direction. The fourth telescopic cylinder 612 drives the limiting stop 620 to move along the third direction, so that the limiting stop 620 is located on the side of the battery module 700 away from the adsorption mechanism 300 along the second direction. The function of the limiting mechanism 600 in this application is to lower the limiting stop 620 to the side of the battery module 700 by the fourth telescopic cylinder 612, and then pull the limiting stop 620 back along the second direction by the third telescopic cylinder 611, so that the battery module 700 is close to the adsorption mechanism 300 structure, so as to better adsorb the battery cells 710 of the battery module 700, and at the same time prevent the battery module 700 from tipping over.

[0078] In this embodiment, as Figure 2 and Figure 7 As shown, the third telescopic cylinder 611 is connected to the base 500.

[0079] In this embodiment, as Figure 2 As shown, multiple sets of limit mechanisms 600 are provided, and these multiple sets of limit mechanisms 600 are arranged at intervals along the first direction. The specific number of limit mechanisms 600 is set according to actual operational needs.

[0080] In this embodiment, as Figure 2 As shown, the base 500 has a plate-like structure. The first clamping cylinder 110 of the first clamping mechanism 100 and the second clamping cylinder 210 of the second clamping mechanism 200 are both located on the upper surface of the base 500. The first clamping block 120 of the first clamping mechanism 100 and the second clamping block 220 of the second clamping mechanism 200 are located below the base 500.

[0081] The adsorption drive 350 of the adsorption mechanism 300 is located on the upper surface of the base 500. When the battery module 700 is clamped, the mounting plate 310, the limiting plate, the sponge 320 and the suction cup of the adsorption mechanism 300 are all located below the base 500.

[0082] The first telescopic cylinder 410 of the bottom-holding mechanism 400 is located on the side of the mounting plate 310 of the adsorption mechanism 300 away from the sponge 320. When clamping the battery module 700, the bottom-holding mechanism 400 is located below the base 500. The base 500, the first clamping mechanism 100, the second clamping mechanism 200, the adsorption mechanism 300 and the bottom-holding mechanism 400 form a space to accommodate the battery module 700. This space is a cuboid structure, and the cuboid structure space is connected to the outside along the second direction away from the adsorption mechanism 300, which facilitates clamping the battery module 700.

[0083] When the battery module 700 is clamped, the limiting mechanism 600 set on the base 500 moves, thereby blocking the side of the space that is connected to the outside by the limiting edge 620 of the limiting mechanism 600.

[0084] Based on the detailed explanation of the image structure above, this application includes the following transfer steps:

[0085] The first clamping cylinder 110 of the first clamping mechanism 100 retracts to its position to form a reference, and the second clamping cylinder 210 of the second clamping mechanism 200 retracts to pull the battery module 700 back to the reference surface, so that the battery module 700 can be squeezed and clamped between the first clamping mechanism 100 and the second clamping mechanism 200.

[0086] The adsorption drive 350 of the adsorption mechanism 300 retracts, causing the adsorption mechanism 300 to move along the second direction and fit against the side of the battery module 700 along the second direction to hold the battery module 700.

[0087] Multiple first telescopic cylinders 410 of multiple bottom-supporting mechanisms 400 extend to lower multiple bottom-supporting plates 430, and multiple second telescopic cylinders 420 of multiple bottom-supporting mechanisms 400 extend to move the bottom-supporting plates 430 in the second direction to support the bottom of the battery module 700 and maintain the overall shape of the battery module 700.

[0088] Multiple fourth telescopic cylinders 612 of multiple limiting mechanisms 600 extend, causing multiple limiting stops 620 to descend, and multiple third telescopic cylinders 611 to retract. The multiple limiting stops 620 limit the battery module 700 to the adsorption mechanism 300, so that the adsorption mechanism 300 can better hold the battery module 700.

[0089] After the battery module fixture completes the above actions, the battery module 700 can be moved into the PACK box. Then, the battery module fixture releases each mechanism in sequence, so that the battery module 700 is placed intact and undamaged in the preset position.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
