The battery module boxing clamp comprises a clamp body, an adsorption component and two lifting and clamping mechanisms. The adsorption component is arranged at the bottom of the clamp body, and the two lifting and clamping mechanisms are respectively arranged on the two sides of the clamp body in a lifting manner. The battery module boxing clamp is configured to: in the process of carrying, the adsorption component adsorbs the battery module, and the lifting and clamping mechanisms are lowered and clamped on the two sides of the battery module to jointly fix the battery module; in the process of boxing, the lifting and clamping mechanisms are loosened and lifted to avoid the battery module, and the battery module is only kept in the adsorption state by the adsorption component.

When boxing, the lifting and clamping mechanisms are lifted to avoid the battery module, and the battery module is only fixed by the adsorption component adsorbing the top of the battery module, so that the traditional side clamping mechanism can be prevented from being hindered in the process of unfolding in the gap narrow box due to the thickness problem.

Description

Technical Field

[0001] This application relates to the field of automated assembly technology for battery modules, and in particular to a battery module loading gripper and a battery module loading device. Background Technology

[0002] In automated battery module assembly, traditional grippers typically employ side and end clamping mechanisms. To ensure accurate placement of the battery module, the gripper tip must enter the gap between the battery module and the side wall of the housing along with the battery module. When the battery module is in place and the gripper releases its gripper inside the housing, it needs to extend laterally outwards. However, with the increasing energy density of battery systems, the design gap between the battery module and the housing is becoming increasingly smaller. Under such conditions of excessively small gaps, traditional side and end clamping mechanisms often suffer from thickness limitations, causing their extension path to be blocked by the inner wall of the housing, resulting in the gripper becoming stuck and unable to exit smoothly, thus failing to meet customer requirements. Utility Model Content

[0003] In view of the shortcomings of the prior art, this application provides a battery module loading gripper and a battery module loading device that can smoothly exit the box.

[0004] To solve the above-mentioned technical problems, in a first aspect, this application discloses a battery module box clamp, including a clamp body, an adsorption component and two lifting clamping mechanisms. The adsorption component is disposed at the bottom of the clamp body, and the two lifting clamping mechanisms are respectively disposed on both sides of the clamp body in a lifting manner.

[0005] The battery module loading gripper is configured as follows:

[0006] During transport, the adsorption component adsorbs the battery module, and the lifting clamping mechanism descends and clamps both sides of the battery module to jointly fix the battery module.

[0007] When the battery module is placed in the box, the lifting clamping mechanism releases and rises to avoid it, and the battery module is held in an adsorption state only by the adsorption component.

[0008] As an optional implementation, in the embodiment of the first aspect of this application, the lifting clamping mechanism includes a lifting drive, a first mounting plate, a clamping drive, and a clamping assembly. The fixed end of the lifting drive is disposed on the gripper body, the first mounting plate is connected to the movable end of the lifting drive, the fixed end of the clamping drive is connected to the first mounting plate, and the clamping assembly is connected to the movable end of the clamping drive. The lifting drive is used to drive the clamping assembly to rise or fall, and the clamping drive is used to drive the clamping assembly to clamp or release the battery module.

[0009] As an optional implementation, in an embodiment of the first aspect of this application, the driving force of the clamping drive member of one of the lifting clamping mechanisms is greater than the driving force of the clamping drive member of the other lifting clamping mechanism.

[0010] As an optional implementation, in an embodiment of the first aspect of this application, the clamping assembly includes a second mounting plate and a clamping side plate. The second mounting plate is connected to the movable end of the clamping drive member, and the clamping side plate is disposed on the second mounting plate for clamping or releasing the battery module.

[0011] As an optional implementation, in an embodiment of the first aspect of this application, the clamping assembly further includes a bottom support, which is disposed at the bottom of the clamping side plate and is used to support the battery module.

[0012] As an optional implementation, in an embodiment of the first aspect of this application, the gripper body is provided with a first slide rail, and the first mounting plate is provided with a first slider that slides in cooperation with the first slide rail.

[0013] As an optional implementation, in an embodiment of the first aspect of this application, the first mounting plate is provided with a second slide rail, and the clamping assembly is provided with a second slider that slides in cooperation with the second slide rail.

[0014] As an optional implementation, in the embodiment of the first aspect of this application, the battery module loading gripper further includes a positioning member, which is disposed at the bottom of one end of the gripper body and can be used to position the end of the battery module.

[0015] As an optional implementation, in the embodiment of the first aspect of this application, the adsorption component is a sponge suction cup.

[0016] Secondly, this application discloses a battery module loading device, including a base, a robotic arm, and a battery module loading gripper as described above. The robotic arm is fixed to the base, and the battery module loading gripper is disposed on the robotic arm.

[0017] This application provides a battery module loading gripper and a battery module loading device. The battery module loading gripper includes a gripper body, an adsorption component, and two lifting clamping mechanisms. The battery module loading gripper is configured such that: during transport, the adsorption component adsorbs the battery module, and the lifting clamping mechanisms descend and clamp both sides of the battery module to jointly fix the battery module. The lowering and clamping mechanisms during transport can resist transport disturbances and work together with the adsorption component to better fix the battery module to the gripper, thereby stably transporting the battery module; during loading, the lifting clamping mechanisms release and rise to avoid the battery module, and the battery module is only held in an adsorption state by the adsorption component, that is, only the adsorption component adsorbed on the top of the battery module drives the battery module to extend into the box. This avoids the traditional side clamping mechanism being obstructed in the narrow gap of the box due to thickness issues, thus enabling the gripper to smoothly enter and exit the box even when the gap between the battery module and the box is too small.

[0025] Please refer to the following: Figures 1 to 3 This embodiment discloses a battery module loading device, including a base 200, a robotic arm 300, and a battery module loading gripper 100. The robotic arm 300 is fixed to the base 200, and the battery module loading gripper 100 is disposed on the robotic arm 300. The battery module loading device in this solution is used to realize the handling and loading of battery modules, that is, the battery module loading gripper is used for the handling and loading of battery modules. The battery module loading gripper 100 of this solution includes a gripper body 10, an adsorption component 20, and two lifting clamping mechanisms. The adsorption component 20 is located at the bottom of the gripper body 10, and the two lifting clamping mechanisms are respectively and movably located on both sides of the gripper body 10. The battery module loading gripper 100 and its battery module loading device are configured such that: during handling, the adsorption component 20 adsorbs the battery module, and the lifting clamping mechanisms descend and clamp both sides of the battery module to jointly fix the battery module; during loading, the lifting clamping mechanisms release and rise to avoid the battery module, and the battery module is held in an adsorption state only by the adsorption component 20. With this design, when it is necessary to handle and load the battery module, the lifting clamping mechanisms descend and clamp during handling to resist handling disturbances, and work together with the adsorption component 20 to better fix the battery module to the gripper, thereby stably handling the battery module. When entering the box, the device rises to avoid obstruction, and is fixed only by adsorbing the top of the battery module through the adsorption component 20, and also by pulling the battery module into the box. This avoids the traditional side clamping mechanism from being obstructed in the narrow gap of the box due to thickness issues, thus enabling the clamps to smoothly enter and exit the box even when the gap between the battery module and the box is too small.

[0026] In some embodiments, the lifting and clamping mechanism includes a lifting drive component 31, a first mounting plate 32, a clamping drive component 33, and a clamping assembly 34. The fixed end of the lifting drive component 31 is located on the gripper body 10. The first mounting plate 32 is connected to the movable end of the lifting drive component 31. The fixed end of the clamping drive component 33 is connected to the first mounting plate 32. The clamping assembly 34 is connected to the movable end of the clamping drive component 33. The lifting drive component 31 is used to drive the clamping assembly 34 to rise or fall, and the clamping drive component 33 is used to drive the clamping assembly 34 to clamp or release the battery module. With this design, the lifting drive component 31 realizes the lifting action of the clamping assembly 34, and the clamping drive component 33 realizes the clamping action. The two-stage drive has a clear division of labor, and the actions are coordinated and reliable.

[0027] It is understood that in other embodiments, linkage mechanisms, cam mechanisms, or lead screw drives may be used instead of the design of lifting drive 31 and clamping drive 33, and these are not limited here.

[0028] Furthermore, to avoid the risk of battery module crushing due to tolerance or alignment errors, the driving force of the clamping drive 33 of one lifting clamping mechanism is greater than that of the clamping drive 33 of the other lifting clamping mechanism. With this design, the larger driving force on one side serves as a positioning reference, while the smaller driving force on the other side provides flexible clamping. The two work together to adapt to the dimensional tolerances of the battery module, preventing damage to the battery casing due to excessive internal forces generated by the two sides pressing against each other.

[0029] It is understood that in other embodiments, the same driving force, adjustable driving force, or graded driving force can be used instead of different driving forces, and this is not limited here.

[0030] In some embodiments, the clamping assembly 34 includes a second mounting plate 341 and a clamping side plate 342. The second mounting plate 341 is connected to the movable end of the clamping drive member 33, and the clamping side plate 342 is disposed on the second mounting plate 341 for clamping or releasing the battery module. With this design, the second mounting plate 341 transmits the clamping driving force, and the clamping side plate 342 directly contacts the battery module to achieve clamping, resulting in a simple structure and stable clamping.

[0031] It is understood that in other embodiments, grippers, clamping blocks, or flexible fixtures may be used instead of the design of clamping side plate 342, and this is not limited here.

[0032] Furthermore, the clamping assembly 34 also includes a base 343, which is located at the bottom of the clamping side plate 342 and is used to support the battery module. With this design, the base 343 provides bottom support while the clamping side plate 342 clamps the battery module, preventing the battery module from slipping during transportation and improving safety.

[0033] It is understood that in other embodiments, a tray, bracket, or vacuum adsorption may be used instead of the bottom support 343 design, and this is not limited here.

[0034] In some embodiments, the gripper body 10 is provided with a first slide rail 11, and the first mounting plate 32 is provided with a first slider 322 that slides in cooperation with the first slide rail 11. With this design, the first slide rail 11 and the first slider 322 cooperate to provide guidance for the first mounting plate 32, ensuring that the lifting and clamping mechanism lifts smoothly and positions accurately.

[0035] It is understood that in other embodiments, guide posts, guide sleeves, linear bearings, or slides may be used instead of the design of the first slide rail 11 and the first slider 322, and this is not limited here.

[0036] In addition, the first mounting plate 32 is provided with a second slide rail 321, and the clamping assembly 34 is provided with a second slider 3411 that slides in cooperation with the second slide rail 321. With this design, the second slide rail 321 and the second slider 3411 cooperate to provide guidance for the clamping assembly 34, ensuring smooth and stable clamping action and improving clamping accuracy.

[0037] It is understood that in other embodiments, guide rails, slide bars, or rollers may be used instead of the design of the second slide rail 321 and the second slider 3411, and this is not limited here.

[0038] In some embodiments, the battery module loading gripper 100 further includes a positioning element 40, which is located at the bottom of one end of the gripper body 10 and can be used to position the end of the battery module. With this design, the positioning element 40 contacts the end of the battery module when the gripper descends to pick up the material, achieving initial positioning and ensuring that the adsorption component 20 accurately adsorbs the battery module, thereby improving the material picking accuracy.

[0039] It is understood that in other embodiments, positioning pins, positioning blocks, or visual positioning may be used instead of the positioning element 40, and this is not limited here.

[0040] In this embodiment, the adsorption component 20 is a sponge suction cup. This design allows the sponge suction cup to have good flexibility and sealing properties, adapting to uneven battery module surfaces, providing stable adsorption force, and avoiding damage to the battery module surface.

[0041] It is understood that in other embodiments, vacuum suction cups, magnetic suction cups, or adhesive pads may be used instead of sponge suction cups, and this is not limited to these designs.

[0042] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and concept of this application, and all such substitutions or changes should fall within the protection scope of the appended claims.
