Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a module gripping device. Background Technology

[0002] During the production process, battery modules need to be transferred between different processes. They also need to be transferred when assembling battery modules into battery packs or when mounting them onto vehicles. Since battery modules consist of several individual battery cells and structural components, they are quite heavy, and lifting equipment is typically used to lift and transfer them.

[0003] However, existing lifting fixtures are all connected to the battery modules via several hooks. If the connection structures of different battery modules are different or the battery module sizes are different, it is necessary to replace them with hooks that can match them, and to adjust the position of the hooks so that the hook spacing matches the size of the battery modules. The existing lifting fixtures have poor adaptability.

[0004] Therefore, there is an urgent need to design a module gripping device to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0042] This embodiment provides a module gripping device that can adapt to the transfer of modules of different sizes, eliminating the need for frequent hook replacements and saving horizontal space occupied by the module gripping device. Figures 1-3As shown, the module gripping device includes a bearing assembly 10, a driving component 60, a transmission assembly 20, and at least two gripper assemblies 30. The gripper assemblies 30 are divided into two groups and are spaced apart. The bearing assembly 10 is used to connect with the lifting tool and includes a bearing plate 11. The driving component 60 is disposed on one side of the bearing plate 11, and the gripper assemblies 30 are disposed on the other side of the bearing plate 30. The transmission assembly 20 passes through the bearing plate 11 and connects between the driving component 60 and the gripper assemblies 30. The driving component 60 drives at least two gripper assemblies 30 to move closer or further apart from each other through the transmission assembly 20.

[0043] The aforementioned module gripping device uses a drive component 60 to drive a transmission assembly 20, which in turn causes the gripper assemblies 30 to move closer together. The gripper assemblies 30 open and close to grip the module, making it compatible with modules of different sizes and widths. It eliminates the need to change the clamps, making it easy to operate. Furthermore, by connecting the gripping assembly to a lifting tool, the module can be transferred.

[0044] In addition, the drive unit 60 and the gripper assembly 30 are arranged on both sides of the support plate 11, which can save space in the horizontal direction of the gripping device, making the gripping device structure more compact, convenient for gripping, and easier to move.

[0045] In addition, the bottom of the gripper assembly 30 can support the battery and provide upward support to the battery, which helps to prevent the battery from slipping off the gripper assembly 30 and ensures the stability of the module transportation.

[0046] Optionally, in this embodiment, the driving member 60 includes a linear driving member 61 and a first rack 62. The first rack 62 is mounted on the output end of the linear driving member 61, and the linear driving member 61 can drive the first rack 62 to move in a preset direction.

[0047] Optionally, the transmission assembly 20 includes a first gear 23, a connecting shaft 24, and two second racks 26. The linear drive 61 is mounted on the support plate 11. The connecting shaft 24 passes through the support plate 11 and is rotatably connected to the support plate 11. The first gear 23 is coaxially connected to both ends of the connecting shaft 24. The axial direction of the connecting shaft 24 extends in the vertical direction (Z direction in the figure), and the vertical direction is perpendicular to the preset direction. The first gear 23 meshes with the first rack 62. The two second racks 26 are parallel to the support plate 11 and mesh with the second gear 25. The two sets of gripper assemblies 30 are connected to the two second racks 26 one by one. It is understood that the two second racks 26 extend along the first direction and mesh with the second gear 25 respectively; in the first direction (X direction in the figure, X direction is perpendicular to Z direction, in this embodiment, X direction is consistent with the preset direction, in other embodiments, X direction and preset direction can also be set at an angle, which is not limited here), the two gripper assemblies 30 are slidably engaged with the support plate 11, the gripper assembly 30 and the second rack 26 are arranged one-to-one, and each gripper assembly 30 is connected to a second rack 26.

[0048] The module gripping device described above drives the first rack 62 to move in a preset direction via the linear drive 61. The first gear 23 is driven to rotate due to its meshing with the first rack 62, which in turn drives the connecting shaft 24 and the second gear 25 to rotate synchronously. Since the two second racks 26 mesh with the second gear 25 respectively, the two second racks 26 are driven to move in opposite directions along the first direction, which in turn drives the gripper assembly 30 to move closer or further away from each other. Thus, the bearing assembly 10 can be continuously connected to the lifting tool. After the gripper assembly 30 clamps the module, the lifting tool can transfer the module without the need for frequent hook replacement, making the operation simple.

[0049] Optionally, in this embodiment, the linear drive 61 is a cylinder. In other embodiments, the linear drive 61 can also be a linear motor, etc., which is not limited here.

[0050] In other embodiments, the drive element 60 may also be a drive element that directly outputs rotational motion, with a transmission gear fixedly connected to its output end. The transmission gear meshes with the first gear 23; this is not limited here. Optionally, as... Figure 1 As shown, a limiting component 50 is installed on the support plate 11. The limiting component 50 serves to limit the extreme position of the first rack 62. At the same time, a sensor is installed on it. If the first rack 62 contacts it, the output end of the linear drive component 61 stops moving to prevent the module from being clamped too tightly.

[0051] Optionally, such as Figure 2As shown, the gripper assembly 30 includes a connector 31 and grippers 33. A corresponding second rack 26 is connected to the connector 31, and the connector 31 is slidably engaged with the support plate 11. The gripper 33 includes a first horizontal portion 331, a first vertical portion 332, and a second horizontal portion 333. The first horizontal portion 331 is connected to the connector 31, and the first vertical portion 332 is connected between the first horizontal portion 331 and the second horizontal portion 333. The second horizontal portion 333 supports the bottom of the module. The second horizontal portion 333 supports the bottom of the module when gripping it, preventing the module from sliding vertically due to its own weight during transfer, thus preventing the module from falling off. In other words, when the two gripper assemblies 30 clamp the module, the second horizontal portion 333 provides support, allowing the gripping force of the grippers 33 to be relatively small while ensuring stable module transfer. It is understandable that if the second horizontal part 333 is not provided, the vertical friction force formed by the clamping force of the two first vertical parts 332 will balance the weight of the module. This requires a large clamping force, which is difficult for the linear drive 61 to achieve and may cause the module to fall during the transfer process.

[0052] Optionally, such as Figure 2 As shown, a waist-shaped hole 3311 extending along the length direction of the second rack 26 is provided on the first horizontal part 331, and the locking member passes through the waist-shaped hole 3311 to connect with the connecting member 31. With the above arrangement, the position of the gripper 33 can be adjusted in the first direction, further expanding the length range of the module that the two grippers 33 can adapt to.

[0053] Optionally, such as Figure 2 As shown, a buffer 34 is provided on the inner side of the second horizontal part 333. The buffer 34 has a certain elasticity and can protect the module. In addition, the buffer 34 can also increase the friction between the gripper 33 and the battery module, preventing the module from slipping off the gripper 33.

[0054] Optionally, such as Figure 1 and Figure 2 As shown, the module gripping device also includes a buffer gripper 40, which includes a sliding rod 41, a pressure head 42, and an elastic element 43. The sliding rod 41 slides vertically against the support plate 11, and the top of the sliding rod 41 is limited to the support assembly 10. The pressure head 42 is connected to the bottom of the sliding rod 41. The elastic element 43 is sleeved on the outside of the sliding rod 41, and both ends of the elastic element 43 abut against the support assembly 10 and the pressure head 42, respectively. With the above configuration, after the module is gripped, the pressure head 42 presses on the module, and under the action of the elastic element 43, the pressure head 42 presses the module against the second horizontal part 333, preventing the battery module and the first gripper 33 from displacing relative to each other in the horizontal direction. Together with the gripper assembly 30, the pressure head 42 limits the position of the module, further improving the stability of the battery module gripping.

[0055] Optionally, such as Figure 1 As shown, the bearing assembly 10 also includes a sleeve 12, which passes through the bearing plate 11. The top of the slide rod 41 is limited by the sleeve 12, and one end of the elastic element 43 abuts against the sleeve 12. It can be understood that the sleeve 12 has a relatively long vertical length, which provides a larger contact area when sliding with the slide rod 41, thereby ensuring the stability of the slide rod 41 and preventing it from tilting in the vertical direction.

[0056] In this embodiment, four buffer claws 40 and four sleeves 12 are provided, respectively located at the four feet of the support plate 11, to ensure the balance of pressure on the module.

[0057] Optionally, such as Figure 1 As shown, the slide rod 41 includes a connected rod portion 411 and a limiting portion 412. The rod portion 411 is slidably engaged with the sleeve 12, and the diameter of the limiting portion 412 is larger than the diameter of the rod portion 411. At least one of the pressure head 42 and the limiting portion 412 is detachably connected to the slide rod 41. This configuration ensures that the slide rod 41 can be inserted into the sleeve 12 from one end without interference. Furthermore, when the pressure head 42 is detachably connected to the slide rod 41, it can be easily replaced if it wears out after prolonged use.

[0058] Optionally, such as Figure 1 As shown, the supporting assembly 10 also includes a lifting component 13 and at least two lifting rings 14. The lifting component 13 and the supporting plate 11 are aligned at their centers, and the axis of the connecting shaft 24 is on the same straight line as the center of the supporting plate 11. The lifting rings 14 are symmetrically arranged on the lifting component 13 with the center of the lifting component 13 as the center of symmetry. Specifically, the lifting component 13 and the supporting plate 11 are connected by four connecting rods 15. With the above arrangement, the lifting tool can be directly connected to the lifting rings 14 for a long time without replacing other parts, which is simple to operate and ensures the force balance of the module gripping device and the stability of the module during transportation.

[0059] Optionally, such as Figure 1 As shown, four lifting rings 14 are provided, and the four lifting rings 14 are respectively located at the four corners of the lifting component 13. This ensures that the lifting component 13 is subjected to uniform force after the entire device is lifted, and prevents the module from tilting when it is transferred.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
