[0047] Figure 1This diagram illustrates the structure of the module gripping device provided in an embodiment of the present invention. Figure 1 (Top view angle); Figure 2 This diagram illustrates the structure of the module gripping device provided in an embodiment of the present invention. Figure 2 (Looking up from below). In the diagram, the X, Y, and Z directions are perpendicular to each other. (Refer to...) Figure 1 and Figure 2 This embodiment provides a module gripping device. The module gripping device includes a support base 100, a first clamping mechanism 200, and a second clamping mechanism 300.

[0048] Specifically, the first clamping mechanism 200 includes two sets of first grippers 210 disposed opposite each other on the support base 100 along the X direction. The positions of the two sets of first grippers 210 in the X direction are adjustable and they are distributed on both sides of the stacked battery cells. The second clamping mechanism 300 includes two sets of second grippers 310 disposed opposite each other along the Y direction. The second grippers 310 are height-adjustable to the support base 100 in the Z direction. The two sets of second grippers 310 are distributed on both sides of the stacked battery cells in the Y direction and can support the stacked battery cells in the Z direction.

[0049] Each group of first grippers 210 includes at least one first gripper 210. This embodiment of the application describes an example where each group of first grippers 210 includes one first gripper 210. Each group of second grippers 310 includes at least one second gripper 310. This embodiment of the application describes an example where each group of second grippers 310 includes one second gripper 310.

[0050] The two first grippers 210 and two second grippers 310 described above enable the fixing of stacked battery cells in both the X and Y directions. Since the spacing between the two first grippers 210 and the two second grippers 310 is adjustable, this module gripping device is suitable for gripping stacked battery cells of different lengths and widths. Because the second grippers 310 can also support the stacked battery cells in the Z direction, the gripping stability and reliability are further ensured. Furthermore, since the height of the second grippers 310 is adjustable in the Z direction, it can be used to clamp stacked battery cells of different thicknesses, expanding the application range and improving the versatility of this module gripping device.

[0051] More specifically, the second gripper 310 includes a support portion 311 and an abutment portion 312 connected at an angle to each other. In this embodiment, the support portion 311 and the abutment portion 312 are connected at right angles and integrally formed. The support portion 311 can support the bottom of the stacked battery cell in the Z direction, and the abutment portion 312 can abut against the side of the stacked battery cell in the Y direction. Through the above arrangement, the clamping and fixing of the stacked battery cell in two directions can be integrated on the second gripper 310 at the same time, and the structure is simplified while ensuring clamping stability.

[0052] More specifically, a second anti-slip pad 313 is provided on the clamping surface of the second gripper 310. That is, the second anti-slip pad 313 is provided on both the side of the support portion 311 facing the stacked battery cells and the side of the abutment portion 312 facing the stacked battery cells to enhance the friction between the second gripper 310 and the stacked battery cells. In this embodiment, the second anti-slip pad 313 can specifically be a rubber pad with protrusions or grooves on its surface.

[0053] Continue to refer to Figure 1 The module gripping device also includes a first drive mechanism 400. The first drive mechanism 400 is disposed on the support base 100. One of the two first grippers 210 is driveably connected to the first drive mechanism 400, and the other of the two first grippers 210 is fixedly disposed on the support base 100. That is, one of the two first grippers 210 can serve as a positioning reference when gripping stacked battery cells. First, the fixed first gripper 210 is brought against one side of the stacked battery cell in the X direction. Then, the position of the other first gripper 210 is adjusted using the first drive mechanism 400 until it grips the other side of the stacked battery cell in the X direction, thereby achieving reliable and stable gripping of the stacked battery cells. In this embodiment, the first drive mechanism 400 can specifically be a cylinder or a servo motor.

[0054] Preferably, the module gripping device further includes a guiding mechanism 500. The guiding mechanism 500 is disposed on the support base 100 along the X direction, and one of the two first grippers 210 is slidably engaged with the guiding mechanism 500. In this embodiment, the guiding mechanism 500 can specifically be a guide rail, and a slider is disposed on the first gripper 210 corresponding to the guide rail, the slider and the guide rail being slidably connected to each other. By providing the guiding mechanism 500, the movement of the movable first gripper 210 can be guided, ensuring accurate gripping of the stacked battery cells.

[0055] More specifically, when the first drive mechanism 400 is a servo motor, the module gripping device also needs to be equipped with a lead screw 900. The lead screw 900 is rotatably mounted on the support base 100 via a bearing 110 mounted on the support base 100, allowing it to rotate around its own axis. The lead screw 900 is coaxially connected to the output end of the servo motor and can rotate under the drive of the servo motor. The lead screw 900 is threadedly connected to the first gripper 210, which can move along the X direction under the rotation of the lead screw 900 and the sliding limit action of the guide mechanism 500.

[0056] In other embodiments, both first grippers 210 may also be movable relative to the support 100. Correspondingly, two first drive mechanisms 400 need to be provided.

[0057] Preferably, a first anti-slip pad 211 is provided on the clamping surface of the first gripper 210. This arrangement enhances the friction between the first gripper 210 and the stacked battery cells. In this embodiment, the first anti-slip pad 211 can specifically be a rubber pad with raised dots or grooves on its surface.

[0058] Continue to refer to Figure 1 and Figure 2 The module gripping device also includes a second drive mechanism 600. The module gripping device further includes a transmission mechanism 700, which includes a first guide member 710, a first fixing frame 720, and a displacement seat 730. The second gripper 310 is tractively mounted on the displacement seat 730, and its height is adjustable in the Z direction. The first guide member 710 is arranged along the Y direction, with one end connected to the support base 100 and the other end connected to the first fixing frame 720. The displacement seat 730 is slidably mounted on the first guide member 710 along the Y direction. The second drive mechanism 600 is mounted on the first fixing frame 720, and its output end is connected to the displacement seat 730, enabling it to drive the displacement seat 730 to move along the length direction of the first guide member 710. In this embodiment, the second drive mechanism 600 can specifically be a cylinder, whose action can adjust the position of the displacement seat 730 in the Y direction, thereby adjusting the position of the second gripper 310 in the Y direction. The first guide member 710 enables the installation of the displacement seat 730 and provides guidance for the movement of the displacement seat 730 along the Y direction.

[0059] Specifically, there are multiple first guide members 710. Each first guide member 710 has a rod-like structure, and the multiple first guide members 710 are parallel to each other and spaced apart in the X direction. Through the above arrangement, the stability of the displacement seat 730 and the second gripper 310 in the Y direction can be improved.

[0060] Continue to refer to Figure 1 and Figure 2 The module gripping device also includes a third drive mechanism 800, and the transmission mechanism 700 includes a second fixing frame 740 and a second guide member 750. The second guide member 750 passes through the displacement seat 730 along the Z direction and connects between the second fixing frame 740 and the second gripper 310. The drive end of the third drive mechanism 800 is disposed on the second fixing frame 740, and the output end of the third drive mechanism 800 is connected to the displacement seat 730. The third drive mechanism 800 can achieve linkage with the second gripper 310 through the second guide member 750. When the output end of the third drive mechanism 800 extends relative to the drive end, it can raise the drive end and the second fixing frame 740 together in the Z direction with the displacement seat 730 as a reference, thereby driving the second gripper 310 to rise in the Z direction relative to the displacement seat 730. When the output end of the third drive mechanism 800 retracts relative to the drive end, the drive end and the second fixed frame 740 can descend together in the Z direction relative to the displacement seat 730, using the displacement seat 730 as a reference, thereby driving the second gripper 310 to descend in the Z direction relative to the displacement seat 730. In this embodiment, the third drive mechanism 800 may specifically be a cylinder.

[0061] Specifically, the second guide member 750 includes a fixed section and a telescopic section coaxially connected. The fixed section passes through the displacement seat 730 and is connected to the second fixed frame 740, and is fixed relative to the displacement seat 730 and the second fixed frame 740. The telescopic section is connected to the second gripper 310 and is telescopically inserted into the fixed section. When the third drive mechanism 800 drives the second gripper 310 away from the support seat 100 in the Z direction, the telescopic section extends relative to the fixed section; when the third drive mechanism 800 drives the second gripper 310 closer to the support seat 100 in the Z direction, the telescopic section retracts relative to the fixed section.

[0062] Specifically, there are multiple second guide members 750, which are parallel to each other and spaced apart in the X direction. This arrangement improves the stability of the second gripper 310's movement in the Z direction.

[0063] The module gripping device provided in this embodiment also includes a displacement driving mechanism. The carrier 100 is connected to the displacement driving mechanism and can move under the drive of the displacement driving mechanism, thereby realizing the transfer of stacked battery cells. In this embodiment, the displacement driving mechanism can be a device with multiple degrees of freedom, such as a robotic arm, as long as it can realize the movement of the carrier 100. Its specific type and structure are not limited in this embodiment.

[0064] 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
