[0040] The production of square battery modules typically relies on industrial robots for the handling of incoming and outgoing components. However, in certain specific scenarios where manual transfer of modules is necessary, the application of industrial robots becomes less suitable due to factors such as space constraints, safety considerations, the complexity and flexibility of employee operations.

[0041] Handling fixtures are typically equipped with one or more grippers. These grippers must be designed to precisely fit the shape and size of the battery module to ensure safety and stability during handling. However, under current technological conditions, when the specifications of square battery modules change, existing handling fixtures often cannot meet the new requirements, leading to a decrease in handling efficiency.

[0042] In response to the above problems, such as Figure 1 As shown, an embodiment of this application provides a lifting clamp 100, mainly used for lifting and transporting square battery modules. The lifting clamp 100 includes a sliding member, a first clamping member 130, a second clamping member 140, and an adjusting member 150.

[0043] The slider includes a slide rail 121 and two sliders 122, which are slidably mounted on the slide rail 121.

[0044] like Figure 1 and Figure 2 As shown, the lifting clamp 100 also includes a fixed base 110.

[0045] The fixed base 110 is elongated, and the slide rail 121 is located below the fixed base 110.

[0046] In one embodiment, there are two slide rails 121, which are spaced apart along the length of the fixed base 110. The range of motion of the slider 122 is limited by adjusting the length of the slide rails 121.

[0047] The first clamping member 130 is connected to a slider 122, and the second clamping member 140 is connected to another slider 122. The slider 122 drives the first clamping member 130 or the second clamping member 140 to move. When the first clamping member 130 and the second clamping member 140 approach each other, the battery module is clamped. When the first clamping member 130 and the second clamping member 140 move away from each other, the battery module is released.

[0048] The adjusting member 150 connects the first clamping member 130 and the second clamping member 140. The adjusting member 150 is used to adjust the distance between the first clamping member 130 and the second clamping member 140. In this way, when it is necessary to clamp battery modules of different sizes, the first clamping member 130 and the second clamping member 140 can fix battery modules of different specifications according to the actual size of the battery modules, thereby improving the efficiency of the lifting fixture 100 in assembling battery modules, improving the practicality of the lifting fixture 100, and reducing the cost of the lifting fixture 100.

[0049] In some embodiments, the adjusting member 150 includes a central rod 151, a rotating rod 152, a first connecting rod 153, and a second connecting rod 154.

[0050] like Figure 1As shown, the central rod 151 extends along the direction of the parallel slide rail 121, and the rotating rod 152 is set along the vertical slide rail 121. A connecting hole is provided at the center of the central rod 151, and the rotating rod 152 passes through the connecting hole so that the central rod 151 rotates around the rotating rod 152.

[0051] For example, the rotating rod 152 is I-shaped, with its bottom crossbar positioned on the side of the fixed base 110 away from the slide rail 121. The center rod 151 is positioned between the two crossbars of the rotating rod 152, and the vertical rod of the rotating rod 152 passes through the connecting hole of the center rod 151. The two crossbars restrict the degree of freedom of the center rod 151, allowing it to rotate around the vertical rod.

[0052] The first link 153 connects the first clamping member 130 and the center rod 151, and the first link 153 and the center rod 151 are hinged together. The second link 154 connects the second clamping member 140 and the center rod 151, and the second link 154 and the center rod 151 are hinged together.

[0053] like Figure 1 As shown, one end of the central rod 151 is connected to the end of the first connecting rod 153, and the other end of the central rod 151 is connected to the end of the second connecting rod 154. When the central rod 151 rotates in the direction of the vertical slide rail 121, the first clamping member 130 and the second clamping member 140 move towards each other. When the central rod 151 rotates in the direction of the parallel slide rail 121, the first clamping member 130 and the second clamping member 140 move away from each other, thereby adjusting the distance between the first clamping member 130 and the second clamping member 140 according to different specifications of battery modules.

[0054] In some embodiments, the first clamping member 130 includes a first lifting ring 131, a first gripper 133, and a first connecting portion 132.

[0055] like Figure 2 As shown, the first gripper 133 is connected to the slider 122, the first gripper 133 and the first lifting ring 131 are respectively connected to the first connecting part 132, and the first connecting rod 153 and the first connecting part 132 are rotatably connected.

[0056] In one embodiment, the first gripper 133 is generally C-shaped. The first lifting ring 131 is used to secure the lifting rope. The first connecting portion 132 is connected to the slider 122 via the first gripper 133, so that the first clamping member 130 as a whole can move with the slider 122.

[0057] In some embodiments, the first connecting portion 132 is annular, the slide rail 121 passes through the first connecting portion 132, and the first lifting ring 131 and the first gripper 133 are respectively connected to the first connecting portion 132 along the direction perpendicular to the slide rail 121.

[0058] like Figure 2As shown, the first connecting part 132 is in the shape of a circular ring or a square ring. The shape of the first connecting part 132 can be set as required. By making the first connecting part 132 into a ring shape, a mounting position is provided for the first lifting ring 131, while also reducing the overall weight of the first clamping assembly and reducing the friction between the slider 122 and the slide rail 121.

[0059] In some embodiments, the lifting clamp 100 further includes a locking member 160, which includes a swing arm 161 and a brake block 162.

[0060] The swing arm 161 is rotatably connected to the first connecting part 132, and the brake block 162 is connected to the slide rail 121. The brake block 162 is provided with a limiting groove 1621, which is used to fix the swing arm 161. Figure 2 As shown, the swing rod 161 is L-shaped. When the swing rod 161 rotates to the lateral position, part of the swing rod 161 is engaged in the limiting groove 1621. Since the brake block 162 is fixedly connected to the fixed base 110, the first clamping member 130 cannot move as a whole. The second clamping member 140 is connected to the first clamping member 130 through the adjusting member 150. When the first clamping member 130 is fixed, the positions of the adjusting member 150 and the second clamping member 140 are also fixed, achieving the purpose of locking the adjusting member 150, the first clamping member 130 and the second clamping member 140.

[0061] When the swing arm 161 is rotated to the vertical position, the top of the swing arm 161 is above the first connecting part 132, and the slider 122 can move on the slide rail 121 to achieve the purpose of releasing the adjusting member 150, the first clamping member 130 and the second clamping member 140.

[0062] In some embodiments, the first lifting rings 131 are all located on the side of the slide rail 121 away from the slider 122, facilitating the assembly of the lifting ropes. The adjusting member 150 is located on the side of the slide rail 121 away from the slider 122, preventing interference between the first clamping member 130 and the second clamping member 140 and the adjusting member 150, and allowing the first connecting rod 153, the second connecting rod 154 and the center rod 151 to have greater room for movement.

[0063] In some embodiments, the first clamping member 130 and the second clamping member 140 are symmetrically arranged.

[0064] Specifically, the second clamping member 140 includes a second lifting ring, a second gripper, and a second connecting part.

[0065] In some embodiments, the lifting clamp 100 further includes a first connector 170 and a second connector 172, which are respectively connected to the slide rail 121 and are spaced apart. Multiple slots are provided on the end caps of the battery module, and the first connector 170 and the second connector 172 engage with these slots to achieve initial positioning and clamping of the battery module.

[0066] In the manual handling of square battery modules, the crane + electric hoist + handling clamp is the most widely used mechanism. Throughout the entire production process, from loading and unloading the square battery modules from the production line to transporting them to designated locations, the combination of crane + electric hoist + handling clamp demonstrates significant advantages in terms of space utilization, safety, ease of operation for employees, and flexibility.

[0067] This application also provides a hoisting device, including the hoisting clamp 100, electric hoist, and hanging frame as described in any of the above embodiments. The electric hoist is slidably mounted on the hanging frame, and the first clamping member 130 and the second clamping member 140 are respectively connected to the electric hoist via ropes.

[0068] The working process of the hoisting device in this application is as follows:

[0069] Rotate the swing arm 161 to the vertical position and release the adjusting member 150, the first clamping member 130, and the second clamping member 140;

[0070] The first connector 170 and the second connector 172 are engaged and locked into the slot of the battery module.

[0071] The electric hoist tightens the rope, causing the first jaw 133 and the second jaw to move closer together under the action of the electric hoist, until the first jaw 133 and the second jaw clamp the battery module.

[0072] During the process of the first clamp 133 and the second clamp clamping the battery module, for example, when the first clamp 133 is connected to the battery module but the second clamp is not connected to the battery module, the electric hoist moves horizontally towards the first clamp 133, so that the second clamp is connected to the battery module. It also allows the lifting clamp 100 to automatically and flexibly adjust itself to keep its center of gravity on the same straight line as the battery module, so as to clamp and transfer the battery cell module more smoothly and safely.

[0073] The electric hoist continues to tighten the rope, so that the battery module is lifted and transported. During the transport process, the first jaw 133 and the second jaw keep the battery module firmly clamped under the action of the rope and will not loosen.

[0074] After the battery module is moved to the destination and placed, the electric hoist releases its extension and retraction, and the first clamping member 130 and the second clamping member 140 can be manually moved and released.

[0075] Rotate the swing arm 161 to the horizontal position to lock the adjusting member 150, the first clamping member 130, and the second clamping member 140.

[0076] The hoisting device of this application does not require electric or pneumatic drive, is safe and reliable, and is easy to operate. The hoisting clamp 100 is compatible with multiple square battery modules of different specifications, which improves the efficiency of assembling battery modules with the hoisting clamp 100, enhances the practicality of the hoisting clamp 100, reduces the cost of the hoisting clamp 100, and greatly reduces the difficulty of operation and labor intensity for employees.
