The sliding block 41 is sleeved on the sliding rail 11 and slides relative to the sliding rail 11 along the first direction X under the driving of the driving mechanism 2. Each group of clamping assemblies 4 is provided with two sliding rails 11 distributed along the Y direction, and one sliding block 41 is sleeved on each sliding rail 11.

Along the X direction, one cylinder 21 is arranged on each side of the support 1, respectively driving the clamping assembly 4 on each side to move.

[0049] Optionally, referring to Figure 1 , the hoisting tool further comprises a first controller 6; the first controller 6 is electrically connected with the cylinder 21, and is used for controlling the opening and closing of the cylinder 21.

[0050] Specifically, as shown in Figure 1 , the first controller 6 can be directly connected with the support 1 or indirectly connected with the support 1 through other connecting structures, so as to avoid occupying too much installation space. The first controller 6 is electrically connected with the cylinder 21 and the vacuum generator 31, and is used for controlling the start and stop of the cylinder 21 and the vacuum generator 31.

The form of the lifting mechanism can include but is not limited to a gourd lifting machine, a hydraulic lifting machine or a steel wire rope lifting machine. The second controller 7 is electrically connected with the lifting mechanism, and the second controller 7 can be directly connected with the support 1 or indirectly connected with the support 1 through other connecting structures, and is used for controlling the lifting mechanism to ascend, descend or stop urgently along the Z direction.

[0060] In some embodiments, in combination with Figure 1 and Figure 4 , the battery module hoisting and carrying work is performed by using the hoisting tooling provided by the embodiment by the following steps:

[0061] Step one, the operator operates the second controller 7 to control the lifting mechanism to rise and fall, and moves the hoisting tool to above the battery module 8 and makes the vacuum suction cup 32 contact with the upper surface of the battery module 8.

[0062] Step two, the positioning member 5 is inserted and positioned with the battery module 8.

[0063] Step three, the operator controls the clamping button 62 of the first controller 6, so that the air cylinder 21 drives the clamping plates 43 on both sides to move towards each other along the X direction to clamp the battery module 8, specifically, the left clamping plate 43 moves along the positive X direction, the right clamping plate 43 moves along the negative X direction, and the clamping plates 43 on both sides approach each other until the battery module 8 is clamped on both sides, and meanwhile the insertion column 44 is inserted into the insertion slot 81 of the end plate of the battery module 8 to fix the battery module 8.

[0064] Step four, when the operator opens the negative pressure knob 61, the vacuum suction cup 32 forms a negative pressure adsorption effect and is adsorbed on the upper surface of the battery module 8.

[0065] Step five, the second controller 7 controls the lifting mechanism to rise and fall, and the hoisting tool carries the battery module 8 to the preset position for subsequent assembly process.

[0066] Therefore, when the hoisting tool provided by the embodiment is used to hoist and carry the battery module, the automation degree is high, the actions of the air cylinder and the vacuum suction cup are controllable to control the hoisting process, and the production efficiency is higher than that of the conventional technology of manually operating the clamp. Moreover, the clamping of the clamping plate and the adsorption of the suction cup are mutually matched to improve the stability and safety in the hoisting process and effectively reduce the risk of damage or falling of the module caused by the loosening of the steel belt.
