[0035] The working process of a lithium battery clamping device of the present embodiment is as follows: when the lithium battery reaches the set position to be grasped, the moving mechanism of the device drives the clamping mechanism to move downward, and when it reaches the position corresponding to the lithium battery, the clamping cylinder drives the two clamping fingers to move toward each other to clamp the battery, and the clamping fingers contact the battery using the anti-slip plate. When the clamping is tightened to the clamping position sensor and is triggered, the control module receives the clamping position signal, controls the moving mechanism to drive the clamping mechanism to move upward to the highest point, and then transfers it to the placement area, and then moves downward to perform the placement operation. At this time, the occupancy sensor is used to sense whether there are other batteries occupying the placement area; if the occupancy sensor triggers and feedbacks the occupancy signal, the control module receives the occupancy signal, controls the clamping device to stop running, and issues an alarm through the alarm module; if the occupancy sensor is not triggered, the control module controls the moving mechanism to drive the clamping mechanism to move downward to the set position, and then the clamping cylinder drives the two clamping fingers to move apart to release the battery, that is, the placement is completed; wherein, due to individual differences in batteries and loose clamping, the upper and lower positions of the lithium battery after clamping will be misaligned. During the placement process, the bottom of the lithium battery will first Contact the placement platform. At this time, if the lithium battery is placed directly, it will cause crushing to the lithium battery, but the buffer mechanism and buffer in place sensor of this embodiment can solve this problem; when the clamping position of the lithium battery is lower, the lithium battery will contact the placement platform in advance, but because it is in advance contact, the moving mechanism will continue to drive the clamping cylinder and the clamping fingers to continue to move downward according to the setting. At this time, the clamping fingers will remain motionless under the action of the buffer structure, and the buffer in place trigger end of the buffer in place sensor will gradually approach the buffer in place sensing end. If the degree of downward deviation of the position does not reach the triggering of the buffer in place sensor, it will continue to proceed according to the setting; if the degree of downward deviation of the position is too large, when the buffer in place sensor is triggered, the control module receives the buffer in place signal, controls the moving mechanism to drive the clamping mechanism to move to the high point and then stop running, and sends an alarm through the alarm module; after the clamping mechanism grabs the lithium battery and before placing the lithium battery, the through-shooting sensor will detect in real time whether the lithium battery has fallen. When the through-shooting sensor is triggered due to the falling of the lithium battery, the control module receives the lithium battery falling signal, stops the action of the clamping device, and sends an alarm through the alarm module.
