In this embodiment, the material conveying direction is from left to right, and the mechanical material taking hand 723 is provided with three.
Specifically, during operation, firstly, the first feeding mechanism 21 conveys the battery core to an upper material level, then the second linear driving member 714 drives the first material taking claw 715 to move downwards, so as to adsorb the battery core, and after adsorption, the second linear driving member 714 drives the first material taking claw 715 to lift the battery core upwards; then, the first linear module 711 drives the first material taking claw 715 adsorbed with the battery core to move to the vacuum-pumping packaging mold 31, and then material is discharged, and after the material discharge is finished, the material is reset to perform the next cycle.
In the resetting process, the vacuumized packaging mold 31 rotates 180 degrees until another vacuumized packaging mold 31 reaches the packaging position, and meanwhile, the second linear module 721 drives the transfer platform 722 to move leftwards to the initial position, and at this time, from left to right, the three mechanical material taking hands 723 are respectively opposite to the vacuum packaging assembly 3, the blanking assembly 4 and the fine packaging assembly 5. Then the vacuum packaging assembly 3 is opened, and the blanking assembly 4 and the fine packaging assembly 5 are in a state to be processed after the operation is finished. At this time, the three mechanical material taking hands 723 work simultaneously, at this time, the fourth linear driving element 7235 extends to drive the second material taking claw 7236 to move to the corresponding processing assembly simultaneously, after the material taking claw moves to the designated position, the third linear driving element 7235 extends to drive the second material taking claw 7236 to move downward to the designated position, then the second material taking claw 7236 adsorbs the battery cell, then the third linear driving element 7235 and the fourth linear driving element 7236 sequentially contract to lift the battery cell, then the second linear module 721 drives the transfer platform 722 to move rightward and convey the battery cell to the next station, after the designated position is reached, the material discharging operation of the battery cell is operated, that is, the fourth linear driving element 7235 extends to drive the second material taking claw 7236 to move to the corresponding processing assembly, after the battery cell moves to the designated position, then the third linear driving element 7235 extends to drive the second material taking claw 7236 to move downward to the designated position, then the second material taking claw 726 discharges the battery cell to the processing area, resetting after the placement; at the same time, the first transport mechanism 71 has taken the cells from the feeding assembly 2 and has discharged the cells to the encapsulation area.
In the embodiment, whether each structure moves in place or not can be judged by the sensor.
To sum up: through mutually supporting between first feed mechanism 21 and the second feed mechanism 22 carry out the material of alternately circulating, avoid leading to the condition that the machine needs to wait because of artifical material loading operation error to improved production efficiency, material loading direction and material direction of delivery mutually perpendicular have utilized the area of frame 1 to a great extent moreover, thereby shortened the length of whole device greatly, thereby improved space utilization.
