The rotary driving executing piece drives the suckers at two ends in the corresponding processing host respectively to be positioned above the feeding and discharging stations A and 100 or above the feeding and discharging stations A and 200 respectively. Specifically, the rotary drive actuator is a motor or a cylinder. By setting the rotation arm 410 to be L-shaped, both ends can be provided with suction cup structures, and thus loading and unloading can be performed simultaneously. When the device is specifically operated, when one of the suckers at two ends is located above the feeding and conveying assembly line 100, and the other sucker is located above the feeding and discharging station A, the suckers at two ends respectively acquire the battery pieces to be processed on the feeding and conveying assembly line 100 and the battery pieces after being processed, then the rotary driving executing piece drives the rotary arm 410 to rotate, at the moment, one sucker at two ends is located above the feeding and discharging station A, the other sucker at two ends is located above the discharging and conveying assembly line 200, at the moment, the suckers at two ends respectively place the battery pieces to be processed on the bearing table 322 corresponding to the feeding and discharging station A and the battery pieces after being processed on the discharging and conveying assembly line 200, and then the rotary arm 410 rotates again to repeat the processes.

Correspondingly, the laser processing module 320 in the second host 2 in this embodiment includes two laser processing units, which are respectively located at two processing stations B in the second host 2, that is, the apparatus has four laser processing units (lasers) that can work simultaneously, so as to further improve the working efficiency.

As another embodiment, the second host machine 2 is different from the first host machine 1, the second host machine 2 has one loading and unloading station a, the number of processing stations B is not limited to one, and may be one or two, the number of carrying platforms 322 in the second host machine 2 is four, and the four carrying platforms 322 are arranged at 90 ° intervals, and at this time, the supporting frame of the turntable module 310 in the second host machine 2 in this embodiment may be regarded as a cross, and the rotation driving mechanism 321 of the second host machine 2 drives each carrying platform 322 to rotate for 90 ° once. Considering that there is only one loading and unloading station a, the number of suction cups in the suction cup mechanism corresponding to the second host 2 at this time may be one, i.e. one battery piece is loaded at a time. Correspondingly, the laser processing module 320 in the second host 2 in this embodiment includes at least one laser processing unit, that is to say the apparatus has at least three laser processing units (lasers) that can be operated simultaneously. For example, as shown in fig. 2, the number of processing stations B is one, and the apparatus has three laser processing units (lasers) that can be operated simultaneously.

As another embodiment, considering that the distance between the feeding and discharging transfer lines 100 and 200 is insufficient, the bottom of the carrying table 322 of the first host 1 is higher than the feeding and discharging transfer lines 100 and 200, so that the carrying tables 322 will not collide with the feeding and discharging transfer lines 100 and 200 during the rotation process even if the distance between the feeding and discharging transfer lines 100 and 200 is small.

Considering that the loading and unloading conveying assembly line 100, the unloading conveying assembly line 200 and the carrying table 322 are not at the same level, the rotary conveying module 400 corresponding to the first host machine 1 further comprises a lifting driving mechanism (not shown in the figure), the L-shaped rotary arm 410 corresponding to the first host machine 1 is connected with the lifting driving mechanism, the L-shaped rotary arm 410 in the rotary conveying module 400 corresponding to the first host machine 1 is divided into a first moving arm and a second moving arm, when the lifting driving mechanism drives the sucker mechanism at the end part of the first moving arm to be located above the loading and unloading conveying assembly line 100 and the sucker mechanism at the end part of the second moving arm to be located above the loading and unloading station A, and when the lifting driving mechanism drives the sucker mechanism at the end part of the first moving arm to be located above the loading and unloading station A and the sucker mechanism at the end part of the second moving arm to be located above the unloading conveying assembly line 200, the first moving arm is higher than the second moving arm. Whether the first moving arm is lower than the second moving arm or the first moving arm is higher than the second moving arm, the heights of the suckers at the end parts of the two moving arms are mainly indicated, and therefore, when the positions of the suckers are switched to adapt to the situation that the feeding conveying assembly line 100, the discharging conveying assembly line 200 and the bearing table 322 are not at the same horizontal height, the suckers can better absorb or release the battery pieces. Furthermore, the lifting driving mechanism can drive the two moving arms simultaneously for one driving executing piece, at the moment, the working process is realized through the design of the mechanical mechanism, and the lifting driving mechanism can also comprise two driving executing pieces for ensuring that the two driving executing pieces respectively drive one moving arm to move in a lifting manner, so that the height position switching at different stations is realized. Further, the driving actuator in the lifting driving mechanism may be a motor or a cylinder, and the connection manner between the lifting driving mechanism and the L-shaped rotating arm 410 may be various, so long as the above-mentioned functions can be achieved. Through the rotary carrying module 400 with the structure, the loading and unloading carrying of the battery piece is realized when the loading and unloading carrying assembly line 100, the unloading carrying assembly line 200 and the bearing table 322 are not at the same horizontal height, and the space in the direction vertical to the first direction can be further saved.
