In this embodiment, the plurality of battery row conveying pipelines are sequentially connected in a line-shaped arrangement. It should be noted that the assembly line in the battery row conveying apparatus 1100 is obtained by sequentially connecting a plurality of battery row conveying assembly lines 1110, so that each battery row conveying assembly line 1110 is independent from another and driven by an independent power unit, the battery row conveying assembly lines 1110 can be flexibly increased or decreased, and various problems caused by an excessively long integral assembly line can be prevented, for example, the integral assembly line can generate huge vibration due to the excessively placed battery rows, and the vibration can be reduced by providing a plurality of independent battery row conveying assembly lines 1110.

Specifically, the battery row extracting robot 1120 includes: the battery row taking and transferring module 1121, the battery row taking and transferring jaw 1122, and the battery row taking and transferring module 1121 drives the battery row taking and transferring jaw 1122 to move.
Here, the operation principle of the battery row transfer mechanism 1000 will be explained:
each battery row conveying device 1100 is in one-to-one correspondence with each battery splicing device of the previous station;
the battery row taking and transferring module 1121 drives the battery row taking and transferring clamping jaw 1122 to move, so that a battery row of a battery splicing device in the previous station is taken into the battery row conveying assembly line 1110, and then the battery row conveying assembly line 1110 conveys the battery row to a specified position to wait for the loading and assembly of the battery row;
since the plurality of battery bank transfer lines 1110 are sequentially coupled together, some battery banks need to pass through the plurality of battery bank transfer lines 1110 to be transferred to a designated location, and therefore, particularly, a battery row isolation positioning structure 1130 is provided, the battery row isolation positioning structure 1130 is located at the joint of the battery row conveying line 1110, when one of the battery row reclaiming robots 1120 needs to reclaim a battery row onto the battery row transfer line 1110, the battery bank isolation positioning driving unit 1131 on the current battery bank transport line 1110 drives the battery bank isolation positioning rod 1132 to extend, so as to block the battery bank to be transported by the previous battery bank transport line 1110, prevent the previous battery bank from flowing into the current battery bank transport line 1110, so that the current battery row extracting robot 1120 can smoothly extract the battery row to the current battery row conveying line 1110.
In the embodiment, the battery row isolation positioning driving part is a cylinder driving structure; the end of the battery row isolation positioning rod 1132 is provided with an anti-collision elastic piece (not shown), and the battery row can be effectively protected from being damaged by the anti-collision elastic piece.
Further, the battery row conveying device 1100 further includes a battery row discharging safety grating (not shown), and the battery row discharging safety grating is disposed on the battery row conveying line 1110. The battery row blanking safety grating is used for detecting whether a battery row exists in a blanking area of the battery row conveying line 1110, and the battery row material taking manipulator 1120 can safely take the battery row to the battery row conveying line 1110 only when the battery row does not exist in the blanking area.
As shown in fig. 4, further, the battery row conveying mechanism 1000 further includes a battery row position detecting device 1200. The battery row in-place detection apparatus 1200 includes: the battery row arrival position detection system comprises a battery row arrival position placing platform 1210, a battery row arrival position proximity switch 1220 and a battery row state visual detection system 1230, wherein the battery row arrival position placing platform 1210 is positioned at one end of a plurality of battery row conveying pipelines 1110 which are sequentially connected, the battery row arrival position proximity switch 1220 is arranged on one side, away from the battery row conveying pipelines 1110, of the battery row arrival position placing platform 1210, and the battery row state visual detection system 1230 is positioned above the battery row arrival position placing platform 1210. When the battery row reaches the battery row in-place placement platform 1210, the battery row touches the battery row in-place proximity switch 1220, a developed signal of the battery row in-place proximity switch 1220 is sent to the control center, the control center controls the battery row state visual detection system 1230 to photograph the structure of the current battery row, and the latter station can conveniently judge whether the current battery row needs to be adjusted or not, so that the battery row can be smoothly spliced into a battery layer.
In the production process, the lengths of the battery rows of different models can be different. In order to better match the battery row state vision detection system 1230 to photograph the battery row, the in-place detection point of the battery row needs to be adjusted.

Next, a specific structure of the cell row stack mechanism 2000 will be explained:
first, as shown in fig. 5, a battery layer structure 20 is obtained by sequentially splicing a plurality of rows of battery rows 21. In the actual production process, the number of the batteries in the last battery row is two less than that of the batteries in other battery rows, so that two batteries need to be taken out of the last battery row to meet the production requirement.
It should be noted that the battery row 21 is formed by splicing a plurality of batteries, and the splicing between the batteries needs to be performed by the splicing block 22. The splicing blocks 22 are provided with a male slot 23 and a female slot 24, and splicing of one splicing block 22 and the other splicing block 22 is realized by clamping the male slot 23 and the female slot 24. As can be seen from fig. 6, the two battery rows to be spliced can be spliced only when the adjacent surfaces of the two corresponding splicing blocks are respectively the male groove and the female groove. As shown in fig. 7, if the adjacent surfaces of two corresponding splicing blocks of two battery rows to be spliced are both male grooves or both female grooves, it is impossible to splice the battery rows.
In order to better solve the above problems in the production, the structure of the cell row stack layer mechanism 2000 is optimally designed.

As can be seen, the battery row assembling manipulator 2100 is used for taking a battery row in a previous station, or placing the battery row in the battery row taking area 2200, or placing the battery row in the battery row waiting area 2300, or placing the battery row assembling layer in the battery row assembling layer 2400. If the current bank needs to be placed in the last bank of battery layers, then the battery bank is placed in the bank battery region 2200, and two batteries are taken out from the current bank; if the current battery row does not meet the requirement of splicing, namely the male and female grooves between the battery rows do not correspond, arranging the battery rows in a battery row material waiting area 2300 to wait for proper time for splicing; if the current battery row meets the requirement of splicing, the battery row is directly placed in the battery row assembly layer region 2400, and splicing of the battery row and the battery row is achieved.
Thus, the purpose of providing the battery bank status visual detection system 1230 in the battery bank transport mechanism 1000 can be well explained. The battery row state visual detection system 1230 is configured to identify a structural state of a current battery row, that is, whether the current battery row is suitable for pairing with a battery row to be spliced, if so, the battery row is transferred to the battery row assembly layer 2400 by the battery row assembly manipulator 2100, and if not, the battery row is transferred to the battery row standby region 2300 by the battery row assembly manipulator 2100.

Thus, when a certain battery in the battery row needs to be taken out, the battery taking first positioning column 2244 or the battery taking second positioning column 2245 can hold the battery adjacent to the certain battery, and the battery taking driving part 2242 drives the battery taking clamping jaw 2243 to stably complete the work of taking out the battery under the cooperation of the battery taking first positioning column 2244 or the battery taking second positioning column 2245.
