Referring to fig. 1, an embodiment of the present application provides a welding scheduling device 10. The welding scheduling device 10 includes a first visual inspection device 110, a control device 130, and a plurality of second visual inspection devices 140. The first visual inspection device 110 is configured to identify first coordinate information of each cell welding spot 121 in the battery module 120 relative to a feature point of the battery module 120. The control device 130 is configured to determine a target welding machine 150 according to states of different welding machines 150, and control the battery module 120 to be transported to the target welding machine 150. The second visual inspection devices 140 are fixedly arranged relative to the welder 150, and configured to identify a feature point of the battery module 120 transported to the target welder 150, and convert the first coordinate information into second coordinate information of the cell welding spot 121 relative to the feature point according to the feature point. And the target welding machine 150 performs positioning welding on the cell welding spot 121 according to the second coordinate information.
In this embodiment, the first visual inspection device 110 may be a high-precision visual inspection apparatus. Referring to fig. 2, the battery module 120 may be provided with a plurality of cell pads 121. The welding machine 150 can connect different cell pads 121.

In the welder scheduling apparatus 10 provided in the embodiment of the application, the first visual inspection device 110 may identify first coordinate information of each cell welding spot 121 in the battery module 120 relative to a feature point of the battery module 120. The feature point can be identified by the second visual inspection device 140, and the first coordinate information is converted into the second position information of the cell welding spot 121 relative to the feature point at the position of the target welding machine 150. Therefore, the second visual inspection device 140 can determine the position of the cell solder joint 121 relative to the target welding machine 150 only by identifying the feature points, and a complex identification process is not required, and the identification process is simple, so that the identification efficiency and the identification accuracy can be improved.

In this embodiment, the identification code 151 may be an identification mark such as a two-dimensional code. The identification code 151 may be fixedly disposed with respect to the battery module 120. The identification code 151 moves with the battery module 120 when the battery module 120 is transported. The identification code 151 represents the unique first identity information of the battery module 120. The control device 130 may store the first identity information therein. The scanning device may be disposed on a path through which the battery module 120 passes. Before the battery module 120 is transported to the welder 150, the control device 130 may preset a travel path of the battery module 120 according to the operating state of the welder 150. When the battery module 120 is about to reach the target welder 150, the identification code 151 is identified again by the code scanning device 152 and the second identity information is generated. If the second identity information corresponds to the first identity information, it indicates that the travel path of the battery module 120 is correct, and the corresponding target welding machine 150 is also correct, so that a normal work flow can be performed. If the second identity information is different from the first identity information, it indicates that the transportation path of the battery module 120 is wrong, and it is necessary to correct the route or suspend the operation of the assembly line.

It is understood that, when the code scanning device 152 is disposed on the transportation device 160, the identity information of the battery module 120 can be scanned and confirmed by the code scanning device 152 when the transportation device 160 transports the battery module 120.

The rf reader/writer 172 is fixed to the welder 150, and configured to read the first coordinate information and transmit the first coordinate information to the second visual inspection device 140. The first coordinate information may be stored in the rfid chip 171. After the rfid chip 171 is transported to the welding machine 150 along with the battery module 120, the first coordinate information is read by the rf reader/writer 172 and transmitted to the second visual inspection device 140. The second visual inspection device 140 converts the first coordinate information into the second coordinate information. The rfid chip 171 has high recognition accuracy and is not prone to error. The first coordinate information is stored and transported by the rfid chip 171, and is directly read by the rf reader/writer 172, so that the separation of physical distribution and data can be avoided, and errors caused by intermediate data transmission can be avoided.
And the radio frequency identification chip 171 is used for directly transmitting the first coordinate information in a transportation mode, so that the transmission links among information can be reduced, and the signal loss and the error probability are reduced.
