[0040] The welded battery string is transmitted on the conveying assembly 5, and the sensing element 211 senses the position of the battery string. The cylinder 201 slides along the guide rod 202 according to the sensing result, thereby driving the cylinder connecting plate 203 and the slider 205 to slide along the slide rail 2000, and further driving the sliding seat 206 connected to the cylinder connecting plate 203, the base 208 connected to the sliding seat 206, and the shooting element 207 arranged on the base 208 to move and shoot with the battery string, and feed the shot pictures to the external system for analysis and judgment, and display them on the display element 3.
