[0028] Specifically, when the pull rod cylinder 500 operates, the piston rod 510 extends and retracts, thereby driving the upper probe mechanism 300 or the lower probe mechanism 400 to move. When the battery 210 is formed, the pull rod cylinder 500 drives the piston rod 510 to retract, and the piston rod 510 pulls the upper probe mechanism 300 to move downward, so that the upper probe 350 of the upper probe mechanism 300 is in pressure contact with the tab of the battery 210. Then, during the operation of the pull rod cylinder 500, the pull rod cylinder 500 moves upward and drives the lower probe mechanism 400 to move, so that the lower probe 440 of the lower probe mechanism 400 is in pressure contact with the tab of the battery 210, and the charging and discharging cycle is started. When the battery 210 needs to be taken out, the pull rod cylinder 500 drives the piston rod 510 to retract, and the pull rod cylinder 500 first drops until it contacts the bottom of the formation main frame 100, and the formation main frame 100 supports the pull rod cylinder 500, and the piston rod 510 drives the upper frame 310 to move upward, so that the battery tray 200 can be taken out. In this way, instead of the traditional two cylinders driving the upper probe mechanism 300 and the lower probe mechanism 400 separately, the present application uses a single cylinder to drive the movement of the upper probe mechanism 300 and the lower probe mechanism 400, so that the upper probe 350 of the upper probe mechanism 300 is in pressure contact with the tab of the battery 210, and the lower probe 440 of the lower probe mechanism 400 is in pressure contact with the tab of the battery 210, and the charging and discharging cycle of the battery 210 is completed.
