Since the clamping device 2, the No. 1 positioning device 3, the tooling plate 21, the toggle spring device 4 and the No. 2 positioning device 5 are directly or indirectly installed on the sliding plate 11, the sliding plate 11 drives each structure to approach the rotating loading mechanism;

[0031] The base of the relay is placed in the mounting groove 22 on the tooling plate 21, and then the cylinder on the clamping device 2 is started, so that the gripper on the front end of the clamping device 2 clamps the base, thereby fixing the base;

[0032] A plurality of movable springs are inserted on the base, and one end of the No. 1 positioning device 3 and the No. 2 positioning device 5 close to the base is located between the armature and the movable spring. First, the No. 1 positioning device 3 moves to the right, so that the distance between the armature on the relay and the movable spring increases, and the rotary loading structure is also started at the same time, and the No. 2 cylinder 62 pushes the moving plate 61 to move forward on the No. 2 bracket 6, so that the moving plate 61 drives the No. 1 servo device 7, the No. 2 servo device 8 and the rotary clamping device 9 to approach the base mechanism, and the No. 1 servo device 7 is used to drive the No. 2 servo device 8 and the rotary clamping device 9 to move left and right, and the No. 2 servo device 8 drives the rotary clamping device 9 to move up and down, and the rotary clamping device 9 includes a rotary motor device and a clamping device, wherein the clamping device is provided with a cylinder, and the cylinder can control the front end gripper of the clamping device to clamp the push card on the previous station, and the rotary motor device can drive the clamping device to rotate;
