[0032] In some specific embodiments of this utility model, the transmission assembly 11 includes a swing rod 1102 rotatably connected to the front of the vertical plate 2 via a rotating shaft 1101. The top end of the swing rod 1102 is connected to the fixed frame 10, and the bottom end of the swing rod 1102 is rotatably connected to a connecting rod 1103 via a pin. The other end of the connecting rod 1103 is rotatably connected to the first movable plate 3 via a pin.

The right side of the guide rod 905 passes through the fixed block 903 and is fixedly connected to the right fixed plate 902. The guide rod 905 is slidably connected to the fixed block 903. It is easy to understand that, by setting the electric push rod 904, the fixed frame 10 and the fixed block 903 can slide left and right along the guide rod 905, thereby picking up and transferring the spring.

[0035] In some specific embodiments of this utility model, the vibratory feeding assembly 12 includes a vibratory plate 1201, and a feeder 1202 is installed at the output end of the vibratory plate 1201. The output end of the feeder 1202 has an opening 1203, which is used for the picking claw 7 to pick up the springs. It is easy to understand that by setting the vibratory plate 1201, the disordered springs can be arranged in an orderly manner and transported one by one to the track of the feeder 1202. The conveying track of the feeder 1202 is responsible for smoothly and accurately transporting the springs output by the vibratory plate 1201 to the position of the opening 1203. A photoelectric sensor is set at the opening 1203 to detect the position and state of the springs by emitting and receiving light, and to monitor the conveying status of the springs in real time, so as to provide accurate data support for the control system and adjust the working state of the vibratory feeding assembly 12 in a timely manner.

[0036] In some specific embodiments of this utility model, a first horizontal guide rail 201 is fixedly connected to the front of the vertical plate 2, a first slider 202 is fixedly connected to the back of the first movable plate 3, and the first slider 202 is slidably connected to the first guide rail 201. A second vertical guide rail 301 is fixedly connected to the front of the first movable plate 3, and a second slider 302 is fixedly connected to the back of the second movable plate 4, and the second slider 302 is slidably connected to the second guide rail 301.

[0037] In some specific embodiments of this utility model, positioning posts are fixedly connected to both the first spring fixing seat 5 and the second spring fixing seat 6. It is easy to understand that by setting positioning posts, the springs can be sleeved on the positioning posts when the grippers place them, thus preventing them from falling off during the transfer process.

[0038] Working principle: During use, the spring is placed in the vibratory feeder 1201 and then conveyed to the opening 1203 by the feeder 1202. Then, the electric push rod 904 drives the fixing block 903, the fixing frame 10, and the picking gripper 7 to move to the right to the opening 1203, clamping and fixing the spring. Next, the electric push rod 904 drives the fixing block 903, the fixing frame 10, and the picking gripper 7 to the left, allowing the picking gripper 7 to remove the spring through the opening 1203. Simultaneously, during the movement, the fixing frame 10 can drive the swing arm 1102 to rotate around the pivot 110 via the roller 1107. 1. Rotate, at this time the bottom end of the swing rod 1102 will move to the right. During the process of the bottom end of the swing rod 1102 moving to the right, it can drive the first movable plate 3 and the second movable plate 4 to move to the right through the connecting rod 1103. Since the second movable plate 4 can slide on the first movable plate 3, it is guided by the cooperation of the U-shaped groove 1104 and the guide column 1105, so that the second spring fixing seat 6 on the second movable plate 4 moves to the material picking claw 7, the first spring fixing seat 5 moves to the auxiliary claw 8, and then the material picking claw 7 places the spring on the second spring fixing seat 6. Next, the electric push rod 904 drives the picking gripper 7 to move to the right to the opening 1203, clamping and fixing the spring, and picking up the spring again. At this time, the second spring fixing seat 6 moves to the lower side of the auxiliary gripper 8, and the auxiliary gripper 8 clamps and fixes the spring on the second spring fixing seat 6. Then, the electric push rod 904 drives the picking gripper 7 to move to the left again to remove the spring. At this time, the picking gripper 7 places the spring on the second spring fixing seat 6 again, and at the same time, the auxiliary gripper 8 places the spring on the first spring fixing seat 5 to complete the picking up. Then, the picking up can be continued in the above manner. Finally, the spring that has been picked up from the first spring fixing seat 5 is picked up by the robot arm on the riveting machine and then riveted. In this way, the springs can be sent out one by one in an orderly manner, realizing automatic spring feeding, improving the efficiency of subsequent operations, and reducing the labor intensity of workers.
