[0026] In this embodiment, it should be noted that: when the springs are unloaded, the springs are selectively poured into the first feeding chamber 101 or the second feeding chamber 102 according to the subsequent boxing needs or usage needs.

[0027] After the spring is poured into the first feeding chamber 101, it falls into the quantitative storage chamber 303 along the funnel-shaped first feeding chamber 101 until the spring completely covers the internal storage volume of the quantitative storage chamber 303. At this time, the camera 301 monitors the spring capacity inside the quantitative storage chamber 303 in real time, processes the image information of the quantitative storage chamber 303 filled with springs, and sends an electrical signal to the PLC controller. The model of the PLC controller is: "6ES7216-2BD23-0XB8". After receiving and processing, the PLC controller sends the processed electrical signal to the electric control telescopic rod 302, and the electric control telescopic rod 302 starts to drive the movement The rod 308 moves. At this time, the first extrusion block 309 is close to the first curved plate 307, and the second extrusion block 313 is close to the second curved plate 312. The front ends of the two extrusion blocks are both circular, so the two curved plates will be pushed outward during extrusion. At this time, the plug plate 305 is pushed toward the slot 304, and the sealing plate 310 is pushed into the docking groove 311.

When the second feeding chamber 102 falls on the replaceable guide plate 401, it will fall downward through the guide tube 402. At the same time, the number of falling springs is monitored in real time by the number sensor 404. When the set number is reached, the electric telescopic rod 403 is started, and the execution end seals the bottom end of the second feeding chamber 102.

[0029] Implementation three: Reference Figure 1 , Figure 3 as well as Figure 5 Compared with the first and second embodiments, in the present embodiment: the anti-blocking component 6 is used to shake the feeding box 1 to prevent the first feeding chamber 101 and the second feeding chamber 102 from being blocked during the spring feeding process.

[0031] When loading the spring, since the spring is a special-shaped workpiece, it is easy to get stuck at the feeding port when unloading. By executing the motor 601 to drive the gear plate 602 to rotate, and then drive the conveyor chain 603 to rotate and drive the docking gear 604, i.e. the fixed rod 605 and the feeding box 1 to shake, the spring can be shaken away to prevent blockage.
