The torsion spring 0 is supplied by the torsion spring feeding mechanism 1, the material is taken by the material taking mechanism 3 and is sent to the torsion mechanism 4, then the torsion mechanism 4 enables the torsion spring 0 to be twisted open, then the torsion spring is sent to the feeding mechanism 5, and finally the feeding mechanism 5 keeps the torsion spring 0 in posture and sends the torsion spring 0 to the target position of the circuit breaker.

As shown in fig. 2 to 3, the torsion mechanism 4 includes a positioning rod 41, a pushing tube 42, a stationary buckle 43, a movable buckle 44, a movable buckle sleeve 45, and a movable buckle rotation driving member 46. The outer diameter of the positioning rod 41 at the central position of the positioning rod 41 is smaller than the inner diameter of the untwisted torsion spring 0, and the received torsion spring 0 is sleeved outside the positioning rod 41. The material pushing pipe 42 is movably sleeved outside the positioning rod 41, the material pushing pipe 42 abuts against a torsion spring 0 outside the positioning rod 41 when pushing materials, namely the inner diameter of the material pushing pipe 42 is smaller than the inner diameter of the torsion spring 0 which is not twisted open, the outer diameter of the material pushing pipe is larger than the outer diameter of the torsion spring 0, the bottom end of the material pushing pipe 42 is also connected with a material pushing pipe 42 driving cylinder which drives the material pushing pipe 42 to push materials, and the material pushing pipe 42 is driven by the material pushing pipe 42 driving cylinder to enable the material pushing pipe 42 to lift axially.

When the positioning rod 41 receives the torsion spring 0, the torsion spring 0 freely falls onto the movable buckle sleeve 45 outside the positioning rod 41, at this time, the movable buckle rotary driving piece 46 drives the movable buckle sleeve 45 to rotate, the movable buckle 44 is driven to rotate towards the static buckle 43, the central angle between the movable buckle 44 and the static buckle 43 is reduced, the movable buckle 44 and the static buckle 43 can be naturally abutted against the support arms 01 at the two ends of the torsion spring 0 in the rotating process of the movable buckle 44, the torsion spring 0 can be twisted off along with the further rotating action of the movable buckle 44, then the pushing pipe 42 is lifted to push up the twisted-off torsion spring 0, and the torsion spring 0 is separated from the positioning rod 41 to the feeding mechanism 5. In order to facilitate the insertion of the torsion spring 0 into the positioning rod 41, the movable catch 44 needs to approach the stationary catch 43 in the reverse rotation direction at a position before the start of the operation, so that the central angle between the movable catch 44 and the stationary catch 43 is maximized. The material pushing pipe 42 and the static buckle 43 are magnetized parts, the material pushing pipe 42 and the static buckle 43 are magnetic and can adsorb the torsion spring 0, the magnetism of the static buckle 43 is used for enabling one end part of the torsion spring 0 to be tightly attached to the static buckle 43 when the torsion spring 0 is placed on the positioning rod 41, the placing direction of the torsion spring 0 can be positioned, and the magnetism of the material pushing pipe 42 is used for enabling the torsion spring 0 to be tightly attached to the top of the material pushing pipe 42 and positioning the placing position of the torsion spring 0. From another perspective, when the torsion spring 0 fails to enter the feeding mechanism 5, the material pushing pipe 42 may also suck the torsion spring 0 to return, and push the torsion mechanism 4 out after twisting open again.

One side of the notch 511 is close to and flush with the working surface of the static buckle 43 when the feeding mechanism 5 receives the torsion spring 0, and the other side of the notch is close to and flush with the working surface of the movable buckle 44 after the rotation is finished, so that the torsion spring 0 twisted on the static buckle 43 and the movable buckle 44 can be smoothly and stably pushed into the notch 511. Certainly, in order to ensure the smooth displacement of the torsion spring 0, the twisting angle of the static buckle 43 and the dynamic buckle 44 can be properly reserved, so that the twisting central angle of the twisting mechanism 4 is slightly smaller than the central angle of the groove wall of the notch 511. The support arm 01 of the torsion spring 0 abuts against the groove wall of the notch groove 511, the torsion spring 0 is sleeved on the torsion spring guide post 53, the torsion spring 0 keeps a twisting-open posture, when the feeding mechanism 5 reaches the position above the target position, the notch groove 511 abuts against the target position, and the feeding and discharging pipe 52 pushes the torsion spring 0 downwards to press the torsion spring 0 into the target position.

When material is taken, the material taking mechanism 3 is close to the discharge port of the torsion spring feeding mechanism 1, the material taking guide pillar 31 moves downwards and is inserted into the torsion spring 0, the chamfer 311 gradually enters the torsion spring 0, the chamfer 311 needs to extrude the torsion spring 0 due to the increase of the outer diameter of the chamfer 311, the torsion spring 0 is tightly sleeved on the material taking guide pillar 31 due to the elastic restoring force of the torsion spring 0, then the material taking guide pillar 31 moves the torsion spring 0 to the torsion mechanism 4, and the material taking falling pipe 32 pushes the torsion spring 0 downwards to be sleeved on the positioning rod 41.

The shape imitating positioning block is fixed at the top of the fixed workbench 64, a shape imitating positioning cavity 631 which imitates the shape of the torsion spring 0 and determines the placement direction of the support arm 01 of the torsion spring 0 is arranged in the shape imitating positioning block 63, and the shape imitating positioning cavity 631 is communicated with a discharge hole of the torsion spring feeding mechanism 1. The torsion spring feeding mechanism 1 supplies a torsion spring 0 to the working surface of the fixed workbench 64 at a discharge port thereof, the profiling positioning cavity 631 guides the torsion spring 0 to a set placing direction thereof, then the material taking guide pillar 31 descends and is inserted into the torsion spring 0, meanwhile, the floating pin 61 is stressed to press the spring 62 to contract, the torsion spring 0 is sleeved on the material taking guide pillar 31 through the chamfer 311 of the material taking guide pillar 31 and taken out from the profiling positioning cavity 631, and the floating pin 61 is reset due to the action of the spring 62. Therefore, the torsion spring 0 is more easily sleeved on the material taking guide post 31, and the phenomenon of empty material is avoided. On the other hand, the shape of the profiling positioning cavity 631 is formed to be arranged to follow the shape of the torsion spring 0, and the position of the support arm 01 of the profiling positioning cavity 631 is determined to be a certain position, so that the profiling positioning cavity 631 can preliminarily determine the placement position of the support arm 01 of the torsion spring 0. Because the subsequent displacement does not basically change the placing direction of the support arm 01 of the torsion spring 0, and the placing direction of the support arm 01 of the torsion spring 0 guided by the profiling positioning cavity 631 is the placing direction before the torsion mechanism 4 is reached next, the placing direction of the support arm 01 of the torsion spring 0 guided by the profiling positioning cavity 631 can be designed to avoid that the support arm 01 of the torsion spring 0 is too close to the static buckle 43, and the torsion spring 0 is prevented from being clamped on the static buckle 43 when being placed to the torsion mechanism 4.
