The sub-rotating plate 21 is provided with a plurality of lower molds 211 for accommodating the lower end of the torsion spring. Fig. 9 The lower mold 211 is provided with a rotation-limiting protrusion 2111 that cooperates with the bayonet at the lower end of the torsion spring. Figure 3 The rotary drive device 22 drives the sub-turntable 21 to rotate, so that the lower mold 211 passes through the loading mechanism 30, the correction mechanism 40, the twisting mechanism 50, and the unloading mechanism 60 in sequence.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 The feeding mechanism 30 is disposed on the frame 10 and located on one side of the rotating worktable 20 , and the feeding mechanism 30 is used to transport the torsion spring to the lower mold 211 .

[0030] Please refer to Figure 5 The correction mechanism 40 is arranged on the frame 10 and located on one side of the rotating table 20. The correction mechanism 40 includes an upper mold A41 and a correction drive device 42. The correction drive device 42 drives the upper mold A41 to move with the lower mold 211 and rotate the upper mold A41 so that the lower end of the torsion spring is locked into the rotation-limiting protrusion 2111 of the lower mold 211.

[0031] Please refer to Figure 7 The twisting mechanism 50 is disposed on the frame 10 and located on one side of the rotating table 20. The twisting mechanism 50 includes an upper mold B51 and a twisting driving device 52. The twisting driving device 52 drives the upper mold B51 to fit with the lower mold 211 and twists the torsion spring to form.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 The unloading mechanism 60 is disposed on the frame 10 and located on one side of the rotating worktable 20 , and the unloading mechanism 60 takes the torsion spring out of the lower mold 211 .

[0033] Implementation process: The torsion spring with twist is transported from the feeding mechanism 30 to the lower mold 211 located on the rotating worktable 20. The rotary drive device 22 drives the sub-turntable 21 to rotate, so that the lower mold 211 passes through the correction mechanism 40. The correction drive device 42 drives the upper mold A41 to match the lower mold 211 and rotate the upper mold A41, so that the lower end of the torsion spring is clamped into the rotation-limiting clamping protrusion 2111 of the lower mold 211. At this time, the rotation of the torsion spring is limited by the rotation-limiting clamping protrusion 2111 of the lower mold 211. The rotary drive device 22 drives the sub-turntable 21 to rotate, so that the lower mold 211 passes through the twisting mechanism 50. The twisting drive device 52 drives the upper mold B51 to match the lower mold 211 and twist to form the torsion spring. The rotary drive device 22 drives the sub-turntable 21 to rotate, so that the lower mold 211 passes through the unloading mechanism 60, and the unloading mechanism 60 takes the twisted torsion spring out of the lower mold 211.

[0034] Please refer to Figure 2 and Figure 3 The feeding mechanism 30 includes a vibration plate 31, a guide groove 32 and a feeding manipulator 33. The guide groove 32 is connected to the vibration plate 31 at its beginning. The feeding manipulator 33 obtains the torsion spring from the guide groove 32 and transfers the torsion spring to the lower mold 211. The feeding manipulator 33 includes a feeding moving module 331, a feeding lifting module 332 and a feeding clamping cylinder 333. The feeding lifting module 332 drives the feeding clamping cylinder 333 to clamp the torsion spring downward from the guide groove 32. The feeding lifting module 332 drives the feeding clamping cylinder 333 to rise. The feeding moving module 331 drives the feeding lifting module 332, the feeding clamping cylinder 333 and the torsion spring to move above the lower mold 211. The feeding lifting module 332 drives the feeding clamping cylinder 333 to descend and put the torsion spring into the lower mold 211.

[0035] The guide groove 32 is a vibration guide groove, and a guide block (blocked in the figure) is provided at the end of the guide groove 32. A guide groove connected to the guide groove 32 is provided on the guide block. A push block 322 and a thrust cylinder 321 connected to the push block 322 are provided at one opening of the guide groove. A positioning block 323 is provided at the other end of the guide groove. When the torsion spring enters the guide groove from the guide groove 32, the thrust cylinder 321 pushes the push block 322 and pushes the torsion spring onto the positioning block 323, thereby positioning the torsion spring to facilitate the grabbing of the feeding robot 33.

[0036] The rotary drive device 22 of the rotary table 20 includes a rotary drive motor and a reduction box connected to the rotary drive motor, and the sub-rotating disc 21 is arranged on the output shaft of the reduction box to increase the output torque. The outer ring area of ​​the sub-rotating disc 21 is evenly distributed with a plurality of hollow holes, and the width of the hollow holes gradually increases from the center of the sub-rotating disc 21 to the outside to ensure its rigidity and reduce its weight.

[0037] The upper mold A41 and the upper mold B51 are both provided with a first groove for accommodating the upper end of the torsion spring, and a first protrusion is formed in the first groove. The lower mold 211 is provided with a second groove 2112 for accommodating the lower end of the torsion spring, and the rotation-limiting protrusion 2111 is disposed in the second groove 2112.

[0038] Please refer to Figure 3 , Figure 5 and Figure 6 The correction drive device 42 includes a first lifting drive member 421, a first lifting plate 422, a first rotation drive member 423 and a first rotation shaft 424. The first lifting drive member 421 drives the first lifting plate 422 to rise and fall, the first rotation drive member 423 is disposed on the first lifting plate 422, the first rotation drive member 423 drives the first rotation shaft 424 to rotate, and the upper mold A41 is disposed on the first rotation shaft 424.

[0039] When the twisted torsion spring is placed on the lower mold 211 by the feeding mechanism 30, the bayonet at the lower end of the torsion spring cannot be accurately aligned with the rotation-limiting bayonet 2111, and the rotary drive device 22 drives the sub-turntable 21 to rotate, so that the lower mold 211 passes through the correction mechanism 40. The first lifting drive member 421 drives the first lifting plate 422 to descend, and the first rotary drive member 423, the first rotary shaft 424 and the upper mold A41 provided on the first lifting plate 422 follow the decline, so that the upper end of the torsion spring extends into the first groove of the upper mold A41. The first rotary drive member 423 drives the first rotary shaft 424 and the upper mold A41 to rotate, and during the rotation process, when the first protrusion of the upper mold A41 is aligned with the bayonet at the upper end of the torsion spring, the first protrusion is engaged with the bayonet at the upper end of the torsion spring. The upper mold A41 continues to rotate to drive the torsion spring to rotate together until the bayonet at the lower end of the torsion spring A is aligned with the rotation limit protrusion 2111 of the lower mold 211, so that the bayonet at the lower end of the torsion spring is inserted into the rotation limit protrusion 2111 of the lower mold 211 to complete the correction and positioning of the torsion spring, facilitating the subsequent torsion processing of the torsion mechanism 50.

[0040] The first rotating shaft 424 includes an upper shaft section 4241 and a lower shaft section 4242. A first elastic member (not shown in the figure) is provided at the connection between the upper shaft section 4241 and the lower shaft section 4242. The first elastic member is used to elastically connect the upper shaft section 4241 and the lower shaft section 4242. Specifically, a receiving chamber 4243 is provided at the lower end of the upper shaft section 4241. The first elastic member is provided in the receiving chamber 4243. The upper end of the lower shaft section 4242 extends into the receiving chamber 4243 and abuts against the first elastic member. A waist-shaped hole is provided on the side wall of the receiving chamber 4243. A connecting hole corresponding to the waist-shaped hole is provided at the upper end of the lower shaft section 4242. A rotation limiting pin is also provided. The rotation limiting pin passes through the waist-shaped hole and is inserted into the connecting hole to limit the relative rotation between the upper shaft section 4241 and the lower shaft section 4242.

[0041] When the upper mold A41 descends and the upper end of the torsion spring extends into the first groove of the upper mold A41, the elastic member is compressed, and when the first protrusion of the upper mold A41 is aligned with the snap-in at the upper end of the torsion spring, the elastic member releases and stretches, so that the first protrusion falls and snaps into the snap-in at the upper end of the torsion spring. Similarly, when the snap-in at the lower end of the torsion spring is aligned with the rotation-limiting snap-in 2111 of the lower mold 211, the elastic member releases and stretches, so that the snap-in at the lower end of the torsion spring snaps into the rotation-limiting snap-in 2111 of the lower mold 211.

[0042] Please refer to Figure 3 , Figure 7 and Figure 8 The twisting driving device 52 includes a second lifting driving member 521, a second lifting plate 522, a second rotating driving member 523 and a second rotating shaft 524. The second lifting driving member 521 drives the second lifting plate 522 to rise and fall, the second rotating driving member 523 is disposed on the second lifting plate 522, the second rotating driving member 523 drives the second rotating shaft 524 to rotate, and the upper mold B51 is disposed on the second rotating shaft 524.

[0043] The torsion mechanism 50 further includes a holding assembly 53, which includes an ejector pin 531 and an ejector cylinder 532. A through slot 2113 is formed on one side of the second groove 2112, and the ejector pin 531 is pushed by the ejector cylinder 532 to extend from the through slot 2113 and abut against the torsion spring.

[0044] When the rotary drive device 22 drives the sub-turntable 21 to rotate, the lower mold 211 is sent to the torsion mechanism 50 through the correction mechanism 40, and the second lifting drive member 521 drives the second lifting plate 522 to descend, and the second rotary drive member 523, the second rotary axis 524 and the upper mold B51 provided on the second lifting plate 522 follow and descend, so that the upper end of the torsion spring extends into the first groove of the upper mold B51. At this time, due to the correction, the position of the bayonet at the upper and lower ends of the torsion spring is fixed, so the bayonet at the upper end of the torsion spring is directly snapped into the first protrusion. The second rotating drive member 523 drives the second rotating shaft 524 and the upper mold B51 to rotate. At this time, the upper mold B51 rotates while the lower mold 211 does not move, so that the torsion spring is twisted. After twisting to a preset angle, the holding cylinder 532 pushes the ejector pin 531 to extend from the through-slit 2113 and abut against the torsion spring. The upper mold B51 is separated from the lower mold 211, and the torsion spring is retained in the lower mold 211 by the action of the ejector pin 531 to facilitate subsequent sorting processing of the torsion spring.

[0045] A second elastic member (not shown in the figure) is provided at the connection between the main shaft of the second rotating drive member 523 and the second rotating shaft 524, and the second elastic member is used to elastically connect the main shaft of the second rotating drive member 523 and the second rotating shaft 524.
