[0031] The limiting mechanism is installed in the placing space and used for limiting the wire in the placing space from sliding outward, the limiting mechanism is provided with two, and the two limiting mechanisms are respectively located on the two sides of the moving groove 502, the limiting mechanism comprises a limiting column 8 movably inserted into the top of the placing plate 501, a spring clamping block 20 fixed to the bottom of the limiting column 8, and a buffer spring 19 movably sleeved on the outer periphery of the limiting column 8, the spring clamping block 20 is located below the placing plate 501, the top of the buffer spring 19 is fixed to the bottom surface of the placing plate 501, the bottom of the buffer spring 19 is fixed to the spring clamping block 20, and the top of the limiting column 8 is in a semispherical structure, in the initial state, the elastic force of the buffer spring 19 can lift the spring clamping block 20 upward, so that the top of the limiting column 8 is higher than the top surface of the placing plate 501, thereby limiting and blocking the wire bundle in the placing space, preventing the wire bundle from sliding outward before the placing disc rotates or is arranged, and the semispherical structure of the top of the limiting column 8 can reduce the frictional resistance between the pressing plate 204 and the limiting column 8 when the pressing plate 204 passes through the limiting column 8, and also enables the pressing plate 204 to smoothly press down the limiting column 8, avoiding the movement of the pressing plate 204 being hindered by the limiting column 8.

[0032] The force applying mechanism 2 is used for applying force on the wire in the placing space in the forming position, pushing the wire into the forming space, and making the wire bend from the middle and form a U-shaped structure. The force applying mechanism 2 comprises a top plate 201 installed on the forming position, a pressing plate 204 installed on the bottom surface of the top plate 201, a pushing column 205 fixed on the bottom surface of the pressing plate 204, and a driving assembly installed on the top plate 201 and used for driving the pressing plate 204 to move along the radial direction of the placing disc 3.

The driving assembly comprises a transmission screw 202 rotatably connected in the sliding groove 203 and a sliding block 206 threadedly sleeved on the outer periphery of the transmission screw 202. The two side outer walls of the sliding block 206 are respectively slidably abutted with the two side long inner walls of the sliding groove 203, so as to avoid the shaking of the sliding block 206 when the transmission screw 202 rotates. One end of the top plate 201 is provided with a transmission motor used for driving the transmission screw 202 to rotate. The transmission motor is a servo motor with a model of 40ST-M00330. The bottom of the sliding block 206 is fixedly connected with the top surface of the pressing plate 204. When the feeding mechanism rotates to the forming position, the arrangement of the wire bundle is completed. At this time, the transmission motor is started to drive the transmission screw 202 to rotate forward, and then the sliding block 206 drives the pressing plate 204 and the pushing column 205 to move to the side away from the center of the placing disc 3. The pushing column 205 enters the moving groove 502. After the pushing column 205 contacts with the wire bundle, the wire bundle is pushed to enter the forming space. The wire bundle enters the horizontal section after being guided by the inclined section to complete the U-shaped bending. After the wire bundle completely enters the horizontal section, the transmission motor is stopped to rotate forward. Then the transmission motor is started to rotate reversely to drive the pressing plate 204 and the pushing column 205 to return to the original position, waiting for the bending of the wire bundle in the next feeding mechanism. Finally, the placing disc 3 rotates the feeding mechanism 5 in the forming position to the discharging position, and the worker takes out the formed U-shaped wire bundle to be bundled, completing a processing cycle.

The bottom surface height of the pressing plate 204 is lower than the top portion height of the limiting column 8. The top surface of the pressing plate 204 is located above the top portion of the limiting column 8. The bottom surface height of the pressing plate 204 is lower than the top portion height of the limiting column 8, so that the bottom surface of the pressing plate 204 can press the top surface of the wire bundle when the wire bundle is pushed by the pushing column 205, avoiding the wire bundle from bouncing upward. The end of the pressing plate is provided with a right-angled triangular structure, which facilitates the pressing plate to automatically press down the limiting column 8 when passing through the limiting column 8, avoiding the limiting column 8 from blocking the movement of the pressing plate 204.

[0035] Embodiment 3 In combination Figure 5 Figure 6 ​The further improvement of the embodiment is that the bottom surface of the placing plate 501 is provided with knocking mechanisms which cooperate with the adjusting assembly to knock the placing plate 501 to make it vibrate when the size of the placing space is adjusted. The knocking mechanisms are provided in two groups and are arranged on the two sides of the moving groove 502. The knocking mechanism comprises a rotating wheel 14 sleeved on the outside of the bidirectional screw rod 11, a swing arm 15 arranged on the bottom surface of the placing plate 501, an accommodating plate 18 hingedly connected to the bottom of the end of the swing arm 15 close to the rotating wheel 14, and a resetting member arranged on the bottom surface of the placing plate 501 and used to drive the swing arm 15 to automatically reset after rotation. The bottom of one end of the accommodating plate 18 is hingedly connected to the bottom of one end of the swing arm 15, so that the accommodating plate 18 can rotate downward around the hinge as the center and abut against the end of the swing arm 15 when rotating upward, so as not to rotate upward relative to the swing arm 15. The swing arm 15 is arranged obliquely, and the end of the swing arm 15 away from the bottom surface of the placing plate 501 is fixedly provided with a rubber ball 16. The outer periphery of the rotating wheel 14 is fixedly provided with a plurality of pushing pieces 21 arranged in the radial direction. The pushing pieces 21 cooperate with the accommodating plate 18 and push the accommodating plate 18 to rotate towards the bottom surface of the placing plate 501 when the rotating wheel 14 rotates forward, so as to drive the rubber ball 16 to move away from the placing plate 501. The top surface of the accommodating plate 18 and the swing arm 15 are provided with elastic members used to drive the accommodating plate 18 to automatically restore to the original position after bending. When the pushing pieces 21 are out of contact with the accommodating plate 18, the rubber ball 16 will automatically knock the bottom surface of the placing plate 501 under the driving of the resetting member to make the placing plate 501 vibrate. The resetting member comprises two mounting blocks 17 fixedly arranged on the bottom surface of the placing plate 501 and rotating shafts 24 rotatably connected to the outer walls of the two mounting blocks 17 on the sides close to each other. The other ends of the two rotating shafts 24 are fixedly connected to the outer walls of the two sides of the swing arm 15. The outer periphery of the rotating shaft 24 is provided with a torsional spring 23 used to drive the rotating shaft 24 to automatically reset after rotation. When the adjusting assembly drives the bidirectional screw rod 11 to rotate forward, the rotating wheel 14 rotates forward synchronously, and the pushing pieces 21 on the outer periphery of the rotating wheel 14 rotate synchronously. When the pushing pieces 21 contact the accommodating plate 18, the accommodating plate 18 is pushed upward. Since the bottom of the accommodating plate 18 is hingedly connected to the bottom of the swing arm 15, when the accommodating plate 18 is pushed upward, the top of one end of the accommodating plate 18 abuts against the end of the swing arm 15, so as to drive the end of the swing arm 15 to synchronously swing upward. At this time, the rubber ball 16 swings downward and moves away from the bottom surface of the placing plate 501. The torsional spring 23 is compressed synchronously. When the pushing pieces 21 rotate past the accommodating plate 18, the torsional spring 23 restores the deformation, drives the rotating shaft 24 and the swing arm 15 to quickly reset, and the rubber ball 16 quickly knocks the bottom surface of the placing plate 501, so that the placing plate 501 vibrates. The vibration is transmitted to the wire bundle in the placing space, so that the wire bundle quickly adjusts the posture under the action of the vibration, realizes alignment of the two ends, and improves the arrangement effect.

[0036] The elastic member comprises a limiting plate 22 fixed on the top surface of the swing arm 15 near one end of the rotating wheel 14 and a connecting spring 25 installed on the bottom surface of the limiting plate 22, and the top surface of the receiving plate 18 is provided with a receiving groove 26 for receiving the connecting spring 25, and the other end of the connecting spring 25 is fixedly connected with the bottom surface of the receiving groove 26. When the rotating wheel 14 is reversed, the push piece 21 pushes the receiving plate 18 to rotate downward, and the connecting spring 25 is stretched. When the push piece 21 is separated from the receiving plate 18, the connecting spring 25 restores the deformation, thereby driving the receiving plate 18 to automatically rotate upward to restore the original position. At the same time, the bottom surface of the limiting plate 22 abuts against the top surface of the receiving plate 18 in the normal state, thereby further limiting the upward rotation of the receiving plate 18 relative to the swing arm 15.

[0037] The above-described embodiments are merely preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and replacements made by those skilled in the art based on the present application shall fall within the scope of protection of the present application.
