A collecting box 12 is placed correspondingly below each feeding mechanism 11. The feeding mechanism 7 includes a support frame 701, and a vibration plate 702 is fixedly installed on the upper end of the support frame 701. The discharge port of the vibration plate 702 is connected to each other through a guide pipe 703 and a connecting block 704. A supporting block 705 is arranged below the connecting block 704, and a first cylinder 706 is fixedly installed on the upper end of the supporting block 705. A feeding block 707 is fixedly connected to the telescopic end of the first cylinder 706, and a docking groove 708 is provided on the feeding block 707. A baffle plate 709 is fixedly installed, and the baffle plate 709 is located on the side of the indexing plate body 4, the upper end of the feeding block 707 and the lower end of the connecting block 704 are fitted with each other, and the feeding block 707 can slide on the supporting block 705, the baffle plate 709 is arranged in an arc structure, and the arc structure of the baffle plate 709 is the same as the center of the indexing plate body 4, the lower bending mechanism 8 includes a second cylinder 801, and the telescopic end of the second cylinder 801 is installed with a first pin 802, the first pin 802 is installed at the lower end of the vertical plate 803, and the upper end of the vertical plate 803 is installed with a second pin 804, the second pin 804 and the first pin 802 are both arranged in the retreat opening 805 opened on the vertical plate 803, and the second pin 804 is fixed to the end of the bending push rod 806, The bending push rod 806 is installed above the limiting bracket 807, and the middle part of the bending push rod 806 is installed on the horizontal base plate 808 through a rotating shaft. The horizontal base plate 808 is fixed on the limiting bracket 807, and a material guide step 809 is fixedly installed at one end of the limiting bracket 807 close to the dividing plate body 4. The outer walls of the second pin shaft 804 and the first pin shaft 802 are both in contact with the inner wall of the retreat opening 805, and the retreat opening 805 is set as a waist-shaped structure, and the second pin shaft 804 and the first pin shaft 802 can slide in the retreat opening 805. The upper ends of the bending push rod 806 and the limiting bracket 807 are slidably connected, and the material guide step 809 fixed at one end of the limiting bracket 807 close to the dividing plate body 4 is set as an arc structure cocentric with the dividing plate body 4.The upper bending mechanism 9 includes a third cylinder 901, and a movable platform 902 is fixedly installed at the telescopic end of the third cylinder 901, a bending roller 903 is rotatably connected to the movable platform 902, and a ring-shaped bending groove 904 is opened in the middle of the bending roller 903, and the limit bracket 101 includes a limit bracket 101, and the limit bracket 101 is fixed at the upper end of the control box 2, and a limit top block 102 is fixedly installed on one side of the limit bracket 101 close to the upper bending mechanism 9.

[0029] When the material is to be bent, the wires are uniformly placed inside the vibration plate 702. Under the action of the vibration plate 702, the wires can be shaken into the inside of the connecting block 704 through the guide tube 703. The inside of the connecting block 704 enters the docking groove 708 on the feeding block 707. At this time, the first cylinder 706 is turned on to make the feeding block 707 move toward the direction of the indexing plate body 4. When the docking groove 708 and the loading groove 6 on the indexing plate body 4 are located in the same vertical straight line, the wires fall into the loading groove 6. The setting of the baffle plate 709 can block the wires to prevent the wires from falling in the loading groove 6, thereby realizing automatic loading of the wires to be bent. Then, the servo drive module 5 controls the indexing plate body 4 to rotate, so that the wires inside the circumferential loading groove 6 of the indexing plate body 4 move between the upper bending mechanism 9 and the lower bending mechanism 8, and the second cylinder 801 is turned on. A pin shaft 802 moves in the retreat opening 805 below the vertical plate 803, thereby allowing the vertical plate 803 to rotate around the horizontal base plate 808. After the horizontal base plate 808 rotates, it can push the bending push rod 806 to move in the direction of the guide step 809, and the moved bending push rod 806 is used to provide auxiliary support for the cable to be bent. Thereafter, the third cylinder 901 is turned on. After the third cylinder 901 is turned on, the movable table 902 and the bending roller 903 can move in a straight line above the bending push rod 806, and cooperate with the bending push rod 806 to bend the cable. After bending the cable, the upper bending mechanism 9 and the lower bending mechanism 8 are reset to wait for the next bending of the cable. Thereafter, the rotating indexing plate body 4 can drive the bent cable to rotate synchronously until the cable collides with the unloading mechanism 11, and the bent cable is pushed by the unloading mechanism 11, so that the bent cable falls uniformly into the collection box 12 for centralized collection.

[0030] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. The following technical contents are disclosed in this embodiment: the unloading mechanism 11 includes a main rod body 111, and the main rod body 111 is fixed on the fixed disk 3. The end of the main rod body 111 away from the center of the fixed disk 3 is rotatably connected with an adjusting baffle 112, and a guide slider 113 is installed in the sliding groove on the adjusting baffle 112. The side of the guide slider 113 is hingedly connected with a power rod 114, and the power rod 114 is slidably installed on the fixed disk 3. The power rod 114 is connected to the fixed disk 3 through an auxiliary spring 115, and a center screw 116 is installed at the end of the power rod 114 away from the guide slider 113. A first magnetic block 117 is fixedly installed on the center screw 116, and a second magnetic block 118 is arranged on the side of the first magnetic block 117. The second magnetic block 118 is fixed on the dividing disk body 4, and the magnetic properties of the first magnetic block 117 and the second magnetic block 118 are opposite.

[0031] When the upper bending mechanism 9 and the lower bending mechanism 8 cooperate with each other to bend the cable, the dividing plate body 4 can drive the cable to rotate synchronously. After the cable contacts the adjusting baffle 112 during the rotation, the adjusting baffle 112 can be used to push the cable so that it can fall into the collection box 12. When the dividing plate body 4 rotates, the second magnetic block 118 on it can rotate synchronously. When the second magnetic block 118 rotates, it contacts the first magnetic block 117 at the end of the power rod 114. When the second magnetic block 118 moves away from the first magnetic block 117 at the end of the power rod 114 as the indexing plate body 4 rotates, the power rod 114 is reset and rebounded under the action of the auxiliary spring 115, thereby realizing the reciprocating movement of the power rod 114. After the reciprocating movement of the power rod 114, the hinged guide slider 113 can slide on the adjusting baffle 112, and the adjusting baffle 112 can be adjusted. The main rod body 111 is reciprocatingly rotated to adjust, and the contact point with the cable arrangement can be changed by adjusting the rotation of the baffle 112, so that the baffle 112 can be adjusted to push the cable down at different positions, so that the cable arrangement can fall at different positions and enter the collection box 12 with a larger width and a smaller height, so that the cable arrangement can be evenly distributed in the collection box 12, to avoid the cable arrangement falling position being fixed and stacked in one place inside the collection box 12. When a collection box 12 with a smaller width and a higher height is used to collect the cable arrangement, the center screw 116 is rotated. After the center screw 116 is rotated, the first magnetic block 117 can be moved toward the direction of the power rod 114. At this time, the first magnetic block 117 is far away from the second magnetic block 118, and they will not move under the action of the magnetic force. After the power rod 114 does not move, the baffle 112 will not rotate. Therefore, in the subsequent pushing, the cable arrangement The falling position is fixed, which can meet the collection box 12 with a smaller width and a higher height.

[0032] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
