DETAILED DESCRIPTION

[0029] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0030] like Figures 1 to 10As shown, the present invention provides a wire feeding mechanism, which includes a feeding fixed seat 81, a wire conveying track 82 arranged on the feeding fixed seat 81 and used for transferring wires from the outside, a transfer driving device 83 arranged on the feeding fixed seat 81 and used to drive the wires to move on the wire conveying track 82, a wire cutting device 84 arranged on one side of the feeding fixed seat 81 and located at the discharge end of the wire conveying track 82, and a wire moving manipulator 85 arranged on the side of the wire cutting device 84 away from the feeding fixed seat 81, the wire moving manipulator 85 is used to transfer one end of the wire output by the wire conveying track 82 to the external conveying device 01, and the wire cutting device 84 is located between the feeding fixed seat 81 and the wire moving manipulator 85. Specifically, the wire cutting device 84 and the wire moving manipulator 85 are respectively located on both sides of the external conveying device 01. The moving direction of the wire is perpendicular to the feeding direction of the conveying device 01.

[0031] In actual application, the wires output from the external wire coils are inserted into the wire conveying track 82. Driven by the transfer drive device 83, the wires move through the wire conveying track 82 and pass through the wire cutting device 84 and the external conveying device 01 in sequence until one end of the wire moves to the picking position of the wire transfer robot 85; then, the wire transfer robot 85 picks up the wire that has passed through the conveying device 01 and bends the wire section and then places it on the conveying device 01. This process can be referred to Figure 1 to Figure 2 As shown; then, the wire transfer manipulator 85 releases the wire pickup and resets, and the wire cutting device 84 cuts the wire output by the wire conveying track 82, so that both ends of the wire can be placed on the conveying device 01, so that the wire can be stably conveyed and processed. The structure of the present invention is simple and compact. With the cooperation of the transfer drive device 83, the wire conveying track 82, the wire cutting device 84 and the wire transfer manipulator 85, the wire can be automatically loaded. It has high automation and does not require manual operation, thereby reducing labor costs and improving wire loading efficiency. In addition, the present invention loads stably and accurately, effectively improving the processing quality of the wire.

[0032] In the present technical solution, the wire material moving manipulator 85 comprises a manipulator fixed seat 851 arranged on one side of the wire cutting device 84, a lifting block 852 slidably arranged on the manipulator fixed seat 851, a first lifting drive device 853 installed on the manipulator fixed seat 851 and used to drive the lifting block 852 to rise and fall, a rotating drive device 854 installed on the lifting block 852, and a wire clamping device 855 drivingly connected to the rotating drive device 854, wherein the wire clamping device 855 is used to clamp the wire outputted from the wire conveying track 82. Specifically, the first lifting drive device 853 is a driving cylinder; the rotating drive device 854 is a servo motor, and the wire clamping device 855 is eccentrically arranged with respect to the output shaft of the servo motor.

[0033] In actual application, the wire is driven by the transfer drive device 83, and the wire moves through the wire conveying track 82 and passes through the wire cutting device 84 and the conveying device 01 in sequence. At this time, the wire is transferred to the bottom of the wire clamping device 855; then, the first lifting drive device 853 drives the lifting block 852 to descend, and the descending lifting block 852 drives the rotating drive device 854 and the wire clamping device 855 to descend until the wire clamping device 855 contacts the wire and clamps the wire; after clamping the wire, the first lifting drive device 853 drives the lifting block 852 to rise, and then the rotating drive device 854 drives the lifting block 852 to rise. The driving device 854 drives the wire clamping device 855 to rotate, and the rotating wire clamping device 855 drives the wire to bend. The rotated wire clamping device 855 is located above the conveying device 01. The first lifting driving device 853 drives the lifting block 852 to descend again, so that the wire clamping device 855 places the clamped wire on the conveying device 01. Then the wire clamping device 855 is reset under the action of the first lifting driving device 853 and the rotating driving device 854, and the wire cutting device 84 cuts the wire, so that both ends of the wire can be placed on the conveying device 01. The structure design of the wire transfer manipulator 85 is simple and compact, the operation is stable and reliable, and the movement is accurate and fast.

[0034] In the present technical solution, the clamping device 855 includes a rotating block 8551, two clamping blocks 8552, and a first opening and closing driver 8553 for driving the two clamping blocks 8552 to close or unfold each other, one end of the rotating block 8551 is connected to the output end of the rotation drive device 854, and the other end of the rotating block 8551 is connected to the first opening and closing driver 8553. Specifically, the first opening and closing driver 8553 is a finger cylinder. The rotating block 8551 is in the shape of a long strip, which is used to make the rotation axis of the two clamping blocks 8552 not coincide with the output shaft of the rotation drive device 854 (i.e., the servo motor), thereby enabling the two clamping blocks 8552 to achieve eccentric rotation.

[0035] In actual application, the first opening and closing driver 8553 drives the two clamping blocks 8552 to close or expand each other to achieve clamping and releasing of the wire; the rotating driving device 854 drives one end of the rotating block 8551 to rotate, and the other end of the rotating block 8551 drives the first opening and closing driver 8553 to rotate eccentrically with the two clamping blocks 8552. The design of this structure allows the two clamping blocks 8552 to rotate above the conveying device 01, so that the end of the wire clamped by the clamping block 8552 can be placed on the side of the output end of the wire, so that both ends of the wire can be placed on the conveying device 01.

[0036] In the present technical solution, the two opposite side walls of the two wire clamping blocks 8552 are provided with protrusions 8554, and the protrusions 8554 are recessed from the outside to the inside to provide a wire clamping cavity 8555 for accommodating the power line. Specifically, there are multiple protrusions 8554, and the multiple protrusions 8554 are arranged at intervals along the length direction of the wire clamping block 8552; the multiple protrusions 8554 of one wire clamping block 8552 are staggered with the multiple protrusions 8554 of another wire clamping block 8552. When the two wire clamping blocks 8552 are closed, the wire clamping cavities 8555 of the multiple protrusions 8554 respectively arranged on the two wire clamping blocks 8552 are connected, and the cavity walls of the wire clamping cavities 8555 clamp the wires. The design of this structure can enable the wire clamping block 8552 to stably clamp the wire with a longer end, so that the two wire clamping blocks 8552 can stably and accurately bend and transfer the section of wire. Preferably, an avoidance cavity 8556 is provided at one end of the two clamping blocks 8552 away from the first opening and closing driver 8553, and the avoidance cavity 8556 is used to avoid the clamping member on the conveying device 01, thereby preventing the clamping block 8552 from interfering with the clamping member and affecting the placement of the wires.

[0037] In the present technical solution, the wire feeding mechanism further includes a tangent device 86 disposed on the feeding fixed seat 81, and the tangent device 86 is used to perform tangent processing on the wires transferred on the wire conveying track 82. In practical applications, since the wires are composed of two wire cores, the two wire cores at the processing end of the wires need to be separated before the wires are processed to facilitate the subsequent processing of the wires. Therefore, when the wires are transferred to a certain distance, the tangent device 86 performs tangent processing on a small section of the wires on the wire conveying track 82 (i.e., separates the two wire cores of the wires in this section).

[0038] In the present technical solution, the wire cutting device 86 comprises a lifting seat 861 arranged on the loading fixed seat 81, a second lifting driving device 862 installed on the loading fixed seat 81 and used to drive the lifting seat 861 to lift and lower, a wire cutting knife 863 rotatably arranged on the lifting seat 861 and located above the wire conveying track 82, and a rotating driving device 864 installed on the lifting seat 861 and used to drive the wire cutting knife 863 to rotate, and the top of the wire conveying track 82 is provided with a through groove 821 connected to the inner cavity of the track, and the position of the through groove 821 corresponds to the position of the wire cutting knife 863. Specifically, the second lifting driving device 862 is a driving cylinder; the rotating driving device 864 is a driving motor.

[0039] In actual application, when the electric wire is moved to a preset distance on the conveying track, the second lifting drive device 862 drives the lifting seat 861 to descend, and the descending lifting seat 861 drives the rotating drive device 864 and the wire cutter 863 to descend until the wire cutter 863 descends into the through groove 821 and contacts the electric wire. At this time, the rotating drive device 864 drives the wire cutter 863 to rotate, and the rotating wire cutter 863 cuts the part between the two wire cores of the electric wire so that the two wire cores are cut apart; when the electric wire continues to move to the preset distance, the second lifting drive device 862 drives the lifting seat 861 to rise, thereby driving the wire cutter 863 to rise and leave the through groove 821, so that the wire cutter 863 cancels cutting the electric wire.

[0040] In the technical solution, the transfer drive device 83 includes an upper roller 831 rotatably arranged on the loading fixed seat 81, a lower roller 832 rotatably arranged on the loading fixed seat 81, and a roller rotation drive mechanism 833 installed on the loading fixed seat 81 and used to drive the upper roller 831 and the lower roller 832 to rotate synchronously, and the upper roller 831 and the lower roller 832 respectively contact the upper side and the lower side of the wire conveyed by the wire conveying track 82. Specifically, the wire conveying track 82 is provided with an opening for exposing the wire at the position of the upper roller 831 and the lower roller 832, and the upper roller 831 and the lower roller 832 both contact the wire through the opening.

[0041] In actual application, the roller rotation driving mechanism 833 drives the upper roller 831 to rotate clockwise and drives the lower roller 832 to rotate counterclockwise, and the rotating upper roller 831 and lower roller 832 drive the wire to move in the wire conveying track 82.

[0042] Preferably, the roller rotation driving mechanism 833 includes a first rotating shaft 110 rotatably arranged on the feeding fixed seat 81, a first rotating wheel 114 arranged on the first rotating shaft 110, a second rotating shaft 111 rotatably arranged on the feeding fixed seat 81, a second rotating wheel 115 arranged on the second rotating shaft 111, a third rotating shaft 112 rotatably arranged on the feeding fixed seat 81, a third rotating wheel 116 and a fourth rotating wheel 117 arranged on the third rotating shaft 112, a fourth rotating shaft 113 rotatably arranged on the feeding fixed seat 81, and a fourth rotating wheel 114 arranged on the fourth rotating shaft 115. The fifth rotating wheel 118 and the sixth rotating wheel 119 of the rotating shaft 113, the first transmission belt 120 wound around the first rotating wheel 114 and the third rotating wheel 116, the second transmission belt 121 wound around the second rotating wheel 115 and the fifth rotating wheel 118, and the rotating shaft driving device installed on the loading fixed seat 81 and used to drive the third rotating shaft 112 to rotate, the fourth rotating wheel 117 is meshed with the sixth rotating wheel 119; one end of the first rotating shaft 110 is connected to the lower roller 832, and one end of the second rotating shaft 111 is connected to the upper roller 831. Specifically, the rotating shaft driving device is a driving motor. In actual application, the shaft driving device drives the third shaft 112 to rotate, the rotating third shaft 112 drives the fourth rotating wheel 117 to rotate, the rotation of the fourth rotating wheel 117 drives the sixth rotating wheel 119 to rotate, the rotating sixth rotating wheel 119 drives the fourth shaft 113 to rotate, the rotating fourth shaft 113 drives the fifth rotating wheel 118 to rotate, the rotating fifth rotating wheel 118 drives the second rotating wheel 115 to rotate together with the second shaft 111 via the second transmission belt 121, and the rotating second shaft 111 drives the lower roller 832 to rotate; the rotating third shaft 112 also synchronously drives the third rotating wheel 116 to rotate, the rotating third rotating wheel 116 drives the first rotating wheel 114 to rotate via the transmission belt, and the rotating first rotating wheel 114 drives the first shaft 110 to rotate together with the upper roller 831. The roller rotation drive mechanism 833 has a simple and compact structural design. With the cooperation of the drive motor, the rotating wheel and the transmission belt, one drive motor can synchronously drive the upper roller 831 and the lower roller 832 to rotate, thereby reducing the working energy consumption of the present invention and improving the synchronization and stability of the rotation of the two rollers, thereby making the movement of the wire more stable and reliable.

[0043] In the present technical solution, the wire cutting device 84 includes a wire cutting fixed seat 841 arranged on one side of the feeding fixed seat 81, an upper scissors 842 and a lower scissors 843 slidably arranged on the wire cutting fixed seat 841, and a scissors driving device for driving the upper scissors 842 and the lower scissors 843 to move closer to or away from each other. The wire conveying track 82 is connected to the wire cutting fixed seat 841 to form a wire outlet, and the upper scissors 842 and the lower scissors 843 are respectively located at the upper and lower ends of the wire outlet.

[0044] In actual application, when the transfer drive device 83 stops driving the wire, the scissor drive device drives the upper scissors 842 and the lower scissors 843 to move synchronously close to the wire outlet, and then cuts off one end of the wire at the wire outlet, so that the wire is located on the conveying device 01, and the other end of the cut wire is also transferred to the conveying device 01 by the wire transfer robot 85, and now the conveying device 01 can convey the section of wire.

[0045] Preferably, the scissor driving device comprises a left slider 844 and a right slider 845 respectively slidably arranged on both sides of the trimmer fixing seat 841, a linkage member 846 rotatably arranged on the trimmer fixing seat 841, and a third lifting driving device 847 for driving the left slider 844 or the right slider 845 to rise and fall, and the upper scissors 842 and the lower scissors 843 are both located between the left slider 844 and the right slider 845; one end of the left slider 844 is connected to the lower scissors 843, one end of the right slider 845 is connected to the upper scissors 842, and the two ends of the linkage member 846 are respectively connected to the left slider 844 and the right slider 845.
