Sliding seat five 706 is slidably connected with the front side of "7"-shaped seat two 704, and sliding seat five 706 is fixedly connected to the wire trimming mounting seat 708 through L-shaped seat 707. The ground wire cutting mechanism 70 uses cylinder seven 703 to push the wire cutting mounting seat 708 forward, so that the pneumatic clamping claw 709 and the wire cutting assembly on it move to just above the ground wire, and then uses cylinder eight 705 to push the wire cutting mounting seat 708 downward, and the pneumatic clamping claw 709 clamps the upper end of the ground wire. Cylinder eight 705 then slightly drives the wire cutting mounting seat 708 to move upward, so that the pneumatic clamping claw 709 clamps and straightens the ground wire. At this time, the bidirectional cylinder of the wire cutting assembly moves, driving the two knife arms 711 to open and close, thereby driving the wire cutting knife 712 to open and close to cut the ground wire.

[0050] like Figure 11As shown, the ground wire pressing mechanism 80 is located above the fourth operating station and is used to press the ground wire from front to back against the iron casing of the data cable, facilitating subsequent welding.

The sliding seat seven 806 is slidably connected to the front side of the "7"-shaped seat three 804. The front side of the sliding seat seven 806 is fixed with a push plate 807. The ground wire pressing mechanism 80 uses cylinder nine 803 to drive the sliding seat six 802 forward, so that the pushing plate 807 moves to the front and upper part of the ground wire, and then drives the sliding seat seven 806 downward through cylinder ten 805. Cylinder nine 803 then drives the sliding seat six 802 backward, so that the pushing plate 807 presses the ground wire on the iron shell of the data cable.

[0051] like Figure 12As shown, the ground wire welding mechanism 90 includes a rotating component 2 902 and a welding component 904. The rotating component 2 902 is arranged at the rear side of the fifth operating station. The rotating component 2 902 is used to drive the rotating seat 1 304 to rotate so that the data line rotates one circle during welding. In this embodiment, the rotating component 2 902 includes a cylinder 11 9024, a motor base 2 9021, a motor 3 9022 and a rotating base 3 9023. The cylinder 11 9024 is horizontally fixed on the support frame 6 901. The telescopic end of the cylinder 11 9024 is connected to the motor base 2 9021. The bottom surface of the motor base 2 9021 is slidably connected to the top surface of the support frame 6 901. The motor 3 9022 is fixed to the top surface of the motor base 2 9021. The output shaft of the motor 3 9022 is connected to the rotating base 3 9023. The rotating base 3 9023 is provided with an "I"-shaped groove 2 9025 that cooperates with the protrusion 309 on the rotating base 1 304. The welding assembly 904 is arranged above the fifth workstation. The welding assembly 904 includes a soldering iron 9047, a tin wire, and a displacement mechanism five for pushing the soldering iron and the tin wire to move back and forth up and down. The displacement mechanism five is also provided with a tin feeding control assembly 906 for controlling the feeding of the tin wire. The displacement mechanism five is connected to a fixed seat 9044, and the fixed seat 9044 is connected to a soldering iron seat 9045 and a strip tin wire seat 9046. The soldering iron 9047 is vertically fixed in the fixing hole of the soldering iron seat 9045, and the lower end of the strip tin wire seat 9046 is provided with a tin wire hole for horizontally passing the tin wire. The displacement mechanism five includes a cylinder twelve 9042 and a sliding seat eight 9043. The support frame seven 903 is fixed on the "7"-shaped seat four 9041. The cylinder twelve 9042 is vertically fixed on the top of the "7"-shaped seat four 9041, and its telescopic end is connected to the sliding seat eight 9043. The sliding seat eight 9043 is slidably connected with the "7"-shaped seat four 9041. The top surface of the sliding seat eight 9043 is connected to the fixed seat 9044 and the soldering iron seat 9045 in sequence, and the strip tin wire seat 9046 is fixed on the side of the sliding seat two 603. During welding, cylinder 11 9024 moves first, pushing motor base 2 9021 forward, so that the "I"-shaped groove 2 9025 of rotating base 3 9023 is plugged into the protrusion 309 of rotating base 1 304, and cylinder 12 9042 and cylinder 13 9052 move synchronously, driving the soldering iron 9047 and tin wire to move downward to the ground wire welding position synchronously. At the same time, cylinder 3 of the opening and closing control component 312 moves, pushing the tapered pin 3122 to move, pass through the through hole 310 and insert into the groove 311, controlling the clamping block 306 to open slightly, and then motor 3 9022 drives rotating base 3 9023 to rotate, driving rotating base 1 304 to rotate synchronously, completing one circle of ground wire welding.

[0052] like Figure 13As shown, the displacement mechanism five is also provided with a tin feeding control component 906 for controlling the feeding of the tin wire. The tin feeding control component 906 includes a meshing driving gear 9062, a driven gear 9063 and a motor four 9065 for driving the driving gear 9062 to rotate. A tin feeding mounting bracket 9061 is provided on one side of the sliding seat eight 9043. The driving gear 9062 and the driven gear 9063 are arranged on the top surface of the tin feeding mounting bracket 9061. The motor four 9065 is arranged on the bottom surface of the tin feeding mounting bracket 9061. The middle parts of the driving gear 9062 and the driven gear 9063 are respectively provided with semi-arc shaped annular grooves 9064. The two semi-arc shaped annular grooves 9064 form a gap for the tin wire to pass through. The tin feeding mounting bracket 9061 is also provided with a turntable 9066 for placing the tin wire roll. The turntable 9066 is rotatably connected to the tin feeding mounting bracket 9061, and a central shaft 9067 is fixed to the top of the turntable 9066. During use, the tin wire passes through the gap between the annular grooves 9064 and then through the tin wire hole of the strip tin wire holder 9046. The motor 609 drives the driving gear 9062, which in turn drives the driven gear 9063, thereby moving the tin wire clamped in the gap into the tin. Since the tin wire becomes shorter after soldering, the tin feeding control component 906 pushes the tin into the solder, ensuring the next soldering.

[0053] like Figure 12 As shown, since the tin wire is relatively soft and prone to positional displacement, in order to position and fix the tin wire during the welding process, a tin wire positioning device 905 is provided on the support frame 7 903 below the welding assembly 904. The tin wire positioning device 905 includes a positioning tube, a positioning tube frame 9054, and a displacement mechanism 6 that pushes the positioning tube frame 9054 up and down. The positioning tube frame 9054 is arranged horizontally, and the end of the positioning tube frame 9054 is provided with a tube hole for the positioning tube to pass horizontally. In this embodiment, the displacement mechanism 6 includes a cylinder 13 9052 and a push plate 9053. A tin feed positioning mounting frame 9051 is fixed on the support frame 7 903. The cylinder 13 9052 is fixed to the tin feed positioning mounting frame 9051. The telescopic end of the cylinder 13 9052 is connected to the push plate 9053. The side of the push plate 9053 passes through the vertical strip hole located on the side of the tin feed positioning mounting frame 9051 and is connected to the positioning tube frame 9054. During welding, the positioning tube is fixed on the tube hole of the positioning tube rack 9054. Under the action of the cylinder thirteen 9052, the positioning tube rack 9054 is pushed down to position the tin wire. The position of the tin wire is positioned by the positioning tube to prevent the tin wire from shifting.

[0054] The working principle of the present invention is

[0055] Step 1: Clamp the data cable with the workpiece clamping mechanism 30 and place the workpiece clamping mechanism 30 at the end of the slideway 101;

[0056] Step 2: The pushing mechanism 20 is activated, and the cylinder 202 pushes the pushing plate 203 outward, pushing the workpiece clamping mechanism 30 into the first operating station;

[0057] Step 3: Rotate the ground wire. Cylinder 502 moves first, pushing motor base 1 504 forward, so that the "I"-shaped groove 1 507 of rotating base 2 506 is plugged into the protrusion 309 of rotating base 1 304. At this time, cylinder 3 of the opening and closing control component 312 moves, pushing the tapered latch 3122 to move, passing through the through hole 310 and inserting into the groove 311, controlling the clamp to open slightly. Then motor 1 505 drives rotating base 2 506 to rotate, thereby driving rotating base 1 304 to rotate, and thus driving the data cable to rotate. During the rotation process, CCD recognition component 501 recognizes the position of the ground wire and rotates the ground wire to the specified position so that each ground wire is in the same position.

[0058] Step 4: The displacement mechanism 1 40 is activated to move the workpiece clamping mechanism 30 on the first operating station to the second operating station.

[0059] Step 5: To adjust the ground wire, the screw drive mechanism 602 is used to drive the sliding seat 2 603 to move forward, so that the ground wire brush 608 moves to the front of the ground wire. Then, the cylinder 605 is used to push the sliding seat 3 606 downward, driving the ground wire brush 608 downward. Then, the screw drive mechanism 602 drives the sliding seat 2 603 to move backward. At the same time, the motor 2 609 drives the ground wire brush 608 to rotate, so that the ground wire is adjusted to a vertical state.

[0060] Step 6: The displacement mechanism 1 40 is activated to move the workpiece clamping mechanism 30 on the second operating station to the third operating station.

[0061] Step 7: Cut the ground wire. Cylinder 703 pushes the wire trimmer mounting seat 708 forward, so that the pneumatic clamping claw 709 and the wire trimmer assembly on it move to just above the ground wire. Cylinder 8 705 then pushes the wire trimmer mounting seat 708 downward, and the pneumatic clamping claw 709 clamps the upper end of the ground wire. Cylinder 8 705 then slightly drives the wire trimmer mounting seat 708 upward, so that the pneumatic clamping claw 709 clamps and straightens the ground wire. At this time, the bidirectional cylinder of the wire trimmer assembly moves, driving the two knife arms 711 to open and close, thereby driving the wire cutter 712 to open and close to cut the ground wire.

[0062] Step 8: The displacement mechanism 1 40 is activated to move the workpiece clamping mechanism 30 on the third operating station to the fourth operating station.

[0063] Step 9: Press the ground wire. Cylinder 9 803 drives the sliding seat 6 802 forward, so that the push plate 807 moves to the front of the ground wire. Cylinder 10 805 then drives the sliding seat 7 806 downward. Cylinder 9 803 then drives the sliding seat 6 802 backward, so that the push plate 807 presses the ground wire against the iron shell of the data cable.

[0064] Step 10: The displacement mechanism 1 40 is activated to move the workpiece clamping mechanism 30 on the fourth operating station to the fifth operating station.

[0065] Step 11: Welding the ground wire, cylinder 11 9024 moves first, pushing motor base 2 9021 forward, so that the "I"-shaped groove 2 9025 of rotating base 3 9023 is plugged into the protrusion 309 of rotating base 1 304, cylinder 12 9042 and cylinder 13 9052 move synchronously, driving the soldering iron 9047, tin wire, and positioning tube to move synchronously downward to the ground wire welding position. At this time, cylinder 3 3123 of the opening and closing control component 312 moves, pushing the tapered pin 3122 to move, passing through the through hole 310 and inserting into the groove 311, controlling the clamping block 306 to open slightly, and then motor 3 9022 drives rotating base 3 9023 to rotate, driving rotating base 1 304 to rotate synchronously, completing one circle of ground wire welding.

[0066] While the present invention has been generally described above, modifications and improvements are readily apparent to those skilled in the art. Therefore, modifications and improvements that do not depart from the spirit of the present invention are intended to be within the scope of the present invention.
