Description

Technical Field

[0001] The invention relates to the technical field of wire material processing equipment, and in particular to a wire material positioning and plugging mechanism. Background Art

[0002] When processing finished wires with shells at the ends, terminals are first pressed on the ends of multiple strands of wires, and then the ends of the wires with terminals are inserted into the shells to fix the terminals in the shells. The shells are designed with multiple sockets for accommodating the terminals, so the wire ends need to be corrected and positioned when inserted into the sockets so that the terminals on the wires can be accurately inserted into the sockets.

Its structure includes a wire feeding mechanism, a terminal crimping mechanism, a loading mechanism and a plugging mechanism.

After the wire harness passes through the terminal crimping mechanism and the terminal is pressed on its end, it is transported to the station that cooperates with the plugging mechanism. The plugging mechanism clamps the shell on the loading mechanism and inserts it into the terminal at the end of the wire harness.

The wire feeding mechanism 7 is used to feed the wire and extend the wire into the positioning mechanism 2. The positioning mechanism 2 is used to position the wire and the terminal at the end of the wire. The feeding mechanism 3 is used to feed the shell, and the pushing mechanism 5 pushes the shell to the shell insertion mechanism 4; the shell insertion mechanism 4 inserts the shell into the end of the wire. The positioning mechanism 2 includes a first driving mechanism 21, a wire positioning fixture 22, a first positioning plate 23, a second driving mechanism 24, a terminal positioning fixture 25 and a second positioning plate 26. The first positioning plate 23 is fixed below the wire positioning fixture 22, and the first driving mechanism 21 drives the wire positioning fixture 22 to move up and down. The second positioning plate 26 is correspondingly arranged behind the wire positioning fixture 22. The terminal positioning fixture 25 is correspondingly arranged below the second positioning plate 26. The second driving mechanism 24 drives the terminal positioning fixture 25 and the second positioning plate 26 to clamp or move away from each other.

[0033] When the wire positioning and plug-in shell mechanism is working, the wire feeding mechanism 7 feeds out multiple strands of evenly arranged wires. After the wires are pressed against the terminals, the wire feeding mechanism 7 moves to the workstation that cooperates with the positioning mechanism 2. The wire feeding mechanism 7 drives the wires to extend between the wire positioning fixture 22 and the first positioning plate 23. The terminal at the end of the wire is located between the terminal positioning fixture 25 and the second positioning plate 26. The first driving mechanism 21 drives the wire positioning fixture 22 to move downward and clamp the first positioning plate 23 below it. The wire positioning fixture 22 positions the multiple strands of wire harness. The second driving mechanism 24 drives the terminal positioning fixture 25 and the second positioning plate 26 to clamp each other, and the terminal positioning fixture 25 positions the terminal at the end of the wire harness. Then, the plug-in shell mechanism 4 clamps the shell on the feeding mechanism 3 and inserts the shell into the end of the above-mentioned wire. The wire positioning and plug-in shell mechanism adds a positioning process for the wire and the terminal before plugging in the shell, so that the position of the wire and the terminal corresponds to the position of the shell when plugging in the shell, thereby improving the yield rate after plugging in the shell.

[0035] The working principle of the second driving mechanism 24 is as follows: when the piston rod of the first cylinder 242 is extended, it drives the first slider 244 to slide upward, and the terminal positioning fixture 25 moves upward. The first rack 247 on the first slider 244 drives the second rack 248 to move downward through the gear 246, the second slider 245 slides downward, and the second positioning plate 26 moves downward and is clamped with the terminal positioning fixture 25.

[0038] The limit plate 141 is used to adjust the downward movement stroke of the wire positioning fixture 22, and the working principle is as follows: when the piston rod of the third cylinder 11 is extended, it drives the inclined wedge block 121 to move forward through the third slider 12; the inclined wedge block 121 drives the fourth slider 14 to move upward through the bearing 142. The limit plate 141 on the fourth slider 14 moves upward, and when the fixture mounting seat 213 moves downward until the limit boss 2131 abuts against the limit plate 141, the fixture mounting seat 213 stops moving, thereby limiting the downward movement stroke of the wire positioning fixture 22.
