[0036] In one embodiment of the present invention, please refer to Figure 1 The wire piercing and crimping device is used for crimping a piercing type connector female socket. Specifically, the wire piercing and crimping device includes a wire clamping fixture 100, a crimping mechanism 200, a positioning mechanism 300, a horizontal pushing mechanism 400, and a connector female socket conveying mechanism 500.

[0037] Reference Figure 10 The wire clamping fixture 100 is provided with a plurality of clamping grooves 101 for clamping the wires corresponding to the wire array, so that the wires of the wire array can be equidistant from each other or spaced at a certain distance.

[0038] Reference Figure 2 、 Figure 3 and Figure 6The crimping mechanism 200 includes a support base 210, a downward pressing drive 220, a piercing and pushing member 230, and a positioning base 240. The support base 210 is mounted on a frame 10. A mounting position 211 is provided on the top side of the support base 210. The downward pressing drive 220 is mounted on the mounting position 211. The piercing and pushing member 230 is mounted on the downward pressing drive 220. A plurality of extrusion heads 231 are arranged at the bottom end of the piercing and pushing member 230 for squeezing the piercing terminals of the connector female socket. The positioning base 240 is located at the bottom end of the piercing and pushing member. A support step 241 is provided on the front side of the positioning base 240 for supporting the connector female socket.

[0039] Reference Figure 2 、 Figure 4 and Figure 5 The positioning mechanism 300 is located in front of the crimping mechanism 200 and is used to position and support the wire clamping jig 100. The horizontal push mechanism 400 is connected to the positioning seat 240 or the positioning mechanism 300 and is used to drive the positioning seat 240 or the positioning mechanism 300 to move, so that the positioning seat 240 and the wire clamping jig 100 move closer to or farther from each other. The connector socket conveying mechanism 500 is located on one side of the positioning seat 240 and is used to push the connector socket onto the support step 241.

[0040] The connector socket conveying mechanism 500 can be a vibrating conveying device or a belt conveying mechanism. When crimping the wire row and the connector socket, the ends of the wires of the wire row are arranged in sequence in the clamping groove 101 of the wire clamping fixture 100, and the connector socket is conveyed to the support step 241 of the positioning seat 240 by the connector socket conveying mechanism 500. The positioning seat 240 or the positioning mechanism 300 is then driven by the horizontal push mechanism 400 to move horizontally, so that the free end of the wire on the positioning fixture 100 is inserted into the connector socket; the downward pressing driving member 220 drives the piercing and pushing member 230 to move downward, so that the extrusion head 231 on the bottom side of the piercing and pushing member 230 squeezes the terminal in the connector socket, so that the terminal in the connector socket is pressed down to pierce the wire and riveted to fix it. Therefore, the wire row is inserted into the connector socket at one time, and the wire row is pierced at one time; thus, the efficiency of wire row crimping is improved.

[0041] Furthermore, a card slot is provided on the front side of the positioning seat 240 for limiting the position of the connector female seat. Specifically, when the connector female seat conveying mechanism 500 conveys the connector female seat to the support step 241, the card slot limits the top side of the connector female seat.

[0042] Further, refer to Figure 4 and Figure 5The positioning seat 240 includes a seat body 242, a cover plate 243 and a spring 244. The front end of the seat body 242 is provided with a support step 241 and an upwardly extending mounting portion 245. The cover plate 243 is pivotally connected to the mounting portion 245 and forms a rotation fulcrum for the cover plate 243. One end of the cover plate 243 extends above the support step 241 and forms a slot with the support step 241. The spring 244 is provided between the seat body 242 and the cover plate 243 and is used to support the cover plate 243 upward so that the end of the cover plate 243 and the support step 241 clamp the connector female socket. A pressing mechanism 250 is also provided on one side of the support seat 210 for pressing down the cover plate 243 so that the cover plate 243 overcomes the elastic force of the spring 244 and opens. In this embodiment, when the connector base is transported to the positioning seat 240, the pressing mechanism 250 can push one end of the cover plate 243 downward to overcome the elastic force of the spring 244, so that the slot is opened, thereby facilitating the insertion of the connector base into the slot. After the connector base is positioned on the support step 241, the pressing mechanism 250 retracts upward, and the spring 244 elastically supports the cover plate 243, causing the slot end of the cover plate 243 to swing downward, thereby clamping the connector base, thereby facilitating the insertion of the wire into the connector base and facilitating the crimping of the connector base and the wire.

[0043] Furthermore, refer to Figure 4 and Figure 5 A limiting mechanism 260 is also provided on one side of the support seat 210 for limiting one end of the cover plate 243 so that the bottom side of the cover plate 243 is parallel to the support step 241. Specifically, in this embodiment, when the connector socket conveying mechanism 500 pushes the connector socket onto the positioning seat 240, the limiting mechanism 260 pushes the cover plate 243 so that the card slot end of the cover plate 243 remains slightly open, so that the connector socket can be smoothly pushed into the card slot, and the connector socket can be limited by the card slot and withdrawn from the card slot. The pressing mechanism 250 pushes the card slot end of the cover plate 243 to release the connector socket after the line row and the connector socket are crimped, so as to facilitate its removal.

[0044] Specifically, the limiting mechanism 260 includes a lifting drive 261 and a pressure plate 262. The lifting drive 261 is located on one side of the support base 210. The pressure plate 262 is connected to the lifting drive 261 and extends above the pivot point of the cover plate 243. Specifically, when the lifting drive 261 pushes the pressure plate 262 downward, the bottom surface of the pressure plate 262 contacts the top surface of the cover plate 243, causing the slot end of the cover plate 243 to be slightly tilted. The lifting drive 261 is a pneumatic or electric cylinder.

[0045] Going further, refer to Figure 2The horizontal push mechanism 400 is connected to the positioning seat 240 and is used to drive the positioning seat 240 to move, so that the positioning seat 240 moves alternately between the output end of the connector female socket conveying mechanism 500 and the bottom end of the piercing and pushing member 230. When the positioning seat 240 moves to the bottom end of the piercing and pushing member 230, the wire can be inserted into the connector female socket.

[0046] Further, refer to Figure 2 and Figure 3 The crimping mechanism 200 further includes a lower pressing block 270, which is connected to the lower pressing drive member 220. A plurality of protrusions 271 are provided at the bottom end of the lower pressing block 270 for retaining the wires within the clamping groove 101. Specifically, during the crimping process, the protrusions 271 at the bottom end of the lower pressing block 270 press on the wires in the clamping groove 101, thereby securing and retaining the wires, preventing the wires from loosening during the crimping process and ensuring the stability of the crimping.

[0047] Further, refer to Figure 2 、 Figure 3 、 Figure 7 and Figure 8 , the wire row piercing and crimping device also includes a wire pushing mechanism 600, which is used to clamp the end of the wire and push it into the connector female seat. Specifically, the wire pushing mechanism includes a vertical plate 610, a movable plate 620, a translation drive 630, a clamping drive 640, an upper clamping plate 650 and a lower clamping plate 660. The vertical plate 610 is arranged on one side of the support seat 210, specifically on the frame 10. The movable plate 620 is slidably arranged on one side of the vertical plate 610, and the translation drive 630 is connected to the movable plate 620. The clamping drive 640 is arranged on the top side of one end of the movable plate 620, the upper clamping plate 650 is connected to the clamping drive 640, the lower clamping plate 660 is arranged on the bottom side of one end of the movable plate 620, and the bottom side of the upper clamping plate 650 is provided with a plurality of open grooves 651. The top side of the lower clamping plate 660 is further provided with a positioning slot 661, and the bottom side of the lower clamping plate 650 is further provided with a limiting plate 652. When the upper clamping plate 650 and the lower clamping plate 660 clamp the wire, the limiting plate 652 is positioned within the positioning slot 661. Both the clamping drive 640 and the translation drive 630 are translation cylinders. In this embodiment, the clamping drive 640 drives the upper clamping plate 650 downward, positioning each wire within its corresponding opening slot 651. The wire is then detected by the lower clamping plate 660. The translation drive 630 then moves the plate, causing the upper and lower clamping plates 650 and 660 to move and extend the clamped wires into the connector socket.

[0048] Further, refer to Figure 2 and Figure 3 The downward pressing driving member 220 includes a cylinder 221 and a slide 222; the cylinder 221 is provided on the mounting position 211, the slide 222 is provided on one side of the support base 210, and the cylinder 221 is connected to the slide 222.

[0049] Furthermore, a lifting cylinder 223 is provided on the slide 222, and the pressing block 270 is connected to the lifting cylinder 223. The lifting cylinder 223 drives the pressing block 270 to descend and press the wire into the clamping groove 101.

[0050] Further, refer to Figure 1 The positioning mechanism 300 is located on the stepping conveyor line on one side of the crimping mechanism 200. A punching mechanism 700 is also located along the conveying direction of the stepping conveyor line to punch out the ribs on the side of the connector socket. Specifically, in this embodiment, after the connector is crimped onto the end of the line, the unnecessary ribs on the side of the connector can be removed according to the requirements of subsequent connector connections, thereby ensuring the connection requirements of subsequent connectors.

[0051] Specifically, refer to Figure 9 The punching mechanism 700 includes a mounting base 710, a punching knife 720 and a punching drive assembly 730. The punching drive assembly 730 is provided with a cylinder on the mounting base 710. The punching knife 720 is connected to the punching drive assembly 730.
