Description

Technical Field

[0001] The invention relates to the technical field of wiring harness terminal plugging, in particular to an automobile wiring harness terminal plugging tool. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Its main function is to connect the various electrical devices of the car so that the current can be transmitted between the various components, thereby ensuring the normal operation of the automotive electrical system. In order to facilitate the connection between the automotive wiring harness and various electrical components, it is necessary to plug terminals on the wiring harness.

[0003] When the terminals of the wire harness are plugged in, it is usually completed using a plug-in tool, which is matched with a mold. The terminal is placed between the two molds, and then the staff plugs the wire harness into the mold through the mold, and plugs the terminal into the wire harness with the mold.

[0004] When performing terminal connection for a wiring harness composed of multiple strands of wire, after the insulation layer of the wiring harness is removed, the multiple strands of wire will be loose due to the lack of the insulation layer. When performing terminal connection, reverse wire phenomenon often occurs, that is, part of the wire does not enter the terminal. In this case, the external reverse wire may cause the wiring harness to short-circuit. Usually, when performing wiring harness terminal connection, it is mostly batch operation, and the terminal connection is performed through a mold. The terminal and the wiring harness need to be accurately aligned during the connection work, resulting in low connection efficiency. When performing batch connection work, it will affect the overall processing efficiency. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0037] like Figure 1 and Figure 2As shown, an automotive wiring harness terminal plug-in tool comprises a mounting frame 1, the inner bottom end of the mounting frame 1 is provided with two front-to-back symmetrical connecting sleeves 2 for multi-station splicing, and the mounting frame 1 is provided with a positioning mechanism 5 for clamping the wiring harness, a limiting mechanism 4 for limiting the exposed wires of the wiring harness, a clamping mechanism 3 for squeezing the terminal, a terminal placing mechanism 7 for placing the terminal and a gathering mechanism 6 for tightening the exposed wires of the wiring harness from back to front.

[0038] like Figure 1 and Figure 3 As shown, the alignment mechanism 5 includes two left-right symmetrical moving rails 51 fixedly connected to the mounting frame 1, and a first electric slider 52 is slidably connected to the moving rail 51 along the front-to-back direction. The opposite back surfaces of the two first electric sliders 52 are provided with a first linkage sleeve 53 for multi-station splicing, and the upper surfaces of the two first electric sliders 52 are jointly provided with an alignment piece 54.

[0039] like Figure 3 As shown, the positioning member 54 includes a supporting cross plate 541 to which the upper surfaces of the two first electric sliders 52 are commonly fixedly connected, and two front-to-back symmetrical bidirectional elastic telescopic rods 546 are fixedly connected to the lower surface of the supporting cross plate 541, and a fixed connecting frame 542 is fixedly connected to the telescopic end of the bidirectional elastic telescopic rod 546, and an auxiliary plate 543 is commonly fixedly connected to the two fixed connecting frames 542 distributed front and back, and the auxiliary plate 543 is slidably matched with the supporting cross plate 541, and two upper and lower symmetrical connecting slides 545 are fixedly connected to the opposite surfaces of the two auxiliary plates 543, and a limited extrusion plate 544 is elastically slidably connected to the two connecting slides 545 arranged upper and lower along the front-to-back direction.

[0040] During specific use, the staff first places the position of the wiring harness with the insulation layer between the two limiting extrusion plates 544 and presses it downward. At this time, the two limiting extrusion plates 544 are subjected to a force in the direction of moving away from each other, and the limiting extrusion plates 544 push the auxiliary plates 543 to move synchronously. The auxiliary plates 543 drive the telescopic section of the two-way elastic telescopic rod 546 to move through the fixed connecting frame 542, and cooperate with the elastic force of the two two-way elastic telescopic rods 546 themselves to generate a reverse force on the auxiliary plates 543, thereby clamping the wiring harness between the two limiting extrusion plates 544, while ensuring that one end of the exposed wire of the wiring harness is located on the limiting mechanism 4, and then the wiring harness is driven forward on the moving track 51 by the first electric slider 52. When the front side of the insulation layer of the wiring harness contacts the limiting mechanism 4, the movement of the first electric slider 52 is stopped, and the placement of the wiring harness is completed.

[0041] It should be noted that when multiple tools are required to work at the same time, a fixing rod can be inserted between the connecting sleeves 2 on the two tools, and the fixing rod and the connecting sleeve 2 can be limited by a limiting bolt to ensure that the two tools are relatively fixed. At the same time, a linkage rod is inserted inside the first linkage sleeve 53 to make the supporting cross plates 541 between the multiple tools move synchronously. When aligning the wiring harnesses on the multiple tools, the wiring harnesses placed on the multiple tools are uneven, and multiple supporting cross plates 541 move forward synchronously for a distance. At this time, the insulation layer of some wiring harnesses will contact the limiting mechanism 4, while some wiring harnesses will not contact the limiting mechanism 4. As the cross plate 541 continues to move, the wiring harness that abuts against the limiting mechanism 4 will generate resistance to the cross plate 541. At this time, as the cross plate 541 continues to move, the resistance acts on the limiting extrusion plate 544, pushing the limiting extrusion plate 544 to slide backward on the connecting slide bar 545. At this time, when multiple cross plates 541 continue to move synchronously, the wiring harness that abuts against the limiting mechanism 4 will not hinder the movement of the cross plate 541. Then, the cross plate 541 can continue to push the wiring harness that does not abut against the limiting mechanism 4 to move forward until the insulation layers of all the wiring harnesses abut against the limiting mechanism 4. At this time, the alignment of all the wiring harnesses is completed.

[0042] like Figure 1 and Figure 4 As shown, the limiting mechanism 4 includes a support plate 42 fixedly connected to the upper surface of the mounting frame 1 , a limiting member 41 is provided on the upper surface of the support plate 42 , and a pressing member 43 is provided on both the limiting member 41 and the support plate 42 .

[0043] like Figure 4 and Figure 5 As shown, the limiting member 41 includes two left-right symmetrical fixing seats 411 fixedly connected to the upper surface of the support plate 42, and two front-to-back symmetrical first elastic telescopic rods 412 are fixedly connected to the opposite surfaces of the two fixing seats 411. The two first elastic telescopic rods 412 distributed front and back are commonly fixedly connected to one end away from the fixing seat 411 with an arc-shaped extrusion block 413, and the arc-shaped extrusion block 413 is slidably matched with the support plate 42.

[0044] like Figure 4 and Figure 5 As shown, the clamping member 43 includes two left-right symmetrical second electric telescopic rods 436 fixedly connected to the mounting frame 1 and located below the support plate 42, the bottom ends of the two second electric telescopic rods 436 are commonly fixedly connected with a third linkage sleeve 435, a U-shaped pushing frame 432 is fixedly connected to the middle of the upper surface of the third linkage sleeve 435, and two left-right symmetrical sliding plates 434 are slidably connected to the support plate 42 along the left-right direction, and a limiting block 433 is fixedly connected to the upper surface of the sliding plate 434.

[0045] like Figure 4 and Figure 5 As shown, the two limit blocks 433 correspond one-to-one with the two arc-surface extrusion blocks 413 and slide together. The front sides of the two arc-surface extrusion blocks 413 are provided with grooves adapted to the terminals. The limit blocks 433 and their corresponding fixed seats 411 are elastically slidably connected. The opposite back surfaces of the two sliding plates 434 are both inclined and correspond one-to-one with the two vertical sections of the U-shaped push frame 432. Auxiliary rollers are provided at the tops of the two vertical sections of the U-shaped push frame 432. The left and right ends of the third linkage sleeve 435 are provided with linkage ports for multi-station splicing.

[0046] During specific use, when the staff places the wiring harness on the alignment member 54, the exposed wire portion of the wiring harness is located between the two arc-surface extrusion blocks 413. The two arc-surface extrusion blocks 413 cooperate with the elastic force of the first elastic telescopic rod 412 to limit the exposed wire. At the same time, the front end of the insulation layer of the wiring harness contacts the rear surface of the support plate 42. At this time, the secondary limiting work before tightening and gathering the exposed wire of the wiring harness begins. The third linkage sleeve 435 moves upward by contracting the second electric telescopic rod 436, and the third linkage sleeve 435 pushes the U-shaped push rod 436. The frame 432 moves upward synchronously. At this time, the two vertical sections of the U-shaped push frame 432 slide upward against the inclined surface of the sliding plate 434. With the help of the auxiliary rollers on the vertical sections of the U-shaped push frame 432, the sliding between the U-shaped push frame 432 and the sliding plate 434 can be smoother. The U-shaped push frame 432 continues to move upward, pushing the two sliding plates 434 on the support plate 42 to move towards each other, driving the two limit blocks 433 to move synchronously to perform secondary clamping and limiting on the exposed wire part of the wiring harness located between the two arc-surface extrusion blocks 413.

[0047] It should be noted that, after multiple toolings are spliced, a linkage rod is inserted between opposite surfaces of the third linkage sleeves 435 on two toolings, so that the third linkage sleeves 435 on the multiple toolings move synchronously.

[0048] like Figure 1 and Figure 6 As shown, the gathering mechanism 6 includes two left-right symmetrical displacement rails 64 fixedly connected to the upper surface of the mounting frame 1, a driving member 63 is commonly provided on the front sides of the two displacement rails 64, a displacement member 62 is commonly provided on the rear sides of the two displacement rails 64, a gathering member 65 is provided on the rear side of the displacement member 62, and an adjusting member 61 is provided on the gathering member 65.

[0049] During specific use, after completing the secondary clamping and limiting of the exposed wires of the wiring harness, the displacement member 62 moves backward on the displacement track 64, pushing the gathering member 65 to move to the front side of the arc extrusion block 413, and then the gathering member 65 is pushed to clamp on the exposed wires of the wiring harness through the adjustment member 61. At this time, the displacement member 62 moves forward, and during the movement, the driving member 63 drives the gathering member 65 to rotate, so as to tighten and gather the exposed wires of the wiring harness.

[0050] like Figure 6 , Figure 7 and Figure 8 As shown, the gathering member 65 includes a connecting cross brace 652 fixedly connected to the displacement member 62, and two left-right symmetrical L-shaped mounting plates 653 are fixedly connected to the rear side of the upper surface of the connecting cross brace 652, and an arc-shaped extrusion plate 651 is elastically hinged on the vertical section of the L-shaped mounting plate 653.

[0051] like Figure 6 and Figure 7 As shown, the adjusting member 61 includes a mounting sleeve 612 fixedly connected to the lower surface of the horizontal section of the L-shaped mounting plate 653, an adjusting rod 613 is slidably connected to the upper surface of the mounting sleeve 612, an auxiliary roller is provided at the top of the adjusting rod 613, the auxiliary roller and its corresponding arc-shaped extrusion plate 651 are rollingly matched, a sliding track 614 is fixedly connected to the rear end of the lower surface of the connecting cross brace 652, a second electric slider 611 is slidably connected to the sliding track 614 along the up and down directions, the left and right sides of the second electric slider 611 are fixedly connected with synchronization plates 615, and the end of the synchronization plate 615 away from the second electric slider 611 is fixedly connected to the bottom end of the corresponding adjusting rod 613.

[0052] During specific use, when the gathering piece 65 is pushed to clamp on the exposed wire through the adjusting piece 61, the second electric slider 611 moves upward on the sliding track 614, and drives the adjusting rod 613 to move upward on the mounting sleeve 612 through the synchronization plate 615. At this time, the auxiliary roller at the top of the adjusting rod 613 slides upward against the outer arc surface of the arc extrusion plate 651, pushing the arc extrusion plate 651 to rotate on the L-shaped mounting plate 653 toward the exposed wire of the wiring harness until the arc extrusion plate 651 is tightly attached to the exposed wire of the wiring harness, and then the second electric slider 611 remains stationary, and the arc extrusion plate 651 is limited by the adjusting rod 613.

[0053] like Figure 6 , Figure 7 and Fig. 9As shown, the driving member 63 includes a connecting sleeve 631 which is slidably connected to the displacement track 64 along the front-to-back direction, the lower surfaces of the two connecting sleeves 631 are commonly fixedly connected with a mounting cross brace, the rear surface of the mounting cross brace is fixedly installed with a driving motor, the lower surface of the mounting cross brace is fixedly connected with a linkage box 633, the left and right sides of the linkage box 633 are rotatably connected with synchronous spline sleeves 632, the end of the synchronous spline sleeve 632 close to the linkage box 633 penetrates into the interior of the linkage box 633, the rear surface of the linkage box 633 is rotatably connected with a connecting shaft 634, the front end of the connecting shaft 634 penetrates into the front surface of the linkage box 633 and is fixedly connected to the output shaft of the driving motor, the circumferential surface of the connecting shaft 634 located inside the linkage box 633 is connected to the synchronous spline sleeve 632 through a bevel gear transmission, and the rear end of the connecting shaft 634 is rotatably connected with a transmission gear 635.

[0054] like Figure 6 , Figure 7 and Figure 8 As shown, the displacement member 62 includes a third electric slider 623 slidably connected to the displacement track 64 along the front-to-back direction, and the fourth linkage sleeve 624 is fixedly connected to the opposite back surfaces of the two third electric sliders 623. The two third electric sliders 623 are commonly fixedly connected to a positioning frame 622, and the internal rotation of the positioning frame 622 is connected to a gear plate 621. The rear surface of the positioning frame 622 is provided with a through hole smaller than the diameter of the gear plate 621, and the lower surface of the positioning frame 622 is provided with a through groove adapted to the transmission gear 635. The transmission gear 635 passes through the through groove and meshes with the gear plate 621, and the connecting cross brace 652 passes through the through groove on the positioning frame 622 and is fixedly connected to the front surface of the gear plate 621.

[0055] During specific use, when the two arc-shaped extrusion plates 651 are clamped on the exposed wires of the wiring harness, the driving motor drives the transmission gear 635 to rotate through the connecting shaft 634, and the transmission gear 635 drives the toothed disc 621 to rotate inside the positioning frame 622. The toothed disc 621 drives the two arc-shaped extrusion plates 651 to rotate synchronously through the connecting cross brace 652. At this time, the exposed wires of the wiring harness are tightened and gathered by the rotation of the two arc-shaped extrusion plates 651. At the same time, the third electric slider 623 slides forward on the displacement track 64 to tighten and gather the exposed wires of the wiring harness from back to front, and the connecting sleeve 631 moves synchronously with the third electric slider 623.

[0056] It should be noted that when the driving motor drives the connecting shaft 634 to rotate, the connecting shaft 634 is driven by a bevel gear (such as Fig. 9As shown), the two synchronous spline sleeves 632 on the linkage box 633 are driven to rotate synchronously. When multiple toolings are spliced, the spline shafts are inserted between the opposite surfaces of the synchronous spline sleeves 632 on the two toolings, so that the synchronous spline sleeves 632 on the multiple toolings rotate synchronously, thereby making the multiple transmission gears 635 rotate synchronously, and the linkage rod is inserted between the opposite surfaces of the fourth linkage sleeves 624 on the two toolings, so that the positioning frames 622 on the multiple toolings move synchronously.

[0057] like Figure 1 and Figure 6 As shown, the terminal placement mechanism 7 includes two left-right symmetrical first electric telescopic rods 72 fixedly connected to the upper surface of the mounting frame 1, an auxiliary telescopic rod 71 is fixedly connected to the upper surface of the mounting frame 1 and located in front of the first electric telescopic rod 72, the auxiliary telescopic rods 71 ​​distributed front and back and the top of the first electric telescopic rod 72 are commonly fixedly connected to a synchronous connecting frame 73, a terminal placement box 74 is fixedly connected between the opposite surfaces of the two synchronous connecting frames 73, the bottom ends of the left and right sides of the terminal placement box 74 are fixedly connected with L-shaped limit plates 75, the front side of the L-shaped limit plate 75 is provided with a groove compatible with the arc extrusion plate 651, and the opposite back surfaces of the two synchronous connecting frames 73 are provided with second linkage sleeves 76 for linking the synchronous connecting frames 73 on multiple tooling.

[0058] During specific use, as the third electric slider 623 continues to move, when the arc-shaped extrusion plate 651 is separated from the exposed wire of the cable, the driving motor continues to rotate, driving the two arc-shaped extrusion plates 651 to continue to rotate and adjust their positions until the contact point of the two arc-shaped extrusion plates 651 away from one end of the L-shaped mounting plate 653 is in a position just above, and then the first electric telescopic rod 72 begins to contract, driving the terminal placement box 74 to move downward, and the setting of the auxiliary telescopic rod 71 can make the terminal placement box 74 move more smoothly during movement. When the terminal placement box 74 moves to the specified position, After the terminal box 74 is in the correct position, the first electric telescopic rod 72 stops contracting and keeps the terminal placement box 74 stationary. Then the second electric telescopic rod 436 extends, driving the U-shaped push frame 432 to move downward. At this time, the U-shaped push frame 432 moves downward along the inclined surface of the sliding plate 434, and the thrust exerted on the sliding plate 434 gradually decreases. Since the limit block 433 and the fixed seat 411 are elastically slidably connected, the limit block 433 is driven to move toward the fixed seat 411 under the action of the elastic force between the limit block 433 and the fixed seat 411, thereby releasing the limit block 433 from clamping the exposed wires of the wiring harness.

[0059] Then the third electric slider 623 moves backward on the displacement track 64. When the arc extrusion plate 651 moves to the position of the L-shaped limit plate 75, in conjunction with the groove set on the L-shaped limit plate 75, the two arc extrusion plates 651 enter between the two L-shaped limit plates 75 and push the terminals between the two L-shaped limit plates 75 to move backward. In conjunction with the exposed wires that have been tightened and gathered, the terminals can be smoothly plugged into the exposed wires of the wiring harness. The arc extrusion plate 651 continues to push the terminals to move backward. In conjunction with the grooves on the two arc surface extrusion blocks 413, the terminals can smoothly enter between the two arc surface extrusion blocks 413 until the rear end of the terminal is attached to the insulating layer of the wiring harness. Then, the terminal is stopped from being pushed to move, and then the terminal is pressed on the wiring harness through the clamping mechanism 3.

[0060] It should be noted that after the terminal between the two L-shaped limiting plates 75 is pushed away, the terminal inside the terminal placement box 74 moves downward under the action of its own gravity, so that a terminal is loaded between the two L-shaped limiting plates 75 again, and the lower side of the outer circumferential surface of the terminal is limited by the horizontal sections of the two L-shaped limiting plates 75 (such as Fig.10 As shown), at the same time, the first electric telescopic rod 72 extends through the synchronous connecting frame 73 to push the terminal placement box 74 to move upward to the original position. After multiple toolings are spliced, the linkage rod is inserted between the opposite surfaces of the second linkage sleeves 76 on two toolings, so that the second linkage sleeves 76 on multiple toolings move synchronously.

[0061] like Figure 1 and Figure 4 As shown, the clamping mechanism 3 includes a bidirectional electric telescopic rod 31 fixedly connected to the bottom end of the inner side of the mounting frame 1, and sickle-shaped connecting rods 32 are fixedly connected to the left and right telescopic ends of the bidirectional electric telescopic rod 31, and clamping blocks 33 are fixedly connected to the opposite surfaces of the horizontal sections of the two sickle-shaped connecting rods 32.

[0062] During specific use, after the terminal is plugged into the exposed wire of the wiring harness, the bidirectional electric telescopic rod 31 contracts in both directions, and drives the two clamping blocks 33 to move towards each other through the sickle-shaped connecting rod 32, clamping the terminal on the exposed wire of the wiring harness. At this time, the wiring harness terminal plug-in work is completed, and then the bidirectional electric telescopic rod 31 is extended to restore the two clamping blocks 33 to their original positions. At this time, the first electric slider 52 moves backward on the moving track 51 to drive the wiring harness to move backward synchronously. At this time, the two arc-surface extrusion blocks 413 generate extrusion force on the terminal plugged in the wiring harness, and cooperate with the first electric slider 52 to drive the wiring harness to move backward, so as to check whether the terminal is firmly crimped.

[0063] Then the wiring harness is removed from the supporting cross plate 541, and the first electric slider 52 continues to move backward to restore the supporting cross plate 541 to its original position. Since the limiting extrusion plate 544 and the connecting slide rod 545 are elastically slidably connected, the limiting extrusion plate 544 is restored to its original position under the action of elastic force. At the same time, the second electric slider 611 moves downward on the sliding rail 614, driving the adjusting rod 613 to move downward synchronously and restore to its original position. At this time, the adjusting rod 613 no longer generates thrust on the arc extrusion plate 651. Since the arc extrusion plate 651 and the L-shaped mounting plate 653 are elastically hinged, the two arc extrusion plates 651 are opened on their corresponding L-shaped mounting plates 653 under the action of elastic force. At this time, the third electric slider 623 continues to move backward to move the two arc extrusion plates 651 back to the front side of the arc surface extrusion block 413. Repeat the above steps to carry out the next wiring harness terminal plug-in work.

[0064] like Figure 1-Figure 10 As shown, the working principle is: during specific use, the staff first places the wiring harness on the alignment member 54, and at the same time places the exposed wire part of the wiring harness between the two limit members 41, and limits the exposed wire of the wiring harness through the limit member 41, and then aligns the position of the wiring harness through the alignment mechanism 5. At this time, the gathering member 65 cooperates with the displacement member 62 and the driving member 63 to tighten and gather the exposed wires of the wiring harness and gradually move forward. After the exposed wires of the wiring harness are gathered, the first electric telescopic rod 72 is contracted to drive the terminal placement box 74 to move downward to the specified position, and the displacement member 62 drives the gathering member 65 to move backward, and pushes the terminal inside the terminal placement box 74 backward to be mounted on the terminal of the wiring harness, and then the terminal is pressed onto the wiring harness through the clamping mechanism 3. At this time, the terminal plugging of a wiring harness is completed, and the wiring harness with completed terminal plugging is removed from the alignment mechanism 5, and the above steps are repeated for the next terminal crimping.
