[0002] In automated wire harness processing equipment, the wire feeding mechanism is a key component for achieving efficient wire transmission and precise positioning. In existing technologies, such as the "Wire Harness Dual-Head Simultaneous End-Cut and Insertion Device" disclosed in patent number CN 223167839 U, the wire feeding mechanism employs multiple linearly arranged wire feeding clamps. A wire feeding longitudinal movement device drives these clamps to move back and forth, thereby achieving continuous wire harness feeding.

[0003] However, the multiple sets of cable clamps are arranged in a linear manner. Although this design can achieve synchronous processing of multiple wire harnesses, the overall length of the mechanism increases significantly when the number of clamps increases, resulting in excessive space occupied by the equipment and reducing its applicability.

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 A wire feeding mechanism for a wire harness termination and insertion device, see below. Figures 1-6 It includes a mounting bracket 100, a wire cutting assembly 200, a turntable 300, a connector 400, and a first wire clamp 500.

[0021] The wire cutting assembly 200 is fixedly connected to the top surface of the mounting bracket 100. It employs a conventional structure and includes two cutters capable of cutting the wire. A turntable 300 is fixedly connected to one side of the mounting bracket 100 and is a conventional, hollow, electrically operated rotary table. A connecting seat 400 is fixedly connected to the turntable 300 and can rotate under the drive of the turntable 300. Multiple first wire clamps 500 are disposed on the connecting seat 400 and are used to clamp the wire. Multiple first wire clamps 500 are arranged circumferentially.

[0022] When using this mechanism, each first wire clamp 500 passes through one wire, and then the wire is clamped by its respective first wire clamp 500. The multiple wires passing through the first wire clamps 500 can be wires of different specifications and colors. After threading, only one wire is used for processing; the wire used for processing is simply called the working wire, and the corresponding first wire clamp 500 is called the working wire clamp. The working wire clamp is rotated using the turntable 300 to be positioned opposite the wire cutting assembly 200, and then the end of the working wire is extended through the wire cutting assembly 200 so that the wire pulling mechanism of the wire harness end-cutting and inserting device can pull out the wire for subsequent automated processing. When it is necessary to change to other wires for processing, the original working wire is pulled back so that it does not extend beyond the wire cutting assembly 200. The turntable 300 is rotated until the corresponding wire, first wire clamp 500, and wire cutting assembly 200 are aligned, and then the wire is pulled out and extended through the wire cutting assembly 200.

[0023] The above-described wire feeding mechanism arranges multiple first wire clamps 500 along the circumferential direction on the turntable 300. This arrangement is shorter than the traditional linear arrangement, thus reducing the length of the mechanism, minimizing the space occupied by the mechanism and equipment, and improving the applicability of the equipment. The turntable 300 can not only rotate the first wire clamps 500 to face the wire cutting assembly 200 to achieve the wire cutting function, but also rotate the first wire clamps 500 to a position convenient for maintenance.

[0024] In this embodiment, the connecting base 400 includes a connecting disc 410, a connecting cylinder 420, and a threading disc 430. The connecting disc 410 is vertically arranged and one end face is fixedly connected to the turntable 300. One end of the connecting cylinder 420 is fixedly connected to the other end of the connecting disc 410, and the threading disc 430 is fixedly connected to the other end of the connecting cylinder 420, forming a structure similar to an H-shaped reel. The threading disc 430 is a disc with multiple threading holes 431 evenly spaced along its edge in the circumferential direction. The multiple threading holes 431 are correspondingly arranged with multiple first wire clamps 500. The wire passes through the threading hole 431 and then through the corresponding first wire clamp 500.

[0025] The connecting disc 410 is also a disc, and it is coaxially arranged with the connecting cylinder 420, the threading disc 430, and the turntable 300. The projection of the connecting disc 410 toward the threading disc 430 is within the range of the lines connecting the multiple threading holes 431. The threading channel 512 of the first wire clamp 500 is in the same radial region as the corresponding threading hole 431. Thus, after the wire passes through the threading hole 431 and the first wire clamp 500, it extends directly to the area between the connecting disc 410 and the wire cutting assembly 200.

[0026] To facilitate identification of the wires passing through the wire holes 431, the end face of the wire reel 430 away from the connecting cylinder 420 is marked with a label 432, such as a number, at the position corresponding to each wire hole 431. In this way, the wires can be identified by recognizing the number.

[0027] Furthermore, a connecting plate 410 is also provided at the other end of the connecting cylinder 420, and the threading plate 430 is fixedly connected to the connecting plate 410. This way, if the threading hole 431 of the threading plate 430 is not suitable after changing the wire size, the threading plate 430 with a different size threading hole 431 can be replaced.

[0028] In this embodiment, multiple square connecting strips 433 are fixed between the two connecting discs 410 of the connecting seat 400. The multiple connecting strips 433 are evenly spaced along the circumference, and the two ends of the connecting strips are respectively fixedly connected to the edge positions of the two connecting discs. The structure and connection method of each first wire clamp 500 are the same, and one of them will be described below. The first wire clamp 500 includes a connecting block 510, a wire clamping block 520, and a first elastic member 530. The connecting block 510 is Z-shaped and slides on the connecting strip 433 through the square sliding hole 511 at the bottom, and can move along the connecting strip 433. The top of the connecting block 510 is provided with a wire passage 512 and a mounting through hole 513. The wire passage 512 passes through both ends of the connecting block 510, and the mounting through hole 513 intersects with the wire passage 512. Specifically, the mounting through hole 513 passes through the connecting block 510 vertically and intersects the wire passage 512 perpendicularly, thereby dividing the wire passage 512 into two segments. The top of the mounting through hole 513 is radially expanded to form a mounting groove 514. The wire clamping block 520 includes a sliding shaft 521, which is slidably connected within the mounting through hole 513. The bottom of the sliding shaft 521 is provided with a first limiting part 5212, which is in limiting engagement with the top bottom surface of the connecting block 510. The top of the sliding shaft 521 is provided with a second limiting part 5213, which extends out of the mounting groove 514 and engages with the top surface of the connecting block 510. The second limiting part 5213 is preferably a bolt threaded onto the top of the sliding shaft 521. The sliding shaft 521 is provided with a wire through hole 5211 that engages with the wire threading channel 512. The first elastic member 530 is preferably a spring, which is sleeved on the sliding shaft 521 and located within the mounting groove 514. One end of the first elastic member 530 abuts against the bottom surface of the mounting groove 514, and the other end abuts against the second limiting part 5213. Under normal conditions, the sliding shaft 521 moves upward under the action of the first elastic element 530, causing the wire through hole 5211 to be offset upward from the wire channel 512, thereby clamping the wire. When the second limiting part 5213 is pressed down until it contacts the top surface of the connecting block 510, the wire through hole 5211 and the wire channel 512 are coaxially aligned, releasing the clamping of the wire, and the wire can be pulled out.

[0029] The wire threading channel 512 is arranged along the axial direction of the turntable 300, and the mounting through hole 513 is arranged along the radial direction of the turntable 300.

[0030] Furthermore, a groove 515 is formed radially outward at the bottom of the mounting through hole 513. The second limiting part 5213 is slidably disposed within the groove 515, and the top surface of the second limiting part 5213 becomes the wire pressing surface. Under the action of the first elastic member 530, the wire pressing surface of the second limiting part 5213 presses down on the wire, which can greatly alleviate the problem of wire scratches or even damage.

[0031] In this embodiment, the mechanism further includes a mounting frame 610, a first driving device 620, and an unlocking component 630. The mounting frame 610 is fixedly installed. The first driving device 620 can be a telescopic cylinder, which is fixed to the top of the mounting frame 610, with its telescopic rod inclined downwards. The unlocking component 630 is a push rod, i.e., a rod structure, with one end fixed to the output end of the first driving device 620 and the other end engaging with the working wire clamp. When it is necessary to release the clamping of the wire, the first driving device 620 drives the unlocking component 630 to press down the second limiting part 5213 of the wire clamping block 520.

[0032] In this embodiment, the clamping block 520 and the unlocking member 630 are offset from each other along the axial direction of the turntable 300. To allow the clamping block 520 to move relative to the unlocking member 630 and release the clamp on the wire, the mechanism further includes a second driving device 700. The second driving device 700 cooperates with the connecting block 510 to drive the connecting block 510 to move. After the wire is pulled out, to move the connecting block 510 to its initial position, a second elastic member 434, preferably a spring, is provided on the connecting strip 433. Its two ends abut against the connecting disc 410 and the connecting block 510 near the turntable 300, respectively, to push the connecting block 510 to its initial position.

[0033] Preferably, the connecting block 510 is provided with a transmission rod 540. One end of the transmission rod 540 is fixedly connected to the connecting block 510, and the other end of the transmission rod 540 passes through the connecting plate 410 and the threading plate 430 away from the turntable 300 and extends out of the threading plate 430. The second driving device is a telescopic bar, which is in a pushing engagement with the transmission rod 540 and can push the transmission rod 540 to move the connecting block 510. When the connecting block 510 is reset, the pushing device 800 no longer pushes the transmission rod 540, and the connecting block 510 is reset under the action of the second elastic member 434.

[0034] In this embodiment, the turntable 300 is a hollow turntable, and the connecting cylinder 420 of the connecting seat 400 is a hollow structure that runs through both ends. A connecting rod 110 can be fixed on the mounting bracket 100. The connecting rod 110 extends out of the turntable 300 and the connecting seat 400, and then extends out of the connecting seat 400. The second driving device 700 is fixed on the connecting rod 110.

[0035] Example 2 A terminal insert device, see Figure 7 It includes a wire feeding mechanism, a wire pulling mechanism (not shown in the figure), a wire feeding mechanism 910, and two sets of processing units arranged symmetrically on the left and right. The wire pulling mechanism is arranged on the left and right to pull out the wire from the wire feeding mechanism, and the wire feeding mechanism 910 is arranged front and back to transport the pulled-out and cut wire to the two sets of processing units, which then process both ends of the wire. Except for the wire feeding mechanism, which adopts the wire feeding mechanism of Embodiment 1, the other mechanisms can adopt existing mechanisms.

[0036] In this embodiment, the processing unit includes a terminal cutting mechanism 920 and a shell insertion mechanism 930, which are used to terminal cut and insert shells into the wire.

[0037] Furthermore, if heat shrink tubing is to be fitted onto the wire, a tubing fitting mechanism 940, a tubing baking mechanism 950, and a stripping mechanism 960 can be sequentially installed between the wire inlet mechanism and the end-cutting mechanism 920. The heat shrink tubing is fitted onto the wire through the tubing fitting mechanism 940, and the heat shrink tubing is fixed onto the wire through the tubing fitting mechanism 940.

[0038] The above-mentioned end-cutting mechanism 920, shell insertion mechanism 930, sleeve mechanism 940, tube baking mechanism 950, and peeling mechanism 960 adopt existing mechanisms, and will not be described in detail.

[0039] The above description is only a preferred embodiment of the present utility model, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
