Description

Technical Field

[0001] This utility model relates to the field of terminal processing equipment technology, and in particular to a wire pulling tool for processing wire terminals. Background Technology

[0002] A terminal wire is an electronic connector consisting of a wire and terminals. A terminal is typically a piece of metal or a tubular structure used to attach to one or both ends of a wire, facilitating a reliable electrical connection to other circuit components. Terminal wires are widely used inside and outside various electronic devices to transmit signals, data, or power.

[0003] Existing cold-pressed terminals for terminal wires are generally manufactured using a terminal crimping machine. After wire feeding, bundling, stripping, and cutting, the terminal piece is directly riveted to the exposed wire core at the end of the wire and then cold-pressed. During processing, the cutting station and the cold-pressing station are not located together. After the wire is stripped and cut, it is transferred to the cold-pressing station by a movable clamping fixture. During processing, the wire core at the end of the wire should ideally be close to the upper surface of the terminal piece. In existing technology, the height of the wire is a certain distance above the terminal piece during transfer, mainly to prevent the wire from hitting the terminal piece during transfer. However, if the gap is too high, the wire will bend under pressure during crimping. Since the wire has been fixed beforehand, the end of the wire will also bend inward due to bending, preventing the terminal piece from completely covering the end wire core. Moreover, the difference in stress on the wire itself will lead to different degrees of bending, which in turn will lead to different inward displacements at the end, seriously affecting the yield rate and indicating room for further improvement. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a wire pulling tool for processing wire terminals, thereby solving the above-mentioned problem.

[0005] To achieve the above objectives, a wire-pulling fixture for processing wire terminals is provided, including a rotating disk, a toothed rail fixedly connected to the upper center of the rotating disk, a drive seat slidably connected to the upper part of the rotating disk via the toothed rail, a sliding motor fixedly connected to the lower part of the drive seat, a drive gear fixedly sleeved at the output end of the sliding motor, and the bottom of the drive gear meshing with the upper teeth of the toothed rail.

[0006] A wire inlet is fixedly connected to one side of the drive base, and a roller frame is fixedly connected to the side of the drive base near the wire inlet. Pulling wheels are provided on both sides of the upper part of the roller frame, and driven wheels are rotatably connected on both sides of the lower part of the roller frame at positions corresponding to the pulling wheels. A wire pulling motor is fixedly connected to the upper part of the drive base at positions corresponding to the two pulling wheels.

[0007] The drive seat is fixedly connected to the end away from the inlet seat. The end of the outlet seat away from the roller frame is rotatably connected to the top of the outlet seat. A spring-loaded component is provided at the lower part of the outlet seat away from the roller frame, corresponding to the bottom of the nodding device. A cable bundle is provided through the inside of the nodding device at the position corresponding to the outlet area of ​​the outlet seat.

[0008] According to the aforementioned wire terminal processing tooling, a servo motor for driving the rotating disk is provided at the bottom of the rotating disk.

[0009] According to the aforementioned wire terminal processing tooling, the sliding motor and the two wire pulling motors are all stepper motors.

[0010] According to the wire terminal processing tooling described above, the output ends of the two wire pulling motors are both connected to the corresponding wire pulling wheels via a drive base.

[0011] According to the wire terminal processing tool, the wire inlet seat is located between the wire pull wheel and the driven wheel, and the roller frame has a wire bundling hole located between the wire pull wheel and the driven wheel.

[0012] According to the aforementioned wire terminal processing tooling, both of the wire pull wheels and the driven wheel are plastic rollers, and the two wire pull wheels and the corresponding driven wheel are tangent vertically.

[0013] According to the aforementioned wire terminal processing tooling, the springback component is an M-shaped spring fixed to the bottom of the wire outlet.

[0014] The above solution has at least one of the following beneficial effects:

[0015] Compared with the prior art, this utility model, by installing a nodulator on the wire outlet, allows the terminal crimping machine to operate. By connecting a pressure rod above the nodulator to the lifting seat responsible for crimping, the nodulator is pressed down first when the terminal crimping machine presses down, causing the wire to bend stably and pressing the end of the wire onto the terminal piece. At the same time, the wire length can be adjusted in real time through two pull wheels and two driven wheels to compensate for the wire, avoiding the inward displacement of the end caused by the bending of the wire, ensuring the processing yield, and enhancing the practicality of the device.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

A drive gear 5 is fixedly sleeved at the output end of the sliding motor 4. The bottom of the drive gear 5 meshes with the upper teeth of the gear rail 2, which allows the entire mechanism to rotate and move forward and backward at the same time, making it convenient to transfer the wire to different processing stations.

[0026] A cable inlet 6 is fixedly connected to one side of the drive base 3. A roller frame 7 is fixedly connected to the side of the drive base 3 near the cable inlet 6. Cable pull wheels 8 are provided on both upper sides of the roller frame 7. Driven wheels 9 are rotatably connected on both lower sides of the roller frame 7 at positions corresponding to the cable pull wheels 8. Both cable pull wheels 8 and driven wheels 9 are plastic rollers, and both cable pull wheels 8 and their corresponding driven wheels 9 are vertically tangent. The cable inlet 6 is positioned between the cable pull wheels 8 and the driven wheels 9. The roller frame 7 is positioned between the cable pull wheels 8 and the driven wheels 9. A cable harness hole 11 is provided. A cable pulling motor 10 is fixedly connected to the upper part of the drive base 3 at a position corresponding to the two cable pulling wheels 8. The output ends of the two cable pulling motors 10 pass through the drive base 3 and are connected to the corresponding cable pulling wheels 8 for transmission. The sliding motor 4 and the two cable pulling motors 10 are both stepper motors. When working, the two cable pulling wheels 8 and the two driven wheels 9 can adjust the cable length in real time under the drive of the cable pulling motors 10, thereby compensating for the cable and avoiding the inward displacement of the end caused by the bending of the cable.

[0027] A cable outlet 12 is fixedly connected to the end of the drive seat 3 away from the cable inlet seat 6. A tipper 13 is rotatably connected to the upper part of the end of the cable outlet 12 away from the roller frame 7. The cable outlet 12 and the tipper 13 are configured with limited rotation. A spring return component 14 is provided at the lower part of the end of the cable outlet 12 away from the roller frame 7, corresponding to the bottom of the tipper 13.

By connecting a pressure rod above the nodding device 13 to the lifting seat responsible for crimping, the terminal crimping machine first presses down the nodding device 13, causing the wire to bend stably between the nodding device 13 and the wire outlet 12, thereby pressing the end of the wire onto the terminal piece. At the same time, the wire length can be adjusted in real time by the two pull wheels 8 and two driven wheels 9 driven by the wire pull motor 10, compensating for the wire and avoiding the inward displacement of the end caused by the bending of the wire, thus ensuring the processing yield.
