Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing devices, in particular to a wire harness terminal servo crimping machine. Background Art

[0002] In previous industrial production, electrical connections often rely on manual operation, which is inefficient and inaccurate, and cannot guarantee the consistency and stability of the connection. With the popularization of various electronic and mechanical equipment, electrical connections have become more complicated, so a more efficient and reliable connection method is needed. The wire harness terminal servo crimping machine was created to meet this demand. This technology represents the important application and development trend of automated production in the field of electrical connections.

[0003] The mechanical structure of the existing wire harness terminal servo crimping machine is usually composed of a crimping head, a crimping arm, a transmission device, etc., among which the crimping head is the key component to realize the crimping of the wire harness terminal. When working, the wire harness terminal to be crimped is first placed under the crimping head, and then the motor is controlled to realize the movement of the crimping head. According to the distance and force requirements between the crimping head and the terminal, the movement trajectory and force of the motor are accurately controlled. After the crimping head is pressed down to the preset position, appropriate pressure is applied for crimping to ensure a good connection between the terminal and the wire harness.

[0004] However, when the existing wire harness terminal servo crimping machine is working, the wire harness terminal to be crimped is generally placed under the crimping head manually, and then the motor is controlled to realize the movement of the crimping head. This manual loading method is relatively inefficient because the operator needs to spend time to accurately place each terminal, resulting in low production efficiency. Therefore, a wire harness terminal servo crimping machine is proposed to solve the above problems. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a servo crimping machine for wiring harness terminals, comprising a loading platform 1, a servo motor 2 is fixedly connected inside the loading platform 1, a worm 3 is fixedly connected to the output end of the servo motor 2, a worm wheel 4 is rotatably connected inside the loading platform 1, the worm wheel 4 is meshed with the worm 3, a disc 5 is fixedly connected to the top of the worm wheel 4, a groove 6 is provided inside the disc 5, a support column 7 is fixedly connected to the top of the loading platform 1, a crimping groove 10 is provided inside the loading platform 1, a cylinder 8 is fixedly connected inside the support column 7, a crimping block 9 is fixedly connected to the output end of the cylinder 8, and a fixed component is provided on the outer wall of the loading platform 1;

[0025] Specifically, when using the wire harness terminal servo crimping machine, first start the servo motor 2, then drive the worm 3 to rotate through the servo motor, and then drive the disc 5 to rotate through the cooperation of the worm gear 4. Under the rotation of the first pair of discs 5, the wire harness is driven to move to the next pair of discs 5. The feeding mechanism is provided with three pairs of discs 5, which can guide the movement of the wire harness. When one end of the wire harness reaches the crimping groove 10, the servo motor 2 stops rotating, and then the cylinder 8 is started. The cylinder 8 pushes the crimping block 9 to crimp. After the crimping is completed, it is pressed again. Start the servo motor 2, and then the disc 5 drives the wire harness to move. There is also a pair of discs 5 on one side of the crimping assembly. After the crimping of one end of the wire harness is completed, the disc 5 can continue to drive the wire harness to move, thereby guiding the other end of the wire harness to enter the crimping position, and then start the cylinder 8 again for crimping. After all the two ends of the wire harness are crimped, the disc 5 on one side of the crimping assembly continues to drive the wire harness to enter the next step. This structure only requires manual placement of one end of the wire harness into the notch of the loading table 1, and does not require manual alignment of the wire harness with the crimping assembly, thereby improving the yield rate.

[0026] Reference Figure 1 - Figure 3 The fixing assembly includes a connecting block 11 and a fixing bolt 12, the inner thread of the connecting block 11 is connected to the outer wall of the fixing bolt 12, and the outer wall of the fixing bolt 12 is connected to the inner part of the loading platform 1 by thread;

[0027] Specifically, when the wire harness terminal servo crimping machine needs to be maintained or overhauled, the fixing bolt 12 is first rotated, and after the fixing bolt 12 is removed, the connecting block 11 is removed and maintenance or overhaul can be performed.

[0028] Reference Figure 2 - Figure 4 A discharge platform 13 is fixedly connected to one side of the outer wall of the loading platform 1, a servo motor 14 is fixedly connected inside the discharge platform 13, a worm 15 is fixedly connected to the output end of the servo motor 14, a worm gear 16 is rotatably connected inside the discharge platform 13, the worm 15 is meshed with the worm gear 16, a screw 17 is fixedly connected to one side of the outer wall of the worm gear 16, a slider 18 is threadedly connected to the outer wall of the screw 17, a slide groove 19 is opened inside the loading platform 1, the outer wall of the slider 18 is slidably connected inside the slide groove 19, a push block 20 is fixedly connected to the top of the slider 18, a collecting bucket 21 is fixedly connected to one side of the outer wall of the discharge platform 13, and a groove 22 is opened inside the discharge platform 13;

[0029] Specifically, when using the wire harness terminal servo crimping machine, after the wire harness crimping is completed, the wire harness is transported to the groove 22 in the unloading table 13 through the disc 5, and the servo motor 2 14 is started at this time. The servo motor 2 14 will drive the worm 2 15 to rotate, and then drive the screw 17 to rotate through the worm gear 2 16, so that the slider 18 drives the push block 20 to push the crimped wire harness into the collection bucket 21 for collection. After the end, the servo motor 2 14 drives the push block 20 to return and prepare to push the next wire harness. The device does not require manual collection of each wire harness. After the collection box 21 is full, the staff only needs to collect it in a centralized manner. This can unleash the creativity of employees and allow them to focus on more complex and innovative tasks rather than repetitive labor.

[0030] Working principle: When using the servo crimping machine for wire harness terminals, first start the servo motor 2, then put the wire harness into the notch at one end of the loading table 1, and after the servo motor 2 is started, it drives the worm 3 to rotate, and then the worm 3 drives the worm wheel 4 to rotate, and finally the disc 5 is driven by the worm wheel 4 to rotate, and the disc 5 rotates and drives the wire harness to move until one end of the wire harness reaches the crimping groove 10, and then start the cylinder 8, and the cylinder 8 drives the crimping block 9 to crimp one end of the wire harness. After the crimping is completed, start again. The servo motor 1 2 is started to continue to drive the wire harness until the other end of the wire harness reaches the crimping groove 10, and then the cylinder 8 is started again to crimp it. After the crimping is completed, the wire harness is driven to the unloading table 13 through the rotation of the disc 5, and then the servo motor 2 14 is started. After the servo motor 2 14 is started, the worm 2 15 is driven to rotate, and then the worm 2 15 drives the screw rod 17 to rotate through the worm gear 2 16, and finally the push block 20 is driven by the rotation of the screw rod 17 to push the crimped wire harness to the collection bucket 21.
