Description

Technical Field

[0001] The invention belongs to the technical field of wire harness production, and in particular relates to an automatic riveting machine for automobile wire harnesses. Background Art

[0002] For electronic products with precision welded wiring harnesses, in order to prevent the welding parts of the wiring harness and the circuit board from being pulled during the assembly process and causing quality defects such as breakage, it is necessary to press the bushing into the specified position of the wiring harness and position it through the bushing to ensure that the welding parts of the wiring harness and the circuit board are not damaged by external forces. In order to cooperate with the assembly of the product structure, the bushing has a precise pressing position limit on the wiring harness, and the bushing must be pressed in completely to prevent the wiring harness from shifting.

[0003] At present, the method of assembling bushings in the industry is manual installation. This operation method is likely to cause the bushings to be not pressed into place and the pressing force to be uneven, resulting in the inability to assemble the product and a large number of bushings being crushed and scrapped. At the same time, the position of the bushing cannot be accurately located by humans, which will cause the assembly to be unable to operate due to insufficient distance. Summary of the invention

[0004] The main technical problem solved by the present invention is to provide an automatic riveting machine for automobile wiring harnesses, which realizes the effect of using the device to replace manual riveting process, reduces the labor intensity of human labor, improves work efficiency, improves the consistency of the wiring harness after riveting, and saves production costs.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: an automatic riveting machine for automobile wiring harnesses, comprising a riveting frame, a riveting tool, a loading tool, a feeding tool, a leakage prevention tool and a riveting platform, wherein the riveting tool, the loading tool, the feeding tool, the leakage prevention tool and the riveting platform are all arranged on the riveting frame;

[0006] The riveting tool comprises a riveting head and a first cylinder driving the riveting head to move up and down;

[0007] The feeding tool comprises a base fixed to the riveting frame, the base is provided with a channel for the riveted parts to flow through and a limiting groove for positioning the riveted parts, one end of the channel is connected to the limiting groove, and the other end of the channel is connected to the vibration feeding mechanism;

[0008] The feeding tooling comprises a clamping mechanism, a second cylinder driving the clamping mechanism to move forward and backward, and a third cylinder driving the clamping mechanism to move up and down;

[0009] The clamp mechanism includes a first clamp arm, a second clamp arm, and a fourth cylinder for driving the first clamp arm and the second clamp arm to move closer to each other or to separate from each other;

[0010] The anti-leakage tooling includes a baffle and a fifth cylinder driving the baffle to move forward and backward, and the baffle is located below the first clamping arm and the second clamping arm;

[0011] The first cylinder, the second cylinder, the third cylinder, the fourth cylinder and the fifth cylinder are electrically connected to a controller, respectively.

[0012] The further technical solution adopted by the present invention to solve the technical problem is:

[0013] Furthermore, the fourth cylinder is connected to the piston rod of the third cylinder via a first connecting plate.

[0014] Furthermore, the third cylinder is connected to the piston rod of the second cylinder via a second connecting plate.

[0015] Furthermore, the fifth cylinder is fixedly mounted on the second connecting plate.

[0016] Furthermore, the second cylinder and the third cylinder are slide cylinders.

[0017] Furthermore, the fourth cylinder is a gripper cylinder.

[0018] Furthermore, the limiting groove is provided with a through hole, a suction cup is installed in the through hole, the suction cup is connected to a vacuum pump through a hose, and the vacuum pump is electrically connected to the controller.

[0019] Furthermore, photoelectric sensors are installed at both ends of the limit groove.

[0020] The beneficial effects of the present invention are as follows: the wiring harness shell to be riveted is placed on the riveting platform, and the riveted parts flow from the channel to the limiting groove one by one. When the photoelectric sensor senses that there is a riveted part in the limiting groove, the third cylinder drives the clamping jaw mechanism downward to approach the limiting groove, and the fourth cylinder drives the first clamping arm and the second clamping arm to approach each other to clamp the riveted part. At the same time, the fifth cylinder drives the baffle to move forward to the bottom of the riveted part, and then the second cylinder drives the clamping jaw mechanism to move forward to the specified position. Finally, the first cylinder drives the riveting head to move downward to achieve the pressing of the riveted part and the wiring harness shell, thereby achieving the effect of using the device to replace manual riveting process, reducing human labor intensity, improving work efficiency, and achieving good consistency of the wiring harness after riveting, saving production costs.
