Description

Technical Field

[0001] The invention relates to the technical field of wire harness appearance detection, and in particular to a wire harness appearance detection machine. Background Art

[0002] Industrial wiring harness refers to a group of wires, cables and related components used in the industrial field to connect electrical equipment and transmit electrical energy or signals. They are usually used to ensure the normal operation of electrical systems and accurate transmission of signals. Wiring harnesses usually contain protective layers, such as insulation layers, sheaths or braided layers to protect the wires from physical damage and environmental influences. The wires in the wiring harness are interconnected through components such as terminals, connectors or terminals to ensure the reliability of electrical connections. As a key node for circuit connection and signal connection, the appearance quality of the wiring harness directly affects the transmission of current and the stability of signals, and is related to the safety of the entire circuit system. Once there are defects in the appearance, such as damage, rust, deformation, etc., it may cause circuit failures and even cause safety accidents.

[0003] At present, a Chinese patent with publication number CN220063876U discloses a wire harness appearance inspection machine, which includes a base, a sliding component, a mounting plate, a detection component, a shell, a controller, a display, and a driver. During the inspection, the utility model places multiple wire harnesses on a fixed groove, and then places a fixed mold on the mounting plate. The mounting plate is driven by the driver so that the mounting plate is located below the detection component. The camera takes a photo of the multiple wire harnesses at one time, and then the controller is used to inspect the wire harnesses. This wire harness appearance inspection machine can take photos and inspect multiple wire harnesses at one time, and the shell can prevent external light interference, and there is also an optical compensator to perform light compensation when taking photos.

[0004] However, the above-mentioned public document still has defects. During the inspection process, since the camera is always located above the wiring harness, no matter how the wiring harness moves, the camera cannot capture all parts of the wiring harness. There are always blind spots in the inspection process, and the appearance defects of the wiring harness cannot be completely detected. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a wire harness appearance inspection machine, and the above technical purpose is achieved through the following technical solutions: A wire harness appearance inspection machine comprises a detection machine base, an industrial wire harness to be inspected is arranged on the upper part of the detection machine base, a wire harness scanner fixed to the upper part of the detection machine base is arranged on one side of the industrial wire harness, a scanning slot matching the shape of the industrial wire harness is arranged inside the wire harness scanner, a wire harness stabilizing mechanism for support is arranged outside the industrial wire harness, the wire harness stabilizing mechanism comprises a wire harness ring, the wire harness ring is sleeved on the outside of the industrial wire harness, a wire harness pushing mechanism for pushing the industrial wire harness into the wire harness scanner is arranged at one end of the industrial wire harness, the wire harness pushing mechanism comprises a wire pushing plate, a card slot for inserting the industrial wire harness is fixed on the wire pushing plate.

A moving block 18 matching the screw rod 16 is provided on the outside of the screw rod 16. The screw rod 16 is controlled to rotate and control the lateral movement of the moving block 18.

[0020] The wire harness pushing mechanism also includes a connecting bracket 8, a cylinder 9, and a cylinder connecting plate 10. The connecting bracket 8 is fixed to one side of the wire pushing plate 4 by means of a connection between a stud and a nut. The connecting bracket 8 is arranged close to the wire pushing plate 4, and the cylinder 9 is fixed to the upper end of the detection machine base 1.

[0021] An auxiliary movable track 19 is fixedly provided on the upper end of the detection machine base 1. The auxiliary movable track 19 is arranged directly below the wire pushing plate 4. An auxiliary support plate 20 that moves along the auxiliary movable track 19 is provided above the auxiliary movable track 19. The upper end of the auxiliary support plate 20 is fixedly connected to the lower end of the wire pushing plate 4.

[0022] A wire harness feeding mechanism is also provided at the upper end of the detection machine base 1. The wire harness feeding mechanism itself is driven by a servo motor 17. The wire harness feeding mechanism includes a support column 11, a feeding platform 12, a feeding track 13, a feeding slider 14, and a wire harness support block 15.

[0025] When starting the inspection work, the inspector places the industrial wire harness on top of the wire harness support block 15.

During this process, the cylinder 9 controls the wire pushing plate 4 to support the right end of the industrial wire harness through the cylinder connecting plate 10. The right end of the industrial wire harness is inserted into the slot of the wire pushing plate 4, and the wire harness ring 3 also comes to the position on one side of the wire harness scanner 2 to support the left end of the industrial wire harness. At this time, the feeding slider 14 drives the wire harness support plate to reset.

[0027] Subsequently, the cylinder 9 continues to control the wire pushing plate 4 to move toward the wire harness scanner 2, and pushes the industrial wire harness into the wire harness scanner 2.
