Description

Technical Field

[0001] The present application relates to the technical field of wire harness detection equipment, and specifically to a CCD 360° detection mechanism for a wire harness end portion. Background Art

[0002] Wire harness end CCD inspection is a technology used to detect the quality of wire harness ends. CCD is an image sensor that can efficiently capture images and analyze them to detect physical defects at the wire harness ends, such as broken wires, short circuits, poor contact, etc.

The test platform is set outside the wire harness transmission mechanism, and a mounting plate is vertically set on the upper surface of the test platform. A first CCD sensor and a second CCD sensor are installed on the side of the mounting plate close to the wire harness transmission mechanism. The first CCD sensor is used to take pictures containing wire harness crimped terminals, and the second CCD sensor is used to take pictures containing wire harness line numbers. The wire harness transmission mechanism is used to install a number of wire harnesses, and the wire harnesses move with the wire harness transmission mechanism.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0030] See also Figure 1-4 , the embodiment provided by the utility model:

[0031] A 360° CCD detection mechanism for a wiring harness end comprises a mounting frame 1. A linear guide rail 2 is fixedly mounted on the bottom surface of the mounting frame 1. The linear guide rail 2 can control the position of a mounting plate on a detection table for easy adjustment.

[0032] A wire clamp mechanism 3 for clamping the wire harness is fixedly installed on one side of the top surface of the mounting frame 1. The wire clamp mechanism 3 includes an L-shaped plate 31, a finger cylinder 32 and a contoured clamping claw 33. The bottom end of the L-shaped plate 31 is installed on one side of the top surface of the mounting frame 1, the side wall of the L-shaped plate 31 is fixedly installed on the finger cylinder 32, and the contoured clamping claw 33 is installed on the fingers of the finger cylinder 32.

[0033] When the surface of the wire harness needs to be inspected, the fingers of the finger cylinder 32 are controlled to open and close, so that the contoured clamping claw 33 can clamp and fix the wire harness, so that the CCD assembly 6 can inspect the surface of the wire harness.

[0034] A support plate 4 is fixedly mounted on the top surface of the mounting frame 1, and a rotating mechanism 5 is fixedly mounted on the side wall of the supporting plate 4. The rotating mechanism 5 includes a fixed disk 51, a rotating seat 52, a servo motor 53 and a rotating frame 54. The fixed disk 51 is mounted on the side wall of the supporting plate 4. The rotating seat 52 rotates on the side wall of the fixed disk 51 by the servo motor 53 in conjunction with the gear and the annular tooth groove. The rotating frame 54 is fixedly mounted on the side wall of the rotating seat 52. A CCD component 6 for detecting the wire harness is fixedly mounted near the edge of the rotating frame 54.

[0035] The rotating mechanism 5 drives the CCD assembly 6 to shoot around the surface of the wire harness to be detected in a 360° direction. Specifically, the servo motor 53 drives the gear to rotate, so that the annular tooth groove inside the rotating seat 52 can rotate on the side wall of the support plate 4 through the bearing ring, and then drive the rotating frame 54 to rotate, so that the CCD assembly 6 can shoot around the surface of the wire harness to be detected, so that there is no viewing angle for the wire harness detection.

[0036] A cleaning mechanism is installed at the top of the side wall of the support plate 4, and the cleaning mechanism is placed horizontally on the support plate 4. The cleaning mechanism includes a moving mechanism, an air suction mechanism 8 and a blowing mechanism 7. The air suction mechanism 8 and the blowing mechanism 7 are installed in a plug-in manner. The moving end of the moving mechanism is fixedly installed on the side wall of the blowing mechanism 7. The moving mechanism is fixedly installed on the top of the side wall of the support plate 4. The cleaning mechanism is used to clean the dust and foreign matter remaining on the wiring harness, so as to obtain better detection effect.

[0037] Specifically, the blowing mechanism 7 includes a blowing sleeve 71, a hollow groove 72, an air inlet joint 73 and an air guide pipe 74. The side wall of the blowing sleeve 71 is penetrated by a hollow groove 72. The air inlet joint 73 is respectively installed on the side wall of the blowing sleeve 71. One end of the air guide pipe 74 is docked with the tail of the blowing sleeve 71. The moving mechanism includes a linear cylinder 75 and a moving seat 76. The linear cylinder 75 is fixedly installed on the top of the side wall of the support frame by screws. The moving seat 76 is fixedly installed with the telescopic shaft of the linear cylinder 75. The interior of the moving seat 76 is fixedly installed on the side wall of the air guide pipe 74.

[0038] The air intake connector 73 is connected to the air pump through an air pipe so that the air pump can supply air to the air intake connector 73. When the surface of the wiring harness needs to be cleaned, the air guide tube 74 is driven close to the wiring harness by the linear cylinder 75, so that the end of the wiring harness is placed in the hollow groove 72 in the blowing sleeve 71. The air intake connector 73 is blown into the hollow groove 72 through the air holes opened on the side wall of the blowing sleeve 71, and the end of the wiring harness is blown. During the blowing process, the dust and foreign matter on the surface of the wiring harness can be detached from the wiring harness, thereby removing the foreign matter and dust on the surface of the wiring harness, thereby improving the detection effect of the CCD component 6.

[0039] Furthermore, the suction mechanism 8 includes an air suction pump 81 and a foreign matter collection bag 82. The air inlet end of the air suction pump 81 is plugged into the air outlet end of the air guide pipe 74, and the air outlet end of the air suction pump 81 is connected to the foreign matter collection bag 82 through a clamp. The dust and foreign matter detached from the wiring harness enter the air suction pump 81 through the air guide pipe 74 under the suction force of the air suction pump 81, and are finally discharged into the inlet collection bag for collection and processing. It is worth noting that the foreign matter collection bag 82 is woven from fibers, and the surface allows airflow to pass through. In the process of airflow passing through, dust and foreign matter are filtered out, thereby achieving the effect of collecting foreign matter and dust.

[0040] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
