Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harnesses, in particular to an automobile wiring harness sealing detection device. Background Art

[0002] The automotive wiring harness is the overall service equipment for a certain load source group in the car, such as relay lines, switching devices, control systems, etc.; it has very high requirements for its internal air tightness. In order to ensure the waterproof sealing of the wiring harness joints, the wiring harness needs to be tested for air tightness before leaving the factory, and the area near the wiring harness joint needs to be sealed before the wiring harness is placed in the air tightness tester for testing.

[0003] An existing wire harness air tightness detection device generally includes a base, on which a lower mold for placing the wire harness is installed, and an upper mold controlled by a hydraulic system is installed above the base. The upper mold is connected to the air supply system and a sealing silicone layer is provided on the surface. A sealing groove is provided on the surface of the lower mold, and a wire harness placement groove is provided in the sealing groove. When in use, the wire harness is placed in the wire harness placement groove, and the upper mold is closed with the lower mold under the control of the hydraulic system to seal the sealing groove and the wire harness placement groove. The air supply system supplies air to the wire harness and measures the internal air pressure change.

[0004] The above-mentioned prior art solutions have the following defects: since both the upper mold and the lower mold are exposed to the outside world and lack protective facilities, after long-term use, external dust and foreign particles are easily adhered and accumulated on the sealing silicone layer or the joints between the automobile wiring harness and the wiring harness placement groove, resulting in a significant decrease in the sealing of the equipment when the mold is closed, affecting the accuracy of airtightness detection. Utility Model Content

[0005] The utility model aims to provide a device for detecting the sealing performance of automobile wiring harnesses.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] It includes a base plate, a lower mold is fixedly provided on the top wall of the base plate, a sealing groove is provided on the outer wall of the lower mold, a placement groove for placing a wire harness is provided at the bottom of the sealing groove, a plurality of pillars are fixedly provided on the top wall of the base plate, a mounting plate is supported on the top of the pillars, a hydraulically driven upper mold is fixedly provided on a side of the mounting plate close to the lower mold, the upper mold is matched with a pressurized pipe, a sealing silicone sheet matching the sealing groove and the placement groove is fixedly provided on a side of the upper mold close to the lower mold, a protective box body wrapping the outer edge of the mounting plate is fixedly provided on the top wall of the base plate, a transfer box is connected to the outer side wall of the protective box body, a wire harness placement port is provided on a side of the transfer box away from the protective box body, the transfer box is externally connected to a dust removal duct and an exhaust duct, and an elastic rubber glove is provided through the outer wall of the protective box body.

[0008] By adopting the above technical solution, when in use, a batch of automobile wiring harnesses are first placed in the transfer box through the wiring harness placement port. The dust removal air duct can continuously blow high-speed airflow into the transfer box to blow the automobile wiring harness away the dust on its surface. The dust is discharged from the exhaust duct following the airflow. After the dust cleans the outer wall, the operator puts on elastic rubber gloves, sends the wiring harness into the protective box, places it in the placement groove of the lower mold, and closes the mold for air tightness detection. Since the interior of the protective box is a closed space and the automobile wiring harness has been dust-removed, dust and impurity particles will not enter the area where the upper mold and the lower mold are located, and are not easy to adhere to the sealing silicone sheet or the contact surface between the automobile wiring harness and the placement groove. The equipment maintains good sealing as a whole during detection to avoid deviations in air tightness detection results caused by impurities and foreign matter affecting the sealing effect of the equipment.

[0009] Furthermore, a detection entrance connected to the inside of the protection box is provided on one side of the transfer box close to the protection box body, a first cover plate covering the wiring harness placement box is hingedly provided on the outer wall of the transfer box, and a second cover plate covering the detection entrance is hingedly provided on the inner wall of the protection box body, and the first cover plate and the second cover plate are matched with buckles for fastening the box body.

[0010] By adopting the above technical solution, the first cover and the second cover are both in the closed state by default. When in use, open the first cover to put in a batch of automotive wiring harnesses, close the first cover and perform dust removal. After dust removal, put on elastic rubber gloves to open the second cover from the inside, take out the clean automotive wiring harnesses and place them in the placement slot for air tightness testing. The opening and closing of the first cover and the second cover are organically controlled to ensure the cleanliness of the automotive wiring harnesses and prevent dust and foreign matter from entering the testing equipment from the outside.

[0011] Furthermore, a delivery hole is provided on one side of the substrate close to the placement groove, a temporary storage bin is provided on the bottom wall of the substrate for sliding fit, the temporary storage bin covers the delivery hole, a slide rail is installed on the top wall of the substrate along the sliding direction of the temporary storage bin, and a slider that engages with the slide rail is extended from the outer edge of one side of the temporary storage bin close to the substrate.

[0012] By adopting the above technical scheme, the delivery hole is combined with the temporary storage bin. After the air tightness test is completed, the automobile wiring harness is delivered from the delivery hole, and the automobile wiring harness can be taken out by opening the temporary storage bin, which is convenient for the collection and transportation of the automobile wiring harness. At the same time, two sets of delivery holes and temporary storage bins can even be set to facilitate the distinction between good products and defective products.

[0013] Furthermore, an intercepting plate provided with a cut-off delivery hole is embedded in the side wall of the substrate, and one end of the intercepting plate passes through the outer wall of the substrate and is provided with a pulling hole.

[0014] By adopting the above technical solution, the setting of the intercepting plate has a good sealing effect. When it is necessary to open the temporary storage bin and take out the internal automotive wiring harness, dust and impurities in the air may invade the interior of the protective box from the delivery hole. At this time, the intercepting plate is inserted to completely seal the delivery hole, thereby preventing dust and impurities from invading from the delivery hole.

[0015] In summary, the beneficial technical effects of the utility model are:

[0016] 1. The transfer box, dust removal duct, exhaust pipe and elastic rubber gloves are used to ensure good sealing of the equipment, avoiding the deviation of air tightness test results caused by impurities and foreign matter affecting the sealing effect of the equipment;

[0017] 2. The first cover plate and the second cover plate are used to ensure the cleanliness of the automobile wiring harness and prevent dust and foreign matter from entering the detection equipment from the outside;

[0018] 3. An interception plate is used to completely seal the delivery hole and prevent dust and impurities from invading from the delivery hole. BRIEF DESCRIPTION OF THE DRAWINGS
