Technical Field

[0001] This invention relates to the field of oil pan testing equipment technology, specifically to an oil pan testing production line. Background Technology

[0002] During the production process, the oil pan needs to be tested for air tightness and then purged. However, the existing production line's purging equipment often uses compressed air for simple purging, which lacks comprehensive purging of the entire oil pan, resulting in omissions in the purging process. Based on the above problems, it is necessary to improve the oil pan production equipment. Summary of the Invention

[0003] This invention proposes an oil pan testing production line, which solves the problem of insufficient comprehensiveness in oil pan purging in the prior art.

[0004] The technical solution of the present invention is as follows: An oil pan inspection production line includes an airtightness inspection station, a rejection station, a steel sleeve inspection station, a purging station, and a material unloading station. The production line also includes a handling device for transporting materials between adjacent stations. The purging station includes a compressed air tank, a purging box, a tilting purging assembly, and an air curtain purging unit. The tilting purging assembly is movably disposed above the purging box, and the air curtain purging unit is disposed at the bottom of the purging box. The tilting purging assembly includes a moving base plate, a tilting drive unit, a loading plate, and multiple purging heads. The tilting drive unit drives the loading plate to tilt, and the multiple purging heads are arrayed on the loading plate. The tilting drive unit is disposed on the moving base plate.

[0005] When the moving substrate passes through the air curtain blowing unit, the flipping drive unit drives the loading plate to rotate.

[0006] The airtightness testing station includes a station base, a slide rail, a lower airtight carrier, an upper airtight cover, a lifting bracket, and a lifting drive unit. The slide rail is mounted on the station base. The lower airtight carrier is slidably mounted on the slide rail, and its sliding direction is perpendicular to the transport direction of the transport device. The lifting bracket is located in the middle area of ​​the slide rail. The lifting drive unit is mounted on the lifting bracket, and the lifting drive unit drives the upper airtight cover to move up and down vertically.

[0007] The rejection station includes a rejection conveyor belt and a recycling bin, with the recycling bin located on the discharge side of the rejection conveyor belt.

The transport track is mounted on the transport bracket, the movable seat is movably mounted on the transport track, the lifting arm is mounted on the movable seat, and the suction cup unit is located at the end of the lifting arm.

[0011] The working principle and beneficial effects of this invention are as follows: This invention discloses an oil pan inspection production line. The oil pan, transported by a conveying device, first undergoes an airtightness test at an airtightness testing station. If the airtightness test is successful, the conveying unit moves it to a steel sleeve inspection station. If the airtightness test fails, it is moved to a rejection station for recycling and removal. At the steel sleeve inspection station, the position of the steel sleeve installed on the oil pan is checked to confirm proper installation. Then, at the purging station, the oil pan is installed onto a loading plate. The fixing method can be vacuum adsorption or snap-fit. The loading plate is equipped with multiple blowers... The sweeping head performs preliminary cleaning of the surface and interior of the oil pan. The debris blown off falls into the cleaning box below. At the same time, an air curtain cleaning unit is set at the bottom of the cleaning box. The air curtain cleaning unit forms an air curtain through multiple flat cleaning nozzles. The flipping drive unit flips the oil pan so that the air curtain can clean the entire surface of the oil pan. The moving plate can move the oil pan closer to or away from the area of ​​the air curtain, thereby realizing cleaning in different states. After cleaning, the oil pan is sorted and stored at the unloading station, thus solving the problem of incomplete cleaning of the oil pan in the prior art. Attached Figure Description
