Description

Air tightness testing device for key point adhesive cover Technical Field The utility model relates to the technical field of airtight testing, in particular to an airtight testing device for an upper cover of a key point adhesive. Background In the traditional instrument panel air tightness detection process, a special instrument is generally adopted to carry out positive pressure air tightness test in a mode of upper and lower die closing, but the technology has certain defects. The equipment realizes basic positioning only through a mechanical limiting block, a product in-place detection sensor and a cover plate closing confirmation device are not integrated, forced testing is carried out when a workpiece is not positioned completely or the cover plate is not sealed completely due to operation negligence, the risk of workpiece popup injury exists, the service life of the element is shortened due to an air pressure impact sensor, error data are required to be repeatedly inspected, the detection time is increased by 30%, a manufacturer displays that the equipment failure rate caused by the abnormal condition of the cover plate is up to 2.7%, and the service cost of the equipment exceeds 15 ten thousand yuan. It is therefore desirable to provide a device for testing the airtight of a touch-sensitive adhesive cover. Disclosure of utility model The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide the device for testing the airtight of the key point adhesive cover. In order to solve the technical problems, the technical scheme includes that the device for testing the airtight performance of the key adhesive dispensing cover comprises a tool for testing the airtight performance, wherein a positioning seat is arranged in the tool, the top of the positioning seat is rotationally connected with a pressing plate, a circle of groove II is formed in the top of the positioning seat, a groove III is formed in the center of the pressing plate, a jig is placed in the groove II, and a meter panel to be tested for the airtight performance is placed in the jig; The rear end fixedly connected with actuating mechanism of positioning seat, actuating mechanism's front end is rotated with the top of clamp plate and is connected, the top front end fixedly connected with two hasp backing plates of clamp plate.
