The invention relates to a full-automatic precise tester for a secondary battery safety valve, mainly comprising a vibrating funnel, a material feeding orbit, a detecting orbit, a detecting device, a collecting device and a PLC control system. The vibrating funnel is installed above the material feeding orbit connected with the horizontal detecting orbit; one end of the detecting orbit connected with the material feeding orbit is provided with a material feeding mechanism and the other end thereof is provided with a detecting port; the detecting device is installed on the detecting port; the collecting device is installed below the detecting port; the vibrating funnel, the material feeding mechanism, the detecting device and the collecting device are connected with the PLC control system.The tester is capable of controlling to automatically feed materials, automatically detect, automatically classify and automatically collect through the PLC control system so as to reach a full-automatic operation without detecting by people; therefore, the tester can totally detect a product. The tester is accurate in tested result and high in testing efficiency, thereby avoiding the potential hazard existing in a safety valve caused by a test of manually sampling; moreover, the whole structure is compact and the system is stable with low product cost and use cost.
Description
technical field [0001] The invention relates to an automatic test device for a battery safety valve, in particular to a precision tester for fully automatic detection of multiple performances of a secondary battery safety valve. Background technique [0002] Secondary battery safety valve (hereinafter referred to as safety valve) is a control device for the safety performance of portable electronic products, electric tools, and electric toy batteries. It is usually a precision component that is welded or riveted by an upper cap, an explosion-proof ball, and a lower cap. When the gas inside the battery is too late to be consumed, the gas acts on the explosion-proof ball through the pores of the lower cap. When the pressure rises to a certain level, the explosion-proof ball elastically deforms and begins to deflate; when the internal pressure of the battery drops to a certain level, the explosion-proof ball resumes deformation and closes the lower cover. The air hole, the open...
