Detecting device for resettable fuses of lead-acid batteries

Abstract

The invention discloses a detecting device for resettable fuses of lead-acid batteries. The detecting device comprises a power supply module, a detecting module and a control module. The detecting module comprises a detecting circuit and a detecting unit, the detecting circuit comprises loads, a first connecting end and a second connecting end, the first connecting end and the second connecting end are respectively connected to two ends of a resettable fuse, the detecting circuit is serially connected with the power supply module, a detecting signal outputted by the control module is transmitted back to the control module after being transmitted through the detecting unit and the resettable fuse, and the control module is used for generating a test result according to the returned detecting signal. The detecting signal outputted by the control module is transmitted back to the control module after being transmitted through the detecting unit and the resettable fuse, so that the control module can generate the test result according to the returned detecting signal. The detecting device has the advantages that a welding connection condition of the resettable fuse can be quickly detected, the quality of the resettable fuse can be automatically distinguished, misjudgment caused by observation by the aid of eyes of an operator is avoided, mental fatigue of the operator can be relieved, and the qualified rate of products and the production benefit are increased.

Description

technical field [0001] The application relates to the field of lead-acid storage battery production, in particular to a detection device for self-recovery insurance of lead-acid storage batteries. Background technique [0002] Lead-acid batteries are widely used in various fields because of their low price, reliable quality, large capacity range, easy maintenance, and long service life. Because this battery is mainly used in children's toys, it is very important for the safety of electrical circuits, so A self-recovery fuse is installed inside the battery. In the event of a short circuit in the external circuit, the internal fuse of the battery is automatically disconnected to prevent electrical circuit fires and ensure personal safety. [0003] In the battery manufacturing process, there is a process of safety welding, that is, after the installed battery is sealed, it is the safety welding process, and then the terminal and safety glue filling process. After the safety is ...

Problems solved by technology

In the existing technology, manual methods are generally used to detect whether the self-recovery insurance is qualified. If you use your eyes to observe whether the battery welding is in good condition, it is difficult to accurately judge. If bad products flow into the next process, it will cause the battery to break or the self-recovery insurance to be short-circuited. , resulting in a spent battery
