Spot welding detection device and spot welding detection method for nickel sheets of fuses

Abstract

The invention provides a spot welding detection device and a spot welding detection method for nickel sheets of fuses, and particularly relates to the field of spot welding detection. The spot welding detection method is implemented by the spot welding detection device and a jig. The spot welding detection device comprises a transverse rod, a worktable, a support rod, a force gauge and a hinge. The support rod is perpendicularly fixed to a base plane of the worktable, the transverse rod is connected with the support rod by the hinge in a cross manner and can rotate around the hinge, an end of the transverse rod is connected with one end of the force gauge, a detection needle is arranged at the other end of the force gauge, and the force gauge is further provided with a display screen. The spot welding detection method includes placing to-be-detected materials in the jig; placing the jig above the worktable; extending the detection needle into gaps between the nickel sheets and the fuses; keeping a shell of the force gauge from the jig by distances; pushing the ends of the transverse rod; stopping pushing the transverse rod when numerical values displayed on the display screen reach standard values; allowing the transverse rod to stand still for the duration ranging from 1 second to 5 seconds; recording data; observing conditions of welding spots. The spot welding detection device and the spot welding detection method have the advantages that spot welding detection can be easily, conveniently and accurately carried out on the fuses, accordingly, the production efficiency can be improved, the detection cost can be reduced, and the spot welding detection device and the spot welding detection method can bring convenience for recording the test data.

Description

technical field [0001] The invention belongs to the field of spot welding detection, and in particular relates to a spot welding detection device and a detection method for a nickel sheet of a fuse. Background technique [0002] The fuse in the lithium battery pack is one of the essential safety components. Both ends of the fuse are connected to the lithium battery through welded nickel sheets. Because spot welding has the advantages of high efficiency, low energy consumption, and high output, the current nickel sheet welding Spot welding is often used; in spot welding operations, it is inevitable that there will be false welding, which will easily lead to aging and peeling, which will directly affect whether the fuse can be stably connected to the lithium battery. Therefore, it is guaranteed to avoid false welding during spot welding inspection An important step in the quality of spot welds. The current spot welding detection of nickel sheets mostly adopts ultrasonic waves...
