Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a tensile testing machine for detecting welding of a coil core tab of a micro button battery. Background Art

[0002] Button batteries, also known as coin-cell batteries, are small batteries shaped like a button and are widely used in various electronic products. Their small size, light weight, and high energy density make them an ideal power source for portable devices. They are named after their large diameter and thin thickness, resembling the dimensions of a small button. Button batteries are primarily used in computer motherboards, MP3 watches, calculators, IC cards, electronic dictionaries, tax control machines, Bluetooth headsets, hand-cranked rechargeable flashlights, toy walkie-talkies, and other products. Furthermore, button batteries are used as backup power sources for various electronic products, including TWS headsets, wireless sensor networks, smoke alarms, portable medical devices, data acquisition terminals, electronic toys, remote controls, computer peripherals, and portable audio equipment. Types of button batteries include lithium-iron button batteries, which offer high discharge capacity, a smooth discharge curve, excellent high and low temperature performance, and are environmentally friendly. Lithium iron button batteries are lighter and have a longer shelf life, up to ten years in low-temperature, dry conditions. A tensile testing machine specifically designed to inspect the tab welds on miniature button battery cores is a device specifically designed to test the quality of these tab welds. The machine's basic principle is that it mechanically applies a gradually increasing axial tensile force to the tabs. This force simulates the forces experienced by the tabs during actual battery use, production, or specific testing environments. With the development of society, tensile testing machines are increasingly used when inspecting the tab welds on button battery cores.

[0003] When workers need to test materials, they place the materials on the tensile testing machine so that the tensile testing machine can perform tensile testing on the materials. However, after repeated use of the tensile testing machine, the clamping end of the tensile testing machine will be severely worn, causing the workers to use auxiliary tools to disassemble and replace the clamping blocks, which in turn causes the workers to encounter time-consuming problems in the process of replacing the clamping blocks.
