Description
Technical Field
The utility model relates to a battery field, a battery end welding detection device specifically says so.
Background
Along with social development, the environmental pollution is aggravated and the traditional energy is exhausted day by day, so people have stronger and stronger awareness on environmental protection. The lithium ion battery has the advantages of high energy density, high voltage platform, small self-discharge, environmental protection and the like, and becomes the first choice of green energy. The spot welding is an indispensable step in the production process of the lithium ion battery, and a spot welding device cannot be separated from the production of the battery core to the assembly of the battery Pack. Especially in the production of cylindrical lithium ion batteries, spot bottom welding is an important process in the production, and the quality of spot welding at the bottom of the cylindrical lithium ion battery directly influences the quality of the battery. Once the cold joint is generated in the welding process of the bottom of the battery, the internal resistance of the battery is increased slightly, and the battery is scrapped seriously, so that the safety of the battery and the product percent of pass in the production process are directly influenced.
Disclosure of Invention
The utility model provides a simple structure, it is convenient to use, can satisfy many specifications battery and detect, improves efficiency of software testing's battery end welding detection device.
The utility model adopts the technical proposal that: the utility model provides a battery foot welding detection device which characterized in that: the battery clamping device comprises a base, wherein a clamping groove for accommodating a battery is formed in the base, a tension clamping test port is formed in one end of the clamping groove in the length direction, and locking screw holes for clamping and fixing the clamping groove on a tension testing machine are formed in the bases on the two sides in the width direction of the clamping groove.
Further, the base is made of aluminum or stainless steel.
Furthermore, the cross section of the clamping groove is square or circular arc.
Further, the tensile clamping test port is of an upward bayonet structure.
Furthermore, the other end of the clamping groove in the length direction is provided with an opening.
The utility model discloses a base of aluminium system or stainless steel is as tool equipment, be fixed in on the tensile test machine through the locking screw of base both sides, set up the draw-in groove of square or convex cross-section to circular or square battery, will be surveyed the battery sample by on the draw-in groove or in the draw-in groove of base is put into to the opening behind the draw-in groove, be convenient for stably place, the battery is put welded nickel strap at the bottom of putting and is placed in the tight test mouth of pulling force clamp, press from both sides tight nickel strap through tensile test machine upper portion pulling force and make tensile test, can be swift, the detection of welding effect at the bottom of the stable realization cylindrical lithium cell point, it is convenient to use, the draw-in groove is many sizes.
