Abstract

The invention discloses a square lithium ion battery lug welding clamp. The square lithium ion battery lug welding clamp comprises a cover plate platform and a carrying platform arranged in parallel,wherein a fixed baffle plate is fixedly arranged at one end of the carrying platform while a telescopic mechanism is arranged at the other end of the carrying platform, side clamping devices are symmetrically arranged on two sides of the carrying platform, and the telescopic mechanism is slidably connected to the side clamping devices; the telescopic mechanism comprises a main shaft which is vertically and movable arranged in the carrying platform in a penetrating manner, one end of the main shaft is vertically connected to a movable baffle plate, and an end telescopic part is connected to themovable baffle plate; a connecting rod is vertically and fixedly arranged in the middle of the main shaft; each of the side clamping devices comprises a triangular track movably arranged in the carrying platform in a penetrating manner, the beveled edge of the triangular track and the end part of the connecting rod are matched to slide, and the outer end of the triangular track is connected to aside telescopic part through a side baffle plate. The periphery of a roll core is limited by means of the fixed baffle plate, the movable baffle plate and side baffle plates on the two side clamping devices, so that accurate positioning is achieved, and therefore, the welding quality is guaranteed.

Description

technical field [0001] The invention relates to the field of lithium battery production, in particular to a square lithium ion battery tab welding fixture. Background technique [0002] Lithium-ion batteries consist of winding cores, electrolytes, cover plates, cover plates, etc. The cores of lithium-ion batteries are made of positive electrode sheets, negative electrode sheets, and separators stacked or wound alternately. The positive and negative electrode sheets are Laser cutting is used to process tabs at one end of the pole piece, and then the active material slurry is coated and solidified. With the innovation of new energy technology, lithium-ion battery products are also diversifying. In the existing technology, the commonly used positive and negative electrodes of the winding core are mostly aluminum foil and copper foil. This increases the difficulty of welding between the lug and the connecting piece of the cover plate. Tab welding is generally performed manuall...
