End cap welding mechanism

Abstract

The invention discloses an end cap welding mechanism. The end cap welding mechanism comprises a platen, wherein an electric cam push mechanism is arranged below the platen; a housing clamping mechanism is arranged above the platen; the two sides of the housing clamping mechanism are separately equipped with an end cap clamping mechanism and a laser welding mechanism; the electric cam push mechanism is equipped with a first transmission rod and a second transmission rod; the electric cam push mechanism slides up and down for driving the first transmission rod to swing around a first rotary shaft to drive the end cap clamping mechanism to move front and rear, so that a fitting block presses a lug to fit to an end cap; the electric cam push mechanism slides up and down for driving the secondtransmission rod to swing around the first rotary shaft to drive the housing clamping mechanism to move front and rear, so that the clamp clamps the housing; and the laser welding mechanism regulatesthe position of a laser unit through a horizontal transplanting platform and a laser unit transplanting mechanism, so that a laser spot of the laser unit is kept consistent with the lug and the end cap, and therefore, welding precision between the lug and the end cap is guaranteed.

Description

technical field [0001] The invention relates to the field of end cap welding, in particular to an end cap welding mechanism. Background technique [0002] With the increasing shortage of renewable energy in the world, lithium-ion batteries have received more and more attention as a clean energy source; currently lithium-ion batteries are widely used in mobile phones, notebooks, backup power supplies, UPS, power tools, digital products and other products ; When a lithium-ion battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte; while the carbon as the negative electrode has a layered structure, it has many micropores, and the lithium ions that reach the negative electrode The ions are embedded in the micropores of the carbon layer, and the more lithium ions are embedded, the higher the charging capacity. [0003] During the production process of lithium-i...
