Efficient pressure welding device for lithium battery cap

Abstract

The invention relates to the technical field of pressure welding, and discloses an efficient pressure welding device for a lithium battery cap. The device comprises a device shell, wherein a pressure welding head is fixedly arranged above the device shell; a guide pipe is fixedly connected right above the device shell; delivery wheels are fixedly arranged at the left side and the right side of the upper part of the inner side of the device shell; a storage box is fixedly connected to the lower part of the guide pipe; a conveyor belt is movably connected to the outer sides of delivery wheels; a fixing device outer frame is fixedly connected to the upper part of the conveyor belt; a lithium battery is placed on the upper part of the fixing device outer frame; a pressing plate is movably connected to the inner side of the center of the fixing device outer frame; and reset springs are fixedly connected to the left side and the right side of the center of the bottom of the pressing plate. Through cooperative use of the pressing plate, connecting blocks, movable rods, connecting springs, rotating plates, rotating shafts and clamping plates, the effects of fixing a lithium battery and preventing the lithium battery from being separated from the fixing device outer frame during pressure welding are achieved.

Description

technical field [0001] The invention relates to the field of pressure welding technology, in particular to a high-efficiency pressure welding device for lithium battery caps. Background technique [0002] Lithium battery cap In the production process of lithium batteries, it is convenient to use the whole lithium battery by pressure welding the lithium battery cap on the positive electrode of the battery. However, if the lithium battery itself is not fixed enough during pressure welding, the lithium battery will break down Topple over, the lithium battery cap cannot be pressure-welded on the lithium battery, but if it is fixed too tightly, it is inconvenient to remove the pressure-welded lithium battery, which makes it impossible to achieve stable pressure welding, so the present invention is hereby A high-efficiency pressure welding device for lithium battery caps is proposed to solve the above problems, to ensure stable pressure welding and to facilitate the staff to colle...
