Embodiment Construction

[0047] The technical solutions and beneficial effects of the present invention will be apparent through the detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0048] Such as figure 1 As shown, the present invention includes a battery feed mechanism 1, a cap material guide mechanism 5, a cap feed mechanism 6, a laser spot welding mechanism 7 and a control system (not shown) that controls the actions of the above-mentioned mechanisms. The battery feed mechanism 1 It is used to send the battery 3 to be processed into the spot welding welding station. The cap feeding mechanism 5 can introduce the caps 2 transported thereon and automatically arrange and advance them in sequence. The cap feeding mechanism 6 and the cap guiding mechanism The feeding mechanism 5 is matched and connected, and placed above the battery feeding mechanism 1, it can accept the cap 2 sent by the cap material guide mechanism 5, and send ...

Abstract

The invention relates to a cell cover and polar ear spot welding device, which comprises a cell feeding mechanism which can send cells to be processed into spot welding stations, a cover guiding mechanism which can lead in covers and automatically and progressively arrange the covers in order, a cover feeding mechanism which accommodates the covers sent by the cover guiding mechanism and sends the covers into the spot welding stations, a laser spot welding mechanism which welds the cell covers and cell polar ears sent into the welding stations, and a control system which can control the motion of various mechanisms, wherein the cover feeding mechanism and the cover guiding mechanism are in matched connection and arranged above the cell feeding mechanism, so that the covers contact upper polar ears of the cells; the laser spot welding mechanism is positioned aside the cell feeding mechanism; and a laser emitting center of the laser spot welding mechanism is in the same line with the contact points of the covers and the upper polar ears of the cells. The invention provides a laser spot welding processing apparatus which can automatically send the cylindrical cells and the covers into the welding stations and perform spot welding connection on the upper polar ears of the cells and the covers.

Description

【Technical field】 [0001] The invention relates to the field of battery processing, in particular to processing equipment capable of automatically welding and connecting a cap and tabs during the processing of lithium-ion batteries. 【Background technique】 [0002] Lithium-ion battery is a large-capacity, high-power battery with excellent performance such as high working voltage, high specific energy, long cycle life, low self-discharge rate, no memory effect and no pollution, so it has been realized in just a few years Large-scale industrialization has been widely used in mobile phones, notebook computers and consumer electronics appliances, etc., and has attracted great attention from the world's scientific and technological circles and industrial circles. The 18650 lithium-ion cylindrical battery generally includes a casing and a cap, and the casing contains an electrolyte and a battery core wound by positive and negative electrode sheets and separator paper. In the proces...
