Embodiment

[0033] Such as figure 1 with figure 2 Commonly shown is a schematic structural diagram of a fully automatic tab welding device of the present invention, which is only a part of the battery processing equipment and should be used in conjunction with other components in actual use. Other components are not shown here, only This device will be described.

[0034] The fully automatic lug welding device firstly includes a machine base 1, on which a guide rail 2 is vertically arranged, on which a positioning mechanism for positioning the electric core 3 is provided, specifically:

[0035] The positioning mechanism includes a cell positioning block 61 fixed on the guide rail 2. By placing the cell 3 on the cell positioning block 61, it can be fixed in its radial direction, and at the same time, the cell 3 can be moved up and down in its axial direction. move. There is also a welding needle guide plate 62 slidably arranged on the guide rail 2 above the electric core 3, which is dr...

Abstract

The invention provides a full automatic tab welding device, which is used for solving the problems of poor welding quality and low production efficiency of a cathode tab in the prior art. The full automatic tab welding device comprises an engine base, and further comprises an actuating mechanism, wherein guide rails are vertically arranged on the engine base, and a positioning mechanism used for positioning a battery cell is arranged on the guide rails; the actuating mechanism comprises an upper welding electrode movably arranged at the upper parts of the guide rails and a lower welding electrode moveably arranged at the lower parts of the guide rails, and a following mechanism is used for controlling the motion of the upper welding electrode is arranged on the upper welding electrode. The device realizes full automatic mechanization of welding process of the tab during the production technology of cylindrical batteries, saves manpower, greatly improves both production efficiency and welding quality of batteries, is convenient to maintain, is artistic in structure, is accurate in location, is reliable for welding and has multiple functions.

Description

technical field [0001] The invention relates to the technical field of battery processing equipment, in particular to a device capable of fully automatic welding of cylindrical battery negative pole tabs. Background technique [0002] The tab is a raw material for lithium-ion polymer battery products. It is a metal conductor that leads the positive and negative electrodes out of the battery. In layman's terms, the tab is the ear of the positive and negative poles of the battery, which is used for charging and discharging. When the contact point, the negative tab is also called the bottom tab. [0003] At present, in the production process of cylindrical batteries, the tabs need to be welded. However, because the negative tab of the battery cell is located at the bottom of the inside of the battery cell, when welding, the soldering needle needs to pass through the center hole of the battery coil to touch the negative tab before welding. At this time, the battery shell and th...
