Problems solved by technology
[0004] However, in the existing electric core assembly process, usually a single electric core is directly welded to the cover plate connecting piece, or a single electric core is divided into two electric cores or multiple electric cores are respectively welded to the connecting piece (so-called butterfly welding ), due to the current industry development, the requirements for gram capacity, cruising mileage, cycle period, life, battery pack energy ratio and safety are getting higher and higher. In order to meet the above requirements, the battery energy has been enlarged, but the battery The larger the energy of the cell, the more the number of layers of the battery, and the more the number of layers, the single cell cannot be ultrasonically welded at one time, so the cells are divided into two or more and combined for welding. The quality of production plays an incomparable key role

The invention belongs to the technical field of battery production equipment, and particularly relates to an ultrasonic welding tool which comprises a three-dimensional rack and a battery cell jig. The three-dimensional rack comprises a first azimuth table, a second azimuth table and a third azimuth table, wherein the first azimuth table is installed on a working table, and a first moving mechanism for controlling the first azimuth table to translate in a reciprocating manner in the first azimuth is arranged; the second azimuth table is mounted above the first azimuth table, and a second moving mechanism for controlling the second azimuth table to translate in a reciprocating manner in the second azimuth is arranged; and a limiting mechanism is arranged at the top of the third azimuth table, and the battery cell jig is mounted on the third azimuth table through the limiting mechanism. According to the ultrasonic welding tool, the three-dimensional rack comprises a horizontal movement mechanism and a vertical movement mechanism, and the movement in the three-dimensional azimuth enables the battery cell jig on the three-dimensional rack to freely move in the three-dimensional space to form multi-dimensional movement so as to meet the ultrasonic welding requirement, so that the welding quality of the battery cell is improved.
Description
technical field [0001] The invention belongs to the technical field of battery production equipment, in particular to an ultrasonic welding tool. Background technique [0002] The main core components of the aluminum shell battery include the battery cell, the aluminum shell, the cover plate, the electrolyte, the connecting piece, the PET film, the adhesive tape, etc. The performance and safety of the battery cell are self-evident, and the assembly quality of the battery cell directly It determines battery safety, electrical performance (capacity, energy, internal resistance, etc.) and electrochemical reaction. The assembly method of the cell mainly directly affects the quality of pole piece assembly, ultrasonic welding quality, laser welding quality and related raw material quality decisions. [0003] Compared with the quality of ultrasonic welding, the current ultrasonic welding machines made of lithium batteries are basically imported ultrasonic welding machines. At prese...
