Operation principle：

Feeding manipulator 2 by with lithium cell pallet crawl, be delivered to feeding station platform, etc. other processes all complete it Afterwards, the pallet on all stations is jacked up and is detached from workbench by the lifting body set up on conveying mechanism 1；Conveying mechanism 1 will be held in the palm Disk is delivered to above the platform of next station, and lifting body declines, and pallet is placed on workbench, is set up on conveying mechanism 1 Clamp pressing battery core, later as each process mechanism carry out each process operation；

It is anode prewelding process after upper material process, major function is welding protection piece, bonding machine on positive pole ear Structure is built up in its material fetching mechanism on same displacement mechanism, in welding mechanism moving process, the agent structure of material fetching mechanism Do identical displacement；

The implementation of prewelding is：Screening glass is delivered to prewelding station by the feeding manipulator 2 of feeding, on welding mechanism Clamp pressing fixes screening glass and anode, carries out the welding of first solder joint later；After completing first solder joint, welding fixture It opens, welding mechanism is moved to second and third in battery core width direction ... is welded the position of a solder joint.Welding mechanism moves During dynamic, the feeding manipulator 2 of material fetching mechanism does the movement of negative direction in the same time, keeps screening glass and battery core anode phase To static, when avoiding the movement of material fetching mechanism main body, screening glass movement driven, damages the screening glass welded and battery core.

Anode prewelding is similar with function with the structure of cathode prewelding, and the position for differing only in welding is different.

Trimming process is carried out after prewelding, and major function is extra lug to be cut off using cutter, is ensured certain Length.

It is welded after trimming process for TAB, TAB is welded with main weldering with adding Hu Hanliangge mechanisms, and the additional function that the two combines is The welding procedure for the adjacent welds that are staggered, the superfluous product of heat that the continuous welded bands of adjacent welds is avoided, influences welding effect.

TAB welded structures, action are similar with prewelding, weld the required copper welded difference lies in TAB, aluminium flake compares screening glass Greatly.

It is flattening mechanism 10 after TAB welderings, mainly moved up and down the lug for compressing and welding TAB using upper and lower two pressing plates It flattens, convenient for subsequent rubberizing process.

After leveling, adhesive tape rubberizing mechanism respectively pastes last layer gel up and down in anode, cathode weld, to protect lug.

After rubberizing, the gel posted using upper and lower two pressing plates is flattened, fastened by compressing glue mechanism 14.

It is mechanism for testing 15 after rubberizing, mainly using the voltage internal resistance between probe measurement positive and negative anodes, detects battery core Whether there is phenomena such as short circuit between positive and negative anodes, so as to judge the qualification of welding effect and product, if product is qualified, battery core Battery core at crawl and is delivered to the material flow line of lower road technique by blanking mechanical hand 16 from pallet, and pallet blanking mechanical hand 17 will be empty Pallet is delivered to corresponding material flow line；If product is unqualified, battery core blanking mechanical hand 16 by battery core from pallet at crawl simultaneously It is delivered on NG platforms, later the battery core of artificial treatment NG, empty pallet is delivered to corresponding logistics by pallet blanking mechanical hand 17 Line.

The utility model fully-automatic supersonic welding equipment can realize the work(such as automatic loading/unloading, TAB welding, rubberizing, test Energy.

Due to this equipment processing the remote ultra-traditional of lithium cell specification lithium cell specification, according to manipulator capture conveying Mode will lead to the generations of the good factors such as device structure complexity, bulky dimensions, also can be because of large capacity soft-packaging lithium battery cores in itself Structure and the factors such as quality there is phenomena such as lithium cell bending, deformation, closed so as to influence the production efficiency of lithium cell and product Lattice rate etc..

The design mainly researches and develops the welding manner using ultrasonic bonding；With using lithium cell pallet as carrier, lithium cell The feeding style integrally conveyed with pallet；Nested design method is combined with fixture 12 using conveying mechanism 1.Each mechanism of the design Front be designed with corresponding workbench, the realization of each process function is completed on corresponding workbench.When institute is organic After structure all completes its process function, conveying mechanism 1 is unified to be delivered to next process by the product on each mechanism workbench.

The preferable specific embodiment of the above, only the utility model, but the scope of protection of the utility model is not This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, according to this practicality Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
