The workpiece is stationary, and the laser head system moves along
the X, Y and Z axes. The repeated positioning accuracy is ≤±0.05mm.
With welding parameter storage module, it is convenient to quickly
call the parameters of different products or to adjust and store
the process parameters. The storage quantity is required to be ≥5
groups.
11. The welding shall be based on the inner surface of the top
cover pole column, to avoid abnormal defocusing due to the
thickness difference of incoming materials, resulting in poor
welding. At the same time, the distance measurement function is
required to monitor the change of focal length.
The length of optical fiber does not exceed 20 meters.
Rubberizing module
1. After the completion of laser welding, apply 1 piece of high
temperature protective tape to the positive and negative laser
welding spots respectively; After the core is closed, tape is
pasted on the tail and side of the cell

Cover plate feeding mechanism mainly includes feeding cart, cover
plate tray, pallet lifting mechanism, empty tray transfer
mechanism, gantry feeding manipulator. The main realization of the
cover plate after the material will be manually unpack the cover
plate into the tray, through the cart to the feeding mechanism
feeding level, the manipulator will automatically take the cover
plate, empty tray back to the cart, put the full plate after the
cart will be manually pulled away.
The encoder is mainly composed of encoder, encoder adjustment
mechanism, dust removal mechanism, cover clamp and rotary cylinder.
It mainly realizes the two-dimensional code engraving on the pole
cylinder of the cover plate, and then after the code is engraved,
the code is then scanned to bind the information of the cover plate
to the two-dimensional code, and the two-dimensional code
information is uploaded to the system for easy recording and
reading; The dust from the coding process is collected by the dust
removal system.
The secondary positioning mechanism of the electric cell is mainly
composed of a bracket and a three-sided regulating mechanism. It
mainly realizes the adjustment of the distance between the electric
cells completed by ultrasonic welding to meet the distance
requirements for the welding of the adapter plate. The short side
of the electric cells is reversed and aligned in the center through
the cylinder. The length direction is based on the positioning
reference of the polar ear end position, and the other side of the
cylinder is adjusted to meet the requirements for the distance
between the electric cells.
3.3.4 welding station
The welding station is mainly composed of welding triaxial linear
module, laser welding joint, coaxial smoking pipe and flattening
protection mechanism. It mainly realizes the laser welding of the
adapter. The flattening mechanism before welding compacts the
adapter and the cover plate, drives the welding joint to move
through the triaxial linear module, and the dust removal system
simultaneously smokes and dust removal through the coaxial smoking
pipe. Specific dust removal protection measures are as follows:
The pressure mechanism closely fits the adapter with the cylinder
surface of the top cover through the cover plate, and the pressure
head of the cover plate has a spring flexible mechanism, so that
the positive and negative adapter and the pole column can be
compressed even if they are not in the same plane. The welding
shield encloses the welding joint movement area and covers the cell
surface. The welding slag and spatter generated in the welding
process are separated from the cell and the top cover to prevent
the slag and spatter from falling out.
There are dust removal pipes at both ends of the welding press
plate, which are connected to the smoke purifier. The welding head
is also equipped with coaxial smoking pipe. In the welding process,
three smoking pipes are used to remove dust and smoke at the same
time to ensure that welding slag and smoke can be removed in time.
