The roller driving device 52 and the pressing driving device 41 both adopt air cylinders, and the roller driving device and the pressing driving device are all existing, are directly purchased from the market and are provided with position sensors.
The roller driving device 52, the photoelectric sensor 449, the pressing driving device 41, the third motor, the second motor, the first motor and the position sensors are all connected to the PLC.
Each position sensor is preset, and thus the stroke of each driving device is preset.
And then presetting processing stations of the conveying device 500 during bending and rolling.
The movement locus of the roll-flattening process of the roll-flattening device 100 is preset. The rolling processing programs of the different battery modules 200 are set and stored in the PLC in advance. When the rolling motion track is preset, the plunger 445 is adjusted as required, and the pressing piece 43 is adjusted to a desired state.
In production, the tabs 202 are mounted in the mounting grooves 201 of the battery modules 200, the battery modules are placed on the tray 300, and the conveyor 500 conveys the tray 300 to a predetermined position, thereby conveying the battery modules 200 to a predetermined processing position. And bending the tabs, and after the tabs are bent, conveying the battery module 200 to a preset rolling and flattening station by using the conveying device 500 to perform rolling and flattening operation.
Before rolling, the code scanning device 6 scans the bar code or the two-dimensional code on the code battery module 200, and then feeds the acquired information back to the PLC, and the PLC calls the corresponding rolling processing program.
When rolling, the PLC controls the first motor, the second motor and the third motor to work, and adjusts the pressing piece 43 and the roller 51 to reach a preset position, which is named as coarse positioning; the pressing end surface of the pressing piece 43 and the bending side surface of the tab 202 in the mounting groove 201 are positioned in the same plane; the roller 51 is opposite to the other bent side face of the tab 202, and is close to the root of the bending, namely the bending angle;
then, the PLC controls the piston rod of the pressing driving device 41 to extend out to a predetermined position along the X-axis direction, so that the pressing piece 43 presses the tab 202; at this time, the method is named as fine positioning;
then, the PLC controls the piston rod of the roller driving device 52 to extend along the X-axis direction to a predetermined position, so that the roller 51 presses the other side surface of the tab bend; at this time, the method is named as fine positioning;
and then, the PLC controls a second motor 36 of the Z-axis servo sliding table to work, and drives the first rolling part 5 to move up and down for rolling.
After the completion, each driving device resets and waits for the processing of the next tab.
Flattening the special-shaped tab:
the processing procedure is also preset before production.
The PLC controls the first motor, the second motor and the third motor to work, adjusts the pressing piece 43 and the roller 51 to reach a preset position, and performs coarse positioning; at the moment, the upper surface and the lower surface of the front end of the profiling flattening piece 71 are opposite to the two surfaces to be flattened of the lug; in specific implementation, the shapes and sizes of the upper surface and the lower surface of the front end of the profiling flattening piece 71 are the same as the design sizes and shapes of the two surfaces to be flattened of the tab;
and then the PLC controls a first motor of the X-axis servo sliding table 2 to work, drives the profiling flattening piece 71 to move along the X-axis direction, reaches a preset position, compresses two surfaces to be flattened of the lug 202, keeps a certain time, and then resets to finish processing to flatten the next special-shaped lug.
Although specific embodiments of the present invention have been described, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the claims appended hereto.
