Further, the battery cell detection assembly is connected with the control system; the control system is connected with the flow line body. Through electric core test component, can screen out unqualified electric core to carry out the stepping to qualified electric core. And the classified battery cores are conveyed to the next procedure through a flowing line body.
Specifically, in this application, the setting of electricity core detection subassembly is in the leading of the mobile line body end of entrying, can be used for detecting voltage, internal resistance and the outward appearance size etc. of electric core, consequently, in this application, the stepping can be carried out the stepping according to electric core voltage, outward appearance size etc..
For example, when the streamlined body is provided with five gears, when the cell voltage is 20v-21v, the gear is 1 gear; when the cell voltage is 21v-22v, the cell voltage is in 2 gears; when the thickness of the detection battery core is 50-50.5 millimeters, the detection battery core is in a 3-gear position; when the thickness of the detection battery cell is 50.5-51.0 mm, the detection battery cell is in 4 gear; and when the cell voltage is greater than 30v or 0, the cell is in an unqualified gear (namely 5 gears), and the cell is an unqualified cell. The structure of this application is at the during operation, the lithium cell electric core of accomplishing last process is through transmitting to the production line of this application, detect through electric core detecting component earlier and carry detection data to control system in, judge and screen out unqualified electric core and make it flow away from unqualified gear by control system, carry out the stepping to qualified electric core through control system simultaneously, electric core after the stepping passes through the direction gear and gets into the end of entrying of the flow line body, carry to next process through each flow line body. The qualified electric core of transfer machinery hand (hold) grabs the rubber coating station and carries out the rubber coating after the in-process that the electric core after stepping carried on the flow line body, puts back the production line of this application and carries to next process.
This application is through setting up the slip gang pulley on the flow line body, set up on the flow line body and block the subassembly, then through the tensioning degree of the slip gang pulley of tensioning structure control, can be under the prerequisite that does not influence lithium cell electricity core transmission on the logistics line, guarantee that electric core does not lean forward or pitch backward, reduce the phenomenon of reversing when inertia stops, do not have because of influences such as vibrations and bulge position in transportation process, can effectively prevent the scotch on electric core surface. Moreover, through setting up independent cylinder that blocks, can make certain mobile line body block the during operation, do not influence the electric core of other mobile line bodies and flow, adjust the convenience, can compatible various size and dimension's electric core stepping and transmission.
