Detailed Description
Referring to fig. 1 and 2, fig. 1 and 2 disclose a method for coating an electrode material using an extrusion coating head with a programmable flow-control valve controlled by a control module;
the method comprises the following steps:
s1, the control module controlling the throughput valve to perform a material-regurgitation operation at a thick portion and a material-regurgitation operation at a thin portion according to a predetermined data on a change rule of a coating thickness of the electrode sheet in a longitudinal direction during one cycle;
s2, the throughput valve being configured to return to a starting level on a level of a throughput of the throughput valve being zero on a same cycle of electrode chip coating;
as shown in fig. 3 and 4, the dashed line in fig. 3 is the designed electrode material thickness 32, the material belt advances along the arrow 30 direction, when the coating is started, a convex strip 31 along the transverse direction is formed at the starting end for various reasons, the industry is commonly called the head thickness, the longitudinal section of the convex strip 31 is in the shape of a circular arc, and the material throughput of the exhaust valve is equal to the product of the area of the longitudinal section of the convex strip 31 multiplied by the length of the transverse direction; for accurate performance of the data-reception, the rib 31 may be divided into a plurality of segments 311, as shown in fig. 4, wherein the control module controls a flow-control valve to gradually divide the data-reception for each segment 311; after the material collection is completed, the material is slowly and evenly regurgitated to the electrode segments behind the raised strips 31, so that the thickness of the electrode material of the following electrode segments is basically equal to the designed thickness 32 of the electrode material (through experiments, because slow and even regurgitation is adopted, the thickness of the electrode material of the following electrode segments is basically equal to the designed thickness 32 of the electrode material, the design requirement can be met), and the measurement piston of the material collection valve returns to the start position after the material collection is completed, so that the next smoking action can be facilitated; in summary, in this step, when only one rib 31 is present during coating, a material-gating operation is performed on the rib 31, followed by a gradual and even feedback of the material to the electrode segments following the rib 31, and finally a returning of the metering piston of the gating valve to the start position.
Referring to fig. 5 and 6, fig. 5 and 6 disclose that during the coating process, both the rib 31 may be present, and the first groove 33 and the second groove 34 may be present, wherein the rib 31 may require a throughput V0, the first groove 33 may be a first throughput V1 requiring throughput, and the second groove 34 may be a second throughput V2 requiring throughput (of course, the throughput V0 may be plural, or one or more throughput may be possible). In the present invention, only one rib 31 and two grooves are used to describe the relationship between the throughput and the throughput of the present invention. As shown in fig. 5 and 6, in the present embodiment, the rib 31 may correspond to a throughput V0 equal to the sum of a first throughput V1 and a second throughput V2, and when coated, the rib 31 may extend into a corresponding electrode material according to the electrode length occupied by the rib 31, and when the electrode is coated with respect to the first groove 33, the rib may discharge the first throughput V1 to fill the first groove 33 with the designed electrode material thickness 32; when the electrode is coated on the opposing second groove 34, the valve may output a second output V2 to fill the second groove 34 to the design electrode material thickness 32, and finally, the metering piston of the valve may revert to the starting position. The above-described method is suitable for a capacity V0 equal to the throughput, i.e., a capacity V0 as the throughput, and finally, a metering piston of the throughput valve is configured to revert to an initial position.
While the above analysis shows that the throughput V0 is equal to the sum of the first throughput V1 and the second throughput V2, the present invention is also suitable for throughput V0 which is greater than the sum of the first throughput V1 and the second throughput V2; or the throughput V0 is less than the sum of the first throughput V1 and the second throughput V2.
When the throughput V0 is greater than the sum of the first throughput V1 and the second throughput V2, the excess throughput V0 minus the sum of the first throughput V1 and the second throughput V2 may be evenly distributed over a length of the electrode minus the throughput V0, a length of the first throughput V1 and a length of the electrode remaining after the throughput V2, and finally the metering piston of the metering valve may be returned to the start position; the method is suitable for situations where the throughput V0 is greater than the throughput. I.e. the difference between the throughput and the throughput is evenly distributed over the entire electrode length minus the throughput V0, the remaining electrode length after the throughput, and finally the metering piston of the throughput valve is returned to its start position.
When the throughput V0 is less than the sum of the first throughput V1 and the second throughput V2, the throughput of the sum of the first throughput V1 and the second throughput V2 minus the throughput V0 may be averaged over the entire electrode length minus the throughput V0, over a length corresponding to the first throughput V1 and over a remaining electrode length following the length corresponding to the second throughput V2, and finally the metering piston of the metering valve may revert to the start position; the method is suitable for a capacity of throughput V0 being smaller than capacity, i.e. the capacity of throughput less the capacity is measured, and the capacity of the metering piston is averaged over the entire electrode length minus the capacity V0 and the remaining electrode length over the capacity corresponding to the capacity, and finally the capacity is returned to the start position.
S3, stopping coating at a preset distance to form a blank belt;
s4, repeating the steps S1-S3 to coat the electrode material in the next period;

and S102, corresponding each thickness detection point to the detected thickness data one by one, establishing data of the coating thickness change rule of the electrode plate in the longitudinal direction, and storing for later use.
The invention also provides a precise program-controlled coating and feeding abruption and discharge valve, which comprises a valve body 1, a linear driving device 2, a metering piston 3 and a control module 4, wherein the metering piston 3 and the control module 4 are arranged in the valve body 1 and driven by the linear driving device 2, the control module 4 is electrically connected with the linear driving device 2, and the control module 4 controls the abruption and discharge valve to perform material regurgitation at a thick part and material spitting at a thin part according to the data of the coating thickness change rule of an electrode slice in one period measured in advance in the longitudinal direction; the channel may have a zero difference between a throughput and a throughput of the channel during a same cycle of electrode sheet coating.
