As shown in fig. 1 and fig. 3, a coating apparatus 100 according to an embodiment of the present invention includes a conveying structure, a first coating assembly 20, and a second coating assembly 30.
The transport structure is used to transport the substrate 200.
The first coating component 20 and the second coating component 30 are arranged on the same side of the conveying structure, and the first coating component 20 and the second coating component 30 are arranged along the length direction of the substrate 200, the first coating component 20 is used for coating on one side surface of the substrate 200 to form a first coating 201, and the second coating component 30 is used for coating on one side surface of the substrate 200 to form a second coating 202.
Wherein the first coating unit 20 and the second coating unit 30 alternately operate to form a plurality of first coating layers 201 and a plurality of second coating layers 202 on one side surface of the substrate 200, and the plurality of first coating layers 201 and the plurality of second coating layers 202 are alternately arranged at intervals along the length direction of the substrate 200.
It should be noted that the distance between any adjacent first coating 201 and second coating 202 is the same.
By providing the coating apparatus described above, the first coating unit 20 and the second coating unit 30 alternately operate to form a plurality of first coating layers 201 and a plurality of second coating layers 202 alternately arranged at intervals on one side surface of the substrate 200. Because the first coating assembly 20 and the second coating assembly 30 run alternately, the start-stop speed requirements of the first coating assembly and the second coating assembly are low, the coating can be rapidly carried out, and the production efficiency is high.
It should be explained in conjunction with fig. 3 that the shaded area is the coating layer, and the area between two adjacent coating layers is the blank area 203, assuming that the distance between two adjacent coating layers is l1And the distance between two adjacent blank regions 203 is l2Also assume that the coating assembly is shut down at the fastest speed and then started, with the time interval between shut down and start up being t.
In addition, it should be noted that the designations of the a-coating, the c-coating, and the e-coating, and the b-region and the d-region in fig. 3 are used to facilitate the explanation below.
In an ideal situation, taking the coating a, the coating b and the coating c as an example, the coating assembly stops coating at the position of the boundary between the coating a and the coating b after being stopped, then starts coating at the position of the boundary between the coating b and the coating c after being started, and the above steps are repeated in a circulating mode.
When coating is performed using the existing single coating unit, the coating unit needs to be stopped at the b-zone, where the maximum transport speed v of the substrate 200 is1＝l1/t。
When the coating is alternately performed using the first coating unit 20 and the second coating unit 30, the a-coat and the e-coat are applied by the first coating unit 20, the c-coat is applied by the second coating unit 30, the first coating unit 20 is stopped after the application of the a-coat is completed, the c-coat is applied by the second coating unit 30, and the first coating unit 20 is started at the boundary between the d-zone and the e-coat, when the maximum conveyance speed v of the substrate 200 is set to be v2＝(2*l1+l2)/t。
Therefore, it can be determined without any doubt that the first coating unit 20 and the second coating unit 30 alternately operate to effectively increase the coating speed and thus the production efficiency on the premise of satisfying the coating effect.
When the substrate 200 is not conveyed at the theoretical highest speed, the start-stop speed of the first coating assembly 20 and the second coating assembly 30 can be controlled while the production efficiency is increased, and the first coating assembly 20 and the second coating assembly 30 do not need to act at the fastest start-stop speed, so that the damage to the structures of the first coating assembly 20 and the second coating assembly 30 caused by the excessively fast start-stop speed and the influence on the service life of the first coating assembly 20 and the second coating assembly 30 are avoided.
In addition, the first coating assembly 20 and the second coating assembly 30 can be prevented from being stopped due to inertia after the first coating assembly 20 and the second coating assembly 30 are stopped, and the coating is prevented from being gushed out when the coating is restarted to influence the thicknesses of the first coating 201 and the second coating 202, namely, the initial positions of the first coating 201 and the second coating 202 are prevented from being too thick.
