The traditional ceramic substrate forming mode comprises dry press forming, film rolling forming and hot die casting forming. The main problems of these molding methods are small production, poor thickness uniformity, unstable shrinkage, poor surface finish, etc., and particularly when producing substrates of 1mm or less, these methods have failed. In the beginning of the year 90 of the 20 th century, a production line for producing ceramic substrates by a casting machine is introduced successively. The casting machine is a forming device for preparing the slurry into a sheet film strip with uniform thickness and specific width, and is widely applied to film strip production in the fields of electronic components, electronic materials, magnetic materials, special ceramics and the like. Because the casting forming has the advantages of large yield, good thickness consistency, stable shrinkage, high surface smoothness and the like, the ceramic substrate produced by the casting forming rapidly replaces the substrate produced by dry press forming, film rolling forming and hot-press casting forming.
When the aluminum nitride ceramic substrate is processed by adopting a casting method, components such as a solvent, a dispersing agent, a binder, a plasticizer and the like are generally added into ceramic powder, ball milling is carried out to obtain stable and uniform ceramic slurry, the ceramic slurry is subjected to defoamation treatment and then is cast on a casting machine, a layer of raw ceramic chips is formed after drying, the raw ceramic chips are cut according to the required size, and then the ceramic chips are subjected to glue discharging and sintering to obtain ceramic sheets. Because of the need of the aluminum nitride ceramic manufacturing process, a casting film belt is needed in casting by a casting machine, and the casting film belt receives a belt-shaped object of casting slurry in the casting process for matching with the shaping of raw ceramic chips.
However, sundries such as green brick slag, dust and greasy dirt are adhered to the casting film belt in the use process, and as the production time increases, excessive dust and raw material particles accumulated on the surface of the casting film belt can cause deformation and uneven surface of the casting film belt during winding, so that the formation of green ceramic chips can be damaged, the local thickness of the green ceramic chips is reduced, and the production quality of the green ceramic chips is reduced. The current solution is: the casting machine is characterized in that the casting film strip can be wound at the tail part of the casting machine after each casting production, a worker moves the casting film strip wound at the tail part of the casting machine to a cleaning mechanism for cleaning, and as the casting film strip used in the casting production process can be wound at the tail part of the casting machine after each casting production, sundries such as slag, dust and greasy dirt are adhered to the casting film strip in the winding process, the casting film strip can be deformed, even if the casting film strip is cleaned, the casting film strip can only be prevented from being deformed further, the deformation of the casting film strip cannot be prevented from the source, the surface of the casting film strip can be uneven, the forming of raw ceramic chips can be damaged, the local thickness of the raw ceramic chips is reduced, and the production quality of the raw ceramic chips is reduced. Meanwhile, the casting film belt can be rolled at the tail of the casting machine after each casting production, sundries such as slag, dust and greasy dirt which are adhered to the casting film belt can be pressed in the rolling process, so that the sundries such as slag, dust and greasy dirt are adhered to the casting film belt more firmly, the cleaning difficulty is increased, and the casting film belt is difficult to clean through a cleaning mechanism.
