Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present invention, "a plurality" means two or more unless specifically limited otherwise.
The inventors have found that the precision and stability of the knife-edge gap are factors affecting the precision of the film thickness in the precision range of 1 to 10 μm in the cast film thickness. The adjusting mode in the prior art is difficult to be suitable for the precision interval of the casting film thickness of 1-10 mu m, and has the disadvantages that the debugging difficulty is high after the first assembling debugging and the knife grinding, and the precision is difficult to ensure; on the other hand, the precision is reduced due to the micro deformation of the tool rest in the long-term working process. Therefore, the embodiment of the application provides a high-precision doctor blade casting knife, so that the integral range of the width of a knife edge gap can be accurately adjusted to be within 2 mu m.
Example one
As shown in fig. 1 and 3, the high-precision doctor blade casting knife assembly comprises a knife body 5 and a knife rest 6, wherein the knife body 5 is fixedly connected to the knife rest 6, and knife rest assembly reference bosses (15, 16 and 17) are arranged on the back surface of the knife rest 6.
As shown in fig. 2, the cutter body 5 is fixedly connected to the cutter holder by a set of cutter body fixing bolts 9, and the front and back (front view direction) of the cutter body 5 is referred to as longitudinal direction, the up and down (top view direction) is referred to as vertical direction, and the left and right (side view direction) is referred to as horizontal direction. The high-precision scraping and coating type tape casting cutter assembly further comprises a cutter body vertical adjusting mechanism and a cutter body longitudinal adjusting mechanism, wherein the cutter body vertical adjusting mechanism comprises a plurality of vertical adjusting bolt-nut assemblies (7, 8) which are respectively arranged at the top of the cutter frame 6 so as to vertically press the cutter body 5 and enable the cutter body to generate local micro-deformation in the vertical direction; the cutter body longitudinal adjusting mechanism comprises a plurality of longitudinal adjusting bolt-nut assemblies (10, 11) which are respectively arranged in front of the cutter frame 6 so as to press the cutter body 5 along the longitudinal direction and make the cutter body generate local micro-deformation along the longitudinal direction. In the scraping and coating type tape casting knife in the prior art, the knife body and the knife rest are connected and then lack of adjusting function. The assembly precision adjustment of the casting knife and the casting shaft is pressed and extruded by hands, the adjustment difficulty is high, the adjustable precision is low, and the assembly precision can be further reduced along with the long-term release of the internal stress of the knife body. In this embodiment, on the basis of the dimensional accuracy of the blade body 5, the vertical adjusting mechanism and the longitudinal adjusting mechanism can be pressed against each other to cause a local micro-deformation of the corresponding portion of the blade body 5, so as to improve the assembly accuracy of the blade edge 18 of the blade body 5 and the casting shaft 1, for example, the overall range can be accurately adjusted to within 2 μm. The local micro-deformation can be vertical local adjustment, longitudinal local adjustment, or vertical local adjustment and longitudinal local adjustment which are carried out synchronously. The vertical adjusting bolt-nut assemblies (7, 8) can be arranged in two or more than two according to the requirement of adjusting precision and are generally uniformly arranged along the length direction of the tool rest 6, and the longitudinal adjusting bolt-nut assemblies (10, 11) can be arranged in two or more than two according to the requirement of adjusting precision and are generally uniformly arranged along the length direction of the tool rest 6.
The cutter body 5 is preferably designed into a vertically symmetrical double-edge structure, and the two edges 18 are respectively arranged at the upper end part and the lower end part of the cutter body 5, so that the structure has the advantages that when one edge is influenced by abrasion, damage and the like to produce, the other edge can be quickly replaced, and the great influence on the productivity is avoided. In addition, the cutter body 5 is made of non-magnetic tungsten steel at least at the edge part. The knife edge is made of non-magnetic tungsten steel, so that the cost and the processing difficulty can be reduced, the service life is prolonged, and the magnetic influence is eliminated. In the prior art, the cutter body made of the integral stainless steel material has the advantages of long service life, good processability and the like, but the remanence is difficult to completely eliminate, and the influence on ferrite slurry is difficult to avoid.
As shown in figures 2 and 3, the tool rest 6 adopts a uniform-section beam or a similar uniform-section beam structure, and preferably three tool rest assembly reference bosses (15, 16 and 17) are respectively arranged at the left end, the right end and the middle part of the back surface of the tool rest. In addition, the knife rest 6 is also provided with a handle 12 for holding and dismounting. The number of the handles 12 is preferably two, and the handles are respectively provided at the left and right ends of the front surface of the blade holder 6.
As shown in fig. 1, 2 and 4, the present embodiment further includes a blade cover 14 connected to the blade holder 6 by a blade cover fastening bolt 13, a fluid guide structure capable of stabilizing a flow state of the casting slurry is provided at a lower end of the blade cover 14, and the blade cover 14 is provided in front of the blade body 6. The fluid guide structure is a slope structure 19 arranged at the lower end of the knife cover 14, the slope structure 19 is in an inclined plane shape or an inclined arc surface shape, the cross section area of the casting slurry flowing through the knife cover 14 can be gradually reduced, the lowest end of the casting slurry is aligned with the knife edge 18, and the structure can avoid the phenomena of laminar flow disorder and the like caused by abrupt change of the cross section area of the fluid, so that slurry agglomeration is inhibited. The slope structure 19 is preferably integrated with the knife cover 14, or may be separate and connected to each other. In the scraping type casting knife in the prior art, when the casting slurry flows along with the carrier film and passes through the knife edge gap, the cross section area of the casting slurry suddenly changes at the knife edge, the flow velocity of the casting slurry is reduced in a broken manner at the knife edge, so that the laminar state of the casting slurry at the knife edge is damaged, the agglomeration is easy to occur, and the film thickness uniformity of the casting film is greatly influenced.
Example two
A casting machine, as shown in fig. 5, comprises a casting machine body, a casting knife assembly, a casting shaft 1, a material box 2 for containing casting slurry and a bearing film 4 for forming a slurry film. The carrier film 4 is driven at a constant speed along the casting direction at a certain linear speed along with the rotation of the casting shaft 1.
The casting knife assembly is a high-precision scraping type casting knife assembly as described in the first embodiment, and is assembled on the casting machine body through the knife rest assembling reference bosses (15, 16, 17). The length direction of the cutter body 5 is parallel to the axial direction of the casting shaft 1, and a preset cutter edge gap is formed between the cutter edge 18 of the cutter body 5 and the bearing film 4. The carrier film 4 is attached to the surface of the casting shaft 1 and is transported as the casting shaft 1 rotates.
The embodiment preferably further comprises a hot air drying part for timely and uniformly drying the slurry film on the carrier film 4.
When the casting machine works, stable liquid level height is formed between the material box 2 and the knife cover 14 by casting slurry, and after the casting slurry passes through the knife edge gap, a slurry film with uniform thickness is formed on the bearing film 4. The thickness control of the slurry film is mainly realized by changing the width of the knife edge gap, and specifically comprises the following steps: t = h δ; in the formula, t is the thickness of the slurry film after drying, h is the knife edge gap, and delta is the shrinkage rate of the slurry after drying, and the specific values are selected according to the formula of the casting slurry.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages: the problem that the thickness of a casting film is unstable in the blade coating type casting process can be solved, the whole range of the knife edge gap can be accurately adjusted to be within 2 mu m, so that the current high-precision requirement on a mechanism is met, the implementation mode is simple and reliable, and the cost is low.
