Problems solved by technology

[0010] However, in the conventional roller coating device shown in Patent Document 1, the bottom of the accommodating space is basically a flat bottom or an inclined plane or curved surface. In the case of a small shape, there is a phenomenon that the objects to be processed tend to stick to each other
[0011] In addition, if a film with a relatively thin thickness is to be formed, the adhesion amount of the coating treatment agent to the surface of each object to be treated is not uniform, and it is difficult to form a uniform thickness.

no. 1 Embodiment approach

[0043] The first embodiment is as figure 1 with figure 2 As illustrated: it is characterized in that,

[0044] The roll coating device 20 is provided with: a rotating unit 27, which has an accommodating space 25 and rotates around a rotating shaft (L) inclined at a predetermined angle relative to the horizontal direction;

[0045] The accommodating unit 29 is formed of a mesh material and has a cylindrical portion 29a and a bottom 29b, and is installed in the accommodating space 25 so that the central portion of the bottom 29b coincides with the rotation axis (L), and accommodates a plurality of Rotate together with the rotating unit 27 in the state of the processed object 10;

[0046] a spraying unit 31, which sprays a coating treatment liquid 31a containing a coating component to a plurality of objects to be treated flowing inside the accommodation unit 29;

[0047] The heating unit 35 is configured to heat the plurality of processed objects flowing inside the housing u...

no. 2 Embodiment approach

[0151] A second embodiment is a roll coating method for coating the surfaces of a plurality of objects to be treated with a coating component using the roll coating device of the first embodiment, wherein:

[0152] While making a plurality of objects to be processed flow inside the storage unit, the coating treatment liquid is simultaneously sprayed by the spraying unit, and the coating component is cured by heating by the heating unit.

[0153] That is, in a figure 1 In the roll coating method of the predetermined roll coating device 20 shown, it is possible to simultaneously spray the coating treatment liquid by the spray unit 31 and pass through the heating unit while making a plurality of processed objects 10 flow on the bottom 29b of the housing unit 29. Since the coating component is cured by heating, the coating treatment liquid can be uniformly attached to a plurality of objects 10 to be processed, and can be cured uniformly while preventing the objects 10 from adheri...

Embodiment 1

[0201] As shown below, the effect of the height of the projection of the storage unit on the coating was confirmed by producing a covered molded article using the storage unit having the protrusions shown in Table 1, and measuring the thickness of the polyimide layer.

[0202] 1. Manufacture of coated moldings

[0203] (1) Prepare the object to be processed

[0204] First, the object to be processed is formed from a soft magnetic material into Figure 4 Shapes shown, each with an overall surface area of ​​10mm 2 , The coercive force is 40A / m.

[0205] In addition, when the temperature rises to about 500K, the coercive force of the object to be processed tends to decrease.

[0206] (2) Sandblasting

[0207] In addition, if Figure 5 As shown in FIG. 2 , blasting was performed using a blasting device with side peripheral walls having an octagonal rotating housing.

[0208] In this treatment, the rotating chamber was rotated at 11 rpm, and the alumina particles with an aver...

Abstract

The invention provides a roller coating device and a roller coating method capable of preventing processed objects from mutually adhering and thinly and evenly coating coated components. The roller coating device is provided with a rotary unit which is provided with a containing space and rotates surrounding a rotary shaft inclining in a specified angle relative to a level direction; a containingunit which is formed by meshed material and is provided with a cylinder part and a bottom part, and is mounted in the containing space by means that the center of the bottom is coherent with the rotary shaft, and rotates with the rotary unit under the condition of containing a plurality of processed objects; a spraying unit for spraying treatment fluid to the plurality of processed objects flowing in the containing unit; and a heating unit for curing the coated components adhered on the surface of the plurality of processed objects by heating the plurality of processed objects flowing in the containing unit, wherein the bottom part of the containing unit is provided with a protrusion part which protrudes to the upper side of the rotary shaft and causes the plurality of processed objects to flow between the protrusion part and the cylinder.

Description

technical field [0001] The present invention relates to a roll coating device and a roll coating method, and more particularly to a method for forming a coating film of a coating component with a uniform thickness on the surface of each object to be treated by adhering and curing a coating treatment liquid while flowing a plurality of objects to be treated A roll coating device and a roll coating method. Background technique [0002] Conventionally, in order to ensure electrical insulation, an insulating coating is formed on the surface of a magnetic core used in various electronic components. [0003] Therefore, a coated ferrite molded article in which the surface of the ferrite molded article is coated with a film containing a polyimide resin and a method for producing the same have been proposed (for example, refer to Patent Document 1). [0004] In addition, as a method of forming a thin film on a processed object such as a molded product, such as Image 6 As shown in (...
