Technical Field
The present invention relates to a coating apparatus for applying a coating material to a substrate.
Background
There are cases where a resist coating material or a conductive coating material, an insulating coating material, a protective coating material, a reinforcing coating material, a UV (Ultraviolet) light shielding coating material, an antistatic coating material, a coloring coating material, a functional coating agent, or the like (hereinafter, these are collectively referred to as "coating materials") is applied to the surface of a substrate, a film, a sheet, a plate, a panel, or the like (hereinafter, these are collectively referred to as "base materials").

Disclosure of Invention
[ problem to be solved by the invention ]
However, in the coating apparatus, since only the doctor roller is in direct contact with the coating material, the uniformity of the film thickness of the coating material applied to the substrate depends on the amount of coating material adhering to the doctor roller or the smoothness of the coating material on the surface of the doctor roller, the amount of coating material transferred from the doctor roller to the coating roller, and the smoothness of the transferred coating material.
Therefore, for example, in the case where the coating material on the doctor roll surface lacks smoothness, the coating material transferred to the coating roll surface becomes uneven, and as a result, the film thickness of the coating material transferred to the substrate becomes uneven.
In general, since smoothness of a coating film applied to a substrate affects mounting density of electronic parts, it is desirable that the coating film be as smooth as possible. In the coming 5G era, the demand for higher density substrates has not been increased yet at present.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coating apparatus capable of forming a coating film having excellent smoothness as compared with a conventional coating apparatus.
[ means for solving the problems ]
The coating device of the invention coats the coating on the substrate, and comprises a coating roller, a scraper roller and a supporting component. In the coating device of the present invention, the liquid storage portion is formed by the support member, the coating roller, and the doctor roller so that the coating material adheres to the coating roller and the doctor roller.
[ Effect of the invention ]
The coating device of the present invention has the liquid storage portion formed so that the coating material adheres to the coating roller and the doctor roller, and therefore the amount of the coating material adhering to the coating roller is stable, and a smooth coating film can be formed on the substrate.

Detailed Description
(embodiment 1)
An example of an embodiment of the coating device of the present invention will be described with reference to the drawings. As an example, the coating apparatus shown in fig. 1 is an apparatus for applying a coating material on a substrate P, and includes a coating roller 1, a doctor roller 2, and a support member 3. In this embodiment, the liquid reservoir 4 is formed by the support member 3, the coating roller 1, and the doctor roller 2 so that the coating material adheres to the coating roller 1 and the doctor roller 2. At both outer sides in the longitudinal direction of the applicator roll 1 and the doctor roll 2, there are provided anti-scattering tools 5 for preventing the paint accumulated in the liquid reservoir 4 from scattering. As shown in fig. 2, the coating roller 1, the doctor roller 2, and the supporting member 3 are provided at the same height on both sides across the substrate P.
The coating roller 1 is a member for transferring a coating material onto a substrate P to form a coating film. The coating roller 1 may be a rubber roller or a metal roller, and a roller having a DLC (Diamond-Like Carbon) film on the outer periphery thereof may be used. The rubber roller includes natural rubber and synthetic rubber. The metal roll includes a roll obtained by plating carbon steel, and the like.
In this embodiment, a solid roll having no irregularities (grooves) on the outer peripheral surface is used as the coating roll 1, but instead of the solid roll, an engraved roll having grooves of various shapes such as spiral grooves, single grooves, dots, and the like on the outer peripheral surface may be used as the coating roll 1. The shape of the groove is an example, and other shapes may be used.
The applicator roll 1 of this embodiment is configured to always rotate regardless of whether or not it is in contact with the substrate P. The coating rolls 1 are rotated in the reverse direction with respect to the moving direction of the substrate P, specifically, one (left side in the drawing) of the coating rolls 1 is rotated in the clockwise direction and the other (right side in the drawing) of the coating rolls 1 is rotated in the counterclockwise direction as shown in fig. 2. The applicator roll 1 may also be rotated in the opposite direction (forward direction relative to the direction of movement of the substrate P). In any case, the doctor roller 2 is configured to rotate in a direction opposite to the rotation direction of the doctor roller.
The doctor roll 2 is a member for supplying paint to the applicator roll 1 and smoothing (leveling) the paint on the surface of the applicator roll 1. The doctor roll 2 may be a roll having a DLC film on the outer periphery thereof, other than a metal roll or a rubber roll. The rubber roller includes natural rubber and synthetic rubber. The metal roll includes a roll obtained by plating carbon steel, and the like.
In this embodiment, a metal roller having a DLC film on the outer periphery of carbon steel is used as the doctor roller 2. Although not shown, the outer peripheral surface of the doctor roller 2 is provided with various shapes of irregularities (grooves) such as spiral grooves, single grooves, dots, and the like. The shape of the groove is an example, and other shapes may be used. The doctor roll 2 may also be a solid roll without grooves.
In this embodiment, rolls having the same diameter and length are used as the coating roll 1 and the doctor roll 2. The coating roll 1 and the doctor roll 2 may be rolls having different diameters or lengths. However, it is preferable to use a roll having a larger diameter than the coating roll 1 for the doctor roll 2. By using the doctor roller 2 having a larger diameter than the coating roller 1, the coating material on the outer peripheral surface of the coating roller 1 becomes easily homogenized because the portion of the doctor roller 2 on which the coating material is attached is always in contact with the coating roller 1 during one turn of the coating roller 1.
The support member 3 is a member that forms a liquid reservoir 4 between the applicator roll 1 and the doctor roll 2. The support member 3 of this embodiment is a flat plate member slightly longer than the applicator roll 1 and the doctor roll 2. The support member 3 may be formed of resin, rubber, or the like, other than metal.
As shown in fig. 2, the support member 3 of this embodiment is provided to have a size that spans both the applicator roll 1 and the doctor roll 2. The support member 3 is inclined with respect to an imaginary axis (indicated by a two-dot chain line in fig. 2) parallel to a straight line in the moving direction of the vertically moving substrate P so that an angle α formed between the imaginary axis and the lower end side of the support member 3 is about 40 degrees. The angle can be adjusted appropriately.
In this embodiment, the applicator roll 1 is in contact with the doctor roll 2, the applicator roll 1 is in contact with the support member 3, and a reservoir 4 for accumulating paint is formed by using the contact. Specifically, a liquid reservoir 4 is formed between the support member 3 and the coating roller 1 and the doctor roller 2, and the coating material stored in the liquid reservoir 4 adheres to both the coating roller 1 and the doctor roller 2.
As in this embodiment, when the paint accumulated in the liquid reservoir 4 is directly adhered to the coating roller 1, the coating roller 1 itself can scrape off the paint, so that uneven coating of the paint applied to the substrate P is less likely to occur even if the amount of paint transferred from the doctor roller 2 is small, and a smooth coating film can be formed on the surface of the substrate P.
In this embodiment, the doctor roll 2 is disposed further outside and higher than the applicator roll 1. When such a positional relationship is set, there are the following advantages: the paint adhering to the coating roller 1 can be transferred to the substrate P without falling down by gravity. In addition, since the distance from the contact point with the doctor roller 2 to the substrate P becomes short, there are the following advantages: even in the case of applying a coating material which is easily volatilized, it is possible to transfer the coating material to the substrate P before volatilization.
The coating device of this embodiment includes a holder 6, a lower support 7, a pressing pin 8, and a posture holder 9 in addition to the coating roller 1, the doctor roller 2, and the support member 3. The holder 6, the lower support 7, the pressing pin 8, and the posture holder 9 may be provided as needed, and may be omitted or replaced by other means.
The holder 6 holds the substrate P so as to move in the up-down direction. The holder 6 of this embodiment is a clamp-like member for holding the upper portion of the substrate P. The holder 6 is configured to be lifted by a lifting device, not shown. As shown in fig. 1 and 3 (a), in this embodiment, the case where there are three holders 6 is taken as an example, but there may be more than three holders 6 or fewer than three holders 6.
In the case of holding a soft substrate such as a soft substrate, a holder 6 for holding both ends of the substrate P in the width direction as shown in fig. 3 (b) may be used to suppress the wobbling of the substrate P. The holder 6 has a length capable of holding the entire length or substantially the entire length of the substrate P in the longitudinal direction. Other holders than those may be used for the holder 6.
The lower support 7 supports the substrate P lowered to a specific position from the lower side. In this embodiment, a コ -shaped upward gutter-like member longer than the width direction of the base material P is used as the lower support 7. The lower support 7 is disposed at a position lower than the applicator roll 1 or the posture holder 9 and the pressing pin 8. The lower support 7 is provided at a position where the vicinity of the upper end of the substrate P becomes the same level as the coating roller 1 when the substrate P reaches the lower support 7.
The pressing pins 8 are pin-like members that temporarily press both surfaces of the substrate P lowered to a specific position. The pressing pin 8 of this embodiment is configured to move in a direction approaching the substrate P and a direction separating from the substrate P by a driving means not shown. In this embodiment, the case where two (four in total) are provided on the outer side of each surface of the base material P is taken as an example, but the number of the pressing pins 8 may be more than four or less than four.
The posture holder 9 is a member for holding the standing posture of the substrate P by contacting or approaching both surfaces of the substrate P. The posture holder 9 of this embodiment is a rectangular parallelepiped block made of rubber. In this embodiment, the posture holder 9 is provided in two (four in total) on the outer side of one surface of the base material P and in two on the outer side of the other surface. As shown in fig. 3 (a) and 3 (b), the posture holders 9 on the outer side of each surface are provided at intervals in the width direction of the base material P. The number of the posture holders 9 may be more than four or may be less than four.
Each of the posture holders 9 of the present embodiment is configured to be moved in a direction approaching the substrate P and a direction separating from the substrate P by a driving means not shown. Each of the posture holders 9 may be individually movable, but in this embodiment, both the posture holders 9 pressing the same surface of the substrate P are moved in synchronization.
In this embodiment, the posture holder 9 is moved separately from the coating roller 1, the doctor roller 2, and the supporting member 3, but the posture holder 9 may be moved in synchronization with the coating roller 1, the doctor roller 2, and the supporting member 3. The posture holders 9 may be fixed at fixed positions without being moved.
Each of the posture holders 9 is provided below the applicator roll 1. The posture holder 9 may be provided in contact with the applicator roll 1 or may be provided away from the applicator roll 1. When the posture keeping member 9 is provided so as to contact the applicator roll 1, the upper surface of the posture keeping member 9 may be recessed in an arc shape so as to extend along the outer periphery of the applicator roll 1.
In this embodiment, the posture holder 9 is set to be made of rubber, but the posture holder 9 may not be made of rubber. In any case, when the coating material is applied by the applicator roll 1, the frictional resistance is preferably low to such an extent that smooth movement (lifting) of the substrate P is not impaired. The posture holder 9 may be formed in a shape having a small contact area so as not to interfere with the smooth rising of the substrate P. In addition, at least the contact surface of the posture holder 9 can be subjected to a fluororesin process to reduce friction resistance.
In this embodiment, the case where the paint is applied while the substrate P is lifted up is taken as an example, but the paint may be applied while the substrate P is lowered as shown by a one-dot chain line in fig. 2. In this case, the coating roller 1 may rotate in the reverse direction with respect to the moving direction of the substrate P, or may rotate in the forward direction with respect to the moving direction of the substrate P.
(embodiment 2)
Another example of the embodiment of the coating device of the present invention will be described with reference to the drawings. The basic configuration of the coating device of this embodiment is the same as that of embodiment 1. The difference is in the way the substrate P is moved. In the above embodiment, the case where the substrate P is held by the holder 6 and moved in the up-down direction (the case where the substrate P is a single sheet) is taken as an example, but the coating apparatus of the present invention may be an apparatus for coating a coating material on the substrate P that is moved by the roll-to-roll method as shown in fig. 4.
Specifically, as shown in fig. 4, the take-up roll 10 and the take-up roll 11 may be arranged with a gap therebetween in the up-down direction, and the substrate P may be taken up from the take-up roll 10 and taken up by the take-up roll 11.
In the example shown in fig. 4, the case where the unwinding roller 10 is provided on the lower side and the winding roller 11 is provided on the upper side is shown as an example, but the following configuration may be adopted: the take-up roll 10 and the take-up roll 11 are vertically exchanged, and the coating material is applied while the substrate P is moved downward as shown by a one-dot chain line in fig. 4.
In the case of the configuration shown in fig. 4, the same components as those of embodiment 1 can be used for the applicator roll 1, the doctor roll 2, and the support member 3. In addition, in the case of moving the substrate P by the roll-to-roll system, the holder 6, the lower support 7, the pressing pin 8, and the posture holder 9 may be omitted.
(other embodiments)
In the above two embodiments, the case where the diameters of the coating roller 1 and the doctor roller 2 are the same is taken as an example, but the coating roller 1 and the doctor roller 2 having different diameters may be used. In the above embodiment, the case where the lengths of the coating roller 1 and the doctor roller 2 are the same is taken as an example, but the coating roller 1 and the doctor roller 2 having different lengths may be used.
In the above two embodiments, the case of using a solid roll as the coating roll 1 and using an engraved roll as the doctor roll 2 is taken as an example, but it is also possible to use an engraved roll as the coating roll 1 and a solid roll as the doctor roll 2. In addition, if possible, both the coating roller 1 and the doctor roller 2 may be solid rollers or engraved rollers.
In the above two embodiments, a case where a rubber roller is used as the coating roller 1 and a metal roller (a roller obtained by forming a DLC film on carbon steel) is used as the doctor roller 2 is taken as an example, but the metal roller may be used as the coating roller 1 and a rubber roller may be used as the doctor roller 2. In addition, if possible, both the coating roller 1 and the doctor roller 2 may be metal rollers or rubber rollers.
For example, a roll obtained by applying an HC coating film or a Ni coating film to the surface of all of stainless steel typified by austenitic or martensitic iron such as SUS304 or SUS440C, carbon steel such as STKM13A or S25C, or applying a DLC coating film to the surface of stainless steel, carbon steel, or HCr coating film can be used as the metal roll.
In the above two embodiments, the doctor roller 2 is disposed at a position higher than the application roller 1 as an example, but as shown in fig. 5, the doctor roller 2 may be disposed at a position lower than the application roller 1 (lower position). In this case, in the figure, the doctor roll 2 located on the left side of the substrate P rotates in the clockwise direction, and the applicator roll 1 on the same side rotates in the counterclockwise direction. On the other hand, in the figure, the doctor roll 2 located on the right side of the substrate P rotates in the counterclockwise direction, and the coating roll 1 on the same side rotates in the clockwise direction. This structure is easily adopted when the viscosity of the paint is high enough not to drop by gravity.
In the above two embodiments, the explanation is omitted, but the doctor roller 2 may be moved in the direction in which the applicator roller 1 is pushed in and the direction opposite to the direction (the direction in which the pushing in is released). Similarly, the applicator roll 1 is movable in a direction in which the substrate P is pushed in and in a direction opposite to the direction (direction in which pushing is released).
In the above-described embodiments, the case where the coating roller 1, the doctor roller 2, and the supporting member 3 are provided at the same height on both sides across the substrate P is taken as an example, but as shown in fig. 6, the coating roller 1, the doctor roller 2, and the supporting member 3 may be provided at different heights on both sides across the substrate P. This structure is a structure that is easily adopted when the base material P is a soft material such as a film or a copper foil.
In the above-described embodiments, the case where the anti-sprinkling tool 5 is provided on both outer sides in the longitudinal direction of the applicator roll 1 and the doctor roll 2 is taken as an example, but the anti-sprinkling tool 5 may be omitted by adding a structure corresponding to the anti-sprinkling tool 5 to the support member 3.
In the above two embodiments, a case where a roll having one roll member provided on the outer periphery of the core material is used as the coating roll 1 is taken as an example, but the coating roll 1 may be a roll having a coating portion 13 and an abutment portion 14 having a larger diameter than the coating portion 13 provided on the outer periphery of the core material 12 as shown in fig. 7 (a) and 7 (b). The coating portion 13 and the two contact portions 14 of the roller are independent units, and the two contact portions 14 are provided with a gap (gap S) between the two outer sides in the longitudinal direction of the coating portion 13.
The core 12 is a member for supporting the coating portion 13 and the contact portion 14. The core material 12 may be an existing core material such as an iron core. The core 12 may be solid wood or hollow (pipe).
The coating portion 13 is a roller-shaped pipe member provided on the outer periphery of the core material 12. In this embodiment, a rubber roller is used as the coating portion 13. The rubber roller includes natural rubber and synthetic rubber. Although not shown, the outer peripheral surface of the coating portion 13 is provided with projections and depressions (grooves) having various shapes such as a lattice shape, a pyramid shape, a spiral shape, and the like. The shape of the groove is an example, and other shapes may be used.
The abutting portion 14 is a roller-like member that is independent of the coating portion 13. In this embodiment, the same rubber roller as the coating section 13 is used. In this embodiment, the abutment portion 14 is provided one (two in total) on both outer sides in the longitudinal direction of the application portion 13. The contact portion 14 has a diameter larger than the coating portion 13 by about 0.2 to 0.6 mm. The size is an example, and may be other sizes.
In this embodiment, the contact portion 14 is disposed with a gap S between the application portion 13 and each of both sides in the longitudinal direction thereof. The gap S is a space for disposing the sprinkler 5 (see fig. 1). In this embodiment, the gap S is set to accommodate a width of 28mm of the sprinkler head 5, as an example. The gap S may also be set to accommodate the amplitude of two anti-spillage means 5 of width 28 mm. The width of the gap S shown here is an example, and the gap S may be wider or narrower than the width. The gap S may be a width of the sprinkler 5.
When the rolls shown in fig. 7 (a) and 7 (b) are used as the coating rolls 1, it is preferable to use two coating rolls 1 as the rolls shown in fig. 7 (a) and 7 (b), but any of the coating rolls 1 may be used as the rolls shown in fig. 7 (a) and 7 (b).
In the case of using the rolls shown in fig. 7 (a) and 7 (b) as the coating roll 1, the doctor roll 2 paired with the coating roll 1 may be a roll shown in fig. 7 (a) and 7 (b).
The roller (applicator roller 1) shown in fig. 7 (a) and 7 (b) is also provided with a gear connected to a drive motor at one end side, and is rotatably supported by a shaft at the other end side by a bearing, though not shown.
The present invention is not limited to the structure or shape of each of the above embodiments, and various modifications and changes can be made without departing from the gist thereof.
Next, an operation of the coating apparatus of the present invention will be described with reference to the drawings. Here, as an example of the operation of the coating device of the present invention, the operation of the coating device of embodiment 1 and the operation of the coating device of embodiment 2 will be described.
The coating apparatus according to embodiment 1 operates as follows. In fig. 8 (a) to 8 (d) and fig. 9 (a) to 9 (d), the holder 6, the pressing pin 8, and the posture holder 9 are shown in a solid line in a state of being in contact with or approaching the substrate P, and in a two-dot chain line in a state of being not in contact with or approaching the substrate P.
(1) The substrate P held by the holder 6 is set at a specific position (fig. 8 (a) and 9 (a)).
(2) The substrate P held by the holder 6 is lowered to a specific position and supported by the lower support 7 (fig. 8 (b) and 9 (b)).
(3) The pressing pins 8 are abutted against both surfaces of the substrate P to hold the substrate P (fig. 8 (c) and fig. 9 (c)). At this time, the holding tool 6 releases the holding of the substrate P immediately before the substrate P is held by the pressing pins 8. The posture holder 9 is brought into close proximity to or contact with both surfaces of the substrate P, and holds the standing posture of the substrate P.
(4) The coating rollers 1 on both sides of the substrate P are brought into contact with the substrate P, and the coating material held on the surfaces of the coating rollers 1 is transferred to the substrate P (fig. 8 (d) and 9 (d)). At this time, the upper end portion of the substrate P is again held by the holder 6, and the substrate P is pulled up, and the coating material on the surface of the coating roller 1 is transferred to the pulled-up substrate P. The holding of the base material P by the pressing pin 8 is released immediately before the application roller 1 comes into contact with the base material P.
The coating device according to embodiment 2 operates as follows.
(1) The base material P held by the take-up roll 10 and the take-up roll 11 is set at a specific position (fig. 10 a and 11 a).
(2) The coating roller 1 is abutted against both surfaces of the substrate P moving from the unwinding roller 10 side to the winding roller 11 side by the operations of the unwinding roller 10 and the winding roller 11, and the coating material held on the surface of the coating roller 1 is transferred to the substrate P (fig. 10 (b) and 11 (b)).
In both operations, the coating material applied to the substrate P by the applicator roll 1 is the coating material supplied by the doctor roll 2 and the coating material scraped off by the applicator roll 1 itself, and is flattened to a specific thickness when passing through both rolls.
As described above, in the coating device according to each of the above embodiments, since the coating material is supplied not only to the coating roller 1 by the doctor roller 2 but also to the coating roller 1 itself, the amount of the coating material adhering to the coating roller 1 is easily stabilized, and a smooth coating film can be formed on the substrate P.
The coating device of the present invention can be used for coating various kinds of base materials P with a coating material, and in particular, can be suitably used for coating a printed wiring board such as a rigid board or a flexible board with a resist, or for coating a copper foil with an adhesive agent.
