Form for implementing the invention

(overall)

Fig. 1 is a schematic view of a coating device 10 according to an embodiment of the present invention. As shown in Fig. 1, the coating device 10 has a storage tank 1 for storing a coating liquid, a slit nozzle 3 for applying a coating liquid onto a curved substrate 11 on a holding tray 2, and a coating liquid from a storage tank 1 to a slit nozzle 3. The supply unit 4 is supplied and controls the control unit of the coating device 10. The slit nozzle 3 is a slit nozzle for a stage coater that forms a slit having a predetermined width for discharging the coating liquid on the nozzle itself, and applies the coating liquid to the base by moving the slit nozzle 3 material.

The storage tank 1 is supplied with high-pressure air, and the coating liquid is extruded from below by the pressure of the high-pressure air. With a mention, you can also not use The high-pressure air is used to extrude the coating liquid in the storage tank 1 by gravity.

The storage tank 1 is connected to the supply unit 4 through the two-way valve 12. The supply unit 4 has a syringe pump 44 driven by a motor 43 and a three-way valve 48. The storage tank 1 is connected to the first supply line 45 through the two-way valve 12, and the first supply line 45 is connected to the syringe pump 44 through the three-way valve 48. The syringe pump 44 is connected to the second supply line 49 through the three-way valve 48. The second supply line 49 is connected to the slit nozzle 3. The slit nozzle 3 is movable in the horizontal direction with respect to the holding tray 2, and a coating film is formed on the curved base material 11 on the holding tray 2 by the coating liquid applied from the slit nozzle 3. Incidentally, the control unit controls the supply from the storage tank 1 to the slit nozzle by controlling the supply unit 4 (specifically, controlling the operation of the syringe pump 44 driven by the motor 43 and the operation of the three-way valve 48). The supply pressure and/or supply amount of the coating liquid of 3.

2 is a schematic perspective view of the vicinity of a portion of the slit nozzle 3. As shown in FIG. 2, in the slit nozzle 3, the slit which is the discharge port of the coating liquid is formed only in a predetermined width in the nozzle moving direction (X direction) of the slit nozzle 3, and is formed in a slit orthogonal to the X direction. The direction Y is extended to form. Then, the coating liquid can be applied to the curved base material 11 on the holding tray 2 by a predetermined width by moving the slit nozzle 3 in the X direction. The control unit can adjust the moving speed of the slit nozzle 3 in the X direction. Specifically, the control unit controls the moving speed of the slit nozzle 3 in the X direction to be inversely proportional to the distance D from the slit tip end portion 3 a of the slit nozzle 3 to the coated surface 11 a of the curved base material 11 . Slot nozzle 3.

The curved base material 11 is curved from the Y direction so as to protrude downward, and the coated surface 11a on the upper surface has a concave curved surface, and the concave curved surface has a constant curvature. Moreover, the curved substrate 11 has a concave shape The surface is formed to extend in the Y direction.

Further, the coating liquid applied to the curved substrate 11 preferably has thixotropic properties. Thixotropy is the property of an intermediate substance that exhibits a gel-like plastic solid and a sol-like non-Newtonian liquid, meaning the property that viscosity will change over time. Specifically, if the shear stress is continuously applied, the viscosity gradually decreases and becomes liquid, and if it is stationary, the viscosity gradually rises and finally becomes solid. In the present embodiment, the coating liquid is thixotropy, whereby the coating liquid is liquidified by applying shear stress when being discharged from the slit nozzle 3, and the viscosity is gradually increased after being applied to the curved base material 11, and finally becomes solid. shape. In summary, the thixotropic coating liquid is a liquid which is generally high in viscosity but which has a reduced viscosity and a good fluidity when it is applied to pressure (common examples are paints, ketchup, mayonnaise), and is suitable for use in coatings as in the present invention. In the case where the coating film is discharged from a place where the coating film is thick to a place where the coating film is thin, after the pressure is applied and the fluidity is excellent, the viscosity is increased and the gas is not easily discharged when it adheres to the coated surface.

(hold the tray)

FIG. 3 is a schematic front view of the holding tray 2. As shown in FIG. 2 and FIG. 3, the holding tray 2 for holding the curved base material 11 has a pair of holding members 21, 22 and a supporting member at one end portion of the slit nozzle 3 in the slit direction (Y direction). 23 and 24, the former is held by sandwiching the curved base material 11 at both end portions of the curved base material 11 in the nozzle moving direction (X direction) of the slit nozzle 3, and the latter is disposed in a pair in the X direction. The curved base material 11 is supported from below between the sandwiching members 21 and 22. Further, the holding tray 2 has a pair of holding members 25, 26 and supporting members 27, 28 at the other end portion of the slit nozzle 3 in the slit direction (Y direction), the former being the nozzle movement at the slit nozzle 3. Direction (X direction) Both end portions of the surface substrate 11 are held by sandwiching the curved base material 11 therebetween, and the latter is disposed between the pair of holding members 25 and 26 in the X direction to support the curved base material 11 from below. Further, the holding member 21 and the supporting member 23, and the holding member 25 and the supporting member 27 are formed in a pair at both end portions of the curved base material 11 in the slit direction (Y direction) of the slit nozzle 3, and are sandwiched. The holding member 22 and the supporting member 24, and the holding member 26 and the supporting member 28 are provided in a pair at both end portions of the curved base material 11 in the slit direction (Y direction) of the slit nozzle 3.

The holding member 21 has a vertical portion 21a extending in the up-and-down direction and a horizontal portion 21b extending in the horizontal direction from the upper end portion of the vertical portion 21a. Here, in FIG. 3, the length A of the vertical portion 21a, the length B of the vertical direction of the slit nozzle 3 and the vertical portion 21a, the slit nozzle 3 (initial position), and the length C of the vertical portion 21a in the X direction are constant. Therefore, when the curved base material 11 is held by the sandwiching member 21, even if the thickness or curvature of the curved base material 11 changes, the length A, the length B, and the length C are constant, and therefore, even if the curvature of the curved base material 11 changes It is also possible to make the initial conditions of the operation of the coating device 10 constant. Incidentally, the holding members 21, 22, 25, 26 are formed in such a manner that the height of the lower end of the horizontal portion (that is, the length A of the vertical portion) is the same, and the both ends of the curved substrate 11 are at the same height. Come to clamp.

FIG. 4 is an enlarged perspective view of the clamp member 21. The holding members 22, 25, 26 have the same configuration as the holding member 21, and hereinafter, the holding member 21 is exemplified. As shown in FIG. 4, the horizontal portion 21b of the sandwiching member 21 is formed such that the horizontal end section of the lower end portion 21b2 is smaller than the upper end portion 21b1.

In order to match the direction of movement of the nozzle (X direction) of the curved substrate 11 The distance between the grip members 21, 22 is adjusted in length, and the grip member 22 is movable in the X direction with respect to the grip member 21. Specifically, the ball screw 201 that is engaged with the holding member 22 is provided to extend inward in the X direction from the X-direction end portion of the table 20, and can be rotated by rotating the handle 202 of the front end portion of the ball screw 201. The grip member 22 to which the ball screw 201 is engaged moves in the X direction. Further, since the holding member 22 and the supporting member 24 are mounted on the moving table 203 (which is mounted on the upper portion of the table 20 and is movable in the X direction), the holding member 22 is moved in the X direction by the ball screw 201. At this time, the mobile station 203 also moves in the X direction, and the support member 24 also moves in the X direction. As a result, the grip member 22 and the support member 24 are integrally moved in the X direction.

Similarly to the grip member 22, in order to adjust the distance between the grip members 25, 26 in accordance with the length of the curved substrate 11 in the nozzle moving direction (X direction), the grip member 26 can be along the X with respect to the grip member 25. Move in direction. Further, the support member 28 is moved integrally with the clamp member 26 in the X direction.

The support members 23, 24, 27, 28 have the same configuration. Hereinafter, the support member 23 will be exemplified. The support member 23 has a support portion 23a that comes into contact with the curved base material 11 at the upper end portion, and the support portion 23a can be moved up and down in the vertical direction by compressed air, electromagnetic force, or mechanical structure. The top of the support portion 23a has a spherical shape and is made of a resin. Further, the support member 23 has the potential energy member 23b to which the potential energy is applied in the vertical direction. The potential energy member 23b is, for example, a spring, and has a buffering function in the case of supporting the curved substrate 11. The potential energy member 23b is housed in the tubular member 23c, and the support portion 23a is raised and lowered.

(Installing the curved substrate for the holding tray)

5 to 7 are views for explaining the operation of attaching the curved base material 11 to the holding tray 2. First, as shown in FIG. 5, the moving table 203 is moved relative to the table 20, whereby the holding member 22 and the supporting member 24 are moved to the farthest distance from the holding member 21 and the supporting member 23 in the X direction. position.

Next, as shown in FIG. 6, one end portion of the curved base material 11 is sandwiched by the sandwiching member 21, and is supported by the support portion 23a of the support member 23 in the vertical direction while being supported from below by the support member 23. Curved substrate 11.

Finally, as shown in FIG. 7, the moving table 203 is moved with respect to the table 20, whereby the holding member 22 and the support member 24 are brought close to the holding member 21 and the support member 23. Then, the other end portion of the curved base material 11 is sandwiched by the sandwiching member 22, and the curved base material 11 is supported from below by the support member 24 while being supported by the support portion 23a of the support member 24 in the vertical direction. Incidentally, in the above mounting, the operation of the clamping member 25 and the supporting member 27 corresponds to the operation of the clamping member 21 and the supporting member 23, and the operation of the clamping member 26 and the supporting member 28 corresponds to the clamping member 22 and The operation of the support member 24 is supported.

The coating device 10 operates as follows.

First, high-pressure air is supplied to the storage tank 1 to be pressurized, and the two-way valve 12 is opened. Then, when the three-way valve 48 is used as the suction side and the motor 43 is rotated toward the suction side, the coating liquid in the storage tank 1 is filled in the syringe pump 44 through the first supply line 45 and the three-way valve 48.

After the filling of the syringe pump 44 is completed, the three-way valve 48 is switched to the discharge side. Then, the motor 43 is rotated toward the discharge side, and the syringe pump 44 is used. The coating liquid is supplied from the three-way valve 48 to the slit nozzle 3 through the second supply line 49. The control unit controls the motor 43 so that the supply pressure or the supply amount of the coating liquid is constant when the coating liquid in the syringe pump 44 is supplied to the slit nozzle 3. Then, the coating liquid is discharged from the discharge port 3b of the slit nozzle 3 to the curved base material 11 on the holding tray 2 so that the supply pressure or the supply amount is constant, and becomes a coating film.

According to the coating apparatus 10 of the above configuration, the following effects can be exhibited.

(1) The holding tray 2 is held by sandwiching the both ends of the curved base material 11 in the X direction by the holding members 21, 22, 25, and 26, and is disposed between the holding members 21, 22, and 25, 26 Since the support members 23, 24, 27, and 28 support the curved base material 11 from below, even if the base material is a curved surface, the curved base material 11 having a different R shape can be held.

(2) Since the holding members 21, 25 and the supporting members 23, 27, and the holding members 22, 26 and the supporting members 24, 28 are formed in a pair at both end portions of the curved base material 11 in the Y direction, The holding tray can be constructed with a minimum of the clamping member and the supporting member.

(3) Since the support portions of the support members 23, 24, 27, and 28 can be raised and lowered in the up and down direction, the support portion of the support members 23, 24, 27, and 28 can be adjusted in the up and down direction in accordance with the R shape of the curved base material 11. .

(4) Since the holding members 22, 26 are movable in the X direction, when the curved substrate 11 is to be held, the clamping members 22, 26 can be opened to a state larger than the width of the curved substrate 11. Since both end portions of the curved surface substrate 11 are sandwiched, it is easy to hold the curved base material 11. In addition, it can be combined with the curved substrate 11 in the X direction. The distance between the holding members 21, 22 and 25, 26 is adjusted by the length.

(5) Since the horizontal portion of the holding members 21, 22, 25, 26 is formed such that the horizontal section of the lower end portion is smaller than the upper end portion, the curved base material 11 and the holding members 21, 22, 25 can be reduced. , 26 contact area. As a result, the possibility of damage to the curved substrate 11 due to the contact of the holding members 21, 22, 25, 26 can be reduced.

(6) Since the sandwiching members 21, 22, 25, and 26 sandwich the both end portions of the curved base material 11 at the same height, the coating from the slit front end portion 3a to the curved base material 11 is specified at the nip position. The distance D from the surface 11a. As a result, even if the R shape of the curved base material 11 is changed, the initial positions of the slit nozzles 3 can be made the same, and the operation control of the slit nozzles 3 can be facilitated.

(7) Since the support members 23, 24, 27, and 28 have the potential energy-applying members that impart potential energy in the up-and-down direction, the cushion base material can prevent the curved base material 11 from being excessively stressed when being carried on the support member. The damage of the curved substrate 11 and the support of the support members 23, 24, 27, 28 can be improved by the error of the shape of the curved substrate 11.

(8) Since the support member 24 is integrally moved with the grip member 22 in the X direction, the support member 28 is integrally moved with the grip member 26 in the X direction, so that the grip member 22 can be maintained When the positional relationship of the support member 24 is maintained, the movement is in the X direction, and the X direction can be moved while maintaining the positional relationship with the clamp member 26 and the support member 28. Therefore, the positional adjustment of the holding member 22 and the supporting member 24, the holding member 26, and the supporting member 28 for holding the curved base material 11 can be easily performed.

(9) Since the upper ends of the support members 23, 24, 27, 28 are Since it has a spherical shape, the contact area of the curved base material 11 and the supporting members 23, 24, 27, 28 can be reduced. As a result, the possibility of damage to the curved substrate 11 due to the contact of the supporting members 23, 24, 27, 28 can be reduced. Further, since the upper end portions of the supporting members 23, 24, 27, 28 are made of resin, the possibility of damage to the curved base material 11 due to the contact of the supporting members 23, 24, 27, 28 can be reduced.

(10) Since the sandwiching members 21 and 25 on the initial position side of the slit nozzle 3 are fixed, and the sandwiching members 22 and 26 are moved in the X direction to sandwich the curved base material 11, the initial position of the slit nozzle 3 is obtained. And the clamping position of the curved substrate 11 caused by the holding members 21, 25 is fixed. As a result, the initial conditions of the operation of the coating device 10 can be made constant, and the operation control of the slit nozzle 3 can be facilitated.

(11) The moving speed of the slit nozzle 3 in the state where the supply pressure to the coating liquid of the slit nozzle 3 is constant is the distance from the slit front end portion 3a to the coated surface 11a of the curved base material 11 D moves the slit nozzle 3 in an inversely proportional manner, whereby the coating liquid is applied to the curved base material 11 so that the upper surface of the coating liquid becomes a flat surface.

(12) In a state where the supply amount of the coating liquid to the slit nozzle 3 is constant, the moving speed of the slit nozzle 3 is the distance from the slit front end portion 3a to the coated surface 11a of the curved base material 11. D moves the slit nozzle 3 in an inversely proportional manner, whereby the coating liquid is applied to the curved base material 11 so that the upper surface of the coating liquid becomes a flat surface.

(13) The adhesive can be applied to the concave curved surface of the curved base material 11 as a coating liquid, whereby the adhesive is applied to the concave curved surface so that the upper surface of the adhesive becomes a flat surface. As a result, convex curved glass and flat glass The bonding is easy, and the sheet-side convex glass can be easily formed.

(14) When the coating liquid has thixotropic properties, the movement of the coating liquid applied to the curved base material 11 can be suppressed, and the coating liquid can be applied flatly in a predetermined field of the curved base material 11. Further, when the coating liquid has thixotropic properties, the coating liquid after the discharge has a high viscosity. Therefore, even if the coating thickness changes during coating as in the case where the curved base material 11 is applied in a plane, coating is less likely to occur. When the liquid flows from a thick portion to a thin portion and the thickness is changed, the upper surface of the coating liquid can be made into a suitable plane.

In the above embodiment, the support member is provided in two in the nozzle moving direction (X direction), but one or three or more may be provided.

In the above embodiment, the holding member and the supporting member are provided in a pair at both end portions of the curved base material 11 in the slit direction (Y direction) of the slit nozzle 3, but the holding member and the supporting member may be It is set to have three or more predetermined intervals in the Y direction.

According to this configuration, since the sandwiching member and the supporting member are provided in plural in the slit direction at predetermined intervals, the holding tray can be constituted by a reasonable number of holding members and supporting members.

In the above embodiment, the sandwiching members 22 and 26 are movable in the X direction with respect to the sandwiching members 21 and 25. However, it is also possible that the gripping members 21, 25 are movable in the X direction with respect to the gripping members 22, 26. Further, the holding members 21 and 22 may be integrally moved in the X direction so as to maintain the position of the intermediate line between the holding members 21 and 22, so that the holding members 25 and 26 are to maintain the holding members. The position of the middle line between the 25 and 26 is integrally moved along the X direction. To achieve such a clamping member 21, 22, it can be The moving stages 203 and 204 move relative to the stage 20 so as to maintain the position of the intermediate line between the sandwiching members 21 and 22. Thereby, even if the size of the curved base material 11 is different, the curved base material 11 can always be held by holding the center of the tray 2.

8 to 10 are views for explaining that the holding members 21 and 22 are integrally moved in the X direction so as to maintain the position of the intermediate line L between the sandwiching members 21 and 22, so that the holding members 25 and 26 are held by the holding members. In the case where the position of the intermediate line L between the members 25 and 26 is integrally moved in the X direction, the operation of attaching the curved base material 11 to the holding tray 2 different from the above embodiment is shown. Regarding the movement integrally in the X direction in such a manner as to maintain the position of the intermediate line L between the sandwiching members 21, 22, for example, when the holding member 21 is moved away from the holding member 22, the clamping is performed. The member 22 is also moved by the same distance away from the holding member 21, and when the holding member 21 is moved toward the holding member 22, the holding member 22 is also moved by the same distance toward the holding member 21. The meaning of moving integrally along the X direction so as to maintain the position of the intermediate line L between the sandwiching members 25 and 26 is also the same as described above. Incidentally, the tubular members 23c and 24c have bottom portions 23d and 24d, and the bottom portions 23d and 24d are movable in the vertical direction with respect to the hole portions 23e and 24e.

At the same time, the other end portion of the curved base material 11 is held by the sandwiching member 22, and the tubular member 24c is lifted upward from the hole portion 24e by compressed air or the like from below the bottom portion 24d, so that the support member 24 is lifted. The support portion is raised and lowered upward, and the curved base material 11 is supported from below by the support member 24. Incidentally, in the above mounting, the operation of the clamping member 25 and the supporting member 27 corresponds to the operation of the clamping member 21 and the supporting member 23, and the operation of the clamping member 26 and the supporting member 28 corresponds to the clamping member 22 and The operation of the support member 24 is supported. By the series of actions, the curved substrate 11 is transferred from the upper surface of the robot 209 to the table 20 below. At this time, the robot 209 may be moved downward to leave the lower surface of the curved base material 11.

According to this configuration, since the sandwiching members 21, 22, 25, and 26 are integrally moved to maintain the position of the intermediate line, even if the size of the curved base material 11 is different, the curved base material 11 can be held in the holding tray 2. The center portion is held, and the distance between the sandwich members 21, 22, 25, and 26 can be easily adjusted in accordance with the length of the curved base material 11 in the X direction. Further, since the support member 23 integrally moves with the clamp member 21 in the X direction, and the support member 24 integrally moves with the clamp member 22 in the X direction, the clamp member 21 can be maintained. In the case of supporting the positional relationship of the member 23, moving in the X direction, another Further, the X direction can be moved while maintaining the positional relationship with the sandwiching member 22 and the supporting member 24. Further, since the support member 27 is integrally moved with the clamp member 25 in the X direction, and the support member 28 is integrally moved with the clamp member 26 in the X direction, the support member 25 can be maintained and held. When the positional relationship of the support member 27 is maintained, the movement is in the X direction, and the X direction is maintained while maintaining the positional relationship with the sandwiching member 26 and the support member 28. Therefore, the holding member 21 and the supporting member 23 for holding the curved base material 11, the holding member 22 and the supporting member 24, the holding member 25 and the supporting member 27, the holding member 26, and the supporting member 28 can be easily performed. Position adjustment.

Further, in the above embodiment, the holding member 21 and the supporting member 23, and the holding member 25 and the supporting member 27 are provided at both end portions of the curved base material 11 in the slit direction (Y direction) of the slit nozzle 3. In a pair, the holding member 22 and the supporting member 24, and the holding member 26 and the supporting member 28 are formed in a pair at both end portions of the curved base material 11 in the slit direction (Y direction) of the slit nozzle 3. . However, as shown in FIG. 11, the holding member 210 and the supporting member 230, and the holding member 220 and the supporting member 240 may be provided so as to extend over the entire length of the curved base material 11 in the Y direction. These members may extend over the entire length of the curved base material 11 in one direction as shown in FIG. 11, or may be appropriately divided in the middle, and may have a plurality of predetermined intervals.

According to this configuration, since the sandwiching members 21 and 22 and the supporting members 23 and 24 extend in the Y direction and extend over the entire length of the curved base material 11, the retainability of the curved base material in the Y direction can be improved.

The spirit of the invention described in the patent application scope is not exceeded. Various modifications and changes are possible in the case of the range.
