Description

  In order to form a thin film electrode such as a fuel cell, a lithium ion battery, or a dye-sensitized solar cell in a laboratory or a laboratory, the present invention is fixed to a screen frame for screen printing, and an inclination of a squeegee is set to a desired angle. The present invention relates to a squeegee holding device for printing by manually holding and linearly moving a squeegee.

  Conventionally, when screen printing is performed manually, a squeegee made of an elastic material such as urethane rubber, a ceramic squeegee, a metal squeegee, etc. is attached to the squeegee holder, and an image pattern is placed on a screen cage stretched on a rectangular screen frame. After supplying a viscous printing material such as ink, paste, or slurry to a pre-made screen plate or a metal mask plate (hereinafter collectively referred to as a screen plate) in which an image pattern is cut out by a technique such as etching, a printing worker Grips the squeegee holder, slides the viscous printing material in the printing direction while pressing the squeegee against the screen plate, and slides the viscous printing material to form a thin film of the viscous printing material on the substrate (hereinafter referred to as a workpiece).

  The Tokyo Metropolitan Industrial Technology Research Institute “Screen Printing Technology and its Applications” 1997 special training text by field (June 1997), the main factors affecting ink film thickness and printing line width are the printing speed and squeegee. Hardness, squeegee angle, ink viscosity, and squeegee pressing force are presented. Among these main factors, the printing speed, squeegee angle, and squeegee pressing force are the human factors that the printing operator has on the printing results. It has been.

  However, in the conventional printing method, the above-described artificial operation in which the inclination of the squeegee holder is held at a constant angle with respect to the printing direction, pressed against the screen plate with a constant force, and slid at a constant speed in the printing direction. Since considerable skill is required to satisfy the factors, it is difficult for an unskilled operator to control the film thickness and line width of the printed thin film to be constant.

In addition, in the semi-automatic screen printing device equipped with the automatic feeding mechanism of the viscous printing material and the automatic feeding mechanism of the squeegee, and the automatic screen printing device equipped with the automatic feeding mechanism of the workpiece, the above-mentioned human factors are made constant. Although it can be maintained, the apparatus is heavy and the cost is high. In addition, when printing only a small number of several types of viscous printing materials with components and contents changed as parameters, it takes time to clean the screen plate and automatic feeding mechanism, and the viscous printing material is wasted. Is not suitable.

A holder pressing means for pressing the plate may be provided. Further, the slide rail may be provided with a device fixing means for fixing to the screen frame or the screen printing apparatus, and the slide rail does not include the device fixing means and is directly incorporated in the screen frame or the screen printing apparatus. May be.

  Hereinafter, features of the squeegee holding device according to the present invention will be described in detail. The method of attaching a squeegee made of an elastic material such as urethane rubber, a ceramic squeegee, a metal squeegee, etc. to the squeegee holder is not particularly limited, and various methods conventionally employed can be adopted. . For example, a method may be employed in which an upper portion of a rectangular squeegee is fitted into a squeegee holder including two sandwiching plates provided with stepped portions, and the sandwiching plate is tightened with screws.

  The holder mounting means engages the protruding portion provided on either the squeegee holder or the holding device main body and the receiving portion provided on the other, and places the protruding portion in the receiving portion to hold the squeegee holder in the holding device. Attach to the body. The holder mounting means is roughly classified into two categories: a case in which the squeegee holder is provided with a protruding portion and a case in which a receiving portion is provided. Further, the squeegee holder is free when the squeegee holder is mounted on the holding device body. Depending on the degree, each major classification can be further divided into three minor classifications.

  FIG. 8 shows the concept of the holder mounting means when the protruding portion is provided on the squeegee holder and the receiving portion is provided on the holding device main body, and the shape of the protruding portion is a semicircular shape (a shape in which a rectangular parallel short side is a semicircle). Is illustrated. In the first sub-class, the projecting portion has no degree of freedom relative to the receiving portion on the XY plane, and is fixed. The protrusion is attached or detached by moving and returning the protrusion or the receiving portion in the Z direction. In the second sub-class, the projecting portion has a degree of freedom in one direction with respect to the receiving portion on the XY plane. The protrusions are attached and detached by moving the protrusions in that direction. However, in the second subcategory, those that restrict the degree of freedom in the attaching / detaching direction by a mechanism such as a presser provided on the projecting part or the receiving part after mounting the projecting part on the receiving part are the first subclasses. Belonging to. In the third subcategory, the projecting part has a degree of freedom in multiple directions with respect to the receiving part on the XY plane. The protrusion is attached or detached by placing the protrusion on the receiving portion. However, even in the third sub-classification, after the projecting portion was mounted on the receiving portion, the one that restrains the degree of freedom in the attaching / detaching direction by a mechanism such as a presser provided on the projecting portion or the receiving portion remained. It belongs to the first or second subclass depending on the degree of freedom.

  Next, FIG. 9 exemplifies the concept of the holder mounting means when the receiving portion is provided on the squeegee holder and the protruding portion is provided on the holding device main body, and the shape of the protruding portion is a semicircular shape. In the first subclass, the receiving portion does not have a degree of freedom with respect to the protruding portion, and is fixed on the XY plane. The attachment / detachment of the receiving portion is performed by moving and returning the protruding portion or the receiving portion in the Z direction. In the second subclass, the receiving portion has a degree of freedom in one direction with respect to the protruding portion on the XY plane. The attachment / detachment of the receiving portion is performed by moving the receiving portion in that direction. However, in the second subcategory, the first subcategory is one in which the degree of freedom in the attaching / detaching direction is restricted by a mechanism such as a presser provided on the projecting part or the receiving part after the receiving part is mounted on the projecting part. Belonging to. In the third sub-class, the receiving portion has a multi-directional degree of freedom with respect to the protruding portion on the XY plane. The receiving part is attached and detached by placing the receiving part on the protruding part. However, even in the third sub-class, after the receiving portion was mounted on the protruding portion, the one that restrains the degree of freedom in the attaching / detaching direction by a mechanism such as a presser provided on the protruding portion or the receiving portion remained. It belongs to the first or second subclass depending on the degree of freedom.

  In the first subcategory, the squeegee holder does not have a degree of freedom in the XY plane, and therefore has a structure that already has a holder restraining mechanism. However, in the second and third sub-classes, the squeegee holder has a degree of freedom in the XY plane. Therefore, in order to restrain the degree of freedom and stabilize the squeegee holder during printing, the holder mounting means has a holder restraining mechanism. You must prepare. The holder restraining mechanism is not particularly limited as long as it is a structure that acts when the squeegee holder is tilted at a desired angle and pressed downward to move in the printing direction. There is a structure as shown.

  8 and 9, the shape of the protrusion is illustrated as a semicircular square, but the shape of the protrusion and the receiving portion is not particularly limited, and the squeegee holder is held in any of the above three small categories. The shape is not particularly limited as long as it can be mounted on the apparatus main body and can achieve the purpose of maintaining a desired angle during printing.

  The angle setting means is for setting the inclination of the squeegee holder to a desired angle with respect to the printing direction, and the mechanism is classified as shown in FIGS. FIG. 10 and FIG. 11 are assembled views as seen from different angles, wherein the mounting means on the squeegee holder side is used as a protrusion and the mounting means on the holding block side is used as a receiving part. A fan-shaped angle adjusting plate with a screw hole) is used as an angle adjuster, and a screw hole (or hole) is used as an angle-adjustable tool (hereinafter referred to as an angle adjuster). An example of the angle setting means is shown that is fastened and fixed by a knurled screw.

  In the figure, the squeegee holder side mounting means, the holding block side mounting means, the squeegee holder, and the holding block can be classified according to the part where the angle adjuster is provided. The mounting means, the mounting means on the holding block side, the squeegee holder, and the holding block can be classified into four types, and the angle setting means can be implemented by combining them.

In such a state, the squeegee holder and the mounting means on the squeegee holder side may be regarded as an integrated unit. The mounting means on the holding block side is also fixed to the holding block on the XY plane. In such a state, the holding block and the mounting means on the holding block side may be regarded as an integrated unit. Considering the above, (4b) and (1a) in which the angle adjusting plate is provided in the mounting means on the holding block side and the screw hole is provided in the squeegee holder are the same mechanism, and the angle adjusting plate is attached to the holding block.

The mounting means on the holding block side is also fixed to the holding block on the XY plane, and the holding block and the mounting means on the holding block side may be regarded as an integrated unit. Therefore, (3b) and (1b) in which the angle adjusting plate is provided in the mounting means on the squeegee holder side and the hole is provided in the holding block are the same mechanism, and the angle adjusting plate is provided in the squeegee holder and the hole is held in the holding block. It can be said that (4a) provided in the side mounting means and (6b) provided with the angle adjusting plate in the squeegee holder and provided with the hole in the holding block are the same mechanism as (1b).

  Next, (2a), the angle adjusting plate is provided in the squeegee holder, the hole is provided in the mounting means on the squeegee holder side, and the mounting means on the squeegee holder side fitted to the squeegee holder is coupled to the holding block. It is mounted on mounting means on the holding block side and fastened with knurled screws. Here, the attachment means on the squeegee holder side does not rotate when attached to the attachment means on the holding block side, and particularly during printing, it is attached in the direction opposite to the printing direction due to the frictional force between the squeegee and the screen plate. And is fixed to the mounting means on the holding block side in the XY plane.

  Next, in (2b), the angle adjusting plate is provided in the mounting means on the squeegee holder side, the screw hole is provided in the squeegee holder, and the mounting means on the squeegee holder side fitted to the squeegee holder is coupled to the holding block. It is mounted on the mounting means on the holding block side and fastened with knurled screws. Here, the attachment means on the squeegee holder side does not rotate when attached to the attachment means on the holding block side, and particularly during printing, it is attached in the direction opposite to the printing direction due to the frictional force between the squeegee and the screen plate.

It is mounted on mounting means on the holding block that is freely mounted on the shaft, and is fastened and fixed with knurled screws. Here, the mounting means on the squeegee holder side does not rotate when fitted to the squeegee holder, but is fixed to the squeegee holder on the XY plane. Also, it does not rotate even when mounted on the mounting means on the holding block side, and particularly during printing, it is biased in the direction opposite to the printing direction by the frictional force between the squeegee and the screen plate, and the mounting means on the holding block side Are fixed on the XY plane.

  Further, in (5b), the angle adjusting plate is provided in the holding means on the holding block side, and the hole is provided in the holding block, so that the mounting means on the squeegee holder side that is fitted to the squeegee holder can be rotated on the holding block. It is mounted on the mounting means on the holding block that is attached to the shaft, and is fastened and fixed with knurled screws.

  The mechanism of the angle setting means has been described with the mounting means on the squeegee holder side as a protrusion and the mounting means on the holding block side as a receiving part. However, the mounting means on the holding block side as the receiving means on the squeegee holder side. The mechanism of the angle setting means can be classified in the same manner even if the projection is a protrusion.

  In addition to the angle setting means, the angle adjustment tool is an angle adjustment plate, the angle adjustment tool is a screw hole (or hole), and both are engaged and fastened with a knurled screw. However, the method is not particularly limited, and any method may be used as long as an angle adjusting tool having a jagged surface, a projection, a hole, or the like provided at a predetermined angle is fixed to the angle adjusting tool at a desired angle.

  FIG. 12 illustrates several methods of angle setting means. (1) is a method of fixing a gear-shaped angle adjusting tool having a jagged shape at a desired angle with an angle adjusting tool having a claw, and (2) is a disk-shaped angle adjusting tool having a pin hole at a desired angle. And (3) is a method in which an angle adjusting tool having a similar jagged surface is pressed against and fixed to an angle adjusting tool having a radial jagged surface. .

  The angle setting means described and exemplified so far is a method in which the angle adjuster is fixed at a desired angle with respect to the angle adjuster, but the squeegee holder is required to be tilted at the time of printing. Therefore, a method may be used in which the squeegee holder is tilted in the printing direction by the frictional force between the squeegee and the screen plate during printing, and the maximum tilt angle of the squeegee holder during printing is defined by a stopper.

  The mechanism of the angle setting means that defines the maximum tilt angle with the stopper is classified as shown above and is as shown in FIGS. FIG. 13 and FIG. 14 are assembled views seen from different angles. The mounting means on the squeegee holder side is used as a protrusion and the mounting means on the holding block side is used as a receiving part. The angle setting means of the system which prescribes | regulates the maximum inclination angle via a pin is illustrated using the provided fan-shaped angle adjustment board as an angle adjustment tool, and a pin groove as an angled adjustment tool.

  Here, there are a number of methods other than the above for defining the maximum tilt angle of the squeegee holder, and the method is not particularly limited, and an angle having a jagged surface, a projection, a hole, etc. provided at a predetermined angle. Any method may be used as long as the adjustment tool is defined by a desired maximum inclination angle with respect to the angle adjustment tool.

  The mode of the holding portion is realized by combining one mode of the holder mounting unit and one mode of the angle setting unit, and there are various specific modes, and the modes are particularly limited here. Not what you want.

  The height setting means adjusts the height of the squeegee holder at the time of printing. As shown in FIG. 15, the height setting means is a screw that is rotatably suspended at the lower limit contact portion and screwed into the holding portion. By rotating the mechanism, the holding portion moves up and down with respect to the lower limit contact portion, and the interval between the holding portion and the lower limit contact portion can be set as desired. The mechanism for setting the interval is not particularly limited, and it is possible to employ a pawl mechanism, a rack and pinion mechanism, etc. in addition to the screw mechanism in the drawing.

  The upward retracting means is for retracting the holding portion on which the squeegee holder is mounted upward during standby and separating the squeegee from the screen plate. The method slides the lower limit abutting portion as shown in FIG. As shown in FIG. 16, there is a method of elastically biasing the block portion upward using a spring and a method of elastically biasing the slide rail portion upward using a spring as shown in FIG. is there.

  The aspect of the holder pressing means is a grip or a palm button for pressing the holding portion downward during printing. The operator's posture when sliding the squeegee holder in the printing direction is better to grip and press the grip protruding at the top or press the palm button with the palm of the hand than to hold and press the tilted squeegee holder with the hand. Is stable and operability is improved. In FIG. 15, by providing a palm button on the head of the screw mechanism, the pressing force is transmitted to the holding portion into which the screw mechanism is screwed.

  The linear sliding means includes a slide block portion of the holding device main body and a slide rail portion of the sliding rail, and smoothly moves the holding device main body in the printing direction along the slide rail portion. The slide block is composed of a linear guide block, slide guide block, ball spline block, etc. that use a slide ball bearing mechanism, and an oil-free bushing or oil-free slide block that has low sliding friction resistance (good lubricity), oil-free There are slide blocks for guide rails.

  The end detention means retains the holding device main body by a catch mechanism provided at the end of the slide rail portion, and further includes an impact absorbing mechanism that softens the impact when the holding device main body hits the end detaining means. May be. Examples of the end placement means include ball catches, snap locks, magnet catches, door stoppers, roller catches, push latches, etc., and shock absorbing mechanisms using springs, hydraulic / pneumatic shocks, etc. There are elastic bodies such as absorber, rubber and gel.

  Examples of the device fixing means include, but are not limited to, screw fixing, snap lock, fastener, and magnet catch. However, the device fixing means is not particularly limited, and has a function of fixing the rail fixing portion to the screen frame or the screen printing device. That's fine.

  In the squeegee holding device for screen printing according to claim 1, the squeegee angle, which is one of the main factors affecting the ink film thickness and the print line width, can keep the inclination of the squeegee holder in the printing direction constant. Can also be controlled in manual screen printing.

  Compared with the conventional manual screen printing method that controls the printing speed and squeegee pressing force while paying attention to holding the squeegee holder with both hands and keeping the inclination constant, the squeegee holder or the holder pressing means is moved downward. If the printing speed and the squeegee pressing force are controlled while being pressed against each other, there are fewer control factors, and the printing speed and the squeegee pressing force can be easily controlled. In particular, the gripping and pressing method of the holder pressing means provided on the upper part and the pressing method with the palm of the hand are easier and easier to print than holding the squeegee holder tilted in the printing direction and pressing it downward. It is possible to control the speed and squeegee pressing force.

  In thin film electrodes such as fuel cells, lithium ion batteries, and dye-sensitized solar cells, the film thickness and line width greatly affect the electrical characteristics. If necessary, an automatic screen printing device or semi-automatic screen printing device was used, but by attaching a squeegee holding device to the manual screen printing device, the thin film electrode, etc. can be manufactured with low cost and space with less printing material and high accuracy. Can be formed.

Next, the stainless steel pipe on the squeegee side of the squeegee holder is fitted into the U groove and attached. The waiting squeegee holder is urged and retreated upward by a spring and urged vertically by its own weight. Also, during printing, the squeegee holder tilts in the printing direction due to the frictional force between the squeegee and the screen plate, and the other stainless steel pipe is caught in the U-shaped cutout of the squeegee holder holder head, thereby restraining play. Even if is pressed, the squeegee holder does not come off while maintaining the desired angle.

  In the case of reciprocal printing, as shown in FIG. 4, the other stainless steel pipe is restrained by the corresponding squeegee holder holder according to the printing direction for each one-way printing, but in the case of only one-way printing, the corresponding squeegee holder After tightening and fixing only the receiver with the angle fixing screw and mounting the squeegee holder, the other stainless steel pipe may be clamped by the remaining squeegee holder receiver, and the pair of squeegee holder receivers may be coupled by the coupling screw. . At this time, the play of the other stainless steel pipe is restricted and the squeegee holder is fixed.
