The present invention relates to display manufacturing equipment, and more particularly to a paste applicator.

BACKGROUND ART In a liquid crystal display device, a device for applying a paste such as a phosphor material in a sealant, a liquid crystal, or a plasma display panel (PDP) is known. These devices drive the application head relative to the substrate placed on the stage while quantitatively discharging the paste onto the substrate placed on the stage in accordance with a given application pattern. The applicator produced by the applicant is driven in the Y axis direction with the stage driven in the Y axis direction with respect to the application head, and the application head is driven in the X axis direction on the application head support provided on the stage. An applicator produced by another company is driven in the Y axis direction with respect to the stage on which the application head support is fixed, and the application head is driven in the X axis direction on the application head support.

Since the application head support of the applicator is provided with a plurality of application heads, a plurality of patterns can be applied at once. Each of the plurality of application heads starts the application once and draws a straight line, curve or closed curve and stops the application. At this time, the coating patterns drawn by a single brush at the same time by the plurality of coating heads are called unit coating patterns. It should be understood that the unit coating pattern may vary depending on the number of heads installed on the application head support or the number of heads used for the actual application even though the application pattern is the same overall.

Actual substrate processing is done procedurally. Therefore, it is necessary to accurately understand the time required for the paste application process, which is part of the overall process. In the related art, the time required for paste application was manually calculated by assigning a developer directly to a formula. However, this conventional method not only has a possibility of error but also has a problem that it takes a long time because the application time must be recalculated if there is a change in any element value included in the formula.

The present invention is derived from such a background, and an object thereof is to conveniently confirm the paste application result according to the application pattern and application condition information set in the paste applicator.

Furthermore, an object of the present invention is to calculate the paste application time quickly and accurately.

The paste simulation coating apparatus according to an aspect of the present invention for achieving the above object simulates the situation that the application of the paste proceeds on the application pattern in accordance with the application pattern information and the application condition information input through the information input means generated And generating and outputting simulation application screen data.

According to the present invention according to this aspect of the present invention, it is possible to accurately grasp the set contents by simulating a situation in which the paste is applied according to the application pattern data and the application condition information set in the actual paste applicator.

According to a further aspect of the present invention, the time required to obtain the movement time of the application head by dividing the length of each application pattern by the corresponding application speed for the entire application pattern from the application pattern data and application condition information, and the time required to rotate at each break point and It is characterized by calculating the time required for the entire application, including the value obtained by adding the movement time between the patterns, and outputting it.

According to this aspect, the paste application time for the whole pattern can be calculated quickly and accurately.

The foregoing and further aspects of the present invention will become more apparent through the following embodiments. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

1 is a block diagram schematically showing a paste simulation coating apparatus for a paste applicator according to an embodiment of the present invention. In one embodiment, the apparatus for generating the coating pattern data according to the present invention may be implemented in a personal computer that is integrally provided with the paste applicator or that is separate from the equipment.

In the present embodiment, the paste simulation coating apparatus according to the present invention includes a pattern data input means 110 for receiving application pattern data, information input means 100 for receiving application condition information including an application speed, and a pattern. Simulation application screen generation means for generating and outputting simulation application screen data for simulating application of paste according to application pattern data input through data input means 110 and application condition information input through information input means 100. 130.

In addition, the illustrated data storage means 120 may be implemented as a memory provided in a personal computer, for example, a hard disk, a nonvolatile semiconductor memory, or the like. In the present embodiment, the data storage means 120 stores the pattern data information input to the pattern data input means 110. In addition, the data storage means 120 may store application condition information such as application speed and pressure input through the information input means 100.

The pattern data input unit 110 receives the pattern data. The pattern data may be input numerically directly through a keyboard or in a form stored in a recording medium such as a diskette. In the present embodiment, the pattern data input means 110 is interpreted to encompass all of the configurations for receiving data in other forms and generating pattern data therefrom.

In one embodiment, the pattern data input means 110 may read drawing data of the coating pattern. In this case, the pattern data input unit 110 is a means for receiving a file including drawing data. For example, the pattern data input unit 110 may be a disk driver mounted on a computer, a removable storage device, or a wired or wireless network. In the present embodiment, the writing data of the coating pattern input to the pattern data input means 110 is a file in which an expert draws a coating pattern shape using a drawing tool, for example, a CAD file created using a CAD tool. Can be.

In the present embodiment, the drawing data is a graphic drawing of the application pattern on the CAD tool together with descriptive information about the application pattern graphic. The CAD file may be in various forms, but most of the graphic layers represent objects such as curves or straight lines as objects, and include additional information about individual figures. Each object is often represented in vector graphics to maintain resolution even when zooming in and out. In the case of coating patterns, it is common to include only very simple figures such as squares, straight lines, circles, and curves. Therefore, the drawing data of the application pattern includes the coordinates of several relatively simple broken points, the connection relationship between these broken points, the radius of the circle and the coordinates of the center point.

The pattern data input means 110 generates pattern data from drawing data of the input coating pattern. First, the pattern data generating unit 110 receives the start point coordinates of the corresponding coating pattern and optionally the end point coordinates from the user. The start point coordinate is a position where the application head first discharges the paste, and the end point coordinate is a position where the application head finishes the discharge while finally discharging the paste. The input of the starting point and the ending point coordinates may be made numerically by the keyboard, or may be graphically input by the mouse. The start point and the end point may be the same point. In another case, the end point may be a position past the start point.

The application pattern data used in the paste applicator is information on the relative movement path of the substrate and the nozzle. This information includes the coordinate values of the points bent from the start point set by the user and the coordinate values of the end point. In the present specification, the reference point is defined as any one of these start points, respective break points, and end points. The coordinate values of the respective reference points are expressed as relative coordinates with respect to the coordinate value of the previous reference point. 6 is an example of drawing data of an application pattern according to an embodiment of the present invention. For example, in the case of the pattern illustrated in FIG. 6, the coordinates of the start point B, the break points P, Q, R, S, and the end point E are shown as B (0,0), P (50,0), Q, respectively. It is called (50,100), R (-50,100), S (-50,0), and E (0,0). These absolute coordinates can be obtained from the CAD file. The pattern data is a permutation of coordinate values, each of which represents an increment relative to the previous reference point. Relative coordinates of point P with respect to point B, the point P is advanced by 50 in the positive direction on the X axis with respect to the point B, the relative coordinate is P (50, 0) because there is no change in the Y axis direction. The point Q has no change in the X-axis direction and has advanced 100 in the Y-axis direction with respect to the point P, so the relative coordinate is Q (0,100). In this way, R (-100,0), S (0, -100), E (50,0), and the pattern data is (0,0), (50,0), (0,100), (-100,0), (0, -100), (50,0). In addition, the pattern data includes the radius of curvature at each corner. In each curve, the curve actually drawn by the application head is automatically determined inside the machine, and the application pattern data includes only the radius of curvature. This radius of curvature is also assigned a default value, which is usually determined by the characteristics of the equipment.

The information input means 100 is a means for a user to input data or a command to a computer. For example, the information input means 100 may be a keyboard, a mouse, or a touch input device. In the present embodiment, the information input means 100 receives from the user input paste application condition information including data necessary for driving the applicator, for example, application speed, application height, application pressure, and the like.

The simulation application screen generating means 130 performs simulation application screen data simulating the application of the paste according to the application pattern data input through the pattern data input means 110 and the application condition information input through the information input means 100. Create and print

According to a characteristic aspect of the present invention, the simulation application screen generating means 130 according to the present invention includes a graphic image generating means 132 for generating a graphic image in the form of an actual application pattern according to the pattern data, and the input application condition information. Simulated application graphic image that simulates paste application to the end point by repeating the trajectory applied on the screen from the starting point to the next reference point at the included application speed, and drawing a curve according to the set radius of curvature and moving to the next reference point again. An image synthesis for generating an output screen including a simulated application image generating means 134 and a simulated application image generated by the simulation application image generation means 134 in a graphic image generated by the graphic image generation means 132. Means 136.

The graphic image generating means 132 reads the application pattern data information, and draws a figure such as a straight line, a curve, or a rectangle, and outputs the image data corresponding to the application pattern as a graphic layer.

The simulated application image generating means 134 reads the pattern data information, and thereby generates a simulated application graphic layer which simulates the paste. In this embodiment, the simulation application image generating means 134 draws a trajectory moving from the starting point to the next reference point in proportion to the application speed included in the input application condition information, and draws a curve according to the set radius of curvature and then again the next reference point. Iteratively draws a trajectory that moves to create a simulated application graphical image that simulates paste application to the end point. Obviously, drawing the trajectory is done by filling in the pixels of the screen to be output to the monitor. In this embodiment, the simulated application image is preferably displayed to be thicker than the graphic image of the application pattern generated by the graphic image generation means 132. For example, when the application pattern is shown by the line of 1 pixel in the image data generated by the graphic image generating means 132, the simulated application image generating means 134 displays the simulated application state by the line of 5 pixels.

The simulation application image generating means 134 determines the ratio of the length of the pattern on the actual substrate and the number of pixels on the screen to generate a graphic image to which the paste is applied so as to correspond to the speed at which the actual paste is applied. For example, suppose the application speed is set to 70 mm / s. At this time, the greater the application speed, the faster the paste coating operation can be performed. However, if the paste application speed is high, the motor response is poor at the time of paste application stop, and the finish is not neat. Therefore, the application speed is preferably set by the developer at an appropriate speed. In this embodiment, the paste is applied while advancing at a speed of 70 mm per second on the actual substrate and can be drawn as a coated graphic image by filling out 10 pixels per second on the screen. In other words, a simulated coating graphic image is generated by filling 10 * 5 pixels per second in the coating direction from the starting point in accordance with the coating pattern data. When the set application speed is increased to 80 mm, a paste application graphic is generated by filling in 12 * 5 pixels per second. When the application speed set in this way is increased or decreased, the simulated application image generating means 134 increases or decreases the number of pixels filled in one second in proportion to the changed application speed. At this time, according to the user's setting, it is also possible to generate a simulated application image for performing the simulation application at 2 times or 1/2 times the application speed. Accordingly, the developer can feel the change in the actual application speed even in the simulated application state displayed on the screen.

The image synthesizing means 136 outputs by overlaying and synthesizing a plurality of graphic layers including an image in the form of a coating pattern generated by the graphic image generating means 132 and a simulated application graphic image layers generated by the simulation application image generating means. Create a screen image. At this time, the image output by the simulation application image generating means 134 is output as a higher graphic layer than the graphic layer output by the graphic image generating means 132.

Such graphic image generating means 132, mock-coated image generating means 134, and image synthesizing means 136 are generally processed in software by the graphics processor of the graphics card and the frame memory.

The output screen image generated by the image synthesizing means 136 is output to the screen output means 140 such as a monitor and visually displayed.

FIG. 2 is a block diagram schematically showing a paste simulation coating apparatus for a paste applicator according to another embodiment of the present invention. As shown, according to another aspect of the present invention, the paste simulation coating apparatus according to the present invention includes a pattern data input means 110 for receiving application pattern data and information input for receiving application condition information including an application speed.

An application time calculation unit for calculating an application time required for application including a value obtained by adding a time required for rotation at each break point and a time added between the application patterns and the output time to the screen output means 140. 200.

The pattern data input unit 110 receives the pattern data. The pattern data may be input numerically directly through a keyboard or in a form stored in a recording medium such as a diskette. In the present embodiment, the pattern data input means 110 is interpreted to encompass all of the configurations for receiving data in other forms and generating pattern data therefrom.

The information input means 100 is a means for a user to input data or a command to a computer. For example, the information input means 100 may be a keyboard, a mouse, or a touch input device.

In the present embodiment, the coating time calculating unit 200 is a substrate loading time + delay time + (length of coating pattern / coating speed) + (time required to rotate at the break point * number of break points) + nozzle between the patterns The application time can be calculated by the time taken for applying the paste to the entire pattern through the movement time + the time taken out of the substrate.

The delay time is the time taken for the paste to be discharged from the nozzle to the substrate and the time taken for the discharge of the paste to stop completely when the paste application is stopped.

The length of the coating pattern can be calculated by the pattern data.

The pattern data is relative coordinate information for each reference point, and the straight line distance between the two reference points can be calculated from this value.

As shown in FIG. 6, when the absolute coordinates of the two points are R (100, -50) and S (0, -50), the relative coordinates of R to S when converted to pattern data are (-100, 0). ) Relative coordinates are (Sx-Rx, Sy-Ry). And the distance between the two points

It can calculate by an equation. Therefore, the linear distance between the two reference points can be calculated from the application pattern data including the permutation of the relative coordinates with respect to the reference points.

The nozzle movement time between patterns is the end of paste application for the first pattern among the plurality of patterns that can be defined by single stroke, starting from the end of the first pattern and reaching the start of the second pattern to apply the next paste. This is the time it takes for the nozzle to move.
