Description of the invention (1) [Detailed description of the invention] [Technical field to which the invention belongs] The present invention relates to placing a substrate on a table with respect to a discharge port of a nozzle, and maintaining the substrate on a main surface of the substrate The predetermined relative distance between the nozzle and the substrate in the vertical direction enables the solder paste filled in the solder paste storage cylinder to be ejected from the ejection outlet onto the substrate, so that the relative positional relationship between the substrate and the nozzle can be changed. A solder paste applicator for applying a solder paste of a predetermined shape to a substrate, and more particularly to a solder paste applicator capable of improving productivity. [Knowledge technology] It is known that in the solder paste coating machine, as a method to improve productivity, the solder paste filled in the solder paste storage cylinder is ejected from the nozzle side to the substrate, and the relative movement between the nozzle and the substrate is increased. The speed is the speed at which the solder paste is applied (hereinafter, referred to as the coating speed). [Problems to be Solved by the Invention] However, when the solder paste coating machine is a conventional technique as described above, once the coating speed is increased, the straight portion of the solder paste pattern is not a problem, but when the curved portion with a small radius of curvature changes at a right angle in the coating direction That is, for example, when the coating direction is changed from the X-axis direction to the Y-axis direction or from the Y-axis direction to the X-axis direction, the moving part will vibrate. For example, when the moving part is a nozzle and the fixed part is a substrate chuck mounted on a substrate (that is, when the nozzle is moved relative to the substrate), when the nozzle's moving direction is changed, the nozzle produces a vertical (Z-axis) direction or a horizontal ( X, Y axis) direction vibration, especially the vertical direction. The paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) < Please read the precautions on the back before filling this page) '装 · ΤΓ * — Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs -4- 408041 at _ B7_ V. Invention Description (2) (Please read the precautions on the back before filling this page). In addition, when the fixed part is a nozzle and the moving part is a substrate chuck (that is, when the substrate is moved), when the moving direction of the substrate chuck is also changed, the substrate chuck thus causes the substrate mounted on the substrate to generate the same vibration. In particular, vibration in the vertical direction is increased. The above-mentioned vibration is large at the peripheral portion of the substrate, especially at the corner portion. Therefore, a variation in the (relative) distance in the vertical direction occurs between the main surface of the substrate between the nozzle and the substrate, which reduces the coating accuracy. That is, as shown in FIG. 10, the relative (position) distance of the substrate between the nozzles 13a and the substrate 22 varies between 5 and z. Therefore, the amount of solder paste applied per unit time can be changed, and there is no possibility. The problem of coating the solder paste to form a predetermined shape is 2, 3, and the more the coating speed is increased, the larger the change in the relative “position” distance between the nozzle 1 3 a and the substrate 22 is. Therefore, the formation cannot increase the coating speed and cannot increase. The object of the present invention is to provide a solder paste coating machine that can eliminate the above problems, increase the coating speed and increase productivity, and can apply a good predetermined shape of the solder paste pattern. Employees of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by a consumer cooperative [means for solving problems] In order to achieve the above-mentioned purpose, the solder paste coating machine of the present invention is placed on a workbench to form a nozzle opposite to the nozzle outlet, and maintains a vertical direction on the main surface of the substrate. The predetermined distance between the nozzle and the substrate is such that the solder paste filled in the solder paste storage cylinder is discharged from the discharge port onto the substrate, so that the substrate and the substrate of the nozzle are The relative positional relationship of the paper changes, and the characteristics of this paper scale apply to the Chinese national standard (CNS > A4 specification (210X297 mm) -5- 408041) 377 V. Description of the invention (3): (Please read the note on the back before filling out this page) Have a predetermined substrate mounted on the table at a predetermined relative moving speed and the relative positional relationship with the nozzle The first means for detecting the relative distance between the nozzle and the main direction of the main surface of the predetermined substrate perpendicular to the predetermined substrate is changed; determining whether it is the second method for setting the allowable range of the relative distance detected by the first method in advance :. When the relative distance is determined to be outside the allowable range by the second means, a speed reduced by a predetermined amount from the predetermined relative speed is used as the new predetermined relative moving speed, and the new predetermined relative moving speed is used to make the first The third means of means operation; and when the relative distance is judged to be within the allowable range by the second means, in order to draw a solder paste shape of a predetermined shape, a predetermined phase at that time is used. The moving speed is the fourth means of the relative moving speed between the substrate from which the solder paste is discharged from the nozzle discharge port and the nozzle.

Description of the invention (8). In the figure, when the power is first applied to the solder paste applicator of this embodiment (step 100) * the initial setting can be performed (step 200). This initial setting process is shown in Fig. 1. By driving the servo motors 8a, 8b, and 10, the Z-axis moving table is moved to the X and Y axis directions and positioned at a predetermined reference position. 3 a is positioned at the position where the solder paste ejection outlet starts to eject the solder paste (ie, the solder paste application start point), and is set at a predetermined origin position while coating on the substrate (the solder paste pattern is drawn as an object) Hereinafter, the data of each solder paste pattern (hereinafter, referred to as solder paste pattern data) or more than 1 of the actual substrate; or the position data of the actual substrate; between the actual substrate and the nozzle when the solder paste is actually applied on the solid substrate Relative speed (this is called the coating speed, especially the coating speed in this case is called the initial set coating speed) and the nozzle height from the surface of the substrate (this is called the coating height, especially the coating height in this case is called the initial Setting the coating height) and the pressure applied to the solder paste storage cylinder 13 that determines the amount of solder paste discharged from the nozzle (this is called the coating pressure, especially the coating pressure in this case is called the initial setting coating pressure), etc. Separate data; position data showing the completion position of solder paste ejection; and measurement position data such as the pattern of the applied solder paste.

In the process of placing the dummy substrate, the dummy substrates are transported above the substrate chuck 4 by the substrate conveyors 2a and 2b in the X-axis direction. Next, the substrate conveyors 2a and 2b are lowered by a lifting means (not shown). It is placed on the substrate chuck 4. Next, in order to measure the presence or absence of vibration of the movable part during the solder paste application operation, a pseudo solder paste application operation (a solder paste simulation application operation) was performed using this dummy substrate. The purpose of this solder paste simulation coating operation is to detect where the vibration of the movable part occurs when the solder paste pattern is painted on the real substrate, and to obtain the maximum coating speed at which the above-mentioned positional vibration does not occur. The obtained coating speed is the coating height of the coating pressure. In addition, the initial setting coating speed or initial speed coating height and initial setting coating pressure set in the initial setting process and process (step 200) are those who apply solder paste to the determined linear portion of the solder paste pattern based on experience. . The above-mentioned solder paste simulation coating operation printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs measures the presence or absence of vibration from the change in distance between the nozzle 1 3 a and the substrate 2 2 (Figure 2). This system uses an odometer 1 4 as the vibration. Measuring rod tester. In addition, the solder paste patterns used in the solder paste simulation coating operation are η (however, η is generally an integer of 1 or more) solder paste patterns used on a real substrate. As described above, the data of these solder paste patterns are obtained from the keyboard. 19 (Fig. 1) is input, and within the RA M of the microcomputer 17 a (Fig. 3) (hereinafter, referred to as a memory only), for example, 1, 2, ... are given in the order used when the solder paste is applied to a real substrate. η number and stored. When starting the solder paste simulation coating operation, first, position the odometer 1 4 used as a vibration measurement sensor at a predetermined height on the pseudo substrate.

Description of the invention (1〇) ---------- Installation-(Please read the note on the back before filling this page) (Step 400) And, the solder paste pattern data used to simulate the coating operation is selected from the solder paste pattern data stored in the memory, and the number is stored in the memory. Initially, the solder paste pattern data of number 1 is selected (step 5 0 0 ) = Among them, the first microcomputer 17 a (picture 3) is to immediately use the solder pattern data of the selected number 1 to control the servo motors 8 a, 8 b, and 10, so that the nozzle 1 3 a follows the tin of the number 1. The solder paste pattern specified by the paste pattern data is moved at the above-mentioned initial set coating speed, thereby starting the simulated coating operation (step 600). At this time, the solder paste is not ejected from the nozzle 13a, and the servo motor 12 is not controlled. At the same time as the mold coating operation starts, use the odometer 1 4 The distance between the main surface of the substrate 2 2 between the nozzle 1 3 a and the substrate 2 2 and the vertical direction is measured, and the measurement data is used as the distance measurement result in the vertical direction and the position data indicated by the solder paste pattern data are correlated and stored in the memory. (Step 7 0 0). Figure 5 is a detailed flowchart showing the distance measurement processing steps (Step 7 0 0). The consumption cooperation of employees of the Intellectual Property Bureau of the Ministry of Economic Affairs is printed in the same figure, using the distance meter 1 4 in order Measure the distance between the nozzle 1 3 a and the substrate 2 2 (step 7 1 0), and store the result obtained in order as the distance data and the position data in the memory (step 720). The measurement of the distance data. The storage process is continued until the solder paste pattern with the simulated coating action number 1 is completed (step 7 3 ◦) ° When the above-mentioned distance measurement process (step 7 0 0) is completed, the Japanese paper standard is applied to the Chinese standard ( CNS) Α4 specification (210X297mmi, -13-408041) 5. Description of the invention (11) (谙 First read the precautions on the back and then fill out this page) Program 14 retreat to the top (step 8 0 0), The obtained distance data is used to search for the vibration-generating position outside the allowable range, that is, the solder paste application position where the vibration outside the allowable range on the solder paste pattern is generated. Judgment (step 9 0 0). Figure 6 shows the details outside the allowable range. The flowchart of the search processing process (step 9 0 0) of vibration-like appearance. In the same figure, first of all, it is first determined whether there is distance data to be searched. The judgment distance data (step 9 10) is completed. When the distance data is searched. Based on the absence of distance data to be searched and determined, 値 0 is substituted into the variable V_F for the allowable range determination flag (step 950). On the other hand, when the search and determination of the distance * distance data is not completed, the next distance data is read for data conversion (step 920). Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs when the data conversion process is illustrated in Figure 7. Figure 7 (a) shows the distance data (waveform 1) obtained from the distance measurement. The slight expansion of the distance data is false. The expander on the substrate surface does not control the servo motor 12, so the odometer 14 measures the change in the distance between the nozzle 13a and the substrate 22 caused by the expansion. In addition, the drastic change in part a of the distance data is caused by the up-and-down vibration of the odometer 1 4 (hence the nozzle 1 3 a), and the coating speed, that is, the state in which the nozzle moves too fast, when the nozzle 1 3 a Occurs when the moving direction of the In order to determine whether the vibration part shown in Fig. 7 (a) is outside the preset allowable range, the data conversion is performed to show the vibration change amount by removing the change amount caused by the expansion of the pseudo substrate surface in the distance data. One method is the method of differentially processing distance data. The data obtained from the processing is applied to the Chinese standard (CNS) A4 specification (210X297 mm) " -14-__d (\ RCidt JL___ V. Description of the invention (12) It is shown in Figure 7 (b).-(Please read the precautions on the back before filling in this page) Figure 7 (b), the change caused by the expansion of the surface of the dummy substrate (waveform 2) The amount is within the above-mentioned allowable range, so that the amount of change caused by the vibration of the nozzle 1 3 a can be clearly displayed. Step 9 30 in FIG. 6 is based on the distance data of this transformation to determine whether it has a value outside the above-mentioned allowable range. Part b 'As long as there is one part b, the position data of the solder paste pattern data of number 1 forming all part b outside the allowable range can be detected (ie, the solder paste pattern data based on the solder paste pattern data Position), and substitute 値 1 into the variable V — F for the allowable range determination chart (step 940). Furthermore, the above-mentioned determination processing is performed even if the solder paste sample data of the number 1 is completed until the distance data is detected ( Step 9 1 0), if there is no part b outside the allowable range (step 9 3 0), you can substitute 代 1 into the variable V — F for the allowable range determination chart (step 950). Employee Consumer Cooperatives, Bureau of Intellectual Property, Ministry of Economic Affairs Printing In addition, the data conversion method of the above-mentioned distance data is not limited to the above-mentioned differential processing method, but also a differential processing method of the difference between the front and back data, as long as the amount of change caused by the expansion of the surface of the pseudo substrate can be suppressed. The amount of change caused by vibration is obvious, no matter what method is used. _ The above is the step 9 0 of Figure 4. Based on the above initial setting coating speed, the first simulation of the coating speed of the solder paste pattern data of No. 1 is performed. The coating operation detects the position where vibration occurs. The position where vibration does not occur is based on the solder paste pattern data of No. 1. The coating speed when the actual solder paste is applied to the actual substrate is used as the initial setting coating speed. Complete this step 9 0 0 During the processing, it is determined that the variable V — F is the size of this paper. The Chinese national standard (CNS > Α4 specification (210X297 mm)) is applied.

Description of the invention (13) If it is 1 (step 100 0), when it is 1, move to the coating condition correction process (step 11 00). This is illustrated in Figure 8 The process of modifying the coating conditions (step 1 100) is described below. In the same figure, first, the above-mentioned initial set coating speed is reduced by only a predetermined amount to form a new coating speed (step 1110). However, generally, the coating speed is reduced. At the coating speed, a large amount of the solder paste discharge amount per unit moving distance of the nozzles 13a is formed, so a large solder paste pattern width is formed, and the height is increased at the same time, and a predetermined solder paste pattern cannot be obtained. Therefore, by reducing the discharge pressure of the solder paste, that is, by reducing the application pressure, the amount of solder paste discharge can be reduced to form a solder paste pattern having a predetermined shape. As described above, in step 1 1 10, the initial set speed is reduced by only the above-mentioned predetermined amount to form a new coating speed. If it is necessary to change the coating pressure for this new coating speed, the new coating speed is changed. As a criterion for the determination, the application pressure is reduced by a predetermined application amount (step 113 0). Next, it is necessary to determine whether it is necessary to change the nozzle setting height (coating height) at the new coating speed. If it is necessary to change the coating speed, the coating speed is changed in the same way as the coating pressure. Amount of coating height (step 1150). When the above steps 1 1 0 0 are completed, the coating speed, coating pressure, and coating height at the vibration occurrence detected by the first simulated coating operation using the solder paste pattern data of the above number 1 are set to the new coating speed described above. , Coating pressure, coating height. In addition, in Figure 4, the new coating speed from this grade is used. The paper size applies the Chinese Standard (CNS) A4 specification (210X29?

Description of the invention (14) Step 4 of tin tone pattern data with the same coating pressure and coating height 1 The second simulation coating operation was completed as described above. {Please read the note on the back—items before filling out this page.) For the second simulation coating operation, if there is vibration outside the allowable range, use the coating conditions to modify the process (step 1 1 0 0). The coating speed used above is corrected as described above and a new coating speed is reset. At the same time, if necessary, the coating pressure and the coating height can be corrected (steps 1130 and 1150 in FIG. 8). The coating height is changed to the corrected coating speed, coating pressure, and coating height. Therefore, where the vibration is smaller than the allowable range by the second simulated coating operation, the state of the new fishing coating speed, coating pressure, and coating height obtained by the first simulated coating is formed. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs as described above. Once the new coating speed, coating pressure, and coating height are obtained through the second simulation coating operation, use the same number 1 from step 4 0. The third simulation coating operation of the solder paste pattern data is repeated until the variable V-F becomes 値 0 (step 1 0 0 0). As described above, with respect to the solder paste pattern data of No. 1, the application speed, the application pressure, and the application height of each position on the solder paste pattern can be obtained. At this time, the linear portion of the solder paste pattern is allocated to the initial setting coating speed and initial setting coating, and the initial setting height is "the greater the vibration occurs, the smaller the coating speed is allocated", which can correspond to this. To determine the coating pressure and coating height.

At the coating positions S2 and S5, as shown in FIG. 9 (b), the coating speeds 従 initial setting coating speed Vo with respect to these coating positions S2 and S5 are corrected to VI (in this case, it is necessary to The coating pressure was modified from F 0 to F 1, but the coating height may not need to be modified.) With this new coating speed VI, the second simulated coating operation is performed. With this second simulated coating operation, allowance is made at the coating position S 2 In the case of vibration outside the range, as shown in Fig. 9 (c)., The coating speed relative to this coating * position S 2 is corrected from the coating speed V 1 to (at this time, it is not necessary to modify the coating pressure, but it is necessary to adjust the Coating height from H0 It is H1), and the third simulation coating operation is performed at the new coating speed V2. If the third simulation coating operation does not cause vibration outside the allowable range at any application position, the use is completed. The simulated coating operation of the solder paste pattern data of the number 1 determines the coating speed, coating pressure, and coating height of each coating position shown in FIG. 9 (c) with respect to the solder paste pattern data.

(Please read the $ -free note first and then fill out this page.) Therefore, when solder paste is applied at the coating position S 2, no large vibration outside the above-mentioned allowable range will occur in the movable part. When the coating position S 2 is exceeded, the coating speed, coating pressure, and coating height are restored to the original values of ν〇 >, Fo >, Ho. When the coating position S5 is next, the coating speed is changed to V1 by 0. The coating pressure was f 1. Also "while drawing the above solder paste pattern, the microcomputer 17a is inputting the measured data of the distance between the solder paste outlet of the odometer 14 to the nozzle 13a and the surface of the solid substrate" to measure the expansion of the surface of the solid substrate, corresponding In this measurement, the servo motor 12 'is driven to maintain a predetermined height from the surface of the solid substrate to the nozzle 13a to perform coating and drawing of a solder paste pattern. As described above, the painting and drawing of the solder paste pattern are continued, but the operation of continuing the painting and drawing of the solder paste pattern, or the completion of the judgment is based on the judgment of the terminal of the solder paste pattern that should be applied based on whether the application point is the solder paste data. The decision "If it is not the terminal, the measurement processing for the expansion of the surface of the solid substrate is returned again" is repeated below until the coating terminal of the solder paste shape is reached. The coating operation for printing the solder paste pattern by the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is performed on all the solder paste pattern data that has been set. Once it reaches the terminal of the solder paste pattern data of the final number η, it drives The servo motor 12 raises the nozzle 13a to complete the solder paste coating process (step 1660). Next, the process proceeds to a substrate discharge process (step 1700). This process is shown in Figure 1. The solid substrate is desorbed from the substrate chuck 4 and the substrate conveyor 2 a '2 b is lifted to place the solid substrate 2 2 on it. The Chinese national standard (CMS) is applied to this paper scale. ) A4 specifications (21 × 297 public directors) -22- 408041 A7 B7 Printed by the Anti-corruption Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (20) In this state, the substrate conveyor 2 a, 2 b discharge device outer. And, it is determined whether all the above processes have been completed (step 1 800) 'when applying the solder paste pattern with the same solder paste pattern data of a plurality of solid substrates' and repeating the substrate mounting process for other solid substrates (step 1 4 0 ◦ ). In addition, when the related continuous processing is completed for all the real substrates, all the operations are completed (step 1900). Furthermore, in the above-mentioned embodiment, the nozzle is used as the movable portion and the substrate is used as the fixed portion. However, the present invention is not limited to this. The nozzle may be used as the fixed portion and the substrate may be used as the moving portion. As described above, this embodiment uses a pseudo substrate to perform a simulated coating operation 'and determines the coating conditions for the pre-applied solder paste sample data. This eliminates the need to perform unnecessary coating operations on a real substrate and improves its accuracy. In addition, the straight and curved portions corresponding to the solder paste pattern, that is, the shape of the solder paste pattern determines the coating conditions of the real substrate (that is, the coating speed, the coating pressure, and the coating height). Therefore, the coating drawing of the solder paste pattern of the real substrate can be reduced. It is small enough not to affect the shape of the solder paste that depicts the vibration of the movable part (nozzle part or solid substrate), and it can ensure the coating accuracy to maintain a certain amount of solder paste per unit time. Looks like solder paste. In addition, the curved portion of the solder paste pattern is greatly affected by the vibration of the movable portion. Therefore, even if it is impossible to increase the coating speed1, the maximum coating speed without vibration influence can be formed, and the vibration effect of the linear portion is small, so the coating can be improved. speed. In this way, the coating time of the solder paste pattern can be shortened, and a good coating pattern of the solder paste pattern can be performed, thereby improving productivity. In addition, the vibration outside the allowable range of Figure 4 shown in Figure 6 in detail (please read the precautions on the back before filling out this page) The paper size is applicable. National Standard (CNS) A4 Specification (210X297 mm ) -23- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 408041 A7 _ B7 V. Description of the invention (21) In the process of exploring and generating the solder paste appearance (step right 9 0), When the distance data is searched for vibration, there may be no vibration at all. This is the case where a lower coating speed is set in the initial setting. Even faster coating speed may not cause vibration. Therefore, it is also possible to search for the coating process of the vibration generation solder paste outside the tolerance range of FIG. 4 (step 9 0 0). The process of correcting the coating conditions of step 4 shown in detail in FIG. 8 (step 1 1 0 0) The presence or absence of vibration. That is, step 1 1 1 0 of FIG. 8 is to reduce the initial setting coating speed by only preliminarily. It is determined as a new coating speed, but conversely, the initial setting coating speed may be increased only by a predetermined determination and new. Coating speed. In addition, step 1 1 2 0 is to determine whether it is necessary to perform the same pressure change as in Fig. 8. If so, set the volume in step 1 1 3 0 to increase the coating pressure, and step 1 1 4 0 is also to determine whether it is necessary to perform The same coating height is changed in Figure 8. If so, set the amount in step 1 150 to reduce the coating height. As described above, return to step 4 of Figure 4 to step 9 0, and review to what extent the coating speed will increase when vibration occurs. In addition, when the vibration occurs, it should be registered as shown in Figure 9 (c) due to the coating speed immediately before the vibration occurs at the application position (application position). Based on the above, not only can the coating speed limit of the solder paste coating machine immediately before the vibration occurs, but also the time required for one sheet coating can be shortened by increasing the coating speed.
