Abstract

<P>PROBLEM TO BE SOLVED: To provide a data preparation device capable of preparing versatile mount data, and to provide a surface mounter. <P>SOLUTION: A preparation section 25d prepares the mount data 21e based on a common determination value or an individual one. When the common determination value is used, the preparation section 25d determines that simultaneous suction can be made when the interval of a suction position exists within the range of the common determination value. When the common determination value is used, it is determined whether the simultaneous suction can be made based on the range of an assembly error, thus preparing the versatile mount data, where the same mount data are usable to the surface mounter having a different assembly error. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a data creation device that creates mounting data for controlling a mounting operation in a surface mounter, and a surface mounter that performs a mounting operation using the mounting data created by the data creation device.

  Conventionally, an electronic component such as an IC is sucked from an electronic component supply unit by a movable head unit having a suction head, and transferred to a fixed printed board that is carried to a predetermined stop position by a conveyor or the like. A surface mounter (hereinafter referred to as “mounter”) that is mounted at a predetermined position on a printed circuit board is known. Even if this mounting machine is the same model, for example, when the suction head is attached to the head unit or the tape feeder is attached to the component supply unit, the distance between the suction heads becomes larger than a predetermined interval, or the tape feeder The operation program in the mounting operation is changed by an error in the mounting position of the components of the surface mounter (hereinafter referred to as “assembly error”) that occurs during the manufacture of the surface mounter, such as the There are cases where it is necessary. For example, if the spacing between the suction heads varies from mounting machine to mounting machine due to assembly errors, one mounting machine can pick up multiple electronic components at a time, while other mounting machines pick up only one electronic component at a time. There are things that cannot be done.

  In such a case, for example, in the invention described in Patent Document 1, an assembling error of the own apparatus with respect to the centrally managed mounting coordinate data is obtained by input from an operator, and adjustment data and mounting coordinate data including the assembling error are acquired. Based on the above, the component mounting position coordinates are determined and the component is mounted. This eliminates the effects of assembly errors.

JP 2006-80313 A

  However, since assembly errors differ from device to device, the conventional method of creating adjustment data based on the status of the device itself may cause problems if the adjustment data is used with another device of the same type. Even in the same type of device, adjustment data must be created in each device, and this data creation takes time. For this reason, conventionally, it has been desired to create highly versatile control data that can be used not only in its own apparatus but also in other apparatuses as long as they are of the same type.

  Therefore, an object of the present invention is to provide a data creation device and a surface mounter that can create highly versatile control data.

  In order to solve the above-described problems, the data creation device according to the present invention is configured to set the allowable lower limit value and the allowable upper limit value of the mounting position of the component of the surface mounter that sucks and conveys the component and places the component at a predetermined position. It has a 1st acquisition part which acquires the permissible limit value which consists of at least one among them, and a creation part which creates control data which controls operation of a surface mounter based on the acquired permissible limit value .

  The data creation apparatus further includes a second acquisition unit that acquires an actual measurement value of the component of the surface mounter, and a selection unit that selects any one of the allowable lower limit value, the allowable upper limit value, and the actual measurement value. The creation unit may create the mounting data based on the selection result by the selection unit.

  In the data creation device, the allowable limit value is an allowable limit value of an attachment position of the head with respect to a head unit to which a plurality of heads equipped with nozzles for sucking the component are mounted and supported so as to be movable, and the component. You may make it consist of at least one among the allowable limit values of the attachment position of the said feeder with respect to the component supply part to which the several feeder to supply is attached.

  In the data creating apparatus, the allowable limit value may be a combination of an allowable limit value of the head mounting position and a allowable limit value of the feeder mounting position. Here, the allowable limit value is a combination of at least one of an upper limit value of the head mounting position and a lower limit value of the feeder mounting position, and a lower limit value of the head mounting position and an upper limit value of the feeder mounting position. It may be made to become.

  The surface mounter according to the present invention is characterized in that the parts are sucked and transported and placed at a predetermined position based on the control data created by the data creation device.

  According to the present invention, when the control data is created based on the allowable limit value consisting of at least one of the allowable lower limit value and the allowable upper limit value of the mounting position, the value of the mounting position of the component differs depending on the assembly error. Even if it exists, operation | movement can be performed based on common control data. Therefore, highly versatile control data can be created.

  Further, according to the present invention, since the control data is created based on the allowable limit value consisting of at least one of the allowable limit value of the head mounting position and the allowable limit value of the feeder mounting position, the head or feeder With this assembly error, it is possible to prevent a plurality of components from being picked up at one time by a certain surface mounter and only one component from being picked up at a time by other surface mounters.

  In addition, according to the present invention, it is possible to cope with both head and feeder assembly errors by using an allowable limit value composed of a combination of the allowable limit value of the head mounting position and the allowable limit value of the feeder mounting position. It is possible to create mounting data with higher versatility.

  In addition, according to the present invention, by using the control data, even if the mounting position of the component differs due to an assembly error, the component can be sucked and transported and placed at a predetermined position.

For example, as shown in FIG. 4C, the mounted component number indicating the identification number of the electronic component and the identification of the tape that accommodates the corresponding electronic component. The information about the tape number which shows a number, and the feeder number which shows the identification number of the feeder which accommodates the tape of a corresponding electronic component is included. According to the example shown in FIG. 4C, in the component data 162b, an electronic component having a mounted component number “11” is accommodated in a tape having a tape number “11”, and this tape has a feeder number “0002”. ”In the feeder.

(Feeder arrangement data)

For example, as shown in FIG. 4D, the feeder position number indicating the identification number of the feeder attachment position and the feeder identification It contains information about the feeder number indicating the number. According to the example shown in FIG. 4D, the feeder position data 162c indicates that the feeder with the feeder number “0021” is attached to the attachment position with the feeder position number “1”.

(Mounting data)
The mounting data 162d is information used when the electronic component is mounted on the printed board by the head unit 141, and is information indicating the position and order of the electronic components to be mounted. For example, as shown in FIG. 5, a head number indicating the identification number of each head, a suction order indicating the order in which the corresponding heads pick up electronic components, and a feeder identification number in which the corresponding heads pick up electronic components A feeder number indicating a component suction position, a suction position indicating a component suction position of the feeder of the feeder number, a mounting order indicating the order of mounting electronic components sucked by the corresponding head on the substrate, and the corresponding head Information regarding the mounting position indicating the position where the electronic component is mounted and the mounting direction indicating the direction when mounting the electronic component attracted by the corresponding head at a predetermined position on the substrate. This mounting data 162d is a mounting operation by the head unit 141 in which the electronic component is sucked by the component supply unit 13 by the head unit 141, transported onto the substrate, and each electronic component is mounted at a predetermined position on the substrate. It is created every one mounting cycle.

  For example, in FIG. 5, in the first mounting cycle, two heads with head numbers “1” and “4” simultaneously pick up electronic components with the two heads 142 and 142. That is, by moving the head unit 141 in the horizontal direction by the X-axis drive device 144X and the Y-axis drive device 144Y, the head 142 of the head number “1” is moved to the X-axis direction coordinate “300 mm” and the Y-axis direction coordinate “200 mm”. Position above the position (feeding position of feeder number “5”). At this time, the head 142 with the head number “3” is separated from the head 142 with the head number “1” by a nominal pitch of 20 mm in the X-axis direction, so the X-direction coordinate “320 mm” and the Y-direction coordinate “200 mm”. "(The suction position of the feeder number" 7 "). Thereafter, the heads 142 having the head number “1” and the head number “3” are simultaneously lowered and raised by the Z-axis raising and lowering motors, respectively, and suck the electronic components. Subsequently, the head unit 141 is moved in the horizontal direction by the X-axis drive device 144X and the Y-axis drive device 144Y, so that the head 142 with the head number “2” is moved to the suction position (X-direction coordinate “340 mm” with the feeder number “9”). “Y-direction coordinate“ 200 mm ”), the head 142 with the head number“ 2 ”descends and rises to attract the electronic component. Thereafter, in accordance with the suction order, the operation of the head unit 141 to move the head 142 to the suction position and the operation of sucking the electronic component by lowering and raising the corresponding head 142 are sequentially performed. The suction of electronic parts is completed.

  Subsequently, the process proceeds to a mounting process, where the head unit 141 is moved in the horizontal direction by the X-axis drive device 144X and the Y-axis drive device 144Y. During this movement, the component pickup state of each head 142 is sequentially detected by the imaging unit 15, and the amount of displacement of the electronic component relative to the head 142 is calculated. Thereafter, the center of the electronic component attracted to the head 142 with the head number “1” in the mounting order No. 1 is taken into account by taking into account both the positional deviation amounts of the electronic component with respect to the head 142 in the X-axis direction and the Y-axis direction. It is positioned above the mounting position of the direction coordinate “230 mm” and the Y direction coordinate “120 mm”. In parallel with this alignment, the rotation motor is driven and controlled, and the amount of positional deviation in the R direction with respect to the head 142 of the electronic component is taken into account, and the direction of the electronic component is made to coincide with the mounting direction “0 °”. Subsequently, the head 142 is lowered and raised by the Z-axis lifting motor, and the electronic component is mounted on the printed circuit board P at a predetermined mounting position in a predetermined mounting direction. Thereafter, all the remaining electronic components of the head 142 are sequentially mounted on the printed circuit board P by a similar mounting operation in accordance with the mounting order.

  Each of the above information is stored in advance in the storage unit 162, or installed in a control device 16 from a known recording medium such as a CD (Compact Disc) or a DVD (Digital Versatile Disc) and stored in the storage unit 162. May be.

[Operation of data creation device]
In the present embodiment, when the data creation device 2 creates the mounting data 21e, when one nozzle 143 picks up an electronic component from the component supply unit 13 in each mounting cycle of the mounting operation, the other nozzle 143 also uses it. A plurality of nozzles 143 that adsorb electronic components are adsorbed simultaneously (hereinafter referred to as “simultaneous adsorption”), or one nozzle 143 is adsorbed from the component supply unit 13 (hereinafter referred to as “individual adsorption”). Is determined based on a head pitch or a head pitch tolerance preset in the device data 21a. The determination value setting operation for selecting the determination value and the mounting data creation operation for creating mounting data based on the determination value will be described below.

<Judgment value setting operation>
The determination value setting operation will be described with reference to FIG. First, the data acquisition unit 25a acquires production data (step S1). The data acquisition unit 25a may acquire the device data 162a, the component data 162b, the feeder data 162c, and the board data 21b in advance and store them in the storage unit 21. These data include at least data related to the surface mounter included in the production line indicated by the production data.

  When the production data is acquired, the selection unit 25b creates either mounting data 21e used by a single surface mounter 1 or mounting data 21e used by a plurality of surface mounters 1 based on the production data or the like. Is selected (step S2). That is, it is selected whether the mounting data 21e to be created in the future is used in common by the plurality of surface mounters 1 or only used by the single surface mounter 1.

  When creating the mounting data 21e having individuality (step S2: individuality), the setting unit 25c reads the device data 21a of the surface mounter 1 specified by the production data and acquires the value of the pitch between the heads ( Step S3).

  When creating mounting data 21e having commonality (step S2: commonality), the setting unit 25c reads the device data 21a of the surface mounting machine 1 specified by the production data, and acquires the value of the head pitch allowable value. (Step S5). At this time, if it is detected from the production data that a plurality of surface mounters 1 are included in the production line, the setting unit 25c determines the head pitch allowable value of each surface mounter 1 from the device data 21a of the storage unit 21. get.

  When the inter-head pitch or the head pitch allowable value is acquired, the setting unit 25c sets the value as a determination value used for determining whether or not simultaneous suction is performed when creating the mounting data 21e (step S4). Specifically, when the inter-head pitch is acquired, the setting unit 25c sets the inter-head pitch value as a determination value (hereinafter referred to as “individual determination value”). On the other hand, when the allowable head pitch value is acquired, the setting unit 25c sets a determination value (hereinafter referred to as “common determination value”) as follows. When only one head pitch allowable value is acquired, the setting unit 25c sets that value as a determination value. When a plurality of allowable head pitch values are acquired, the setting unit 25c indicates that each head pitch allowable value indicates a range from a lower limit value (= allowable lower limit value) to an upper limit value (= allowable upper limit value). Out of all lower limits, maximum values in all upper limits, minimum values in all lower limits, minimum values in all upper limits, minimum values in all lower limits, and all Either the maximum value among the upper limit values, or the maximum value among all the lower limit values and the minimum value among all the upper limit values is set as the determination value. Which combination is selected is set as appropriate according to an operator's operation input via the input unit 23, an instruction based on production data, an instruction from a host computer on the mounting line via the communication line 3, and the like. By setting a common determination value from such a combination, mounting data can be created according to the type and application of the board to be manufactured and the surface mounter 1 to be used.

  The determination value set by the method as described above is stored in the storage unit 21. Based on this determination value, it is determined whether the mounting data 21e is used in common by a plurality of surface mounters 1 or used by a single surface mounter 1.

<Mounting data creation operation>
Next, the mounting data creation operation will be described with reference to FIG. First, the creation unit 25d reads the determination value from the storage unit 21 (step S11). The creation unit 25d reads the device data 21a, the board data 21b, the component data 21c, and the feeder arrangement data 21d from the storage unit 21 (step S12).

  When the various data are read, the creation unit 25d creates a combination of electronic components (hereinafter referred to as “suction group”) to be suctioned from the component supply unit 13 by the head unit 141 in each mounting cycle in the mounting operation (step S13). . In this suction group, based on the device data 21a, the board data 21b, the component data 21c, and the feeder arrangement data 21d, the mounting operation time is shortened or the electronic components interfere due to the position of the feeder and the mounting position of each electronic component. Combined so that no stable mounting operation can be realized.

  When the suction group is created, the creation unit 25d has electronic components that can be sucked simultaneously among the electronic components included in the suction group based on the determination value, the device data 21a, the component data 21c, and the feeder arrangement data 21d. It is determined whether or not to perform (step S14). Specifically, an electronic component that can extract the position of the feeder 131 to which the electronic components included in the suction group are supplied (hereinafter referred to as a suction position) and can simultaneously suction based on the positional relationship and the determination value. It is determined whether or not exists. A specific example of the determination using the individual determination value and the common determination value will be described below.

(Individual judgment value)
When the individual determination value that is a value obtained by actual measurement for each surface mounter 1 is used, the creation unit 25d determines that simultaneous suction can be performed if the interval between the suction positions is within the range of the individual determination value. . For example, when there are surface mounters 1A and 1B of the same model, the pitch between the heads, that is, the individual determination value is 9 mm for the surface mounter 1A in FIG. The surface mounter 1B is 12 mm, and the creation unit 25d determines that simultaneous suction can be performed when the difference between the suction position interval and the individual determination value is 1 mm or less. At this time, when the interval between the suction positions is 10 mm, it is determined that the surface mounting machine 1A in FIG. 8A can perform simultaneous suction, but the surface mounting machine 1B in FIG. 8B determines that simultaneous suction cannot be performed. Is done. The feeder pitches in FIGS. 8A and 8B are obtained by setting the individual determination value obtained by actual measurement to 10 mm.

  If the individual determination value is used, it is determined whether or not the simultaneous mounting can be performed based on the individual mounting error of the surface mounter 1. Therefore, the simultaneous suction of the electronic components can be performed more stably.

(Common judgment value)
When the common determination value is used, the creation unit 25d determines that simultaneous suction can be performed when the interval between the suction positions is within the range of the common determination value. For example, in FIG. 9, as in the case of FIG. 8, the surface mounter 1A in FIG. 9A and the surface mounter 1B in FIG. It is assumed that the pitch is 9 mm for the surface mounter 1 </ b> A and 12 mm for the surface mounter 1 </ b> B, and the common determination value is 10 ± 2 mm as shown in FIGS. 9 (a) and 9 (b ′). At this time, when the interval between the suction positions is 10 mm, it is determined that simultaneous suction can be performed in both the surface mounter 1A and the surface mounter 1B.

  If it is determined that simultaneous suction can be performed (step S14: YES), the creation unit 25d creates the mounting data 21e so that the corresponding head 142 performs simultaneous suction. According to the example shown in FIG. 5, in the mounting data 21e, the heads 1 and 3 of the suction group with the first mounting cycle have the same suction order as “1”, respectively. It shows that adsorption is performed.

  If the common determination value is used, it is determined whether or not simultaneous suction is possible based on the allowable limit value (at least one of the allowable lower limit value and the allowable upper limit value) of the assembly position. It is possible to create highly versatile mounting data that can be used for different surface mounting machines. Thereby, man-hours for data creation and management can be reduced.

  On the other hand, when it is determined that simultaneous suction cannot be performed (step S14: NO), the creation unit 25d creates the mounting data 21e so that each head performs individual suction without performing simultaneous suction in the corresponding suction group.

  If the determination on whether or not simultaneous adsorption is performed for all the adsorption groups has not been completed (step S16: NO), the creation unit 25d returns to the process of step S13. On the other hand, when the determination as to whether or not simultaneous suction is performed for all suction groups is completed (step S16: YES), the creation unit 25d finishes the mounting data creation operation and stores the created mounting data 21e in the storage unit 21. Remember. The mounting data 21e is sent to the surface mounter 1 via the communication line 3 or a known information recording medium, and stored as mounting data 162d in the storage unit 162. Thereby, the main arithmetic unit 166 of the control device 16 of the surface mounter 1 performs the mounting operation of the electronic component on the printed circuit board P based on the mounting data 162d.

  As described above, according to the present embodiment, when the mounting data is created with the common determination value based on the allowable limit value (at least one of the allowable lower limit value and the allowable upper limit value) of the assembly position, When the mounting operation is performed, the mounting operation can be performed based on the common mounting data even when the value of the predetermined portion is different due to the assembly error. Therefore, highly versatile mounting data can be created.

  Further, according to the present embodiment, it is determined whether simultaneous suction can be performed based on the individual shape of the surface mounter 1 by creating mounting data based on individual determination values based on assembly errors obtained by actual measurement. Therefore, it is possible to create mounting data that can more stably perform simultaneous suction of electronic components.

  Further, according to the present embodiment, mounting data can be selectively created according to the application by selecting either the common determination value or the individual determination value.

  In the present embodiment, the mounting data is created based on the allowable limit value of the assembly position of the head 142. However, the data regarding the arrangement of the feeder 131 is created based on the allowable limit value of the assembly position of the feeder 131. You may make it do. As shown in FIG. 10A, normally, when the feeder 131 is attached to a predetermined attachment position of the component supply unit 13, interference such as contact with or overlapping with the adjacent feeder 131 does not occur. However, when a feeder is attached at a predetermined attachment position due to an assembly error or a processing error, as shown in FIG. Therefore, by setting the attachment position of the feeder based on the allowable limit value of the assembly position of the feeder, it is possible to create data related to the arrangement of the highly versatile feeder 131 that can prevent the feeder 131 from interfering. .

  Further, the mounting data may be created based on a combination of the allowable limit value of the assembly position of the head 142 and the allowable limit value of the assembly position of the feeder 131. In this case, for example, if one is an allowable lower limit value, the other may be an allowable upper limit value. Specifically, for example, a combination of the allowable lower limit value of the allowable limit value of the assembly position of the head 142 and the allowable upper limit value of the allowable limit value of the assembly position of the feeder 131 is combined with the head unit 142 and the feeder 131. It may be used as an allowable limit value. Similarly, the allowable upper limit value of the allowable limit value of the assembly position of the head 142 and the allowable lower limit value of the allowable limit value of the assembly position of the feeder 131 are combined with the allowable limit value of the head unit 142 and the feeder 131. You may make it use as. One allowable limit value may be used as the other allowable limit value. Specifically, for example, the allowable limit value of the assembly position of the head 142 may be set as the allowable limit value of the assembly position of the feeder 131. By doing so, it is possible to create mounting data with higher versatility that can cope with any assembly error of the head 142 and the feeder 131.

  The present invention can be applied to a device and a method for creating an operation program for a device such as a surface mounter in which an assembly error or a machining error occurs at a predetermined location.
