Description

  The present specification relates to a component data correction system and a component data correction method for correcting existing component data (part data) used in an existing component mounter into component data usable in another type of component mounter. Is disclosed.

  During operation of the component mounting machine, the component supplied from the feeder is picked up by the suction nozzle and transported to the mounting position. The result of the recognition is compared with part data created in advance to determine whether the part is normal or abnormal, and the part determined to be abnormal is discarded at a predetermined disposal location and determined to be normal. Only the components are mounted on the circuit board. Here, the component data includes, for example, the size of the component body (dimensions in the X, Y, Z directions, etc.), the size of the terminals such as leads, etc. (lead width, length, lead pitch, lead position, number of leads) Etc.) are included. Furthermore, recent component data includes conditions for imaging the component (illumination conditions such as illumination pattern and illumination angle, camera shutter speed, etc.), information on the suction nozzle that sucks the component (nozzle diameter, etc.), and suction nozzle Also includes data related to the speed at which the parts picked up are transported. Refers to the part data by a production job (production program) while the component mounter is in operation, and picks up parts, picks up images, transports, etc. Is to control.

  As described in Patent Document 1 (Japanese Patent Laid-Open No. 2011-211088), a conventional method for creating part data includes product specifications such as dimensions and the number of leads described in a part catalog and CAD data for parts. To create part data manually by an operator, or use a parts data creation system to capture a part with a camera and perform image processing to automatically create part data. There is something that was made.

JP 2011-211088 A

  By the way, since component data is created for each model of component mounter and may not be compatible, when a new model of the same or different manufacturer is introduced that is not compatible with the model used by the user, Parts data suitable for the new model is required. In this case, it may be possible to re-create the part data suitable for the new model, but it takes time and effort to create reliable part data, so if there is existing part data with production results In many cases, the existing parts data is modified to match the specifications of the new model. Currently, when modifying existing part data, an operator skilled in creating part data relies on experience to manually correct the part data. For this reason, the reliability of the corrected component data depends on the skill level of the worker, and if the skill level of the worker is low, the component data is not corrected properly, and a component pick-up error occurs while the component mounter is in operation. There is a problem that the frequency of occurrence of troubles such as image processing errors increases and productivity decreases.

  In order to solve the above problems, a component data correction system for correcting existing component data used in an existing component mounter into component data usable in another type of component mounter, the component body and the terminal A part data creation unit that automatically creates part data based on part information including information about the existing part data is compared with the automatically created part data and the existing part data is converted based on the comparison result. In this configuration, a component data correction unit that corrects the component data to be usable by another type of component mounter is provided.

  In this configuration, using the part data automatically created based on the part information including information on the part body and the terminal, the existing part data is corrected to the part data that can be used by another type of component mounter. Therefore, the existing component data can be corrected to component data suitable for a different type of component mounting machine without depending on the skill level of the operator, and the quality of the corrected component data can be improved. In addition to the information about the part body and the terminal, the part information may include information about the part weight that affects the conveyance speed of the part, but the part weight can be estimated from the information about the part body and the terminal. Information on the part weight may not be included.

  In this case, the part data correction unit displays the existing part data and the automatically created part data on a display device for comparison, and an operator determines whether correction is necessary and inputs the determination result. When the operator determines that correction is not necessary, the existing component data is not corrected, but is used as component data that can be used on the component mounting machine of another model as it is, and the operator determines that correction is necessary. However, the existing component data may be corrected to component data that can be used by the another type of component mounter. In this way, it is possible to leave the determination of whether or not the existing part data needs to be corrected to the operator's judgment, and the operator's judgment can be reflected in the correction of the existing part data. It should be noted that the determination of whether or not the existing part data needs to be corrected may be automated.

  In addition, when the part data correction unit corrects the existing part data, among the data of a plurality of items included in the existing part data, the data of the item to be corrected is included in the automatically created part data You may make it replace with the data of the applicable item.

  Furthermore, the component data correction unit relates to a component body and terminals (for example, leads, bumps, electrodes, etc.) among a plurality of items of data included in the existing component data when the existing component data is corrected. The data of the item may not be corrected, and the data of at least one item among other items may be corrected. Even if there is no compatibility with the existing part data, the data of the shape item related to the part body and terminal is small, so the data of the corresponding item of the existing part data with production results is used as it is. This is because it seems that there are many cases where the component data is more reliable.

  Specifically, in the existing part data and the automatically created part data, in addition to data on items relating to the part body and the terminal, at least conditions for imaging the part (for example, an illumination pattern, an illumination angle, etc.) Data on three items relating to illumination conditions, imaging conditions such as camera shutter speed, image processing conditions such as image processing algorithms), a suction nozzle that picks up parts, and a speed at which the parts picked up by the suction nozzle are conveyed, The component data correction unit corrects data of at least one item out of the three items among a plurality of items of data included in the existing component data when correcting the existing component data. You may do it. Depending on the model of the component mounting machine, the specifications of the lighting device and camera may differ, or the types of suction nozzles that can be used (nozzle diameter, etc.) and the component suction capacity may vary. And by correcting the data of at least one item among the three items related to the component conveyance speed, the existing component data can be corrected to the component data suitable for the component mounting machine of another model.

  In addition, the information acquisition unit for acquiring the information related to the specifications of the component mounting machine of another model and the component information including information related to the component body and the terminal by omitting the component data generating unit that automatically generates the component data; Component data correction that corrects the existing component data into component data that can be used by the component mounter of another model based on the component information acquired by the component and information regarding the specifications of the component mounter of another model It is good also as a structure provided with the part.

  In short, if there is part information including information on the part body and terminals and information on the specifications of another type of component mounter that uses the corrected part data, the data of multiple items included in the existing part data Among them, the data of three items related to the conditions for imaging the component, the suction nozzle and the conveyance speed of the component can be appropriately corrected based on the component information and the information related to the specifications of the component mounting machine of another model. .

  Hereinafter, two Examples 1 and 2 will be described.

A first embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the component data correction system includes a computer 11 such as a personal computer, an input device 13 such as a keyboard, a mouse, and a touch panel, a display device 14 such as a liquid crystal display and a CRT, and a component shown in FIG. The storage device 15 includes a data correction program and various types of data. The component data correction system may be configured using a component mounter control system, a component mounting line production management system in which a plurality of component mounters are arranged, or May be a dedicated parts data correction system configured separately from these systems. Of course, an automatic part data creation system may be used as the part data correction system.

  The computer 11 automatically creates component data based on the component information including information on the body and terminals of the components necessary for the production of the component mounting board by executing a component data correction program of FIG. Functions as a “part data comparison display part” for comparing and displaying the existing part data used by the existing part mounter and the automatically created part data on the display device 14, and further automatically creating It also functions as a “component data correction unit” that corrects existing component data to component data that can be used by another type of component mounter using the component data thus obtained. Each of these functions will be described below with reference to FIGS. 2 to 4 are diagrams for explaining each function using component data of components with leads.

[Function as part data creation unit]
For the components necessary for the production of the component mounting board, the component information (see FIG. 2) provided by the manufacturer of the components is read into the computer 11. The component information is linked with the CAD data of the component and includes at least information regarding the component body, the terminal, and the component weight. Since the part weight that affects the part conveyance speed can be estimated from information on the part body and terminals, the part information may not include information on the part weight, but information on the part weight is included. Needless to say.

  As shown in FIG. 2, the information related to the component body is data on the size of the component body (such as dimensions in the X, Y, and Z directions). The information on the terminal is, for example, data such as lead width, length, lead pitch, lead position, number of leads, etc. for a leaded component, and bump diameter, bump pitch, bump number, etc. for a BGA component. Data such as position and number of bumps. This component information may be stored in the storage device 15 in advance, or may be downloaded from an external server or the like via a network when necessary, or a recording medium such as a CD on which component information is recorded. May be obtained and read by the computer 11.

  The computer 11 automatically creates part data based on the part information. In the automatically created parts data, as well as the existing parts data, in addition to the data on the items related to the terminals such as the parts body and leads, at least the conditions for imaging the parts, the suction nozzle for picking up the parts, and the suction nozzle Three items of data relating to the conveyance speed for conveying the sucked parts are included.

  Specifically, the item data relating to the component body is the data of the size of the component body (X, Y, Z direction dimensions, etc.), and the item data relating to the terminal is, for example, a lead for a leaded component. Data such as the width, length, lead pitch, lead position, and number of leads. The data of the item regarding the conditions for imaging the component includes, for example, illumination conditions such as an illumination pattern and an illumination angle, imaging conditions such as a shutter speed of a component imaging camera of the component mounter, and image processing conditions such as an image processing algorithm. It is data about. The data on the item related to the suction nozzle that picks up the component is data related to the nozzle type such as the nozzle diameter (nozzle size) of the suction nozzle, and the data on the item related to the transport speed for transporting the component picks up the component supplied from the feeder This is data on the conveyance speed when adsorbing to the nozzle and conveying it to the imaging position or mounting position. The conveyance speed can be set in multiple stages, such as high speed, medium speed, low speed, etc., or infinitely. ing.

  In this case, the algorithm for automatically creating the component data based on the component information (the component data automatic creation program) is a specification of another type of component mounter that uses the corrected component data (particularly, the lighting device that illuminates the component) In consideration of the component imaging camera, the image processing function, the nozzle type such as the nozzle diameter of the usable suction nozzle, the component suction capability for each suction nozzle, the specifications for the mounting head moving device, etc.) Part data corresponding to the specification is automatically created.

[Function as part data comparison display section]
As shown in FIG. 3, the computer 11 compares and displays the existing component data used in the existing component mounter and the automatically created component data on the display device 14. At this time, the existing part data may be stored in the storage device 15 in advance, downloaded from an external server or the like via a network, or a CD or the like on which the existing part data is recorded. A recording medium may be obtained and read by the computer 11.

  The display example of FIG. 3 is a display example in which existing part data related to a leaded part and the automatically created part data are compared and displayed. In the display example of FIG. 3, the data of each item of the body size, the lead size, the nozzle size, and the conveyance speed is different between the existing part data and the automatically created part data.

[Function as part data correction unit]
The worker refers to the existing part data that is displayed in comparison with the display device 14 and the automatically created part data, and the worker determines whether or not the data of each item of the existing part data needs to be corrected. The determination result is input to the computer 11 by operating the input device 13. As shown in FIG. 4, the computer 11 uses the data of the item that the operator has determined that correction is unnecessary, as it is, without modifying the data of the corresponding item of the existing component data, as it is in another type of component mounting machine. Use as possible data, and replace only the data of the items that the operator has determined that correction is necessary, by replacing the data of the corresponding items of the existing part data with the data of the corresponding items of the automatically created part data. Modify the component data so that it can be used with another type of component mounter.

  In this case, when correcting the existing part data, among the data of a plurality of items included in the existing part data, conditions for imaging the part (for example, illumination conditions such as illumination pattern and illumination angle, camera shutter speed, etc.) Imaging data, image processing conditions such as an image processing algorithm), data of at least one item among the three items related to the suction nozzle and the conveyance speed may be corrected. Depending on the model of the component mounting machine, the specifications of the lighting device and the camera for imaging the component may differ, and the types of suction nozzles that can be used (nozzle diameter, etc.) and the component suction capability may differ, so the part is imaged. By correcting the data of at least one of the three items related to the conditions, the suction nozzle and the conveyance speed, the existing component data can be corrected to the component data suitable for the component mounting machine of another model. .

  In the example of FIG. 4, among items whose data differs between the existing part data and the automatically created part data, the worker does not correct the data of the corresponding item of the existing part data for the body size and the lead size. Therefore, only the data of the two items of the nozzle size and the conveyance speed are replaced with the data of the corresponding item of the automatically created component data. Here, the reason why the operator decided not to correct the data of the body size and the lead size is that the data of these shape items is small because there is little difference between the models. This is because it is often the case that the data of the corresponding item of the component data is used as it is, and the component data is highly reliable.

  The component data correction of the first embodiment described above is executed by the computer 11 as follows according to the component data correction program of FIG. When this program is started, first, in step 101, existing component data used by an existing component mounter is read. At this time, the existing part data may be stored in the storage device 15 in advance, downloaded from an external server or the like via a network, or a CD or the like on which the existing part data is recorded. A recording medium may be obtained and read by the computer 11.

  Thereafter, the process proceeds to step 102, and component information relating to components necessary for production of the component mounting board is read. At this time, the part information may be stored in the storage device 15 in advance, or may be downloaded from an external server or the like via a network, or a recording medium such as a CD on which the part information is recorded is obtained. Then, it may be read by the computer 11.

  Thereafter, the process proceeds to step 103, where the specifications of the component mounter that uses the corrected component data (particularly the illumination device that illuminates the component, the camera for imaging the component, the image processing function, the nozzle diameter of the usable suction nozzle, etc. In consideration of the nozzle type, the component suction capability for each suction nozzle, and the specifications related to the mounting head moving device), the component data corresponding to the specifications of the component mounting machine is automatically created based on the component information.

  Thereafter, the process proceeds to step 104, where the existing part data and the automatically created part data are displayed on the display device 14, and the data of each item is compared to extract data of items having different values between the two. Then, in the next step 105, data of items having different values between them is displayed on the display device 14. Or, in order to make it easy to distinguish the data of items with different values from the data of other items, make the data of the items stand out by character modification such as color coding, emphasis, enclosing, shading, etc. Also good.

  Thereafter, the process proceeds to step 106, where the operator looks at the display on the display device 14, determines whether or not the data of each item of the existing component data needs to be corrected, and operates the input device 13 on the determination result to operate the computer. Wait until input to 11. Thereafter, when the operator inputs the determination result to the computer 11, the process proceeds to step 107, where it is determined whether or not the existing part data is to be corrected based on the operator's determination result, and the existing part data is corrected. If this is the case, the process proceeds to step 108, and only the data of the item that the operator has determined to be corrected is replaced with the data of the corresponding item of the existing part data by replacing the data of the corresponding item with the automatically created part data. Correct this program by correcting the data to component data that can be used by another type of component mounter.

  On the other hand, if it is determined in step 107 that it is not necessary to modify the existing component data, the process proceeds to step 109, and the component mounter of another model is directly used without correcting the data of the corresponding item in the existing component data. But use it as usable data and modify this program.

  According to the first embodiment described above, a component that can be used with another component mounter using existing component data by using component data that is automatically created based on component information including information on the component body and terminals. Because the data is modified, existing component data can be modified to component data suitable for a different type of component mounter without depending on the skill level of the worker. Quality can be improved.

  Moreover, in the first embodiment, the existing part data and the automatically created part data are compared and displayed on the display device 14, the operator determines whether correction is necessary, and inputs the determination result. If it is determined that correction is not necessary, the existing part data is not corrected and is used as part data that can be used on another type of component mounter. Since the data is modified to component data that can be used by another type of component mounter, it is possible to leave the judgment of the necessity of modification of the existing component data to the operator's judgment, and the existing component data The operator's judgment can be reflected in the correction. However, the present invention may also automate the determination of whether or not existing part data needs to be corrected.

  In the first embodiment, when the existing part data is corrected, among the data of a plurality of items included in the existing part data, the corresponding item included in the part data that is automatically generated is the data of the item to be corrected. For example, the difference between the correction item data of the existing component data and the corresponding item data of the automatically created component data is corrected (multiplied) by a predetermined coefficient K (0 <K <1). The existing part data may be corrected by adding the value to the correction item data of the existing part data.

  In the example of FIG. 4, the data of the two items of the body size and the lead size is not corrected, but the data of the two items of the body size and the lead size is corrected as necessary. You may do it.

  Next, Embodiment 2 of the present invention will be described with reference to FIG. However, description of the substantially same parts as those in the first embodiment will be omitted or simplified, and different parts will be mainly described.

  In the first embodiment, part data is automatically created based on the part information, the existing part data is compared with the automatically created part data, and the existing part data is converted to another model based on the comparison result. In the second embodiment, the processing for automatically creating the component data is omitted based on the component information, and the computer 11 stores information on the component body and the terminal. Functions as an information acquisition unit that acquires component information and information on the specifications of another type of component mounter, and the component information acquired by the information acquisition unit and information on the specifications of the component mounter of another model This also functions as a component data correction unit that corrects existing component data to component data that can be used by another type of component mounter. Since the part weight that affects the part conveyance speed can be estimated from the information about the part body and the terminal, the part information may not include the information about the part weight, but the information about the part weight is included. Needless to say.

  In short, if there is part information including information on the part body and terminals and information on the specifications of another type of component mounter that uses the corrected part data, the data of multiple items included in the existing part data Among them, the data of three items related to the conditions for imaging the component, the suction nozzle and the conveyance speed of the component can be appropriately corrected based on the component information and the information related to the specifications of the component mounting machine of another model. .

  The correction of the component data of the second embodiment is executed by the computer 11 as follows according to the component data correction program of FIG. When this program is started, first, in step 201, existing component data used in an existing component mounter is read, and in the next step 202, component information relating to components necessary for production of a component mounting board is read. Thereafter, the process proceeds to step 203, where the specifications of another type of component mounter that uses the corrected component data (particularly, the illumination device that illuminates the component, the camera for imaging the component, the image processing function, and the usable suction nozzle) The nozzle type such as the nozzle diameter, the component suction capacity for each suction nozzle, and the specifications regarding the mounting head moving device) are read.

Thereafter, the process proceeds to step 204, and data of at least one item is selected from the data of the three items related to the imaging condition of the component, the suction nozzle and the conveyance speed among the data of the plurality of items included in the existing component data. The correction is made based on the component information and the information related to the specifications of the component mounting machine of another type. Note that data of items other than the above three items may be corrected.
In the second embodiment described above, the same effect as that of the first embodiment can be obtained.

  Compare the specifications of the existing component mounter with the specifications of another model of the component mounter that uses the corrected component data, and based on the comparison results, The data of the item to be corrected may be selected from the item data, and the data of the item may be corrected based on the component information and the information regarding the specifications of the component mounting machine of another model.

  In addition, it goes without saying that the present invention is not limited to the first and second embodiments, and can be implemented with various modifications without departing from the scope of the invention.
