Next, regarding the electrode shape classification, since the number of information is small, only the integral type: 1 gull wing: 2 J lead: 3 flat lead: 4 separation type: 5 insertion type: 6 butt lead: 7 volume: 8 did.

The registration of these electrode shape names is performed by key input. This input can be made in Chinese characters.

A part electronic catalog 2 containing such part text data B and image data IM will be described below.
An example will be described in which the reference numeral 12 is used as a conventional component electronic catalog as described above.

As in the conventional case, when one electronic component that meets the needs can be selected in accordance with a predetermined classification and search procedure, the external view of the selected electronic component, for example, the rectifier diode MA337 is changed. When requested by a command, a screen display as shown in FIG. 33 is performed. On this screen, the outline drawing E including the dimension line of the electronic component and the component text data F which is the dimension corresponding to each dimension line are synthesized and displayed on the screen at the same time. When the size output is selected on this display screen, the component text data B can be output to another.

In response to a request for a land diagram, a screen display as shown in FIG. 34 is performed. On this screen, the outline drawing G including the dimension lines of the lands and the component text data M which is the dimension corresponding to each dimension line are simultaneously displayed on the screen by synthesizing the image data and the component text data. When the size output is selected on this display screen, the component text data H is input to another.

For the requirement of taping dimensions, see FIG.
The screen display as shown in is performed. On this screen, the form diagram I with the dimension line of taping and the part text data J of the dimension corresponding to the dimension line are simultaneously displayed on the screen by synthesizing the image data and the part text data.

In response to a request for a reel size, a screen display as shown in FIG. 36 is performed. Reel drawing K on this screen
And the part text data L corresponding to the dimension line are simultaneously displayed on the screen by synthesizing the image data and the part text data.

If the component text data B of the component includes component text data of component shape, electric capacity, characteristics, mounting machine characteristics, plane gram, substitute component, compatible component of another company, component cost, the mounting data C is created. In order to determine the necessary minimum insulation distance, automatically determine whether there is interference between components when arranging electronic components on a board and determine the required insulation distance based on component shape data, electrical capacitance, and characteristics. It is possible to set a minimum arrangement interval and automatically set an optimum recommended land shape for the electronic component.

Further, by handling the data of the mounting machine characteristics and the plane graph, it is also possible to perform a grouping process for determining the mounting order and arrangement so that various electronic components to be mounted can be mounted more quickly.

Further, by including the data of the replacement part, the parts compatible with other companies, and the cost, the data processing can be performed so that the component having the lowest cost is selected and mounted. At the same time, if a replacement component or another company's compatible component has a different shape or color from the original electronic component, it will be recognized as an erroneous component at the stage of component mounting and error processing will be performed, so an inspection program will be created along with the mounting data creation In this case, the process of rewriting the inspection data can be automatically performed.

Further, if the component text data B includes a code indicating a shape characteristic such as a protruding state of a connection bump on the lower surface of the component, a folding data for mounting the component on the board by the mounting data creation program. The processing for determining the mounting height, the pushing amount, or the pushing pressure can be automatically performed.

The part text data B of the part includes the shape and size, color and color, reflectance,
Presence and condition of lead and cut lead, polarity mark,
Including printed characters such as 1005CR and 10Ω on the component, color code, surface roughness, and surface material, depending on the shape and size of the component, the component recognition method used when mounting the component is either the reflection type or the transmission type. Can be automatically determined. Specifically, a large component is clearly visible even in the transmission method, so that it is easy to recognize correctly. However, a small component is not suitable for the transmission method since the shadow of the nozzle is reflected and only the outer shape can be recognized. Also, small components can be recognized not only by their external shape but also by the leads on the bottom surface when they are recognized by the reflection method, and even if they are mounted using a nozzle with a large diameter, they do not hinder the recognition. is there. Therefore, a large electronic component is determined to be a transmission type, and a small electronic component is determined to be a reflection type, so that there is no erroneous inspection.

Further, a process of changing the amount and type of illumination light for recognizing a part can be automatically performed according to the color, the color and the reflectance, the surface roughness, and the surface material. Specifically, since the mirror surface has high luminance, reflected light cannot be recognized tightly when illuminated with strong light, and cannot be recognized with weak light when the surface is dark. Depending on each surface condition,
Change the optimal light type and light intensity.

Further, processing for confirming and correcting the mounting direction of the component is performed based on the presence / absence and state of the lead and lead cut, and the polarity mark. Further, a process for confirming a mounted component from printed characters and a color code on the component and preventing mounting of an erroneous component can be automatically performed.

When the component text data B includes a plurality of package data that can be adopted for the same type of component,
In the operation of mounting data creation, the form and capacity of the component supply mechanism are determined by the packing form data that can be adopted for the same kind of components, for example, a plurality of data such as taping, tray, and stock, and the characteristic data of the mounting machine 2. Depending on
It is possible to automatically perform a process of determining to adopt a supply format that can be adopted or a supply format that further minimizes the mounting tact time.

Further, the fact that each component supply cassette for each component mounted on the mounting machine 2 has a memory for managing the cassette and the components is used, and the memory is newly provided with the dimensions and colors of the components. And a supply code such as a shape code such as polarity and a packing style, a feed pitch, and a supply direction are written, and it is determined whether or not the part and the cassette match when the part is set in the cassette. To prevent incorrect setting. At the same time, the control unit 102 of the mounting machine 2 equipped with the component supply cassette reads all the information on the various electronic components stored in the memory 104 of each component supply cassette 14, and In addition to being capable of recognizing the arrangement of components, an array library including all of the components read in accordance with the mounting data creation program given to the control means 102,
A component library and a supply library can be generated, and components can be mounted using the library. However, the control unit 102 can also transmit the read component text data B and the like to the data processing device 203 in the first embodiment to provide the mounting data C.

In this case, a special data processing device and data file become unnecessary.

When the component text data B includes shape data such as the height, width, and height of a component, the volume or weight of the component is calculated from these data, and the obtained volume or weight data is used to calculate the volume or weight of the component. Selection of nozzles and chucks that handle, the moving speed of the head with these nozzles and chucks, the table moving speed,
In particular, processing for setting the acceleration and various allowable values can be automatically performed.

The component text data B includes a package color code, a component shape, a recommended land shape of the component,
Include the surface material of the part, the reflectance of the surface (if the reflectance is different for each part such as both ends and the center of the part, the reflectance for each part), polar marks, printed characters and color codes on the part surface In addition, an inspection program for inspecting various components after mounting can be automatically generated corresponding to the components of the mounting data.

Therefore, as in the case of mounting data creation,
There is no need to select and configure electronic components that meet your needs.
Inspection data for each type of component and each type can be obtained by simulating component mounting data.

When the component text data B includes a component shape, in particular, vertical, horizontal, and height sizes, and lead information, the read data in the visual inspection is automatically set in the inspection program based on these. be able to.

If the component text data B includes the temperature characteristics of all the electronic components mounted on the same board, the component mounting data creation program sets the temperature conditions when mounting the electronic components mounted on the board. Processing can be performed automatically. Specifically, when electronic components are mounted on both sides of the board, the electronic component having higher heat resistance than the second surface to be mounted later is set on the first surface to be mounted first.

Thus, the electronic component having high heat resistance mounted on the first surface of the substrate 1 is bonded using reflow solder having a high melting point, and the electronic component having low heat resistance mounted on the second surface is low in melting point. When boarding is performed using reflow solder, the electronic component mounted first on the first surface is melted when the electronic component is mounted on the second surface and reflow soldered, and the mounted electronic component falls, It is possible to prevent the electronic component having low heat resistance from being damaged during reflow soldering when mounting the electronic component on the second surface. A condition program for setting an optimum temperature profile of the reflow soldering apparatus can be automatically created by the data creation processing means 202 using these temperature characteristic data, and is specially created on the side of the reflow soldering apparatus. This eliminates the need for labor and can avoid the occurrence of errors due to the creation of separate data.

As part text data of a part,
When the data on the necessity of burning or refrigeration based on whether or not the component is a moisture-absorbing component is included, the process of generating the handling condition of the component when mounting the component together with the mounting data can be automatically performed.

Further, in order to write various information in the memory 104 or the like by using the read / write means 105 or to update the written contents, the control means 102 uses the number of used components, the remaining amount, Manages various types of mounted component information on mounted components, such as component quality, and component mounting information on component mounting, such as the percentage of components held by chucks and suction nozzles relative to the total number of components supplied, and the percentage of components mounted on a board. Then, at the time of removing the component supply cassette 14 at a time, the read / write means 105 is operated prior to the removal to write the mounted component information and the component mounting information in the storage means or to update the written content. Can also.

As described above, the control means 102 performs various kinds of mounted component information on mounted components, such as the number of used components, the remaining amount, and the quality of the components mounted on the mounting machine, and a chuck for the total number of supplied components. Component mounting information relating to component mounting, such as a component holding ratio by a suction nozzle and a component mounting ratio on a substrate, is managed, and when the component supply cassette 14 is collectively removed, the read / write means 105 is read prior to the removal.
To write the mounted component information or component mounting information in the storage means or update the written content, the number of used components, the remaining number, and various components related to the component to be mounted, such as pass / fail. The component supply cassette to be removed can have information and various information relating to component mounting, such as the component retention rate by the chuck and the suction nozzle with respect to the total number of supplied components, and the mounting rate on the board. As a reference when mounting, the catalog data of the parts and the judgment of the difference between the actual dimensions of the parts can be used, so that more appropriate parts can be supplied, or the mounting conditions can be corrected or changed. This is convenient for comprehensive management of components to be mounted and their mounting states, such as proper mounting, and various measures based on this.

In the case of such data management, when the component supply cassettes 14 are individually attached and detached, a memory 104 can be provided in each of the component supply cassettes 14 and managed individually.
