The control means 102 controls the parts discriminating process according to the flow chart shown in FIG. 22 for the parts which have been collectively replaced, and the micro switch 101 indicates that the transfer table 15 has been attached / detached in step # 1. Only when the determination is made based on the on / off history of, the component determination control of step # 2 and thereafter is executed. Operation panel 1 in step # 2
The selection of the operation mode by the mode selection key on 03 is accepted. The operation mode to be selected is, for example, an operation mode in which the suitability of parts is not determined, all points are selected, or only necessary parts are selected. The parts that need to be identified are those that are out of stock,
The present invention relates to a part or the like which is a switching target due to a change in the type of product, and may be input by an operation on the operation panel 103, or may be automatically designated by the control means 102.

Incidentally, it is also possible to always judge the suitability of the components for all the component supply cassettes 14 without setting the operation mode as described above.

At step # 3, the selected operation mode is determined, and the routine goes to the parts discriminating subroutine at step # 4. As shown in FIG. 23, the parts determination subroutine of step # 4 controls the steps from step # 12 onward only when there is no parts determination in step # 11. In step # 12, the transfer stand 9 of the component supply cassette 14

The mounting machine 2 of the first embodiment has a component inspection means 222 in which an illumination device and a recognition camera are combined in order to determine whether or not the electronic component held by the nozzle 7 or the chuck and the orientation are appropriate. The data for this inspection is generated from the component text data B by the data processing device 203 and included in the mounting data C. Thereby the control means 102 receives it via the data processing device 208,
The suitability of the component can be inspected as a reference for the component discrimination by the inspection means 222. Therefore, proper inspection data can be automatically obtained for the component to be mounted, the required labor and time are the same, and the component can be more properly inspected, and accurate component mounting can be guaranteed.

Since a predetermined number of the component supply cassettes 14 can be collectively handled and exchanged by the transfer table 15, it is convenient for exchanging and replenishing the parts, and the stored part information of each component supply cassette 14 can be transferred to the transfer table. Since the data are collectively provided in the memory 104 or the like provided in 15, and can be read at one place by the reading / writing means 105, the reading does not take time and the productivity is improved. Since the memory 104 can be read and written, it is convenient because the mounting status of the mounting machine 2 can be written and used as a material for component management suitable for the mounting status.

The component supply cassette 14 has a microswitch 101 as a detection means for detecting the attachment / detachment of the component supply cassette 14, and when the control means 102 determines that the component has been replaced from the detection of the attachment / detachment of the component supply cassette 14.

Particularly, when the stored component information is read for all the component supply cassettes 14 in the batch exchange unit that has been exchanged, all the component supply cassettes that have been collectively exchanged are not discriminated and all the component supply cassettes are exchanged. It can be easily dealt with.

It is preferable that the control means 102 has an internal or external storage means for storing substitute part data of a substitute part for a mounting target part or a substitute part such as a compatible companion part. In this way, if the suitability of the part is not suitable, it can be determined whether or not it is the corresponding substitute based on the substitute part data, and even if the substitute part is used when the part runs out. Since it is possible to automatically determine the suitability of the mounted component by automatically responding to this, it is possible to prevent a trouble that is determined as an erroneous component due to the use of the substitute component.

However, CUT0000 is set for the part having the number of cuts of 0.

Next, regarding the electrode shape classification, since there is little information, only one type: 1 gull wing: 2 J lead: 3 flat lead: 4 separate type: 5 insertion type: 6 butt lead: 7 volume: 8 did.

The electrode shape names are registered by key input. This input can be done in Kanji.

Hereinafter, the parts electronic catalog 2 containing such parts text data B and image data IM
An example of using 12 as the above-described conventional electronic component catalog will be described.

Similarly to the conventional case, if one electronic component that meets the needs can be selected according to a predetermined classification and search procedure, an outline drawing of the selected electronic component, for example, the rectifying diode MA337 is displayed. When requested by a command, the screen display as shown in FIG. 33 is performed. On this screen, the outline drawing E with the dimension lines of the electronic component and the component text data F having the dimension corresponding to each dimension line are combined and displayed on the screen at the same time. When the size output is selected on this display screen, the part text data B can be output to another.

In response to the land map request, a screen display as shown in FIG. 34 is performed. On this screen, the outline drawing G with the dimension line of the land and the component text data M that is the dimension corresponding to each dimension line are simultaneously displayed on the screen by combining the image data and the component text data. When the size output is selected on this display screen, the part text data H is also input.

FIG. 35 shows the taping size requirement.
The screen is displayed as shown in. On this screen, the form drawing 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 combining the image data and the part text data.

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

If the component text data B of the component includes the component shape, the electric capacity, the characteristic, the mounting machine characteristic, the plane gram, the substitute component, the component compatible with another company, and the component text data of the component cost, the mounting data C is created. In order to determine the required minimum distance, it automatically determines whether or not there is interference between electronic components when placing electronic components on the board and the required insulation distance based on the component shape data, electric capacity, and characteristics. It is possible to set a limited arrangement interval and automatically set an optimum recommended land shape for the electronic component.

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

Further, by including the data of the alternative parts, the parts compatible with other companies, and the cost, the data processing can be performed so that the mounting with the lowest cost part is selected. At the same time, if the substitute parts and compatible parts of other companies have different shapes and colors from the original electronic parts, they will be recognized as error parts at the stage of mounting the parts and error processing will be performed. However, the process of rewriting the inspection data can be automatically performed.

If the component text data B includes a code indicating a geometrical feature such as the protruding state of the connection bumps on the lower surface of the component, the component data is programmed by the mounting data creation program to mount the component on the board. It is possible to automatically perform the process of determining the mounting height, the pushing amount, or the pushing pressure of the.

As the part text data B of the part, the shape and size of the part, the color and color, the reflectance,
Presence / absence of lead and cut lead, polarity mark,
If the printed characters such as 1005CR, 10Ω on the part, color code, surface roughness, and surface material are included, the method of recognizing the part to be adopted when mounting the part depends on the shape and size of the part. The process of determining whether or not can be performed automatically. Specifically, large parts can be clearly recognized even in the transmissive method, so it is easy to recognize correctly, but small parts are not suitable for the transmissive method because the shadow of the nozzle is reflected and only the outer position can be recognized. In addition, small components can be recognized not only by the 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, this does not hinder the recognition. is there. Therefore, it is possible to determine a large electronic component as a transmissive method and a small electronic component as a reflective method so as to prevent erroneous inspection.

Further, depending on the color and the color and the reflectance, the surface roughness, and the material of the surface, it is possible to automatically perform the process of changing the light quantity and type of the illumination light for recognizing the component. Specifically, since the mirror surface has high brightness, the reflected light cannot be clearly recognized when strong light is applied, and the weak light cannot be recognized when the surface is dark. Depending on each surface condition,
Change the optimum type and amount of light.

Further, processing for confirming and correcting the mounting direction of the component is performed based on the presence / absence and state of leads and lead cuts and the polarity mark. In addition, it is possible to automatically check the mounted component based on the print characters and the color code on the component and automatically perform the process of preventing the mounting of the wrong component.

When the parts text data B includes a plurality of packing style data which can be adopted for the same kind of parts,
In the operation of creating the mounting data, the form and capability of the component supply mechanism can be determined by the packing style data that can be adopted for the same type of component, for example, a plurality of data such as taping, tray, and stock, and the characteristic data of the mounting machine 2. According to
It is possible to automatically perform a process of deciding to adopt a supply format that can be adopted or a supply format that further shortens 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 component, and the size and color of the component are newly added to this memory. , And polarity, and a supply code such as packing style, feed pitch, and supply direction, are written to determine whether the parts match the cassette when setting the parts in the cassette. , Prevent incorrect setting. Along with this, the control means 102 of the mounting machine 2 in which the component supply cassette is mounted reads all the information of various electronic components stored in the memory 104 of each component supply cassette 14, and the component supply unit 8 Besides being able to recognize the arrangement of the parts, an arrangement library including all the read parts according to the mounting data creation program provided to the control means 102,
A parts library and a supply library are generated, and the parts can be mounted by using this. Of course, the control unit 102 can also send the read component text data B and the like to the data processing device 203 in the first embodiment and use it for creating the mounting data C.

In this way, no special data processing device or data file is required.

If the part text data B includes shape data such as vertical, horizontal, and height of the part, the volume or weight of the part is calculated from these data, and the part or volume is calculated from the obtained volume or weight data. Of nozzles and chucks to handle, moving speed of head with these nozzles and chucks, table moving speed,
In particular, processing for setting acceleration and various allowable values can be automatically performed.

As the part text data B, the package color code, the part shape, the recommended land shape of the part,
It includes the surface material of the part, the reflectivity of the surface (if the reflectivity differs between parts such as both ends and the center of the part, the reflectivity of each part), polarity mark, printed characters on the part surface, color code, etc. 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 creating the mounting data,
There is no need to select and configure electronic components that meet your needs.
The types of components and inspection data for each type are obtained by simulating component mounting data.

Further, when the part text data B includes the part shape, especially the size of the length, width and height, and the lead information, the lead data in the appearance inspection is automatically set in the inspection program based on these. be able to.

When the component text data B includes the temperature characteristics of all electronic components to be mounted on the same board, the component mounting data creation program sets a temperature condition for mounting the electronic components to be mounted on the board. The processing can be done automatically. Specifically, when electronic components are mounted on both sides of the board, the first surface to be mounted first is set to have an electronic component having higher heat resistance than the second surface to be mounted later.

As a result, an 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 an electronic component having low heat resistance mounted on the second surface has a low melting point. When the reflow solder is used for the bodging, the electronic component previously mounted on the first surface is melted when the electronic component is mounted on the second surface and the reflow soldering is performed, and the mounted electronic component is dropped. 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. Further, by utilizing these temperature characteristic data, 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, and is specially created on the reflow soldering apparatus side. There is no need for labor and it is possible to avoid the occurrence of errors due to the creation of separate data.

Also, as the part text data of the part,
By including the necessity data of burning and refrigeration depending on whether it is a moisture absorbing component or the like, it is possible to automatically perform a process of generating the handling condition of the component when mounting the component together with the mounting data.

Further, in order to write various information to the memory 104 or the like by using the reading / writing means 105 or to update the writing contents, the control means 102 uses the number of components used by the mounting machine 2, the remaining amount, Manages various mounted component information related to mounted components such as the quality of the component, the component holding ratio by the chuck or the suction nozzle to the total number of supplied components, and the component mounting information related to component mounting such as the mounting ratio to the board. However, when the component supply cassettes 14 are collectively removed, the reading / writing means 105 is operated prior to this removal to write the mounted component information or the component mounting information in the storage means or update the written contents. You can also

As described above, the control means 102 controls various mounted component information such as the number of used components mounted by the mounting machine, the remaining amount, and the quality of the components, and chucks for the total number of components supplied. The component mounting information relating to component mounting such as the component holding rate by the suction nozzle and the board mounting rate is managed, and at the time of batch removal of the component supply cassette 14, the reading / writing means 105 prior to this removal.
To write the mounting component information or component mounting information to the storage means or update the written contents, various components related to the components to be mounted, such as the number of used components to be mounted, the remaining number, and the quality. It is possible to store various information related to component mounting such as information, rate of holding components by chuck or suction nozzle with respect to the total number of delivered components, and mounting rate to the board, to the detached component supply cassette. Refer to it when mounting the product, and use it to judge that there is a difference between the component catalog data and the component's actual dimensions, so that more appropriate components can be supplied or the mounting conditions are corrected or changed. This is convenient for comprehensive management of components to be mounted and their mounting states, and various actions based on the components to be properly mounted.

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

To use this, batch transfer of parts by the transfer table 15
Since a collective setting of the memories 221 is achieved along with this, it is more convenient than using the conventional component-equipped component supply cassette 14 with a memory. However, it goes without saying that the component supply cassette 14 may be applied to a mounting machine in which the component supply cassette 14 is individually attached and detached.

(Third Embodiment) The third embodiment is shown in FIG.

Can also be mounted on the component supply cassette 14 for use. With this configuration, every time an electronic component is stored in the component supply cassette 14, the storage component information 231 corresponding to the electronic component is attached to the component supply cassette 14 so that the mounting machine or the like can read the component information. You can Moreover, such a detachable type requires only one type of storage component information to be carried in one storage component information, so that a simple component information display format can be adopted and the cost is low. In the third embodiment, the barcode 231
a is a storage component carrier 231b made of a bifurcated spring member
The storage part information 231 is formed by being displayed on the top surface of the. The display of the barcode 231a may be directly printed or a printed sheet may be attached. The storage part information 231 is attached such that the forked part of the carrier 231b sandwiches the upper side of the part feeding part 14a of the part supply cassette 14. The attachment method for attaching and detaching is arbitrary.

FIG. 38B shows storage part information 231 in which a bar code 231a is displayed with a resin case 231c detachably attached to the fixed lever 17a of the part supply cassette 14 as a carrier, and FIG. In addition to exhibiting the same effect as that shown in a), there is an advantage that a special carrier for the storage part information 231 is not necessary.

As shown in FIG. 9, the storage medium carrying the stored component information of each component supply cassette 14 is the optical memory 241 which can be read by infrared communication, and the optical memory 241 of each component supply cassette 14 mounted on the mounting machine is stored. Since the stored contents can be sequentially read by the infrared communication means 242 located at one place, either the infrared communication means 242 or each of the parts supply cassettes 14 can be used to read the stored parts information held by each parts supply cassette 14. Since it does not need to be moved, the reading can be performed in a short time and the production efficiency is improved.

(Fifth Embodiment) The fifth embodiment is shown in FIG.
As shown in (a) and (b) of 0, an example of component management is shown in the case where electronic components are accommodated in the tray 251 and the components are supplied to the mounting machine. 40A shows the tray rack 25.
The tray plate 253 that individually holds the two trays 251 so that they can be taken in and out in multiple stages, and the stored component information of the components accommodated in the tray 251 supported by the tray plate 253 are electrically stored,
Alternatively, a memory 254 that is read and written by the optical reading and writing means 255 and the like is provided. As a result, the information stored in the memory 254 is read and written by the read / write means 2 in order to select the tray 251 for supplying components to the mounting machine.
It is possible to determine whether the tray 251 needs to be read by 55. Further, in the state where the tray rack 252 is mounted on the component supply unit of the mounting machine for component supply, the mounting history of the components accommodated in each tray 251 is the same as that described in the first embodiment. It can be stored in 254 and used for various kinds of management. In FIG. 40B, a memory 261 for storing the information of each electronic component accommodated in each tray 251 accommodated in the tray rack 252 so that it can be collectively read and written, is accommodated in the tray rack 252. Each tray 251
It is possible to manage all the storage parts of all at once.

However, the memory 254 provided in each tray 251 and the memory 261 provided in the tray rack 252 can be used together. This can be similarly applied to the relationship between the component supply cassette 14 and the transfer table 15 described in the first embodiment.
