In this case, the logical product of the logical product of the small requirements of the logical product group and the logical sum of the small requirements of the logical product group is interpreted as the process condition.

According to the sixth aspect, the data structure is simplified, and the process distribution process by the processor is further facilitated. In the seventh aspect of the first invention, when a plurality of devices that impose conditions on component mounting are arranged on a component mounting line, the above process conditions are set for each device, and i = 1 to v, w is a natural number. The process conditions of this component mounting line are substantially as follows: process condition = (large requirement 1) * (large requirement 2) *... * (Large requirement v) large requirement i = (condition of process i1) + (process i2) (Condition) + ... + (process iw condition) is given to the processor.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. [First Embodiment] FIG. 1 shows a schematic configuration of a component mounting process design support apparatus according to one embodiment of the present invention. This device is a general computer system in which a console (12), an external storage device, and a printer are connected to a processor (computer) 10. The console 12 includes a display device such as a CRT and input devices such as a keyboard and a mouse. In the figure, a design information file 14, a used component identification information file 16, a component information file 18, a process distribution table file 20, and an output file 22 are digitized information stored in an external storage device such as a hard disk. 24, the arranged parts list 26 and the costing table 28 are output information by the printer.

FIG. 2 shows a procedure for setting up a component mounting process by the apparatus shown in FIG. Hereinafter, the numerical values in parentheses indicate the step identification numbers in FIG. (50) The identification information of the electronic component to be mounted on one wiring board is extracted from the design information file 14 created by the design unit, and the used component identification information file 16 is created.
This extraction is performed by the processor 10 or a device (not shown). The used component identification information file 16 includes, for example, a circuit identification symbol in a design drawing, a symbol (model of a component) stamped on a package of a component, and the like.

(52) On the other hand, in the component information file 18, component identification information and component mounting conditions are stored in association with various components, and additional information such as presence / absence of component stock, delivery date and unit price is stored. Have been. This additional information is information from the material departments of the company and other companies, and is frequently updated. However, the component identification information and the component mounting conditions are stored in a library. The processor 10 searches the component information file 18 using the component identification information from the used component identification information file 16 as a keyword, and acquires the component information. If there is no corresponding component information in the component information file 18, the component identification information is displayed on the screen of the console 12.

(54) The processor 10 reads the process distribution table file 20 and determines, for each component read from the component information file 18 in step 52, which process of the process distribution table includes the component information. By doing so, the parts are distributed to the process. FIG. 3 shows an example of a simplified process distribution table.

Step 1 corresponds to part or all of one automatic mounting line. The mounting conditions in step 1 are the conditions required for the electronic components by the inserter, soldering device, cleaning device, and the like installed on this line.
Form is DIP, part size is length L11-L12, width W
11 to W12, heights H11 to H12, number of pins in the range N11 to N12, heat resistance rank A or higher, cleaning resistance, and mounting surface on the wiring board table (number of components to be mounted) Is the condition). When all these requirements are satisfied, the electronic component is sorted to Step 1.

In general, this process condition is expressed by * for a logical product and + for a logical sum. If u and k are natural numbers and i = 1 to u, process condition = (requirement 1) * (requirement 2) * (Requirement 3) * ... * (Requirement u) Requirement i = (Small requirement i1) + (Small requirement i2) + ... + (Small requirement ik) (1) If k = 1, the minor requirement is equal to the requirement. For example, when a component mounting apparatus for a component of the form A and a component mounting apparatus for a component of the form B are arranged in series on one automatic mounting line, it suffices to satisfy one of the requirements required by both apparatuses. Is the logical sum of Also, even when one component mounting apparatus is arranged on one automatic mounting line, if the component mounting apparatus is for components of the form a and the form b, the logical sum of the small requirements is obtained.

Steps 2 to 4 are the same as step 1 described above. In FIG. 3, the hatched portion indicates that there is no limit. Step 2 is an automatic mounting step using an onserter, and steps 3 and 4 are manual mounting steps including manual operations. First, it is determined whether or not the condition of the automatic mounting process 1 or 2 is satisfied. If not, it is determined whether or not the condition of another manual mounting process is satisfied.

The process distribution table file 20 of FIG. 1 also stores unit man-hours and process unit prices for each process, and serial / parallel information between processes as additional information. The unit man-hour is the man-hour per component in the process, and the process unit price is the mounting unit price per component determined in consideration of cost amortization cost, personnel cost, etc. of the equipment used in the process. is there. In addition, the inter-process serial / parallel information is, for example, information that process 1 and process 3 in FIG. 3 are executed in parallel on different lines, and process 1 and process 2 are sequentially executed in one serial line. It is.

(56) The number of steps in each step is calculated from the number of parts allocated to each step and the unit man-hour, and a process table is created based on the number of steps and the serial / parallel information between steps. (58) A parts list for each process is created based on the parts sorted in step 54. Step 52
If there is no inventory information included in the component information read out in step 2, the component identification information and the delivery date are extracted, and an ordered component list is created.

(60) The cost of the mounting board is calculated on the basis of the above-described component unit price, process unit price, and the number of components allocated to each process. (62, 64) The results obtained in steps 56, 58, and 60 are converted into the process chart 24, the parts list 26, and the cost calculation table 28.
, And also as the electronic file 22.

(66) A person evaluates the output process chart or the like, and if it is judged that the output is not appropriate, the console 12 is operated to change the process distribution table file 20 and the process returns to the step 54. By the above-described processing, the component mounting process design is performed automatically or semi-automatically, quickly and appropriately. In addition, the only manual work required to perform this processing is to create the component information file 18 and the process distribution table file 20.
The above additional information in the component information file 18 is obtained from the material department, and if other component information and process distribution tables are generally created, they can be used many times in common for various types of mounting boards. It's easy.

[Second Embodiment] In the present invention, the degree of difficulty in the process allocation process and the process allocation table changing process in steps 54 and 66 varies depending on how the process allocation table is created. The change process changes the combination of devices to be placed on the line, so to make the change process easier,
It is preferable to divide the process for each device in the line and to provide combination information of the process (serial / parallel information between processes).

Assuming that a record (part information record) of the part information file 18 is represented by items 1 to n, item 1
In addition to the items related to the process allocation table such as the component form, the number of pins, the component height, the heat resistance rank, etc., those not related to the process allocation table such as necessity of arrangement, function abbreviations, comments, etc. Also exists. However, in order to facilitate the process distribution process, it is preferable to make the data structure of the process distribution table 20 similar to the records of the component information file 18.

Therefore, the component information record is associated with the condition of step i corresponding to one device as follows. Part information record = item 1: item 2: item 3:...: Item n process i condition = DIP * # * A *... ## where # means irrelevant. It is also assumed that item 1 is a major component type, DIP is an element of item 1, item 2 is a small component type, item 3 is a heat resistant rank, and A is an element of item 3. In this case, the process i condition means that the component form is DIP and the heat resistance rank is A.

The reason why the part form is different between the large classification and the small classification is that the condition of the process i is expressed as short as possible.
This is to simplify the setting work. For example, DIP
Is a set of elements a to q, it is assumed that device i can handle any DIP but device j can handle only a. Is expressed by a simple conditional expression. But,
If no major classification item is provided, a, b,..., P or q must be designated to designate DIP. If no minor classification item is provided, The designation itself becomes impossible.

Since the process i conditions need to be manually input, text format data is preferable in the input stage. However, in the process distribution operation stage, the data is converted to a binary format in order to increase the processing speed. Are preferred. In order to simplify the distribution process, it is preferable to simplify the data format of the process conditions. Therefore, for example, if the part form is
a, b, or c (heat resistance is hereinafter referred to as A rank).

Step i conditions = # * a * A *... * # + # * B * A *... * # + # * C * A *. However, all the parts forms of the small classification are a, b, c,.
.., p, q, where a, b, c,..., O, or p is a condition, the conditional expression becomes longer. Therefore,
An attribute is added to the conditional expression and expressed as follows.

Process i condition = # * q * A *... ##: 0 1 0... 0 Here, 1 indicates that the corresponding item is other than that (complementary set)
And 0 means the corresponding item itself. The bit corresponding to # is irrelevant. The step i condition in the above equation means that the component form is a to q other than q (a to p) and the heat resistance rank is A. Since the attribute data may be one bit per item, one word is usually sufficient.

Assuming that the above two lines are expressed in one line, if the part form is p or q, the process i condition = (# * p * A * ... * #: 000 ... 0) + (# * Q * A * ... * #: 000 ... 0) (2) When the component form is other than p and other than q, the process i condition = (# * p * A * ... * #: 010 ... 0) * (# * q * A * ... * #: 010 ... 0) (3)

Here, in order to facilitate the setting of the attribute, it is preferable to set the attribute to bits of only 0 or 1 as much as possible. If the above expression (2) is expressed as a logical product as in (3), the expression becomes longer, and if the above expression (3) is expressed as a logical sum as in (2), the expression becomes similarly longer. do not do. The reason for the lengthening is that "p or q"
"Other than a, other than b, other than c, other than d, other than e, other than f,
Other than g, other than h, other than i, other than j, other than k, other than l, m
, Other than n and other than o ", and" other than p and other than q "means" a, b, c, d, e, f, g,
h, i, j, k, l, m, n or o ".

Therefore, in the case of the logical product expression, the meanings of bit 1 and bit 0 of the attribute are reversed from those of the logical product expression. In this case, in most cases, the attribute bits are all set to 0, so that the attribute setting work becomes an exceptional work and almost disappears, and the addition of the attribute shortens the conditional expression, thereby setting and changing the conditional expression. Work becomes easier. According to this rule, the above equation (3) can be expressed as follows: Process i condition = (# * p * A * ... * #: 000 ... 0) * (# * q * A * ... * #: 000... 0) (4).

In the above equation (4), the process i condition = (small requirement 1)
In general, the process i condition can be simply expressed as * (small requirement 2): process i condition = {(small requirement 11) * (small requirement 12) *... * (Small requirement 1r)} * ｛(small requirement) Requirement 21) + (Small requirement 22) + ... + (Small requirement 2s1)｝ * {(Small requirement 31) + (Small requirement 32) + ... + (Small requirement 3s2)} * * (Small requirement t1) + (small requirement t2) + ... + (small requirement tsu) (5) Can be represented. In data storage, simply the first AND group, the second OR group, the (t-1) th OR group (small requirement 11) (small requirement 21) ... (small requirement t1) (small requirement 12) (Small requirement 22) ··· (Small requirement t2) ··········· (Small requirement 1r) (Small requirement 2s1) ··· (Small requirement tsu) What is necessary is just to divide and divide into a logical product group and one or more logical sum groups. This simplifies the data structure. If it is promised that logical AND will be performed between the groups, it has the same meaning as the above equation (5).

The above process conditions are manually input for all devices that can be used for the component mounting line. Here, if requirement j = (small requirement j1) + (small requirement j2) +... + (Small requirement jk), the above equation (5) can be simply expressed as: process i condition = (requirement 1) * ( Requirement 2) * (Requirement 3) *... * (Requirement u) and have the same form as the above equation (1). When k = 1,
Requirement = small requirement.

Next, when there are w devices that impose conditions on component mounting in one component mounting line, the process conditions of this line are simple, and the logic of the above process i condition of each device is simple. Product, process condition = (process 1 condition) * (process 2 condition) *... * (Process w condition).

When a component mounting device for a component of type i and a component mounting device for a component of type j are arranged in series on one component mounting line, any one of the requirements required by both devices may be satisfied. In this case, the process condition includes a logical sum {(process i condition) + (process j condition)}. Therefore, in general, the process conditions of the mounting line are as follows:
When i = 1 to v and w are natural numbers, process condition = (major requirement 1) * (major requirement 2) *... * (major requirement v) major requirement i = (condition of process i1) + (process i2) +) + (Step iw condition). In other words, the process condition of the mounting line and the process condition of the device at the lower level are expressed in the same format.

When there are a plurality of component mounting lines in one factory, if the components are disassembled into a series of serial process units, all the combined lines are expressed in the same manner as in the above equation.
Next, for one mounting line, for example, when the second device is (process 2 condition), replacing the second device is
This corresponds to replacing (step 2 conditions). Although many combinations are conceivable in this way, since the computer is good at it, man-hours can be calculated for all possible combinations to obtain the minimum man-hour of this mounting line. Similarly, a minimum number of man-hours can be obtained for a plurality of component mounting lines as a whole.

In this embodiment, the data structure of the process distribution table 20 is similar to the record of the component information file 18 and the data length of the process condition is as short as possible. It is possible to obtain a solution with the minimum number of man-hours (optimal solution) in time. The present invention also includes various modified examples. For example, a plurality of process distribution tables are created, and all or all of the process distribution tables selected through the console 12 are stored in step 54 in FIG.
The following processing may be performed. Further, the present invention is also applicable to a modification for cutting a wiring pattern, adding / deleting wiring, and adding / removing components to / from a mounting board.

Can be performed in a short time, and the identification information of the electronic components to be mounted on the wiring board can be obtained from the design information. Although the component reference and the distribution reference are created in general, if the component information and the distribution reference are created, they can be used many times in common for various types of mounting boards, so that there is an excellent effect that the manual operation is simplified.

According to the second aspect of the present invention, the description of the small requirements is unified, so that the manual work for setting the process conditions and the process distribution process by the processor are easy, and the process conditions can be easily changed.
