Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component mounting method and apparatus used for mounting various components on a circuit board, for example.

[0002]

2. Description of the Related Art Several methods have been conventionally used to mount various electronic components on a circuit board. In any case, the mounting of electronic components is completed by mounting the electronic components at the prescribed positions on the conductor land made of copper or the like on the circuit board and then fixing the mounted electronic components by soldering or curing the adhesive. To do.

Conventionally, mounting of electronic components and fixing of mounted electronic components are performed by different dedicated working machines.

The component mounting machine is capable of sequentially mounting various kinds of electronic components, which are successively carried by suction nozzles or the like, at a plurality of predetermined positions on one substrate to be supplied. This is often accompanied by movement of the substrate, which means moving in the XY2 directions that are orthogonal to each other. However, the parts to be installed are not yet fixed. Therefore, every time the board is moved, the inertia according to the mass of this electronic component works on the electronic parts mounted on the board at the beginning and at the time of the stop, and the electronic parts mounted on the board are mounted first. This may cause a positional shift of the electronic components being used. Therefore, the movement of the substrate has a speed limit according to the mass and height of the electronic component previously mounted.

Therefore, conventionally, in order to increase both the mounting efficiency of electronic components and the yield rate of circuit boards as much as possible, mounting is started from electronic components with small mass to those with large mass, and the moving speed of the substrate is increased. Is designed to decrease as the mass of electronic components increases. As a result, it is possible to always mount the electronic component at the maximum substrate moving speed corresponding to the electronic component, and prevent the electronic component previously mounted from being displaced due to the movement of the substrate.
The operation control of the component mounting machine for such component mounting is
It is performed using tact data that sets the speed of the operation cycle.

[0006]

By the way, in recent years, the number and types of electronic components mounted on one substrate are increasing. To cope with this, various components are shared and mounted by sequentially using a plurality of component mounting machines sequentially arranged from the upstream side to the downstream side of the substrate transfer line.

In this case, the electronic components mounted by the component mounting machine used later may include an electronic component having a smaller mass than the electronic component mounted by the component mounting machine used previously.

In order to uniformly mount various components in each component mounting machine by the operation control based on the tact data set according to the above-mentioned conventional concept, the component mounting machine used previously is used. When mounting an electronic component smaller than the electronic component, the board is moved at a high speed corresponding to the electronic component with a small mass, and the electronic component with a large mass mounted by the component mounting machine used earlier is displaced. Will occur.

An object of the present invention is to solve such a problem, and while using the tact data which is conventionally set in each component mounting machine, the components to be mounted by the component mounting machine to be used later are first An object of the present invention is to provide a component mounting method and a device for mounting the component mounting machine so that even if the component has a smaller mass than the mounted component, the component mounting method and the component mounting apparatus can be mounted easily without any problem. .

The held one is moved to a position for picking up by the suction nozzle 3a. When the parts supply cassette 11 becomes empty, this is confirmed by a notification based on automatic detection or a finding by the operator himself, and is replaced manually.

Of course, the present invention is not limited to the above-described component supply system.

The component mounting apparatus A of this embodiment does not exceed the movement limit speed of the substrate 1 corresponding to the type of the electronic component 6 previously mounted, and the substrate 1 suitable for the type of the electronic component 6 to be mounted next. The plurality of component mounting machines a that sequentially mount various electronic components 6 based on the tact data set so as to obtain the moving speed of Store some tact data,
When the electronic component 6 is mounted by the component mounting machine a used later, the tact data set for the component mounting machine a used later is compared with the stored tact data, and the component mounting machine a used later is compared. When the movement limit speed of the board 1 corresponding to the electronic component 6 to be mounted by exceeds the movement limit speed of the board 1 in the component mounting machine a used previously, component mounting to be used later so as not to exceed this The component mounting method is used in which the tact data for the machine a is corrected, and various electronic components 6 are mounted by the component mounting machine a to be used later based on the corrected tact data.

According to this, the movement speed of the substrate 1 suitable for the type of the electronic component 6 to be mounted next can be obtained without exceeding the movement limit speed of the substrate 1 corresponding to the type of the electronic component 6 mounted first. A plurality of component mounting machines a for mounting various electronic components 6 based on the tact data set as described above are sequentially used to mount the various electronic components 6 on one substrate 1 in advance. The tact data set for the component mounting machine a is stored, and the tact data set for the component mounting machine a to be used later is compared with the stored tact data, and the component mounting machine a to be used later is stored. When the movement limit speed of the board 1 corresponding to the electronic component 6 to be mounted by exceeds the movement limit speed of the board 1 in the component mounting machine a used previously, component mounting to be used later so as not to exceed this Set for machine a Since the tact data is corrected, the tact data according to the type of the electronic component 6 to be mounted by each component mounting machine a is set to improve the efficiency of the component mounting work and move the substrate 1 as before. The tact data set as usual in the component mounting machine a to be used later is minimized in units of the component mounting machine a to be used next, while preventing misalignment of the electronic component 6 mounted in With a simple tact data change operation, it is possible to make it appropriate in consideration of the type of the electronic component 6 mounted by the component mounting machine a used previously, and to use it later based on this corrected tact data. The mounting of various electronic components 6 by the component mounting machine a can be prevented from adversely affecting the electronic components 6 of any type mounted by the previously used component mounting machine a. it can.

Therefore, in terms of work efficiency in each component mounting machine a, while using the tact data set in the conventional manner, the component mounting machine a previously used for the electronic component 6 to be mounted by the component mounting machine a to be used later is used. Even if there is an electronic component 6 having a smaller mass than the electronic component 6 mounted in step 3, the electronic component 6 can be easily mounted without any problem and a defective product can be prevented.

It should be noted that the correction of the tact data in the component mounting machine a used later is limited to the movement of the board 1 only for the electronic component 6 which exceeds the movement limit speed of the substrate 1 in the component mounting machine a used earlier. It is preferable to carry out so as to be equal to the speed.

In this way, the minimum correction is made only within the range in which the electronic component 6 mounted by the previously used component mounting machine a is adversely affected, and the electronic component 6 mounted by the later-described component mounting machine a is mounted. Among them, the electronic component 6 whose movement speed of the substrate 1 is limited by the electronic component 6 mounted by the component mounting machine a used previously can be minimized, and unnecessary correction and time extension are eliminated.

For these reasons, the component mounting apparatus A of this embodiment
As shown in FIG. 5, the moving speed of the substrate 1 suitable for the type of the electronic component 6 to be mounted next does not exceed the moving limit speed of the substrate 1 corresponding to the type of the electronic component 6 mounted first. It has a plurality of component mounting machines a combined with a control means D for controlling to mount various electronic components 6 based on the tact data set so as to be obtained, and the component mounting by the component mounting machine a used first. The storage unit E for storing the tact data applied by the control unit D, the tact data set corresponding to various electronic components 6 to be sequentially mounted on the component mounting machine a to be used later, and the stored tact. Comparing with the data, the movement limit speed of the board 1 corresponding to the electronic component 6 to be mounted by the component mounting machine a used later is compared with the movement limit speed of the board 1 in the component mounting machine a used earlier. Determine whether to exceed Based on the determination means F and the determination that the determination means F is exceeded, the tact data of the component mounting machine a to be used later is calculated based on the movement limit speed of the board 1 in the component mounting machine a to be used first. Used component mounting machine a
There is provided a correction means G for making a correction so as not to exceed the movement limit speed of the board 1 and a notification means H for notifying the component mounting machine a to be used later that tact data has been changed.

As a result, when each of the plurality of component mounting machines a sequentially mounts the various electronic components 6 under the control of the operation of the control means D, the previously mounted electronic components 6 are mounted.
Do not exceed the movement limit speed of the substrate 1 corresponding to the type of
Using the tact data set so that the moving speed of the substrate 1 suitable for the type of the electronic component 6 to be mounted next is obtained, the various electronic components 6 are mounted efficiently and previously by the movement of the substrate 1. 6 can be mounted without a problem such as a positional deviation, and the tact data used by the control means D for the previously used component mounting machine a is stored in the storage means E and used later. A board corresponding to the type of the electronic component 6 mounted by the previously used component mounting machine a in comparison with the stored tact data, the tact data being set corresponding to the various electronic components 6 sequentially mounted Since the discriminating means F discriminates whether or not the movement limit speed of 1 is exceeded, all kinds of electronic components 6 to be mounted,
For all component mounting machines a that perform this mounting, the tact data themselves of the two component mounting machines a used before and after are not mounted, without performing comprehensive planning, judgment, setting, and management. It is possible to know the influence of the type of the electronic component 6 that is used by a simple device or control.

In this case, the discrimination means needs to detect the tact data set for each component mounting machine a and the tact data applied to the component mounting by the control means D of the previously used component mounting machine a. is there. In this embodiment, each of the storage means E, the correction means G, and the notification means H uses the internal function of the control means D peculiar to each component mounting machine a, and the discriminating means F controls each of the control means. By communicating with D,
The detection and the discrimination can be performed. However,
When the control means D of the component mounting machine a used before and after are set in a state in which they can communicate with each other, the discrimination means F can also use the internal function of the control means D. It is easy to configure the control means D and the discrimination means F with a microcomputer.

The detection is a control means D according to the type of information.
It is possible to freely perform writing to the internal memory such as the above and various external recording media, and reading and writing means of writing contents according to these.

The storage means E in this embodiment is provided on the substrate 1 as shown in FIG. 6, or is a substrate supporting member for supporting the substrate 1 and mounting it on the electronic component 6 as shown in FIG. If there is 21, a storage member e1 that is provided on the substrate support member 21 to store and read the given tact data, and the component mounting machine a are used in advance to mount the electronic component 6 When performing, the tact data set by the component mounting machine a is stored in the storage member e1 and the writing means e2 as shown in FIG. 8 is provided.

According to this, since the judgment of the tact data and the management of the correction can be given to the board 1 itself on which the electronic component 6 is mounted, it is not necessary to set the kind of the board 1 or check the board 1. Both operation and control can be simplified, and erroneous operation due to incorrect setting or collation can be avoided.

As the information of the tact data, it is possible to handle the information itself, but it is also possible to store it as a symbol so that it can be stored and read. The storage member e1 is a non-contact type magneto-optical recording medium or electronic recording. Various conventionally known external recording media such as a medium and a magnetic recording medium can be adopted, and the writing means e2 and the reading means f can be used.
The number 1 may be adapted to this.

When it is determined by the determination means F that the movement limit speed of the board 1 in the previously used component mounting machine a is exceeded, the correction means G operates accordingly and is used later. The tact data for the component mounting machine a to be used later is corrected so that the movement limit speed of the substrate 1 in the component mounting machine a does not exceed the movement limit speed of the substrate 1 in the component mounting apparatus a used first. Therefore, appropriate tact data is automatically set again for the component mounting machine a to be used later,
Even if the electronic component 6 is mounted without any troubles by manual operation and the tact data needs to be corrected, the labor is not necessary and the high-speed processing can be performed to prevent the generation of defective products due to erroneous operation.

Moreover, in this embodiment, the notifying means H simultaneously operates together with the correcting means G, and the component mounting machine a to be used later is used.
Since the correction of the tact data is notified to the worker, the operator has a smaller mass in the electronic component 6 to be mounted by the subsequently used component mounting machine a than the electronic component 6 mounted by the previously used component mounting machine a. This is convenient because it is possible to realize that the tact data has been corrected to cope with this. FIG. 9 shows a flowchart of the component mounting work by such an operation.

However, the tact data is not corrected by notifying the tact data by the notifying means H without providing the correcting means G so that the operator can surely correct the tact data as needed. Therefore, it is possible to prevent the occurrence of defective products.

As in this embodiment, the control means D, the writing means e2 of the storage means E, the correction means G, and the notification means H are provided.
However, by providing each of the plurality of component mounting machines a used before and after, it is possible to make them simple with a very small amount of information to be handled, and the discriminating means F is also provided for each component mounting machine a. The same thing can be said about this when it is provided in the above. However, these are provided with a control means such as a microcomputer which is a superordinate of each component mounting machine a like the determination means F of the present embodiment, and the internal function of this is used. According to this, it is possible to manage and correct the tact data by using one upper control means.
