Abstract

PURPOSE:To allow highly reliable mounting by a method wherein the measurment of the width of a part is done by measuaring both distances from the center of the nozzle of a device to the one end of a part and to the other end, and the deviation is detected from the difference in both distances. CONSTITUTION:To measure the width of a component, the distance X from the center line of the nozzle 6 to the one end of the component 7 and the distance y to the other end is measured to obtain the width l from the sum x+y. The value is abandoned if the value is not of the preset dimension, and if it is of the specified dimension, it is evaluated whether the absolute value of x-y is within a range set beforehand. When the difference of the sensor assignment dimensions x and y is within the set range, the part is mounted on the body to be mounted; if it is not within the set range, it is evaluated that the part is a regular component but not taken out normally, and the device is stopped without mounting it or recovering operation is automatically done by an arbitrary number of times. The device is corrected to the normal position with the relation x=y, and rotated to the specified, arbitrary mounting position with a rotary section 5 to mount the component on the body to be mounted.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a component mounting method using an electronic component mounting machine.

(Prior Art) A conventional component mounting method of this type will be explained with reference to a component mounting machine shown in FIG.

In Fig. 2, 1 is a parts supply section for setting the parts to be mounted, 2 is a head part for taking out the parts from the parts supply part and mounting the parts on the object to be mounted, and 3 is a part for moving the object to the mounting position. The table part, 4 is a detection part that detects the presence or absence of a mounted part, and the thickness and width. 5 is a rotating part that rotates the mounted part in an arbitrary direction, and it moves the mounted part to the mounted position on the table 3 based on a program. At the same time, the specified parts to be mounted are moved to the take-out position by the partial supply section 1 and taken out by the mounting head 2. Detects whether the mounted parts taken out by the mounting head 2 have been taken out correctly, detects the presence or absence of the parts,
The detection unit detects the thickness and width, and attaches it to the object using the specified attachment method. Repeat this according to the program.

(Problems to be Solved by the Invention) In the conventional method described above, it is difficult to detect the mounted component even if the electronic component taken out by the mounting head is shifted from the center.
If the width is good, there is a risk that it will be mounted as it is, and there is a problem that highly reliable component mounting cannot be achieved.

The present invention takes into account the above points and provides a component mounting method that allows highly reliable mounting.

(Means for Solving the Problems) Therefore, the present invention sequentially takes out parts from a parts supply part using a device head, sequentially measures the thickness and width of each taken out part by a detection part, and then makes sure that the measured parts reach a predetermined level. In a component mounting method in which the components are sequentially mounted on the object to be mounted, the width of the component is measured by measuring both distances from the center of the device nozzle to one end and the other end of the component. The presence or absence of deviation of the component from the center of the nozzle is detected based on the presence or absence of a distance difference.

(Function) The width of the part can be measured from the sum of the distance from the center of the installed nozzle to one end of the part and the distance to the other end.

Or, by detecting the presence or absence of deviation from the center of the mounting nozzle based on the presence or absence of a difference between these two distances, even if the width of the part is a predetermined one, if there is deviation, the part will not be mounted on the object to be mounted. By doing so or correcting the bias, highly reliable component mounting can be achieved.

(Example) Examples of the present invention will be described below with reference to FIGS. 1 to 3.

First, the component is taken out from the component supply section by the mounting head 2 (Sl), the presence or absence of the component and the thickness are measured (Sl),
As a result, if there is a part and the thickness of one part is outside the predetermined value, it is discarded (S3), and if the part thickness is the predetermined value, then the width of the part is measured (S4). To measure this width, measure the distance X from the center line of the installed nozzle 6 to one end of the component 7 and the distance y to the other end as shown in Figure 3 (SS)
, the width Q is obtained from the sum x+y. Determine whether the value is the set dimension or not. If it is not the set size, discard it. If it is the set size, check whether the absolute value of x-y is within the preset range. Determine whether or not (
S6). If the difference between the dimensions , determine that it has not been taken out properly, and either stop the machine without installing it, or automatically perform the recovery operation an arbitrary number of times to correct it to the normal position so that x = y (S7) , rotate it in an arbitrary mounting direction specified by the rotation unit 5 (S8), and attach it to the object to be mounted (S9). The above-mentioned center distribution measurement function and center deviation detection function may be added to the detection section of the electronic component mounting machine shown in FIG.

(Effects of the Invention) As described above, according to the present invention, the distances from the center of the installed nozzle to one end and the other end of the component are measured, the width of the component is determined from these distances, and the difference between the two distances is determined. This allows you to know whether there is any deviation from the center of the device nozzle, and even if it is a part of a specified width, if there is deviation, you can either not install it or correct the deviation and install it. , it is possible to perform highly reliable component mounting.
