Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to, for example, the assembly of leadless electronic components when attaching minute leadless electronic components to an electronic circuit board, or the positioning of electronic components used in a taping apparatus in general. It is about the method.

Conventional technology Conventionally, leadless electronic components (hereinafter referred to as components) that have been sucked into a suction nozzle are moved to a predetermined regulation location, and are regulated in two orthogonal directions using two pairs of claws, and the components are sequentially mounted. The method used is to transport the materials to different locations. In the feeding direction, the parts are generally rectangular in shape, and the common method is to unify the long sides of the parts and sequentially separate and feed the taped parts using a suction nozzle. At this time, the method of regulating the component is to have regulating claws wait at positions of equal dimensions toward the center of the component, or to have regulating claws in the long side direction of the component wait at a position closer to the component. Therefore, the method is to first regulate the short side surfaces of the parts using the two pairs of regulating claws.

Alternatively, even if one direction is regulated first, if the longitudinal direction is reversed in the taped state, the short side surface will be regulated first.

Problems to be Solved by the Invention As described above, if the longitudinal direction of the component is adjusted first, as shown in FIG. When the short side ratio is wide, there is a drawback that if there is an inclination of about 30 degrees, the direction of the part must be rotated 900 times.

In view of the above-mentioned problems, the present invention proposes a method for more accurately correcting the position of parts regardless of the direction in which the parts are supplied, even when the suction posture of the parts is relatively unstable.

Means for Solving the Problems In order to solve the above-mentioned problems, the method for adjusting the position of parts according to the present invention provides a method for adjusting the position of a rectangular part when the part sucked by a suction nozzle is adjusted from two directions perpendicular to each other. The direction of the long side is first regulated from both sides, and the direction of the short side is secondly regulated.

Function: With the above-described configuration, the present invention can be used when the state of suctioning parts is unstable, for example, when the long side/short side ratio of the previous example is 60.
Even if there is an inclination of about 100 degrees, the position can be adjusted in the normal direction.

Embodiment Hereinafter, an IJ'-dos I/S electronic component mounting apparatus to which a leadless electronic component position adjustment method according to an embodiment of the present invention is applied will be described with reference to the drawings.

FIG. 1 shows the configuration of a glue-less electronic component mounting apparatus according to an embodiment of the present invention.

The printed circuit board 1 is held in advance on an XY table 2 that can be moved to any position in the X-Y directions, and the components 3 are set in a cassette 4 that sequentially supplies components 3 that have been taped in advance with uniform long sides. The suction nozzle 6 holds the parts 3 from the 02 table 5 arranged on the Z table 5, which can be moved to any position in the Z direction, at the suction position A, and by specifying this in advance, the suction nozzle 6 is rotated. The printed circuit board is selectively rotated at position B and moved to a predetermined position adjustment position CK using a means provided separately (-1 position adjustment is performed in two directions, the mounting direction is rotated at D station, and the printed circuit board is moved to a predetermined position adjustment position CK). The process is structured such that the installation is carried out on the top of 1.

As shown in FIG. 2, at the position adjustment position BK, two pairs of claws 7 are waiting in two directions orthogonal to each other, and when the nozzle 6 moves the part 3, it moves toward the center of the part. Start by adjusting the position of the parts. At this time, the claw 7b that regulates the long side surface of the component from both sides starts to move first, and after regulating the component 3, the claw 7a that regulates the short side surface from both sides moves second. By adopting this feature, the inclination of the suction posture can be more reliably adjusted in the normal direction.

Effects of the Invention As described above, the present invention, when correcting a part sucked by a suction nozzle from two directions perpendicular to each other, always adjusts rectangular parts by selectively rotating the suction nozzle before the correction. It is possible to use a method of adjusting the long sides first and the short sides second, and it is possible to more accurately adjust the inclination in the attracted state in the normal direction.
