Description

Component transfer device of surface mounter

The present invention relates to a component transfer device for a surface mounter, and more particularly, to a component transfer device for a surface mounter that not only makes it possible to stably move a component mounted on a printed circuit board but also shortens the mounting time. .

The recent trend toward miniaturization of electrical and electronic products has led to higher density, miniaturization, and diversification of electronic components. Therefore, Surface Mounting Technology (SMT) is accelerating in the production of printed circuit board (PCB) assemblies. The surface mounting technology is largely classified into the development of a surface mounting device (SMD) and the assembly technology of the surface mounting component. The development of surface-mounted parts is in the trend of miniaturization and integration with the development of semiconductor technology, and the assembly technology is focused on the development of precision assembly equipment and the operation technology of various assembly equipment required for surface mounting of these components. have.

1A and 1B illustrate an example of a surface mounter for mounting the electronic component, and as shown in the drawing, the surface mounters are respectively installed at both sides of the work table 1 forming a reference frame to supply surface mount components. XY table to be moved to the work position is provided is provided with a component supply unit (2) and a component feeder (not shown) to be installed therein, the X-axis frame (3a) and Y-axis frame (3b) ( 3), a conveyor 4 mounted on the work table 1 for conveying a work printed circuit board P, and a surface mount component mounted on the XY table 3 and supplied by a component feeder. And a head portion 5 mounted on the printed circuit board P.

As described above, the surface mounter includes a component supply unit in which the head part 5 is supplied by the XY table 3 when the printed circuit board P on which the surface mount component is mounted is transferred to the work space by the conveyor 4. (2) and the component feeder is sucked to the component and the head portion 5 which sucks the component is moved to the mounting position of the printed circuit board P by the XY table 3 to mount the component.

The part transfer structure, which allows position transfer so that the head part 5 sucks a part from the part supply part and mounts it on the printed circuit board P, has a Y-axis frame 3b on both sides of the work table 1. These are respectively provided, one side of the Y-axis frame (3b) is coupled to the first ball screw (6) and the servo motor 7 for driving it, one X-axis table across the Y-axis frame (3b) (3a) is coupled and one side of the X-axis frame (3a) is coupled to the first ball screw 6 of the Y-axis frame (3b) by the operation of the servomotor 7 and the first ball screw (6). It moves along the Y-axis frame 3b. The second ball screw 8 and the servomotor 9 for driving the same are coupled to the X axis frame 3a, and are connected to the second ball screw 8 to provide a head to the X axis frame 3a. The unit 5 is coupled so that the head unit 5 moves along the X axis frame 3a by the operation of the servomotor 9 and the second ball screw 8. This structure is such that the parts are supplied or mounted at the mounting position by moving the XY Cartesian coordinate system formed by the X-axis frame 3a and Y-axis frame 3b of the XY table 3 by the head portion 5. The movement of the head part 5 becomes possible.

However, in the conventional structure as described above, the conveying system for absorbing the supplied components and moving the components to the mounting position to transfer the mounted components is one side of the drive unit for driving the X-axis frame 3a and the head portion 5. Because it is installed only in the vibration is generated when driving, and this vibration is suppressed, the mounting efficiency has to be reduced by having to absorb and install the parts. On the other hand, if both sides of the drive unit is installed rather than one side, the same drive unit is additionally installed, not only increases the manufacturing cost but also has the disadvantage that the structure becomes large.

Accordingly, an object of the present invention is to provide a component transfer device for a surface mounter that can stably move a component mounted on a printed circuit board and shorten the mounting time.
