Description

Flux dipping apparatus with removable disks {FLUX DIPPING APPARATUS HAVING A DISK OF SEPARATION}

The present invention relates to a flux dipping apparatus having a detachable disk, and more particularly, to a flux dipping apparatus having a detachable disk which is coupled to a rotating shaft to facilitate the detachment and fastening of the disk on which the flux is disposed.

In general, the flux dipping apparatus is installed in a component mounter called a "chip mounter" and is applied to a disk to a certain thickness so that the flux can be transferred to a component supplied to the component mounter.

Here, the component mounter is a device for automatically installing a component such as a semiconductor chip at a predetermined position of the printed circuit board. In addition, the component mounter receives various types of components required for the printed circuit board in various ways and mounts them on the printed circuit board by using a suction nozzle operated by a robot.

In this case, if the size of the parts mounted on the printed circuit board is relatively large, the parts are supplied by loading the parts into the tray, but if the parts are relatively small, they are lost or damaged from the position arranged during the transportation or installation work. Often, feeders are used to supply relatively small parts to the component mounter.

The flux dipping apparatus then applies flux to the bumps of the parts to ensure mounting of the supplied parts. For reference, the flux prevents the bumps or areas to be bonded of the part from oxidizing. In addition, the oxide film formed on the surface is removed. When the heat is applied, the bumps are lowered to prevent the adjacent bumps from coming into contact with each other.

Therefore, the flux dipping apparatus is provided with a frame at the bottom, and a disk that is rotated at a constant rotational speed is provided at the top of the frame. And the flux is arranged on the top of the disk. Moreover, the blade which floats at the space | interval of a predetermined clearance gap on the surface of a disk, and has a blade which apply | coats a flux to a fixed height by the clearance is provided.

Therefore, when flux is applied to the surface of the disk at a certain height, the nozzle of the component mounter absorbs the component and contacts the surface of the disk, thereby transferring the flux applied to the disk to the bump of the component.

Here, the disk is coupled to the rotating shaft rotatably coupled to the flame, the rotating shaft is coupled to the drive member of the motor. At this time, the disk is fastened by using a plurality of bolts on the top of the rotating shaft.

However, if the type of flux arranged on the upper part of the disk is changed, or when foreign matter such as dust enters the upper part of the disk, the disk should be washed. However, washing the disc in the state coupled to the rotating shaft does not clean the disk. Therefore, the disk should be removed from the rotating shaft and washed.The bolt should be released to fix it to the rotating shaft. There is a problem that the performance is lowered.

And the locking member 50 is provided with a locking projection 55 to be prevented from being separated in the state coupled to the flange 42 of the rotating shaft 40. Here, the locking protrusion 55 is provided in the shape of a dome or a hook at the end of the stepped portion so that the ball 63 of the ball flanger 60 may be seated and coupled over the curved surface or the inclined surface of the locking protrusion 55.

Hereinafter, the operation of the flux dipping apparatus according to an embodiment of the present invention will be described with reference to FIGS. 5A to 6B. Reference is made here to FIGS. 1 to 4. 6a and 6b is an operating state diagram of the rotating shaft and the disk according to an embodiment of the present invention.

First, the blade 30 is floated on the upper surface of the disk 20 at a predetermined interval so as to have a predetermined clearance. The vertical variable of the blade 30 is variable by the height adjusting member 14, and performs fine adjustment while checking through the measuring member 15.

Thereafter, a predetermined amount of flux F is supplied to and disposed on the upper surface of the disk 20 through the flux supply unit 13.

When the driving signal is applied to the driving member and driven, the disk 20 is rotated by the driving member. At this time, the rotating direction is rotated counterclockwise on the plane.

The flux F disposed thereafter by the rotation of the disk 20 is a gap between the lower end of the blade 30 and the upper surface of the disk 20 in a state of being accommodated in the receiving portion 35 of the blade 30. Through a uniform height is applied to the disk 20 upper surface.

At this time, the flux (F) overflowed to the edge or the center of the disk 20 by the arc-shaped receiving portion 35 provided in the blade 30 is guided to the rotation radius center of the disk 20. And the flux F overflowed to the edge by centrifugal force is guided to the center of the rotation radius of the disk 20 by the side wall 32 provided in the blade 30 again.

Therefore, it is possible to prevent the flux from overflowing the disk 20 by the blade 30 or the centrifugal force. In addition, the cover part 31 provided on the blade 30 prevents the flux from flowing upward.

Thereafter, the type of flux disposed on the disk 20 is changed, or in case of contamination by dust or the like, the blade 30 is first separated.

And the disk 20 is separated from the rotating shaft 40 for cleaning.

At this time, when the disk is rotated in one direction, which is in one direction, the disk 20 rotates in one direction as shown in FIGS. 5A and 6A.

And the locking member 50 coupled to the disk 20 is rotated together with the disk 20, the locking projection 55 formed on the stepped portion 54 of the locking member 50 is the ball of the ball flanger 60 ( 63) to pressurize. When the ball 63 of the ball flanger 60 increases the restoring force of the elastic member 64 and the rotation of the disk 20 is completed by the vertical portion 53, the ball 63 of the ball flanger 60 The restoring force is returned to the original position.

Then, when the disk 20 is raised from the rotary shaft 40, the separation is completed, and when the washing is completed and re-fastened, the insertion protrusion 24 provided at the lower portion of the disk 20 is inserted at the upper portion of the rotary shaft 40. It is seated in the groove 41 and fitted. Therefore, the disk 20 and the rotation shaft 40 are located on the same axis line.

And when the insertion protrusion 24 is rotated in the opposite direction in the state fitted to the insertion groove 41, the disk 20 is rotated in the opposite direction as shown in Figure 5b and 6b.

At this time and the locking member 50 coupled to the disk 20 is rotated together with the disk 20, the locking projection 55 formed on the stepped portion 54 of the locking member 50 is the ball of the ball flanger 60 Press 63. When the ball 63 of the ball flanger 60 increases the restoring force of the elastic member 64 and the rotation of the disk 20 is completed by the vertical portion 53, the ball 63 of the ball flanger 60 It is seated between the vertical portion 54 and the locking projection 55 by the restoring force.

And the blade 30 is combined to perform the initial setting. Therefore, when the type of the flux (F) accommodated in the disk 20, or when contaminated by foreign matter such as dust, the disk 20 itself can be easily separated and washed from the rotating shaft 40.

Although the technical idea of the flux dipping apparatus having the removable disk of the present invention has been described above with the accompanying drawings, this is for illustrative purposes only and is not intended to limit the present invention.

Accordingly, it is a matter of course that various modifications and variations of the present invention are possible without departing from the scope of the present invention. And are included in the technical scope of the present invention.
