Description

Surface treatment device {APPARATUS FOR TREATING SURFACE}

The present invention relates to a surface treatment apparatus for treating the surface of parts by painting or plating, as a surface treatment apparatus.

Fasteners used in industries such as automobiles, ship parts, and building materials are subjected to various surface treatments such as painting or plating for the purpose of corrosion, appearance improvement, and performance improvement. have corrosion resistance.

In order to surface-treat such parts such as fasteners, the basket containing the parts is immersed in the surface treatment agent contained in the surface treatment tank for a certain period of time.

Then, by raising the basket to the upper side of the surface treatment tank and fixing it on the rotating jig and then rotating the rotating jig, the surface treatment agent accumulated in the groove formed in the part is released or the surface treatment agent coated unevenly on the outer surface of the part is removed will do

However, there is a problem in that it is difficult to escape the surface treatment agent accumulated in the grooves of the parts in the above-described surface treatment process.

For example, grooves such as 'U', '+', '-', and threads are formed in bolts and nuts, which are one type of fastener. The remaining surface treatment agent is removed by rotation of the jig.

At this time, the fastener is biased toward the inner circumferential surface of the basket by centrifugal force, and the surface treatment agent escapes as the surface treatment agent escapes from the groove of the fastener arranged to face the inner circumferential surface of the basket, but the groove of the fastener arranged to face the center of the basket or another direction In this case, the surface treatment agent does not escape.

And when the groove of the part immersed in the surface treatment agent faces downward, air pockets are generated and the surface treatment agent cannot be applied deep inside the groove, resulting in surface treatment defects.

Therefore, in the surface treatment process, the surface treatment agent accumulated in the groove of the fastener cannot be completely escaped, and since the surface treatment agent is not completely applied deep into the groove of the part during immersion, the surface treatment is not performed with a uniform thickness on the surface of the part. There is a problem that it does not.

Furthermore, when the surface treatment agent accumulated in the grooves of the fastener that has not been completely escaped is dried while the surface treatment agent remains as it is, the fastener cannot be fastened, and the surface treatment agent accumulated in the grooves of the fastener is applied to the surface of other fasteners as it flows. There is a problem that agglomeration occurs or leads to defects due to reduced precision.

In addition, the internal structure of the mesh basket 400 When the lower surface (400a) has an inclined structure that increases toward the center side, the parts are moved in the upward inclined direction, so that the agitation of the parts is made more effectively.

Accordingly, in the present invention, when the mesh basket 400 revolves, rotates, and fluctuates up and down, in the process of moving parts in the lateral and vertical directions, the mesh basket 400 rides the lower surface 400a and tilts the center upward. By making irregular movement in several directions including direction, the surface treatment capacity can be further increased as the stirring action of the parts is made more active.

On the other hand, the mesh basket 400 may be configured to rotate together with the surface treatment parts caught during rotation.

In the surface treatment process, in the process of rotating the mesh basket 400 such as revolution and rotation, the parts accommodated therein move, and the parts slide along the inner circumferential surface of the mesh basket 400 in the direction of centrifugal force in the mesh basket 400 Tendency to stay in position.

That is, the parts do not rotate together by revolution or rotation of the mesh basket 400, but have a tendency to stay at the outermost position in the centrifugal force direction inside the mesh basket 400 by centrifugal force.

Due to this tendency, when the mesh basket 400 is immersed in the surface treatment agent of the surface treatment container V and rotates, it is difficult to introduce the surface treatment agent into the groove formed on the surface located on the centrifugal force direction side of the part, and vice versa. When the mesh basket 400 rotates away from the surface treatment container V, it is difficult to escape of the surface treatment agent in the groove formed on the surface located on the side opposite to the centrifugal force in the part.

Accordingly, in the present invention, when the mesh basket 400 rotates, the protrusions 410 disposed in the longitudinal direction may be formed on the inner surface of the mesh basket 400 so that parts accommodated therein are caught and rotated together.

In this case, a plurality of the protrusions 410 may be spaced apart from each other along the inner circumferential surface of the mesh basket 400 .

When the mesh basket 400 rotates during revolution or rotation by the protrusion 410 formed in this way, the parts accommodated therein are caught and rotated together, so that the surface treatment of the parts is uniformly made, quality can be improved.

As a result, in the surface treatment device according to the present invention, the swing driving unit 500 is configured to swing the mesh basket 400 up and down together with the orbital driving unit 200 and the rotation driving unit 300, thereby In addition to the lateral stirring of the parts, which is mainly caused by the above, the vertical stirring is also smoothly performed, so that the surface treatment capability of the parts can be increased and the surface treatment quality can be improved.

In addition, according to the present invention, the inner lower surface 400a of the mesh basket 400 adopts an inclined structure that increases toward the center, so that the parts are moved in the upper inclined direction during revolution, rotation, and vertical movement, so that the agitation of the parts is made more effective. can

And, the present invention is a locking configuration so that the parts are caught and rotated together when the mesh basket 400 is rotated, and a protrusion 410 disposed along the longitudinal direction on the inner surface of the mesh basket 400 is configured, so that the mesh basket 400 is provided. As the parts accommodated therein are caught and rotated during rotation during revolution or rotation, the surface treatment of the parts is made uniformly, so that the quality of the surface treatment of the parts can be improved.

Furthermore, in the present invention, a rotation driving motor 321 for controlling the rotation of the mesh basket 400 is configured, so that the rotation of the mesh basket 400 is not constantly maintained while the rotation is made, but a change to the rotation can be given. As there is, that is, it is possible to generate a change in the rotation speed and rotation direction of the mesh basket 400, and implement a rotation movement of an irregular speed and direction rather than a rotation movement of a constant speed and direction, and agitation of the parts By doing this better, it is possible to increase the surface treatment capability of the part.

In addition, according to the present invention, due to the effective stirring action of the parts as described above, it is possible to reliably remove the non-uniformly coated surface treating agent together with the escape of the surface treating agent accumulated in the grooves of the parts.

On the other hand, in the present invention, the gripper 350 for gripping the upper portion of the mesh basket 400 is configured, so that the cylindrical mesh basket 400 is rotated at any rotational position, that is, the mesh basket 400 ends at any position where the rotation of the mesh basket 400 ends. The basket 400 can be gripped smoothly and easily.
