Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a transfer device for an object to be coated, which transfers resin, paint, etc. to small parts such as a printed circuit board.

2. Description of the Related Art Conventionally, when resin or paint is applied to small parts such as a printed circuit board or when an object to be coated is transferred immediately after the application, the resin or paint applied to the object to be adhered adheres to the transfer device. In many cases, it is difficult to remove the object to be coated from the transfer device or to operate the transfer device. Such a state is caused by a large contact area between the object to be coated and the transfer device and that the movable part of the transfer device is exposed to the spray nozzle of the applied product.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention is intended to solve the problems as described above, and in the case of applying a coating material such as a resin or a paint onto a coating material such as a printed circuit board or a small component by spray coating, The contact area between the coating material and the transfer device can be reduced and contamination of the movable part of the transfer device can be prevented, so that good transfer can be achieved.

Means for Solving the Problems In order to solve the problems described above, the present invention provides a plurality of support protrusions for supporting an object to be coated with an injection nozzle of the object facing the upper surface from both sides of the lower surface at regular intervals, The support protrusion is provided so as to project inwardly of a pair of transfer members provided with a facing interval, the upper surface of the transfer member is covered with a coating plate, and the inner edges of the coating plate are applied to both ends of the object to be coated. They are arranged so as to face each other, form a small non-contact gap between the inner edge and the object to be coated, and cover the inner edge of the cover plate so as to face the upper end of the support protrusion.

Further, the support protrusion may be formed in a cylindrical shape.

Function Since the present invention is configured as described above, if both ends of an object to be coated such as a printed circuit board or a small component are placed on the upper surfaces of a plurality of support protrusions, a plurality of support protrusions are provided at regular intervals. Therefore, the contact area between the object to be coated and the transfer device is small, and even if resin, paint, etc. adhere between the support protrusion and the object to be coated, the support protrusion and the object to be coated are easily separated. It can be done without sticking.

Further, the upper surface of the transfer member having the supporting projections is covered with a covering plate, and the inner edges of the covering plate are arranged so as to face both ends of the object to be coated, and the inner edges are exposed to the upper ends of the supporting projections. Since it is covered by the coating, the supporting protrusions are not exposed from the placed object to be coated. Therefore, even if the coating object is sprayed from the spraying nozzle facing the upper surface of the coating object, the coating object is less likely to adhere to the supporting projections, the supporting projections are not contaminated, and the supporting projections and the coating object are not contaminated. Even if the applied material adheres between them, it is possible to prevent sticking as described above.

Further, if the supporting protrusions are formed in a cylindrical shape, the object to be coated and the supporting protrusions are in line contact with each other, and the contact area can be made small. Therefore, even if the object to be coated and the supporting protrusions adhere to the object to be coated, they are fixed. There is no such thing, and it can be easily separated.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. (1)
Is a support protrusion, and a plurality of protrusions are provided at a constant interval (4) inside a pair of transfer members (3) such as chains provided with a facing interval (2) between them. The coated article (5) is formed in a cylindrical shape so that it can be supported from both sides of the lower surface.

Further, the support protrusion (1) is formed by projecting a pin or the like that constitutes the transfer member (3), and the placed object (5) is placed.
On the upper surface of the, spray nozzle (7) of the applied material (6) such as resin and paint
It is located facing.

In addition, a transfer member provided in a ring shape in the vertical direction with a space therebetween.
The upper surface of the upper part of (3) is covered with a cover plate (11) protruding from the side wall (10) of the base (8). Then, the inner edge (12) of the cover plate (11) is arranged so as to face both ends of the object to be coated (5) placed on the support protrusion (1) and the inner edge of the cover plate (11) ( 12)
To cover the upper part of the support protrusion (1). Further, the facing interval of the inner edge (12) is set to the placement interval (13) of the object to be coated (5).
I am trying.

Also, the inner edge (12) of the cover plate (11) and the object to be coated (5) are opposed to each other by providing a slight non-contact distance between the object to be coated (5) and the inner edge (12), and thus the pointing protrusion The movement of the article to be coated (5) placed on (1) should not be hindered.

By covering the cover plate (11), the transfer member (3) and supporting protrusions
Contamination by the coating material (6) of (1) is prevented. Further, by bending the inner edge (12) of the cover plate (11) toward the support projection (1) side as shown in FIG. 1, it is possible to further ensure the prevention of contamination by the coating material (6).

Further, the upper surface of the support protrusion (1) located in the lower part is covered with a lower cover plate (15) provided by connecting from the inner wall (14) of the base (8),
In the same manner as above, it is possible to prevent contamination on the coated article (6).

In the structure configured as described above, in order to apply the coating object (6) to the coating object (5) such as a printed circuit board or a small component, the support object (5) has a plurality of support protrusions ( Place on top of 1).
This placing method may be performed via a conveyer such as a conveyor that is connected from the previous step, or may be performed manually. Further, the object to be coated (5) has a cover plate (11) at both ends.
It is placed on the support protrusion (1) so as to face the inner edge (12) and not come into contact.

After the placement of the article to be coated (5) on the support projection (1) is completed, the article to be coated (6) is jetted from the jet nozzle (7) while the transfer member (3) is operating or in a stopped state. The object to be coated (5) is applied. In this coating operation, the supporting projections (1) are provided at a plurality of fixed intervals (4) and have a cylindrical shape, so that the contact area between the object to be coated (5) and the transfer device (16) is It will be small.
