Abstract

PURPOSE:To improve productivity, to improve production capability and to make the state of application uniform by lifting a container with a feed stock conveyer for conveyance in an apparatus, applying resin in a resin liquid tank, conveying the container to a dry to touch stock conveyer, blowing adjustable hot air to a resin-application agent material, and agitating the material. CONSTITUTION:A container 17 filled with electronic components is mounted on a side roller chain 2 of a feed stock conveyer 1. The container is conveyed and stopped at the terminating end of the conveyer. The handles of the container are immediately chucked with pawls 6 of an applying unit. The container is moved up and down in a resin liquid tank 10, and the resin is applied. Thereafter, the container is conveyer to the tip end of a natural drying stock conveyer 9. The container 17 is conveyed to the upper part of an agitating device 7. A splash preventing cap 8 is closed. Hot air is blown through a nozzle 14, and agitation is performed for a specified time. Then, the container 17 is conveyed to the terminating end of the dry to touch stock conveyer 9. Said operation is repeated. When, the conveyer 9 is filled with the containers 17, the apparatus is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a surface treatment device for the purpose of protecting, moisture-proofing, and insulating the resistance film of electronic components such as film resistors.

2. Description of the Related Art Conventionally, as shown in FIG. 4, when performing surface treatment on a large number of electronic components 17 at the same time, a fixed amount of electronic components are placed in a resin coating container 18 (FIG. The resin was applied with a machine (Fig. 0), then dried to the touch using a hot air blowing method or a suction method on the stocker 20, and then baked in a dryer. d).

Problems to be Solved by the Invention However, according to these methods, when trying to improve productivity and increase production volume, it is difficult to improve productivity because it requires manual work. In addition, this work is physically taxing, and if the resin liquid contains organic solvents, it is not good for the human body and poses environmental problems, and there may be variations in the state of resin coating on the surface of electronic components. It was occurring.

Means for Solving the Problem In order to solve this problem, the present invention uses a wire mesh container as a conveying coating container, places the containers in multiple rows in parallel on a supply stock conveyor, and when the device is operated, automatically Resin coating is carried out, and after coating, the workpieces are efficiently dried to the touch, warm air is blown onto the workpieces to agitate the coating, and the workpieces are stocked on a dry-to-the-touch conveyor.

Due to the structure with the action, the operator only has to work on supplying the material.
Since the combined materials are stirred, the drying time to the touch can be shortened and the resin can be applied uniformly.

EXAMPLES The present invention will be explained in detail below based on examples shown in the drawings.

FIG. 1 is a perspective view of a surface treatment apparatus according to an embodiment of the present invention, FIG. 2 is a perspective view of a transporting resin coating container, and FIG. 3 is an explanatory diagram of the operation of a stirring device.

The surface treatment apparatus of this embodiment includes a supply stock conveyor 1 equipped with a motor-driven chain 2 with side rollers as a horizontal conveyance means for the containers 17, and a motor-driven chain 3 and vertical conveyance as the horizontal conveyance means for the containers 17. As a means, a cylinder 4 driven by air
and slide unit 6, and further slide unit 6
A coating unit 13 equipped with a container handle chucking claw 6 inside, lifts a container 17 from the end of the supply stock conveyor 1, applies resin in a resin liquid tank 1o, and transports the container 17 with a casing at the tip of a dry-to-touch conveyor 9. and Rg17
As a horizontal conveyance means, it is equipped with a motor-driven chain with side rollers, a stirring device 7 that blows warm air from a nozzle/L/14 for stirring, and a lid 8 that is buttoned on the stirring part and is intended to prevent materials from scattering. , exhaust duct 1 at the bottom
2 and a resin liquid tank 10 equipped with a shutter 11 driven by a motor chain.

With the above configuration, when the container 17 filled with electronic components is placed on the side roller chain 2 of the supply stock conveyor 1 and the apparatus is operated, the container 17 is conveyed and stopped at the end of the conveyor. Immediately thereafter, the container handle is chucked by the coating unit claw 6, and the resin liquid tank 10
Resin coating is performed by moving up and down at the top. At this time, the shutter 11 of the resin liquid tank 1o is opened only when applying the resin. After the resin is applied, it is temporarily on standby on the resin liquid tank 10, and then transported to the top end of the natural drying stock conveyor 9.

The transported container 17 is further transported to the upper casing of the stirring device 7 by the side roller chain 2, and the scattering prevention lid 8 is closed 1 to perform stirring drying.

The stirring device is an air cylinder 15 as shown in Figure 3.
Then, the motor drive chain 16 repeats the trajectory motion shown by the broken line while blowing hot air from the nozzle /L/14. However, in the stirring method, a means for stirring by inserting a stirring screw into the container while blowing hot air may be added.

After stirring for a certain period of time, the container 17 is conveyed to the end of the dry-to-touch stock conveyor 9.

The above-mentioned operations are repeated, and when the dry-to-touch stock conveyor 9 is filled with containers 17, the equipment is stopped.

Effects of the Invention As described above, according to the present invention, since it is only necessary to supply materials to the supply stock conveyor, human and environmental problems can be solved, and productivity and production capacity can be improved. Furthermore, since the resin is stirred after being applied, the coating state can be made uniform, leading to improved quality.
