Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for barrel-plating electronic components such as chip resistors, for washing and drying the barrel-plated electronic components.

[Problems to be solved by conventional techniques and ideas]

Generally, in electronic components such as chip resistors, a metal plating layer of nickel or tin is applied to the surface of the terminal by barrel plating, and the electronic components after barrel plating are washed with water and dried. Move on to the next process.

Conventionally, electronic components are washed and dried manually after barrel plating, which is extremely inefficient and increases the cost significantly. During the handling of washing and drying electronic components, the electronic components often rub against each other, causing damage to the electronic components, which also causes a problem in that the yield rate of the product decreases.

The present invention provides a washing/drying device that mechanically washes and dries electronic parts after barrel plating with less damage to the electronic parts.

[Means to solve the problem]

In order to achieve this objective, the present invention uses a washing tank in barrel plating equipment in which a rotating barrel is immersed, and a centrifugal separator in which a top-open case is rotated, separated by an appropriate distance. A trolley for reciprocating between an area directly below the washing tank and a side area of the centrifugal dryer is provided below the washing tank, and the cart includes a washing tank. A top-open type receiving tank filled with water is installed, the housing is removably inserted into the receiving tank, and a discharge valve into the housing in the receiving tank is provided at the bottom of the washing tank. On the other hand, on the side of the centrifugal separator, there is provided an overturning mechanism for overturning the casing into the hopper, and further above the centrifugal separator, the casing is installed. A transport mechanism is provided for transporting the liquid from the receiving tank to the centrifugal separator and from the centrifugal separator to the overturning mechanism.

[Effect]

In this configuration, when the rotary barrel that has completed the plating process in the barrel plating equipment is rotated with the lid opened while immersed in the washing water in the washing tank, the electronic components inside the rotary barrel will be washed under water. It is discharged into the washing tank while being washed.

Next, by opening the discharge valve at the bottom of the washing tank with the trolley positioned directly below the washing tank, the electronic components in the washing tank are removed together with some of the washing water in the washing tank. Then, it is dropped into the container inside the receiving tank. In this case, since water for washing is contained in the receiving tank,
The electronic components can be dropped into the housing underwater, and the electronic components can be washed with water.

In this manner, when the electronic components have been completely dropped into the housing in the receiving tank on the cart, the cart is moved from the lower part of the washing tank toward the centrifugal separator. Next, when the cages in the receiving tank on the trolley are lifted out of the receiving tank by the transport mechanism and transferred to a centrifugal separator, the cages are rotated at high speed by the centrifugal separator. By doing so, the moisture adhering to the electronic components is shaken off and the electronic components are dried.

After drying in the centrifugal separator is completed, the cage is transported from the centrifugal separator to the overturning mechanism by the transport mechanism, and then overturned into the hopper by the overturning mechanism, so that the inside of the case is Electronic components can be ejected into the hopper.

[Effect of idea]

Therefore, according to the present invention, the electronic components in the rotary barrel are discharged from the rotary barrel into the housing, the electronic component-containing housing is transported to a centrifugal separator, and the electronic components are removed from the housing. Since it is possible to mechanically transport the electronic components from the centrifugal separator to the overturning mechanism and furthermore to discharge the dried electronic components from the housing, the electronic components after barrel plating can be This makes it possible to automate the process of rinsing, drying, and sending the electronic components to the next process, greatly improving efficiency. Since dropping into the body is carried out in water for washing, damage to electronic parts that occurs when electronic parts are ejected from the rotating barrel and dropped into the housing can be significantly reduced, resulting in improved product yield. It has the effect of improving the rate.
