Description

Continious barrel plating machine

The present invention relates to a continuous barrel plating machine, and more particularly, to a barrel plating machine capable of continuously plating.

In general, barrel plating is a method of plating a large number of small articles at a time, and the articles and the articles are frictionally polished by contact with each other and the current is interrupted and the plating is performed by the contact of the cathode rod, and the plating apparatus is horizontal and There are two types of inclinations, which are used for plating small objects or small quantities.

The plating process is divided into pre-treatment, plating process, and post-treatment of plating. The plating pretreatment process involves polishing a metal to be plated to smooth out uneven portions of the surface, a pickling process for removing oxides or hydroxide salts from metal surfaces, or removing rust, and an oxide attached to the metal surface. , Degreasing process to remove contaminants such as hydroxides, metal salts and oils and fats.

In addition, as a post-treatment process, the plated metal divided into water washing and drying processes is washed with water over several times, and then dried to become a finished product.

Of course, when gloss is required on the surface, it is polished after washing with water, and even when chromate treatment is required such as galvanizing, chromate treatment after drying is performed to obtain a finished product.

Electroplating is mainly used for electroplating. Electroplating is a process of depositing and coating other metals on the metal surface by electrolysis to protect or beautify the surface. It is common to plate with the salt solution of as an electrolyte, but sometimes an insoluble anode such as lead or carbon is used. It is known that the properties and protective effects of the deposited metal depend on the thickness of the plating layer, the type of electrolyte, the stirring state, the current density, and the like.

On the other hand, the conventional plating apparatus for plating using a barrel plating machine is equipped with a barrel 120 to be rotated inside the tank 110 made of an insulator as shown in Figure 1 and the + current is energized above the barrel 120 The pole plate 131 connected to the + pole plate 130 is in contact with the inside of the barrel has a structure that is provided with a cathode rod 140 through which the outside of the-current.

Of course, the plating liquid 150 is filled in the tank, and a plurality of through holes 124 are formed on the surface of the barrel so that the plating liquid is introduced into the barrel, and an object inlet is provided on the barrel so that the plating object can be introduced and discharged. do.

Therefore, when plating is performed using the barrel, there is a difficulty in opening the inlet of the barrel to charge the plating object into the barrel, and after plating by electrolysis, discharge the plated object in the barrel to the outside.

In particular, in order to withdraw the plated object in the barrel is required to discharge the plating liquid takes a long time during the plating operation and there is a difficulty in working.

As a method for solving the above-mentioned problem, a method of detaching the barrel from the tank, lifting the barrel upward and pulling out the plated object after the plating is completed using a hoist or a crane is used. However, this method has the advantage of being able to withdraw the plated object from the barrel without discharging the plating solution, but also the process of charging and withdrawing the plated object in the barrel is the same to charge the plated object using a manpower, Withdrawal, the difficulty of working and the long time problem exist.

Therefore, the technical problem to be achieved by the present invention is to provide a barrel continuous plating machine of the shape that can be connected to the post-process, the plating object is automatically charged and withdrawn in the barrel to solve the above problems.

The above-described technical problem can be achieved by moving the plating object forward through the plating liquid and withdrawing the outside by rotating the barrel, and allowing the electrode inserted into the barrel to be energized even when the barrel rotates.

A plating liquid tank formed of an insulator,

It is installed to be rotated in the tank, connecting the inlet and the outlet provided in the front and rear, the inner circumferential surface is provided with a screw groove and the outer surface of the barrel provided with a plurality of through holes,

A + electrode plate inserted into the barrel and in contact with a plating solution and connected to an outside + power source;

An electrode pole inserted into the barrel and in contact with a plating object and connected to an outside power source;

Plating object is inserted into the barrel outlet inclined to be drawn out is made of a drawer that is drawn out to slide out.

Referring to the drawings according to an embodiment of the present invention as follows.

2 is a schematic front view of a barrel continuous plating machine related to the present invention,

3 is a side cross-sectional view of a barrel continuous plating machine according to the present invention.

As shown in FIG. 2, the barrel 20 is supported by a support roll 27 fixed to the bottom of the plating liquid tank 10 made of an insulator by a support 28 formed around the gear 20. 29 is formed, and is engaged with the upper driver (not shown) to rotate.

In addition, the inlet 21 and the outlet 22 are provided at both sides of the barrel 20, the inner peripheral surface of the barrel 20 is formed with a screw groove 23 for connecting the inlet and the outlet, at the end of the screw groove A plurality of separators 26 (see FIG. 3) are formed to extend and divide the inner circumferential surface along the rotational direction, and the receiving part 25 receives the plated object falling from the screw groove between the inner circumferential surface of the expanded barrel. On the other hand, a plurality of through-holes 24 are formed on the outer surface of the barrel 20 to allow the plating liquid to flow in and out.

In the inner space portion of the screw groove 23 provided in the barrel 20, a + pole rod 30 that is energized by an external + power source is inserted, and is spaced apart from the + pole rod 30 by a distance to the outside-power source. An energized pole electrode 40 is inserted, and a plurality of hooks 41 are formed in the pole electrode 40 to improve contact with the plating object.

The charging stand 60 is inclined downward from the outside into the inlet 21 of the barrel, and the lead 70 inclined downward toward the outside is inserted into the outlet 22.

The following describes the operation.

When plating using the barrel continuous plating machine of the present invention, the plated object is

When placed on the charging stand 60 inserted in the (21) is drawn into the barrel 20 by the inclined surface. The drawn plating object is charged in the screw groove 23 formed on the inner circumferential surface of the barrel and moved to the outlet 22 through the plating liquid by the rotation of the barrel.

While the plating object is inserted into the screw groove 23 and moved, the + pole rod 30 and the pole rod 40 inserted into the barrel are energized so that the + pole rod is dissolved in the plating solution, so that the pole pole 40 and the pole rod It is coated and plated on a plated object that is in contact with the hook.

While the plating coating of the plating object is completed, the plating object is divided by the separator 26 provided in the receiving portion 25 of the barrel outlet 22, and is moved upwards according to the rotation of the separator. It is dropped to the outside through the transfer to the subsequent process.

Therefore, the barrel continuous plating machine of the present invention not only enables the plating continuously, but also allows the automatic drawing of the plating object into and out of the barrel.

Of course, the present invention is not limited only to the above-described embodiment, and in view of the plating speed, a plurality of positive electrode plates may be installed in the tank, and the above-described barrels may be connected and used.

According to the present invention, the plating object is automatically charged into the barrel, and after plating, the plating object can be automatically drawn so that the plating can be performed continuously. Therefore, the difficulty of drawing and removing the plating object into and out of the barrel by hand can be solved. It works.
