Depending on the size of the object to be plated, it is possible to produce various objects to be plated by adjusting the spacing of the object to be plated by easily replacing the clip when plating is in progress. Regardless of the size of the object to be plated, it is possible to adjust the amount of chemical liquid in the tank tank, so that the plating thickness between the object to be plated can be maintained uniformly, thereby improving the efficiency of work. will be.

In general, plating is coating with a thin layer of other materials for the purpose of improving the surface condition of an object. Such plating includes electroplating, chemical plating, hot dip plating, etc. Among these platings, electroplating is the object to be plated in an electrolytic solution. As a cathode, it is used for various purposes such as decoration or anti-rust function, and is used for various parts or accessories because it is relatively inexpensive and can provide an appropriate metal film.

The above electroplating is divided into a barrel method, a rack method, and a rotary method. It is usually called a'barrel'. A large amount of the object to be plated is injected into a cylinder with a number of holes for energization and passage, so that the barrel is immersed in a plating bath, and the barrel is gradually immersed in the barrel. It is a plating method suitable for the object to be plated which is relatively small in volume by plating while rotating.

In the rack method, the object to be plated is plated by hanging the object to be plated on a rack for plating, commonly referred to as'rack'. There is an advantage of excellent plating quality because a certain gap is maintained between gold objects.

The transfer unit 1 is formed to be rotated by a driving unit not shown so that the entire plating apparatus is energized to the cathode so that the object to be plated can be sequentially reached from the ultrasonic unit 2 to the drying unit 10.

The transfer unit 1 is a frame (F) left and right front and rear to rotate the transfer belt (V) connected by a plurality of metal pieces formed with a hook hole (H) in the center as shown in Figs. A driving pulley 11 is formed in pairs, and a stop pulley P'is formed between a pair of guide pulleys (P) and the guide pulley (P) on the right side of the left front driving pulley (11). (11) and the stopping pulley (P') are formed to move in the left and right sides and forward and backward, and the discharge part 300 at the rear of the left rear driving pulley 11, and between the left front driving pulley 11 and the guide pulley P To form an input part 400.

The left front driving pulley 11 and the stopping pulley P'of the transfer unit 1 are installed on the control plate 13 which is moved to the left and right sides and the front and rear sides along the rail 12 by the cylinder S.

The driving pulley 11 and the stopping pulley P'of the left front side are installed on the control plate 13 which is moved to the left, right and front and rear along the rail 12 by the cylinder S.

A plurality of tension adjustment pulleys 14 and close contact pulleys 15 are installed to adjust the tension of the transfer belt V and drive without vibration to the right of the driving pulley 11 on the left front side as shown in FIG. 6. It is preferable to elastically install a fixing plate 17 formed on the frame 16 and fixing the close contact pulley 15 by a spring.

In addition, the hook hole (H) of the transfer belt (V) that rotates to move the plated object to the input unit 400 and the discharge unit 300 has a ring (C') on which the plated object is caught is formed on the lower side. It is fixed by forming a clip (C) on the upper side.

The discharge unit 300 is formed to separate the plated object by raising the plated object by forming a separation guide protrusion 301 for separating the plated object stuck in the transfer belt (V) on the frame (F). The plated object is formed to be discharged through the discharge conveyor 302.

Meanwhile, the input part 400 forms an input conveyor 401 between the left front driving pulley 11 and the right guide pulley P, and the input belt 402 of the input conveyor 401 has a transfer belt (V). ) To form the receiving groove 403 of the same distance as the distance of the hook hole (H).

In order to plate the object to be plated that is injected and rotated in this way, it is transferred to each tank.

Each of these tanks is the first and second ultrasonic degreasing tank 21, the first electrolytic degreasing tank 31, the second electrolytic degreasing tank 32 and the chemical polishing tank ( 41), the pickling tank 51 and the metal plating tank 61, the post-treatment tank 71 and the hot water tank 81 form a moving groove 40 in which the transfer belt V is moved to the left and right, and the movement A plurality of fixing bolts 42 are formed outside the groove 40 and a blocking plate 44 having a long hole 43 into which the fixing bolt 42 is inserted is formed, and is fixed with a nut 45.

The operation and effect of the present invention configured as described above will be described as follows.

First, when the object to be plated is placed in the receiving groove 402 formed in the input conveyor belt 401 of the input unit 400, the object to be plated is aligned and the object to be plated is moved to the left front driving pulley 11 and the left guide pulley (P). ) To be caught in the hook (C') of the clip (C) hanging on the transfer belt (V).
