Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an electroplating apparatus, and more particularly, to a roll feeder type electroplating apparatus for transferring a plating material by sandwiching the same between upper and lower rolls.

[0002]

[Prior art]

 In the conventional electroplating method, a large number of pieces of plated material are sandwiched one by one at a first position, which is a preparation position, by a large number of chucks, and the chucks are connected to an overhead crane, and the multiple pieces are plated by the overhead crane. The materials were transported all at once to each electroplating tank to perform electroplating. When the overhead crane reaches the upper part of the electroplating tank, the plating material is immersed in the electroplating tank at the same time as the chuck to perform electroplating. Simultaneously from the electroplating tank, remove the entire plating material from the chuck and place it in the second location, after which the overhead crane returns to the first location and performs electroplating for the next plating material group. After the electroplating of all the plating materials is completed, the plating materials for which the electroplating has been completed are transferred from the second location, and the work in the following steps proceeds. There are drawbacks such as: (1) A considerable amount of labor and work time is required because the plating material must be manually held between the chucks or removed from the chucks. (2) After the electroplating of one group of plating materials is completed, the electroplating of the next group of plating materials can be performed, so that the electroplating cannot be performed continuously. (3) In the event that several layers of metal plating are to be performed on the plating material, since all the materials to be plated have completed the same layer of electroplating, the next layer of electroplating can be performed. If it is not possible to proceed with the electroplating work, and if multiple layers of metal are to be plated on the material to be plated, the chucking work on the plated material and the work of removing it from the plated material must be performed many times. In particular, it requires extra labor and time. (4) Since the chuck is a cathode similarly to the plated material, when the plated material is electroplated, the chuck is also plated with a metal layer, so that the operation is stopped every predetermined time. The reverse electrolysis must be performed to remove the metal layer plated on the chuck surface, which affects the progress of the electroplating operation and is considerably troublesome.

[0003]

[Problems to be solved by the invention]

 In view of the above-mentioned problems in the transfer of the plating material in the conventional electroplating, the present invention transports all the plating materials by sandwiching them between the upper and lower rolls, and performs the clamping operation of the chuck of the conventional technology on the plating materials. Rolls that can save time and labor, and can eliminate the reverse electrolysis work on the chuck and can apply one or more layers of electric plating continuously to all plating materials. An object of the present invention is to provide a feeder type electroplating apparatus.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an inlet and an outlet corresponding to each other on both end surfaces thereof to form a horizontal plating material transfer passage therein, and is separated by the transfer passage. A plating solution upper injection port and a plating solution lower injection port are respectively opened on other appropriate wall surfaces of the lower portion so that the plating solution is sprayed on the plating material passing through the transfer passage, and the upper and lower portions of the transfer passage are provided. One or more anode jet tanks each having a plating anode plate provided therein, and a plurality of anode jet tanks provided above and below the plating material transfer passage of the anode jet tank adjacent to the anode plate, respectively. A double-sided mesh plate that separates the plating material from each other so as to prevent short-circuiting due to contact with the plating material, and sealers attached to both sides of the inlet and outlet of the anode jet tank, respectively. It comprises a cathode row La provided roller and the other side of the sealing rollers, ing and a transport roller set used to transfer the plating material.

[0005] The anode jet tank includes an upper tank and a lower tank, and forms a channel between the upper tank and the lower tank as a passage for a plating material. It is more preferable that a feed port and a feed port are provided for each of the anode plates, and the anode plate is provided in the upper tank and the lower tank, respectively, and a mesh for ejecting a plurality of plating solutions is provided on the anode plate.

In the present invention configured as described above, the anode plate, the material to be plated, and the cathode roller form one conductive circuit by the conductivity of the plating solution, and the metal ions in the plating solution are applied to the surface of the plating material. Electroplating can be advanced by reductive precipitation. Further, since the plating material is transported by the sealing roller and the cathode roller, it is possible to omit the operation of clamping the plating material by the chuck in the related art. Therefore, the number of anode jet tanks and transfer roller sets can be elastically increased or decreased according to the number of metal layers to be electroplated on the plating material, and continuous electroplating can be performed. Further, since the cathode roller is provided outside the anode jet tank and is not in contact with the plating solution by separating the sealing roller, it is possible to prevent the cathode roller from being electroplated at the same time.
