When plating IC lead frames and other strip-shaped parts, it is necessary to plate a large amount of plated objects in a short period of time. In general, plating can be roughly divided into three steps: a pre-treatment step, a main plating step, and a post-treatment step, and the processing speed of the entire line is determined by the processing speed of each step. Here, the pre-treatment process includes treatments such as electrolytic degreasing, washing with water, neutralization, and strike plating, which are carried out before the main plating process, and the post-treatment process includes washing with water, which is carried out after the main plating process,
This includes treatments such as alkali and pure water washing. Many plating processing apparatuses have been developed and proposed that can carry out each of these processes continuously, but the processing speed of the entire line is relatively slow and the results have not been satisfactory. A person places multiple strip-shaped plated items in advance on a trolley, uses the trolley as a rack, and transports the plated items together with the trolley, automatically plating a large number of plated items efficiently. We have previously proposed a device to do this (see Japanese Unexamined Patent Publication No. 56-99127).

Although the proposed plating equipment has considerably improved processing speed compared to conventional plating equipment, it is difficult to change the processing speed at a higher speed because the plated material is transported via a trolley, and it is difficult to change the processing speed at each plating process. It was necessary to prepare devices with different structures for each process. The present invention aims to provide a lead frame plating processing apparatus that uses a group of feed rollers instead of a trolley and has a high processing speed in which the lead frame being conveyed by the group of feed rollers is subjected to processing according to the treatment tank. It is something to do.

- A preferred embodiment of the present invention will be described below with reference to FIGS. 1 and 2. This example shows a case where it is used for strike plating in a pretreatment process. 1 is a processing tank, and the processing tank 1 is filled with a strike plating solution 2 as a "processing solution". In this processing tank 1, a nipping roller 3 as a "feeding roller group" is provided.
a, 3b, a cathode roller 4, and a backup roller 5, respectively. The pinching rollers 3 are a pair of upper and lower parts.
They are arranged in the inlet slit 6 portion, the interior center portion, and the outlet slit 7 portion of the processing tank 1, respectively. Also, the lower pinching roller 3 among the pinching rollers 3a and 3b
b is a grooved roller as shown in FIG. 2, and is designed not to come into contact with the plated surface 9 of the lead frame 8, which is the plated object. The distance between the strings of the holding rollers 3a and 3b, of which there are three pairs (one upper and lower pair), is set to be at least shorter than the length of each lead frame 8 so that the lead frames 8 can be conveyed sequentially. The two cathode rollers 4 are used to cathode the lead frame 8, and are arranged between a pair of upper and lower backup rollers 5 so as to be rotatable. In addition, a pair of upper and lower liquid leak prevention pipes 10 are arranged close to each other at the input/output side slit 6.7.
Care is taken to prevent the strike plating solution 2 inside from leaking. Although not shown, there is a possibility that the strike plating solution 2 may leak, so in such a case, it is common practice to provide a reservoir on the outside of the inlet and outlet sides of the processing tank 1 and collect the solution from there. 1.
Reference numeral 1 denotes a plating prevention casing, which is provided for the purpose of preventing plating from adhering to the cathode roller 4. Further, Mi 12 is a mesh-like anode. Therefore, the lead frame 8 sent from the front processing tank 13 to the inlet slit 6 of this processing tank 1 is transferred to the feeding roller group, that is, the nipping rollers 3a, 3b, cathode rollers 4, etc.
, while being transported horizontally within the processing tank 1 by the backup rollers 5, and while being transported, processing according to the processing tank 1,
In other words, strike plating is applied. Then, after the strike plating process is applied, the exit side slit 7
From there, it is sent out to another processing tank 14 on the next rear side by the same "feeding roller group". In this embodiment, the strike plating process is performed by filling the processing tank 1 with the strike plating solution 2. If it is kept in a tank, it can be washed with water, or if acid is added, it can be pickled, and of course, a plating solution can be added to perform the main plating process, and various post-processing processes can be performed in each treatment tank. It is also possible.

It is highly versatile as it can perform the necessary treatments while being transported in the treatment tanks for each treatment such as the pre-treatment process, main plating process, post-treatment process, etc., and this equipment can be installed in series. It is also possible to configure an entire plating process line.
