Description

  The present invention relates to a module-type guard rail for guiding a plating substrate, which guides a thin substrate to be plated during a substrate online plating operation in a plating tank containing a plating solution. In particular, the present invention relates to a module-type guard rail for guiding a plating substrate, which can be installed in a deformable manner, and can prevent a sway and a scratch while improving the flow of a plating solution.

  As is well known, in electroplating, among the plating methods, an electrode is put into a solution containing metal ions and an electric current is caused to flow, thereby discharging and depositing metal ions from a cathode. Utilizing this, a thin metal film is formed on the surface of the article placed on the cathode.

  The general process of such electroplating proceeds in the order of dehydration → polishing → degreasing → chemical immersion treatment → electroplating → post-treatment → drying.

  The substrate to be plated is immersed in the plating tank, and electroplating is carried out in an on-line state (continuous processing). At this time, the vibration of the substrate to be plated and scratches such as scratching of the substrate are prevented. For this purpose, a guardrail for guiding the board is provided.

  Conventionally, a guardrail that plays such a role has a fixed guardrail structure installed in a plating tank, so that it is difficult to change the guardrail after installation by changing the work process. For this reason, they have been discarded and cannot be reused.

  In addition to the problem of fixed installation, the plating solution flow cannot be guided smoothly in the plating tank. There are disadvantages such as an increase in the defective rate of a plated substrate such as a scratch, and the inability to effectively eliminate deviations in substrate swing.

  In addition, the present invention was devised to solve the above-mentioned conventional problems. It is an object of the present invention to provide a module-type guard rail for guiding a plating substrate, which can improve plating efficiency, reduce a plating defect rate, and can be variably assembled and disassembled as required.

  In order to achieve the above object, the present invention is directed to a plating board guide guardrail which is installed in a plating tank containing a plating solution and guides a board to be plated in an on-line progression style and prevents shaking. A plurality of inclined grid guides having a flow path for the plating solution are provided in parallel with the same climbing interval (interval in the rising direction) along the traveling direction of the substrate. The vertical holding bases on both front and rear sides are connected to the upper and lower horizontal holding bases. Further, in the lattice guide, the guard holding pin serving as an entrance for entering the substrate is formed in a triangular shape.

  As described in detail below, the modular guardrail for guiding a plated substrate according to the present invention has the following advantages.

  (i) Prevent the substrate from swaying during the on-line plating work in the plating tank.

  (ii) Scratching of the substrate, such as scratching, is prevented, and plating defects are reduced.

  (iii) Eliminate plating deviations.

  (iv) It has a structure to maintain the flow of the plating solution well.

  (v) Modular structure that can be applied to various sizes as a modular structure.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  1 to 3 are a front view, a side view and a plan view showing a structure of a module type guard rail for guiding a plated substrate according to the present invention.

  The present invention provides a guard rail for guiding a plating substrate (1), which is installed in a known plating tank (not shown in the drawing) and guides the substrate (1) to be plated in an on-line traveling manner to prevent shaking. An inclined grid guide portion (3) having a plating solution flow passage (2) is arranged in parallel at the same ascending interval along the traveling direction of the plating solution. The vertical holding table (4) is connected to the upper and lower horizontal holding tables (5a, 5b). Here, the guard holding pins (6) forming the entrance of the lattice guide (3) into the substrate are formed in a triangular shape, and have a structure that can be easily attached and detached.

  Here, the side of each of the lattice guides (3) has a smooth and smooth round surface (3a) (the cross-section is a curved or arc-shaped curved surface that swells smoothly, and the surface is caught. This prevents the scratching of the substrate (1) when it comes into contact with the moving substrate (1) during the plating operation. The material is polypropylene (PP), polyethylene (PE) or polyvinyl chloride (PVC).

  An anchor (7) is formed on the lower horizontal support (5b) that supports the lattice guides (3) so that the anchor can be installed in the plating tank.

  The modular guard rail for guiding the plated substrate according to the present invention, which is configured as described above, is disposed in the plating tank as shown in FIGS. With the two module-type guard rails installed in parallel, the substrate (1) to be plated is moved by a well-known hanger rack in the direction of the arrow (A), which is an online traveling path system of these guard rails. . At this time, the module-type guard rail prevents shaking, and the plating solution flows freely through the plating solution flow passage (2) formed between the lattice guides (3) during plating, and the substrate ( 1) Helps smooth plating.

  On the other hand, when the substrate (1) passes between the lattice guides (3), the tip of the lattice guide (3) has a very smooth and rounded round surface (3a), and the substrate is in contact with the substrate. Even so, scratches are not generated on the substrate (1).

  In addition, the material of the guardrail according to the present invention can be variously changed to polyethylene, polypropylene or PVC depending on the chemical of the plating solution to be plated. In addition, the present invention is manufactured in a modular form, and when several are connected in series as shown in FIG. 3, it is a variable type that can be variously changed in a plating tank.

FIG. 3 is a front view of a module type guard rail for guiding a plated substrate according to the present invention. FIG. 2 is a side view of the modular guardrail shown in FIG. 1. It is a top view of the guardrail of the present invention installed continuously as a module type in a plating tank. FIG. 4 is a schematic view illustrating a usage state of the modular guardrail of the present invention.
