Description

Technical Field

[0001] The utility model relates to the technical field of production equipment for iridescent films, and particularly relates to an evaporation tank for electroplating generation of iridescent films. Background Art

[0002] The existing invention patent with the application number 201910021947.3 discloses an improved evaporation tank for an iridescent film electroplating process. It forms a molybdenum boat by connecting molybdenum bars in an S shape, which is used to accommodate stacked electroplating materials, and is equipped with silicon carbide columns for limiting. However, since the electroplating materials include stacked parts, the materials on the upper part do not contact the molybdenum boat. When electrified, the evaporation efficiency of the upper materials will decrease, thus affecting the electroplating efficiency of the iridescent film. At the same time, the structure of the molybdenum boat is fixed and cannot be adjusted, which has limitations in accommodating the quantity of materials during use. On the other hand, a cushion block is provided under each group of molybdenum boats, resulting in a problem of resource waste. Content of the Utility Model

[0003] The purpose of the utility model is to provide a structure of an evaporation tank that ensures stable, efficient, and convenient evaporation of electroplating materials for iridescent films in view of the deficiencies in the above-mentioned background art.

[0004] To achieve the above purpose, an evaporation tank for electroplating generation of iridescent films of the utility model adopts the following technical scheme:

[0005] An evaporation tank for electroplating generation of iridescent films includes a tank body and a cover plate disposed above the tank body. First copper column electrodes and second copper column electrodes are respectively provided on two tank walls of the tank body, and the first copper column electrode and the second copper column electrode are staggered. A support cushion block is arranged at the bottom of the tank body, and a molybdenum boat structure for placing electroplating materials for iridescent films is supported above the support cushion block. The molybdenum boat structure includes at least three V-shaped plate grooves, and adjacent plate grooves are connected by a connecting part. The connecting part is a connecting plate in an inverted V shape, and the length of the connecting plate is less than the length of the plate groove. Connecting parts are also provided on the outer sides of the two side plate grooves, and adjacent connecting parts are offset from each other. The connecting parts on the outer sides of the two side plate grooves are respectively connected to the first copper column electrode and the second copper column electrode through copper sheets.

[0006] A further improvement of the evaporation tank for electroplating generation of iridescent films of the utility model is that the support cushion block includes two groups, and long strip-shaped grooves are provided on the upper end surfaces of the support cushion blocks. The grooves on the two support cushion blocks are respectively used to support and clamp the lower ends of the two side plate grooves.

[0007] A further improvement of the evaporation tank for electroplating generation of iridescent films of the utility model is that there are two second copper column electrodes, which are arranged at intervals.

[0008] A further improvement of the evaporation tank for electroplating generation of iridescent films of the utility model is that there are two groups of the first copper column electrode, two second copper column electrodes, and the molybdenum boat structure, which are arranged in the tank body.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] The molybdenum boat of the present utility model is set in a V shape for accommodating electroplating materials. While ensuring stable accommodation of the materials, it also ensures that the materials are in contact with the molybdenum boat uniformly, thereby ensuring the evaporation effect and efficiency after the electrode is energized; the molybdenum boat is supported stably by two groups of support pads. The length of the molybdenum boat can be increased by welding, and the two groups of support pads are adjusted in cooperation to ensure material saving in support. BRIEF DESCRIPTION OF THE DRAWINGS
