Advanced Glove Box Vacuum Coating Technology

Vacuum coating technology first appeared in the 1930s, industrial applications began to appear in the 1940s and 1950s, and large-scale industrial production began in the 1980s. It has been widely used in industries such as electronics, aerospace, packaging, decoration, and hot stamping. Vacuum coating refers to the deposition of a certain metal or metal compound on the surface of a material (usually a non-metallic material) in the form of a gas phase in a vacuum environment, which is a physical vapor deposition process. Because the coating is often a metal film, it is also called vacuum metallization. In a broad sense, vacuum coating also includes vacuum deposition of non-metallic functional films such as polymers on the surface of metal or non-metal materials. Among all the materials to be plated, plastic is the most common, followed by paper coating. Compared with metals, ceramics, wood and other materials, plastics have the advantages of sufficient sources, easy control of performance, and convenient processing. Therefore, a wide variety of plastics or other polymer materials are used as engineering decorative structural materials and are widely used in automobiles, home appliances, and daily use. Packaging, craft decoration and other industrial fields. However, most plastic materials have defects such as low surface hardness, insufficient appearance, and low wear resistance. For example, a very thin metal film is deposited on the surface of the plastic to give the plastic a bright metallic appearance. A suitable metal source is also It can greatly increase the wear resistance of the surface of the material, and greatly broaden the decoration and application scope of the plastic.

Vacuum coating equipment mainly refers to a type of coating that needs to be carried out under a relatively high degree of vacuum, including many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, etc. The main idea is divided into evaporation and sputtering.

Equipment for Preparing Coatings for Solar Cells

In order to improve the competitiveness of photovoltaic products, one of the most effective ways is to increase the conversion efficiency of solar cells. In addition to improving the conversion efficiency of the cell itself through various technical means, considerable progress has also been made in improving the light transmittance and weather resistance of its packaging material-photovoltaic glass. The current mainstream technical solution is to coat the surface of the photovoltaic glass with an anti-reflection film, that is, use the sol-gel method to coat one or more layers of thin-film materials on the surface of the photovoltaic glass to reduce the reflection in a specific band of the spectrum, thereby improving the photovoltaic glass transmittance. The methods of coating the glass surface include roll coating, spraying, and surface etching, among which roll coating is the most widely used because of its convenient implementation.

However, all current technical methods cannot solve the problem of uniformity of the coating film. During the spray coating process, the coating solution in the center of the spray gun is more enriched, causing mottling; the surface etching method is difficult to uniformize the surface composition of the embossed glass, resulting in inconsistent etching reaction speeds and uneven film thickness;

The coating machine mainly uses the characteristics of high bonding force between aluminum molecules and the plated material in a vacuum state, and is an equipment that guarantees the process of attaching the plated material to the coating. This equipment has high efficiency, high speed, stability and reliability. , High cost performance. Most of the existing vacuum coating machines use the drum coating method. The main drum in the cavity is set directly above the evaporation source. The main drum is easily contaminated during the operation. The main drum is surrounded by rollers, which is difficult to clean and accumulates the deposited aluminum for a long time. Film will reduce the surface finish of the main drum. Contamination and cleaning will damage the main drum, and eventually cause scratches on the coil, which will affect product quality. In addition, the drum coating method before the coil enters the main drum, it is not easy to fully develop This situation will lead to empty lines and wrinkles after evaporation, which not only affects product quality, but also causes material waste.

Vacuum Glove Box Evaporation Coating


 Vacuum glove box Vacuum evaporation glove box (referred to as vapor deposition for short) is a glove box technology that has developed early in PVD professional skills and is widely used in technology. Although sputter plating and ion plating developed later have advantages over vapor deposition in many aspects, vacuum transpiration professional skills still have many advantages, such as the relative simplicity of special equipment and processing technology, which can plate very pure The film layer, which can be prepared with a special structure and properties, is still a very important glove box professional skill nowadays. In recent years, because of the extensive application of electronic bombardment transpiration, high-frequency induction transpiration and laser transpiration in the professional skills of transpiration glove boxes, this professional skill has become more and more perfect.

  Place the film in the vacuum glove box and use the evaporation source to heat it to evaporate. When the average free path of the evaporated molecules is greater than the linear scale of the vacuum glove box, the vapor atoms and molecules escape from the surface of the evaporation source. Blocked by the impact of other molecules or atoms, it can directly reach the surface of the coated substrate. Because the substrate temperature is low, it will condense on it and form a film. In order to improve the adhesion of the evaporated molecules to the substrate, the substrate is subjected to Appropriate heating is required. In order to make the evaporation glove box run smoothly, it should have the vacuum conditions in the evaporation process and the evaporation conditions in the film production process.

  Vacuum conditions during evaporation: When the average free path of the vapor molecules in the vacuum glove box is greater than the distance between the evaporation source and the substrate (called the evaporation distance), sufficient vacuum conditions will be obtained. Therefore, it is necessary to increase the average free path of the remaining gas, thereby reducing the collision probability of the vapor molecules and the remaining gas molecules, and pumping the vacuum glove box into a high vacuum.


  The vacuum degree in the vacuum glove box process is not as high as possible, because when the vacuum in the vacuum glove box exceeds 10-6Pa, it is necessary to bake the vacuum system to achieve degassing. Because the degassing of baking will form the pollution of the substrate, the film can be produced under high vacuum of 10-5Pa without degassing by baking, and the quality of the film is not necessarily better than that of the film prepared under ultra high vacuum. Poor quality is worth noting. Therefore, in the vacuum transpiration glove box equipment, the vacuum degree selected in the glove box room should generally be higher than 10-2Pa and lower than 10-5Pa.

Vacuum Coating Series Glove Box Evaporation Machine

The sample platform of the vacuum evaporation system can only complete the evaporation and film formation of organic and metal sources, and can only make 4 samples at one time. Although the magnetron sputtering system and the homogeneous film-forming system can also be connected to the evaporation chamber through a transition chamber, such equipment cannot place the magnetron sputtering system inside the evaporation chamber, and the mechanical manufacturing is complicated and inefficient. In addition, most machines cannot prepare multiple samples at one time. After the evaporation of each batch of samples, the atmosphere of the evaporation chamber needs to be destroyed to reload the samples, and then re-evacuate. As a result, researchers need to spend longer experimental time to obtain the experimental environment and perform relatively complicated operating steps, and the samples prepared for each batch are also different, resulting in the consequences of production lag and reduced scientific research efficiency.



For this reason, in the prior art, the sample platform of the vacuum evaporation system can only complete the evaporation and film formation of organic and metal sources, and can only produce a small number of samples at one time, and the production efficiency is low. machine. This system is integrated by vacuum coating system and glove box system. It can complete thin film evaporation in a high vacuum evaporation chamber, and store and prepare samples in a high purity inert gas atmosphere in the glove box.
