Production line for plastic back cover film coating

Abstract

The invention discloses a production line for plastic back cover film coating. The production line comprises a feeding area, a film coating area, a discharging area and a movable frame. A treatment box and a circulating frame are arranged in the film coating area. First transmission rails are arranged in the treatment box and the circulating frame, the treatment box and the circulating frame are arranged in parallel, and transferring frames are arranged in the feeding area and the discharging area. The movable frame is moved between the treatment box and the circulating frames through the transferring frames. An ion source is arranged in the position, on one side of the feeding area, of the treatment box, a cold pump is arranged outside, the cold pump is connected with the interior of thetreatment box in a communicating manner, and a molecular pump is arranged on the cold pump. The transferring frames are arranged on a transferring base, and lead screw transmission assemblies are arranged between the transferring base and the transferring frames. Second transmission rails are arranged in the transferring frames. According to the production line, a low-temperature film coating process can be achieved, the yield of subsequent film coating can be guaranteed, a circulating function is achieved, and the production efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of surface treatment, in particular to a production line for coating a plastic back cover. Background technique [0002] The back cover of the mobile phone is the outer shell of the back of the mobile phone, which is generally made of metal, glass and composite materials. Due to the poor texture of plastic materials, the use of metal and glass materials has become common in recent years. However, due to the advent of the 5G era, the fifth The signal frequency of the next generation communication is completely different from that of the fourth generation, and the requirements for materials are very high. Metal materials and glass materials cannot meet the requirements of use, so composite materials are widely used. [0003] Due to the change from the hard material of metal and glass to the soft material of plastic, the existing production line cannot meet the needs of use, and the problem of materials falling in the...

Problems solved by technology

[0002] The back cover of the mobile phone is the outer casing of the rear of the mobile phone, which is generally made of metal, glass and composite materials. Due to the poor texture of plastic materials, the use of metal materials and glass materials has become common in recent years. However, due to the advent of the 5G era, the fifth The signal frequency of the first-generation communication is completely different from that of the fourth-generation communication, and the requirements for materials are very high. Metal materials and glass materials cannot meet the requirements of use, so composite materials are widely used.

[0003] Due to the change from the hard material of metal and glass to the soft material of plastic, the existing production line cannot meet the needs of use. There are often problems with materials falling in the production line during the production process, which greatly affects production efficiency, and now There is equipment but no circulation, so that the brackets for fixing materials need to be manually transferred, which greatly affects production efficiency and is also prone to damage
