Problems solved by technology

The polymerization process of Parylene monomer needs to be completed in a deposition chamber close to vacuum, which limits the application range of Parylene, that is, the size of the parts to be processed cannot exceed the volume of the deposition chamber. Due to the power of the vacuum pump, the deposition chamber The volume is not too large, usually around 70-100L
This makes it impossible for traditional coating devices to perform continuous surface processing on hundreds of meters or even thousands of meters of silicone rubber cables

Abstract

The invention discloses a continuous coating device for a coating layer on a surface of a cable and a method thereof. The coating device comprises a vacuum chamber, a pre-extracting chamber, a unwinding device and a winding device, wherein the pre-extracting chamber consists of upstream and downstream pre-extracting chambers at the upstream and downstream of the vacuum chamber; a cable inlet is formed at the front end of the upstream pre-extracting chamber near the unwinding device; a cable outlet is formed at the back end of the downstream pre-extracting chamber near the winding device; when the coating device is operated, a cable to be coated is released out by the unwinding device, and is leaded in the pre-extracting chamber and the vacuum chamber through the cable inlet and an opening in a baffle plate; when the cable is positioned in the vacuum chamber, a coating layer material is polymerized on the surface of the cable to form a coating layer; and the cable with a formed film is leaded out from the vacuum chamber and the pre-extracting chamber through the opening and the cable outlet, and is accommodated by the winding device. The continuous coating device enables the Parylene material coating to be changed from the intermittent single-furnace deposition to the continuous deposition, so that the coating efficiency is largely improved.

Description

technical field [0001] The invention relates to a coating device, in particular to a continuous coating device for the surface coating of a silicone cable. Background technique [0002] In modern industry, silicone rubber has a wide range of applications. It can be processed into pipes, sheets, films and special-shaped components according to needs, making many model products and industrial supporting products. Silicone tube is a linear polymer elastomer containing silicon-oxygen bonds, so it has high thermal stability, excellent resistance to ozone aging, oxygen aging, light aging and weather aging, as well as excellent electrical insulation properties, anti-aging properties. Mold performance and high breathability. Silicone rubber cables are suitable for power transmission lines for fixed laying or connecting cables for mobile electrical appliances with AC rated voltage of 0.6 / 1KV and below. It has convenient radiation, stable electrical performance in high temperature (...
