Problems solved by technology

[0003] Waterproof breathable valves generally consist of a breathable valve shell, a breathable valve cover, and a breathable membrane. Most of them heat-melt the breathable membrane onto the breathable valve shell. The process is simple, but the breathable membrane is easily damaged during the production process, which affects the service life of the product.

Abstract

The invention discloses a production method and production facility of a waterproof breathable valve, and relates to the production of the waterproof breathable valves. According to the production method of the waterproof breathable valve, a breathable film is embedded into a breathable valve shell through the injection molding technology, the damage to the breathable film is low, and the problemthat the breathable film of the produced waterproof breathable valve falls off due to the environmental influence cannot exist. The production facility of the waterproof breather valve comprises a breathable film automatic stripping and positioning module, a breathable film and breather valve transferring module, a breathable valve cover assembling module and a breathable valve sealing ring assembling module. According to the production method and production facility of the waterproof breathable valve, the problems that the forming period is long due to the fact that the breathable film and abottom film are manually separated and then put into a mold, and the product yield is low due to the fact that the injection molding technology is unstable are solved. Meanwhile, the functions of breathable valve automatic detection, automatic accepted product recognition and screening and automatic assembly are fulfilled.

Description

technical field [0001] The invention relates to the field of automation, in particular to the production of a waterproof breathable valve. Background technique [0002] The waterproof, dustproof and breathable valve has dual functions of waterproof and breathable. It is usually mainly used for antenna systems, radio frequency and digital processing equipment in communication base station systems. Most communication equipment is installed in complex and changeable outdoor environments. It has adjustable The pressure difference generated by the temperature difference between the inside and outside of the equipment can dredge harmful gases, and it has a waterproof function to ensure that the electronic components inside the equipment are protected from damage caused by rain. [0003] Waterproof breathable valves generally consist of a breathable valve shell, a breathable valve cover, and a breathable membrane. Most of them heat-melt the breathable membrane onto the breathable v...
