Problems solved by technology

[0002] During the assembly process of the membrane tact switch, it is necessary to use a membrane to fix the dome (metal shrapnel) of the switch on the switch base, and then stick the dot-shaped buttons on the membrane. This method of assembly is prone to sticking of the buttons. Serious defects such as tightness, deviation of the installation position of the button, and easy drop of the button during assembly cause the product to lose the conduction connection function, resulting in a high defect rate of the switch, and at the same time, the consistency of the product is poor, which affects the quality of the product; therefore, It is necessary to design an assembly machine for membrane tact switches to improve the production yield of membrane tact switches and improve the quality of membrane tact switches

Abstract

The invention discloses a film switch assembly machine and a film switch production process. The film switch assembly machine includes a machine which is equipped with a first material rail and a second material rail. The first material rail is used for conveying a film carrying material belt, and the second material rail is used for conveying a base material belt. The first material rail is equipped with a point-pasting device for pasting keys onto the film carrying material belt. The second material rail is equipped with a discharging device and a film pasting device. The discharging deviceis used for moving and placing spring pieces on corresponding bases of the base material belt. The film pasting device punches the film carrying material belt and the keys into patches and pasting thepatches onto the corresponding bases of the base material belt. The film carrying material belt includes a carrier belt and a film. The carrier belt is provided with a carrying area in the middle, and the carrying area is provided with a plurality of type holes distributed in a matrix. The film is glued to one side of the carrying area. The point-pasting device cuts a hard material belt into a plurality of dot-shaped keys and pastes the keys onto the film under the corresponding type holes. By fixing the keys above the spring pieces through the film, problems such as insecure adhesion and installation position deviation of keys are solved, the product yield is improved, and the benefits of enterprises are improved.

Description

technical field [0001] The invention relates to the technical field of production of miniature light-touch membrane switches, in particular to a membrane switch assembly machine and a membrane switch production process. Background technique [0002] During the assembly process of the membrane tact switch, it is necessary to use a membrane to fix the dome (metal shrapnel) of the switch on the switch base, and then stick the dot-shaped buttons on the membrane. This method of assembly is prone to sticking of the buttons. Serious defects such as tightness, deviation of the installation position of the button, and easy drop of the button during assembly cause the product to lose the conduction connection function, resulting in a high defect rate of the switch, and at the same time, the consistency of the product is poor, which affects the quality of the product; therefore, It is necessary to design an assembly machine of a membrane tact switch to improve the production yield of t...
