Problems solved by technology

[0003] The prior art PCB board gluing device is usually equipped with a glue storage box, and the glue storage box is provided with a glue outlet connected to it. When the glue inside the glue storage box is used up, the whole device needs to be stopped, and the inside Glue application is carried out after replenishing glue. This setting interrupts the glue application work and cannot work continuously. Therefore, it is necessary to set up a glue application device for continuous glue supply for PCB boards to solve the above technical problems.

Abstract

The invention discloses a gluing device for continuous glue feeding of a PCB, and relates to the technical field of PCB production. The device comprises a main body frame, a glue outlet mechanism is arranged on the main body frame, a bearing seat is arranged below the glue outlet mechanism, the bottom of the bearing seat is mounted on a lifting cylinder, the lifting cylinder is fixedly mounted onthe main body frame, the glue outlet mechanism comprises a glue box and a supporting block slidably arranged on the main body frame, a piston sliding up and down is arranged in the glue box, and a one-way valve C and a one-way valve A communicating with each other are arranged on the upper portion of the piston. A one-way valve D and a one-way valve B communicating with each other are arranged onthe lower portion of the piston. The output end of the one-way valve C and the output end of the one-way valve D communicate with a first pipeline, the output end of the first pipeline is connected tothe input end of a glue nozzle, and the glue nozzle is fixedly installed at the bottom of the glue box. The input end of the one-way valve A and the input end of the one-way valve B communicate witha second pipeline, and the input end of the second pipeline is externally connected with glue. The gluing device is stable in glue discharge and can achieve continuous glue discharge.

Description

technical field [0001] The invention relates to the technical field of PCB board production, in particular to a gluing device for continuous gluing for PCB boards. Background technique [0002] PCB, the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. Silicone is a kind of one-component RTV silicone with good adhesion, high strength and no corrosion. Because of its excellent electrical insulation performance, sealing performance and aging resistance, it can be used for a long time in the range of -50°C to +250°C, so it is widely used in the process of bonding PCB boards. PCB boards have strict regulations on the bonding process. For example, the glue needs to be applied evenly, and the amount of glue used needs to be contr...
