Description

Technical Field

[0001] The present application relates to the technical field of thermal conductive gasket processing equipment, and particularly to a surface treatment and glue pasting device for thermal conductive gaskets. Background Art

[0002] Thermal conductive gaskets are widely used in industries such as electronics, electrical, and communication, especially in heat conduction and sealing of devices such as chips, integrated circuits, and power modules. Due to their excellent thermal conductivity, thermal conductive gaskets can effectively dissipate heat and ensure the stable operation of devices. In the electrical industry, thermal conductive gaskets are used for sealing and heat conduction of high-voltage electrical appliances such as high-voltage switches, which can effectively ensure the stable operation of electrical equipment. In the communication industry, thermal conductive gaskets are used for sealing and heat dissipation of base station equipment, antenna equipment, etc., which can significantly improve the transmission efficiency and stability of communication equipment.

[0003] The glued thermal conductive gasket is a product with double-sided adhesive paper added to the thermal conductive gasket. Such products can firmly adhere to the surface of the equipment or components that need heat dissipation during use, ensuring the stability and heat conduction effect of the thermal conductive gasket.

[0004] Currently, the production of glued thermal conductive gaskets usually relies on manual glue brushing. That is, the operator first brushes glue on the surface of the thermal conductive gasket.
