Computer PCB heat dissipation spraying device

Abstract

The invention provides a computer PCB heat dissipation spraying device. The device comprises a base, an machine frame is arranged on the base, guide rails are arranged at the inner bottom of the machine frame, carrying locking mechanisms are arranged on the guide rail, the carrying locking mechanisms are arranged on the two sides of the machine frame; one side of the middle part of the machine frame is provided with a servo motor and a driving wheel, the front part of the servo motor is provided with a driving shaft, the driving shaft is arranged at the axial position of the driving wheel, theother side of the middle part of the rack is provided with a driven wheel, the driven wheel is installed on the other side of the middle part of the machine frame through a first installing shaft, arotating belt is wound between the driven wheel and the driving wheel; a liquid storage bin is arranged at the lower part of the rotary belt, the liquid storage bin is parallel to the longitudinal direction of the rotary belt, and a plurality of spray nozzles are arranged at the bottom of the liquid storage bin; the spray nozzles are arranged above the guide rail; a heat dissipation paste mixing tank is arranged at the top of the machine frame, and a lower liquid pipe is connected to the bottom of the heat dissipation paste mixing tank. According to the device, a layer of heat dissipation paste layer is formed on the surface of a computer PCB, so that the spraying efficiency is greatly improved.

Description

technical field [0001] The invention relates to a spraying device, in particular to a heat dissipation spraying device for a computer PCB board. Background technique [0002] The main working part of the spraying machine is a double-acting pneumatic-hydraulic booster pump, and the reversing mechanism is a special pilot-operated fully air-controlled air distribution reversing device. After entering the compressed air, when the piston moves to the upper or lower end of the cylinder, the upper pilot valve or the lower pilot valve will be activated, and the air flow will be controlled to instantly push the air distribution reversing device to change direction, so that the piston of the air motor will perform stable and continuous reciprocating motion . Because the piston is rigidly connected to the plunger in the paint plunger pump, and the area of ​​the piston is larger than that of the plunger. The inhaled paint is thus pressurized. The pressurized paint is transported to t...
