Centrifugal PCB plate automatic drying device

Abstract

The invention discloses a centrifugal PCB plate automatic drying device which comprises a base, a drying barrel, a front door, a cover plate, a motor, a main shaft, wheel plates symmetrically arranged along the main shaft, limiting seats, heating tubes, air cylinders, a temperature sensor, a sliding seat, scaleplates and a controller. When in operation, the front door is manually opened, PCB plates to be processed are placed in the limiting seats, the front door is closed, and the controller controls the motor to drive the wheel plates to rotate at high speed through the main shaft, so that the PCB plates are driven to rotate at high speed, moisture attached in the surface and holes of the PCB plates are spin-dried, and wastewater is discharged through a water discharging connector; meanwhile, the heating tubes work until the temperature reaches the preset temperature of the temperature sensor, so that the temperature in the drying barrel keeps constant; the intervals of the wheel plates can be adjusted through cooperative use of the sliding seat and the scaleplates, so that the PCB plates with different height sizes can be adapted. The device is simple in structure, moisture in the surface and holes of the PCB plates are removed by adopting the high-speed centrifugal dewatering principle, energy consumption is greatly saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a drying device, in particular to a centrifugal automatic drying device for PCB boards. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is a printed circuit board, also known as a printed circuit board, is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. Double-sided, multi-layer and flexible, and still maintain their own development trends. Due to the continuous development towards high precision, high density and high reliability, the continuous reduction in size, cost reduction and performance improvement will make printed boards in the future In the development project of electronic equipment, it still maintains a strong vitality. The PCB board needs to be dried during the board making process. The existing drying equipment uses an air knife to blow high-pressure and high-temperature gas to the PCB board...
