Drying equipment for circuit board blower

Abstract

The invention introduces drying equipment for a circuit board blower. The drying equipment for the circuit board blower comprises an air inlet, an air passageway, an air inlet filter, a heater, a circulation wind duct, a wind duct filter, a wind outlet, a drying room, a drying rack and a temperature controller, wherein the air inlet is provided with the air inlet filter, the drying room is connected with the circulation wind duct, and the wind duct filter and the heater are arranged in the middle of the circulation wind duct. The temperature controller comprises a case body, the temperature controller, temperature probes, an alternating current contactor and a power line, the number of the temperature probes is plurality, and the temperature controller is provided with a plurality of input ports and a plurality of output end switches. By means of the drying equipment for the circuit board blast, the air humidity and the impurity content in the drying room are enabled to be limited in a certain level, the evaporated impurity particles are filtered by the filter, and thereby the air cleanliness in the drying room is guaranteed, and the cleanliness of the circuit board is enabled to be improved. The temperature controller is capable of probing temperature of a plurality of interior points, big temperature fluctuation is avoided, and the energy-saving and efficient purposes are achieved.

Description

technical field [0001] The invention relates to a drying device, in particular to a circuit board blast drying device. Background technique [0002] In the production of electronic devices, it is often necessary to produce printed circuit boards. In the production process of circuit boards, the electroplating process is a commonly used process. The circuit boards taken out of the electroplating pool need to be removed from the electroplating solution and washed and dried before use. However, in the process of drying wet circuit boards, if the drying equipment or measures are improper, the surface of the circuit board will often be polluted and affect the cleanliness of the surface. The drying equipment can generally be an oven, but the oven often has problems such as uneven temperature, which not only causes energy waste, but also leads to product scrap when the ventilation is not smooth.

AI Technical Summary

Problems solved by technology

[0006] Traditional electric ovens and other places that need to control the temperature generally use air conditioners or exhaust fans to cool down; the air conditioners can realize temperature control through their own constant temperature system, but the exhaust fans do not have temperature sensing functions. It is impossible to realize the adjustment function when the temperature is high or lower than the actual requirement, so how to provide an energy-saving and precise temperature control device has become a difficult problem in front of people

Moreover, traditional temperature control equipment is equipped with a temperature control probe, but there is usually only one temperature control probe, which can only indicate the temperature of an area. Generally, if the temperature of this area changes, the heating method will follow. Adjustment, there are often defects such as uneven temperature, high and low
