Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit board drying equipment, in particular to a printed circuit board drying device. Background Art

[0002] During the manufacturing process of printed circuit boards, the circuit boards must be taken out of the electroplating tank first, and then the electroplating liquid must be removed and washed and dried before they can be used. Drying can dry the surface of the circuit board and prevent the circuit board from being corroded and damaged by contact with water vapor and carbon dioxide in the air; Patent No. CN202321659375.X discloses a printed circuit board drying device, which uses alternately arranged rollers and air outlets to allow the bottom surface of the circuit board to be fully and evenly heated when the circuit board is transported on a roll, and the bottom surface of the circuit board can be blown by hot air; however, since the circuit board will be exposed to hot air from the bottom during drying, and the circuit board does not have a good limiting structure, the circuit board is easily displaced by the hot air during the transportation and drying process, which easily causes the circuit board to move randomly during the drying process. To this end, we propose a printed circuit board drying device. Utility Model Content

[0008] Specifically, a spring located between the hydraulic rod and the plate seat is installed on the outer periphery of the shock absorbing cylinder.

[0009] By adopting the above technical solution, the spring can cooperate with the shock-absorbing cylinder to make the plate seat have a certain elasticity and improve the tightness of the contact between the guide wheel and the circuit board, so as to facilitate more stable transportation of the circuit board and drying thereof.

[0010] Specifically, the inner peripheral surface of the body is equipped with transverse pipes for guiding flow, and there are multiple groups of transverse pipes. A corrugated pipe is installed between the transverse pipes and the diversion pipes.

[0014] Specifically, the outer side wall surface of the machine body is equipped with a glass plate.

[0017] 1.
