PCB tunnel drying device

Abstract

The invention discloses a PCB tunnel drying device. The PCB tunnel drying device comprises a base, a first electric conveying belt, a second electric conveying belt, a turnover mechanism, a feeding mechanism, a tunnel drying box, a first electric gate, an infrared grating, a cooling device and a second electric gate plate. The first electric conveying belt is arranged on the front side of the topend of the inner side of the base in the front-back direction. The second electric conveying belt is arranged on the rear side of the top end of the inner side of the base in the front-back direction.The turnover mechanism is arranged in an inner cavity of the base and located on the inner side of the first electric conveying belt and the inner side of the second electric conveying belt. The feeding mechanism is arranged on the front side of the base. According to the PCB tunnel drying device, integrated operation of feeding, drying and cooling of PCBs can be achieved, manual operation itemsof workers and transfer time between different devices are reduced, automatic overturning of the circuit boards during tunnel drying can be achieved, the workers do not need to manually turn over thecircuit boards for secondary drying, the drying period is shortened, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of PCB, in particular to a tunnel drying device for a PCB circuit board. Background technique [0002] Printed circuit board, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring. And assembly errors, improve the automation level and production labor rate, according to the number of layers of circuit boards can be divided into single-panel, double-panel, four-layer board, six-layer board and other multi-layer circuit boards, because printed circuit boards are not general terminal products , so the definition of the name is slightly confusing. For example, the motherboard used in personal computers is called the main board instead of the circuit board directly. Although there are circuit boards ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of PCB circuit board tunnel drying device, to at least solve the problem that the PCB circuit boards in the prior art mostly use a tunnel drying box for drying, because the tunnel drying box can only dry the PCB circuit board once. Drying on one side requires staff to manually turn over for secondary drying. The drying cycle is longer and requires staff to manually feed materials intermittently. The operation is more troublesome.
