Description

PCB drying unit

Technical field

This utility model relates to the manufacture field of PCB, particularly relates to a kind of PCB drying unit.

Background technology

Pcb board is also called printed wiring board, is one of the vitals of electronics industry.Almost every kind of electronic equipment, little arrives Accutron, computer, arrive greatly computer, communication electronic device, and military issue weapons system, as long as there being the electronics unit devices such as integrated circuit Part, for the electric interconnection between them, will use printed board.In relatively large electronic product research process, most basic Success factor be the design of printed board, documentation and the manufacture of this product.The design of printed board and the direct shadow of workmanship Ring the quality to whole product and cost, even result in the success or failure of commercial competition.

In the production process of pcb board, relate to a lot of wet method processing technology, as circuit etching, rough surface process, Palm fibre, melanism etc., be required in time plate being carried out drying and processing after carrying out these process.Therefore, this type of making apparatus is all Being configured with drying section, the effect of drying section is to dry plate face, prevents plate face from aoxidizing.Because drying section itself belongs to metallic article, Built-in object is metal, glue goods, perishable during high temperature production, aging and fall bits；Secondly, drying section air channel is passed through Aerator enters, and equipment surrounding and the foreign body of equipment own counter can stick to pcb board face.

Utility model content

Based on this, it is necessary to for deficiency of the prior art, it is provided that a kind of PCB drying unit.

A kind of PCB drying unit, including for transmitting the transporter of pcb board, air knife component, aerator and warm-air pipe, Described air knife component includes air knife and lower air knife, and described windward cutter spacing is above transporter, and leeward cutter spacing is in transporter Lower section, described upper air knife, lower air knife be connected with aerator by warm-air pipe respectively, and the air inlet of described warm-air pipe also sets up Having defecator, described defecator filters the foreign body entered in warm-air pipe.

Further, described PCB drying unit also includes that Wind volume detector, described Wind volume detector are located at filtration dress The rear side put, the Wind volume detector detection size by the hot blast air quantity after defecator.

Further, described Wind volume detector is provided with siren, when Wind volume detector detects that air quantity is less than During setting value, described warning devices sends alarm.

Further, described defecator is filter cotton.

Compared with prior art, PCB drying unit of the present utility model is by arranging filtration dress at the air inlet of warm-air pipe Put the foreign body in air filtering, it is possible to effectively reduce graininess foreign substance pollution, save drying section service time, facilitate pcb board Cleaning maintenance, the most purged pan section can be prevented effectively from and be secondarily contaminated；Additionally, described Wind volume detector can Detection air quantity so that drying effect is more preferable, its reasonable in design, simple for production, it is greatly saved the cleaning cost of pcb board, Be conducive to promoting.

Accompanying drawing explanation

Fig. 1 is the structural representation of the PCB drying unit in this utility model.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.

As it is shown in figure 1, this utility model provides a kind of PCB drying unit, described PCB drying unit includes for transmitting The transporter 10 of pcb board, air knife component 20, aerator 30, warm-air pipe 40 and Wind volume detector (not shown), described air knife Assembly 20 includes the upper air knife 21 being positioned at above transporter 10 and is positioned at the lower air knife 22 below transporter 10, described windward Cutter 21, lower air knife 22 are connected with aerator 30 by warm-air pipe 40 respectively, and the air inlet of warm-air pipe 40 is provided with filtration dress Putting 50, described Wind volume detector by the hot blast air quantity after defecator 50 and sends alarm for detection.

Described upper air knife 21 and lower air knife 22 are arranged in pairs alternatively up and down, upper air knife 21 and lower air knife 22 with transmitted The vertical dimension of pcb board 60 can be adjusted according to actual process demand.In the present embodiment, described defecator 50 is efficient mistake Filter pulp, described defecator 50 can filter the foreign material in the air entered in warm-air pipe 40 and dust, with entering under cleaning high-temp Plate air.Described detection device is for detecting the air quantity by the hot blast after defecator 50, when air quantity is less than setting value, and institute State detection device and will send alarm, in access aperture, affect product quality to avoid dry film to dry not exclusively.

During use, when pcb board carries out drying operation by transporter, the hot blast in aerator 30 passes through warm-air pipe The defecator 50 of 40 air inlet, Wind volume detector detects by the air quantity after defecator 50, when air quantity is examined Survey device and detect when air quantity is less than setting value, send alarm, then need to add Wind Volume.Hot blast enters air knife group, and air knife group blows out Wind the dry film of pcb board is dried so that pcb board more cleans.

This utility model crosses the foreign body in air filtering by arranging defecator 50 at the air inlet of warm-air pipe, it is possible to effectively Reduce graininess foreign substance pollution, save drying section service time, facilitate the cleaning maintenance of pcb board, can be prevented effectively from and blow Inswept pan section is secondarily contaminated；Additionally, described Wind volume detector can detect air quantity so that drying effect is more preferable, Its reasonable in design, simple for production, it is greatly saved the cleaning cost of pcb board, is conducive to promoting.

Embodiment described above only have expressed a kind of embodiment of the present utility model, and it describes more concrete and detailed, But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, common for this area For technical staff, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these all belong to In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
