The utility model belongs to the technical field of PCB carrier plate production, and particularly relates to an ultra-clean dryer.

Description

Ultra-clean dryer

Technical Field

The utility model relates to an ultra-clean dryer, and belongs to the technical field of PCB carrier plate production.

Background

The PCB carrier, also called a printed wiring board, is an important electronic component, and is a support for electronic components. When the carrier plate is produced, a plurality of processes are needed to dry the product, and large water drops on the surface of the carrier plate can be primarily blown off by a drying air knife before entering a dryer, and then the product enters the dryer for drying.

At present, the principle of a dryer commonly used in industry is that air is compressed into an air inlet pipe through a fan, because the fan has higher power, the volume compression temperature is increased after the air enters the air inlet pipe through the work of the fan, so that an additional heating device is not required to be equipped, and then the air is directly blown through an air outlet for drying.

However, when the existing dryer is used for drying, dust, foreign matters and the like are blown to the surface of a product together with air, so that the yield of the product is reduced; in addition, the air pipe of the dryer is generally a nonmetallic hose, so that the air pipe is easy to damage after long-term pressure bearing, more importantly, dust and foreign matters are generated when air flows at a high speed after the air pipe is aged for several years, and the yield of products is further reduced; further, in general, a driving system of a conveying roller in a dryer is a gear type transmission, and friction foreign matter is generated, so that dust is generated in the dryer. The superposition of the above conditions greatly reduces the product yield.

Disclosure of Invention

According to the defects in the prior art, the technical problems to be solved by the utility model are as follows: an ultra-clean dryer is provided to improve the yield and qualification rate of the products produced by the carrier plate.

The ultra-clean dryer comprises an equipment shell, wherein a carrier plate conveying device and a carrier plate drying device are arranged in the equipment shell, the carrier plate drying device comprises a fan, the fan is connected with an air outlet above the carrier plate conveying device through an air pipe, and air filters are arranged at the air outlet and the air inlet of the fan.

The utility model adopts a mode of blower and air filter, adds a filter at the air inlet and outlet, ensures that the dry air blown onto the substrate is clean air, avoids the influence of foreign matters, and ensures the yield of carrier production.

Preferably, the air outlet is provided with a HEPA efficient filter, and the air inlet of the fan is provided with a primary filter.

In the utility model, the carrier plate conveying device comprises a plurality of rollers which are arranged in parallel, and the main shaft rotates through the non-contact magnetic force wheel driving roller. The non-contact magnetic transmission is adopted, so that the generation of friction foreign matters is reduced, and the qualification rate of products is further improved.

Preferably, the air pipe is a stainless steel pipe, so that the air pipe is corrosion-resistant, high in strength and capable of reducing dust generation.

Compared with the prior art, the utility model has the following beneficial effects:

the utility model provides a novel clean dryer, which has more reasonable structural design, is additionally provided with an air filter, changes a transmission mode and changes the material of an air pipe, ensures that the drying air blown onto a substrate is clean air through the combined action of the air filter, the transmission mode and the air pipe, avoids the influence of foreign matters, ensures the yield of carrier plate production, and greatly improves the yield of products.

Detailed Description

The utility model will be further illustrated with reference to specific examples.

However, the description of the present utility model is merely an embodiment of a structural or even functional description, and the scope of the claims of the present utility model is not limited by the embodiments described herein.

For example, the embodiments may have various modifications and various forms, and it is to be understood that the scope of the claims of the present utility model includes equivalents capable of realizing the technical idea.

Also, since the objects or effects achieved by the present utility model do not mean that a specific embodiment should include all or only those effects, the scope of the right of the present utility model is not limited thereby.

As shown in fig. 1, the ultra-clean dryer according to this embodiment includes a device housing 1, and a carrier plate conveying device and a carrier plate drying device are disposed in the device housing 1.

The carrier plate conveying device comprises a plurality of rollers 6 which are arranged in parallel, and the main shaft 4 connected with the motor rotates through the non-contact magnetic force wheel 5 to drive the rollers 6, so that the generation of friction foreign matters is reduced.

The carrier plate drying device in this embodiment includes fan 11, and fan 11 passes through tuber pipe 10 to be connected carrier plate conveyer top tubaeform air outlet 9, and air outlet 9 department is equipped with high-efficient filter 8, and fan 11's air intake 13 department is equipped with primary filter 12. The duct 10 of the present embodiment employs stainless steel pipes.

During operation, the carrier plate 7 can blow the big water drop on the surface of the carrier plate 7 through the drying air knife before entering the dryer, and then enters the device through the inlet 2, and is transported through the rotating roller 6. Meanwhile, the volume compression temperature rises after air enters the air pipe 10 through the work of the fan 11, and then the carrier plate 7 on the roller 6 is directly blown through the air outlet 9 for drying. After drying, the carrier plate 7 is output from the outlet 3.

Of course, the foregoing is merely preferred embodiments of the present utility model and is not to be construed as limiting the scope of the embodiments of the present utility model. The present utility model is not limited to the above examples, and those skilled in the art will appreciate that the present utility model is capable of equally varying and improving within the spirit and scope of the present utility model.
