Description

A kind of printed circuit board (PCB) drying device

Technical field

The present invention relates to a kind of dryer, especially refer to a kind of drying device of use in printed circuit board.

Background technology

Printed circuit board (PCB); Be that required circuit layout is printed on the multilayer plate body, again multi-layer sheet be compounded to form the circuit plate body, must the plate face coating last layer of this plate body be contained the printing ink of solvent then; And the interior oven dry of the dryer that is positioned over special use; Make the solvent evaporates in the ink lay on the plate body, to reach dry purpose

Existing traditional circuit board dryer is made up of blowing device, hot air apparatus and transport; Transport mainly is that circuit board is sent to dehydration and the oven dry of carrying out circuit board in blowing device and the hot air apparatus; Described blowing device mainly is to utilize air blast that the air communication in the machine is crossed Strong Wind Knife to derive the dehydrating function of realization circuit board under the effect of Strong Wind Knife; Described hot air apparatus is to utilize air blast that air-flow is derived, and along with the heat effect of storage heater, makes the air-flow of derivation be the hot blast state, and hot blast is forced to dry to the circuit board of importing on the transport through the effect of hot blast air knife; The complex structure of existing printed circuit board (PCB) drying device, the dehydration and the drying effect of circuit board are relatively poor, and Strong Wind Knife can't in the light of actual conditions regulate the size of air-out, thereby are difficult to meet people's instructions for use.

Summary of the invention

In order to overcome the deficiency of prior art, it is a kind of simple in structure that the present invention provides, the printed circuit board (PCB) drying device that result of use is good.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of printed circuit board (PCB) drying device, it comprises body, is provided with blowing device, hot air apparatus and transport in the body; Described transport is the upper and lower carrying roller that is arranged on the body; The front end of transport is provided with blowing device. and described blowing device comprises air blast, and air blast is connected with upper and lower Strong Wind Knife through airduct, and the air outlet on the Strong Wind Knife is on the gap between the upper and lower carrying roller; The rear end of transport is provided with hot air apparatus; Described hot air apparatus comprises air blast, and air blast is connected with upper and lower hot blast air knife through airduct and through heater, and the air outlet on the hot blast air knife is on the gap between the upper and lower carrying roller;

As the improvement of technique scheme, two pairs of Strong Wind Knifes about described blowing device is provided with, every pair of Strong Wind Knife is connected with an air blast respectively;

As the further improvement of above-mentioned technology side a case, the air outlet place of said upper and lower Strong Wind Knife is provided with the adjusting bolt.

The invention has the beneficial effects as follows: printed circuit board (PCB) is put in asking of upper and lower carrying roller; Under the effect of upper and lower carrying roller; Printed circuit board (PCB) gets into hurricane drier, and at this moment, air blast is introduced extraneous fresh air in the upper and lower Strong Wind Knife through airduct; Because the air outlet on the Strong Wind Knife is on the gap between the upper and lower carrying roller, thereby effectively carry out air-dry to printed circuit board (PCB); When upper and lower carrying roller is delivered to drying chamber with printed circuit board (PCB); Air blast is introduced extraneous fresh air in the heater; The back of heating of accepting heater forms hot blast, and hot blast is passed on the hot blast air knife, because the air outlet on the hot blast air knife is on the gap between the upper and lower carrying roller; Thereby make that effectively the residual solvent that attaches on circuit board volatilizees rapidly, promoted the baking properties of printed circuit board (PCB) greatly.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the A-A cut-away view of Fig. 1;

Fig. 3 is the B-B cut-away view of Fig. 1.

The specific embodiment

With reference to Fig. 1, Fig. 2 and shown in Figure 3, a kind of printed circuit board (PCB) drying device, it comprises body 1; Be provided with blowing device 2, hot air apparatus 3 and transport 4 in the body 1; Described transport 4 is for to be arranged on the upper and

lower carrying roller

41,42 on the body 1, and the front end of transport 4 is provided with blowing device 2, and described blowing device 2 comprises air blast 21; Air blast 21 is connected with upper and lower Strong Wind Knife 22,23 through airduct 24; Air outlet on the Strong Wind Knife 22,23 is on upper and lower carrying roller 41, gap between 42, and the rear end of transport 4 is provided with hot air apparatus 3, and described hot air apparatus 3 comprises air blast 31; Air blast 31 is connected with upper and lower hot

blast air knife

34,35 through airduct 32 and through heater 33, and the air outlet on the hot

blast air knife

34,35 is on upper and lower carrying roller 41, gap between 42.

This product obtains good air-dry effect in order to make blowing device 2, two pairs of Strong Wind Knifes about described blowing device 2 is provided with, and every pair of Strong Wind Knife is connected with an air blast 21 respectively.

The operation principle of this product is: at first with the printed circuit board (PCB) of making be put in upper and lower carrying roller 41, between 42; Under the effect of upper and lower carrying

roller

41,42, printed circuit board (PCB) gets into hurricane drier, at this moment; Air blast 21 is introduced extraneous fresh air in the upper and lower Strong Wind Knife 22,23 through airduct 24; Because the air outlet on the Strong Wind Knife 22,23 is on upper and lower carrying roller 41, gap between 42, thus effectively printed circuit board (PCB) is carried out air-dry, when upper and lower carrying

roller

41,42 is delivered to drying chamber with printed circuit board (PCB); Air blast 31 is introduced extraneous fresh air in the heater 33; The back of heating of accepting heater 33 forms hot blast, and hot blast is passed on the hot

blast air knife

34,35, and the air outlet on the hot

blast air knife

34,35 is on upper and lower carrying roller 41, gap between 42; Thereby make that effectively the residual solvent that attaches on circuit board volatilizees rapidly, promoted the baking properties of printed circuit board (PCB) greatly.

The present invention is for the ease of regulating the air-out size of Strong Wind Knife, and the air outlet place of said upper and lower Strong Wind Knife 22,23 is provided with and regulates bolt 5, according to the situation that reality is used, and the degree of tightness that can regulate bolt 5, thus realization changes the size of air outlet.

In sum, the dryer that printed circuit board (PCB) provided by the present invention is special-purpose except that the internal structure novelty, effectively shortens the stoving time of printed circuit board (PCB), thereby can be widely used in the oven dry of printed circuit board (PCB).
