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 utility model provides, the printed circuit board (PCB) drying device that result of use is good.
The utility model solves the technical scheme that its technical problem adopted:
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 beneficial effect of the utility model is: 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 utility model is further specified
Fig. 1 is the structural representation of the utility model;
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.
