Abstract
The utility model discloses a kind of portable preheating device, comprise frame, preheating cabinet, two shifting sledges and double-acting cylinder, the described shifting sledge level that front and back are moved towards respectively is placed in medial extremity and the outboard end of described frame, the medial extremity of described preheating cabinet and outboard end are slidably connected on corresponding described shifting sledge respectively, the top of described preheating cabinet is equiped with hot blast motor, in described preheating cabinet, inside and outside the below of described hot blast motor, both sides are provided with pcb board localization tool, described double-acting cylinder is installed in described frame, move forward and backward along described shifting sledge for driving described preheating cabinet.The double-acting cylinder of this portable preheating device drives preheating cabinet to while welding post movement, hot blast motor is toward blowing hot-air on pcb board, ensure that pcb board does not fall temperature or minuses temperature before welding location completes, thus ensure that the activity of scaling powder is to obtain best scolding tin effect.
Description
Technical field
The utility model relates to mechanical field, particularly relates to a kind of portable preheating device.
Background technology
The welding procedure of PCBA is all scaling powder coating, and then preheating is to excite the activity of scaling powder, then goes up tin.With reference to the welding process requirement of wave-soldering, the temperature required for different scaling powders is also different, but the temperature that when all scaling powders all require that pcb board starts to weld, the temperature in plate face compares preheating section decline more few better.Now commercially selection weldering both domestic and external all adopts fixing preheating zone, and after preheating completes, pcb board goes to welding section (for 400 long slabs), and the time is about 3--5 second, and temperature declines and is about 40 degree.The activity of the scaling powder in such welding during tin does not reach best.
Utility model content
The purpose of this utility model is that providing a kind of ensures that pcb board does not fall temperature or minuses the portable preheating device of temperature before welding has been located, thus ensures that the activity of scaling powder is to obtain best scolding tin effect.
To achieve these goals, the technical solution of the utility model is: provide a kind of portable preheating device, comprise frame, preheating cabinet, two shifting sledges and double-acting cylinder, the described shifting sledge level that front and back are moved towards respectively is placed in medial extremity and the outboard end of described frame, the medial extremity of described preheating cabinet and outboard end are slidably connected on corresponding described shifting sledge respectively, the top of described preheating cabinet is equiped with hot blast motor, in described preheating cabinet, inside and outside the below of described hot blast motor, both sides are provided with pcb board localization tool, described double-acting cylinder is installed in described frame, move forward and backward along described shifting sledge for driving described preheating cabinet.
Described preheating cabinet is also provided with far-infrared ceramic heating board immediately below described pcb board localization tool.
Compared with prior art, the double-acting cylinder of the portable preheating device of the utility model drives preheating cabinet to while welding post movement, hot blast motor is toward blowing hot-air on pcb board, ensure that pcb board does not fall temperature or minuses temperature before welding location completes, thus ensure that the activity of scaling powder is to obtain best scolding tin effect.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model portable preheating device angle.
Fig. 2 is the structure chart of portable another angle of preheating device of the utility model.
Detailed description of the invention
With reference to figure 1 and Fig. 2, the portable preheating device 100 of the utility model comprises frame 10, preheating cabinet 20, two shifting sledge 30 and double-acting cylinder 40.
Described shifting sledge 30 level that front and back are moved towards respectively is placed in medial extremity and the outboard end of described frame 10.The medial extremity of described preheating cabinet 20 and outboard end are slidably connected on corresponding described shifting sledge 30 respectively.The top of described preheating cabinet 20 to be equiped with in hot blast motor 21, described preheating cabinet 20 both sides inside and outside the below of described hot blast motor 21 and to be provided with pcb board localization tool 22.Described double-acting cylinder 40 is installed in described frame 10, moves forward and backward along described shifting sledge 30 for driving described preheating cabinet 20.Described preheating cabinet 20 is also provided with far-infrared ceramic heating board 23 immediately below described pcb board localization tool 22.
When the portable preheating device 100 of the utility model uses, pcb board 200 is clamped on described pcb board localization tool 22, double-acting cylinder 40 drives preheating cabinet 20 to while welding post movement, hot blast motor 20 is toward blowing hot-air on pcb board 200, ensure that pcb board 200 does not fall temperature or minuses temperature before welding location completes, thus ensure that the activity of scaling powder is to obtain best scolding tin effect.
More than in conjunction with most preferred embodiment, the utility model is described, but the utility model is not limited to the embodiment of above announcement, and amendment that the various essence according to the present embodiment carries out, equivalent combinations should be contained.
