Among above-mentioned Fig. 1:
The specific embodiment
The utility model embodiment discloses a kind of selective spraying machine, and is simple in structure, workable, can save solder flux and reduce follow-up cleaning process.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is known and detailed description, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.See also Fig. 1, selective spraying machine embodiment comprises among the utility model embodiment:
Spraying parts 102 are used for by default spray pattern described pcb board spraying scaling powder;
Transport section comprises: transport guide rails 1011, transmission chain 1012 and the first motor 1013, and transmission chain 1012 is laid on above the transport guide rails 1011, and the first motor 1013 is used for driving transmission chain 1012;
The spraying parts comprise: shower nozzle 1021, driving-belt 1022 and the second motor 1023, driving-belt 1022 are used for driving shower nozzle 1021, the second motors 1023 and are used for driving driving-belt 1022.
Selective spraying machine in the present embodiment may further include:
Optoelectronic switch is installed in above the spraying parts, whether enters spraying area for detection of pcb board;
Magnetic valve is installed in above the shower nozzle, is used for the spray time of control shower nozzle.
For ease of understanding, the below is described with the process of a concrete application scenarios to each the parts co-ordination of selective spraying machine in the present embodiment:
In the present embodiment, pcb board places on the transmission chain 1012, the first motor 1013, can be a servomotor, drive transmission chain 1012, so that pcb board can move to the shower nozzle direction, when the optoelectronic switch on the shower nozzle 1021 detects pcb board and has entered spraying area, the spray pattern of checking this moment is full jet mould formula or some jet mould formula, and above-mentioned full jet mould formula is namely carried out whole plate spraying to pcb board, and some jet mould formula namely sprays the preset, when being full jet mould formula, magnetic valve is opened always, and the second motor 1023 can be synchronizing wheel, drive driving-belt 1022, can for the supporting Timing Belt of synchronizing wheel, driving-belt 1022 drives shower nozzles 1021,1021 pairs of pcb boards of shower nozzle spray entirely; When being some jet mould formula, shower nozzle 1021 moves to the first preset points according to default program, this moment, default time end is opened and continued to magnetic valve, shower nozzle 1021 carries out a spray, then shower nozzle moves to next preset points according to relative coordinate next preset is sprayed, above-mentionedly move to next preset points according to relative coordinate and can understand like this: see also Fig. 1, take spraying parts direction as Y-axis, the transport section direction is X-axis, the below intersection point of both intersections is initial point, the first preset is (0,3), the second preset is (5,6), suppose that it is (0 that the shower nozzle initial position is in initial point, 0) locates, shower nozzle 3 distance to the first preset points of can moving on the Y-axis then, then spray, after the spraying end of the first preset, seek the second preset according to the relative coordinate rule, above-mentioned relative coordinate rule is for to choose the difference of Y-axis coordinate as the movement value of shower nozzle, the coordinate difference of X-axis is as the movement value of pcb board, shower nozzle this moment mobile 5-3 on the Y-axis then, namely 2 relative distance gets final product, before spraying, shower nozzle needs to confirm whether pcb board has moved the distance of the coordinate difference of X-axis, if then this preset is sprayed, this moment, the second preset became the first preset, continued to seek the second preset and namely sprayed next preset, until all preset sprayings is complete.
Whether above-mentioned affirmation pcb board has moved the distance of the coordinate difference of X-axis can be understood like this, the programme-control pcb board is mobile first, and then the control shower nozzle moves and can realize, also can both move simultaneously, but shower nozzle can wait for that a rational time sprays again according to translational speed and the distance of pcb board, can guarantee that so also shower nozzle sprays the preset, concrete implementation is a variety of in addition, does not do herein restriction.
After finishing spraying, shower nozzle 1021 can continue to be parked in the original place or to move to initial position, if shower nozzle 1021 rests on the position of end point spray, when then spray next time, if full spray then can move to first an end, entirely spraying process, if the some spray, then directly move to the first preset according to relative coordinate, then carry out a spray process.
Alternatively, the angle of the plane that forms of the axis of orientation at the axis of orientation at described transport section 101 places and spraying parts 102 places and horizontal plane is 3 to 4 to spend in the above-described embodiments.
Alternatively, in the above-described embodiments transport guide rails is broad-adjustable transport guide rails.
Among the utility model embodiment, transport section 101 moves pcb board to shower nozzle 1021 directions, optoelectronic switch detects pcb board and whether is in spraying area, if then select spray pattern, when being chosen as full jet mould formula, 1021 pairs of pcb boards of shower nozzle carry out whole plate spraying, when being chosen as a some jet mould formula, shower nozzle 1021 sprays the preset by default program, like this just can select spray pattern according to the situation of the required coating of pcb board, then spray, when the solder joint of needs sprayings is a lot of, can selects full jet mould formula simple flow and improve automaticity, when only needing the several solder joint of spraying, can selected element jet mould formula save solder flux and reduce follow-up cleaning process.
Above a kind of selective spraying machine provided by the utility model is described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
