Now, by the example referring to Fig. 2 description according to the work of the welder 1 of the embodiment.Fig. 2 is to show welding
The exemplary diagram of the work of device 1.In fig. 2 it is shown that the only a part of welder 1.
As shown in Fig. 2, utilizing 50 covering nozzles 15 of pallet on top surface with printing plate 100 and electronic building brick 102
Opening 15a in the state of, welder 1 execute printing plate and electronic building brick welding.
Pallet 50 has the through-hole 51 for supplying fusion welding 11.By through-hole 51, fusion welding 11 is fed into print
On brush board 100.In other words, pallet 50 covers entire printing plate 100, in addition to the part of welding to be subjected.
Further, since using the opening 15a of 50 covering nozzles 15 of pallet, therefore according to the welder of the embodiment 1
It can strongly push the fusion welding 11 being drawn up by pump 30 against pallet 50.
Stated differently, since being filled using the opening 15a of 50 covering nozzles 15 of pallet, therefore according to the welding of the embodiment
Setting 1 can inhibit the pneumatic transfer pressure reduction of fusion welding 11.
Therefore, though the through-hole 51 of pallet 50 be it is small, welder 1 can also supply fusion welding 11 via through-hole 51
Onto printing plate 100.
Further, since welding can be executed in the state of applying pressure, therefore even if through-hole 51 is small, welder
1 is also supplied to fusion welding 11 on printing plate 100.
Therefore, electronic building brick 102 can be densely mounted on printing plate 100, and can be realized electronic building brick 102 and exists
It is integrated on printing plate 100.
Printing plate 100 and electronic building brick 102 are mounted on the top surface of pallet 50.Printing plate 100 has connecting hole 101,
Be formed as extending between the front and back surfaces.Connecting hole 101 has the metal layer being formed on inner peripheral surface.Connecting hole 101
In metal layer be connected to the predetermined printed wiring on printing plate 100.
In addition, electronic building brick 102, which has, is formed as connecting pin at position corresponding with the connecting hole 101 of printing plate 100
The metal lead wire terminal (being not shown in the accompanying drawings) of son.The lead terminal of electronic building brick 102 is inserted into the connecting hole of printing plate 100
In 101, and the printing plate with electronic building brick is arranged on pallet 50 thereon.
In addition, welder 1 is connected to robot (being not shown in the accompanying drawings), and pallet 50 is arranged so that by robot
The opening 15a of pallet covering nozzles 15.
In addition, printing plate 100 and electronic building brick 102 are fixed to pallet by robot when welder 1 is executed and welded
50.Therefore, it is mobile that printing plate 100 and electronic building brick 102 when executing welding are able to suppress.
If completing welding, robot withdraws pallet 50, and will have printing plate 100 and electronic building brick on top surface
102 new pallet 50 is arranged so that the opening 15a of new pallet covering nozzles 15.
This moment, the control process that will be executed referring to Fig. 3 description by the control unit 4 of welder 1.Fig. 3 is to show
The time diagram of the control executed in welder 1.In addition, being examined by detection unit 3 based on pressure detecting pipe 2 of control unit 4
The air pressure that measures and the rotation speed for controlling motor 31.
For example it is assumed that shown in fig. 3 at the time of t2 at, pallet 50 is installed so that the pallet covers by robot
The opening 15a of lid nozzle 15.In other words, it is assumed that utilizing the opening 15a of 50 covering nozzles 15 of pallet at moment t2.
In this case, from moment t2, control unit 4 is gradually increased the rotation speed of motor 31.As a result, melting
The air pressure that liquid level of the solder 11 in nozzle 15 is gradually increasing, and is detected by detection unit 3 also rises.
If reaching the base pressure of t3 at the time of as shown in Fig. 3 by the air pressure that detection unit 3 detects
Power, then the rotation speed of motor 31 is kept for the predetermined time in that time by control unit 4.
Here, reference pressure is the predetermined optimum pressure for each printing plate 100, and reference pressure is for example
For the value of determination based on the test by the progress such as operating personnel.In other words, reference pressure be for each printing plate 100 and
Appropriate pneumatic transfer pressure of the speech for the fusion welding 11 of welding.
If the air pressure detected by detection unit 3 is lower than reference pressure, fusion welding 11 may not pass through
The through-hole 51 of pallet 50, and if air pressure is higher than reference pressure, fusion welding 11 is supplied too much by through-hole 51
To printing plate 100.As a result, the problem of such as bridging phenomenon (bridge phenomenon) occurs.
Control unit 4 increases the rotation speed of motor 31, until air pressure reaches reference pressure, and if air pressure
Power reaches reference pressure, then rotation speed is kept for the predetermined time by control unit.Therefore, it can be incited somebody to action via the through-hole 51 of pallet 50
Suitable fusion welding 11 is supplied to printing plate 100, and can be improved the precision of welding.
In addition, the predetermined time is such as the time by setting experiment.For example, if the predetermined time it is too short, on a small quantity
Fusion welding 11 be fed on printing plate 100.
In addition, if the predetermined time is too long, then since a large amount of fusion welding 11 is fed on printing plate 100,
The problem of can causing such as bridging phenomenon.
In addition, that is, from moment t4, control unit 4 is gradually reduced the rotation speed of motor 31 after the predetermined time.
As a result, liquid level of the fusion welding 11 in nozzle 15 gradually decreases, air pressure is also reduced.
Later, t5 at the time of when air pressure reaches separating pressure, control unit 4 is to robotic transfer to indicate machine
The indication signal that device people separates pallet 50 with the 15a that is open.
Here, separating pressure is when the liquid level of fusion welding 11 after liquid level starts to reduce is separated with pallet 50
Air pressure at moment, and to pass through the preset values such as experiment.
If robot receives the indication signal, robot separates pallet 50 with opening 15a, and it is viscous to execute excision
The bridge for being attached to the unnecessary solder of the lead of printing plate 100 cuts (bridge cutting) processing.
Meanwhile control unit 4 stops motor 31 at moment t5, and prepares to be arranged as under covering opening 15a
One pallet 50.Optionally, after moment t5, the rotation speed of motor 31 can be maintained at predetermined rotary speed by control unit 4,
To make fusion welding 11 recycle.
It is used to fusion welding 11 being pneumatically conveyed to nozzle 15 as described above, control unit 4 is based on air-pressure controlling
Motor 31 rotation speed.In other words, control unit 4 controls the rotation speed of motor 31 using only air pressure.
Therefore, welder 1 is not needed such as detecting fusion welding 11 in the sensor of the liquid level in nozzle 15.
Therefore, manufacturing cost can be reduced by the cost of sensor etc..
In addition, if amount variation of the fusion welding 11 in solder bath 12, then act on the melting of impeller 33 (referring to Fig. 1)
The weight of solder 11 depends on the amount of fusion welding 11 and changes.In other words, air pressure reaches the horse where reference pressure
Rotation speed up to 31 depends on the amount for the fusion welding 11 being contained in solder bath 12 etc. and changes.
Since the welder 1 according to the embodiment increases the rotation speed of motor 31, until air pressure reaches
Reference pressure, therefore fusion welding 11 can be supplied to printing plate 100 in the case where not considering the amount of fusion welding 11.
Further, since rotation speed of the welder 1 based on air-pressure controlling motor 31, therefore can be during welding
Detect the exception of the bad contact between the opening 15a of such as nozzle 15 and pallet 50.
Specifically, in the case where air pressure does not rise rising although the rotation speed of motor 31 and to the greatest extent
Under the rotation speed of pipe motor 31 is maintained at the speed of increase but the undiminished situation of air pressure, control unit 4 is examined
Survey the bad contact between opening 15a and pallet 50.
This moment, the carry out step that will describe to execute by the welder 1 according to the embodiment referring to Fig. 4.Fig. 4 is to show
The flow chart of the carry out step executed out by welder 1.In the state of using the opening 15a of 50 covering nozzles 15 of pallet
It executes and carries out step shown in Fig. 4.
As shown in Figure 4, firstly, control unit 4 makes the rotation speed of motor 31 increase (step S101).Then, it controls
Unit 4 determines whether the air pressure detected by detection unit 3 is equal to reference pressure (step S102).
In the case where determining that air pressure is equal to reference pressure ("Yes" in step S102), control unit 4 keeps horse
Up to 31 rotation speed (step S103).Meanwhile in the case where air pressure is also not up to reference pressure (in step S102
"No"), control unit 4 continues to execute the process of step S101.
Then, whether the determination of control unit 4 has been subjected to predetermined time (step after air pressure reaches reference pressure
S104).In the case where having been subjected to the predetermined time ("Yes" in step S104), control unit 4 makes the rotation speed of motor 31
Reduce (step S105).
Meanwhile in the case where also without the predetermined time ("No" in step S104), control unit 4 continues to execute step
The process of rapid S103.Then, control unit 4 determines whether air pressure is equal to separating pressure (step S106).
In the case where air pressure is equal to separating pressure ("Yes" in step S106), control unit 4 indicates robot
Pallet 50 is set to separate (step S107), and completion is handled.
Meanwhile determining that air pressure is also not up to (step S106 in the case where separating pressure during step S106
In "No"), control unit 4 continues to execute the process of step S105.
