At scaling powder apparatus for coating 1, preheating device 2 and scolder fluidic device 3, can utilize as previously mentioned carrying device 4 conveyance base material B(Fig. 4) and check Fig. 5 with fixture 5() (checking Fig. 9 with fixture 100()).

As shown in Figure 1, carrying device 4 possesses: move into conveyer 15, it is for fixture 5(Fig. 5 by base material B and for checking) move into scaling powder apparatus for coating 1; The 1st conveyance conveyer 16, it is for using fixture 5 at the interior conveyance base material of scaling powder apparatus for coating 1 B with checking; Transfer conveyer 17, it is for being handed over to preheating device 2 with fixture 5 from combustion adjuvant apparatus for coating 1 by base material B and inspection; And the 2nd conveyance conveyer 18, it is at preheating device 2 and the interior conveyance base material of scolder fluidic device 3 B with check with fixture 5.

Move into conveyer 15, the 1st conveyance conveyer 16 along continuous straight runs configurations, transfer conveyer 17 is configured to raise gradually towards conveyance direction with 1/2 gradient of described the 2nd conveyance conveyer 18.And, described the 1st conveyance conveyer 16, transfer conveyer 17 the spaced and parallel with regulation the opposed faces of the track that configures alongst across a plurality of circular-rolls that are interval with of regulation.And operator is supplied to base material B etc. to move on conveyer 15, and it is moved to the 1st conveyance conveyer 16.

As shown in Fig. 4 of the top view as carrying device 4 (a), for the 1st conveyance conveyer 16, chain roller 16a is driven rotation by not shown motor etc., thereby the 1st conveyance conveyer 16 carries out conveyance with constant speed to moving into base material B in scaling powder apparatus for coating 1 etc.In addition, transfer conveyer 17 also forms the structure with roller 17a identical with the 1st conveyance conveyer 16, and by the 2nd conveyance conveyer 18 by the conveyances such as base material B of taking out of from scaling powder apparatus for coating 1 to preheating device 2.

The 2nd conveyance conveyer 18 consists of a pair of conveyer, and is configured to respect to the horizontal plane towards conveyance direction, raise gradually, and this pair of conveyer is loopy moving respectively in the both sides in conveyance path, and possesses cross section and be the roughly bootstrap block 19 of L word shape.

A plurality of bootstrap blocks 19 are integrated on each conveyer, and as shown in Figure 4 (b), to base material, B supports.

That is, cross section is roughly each bootstrap block 19 of L word shape and has slot part at the middle body of inside terminal surface, and slot part proper alignment when by conveyance path is in alignment, thus, in the two sides in conveyance path, forms the guiding groove 20 extending along conveyance direction.Described guiding groove 20 can keep fixture 5(Fig. 5 for base material B and inspection described later) prominent muscle portion 23.And, when the drive member such as motor by not shown drive conveyer, the base material B etc. that is held in guiding groove 20 with constant speed by conveyance.

Fig. 5 is the top view of fixture 5 for the inspection used in scolder fluidic device, and Fig. 6 is the cutaway view along the A-A line of Fig. 5.This inspection with fixture 5 for to solder bath 8(Fig. 1) the jet state of scolder check, check with fixture 5 by scaffold 21, by 2 inspections of these scaffold 21 supportings, with plate 22(the 1st, checked with plate 22a, the 2nd and check and use plate 22b) and dipping confirm plate 22c formation.In addition, check with fixture 5 from the front side of conveyance direction, by the 1st determination part the 24, the 2nd determination part 25 and the 3rd determination part 26 these three regions, formed successively.

Fig. 7 (a) is the top view of scaffold 21, and Fig. 7 (b) is the cutaway view along the B-B line of Fig. 7 (a).This scaffold 21 is that the outstanding material of the heat resistances such as fiber-reinforced plastic is formed to the parts that rectangular shaped forms while overlooking.In the both sides of scaffold 21, be formed with respectively along its length the prominent muscle portion 23 of extending.Scaffold 21 is so that prominent muscle portion 23 is supported on the mode of the guiding groove 20 of moving into conveyer 15, the roller 16a of the 1st conveyance conveyer 16 and the bootstrap block 19 of the 2nd conveyance conveyer 18, by the driving of conveyer and with constant speed by conveyance.

As shown in Figure 6, scaffold 21 is formed with the 1st recess 27 from upper surface side in the 1st determination part 24, in the bottom surface of the 1st recess 27, is formed with rectangular opening 27a, is communicated with up and down thus.At the 1st recess 27, dispose the 1st inspection and use plate 22a, and by not shown a plurality of pressing tablet nip side edge.In the lower face side of scaffold 21, be formed with from the inner edge of rectangular opening 27a abducent inclined plane 27b gradually, and form that expansion forms dodge recess 27c.

In addition, as shown in Figure 6, scaffold 21 is adjacent to be formed with the 2nd recess 28a from the upper surface of scaffold 21 with described the 1st recess 27 in the 2nd determination part 25.At the 2nd recess 28a, dispose the 2nd inspection plate 22b, the same with plate 22a with described the 1st inspection, by not shown a plurality of pressing tablet nip side edge.In the bottom surface of the 2nd recess 28a, be formed with respectively the 1st peristome 29a at 3 positions and the 2nd peristome 30a at 5 positions.At the bottom surface side of scaffold 21, at the 2nd peristome 30a at 5 positions around, what be further formed with that expansion forms dodges recess 30c.

The 1st peristome 29a is the circular through hole equally spaced arranging at 3 positions of the width of the bottom surface of the 2nd recess 28a.The taper seat that the lower side of the 1st peristome 29a is expanded towards the lower surface of scaffold 21 gradually by internal diameter size forms.Thus, the scolder of ejaculation is guided to middle body by taper seat, and contacts with plate 22b with the 2nd inspection in the 1st peristome 29a.And, by checking and observe with the top of plate 22b from the 2nd, can judge the surface pressing of the scolder contacting with plate 22b with the 2nd inspection.

That is, in the large situation of surface pressing, color is denseer, and in the little situation of surface pressing, color is turned white, and therefore whether suitable in a glance if just can judge surface pressing.In addition, taper seat angle of inclination is with respect to the horizontal plane set as being difficult to produce the 1st of precipitation and scaling powder gas in the scolder in flowing into the 1st peristome 29a and sets value (for example, 35 degree).

And, making the 1st peristome 29a become circular through hole is the part that (as the length direction of the 2nd peristome 30a) is difficult to arrange jet surface pressure adjustment part for the part to owing to not welding (welding shielding portion), can confirm jet surface pressure state, jet state, impregnation state.But the internal diameter size of through hole forms with surface pressing rising full-size.

The 2nd peristome 30a extends along the length direction of scaffold 21, and at 5 positions of width, arrange overlook the slotted hole of shape in the form of a substantially rectangular.Four dihedrals of the 2nd peristome 30a become circular-arc.The lower side of the 2nd peristome 30a forms the conical surface of expanding laterally gradually towards the lower surface of scaffold 21.In the 2nd peristome 30a, it is circular-arc that four dihedrals become, if therefore observe flow regime herein, can judge the viscosity of scolder and the difference of hardness.

That is, if scolder approaches circular arc edge, can to judge viscosity low, if high away from judging viscosity.

In addition, the angle of the conical surface of the 2nd peristome 30a is for example preferably, to the viscosity of scolder and few the 2nd setting value (, 45 degree) of effect of surface tension.

As shown in Figure 6, scaffold 21 is formed with respectively the 3rd recess 28b identical shaped with the 2nd determination part 25, the 1st peristome 29b, the 2nd peristome 30b and dodges recess 30d in the 3rd determination part 26.At the 3rd recess 28b, dispose dipping and confirm plate 22c, the same with plate 22a with described the 1st inspection, by not shown a plurality of pressing tablet nip side edge.

In addition, as shown in Figure 6, the value of the surface pressing state of the scolder in the 1st peristome 29b and the 2nd peristome 30b through hole that the internal diameter size of opening part (measure hole internal diameter size) forms for the base material B that can roughly be reproduced in as welding object up.But because surface at base material exists the difference of the surface texture that is formed with Copper Foil etc., therefore the internal diameter size of the 1st peristome 29b preferably decides as follows.

That is,, if the internal diameter size of the 1st peristome 29b is less than certain value,, when scolder is invaded, can produce the capillary impact of scolder self.Therefore, be preferably set to the value that is not easy to be subject to so capillary impact.

In addition, if the internal diameter size of the 1st peristome 29b is greater than certain value, the disorder of jet surface pressure can directly have influence on scolder and the contact condition checking with plate 22, cannot carry out suitable inspection.Therefore, be preferably set to the value that is difficult to occur scolder disorder.

Check with plate 22(the 1st and check with plate 22a, the 2nd and check and use plate 22b) be can be disposed at described in each

determination part

24,25, overlook the parts of shape in the form of a substantially rectangular.And, to checking with plate 22, (for example use following material, TEMPAX(テ Application パッ Network ス)), this material has that scolder to penetrating and inspection contact with the lower surface of plate 22 and the pattern that forms can be from the light transmission of upper side Visual Confirmation and the heat resistance of not being out of shape because of the temperature of the scolder of this melting.And dipping confirms that the gauge of plate 22c is identical with the gauge of the base material B such as substrate that in fact weld.

In addition, check that position (highly) that the lower surface with plate 22 moves is consistent with the position (highly) that the lower surface of base material B as welding object moves.Therefore,, according to checking with fixture 5, can, under the identical condition of the situation of base material B being welded with reality, detect the jet state of scolder.

As shown in Figure 5, the 1st, checking and use plate 22a, is being on width with respect to checking by the vertical direction of the conveyance direction of fixture 5, is formed with respectively the 1st and measures line 31, the 2nd mensuration line 32 and datum line 33.

Here, the 1st mensuration line 31 and the 2nd is measured line 32 and is formed by dotted line, and datum line 33 is formed by solid line.

Whether datum line 33 is lines of the assay standard that aligns for the edge of the rear end side with scolder pattern (trailing edge), to utilize the 1st to measure line 31 and the 2nd and measure line 32 and check at the 1st front edge (leading edge) that checks the scolder pattern forming with plate 22a in tram.

The 1st mensuration line 31 is such lines: if the welding condition penetrating from the 1st spray nozzle part 12 is suitable,, when the trailing edge by checking with the 1st pattern that scolder that the lower surface with plate 22a contacts forms aligns with datum line 33, can expect that leading edge arrives the 1st mensuration line 31.When the trailing edge of the pattern being formed by scolder aligns with datum line 33, by leading edge and the 1st position relationship (error) of measuring line 31, confirmed.

In addition, the 2nd mensuration line 32 is such lines: if the welding condition penetrating from the 2nd spray nozzle part 14 is suitable,, when the trailing edge by checking with the 1st pattern that scolder that the lower surface with plate 22a contacts forms aligns with datum line 33, can expect that leading edge arrives the 2nd mensuration line 32.When the trailing edge of the pattern being formed by scolder aligns with datum line 33, by leading edge and the 2nd position relationship (error) of measuring line 32, confirmed.And, by observing the state (position and inclination) at the pattern edge that checks the global shape of the pattern forming with plate 22 and formed by scolder at datum line 33 places, can judge the jet state of scolder.
