Terminal dividing head 71 is configured to support pair of terminal 20,20 around and is undertaken driving by terminal conveyance motor 74 (Fig. 2) and rotate, and pair of terminal 20,20 is transported the both sides to the workpiece 19 supported by workpiece dividing head 11 of the side of being located thereon.

(6) explanation of Workpiece supply mechanism 21

With reference to Fig. 1, Fig. 6, Figure 11, Figure 12, Workpiece supply mechanism 21 is described.

Figure 11 is the E-E line cutaway view of Fig. 1, be the figure representing Workpiece supply mechanism 21, Figure 12 is represent that workpiece is transported to the vertical view of the state of grafting material coating mechanism 31, and Fig. 6 is the front view of workpiece overlapping plates 18.

As shown in figure 11, carried out the workpiece 19 after arranging as the workpiece feed appliance 23 of a part for Workpiece supply mechanism 21 in the carrying of X-direction level and made it enter grooving 11c.

Rotate based on workpiece dividing head 11 and enter into grooving 11c and the workpiece 19 being adsorbed on grooving is rotated by workpiece dividing head 11 and cuts out from the row arranged and transported, under the state that next grooving 11c is opposed with workpiece feed appliance 23, next workpiece 19 is supplied to this grooving 11c again.

The attractor 24 forming a part for Workpiece supply mechanism 21, from the workpiece 19 attracting to enter into from workpiece feed appliance 23 grooving 11c by opposition side, makes workpiece 19 reliably enter grooving 11c.

The discoid workpiece overlapping plates 18 of coincidence is installed at workpiece dividing head 11.

At workpiece dividing head 11, there is the main part 11a that formed with the external diameter roughly equal with the external diameter of workpiece overlapping plates 18 and give prominence to and the flange part 11b be made up of raised line at circumferencial direction continuous print in the mode expanding its external diameter from the periphery of main part 11a, at flange part 11b, the grooving 11c being inserted into workpiece 19 is formed in the mode extended to axis (X-direction).

As shown in figure 11, the thickness t (thickness of rotating shaft direction (X-direction)) forming the flange part 11b of the surrounding of workpiece dividing head 11 is formed shorter than the length of the longest limit L of workpiece 19, and is set to and inserts and be placed on the electrode 19a, 19 outstanding from the two ends of flange part 11b at workpiece 19 two ends on grooving 11c.

Particularly in order to prevent the hard solders such as scolding tin to flange part 11b attachment and adhere to again to workpiece 19, expect the thickness t of flange part 11b-0.4mm more than less of the L size of workpiece 19.

In addition, as shown in figure 12, the width H-shaped of the circumferencial direction of the grooving 11c formed around workpiece dividing head 11 becomes shorter than the length of the longest limit L of workpiece 19.

This is because when the longest edge L between electrode 19a, 19b creating workpiece 19 two ends is loaded such exception towards circumferencial direction, workpiece 19 can not be inserted into grooving 11c.

Next, with reference to Fig. 6, Figure 11, workpiece dividing head 11 and workpiece overlapping plates 18 are described.

As shown in figure 11, at workpiece dividing head 11, correspondingly with grooving 11c from workpiece overlapping plates 18 side form counterbore 11d with the end and the first cross-drilled hole 11e be communicated with counterbore 11d by grooving 11c with being formed with.

On the other hand, as shown in Fig. 6, Figure 11, be formed with the workpiece air groove 18a opposed with counterbore 11d at workpiece overlapping plates 18, and coupling (coupler) 18b be communicated with workpiece air groove 18a is installed.Because discoid workpiece dividing head 11 and workpiece overlapping plates 18 overlap, so workpiece air groove 18a is sealed by workpiece dividing head 11 to keep the mode in small gap (such as 0.05mm).If attracted air by coupling 18b from workpiece air groove 18a, then pass through the surrounding attraction air of the first cross-drilled hole 11e and counterbore 11d from workpiece dividing head 11 from grooving 11c, the workpiece 19 being inserted into grooving 11c around it is adsorbed and is bearing in workpiece dividing head 11 around.

Workpiece dividing head 11 is configured to as shown in the solid arrow of Fig. 1 to anticlockwise.Therefore, workpiece dividing head 11 does not come off to make workpiece 19, needs the qualified product from the Workpiece supply mechanism 21 of upper right to bottom right or waste product output mechanism 101,102 are adsorbed by workpiece 19 and are bearing in around it.

In order to realize this point, as shown in Figure 6, the workpiece air groove 18a of opposed with the counterbore 11d (Figure 11) of workpiece dividing head 11 workpiece overlapping plates 18 is formed to the position opposed with the qualified product of bottom right or waste product output mechanism 101,102 (Fig. 1) from the position opposed with needing the Workpiece supply mechanism 21 (Fig. 1) of the upper right of adsorbing workpiece 19.

And, with qualified product or waste product output mechanism 101,102 opposed positions, be formed independently on the contrary from coupling 18b to counterbore 11d (Figure 11) blow out air with workpiece air groove 18a, make discharge air groove 18c, 18d that the workpiece 19 being adsorbed in grooving 11c (Figure 11) departs from from grooving 11c.

In addition, in the present embodiment, showing workpiece air groove 18a is a groove, but also can be made up of multiple groove to the position opposed with qualified product or waste product output mechanism 101,102 (Fig. 1) from the position opposed with Workpiece supply mechanism 21.

(B) action of terminal coupling device 10

Next, the action of terminal coupling device 10 is described.

Below, for the action of terminal coupling device 10, be divided into the state of the coated grafting material in both sides of (1) workpiece 19, (2) support the state of pair of terminal 20 at terminal dividing head 71, (3) terminal dividing head 71 rotates and pair of terminal 20 is transported the state that state and (4) pair of terminal 20 to the position opposed with workpiece 19 engage with the two ends of workpiece 19 and be described.

(1) state of the coated grafting material in the both sides of workpiece 19

Figure 12 represents that workpiece 19 is transported to the vertical view of the state of grafting material coating mechanism 31, and Figure 13 is the vertical view corresponding with Figure 12 of the state representing the coated grafting material in the both sides of workpiece 19.

As use Figure 11 above describe, workpiece 19 arranges from workpiece feed appliance 23 and enters the grooving 11c of workpiece dividing head 11.

As shown in figure 12, by the rotation of workpiece dividing head 11 by the workpiece 19 in-position adjusting mechanism 51 transported.

A pair distributor 32,32 is configured to the rotation of a pair motor 42,42 (Fig. 3) by forming distributor travel mechanism 33, is separated from each other (Figure 12) or (Figure 13) close to each other in the rotating shaft direction (X-direction) of workpiece dividing head 11.

Using the assigned position of the central authorities of mutually opposing outlet 32a, the 32a of a pair distributor 32,32 when close to each other as workpiece 19, by the effect of a pair pressing component 52,53, adjust to become the assigned position on workpiece dividing head 11 to workpiece 19.

After workpiece 19 position is adjusted to assigned position, as shown in figure 12, pressing component 52,53 leaves from workpiece 19, with this state, workpiece dividing head 11 is rotated again.

Next, rotated by workpiece dividing head 11 and arrived also temporarily stopping between a pair distributor 32,32 in grafting material coating mechanism 31 by the workpiece 19 transported.

Next, as shown in figure 13, in grafting material coating mechanism 31, by making movable plate 39 move to X-direction by a pair motor 42,42 (Fig. 3), thus it is a pair distributor 32,32 close to each other, based on the compressed-air actuated air pressure supplied from flexible pipe 32b (Fig. 3), discharge the grafting material of the paste of ormal weight from outlet 32a, 32a of front end.Thus, the grafting material of the coated paste in the two ends of workpiece 19.

Then, by making movable plate 39 move round about in X-direction by a pair motor 42,42, thus as shown in figure 12, a pair distributor 32,32 is separated from each other and leaves from workpiece 19.Workpiece dividing head 11 is made again to rotate in this condition.

Here, because workpiece 19 to be positioned at the central authorities of outlet 32a, 32a opposite each other by position adjusting mechanism 51, so the grafting material of having discharged ormal weight from these outlets 32a, 32a is coated in the two ends of workpiece 19 equably.

In addition, making after a pair distributor 32,32 be separated from each other, workpiece dividing head 11 is rotated and makes outlet 32a, 32a away from workpiece 19, thus under can preventing the state remaining in outlet 32a, 32a in a part for coated grafting material, workpiece 19 is transported again.

Further, because workpiece 19 is transported in the mode of two ends towards the X-direction of level, even if so be out of shape because of deadweight at the grafting material being coated on its two ends, the degree of its distortion is also even in both sides.

Then, rotated by workpiece dividing head 11 and by the workpiece 19 that transports after have passed between the camera 61 (Fig. 1) that the state of the hard solder at the two ends being applied to workpiece 19 is checked, arrive and be provided with engaging mechanism 103 bottom.Camera 61 checks area and the position of coated hard solder by image, and confirms coated weight according to area.

Wherein, owing to applying grafting material for distributor 32 to workpiece 19, to carry out, so can stably carry out from the discharge of the grafting material of distributor 32 mode of being discharged grafting material by the workpiece 19 moved one by one continuously.

(2) terminal dividing head 71 supports the state of pair of terminal 20

Figure 14 is the G-G line cutaway view of Fig. 1, is represent the figure supporting the state of pair of terminal 20 at terminal dividing head 71, and Figure 15 is the F-F line cutaway view of Figure 14, is the figure of the suction hole 71k representing terminal dividing head 71.

The workpiece 19 being coated with grafting material at two ends is transported to bottom because workpiece dividing head 11 rotates.

On the other hand, the accumulation in terminal feed mechanism 79 in terminal feed appliance 80 (Fig. 1) terminal 20 by terminal feed appliance 80 with short leg 20b (Figure 10) for upside and mutually opposing state transported in couples.

As shown in figure 14, by the pair of terminal 20,20 that transports by the terminal support tool 89 of terminal lifting device 81 (Fig. 1) with short leg 20b for upside and mutually opposing state rise, be supported on the recess 71d of the bottom of terminal dividing head 71 by absorption.

Now, detect by terminal test transducer 97 (Fig. 9) position whether arriving terminal support tool 89, or whether pair of terminal 20,20 is adsorbed the surrounding bottom being supported on terminal dividing head 71.

Here, the formation of the terminal dividing head 71 for adsorbing supporting terminal 20 is described.

As shown in Figure 1 and Figure 2, terminal dividing head 71 is in the form of annular discs, is provided with the discoid terminal overlapping plates 77 overlapped with terminal dividing head 71 at terminal dividing head 71.

In addition, as shown in figure 14, around the main body panel 71a of terminal dividing head 71, the both sides of thickness direction of recess 71d that contact of terminal 20, be formed respectively towards central groove 71e, 71e of central authorities.Around main body panel 71a, be formed with the first through hole 71g these central grooves 71e, 71e are communicated with.

Leaning on the main body panel 71a of center side to be also formed with the second through hole 71h than the first through hole 71g, be also formed with the second cross-drilled hole 71j be communicated with the second through hole 71h by the first through hole 71g.Second cross-drilled hole 71j is formed in not opposed with terminal overlapping plates 77 side.

First through hole 71g is sealed by the first endless member 71b overlapped around main body panel 71a from terminal overlapping plates 77 side.First through hole 71g, the second through hole 71h and the second cross-drilled hole 71j are sealed by the second endless member 71c overlapped around main body panel 71a from its opposition side.Therefore, the second through hole 71h of terminal dividing head 71 and opening opposed with terminal overlapping plates 77.

On the other hand, be formed with the terminal air groove 77a opposed with the second through hole 71h at terminal overlapping plates 77, and the coupling 77b be communicated with terminal air groove 77a is installed.

Because discoid terminal dividing head 71 and terminal overlapping plates 77 overlap, so terminal air groove 77a is sealed by terminal dividing head 71 with keeping small gap (such as 0.05mm).Therefore, if attract air by coupling 77b from terminal air groove 77a, then as the dotted line arrows, the second through hole 71h, the second cross-drilled hole 71j, the first through hole 71g and central groove 71e, 71e surrounding's attraction air from terminal dividing head 71 is passed through from terminal air groove 77a.

Thus, terminal dividing head 71 is configured at its ambient absorption and supports the pair of terminal 20,20 that short leg 20b contacts with the recess 71d face be formed in around it.

Here, formed by first and second endless member 71b, 71c sealing the suction hole attracting terminal 20,20 by central groove 71e, 71e of being formed at the both sides of the thickness direction of main body panel 71a at terminal dividing head 71.

(3) terminal dividing head 71 rotates and makes pair of terminal 20 be transported to the state of the position opposed with workpiece 19

Figure 16 represents that terminal dividing head 71 rotates and makes pair of terminal 20 be transported to the cutaway view corresponding with Figure 14 of the state of the position opposed with workpiece 19.

Terminal dividing head 71 shown in Figure 14 rotates while maintenance supports the state of pair of terminal 20,20.

As shown in figure 16, pair of terminal 20,20 conveyance is extremely supported by workpiece dividing head 11 and is positioned at the below of the workpiece 19 of its underpart by terminal dividing head 71.

By motor 95, the ball-screw 94 in the elevating mechanism 90 shown in Fig. 5 is rotated and lobe plate 93 is moved to Y direction, thus the terminal dividing head 71 of pair of terminal 20,20 conveyance to the below of workpiece 19 is risen.Thus, as shown in figure 17, the pair of terminal 20,20 being bearing in the top of terminal dividing head 71 is positioned at the both sides of the workpiece 19 of the bottom being supported in workpiece dividing head 11.

As shown in figure 16, pair of terminal 20,20 is with short leg 20b inner side and contacting with the bottom faces of recess 71d (Figure 15) towards each other, and the long leg 20a state parallel with the mutually opposing opposed faces of first and second endless member 71b, 71c is kept.

Wherein, the gap d (gap of rotating shaft direction (X-direction)) of first shown in Figure 16 and second endless member 71b, 71c is formed as to insert workpiece 19 to keep the mode in small gap between opposed long leg 20a.

(4) state that engages with the two ends of workpiece 19 of pair of terminal 20

Figure 17 is the cutaway view corresponding with Figure 16 representing the state that pair of terminal 20 engages with the two ends of workpiece 19.

As shown in figure 17, workpiece 19 be inserted into pair of terminal 20,20 opposed long leg 20a between and static.

And, as shown in figure 17, by heater travel mechanism 105 (Fig. 4), the pair of terminal 20,20 being transported to the both sides of workpiece 19 is pressed into the both sides being coated with grafting material of workpiece 19 and heats by a pair heater 104,104 close to each other, makes two side engagement of pair of terminal 20,20 and workpiece 19.

Then, a pair heater 104,104 is made to be separated from each other and to depart from from pair of terminal 20,20, by elevating mechanism 90 (Fig. 5), terminal dividing head 71 is declined again, the pair of terminal 20,20 engaged with the two ends of workpiece 19 is departed from from terminal dividing head 71.

Then, pair of terminal 20,20 is bonded on the workpiece 19 of both sides to be supported on the state of workpiece dividing head 11 by absorption, is rotated and transported further by workpiece dividing head 11.

And, when reaching be located at the bottom right of workpiece dividing head 11 output mechanism 101,102 shown in Fig. 1, remove and attract and workpiece 19 is departed from, qualified product drop on form qualified product output mechanism 101 conveyer belt on and be discharged, waste product drop on form waste product output mechanism 102 conveyer belt on and be discharged.Wherein, the core be positioned at workpiece 19 is provided with the hole of air blast (ejection), can make the discharge timing of workpiece 19, stable posture.

Like this, pair of terminal 20,20 is pushed into electrode 19a, 19b of the both sides of the workpiece 19 being coated with grafting material by a pair heater 104,104 and is engaged.In this situation, significantly set the plus-pressure of of (about 40N) a pair heater 104,104 in advance, and with it for benchmark sets the plus-pressure of another heater 104.

In this process, the pair of terminal 20,20 being adsorbed in terminal dividing head 71 moves a little with the impact be subject to by the state of adsorbing based on the pressing from both sides of a pair heater 104,104, can make terminal stable posture.

And as described above, the workpiece 19 being bonded on both sides due to pair of terminal 20,20 is transported, so pair of terminal 20,20 departs from from terminal dividing head 71 subsequently further to adsorb the state being supported on workpiece dividing head 11.

Terminal dividing head 71 possesses to adsorb pair of terminal 20,20 the suction hole 71k (Figure 15) formed around terminal dividing head 71.Thus, the movement of pair of terminal 20,20 and the disengaging from terminal dividing head 71 can reliably be carried out.

Further, elevating mechanism 90 is configured to, by using cam mechanism, terminal dividing head 71 can be made to move back and forth between the second place shown in the primary importance shown in Figure 17 and Figure 16.

In terminal coupling device 10, be configured to rotate in vertical plane, so the horizontal area that workpiece dividing head 11 occupies significantly reduces at thickness direction owing to workpiece 19 to be bearing in the workpiece dividing head 11 also rotated around.

In addition, be configured to rotate in vertical plane owing to workpiece 19 to be bearing in the workpiece dividing head 11 also rotated around, so arrange the implement for carrying out the process for workpiece 19 around the vertical plane that can exist at workpiece dividing head 11.Thus, be present in workpiece dividing head compared with the existing product in horizontal plane, the overall proprietary area on the horizontal level of device comprising implement can be made significantly to reduce.

In addition, because workpiece dividing head 11 is by from attracting air to be adsorbed by workpiece 19 around and being bearing in around, so can not need in the past in order to the chuck required for holding workpieces.

In addition, due to by so adsorbing holding workpieces 19, the device in the past needed to make workpiece be held in chuck is not also needed, so the proprietary area on horizontal plane can be reduced further.

Further, due to by the two ends of the workpiece 19 of horizontal supporting coating paste grafting material, even if so the grafting material of paste because its deadweight and make change of shape, its distortion degree also even in both sides.

Therefore, and compared with the situation applying grafting material up and down of the workpiece of vertical support, due to the grafting material uniformity separately of the paste at the two ends being coated in workpiece 19 can be guaranteed, so can balancedly engage pair of terminal 20 in the both sides of workpiece 19.
