Pair of right and left movable member 55,55 can be by separating near driver train 60 along separating, closely be installed on each pillar part 52,52 with the direction (being vertical direction (left and right directions among Fig. 4) in this form of implementation) that directions X intersects.On each movable member 55, by being used to guarantee that the outstanding holding member 56,56 of (establishment) space S is equipped with a plurality of holding pieces 57,57 (with reference to Fig. 5, Fig. 6) in this form of implementation.
This separation is by the pair of right and left connecting rod mechanism 61 shown in Fig. 4 (comprising connecting rod 63) near driver train 60 and forms drive source drives hydraulic actuating cylinder 68 formations.
The structure of connecting rod mechanism 61 is, pars intermedia comprises by top rest pin 62 and is attached at top connecting rod (connecting rod) 63 on the pillar part 52 rotationally, one end 63A of this top connecting rod 63 is attached on the upper end of movable member 55 rotationally by connecting pin 63AP, and the other end 63B is attached on the driving hydraulic actuating cylinder 68 rotationally.
In addition,, be provided with radicle and be attached at rotationally on the support unit 52, and the other end 66A is attached at the below connecting rod 66 on the bottom of movable member 55 rotationally by connecting pin 66AP by below rest pin 63 in order to improve action stability.That is, connecting rod mechanism 61 carries out the action identical with the connecting rod mechanism of parallelogram.
So, in Fig. 4 the left side shown near in the state (clamp position), because if the driving hydraulic actuating cylinder (drive source) by the left side 68 pushes the other end 63B downwards, then top connecting rod 63 is to turn left in the center with top rest pin 62, so the movable member 55 that is attached on the end 63A is risen, and can in Fig. 4, move by left.That is, a plurality of holding pieces 57 are separated with workpiece W.In addition, below connecting rod 66 is driven in top connecting rod 63.
Therefore, as shown in Figure 5, if the driving hydraulic actuating cylinder (drive source) about making 68,68 then can make a plurality of holding pieces 57,57 on the movable member 55,55 about being installed in leave workpiece W (clamping releasing) simultaneously simultaneously to detaching direction (below) action.
That is, can take out from the workpiece W after between the holding piece 57,57 surface treatment being finished, or new (for handling) workpiece W is inserted between the holding piece 57,57.
On the other hand, in the released state in Fig. 4 shown in the right side (clamping disarm state), because if the other end 63B is lifted upward by the driving hydraulic actuating cylinder (drive source) 68 on right side, then top connecting rod 63 is to turn left in the center with top rest pin 62, so the movable member 55 that is attached on the end 63A is descended, and can move by the left in Fig. 4.That is, can make a plurality of holding pieces 57 near workpiece W.In this case, below connecting rod 66 also is driven in top connecting rod 63.
Therefore, as shown in Figure 6, because if the driving hydraulic actuating cylinder (drive source) about making 68,68 moves to direction of closing (top) simultaneously, then can be by 57,57 workpiece of clamping (approaching) the simultaneously W of a plurality of holding pieces on the movable member about being installed in 55,55, even if so workpiece W is descended, it is immersed among the liquid Q in the surface treatment groove 10, can prevents that also this workpiece W from bending.
Like this, each holding piece 57 is to protrude in the state of movable member 55 by outstanding holding member 56 and installing under the state that separation on the above-below direction sets.Therefore, strong to the comformability of the size (size of above-below direction) of tabular thing (face), can guarantee the surperficial grade of tabular thing (face) well.
And, even can not be by bottom (or part of tabular thing (face) (position between the holding piece 57,57 of the above-below direction)) bending of the tabular thing (face) of holding piece 57 clampings, because curve can be housed in the space S of establishing between outstanding outstanding holding member 56 and the movable member 55, so can prevent to be attached on the movable member 55 between this curve.
In addition, each holding piece 57 is to the elongate of transporting the extension of (X) direction, and the while is with the upstream side position height of directions X, and the low inclination attitude in position, downstream is installed on the movable member 55.
So, even supposing to take place can not be by the bottom bending of the tabular thing (face) of holding piece 57 clampings, and this curve is on a certain holding piece 57, thereafter make tabular thing (face) when directions X moves, this curve automatically leaves upward from bevelled holding piece 57 downwards.In other words, not can along with tabular thing (face) to moving of directions X and with stronger power nip (riding).That is, can guarantee more successfully to transport tabular thing (face).
In the surface processing device of this form of implementation, drop at the dipping shown in Fig. 1 groove 10A top portion above, make the workpiece W decline of hanging the posture maintenance with vertical by lifting mechanism 30, make before it is impregnated in the liquid in this surface treatment groove 10, separate to drive and vertically to hang separation that posture keeps mechanism 50, make movable member 55,55 be released state shown in Figure 5 near driver train 60.
Between this movable member 55,55, maintain the suspension 40 that loads and keep by lifting mechanism 30 by force-input device (omitting among the figure) with the state shown in Fig. 3 left side.On suspension 40, hang posture and maintain workpiece W with vertical.
At this, separate near driver train 60 near driving, make movable member 55,55 approaching mutually as illustrated in fig. 6.That is, can be by cooresponding a plurality of holding pieces 57 from its two sides holding workpiece W.That is, the free motion that can limit workpiece W also can be kept the vertical posture of hanging for certain.
After this, make lifting mechanism 30 and 70 synchronized operations of up-and-down movement device, suspension 40 is descended with cantilever section 32, and framework 51 and elevator 71 (cantilever section 72) are moved downwards together.It is upper and lower relation state transitions shown in to the right of the state shown in the left side from Fig. 3.This is interpreted as and can be designed to make framework 51 liftings (up and down) by lifting mechanism 30 as described above.
At this moment, though move with higher speed among the liquid Q of thin workpiece W in dipping drops into groove 10A, but keep the vertical posture of hanging of mechanism 50 and keep function by the vertical posture of hanging, the bending shown in the long and two-short dash line among for example Fig. 9 that workpiece W produces because of liquid resistance can not take place.Therefore, owing to can reliably, stably be immersed in the interior liquid of surface treatment groove 10A, interfere so can prevent workpiece W and groove inside components (for example liquid heating component).
Behind dipping, transport between the workpiece W to directions X to beginning, separate to drive and separate near driver train 60, each movable member 55,55 is separated as illustrated in fig. 5.That is, make cooresponding a plurality of holding piece 57 leave workpiece W, remove clamping from its two sides.Tolerable workpiece W free motion.
Afterwards, make conveyer 20 actions, make suspension 40 only transport (moving ahead) spacing to directions X.At this moment, the non-maintaining part 44 of suspension 40 moves to directions X from the maintaining part 32A of lifting mechanism 30 1 sides.
Therefore, make lifting mechanism 30 and 70 synchronized operations of up-and-down movement device, cantilever section 32 is risen, framework 51 and elevator 71 (cantilever section 72) are moved upward together.It is upper and lower relation state transitions shown in to the left of the state shown in the right side from Fig. 3.
So, make conveyer 20 action, can to directions X one spacing one spacing transport suspension 40, and can be at surface treatment groove (acid ungrease treatment groove ... 10A) acid ungrease treatment is carried out on the two sides of workpiece W.Transportation speed is compared low with the descending speed in the dipping, remain on by anchor clamps 45 under the state on the suspension 40 simultaneously on top and on the directions X under the state of the direction traction workpiece W of at first anchor clamps 45, workpiece W can bending or warpage.
This workpiece is transported to the terminal part of next treatment trough 10 always, and by the down maneuver of lifting mechanism 30, the spacing of conveyer 20 is transported the vertical motion of action and lifting mechanism 30 and mentioned to the top of this treatment trough 10 herein.Afterwards, drop into groove 10B by not shown for example connecting mechanism to dipping and go up handing-over.
Like this, in dipping input groove (electrolytic copper plating treatment trough) 10B, carry out and the identical dipping of dipping input groove 10A.In this groove, be provided with and transport guiding mechanism 80, but, transport between the guide 81,81 (82,82) so can successfully import it because workpiece is to be kept function and kept and vertically hang posture by the vertical vertical posture of hanging of hanging that posture keeps mechanism 50.
And, owing to limited the free motion of workpiece W in transit during transporting guiding mechanism 80, thus can with and groove between the electrode that sets of both sides the interval, to be that pole spacing keeps certain, can stably carry out electrolysis (plating) processing.Promptly can produce high-quality PC board reliably, efficiently, increase substantially yield rate.
