2. the interval transporting fixture is transported and is transported continuously
Fig. 2 illustrates the interval transport action transporting fixture 30 between the continuous transport action and descaling bath 230E and the electroplating bath 200 that transport fixture 30 in electroplating bath 200.Fig. 2 illustrates the fixture 30 that transports ahead shown in dotted line in three the transport fixtures 30 supported by fluctuating orbit 236 and has just been handed off to the state behind position shown in solid power supply rail 201 from fluctuating orbit 236.
In fig. 2, fluctuating orbit 236 can be lifted along lifting shaft 252 by the driving of lift motor 250.This fluctuating orbit 236 has can support four length transporting fixture 30, is that two or three transport fixtures 30 are supported in actual driving.Accordingly, as vacant space, have and support at least one space transporting fixture 30.
At fluctuating orbit 236 before the state of Fig. 2 rises, it is in spray groove 230D one and transports in fixture 30(Fig. 2 not shown) in the way of being supported, carry out feed motion by fluctuating orbit 236.So, it is equipped with three fluctuating orbits 236 transporting fixture 30 to rise.It is configured with top pusher 260 in lifting position.This top pusher 260 has three feedings on bar 262 and determines journey block 264.Bar 262 by the feed screw 268 that driven by feeding motor 266 and can forward-reverse.
On the other hand, each of three the transport fixtures 30 supported by fluctuating orbit 236 is fixed with the 1st driving sheet 320(also referring to Fig. 6).When fluctuating orbit 236 rises, the front of journey block 264 is determined in three the 1st three feedings driving sheet 320 to be arranged in top pusher 260.When making bar 262 advance afterwards, three feedings advanced together with bar 262 are determined journey block 264 and are promoted three the 1st and drive sheets 320, and three are transported fixtures 30 and only advance unit distance.So, the top transporting the fixture 30 upper direction electroplating bath 200 from descaling bath 230E ahead is moved.
Afterwards, fluctuating orbit 236 declines.So, transport fixture 30 ahead is arranged in electroplating bath 200 as shown in phantom in Figure 2.In order to cross the next door 237 between different treatment troughs, use fluctuating orbit 236 and top pusher 260, transport fixture 30 and intermittently transported.
Shown in the transport fixture 30(dotted line ahead being supported on fluctuating orbit 236) joined to power supply rail 201 from fluctuating orbit 236 by bottom pusher 270.Bottom pusher 270 has the feeding supported by bar 272 and determines journey block 274.On the other hand, transport fixture 30 have can determine the 2nd driving sheet 321(that journey block 274 abuts with feeding also referring to Fig. 6), the 2nd of the transport fixture 30 ahead being supported on fluctuating orbit 236 drives sheet 321 to be arranged in feeding to determine the front of journey block 274.When making bar 272 advance afterwards, the feeding advanced together with bar 272 is determined journey block 274 and is promoted the 2nd driving sheet 321, transports fixture 30 and only advances along arrow A direction unit distance.So, the top transporting the fixture 30 upper direction electroplating bath 200 from descaling bath 230E ahead is moved.Join to power supply rail 201 from fluctuating orbit 236.
Now, the sequential control by bar 272 workpiece 20 that the transport fixture 30 of the rear row advanced by bar 272 supports configures only separated by clearance G with low velocity continuous leading workpiece 20 transported on fixture 30 in transit on power supply rail 201 with being supported on.Clearance G is the narrowest more good, but needs to prevent the interference each other of the workpiece 20 of leading and rear row, is set to 10mm or size around as design load.If this is owing to clearance G is big, then electrolysis concentrates on the two ends of workpiece 20, and as so-called Os Canitis, the electroplating thickness at workpiece 20 two ends is thickening, it is impossible to enough guarantee the reason of inner evenness.
Hereinafter, with reference to Fig. 3 and Fig. 4, the action transporting fixture 30 in pre-treatment groove group 230 off and on is illustrated.In Fig. 3 and Fig. 4, as the interval transport action in Fig. 2, the only interval transport action in same groove uses bottom pusher 280,284,286 to implement with trapped orbit 232,234,235, in the case of being included in the interval transport action exceeding next door 237 between different grooves, top pusher 282 and fluctuating orbit 233 is used to implement interval transport action.Additionally, Fig. 4 is to be indicated as the figure after launching from cold water washing trough 230C to descaling bath 230E, but it is to replace trapped orbit and use the swing-around trajectory 131 of horizontal rotation or swing-around trajectory 132 to implement that interval in spray groove 230D is transported, swing-around trajectory 131(132) and the trapped orbit 234,235 before and after it between interval transport and implemented by bottom pusher 284,286.And, explanation being eliminated for the interval transport action in rear treating groove group 240, but as described above, is to use swing-around trajectory 141,142, trapped orbit 242,243 is implemented with not shown bottom pusher.

Both sides at workpiece 20, it is possible to the guide member transporting and guiding workpiece 20 is set, and blocks the blocking parts of the upper and lower end parts of workpiece 20.And then, it is possible to the height and position that the total length of workpiece 20 adjusts guide member and blocking parts matchingly.Owing to the upper and lower end parts of workpiece 20 is blocked by blocking parts, it is possible to prevent that electric field from concentrating on the upper and lower side of workpiece 20 and electroplating thickness is thickening.
4. transport fixture
Keep the transport fixture 30 of workpiece 20 as shown in figs.5 and 6, there is the portion that is directed to 300 guided by power supply rail 201, the linking part 330 extended towards free end horizontal direction from the base end part being directed to side, portion 300, and the maintaining part 340 being connected with the free end of linking part 330 and keeping workpiece 20 to be hang.
Here, to being directed to power supply rail 201 that portion 300 guides as shown in Figure 6, vertical section be have upper surface 201A, lower surface 201B, the 1st side 201C of electroplating bath 200 side and with the 1st side 201C to the rectangular section of the 2nd side 201D.It addition, the shape that the shape of power supply rail 201 transports the guide rail of fixture 30 (trapped orbit 232,234,235,242,243, fluctuating orbit 231,233,236,241 or swing-around trajectory 131,132,141,142) with interval beyond electroplating bath 200 is consistent.
It is directed to portion 300 have: the portion that is powered 301 contacted with the upper surface 201A of power supply rail 201, with at least one of the 1st side 201C Structure deformation of power supply rail 201, such as two the 1st rollers 302, with at least one of the 2nd side 201D Structure deformation of power supply rail 201, such as three the 2nd rollers 303, and the engagement part 304 engaged with continuous conveyer 400.So, the portion that is directed to 300 with the portion that is powered 301 contacted with the upper surface 201A of power supply rail 201 because of deadweight is guided by power supply rail 201 by two sides 201C, 201D ground the 1st of Structure deformation the, the 2nd roller 302,303 of clamping power supply rail 201.Engaging with continuous conveyer 400 owing to self being provided with in the portion that is directed to 300 guided by power supply rail 201 and make transport force act on the engagement part 304 in the portion of being directed to 300, transporting on power supply rail 201 swimmingly so being directed to portion 300.It is directed in portion 300 at this, is provided with the 1st, the 2nd above-mentioned driving sheet 320,321 as shown in Figure 6.
4.1. the 1st, the relation of the height and position of the 2nd roller
In the present embodiment, as it is shown in fig. 7, the 1st roller 302 is lower with the 2nd height and position H2 of the 2nd side 201D Structure deformation than the 2nd roller 303 with the 1st height and position H1 of the 1st side 201C Structure deformation.So, it is possible to reduce owing to being cantilever support state and effect the most all the time has the angle of inclination transporting fixture 30 of unidirectional moment M.Its reason is treated as, with when having moment M, moving to the direction leaving power supply rail 201 relative to the 2nd roller 303, and the 1st roller 302 is powered track 201 and pushes and the mobile backstop function of conduct.Fig. 8 with reference to signalization is explained.Fig. 8 illustrates effect on L font parts L1, L2 shown after being directed to portion 300 signal moment M, the tilt angle theta 1 when L font parts L1, L2 to tilt between the front end at the 1st side 201C and L font parts L1, L2 of power supply rail 201 with only forming space δ, θ 2.The L font parts L1 connected at relatively low height and position H1 and the 1st side 201C only tilts less angle, θ 1.On the other hand, the L font parts L2 connected at higher height and position H2 and the 1st side 201C as L font parts L2 only tilts bigger angle, θ 2.
The height and position H1 of the 1st roller 302 is the lowest more good, preferably the bottom Structure deformation with the 1st side 201C of power supply rail 201.About moment M, the height and position of the 2nd roller 303 is unimportant, but fastens being directed to the pass that portion 300 contacts with the upper surface 201A of power supply rail 201, the 2nd roller 303 is disposed in proximity to this position being directed to portion 300 relatively good at the aspect drawn materials.Therefore, preferably the 2nd roller 303 with the upper end Structure deformation of the 2nd side 201D of power supply rail 201.
As it is shown in fig. 7, linking part 330 has thickness T between upper surface 331 and lower surface 332 in vertical direction.Between the height and position H3 and the height and position H4 of lower surface of the upper surface 331 that the 2nd height and position H2 of the 2nd roller 303 is arranged in linking part 330.So, the 2nd side 201D Structure deformation of the 2nd roller 303 and power supply rail 201 is made, it is possible to reduce and result from the Moment of the mobile counteracting force (with reference to Fig. 7) acted on the 2nd roller 303 on linking part 330 by the 2nd height and position H2 in the range of the thickness T of linking part 330.Therefore, the action transporting fixture 30 is smooth and easy.
For the relation with the thickness T of linking part 330, it is possible to make below the height and position H4 of the lower surface 332 that the 1st height and position H1 of the 1st roller 302 is positioned at linking part 330 as shown in Figure 7.As it has been described above, this is due to the reason the lowest more good for height and position H1 of the 1st roller 302.
4.2. the 1st, the position relationship on path direction is transported in the circulation of the 2nd roller
Fig. 9 illustrates the position on the circulation carriage direction A being located at the roller transported on fixture 30.
Such as three the 2nd rollers 303 are respectively provided with one at the 1st centre position p4 being directed between transport position, the front p1 in portion 300, transport rear end side position p7, transport position, front p1 and transport rear end side position p7.And, such as two the 1st rollers 302 are respectively provided with one at the 2nd centre position p3, the 1st centre position p4 transported between position, front p1 and the 1st centre position p4 and the 3rd centre position p5 transported between the p7 of rear end side position.Alternatively, it is also possible to different from Fig. 9, three the 1st rollers 302 are arranged in position p1, p4, p7, two the 2nd rollers 303 are arranged in position p3, p5.
Figure 10 is the top view of the state representing the seam 102 adding up to a part for five the 1st, the 2nd rollers 302,303 to stride across between two articles of guide rails 101A, 101B forming transport path 100.Five the 1st, the 2nd rollers 302,303 are added up to be configured to overlook as zigzag.Here, the posture transporting fixture 30 is determined by three the 1st, the 2nd rollers 302,303 and some Structure deformation of guide rail 101A, 101B.When shown in Figure 10, determined the posture transporting fixture 30 by three the 1st, the 2nd rollers 302,303 and the guide rail 101A Structure deformation of the first rostral of carriage direction A.In other words, two the 1st, the 2nd rollers 302,303 of the rear end side of carriage direction A can suppress the posture to transporting fixture 30 to produce baneful influence with guide rail 201B Structure deformation.On the contrary, under the state before the state shown in Figure 10, determined the posture transporting fixture 30 by three the 1st, the 2nd rollers 302,303 and the guide rail 101B Structure deformation of the rear end side of carriage direction A.In this case, two the 1st, the 2nd rollers 302,303 of carriage direction A elder generation rostral and guide rail 101A Structure deformation can suppress transport fixture 30 is produced baneful influence.
Article two, guide rail 101A, 101B are not the most the most in a straight line.Therefore it is required that to suppress the deviation of adjacent guide rail 101A, 101B that the posture transporting fixture 300 is produced baneful influence.Can solve the problem that this problem in the present embodiment.
Particularly, if when the workpiece 20 kept by transport fixture 30 is advanced in a liquid, the posture of workpiece 20 is inclined to when overlooking intersect with carriage direction A, then workpiece 20 bears the resistance of liquid and bends, and can damage commodity value.Present embodiment can suppress the generation of this state of affairs.
It addition, in the present embodiment, stablize and smooth and easy owing to the 2nd roller 303 can make the transport of transport fixture 30 move as mentioned above, so equally spaced configuring most number in the range of the greatest length of circulation transport path A is three.On the other hand, owing to the 1st roller 302 prevents the inclination relative to the effect of moment M shown in Fig. 7 of the transport fixture 30, so the quantity even if less than the 2nd roller 303 also is able to assure its function.And can guarantee to transport the stable motion of fixture 30 by one the 1st roller 302 of each configuration between two the 2nd rollers 303.
4.3. the 3rd roller
As shown in Figure 6, the portion that is directed to 300 of transport fixture 30 can also have at least one of the lower surface 201B Structure deformation with power supply rail 201, such as two the 3rd rollers 305.With reference to Figure 11 (A) of side view and Figure 11 (B) of top view, the 3rd roller 305 is illustrated.And, Figure 12 (A) and Figure 12 (B) show retreating position and the Structure deformation position of the 3rd roller 305.
The upper surface 201A Structure deformation in the portion that is directed to 300 with power supply rail 201 owing to transporting fixture 30, simultaneously the 3rd roller 305 and the lower surface 201B Structure deformation of power supply rail 201, it is possible to prevent from changing relative to power supply rail about 201.Therefore, the walking transporting fixture 30 is more stable.And, it is possible to sandwich power supply rail 201 by being powered portion the 301 and the 3rd roller about 305.Therefore, the 3rd roller 305 has and is prevented from transporting the function that tilts because of the moment M shown in Fig. 7 of fixture 30.
Here, the transport fixture 30 of present embodiment is directed to portion 300 and contacts with four face 201A～201D on the vertical section of power supply rail 201.So, the operation trouble that fixture 30 is arranged on power supply rail 201 will be transported.
Therefore, the 3rd roller 305 is supported for moving to the 2nd position (Figure 11 (A) of the lower surface 201B of the 1st position (Figure 11 (A), the dotted line position of Figure 11 (B) and the position of Figure 12 (A)) of the lower surface 201B Structure deformation with power supply rail 201 or disengaging power supply rail 201.The solid line position of Figure 11 (B) and the position of Figure 12 (B)).So, when making the 3rd roller 305 keep out of the way Figure 11 (A), the solid line of Figure 11 (B) or 2 position shown in Figure 12 (A), it is possible to transport fixture 30 is arranged on power supply rail 201.Afterwards, by making the 3rd roller 305 proceed to Figure 11 (A), the dotted line of Figure 11 (B) or the 1st position shown in Figure 12 (B), the lower surface 201B Structure deformation of the 3rd roller 305 and power supply rail 201.
In the present embodiment, it is possible to have and the 3rd roller 305 is exerted a force and makes its force application part moved towards the 1st position, such as helical spring 306, and overcome the force of force application part 306 that the 3rd roller 305 is maintained at the backstop 307 of the 2nd position.Such as, the gripper shoe 308 being directed to portion 300 and support the 1st roller 302 is provided integrally with the supporting part 308A of the 3rd roller 305.The one end of the bolt axle 309 being fixed in the hole (not shown) being passed through on supporting part 308A.At the other end of bolt axle 309, it is fixed with backstop 307 by nut 310,311.Helical spring 306 as force application part is enclosed within bolt axle 309 and is arranged between the 3rd roller 305 and supporting part 308A.The metalwork of backstop 307 for example, L font.When shown in Figure 11 (A), the solid line of Figure 11 (B) and Figure 12 (A), abutted with supporting part 308A by the end of the backstop 307 as the metalwork of L font, make helical spring 306 compress, and make the 3rd roller 305 keep out of the way.If backstop 307 half-twist of the metalwork as L font, then the end as the backstop 307 of the metalwork of L font departs from supporting part 308A.So, it is possible to make helical spring 306 freely stretch, the 3rd roller 305 is made to advance as shown in Figure 11 (A), the dotted line of Figure 11 (B) and Figure 12 (B).
In the present embodiment, at least two the 3rd roller 305 can be located at the 2nd centre position p3 as shown in Figure 9 and transport the position p2 of front, and the 3rd centre position p5 transports the position p6 of rear end side.This is can to make the more stable reason of walking of transport fixture 30 owing to two the 3rd rollers 305 configure separated by a distance.And, compare the 3rd roller 305 being arranged in both end sides be easier to operate to backstop 307 near central authorities of the portion of being directed to 300.
It addition, as shown in Figure 12 (A), Figure 12 (B), the portion that is powered 301 being directed to portion 300 has vertical wall 301A, and has gripper shoe 301B being arranged on this vertical wall 301A, supporting the 1st roller 302.Gripper shoe 301B have with vertical wall 301A to standing piece 301C.This standing piece 301C is fixed on vertical wall 301A by bolt 301D.Now, it is possible to adjust the position of the nut 301E of the position of the horizontal direction determining standing piece 301C.So, gripper shoe 301B can adjust relative to being powered the position in the direction orthogonal with power supply rail 201, the portion 301.So, it is possible to adjust the horizontal level of the 1st roller 302.It is thus possible to and the 1st of power supply rail 201 the, the interval between the 1st, the 2nd roller 302,303 is adjusted to most preferably by thickness between the 2nd side 201C, 201D matchingly.
4.4. linking part
Transport the linking part 330 of fixture 30 as shown in Figure 6, the portion that is directed to 300 being separately from each other is linked together with maintaining part 340.Owing to transporting fixture 30, there is linking part 330, so as it is shown in figure 5, the power supply rail 201 that guides of the portion that is directed to 300 transporting fixture 30 being become and positions away from from the top of electroplating bath 200.So, will not drop in electroplating bath 200 being directed to produced dust time slip on power supply rail 201 in portion 300.
Linking part 330 is such as fixed with two mounting sheets 331,332.These two mounting sheets 331,332 are positioned on two chains 151,152 of the return transport path 150 shown in Fig. 1, transport fixture 30 along returning transport path 150 and return transport.
4.5. maintaining part
Maintaining part 340 has multiple, such as three clamping sections 341 of the upper pinch by workpiece 20 as shown in Figure 6.In order to keep the workpiece 20 of amplitude broad, as standard facility or alternatively, it is possible to arrange movable pinch portion 342 in the both sides of three clamping sections 341.Can slide movement matchingly with the width of workpiece 20 in movable pinch portion 342.
5. continuous conveyer and engagement part
Hereinafter, the continuous conveyer 400 shown in Fig. 1, transport fixture 30 and engagement part 304 are illustrated.Additionally, can be widely applicable for transporting fixture 30 about the description below relevant with continuous conveyer 400 and engagement part 304 and at least there is the guide part 300 guided by power supply rail 201, the linking part 330 extended towards free end horizontal direction from the base end part being directed to side, portion 300, and be connected with the free end of linking part 330, the structure of the maintaining part 340 that keeps workpiece 20 to be hang.I.e., if it is arbitrary for using the 1st～the 3rd following trapped orbit 303～305.
5.1. continuous conveyer
Continuous conveyer 400 shown in Fig. 1 is as shown in Figure 6, it is possible to have the chain 410 being continuously conveyed driving, and the multiple band tooth blocks 420 being fixed on chain 410.Conveyer can also be formed by the most toothed belt continuously, but when being used for the electroplating bath 200 of more than tens of rice (including this value) in intensity and flexure poor reliability on this point.Therefore, have employed chain 410 in the present embodiment.Wherein, chain 410 as described later, due to can not guarantee transport fixture 30 positional precision, so multiple band tooth blocks 420 are fixed on chain 410.
Figure 13 (A), Figure 13 (B) show chain 410 and band tooth block 420.Figure 13 (A) is front view, and Figure 13 (B) is rearview.Chain 410 possesses the multiple inner links 411 supporting two rollers 411B, 411B between two interior plates 411A, 411A respectively, and is clipped adjacent two inner links 411 and respectively by its multiple outer links 412 connected to each other by two outer panel 412A.Each of outer links 412 comprises the fixed part 412B of fixing multiple band tooth block 420, is formed with bolt hole 412C on fixed part 412B, and band tooth block 420 is bolted fixing.
Hereinafter, band tooth block 420 is illustrated.Band tooth block 420 such as by resin injection moulding, has multiple tooth 421 at upper surface as shown in Figure 13 (A).As shown in the Figure 14 as the B portion enlarged drawing of Figure 13 (A), tooth 421 arranges with spacing P1.When the tooth 421 of a spacing is such as defined as the 1st inclined-plane, end face, the 2nd inclined-plane and trough face, as shown in figure 14, each width W in the 1st inclined-plane, end face, the 2nd inclined-plane and trough face is the most equal, W=P1/4.
The shape that one band tooth block 420 e.g. line is symmetrical, the tooth 421 at two ends terminates with inclined-plane.Now, length BL of a band tooth block 420 becomes K × P1-P1/4 when setting the number of teeth as K.Such as, when K=19, P1=4mm, BL=75mm.In the present embodiment, as shown in Figure 13 (A), the adjacent space between two band tooth blocks 420 is set to P1/4, and this space is as the trough face function of two teeth 421 in the opposite end portion being in each piece 420.So, the tooth 421 being formed on the multiple band tooth blocks 420 being fixed on chain 410 also maintains certain spacing P1 in the straight line moving portion of chain 410 between block 420.
It addition, the arrangement pitches P2 of two roller 411B of the chain 410 shown in Figure 13 (B) is bigger (P2 > P1) than the arrangement pitches P1 of the tooth 421 on the band tooth block 420 shown in Figure 13 (A).So, owing to only can not guarantee to transport the positional precision of fixture 30 by chain 410, so the band tooth block 420 that will be formed with closely spaced tooth 421 is fixed on chain 410.
Spacing P1 of the tooth 421 with tooth block 420 to consider as shown in Figure 2 between two workpiece 20 adjacent in electroplating bath 200 design load interval (gap) G relation after determine.As it has been described above, this is owing to when clearance G is big, the electroplating thickness at workpiece 20 two ends is thickening, it is impossible to enough guarantee inner evenness, for the reason of the positional precision of the workpiece 20 in this electroplating bath 200 to be improved, the i.e. positional precision of transport fixture 30.
In order to improve transport fixture 30 positional precision, spacing P1 making tooth 421 is the smaller the better, but from the relation of the clearance G of workpiece 20 for, preferably P1 < G/2.Even if this is rearward to deviate a spacing due to leading transport fixture 30, the transport fixture 30 gone the most afterwards forwards deviates a spacing, is also G-2 × P1 > 0, and adjacent transports the reason that fixture 30 will not conflict each other.I.e., either leading or rear row, allows that transporting fixture 30 only has the position deviation of ± mono-spacing P1.From the viewpoint of guaranteeing the intensity of tooth 421, the lower limit preferably making spacing P1 is P1 >=G/3.In the present embodiment, G=10mm, P1=4mm, meet G/3≤< P1 < G/2.
5.2. engagement part
The engagement part 304 being arranged in two positions shown in Fig. 1 has the integer that N(N was more than 2 (including this value) being engaged on some the band tooth block 420 being fixed on chain 410) individual, such as four tine 304A1～304A4.
These four tine 304A1～304A4 are shown in Figure 15.In fig .15, two tines 304A1,304A2 are supported by the 1st axle 312A being fixed in the portion that is directed to 300 transporting fixture 30.Two other tine 304A3,304A4 are supported by the 2nd axle 312B being fixed in the portion that is directed to 300 transporting fixture 30 and can rotate.Upper and lower at tine 304A1,304A2, separate space be configured with the 1st, the 2nd pin 313A, 314A.Equally, upper and lower at tine 304A3,304A4, separate space be configured with the 1st, the 2nd pin 313B, 314B.
So, four tine 304A1～304A4 are when engaging with the tooth 421 being formed on band tooth block 420, it is possible to the scope of avoiding (the 1st, the 2nd pin between) in the crest portion and trough portion crossing tooth 421 moves up and down.These four tine 304A1～304A4 are when transporting fixture 30 and being moved with the speed feeding higher than the translational speed of chain 410 by the bottom pusher 270 shown in Fig. 2, and crest portion and the trough portion of crossing the tooth 421 being formed on band tooth block 420 advance.
And, at the forward stroke terminal location of the bottom pusher 270 shown in Fig. 2, to transport fixture 30 and be not subjected to the external force of pusher 270 from below, some in four tine 304A1～304A4 engages with the tooth 421 being formed on band tooth block 420.Thus transport fixture 30 afterwards and be transported by the driving force of chain 410.
In order to some making four tine 304A1～304A4 engages with the tooth 421 of band tooth block 420, as shown in figure 15, the engagement front position of four tine 304A1～304A4 is deviation.
Figure 15 illustrates some of four tine 304A1～304A4 and engages with the tooth 421 of band tooth block 420, and other three tines are the posture identical with the tine of engagement.In the present embodiment, the engagement front position of four tine 304A1～304A4 deviates P1/4 relative to before and after tooth 421 difference of band tooth block 420.Therefore, the engagement front position of two coaxial tines 304A1,304A2 is that tine 304A2 the most rearward deviates P1/4 relative to the tine 304A1 become ahead on carriage direction A.Equally, the engagement front position of coaxial two other tine 304A3,304A4 is that tine 304A4 the most rearward deviates P1/4 relative to the tine 304A3 become ahead on carriage direction A.
Being spaced in during the integer that S was more than 2 (including this value) of the engagement front position of tine 304A2,304A3 is set as S × P1+P1/4.So, the engagement front position of four tine 304A1～304A4 deviates P1/4 relative to before and after tooth 421 difference of band tooth block 420.
Here, imagination is only configured with a tine 304A1 on transport fixture 30, or it is configured with the comparative example of multiple tine 304A1 with the spacing of the integral multiple of space width P1.As it has been described above, at the forward stroke terminal location of the bottom pusher 207 shown in Fig. 2, transport fixture 30 and be not subjected to the moment of the external force of pusher 270 from below, there is the situation that tine 304A1 does not engages with tooth 421.In this case, in the period of maximum mobile spacing P1 of the band tooth block 420 of movement by chain 410, tine 304A1 engages with some tooth 421.Therefore, allow that bias is spacing P1.
In the present embodiment, forward stroke terminal location at the bottom pusher 207 shown in Fig. 2, transport fixture 30 and be not subjected to the moment of the external force of pusher 270 from below, in the case of tine 304A1 does not engages with tooth 421, as long as making by the chain 410 band tooth block 420 of movement only move P1/4 before engaging with some of four tine 304A1～304A4 being respectively offset from P1/4 spacing.Therefore, allow that bias is reduced to P1/4.
As it has been described above, meet P1 < in the case of G/2, the most leading or rear row, transport fixture 30 and only admit of ± the position of spacing P1 deviation.Wherein, transport the positional precision of fixture 30 and depend on discrete, the translational speed etc. of forward stroke and the installation dimension precision of various parts of the bottom pusher 270 shown in Fig. 2.Therefore, the launching position transporting fixture 30 that bottom pusher 270 realizes between various electroplanting devices is different, the position of engagement error of tine superposes with the error of the stop position of this transport fixture, it is necessary to guarantee the clearance G between the workpiece shown in Fig. 2.
In the present embodiment, by P1 < make tine under conditions of G/2 allows that bias is reduced to the integer that P1/N(N was more than 2 (including this value)), clearance G between workpiece shown in Fig. 2 is set within being always such as 10m and (includes this value), and the conflict between the workpiece 20 before and after preventing.
It addition, be described in detail present embodiment as mentioned above, but those skilled in the art is understood that and can carry out physically additional matter and the more shape changeable of effect without departing from the present invention.Therefore, this variation is also all contained in the scope of the present invention.Such as, in description or accompanying drawing, at least the term once together recorded from more broadly or synonym different terms can be replaced as its different term everywhere at description or accompanying drawing.And whole combinations of present embodiment and variation are also contained in the scope of the present invention.
