For example, as shown in figure 13, the end of limit plate 72 and the 5th connecting shaft 54 is respectively positioned on the front side wall surface of support plate 3 Front, the second end 722 that limit plate 72 is fixed on the 5th connecting shaft 54 are directed away from support relative to the 5th connecting shaft 54 3 direction of plate tilts forward, when limit plate 72 and the 5th connecting shaft 54 are rotated counterclockwise with reclaiming plate 6, limit plate 72 it is close The first end 721 of the fourth connecting shaft 53 is connected on the first front side surface 321 of support plate 3, and counterclockwise to reclaiming plate 6 turns Dynamic angle is limited, when limit plate 72 and the 5th connecting shaft 54 are rotated clockwise with reclaiming plate 6, the 5th connecting shaft 54 Peripheral surface is connected on the second front side surface 322 of support plate 3, and the angle rotated clockwise to reclaiming plate 6 limits, That is, the front side wall surface of support plate 3 is located on limit plate 72 and the rotation path of the 5th connecting shaft 54, to realize to reclaiming plate 6 Rotational angle range play restriction effect.
Preferably, the front side wall surface of support plate is V-shaped, and the both sides of V-arrangement are respectively the first front side surface 321 and the second front side Surface 322.
The connection type of limit plate 72 and the fourth connecting shaft 53, the 5th connecting shaft 54, as shown in fig. 7, limit plate 72 towards One end end face of the fourth connecting shaft 53 forms the first arc gap, and one end end face towards the 5th connecting shaft 54 forms Two arc gap, the fourth connecting shaft 53 are embedded in the first arc gap, and the 5th connecting shaft 54 is embedded in the second arc gap, thus will limit Position plate 72 is connected between the fourth connecting shaft 53 and the 5th connecting shaft 54.
The open Tumble-plating device of this embodiment, when needing that workpiece is electroplated, workpiece is previously positioned at the first chamber In body 11, initial state, the bottom of reclaiming plate 6 is connected on the bottom of open ports 12, and reclaiming plate 6 is to the work in the first cavity 11 Part plays barrier effect, if a bottom edge (side that the dotted line of regular hexagon is stated in Figure 16) for hexagon plate is horizontally It is connected on the inner wall of the bottom of the first cavity 11 of roller band 1.
Rotating electric machine is opened, motor is rotated along positive (such as counterclockwise) rotate driving driving shaft 82, drives 1 edge of roller band It is rotated on the gear on the gear and driven axle 83 on driving shaft 82 in close ring counterclockwise;When roller band 1 rotates, roller band The inner circumferential wall face driving end plate 2 of 1 the first cavity 11 is rotated in the clockwise direction, and the outer 211 of end plate 2 is in rotation process In, the part gone in the first cavity 11 is embedded in always in sliding slot 111, the week of the part on end plate 2 other than outer 211 It is connected to always to outside wall surface on the inner circumferential wall face of the first cavity 11.
During rotation, along its rotation direction, end plate protrudes into the intracorporal peripheral surface of the first chamber and is connected to always end plate 2 On the inner surface of first cavity, since end plate 2 is in regular hexagon, rotary motion trace is not rounded, center of rotation and movement rail Mark constantly variation in, the end plate 2 of hexagon not only rotate movement, also in an inclined direction under reciprocally shake, hold The periphery wall of plate also changes constantly in face of the bearing height of the inner wall of the first cavity 11 of roller band 1, to drive rolling Cylinder, which is done, to be shaken.
For example, when a protrusion 21 (by taking the protrusion 21 in the circle A in Figure 16 as an example) for hexagon plate, protrusion 21 from Figure 16 the position a horizontally toward start turning, by when the position a is rotated clockwise to the position b in Figure 12, protrusion 21 End is constantly tilted towards Shangdi when being connected on the inner wall of 11 bottom of the first cavity, the h0 of the highest point of end plate 2 from starting Be increased to h1, the center of rotation of end plate 2 is increased to c1 from c0, end plate 2 to the bearing height of the first cavity 11 of roller band 1 not yet Disconnected ground is increasing;
When protrusion 21 is rotated clockwise to the position c in Figure 16 by the position b in Figure 16, protrusion 21 is vertically abutted When on the inner wall of 11 bottom of the first cavity, the center of rotation of end plate 2 changes to c2 by c1, and the highest point of end plate 2 is increased by h1 Height arrives h2, and end plate 2 also reaches highest point to the bearing height of the first cavity 11 at this time, so, the highest point position of end plate 2 is by h0 When changing to h2, end plate 2 drives roller band 1 and support plate 3 and arc bracket 73 to do the shake tilted upward;
As the protrusion 21 constantly continues to rotate clockwise, when protrusion 21 turns to figure by the position c in Figure 16 When the position d in 16, the center of rotation of end plate 2 changes to c3 from c2, and the highest point of end plate 2 is reduced to h3 by h2, this process, end Plate 2 drives roller band 1 to do shake diagonally downward;
As end plate 2 continues to rotate clockwise, when turning to the position e in Figure 16 by the position d in Figure 16, protrusion 21 Herein in horizontally toward, the center of rotation of end plate 2 changes to c4 by c3, and the highest point of end plate 2 is reduced to h4 by h3, at this point, C4 and c0 be in identical height, and h4 and h0 are in identical height, and the drive roller band 1 of end plate 2 does trembling diagonally downward Dynamic, so that a sideband for completing end plate 2, which moves roller band 1, realizes the process back and forth shaken, the protrusion 21 is from open ports later 12 are detached from the inner wall of the first cavity 11;With continuing to rotate for end plate 2, another side of hexagon is continued to repeat above-mentioned Dither process, to realize that end plate 2 drives roller band 1 in constantly periodically reciprocal shake;
In entire rotation process, since the center of rotation (the chain-dotted line trend in such as Figure 16) of end plate 2 becomes constantly Change, end plate 2 makes the end plate 2 in constantly variation (trend of the dotted line in such as Figure 16) to the extreme higher position that roller band 1 supports Drive support plate 3 and curved support frame do it is synchronous tilt upward or downward shake, accordingly the first connecting shaft of support plate 3 51 move up and down in the first long lumbar hole 41, and the second long lumbar hole 31 is obliquely shaken on driven axle 83, to be placed on Workpiece in one cavity 11 not only rotates with roller band 1, does and shakes also as roller band 1, and then workpiece is constantly turned over Dynamic, the contact relation between adjacent workpieces is broken, so that the surface of workpiece different angle can touch electroplate liquid, is improved The uniformity of plating, to complete the electroplating process of workpiece.
In the plating process, due to the protrusion 21 of end plate 2 and the tangent setting of the fourth connecting shaft 53, when protrusion 21 rotates To at the fourth connecting shaft 53, the frictional force under is applied to the fourth connecting shaft 53, reclaiming plate 6 rotates down, along with discharging The gravity of plate 6 itself, bottom are connected to the bottom of open ports 12, and the bottom of the 5th connecting shaft is connected to 3 lower part of support plate On the wall surface of front side.
On the contrary, rotating electric machine rotates backward driving roller band 1 rotationally clockwise, when needing discharging to drive end plate 2 It rotates counterclockwise, end plate 2 still will drive roller band 1 and tilt upward or downward reciprocal shake, when protrusion 21 rotates To at the fourth connecting shaft 53, upward frictional force is generated to the fourth connecting shaft 53, to drive the fourth connecting shaft 53 with reclaiming plate 6 It is rotated up counterclockwise, so that forming discharging gap between the bottom of reclaiming plate 6 and the bottom of open ports 12, workpiece turns counterclockwise It moves and skids off roller band from this discharging gap, when the one end for the close the fourth connecting shaft for turning to limit plate 72 is connected to support plate When on 3, reclaiming plate stops operating, and the angle being rotated up to reclaiming plate 6 limits.When protrusion 21 crosses the fourth connecting shaft After 53, the driving of zerofriction force, reclaiming plate 6 rotates down clockwise under self gravity, the state of starting is reset to, more Under the continuous driving of a protrusion 21 and the fourth connecting shaft 53, reclaiming plate 6 is back and forth being rotated up and clockwise downwards counterclockwise Rotation, to realize entire discharge process.
