And, dispose rotating driveshaft 5 on the top of grinding unit 4, be used for being delivered to grinding unit 4 from the rotary driving force that has omitted illustrated drive source.Rotating driveshaft 5 makes the eccentric rotation of gripper shoe (wherein, eccentric rotation is meant that gripper shoe keeps under the state of certain attitude, certain some rotation (so-called revolution) around the mass centre that departs from gripper shoe) via the eccentric rotating mechanism that is arranged in the grinding unit 4.
When the eccentric rotation of gripper shoe, through the rotary transfer machine (lamination rubber unit) that has used the lamination rubber components, abrasive sheet also rotates with gripper shoe is likewise eccentric.So, through can be unsteadily supported with respect to glass plate 3 and the abrasive sheet of eccentric rotation, the surface of glass plate 3 (machined surface) be ground.
Fig. 2 representes the plane of grinding unit 4.But in Fig. 2, omitted gripper shoe, be illustrated in the form that has disposed air spring 10 on the abrasive sheet 7 and constituted the lamination rubber unit 12 of rotary transfer machine as last price fixing.
As shown in Figure 2, on the abrasive sheet 7 of rectangle, along its long side direction, air spring 10 is configured to row with lamination rubber unit 12.And; Abrasive sheet 7 is under the state that keeps this attitude (its direction is laterally configuration longways in the drawings); Some rotation (revolution) beyond the mass centre of abrasive sheet 7, but for this transmission of torque is arrived abrasive sheet 7, lamination rubber unit 12 is towards two directions configurations of vertical and horizontal.
Fig. 3 representes the sectional view of the grinding unit 4 of the 3A-3A line in Fig. 2.But in Fig. 3, also shown the gripper shoe of in Fig. 2, having omitted 6.
As shown in Figure 3; Grinding unit 4 disposes air spring 10 and lamination rubber unit 12 between gripper shoe 6 and abrasive sheet 7; Pushing force during abrading glass plate 3 (grinding pressure) P1, P2 are applied to abrasive sheet 7 through air spring 10, and come the rotation driving torque of self-supporting slab 6 to be delivered to abrasive sheet 7 through lamination rubber unit 12.Air spring is the flexible fluid spring that has utilized air, has the effect of absorbed oscillation.In addition, also can use the fluid spring that has utilized the gas beyond the air.
And, at the lower surface (glass plate 3 one sides) of abrasive sheet 7 grinding pad of foamed polyurethane system for example is installed, through the surface (machined surface) of these grinding pad 8 abrading glass plates 3 (omitting diagram) at this.
Make the grinding unit 4,4 of such formation ... Eccentric rotation (revolution) is respectively transferred glass plate 3 down at it, thereby is made glass plate 3 by each grinding unit 4,4 on abrasive disk 2 ... Continuously grinding.
And; The formation of lamination rubber unit 12 is; U block 13 (second installing component) is fixed on the abrasive sheet 7; The installation portion 14 (first installing component) that is fixed to gripper shoe 6 is positioned at the central authorities of the peristome of U block 13, and disposes lamination rubber components 15,15 between the U block 13 of the both sides of installation portion 14.
Fig. 4 amplifies this lamination rubber unit 12 of expression.
As shown in Figure 4; The formation of lamination rubber unit 12 is, configuration U block 13, and at the installation portion 14 of the substantial middle portion configuration overshooting shape of the peristome of U block 13; In two gaps between installation portion 14 and U block 13, dispose lamination rubber components 15,15 respectively.
The lamination rubber components is installed at 15,15 o'clock,, is made lamination rubber components 15,15 produce pressure on the contrary not produce the mode of tensile force.For this reason, the for example compressible big lamination rubber components of axial natural length 15,15 of comparing with each gap makes its contraction, is embedded into above-mentioned gap.
For example shown in Fig. 4 (A), the wide of wide jut for L1, installation portion 14 of establishing the peristome of U block 13 is respectively L3, L4 for the gap between L2, installation portion 14 and the U block 13.At this moment, the wide L2 according to the jut of the wide L1 of the peristome of U block 13 and installation portion 14 can make gap L 3, L4 derive as L1-L2=L3+L4.Then prepare the lamination rubber components 15 that natural length surpasses the wide length of L3, L4.And shown in Fig. 4 (B), when grinding, the width of L3, L4 always changes.
Therefore, the preferred natural length of lamination rubber components 15 (the short length of cripetura) can be obtained as follows.
For example, when the lamination rubber components 15 that is provided with among Fig. 4 (B) expression L3 shortens the most when length (cripetura short), select, the natural length L0 that makes the lamination rubber components 15 that is provided with among the L4 promptly satisfies L4＜L0 greater than L4.
So, even installation portion about 14 significantly moves during grinding, lamination rubber components 15 can not be deformed into the length above natural length yet, can prevent the breakage of lamination rubber components 15.
Satisfied this condition, lamination rubber components 15,15 has been shunk and is embedded into the peristome of above-mentioned U block 13 and the gap between the installation portion 14, thereby make pressure be applied to lamination rubber components 15,15.So, tensile force can be do not produced in the lamination rubber components 15,15, the durability of lamination rubber components 15,15 can be improved.
Fig. 5 representes the perspective view of lamination rubber components 15.
Existing lamination rubber components exists because of rotate (slightly departing from a circumferential direction) around central shaft makes the end wear of lamination rubber components and the danger of degenerating; For preventing this point; In this embodiment; As shown in Figure 5, except central shaft 16, another pin 17 (the anti-stop element of rotation) is set.Through in this pin 17 and U block 13 or the installation portion 14 at least one engaged, thereby can prevent that lamination rubber components 15 from rotating around central shaft 16.Promptly preferred: between the lamination rubber components 15 of lamination rubber unit 12 and installation portion 14 and between lamination rubber components 15 and the U block 13, in any at least one between, be provided with and prevent the pin 17 of lamination rubber components 15 around its central shaft rotation.
In addition, except the mode that central shaft 16 and another pin 17 are set, also two pins can be set except central shaft 16.So, the lamination rubber components does not rotate, and can prevent the wearing and tearing of end face.
More than in the example of the grinding unit shown in Figure 24 of explanation, have two air springs 10 and three lamination rubber units 12, Fig. 6 representes the example of bigger grinding unit 4.
Example shown in Figure 6 is configuration air spring 10 and lamination rubber unit 12 on the abrasive sheet 7 of the rectangle of grinding unit 4 all.All represent air spring 10 with circle in the drawings, represent lamination rubber unit 12 with rectangle.
Example shown in Fig. 6 (A) has three air springs 10 and four lamination rubber units 12.In the example shown in Fig. 6 (B), abrasive sheet 7 is bigger, has seven air springs 10 and four lamination rubber units 12.And in the example shown in Fig. 6 (C), it is big that abrasive sheet 7 further becomes, and has ten air springs 10 and eight lamination rubber units.
Therefore, in this embodiment, through using a plurality of lamination rubber units, can corresponding various bigger lapping devices (grinding unit).And, in each lamination rubber unit, in 12,, and prevent its rotation around central shaft to small-sized lamination rubber pressurization, therefore can improve the durability of grinding unit.
More than the example of the lapping device of explanation has used the abrasive sheet of rectangle, and below the example of circular abrasive sheet has been used in explanation.
The summary that Fig. 7 representes to have the abrasive wire of grinding unit constitutes, and above-mentioned grinding unit has circular abrasive sheet.
As shown in Figure 7, this abrasive wire 100 and abrasive wire 1 shown in Figure 1 likewise are made up of following: abrasive disk 2, be equipped with glass plate 3, and transfer to the transfer direction shown in the arrow A direction; Grinding unit 104 (only showing one among Fig. 7) ..., above the glass plate of transferring on the abrasive disk 23, a plurality of along transfer direction A configuration.
Wherein, grinding unit 104 has gripper shoe and abrasive sheet (omitting diagram) therein, disposes eccentric rotating mechanism 106 at an upper portion thereof.Eccentric rotating mechanism 106 makes abrasive sheet shown in arrow B, rotate (rotation) around its central shaft through the gripper shoe in the grinding unit 104; And the point around the central shaft that departs from abrasive sheet when making the abrasive sheet rotation rotates (eccentric rotation, so-called revolution) shown in dotted line and arrow C.And,, grinding pad is set at the lower surface of abrasive sheet though omitted diagram.
And; Though omitted diagram; But, between the gripper shoe and abrasive sheet in this grinding unit 104, a plurality of lamination rubber units that the air spring of grinding pressure are provided and are used for the rotation driving torque is delivered to abrasive sheet to abrasive sheet from gripper shoe are set also with shown in Figure 3 identical.And these a plurality of air springs are configured on the position that the pushing force to glass plate becomes impartial between gripper shoe and abrasive sheet.
The grinding unit 104 that constitutes like this is a plurality of along abrasive wire 100 configurations, make the abrasive sheet rotation and the revolution respectively of each grinding unit 104, thereunder on grinding table 2, transfer glass plate 3, thus continuously grinding glass plate 3.
Fig. 8 representes to be configured in the example of arrangement of gripper shoe and the air spring between the abrasive sheet and the lamination rubber unit of grinding unit 104.
As shown in Figure 8, on abrasive sheet 107, eight air springs 110 and four lamination rubber units 120 are configured in respectively on the uniform position on the abrasive sheet 107 of circle.
And Fig. 9 is illustrated in the example that disposes air spring 110 and lamination rubber unit 120 on the abrasive sheet 107 when grinding unit 104 is more maximized.
In example shown in Figure 9,16 air springs 110 and four lamination rubber units 120 are being arranged on the uniform position on the abrasive sheet 107.
And, when grinding unit 104 is maximized, also must transmit big torque to the lamination rubber unit 120 of abrasive sheet transmission rotation driving torque from gripper shoe, the number that therefore increases lamination rubber is carried out correspondence.
