Definitions
- the present invention relates to a substrate gripping device, and more particularly to a centering type substrate gripping device used for gripping a substrate such as a semiconductor wafer and transporting it between a cassette carrier and an inspection device.
- gripping of a semiconductor wafer includes a suction hand that holds the back surface of the wafer by suction, and an edge clamp node that grips the edge of the wafer. Since the suction hand has an adverse effect on the back surface of the wafer, in recent years, the edge clamp hand has been frequently used as a wafer gripping device.
- this edge clamp node is gripped by pinching with a holding member having one as a fixed portion and the other as a movable portion (refer to Japanese Patent Application Laid-Open No. 2004-6534).
- a grip so-called centering method; refer to Japanese Utility Model Publication No. 6-37906 that presses the substrate evenly.
- the former gripping operation is performed by moving the movable part after the gripping member that is opened larger than the wafer size approaches the wafer under the force of the wafer so that the wafer comes into contact with one end fixing part.
- the center position is shifted again by the gripping operation.
- the suction holding force of the inspection apparatus or the like receives the wafer, the timing of releasing the suction is bad, and it is difficult to hold it well.
- the clamp mechanism described in Japanese Patent Publication No. 6-37906 performs a centering operation by pulling the two levers, Y-shaped and T-shaped, close to each other, with the pin that engages with the long hole of the lever. Because the long holes naturally have backlash, the movement distances of the Y-shaped and T-shaped levers are not necessarily the same.
- the gripping operation of the edge clamp node grips the wafer using the biasing force of the spring and suppresses the spring force by operating the actuator to release the gripping. In this case, a cylinder with a force exceeding the spring force is required. However, if this is housed in the wrist of an edge clamp hand, the wrist part will inevitably become large. Therefore, the edge clamp node is difficult to use for delivering a substrate to a device having a narrow loading / unloading port.

- the pair of left and right blades move left and right by the same amount in conjunction with the advance and retreat, so that they can move toward and away from each other.
- the advancing / retreating mechanism of the slider includes an actuator and an elastic body that exerts an urging force that interferes with the acting force of the actuator, and the slider includes the actuator.
- the forward movement is caused by the resultant damping force of the actuator acting force and the urging force of the elastic body, but the forward movement causes the pair of left and right blades to approach each other and their gripping portions abut against the substrate. Even after stopping, the pair of left and right blurs continue to receive the resultant force that gradually decreases.
- the substrate gripping apparatus is characterized in that both grip portions of the door can grip the substrate with a predetermined strength.
- the pair of left and right blades move left and right by an equal amount and approach each other by the forward movement of the slider, and the substrate can be gripped by both side forces in the left and right direction.
- the forward thrust is due to the resultant damping force of the acting force of the actuator and the biasing force of the elastic body that interferes with this, and the slider advances and the pair of left and right blades approach each other. Even if the slider stops due to contact with the substrate, the gripping force of the pair of left and right blades will continue to receive the resultant force that gradually decreases so that the substrate is gripped with a predetermined strength. Can do.
- the slider moves backward due to the biasing force of the elastic body, and the pair of left and right blades move left and right by equal amounts. They can be separated from each other to release the substrate.

Since the acting force of the actuator is small, the actuator can be reduced in size, and if this is stored in the wrist portion of the substrate gripping device, the wrist portion will not be enlarged. . As a result, the substrate gripping apparatus can be satisfactorily used for delivering a substrate to an apparatus having a narrow carry-in / out opening.
- the substrate is gripped only by the acting force of the actuator, there is a manufacturing error in the substrate, and therefore there is a possibility of breaking the substrate.
- the acting force of the actuator Since the slider moves forward and the pair of left and right blades approach each other and their gripping portions abut against the substrate, the slider stops and is gradually relaxed by the urging force of the interference elastic body.
- the gripping force of the substrate which is the resultant force, is also reduced as the gripping progresses, so that the gripping portions of the pair of left and right blades can grip the substrate with a predetermined strength, eliminating the possibility of breaking the substrate.
- the operation of one actuator causes the substrate to be sandwiched between the pair of left and right blades, and all the grip points of the blades of the pair of left and right blades have the same timing toward the center position of the substrate. So that the same distance can be moved accurately.
- the center position is shifted again due to the gripping operation, it is a must! ,.
- each grip portion of the pair of left and right blades has a recess that receives the edge of the substrate, and the eccentric receiving seating force whose fixed position is variable about the eccentric shaft is obtained.
- the arrangement of all the gripping portions on the pair of left and right blades matches the contour shape of the substrate of a predetermined shape such as a circle, so that it can be gripped without backlash. By rotating the receiving seat, it is easy to adjust the position of the grip.
- the elastic body has a spring force.

- the substrate gripping device of the invention of the present application like the conventional centering type substrate gripping device, the substrate is gripped using the biasing force of the spring, and the actuator is operated to actuate the spring. Since it is not intended to release the gripping of the board by suppressing the urging force, the acting force of the actuator can be reduced, and the actuator can be miniaturized and stored in the wrist part of the board gripping device. As a result, the wrist portion does not increase in size. As a result, the substrate gripping apparatus can be satisfactorily used for delivering a substrate to an apparatus having a narrow carry-in / out opening.
- the substrate is held only by the acting force of the actuator, there is a manufacturing error in the substrate, and there is a possibility that the substrate may be broken.
- the acting force of the actuator advances the slider. Even after the pair of left and right blades approach each other and their gripping portions come into contact with the base plate and the slider stops, the slider is gradually relaxed by the urging force of the interference elastic body. The gripping force is also eased as the gripping progresses, so that the gripping portions of the pair of left and right blades can grip the substrate with a predetermined strength, and the possibility of breaking the substrate is eliminated.
