Abstract

Here, the holding means including the component 10 capable of volume control and the volume controller capable of operating the component 10 will be described. The volume controller is configured to give the component 10 a condition that causes a physical volume change without a mass change. This volume change causes a holding force. Furthermore, here, a method of generating a negative pressure between a volume-controllable mass-invariant component 10 and a separate object 30 is shown. The method includes introducing an increase condition to the component 10 that increases the volume without a mass change. The separate object 30 is then brought into contact with the component 10 where a reduction condition is introduced later that reduces the volume without a mass change.

Description

Advances in accuracy, tolerance, accuracy, efficiency, etc. are desirable and can be achieved in all processes in which an object can be held. Holding devices and / or mounting devices range from very simple to very complex, but basically have the same purpose. One of those objectives is to hold the object at a point or set of points and help the process being applied to the object.

Retention technology has become a potential barrier in recent years when available time has decreased, production demands have increased, and sometimes the fragility of objects to be retained has further increased. Therefore, new holding devices and fixing devices are constantly needed to meet these requirements.

Here, a holding unit having a volume controllable component and a volume controller capable of operating the component is shown. The volume controller is configured to give the component a condition that causes a physical volume change without mass change. This volume change produces a holding force.

Further, here, a holding unit having a density controllable component and a density controller capable of operating the component is shown. The density controller is configured to give the component a condition that causes a physical density change without mass change. This density change creates a holding force.

In addition, here is shown a method for creating a negative pressure between a volume-controllable mass-invariant component and a separate object.
The method includes introducing an increase condition to the component that increases the volume without a mass change. The separate object is then brought into contact with a component that is subsequently introduced with a reduction condition that reduces the volume without a mass change.

In addition, here we show how to create a negative pressure between a density-controllable mass-invariant component and a separate object.
The method includes introducing a reduction condition to the component that reduces the density without a mass change. The separate object is then brought into contact with a component that is later introduced with increasing conditions that increase the density without a mass change.

Furthermore, here is a method for holding an object, introducing a condition for changing the volume without mass change to a volume-controllable component, bringing the object into contact with the component, and , A method for holding an object that includes introducing another condition to change volume without mass change for a volume controllable component. Holding is caused by this volume change.

Furthermore, here is shown an anchoring device with an end effector that includes components having at least a highly flexible state and a lowly flexible state, both states being reversible and repeatable. The flexibility controller is configured to introduce to the component a condition that changes its state between a highly flexible state and a low flexible state.

Further, here is a method for fixing an object, including a method for fixing an object, including placing a component of an end effector in a highly flexible state and contacting the object with the component. The component is then transitioned to a low flexibility state.

Furthermore, a fixing device including a number of components is shown here. The component controller is operable to operate the component and is configured to introduce a condition that reversibly and repeatably changes a number of components between a low flexible state and a high flexible state. ing.

Reference is now made to the drawings. Note that similar numbers are assigned to similar elements.

The methods and apparatus described herein are suitable for holding a number of different objects. The function of holding and releasing is started quickly, can be easily and rapidly reversed and repeated, and has low impact on the object to be held or fixed. Here, the term “holding” means that it can withstand a load that acts to remove an object from the holding device in the axial direction, the lateral direction, or the rotational direction. Also, here, fixation means torsional resistance against movement and lateral resistance resulting from the applied normal force, and is specific to the load acting to separate the object axially from the fixing device. It means that there is no resistance. That is, in the case of fixing, it is not always necessary to indicate a lack of resistance to the axial load.

All of the examples shown here depend on the deformable properties of the components used. The component has the property that it can be highly flexible so that it immediately follows the shape of the pressed object. Thereafter, the component can be relatively flexible with its shape relatively easily. The component is also reversible and repeatable. In addition, some of the examples given here depend on another property of the deformable component, i.e. the property that can control volume changes or density changes without mass changes. is doing. If such changes are properly applied, as shown here, a deformable component or a device comprising a deformable component can be used to hold an object. Holding can be done by negative pressure generated at the contact surface between the holding device and the object. In such cases, negative pressure is caused by changes in volume and / or density, as mentioned. If necessary, the effect can be increased by depressurization by other applications without departing from the scope of the present invention which provides at least initial or supplemental retention by deformable component changes. Furthermore, similar properties with changes in volume or density that can cause negative pressure can be used to produce a reversible interference fit suitable for holding an object. More specifically, if the component is properly formed to fit into the recess and its density is large or its volume is small, then by introducing conditions to increase or decrease the volume, The component produces an interference fit in the recess.

Components that vary in volume and / or density without mass change include polymers, monomers, waxes, magnetorheological materials, electroheological materials, thermal active materials, alloy materials such as metals Or composite materials containing at least one of these materials. One typical component is freebond® (a wax composite) commercially available from Gerber Coburn Optical, Inc. (South Windsor, Conn.). In addition, the component includes an electrical resistive material, a magnetoresistive material, and a piezoelectric material, or a composite material including at least one of these materials.

Conditions that cause the desired change include increasing and decreasing conditions consisting of application of potential, magnetic field, temperature change, pressure change, and other conditions. These conditions, when combined with certain components, cause a change in volume or density without mass change, while at the same time causing a change between a highly flexible state and a low flexible state. “Increase” and “decrease” are used as condition names to identify them when both are used. The “increase” condition is used when the volume or density increases, and the “decrease” condition is used when the volume or density decreases. This is a simplification for the claims. That is, those skilled in the art will understand that decreasing density is accompanied by increasing volume (and vice versa).

Under appropriate conditions that can be applied by one controller (or multiple controllers), the component becomes highly flexible. The controller may be a temperature adjustable fluid conduit, electrical conductor, magnetic field generator, pressure generator, and the like. When a particular component is in a liquid state or eluting state, it is desirable to confine this component in some way to avoid its loss. For example, at least when a component is in a highly flexible state and when transitioning from a highly flexible state to a lowly flexible state, a cover that is flexible and elastically stretchable is disposed on the component. Also good. Such a cover may be a plastic material such as a thermosetting material, a thermoplastic material, and an elastomeric material (eg, vinyl). A cover is not necessary if the components used are confined by themselves.

For a better understanding of the method and apparatus disclosed herein, reference is made to FIG. 1, which schematically illustrates apparatus 10, deformable component 20, and object 30. In a highly flexible state after introducing conditions that can make a particular component highly flexible, the volume of the component increases and the density decreases accordingly. This is important for reasons that will become apparent below. While in the highly flexible state, the component 20 is brought into contact with the object 30 to be held. The deformable component 20 deforms following the surface 32 that forms the object 30. In this way, the component 20 whose surface is perfectly aligned will be in direct contact with it at all locations, thus facilitating sealing with the surface of the object 30.

When a condition for low flexibility is introduced for the component 20, the component 20 experiences the negative pressure discussed above between the component 20 and the object 30, and has a volume rather than a mass. Decrease. The change in volume causes a dimensional change that causes a pressure drop. The component retracts from the object while still in contact with the object around it. The volume of the space between the component and the object becomes larger, but the pressure in that space necessarily drops because the fluid cannot move into that space. The object 30 is efficiently held by the negative pressure. In order to increase the pressure generated, one embodiment is comprised of a component 20 and a support member 40, with the component 20 having a central portion that is substantially thicker than its peripheral edge 22. The recess of the support member 40 in which the component 20 is installed is schematically illustrated by the broken line 42. The center of the recess is deeper than the perimeter, as will be appreciated by those skilled in the art. This is useful for the purposes described above, as the volume change is proportional to the volume of the utilized component. Therefore, when the volume (thickness) of the component increases toward the central region, the amount of decrease in the volume increases toward the central region. In this embodiment, the peripheral area does not change in dimension as much as the change in the central area, but increases the contact pressure at the periphery, so in addition to increasing the pressure difference, the contact pressure on the object at the periphery of the component 20 To strengthen. Such a situation helps to maintain the pressure differential for a longer period.

With reference to FIGS. 2A and 2B, another embodiment of a holding device is shown. This exemplary embodiment is configured on the base 50. Base 50 has several features configured to enhance the operation of the device. The accumulator cavity 52 is located in a position that allows the component 20 to be urged into it. This makes it easier for the device to work because the components do not have to move outward to fit the surface and can be moved into the base. The advantage of this method is that, depending on the shape of the object pressed against the component, the component can be adapted to a large number of differently shaped objects by moving it more or less into its cavity. Component 20 is physically separated from the cavity by a resilient membrane 54. When the component 20 is pressed against the object to be held, the membrane 54 refracts into the cavity 52. The resilient membrane 54 also returns the component from the base 50 outward if the component is not urged inward by the object. This is intended to reset the holding device when it is next made highly flexible.

As shown in the drawing, a part of the membrane 54 is captured by a retainer 56 press-fitted into the recess 58, and the position thereof is maintained. The membrane 54 is further held by a retaining ring 60 that is attached to the base 50 by fasteners 62. The holding ring 60 further includes a recess 64 at the periphery. The recess is configured to receive a cover 66 and a spline 68 that can be an O-ring. Once the spline 68 is installed, the cover 66 is securely held and holds the component 20. This is beneficial if the component 20 is one that elutes in a highly flexible state.

In this embodiment, the component 20 consists of two substances. Portion 20a is a wax and portion 20b is an alloy. This is beneficial to accommodate objects with a sharper tip and a rigid base structure. In addition, the alloy generates heat rapidly, which helps to transfer heat to the braze and make it faster and more flexible. The braze part and the alloy part are not mixed because the specific gravity of the composite material is greatly different. Even if the components become discontinuous due to mechanical interference with use, they will separate easily and rapidly. The alloy part 20b is always stable below the brazing part 20a. Wax and alloy are just one example of the devices described herein. Other combinations of components can also be used with the same results. Also, keeping in mind the end goal of the device as described above, other combinations may be desirable in some circumstances.

With reference to FIGS. 3A and 3B, another embodiment of the apparatus is shown. The base 150 includes an accumulator cavity 152. A membrane 154, a retainer 156 and a cover 166 are provided and are similar to the previous embodiment. The components are not identical to the previous embodiment, but they can be identified by those skilled in the art. The previous embodiment differs from the channel block 180 received in the base 150 and with a flow channel 182 for the component 20. Component 20 is disposed on flow channel 182 and reservoir 184 and between cover 166 and channel block 180.

By applying a condition that makes the component 20 highly flexible and a compressive force applied to the cover 166, the component 20 flows through the flow channel 182 and has elasticity similar to that of the previous embodiment and having the same effect. The film 154 having a thickness is refracted. Membrane 154 also helps in resetting the device to be highly flexible, as in previous embodiments.

In each of the previous embodiments, the controller 200 (or a number of controllers) is provided. The controller is operable to operate the component 20 and is configured to introduce a condition that causes the component to transition between the low and high flexibility states (in both directions). The required conditions depend on the composition of component 20.

One or more of the above devices may be used together. For example, small objects (eg, ophthalmic lenses, watch cases, etc.) can be held by one of these devices. However, large objects (eg, wide panes, stone slabs, etc.) may be held by more than one of these devices. Furthermore, the device does not require a single plane. More precisely, they may be placed on individual actuators and may also hold non-planar shaped objects as illustrated in FIG.

Further, a sensor schematically illustrated in FIG. 5 may be provided in the device 10 to effectively sense the holding force of the device. This may sense the pressure difference at the contact portion between the device and the object.

As is apparent from the above, the method of holding an object includes the steps of introducing a condition that makes the component highly flexible, pressing the object against the component to deform into the same shape, and the component And a step of introducing a condition for making the flexibility low. This contact retention is repeatable.

Another embodiment of the apparatus and method presented here does not require retention characteristics (as revealed in this specification), but utilizes a structure where the surface is exactly the same between the component and the fixed object There are fixing steps that can be performed. The concept shown above is useful for such a fixing process. This is especially true when the fixation device contacts the object from two opposing surfaces and some normal force is applied. In this type of application, volume changes or density changes are not important. In this type of application, the required properties of the component can be rapidly, reversible, repeatable and easily highly flexible and low flexible, and the fixing device can be applied to the torque or lateral force applied to the fixed object. It is resistant to directional forces. This can be achieved by using polymers, monomers, waxes, magnetorheological materials, electrorheological materials, thermally active materials, alloy materials such as metals, or composite materials containing at least one of these materials. Achieved. One typical component is freebond® (a wax composite) commercially available from Gerber Coburn Optical, Inc. (South Windsor, Conn.). The component further includes an electrical resistive material, a magnetoresistive material, and a piezoelectric material, or a composite material comprising at least one of these materials. This is because, of course, the component has the shape of the surface of the object, and then the shape remains low and flexible.

FIG. 6 illustrates one embodiment of this concept. The device 210 is very similar to the holding device described above and uses a component 220 that can transition between a highly flexible state and a lowly flexible state, but does not necessarily require a change in volume or density. Is different. Any component having suitable properties may be used that does not necessarily produce a holding force, including an electrorheological material, a magnetorheological material, a thermally active material, and the like. Furthermore, the fixation device uses a relatively small end effector (eg, compared to a lateral dimension such as a diameter). Thus, even when components that cause retention as described above are used, no significant retention has been produced in smaller anchoring devices. For larger fixation devices, the holding force is generated sufficiently, but as noted, it is not the purpose of the fixation device. The closely matched surface features of the object 230 and the component 220 provide the desired securing capability. As one example, such a device is useful for finishing ophthalmic lenses.

The second end effector 240 is used to hold the object in place. The second end effector may consist of any component. As one example, effector 240 is configured and functions similarly to device 210.

Multiple controllers may be used if necessary.

Two holding devices can be placed opposite each other to create a torque limiting coupling that provides an easy and quick reset action.

While the preferred embodiment of the invention has been illustrated and described, various modifications and substitutions may be made without departing from the spirit and scope of the invention. Accordingly, while the present invention has been described with reference to the drawings, it is not limited thereto.
