A multi-hole absorption tool includes an absorption surface including a plurality of absorption holes to which a seal is absorbed. Each of the plurality of absorption holes is classified so as to belong to at least one of a first region and a second region, and absorption holes belonging to the first region and absorption holes belonging to the second region are connected to different suction devices. The multi-hole absorption tool having this configuration can peel off the seal from a mount with no wrinkle in the seal, prevent positional displacement of the seal with respect to an object to which the seal is affixed, and affix the seal to the object.

The present invention relates to a micro LED grip body and a system having the same for inspecting a micro LED, the micro LED grip body having a vacuum-suction structure capable of being used for transferring a micro LED, thereby solving problems of micro LED transfer heads that have been proposed in the related art.

A vacuum-based end effector for engaging parcels includes a base plate, one or more vacuum cups of a first type, and one or more vacuum cups of a second type. Each vacuum cup of the vacuum-based end effector is configured to be placed in fluid communication with a vacuum source to provide the vacuum cup with a suction force which can be used to engage and grasp parcels. Each vacuum cup includes a bellows defining a pathway for a flow of air and a lip connected to the bellows. Each lip of the one or more vacuum cups of the first type comprises a foam lip, and each lip of the one or more vacuum cups of the second type comprises an elastomeric lip. The vacuum-based end effector can be combined with a robot to provide an improved system for engaging parcels.

Systems, methods, and computer-readable media are disclosed for robotic picking assemblies configured to grasp multiple items. In one embodiment, an example system may include a picking assembly coupled to a vacuum system, the picking assembly having a first suction cup assembly with a first suction cup and a first sensor, and a second suction cup assembly with a second suction cup and a second sensor. The example system may include a controller configured to cause the picking assembly to grasp a plurality of items, where the plurality of items includes a first item and a second item. The controller may be further configured to cause the picking assembly to move from a first position to a second position, and cause the picking assembly to release the first item at a first time and the second item at a second time.

A suction pad configured to suck and hold a fruit includes a pad main body made from an elastically deformable member and having a held base end portion; a hollow formed inside the pad main body so as to extend from a base end side to a tip end side; and a hole configured to communicate with the hollow and being open to a tip end portion of the pad main body, and an opening diameter of the suction hole is smaller than an inner diameter of the hollow.

An end effector is disclosed for an articulated arm. The end effector includes a valve assembly including a plurality of supply channels, each supply channel including a supply conduit, a pressure sensor in fluid communication with the supply conduit, and a supply conduit plug. The supply conduit is in fluid communication with a vacuum source. During use, each supply conduit is either at vacuum such that the pressure within the supply conduit is substantially at a vacuum pressure, or is at a pressure that is substantially higher than vacuum pressure because the supply conduit plug has moved to block a portion of the supply conduit. The pressure sensor of each supply conduit provides a pressure sensor signal responsive to whether the pressure in the conduit is either substantially at vacuum or is at a pressure that is substantially higher than vacuum.

In a soft grip head, a soft grip unit having the soft grip head, and a grip device having the soft grip unit, the soft grip head has a suction pad and the suction pad makes contact with an object. The suction pad includes a sidewall and a plurality of suction cells. The sidewall divides the suction pad into a plurality of spaces, and both ends of each of the spaces are open. A plurality of suction cells is respectively formed by the spaces divided by the sidewall. The suction pad includes a material having a stiffness along an axial direction smaller than a stiffness along a width direction. The suction cells extend along the axial direction, and the width direction is substantially perpendicular to the axial direction.

The polymer film of the present invention has through holes extending from one principal surface of the polymer film to the other principal surface of the polymer film. The through holes are straight holes having a central axis extending straight, and have a shape in which the area of a cross-section perpendicular to the direction of the central axis increases from the one principal surface of the polymer film toward the other principal surface. This polymer film has passages in its thickness direction, has an unconventional structure, and can be used in various applications, such as in a waterproof sound-permeable membrane, in a waterproof gas-permeable membrane, and in a suction sheet. The ratio a/b of the opening diameter a of the through holes at the one principal surface to the opening diameter b of the through holes at the other principal surface is 80% or is less than 80%.

In a suction nozzle 66 which sucks and holds a component 150 on a suction surface by using negative pressure air and detaches the sucked and held component from the suction surface by using positive pressure air, the positive pressure air and the negative pressure air used when the component is held and detached selectively flow through through-holes 90, 94 and 96, air flow path 116, or the like. In addition, a rod 110 is held to be capable of being advanced and retracted toward the suction surface in an inside section of the suction nozzle. The rod protrudes from the suction surface by the positive pressure air flowing through the air flow path and is retracted to the inside section of the suction nozzle when the negative pressure flows through the air flow path. In other words, the through-hole, the air flow path, or the like is shared as a mechanism for moving the rod and a mechanism for sucking and holding the component by the suction nozzle. Accordingly, it is possible to make the device compact, simple or the like and to improve practicality of the suction nozzle.
