Title: System and method for recirculating partsApplicant: Rixan Associates, Inc. (USA)Patent number: US2010063629(A1)Publication date: March 11, 2010
This invention relates to a system and method for feeding and recirculating parts for vision-based pickup. The system and method have a feeder that automatically recirculates parts that are not picked by a robot. The system has a feeder bowl, ramp and interchangeable picking plate, all of which may be vibrated to both feed parts and cause recirculation.
Title: Vision-guided pick-and-place deviceApplicant: Univ. Huazhong Science Tech. (CN)Patent number: CN201302987(Y)Publication date: September 2, 2009
The utility model provides a vision-guided pick-and-place device used in IC encapsulation process which requires precise positioning and pick-and-place. The vision-guided pick-and-place device comprises a base, a mounting head, a camera, a microprocessor, a first positioning table, a second positioning table, and two anti-collision protection circuits. The first positioning table and the second positioning table move toward the x-direction on the surface of the base. The mounting head is installed on the first positioning table. The camera is installed on the second positioning table. The mounting head and the camera move toward the y-direction relatively to the base. The two anti-collision protection circuits are arranged, respectively, on the first positioning table and the second positioning table. The utility model has the advantages that the synchronous operation of vision mechanism and mounting head is realized, the load of the positioning tables is reduced, the operation speed of the positioning tables is improved, and the safe, reliable and high-speed operation of the movable table is ensured.
Title: Method of treating objects according to their individual weightsApplicant: Arbor SA (FR); Nignon Gilles (FR)Patent number: WO2010037942(A1)Publication date: April 8, 2010
In order to divide up objects having a random distribution of weights, so as to treat the objects according to their weights, the method comprises the following steps carried out cyclically: detection of an object; grasping of the detected object by means of a gripper mounted on a robot and measurement of the weight by means of a weight or force sensor placed on the gripper, on the robot or on a member for anchoring the robot; and acquisition of the weight by associating it with the object.
Title: Article picking deviceApplicant: Fanuc, LtdPatent number: JP2010012567(A)Publication date: January 21, 2010
Problem to be solved: to provide an article picking device manufacturable at low cost, and speedily and accurately picking an article from a random pile state.
A target detecting part of an image processing part processes an image captured by a video camera and detects objects. A target selecting part selects an object among the detected objects based on a certain rule. A view line calculating part calculates the direction of a view line extending to the selected object. A target position estimating part estimates the position including of the selected object including the height based on size information of the object in the image. Then, a grip correction calculating part calculates an amount of correction of the movement of a robot so as to grip the object by using the robot.
Title: Robotic picking of parts from a bin using force feedbackApplicant: ABB Research, Ltd (CH); Fuhlbrigge Thomas A (USA); Martinez Carlos (USA); Chen Heping (USA); Rossano Gregory (USA); West Steven (USA) LtdPatent number: WO2010024795(A1)Publication date: March 4, 2010
A robot is used to pick parts from a bin. The robot has a compliant apparatus and one or more tools are connected to the apparatus to perform the picking. The compliant apparatus has mechanisms for monitoring and/or controlling its compliance. The compliant apparatus can have various embodiments. Force sensing can be used during removal of grasped parts from the bin to determine the force exerted on the picking tool(s). The signal indicative of the exerted force can be used by the robot controller to determine the weight of the parts that may be held by the picking tool(s). The robot has one or more devices which can be the picking tool to stir the parts in the bin.
Title: Bin picking apparatusApplicant: Kondo Machine WorksPatent number JP2010105081(A)Publication date: May 13, 2010
Problem to be solved
To provide a bin picking apparatus capable of carrying workpieces in a pallet without wasting them and carrying the workpiece by securely holding it with a holding device even at any attitude.
In the bin picking apparatus, the position and attitude of the pallet storing the workpieces in an unaligned state is three-dimensionally measured by a measuring device using an imaging device, and the workpieces are conveyed by a conveyance device connected with the holding device for holding the workpiece in the pallet using a control device for transmitting a command to the conveyance device based on the result of the measurement by a detection device. The bottom surface of the pallet and the wall surfaces in four directions of the pallet are divided, a drive device in which the bottom surface of the pallet and the wall surfaces of the pallet are relatively and vertically moved is arranged, and the height of the wall surfaces of the pallet is varied corresponding to the height of the workpieces in the pallet.
