摘要:
A device for the application of a liquid fluid to a peripheral area of a lid using pistols for injecting said liquid fluid. The device includes an articulated mechanical device combined with at least two coaxial tubular shafts: a main supply shaft and a lower shaft, where a lower end of the main supply shaft connects to a first part of the articulated mechanical device, while a second part of the articulated mechanical device connects to a lower end of the lower shaft. The two coaxial tubular shafts rotate independently by means of transmission devices. The main supply shaft is arranged in glean inner hole of the lower shaft, which is arranged coaxially around at least one section of the main supply shaft.

An apparatus for depositing and/or jetting viscous medium on a surface of a workpiece includes at least two depositing head assemblies. The at least two depositing head assemblies are configured to move in three dimensional space. The at least two depositing head assemblies are also configured to at least one of concurrently and simultaneously deposit the viscous medium on the workpiece.
摘要:
A device for depositing an organic material includes a substrate; a mask having an opening portion and a shield portion; a fixing member for fixing the substrate and the mask to each other; a deposition source comprising a plurality of nozzles arranged in a first direction and configured to spray the organic material; and a plurality of shield plates near the plurality of nozzles on the deposition source. An angle θ between the substrate and a line extended from a distal end of one of the nozzles to a center of a distal end of a corresponding one of the shield plates is greater than or equal to a taper angle Φ of the shield portion of the mask.
摘要:
A device configured to dispense material at two locations on an electronic device separated by a distance may comprise a controller and first and second material dispensing units comprising, respectively, a first body portion terminated by a first needle portion that defines a first longitudinal axis and a second body portion terminated by a second needle portion that defines a second longitudinal axis. The first and second needle portions may be configured to dispense material onto the electronic device. A positioning assembly may be configured to position the first and second material dispensing units, under control of the controller, such that the first and second longitudinal axes intersect (or appear to intersect from one or more points of view) and such that the material dispensing free ends of the first and second needle portions are spaced away from one another by the distance separating the two predetermined locations.
摘要:
A traveling sprinkler system comprising: a sphere shaped surface; at least one wheel over a circumference of the sphere shaped surface, where the at least one wheel divides the sphere into a first half and a second half; a plurality of holes on both the first half and the second half of the sphere shaped surface; a water hose receptacle, where the water hose receptacle receives a flow of water from a water hose; and wheel gears within the sphere, where the flow of water transfers over the wheel gears to enable the movement of the at least one wheel and the flow of water transfers through the plurality of holes creating a sprinkling action.
摘要:
A method of applying a homogeneous layer of a coating material on a surface with a manually operated application device is presented, the device comprising a number of drop-on-demand printing nozzles perpendicularly to a main direction of movement, with means for measuring the movement with respect to the surface and with an electronic printing nozzle control, characterized by the steps, that an operator makes a selection of the printing nozzles, that the application device gives the operator feedback on the selection made, that the operator moves the application device over the surface, wherein the movement of the application device is measured continuously, that the selected print nozzles are driven with a clock rate that is based on their respective speed and which is configured that successive printing dots overlap, and that those nozzles of the selection, which have a negative velocity component with respect to the main direction of movement, are not be actuated.
