摘要： A system for fabrication of a wind turbine blade including a laser projection which identifies the dimensions for a plurality of layup segments; determines the sequence of layup segments within first and second sections of the mold, wherein the sequence of layup segments within the second section of the mold are synchronized with the layup segments within a first section of the mold. The system also includes a projection device visually depicting the boundaries of a plurality of layup segments onto the mold. This system automates fabrication of composite structures by setting a pace for each task and ensuring operators complete each task within the allotted period. The projection system and layup delivery mechanism can advance with respect the mold to ensure the pace is maintained and an overall product cycle time is adhered to.

摘要： A method to design the kits and layup the reinforcement layers and core using projection system, comprising a mold having a contoured surface; a layup projection generator which: defines a plurality of mold sections; identifies the dimensions and location for a plurality of layup segments. A model-based calibration method for alignment of laser projection system is provided in which mold features are drawn digitally, incorporated into the plug(s) which form the wind turbine blade mold, and transferred into the mold. The mold also includes reflective targets which are keyed to the molded geometry wherein their position is calculated from the 3D model. This method ensures the precision level required from projection system to effectively assist with fabrication of wind turbine blades. In this method, digital location of reflectors is utilized to compensate for the mold deformations.

摘要： The invention relates to a device for handling and/or transporting workpieces (5), in particular for removal of injection-molded items from an injection-molding machine, wherein a handling robot (4) having a programmable control and regulating unit (10) is provided that comprises a gripper (6) having at least one suction nozzle (7) for grasping of the workpiece (5) or fixating it by suction. In the gripper (6) of the handling robot (4) a distance-measuring device (8) for detection of the distance (a1+a2) from the gripper (6) to a reference point or a reference surface (9), for example to the mold tool half (2), which is preferably movable, with the workpiece (5), is provided. The measured value of the distance-measuring device (8) is fed into the control and regulation unit (10). The distance-measuring device (8) can be a light-transit time measuring device, in particular a time-of-flight (TOF) sensor.

摘要： In an injection molding process, it can be difficult to detect, in real time, process control variables such as pressure and temperature. Traditional temperature detectors and pressure sensors can be difficult to place in or near a mold cavity. An example embodiment of the present invention includes a self-powered multivariate sensor and uses acoustic transmission. The sensor may employ an infra-red thermal detector and pressure sensor and transmit coded representations of measurements acoustically via a body of the mold. From the temperature and pressure, melt velocity and melt viscosity of a compound in the mold can be determined with a high degree of accuracy by a processor internal to or external from the sensor. The example embodiment maintains structural integrity of the mold, provides a wireless self-powered sensor, and makes available sensing of properties of the viscous compound to enable injection molded parts production at a success rate exceeding 90%.

摘要： An injection control method controls an injection mechanism configured to inject an injection material into a cavity of a mold. The method includes a detection step for detecting that the injection material reaches a predetermined position in the cavity that is away from the injection position, and a change step for changing the injection termination time based on the time period from injection start of the injection material until the detection in the detection step.

摘要： A mold includes upper and lower mold members and a machine control unit. The lower mold member includes a support board, a molding mechanism mounted on the support board, and an ejection mechanism. The support board forms a receiving compartment. The molding mechanism includes a mold cavity. The machine control unit is mounted in the receiving compartment of the support board and includes an optic sensor. With the arrangement of the optic sensor of the machine control unit, the mold can detect the returned and non-returned statuses of the ejection mechanism and transmits the result of detection to the molding machine of the mold, whereby the molding machine can be timely and correctly informed of the status of the ejection mechanism for correctly issuing a subsequent operation instruction. In this way, the potential risk that the mold is damaged by improper operation of the molding machine can be eliminated.
