In an automated production plant, the feeding of parts to a robot or handling device is one of the most important processes. If the alignment or position of the workpiece is inaccurate, this can lead to malfunctions and the system will not work efficiently. Often, sensitive or complex shaped parts cannot be fed with a vibratory bowl feeder. Such workpieces have to be stored in pallets, trays, blisters or cups then and fed into the production process in an orderly manner. The palletizers or depalletizers from Hirata solve the feeding and changing of such trays in an economic and reliable way.
Depending on the task, robots with different kinematics support the assembly and handling of components in an automation system. Four-axis SCARA robots from Hirata are ideally suited for fast and flexible assembly and handling tasks. Hirata 6-axis robots can be used for very complex workflows in component manufacturing and assembly due to their six degrees of freedom. A big advantage of these two robot types is the repeatability. Robot systems work with a professional design with highest, constant quality.
Automation in semiconductor production requires special production equipment that is adapted to the specifics of the materials and process steps. Especially the handling of the sensitive wafers in an atmospheric environment places the highest demands on cleanliness and gentle material handling. Hirata offers standardized components for this area like atmospheric and vacuum robots, foup openers and autodoor FOSBOpener for safe opening and closing of the foups as well as prealigner for precise alignment of the substrates and SMIF Pods Opener for handling of wafers and EFEM equipment.
The freely programmable linear axis systems of Hirata are offered as a modular system. This means that the user can assemble the suitable system from a number of axis models. The number of axes and stroke lengths, the speed, handling weight and positioning accuracy are essential selection criteria. The devices are mainly used for tool and workpiece handling. Especially for the assembly or handling of very large and heavy components Hirata offers Gantry Robots . These gantry robots with three axes have a very high stability and can also be configured according to the customer's needs.
With the palletizer model SAST Hirata automates the palletizing of trays or KLTs directly from standard floor rollers, which are more and more used in internal material logistics. The SAST palletizing system is very compact and requires only a small footprint. It ensures, for example, automated material supply and/or removal at an assembly, test or production plant and at machine tools, etc.
Because of its well thought-out design, level differences on the floor roller or uneven floors no longer play a role to a certain extent. The integrated safety technology enables the floor rollers to be changed while a tray is being processed. In addition, the palletizer can process different tray heights without changeover due to its freely programmable servo axes.
