Actuator and actuator arrangement

An assembly apparatus constructed from a plurality of beam members connected together in a frame, and including a plurality of actuator modules disposed at respective positions around a work table, each of said actuator modules comprising:

• a beam member;
• a drive source held in said beam member;
• a slider base held in said beam member and having a slider displaced along said beam member under the action of said drive source;
• and
• a cover covering said drive source and said slider base held in said beam member;
• said beam members each having at least one groove which enables said beam members to be mounted to other beam members of said work table and said actuator modules, said groove being defined in at least an outer side of said beam members along the longitudinal direction thereof in a substantially identical structure to the other beam members.

An assembly apparatus including a plurality of beam members connected together in a frame and a plurality of actuator modules disposed at respective positions around a worktable, each of said actuator modules comprising:

• a beam member;
• a drive source held in said beam member, said drive source comprising at least one of an electric motor and a rodless cylinder;
• a slider base held in said beam member and having a slider displaced along said beam member under the action of said drive source;
• and
• a cover covering said drive source and said slider base held in said beam member;
• said beam members each having at least one groove which enables said beam members to be mounted to other beam members of said worktable and said actuator modules, said groove being defined in at least an outer side of said beam members along the longitudinal direction thereof in a structure substantially identical to the other beam members;
• and
• a control mechanism integrally disposed on said assembly apparatus, and control mechanism supplying at least one of electric power and air to said actuator modules and controlling movement of said slider.
