摘要： PROBLEM TO BE SOLVED: To provide a workpiece carrying tool which can stably hold a workpiece.
SOLUTION: According to the structure of the workpiece carrying tool 40, chains 43 and wires 80 which hang a workpiece holding unit 42 are diagonally hung with respect to the vertical direction, and function to horizontally pull the workpiece holding unit 42, respectively, and therefore the workpiece holding unit 42 is stably held at a predetermined horizontal location with respect to an upper base 41. Thus the workpiece 50 can be more stably held and carried than before. Further before the workpiece 50 is held by the workpiece holding unit 42, an inclination of a lower base with respect to the upper base is allowed by canceling locking by a locking unit 60, and after holding of the workpiece by the workpiece holding unit 42, the workpiece holding unit 42 is locked (fixed) to the upper base 41 by the locking unit 60, and therefore the workpiece 50 is further stably carried than before.

Then, a ball screw 11 is rotated by actuating a servo motor 9, a spindle 6 is moved downward with a nut 8, an upper side electrode 3 is lowered, a work is clamped between the upper side electrode 3 and a lower side electrode 2, and the work is subjected to spot-welding by applying voltage to the upper side electrode 3 and the lower side electrode 2. Further, at the time of teaching a robot 12 spot welding positions for the work, the rotation of the ball screw 22 is restricted to put it in a locked state by energizing the electromagnetic brake 24 of the equalizing mechanism 24, and oscillation of the gun body 1 is restricted.

摘要： PURPOSE:To simultaneously coat at least three points by controlling the moving velocity and the rotating speed of a holder so that the locus of the tip of a nozzle is specified. CONSTITUTION:After a first coating point 60 of the face 58 to be coated is coated with an adhesive, the arm of a robot is actuated and horizontally moved to a second coating point 62. When the space L2 between the first coating point 60 and the second coating point 62 is equal to height L1, a time during which a holder 38 is moved to the second coating point 62 from the first coating point 60 is made same as a time during which the holder 38 is rotated at 90 deg.. In this case, a second nozzle 48 is directed downward on the second coating point 62 and the adhesive is dropped. Nozzles 50, 52 are successively directed downward and a third and fourth coating points are coated with the adhesive. Thereby multipoints are coated with the adhesive precisely and efficiently.

摘要： PURPOSE:To provide a four-side trimming device for a work to which a jig can be efficiently attached to a work so as to respond to various kings of works despite of a small space and which responds to work positioning errors, etc. so as to perform highly accurate processing. CONSTITUTION:A necessary jig is taken out in jig stage shift devices 20, 30 according to kinds of works. An unprocessed work is transferred by a robot 8, to a jig positioning position of a jig shift device where a jig is taken out. Then, the jig shift device 50 simultaneously shifts a processed work in the receipt position of a work carrier 10 and the unprocessed work in the jig positioning position transferred at present so that the processed work is positioned in another jig positioning position and the unprocessed work is positioned in the receipt position. After that, the unprocessed work loaded on the work carrier 10 is trimming processed by passing through a processing unit 5.
