  • Patent number: 10792720
    Abstract: A hemming device includes an anvil for placing a work, a presser material handling portion, a conveyance robot, and a roller hemming robot. The anvil includes an anvil main body portion, a positioning device, a gripping device, and a device-side ATC device to be attached to and detached from a conveyance-robot side ATC device. The presser material handling portion includes a frame portion having a shape corresponding to a shape of the work, a positioning device, a gripping device, a presser provided to press the inner panel at a position at which the presser does not interfere with a final shape, and a device-side ATC device to be attached to and detached from the conveyance-robot side ATC device. With this configuration, processing time is reduced and replacement operation of the anvil is simplified, and therefore productivity is improved.

  • Patent number: 7575408
    Abstract: Plural wok pairs composed of a plurality of works are stored in work storing means. A movable sensor 45 fitted to a conveyance robot 5 detects the position of one of the work pairs in the work storing means, and the work gripping means 25 takes out a plurality of works at one time from the work storing means. One of the plurality of works is held temporally by temporal work holding means 6 or 7 while the other work is conveyed to a jig Y. In the course of conveyance, a fixed sensor 63 detects the relative positional relationship between the work and the work gripping means 25. If the relative positional relationship deviates from the regular positional relationship, the movement of a robot arm 31 is corrected.

  • Patent number: 5525840
    Abstract: A semiconductor device has an alignment mark formed as a diffraction grating which comprises a plurality of unit markers arranged so that the period P of the diffraction grating is 8 .mu.m. The length d.sub.1 of each unit marker in the scanning direction of a laser beam is 4 .mu.m while the length L thereof in a direction perpendicular to the scanning direction is 4 .mu.m. Each unit marker comprises nine unit segments each of 0.8 .mu.m.times.0.8 .mu.m in size and arranged in an array of 3.times.3. Submicron openings constituting an unit segment has a small size for sufficiently filling the openings with deposited metal. An accurate alignment can be obtained by the alignment mark in an optical stepper for manufacturing semiconductor devices.

  • Patent number: 5237393
    Abstract: In a reticle, a small pattern including a transparent portion and a large pattern including a light shielding portion are provided on a straight line in parallel to an x or y direction of the pattern forming area in the vicinities of crossing portions of opposite two sides of the pattern forming area with the straight line. A wafer is exposed with this reticle such that centers of the small pattern and the large pattern are overlapped. By measuring relative deviation of the center positions, the in-field error is calculated.
