Title: Laser marking device
Inventor: OKAWA HIROO
IPC: B23K26/00
Filed: 1988-09-30
Abstract: PURPOSE:To execute positioning of a work without pressing it by floating a ceramic work by air on flat parts which are inclined, carrying and positioning it on one base, assembling as one body each device of an optical system and inclining all of them. CONSTITUTION:In a work positioning part 4, a work is floated up by blowing out air from a hole made on a plane base. Since friction is small, when the base is inclined by about maximum 5-10 degrees, the work slides on the plane base 1, hits against a V-shaped stopper 4 of the end part of the base and stops. In this case, when a laser optical system 2 and a carrying part 5 which are positioned are also in parallel to the work, handling can be executed more easily, therefore, they are inclined. When the positioning part, the laser optical part and the carrying part are fixed onto one base 1 and inclined against the horizontal plane 6, accuracy between each part is obtained easily, and the assembly is also facilitated. In such a way, a work which is apt to be damaged can be positioned without pressing it.

Title: Method of mounting part onto multiple sheet printing board
Inventor: SASAKI HIDETOSHI
IPC: H05K1/02
Filed: 1990-09-14
Abstract: PURPOSE:To reduce or cut the process of inspecting reject marks of printing boards to reduce a period of time for mounting parts to printing boards by dividing a multiple of printing boards into a number of groups and by putting to unacceptable boards marks indicating the presence or absence of defective boards. CONSTITUTION:In order to know whether or not group A contains defective boards, an inspection apparatus 5 first checks the upper right corner of A1 board. If a reject mark 7 is found there, in order to know what printing boards are unacceptable in the A group the inspection apparatus 5 checks all the reject marks in the A group and finds A4 printing board defective. Next, the same inspection is applied to the B group, and if there is no reject mark on a B1 printing board, inspection of the B group is completed, information of the inspection done so far is sent to the control apparatus of the part mounter, and parts are mounted to all the printing boards inspected so far except the A4 printing board. Or although conventionally all the printing boards are totally checked for reject mark, since no inspection is carried out on the B group that has no reject mark, the inspection work time can be reduced as much as a skipped period of time.
