- the mouth head 80 is attached to a holding frame 88 fixed to the frame 84 so as to be rotatable via a bolt 90, 90... It can be moved up and down freely by operating the handle 90a.
- a holding frame 88 fixed to the frame 84 so as to be rotatable via a bolt 90, 90... It can be moved up and down freely by operating the handle 90a.
- the mouth head 80 supported in a suspended state at the top of the frame 84 is interlocked with the rotary table 12 by an interlocking mechanism 92.
- the first and second planetary gears 98, 100 are respectively combined and connected to each other, and the first and second planetary gears 98, 100 are connected to the inspection equipment mounting table.
- the first and second planetary gears 98, 100 are supported on the inspection equipment mounting table 14 via the bearing body 104, so that the inspection equipment mounting table 14 is
- the first internal gear 94 and the second internal gear 96 can be rotated at a constant speed even when the rotary table 12 is rotated relative to the rotary table 12, so that the rotary table 12 and the mouth head 80 can be rotated. Can always be rotated synchronously.
- the rotation of the rotary input shaft 38 is performed by using the continuous rotary drive cam 40 and the swing rotary drive cam 42 to drive the rotary table 12 and the inspection equipment mounting table 14. Is converted into the continuous rotation of the rotary table 12 and the oscillating rotation of the inspection equipment mounting table 14, so that accurate motion can always be reproduced without any backlash in motion transmission.
- the positioning accuracy of the DUT 18 is improved, and image blurring and focusing are prevented. The gap can be eliminated.
- the CCD camera 32 and the transmission type detector 31 can be freely mounted on the inspection equipment mounting table 14 in the direction in which the inspection is desired, inspection of many items can be performed at one time.
- the row head holding the upper part of the object to be inspected is supported above the rotary table.
- an open space without any obstruction can be formed around the entire circumference of the rotary table and the mouth head.
- the rotary head is supported above the rotary table, which is above the transport path of the test object and does not interfere with the equipment structure, and serves as a dead space. It is not necessary to secure a special installation space for installing the head, and the head space can be effectively used to lay out the mouthpiece appropriately.
- the holding position of the object to be inspected by the low-end head can be raised and lowered. It is possible to inspect a plurality of different types of test objects having different heights with the same device.
- the interlocking mechanism includes first and second internal gears provided on a rotary table and a mouthpiece, respectively, and the first and second internal gears. It is composed of a pair of first and second planetary gears that are respectively coupled to the two-in-one primary gear and are connected to each other, and these first and second planetary gears are supported by the inspection equipment mounting table. Therefore, when the first internal gear is rotated together with the rotary table, the first planetary gear associated therewith and the second planetary gear connected thereto rotate, and the second planetary gear coupled to the second planetary gear further rotates. The internal gear also rotates, whereby the mouthpiece can be rotated in synchronization with the rotary table.
- first and second planetary gears are supported by an inspection equipment mounting table, even if the inspection equipment mounting table is of a fixed type, The first internal gear and the second internal gear can be rotated at the same speed, even if the rotary type is rotated relative to the rotary table as needed.
- the head can always be rotated synchronously.
- the rotary input shaft is driven to rotate to drive the continuous rotary drive cam and the swing rotary drive cam to rotate, and the rotary table is continuously rotated via the turret and the continuous rotary output shaft.
- the inspection equipment mounting table is reciprocated and rotated through the evening lett and the oscillating rotary output shaft, thereby continuously transporting the object to be inspected by the continuously rotating rotary table. Since the mounting table can be rotated synchronously with the rotary table when it is driven to rotate in the same direction as the rotary table, the non-contact type inspection equipment mounted on the inspection equipment mounting table is transported by the rotary table. It can be moved integrally with the object to be inspected in synchronism with the object to be inspected.
- the continuous rotation drive cam and the swing rotation drive cam are used to achieve continuous rotation of the rotary table and swing rotation of the inspection equipment mounting table. Accurate movement can be reproduced, and the rotational movement of both tables can be made high-precision, thereby significantly improving the inspection accuracy of inspection work that is affected by the accuracy of the rotational movement of both tables. Various excellent effects can be achieved.
