Locating device and locating method

Abstract

The invention discloses a locating device which comprises an adhesion manipulator and a locating clamp. The adhesion manipulator is provided with a rotating shaft, a rotating arm and two disc suction heads, wherein the rotating arm is vertically installed on the rotating shaft, and the disc suction heads are installed at both ends of the rotating arm and have a same distance with the axis of the rotating shaft. The locating clamp comprises a clamp main part and a clamp secondary part, wherein the clamp main part is provided with an installation hole corresponding to the rotating shaft, station holes are respectively arranged at both ends of the clamp main part, the distance between each station hole and the center of the installation hole is equal to the distance between each disc suction head and the axis of the rotating shaft, and the clamp main part is in matching connection with the clamp secondary part to fix the clamp main part on the rotating shaft and relieve fixation. Because the locating clamp has the advantages of simple structure, convenient use, low cost and strong universality, the horizontal position and the symmetry of the disc suction heads of the adhesion manipulator is regulated by using the locating clamp with simple and rapid regulation, low cost and high regulation accuracy. In addition, the invention also discloses a locating method.

Description

technical field [0001] The invention relates to a positioning device and a positioning method, in particular to a positioning device and a positioning method suitable for aligning a bonding manipulator in a CD production line. Background technique [0002] The optical storage medium has developed from CD (Cmpact Disc, Laser Disc) to DVD (Digital Versatile Disc, Digital Versatile Disc), to the current BD (Blu-ray Disc, Blu-ray Disc). To reduce the size of the information record, this requires that the wavelength of the reading and recording light used must be gradually shortened, while the numerical aperture (NA) value of the reading objective lens is continuously increasing, so the wavelength used by the optical storage medium (disc) From CD's 780nm to DVD's 650nm, to BD (Blu-ray Disc), the blue laser with a wavelength of 405nm is used, and the numerical aperture (NA) value of the objective lens is from 0.45 of CD to 0.6 of DVD, to BD (Blu-ray Disc). ) reached an NA value o...

Problems solved by technology

In the bonding device, it is often necessary to use the bonding manipulator to transfer the substrate to the bonding station. The bonding manipulator transfers the substrate mainly through the suction cup head of the bonding manipulator to absorb the substrate and rotate it. Therefore, the bonding manipulator moves The accuracy of the suction cup head and the level and symmetry of the suction cup directly affect the quality of the production process, especially the symmetry of the suction cup head. If the suction cup head is asymmetrical, it will cause the deviation of the substrate and seriously affect the bonding of the two substrates; therefore , the production system needs to adjust the horizontal position and symmetry of the suction cup head of the bonding manipulator before operation. The symmetry of the suction cup head is adjusted. This adjustment depends heavily on the technical level and proficiency of the operator. The positioning accuracy is low, time-consuming and laborious, and it is difficult to meet the accuracy requirements of production.
