Large assembly alignment platform structure

Abstract

The invention discloses a large assembly alignment platform structure. The large assembly alignment platform structure is provided with servo driving components, a splicing assembly platform and passive load bases; after upper sliding blocks on the servo driving components are driven, active load bases and detection blocks arranged on the sides of sliding blocks in a locking mode are moved in theX-axis direction and the Y-axis direction, and the splicing assembly platform is driven to rotate by the theta angle in the X-axis direction and the Y-axis direction; the moving stroke of the splicingassembly platform is detected through detection bases for platform alignment; the active load bases and the multiple passive load bases can be used as passive support points of the lower side of thesplicing assembly platform, so that all splicing points of the splicing assembly platform have the support points; the load force of the support points of the splicing assembly platform is uniform, sothat the splicing assembly platform is assembled according to the platform size required by a user; the splicing assembly platform can be assembled quickly, and is easy to convey; and the large assembly alignment platform structure is applicable for manufacturing and inspection equipment of various liquid crystal display panels, semiconductor manufacturing and inspection setting and screen printing equipment or printed circuit board manufacturing and inspection equipment, and alignment movement of the alignment platform is achieved.

Description

technical field [0001] The invention relates to a large-scale assembly alignment platform structure. Background technique [0002] In various liquid crystal panel manufacturing, inspection equipment, semiconductor manufacturing, inspection setup, screen printing equipment or printed circuit board manufacturing, inspection equipment, it is necessary to use the alignment platform for alignment movement and other procedures, and in order to improve precision, except for the X-axis , Y-axis movement, in addition to the XY-axis movement achieved by telescopic elements, it should also have theta angle movement function, in order to achieve high precision requirements. [0003] However, the known large-scale alignment correction alignment platform structure still has the following deficiencies. The center of the alignment alignment platform is completely suspended in the air, and there is no support point, so that the load force at this place will be slightly insufficient, and it i...

[0003] However, the known large-scale alignment correction alignment platform structure still has the following deficiencies. The center of the alignment alignment platform is completely suspended in the air, and there is no support point, so that the load force at this place will be slightly insufficient, and it is easy to fall When the heavy object is put down, the correction alignment platform will deform from the suspension, which will affect its alignment accuracy; and it only uses slide rails or linear guide rails to connect the base and the offset seat, which will make the slide rail or Linear guide rails are not resistant to bearing loads, which will damage the slide rails or linear guide rails, and cannot be assembled according to the size of the platform required by the user, and cannot meet the needs of fast assembly and convenient transportation.
