AOI lifting working platform

Abstract

The invention discloses an AOI lifting working platform which comprises a machine body and a horizontally-arranged working platform body. An X-axis guide rail and a Y-axis guide rail which are vertically arranged are arranged below the working platform body, the Y-axis guide rail is arranged on the X-axis guide rail, the working platform body is arranged on the Y-axis guide rail, a horizontal supporting platform is further arranged below the X-axis guide rail, one side of the horizontal supporting platform is connected with a nut seat, and the other side of the horizontal supporting platform is connected with a sliding block. A screw hole is vertically formed in the nut seat, a screw rod is vertically arranged on the machine body, the screw rod is inserted into the screw hole and is in threaded connection with the screw hole, and the lower end of the screw rod is in transmission connection with an output shaft of a driving motor. A sliding rail is vertically laid on the machine body, and the sliding rail and the sliding block are connected in a relative sliding mode. The height of the AOI working platform can be adjusted, a PCB is in smooth transition from a backflow furnace to AOI, focal setting is carried out in cooperation with a camera, focusing can be achieved fast and accurately, the high definition of a picture is guaranteed, and the AOI lifting working platform is suitable for being used on AOI working platforms, and has the advantages of being simple in structure and high in control precision.

Description

technical field [0001] The invention relates to a liftable workbench, in particular to an AOI liftable workbench, which belongs to the technical field of optical detection equipment. Background technique [0002] The full name of AOI is full-automatic optical detector. Its main function is to replace the manual search for various appearance defects of PCB boards. It can be efficient, accurate, time-saving, and cost-saving. In the PCB board production line, AOI passes The barge is connected to the reflow oven for producing PCB boards. There are various forms of applying AOI technology in SMT, but the basic principle is the same, that is, the image of the object under test is obtained by optical means, and the illumination image of the object under inspection is generally obtained through a sensor (such as a camera) and digitized, and then in a certain way Comparing, analyzing, inspecting and judging is equivalent to automating and intelligentizing manual visual inspection. ...
