Automatic alignment method and device using optical alignment

Abstract

The invention belongs to the field of manufacturing and processing, and particularly relates to an automatic alignment method and device using optical alignment. The device comprises a workpiece to be aligned and an optical transceiver module. The optical transceiver module comprises a first transmitting end, a second transmitting end, a first receiving end and a second receiving end which are all arranged on the same horizontal plane. A first reference point, a second reference point, a third reference point and a fourth reference point are calibrated on the workpiece. The first reference point, the second reference point, the third reference point and the fourth reference point are all located on a horizontal plane. The workpiece is rotated on the horizontal plane, a light beam between the first transmitting end and the first receiving end passes through the first reference point and the second reference point, a light beam between the second transmitting end and the second receiving end passes through the third reference point and the fourth reference point, and alignment operation is completed. Optical automatic alignment is adopted, the alignment efficiency and precision are improved, and abrasion of the workpiece in the alignment process is reduced.

Description

technical field [0001] The invention belongs to the field of manufacturing and processing, and in particular relates to an automatic alignment method and device using optical alignment. Background technique [0002] Alignment operations are involved in the automated operation of many industries. For example, the automatic assembly of workpieces with positioning requirements currently adopts mechanical alignment. The alignment speed is slow, the error is large, and the alignment is not accurate, and multiple tests and tests are required. Correction. After alignment, additional sensors are required to transmit the alignment results to the logic controller. For example, the front part of construction engineering drill bits on the market needs to be welded with a hard alloy sheet, which is fixed to the head of the drill bit by welding such as brazing to resist wear. At present, most enterprises manually put the cemented carbide sheet into the groove of the drill pipe head for ...

AI Technical Summary

Problems solved by technology

At present, most enterprises manually put the cemented carbide sheet into the groove of the drill pipe head for welding, which is slow and inefficient.

Some enterprises have developed welding automation equipment, but frequent failures occur in the process of use, all of which are caused by failures in the alignment process.

The alignment process adopts mechanical alignment. The main problem is that the alignment error is large, the stability is poor, and it is difficult to detect accurately. After the alignment fails, the automatic operation is automatically interrupted, which seriously affects the operation of the equipment and greatly reduces the production output.
