Problems solved by technology

[0003] However, due to the different actual working conditions, in terms of workpiece positioning accuracy, some have relatively high requirements for workpiece positioning accuracy, while others have relatively low requirements. Different workpieces have different positioning accuracy, and even have relatively large differences. , for some workpieces placed on the turntable of the worktable, the angle error of 5 degrees or even 10 degrees will not affect its handling
[0004] Therefore, in some applications, it is not necessary to use a catenary workpiece handling table with too high positioning accuracy. To some extent, too high accuracy is also a waste
In view of this, for example, the above-mentioned patent document CN102633114A adopts a servo motor to obtain relatively high control accuracy, relatively speaking, its cost is relatively high, and the use of forward and reverse control requires frequent start and stop of the servo motor, which is likely to cause the servo motor overheat
[0005] For forward and reverse control, for example, the reducer used for rotation is usually a gearbox, and there is a gap between the gears, and the conversion of forward and reverse will produce errors.
[0006] In addition, in view of the fact that the above-mentioned patent document CN102633114A adopts visual recognition, or a workpiece positioning method based on image processing, relatively speaking, the cycle from image shooting to recognition calculation is relatively long, and the efficiency is relatively low

Embodiment Construction

[0034] Regarding the reflective photoelectric sensor 18, also known as a reflective photoelectric switch, the common reflective infrared photoelectric sensor is a small photoelectric component that can detect changes in the light intensity it receives. In the early stage, it was used to detect whether the object was sensed. It is composed of an infrared emitting tube and an infrared receiving tube. Its emission wavelength is 780nm-1mm. The emitter has a calibration lens to focus the light on the Receiver, the receiver out cable connects this unit to a vacuum tube amplifier.

[0035] The detection object is when it enters the gap between the slotted switch and the block light path between the emitter and the detector, when the object approaches to the interrupter, the light collected by part of the receiver is reflected from the object to the photoelectric element above. It uses the object to block or reflect the infrared beam, and detects the presence or absence of the object ...

Abstract

The invention discloses a workpiece carrying bench on a catenary, comprising: a work rack; a turnplate mounted on the work rack through a rotary support; a fixture mounted on the turnplate and used to concentrically position and clamp the workpiece with the turnplate; a drive device that drives the turnplate to adjust its rotational angle; a first reflecting photoelectric sensor; a second reflecting photoelectric sensor; a third reflecting photoelectric sensor. The carrying bench according to the invention is relatively low in manufacture cost and has high positioning precision.

Description

technical field [0001] The invention relates to a workbench for conveying workpieces on catenary lines. Background technique [0002] The catenary workpiece handling workbench disclosed in Chinese patent document CN102633114A is the first catenary workpiece handling workbench proposed by the applicant, which solves the problem of the workpiece being transported or placed on the workbench. Non-ideal problems, so that the handling equipment can accurately hang the workpiece on the catenary production line. [0003] However, due to the different actual working conditions, in terms of workpiece positioning accuracy, some have relatively high requirements for workpiece positioning accuracy, while others have relatively low requirements. Different workpieces have different positioning accuracy, and even have relatively large differences. , for some workpieces placed on the turntable of the worktable, the angle error of 5 degrees or even 10 degrees will not affect its handling. ...
