A kind of silica crucible physical dimension pick-up unit
Technical field
The utility model belongs to testing tool, relates in particular to silica crucible physical dimension automatic checkout equipment.
Background technology
In the silica crucible technological process of production, crucible detects to have manually finishes major defect: the manually-operated error is large, and measuring accuracy is not high, and the recording process misuse rate is high at present; Labour intensity is large, and carrying makes a big impact to the crucible quality.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this utility model has provided a kind of efficient automatically silica crucible physical dimension pick-up unit.
Technical scheme: for achieving the above object, the utility model is by the following technical solutions: a kind of silica crucible physical dimension pick-up unit, comprise laser micrometer, laser displacement sensor, manipulator positioning mechanism, travelling belt and PLC control system, wherein: described travelling belt is used for transmitting silica crucible; Described laser displacement sensor is fixed on manipulator positioning mechanism, and is used for measuring the height of silica crucible; Described laser micrometer is for the thick and base thickness of external diameter, wall thickness, arc of measuring silica crucible; Described PLC control system receives respectively the measurement data of laser displacement sensor and laser micrometer, and the control manipulator positioning mechanism positions, control simultaneously travelling belt and carry next silica crucible to be measured, control laser displacement sensor and laser micrometer are measured.
As preferably, described PLC control system adopts Siemens S7-300 series of PLC control system.
As preferably, described laser micrometer is provided with the thick measurement point of arc, base thickness measurement point, outside diameter measuring point and wall thickness measuring point simultaneously.
Beneficial effect: compared with prior art, the utlity model has following advantage: 1. all control procedure is finished by PLC control, raises the efficiency and security.2. the signal in the whole control procedure can collect the HMI picture by PLC, handled easily control and plant maintenance.3. measure and finished by high precision laser displacement sensor and laser micrometer, precision is high, and error is controlled at 10 μ m.4. travelling belt transmission point is accurately located by optoelectronic switch, has guaranteed the precision of measuring.5. manipulator locating device gets three-dimensional registration, can guarantee the accuracy of the solid space of each measurement point.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, laser micrometer 1, laser displacement sensor 2, manipulator positioning mechanism 3, the thick measurement point 4 of arc, base thickness measurement point 5, outside diameter measuring point 6.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of silica crucible appearance detection apparatus, the PLC control system that comprises the S7-300 series that laser micrometer, laser displacement sensor, manipulator positioning mechanism, travelling belt and employing Siemens produce, wherein: described travelling belt is used for transmitting silica crucible; Described laser displacement sensor is fixed on manipulator positioning mechanism, and is used for measuring the height of silica crucible; Described laser micrometer is for the thick and base thickness of external diameter, wall thickness, arc of measuring silica crucible; Described PLC control system receives respectively the measurement data of laser displacement sensor and laser micrometer, and the control manipulator positioning mechanism positions, control simultaneously travelling belt and carry next silica crucible to be measured, control laser displacement sensor and laser micrometer are measured.
This equipment is finished whole equipment control automatically by PLC, reaches the people to the monitoring of automatic control process by man-machine picture simultaneously.The crucible measured zone position that travelling belt is determined is located by photoelectric sensor, crucible is sent to the detection position of appointment, then by manipulator locating device the sampled point that laser displacement sensor corresponds to the technological requirement detection is measured, the data feedback of measuring the most at last is to PLC, show by peripheral display system, and data recording is filed.
