Abstract

The utility model provides an optical size measuring instrument, which comprises a control unit, a measuring station, a measuring tooling arranged on the measuring station, and two or more than two image measuring instruments positioned above the measuring station and used for detecting objects on the measuring tooling. The image measuring instruments are electrically connected with the control unit, can flexibly adapt to objects with different sizes, and in measuring process, a user need not to move the image measuring instruments or the objects to be measured, thereby saving time, and improving measuring efficiency. By adopting the two or more than two measuring tooling, measuring continuity is further improved, and the optical size measuring instrument achieves higher measuring efficiency.

Description

The optical dimensions measuring instrument

[technical field]

The utility model relates to optical measuring technique, especially a kind of optical dimensions measuring instrument that improves efficiency of measurement.

[background technology]

In electron trade, it is many that the characteristics of production are tending towards kind at present, and few in batches, production line will be produced several type products every day sometimes.Under this allegro mode of production, if the test item of quality is a lot, the sampling observation rate is 100%, then the qualitative control means is proposed very high requirement.

Existing solution is to adopt flexible 2～3D image measuring, as: the CNC300 of OPG company, Switzerland TesaVisio 200 type hand image measurers are at the vital part of different products, work out corresponding process of measurement, move the correlation parameter that this process of measurement can detect part.Call different programs, just can measure different parts.

The deficiency of this surveying instrument is: measurement range is little, when workpiece exceeds measurement range, need the video camera XY worktable of workpiece (or bear) to move to the different measuring position, because mechanical motion is arranged, cause efficiency of measurement decline, can not adapt to the detection requirement of producing fast pace, high-level efficiency, 100% sampling observation rate.

[utility model content]

Technical problem to be solved in the utility model provides a kind of optical dimensions measuring instrument that improves efficiency of measurement.

For solving the problems of the technologies described above, the utility model provides a kind of optical dimensions measuring instrument, comprises control module, measures station, can place the measurement frock of measuring station; Also comprise being positioned at two or more image measurers of measuring the station top, being used to detect the measured object on the described measurement frock, image measurer and described control module electrically connect.When the measured zone of measured object was within the measurement range of an image measurer, image measurer work of control module control got final product; When the measured zone of measured object exceeded outside the measurement range of an image measurer, control module was controlled two or more image measurer work, measures needs to satisfy.

On this basis, further:

The quantity of measuring frock is two or more, measures frock and can move to the measurement station by turns.Like this, measure frock when one of them and be in when measuring station and measuring, other measures frock can carry out material loading or discharging, has shortened the stand-by period.

The beneficial effects of the utility model are: two or more image measurers are set, can adapt to the measured object of different size neatly, without movable image measuring instrument or measured object, saved the time in the measuring process, efficiency of measurement is improved.By adopting two or more to measure frock, further improved continuity of measurement, have higher efficiency of measurement.

[description of drawings]

Below by embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail:

Fig. 1 is that the master of a kind of embodiment of the utility model looks synoptic diagram;

Fig. 2 is the schematic perspective view of two image measurers 1 in the optical dimensions measuring instrument shown in Figure 1;

Fig. 3 is that synoptic diagram is looked on the right side of two image measurers 1 in the optical dimensions measuring instrument shown in Figure 1.

[embodiment]

Fig. 1, Fig. 2 and Fig. 3 show a kind of embodiment of the present utility model.

As Fig. 1, Fig. 2 and shown in Figure 3, this optical dimensions measuring instrument comprises control module (not shown in the accompanying drawing), two image measurers 1 and two measurement frocks 2, two image measurers 1 and two measurement frocks 2 electrically connect with control module respectively, control module control image measurer 1 and the work of measuring frock 2.

Measure frock 2 for two and be used for carrying measured object.When the measured zone of measured object was within the measurement range of an

image measurer

1,1 work of image measurer of control module control got final product; When the measured zone of measured object exceeded outside the measurement range of an image measurer 1, two image measurers 1 of control module control were worked simultaneously, measure needs to satisfy.So just can once finish the measurement of measured object, and, shorten to every 2-1.8sec by every original 15-20sec the measuring period of a measured object, greatly improve efficiency of measurement without movable image measuring instrument 1 or measured object.

This optical dimensions measuring instrument has disposed two simultaneously and has measured frock 2, measuring frock 2 is installed on the mechanical guide rail, as shown in the figure, measure below that frock 2 is positioned at two image measurers 1, be in the measurement station for one, another measures frock 2 at last/blanking state, measure like this and on/blanking can carry out simultaneously.A frock is finished to measure and is withdrawn, and another enters the measurement state at once again. the measurement stand-by period in the middle of having shortened.

During concrete enforcement, the image measurer of greater number can also be set as required and measure station, to adapt to the requirement of workpiece calibration scope and efficiency of measurement.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
