Description

CCD laser measurement sensor

Technical Field

The utility model relates to a detect technical field, in particular to CCD laser survey sensor.

Background

Two displacement sensors can be purchased and used in the market at present, one is a huge-head manufacturer for manufacturing sensors abroad, such as Keynes, Panason and Onglong company, the product technology is a CMOS image sensor or a CCD light transmission type displacement sensor, although the precision is high, the selling price is high, and the supply channel is few; the other domestic sensor is a linear displacement sensor resistance ruler, has a small application range, is mainly used for a screw machine of an injection molding machine, and cannot be widely applied to industrial automation.

SUMMERY OF THE UTILITY MODEL

According to the not enough of above prior art, the utility model provides a CCD laser measurement sensor.

In order to solve the technical problem, the utility model provides a pair of CCD laser survey sensor, including shell, light source, optic fibre, reflector, optical lens and linear CCD, the light source is fixed in the upper left corner position department of shell, and the right side position department at the light source is fixed to the optic fibre level, the reflector is including two, is the fixed right-hand at optic fibre of the fixed setting of the uncovered form of big right side, the vertical left side position department of fixing at the reflector in below of optical lens is provided with between optical lens and the linear CCD and measures the region, and the measured object is placed in measuring the region, linear CCD installs in measuring regional left side projection position department.

Preferably, the linear CCD further comprises a micro MCU, an OLED display screen and a communication bus, wherein the linear CCD is used for processing and analyzing through the internal micro MCU, displaying data on the OLED display screen and sending the data to the outside through the communication bus.

Preferably, the light source is an LED light source.

The utility model discloses an gain effect: the utility model discloses a CCD laser measuring sensor, which has small volume, and can detect the upper and lower edge positions of an object and the width of the object in real time by using a correlation CCD light source; can be applied to: 1. the two groups of displacement sensors can position the positions of plane objects such as glass, steel plates and the like by positioning the objects; 2. measuring the diameter of a moving object, such as the shaft diameter of a screw nut; 3. the center distance of the object is measured, and after the center position is recorded, the eccentric measurement is realized to achieve the positioning effect.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural diagram of the present invention;

in the figure: 1 casing, 2 light sources, 3 optical fibers, 4 reflectors, 5 optical lenses, 6 measurement areas and 7 linear CCD.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

In this embodiment, as shown in the figure, the CCD laser measurement sensor provided in this embodiment includes:

a housing 1;

the light source 2 is fixed at the upper left corner of the shell 1, and the LED light source can be specifically selected;

the optical fiber 3 with the hole is horizontally fixed at the right side position of the light source 2;

the two reflectors 4 are fixedly arranged on the right side of the optical fiber 3 in an open shape with a large left and a small right;

an optical lens 5, the optical lens 5 being vertically fixed at a left side position of the lower mirror 4;

a measuring region 6, wherein the measuring region 6 is positioned between the optical lens 5 and the linear CCD7 and is used for placing a measured object;

a linear CCD7, the linear CCD7 being installed at a left side projection position of the measurement region 6;

the linear CCD is processed and analyzed through the internal micro MCU, data are displayed on the OLED display screen, and the data are sent out through the communication bus.

The working principle is as follows: the light source 2 of this embodiment forms relatively stable pointolite through 3 round holes of optic fibre, passes through the reflection of two surface reflectors 4 again, sees through optical lens 5 and forms the parallel light, and the measuring object sets up in measuring region 6, shelters from the parallel light, and linear CCD7 will measure the position and the width of sheltering from, linear CCD7 handles the analysis and with data display on the OLED display screen through inside miniature MCU to outwards send data through communication bus.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
