Description
Technical Field
The utility model relates to an inspection robot device field specifically is inspection robot light source camera lens and machine vision camera lens focus synchronous regulation device.
Background
Among the prior art, it all is the fixed lens focus of light to patrol and examine robot most adoption, and machine vision adjusts the focus alone, and its weak point lies in: the focal length of the light source fixed lens is more dispersed when an observation object is farther, the light condensing capacity cannot be adjusted, and the light are condensed when the observation object is closer, so that the irradiation range is too small. Therefore, in the process of machine vision zooming, when a required observation point changes in a large range, the corresponding focal length matching cannot be realized due to the light source, so that the observation position condition cannot be clearly and reliably seen.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a provide and patrol and examine robot light source camera lens and machine vision camera lens focus synchronous regulation device to solve the defect that exists among the prior art.
The utility model provides an above-mentioned technical problem's technical scheme as follows:
a focal length synchronous adjusting device for a light source lens and a machine vision lens of an inspection robot comprises a lamp holder, a lampshade top plate and a lamp outer cover, wherein the lampshade top plate is fixed at the front end of the lamp holder, a convex lens is fixed on one side, facing the interior of the lamp holder, of the lampshade top plate, a linear motor is arranged on the outer side of the rear end of the lamp holder, an output shaft of the linear motor penetrates through the center of the lamp holder to enter the interior of the lamp holder, and a light emitting source is connected to the top end of; the convex lens is fixed at the center of the top plate of the lampshade through a trapezoid groove support, and the circle center of the convex lens and the output shaft of the linear motor are coaxial;
furthermore, two ends of the lamp housing are respectively sleeved outside the lamp holder and the lampshade top plate;
furthermore, a power line hole is formed in the rear end of the lamp holder, and a power supply line enters the lamp holder to supply power to the luminous source;
the utility model has the advantages that: the synchronous electric adjustment of the lens focal length of the machine vision and the lens focal length of the light source is realized, the simultaneous change of the two focal lengths can match the optimal light source effect and the most appropriate machine vision imaging effect for the same observation point.

FIG. 2 is a schematic sectional view taken along line A-A of FIG. 1;
FIG. 3 is a schematic cross-sectional view taken along line B-B of FIG. 1;
the reference numerals are explained below:
1. the lamp comprises a linear motor 11, a linear motor output shaft 2, a lamp holder 3, a lamp outer cover 4, a light emitting source 5, a convex lens 6 and a lampshade top plate;
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, the device for synchronously adjusting the focal lengths of the light source lens and the machine vision lens of the inspection robot comprises a lamp holder, a lampshade top plate and a lamp housing, wherein the lampshade top plate is fixed at the front end of the lamp holder, a convex lens is fixed on one side, facing the interior of the lamp holder, of the lampshade top plate, a linear motor is arranged on the outer side of the rear end of the lamp holder, an output shaft of the linear motor penetrates through the center of the lamp holder and enters the interior of the lamp holder, and a light emitting source is connected to the; the convex lens is fixed at the center of the top plate of the lampshade through a trapezoid groove support, and the circle center of the convex lens and the output shaft of the linear motor are coaxial;
more specifically, two ends of the lamp housing are respectively sleeved outside the lamp holder and the lampshade top plate;
more specifically, the rear end of the lamp holder is provided with a power line hole, and a power supply line enters the lamp holder to supply power to the luminous source;
the specific working process is as follows: as shown in fig. 2, the linear motor 1 is installed on the lamp holder 2, and the light source 4 is installed and fixed on the output shaft 11 of the linear motor, as shown in fig. 3, the light source 4 is inserted into the slot of the lamp holder 2; the lamp outer cover 3 is sleeved outside the lamp holder 2, and the convex lens 5 is placed at the top of the lamp holder 2 and fixed by the lamp cover top plate 6. When the linear motor 1 moves, the output shaft 11 of the linear motor extends or contracts, so that the luminous source 4 arranged on the output shaft 11 of the linear motor moves in a telescopic way by taking the slot of the lamp holder 2 as a guide rail; because the convex lens 5 is fixed on the lamp holder 2, according to the optical principle, the distance between the luminous source 4 and the convex lens 5 is changed to change the light focal length; when the inspection robot operates, the robot system controls the machine vision lens to zoom, and simultaneously, the robot system controls the linear motor 1 shown in fig. 2 to operate to a specified position, so that the focusing degree of the control light source can be matched with the lens focal length of the machine vision, and the optimal observation definition is finally obtained.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
