Description

Image acquisition box based on geneva mechanism and rack and worm mechanism

Technical Field

The patent relates to the technical field of lifting and steering of image acquisition equipment, in particular to an image acquisition box based on a geneva mechanism and a rack and worm mechanism, which can realize the lifting and steering function of the image acquisition process of an object to be detected.

Background

With the development of technologies such as computer vision recognition, image processing, hyperspectrum and the like, equipment for realizing image acquisition of an object to be detected is correspondingly developed. The lifting and steering are an important link of an image acquisition box based on a geneva mechanism and a rack and worm mechanism, and the lifting height, the steering angle and the steering accuracy of the lifting and steering device influence the acquisition of information of an object to be detected, so that the image acquisition accuracy of the object to be detected is influenced. At present, a plurality of pieces of image acquisition equipment for an object to be detected are not provided with a lifting and steering device, but a plurality of image acquisition devices or spectrometers are adopted to acquire information of the object to be detected, and the equipment is high in cost and poor in flexibility.

Disclosure of Invention

In view of the deficiency of prior art, this patent provides a simple structure, with low costs and easy lift, turn to, the image acquisition box of the operation of being convenient for.

In order to realize the above purpose, the technical scheme who takes is an image acquisition box based on geneva mechanism and rack and worm mechanism, including box, couple, LED lamp, image acquisition ware, objective table, driven geneva wheel, initiative driver plate, hand wheel, bevel gear, worm, rack, motor, frame and group round pin, its characterized in that: the LED lamp pass through the couple and install on the box, image collector fixed mounting is on the box, the objective table is placed in driven sheave top, driven sheave and initiative driver plate pass through the thumb pin clearance fit and install in the frame top, the hand wheel passes through the cooperation of a pair of bevel gear and the worm of perpendicular meshing, worm and rack toothing, the motor is fixed on the rack, rack fixed mounting is in the frame below, thumb pin fixed mounting is on the initiative driver plate.

The image acquisition box based on the geneva mechanism and the rack and worm mechanism is characterized in that: the objective table and the driven grooved wheel are both provided with center holes, and the center holes of the driven grooved wheel are through holes and are matched with a rotating shaft on the rack through flat keys.

The image acquisition box based on the geneva mechanism and the rack and worm mechanism is characterized in that: the driving drive plate and the rack are both provided with center holes, and the center holes of the rack are through holes and are matched with the rotating shaft of the motor through flat keys.

The beneficial effect of this patent is: simple structure, low cost, easy lifting and steering and convenient operation.

Detailed Description

The patent will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, an image acquisition box based on a geneva mechanism and a rack and worm mechanism comprises a box body 1, a hook 2, an LED lamp 3, an image acquisition device 4, an object stage 5, a driven geneva 6, a driving dial 7, a hand wheel 8, a bevel gear 9, a worm 10, a rack 11, a motor 12, a frame 13 and a poking pin 14.

According to the size of the object to be measured, the height of the object stage 5 is adjusted to enable the center height of the object to be measured to be approximately flush with the center height of the lens of the image collector 4, and the step of adjusting the height of the object stage 5 is as follows: the hand wheel 8 is rotated manually to drive the bevel gear 9 to rotate, the bevel gear 9 is driven to drive the worm 10, the worm 10 is meshed with the rack 11 to convert the rotary motion into the up-and-down linear motion, so as to realize the lifting of the objective table 5, when the central height of an object to be detected on the objective table 5 is approximately level with the central height of a lens of the image collector 4, the lifting is completed, the object to be detected is placed at the central position of the objective table 5, the illuminating lamp 3 and the image collector 4 are turned on, the image collector 4 acquires the image information of the object to be detected from the objective table 5 for the first time, the objective table 5 is sequentially adjusted for three times according to a 90-degree steering angle, the image collector 4 respectively acquires the image information of the object to be detected from the objective table 5 for the second time, the third time and the fourth time, after the image collector 4 acquires the information, the step of adjusting the steering angle of the object stage 5 to 90 degrees each time is as follows: the motor 12 transmits the driving dial 7 through the rotating shaft, the driving dial 7 enables the driven grooved pulley 6 to perform intermittent motion through the dial pin 14, the object stage 5 is further rotated, every time the driven grooved pulley 6 performs intermittent motion, the object stage 5 can rotate for 90 degrees once, and steering is completed.

In addition, in order to reduce damage to the object to be measured during the lifting and steering process of the lifting and steering device, a buffer damping material may be installed on the stage 5.
