Description

Technical Field

[0001] The present invention relates to the field of laser light source scanning technology, specifically to a 3D camera and a laser light source high-speed scanning device. Background Art

[0002] A 3D digital camera is a digital camera that allows people to enjoy stereoscopic images or animations with their naked eyes. The birth of 3D digital cameras means that people can enjoy the effects of stereoscopic images with their naked eyes without the use of professional glasses. 3D digital cameras are generally equipped with two lenses so that they can reproduce stereoscopic images. In addition, there is technology to realize the external 3D lens of a mobile phone, transforming it into a 3D camera, which can realize the three-dimensional data acquisition of images and videos for three-dimensional image shooting and live broadcasting;

[0003] Laser light source is an electric light source that uses excited particles to emit light under stimulated radiation. It is a coherent light source. Since TH Maiman in the United States made the ruby ​​laser in 1960, there have been hundreds of types of laser light sources, with output wavelengths ranging from short-wave ultraviolet to far infrared.

[0004] Laser light sources can be divided into four types according to their working materials (also called activated materials): solid laser sources (crystals and neodymium glass), gas laser sources (including atoms, ions, molecules, excimers), liquid laser sources (including organic dyes, inorganic liquids, chelates) and semiconductor laser sources.

[0005] After searching, it was found that the application document with application number "CN201821819713.0" discloses an XZ long-stroke high-speed scanning device, in which the macro motion platform performs horizontal motion in the X-axis direction on the macro motion base, and the inclined slider force-enhancing mechanism converts the horizontal macro motion of the macro motion platform in the X-axis direction into the vertical macro motion in the Z-axis direction. Piezoelectric ceramics and high-steel springs cooperate with each other, and piezoelectric ceramics can achieve nanometer-level precision control. By controlling the tiny deformation of the high-steel spring, high-precision displacement compensation of the micro motion platform can be achieved, and through the vibration reduction function of the piezoelectric ceramics, a reverse motion force is applied to the micro motion platform, which can achieve rapid vibration reduction of the micro motion platform and ensure the stable and rapid operation of the micro motion platform. The technical problem that the existing precision scanning instrument adopts a flexible hinge superposition mechanism, which will cause a large error to the motion platform, and the piezoelectric ceramics will generate a large vibration when driving the flexible hinge, making the motion stability of the motion platform low, is solved. This kind of 3D camera and laser light source high-speed scanning device still has the following defects in actual use:

[0006] 1) The traditional 3D camera itself cannot perform more accurate and free scanning analysis, which leads to the reduction of accuracy and freedom in the scanning detection of the laser light source of the camera. It can only be used as a functional scanning movement at a certain point or in a certain direction of the object being illuminated, which greatly reduces the efficiency and stability of the scanning detection of the scanned object. In addition, it is subject to the flexible restriction of the detection angle of its own structure. In the stage of driving the camera bracket to move, the comparison document can only complete "the macro motion platform performs horizontal movement in the X-axis direction on the macro motion base, and the inclined slider force amplification mechanism performs the horizontal macro movement of the macro motion platform in the X-axis direction, and its own angle replacement can only be converted into a vertical macro movement in the Z-axis direction". Obviously, the range of mobile scanning is relatively poor and not flexible enough, which is not enough to achieve 360° scanning of the scanned object;

[0007] 2) Nowadays, in order to achieve 3D scanning of workpieces, it is necessary to manually hold the 3D camera on the surface. Due to the hand-held operation, the workpiece can only be placed on the ground. When manually operating the 3D camera for scanning, the flexibility of workpiece scanning detection is generally reduced. Due to the hand-held operation, the body position can only be moved manually to ensure that the scanned object can be accurately detected, which has caused a considerable impact.

When rotating, the rotation speed is controlled to ensure that the workpiece to be inspected and the cross brace do not have relative displacement;

[0083] The workpiece to be scanned is placed on the surface of the annular sleeve cover 59;

[0084] Based on the sensing structure of the ultrasonic detection structure, the corresponding workpiece to be scanned is further placed on the surface of the cross support rod 58, and is placed according to the cross state of the cross support rod 58;

[0085] In order to better perform detection scanning, the user first turns on the sleeve effect of the drive base 53 and the corresponding transmission sleeve 55 based on the operation panel 499 on the support bracket 498 to control the upper end of the transmission drive shaft 56 to realize drive rotation, and based on the sleeve effect of the transmission sleeve 55 at the top of the drive sleeve seat 54 at the lower end, the sleeve state of the cross support rod 58 on the transmission drive shaft 56 and the annular sleeve cover on its outer ring is further realized to realize transmission-type drive, so that multiple ultrasonic detection structures are turned on to realize rapid detection scanning. In the detection scanning stage, after rotating, the ultrasonic detection of the object placed on the annular sleeve cover 59 can be completed more conveniently. The scanned result after the detection is completed is then fed back to the display screen by the ultrasonic wave;

[0086] Step 2: further sensing is required, which requires the use of an external limiting base 49;

[0087] At this time, the user controls the front-end driving structure of the assembly base 495 to control the transmission structure of the driving sleeve 492 after the brushless motor 493 on the outer wall and the motor connecting seat 494 on the side wall are limited, so as to adjust the flipping of the transmission connecting rod 491. In the flipping stage, the user controls the driving scheme on the transmission roller 43 according to the driving stage on the limiting base 49 and the transmission base 48 at the end position to adjust the up and down flipping of the driving motor 42 and the transmission roller 43, thereby realizing the flipping of the driving motor 42 on the outer side of the motor seat 41, and then splicing it with the outer frame structure on the linear frame 31 installed at the output end of the motor, and combining it in the splicing state, so that under the synchronous driving action of the stepping motors 33 on both sides, the sliding structure 32 is controlled to achieve forward and backward displacement along the Y-axis direction of the linear frame 31;

[0088] Its purpose is to determine the structure between the scanning area and the scanned area to slide, and then slide to the specified position around the linear frame 31 to be fixed;

[0089] Step 3: Then control the horizontal sliding end of the middle part to approach the middle area;

[0090] When approaching, in order to fine-tune the deflection degree of the 3D lens recognition surface 193 to smoothly scan the workpiece (rail or track wheel):

[0091] Phase change of lens displacement: after the driving screw rod 16 rotates, the sliding sleeve 17 will also translate up and down along the rod body embedded in the sleeve;

[0092] At this time, the 3D lens recognition surface 193 will synchronously complete the displacement in the Y-axis direction (for short-distance focusing, when the descending position is low enough and the fine focusing has not been completed, this method can be used)

[0093] The up and down flipping of the lens is based on: the synchronous flipping of the transmission seat 191 and the transmission motor 19;

[0094] The lens of the 3D lens recognition surface 193 will flip up and down according to the position of the lens mounting slot 184, the purpose of which is to achieve the lens's short-range optical downward and upward scanning shooting;

[0095] In the specific flipping stage, the user implements the adaptation installation based on the lens assembly groove 184. In the installation stage, the user then controls the support function of the U-shaped base 185 to control the position of the spherical recording end 192 at the bottom to achieve flipping. According to the driven rotation function of the transmission motor 19 on the transmission seat 191, the 3D scanning of the spherical recording end 192 is further achieved. In the process of the initial scanning, the driven rotation of the annular sleeve cover 59 is better completed. In the rotation stage, the angle of the scanned object can be further adjusted to make the scanning structure contact with the lens structure of the 3D camera bracket 11 more detailed.

[0096] Based on the ultrasonic transceiver and the spherical recording end 192 of the spectrum analyzer, a displacement mechanism for sliding displacement is also provided on the outside. The displacement mechanism is used to adjust the position of the scanning end. The infrared laser positioning module and the ultrasonic scanning head are used to complete the three-dimensional scanning perception of the object workpiece, and build a 3D model of the object. Finally, it is connected with the scanning modeler of the back-end imaging to achieve the laser three-dimensional model construction, which improves the scanning speed of the physical workpiece. In addition, the mutual support of laser and ultrasonic wave makes the precision of the scanned model better.

[0097] In this process, the user further adjusts the batch sensing between the infrared bearing base 63 and the control base 64 according to the supporting function of the corresponding bearing side plate 61 and the corresponding placement plate 62, and mobilizes the signal image transmitted by the scanning surveying instrument 68. After achieving the feedback display status on the signal image, the information data generated by the real-time scanning structure of the front scanning head 67 is further fed back to the specific perception stage of the scanning head 67, thereby further achieving signal scanning detection. Based on this, the technical solution can also be supplemented with an external modular ultrasonic searchlight structure and the mobilization status of the displacement flipping mechanical arm used to adjust the searchlight structure, thereby further achieving unified perception of the scanning head 67 and realizing signal scanning.

[0098] When the stepper motor 33 and the pulley 312 are too far apart, one solution is to use the output end of the stepper motor 33 to mobilize the pulling detection caused by the forward and backward movement of the pulley 312. At this time, the output end of the stepper motor 33 will synchronously drive the pulley 312 to rotate. During the rotation process, the rotation of the pulley 312 in the rotation stage will move forward and backward along the surface of the linear frame 31.
