DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0032] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0033] like Figure 1-Figure 13 As shown, the present invention provides a visual acquisition device, including: a camera assembly 1, an angle adjustment mechanism 2, a stabilizer 3, and a mounting platform 4, wherein the camera assembly 1 is provided on one side of the angle adjustment mechanism 2, and the stabilizer 3 is provided on the other opposite side, one side of the mounting platform 4 is fixedly connected to one side of the stabilizer 3, and the mounting platform 4 and the angle adjustment mechanism 2 are respectively provided on two opposite sides of the stabilizer 3.

[0034] The working principle of the above technical solution: the visual acquisition device installs the entire device on the visual inspection instrument through the mounting platform 4, and the mounting platform 4 is sequentially connected with a stabilizer 3, an angle adjustment mechanism 2, and a camera assembly 1. The portion where the camera assembly 1 is connected to the angle adjustment mechanism 2 can also be provided with a rotating fixing device, so that the camera assembly 1 rotates along the axis of the angle adjustment mechanism 2, which is used to adjust the direction of the lens of the camera assembly 1. At the same time, the angle adjustment mechanism 2 can be used in conjunction with the angle to fine-tune the angle so that the lens of the camera assembly 1 is aligned with the weld to be inspected. The stabilizer 3 is used to ensure that the lens of the camera assembly 1 is always in a stable state and is not affected by vibration, so that the shooting is clearer and higher quality images are obtained.

[0035] The beneficial effects of the above technical solution: through the design of the above structure, when in use, when the weldment is sent into the visible range of the visual acquisition device or due to other reasons, the visual inspection instrument will inevitably produce slight vibrations, resulting in the lens position shift, or unable to capture a clear image due to vibration. The rotating fixing device and the angle adjustment mechanism 2 can manually adjust the position of the camera component 1, and the stabilizer 3 can ensure that the lens of the camera component 1 will not vibrate accordingly, thereby improving the quality of the collected image and thereby improving the detection efficiency.

[0036] In one embodiment, the camera assembly 1 includes a camera 11, a light source assembly 12, and a UV mirror 13. The UV mirror 13 is connected to the lens of the camera 11. The light source assembly 12 is sleeved on the outer side of the UV mirror 13. The light source assembly 12 is externally connected to a light source line 14.

[0037] The working principle of the above technical solution is as follows: a UV mirror 13 (i.e. UltraViolet, ultraviolet filter) is installed in front of the lens of the camera 11. The UV mirror 13 is a filter used by the camera 11 and matches the camera 11. A light source assembly 12 is sleeved on the outer side of the UV mirror 13. The light source assembly 12 is energized by an external light source line 14 to provide power to the light source assembly 12. An LED lamp electrically connected to the light source line 14 is provided in the light source assembly 12. After power is supplied, the LED lamp lights up, so that the light source assembly 12 illuminates the weld to be inspected and provides supplementary light for the camera 11.

[0038] The beneficial effects of the above technical solution: through the design of the above structure, the UV mirror 13 is installed in front of the lens to protect the lens and improve the picture quality. The light source assembly 12 provides light source for the camera 11 to ensure that the camera 11 can clearly shoot the weld to be inspected even in a dark environment, thereby ensuring the quality of the collected image and improving the detection efficiency.

[0039] In one embodiment, the angle adjustment mechanism 2 includes a support plate 21, an adjustment rod 22, and a locking piece 23. One side of the support plate 21 is connected to the camera assembly 1, and the other opposite side is connected to one end of the adjustment rod 22. The other end of the adjustment rod 22 is connected to the locking piece 23, and the end of the locking piece 23 away from the adjustment rod 22 is connected to the stabilizer 3.

[0040] The working principle of the above technical solution is: one side of the support plate 21 is connected to the camera 11 of the camera assembly 1, and the rotating fixing device can be provided between the two. The rotating fixing device has a similar structure to the angle adjustment mechanism 2, so that the camera assembly 1 rotates along the axis of the adjustment rod 22, and the other side of the support plate 21 opposite to the camera 11 is fixedly connected to one end of the adjustment rod 22, and the other end of the adjustment rod 22 is rotatably connected to the locking piece 23, so that the adjustment rod 22 drives the support plate 21 to rotate with the other end of the adjustment rod 22 as the rotation center, and the end of the locking piece 23 away from the adjustment rod 22 is connected to the stabilizer 3.

[0041] The beneficial effects of the above technical solution: through the design of the above structure, when the locking piece 23 is in a loosened state, the end of the adjusting rod 22 connected to the locking piece 23 can rotate relative to the locking piece 23 to adjust the angle. After the angle is adjusted, the locking piece 23 is tightened, and the locking piece 23 clamps and fixes the adjusting rod 22 so that the two no longer rotate relative to each other, and the adjusting rod 22 is fixed in the adjusted position. The structure is simple and the adjustment is convenient.

[0042] In one embodiment, one end of the adjusting rod 22 connected to the locking member 23 is a sphere 221, and limiting rods 222 are symmetrically provided on opposite sides of the sphere 221, and the limiting rods 222 are vertically arranged with the adjusting rod 22; the locking member 23 includes two locking plates 231 and a first locking screw 232, and the two locking plates 231 are symmetrically arranged, and an arc surface 2311 corresponding to the sphere 221 of the adjusting rod 22 is provided on the inner side of one end of the locking plate 231, and a circular hole 2312 corresponding to the limiting rod 222 is provided at the center of the arc surface 2311, and a first threaded hole 2313 is provided at the center position of the locking plate 231, and the axis of the first threaded hole 2313 is parallel to the axis of the circular hole 2312, and the thread directions of the first threaded holes 2313 on the two locking plates 231 are opposite; one end of the first locking screw 232 passes through the two first threaded holes 2313 and is connected with the two locking plates 231.

[0043] The working principle of the above technical solution is as follows: the arcuate surfaces 2311 on the two locking plates 231 surround one end of the sphere 221 connecting the adjusting rod 22 and the locking member 23; the two limiting rods 222 arranged on the sphere 221 are respectively inserted into the circular holes 2312 of the two locking plates 231, so that the adjusting rod 22 rotates with the axis of the limiting rod 222 as the rotation axis; the two locking plates 231 are connected to the first locking screw 232 through two first threaded holes 2313 with opposite thread directions; the first locking screw 23 When rotating in the forward direction, the two locking plates 231 approach each other under the action of their own elasticity, so that the arc surface 2311 squeezes the spherical shape 221, thereby locking and fixing the adjusting rod 22. When the angle needs to be adjusted, the first locking screw 232 rotates in the reverse direction, and the two locking plates 231 move away from each other and return to the initial state. The adjusting rod 22 can rotate along the axis of the limiting rod 222 to adjust the angle. When the two locking plates 231 are in the initial state, there is a certain distance between them, leaving a certain space for the locking state.

[0044] The beneficial effects of the above technical solution: through the design of the above structure, the two locking plates 231 can be adjusted to clamp the adjusting rod 22 only by adjusting the first locking screw 232 with external force. The structure is simple, the adjustment is convenient, and the locking and fixing are very reliable. The two locking plates 231 can be made of materials with good elasticity and toughness, and the two locking plates 231 are provided with threads in opposite directions, which makes the locking more secure and prevents the adjusting rod 22 from slipping.

[0045] In one embodiment, the stabilizer 3 includes two orthogonally arranged stabilizing units 31, the stabilizing units 31 include a box body 311 and a stabilizing block 312, the boxes 311 of the two stabilizing units 31 are fixedly connected, and the stabilizing block 312 is slidably connected in the box body 311; the front side surface of the box body 311 is provided with a rectangular limiting hole 3111 along its length direction, and the two opposite inner side surfaces of the box body 311 are provided with a first groove 3112 along its length direction, and the two opposite side surfaces of the stabilizing block 312 are provided with a protrusion 3121 corresponding to the first groove 3112, and the side surface of the stabilizing block 312 close to the limiting hole 3111 is connected with a connecting plate 3122, and the connecting plate 3122 extends out of the limiting hole 3111 and is arranged outside the box body 311, the connecting plate 3122 on one of the stabilizing blocks 312 is connected to the end of the angle adjustment mechanism 2 away from the camera assembly 1, and the connecting plate 3122 on the other stabilizing block 312 is connected to the mounting table 4;

[0046] Two first magnets 3113 are provided on the rear side of the inner side of the box body 311 along the length direction thereof, and the two first magnets 3113 are symmetrically arranged. A second magnet 3123 is provided on the side of the stabilizing block 312 away from the limiting hole 3111, and the first magnet 3113 and the second magnet 3123 have the same magnetic properties;

[0047] The stabilizing block 312 is disposed between the two first magnets 3113 , and the distance between the two first magnets 3113 is equal to the width of the second magnet 3123 in the length direction of the box 311 ;

[0048] The working principle of the above technical solution is as follows: the protrusion 3121 is slidably connected in the first groove 3112, so that the stabilizing block 312 slides in the box body 311 along the length direction of the box body 311, and the limiting hole 3111 can connect the connecting plate 3122 arranged outside the box body 311 with the stabilizing block 312, so that the connecting plate 3122 and the stabilizing block 312 move synchronously. When the mounting platform 4 vibrates, the vibration is decomposed into two orthogonal vibrations by the stabilizer 3, and the vibration in each direction causes the stabilizing block 312 to move synchronously. There is a small reciprocating motion in the box 311, and the amplitude of the vibration transmitted to the camera assembly 1 along the angle adjustment mechanism 2 is greatly reduced. Under the action of the same magnetic repulsion between the first magnet 3113 and the second magnet 3123, the stabilizing block 312 is always between the two first magnets 3113, and the stabilizing block 312 will not touch the two ends of the box 311, so the sliding speed of the stabilizing block 312 will not change suddenly. Therefore, the lens of the camera 11 will not produce a large shake, thereby increasing the stability of the lens of the camera 11.

[0049] The beneficial effects of the above technical solution: through the design of the above structure, under the repulsive magnetic force, the closer the distance between the repulsive magnetic poles of the stabilizing block 312 and the box body 311 is, the stronger the force is. Therefore, the more violent the vibration of the mounting table 4 is, the stronger the force between the stabilizing block 312 and the box body 311 is, and the better the stabilizing effect is. The spacing between the two first magnets 3113 is equal to the width of the second magnet 3123 in the length direction of the box body 311, which ensures the strength of the magnetic pole effect. When vibration occurs, the vibration transmitted to the camera assembly 1 is minimized, thereby improving the stability of the camera 11 when taking images, ensuring the accuracy of the detection results of detecting welded parts, and improving the detection efficiency.

[0050] In one embodiment, the mounting platform 4 includes a first mounting plate 41, a second mounting plate 42, and a second locking screw 43. One end of the first mounting plate 41 is provided with a clamping plate 44 perpendicular to the first mounting plate 41, and the other end is provided with a second groove 411 perpendicular to the clamping plate 44. One end of the second mounting plate 42 is provided with the clamping plate 44 perpendicular to the first mounting plate 41, and the other end corresponds to the second groove 411. The other end of the second mounting plate 42 is provided with a second threaded hole 421 whose axis is perpendicular to the clamping plate 44. The bottom surface of the second groove 411 is provided with a third threaded hole 412 corresponding to the second threaded hole 421, and one end of the second locking screw 43 passes through the second threaded hole 421 and the third threaded hole 412.

[0051] The working principle of the above technical solution: the mounting table 4 is used to install the visual acquisition device on the visual inspection instrument. The installation width of the mounting table 4 is adjusted by the first mounting plate 41 and the second mounting plate 42. When in use, first loosen the second locking screw 43 to make the end of the second mounting plate 42 corresponding to the second groove 411 away from the bottom surface of the second groove 411, and then use the clamping plate 44 to clamp it on the mounting frame on the visual inspection instrument, and then tighten the second locking screw 43. At this time, the second mounting plate 42 approaches the first mounting plate 41, and then the two clamping plates 44 clamp the mounting frame. The second groove 411 can limit the lateral displacement of the second mounting plate 42, and the sides of the two clamping plates 44 in contact with the mounting frame are provided with an anti-slip layer.

[0052] The beneficial effects of the above technical solution: through the design of the above structure, the mounting platform 4 can be suitable for mounting frames of different widths, and the mounting platform 4 and the mounting frame are easy to disassemble and assemble. The second locking screw 43 can be loosened or tightened only by external force, and then the distance between the two clamping plates 44 can be adjusted to achieve disassembly and assembly.

[0053] In one embodiment, the light source assembly 12 is electrically connected to one end of the light source line 14 , and the other end of the light source line 14 is provided with a USB interface.

[0054] The working principle and beneficial effects of the above technical solution: the other end of the light source line 14 is a USB interface, which is connected to the power supply via the USB interface, and the connection is stable. The light source line 14 provides power to the light source assembly 12, ensuring that the light source assembly 12 provides continuous light source for the camera 11, thereby ensuring the quality of the captured image.
