Description

Technical Field

[0001] The utility model relates to the technical field of visual detection, in particular to an adjustable thread visual detection component. Background Art

[0002] A visual inspection system uses industrial cameras to replace the human eye to perform functions such as identification, measurement, and positioning. Typically, a visual inspection system consists of a camera, lens, and light source. It can replace manual inspection for barcode characters, cracks, packaging, surface coating integrity, and dents. Using a visual inspection system can effectively improve the speed and accuracy of inspections on production lines, significantly increasing production and quality, reducing labor costs, and preventing misjudgments caused by eye fatigue.

[0003] At present, most visual inspection equipment is automated. The workpiece to be inspected is driven by a disc or belt-type drive structure through the upper or lower part of the camera in sequence. The camera takes pictures of the parts, and the pictures are processed and classified by measurement software to determine whether the parts meet the requirements. Specifically in the field of thread inspection, the thread is photographed by a camera to detect the concentricity of the thread and whether the thread is damaged. Compared with traditional manual inspection, visual inspection is more efficient, but the sizes of different parts are different during the visual inspection process. The position of the camera needs to be adjusted to ensure focus, because the out-of-focus will seriously affect the photo effect. Therefore, a high-precision micro-adjustment mechanism becomes very important. Utility Model Content

The described embodiments are only part of the embodiments of the utility model, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making any creative efforts are within the scope of protection of the utility model.

[0023] In the related existing technologies, the sizes of parts from different batches vary during the visual inspection process, and the position of the camera needs to be adjusted to ensure focus. Because out-of-focus will seriously affect the photo effect, a high-precision micro-adjustment mechanism becomes very important.

[0024] In order to solve the problems existing in the related prior art, the present invention proposes an adjustable thread visual detection component. The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0025] See also Figures 1 to 4 An adjustable thread visual inspection component includes a detection camera 1, a light source 2, and a fixing plate 3 for fixing the detection camera 1 and the light source 2. Specifically, there are two light sources 2, which are respectively located at the upper and lower parts of the workpiece, and at the same time provide fill light for the parts to improve the brightness and ensure the shooting effect. The fixing plate 3 is extended and connected to the adjustment base, and the horizontal position and height of the detection camera 1 and the light source 2 are adjusted through the adjustment base;

[0026] The adjustment seat includes a base 4, a first slide 5, a second slide 6 and a third slide 7 from bottom to top. The base 4 and the first slide 5 slide along the first direction, the first slide 5 and the second slide 6 slide along the second direction, and the second slide 6 and the third slide 7 slide along the third direction. The specific sliding structure is a guide rail slide structure or other structure that can achieve relative sliding, and the first direction, the second direction and the third direction are perpendicular to each other. A spiral adjustment mechanism is also provided on the side of the adjustment seat, which is adjusted in three directions through the adjustment seat, thereby driving the camera to adjust horizontally and up and down to ensure that the camera is focused on the parts and improve the shooting accuracy.

[0027] Specifically, in this embodiment, the first direction and the second direction are horizontally perpendicular, and the third direction is a vertical direction. In some other embodiments, the first direction may be a vertical direction, and the second direction and the third direction may be horizontally perpendicular to each other.

[0028] Specifically, the spiral adjustment mechanism includes a first adjustment mechanism 8 and a second adjustment mechanism 9. The first adjustment mechanism 8 is composed of two mechanisms that respectively control sliding in a first direction and sliding in a second direction, and the second adjustment mechanism 9 controls sliding in a third direction.

[0029] The first adjustment mechanism 8 includes a screw 8a, a first knob 8b, and two connecting blocks 8c. The two connecting blocks 8c are connected to the screw 8a and the first knob 8b, respectively. The first knob 8b has an internal thread that cooperates with the screw 8a. By rotating the first knob, the two connecting blocks 8c are driven to move relative to each other. The two connecting blocks 8c of one first adjustment mechanism 8 are respectively fixed to the base 4 and the first slide 5. The two connecting blocks 8c of the other first adjustment mechanism 8 are respectively fixed to the first slide 5 and the second slide 6. By rotating the first knob, the two connecting blocks 8c are driven to move relative to each other, thereby driving the base connected to the connecting blocks 8c and the first slide 5 to slide relative to each other. The other first adjustment mechanism 8 also drives the first slide 5 and the second slide 6 to slide relative to each other.

[0030] The second adjusting mechanism 9 includes a second knob 9a, a threaded block 9b and a rotating block 9c. The second knob 9a cooperates with the threaded block 9b, the threaded block 9b is fixed on the second slide 6, and the rotating block 9c is "L"-shaped. The head end of the second knob 9a contacts one end of the rotating block 9c, and the other end of the rotating block 9c cooperates with the third slide 7. By rotating the second knob 9a, the head end of the second knob 9a extends or retracts from the threaded block 9b, driving the rotating block 9c to rotate forward or reverse, thereby driving the third slide 7 to move upward or downward.

[0031] The adjustment seat also includes a fixing mechanism 10, which includes a fixing plate 10a and a third knob 10b. The fixing mechanism 10 is used to fix the base 4, the first slide 5, the second slide 6 and the third slide 7 to prevent them from sliding against each other after adjustment. A sliding groove is provided on the fixing plate 10a, and the third knob 10b passes through the sliding groove. The fixing is achieved by tightening the third knob 10b.

[0032] Specifically, a fixing mechanism is provided on the base 4 and the first slide 5, wherein a fixing plate 10a is fixed on the base, and a sliding groove is provided on the fixing plate 10a, the direction of the sliding groove is the same as the relative sliding direction of the base and the first slide 5, and the third knob 10b is connected to the first slide 5 through the sliding groove. When the base 4 and the first slide 5 need to be adjusted to slide relative to each other, the third knob 10b is loosened, and after the adjustment is completed, the third knob 10b is tightened to lock the base 4 and the first slide 5. Similarly, fixing mechanisms are also provided on the first slide 5 and the second slide 6, and fixing mechanisms are also provided on the second slide 6 and the third slide 7.

[0033] During the specific operation, when the camera position needs to be adjusted, the inspection camera 1 is adjusted in the horizontal and vertical directions by turning the two first knobs 8b and the second knob 9a to achieve focus on the camera and the part. When the adjustment in one direction is completed, the corresponding interconnected third knobs 10b are locked. When the rotation in three directions is completed, the three third knobs 10b are all locked and fixed. In this way, in the subsequent work process, the vibration of the whole machine will not affect the camera position, ensuring normal detection.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
