Description

Technical Field

[0001] The present invention relates to the technical field of optical detection, and more specifically, to an optical detection device with a supplementary light structure. Background Art

[0002] Optical detection is a method of detection and measurement using an optical system. By irradiating and reflecting a sample through optical elements and converting the optical signal into an electrical signal or a mechanical signal, relevant information of the sample can be obtained. According to different detection targets, optical detection can be divided into three categories: appearance detection, dimension detection, and topography detection.

[0003] When measuring the dimensions of an object, such as length, thickness, or the measurement of an irregular surface or contour, there is a problem of scattered light interference. That is, when light scatters on the surface of the object, interference will be formed. To reduce the measurement error caused by scattered light interference, generally, repeated measurements are carried out, and each time the measurement is taken, the angle and position of the optical sensor relative to the object to be measured are changed, and then an image processing algorithm is used to correct and remove the scattered light to improve the accuracy of the measurement result.

[0004] When the object to be measured is an object with a complex shape or unclear edges, supplementary lighting can enhance the contrast between the object edges and the background, making the edges clearer and distinguishable. This is very important for accurately measuring the dimensions of the object, such as length. For example, CN110595386A involves an annular auxiliary supplementary lighting device. Although this device can achieve omnidirectional supplementary lighting for objects with irregular surfaces by setting a driving rotation unit, a rotating part, and a supplementary light, this device can only make the supplementary light rotate around the object to be measured in a horizontal plane, and cannot adjust the angles and positions of the optical sensor (camera) and the supplementary light relative to the object to be measured, and cannot reduce the measurement error caused by scattered light interference, resulting in a low optical detection accuracy for the object. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to solve the problem in the prior art that the supplementary light can only rotate around the object to be measured in a horizontal plane, and cannot adjust the angles and positions of the optical sensor and the supplementary light relative to the object to be measured, and cannot reduce the measurement error caused by scattered light interference, resulting in a low optical detection accuracy for the object.

[0006] The purpose of the present invention is to provide an optical detection device with a supplementary light structure, which can synchronously adjust the angles of the optical sensor and the supplementary light relative to the object when driving the object to rotate, so as to ensure the optical detection accuracy of the object.

[0007] To achieve the above object, the present invention provides an optical detection device with a supplementary lighting structure, which includes a placement member and a detection member arranged on the placement member. The placement member includes a placement body and a driving body arranged inside the placement body. The placement body is used for placing an object to be measured, and the driving body is used to drive the placement body to rotate the object to be measured;

[0008] The detection member includes a movable ring body and a plurality of supplementary lighting scanning bodies arranged on the movable ring body. One end of the movable ring body is connected to the placement body in a vertical sliding manner, and the movable ring body is in transmission connection with the driving body. The movable ring body is used to adjust the angle of the supplementary lighting scanning body facing the object to be measured. When the driving body drives the placement body to rotate and then drives the object to be measured to rotate, the driving body synchronously drives the movable ring body to lift along the placement body, and at the same time, the driving body adjusts the angle of the supplementary lighting scanning body facing the object to be measured through the movable ring body.

[0009] As a further improvement of this technical solution, the placement body includes a central plate. One end of the bottom of the central plate is provided with a placement table, and a rotating disk is rotatably connected above the placement table. The rotating disk is used to place the object to be measured. A plurality of fixing plates are arranged on the surface of the rotating disk. One end of the top of the central plate is provided with a ceiling disk, and a lamp for lighting is arranged at the bottom of the ceiling disk.

[0010] As a further improvement of this technical solution, an inner cavity is opened in the central plate. The driving body includes a motor and a reciprocating lead screw located inside the inner cavity. The bottom end of the motor is connected to the reciprocating lead screw through a coupling, and the bottom end of the reciprocating lead screw is in transmission connection with the rotating disk through a belt drive.

[0011] As a further improvement of this technical solution, the movable ring body includes a winding ring and a lifting block arranged at one end of the winding ring. The lifting block is in vertical sliding connection with the inner wall of the inner cavity, and the reciprocating lead screw is in threaded connection with the lifting block. The driving body further includes a limiting plate arranged on the outer side inside the inner cavity, and the limiting plate is in plug-in fit with the lifting block.

[0012] As a further improvement of this technical solution, a movable plate and an angle adjustment structure slidably connected to one end of the movable plate are further arranged inside the movable ring body. One end of the angle adjustment structure away from the movable plate is slidably connected to the limiting plate. The winding ring is a ring-shaped structure with a "C" cross-section. The movable plate moves up and down in the groove of the winding ring, and drives the supplementary lighting scanning body to rotate through the up and down movement of the movable plate.

[0013] As a further improvement of this technical solution, a first connecting plate is arranged on the inner wall surface of the winding ring. The number of the first connecting plates is the same as the number of the supplementary lighting scanning bodies. A second connecting plate is rotatably connected inside the first connecting plate. One end of the second connecting plate is installed with a supplementary lighting scanning body, and the other end of the second connecting plate passes through the inner wall surface of the winding ring and is located in the groove of the winding ring. A connecting shaft is correspondingly arranged on the movable plate, and the connecting shaft is slidably connected to the second connecting plate.

[0014] As a further improvement of the technical solution, the angle adjustment structure includes a third connecting plate located inside the lifting block. The third connecting plate is rotatably connected to the inner wall of the lifting block through a set plate shaft, and both ends of the third connecting plate are slidably connected to the movable plate and the limiting plate respectively.

[0015] As a further improvement of the technical solution, a connecting groove is provided at one end of the movable plate close to the third connecting plate. One end of the third connecting plate is slidably connected to the connecting groove. A limiting groove is provided on the surface of the limiting plate, and the limiting groove is an arc-shaped groove. A roller is provided at the other end of the third connecting plate, and the roller is located in the limiting groove. The other end of the third connecting plate is slidably connected to the limiting groove through the provided roller.

[0016] As a further improvement of the technical solution, the light supplement scanning body includes an optical sensor installed at one end of the second connecting plate away from the movable plate. A plurality of supplementary light lamps are fixedly installed on the surface of the optical sensor. A reflection arc plate for focusing the reflection optical fiber on the object is also provided at one end of the second connecting plate surface close to the optical sensor.

[0017] In the present invention, after the object to be measured is placed on the placement body, the driving body drives the placement body to rotate, so that the object to be measured rotates to facilitate the light supplement scanning body to perform a comprehensive dimensional measurement on the object. Among them, when the driving body drives the placement body to rotate and then drives the object to be measured to rotate, the driving body synchronously drives the movable ring body to move up and down along the placement body, and at the same time, the driving body adjusts the angle of the light supplement scanning body facing the object to be measured through the movable ring body.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the optical detection device with a light supplement structure, when the motor drives the reciprocating lead screw to rotate, and then drives the rotating disk to rotate to make the object rotate, the reciprocating lead screw synchronously drives the sleeve ring to move up and down, which can synchronously change the height of the light supplement scanning body when the object rotates, so as to facilitate the light supplement scanning body to repeat the measurement of the object at different heights. And when the movable ring body moves up and down along the limiting plate, the angle adjustment structure will drive the movable plate to move up and down, and then drive the light supplement scanning body to rotate through the up and down movement of the movable plate, so as to adjust the angle of the light supplement scanning body relative to the object to be measured, which can reduce the measurement error caused by the interference of scattered light and ensure the optical detection accuracy of the object.

[0020] 2. In the optical detection device with a light supplement structure, by providing supplementary light lamps on the optical sensor and a reflection arc plate on the second connecting plate, when the second connecting plate drives the optical sensor to rotate to adjust the angle of the optical sensor relative to the object, the supplementary light lamps and the reflection arc plate can rotate synchronously, and the supplementary light lamps are used to illuminate the object to enhance the contrast between the object edge and the background, and then the reflection arc plate focuses the reflected light on the object, so that the optical sensor can obtain a bright and clear image, which is beneficial to the optical detection of the object.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0036] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more, unless otherwise specifically defined.

[0037] In order to be able to adjust the angles and positions of the optical sensor and the fill light with respect to the object to be measured, so as to reduce the measurement error caused by scattered light interference, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the purpose of this embodiment is to provide an optical detection device with a fill light structure, including a placement member 1 and a detection member 2 provided on the placement member 1;

[0038] The placement member 1 includes a placement body 11 and a driving body 12 provided in the placement body 11. The placement body 11 is used for placing the object to be measured, and the driving body 12 is used for driving the placement body 11 to rotate the object to be measured;

[0039] The detection member 2 includes a movable ring body 21 and a plurality of supplementary light scanning bodies 22 arranged on the movable ring body 21. One end of the movable ring body 21 is slidably connected to the placement body 11 up and down, and the movable ring body 21 is in transmission connection with the driving body 12. The movable ring body 21 is used to adjust the angle of the supplementary light scanning body 22 facing the object to be measured. After the object to be measured is placed on the placement body 11, the driving body 12 drives the placement body 11 to rotate, so that the object to be measured rotates to facilitate the supplementary light scanning body 22 to perform a comprehensive dimensional measurement of the object. Among them, when the driving body 12 drives the placement body 11 to rotate and then drives the object to be measured to rotate, the driving body 12 synchronously drives the movable ring body 21 to lift along the placement body 11, and the driving body 12 simultaneously adjusts the angle of the supplementary light scanning body 22 facing the object to be measured through the movable ring body 21.

[0040] The above structure is disclosed as follows:

[0041] First, after the object is placed on the rotating disk 1121, in order to obtain the complete surface information of the object to facilitate the dimensional measurement of the object, as Figure 3 shown, the placement body 11 includes a central plate 111. One end of the bottom of the central plate 111 is provided with a placement table 112. A rotating disk 1121 is rotatably connected above the placement table 112. The rotating disk 1121 is used to place the object to be measured. A plurality of fixing plates 1122 are provided on the surface of the rotating disk 1121. By passing a rope through the holes of the fixing plates 1122 to bind the object or using a bracket to fix the object on the fixing plates 1122, the shaking of the object during rotation can be avoided, and measurement errors can be avoided. One end of the top of the central plate 111 is provided with a ceiling disk 113. A lamp for lighting is provided at the bottom of the ceiling disk 113. An inner cavity 1111 is opened in the central plate 111. The driving body 12 includes a motor and a reciprocating lead screw 121 located in the inner cavity 1111. The bottom end of the motor is connected to the reciprocating lead screw 121 through a coupling. The bottom end of the reciprocating lead screw 121 is in transmission connection with the rotating shaft at the bottom end of the rotating disk 1121 through a belt drive. After the object to be measured is placed on the rotating disk 1121 and then fixed, the motor drives the reciprocating lead screw 121 to rotate in the inner cavity 1111. The bottom end of the reciprocating lead screw 121 then drives the rotating disk 1121 to rotate through a belt drive connection, so that the object located on the rotating disk 1121 is driven to rotate, and the supplementary light scanning body 22 scans the rotating object to facilitate obtaining the complete surface information of the object.

[0042] Since the object has a certain height, when the supplementary light scanning body 22 measures the size of the object, in order to ensure the measurement accuracy of the object size, the supplementary light scanning body 22 needs to repeatedly measure the object at different heights during measurement, as Figure 5As shown, the movable ring body 21 includes a winding sleeve ring 211 and a lifting block 212 disposed at one end of the winding sleeve ring 211. The lifting block 212 is located within the inner cavity 1111 and is slidably connected to the inner wall of the inner cavity 1111 in the up and down direction. The bottom end of the reciprocating lead screw 121 passes through the lifting block 212 and is threadedly connected to the lifting block 212. The driving body 12 further includes a limiting plate 122 disposed on the outer side within the inner cavity 1111. The bottom end of the limiting plate 122 passes through the lifting block 212 and is in plug-in fit with the lifting block 212. When the motor drives the reciprocating lead screw 121 to rotate, thereby driving the rotating disk 1121 to rotate and enabling the object to rotate, the reciprocating lead screw 121 synchronously drives the winding sleeve ring 211 to move up and down along the limiting plate 122 through the lifting block 212. Thus, the height of the light supplement scanning body 22 can be synchronously changed when the object rotates, facilitating the light supplement scanning body 22 to repeatedly measure the object at different heights.

[0043] Furthermore, in order to be able to adjust the angle of the light supplement scanning body 22 relative to the object to be measured and reduce the measurement error caused by scattered light interference, as Figure 6 、 Figure 7 shown, a movable plate 213 and an angle adjustment structure slidably connected to one end of the movable plate 213 are further provided within the movable ring body 21. The angle adjustment structure is located within the lifting block 212 and is rotatably connected to the lifting block 212. The end of the angle adjustment structure away from the movable plate 213 is slidably connected to the limiting plate 122. The winding sleeve ring 211 is a ring-shaped structure with a "C"-shaped cross-section. The movable plate 213 moves up and down within the groove of the winding sleeve ring 211. By the up and down movement of the movable plate 213, the light supplement scanning body 22 is driven to rotate. When the movable ring body 21 moves up and down along the limiting plate 122, the angle adjustment structure slidably connected to the limiting plate 122 will drive the movable plate 213 to move up and down within the groove of the winding sleeve ring 211, and then drive the light supplement scanning body 22 to rotate through the up and down movement of the movable plate 213 to adjust the angle of the light supplement scanning body 22 relative to the object to be measured.

[0044] The movable plate 213 and the angle adjustment structure are specifically disclosed as follows:

[0045] In order to drive the up-and-down movement of the movable plate 213, the angle adjustment structure includes a third connecting plate 2121 located inside the lifting block 212. On both sides of the middle of the third connecting plate 2121, there are plate shafts inserted into the inner wall of the lifting block 212. The third connecting plate 2121 is rotationally connected to the inner wall of the lifting block 212 through the provided plate shafts. Both ends of the third connecting plate 2121 are slidably connected to the movable plate 213 and the limiting plate 122 respectively. Specifically, a connecting groove 2132 is formed at one end of the movable plate 213 close to the third connecting plate 2121, and one end of the third connecting plate 2121 is slidably connected to the connecting groove 2132. A limiting groove 1221 is formed on the surface of the limiting plate 122, and the limiting groove 1221 is an arc-shaped groove. A roller 2122 is provided at the other end of the third connecting plate 2121, and the roller 2122 is located in the limiting groove 1221. The other end of the third connecting plate 2121 is slidably connected to the limiting groove 1221 through the provided roller 2122. When the movable ring body 21 moves up and down along the limiting plate 122, the roller 2122 slides in the limiting groove 1221. Since the limiting groove 1221 is of an arc-shaped groove structure, during the sliding, the roller 2122 will drive the third connecting plate 2121 to rotate inside the lifting block 212, driving the movable plate 213 slidably connected to one end of the third connecting plate 2121 to move up and down along the groove of the sleeve ring 211.

[0046] Then, when the movable plate 213 moves up and down, in order to drive the rotation of the light supplement scanning body 22, a first connecting plate 2111 is provided on the inner wall surface of the sleeve ring 211. The number of the first connecting plates 2111 is the same as the number of the light supplement scanning bodies 22. A second connecting plate 2112 is rotationally connected inside the first connecting plate 2111. A light supplement scanning body 22 is installed at one end of the second connecting plate 2112. The other end of the second connecting plate 2112 passes through the inner wall surface of the sleeve ring 211 and is located in the groove of the sleeve ring 211. A connecting shaft 2131 is correspondingly provided on the movable plate 213. The connecting shaft 2131 passes through the other end of the second connecting plate 2112 and is slidably connected to the second connecting plate 2112. When the angle adjustment structure drives the movable plate 213 to move up and down in the groove of the sleeve ring 211, the connecting shaft 2131 of the movable plate 213 will slide along the other end of the second connecting plate 2112, thereby driving the second connecting plate 2112 to rotate inside the first connecting plate 2111, changing the relative angle between the light supplement scanning body 22 installed at one end of the second connecting plate 2112 and the object to be measured, so as to reduce the measurement error caused by the interference of scattered light.

[0047] When detecting an object, it is necessary to supplement light to enhance the contrast between the object edge and the background, making the edge clearer and more distinguishable, such as Figure 8As shown in the figure, the supplementary light scanning body 22 includes an optical sensor 221 installed at one end of the second connecting plate 2112 away from the movable plate 213. A plurality of supplementary light lamps 222 are fixedly installed on the surface of the optical sensor 221. A reflecting arc plate 223 for gathering the reflecting optical fibers on the object is also provided at one end of the second connecting plate 2112 near the optical sensor 221. By arranging the supplementary light lamps 222 on the optical sensor 221 and the reflecting arc plate 223 on the second connecting plate 2112, when the second connecting plate 2112 drives the optical sensor 221 to rotate to adjust the angle of the optical sensor 221 relative to the object, the supplementary light lamps 222 and the reflecting arc plate 223 can rotate synchronously. The supplementary light lamps 222 illuminate the object to enhance the contrast between the object edge and the background, and then the reflecting arc plate 223 focuses the reflected light on the object, so that the optical sensor 221 can obtain a bright and clear image, which is beneficial to the optical detection of the object.

[0048] In summary, when the motor drives the reciprocating lead screw 121 to rotate, and then drives the rotating disk 1121 to rotate through the reciprocating lead screw 121 to make the object rotate, the reciprocating lead screw 121 synchronously drives the sleeve ring 211 to move up and down reciprocally to change the height of the supplementary light scanning body 22. When the sleeve ring 211 moves up and down, it will also drive the supplementary light scanning body 22 to rotate, so that the angle of the supplementary light scanning body 22 relative to the object changes. The angle adjustment of the supplementary light scanning body 22 is as Figure 9 shown.

[0049] Specifically, the angle adjustment principle of the supplementary light scanning body 22 is as Figure 10 shown. When the reciprocating lead screw 121 drives the rotating disk 1121 to rotate in the direction shown by the arrow a, the lifting block 212 threadedly connected to the reciprocating lead screw 121 synchronously drives the sleeve ring 211 to move up and down along the limiting plate 122, as shown by the arrow b. When the sleeve ring 211 moves up and down along the limiting plate 122, the lifting block 212 synchronously drives the third connecting plate 2121 to move. Since the roller 2122 at one end of the third connecting plate 2121 slides along the limiting groove 1221 opened on the limiting plate 122, and the limiting groove 1221 is an arc-shaped groove, when the sleeve ring 211 moves up and down along the limiting plate 122, the third connecting plate 2121 will rotate within the lifting block 212, as shown by the arrow c, thereby driving the movable plate 213 to move up and down in the groove of the movable plate 213, and then driving the second connecting plate 2112 to rotate within the first connecting plate 2111 through the up and down movement of the movable plate 213, changing the angle of the optical sensor 221 installed at one end of the second connecting plate 2112 facing the object to be measured.

[0050] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
