Description

Technical Field

[0001] The present invention relates to the technical field of image measurement equipment, and in particular to a positioning measurement equipment based on 3D vision. Background Art

[0002] An image measuring instrument is a non-contact three-dimensional measuring device that mainly measures by taking three-dimensional points. It is also called a 3D image measuring instrument. The image measuring instrument uses automatic optical focus scanning to measure. The camera captures the image and transmits the data to the computer. The software system synthesizes an intuitive image. The analyst analyzes the image data and then draws the final data conclusion. It not only realizes the concretization of the workpiece shape, length, width, and height, but also can accurately measure the surface flatness of the workpiece.

[0003] Generally, after a measuring instrument has been operating for a period of time, static electricity generated by the current will cause dust to adhere to the scanning lens, thereby affecting measurement accuracy. If a fan is installed on the outside of the measuring instrument, not only will the measurement cost increase, but the staff will also need to turn on the fan switch before each measurement, causing additional workload.

[0011] Furthermore, the cleaning assembly includes a rotating frame, which has two symmetrical rotating frames, the outer wall of the rotating frame being rotatably connected to the outer wall of the U-shaped frame, and the opposite side of the rotating frame being rotatably connected to a dust collection shell, the top of the dust collection shell is evenly provided with air holes, the inner wall of the dust collection shell is evenly provided with dust strips, the outer wall of the dust strips is fixedly connected to the inner wall of the dust collection shell, and the opposite side of the inner wall of the dust collection shell is rotatably connected to a rotating rod, and the outer wall of the rotating rod is evenly provided with soft cloth strips, the outer wall of the soft cloth strip is fixedly connected to the outer surface of the rotating rod, the soft cloth strip enters the interior of the dust collection shell and contacts the dust strip, and under the collision with the dust strip, the dust adsorbed on the soft cloth strip is knocked off, so that the dust is collected through the air holes, thereby reducing the generation of smoke and dust during cleaning, and the soft cloth strip has a large adsorption force on the dust, which prevents electrostatic dust from being difficult to be sucked away, and helps to better clean the loading platform.

[0013] Furthermore, the placing assembly includes a driving block, the top of the driving block is fixedly connected to the top of the collecting shell, the inner wall of the driving block is evenly provided with moving rods, the outer wall of the moving rod is slidably connected to the inner wall of the driving block, a limiting plate is provided at one end of the moving rod away from the driving block, the top of the limiting plate is fixedly connected to the bottom of the collecting shell, the inner wall of the limiting plate is socketed with the outer wall of the moving rod, the end of the moving rod away from the limiting plate is fixedly connected with a push rod, the side of the push rod away from the moving rod is symmetrically provided with a support rod, the side of the push rod close to the support rod is slidably connected with a connecting rod, the outer wall of the connecting rod is slidably connected to the outer wall of the support rod, and the object is pushed directly under the lens for measurement, avoiding the objects from being randomly placed and loaded, resulting in the need for manual adjustment, which increases the workload of workers.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. After the measuring instrument has been working for a period of time, dust will be adsorbed on the scanning lens due to static electricity generated by the current, thereby affecting the measurement accuracy. The present invention cleans the dust on the lens by setting a measuring mechanism. Since the alcohol is wiped, a certain amount of static electricity can be eliminated at the same time, reducing the subsequent adhesion of dust. The lens is then wiped dry by the drying component and then taken out to keep the lens surface dry and clean, avoiding alcohol from contaminating the lens again when exposed to the outside. The cleaning component cleans and adsorbs the dust on the surface of the stage to reduce the contact between dust and the lens.

[0016] 2. When measuring an object, it is usually placed manually on the stage and then the placement of the object is manually adjusted. The present invention provides a loading mechanism, which allows gravity to cause the object to slide downward along the conveyor roller. When the object passes through the extrusion assembly, the fixed bar causes the object to shake and buffers the speed of the object to prevent it from sliding directly from the conveyor roller and falling quickly onto the stage, causing damage to the stage. The extrusion assembly cleans debris and dust on the top of the object and prevents the object from tipping over. After the object is placed on the stage, the placement assembly pushes the object toward the vision measuring instrument so that the regularly shaped object is placed facing the vision measuring instrument, reducing the time and operation of manual angle adjustment and improving work efficiency.

[0017] 3. Since objects are manually carried and placed on the stage, it is easy to cause a lot of dust on the stage, which affects the measurement. The present invention sets a cleaning component, and a soft cloth strip adsorbs and cleans the dust on the stage. Then, driven by the rotating rod, the soft cloth strip enters the dust collection shell and contacts the dusting strip. Under the collision with the dusting strip, the dust adsorbed on the soft cloth strip is knocked off, and the dust is collected through the air holes, reducing the generation of smoke and dust during cleaning. The soft cloth strip has a strong adsorption force on dust, which prevents electrostatic dust from being easily sucked away, helps to better clean the stage, reduces the contact between dust and the lens, and thus extends the use time of the lens.

[0018] 4. Since dust is adsorbed on the lens after a long period of use, installing a fan on the outside of the measuring instrument not only increases the measurement cost, but also requires the staff to turn on the fan switch before each measurement, causing extra workload. The present invention provides a wiping component and a drying component, and uses alcohol to adsorb the dust on the lens, which can not only achieve cleaning, but also reduce the static electricity of the lens, so that the cleaning effect can last for a long time. After alcohol cleaning, the lens is immediately dried and wiped to avoid traces of residual alcohol on the lens, further enhancing the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0031] Example 1: Use Figure 1-Figure 4 A 3D vision-based positioning measurement device according to an embodiment of the present invention is described as follows.

[0032] like Figure 1-Figure 4 As shown, the 3D vision-based positioning and measurement device of the present invention comprises: a loading platform 1, the surface of the loading platform 1 is smooth and easily accumulates dust after long-term use, and a loading mechanism 3 is fixedly connected to the top of the loading platform 1;

[0033] The 3D vision-based positioning measurement device also includes:

[0034] The measuring mechanism 2 has a bottom portion slidably connected to the top portion of the stage 1 .

[0035] During work, the worker places the object to be measured on the loading mechanism 3. The object passes through the loading mechanism 3 to clean the debris attached to the surface, and is driven by the loading mechanism 3 to contact the top of the loading platform 1. The loading mechanism 3 pushes the object to the bottom of the cleaning mechanism, and the cleaning mechanism is used for measurement. After a period of use, the cleaning mechanism cleans the surface of the 3D measuring instrument and the loading platform 1.

[0036] The loading mechanism 3 includes a base 301, the bottom of the base 301 is fixedly connected to the side of the top of the sample stage 1 away from the measuring mechanism 2, the outer wall of the base 301 is rotatably connected to the collection shell 302, the bottom of the collection shell 302 is provided with a dust suction hole, and the collection shell 302 needs to be connected to an external vacuum cleaner when in use, the inner wall of the collection shell 302 is evenly provided with transmission rollers 303, both ends of the transmission roller 303 are rotatably connected to the inner wall of the collection shell 302, the outer wall of the collection shell 302 is fixedly connected to the extrusion component 305, the outer wall of the transmission roller 303 near the bottom of the extrusion component 305 is evenly provided with fixing bars 304, and the outer side of the transmission roller 303 arranged at the bottom of the extrusion component 305 is provided with a fixing bar 304, which is used to produce a certain degree of shaking of the object to be measured, so that the debris falls off quickly into the collection shell 302, the outer wall of the fixing bar 304 is fixedly connected to the outer wall of the transmission roller 303, and the bottom of the collection shell 302 is fixedly connected with a placement component 306.

[0037] During operation, the base 301 drives the bottom of the collection shell 302 to contact the top of the stage 1, and then places the object to be measured on the transmission roller 303. The object slides downward along the transmission roller 303 due to gravity. When the object passes through the squeezing component 305, the fixing bar 304 drives the object to shake and buffers the speed of the object to prevent it from sliding directly from the transmission roller 303, causing the object to fall quickly onto the stage 1 and damage the stage 1. The squeezing component 305 cleans the debris and dust on the top of the object and prevents the object from tipping over. After the object is placed on the stage 1, the placing component 306 pushes the object toward the vision measuring instrument 202, so that the regularly shaped object is placed facing the vision measuring instrument 202, reducing the time and operation of manual angle adjustment and improving work efficiency.

[0038] The measuring mechanism 2 includes a U-shaped frame 206. The bottom of the U-shaped frame 206 is slidably connected to the top of the loading platform 1. The outer wall of the U-shaped frame 206 near one end of the loading mechanism 3 is rotatably connected to the cleaning component 205. The cleaning component 205 can be rotated and lifted upward when not in use to avoid occupying the space of objects and affecting loading. The outer surface of the U-shaped frame 206 is slidably connected to the sliding bracket 201 on the side away from the cleaning component 205. The end of the sliding bracket 201 away from the U-shaped frame 206 is slidably connected to the visual measuring instrument 202. For objects of different heights, the visual measuring instrument 202 can automatically adjust the height. The bottom of the sliding bracket 201 is fixedly connected to the telescopic column 203. The bottom of the telescopic column 203 is rotatably connected to the drying component 207. The outer wall of the drying component 207 is fixedly connected to the wiping component 204.

[0039] During operation, the vision measuring instrument 202 automatically scans and measures the object. After a period of use, dust may adhere to the lens of the vision measuring instrument 202 due to static electricity. At this time, the telescopic column 203 drives the wiping component 204 to rotate 180 degrees, aligns the wiping component 204 with the lens position, and inserts the lens into the wiping component 204. The wiping component 204 contains alcohol, which cleans the dust on the lens and eliminates a certain amount of static electricity at the same time. By wiping the dust on the lens with alcohol, a certain amount of static electricity can be eliminated at the same time, reducing the subsequent adhesion of dust. The lens is then wiped dry by the drying component 207 and then removed to keep the lens surface dry and clean, preventing alcohol from contaminating the lens again when exposed to the outside. The cleaning component 205 cleans and absorbs the dust on the surface of the stage 1 to reduce the contact between dust and the lens.

[0040] Example 2: Use Figures 1-10 A 3D vision-based positioning measurement device according to an embodiment of the present invention is described as follows.

[0041] like Figures 1-10As shown, the positioning and measuring device based on 3D vision described in the present invention, on the basis of embodiment 1, the wiping component 204 includes a cover plate 2041, the inner wall of the cover plate 2041 is fixedly connected to the outer wall of the telescopic column 203, and initially, the cover plate 2041 covers the top of the rotating shell 2042. When cleaning, the cover plate 2041 does not move, and the rotating shell 2042 rotates 180 degrees to align with the lens. After cleaning is completed, it rotates back to its original position, and the cover plate 2041 covers it again to prevent the alcohol in the rotating shell 2042 from evaporating, so that the bottom of the telescopic column 203 is fixedly connected to the rotating shell 2042, and the top of the rotating shell 2042 is fixedly connected to the rotating shell 2042. In contact with the bottom of the cover 2041, the bottom of the inner wall of the rotating shell 2042 is fixedly connected with a spring 2043, the top of the spring 2043 is fixedly connected with a ring 2044, and the inner wall of the ring 2044 is evenly provided with rotating blocks 2045. The bottom of the rotating block 2045 is in an outward-extending state at the initial time. Alcohol cotton is set at the bottom of the rotating block 2045. The alcohol content is low, which is enough to absorb and wipe the dust on the lens. The top of the rotating block 2045 is rotatably connected to the inner wall of the ring 2044, and the inner wall of the ring 2044 is slidably connected to a limit ring 2046. The limit ring 2046 is located above the rotating block 2045.

[0042] The drying component 207 includes a mounting groove 2071, the outer wall of the mounting groove 2071 is fixedly connected to the outer wall of the rotating shell 2042, the inner wall of the mounting groove 2071 is rotatably connected to the wiping cloth 2072, the end of the wiping cloth 2072 away from the mounting groove 2071 is rotatably connected to the inner wall of the rotating shell 2042, the outer wall of the wiping cloth 2072 is socketed with the inner wall of the ring 2044, the bottom of the rotating shell 2042 is fixedly connected to the telescopic rod 2073, the top of the telescopic rod 2073 is fixedly connected to the protrusion 2074, and the bottom of the protrusion 2074 is fixedly connected to the expansion piece 2075.

[0043] When cleaning is needed, the motor provided at the bottom of the telescopic rod 2073 drives the rotating shell 2042 to rotate and align with the lens, and then driven by the telescopic rod 2073, the ring 2044 covers the lens. Before the lens enters the ring 2044, the lens contacts the alcohol cotton, so that dust is adsorbed on the alcohol cotton. At this time, the outer wall of the lens contacts the limit ring 2046. The inner diameter of the limit ring 2046 is larger than the lens but smaller than the lens, so that the alcohol cotton contacts the lens and will be stuck in the limit ring 2046.

[0044] As the lens gradually moves downward, the lens drives the limiting ring 2046 to move downward, and the limiting ring 2046 squeezes the rotating block 2045, so that the bottom of the rotating block 2045 gradually sticks to the ring 2044, thereby driving the alcohol cotton away from the lens, and the limiting ring 2046 remains stationary. At this time, the telescopic rod 2073 extends, and the protrusion 2074 contacts the wiping cloth 2072, and the wiping cloth 2072 is lifted up to contact the lens. The diameter of the protrusion 2074 is the same as the diameter of the lens. The wiping cloth 2072 is a non-chip and elastic cloth. When wiping the lens, it absorbs alcohol and keeps the lens dry. Then the lens is pulled out of the ring 2044, and the telescopic rod 2073 continues to move upward.

[0045] The expansion piece 2075 contacts the bottom of the rotating block 2045. During the upward movement of the expansion piece 2075, the rotating block 2045 is lifted, driving the limit ring 2046 and the rotating block 2045 back to their original positions. Then the telescopic rod 2073 is retracted, and the mounting groove 2071 drives the wiping cloth 2072 to reel up, so that the unused part is located on the top of the protrusion 2074, waiting for the next use.

[0046] Using alcohol to absorb dust on the lens can not only clean it, but also reduce static electricity on the lens, making the cleaning effect last longer. After alcohol cleaning, wipe the lens dry immediately to avoid traces of alcohol residue on the lens and further enhance the cleaning effect.

[0047] The cleaning component 205 includes a rotating frame 2051, and two rotating frames 2051 are symmetrically arranged. The outer wall of the rotating frame 2051 is rotatably connected to the outer wall of the U-shaped frame 206, and the opposite side of the rotating frame 2051 is rotatably connected to the dust collection shell 2052, and the top of the dust collection shell 2052 is evenly provided with air holes 2056. The top of the dust collection shell 2052 is externally connected to the vacuum cleaner, and the inner wall of the dust collection shell 2052 is evenly provided with dusting strips 2053. The outer wall of the dusting strip 2053 is fixedly connected to the inner wall of the dust collection shell 2052, and the opposite side of the inner wall of the dust collection shell 2052 is rotatably connected to the rotating rod 2054. The outer wall of the rotating rod 2054 is evenly provided with soft cloth strips 2055, and the outer wall of the soft cloth strip 2055 is fixedly connected to the outer surface of the rotating rod 2054.

[0048] After measuring multiple objects, dust will also accumulate on the surface of the stage 1. At this time, the base 301 lifts the collection shell 302, and the rotating frame 2051 drives the dust collection shell 2052 to rotate to the top of the stage 1, so that the soft cloth strip 2055 contacts the top of the stage 1. Driven by the U-shaped frame 206, the soft cloth strip 2055 can clean the entire surface of the stage 1. The soft cloth strip 2055 absorbs and cleans the dust on the stage 1. Then, driven by the rotating rod 2054, the soft cloth strip 2055 enters the dust collection shell 2052 and contacts the dusting strip 2053. Under the collision with the dusting strip 2053, the dust adsorbed on the soft cloth strip 2055 is knocked off, and the dust is collected through the air hole 2056, reducing the smoke generated during cleaning. The soft cloth strip 2055 has a large adsorption force on the dust, which prevents electrostatic dust from being difficult to be sucked away, helping to better clean the stage 1.

[0049] The extrusion assembly 305 includes a cover plate 3051, the inner wall of the cover plate 3051 is fixedly connected to the outer wall of the collection shell 302, the inner wall of the cover plate 3051 is slidably connected to the bent rod 3052, the outer surface of the bent rod 3052 is provided with a first sleeve 3053, the inner wall of the first sleeve 3053 is socketed with the outer wall of the bent rod 3052, the first sleeve 3053 is made of a hard material, and the outer wall of the first sleeve 3053 is evenly provided with elastic rods 3054, and the end of the elastic rod 3054 away from the first sleeve 3053 is fixedly connected to the second sleeve 3055, and the second sleeve 3055 is made of a flexible dust-absorbing material.

[0050] When an object is placed on the transport roller 303 and is driven by the transport roller 303 to move downward to the inside of the cover plate 3051, the bottom of the object contacts the fixed bar 304, causing shaking, and the top of the object contacts the second sleeve 3055. Objects of different heights are squeezed against the elastic rod 3054 through the second sleeve 3055 to keep the object stable and prevent it from tipping over. Debris and dust on the top of the object are adsorbed by the surface of the second sleeve 3055, pre-processing small impurities on the surface of the object and reducing dust from falling on the stage 1 and affecting the measurement.

[0051] The placing component 306 includes a driving block 3061, the top of the driving block 3061 is fixedly connected to the top of the collecting shell 302, the inner wall of the driving block 3061 is evenly provided with moving rods 3062, the outer wall of the moving rod 3062 is slidably connected to the inner wall of the driving block 3061, and the end of the moving rod 3062 away from the driving block 3061 is provided with a limiting plate 3063, the top of the limiting plate 3063 is fixedly connected to the bottom of the collecting shell 302, the inner wall of the limiting plate 3063 is sleeved with the outer wall of the moving rod 3062, and the end of the moving rod 3062 away from the limiting plate 3063 is fixedly connected to the push rod 3064. To keep the moving rod 3062 able to move horizontally stably, a support rod 3065 is symmetrically provided on the side of the push rod 3064 away from the moving rod 3062, and a connecting rod 3066 is slidably connected to the side of the push rod 3064 close to the support rod 3065. The outer wall of the connecting rod 3066 is slidably connected to the outer wall of the support rod 3065. The connecting rod 3066 is a combination of a straight rod and a curved rod 3052 connected in a rotating manner. When contacting an object, the straight rod is pressed by the object, thereby driving the straight rod to contact the push rod 3064, and then the curved rod 3052 is driven by the support rod 3065 to approach each other, clamping the object from the side, so that the object remains facing the lens for measurement.

[0052] When the object falls from the transmission roller 303 to the surface of the worktable 1, the driving block 3061 drives the moving rod 3062 to move outward, so that the object contacts the connecting rod 3066. Under the adjustment of the connecting rod 3066, the object moves toward the lens and is pushed directly under the lens for measurement, avoiding the object being placed randomly and loading, which requires manual adjustment and increases the workload of workers.

[0053] The specific workflow is as follows:

[0054] During operation, the base 301 drives the bottom of the collection shell 302 to contact the top of the stage 1, and then places the object to be measured on the transmission roller 303. The object slides down along the transmission roller 303 due to gravity. When the object passes through the squeezing component 305, the fixing bar 304 drives the object to shake and buffers the speed of the object to prevent it from sliding directly from the transmission roller 303, causing the object to fall quickly onto the stage 1 and damage the stage 1. The squeezing component 305 cleans the debris and dust on the top of the object and prevents the object from tipping over. After the object is placed on the stage 1, the placing component 306 pushes the object toward the vision measuring instrument 202 so that the regularly shaped object is placed facing the vision measuring instrument 202.

[0055] The vision measuring instrument 202 then automatically scans and measures the object. After a period of use, dust may accumulate on the lens of the vision measuring instrument 202 due to static electricity. At this time, the telescopic column 203 drives the wiping assembly 204 to rotate 180 degrees, aligning the wiping assembly 204 with the lens position. The lens is inserted into the wiping assembly 204. The wiping assembly 204 contains alcohol, which cleans the dust on the lens and eliminates a certain amount of static electricity. The lens is then dried by the drying assembly 207 and removed, and the wiping assembly 204 returns to its original position.
