Description

Technical Field

[0001] The present invention relates to the technical field of photoelectric measurement, and in particular to a high-speed 3D camera module for photoelectric measurement. Background Art

[0002] A high-speed 3D camera is an advanced optoelectronic measurement tool that is capable of capturing the geometry and texture of a target surface in an extremely short time. Its principle is based on a combination of high-resolution image acquisition and fast signal processing technology, enabling it to acquire object data in three-dimensional space at a speed of hundreds to thousands of frames per second.

[0003] These cameras typically utilize advanced technologies such as structured light, time encoding, or multi-view imaging to achieve high-precision measurement and rapid data acquisition. High-speed 3D cameras are increasingly being used in fields such as industrial manufacturing, robotic navigation, biomedicine, and virtual reality, providing critical support for real-time inspection, motion analysis, and precise measurement. They can effectively address the challenges of complex environments and rapid motion, making them an indispensable technical tool in modern optoelectronic measurement and image processing. The measurement principle of high-speed 3D cameras typically involves the use of structured light or time-of-flight technology. Structured light cameras create three-dimensional images by emitting a structured light source, such as laser or LED light, and measuring changes in light reflection. Time-of-flight cameras measure the time it takes for light to reflect from the camera to the object's surface and back to the camera, thereby determining distance. These technologies, combined with high-speed sensors and processors, can capture the three-dimensional shape and motion of an object in real time. When measuring the size of a part, the part is placed on an inspection table, where a robotic arm drives the high-speed 3D camera to scan the part. The camera is then reset, and the part's dimensional data is displayed and analyzed on a display connected to the camera, allowing for faster and more accurate measurement of the part's dimensions.

[0004] Currently, when using high-speed 3D cameras to measure the dimensions of parts, the existing technology usually places the part on a test table, and the high-speed 3D camera, which emits lasers, moves to scan the part, and displays and analyzes the part's dimensional data on a display. However, when measuring a new part, the part needs to be removed and replaced first, which is a cumbersome operation and easily affects measurement efficiency. Therefore, this does not meet existing needs. In response to this, we propose a high-speed 3D camera module for photoelectric measurement. Summary of the Invention

The number of the elastic sheets is the same as the number of the ratchets, and the elastic sheets respectively contact the ratchets one by one.

[0014] As an optional solution for a high-speed 3D camera module for photoelectric measurement described in the present invention, when the positioning rod is located in the arc groove, the top of the positioning rod is flush with the upper surface of the measuring platform, the part body is configured as a circular ring, the four part bodies are respectively placed above the four positioning components, and the positioning rod is located in the ring in the middle of the part body.

[0015] As an optional solution of a high-speed 3D camera module for photoelectric measurement described in the present invention, the four positioning components are respectively located at the junction of the arc groove and the widened groove, the junction of the widened groove and the narrowed groove, the junction of the narrowed groove and the arc groove, and the middle of the arc groove.

[0016] The present invention has the following beneficial effects:

[0017] 1. This high-speed 3D camera module for photoelectric measurement has a movable arm that slides along a track, driving the camera body toward the measuring table. Simultaneously, a limit assembly is provided to cause the gear and column to rotate relative to each other, thereby causing the rack to mesh and drive the gear to rotate while the column remains stationary relative to the body. This keeps the measuring table and the part body on it stationary, and the camera body emits a laser to scan and measure one of the part bodies on the measuring table.

[0018] After the measurement is completed, the movable arm drives the camera body and the rack to move back and reset, and the limit assembly is set again to make the gear and the column rotate synchronously. The engagement of the gear and the rack drives the column to rotate, so that the measuring table drives the part body on it to rotate, so that the measured part body is away from the scanning measurement area below the camera body, which is convenient for removing it from the measuring table and placing a new part body to be measured in the vacant position on the measuring table. At the same time, another part body rotates with the measuring table to the bottom of the camera body, and the above operation is repeated to continue measuring the size of the part body, avoiding the operation of taking and loading materials at the scanning measurement position, thereby improving measurement efficiency.

[0019] 2. This high-speed 3D camera module for photoelectric measurement is slidably inserted into a slot via an insertion rod, so that the positioning assembly rotates along with the rotation of the measuring platform. When the rotating measuring platform drives the positioning rod to slide in the widened slot, the two positioning rods are moved away from each other by the rebound force of the spring. Moreover, as the depth of the widened slot gradually decreases, the two positioning rods move away from each other and rise upward, so that both positioning rods abut against the inner wall of the part body, fixing the part body on the measuring platform, thereby minimizing the deviation of the part body from the scanning measurement area of ​​the camera body. In addition, the larger the inner diameter of the part body, the greater the degree of spring rebound, making the positioning assembly suitable for parts with different inner diameters.

[0020] When the measuring table drives the positioning rod to slide in the narrowed groove, the narrowed groove squeezes the positioning rod and the spring is compressed, so that the positioning rod is separated from the inner wall of the part body and simultaneously drops and retracts to the inside of the measuring table, thereby releasing the fixing effect on the part body; when the positioning rod slides in the arc groove, the positioning rod retracts into the measuring table and does not fix the part body thereon, thereby facilitating the removal of the measured part body from the measuring table at this stage and the placement of a new part body to be measured, so that when the measuring table drives the part body to rotate and when the camera body performs scanning and measurement on the part body, it is convenient to fix the part body on the measuring table, and it is not easy for the position of the part body to deviate from the scanning and measurement area, thereby improving the accuracy of the camera body's measurement of the part body.

[0021] 3. In this high-speed 3D camera module for photoelectric measurement, when the moving arm drives the camera body forward for measurement, the rack engages and drives the gear to rotate, causing the gear to rotate the outer ring. The outer ring presses the ratchet teeth, causing the ratchet teeth to rotate along the direction of the ratchet groove and squeeze the elastic sheet. Because the resistance of the damping bearing on the column is greater than the resistance of the ratchet teeth on the outer ring, the gear drives the outer ring to rotate while the inner ring and the column remain stationary. As a result, when the camera body measures the part body, the measuring platform and the part body on it remain stationary.

[0022] When the movable arm drives the rack to move back and reset, the rack drives the gear to rotate, and the ratchet is engaged in the ratchet groove against the direction of the ratchet groove, so that the outer ring drives the inner ring to rotate synchronously through the ratchet, thereby making the rotating gear drive the column and the measuring platform to rotate synchronously, making it easy to control the relative rotation or synchronous rotation of the column and the gear, thereby making it easy to control the rotation of the measuring platform.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1: This example aims to solve the problem that when using a high-speed 3D camera to measure the dimensions of a part in the prior art, the part is usually placed on a test table, and the high-speed 3D camera that emits laser light moves to scan the part, and the dimensional data of the part is displayed and analyzed on the display. However, when measuring a new part again, the part needs to be removed and replaced first, which is a cumbersome operation and easily affects the measurement efficiency. Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 and Figure 9 A high-speed 3D camera module for photoelectric measurement includes a body 100, a robotic arm 110 arranged on the side of the body 100, and a camera body 120 arranged on the outside of the robotic arm 110. The camera body 120 is configured as a high-speed 3D camera. The robotic arm 110 includes a track 111 installed on the outside of the body 100 and a moving arm 112 slidably arranged on the upper side of the track 111. The robotic arm 110 is a technical means well known to those skilled in the art and will not be described in detail here. The camera body 120 is fixedly set at the end of the moving arm 112.

[0035] A measuring platform 130 is rotatably provided at the top of the body 100. The measuring platform 130 is configured as a frustum, and the camera body 120 is located above the measuring platform 130. A column 140 is fixedly installed on the lower side of the measuring platform 130. The center of the column 140 and the measuring platform 130 are on the same vertical line. The lower end of the column 140 is rotatably inserted into the inner side of the body 100. The body 100 is configured as a cylinder with an open upper end. An annular groove is provided on the inner side of the measuring platform 130. The upper end of the body 100 is slidably inserted into the annular groove inside the measuring platform 130. A damping bearing 141 is sleeved on the lower end of the column 140. The column 140 is fixedly fitted with the inner ring of the damping bearing 141, and the body 100 is fixedly fitted with the outer ring of the damping bearing 141.

[0036] A limit assembly 150 is sleeved on the middle part of the column 140, and a gear 160 is sleeved on the outside of the limit assembly 150. The limit assembly 150 is used to control the relative rotation or synchronous rotation of the column 140 and the gear 160. A rack 170 is fixedly installed on the outside of the movable arm 112. The middle part of the rack 170 is inserted into the side of the body 100 and meshes with the gear 160. A part body 180 is placed on the upper side of the measuring platform 130. The part body 180 is configured as a ring-shaped workpiece. A positioning assembly 190 is provided on the inside of the measuring platform 130. The positioning assembly 190 fixes the part body 180 under the camera body 120, so that the camera body 120 can emit a laser to scan the part body 180, thereby measuring the size of the part body 180.

[0037] In this embodiment, the movable arm 112 slides along the track 111, so that the movable arm 112 drives the camera body 120 to move toward the measuring platform 130. At the same time, the limit assembly 150 causes the gear 160 and the column 140 to rotate relative to each other, thereby causing the rack 170 to mesh and drive the gear 160 to rotate while the column 140 remains stationary relative to the body 100. This keeps the measuring platform 130 and the component body 180 thereon stationary, and the camera body 120 emits a laser to scan and measure one of the component bodies 180 on the measuring platform 130.

[0038] After the measurement is completed, the movable arm 112 drives the camera body 120 and the rack to move back and reset, and again through the setting of the limit assembly, the gear 160 and the column 140 rotate synchronously, and the engagement of the gear 160 and the rack 170 drives the column 140 to rotate, so that the measuring table 130 drives the part body 180 thereon to rotate, so that the measured part body 180 is away from the scanning measurement area below the camera body 120, which is convenient for removing it from the measuring table 130 and placing a new part body 180 to be measured in the vacant position on the measuring table 130. At the same time, another part body 1 80 rotates with the measuring table 130 to the bottom of the camera body 120, and repeats the above operation to continue measuring the size of the part body 180, avoiding the operation of taking and loading materials at the scanning and measuring position, thereby improving the measurement efficiency and solving as much as possible the problem that when using a high-speed 3D camera to measure the size of a part in the prior art, the part is usually placed on the inspection table, and the high-speed 3D camera that emits laser moves to scan the part, and the size data of the part is displayed and analyzed through the display. However, when measuring a new part again, the part needs to be removed and replaced first, and the operation steps are cumbersome, which easily affects the measurement efficiency.

[0039] The second embodiment is intended to solve the problem that when the measuring platform 130 drives the part body 180 to rotate and the camera body 120 performs scanning measurement on the part body 180, it is inconvenient to fix the part body on the measuring platform 130, which easily causes the position of the part body 180 to deviate from the scanning measurement area, thereby easily affecting the accuracy of the camera body 120 measuring the part body 180. This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 The positioning assembly 190 includes a positioning rod 191 arranged on the inner side of the measuring platform 130, a spring 192 connected between the positioning rods 191, an insertion rod 193 slidably inserted on the side of the positioning rod 191, and a sliding rod 194 fixedly installed at the lower end of the positioning rod 191. The number of positioning assemblies 190 is set to four, and the four positioning assemblies 190 are evenly arranged on the side of the measuring platform 130 in an annular direction. The number of positioning rods 191 is set to two, and the two ends of the spring 192 are fixedly connected to the two positioning rods 191 respectively. A slot 195 is opened on the inner side of the measuring platform 130. The number of slots 195 is the same as that of the insertion rod 193, and the insertion rod 193 is slidably inserted in the slot 195 respectively, and a slider 1931 is installed at the end of the insertion rod 193. The slider 1931 is set to a "T" shape. The slider 1931 is slidably inserted on the inner side of the positioning rod 191 to prevent the insertion rod 193 from separating from the positioning rod 191.

[0040] A slide groove 200 is provided on the top of the body 100, and the slide groove 200 slides with the positioning rod 191 and the slide rod 194. The lower end of the positioning rod 191 and the slide rod 194 are both slidably inserted into the slide groove 200. The slide groove 200 includes an arc groove 201 provided on the top of the body 100, a widening groove 202 connected to one end of the arc groove 201, and a narrowing groove 203 connected to the widening groove 202; the narrowing groove 203 is connected to the other end of the arc groove 201, and the center of the arc groove 201, the center of the body 100 and the center of the measuring platform 130 are all on the same vertical line. The arc groove 201 is set to a groove body with the same depth. The depth of the widening groove 202 decreases as the width increases, and the depth of the narrowing groove 203 increases as the width decreases.

[0041] When the positioning rod 191 is located in the arc groove 201, the top of the positioning rod 191 is flush with the upper surface of the measuring platform 130, and the spring 192 is in a compressed state. The part body 180 is set to a circular ring shape. The four part bodies 180 are respectively placed above the four positioning components 190, and the positioning rod 191 is located in the ring in the middle of the part body 180. The four positioning components 190 are respectively located at the junction of the arc groove 201 and the widened groove 202, the junction of the widened groove 202 and the narrowed groove 203, the junction of the narrowed groove 203 and the arc groove 201, and the middle of the arc groove 201. The camera body 120 is located above the junction of the widened groove 202 and the narrowed groove 203, and the moving rack 170 drives the measuring platform 130 to rotate 90 degrees by engaging with the gear 160, so that the measuring platform 130 drives the four positioning components 190 and the part body 180 thereon to pass through the lower side of the camera body 120 in sequence.

[0042] In this embodiment, the insertion rod 193 is slidably inserted into the slot 195, so that the positioning assembly 190 rotates with the rotation of the measuring platform 130. When the rotating measuring platform 130 drives the positioning rod 191 to slide in the widened groove 202, the two positioning rods 191 are moved away from each other by the rebound force of the spring 192. Moreover, since the depth of the widened groove 202 gradually decreases, the two positioning rods 191 move away from each other and rise upward, so that the two positioning rods 191 both contact the inner wall of the part body 180, fixing the part body 180 on the measuring platform 130, thereby avoiding the part body 180 and the scanning measurement area of ​​the camera body 120 from offsetting as much as possible. Moreover, the larger the inner diameter of the part body 180, the greater the degree of rebound of the spring 192, so that the positioning assembly 190 is suitable for part bodies 180 with different inner diameters.

[0043] When the measuring platform 130 drives the positioning rod 191 to slide in the narrowed groove 203, the narrowed groove 203 squeezes the positioning rod 191, and the spring 192 is compressed, so that the positioning rod 191 is separated from the inner wall of the part body 180 and drops back to the inside of the measuring platform 130, releasing the fixing effect on the part body 180; when the positioning rod 191 slides in the arc groove 201, the positioning rod 191 is retracted into the measuring platform 130 and does not fix the part body thereon, thereby facilitating the removal of the measured part body 180 from the measuring platform 130 at this stage and the placement of a new part body 180 to be measured, so that when the measuring platform 130 drives the part body 180 to rotate and when the camera body 120 performs scanning and measurement on the part body 180, it is convenient to fix the part body on the measuring platform 130, and it is not easy for the position of the part body 180 to deviate from the scanning and measurement area, thereby improving the accuracy of the measurement of the part body 180 by the camera body 120.

[0044] Example 3: This example aims to solve the problem that it is difficult to control the relative rotation or synchronous rotation of the column 140 and the gear 160, thereby making it difficult to control the rotation of the measuring platform 130. This example is an improvement made on the basis of Example 1. For details, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The outer side of the limiting assembly 150 is sleeved with a gear 160. The limiting assembly 150 includes an inner ring 151 fixedly sleeved on the outer side of the column 140, an outer ring 152 fixedly inserted on the inner side of the gear 160, a ratchet 153 arranged on the side of the inner ring 151 by rivets, an elastic sheet 154 fixedly mounted on the side of the inner ring 151 and in contact with the ratchet 153, and a ratchet groove 155 opened on the side of the outer ring 152 for clamping the ratchet 153. The number of ratchet teeth 153 is set to be several, and the several ratchet teeth 153 are evenly arranged on the side of the inner ring 151 in the circumferential direction. The number of elastic sheets 154 is the same as the number of ratchet teeth 153, and the elastic sheets 154 respectively in contact with the ratchet teeth 153 one by one. The number of ratchet grooves 155 is set to be several, and the several ratchet grooves 155 are evenly opened on the inner side of the outer ring 152 in the circumferential direction, and the ends of the ratchet teeth 153 are clamped in the corresponding ratchet grooves 155.

[0045] In this embodiment, when the movable arm 112 drives the camera body 120 forward for measurement, the rack 170 meshes with the gear 160 to rotate, causing the gear 160 to rotate the outer ring 152. The outer ring 152 presses the ratchet teeth 153, causing the ratchet teeth 153 to rotate along the direction of the ratchet groove 155 and press the elastic sheet 154. Because the resistance of the damping bearing 141 on the column 140 is greater than the resistance of the ratchet teeth 153 on the outer ring 152, the gear 160 drives the outer ring 152 to rotate while the inner ring 151 and the column 140 remain stationary. As a result, when the camera body 120 measures the component body 180, the measuring platform 130 and the component body 180 thereon remain stationary.

[0046] When the movable arm 112 drives the rack 170 to move backward and reset, the rack 170 drives the gear 160 to rotate, and the ratchet 153 is engaged in the ratchet groove 155 against the direction of the ratchet groove 155, so that the outer ring 152 drives the inner ring 151 to rotate synchronously through the ratchet 153, thereby making the rotating gear 160 drive the column 140 and the measuring platform 130 to rotate synchronously, so as to facilitate the control of the relative rotation or synchronous rotation of the column 140 and the gear 160, thereby facilitating the control of the rotation of the measuring platform 130.

[0047] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
