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 has the ability to capture the geometry and texture of a target surface in a very short time. Its principle is based on combining high-resolution image acquisition with fast signal processing technology, and can acquire object data in three-dimensional space at a speed of hundreds to thousands of frames per second.

[0003] These cameras usually use advanced technologies such as structured light, time coding or multi-view imaging to achieve high-precision measurement and fast data acquisition. In the fields of industrial manufacturing, robot navigation, biomedicine and virtual reality, the application of high-speed 3D cameras is becoming more and more extensive, providing key support for real-time detection, motion analysis and precise measurement. It can effectively cope with the challenges of complex environments and fast movements, and has become one of the indispensable technical tools in modern optoelectronic measurement and image processing. The measurement principle of high-speed 3D cameras usually involves the use of structured light or time-of-flight technology. Structured light cameras create three-dimensional images by emitting structured light sources such as laser or LED light and measuring the changes in light reflection; time-of-flight cameras measure the time it takes for light to be emitted from the camera to reflect back to the camera from the surface of the object, thereby determining the distance. These technologies, combined with high-speed sensors and processors, can capture the three-dimensional shape and movement of objects in real time. When measuring the size of a part, the part needs to be placed on the inspection table, and the high-speed 3D camera is driven by a robotic arm to move and scan the part. The high-speed 3D camera is then reset, and the size data of the part is displayed and analyzed through a display connected to the high-speed 3D camera, so as to measure the size of the part more quickly and accurately.

[0004] At present, when the existing technology uses a high-speed 3D camera to measure the size of a part, the part is usually placed on a test table, and the high-speed 3D camera that emits a laser moves to scan the part, and the size data of the part is displayed and analyzed on a display.

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

[0017] 1. The high-speed D camera module for photoelectric measurement has a moving arm that slides along a track, so that the moving arm drives the camera body to move toward the direction close to the measuring table. At the same time, through the setting of the limit assembly, the gear and the column rotate relative to each other, so that the rack drives the gear to rotate through meshing while the column remains stationary relative to the body, so that the measuring table and the part body thereon remain 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 mobile 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 thereon 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 picking and loading materials at the scanning measurement position, thereby improving the measurement efficiency.

[0019] 2. The high-speed D camera module for photoelectric measurement is inserted into the slot by sliding the insertion rod, so that the positioning assembly rotates with the rotation of the measuring platform. When the rotating measuring platform drives the positioning rod to slide in the widening groove, the two positioning rods are moved away from each other by the rebound force of the spring. Moreover, since the depth of the widening groove gradually decreases, the two positioning rods are moved away from each other and raised upward, so that the two positioning rods are both against the inner wall of the part body, and the part body is fixed on the measuring platform, so as to avoid the part body and the scanning measurement area of ​​the camera body from offsetting as much as possible. Moreover, the larger the inner diameter of the part body, the greater the degree of spring rebound, so that the positioning assembly is suitable for part bodies with different inner diameters.

[0020] When the measuring table drives the positioning rod to slide in the narrowing groove, the narrowing 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 descends and retracts to the inner side 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 without fixing the part body thereon, thereby facilitating the removal of the measured part body from the measuring table at this stage and placing a new part body to be measured, so that when the measuring table drives the part body to rotate and 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 the high-speed D camera module for photoelectric measurement, when the moving arm drives the camera body to move forward for measurement, the rack drives the gear to rotate through meshing, so that the gear drives the outer ring to rotate, and the outer ring squeezes the ratchet, so that the ratchet rotates along the direction of the ratchet groove and squeezes the elastic sheet. Since the resistance of the damping bearing to the column is greater than the resistance of the ratchet to the outer ring, the gear drives the outer ring to rotate while the inner ring and the column remain stationary, so that when the camera body measures the part body, the measuring platform and the part body thereon remain stationary;

[0022] When the moving arm drives the rack to move backward 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, which is convenient for controlling the relative rotation or synchronous rotation of the column and the gear, thereby facilitating the control of the rotation of the measuring platform.

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 creative work are within the scope of protection of the present invention.

[0034] Embodiment 1: This embodiment aims to promote the solution of the problem that when a high-speed 3D camera is used to measure the size 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 moves to scan the part, and the size data of the part is displayed and analyzed on a 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. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Fig. 9 A high-speed 3D camera module for photoelectric measurement includes a body 100, a mechanical arm 110 arranged on the side of the body 100, and a camera body 120 arranged on the outside of the mechanical arm 110. The camera body 120 is configured as a high-speed 3D camera. The mechanical 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 mechanical arm 110 is a technical means well known to technicians in this field and will not be described in detail here. The camera body 120 is fixedly arranged at the end of the moving arm 112.

[0035] A measuring table 130 is rotatably provided at the top of the body 100. The measuring table 130 is set as a round table, and the camera body 120 is located above the measuring table 130. A column 140 is fixedly installed on the lower side of the measuring table 130. The center of the column 140 and the measuring table 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 set as a cylindrical shape with an open upper end. An annular groove body is opened on the inner side of the measuring table 130. The upper end of the body 100 is slidably inserted into the annular groove body on the inner side of the measuring table 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 outer side 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 outer side 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 set as an annular workpiece. A positioning assembly 190 is set on the inner side 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 in the direction close to the measuring platform 130. At the same time, through the setting of the limit assembly 150, the gear 160 and the column 140 rotate relative to each other, so that the rack 170 drives the gear 160 to rotate through meshing while the column 140 remains stationary relative to the body 100, so that the measuring platform 130 and the part body 180 thereon remain stationary, and the camera body 120 emits a laser to scan and measure one of the part bodies 180 on the measuring platform 130;

[0038] After the measurement is completed, the moving arm 112 drives the camera body 120 and the rack to move back and reset, and the gear 160 and the column 140 are rotated synchronously by setting the limit assembly again. 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 also convenient for 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 picking up and loading materials at the scanning and measuring position, thereby improving the measurement efficiency and solving as much as possible the problem that when the prior art uses a high-speed 3D camera to measure the size of a part, 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] Embodiment 2: This 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 measurement accuracy of the camera body 120 on the part body 180. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Fig. 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 on 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. 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 is slidably matched with the positioning rod 191 and the sliding rod 194. The lower end of the positioning rod 191 and the sliding rod 194 are both slidably inserted in 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 meshing 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 widening 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 widening 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, and the part body 180 is fixed on the measuring platform 130, so as to avoid 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 narrowing groove 203, the narrowing 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 simultaneously descends and retracts to the inner side of the measuring platform 130, thereby 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 the part body thereon is not fixed, thereby facilitating the removal of the measured part body 180 from the measuring platform 130 at this stage, and placing 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 camera body 120 measuring the part body 180.

[0044] Embodiment 3: This embodiment is intended to facilitate solving the problem that it is inconvenient to control the relative rotation or synchronous rotation of the column 140 and the gear 160, and thus it is inconvenient to control the rotation of the measuring platform 130. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A gear 160 is sleeved on the outer side of the limiting component 150. The limiting component 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 rotatably arranged on the side of the inner ring 151 by rivets, an elastic sheet 154 fixedly installed 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 uniformly arranged on the side of the inner ring 151 in an annular 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 uniformly opened on the inner side of the outer ring 152 in an annular direction, and the ends of the ratchet teeth 153 are clamped in the corresponding ratchet grooves 155.

[0045] In this embodiment: when the moving arm 112 drives the camera body 120 to move forward for measurement, the rack 170 drives the gear 160 to rotate through meshing, so that the gear 160 drives the outer ring 152 to rotate, and the outer ring 152 squeezes the ratchet 153, so that the ratchet 153 rotates along the direction of the ratchet groove 155 and squeezes the elastic sheet 154. Since the resistance of the damping bearing 141 to the column 140 is greater than the resistance of the ratchet 153 to 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, so that when the camera body 120 measures the part body 180, the measuring platform 130 and the part 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, so that the rotating gear 160 drives 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 article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[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 the scope of protection of the present invention.
