Description

Technical Field

[0001] The invention relates to the technical field of image measurement and discloses a multi-angle detection type image measuring instrument. Background Art

[0002] Image measuring instruments are a type of high-precision inspection equipment that is widely used in industrial production. They are mainly used to measure parameters such as the size, shape, and position of parts. Existing image measuring instruments usually achieve high-precision measurement by photographing and processing images of parts. The basic process is placing parts, photographing images, image processing, and data analysis. However, if the part to be measured is an irregular shape, and there are multiple inclined surfaces or sides on the part that need to be inspected, when the image inspector completes the inspection of one side of the part, if it continues to inspect the side or inclined surface of the part, it is necessary to adjust the placement of the part and reposition it to complete the photographing and measurement of the side of the part, which prolongs the inspection cycle of a single part, increases the complexity of the operation, and reduces the inspection efficiency. At the same time, if the shape of the part cannot support its inclined surface facing upward, the part will not be able to complete all inspections. Therefore, it is necessary to develop a multi-angle inspection image measuring instrument that can autonomously and efficiently adjust the position of the part inspection surface.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1 -Attached Figure 8 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0044] Example 1: When an existing image measuring instrument measures a cylinder with holes on the side, if there are holes on the side of the part to be inspected, the placement state of the part needs to be adjusted and repositioned during the shooting inspection process of the measured part in order to achieve the purpose of detecting the holes on the side of the measured part, which prolongs the inspection time of a single part, increases the complexity of the part measurement operation, and reduces the inspection efficiency of the part.

[0045] A multi-angle detection image measuring instrument, please refer to Figure 1-Figure 4As shown, it includes: a mounting base 1, on which an industrial camera is arranged; a support ring 2, which is rotatably connected to the mounting base 1, and a rotating frame 3 is rotatably connected inside the support ring 2, a connecting shell 4 is fixedly connected to the upper side of the rotating frame 3, and a through hole is arranged on the lower side of the connecting shell 4, and the connecting shell 4 is tilted in different directions and at different angles through the swing of the support ring 2 and the circumferential rotation of the rotating frame 3; a fixing frame 5, which is fixed to the through hole of the connecting shell 4, and a ring light 6 is ball-connected to the fixing frame 5; a control mechanism, which is arranged in the mounting base 1 and is used to control the rotation angle of the support ring 2 and the rotating frame 3, so as to change the tilt direction and tilt angle of the connecting shell 4; an auxiliary positioning mechanism, which is arranged on the upper side of the connecting shell 4 and is used to assist the industrial camera on the mounting base 1 in positioning the part to be measured, and the axis of the ring light 6 coincides with the axis of the industrial camera on the mounting base 1, so as to make the light range of the ring light 6 be located at the industrial camera on the mounting base 1 Within the observation range, the control mechanism includes: a motor 201, which is fixed in the mounting base 1, and the output shaft of the motor 201 is fixed with a connecting shaft 202, and the connecting shaft 202 is rotatably connected with a rotating rod 203, and the rotating rod 203 is rotatably connected to the rotating frame 3. The output shaft of the motor 201 controls the rotation of the rotating frame 3 through the connecting shaft 202 and the rotating rod 203, thereby changing the tilt direction of the connecting shell 4; an electric push rod 204, which is hinged in the mounting base 1, and the telescopic end of the electric push rod 204 is hinged to the support ring 2. The electric push rod 204 controls the rotation of the support ring 2 by moving its telescopic end, thereby changing the tilt angle of the connecting shell 4; an angle stabilizing component, which is arranged on the ring light 6, and is used for backlighting parts to be measured with different tilt angles. The rotation axis of the connecting shaft 202 and the rotating rod 203 is located in the same horizontal plane as the rotation axis of the mounting base 1 and the support ring 2, so as to enable the connecting shell 4 to rotate in multiple directions.

[0046] In the above scheme, the problem that the image measuring instrument cannot actively control the deflection of the measured part and cannot continuously shoot and measure the sides of irregular parts at multiple different angles is solved. A control panel is set on the mounting seat 1, and the connecting shell 4 is located between the rotating frame 3 and the industrial camera on the mounting seat 1. The middle part of the upper side of the connecting shell 4 is set as a glass plate, which is used to make the light illuminate the measured part from bottom to top, so that the measured part photographed by the industrial camera on the mounting seat 1 shows a clear edge contour line. The position of the industrial camera on the mounting seat 1 can be adjusted up and down, so that parts of different sizes taken by industrial addition can be clearly displayed. The fixed frame 5 and the ring light 6 are set at the spherical joint surface. There are several ball bearings. No matter how the connecting shell 4 is tilted, the ring light 6 always remains facing upward, ensuring that the parts photographed by the industrial camera always have a stable backlight. The connecting shell 4 rotates in the support ring 2 through two rotating frames 3 that are mirrored on the left and right. The support ring 2 remains relatively parallel to the connecting shell 4 through the two rotating frames 3. The support ring 2 stably supports the connecting shell 4 through the two rotating frames 3. The intersection of the connecting shaft 202 and the rotating axis of the rotating rod 203 is located at the center of the support ring 2, so that the two rotating frames 3 in the support ring 2 are always in a mirror distribution state. The ring light 6, the motor 201 and the electric push rod 204 are all electrically connected to the control panel.

[0047] Workflow: First, the operator places the part to be measured on the glass plate of the connecting shell 4, and then moves and positions the part at the center of the glass plate on the connecting shell 4 through the auxiliary positioning mechanism. Then, the operator starts the ring light 6, and the industrial camera on the mounting seat 1 takes pictures of the part and performs data analysis to complete the measurement of the upper side of the part. If it is necessary to measure the side specifications of the part, the control panel starts the electric push rod 204, the telescopic end of the electric push rod 204 contracts, and the telescopic end of the electric push rod 204 drives the support ring 2 to rotate counterclockwise (from front to back), and the support ring 2 drives the rotating The movable frame 3 and the connecting shell 4 deflect to the lower left, and the side orientation of the part on the connecting shell 4 becomes inclined upward, the control panel turns off the electric push rod 204, and at the same time the control panel starts the motor 201, the output shaft of the motor 201 drives the connecting shaft 202 to rotate, the connecting shaft 202 rotates on the support ring 2 through the rotating rod 203 and the two rotating frames 3, and the two rotating frames 3 drive the connecting shell 4 to rotate synchronously, when the part on the connecting shell 4 rotates a fixed angle (at this time the inclined surface of the part to be detected becomes an upward state, and the industrial camera can shoot and measure the inclined surface of the part), the control panel turns off the motor 201.

[0048] During the downward deflection of the connecting shell 4, the angle stabilizing component controls the annular light 6 to rotate on the fixing frame 5, and the balls between the fixing frame 5 and the annular light 6 assist the relative rotation of the two, so that the light emitted by the annular light 6 is always facing the industrial camera on the mounting seat 1, reducing the possibility of light tilting and interfering with the accurate detection of the part data measured by the industrial camera on the mounting seat 1. If the connecting shell 4 tilts to the left from top to bottom, the industrial camera on the mounting seat 1 shoots and measures the right side of the part, and the auxiliary positioning mechanism releases the contact with the right side of the measured part, which is convenient for the industrial camera on the mounting seat 1 to shoot and measure the right side of the part, ensuring the comprehensiveness of the data shot on the side of the part. Then the control panel controls the motor 201 and the electric push rod 204 to make the support ring 2 and the rotating frame 3 repeat the above rotation operation, and complete the shooting measurement of all sides of the part in turn. Finally, after the control panel controls the support ring 2 and the rotating frame 3 to rotate and reset through the motor 201 and the electric push rod 204, the motor 201 and the electric push rod 204 are both turned off, and the operator controls the auxiliary positioning mechanism to release the positioning of the part, replaces the next part to be measured, and repeats the above measurement operation on the part. When the measurement of all parts is completed, the operator turns off the ring light 6 through the control panel. At this point, all parts in the device are restored to their initial positions and wait for the next use.

[0049] Please refer to Figure 3 and Figure 4 As shown, the angle stabilizing component includes: a weight block 301, which is fixed to the lower side of the ring light 6; a magnet block 302, which is fixed to the weight block 301, and an iron plate 303 is fixed to the upper end of the connecting shaft 202. The magnet block 302 and the iron plate 303 are attracted to each other, so that the angle of the ring light 6 does not rotate with the deflection of the connecting shell 4.

[0050] In the above scheme, it is intended to solve the problem that during the inspection process of the parts, the angle of the light emitted by the ring light 6 is easily deflected due to the inclination of the connecting shell 4, resulting in deviations in the specification data of the side of the parts measured by the industrial camera on the mounting seat 1. The weight block 301 is located directly below the ring light 6, and is used to make the light emitted by the ring light 6 always face the industrial camera on the mounting seat 1 through the gravity of the weight block 301, so as to achieve the purpose of ensuring that the angle of the light emitted by the ring light 6 remains unchanged. The projection of the magnet block 302 on the horizontal plane with the moving range of the weight block 301 and the ring light 6 is always located within the projection range of the iron plate 303 on the horizontal plane, so that the magnet block 302 and the iron plate 303 are always in a state of mutual adsorption.

[0051] Working process: in the process of controlling the inclination of the connecting shell 4 by rotating the supporting ring 2 and the rotating frame 3, the rotating rod 203 rotates relative to the two rotating frames 3, and the connecting shaft 202 and the rotating rod 203 rotate relative to each other to adapt to the angle of the inclination direction of the connecting shell 4. At the same time, the connecting shell 4 drives the fixed frame 5 to rotate synchronously. The upward state of the ring light 6 does not change under the combined action of the gravity of the weight block 301 and the attraction between the magnet block 302 and the iron plate 303. After the ring light 6 rotates relative to the fixed frame 5, since the connecting shell 4 is in an inclined state, the distance between the magnet block 302 and the iron plate 303 is reduced, and the attraction between the magnet block 302 and the iron plate 303 is increased. The upward state of the ring light 6 is more stable, and the light emitted by the ring light 6 does not produce inclination. After the inclination angle and direction of the connecting shell 4 are adjusted, the device can quickly shoot and measure the parts.

[0052] Please refer to Figure 2 , Figure 3 and Figure 5-Figure 7 As shown, the auxiliary positioning mechanism includes: circumferentially distributed sliding plates 401, which are all slidably connected to the upper side of the connecting shell 4, the sliding plates 401 are slidably connected to the squeezing plates 402, and springs are fixed between the squeezing plates 402 and the adjacent sliding plates 401, and the connecting shell 4 is provided with screws that are squeezed and matched with the adjacent sliding plates 401. The circumferentially distributed squeezing plates 402 jointly assist in positioning the part to be measured; a tilt detection component is arranged in the rotating frame 3, which is used to detect the tilt direction of the connecting shell 4 and release the squeezing plates 402. The inclination detection component includes: circumferentially distributed guide shells 501, the number of which is the same as that of circumferentially distributed sliding plates 401, which are all fixedly connected to the connecting shell 4, and the guide shells 501 are slidably connected with sliding blocks 502, the sliding blocks 502 are fixedly connected with springs, the springs on the sliding blocks 502 are squeezed and matched with the adjacent guide shells 501, the sliding blocks 502 are fixedly connected with pull ropes 503, the pull ropes 503 are fixedly connected to the adjacent squeezing plates 402, and the pull ropes 503 penetrate the adjacent guide shells 501 and the adjacent sliding plates 401.

[0053] In the above scheme, it is intended to solve the problem that when the part is measured at an angle, the side of the part is disturbed by the positioning device, resulting in an incomplete range of the part photographed by the industrial camera on the mounting seat 1. The gravity of the sliding block 502 is greater than the maximum elastic force of the spring connected to the extrusion plate 402, so that the extrusion of the part on the measured side can be quickly released. The extrusion plate 402 is set to a transparent material for not blocking or refracting the light emitted by the ring light 6. The elastic coefficient of the spring connected to the sliding block 502 is equal to the elastic coefficient of the spring connected to the extrusion plate 402. The pull rope 503 is in a taut state when the connecting shell 4 is not tilted. There are four sliding plates 401, which are respectively located at the four sides of the connecting shell 4.

[0054] Workflow: After the part to be measured is placed on the connecting shell 4, the operator manually moves the four sliding plates 401, and the sliding plates 401 drive the extrusion plates 402 to squeeze the parts around and position the parts, so that the industrial camera can quickly locate the parts. Then the operator turns the screws to fix the four sliding plates 401 to the connecting shell 4. If the connecting shell 4 tilts to the lower left, the sliding blocks 502 on the front and rear sides do not move, and the guide shell 501 on the left tilts to the lower left. The sliding block 502 in the left guide shell 501 slides to the lower left, and the sliding block 502 compresses the spring connected to it, and the left pull rope 503 relaxes. Similarly, the right sliding block 502 slides to the lower left, and the spring connected to the right sliding block 502 loses contact with the adjacent guide shell 501. The right sliding block 502 drives the adjacent extrusion plate 402 to move to the upper right side through the adjacent pull rope 503. The spring connected to the right extrusion plate 402 is compressed, and the right extrusion plate 402 loses contact with the part, which is convenient for the industrial camera on the mounting seat 1 to shoot and measure the right side of the part. When the connecting shell 4 swings back to its original position, the left sliding block 502 moves and resets under the elastic force of the adjacent spring, and the right extrusion plate 402 moves and resets under the elastic force of the adjacent spring. The right extrusion plate 402 drives the right sliding block 502 to move and reset through the adjacent pull rope 503. The above-mentioned tilting and releasing positioning operations are repeated. When the measurement of all sides of the part is completed, the operator loosens the screws, and the four extrusion plates 402 release the positioning of the part. At this point, all parts have returned to their initial positions.

[0055] Example 2: Based on Example 1, please refer to Figure 2 and Figure 5-Figure 8As shown, it also includes: a circumferentially distributed fixing mechanism, which is the same in number as the circumferentially distributed sliding plates 401, and is respectively arranged on adjacent extrusion plates 402, and is used to fix the deflected measuring parts, and the fixing mechanism includes: a connecting slide 601, which is limitedly slidably connected to the adjacent extrusion plates 402, and the upper side of the connecting slide 601 is slidably connected with a sliding support plate 602, and a spring is fixed between the sliding support plate 602 and the adjacent connecting slide 601; a sequential control component, which is the same in number as the circumferentially distributed sliding plates 401, and is arranged on adjacent guide shells 501, and is used to limit the movement sequence of the connecting slide 601 and the sliding support plate 602, and the projection of the inner edge of the circumferentially distributed sliding support plate 602 on the horizontal plane is located on the outer side of the projection of the inner edge of the circumferentially distributed extrusion plate 402 on the horizontal plane, and is used to prevent the sliding support plate 602 from causing damage to the parts. The sequential control component includes: a fixed hydraulic cylinder 701, which is fixedly connected to the adjacent guide shell 501, the telescopic end of the fixed hydraulic cylinder 701 is inserted into the adjacent guide shell 501, the telescopic end of the fixed hydraulic cylinder 701 is squeezed and matched with the adjacent sliding block 502, the fixed hydraulic cylinder 701 is connected with a liquid guide tube 702, the extrusion plate 402 is fixedly connected with an elastic hydraulic cylinder 703 connected with the liquid guide tube 702, the telescopic end of the elastic hydraulic cylinder 703 penetrates the adjacent extrusion plate 402, the telescopic end of the elastic hydraulic cylinder 703 is fixedly connected with a fixed block 704, the sliding support plate 602 is fixedly connected with a connecting rope 705 fixed with the adjacent fixed block 704, the connecting rope 705 penetrates the adjacent connecting slide plate 601, and the connecting slide plate 601 is provided with a guide member slidably connected to the adjacent connecting rope 705, and the fixed hydraulic cylinder 701 and the liquid guide tube 702 are both filled with hydraulic oil.

[0056] In the above scheme, for parts with a high center of gravity, during the tilting of the connecting shell 4, the parts may topple or slide on the glass plate of the connecting shell 4. Taking the connecting slide 601 on the right as an example, the left side of the connecting slide 601 is initially located on the right side of the left side of the extrusion plate 402, so that when the industrial camera is facing the part, the edge of the part can be observed. The gravity of the sliding block 502 is greater than the elastic force of the spring connected to the sliding support plate 602. The distance moved by the fixed block 704 is equal to the sum of the distance moved by the connecting slide 601 and the distance moved downward by the sliding support plate 602. Taking the extrusion plate 402 on the right as an example, the projection of the left edge of the sliding support plate 602 on the horizontal plane is located on the right side of the projection of the left edge of the extrusion plate 402 on the horizontal plane, so that when the extrusion plate 402 squeezes and fixes the part, the sliding support plate 602 does not block the industrial camera from measuring the edge contour of the part. There are four fixing mechanisms, which are respectively located on the four extrusion plates 402.

[0057] Working process: if the connecting shell 4 tilts to the lower left side, the left sliding block 502 slides to the lower left side in the adjacent guide shell 501, the left sliding block 502 compresses the spring connected to it, and the left sliding block 502 pushes the telescopic end of the adjacent fixed hydraulic cylinder 701, the telescopic end of the fixed hydraulic cylinder 701 contracts, and the hydraulic oil in the fixed hydraulic cylinder 701 enters the elastic hydraulic cylinder 703 through the guide tube 702, the telescopic end of the elastic hydraulic cylinder 703 extends and drives the fixed block 704 to move to the right, and the fixed block 704 first drives the connecting slide through the connecting rope 705 Plate 601 and sliding support plate 602 move to the right. After the connecting slide plate 601 moves to the limit on the adjacent extrusion plate 402, the connecting slide plate 601 stops moving and supports the undetected side wall of the part. As the fixed block 704 moves to the right, the fixed block 704 pulls the adjacent sliding support plate 602 downward through the connecting rope 705. The sliding support plate 602 compresses the connected spring, and the sliding support plate 602 squeezes the upper side of the part to fix the part, ensuring that the position of the part does not move, thereby improving the validity of the part data measured by the device.

[0058] When the connecting shell 4 swings back to its initial state, the sliding block 502 moves and resets under the elastic force of the connected spring, the telescopic end of the elastic hydraulic cylinder 703 contracts and drives the fixed block 704 to move and reset, the connecting rope 705 relaxes, and the sliding support plate 602 moves and resets under the elastic force of the connected spring. The sliding support plate 602 contacts the fixed parts, and finally the fixed block 704 drives the connecting slide plate 601 to move and reset. At this point, all parts are restored to their initial positions.

[0059] The basic principles, main features and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions in the specification are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
