Description

Technical Field

[0001] The present invention belongs to the technical field of visual inspection auxiliary equipment, and specifically relates to a displacement adjustment device and an adjustment method thereof for 3D visual inspection. Background Art

[0002] The displacement adjustment device for 3D vision inspection is a precision device used to accurately adjust the position of the camera, sensor or object to be inspected in the 3D vision inspection system to ensure the accuracy and stability of the inspection.

The utility model has a reasonable design. The connection mode of the basket bolt structure formed by the internal threaded tube and the two screw rods is convenient for completing the position adjustment operation of moving up and down and moving left and right by operating one structure, which greatly reduces excessive cumbersome operations. At the same time, the internal threaded tube and the two screw rods are located on the same straight line, which prevents the secondary correction operation of the position between the fill light and the camera.

[0004] Current displacement adjustment devices generally meet the multi-task requirements in 3D vision inspection by adjusting the X, Y and Z axis positions of the camera. However, the contact area between the camera and the fixed structure in existing devices is limited, resulting in poor stability, making the camera susceptible to vibration or external force interference during the adjustment process, affecting the inspection accuracy.

[0006] In order to achieve the above object, the present invention provides the following technical solution: a displacement adjustment device for 3D visual detection, comprising a first slide rail, a first slide seat is slidably mounted on the top of the first slide rail, a second slide rail is fixedly mounted on the top of the first slide seat, a second slide seat is slidably connected to one side of the second slide rail, and a carrying box is installed inside the second slide seat;

[0007] The interior of the carrying box is provided with a receiving cavity, a carrying plate is slidably mounted inside the receiving cavity, a connecting bolt is mounted on the top of the carrying plate, and the connecting bolt is embedded in the interior of the carrying box and is threadedly connected.

[0008] As a further technical solution of the present invention, two accommodating cavities are provided, and the two accommodating cavities are symmetrically distributed.

[0009] As a further technical solution of the present invention, a first rotating shaft is fixedly connected to the top of the carrier box, a motor is installed at the top of the first rotating shaft, and the motor is arranged inside the second slide seat.

[0010] As a further technical solution of the present invention, a protective plate is provided on one side of the two accommodating cavities, and the two protective plates are slidably installed on both sides of the carrying box through a lifting assembly.

[0011] As a further technical solution of the present invention, the lifting assembly includes moving blocks fixedly installed on both sides of the protective plate, threaded rods and limit shafts are respectively installed inside the two moving blocks, a pulley group is installed on the top of the threaded rod, a second rotating shaft is embedded in the inside of the pulley group away from one end of the threaded rod, a second gear is fixedly installed on the top of the second rotating shaft, the outer wall of the second gear is meshedly connected with the first gear, and the first gear is fixedly installed inside the second slide seat.

[0012] As a further technical solution of the present invention, an airbag is arranged inside the protective plate, and an air outlet pipe is evenly installed at the bottom end of the airbag, and the bottom end of the air outlet pipe faces one side of the accommodating cavity.

[0013] As a further technical solution of the present invention, a push plate is provided on one side of the airbag, and sliders are fixedly installed at both ends of the push plate. The two sliders are slidably installed inside the slide groove, and the two slide grooves are opened on the inner wall of the carrier box.

[0014] As a further technical solution of the present invention, the slider is slidably installed inside the protective plate, and a spring is installed between the slider and the protective plate.

[0015] As a further technical solution of the present invention, the top end of the airbag is fixedly connected with an air inlet pipe.

[0016] A method for adjusting a displacement adjustment device for 3D vision detection, comprising the following steps:

[0017] S1: When installing the detection equipment, different detection equipment is placed inside the two accommodating chambers, and the carrying plate is fixedly installed in the carrying box by connecting bolts;

[0018] S2: In case of multi-task detection requirements, the motor is started by controlling the PLC. When the motor is started, the first rotating shaft is driven to rotate. The rotation of the first rotating shaft drives the rotation of the carrier box, so that the carrier box is rotated horizontally by 180 degrees, thereby replacing the detection equipment;

[0019] S3: The rotation of the carrier box drives the second gear to rotate in the annular slide groove and meshes with the first gear to rotate. The rotation of the second gear drives the rotation of the second rotating shaft. When the second rotating shaft rotates, it drives the threaded rod to rotate through the pulley group. The rotation of the threaded rod drives the movement of the moving block. The movement of the moving block drives the movement of the protective plate, so that the two protective plates move alternately and change their positions. The protective plate on the side of the detection device to be used is opened, and the protective plate on the side of the detection device after use is closed for protection.

[0020] S4: When one of the protective plates moves downward, the slider slides in the inner wall of the slide groove. When the slider moves to the raised portion of the slide groove, it is guided to move to one side. The movement of the slider drives the movement of the push plate, which moves to one side of the airbag to squeeze it, so that the gas inside the airbag is discharged from the air outlet pipe and blown to the surface of the lens of the detection equipment;

[0021] S5: When the other protective plate moves upward, after the upward sliding block of the protective plate is separated from the protruding part of the slide groove, the elastic potential energy is released through the slide groove to reset, and air is taken in through the air intake pipe to store air inside the airbag;

[0022] S6: Finally, the second slide moves up and down on one side of the second slide rail, and the first slide moves on the top of the first slide rail to move the detection device to perform detection.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention adopts the setting of a carrying box. When installing the detection device, the detection device is installed in the accommodating cavity. Placing the detection device through the carrying box can not only protect the detection device, but also increase the contact area between the detection device and the traditional fixed structure, which helps to improve the stability of the detection device during displacement adjustment, thereby ensuring the detection accuracy.

[0025] 2. The present invention adopts the setting of rotating the carrier box. When different cameras need to be replaced in case of multi-task detection (such as detecting surface defects with a visible light camera and detecting internal structure with an infrared camera), the motor is started by controlling the PLC. When the motor starts, it drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the rotation of the carrier box, so that the carrier box rotates horizontally 180 degrees, thereby replacing the detection equipment, which helps to improve the detection efficiency.

[0026] 3. The present invention provides a lifting assembly. When the carrying box rotates to replace the detection device, the rotation of the carrying box drives the second gear to rotate in the circular groove and meshes with the first gear to rotate. The rotation of the second gear drives the rotation of the second rotating shaft. When the second rotating shaft rotates, it drives the threaded rod to rotate through the pulley group. The rotation of the threaded rod drives the movement of the moving block. The movement of the moving block drives the movement of the protective plate, so that the two protective plates move alternately and change their positions. The protective plate on the side of the detection device to be used is opened, and the protective plate on the side of the detection device after use is closed, which helps to improve the flexibility of the equipment.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0037] like Figures 1 to 8 As shown, in an embodiment of the present invention, a displacement adjustment device for 3D vision detection includes a first slide rail 1, a first slide seat 2 is slidably mounted on the top of the first slide rail 1, a second slide rail 3 is fixedly mounted on the top of the first slide seat 2, a second slide rail 3 is slidably connected to one side of the second slide rail 3, and a carrying box 5 is installed inside the second slide seat 4;

[0038] An accommodating chamber 6 is provided inside the carrying box 5 , a carrying plate 7 is slidably mounted inside the accommodating chamber 6 , a connecting bolt 8 is mounted on the top of the carrying plate 7 , and the connecting bolt 8 is embedded in the carrying box 5 and threadedly connected.

[0039] Existing: CN219221888U discloses a displacement adjustment mechanism of a visual inspection camera. This patent discloses the first slide rail 1, the first slide seat 2, the second slide rail 3 and the second slide seat 4 proposed in this application document. This technical means will not be described one by one here;

[0040] When installing the detection equipment, the detection equipment is installed in the accommodating cavity 6 and placed through the carrying box 5. This not only protects the detection equipment, but also increases the contact area between the detection equipment and the traditional fixed structure, which helps to improve the stability of the detection equipment during displacement adjustment, thereby ensuring the detection accuracy.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, two accommodating chambers 6 are provided, and the two accommodating chambers 6 are symmetrically distributed.

[0042] Different cameras are placed inside the two accommodating chambers 6 respectively.

[0043] like Figure 4 As shown, a first rotating shaft 9 is fixedly connected to the top of the carrying box 5 , a motor 10 is installed on the top of the first rotating shaft 9 , and the motor 10 is arranged inside the second slide seat 4 .

[0044] In the case of multi-task detection requirements (such as using a visible light camera to detect surface defects and an infrared camera to detect internal structures), when different cameras need to be replaced, the motor 10 is started through the PLC control. When the motor 10 starts, it drives the first rotating shaft 9 to rotate. The rotation of the first rotating shaft 9 drives the rotation of the carrier box 5, so that the carrier box 5 rotates horizontally one hundred and eighty degrees, thereby replacing the detection equipment, which helps to improve the detection efficiency.

[0045] like Figure 1 , Figure 2 and Figure 4 As shown, a protective plate 11 is disposed on one side of each of the two accommodating chambers 6 , and the two protective plates 11 are slidably installed on both sides of the carrying box 5 through a lifting assembly.

[0046] The positions of the two protective plates 11 are staggered. When one of the detection devices is in use, the protective plate 11 on that side is located at the top. When the other detection device is not in use, the protective plate 11 on that side is located at one side to protect it, thereby reducing dust adhesion and reducing the need for manual cleaning.

[0047] like Figure 4 , Figure 6 and Figure 7 As shown, the lifting assembly includes moving blocks 16 fixedly mounted on both sides of the protective plate 11, threaded rods 17 and limit shafts 18 are respectively installed inside the two moving blocks 16, a pulley group 15 is installed at the top of the threaded rod 17, a second rotating shaft 14 is embedded in the inner part of the pulley group 15 away from the end of the threaded rod 17, a second gear 13 is fixedly mounted on the top of the second rotating shaft 14, the outer wall of the second gear 13 is meshedly connected with the first gear 12, and the first gear 12 is fixedly mounted inside the second slide 4.

[0048] The second slide seat 4 is provided with a slide groove 24 for the second gear 13 to slide, and the slide groove 24 is in a circular ring shape;

[0049] The first gear 12 is in an annular shape and is located inside the annular slide groove 24;

[0050] When the carrier box 5 rotates to replace the detection device, the rotation of the carrier box 5 drives the second gear 13 to rotate in the annular slide groove 24, and meshes with the first gear 12 to rotate. The rotation of the second gear 13 drives the rotation of the second rotating shaft 14. When the second rotating shaft 14 rotates, it drives the threaded rod 17 to rotate through the pulley group 15. The rotation of the threaded rod 17 drives the movement of the moving block 16. The movement of the moving block 16 drives the movement of the protective plate 11, so that the two protective plates 11 move alternately and change their positions. The protective plate 11 on the side of the detection device to be used is opened, and the protective plate 11 on the side of the detection device after use is closed, which helps to improve the flexibility of the equipment.

[0051] like Figure 7 and Figure 8 As shown, an air bag 19 is arranged inside the protective plate 11 , and an air outlet pipe 20 is evenly installed at the bottom end of the air bag 19 , and the bottom end of the air outlet pipe 20 faces one side of the accommodating cavity 6 .

[0052] When the protective plate 11 moves downward, the air outlet pipe 20 moves to one side of the accommodating cavity 6 so that the gas inside the airbag 19 is discharged from the air outlet pipe 20 and blown toward the lens surface of the detection equipment. The impact of the airflow helps to remove light pollutants such as dust attached to the lens surface, thereby extending the life of the lens and improving the detection effect.

[0053] The air outlet pipe 20 is distributed in a downward tilt;

[0054] Since dust and particles naturally fall due to gravity, blowing at a downward angle can make it easier for the dust to break away from the lens and fall directly, avoiding being swept back onto the lens surface by the airflow.

[0055] like Figure 7 and Figure 8 As shown, a push plate 21 is provided on one side of the airbag 19 , and sliders 22 are fixedly installed at both ends of the push plate 21 . The two sliders 22 are slidably installed inside the slide grooves 24 , and the two slide grooves 24 are both opened on the inner wall of the carrying box 5 .

[0056] When the protective plate 11 moves downward, the slider 22 slides in the inner wall of the slide groove 24. When the slider 22 moves to the raised portion of the slide groove 24, it is guided to move to one side. The movement of the slider 22 drives the push plate 21 to move to one side of the airbag 19 to squeeze it, which helps to improve the blowing effect.

[0057] like Figures 1 to 8 As shown, the slider 22 is slidably installed inside the protective plate 11, and a spring 23 is installed between the slider 22 and the protective plate 11.

[0058] When the push plate 21 squeezes the airbag 19, the spring 23 deforms to store elastic potential energy;

[0059] When the protective plate 11 moves upward and the slider 22 is separated from the protruding portion of the slide groove 24 , the slide groove 24 releases elastic potential energy to reset the protective plate 11 .

[0060] like Figures 1 to 8 As shown, the top end of the air bag 19 is fixedly connected with an air intake pipe 25 .

[0061] A one-way valve is installed outside the air intake pipe 25 . When the protection plate 11 moves upward, air is taken in through the air intake pipe 25 to store air inside the airbag 19 .

[0062] A method for adjusting a displacement adjustment device for 3D vision detection, comprising the following steps:

[0063] S1: When installing the detection equipment, different detection equipment is placed inside the two accommodating chambers 6, and the carrying plate 7 is fixedly installed in the carrying box 5 by connecting bolts 8;

[0064] S2: In case of multi-task detection requirements, the motor 10 is started by PLC control. When the motor 10 is started, the first rotating shaft 9 is driven to rotate. The rotation of the first rotating shaft 9 drives the rotation of the carrier box 5, so that the carrier box 5 is horizontally rotated 180 degrees, thereby replacing the detection equipment;

[0065] S3: The rotation of the carrier box 5 drives the second gear 13 to rotate in the annular slide groove 24, and meshes with the first gear 12 to rotate. The rotation of the second gear 13 drives the rotation of the second rotating shaft 14. When the second rotating shaft 14 rotates, it drives the threaded rod 17 to rotate through the pulley group 15. The rotation of the threaded rod 17 drives the movement of the moving block 16. The movement of the moving block 16 drives the movement of the protective plate 11, so that the two protective plates 11 move alternately and change their positions. The protective plate 11 on the side of the detection device to be used is opened, and the protective plate 11 on the side of the detection device after use is closed for protection.

[0066] S4: When one of the protection plates 11 moves downward, the slider 22 slides in the inner wall of the slide groove 24. When the slider 22 moves to the raised portion of the slide groove 24, it is guided to move to one side. The movement of the slider 22 drives the push plate 21 to move to one side of the airbag 19 to squeeze it, so that the gas inside the airbag 19 is discharged from the air outlet pipe 20 and blown to the surface of the lens of the detection equipment;

[0067] S5: When the other protective plate 11 moves upward, after the sliding block 22 of the protective plate 11 moves upward and separates from the protruding portion of the slide groove 24, the slide groove 24 releases elastic potential energy to reset, and air is introduced through the air intake pipe 25 to store air inside the airbag 19;

[0068] S6: Finally, the second slide 4 moves up and down on one side of the second slide rail 3 and the first slide 2 moves on the top of the first slide rail 1 to move the detection device to a different position for detection.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
