Description

Technical Field

[0001] The present invention relates to the field of limiting functions, and in particular to a 3D flatness detection device with limiting functions and a use method thereof. Background Art

[0002] 3D flatness detection equipment is usually composed of key parts such as laser generator, imaging system, photosensitive device, data acquisition and processing system. The laser generator is responsible for emitting a highly directional and stable laser beam. The imaging system captures the reflected image formed by the laser on the surface of the object. The photosensitive device converts the light signal into an electrical signal. Finally, the electrical signal is analyzed and calculated through the data acquisition and processing system to construct a three-dimensional model of the object surface and calculate the flatness deviation.

[0003] The limit function plays a vital role in 3D flatness detection equipment. It limits the movement range of the object being measured in the horizontal, vertical or rotational direction to ensure that the object will not be accidentally displaced or tilted during the detection process, thereby ensuring the accuracy and consistency of the measurement results.

[0004] The patent application publication number is CN219347682U, which discloses a 3D flatness detection device. By limiting the rotating shaft through the limiting slide groove, a plurality of rubber clamping blocks can be close to or away from each other along the plurality of limiting slide grooves, thereby achieving the purpose of clamping and fixing the product through a plurality of rubber clamping blocks, further improving the fixing efficiency of the product, and preventing the clamping force from being too large and causing damage to the product through the rubber clamping blocks. After clamping, the product can be 3D flatness detected through an industrial camera.

[0019] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit 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.

[0020] For example, see Figure 1 - Fig.10 The present invention provides a 3D flatness detection device with a limiting function and a method for using the same. The 3D flatness detection device with a limiting function comprises: a 3D flatness detection device body 1 and a placement slot 3. The interior of the 3D flatness detection device body 1 is fixedly connected with a support frame. The outer walls of the two support frames are slidably connected with a mounting plate 2. A fixing column 7 is fixedly connected to the middle position of the top of the mounting plate 2. A track 21 is provided on the outer wall of the top of the mounting plate 2 near the outer wall of the fixing column 7. A support leg 62 is movably contacted inside the track 21. A buffer spring 61 is fixedly connected to the outer wall of the top of the plurality of support legs 62. The outside of the top of a buffer spring 61 is fixedly connected to a moving shell 6, the inside of multiple moving shells 6 is slidingly connected to the outer wall of the support leg 62, the inside of the bottom of multiple support legs 62 is rotatably connected to a universal ball 63, the outer wall of multiple universal balls 63 is rotatably connected to the inside of the track 21, the outer wall of the top of multiple moving shells 6 is fixedly connected to the outer wall of the bottom of the placement slot 3, the inside of the fixed column 7 is movably connected to a cross plate 71, the outer wall of the bottom of the cross plate 71 is fixedly connected to multiple buffer springs 72, the outer wall of the top of the cross plate 71 is fixedly connected to a motor 73, and the input end of the motor 73 is fixedly connected to the middle position of the bottom outer wall of the placement slot 3.

[0021] By moving the support leg 62 inside the track 21, precise limiting and guiding are provided for the rotation of the placement slot 3, ensuring that the placement slot 3 can remain stable during rotation, reducing shaking and deviation, thereby improving the accuracy of detection and further increasing the stability of the movement of the placement slot 3. By setting the universal ball 63, the friction between the support leg 62 and the track 21 can be reduced.

[0022] Embodiment 2, on the basis of embodiment 1, a through hole connected to the outer walls on both sides is opened on the placement groove 3, a plurality of through holes are fixedly connected to the inside of the fixing grooves 5, a plurality of fixing grooves 5 are slidably connected to the inside of the fixing rods 5, a clamping plate 53 is fixedly connected to the outer wall at one end of the fixing rod 51, a rubber block 54 is movably contacted to the outer wall on one side of the clamping plate 53, a reset spring 55 is fixedly connected to the outer wall at one end of the fixing groove 5, and the outer wall at one end of the reset spring 55 is fixedly connected to the outer wall on the other side of the clamping plate 53.

[0023] By controlling the movement of multiple splints 53 through the action of the reset spring 55, each splint 53 can be moved individually, so that each splint 53 can be better contacted and fixed with the product, avoiding that individual splints 53 cannot contact with the product, and accordingly ensuring that each splint 53 can fit tightly and evenly on different parts of the product, thereby increasing the flexibility and adaptability of the splint 53, and even if the product has a slightly irregular shape or a slight difference in size, it can achieve effective and stable fixation, thereby improving the accuracy and reliability of detection.

[0024] Embodiment 3, on the basis of embodiment 2, an airbag 91 is provided inside the splint 53, an outer wall on one side of the airbag 91 is fixedly connected to a push plate 531, an outer wall of the push plate 531 is slidably connected to the inside of the splint 53, an outer wall on the top of the airbag 91 is fixedly connected to an air outlet pipe 9, an outer wall of the air outlet pipe 9 is fixedly connected to the outer wall of the top of the splint 53, and an outer wall on one side of the push plate 531 is fixedly connected to the outer wall on one side of the rubber block 54.

[0025] The airbag 91 is squeezed by the clamping plate 53, and when the airbag 91 is subjected to force, the internal gas is blown onto the product through the outlet pipe 9, so that the dust on the surface of the product can be blown off. While fixing the product, the airflow blown out by the airbag 91 can automatically remove the dust on the surface of the product. No additional manual cleaning steps are required, which improves production efficiency and avoids the use of items such as brushes or cloths, which can easily leave scratches on the product surface. Correspondingly, the use of airflow cleaning completely avoids this risk.

[0026] Embodiment 4, on the basis of embodiment 3, a return spring 1 42 is fixedly connected inside the fixed groove 5, a fixed plate 43 is fixedly connected to the outer wall at the bottom of the return spring 1 42, a square hole is opened inside the fixed plate 43, a limiting plate 44 is slidably connected inside the square hole, a protrusion 1 is fixedly connected to one side inside the square hole, a protrusion 2 is fixedly connected to the outer wall on one side of the limiting plate 44, a return spring 3 45 is fixedly connected to the outer wall on the top of the protrusion 1, the outer wall on the top of the return spring 3 45 is fixedly connected to the outer wall at the bottom of the protrusion 2, the outer wall on the top of the fixing rod 51 is fixedly connected to the limiting block 2 52, one side of the bottom of the limiting plate 44 is an inclined surface, and the outer wall on one side of the limiting block 2 52 is in movably contact with the outer wall on one side of the limiting plate 44.

[0027] By limiting the limit block 2 52 with the limit plate 44, the fixing rod 51 cannot drive the limit block 2 52 to move back, which avoids the situation that when the splint 53 is fixing the product, the product pushes the splint 53 to move due to vibration during the detection process, thereby loosening the fixation of the splint 53 on the output. The stability of the splint 53 is correspondingly enhanced. Stable fixation not only helps to improve the detection accuracy, but also effectively protects the product from damage.

[0028] Embodiment 5, on the basis of embodiment 4, a sliding hole is opened on the outside of the top of the fixing groove 5, a U-shaped rod 41 is slidably connected inside the sliding hole, the outer wall of the top of the plurality of U-shaped rods 41 is fixedly connected to the same circular pull rod 4, the outer wall of the bottom of the U-shaped rod 41 is fixedly connected to a fixing plate 43, the outer wall of the bottom of the fixing plate 43 is fixedly connected to a blocking plate 84, the inside of the fixing groove 5 is rotatably connected to a threaded rod 8, the lower part of the outer wall of the threaded rod 8 is fixedly connected to a gear 81, the fixing plate 43 is opened at the position of the gear 81 with a threaded hole, the inner part of the threaded hole is fixedly connected to the outer wall of the fixing plate 43, and the fixing plate 43 is fixedly connected to the outer wall of the fixing plate 43. The outer wall of the fixing rod 51 is threadedly connected to the outer wall of the gear 81, a slide groove 83 is provided on the outer wall at the top of the fixing rod 51, a cavity is provided on the outer wall on one side of the fixing rod 51, a tooth seat 82 is slidably connected inside the cavity, a push spring 86 is fixedly connected to the outer wall on one side of the tooth seat 82, the outer wall of one end of the push spring 86 is fixedly connected to the inside of the cavity, a baffle plate 85 is fixedly connected to the outer wall on the top of the slide groove 83, the outer wall on one side of the baffle plate 85 is in movably contact with the outer wall on one side of the baffle plate 84, and the outer wall on the other side of the tooth seat 82 is meshingly connected with the outer wall of the gear 81.

[0029] By moving the blocking plate 84 upward, the blocking plate 85 can be released. At this time, under the action of the push spring 86, the tooth holder 82 can be pushed to slide inside the cavity of the fixing rod 51, so that the tooth holder 82 and the gear 81 are meshed and contacted. The automatic transmission mechanism simplifies the operation process and realizes the linkage between the components without manual intervention. By driving the gear 81 to rotate through the threaded rod 8, the gear 81 can drive the tooth seat 82 to move to the outside of the fixing groove 5, and then through the movement of the tooth seat 82, the fixing rod 51 can drive the clamping plate 53 to release the fixation of the product and quickly release the clamped product. The corresponding quick release method improves production efficiency and reduces operation time.

[0030] Embodiment 6, on the basis of embodiment 1, a square groove is opened inside the track 21, a plurality of square grooves are fixedly connected inside with a support rod, the outer wall of the support rod is rotatably connected to a limit block 22, a plurality of square grooves are fixedly connected inside with an elastic protrusion 23, the outer wall of the elastic protrusion 23 is in movable contact with the outer wall of one side of the limit block 22, and the outer wall of the other side of the limit block 22 is in movable contact with the outer wall of the support leg 62.

[0031] This avoids the situation where the placement slot 3 and the movable shell 6 and supporting leg 62 connected thereto stop moving, due to inertia or external factors, these components may rotate back unstably. Accordingly, the design of the limit block 22 effectively prevents this situation from happening. When the supporting leg 62 passes through the limit block 22, the limit block 22 is pushed into the inside of the square slot and then reset under the action of the elastic protrusion 23. This process ensures that the placement slot 3 can stably remain in the predetermined position when it stops, and there will be no unnecessary rebound or shaking, which helps to accurately position the product to the required position and angle during the detection process, thereby improving the accuracy and reliability of the detection.

[0032] In actual use, first, after placing the product to be tested in the middle position inside the placement groove 3, by releasing the fixation between the gear 81 and the tooth seat 82, the clamping plate 53 can be pushed to move under the action of the reset spring 2 55, and then the movement of the clamping plate 53 can drive the fixing rod 51 to slide inside the fixing groove 5, so that the clamping plate 53 drives the rubber block 54 to contact and fix the product. By using the rubber block 54 as the contact surface, the pressure and friction of the clamping plate 53 on the surface of the product can be reduced, avoiding scratches, indentations or other forms of damage during the fixing process. , and accordingly maintains the perfection of the product appearance. By controlling the movement of multiple splints 53 through the action of the reset spring 2 55, each splint 53 can be moved individually, so that each splint 53 is better in contact and fixed with the product, avoiding that individual splints 53 cannot contact with the product, and accordingly ensuring that each splint 53 can fit tightly and evenly on different parts of the product, thereby increasing the flexibility and adaptability of the splint 53, even if the product has a slightly irregular shape or a slight difference in size, it can achieve effective and stable fixation, thereby improving the accuracy and reliability of detection.

[0033] When the fixing rod 51 drives the second limit block 52 to slide inside the fixing groove 5, the second limit block 52 can be pushed by the inclined surface on one side of the limit block 52 and the inclined surface on one side of the limit plate 44 when passing under the limit plate 44, and the limit plate 44 is pushed to slide upward inside the square hole on the fixing plate 43 under the thrust generated by the movement of the second limit block 52, so that the limit plate 44 moves to the top of the second limit block 52, and the fixing rod 51 drives the second limit block 52 to move forward. After the second limit block 52 passes the limit plate 44, the reset spring 45 drives the second limit block 52 to move forward. The plate 44 is reset to its original position and fixed on the other side of the limit block 52. The other side of the limit block 52 and the other side of the limit plate 44 are both vertical surfaces. The limit block 52 is limited by the limit plate 44, and the fixing rod 51 cannot drive the limit block 52 to move back. This avoids the situation where the clamp 53 is fixed to the product due to vibration during the detection process, causing the product to push the clamp 53 to move, thereby loosening the fixation of the clamp 53 on the output. The stability of the clamp 53 is correspondingly enhanced. Stable fixation not only helps to improve the detection accuracy, but also effectively protects the product from damage.

[0034] It should be noted that the elastic force of the second return spring 55 itself is greater than the gravity of the clamping plate 53 and the fixing rod 51 , and is also greater than the friction force between the second limit block 52 and the limit plate 44 .

[0035] When the product is fixed by the clamping plate 53, an extrusion force is generated on the rubber block 54. When the rubber block 54 is subjected to the extrusion force, the rubber block 54 can drive the push plate 531 to move toward the inside of the clamping plate 53, so that the clamping plate 53 squeezes the airbag 91. When the airbag 91 is subjected to force, the internal gas is blown onto the product through the air outlet pipe 9, and the floating dust on the surface of the product can be blown off. While fixing the product, the airflow blown out by the airbag 91 is used to automatically remove the floating dust on the surface of the product. No additional manual cleaning steps are required, thereby improving production efficiency and avoiding the use of items such as brushes or cloths, which are easy to leave scratches on the product surface. The corresponding use of airflow cleaning completely avoids this risk.

[0036] When the splint 53 returns to its original position and releases the fixation on the product, the rubber block 54 can return to its original position on the push plate 531 due to its own elasticity. At this time, the deflated airbag 91 is inflated by the push plate 531, and air can enter the interior of the airbag 91 through the air outlet pipe 9, ensuring that the airbag 91 can blow out sufficient airflow to clean the product surface again when it is used next time. The airbag 91 can be reset and inflated without manual operation, thereby improving work efficiency and automation.

[0037] It should be noted that: when the push plate 531 pulls the airbag 91 to expand, since the internal pressure of the airbag 91 is lower than the external environmental pressure, air will enter the airbag 91 through the air outlet pipe 9, and the air outlet pipe 9 is a two-way channel.

[0038] After the product is fixed by the clamping plate 53, the motor 73 can be started, and then the placement slot 3 can drive the product to rotate through the movement of the motor 73, so that the product can adjust its angle and better adapt to the detection environment.

[0039] The second buffer spring 72 provided at the bottom of the motor 73 can then transfer the vibration generated by the movement of the motor 73 to the second buffer spring 72 through the cross plate 71 for release, thereby preventing the vibration generated by the motor 73 during operation from being transferred to the product and affecting the stability and detection accuracy of the product. Accordingly, the second buffer spring 72 absorbs and releases the vibration energy of the motor 73 during operation, thereby effectively reducing the vibration amplitude of the motor 73.

[0040] While the placement slot 3 is rotating, the movable shell 6 can drive the support leg 62 to rotate inside the track 21. The support leg 62 moves inside the track 21, which provides precise limiting and guiding for the rotation of the placement slot 3, ensuring that the placement slot 3 can remain stable during the rotation process, reducing shaking and deviation, thereby improving the accuracy of detection and further increasing the stability of the movement of the placement slot 3. The friction between the support leg 62 and the track 21 can be reduced by setting the universal ball 63.

[0041] By setting the buffer spring 61, when the product encounters vibration during inspection, the vibration force can be transmitted to the buffer spring 61 through the movable shell 6, and then the elasticity of the buffer spring 61 can effectively convert the vibration energy into the potential energy of the spring, and release the energy through its own deformation, thereby reducing the direct impact and vibration transmission to the product.

[0042] When the support leg 62 rotates inside the track 21, it can push the limit block 22 when passing through the limit block 22, so that the limit block 22 rotates on the support rod into the inside of the square groove. After the support leg 62 passes, the limit block 22 can be pushed to its original position under the action of the elastic protrusion 23, avoiding the placement slot 3 and its connected movable shell 6 and support leg 62 from rotating unstably due to inertia or external factors after the placement slot 3 and its connected movable shell 6 and support leg 62 stop moving. Accordingly, the design of the limit block 22 effectively prevents this situation from occurring. When the support leg 62 passes through the limit block 22, the limit block 22 is pushed into the inside of the square groove and then reset under the action of the elastic protrusion 23. This process ensures that the placement slot 3 can stably remain in the predetermined position when it stops, and there will be no unnecessary rebound or shaking, which helps to accurately position the product to the required position and angle during the detection process, thereby improving the accuracy and reliability of the detection.

[0043] When it is necessary to release the fixation of the clamping plate 53 on the product, the circular pull rod 4 can be pulled, and then through the movement of the circular pull rod 4, multiple U-shaped rods 41 can be driven to move simultaneously, and then the movement of the U-shaped rod 41 can be used to make the fixing plate 43 drive the limiting plate 44 to move upward, and at the same time drive the blocking plate 84 to move upward, so that the threaded hole on the U-shaped rod 41 can drive the threaded rod 8 to rotate inside the fixing groove 5, and through the upward movement of the limiting plate 44, the limiting plate 44 can be made to leave one side of the limiting block 2 52, thereby releasing the fixation of the limiting block 2 52 by the limiting plate 44, making it easier for the fixing rod 51 to drive the clamping plate 53 to return to its original position, and by pulling the circular pull rod 4, multiple U-shaped rods 41 and subsequent components can be driven to move at the same time, thereby realizing the rapid unlocking of the clamping plate 53, thereby simplifying the operation steps and improving work efficiency.

[0044] By driving the movement of the blocking plate 84 through the limit plate 44, the blocking plate 84 can slide upward from the inclined surface of the blocked plate 85, and then the blocked plate 85 and one end of the inclined surface of the blocking plate 84 are extended planes, so that when the fixing plate 43 drives the blocking plate 84 to move upward until it stops, the blocking plate 84 can always be in contact with the blocked plate 85. This contact not only helps to maintain the stability of the structure, but also provides a reliable basis for the subsequent operation of the blocking plate 84 to push the blocked plate 85 to return to its original position again.

[0045] By moving the blocking plate 84 upward, the blocking plate 85 can be released. At this time, under the action of the pushing spring 86, the tooth seat 82 can be pushed to slide inside the cavity of the fixing rod 51, so that the tooth seat 82 and the gear 81 are meshed and contacted. The operation process is simplified by the automatic transmission mechanism, and the linkage between the components can be achieved without human intervention.

[0046] It should be noted that, by providing the sliding groove 83 , the reciprocating motion of the fixing rod 51 in the fixing groove 5 will not be affected by the baffle 85 being fixed on the gear seat 82 .

[0047] At this time, the threaded rod 8 drives the gear 81 to rotate, so that the gear 81 can drive the tooth seat 82 to move to the outside of the fixing groove 5, and then through the movement of the tooth seat 82, the fixing rod 51 can drive the clamping plate 53 to release the fixation of the product and quickly release the clamped product. The corresponding quick release method improves production efficiency and reduces operation time.

[0048] 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.
