Description

Technical Field

[0001] This utility model relates to the field of precision measurement technology, and in particular to an automatic sorting device for high-precision part size measurement. Background Technology

[0002] Automatic sorting devices are equipment that integrate dimensional detection, feature recognition, and automated sorting functions. They can accurately acquire the dimensional data of parts through sensors and then automatically classify qualified products, unqualified products, or products of different specifications according to preset standards. High-precision parts have extremely small dimensional tolerances. Manual measurement and sorting are prone to errors due to fatigue and operational differences, and are also inefficient. Automatic sorting devices can achieve high-speed, repeatable measurement and sorting with micron-level accuracy, ensuring consistent results and meeting the stringent requirements for quality control and production efficiency in precision manufacturing.

[0003] A search revealed Chinese patent publication number CN214812827U, which discloses a sorting device comprising a scanning mechanism, a transmission mechanism, an execution mechanism, and a sorting mechanism. The scanning mechanism is used to scan the QR code of the express delivery. The transmission mechanism is used to transport the sorted goods via a conveyor belt and, based on the required conveying speed, uses a two-stage reducer to reduce the speed of the motor to achieve the desired conveying speed. The execution mechanism uses a crank-slider mechanism to push the transported goods to the sorting port. The sorting mechanism uses a motor to drive a short threaded rod connected to a robotic arm to open and close the robotic arm, and drives a long threaded rod connected to the robotic arm to move the robotic arm, ultimately achieving the movement and sorting of goods at the sorting port.

[0004] The aforementioned patent mentions the beneficial effects: "The use of a semi-automatic method combining machine and manual labor reduces manual sorting costs. Compared with fully automated machines, it has advantages such as simple structure, low cost, and convenient maintenance." Although the above solution can solve the problem, in the prior art, the sensors of some devices are mostly rigidly fixed, such as being fastened to specific brackets or measuring modules with bolts. This design makes it cumbersome and time-consuming to adjust the position of the sensors. Not only is it difficult to quickly adapt to the measurement needs of different specifications of parts, but frequent disassembly and assembly may also introduce mechanical errors, reduce measurement accuracy, and restrict the device's flexible response capability to multi-variety, small-batch production scenarios. Therefore, an automatic sorting device for high-precision part size measurement is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1 to 3 This utility model provides an embodiment of an automatic sorting device for high-precision component size measurement, including a guide rail 1. The guide rail 1 is the basic guiding component of the device, used to provide a track for the installation and sliding of the adjustment mechanism 2, and to support the overall adjustment structure. The adjustment mechanism 2 is installed inside the guide rail 1. The adjustment mechanism 2 is installed inside the guide rail 1 and can slide along the inner wall of the guide rail 1 to realize the position adjustment function of the sensor 25. The outer walls of the two guide rails 1 are fixedly connected to the support frame 3. The support frame 3 is fixedly connected to the outer walls of the two guide rails 1, and plays the role of connecting and supporting the guide rails 1, thereby enhancing the stability of the overall structure of the device.

[0026] A control box 4 is fixedly connected to the outer wall of the support frame 3. The control box 4 is fixed to the outer wall of the support frame 3 and serves as the mounting carrier for components such as the swing mechanism 5. At the same time, it protects the internal structure from external interference. The swing mechanism 5 is installed inside the control box 4. The swing mechanism 5 is installed inside the control box 4 and is used to drive the screening rod 52 to complete the sorting action of the parts. A protective shell 6 is fixedly connected to the top of the control box 4. The protective shell 6 is fixed to the top of the control box 4 and is used to protect some components of the swing mechanism 5 and prevent dust, debris and other objects from entering and affecting its operation.

[0027] The adjustment mechanism 2 includes a sliding column 21, which is the core transmission component of the adjustment mechanism 2. It is used to transmit operating force and drive other components to move. The outer wall of the sliding column 21 is slidably connected to the inner wall of the guide rail 1. The sliding column 21 can slide up and down along the inner wall of the guide rail 1, providing a moving basis for the position adjustment of the sensor 25. A button 22 is fixedly connected to the top of the sliding column 21. The button 22 is fixed to the top of the sliding column 21, which allows the operator to control the movement of the sliding column 21 by pressing and rotating. A support ring 23 is fixedly connected to the outer wall of the sliding column 21. The support ring 23 is fixed to the outer wall of the sliding column 21 and is used to bear the force of the spring 281, so that the spring 281 can be compressed or extended as the sliding column 21 moves. A limit block 24 is fixedly connected to the bottom of the sliding column 21. The limit block 24 is fixed to the bottom of the sliding column 21 and locks and unlocks the sensor 25 and the gear 26 by inserting or disengaging from the corresponding groove.

[0028] A sensor 25 is slidably connected to the inner wall of the guide rail 1. The sensor 25 can slide along the inner wall of the guide rail 1, and its position can be adjusted to meet the size measurement needs of different specifications of parts. A gear 26 is rotatably connected to the bottom end of the sensor 25. The gear 26 is rotatably connected to the bottom end of the sensor 25 and can drive the sensor 25 to move along the rack 27 to adjust the horizontal position of the sensor 25. The rack 27 is fixedly connected to the inner wall of the guide rail 1. The rack 27 is fixed to the inner wall of the guide rail 1 and meshes with the gear 26 to provide a moving track for the gear 26 and ensure the accuracy of the movement of the sensor 25. A reset component 28 is provided on the outside of the sliding column 21. The reset component 28 is located outside the sliding column 21 and is used to automatically reset the sliding column 21 and the limit block 24 after the operation is completed, so as to lock the position of the sensor 25.

[0029] Reference Figure 2 and Figure 3 The reset assembly 28 includes a spring 281, which is an elastic component of the reset assembly 28, providing elastic force for the reset of the sliding column 21. The outer wall of the spring 281 is sleeved on the outside of the sliding column 21, and the two ends of the spring 281 are respectively connected to the support ring 23 and the sensor 25. It can be compressed or extended as the sliding column 21 moves. The inner wall of the gear 26 has a groove 282, which is adapted to the limiting block 24. When the limiting block 24 is inserted, it can restrict the rotation of the gear 26. The inner wall of the sensor 25 has a groove 283, which cooperates with the limiting block 24. When the limiting block 24 is inserted, it can fix the position of the sensor 25.

[0030] Reference Figure 2 and Figure 4The swing mechanism 5 includes a motor 51, which is the power source of the swing mechanism 5 and provides driving force for the swing of the screening rod 52. The outer wall of the motor 51 is fixedly connected to the inner wall of the control box 4. The motor 51 is fixed to the inner wall of the control box 4 to ensure its stability during operation and avoid vibration affecting the sorting accuracy. The drive end of the motor 51 is fixedly connected to the screening rod 52, which is connected to the drive end of the motor 51. The motor drives the swing to push the parts to complete the sorting. The inner wall of the protective shell 6 is detachably connected to an elastic column 53. The elastic column 53 is detachably installed on the inner wall of the protective shell 6 for easy replacement. At the same time, the elastic column 53 is fixedly connected to the top of the elastic column 53 by the pressing pressure of the elastic buffer button 54. The button 54 is fixed to the top of the elastic column 53 and is used to trigger the movement of the limit plate 55 to realize the disassembly and assembly operation of the screening rod 52. The outer wall of the button 54 is fixedly connected to two limit plates 55.

[0031] Two limiting plates 55 are fixed to the outer wall of button 54, and together with fixing block 574, they limit and fix the screening rod 52. A pushing block 56 is detachably connected to the bottom end of the limiting plate 55. The pushing block 56 is detachably connected to the bottom end of the limiting plate 55 and is used to transmit the downward force of the limiting plate 55 to the inclined block 575, triggering the support mechanism 57 to unlock. A support mechanism 57 is provided on the inner wall of the protective shell 6. The support mechanism 57 provides locking support for the limiting plate 55, ensuring the stable installation of the screening rod 52. The support mechanism 57 includes a support plate 571, which is the basic component of the support mechanism 57 and is used to install the damper 572 and the spring 576. The outer walls of the two support plates 571 are fixedly connected to the inner wall of the protective shell 6, providing a stable installation base for the support mechanism 57. The damper 572 is fixedly connected to the opposite side of the support plate 571. The damper 572 is fixed to the opposite side of the support plate 571 and is used to slow down the movement speed of the sliding plate 573 to ensure the smooth operation of the support mechanism 57.

[0032] A sliding plate 573 is fixedly connected to the outer wall of the damper 572. The sliding plate 573 is connected to the outer wall of the damper 572 and can move with the extension and retraction of the damper 572, driving the fixed block 574 and the inclined block 575 to move. The fixed block 574 is fixedly connected to the outer wall of the sliding plate 573 and is fixed to the outer wall of the sliding plate 573. It can be locked by engaging with the notch of the limiting plate 55 or unlocked by disengaging from the notch. The inclined block 575 is fixedly connected to the outer wall of the sliding plate 573 and can convert the vertical force of the pushing block 56 into the horizontal force of the sliding plate 573, realizing the change of force direction. A second spring 576 is sleeved on the outside of the damper 572. The second spring 576 is sleeved on the outside of the damper 572 and its two ends are connected to the support plate 571 and the sliding plate 573, providing elastic force to reset the sliding plate 573 and realize the locking of the fixed block 574.

[0033] Reference Figures 3 to 5 The outer walls of the two push blocks 56 are slidably connected to the inner wall of the protective shell 6. The two push blocks 56 can slide up and down along the inner wall of the protective shell 6 to ensure that they can stably transmit the force to the inclined block 575 when subjected to force. The outer walls of the two inclined blocks 575 are slidably connected to the outer walls of the push blocks 56. The two inclined blocks 575 slide in contact with the push blocks 56, so that the downward movement of the push blocks 56 can be converted into the horizontal movement of the inclined blocks 575, which drives the sliding plate 573 to move. The outer walls of the two fixed blocks 574 are slidably connected to the outer wall of the limiting plate 55. The two fixed blocks 574 can slide along the outer wall of the limiting plate 55. When the limiting plate 55 moves down, they are pushed open, aligned with the notch, and then locked in place.

[0034] The outer wall of the screening rod 52 is rotatably connected to the inner wall of the protective shell 6. The screening rod 52 can rotate within the protective shell 6, ensuring that it can swing flexibly to complete the sorting under the drive of the motor 51. One end of the spring 281 is fixedly connected to the bottom end of the support ring 23, and the other end of the spring 281 is fixedly connected to the top end of the sensor 25. The two ends of the spring 281 are respectively connected to the support ring 23 and the sensor 25. When the support ring 23 moves down, the spring is compressed. When it is released, it drives the sliding column 21 to reset. One end of each of the two springs 576 is fixedly connected to the outer wall of the support plate 571, and the other end of each spring 576 is fixedly connected to the outer wall of the sliding plate 573. The two ends of the two springs 576 are connected to the support plate 571 and the sliding plate 573. When the sliding plate 573 moves, the spring is stretched. When it is released, it pulls the sliding plate 573 to reset, driving the fixing block 574 to lock the limit plate 55.

[0035] The outer wall of the sliding column 21 contacts the inner wall of the sensor 25, ensuring that the sliding column 21 can stably drive the limiting block 24 to act on the sensor 25 when it moves, thus locking or unlocking. The outer side of the gear 26 is meshed with the outer side of the rack 27, allowing the gear 26 to move along the rack 27 when it rotates, thus precisely adjusting the position of the sensor 25. The inner wall of the gear 26 contacts the outer wall of the sliding column 21, ensuring that the limiting block 24 can be embedded in the sliding groove 282 of the gear 26, thus limiting the rotation of the gear 26. A second motor 7 is fixedly connected to the outer wall of the control box 4, providing power to the conveyor belt 8 and driving it to operate. The drive end of the second motor 7 is fixedly connected to the conveyor belt 8. The conveyor belt 8 is connected to the drive end of the second motor 7 and is driven by the motor to transport the parts sequentially to the measurement and sorting areas, ensuring continuous process flow.

[0036] Working principle: When the position of sensor 25 needs to be adjusted, press button 22 down. Button 22 causes sliding column 21 to slide down along the inner wall of guide rail 1. Simultaneously, sliding column 21 causes the support ring 23 fixed on the outer wall to move down. The support ring 23 presses down on the spring 281 sleeved on the outside of sliding column 21, compressing spring 281 and storing elastic force. At the same time, the limiting block 24 at the bottom of sliding column 21 moves down, first sliding away from the inner wall of sensor 25, and then disengaging from the inner wall of gear 26, releasing the restriction on both. Then, rotate button 22 90 degrees. Button 22 causes sliding column 21 to rotate synchronously, and sliding column 21 causes limiting block 24 to rotate together. At this time, limiting block 24 completely releases the rotation restriction on gear 26. When button 22 is pushed, gear 26 meshes with rack 27 fixed to the inner wall of guide rail 1, and rotates along the teeth of rack 27, thereby driving sensor 25 to move smoothly horizontally along guide rail 1, thus adjusting the measurement position of sensor 25.

[0037] When it is necessary to lock the position of sensor 25, rotate button 22 90 degrees in the opposite direction. Button 22 drives sliding column 21 to rotate synchronously. Sliding column 21 then drives limit block 24 to rotate until it aligns with the groove 282 on the inner wall of gear 26. At this time, release the force on button 22. The compressed spring 281 releases its elasticity and pushes support ring 23 upward. Support ring 23 drives sliding column 21 to move upward. Sliding column 21 then drives limit block 24 to slide into groove 282 on gear 26 first, and then into groove 283 on the inner wall of sensor 25. Button 22 then resets, finally achieving stable locking of sensor 25.

[0038] When the screening rod 52 needs to be disassembled, first press button 2 54. Button 2 54 presses down on the elastic column 53 at the bottom. The elastic column 53 absorbs part of the impact force through its own elasticity, playing a buffering and protective role. At the same time, button 2 54 drives the two limiting plates 55 fixed on the outer wall to move downward. After the bottom end of the limiting plate 55 contacts the pushing block 56, it continues to press down on the pushing block 56. After the pushing block 56 is subjected to force, it presses the inclined block 575 on the outer wall of the sliding plate 573. The inclined block 575 slides along the outer wall of the pushing block 56, converting the vertical force into a horizontal force, causing the two sliding plates 573 to move away from each other. When the sliding plate 573 moves, it simultaneously pulls the spring 2 576 connected between the support plate 571 and the sliding plate 573, causing the spring 2 576 to be stretched. At the same time, the fixing block 574 on the outer wall of the sliding plate 573 moves away together. When the fixing block 574 completely leaves the outer wall of the limiting plate 55, the limitation on the limiting plate 55 is released. Because a damper 572 is connected between the sliding plate 573 and the support plate 571, the damper 572 slows down the recovery speed of the sliding plate 573, allowing time for operation. At this time, quickly pull up the second button 54. The second button 54 drives the two limit plates 55 to move upward synchronously, which releases the limit plates 55 from the screen rod 52, and the screen rod 52 can be easily removed and replaced. After being pulled out, the stretched spring 576 releases its tension, pulls the sliding plate 573 to reset, and drives the inclined block 575 and the fixed block 574 back to their initial positions.

[0039] When the screening rod 52 needs to be fixed after installation, the limiting plate 55 is inserted into the mounting position of the protective shell 6. After the outer wall of the limiting plate 55 contacts the fixing block 574 on the sliding plate 573, it continues to move downward, which will push the two fixing blocks 574 to move away from each other. The fixing blocks 574 drive the sliding plate 573 to move away synchronously, and the sliding plate 573 pulls the second spring 576 to be stretched. When the limiting plate 55 moves down to a specific position and the fixing block 574 is aligned with the notch of the limiting plate 55, the stretched spring 576 releases its tension and pulls the two sliding plates 573 to move closer to each other. The sliding plate 573 drives the fixing block 574 to be inserted into the notch of the limiting plate 55, thus locking the limiting plate 55 and achieving a stable fixation of the screening rod 52.
