Description

Technical Field

[0001] This invention relates to the field of automatic weighing technology, and in particular to a vision-guided area automatic weighing device. Background Technology

[0002] In the manufacturing and maintenance of aircraft components, automated weighing and sorting of parts is a crucial step in ensuring assembly accuracy and flight safety. In actual production, it has been found that a special type of component, represented by long, narrow metal frames for aircraft, exhibits a phenomenon of "same mass, different center of gravity distribution." Two components may have identical masses, but one's center of gravity is located at the geometric center, while the other's is significantly off-center. This difference in center of gravity distribution directly affects the balance and installation attitude during subsequent assembly. Therefore, the weighing process must not only distinguish mass but also further differentiate the center of gravity position. Traditional weighing and sorting devices have the following shortcomings: The system is limited to sorting by quality and cannot identify differences in center of gravity, resulting in mixed flow of parts that are of the same quality but not of the same center of gravity, which affects subsequent processes. It also lacks posture detection and has high requirements for the placement of parts on the weighing platform. It cannot automatically calibrate and center, and is prone to introducing weighing errors due to placement deviations.

[0003] To address this, we designed a vision-guided automatic weighing device for specific areas. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of "same mass, different center of gravity distribution" in the prior art. Two parts have the same mass, but one has its center of gravity located in the geometric center area, while the other has its center of gravity significantly deviated from the center area. This difference in center of gravity distribution directly affects the balance and installation posture in the subsequent assembly process. Therefore, a vision-guided automatic regional weighing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vision-guided automatic weighing device for a region includes a weighing frame body and a braking system mounted on the weighing frame body. A slide rail is mounted on the weighing frame body, an electric slider slides on the slide rail, a horizontally placed support frame body is mounted above the electric slider, and an electronic scale connected to the support frame body is mounted on the electric slider. The aircraft parts to be screened and weighed are placed on the rack body, and the rack body is equipped with a parts screening component to screen the center of gravity of the aircraft parts. The slide rail frame has symmetrical screening base bodies mounted on the weighing frame body on both sides. The weighing frame body is equipped with a propulsion mechanism that pushes aircraft parts into the screening base bodies.

[0006] Preferably, there are multiple screening base bodies, and a flipping frame is flipped on the screening base body. The flipping frame flips on the top of the screening base body by an electrically driven flipping shaft. The screening base body is provided with a sliding track for exporting aircraft parts.

[0007] Preferably, the tilting frame includes a first tilting plate and a second tilting plate, an electrically driven tilting shaft is installed at the bottom of the first tilting plate and the second tilting plate, and the first tilting plate and the second tilting plate tilt symmetrically on the slide rail frame.

[0008] Preferably, the support frame body is provided with a counter-pushing mechanism for aligning and calibrating aircraft parts. The counter-pushing mechanism includes electrically driven clamping components. Two electrically driven clamping components are provided and symmetrically arranged on both sides of the top of the support frame body. Sliding holes are provided at both ends of the support frame body, and the electrically driven clamping components slide in opposite directions through the sliding holes.

[0009] Preferably, the accessory screening assembly includes: Lifting plates are provided in multiple configurations. A support plate is provided below the support frame body, and multiple lifting plates arranged in a linear fashion are fixed to the top of the support plate. The sockets are arranged linearly on the support frame body and located in the middle of the support frame body. The lifting plate corresponds to each socket and slides up and down within the socket.

[0010] Preferably, a U-shaped frame is fixed at the bottom of the support frame body, and a connecting pipe is provided between the U-shaped frame and the electric slider. The electronic scale is installed on the electric slider, and the weighing end of the electronic scale is connected to one end of the connecting pipe, while the other end of the connecting pipe is connected to the U-shaped frame.

[0011] Preferably, the tray slides up and down between the U-shaped frame and the tray body, and a rod is fixed on the tray that passes through the U-shaped frame. The rod slides coaxially in the connecting pipe and passes through the electric slider and abuts against the slide rail.

[0012] Preferably, a raised ramp is provided between the two screening base bodies located on both sides of the slide rail frame, and the raised ramp is fixed on the slide rail frame, with the upper surface of the raised ramp being arc-shaped.

[0013] Preferably, the electric slider is U-shaped and has an internal cavity. The width of the internal cavity is the same as the width of the convex block. The bottom of the insertion rod has a rounded corner and passes through the internal cavity, abutting against the top of the slide rail frame and the convex block.

[0014] Preferably, the weighing frame body is also equipped with a vision analysis and control system, and the braking system and vision analysis and control system drive the electric slider to slide on the slide rail frame.

[0015] The beneficial effects of this invention are as follows: 1. This invention, based on traditional electronic scales, automatically lifts aircraft parts at specific locations using a parts screening component. Utilizing the relative positional relationship between the center of gravity and the lifting area, parts with a centered center of gravity remain horizontally balanced, while parts with a deviated center of gravity naturally tilt upwards. A visual analysis and control system monitors the parts' attitude in real time and pushes them into either the first or second tilting tray based on their attitude differences. This achieves automated differentiation of parts with different center of gravity types of the same mass, solving the problem of traditional weighing devices that "only recognize weight, not center of gravity."

[0016] 2. In this invention, multiple sets of screening base bodies are symmetrically arranged on both sides of the slide rail frame. Each set includes a first rotating disk and a second rotating disk, which correspond to two types: center of gravity and center of gravity offset, respectively. By using an electric slider to transfer the parts to the screening bases of different sets, a multi-level sorting logic of segmenting by quality and diverting by center of gravity can be realized, thereby achieving high sorting efficiency and no interference between them, and making it easy to flexibly expand the number of channels according to the needs of the production line.

[0019] Reference Figures 1-7 An automated weighing device based on vision guidance includes a weighing frame body 1 and a braking system mounted on the weighing frame body 1. A slide rail 2 is mounted on the weighing frame body 1, and an electric slider 3 slides on the slide rail 2. The slide rail 2 extends horizontally. The electric slider 3 is driven by the braking system and can move precisely back and forth along the slide rail 2. A vision analysis and control system is also installed on the weighing frame body 1. The braking system and the vision analysis and control system drive the electric slider 3 to slide on the slide rail 2. Therefore, under the action of the braking system and the vision analysis and control system, the electric slider 3 slides on the slide rail 2.

[0020] A horizontally placed support frame body 9 is provided above the electric slider 3, and an electronic scale connected to the support frame body 9 is provided on the electric slider 3. An electronic scale is installed inside or on the side of the electric slider 3, and the weighing end of the electronic scale is connected to the support frame body 9. The aircraft parts 10 to be screened and weighed are placed on the support frame body 9 for real-time detection of the mass of the aircraft parts 10 placed on the support frame body 9. At this time, the mass of the aircraft parts 10 placed on the support frame body 9 will be weighed and marked by the electronic scale placed on the electric slider 3.

[0021] In this embodiment, the aircraft accessory 10 is a long strip metal frame structure, which may have two types: one with the center of gravity in the center and the other with the center of gravity offset. The support frame body 9 is provided with an accessory screening component for screening the center of gravity of the aircraft accessory 10.

[0022] The aircraft parts 10 to be screened and weighed are placed on the rack body 9. The aircraft parts 10 are long metal frames. There are two types of aircraft parts 10 with long metal frames: one type has its center of gravity located in the middle area of ​​the aircraft parts 10, and the other type has its center of gravity deviating from the middle area of ​​the aircraft parts 10. Both types of aircraft parts 10 have the same mass. Traditional automatic weighing devices can only weigh and distribute aircraft parts 10 with the same mass. This device can further subdivide and automatically weigh the parts with their center of gravity located in the middle area of ​​the aircraft parts 10 and the parts with their center of gravity deviating from the middle area of ​​the aircraft parts 10.

[0023] The slide rail frame 2 is symmetrically arranged with screening base body 5 installed on the weighing frame body 1. There are multiple screening base bodies 5, and a flipping frame 6 is flipped on the screening base body 5. There are multiple sets of screening base bodies 5, two in each set and located on both sides of the slide rail frame 2. Each set constitutes a "homogeneous screening assembly" for receiving and exporting accessories of a specific mass or a specific center of gravity type.

[0024] Therefore, based on the weighing, aircraft parts 10 of different masses are transported to two screening base bodies 5 that are arranged opposite each other. The two screening base bodies 5 arranged opposite each other are a homogeneous screening component, so it is possible to distinguish aircraft parts 10 of different masses and transport them to different homogeneous screening components. This makes it convenient to weigh and screen aircraft parts 10 of the same mass again in the future.

[0025] The tilting frame 6 is tilted on top of the screening base body 5 by an electrically driven tilting shaft 8. The tilting frame 6 includes a first tilting disk 61 and a second tilting disk 62. The electrically driven tilting shaft 8 is installed at the bottom of the first tilting disk 61 and the second tilting disk 62, and the first tilting disk 61 and the second tilting disk 62 are tilted symmetrically on the slide rail frame 2. The tilting frame 6 achieves a tilting action of 90° to 180° on top of the screening base body 5 by an electrically driven tilting shaft 8.

[0026] Reference Figure 3 As shown, the electrically driven tilting shaft 8 is installed at the bottom of the first tilting plate 61 and the second tilting plate 62, i.e. on the side away from the slide rail frame 2. The first tilting plate 61 and the second tilting plate 62 can be symmetrically tilted in a direction perpendicular to the slide rail frame 2 under the drive of the electrically driven tilting shaft 8. Through this symmetrical tilting structure, independent or synchronous control of the left and right screening base bodies 5 can be achieved, thereby adapting to the material dropping guidance of aircraft parts 10 with different center of gravity types.

[0027] The screening base body 5 is provided with a glide track 7 for exporting aircraft parts 10. The glide track 7 is arranged at an angle and its end can receive a container or conveyor belt.

[0028] The support frame body 9 is equipped with a counter-pushing mechanism for aligning and calibrating the aircraft parts 10. After the aircraft parts 10 are placed on the support frame body 9, the electronic scale weighs the aircraft parts 10, and the vision analysis and control system distributes the corresponding aircraft parts 10 to the corresponding homogeneous screening components. Therefore, it is only necessary to activate the braking system to drive the electric slider 3 to move to the corresponding position, that is, slide it to the position between the corresponding oppositely set first flip disk 61 and second flip disk 62.

[0029] Reference Figure 4As shown, the opposing pushing mechanism includes two electrically driven clamping members 11, which are symmetrically arranged on the top sides of the support frame body 9. Sliding holes 12 are provided at both ends of the support frame body 9, and the electrically driven clamping members 11 slide opposite each other through the sliding holes 12. When the electrically driven clamping members 11 are activated, the two electrically driven clamping members 11 slide relative to each other and clamp the two ends of the aircraft accessory 10 placed on the support frame body 9. Therefore, the aircraft accessory 10 clamped by the two electrically driven clamping members 11 will be located in the middle position on the support frame body 9. Then the electrically driven clamping members 11 are returned to their original positions, releasing the clamping effect of the electrically driven clamping members 11 on the aircraft accessory 10.

[0030] Therefore, during operation, the two electrically driven clamping parts 11 move towards the center simultaneously, pushing the two ends of the aircraft accessory 10 so that it is precisely located in the center of the support frame body 9, thereby ensuring the force symmetry and detection consistency during subsequent center of gravity detection. After centering is completed, the electrically driven clamping parts 11 are reset and the clamping is released.

[0031] Under the action of the braking system, the electric slider 3, carrying the aircraft accessory 10 on the support frame body 9, moves to the corresponding homogeneous screening component position, as shown in the reference. Figure 4 In this state, during the movement of the electric slider 3, the insert rod 15, which slides coaxially within the connecting tube 14, slides against the top of the slide rail 2. At this time, the top of the support plate on the top of the insert rod 15 and the tops of the multiple lifting plates 16 are located within the insertion hole 17, and the lifting plates 16 do not protrude from the support frame body 9. Therefore, the lifting plates 16 will not push up the aircraft accessory 10 located on the support frame body 9. Reference Figure 4 and Figure 5 As shown, the support frame body 9 is provided with a component screening assembly for screening the center of gravity of aircraft components 10. The component screening assembly includes lifting plates 16. Multiple lifting plates 16 are provided, at least three or more, arranged in a linear manner. A tray is provided below the support frame body 9, and the multiple lifting plates 16 arranged in a linear manner are fixed to the top of the tray.

[0032] Multiple sockets 17 are arranged linearly on the support frame body 9 and located in the middle of the support frame body 9. The lifting plate 16 corresponds to each socket 17. The lifting plate 16 slides up and down within the socket 17. In the initial state, the top of the lifting plate 16 is lower than or flush with the upper surface of the support frame body 9 and does not contact the aircraft accessory 10. At a specific position, such as when passing the ramp 4, the lifting plate 16 rises and passes through the socket 17, lifting the aircraft accessory 10, thereby realizing the attitude detection triggered by the center of gravity, i.e., balance or tilt.

[0033] During the movement of the electric slider 3, the insertion rod 15 slides onto the ramp block 4 on the slide rail 2, and then pushes the insertion rod 15 up inside the connecting pipe 14. Therefore, the two types of accessories with their center of gravity located in the middle area of ​​the aircraft accessory 10 and accessories with their center of gravity deviating from the middle area of ​​the aircraft accessory 10 are automatically weighed and distributed.

[0034] The bottom of the support frame body 9 is fixed with a U-shaped frame 13. A connecting pipe 14 is provided between the U-shaped frame 13 and the electric slider 3. An electronic scale is installed on the electric slider 3, and the weighing end of the electronic scale is connected to one end of the connecting pipe 14. The other end of the connecting pipe 14 is connected to the U-shaped frame 13. Through this connection method, the overall mass of the aircraft accessory 10 and its support frame body 9 is transferred to the electronic scale through the U-shaped frame 13 and the connecting pipe 14 to achieve accurate weighing. At the same time, it ensures that the lifting freedom of the support frame body 9 is not affected by the weighing structure.

[0035] The tray slides up and down between the U-shaped frame 13 and the tray body 9. A rod 15 is fixed on the tray, penetrating the U-shaped frame 13. The rod 15 slides coaxially inside the connecting tube 14 and passes through the electric slider 3, abutting against the slide rail 2. The tray can slide up and down in the gap between the U-shaped frame 13 and the tray body 9. The rod 15 is fixed on the tray, penetrating the U-shaped frame 13. The rod 15 is coaxially slidably disposed inside the connecting tube 14 and extends downward, penetrating the entire structure of the electric slider 3. Its bottom end abuts against the upper surface of the slide rail 2. When the electric slider 3 slides along the slide rail 2, the rod 15 rolls or slides relative to the slide rail 2.

[0036] A raised ramp 4 is provided between the two screening base bodies 5 located on both sides of the slide rail frame 2, and the raised ramp 4 is fixed on the slide rail frame 2. The upper surface of the raised ramp 4 is arc-shaped, with an arc-shaped raised structure, high in the middle and low at both ends. When the electric slider 3 drives the insertion rod 15 to move to the position of the raised ramp 4, the insertion rod 15 is gradually pushed up by the raised ramp 4, thereby pushing the pallet and lifting plate 16 to rise.

[0037] The electric slider 3 is U-shaped and has an internal cavity 18. The width of the internal cavity 18 is the same as the width of the convex block 4. The bottom of the insertion rod 15 has a rounded corner and passes through the internal cavity 18 and abuts against the top of the slide rail frame 2 and the convex block 4 to reduce friction between the slide rail frame 2 and the convex block 4. The insertion rod 15 passes through the internal cavity 18 and its bottom always keeps in contact with the top of the slide rail frame 2 or the convex block 4.

[0038] The weighing frame body 1 is equipped with a propulsion mechanism that pushes the aircraft part 10 into the screening base body 5. This mechanism can be an electric push rod or a pneumatic push rod. It is used to push the aircraft part 10, after the center of gravity detection is completed, from the support frame body 9 into the flipping frame 6 on the corresponding screening base body 5. This will result in the following two states when the lifting plate 16 lifts the protruding insertion hole 17 and acts on the aircraft part 10: One reference Figure 5 In this state, the component with its center of gravity located in the middle area of ​​the aircraft component 10 is lifted by multiple lifting plates 16. The lifted area is located on the same vertical plane as the center of gravity of the aircraft component 10. At this time, the aircraft component 10 will be in a balanced state, that is, still in a horizontal state. The visual analysis and control system detects the horizontal state of the aircraft component 10 and pushes it onto the first flipping disk 61 under the action of the propulsion mechanism. Then, the screening base body 5 is opened and the first flipping disk 61 on the electric drive flipping shaft 8 is driven to flip, flipping the component with its center of gravity located in the middle area of ​​the aircraft component 10 and sliding it away along the sliding track 7. Second reference Figure 6 and Figure 7 In this state, the component whose center of gravity is off the middle area of ​​the aircraft component 10 is lifted by multiple lifting plates 16. The lifted area is not located on the same vertical plane as the center of gravity of the aircraft component 10, but is misaligned. Therefore, the component whose center of gravity is off the middle area of ​​the aircraft component 10 will be in a tilted state. The visual analysis and control system detects the tilted state of the aircraft component 10 and pushes it onto the second flipping plate 62 under the action of the propulsion mechanism. Then, the component whose center of gravity is off the middle area of ​​the aircraft component 10 is flipped over and slides away along the sliding track 7.

[0039] The weighing frame body 1 is also equipped with a vision analysis and control system, including an industrial camera, an image processor and a PLC controller. The braking system and the vision analysis and control system jointly control the sliding position of the electric slider 3 on the slide rail 2, and detect in real time the horizontal or tilted posture of the aircraft part 10 after it is lifted by the lifting plate 16. The vision analysis and control system determines whether the aircraft part 10 is in a horizontal state and whether its center of gravity is centered, thereby deciding whether to push it into the first flip plate 61 (center of gravity centered) or the second flip plate 62 (center of gravity offset). That is, for the part in a horizontal balance state, the propulsion mechanism pushes it into the first flip plate 61, and for the part in a tilted state, the propulsion mechanism pushes it into the second flip plate 62. Then, the electric drive flip shaft 8 drives the corresponding flip plate to flip upward, so that the aircraft part 10 slides into the sliding track 7 and finally falls into the corresponding collection box or conveyor line.

[0040] The electric slider 3 continues to move forward or returns to its initial position. After the insertion rod 15 leaves the convex block 4, it resets under the action of gravity or spring. The lifting plate 16 descends back to its original position, waiting for the next weighing and screening cycle.

[0041] The working principle of this invention is as follows: First, the aircraft parts 10 to be screened and weighed are placed on the support frame body 9. At this time, the mass of the aircraft parts 10 placed on the support frame body 9 is weighed and marked by the electronic scale placed on the electric slider 3. Then, under the action of the braking system and the vision analysis and control system, the electric slider 3 is driven to slide on the slide rail 2 and slide to the position between the corresponding oppositely set first flip plate 61 and second flip plate 62. Therefore, according to the weighing, aircraft parts 10 of different masses are transported to the two oppositely set screening base bodies 5. The two oppositely set screening base bodies 5 are a homogeneous screening component, so aircraft parts 10 of different masses can be distinguished and transported to different homogeneous screening components. This makes it convenient to weigh and screen aircraft parts 10 of the same mass again in the future. It should be noted that the aircraft component 10 is a long metal frame. There are two types of aircraft components 10 with long metal frames: one type has its center of gravity located in the middle area of ​​the aircraft component 10, and the other type has its center of gravity deviating from the middle area of ​​the aircraft component 10. Both types of aircraft components 10 have the same mass. Traditional automatic weighing devices can only weigh and distribute aircraft components 10 with the same mass. This device can further subdivide and automatically weigh the components with their center of gravity located in the middle area of ​​the aircraft component 10 and those with their center of gravity deviating from the middle area of ​​the aircraft component 10.

[0042] After the aircraft part 10 is placed on the support frame body 9, the electronic scale weighs the aircraft part 10, and the vision analysis and control system distributes the corresponding aircraft part 10 to the corresponding homogeneous screening components. Therefore, it is only necessary to activate the braking system to drive the electric slider 3 to move to the corresponding position.

[0043] Then, the electric drive clamping member 11 is activated, allowing the two electric drive clamping members 11 to slide relative to each other and clamp the two ends of the aircraft accessory 10 placed on the rack body 9. Therefore, the aircraft accessory 10 clamped by the two electric drive clamping members 11 will be located in the middle of the rack body 9. Then, the electric drive clamping member 11 is returned to its original position, releasing the clamping effect of the electric drive clamping member 11 on the aircraft accessory 10.

[0044] Then, under the action of the braking system, the electric slider 3, carrying the aircraft accessory 10 on the support frame body 9, moves to the corresponding homogeneous screening component position, as shown in the reference. Figure 4In the state where the electric slider 3 moves, the insert rod 15, which slides coaxially inside the connecting tube 14, slides with the top of the slide rail 2. At this time, the top of the support plate and the top of the multiple lifting plates 16 set on the top of the insert rod 15 are located inside the insertion hole 17, and the lifting plates 16 do not protrude from the support frame body 9. Therefore, the lifting plates 16 will not lift the aircraft accessory 10 located on the support frame body 9.

[0045] During the movement of the electric slider 3, the insertion rod 15 slides onto the protruding block 4 on the slide rail 2, which then lifts the insertion rod 15 inside the connecting pipe 14. Therefore, the two types of accessories with their center of gravity located in the middle area of ​​the aircraft accessory 10 and accessories with their center of gravity deviating from the middle area of ​​the aircraft accessory 10 are automatically weighed and distributed. This will result in the following two states when the lifting plate 16 lifts the protruding insertion hole 17 and acts on the aircraft accessory 10: One reference Figure 5 In this state, the component with its center of gravity located in the middle area of ​​the aircraft component 10 is lifted by multiple lifting plates 16. The lifted area is located on the same vertical plane as the center of gravity of the aircraft component 10. At this time, the aircraft component 10 will be in a balanced state, that is, still in a horizontal state. The visual analysis and control system detects the horizontal state of the aircraft component 10 and pushes it onto the first flipping disk 61 under the action of the propulsion mechanism. Then, the screening base body 5 is opened and the first flipping disk 61 on the electric drive flipping shaft 8 is driven to flip, flipping the component with its center of gravity located in the middle area of ​​the aircraft component 10 and sliding it away along the sliding track 7. Second reference Figure 6 and Figure 7 In this state, the component whose center of gravity is off the middle area of ​​the aircraft component 10 is lifted by multiple lifting plates 16. The lifted area is not located on the same vertical plane as the center of gravity of the aircraft component 10, but is misaligned. Therefore, the component whose center of gravity is off the middle area of ​​the aircraft component 10 will be in a tilted state. The visual analysis and control system detects the tilted state of the aircraft component 10 and pushes it onto the second flipping plate 62 under the action of the propulsion mechanism. Then, the component whose center of gravity is off the middle area of ​​the aircraft component 10 is flipped over and slides away along the sliding track 7.

[0046] Therefore, based on the cooperation of the vision analysis control system and the braking system, the electric slider 3 moves the aircraft parts 10 to be screened and weighed to the corresponding homogeneous screening component position. Then, the vision analysis control system performs visual inspection on the parallel-set aircraft parts 10 and the aircraft parts 10 in the tilted state, and the propulsion mechanism further automatically pushes them to weigh and distinguish them.
