Description

Technical Field

[0001] This invention relates to the field of automotive parts sorting technology, specifically to an automated visual sorting device for automotive parts using a screw. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. They are collectively referred to as automotive components. Among them, automotive parts are the foundation of the automotive industry. As a key fastener, the screw is made of high-strength materials, precision manufacturing, and strict standards to ensure the reliable connection and safe operation of various components. Different scenarios require the selection of appropriate materials, grades, and designs of screws to meet performance, durability, and safety requirements. Under normal circumstances, automotive screws are sorted before use to separate screws of different specifications together, so as to facilitate the unified handling, transportation, and use of automotive screws by subsequent staff.

[0003] According to the search, utility model with publication number CN221602577U discloses an automatic sorting device for automotive control button parts. This automatic sorting device for automotive control button parts includes a frame, a control terminal connected to one side of the frame, and a conveyor belt connected inside the frame. A misalignment device is rotatably connected inside the frame. A drive motor is fixedly connected to the side of the frame. A through-hole is opened in the side wall of the frame, through which the output end of the drive motor passes and is fixedly connected to the misalignment device. A support frame is fixedly connected to one side of the frame surface, and a scanner is fixedly connected to the support frame. This utility model, by changing the conveyor belt speed at the front of the sorting device, misaligns the conveyor belts that transport parts side by side. When parts transportation is busy, multiple parts often appear side by side. By using the misaligned conveyor belt speed to move the parts on the conveyor belt, the sorting device can sort them one by one, avoiding missorting and improving the accuracy of the equipment.

[0004] In existing technologies, before using screws in automotive parts, they are usually sorted to group screws of the same specifications into the same housing for subsequent use. Generally, cylinders are used to push and sort screws of the same specifications, and a conveyor belt is used to collect the remaining screws. Although cylinders can effectively sort screws during operation, when multiple screws are on the same coaxial line as the cylinder's output end, the operation and pushing of the cylinder can easily cause multiple screws to be pushed and sorted together. If the screws being pushed simultaneously are of different specifications, sorting errors can easily occur, thus reducing the effectiveness and accuracy of screw sorting.

[0005] Combining the above issues, we find that existing products on the market are difficult to avoid all of these problems simultaneously. Even if they can be solved, they require external tools, thus failing to achieve the desired results. Therefore, we propose an automated visual sorting device for automotive parts using screws.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention uses a first inclined plate and a second inclined plate to limit and guide the screws transported by the conveyor belt body. Simultaneously, a first servo motor drives a rotating disk to rotate, and the conveying grooves on the surface of the rotating disk transport the screws one by one, thus separating and transporting multiple stacked screws individually. This effectively reduces sorting errors caused by screws piling up. Furthermore, the rotation of the fixed ring block drives the cam to rotate intermittently, allowing the pusher plate to intermittently push the stacked screws, reducing the risk of jamming due to excessive screws. Finally, the combination of a machine vision detector and a cylinder enables the sorting and collection of screws of different specifications.

[0021] 2. This invention uses the rotation of the rotating ring block to drive the moving rod to move inside the arc-shaped groove. The moving rod can then drive the adjusting block to move inside the conveying groove via the mounting block, thereby adjusting the size of the conveying groove. This allows the conveying groove to transport and separate screws of different specifications as needed. At the same time, the intermeshing between the arc-shaped rack and the arc-shaped toothed plate limits the rotation of the rotating ring block, ensuring sufficient stability when not in use.

[0022] 3. This invention adjusts the height of the inclined guide plate by rotating the threaded rod, thereby separating and sorting larger screws first. Then, the second servo motor drives the moving block to move, so that the moving block can push the screws piled on one side of the collection plate through the feeding plate, so that they can fall smoothly into the inside of one of the collection boxes, thus realizing the first sorting of larger screws.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-9The present invention provides a technical solution: an automated visual sorting device for automotive parts using screws, comprising a conveyor belt frame 1, a conveyor belt body 12 connected to the inner cavity of the conveyor belt frame 1, a collection box 2 provided on the surface of the conveyor belt frame 1, three collection boxes 2 provided, a gantry frame 3, a placement frame 4 and a connecting frame 10 provided on the surface of the conveyor belt frame 1, a cylinder 13 fixedly connected to the top of the placement frame 4, a push plate 15 fixedly connected to the output end of the cylinder 13, a PLC controller 14 and a machine vision detector 16 fixedly connected to the surface of the gantry frame 3, and a separation mechanism 5 provided on the surface of the conveyor belt body 12.

[0035] As a further definition of the separation mechanism 5 of the present invention, the separation mechanism 5 includes a first inclined plate 501, the bottom of which is fixedly connected to the top of the conveyor belt frame 1. The first inclined plate 501 is used to guide the screw so that it can slide to the required position during transmission. A second inclined plate 502 is fixedly connected to the top of the conveyor belt frame 1. The second inclined plate 502 can cooperate with the first inclined plate 501 to effectively guide and transmit the screw, and allow the screw to be effectively piled up on one side of the second inclined plate 502. The top of the connecting frame 10 is fixedly connected to... The first servo motor 503 has its output end passing through the connecting frame 10 and fixedly connected to a connecting rod 504. One end of the connecting rod 504 is fixedly connected to a rotating disk 505, which is positioned between the first inclined plate 501 and the second inclined plate 502. Multiple conveying grooves 506 are provided on the surface of the rotating disk 505. The connecting frame 10 can connect to the connecting rod 504 via the first servo motor 503. When the first servo motor 503 is operating, it can smoothly drive the connecting rod 504 and the connecting rod... The rotating disk 505 connected to one end of 504 rotates. The conveying groove 506 on the surface of the rotating disk 505 can effectively cooperate with the second inclined plate 502 and the first inclined plate 501 to transmit power to the screw when the rotating disk 505 rotates. The surface of the connecting rod 504 is provided with a pushing component 508. An anti-drop plate 510 is fixedly connected to one side of the first inclined plate 501. A reset component 507 is provided on the top of the second inclined plate 502. The surface of the rotating disk 505 is fixedly connected with arc-shaped blocks 509. The number of arc-shaped blocks 509 is the same as the number of conveying grooves 506. The design of 509 effectively limits the screw being transported by the rotary disk 505 through the conveying groove 506. At the same time, the conveying groove 506 can use the rotation of the rotary disk 505 to transport the screws one by one, so that multiple screws can be transported evenly on the surface of the conveyor belt body 12, and multiple screws are less likely to be crowded together. The anti-drop plate 510 can limit the screws that are not transported by the conveying groove 506 and the rotary disk 505, so that they are less likely to slip off the surface of the conveyor belt body 12.

[0036] The pushing assembly 508 includes a fixed plate 5081, the inner cavity of which is fixedly connected to the surface of the connecting rod 504. A fixed ring block 5082 is fixedly connected to one side of the fixed plate 5081. A rotating rod 5083 is rotatably connected to the bottom of the connecting frame 10. An intermittent wheel 5084 and a cam 5085 are fixedly connected to the surface of the rotating rod 5083. The surface of the fixed ring block 5082 is slidably connected to the inner cavity of the intermittent wheel 5084. A pushing plate 5086 is provided on the surface of the cam 5085. The connecting rod 504 can install and fix the fixed ring block 5082 through the fixed plate 5081, while the connecting frame 10 can connect the intermittent wheel 5084 and the cam 5085 through the rotating rod 5083. When the connecting rod 504 rotates through the operation of the first servo motor 503, it can smoothly drive the fixed ring block 5082 to rotate continuously through the fixed plate 5081. The fixed ring block 5082 and the intermittent wheel 5084 are connected to push the intermittent wheel 5084, allowing it to rotate intermittently. Simultaneously, the intermittent rotation of the intermittent wheel 5084 drives the cam 5085 to rotate intermittently as well. After rotating to a certain angle, the cam 5085 pushes the pusher plate 5086, allowing it to move. When the pusher plate 5086 moves, it smoothly pushes the screws piled on one side of the anti-drop plate 510. This allows the pusher plate 5086 to push away the jammed screws when they are stuck between the first inclined plate 501 and the second inclined plate 502, preventing them from smoothly entering the conveying trough 506. This reduces the likelihood of multiple screws jamming, making screw separation and conveying smoother.

[0037] The reset assembly 507 includes a first mounting plate 5071, the bottom of which is fixedly connected to the top of a second inclined plate 502. A first slide rod 5073 is slidably connected to the inner cavity of the first mounting plate 5071. One end of the first slide rod 5073 is fixedly connected to one side of a push plate 5086. A first spring 5072 is fixedly connected between one side of the push plate 5086 and one side of the first mounting plate 5071. The first spring 5072 is sleeved on the surface of the first slide rod 5073. The second inclined plate 502 can connect the first spring 5072 and the first slide rod 5073 through the first mounting plate 5071. The first slide rod 5073 can connect the push plate 5086. When the push plate 5086 is pushed by the cam 5085, it can be smoothly reset by the elasticity of the first spring 5072, so as to facilitate subsequent movement. This allows the push plate 5086 to be used continuously and repeatedly.

[0038] The specific implementation of this embodiment is as follows: When it is necessary to separate, sort, and transport the screws, the operator can start the cylinder 13, the conveyor belt body 12, and the first servo motor 503. The conveyor belt body 12 can transport and transmit the screws. After the screws are transported to a certain distance, they will come into contact with the first inclined plate 501 and the second inclined plate 502. At this time, the first servo motor 503 will drive the connecting rod 504 and the rotating disk 505 to rotate through its own operation. During the rotation, the rotating disk 505 can drive and move the screws sequentially through the conveying groove 506. After rotating to a certain angle, the screws are released sequentially through the transport of the conveyor belt body 12, so that multiple screws can be transported one by one from multiple stacked situations. During the transmission process, the rotating disk 505 can improve the stability of the screw rotation and transport through the arc block 509. Afterwards, the screws transported by the conveyor belt body 12 will pass under the machine vision detector 16. At the same time, the machine vision detector 16 and the cylinder All cylinders 13 are electrically connected to the PLC controller 14. This ensures that after the screw passes under the machine vision detector 16, it will be recognized by the machine vision detector 16, and the cylinder 13 will push the screw of the required size, causing it to fall into one of the collection boxes 2. The screws that are not pushed will fall smoothly into the other collection box 2. At the same time, the machine vision detector 16 can be selected according to the actual situation, such as XG-7700. While the connecting rod 504 is rotating, The fixed ring block 5082 can be rotated by the fixed plate 5081, and the connection between the fixed ring block 5082 and the intermittent wheel 5084, and the connection between the intermittent wheel 5084 and the rotating rod 5083, can drive the cam 5085 to move intermittently, thereby realizing the intermittent pushing of the push plate 5086. After being pushed, the push plate 5086 can push the screws piled up on one side of the anti-drop plate 510, thereby reducing the situation where multiple screws pile up on one side of the anti-drop plate 510 and get stuck together.

[0039] Example 2: Please refer to Figures 1-9 The present invention provides a technical solution: an automated visual sorting device for automotive parts using a screw. The present invention makes corresponding improvements to the technical problems mentioned in the background art. An adjustment mechanism 7 is provided on the top of the separation mechanism 5.

[0040] As a further definition of the adjustment mechanism 7 of the present invention, the adjustment mechanism 7 includes a fixed rod 701, one end of which is fixedly connected to the top of the rotating disk 505. A rotating ring block 702 is rotatably connected to the top of the rotating disk 505. An arc-shaped groove 708 is formed on the top of the rotating ring block 702. Multiple arc-shaped grooves 708 are provided. A moving rod 704 is slidably connected to the inner cavity of each of the multiple arc-shaped grooves 708. An installation block 705 is fixedly connected to one end of each of the multiple moving rods 704. An adjustment block 706 is fixedly connected to one side of each of the multiple installation blocks 705. The number of adjustment blocks 706 is the same as the number of conveying grooves 506. The multiple adjustment blocks 706 correspond one-to-one with the multiple conveying grooves 506. A fixed round block 703 is fixedly connected to one end of the fixed rod 701. The surfaces of the multiple moving rods 704 are slidably connected to the inner cavity of the fixed round block 703. A limiting component 707 is provided on the top of the rotating disk 505. 05 enables the connection between the fixed rod 701 and the rotating ring block 702, while the fixed rod 701 connects to the fixed circular block 703. The rotating ring block 702 connects to the moving rod 704 via the arc groove 708, and the moving rod 704 can be mounted on the adjusting block 706 using the mounting block 705. The sliding connection between the moving rod 704 and the fixed circular block 703 allows the moving rod 704 to slide smoothly inside the fixed circular block 703 when the rotating ring block 702 rotates, thereby causing the moving rod 704 and the mounting block 705 to move. At the same time, due to the connection between the mounting block 705 and the adjusting block 706, the size of the conveying trough 506 can be smoothly adjusted when the adjusting block 706 moves inside the conveying trough 506, thus enabling the rotary disk 505 to separate and sort screws of more different specifications.

[0041] The limiting component 707 includes a second mounting plate 7071, one side of which is fixedly connected to the top of the rotating disk 505. A second slide rod 7072 is slidably connected to the inner cavity of the second mounting plate 7071. An arc-shaped rack 7074 is fixedly connected to one side of the second slide rod 7072. An arc-shaped toothed plate 7075 is fixedly connected to the surface of the rotating ring block 702. The teeth of the arc-shaped rack 7074 mesh with the teeth of the arc-shaped toothed plate 7075. A third spring 7073 is fixedly connected between one side of the second mounting plate 7071 and one side of the arc-shaped rack 7074. The rotating disk 505 can be controlled by the second mounting plate 7071. The second slide rod 7072 is connected to the third spring 7073, which in turn cooperates with the second slide rod 7072 to install the arc-shaped rack 7074. The intermeshing between the arc-shaped rack 7074 and the arc-shaped toothed plate 7075 allows the rotating ring block 702 to be smoothly limited by the arc-shaped rack 7074 when it does not need to be rotated. When it is necessary to rotate the rotating ring block 702, the second slide rod 7072 is simply pulled to move the arc-shaped rack 7074, thus removing the limitation on the arc-shaped toothed plate 7075 and the rotating ring block 702.

[0042] The specific implementation method of this embodiment is as follows: When it is necessary to adjust the screw specifications that can be separated and sorted by the conveying trough 506 and the rotating disk 505, the operator can first pull the second slide bar 7072, so that the second slide bar 7072 drives the arc-shaped rack 7074 to move, and cancel the meshing between the arc-shaped rack 7074 and the arc-shaped toothed plate 7075. Then, rotate the rotating ring block 702. When the rotating ring block 702 rotates, it can utilize the sliding between the arc-shaped groove 708 opened on one side and the moving rod 704. The connection is made by pushing the moving rod 704, which allows the mounting block 705 and the adjusting block 706 to move. When the adjusting block 706 moves, the size inside the conveying groove 506 can be adjusted. After the position adjustment of the adjusting block 706 is completed, the pull on the second sliding rod 7072 can be released. At this time, the elasticity of the third spring 7073 can drive the arc-shaped rack 7074 to reset and engage and limit the arc-shaped toothed plate 7075, thereby limiting the rotating ring block 702.

[0043] Example 3: Please refer to Figures 1-9 The present invention provides a technical solution: an automated visual sorting device for automotive parts using screws. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The surface of the conveyor belt body 12 is provided with a feeding mechanism 8 and a sorting mechanism 9.

[0044] As a further definition of the sorting mechanism 9 and the unloading mechanism 8 of the present invention, the sorting mechanism 9 includes a fixed frame 901, the bottom of which is fixedly connected to the top of the conveyor belt frame 1. An inclined guide plate 905 is slidably connected to one side of the fixed frame 901. The inclined guide plate 905 is used to sort the screws, so that larger screws can be sorted out first. A threaded rod 902 is rotatably connected to the top of the fixed frame 901. Two limit plates 903 are fixedly connected to the top of the fixed frame 901. Three moving plates 904 are fixedly connected to the top of the inclined guide plate 905. The inner cavity of one moving plate 904 is threadedly connected to the surface of the threaded rod 902, and the inner cavities of the other two moving plates 904 are slidably connected to the surface of the limit plate 903. Next, a rotating rod 906 is rotatably connected to one side of the fixed frame 901, and a collecting plate 907 is fixedly connected to the surface of the rotating rod 906. The fixed frame 901 can connect the threaded rod 902 and the limiting plate 903. The two limiting plates 903 can limit the inclined guide plate 905 through two moving plates 904. At the same time, the threaded rod 902 can drive the inclined guide plate 905 to move up and down when rotating through another moving plate 904. The gap between the inclined guide plate 905 and the surface of the conveyor belt body 12 can sort and block larger screws first, making it difficult for them to be conveyed to the rear. The collecting plate 907 connected to one side of the fixed frame 901 through the rotating rod 906 can temporarily block and store the larger screws that have been sorted and blocked.

[0045] The unloading mechanism 8 includes a third mounting plate 801. One side of the third mounting plate 801 is fixedly connected to one side of the conveyor belt frame 1. A second servo motor 802 is fixedly connected to the top of the third mounting plate 801. A T-block 803 is fixedly connected to the output end of the second servo motor 802. A connecting rod 804 is rotatably connected to the top of the T-block 803. A mounting rod 805 is rotatably connected to the inner cavity of the connecting rod 804. A moving block 806 is fixedly connected to one end of the mounting rod 805. An unloading plate 807 is fixedly connected to one side of the moving block 806. A limit component 808 and a rotation component 809 are provided on the surface of the moving block 806. The conveyor belt frame 1 can move the second servo motor 802 through the third mounting plate 801. The second servo motor 802 can connect to the connecting rod 804 via the T-block 803. The connecting rod 804 can use its connection with the mounting rod 805 to install and connect the moving block 806. When the second servo motor 802 is operating, it can smoothly drive the T-block 803 to rotate, and use the rotation of the T-block 803 to push the connecting rod 804, so that the connecting rod 804 can use the mounting rod 805 to push the moving block 806 and the feeding plate 807 on one side of the moving block 806. When moving, the feeding plate 807 can push the larger screws piled on one side of the feeding plate 807, so that they can fall into the interior of one of the collection boxes 2.

[0046] The limiting component 808 includes a third inclined plate 8083. The bottom of the third inclined plate 8083 is fixedly connected to the top of the conveyor belt frame 1. A fixing block 8081 is fixedly connected to one side of the third inclined plate 8083. A limiting block 8082 is fixedly connected to one side of the fixing block 8081. The inner cavity of the limiting block 8082 is slidably connected to the surface of the moving block 806. The conveyor belt frame 1 can install and connect the limiting block 8082 through the fixing block 8081. At the same time, the third inclined plate 8083 connected to one side of the limiting block 8082 can smoothly and effectively limit the moving block 806, so that the moving block 806 can be sufficiently stable and smoothly perform linear movement when pushed by the mounting rod 805. The third inclined plate 8083 can guide the screw placed on the surface of the conveyor belt body 12 for transmission, so that it can contact the inclined guide plate 905 more smoothly.

[0047] The rotating assembly 809 includes a movable rack 8091, one side of which is fixedly connected to one side of a movable block 806. A gear 8092 is fixedly connected to the surface of the rotating rod 906. A fourth spring 11 is fixedly connected to the inner cavity of the feed plate 807, and a sliding inclined plate 6 is fixedly connected to one end of the fourth spring 11. The movable block 806 can mount the movable rack 8091, and while the movable block 806 is moving, it can smoothly drive the movable rack 8091 to move together. When the movable rack 8091 moves with the movable block 806, it can first engage with... Gear 8092 meshes and drives rotating rod 906 to rotate, thereby causing collecting plate 907 to flip, allowing the larger screws piled on one side of collecting plate 907 to fall more smoothly into one of the collecting boxes 2. At the same time, the feeding plate 807 can be connected to sliding inclined plate 6 by fourth spring 11. Sliding inclined plate 6 can be tightly fitted to one side of inclined guide plate 905 by the elasticity of fourth spring 11, thereby reducing the possibility of gaps between feeding plate 807 and inclined guide plate 905 due to one side of inclined guide plate 905 being set as an inclined surface.

[0048] The specific implementation of this embodiment is as follows: When it is necessary to sort larger screws first, the threaded rod 902 can be rotated first. Based on the screw's size, the threaded rod 902 can use its own rotation to move the inclined guide plate 905 down to the required and appropriate position. Then, the screws placed on the surface of the conveyor belt body 12 will be conveyed and come into contact with the inclined guide plate 905. At this time, the larger screws will be restricted and obstructed by the inclined guide plate 905, while the smaller screws will slide out from the bottom of the inclined guide plate 905. Then, due to the inclined surface of the inclined guide plate 905, the larger screws will accumulate on one side of the collecting plate 907. After this, the operator can start the second servo motor 802. The movement of the second servo motor 802 drives the T-block 803 to rotate, and the rotation of the T-block 803 drives the connecting rod 804 to rotate. When the connecting rod 804 rotates, it can smoothly push the moving block 806 and the feeding plate 807 through the mounting rod 805. During the movement, the moving block 806 can smoothly push the gear 8092 through the moving rack 8091, causing the collecting plate 907 to rotate. In conjunction with the movement of the feeding plate 807, the larger screw is pushed, so that it can fall smoothly into the inside of one of the collecting boxes 2.
