Description

Technical Field

[0001] This invention belongs to the field of automotive parts inspection technology, and relates to a visual inspection auxiliary device and a visual inspection system for automotive parts production. Background Technology

[0002] Automotive parts, also known as auto components, auto parts, or auto spare parts, refer to the components that make up the various units of a vehicle and all consumable materials that serve the vehicle. They are characterized by a wide variety, complex substitutions, complex identification systems, and rapidly fluctuating prices. From the perspective of automotive products, all system components, system assemblies, parts, components, and other related parts that constitute the entire vehicle are called automotive parts, including engine parts, transmission parts, braking system parts, steering system parts, running system parts, electrical and instrument system parts, body and accessories, and interior and exterior trim. They are diverse and can be classified from multiple aspects such as purpose, production source, material, installation location, and supply and sales relationships. According to purpose, they can be divided into essential parts, optional parts, decorative parts, and consumable parts. Typically, vehicle manufacturers use standardized codes for the parts used in manufacturing automobiles. The sources of parts include original equipment manufacturer (OEM) parts, aftermarket parts, licensed production parts (aftermarket parts), and other automotive parts (imitated parts).

[0003] Currently, some automotive parts on the market, such as bumpers, fenders, and side panels, require manual visual inspection during or after production. This involves placing the parts on a conveyor belt and conveying them forward, while workers stand on the side of the belt and visually inspect the parts for holes, protrusions, cracks, etc. Parts that pass inspection are then removed from the conveyor belt and placed on appropriate racks by workers at the end of the belt. However, because some parts, such as side panels, are large in size and weight, manually removing them from the conveyor belt is quite difficult for workers. Summary of the Invention

[0038] Lifting blocks, two of which are vertically arranged on the top of the transmission base plate;

[0039] The drive block is provided in two parts. The bottom of each drive block is provided with a hole that is movable and cooperates with the lifting block. The two drive blocks are located on both sides of the sliding seat. The bottom of the two drive blocks facing each other is a chamfered drive slope. Both sides of the sliding seat are passive slopes that fit into the drive slope.

[0040] The first elastic element is horizontally arranged on both sides of the sliding seat, and the free end of the first elastic element abuts against the transmission base on the corresponding side.

[0041] The present invention is further configured such that a buffer frame is horizontally arranged between the bottoms of the two swing supports, a plurality of buffer columns are vertically arranged on the top of the buffer frame, a buffer cylinder is vertically movably sleeved on the outer wall of each buffer column, an integral rod is horizontally arranged between two adjacent buffer cylinders, and a metal body is horizontally arranged between the tops of all the buffer cylinders.

[0042] It also includes a magnetic body and a fourth drive mechanism for driving the integrated rod to move up and down. The magnetic body is fixedly connected to the bottom of one end of all the swing plates. The magnetic body and the second gear are located on both sides of the swing shaft. When the receiving belt is in a horizontal state, the magnetic body is located above the metal body.

[0043] The present invention is further configured such that a long strip-shaped through-hole is vertically opened on the side of the conveying bracket, a second elastic element that is continuously compressed is vertically arranged at the bottom of the through-hole, and a lifting seat is vertically movably arranged inside the through-hole;

[0045] When the operating handle is rotated downwards, the metal body moves downwards, the bottom of the operating part abuts against the top of the driving block, and drives the driving block to move downwards until the first bevel tooth meshes with the second bevel tooth;

[0046] After the operating handle is released, the second elastic element drives the operating handle to swing upward until the upper side of the operating handle touches the top of the through-hole, and at this time the metal body is in its highest position.

Each auxiliary frame has an auxiliary cylinder rotatably mounted on its free end, and also includes an auxiliary belt. All the auxiliary cylinders are attached to the inner side of the auxiliary belt, which is located on the side of the bottom of all the lifting rollers.

[0049] The present invention also discloses a visual inspection system for automotive parts production, including a visual inspection auxiliary device as described in any of the preceding claims.

[0050] Compared with existing technologies, this invention provides a visual inspection auxiliary device and a visual inspection system for automotive parts production. Firstly, the upstream and / or downstream conveyor rollers, and the upstream and / or downstream receiving rollers, all have corresponding driving power (e.g., an electric motor), enabling both the conveyor belt and the receiving belt to rotate and convey the parts to be inspected downwards. During inspection, a worker is positioned on the side of the conveyor belt and inspects the parts. Parts that pass inspection move downstream to the receiving belt. At this point, the top of the receiving belt is not higher than the top of the conveyor belt; that is, the top of the receiving belt is at the same height as or lower than the top of the conveyor belt (but the height difference is small, preferably a maximum of 3 cm). This allows the parts to move smoothly from the conveyor belt to the receiving belt.

[0051] After the component moves onto the receiving belt, the first drive mechanism drives the swing shaft to rotate, while the receiving belt stops rotating until it tilts (during which the component remains relatively stationary with the receiving belt due to static friction) to a suitable angle. At this point, the worker can easily and conveniently remove the component from the receiving belt and place it on the side transfer trolley (not the object claimed in this application). The receiving belt then returns to a horizontal state and begins to rotate, awaiting the next component.

[0052] When removing and placing parts, the tilt of the conveyor belt makes it easier for workers to remove them, reducing the strain on their backs (for larger parts, workers typically need to bend over and stretch their arms to reach them). The tilt also makes it easier for workers to apply force, thus increasing the ease of operation and simplifying the removal of parts. Attached Figure Description

At this time, the top of the receiving belt 8 is not higher than the top of the conveyor belt 2; that is, the top of the receiving belt 8 is at the same height as or lower than the top of the conveyor belt 2 (but the height difference is small, preferably a maximum of 3 cm). This allows the parts to move smoothly from the conveyor belt 2 to the receiving belt 8.

[0111] After the component moves onto the receiving belt 8, the first drive mechanism drives the swing shaft 4 to rotate, while the receiving belt 8 stops rotating until it tilts to a suitable angle (during which the component remains relatively stationary with respect to the receiving belt 8 due to static friction). At this point, the worker can easily and conveniently remove the component from the receiving belt 8 and place it on the side transfer trolley (not the subject of this application). The receiving belt 8 then returns to a horizontal position and begins to rotate, awaiting the next component.

[0112] When removing and placing parts, the tilt of the receiving belt 8 makes it easier for workers to remove them, reducing the strain on their backs (for larger parts, workers typically need to bend over and stretch their arms to reach them). The tilted parts also make it easier for workers to apply force, thus increasing the ease of operation and simplifying the removal of parts.

[0113] In actual production, the upstream conveyor roller and / or the external motor driving it can be either the upstream receiving roller and / or the downstream receiving roller and the external motor driving it, or, as in this embodiment, the power of the receiving belt 8 comes from the downstream conveyor roller.

[0114] When components move on conveyor belt 2, the lifting roller 58 is inclined, thus the section of conveyor belt 2 containing the lifting roller 58 is also inclined. Therefore, when a component moves to the section containing the lifting roller 58, it will be in an inclined position. At this time, the worker is positioned on the side of the bottom of the lifting roller 58. Because the component is inclined, it is convenient for the worker to visually inspect it without having to bend down at a 90-degree angle, providing good protection for the worker's back. At the same time, the inclined component reduces the difficulty of observation for the worker, thus improving the quality of visual inspection. Furthermore, in actual use, different numbers of lifting rollers 58 can be set according to the size and complexity of the component, and different numbers of workers can be used to visually inspect the component. For example, if the component is relatively simple, only 1-2 workers are needed for inspection, and the number of lifting rollers 58 is also smaller. However, if the component is more complex or larger, more workers are needed for inspection, and the number of lifting rollers 58 is also larger. The lifting roller 58 is located in the middle of the conveyor support 1, that is, both ends of the conveyor belt 2 are horizontal, which facilitates the receiving of upstream components and the delivery of components to the receiving belt 8.

[0115] Furthermore, the bottom side of the lifting roller 58 is equipped with an auxiliary cylinder 60 and an auxiliary belt 61 to prevent parts from slipping. Even if the parts move downwards, they are supported and limited by the auxiliary cylinder 60; and the auxiliary belt 61 can be driven by the parts to move, allowing the parts to move smoothly downstream. The auxiliary cylinder 60 and auxiliary frame 59 primarily serve a safety function, ensuring that the parts remain relatively stationary with respect to the conveyor belt 2 during normal component transport.

[0116] When the receiving belt 8 is in standby mode, because the length of the long plate portion 6a is greater than the length of the short plate portion 6b, and the bottom of the free end of the long plate portion 6a has a magnetic body 50, the free end of the long plate portion 6a tends to swing downwards, thus making the top of the second gear 15 stably mesh with the bottom of the fourth gear 18. At this time, the first gear 14 drives the third gear 17 to rotate, the third gear 17 drives the fourth gear 18 to rotate through the first transmission belt 21, and the fourth gear 18 drives the second gear 15 to rotate. In this way, the upstream receiving roller can drive the receiving belt 8 to rotate, and the direction of movement of the top of the receiving belt 8 is the same as the direction of movement of the top of the conveyor belt 2. At this time, the top of the temporary plate 11 is lower than the top of the conveyor belt 2, so the parts can move directly from the conveyor belt 2 to the receiving belt 8.

[0117] After the component moves onto the receiving belt 8, it is preferable to apply the main gravity to the receiving belt 8 above the long plate portion 6a, so that the meshing between the second gear 15 and the fourth gear 18 is more stable, and the component can be transmitted more stably.

[0118] After the components have moved a certain distance on the receiving belt 8, the worker manually rotates the operating handle 56 downwards. During this rotation, the drive column 54 and the second eccentric wheel 55 both rotate, causing the integral rod 48, the buffer cylinder 47, and the metal body 49 (preferably made of copper, aluminum, or other materials that can generate Lenz's law with the magnetic body 50) to move downwards. The downward movement of the metal body 49 is to increase the distance between the metal body 49 and the magnetic body 50, which facilitates the subsequent separation of the magnetic body 50 from the metal body 49, thus allowing the swing shaft 4 to rotate.

[0119] As the worker continues to rotate the operating handle 56, the bottom of a certain node operating part 57 abuts against the top of the lower drive block 43, driving the drive block 43 to move downward. At this time, the drive block 43 drives the sliding seat 29 to move horizontally through the driving inclined surface. At the same time, the sliding table 30, sliding column 31, second bevel tooth 32, third bevel tooth 33, and synchronous column 34 all move horizontally until the second bevel tooth 32 meshes with the first bevel tooth 26. Then the second bevel tooth 32, sliding column 31, synchronous column 34, and synchronous cylinder 36 all rotate, and then drive the swing shaft 4 to rotate through the first transmission wheel 38, first linkage belt 41, second transmission wheel 39, second linkage belt 42, and third transmission wheel 40, causing the swing seat 5, swing plate 6, swing frame 7, and receiving belt 8 to tilt. At the same time, the first eccentric wheel 22 also rotates, raising the height of the temporary plate 11. Until the edge of the swing plate 6 is in contact with the positioning magnet 37, the operating handle 56 is released. Under the magnetic attraction of the positioning magnet 37, the swing plate 6 maintains a stable angle and position. At the same time, the receiving belt 8 does not rotate, making it easier for workers to remove tilted parts. The temporary plate 11 can act as a barrier to prevent subsequent parts from falling.

[0120] After the operating handle 56 is released, the second elastic element 52 drives the lifting seat 53 to move upward, and at the same time drives the operating handle 56 to swing upward until the operating handle 56 touches the top of the through hole 51. At this time, the metal body 49 returns to the highest position, and the top of the second eccentric wheel 55 is vertically touching the bottom of the integral rod 48. That is, even if the metal body 49 is subjected to a downward force, the angle of the second eccentric wheel 55 will not change, that is, the position of the metal body 49 will not change.

[0121] Moreover, when the operating part 57 is raised, the sliding seat 29 and the driving blocks 43 on both sides are restored to their initial positions under the elastic force of the two first elastic elements 44. That is, at this time, the second bevel tooth 32 and the third bevel tooth 33 are separated from the first bevel tooth 26.

[0122] After the parts are removed, the worker steps on the drive block 43 on the other side, causing the drive block 43 to drive the sliding seat 29 to move until the third bevel tooth 33 engages with the first bevel tooth 26. At this time, the swing shaft 4 rotates, causing the receiving belt 8 to rotate in a horizontal direction. In actual operation, since the positioning magnet 37 is still in an attracted state with the swing plate 6, the worker can simultaneously push the receiving belt 8 or the swing frame 7 to help the swing plate 6 separate from the positioning magnet 37. Subsequently, the worker can either release the foot on the drive block 43 or keep it pressed until the receiving belt 8 returns to a horizontal position.

[0123] If the swing plate 6 is released from the position magnet 37 shortly after separation, the swing plate 6 will swing downward under the action of gravity. When the magnetic body 50 approaches the metal body 49, an induced current and magnetic field will be generated in the metal body 49. The magnetic field will generate a repulsive force with the magnetic body 50, thereby buffering the descent of the magnetic body 50 and slowing down the descent speed of the swing plate 6 until the second gear 15 and the fourth gear 18 finally mesh.

[0124] However, if the pedal drive block 43 is kept in a state to make the swing plate 6 move, the swing plate 6 will swing down at a relatively stable speed, and during the swing process, the metal body 49 will also buffer the magnetic body 50, thereby reducing the collision between the second gear 15 and the fourth gear 18. The first transmission belt 21, the second transmission belt 25, the first linkage belt 41, and the second linkage belt 42 can all be either belts or chains (the other structures are matched; for example, if the first transmission belt 21 is a chain, then the first synchronous pulley 19 is a sprocket; if the second transmission pulley 39 is a sprocket, then there are two parallel and fixed sprockets, one connected to the first linkage belt 41 and the other connected to the second linkage belt 42). However, in this embodiment, the second linkage belt 42 is preferably a belt, and there is both pressure between the second linkage belt 42 and the second transmission pulley 39 and the third transmission pulley 40, and relative sliding can also occur. After the second gear 15 and the fourth gear 18 mesh, even if the second linkage belt 42 has a downward driving force for the swing plate 6, the relative sliding between the second linkage belt 42 and the third transmission pulley 40 can prevent excessive force from occurring between the second gear 15 and the fourth gear 18. If both the first linkage belt 41 and the second linkage belt 42 are chains, then after the second gear 15 and the fourth gear 18 mesh, the first bevel tooth 26 can also make the sliding seat 29 move until the first bevel tooth 26 and the third bevel tooth 33 separate, thereby preventing excessive stress from being generated between the second gear 15 and the fourth gear 18.

[0125] When the operation on the sliding seat 29 is released, the elastic force of the two first elastic elements 44 causes the first bevel tooth 26 to separate from the second bevel tooth 32 and the third bevel tooth 33. At the same time, as the swing shaft 4 rotates, the temporary plate 11 moves downward under the action of gravity, allowing the components on the conveyor belt 2 to move normally onto the receiving belt 8.

[0126] The entire operation process of this application is as follows: In the standby state, the receiving belt 8 rotates after being driven by the conveyor belt 2; after the receiving belt 8 receives the parts on the conveyor belt 2, the worker swings the operating handle 56 downwards, then the swing shaft 4 swings, causing the receiving belt 8 to stop rotating; after the swing plate 6 rotates a certain angle, the operating handle 56 is released, at which point the worker can easily and effortlessly remove the parts from the receiving belt 8. Then, the worker steps on the drive block 43, causing the swing shaft 4 to rotate until the receiving belt 8 returns to its original position. Simultaneously, the temporary plate 11 automatically lowers when not needed and automatically rises when needed. Furthermore, the distance between the metal body 49 and the magnetic body 50 is larger (automatically) when the magnetic body 50 swings upwards, thus producing a smaller effect; the distance is smaller (automatically) when the magnetic body 50 swings downwards, which can (automatically) generate a larger buffering force.

[0127] In another embodiment, the rotation of the swing shaft 4 and the rotation of the drive column 54 are both driven by motors. At the same time, there is a tension spring between the top of the lifting frame 9 and the bottom of the temporary plate 11 to facilitate the temporary plate 11 to return to its downward position. Similarly, there is a tension spring between the bottom of the integrated rod 48 and the buffer frame 45 to facilitate the downward movement of the integrated rod 48.

[0128] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0129] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
