Description

Technical Field

[0001] This utility model belongs to the field of metal wire detection technology, specifically relating to a fully automatic high-precision dynamic detection device for surface defects of aluminum alloy welding wire. Background Technology

[0002] Aluminum alloy welding wire is a commonly used metal wire, and it often requires inspection after processing. After processing, aluminum alloy welding wire is usually wound into a whole coil. It is first straightened by a straightening device, then cleaned, and then cut by a shearing device before inspection. Existing patent CN214718914U discloses a flaw detection device that is less likely to damage copper-clad aluminum wire, including a cleaning tank with a guide roller rotatably connected inside. The cleaning tank is equipped with an air washing mechanism, which includes an air jet pipe with air jet holes facing the wire. Existing flaw detection devices first clean the material and then inspect it with a flaw detector. Because the wire is continuously moving, the flaw detector also continuously inspects it. When the flaw detector detects a problem, it can only analyze that this section of the wire is faulty; it cannot accurately detect the defective area, resulting in low detection accuracy. Therefore, a fully automatic, high-precision, dynamic detection device for surface defects of aluminum alloy welding wire is needed to overcome these difficulties. Summary of the Invention

[0003] This utility model addresses the problems existing in the prior art by disclosing a fully automatic, high-precision, dynamic detection device for surface defects of aluminum alloy welding wire. This utility model feeds materials sequentially through a material distribution component and performs multi-angle detection through a detection camera on the detection component, resulting in high detection accuracy and good controllability.

[0004] The objective of this invention is achieved through the following technical solution: a fully automatic high-precision dynamic detection device for surface defects of aluminum alloy welding wire, comprising a first feeding device and a second feeding device arranged sequentially, with a transfer device for transferring materials between the first and second feeding devices; a material distribution component for sequential feeding is provided directly above the first feeding device, the material distribution component including a loading trough, the loading trough being located close to the first feeding device; a detection component is provided directly above the second feeding device, the detection component including a detection bracket and a slider, the slider being movable along the axial direction of the detection bracket relative to the material, and a pair of detection cameras being provided on the slider; lifting cylinders are provided on both sides of the detection bracket, and when the detection cameras are working, the lifting cylinders control the material to detach from the second feeding device.

[0005] Preferably, the material dispensing assembly further includes a first cylinder and a second cylinder arranged in pairs. A cylinder bracket is fixedly installed on the side of the loading trough, and the first cylinder and the second cylinder are provided on the cylinder bracket. A first limiting plate is provided on the piston shaft of the first cylinder, and a second limiting plate is provided on the piston shaft of the second cylinder.

[0006] Preferably, the first limiting plate and the second limiting plate are arranged side by side, and the loading trough includes a vertical material dropping section; the outer contour of the vertical material dropping section is adapted to the outer contour of the material, and the material is a metal cylinder; the vertical distance between the first limiting plate and the second limiting plate is adapted to the outer diameter of the material.

[0007] Preferably, the material distribution assembly further includes a material distribution bracket, on which a material loading groove is fixedly installed; a first limiting cylinder is fixedly installed on the material distribution bracket, and a first push plate is provided on the piston shaft of the first limiting cylinder; the first limiting cylinders are arranged in pairs on the left and right sides of the first feeding device, and the first push plate is arranged adjacent to the material.

[0008] After being cut by the shearing device, the aluminum alloy welding wires fall sequentially into the loading trough, and then fall sequentially along the inclined surface of the loading trough into the vertical dropping section, so that each aluminum alloy welding wire is arranged side by side. The first limiting plate is directly above the second limiting plate. In the default initial state, the lowest aluminum alloy welding wire in the vertical dropping section abuts against the second limiting plate. The second to last aluminum alloy welding wire is arranged adjacent to the lowest aluminum alloy welding wire and abuts against the first limiting plate. At this time, both the first and second cylinders are in the extended state. Then, the second cylinder controls the second limiting plate to extend and retract once. In this way, the lowest aluminum alloy welding wire will fall onto the first feeding device. At this time, the second limiting plate is in the extended state. Then, the first cylinder controls the first limiting plate to extend and retract once, so the second to last aluminum alloy welding wire in the initial state will fall and abut against the second limiting plate. At the same time, a new aluminum alloy welding wire is separated by the first limiting plate. Then, through the reciprocating extension and retraction of the first and second limiting plates, the aluminum alloy welding wires can fall onto the first feeding device in sequence.

[0009] Preferably, the detection assembly further includes a pair of drive motors and lead screws, and the sliders are arranged in pairs on the detection bracket; the detection bracket is provided with a limiting groove, and a slider is slidably connected to the limiting groove; the lead screw is rotatably connected to the detection bracket, and the lead screw and the slider mesh with each other; a drive motor is mounted on the side of the detection bracket, and the motor shaft of the drive motor is connected to the lead screw; each slider is provided with a pair of detection cameras, and material is placed between the two detection cameras; a pair of lifting cylinders are provided on the inner side of the detection bracket, and the lifting cylinders are arranged adjacent to the end of the material.

[0010] Preferably, a support member is fixedly installed on the piston shaft of the lifting cylinder, and the outer contour of the support member is adapted to the outer contour of the material; the detection bracket is also provided with a pair of second limiting cylinders, and a second push plate is provided on the piston shaft of the second limiting cylinder, with the second push plate facing the material.

[0011] Preferably, the detection bracket is provided with a limiting groove, and the slider is slidably installed in the limiting groove. The outer contour of the limiting groove is adapted to the outer contour of the limiting groove. A second feeding device is provided below the detection bracket. The second feeding device includes a second conveyor belt. The second conveyor belt is provided with a plurality of uniform linear second dividing protrusions. The front-to-back distance between the two limiting grooves is adapted to the front-to-back distance between the two second dividing protrusions.

[0012] When the second feeding device transports the aluminum alloy welding wire to directly below the inspection bracket, the two rows of lifting cylinders simultaneously control the extension of the support components, causing the two aluminum alloy welding wires to detach from the second feeding device. Then, the second limiting cylinder controls the extension of the second push plate, aligning the aluminum alloy welding wires and limiting their ends. Next, the drive motor starts working, driving the lead screw to rotate. As the lead screw rotates, the slider moves axially along the limiting groove. The slider is equipped with paired inspection cameras, allowing for precise all-around inspection of the aluminum alloy welding wire. After the inspection is completed, the second push plate and support components automatically reset, and the aluminum alloy welding wire automatically falls onto the second feeding device. Due to the second separating protrusion on the second conveyor belt, each aluminum alloy welding wire can be separated. A multi-axis robotic arm is located on the side of the inspection bracket (not shown in the accompanying drawings). When an aluminum alloy welding wire is detected as defective, the multi-axis robotic arm automatically removes the defective product from the second conveyor belt. Since the testing bracket can test two aluminum alloy welding wires at the same time, the testing efficiency is higher. After the two aluminum alloy welding wires are tested, the aluminum alloy welding wires automatically fall onto the second feeding device. Then, a new aluminum alloy welding wire is tested, so the testing process can continue.

[0013] Preferably, the first feeding device includes a first motor, a first conveyor belt, and a first support; the first conveyor belt is rotatably connected to the first support, and the first motor drives the first conveyor belt to rotate relative to the first support when it is working; the first conveyor belt is provided with a plurality of uniformly linearly distributed first dividing protrusions; the second feeding device includes a second motor, a second conveyor belt, and a second support; the second conveyor belt is rotatably connected to the second support, and the second motor drives the second conveyor belt to rotate relative to the second support when it is working; the second conveyor belt is provided with a plurality of uniformly linearly distributed second dividing protrusions; the first conveyor belt and the second conveyor belt are staggered vertically, and a transfer device for transferring materials is provided between the first conveyor belt and the second conveyor belt.

[0014] Preferably, the second bracket is provided with a pair of third limiting cylinders at the end near the transfer device, and a pair of third push plates are provided on the piston shaft of the third limiting cylinder; the transfer device includes a mounting bracket and a rotating component, the rotating component is rotatably connected to the mounting bracket, and a third motor is provided below the mounting bracket, which drives the rotating component to rotate relative to the mounting bracket when it is working; the rotating component includes a pair of turntables, and the turntables are provided with circumferentially arrayed material drop grooves, the outer contour of the material drop grooves being adapted to the outer contour of the material.

[0015] When the first motor operates, it drives the first conveyor belt to rotate relative to the first support. When the second motor operates, it drives the second conveyor belt to rotate relative to the second support. Then, when the third motor operates, it drives the rotating component to rotate relative to the mounting bracket. When the aluminum alloy welding wire on the first conveyor belt approaches the rotating component, the aluminum alloy welding wire will automatically fall into the material drop trough of the turntable. As the rotating component continues to rotate, the aluminum alloy welding wire will fall onto the second conveyor belt in sequence. A third limit cylinder is provided at the initial end of the second feeding device. The operation of the third limit cylinder controls the third push plate to approach the aluminum alloy welding wire, so that the aluminum alloy welding wire can be automatically aligned, thereby facilitating subsequent testing of the testing component.

[0016] Compared with the prior art, the present invention has the following advantages: 1. By setting a transfer device between the first feeding device and the second feeding device, the aluminum alloy welding wire can be transferred on two water lines, resulting in high transfer efficiency; 2. By setting a material distribution component above the first feeding device, the aluminum alloy welding wire can fall onto the first feeding device sequentially and continuously; 3. By simultaneously detecting the two aluminum alloy welding wires through the detection component, the detection efficiency is higher; 4. By setting two detection cameras on both sides of the aluminum alloy welding wire for detection, the detection cameras can move relative to the aluminum alloy welding wire, resulting in higher detection accuracy and better controllability.

A second feeding device 2 is provided below the detection bracket 51, the second feeding device 2 including a second conveyor belt 22, and the second conveyor belt 22 is provided with several uniformly linear second dividing protrusions 24. The front-to-back distance between the two limiting grooves 56 is adapted to the front-to-back distance between the two second dividing protrusions 24.

[0030] The first feeding device 1 includes a first motor 11, a first conveyor belt 12, and a first support 13; the first conveyor belt 12 is rotatably connected to the first support 13, and when the first motor 11 is working, it drives the first conveyor belt 12 to rotate relative to the first support 13; the first conveyor belt 12 is provided with a plurality of uniformly linearly distributed first dividing protrusions 14; the second feeding device 2 includes a second motor 21, a second conveyor belt 22, and a second support 23; the second conveyor belt 22 is rotatably connected to the second support 23, and when the second motor 21 is working, it drives the second conveyor belt 22 to rotate relative to the second support 23; the second conveyor belt 22 is provided with a plurality of uniformly linearly distributed second dividing protrusions 24; the first conveyor belt 12 and the second conveyor belt 22 are staggered vertically, and a transfer device 3 for transferring materials is provided between the first conveyor belt 12 and the second conveyor belt 22. The second bracket 23 is provided with a pair of third limiting cylinders 8 near the transfer device 3.

The turntables 34 are provided with a circular array of material drop troughs 35. The outer contour of the material drop troughs 35 is adapted to the outer contour of the material.

[0031] The specific operation process of this embodiment is as follows: After being cut by the shearing device, the aluminum alloy welding wires fall sequentially into the loading groove 41, and then fall sequentially along the inclined surface of the loading groove 41 into the vertical dropping section 46, so that each aluminum alloy welding wire is arranged side by side. The first limiting plate 44 is directly above the second limiting plate 45. In the default initial state, the lowest aluminum alloy welding wire in the vertical dropping section abuts against the second limiting plate 45; the second to last aluminum alloy welding wire is arranged adjacent to the lowest aluminum alloy welding wire, and the second to last aluminum alloy welding wire abuts against the first limiting plate 44; at this time, the first cylinder 42 and the second cylinder 43 are both in the extended state, and then the second cylinder 43 controls the second limiting plate 45 to extend and retract once; thus, the lowest aluminum alloy welding wire... The aluminum alloy welding wire falls onto the first feeding device 1, at which point the second limiting plate 45 is extended. Then, the first cylinder 42 controls the first limiting plate 44 to extend and retract once, causing the penultimate aluminum alloy welding wire to fall and abut against the second limiting plate 45. Simultaneously, a new aluminum alloy welding wire is separated by the first limiting plate 44. Then, through the reciprocating extension and retraction of the first limiting plate 44 and the second limiting plate 45, the aluminum alloy welding wires continuously fall onto the first feeding device 1. When the aluminum alloy welding wire falls onto the first feeding device 1, the first limiting cylinder 48 controls the first push plate 49 to extend, automatically aligning the aluminum alloy welding wires for easy transfer by the subsequent transfer device 3.

[0032] When the first motor 11 is working, it drives the first conveyor belt 12 to rotate relative to the first support 13. When the second motor 21 is working, it drives the second conveyor belt 22 to rotate relative to the second support 23. Then, when the third motor 33 is working, it drives the rotating component 32 to rotate relative to the mounting bracket 31. When the aluminum alloy welding wire on the first conveyor belt 12 approaches the rotating component 32, the aluminum alloy welding wire will automatically fall into the material drop trough 35 of the turntable 34. As the rotating component 32 continues to rotate, the aluminum alloy welding wire will fall onto the second conveyor belt 22 in sequence. A third limiting cylinder 8 is provided at the initial end of the second feeding device 2. The operation of the third limiting cylinder 8 controls the third push plate 9 to approach the aluminum alloy welding wire, so that the aluminum alloy welding wire can be automatically aligned, thereby facilitating the subsequent inspection of the inspection component 5.

[0033] When the second feeding device 2 transports the aluminum alloy welding wire to the underside of the detection bracket 51, the two rows of lifting cylinders 6 will simultaneously control the support 7 to extend, so that the two aluminum alloy welding wires will be separated from the second feeding device 2; then the second limiting cylinder 57 controls the second push plate 58 to extend, so that the aluminum alloy welding wires are aligned with each other and the ends of the aluminum alloy welding wires are limited. Next, the drive motor 54 starts working, driving the lead screw 55 to rotate. When the lead screw 55 rotates, the slider 52 moves axially along the limiting groove 56. The slider 52 is equipped with a pair of detection cameras 53, allowing for precise all-around detection of the aluminum alloy welding wire. After the aluminum alloy welding wire is detected, the second push plate 58 and the support 7 automatically reset, and the aluminum alloy welding wire automatically falls onto the second feeding device 2. Because the second conveyor belt 22 has a second separating protrusion 24, each aluminum alloy welding wire can be separated. A multi-axis robotic arm is located on the side of the detection bracket 51 (not shown in the accompanying drawings). When an aluminum alloy welding wire is detected as defective, the multi-axis robotic arm automatically removes it from the second conveyor belt 22. Since the detection bracket 51 detects two aluminum alloy welding wires simultaneously, the detection efficiency is higher. After two aluminum alloy welding wires are detected, they automatically fall onto the second feeding device 2. Then, a new aluminum alloy welding wire is detected, allowing the detection process to continue continuously.
