Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum rod production, and particularly relates to an aluminum rod conveying system. Background Art

[0002] Aluminum is a light metal, and its compounds are widely distributed in nature. The aluminum resources in the earth's crust are about 40 - 50 billion tons, ranking third after oxygen and silicon. It is the largest category of metal among metal varieties. An aluminum rod is a long strip of metal material made of aluminum or aluminum alloy, and is usually applied to industrial manufacturing, construction and structure, transportation, etc.

[0003] After the aluminum rod is formed, it needs to be heat - treated. The core purpose is to optimize the microstructure and mechanical properties of the material by controlling temperature and time. Currently, when conveying the heated and cooled aluminum rod, generally a conveyor belt is used for handling and conveying. Aluminum will form a dense aluminum oxide protective film at room temperature to prevent further oxidation of the aluminum surface. When aluminum is heated, especially in a high - temperature environment, the oxidation reaction will intensify, and a relatively thick oxide layer may be formed. In order to ensure the quality of the aluminum material, generally the oxide layer on its surface needs to be removed.

[0004] Most of the existing aluminum rod conveying systems can only convey the aluminum rods after the oxide layer is manually cleaned. The existing conveying systems cannot detect the quality of the aluminum rods after manual cleaning, so it is impossible to ensure that all the conveyed aluminum rods are qualified products. When unqualified aluminum rods are transported to other processes for processing, they still need to be taken out and reworked, which greatly reduces the production efficiency of aluminum rods. This phenomenon has become an urgent problem for those in this field. Summary of the Invention

[0019] The technical solution of the present invention will be further described in detail and non - restrictively below in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-9 , the present invention provides a technical solution: an aluminum rod conveying system, including a workbench 1 and a controller 12 arranged on the workbench 1. A conveying system 2 is arranged on the workbench 1, and the conveying system 2 includes a feeding conveyor belt 21, a return conveyor belt 22, and a discharging conveyor belt 23; The workbench 1 is of a frame structure. A robot arm 11 is arranged inside the workbench 1, and the robot arm 11 is used for clamping aluminum rods; a grinding box 6 is arranged inside the workbench 1, and an oxide layer removing component is arranged in the grinding box 6; The oxide layer removing component includes a grinding unit and a clamping unit; The grinding unit includes an adjusting drive 61, and the adjusting drive 61 is fixedly connected to the inner walls of the four sides of the grinding box 6. The output end of the adjusting drive 61 is fixedly connected with a mounting frame 63. One side of the mounting frame 63 is fixedly connected with a grinding drive 66. A grinding roller 62 is arranged in the mounting frame 63. The output end of the grinding drive 66 is fixedly connected with one end of the grinding roller 62, and the other end of the grinding roller 62 is rotatably connected to the other side of the mounting frame 63.

[0021] The clamping unit includes a rotating drive 65, and the rotating drive 65 is fixedly connected to the outer wall of the grinding box 6. The output shaft of the rotating drive 65 penetrates through the side wall of the grinding box 6 and is fixedly connected with a grinding clamping disc 64, and the grinding clamping disc 64 is located in the middle of the grinding box 6.

[0022] Refer to Figure 2 . Figure 3 And Figure 4, on the four sides inside the grinding box 6, the adjusting driving parts 61 drive the mounting frames 63 on the same side to move through the telescoping of their output ends, indirectly driving the four-side grinding rollers 62 to move towards the aluminum rod. The rotation of the output shaft of the grinding driving part 66 drives the grinding rollers 62 to rotate in the mounting frames 63, and the four-side rotating grinding rollers 62 are used to remove the oxide layer on the surface of the aluminum rod.

[0023] It should be noted that displacement sensors are installed on the four-side adjusting driving parts 61 (the displacement sensors are prior art and not shown in the figure), which feedback the position of the piston rod in the adjusting driving part 61 to the controller 12 in real time. And the pneumatic circuit of each adjusting driving part 61 is independently configured with a proportional flow valve, and the intake air flow is adjusted by the analog signal (0~10V) output by the controller 12; Designate one adjusting driving part 61 as the main cylinder, and the other three adjusting driving parts 61 as slave cylinders. The controller 12 compares the displacement difference between the main and slave cylinders in real time and dynamically adjusts the opening of the proportional valve of the slave cylinder to achieve follow-up synchronization.

[0024] Input the diameter of the aluminum rod, the controller 12 calculates the target displacement of each adjusting driving part 61. The main cylinder moves at a set speed, and the slave cylinders are dynamically adjusted according to the displacement difference. The control quantity is output to the proportional valve in real time through the built-in algorithm program to correct the speed of the slave cylinders. When the main cylinder contacts the aluminum rod, the displacement is finely adjusted through the air cylinder air pressure feedback (pressure sensor) to ensure that the pressure of the four-side grinding rollers 62 is balanced and they are in contact with the aluminum rod.

[0025] It should be noted that the adjusting driving part 61 can be a cylinder, and the rotating driving part 65 and the grinding driving part 66 can be motors.

[0026] It should be added that the grinding clamping disc 64 is prior art (such as a pneumatic three-jaw chuck), and the robotic arm 11 is prior art (such as an industrial robotic arm). The two respectively control the clamping and picking of the aluminum rod through the programs built in the controller 12, and their working principles will not be elaborated too much in this application text.

[0027] A detection box 5 is arranged inside the workbench 1, and a detection component is arranged in the detection box 5. The detection component includes a smoothness detection unit, a straightness detection unit, and a surface defect detection unit; The smoothness detection unit is used to detect whether the oxide layer on the surface of the aluminum rod is completely removed. The smoothness detection unit includes a detection mechanism and a fixing mechanism; The detection mechanism includes a detection driving member 7, which is fixedly connected to the side wall of the detection box 5. The output shaft of the detection driving member 7 penetrates through the side wall of the detection box 5 and is fixedly connected with a threaded rod 71. One end of the threaded rod 71 away from the detection driving member 7 is rotatably connected to the inner wall of the detection box 5 through a bearing 73. An installation block 72 is threadedly connected to the threaded rod 71. A moving driving member 74 is fixedly connected to the bottom of the installation block 72. The output shaft of the moving driving member 74 is fixedly connected with an electronic micrometer 75, which is used for sliding contact with the surface of the aluminum rod. It should be noted that the detection driving member 7 can be a motor; the moving driving member 74 can be a cylinder; the electronic micrometer 75 is a prior art device, which is used to convert the detection data on the surface of the aluminum rod into digital signals, and will not be elaborated too much in this application text.

[0028] Reference Figure 5 and Figure 6 As shown in the figure, the detection driving member 7 drives the threaded rod 71 to rotate through the rotation of the output shaft. The threaded rod 71 indirectly drives the installation block 72 to move horizontally. The moving driving member 74 is vertically arranged between the inner top surface of the detection box 5 and its output shaft is downward. The moving driving member 74 drives the electronic micrometer 75 to move in the vertical direction through the expansion and contraction of the output end until the head of the electronic micrometer 75 contacts the surface of the aluminum rod. The electronic micrometer 75 is electrically connected to the controller 12. The electronic micrometer 75 is used to convert the detection data into digital signals and send them to the controller 12. The controller 12 is used to receive the detection values transmitted back by the electronic micrometer 75 and compare them with the qualified thresholds built in the controller 12.

[0029] The fixing mechanism includes a clamping driving member 8, which is fixedly connected to the side wall of the detection box 5. The output shaft of the clamping driving member 8 penetrates through the side wall of the detection box 5 and is fixedly connected with a detection clamping disc 81, which is used for clamping the aluminum rod to be detected.

[0030] It should be noted that the clamping driving member 8 can be a motor, and the detection clamping disc 81 is a pneumatic chuck (such as a three-jaw chuck), which will not be elaborated too much in this application text.

[0031] Reference Figure 5 and Figure 6 As shown in the figure, the clamping driving member 8 drives the detection clamping disc 81 fixedly connected thereto to rotate through the rotation of the output shaft, indirectly driving the aluminum rod to be detected to rotate, so that the detection data on the surface of the aluminum rod is more comprehensive.

[0032] The detection clamping plate 81 clamps the polished aluminum rod. The rotation of the output shaft of the detection driving part 7 drives the threaded rod 71 to rotate. The mounting block 72 is threadedly connected to the threaded rod 71. The rotation of the threaded rod 71 indirectly drives the mounting block 72 to move horizontally. The moving driving part 74 drives the electronic micrometer 75 to move vertically downward through the expansion and contraction of its output end. When the head of the electronic micrometer 75 contacts the surface of the aluminum rod and maintains this state for 2 s, a stable contact is formed between the head of the electronic micrometer 75 and the surface of the aluminum rod. The moving driving part 74 is turned off, and the detection driving part 7 is started to indirectly drive the electronic micrometer 75 to move horizontally, and the detection data is converted into a digital signal and sent to the controller 12. The controller 12 compares the received detection data with the smoothness qualified threshold built in it; If the data detected by the electronic micrometer 75 when it contacts the aluminum rod is qualified compared with the smoothness qualified threshold built in the controller 12, the straightness detection of the aluminum rod and the surface defect detection of the aluminum rod are continued; If the data detected by the electronic micrometer 75 when it contacts the aluminum rod is unqualified compared with the smoothness qualified threshold built in the controller 12, it can be conveyed to the waste area (not shown in the figure) by the robotic arm 11.

[0033] A limiting groove 51 is opened on the inner top surface of the detection box 5. A limiting block 721 is fixedly connected to the top of the mounting block 72. The limiting block 721 is slidably connected to the limiting groove 51.

[0034] Reference Figure 5 The limiting block 721 is slidably connected to the limiting groove 51, preventing the mounting block 72 from rotating when moving horizontally under the action of the threaded rod 71.

[0035] The straightness detection unit includes a fixed seat 10. The fixed seat 10 is fixedly connected to the inner wall of the detection box 5. The fixed seat 10 is sleeved outside the detection clamping plate 81. The inner wall of the fixed seat 10 is in sliding contact with the outer wall of the detection clamping plate 81. A connecting rod 108 is fixedly connected to the fixed seat 10. A fixed ring 101 is fixedly connected to the end of the connecting rod 108 away from the fixed seat 10. A laser emitter 107 is fixedly connected to the detection clamping plate 81. A laser receiver 109 is fixedly connected to the surface of the fixed ring 101 facing the laser emitter 107.

[0036] Four groups of laser emitters 107 are arranged on the detection clamping plate 81. The four groups of laser emitters 107 are evenly distributed in an array along the axis of the detection clamping plate 81. Four groups of laser receivers 109 are also arranged on the fixed ring 101 and their positions correspond to the positions of the laser emitters 107. By using multiple groups of laser emitters 107 and laser receivers 109, the contingency caused by the detection of a single laser emitter 107 and laser receiver 109 is prevented, and the result of the straightness detection of the aluminum rod can be made more accurate.

[0037] Reference Figure 5 、 Figure 6 、 Figure 7 and Figure 8 Figure 8 , the clamping driving member 8 drives the detection clamping disc 81 to rotate through the rotation of the output shaft, emits laser through the laser emitter 107, and drives the polished aluminum rod to rotate through the rotation of the detection clamping disc 81. The laser receiver 109 fixedly connected to the fixed ring 101 is used to receive the laser emitted by the laser emitter 107; If the laser receiver 109 can always receive the laser emitted by the laser emitter 107 during the 360° rotation of the aluminum rod, the straightness of the aluminum rod is qualified; if there is a phenomenon that the laser receiver 109 cannot receive the laser emitted by the laser emitter 107 during the 360° rotation of the aluminum rod, the straightness of the aluminum rod is unqualified.

[0038] A straightening assembly is arranged inside the detection box 5. The straightening assembly includes a first straightening driving member 9. The first straightening driving member 9 is fixedly connected to the side wall of the detection box 5. The output end of the first straightening driving member 9 is fixedly connected with a vertical plate 91. A second straightening driving member 92 is fixedly connected to the vertical plate 91. The output directions of the first straightening driving member 9 and the second straightening driving member 92 are orthogonally arranged. The output end of the second straightening driving member 92 is fixedly connected with a straightening seat 93.

[0039] Two groups of straightening assemblies are symmetrically arranged inside the detection box 5.

[0040] It should be noted that the first straightening driving member 9 and the second straightening driving member 92 can be cylinders.

[0041] Reference Figure 5 and Figure 7 Figure 7 , the axial center heights of the first straightening driving member 9 and the second straightening driving member 92 on both sides of the detection box 5 are the same as the axial center height of the detection clamping disc 81. The first straightening driving member 9 drives the second straightening driving member 92 to move horizontally through the expansion and contraction of the output end. The second straightening driving member 92 drives the straightening seat 93 to abut against the aluminum rod to be straightened through the expansion and contraction of the output end, and straightens the bent part of the aluminum rod through the extrusion of the straightening seat 93 on the other side; When the straightness of the aluminum rod is detected to be unqualified by using the laser beam alignment technology during the above process, at this time, the controller 12 triggers the straightening assembly to perform a straightening operation on the position where the straightness of the aluminum rod is unqualified; if the straightness of the aluminum rod is qualified after straightening, the straightened aluminum rod can be conveyed to the blanking conveyor belt 23 by the robotic arm 11; if the straightness of the aluminum rod is unqualified after straightening, it is conveyed to the waste area (not shown in the figure) by the robotic arm 11.

[0042] The surface defect detection unit includes a cross plate 102, the cross plate 102 is fixedly connected to the mounting block 72, a vertical rod 103 is fixedly connected to the bottom of the cross plate 102, a visual defect detection ring 106 is fixedly connected to the end of the vertical rod 103 away from the cross plate 102, the visual defect detection ring 106 is slidably arranged outside the connecting rod 108, an LED lamp 104 is fixedly connected to the inner wall of the visual defect detection ring 106, an industrial camera 105 is fixedly connected to the inner wall of the visual defect detection ring 106, six groups of industrial cameras 105 are evenly arranged along the axis of the visual defect detection ring 106, each group of industrial cameras 105 covers a 60° circumferential area, and the industrial cameras 105 are electrically connected to the controller 12.

[0043] Reference Figure 5 and Figure 8 , as the threaded rod 71 rotates, the mounting block 72 moves, indirectly driving the visual defect detection ring 106 to move synchronously with the electronic micrometer 75. When the aluminum rod rotates, the six groups of industrial cameras 105 are triggered to perform detection work synchronously. Then, the six groups of industrial cameras 105 splice the 360° surface image of the aluminum rod and send it to the controller 12. The controller 12 is used to receive the 360° surface image of the aluminum rod and compare it with the standard image built in it. The preset qualified standard value of the surface defect length in the controller 12 is d, and the preset qualified standard value of the surface slight oxidation spot area is m; When the length of the surface defect > d, it is marked by a coding machine (prior art, not shown in the figure), and the speed is reduced for manual re-inspection. After passing the inspection, the robotic arm 11 is used to transport it to the blanking conveyor belt 23 for subsequent operations; if the inspection is unqualified, the robotic arm 11 is used to transport it to the waste area (not shown in the figure).

[0044] When the area of the slight oxidation spot on the aluminum rod surface < m, the position is marked by a coding machine (prior art, not shown in the figure). The controller 12 controls the robotic arm 11 to take out the aluminum rod from the detection box 5 through the built-in program, and then controls the robotic arm 11 to put the aluminum rod back into the grinding box 6 for secondary grinding through the internal program of the controller 12. After grinding, if the oxidation spot is completely removed, the robotic arm 11 is used to transport it to the blanking conveyor belt 23 for subsequent operations; if the oxidation spot is still not completely removed, the robotic arm 11 is used to transport it to the waste area (not shown in the figure).

[0045] The loading conveyor belt 21 is arranged on one side of the workbench 1 and is used to transport the aluminum rod to be transported into the workbench 1; the return conveyor belt 22 is arranged on the same side of the loading conveyor belt 21 on the workbench 1 and is used to return the unqualified aluminum rod to the loading conveyor belt 21; the blanking conveyor belt 23 is arranged opposite to the loading conveyor belt 21 and is used to transport the qualified aluminum rod to the next process.

[0046] A heating box 3 is provided on the loading conveyor belt 21.

[0047] It should be noted that the heating box 3 is a prior art, which uses induction heating (electromagnetic eddy current heating) to heat the aluminum rod, and will not be elaborated too much in this application text.

[0048] A cooling box 4 is provided on the loading conveyor belt 21 for cooling the heated aluminum rod. The cooling box 4 is penetrated through the loading conveyor belt 21. An air cavity 41 is opened inside the cooling box 4. A blower 42 is fixedly connected to the side wall of the cooling box 4. The air outlet end of the blower 42 is hermetically connected to the air cavity 41 through a pipeline. A plurality of ventilation holes 43 are evenly arranged in an array on the air cavity 41. An air outlet nozzle 45 is fixedly connected to each ventilation hole 43. A valve 44 is arranged inside the ventilation hole 43.

[0049] It should be noted that the blower 42 is a prior art, and will not be elaborated too much in this application text.

[0050] Reference Figure 1 and Figure 9 , the blower 42 conveys cold air to the air cavity 41 inside the cooling box 4 through its air outlet end. Through the action of the blower 42, the cold air in the air cavity 41 will be blown from the inside of the air cavity 41 to the outside of the air cavity 41 through the guiding action of the ventilation holes 43 and the air outlet nozzles 45. The cooling box 4 is penetrated through the loading conveyor belt 21. The cold air blown out from the air cavity 41 blows towards the aluminum rod taken out from the heating box 3. The cold air blowing towards the aluminum rod will take away the heat on the aluminum rod, thus playing a role in cooling the aluminum rod. The valve 44 is an electromagnetic valve and is electrically connected to the controller 12, and is used to control the opening and closing of the ventilation holes 43. By controlling the opening and closing of the valve 44, the cooling time of the aluminum rod can be adjusted.

[0051] In this application, by setting a smoothness detection unit, a straightness detection unit, and a surface defect detection unit in the aluminum rod conveying system, the aluminum rod can be detected during the conveying process of the aluminum rod. At the same time, the straightening assembly arranged in the detection box 5 can further reduce the unqualified rate of the aluminum rod, thereby ensuring a higher qualified rate of the aluminum rod conveying, reducing the rework frequency, and further improving the conveying efficiency of the qualified aluminum rod.

[0052] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
