Description

Technical Field

[0001] This invention relates to the field of aluminum rod defect detection equipment, and more particularly to a defect detection equipment and detection process for recycled aluminum rod production. Background Technology

[0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and aluminum alloy materials or aluminum-containing waste. It is an important source of metallic aluminum. The main raw material for smelting recycled aluminum is industrially depreciated scrap aluminum parts. In existing processes, scrap aluminum is usually used to produce recycled aluminum, which is then used to produce aluminum rods. In order to monitor and test the recycling equipment and recycling process during production, it is usually necessary to add an aluminum rod defect detection device and detection process to the production process. However, traditional detection equipment usually uses mechanical detection methods, and aluminum rods are easily damaged during the detection process. Moreover, aluminum rods often have a certain temperature when they are produced, and their expansion coefficient is relatively high, resulting in less accurate detection results. When detection is carried out in subsequent processes, the detection results obtained due to the contact and influence of the previous processes often cannot reflect the defects of the recycling equipment and recycling process well. Therefore, we propose a defect detection device and detection process for recycled aluminum rod production to solve the above-mentioned problems. Summary of the Invention

[0006] Preferably, a connecting frame is provided on both sides of the middle part of the first detection unit. A connector is fixedly connected to the end of the connecting frame near the first fixing ring. The end of the first fixing ring away from the first rotating frame is rotatably connected to the inside of the bayonet. The bayonet is located on the inner side of the end of the connector near the first fixing ring.

[0007] Preferably, a second bevel gear ring is installed on the outer periphery of the connecting frame near the first bevel gear ring. The bottoms of the first bevel gear ring and the second bevel gear ring are meshed and connected to the top two sides of the bevel gear. One side of the bevel gear is rotatably connected to the upper part of the outer periphery of the fixed shaft, and the other side of the bevel gear is fixedly connected to the top outer periphery of the drive end of the geared motor.

[0008] Preferably, the fixed shaft is fixedly connected to the middle of one side of the top of the fixed chamber, the reduction motor is installed in the middle of the other side of the top of the fixed chamber, and the fixed chamber is fixedly connected to the middle of the bottom of the first detection unit.

[0009] Preferably, each end of the connecting frame away from the fixing ring is fixedly connected to a fixing cylinder, and each fixing cylinder is provided with evenly distributed installation chambers on its outer periphery. Each installation chamber is fixedly connected to an air jet port, and each air jet port penetrates the fixing cylinder.

[0010] Preferably, each of the installation chambers is equipped with fan blades, each fan blade is fixedly connected to a rotating shaft in the middle, each rotating shaft has a cover penetrating through its end, the rotating shaft and the cover are rotatably connected, and the cover is installed at the end of the installation chamber.

[0011] Preferably, a side toothed ring is fixedly connected to the outer periphery of the end of the rotating shaft away from the fan blade. The side toothed rings are all arranged on both sides of the mounting ring. The outer periphery of the mounting ring is fixedly connected with uniformly distributed meshing teeth. The mounting ring is connected to the side toothed rings through meshing teeth.

[0012] Preferably, the mounting rings are all fixedly connected to both sides of the inner middle of the first detection part, the mounting rings are all sleeved on the middle of the outer periphery of the fixed cylinder, the fixed cylinder is rotatably connected to the mounting rings and the first detection part, and the two sides of the middle of the outer periphery of the first detection part are provided with evenly distributed air vents.

[0013] Preferably, a defect detection process for the production of recycled aluminum rods includes the following detection steps:

[0014] S1. In actual use, the aluminum rod defect detector is installed at the outlet end of the recycled aluminum rod extruder by fixing bolts to realize the installation of the aluminum rod defect detector. Then, the recycled aluminum rod body is pulled to pass through the aluminum rod defect detector. When the aluminum rod body passes through the aluminum rod defect detector, the first detection part and the second detection part inside the aluminum rod defect detector realize the detection of the outer peripheral defects of the aluminum rod body.

[0015] S2. During the inspection process, the inspection components in the first and second inspection departments both use laser detectors to inspect the peripheral defects of the aluminum rod body. The laser detector emits a laser beam to irradiate the surface of the aluminum rod body, and detects the intensity and angle parameters of the reflected light to determine the surface defects of the aluminum rod body. The inspection data is then synchronously transmitted to the receiving device for easy viewing.

[0016] S3. During testing, the reduction motor is started first. The operation of the reduction motor drives the bevel gear to rotate. The bevel gear drives the bevel tooth ring one and bevel tooth ring two on one side to rotate synchronously in opposite directions. The bevel tooth ring two drives the fixed cylinder to rotate through the joint and connecting frame. When the fixed cylinder rotates, the side tooth ring on the fixed cylinder will be relatively displaced with the meshing teeth on the mounting ring to achieve continuous meshing. This will cause the side tooth ring to be driven to rotate. When the side tooth ring rotates, it will drive the fan blade to rotate through the rotating shaft. When the fan blade rotates, it will stir the surrounding air to form an airflow. The airflow will be sprayed out from the jet nozzle to cool and clean the aluminum rod body. By cooling and cleaning the aluminum rod body before testing, the influence of dust on the laser detector test results is effectively avoided.

[0017] S4. The bevel ring drives the fixed ring and the rotating frame to rotate. The laser detectors on the inner side of the fixed ring and the rotating frame realize the first peripheral defect detection of the aluminum rod body. The rotating frame makes the laser detectors spirally distributed to realize all-round detection of the outer periphery of the aluminum rod body. At the same time, the laser detectors are staggered in the spatial coordinate to avoid the situation where the laser encounters the defect and causes the reflected laser to affect the detection of other laser detectors.

[0018] S5. A fixed second detection component is installed inside the second detection unit. The second detection component performs secondary detection of defects on the outer periphery of the aluminum rod body. At this time, the aluminum rod body has been cooled and cleaned on both sides, making the detection results of the second detection component closer to the actual data, realizing the mutual cooperation and correction of the two detection components.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This invention enables the detection of peripheral defects in the aluminum rod body through the first and second detection units inside the aluminum rod defect detector. By directly installing the aluminum rod defect detector at the outlet of the production equipment, it achieves immediate defect detection of the recycled aluminum rod body, thereby avoiding the influence of subsequent guiding, straightening, and shearing processes on the aluminum rod body. This allows the aluminum rod defect detector to detect peripheral defects in the aluminum rod body produced by the recycling equipment and recycling process at the first time, directly avoiding most of the external influence on the detection results, and performing source detection. This makes the detection results more efficient and accurate, which is beneficial for the supervision and analysis of the recycling equipment and recycling process.

[0021] 2. During the inspection process, both the first and second inspection units use laser detectors to detect peripheral defects in the aluminum rod body. The laser detector emits a laser beam to illuminate the surface of the aluminum rod body, and the surface defects are determined by detecting the intensity and angle parameters of the reflected light. The inspection data can be synchronously transmitted to the receiving device for easy viewing. By using laser detectors for defect detection, the aluminum rod body does not need to undergo mechanical contact during the inspection process, avoiding damage to the aluminum rod body due to the inspection process, which is beneficial for practical use.

[0022] 3. During testing, the rotation of the side gear ring drives the fan blades to rotate via the shaft. The rotation of the fan blades stirs the surrounding air, creating an airflow that is ejected through the nozzle. This airflow cools and cleans the aluminum rod body. Cooling and cleaning the aluminum rod body before testing effectively avoids the influence of dust on the laser detector's results. Furthermore, rapid cooling of the aluminum rod body allows it to reach room temperature more quickly, reducing its expansion coefficient to within the normal range and preventing errors in the test. It also effectively prevents interference between thermal radiation from the aluminum rod body and the laser signal, which could complicate the signal received by the detector, making accurate analysis and processing difficult and reducing detection accuracy. This is beneficial for practical use.

[0023] 4. The bevel ring can drive the fixed ring and the rotating frame to rotate. The laser detectors inside the fixed ring and the rotating frame can perform the first peripheral defect detection of the aluminum rod body. By making the rotating frame distribute the laser detectors in a spiral shape, it is possible to achieve all-round detection of the outer periphery of the aluminum rod body. At the same time, by separating the laser detectors in spatial coordinates, it is possible to avoid the situation where the laser encounters a defect and causes the reflected laser to affect the detection of other laser detectors during actual detection.

[0024] 5. By rotating the first detection component, each laser detector can perform a combined full-circle inspection of the aluminum rod body during the inspection process, which is beneficial for practical use. At the same time, a fixed second detection component is installed inside the second detection unit. The second detection component can perform secondary inspection of defects on the outer periphery of the aluminum rod body. At this time, the aluminum rod body has undergone cooling and cleaning on both sides, so the detection results of the second detection component can be closer to the actual data, realizing the calibration of the first detection component in the first detection unit. Through the cooperation and calibration of the two detection components, the final detection results can be more accurate. Attached Figure Description

[0033] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0034] like Figures 1-7The device shown is a defect detection device for recycled aluminum rod production, including an aluminum rod defect detector 1. An aluminum rod body 104 passes through the aluminum rod defect detector 1. The aluminum rod defect detector 1 includes a second detection part 101 and a first detection part 102. One end of the second detection part 101 is fixedly connected to the first detection part 102. The end of the first detection part 102 away from the second detection part 101 is provided with a mounting flange seat 121. The aluminum rod defect detector 1 is installed at the outlet end of the recycled aluminum rod extruder through the mounting flange seat 121. A second detection assembly is provided inside the second detection part 101. The second detection assembly includes a second rotating frame 116. Both ends of the second rotating frame 116 are fixedly connected to a second fixing ring 105. The outer periphery of the second fixing ring 105 is fixedly connected to uniformly distributed fixing blocks 107. The outer periphery of the second fixing ring 105 is fixedly connected to both sides inside the second detection part 101 through the fixing blocks 107. Uniformly distributed laser detectors 106 are installed on the inner sides of the second fixing ring 105 and the second rotating frame 116.

[0035] Furthermore, in specific implementation, the aluminum rod defect detector 1 can be installed at the outlet end of the recycled aluminum rod extruder using fixing bolts, thus completing the installation of the aluminum rod defect detector 1. Afterwards, the recycled aluminum rod body 104 is pulled through the aluminum rod defect detector 1. When the aluminum rod body 104 passes through the aluminum rod defect detector 1, the first detection part 102 and the second detection part 101 inside the aluminum rod defect detector 1 can detect peripheral defects of the aluminum rod body 104. By directly installing the aluminum rod defect detector 1 at the outlet end of the production equipment, the defect detection of the recycled aluminum rod body 104 is achieved at the first moment, thereby avoiding the influence of subsequent guiding, straightening, and shearing processes on the aluminum rod body 104, allowing the aluminum rod defect detector 1 to effectively detect defects. The device can detect peripheral defects of the aluminum rod body 104 produced by the recycling equipment and recycling process in the first instance, directly avoiding most of the external influence on the test results, and conducting source testing. This makes the test results more efficient and accurate, which is beneficial for the supervision and analysis of the recycling equipment and recycling process. At the same time, a fixed second testing component is installed inside the second testing unit 101. The second testing component can realize secondary testing of peripheral defects of the aluminum rod body 104. At this time, the aluminum rod body 104 has been cooled and cleaned on both sides, so the test results of the second testing component can be closer to the actual data, realizing the correction of the first testing component in the first testing unit 102. Through the cooperation and correction of the two testing components, the final test results can be more accurate.

[0036] The first detection unit 102 contains a first detection assembly, which includes a rotating frame 118. Both ends of the rotating frame 118 are fixedly connected to fixing rings 111. Evenly distributed laser detectors 106 are installed inside both the fixing rings 111 and the rotating frame 118. Conical toothed rings 119 are fixedly connected to the outer periphery of the fixing rings 111 on opposite sides. Connecting frames 115 are provided on both sides of the middle section of the first detection unit 102. A connector 117 is fixedly connected to the end of the connecting frame 115 closest to the fixing rings 111. The end of the fixing rings 111 furthest from the rotating frame 118 is rotatably connected to a bayonet 109. The bayonet 109 is... A bevel gear ring 110 is installed on the inner side of the connector 117 near the fixed ring 111. A bevel gear ring 110 is installed on the outer periphery of the connecting frame 115 near the bevel gear ring 119. The bottom of the bevel gear ring 119 and the bevel gear ring 110 are meshed and connected to the top two sides of the bevel gear 122. One side of the bevel gear 122 is rotatably connected to the upper part of the outer periphery of the fixed shaft 113. The other side of the bevel gear 122 is fixedly connected to the top outer periphery of the drive end of the reduction motor 120. The fixed shaft 113 is fixedly connected to the middle part of one side of the top of the fixed chamber 112. The reduction motor 120 is installed in the middle part of the other side of the top of the fixed chamber 112. The fixed chamber 112 is fixedly connected to the middle part of the bottom end of the first detection part 102.

[0037] Furthermore, in specific implementation, during the inspection process, both the first inspection unit 102 and the second inspection unit 101 employ laser detectors 106 to detect peripheral defects in the aluminum rod body 104. The laser detector 106 emits a laser beam to irradiate the surface of the aluminum rod body 104, and the intensity and angle parameters of the reflected light are used to determine surface defects. The inspection data is also synchronously transmitted to a receiving device for easy viewing. Using laser detectors 106 for defect detection avoids mechanical contact with the aluminum rod body 104 during inspection, preventing damage and facilitating practical use. The bevel ring 119 drives the fixed ring 111 and the rotating frame 118 to rotate. The first peripheral defect detection of the aluminum rod body 104 can be achieved by the laser detector 106 inside the fixed ring 111 and the rotating frame 118. By making the rotating frame 118 so that the laser detector 106 is distributed in a spiral shape, all-round detection of the outer periphery of the aluminum rod body 104 can be achieved. At the same time, by separating the laser detector 106 in a staggered manner in spatial coordinates, it is possible to avoid the situation where the laser encounters a defect and causes the reflected laser to affect the detection of other laser detectors 106 during actual detection. In addition, by rotating the first detection component, each laser detector 106 can achieve joint full-circle detection of the aluminum rod body 104 during the detection process, which is beneficial to practical use.

[0038] In this configuration, a fixed cylinder 108 is fixedly connected to the end of the connecting frame 115 away from the fixed ring 111. Evenly distributed mounting chambers 125 are provided around the outer periphery of each fixed cylinder 108. An air nozzle 114 is fixedly connected to the bottom of each mounting chamber 125, penetrating the fixed cylinder 108. Fan blades 128 are installed inside each mounting chamber 125. A rotating shaft 129 is fixedly connected to the middle of each fan blade 128. The end of each rotating shaft 129 penetrates a cover 126, and the rotating shaft 129 and the cover 126 are rotatably connected. The cover 126 is installed at the end of each mounting chamber 125, with the rotating shaft 129 away from the fan blades 128. A side toothed ring 123 is fixedly connected to the outer periphery of one end of the mounting ring 124. The side toothed ring 123 is set on both sides of the mounting ring 124. The mounting ring 124 is fixedly connected to the two sides of the outer periphery of the mounting ring 124 with evenly distributed meshing teeth 127. The mounting ring 124 is connected to the side toothed ring 123 through the meshing teeth 127. The mounting ring 124 is fixedly connected to both sides of the middle part of the first detection part 102. The mounting ring 124 is sleeved on the middle part of the outer periphery of the fixing cylinder 108. The fixing cylinder 108 is rotatably connected to the mounting ring 124 and the first detection part 102. The two sides of the middle part of the outer periphery of the first detection part 102 are provided with evenly distributed vents 103.

[0039] Furthermore, in specific implementation, during testing, the reduction motor 120 is first started. The operation of the reduction motor 120 drives the bevel gear 122 to rotate. The bevel gear 122 drives the first bevel gear ring 119 and the second bevel gear ring 110 on one side to rotate synchronously in opposite directions. The second bevel gear ring 110 drives the fixed cylinder 108 to rotate via the connector 117 and the connecting frame 115. When the fixed cylinder 108 rotates, the side gear ring 123 on the fixed cylinder 108 will be relatively displaced with the meshing teeth 127 on the mounting ring 124 to achieve continuous meshing. This causes the side gear ring 123 to be driven to rotate. When the side gear ring 123 rotates, it drives the fan blade 128 to rotate via the rotating shaft 129. When the fan blade 128 rotates, it stirs up the surrounding air to form an airflow, which is then ejected through the nozzle 114 to cool and clean the aluminum rod body 104. By cooling and cleaning the aluminum rod body 104 before testing, the influence of dust on the detection results of the laser detector 106 can be effectively avoided. At the same time, the rapid cooling of the aluminum rod body 104 allows it to reach room temperature more quickly, reducing its expansion coefficient to the normal range and avoiding detection errors. It also effectively prevents the thermal radiation from the aluminum rod body 104 from interfering with the laser signal, which could complicate the signal received by the detector, making it difficult to analyze and process accurately and thus reducing the detection accuracy. This is beneficial for practical use.

[0040] One defect detection process for the production of recycled aluminum rods includes the following detection steps:

[0041] S1. In actual use, the aluminum rod defect detector 1 is installed at the outlet end of the recycled aluminum rod extruder by fixing bolts to realize the installation of the aluminum rod defect detector 1. Then, the recycled aluminum rod body 104 is pulled to pass through the aluminum rod defect detector 1. When the aluminum rod body 104 passes through the aluminum rod defect detector 1, the first detection part 102 and the second detection part 101 inside the aluminum rod defect detector 1 realize the detection of defects on the outer periphery of the aluminum rod body 104.

[0042] S2. During the inspection process, the inspection components in the first inspection unit 102 and the second inspection unit 101 both use laser detectors 106 to inspect the peripheral defects of the aluminum rod body 104. The laser detectors 106 emit laser beams to irradiate the surface of the aluminum rod body 104, and detect the intensity and angle parameters of the reflected light to determine the surface defects of the aluminum rod body 104. The inspection data is then synchronously transmitted to the receiving device for easy viewing.

[0043] S3. During testing, the reduction motor 120 is started first. The operation of the reduction motor 120 drives the bevel gear 122 to rotate. The bevel gear 122 drives the bevel tooth ring 119 and bevel tooth ring 110 on one side to rotate synchronously in opposite directions. The bevel tooth ring 110 drives the fixed cylinder 108 to rotate through the connector 117 and the connecting frame 115. When the fixed cylinder 108 rotates, the side tooth ring 123 on the fixed cylinder 108 will be relatively displaced with the meshing teeth 127 on the mounting ring 124 to achieve continuous meshing. This will cause the side tooth ring 123 to be driven to rotate. When the side tooth ring 123 rotates, it will drive the fan blade 128 to rotate through the rotating shaft 129. When the fan blade 128 rotates, it will stir the surrounding air to form an airflow. The airflow will be sprayed out from the jet nozzle 114 to cool and clean the aluminum rod body 104. By cooling and cleaning the aluminum rod body 104 before testing, the influence of dust on the detection results of the laser detector 106 is effectively avoided.

[0044] S4. The bevel ring 119 drives the fixed ring 111 and the rotating frame 118 to rotate. The laser detectors 106 on the inner side of the fixed ring 111 and the rotating frame 118 realize the first peripheral defect detection of the aluminum rod body 104. The rotating frame 118 makes the laser detectors 106 spirally distributed, realizing all-round detection of the outer periphery of the aluminum rod body 104. At the same time, the laser detectors 106 are staggered in the spatial coordinate to avoid the situation where the laser encounters the defect and causes the reflected laser to affect the detection of the other laser detectors 106.

[0045] S5. A fixed second detection component is installed inside the second detection unit 101. The second detection component performs secondary detection of defects on the outer periphery of the aluminum rod body 104. At this time, the aluminum rod body 104 has been cooled and cleaned on both sides, making the detection results of the second detection component closer to the actual data, realizing the mutual cooperation and correction of the two detection components.

[0046] Working principle:

[0047] In practical use, the aluminum rod defect detector 1 can be installed at the outlet end of the recycled aluminum rod extruder using fixing bolts. After installation, the recycled aluminum rod body 104 is pulled through the aluminum rod defect detector 1. As the aluminum rod body 104 passes through the detector, the first detection part 102 and the second detection part 101 inside the detector 1 detect peripheral defects in the aluminum rod body 104. By directly installing the aluminum rod defect detector 1 at the outlet end of the production equipment, immediate defect detection of the recycled aluminum rod body 104 is achieved. This avoids the influence of subsequent guiding, straightening, and shearing processes on the aluminum rod body 104, making the aluminum rod defect detection more efficient. The detector 1 can detect peripheral defects of the aluminum rod body 104 produced by the recycling equipment and recycling process in real time. It can directly avoid most of the external influence on the detection results, and perform source detection, making the detection results more efficient and accurate. This is beneficial for the supervision and analysis of the recycling equipment and recycling process. During the detection process, the detection components in the first detection unit 102 and the second detection unit 101 both use laser detectors 106 to detect peripheral defects of the aluminum rod body 104. The laser detector 106 can emit a laser beam to irradiate the surface of the aluminum rod body 104. By detecting the intensity and angle parameters of the reflected light, the surface defects of the aluminum rod body 104 are judged, and the detection data can be synchronously transmitted to the receiving device for easy viewing. By using a laser detector 106 for defect detection, the aluminum rod body 104 can avoid mechanical contact during the detection process, preventing damage to the aluminum rod body 104 due to the detection process, which is beneficial for practical use. During detection, the reduction motor 120 is started first. The operation of the reduction motor 120 drives the bevel gear 122 to rotate. The bevel gear 122 drives the bevel tooth ring 119 and bevel tooth ring 110 on one side to rotate synchronously in opposite directions. The bevel tooth ring 110 drives the fixed cylinder 108 to rotate through the connector 117 and the connecting frame 115. When the fixed cylinder 108 rotates, the side tooth ring 123 on the fixed cylinder 108 will be relatively displaced with the meshing teeth 127 on the mounting ring 124 to achieve continuous meshing, thereby leading to The side gear ring 123 is driven to rotate, and when the side gear ring 123 rotates, it drives the fan blade 128 to rotate via the rotating shaft 129. The fan blade 128 stirs up the surrounding air to form an airflow, which is then ejected through the jet nozzle 114, achieving cooling and cleaning of the aluminum rod body 104. By cooling and cleaning the aluminum rod body 104 before detection, the influence of dust on the detection results of the laser detector 106 can be effectively avoided. At the same time, the rapid cooling of the aluminum rod body 104 allows it to reach room temperature more quickly, reducing its expansion coefficient to a normal range and avoiding detection errors. Furthermore, it effectively prevents thermal radiation from the aluminum rod body 104 from interfering with the laser signal, thus avoiding complex signals received by the detector.To avoid situations where accurate analysis and processing are difficult, thus reducing detection accuracy, this design is beneficial for practical use. The beveled ring 119 drives the fixed ring 111 and the rotating frame 118 to rotate. The laser detectors 106 inside the fixed ring 111 and the rotating frame 118 enable the first peripheral defect detection of the aluminum rod body 104. By arranging the rotating frame 118 in a spiral pattern, the laser detectors 106 can achieve omnidirectional detection of the aluminum rod body 104's outer perimeter. Furthermore, by staggering the laser detectors 106 in spatial coordinates, during actual detection, it avoids situations where a laser encounters a defect, causing reflected laser light to interfere with the detection of other laser detectors 106. By rotating the first detection component, each laser detector 106 can perform a combined full-circle inspection of the aluminum rod body 104 during the inspection process, which is beneficial for practical use. Simultaneously, a fixed second detection component is installed inside the second detection unit 101. This second detection component enables secondary inspection of defects on the outer periphery of the aluminum rod body 104. Since the aluminum rod body 104 has already undergone cooling and cleaning on both sides, the inspection results of the second detection component are closer to the actual data, thus correcting the first detection component in the first detection unit 102. Through the cooperation and correction of the two detection components, the final inspection results are more accurate.
