Description

Technical Field

[0001] The invention relates to the field of aluminum rod defect detection equipment, and in particular to a defect detection equipment and a detection process for recycled aluminum rod production. Background Art

[0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and scrap aluminum alloy materials or aluminum-containing scrap. It is an important source of metallic aluminum. The main raw material for smelting recycled aluminum is industrial depreciated scrap aluminum parts. In the existing process, scrap aluminum is usually used to prepare recycled aluminum, and then recycled aluminum is used to prepare aluminum rods. In order to supervise and test the recycling equipment and recycling process during the production process, it is usually necessary to add an aluminum rod defect detection equipment and detection process to the production process. However, traditional detection equipment usually adopts mechanical detection means, and the aluminum rod is easily damaged during the detection process. When the aluminum rod is produced, it often has a certain temperature and a high expansion coefficient, and the detection result is less accurate. When the detection is carried out in the post-process, due to the contact and influence of the pre-process, the detection results obtained often cannot well reflect the defects of the recycling equipment and the recycling process.

[0006] Preferably, connecting frames are provided on both sides of the middle part of the first detection part, and the end of the connecting frame close to the fixed ring is fixedly connected to a joint, and the end of the fixed ring away from the rotating frame is rotatably connected to the inside of the bayonet, and the bayonet is arranged on the inner side of the end of the joint close to the fixed ring.

[0007] Preferably, a bevel gear ring 2 is installed at one end of the outer periphery of the connecting frame close to the bevel gear ring 1, and the bottoms of the bevel gear ring 1 and the bevel gear ring 2 are meshed and connected to the two sides of the top of the bevel gear. The bevel gear on one side is rotatably connected to the upper part of the outer periphery of the fixed shaft, and the bevel gear on the other side is fixedly connected to the outer periphery of the top of the reduction motor driving end.

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

[0009] Preferably, one end of the connecting frame away from the fixing ring one is fixedly connected to the fixing ring two, the outer periphery of the fixing ring two is provided with evenly distributed installation bins, the bottom of the installation bins is fixedly connected to air jets, and the air jets penetrate the fixing tube.

[0010] Preferably, fan blades are provided inside the installation bin, a rotating shaft is fixedly connected to the middle of the fan blades, the ends of the rotating shaft pass through the cover, the rotating shaft and the cover are rotatably connected, and the cover is installed at the end of the installation bin.

[0011] Preferably, the outer periphery of one end of the rotating shaft away from the fan blades is fixedly connected with a side tooth ring, and the side tooth rings are arranged on both sides of the mounting ring. Both sides of the outer periphery of the mounting ring are fixedly connected with evenly distributed meshing teeth, and the mounting rings are meshed with the side tooth rings through the meshing teeth.

[0012] Preferably, the mounting rings are fixedly connected on both sides of the middle part of the first detection part, the mounting rings are sleeved on the middle part of the outer circumference of the fixed cylinder, the fixed cylinder is rotatably connected to the mounting ring and the first detection part, and evenly distributed air vents are opened on both sides of the middle part of the outer circumference of the first detection part.

[0013] Preferably, a defect detection process for recycled aluminum rod production includes the following detection steps: S1. In actual use, people fix bolts to install the aluminum rod defect detector to the outlet end of the recycled aluminum rod extruder to achieve the installation of the aluminum rod defect detector, and then pull the regenerated aluminum rod body to make it 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 peripheral defect detection of the aluminum rod body; S2. During the detection process, the detection components in the first detection unit and the second detection unit both use laser detectors to detect peripheral defects of the aluminum rod body. The laser detector emits a laser beam to illuminate the surface of the aluminum rod body, detects the intensity, angle and other parameters of the reflected light to determine the surface defects of the aluminum rod body, and synchronously transmits the detection data to the receiving device for people to view; S3. During the detection, the reduction motor is started first. The work of the reduction motor drives the bevel gear to rotate. The bevel gear drives the bevel gear ring 1 and the bevel gear ring 2 on one side to rotate synchronously in the opposite direction. The bevel gear ring 2 uses the joint and the connecting frame to drive the fixed cylinder to rotate. When the fixed cylinder rotates, the side gear ring on the fixed cylinder will be relatively displaced with the meshing teeth on the mounting ring to achieve continuous meshing, which will cause the side gear ring to be driven to rotate. When the side gear ring rotates, the shaft will drive the fan blades to rotate. When the fan blades rotate, they will stir the surrounding air to form an airflow, which will be ejected from the air jet port to achieve cooling and cleaning of the aluminum rod body. Cooling and cleaning the aluminum rod body before detection can effectively avoid the influence of dust on the detection results of the laser detector. S4, the bevel gear ring 1 drives the fixed ring 1 and the rotating frame 1 to rotate, and the laser detectors inside the fixed ring 1 and the rotating frame 1 realize the first peripheral defect detection of the aluminum rod body, so that the rotating frame 1 makes the laser detectors distributed in a spiral shape to realize the all-round detection of the outer periphery of the aluminum rod body, and at the same time, the laser detectors are staggered and separated in the space coordinates to avoid the situation where the laser encounters the defect and causes the reflected laser to affect the detection of other laser detectors; S5. A fixed second detection component is installed inside the second detection part. The second detection component realizes secondary detection of defects on the periphery of the aluminum rod body. At this time, the aluminum rod body has been cooled and cleaned on both sides to achieve a detection result of the second detection component that is closer to the actual data, thereby realizing the correction of the first detection component in the first detection part, and realizing the mutual coordination and correction of the two detection components.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention can realize the peripheral defect detection of the aluminum rod main body through the first detection part and the second detection part inside the aluminum rod defect detector, and realizes the first-time defect detection of the recycled aluminum rod main body by directly installing the aluminum rod defect detector at the exit end of the production equipment, thereby avoiding the influencing factors of subsequent guiding, straightening and shearing processes on the aluminum rod main body, so that the aluminum rod defect detector can detect the peripheral defects of the aluminum rod main body produced by the recycling equipment and the recycling process in the first time, and can directly avoid most of the external influences on the detection results, and perform source detection, so that the detection results can be more efficient and accurate, which is beneficial to the supervision and analysis of the recycling equipment and the recycling process.

[0015] During the detection process, the detection components in the first detection part and the second detection part both use laser detectors to perform peripheral defect detection on the aluminum rod body. The laser detector can emit a laser beam to irradiate the surface of the aluminum rod body, and judge the surface defects of the aluminum rod body by detecting parameters such as the intensity and angle of the reflected light. The detection data can be synchronously transmitted to the receiving device for people to view. By using laser detectors for defect detection, the aluminum rod body does not need to undergo mechanical contact during the detection process, thereby avoiding damage to the aluminum rod body due to the detection process, which is beneficial to actual use.

[0016] During detection, when the side gear ring rotates, it will drive the fan blades to rotate through the shaft. When the fan blades rotate, they will stir the surrounding air to form an airflow, which will be ejected through the air jet port to achieve cooling and cleaning of the aluminum rod body. By cooling and cleaning the aluminum rod body before testing, the influence of dust and other factors on the detection results of the laser detector can be effectively avoided. At the same time, by quickly cooling the aluminum rod body, the aluminum rod body can reach normal temperature faster, and its expansion coefficient can be reduced to a normal range, avoiding the error value of the detection at this time. At the same time, it can effectively avoid the heat radiation on the aluminum rod body that may interfere with the laser signal, making the signal received by the detector complicated and difficult to accurately analyze and process, thereby reducing the detection accuracy, which is beneficial to actual use.

[0017] The bevel gear ring 1 can drive the fixed ring 1 and the rotating frame 1 to rotate, and the laser detectors inside the fixed ring 1 and the rotating frame 1 can realize the first peripheral defect detection of the aluminum rod body. The rotating frame 1 can make the laser detectors distributed in a spiral shape, thereby realizing all-round detection of the periphery of the aluminum rod body. At the same time, by staggering the laser detectors in the spatial coordinates, it is possible to avoid the situation in which the laser encounters the defect during actual detection, causing the reflected laser to affect the detection of other laser detectors.

[0018] By rotating the first detection component, each laser detector can realize joint full-circle detection of the aluminum rod body during the detection of the aluminum rod body, which is beneficial to practical use. At the same time, a fixed second detection component is installed inside the second detection part, and the second detection component can realize secondary detection of peripheral defects of the aluminum rod body. At this time, the aluminum rod body has been cooled and cleaned on both sides, so that the detection result of the second detection component can be closer to the actual data, and the first detection component in the first detection part can be calibrated. Through the mutual cooperation and correction of the two detection components, the final detection result can be made more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Among them, a defect detection process for the production of recycled aluminum rods is applied to a defect detection device for the production of recycled aluminum rods according to any one of claims 1 to 9, and is characterized in that it includes the following detection steps: S1. In actual use, people can install the aluminum rod defect detector 1 to the outlet end of the recycled aluminum rod extruder by fixing bolts to realize the installation of the aluminum rod defect detector 1, and then pull the regenerated aluminum rod body 104 to pass through the aluminum rod defect detector 1.

The rotating frame 118 can make the laser detectors 106 spirally distributed, so as to realize the all-round detection of the periphery of the aluminum rod body 104. At the same time, the laser detectors 106 are staggered and separated in the space coordinates to avoid the situation that the laser encounters the defect and the reflected laser affects the detection of other laser detectors 106; S5. A fixed second detection component is installed inside the second detection part 101. The second detection component can realize secondary detection of peripheral defects of the aluminum rod body 104.

[0026] Working principle: In actual use, people can install the aluminum rod defect detector 1 to the outlet end of the recycled aluminum rod extruder by fixing bolts to realize the installation of the aluminum rod defect detector 1, and then pull the regenerated aluminum rod main body 104 to make it pass through the aluminum rod defect detector 1. When the aluminum rod main body 104 passes through the aluminum rod defect detector 1, the peripheral defect detection of the aluminum rod main body 104 can be realized through the first detection part 102 and the second detection part 101 inside the aluminum rod defect detector 1. 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 main body 104 can be realized in the first time, so that the influencing factors of the subsequent guiding, straightening and shearing processes on the aluminum rod main body 104 can be avoided, so that the aluminum rod defect detector The detector 1 can detect the peripheral defects of the aluminum rod body 104 produced by the regeneration equipment and the regeneration process in the first time, can directly avoid most of the external influences on the detection results, and perform source detection, so that the detection results can be more efficient and accurate, which is conducive to the supervision and analysis of the regeneration equipment and the regeneration process. During the detection process, the detection components in the first detection part 102 and the second detection part 101 both use laser detectors 106 to detect peripheral defects of the aluminum rod body 104.

By using the laser detector 106 for defect detection, the aluminum rod body 104 does not need to be subjected to mechanical contact during the detection process, thereby preventing the aluminum rod body 104 from being damaged during the detection process, which is beneficial to actual use. During the detection, the reduction motor 120 is started first, and the bevel gear 122 can be driven to rotate through the operation of the reduction motor 120. The bevel gear 122 can drive the bevel gear ring 1 119 on one side to rotate synchronously with the bevel gear ring 2 110 in the opposite direction. The bevel gear ring 2 110 can use the joint 117 and the connecting frame 115 to drive the fixed cylinder 108 to rotate. When the fixed cylinder 108 rotates, the side gear ring 123 on the fixed cylinder 108 will perform relative displacement with the meshing teeth 127 on the mounting ring 124 to achieve continuous meshing, thereby causing The side gear ring 123 will be driven to rotate, and when the side gear 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, and the airflow will be ejected through the air jet 114 to achieve cooling and cleaning of the aluminum rod body 104. By cooling and cleaning the aluminum rod body 104 before testing, the influence of dust and the like on the detection result of the laser detector 106 can be effectively avoided. At the same time, by quickly cooling the aluminum rod body 104, the aluminum rod body 104 can reach normal temperature faster, so that its expansion coefficient is reduced to a normal range, avoiding the error value of the detection at this time. At the same time, it can effectively avoid that the heat radiation on the aluminum rod body 104 may interfere with the laser signal, making the signal received by the detector complicated.It is difficult to accurately analyze and process, thereby reducing the detection accuracy. It is beneficial to actual use. The bevel gear ring 119 can drive the fixed ring 111 and the rotating frame 118 to rotate. The laser detector 106 on the inner side of the fixed ring 111 and the rotating frame 118 can realize the first peripheral defect detection of the aluminum rod body 104. The rotating frame 118 can make the laser detector 106 spirally distributed, thereby realizing all-round detection of the periphery of the aluminum rod body 104. At the same time, the laser detector 106 is staggered and separated in the space coordinates, so that in actual detection, it can be avoided that the laser encounters the defect, resulting in the reflected laser affecting the detection of other laser detectors 106. At the same time, By rotating the first detection component, each laser detector 106 can realize the joint full-circle detection of the aluminum rod body 104 during the detection of the aluminum rod body 104, which is beneficial to practical use. At the same time, a fixed second detection component is installed inside the second detection part 101, and the second detection component can realize the secondary detection of the 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 that the detection result of the second detection component can be closer to the actual data, and the first detection component in the first detection part 102 can be corrected. Through the mutual cooperation and correction of the two detection components, the final detection result can be made more accurate.

10. A defect detection process for recycled aluminum rod production, applied to a defect detection device for recycled aluminum rod production as claimed in any one of claims 1 to 9, characterized in that: The following detection steps are included: S1. In actual use, people fix bolts to install the aluminum rod defect detector (1) to the outlet end of the recycled aluminum rod extruder to achieve 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) achieve the peripheral defect detection of the aluminum rod body (104); S2. During the detection process, the detection components in the first detection unit (102) and the second detection unit (101) both use a laser detector (106) to detect peripheral defects of the aluminum rod body (104). The laser detector (106) emits a laser beam to illuminate the surface of the aluminum rod body (104), detects parameters such as the intensity and angle of the reflected light to determine the surface defects of the aluminum rod body (104), and synchronously transmits the detection data to a receiving device for easy viewing by people; S3. During the inspection, the reduction motor (120) is first started. The reduction motor (120) drives the bevel gear (122) to rotate. The bevel gear (122) drives the bevel gear ring 1 (119) on one side to rotate synchronously with the bevel gear ring 2 (110) in the opposite direction. The bevel gear ring 2 (110) drives the fixed cylinder (108) to rotate by means of the joint (117) and the connecting frame (115). When the fixed cylinder (108) rotates, the side gear ring (123) on the fixed cylinder (108) engages with the meshing gear on the mounting ring (124). (127) performs relative displacement to achieve continuous meshing, which causes the side gear ring (123) to be driven to rotate. When the side gear ring (123) rotates, the shaft (129) drives the fan blade (128) to rotate. When the fan blade (128) rotates, it stirs the surrounding air to form an airflow, and the airflow is ejected from the air jet (114) to achieve cooling and cleaning of the aluminum rod body (104). The aluminum rod body (104) is cooled and cleaned before detection, which effectively avoids the influence of dust on the detection result of the laser detector (106); S4, the bevel gear ring 1 (119) drives the fixed ring 1 (111) and the rotating frame 1 (118) to rotate, and the laser detectors (106) inside the fixed ring 1 (111) and the rotating frame 1 (118) realize the first peripheral defect detection of the aluminum rod body (104), so that the rotating frame 1 (118) makes the laser detectors (106) distributed in a spiral shape to realize all-round detection of the periphery of the aluminum rod body (104), and at the same time, the laser detectors (106) are staggered and separated in the spatial coordinates to prevent the laser from encountering the defect, resulting in the reflected laser affecting the detection of other laser detectors (106); S5. A fixed second detection component is installed inside the second detection part (101). The second detection component realizes secondary detection of defects on the periphery of the aluminum rod body (104). At this time, the aluminum rod body (104) has been cooled and cleaned on both sides, so that the detection result of the second detection component is closer to the actual data, and the first detection component in the first detection part (102) is calibrated, so that the two detection components can cooperate and calibrate with each other.
