Description

Technical Field

[0001] This utility model relates to the field of aluminum profile production technology, and in particular to an aluminum profile extrusion machine with infrared temperature sensing. Background Technology

[0002] In the production process of aluminum profiles, extrusion molding is one of the key steps, and the temperature and surface quality of the extruded profiles directly determine the performance of the product, the ease of subsequent processing, and the final product qualification rate. Traditional aluminum profile extrusion presses have many shortcomings in quality inspection: temperature detection mostly relies on manual handheld temperature measuring instruments or single temperature sensors. Due to the large amount of aluminum dust, cooling water vapor, etc. in the workshop environment, the test results are easily interfered with, resulting in insufficient accuracy of temperature data and difficulty in accurately reflecting the true temperature state of the profile. Temperature differences can also cause cold shut defects in aluminum profiles. Relying on manual visual inspection is not only inefficient, but also affected by factors such as the experience and fatigue of the inspectors, resulting in a high rate of missed detections and false detections, making it difficult to guarantee the consistency and reliability of the inspection. Therefore, we need to upgrade and transform the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide an aluminum profile extrusion machine with infrared temperature sensing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: Design an aluminum profile extrusion press with infrared temperature sensing, including an extrusion host, a mounting base, an infrared temperature sensor, a vision inspection module, a protective component, and a control panel. The infrared temperature sensor and the vision inspection module are sequentially mounted on the profile outlet end of the extrusion host through the mounting base. The protective component is connected to the lens part of the infrared temperature sensor. The control panel is located on the side wall of the extrusion host and is electrically connected to the infrared temperature sensor, the vision inspection module, and the protective component respectively. The infrared temperature sensor is used to collect surface temperature data of the extruded aluminum profile in real time. It is equipped with a rain cover on the outside. The vision inspection module includes an industrial camera, a light source assembly, an adjustment bracket and an alarm. The industrial camera is mounted on the mounting base through the adjustment bracket. The light source assembly is arranged around the industrial camera. The alarm is electrically connected to the industrial camera.

[0005] Preferably, the protective component includes a miniature air pump, an air duct, and a jet nozzle. The miniature air pump is connected to the jet nozzle through the air duct. The control panel can receive and display feedback signals from an infrared temperature sensor and a visual detection module.

[0006] Preferably, the mounting base is provided with a slide groove extending along the conveying direction of the aluminum profile, and the bottom of the infrared temperature sensor and the vision inspection module are both provided with sliders adapted to the slide groove, and the sliders are provided with locking bolts for fixing the position.

[0007] Preferably, the rain cover is made of stainless steel, with an arc-shaped top and an outwardly extending baffle at the bottom edge, on which drainage holes are provided.

[0008] Preferably, the alarm includes an audible and visual alarm unit. When the visual inspection module detects a defect on the surface of the aluminum profile, the alarm can emit a continuous audible and visual alarm signal and transmit the defect signal to the control panel.

[0009] Preferably, the air duct is fixed to the outside of the rain cover in a ring structure, and the jet nozzles are installed in a ring array on the outside of the air duct, with multiple sets of jet nozzles tilted toward the infrared temperature sensor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model is equipped with an infrared temperature sensor and a visual inspection module. The infrared temperature sensor detects the temperature of the extruded profile, and the visual inspection module performs visual inspection of the shape of the extruded profile. When the profile has defects or abnormal temperature, the alarm sounds. It can simultaneously detect the discharge temperature and appearance defects of the profile, which makes it easy for operators to detect problems and take intervention measures in time. It is conducive to quickly tracing the source of the problem and steadily improving the product qualification rate.

[0011] 2. This utility model has a protective component installed inside the device. It uses a micro air pump to draw in air, which is then guided through an air duct to the jet head. The jet head blows the air to the infrared temperature sensor lens, forming an air curtain around the lens. This provides dust protection for the infrared temperature sensor lens, preventing contaminants such as aluminum shavings and dust from adhering to the lens and affecting the accuracy of temperature measurement. This ensures the accuracy of temperature detection data. At the same time, the air curtain protection method does not require direct contact with the lens, thus avoiding wear and tear on the lens.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1-4 As shown, this embodiment provides an aluminum profile extrusion press with infrared temperature sensing, including an extrusion host 1, a mounting base 11, an infrared temperature sensor 2, a vision inspection module 3, a protective component 4, and a control panel 5. The profile outlet end of the extrusion host 1 is sequentially equipped with the infrared temperature sensor 2 and the vision inspection module 3 through the mounting base 11. The protective component 4 is connected to the lens part of the infrared temperature sensor 2. The control panel 5 is located on the side wall of the extrusion host 1 and is electrically connected to the infrared temperature sensor 2, the vision inspection module 3, and the protective component 4 respectively. The rain cover 21 is made of stainless steel, with an arc-shaped top and an outwardly extending baffle at the bottom edge, on which drainage holes are provided. In this embodiment, the infrared temperature sensor 2 is used to collect the surface temperature data of the extruded aluminum profile in real time. It is equipped with a rain cover 21. The vision inspection module 3 includes an industrial camera 31, a light source assembly 32, an adjustment bracket 33, and an alarm 34. The industrial camera 31 is mounted on the mounting base 11 via the adjustment bracket 33. The light source assembly 32 surrounds the industrial camera 31. The alarm 34 is electrically connected to the industrial camera 31 and includes an audible and visual alarm unit. When the vision inspection module 3 detects a defect on the surface of the aluminum profile, the alarm 34 can emit a continuous audible and visual alarm signal and simultaneously transmit the defect signal to the control panel 5. The mounting base 11 is provided with a groove extending along the conveying direction of the aluminum profile. Both the bottom of the extrusion module 2 and the visual inspection module 3 are equipped with sliders that fit the chute. The sliders are equipped with locking bolts for fixing the position. The infrared temperature sensor 2 detects the temperature of the extruded profile, and the visual inspection module 3 performs visual inspection of the extruded profile. When the profile has defects or the temperature is abnormal, the alarm 34 sounds an alarm. It can simultaneously detect the discharge temperature and appearance defects of the profile, which makes it easy for operators to detect problems and take intervention measures at the first time, avoid the continuous production of unqualified profiles and avoid batch waste, and also facilitate the rapid tracing of the source of the problem, providing an accurate basis for adjusting the extrusion process parameters, thereby steadily improving the product qualification rate. The integrated design also saves equipment space.

[0017] In this embodiment, the protective component 4 includes a miniature air pump 41, an air duct 42, and a jet nozzle 43. The miniature air pump 41 is connected to the jet nozzle 43 through the air duct 42. The control panel 5 can receive and display feedback signals from the infrared temperature sensor 2 and the visual inspection module 3. The air duct 42 is fixed to the outside of the rain cover 21 in a ring structure. The jet nozzles 43 are installed in a ring array on the outside of the air duct 42. Multiple sets of jet nozzles 43 are tilted towards the infrared temperature sensor 2. The miniature air pump 41 draws air, which is then guided through the air duct 42 to the jet nozzles 43. The gas is then blown to the lens of the infrared temperature sensor 2 through the jet nozzles 43, forming an air curtain outside the lens of the infrared temperature sensor 2. This facilitates dust protection of the lens of the infrared temperature sensor 2, preventing contaminants such as aluminum shavings and dust from adhering to the lens and affecting the temperature measurement accuracy. This ensures the accuracy of the temperature detection data. At the same time, the air curtain protection method does not require direct contact with the lens, so it will not cause wear to the lens and helps to extend the service life of the infrared temperature sensor 2.

[0018] The working principle and process of this utility model are as follows: During use, the aluminum profile extruded by the extrusion host 1 is sent out from the outlet. It first passes through the infrared temperature sensor 2 on the mounting base 11, which collects the surface temperature of the profile. Then the profile passes to the vision inspection module 3. The industrial camera 31 is fixed by the adjustment bracket 33. The light source component 32 provides supplementary lighting to clearly capture the image. The sliding groove of the mounting base 11 facilitates the adjustment of the position of the sensor and the inspection module. The protective component 4 operates synchronously. The micro air pump 41 blows air into the sensor lens through the air guide pipe 42 and the air nozzle 43 to form an air curtain to prevent dust. The data from both are transmitted to the control panel 5. If a defect or abnormal temperature is detected, the alarm 34 will issue an audible and visual alarm to remind the operator to handle the situation, thus realizing real-time detection and control.
