Description

Technical Field

[0001] The invention relates to the technical field of detection devices, in particular to an automatic detection device for the surface of aluminum profiles. Background Art

[0002] As an indispensable basic material in modern industry, aluminum profiles have unique performance advantages that drive the continuous expansion of their application areas. They have the performance advantages of lightweight, high strength and durability, excellent corrosion resistance, good electrical and thermal conductivity, stable chemical properties, good surface treatment performance, environmental protection and recyclability. According to statistics from the International Aluminum Association, the global aluminum profile market size is expected to reach US$180 billion in 2025, and every 1 percentage point reduction in the surface quality defect rate can save companies more than US$230 million in subsequent processing costs.

[0003] During the production process, aluminum profiles usually need to go through various surface inspection links, such as dimensional accuracy, surface flatness, and whether there are scratches on the surface. In the quality management system of aluminum profiles throughout their life cycle, the surface inspection link is facing the prominent contradiction between the mismatch between industrial production scale and inspection efficiency. At present, the traditional manual visual inspection mode or handheld eddy current flaw detector mode is usually used for aluminum profile surface inspection. Although these inspection modes can also be used for aluminum profile surface inspection, they will consume a lot of manpower and time in the process of batch inspection. When the surface of batch aluminum profiles needs to be inspected, the current inspection mode obviously cannot meet the needs of efficient inspection. The details are as follows: 1. In the traditional manual visual inspection mode, quality inspectors need to identify micron-level scratches with the naked eye under strong light conditions. Single-piece inspection takes a long time and is subject to the fluctuation of missed detection rate caused by the physiological limit of the human eye and visual fatigue. 2. Although the handheld eddy current flaw detector can detect pore inclusions within 3mm under the skin, it requires the operator to scan point by point along the axial direction of the profile, and the inspection speed is low. In the face of generally super-long building profiles, the single-piece inspection time is significantly longer. Summary of the invention

[0017] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] See Figure 1 and Figure 2The present invention provides an automatic surface detection device for aluminum profiles, comprising a detection cavity 1 with a hollow structure, wherein one or more telescopic cylinders 2 are respectively arranged at the top and bottom of the inner wall of the detection cavity 1, and pressure sensors 3 are installed at the telescopic ends of the telescopic cylinders 2. Sliding components are movably arranged on both sides of the inner wall of the detection cavity 1, and the sliding components are used to automatically detect the surface of the aluminum profile. The sliding components include a fixed rack 4, a rotating gear 5, a reduction motor 6, a sleeve 7, a base 8, an adjustment cylinder 9, a panel 10 and a support seat 11. Two fixed racks 4 are installed in parallel on the outer wall of the detection cavity 1, and the rotating gear 5 and the sleeve 7 are installed at the power output of the reduction motor 6. The rotating gear 5 is located on the outside of the detection cavity 1, and the sleeve 7 is located on the inside of the detection cavity 1. The rotating gear 5 is meshed and connected between the two fixed racks 4. The sleeve 7 penetrates into the inner cavity of the detection cavity 1 and is connected to the base 8. The middle of the base 8 is installed with an adjusting cylinder 9, and the telescopic end of the adjusting cylinder 9 is installed with a panel 10. The middle of the panel 10 is installed with a support seat 11, and the support seat 11 is installed with a detection device 12. The upper and lower ends of the panel 10 are both provided with a guide assembly, and the guide assembly includes an adjusting rod 13, an adjusting hand wheel 14 and a guide wheel 15. One end of the adjusting rod 13 passes through the panel 10 and is connected to the adjusting hand wheel 14, and the other end of the adjusting rod 13 is installed with the guide wheel 15. The operation process of the guide assembly is that the operator realizes the micro-extension of the adjusting rod 13 by turning the adjusting hand wheel 14, and then the contact between the guide wheel 15 and the surface of the aluminum profile can be adjusted.

[0019] Among them, the detection cavity 1 is a closed or semi-closed structure, which isolates external interference such as light, dust, oil, etc. to ensure the stability of the detection environment. If necessary, air flow vibration and temperature and humidity fluctuations must be strictly controlled. The inner wall material of the detection cavity 1 is anti-static and corrosion-resistant to avoid the adsorption of aluminum chips or dust. An automatic cleaning system can be integrated, such as an air gun purge or dust suction device, to reduce the maintenance frequency. According to the cross-sectional size and length of the aluminum profile, the detection cavity 1 can be designed as an adjustable or modular cavity to support the passage of aluminum profiles of different specifications. For continuous production lines, the seamless connection between the detection cavity 1 and the transmission system is guaranteed to avoid the jamming of the aluminum profile. The detection cavity 1 is made of lightweight, high-strength materials, taking into account wear resistance and corrosion resistance. The detection cavity 1 can be a transparent cavity, usually made of glass, polymer or other transparent materials. Such a design can facilitate the staff to see the internal situation of the detection cavity 1 through the transparent cavity, that is, to achieve real-time visual observation.

[0020] It should be noted that when a set of telescopic cylinders 2 is provided at the top of the inner wall of the detection cavity 1, a set of telescopic cylinders 2 is also provided at the bottom of the inner wall of the detection cavity 1, and the position of the upper set of telescopic cylinders 2 corresponds to the position of the lower set of telescopic cylinders 2; when two sets of telescopic cylinders 2 are provided at the top of the inner wall of the detection cavity 1, two sets of telescopic cylinders 2 are also provided at the bottom of the inner wall of the detection cavity 1, and the positions of the upper two sets of telescopic cylinders 2 correspond to the positions of the lower two sets of telescopic cylinders 2; and so on. The clamping force of the telescopic cylinder 2 on the aluminum profile is adjustable, and the deformation of the aluminum profile is avoided by air pressure regulation or proportional valve control. The end of the telescopic cylinder 2 is designed with damping to reduce the impact force at the moment of clamping.

[0021] Both ends of the guide wheel 15 are fixed by directional brackets 16. The directional bracket 16 is a supporting structure with direction guiding or structural orientation characteristics, so that the guide wheel 15 moves in a specific direction.

[0022] A cover 17 is hinged on the edge of the support base 11. The setting of the cover 17 can provide appropriate protection for the detection equipment 12 on the support base 11. Specifically, when the detection equipment 12 is working normally, the cover 17 can be opened freely; when the detection equipment 12 is not working, the cover 17 can be closed freely to provide appropriate protection for the detection equipment 12.

[0023] The detection cavity 1 is a cube structure, and an LED light source 18 is installed in the detection cavity 1. Preferably, LED light sources 18 are installed in the corners of the detection cavity 1. The LED light sources 18 need to be multi-angle and adjustable to facilitate uniform arrangement of the light sources, avoid reflections, shadows or overexposure, and ensure that the surface defects of the aluminum profile are clearly visible. In a dark working environment, the setting of the LED light source 18 can provide sufficient light for the detection process of the detection equipment 12, which can not only ensure the smooth progress of the aluminum profile surface detection work, but also ensure the accuracy of the aluminum profile surface detection.

[0024] A control box 19 is installed on the upper part of the detection chamber 1, and a display screen 20 is provided on the control box 19. A control button 21 is installed on one side of the display screen 20. The display screen 20 can display various data during the aluminum profile surface detection process, and the control button 21 can be used to control the working status of various electrical components.

[0025] The lower part of the detection cavity 1 is fixedly supported by the pillars 22. Specifically, there are two pillars 22, which are symmetrically arranged in an eight-shaped manner at the lower part of the detection cavity 1, thereby improving the structural strength and working stability of the overall detection device. The pillars 22 directly bear the detection cavity 1 and the internal and external loads to prevent the bottom of the detection cavity 1 from being deformed or collapsed due to excessive weight. The pillars 22 can be made of elastic materials such as rubber, so that the pillars 22 can absorb vibration energy and protect the precision equipment inside and outside the detection cavity 1.

[0026] A protective cover 23 is provided above the fixed rack 4, and the protective cover 23 is installed and fixed on the outer wall of the detection cavity 1. The setting of the protective cover 23 can play a good protective role for the fixed rack 4, the rotating gear 5 and the reduction motor 6, preventing them from being damaged by external forces or foreign objects, and also ensuring the smooth operation of them. The material selection of the protective cover 23 can be comprehensively considered according to the specific application scenario, and can be any one of metal materials, plastics and polymers, composite materials, etc.

[0027] The telescopic cylinder 2, pressure sensor 3, fixed rack 4, rotating gear 5, reduction motor 6, adjusting cylinder 9, detection equipment 12, LED light source 18, control box 19, display screen 20 and control button 21 in this application are all purchased directly from the market. Among them, the telescopic cylinder 2 and the adjusting cylinder 9 are driven by compressed air or hydraulic oil to achieve multi-stage telescopic movement. The pressure sensor 3 converts the pressure signal into an electrical signal, and converts the pressure value into a measurable electrical signal through physical deformation or change in material properties. The fixed rack 4 and the rotating gear 5 mesh and transmit, converting the rotational motion into linear motion. The reduction motor 6 converts the high-speed and low-torque output of the electric motor into a low-speed and high-torque output, and reduces the speed and amplifies the torque through a mechanical reduction mechanism.

[0028] The detection device 12 in the present application can be selected from a laser rangefinder, a high-definition camera, an ultrasonic flaw detector, etc. When the detection device 12 is a laser rangefinder or a laser three-dimensional scanner, the distance is calculated by emitting a laser beam and receiving a reflected signal, and the flatness error of the aluminum profile surface is automatically detected to determine whether it meets the flatness requirements, and the surface deformation, warping, cross-sectional size deviation and other geometric defects of the aluminum profile are automatically detected. When the detection device 12 is a high-definition camera, the high-definition camera converts the optical signal into a high-resolution digital image or video, and automatically detects scratches, pits, color difference, uneven oxidation and other defects on the surface of the aluminum profile. When the detection device 12 is an ultrasonic flaw detector, the ultrasonic flaw detector realizes accurate defect detection through the piezoelectric effect, which is suitable for internal defect detection of thick-walled aluminum profiles, such as pores and surface crack depth. When the detection device 12 is a surface roughness meter, the surface roughness meter is a contact structure or a non-contact structure. If the surface roughness meter adopts a contact structure, its principle is to use a probe made of diamond or cemented carbide to contact the surface of the aluminum profile to be tested. The probe moves along the surface of the aluminum profile and produces vertical displacement as the surface of the aluminum profile rises and falls; if the surface roughness meter adopts a non-contact structure, its principle is to use the interference phenomenon of light. The high and low surfaces cause optical path differences, forming interference fringes, and reconstructing the surface morphology by analyzing the fringe spacing or phase changes. The surface roughness meter is used to automatically detect the roughness, texture uniformity, etc. of the surface of the aluminum profile. When the detection device 12 is a coating thickness gauge, the coating thickness gauge automatically detects the thickness of the anodized, sprayed or electrophoretic layer on the surface of the aluminum profile. When the detection device 12 is a colorimeter, the colorimeter quantifies the color difference through the CIE Lab color space, automatically detects the consistency of the color after the coloring process of the aluminum profile surface, and avoids color differences between batches. When the detection device 12 is a metallographic microscope, the metallographic microscope automatically detects the intergranular corrosion and the microstructure of the oxide film on the surface of the aluminum profile.

[0029] The working principle of the aluminum profile surface automatic detection device is as follows: First, the telescopic cylinders 2 at the top and bottom of the inner wall of the detection cavity 1 are extended, and the extended telescopic cylinders 2 clamp the aluminum profile; then, various required detection equipment 12 are installed and fixed on the support seat 11; then, the control button 21 on the control box 19 is used to control the operation of the automatic detection components on both sides. The specific operation principle of the automatic detection components is: the reduction motor 6 drives the rotating gear 5 to rotate, and the rotating gear 5 drives the base 8 at one end of the sleeve 7 to move in the horizontal direction during the rotation. During the movement, the surface of the clamped aluminum profile will be detected. The guide components on both sides can be adjusted according to needs to ensure that the guide wheel 15 rolls and guides on the surface of the aluminum profile, thereby ensuring stability during the detection process.

[0030] The automatic surface detection device for aluminum profiles, through the integration of innovative mechanized structural design and intelligent detection technology, effectively solves the industry pain points of low efficiency, high cost and high missed detection rate of traditional manual detection. The device adopts a modular design architecture, and is mainly composed of a detection cavity 1, a telescopic cylinder 2, a pressure sensor 3, a sliding assembly and a guide assembly. Among them, the sliding assembly automatically detects the surface of the aluminum profile, and cooperates with the guide assembly to ensure the stability and detection accuracy of the detection process.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
