Description

Technical Field

[0001] This utility model belongs to the field of reflective aluminum plate processing technology, specifically relating to a device for detecting the surface flatness of reflective aluminum plates. Background Technology

[0002] Reflective aluminum can be used in a wide range of applications, including signs, nameplates, vehicle license plates, vehicle body reflectivity, and architectural decoration. Currently, the main production methods for reflective aluminum include coating the aluminum substrate with a reflective adhesive layer and a protective adhesive layer, or spraying a layer of glass microspheres onto the aluminum substrate. The reflective effect is achieved through the reflection of the reflective adhesive or the glass microspheres. The glass microsphere method also has the advantages of low production cost and environmental friendliness. The processing involves multiple steps, including unwinding, degreasing, pure water cleaning, dust removal, pure water cleaning, brightening, pure water cleaning, applying adhesive layer, spraying glass microspheres, drying, applying protective adhesive layer, drying again, and rewinding.

[0003] In the specific processing, since the reflective performance of reflective aluminum sheets mainly comes from the reflective properties of the reflective adhesive layer or the glass microsphere layer, the uniformity and flatness of the reflective adhesive layer or the glass microsphere layer are particularly important to the quality of reflective aluminum sheets. In order to ensure the uniform coating of reflective adhesive layers, protective adhesive layers, etc., or the uniform spraying of glass microspheres, it is necessary to ensure the flatness of the aluminum sheet surface. Especially for the processing method of spraying glass microspheres, in order to achieve the same reflective effect as reflective film, the glass microspheres need to be evenly distributed on the same plane. Therefore, it is very important to detect the flatness of the aluminum substrate surface during the processing to improve the production quality of reflective aluminum sheets.

[0004] Therefore, it is necessary to develop a surface flatness detection device for reflective aluminum plates in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for detecting the surface flatness of reflective aluminum plates, which can quickly detect the surface flatness of aluminum plates, is convenient and quick to use, highly adaptable, and highly accurate.

[0006] The purpose of this utility model is achieved as follows: A device for detecting the surface flatness of reflective aluminum plates includes a support base, on which a lifting support rod is provided. The lifting support rod is connected to a lifting drive assembly. A fixed sleeve and a sliding sleeve are respectively provided on the lifting support rod. A horizontal support plate is rotatably hinged to one side of the fixed sleeve. An adjusting rod is rotatably hinged to the top of the other end of the horizontal support plate. The other end of the adjusting rod is rotatably hinged to the sliding sleeve. The lifting support rod, the horizontal support plate, and the adjusting rod together form a triangular support structure. An adjusting drive assembly is fixedly connected to the other side of the sliding sleeve. The adjusting drive assembly drives the sliding sleeve to move up and down. During the up and down movement of the sliding sleeve, the tilt angle of the outer end of the horizontal support plate is adjusted by the adjusting rod. The horizontal support plate is located above the aluminum plate to be tested. Multiple sets of distance measuring sensor assemblies are provided at the bottom of the horizontal support plate, and the distance measuring sensor assemblies are facing the aluminum plate to be tested.

[0007] Furthermore, the bottom of the support base is also equipped with self-locking omnidirectional casters.

[0008] Furthermore, the lifting support rod includes an outer cylinder fixedly mounted on a support base, an inner rod slidably mounted inside the outer cylinder, the top end of the inner rod extending out of the outer cylinder, and a drive connecting plate fixedly mounted on one side of the inner rod, the drive connecting plate being fixedly connected to the output end of the lifting drive assembly.

[0009] Furthermore, the fixed sleeve is detachably fixed to the inner rod by a bolt assembly, and the sliding sleeve is slidably connected to the inner rod by a sliding groove slider assembly.

[0010] Furthermore, the lifting drive assembly and the adjustment drive assembly are respectively implemented using a pneumatic cylinder assembly or a hydraulic cylinder assembly.

[0011] Furthermore, a level is provided on the horizontal support plate.

[0012] Furthermore, the level is implemented using a bubble level assembly.

[0013] Furthermore, the ranging sensor assembly is implemented using an infrared ranging sensor assembly.

[0014] The beneficial effects of this utility model are as follows: By installing an infrared ranging sensor assembly above the aluminum sheet, the surface of the aluminum sheet is detected. When the infrared ranging sensor assembly detects a change in value exceeding the normal error value, the surface of the aluminum sheet is uneven, making the detection convenient, quick, and efficient. By placing the ranging sensor assembly at the bottom of a horizontal support plate, and using a triangular support structure formed by a lifting support rod, a horizontal support plate, and an adjusting rod, along with their hinged connections, stable support is provided for the ranging sensor assembly. Furthermore, the upward or downward tilt angle of the outer end of the horizontal support plate can be adjusted by moving the sliding sleeve up and down, thereby adjusting the levelness of the horizontal support plate and ensuring that the ranging sensor assembly remains level relative to the aluminum sheet, guaranteeing detection effectiveness and improving detection accuracy. In summary, this utility model has the advantages of high detection efficiency, high accuracy, and convenient and quick use. Attached Figure Description

[0018] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1As shown, a device for detecting the surface flatness of reflective aluminum plates includes a support base 1, on which a lifting support rod 2 is mounted. The lifting support rod 2 is connected to a lifting drive assembly 3. Preferably, the lifting support rod 2 includes an outer cylinder 2a fixedly mounted on the support base 1, and an inner rod 2b slidably mounted inside the outer cylinder 2a. The top end of the inner rod 2b extends out of the outer cylinder 2a. A drive connecting plate 2c is fixedly mounted on one side of the inner rod 2b. The drive connecting plate 2c is fixedly connected to the output end of the lifting drive assembly 3. The lifting drive assembly 3 drives the drive connecting plate 2c to move up and down, thereby adjusting the height of the inner rod 2b by moving it up and down. Specifically, the sliding up and down movement of the inner rod 2b within the outer cylinder 2a can be achieved through a sliding groove slider assembly. This sliding groove slider assembly is existing technology and can be implemented in various ways, therefore no specific limitation is made. Preferably, the lifting drive assembly 3 can employ a pneumatic cylinder assembly or a hydraulic cylinder assembly to achieve its linear drive lifting function. Both pneumatic and hydraulic cylinder assemblies are existing technologies and can be implemented in various ways, therefore no specific limitation is made. Preferably, the bottom of the support base 1 is also equipped with self-locking universal casters, facilitating flexible movement of the entire device, enhancing its adaptability, broadening its application range, and making it more convenient and faster to use.

[0020] The lifting support rod 2 is provided with a fixed sleeve 4 and a sliding sleeve 5. Preferably, the fixed sleeve 4 is detachably fixed to the inner rod 2b by a bolt assembly, and the sliding sleeve 5 is slidably connected to the inner rod 2b by a sliding slider assembly. The bolt assembly and the sliding slider assembly are both existing technologies and can be implemented in various ways, so no specific limitation is made. A horizontal support plate 6 is rotatably hinged to one side of the fixed sleeve 4, and an adjusting rod 7 is rotatably hinged to the top of the other end of the horizontal support plate 6. The other end of the adjusting rod 7 is rotatably hinged to the sliding sleeve 5. The lifting support rod 2, the horizontal support plate 6 and the adjusting rod 7 together form a triangular support structure.

[0021] The sliding sleeve 5 is fixedly connected to an adjustment drive assembly 8 on its other side. The adjustment drive assembly 8 drives the sliding sleeve 5 to move up and down. During the up and down movement of the sliding sleeve 5, the tilt angle of the outer end of the horizontal support plate 6 is adjusted by the adjustment rod 7. Specifically, to Figure 1Taking the up, down, left, and right directions as an example, when the adjusting drive assembly 8 drives the sliding sleeve 5 to move upward, one end of the adjusting rod 7 connected to the sliding sleeve 5 moves upward with the sliding sleeve 5, and the other end pulls the horizontal support plate 6 upward and to the left. When the adjusting drive assembly 8 drives the sliding sleeve 5 to move downward, one end of the adjusting rod 7 connected to the sliding sleeve 5 moves downward with the sliding sleeve 5, and the other end pushes the horizontal support plate 6 downward and to the left, thereby fine-tuning the levelness of the horizontal support plate 6, so that the distance sensor assembly 9 set at the bottom of the horizontal support plate 6 can better detect the distance of the aluminum plate. Preferably, the adjusting drive assembly 8 can be implemented by a cylinder assembly or a hydraulic cylinder assembly. The cylinder assembly and hydraulic cylinder assembly are existing technologies and can be implemented in various ways, so no specific limitation is made.

[0022] The horizontal support plate 6 is located above the aluminum plate to be tested. Multiple sets of distance sensor assemblies 9 are installed at the bottom of the horizontal support plate 6, facing the aluminum plate. The distance sensor assemblies 9 detect surface irregularities on the aluminum plate. If the distance sensor assemblies 9 detect a change in value exceeding the normal error value, the surface of the aluminum plate is uneven. Preferably, the distance sensor assemblies 9 are infrared distance sensor assemblies. Specifically, the aluminum plate to be tested can be mounted on a frame below the horizontal support plate 6 and the distance sensor assemblies 9, or it can be mounted on a frame using a set of transfer rollers below the horizontal support plate 6 and the distance sensor assemblies 9. The aluminum plates to be tested are sequentially transmitted, allowing them to pass under the ranging sensor assembly 9 in sequence, achieving automatic and continuous detection with better results and higher efficiency. It should be noted that the frame and transmission roller assembly are conventional technical means in aluminum processing and are very common existing technologies. They are common knowledge to those skilled in the art, and no other special requirements are made in this application. It is sufficient that they can achieve the functions described in this application, so no specific limitations are made here. Preferably, a level 10 is also provided on the horizontal support plate 6. The level 10 can be used to detect the current levelness of the horizontal support plate 6 in real time, which is convenient for timely adjustment. The level 10 can be implemented using a bubble level assembly.

[0023] The system also includes a controller and a drive power supply. The controller and drive power supply can be electrically connected to the lifting drive assembly 3, the adjustment drive assembly 8, and the ranging sensor assembly 9 via power lines or other means. The controller, drive power supply, lifting drive assembly 3, adjustment drive assembly 8, ranging sensor assembly 9, and their specific circuit connection structures are existing technologies and are common knowledge to those skilled in the art. No other special requirements are made in this application, as long as they can achieve the functions described in this application. Therefore, no specific limitations are made here.

[0024] In a specific implementation of this utility model, the lifting drive assembly 3 drives the inner rod 2b to move up and down, adjusting the horizontal support plate 6 to a suitable height; then, the horizontal support plate 6 undergoes initial calibration and positioning adjustment to achieve this. Figure 1 The embodiment shown has two sets of ranging sensor assemblies 9 and Figure 1 Taking the up, down, left, and right directions as an example, when both sets of distance sensor components 9 are activated, if the current distance values ​​of the two sets of distance sensor components 9 are the same, no further adjustment is needed. If the current test values ​​of the two sets of distance sensor components 9 are different, and the distance value on the left is larger than that on the right, then the adjustment drive component 8 is activated to move the sliding sleeve 5 upward. One end of the adjustment rod 7 connected to the sliding sleeve 5 moves upward with the sliding sleeve 5, while the other end rotates the horizontal support plate 6 upward and to the left until the distance values ​​on both sides are the same. If the distance value on the right is larger than that on the left, then the adjustment is activated. The section drive assembly 8 drives the sliding sleeve 5 to move downwards. One end of the adjusting rod 7 connected to the sliding sleeve 5 moves downwards along with the sliding sleeve 5, while the other end pushes the horizontal support plate 6 downwards and to the left until the distance measurement values ​​on both sides are consistent. After completing the calibration and positioning adjustment of the horizontal support plate 6, the distance sensor assembly 9 is activated to measure the flatness of the aluminum plate to be measured below it. When the distance sensor assembly 9 detects a change in the value that exceeds the normal error value, it can be determined that there is an unevenness on the surface of the aluminum plate. The operation is convenient, quick, and labor-saving, with high detection efficiency and high accuracy.
