Description

Technical Field

[0001] The invention relates to the technical field of flatness detection equipment, and in particular to a flatness detection equipment capable of adaptively detecting aluminum alloy plates of different thicknesses. Background Art

[0002] Aluminum alloy plate is an industrial building material. It is used in various industries according to different materials. It can be divided into two categories according to the surface treatment method: non-painted products and painted products. The industries using it include aircraft structures, rivets, missile components, truck wheels, packaging and insulation aluminum foil, heat exchangers, bulkheads, wing ribs, wing beams, etc. Aluminum alloy plates are often used in high-precision occasions, so after processing, they need to be tested for flatness. If the flatness is not up to standard, it is difficult to meet the needs of the terminal industry. The Chinese patent publication number CN116124073A discloses a flatness detection machine for aluminum alloy plates that can adapt to different thicknesses. It includes a protective shell with a hollow cavity and a conveying mechanism fixedly installed in the middle of the protective shell. The conveying mechanism runs through the hollow cavity of the protective shell. A servo motor is provided on one side of one end of the conveying mechanism, which is located on the inner side of the protective shell near the input end of the conveying mechanism. A flatness detection mechanism is arranged on the side, and its characteristic is that the flatness detection mechanism includes a support rod and a support column fixedly arranged at one end of the support rod, the support column is movably connected with the protective shell, a detection plate is arranged at the lower end of the support rod, the lower end of the detection plate is close to the conveying mechanism, a reset torsion spring is fixedly arranged at the end of the support rod away from the support column, a transmission rod is fixedly arranged on the inner side of the reset torsion spring, the end of the transmission rod away from the reset torsion spring is connected with the torque sensor, and the torque sensor is electrically connected with the touch controller fixedly arranged on one side of the protective shell. It has strong practicality, and the detection and adaptation of aluminum alloy plates of different thicknesses are integrated with each other, and it automatically adapts to aluminum alloy plates of different thicknesses. It has the advantages of fast detection speed, high working efficiency and low design cost of the whole machine.

[0003] In the above-mentioned prior art, when aluminum alloy plates are leveled, they are often leveled by a leveling machine. After leveling, it is necessary to set up special equipment to measure whether the flatness meets the standards, or to manually check whether it is leveled. Since different operators have different judgment standards due to different experiences, the standardization and accuracy of the aluminum alloy plates are reduced, and the production quality of the aluminum alloy plates is reduced, affecting the continuous aluminum alloy plate production process. For this reason, a flatness detection device that can adapt to different thicknesses of aluminum alloy plates is proposed. Summary of the invention

[0004] In order to solve the problem that when aluminum alloy plates are leveled, they are usually leveled by a leveling machine, and after the leveling is completed, it is necessary to set up a special equipment to measure whether the flatness meets the standards, or to manually check whether it is leveled. Different operators have different judgment standards due to different experiences, which reduces the standardization and accuracy of the aluminum alloy plates, thereby reducing the production quality of the aluminum alloy plates and affecting the continuous aluminum alloy plate production process. The present invention provides a flatness detection device for aluminum alloy plates that can adapt to different thicknesses.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A flatness detection device for aluminum alloy plates that can adapt to different thicknesses comprises a flattening machine, a conveyor belt is installed on the flattening machine, a detection box is installed on the conveyor belt, a mesh plate is installed on the detection box, a straightening mechanism for straightening the aluminum alloy plate is installed on the detection box, the straightening mechanism is located on one side of the flattening machine, a trigger mechanism for detecting the flatness of the aluminum alloy plate is installed on the detection box, a screening mechanism for screening aluminum alloy plates that do not meet the standard flatness is arranged on the top side of the trigger mechanism, a transmission mechanism for driving the screening mechanism to move is installed on the detection box, the transmission mechanism is located on the top side of the trigger mechanism, and after the aluminum alloy plate is flattened by the flattening machine, the transmission mechanism is transmitted through the conveyor belt. It is transported to the inspection box for inspection of whether the flatness meets the standard. That is, when one end of the aluminum alloy plate contacts the trigger mechanism, the trigger mechanism works to detect the flatness. In this process, in order to ensure that the aluminum alloy plate completely blocks the mesh holes on the screen when passing through the inspection box, the aluminum alloy plate is automatically straightened by the straightening mechanism, thereby improving the scientific nature of the device. When an aluminum alloy plate that does not meet the flatness is encountered, the trigger mechanism drives the transmission mechanism to move, and the movement of the transmission mechanism drives the screening mechanism to automatically move to screen out the aluminum alloy plates that do not meet the standards, thereby realizing the flatness measurement in the continuous aluminum alloy plate leveling process and improving the convenience of equipment use.

[0006] Furthermore, the straightening mechanism includes a fixed block, which is installed on the detection box, and the fixed block is located at a side of the detection box close to the leveling machine. A sliding plate is slidably installed on the fixed block, and a connecting rotating plate is rotatably installed on the sliding plate. The sliding block is rotatably installed on the connecting rotating plate, and the sliding block is slidably installed on the detection box. A mounting plate is installed on the sliding block, and the mounting plate contacts the detection box. A rotating shaft is rotatably installed on the fixed block, and a vertical block is installed on the rotating shaft. The vertical block is located on one side of the leveling machine, and an adaptation groove is opened on the fixed block, and the adaptation groove is adapted to the vertical block. A gear is installed on the rotating shaft, and a tooth groove is opened on the sliding plate, and the gear is meshed with the tooth groove. When the aluminum alloy plate is transmitted to the top side of the fixed block on the conveyor belt, the vertical block and the rotating shaft are driven to rotate, and the rotation of the rotating shaft drives the gear to rotate. The rotation of the gear drives the sliding plate to slide on the fixed block. During the sliding process of the sliding plate, the connecting rotating plates on both sides are driven to move, and the movement of the connecting rotating plates drives the sliding blocks to slide close to each other. The sliding blocks slide close to each other, thereby facilitating the straightening of the passing aluminum alloy plate, thereby improving the practicability and scientificity of the device.

[0007] Furthermore, a T-shaped groove is provided on the fixed block, a T-shaped slider is installed on the sliding plate, and the T-shaped slider is slidably installed in the T-shaped groove. The T-shaped groove limits the movement of the T-shaped slider, and the T-shaped slider can and can only slide in the T-shaped groove, thereby realizing that the sliding plate can and can only slide on the fixed block.

[0008] Furthermore, a torsion spring is installed on the rotating shaft, and the torsion spring is installed on the fixed block. Through the setting of the torsion spring, after the aluminum alloy plate is inspected, the structure is reset under the action of the reset elastic force of the torsion spring, which facilitates the measurement of the next aluminum alloy plate and further improves the convenience of use of the device.

[0009] Furthermore, a telescopic shaft is slidably installed on the mounting plate, a straightening plate is installed on the telescopic shaft, a compression spring is movably sleeved on the telescopic shaft, one end of the compression spring is installed on the mounting plate, and the other end of the compression spring is installed on the straightening plate. When the mounting plates approach each other, the telescopic shaft and the straightening plate are driven to slide close to each other, which is convenient for elastic straightening of aluminum alloy plates of different widths, further improving the wide applicability of the structure. It should be noted that the surface of the straightening plate is smooth, which does not affect the sliding of the aluminum alloy plate under the action of the conveyor belt.

[0010] Furthermore, the trigger mechanism includes a control switch, which is installed on the detection box. The control switch is electrically connected to a wire, and the wire is electrically connected to a fan. The fan is installed on the bottom side of the detection box. A first sensor is installed at one end of the detection box, and a second sensor is installed at the other end of the detection box. The first sensor is located on a side of the detection box away from the leveling machine. The first sensor and the second sensor are electrically connected to the control switch. When one end of the aluminum alloy plate passes through the first sensor, the first sensor transmits an electrical signal to the control switch, and the control switch turns on the fan to start working. When the surface flatness of the aluminum alloy plate passing through does not meet the standard, the fan drives the screening mechanism to move when it sucks air through the mesh plate and passes through the screening mechanism, and the aluminum alloy plates that do not meet the standard are screened out. When the flatness of the aluminum alloy plate passing through meets the standard, when the other end of the aluminum alloy plate passes through the second sensor, the second sensor transmits an electrical signal to the control switch, and the control switch turns off the fan, thereby realizing a continuous detection process of the flatness of the aluminum alloy plate.

[0011] Furthermore, the screening mechanism includes a sliding rod, which is slidably mounted on the detection box, a bracket is mounted on the sliding rod, the bracket is located on the top side of the fan, the bracket and the mesh plate are located in the same horizontal plane, a limit screw is rotatably mounted on the bracket, a shift block is threadedly mounted on the limit screw, the shift block is slidably mounted on the bracket, a gear block is mounted on the limit screw, a toothed plate is mounted on the detection box, the toothed plate is adapted to the gear block, the gear block rotates under the restriction of the toothed plate when passing through the toothed plate, thereby driving the limit screw to rotate, the rotation of the limit screw drives the shift block to slide on the bracket, thereby pushing down the aluminum alloy plate on the bracket that does not meet the standard flatness from one side and removing it.

[0012] Furthermore, the transmission mechanism includes a roller, which is rotatably installed on the detection box, a rotary page is installed on the roller, the rotary page is located on the top side of the fan, a transmission gear is installed on the roller, a continuous tooth groove is opened on the sliding rod, the transmission gear is meshed with the continuous tooth groove, and when the flatness of the aluminum alloy plate does not meet the standard, the wind sucked in by the fan drives the rotary page to rotate, the rotation of the rotary page drives the transmission gear to rotate, and the rotation of the transmission gear drives the sliding rod and the bracket to slide on the detection box under the restriction of the continuous tooth groove, so that the gear block contacts and meshes with the tooth groove plate.

[0013] The beneficial effects of the present invention are as follows: The present invention, through the arrangement of the detection box, the mesh plate, the fan, the bracket and the like, realizes that in the continuous flatness detection process of the aluminum alloy plate, when an aluminum alloy plate that does not meet the standard flatness is detected, the turning page drives the rotation of the transmission gear to make the bracket rise and lift the aluminum alloy plate that does not meet the standard, and during the lifting process, the shifting block automatically slides to remove the aluminum alloy plate from one side of the detection box, thereby facilitating the flatness measurement of the aluminum alloy plate in the continuous flatness process and improving the convenience of using the equipment.

[0014] The present invention facilitates elastic straightening of aluminum alloy plates of different widths by arranging the straightening plate, the telescopic shaft, the compression spring and the like, thereby further improving the wide applicability of the structure.

[0015] The present invention, through the arrangement of rollers, rotary blades, transmission gears, etc., realizes that when the flatness of the aluminum alloy plate does not meet the standard, the wind sucked in by the fan drives the rotary blades to rotate, the rotation of the rotary blades drives the transmission gears to rotate, and the rotation of the transmission gears drives the sliding rods and the brackets to slide on the detection box under the restriction of continuous tooth grooves, so that the gear block contacts and meshes with the tooth groove plate, further improving the convenience of use and the degree of automation of the equipment.
