Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a device for automatically detecting the width of an aluminum alloy plate or strip. Background Art

[0002] Aluminum alloy plates and strips have good ductility and are mainly formed by rolling processes. Different types of products can be produced through different production processes. The products have a wide range of applications, which indirectly affects the inconsistency of product dimensions. Therefore, the width of aluminum alloy products must be verified, controlled, and accepted during the production process. At present, the detection method of aluminum alloys is all through offline manual detection. Due to the influence of human factors during manual detection, there will be differences, which further affects the dimensional results. At the same time, offline detection is time-consuming and cannot be mechanized, which affects the effectiveness. There are also methods and devices that use laser width detection on the market. This method is effective but not economical. It has relatively high accuracy, but the equipment is expensive, making it difficult to achieve low cost and high use efficiency. Moreover, this method can only be fixed on the equipment, which is not practical enough. Summary of the Invention

[0004] The utility model adopts the following technical solutions.

[0005] A device for automatically detecting the width of an aluminum alloy plate or strip, comprising a control module, an F-type scale (3) for detecting the width, and a horizontal platform (1) for placing the plate or strip to be measured, wherein the platform is placed below the scale area of ​​the scale, and the scale is provided with a fixing member for ensuring that the horizontal stress state of the plate or strip in the scale direction meets the measurement requirements, and an automatic reading device is also provided; the fixing member is provided with a tension meter (4) for measuring the horizontal stress of the plate or strip in the scale direction, and when the horizontal stress measured by the tension meter meets the measurement requirements, the automatic reading device (5) reads and identifies the scale scale corresponding to the position of the fixing member to obtain the width of the current plate or strip to be measured.

[0006] When the thickness of the plate and strip is greater than the threshold, the horizontal force on the plate and strip in the scale direction is horizontal pressure, which is used to make the fixing part press the edge of the plate and strip according to the pre-pressure required for width measurement to ensure that the width detection environment of each plate and strip to be measured is the same.

[0007] The two ends of the F-shaped scale are respectively placed on the top of two vertical support frames (2) beside the platform. The scale is fixed to the top of the support frame with an L-shaped connector, and the fixed posture of the scale is adjusted by adjusting bolts so that the heights of the two ends of the scale are consistent and the scale is in a horizontal posture.

[0008] One of the two vertical support frames is a movable support that can move along the scale direction, and the other is a fixed support. The fixing member is arranged at the movable support.

[0009] The tensiometer is connected to the control module. When the horizontal force measured by the tensiometer reaches 5N, the control module determines that the horizontal force measured by the tensiometer meets the measurement requirements and sends a digital control signal to the automatic reading device, so that the automatic reading device reads the scale scale corresponding to the position of the fixing part.

[0010] The scale is in a horizontal F shape, comprising a horizontal arm and two vertical arms. The horizontal arm is a horizontal rod with a standard scale. Of the two vertical arms of the scale, one is connected to a tensiometer, and the other is a trolley for fixing an automatic reading device; the mobile trolley moves along the trolley channel at the horizontal arm.

[0011] The automatic reading device includes a high-definition camera. When the automatic reading device reads the scale mark corresponding to the position of the fixed part, the trolley moves along the horizontal arm toward the fixed part until the positioning part at the bottom of the trolley contacts the fixed part. At this time, the scale mark on the horizontal arm where the trolley is located is the scale mark corresponding to the position of the fixed part. The automatic reading device captures and identifies the scale mark with the high-definition camera.

[0012] The automatic reading device is provided with a display screen for displaying scale identification data.

[0013] The length of the horizontal rod is three meters, and the minimum accuracy of the automatic reading device in capturing and identifying the scale graduations through a high-definition camera is 0.01 mm.

[0014] A method for automatically detecting the width of aluminum alloy plates and strips adopts the device for automatically detecting the width of aluminum alloy plates and strips described above, and is characterized in that: the method is specifically: when measuring the plate and strip, first make the fixed bracket contact with one side of the plate and strip, and then move the movable bracket to the other edge of the plate and strip until the fixing part of the movable bracket presses the plate and strip, and the tension meter measures the pressure applied by the fixing part to the plate and strip. When the measured pressure reaches the measurement standard, the plate and strip are reliably clamped by the two vertical support brackets and are in a measurable state, and the automatic reading device reads and identifies the scale scale corresponding to the position of the fixing part.

[0015] Compared with the existing technology, the utility model has the following beneficial effects: the utility model provides a device for automatically detecting the width of aluminum alloy plates and strips. The measuring tool is simple, the investment cost is low, it is easy to operate, the detection is convenient, and the operability is strong. It can be widely used in the automatic width detection of aluminum alloy plates and strips at the production site, and can effectively perform automatic width detection on offline plates and strips, and can be conveniently used in industrialization.

[0016] In the present invention, a small tension meter can be used to detect the pressure when the plate and strip material, sensor and scale are in contact, ensuring that the automatic measurement is controlled under the same pressure (uniformly determined to be 5N). When the small tension meter detects that the tension reaches 5N, it sends a digital signal to the automatic reading device. When the automatic reading device receives the signal, it performs the automatic reading action, thereby reducing the influence of human errors in the measurement, maintaining the consistency of the force on the strip in the width detection environment, forming a unified detection specification, and improving the reliability of the detection data.

[0020] like Figure 1 As shown, a device for automatically detecting the width of an aluminum alloy plate and strip is provided. The device comprises a control module, an F-type scale (3) for detecting the width, and a horizontal platform (1) for placing the plate and strip to be measured, wherein the platform is placed below the scale area of ​​the scale, and the scale is provided with a fixing member for making the horizontal stress state of the plate and strip in the scale direction meet the measurement requirements, and is also provided with an automatic reading device; the fixing member is provided with a tension meter (4) for measuring the horizontal stress of the plate and strip in the scale direction, and when the horizontal stress measured by the tension meter meets the measurement requirements, the automatic reading device (5) reads and identifies the scale scale corresponding to the position of the fixing member to obtain the width of the current plate and strip to be measured.

[0021] When the thickness of the plate and strip is greater than the threshold, the horizontal force on the plate and strip in the scale direction is horizontal pressure, which is used to make the fixing part press the edge of the plate and strip according to the pre-pressure required for width measurement to ensure that the width detection environment of each plate and strip to be measured is the same.

[0022] The two ends of the F-shaped scale are respectively placed on the top of two vertical support frames (2) beside the platform. The scale is fixed to the top of the support frame with an L-shaped connector, and the fixed posture of the scale is adjusted by adjusting bolts so that the heights of the two ends of the scale are consistent and the scale is in a horizontal posture.

[0023] When testing longer strips, the scale can be removed by adjusting the bolts to facilitate placing the strip on a horizontal platform.

[0024] One of the two vertical support frames is a movable support that can move along the scale direction, and the other is a fixed support. The fixing member is arranged at the movable support.

[0025] The tensiometer is connected to the control module. When the horizontal force measured by the tensiometer reaches 5N, the control module determines that the horizontal force measured by the tensiometer meets the measurement requirements and sends a digital control signal to the automatic reading device, so that the automatic reading device reads the scale scale corresponding to the position of the fixing part.

[0026] The scale is in a horizontal F shape, comprising a horizontal arm and two vertical arms. The horizontal arm is a horizontal rod with a standard scale. Of the two vertical arms of the scale, one is connected to a tensiometer, and the other is a trolley for fixing an automatic reading device; the mobile trolley moves along the trolley channel at the horizontal arm.

[0027] The automatic reading device includes a high-definition camera. When the automatic reading device reads the scale mark corresponding to the position of the fixed part, the trolley moves along the horizontal arm toward the fixed part until the positioning part at the bottom of the trolley contacts the fixed part. At this time, the scale mark on the horizontal arm where the trolley is located is the scale mark corresponding to the position of the fixed part. The automatic reading device captures and identifies the scale mark with the high-definition camera.

[0028] The automatic reading device is provided with a display screen for displaying scale identification data.

[0029] The length of the horizontal rod is three meters, and the minimum accuracy of the automatic reading device in capturing and identifying the scale graduations through a high-definition camera is 0.01 mm.

[0030] A method for automatically detecting the width of aluminum alloy plates and strips adopts the device for automatically detecting the width of aluminum alloy plates and strips described above, and is characterized in that: the method is specifically: when measuring the plate and strip, first make the fixed bracket contact with one side of the plate and strip, and then move the movable bracket to the other edge of the plate and strip until the fixing part of the movable bracket presses the plate and strip, and the tension meter measures the pressure applied by the fixing part to the plate and strip. When the measured pressure reaches the measurement standard, the plate and strip are reliably clamped by the two vertical support brackets and are in a measurable state, and the automatic reading device reads and identifies the scale scale corresponding to the position of the fixing part.

[0031] Example:

[0032] The device in this example includes a horizontal platform, a vertical support frame, an F-type ruler, a small tensiometer, and an automatic reading device. By placing the aluminum alloy plate and strip to be tested on the horizontal platform and the inner side of the F-type ruler, the small tensiometer on the vertical support frame controls the clamping force of 5N between the sample to be tested and the measuring device to ensure the consistency of the measurement method. Finally, the automatic reading device automatically reads the width of the plate and strip to be tested.

[0033] The horizontal platform: The width of the horizontal platform can be controlled within 3 meters. Two vertical support frames can be placed on both sides of the horizontal platform. The upper ends of the two support frames are welded with L-shaped connectors to facilitate the horizontal placement of the sample to be tested.

[0034] The vertical support frame: The L-shaped connector can automatically adjust the rotation and fix the scale through the adjusting bolt. The L-shaped connectors welded on both sides of the support frame are of the same height, ensuring that the scale is fixed on the level, which is convenient for installing a sensor.

[0035] Among them, the F-type ruler: the ruler is F-type, in which the horizontal rod of the ruler is 3 meters long, and there is a standard scale on the horizontal rod of the ruler with a minimum accuracy of 0.01mm. One side of the vertical ruler contacts the sensor of the small tensiometer, and the other side contacts the automatic reading device of the trolley. During automatic measurement, the aluminum alloy plate and strip to be tested needs to be placed in the middle of the F-type so that both ends of the sample to be tested are in contact with the ruler.

[0036] The small tension meter is installed on the support frame to detect the transverse tension value of the strip. The value can be adjusted between 3-10N and is equipped with a 24V output port.

[0037] The automatic reading device automatically reads the scale value and can receive a 24V input signal to control the automatic reading action and can hold the reading value.

[0038] In view of this, the purpose of the present invention is to provide a device for automatically detecting the width of aluminum alloy plates and strips. The easy-to-use device for automatically detecting the width of aluminum alloy plates and strips is conducive to the rapid and effective automatic detection of the width of aluminum alloy plates and strips.

[0039] In this example, the following scheme is used to realize a device for automatically detecting the width of aluminum alloy plates and strips, including the following steps: (1) placing the aluminum alloy plates and strips to be tested on a horizontal platform and placing them on the inside of the F-type ruler; (2) controlling the clamping force of 5N between the sample to be tested and the measuring device through a small tensiometer on a vertical support frame to ensure the consistency of the measurement method; (3) finally automatically reading the width of the plate and strip to be tested through an automatic reading device.

[0040] Furthermore, in step (1), the horizontal platform needs to be flat, and the platform width can be controlled within 3 meters. Two vertical support frames can be placed on both sides of the horizontal platform. There are welded L-shaped connectors on the upper ends of both sides of the support frames. The L-shaped connectors can be automatically adjusted and rotated by adjusting bolts to complete the fixation of the ruler. The height of the L-shaped connectors welded on the support frames on both sides is consistent to ensure that the ruler is fixed on the level.

[0041] Furthermore, in step (2), a small tension meter is installed on the vertical support frame. The upper end of the support frame is equipped with a small tension meter. The small tension meter can measure the pressure when the sensor contacts the scale, ensuring that the automatic measurement is controlled under the same pressure (uniformly determined to be 5N in this example) to reduce the influence of human error in the measurement. When the small tension meter detects that the tension reaches 5N, it sends a digital signal to the automatic reading device. When the automatic reading device receives the signal, it performs the automatic reading action.

[0042] Furthermore, in step (2), the scale is F-type, wherein the length of the horizontal rod of the scale is 3 meters, the horizontal rod of the scale has a standard scale with a minimum accuracy of 0.02 mm, one side of the vertical scale contacts the small tensiometer sensor, and the other side contacts the trolley automatic reading device. During automatic measurement, the aluminum alloy plate and strip to be measured needs to be placed in the middle of the F-type so that both ends of the sample to be measured fit the scale, and at the same time, ensure that the reading of the small tensiometer is uniformly controlled at 5N before it can be read by the automatic reading device, and the reading is taken as the actual reading.

[0043] Furthermore, in step (3), the ruler is equipped with a portable mobile trolley channel, which can realize automatic movement. The mobile trolley is equipped with an automatic reading device, which is equipped with a high-definition camera. The pointer direction of the scale line can be automatically captured by the high-definition camera. Through the content of the automatic scale line pointer method, the camera data can be displayed on the automatic reading device through the sensor, realizing the automatic detection method.

[0044] In this example, the F-shaped scale is modeled after the structure of a vernier caliper. The scale of its horizontal arm is set to imitate the scale of the main scale of the vernier caliper. The two vertical arms of the F-shaped scale are designed to imitate the movable jaws of the vernier caliper, that is, the movable jaws are used to clamp the plate and strip to be measured. The trolley where the automatic reading device is located imitates the vernier scale of the vernier caliper and sets the vernier grid. When the automatic reading device reads and identifies the scale scale corresponding to the position of the fixed part, the high-definition camera reads the main scale scale and the vernier scale vernier grid at the same time. The decimal point is read from the difference between the line spacing on the main scale and the line spacing on the vernier scale, significantly improving measurement accuracy. For example, when the line spacing on the main scale (horizontal arm) is 1 mm and the vernier scale (trolley) has 10 divisions with a line spacing of 0.9 mm, the zero lines of the two scales coincide. If the vernier scale moves 0.1 mm, its first line coincides with the first line of the main scale; if the vernier scale moves 0.2 mm, its second line coincides with the second line of the main scale. Similarly, the decimal point of the value can be read from the point where the lines on the vernier scale and the main scale coincide.

[0045] In this example, if the plate and strip to be tested is a thinner strip, clamps are set at the two vertical arms of the F-shaped scale to stretch and flatten the strip. The tensiometer measures the tension during the stretching and flattening process to maintain consistency in the width detection environment.
