[0023] When a longer strip is detected, the ruler can be disassembled by adjusting the bolt to facilitate the placement of the strip on the horizontal platform.

[0024] One of the two vertical supports is a movable support that can move along the direction of the ruler, and the other is a fixed support, and the fixed part is arranged at the movable support.

[0025] The tension meter is connected with the control module, when the horizontal force measured by the tension meter reaches 5N, the control module determines that the horizontal force measured by the tension meter reaches the measurement requirement, and sends a digital quantity control signal to the automatic reading device, so that the automatic reading device reads the ruler scale corresponding to the position of the fixed part.

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

[0030] The method for automatically detecting the width of the aluminum alloy plate strip adopts the device for automatically detecting the width of the aluminum alloy plate strip, and the method is characterized in that: when the plate strip is measured, the fixed support is first contacted with one side of the plate strip, then the movable support is moved to the other edge of the plate strip, until the fixed part of the movable support presses the plate strip, the tension meter measures the pressure applied to the plate strip by the fixed part, when the measured pressure reaches the measurement standard, the plate strip is reliably clamped by the two vertical supports and is in a measurable state, and the automatic reading device reads and identifies the ruler scale corresponding to the position of the fixed part.

[0031] Embodiment:

[0032] The device in the example comprises a horizontal platform, a vertical support frame, an F-shaped scale, a small tension meter, and an automatic reading device. The aluminum alloy plate strip to be measured is placed on the horizontal platform and inside the F-shaped scale. The clamping force between the sample to be measured and the measuring device is controlled by the small tension meter on the vertical support frame to 5N to ensure the consistency of the measurement method. Finally, the automatic reading device automatically reads the width of the plate strip to be measured.

[0033] The horizontal platform has a width of less than 3 meters, and two vertical support frames are placed on both sides of the horizontal platform. The upper ends of the support frames are welded with L-shaped connectors for the horizontal placement of the sample to be measured.

[0034] The L-shaped connectors are automatically adjusted and rotated by adjusting bolts to fix the scale. The heights of the L-shaped connectors on both sides of the support frame are consistent to ensure that the scale is fixed on the horizontal platform and facilitate the installation of a sensor.

[0035] The F-shaped scale has a horizontal bar with a length of 3 meters and standard markings on it with a minimum accuracy of 0.01 mm. One side of the vertical scale is in contact with the sensor in claim 3, and the other side is in contact with the automatic reading device in claim 1. When measuring automatically, the aluminum alloy plate strip to be measured is placed in the middle of the F-shaped scale so that the ends of the sample to be measured are in contact with the scale.

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

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

[0038] Therefore, the purpose of the present application is to provide a device and method for automatically detecting the width of an aluminum alloy plate strip, which is convenient to use and beneficial to the rapid and effective automatic detection of the width of the aluminum alloy plate strip.

[0039] The device and method for automatically detecting the width of an aluminum alloy plate strip are implemented by the following scheme: (1) placing the aluminum alloy plate strip to be measured on the horizontal platform and inside the F-shaped scale; (2) controlling the clamping force between the sample to be measured and the measuring device by the small tension meter on the vertical support frame to 5N to ensure the consistency of the measurement method; and (3) finally, the automatic reading device automatically reads the width of the plate strip to be measured.

[0040] Further, 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. The upper ends of the support frames on both sides are welded with L-shaped connectors. The L-shaped connectors can be automatically adjusted in rotation and fixed to the scale through adjusting bolts. The heights of the L-shaped connectors welded on both sides of the support frames are consistent, ensuring that the scale is fixed horizontally.

[0041] Further, 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 pressure when the sensor contacts the scale can be detected through the small tension meter, ensuring that the automatic measurement is controlled under the same pressure (5N in this example). This reduces the influence of human error in measurement. When the small tension meter detects a tension of 5N, it sends a digital signal to the automatic reading device. When the automatic reading device receives the signal, it performs automatic reading.

[0042] Further, in step (2), the scale is F-shaped, with a horizontal rod length of 3 meters. The horizontal rod has standard markings with a minimum accuracy of 0.02mm. One side of the vertical scale contacts the sensor in claim 3, and the other side contacts the automatic reading device in claim 1. When automatic measurement is required, the aluminum alloy strip to be measured is placed in the middle of the F-shaped scale, ensuring that the ends of the sample are in contact with the scale. At the same time, the reading of the small tension meter in claim 3 is uniformly controlled at 5N, and the reading can be taken as the actual reading through the automatic reading device.

[0043] Further, in step (3), a portable mobile trolley is equipped on the scale to achieve automatic movement. The mobile trolley is equipped with an automatic reading device, which is equipped with a high-definition camera. The high-definition camera can automatically capture the direction of the scale line pointer. Through the automatic scale line pointer method, the sensor can display the camera data on the automatic reading device, realizing the automatic detection method.

[0044] In this example, the F-shaped scale imitates the structure of a vernier caliper, the scale of the horizontal arm imitates the scale of the main scale of the vernier caliper, the two vertical arms of the F-shaped scale imitate the movable measuring jaw of the vernier caliper, i.e. imitate the movable measuring jaw to clamp the measured strip, the trolley where the automatic reading device is located imitates the vernier scale of the vernier caliper, and the vernier scale is set, when the automatic reading device reads and identifies the scale of the fixed part, the high-definition camera reads the scale of the main scale and the vernier scale at the same time, and the difference between the line distance on the main scale and the line distance on the vernier scale is used to read the decimal part, so as to greatly improve the measurement accuracy; for example, when the line distance on the main scale (horizontal arm) is 1mm, the vernier scale (trolley) has 10 grids, and the line distance is 0.9mm, the zero lines of the two coincide, if the vernier scale moves 0.1mm, the first line of the vernier scale coincides with the first line of the main scale; if the vernier scale moves 0.2mm, the second line of the vernier scale coincides with the second line of the main scale. By analogy, the decimal part of the measured value can be read from the coinciding lines of the vernier scale and the main scale.

[0045] In this example, if the measured strip is a relatively thin strip, clamps are arranged at the two vertical arms of the F-shaped scale to stretch and flatten the strip, and the tension meter measures the tension during the stretching and flattening process to maintain the consistency of the width detection environment.
