Description

Technical Field

[0001] The present application relates to the field of straightness detection, and in particular to a photovoltaic frame straightness detection device. Background Art

[0002] Straightness, also known as straightness tolerance, refers to the total amount of variation allowed for a single actual straight line. During the profile processing, a photovoltaic frame straightness detection device is required to detect the straightness of the profile after forming in order to prevent the use of profiles that do not meet the inspection requirements.

[0003] In the traditional straightness detection structure, after the profile is clamped, the plane of the profile plate is measured by a laser rangefinder, and the data is transmitted to the computer to obtain the straightness of the profile. When one side is measured, the profile needs to be removed, flipped to the other side, and re-clamped before the other side can be measured. The steps are relatively cumbersome, resulting in low measurement efficiency. In addition, the movement of the profile will cause errors in the measurement results, and the accuracy of the measurement data cannot be guaranteed. Summary of the Invention

[0017] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0019] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0020] In the description of this utility model, the terms "upper," "lower," "left," and "right," etc., regarding orientations or positions, are based on the orientations or positions shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0021] like Figures 1 to 2 As shown, the present application discloses a photovoltaic frame straightness detection device, including at least two detection planes 1, adjacent detection planes 1 are rotatably connected, and at least one detection plane 1 is provided with at least two support seats 2 for placing profiles; each detection plane 1 is provided with at least three rangefinders 3, and the rangefinder 3 is used to detect the distance between the profile and the rangefinder 3.

[0022] The rangefinder 3 is a laser rangefinder.

[0023] The present application detects the distance between the profile 9 and the rangefinder 3 using at least three rangefinders 3 on the same plane, and compares multiple distance data to obtain the flatness of the plane of the profile 9; and by detecting the flatness of at least two planes on the profile 9 and integrating the plane information, the straightness of the profile 9 can be obtained. The detection method is simple and efficient, and the result obtained has a high accuracy.

[0024] Moreover, the present application can be embedded in a profile production line. The profile passes through the present application under the drive of the conveying device, and the distance meter 3 reads the distance data between the profile and the distance meter 3 to judge the straightness of the profile, and the detection efficiency is high.

[0025] In the present application, the number of distance meters 3 on a detection plane 1 is three, and a distance meter 3 is provided at each of the two ends of the profile 9, so that the straightness of the profile can be better detected.

[0026] The rangefinder 3 is further connected to an adjustment platform 31 , which is used to adjust the angle of the rangefinder 3 .

[0027] By adjusting the platform 31, it is ensured that the laser emitted by the rangefinder 3 can directly reach the surface of the profile, thereby ensuring the reliability of the measurement data.

[0028] At least one rangefinder 3 is connected to the detection plane 1 via a translation device 4, which is used to guide the movement of the rangefinder 3. The translation device 4 is a slide rail and slider mechanism to facilitate the movement of the translation device 4.

[0029] The detection position of the distance meter 3 can be adjusted by the translation device 4 to meet the needs of straightness detection of profiles 9 of different lengths and expand the applicability of this application. In order to ensure that the detection data has high reliability, the distance meter 3 needs to be calibrated after movement.

[0030] The translation devices 4 are all slide rail and slider mechanisms, which facilitate the movement of the translation devices 4.

[0031] In the present application, the two distance meters 3 corresponding to the ends of the profile 9 are connected to the detection plane through the conveying translation device 4, so as to better meet the requirements of the straightness detection of the profiles 9 of different lengths.

[0032] Furthermore, two corresponding rangefinders 3 mounted on the translation device 4 on different detection planes 1 are connected via a connecting bar 5 , and the connecting bar 5 is used to simultaneously move the two rangefinders located on different detection planes 1 .

[0033] By connecting the rangefinders 3 located on different detection planes 1 corresponding to the same detection position through the connecting bar 5, the mobile translation device 4 can directly move all the rangefinders 3 connected to it. The synchronous movement can reduce the adjustment difficulty, simplify the adjustment process, and improve the detection efficiency.

[0034] Furthermore, a driving member 51 is connected to the connecting bar 5 , and the driving member 51 is used to drive the connecting bar 5 to move.

[0035] The drive member 51 is electrically driven to perform adjustment, making the adjustment process more convenient. When the position of the rangefinder 3 needs to be adjusted, the drive member 51 drives the connecting bar 5 and the connecting bar 5 drives the rangefinder 3 to move to the desired position.

[0036] Furthermore, the distance meter 3 that is not connected to the detection plane 1 through the translation device 4 is also connected with a pad 6. The pad 6 ensures that the detection points of the distance meter 3 on the detection plane 1 are located on the same straight line, which can better ensure the reliability of the detection result.

[0037] A protrusion 21 is provided on the top surface of the support seat 2 , and the side surface of the protrusion 21 abuts against the profile 9 .

[0038] The projections 21 play a positioning role on the profile 9 .
