Description

Technical Field

[0001] This invention relates to the technical field of laser inspection devices, specifically a laser inspection device for multi-angle decorative strip beams in curtain wall units. Background Technology

[0002] In current conventional unitized glass curtain wall projects, each unit is usually equipped with a decorative strip, which is aligned with the column. This not only optimizes the lighting effect, but also allows the decorative strip to be easily connected to the column in both horizontal and vertical directions through simple support connectors. During installation, the decorative strip needs to be connected to the crossbeam through the support, which places high demands on the forming quality of the crossbeam.

[0003] When inspecting the flatness and verticality of beams, operators typically move a level and measuring tools by hand instead of using a laser inspection device. This can lead to significant errors when taking multiple measurements, and the traditional inspection method is inefficient and not suitable for batch inspection. Summary of the Invention

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example 1 like Figures 1-9As shown, a laser inspection device for multi-angle decorative strip beams of curtain wall units includes a conveying mechanism 2, a lower inspection mechanism 3, a left inspection mechanism 4, and a right inspection mechanism 5. The conveying mechanism 2 is used to convey beam units 1. Along the conveying mechanism 2, the lower inspection mechanism 3 for inspecting the lower end face of the beam unit 1, the left inspection mechanism 4 for inspecting the left side face of the beam unit 1, and the right inspection mechanism 5 for inspecting the right side face of the beam unit 1 are sequentially arranged. The lower inspection mechanism 3 includes at least one row of inspection units 31, a lifting plate 32 for supporting the inspection units 31, lifting units 33 connected to the lifting plate 32, and several sets of components connected to the inspection units 31. The laser detection module 34 is arranged at intervals; the left detection mechanism 4 includes at least one row of detection units 31, a rotating plate 41 for supporting the detection units 31, a first driving unit 42 connected to the rotating plate 41, a support plate 43 for supporting the first driving unit 42 and the rotating plate 41, and a first translation unit 44 connected to the support plate 43; the lower detection mechanism 3, the left detection mechanism 4, and the right detection mechanism 5 are respectively used to detect the flatness of the lower end face, the left side face, and the right side face of the crossbeam unit 1; the lower detection mechanism 3 cooperates with the left detection mechanism 4 and the lower detection mechanism 3 cooperates with the right detection mechanism 5 to detect the verticality of the crossbeam unit 1.

[0029] The flatness of the lower end face, left side face, and right side face of the crossbeam unit 1 can be detected by setting up the conveying mechanism 2 in conjunction with the lower detection mechanism 3, the left detection mechanism 4, and the right detection mechanism 5. The lower detection mechanism 3 in conjunction with the left detection mechanism 4 and the lower detection mechanism 3 in conjunction with the right detection mechanism 5 are used to detect the verticality of the crossbeam unit 1. The use of automated detection equipment can greatly improve the detection efficiency of the crossbeam unit 1 and improve the detection accuracy of the flatness and verticality of the crossbeam unit 1, thereby ensuring the forming quality of the crossbeam unit 1.

[0030] The left detection mechanism 4 and the right detection mechanism 5 have the same structure; The upper end of the beam unit 1 in this invention is open, therefore, it is not necessary to inspect the upper end surface.

[0031] It should be noted that, in order to further improve the detection accuracy of the flatness and verticality of the beam unit 1, and at the same time avoid the problem that the original single contact detection unit 31 is easily affected by surface impurities and insufficient identification of minor deviations, the present invention adds a laser detection module 34 without changing the overall structure of the device or modifying any proprietary name and designation. This module forms a contact + non-contact dual detection collaborative mode with the original detection unit 31. The two have no structural conflict and are complementary in function, achieving full coverage of the contact detection points and laser detection points on the detection surface of the beam unit 1, with no detection blind spots. The laser detection module 34 is fixed along the length of the crossbeam unit 1 at the gap between adjacent original detection units 31; and the overall height of the laser detection module 34 is lower than the lowest end of the ball bearings 313 of the original detection unit 31, so as to ensure that when the lifting unit 33 drives the lifting plate 32 to rise and the ball bearings 313 abut against the lower end face of the crossbeam unit 1, the laser beam emitted by the laser detection module 34 can pass vertically through the gap between the ball bearings 313 and directly irradiate the lower end face of the crossbeam unit 1 without obstruction. Similarly, the original detection unit 31 is arranged vertically along the rotating plate 41, and the laser detection module 34 is fixed horizontally on the outside of the connecting rod 312 of the original detection unit 31, without exceeding the edge range of the rotating plate 41; ensuring that when the first driving unit 42 drives the rotating plate 41 to rotate around the rotating rod 45 to adjust the angle, the laser detection module 34 will not collide with the support plate 43 or the first translation unit 44, and the laser beam is always aligned with the left or right side of the crossbeam unit 1; The laser detection module 34 adopts a miniaturized integrated design, which can be adapted to the installation space of the original support carrier. No additional drive components are required. It is connected to the control module 6 only through wires or wirelessly.

[0032] While the original detection unit 31 performs preliminary detection, the laser detection module 34 is simultaneously activated: the laser emitter emits a laser beam, which is reflected by the detection surface of the crossbeam unit 1 and captured by the laser receiver. The laser ranging module calculates and transmits the distance data to the control module 6; the control module 6 focuses on analyzing the laser distance data of the "deviation point to be verified" and its surroundings. If the laser distance to the area corresponding to the "deviation point to be verified" is significantly different from that of the surrounding normal area, then it is confirmed that there is a real flatness deviation at that location, and the magnitude of the deviation is quantified by the distance difference. If the laser distance in the area corresponding to the "deviation point to be verified" is normal, the pressure abnormality of the original detection unit 31 is determined to be a misjudgment, such as the uneven force on the ball 313 caused by tiny impurities attached to the surface of the beam. The abnormal signal is automatically removed.

[0033] The control module 6 performs fusion analysis on the pressure data from the original detection unit 31 and the distance data from the laser detection module 34: Flatness judgment: If both sets of data are normal, or there is only a real deviation that can be verified by laser, the flatness test result will be output as qualified / unqualified, and the location and size of the deviation will be specified. Verticality determination: The laser detection module 34 of the lower detection mechanism 3 provides vertical distance data, and the laser detection modules 34 of the left detection mechanism 4 and the right detection mechanism 5 provide horizontal distance data. The control module 6 determines whether the verticality of the beam unit 1 is qualified based on the deviation of the angle between the two sets of laser beams from the theoretical angle of 90° and the pressure distribution uniformity of the original detection unit 31.

[0034] Furthermore, such as Figures 1-3 As shown, the conveying mechanism 2 includes three sets of first conveying components 21, second conveying components 22, and third conveying components 23 arranged side by side; the lower detection mechanism 3 is disposed between the first conveying component 21 and the second conveying component 22; the left detection mechanism 4 and the right detection mechanism 5 are disposed between the second conveying component 22 and the third conveying component 23. In this way, when the beam unit 1 moves on the conveying mechanism 2, the lower detection mechanism 3, the left detection mechanism 4, and the right detection mechanism 5 can detect the beam unit 1 in sequence, which can avoid interference between the lower detection mechanism 3 and the left detection mechanism 4 and the right detection mechanism 5, thereby improving the detection efficiency.

[0035] Furthermore, such as Figure 3 As shown, the first conveying assembly 21 includes a conveying frame 221, conveying rollers 222, a first limiting plate 223, a second limiting plate 224, and a second translation unit 225. Multiple sets of conveying rollers 222 are arranged side by side and rotatably mounted on the conveying frame 221. The first limiting plate 223 is fixedly mounted on one end of the conveying frame 221. The second limiting plate 224 is mounted on the conveying frame 221 through at least one set of second translation units 225. The first limiting plate 223 and the second limiting plate 224 are arranged parallel to each other.

[0036] In this system, the second limiting plate 224 can be moved relative to the first limiting plate 223, thereby enabling the detection of beam units 1 of different sizes.

[0037] In detail, after placing the crossbeam unit 1 on the conveying roller 222, one side of the crossbeam unit 1 is first attached to the first limiting plate 223. Then, the second translation unit 225 is controlled to work and drive the second limiting plate 224 to approach the crossbeam unit 1 so that it is attached to the other side of the crossbeam unit 1. Finally, the conveying roller 222 is controlled to rotate and the crossbeam unit 1 is conveyed forward.

[0038] It should be noted that in this embodiment, the first conveying component 21, the second conveying component 22, and the third conveying component 23 have the same structure. In this way, the space between the first conveying component 21 and the second conveying component 22, and between the second conveying component 22 and the third conveying component 23, is sufficient for the lower detection mechanism 3 or the left detection mechanism 4 and the right detection mechanism 5, so as to facilitate the subsequent detection work. Among them, multiple sets of conveyor rollers 222 achieve synchronous rotation through a motor, sprocket and chain structure, the specific structure of which will not be described in detail.

[0039] Furthermore, such as Figures 4-5As shown, the detection unit 31 includes an elastic element 311 disposed on the lifting plate 32 or the rotating plate 41, a connecting rod 312 connected to the elastic element 311, and a ball bearing 313 rotatably disposed at the end of the connecting rod 312. A pressure sensing element 314 is disposed at one end of the lifting plate 32 or the rotating plate 41 near the elastic element 311. A control module 6 is also provided on the lifting plate 32 or the support plate 43, and the control module 6 is electrically connected to the pressure sensor 314. The first drive unit 42 is fixedly mounted on the support plate 43 and the rotating shaft of the first drive unit 42 is connected to the rotating plate 41 in a transmission manner. At least one set of rotating rods 45 is provided between the rotating plate 41 and the support plate 43. The setting of the rotating rods 45 can further improve the stability of the rotating plate 41 and prevent the rotating plate 41 from sliding during operation.

[0040] When checking flatness, taking the following detection mechanism 3 as an example, during operation, the detection unit 31 and the lifting plate 32 move upward under the drive of the lifting unit 33 until the ball 313 abuts against the lower end face of the beam unit 1. Since the lower end face of the beam unit 1 is placed on the conveying roller 222, the lifting plate 32 only needs to remain parallel to the upper surface of the conveying mechanism 2. During detection, the lifting unit 33 drives the detection unit 31 to move upward until the ball 313 abuts against the lower end face of the beam unit 1 and the elastic element 311 is compressed, thereby causing the pressure sensing element 314 to receive a pressure sensing signal. The pressure sensing signal of each group of detection units 31 is transmitted to the control module 6. If the pressure sensing signal values ​​of all detection units 31 in the same row are the same, it indicates that the flatness of the lower end face of the beam unit 1 meets the requirements, and is recorded as follows: E 下 =[P1,P2...P N ] E 下 The flatness of the lower surface of beam unit 1 is represented by P, where P represents the pressure value detected by one set of detection units 31 on the lower surface of beam unit 1. If one of the points of beam unit 1 (P) N If a pit or bump appears, the pressure value (P) detected by the detection unit 31 at that location will be recorded. N The pressure value will be smaller or larger compared to other pressure values; When using the left detection mechanism 4 and the right detection mechanism 5 to detect the flatness of the side of the crossbeam, if the angle between the lower end face of the crossbeam unit 1 and the side face is 90° (that is, the verticality of the crossbeam unit 1 meets the requirements), the first translation unit 44 in the left detection mechanism 4 and the right detection mechanism 5 can be directly controlled to move, thereby driving the support plate 43 and the detection unit 31 closer to the side face of the crossbeam unit 1 for detection. The detection principle is the same as the detection principle of the lower detection mechanism 3, and will not be described in detail here. If the angle between the lower end face and the side face of beam unit 1 is not 90° (meaning the verticality of beam unit 1 does not meet the requirements), when the detection unit 31 in the left detection mechanism 4 or the right detection mechanism 5 approaches the side face of beam unit 1, the flatness E detected by the left detection mechanism 4 will be... 左 Or the flatness E detected by the right testing agency 5 右 The pressure values ​​P in the test results are no longer the same at multiple points, and the test results E 左 or E 右 The readings are either increasing or decreasing. At this point, it is necessary to control the first drive unit 42 in the left detection mechanism 4 or the right detection mechanism 5 to operate and drive the rotating plate 41 and multiple sets of detection units 31 to rotate a certain angle α until E... 左 or E 右 If the pressure values ​​P in multiple locations are the same again, the flatness of the side of the crossbeam unit 1 can be checked again. At the same time, by obtaining the rotation angle of the first drive unit 42 shaft (i.e., the rotation angle α of the rotating plate 41 and multiple sets of detection units 31), the perpendicularity deviation between the lower end face and the side face can be known, so as to facilitate the subsequent adjustment of the crossbeam unit 1.

[0041] It should be noted that the pressure sensing element 314 is a thin-film pressure sensor. Thin-film pressure sensors have high sensitivity and can detect minute pressure changes. Furthermore, the thin-film design makes it small in size and light in weight, and it has good long-term stability and repeatability, maintaining consistent performance during long-term use. To facilitate the collection of the rotation angle of the first drive unit 42 shaft, an angle sensor can be installed on the shaft. This angle sensor is electrically connected to the control module 6, and its structure will not be described in detail.

[0042] Furthermore, such as Figure 6 As shown, the detection unit 31 is provided with two rows, and the two rows of detection units 31 are arranged alternately. This arrangement can increase the contact area between the ball bearing 313 in the detection unit 31 and the surface of the crossbeam unit 1, thereby improving the accuracy of the detection results of the detection unit 31. Optionally, the detection unit 31 can also be provided with three or more rows.

[0043] Furthermore, such as Figures 7-8 As shown, a support mechanism 7 is also provided between the second conveying component 22 and the third conveying component 23, and the left detection mechanism 4 and the right detection mechanism 5 are both provided on the support mechanism 7; The support mechanism 7 includes a gantry frame 71, a second drive unit 72, a threaded rod 73, and a translation plate 74. The second drive unit 72 is fixedly installed at the lower end of the gantry frame 71; the threaded rod 73 is connected to the second drive unit 72; and the translation plate 74 is connected to the threaded rod 73 and is slidably installed at the lower end of the gantry frame 71. The left detection mechanism 4 is fixedly connected to the translation plate 74, and the right detection mechanism 5 is fixedly connected to the gantry frame 71.

[0044] The support mechanism 7, in conjunction with the left detection mechanism 4 and the right detection mechanism 5, enables the left detection mechanism 4 and the right detection mechanism 5 to detect beam units 1 of different sizes.

[0045] In detail, when the crossbeam unit 1 moves on the conveying mechanism 2, the first translation unit 44 in the right detection mechanism 5 is first controlled to work, thereby driving the detection unit 31 to abut against the right side of the crossbeam unit 1. Then, the second drive unit 72 is controlled to work, and the second drive unit 72 will drive the threaded rod 73 to rotate, thereby driving the translation plate 74 and the left detection mechanism 4 to move towards the left side of the crossbeam unit 1. Finally, the first translation unit 44 in the left detection unit 31 works, thereby driving the detection unit 31 to abut against the left side of the crossbeam unit 1.

[0046] Example 2 Components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: This invention also provides a multi-angle decorative strip 9 horizontal beam adapted to curtain wall units, such as... Figure 10 As shown, the upper end of the beam unit 1 is connected to the decorative strip 9 via an angle adapter 8; In this invention, nine profile molds are used to meet the various requirements of the decorative strip 9 in terms of horizontal angle. These decorative strips 9 are fixed at specific angles to prevent loosening or misinstallation. At the same time, by adding a horizontal decorative beam (beam unit 1), all the decorative strips 9 are connected in series and transferred to the main column to bear the force. This design not only easily solves the problem of varying vertical angles, but also does not affect the overall structure of the unitized curtain wall. Specifically, in addition to the standard vertical angle of 90°, the decorative strip 9 has as many as 9 different horizontal angles: 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80° and 90°.

[0047] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
