Plate thickness detection device based on dual laser rangefinder sensor module

Abstract

This invention provides a plate thickness detection device based on a dual-laser rangefinder sensor module. Two laser rangefinder sensors, positioned vertically opposite each other, are symmetrically arranged on a C-shaped dual-sensor mounting frame, forming a dual-laser rangefinder sensor module. A horizontal plate placement frame is placed between these two laser rangefinder sensors. The plate to be tested is placed on the plate placement frame. The first laser rangefinder sensor detects the distance from the upper surface of the plate, and the second laser rangefinder sensor detects the distance from the lower surface of the plate. The thickness of the plate is obtained by subtracting the detection distance of the first and second laser rangefinder sensors from the known installation distance between them. Furthermore, the C-shaped dual-sensor mounting frame is moved in the XY plane by a transverse and longitudinal linear electric slide, thereby achieving comprehensive detection of the thickness value at all positions of the plate.

Technical Field

[0014] The advantages and beneficial effects of this utility model are as follows:

[0015] This invention features two symmetrically arranged, vertically opposite laser rangefinders on a C-shaped dual-sensor mounting bracket, forming a dual-laser rangefinder module. A horizontal plate placement bracket is positioned between these two laser rangefinders. The plate to be tested is placed on the plate placement bracket. The first laser rangefinder detects the distance from the upper surface of the plate, and the second laser rangefinder detects the distance from the lower surface of the plate.

[0023] Frame 1 serves as the supporting foundation for the entire testing device; see Appendix. Figure 1 As a preferred embodiment, the frame structure can be as follows: Frame 1 includes two symmetrically arranged bases 11, each base having a support frame 12. Further, the support frame 12 includes six columns 121 and a rectangular frame 122 mounted on top of the columns. A transverse connecting frame 13 is provided between the bottoms of the two support frames 12 to achieve overall connection of the frame. Further, the transverse connecting frame 13 includes four crossbeams 131 arranged in a rectangular pattern. The two ends of the four crossbeams 131 are fixedly connected to the two support frames 12 respectively. Vertical connectors 132 are provided between adjacent vertically aligned crossbeams 131, and longitudinal connectors 133 are provided between adjacent longitudinally aligned crossbeams 131. Even further, after welding, the frame 1 undergoes overall stress-relief annealing, resulting in higher strength and rigidity, and increased stability during movement.

[0024] The longitudinal linear electric slide 4 is mounted on the top of one of the uprights 12 of the frame 1, and the longitudinal rail 8 is mounted on the top of the other upright 12 of the frame 1, so that the longitudinal linear electric slide 4 and the longitudinal rail 8 form a pair of parallel longitudinal sliding mounting bases.

[0025] The two ends of the transverse moving support beam 2 are respectively mounted on the longitudinal linear electric slide 4 and the longitudinal track 8, and the transverse moving support beam 2 is driven to move longitudinally by the longitudinal linear electric slide 4. Specifically, one end of the transverse moving support beam 2 is connected to the moving end of the longitudinal linear electric slide 4, and the other end of the transverse moving support beam is connected to the slider on the longitudinal track 8 through the connecting seat 21. Further details can be found in the appendix. Figure 2 The connecting seat 21 is L-shaped, including a vertical plate 211 and a horizontal plate 212 connected to the outer bottom of the vertical plate 211. A reinforcing rib plate 213 is welded between the vertical plate 211 and the horizontal plate 212. A vertical first elongated mounting hole 214 is provided on the vertical plate 211 for connecting to the end of the transverse moving support beam 2 by bolts. Through the vertical first elongated mounting hole 214, the installation height of the end of the transverse moving support beam 2 can be adjusted so that the transverse moving support beam 2 remains horizontal.

[0026] The transverse linear electric slide 3 is fixedly installed on the bottom surface of the transverse moving support beam 2. The C-type dual sensor mounting frame 6 is connected to the moving end of the transverse linear electric slide 3, and the C-type dual sensor mounting frame 6 is driven to move laterally by the transverse linear electric slide 3. The first laser ranging sensor 51 and the second laser ranging sensor 52 are symmetrically installed on the C-type dual sensor mounting frame 6 to form a dual laser ranging sensor module. The plate placement frame 7 is horizontally installed on the frame 1.

[0027] During testing, the plate to be tested is placed on the plate placement frame 7, positioned between the first laser rangefinder 51 and the second laser rangefinder 52 on the C-shaped dual-sensor mounting frame 6. The first laser rangefinder 51 detects the distance from the upper surface of the plate, and the second laser rangefinder 52 detects the distance from the lower surface of the plate. The mounting distance between the first and second laser rangefinders is fixed and known. Therefore, the thickness of the plate is obtained by subtracting the detection distances of the first and second laser rangefinders from the installation distance between them. Furthermore, during the testing process, the C-shaped dual-sensor mounting frame 6 is moved in the XY plane by the transverse linear electric slide 3 and the longitudinal linear electric slide 4, enabling comprehensive detection of the thickness value at all positions of the plate.

[0030] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0031] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0032] The above description of the present utility model is exemplary. It should be noted that, without departing from the core of the present utility model, any simple modifications, alterations, or other equivalent substitutions that can be made by those skilled in the art without creative effort fall within the protection scope of the present utility model.
