DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Please refer to Figures 1-8 An embodiment of the present application is: a green building new material detection device for building, which comprises a workbench 1, the bottom surface of the workbench 1 is fixed with supporting legs, the upper surface of the workbench 1 is fixed with a supporting plate, the bottom surface of the supporting plate is fixed with a telescopic rod, the bottom surface of the telescopic rod is fixed with a laser scanning device 2, the laser scanning device 2 is slidingly connected to the side wall of the supporting plate, the laser scanning device 2 detects the surface flatness of the material to be detected, the back surface of the workbench 1 is fixed with a supporting table, the upper surface of the supporting table is fixed with an air cylinder 3, the material to be detected is placed on the workbench 1, the air cylinder 3 is started, the front surface of the air cylinder 3 is connected with a piston rod through a piston, the end of the piston rod away from the air cylinder 3 is fixed with a push plate 4, the air cylinder 3 pushes the push plate 4 to slide through the piston rod, and the material to be detected is pushed to move, the bottom surface of the workbench 1 is fixed with an operation bin 5, and the operation bin 5 is provided with a positioning device for conveniently positioning the material to be detected.

[0021] The positioning device includes a top rod 61, a connecting rod 62, a return spring 63, a hinge rod 64, a sliding block 65, a positioning rod 66, a tension spring 67, a positioning block 68, and a fixing rod 69. The top rod 61 passes through the worktable 1 and is slidably connected at the point of penetration. When the material to be tested is placed on the upper surface of the worktable 1, the material pushes the top rod 61 downward to slide. The connecting rod 62 is fixedly connected to the bottom end of the top rod 61 and passes through the operating chamber 5, and is slidably connected at the point of penetration. When the top rod 61 slides downward, it pushes the connecting rod 62 downward to slide as well. One end of the return spring 63 is fixedly connected to the bottom surface of the connecting rod 62, and the other end of the return spring 63 is fixedly connected inside the operating chamber 5. When the connecting rod 62 slides downwards, it compresses the return spring 63. The hinge rod 64 is hinged to the side wall of the connecting rod 62. When the connecting rod 62 slides downwards, it drives the hinge rod 64 to rotate. The end of the hinge rod 64 away from the connecting rod 62 is hinged to the side wall of the sliding block 65. The sliding block 65 is slidably connected to the bottom surface of the worktable 1. The rotation of the hinge rod 64 drives the sliding block 65 to slide closer to the connecting rod 62. The positioning rod 66 passes through the worktable 1 and is slidably connected at the point of penetration. The tension spring 67 is fixedly connected to the side wall of the positioning rod 66. When the positioning rod 66 is limited by the sliding block 65, the tension spring 67 is always in a stretched state. The positioning block 68 is fixedly connected. At the end of the tension spring 67 furthest from the positioning rod 66, when the sliding block 65 slides to disengage from the positioning rod 66, the positioning rod 66 is no longer limited by the sliding block 65, and at the same time, it is subjected to the restoring tension of the tension spring 67, sliding towards the positioning block 68. The positioning rod 66 exposed on the worktable 1 pushes the material to be tested towards the push plate 4, aligning the material to be tested with the push plate 4. The fixing rod 69 is fixedly connected to the bottom surface of the worktable 1, passing through the positioning block 68, and is slidably connected at the point of penetration. When the positioning rod 66 is released from its limit, the top rod 61 pushes the connecting rod 62 to continue moving downward. When the connecting rod 62 moves to the upper surface of the bottom end of the positioning rod 66, it pushes the positioning rod 66. The positioning rod 66 also slides downwards. When the positioning rod 66 slides downwards, the positioning block 68 also slides downwards through the tension spring 67, so that the positioning rod 66 no longer protrudes from the worktable 1. When the material to be tested is placed on the worktable 1, the positioning device, in conjunction with the top rod 61, connecting rod 62, return spring 63, hinge rod 64 and sliding block 65, releases the limitation on the positioning rod 66. When the positioning rod 66 is subjected to the elastic force of the tension spring 67, it pushes the material to be tested to slide towards the push plate 4, thereby aligning with the push plate 4. This facilitates the subsequent movement of the material to be tested for laser detection, solving the problem that the material to be tested was not aligned and corrected when placed on the worktable 1, resulting in data errors during detection. After the alignment correction of the material to be detected, cooperate with the ejector rod 61, connecting rod 62, tension spring 67, positioning block 68 and fixed rod 69 to retract the positioning rod 66, avoid the positioning rod 66 in front of the material to be detected to hinder, thereby affecting the push plate 4 to push the material to be detected to move detection, resulting in incomplete detection data, solve the problem of positioning rod 66 affecting the movement detection of the material to be detected, resulting in large detection data error.

[0022] When the embodiment works: place the material to be detected on the workbench 1, start the cylinder 3, make the cylinder 3 push the push plate 4 to slide through the piston rod, push the material to be detected to move, and then detect the surface flatness of the material to be detected through the laser scanning device 2.

[0023] When the material to be detected is placed on the surface of the workbench 1, the material to be detected pushes the ejector rod 61 to slide downward, and the ejector rod 61 slides downward to push the connecting rod 62 to slide downward and compress the return spring 63. When the connecting rod 62 slides downward, it drives the hinge joint of the hinge rod 64 and the connecting rod 62 to move downward, and the other end of the hinge rod 64 away from the connecting rod 62 is hinged with the sliding block 65, and the sliding block 65 is slidingly connected to the bottom surface of the workbench 1, so that the hinge joint of the hinge rod 64 and the sliding block 65 is not changed in position in the vertical direction. When the hinge joint of the hinge rod 64 and the connecting rod 62 moves downward, the hinge rod 64 also rotates itself, driving the sliding block 65 to slide towards the connecting rod 62. When the sliding block 65 slides away from the positioning rod 66, the positioning rod 66 is no longer limited by the sliding block 65, and at the same time, it is pulled by the tension spring 67 to restore the tension and slide towards the positioning block 68. The exposed positioning rod 66 on the workbench 1 pushes the material to be detected to move towards the push plate 4, so that the material to be detected is aligned with the push plate 4. When the positioning rod 66 is released, the ejector rod 61 pushes the connecting rod 62 to continue to move downward. When the connecting rod 62 moves to the upper surface of the bottom end of the positioning rod 66, it pushes the positioning rod 66 to slide downward. When the positioning rod 66 slides downward, the positioning block 68 is driven by the tension spring 67 to slide downward, so that the positioning rod 66 is no longer exposed to the workbench 1.

[0024] Please refer to Figures 1-8On the basis of the above-mentioned embodiment, in another embodiment of the present application, the operation bin 5 is provided with a buffer device for avoiding damage to the material by the positioning device, the buffer device comprising a limiting spring 71, a limiting block 72, a limiting plate 73, a swing rod 74, an arc-shaped spring rod 75 and a rubber ball 76, one end of the limiting spring 71 being fixedly connected to a protrusion on the outer wall of the operation bin 5, the limiting block 72 being fixedly connected to the other end of the limiting spring 71, when the connecting rod 62 slides downward to the limiting block 72, the limiting block 72 is pushed to slide away from the connecting rod 62, and at the same time, the limiting spring 71 is compressed, when the connecting rod 62 continues to slide downward to be separated from the limiting block 72, the limiting block 72 is pushed to slide away from the limiting spring 71 by the restoring force of the limiting spring 71, and the two limiting blocks 72 are close to each other to the side edge to limit the connecting rod 62, the limiting plate 73 is fixedly connected to the bottom surface of the sliding block 65, and when the sliding block 65 slides to the connecting rod 62, the limiting plate 73 is also moved, the swing rod 74 is hinged to the side wall of the positioning rod 66, one end of the arc-shaped spring rod 75 is fixedly connected to the side wall of the swing rod 74, the arc-shaped spring rod 75 is always in a compressed state, the limiting plate 73 is moved to be separated from the swing rod 74, and the swing rod 74 is no longer limited, the other end of the arc-shaped spring rod 75 is fixedly connected to the side wall of the positioning rod 66, the rubber ball 76 is fixedly connected to the end of the swing rod 74 away from the positioning rod 66, the swing rod 74 is rotated around the hinge point of the swing rod 74 and the positioning rod 66 by the restoring force of the arc-shaped spring rod 75, and the rubber ball 76 is also rotated, when the rubber ball 76 is rotated to be close to the connecting rod 62, the rubber ball 76 is increased in friction with the connecting rod 62 by the pushing force of the swing rod 74, when the connecting rod 62 is slid downward by the gravity of the material to be detected, the connecting rod 62 is limited by the limiting spring 71 and the limiting block 72, so that the connecting rod 62 is prevented from being bounced upward by the elastic force of the restoring spring 63 when it slides to the bottom end, and the material to be detected is prevented from being impacted or lifted, so that the material to be detected is prevented from being displaced in the vertical direction during laser detection, and the problem that the detection data is inaccurate due to the displacement of the material to be detected in the vertical direction during laser detection is solved. When the material to be detected is aligned with the push plate 4, the limiting plate 73, the swing rod 74, the arc-shaped spring rod 75 and the rubber ball 76 are used to apply a friction force to the connecting rod 62, so as to reduce the sliding speed of the positioning rod 66, and prevent the positioning rod 66 from sliding too fast when the limiting is released, and from impacting the material to be detected, so as to prevent the material to be detected from being damaged and affecting the detection data.

[0025] The operating chamber 5 is equipped with a limiting device to assist in limiting the movement of the material to be tested. This limiting device includes a pressing plate 81, a sliding seat 82, a positioning post 83, a support spring 84, a moving plate 85, a sliding rod 86, a clamping plate 87, a pressing block 88, a push rod 89, and a resistance block 810. The pressing plate 81 is fixedly connected to the bottom surface of the push plate 4. When the push plate 4 pushes the material to be tested, it also drives the pressing plate 81 to slide forward. The sliding seat 82 is slidably connected to the bottom surface of the inner wall of the operating chamber 5. The positioning post 83 is fixedly connected to the upper surface of the sliding seat 82. The support spring 84 is fixedly connected to the upper surface of the sliding seat 82. The moving plate 85 is fixedly connected to the end of the support spring 84 away from the sliding seat 82. When the moving plate 85 slides, it... The sliding seat 82 slides, the positioning post 83 passes through the moving plate 85 and is slidably connected at the penetration point. When the extrusion plate 81 slides to the moving plate 85, it pushes the moving plate 85 towards the center of the worktable 1. The sliding rod 86 is fixedly connected to the upper surface of the sliding seat 82, passes through the moving plate 85 and is slidably connected at the penetration point, and passes through the worktable 1 and is slidably connected at the penetration point. The clamping plate 87 is fixedly connected to the end of the sliding rod 86 away from the sliding seat 82. When the moving plate 85 slides, it also drives the clamping plate 87 to slide. The two sets of clamping plates 87 move closer to each other to limit the material to be tested. The extrusion block 88 passes through the clamping plate 87 and is slidably connected at the penetration point. When the extrusion block 88 contacts the material to be tested... The extrusion block 88 is stationary relative to the worktable 1. At this time, the clamping plate 87 continues to slide towards the center of the worktable 1, and the extrusion block 88 slides away from the center of the worktable 1 relative to the clamping plate 87. The push rod 89 is fixedly connected to the upper surface of the moving plate 85. The push rod 89 passes through the worktable 1 and is slidably connected at the point of penetration. When the extrusion block 88 slides to the push rod 89, it pushes the push rod 89 downward. The push rod 89 drives the moving plate 85 to slide downward as well, and at the same time compresses the support spring 84. When the side wall of the extrusion block 88 facing the center of the worktable 1 is flush with the side wall of the clamping plate 87 facing the center of the worktable 1, the push rod 89 pushes the moving plate 85 away from the extrusion plate 81. At this time, the extrusion plate 81 continues to slide forward and will not push further. The movable plate 85 slides, and the resistance block 810 is fixedly connected to the side wall of the movable plate 85. When the movable plate 85 slides downward, it also drives the resistance block 810 to move downward, so that the resistance block 810 fits against the inside of the operating chamber 5 and fixes the limiting device. When the push plate 4 pushes the material to be tested to move for laser detection, the limiting device, together with the extrusion plate 81, sliding seat 82, positioning column 83, support spring 84, movable plate 85 and sliding rod 86, drives the clamping plate 87 to move closer to each other, clamping and positioning the material to be tested, so that the push plate 4 will not deviate when pushing the material to be tested to move, avoiding deviation that would cause errors in the laser detection data, and solving the problem of large errors when the push plate 4 pushes the material to be tested to move for detection. When clamping and positioning the material to be detected, the matching extrusion block 88, the push rod 89 and the resistance block 810 release the connection between the extrusion plate 81 and the moving plate 85, stop when the clamping plate 87 contacts the material to be detected, and fix the clamping plate 87, so as to avoid the clamping plate 87 continuously applying pressure to the material to be detected from both sides, causing the material to be deformed, or the clamping plate 87 being affected by the movement of the material to be detected and sliding outward, causing positioning failure, solving the problem that the material to be detected may be deformed by continuous pressure, causing errors in detection data.

[0026] When the connecting rod 62 slides downward to the limiting block 72, the side edge of the connecting rod 62 slides with the inclined surface of the limiting block 72, pushes the limiting block 72 to slide away from the connecting rod 62, and extrudes the limiting spring 71. When the connecting rod 62 continues to slide downward to disengage from the limiting block 72, the limiting block 72 slides away from the limiting spring 71 under the restoring force of the limiting spring 71, and the two groups of limiting blocks 72 approach each other to the side edge to limit the connecting rod 62. When the sliding block 65 slides toward the connecting rod 62, the limiting plate 73 also moves, and the limiting plate 73 moves away from the swing rod 74 to no longer limit the swing rod 74. At the same time, the swing rod 74 is pushed by the restoring force of the arc-shaped spring rod 75 to rotate around the hinge point of the swing rod 74 and the positioning rod 66, and the rubber ball 76 also rotates. When the rubber ball 76 rotates to the side edge of the connecting rod 62, the rubber ball 76 is pushed by the swing rod 74 to increase the friction between the rubber ball 76 and the connecting rod 62.

[0027] When the push plate 4 pushes the material to be detected to move, the extrusion plate 81 is also pushed to slide forward. When the extrusion plate 81 slides to the moving plate 85, the inclined surface of the extrusion plate 81 and the side of the moving plate 85 slide with each other. The extrusion plate 81 pushes the moving plate 85 to slide to the center of the workbench 1. The sliding rod 86 penetrates through the moving plate 85 and is fixedly connected with the clamping plate 87 and the sliding seat 82. Therefore, when the moving plate 85 slides, the sliding seat 82 and the clamping plate 87 also slide. The two groups of clamping plates 87 approach each other to limit the material to be detected. When the extrusion block 88 contacts the material to be detected, the extrusion block 88 is stationary relative to the workbench 1. At this time, the clamping plate 87 continues to slide to the center of the workbench 1. The extrusion block 88 slides away from the center of the workbench 1 relative to the clamping plate 87. When the extrusion block 88 slides to the push rod 89, the side of the extrusion block 88 and the inclined surface of the push rod 89 slide with each other. The extrusion block 88 pushes the push rod 89 to slide downward. The push rod 89 drives the moving plate 85 to also slide downward and compresses the supporting spring 84. When the side wall of the extrusion block 88 facing the center of the workbench 1 is flush with the side wall of the clamping plate 87 facing the center of the workbench 1, the push rod 89 pushes the moving plate 85 to separate from the extrusion plate 81. At this time, the extrusion plate 81 continues to slide forward and will not push the moving plate 85 to slide again. When the moving plate 85 slides downward, the resistance block 810 also moves downward to make the resistance block 810 fit with the inside of the operation bin 5 and fix the limiting device.

[0028] Although the embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
