Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, and in particular to a device and method for quickly detecting the appearance and size of sound insulation felt for buildings. Background Art

[0002] Sound insulation felt for construction is a new type of flame retardant, harmless, lightweight and environmentally friendly sound insulation and vibration reduction building material. It is a flexible coil made of polymer materials, metal powders and various additives. Its common specifications are: width (1240±10) mm, length (10000±10) mm, thickness specifications (0.8, 1.0, 2.0, 3.0) mm, thickness tolerance average value ±0.10 mm, single value ±0.20 mm. Appearance quality: The surface should be flat, the edges should be neat, without cracks, holes, bonding, bubbles and scars.

[0003] The inspection of the appearance and size of building sound insulation felt is to lay the sound insulation felt flat on the ground, and then make a conclusion by manual observation and hand-held measuring tool testing after testing 3 rolls of sound insulation felt respectively and statistical calculation. Building sound insulation felt is a flexible coil. If it is not handled properly on the flat ground, its length or width is very easy to change. There are often missed inspections and misjudgments during manual observation and hand-held measuring tool testing. For example, cracks, holes, bonding, bubbles and scars on the surface are often missed, and the size measurement cannot be fully inspected without error. Since each piece of sound insulation felt has a large surface area and both sides must be tested, the labor intensity of the inspectors is also huge for the inspection institutions that receive large batches. Due to the low inspection quality and the inability to trace the inspection process, customer quality objections often occur.

[0004] How to ensure that the appearance and size inspection of sound insulation felts meet the standard requirements, prevent the omission of cracks, holes, adhesion, bubbles and scars, ensure full size measurement without errors, reduce the labor intensity of inspectors, eliminate human interference factors, and improve inspection quality and efficiency.

DETAILED DESCRIPTION

[0038] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0039] A device for quickly detecting the appearance and size of sound insulation felt for buildings comprises a transparent table top B8 supported by legs B10 and installed on the ground. In the present embodiment, the table top B8 is horizontal colorless fiberglass. Circular arcs 9 are provided at both ends of the length direction of the horizontal colorless fiberglass table top B8. The circular arcs 9 facilitate the angle change of a conveyor belt 11. The table top B8 is rotatably installed at both ends of its length direction with rollers A16 and B58 which are parallel to its width direction and driven by torque servo motors. A transparent conveyor belt 11 which is connected in a roll is wound on the roller A16. After the conveyor belt 11 is laid on the table top B8, its end is connected to the roller B58.

[0040] like Figure 1 As shown, two bases A13 are arranged on the ground 1 on the left side of the length direction of the horizontal colorless glass fiber reinforced plastic table B8. The top surfaces of the two bases A13 are fixed with shaft seats A14 by bolts. A roller A16 driven by a torque servo motor is rotatably installed on the two shaft seats A14. One end of the transparent PVC conveyor belt 11 is fixed on the outer surface of the roller A16 and wound into a roll A12. When the sound insulation felt sample 31 is tested, the roll A12 is the release end of the transparent PVC conveyor belt 11. The transparent PVC conveyor belt 11 is wound into a roll A12. The other end of the belt 11 passes through the upper surface of the horizontal colorless glass fiber reinforced plastic table B8, is fixed on the outer surface of the roller B58 and is wound into a roll B57. When the building sound insulation felt sample 31 is tested, the roll B57 is the curled end of the transparent PVC conveyor belt 11. The two ends of the roller B58 are respectively fixed on two axle seats B59, and the two axle seats B59 are respectively mounted on two bases B60. The two bases B60 are respectively fixed to the ground 1 at the right end of the length direction of the horizontal colorless glass fiber reinforced plastic table B8 through anchor bolts.

[0041] Roller A16 and roller B58 are parallel to each other. Since both are driven by torque servo motors, the tension and speed of the transparent PVC conveyor belt 11 can be well controlled, and the conveyor belt will not slip or lose its rotation. When testing the sound insulation felt sample 31, the two rotate clockwise. After the test is completed, they rotate counterclockwise to the state before starting, waiting for the next sound insulation felt sample to be tested.

[0042] When being tested, the rolled sound insulation felt sample 31 is placed on the transparent PVC conveyor belt 11, that is, located on the left side of the middle of the length direction of the colorless fiberglass table B8. The width of the sound insulation felt sample 31 is smaller than the width of the transparent PVC conveyor belt 11, the width of the transparent PVC conveyor belt 11 is smaller than the width of the horizontal colorless fiberglass table B8, and the length of the transparent PVC conveyor belt 11 is much larger than the length of the sound insulation felt sample 31.

[0043] A table A7 is arranged directly below the middle of the table B8 and is mounted on the ground via legs A6. A contour measuring instrument A2, an AI image recognition sensor A5 and a light-emitting tube 4 are respectively installed on the surface of the table A7. Vertical poles 3 are respectively installed vertically upward on both sides of the table A7 and are located on both sides of the length direction of the table B8. Two laser displacement sensors B63, whose minimum height is flush with the upper surface of the table B8, are respectively installed on the opposite surfaces of the two vertical poles 3.

[0044] A top plate 17 supported by columns 15 and installed on the ground is arranged directly above the table B8, and an AI image recognition sensor C33, a laser displacement sensor A34, a contour measuring instrument B36 and two color sensors 35 are respectively installed in the area of ​​the bottom surface of the top plate 17 facing the table A7; an unwinding clamping mechanism for positioning the sound insulation felt roll when unwinding and a rewinding clamping mechanism for positioning the sound insulation felt roll when rewinding after unwinding are respectively installed on the bottom surface of the top plate 17 above the table B8 and on both sides of the table A7.

[0045] In order to realize the automatic detection of the sound insulation felt, the detection device of the present invention also includes a display PLC controller 61, which is electrically connected to the torque servo motor, the unwinding clamping mechanism, the winding clamping mechanism, the contour measuring instrument A2, the contour measuring instrument B36, the AI ​​image recognition sensor A5, the AI ​​image recognition sensor C33, the laser displacement sensor A34, the laser displacement sensor B63, the light-emitting tube 4 and the two color sensors 35.

[0046] The unwinding clamping mechanism includes at least one pressure roller A16 respectively arranged on both sides of the length direction of the sound insulation felt roll. In this embodiment, two pressure rollers A30 are respectively arranged on both sides of the radial direction of the columnar body of the rolled sound insulation felt sample 31 to be tested placed on the transparent PVC conveyor belt 11. The pressure roller A30 plays a dynamic positioning role for the columnar sound insulation felt sample 31 to be tested. Both ends of each pressure roller are equipped with rolling bearings, and the inner ring of the rolling bearing is equipped with a shaft. Both ends of each pressure roller A16 on each side are rotatably installed on an axis frame A29, and the axis frame A29 is respectively fixed on the connecting plate A28. The back center of the connecting plate A28 is vertically welded to the optical axis A24. A retaining ring 23 is provided at one end of the shaft A24 away from the connecting plate A28, a sliding sleeve A26 is slidably sleeved on the optical axis A24, a compression spring B27 is sleeved on the optical axis 24 between the sliding sleeve A26 and the connecting plate A28, and a compression spring A25 is sleeved on the optical axis A24 between the sliding sleeve A26 and the retaining ring 23. Cantilever plates A64 are welded to the relative outer walls of each pair of sliding sleeves A26, and a U-shaped frame A66 is hinged on the cantilever plate A64. Each U-shaped frame A66 is connected to the top plate 17 through a two-axis telescopic mechanism A; and two AI image recognition sensors B32 are also provided on the bottom surface of the top plate 17 just above the sound insulation felt roll. The two AI image recognition sensors B32 are used to monitor the position change of the columnar sound insulation felt sample 31 to be detected. The PLC controller 61 is displayed to control the operation of the four servo electric cylinders A20 and B18, so that the four pressure rollers A30 can reasonably block the columnar sound insulation felt sample 31, so that the outer end of the columnar sound insulation felt sample 31 is laid flat on the moving transparent PVC conveyor belt 11.

[0047] The two-axis telescopic mechanism A includes a servo electric cylinder A20 vertically fixed to the bottom surface of the top plate 17. The telescopic end A19 of the servo electric cylinder A20 is connected to a servo electric cylinder B21 which forms an obtuse angle with the servo electric cylinder A20 through a connecting block A18. The telescopic end B65 of the servo electric cylinder B21 is connected to a U-shaped frame B69.

[0048] When the flat sound insulation felt sample 31 is about to reach the middle detection section 62 of the horizontal colorless fiberglass table B8, the AI ​​image recognition sensor C33 installed on the lower surface of the top plate 17 begins to identify whether there are cracks, adhesion, bubbles, scars and other quality conditions on the upper surface of the sound insulation felt sample 31. The AI ​​image recognition sensor A5 set on the table A7 also begins to identify the quality of the lower surface of the sound insulation felt sample 31. The AI ​​image recognition sensors A5 and C33 transmit the recognized image data to the display PLC controller 61 in real time, and the display PLC controller 61 marks the defect position coordinates according to the programming.

[0049] A laser displacement sensor A34, a color sensor 35 and a profile measuring instrument B36 are also installed on the lower surface of the top plate 17 above the detection section 62, wherein the laser displacement sensor A34 detects the moving speed and total length of the sound insulation felt sample 31, the color sensor 35 cooperates with the light-emitting tube 4 to detect whether there are holes on the sound insulation felt sample 31, the profile measuring instrument B36 detects whether the upper surface of the sound insulation felt sample 31 is flat and the edges are neat, and the profile measuring instrument A2 detects whether the lower surface of the sound insulation felt sample 31 is flat and the edges are neat. The laser displacement sensors B3 arranged on the vertical poles 3 on both sides of the width direction of the sound insulation felt sample 31 are used to detect the thickness of the sound insulation felt sample 31, including the detection of its full-length thickness.

[0050] The test results of the detection components such as the laser displacement sensor B3, laser displacement sensor A34, profile measuring instrument A2, profile measuring instrument B36, color sensor 35, AI image recognition sensor C33 are transmitted in real time to the display PLC controller 61. The display PLC controller 61 marks the defect position coordinates according to the programming and finally makes a detection conclusion.

[0051] The winding and clamping mechanism includes at least one pressure roller B50 respectively arranged on both sides of the end of the sound insulation felt roll, and both ends of each pressure roller B50 on each side are rotatably installed on an axis frame B, and the axis frame B49 is respectively fixed on the connecting plate B48. The optical axis B45 is vertically welded to the center of the back of the connecting plate B48, and a retaining ring B43 is arranged at the end of the optical axis B45 away from the connecting plate B48. A sliding sleeve B46 is slidably sleeved on the optical axis B45, and a compression spring D47 is sleeved on the optical axis B45 between the sliding sleeve B46 and the connecting plate B48. A compression spring C44 is sleeved on the optical axis B45 between the sliding sleeve B46 and the retaining ring B43. Cantilever plates B68 are respectively welded on the relative outer walls of each pair of sliding sleeves B46, and a U-shaped frame B69 is hinged on the cantilever plate B68. Each U-shaped frame B69 is connected to the top plate 17 through a two-axis telescopic mechanism B; it also includes two AI image recognition sensors D55 arranged on the bottom surface of the top plate 17 just above the sound insulation felt roll.

[0052] The two-axis telescopic mechanism B includes a servo electric cylinder C39 vertically fixed to the bottom surface of the top plate 17. The telescopic end C38 of the servo electric cylinder C39 is connected to a servo electric cylinder D40 at a right angle to the servo electric cylinder C39 through a connecting block B37. The telescopic end D41 of the servo electric cylinder D40 is connected to a U-shaped frame B69.

[0053] It also includes a winding guide mechanism vertically connected to the bottom surface of the top plate 17 and located between the pressure rollers B50 on both sides. The winding guide mechanism includes a semi-circular plate 54 arranged parallel to the pressure roller B50. Teeth B71 are formed on the outer walls of the semi-circular plate 54 at both ends in the length direction. Arc-shaped slide grooves 77 are also provided at both ends of the length direction. Connecting blocks C53 are slidably connected in the two arc-shaped slide grooves 77 through arc-shaped sliders 76. Each connecting block C53 is connected to the telescopic end E52 of the servo electric cylinder E51 vertically connected to the bottom surface of the top plate 17 and located directly above it. A shaft A72 is rotatably installed between the connecting blocks C53 at both ends of each semi-circular plate 54, and gears A73 that mesh with the teeth B71 are installed on the shaft A72. A servo motor A74 that drives the shaft A72 to rotate is installed on one of the connecting blocks C53.

[0054] When the outer end of the sound insulation felt sample 31 moves to the right of the middle of the horizontal colorless glass fiber reinforced plastic table B8 and contacts the inner wall of the semicircular arc plate 54, the end of the sound insulation felt sample 31 will be in a state of warping 78, see the attached Figure 8 The inner wall of the semicircular plate 54 is smooth. When the servo motor A74 works and the shaft A72 rotates, the gear A73 fixed on the shaft A72 engages with the tooth B71 to rotate the semicircular plate 54 in the opposite direction. When the end of the sound insulation felt sample 31 contacts the inner wall of the semicircular plate 54, it will gradually rise 78 and bend along the inner wall. At the same time, the servo motor A74 works to make the semicircular plate 54 and the end of the sound insulation felt sample 31 rise 78 and rotate synchronously to the maximum state of the "lower opening". See the attached Fig. 9 , and then the semicircular arc plate 54 moves up, and at the same time, the left and right pressure rollers B50 contact and press the end of the sound insulation felt to curl 79 and continue to curl until all curling is completed.

[0055] The top of each connection block C53 is connected to the telescopic end E52 of a servo electric cylinder E51, and the servo electric cylinder E51 is fixed to the lower surface of the top plate 17 by bolts.

There are two AI image recognition sensors D55 on the lower surface of the top plate 17, and the two AI image recognition sensors D55 are located on the left and right sides of the servo electric cylinder E51. The AI ​​image recognition sensors D55 are used to monitor the changing contact between the end of the sound insulation felt sample 31 and the semicircular arc plate 54 and the pressure roller B50 and the curled end 56 of the sound insulation felt coil.

After the end of the sound insulation felt moves and contacts the inner wall of the semicircular plate of the winding guide mechanism, the AI ​​image recognition sensor C and the AI ​​image recognition sensor D recognize that the end of the sound insulation felt is in a warped state, and the servo motor A drives the semicircular plate to rotate along with the warped part of the sound insulation felt until the end of the sound insulation felt is in a curled state, and the telescopic end E of the servo electric cylinder E moves upward to drive the semicircular plate to move upward synchronously, and the four servo electric cylinders C and D drive the pressure roller B to contact and press the sound insulation felt until the sound insulation felt is rolled up, completing the full-length appearance and size inspection of a roll of sound insulation felt and completing its winding;

[0060] S4. Repeat the above steps to complete the appearance and size inspection of other sound insulation felt rolls.

[0061] The device utilizes the movement of the transparent PVC conveyor belt 11 to lay the sound insulation felt sample 31 flat on the transparent PVC conveyor belt 11 without any pulling force, so that the sample damage and deformation caused by manual pulling and throwing of the sound insulation felt sample in the past will not occur. A rolling bearing is arranged between the pressure roller and the shaft in the device, so when the pressure roller contacts the rolled sound insulation felt sample 31, there is rolling friction and no pulling problem. Due to the use of the transparent PVC conveyor belt 11 and the horizontal colorless fiberglass table B8, the detection under the sound insulation felt sample 31 is also realized. The AI ​​image recognition sensor, laser displacement sensor, color sensor, contour measuring instrument and servo control and other devices are used to realize the automatic detection of the appearance and size of the sound insulation felt sample without leakage, reduce labor intensity, eliminate human interference factors, and improve detection quality and efficiency.
