When performing detection work, it is necessary for the staff to manually position the particleboard, which is very troublesome and has low efficiency. If no positioning is carried out, the position and range of the defects cannot be accurately determined, affecting the accuracy of the detection results. Therefore, it is necessary to design a surface defect detection device for particleboard to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a surface defect detection device for particleboard is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A particleboard surface defect detection device includes a conveyor. A first U-shaped frame is fixedly connected to the top of the conveyor. A cylinder is fixedly connected to the top of the first U-shaped frame. The output end of the cylinder is fixedly connected to a mounting plate. A cleaning mechanism is arranged at the bottom of the mounting plate. First square grooves are formed at both ends of the mounting plate. Two fixing plates are fixedly connected to both sides of the mounting plate. At the same end, the two fixing plates are fixedly connected to the same round rod on the side close to each other. A side plate is sleeved on the round rod. An inclined groove is formed on the side plate. The inclined groove is adapted to the round rod. The round rod is arranged in the inclined groove and is slidably connected to the side plate. Guide grooves are formed at the tops of the two side plates. Guide plates are arranged in the guide grooves and are slidably connected to the side plates. The guide plates are fixedly connected to the first U-shaped frame. The bottoms of the two side plates are fixedly connected to a connecting plate on the side close to each other. At the bottom of the two connecting plates on the side close to each other, a U-shaped plate is fixedly connected. A number of rollers are equidistantly distributed on the U-shaped plate. Since the technical means of adopting a descending cleaning mechanism and at the same time moving the rollers on both sides closer to the particleboard are used, when the rollers continue to move after contacting the particleboard, the particleboard can be aligned and positioned, effectively solving the problem in the background technology that there is a lack of a mechanism for positioning the particleboard. During the detection work, it is necessary for the staff to manually position the particleboard, which is very troublesome and has low efficiency. If no positioning is carried out, the position and range of the defect cannot be accurately determined, affecting the accuracy of the detection result. Furthermore, it realizes the technical effect of facilitating the positioning of the particleboard, reducing the work burden of the staff, ensuring the accuracy of the detection result, and improving the efficiency of the detection work.

[0011] As a further solution of the present utility model, a third U-shaped frame is fixedly connected to the top of one end of the conveyor far from the second U-shaped frame and the first U-shaped frame, and a camera is arranged at the bottom of the third U-shaped frame.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In the present utility model, due to the technical means of adopting the descending cleaning mechanism and simultaneously moving the rollers on both sides closer to the particle board, if the rollers continue to move after contacting the particle board, the particle board can be straightened and positioned, effectively solving the problem in the background technology that there is a lack of a mechanism for positioning the particle board. When performing the detection work, it is necessary for the staff to manually position the particle board, which is very troublesome and has low efficiency. If no positioning is carried out, the position and range of the defect cannot be accurately determined, affecting the accuracy of the detection result. Furthermore, the technical effect of facilitating the positioning of the particle board, reducing the work burden of the staff, ensuring the accuracy of the detection result, and improving the efficiency of the detection work is achieved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

A cylinder 3 is fixedly connected to the top of the first U-shaped frame 2. The output end of the cylinder 3 is fixedly connected to a mounting plate 4. A cleaning mechanism is arranged at the bottom of the mounting plate 4. First square grooves 5 are opened at both ends of the mounting plate 4. Two fixing plates 6 are fixedly connected to both sides of the mounting plate 4. At the side close to each other of the two fixing plates 6 at the same end, the same round rod 7 is fixedly connected. A side plate 8 is sleeved on the round rod 7. An inclined groove 9 is opened on the side plate 8. The inclined groove 9 is adapted to the round rod 7. The round rod 7 is arranged in the inclined groove 9. The round rod 7 is slidably connected to the side plate 8. Guide grooves 11 are opened at the tops of the two side plates 8. A guide plate 10 is arranged in the guide grooves 11. The guide plate 10 is slidably connected to the side plate 8. The guide plate 10 is fixedly connected to the first U-shaped frame 2. At the side close to each other of the bottoms of the two side plates 8, connecting plates 12 are fixedly connected. At the bottom of the ends close to each other of the two connecting plates 12, U-shaped plates 13 are fixedly connected. A number of rollers 14 are equidistantly distributed on the U-shaped plates 13. Since the technical means of using a downward cleaning mechanism and at the same time moving the rollers on both sides closer to the particleboard are adopted, when the rollers continue to move after contacting the particleboard, the particleboard can be aligned and positioned, effectively solving the problem in the background art that there is a lack of a mechanism for positioning the particleboard. When performing the detection work, it is necessary for the staff to manually position the particleboard, which is very troublesome and has low efficiency. If no positioning is carried out, the position and range of the defect cannot be accurately determined, affecting the accuracy of the detection result. Furthermore, the technical effect of facilitating the positioning of the particleboard position, reducing the work burden of the staff, ensuring the accuracy of the detection result, and improving the efficiency of the detection work is achieved.

[0022] In this embodiment, second square grooves 15 are opened at both ends of the first U-shaped frame 2. The side plates 8 are arranged in the second square grooves 15.

[0023] In this embodiment, the cleaning mechanism includes two fixing seats 16. The fixing seats 16 are fixedly connected to the mounting plate 4. One side of one of the fixing seats 16 is fixedly connected to a motor 18. The same cleaning roller 17 is rotatably connected to both fixing seats 16. The output shaft of the motor 18 is fixedly connected to the cleaning roller 17. By providing the cleaning mechanism, the surface of the particle board can be cleaned, and dust, wood chips and other impurities on the surface of the particle board can be removed, so as to avoid the influence of dust, wood chips and other impurities on the accuracy of the test results.

[0024] In this embodiment, a dust suction head 19 is fixedly connected to the bottom of the mounting plate 4, and a dust suction machine 20 is fixedly connected to the top of the mounting plate 4. The dust suction machine 20 is connected to the dust suction head 19 through a pipeline.

[0025] In this embodiment, a second U-shaped frame 21 is fixedly connected to the top of the conveyor 1, and a laser scanner 22 is arranged at the bottom of the second U-shaped frame 21.

[0026] In this embodiment, a third U-shaped frame 23 is fixedly connected to the top of the conveyor 1 at one end far from the second U-shaped frame 21 and the first U-shaped frame 2, and a camera 24 is arranged at the bottom of the third U-shaped frame 23.

[0027] Working principle: When using this device, the particleboard to be detected can be placed on the conveyor belt of conveyor 1, and then conveyor 1 is started by the PLC to move the particleboard. Subsequently, cylinder 3 can be started, and the output end of cylinder 3 will drive the mounting plate 4 to descend. The mounting plate 4 will drive the fixing plate 6 to descend along the second square groove 15, which can prevent the mounting plate 4 from shifting during movement. When the mounting plate 4 descends, it will drive the fixed seat 16 to descend. The fixed seat 16 will drive the cleaning roller 17 and the motor 18 to descend, so that the cleaning roller 17 descends close to the particleboard. When the bristles on the cleaning roller 17 contact the particleboard, the motor 18 can be started. The output shaft of the motor 18 will drive the cleaning roller 17 to rotate to clean the particleboard, removing dust, wood chips, etc. on the surface of the particleboard. At the same time, the dust collector 20 is started, and the dust and wood chips can be sucked into the dust suction head 19 and finally into the dust collector 20, preventing the dust and wood chips from flying. Cleaning the particleboard can also ensure the accuracy of the detection results and avoid the influence of dust and wood chips on the detection results during defect detection. When the fixing plate 6 descends, it can also drive the round rod 7 to descend. The round rod 7 will move along the inclined groove 9, and the round rod 7 will squeeze the side plates 8 to make the two side plates 8 approach each other. When the side plates 8 move, they will move along the guide plate 10. Through the mutual cooperation of the guide plate 10 and the guide groove 11, the side plates 8 will not shift during movement. When the two side plates 8 approach each other, they will drive the connecting plate 12 to move. The connecting plate 12 will drive the U-shaped plate 13 to move. The U-shaped plate 13 will drive the roller 14 to move close to the particleboard, so as to align and position the particleboard, preventing the position of the particleboard from shifting during cleaning and detection. When the particleboard moves past the laser scanner 22, the laser scanner 22 quickly scans the laser beam on the material surface to obtain surface topography data. The scanned laser reflection signal can show the flatness, undulation, and microscopic structure of the material surface. The laser scanner 22 can convert the scanned data into a digital surface image or three-dimensional graph for easy analysis and identification of surface defects. When the particleboard moves past the camera 24, the camera 24 can take a surface image, and it is easy to find the defects on the surface of the particleboard from the photo. Analysis can also be carried out through image processing software. Continuing to operate conveyor 1 can remove the particleboard, and then the detection work of the surface defects of the particleboard can be continued.
