Description

Technical Field

[0001] The present invention relates to the field of practical detection, and in particular to a multifunctional intelligent detection device for machine vision. Background Art

[0002] Visual inspection refers to the process of analyzing and identifying objects, images or videos using machine vision technology. It simulates and imitates the human visual system in order to understand, analyze and process what is observed. The main purpose of visual inspection is to detect defective products and automatically screen out defective products, thereby improving production efficiency and product quality; In the existing technology, in the process of visual inspection of the surface of the board, accurately capturing its texture details and identifying defects and burrs are crucial links. However, the challenge faced by the current technology is that during the storage and production of solid wood boards, dust and other fine particles are often inevitably attached to their surfaces. If the presence of these foreign substances is not effectively handled, it will directly interfere with the accuracy of the visual inspection system and thus have a misleading effect on the inspection results. Therefore, exploring and implementing effective dust cleaning and prevention measures to ensure the purity of the inspection process and the reliability of the results has become a key issue that needs to be solved urgently.

[0005] Preferably, a plurality of light-shielding baffles are installed on the left and right sides of the U-shaped frame, and the light-shielding baffles are used to reduce interference of external light on detection and improve the detection effect.

[0006] Preferably, the cleaning mechanism comprises a cleaning roller rotatably connected between the front and rear inner walls of the U-shaped frame, and a plurality of bristles are mounted on the cleaning roller, and the bristles are soft bristles.

[0007] Preferably, a second gearbox is installed on the front side of the U-shaped frame, the front end output shaft of the cleaning roller extends to the outside and is fixedly connected to the rear end output shaft of the second gearbox, and pulleys are installed on the front end input shaft of the second gearbox and the output shaft of the drive motor, and the two pulleys are connected by a transmission belt.

[0008] Preferably, the dust removal mechanism includes a mounting plate fixedly connected to the rear side of the U-shaped frame, the lower end of the mounting plate is fixedly connected to a piston cylinder, the rear end rotating shaft of the cleaning roller extends to the outside and is fixedly connected to a rotating disk, the eccentric part of the rotating disk is rotatably connected to a connecting rod, a piston plate that can slide up and down is provided in the piston cylinder, and the other end of the connecting rod is rotatably connected to the lower end of the piston plate.

[0009] Preferably, a dust suction pipe is horizontally provided on the U-shaped frame, a plurality of dust suction holes are opened at the inner bottom of the dust suction pipe, the inner top space of the piston cylinder is connected with the outside through the air inlet, and the inner top space of the piston cylinder is connected with the rear end of the dust suction pipe through the air outlet pipe.

[0011] Preferably, a collection box is fixedly connected to the front side of the vertical plate located on the front side, a cylindrical groove is opened at the upper end of the collection box, the inner bottom of the cylindrical groove is connected with the outside through a sealing cover, a filter is fixedly connected to the inner wall of the cylindrical groove, the other end of the dust suction pipe is connected with a connecting pipe, the other end of the connecting pipe passes through the filter and is connected to a connecting cylinder through a rotating joint, a plurality of bent pipes are connected on the side wall of the connecting cylinder, and a spoiler is fixedly connected to the lower end of the connecting cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. A drive motor, a transmission gear, an incomplete gear and other structures are provided. By adopting this method, the plate can move intermittently, enter the U-shaped frame 5, move for a period of time, stop, and then continue to move. This can ensure that the plate is in a stationary state during the detection process, thus avoiding the situation where the movement affects the detection effect.

The rotation of the cleaning roller will also drive the rotating disk to rotate, causing the piston plate to reciprocate up and down, and continuously press out gas through the air outlet pipe. The pressed gas will enter the dust suction pipe. When the high-speed flowing gas passes through the dust suction pipe, the high-speed airflow will generate negative pressure, so the dust to be swept and oxygen can be sucked into the dust suction pipe, and enter the connecting pipe with the airflow, and finally enter the connecting cylinder and be discharged from multiple bends. This method can effectively avoid the secondary adhesion of dust.

[0015] 4. A filter screen and a water body are provided, and the dust enters the water body evenly along with the gas. The dust can fully contact the water body and thus enter the water body evenly. The filter screen can intercept the dust to prevent some dust from floating up with the bubbles and eventually being discharged from the surface of the water body.

[0016] 5. The connecting tube will also drive the spoiler to rotate and generate a vortex. As the water rotates, the dust gathers at the bottom of the water. This method can reduce the possibility of clogging the filter and enhance the continuity of the device.

[0017] In summary, the device uses a motor to drive the plate to move intermittently to facilitate detection. At the same time, the integrated cleaning system uses a rotating cleaning roller to sweep away dust and absorbs dust through the negative pressure of the air flow. The water body and the filter are combined to purify the dust, and the spoiler promotes water vortex to reduce filter clogging, ensuring the detection accuracy and the continuity of the device operation.

As an embodiment of the present invention, a collection box 9 is fixedly connected to the front side of the vertical plate 2 located on the front side, a columnar groove 10 is opened at the upper end of the collection box 9, the inner bottom of the columnar groove 10 is connected to the outside through a sealing cover 30, a filter screen 31 is fixedly connected to the inner wall of the columnar groove 10, the other end of the dust suction pipe 22 is connected to a connecting pipe 25, the other end of the connecting pipe 25 passes through the filter screen 31, and is connected to a connecting cylinder 32 through a rotating joint, and the inner top of the connecting cylinder 32 is connected to a vertical pipe, the upper end of the vertical pipe is connected to the connecting pipe 25 through a rotating joint, and a plurality of elbows 33 are connected to the side wall of the connecting cylinder 32, and the plurality of elbows 33 are as shown in FIG. Figure 6 As shown, after the multiple curved pipes 33 eject gas, they are subjected to a reaction force and rotate, and a spoiler 34 is fixedly connected to the lower end of the connecting tube 32 .

[0023] In the present invention, when in use, when the plate is placed on the conveyor belt 4, and then the drive motor 8 is started, after the drive motor 8 is started, the transmission gear 12 will be intermittently rotated through the incomplete gear 15, and the intermittent rotation of the transmission gear 12 will make one of the transmission rollers 3 intermittently rotate through the first gearbox 11, and the intermittent rotation of one of the transmission rollers 3 will make the conveyor belt 4 intermittently rotate, so that the plate intermittently moves, and after the plate intermittently moves, it will stop after moving for a period of time and then continue to move, which can ensure that the plate is in a stationary state during the detection process, so as to avoid the situation where the movement affects the detection effect; In addition, the start of the driving motor 8 will also drive the pulley 14 and cooperate with the second gearbox 13 to rotate the cleaning roller 23 and the plurality of bristles 24 to sweep and lift the dust on the surface of the plate, thereby achieving dust cleaning on the surface of the plate, thereby ensuring the accuracy of subsequent detection; In addition, the rotation of the cleaning roller 23 will also drive the rotating disk 19 to rotate, and the rotation of the rotating disk 19 will cause the piston plate 35 to reciprocate up and down through the connecting rod 26. The piston plate 35 moves up and draws gas through the air inlet 20, and the piston plate 35 moves down and presses the gas out through the air outlet pipe 21. The pressed gas will enter the dust suction pipe 22. When the high-speed flowing gas passes through the dust suction pipe 22, the high-speed airflow will generate negative pressure, so the dust to be swept and oxygenated can be sucked into the dust suction pipe 22 and enter with the airflow. The gas enters the connecting pipe 25, finally enters the connecting tube 32, and is discharged from the multiple bends 33. When the high-speed airflow is discharged from the multiple bends 33, the bends 33 drive the connecting tube 32 to rotate due to the reaction force of the gas. In this way, the gas ejected by the multiple bends 33 in a rotating state allows the dust entering the columnar groove 10 to fully contact the water body, thereby evenly entering the water body. The filter 31 can be used to intercept the dust, so as to prevent some dust from floating up with the bubbles and finally being discharged from the surface of the water body. In addition, the connecting tube 32 will also drive the spoiler 34 to rotate and generate a vortex, which is a vortex structure formed by the rotation of water flow. In this vortex, when the water flow rotates, it will form a centripetal force, which will push the sediment in the water body to the center of the vortex. Since the center of the vortex is at the bottom, the sediment will be pushed to this area and gathered there. Therefore, as the water body rotates, the dust gathers at the bottom part of the water body. By adopting this method, the possibility of clogging of the filter screen 31 can be reduced, and the continuity of the use of the device can be enhanced.
