Description

Technical Field

[0001] This utility model relates to the field of scanner technology, specifically to an unmanned defect scanner for screening wood. Background Technology

[0002] Timber originates from plants capable of secondary growth. The lignified tissue formed from these plants, after processing, can become boards, timber, or other various products. Wood veneers, with their unique and excellent properties, bring a distinctive and beautiful aesthetic. In construction projects, we must use timber economically and rationally, adhering to the principle of "using long timber rather than short timber, and using superior timber rather than inferior timber." Timber is scanned and screened, then strengthened, preserved, and fireproofed. To reduce deformation and cracking during use, timber is usually subjected to natural or artificial drying. These treatments not only improve the durability of the timber but also effectively extend its service life.

[0003] However, in the use of existing technologies, due to the long storage time of wood in warehouses, its surface may be contaminated with impurities and dust, which may affect the accuracy of material detection and the subsequent use of materials. Therefore, an unmanned defect scanner for screening wood has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide an unmanned defect scanner for screening timber, in order to solve the problem mentioned in the background art that timber may be contaminated with impurities and dust on its surface due to long storage time in warehouses, which may affect the accuracy of material detection and the subsequent use of materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an unmanned defect scanner for screening wood, comprising a device body, a cleaning roller rotatably connected inside the device body, a gear fixedly connected to one end of each of the two cleaning rollers, a support base fixedly connected to the front of the device body, a second motor fixedly connected to the upper surface of the support base, the output end of the second motor fixedly connected to one side of a gear via a coupling, a filter box fixedly connected to the lower surface of the device body, a fan fixedly connected to the lower surface of the device body, the output end of the fan fixedly connected to one side of the filter box, a dust collection box fixedly connected inside the device body, an air pipe fixedly connected to the front of the dust collection box, and the end of the air pipe away from the dust collection box fixedly connected to the input end of the fan.

[0006] Preferably, a third motor is fixedly connected to the back of the device body, and the output end of the third motor is fixedly connected to a lead screw via a coupling. The two ends of the lead screw are rotatably connected to the interior of the device body.

[0007] Preferably, the device body has two slide rods fixedly connected inside, and a limiting seat is slidably connected to the outer surface of the slide rods, with the limiting seat sleeved on the outer surface of the lead screw.

[0008] Preferably, four lamp bodies are fixedly connected to the lower surface of the limiting seat, and a camera is fixedly connected to the lower surface of the limiting seat.

[0009] Preferably, the device body has multiple transmission columns rotatably connected inside, and a first motor is fixedly connected to the front of the device body. The output end of the first motor is fixedly connected to one end of a transmission column through a coupling.

[0010] Preferably, the device body has two bidirectional threaded rods internally rotatably connected, and the outer surfaces of the two bidirectional threaded rods are each threaded with two limiting blocks, and the upper surfaces of the limiting blocks are rotatably connected with limiting wheels.

[0011] Preferably, the lower surface of the limiting block is fixedly connected with a protrusion, and the inner bottom wall of the device body has two sliding grooves, with the outer surfaces of every two protrusions slidably connected to the inside of one sliding groove.

A rotating disk is fixedly connected to the end of the bidirectional threaded rod near the second pulley.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This unmanned defect scanner for screening wood operates by starting the third motor, which drives the gears to rotate. The two gears mesh and drive the two cleaning rollers to rotate. The two cleaning rollers rub against the wood surface to remove impurities. Then, the fan is turned on to create negative pressure inside the dust collection box, which sucks up the impurities that have been removed by the cleaning rollers. The impurities are then passed through an air pipe into the filter box for filtration and storage, preventing impurities adhering to the wood surface from affecting subsequent wood inspection.

[0015] 2. This unmanned defect scanner for screening timber operates by rotating a rotating disk, which in turn drives a second pulley to rotate. Simultaneously, the second pulley drives a first pulley to rotate via a belt. This, in turn, causes the first and second pulleys to rotate two bidirectional threaded rods. At this time, two limiting blocks move towards the center position under the limiting action of the surface of the bidirectional threaded rods and the sliding groove. This clamps and limits the timber, preventing it from shifting during transport and thus avoiding any impact on the transport process or potential damage to the device. Attached Figure Description

An air pipe 9 is fixedly connected to the front of the dust collection box 8, which connects the dust collection box 8 and the fan 19. The end of the air pipe 9 away from the dust collection box 8 is fixedly connected to the input end of the fan 19. The dust collection box 8 consists of two parts located on both sides of the wood. It is hollow and has slots at opposite positions to suck up impurities from the wood surface.

[0023] The device body 1 has a third motor 14 fixedly connected to the back side. The output end of the third motor 14 is fixedly connected to a lead screw 15 via a coupling. The two ends of the lead screw 15 are rotatably connected to the inside of the device body 1. The third motor 14 drives the lead screw 15 to rotate.

[0024] The device body 1 has two slide rods 16 fixedly connected inside. The outer surface of the slide rods 16 is slidably connected to a limiting seat 17. The limiting seat 17 is sleeved on the outer surface of the lead screw 15. The limiting seat 17 is used to limit and fix the position of the lamp body 18.

[0025] The lower surface of the limiting seat 17 is fixedly connected to four lamp bodies 18, and the lower surface of the limiting seat 17 is fixedly connected to a camera 25. The lamp bodies 18 are used to illuminate the wood, making the wood detection clearer and more accurate.

[0026] The device body 1 has multiple transmission columns 3 rotatably connected inside. The front of the device body 1 is fixedly connected to a first motor 2. The output end of the first motor 2 is fixedly connected to one end of a transmission column 3 through a coupling. The first motor 2 drives the transmission column 3 to rotate.

[0027] The device body 1 has two bidirectional threaded rods 21 internally connected to each other. The outer surfaces of the two bidirectional threaded rods 21 are threaded with two limiting blocks 12. The upper surfaces of the limiting blocks 12 are rotatably connected with limiting wheels 13. The bidirectional threaded rods 21 are used to drive the limiting seat 17 to move.

[0028] Among them, the lower surface of the limiting block 12 is fixedly connected with a protrusion 11, and the inner bottom wall of the device body 1 is provided with two sliding grooves 10. The outer surface of each pair of protrusions 11 is slidably connected to the inside of one sliding groove 10. The sliding groove 10 serves to limit the position of the protrusion 11.

[0029] One end of a bidirectional threaded rod 21 is fixedly connected to a first pulley 22, and the outer surface of one end of another bidirectional threaded rod 21 is fixedly connected to a second pulley 24.

The rotating disk 23 drives the second pulley 24 and the bidirectional threaded rod 21 to rotate.

[0030] The motor is existing technology and will not be discussed in detail here. The components that match the motor include connecting wires, power supply, and microcontroller, which are also existing structures and will not be discussed in detail here.

[0031] Working Principle: In operation, the wood is placed on the surface of the transmission column 3 at the left end of the device. The first motor 2 is then started, driving the transmission column 3 to rotate and move the wood to the right. The rotating disc 23 then rotates, driving the second pulley 24 to rotate. Simultaneously, the second pulley 24 drives the first pulley 22 via a belt, causing the first and second pulleys 22 and 24 to rotate the two bidirectional threaded rods 21. At this time, the two limiting blocks 12 move towards the center position under the limiting action of the surface of the bidirectional threaded rods 21 and the sliding groove 10, clamping and limiting the wood with the two limiting wheels 13. This prevents the wood from shifting during transport, affecting the transport process and preventing potential damage to the device. Then, the third motor 14 is started, driving the gear 6 to rotate. The two gears 6 mesh and drive the two cleaning rollers 7 to rotate. The two cleaning rollers 7 rub and clean the wood surface to remove impurities. Then, the blower 19 is turned on to create a negative pressure inside the dust collection box 8, which sucks up the impurities that have been removed by the cleaning rollers 7 and passes them into the filter box 20 through the air pipe 9 for filtration and storage. When the cleaned wood moves to the bottom of the limiting seat 17, the third motor 14 is started to drive the lead screw 15 to rotate, so that the lead screw 15 and the limiting seat 17 can be driven to reciprocate. The limiting seat 17 slides back and forth on the surface of the slide rod 16. Under the illumination of the lamp body 18, the camera 25 takes pictures of the wood for identification, and the controller analyzes the pictures to rate the quality of the wood, thus completing the wood quality inspection.
