[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an unmanned defect scanner for wood processing, comprising a main body 1, two vertical plates 2 fixedly connected to the upper surface of the main body 1, a lifting plate 3 disposed between the two vertical plates 2, a mounting plate 4 disposed on the lower side of the lifting plate 3, a scanner body 5 fixedly mounted on the lower surface of the mounting plate 4, two protective covers 6 disposed on the lower side of the lifting plate 3, round rods 7 fixedly connected to both sides of the two protective covers 6, two vertical grooves 9 and two inclined grooves 8 respectively opened on the adjacent side surfaces of the two vertical plates 2, adjacent vertical grooves 9 and inclined grooves 8 are connected, the round rods 7 are slidably connected to the vertical grooves 9 and inclined grooves 8, through grooves 10 are opened inside the two vertical plates 2, a lifting mechanism is disposed inside the left through groove 10, a guide groove 16 is opened on the lower surface of the lifting plate 3, an adjustment component is disposed inside the guide groove 16, and two clamping components 21 are disposed inside the main body 1.

[0024] In the above embodiments, both the scanner body 5 and the clamping component 21 are existing technologies, and are based on the same principle as those in the publication number CN219302465U. Since they are mature technologies known in the field, they will not be described in detail here. In addition, a rubber pad can be provided on the side of the clamping component 21 that contacts the wood, so as to avoid damage to the wood caused by the clamping component 21, and at the same time improve the stability of clamping the wood.

[0025] The lower surface of the lifting plate 3 has two limiting grooves 11, which are located on both sides of the guide groove 16. Each limiting groove 11 is fixedly connected to a limiting rod 12. Two protective covers 6 are slidably connected inside the two limiting grooves 11 and slidably sleeved on the outside of the two limiting rods 12. The setting of the limiting grooves 11 and the limiting rods 12 makes it easy to limit the movement trajectory of the protective covers 6, thereby ensuring the stability of the protective covers 6 when it moves.

[0026] The lifting mechanism includes a first threaded rod 13, which is rotatably connected to the inside of the left through slot 10. Fixing blocks 14 are fixedly connected to both sides of the lifting plate 3. The lifting plate 3 is slidably connected to the inside of the two through slots 10 via the fixing blocks 14. The left fixing block 14 is threadedly connected to the outside of the first threaded rod 13. Rotation of the first threaded rod 13 drives the lifting plate 3 to move between the two vertical plates 2, thereby moving the scanner body 5. Simultaneously, the lifting plate 3 also moves the protective cover 6. Since the round rod 7 is slidably connected to the inside of the vertical slot 9 and the inclined slot 8, when the protective cover 6 descends, the round rod 7 and the inclined slot 8 work together to move the two protective covers 6 to opposite sides. When the scanner body 5 moves to the detection area, the round rod 7 enters the inside of the vertical slot 9, and the two protective covers 6 no longer obstruct or protect the scanner body 5. When the height of the scanner body 5 is subsequently adjusted, the round rod 7 will only slide inside the vertical slot 9, thus not moving the protective cover 6.

[0027] A first motor 15 is fixedly connected to the upper surface of the left vertical plate 2. The output shaft of the first motor 15 rotates through the interior of the left vertical plate 2. The output shaft of the first motor 15 is fixedly connected to the first threaded rod 13 through a coupling. The first threaded rod 13 can be rotated by starting the first motor 15.

[0028] The guide groove 16 is rotatably connected to a second threaded rod 17. The mounting plate 4 is slidably connected to the inside of the guide groove 16 and threadedly connected to the outside of the second threaded rod 17. The surface of the right-side fixing block 14 is fixedly connected to a second motor 18. The right end of the second threaded rod 17 is fixedly connected to an extension rod 19. The extension rod 19 rotates through the inside of the lifting plate 3. The output shaft of the second motor 18 rotates through the inside of the lifting fixing block 14. The output shaft of the second motor 18 is fixedly connected to the extension rod 19 via a coupling. By starting the second motor 18, the extension rod 19 can be rotated. The rotation of the extension rod 19 can be rotated, which in turn can be rotated, which in turn can be rotated, which in turn can be rotated, which in turn can be rotated, which can be used to move the mounting plate 4, thereby achieving the lateral adjustment of the scanner body 5.

[0029] The main body 1 has a cavity 22 inside, and two mounting shafts 23 are rotatably connected inside the cavity 22. The two mounting shafts 23 have their adjacent ends rotatably extending through the temporal part of the main body 1. The two mounting shafts 23 are respectively fixedly connected to two clamping components 21.

[0030] The cavity 22 is equipped with two drive rods 24. Each drive rod 24 is rotatably fitted with a support frame 20. The support frame 20 is fixedly connected to the inner wall of the cavity 22. The drive rods 24 and the end of the mounting shaft 23 that are close to each other are fixedly fitted with bevel gears 25. The two adjacent bevel gears 25 are meshed and connected. The support frame 20 ensures the stability of the drive rods 24 and also ensures the stability of the meshing of the two bevel gears 25.

[0031] Both drive rods 24 are fixedly fitted with synchronous pulleys 26, and synchronous belts 27 are meshed with the outside of the two synchronous pulleys 26. A third motor 28 is fixedly connected to the front surface of the main body 1. The output shaft of the third motor 28 rotates through the interior of the main body 1. The output shaft of the third motor 28 is fixedly connected to the left drive rod 24 by means of a coupling. By starting the third motor 28, the left drive rod 24 can be driven to rotate. At this time, under the transmission of the two synchronous pulleys 26 and the synchronous belt 27, both drive rods 24 will rotate. Through the rotation of the drive rods 24 and the transmission of the bevel gear 25, the mounting shaft 23 can be driven to rotate. At this time, the two mounting shafts 23 rotate in the same direction, thereby realizing the rotation of the clamping assembly 21, thus realizing the flipping of the wood.

[0032] Among them, the first motor 15, the second motor 18 and the third motor 28 are also equipped with power supply, wires, controller and microcomputer and other structures. Since they are not the main structures, they will not be described in detail in this article. At the same time, the wiring of the second motor 18 has a certain margin, so that when the second motor 18 moves, the wiring will not be dragged.

[0033] Working principle:

[0034] When using this unmanned defect scanner for wood processing, the operator places the wood to be inspected inside the frame of the main body 1 and fixes it with the clamping assembly 21. Then, the first motor 15 is started, which drives the rotation of the first threaded rod 13. The rotation of the first threaded rod 13 drives the lifting plate 3 to move between the two vertical plates 2, thereby moving the scanner body 5. At the same time, the lifting plate 3 also moves the protective cover 6. Since the round rod 7 is slidably connected inside the vertical groove 9 and the inclined groove 8, when the protective cover 6 is lowered, it will move the two protective covers 6 to the side away from each other with the cooperation of the round rod 7 and the inclined groove 8. After the scanner body 5 moves to the inspection area, the round rod 7 will enter the interior of the vertical groove 9, and the two protective covers 6 will no longer block or protect the scanner body 5, so as to facilitate subsequent defect scanning of the wood. When the height of the scanner body 5 is adjusted later, since the round rod 7 only slides inside the vertical groove 9, it will not move the protective cover 6.

[0035] When the position of the scanner body 5 needs to be adjusted, the second motor 18 is started to drive the extension rod 19 to rotate. The rotation of the extension rod 19 drives the rotation of the second threaded rod 17. The rotation of the second threaded rod 17 drives the movement of the mounting plate 4, thereby realizing the horizontal adjustment of the position of the scanner body 5.

[0036] When the wood needs to be turned over, the scanner body 5 is first reset. Then, with the cooperation of the inclined groove 8, the two protective covers 6 will close again to protect the scanner body 5. Then, the third motor 28 is started. By starting the third motor 28, the left drive rod 24 can be rotated. At this time, under the transmission of the two synchronous pulleys 26 and the synchronous belt 27, both drive rods 24 will rotate. Through the rotation of the drive rod 24 and the transmission of the bevel gear 25, the mounting shaft 23 can be rotated. At this time, the two mounting shafts 23 rotate in the same direction, thereby realizing the rotation of the clamping assembly 21, thus realizing the turning over of the wood.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
