[0002] In the furniture manufacturing industry, especially for the production and processing of wooden furniture, improving production efficiency and processing accuracy is a continuous goal. In the traditional furniture manufacturing process, since both sides of the board need to be processed, it is necessary to turn the board over and process the other side after one side of the board is processed. When turning over, a robotic arm grabs and lifts the board from the upper surface of the board and makes the bottom surface of the board face another robotic arm. The other robotic arm grabs the board and puts it back on the workbench. At this time, the bottom surface of the board is turned to the top surface of the board, thereby completing the board's reversal and flipping work. In this process, two robotic arm equipment are required to cooperate to complete the board reversal work. The operation method is cumbersome and the equipment cost investment is high.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0017] like Figures 1 to 6 As shown, an automatic reversing mechanism for processing wooden furniture of the present invention comprises a moving platform 26 that moves vertically, a back plate 2 that is rotatably mounted on the moving platform 26, and two sets of fixing units 3 that are arranged on the back plate 2, and the two sets of fixing units 3 are used to fix the front and rear sides of the plate 1; The fixing unit 3 includes a turntable 4 rotatably mounted on the back plate 2, a support plate 5 is fixed on the turntable 4, a telescopic structure 6 capable of extension and retraction is provided on the support plate 5, two groups of clamping structures 7 are provided on the telescopic structure 6, and the two groups of clamping structures 7 are controlled to move closer to or away from each other through the telescopic movement of the telescopic structure 6, and the clamping structure 7 is used to clamp and fix the plate 1; When the clamping structure 7 clamps the plate 1 , the movable platform 26 rises and carries the plate 1 upward, and when the turntable 4 rotates, the support plate 5 and the telescopic structure 6 flip from the upper surface of the plate 1 to the lower surface of the plate 1 .

[0018] In detail, the upward movement of the movable platform 26 can lift the plate 1 off the workbench or conveyor belt, and the downward movement of the movable platform 26 can place the flipped plate 1 back on the workbench or conveyor belt. The movement of the movable platform 26 can be powered by commonly used structures such as oil cylinders and air cylinders provided externally. The back plate 2 is rotatably mounted on the movable platform 26. The movable platform 26 provides support for the back plate 2, and the rotation of the back plate 2 can flip the plate 1. The two sets of fixing units 3 can fix the front and back sides of the plate 1, thereby improving the stability of the plate 1 during movement. When the plate 1 is initially grabbed, the support plate 5 and the telescopic structure 6 are both located above the plate 1. When the back plate 2 rotates, if the positions of the support plate 5 and the telescopic structure 6 relative to the back plate 2 are not The support plate 5 and the telescopic structure 6 are located above the plate 1 again when the back plate 2 is rotated, so as to facilitate the placement of the plate 1 after the reversal. The two turntables 4 rotate in opposite directions, and the turntable 4 drives the support plate 5 and the telescopic structure 6 to bypass the edge of the plate 1 and rotate to the bottom of the plate 1.

[0019] When in use, the movable platform 26 is located at the initial height, and the telescopic structure 6 is contracted and the two groups of clamping structures 7 are brought closer to each other. The two groups of clamping structures 7 clamp and fix the left and right sides of the plate 1 respectively, and the two groups of fixing units 3 simultaneously clamp and fix the front and back sides of the plate 1. The movable platform 26 moves upward and moves the plate 1 upward. After the plate 1 leaves the workbench or the conveyor belt, the turntable 4 is rotated, and the turntable 4 rotates the support plate 5 and the telescopic structure 6 from the top of the plate 1 to the bottom of the plate 1, and then the back plate 2 is rotated, so that the back plate 2 drives the two groups of fixing units 3 to flip, and the two groups of fixing units 3 drive the plate 1 to flip, thereby realizing the reversing work of the plate 1. At this time, the support plate 5 and the telescopic structure 6 are moved back to the top of the plate 1, and the movable platform 26 moves down to the initial position, and the plate 1 is placed back on the workbench or the conveyor belt. At this time, the flipping circular work of the plate 1 is completed.

[0020] By adopting a single automatic reversing mechanism to replace the original mode that requires two robotic arms to work together, the equipment cost investment is significantly reduced, while the operation process is simplified and the production efficiency is improved; the various components in the mechanism, such as the lifting and lowering of the movable platform 26, the rotation of the back plate 2, and the movement design of the support plate 5 and the telescopic structure 6 driven by the turntable 4, realize the fully automated process from plate grabbing, flipping to repositioning, reducing human intervention, not only improving the operation efficiency, but also reducing the risk of manual operation errors; compared with the traditional method that requires a larger space to coordinate the operation of two robotic arms, the automatic reversing mechanism is more compact, optimizes the production space layout, and is conducive to the integration and miniaturization of the production line; in summary, the design of the automatic reversing mechanism for wooden furniture processing shows obvious advantages in improving production efficiency, reducing equipment costs, ensuring processing accuracy, enhancing the level of automation, optimizing space utilization, and improving operation safety.

[0021] Further, the telescopic structure 6 includes a double-threaded sleeve 8 rotatably mounted on the support plate 5, threads are arranged on the inner and outer walls of the double-threaded sleeve 8, and the threads on the inner and outer sides of the double-threaded sleeve 8 have opposite rotation directions, an internally threaded sleeve 9 is threadedly sleeved on the outer side of the double-threaded sleeve 8, and an externally threaded rod 10 is threadedly sleeved on the inner side of the double-threaded sleeve 8, and connecting arms 11 are arranged on the internally threaded sleeve 9 and the externally threaded rod 10, and the two connecting arms 11 are respectively connected to the two groups of clamping structures 7, and when the double-threaded sleeve 8 rotates, the double-threaded sleeve 8 pushes the internally threaded sleeve 9 and the externally threaded rod 10 to move synchronously in the opposite direction; A first motor 12 and a first transmission wheel 13 for providing power for the rotation of the double-threaded sleeve 8 are arranged on the support plate 5 .

[0022] In detail, the two connecting arms 11 are both located on one side of the double-threaded sleeve 8, the support plate 5, the first motor 12 and the first transmission wheel 13 are located on the other side of the double-threaded sleeve 8, the lengths of the internally threaded sleeve 9, the double-threaded sleeve 8 and the externally threaded rod 10 increase in sequence, the tail end of the double-threaded sleeve 8 extends to the outside of the internally threaded sleeve 9, the tail end of the externally threaded rod 10 extends to the outside of the double-threaded sleeve 8, the first motor 12 is fixed on the support plate 5, the first transmission wheel 13 is installed on the output end of the first motor 12, and the first transmission wheel 13 is connected to the double-threaded sleeve 8. The sleeve 8 is connected in transmission, and the internal threaded sleeve 9 and the external threaded rod 10 can both move laterally along the length direction of the double-threaded sleeve 8. When the double-threaded sleeve 8 rotates, due to the effect of the threads on the double-threaded sleeve 8, the double-threaded sleeve 8 can push the internal threaded sleeve 9 and the external threaded rod 10 to approach or move away from each other synchronously. At this time, the internal threaded sleeve 9 and the external threaded rod 10 drive the two groups of clamping structures 7 to approach or move away from each other through the two connecting arms 11. When the two groups of clamping structures 7 are close to each other, the two groups of clamping structures 7 clamp and fix the plate 1.

[0023] The above structural method can also locate the center points of the two groups of clamping structures 7 .

[0024] Furthermore, a guide plate 14 is slidably inserted into the support plate 5 , one end of the guide plate 14 is fixedly connected to the external threaded rod 10 , and the other end of the guide plate 14 is slidably connected to the internal threaded sleeve 9 .

[0025] In detail, the guide plate 14 can guide the internal threaded sleeve 9 and the external threaded rod 10, that is, when the internal threaded sleeve 9 moves, it slides on the guide plate 14, and when the external threaded rod 10 moves, it drives the guide plate 14 to slide on the support plate 5.

[0026] Furthermore, the clamping structure 7 includes a top block 15 and two clamping plates 16. The upper and lower surfaces of the top block 15 are both inclined surfaces. The two clamping plates 16 are slidably mounted on the two inclined surfaces of the top block 15. When the top block 15 abuts against the side wall of the plate 1, the two clamping plates 16 approach each other and squeeze and fix the upper and lower surfaces of the plate 1. A support shaft 17 is fixed on the top block 15, a sliding sleeve 18 is slidably mounted on the support shaft 17, the sliding sleeve 18 is connected to the support shaft 17 via a spring 19, the sliding sleeve 18 is connected to the two clamping plates 16 via two inclined push-pull arms 20, a rotating sleeve 21 is rotatably mounted on the sliding sleeve 18, and the connecting arm 11 is connected to the rotating sleeve 21.

[0027] In detail, the spring 19 provides thrust for the support shaft 17 and tension for the sliding sleeve 18. When the spring 19 is in the natural state, the two clamping plates 16 on the top block 15 are separated from each other. When the telescopic structure 6 pushes the two groups of clamping structures 7 to approach each other, the connecting arm 11 drives the support shaft 17, the top block 15 and the two clamping plates 16 to move toward the plate 1 through the sliding sleeve 18. The end of the top block 15 abuts against the side wall of the plate 1. At this time, the top block 15 stops moving, and the sliding sleeve 18 continues to move and drives the spring 19 to undergo elastic deformation. The sliding sleeve 18 pushes the two clamping plates 16 to slide on the upper and lower inclined surfaces of the top block 15 through the two push-pull arms 20. The two clamping plates 16 approach each other in the vertical direction and squeeze and fix the upper and lower surfaces of the plate 1. Thus, the two top blocks 15 on the two groups of clamping structures 7 fix the plate 1 in the horizontal direction, and the two clamping plates 16 on the top block 15 fix the plate 1 in the vertical direction.

[0028] Since the turntable 4 needs to exchange the positions of the support plate 5 and the telescopic structure 6, when the turntable 4 rotates, since the clamping structure 7 maintains the clamping state of the plate 1, the connecting arm 11 will drive the rotating sleeve 21 to rotate on the sliding sleeve 18, which will not affect the clamping work of the clamping structure 7.

[0029] Furthermore, two arc-shaped slots are formed on the rotating sleeve 21 , and two clamping blocks 22 are slidably provided on the sliding sleeve 18 for use in conjunction with the two slots. The clamping blocks 22 are connected to the sliding sleeve 18 via spring pieces 23 .

[0030] In detail, in the natural state, the spring piece 23 pushes the block 22 to be stuck in the slot. At this time, the rotating sleeve 21 and the sliding sleeve 18 are relatively stationary. When the turntable 4 rotates, the rotating sleeve 21 overcomes the blocking force of the block 22 and rotates on the sliding sleeve 18. The block 22 slides on the sliding sleeve 18, and the spring piece 23 is elastically deformed. When the rotating sleeve 21 completes the rotation, the block 22 is re-slotted into the slot. Since the sliding sleeve 18 rotates a semicircle, the positions of the two slots can be swapped and used.

[0031] Furthermore, two second transmission wheels 24 and a second motor 25 are provided on the back plate 2. The second transmission wheels 24 rotate on the back plate 2. The two second transmission wheels 24 are respectively connected to the two turntables 4. The two second transmission wheels 24 are connected to each other. The second motor 25 is driven by one second transmission wheel 24.

[0032] In detail, the second motor 25 is fixed on the back plate 2, the two second transmission wheels 24 are of equal diameters, and the two turntables 4 are of equal diameters. When the second motor 25 drives the two second transmission wheels 24 to rotate, the two turntables 4 rotate synchronously, and the rotation directions of the two turntables 4 are opposite, thereby providing power for the two groups of fixed units 3.

[0033] Furthermore, a triangular ring groove 27 is provided on the side wall of the moving platform 26, and two sliding posts 28 are slidably arranged in the triangular ring groove 27, and the two sliding posts 28 are connected to the back plate 2; The bottom of the triangular ring groove 27 is horizontal. When the sliding post 28 slides in the triangular ring groove 27, one sliding post 28 moves horizontally at the bottom of the triangular ring groove 27, and the other sliding post 28 slides into the hypotenuse of the triangular ring groove 27. When one sliding post 28 slides from one side of the bottom of the triangular ring groove 27 to the other side, the other sliding post 28 passes through the two hypotenuses of the triangular ring groove 27 and slides back into the bottom of the triangular ring groove 27.

[0034] In detail, the two oblique sides of the triangular ring groove 27 are both arc-shaped, and the sliding column 28 can slide in the triangular ring groove 27. Since the bottom of the triangular ring groove 27 is horizontal, when one sliding column 28 slides at the bottom of the triangular ring groove 27, the other sliding column 28 will slide in the two oblique sides of the triangular ring groove 27. At this time, the two sliding columns 28 drive the back plate 2 and the plate 1 to flip, and the back plate 2 and the plate 1 flip upward, thereby avoiding the collision between the plate 1 and the workbench or the conveyor belt when the plate 1 is installed. There is at least one sliding column 28 at the bottom of the triangular ring groove 27, so that when one sliding column 28 slides from one side of the bottom of the triangular ring groove 27 to the other side, the other sliding column 28 passes through the two oblique sides of the triangular ring groove 27 and slides back into the bottom of the triangular ring groove 27. At this time, the flipping and reversing work of the plate 1 is completed.

[0035] Furthermore, the back plate 2 is in the shape of a capsule, and two slide columns 28 are respectively installed at the center positions of the arc-shaped parts on the left and right sides of the back plate 2. A worm gear is provided on the outer wall of the back plate 2, and a third motor 29 is provided on the movable platform 26. A worm 30 is provided at the output end of the third motor 29. The worm 30 is horizontal, and the worm 30 is meshed with the worm gear at the bottom of the back plate 2.

[0036] In detail, by limiting the shape of the back plate 2, when the back plate 2 is flipped, the height position of the lowest point of the back plate 2 remains unchanged. Since the worm 30 is horizontal, when the back plate 2 is flipped, the worm teeth at the bottom of the back plate 2 can always maintain a meshing state with the worm 30. The third motor 29 drives the back plate 2 to flip through the worm 30, thereby providing power for the flipping movement of the plate 1.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
