Description

Technical Field

[0001] This invention relates to the field of door leaf flipping technology, and more particularly to an adaptive flipping device. Background Technology

[0002] The door leaf is the main part of a door, a component that can be opened and closed from both sides. It plays an important role in architecture and furniture. A door leaf generally consists of a frame composed of top, middle, and bottom rails and side rails, with the door core panel fixed in the middle. Its components also include the door core, transition layer, edge banding, finish, and decorative moldings.

[0003] In the industrial processing of door panels, due to the requirements of finished product quality and performance, both sides of the door panel need to undergo multiple fine processing operations such as grinding, painting, film coating, or engraving. This inevitably requires the door panel to be rotated 180° during process transition. However, most of the door panel rotation devices currently used in the industry require rigid matching design with specific conveyor lines. Not only does the installation and debugging of the device need to be precisely matched with the operating rhythm and conveying height of the conveyor system, but the adaptation adjustment process is also cumbersome when facing the processing needs of door panels of different sizes and specifications. At the same time, such integrated equipment is difficult to apply alone to small-batch, multi-variety door panel processing scenarios, which brings significant inconvenience to production organization and flexible equipment allocation.

[0004] Therefore, an adaptive flipping device needs to be designed to solve the above problems. Summary of the Invention

[0008] As a preferred embodiment of the present invention, the flipping assembly includes two flipping bearing seats symmetrically and fixedly installed on the top surface of the support bracket. A flipping frame is rotatably mounted on the inner wall of the two flipping bearing seats via a shaft. A worm gear is fixedly installed at the end of one shaft.

A limit mechanism is provided on the other shaft. Clamping mechanisms are provided at the four corners of the flipping frame.

[0009] As a preferred embodiment of the present invention, the limiting mechanism includes a limiting frame fixedly fitted on the outer wall of the shaft, the limiting frame having a plurality of limiting holes arranged in a circular array on its side, a limiting cylinder fixedly installed on the top surface of the support bracket, and a limiting rod adapted to the limiting hole fixedly installed on the telescopic end of the limiting cylinder.

[0010] As a preferred embodiment of the present invention, the clamping mechanism includes a clamping cylinder fixedly installed on the inner wall of one corner of the flipping frame, and a clamping plate is fixedly installed on the telescopic end of the clamping cylinder.

[0011] As a preferred embodiment of the present invention, the lifting assembly includes four guide frames fixedly installed on the top surface of the support plate at a position inside the bracket. Guide columns are slidably installed on the inner wall of the guide frames. A lifting plate is fixedly installed on the top of the four guide columns. A lifting motor is fixedly installed on the top surface of the support plate through a mounting seat. A lifting gear is fixedly installed on the output end of the lifting motor. A connecting column is fixedly installed on the bottom surface of the lifting plate. A lifting rack that meshes with the lifting gear is fixedly installed on the side of the connecting column.

[0012] In a preferred embodiment of the present invention, the lifting plate is located directly below the tilting frame.

[0013] As a preferred embodiment of the present invention, the lifting structure includes clamping seats disposed on the fork plate and the lifting plate. One clamping seat is fixedly connected to the top surface of the fork plate and the other is slidably connected to the top surface of the lifting plate. An extension plate is fixedly installed on the side of the clamping seat. Two rotating shafts are symmetrically rotatably installed on the inner wall of the clamping seat. A transmission gear is fixedly installed at one end of the rotating shaft, and the two transmission gears mesh. A fixing clamping plate is fixedly fitted on the outer wall of the rotating shaft.

[0014] As a preferred embodiment of the present invention, the top surface of the lifting plate is symmetrically provided with two guide grooves, and the bottom surface of the clamping seat on the lifting plate is symmetrically and fixedly installed with two guide blocks that are slidably connected to the guide grooves.

[0015] As a preferred embodiment of the present invention, the two fixed clamps are provided with anti-slip textures on their opposite sides.

[0016] The present invention has the following beneficial effects: 1. In this invention, the entire process of door panel loading, positioning, flipping, double-sided processing to unloading is automated. Through the precise linkage of mechanisms such as forklift transfer, flipping frame flipping, and lifting component coordination, no manual intervention is required for clamping and flipping switching. Compared with traditional flipping equipment that requires manual assistance, it reduces manual operation steps and waiting time, adapts to the needs of industrial mass production, and improves overall processing efficiency. At the same time, by integrating a vision inspection probe, it realizes deep perception and collaboration between the conveying system and processing equipment. The online quality inspection function of the vision inspection probe upgrades the simple material conveying equipment into an intelligent workstation with quality traceability capabilities, thereby improving the automation and intelligence level of the production line. 2. In this invention, a multi-point positioning structure of four corner clamping cylinders and anti-slip clamping plates of the flipping frame is adopted, which is combined with the bottom clamping mechanism of the fork plate to achieve stable fixation of the door leaf throughout the entire process. During the flipping process, the worm gear self-locking transmission pair and the limit cylinder rod locking structure are used to ensure that the flipping frame is accurately positioned and has a stable posture at the processing and loading / unloading stations, avoiding the offset and shaking of the door leaf during flipping and processing, and providing a reliable guarantee for high-precision processing. 3. In this invention, the fork plate adopts gear and rack meshing transmission, and with the guide rail guidance, it achieves smooth and precise translation, adapting to the switching needs of different workstations. The coordinated design of the lifting component and the tilting component can flexibly complete the space clearance and posture adjustment during the door panel changing process. It does not need to be rigidly matched with a specific conveyor line. It can adapt to both batch standardized production and flexible allocation for small batch multi-specification door panel processing, reducing equipment usage restrictions.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: An adaptive flipping device disclosed in this example, referring to... Figure 1-8The system includes a support plate 11 and a support base plate 12 fixedly installed on one side of the top surface of the support plate 11. A bracket 13 is fixedly installed on the other side of the top surface of the support plate 11. A support bracket 14 is fixedly installed on the top surface of the bracket 13. A fork assembly for raising and lowering the door leaf is provided on the support base plate 12. A flipping assembly for flipping the door leaf is provided on the support bracket 14. A lifting assembly for raising and lowering the door leaf in cooperation with the flipping assembly is provided on the bracket 13. Both the fork assembly and the lifting assembly are provided with a lifting structure. A vision inspection probe 15 for monitoring the workpiece is fixedly installed on the side wall of the support bracket 14 through a mounting bracket. The vision inspection probe 15 is used to collect the position information, outline size and posture data of the door leaf to be processed in real time. The equipment dynamically adjusts the operating parameters of the fork assembly, lifting assembly and flipping assembly according to the data fed back by the vision inspection probe 15 to achieve precise material transfer and posture control. The fork assembly includes a fork plate 21 disposed on the top surface of the support base plate 12. Two guide rails 22 are symmetrically and fixedly installed on the top surface of the support base plate 12. Two sliding frames 23 that are slidably connected to the guide rails 22 are symmetrically and fixedly installed on the bottom surface of the fork plate 21. A drive structure for driving the fork plate 21 is provided on the inner side of the support base plate 12 through a fixing frame. The lifting structure includes a clamping seat 61 mounted on the fork plate 21. An extension plate 65 is fixedly mounted on the side of the clamping seat 61. Two rotating shafts 62 are symmetrically rotatably mounted on the inner wall of the clamping seat 61. A transmission gear 63 is fixedly mounted on one end of the rotating shaft 62, and the two transmission gears 63 mesh. A fixing clamping plate 64 is fixedly fitted on the outer wall of the rotating shaft 62. Anti-slip textures are provided on the opposite sides of the two fixing clamping plates 64. A push cylinder 66 is hinged to the end of the extension plate 65 away from the clamping seat 61. The extension end of the push cylinder 66 is hinged to the side of the fixing clamping plate 64.

[0021] The implementation principle of this embodiment is as follows: The working process of the fully automatic door leaf flipping processing device is as follows: In use, the door leaf to be processed is first transferred to the designated work position of the fork plate 21 by the transfer equipment, and the initial positioning is completed by the matching lifting structure, so that the door leaf is placed stably in a vertical posture perpendicular to the fork plate 21. Specifically, after the door leaf is accurately transported to the inner area of ​​the clamping seat 61 by the transfer equipment, the cylinder 66 is immediately started and drives one of the fixed clamping plates 64 to rotate through the rotating shaft 62. Since there are meshing transmission gears 63 between the two rotating shafts 62, under the meshing transmission action of the gears, the other rotating shaft 62 rotates synchronously in the opposite direction, thereby driving the two fixed clamping plates 64 to rotate. The clamping plates 64 move in a direction closer to each other along a preset trajectory, ultimately achieving a firm clamping of the bottom of the door leaf and completing the clamping and fixing of the door leaf. After the door leaf is fixed, the drive structure starts and drives the fork plate 21 to move horizontally. At this time, the tilting assembly is in the initial vertical state. When the fork plate 21 drives the door leaf to move into the clamping range of the tilting assembly, the clamping mechanism of the tilting assembly is activated and completes the secondary fixing of the door leaf. Then, the piston rod of the cylinder 66 is pushed to shorten, causing the two fixed clamping plates 64 to move in the opposite direction to release the door leaf. The fork plate 21 is then reset to the initial position under the drive of the drive structure. After the tilting assembly completes the fixing of the door leaf, its drive unit starts and drives the door leaf to tilt counterclockwise. After rotating 90° to a horizontal position, the first surface of the door leaf can be sanded and painted. Once the first surface is finished, the tilting assembly rotates 90° counter-clockwise to return the door leaf to a vertical position. Then, the lifting assembly activates, raising its supporting clamping structure until it precisely aligns with and secures the clamping part of the door leaf. Simultaneously, the tilting assembly's clamping mechanism releases, and the lifting assembly moves the door leaf downwards a short distance, creating sufficient operating space for the tilting assembly's subsequent actions. The tilting assembly's drive unit then rotates 180° counter-clockwise. After the tilting assembly returns to a clamping position, the lifting assembly moves the door leaf upwards, allowing it to... The door leaf re-enters the clamping range of the flipping assembly and is fixed therein. The flipping assembly then rotates the door leaf counterclockwise by 90°, so that the second processing surface of the door leaf is horizontal and facing upwards. At this point, the other side of the door leaf can be processed. After both sides of the door leaf are processed, the flipping assembly rotates the door leaf clockwise by 90° again, restoring it to a vertical position. Subsequently, the fork plate 21, driven by the drive structure, moves horizontally to the work station below the door leaf. The lifting structure then supports and fixes the processed door leaf. Simultaneously, the flipping assembly releases the door leaf, and the fork plate 21 transfers the door leaf to its own bearing area and extends horizontally to the unloading station, finally completing the fully automatic flipping processing and unloading operation of the door leaf. The flipping direction is as follows: Figure 2For reference, during the entire flipping and processing process, the vision inspection probe 15 on the side wall of the support bracket 14 remains active. Specifically, during the loading stage, the vision inspection probe 15 performs an initial identification of the door leaf entering the working range of the fork plate 21, obtaining its geometric dimensions and initial placement posture. The equipment control system uses this information to predict the extension distance of the fork plate 21 and the clamping force of the clamping seat 61. Before the door leaf is handed over to the flipping frame 32, the vision inspection probe 15 performs a second calibration of the door leaf position to ensure that the clamping cylinder 36 on the flipping frame 32 can accurately clamp the four corners of the door leaf. When the door leaf completes processing on one side and flips to the other side, the vision inspection probe 15 performs online quality inspection on the processed surface and feeds the inspection results back to the equipment control system in real time. If a defect is detected, the control system can record the ID of the door leaf and adjust the parameters of subsequent processes, or mark it as a defective product during unloading, realizing closed-loop quality control based on visual feedback. This not only replaces manual visual inspection but also enables the equipment to adaptively adjust according to the workpiece status.

[0022] Example 2: Based on Example 1, this example discloses an adaptive flipping device, such as... Figure 3 , Figure 4 and Figure 8 As shown, the drive structure includes a fork bearing seat 24 fixedly installed on the top surface of the fixed frame. A support shaft 25 is rotatably installed on the inner wall of the fork bearing seat 24. Fork gears 26 are fixedly installed at both ends of the support shaft 25. Two fork racks 27 that mesh with the fork gears 26 are fixedly installed on the bottom surface of the fork plate 21. A fork motor 28 is fixedly installed on the top surface of the fixed frame. A reducer 29 is fixedly installed at the output end of the fork motor 28. A drive bevel gear 210 is fixedly installed at the output end of the reducer 29. A driven bevel gear 211 that meshes with the drive bevel gear 210 is fixedly fitted on the outer wall of the support shaft 25.

[0023] The implementation principle of this embodiment is as follows: When performing translational driving operation on the fork plate 21, the fork motor 28 is first started. The power output by the motor is reduced in speed and increased in torque by the reducer 29, and then transmitted to the drive bevel gear 210 to drive it to rotate. Since the drive bevel gear 210 and the driven bevel gear 211 are in a perpendicular meshing assembly relationship, the power can be efficiently transmitted to the driven bevel gear 211 through gear meshing, thereby synchronously driving the support shaft 25, which is coaxially connected to the driven bevel gear 211, to rotate; the support shaft 25 The fork gears 26 are symmetrically mounted at both ends. The fork gears 26 and the fixed fork racks 27 form a precise meshing pair. When the support shaft 25 drives the fork gears 26 at both ends to rotate synchronously, the meshing force between the gears and racks will be converted into a horizontal driving force, which pushes the fork plate 21 to slide smoothly in a straight line along the guide rail 22 pre-laid on the top surface of the support base plate 12 by means of the sliding frame 23 mounted at its bottom. Finally, the precise translation drive of the fork plate 21 is achieved to meet the workstation switching requirements during the door transfer process.

[0024] Example 3: Based on Example 1, this example discloses an adaptive flipping device, such as... Figure 1 and Figure 5 As shown, the flipping assembly includes two flipping bearing seats 31 symmetrically fixedly installed on the top surface of the support bracket 14. A flipping frame 32 is rotatably installed on the inner wall of the two flipping bearing seats 31 via a shaft. A worm gear 33 is fixedly installed at the end of one shaft. A flipping motor 34 is fixedly installed on the top surface of the support bracket 14. A worm 35 that meshes with the worm gear 33 is fixedly installed at the output end of the flipping motor 34. A limit mechanism is provided on the other shaft. Clamping mechanisms are provided at the four corners of the flipping frame 32. The limiting mechanism includes a limiting frame 41 fixedly mounted on the outer wall of the shaft. The side of the limiting frame 41 has several limiting holes 42 arranged in a circular array. A limiting cylinder 43 is fixedly installed on the top surface of the support bracket 14. A limiting rod 44 adapted to the limiting hole 42 is fixedly installed on the telescopic end of the limiting cylinder 43. The clamping mechanism includes a clamping cylinder 36 fixedly installed on the inner wall of one corner of the flipping frame 32, and a clamping plate 37 is fixedly installed on the telescopic end of the clamping cylinder 36.

[0025] The implementation principle of this embodiment is as follows: When fixing the door leaf to the flipping frame 32 for subsequent flipping processing, the door leaf to be processed is first accurately transferred to the inner clamping area of ​​the flipping frame 32 through the coordinated cooperation of the pre-transfer and positioning mechanisms, ensuring that the edge of the door leaf is aligned with the preset clamping reference line of the flipping frame 32; at this time, the clamping cylinders 36 symmetrically arranged at the four corners of the flipping frame 32 are activated, and the cylinder piston rods extend synchronously and push the clamping plates 37 fixed thereto to extend closer to the door leaf until the anti-slip contact end face of the clamping plate 37 is tightly fitted with the edges of the four corners of the door leaf, thereby achieving multi-point firm clamping and positioning of the door leaf, preventing the door leaf from shifting or falling off during the subsequent flipping process; when it is necessary to drive the flipping frame 32 to perform a flipping action, the flipping motor 34 starts and outputs torque, driving the worm gear 3 connected to it. 5. The worm gear 35 rotates, and since the worm wheel 33 forms a self-locking meshing transmission pair, the rotational power of the worm gear 35 can be efficiently transmitted to the worm wheel 33, thereby driving the shaft fixed to the worm wheel 33 and the flipping frame 32 fixed on the shaft to rotate synchronously to meet the adjustment requirements of different processing angles of the door leaf. When the flipping frame 32 drives the door leaf to the loading / unloading station or the target station after processing, the pre-installed limit cylinder 43 is immediately activated. Its piston rod extends and pushes the limit insertion rod 44 to accurately insert into the limit hole 42 of the corresponding station on the limit frame 41. The rigid cooperation between the insertion rod and the limit hole 42 realizes the mechanical locking and limit of the flipping frame 32, ensuring that the flipping frame 32 always maintains a stable posture during loading / unloading operations and processing, providing reliable structural support for the smooth loading and unloading and high-precision processing of the door leaf.

[0026] Example 4: Based on Example 1, this example discloses an adaptive flipping device, such as... Figure 1 , Figure 6 and Figure 7 As shown, the lifting assembly includes four guide frames 51 fixedly installed on the top surface of the support plate 11 at a position inside the bracket 13. Guide columns 52 are slidably installed on the inner wall of the guide frames 51. Lifting plates 53 are fixedly installed on the top of the four guide columns 52. The lifting plates 53 are located directly below the tilting frame 32. A lifting motor 54 is fixedly installed on the top surface of the support plate 11 through a mounting seat. A lifting gear 55 is fixedly installed on the output end of the lifting motor 54. A connecting column 56 is fixedly installed on the bottom surface of the lifting plate 53. A lifting rack 57 that meshes with the lifting gear 55 is fixedly installed on the side of the connecting column 56. Two guide grooves 58 are symmetrically opened on the top surface of the lifting plate 53. Two guide blocks 59 that are slidably connected to the guide grooves 58 are symmetrically fixedly installed on the bottom surface of the clamping seat 61 located on the lifting plate 53. A spring 510 is fixedly installed between the side of the guide block 59 and the inner wall of the guide groove 58.

[0027] The implementation principle of this embodiment is as follows: In the operation stage where the door leaf needs to be re-faced, when the flipping frame 32 moves the door leaf with one side already processed to a vertical static state, the lifting motor 54 starts and drives the lifting gear 55 connected to its output shaft to rotate synchronously. Since the lifting gear 55 and the vertically arranged lifting rack 57 form a precise meshing pair, the power of the gear rotation is converted into a vertical driving force, which in turn drives the connecting column 56, lifting plate 53 and guide column 52 fixed to the lifting rack 57 to slide smoothly upward along the preset guide frame 51 until the clamping seat 61 on the top surface of the lifting plate 53 moves precisely to the preset clamping area at the bottom of the door leaf; at this time, the push cylinder 66 matched with the clamping seat 61 starts immediately, driving the fixed clamping plate 64 to firmly clamp the bottom of the door leaf. At the same time, the piston rods of the clamping cylinders 36 at the four corners of the flipping frame 32 shorten synchronously, driving the clamping plate 37 to retract and release the door leaf, so that the door leaf is completely freed from the constraint of the flipping frame 32; then the lifting motor 54 is started again and its control is activated. The reverse rotation causes the lifting plate 53, along with the door leaf, to move smoothly down along the guide frame 51, providing ample operating space for the subsequent flipping action of the flipping frame 32. Next, the flipping motor 34 starts, causing the flipping frame 32 to rotate 180° counterclockwise. During this rotation, the door leaf's position relative to the flipping frame 32 changes from its initial left side to its right side. Simultaneously, the flipping frame 32 can push the door leaf, causing the clamping seat 61 on the lifting plate 53 to slide and adjust the door leaf's position along the guide groove 58. After the flipping frame 32 completes its 180° rotation and reaches the target position, the lifting motor 54 starts again, moving the lifting plate 53 upwards until the door leaf accurately falls into the inner clamping area of ​​the flipping frame 32. Finally, the clamping cylinders 36 at the four corners of the flipping frame 32 restart, causing the clamping plate 37 to extend and firmly clamp the door leaf. The pushing cylinder 66 on the lifting plate 53 simultaneously releases the door leaf. At this point, the door leaf has been flipped and stably fixed to the flipping frame 32, ready for processing on the other side.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
