Automatic plate turning machine with limiting function

Abstract

This invention relates to an automatic flipping machine with a limiting function, belonging to the field of sheet metal processing technology. It includes a machine body with two rotating seats mounted on it. A conveying mechanism is installed between the two rotating seats. Two guide rails are arranged above the conveying mechanism, and telescopic cylinders are respectively mounted on the two guide rails. Each telescopic cylinder is connected to an assembly frame, and a swinging mechanism is installed inside the assembly frame. This automatic flipping machine with a limiting function uses a buffer pad on the limiting plate to contact the sheet metal for assisted positioning. It can effectively control the pressure between the pressure plate and the sheet metal, avoiding surface damage caused by excessive force provided by the limiting mechanism. For thinner sheets or sheets with irregular shapes such as beveled edges, the suction cups at different positions provide good limiting effect, preventing deformation or displacement of the sheet metal due to asynchronous application of pressure forces, thus improving the efficiency and positional accuracy of sheet metal flipping.

Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, and specifically to an automatic flipping machine with a limiting function. Background Technology

[0002] Panel processing is a core foundational process in many industries, including furniture manufacturing, building decoration, and machinery equipment. It encompasses a series of key processing steps such as cutting, grinding, coating, and printing. Panel flipping is a crucial step in ensuring consistent processing quality on both sides of the workpiece. In traditional production models, panel flipping is mostly done manually, which is not only labor-intensive and inefficient but also prone to causing scratches, edge damage, or positional shifts due to uneven force or improper operation, thus affecting the accuracy of subsequent processing. As industrial production transforms towards automation and high efficiency, automatic panel flipping machines are becoming increasingly popular as core equipment to replace manual labor in the automatic conveying, fixing, and flipping of panels. Through the coordinated operation of mechanical structures, they effectively reduce labor costs and improve production speed, becoming an indispensable key component of modern panel processing production lines.

[0003] Existing automatic flipping machines typically use rigid clamping mechanisms for limiting positions. When dealing with thin sheets, excessive pressure can easily cause deformation and scratches or wear on the sheet surface, affecting the product's appearance quality. Furthermore, when dealing with sheets with beveled edges or irregular shapes, it is difficult to achieve precise positioning. The sheets are prone to slippage during the flipping process, and positional deviations after flipping affect subsequent conveying, requiring additional sheet correction and reducing overall production efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an automatic flipping machine with a limiting function to solve the problems in the prior art that the rigid fixing can easily cause deformation or surface damage to the board, and that irregular boards are prone to slippage during the flipping process.

[0005] This invention is achieved through the following technical solution: An automatic flipping machine with a limit function includes a machine body, on which two rotating seats are aligned and installed. A conveying mechanism is installed between the two rotating seats. Two guide rails are provided above the conveying mechanism. Telescopic cylinders are respectively provided on the two guide rails. The two telescopic cylinders are respectively connected to an assembly frame. A swing mechanism is provided inside the assembly frame. The upper surface of the assembly frame is symmetrically provided with multiple through slots. Multiple movable rods are slidably passed through the assembly frame. Each of the multiple movable rods has a stop block fixedly connected to its top. Each of the multiple movable rods is fitted with a spring. Each of the multiple movable rods has a limit plate fixedly connected to its bottom. The upper surface of each of the multiple limit plates is connected to the bottom of the corresponding spring. The bottom of each limit plate is provided with a buffer pad.

[0006] Furthermore, the machine body includes two aligned frames, with multiple crossbars fixedly connected to the bottom of the two frames. A drive motor is installed at one end of each crossbar, and a detector is installed at the other end of each crossbar. Each of the two frames has an auxiliary frame at its bottom, and auxiliary wheels are installed on both sides of each of the two auxiliary frames.

[0007] Furthermore, both of the rotating seats are configured as annular seats, and grooves are provided on the outer walls of both annular seats, with toothed rings respectively provided in the two grooves; A fixing rod is connected between the two rotating seats, and multiple mounting seats are respectively arranged on the two rotating seats.

[0008] Furthermore, each of the two auxiliary frames is provided with a drive wheel, and each of the two drive wheels has multiple teeth evenly spaced on its sidewall. Each of the two drive wheels meshes with a corresponding gear ring. One of the drive wheels is connected to the output shaft of the drive motor via a key, and the other drive wheel is connected to the detector via a key. The auxiliary wheels abut against the sidewalls of the rotating seats corresponding to their respective positions.

[0009] Furthermore, the conveying mechanism includes two symmetrically arranged vertical plates, and the side walls of the two vertical plates are detachably connected to the mounting base by multiple sets of bolts. Two sets of conveying rollers are aligned between the two vertical plates. The two ends of the two sets of conveying rollers are connected by a transmission belt. Multiple tensioning wheels are arranged between the two transmission belts, and guide wheels are arranged between the two sets of conveying rollers.

[0010] Furthermore, one end of each of the two guide rails is connected to a mounting block, the other end of each of the two guide rails is respectively connected through to a rotating base, and a servo motor is respectively installed at one end of each of the two guide rails extending outside the rotating base; Each of the two guide rails is equipped with a slider.

[0011] Furthermore, the top of the telescopic cylinder is fixedly connected to the bottom of the slider via multiple connecting rods, and the telescopic end of the telescopic cylinder is fixedly connected to a connecting seat, which is located on the top of the assembly frame.

[0012] Furthermore, the swing mechanism includes two gears disposed inside the assembly frame, and the two gears mesh with each other. Support rods are respectively provided through the two gears, and both ends of the two support rods are rotatably connected to the inner wall of the assembly frame. A rotary cylinder is installed on the side wall of the assembly frame, and the output end of the rotary cylinder is connected to one of the support rods. Each of the two support rods is equipped with a pressure plate.

[0013] Furthermore, two collars are fixedly connected to one end of the pressure plate, the collars are disposed on both sides of the gear, and the collars are fixedly connected to the support rod; a roller is embedded at the other end of the pressure plate. The pressure plate is embedded with multiple suction cups.

[0014] The beneficial effects of this invention are as follows: This automatic flipping machine with a limiting function uses a movable rod and spring to move a limiting plate, allowing the buffer pad on the limiting plate to contact the plate for auxiliary positioning. This effectively regulates the pressure between the pressure plate and the plate, preventing damage to the plate surface caused by excessive force from the limiting mechanism. After flipping, the spring's elastic return pushes the limiting plate, allowing the suction cup to quickly separate from the plate, ensuring stable positioning after separation. The assembly frame continues to move downwards, working in conjunction with a rotating cylinder to bring the rollers at the end of the pressure plate into contact with the plate surface, ultimately ensuring a tight fit between the suction cup and the plate for fixation. For thinner plates or plates with irregular shapes such as beveled edges, the use of suction cups at different positions for targeted adsorption provides good limiting effect, preventing deformation or displacement of the plate due to asynchronous applied pressure, thus improving the efficiency and positioning accuracy of plate flipping.

These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0023] Please see Figure 1 and Figure 2 This invention provides a technical solution: an automatic flipping machine with a limiting function, comprising a body 1, the body 1 including two aligned frames 11, the bottom of the two frames 11 being fixedly connected to multiple crossbars 12, one end of the crossbars 12 being equipped with a drive motor 121, and the other end of the crossbars 12 being equipped with a detector 122, the bottom of the two frames 11 being respectively provided with auxiliary frames 13, the two auxiliary frames 13 being respectively equipped with auxiliary wheels 131 on both sides, two rotating seats 2 being aligned and installed on the body 1, both rotating seats 2 being configured as annular seats, the outer walls of the two annular seats being provided with grooves, the two grooves being respectively provided with toothed rings 21, the two rotating seats 2 being connected together by a fixing rod 22, the two rotating seats 2 being respectively provided with multiple mounting seats 23, the two auxiliary frames 13 being respectively provided with drive wheels, the two... Each drive wheel has multiple teeth evenly spaced on its sidewall, and two drive wheels mesh with corresponding gear rings 21. One drive wheel is connected to the output shaft of the drive motor 121 via a key, and the other drive wheel is connected to the detector 122 via a key. Multiple auxiliary wheels 131 abut against the sidewalls of the rotating seat 2 at their corresponding positions, making the rotating seat 2 more stable and less prone to deviation during rotation. It should be noted that when the drive motor 121 is started, the output shaft of the drive motor 121 will drive the drive wheels to rotate synchronously. The drive wheels, in turn, drive the rotating seat 2 to rotate through meshing with the gear rings 21, thereby realizing the rotation action of the flip plate. At the same time, the detector 122 can determine the rotation angle and speed of the rotating seat 2 based on the rotation of the drive wheels, and then feed the information back to the control system to achieve precise control of the flip plate action.

[0024] Reference Figure 3A conveying mechanism 3 is installed between the two rotating seats 2. The conveying mechanism 3 includes two symmetrically arranged vertical plates 31, and the side walls of the two vertical plates 31 are detachably connected to the mounting base 23 by multiple sets of bolts. Two sets of conveying rollers 32 are aligned between the two vertical plates 31. The two ends of the two sets of conveying rollers 32 are connected by transmission belts 33. Multiple tensioning wheels 34 are arranged between the two transmission belts 33. Guide wheels 35 are arranged between the two sets of conveying rollers 32. Furthermore, a suitable gap is reserved between the two sets of conveying rollers 32, so that the plate can be transported to the machine body 1 by an external conveyor belt. Then, the motor drives the multiple conveying rollers 32 to rotate synchronously, and finally moves the plate to a suitable position on the machine body 1. The swing mechanism 7 arranged above limits the plate.

[0025] Reference Figure 2 and Figure 4 Two guide rails 4 are provided above the conveying mechanism 3. One end of the two guide rails 4 is connected to a mounting block. The other end of the two guide rails 4 is connected to the rotating seat 2. Servo motors 41 are installed on the ends of the two guide rails 4 that extend outside the rotating seat 2. Slider 42 is provided on the two guide rails 4. Telescopic cylinders 5 are provided on the two guide rails 4. The two telescopic cylinders 5 are connected to the assembly frame 6. The top of the telescopic cylinder 5 is fixedly connected to the bottom of the slider 42 through multiple connecting rods 51. The telescopic end of the telescopic cylinder 5 is fixedly connected to the connecting seat 52, and the connecting seat 52 is located on the top of the assembly frame 6. It should be noted that when flipping the board, the servo motors 41 on both sides can be started according to the size of different batches of boards to adjust the position of the slider 42 on the guide rail 4, thereby adjusting the distance between the telescopic cylinders 5 on both sides, ensuring that the swing mechanism 7 below the telescopic cylinder 5 is located at both ends of the board, which is convenient for processing boards of different lengths and shapes.

[0026] Reference Figure 5 and Figure 6 The upper surface of the assembly frame 6 is symmetrically provided with multiple through slots 61. The upper end of the suction cup 723 is connected to multiple flexible tubes. The corresponding flexible tubes can be placed in the through slots 61 to avoid obstruction when the pressure plate 72 swings. Multiple movable rods 62 are slidably passed through the assembly frame 6. The top of each movable rod 62 is fixedly connected to a stop block 621. Each movable rod 62 is fitted with a spring 622. The bottom of each movable rod 62 is fixedly connected to a limit plate 63. The upper surface of each limit plate 63 is connected to the bottom of the corresponding spring 622. The bottom of the limit plate 63 is provided with a buffer pad 631.

[0027] Specifically, when flipping the sheet material, the telescopic cylinder 5 is activated. The telescopic end of the cylinder 5 drives the assembly frame 6 to move downwards, eventually bringing the limiting plate 63 and the buffer pad 631 into contact with the surface of the sheet material. Continuing to move downwards will drive the movable rod 62 upwards. At this time, the spring 622 is in a compressed state, which can apply a certain preload to the sheet material, preventing it from sliding on the conveyor roller 32. At the same time, it can assist the suction cup 723 on the subsequent pressure plate 72 to fit tightly with the sheet material, preventing a decrease in the accuracy of the limit when handling thin or irregular sheets. Furthermore, after the flipping is completed, the suction cup 723 adheres to the sheet material. As the assembly frame 6 moves upwards, the compressed spring 622 releases its elastic potential energy. Relying on the downward pressure of the limiting plate 63 and the buffer pad 631, the suction cup 723 quickly separates from the sheet material, ensuring that the sheet material remains in its original position after being removed from the suction cup 723. This improves the accuracy of the conveying after flipping, avoids the need to readjust the sheet material position on the subsequent conveyor belt, and improves work efficiency.

[0028] Reference Figures 7 to 9 The assembly frame 6 is equipped with a swing mechanism 7. The swing mechanism 7 includes two gears 71 inside the assembly frame 6, and the two gears 71 mesh with each other. Support rods 711 are respectively provided through the two gears 71. Both ends of the two support rods 711 are rotatably connected to the inner wall of the assembly frame 6. A rotary cylinder 712 is installed on the side wall of the assembly frame 6, and the output end of the rotary cylinder 712 is connected to one of the support rods 711. Pressure plates 72 are respectively provided on the two support rods 711. Two collars 721 are fixedly connected to one end of the pressure plate 72. The collars 721 are located on both sides of the gear 71 and are fixedly connected to the support rod 711. Rollers 722 are embedded in the other end of the pressure plate 72. Multiple suction cups 723 are embedded in the pressure plate 72.

[0029] It should be noted that in the initial state, the rotary cylinder 712 controls the swing of the pressure plates 72 on both sides to maintain an appropriate angle between the two pressure plates 72. During the process of the telescopic cylinder 5 driving the assembly frame 6 to move downward as a whole, the output end of the rotary cylinder 712 drives the gear 71 to rotate. With the downward movement of the assembly frame 6, the two pressure plates 72 extend to both sides. The rollers 722 at the ends of the two pressure plates 72 contact the surface of the plate and roll, improving the stability of the pressure plates 72 during movement. Finally, the suction cup 723 is tightly attached to the surface of the plate, and the externally connected pump group is activated to limit the suction cup 723 to the plate. This can avoid the deformation caused by excessive force applied to thinner plates due to direct downward pressure. At the same time, it can be used to specifically position irregularly shaped plates to prevent them from moving during the flipping process.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
