Description

Technical Field

[0001] This invention relates to the field of lifting and conveying devices, specifically to a metal processing lifting and conveying device and method. Background Technology

[0002] As is well known, metal processing lifting and conveying devices are auxiliary devices that integrate lifting and conveying functions to realize the automated flow of workpieces, loading and unloading, and cross-station transfer.

[0003] A search revealed that Chinese patent application CN202122044740.3 discloses a rapid lifting and conveying device for machining. The device generally includes a base plate and a lifting and conveying assembly. A control switch assembly is mounted on the side of the base plate. The lifting and conveying assembly comprises a fixed frame, a sliding frame, a mounting frame, and a belt conveyor. The fixed frame is fixed to the front end of the side of the base plate. A sliding frame is fitted onto the side of the fixed frame. A mounting frame is fixed to the rear side of the sliding frame. The belt conveyor is installed inside the mounting frame. In use, the workpiece is first placed on the upper side of the belt conveyor. When connecting and docking with the conveying equipment, the starter motor drives the gears to rotate, causing the sliding frame to move upward. The upward movement of the sliding frame moves the mounting frame, the belt conveyor, and the workpiece placed on the belt conveyor upward. Once the belt conveyor reaches the position corresponding to the conveying equipment, starting the belt conveyor allows for convenient workpiece transfer.

[0004] Although the aforementioned existing technical solutions can achieve auxiliary conveying of workpieces, it is clear from their operating instructions that the workpieces need to be placed on the upper side of the belt conveyor before subsequent conveying operations can begin. Therefore, during operation, they require assistance from operators or other equipment, and their practicality and functionality need to be further improved. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a metal processing lifting and conveying device and method. While being able to complete the auxiliary lifting and conveying and position adjustment of sheet metal, it simultaneously realizes the integrated operation of sheet metal picking, flipping and conveying processes, greatly expanding the comprehensive function of sheet metal position adjustment, and significantly improving the overall practicality and adaptability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal processing lifting and conveying device, comprising a mounting frame, an adjusting component, and a conveying and gripping component. The adjusting component is mounted on the mounting frame. The conveying and gripping component includes a main mounting frame, which is mounted on the adjusting component. Two opposing frames are slidably connected to the main mounting frame. A opposing drive component is mounted on the main mounting frame to drive the synchronous relative movement of the two opposing frames. The conveying and gripping component includes a first gripping cylinder and a second gripping cylinder, which are respectively mounted on the two opposing frames. A first servo motor and a second servo motor are respectively mounted on the two opposing frames. The first servo motor and the second servo motor are respectively used to drive the first gripping cylinder and the second gripping cylinder to rotate. A first gripping mechanism and a second gripping mechanism are respectively installed inside the first gripping cylinder and the second gripping cylinder.

[0007] Furthermore, the first gripping mechanism includes multiple first synchronization bars, each slidably connected within the first gripping cylinder. Multiple first suction cups are mounted on each of the multiple first synchronization bars. The first gripping cylinder has multiple first through holes, each matching one of the first suction cups. Each of the multiple first synchronization bars is fixedly connected to a first storage spring, which is also fixedly connected within the first gripping cylinder. The second gripping mechanism includes multiple second synchronization bars, each slidably connected within the second gripping cylinder. Multiple second suction cups are mounted on each of the multiple second synchronization bars. The second gripping cylinder has multiple second through holes, each matching one of the second suction cups.

A first pneumatic component and a second pneumatic component are respectively disposed within the first and second gripping cylinders. The first pneumatic component provides driving force for the first synchronization bars and the first suction cups, and the second pneumatic component provides driving force for the second synchronization bars and the second suction cups.

[0008] Furthermore, both the first and second pneumatic components include fixed cylinders, which are respectively fixedly connected to the two opposing frames. Each fixed cylinder is also fixedly connected to a mounting frame, and each mounting frame is fixedly connected to an elastic bladder. Each elastic bladder is fixedly connected to a first adjusting frame and a second adjusting frame, which are respectively matched with a first synchronization bar and a second synchronization bar. Each fixed cylinder has an internal gas channel and an external gas channel, which communicate with the two elastic bladders. The first adjusting frame has multiple first vent holes, which provide a negative pressure environment for the first suction cup. The second adjusting frame has multiple second vent holes, which provide a negative pressure environment for the second suction cup. Each of the multiple first vent holes communicates with one internal gas channel located within the first gripping cylinder, and each of the multiple second vent holes communicates with another internal gas channel.

[0009] Furthermore, the displacement drive assembly includes a third servo motor and two synchronous racks. Both synchronous racks are slidably connected to the mounting main frame. The third servo motor is mounted outside the mounting main frame. A drive gear is mounted on the output shaft of the third servo motor. Both synchronous racks mesh with the drive gear. The two synchronous racks are respectively fixedly connected to the two displacement frames.

[0010] Furthermore, the adjustment assembly includes a rotating frame and a fourth servo motor. The rotating frame is rotatably connected to the mounting frame, and the fourth servo motor is installed within the mounting frame.

[0011] Furthermore, the power parallel component includes a sixth servo motor, an inner parallel rod, and an outer parallel rod.

The sixth servo motor is mounted on the rotating frame, and its output shaft is connected to the inner parallel rod.

[0012] Furthermore, the main mounting frame has two slots, each containing a quick-connect pipe.

The inner bend extension head is connected to the inner gas channel, and the outer bend extension head is connected to the outer gas channel.

[0013] Furthermore, a spur gear is mounted on the output shaft of the fourth servo motor, and the spur gear meshes with a spur gear ring, which is fixedly mounted outside the rotating frame.

[0014] Furthermore, the mounting frame is externally fixedly connected to two side extension strips.

[0015] A conveying method for a metal processing lifting and conveying device includes the following steps: S1. Start the overall device, and drive the conveying and gripping components to achieve lifting and horizontal position adjustment by adjusting the operation of the components. Combine the specifications and dimensions of the metal sheet to be processed, the actual position parameters of the loading and unloading stations, and calibrate the corresponding working height and horizontal coordinates of the main frame, so that the two sets of shifting frames, the first gripping cylinder and the second gripping cylinder can form a position adjustment between the gripping point and the target point. S2. Start the opposing drive assembly on the main frame to drive the two sets of opposing frames to slide synchronously relative to each other, thereby adjusting the center distance between the first gripping cylinder and the second gripping cylinder so that the first gripping cylinder and the second gripping cylinder match the size and specifications of the material to be processed. Then start the air pump assembly that is matched with the first and second gripping mechanisms, and drive the two sets of gripping mechanisms to run by relying on the power of the air pump to complete the adsorption, clamping and fixing of the material. S3. The control and adjustment components operate to lift and move the main frame, transferring the clamped and fixed plate from the loading station to the designated processing station. After the plate arrives at the target processing station, the air pump power of the first and second gripping mechanisms is turned off, the adsorption limit of the mechanism on the plate is released, and the plate unloading operation is completed. S4. After a single unloading operation is completed, the two sets of opposing frames are driven to slide synchronously in opposite directions by the opposing drive component to complete the spacing reset. At the same time, the adjustment component drives the overall conveying and gripping component to return to the initial standby position. This completes a single metal sheet lifting and conveying operation. The equipment can then enter standby mode and is ready to carry out the next round of sheet conveying operation at any time.

[0016] Compared with the prior art, the present invention provides a metal processing lifting and conveying device and method, which has the following beneficial effects: (1). In this invention, by adjusting the design of the component, on the one hand, it can provide a basic mounting carrier for the conveying and grasping component, and on the other hand, it can give the conveying and grasping component the ability to adjust its spatial position.

[0017] (2). In this invention, the design of the conveying and gripping component can support and convey the metal sheet to be processed, making it easier to complete the lifting and conveying process of the sheet during processing.

[0018] (3). In this invention, by equipping the first gripping mechanism and the second gripping mechanism, the two sets of mechanisms can cooperate to form an adsorption clamping structure for the metal sheet to be processed, thereby realizing the adsorption and gripping of the metal sheet, and the sheet can be flipped and repositioned after gripping.

Two side straightening strips 39 are fixedly connected to the outside of the mounting frame 1 to improve the support stability of the mounting frame 1.

[0025] In this embodiment, the first servo motor 6, the second servo motor 7, the third servo motor 22, the fourth servo motor 26, the fifth servo motor 30, and the sixth servo motor 31 are all commercially available conventional devices known to those skilled in the art. In this invention, we are simply using them without making any improvements to their structure or function. Their setting methods, installation methods, and electrical connection methods can be easily understood by those skilled in the art by following the instructions for use, and will not be described in detail here.

[0026] In summary, the working process of this metal processing lifting and conveying device is as follows: First, the straightening bar 39 is fixedly installed at the designated station on the metal processing production line. Then, the electrical installation and debugging of the equipment are completed. An air intake pump is connected and installed to the inner bending pipe head 35, and an exhaust pump is connected and installed to the outer bending pipe head 36. The air intake pump and exhaust pump together form an external air pump device. The fourth servo motor 26 is started, and the fourth servo motor 26 drives the spur gear ring 38 to rotate through the meshing of the spur gear 37, causing the rotating frame 25 to rotate and change position relative to the mounting frame 1. The sixth servo motor 31 is started, driving the inner parallel rod 32 and the outer parallel rod 33 to rotate synchronously. Relying on the parallel linkage structure, the displacement frame 27 is driven to achieve lifting and horizontal displacement. The main frame 2 is then calibrated and installed. The working height and horizontal position are adjusted to meet the requirements of picking and conveying. The third servo motor 22 is started, which drives the drive gear 24 to rotate, driving the synchronous racks 23 meshing on both sides to slide synchronously relative to each other, thereby driving the two opposing frames 3 to move towards each other. The distance between the first gripping cylinder 4 and the second gripping cylinder 5 is adjusted so that the distance between the first gripping cylinder 4 and the second gripping cylinder 5 is completely adapted to the length and width specifications of the material to be processed. After the distance is adjusted to the correct position, an external air pump is used to draw air into the inner gas channel 18 and supply air to the outer gas channel 19. The air in the outer gas channel 19 will inflate and expand the elastic bladder 15, causing the elastic bladder 15 to expand and extend, pushing the first adjusting frame 16 and the second adjusting frame 17 to push the corresponding first and second adjusting frames 17 respectively. Synchronous bar 8 and synchronous bar 11 overcome the elasticity of the first storage spring 10 and the second storage spring 13, causing the corresponding first suction cup 9 and second suction cup 12 to extend from the first through hole and the second through hole respectively, forming a fit with the metal plate. Subsequently, a negative pressure environment is formed on the end face of the suction cup through the internal gas channel 18, the first vent 20 and the second vent 21. The plate is fixed by the negative pressure adsorption force, completing the automated gripping and clamping of the plate. If the plate needs to be flipped and repositioned during processing, the fifth servo motor 30 can drive the rotating shaft 29 to rotate, driving the mounting frame 2 and the clamped plate to complete the flipping and repositioning of the plate. When the plate needs to be auxiliary conveyed, the plate is first connected to the first gripping cylinder 4 and the second gripping cylinder 5. The relative position between the plates is adjusted so that the plates are above the first gripping cylinder 4 and the second gripping cylinder 5. Then, the suction force of the first suction cup 9 and the second suction cup 12 on the plates is released, and the first suction cup 9 is controlled to retract into the gripping cylinder, and the second suction cup 12 is also controlled to enter the second gripping cylinder 5. Then, the first servo motor 6 and the second servo motor 7 are started simultaneously to drive the first gripping cylinder 4 and the second gripping cylinder 5 to rotate synchronously, driving the auxiliary conveying of the plates until the plates reach the designated work position. After a single conveying and unloading operation is completed, the equipment automatically runs and resets. The third servo motor 22 reverses to drive the two sets of shifting frames 3 to slide back and forth, restoring the initial standard spacing. At the same time, the adjustment components are linked to reset, driving the conveying and gripping components to return to the initial standby position, waiting for the next operation command.

[0027] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.

A conveying method for a metal processing lifting and conveying device, characterized in that, The metal processing lifting and conveying device according to any one of claims 1-9 includes the following steps: S1. Start the overall device, and drive the conveying and gripping components to achieve lifting and horizontal position adjustment by adjusting the operation of the components. Combine the specifications and dimensions of the metal plate to be processed, the actual position parameters of the loading station and unloading station, and calibrate the corresponding working height and horizontal coordinate of the main frame (2) so that the two sets of shifting frames (3), the first gripping cylinder (4) and the second gripping cylinder (5) can form a position adjustment between the gripping point and the target point. S2. Start the offset drive assembly on the main frame (2) to drive the two sets of offset frames (3) to slide synchronously relative to each other, thereby adjusting the center distance between the first gripping cylinder (4) and the second gripping cylinder (5) so that the first gripping cylinder (4) and the second gripping cylinder (5) match the size and specifications of the plate to be processed. Then start the air pump assembly that is matched with the first and second gripping mechanisms, and drive the two sets of gripping mechanisms to run by relying on the power of the air pump to complete the adsorption, clamping and fixing of the plate. S3. Control the operation of the adjustment component to lift and move the main frame (2) to move the clamped plate from the loading station to the designated processing station. After the plate arrives at the target processing station, turn off the air pump power of the first and second gripping mechanisms, release the adsorption limit of the mechanism on the plate, and complete the plate unloading operation. S4. After a single unloading operation is completed, the two sets of opposing frames (3) are driven to slide synchronously in opposite directions by the opposing drive component to complete the spacing reset. At the same time, the overall conveying and grabbing component is driven by the adjustment component to return to the initial standby position. Thus, a single metal sheet lifting and conveying operation is completed, and the equipment can enter the standby state and can carry out the next round of sheet conveying operation at any time.
