Description

Technical Field

[0001] This utility model relates to the field of nickel mesh production and processing, specifically to an automatic gripping device for multi-piece nickel mesh based on magnetic attraction. Background Technology

[0002] The transfer of nickel mesh is a crucial process connecting various production steps, and its efficiency and quality directly affect the continuity of the entire production line and the final product quality. Currently, the industry still widely relies on traditional manual gripping or simple mechanical-assisted gripping methods for nickel mesh transfer. These existing technologies have revealed many unavoidable defects in practical applications, severely restricting the improvement of production efficiency and the stability of product quality.

[0003] Traditional manual handling requires operators to manually move stacked nickel meshes one by one to designated workstations. This is not only labor-intensive but also limits the number of meshes that can be moved at a time, making it difficult to meet the efficiency requirements of large-scale production. More importantly, during manual handling, the operator's hands are in direct contact with the nickel mesh, which can easily lead to deformation due to uneven force or contamination of the mesh surface due to oil or impurities from the hands, thus affecting the accuracy of subsequent processing steps and the performance of the finished nickel mesh. Even when some companies use simple mechanical auxiliary handling devices, such as pneumatic grippers, there are still significant shortcomings: pneumatic grippers need to grasp the edges of the nickel mesh to achieve gripping. For thin nickel meshes, excessive gripping force can cause wrinkles and deformation at the edges, while insufficient gripping force can easily cause the nickel mesh to fall off during transport. At the same time, the gripping range of pneumatic grippers is fixed, making it difficult to adapt to nickel meshes of different sizes and thicknesses. This results in poor versatility, requiring frequent changes of grippers for different specifications of nickel meshes, further increasing production auxiliary time and equipment maintenance costs.

[0004] The existing equipment has a low level of automation. Manual intervention is required for tasks such as gripping position calibration and gripping motion control. It is difficult to link with the automated nickel mesh production line and cannot meet the requirements of modern production for continuous process connection and stable operation, thus restricting the improvement of the overall automation level of nickel mesh production.

[0005] For the reasons mentioned above, it is necessary to propose an automatic multi-plate nickel mesh gripping device based on magnetic attraction to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to overcome the defects in the existing technology and provide an automatic gripping device for multi-piece nickel mesh based on magnetic attraction.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: A magnetic attraction-based multi-piece nickel mesh automatic gripping device includes a main body with a frame structure. At least one moving guide rail is provided on the inner or outer wall of the frame, and the moving guide rail is arranged in a vertical direction. The lifting mechanism is slidably mounted on the moving guide rail and is controlled by the drive mechanism to move vertically up and down. The magnetic gripping assembly includes a mounting frame and an electromagnetic chuck. The electromagnetic chuck is fixed to the lifting mechanism via the mounting frame, so that the magnetic gripping assembly can be adjusted in position according to the lifting mechanism. The electromagnetic chuck grips the nickel mesh through electromagnetic attraction. A protective component is mounted on the lifting mechanism and located below the electromagnetic gripping component. The protective component has the freedom to adjust its longitudinal height on the lifting mechanism, thereby changing the distance between it and the electromagnetic chuck. An isolation structure is hinged on the protective component. The isolation structure is configured to swing horizontally around the hinge as an axis. When the magnetic gripping component attracts the target number of nickel meshes, the isolation structure is controlled to swing horizontally to separate the nickel meshes below.

[0008] Furthermore, the magnetic gripping component has a flexible protective layer on its adsorption surface, and the electromagnetic chuck is a rectangular neodymium iron boron electromagnetic chuck, the size of which matches the nickel mesh to be gripped, and multiple independent magnetic units are evenly distributed on its adsorption surface.

[0009] Furthermore, the drive mechanism includes a servo motor, a ball screw, and a sliding seat. The ball screw is rotatably mounted in the moving guide rail, and the sliding seat is driven by the ball screw to slide along the moving guide rail. The output end of the servo motor is connected to the ball screw.

[0010] Furthermore, the protective assembly includes an electric telescopic cylinder and an adjusting seat. The adjusting seat is slidably mounted on a sliding seat in a vertical direction, and the electric telescopic cylinder is fixedly mounted on the sliding seat. The free end of the electric telescopic cylinder extends and retracts in a vertical direction to control its end connection to the adjusting seat.

[0011] Furthermore, the isolation structure includes a swing arm and a bushing. The adjusting seat is provided with a hollow shaft arranged in the vertical direction for hinged connection with the bushing. The bushing is rotatably mounted on the hollow shaft, and the swing arm is fixedly connected to the bushing and extends in the horizontal direction.

[0012] Furthermore, the isolation structure is also equipped with a mesh pushing structure, which includes a side-opening track, a push block, a spring, a winding part, and a steel wire rope. The swing arm is provided with an open track inside, which is arranged along the axial direction of the swing arm, and the track has an opening on the upper surface of the swing arm. The push block is slidably connected in the open track, and the push block protrudes through the opening and has a contact block. The push block has a spring in the open track on the side near the bushing. The winding part is set on the adjusting seat, and the winding end of the winding part is connected to one end of the steel wire rope. The other end of the steel wire rope passes upward through the hollow shaft and then turns to connect to the push block.

[0013] Furthermore, it also includes an intelligent control system, which is electrically connected to the lifting mechanism and the magnetic gripping component, respectively, receives signals from the infrared positioning sensor and the pressure sensor, adjusts the magnetic attraction strength, and automatically controls the movement of the lifting mechanism and the on / off state of the magnetic attraction unit.

[0014] Furthermore, the surface of the swing arm is covered with a protective layer made of flexible polytetrafluoroethylene with a thickness of 2mm, which is used to reduce the scratching of the nickel mesh during insertion.

[0018] The specific embodiments of this utility model will be further described below with reference to examples. These examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] This utility model discloses an automatic nickel mesh picking device based on magnetic attraction for multiple pieces. Specifically, the device picks up the nickel mesh through a collaborative logic of "stable support - precise lifting - magnetic attraction - protective isolation - intelligent control".

[0020] The main body 1 of the device can be made of carbon steel welded frame for stable support and adaptation to external moving guide rail 2. At least one vertical moving guide rail 2 is provided inside or on the outer wall of the frame. The lifting mechanism is vertically installed on one side of the main body 1 and moves up and down along the track of the main body 1. The vertical moving guide rail 2 provides a stable moving path for the lifting mechanism, giving the main body 1 good support and guiding functions. The moving guide rail 2 can be optionally installed on the inner or outer wall, further expanding the flexibility of space utilization of the main body 1. The appropriate guide rail installation position can be selected according to the nickel mesh size and gripping space requirements in the actual production scenario, ensuring the stability of the lifting mechanism during movement. In this embodiment, only the example of setting the moving guide rail 2 on the outer wall of the frame is taken. Figure 1-3 As shown.

[0021] In this embodiment, the lifting mechanism consists of a servo motor 8, a ball screw 9, and a sliding seat 10. The servo motor 8 drives the ball screw 9 to rotate, causing the sliding seat 10 to move along the track. The ball screw 9 is rotatably mounted in the moving guide rail 2, with its upper and lower ends rotatably connected to the frame. The servo motor 8 drives the ball screw 9 to rotate through a reduction mechanism. The sliding seat 10 is driven by the ball screw 9 to slide along the moving guide rail 2. The output end of the servo motor 8 is connected to the ball screw 9. The high-precision driving characteristics of the servo motor 8 and the high-efficiency transmission capability of the ball screw 9 can meet the requirements for precise height control when picking up nickel mesh, ensuring that the lifting mechanism can drive the magnetic gripping component 3 to achieve stable vertical lifting according to the height requirements of nickel mesh grabbing and transfer. At the same time, the sliding cooperation between the sliding seat 10 and the moving guide rail 2 ensures smooth lifting without jamming.

[0022] The magnetic gripping assembly 3 includes a mounting frame 4, an electromagnetic chuck 5, and positioning components. The electromagnetic chuck 5 is embedded in the bottom of the mounting frame 4, with a flexible protective layer 7 on its adsorption surface. It is a rectangular neodymium iron boron electromagnetic chuck 5 with evenly distributed independent magnetic units. The electromagnetic chuck 5 is fixed to the lifting mechanism via the mounting frame 4. The flexible protective layer 7 on its adsorption surface, the rectangular neodymium iron boron electromagnetic chuck 5 with dimensions matching the nickel mesh to be gripped, and multiple independent magnetic units evenly distributed on its adsorption surface prevent scratches caused by direct contact between the electromagnetic chuck 5 and the nickel mesh. The design of the rectangular neodymium iron boron electromagnetic chuck 5 and the independent magnetic units allows for precise adjustment of the magnetic strength to adapt to the control of nickel meshes of different thicknesses. It can flexibly adjust the magnetic strength according to the thickness of the nickel mesh to ensure stable gripping of nickel meshes of different specifications. The electromagnetic chuck 5 is fixedly connected to the lifting mechanism via the mounting frame 4, allowing the position of the magnetic gripping assembly 3 to be controlled by adjusting the position of the lifting mechanism.

[0023] The protective component 6 is located directly below the magnetic suction component, forming a physical barrier after the magnetic suction component attracts the nickel mesh. The protective component 6 is mounted on the lifting mechanism and located below the electromagnetic gripping component. It has the freedom to adjust its vertical height and also features a horizontally swingable isolation structure. This structure separates the nickel mesh below the magnetic suction component 3 after it has attracted the target number of nickel meshes. In use, the electromagnetic chuck 5 is adjusted to attract the corresponding number or thickness of nickel meshes. Then, the protective component 6 is used to physically isolate the nickel mesh below. Through the optimized vertical height design, the distance between the isolation structure and the electromagnetic chuck 5 can be flexibly adjusted according to the thickness and stacking height of the nickel mesh, adapting to isolation requirements in different scenarios. Furthermore, the horizontally swingable isolation structure further enhances its flexibility and adaptability to nickel meshes. In addition, the surface of the swing arm 13 in the protective component 6 is covered with a 2mm thick flexible polytetrafluoroethylene protective layer 22, further ensuring the integrity of the nickel mesh during the isolation process.

[0024] In terms of intelligent control system, the intelligent control system takes PLC as the core, links sensors and various components, realizes the control logic of adsorption position calibration, real-time pressure monitoring and lifting, and magnetic suction action linkage control, and ensures that the components of the device can work together under intelligent control, realize the automation of nickel mesh grabbing and transfer, improve production continuity and operation safety, and reduce labor costs.

[0025] The working principle of this device can be summarized as follows: Under the overall coordination of the intelligent control system, the relative position of the main body 1 and the nickel mesh stack is first calibrated by an infrared positioning sensor to ensure the precise movement of each component. Then, the intelligent control system commands the lifting mechanism to start, and the servo motor 8 in the drive mechanism drives the ball screw 9 to rotate, causing the sliding seat 10 to move downwards along the vertical moving guide rail 2 on the main body 1. This, in turn, causes the magnetic gripping component 3, fixed to the sliding seat 10 by the mounting bracket 4, to move downwards synchronously until the electromagnetic chuck 5 approaches the nickel mesh to be gripped. At this point, the intelligent control system adjusts the magnetic strength of each independent magnetic unit on the electromagnetic chuck 5 according to the thickness of the nickel mesh to be gripped, so that the electromagnetic chuck 5 generates an appropriate electromagnetic attraction force to attract the target number of nickel meshes. Simultaneously, the pressure sensor on the back of the electromagnetic chuck 5 detects the adsorption pressure in real time. When the pressure reaches a preset threshold, confirming that the nickel mesh is stably adsorbed, the signal is fed back to the intelligent control system. Next, the intelligent control system commands the protective component 6 to operate. On one hand, it adjusts the longitudinal height of the adjusting seat 12 via the electric telescopic cylinder 11 to place the isolation structure in a suitable working position. On the other hand, it controls the swing drive structure to drive the driven bevel gear 23 to mesh and rotate with the driving bevel gear 24, thereby causing the bushing 14 to rotate around the hollow shaft 15 on the adjusting seat 12, which in turn drives the swing arm 13 to swing horizontally and insert between the adsorbed nickel mesh and the stacked nickel mesh below, completing the separation between the picked-up nickel mesh and the lower nickel mesh. The lifting mechanism is restarted, driving the magnetic gripping component 3 and the adsorbed nickel mesh to move upward until a suitable transfer height is reached. Then, with the cooperation of the external moving guide rail 2 (adapted and connected to the main body 1 of the device), the entire device or the magnetic gripping component 3 is moved to the target transfer position. Upon reaching the target position, the intelligent control system instructs the electromagnetic chuck 5 to de-energize and release the nickel mesh. Simultaneously, it controls the isolation structure of the protective component 6 to swing back and retract. The lifting mechanism drives the magnetic gripping component 3 to reset, preparing for the next gripping operation. The entire process requires no manual intervention, realizing automated operation of gripping and transferring multiple pieces of nickel mesh at a time. This significantly improves the efficiency of nickel mesh transfer and the stability of product quality, meeting the demand for efficient and high-quality transfer in nickel mesh production.

[0026] It is understandable that during pickup, the swing arm 13 in the protective assembly 6 swings to one side, with the bottom of the electromagnetic chuck 5 open, allowing direct contact and pickup of the nickel mesh. When the electromagnetic chuck 5 picks up the nickel mesh, a 2-5mm edge gap is formed between the nickel mesh to be picked up and the lower nickel mesh. The height position of this edge gap can be captured by sensors such as a camera, and the height position of the adjusting seat 12 can be controlled by the electric telescopic cylinder 11, so that the swing arm 13 is located at the gap. It is understandable that the two sides of the swing arm 13 in this embodiment are thin-walled structures (smaller than the gap), so the drive bevel gear 24 is used to mesh with the driven bevel gear 23, which can control the swing arm 13 to swing laterally and sweep between the two nickel meshes from the edge gap, thereby separating them.

[0027] Furthermore, since the swing arm 13 is controlled to swing horizontally, after it separates the nickel mesh from the lower side, the swing arm 13 can be controlled to rotate from the side to directly below the nickel mesh to support it, preventing the nickel mesh from falling during the transfer process. In addition, this embodiment also includes a push block 17 pulled by a wire rope 20. The spring 18 always applies a pushing force to the push block 17 away from the bushing 14. It can be understood that the wire rope 20 keeps pulling the push block 17, thereby compressing the spring 18, while the wire rope 20 is controlled by the winding section 19 to perform winding or unwinding operations. When winding, spring 18 is further compressed. When unwinding, spring 18 causes push block 17 to move away from bushing 14. Its function is to release the nickel mesh when it needs to be released from the device to another position. In addition to the aforementioned method of de-energizing the electromagnetic chuck 5, it also has the function of transferring between pickup devices. Specifically, when the device moves to the transfer position, swing arm 13 is moved below the nickel mesh. The power supply to electromagnetic chuck 5 can be reduced to weaken the magnetic attraction (or the power can be directly de-energized). Then, the winding part 19 unwinds the nickel mesh. Under the action of spring 18, push block 17 moves along open track 16, so that contact block 21 abuts against the edge of the nickel mesh. Under the action of spring 18, the nickel mesh is further pushed outward horizontally a distance, so that the outer edge of the nickel mesh is exposed. Then, the next tooling can clamp the edge of the nickel mesh to pick it up and relay the force, thereby realizing the transfer of the nickel mesh between different workstations.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
