Description

Technical Field

[0001] This utility model relates to the field of indexing feeding, specifically to an adjustable-pitch nickel sheet taping indexing feeding device. Background Technology

[0002] Indexing feeders are key equipment in industrial production for achieving intermittent and precise material conveying. They are widely used in the processing and assembly of small precision parts such as electronic components and thin metal sheets. Their core function is to control the material conveying according to a preset step length and rhythm through a specific transmission structure, ensuring that subsequent processing or assembly actions can be precisely coordinated with the material conveying, thereby improving production efficiency and product accuracy. In the field of nickel sheet processing, nickel sheets often need to be conveyed in batches in the form of tape. However, in actual production, the specifications of nickel sheets will vary according to the needs of downstream products. This puts forward the requirement for indexing feeders to have adjustable spacing and adaptability to tapes of different sizes of nickel sheets, so as to avoid frequent replacement of equipment or core components due to changes in nickel sheet specifications, ensure production continuity, and reduce equipment investment costs.

[0003] Existing equipment for nickel sheet taping and conveying suffers from significant shortcomings in adaptability, synchronization accuracy, and operational stability. Regarding specification compatibility, most equipment can only accommodate nickel sheets of a single size. Switching to different widths or thicknesses often requires disassembling and replacing or modifying core components such as the conveyor belt and positioning devices. This is not only cumbersome and time-consuming but also prone to affecting the original accuracy of the equipment during disassembly and assembly, leading to low production changeover efficiency. In terms of synchronization control, some equipment relies on simple mechanical linkages or manual adjustments, making it difficult to achieve precise matching between material handling actions and material conveying pauses, which can easily result in misplacement of nickel sheets. The issues of missing or colliding with the conveyor structure can cause nickel sheet loss and production interruption. In terms of operational stability and maintenance convenience, the transmission components of some equipment lack effective support structures, which can easily lead to radial displacement during long-term operation, affecting the stability of the conveying step length. Insufficient gripping force of the material picking components can easily cause nickel sheets to fall off. Furthermore, the adjustment of conveyor belt tension often requires complex operations, increasing the difficulty and cost of daily equipment maintenance. These problems collectively restrict the efficiency and quality of nickel sheet taping and conveying, making it difficult to meet the needs of large-scale and diversified production. To address these issues, we propose an adjustable-gap nickel sheet taping indexing and feeding device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an adjustable-spacing nickel strip indexing and feeding device, which solves the aforementioned problems.

[0007] Preferably, the feeding execution component further includes a feeding mechanism mounting plate and a feeding transmission bracket. The surface of the feeding mechanism mounting plate has two sets of elongated holes, which are horizontally fitted onto the tops of two adjacent sets of conveyor belt side support columns.

[0009] Preferably, the conveyor belt roller in the conveying assembly is an adjustable tension roller. The conveyor belt side support column has vertical grooves at the positions of the wheel axles at both ends of the conveyor belt roller. The wheel axles of the conveyor belt roller are slidably engaged in the vertical grooves, and an adjusting nut is sleeved on the outside of the wheel axle. By turning the adjusting nut, the conveyor belt roller is driven to move up and down along the vertical groove, thereby adjusting the tension of the conveyor belt.

[0010] Preferably, it also includes a synchronization control component, which includes a photoelectric sensor and a controller. The photoelectric sensor is fixed to the side of the discharge end of the conveyor belt and is used to detect the stopping position of the nickel sheet braiding on the conveyor belt.

[0012] Compared with the prior art, this utility model provides an adjustable-pitch nickel sheet taping and indexing feeding device, which has the following advantages: This adjustable-pitch nickel strip indexing and feeding device offers flexibility in adapting to multiple specifications. Its conveyor belt surface features multiple sets of grooves of varying widths, gradient-distributed along its length, allowing for direct insertion of nickel strips of different sizes. The storage platform can quickly adapt to nickel strips of different thicknesses via adjustable bottom feet. The feeding mechanism mounting plate can also adjust its height along the side support columns of the conveyor belt and slide axially along the conveyor belt rollers. This allows for rapid switching and adaptation of nickel strips of various specifications without disassembling core components, significantly improving the device's versatility and production changeover efficiency. Regarding the synchronous control precision of feeding and conveying, the device is equipped with a synchronous control component. Photoelectric sensors detect the stopping position of the nickel strips on the conveyor belt in real time, and the controller synchronously adjusts the speed of the indexing transmission component motor and the rotation frequency of the feeding drive motor, combined with the indexing plate and indexing wheel... The intermittent rotation step length of the meshing drive stabilizes the conveyor belt, allowing the action of the pick-and-place head in grabbing and transferring nickel sheets to precisely match the rhythm of the conveyor belt's pauses. This significantly reduces the feeding error rate and improves the continuity and accuracy of nickel sheet conveying. Regarding operational stability and ease of maintenance, the device uses rolling bearings within the drive shaft support to fix the outer wall of the driven wheel, effectively limiting radial offset of the drive shaft to ensure transmission stability. The pick-and-place head employs a vacuum suction cup with an annular adsorption groove, combined with an external negative pressure device to enhance the adsorption force on the nickel sheets, reducing nickel sheet drop and loss. Simultaneously, the conveyor belt rollers can be moved up and down along a vertical chute by turning the adjusting nut, facilitating easy adjustment of the conveyor belt tension to prevent slack or excessive tightness from affecting conveying. Overall, this improves the stability of the device's operation, simplifies daily adjustment and maintenance, and reduces equipment operation and maintenance costs. Attached Figure Description

[0024] Working principle: First, the storage platform 20 temporarily stores unbraided nickel sheets. Its bottom is equipped with height-adjustable feet, each containing a fixed rod and an adjusting rod. The fixed rod is vertically welded to the bottom surface of the storage platform 20. The adjusting rod is connected to the internal screw hole of the fixed rod via threads and has an anti-slip rubber pad at its bottom. By turning the adjusting rod, the top surface of the storage platform 20 can be made flush with the surface of the conveyor belt 11, while ensuring that its end face near the feeding actuator corresponds to the starting position of the feeding rotating rod 16, preparing for material retrieval. Subsequently, the indexing transmission assembly is activated and fixed to... The output shaft of the motor 2 at the top of the base 1 drives the coaxial indexing plate 3 to rotate. The indexing plate 3 has a worm-like structure with teeth divided into two sections along the axial direction. One section's axis is parallel to the axis of the indexing plate 3, while the other section is inclined at a specific angle. During its rotation, it meshes with the worm-shaped indexing wheel 4, whose teeth are circumferentially cylindrical protrusions. This drives the transmission shaft 5, which is coaxially fixed at the center of the indexing wheel 4, to rotate. The two ends of the transmission shaft 5 are stabilized by transmission shaft support seats 7. The transmission shaft support seats 7 are fixed to one side of the conveyor belt side support column 8 and have rolling shafts embedded inside. The inner ring is fixed to the outer wall of the driven wheel 6, which can prevent the radial offset of the drive shaft 5. The driven wheels 6 at both ends of the drive shaft 5 rotate with it and mesh with the conveyor belt wheels 10 that are coaxially fixed at both ends of the conveyor belt roller 9 near the drive shaft 5, thereby driving the group of conveyor belt rollers 9 to rotate. In the conveying assembly, the two ends of the conveyor belt roller 9 are rotatably connected between the vertically corresponding conveyor belt side support columns 8, and are tension rollers with adjustable tension. The conveyor belt side support columns 8 have vertical grooves at the corresponding wheel axle positions. The two ends of the wheel axle are slidably engaged in the grooves. Adjusting nuts are fitted on the outer side. Tightening can drive the roller to move up and down to adjust the tension of the conveyor belt 11. The conveyor belt 11 surrounding the conveyor belt roller 9 achieves intermittent conveying with regular stops under the drive of the roller. The operator can adjust the intermittent rotation step of the indexing wheel 4 by adjusting the speed of the motor 2 to control the stopping frequency and progress of the conveyor belt 11. The surface of the conveyor belt 11 has multiple sets of strip grooves of different widths distributed in a gradient along the length direction, which can be embedded and positioned according to the nickel sheet weaving size to provide a precise position for nickel sheet placement.When the indexing transmission assembly drives the conveying assembly, the feeding execution assembly starts synchronously. The feeding mechanism mounting plate 12 is sleeved on the top of the adjacent conveyor belt side support column 8 through the elongated hole on its surface, and is fixed by locking bolts.
