Description

Technical Field

[0001] This utility model relates to the field of automated feeding equipment technology, and in particular to an automated feeding mechanism for magnetizing dual-track code disks. Background Technology

[0002] Dual-track code disks, as the core component of high-precision encoders, consist of a main track and a vernier track. They require a magnetization process to impart precise magnetic signal characteristics and are widely used in industrial automation, robotics, precision instruments, and other fields. During the magnetization process, the technical level of the feeding stage directly determines the magnetization accuracy, production efficiency, and product yield. Core requirements include achieving stable gripping and precise positioning of the code disk, adapting to different code disk specifications, avoiding magnetic signal distortion caused by scratches on the magnetic track surface or positioning deviations, and meeting the automation needs of large-scale production.

[0003] Currently, the feeding technology for magnetizing dual-track code disks still has many shortcomings that urgently need to be addressed: manual feeding is inefficient, has large positioning errors, easily damages the code disk, and has high labor costs and a high defect rate; single-set fixed-gap suction cup mechanisms can only adapt to a single specification of code disk, have long changeover times, insufficient positioning stability, and cannot meet the special positioning requirements of dual-track structures; single-set adjustable-gap suction cup mechanisms, although having a certain degree of compatibility, have limited support points, which easily leads to deformation of thin code disks, and the positioning accuracy is difficult to meet the requirements of magnetization air gap, and lacks dual-track collaborative positioning logic; mechanical clamping mechanisms are difficult to control the clamping force, which easily causes deformation of the code disk edge or damage to the magnetic track, and has high changeover costs; general-purpose vibratory feeder feeding mechanisms have problems such as code track wear, narrow compatibility specifications, and frequent jamming.

[0004] The technical problem this application aims to solve is: to address the existing problems of poor adaptability, insufficient positioning accuracy, easy damage to workpieces, and low automation and production efficiency of dual-track encoder magnetic feeding mechanisms. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic feeding mechanism for magnetizing dual-track code disks that is adaptable to multiple specifications, has accurate positioning, and stable gripping.

[0006] The technical solution adopted by this utility model is as follows: an automatic feeding mechanism for magnetizing dual-track code disks, including a material tray, a feeding frame on the top of the material tray, a moving mechanism on the feeding frame, the moving mechanism including guide rods and worm gears mounted on both sides of the feeding frame and a moving disk that moves back and forth along the guide rods and worm gears, a lifting gripping mechanism at the bottom of the moving disk, the gripping mechanism including a gripping plate that moves synchronously with the moving disk, the gripping plate having at least two sets of suction cups, each set of suction cups including at least two suction cups, a fixed sleeve on the top of each suction cup, a screw thread screwed into the fixed sleeve, the screw thread rotating within the fixed sleeve to drive two sliding plates to move closer or further apart.

[0007] The drive motor, through the transmission of the active and driven gears in the gearbox, drives the worm gear and worm to mesh and rotate, causing the moving disk to move precisely left and right along the guide rod. At the same time, the telescopic cylinder drives the lifting frame to lift the gripping plate. By turning the lead screw, the screw connection between the lead screw and the fixed sleeve drives the sliding plate to move along the sliding groove of the gripping plate, realizing the adjustment of the distance between the two suction cups in each suction cup group, adapting to dual-track code disks of different diameters. The two suction cup groups work together to form a four-point support structure. The vacuum pump is connected to the suction cup through the fixed part to generate negative pressure, completing the stable gripping of the code disk. After gripping, the code disk is transported to the magnetization station by the cooperation of the moving mechanism and the lifting mechanism. When deflating, the negative pressure is released to achieve precise unloading.

[0008] In some embodiments, the top of the suction cup is provided with a sliding plate that slides along the top of the gripping plate. The gripping plate has a sliding groove that is matched with the bottom of the sliding plate. When the lead screw rotates to drive the sliding plate, the bottom of the sliding plate is embedded in the sliding groove and slides directionally along the groove. The movement trajectory of the sliding plate is constrained by the limiting effect of the sliding groove. The limiting match between the sliding groove and the sliding plate avoids offset or shaking during suction cup adjustment, ensures the adjustment accuracy of the distance between the two suction cups in each suction cup group, and thus ensures the center positioning accuracy when the code disk is gripped, and improves the uniformity of magnetic track magnetization during magnetization.

[0009] In some embodiments, the moving mechanism also includes a worm wheel that cooperates with the worm drive. A gearbox is provided on one side of the worm wheel to drive its rotation, and a drive motor is mounted on the top of the moving disk outside the gearbox. After the drive motor starts, it outputs power, which is transmitted to the worm wheel through the gearbox. The worm wheel meshes with the worm, converting the rotational motion into the linear reciprocating motion of the moving disk along the guide rod. The worm wheel and worm gear transmission has the characteristics of stable transmission ratio and good self-locking performance, which can effectively prevent the moving disk from being accidentally displaced during the gripping and conveying process, and improve the stability of the mechanism operation. At the same time, the drive motor and gearbox are integrated and mounted on the top of the moving disk, which optimizes the structural layout and reduces the space occupation.

[0010] In some embodiments, the gearbox contains a driving gear and a driven gear that mesh with each other. The driving gear is installed at the output end of the drive motor, and the driven gear is fixedly installed with the worm gear. The drive motor drives the driving gear to rotate, and the meshing of the driving gear and the driven gear realizes power transmission, which in turn drives the worm gear to rotate synchronously, driving the moving disk to move. The gear meshing transmission has high efficiency and precise power transmission, which can realize the high-speed and stable movement of the moving disk, ensuring the consistency of the feeding rhythm of the code disk. At the same time, the gearbox protects and lubricates the gear set, extends the service life of the transmission components, and reduces maintenance costs.

[0011] In some embodiments, a vacuum pump is mounted on the top of the suction cup and installed on the top of the sliding plate. A fixing component is fixed to the top of the vacuum pump, and a fixing sleeve is fixedly installed with the fixing component. The vacuum pump is fixed to the fixing sleeve through the fixing component to ensure a sealed air passage with the suction cup. During operation, the vacuum pump draws air to create a negative pressure in the inner cavity of the suction cup, adsorbing the code disk. When deflating, the pressure is quickly balanced and the code disk is released. The close integration of the vacuum pump and the suction cup reduces the length of the air passage, reduces negative pressure loss, improves the adsorption response speed and negative pressure stability, and prevents the code disk from being poorly adsorbed or falling off. The firm connection between the fixing component and the fixing sleeve ensures the relative position stability of the vacuum pump and the suction cup during the gripping process, further improving the adsorption reliability.

[0012] In some embodiments, a screw-operated part is fixedly installed at the end of the lead screw; the operator can manually or with the aid of tools rotate the screw-operated part to drive the lead screw to rotate within the fixed sleeve, thereby driving the sliding plate to move and adjust the suction cup spacing; the design of the screw-operated part simplifies the adjustment operation of the suction cup spacing, and the adjustment can be completed quickly without complicated tools, improving the efficiency of changing different specifications of encoders, reducing the labor intensity of operators, and at the same time, the screw-operated part can increase the gripping force, making it easier to accurately control the adjustment range and improve the spacing adjustment accuracy.

[0013] In some implementations, a lifting frame is fixed to the top of the gripping plate, and a telescopic cylinder is installed on the top of the lifting frame. A side plate is fixed to one side of the telescopic cylinder, and the side plate is fixed to the bottom of the moving disk. The telescopic cylinder is fixed to the bottom of the moving disk through the side plate. The piston rod of the telescopic cylinder extends and retracts, driving the lifting frame to move up and down, thereby driving the gripping plate and the suction cup assembly to rise and fall synchronously, realizing the contact adsorption and separation unloading of the suction cup and the code disk. The use of a telescopic cylinder to drive the lifting has the characteristics of fast response speed and precise stroke control. It can effectively control the contact force between the suction cup and the code disk, avoiding damage to the code disk magnetic track due to excessive contact pressure. At the same time, the lifting stroke can be flexibly adjusted according to the thickness of the code disk and the height of the magnetization station, adapting to different production scenarios. The structure is simple and reliable, and the maintenance cost is low.

[0014] The beneficial effects of this utility model are as follows: the screw-connected adjustment structure of the lead screw and the fixed sleeve enables flexible adjustment of the suction cup spacing, adapting to the full range of dual-track code disk specifications, eliminating the need to change fixtures, and significantly shortening changeover time. The four-point support design of the two sets of suction cups improves the stability of code disk gripping, avoids deformation or tilting of thin code disks, and ensures precise control of the magnetization air gap. At the same time, the worm gear transmission and guide rod guidance of the moving mechanism improve the moving positioning accuracy. Combined with the negative pressure adsorption of the vacuum pump, damage to the code disk magnetic track is avoided, significantly improving the magnetization yield and production efficiency.

[0028] Working principle and usage process of this utility model:

Utilizing the screw connection between the lead screw 35 and the fixed sleeve 36, as well as the limiting and guiding effect of the sliding plate 321 and the sliding groove 322, the two suction cups 34 in each suction cup group are driven to adjust the spacing synchronously until they are compatible with the non-magnetic track adsorption area of ​​the code disk.

[0030] Then the drive motor 24 starts, and the worm gear 26 is driven to rotate through the meshing of the drive gear 251 and the driven gear 252. The worm gear 26 meshes with the worm 23 to drive the moving disk 21 to move along the guide rod 22 directly above the material disk 1. After it reaches the position, the piston rod of the telescopic cylinder 5 extends, driving the lifting frame 31 and the gripping plate 32 to move down, so that the suction cup 34 is attached to the upper surface of the code disk.

[0031] Vacuum pump 33 starts to pump air, so that a stable negative pressure is formed between suction cup 34 and code disk. After the negative pressure reaches the standard, telescopic cylinder 5 retracts to lift code disk to a safe height, drive motor 24 to rotate in reverse, and transport code disk to magnetization station through moving mechanism 2.

[0032] Finally, the moving plate 21 stops moving, the telescopic cylinder 5 lowers the code plate to the preset air gap of the magnetizing head, the vacuum pump 33 connects to the atmosphere to release negative pressure, and after the code plate is placed stably, all components reset and enter the next cycle.
