Description

Technical Field

[0001] This utility model provides a loading and unloading device for assembling magnetic pillars and magnetic sheets, belonging to the field of magnetic sheet assembly technology, and particularly relates to an assembly table that facilitates the assembly of magnetic sheets by workers. Background Technology

[0002] In the manufacturing process of magnetic encoders, the assembly of the magnetic rotor is one of the core steps determining the product's performance and accuracy. The magnetic rotor typically consists of magnetic sheets and matching plastic or metal bushings. Its function is to provide a stable and accurately identifiable magnetic field signal for the encoder system, and the assembly precision of this component is crucial. Currently, in many production scenarios, especially in flexible production with small batches and diverse product varieties, this precise assembly operation still heavily relies on skilled workers performing manual operations; workers install the magnetic sheets into the rotor on an assembly table.

[0003] The existing manual assembly method exposes two particularly prominent technical challenges. First, in the loading stage, due to the extremely strong magnetism of the neodymium iron boron and other permanent magnet materials used in the rotor, when a large number of magnetic sheets are stored in the hopper, they will attract each other due to magnetic force. This makes removal inconvenient and severely impacts loading efficiency. Second, the unloading and conveying stages present equally serious problems. Even after the magnetic sheets have been successfully assembled into the bushings to form complete rotor parts, their exposed magnetism remains. When these assembled rotors are placed on the tray or conveyor belt, they will attract and collide with each other due to magnetic force, resulting in disordered arrangement of parts; this creates significant difficulties for subsequent collection, inspection, and packaging processes. Therefore, there is an urgent need to develop an assembly platform that facilitates loading and unloading to fundamentally solve the series of problems caused by magnetic attraction during the loading and unloading process. Utility Model Content

[0004] The technical problem this invention aims to solve is that during the assembly of magnetic sheets, the magnetic sheets in the hopper attract each other and are difficult to separate, and the magnetic attraction also causes the parts to become disordered during unloading.

[0005] To solve the above problems, the proposed technical solution is as follows: a loading and unloading device for assembling magnetic pillars and magnetic sheets, comprising an assembly table and a storage cylinder; the storage cylinder is horizontally fixedly mounted on the assembly table, and the magnetic sheets are sequentially adsorbed and arranged inside the storage cylinder; a groove is provided on one side of the assembly table, and a fixing plate is fixedly mounted in the groove; further comprising:

[0006] A rotating plate and a conveyor belt; the rotating plate is rotatably mounted above the fixed plate, and the rotating plate has several placement holes for placing assembled parts, each placement hole being independently separated; the conveyor belt is mounted below the fixed plate, and the fixed plate has a feeding hole that can communicate with the placement holes, and the feeding hole corresponds to the conveyor belt;

[0007] The material pusher assembly and the feeding plate are included. The material pusher assembly, which can push the mutually attracted magnetic sheets out of the storage cylinder, is slidably disposed inside the storage cylinder. An L-shaped bracket is fixedly connected to the storage cylinder, and the feeding plate, which can push the magnetic sheets exposed from the storage cylinder onto the assembly table, is slidably disposed inside the L-shaped bracket. A fixed cylinder is fixedly disposed on the L-shaped bracket, and an elastic telescopic assembly that can drive the feeding plate to slide is disposed inside the fixed cylinder.

[0008] Preferably, the placement hole is a through hole that penetrates the rotating plate from top to bottom, and the placement holes are distributed circumferentially on the rotating plate; the feeding hole is located on the rotation path of all the placement holes.

[0009] Preferably, the bottom of the fixing plate is fixedly connected to a guide plate corresponding to the feeding hole, and the lower end of the guide plate corresponds to the conveyor belt.

[0010] Preferably, a support frame is fixedly installed on the ground below the fixed plate; a rotating motor is installed inside the support frame, and a rotating shaft is fixedly connected to the output end of the rotating motor, and the rotating shaft passes through the fixed plate and is fixedly connected to the rotating plate.

[0011] Preferably, the pushing assembly includes a pushing plate and a pushing operation rod; the pushing plate is slidably disposed inside the storage cylinder, and a guide groove communicating with the storage cylinder is opened on the outer wall of the storage cylinder, and the pushing operation rod located in the guide groove is fixedly connected to the pushing plate.

[0012] Preferably, the elastic telescopic component includes a sliding plate, a spring, and a connecting rod; the sliding plate is slidably disposed inside the fixed cylinder, and the connecting rod fixedly connected below the sliding plate is fixedly connected to the feeding plate; the spring located inside the fixed cylinder is sleeved on the connecting rod; the outer wall of the fixed cylinder has a connecting groove communicating with the fixed cylinder, and the feeding operation rod located in the connecting groove is fixedly connected to the sliding plate.

[0013] Preferably, the feeding plate is arc-shaped, and the assembly table is provided with a limiting groove corresponding to the feeding plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. This device, through the cooperation of a horizontally positioned storage cylinder and a pushing assembly, effectively solves the core problem of magnetic sheets being attracted to each other by magnetic force and difficult to retrieve within the hopper. The pushing plate can push out the magnetic sheets one by one, and together with the feeding plate, it can precisely push them onto the assembly table, realizing rapid feeding of individual magnetic sheets and greatly improving feeding efficiency and reliability.

[0016] 2. In the unloading stage, a rotating plate with independently separated placement holes ensures that each assembled rotor part is physically isolated during transport, fundamentally eliminating magnetic attraction and collisions between parts. When the rotating plate circulates to the unloading hole, the parts fall orderly onto the conveyor belt, achieving rapid and neat separation and transport of assembled parts. This lays a solid foundation for the automated connection of subsequent processes and significantly improves the overall efficiency of the production line and the level of product protection.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] This utility model provides a loading and unloading device for assembling magnetic columns and magnetic sheets: including an assembly table 1 and a storage cylinder 8; the storage cylinder 8 is horizontally fixed on the assembly table 1, and the magnetic sheets 23 are sequentially adsorbed and arranged in the storage cylinder 8; a groove 2 is provided on one side of the assembly table 1, and a fixing plate 7 is fixedly installed in the groove 2.

[0024] Reference Appendix Figure 1 , 2 The rotating plate 3 is rotatably mounted above the fixed plate 7. The rotating plate 3 has several placement holes 4 for placing assembled parts. Each placement hole 4 is independently separated to ensure that the assembled rotor parts do not attract each other. A support frame 10 is fixedly mounted on the ground below the fixed plate 7. A rotating motor 12 is installed inside the support frame 10. A rotating shaft 11 is fixedly connected to the output end of the rotating motor 12, and the rotating shaft 11 passes through the fixed plate 7 and is fixedly connected to the rotating plate 3.

[0025] The conveyor belt 6 is located below the fixed plate 7. The fixed plate 7 has a discharge hole 13 that can communicate with the placement hole 4, and the discharge hole 13 corresponds to the conveyor belt 6. The placement holes 4 are arranged circumferentially on the rotating plate 3, and the discharge hole 13 is located on the rotation path of all the placement holes 4. When the rotating motor 12 drives the rotating plate 3 to rotate, the placement holes 4 correspond to the discharge holes 13 in sequence. The placement holes 4 are through holes that penetrate the rotating plate 3 from top to bottom. At this time, the parts located in the placement holes 4 fall directly through the discharge holes 13.

[0026] A guide plate 5 corresponding to the discharge hole 13 is fixedly connected to the bottom of the fixed plate 7, and the lower end of the guide plate 5 corresponds to the conveyor belt 6. The parts falling from the discharge hole 13 enter the conveyor belt 6 through the guide plate 5, thereby transporting the finished parts.

[0027] Reference Appendix Figure 3 , 4 A pusher assembly capable of pushing mutually attracted magnetic sheets 23 out of the storage cylinder 8 is slidably disposed within the storage cylinder 8. The pusher assembly includes a pusher plate 24 and a pusher operating rod 25. The pusher plate 24 is slidably disposed within the storage cylinder 8, and a guide groove 14 communicating with the storage cylinder 8 is opened on the outer wall of the storage cylinder 8. The pusher operating rod 25, located within the guide groove 14, is fixedly connected to the pusher plate 24. The operator holds the pusher operating rod 25 to drive the pusher plate 24 to slide, thereby pushing the magnetic sheets 23 sequentially to the opening of the storage cylinder 8.

[0028] An L-shaped bracket 15 is fixedly connected to the storage cylinder 8, and the loading plate 16, which can push the magnetic sheet 23 exposed from the storage cylinder 8 onto the assembly table 1, is slidably disposed in the L-shaped bracket 15; a fixed cylinder 17 is fixedly disposed on the L-shaped bracket 15, and an elastic telescopic component that can drive the loading plate 16 to slide is disposed inside the fixed cylinder 17.

[0029] The elastic telescopic assembly includes a sliding plate 20, a spring 21, and a connecting rod 22. The sliding plate 20 is slidably disposed within a fixed cylinder 17, and the connecting rod 22, fixedly connected below the sliding plate 20, is fixedly connected to the feeding plate 16. The spring 21, located within the fixed cylinder 17, is sleeved on the connecting rod 22. A connecting groove 18 communicating with the fixed cylinder 17 is provided on the outer wall of the fixed cylinder 17, and a feeding operation rod 19 located within the connecting groove 18 is fixedly connected to the sliding plate 20. The spring 21 serves a reset function. When the operator presses down on the feeding operation rod 19, it pushes the feeding plate 16 downward while compressing the spring 21. Once the feeding operation rod 19 is released, the feeding plate 16 automatically resets under the restoring force of the spring 21, awaiting the next feeding action. The feeding plate 16 is arc-shaped, which can cooperate with the cylindrical magnetic sheet 23. The assembly table 1 has a limiting groove 9 corresponding to the feeding plate 16. The magnetic sheet 23 that is pushed down falls directly into the limiting groove 9, preventing it from rolling on the assembly table 1 when it falls. It should be noted that in this application, all components that come into contact with the magnetic sheet 23, such as the storage cylinder 8, the feeding plate 16, the assembly table 1, the rotating plate 3, the fixing plate 7, and the guide plate 5, are made of non-ferromagnetic materials, such as austenitic stainless steel.

[0030] The operator first places a batch of magnetic sheets 23 into the horizontally positioned storage cylinder 8. The magnetic sheets 23 will be attracted and arranged sequentially due to magnetism. When feeding the magnetic sheets 23, refer to the attached... Figure 3 , 4 By pushing the pusher lever 25, the pusher plate 24 slides within the storage cylinder 8, smoothly pushing the foremost magnetic sheet 23 out of the cylinder opening. Then, the operator presses the loading lever 19, driving the sliding plate 20 within the fixed cylinder 17 to move downwards. The sliding plate 20 compresses the spring 21, which, through the connecting rod 22, drives the arc-shaped loading plate 16 to slide along the L-shaped bracket 15, precisely pushing the single magnetic sheet 23 that has been pushed out of the cylinder opening into the limiting groove 9 on the assembly table 1. This completes the rapid, single-piece loading of the magnetic sheet 23, effectively preventing mutual adsorption between the magnetic sheets 23. After loading a single magnetic sheet 23, the loading lever 19 is released, and under the restoring force of the spring 21, the loading plate 16 automatically resets, awaiting the next loading action.

[0031] After the magnetic sheet 23 is assembled with the substrate on assembly table 1, the finished rotor parts are placed into the independent placement holes 4 on the rotating plate 3, thereby separating the rotor parts and preventing them from adhering to each other. (See attached diagram) Figure 1 , 2The rotating motor 12 is started, causing the rotating plate 3 to rotate intermittently. When the placement hole 4 carrying the part rotates to align with the discharge hole 13 on the fixed plate 7, the part falls through the discharge hole 13 under the action of gravity and is guided smoothly by the guide plate 5 onto the conveyor belt 6 below. Each placement hole 4 on the rotating plate 3 is independently separated, ensuring that the parts remain isolated during the conveying process. This fundamentally prevents the finished products from being disordered or damaged due to magnetic attraction and collision, achieving orderly and efficient material discharge and conveying.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
