Description

Technical Field

[0001] This utility model relates to the field of linear motor technology, and in particular to a linear motor that operates smoothly. Background Technology

[0002] In today's era of rapid technological advancement, numerous fields such as intelligent manufacturing, high-end equipment manufacturing, and automated logistics are undergoing profound transformations. The pursuit of high precision, high speed, and high efficiency has become the main theme of industry development. Linear motors, as key devices that directly convert electrical energy into linear motion mechanical energy, are poised to play a crucial role. With semiconductor processing advancing towards nanometer-level precision, the extreme demands for accuracy in surgical procedures from precision medical instruments, and the desire for a smoother and more comfortable ride in high-speed rail transportation, linear motors, with their unique advantages, are expected to break through many limitations of traditional mechanical transmission and usher in a new chapter in power transmission.

[0003] Linear motors, based on the law of electromagnetic induction, typically consist of two main parts: a stator and a mover. The stator generally contains windings, and when alternating current is applied, it generates a traveling magnetic field according to electromagnetic principles, resembling invisible magnetic waves surging in space. The mover, as a movable component that interacts with the stator's magnetic field, contains a permanent magnet or induction winding. Under the influence of the stator's traveling magnetic field, it is strongly driven by electromagnetic force, thus moving forward along a predetermined linear trajectory, bypassing the intermediate conversion steps required by rotary motors.

[0004] In the prior art, the cogging effect of some iron-core linear motors is like setting up periodic checkpoints on the path of the mover, causing the electromagnetic force to fluctuate periodically. When the mover moves, it will produce small but not negligible vibrations. Therefore, a linear motor with smooth operation is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a linear motor that operates smoothly, aiming to improve the problem of shaking in some devices in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a linear motor with smooth operation, comprising a fixed frame, a stabilizing mechanism fixedly connected inside the fixed frame, a sliding strip I slidably connected outside the fixed frame, a sliding mechanism provided outside the sliding strip I, the stabilizing mechanism comprising a sliding bar, the bottom of the sliding bar slidably connected outside the sliding bar I, buffer components provided on both sides of the top of the sliding bar, a second sliding bar provided on both sides of the top of the sliding bar, a working block slidably connected outside the second sliding bar, and a connecting component for connection fixedly connected inside the working block;

[0007] As a further description of the above technical solution: the sliding mechanism includes a side cover plate, the outside of which is fixedly connected to the inside of the fixed frame, a permanent magnet is fixedly connected to the top of the side cover plate, a main body is slidably connected to the outside of the side cover plate, a Hall sensor is fixedly connected to the inside of the main body, and a heat dissipation component is fixedly connected to the top of the Hall sensor.

[0008] As a further description of the above technical solution: the buffer assembly includes a buffer spring, the buffer spring is sleeved on the outside of the slide bar, and a buffer pressure is fixedly connected to the outside of the slide bar;

[0009] As a further description of the above technical solution: the driving end of the buffer pressure is fixedly connected to a buffer plate, the buffer spring is fixedly connected to the outside of the buffer plate, and the buffer plate is slidably connected to the outside of the slider.

[0010] As a further description of the above technical solution: the connecting component includes a locking tooth, the locking tooth is fixedly connected to the working block, a sliding block is fixedly connected to the outside of the locking tooth, and the sliding block is slidably connected to the outside of the slide bar;

[0011] As a further description of the above technical solution: a drag chain is fixedly connected to the bottom of the slide bar, and the other end of the drag chain is fixedly connected to the outside of the working block;

[0012] As a further description of the above technical solution: the heat dissipation component includes a heat dissipation layer, the bottom of which is fixedly connected to the top of the Hall sensor, and a heat collection layer is fixedly connected to the top of the heat dissipation layer.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when the working block slides on the slide bar and the second slide bar, the tight connection between the locking teeth and the sliding block enables the working block to move synchronously with the slide bar. When it moves to the edge, the buffer spring absorbs energy first due to its own elastic characteristics, and the buffer pressure further finely controls the buffering process, pushing the buffer plate to stabilize the working block. The dual buffering mechanism effectively suppresses the adverse effects of impact force, reduces shaking and vibration, and allows the motor to maintain stable operation whether it is in the starting, acceleration, constant speed or deceleration stage.

[0015] 2. In this utility model, it is inevitable that the Hall sensor will generate heat during continuous operation. The heat dissipation system composed of the heat dissipation layer and the heat collection layer operates efficiently, and the heat is transferred from the Hall sensor to the heat dissipation layer in an orderly manner. The heat dissipation layer evenly disperses the concentrated heat, reducing the risk of local overheating. Subsequently, the heat collection layer, with its large surface area, accelerates the dissipation of heat to the surrounding environment, reduces production interruptions caused by equipment maintenance, and improves production efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 4 and Figure 5 The present invention provides an embodiment of a linear motor that runs smoothly, including a fixed frame 1, a stabilizing mechanism fixedly connected inside the fixed frame 1, a sliding strip 2 slidably connected outside the fixed frame 1, and a sliding mechanism provided outside the sliding strip 2. The fixed frame 1 provides a stable frame for the entire motor, and its internal space is used to install the stabilizing mechanism.

[0025] The stabilizing mechanism includes a slide bar 9, the bottom of which is slidably connected to the outside of slide bar 2. Buffer components are provided on both sides of the top of slide bar 9 to buffer impact forces and reduce vibration during motor operation. Slide bars 13 are provided on both sides of the top of slide bar 9, providing a precise sliding track for the working block 7. The working block 7 is slidably connected to the outside of slide bar 13. The working block 7 is connected to slide bar 9 via a connecting component and slides on slide bar 9 under the guidance of slide bar 13. Slide bar 9 provides a basic path for the movement of the working block 7. A connecting component for connection is fixedly connected inside the working block 7. The buffer components include buffer springs. Spring 10, the buffer spring 10, due to its elastic properties, can be compressed when subjected to external force, converting the impact force into elastic potential energy and storing it. After the impact force disappears, the energy is released, playing a preliminary buffering and shock absorption role. The buffer spring 10 is sleeved on the outside of the slider 9. The buffer pressure 11 is fixedly connected to the outside of the slider 9. The driving end of the buffer pressure 11 is fixedly connected to the buffer plate 12. Under the drive of the buffer pressure 11, the buffer plate 12 transmits the buffering force to the working block 7, effectively reducing the impact of the impact force on the working block 7. The buffer spring 10 is fixedly connected to the outside of the buffer plate 12, and the buffer plate 12 is slidably connected to the outside of the slider 9.

[0026] The connecting assembly includes a locking tooth 8, which is externally fixedly connected to the working block 7. A sliding block 17 is externally fixedly connected to the locking tooth 8, and the sliding block 17 is externally slidably connected to the outside of the slide bar 9. A drag chain 6 is fixedly connected to the bottom of the slide bar 9. One end of the drag chain 6 is fixed to the bottom of the slide bar 9, and the other end is fixed to the outside of the working block 7. Its function is that during the sliding of the working block 7, the locking tooth 8 is fixed to the outside of the working block 7 and connected to the sliding block 17. Through the cooperative action with the sliding block 17, the working block 7 and the slide bar 9 are connected together, so that the working block 7 can slide stably on the slide bar 9. The sliding block 17 provides a support point for the working block 7 to slide on the slide bar 9. The other end of the drag chain 6 is fixedly connected to the outside of the working block 7.

[0027] Reference Figure 1 , Figure 2 and Figure 3The sliding mechanism includes a side cover plate 4, which is externally and fixedly connected to the inside of the fixed frame 1. A permanent magnet 3 is fixedly connected to the top of the side cover plate 4. The side cover plate 4 provides an installation and support structure for the permanent magnet 3 and the main body 5. The permanent magnet 3 is fixed to the top of the side cover plate 4 to provide a magnetic field for the motor. The main body 5 is slidably connected to the outside of the side cover plate 4. Under the action of the magnetic field generated by the permanent magnet 3, the main body 5 slides linearly along the side cover plate 4. A Hall sensor 14 is fixedly connected inside the main body 5. The Hall sensor 14 is fixed inside the main body 5 and its function is to detect the position change of the main body 5 relative to the permanent magnet 3 in real time and feed the position information back to the control. The system is designed to allow the control system to precisely control the movement speed and direction of the main body 5, ensuring the accuracy and stability of the motor operation. A heat dissipation component is fixedly connected to the top of the Hall sensor 14. The heat dissipation component includes a heat dissipation layer 16, the bottom of which is fixed to the top of the Hall sensor 14. Its function is to evenly distribute the heat generated by the Hall sensor 14. The heat collection layer 15 can quickly absorb the heat transferred from the heat dissipation layer 16 and dissipate the heat to the surrounding environment. It is a key part of the heat dissipation component and effectively ensures the normal operation of the Hall sensor 14. The bottom of the heat dissipation layer 16 is fixedly connected to the top of the Hall sensor 14, and the top of the heat dissipation layer 16 is fixedly connected to the heat collection layer 15.

[0028] Working principle: The fixed frame 1 provides a stable support foundation for the entire device. When it receives an external running command, the main body 5 begins to slide outside the side cover plate 4. The Hall sensor 14 installed inside the main body 5 senses the position change of itself relative to the permanent magnet 3 in real time. The working block 7 slides on the slider 9 and slider 13. The locking teeth 8 and the sliding block 17 ensure that the working block 7 and the slider 9 are tightly connected and move synchronously. The external drag chain 6 guides and controls the sliding stability of the working block 7. When sliding on both sides, it will be compressed by the buffer spring 10, absorbing some energy and reducing the impact force. At the same time, the drive end of the buffer pressure 11 pushes the buffer plate 12 to further buffer and stabilize the movement of the working block 7, preventing it from deviating from the predetermined trajectory or causing violent shaking due to external impact, and ensuring the smooth operation of the working block 7 and even the entire linear motor.

[0029] During operation, the Hall sensor 14 generates heat due to continuous operation. The heat is transferred from the Hall sensor 14 to the heat dissipation layer 16, which evenly distributes the heat and then transfers it to the heat collection layer 15. The heat collection layer 15 uses its large surface area to quickly dissipate the heat to the surrounding environment, preventing the Hall sensor 14 from being affected by overheating or even damaged, and ensuring the continuous and stable operation of the motor.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
