Description

Technical Field

[0001] This utility model relates to the field of linear motor technology, and in particular to a beam-type high-precision magnetic linear motor module. Background Technology

[0002] Against the backdrop of modern manufacturing's transformation towards high precision and high efficiency, linear motor modules, as core components for achieving precise linear motion, are widely used in high-end fields such as semiconductor manufacturing, precision machining, and optical inspection. However, traditional linear motor modules face numerous challenges in practical applications. For example, single-rail or low-precision rail designs struggle to maintain stability under high-speed operation and heavy loads, easily exhibiting vibration and misalignment, leading to decreased motion accuracy. Furthermore, the lack of effective external protection devices makes internal components susceptible to contamination from dust, debris, and liquids, thus affecting service life and operational reliability.

[0003] The inventors believe that the following defects often exist: under complex working conditions of high speed and heavy load, the operation of the linear motor body is unstable, which reduces the product defect rate caused by unstable motion, increases the equipment burden and the cost of use; therefore, a beam-type high-precision magnetic linear motor module is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as unstable operation of the linear motor body under complex working conditions of high speed and heavy load, which reduces the product defect rate caused by unstable motion, increases the equipment burden and operating costs. Therefore, a beam-type high-precision magnetic linear motor module is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a beam-type high-precision magnetic linear motor module, comprising an integrated aluminum beam, a first guide rail fixedly connected to the upper surface of the integrated aluminum beam, a second guide rail fixedly connected to one side of the integrated aluminum beam, two sliders slidably connected to the surface of the first guide rail, two sliders slidably connected to the surface of the second guide rail, slide blocks fixedly connected to the surfaces of the four sliders, and a linear motor body fixedly connected to the surface of the integrated aluminum beam.

[0006] The effects achieved by the above components are as follows: through the dual-rail and multi-slider structure design of the first and second guide rails, the operational stability is greatly enhanced, avoiding the instability of the linear motor body under complex working conditions of high speed and heavy load, thereby reducing the product defect rate caused by unstable motion, reducing the burden on equipment and operating costs, and improving the production quality of the equipment.

[0007] Preferably, a grating ruler is fixedly connected to the inner surface of the slide, and two proximity switches are fixedly connected to the surface of the integrated aluminum crossbeam.

[0008] The effect achieved by the above components is that the linear motor body and the positioning system of the grating ruler work together to achieve high-precision positioning under high-speed motion, which can be widely used in fields with extremely high precision requirements such as semiconductor manufacturing, precision machining, and optical inspection, thus expanding the application range of the linear motor body.

[0009] Preferably, the integrated aluminum crossbeam is made of aluminum alloy, and three slots are provided on both sides of the integrated aluminum crossbeam.

[0010] The effect achieved by the above components is that the crossbeam made of high-strength lightweight aluminum alloy serves as the main frame, providing stable support for the entire linear motor body, and effectively reducing the overall weight and operating load.

[0011] Preferably, a first bellows cover is fixedly connected to the surface of the integrated aluminum beam, and a second bellows cover is fixedly connected to the surface of the integrated aluminum beam.

[0012] The effects achieved by the above components are: effective protection of the first and second bellows covers, reducing the corrosion of the internal components of the equipment by the external environment, reducing maintenance costs, improving the reliability and continuous operation time of the equipment, and reducing production downtime.

[0014] The effect achieved by the above components is to further reduce the corrosion of the internal components of the equipment by the external environment.

[0018] Reference Figure 1-5 As shown, this utility model provides a technical solution: a beam-type high-precision magnetic linear motor module, including an integrated aluminum beam 1. A first guide rail 2 is fixedly connected to the upper surface of the integrated aluminum beam 1, and a second guide rail 3 is fixedly connected to one side of the integrated aluminum beam 1. Two sliders 5 are slidably connected to the surface of the first guide rail 2, and two sliders 5 are slidably connected to the surface of the second guide rail 3. A slide block 4 is fixedly connected to the surface of the four sliders 5. A linear motor body 6 is fixedly connected to the surface of the integrated aluminum beam 1. Through the structural design of the double guide rails 2 and 2 guide rails 3 and multiple sliders 5, the operational stability is greatly enhanced, avoiding the instability of the linear motor body 6 under complex working conditions of high speed and heavy load, thereby reducing the product defect rate caused by unstable movement, the increased equipment burden and operating costs, and improving the production quality of the equipment. A grating ruler 7 is fixedly connected to the inner surface of the slide block 4, and two proximity switches 10 are fixedly connected to the surface of the integrated aluminum beam 1. The linear motor body 6 and the grating ruler 7 are fixedly connected to the linear motor body 6. With the cooperation of the positioning system, high-precision positioning under high-speed motion is achieved, which can be widely used in fields with extremely high precision requirements such as semiconductor manufacturing, precision machining, and optical inspection, expanding the application range of the linear motor body 6. The integrated aluminum crossbeam 1 is made of aluminum alloy, and three slots are opened on both sides of the integrated aluminum crossbeam 1. The crossbeam, made of high-strength lightweight aluminum alloy, serves as the main frame, providing stable support for the entire linear motor body 6 and effectively reducing the overall weight and operating load. The surface of the integrated aluminum crossbeam 1 is fixedly connected to the first bellows cover 8 and the second bellows cover 9. The effective protection of the first bellows cover 8 and the second bellows cover 9 reduces the corrosion of the internal components of the equipment by the external environment, reduces maintenance costs, improves the reliability and continuous operation time of the equipment, and reduces production downtime. The two sides of the integrated aluminum crossbeam 1 are fixedly connected to the side guard plates 11, and both side guard plates 11 are fixedly connected to the second guide rail 3, further reducing the corrosion of the internal components of the equipment by the external environment.

[0019] Working principle and component manufacturing: The integrated aluminum crossbeam 1 is precision machined according to strict design dimensions and precision requirements to ensure its form and position tolerances and surface roughness meet standards. The first guide rail 2 and the second guide rail 3 are manufactured using professional precision machining equipment and undergo fine grinding and heat treatment to improve hardness and wear resistance. The stator and mover of the linear motor body 6 are precisely assembled according to the magnetic circuit design, and the grating ruler 7 is made using a high-precision etching process. The first bellows cover 8 and the second bellows cover 9 are customized according to the module's movement range and dimensions to ensure both tight protection and flexibility.

[0020] Module Assembly: First, install the high-precision first guide rail 2 and second guide rail 3 parallel to each other on the crossbeam. Use high-precision measuring instruments and adjustment tools to ensure that the parallelism and straightness of the first guide rail 2 and second guide rail 3 are within the specified range. Next, install the stator of the linear motor body 6 and assemble the mover with the load connection mechanism. Then, install the grating ruler 7 and reading head, ensuring that the gap between them is uniform and meets the accuracy requirements. Finally, install the first bellows cover 8 and the second bellows cover 9, allowing them to extend and retract freely and fit tightly with the module components.

[0021] Debugging and Testing: After assembly, the module undergoes electrical connection and system debugging. Performance testing of the linear motor body 6 is performed, including measurement of parameters such as speed, acceleration, and thrust; simultaneously, the grating positioning system is calibrated and its accuracy verified. Load testing and long-term operation testing are conducted to simulate the actual working environment. Based on the test results, necessary adjustments and optimizations are made to the module to ensure that its performance indicators meet design requirements.

[0022] Meanwhile, the working principle of the linear motor body 6 is based on the law of electromagnetic induction. It mainly consists of a stator and a mover. The stator has uniformly distributed permanent magnets, forming a constant magnetic field. The mover contains the armature winding. When an external power source supplies three-phase alternating current to the armature winding, a rotating magnetic field that changes with time is generated around the winding. According to the principle of electromagnetic induction, this rotating magnetic field interacts with the magnetic field of the permanent magnets in the stator, generating an electromagnetic force. Since the linear motor body 6 is a device that converts the rotating magnetic field into linear motion, under the action of this electromagnetic force, the mover will reciprocate along a straight line, thus directly generating a linear driving force. This eliminates the need for the complex traditional transmission mechanism, giving the linear motor body 6 significant advantages over the traditional rotary motor with its transmission mechanism.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
