Linear track with adjustable increased sliding resistance

Abstract

The present invention discloses a linear track with adjustable increased sliding resistance. A metal plate is fixedly connected to the side surface of a slider sliding on the linear track, and a magnetic adjustable mechanism is arranged outside the plate. The magnetic adjustable mechanism is composed of a magnet and a gap adjustable mechanism. The gap adjustable mechanism is composed of a backrest, a sliding rod, and a sliding connection bracket. The magnet is closely attached to the inner side of the backrest. One end of the sliding rod is fixedly connected to the outside of the backrest, and the other end of the sliding rod passes through a sliding hole on the sliding connection bracket and can move through it, so that the magnet backrest and the sliding rod move synchronously, thereby adjusting the gap between the magnet and the metal plate, and further changing the magnetic force. The present invention increases the sliding resistance of the linear track, reduces the sliding distance, and the sliding or vibration amplitude is easy to design and control.

Description

Technical Field

[0001] The invention relates to a technology for adjusting the resistance of a slide rail. Background Art

[0002] The tracks used by trains on urban rails or the tracks used to transport components in the semiconductor industry sometimes need to reduce the sliding distance on the tracks, such as by braking, but the noise from braking is loud and the mechanical wear is serious. Alternatively, the sliding friction coefficient can be increased to increase the sliding resistance and reduce the sliding distance, but this is not conducive to normal sliding. Alternatively, the dragging method in the opposite direction can be used to reduce the sliding distance, but this requires additional energy consumption.

[0003] The invention with application publication number: CN117927844A discloses a lubrication device for a linear guide slider and a method of using the same, which relates to the technical field of guide slider lubrication, and includes: a slider body, a guide rail body and a lubrication assembly, wherein the outer wall of the guide rail body is slidably connected to the slider body, the front and back of the slider body are both equipped with lubrication assemblies, a lubrication state detection module is installed on the front of the lubrication assembly, the lubrication state detection module includes an acceleration sensor and a control module, and a warning module is provided on the front of the lubrication assembly. The purpose of the invention is to reduce sliding resistance, and there is no description of the reverse process of increasing resistance and reducing sliding distance. Summary of the invention

[0004] Purpose of the invention: In order to overcome the problems of long sliding distance of materials on traditional slide rails, severe wear and heat caused by sudden braking, a configurable magnet is provided, which utilizes the principle of like-pole repulsion and opposite-pole attraction or the principle of eddy current to increase the sliding resistance of the slide rail and reduce the sliding distance to form an adjustable linear track with increased sliding resistance.

[0005] Technical solution: The linear track with adjustable sliding resistance of the present application has a metal plate (an alloy of iron, cobalt or nickel, or a copper alloy plate) fixedly connected to the side (one or both sides parallel to the sliding direction) of the sliding component of the linear track (such as a slider, or a pulley, or a mover of a linear motor, which is usually made of non-metallic material). The length of the metal plate can be the same as or slightly shorter than the length of the slider; a magnetic adjustable mechanism is provided on the outer side of the plate (the side away from the sliding component).

[0006] The magnetic adjustable mechanism is composed of a magnet (permanent magnet or electromagnet) and a gap adjustable mechanism. The gap adjustable mechanism is composed of a backing (non-metallic material, which does not affect the magnetic and electrical properties), a sliding rod (including a screw), and a sliding bracket (a sliding groove that matches the gap of the sliding rod and a clamping pin perpendicular to the sliding rod are provided in the bracket to control the left and right movement of the sliding rod; or a screw-connected bracket, in which a hole is provided in the bracket for the screw to pass through, and a nut is screwed on each of the screws on both sides of the hole to control the left and right movement of the screw). The magnet is tightly attached to the inner side of the backrest (the side close to the above-mentioned metal plate), one end of the slide rod is fixedly connected (or rotatably connected) to the outer side of the backrest, and the other end of the slide rod passes through the sliding hole (or screw hole) on the sliding bracket and can pass through (or rotate) therein, so that the backrest and the slide rod (or screw) move synchronously, and the magnet can follow the movement, thereby adjusting the gap distance between the magnet and the above-mentioned metal plate; and then adjusting the magnetic force of the magnet on the metal plate (such as magnetic attraction), so that the magnetic force of the magnet on the metal plate on the sliding component forms a corresponding relationship with the gap (GAP), and the size of the magnetic force is adjusted by adjusting the gap, thereby reducing the vibration amplitude and frequency of the slider.

[0007] Preferably, there is an identical metal plate on each of the left and right sides, which is an alloy of iron, cobalt or nickel; left and right magnets (the magnetic poles are symmetrically arranged and symmetrically adsorbed) or different magnetic poles (N pole or S pole) of the magnet are respectively arranged at the adjustable gap on the outer side of the left and right metal plates, so that the magnets on both sides respectively generate attraction to the metal plates on their respective sides (any magnetic pole can generate attraction to the alloy of iron, cobalt or nickel), thereby dragging the sliding of the magnet and the slider, thereby reducing the sliding distance or vibration amplitude of the slider, and reducing the number of sliding or vibration times.

[0008] Alternatively, it is preferred that the left and right metal plates are the same copper alloy plates, and the left and right magnets are different magnetic poles (N pole and S pole), that is, the outer sides of the copper alloy plates on both sides of the slider have N poles and S poles separated by adjustable gaps. With this structure, when the slider moves back and forth on the track, the copper alloy plates cut the magnetic lines of force of the magnets with different magnetic poles, thereby generating magnetic eddy currents, thereby significantly reducing the vibration amplitude of the slider and reducing the number of vibrations even more.

[0009] The application scope and beneficial effects of the present invention are as follows: The present invention is particularly suitable for use in track motion mechanisms of semiconductor manufacturing equipment.

[0010] Technical effect: The present invention increases the sliding resistance of the linear track, reduces the sliding distance, or reduces the vibration amplitude; and through the parameter involvement of the magnet and the metal plate, such sliding or vibration becomes easy to control.

[0011] Furthermore, the present invention utilizes the interaction of magnetic materials, the magnet and the metal plate are non-contact, no dirt will be generated, no frictional heat will be generated, and there is almost no adverse effect on the quality of the microelectronic components.

[0012] By cutting the magnetic lines of force in the magnetic field of different magnetic poles, the sliding or vibration amplitude of the slider placed in the magnetic field will be smaller, the sliding distance will be shorter or the vibration amplitude will be smaller.
