A linear motor positioning device

Abstract

This utility model provides a linear motor positioning device, relating to the field of linear motor technology, to solve the problems of existing linear motor positioning devices, which typically use anti-collision posts. These posts require replacement after prolonged use, and their cushioning and anti-collision effect deteriorates with use. The new device includes: slide rails fixedly mounted on both sides of the top of the main body; a magnetic rail positioned in the middle of the top of the main body; anti-collision posts on the main body; a coil inside the driving component; the driving component slidingly mounted on the slide rails; and magnetic posts on both sides of the driving component. When the driving component moves, if a magnetic post approaches an anti-collision post, the opposing surfaces of the anti-collision post and the magnetic post are made of the same pole. Due to the principle of like poles repelling each other, direct contact between the magnetic post and the anti-collision post is avoided, achieving an anti-collision effect. This replaces traditional anti-collision posts made of rubber or other materials, eliminates the need for periodic replacement, and provides greater stability during operation.

Description

Technical Field

[0001] This utility model belongs to the field of linear motor technology, and more specifically, relates to a linear motor positioning device. Background Technology

[0002] A linear motor positioning device is an electromechanical system that directly drives the load to perform linear motion through an electromagnetic field, and uses high-resolution position feedback to form a servo closed loop, achieving high-speed, high-acceleration, and high-precision position control under the action of complex control algorithms.

[0003] Based on existing technology, it has been found that existing linear motor positioning devices generally do not have protective devices during use. Over time, dust and other impurities inevitably accumulate on the surface, which is usually cleaned manually with compressed air. However, if impurities accumulate during production, the machine needs to be stopped for cleaning, which wastes time. In addition, existing linear motor positioning devices are usually equipped with anti-collision posts, which need to be replaced after long-term use. The buffering and anti-collision effect deteriorates with use, resulting in poor practicality. Utility Model Content

If impurities adhere during production, the machine must be stopped for cleaning, wasting time. Furthermore, existing linear motor positioning devices are usually equipped with anti-collision posts, which require replacement after prolonged use, and their cushioning and anti-collision effects deteriorate with use, resulting in poor practicality.

[0005] This utility model discloses a linear motor positioning device, which is achieved by the following specific technical means:

[0007] The installation mechanism is provided with a drive mechanism at the top; the rotation mechanism is provided on both sides of the drive mechanism; the cleaning mechanism is provided on the rotation mechanism and is located at the top of the installation mechanism.

[0009] The driving mechanism includes: a driving component, the driving component having a coil inside; the driving component being slidably mounted on a slide rail; and magnetic posts being provided on both sides of the driving component.

[0010] Furthermore, rectangular notches are provided on both sides of the main body; the slide rail is configured as an I-shaped structure; and the anti-collision post is made of magnetic material.

[0011] Furthermore, the driving component is a linear motor body; the magnetic column is made of magnet material; and the magnetic column and the anti-collision column have the same polarity on their opposite sides.

[0012] Furthermore, the rotating mechanism includes: a fixed component and a rotating component;

[0013] A motor is fixedly mounted on the fixing member; the fixing member is fixedly mounted on both sides of the top of the driving member; a rotating member is arranged between the fixing members; the rotating member is connected to the motor on the fixing member.

[0014] Furthermore, the rotating mechanism also includes: a rotating groove and a fixed rod;

[0015] The rotating groove is formed inside the rotating component; the fixing rod is fixedly disposed between the fixing components.

[0016] Furthermore, the cleaning mechanism includes: a movable component, a nozzle, and a connecting pipe;

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This device is equipped with anti-collision posts and magnetic posts. The anti-collision posts are located on the side of the fixed component, while the magnetic posts are located on both sides of the driving component. Thus, when the driving component moves and the magnetic posts approach the anti-collision posts, the opposite surfaces of the anti-collision posts and the magnetic posts are set with the same poles. Due to the principle that like poles of magnets repel each other, direct contact between the magnetic posts and the anti-collision posts can be avoided, thus achieving the anti-collision effect. This replaces the traditional anti-collision posts made of rubber and other materials, eliminates the need for periodic replacement, and makes the operation more stable.

[0020] 2. In this device, a rotating component and a moving component are provided. The rotating component is located between the fixed components, while the moving component is slidably mounted inside the rotating groove via a spherical protrusion. Thus, during use, the rotating component is driven to rotate by a motor on the fixed component, and the moving component, mounted inside the rotating groove via the spherical protrusion, is driven to reciprocate on the fixed rod by the rotating component. Furthermore, an external air source is connected through a connecting pipe, allowing compressed air to be sprayed out through the nozzle, thereby blowing away and cleaning impurities on the magnetic track and slide rail, preventing dust from adhering.

[0034] Among them, such as Figure 1 As shown, rectangular notches are provided on both sides of the main body 101; the slide rail 102 is set as an I-shaped structure; and the anti-collision post 104 is made of magnetic material.

[0037] Among them, such as Figure 3 As shown, the rotating mechanism 3 also includes a rotating groove 303 and a fixed rod 304; the rotating groove 303 is formed inside the rotating member 302; the fixed rod 304 is fixedly disposed between the fixed members 301; the rotating groove 303 here is used to slide and install the spherical protrusion on the moving member 401, so that when the rotating member 302 rotates, it can drive the moving member 401 to reciprocate on the fixed rod 304.

[0038] Among them, such as Figure 3As shown, the cleaning mechanism 4 includes: a movable part 401, a nozzle 402, and a connecting pipe 403; the movable part 401 is provided with a spherical protrusion, and the movable part 401 is slidably installed inside the rotating groove 303 through the spherical protrusion; the movable part 401 is slidably installed on the fixed rod 304; the nozzle 402 is located at the bottom of the movable part 401; the nozzle 402 is connected to the connecting pipe 403; the connecting pipe 403 is located on the side of the movable part 401; the connecting pipe 403 is connected to an external air source; the movable part 401 is used to slide inside the rotating groove 303 through the provided spherical protrusion, thereby driving the nozzle 402 to move back and forth, so as to clean dust and impurities in different locations; the connecting pipe 403 is used to connect to an external air source, which provides compressed air through an external compressed air tank or air compressor, and is equipped with a valve for control, all of which are conventional operations in the art.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In this invention, when using the device, the driving component 201 is connected to an external wire. When the coil on the driving component 201 is energized, a traveling wave magnetic field is generated. This magnetic field interacts with the static magnetic field formed by the magnetic track 103, creating a traveling wave magnetic field drive. This causes the driving component 201 to reciprocate on the slide rail 102. When the driving component 201 moves, if the magnetic column 202 approaches the anti-collision post 104, direct contact between the magnetic column 202 and the anti-collision post 104 can be avoided because the opposing surfaces of the anti-collision post 104 and the magnetic column 202 are set with the same poles. Due to the principle of repulsion between like poles of magnets, direct contact between the magnetic column 202 and the anti-collision post 104 can be avoided. It provides a collision protection effect, replacing the traditional rubber and other materials of the anti-collision post 104. It does not need to be replaced regularly and is more stable during operation. The rotating part 302 is driven to rotate by the motor on the fixed part 301, while the moving part 401 is set inside the rotating groove 303 by the spherical protrusion. The rotating part 302 drives the moving part 401 to move back and forth on the fixed rod 304. The air source is connected to the external air source through the connecting pipe 403, so that compressed air is sprayed out through the nozzle 402, which can blow away and clean impurities on the magnetic track 103 and the slide rail 102, and prevent dust from sticking.
