Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a linear translation device. Background Technology

[0002] Precision stages are commonly used to move target objects, such as linearly displacing a sample under test. Existing stages typically use rod motors to drive the motion mechanism and thus the linear displacement of the object. However, due to the narrow mounting clearance of rod motors and the tendency of the magnetic rod to buckle after reaching a certain length, the moving and stating elements are prone to scraping during movement, compromising the stability of the device. Furthermore, when the stage is placed on a metal worktable, the exposed magnetic rod will attract the metal surface, interfering with the feedback accuracy of the control system and affecting the stability of the servo control. Simultaneously, rod motors struggle to handle long strokes, and excessively long magnetic rods exacerbate deformation, posing significant challenges to installation and maintenance. All of these factors affect the motion accuracy of the stage and increase the cost of equipment installation and maintenance. Utility Model Content

It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] The following describes a linear translation device provided by an embodiment of this utility model with reference to the accompanying drawings. Figure 1-10 The linear translation device includes a main body 1, a sliding mechanism 2, a driving mechanism 3, and a flexible chain assembly 4.

[0056] refer to Figure 1-2 The main body 1 is provided with an installation cavity 11; the sliding mechanism 2 includes a sliding component 21 and a guide component 22 that are slidably connected. The guide component 22 is fixedly mounted on the main body 1, and the sliding component 21 is used to connect with the object to be loaded. The main body 1 integrates the sliding component 21 and the guide component 22, and an object bearing position is provided on the sliding component 21 to fix the object to be loaded.

[0057] refer to Figure 1 and Figure 3 The drive mechanism 3 is disposed in the mounting cavity 11 and includes a non-magnetic motor assembly 31 and a magnetic stator assembly 32. The non-magnetic motor assembly 31 is electrically connected to the power supply and electromagnetically coupled to the magnetic stator assembly 32. The non-magnetic motor assembly 31 is drively connected to the sliding assembly 21. The magnetic stator assembly 32 may include a permanent magnet. The battery cell material of the non-magnetic motor assembly 31 is a non-magnetic material. When energized, the non-magnetic motor assembly 31 generates an electromagnetic field and electromagnetically couples with the magnetic stator assembly 32, thereby providing a driving force to drive the sliding assembly 21 to move along the guide assembly 22.

[0058] refer to Figure 1 and Figure 3The flexible chain assembly 4 is disposed in the mounting cavity 11, including a chain body 41 with a wire harness receiving cavity, and a chain fixed end 42 and a chain moving end 43 located at both ends of the chain body 41. The chain fixed end 42 is fixedly connected to the inner wall of the mounting cavity 11, and the non-magnetic motor assembly 31 is drivenly connected to the chain moving end 43. The wire harness of the linear translation device can be accommodated in the wire harness receiving cavity and its two ends extend out to connect to the corresponding components.

[0059] When the non-magnetic motor assembly 31 is energized, it can be driven by the magnetic field of the magnetic stator assembly 32 to move the sliding assembly 21 and the chain moving end 43 relative to the guide assembly 22. The chain body 41 deforms as the chain moving end 43 moves, thereby driving the deformation and movement of the wire harness.

[0060] In summary, the linear translation device of this application comprises a main body 1, a sliding mechanism 2, and a flexible chain assembly 4. A drive mechanism 3 and a flexible chain assembly 4 are disposed in the mounting cavity 11 of the main body 1. The sliding mechanism 2 includes a sliding assembly 21 and a guide assembly 22 that are slidably connected. The flexible chain assembly 4 includes a chain body 41 with a wire harness accommodating cavity, and a chain fixed end 42 and a chain moving end 43 located at both ends of the chain body 41. The drive mechanism 3 includes a non-magnetic motor assembly 31 and a magnetic stator assembly 32, which provide driving force through electromagnetic coupling. The device generates less friction during movement, occupies less space, has a low magnetic force on the metal worktable, and is not limited by the length of the driving displacement. It satisfies the requirements of movement stability and displacement accuracy while avoiding deformation of the motor and the worktable. It also provides sufficient installation space for the flexible chain assembly 4 to concentrate the wire harness. Furthermore, a non-magnetic motor assembly 31 is connected to the sliding assembly 21 and the chain moving end 43 respectively to drive the sliding assembly 21 and the chain moving end 43 to move in tandem, thereby providing wire harness protection and freedom of movement while concentrating the wire harness.

[0061] In possible implementations, refer to Figure 3 The sliding component 21 slides along the sliding direction defined by the guide component 22 under the drive of the non-magnetic motor component 31. The magnetic stator component 32 includes multiple magnetic stators 321, which are spliced ​​together along the sliding direction of the sliding component 21. The number of magnetic stators 321 is positively correlated with the movable stroke of the non-magnetic motor component 31. In this way, by limiting the movable stroke of the non-magnetic motor component 31 through the spliced ​​multiple stator segments, the movable range of the sliding component 21 is limited, thereby realizing the free control and adjustment of the object's movement stroke.

[0062] In possible implementations, refer to Figure 1 and Figure 2 The guide component 22 restricts the sliding direction of the sliding component 21. Preferably, the guide component 22 can restrict the sliding component 21 to move in a straight line relative to the carrier body 1, that is, the movable stroke of the sliding component 21 is a straight stroke.

[0063] In a possible implementation, the magnetic stator assembly 32 can drive the energized, non-magnetic motor assembly 31 to move along a linear direction restricted by the guide assembly 22. Using a non-magnetic motor assembly eliminates hysteresis losses and cogging effects caused by magnetic materials such as iron cores. When energized, the electromagnetic field generated by the non-magnetic motor assembly 31 and the magnetic field formed by the magnetic stator assembly 32 produce a Lorentz force, propelling the non-magnetic motor assembly 31 and the sliding assembly 21 to slide linearly along the guide assembly 22. This ensures precise control of object displacement and reduces component wear, thereby ensuring the accuracy and stability of object movement and reducing the risk of component deformation. In some embodiments, the non-magnetic motor assembly 31 includes a coreless linear motor. Coreless linear motors have a compact structure, occupying less space in the same volume, further increasing the installation space of the flexible chain assembly 4.

[0064] In some embodiments, the magnetic stator assembly 32 can be made of high-performance permanent magnets, with multiple stators arranged and spliced ​​to form a periodic magnetic field. The non-magnetic motor assembly 31 can include multiple sets of non-magnetic wire coils and a non-magnetic material body for fixing the wires. For example, the non-magnetic wire coils can be copper wire coils. When current passes through the non-magnetic wire coils, the current-carrying wires are subjected to Lorentz force in the magnetic field of the permanent magnets of the stator. The multiple sets of wire coils are arranged in a specific phase. By controlling the direction and magnitude of the current, the forces generated by each wire coil are aligned, forming a resultant force that drives the non-magnetic motor assembly 31 to move linearly. Preferably, the multiple sets of non-magnetic wire coils can be wound into a flat shape.

[0065] In possible implementations, refer to Figure 1 , Figure 3 and Figure 6 The linear translation device also includes a detection component 5, which includes a correspondingly set grating ruler 51 and a reading head 52. The grating ruler 51 is fixedly set on the inner wall of the mounting cavity 11, and the reading head 52 is fixedly connected to the non-magnetic motor assembly 31. During the movement of the sliding assembly 21 relative to the guide assembly 22, the reading head 52 moves relative to the grating ruler 51, and the movement stroke of the sliding assembly 21 is consistent with the movement stroke of the reading head 52. The inner wall of the mounting cavity 11 is provided with a grating ruler positioning mounting position to quickly position and install the grating ruler 51. The reading head 52 and the sliding assembly 21 are set to move together so that the sliding assembly 21 generates a displacement relative to the grating ruler 51 during its movement, thereby reading the displacement amount and realizing precise control of the displacement of the sliding assembly 21, thereby improving the high-precision movement control of the object to be loaded.

[0066] Specifically, the length direction of the grating ruler 51 is consistent with the sliding direction of the sliding component 21, and the reading head 52 is located on the side of the non-magnetic motor component 31 facing the inner wall of the mounting cavity 11.

[0067] In possible implementations, refer to Figure 1 The magnetless motor assembly 31 includes a coreless motor 311 and a motor mounting plate 312. The coreless motor 311, the chain moving end 43, and the reading head 52 are fixedly mounted on the motor mounting plate 312. The motor mounting plate 312 is fixedly connected to the sliding assembly 21, and there is a gap between the motor mounting plate 312 and the inner wall of the mounting cavity 11 to avoid interference with the movement of the motor mounting plate 312 within the mounting cavity 11. The coreless motor 311 can move in coordination with the motor mounting plate 312, the chain moving end 43, and the reading head 52. In this way, by integrating the coreless motor 311, the chain moving end 43, and the reading head 52 through the motor mounting plate 312, the compactness of the device structure is improved, the stroke consistency of the sliding assembly 21 and the reading head 52 is ensured, and the stability of the wiring harness connection is also ensured.

[0068] Specifically, refer to Figure 3-4 The coreless motor 311 is positioned near the magnetic stator assembly 32 to facilitate electromagnetic coupling between the magnetic stator assembly 32 and the coreless motor assembly 31.

[0069] In possible implementations, refer to Figure 1 The drive mechanism 3 also includes a buffer 33, which is disposed on the side end of the motor mounting plate 312 in the direction of movement. When the motor mounting plate 312 moves to the limit position relative to the mounting cavity 11, the buffer 33 separates the motor mounting plate 312 and the cavity side wall of the mounting cavity 11 to achieve motion buffering when the motor mounting plate 312 moves to the side wall of the mounting cavity 11, so as to avoid component damage and motion accuracy affected by hard contact.

[0070] Preferably, the motor mounting plate 312 is provided with buffers 33 on both sides in its moving direction to ensure abutment buffer at bidirectional extreme positions.

[0071] In possible implementations, refer to Figure 1 The flexible chain assembly 4 also includes a movable end mounting member 44 and a fixed end mounting member 45. The non-magnetic motor assembly 31 is connected to the movable end 43 of the chain via the movable end mounting member 44. One end of the fixed end mounting member 45 is fixedly connected to the inner wall of the mounting cavity 11, and the other end of the fixed end mounting member 45 is fixedly connected to the chain body 41. The fixed end mounting member 45 and the movable end 43 define a bendable section of the chain body 41. In this way, the fixed end mounting member 45 forms an inner wall connection position of the chain body 41, which, combined with the inner wall connection position of the fixed end 42, forms a fixed section of the chain body 41, further improving the motion stability of the flexible chain, protecting the wire harness and extending its service life, while also improving the flexibility and ease of maintenance of the movable end of the wire harness. Furthermore, the movable end 43 of the chain is integrated into the non-magnetic motor assembly 31 via the movable end mounting member 44, improving the connection stability of the movable end 43.

[0072] Preferably, refer to Figure 1Both the chain fixing end 42 and the fixing end mounting part 45 are fixedly connected to the inner wall of the mounting cavity 11 on the side facing the sliding mechanism 2, so as to facilitate the movement of the chain body 41 and the use of space.

[0073] Preferably, refer to Figure 1 The mobile terminal mounting component 44 is integrated and mounted on the motor mounting plate 312, further improving the compactness of the device and the consistency of the stroke.

[0074] In possible implementations, refer to Figure 7-9 The guide assembly 22 includes a slide rail fixedly connected to the load body 1, and the sliding assembly 21 includes a slide plate 211, a slider 212, and a transmission connector 213. The slide plate 211 carries the object to be carried, and the object-bearing position is set on the slide plate 211 to fix the object. The slider 212 is slidably connected to the slide rail and fixedly connected to the slide plate 211, and the slide plate 211 is slidably connected to the slide rail via the slider 212. The transmission connector 213 is fixedly connected to the slide plate 211 and is drively connected to the non-magnetic motor assembly 31, which drives the slide plate 211 and the slider 212 to move relative to the slide rail through the transmission connector 213. Thus, the connection between the slide rail, slide plate 211, slider 212, transmission connector 213, and non-magnetic motor assembly 31 enables the non-magnetic motor assembly 31 to drive the movement of the slide plate 211 and ensures the stability of the slide plate 211's movement.

[0075] Preferably, the slide rail is a linear guide rail, and the slider 212 is a slider that matches the slide rail.

[0076] In a possible implementation, the slide rail includes a first slide rail 221, as shown in the reference. Figure 2 and Figure 7-9 The sliding component 21 is disposed on the top surface of the main body 1, and the object bearing position is disposed on the top surface of the slide plate 211. The upper end of the sliding member 212 is fixedly connected to the bottom surface of the slide plate 211, and the lower end of the sliding member 212 is slidably connected to the upper end of the first slide rail 221. The lower end of the first slide rail 221 is fixedly connected to the main body 1. The upper end of the transmission connector 213 is fixedly connected to the bottom surface of the slide plate 211, and the lower end of the transmission connector 213 extends into the mounting cavity 11 and is fixedly connected to the non-magnetic motor assembly 31 to achieve linkage.

[0077] In possible implementations, refer to Figure 2 The slide rail includes a first slide rail 221 and a second slide rail 222 arranged in parallel; the second slide rail 222 is fixedly connected to the main body 1, and the guiding directions of the first slide rail 221 and the second slide rail 222 are consistent.

[0078] In some embodiments, reference is made to Figure 8The number of sliding parts 212 is set to four, and the four sliding parts 212 are symmetrically arranged in pairs on the first slide rail 221 and the second slide rail 222.

[0079] In possible implementations, refer to Figure 4-5 The mounting cavity 11 includes a channel 111 arranged along the sliding direction of the sliding assembly 21. One end of the transmission connector 213 is fixedly connected to the slide plate 211, and the other end of the transmission connector 213 extends into the channel 111 and is connected to the non-magnetic motor assembly 31. The non-magnetic motor assembly 31 can drive the transmission connector 213 to move within the channel 111. Thus, the channel 111 is provided to effectively utilize the cavity space of the carrying body 1, limit the range of motion of the transmission connector 213, ensure the stability of the sliding assembly 21's movement, and facilitate device assembly. A gap exists between the transmission connector 213 and the side wall of the channel 111 to avoid motion interference.

[0080] Preferably, one end of the transmission connector 213 is fixedly connected to the slide plate 211, and the other end of the transmission connector 213 extends out of the channel 111 and is fixedly connected to the motor mounting plate 312, thereby further improving the integration of the device.

[0081] In possible implementations, refer to Figure 4-5 The mounting cavity 11 also includes a receiving groove 112 and a partition wall 113, with the receiving groove 112 and the channel 111 separated by the partition wall 113. The chain moving end 43 is located in the receiving groove 112, and a portion of the non-magnetic motor assembly 31 is housed in the receiving groove 112. Thus, by housing the chain moving end 43 and a portion of the non-magnetic motor assembly 31 in the receiving groove 112, the drive mechanism 3 and the flexible chain assembly 4 are easily integrated into the mounting cavity 11, effectively utilizing the cavity space and ensuring that the chain body 41 has sufficient space for movement and deformation while improving the compactness of the device.

[0082] In one embodiment, the magnetic stator assembly 32 is disposed at one end of the channel 111 facing the bottom surface of the loading body 1, and the coreless motor 311 is disposed at an interval from the magnetic stator assembly 32.

[0083] Preferably, refer to Figure 1 , Figure 3 and Figure 4 The detection component 5 is located in the receiving groove 112, the grating ruler 51 is set on the side wall of the receiving groove 112, and the motor mounting plate 312 is partially located in the receiving groove 112 and integrates the reading head 52, so as to facilitate the installation of the flexible chain component 4 and avoid the movement space of the chain body 41.

[0084] In possible implementations, refer to Figure 7-9The bottom wall and side wall of the accommodating groove 112 form a protruding structure 12 located on the top surface of the carrying body 1. The protruding structure 12 is located between the first main body side wall 13 and the second main body side wall 14 of the carrying body 1. A first guide rail channel 15 is formed between the protruding structure 12 and the first main body side wall 13 to accommodate the first slide rail 221. A second guide rail channel 16 is formed between the protruding structure 12 and the second main body side wall 14 to accommodate the second slide rail 222, thereby further effectively utilizing the space of the carrying body 1. The sliding plate 211 spans the guide rail channel 15, the protruding structure 12, and the second guide rail channel 16, and has a gap with the protruding structure 12 to avoid motion interference. During the movement of the sliding plate 211 driven by the non-magnetic motor assembly 31, the sliding member 212 slides relative to the slide rail in the guide rail channel, and the transmission connector 213 moves in the channel 111. In this way, the non-magnetic motor assembly 31, transmission connector 213, and first slide rail 221, second slide rail 222, and sliding member 212 on the top side of the loading body 1 are highly integrated through the concave-convex design, thereby effectively utilizing the internal and external space of the loading body 1, ensuring the smooth movement of the slide plate 211 while further improving the integration of the device.

A guide rail channel 15 is formed in the gap between the first main body sidewall 13 and the sidewall of the protruding structure 12. A first slide rail 221 is located at the bottom of the guide rail channel 15, and two sliding members 212 are slidably engaged on the first slide rail 221. A guide rail channel 16 is formed in the gap between the second main body sidewall 14 and the sidewall of the protruding structure 12. A second slide rail 222 is located at the bottom of the guide rail channel 16, and two other sliding members 212 are slidably engaged on the second slide rail 222. The first slide rail 221 and the second slide rail 222 are arranged parallel to each other. Further, refer to... Figure 9 The bottom surface of the slide plate 211 faces the first guide rail channel 15, the protruding structure 12, and the second guide rail channel 16, and spans across the first guide rail channel 15, the protruding structure 12, and the second guide rail channel 16 to be fixedly connected to the sliding member 212 and the transmission connector 213. The drive mechanism 3 is located in the mounting cavity 11 and is connected to the slide plate 211 via the transmission connector 213. The drive mechanism 3 drives the slide plate 211 and the sliding member 212 to slide relative to the first slide rail 221 and the second slide rail 222 through the drive transmission connector 213. The first slide rail 221 and the second slide rail 222 together limit the movement direction of the slide plate 211.

[0089] In possible implementations, refer to Figure 9 The linear translation device also includes a sliding fixing member 6, comprising a first connecting end detachably and fixedly connected to the sliding assembly 21 and a second connecting end detachably and fixedly connected to the load body 1. The sliding fixing member 6 can restrict the relative movement between the sliding assembly 21 and the guide assembly 22, thereby fixing the slide plate 211 during device transportation and preventing damage to the sliding mechanism 2 during transportation. Optionally, the number of sliding fixing members 6 is one, or two or more sliding fixing members 6 are provided, with the two or more sliding fixing members 6 distributed at both ends of the slide plate 211 to improve the stability of the slide plate 211 during device transportation.

The non-magnetic base plate 17 and the sliding mechanism 2 are disposed opposite each other on both sides of the mounting cavity 11. The mounting cavity 11 is magnetically shielded from the outside by the non-magnetic base plate 17. The non-magnetic base plate 17 is located on the bottom side of the carrier body 1 and is made of non-magnetic material to isolate magnetic fields and prevent the permanent magnet inside the magnetic stator assembly 32 from being magnetically attracted to the ferromagnetic material working platform. It also prevents the magnetic field from affecting the precision optical system that the linear translation device may support. Furthermore, it isolates the magnetic field of the drive mechanism 3 from interfering with the external magnetic field, improving the compatibility of the device.

[0093] In possible implementations, refer to Figure 9 The linear translation device also includes at least one lifting member 7, which is detachably and fixedly connected to the main body 1 and located on the top surface of the main body 1, facilitating the movement of the linear translation device. Preferably, lifting members 7 are provided at both ends of the long side of the main body 1 to facilitate the translation of the linear translation device.
