Description

Technical Field

[0001] This utility model relates to the field of linear motors, and in particular to a single-axis mover splicable linear motor module. Background Technology

[0002] In the context of Industry 4.0, driven by fields such as semiconductor manufacturing, new energy vehicles, medical equipment, and aerospace, linear motors are developing towards higher precision, higher efficiency, and greater intelligence. With the continuous advancement of materials science and control technology, the application demand for linear motor modules in various fields is increasing. Traditional linear motor modules with fixed-length movers cannot fully meet the needs of various working conditions and have the following shortcomings:

[0003] 1. The maximum output of linear motors is limited. In linear motion requiring heavy loads, linear motors equipped with fixed series movers may not meet the needs.

[0004] 2. Waste of resources: When used in short strokes or with small loads, the fixed-length mover may have an underutilized portion, resulting in low utilization and waste of materials.

[0005] 3. Precise alignment is required during the installation of the mover; the installation is more difficult when the fixed length mover is relatively long.

[0006] 4. During long-stroke motion, the energy loss of a fixed-length mover may increase due to operational or on-site reasons, thus increasing operating costs. When the mover is worn, the maintenance cost is also high.

[0007] 5. For linear motors with fixed-length movers, the uniformity of the magnetic field distribution and the influence of edge effects on motion must be considered. Furthermore, when the mover length is long, the mover mass is large, which increases the system inertia.

[0008] 6. Linear motors with fixed-length movers have poor application flexibility and cannot be used flexibly in situations with large loads or high operating requirements. When the operating conditions need to be expanded, linear motors with fixed-length movers may need to be redesigned. Utility Model Content

Detailed Implementation

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, embodiments of this application disclose a single-axis mover-configurable linear motor module, including a base, a stator module mounted on the base, guide rails 2 on both sides of the stator module, the guide rails 2 being mounted on the base, and a mover module that cooperates with the stator module. The mover module is slidably connected to the guide rails 2. The mover module includes a first splicing mover unit 3, n second mover splicing units 4, and a third mover splicing unit 5. The first splicing mover unit 3, the n second mover splicing units 4, and the third mover splicing unit 5 are sequentially spliced ​​and connected, so that the spliced ​​mover module can move under the action of the stator module.

[0033] In actual operation, the number of second mover splicing units 4 can be selected according to the actual working conditions. The number of disc mover splicing units can be 0, 1, 2, 3, 4, etc. After splicing, the first splicing mover unit 3, n second mover splicing units 4 and the third mover splicing unit 5 can form a complete mover module. Under the action of the magnetic field generated by the stator module, the mover module can move linearly along the guide rail 2.

[0034] The design of this structure, through the splicing of moving sub-units, allows for the addition or reduction of the number of moving sub-units as needed to meet different working conditions.

[0035] In this embodiment, as Figures 3 to 8 As shown, the first splicing moving sub-unit 3 includes a first moving sub-base 301, a first moving sub-unit 302 is provided at the bottom of the first moving sub-base 301, a connecting line 303 is provided on one side of the first moving sub-unit 302, and a first connector 304 is provided on the other side of the first moving sub-unit 302.

[0036] The second splicing moving subunit includes a second moving subbase 401, a second moving subunit 402 is provided at the bottom of the second moving subbase 401, and a second connector 403 and a third connector 404 are respectively provided on both sides of the second moving subunit 402. The second connector 403 is used to mate and plug with the first connector 304.

[0037] The third splicing moving subunit includes a third moving sub-base 501, and a third moving subunit 502 is provided at the bottom of the third moving sub-base 501. A fourth connector 503 is provided on one side of the third moving subunit 502. The fourth connector 503 is used to mate and plug with the first connector 304 or the third connector 404. An encapsulation plate 504 is provided on the other side of the third moving subunit 502.

[0038] It should be explained that, in the first connector 304 and the second connector 403, one is a male connector and the other is a female connector; similarly, in the third connector 404 and the fourth connector 503, one is a male connector and the other is a female connector. This design ensures a stable and accurate connection between the various moving part splicing units. This design makes the splicing process of the moving part module simpler and faster, while also ensuring that the spliced ​​moving part module has good stability and operational performance.

[0039] It should be explained that the first moving sub-unit 302, the second moving sub-unit 402 and the third moving sub-unit 502 all include a moving body and a control circuit board connected to the moving body. When splicing is achieved, the signals of each control circuit board are connected.

[0040] In practical use, the first, second, and third splicing moving units are assembled sequentially in a predetermined order. First, one end of the first splicing moving unit 3 is connected to the second connector 403 on one end of the second splicing moving unit via its first connector 304, ensuring a secure connection. Next, the number of second splicing moving units can be increased sequentially according to the required stroke length. Each second splicing moving unit is connected to the preceding and following moving units via its second connectors 403 and third connectors 404 on both sides. Finally, one end of the third splicing moving unit is connected to the third connector 404 on the last second splicing moving unit via its fourth connector 503, completing the assembly of the entire moving module.

[0041] During the assembly process, the connection between each moving splicing unit is not only stable, but also the standardized connector design makes the splicing process simpler and faster, without the need for complicated alignment and adjustment steps.

[0042] In practical use, both the stator and the mover are energized. After energization, the stator module generates a magnetic field, which interacts with the mover unit in the mover module, thereby driving the mover module to move linearly along guide rail 2. Because the mover module adopts a modular design, the number of mover units can be flexibly adjusted according to actual working conditions to achieve linear motion of different stroke lengths.

[0043] In this embodiment, the first splicing moving sub-unit 3, the second moving sub-splitting unit 4 and the third moving sub-splitting unit 5 all include a slider 6 that is slidably connected to the guide rail 2. An integrated oil injection nozzle 7 for supplying oil to the steel balls inside the slider 6 is provided on one side of the slider 6.

[0044] Specifically, the integrated grease nipple 7 design allows users to easily lubricate the steel balls inside the slider 6 during use, thereby reducing friction between the slider 6 and the guide rail 2 and improving the smoothness and service life of the moving module. When lubrication is required, users only need to inject an appropriate amount of lubricating oil into the slider 6 through the integrated grease nipple 7 to achieve effective lubrication of the slider 6.

[0045] In this embodiment, both the sliders 6 of the first splicing moving sub-unit 3 and the second moving sub-splitting unit 4 are provided with oil supply channels. One end of the oil supply channel is provided with the integrated oil injection nozzle 7, and the other end of the oil supply channel is used to connect with the integrated oil injection nozzle 7 of the rear slider 6.

[0046] Specifically, the oil supply channel design allows lubricating oil to be transferred between multiple sliders 6, thus achieving effective lubrication of the entire moving part module. During use, the user only needs to lubricate the first slider 6, and the lubricating oil will be sequentially transferred to the subsequent sliders 6 through the oil supply channel, providing sufficient lubrication for the steel balls inside the sliders 6. This design not only simplifies the lubrication operation but also improves the lubrication effect, further extending the service life of the moving part module.

[0047] In this embodiment, a photoelectric sensor 8 for travel detection is provided on one side of the base, and a detection piece 9 that cooperates with the photoelectric sensor 8 is provided on one side of the first splicing mover unit 3, the second mover splicing unit 4, or the third mover splicing unit 5.

[0048] Specifically, the arrangement of photoelectric sensor 8 and detection plate 9 enables precise detection of the movement stroke of the moving module. During the movement of the moving module, detection plate 9 moves along with it. When detection plate 9 moves into the detection range of photoelectric sensor 8, photoelectric sensor 8 sends a signal, thereby achieving precise control of the movement stroke of the moving module. This design not only improves the accuracy and stability of the moving module's movement but also allows users to flexibly adjust the movement stroke of the moving module according to actual needs.

[0049] In this embodiment, a cover plate 10 and side plates 11 located on both sides of the cover plate 10 are also included. The side plates 11 are respectively connected to the cover plate 10 and the base by bolts, so that the first splicing moving sub-unit 3, the second moving sub-splitting unit 4 and the third moving sub-splitting unit 5 are located between the cover plate 10 and the base.

[0050] Specifically, the design of the cover plate 10 and side plate 11 not only provides a closed and stable operating environment for the mover module, but also effectively prevents external factors from interfering with its operation. Simultaneously, the bolted connection ensures that the cover plate 10 and side plate 11 are firmly fixed to the base, improving the structural strength of the entire linear motor module. During use, users can disassemble or install the cover plate 10 and side plate 11 according to actual needs for maintenance or replacement of the mover module.

[0051] In addition, when the linear motor stroke is short, the cover plate 10 can be made of plastic material, so that the cover plate 10 can be fixed by a press-type buckle. When disassembling, the cover plate 10 can be removed directly without removing the end cover first, which reduces the difficulty of installation and disassembly.

[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
