Technical Field
[0001] This utility model relates to the field of mechanical equipment module technology, specifically to a multi-actuator enclosed high-precision linear motor module. Background Technology
[0002] Linear modules, also known as linear robots, linear slides, etc., are automation upgrade units following linear guides and ball screw linear transmission mechanisms. Linear modules can achieve linear and curvilinear motion of loads through the combination of various units, making light-load automation more flexible and positioning more precise. In the field of non-standard automated mechanical linear motion, multiple motion controls need to be implemented in a limited space, requiring high speed, high load, and high precision, while also preventing interference between components. However, due to unreasonable design, these requirements are often not met. For example, in transmission modules, poor waterproofing and dustproofing can easily lead to water mist, dust, and other substances entering internal components such as movers and guides, causing rust and aging, resulting in insufficient transmission accuracy and short service life. Therefore, it is necessary to implement sealed protection for the internal structure of the module.
[0003] A search revealed a utility model patent with publication number CN209389914, which specifically discloses a multi-moving slide table enclosed high-precision linear motor module in the field of mechanical equipment module technology. The module includes a base, baffles mounted at both ends of the base, a guide rail mounted inside the base, and at least two sets of transmission seats mounted on the guide rail. Each set of transmission seats has a moving seat mounted on one side of the base, and a stator seat is separately provided on the base for each set of moving seats. The transmission seat includes a connecting part connected to the guide rail and the moving seat, and mounting parts connected to both sides of the connecting part. A groove is formed at the connection point between the connecting part and the mounting part. A sealing cover is mounted on the upper surface of the baffles at both ends, and the sealing cover is bent downwards on both sides to form sealing edges. The transmission seat can transmit power to the sealing edges through the grooves. This utility model achieves multiple transmission methods in one module, with good transmission effect, wide applicability, and good dust and water resistance. The sealing edges on both sides improve service life.
[0004] The aforementioned patent achieves multiple transmission methods on a single module and encapsulates the internal structure with a cover. Compared to traditional linear motor modules, this provides better sealing, dust and water resistance, and improved service life by sealing both sides with sealing edges. However, it cannot adequately detect and collect real-time temperature data for critical components (such as the stator, mover, and guide rail) during the operation of the electrode module. This makes it difficult to compensate for errors caused by deformation, thus affecting the stability and operational accuracy of the system.
[0005] Therefore, it is necessary to invent a multi-actuator enclosed high-precision linear motor module to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a multi-movement enclosed high-precision linear motor module. By using temperature sensors one, two, and three, it achieves real-time monitoring of temperature changes, collecting temperature data during high-speed movement of the stator, mover, guide, and slider, and transmitting this data to the controller system. The controller processes the collected temperature data, analyzing the temperature change trend and thermal deformation. This addresses the problem in existing technologies where temperature detection and real-time data collection for key components (such as the stator, mover, and guide rail) during operation are insufficient, making it difficult to compensate for errors caused by deformation, thus affecting system stability and operational accuracy.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-moving, enclosed, high-precision linear motor module, comprising a base, with guide seats symmetrically fixed inside the base, each guide seat having a fixing groove on its top, and a guide rail fixedly installed in each of the two fixing grooves, with at least two sets of transmission seats driven on the guide rails, each set of transmission seats having a moving seat installed on one side of the base corresponding to the moving seat, and a stator seat separately provided on the base for each set of moving seats, with sliders symmetrically fixed at the bottom of the transmission seats to match the guide rails, temperature sensors two fixedly installed inside each of the two guide seats, temperature sensor one fixedly installed inside the stator seat, and temperature sensor three fixedly installed inside the moving seat.
[0008] Preferably, a second heat pipe is fixedly provided inside the slider, and heat dissipation fins are distributed at equal intervals on both sides of the second heat pipe, with the heat dissipation fins extending to the bottom of one side and the other side of the slider, respectively.
[0009] Preferably, a heat pipe is fixedly installed inside the stator base, and heat dissipation fins are evenly distributed on both sides of the heat pipe, with the heat dissipation fins extending to the outside of the stator base.
[0010] Preferably, both ends of the base are equipped with end baffles, and an upper sealing cover is mounted on the upper surface of the two end baffles. The two sides of the upper sealing cover are bent downward to form sealing edges.
[0011] Preferably, both ends of the transmission seat are connected to the inner sides of the transmission seat with protrusions, and a groove is formed at the position where the transmission seat is connected to the protrusions.
[0012] Preferably, the base has support edges extending upwards on both sides, and the support edges are integrally formed with the base by wire drawing.
[0013] Preferably, a controller for controlling the linear motor drive is fixedly installed at the bottom of one side of the transmission base, and the controller is electrically connected to the mover base and the stator base.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] 1. By setting temperature sensor one, temperature sensor two, and temperature sensor three, temperature sensors one, temperature sensor two, and temperature sensor three are installed in key parts of the stator base, guide base, and mover base in the motor module to monitor temperature changes in real time, collect temperature data of the stator base and mover base, as well as the guide base and slider during high-speed movement, and transmit it to the controller system. The controller processes the collected temperature data, analyzes the temperature change trend and thermal deformation, and adjusts the position of the mover base by controlling the movement of the motor to compensate for errors caused by thermal deformation. It also adjusts the parameters of control current and voltage to maintain the stability and transmission accuracy of the system and module during operation.
[0016] 2. By configuring heat pipe one, heat dissipation fin one, heat pipe two, and heat dissipation fin two, and by properly installing heat pipe one in the slider and stator base, the temperature of key parts of the high-precision module can be effectively reduced, thermal deformation of the transmission structure can be reduced, and the stability and transmission accuracy of the system and module during operation can be improved. Since the stator base is the main heat-generating part of the motor, especially the internal coils which generate a lot of heat when energized, the installation of heat pipe one can effectively conduct the heat near the stator away with heat dissipation fin one, preventing excessive temperature rise. Since the mover base, together with the slider, guide rail, and guide seat, may generate heat due to friction or electromagnetic loss during high-speed movement, especially under high load or high acceleration conditions, heat pipe two can be used in conjunction with heat dissipation fin two to achieve auxiliary heat dissipation and reduce thermal deformation.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figure 1-5 The diagram shows a multi-mover enclosed high-precision linear motor module, including a base 1. Guide seats 10 are symmetrically fixed inside the base 1. Each guide seat 10 has a fixing groove 18 on its top, and a guide rail 5 is fixedly installed in each of the two fixing grooves 18. The fixing grooves 18 secure the guide rails 5, improving installation convenience and ensuring transmission stability and reliability. At least two sets of transmission seats 4 are installed on the guide rails 5. Each set of transmission seats 4 has a mover seat 8 installed on one side of the base 1. The base 1 has a separate stator seat 7 corresponding to each set of mover seats 8. The mover seat 8 and stator seat 7 cooperate to form a linear... The linear motor drives the transmission base 4 to move along the guide rail 5. Temperature sensors 11, 14, and 17 are installed in key parts of the stator base 7, guide base 10, and mover base 8 in the motor module to monitor temperature changes in real time and collect temperature data when the stator base 7 and mover base 8, as well as the guide base 10 and slider 6 are in high-speed motion. Since the mover base 8 may generate heat due to friction or electromagnetic loss when in high-speed motion with slider 6, guide rail 5, and guide base 10, especially under high load or high acceleration conditions, heat pipe 215 and heat dissipation fin 216 can be used to achieve auxiliary heat dissipation and reduce thermal deformation.
[0027] The bottom of the transmission base 4 is symmetrically fixed with sliders 6 that match the guide rail 5. Temperature sensors 14 are fixedly installed inside both guide bases 10. Temperature sensor 11 is fixedly installed inside the stator base 7. Temperature sensor 317 is fixedly installed inside the mover base 8. Heat pipes 12 are reasonably installed inside the sliders 6 and stator base 7, which can effectively reduce the temperature of key parts of the high-precision module, reduce thermal deformation of the transmission structure, and improve the stability and transmission accuracy of the system and module during operation. Since the stator base 7 is the main part of the motor that generates heat, especially the internal coils, which generate a lot of heat when energized, the installation of heat pipes 12 can effectively conduct the heat near the stator away with the heat dissipation fins 13, preventing excessive temperature rise.
[0028] The slider 6 is equipped with a heat pipe 15, and heat dissipation fins 16 are distributed at equal intervals on both sides of the heat pipe 15. The heat dissipation fins 16 distributed at equal intervals on both sides extend to the bottom of one side and the other side of the slider 6, respectively.
[0029] A heat pipe 12 is fixedly installed inside the stator base 7. Heat dissipation fins 13 are evenly distributed on both sides of the heat pipe 12. The heat dissipation fins 13 extend to the outside of the stator base 7. The heat dissipation fins 13 and 16 are specifically aluminum alloy fins. The surface of the aluminum alloy fins has a ceramic coating formed by TECO (thermochemical oxidation) treatment to increase its heat dissipation performance and durability.
[0030] Both ends of the base 1 are equipped with end baffles 3. The upper surface of the two end baffles 3 is covered with an upper encapsulation cover 2. The two sides of the upper encapsulation cover 2 are bent downward to form sealing edges 201. The sealing edges 201 work with the groove 402 to achieve auxiliary transmission. The fit of the structure provides a good sealing effect.
[0031] Both ends of the transmission seat 4 are connected to the inner side of the flange 401. A groove 402 is provided at the position where the transmission seat 4 is connected to the flange 401. The structure of the flange 401 allows the upper sealing cover 2 to be better covered on the top of the transmission seat 4.
[0032] The transmission seat 4 can be driven to the sealing edge 201 through the groove 402. The sealing edge 201 is integrally stretched and formed on both sides of the upper sealing cover 2. It is also drawn, which makes the overall strength high, the deformation resistance good, the practicality strong and the reliability strong.
[0033] The base 1 has support edges 101 extending upwards on both sides. The support edges 101 are integrally formed with the base 1 by wire drawing. While ensuring support, they can also work with the sealing edge 201 to seal and protect both sides, providing good protection and improving service life.
[0034] A controller 9 for controlling the linear motor drive is fixedly installed on the bottom of one side of the transmission base 4. The controller 9 is electrically connected to the mover base 8 and the stator base 7. The linear motor is controlled by the controller 9 to achieve transmission. Each group is equipped with a separate controller 9 to achieve intelligent control, good control effect and strong practicality. The controller 9 processes the collected temperature data, analyzes the temperature change trend and thermal deformation, and adjusts the position of the mover base 8 by controlling the movement of the motor to compensate for the error caused by thermal deformation.
[0035] The transmission seat 4, the raised edge 401, and the recess 402 are integrally machined. The integrally machined transmission seat 4 has high strength and connection strength, which improves the transmission effect and service life. The position where the transmission seat 4 connects with the recess 402 is provided with an arc surface, and the raised edge 401 is provided with a structure corresponding to the arc surface. The purpose of providing the arc surface and the raised surface structure is to facilitate the installation and use of the upper sealing cover 2. The insertion method of the sealing method can further improve the sealing effect.
[0036] The working principle of this practical application is as follows:
[0037] The controller 9 is connected to the stator base 7 and the mover base 8. The controller 9 controls the linear motor to achieve transmission. Each group is equipped with a separate controller 9 to achieve intelligent control. The guide rail 5 is fixedly installed through the fixing slot 18 to improve the ease of installation of the guide rail 5. The mover base 8 and the stator base 7 cooperate to form a linear motor drive transmission seat 4 to drive along the guide rail 5. Heat pipe 12 and heat pipe 25 are pre-embedded in the stator base 7 and the slider 6 respectively, and heat dissipation fins 13 and 216 are used to achieve heat conduction at the structure.
[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
