Description

Technical Field

[0001] This invention relates to the field of automated transmission components technology, and in particular to a high-speed, high-temperature resistant linear transmission module and its control method. Background Technology

[0002] Linear drive modules, also known as linear slides, linear cylinders, or robotic arms, are highly integrated transmission platforms specifically designed for the production of precision functional components. They are optimized and upgraded based on linear guides, combining linear guide sliders and linear guide blocks to form a more compact transmission mechanism. Through the combination of various units, linear modules can achieve linear motion of loads, making automation of light loads more flexible and positioning more precise. Their working principles mainly include two types: synchronous belt drive and ball screw drive. Synchronous belt drive modules achieve linear motion through components such as belts, linear guides, and sliders, while ball screw drive modules achieve high-precision linear motion through components such as ball screws and linear guides. Linear modules have wide applications in manufacturing, electronic equipment, medical equipment, communication engineering, agricultural machinery, logistics and transportation, environmental protection equipment, and military equipment. For example, in automobile manufacturing, linear modules are used for transporting and assembling automotive parts; in the medical equipment field, linear modules are used in precision equipment such as surgical robots and medical microscopes.

[0003] In some manufacturing industries, linear modules require high-speed reciprocating transmission to support high-speed automated production. However, this high-speed transmission generates significant heat. Existing linear modules are unable to effectively dissipate heat during high-speed transmission, necessitating a redesign of the existing linear module structure. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a high-speed, high-temperature resistant linear transmission module and control method that can adapt to different working environments and task requirements by flexibly adjusting control parameters. Whether it is stable operation in high-temperature environments or precise control under high-speed transmission, it can demonstrate excellent performance.

[0005] The technical solution adopted in this invention is: a high-speed, high-temperature resistant linear transmission module, including a transmission component, a drive component, and a circulating heat dissipation component. The transmission component includes a base, a transmission guide rail, a transmission screw, a fixed end plate, and a transmission seat. There are two sets of transmission guide rails, which are respectively arranged on both sides of the base. There are two sets of fixed end plates, which are respectively arranged at both ends of the base. The two ends of the transmission screw are mounted on the fixed end plates. The transmission seat is arranged on the transmission guide rail and connected to the transmission screw. The drive component is arranged on the base and is used to drive the transmission screw to drive the transmission seat to slide along the transmission guide rail.

[0006] The circulating heat dissipation assembly includes a control system, a cooling circulation transmission module, and a transmission control module. The control system is electrically connected to the cooling circulation transmission module and the drive assembly. The cooling circulation transmission module includes a first guide rail channel, a first lower channel, a second lower channel, a lead screw channel, a third lower channel, and a second guide rail channel. The first and second guide rail channels are respectively disposed on two sets of transmission guide rails and pass through the length of the transmission guide rails. The first, second, and third lower channels all pass through the length of the base. The lead screw channel passes through the length of the transmission lead screw. One end of the first guide rail channel is connected to the transmission control module, and the other end is provided with a first connection. The component is connected to a first downstream channel. A second connecting element is provided at one end of the first downstream channel. One end of the second connecting element is connected to the second downstream channel. A third connecting element is provided at one end of the second downstream channel and connected to a lead screw channel. One end of the third connecting element is rotatably connected to the lead screw channel. A fourth connecting element is rotatably connected at one end of the lead screw channel. One end of the fourth connecting element is connected to the third downstream channel. A fifth connecting element is provided at one end of the third downstream channel and connected to a second guide rail channel. One end of the second guide rail channel is connected to a transmission control module. The transmission control module is used to supply liquid to the first guide rail channel, and the second guide rail channel returns liquid to the transmission control module.

[0007] A further improvement to the above solution is that the base is provided with multiple heat dissipation holes, which extend along the length of the base. There are multiple sets of heat dissipation holes, with two holes in each set. The multiple sets of heat dissipation holes are respectively located on both sides of the first lower channel, the second lower channel, and the third lower channel for heat dissipation.

[0008] A further improvement to the above solution is that the base has mounting grooves on both sides, and multiple mounting countersunk holes are provided on the mounting grooves. The mounting countersunk holes extend along the thickness direction of the base. One side of the transmission guide rail is provided on the mounting groove, and mounting screws are provided on the mounting countersunk holes to fix the transmission guide rail on the mounting groove. The base has multiple fixing countersunk holes for fixing the base.

[0009] A further improvement to the above solution is that the transmission guide rail includes a guide rail body and a guide rail slider. The guide rail slider is slidably disposed on the guide rail body. Guide rail grooves are provided on both sides of the guide rail body. A heat dissipation surface is provided on the upper surface of the guide rail body. A heat dissipation gap is provided between the guide rail slider and the heat dissipation surface. A heat dissipation groove is provided on the heat dissipation surface to dissipate heat from the guide rail groove. The first guide rail flow channel is close to the heat dissipation surface and the guide rail groove. The guide rail slider is provided with a sliding engagement part, which is disposed on the guide rail groove.

[0010] A further improvement to the above solution is that a temperature sensing element is provided on the guide rail slider, and a connecting slot is provided on the guide rail slider. One end of the temperature sensing element is inserted into the connecting slot and close to the guide rail groove. The temperature sensing element is used to sense the temperature generated by the high-speed friction between the guide rail slider and the guide rail groove. The control system is electrically connected to the temperature sensing element and receives the temperature parameters sensed by the temperature sensing element. The control system controls the transmission speed of the transmission control module according to the temperature parameters.

[0011] A further improvement to the above scheme is that the fixed end plate is provided with a rotating fixing hole, a rotating bearing is provided on the rotating fixing hole, the transmission screw is provided on the rotating bearing, the transmission seat is provided with a screw nut, the transmission seat is threadedly connected to the transmission screw through the screw nut, the transmission screw is provided with a threaded groove, the threaded groove is rectangular in shape, and the thread pitch of the threaded groove is 2-5mm.

[0012] A further improvement to the above scheme is that both the transmission guide rail and the transmission lead screw are made of SKD11 or DC53 material, and the quenching hardness reaches 56-60HRC.

[0013] A further improvement to the above scheme is that the transmission control module includes a circulating water tank, a circulating water pump, and a water tank cooling element. The water tank cooling element is disposed on one side of the circulating water tank for cooling the circulating water tank. The circulating water pump is disposed inside the circulating water tank and is used to transport the liquid in the circulating water tank toward the first guide rail channel, and the second guide rail channel transports the liquid toward the circulating water tank.

[0014] A further improvement to the above scheme is that the first connecting element, the second connecting element, the third connecting element, the fourth connecting element, and the fifth connecting element are all transmission pipes. Each end of the transmission pipe is provided with a pipe interface. The transmission pipe includes a copper inner tube and an aluminum outer tube. The outer surface of the copper inner tube and the aluminum outer tube are metallurgically bonded together to form an integral unit. The outer surface of the aluminum outer tube is evenly distributed with grooves. The copper inner tube is used to transfer heat towards the aluminum outer tube, and the aluminum outer tube dissipates heat through the grooves.

[0015] A further improvement to the above solution is that the drive assembly includes a drive motor and a synchronous drive element. The drive motor is mounted on the base, and the synchronous drive element includes a synchronous belt, a first synchronous pulley, and a second synchronous pulley. The first synchronous pulley is mounted on the drive end of the drive motor, and the second synchronous pulley is mounted on one end of the transmission screw. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt. The outer diameter of the second synchronous pulley is larger than that of the first synchronous pulley.

[0016] A control method for a linear drive module includes a high-speed, high-temperature resistant linear drive module, wherein the control system includes a flow control module, a speed control module, an execution output module, and a temperature receiving module.

[0017] A further improvement to the above solution is that the base is provided with multiple transmission areas, each transmission area is provided with a transmission sensor, the transmission screw and the transmission guide rail drive the transmission seat to reciprocate between the multiple transmission areas, and the transmission seat is provided with a transmission sensing plate to cooperate with the transmission sensor.

[0018] A further improvement to the above scheme is that the control method of the linear transmission module is as follows: First, the driving liquid is transmitted sequentially through the first guide rail channel, the first lower channel, the second lower channel, the lead screw channel, the third lower channel and the second guide rail channel of the cooling circulation transmission module through the transmission control module. Then, the control system will start the drive component through the speed control module. The drive component drives the transmission lead screw to drive the transmission seat to slide along the transmission guide rail.

[0019] As the transmission seat slides along the transmission guide rail, it transmits power within a transmission area. As the sliding speed increases, the temperature sensing element on the transmission guide rail transmits temperature parameters to the temperature receiving module. The control system obtains flow rate control parameters based on the temperature parameters, and then sends these parameters to the cooling circulation transmission module via the flow control module to control the flow rate of the coolant within the module, ensuring the temperature parameters remain within a certain threshold. The speed control module increases the output speed of the drive assembly, thereby increasing the sliding speed of the transmission seat and the transmission guide rail, and raising the temperature generated by friction. At this time, based on the increased temperature, the flow control module increases the transmission speed of the transmission control module, increasing heat exchange efficiency. If the current transmission area exceeds the preset threshold for the set transmission speed, the drive assembly drives the transmission screw to switch the transmission seat to the next transmission area for transmission.

[0020] The beneficial effects of this invention are:

[0021] Compared to existing linear modules, the transmission assembly of this invention ensures high-speed and precise transmission. Two sets of transmission guide rails, respectively positioned on both sides of the base, and two sets of fixed end plates providing stable support at both ends of the base, provide a stable mounting foundation for the transmission screw. The sliding fit between the transmission seat and the transmission guide rails, along with the connection of the transmission screw, allows the module to slide smoothly and at high speed along the transmission guide rails under the drive of the drive assembly. This design not only improves the accuracy and stability of the transmission but also significantly enhances the module's working efficiency and load capacity. Secondly, the efficient operation of the drive assembly further enhances the module's transmission performance. The close cooperation between the drive assembly and the transmission screw ensures that the module can respond quickly upon receiving a drive signal, enabling rapid movement of the transmission seat. Simultaneously, the intelligent control of the drive assembly allows the module to adjust the transmission speed and force according to actual needs, thereby meeting the transmission requirements under various complex working conditions. However, in high-temperature environments, heat dissipation becomes a key factor limiting the module's performance. Therefore, the circulating heat dissipation assembly, through the coordinated work of the control system, the cooling circulation transmission module, and the transmission control module, effectively dissipates heat inside the module. The first guide rail channel, first lower channel, second lower channel, lead screw channel, third lower channel, and second guide rail channel in the cooling circulation transmission module together form a complete cooling circulation loop. This loop not only covers the main heat-generating components of the module, such as the transmission guide rail and transmission lead screw, but also ensures uniform distribution and efficient flow of coolant through a reasonable channel design. During the cooling cycle, the transmission control module is responsible for supplying coolant to the first guide rail channel, while the second guide rail channel is responsible for sending the returned coolant back to the transmission control module for recooling. This design not only improves cooling efficiency but also avoids coolant waste and contamination. Simultaneously, the ingeniously designed connecting elements between the channels ensure smooth coolant flow and prevent leakage problems caused by improper connections. In high-temperature environments, the introduction of the circulating heat dissipation component significantly improves the module's heat dissipation efficiency, ensuring the stability and reliability of the module under long-term, high-load operation.

[0022] The control method for the linear drive module achieves precise temperature control by introducing a flow control module and a cooling circulation transmission module. The coolant circulates in preset channels (including the first guide rail channel, first lower channel, second lower channel, lead screw channel, third lower channel, and second guide rail channel), effectively removing heat generated by high-speed transmission. Temperature sensors monitor the temperature changes of the drive rails in real time and feed the data back to the temperature receiving module. The control system dynamically adjusts the coolant flow rate accordingly, ensuring the module temperature remains within a safe and efficient range, effectively extending the module's lifespan. The speed control module intelligently adjusts the output speed of the drive component based on temperature parameters and preset flow rate control parameters, thereby dynamically adjusting the sliding speed of the transmission seat along the drive rails. This adaptive speed adjustment mechanism maximizes transmission efficiency while avoiding overheating caused by excessive speed, achieving dual optimization of speed and temperature.

[0023] In this embodiment, when the speed in the current transmission zone reaches or exceeds a preset threshold, the control system automatically instructs the drive component to switch the transmission seat to the next transmission zone to continue working. This mechanism not only ensures the stability of the module under continuous high-load operation, but also reduces wear in a single area by distributing the transmission load, thereby improving the durability and reliability of the entire system. The control system is highly integrated, with each module working collaboratively to achieve intelligent management of the entire chain, from temperature monitoring and flow control to speed regulation. This not only simplifies the operation process and reduces the need for manual intervention, but also significantly improves the system's response speed and accuracy, providing strong support for industrial automation and intelligent manufacturing. This embodiment, by flexibly adjusting control parameters, can adapt to different working environments and task requirements, demonstrating excellent performance in both stable operation under high-temperature environments and precise control under high-speed transmission. This adaptability makes this linear transmission module widely applicable in various industrial application scenarios. Attached Figure Description

[0037] like Figures 1-5As shown, in one embodiment of the present invention, a high-speed, high-temperature resistant linear transmission module is provided, including a transmission component 1, a drive component 2, and a circulating heat dissipation component 3. The transmission component 1 includes a base 11, a transmission guide rail 12, a transmission screw 13, a fixed end plate 14, and a transmission seat 15. There are two sets of transmission guide rails 12, which are respectively disposed on both sides of the base 11. There are two sets of fixed end plates 14, which are respectively disposed at both ends of the base 11. The two ends of the transmission screw 13 are mounted on the fixed end plate 14. The transmission seat 15 is disposed on the transmission guide rail 12 and connected to the transmission screw 13. The drive component 2 is disposed on the base 11 and is used to drive the transmission screw 13 to drive the transmission seat 15 to slide along the transmission guide rail 12. The circulating heat dissipation assembly 3 includes a control system 31, a cooling circulation transmission module 32, and a transmission control module 33. The control system 31 is electrically connected to the cooling circulation transmission module 32 and the drive assembly 2. The cooling circulation transmission module 32 includes a first guide rail channel 321, a first lower channel 322, a second lower channel 323, a lead screw channel 324, a third lower channel 325, and a second guide rail channel 326. The first guide rail channel 321 and the second guide rail channel 326 are respectively arranged on two sets of transmission guide rails 12 and pass through the length of the transmission guide rails 12. The first lower channel 322, the second lower channel 323, and the third channel all pass through the length of the base 11. The lead screw channel 324 passes through the length of the transmission lead screw 13. One end of the first guide rail channel 321 is connected to the transmission control module 33, and the other end is provided with a first connection. Component 34 is connected to the first downstream channel 322. A second connecting element 35 is provided at one end of the first downstream channel 322. One end of the second connecting element 35 is connected to the second downstream channel 323. A third connecting element 36 is provided in the second downstream channel 323 and is connected to one end of the lead screw channel 324. One end of the third connecting element 36 is rotatably connected to the lead screw channel 324. A fourth connecting element 37 is rotatably connected to one end of the lead screw channel 324. One end of the fourth connecting element 37 is connected to the third downstream channel 325. A fifth connecting element 38 is provided at one end of the third downstream channel 325 and is connected to the second guide rail channel 326. One end of the second guide rail channel 326 is connected to the transmission control module 33. The transmission control module 33 supplies liquid to the first guide rail channel 321, and the second guide rail channel 326 returns liquid to the transmission control module 33. In this embodiment, the transmission assembly 1 ensures high-speed and precise transmission of the module. Two sets of transmission guide rails 12 are respectively set on both sides of the base 11, and two sets of fixed end plates 14 provide stable support at both ends of the base 11, providing a stable mounting foundation for the transmission screw 13. The sliding fit between the transmission seat 15 and the transmission guide rails 12, as well as the connection of the transmission screw 13, enable the module to slide smoothly and at high speed along the transmission guide rails 12 under the drive of the drive component 2.This design not only improves the accuracy and stability of the transmission but also significantly enhances the module's working efficiency and load capacity. Secondly, the efficient operation of the drive assembly 2 further enhances the module's transmission performance. The close cooperation between the drive assembly 2 and the transmission screw 13 ensures that the module can respond quickly upon receiving a drive signal, enabling rapid movement of the transmission seat 15. Simultaneously, the intelligent control of the drive assembly 2 allows the module to adjust the transmission speed and force according to actual needs, thereby meeting the transmission requirements under various complex working conditions. However, in high-temperature environments, the module's heat dissipation becomes a key factor restricting its performance. Therefore, the circulating heat dissipation assembly 3, through the coordinated operation of the control system 31, the cooling circulation transmission module 32, and the transmission control module 33, effectively dissipates heat within the module. The first guide rail channel 321, the first lower channel 322, the second lower channel 323, the screw channel 324, the third lower channel 325, and the second guide rail channel 326 in the cooling circulation transmission module 32 together constitute a complete cooling circulation loop. This circuit not only covers the main heat-generating components of the module, such as the transmission guide rail 12 and the transmission lead screw 13, but also ensures uniform distribution and efficient flow of coolant through a reasonable flow channel design. During the cooling cycle, the transmission control module 33 is responsible for supplying coolant to the first guide rail flow channel 321, while the second guide rail flow channel 326 is responsible for sending the returned liquid back to the transmission control module 33 for recooling. This design not only improves cooling efficiency but also avoids waste and contamination of coolant. At the same time, the ingenious design of the connecting elements between the various flow channels ensures smooth flow of coolant while avoiding leakage problems caused by improper connections. In this embodiment, the introduction of the circulating heat dissipation component 3 significantly improves the module's heat dissipation efficiency in high-temperature environments, ensuring the stability and reliability of the module under long-term, high-load operation.

[0038] The base 11 is provided with multiple heat dissipation holes 111, which extend along the length of the base 11. Multiple sets of heat dissipation holes 111 are arranged, with two holes in each set. These multiple sets of heat dissipation holes 111 are respectively located on both sides of the first lower flow channel 322, the second lower flow channel 323, and the third lower flow channel 325 for heat dissipation. In this embodiment, the heat dissipation holes 111 extend along the length of the base 11, which not only optimizes the heat conduction path inside the module but also greatly improves heat dissipation efficiency. The heat dissipation holes 111 form a multiple-set layout, with each set containing two holes. This layout ensures that the heat from the lower flow channels can be dissipated evenly and quickly through the holes, avoiding performance degradation or damage to the module due to overheating. The multiple sets of heat dissipation holes 111 are respectively located on both sides of the first lower flow channel 322, the second lower flow channel 323, and the third lower flow channel 325. This design not only focuses on heat dissipation in key heat dissipation areas of the module but also forms a more efficient heat dissipation system through the cooperation of the flow channels and the holes. When the module is running at high speed, it can quickly dissipate the heat generated by friction, ensuring that the module is always in the best working condition.

[0039] The base 11 has mounting grooves 112 on both sides, and multiple mounting countersunk holes 113 on the mounting grooves 112. These countersunk holes 113 extend along the thickness direction of the base 11. One side of the transmission guide rail 12 is positioned on the mounting groove 112, and mounting screws are provided on the mounting countersunk holes 113 to secure the transmission guide rail 12 to the mounting groove 112. The base 11 also has multiple fixing countersunk holes 114 for fixed installation. In this embodiment, the mounting grooves 112 on both sides of the base 11 not only optimize the structural layout of the module but also provide a solid foundation for the precise positioning and installation of the transmission guide rail 12. The multiple mounting countersunk holes 113 on the mounting grooves 112 are cleverly designed; these countersunk holes extend completely along the thickness direction of the base 11, ensuring that the mounting screws can penetrate deeply, thereby firmly locking the transmission guide rail 12 within the mounting grooves 112, greatly improving the stability and reliability of the module during operation. Furthermore, the engagement of the mounting countersunk holes 113 and the mounting screws ensures excellent mechanical transmission, guaranteeing that the transmission guide rail 12 maintains precise guiding and transmission performance even under extreme conditions such as high speed and high temperature. Simultaneously, the multiple fixing countersunk holes 114 added to the base 11 further enhance the overall stability of the module. These fixing countersunk holes 114 facilitate connection with external mounting structures, allowing the module to be securely installed on various equipment or platforms, effectively preventing displacement or loosening due to vibration or impact, and ensuring stable operation of the module in various complex environments.

[0040] The transmission guide rail 12 includes a guide rail body 121 and a guide rail slider 122. The guide rail slider 122 is slidably mounted on the guide rail body 121. Guide rail grooves 1211 are provided on both sides of the guide rail body 121. A heat dissipation surface 1212 is provided on the upper surface of the guide rail body 121. A heat dissipation gap is provided between the guide rail slider 122 and the heat dissipation surface 1212. A heat dissipation groove 1213 is provided on the heat dissipation surface 1212 to dissipate heat from the guide rail grooves 1211. A first guide rail flow channel 321 is located near the heat dissipation surface 1212 and the guide rail grooves 1211. The guide rail slider 122 is provided with a sliding engagement part 1221, which is disposed on the guide rail grooves 1211. In this embodiment, the precise sliding engagement design of the guide rail body 121 and the guide rail slider 122 ensures the stability and reliability of the module under high-speed operation. The carefully designed guide rail grooves 1211 on both sides of the guide rail body 121 not only provide a smooth sliding path for the guide rail slider 122, but also effectively improve the overall guiding accuracy of the module. The heat dissipation surface 1212 and its heat dissipation grooves 1213 on the upper surface of the guide rail body 121 are a major highlight of this structure. The heat dissipation gap effectively isolates the heat conduction between the guide rail slider 122 and the heat dissipation surface 1212, reducing the impact of heat generated by friction on module performance. The heat dissipation grooves 1213, by increasing the area of ​​the heat dissipation surface 1212, accelerate heat dissipation, significantly improving the module's working stability and service life in high-temperature environments. Furthermore, the layout of the first guide rail flow channel 321 close to the heat dissipation surface 1212 and the guide rail grooves 1211 further optimizes the heat conduction path inside the module, allowing heat to be discharged more efficiently through the cooling system, thereby maintaining a balanced internal temperature within the module.

[0041] A temperature sensing element 1222 is provided on the guide rail slider 122, and a connecting slot is provided on the guide rail slider 122. One end of the temperature sensing element 1222 is inserted into the connecting slot and close to the guide rail groove 1211. The temperature sensing element 1222 is used to sense the temperature generated by high-speed friction between the guide rail slider 122 and the guide rail groove 1211. The control system 31 is electrically connected to the temperature sensing element 1222 and receives the temperature parameters sensed by the temperature sensing element 1222. The control system 31 controls the transmission speed of the transmission control module 33 according to the temperature parameters. In this embodiment, the temperature sensing element 1222 achieves real-time monitoring of frictional heat by accurately sensing the temperature generated by high-speed friction between the guide rail slider 122 and the guide rail groove 1211. This design not only improves the safety of the module during operation, but also helps to detect and prevent potential failures caused by overheating in a timely manner, thereby extending the service life of the module. Secondly, the tight fit between the temperature sensing element 1222 and the connecting slot ensures the accurate transmission of temperature signals. This design simplifies the structure of the temperature monitoring system and improves its reliability and stability. Meanwhile, the convenient connection slots greatly facilitate subsequent maintenance and upgrades. Finally, the control system 31 intelligently adjusts the transmission speed of the transmission control module 33 based on the temperature parameters provided by the temperature sensing element 1222. This function enables the module to maintain optimal operating conditions under different operating conditions, improving work efficiency and reducing energy consumption. Furthermore, intelligent speed control helps reduce vibration and noise during high-speed operation, enhancing overall operational quality.

[0042] The fixed end plate 14 is provided with a rotating fixing hole 141, and a rotating bearing 142 is provided on the rotating fixing hole 141. The transmission screw 13 is mounted on the rotating bearing 142. The transmission seat 15 is provided with a screw nut 151. The transmission seat 15 is threadedly connected to the transmission screw 13 through the screw nut 151. The transmission screw 13 is provided with a threaded groove 131. The threaded groove 131 is rectangular in shape, and the pitch of the threaded groove 131 is 2-5 mm. A further improvement to the above scheme is that both the transmission guide rail 12 and the transmission screw 13 are made of SKD11 or DC53 material, and the quenching hardness reaches 56-60 HRC. In this embodiment, the rotating fixing hole 141 and the rotating bearing 142 provided on the fixed end plate 14 not only ensure the stable rotation of the transmission screw 13, but also greatly reduce friction loss and improve transmission efficiency. The transmission seat 15 is threadedly connected to the transmission screw 13, which has a rectangular threaded groove 131, via a screw nut 151. This design not only enhances the stability of the connection but also effectively prevents loosening or stripping of the threads during high-speed operation due to the special shape of the rectangular threaded groove 131. Furthermore, the transmission guide rail 12 and the transmission screw 13 are made of high-quality materials such as SKD11 or DC53. These materials possess excellent wear resistance and high-temperature stability, ensuring stable operation of the module under long-term, high-load, and high-temperature environments. Simultaneously, quenching treatment brings the material hardness to 56–60 HRC, further improving its wear resistance and deformation resistance, and extending the module's service life.

[0043] The transmission control module 33 includes a circulating water tank 331, a circulating water pump 332, and a water tank cooling element 333. The water tank cooling element 333 is located on one side of the circulating water tank 331 for cooling the circulating water tank 331. The circulating water pump 332 is located inside the circulating water tank 331 and is used to transport the liquid in the circulating water tank 331 toward the first guide rail channel 321, and the second guide rail channel 326 transports the liquid toward the circulating water tank 331. In this embodiment, the circulating water tank 331 serves as a medium for heat collection and storage, capable of accommodating and buffering the heat generated during module operation. The water tank cooling element 333 effectively reduces the liquid temperature in the circulating water tank 331 through active cooling methods, such as heat exchange or refrigeration cycle, ensuring stable operation of the module in high-temperature environments. The integration of the circulating water pump 332 further improves the efficiency of the heat dissipation system. Located inside the circulating water tank 331, it efficiently transports the cooling liquid to the first guide rail channel 321 through precise control. This design not only accelerates heat conduction and dissipation but also achieves continuous cooling of the module's guide rails and transmission components through liquid circulation, ensuring the module's high-speed and high-precision operation. Simultaneously, the second guide rail flow channel 326 forms a complete liquid circulation loop. It is responsible for returning the liquid, after being cooled by the guide rails, to the circulating water tank 331 for the next cooling cycle. This circulation mechanism not only improves heat dissipation efficiency but also ensures the module's stable performance and reliability under long-term, high-intensity operation.

Each transmission pipe 39 has a pipe interface at both ends. The transmission pipe 39 includes a copper inner tube 391 and an aluminum outer tube 392. The copper inner tube 391 and the aluminum outer tube 392 are metallurgically bonded together. The aluminum outer tube 392 has evenly distributed grooves 393 on its exterior. The copper inner tube 391 transfers heat towards the aluminum outer tube 392, and the aluminum outer tube 392 dissipates heat through the grooves 393. In this embodiment, the design of the transmission pipe 39 integrates the advantages of the copper inner tube 391 and the aluminum outer tube 392. Through metallurgical bonding technology, a high degree of integration between the two is ensured, thereby significantly improving the stability and durability of the overall structure. Due to its excellent thermal conductivity, the copper inner tube 391 can efficiently conduct the heat generated during module operation to the aluminum outer tube 392. The aluminum outer tube 392, with its excellent heat dissipation characteristics and evenly distributed external grooves 393, further enhances heat dissipation efficiency. This effective conduction and rapid dissipation of heat is crucial for maintaining stable operation of the module in high-temperature environments, effectively preventing performance degradation or failure due to overheating. Furthermore, the structural design of the transmission pipe 39 also considers the reliability and durability requirements of the connecting components for high-speed linear drive modules. The metallurgically combined copper inner tube 391 and aluminum outer tube 392 not only improve connection strength but also extend service life and reduce maintenance costs.

[0045] The drive assembly 2 includes a drive motor 21 and a synchronous drive element 22. The drive motor 21 is mounted on the base 11. The synchronous drive element 22 includes a synchronous belt 221, a first synchronous pulley 222, and a second synchronous pulley 223. The first synchronous pulley 222 is located at the drive end of the drive motor 21, and the second synchronous pulley 223 is located at one end of the transmission screw 13. The first synchronous pulley 222 and the second synchronous pulley 223 are connected by the synchronous belt 221. The outer diameter of the second synchronous pulley 223 is larger than that of the first synchronous pulley 222. In this embodiment, the drive motor 21 is securely mounted on the base 11, providing a strong and precise power source for the entire transmission system. The first synchronous pulley 222 is directly connected to the drive end of the drive motor 21, ensuring the directness and efficiency of power transmission and reducing energy loss. The synchronous belt 221, as a transmission medium, has high wear resistance, high elasticity, and low noise characteristics, and can maintain a stable transmission ratio under high-speed operation, effectively avoiding transmission errors caused by slippage or slack. The ingenious design between the first synchronous pulley 222 and the second synchronous pulley 223, especially the fact that the outer diameter of the second synchronous pulley 223 is larger than that of the first synchronous pulley 222, achieves the effect of speed reduction and torque increase, so that the transmission screw 13 can obtain greater torque when receiving power, thereby improving the smoothness of the module's operation and load-bearing capacity under load.

[0046] A control method for a linear drive module includes a high-speed, high-temperature resistant linear drive module. The control system 31 includes a flow control module 311, a speed control module 312, an execution output module 313, and a temperature receiving module 314. The base 11 is provided with multiple transmission areas, each of which is equipped with a transmission sensor 115. The transmission screw 13 and the transmission guide rail 12 drive the transmission seat 15 to reciprocate between the multiple transmission areas. The transmission seat 15 is provided with a transmission sensing plate 152 to cooperate with the transmission sensor 115. The control method of the linear transmission module is as follows: the transmission control module 33 transmits the driving liquid sequentially through the first guide rail channel 321, the first lower channel 322, the second lower channel 323, the screw channel 324, the third lower channel 325, and the second guide rail channel 326 of the cooling circulation transmission module 32. Then, the control system 31 starts the drive component 2 through the speed control module 312. The drive component 2 drives the transmission screw 13 to drive the transmission seat 15 to slide along the transmission guide rail 12. When the transmission seat 15 slides along the transmission guide rail 12, it transmits within one transmission area. The speed of sliding is adjusted according to the speed of the transmission. As the temperature increases, the temperature sensing element 1222 on the transmission guide rail 12 transmits the temperature parameters to the temperature receiving module 314. The control system 31 obtains the flow rate control parameters based on the temperature parameters, and then sends the flow rate control parameters to the cooling circulation transmission module 311 through the flow control module 311 to control the flow rate of the coolant in the cooling circulation transmission module 32, so that the temperature parameters are kept within a certain threshold. The speed control module 312 controls the output speed of the drive component 2 to increase, thereby increasing the sliding speed of the transmission seat 15 and the transmission guide rail 12, and increasing the temperature generated by friction. At this time, the temperature sensing element 1222 increases the transmission speed of the transmission control module 33 based on the increased temperature, thereby increasing the heat exchange efficiency. If the current transmission area exceeds the preset value of the set transmission speed threshold, the drive component 2 drives the transmission screw 13 to drive the transmission seat 15 to switch to the next transmission area for transmission.

[0047] This embodiment achieves precise temperature control of the transmission module by introducing a flow control module 311 and a cooling circulation transmission module 32. The coolant circulates in preset channels (including the first guide rail channel 321, the first lower channel 322, the second lower channel 323, the lead screw channel 324, the third lower channel 325, and the second guide rail channel 326), effectively removing heat generated by high-speed transmission. The temperature sensing element 1222 monitors the temperature change of the transmission guide rail 12 in real time and feeds the data back to the temperature receiving module 314. The control system 31 dynamically adjusts the coolant flow rate accordingly, ensuring that the module temperature is maintained within a safe and efficient range, effectively extending the module's service life. The speed control module 312 intelligently adjusts the output speed of the drive component 2 based on temperature parameters and preset flow rate control parameters, thereby dynamically adjusting the sliding speed of the transmission seat 15 along the transmission guide rail 12. This adaptive speed adjustment mechanism maximizes transmission efficiency while avoiding overheating caused by excessive speed, achieving dual optimization of speed and temperature.

[0048] In this embodiment, when the speed in the current transmission area reaches or exceeds a preset threshold, the control system 31 automatically instructs the drive component 2 to switch the transmission seat 15 to the next transmission area to continue working. This mechanism not only ensures the stability of the module under continuous high-load operation, but also reduces wear in a single area by distributing the transmission load, thereby improving the durability and reliability of the entire system. The control system 31 is highly integrated, with each module working collaboratively to achieve intelligent management of the entire chain from temperature monitoring and flow control to speed regulation. This not only simplifies the operation process and reduces the need for manual intervention, but also significantly improves the system's response speed and accuracy, providing strong support for industrial automation and intelligent manufacturing. This embodiment, by flexibly adjusting control parameters, can adapt to different working environments and task requirements, demonstrating excellent performance in both stable operation under high-temperature environments and precise control under high-speed transmission. This adaptability makes the linear drive module widely applicable in various industrial application scenarios.
