Furthermore, linear motion modules are characterized by their compact structure, easy installation, and low maintenance costs. They can flexibly adapt to different working environments and task requirements, making them an indispensable key component in modern intelligent manufacturing.

[0003] However, during operation, the mobile module generates a lot of heat due to frequent motor starts and stops, high-speed movement, and load. Excessive temperature will affect the working efficiency of the motor and other electronic components, leading to reduced speed and accuracy, and in severe cases, damage to the motor and affecting the service life of the linear motor. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please refer to Figure 1-7 ;

[0026] A heat dissipation structure for a multi-axis moving module is provided to solve the heat dissipation problem of the moving module under high-precision and high-speed motion, and to ensure long-term stable operation of the equipment.

[0027] Specifically, the device includes a magnetic yoke 1, with a groove 2 on the yoke 1. A stator 3 is symmetrically arranged on the inner wall of the groove 2. A mover 4 is slidably connected between the two stators 3. A base 5 is located on the other side of the magnetic yoke 1. A moving guide rail 51 is mounted on the base 5. A moving slider 52 is slidably connected to the moving guide rail 51. A support 6 is mounted on the mover 4 and the moving slider 52, supporting both ends of the support 6 to ensure its stability. A bracket 61 is mounted on the support 6. A stator 62 is vertically and symmetrically mounted on the bracket 61. A mover 63 is mounted between the two stators 62, located on one side of one of the stators 62. A moving guide rail 64, fixedly connected to the bracket 61, is vertically mounted on the moving guide rail 64. A moving slider 65 is slidably connected to the moving guide rail 64. A mounting platform 66 is mounted on the moving slider 65 and the stator 62. The mounting platform 66 is used to mount other working devices, enabling the device to perform multi-axis movement and increasing efficiency. For flexibility, since the stator and mover generate a lot of heat during operation, both stator 3 and stator 62 in this embodiment are provided with several through holes 31 extending through both ends. Each through hole 31 is equipped with a vent pipe 32 to promote air circulation, help dissipate heat, and reduce the stator temperature. At the same time, a fan corresponding to the vent pipe 32 can be set externally to accelerate the air flow speed in the vent pipe 32, further improving the heat dissipation efficiency and ensuring that the stator is maintained at a low operating temperature. At least one air intake hole 11 is symmetrically provided at both ends of the bottom of the magnetic yoke 1. At least one air intake device is provided at the lower end of each air intake hole 11. The function of the air intake device is to draw out the airflow passing between stator 3 and mover 4 and discharge it through the air intake hole 11. Since the air intake holes 11 are distributed at both ends of the magnetic yoke 1, it is ensured that the airflow can flow through all areas of the magnetic yoke 1, effectively improving the overall heat dissipation performance of the moving module and preventing the problem of local overheating.

[0028] To ensure smooth operation of the moving parts, an oil injection pump 67 is installed on the support base 6, and an oil inlet pump 511 is installed on both the first moving slider 52 and the second moving slider 65. The connection between the oil injection pump 67 and the external oil storage device and the two oil inlet pumps 511 evenly distributes the lubricating oil to the oil inlet pumps 511 on the first moving slider 52 and the second moving slider 65. Both the first moving slider 52 and the second moving slider 65 are equipped with identical oil delivery structures, which are connected to the corresponding oil inlet pumps 511. Through their respective oil delivery structures, the lubricating oil is accurately delivered to the surface of the moving guide rail, achieving effective lubrication, reducing friction between the moving slider and the guide rail, and extending the service life of the equipment.

[0029] Specifically, the external oil storage device injects lubricating oil into the oil pump 67. Through the diversion mechanism of the oil pump 67, the lubricating oil is evenly distributed to the oil inlet pumps 511 on the first movable slider 52 and the second movable slider 65. After receiving the lubricating oil from the oil pump 67, each oil inlet pump 511 will guide it directly to the surface of the movable guide rail that it contacts through the oil delivery structure on the movable slider. This allows the lubricating oil to flow to the movable guide rail, achieving a good lubrication effect, reducing friction between the movable slider and the guide rail, and extending the service life of the equipment.

[0030] Two schemes are available for the oil transportation structure;

[0031] Option 1: The oil delivery structure includes an oil delivery channel 522 set in the first movable slider 52 and the second movable slider 65. The oil delivery channel 522 is connected to the movable guide rail. The oil pump 511 is used to directly deliver lubricating oil to the movable guide rail to achieve the purpose of lubrication.

[0032] Option 2: The oil supply structure includes several interconnected oil supply holes 523 on the first movable slider 52 and the second movable slider 65. The oil supply holes 523 serve as channels for the transmission of lubricating oil. Each of the oil supply holes 523 contains a ball bearing 524 that contacts the corresponding movable guide rail. The ball bearing 524 is responsible for evenly applying the lubricating oil to the surface of the guide rail. A sleeve 525 is provided on the ball bearing 524. The sleeve 525 has a hollow center to allow the lubricating oil to pass through. A circular groove 526 is provided at the end of the sleeve 525 away from the ball bearing 524. A spring 527 is placed on the circular groove 526. The other end of the spring 527 abuts against a cap 528. The pressure of the spring 527 ensures good contact between the ball bearing 524 and the movable guide rail. The oil cap 528 is threadedly connected to the oil supply hole 523 to provide a seal and prevent lubricating oil leakage.

[0033] Specifically, the oil pump 511 injects lubricating oil into the oil supply hole 523. The lubricating oil flows through the central hole of the sleeve 525 to the surface of the ball 524. As the moving slider moves along the guide rail, the ball 524 rotates accordingly, spreading the lubricating oil evenly on the guide rail surface to form a protective layer and reduce frictional resistance. In addition, when the ball 524 encounters unevenness or impurities on the guide rail, the spring 527 can be appropriately compressed, causing the ball 524 to temporarily retract into the oil supply hole 523 to avoid hard collision with the obstacle and damage. Once the ball 524 passes the obstacle, the spring 527 returns to its original position, pushing the ball 524 to press against the guide rail surface again, ensuring that the lubrication process is not affected.

[0034] To prevent the ball 524 from coming out of the oil inlet 523, and to allow the ball 524 to move freely in the hole to adapt to changes in the guide rail surface, the diameter of the oil inlet 523 corresponding to the moving guide rail is designed to be smaller than that of the ball 524.

[0035] In this embodiment, a third mover 7 with the same structure as the first mover 4 is also provided between the two stators 3. The parts installed on the third mover 7 are the same as those on the first mover 4. The first mover 4 and the third mover 7 are respectively located at both ends of the stator 3. They can achieve independent linear motion in the axial direction through an independent drive system, which enhances the flexibility and multifunctionality of the system.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
