[0014] 1. An air duct, a fan and a fixed motor are provided. When the linear moving module moves for a long time, a large amount of heat will be generated. In order to ensure the service life of the guide rail slider, the fixed motor is started to drive the fan to rotate, so that the fan blows air into the inside of the guide rail slider through the air duct. To ensure the air circulation inside the guide rail slider, the internal heat is discharged outwards through the lower end of the air duct, which is convenient for dissipating heat from the linear motor module and maintaining the service life of the linear transplanting;

[0015] 2. A filter screen, a second bolt and a nut are provided. Since the guide rail slider is used for a long time and the internal heat dissipation device is also operating continuously, a large amount of dust accumulates on the surface of the filter screen.

[0016] 3. A fixed rod, an aggregate box and steel balls are provided. When the guide rail slider moves on the track for a long time, the sliding speed of the guide rail slider decreases. In order to ensure the normal movement of the guide rail slider, lubricant needs to be added into the interior of the aggregate box through the feeding port at the upper right end of the guide rail slider. When the guide rail slider slides on the fixed rod, the guide rail slider drives the steel balls to rotate on the fixed rod. At the same time, the lubricating liquid is adsorbed on the upper end of the steel balls, and the steel balls bring the lubricating liquid inside the aggregate box to the upper end of the fixed rod when rotating, so that the surface of the fixed rod is in a lubricated state, which is convenient for realizing the automatic lubrication efficiency of the linear motor module.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer toFigures 1-5 , the present utility model provides a technical solution: a linear motor module with overheat prevention and self-lubrication, including a protective shell 1, a stator 2, a guide rail slider 3, a mounting bracket 4, a first bolt 5, a ventilation pipe 6, a fan 7, a fixed motor 8, a filter screen 9, a second bolt 10, a nut 11, a fixed rod 12, an aggregate box 13, a first spring 14, steel balls 15, a second spring 16, and a mounting plate 17.

[0025] When internal heat dissipation is carried out for the linear motor module, as Figure 2 and Figure 5 shown, the outer end of the stator 2 is fixedly connected to the lower end inside the guide rail slider 3, and the upper end of the guide rail slider 3 is provided with a mounting bracket 4 and a first bolt 5, and the first bolt 5 is installed in the middle of the mounting bracket 4. The inside of the guide rail slider 3 is provided with a ventilation pipe 6 and an aggregate box 13, and the aggregate box 13 is located on the front and back sides of the ventilation pipe 6. The upper end inside the ventilation pipe 6 is installed with a fan 7, and the upper end of the fan 7 is installed and connected with a fixed motor 8. The lower end of the ventilation pipe 6 is installed with a filter screen 9, and the front and back ends of the filter screen 9 are connected with a second bolt 10, and the lower end of the second bolt 10 is installed with a nut 11. First, the guide rail slider 3 is installed on the stator 2, and then the mounting plate 17 is installed on the right side of the protective shell 1 to ensure the movement track of the guide rail slider 3 inside the protective shell 1. When the guide rail slider 3 reciprocates on the upper end of the stator 2 for a long time, a large amount of heat is generated inside the guide rail slider 3. To ensure the service life of the guide rail slider 3, the fixed motor 8 is started to drive the fan 7 to rotate, and the fan 7 blows air inside the ventilation pipe 6 to help cool the whole guide rail slider 3. To ensure air circulation, the internal heat is discharged through the lower end of the ventilation pipe 6. Since a large amount of dust will remain on the surface of the filter screen 9 after long-term heat dissipation, at this time, the fixed rod 12 at the lower end of the nut 11 is removed, and the filter screen 9 can be removed and replaced from the lower end of the ventilation pipe 6. Through such operations, effective heat dissipation inside can be helped;

[0026] When using the linear motor module with overheat prevention and self-lubrication, as Figure 1 and Figure 4, a first spring 14 and a steel ball 15 are installed at the lower end of the aggregate box 13, and the steel ball 15 is located at the lower end of the first spring 14, and a fixing rod 12 is provided at the lower end of the steel ball 15. A second spring 16 is connected to the right side of the guide rail slider 3. To ensure the movement efficiency of the guide rail slider 3, first, a large amount of lubricant is added to the aggregate box 13 inside the guide rail slider 3 through the upper feeding port on the right side of the guide rail slider 3. When the guide rail slider 3 moves, it will slide along the trajectory of the fixing rod 12. At this time, the upper end of the fixing rod 12 is in contact with the lower end of the steel ball 15. During the rolling process of the steel ball 15, the lubricant inside the aggregate box 13 is smeared on the surface of the fixing rod 12, which can assist the effective movement of the guide rail slider 3. At the same time, the guide rail slider 3 moves left and right. To avoid hitting the inner wall of the protective shell 1 at too high a speed, the impact speed of the guide rail slider 3 is reduced by the second spring 16. This is the usage method of the anti-overheating self-lubricating linear motor module.
