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 work shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-5 , the present utility model provides a technical solution: a linear motor module with buffering and anti-collision functions, including a base 1, a track 2, a stator 3, a slide rail 4, a supporting platform 5, a mover 6, a wiring port 701, a wiring port 702, a support block 8, a cylinder 9, a piston 10, a push rod 11, a buffer block 12, a spring 13, a gasket 14, and a support plate 15.

[0030] The cross-section of the base 1 is C-shaped. Two tracks 2 are symmetrically arranged on the upper surface of the base 1. The stator 3 is fixedly arranged in the groove on the upper surface of the C-shaped base 1. The outer surface of the track 2 is slidably connected with a slide rail 4. Two slide rails 4 are symmetrically arranged. The upper surface of the two slide rails 4 is fixedly installed with a supporting platform 5.

The wiring port 702 is connected to the mover 6;

[0031] As Figure 1 and Figure 5 shown, when using this device, connect the wiring port 701 and the wiring port 702 to the power supply respectively, turn on the power supply. Under the action of electricity and the stator 3, the stator 3 will slide reciprocally, and the stator 3 drives the upper supporting platform 5 to move. When the supporting platform 5 slides, the slide rail 4 on the lower surface of the supporting platform 5 contacts the track 2.

[0032] The cross-section of the track 2 is mainly a concave-shaped structure, and direction grooves are arranged on both sides of the track 2. The slide rail 4 is a structure that engages with the track 2. The gasket 14 is fixedly arranged on the surface of the track 2. The gasket 14 contacts the lower surface of the slide rail 4. A supporting structure is arranged on the surface of the support block 8. The sliding support plate 15 in the supporting structure increases the stability of the device. The supporting structure includes a support plate 15. The support plate 15 is a long strip structure, and the support plate 15 is slidably installed on the side surface of the support block 8. And support plates 15 are respectively arranged on both sides of the support plate 15. Multiple threaded mounting holes are arranged on the surface of the support plate 15;

[0033] As Figure 1 and Figure 2 shown, when the supporting platform 5 slides, the slide rail 4 slides on the upper surface of the track 2. Multiple grooves are arranged on the surface of the track 2, and the grooves on the surface of the track 2 respectively engage with the surface of the slide rail 4, so that when the slide rail 4 slides, it will not derail. The gasket 14 can reduce the wear between the slide rail 4 and the track 2 and increase the service life. Pull out the support plates 15 on both sides of the support block 8 outward, which can increase the support area of the support block 8, thereby increasing the stability of the device.

[0034] Buffer structures are provided on both sides of the base 1. The buffer structures are provided with a piston 10 and a push rod 11 to achieve the buffering effect on the supporting platform 5. The buffer structure includes support blocks 8. There are 2 support blocks 8 symmetrically arranged. The 2 support blocks 8 are respectively fixedly connected to the two side surfaces of the base 1. The support blocks 8 cover the side surface of the slide rail 4. A cylinder 9 is embedded in the inner wall of the support block 8. The inside of the cylinder 9 is hollow, and a piston 10 is slidably arranged on the inner wall of the cylinder 9.

[0035] As Figure 1 , Figure 3 and Figure 4 shown, when the supporting platform 5 slides to both ends of the device on the surface of the device, the supporting platform 5 pushes the buffer block 12 to one side. The buffer block 12 drives the push rod 11 to move. The push rod 11 drives the piston 10 to slide on the inner wall of the cylinder 9. During the process of the piston 10 sliding on the inner wall of the cylinder 9, the air inside the cylinder 9 will be compressed. The air can be used to buffer the piston 10. At the same time, the movement of the piston 10 will drive the spring 13 to be compressed. The piston 10 and the spring 13 can be used together to effectively buffer the supporting platform 5. And the spring 13 is located inside the cylinder 9 to prevent the spring 13 from being corroded by the air.

[0036] Working principle: When using this buffer and anti-collision linear motor module, the support plate 15 sliding on the surface of the support block 8 can increase the support area of the device, and threaded mounting holes are provided on the surface of the support plate 15, which is convenient for the device to be threadedly connected to the working plane. Using the three-sided groove track 2 and the slide rail 4

[0037] to engage, it can prevent the supporting platform 5 from derailing on the surface of the track 2.
