second pulleys

533 and 535. When the transmission assembly 55 drives the carriage 531 to move, the second pulley 535 can roll along the second optical axis 515. Since the second pulley 535 is capable of rolling along the second optical axis 515, i.e., the second pulley 535 is in rolling connection with the second optical axis 515, it is advantageous to reduce friction between the second pulley 535 and the second optical axis 515.

In this embodiment, an annular sliding groove 5351 is disposed on an outer wall of the second pulley 535, the second optical axis 515 passes through the sliding groove 5351, and the second optical axis 515 is slidably connected to the sliding groove 5351 of the second pulley 535.

The first optical axis 513 and the second optical axis 515 guide the movement of the bearing seat 531 along the second direction, so that the smoothness and the movement precision of the linear movement of the bearing seat 531 along the second direction are improved, the noise is reduced, the abrasion between the bearing component 53 and the guide rail frame 511 is reduced, and the laser processing equipment 1000 has the characteristics of high precision, high strength, long service life and low noise.

In addition, the bearing plate 5311 covers the guide groove 5115, the first pulley 533 is located between the bearing plate 5311 and the guide rail frame 511, and the second pulley 535 is located on a side of the guide rail portion 5113 away from the first optical axis 513, so that the first pulley 533 is hidden in the guide groove 5115, and the second pulley 535 is hidden under the guide rail frame 511, which is beneficial to reducing interference of other elements on movement of the first pulley 533 and the second pulley 535, and is also beneficial to miniaturization development of the guide rail apparatus 50.

The driving member 54 is fixed to the rail frame 511 and disposed near one end of the guide groove 5115. The driving shaft of the driving member 54 is connected with the transmission assembly 55 for driving the transmission assembly 55 to move.

In this embodiment, the driving member 54 is a rotating motor, the driving member 54 drives the driving wheel 551 to rotate, and the driving wheel 551 drives the timing belt 555. When the driving member 54 drives the driving wheel 551 to rotate, the driving wheel 551 drives the synchronous belt 555 to move, so as to drive the carrying assembly 53 to move linearly along the first optical axis 513 and the second optical axis 515.

It is understood that the connecting member 5312 can be omitted and the carrier plate 5311 can be directly connected to the timing belt 555.

The rail device 50 is linearly moved in the first direction on the rail device 30. In this way, the machining position of the laser device 70 is changed by the movement of the rail device 50 on the rail device 30 and the movement of the laser device 70 on the rail device 50.
