Description

Technical Field

[0001] This invention relates to a highly stable linear motor device. Background Technology

[0002] Currently, laser processing is an advanced manufacturing technology that uses laser beams to perform various processing operations on materials, such as cutting, engraving, and drilling. Laser processing has advantages such as non-contact, high precision, and high speed, and can be applied to the processing of a variety of materials, such as metals, ceramics, plastics, and paper. During the laser processing process, a linear motor is required to control the movement of the laser beam on a plane.

[0003] Chinese patent application number 202123136600.5 discloses a highly stable linear motor, which sets the ball bearings and limiting grooves on the two outer end faces of the module base, reducing the difficulty of assembly and making disassembly more convenient than before.

[0004] However, during the operation of the linear motor, the side plate has a gap for the moving part to slide. During use, cutting debris and external particles can easily enter the interior of the linear motor through the gap, interfering with the use of the device and affecting its stability. In addition, due to the uncertainty of the operating environment and the large amount of heat generated by the coil inside the moving part, the heat dissipation effect inside the device is poor, affecting the reliability of use. Summary of the Invention

[0025] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this invention, directional and ordinal terms are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-4As shown, a high-stability linear motor device includes a base 1 and a fan assembly 8. A stator 2 is installed in the middle of the base 1, and guide rails 3 are arranged parallel to each other on both sides of the stator 2. Side plates 4 are fixed at both ends of the base 1. A mover seat 5 is slidably arranged on the guide rails 3, and a mover 6 is installed at the bottom of the mover seat 5. A top cover 7 is erected between the two side plates. The top cover 7 is located on the mover seat 5 and radiates the movement range of the mover seat 5. A fan assembly 8 is installed on the outer side of each side plate 4. Two rows of air guide pipes 9 are arranged on the top of the top cover 7. Multiple nozzles 10 are evenly installed on the air guide pipes 9, and the nozzles 10 all face the outside of the top cover 7. The fan assembly 8 includes a mounting chamber 12, a cooling fan 13, and an air shroud 14. The mounting chamber 12 is fixed on the side plate 4. The cooling fan 13 is installed in the mounting chamber 12. The air shroud 14 is installed at the end of the mounting chamber 12 away from the side plate 4. The input end of the air guide pipe 9 is inserted into the air shroud 14. A crash block is fixed to the inside of the side panel 4, and a rubber block is provided on the crash block.

[0027] During laser processing, the laser head mounting bracket is fixed on the moving base 5. The laser head is moved on the horizontal plane by a linear motor. At the same time, the fan assembly 8 is turned on, and the gas is discharged from the nozzle 10 through the air guide pipe 9, forming an air curtain on the outside of the top cover 7 to block the flying debris and isolate impurities.

[0028] Air grooves 11 are provided on both sides of the inside of the moving base 5. One end of the air groove 11 is located inside the moving base 5, facing the nozzle, and the other end of the air groove 11 is located at the bottom of the outside of the moving base 5. When the moving base 5 slides linearly, it partially blocks the nozzle 10. At this time, the gas discharged from the nozzle 10 enters the interior of the air groove 11 and then exits from the other end of the air groove 11, carrying away the heat generated by the coil inside the moving base 6 and achieving cooling.

[0029] A through slot is provided on the side plate 4, facing the input end of the cooling fan 13. The cooling fan 13 accelerates the airflow rate inside the device, improving the heat dissipation effect.

[0030] A slot 16 is provided on the top of the mounting chamber 12 near the side plate 4, and a filter 17 is inserted into the slot 16. The cooling fan 13 generates negative pressure inside the mounting chamber 12, which can draw dust from inside the device into the mounting chamber 12, and filter the dust using the filter 17 to ensure the cleanliness of the interior.

[0031] A thermoelectric cooler 18 is mounted on the top of the mounting chamber 12, with the cooling end of the thermoelectric cooler 18 attached to the mounting chamber 12. The thermoelectric cooler 18 is used for cooling, improving the temperature reduction effect during use.

[0032] In summary, this invention features a novel design and simple structure. The fan assembly is mounted on the side plate, and combined with the air duct and nozzle on the top cover, an air curtain is formed on both sides of the device during use. This effectively prevents debris and particulate impurities from entering, avoids dust from entering the device's interior, and ensures stability during movement.

[0033] An air groove is provided inside the mover base, with one end of the air groove facing the nozzle and the other end located on the outside. This allows the gas discharged from the nozzle to enter the air groove during the movement of the mover base, accelerating the heat dissipation from the coil inside the mover.

[0034] A through slot is opened on the side plate to connect the air inlet of the fan assembly to the inside of the device. Then, the filter screen inside the mounting slot is used to filter and clean the dust inside the device during use, resulting in better dust removal and improved reliability of the device.

[0035] The top of the installation compartment is equipped with a semiconductor cooling chip, which has excellent cooling effect and high applicability.
