Description

Technical Field

[0001] The present invention relates to the technical field of linear motors, and more specifically, to a linear motor with high stability performance. Background Art

[0002] A linear motor is a motor that directly converts electrical energy into linear motion mechanical energy. Its main structure is derived from a traditional rotary motor and realizes linear motion through unfolding or re - design. The working principle of a linear motor is based on the laws of electromagnetic induction and Lorentz force. Its basic mechanism is to directly generate linear motion through the interaction of current and magnetic field. It is an efficient and compact motion control device that directly converts electrical energy into linear motion based on the principle of electromagnetic induction and is widely used in industrial and high - tech fields.

[0003] Currently, in the industrial production environment, a linear motor is usually used to drive a high - precision processing device. However, in the factory environment, when the linear motor works, the primary coil is energized and generates heat, and the secondary coil generates heat due to eddy current loss. The heat will cause thermal expansion of the material, and the thermal expansion will cause a change in the gap, affecting the transmission stability. In the prior art, a cooling system is usually set on the linear motor to achieve a cooling effect to avoid these problems. However, in a factory environment where the ambient temperature is higher than normal temperature, due to the high ambient temperature, the heat in the air is difficult to dissipate continuously. The ambient temperature plus the heat generated during operation reduces the efficiency of the cooling system during heat dissipation, resulting in the continuous accumulation of heat inside the linear motor. Furthermore, it is easy to affect the operation stability due to the gap change caused by thermal expansion. Therefore, an open - type linear motor is usually used in a factory environment where the ambient temperature is higher than normal temperature.

[0004] However, in some environmental working areas, fine metal chips and dust are often generated. These impurities are easily inhaled into the motor interior during machine operation and enter between the stator and the mover. The metal chips that enter between the stator and the mover will change the path and intensity of the magnetic field, resulting in uneven magnetic field distribution. Furthermore, it will affect the uniformity of the magnetic field, causing inconsistent forces on the mover and affecting the stability during motion. Summary of the Invention

Detailed implementation manners

[0033] The present application will be further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Referring to the attached Figures 1 to 5 , a linear motor with high stability performance, comprising: a motor base 1, on which a stator 11 and a slide rail 15 are provided. A slide seat 12 is slidably arranged on the motor base 1. A mover 13 and a slider 14 are provided at the bottom of the slide seat 12. The stator 11 is adapted to the mover 13. The slider 14 is slidably arranged on the slide rail 15. An encoder 16 is further provided on one side of the slide seat 12. A cover plate 17 is provided on the top of the motor base 1, and both sides of the motor base 1 are open.

[0035] Air filtering mechanisms 2 are provided on both sides of the motor base 1. The air filtering mechanisms 2 include a filtering component 21 and a diversion component 22. The filtering component 21 includes a filter element 212, which is used to filter the air entering between the stator 11 and the mover 13 to reduce debris from entering between the stator 11 and the mover 13 and ensure the stability during its operation.

[0036] The diversion component 22 includes a rotatably arranged diversion cylinder 221. A plurality of air inlet holes 2211 are formed on the outer side of the diversion cylinder 221, and a through hole 2212 is formed in the diversion cylinder 221. The plurality of air inlet holes 2211 are all communicated with the through hole 2212, and the air outlet end of the through hole 2212 points to the space between the stator 11 and the mover 13. By rotating the diversion cylinder 221, the filtered air is introduced into the through hole 2212 through the plurality of air inlet holes 2211 and is accelerated and blown towards the space between the stator 11 and the mover 13 to accelerate air circulation and ensure its heat dissipation effect.

[0037] It should be noted that the encoder 16 is a sensor used to detect the moving position, speed and direction of the motor. It is a key component in the closed-loop control system of the linear motor, which can provide accurate position information to ensure the stable operation and high precision of the system. The filtering component 21 can be a filter screen, so that during the use of the linear motor, debris and dust around the linear motor are filtered by the filter screen to reduce the debris and dust entering between the stator 11 and the mover 13. The diversion cylinder 221 can be driven by a motor to rotate. The air inlet holes 2211 formed on the outer side of the diversion cylinder 221 are arc-shaped. When the diversion cylinder 221 is driven by a motor to rotate, as the diversion cylinder 221 rotates, the air filtered by the filter screen can enter the through hole 2212 through the air inlet holes 2211, and then the air enters between the stator 11 and the mover 13 through the through hole 2212. By guiding the air, the air circulation inside the linear motor can be accelerated and its heat dissipation effect can be improved.

[0038] The implementation scenario is as follows: First, the stator 11 is energized. When current passes through the electromagnetic coil of the stator 11, a magnetic field will be generated, and the magnetic material of the mover 13 will be affected by the magnetic field generated by the stator 11. According to the laws of electromagnetics, the change in the current of the stator 11 will cause the mover 13 to be subjected to a corresponding force, thereby realizing the linear movement of the mover 13. By controlling the direction and magnitude of the current, the acceleration, deceleration, and movement direction of the mover 13 can be precisely controlled. And in an industrial environment, due to the presence of other processing equipment, when debris and dust are generated around the linear motor, the debris and dust can be filtered through a filter screen. At the same time, by driving the drainage cylinder 221 to rotate, during the rotation of the drainage cylinder 221, the air filtered by the filter screen is introduced into the through hole 2212 through the air inlet hole 2211 and conveyed between the stator 11 and the mover 13, which plays a role in accelerating the air circulation to improve its heat dissipation effect. Thus, through the settings of the filtering component 21 and the drainage component 22, the problem that debris and dust are likely to enter the stator 11 and the mover 13 of the linear motor with an open design in a complex environment, resulting in the change of the magnetic field path and intensity, causing uneven magnetic field distribution and affecting the stability during movement, can be solved.

[0039] It should also be noted that when the linear motor is used at a relatively high ambient temperature, a conventional liquid cooling structure is provided in the linear motor. At this time, the drainage component 22 can be used to further improve its heat dissipation effect, reduce the possibility of thermal expansion of the linear motor materials caused by temperature rise, thereby reducing the gap change caused by thermal expansion, and further ensuring its transmission stability.

[0040] Further, referring to the attached drawings of the specification Figure 2 The filtering component 21 further includes a side cover 211. The side cover 211 is fixedly arranged on the side of the motor base 1. A ventilation opening is provided on the side cover 211, and a filter element 212 is arranged in the ventilation opening.

[0041] It should be noted that the filter element 212 is a filter screen, and the air flowing through the linear motor through the filter screen is used to reduce the debris and dust entering between the stator 11 and the mover 13.

[0042] Further, referring to the attached drawings of the specification Figure 4 and Figure 5 The drainage component 22 further includes a gear 222. The gear 222 is fixedly sleeved on the drainage cylinder 221. A rack 223 is fixedly arranged at the bottom of the side cover 211. The gear 222 meshes with the rack 223, and the drainage cylinder 221 is rotatably arranged on one side of the sliding seat 12.

[0043] It should be noted that when the linear motor is in use, when the mover 13 moves, the slide 12 moves synchronously, so that the slide 12 can drive the drainage tube 221 to move synchronously, and through the meshing transmission of the gear 222 and the rack 223, it can drive the drainage tube 221 to rotate, so that during the rotation of the drainage tube 221, the air can be drained and transported to the stator 11 and the mover 13, thereby accelerating the air circulation and improving its heat dissipation effect.

[0044] However, in the above technical solution, the air is filtered by the filter element 212 which is a filter screen. Since the aperture of the filter screen determines the size of the particles that it can block, smaller debris and dust may still be able to enter through the filter screen, causing the debris and dust to enter between the stator 11 and the mover 13. For this reason, the present invention further proposes an air suction mechanism 3. When the slide seat 12 moves linearly, the air suction mechanism 3 performs negative pressure suction to suck away the debris entering between the stator 11 and the mover 13. For details, refer to the attached manual. Figures 6 to 8 The bottom of the slide 12 is provided with an air extraction mechanism 3, which includes an air extraction cylinder 37 fixedly arranged at the bottom of the slide 12, and the air extraction end of the air extraction cylinder 37 points to the stator 11. The air extraction cylinder 37 extracts the debris and dust on the stator 11 from the stator 11 by exhausting air. The air extraction mechanism 3 also includes a piston 31 slidably arranged in the cover plate 17, and both ends of the piston 31 are fixedly arranged with connecting pieces 32. The ends of the two connecting pieces 32 away from the piston 31 are fixedly arranged on the slide 12. Guide members 33 are also provided on both sides of the machine base 1, and the two guide members 33 are respectively used to guide the corresponding connecting members 32. An air inlet hole 34 and an air outlet hole 35 are provided on the cover plate 17. Both the air inlet hole 34 and the air outlet hole 35 are provided with a one-way valve. The air inlet end of the air inlet hole 34 is connected to an exhaust pipe 36, and the exhaust pipe 36 is connected to an exhaust cylinder 37. An exhaust hole 371 is provided at the bottom of the exhaust cylinder 37, and the air inlet end of the exhaust hole 371 points to the stator 11.

[0045] It should be noted that the guide member 33 is a guide wheel and the connecting member 32 is a connecting rope. During the use of the linear motor, when the slide 12 moves, the mover 13 moves synchronously. At this time, the piston 31 can move simultaneously in the cover plate 17 through the guidance of the guide member 33 by the connecting member 32 and the guide wheel, and the movement direction of the piston 31 is opposite to that of the slide 12. Therefore, during the movement of the mover 13, when the piston 31 is driven to move simultaneously, the debris and dust between the stator 11 and the mover 13 can be sucked by negative pressure through the air inlet 34, the one-way valve arranged in the air inlet 34, the exhaust pipe 36 and the exhaust cylinder 37. At the same time, since the exhaust cylinder 37 is fixedly arranged on the slide 12, the exhaust cylinder 37 can be made to move synchronously with the mover 13, so that the debris and dust between the stator 11 and the mover 13 can be fully sucked.

[0046] It should also be noted that when the piston 31 moves to the right, under the action of negative pressure, the air with dust between the stator 11 and the mover 13 will be adsorbed between the adsorption covers 17. At this time, when the piston 31 moves from the right to the left again, the air with dust will be directly transported to the external air, and there is dust around the linear motor. At this time, it is easy for the dust to enter between the stator 11 and the mover 13 again. Therefore, the air outlet end of the first air outlet hole 35 can be extended to a water tank filled with water through a trachea to realize the purification treatment of the air with dust.

[0047] In the above technical solution, since the stator 11 and the mover 13 are usually made of iron or other magnetic materials, these materials can generate a strong magnetic field. When the linear motor works, the electromagnetic field generated after the stator 11 is energized will attract the surrounding magnetic metal debris, causing it to adhere inside the linear motor. At the same time, if the working magnetic field intensity of the linear motor is large enough to overcome the gravity of the magnetic debris, the magnetic debris will be adsorbed to the stator 11. At this time, if the debris entering between the stator 11 and the mover 13 is magnetic metal debris, it is easy for the magnetic metal debris to be adsorbed. At this time, it is difficult to suck away the adsorbed debris by suction. For this reason, the present invention also proposes a blowing mechanism 4, which blows the adsorbed debris by blowing and blows it onto the debris adhering seat 45, and the debris adhering seat 45 adheres to the magnetic debris. Specifically, referring to the attached Figure 9 and Figure 10 , a blowing mechanism 4 is further provided at the bottom of the sliding seat 12. The blowing mechanism 4 includes a partition plate 44 fixedly arranged at the bottom of the sliding seat 12. A plurality of first air blowing holes 441 are formed in the partition plate 44, and the air outlet ends of the plurality of first air blowing holes 441 all point to the stator 11. A debris adhering seat 45 is installed in the motor base 1. The partition plate 44 blows the debris on the stator 11 by blowing air, and the debris adhering seat 45 adheres to the debris blown by the blowing mechanism 4. The blowing mechanism 4 includes a blowing pipe 41. An air outlet hole 46 and an air inlet hole 47 are provided on the cover plate 17. One-way valves are provided in both the air outlet hole 46 and the air inlet hole 47. The air inlet end of the blowing pipe 41 is communicated with the air outlet hole 46. A filter component 42 is arranged at the end of the motor base 1. The air inlet end of the filter component 42 is communicated with the blowing pipe 41. The air outlet end of the filter component 42 is communicated with a connecting pipe 43. The partition plate 44 is communicated with the air outlet end of the connecting pipe 43, and the partition plate 44 is located between the stator 11 and the mover 13.

[0048] It should be noted that the partition 44 is made of plastic material that does not affect the magnetic field. A plurality of first air blowing holes 441 are arranged inside the partition 44, and they are all arranged at positions far from the left opening of the partition 44. Since the partition 44 is fixed to the bottom of the sliding seat 12 and moves synchronously with the sliding seat 12, when blowing air through the first air blowing holes 441 at this time, because the first air blowing holes 441 are arranged far from the left opening of the partition 44, through the shielding of the partition 44, it is possible to prevent debris from being blown out of the area outside the partition 44, ensure that the debris is inside the partition 44, and further avoid the debris from being blown scattered, which may cause difficulty in cleaning the debris and affect the magnetic field problem of the normal operation of the linear motor.

[0049] It should also be noted that the debris adhering seat 45 is a fixed seat with adhesive on its surface, and the connecting pipe 43 can be a telescopic corrugated pipe. During the use of the linear motor, when the sliding seat 12 moves, the mover 13 moves synchronously to drive the piston 31 to move, so that it sucks the debris between the stator 11 and the mover 13 through negative pressure suction. At the same time, as the piston 31 moves, the air in the cover plate 17 can be transported to the air filtering assembly 42 through the air blowing pipe 41, and the air filtered by the air filtering assembly 42 is transported to the partition 44 through the connecting pipe 43, and then blown onto the surface of the stator 11 through a plurality of first air blowing holes 441. Along with the movement of the sliding seat 12, the partition 44 moves synchronously. Thus, during the movement of the piston 31, through negative pressure, not only can the dust be sucked away, but also the debris that cannot be sucked away by adsorption can be blown away, and the debris is adhered by the debris adhering seat 45 for subsequent cleaning.

[0050] Further, referring to the attached Figure 11 and Figure 12 , the air filtering assembly 42 includes an air filtering box 421 and an air filtering element 422. The air filtering box 421 is fixedly installed at the end of the motor base 1, and the air filtering element 422 is installed in the air filtering box 421. The air filtering element 422 is used to filter the air entering the air filtering box 421.

[0051] It should be noted that the air filtering element 422 can be multi-layer filtered, and it can include a filter screen, an activated carbon filtering layer, etc. When the piston 31 moves to the right and then moves from the right to the left, under the action of negative pressure, it can suck external air into the cover plate 17 through the second air inlet hole 47. However, at this time, there is dust in the external air in the working environment. Therefore, it is necessary to filter the air through the air filtering assembly 42 and then blow it between the stator 11 and the mover 13.

[0052] Further, a chip blocking mechanism 5 is provided on the partition plate 44. The chip blocking mechanism 5 includes two drainage plates 52. The air inlet ends of the two drainage plates 52 are both communicated with the partition plate 44, and the air outlet ends of the two drainage plates 52 respectively point to the corresponding filter elements 212. The chip blocking mechanism 5 guides the air flow to blow air from the motor base 1 towards the filter elements 212. The chip blocking mechanism 5 further includes two connecting plates 51. The two connecting plates 51 are respectively installed on both sides of the partition plate 44. The two drainage plates 52 are respectively fixedly communicated with the corresponding connecting plates 51, and a plurality of second air blowing holes 53 are formed on both drainage plates 52. The plurality of second air blowing holes 53 on the same side all point to the corresponding filter elements 212.

[0053] It should be noted that during the process of the sliding seat 12 driving the partition plate 44 to move, at this time, the air inside the cover plate 17 is filtered and then conveyed into the partition plate 44 and then blown onto the stator 11. At the same time, under the action of the connecting plate 51, part of the air is conveyed into the drainage plate 52 through the connecting plate 51 and blown towards the filter element 212 through a plurality of second air blowing holes 53, so that the air can be blown from the inside to the outside of the linear motor towards the filter element 212, and the blown air flow can push the debris and dust away from the linear motor, reducing the possibility of entering between the stator 11 and the mover 13, thereby further reducing the entry of debris and dust between the stator 11 and the mover 13 and ensuring the stability of the linear motor during operation.

[0054] It should also be noted that the drainage assembly 22 and the chip blocking mechanism 5 are arranged in an interleaved manner, so that the drainage of air by the drainage assembly 22 and the blowing of air from the inside to the outside by the chip blocking mechanism 5 do not interfere with each other, avoiding air convection and affecting air circulation and causing problems affecting heat dissipation.

[0055] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
