Description

Technical Field

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

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

[0003] At present, in industrial production environments, linear motors are usually used to drive a high-precision processing equipment. However, in a factory environment, when the linear motor is working, the primary coil will generate heat when energized, and the secondary will generate heat due to eddy current loss. The heat will cause thermal expansion of the material, and thermal expansion will cause gap changes, affecting 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 and the continuous high temperature, it is difficult for the heat in the air to dissipate. The ambient temperature plus the heat generated during operation reduces the efficiency of the cooling system in heat dissipation, causing heat to accumulate continuously inside the linear motor, which is then easily caused by gap changes caused by thermal expansion, affecting the operating stability. Therefore, for factory environments where the ambient temperature is higher than normal temperature, an open linear motor is usually used.

[0004] However, in some working environments, fine metal chips and dust are often generated. These debris are easily sucked into the motor when the machine is running and enter between the stator and the mover. The metal chips entering between the stator and the mover will change the path and strength of the magnetic field, resulting in uneven distribution of the magnetic field, which in turn affects the uniformity of the magnetic field, causing inconsistent force on the mover and affecting stability during movement. Summary of the invention

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Refer to the instruction manual Figures 1 to 5 A linear motor with high stability performance comprises: a motor base 1, a stator 11 and a slide rail 15 are arranged on the motor base 1, a slide seat 12 is slidably arranged on the motor base 1, a mover 13 and a slider 14 are arranged at the bottom of the slider 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 also arranged on one side of the slider 12, a cover plate 17 is arranged on the top of the motor base 1, and both sides of the motor base 1 are open-type settings; An air filter mechanism 2 is provided on both sides of the motor base 1. The air filter mechanism 2 includes a filter assembly 21 and a drainage assembly 22. The filter assembly 21 includes a filter element 212. The filter element 212 is used to filter the air entering between the stator 11 and the mover 13 to reduce debris entering between the stator 11 and the mover 13, thereby ensuring its stability during operation. The drainage component 22 includes a rotatable drainage tube 221, a plurality of air inlet holes 2211 are provided on the outer side of the drainage tube 221, and a through hole 2212 is provided inside the drainage tube 221. The plurality of air inlet holes 2211 are all connected with the through hole 2212, and the air outlet end of the through hole 2212 points to between the stator 11 and the mover 13. The drainage component 22 introduces the filtered air into the through hole 2212 through the rotation of the drainage tube 221, and accelerates the air to be blown between the stator 11 and the mover 13, so as to accelerate the air circulation and ensure its heat dissipation effect.

[0032] It should be noted that the encoder 16 is a sensor for detecting the moving position, speed and direction of the motor. It is a key component in the closed-loop control system of the linear motor and can provide accurate position information to ensure that the system runs stably and with high precision. The filter component 21 can be a filter screen, so that when the linear motor is in use, the filter screen can filter the debris and dust around the linear motor to reduce the debris and dust entering between the stator 11 and the mover 13. The drainage tube 221 can be driven to rotate by a motor, and the air inlet 2211 opened on the outside of the drainage tube 221 is arranged in an arc shape. When the drainage tube 221 is driven to rotate by the motor, as the drainage tube 221 rotates, the air filtered by the filter screen can enter the through hole 2212 through the air inlet hole 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 in the linear motor can be accelerated and its heat dissipation effect can be improved.

[0033] The specific implementation scenario is as follows: first, the stator 11 is energized. When the current passes through the electromagnetic coil of the stator 11 , a magnetic field is generated, and the magnetic material of the mover 13 is affected by the magnetic field generated by the stator 11 . According to the laws of electromagnetism, the current change 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, and by controlling the direction and magnitude of the current, the acceleration, deceleration and movement direction of the mover 13 can be accurately controlled. 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. At the same time, by driving the drainage tube 221 to rotate, the drainage tube 221 introduces the air filtered by the filter into the through hole 2212 through the air inlet hole 2211 during the rotation, and transports it to between the stator 11 and the mover 13, thereby accelerating the air circulation to improve its heat dissipation effect. Therefore, the setting of the filter component 21 and the drainage component 22 can solve the problem that debris and dust are easily introduced into the stator 11 and the mover 13 of the open-design linear motor in a complex environment, resulting in changes in the path and intensity of the magnetic field, causing uneven distribution of the magnetic field, and affecting the stability during movement.

[0034] It should also be noted that when the linear motor is used in a higher 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 and reduce the possibility of thermal expansion of the linear motor material caused by temperature rise, thereby reducing the gap changes caused by thermal expansion and further ensuring its transmission stability.

[0035] For further information, please refer to the attached manual. Figure 2 The filter assembly 21 further includes a side cover 211, which is fixedly disposed on the side of the motor base 1. A vent is provided on the side cover 211, and a filter element 212 is disposed in the vent.

[0036] It should be noted that the filter element 212 is a filter screen, through which the air in the linear motor flows to reduce debris and dust that enter between the stator 11 and the mover 13 .

[0037] For further information, please refer to the attached manual. Figure 4 and Figure 5 The drainage assembly 22 also includes a gear 222, which is fixedly sleeved on the drainage tube 221. A rack 223 is fixedly provided at the bottom of the side cover 211. The gear 222 is meshed with the rack 223, and the drainage tube 221 is rotatably provided on one side of the slide seat 12.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] It should also be noted that when the piston 31 moves to the right, under the action of negative pressure, the air containing dust between the stator 11 and the mover 13 will be adsorbed between the cover plates 17. At this time, when the piston 31 moves from the right to the left again, the air containing dust will be directly transported to the outside air and exist around the linear motor. At this time, it is easy for dust to re-enter between the stator 11 and the mover 13. Therefore, the air outlet end of the air outlet 35 can be extended to a water tank filled with water through an air pipe to purify the dusty air.

[0042] In the above technical scheme, 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 is working, the electromagnetic field generated after the stator 11 is energized will attract the surrounding magnetic metal debris, causing it to adhere to the inside of the linear motor. At the same time, if the working magnetic field strength of the linear motor is large enough, it can overcome the gravity of the magnetic debris, causing the magnetic debris to be adsorbed onto the stator 11. At this time, if the debris entering the stator 11 and the mover 13 is magnetic metal debris, it is easy to cause 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 sticking seat 45, and adheres the magnetic debris by the debris sticking seat 45. For details, refer to the attached manual. Fig. 9 and Fig.10 The bottom of the slide 12 is also provided with a blowing mechanism 4, which includes a partition 44 fixedly provided at the bottom of the slide 12, and a plurality of blowing holes 441 are provided on the partition 44, and the outlet ends of the plurality of blowing holes 441 are all directed toward the stator 11, and a debris sticking seat 45 is installed in the motor base 1, and the partition 44 blows the debris on the stator 11 by blowing, and the debris blown by the blowing mechanism 4 is adhered by the debris sticking seat 45, and the blowing mechanism 4 includes a blowing pipe 41, and the cover plate 17 An air outlet hole 46 and an air inlet hole 47 are provided on the upper surface, and a one-way valve is provided in the air outlet hole 46 and the air inlet hole 47. The air inlet end of the air blowing pipe 41 is connected with the air outlet hole 46. An air filter component 42 is provided at the end of the motor base 1. The air inlet end of the air filter component 42 is connected with the air blowing pipe 41, and the air outlet end of the air filter component 42 is connected with a connecting pipe 43. The partition plate 44 is connected 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.

[0043] It should be noted that the partition 44 is made of plastic material that does not affect the magnetic field. The multiple blowing holes 441 arranged inside the partition 44 are all arranged at a position away from the opening on the left side of the partition 44. Since the partition 44 is fixed to the bottom of the slide 12, it moves synchronously with the slide 12. At this time, when blowing through the blowing hole 441, since the blowing hole 441 is arranged away from the opening on the left side of the partition 44, the debris can be blocked by the partition 44 to prevent the debris from being blown away from the area outside the partition 44, ensuring that the debris is inside the partition 44, thereby preventing the debris from being blown away, which makes it difficult to clean the debris and affects the magnetic field problem of normal operation of the linear motor.

[0044] It should also be noted that the debris sticking seat 45 is a fixed seat with adhesive on the surface, and the connecting pipe 43 can be a retractable bellows. During the use of the linear motor, when the slide 12 moves, the mover 13 moves synchronously to drive the piston 31 to move, so that the debris between the stator 11 and the mover 13 can be extracted by 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 filter assembly 42 through the blowing pipe 41, and the air filtered by the air filter 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 blowing holes 441, and the partition 44 moves synchronously with the movement of the slide 12. Therefore, in the process of the movement of the piston 31, not only the dust can be sucked away by the negative pressure, but also the debris that cannot be sucked away by adsorption can be blown away, and the debris can be adhered to the debris sticking seat 45 for subsequent cleaning.

[0045] For further information, please refer to the attached manual. Fig.11 and Fig.12 The air filter assembly 42 includes an air filter box 421 and an air filter element 422. The air filter box 421 is fixedly mounted on the end of the motor base 1. The air filter element 422 is mounted in the air filter box 421. The air filter element 422 is used to filter the air entering the air filter box 421.

[0046] It should be noted that the air filter 422 can be a multi-layer filter, which may include a filter screen, an activated carbon filter layer, etc. When the piston 31 moves to the right and then moves from the right to the left, it can suck the external air into the cover plate 17 through the air inlet 47 under the action of negative pressure. However, at this time, there is dust in the working environment in the external air, so the air needs to be filtered through the air filter component 42 and then blown between the stator 11 and the mover 13.

[0047] Furthermore, a chip blocking mechanism 5 is provided on the partition 44, and the chip blocking mechanism 5 includes two guide plates 52, the air inlet ends of the two guide plates 52 are connected to the partition 44, and the air outlet ends of the two guide plates 52 respectively point to the corresponding filter elements 212, and the chip blocking mechanism 5 guides the airflow from the motor base 1 to blow air to the filter element 212. The chip blocking mechanism 5 also includes two connecting plates 51, and the two connecting plates 51 are respectively installed on both sides of the partition 44, and the two guide plates 52 are respectively fixedly connected to the corresponding connecting plates 51, and a plurality of blowing holes 53 are opened on the two guide plates 52, and the multiple blowing holes 53 located on the same side all point to the corresponding filter elements 212.

[0048] It should be noted that, in the process of the slide 12 driving the partition 44 to move, the air in the cover plate 17 is filtered and then transported to the partition 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 transported to the guide plate 52 through the connecting plate 51, and blown to the filter element 212 through multiple blowing holes 53, so that air can be blown from the inside to the outside of the linear motor onto the filter element 212, so that the airflow blown out can push 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 debris and dust entering between the stator 11 and the mover 13, and ensuring the stability of the linear motor during operation.

[0049] It should also be noted that the drainage component 22 and the chip blocking mechanism 5 are staggered so that the drainage of air by the drainage component 22 and the blowing from the inside to the outside by the chip blocking mechanism 5 do not interfere with each other, thereby avoiding air convection that affects air circulation and causes problems affecting heat dissipation.

[0050] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
