Description

Technical Field

[0001] The present invention relates to the field of motor technology, and more specifically, to a multi-section combinable linear motor module. Background Art

[0002] A linear motor is an electric drive device that converts electrical energy directly into mechanical energy for linear motion. It does not require an intermediate conversion mechanism and can achieve direct linear motion drive. Among them, a coreless linear motor is a special type of linear motor that does not have an iron core like in traditional motors. The iron core is mainly used to enhance the magnetic field and guide the magnetic circuit in conventional motors, but the coreless linear motor adopts a different design concept and uses other methods to achieve electromagnetic induction and generate linear motion. It is mainly composed of two parts: the stator and the mover.

[0003] A base plate is installed inside the stator of the coreless linear motor, which provides stability and heat dissipation through the support of the base plate. However, the traditional base plate is inserted between the magnetic holes of the left and right armature coils in two rows. Due to the decrease in the gap flux density, the gap magnetic field becomes longer, and the momentum between the mover and the stator will decrease. At this time, if the coreless linear motor generates a certain thrust, the current flowing through the armature coil will increase, which will increase the Joule loss and cause the temperature of the linear motor armature surface to rise. Due to the Joule loss, the thermal resistance of the armature increases, and the temperature of the armature coil rises, resulting in an increase in the temperature of the coreless linear motor armature surface. The increase in temperature will affect the magnetic force of the magnets in the stator and mover, thereby reducing the electromagnetic thrust between the stator and mover and reducing the movement speed. Therefore, we designed a multi-segment combinable linear motor module. Summary of the invention

[0004] The present invention provides a multi-section combinable linear motor module, which solves the problem in the related art that the traditional substrate is arranged in two rows and inserted between the magnetic holes of the left and right armature coils.

[0019] like Figures 1 to 10 As shown, a multi-section combinable linear motor module according to an embodiment of the present invention includes a stator, which is composed of a yoke 1 and a permanent magnet 2. A mover is arranged inside the yoke 1, and the mover includes an armature connecting plate 401. Two armature coils 404 are arranged below the armature connecting plate 401, and a substrate 402 is arranged between the two armature coils 404. A plurality of infusion grooves 514 are opened in the substrate 402, and a coolant is arranged inside the infusion groove 514. The substrate 402 and the armature coil 404 are adhered to the armature connecting plate 401 through a mold resin 403. The two armature coils 404 form a Y shape, so that the length of the substrate 402 between the two armature coils 404 is shortened. After the mover is energized, the shortened substrate 402 increases the electromagnetic thrust between the mover and the stator; a cooling mechanism is arranged on the armature connecting plate 401, and an air supply mechanism is connected to the cooling mechanism. The cooling mechanism cooperates with the air supply mechanism to accelerate the heat transfer of the substrate 402 to the armature coil 404 during the movement of the mover.

[0020] Please refer to Figure 1, a plurality of permanent magnets 2 are fixedly mounted inside the yoke 1, the magnetic poles of two adjacent permanent magnets 2 are opposite, a cable is mounted on the armature connecting plate 401, and the cable is connected to the armature coil 404; Please refer to Figures 3 to 6 The cooling mechanism includes a cooling box 501, which is fixedly connected to the armature connecting plate 401. A partition 502 is fixedly installed inside the cooling box 501. The first partition 502 divides the cooling box 501 into two spaces. A first air delivery pipe 517 is fixedly connected to the cooling box 501. A rotating box 508 is rotatably installed on the first air delivery pipe 517. A plurality of bent pipes 507 are fixedly installed on the rotating box 508. A crown gear 509 is fixedly installed on the rotating box 508. The crown gear 509 is meshed with a second gear. Wheel 512, the second gear 512 is fixedly connected with the second reciprocating screw 510, the second reciprocating screw 510 is threadedly connected with a threaded sleeve 513, the threaded sleeve 513 is fixedly connected with the second pressure plate 505, the second pressure plate 505 is slidably connected with the cooling box 501 and the partition 502, a first pressure plate 503 is arranged on the right side of the second pressure plate 505, the first pressure plate 503 is slidably connected with the cooling box 501 and the partition 502, and the first pressure plate 503 is connected to the armature connecting plate 401 through a first spring 504.

[0021] Please refer to Figure 1 , Figure 7 The air supply mechanism includes a mounting cover 301, which is fixedly mounted on the yoke 1. A plurality of first connecting pipes 303 are fixedly mounted inside the mounting cover 301. Two adjacent first connecting pipes 303 are rotatably connected via a rotating pipe 302. The first air supply pipe 517 is connected to the first connecting pipe 303 at the end of the mounting cover 301 via a hose.

[0022] The present invention further transmits the basically absorbed heat on the basis of changing the length of the base plate 402, thereby reducing the temperature of the armature coil 404, thereby enhancing the electromagnetic thrust between the mover and the stator. The specific method is as follows: firstly, the first connecting tube 303 is connected to the external gas supply equipment to provide gas to the inside of the first connecting tube 303, and then connected to the external power supply through a cable to energize the armature coil 404. When the predetermined current reaches the armature coil 404 through the cable, a thrust is generated at the mover through the effect of the magnetic field generated by the permanent magnet 2, so that the mover is in the magnetic yoke 1. The two armature coils 404 form a Y shape, so that the substrate 402 is located at the bifurcated gap, so that the length that the substrate 402 can extend will be shortened. When the length of the substrate 402 between the two armature coils 404 is reduced, the interference range of the magnetic field propagation path is also reduced accordingly. In the coreless linear motor, the magnetic field generated by the armature coil 404 is transmitted between the air gap and other components. An overly long substrate 402 may change the direction of the magnetic field line. After shortening the length of the substrate 402, the magnetic field distortion caused by the substrate 402 is reduced, thereby optimizing the magnetic field distribution; and The magnetic flux density is related to the effective passage area of ​​the magnetic field. Shortening the length of the substrate 402 can increase the effective action area of ​​the magnetic field between the armature coil 404 and the air gap. When the magnetic flux remains unchanged, the increase in the effective area helps to increase the gap magnetic flux density. The increase in the gap magnetic flux density will directly affect the electromagnetic thrust of the motor. The electromagnetic thrust is related to the magnetic flux density and the current. The increase in the magnetic flux density means that under the same current, the electromagnetic thrust generated by the motor increases, which makes the propulsion to current ratio increase accordingly. The motor can generate greater mechanical thrust while consuming the same electrical energy, thereby improving the performance of the motor. Due to the increase in the propulsion to current ratio, the required current can be reduced when the same propulsion force is achieved. The reduction in current will reduce the rope loss, which not only reduces the heat generation inside the motor, but also is conducive to the long-term stable operation of the motor. After the rope loss is reduced, the heat generated by the armature is reduced, which can alleviate the problem of excessive temperature rise on the armature surface. At the same time, shortening the length of the substrate 402 also reduces the temperature rise caused by the heat absorbed by the substrate 402 itself, which helps to maintain the motor running at a lower temperature and further improve the motor performance and stability.During the movement of the mover, the gas entering the first connecting pipe 303 will also enter the rotating box 508 and spray out from the bent pipe 507. Due to the setting of the bent pipe 507, the rotating box 508 will rotate, so that the second pressing plate 505 will squeeze the coolant to circulate in the base plate 402. The circulating coolant can continuously transport the heat absorbed by the base plate 402, so as to better dissipate heat for the armature coil 404 and reduce the temperature of the armature coil 404 during operation. This can effectively reduce the influence of temperature on the electromagnetic thrust between the stator and the mover, so that the stator and the mover can always maintain a stable state of operation. The gas entering the first connecting pipe 303 will also pass through the rotating pipe 302. Since the nozzle 321 is obliquely installed on the rotating pipe 302, part of the gas will also be sprayed into the inside of the magnetic yoke 1 to avoid heat dissipation for the stator and the mover, and to avoid the temperature in the gap between the mover and the stator being too high to affect the operation of the mover. ;

[0023] Please refer to Figure 5 , Figure 6 A pull rope 515 is provided inside the infusion tank 514, and an expansion ring 516 is fixedly installed on the pull rope 515. The expansion ring 516 contacts the substrate 402. The two ends of the pull rope 515 are respectively fixedly connected to the first pressing plate 503 and the second pressing plate 505. The setting of the expansion ring 516 can further ensure that the heat exchange effect between the substrate 402 and the coolant can be maximized on the basis of the first pressing plate 503 and the second pressing plate 505 squeezing the coolant to accelerate the cooling of the substrate 402. The specific operation is as follows: when the second pressing plate 505 is pressed down, the second pressing plate 505 relaxes the pulling of the pull rope 515, so that the first pressing plate 503 will move up under the action of the first spring 504 to pull the pull rope 515, so that the expansion ring 516 moves inside the infusion tank 514, and the moving expansion ring 5 16 will scrape the inner wall of the infusion groove 514 and clean some attachments on the inner wall, so that the heat exchange effect between the substrate 402 and the coolant can be maximized. Since a liquid outlet pipe 511 is also arranged under the first pressing plate 503, the two ends of the liquid outlet pipe 511 are hard pipes and the middle is a soft pipe. A limit frame 506 is fixedly installed inside the top of the liquid outlet pipe 511, and the pull rope 515 runs through the limit frame 506. In this way, during the up and down movement of the first pressing plate 503, the pull rope 515 drives the hard pipe at the top of the liquid outlet pipe 511 to move, so that the injection position of the liquid outlet pipe 511 changes, so that the coolant squeezed to the first pressing plate 503 can be more chaotically fused, so that the coolant with a higher temperature can be mixed with the coolant with a lower temperature, so that the coolant can better cool the substrate 402.

[0024] Please refer to Figures 7 to 10A mounting box 304 is fixedly mounted on the mounting cover 301, a third pressure plate is slidably connected inside the mounting box 304, a protruding column 305 is fixedly connected to the third pressure plate, a top of the protruding column 305 penetrates the mounting box 304 and extends to the outside of the mounting box 304, a second spring 322 is sleeved on the protruding column 305, two ends of the second spring 322 are respectively connected to the mounting box 304 and the third pressure plate, a driving frame 313 is fixedly connected to the bottom of the third pressure plate, a plurality of latch teeth 317 are fixedly mounted inside the driving frame 313, a first gear 316 is meshed on the latch teeth 317, a connecting rod 315 is fixedly connected to the first gear 316, a first rotating shaft 314 is fixedly mounted on the connecting rod 315, the first rotating shaft 314 is rotatably connected to the mounting box 304, a tooth groove is provided on the first gear 316, and a tooth groove is provided inside There is a matching toggle plate 318, on which a driving disk 319 is installed, on which a first reciprocating screw rod 320 is fixedly installed, the first reciprocating screw rod 320 is rotatably connected to the installation box 304, a threaded plate 312 is threadedly connected to the first reciprocating screw rod 320, on which a slide bar 310 is fixedly connected, the slide bar 310 is slidably connected to the installation box 304, a driving rod 309 is fixedly connected to the slide bar 310, a driving column 308 is arranged above the driving rod 309, a track groove 311 is opened on the driving column 308, the track groove 311 matches the driving rod 309, the driving column 308 is rotatably connected to the installation box 304, a pulley 307 is fixedly connected to the driving column 308 and the rotating tube 302, and the two pulleys 307 are connected by a connecting belt 306.

[0025] The present invention provides a raised column 305. During the movement of the mover, gas is introduced to allow the mover to operate more stably. The movement of the mover squeezes the raised column 305. The raised column 305 drives the latch 317 to act on the first gear 316, so that the driving column 308 drives the rotating tube 302 to reciprocate at a small angle. In this way, the injection angle of the nozzle 321 on the rotating tube 302 will change, and the position where the ejected gas can act will also change, so that the surfaces of the mover and the stator can be cooled more comprehensively, thereby improving the stability between the mover and the stator.

[0026] Working principle: First, connect the first connecting tube 303 to the external gas supply equipment to provide gas for the inside of the first connecting tube 303, and then connect it to the external power supply through the cable to energize the armature coil 404. When the predetermined current reaches the armature coil 404 through the cable, a thrust is generated at the mover through the effect of the magnetic field generated by the permanent magnet, so that the mover moves back and forth in the yoke 1. During the movement of the mover, the inside of the first connecting tube 303 will continuously transport gas to the inside of the rotating box 508, and then spray it out from the bent pipe 507. Due to the effect of the bent pipe 507, the rotating box 508 will rotate, and the rotation of the rotating box 508 will pass through the crown gear 509. The second reciprocating screw rod 510 rotates with the first gear 316, and the second reciprocating screw rod 510 drives the second pressing plate 505 to move up and down. When the second pressing plate 505 moves down, the second pressing plate 505 squeezes the coolant, so that the coolant is transported to the first pressing plate 503. When the coolant enters the first pressing plate 503, the first pressing plate 503 moves up under the action of the first spring 504 and pulls the pull rope 515, so that the pull rope 515 drives the expansion ring 516 to clean the infusion tank 514. In the process of the pull rope 515 moving up, the position of the outlet pipe 511 will change due to the position of the pull rope 515, thereby changing the delivery direction of the coolant, so that the coolant can be transported to the first pressing plate 503. The second pressing plate 505 is fully mixed. When the second pressing plate 505 moves up, it is restored to its original state by means of the pull rope 515 and the first spring 504. Then, it keeps running back and forth to deliver heat from the armature coil 404 to the substrate 402. The gas entering the first connecting pipe 303 is also sprayed to the inside of the yoke 1 through the rotating pipe 302 and the nozzle 321 to position and cool the surface of the mover. The movement of the mover will continuously squeeze the protruding column 305, so that the protruding column 305 drives the driving frame 313 to move through the third pressing plate. The movement of the driving frame 313 drives the first gear 316 to rotate through the latch 317. The rotation of the first gear 316 drives the first reciprocating The screw rod 320 rotates, and the rotation of the first reciprocating screw rod 320 will cause the threaded plate 312 and the slide rod 310 to drive the drive rod 309 to continuously reciprocate and drive the drive column 308, so that the drive column 308 will drive the rotating tube 302 to reciprocate at a small angle through the pulley 307 and the connecting belt 306, so that the nozzle 321 continuously changes its position to transport gas, so that the transported gas can cover the stator and the mover in a larger range, cool them down, and ensure the stability between the stator and the mover. The first connecting tube can also be connected to the first connecting tubes on the remaining DC motor modules, so that multiple DC motor modules can be combined together, work in sections, and share a gas source to work.
