Description

Technical Field

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

[0002] The linear motor slide operates on the electromagnetic drive mechanism of a linear motor. Its structural design features a stable magnetic field created by a layer of alternating north and south-pole permanent magnets arranged flat on the bottom of the slide. The main body of the mover, located above the slide, is made of iron and embedded with multiple sets of conductive coils, forming independently controlled electromagnet units. These electromagnet units are the core components that drive the mover's motion. Precisely controlling the power supply state of each electromagnet enables directional motion of the mover within the magnetic field. Specifically, when the electromagnet coils are energized, the resulting current magnetic field, in accordance with Ampere's law, interacts with the inherent magnetic field of the permanent magnets below. To achieve continuous linear motion of the mover, the system employs a time-sharing power-on strategy: first, the first electromagnet is activated, generating a magnetic field that propels the mover a specific distance. Immediately, the second electromagnet is energized, while the power supply to the first electromagnet is simultaneously disconnected, allowing the mover to continue moving under the driving force of the second electromagnet. This process, through the sequential activation and de-energization of the electromagnet groups, achieves continuous linear motion of the mover on the permanent magnet track.

[0003] The linear motor rotor generates heat due to continuous power-on operation. Especially when the rotor carries heavy objects and performs reciprocating motion, the high temperature accumulated inside it will cause the magnetic degradation of the material. The high temperature causes the magnetic domain structure of the rotor core (such as silicon steel sheet) to be disordered and the magnetic permeability to decrease. At the same time, it may cause the residual magnetism of the permanent magnet to weaken, resulting in a decrease in the magnetic field strength. This magnetic weakening will directly interfere with the precise control of the electromagnetic force, causing the rotor to have position deviation, speed fluctuation or insufficient thrust during reciprocating motion, and ultimately affect the guide positioning accuracy and repeatability of the linear motor.

[0056] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0057] Example 1

[0058] like Figures 1 to 2 As shown, a linear motor module with high guiding precision according to an embodiment of the present invention is characterized by comprising:

[0059] A linear motor body 1; a slide 2, slidably arranged on the linear motor body 1;

[0060] The electromagnet 3 is assembled in the slide 2 and is magnetically matched with the linear motor body 1;

[0061] The circulating cooling mechanism 4 is placed with a heavy object to circulate heat inside the slide 2;

[0062] The return member 5 is connected with the circulating cooling mechanism 4 so as to store energy when the weight acts;

[0063] The rotating air inlet mechanism 6 is arranged on the two moving sides of the slide 2 and cooperates with the return member 5 in transmission, so that when heavy objects are placed on or removed from the circulating cooling mechanism 4, the rotating air inlet mechanism 6 is driven to intake air while changing the exhaust direction to act on the electromagnet 3.

[0064] The linear motor body 1 provides basic support and magnetic field environment for the entire module. The slide 2 can slide on it to achieve linear motion. The electromagnet 3 is installed in the slide 2 and magnetically cooperates with the linear motor body 1. By energizing, it generates a magnetic field, which interacts with the magnetic field of the linear motor body 1, thereby driving the slide 2 to move. The circulating cooling mechanism 4 starts to work when a heavy object is placed, and uses the coolant circulation to take away the heat generated by the electromagnet 3 inside the slide 2, reducing the phenomenon of magnetic degradation caused by heat accumulation, and improving the guiding positioning accuracy and repeatability of the linear motor. The return member 5 cooperates with the circulating cooling mechanism 4 to store energy when a heavy object acts and release energy when the heavy object is removed. The rotating air inlet mechanism 6 cooperates with the return member 5 in transmission. In the process of placing or removing heavy objects from the circulating cooling mechanism 4, on the one hand, external air is introduced, and on the other hand, the exhaust direction is changed to cool the electromagnet 3, further enhancing the heat dissipation effect and ensuring the stable performance of the electromagnet 3.

[0065] like Figure 2 and Figures 4 to 6 As shown, the circulating cooling mechanism 4 includes a cooling water tank 41 fixed to the slide 2; a box body 42 with an upward opening, connected to the return member 5; a bearing plate 43, slidably arranged inside the box body 42; a return spring 44, both ends of which are respectively connected to the bearing plate 43 and the inner bottom wall of the box body 42; a spiral tube 45, arranged at the outer periphery of the electromagnet 3; a liquid inlet pipe 46, one end of which is connected to the bottom of the box body 42 and the other end is connected to the spiral tube 45; a one-way discharge pipe 47, which is connected between the spiral tube 45 and the cooling water tank 41, so that the spiral tube 45 can discharge liquid to the cooling water tank 41 in one direction; a connecting pipe 48, which is connected to the cooling water tank 41 Between the water tank 41 and the box body 42, the box body 42 allows the box body 42 to extract the liquid in the cooling water tank 41 in a unidirectional manner; the suction cup 410 is installed on the supporting plate 43 to adsorb the heavy object, which is conducive to the rapid transfer of the heavy object. At the same time, when the heavy object is removed, it acts on the return member 5, so that the return member 5 is stretched and then restored, and acts reciprocatingly on the rotating air inlet mechanism 6; there is coolant inside the box body 42, the liquid inlet pipe 46, the spiral tube 45, the one-way discharge pipe 47 and the connecting pipe 48. There is coolant inside. There are two cooling water tanks 41, so that when the temperature of the coolant inside one cooling water tank 41 rises, it switches to the other cooling water tank 41.

[0066] It should be noted that the cooling water tank 41 is used to store coolant and provide a cold source for circulating cooling. The box body 42 is connected to the return member 5, and the bearing plate 43 can slide in the box body 42. When a heavy object is placed on the suction cup 410, the bearing plate 43 is pressed down, compressing the return spring 44, and the coolant in the box body 42 is squeezed. The return spring 44 stores energy, and at the same time the pressure in the box body 42 increases, and the coolant is pressed into the spiral tube 45 through the liquid inlet pipe 46. The spiral tube 45 surrounds the outer periphery of the electromagnet 3. After the coolant absorbs the heat generated by the electromagnet 3, it flows back to the cooling water tank 41 through the one-way discharge pipe 47, and the box body 42 draws coolant from the cooling water tank 41 through the connecting pipe 48, forming a cycle. The suction cup 410 The adsorption of heavy objects facilitates the transfer of loads. When the heavy objects are removed, the return spring 44 rebounds, driving the load-bearing plate 43 to rise, and at the same time acts on the return member 5, causing the return member 5 to stretch and then return, thereby driving the rotating air inlet mechanism 6 to work; one spiral tube 45 corresponds to two cooling water tanks 41, and one spiral tube 45 is connected to one cooling water tank 41 when in use. Two cooling water tanks 41 are set up, and when the heat of one cooling water tank 41 is high, it can switch to the other cooling water tank 41 (a temperature sensor is provided inside the cooling water tank 41 to sense the internal temperature of the cooling water tank 41, and the cooling water tank 41 is switched to be used according to the set temperature), which can ensure that the coolant always has a good cooling effect and continuously and stably dissipates heat for the electromagnet 3.

[0067] It should be noted that the supporting plate 43 is connected to the inner bottom wall of the box body 42 via a limiting rope, so as to limit the movement range of the supporting plate 43 and prevent it from moving out of the box body 42 .

[0068] Furthermore, the cooling water tank 41 is provided with heat dissipation fins 49 , and a plurality of heat dissipation fins 49 are provided and evenly divided into two groups and symmetrically arranged.

[0069] The heat dissipation fins 49 increase the heat dissipation area of ​​the cooling water tank 41. After the coolant flows back to the cooling water tank 41, the heat dissipation fins 49 dissipate the heat of the coolant into the surrounding air. Multiple groups of symmetrically arranged heat dissipation fins 49 allow the slide 2 to contact the air for heat dissipation when moving back and forth, thereby improving the heat dissipation efficiency, accelerating the cooling of the coolant, and allowing the coolant in the cooling water tank 41 to recover to a low temperature more quickly, preparing for the next round of circulating cooling, and further ensuring the heat dissipation effect of the circulating cooling mechanism 4.

[0070] The circulating cooling mechanism 4 further includes a one-way valve 411 provided on the one-way discharge pipe 47 and the connecting pipe 48 .

[0071] The one-way valve 411 is a one-way solenoid valve.

[0072] It should be noted that the one-way valve 411 is installed on the one-way discharge pipe 47 and the connecting pipe 48 to ensure that the coolant can only flow in the specified direction. On the one-way discharge pipe 47, the one-way valve 411 ensures that the coolant after absorbing heat in the spiral tube 45 can only flow to the cooling water tank 41 to prevent the coolant from flowing back; on the connecting pipe 48, the one-way valve 411 ensures that the box body 42 can only draw coolant from the cooling water tank 41 to avoid the coolant in the box body 42 flowing back to the cooling water tank 41, thereby maintaining the normal circulation of the coolant and ensuring the stable operation of the circulating cooling mechanism 4.

[0073] like Figures 2 to 4 As shown, the return member 5 includes a moving rod 51 installed at the bottom of the box body 42, one end of the moving rod 51 slides into the interior of the slide 2 and cooperates with the rotating air inlet mechanism 6; the reciprocating spring 52 is sleeved on the outer periphery of the moving rod 51, one end is fixed to the box body 42, and the other end is fixed to the slide 2.

[0074] It should be noted that the moving rod 51 is connected to the box body 42. When a heavy object is placed on the suction cup 410 to cause the box body 42 to descend, the moving rod 51 moves downward accordingly, compressing the reciprocating spring 52 and storing elastic potential energy. After the heavy object is removed, the reciprocating spring 52 rebounds, pushing the moving rod 51 to move upward. The moving rod 51 is coordinated with the rotating air intake mechanism 6. During its up and down movement, it drives the rotating air intake mechanism 6 to operate, cooperates with the movement of the slide 2, realizes the air intake action, and dissipates heat for the electromagnet 3. At the same time, the elastic restoring force of the reciprocating spring 52 is utilized to ensure that the rotating air intake mechanism 6 can work continuously and stably.

[0075] When the heavy object is adsorbed by the suction cup 410 and continuously drives the carrying plate 43 into the box body 42, the suction cup 410 adsorbs the bottom of the heavy object, and the box body 42 blocks the side of the heavy object, so as to facilitate the rapid movement of the heavy object.

[0076] like Figure 3 As shown, a spoiler 53 adapted to the interior of the slide 2 is installed on the moving rod 51, and holes are opened on the spoiler 53 to enable it to move up and down smoothly.

[0077] The spoiler 53 is installed on the moving rod 51. When the moving rod 51 moves up and down as the weight is placed or removed, the spoiler 53 stirs the air inside the slide 2. On the one hand, it speeds up the flow of air inside the slide 2 so that heat can be taken away more quickly; on the other hand, it changes the direction of air flow so that the air can contact the heating components of the electromagnet 3 more evenly, thereby improving the air cooling effect, further reducing the internal temperature of the slide 2, and ensuring the performance of the electromagnet 3.

[0078] like Figure 2 、 Figure 7 and Figure 7 As shown, the rotary air inlet mechanism 6 includes a rotary disc 61 rotatably arranged on the travel side of the slide 2, on which a filter hole 611 is opened;

[0079] The guide tube 62 has one end fixedly mounted on the filter hole 611 and the other end extending into the interior of the slide 2;

[0080] The spray member is provided at the exhaust end of the flow guide pipe 62 .

[0081] It should be noted that when the turntable 61 rotates, along with the movement of the slide 2, the air on the traveling side enters the guide pipe 62 through the filter hole 611. The filter hole 611 can filter impurities in the air to prevent them from entering the interior of the slide 2 and causing damage to the electromagnet 3 and other components. The guide pipe 62 introduces air into the interior of the slide 2. The jet component is arranged at the exhaust end of the guide pipe 62, which can spray air in a rotating manner and change the spraying angle to achieve air cooling and heat dissipation of the electromagnet 3, reduce the temperature of the electromagnet 3, and maintain its stable performance.

[0082] Furthermore, the jetting member includes a hollow rotating disk 63 which is in communication with the exhaust end of the guide pipe 62 and is in transmission cooperation with the moving rod 51;

[0083] The hollow turntable 63 is provided with a spray hole 631 which is inclined.

[0084] The hollow turntable 63 is in transmission cooperation with the moving rod 51. The up and down movement of the moving rod 51 drives the hollow turntable 63 to rotate. The nozzle holes 631 opened obliquely on the hollow turntable 63 make the air entering the hollow turntable 63 from the guide tube 62 be ejected at an oblique angle. This oblique ejection method can change the ejection direction of the air, so that the air can more comprehensively cover the surface of the electromagnet 3, enhance the air cooling and heat dissipation effect, and further improve the cooling efficiency of the electromagnet 3.

[0085] When the heavy object moves upward, due to the adsorption of the suction cup 410, the upward movement of the heavy object will drive the box body 42 to move upward, stretching the reciprocating spring 52 to store energy while driving the turntable 61 to rotate through the moving rod 51. The reciprocating spring 52 recovers and also drives the turntable 61 to rotate.

[0086] Furthermore, fan blades are installed inside the hollow turntable 63 to assist in extracting external air (not shown in the figure). Under the action of the fan blades, when the hollow turntable 63 rotates, the rotation of the fan blades can increase the extraction effect of external air to extract it into the slide 2.

[0087] Example 2

[0088] like Figure 7 and Figure 8 As shown, based on the first embodiment, it also includes: a mounting ring 7 is connected to the travel side of the slide 2, and a cover plate 9 is rotatably connected to it through a hinge 8. The center of gravity of the cover plate 9 is located in the lower area, so that the cover plate 9 opens and closes when the slide 2 moves.

[0089] When the slide 2 moves, at the back of the slide 2, since the center of gravity of the cover 9 is located in the lower area, the cover 9 will open and close under the action of inertia and gravity, thereby increasing the effect of air exchange with the outside.

[0090] Working principle:

[0091] Electromagnetic drive: A stable magnetic field is constructed by laying permanent magnets with alternating N and S poles on the linear motor body 1. When the electromagnet 3 in the slide 2 is energized, a current magnetic field is formed according to Ampere's law, which interacts with the magnetic field of the linear motor body 1 to drive the slide 2 to perform linear motion on the linear motor body 1. A time-sharing power-on strategy is adopted to activate the electromagnets 3 in sequence to achieve continuous linear motion of the slide 2.

[0092] Circulation cooling: When a heavy object is placed on the suction cup 410, the load plate 43 is subjected to pressure drop, compressing the return spring 44, and the pressure in the box body 42 increases. The coolant flows into the spiral tube 45 through the liquid inlet pipe 46, and the spiral tube 45 surrounds the outer periphery of the electromagnet 3. After the coolant absorbs the heat generated by the electromagnet 3, it flows back to the cooling water tank 41 in one direction through the one-way discharge pipe 47 under the action of the one-way valve 411. At the same time, the box body 42 passes through the connecting pipe 48, and under the control of the one-way valve 411, the coolant enters the cooling water tank 41 to form a cycle. The heat dissipation fins 49 on the cooling water tank 41 dissipate the heat of the coolant to the surrounding air, accelerating the cooling of the coolant. The two cooling water tanks 41 can be switched for use when the temperature of one of the coolants rises to ensure the cooling effect.

[0093] Energy conversion and air intake and heat dissipation: When a heavy object is placed to cause the box body 42 to drop, the moving rod 51 moves downward accordingly, compressing the reciprocating spring 52 to store elastic potential energy. After the heavy object is removed, the reciprocating spring 52 rebounds, pushing the moving rod 51 to move upward. The moving rod 51 cooperates with the rotating air intake mechanism 6 to drive the rotating air intake mechanism 6 to operate. The turntable 61 rotates, and the outside air enters the guide tube 62 through the filter hole 611. The filter hole 611 filters impurities, and the guide tube 62 introduces air into the interior of the slide 2. The hollow turntable 63 rotates under the drive of the moving rod 51, and air is ejected from its inclined nozzle 631, fully covering the surface of the electromagnet 3 for air cooling and heat dissipation. The fan blades in the hollow turntable 63 can enhance the air extraction effect. In addition, the spoiler 53 on the moving rod 51 stirs the air in the slide 2, speeds up the air flow speed and changes the flow direction, further improving the air cooling and heat dissipation effect.

[0094] Auxiliary heat dissipation: The mounting ring 7 on the moving side of the slide 2 is connected to the cover plate 9 through a hinge 8. The center of gravity of the cover plate 9 is located in the lower area. When the slide 2 moves, under the action of inertia and gravity, the cover plate 9 opens and closes, increasing the exchange effect between the slide 2 and the external air, thereby assisting heat dissipation.

[0095] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
