[0028] With the rapid upgrade and development of the industry, in the field of industrial manufacturing, scenarios with large sizes, long strokes, high loads, and high-precision requirements, such as rocket manufacturing, satellite equipment, automobile assembly, and production of large-scale precision equipment, have emerged rapidly. In the field of automated production, linear motor modules have always won wide favor and large-scale adoption with their high efficiency and precision. However, due to their principles and structural designs, traditional linear motors are prone to problems such as insufficient overall structural strength and reliability of the linear motor module system, which has led to the long-term application of linear motor modules only in scenarios with light loads and short strokes in fields such as 3C, lithium batteries, photovoltaics, and semiconductors, and their technical application potential has not been fully released. Specifically, the root causes of the problem of insufficient reliability include, but are not limited to, the following aspects:

[0029] First, traditional linear motor modules often adopt a system structural design of "the mover on top and the stator at the bottom", resulting in the mover guide rail bearing the double pressure of the load weight and the magnetic interaction force between the mover and the stator, thus causing problems such as excessive load on the guide rail, insufficient structural strength and reliability, and even potential hazards such as frame deformation and accuracy decline after long-term use, making it difficult to adapt to new application scenarios such as long strokes and large loads.

[0030] Second, traditional linear motor modules often adopt non-embedded mover guide rails, and the connection points between the guide rails and the guide rail base frame bear relatively large pressure and / or shear force, further increasing the structural vulnerability of the linear motor module, resulting in insufficient structural strength and reliability of the linear motor module, and causing situations such as insufficient load capacity and high deployment, installation, and maintenance costs.

[0031] To solve the above problems, please refer to Figures 1 to 3 , Figure 1 which is a schematic three-dimensional structure diagram of a linear motor module in an embodiment of this application, Figure 2 which is an exploded structure diagram of the linear motor module in an embodiment of this application, Figure 3 which is a schematic cross-sectional structure diagram of the linear motor module in an embodiment of this application.

[0032] As Figures 1 to 3 shown, an embodiment of the present application provides a linear motor module 100. The linear motor module 100 may include a frame assembly 10, a first mover assembly 20, and a first stator assembly 30. Specifically, the frame assembly 10 may include a first frame 11 and a second frame 12. The first frame 11 may be provided with a mover mounting portion 50, and the second frame 12 may be provided with a stator mounting portion 121. The mover mounting portion 50 may be provided with a plurality of mover guide members, and the mover mounting portion 50 is located below the stator mounting portion 121.

[0033] The first mover assembly 20 may include a first mover body 21, a first load carrier 22, and a first refluxer 23. The first mover body 21 may be disposed on the first load carrier 22 and face the stator mounting portion 121. The first load carrier 22 may be connected to the mover guide members through the first refluxer 23.

[0034] The first stator assembly 30 may include a first stator track 31. The first stator track 31 may be disposed on the stator mounting portion 121 and correspond to the first mover assembly 20. A gap 40 may be provided between the first stator assembly 30 and the first mover assembly 20.

[0035] It can be understood that by adopting the system structure design of "mover below, stator above", and using the upward suction force of the first stator assembly 30 on the first mover assembly 20, the load pressure and friction force of the first mover assembly 20 on the mover guide members can be better reduced, thereby reducing heat generated by friction, improving the operating efficiency of the linear motor module 100, and having a higher load limit compared with the traditional solution without changing the mover guide members, effectively improving the mechanical efficiency, reliability, durability and load capacity.

[0036] It can be further understood that since there is an interaction force between the stator and the mover of the linear motor module 100, in order to avoid the situation that the gap 40 is too small, resulting in cogging force or even mechanical friction and interference due to vibration during the operation of the linear motor module 100, affecting the reliability, stability and control accuracy of the equipment, the minimum value range of the gap 40 may be 0.5 - 5 mm. For example, the minimum value range of the gap 40 may be 0.8 - 1.2 mm.

[0037] It can be understood that in order to enhance the mechanical structure strength, the first frame 11 and the second frame 12 may be formed as two parts of the entire frame to form the frame assembly 10 by an integral molding method, or may be connected in a detachable or fixed manner. And in order to reduce the overall weight of the machine, reduce the magnetic interference of the equipment, improve the stress distribution of components in the scenario of large load and long stroke, and improve the reliability and maintainability of the equipment, at least a part of the frame assembly 10 may be prepared from materials such as carbon fiber resin.

[0038] Please refer to Figures 3 to 5 , Figure 3 which is a schematic cross-sectional structure diagram of a linear motor module in an embodiment of the present application, Figure 4 which is a schematic three-dimensional structure diagram of a mover assembly in an embodiment of the present application, Figure 5 which is a schematic structure diagram of a stator track in an embodiment of the present application.

[0039] In some embodiments, as shown in Figures 3 to 5 , the first mover body 21 may include a plurality of coil windings and / or a plurality of permanent magnets to achieve the driving function of the linear motor module 100. Correspondingly, the first stator track 31 may include a magnetic track; alternatively, the first mover body 21 further includes a coil winding and a permanent magnet, and the first stator track 31 may be provided with a concave-convex structure 33. Among them, the first stator track 31 may be prepared from a magnetic conductive material, specifically including silicon steel sheets, silicon steel alloys or magnetic conductive stainless steel, etc.

[0040] It can be understood that the first stator track 31 may include a magnetic steel piece with a concave-convex structure 33. Since the magnetic steel piece itself does not have magnetism, compared with the stator magnetic track of the traditional linear motor module 100 that stacks a large number of permanent magnets according to magnetic alternation, the production cost is reduced by reducing the number of stator permanent magnets, magnetic interference is reduced, and problems such as external magnetic impurities being adsorbed by the stator can be prevented.

[0041] It can be further understood that in an actual production environment, especially in an environment such as a machining workshop where magnetic debris is easily generated, external impurities such as iron filings, workpieces, and droplets are likely to fall into complex structures such as magnetic tracks and coil windings due to the magnetic force of the module itself, accidental operations, or gravity. On the one hand, it interferes with the electromagnetic system of the linear motor module 100, and on the other hand, it may also affect the reliable and stable operation of mechanical structures such as guide rails, causing potential safety hazards. Therefore, a colloid may also be provided in the mover assembly and / or the stator assembly. By means of potting, injecting glue, etc., a glue layer is formed outside the coil winding and / or the permanent magnet. On the one hand, it ensures the integrity of the assembly, facilitates manufacturing, transportation, installation, disassembly, and maintenance, and prevents iron filings from falling into complex structures that are difficult to clean and maintain during actual production, affecting the reliability of the linear motor module 100.

[0042] Exemplarily, the first mover assembly 20 further includes a first mover colloid 24, the first mover body 21 is disposed in the first mover colloid 24, and at least a part of the first mover body 21 is fixed to the first load rack 22 through the first mover colloid 24; and / or, the first stator assembly 30 may be provided with a first stator colloid 32, and the first stator colloid 32 can cover at least a part of the first stator track 31.

[0043] It can be understood that the first mover body 21 can be completely wrapped by the colloid, or can be partially wrapped by the colloid; the first mover body 21 can also be adhered to the first load carrier 22 by the colloid, and several parts of the first mover body 21 can also be wrapped by multiple colloids respectively. No specific limitation is made here.

[0044] In some embodiments, a placement groove can also be provided on the first load carrier 22, and the coil winding and / or permanent magnet of the first mover body 21 are arranged in the placement groove. On the one hand, it makes it possible to directly pour and inject glue to form the first mover body, saving the mold cost of the traditional pouring and injecting glue work. On the other hand, it can also directly fix multiple faces of the first mover body 21 to the first load carrier 22 through the pouring and injecting glue process, thereby improving the integrity, structural strength and reliability of the first mover assembly 20.

[0045] In some embodiments, the exposure area of the first mover assembly 20 and / or the first stator assembly 30 can also be reduced by providing a dust-proof cover plate, a travel slot, etc. on the frame assembly 10, so as to prevent external impurities such as iron filings, workpieces, and liquid droplets from falling into complex structures such as magnetic rails and coil windings that are difficult to clean and maintain, and improve the reliability of the linear motor module 100.

[0046] It can be understood that the frame assembly 10 can be provided with a dust-proof part 13, and the dust-proof part 13 can cover at least a part of the first frame 11 and / or the first mover assembly 20. The specific form of the dust-proof part 13 can include designs such as a dust-proof cover plate and a travel slot that can play a covering role.

[0047] Exemplarily, the dust-proof part 13 is arranged on the second frame 12, the dust-proof part 13 is provided with a travel space, and at least a part of the first load carrier 22 passes through the travel space.

[0048] Exemplarily, the dust-proof part 13 is arranged on the second frame 12, the dust-proof part 13 corresponds to the first frame 11 and forms a travel space, and at least a part of the first load carrier 22 passes through the travel space.

[0049] Exemplarily, the dust-proof part 13 is arranged on the first frame 11, the dust-proof part 13 is provided with a travel space, and at least a part of the first load carrier 22 passes through the travel space.

[0050] It can be further understood that the travel slot can be separately provided on the first frame 11 or the second frame 12, or can be formed by cooperating with a space provided between the first frame 11 and the second frame 12.

[0051] Please refer to Figure 1 、 Figure 2 and Figure 6 , Figure 1Schematic three-dimensional structure diagram of a linear motor module in an embodiment of the present application, Figure 2 Exploded structure diagram of a linear motor module in an embodiment of the present application, Figure 6 Schematic three-dimensional structure diagram of a first mover assembly and a second mover assembly in an embodiment of the present application.

[0052] In some embodiments, such as Figure 1 、 Figure 2 and Figure 6 shown, the first mover assembly 20 may include a first mover body 21, a first load rack 22 and a first refluxer 23. The first mover body 21 is disposed on the first load rack 22 and faces the stator mounting portion 121. The first load rack 22 is connected to the mover guide member through the first refluxer 23.

[0053] It can be understood that traditional linear motor modules 100 often adopt a design in which the mover is connected to the guide rail through a single refluxer. Although this can save costs, it limits the structural strength and reliability of the linear motor module 100. Especially when affected by vibration, high load and / or external impact, and when the linear motor module 100 is in a high-speed running state, the connection between the refluxer and the guide rail is likely to be blocked or jammed, reducing the load potential of the linear motor module 100. Therefore, a plurality of refluxers may be provided on the load rack corresponding to the mover guide member to increase the number of contact surfaces through the plurality of refluxers, thereby achieving the effects of sharing the load, dispersing stress and providing redundancy, and reducing the cumulative error caused by installation, vibration or impact, etc., further improving the reliability of the linear motor module 100. For example, a plurality of first refluxers 23 are provided on the same side of the first load rack 22, and the first load rack 22 is connected to the mover guide member through the plurality of first refluxers 23.

[0054] Since the linear motor module 100 can reach a relatively high running speed during operation, in order to prevent or alleviate collision problems caused by reasons such as misoperation by production personnel, debugging errors or program failures, and reduce safety risks, not only can the relevant design of the refluxer be used to improve the robustness of the linear motor module 100 to vibration and impact, but also hard limiting, soft limiting or a combination of hard and soft limiting methods can be used for limiting to further improve the reliability of the linear motor module 100.

[0055] In some embodiments, such as Figure 1 、 Figure 2 and Figure 6As shown, a magnetic scale 61 can be arranged along the guide rail direction of the mover guide rail member on the frame assembly 10, and a magnetic scale reading head 62 can be arranged on the first mover assembly 20. The position and / or speed condition of the current mover assembly can be obtained by setting the magnetic scale 61 and the magnetic scale reading head 62, and then the host or a control unit such as a PLC is used to judge whether the stop or deceleration condition is met, so as to realize the function of soft limit. The running accuracy of the linear motor module 100 can also be further improved through the position and / or speed condition of the current mover assembly, reducing the position and speed errors and meeting the process requirements of higher precision.

[0056] In some embodiments, a photoelectric induction member 63 can be arranged on one of the frame assembly 10 and the first mover assembly 20, and a photoelectric sensor 64 can be arranged on the other. The position and / or speed condition of the current mover assembly is obtained through the photoelectric induction member 63 - photoelectric sensor 64 scheme, and then the host or a control unit such as a PLC is used to judge whether the stop or deceleration condition is met, so as to realize the function of soft limit. The photoelectric induction member 63 - photoelectric sensor 64 scheme includes a photoelectric film - photoelectric switch scheme with relatively low cost, and can directly monitor whether the equipment reaches a certain position. Moreover, since the photoelectric film or the photoelectric switch can be arranged on the outer periphery of the frame assembly 10, once a device failure occurs or the device needs to be charged or replaced, maintenance and repair can be carried out without disassembling the frame assembly 10, reducing the maintenance cost.

[0057] In some embodiments, a stopper 65 can be arranged at the end of the guide rail stroke of the mover guide rail member on the frame assembly 10. Among them, the stopper 65 can include buffer devices such as a rubber buffer seat, a buffer pad, and a spring. Through mechanical buffering, the damage to the internal mechanical structure of the linear motor module 100 caused by accidental impact or vibration is reduced, and the reliability of the linear motor module 100 is improved.

[0058] In some embodiments, a cover plate 83 can also be arranged at the end of the guide rail stroke of the mover guide rail member, which is not only convenient for installing the stopper 65, but also can prevent external impurities from floating to the mover guide rail member from the end of the guide rail stroke, affecting the safe and stable operation of the linear motor module 100, thereby further improving the reliability of the linear motor module 100.

[0059] It can be understood that the design of the mechanical structure, material selection, electromagnetic field distribution, etc. of the local components of the linear motor module 100 will also affect the overall reliability of the linear motor module 100.

[0060] Traditional linear motor modules 100 often adopt a single power mode, resulting in the linear motor module 100 having difficulty in large-load and long-stroke application scenarios. The power of a single mover is too high, which affects the reliability of the overall linear motor module 100 in terms of heat dissipation. Technical effects such as sharing the weight and improving the load and transportation capacity of the device can be achieved by setting up a second parallel power source or other means.

[0061] Please refer to Figure 2 and Figure 3 , Figure 2 , which is an exploded structural schematic diagram of the linear motor module in an embodiment of the present application. Figure 3 And

[0062] In some embodiments, as shown in Figure 2 and Figure 3 , the first frame 11 may be provided with a first support portion 141, the second frame 12 may be provided with a second support portion 142, and the first support portion 141 may be connected to the second support portion 142 to form a support central axis 14. The linear motor module 100 includes a second stator assembly 82 and a second mover assembly 81. The second stator assembly 82 corresponds to the first stator assembly 30 with respect to the support central axis 14, and the second mover assembly 81 corresponds to the first mover assembly 20 with respect to the support central axis 14.

[0063] Specifically, the first support portion 141 may be connected to the second support portion 142 by means of a dovetail groove, a T-shaped groove, a C-shaped groove, a U-shaped groove, or an I-shaped groove, etc., or may also be connected by means of threads, clamping, riveting, or welding.

[0064] Specifically, the second stator assembly 82 is symmetric with the first stator assembly 30 with respect to the support central axis 14, and the second mover assembly 81 is symmetric with the first mover assembly 20 with respect to the support central axis 14. Among them, the second mover assembly 81 may further include a second load frame, and the second load frame may be connected to the first load frame 22 to form a load group frame.

[0065] It can be understood that the load group frame may be integrally formed with the second load frame and the first load frame 22 as two parts of the load group frame, or may be detachably connected or fixedly connected by the second load frame and the first load frame 22. By correspondingly setting or even symmetrically setting two power sources, the propulsion and load capacity of the linear motor module 100 are improved, the upper limits of the load and thrust are increased, and the operating reliability of the linear motor module 100 is improved.

[0066] It can be further understood that, when necessary, the first mover component 20 and the second mover component 81 can also be separated and operated independently, so as to improve the space utilization rate of unit production capacity, reduce the costs of supporting equipment such as unit production capacity control and communication, not only improve the design and use flexibility of the linear motor module 100, but also balance the load on both sides, and further improve the reliability of the linear motor module 100.

[0067] Since the traditional stator mounting part 121 is generally arranged on the base frame below the mover, only fixing screw holes are often designed, and it is not considered that the strength of the connection between the stator mounting part 121 and the stator may be affected due to the interaction force between the mover and the stator when the stator is mounted above. Therefore, the stator mounting part 121 can be recessed in the upper frame body, so that after processes such as colloid pouring are completed for the stator, it can maintain a closer connection or even integration with the upper frame body, so as to further enhance the fastening of the stator, and by reducing the geometric complexity of the structure, optimize the structural stress distribution of the upper frame body, improve the mechanical structure strength, and thus improve the overall reliability of the linear motor module 100.

[0068] In some embodiments, a slot or a hollow 70 can also be provided in the first frame body 11; and / or at least a part of the frame body assembly 10 is made of materials such as carbon fiber resin, so as to achieve the effects of reducing weight, saving materials, and also can produce the effects of improving stress distribution, enhancing mechanical structure strength, and improving reliability.

[0069] In some embodiments, a plurality of mover guide members can be provided in the mover mounting part 50 of the first frame body 11 to further share the load pressure, improve the reliability of the linear motor module 100, and also reduce the risk of shear force damage at the connection between the mover guide member and the base frame by inlaying the mover guide member on the surface of the base frame (which can be used as the first frame body 11), improve the mechanical structure strength, and enhance the load capacity and reliability of the linear motor module 100. Among them, the mover guide member can be detachably installed / fixedly installed on the surface of the base frame, or can also be directly opened in the mover mounting part 50, or can be used as an independent component and integrally formed with the first frame body 11 after being installed on the surface of the first frame body 11.

[0070] Specifically, the mover mounting part 50 can include a first side 51 and a second side 52 that are parallel to each other. The mover mounting part 50 can be provided with at least a first mover guide member 53 and a second mover guide member 54. The first mover guide member 53 is inlaid on the first side 51, and the second mover guide member 54 is inlaid on the second side 52.

[0071] Please refer to Figure 6 , Figure 6 which is a three-dimensional structural schematic diagram of the first mover component and the second mover component in an embodiment of the present application.

[0072] Further, as Figure 2 , Figure 3 and Figure 6 shown, the first mover guide member 53 can be at least partially correspondingly arranged with the second mover guide member 54. For example, the load-bearing direction of the first mover guide member 53 can be made opposite to the load-bearing direction of the second mover guide member 54, and correspondingly, the directions of the first returners 23 on both sides are made opposite to each other, and the first mover assembly 20 is restrictively arranged on the guide rail to ensure the contact tightness between the guide rail and the mover assembly, reduce the risk of derailment, and improve the reliability of the linear motor module 100; or, the load-bearing direction of the first mover guide member 53 can be made opposite to the load-bearing direction of the second mover guide member 54, and correspondingly, the directions of the first returners 23 on both sides are made opposite to each other, which can also play a role in restrictively arranging the first mover assembly 20 on the guide rail, thereby ensuring the contact tightness between the guide rail and the mover assembly, reducing the risk of derailment, and improving the reliability of the linear motor module 100.

[0073] Please refer to Figure 7 , Figure 7 , which is a schematic structural diagram of the linear motor module in an embodiment of the present application. As Figure 7 shown, in practical applications, since the overall reliability and mechanical structure strength of the linear motor module 100 can be guaranteed, its overall stroke can be appropriately increased to meet various application scenarios with long strokes and large loads.

[0074] The embodiment of the present application also proposes an electromechanical device, which can include the linear motor module 100 in any embodiment of the present application.
