[0018] With the rapid upgrading and development of the industry, scenarios with large size, long stroke, high load and high precision requirements such as rocket manufacturing, satellite equipment, automobile assembly and large precision equipment production have emerged rapidly in the field of industrial manufacturing. In the field of automated production, linear motor modules have always won wide favor and large-scale adoption for their high efficiency and precision. However, traditional linear motors are subject to their principles and structural design, which easily leads to the problem of insufficient overall structural strength and reliability of the linear motor module system. As a result, linear motor modules can only be used in scenarios with lighter loads and shorter strokes in the fields of 3C, lithium batteries, photovoltaics, semiconductors, etc. for a long time, and have failed to fully release their technical application potential. Specifically, the root causes of the problem of insufficient reliability include but are not limited to the following aspects: First, traditional linear motor modules often adopt a system structure design of "motor on top and stator on the bottom", which causes the mover guide rail to bear the dual pressure of load weight and mover-stator magnetic interaction force, resulting in problems such as excessive guide rail load, insufficient structural strength and reliability. Long-term use may even easily cause dangerous hidden dangers such as frame deformation and reduced accuracy, making it difficult to adapt to new application scenarios such as long stroke and large load.

[0019] Second, traditional linear motor modules often use non-embedded mover guides. The connection points between the guides and the guide bases are subject to greater pressure and / or shear force, further increasing the structural fragility of the linear motor modules, resulting in insufficient structural strength and reliability, insufficient load capacity, and high deployment, installation, and maintenance costs.

[0020] To solve the above problems, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the three-dimensional structure of a linear motor module in an embodiment of the present application. Figure 2 This is a schematic diagram of the structure explosion of a linear motor module in one embodiment of the present application. Figure 3 It is a schematic diagram of the cross-sectional structure of a linear motor module in one embodiment of the present application.

[0021] like Figures 1 to 3 As shown, the embodiment of the present application proposes 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, 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 rails, and the mover mounting portion 50 is located below the stator mounting portion 121.

[0022] The first mover assembly 20 may include a first mover body 21 , a first load frame 22 and a first returner 23 . The first mover body 21 may be disposed on the first load frame 22 and facing the stator mounting portion 121 . The first load frame 22 may be connected to the mover guide rail member through the first returner 23 .

[0023] The first stator assembly 30 may include a first stator rail 31 . The first stator rail 31 may be disposed at the stator mounting portion 121 and correspond to the first mover assembly 20 . A gap 40 may be disposed between the first stator assembly 30 and the first mover assembly 20 .

[0024] It can be understood that by adopting the system structure design of "mover at the bottom and stator at the top" and utilizing the upward suction force of the first stator component 30 on the first mover component 20, the load pressure and friction force of the first mover component 20 on the mover guide rail can be better reduced, thereby reducing frictional heat and improving the operating efficiency of the linear motor module 100. In addition, compared with traditional solutions, the mechanical efficiency, reliability, durability and load capacity can be effectively improved while the mover guide rail remains unchanged.

[0025] It can be further understood that, due to the interaction force between the stator and the mover of the linear motor module 100, in order to avoid the gap 40 being too small, generating toothing force during the operation of the linear motor module 100, or even causing mechanical friction and interference due to vibration, which affects the reliability, stability and control accuracy of the equipment, the minimum value of the gap 40 can be in the range of 0.5-5mm. For example, the minimum value of the gap 40 can be in the range of 0.8-1.2mm.

[0026] It is understandable that, in order to enhance the strength of the mechanical structure, the first frame 11 and the second frame 12 can be formed as two parts of the entire frame by an integral molding method to form a frame assembly 10, or can be connected in a detachable or fixed manner. In addition, in order to reduce the weight of the entire machine, reduce the magnetic interference of the equipment, improve the stress distribution of the 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 can be made of materials such as carbon fiber.

[0027] See also Figures 3 to 5 , Figure 3 This is a schematic cross-sectional view of a linear motor module in an embodiment of the present application. Figure 4 Schematic diagram of the three-dimensional structure of the moving subassembly in one embodiment of the present application. Figure 5 Schematic diagram of the structure of the stator track in one embodiment of the present application.

[0028] In some embodiments, Figures 3 to 5 As shown, the first mover body 21 may include multiple coil windings and / or multiple permanent magnets to realize the driving function of the linear motor module 100. Correspondingly, the first stator track 31 may include a magnetic track; or, the first mover body 21 also includes coil windings and permanent magnets, and the first stator track 31 may be provided with a concave-convex structure 33. Among them, the first stator track 31 may be made of magnetic conductive material, specifically silicon steel sheet, silicon steel alloy or magnetic conductive stainless steel.

[0029] It can be understood that the first stator track 31 may include a magnetic steel part with a concave-convex structure 33. Since the magnetic steel part itself is not magnetic, compared with the stator magnetic track adopted by the traditional linear motor module 100 which stacks a large number of permanent magnets based on magnetic interlacing, the production cost is reduced by reducing the number of stator permanent magnets, magnetic interference is reduced, and external magnetic impurities can be prevented from being adsorbed by the stator.

[0030] It can be further understood that in actual production environments, especially in environments such as machine shops where magnetic debris is easily generated, external impurities such as iron filings, workpieces, and droplets are easily affected by the magnetic force of the module itself, accidental operation, or gravity and fall into complex structures such as magnetic rails and coil windings that are difficult to clean and maintain. 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 safety hazards. Therefore, a colloid can also be provided in the mover assembly and / or the stator assembly, and a glue layer is formed on the outside of the coil winding and / or the permanent magnet by means of glue pouring, glue injection, etc., which 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 in actual production, affecting the reliability of the linear motor module 100.

[0031] Exemplarily, the first mover assembly 20 also includes a first mover colloid 24, the first mover body 21 is arranged on the first mover colloid 24, and at least a portion of the first mover body 21 is fixed to the first load frame 22 through the first mover colloid 24; and / or, the first stator assembly 30 can be provided with a first stator colloid 32, and the first stator colloid 32 can cover at least a portion of the first stator track 31.

[0032] It is understandable that the first mover body 21 can be completely wrapped with colloid, or partially wrapped with colloid; the first mover body 21 can also be bonded to the first load frame 22 with colloid, or several parts of the first mover body 21 can be respectively wrapped with multiple colloids. No specific limitation is given here.

[0033] In some embodiments, a placement groove may be provided on the first load frame 22, and the coil winding and / or permanent magnet of the first mover body 21 may be placed in the placement groove. On the one hand, it is possible to directly form the first mover body by glue pouring and injection, saving the mold cost of traditional glue pouring and injection work, and on the other hand, multiple surfaces of the first mover body 21 can be directly fixed to the first load frame 22 by glue pouring and injection process, thereby improving the integrity, structural strength and reliability of the first mover assembly 20.

[0034] In some embodiments, the exposed area of ​​the first mover assembly 20 and / or the first stator assembly 30 can be reduced by providing dust shields, travel slots, etc. on the frame assembly 10, thereby preventing 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, thereby improving the reliability of the linear motor module 100.

[0035] It is understandable that the frame assembly 10 may be provided with a dustproof portion 13, which can cover at least a portion of the first frame 11 and / or the first mover assembly 20. The specific form of the dustproof portion 13 may include a dustproof shield, a travel slot, and other designs that can play a covering role.

[0036] Exemplarily, the dustproof portion 13 is disposed on the second frame body 12 , and a travel space is defined in the dustproof portion 13 , and at least a portion of the first load frame 22 passes through the travel space.

[0037] Exemplarily, the dustproof portion 13 is disposed on the second frame 12 , the dustproof portion 13 corresponds to the first frame 11 , and forms a travel space, and at least a portion of the first load frame 22 passes through the travel space.

[0038] Exemplarily, the dustproof portion 13 is disposed on the first frame body 11 , and a travel space is defined in the dustproof portion 13 , and at least a portion of the first load frame 22 passes through the travel space.

[0039] It can be further understood that the travel slot can be provided separately on the first frame 11 or the second frame 12 , or can be formed by providing a space between the first frame 11 and the second frame 12 .

[0040] See also Figure 1 , Figure 2 and Figure 6 , Figure 1This is a schematic diagram of the three-dimensional structure of a linear motor module in an embodiment of the present application. Figure 2 This is a schematic diagram of the structure explosion of a linear motor module in one embodiment of the present application. Figure 6 It is a schematic diagram of the three-dimensional structure of the first mover assembly and the second mover assembly in one embodiment of the present application.

[0041] In some embodiments, Figure 1 , Figure 2 and Figure 6 As shown, the first mover assembly 20 may include a first mover body 21 , a first load frame 22 and a first returner 23 . The first mover body 21 is disposed on the first load frame 22 and faces the stator mounting portion 121 . The first load frame 22 is connected to the mover guide rail member through the first returner 23 .

[0042] It is understandable that the conventional linear motor module 100 often adopts a design in which the mover is connected to the guide rail through a single returner. Although this can save costs, it limits the structural strength and reliability of the linear motor module 100. In particular, when the linear motor module 100 is subjected to vibration, high load and / or external impact, and when the linear motor module 100 is running at high speed, the returner and the guide rail are prone to poor connection, stuck and unable to move, etc., which reduces the load potential of the linear motor module 100. Therefore, the load frame can be provided with multiple returners corresponding to the mover guide rail member, and the number of contact surfaces is expanded by multiple returners, thereby generating the effects of sharing the load, dispersing stress and providing redundancy, and reducing the cumulative errors caused by installation, vibration or impact, etc., and further improving the reliability of the linear motor module 100. For example, multiple first returners 23 are provided on the same side of the first load frame 22, so that the first load frame 22 is connected to the mover guide rail member through multiple first returners 23.

[0043] Since the linear motor module 100 can reach a relatively high operating speed during operation, in order to prevent or alleviate collision problems caused by production personnel's misoperation, debugging errors or program failures, and reduce safety risks, not only can the robustness of the linear motor module 100 against vibration and impact be improved through the relevant design of the return device, but also hard limit, soft limit or a combination of hard and soft limit can be used to further improve the reliability of the linear motor module 100.

[0044] In some embodiments, Figure 1 , Figure 2 and Figure 6As shown, the frame assembly 10 can be provided with a magnetic scale 61 along the guide rail direction of the movable guide rail member, and the first movable assembly 20 can be provided with a magnetic scale reading head 62. The current position and / or speed of the movable assembly can be obtained by setting the magnetic scale 61 and the magnetic scale reading head 62, and then the host or PLC and other control units can be used to determine whether the stop or deceleration conditions are met, thereby realizing the function of soft limit. The operation accuracy of the linear motor module 100 can also be further improved through the current position and / or speed of the movable assembly, reducing position and speed errors and meeting higher precision process requirements.

[0045] In some embodiments, one of the frame assembly 10 and the first mover assembly 20 may be provided with a photoelectric sensing element 63, and the other may be provided with a photoelectric sensor 64. The current position and / or speed of the mover assembly is obtained through the scheme of the photoelectric sensing element 63-photoelectric sensor 64, and then the host or control unit such as PLC is used to determine whether the stop or deceleration conditions are met, thereby realizing the function of soft limit. The scheme of the photoelectric sensing element 63-photoelectric sensor 64 includes a low-cost photoelectric sheet-photoelectric switch scheme, which can directly monitor whether the equipment has reached a certain position. In addition, since the photoelectric sheet or photoelectric switch can be set on the outer peripheral side of the frame assembly 10, once a device failure occurs or the equipment needs to be charged or replaced, maintenance and warranty can be carried out without disassembling the frame assembly 10, reducing maintenance costs.

[0046] In some embodiments, the frame assembly 10 may be provided with a limiter 65 at the end of the guide rail travel of the movable guide rail member. The limiter 65 may include a rubber buffer seat, a buffer pad, a spring and other buffering devices. 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.

[0047] In some embodiments, a cover plate 83 can be provided at the end of the guide rail stroke of the movable guide rail member, which not only facilitates the installation of the limiter 65, but also prevents external impurities from floating from the end of the guide rail stroke to the movable guide rail member and affecting the safe and stable operation of the linear motor module 100, thereby further improving the reliability of the linear motor module 100.

[0048] It is understandable 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 .

[0049] Traditional linear motor modules 100 often use a single power mode, which makes it difficult for the linear motor module 100 to handle large loads and long strokes. The power of a single mover is too high, which affects the reliability of the entire linear motor module 100 in terms of heat dissipation. By setting a second parallel power, the technical effect of sharing weight and improving the load and transportation capacity of the equipment can be achieved.

[0050] See also Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure explosion of a linear motor module in one embodiment of the present application. Figure 3 It is a schematic diagram of the cross-sectional structure of a linear motor module in one embodiment of the present application.

[0051] In some embodiments, Figure 2 and Figure 3 As shown, the first frame 11 can be provided with a first support portion 141, the second frame 12 can be provided with a second support portion 142, the first support portion 141 can 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.

[0052] Specifically, the first support portion 141 can be connected to the second support portion 142 by means of a dovetail groove, a T-slot, a C-slot, a U-slot or an I-slot, or by means of threads, snap-fitting, riveting or welding.

[0053] Specifically, the second stator assembly 82 is symmetrical with the first stator assembly 30 about the support center axis 14, and the second mover assembly 81 is symmetrical with the first mover assembly 20 about the support center axis 14, wherein the second mover assembly 81 may also include a second load frame, and the second load frame may be connected to the first load frame 22 to form a load assembly frame.

[0054] It is understandable that the load assembly frame can be formed by integrating the second load frame and the first load frame 22 as two parts of the load assembly frame, or the second load frame and the first load frame 22 can be detachably connected or fixedly connected. By correspondingly or even symmetrically arranging two power sources, the propulsion and load capacity of the linear motor module 100 are improved, the load and thrust upper limits are increased, and the operating reliability of the linear motor module 100 is improved.

[0055] It can be further understood that, when necessary, the first mover assembly 20 and the second mover assembly 81 can be operated separately, thereby improving the space utilization rate of unit production capacity and reducing the cost of supporting equipment such as unit production capacity control and communication. This not only improves the design and use flexibility of the linear motor module 100, but also balances the load on both sides, further improving the reliability of the linear motor module 100.

[0056] The conventional stator mounting part 121 is generally arranged on the base frame below the mover, and is often only designed with fixing screw holes, without considering 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 installed on the upper part. Therefore, the stator mounting part 121 can be recessed in the upper frame, so that the stator can maintain a closer connection with the upper frame or even be integrated after the colloid casting and other processes are completed, so as to further enhance the tightness of the stator, and by reducing the geometric complexity of the structure, optimize the structural stress distribution of the upper frame, and improve the mechanical structure strength, thereby improving the overall reliability of the linear motor module 100.

[0057] In some embodiments, a slot or hollow 70 may be provided in the first frame 11; and / or at least a portion of the frame assembly 10 may be made of materials such as carbon fiber, so as to reduce weight and save materials, and also improve stress distribution, enhance mechanical structure strength, and improve reliability.

[0058] In some embodiments, a plurality of movable guide rails can be provided on the movable mounting portion 50 of the first frame 11 to further share the load pressure and improve the reliability of the linear motor module 100. The movable guide rails can also be embedded on the surface of the base frame (which can be used as the first frame 11) to reduce the risk of shear damage at the connection between the movable guide rails and the base frame, improve the strength of the mechanical structure, and enhance the load capacity and reliability of the linear motor module 100. The movable guide rails can be detachably mounted / fixedly mounted on the surface of the base frame, can be directly opened on the movable mounting portion 50, or can be installed on the surface of the first frame 11 as an independent component and integrated with the first frame 11.

[0059] Specifically, the mover mounting portion 50 may include a first side 51 and a second side 52 which are parallel to each other. The mover mounting portion 50 may be provided with at least a first mover guide member 53 and a second mover guide member 54. The first side 51 is embedded with the first mover guide member 53, and the second side 52 is embedded with the second mover guide member 54.

[0060] See also Figure 6 , Figure 6 It is a schematic diagram of the three-dimensional structure of the first mover assembly and the second mover assembly in one embodiment of the present application.

[0061] Further, such as Figure 2 , Figure 3 and Figure 6 As shown, the first movable guide rail member 53 can be at least partially arranged to correspond to the second movable guide rail member 54. For example, the load-bearing direction of the first movable guide rail member 53 can be opposite to the load-bearing direction of the second movable guide rail member 54, and the first returners 23 on both sides are opposite to each other, so that the first movable subassembly 20 is restrictively arranged on the guide rail, ensuring the contact tightness between the guide rail and the movable subassembly, reducing the risk of derailment, and improving the reliability of the linear motor module 100; or, the load-bearing direction of the first movable guide rail member 53 can be opposite to the load-bearing direction of the second movable guide rail member 54, and the first returners 23 on both sides are opposite to each other, which can also play the role of restrictively arranging the first movable subassembly 20 on the guide rail, thereby ensuring the contact tightness between the guide rail and the movable subassembly, reducing the risk of derailment, and improving the reliability of the linear motor module 100.
