[0014] Preferably, the support platform can be moved by means of a lever drive via a drive seat.

[0015] The advantages of the splicing linear motor module proposed in this invention are as follows:

[0016] 1. Through the detachable insertion design of the interface between the first adapter and the slide rail body, multiple sections of the slide rail body can be freely spliced ​​according to the distance requirements of the actual application scenario, without the need for customized fixed-length integrated modules, which greatly reduces the equipment procurement and replacement costs and is suitable for different scenarios from short-distance precision transmission to long-distance conveying; the magnetic grooves of the slide rail body are arranged according to the magnetic pole pattern, and the magnet body is fixed by the first bolt. After splicing, the magnets at the joint can still maintain a continuous alternating arrangement, avoiding the magnetic interruption or disorder caused by the docking deviation of traditional splicing modules, and ensuring the stability of magnetic transmission; the screw lever is detachably connected to the sleeve and the torque port of the motor drive end through the connector, and the external thread fit can be adjusted by the equidistant torque port, which can accurately match the splicing length of the slide rail body, realize the synchronous adaptation of the screw drive and the slide rail length, and solve the problem of asynchronous splicing of traditional transmission components and slide rails.

[0017] 2. Compatible with three sports modes, greatly improving practicality:

[0018] Magnetic drive mode: The magnetic moving body of the moving structure and the magnetic body of the sliding structure cooperate through magnetic force to achieve contactless high-speed response movement, which is suitable for scenarios with high requirements for motion accuracy and response speed and low load (such as electronic component assembly).

[0019] Belt drive mode: The conveyor belt of the guide structure forms a stable transmission through guide rollers, the first motor and pulleys. The moving seat is fitted with the conveyor belt through the second guide and fixed by the lower screw and pressure cap, realizing a linear movement with stronger load capacity. It is suitable for material conveying scenarios with medium and low precision and large load (such as logistics sorting).

[0020] Lead screw drive mode: The lead screw of the transmission structure is engaged with the screw of the drive seat, and high-precision linear motion is achieved by the second motor. It is suitable for scenarios with extremely high requirements for positioning accuracy and motion stability (such as machine tool processing and precision testing).

[0021] The three motion modes can be quickly switched through the detachable connection of components. There is no need to modify the entire module. Only the connection between the moving structure, the guiding structure and the transmission structure needs to be adjusted to adapt to different working conditions and improve the equipment reuse rate.

[0022] 3. The support platforms can be symmetrically arranged on the upper and lower sides of the slide rail body. The guiding structure achieves stable support through the L-shaped guide frame and the second adapter seat, breaking the limitation that traditional modules can only be arranged on one side, making full use of space, and is especially suitable for scenarios with compact equipment layout (such as dense workstations in automated production lines). The support platforms on the upper and lower sides can adopt different motion modes (such as magnetic transmission on one side and screw transmission on the other side), or move in the same direction or in opposite directions simultaneously, to achieve double-sided staggered operation, improve the efficiency of operation per unit time, and meet the production needs of multiple processes in parallel.

[0023] 4. From light-load, high-precision magnetic drive to heavy-load, medium-precision belt drive, and heavy-load, high-precision ball screw drive, these three modes cover different load (light, medium, heavy) and precision (low, medium, high) requirements, and can be applied to multiple fields such as automated production, intelligent manufacturing, and precision machinery. If the motion stroke needs to be extended, only the slide rail body, ball screw lever, and conveyor belt splicing section need to be added. If a new motion mode needs to be added, only the corresponding transmission components need to be added (such as adding a ball screw drive, only a second motor, ball screw lever, and drive seat need to be added), without replacing the core components of the module, resulting in low expansion costs.

[0035] As a further embodiment of the present invention, the sliding structure 1 includes a slide rail body 11, a plurality of first bolts 12, a plurality of magnet bodies 13, and a plurality of first adapter seats 14.

Interfaces 17 are symmetrically provided on the left and right side walls of the slide rail body 11, and the interface 17 is near the front and rear ends. A plurality of first bolts 12 respectively movably pass through the countersunk holes. A plurality of magnet bodies 13 respectively movably pass through the middle of the magnetic grooves 15, and the magnet bodies 13 are fixed by the first bolts 12. A plurality of magnets are located in the magnetic grooves 15 and arranged according to magnetic poles. The two ends of the plurality of first adapter seats 14 are respectively detachably inserted into the interface 17 at both ends of the slide rail body 11, and the first adapter seats 14 are used for the slide rail bodies 11 to connect with each other.

[0036] More specifically, the distance between the magnetic grooves 15 at both ends of the slide rail body 11 and the side walls at both ends of the slide rail body 11 is half the distance between the two magnetic grooves 15, thereby ensuring that the distance between the two magnetic bodies 13 at both ends of the slide rail body 11 remains consistent after docking; the sliding structure 1 is the core bearing and splicing foundation of the splicing linear motor module, realizing the mutual docking of multiple slide rail bodies 11, used to support the moving structure 3, and at the same time, the free splicing is realized through the docking design of the first adapter seat 14, and the guide groove 16 ensures the smooth guidance of the moving structure 3.

[0037] As a further embodiment of the present invention, the guiding structure 2 includes a pair of guiding frames 20, two pairs of roller frames 21, two pairs of guide rollers 22, a second adapter seat 23, a first bearing 24, a second bearing 25, a conveyor belt 26, a first motor 27, a pair of pulleys 28, and a transmission belt 29; both pairs of guiding frames 20 are L-shaped, and a roller groove is provided near the middle of one end of each pair of guiding frames 20, and a first guide opening 5 communicating with the front side wall of the guiding frame 20 is opened on the front side of the roller groove. One end of each pair of guiding frames 20 is detachably mounted on both ends of the slide rail body 11, and one of the guiding frames 20 has an installation groove 9 on its side wall. The two pairs of roller frames 21 are symmetrically arranged on the upper wall of one end of each guiding frame 20, and the two pairs of guide rollers 22 are movably embedded between the other ends of the roller frames 21 and movably embedded in the roller groove, and the roller shaft in the middle of the guide roller 22 is movable. The second adapter 23 is symmetrically arranged on one side wall of the guide frame 20, and the second adapter 23 is detachably connected to the interface 17 of the slide rail body 11. The first bearing 24 is fixedly embedded in the middle of the other guide frame 20, and the second bearing 25 is fixedly embedded in the middle of one of the guide frames 20. The second bearing 25 is located above the mounting groove 9. The inner ring of the middle of the second bearing 25 is symmetrically provided with a through torque port 7. The conveyor belt 26 is detachably mounted on the guide roller 22 and passes through the first guide port 5 and the roller groove. The first motor 27 is fixedly arranged on the upper wall of the other end of one of the guide frames 20. A pair of pulleys 28 are fixedly arranged on the drive end of the first motor 27 and the roller shaft of one of the guide rollers 22, respectively. The transmission belt 29 is movably mounted between the pulleys 28.

[0038] The guide structure 2, through its detachable connection design, not only achieves flexible assembly and disassembly with the sliding structure 1, but also forms a stable belt drive through the cooperation of the transmission components related to the guide roller 22, the conveyor belt 26 and the first motor 27. At the same time, it provides support for the assembly of the transmission structure 4 with the help of the first bearing 24 and the second bearing 25, thus integrating the support function, belt drive function and screw drive adaptation function, adapting to the multi-scenario application needs of the module.

[0039] As a further embodiment of the present invention, the movable structure 3 includes a movable seat 31, a plurality of second bolts 32, a magnetic movable body 33, a plurality of pressing screws 34, and a plurality of pressure caps 35; the movable seat 31 is rectangular, and a T-shaped sleeve 36 is provided in the middle of the lower wall of the movable seat 31. The movable seat 31 is movably fitted onto the slide rail body 11 through the sleeve 36, and both ends of the lower wall of the movable seat 31 can be inserted into the guide groove 16. A through mounting cavity 38 is provided in the middle of the top of the movable seat 31, and the lower wall of the mounting cavity 38 is provided with a cavity communicating with the sleeve 36. The force-receiving port 37 and the bottom of the front side wall of the mounting cavity 38 are provided with a second guide port 6. Several second bolts 32 are respectively screwed to the front and rear side walls of the movable seat 31, and the second bolts 32 are connected to the mounting cavity 38. The magnetic movable body 33 is movably embedded in the mounting cavity 38 and can be fixed by the second bolts 32. The lower wall of the magnetic movable body 33 is provided with a magnetic structure corresponding to the magnet body 13. Several pressing screws 34 are respectively movably inserted through the upper walls of the left and right ends of the mounting cavity 38, and several pressure caps 35 are respectively movably fitted on the pressing screws 34.

[0040] This mobile structure 3, through its detachable assembly and multi-interface adaptation design, achieves flexible compatibility with both magnetic drive and belt drive modes. It does not require structural modification of the mobile base 31 itself; the transmission mode can be switched simply by adjusting the assembly method of the components within the mounting cavity 38, adapting to the motion requirements of different scenarios. At the same time, with the cooperation of the guide groove 16 and the sleeve 36, the stability and accuracy of the motion process are ensured, providing core support for the multi-scenario application of the module.

[0041] As a further embodiment of the present invention, the transmission structure 4 includes a support platform 41, a second motor 42, a sleeve 43, a lever 44, and a drive seat 45. One end of the support platform 41 is detachably inserted into the mounting groove 9 of the guide frame 20. The second guide port 6 of the support platform 41 can be fitted onto the conveyor belt 26, and the conveyor belt 26 is clamped and fixed by the pressure cap 35 driven by the pressing screw 34. The support platform 41 can be symmetrically arranged on the upper and lower sides of the slide rail body 11, and the support platform 41 can be moved by the conveyor belt 26 or the magnetic moving body 33. The second motor 42 is fixedly installed in the middle of the upper wall of the support platform 41, and the driving end of the second motor 42 moves through the middle of the second bearing 25. The upper and lower side walls of the driving end of the second motor 42 are provided with torque blocks that fit with the torque port 7 of the second bearing 25. One end of the sleeve 43 is fixedly inserted into the middle of the first bearing 24, and the inner side wall of the sleeve 43 is equidistant. The lever 44 has several torque ports 7 identical to those of the second bearing 25. One end of the lever 44 has a connector 8 that matches the torque port 7 on the inner wall of the sleeve 43. The other end of the lever 44 has several torque ports 7 identical to those on the inner wall of the sleeve 43. One end of the lever 44 is detachably inserted into the sleeve 43 via the connector 8, and the other end of the lever 44 is connected to the drive end of the second motor 42 via the torque port 7. The drive seat 45 is concave, and a spiral hole that matches the lever 44 is provided in the middle of the drive seat 45. Both ends of the drive seat 45 are detachably mounted on the front and rear side walls of the support platform 41 via bolts. The spiral hole of the drive seat 45 is movably screwed onto the lever 44. The support platform 41 can move by means of the lever 44 through the drive seat 45. The lever 44 can be connected to the torque port 7 via the connector 8 and can be adjusted and engaged by means of several equidistant torque ports 7.

[0042] This transmission structure 4, through its detachable splicing, torque port 7 fitting, and threaded adaptation design, achieves synchronous adaptation with the splicing length of the slide rail body 11. Furthermore, through its detachable connection with the guide structure 2 and the moving structure 3, it is compatible with three modes: screw drive, belt drive, and magnetic drive. Its spliced ​​screw lever 44 design solves the pain point of traditional screw drives being unable to adapt to variable length scenarios. Simultaneously, with the support of bearings and the torque block fitting structure, it ensures transmission stability and positioning accuracy under heavy-load conditions, providing core support for the module's high precision and multi-scenario applications.

[0043] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0044] The sliding structure 1 of the equipment serves as a guide carrier. The slide rail body 11 is inserted into the interface 17 of the side wall of the two slide rail bodies 11 respectively through the first adapter 14 and fixed by bolts to achieve docking. Then, it is supported by the guide frame 20 in the guide structure 2. The guide frame 20 is connected by inserting into the interface 17 of the slide rail body 11 through the second adapter 23.

[0045] like Figure 1 As shown, when the equipment is driven by magnetic transmission, after the slide rail body 11 is connected according to actual needs, multiple magnet bodies 13 are embedded in the magnetic groove 15. Since the magnet can penetrate the magnetic groove 15, the magnetic poles on the upper and lower sides are opposite. It can be flipped and corrected according to actual laying needs. In particular, the magnets are alternately set. The magnet body 13 can also be disassembled and flipped in the direction by the first bolt 12. The movable seat 31 in the movable structure 3 is sleeved on the slide rail body 11 through the sleeve 36, and the two ends of the sleeve 36 of the movable seat 31 are embedded in the guide groove 16, thereby ensuring that it can move in a straight line along the guide groove 16.

[0046] Then, the magnetic moving body 33 of the existing equipment is inserted into the mounting cavity 38 of the moving base 31 and tightened by the second bolt 32. The magnetic control structure on the lower wall of the magnetic moving body 33 can exert force relative to the magnet body 13 through the force receiving port 37, thereby using the magnetic force of the magnetic moving body 33 and the magnetic force of the magnet body 13 to push it to move in a straight line.

[0047] like Figure 2 As shown, when the equipment is driven by belt drive: the magnetic moving body 33 is removed from the mounting cavity 38 of the moving seat 31, and the conveyor belt 26 in the guide structure 2 is passed through the first guide port 5 and the second guide port 6. The conveyor belt 26 can be respectively fitted onto the guide rollers 22 between the roller frames 21 and the guide rollers 22 located in the guide frame 20. At this time, the conveyor belt 26 is fitted onto the outside of the slide rail body 11. At the same time, the conveyor belt 26 is passed through the first guide port 5 and enters the mounting cavity 38 of the moving seat 31. By screwing the pressing screw 34 and putting the pressure cap 35 on the pressing screw 34, the pressing screw 34 drives the cap to descend and press the conveyor belt 26, so that the conveyor belt 26 is connected to the moving seat 31.

[0048] Meanwhile, the first motor 27 is set on the upper wall of the other end of one of the guide frames 20. Then, with the help of the first motor 27 driving the pulley 28 and the roller shaft of one of the guide rollers 22, the pulleys 28 are linked together through the transmission belt 29. This enables the first motor 27 to drive one of the first guide rollers 22 to rotate and apply force, thereby driving the conveyor belt 26 to rotate, which in turn drives the moving seat 31 to move linearly along the slide rail body 11, ultimately achieving belt linear motion.

[0049] like Figure 3As shown, when the equipment is driven by a lead screw: after the slide rail body 11 is connected and supported by the guide frame 20, the moving seat 31 is also sleeved on the slide rail body 11. Then, the bearing platform 41 in the transmission structure 4 is inserted into the mounting groove 9 of the guide frame 20 and carries the second motor 42, causing the torque block at the drive end of the second motor 42 to pass through the middle of the second bearing 25. Then, a lead lever 44 of the corresponding length is laid according to the length of the slide rail body 11. Since one end of the lead lever 44 is provided with a connector 8 and the other end is provided with a matching torque port 7, the lead lever 44 can be connected to the torque port 7 at the other end by means of the connector 8. At the same time, one end of the lead lever 44 is connected to the sleeve 43 located in the middle of the first bearing 24 by means of the connector 8, and the lead lever 44 with the torque port 7 at the end is quickly connected to the torque block at the drive end of the second motor 42 to achieve a matching adjustment length.

[0050] Then, the drive seat 45 is bolted to the bottom of the movable seat 31, and the spiral hole in the middle of the drive seat 45 is screwed onto the lead lever 44. When the lead lever 44 is driven by the second motor 42 to rotate between the first bearing 24 and the second bearing 25, the drive seat 45 is forced and moves linearly in the guide groove 16 with the help of the movable seat 31, thus realizing linear drive of the lead screw.

[0051] Since guide grooves 16 are provided at both the upper and lower ends of the front and rear side walls of the slide rail body 11, the movable seats 31 can be symmetrically arranged on the upper and lower sides of the slide rail body 11, thereby realizing the movement of the double movable seats 31. If magnetic control is used for the double movable seats 31, staggered or synchronous movement can be realized. If belt movement is used, staggered movement can be realized.

[0052] In summary, the linear motor module of this invention offers flexible and adjustable splicing, adapting to various length requirements. It is compatible with three motion modes: magnetic drive, belt drive, and screw drive, significantly improving practicality, optimizing space utilization, supporting double-sided staggered motion, and featuring a detachable and easy-to-maintain structure that reduces operating costs. It also boasts strong compatibility, excellent expandability, high motion stability, and a long service life.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
