[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0053] A linear motor module generally has a magnetic track and a corresponding mover. When the magnetic track and the mover interact to drive the mover to move linearly, the slide of the linear motor module can move linearly relative to the base. Therefore, when driving the load device installed on the linear motor to move, if the weight of the load device is large, the thrust of a single magnetic track on the mover may not be able to drive the load device to move. Moreover, even if the load device can be driven to move, the movement of the load device cannot be stopped in time due to the small thrust, which will make the operation accuracy and stability of the linear motor poor, affecting the operation of the installed load device.

[0054] To this end, an embodiment of the present application provides a linear motor module and a workbench, which can ensure sufficient thrust to drive the load structure to move, thereby ensuring the accuracy and stability of the operation of the load structure.

[0055] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0056] like Figure 1 and Figure 2 As shown, a linear motor module 100 provided in an embodiment of the present application includes a base 10 , a slide 20 , a plurality of magnetic rails 30 and a plurality of movers 40 .

[0057] The slide 20 is slidably connected to the base 10. A plurality of magnetic tracks 30 are all arranged on the side of the base 10 facing the slide 20, and the plurality of magnetic tracks 30 are arranged at intervals along the first direction a. A plurality of movers 40 are all arranged on the side of the slide 20 facing the base 10, and the plurality of movers 40 are arranged at intervals along the first direction a. The plurality of movers 40 correspond to the plurality of magnetic tracks 30 one by one, and each mover 40 is arranged opposite to a magnetic track 30. The first direction a is perpendicular to the sliding direction of the slide 20 relative to the base 10.

[0058] It should be noted that in the present application, the term "multiple" means two or more, that is, the number of magnetic tracks 30 described in the present application is at least two, and the number of movers 40 is at least two.

[0059] It should be noted that, in each magnetic track 30 and the corresponding mover 40, after the control end energizes the mover 40, the mover 40 will generate a traveling magnetic field and interact with the corresponding magnetic track 30, and the magnetic track 30 will then provide a linear thrust to the mover 40. Since the magnetic track 30 is provided on the base 10 and the mover 40 is provided on the slide 20, the slide 20 can slide relative to the base 10 through the thrust. The thrusts of multiple magnetic tracks 30 to multiple movers 40 can be superimposed on each other, thereby increasing the thrust to the slide 20.

[0060] In the linear motor module 100 of the embodiment of the present application, each magnetic rail 30 will interact with the corresponding mover 40 to provide a driving force in a linear direction. The driving forces of multiple magnetic rails 30 to multiple movers 40 will be superimposed, thereby providing a larger thrust to the slide 20 to drive the slide 20 to slide relative to the base 10. In this way, the application range of the linear motor module 100 can be increased. For example, it can be used in operating conditions with heavy loads, high acceleration or certain impacts, and the accuracy and stability of the operation of the linear motor module 100 can be guaranteed. In addition, the linear motor module 100 has a shorter settling time in place. When the load structure is driven by the workbench of the linear motor module 100, sufficient thrust can be ensured to drive the load structure to move, thereby ensuring the accuracy and stability of the operation of the load structure.

[0061] In addition, when manufacturing the linear motor module 100, the multiple magnetic rails 30 and the multiple movers 40 are all of uniform specifications. Compared with the method of increasing the size of the mover 40 to provide a large thrust to the slide 20, the linear motor module 100 of the present application does not require additional production of different types of movers 40, and can be manufactured based on the existing movers 40, which can greatly simplify costs.

[0062] like Figure 1 and Figure 2As shown, in the embodiment of the present application, multiple movers 40 are connected in parallel. When the control end supplies power to the movers 40, current flows through the multiple movers 40 at the same time, which can ensure that the multiple magnetic rails 30 can act on the multiple movers 40 at the same time, thereby achieving the simultaneous pushing of the multiple movers 40, so that the slide 20 can slide stably and accurately. Of course, in other embodiments, the multiple movers 40 may not be connected, as long as it can be ensured that the multiple movers 40 are driven at the same time when the slider 513 is pushed to move.

[0063] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, a plurality of sliding structures 50 are provided on the side of the slide 20 facing the base 10, and the plurality of sliding structures 50 are all slidably connected to the base 10, and a mover 40 is provided between every two sliding structures 50. It should be noted that both sides of each set of magnetic rails 30 and movers 40 are provided with sliding structures 50, and the plurality of sliding structures 50 can stably carry the slide 20, and when the slide 20 slides relative to the base 10, the overall stable sliding of the slide 20 can be ensured.

[0064] like Figures 1 to 3 As shown, in the embodiment of the present application, the base 10 is provided with a plurality of sliding grooves 10a, and the plurality of sliding grooves 10a correspond to the plurality of sliding structures 50 one by one, and each sliding structure 50 is placed in a sliding groove 10a. The sliding structure 50 is placed in the sliding groove 10a, so that the height of the combination of the slide 20 and the base 10 can be reduced, the center of gravity can be lowered, and the slide 20 can further slide stably when moving under heavy load, high acceleration or operating conditions with certain impact.

[0065] like Figures 1 to 3 As shown, in the embodiment of the present application, the side walls of the sliding groove 10a along the first direction a are provided with slide rails 11, and the sliding structure 50 is provided with sliding members 51 on both sides of the first direction a, respectively. The sliding members 51 on both sides of the sliding structure 50 are slidably arranged on the slide rails 11 on both sides of the sliding groove 10a. The two sides of the sliding groove 10a are clamped on the two sides of the corresponding sliding structure 50, and the slide rails 11 on each side are provided for the sliding members 51 on the corresponding side to slide, so that each sliding structure 50 can slide stably in the corresponding sliding groove 10a. In addition, each sliding structure 50 distributes the bearing force between the sliding members 51 and the slide rails 11 on both sides, which can further stabilize the bearing slide 20, improve the rigidity of the linear motor module 100, and ensure the stable guided sliding of the slide 20 as a whole. In addition, compared with the structure of clamping the base 10 by the sliding member 51, the present embodiment integrates every two sliding members 51 on a sliding structure 50, which can reduce the number of components, so that the linear motor module 100 has a higher degree of integration and stronger rigidity.

[0066] Exemplarily, the sliding members 51 on both sides of each sliding structure 50 and the sliding rails 11 on both sides of the corresponding sliding groove 10 a are arranged on the same horizontal line to ensure stable sliding of the sliding structure 50 in each sliding groove 10 a.

[0067] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the sliding member 51 includes a returner 511 and a plurality of rolling bodies (not shown in the figure), the returner 511 is provided with a return channel, the return channel and the corresponding slide rail 11 are enclosed to form a closed loop, and the plurality of rolling bodies are arranged in the closed loop. During the rolling of the rolling body in the closed loop, the sliding member 51 can slide relative to the slide rail 11, so as to realize the sliding of the slide table 20 relative to the base 10. Through the provided returner 511 and the plurality of rolling bodies, the friction resistance of the sliding member 51 when sliding can be reduced, which is beneficial to the linear motion of the slide table 20.

[0068] In the embodiment of the present application, the rolling body plays the role of supporting the slide 20 and bearing the load. When the rolling body rolls in the slide rail 11, it is in two-point contact with the slide rail 11, and the two-point contact position is at an angle of ±45° with the horizontal plane. Therefore, in each set of sliding structures 50 and sliding grooves 10a, there are four points of load bearing. Moreover, as the number of sliding structures 50 and sliding grooves 10a increases, the positions of the load bearing also increase. Therefore, it is possible to ensure stable support for the entire slide 20 and the load thereon, and provide stable guidance for the slide 20. Exemplarily, the number of sliding structures 50 and sliding grooves 10a is three, and in this example, there are twelve points of load bearing.

[0069] Exemplarily, the reflux channel includes a closed channel located inside the sliding structure 50 and a semi-closed channel located on the side wall of the sliding structure 50, wherein the semi-closed channel cooperates with the sliding groove 10a, so that the rolling body can circulate and roll in the closed channel and the passage in which the semi-closed channel and the sliding rail 11 cooperate.

[0070] For example, the sliding member 51 on each side of the sliding structure 50 is provided with a plurality of returners 511, and the plurality of returners 511 are arranged at intervals along the sliding direction of the slide 20, and each closed loop formed by the returner 511 and the slide rail 11 is provided with a plurality of rolling bodies to ensure the stable sliding of the slide 20 as a whole relative to the base 10. Figure 4 As shown, further, the sliding member 51 further includes a slider 513 disposed between adjacent returners 511, and the slider 513 is provided with a protrusion adapted to the slide rail 11, so that the slider 513 can also realize the guided sliding of the sliding member 51 and support the slide 20. In this way, combined with the support of the slide 20 by the ball bearing, the stable support of the entire slide 20 and the load thereon can be ensured, and the slide 20 can be provided with a stable guide.

[0071] Exemplarily, the rolling element includes a steel rolling element, and the rolling element with a steel structure can ensure that it has sufficient structural strength to achieve stable guide rolling and support the slide 20 and the load thereon.

[0072] like Figure 2 and Figure 3 As shown, in the embodiment of the present application, the side wall of the sliding groove 10a is provided with a groove, and the slide rail 11 is embedded in the groove. After the slide rail 11 is embedded in the groove, the slideway of the slide rail 11 is finely ground to ensure the overall guiding accuracy of the base 10 to the slide table 20. Of course, in other embodiments, the slide rail 11 can also be integrally formed on the base 10.

[0073] Exemplarily, the slide rail 11 is a steel rail to ensure sufficient structural strength to ensure stable sliding of the sliding member 51 and stable support of the slide table 20 .

[0074] like Figure 1 and Figure 3 As shown, in the embodiment of the present application, the side walls of the slide 20 on both sides along the first direction a are respectively provided with oil injection holes 20b, and each oil injection hole 20b is connected to the sliding structure 50 close to the oil injection hole 20b. In this way, lubricating grease can be injected into the sliding structure 50 at the edges of both sides of the slide 20 through the oil injection hole 20b, ensuring that the sliding structure 50 at the edges of both sides can slide stably relative to the base 10. Specifically, the oil injection hole 20b is connected to the return flow device 511 of the sliding structure 50 at the edges of both sides, so that lubricating grease can be injected into the return flow device 511 through the oil injection hole 20b to lubricate the rolling of the rolling body and ensure the smooth rolling of the rolling body.

[0075] like Figure 1 and Figure 3 As shown, in the embodiment of the present application, the slide 20 is further provided with an oil injection pipe 21 penetrating the slide 20, and the oil injection pipe 21 is connected to the sliding structure 50 between the sliding structures 50 at the two edges. In this way, lubricating grease can be injected into the middle sliding structure 50 through the oil injection pipe 21 to ensure that the middle sliding structure 50 can slide stably relative to the base 10. Specifically, the oil injection pipe 21 is connected to the return flow device 511 of the middle sliding structure 50, so that lubricating grease can be injected into the return flow device 511 through the oil injection hole 20b to lubricate the rolling of the rolling body and ensure the smooth rolling of the rolling body.

[0076] Exemplarily, there are three sliding structures 50 in total, and the middle sliding structure 50 is connected to the outside through two oil filling pipes 21, so that lubricating grease can be injected into the returners 511 on both sides of the middle sliding structure 50 through the two oil filling pipes 21 respectively.

[0077] like Figure 2 and Figure 3As shown, in the embodiment of the present application, the base 10 is provided with a first surface 101 facing the slide 20, and the first surface 101 is provided with a plurality of sliding grooves 10a and a plurality of first mounting grooves, and the plurality of first mounting grooves correspond to the plurality of magnetic rails 30 one by one, and each magnetic rail 30 is installed in a first mounting groove, and the surfaces of the plurality of magnetic rails 30 facing the slide 20 are all flush with the first surface 101. It can be understood that since the sliding structure 50 is placed in the sliding groove 10a and is slidably connected to the base 10, compared with the sliding connection with the structure protruding from the base 10, the deformation of the sliding groove 10a can be avoided, thereby ensuring the accuracy and stability of the operation of the slide 20. In addition, since the surface of the magnetic rail 30 is flush with the first surface 101, it can be avoided that foreign matter accumulates on the surface of the magnetic rail 30 and jams the operation of the linear motor module 100. In addition, the gap between the base 10 and the slide 20 can be reduced. On the one hand, this makes the linear motor module 100 more compact. On the other hand, it also reduces the noise generated by the linear motor module 100 during operation, ensuring the normal operation of the linear motor and making the use environment quieter and more comfortable.

[0078] In combination with the above, the sliding structure 50 is slidably connected to the slide rail 11 of the sliding groove 10a through the sliding parts 51 on both sides. In this embodiment, the height of the slide rail 11 can be lowered to be close to the bottom surface. The base 10 is no longer a U-shaped cavity structure, but a flat structure. The flattened design reduces the height of the slide rail 11. The slide rail 11 is not easy to deform during integrated grinding, and the precision is more stable and the rigidity is stronger.

[0079] like Figure 2 and Figure 3 As shown, in the embodiment of the present application, each magnetic rail 30 is adapted and fixed to a first mounting groove. It can be understood that the peripheral side of the magnetic rail 30 will abut against the side wall of the first mounting groove. Through the support of the magnetic rail 30 on the peripheral side of the first mounting groove, the slide rail 11 can be further prevented from deformation, ensuring the stable sliding of the sliding member 51.

[0080] like Figure 2 and Figure 3 As shown, in the embodiment of the present application, the linear motor module 100 further includes a first connecting member, a first mounting hole communicating with the outside is provided at the bottom of the first mounting slot, the first connecting member is passed through the first mounting hole, and is fixedly connected to the magnetic rail 30. The first connecting member fixes the magnetic rail 30 upward from the bottom of the base 10, cancels the mounting holes on both sides, and the overall width of the base 10 is narrower, which is conducive to the compression of the overall width dimension of the linear motor module 100.

[0081] Exemplarily, in each magnetic rail 30 and the corresponding first mounting groove, a plurality of first connecting members and a plurality of first mounting holes are provided, and the plurality of first connecting members and the plurality of first mounting holes correspond one to one. Each first connecting member is passed through a first mounting hole to be fixedly connected to the magnetic rail 30, thereby ensuring the overall stable installation of the magnetic rail 30.

[0082] Exemplarily, the first connecting member includes a screw, and the first connecting member and the magnetic rail 30 are threadedly connected and fixed.

[0083] like Figure 2 and Figure 4 As shown, in the embodiment of the present application, the slide 20 is provided with a second surface 201 facing the base 10, and a plurality of sliding structures 50 are all protruding from the second surface 201. The second surface 201 is provided with a plurality of second mounting grooves, and the plurality of second mounting grooves correspond to the plurality of movers 40 one by one. Each mover 40 is installed in a second mounting groove, and the surfaces of the plurality of movers 40 facing the base 10 are all flush with the second surface 201. It should be noted that the sliding structure 50 can be integrally provided on the slide 20. Of course, the sliding structure 50 can also be connected to the slide 20 by installation and fixing, and the portion of the slide 20 protruding from the second surface 201 is placed in the sliding groove 10a to achieve sliding connection with the base 10. In this embodiment, the mover 40 is provided in the second mounting groove, so that the height of the slide 20 and the mover 40 combination can be reduced, so that the overall height of the linear motor module 100 is reduced, the problem of top-heavy is improved, the center of gravity is more stable, and the linear motor module 100 has higher operating accuracy and stability, and stronger rigidity. In addition, the surface of the slide 20 is flush with the second surface 201, which, on the one hand, makes the linear motor module 100 more compact, and on the other hand, reduces the noise generated by the linear motor module 100 during operation, ensuring the normal operation of the linear motor and making the use environment quieter and more comfortable.

[0084] By setting the sliding mounting groove and the first mounting groove in combination with the above-mentioned first surface 101, the structure inside the entire linear motor module 100 can be compact and the gap can be reduced, so that the linear motor module 100 can be further flattened, so that the linear motor module 100 can operate with higher accuracy and stability and stronger rigidity.

[0085] like Figure 2 and Figure 4 As shown, in the embodiment of the present application, each mover 40 is adapted and fixed to a second mounting groove. In this way, the mover 40 can be stably mounted in the second mounting groove, and the mover 40 can be made large enough to ensure that the magnetic rail 30 can provide a sufficiently large thrust to the mover 40, and then provide a sufficiently large thrust to the slide 20 as a whole.

[0086] like Figure 2 and Figure 4 As shown, in the embodiment of the present application, the mover 40 and the slide 20 are integrally molded by glue pouring. In this way, the step of assembling the mover 40 with the slide 20 after producing the mover 40 by the glue pouring mold is omitted, and the production process is simpler. In addition, the mover 40 and the slide 20 are integrally packaged and molded, and the connection is tighter, and the structural strength and connection rigidity of the slide 20 are also improved.

[0087] Exemplarily, first glue pouring grooves 20c are provided on the side walls of the second mounting groove on both sides along the first direction a. When the mover 40 and the slide 20 are integrally molded by glue pouring, glue can be filled into the first glue pouring grooves 20c to fasten the mover 40 and the slide 20.

[0088] Exemplarily, a plurality of second glue pouring grooves 40a are also provided on one side of the bottom wall of the mover 40 facing the second mounting groove. When the mover 40 and the slide 20 are integrally glue-molded, glue can be filled into the second glue pouring grooves 40a to fasten the mover 40 and the slide 20.

[0089] like Figure 2 and Figure 4 As shown, in the embodiment of the present application, the slide 20 is provided with a slide groove 20a opening toward the base 10, a portion of the base 10 is placed in the slide groove 20a, and the second surface 201 is formed at the bottom of the slide groove 20a. It can be understood that the slide 20 as a whole is wrapped around a portion of the base 10 along the first direction a, and in this embodiment, is wrapped around the top of the base 10. In this way, the overall height of the linear motor module 100 can be further reduced, the center of gravity is more stable, and the linear motor module 100 has higher operating accuracy and stability, and stronger rigidity.

[0090] like Figure 3 and Figure 4 As shown, in the embodiment of the present application, a linear encoder 61 is provided on the side of the slide 20 facing the base 10, the base 10 is provided with a scale 62 matched with the linear encoder 61, and the base 10 is provided with a wire groove 10b extending along the sliding direction of the slide 20, and the linear encoder 61 and the scale 62 are both placed in the wire groove 10b. The linear encoder 61 and the scale 62 can provide position feedback for the linear motion of the slide 20. The position information can be fed back to the control end, so that the control end can accurately know the current position of the slide 20, so that it can accurately control the position of the slide 20 by controlling multiple movers 40, thereby achieving precision operation. In this embodiment, the linear encoder 61 and the scale 62 are both placed in the wire groove 10b, which can effectively protect the linear encoder 61 and the scale 62, thereby ensuring accurate position feedback.

[0091] Exemplarily, the wire slot 10b is located between two of the magnetic rails 30. Specifically, the wire is located between the two first installation slots and between one of the installation slots and the sliding slot 10a, so as to effectively prevent external dust from entering the wire slot 10b.

[0092] like Figure 1 and Figure 2As shown, in the embodiment of the present application, the side wall of the slide 20 is provided with a photoelectric sensing sheet 71, and the side wall of the base 10 is provided with a photoelectric sensor 72 that cooperates with the photoelectric sensing sheet 71. The photoelectric sensing sheet 71 corresponds to the photoelectric sensor 72 in position so as to provide position feedback. When the slide 20 slides relative to the base 10, the photoelectric sensing sheet 71 passes through the sensing groove of the photoelectric sensor 72, and the photoelectric sensor 72 then senses the position of the sliding component and feeds it back to the control end, and the control end can control the sliding component according to the position information of the sliding component.

[0093] like Figure 3 As shown, in the embodiment of the present application, the base 10 is provided with a buffer seat 12 at both ends of the sliding direction of the slide 20, and the slide 20 is provided with a buffer rubber 22 at both ends of the sliding direction of the slide 20, and the buffer rubber 22 and the buffer seat 12 are arranged relative to each other. The buffer seat 12 can limit the sliding of the slide 20 to ensure the safe and stable operation of the linear motor module 100. In addition, when the slide 20 contacts the buffer seat 12, the buffer rubber 22 will first contact the buffer seat 12, and the elastic deformation of the buffer rubber 22 can buffer the movement of the slide 20 to prevent the slide 20 from bumping.

[0094] like Figure 1 and Figure 3 As shown, in the embodiment of the present application, two groups of accordion covers 80 are further provided, and the two ends of the slide 20 along the sliding direction of the slide 20 are connected to the two ends of the base 10 through the two groups of accordion covers 80 respectively. It can be understood that the accordion cover 80 is provided on the upper side of the base 10. It should be known that the accordion cover 80 can be extended and retracted along the sliding direction of the slide 20, and the interior of the linear motor module 100 can be effectively protected by the two groups of accordion covers 80. When the slide 20 performs a linear motion relative to the base 10, the accordion cover 80 at one end is extended and the accordion cover 80 at the other end is shortened. In this way, during the movement of the slide 20, the interior of the linear guide module is guaranteed to be closed to achieve internal sealing protection.

[0095] like Figure 2 and Figure 3 As shown, in the embodiment of the present application, two magnetic rails 30 and two movers 40 are provided in the linear motor module 100, and three sliding structures 50 are provided to ensure the operating accuracy and stability of the linear motor module 100 while providing a large thrust to the slide 20.

[0096] like Figure 2 and Figure 5 As shown, the present application also provides a workbench, including two sets of linear motor modules 100 .

[0097] The base 10 of one set of linear motor modules 100 is installed on the slide 20 of another set of linear motors, and the slide 20 of one set of linear motor modules 100 is used to connect the load structure. The sliding directions of the slides 20 of the two sets of linear motor modules 100 have an angle.

[0098] In the workbench of the embodiment of the present application, in each linear motor module 100, the thrusts of multiple magnetic rails 30 to multiple movers 40 are superimposed, thereby providing a larger thrust to the slide 20 to drive the slide 20 to slide relative to the base 10. In this way, each linear motor module 100 can provide a larger thrust, and ensure the operating accuracy and stability of the linear motor module 100. When the workbench is used to drive the load structure, sufficient thrust can be ensured to drive the load to move, thereby ensuring the accuracy and stability of the operation of the load structure.

[0099] For example, the sliding directions of the slides 20 of the two sets of linear motor modules 100 are perpendicular. Through the movement in two perpendicular directions, the worktable can drive the load structure to move freely in the entire plane, so that the load structure can achieve corresponding operations with accurate control accuracy.

[0100] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the application concept of the present application, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present application.
