Description

Technical Field

[0001] The present disclosure relates to the field of motor drive, and more specifically to a through-type linear module. Background Art

[0002] The linear module is an automation upgrade unit following the linear guide and ball screw linear transmission mechanism. It can realize the linear and curved motion of the load through the combination of various units, making the automation of light loads more flexible and the positioning more accurate. Since its development, the linear module has been widely used in various equipment.

[0003] Some common linear modules in the current market generally use wide motors to drive the modules. Usually, a rotary motor plus a coupling is used to transfer the screw, and the screw thread and the matching nut are used to convert the rotary motion into linear motion. The wide motor is relatively large, and the matching module part will also become larger. In some cases where the space is very small and the load object is relatively small, these modules are too bulky and complicated. At the same time, almost all existing linear modules are made of external drive motor structure with supporting linear guides. Such a structure is not conducive to saving space. Not only does the tail of the module need to reserve space for the installation of the motor, but the inside of the module also needs to be equipped with a slider connecting the linear guide and the nut. The size of the slider and the motor both occupy a large space.

[0004] Therefore, a new linear module is needed that can overcome the shortcomings of the prior art and bring other advantages. Summary of the invention

[0092] Below, the through-type linear module according to the embodiment of the present disclosure is described in detail with reference to the accompanying drawings. In order to make the purpose, technical solution and advantages of the present utility disclosure clearer, the technical solution in the embodiment of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present disclosure.

[0097] like Figure 1-3 As shown, the present disclosure provides a through-type linear module 1. According to one embodiment, the through-type linear module 1 of the present disclosure may include a support assembly 30, a motor assembly 10 and a screw 20. The support assembly 30 is fixedly arranged to support other components of the linear module 10. Figure 1-4 As shown, in this embodiment, the motor assembly 10 includes a motor body 100, and the motor body 100 includes a rotatable rotor assembly 110. A longitudinal through hole 120 is provided at the center of the rotor assembly 110, and an internal thread 130 is provided on the hole wall of the longitudinal through hole 120. More specifically, the internal thread 130 can be provided on the driving section of the longitudinal through hole 120, and the driving section is a part of the longitudinal through hole 120, for example, located in the longitudinal middle part of the longitudinal through hole 120. In a specific embodiment, as Figure 3 and 4As shown, the rotor assembly 110 may include an injection molded portion 140, a longitudinal through hole 120 is arranged at the center of the injection molded portion 140, and therefore the internal thread 130 is arranged on the injection molded portion 140. In a specific embodiment, the motor body 100 is a stepper motor. More specifically, the motor body 100 is a stepper motor with a width of 14 mm. In a specific embodiment, the electronic body 100 also includes a stator assembly 150, and the rotor assembly 110 is radially located inside the stator assembly 150. The screw rod 20 is arranged to be fixed, more specifically fixed relative to the support assembly 30, and the screw rod 20 is arranged to pass through the longitudinal through hole 120 of the rotor assembly 110, and is provided with an external thread 230 that cooperates with the internal thread 130 of the hole wall of the longitudinal through hole 120. Thus, when the rotor assembly 110 rotates, the internal thread 130 on the hole wall of the longitudinal through hole 120 meshes with the external thread 230 on the screw rod 20, so that the rotational motion of the rotor assembly 110 can be converted into the linear translational motion of the motor assembly 10, more specifically, the linear translational motion along the screw rod 20 relative to the support assembly 30. It should be noted that the longitudinal direction is the main extension direction of the screw rod 20.

[0098] Thus, the through-type linear module 1 proposed in the present disclosure converts the rotational motion of the rotor assembly 110 into the translational motion of the motor assembly 10 by setting the rotor assembly 110 of the motor assembly 10 as a through-type, and setting the screw rod 20 to pass through the longitudinal through hole 120 of the rotor assembly 110, and at the same time converts the rotational motion of the rotor assembly 110 into the translational motion of the motor assembly 10 through the engagement between the external thread 230 of the screw rod 20 and the internal thread 130 on the hole wall of the longitudinal through hole 120, thereby eliminating the use of the coupling and the nut assembly, allowing the overall size of the linear module to be reduced and its cost to be reduced. In addition, the through-type linear module 1 disclosed in the present disclosure does not need to reserve the installation space of the motor at the tail, which is further conducive to achieving a compact overall structure.

[0099] In some embodiments, Figure 4 As shown, the stator assembly 150 of the motor body 100 can be integrally injection molded. Specifically, the integrally injection molded stator assembly 150 mainly includes a stator core 151, a skeleton and a bracket at both ends of the stator core, which are combined into one by injection molding. The integral injection molding can ensure that these components are reliably connected. At the same time, the integrally injection molded stator assembly 150 has no front and rear cover structures, which is very convenient for installation. The rotor assembly 110, more specifically the injection molded portion 140 of the rotor assembly 110, is supported in the stator assembly 150 at both ends via a first bearing 111 and a second bearing 112, respectively. In addition, the two ends of the rotor assembly 110 are axially retained via a retaining ring 113 and a pre-tightening nut 114, respectively.

[0100] According to some embodiments, Figure 1-3As shown in Figures 5 and 6, the through-type linear module 1 further includes a slide rail assembly 40, which includes a guide rail 410, and the guide rail 410 is configured to guide the translational movement of the motor assembly 10. In a specific embodiment, as shown in the figure, the slide rail assembly 40 may also include at least one slider 420a, 420b, and the at least one slider 420a, 420b is configured to be connected to the motor assembly 10 and is configured to cooperate with the guide rail 410 so as to be able to perform translational movement along the guide rail 410 with the motor assembly 10. That is, in such an embodiment, the guide rail 410 guides the translational movement of the motor assembly 10 via the at least one slider 420a, 420b. More specifically, when the motor assembly 10 translates along the lead screw 20 due to the engagement of the internal thread 130 of the hole wall of the longitudinal through hole 120 of the rotor assembly 110 with the external thread 230 of the lead screw 20, the motor assembly 10 drives the at least one slider 420a, 420b to also translate, and the at least one slider 420a, 420b cooperates with the guide rail 410 at the same time, so that the translational movement is more stable due to the guidance of the guide rail 410. More specifically, the guide rail 410 is arranged below the sliders 420a, 420b. In a more specific embodiment, as shown in the figure, the support assembly 30 of the through-type linear module 1 may include a guide rail mounting seat 350 configured to support and fix the guide rail 410. More specifically, the guide rail mounting seat 350 is arranged below the guide rail 410.

[0101] In some embodiments, Figure 1-3 As shown in Figures 1 and 5, the motor assembly 10 also includes a motor mounting seat 160 configured to hold and support the motor body 100, and the at least one slider 420a, 420b is connected to the motor mounting seat 160 so as to be able to perform translational movement with the motor assembly 10. In a specific embodiment, the motor mounting seat 160 has an L-shape, including a flat plate 170 extending in the longitudinal direction and a vertical plate 180 extending perpendicular to the longitudinal direction, and the flat plate 170 and the vertical plate 180 are connected to each other at corresponding ends. More specifically, the at least one slider 420a, 420b can be connected to the flat plate 170 below the flat plate 170, for example, connected to the flat plate 170 via screws. Thereby, the connection between the motor assembly 10 and the sliders 420a, 420b can be achieved via the motor mounting seat 160.

[0102] In some embodiments, Figure 2As shown, each slider 420a, 420b is provided with a guide slot 421 that cooperates with the guide rail 410. More specifically, the guide slot 421 is provided in the lower side of the sliders 420a, 420b, and as a whole has a U-shaped shape opened at the lower side in a cross section perpendicular to the longitudinal direction, and ribs 422 are provided on the first inner side wall and the second inner side wall of the guide slot 421 corresponding to the two legs of the U-shaped shape, and grooves 412 are provided on the first outer side wall and the second outer side wall of the guide rail 410, and the sliders 420a, 420b straddle the guide rail 410 via the guide slot 421, and the ribs 422 are received in the grooves 412, so that the guide rail 410 can guide the sliders 420a, 420b stably.

[0103] In some embodiments, Figure 1-3 As shown in Figures 5 and 6, the slide rail assembly 40 may include a first slider 420a and a second slider 420b that are separately arranged. More specifically, the first slider 420a and the second slider 420b are arranged successively along the longitudinal direction. For example, the structures of the first slider 420a and the second slider 420b are exactly the same, but they may also be different. The provision of two sliders effectively solves the problem of accurate weight finding when a single slider is used. More specifically, conventional modules are usually equipped with a single slider. In this case, it is necessary to determine the overall center of gravity of the load and the slider to determine the position of the slider, and if the load changes, the center of gravity position needs to be adjusted, which is not suitable for large-scale production. Placing two sliders can effectively solve this problem. The double slider is less affected in the case of center of gravity deflection and will not affect the entire operation process. In addition, in the present disclosure, since the motor assembly 10 is directly connected to the slide rail assembly 40 through the motor mounting seat 160, the overall weight supported by the slide rail assembly 40 will also increase. Therefore, the use of a double slider structure can support a larger load and effectively avoid deflection and assembly inequality.

[0104] In some embodiments, Figure 2-3 As shown, a first positioning recess 181 may be provided in the vertical plate 180, and a first positioning protrusion 101 may be provided at the front end of the motor body 100 facing the vertical plate 180, and the first positioning protrusion 101 may be fitted in the first positioning recess 181; more specifically, the first positioning protrusion 101 is a cylindrical protrusion, which may be fitted in the first positioning recess 181 in a shape-fitting manner. In another specific embodiment not shown, a second positioning protrusion may be provided in the vertical plate 180, and a second positioning recess may be provided at the front end of the motor body 100, and the second positioning protrusion may be fitted in the second positioning recess; more specifically, the second positioning protrusion is a cylindrical protrusion, which may be fitted in the second positioning recess in a shape-fitting manner. In a specific embodiment, the vertical plate 180 of the motor mounting seat 160 is connected to the front end of the motor body 100 using screws (not shown). More specifically, as Figure 2As shown, the vertical plate 180 may be provided with screw receiving recesses 182 and screw through holes 183 at the four corners, and a corresponding threaded hole 102 may be provided at the front end of the motor body 100. The screws may pass through the screw through holes 183 at the corresponding receiving recesses 182 and be screwed into the threaded holes 102 in the front end of the motor body 100 to fix the motor body 100 relative to the motor mounting seat 160. Thus, the L-shaped motor mounting seat 160 can save space most effectively while facilitating the installation of the motor body 100 and the motor mounting seat 160. The vertical plate 180 is connected to the front end of the motor body 100, and the cooperation of the positioning protrusion and the positioning recess ensures the centering of the motor body 100, and allows the concentricity and straightness of the screw rod 20 and the motor assembly 10 to be ensured. In addition, as Figure 2 As shown, a through hole 184 for the screw rod 20 to pass through is provided in the vertical plate 180 of the motor mounting seat 160 .

[0105] like Figure 3 As shown, in some embodiments, a gap G is provided between the flat plate 170 of the motor mounting seat 160 and the lower side of the motor body 100. The existence of the gap G facilitates the installation of the motor body 100 on the motor mounting seat 160 on the one hand, because if there is no gap, the motor body 100 must be absolutely parallel to the flat plate 170 of the motor mounting seat 160 when installing the motor body 100, otherwise the screw rod 20 will bend; on the other hand, considering factors such as the tolerance of the motor body 100, the gap G can ensure the downward adjustability of the motor body 100. In a specific embodiment, the size of the gap G is greater than or equal to 0.03 mm and less than 1.5 mm. It should be noted that in this case, the first or second positioning protrusion mentioned above is loosely fitted in the first or second positioning recess.

[0106] Therefore, the width of the through-type linear module 1 of the present disclosure can be set to be consistent with the width of the motor body 100, and the height only needs to be the height of the motor assembly 10 plus the height of the slide rail assembly 40 and the guide rail mounting seat 350. In a specific embodiment, the overall width of the through-type linear module 1 of the present disclosure can be about 14 mm, and the overall height can be about 25 mm.

[0107] In some embodiments, Figure 1-3As shown in Figures 5 and 6, the support assembly 30 of the through-type linear module 1 may include a first support plate 310 and a second support plate 320 for supporting and holding the screw rod 20 and arranged opposite to each other. The screw rod 20 includes a first end 210 and a second end 220 opposite to each other. The first end 210 of the screw rod 20 is connected to the first support plate 310, and the second end 220 of the screw rod 20 is connected to the second support plate 320. In a specific embodiment, a first hole 311 is provided in the first support plate 310, and the first hole 311 is provided with an internal threaded hole section. The first end 210 of the screw rod 20 is correspondingly provided with an external threaded shaft end for matching with the internal threaded hole section, thereby achieving the fixing of the first end 210 of the screw rod 20 in the first support plate 310. More specifically, a second hole 321 is provided in the second support plate 320, and the second end 220 of the screw rod 20 is arranged to be inserted into the second hole 321; more specifically, the second end 220 of the screw rod 20 is in the form of an optical axis. Thus, the first end 210 of the screw rod 20 is connected to the first support plate 310 through a threaded connection, and the second end 220 in the form of an optical axis inserted into the second support plate 320 plays a role in supporting the screw rod 20 and ensuring the straightness and centering of the screw rod 20. In a more specific embodiment, the first hole 311 of the first support plate 310 can also be provided with a non-threaded hole section, and the first end 210 of the screw rod 20 can also be correspondingly provided with a non-threaded shaft section for matching with the non-threaded hole section, thereby further ensuring the centering and straightness of the screw rod 20, thereby further ensuring the verticality of the screw rod 20 and the first support plate 310 and the second support plate 320. More specifically, the first end 210 and the second end 220 of the screw rod 20 will not protrude outward from the corresponding first support plate 310 and the second support plate 320, thereby ensuring that the longitudinal length of the linear module will not be increased.

[0108] In a specific embodiment, the outer diameter of the second end 220 of the screw rod 20 is smaller than the inner diameter of the second hole 321 in the second support plate 320. In this way, the screw rod 200 can be guaranteed to have an adjustable space to prevent the risk of the overall structure being stuck. More specifically, a vibration-damping member (not shown), such as a vibration-damping pad or a silent sleeve, can also be provided around the second end 220 of the screw rod 20 in the second hole 310 of the second support plate 320 to prevent the screw rod 20 from directly hitting the first and second support plates of the metal material to generate a large vibration noise.

[0109] It can be understood that the first end 210 of the screw 20 of the through-type linear module 1 proposed in the present disclosure is fixed to the first support plate 310 by means of threads and possible adhesives, such as glue, and the second end 220 of the screw 20 is supported in the second support plate 320, and the screw 20 is fixed as a whole. At the same time, the motor body 100 is only fixed to the vertical plate 180 of the motor mounting seat 160 by screws, so when there is a problem with the motor body 100 or the life of the internal thread 130 inside the motor body 100 is reached, the motor body 100 can be replaced by only disassembling the second support plate 320 and the screws. After the replacement is completed, there is no need to level the entire module, reassemble, etc.
