Description

Technical Field

[0001] This invention relates to the field of mobile output device technology, and more specifically, to a displacement platform and a planar displacement device. Background Technology

[0002] In industrial automation production sites, a displacement platform is often used to output minute displacements in order to precisely adjust the position of the materials or workpieces it carries. Currently, most displacement platforms on the market use a lead screw drive mechanism, which uses a rotary motor to drive the lead screw to rotate, and works in conjunction with the lead screw nut and guide rails to achieve precise displacement output.

[0003] However, the aforementioned method of achieving precise displacement output using a lead screw drive mechanism typically involves arranging a rotary motor and the lead screw drive mechanism sequentially in the displacement direction. When horizontal displacement is required, this results in a large overall lateral dimension of the platform, occupying a significant amount of lateral space, thus making it unsuitable for scenarios with limited lateral space. Summary of the Invention

[0004] The first objective of this invention is to provide a displacement platform to solve the technical problem that existing displacement platforms for outputting horizontal displacement have a large lateral dimension.

[0005] The displacement platform provided by this invention includes a housing, a mounting base, a rotary motor, a gear, a rack, an output platform, and a guide structure. The mounting base is fixedly connected to the housing from the outside. The rotary motor is housed within the housing, and its output shaft extends from the housing and into the mounting base, extending longitudinally along the housing. The gear is fixedly fitted onto the output shaft, and the rack extends laterally along the housing and meshes with the gear. The output platform includes a longitudinal section and a transverse section. The mounting base and the longitudinal section are arranged laterally along the housing. The gear is disposed inside the mounting base, and the rack is disposed in the longitudinal section. The longitudinal, first, and second transverse sections of the housing are perpendicular to each other. The transverse section, the mounting base, and the housing are arranged sequentially along the longitudinal direction of the housing. The guide structure is disposed between the mounting base and the output platform to guide the output platform to move laterally along the housing.

[0006] Furthermore, the displacement platform also includes a displacement detection element, which is disposed between the mounting base and the output platform.

[0007] Furthermore, the displacement detection element is disposed between the transverse section and the mounting base, and the guide structure is disposed between the mounting base and the longitudinal section.

[0008] Furthermore, a detection space is provided on the part of the mounting base facing the transverse segment, and the displacement detection element is accommodated in the detection space.

[0009] Furthermore, the mounting base includes a bottom wall fixedly connected to the housing, and the bottom wall has a wiring channel that connects the detection space with the inner cavity of the housing.

[0010] Furthermore, the mounting base also includes a enclosure wall, which includes a first side wall, a second side wall, and a third side wall connected in a U-shape. The longitudinal segment is located between the first side wall and the third side wall along the first transverse direction of the housing. The first side wall and the third side wall are used to limit the sliding stroke of the output platform along the first transverse direction of the housing.

[0011] Furthermore, the displacement platform also includes a cover plate, which is fixedly connected to the mounting base. The cover plate has a limiting opening that is opposite to the transverse segment along the longitudinal direction of the housing. The limiting opening includes a first edge and a second edge that are opposite to each other along the first transverse direction of the housing, and a third edge and a fourth edge that are opposite to each other along the second transverse direction of the housing. A boss is provided on the side of the transverse segment facing the detection space. The boss is embedded in the limiting opening, and the displacement detection element is disposed between the boss and the mounting base.

[0012] Furthermore, the mounting base also includes a partition connecting the first sidewall and the third sidewall, and the first sidewall, the second sidewall, the third sidewall and the partition together form the detection space.

[0013] Furthermore, the circuit board of the displacement platform is disposed in the inner cavity of the housing, and the circuit board is arranged along the longitudinal direction of the housing; and / or, the displacement platform further includes a tension spring, one end of which is fixedly connected to the mounting base, and the other end of which is fixedly connected to the output platform, and the tension spring always has a tendency to drive the output platform to slide along the first lateral direction of the housing.

[0014] The beneficial effects of the displacement platform of this invention are:

[0015] When in use, the rotary motor operates, driving the gears to rotate. Through the meshing transmission of the gears and rack, the rack outputs a first lateral displacement along the housing, thus enabling the output platform, fixedly connected to the rack, to output this first lateral displacement along the housing. The material or workpiece can be carried by the output platform.

[0016] This displacement platform connects the housing and the mounting base along the longitudinal direction of the housing. The rotary motor is installed inside the housing cavity with its output shaft also along the longitudinal direction of the housing. The rack is arranged along the second transverse direction of the housing with the gear. Because the rack is located in the longitudinal section, the power transmission path during operation is: output shaft - gear - rack - longitudinal section, and the power transmission direction is: longitudinal direction of the housing - second transverse direction of the housing - longitudinal direction of the housing. On the one hand, the drive components that were originally collinear with the displacement direction of the output platform in the prior art are moved to a direction perpendicular to it, effectively reducing the overall transverse dimension of the displacement platform. On the other hand, embedding the output shaft of the rotary motor and the gear fixedly mounted on the output shaft into the mounting base also achieves a rational layout of components, making the structure of the displacement platform more compact.

[0017] The second objective of this invention is to provide a planar displacement device to solve the technical problem that the existing displacement platforms used for outputting horizontal positions have a large lateral dimension.

[0018] The planar displacement device provided by the present invention includes two displacement platforms as described above. In the two displacement platforms, the mounting base of one displacement platform is mounted on the output platform of the other displacement platform, and the output directions of the two displacement platforms are perpendicular to each other.

[0019] The beneficial effects of the planar displacement device of the present invention are:

[0020] By incorporating the aforementioned displacement platform into the planar displacement device, the planar displacement device acquires all the advantages of the aforementioned displacement platform, which will not be elaborated upon here.

[0021] In addition, by setting two displacement platforms in the planar displacement device and making the output directions of the two displacement platforms perpendicular to each other, the motion of the two displacement platforms can be superimposed, so that when the material or workpiece is carried on the output platform of one of the displacement platforms, the material or workpiece can obtain two-dimensional displacement output on the horizontal plane.

[0041] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0042] like Figures 1 to 3 As shown, this embodiment provides a displacement platform.

[0043] like Figure 4 and Figure 5 As shown, the displacement platform includes a housing 510, a mounting base 520, a rotary motor 110, a gear 210, a rack 220, an output platform 300, and a guide structure 700. The mounting base 520 is fixedly connected to the housing 510 outside the housing 510. The rotary motor 110 is housed within the housing 510, and its output shaft 121 extends from the housing 510 and into the interior of the mounting base 520, extending longitudinally along the housing 510. The gear 210 is fixedly fitted onto the output shaft 121, and the rack 220 extends laterally along the housing 510 and is connected to the gear. 210 meshing; the output platform 300 includes a longitudinal section 310 and a transverse section 320. The mounting base 520 and the longitudinal section 310 are arranged along the second transverse direction of the housing 510. The gear 210 is disposed inside the mounting base 520, and the rack 220 is disposed in the longitudinal section 310. The longitudinal direction, the first transverse direction, and the second transverse direction of the housing 510 are perpendicular to each other. The transverse section 320, the mounting base 520, and the housing 510 are arranged sequentially along the longitudinal direction of the housing 510. The guide structure 700 is disposed between the mounting base 520 and the output platform 300 to guide the output platform 300 to move along the first transverse direction of the housing 510.

[0044] In this embodiment, the longitudinal direction, the first transverse direction, and the second transverse direction of the housing 510 are three mutually perpendicular directions with the housing 510 as a reference. Specifically, in the figure, the first transverse direction can be represented by the direction indicated by arrow ab, the second transverse direction can be represented by the direction indicated by arrow cd, and the longitudinal direction can be represented by the direction indicated by arrow ef.

[0045] In the following description, the longitudinal direction of the housing 510, the first transverse direction of the housing 510, and the second transverse direction of the housing 510 are referred to as the longitudinal direction, the first transverse direction, and the second transverse direction, respectively.

[0046] When in use, the rotary motor rotates, driving the gears to rotate. Under the meshing transmission action of the gears and rack, the rack outputs a displacement along the first lateral direction, thereby causing the output platform, which is fixedly connected to the rack, to output a displacement along the first lateral direction. Materials or workpieces can be carried by the output platform or connected to the output platform.

[0047] This displacement platform connects the housing and the mounting base longitudinally, mounts the rotary motor inside the housing with its output shaft also longitudinal, and sets the rack and gear to be arranged in the second transverse direction. Because the rack is located in the longitudinal section, the power transmission path during operation is: output shaft - gear - rack - longitudinal section, and the power transmission direction is: longitudinal - second transverse - longitudinal. On the one hand, it transfers the drive components that were originally collinear with the displacement direction of the output platform in the prior art to a direction perpendicular to it, effectively reducing the overall transverse dimension of the displacement platform. On the other hand, embedding the output shaft of the rotary motor and the gear fixedly mounted on the output shaft into the mounting base also achieves a rational layout of components, making the structure of the displacement platform more compact.

[0048] Please continue to refer to Figure 4 In this embodiment, the housing 510 has an installation port, and the mounting base 520 is fixedly connected to the installation port. The mounting base 520 is fixedly connected to the housing 510 via a bottom wall 524, which covers the installation port. The bottom wall 524 has a drive port 5242, through which the output shaft 121 extends into the interior of the mounting base 520.

[0049] Please continue to refer to Figure 4 and Figure 5 In this embodiment, the displacement platform may further include a displacement detection element 400. Specifically, the displacement detection element 400 is disposed between the transverse section 320 and the mounting base 520, and the guide structure 700 is disposed between the mounting base 520 and the longitudinal section 310.

[0050] The displacement detection element 400 enables the detection of the displacement of the output platform 300, ensuring the motion accuracy of the displacement platform in this embodiment. Furthermore, by placing the displacement detection element 400 between the transverse section 320 and the mounting base 520, and the guide structure 700 between the mounting base 520 and the longitudinal section 310, the displacement detection element 400 and the guide structure 700 are positioned in two different locations on the mounting base 520. This achieves efficient use of space while reducing interference between components.

[0051] In other embodiments, the displacement detection element 400 can be positioned between the longitudinal section 310 and the mounting base 520, while the guide structure 700 can be positioned between the mounting base 520 and the transverse section 320. This arrangement not only avoids installation interference between the guide structure 700 and the displacement detection element 400, but also allows the guide structure 700 to provide a connection between the longitudinal section 310 and the mounting base 520, thereby ensuring the structural stability of the displacement platform.

[0052] In this embodiment, the displacement detection element 400 is a linear encoder.

[0053] Please continue to refer to Figure 4 In this embodiment, a detection space 521 is provided on the part of the mounting base 520 facing the transverse section 320, and the displacement detection element 400 is accommodated in the detection space 521.

[0054] The aforementioned detection space 521 accommodates the displacement detection component 400. On the one hand, it protects the displacement detection component 400, and on the other hand, it makes effective use of the internal space of the mounting base 520, making the structure of the displacement platform in this embodiment more compact.

[0055] In the embodiment shown in the accompanying drawings, the top of the mounting base 520 is provided with an opening 530, and the transverse section 320 is located above the opening 530 to cover the opening 530. In other words, the output platform 300 is placed on top of the mounting base 520 to ensure the sealing of the detection space 521.

[0056] Please continue to refer to Figure 4 In this embodiment, the mounting base 520 is provided with a partition 522, which effectively separates the accommodating space 330, so that the displacement detection element 400 and the longitudinal section 310 are respectively located on both sides of the partition 522 and are respectively accommodated by the space on both sides of the partition 522, which reduces the mutual interference between the displacement detection element 400 and the longitudinal section 310, and at the same time improves the structural strength of the mounting base 520.

[0057] Please continue to refer to Figure 4 In this embodiment, the bottom wall 524 of the mounting base 520 is provided with a wiring channel 5241, wherein the wiring channel 5241 connects the detection space 521 and the inner cavity 511 of the housing 510.

[0058] By setting up the wiring channel 5241, the cable connected to the displacement detection component 400 can enter the inner cavity 511 of the housing 510 through the wiring channel 5241, so that the cable connected to the rotary motor 100 can be led out through the housing 510 together. This not only reduces the number of lead holes opened in the housing 510, but also ensures that the appearance of the displacement platform is neat.

[0059] Please continue to refer to Figure 4 In this embodiment, the wiring channel 5241 is parallel to the longitudinal direction, that is, the wiring channel 5241 is a straight channel extending longitudinally. This type of wiring channel 5241 can not only shorten the wiring path, but also avoid bending of the cable during the process of entering the housing 510 from the detection space 521.

[0060] Please continue to refer to Figure 4 In this embodiment, the circuit board 600 of the displacement platform is disposed in the inner cavity 511 of the housing 510, and the circuit board 600 is arranged longitudinally. That is, the circuit board 600 has a rectangular plate structure, and the long side of the circuit board 600 is along the longitudinal direction.

[0061] This arrangement of placing the circuit board 600 longitudinally in the mounting space 511 ensures that the shorter side of the circuit board 600 is arranged laterally, effectively reducing the space occupied by the circuit board 600 in the width direction. This reduces the lateral dimension of the housing 510, thereby achieving the goal of reducing the lateral dimension of the displacement platform.

[0062] Please continue to refer to Figures 4 to 7 In this embodiment, the guide structure 700 includes a slide rail 710 and a slider 720 that slides with the slide rail 710. The slide rail 710 extends along the first transverse direction, that is, the extension direction of the slide rail 710 is the displacement direction of the output platform 300. The slide rail 710 is fixedly disposed on the partition 522, and the slider 720 is fixedly disposed on the longitudinal section 310.

[0063] By setting the aforementioned guide structure 700 between the output platform 300 and the partition 522, the smooth movement of the output platform 300 can be ensured, and jamming during the movement of the output platform 300 can be reduced. Furthermore, by setting the slide rail 710 on the partition 522 and the slider 720 on the output platform 300, the overall weight of the output platform 300 can be reduced, thereby reducing the inertial force during the movement of the output platform 300, which is beneficial for controlling the displacement accuracy of the output platform 300.

[0064] Please continue to refer to Figures 4 to 7 In this embodiment, the longitudinal section 310 of the output platform 300 is provided with two sets of sliders 720 at longitudinal intervals. The two sets of sliders 720 slide and engage with the slide rail 710 on both sides of the slide rail 710. This arrangement not only improves the smoothness of movement of the output platform 300, but also improves the mass distribution of the output platform 300, thereby improving the stability of the output platform 300 during movement.

[0065] Please continue to refer to Figures 4 to 7In this embodiment, the displacement platform may further include a cover plate 800. Specifically, the cover plate 800 is fixedly connected to the mounting base 520, and the cover plate 800 has a limiting opening 810 that is opposite to the transverse segment 320 along the longitudinal direction. The limiting opening 810 includes a first edge 811 and a second edge 812 that are opposite to each other along the first transverse direction, and a third edge 813 and a fourth edge 814 that are opposite to each other along the second transverse direction. A boss 321 is provided on the side of the transverse segment 320 facing the detection space 521. The boss 321 is embedded in the limiting opening 810, and the displacement detection element 400 is disposed between the boss 321 and the mounting base 520.

[0066] During use, when the output platform 300 outputs displacement along the first lateral direction, the boss 321 will move along the first lateral direction in the limiting port 810. By abutting the boss 321 against the first edge 811 and the second edge 812, the boss 321 can be limited in the limiting port 810 along the first lateral direction, thereby achieving the purpose of limiting the output platform 300 along the first lateral direction and preventing the output platform 300 from detaching from the outer shell 500 along the first lateral direction.

[0067] By setting a third edge 813 and a fourth edge 814 opposite to each other along the second lateral direction, the output platform 300 can be limited in the second lateral direction to prevent the output platform 300 from detaching from the housing 500 along the second lateral direction.

[0068] In addition, the limiting port 810 opened in the cover plate 800 to limit the output platform 300 means that the limiting structure of the output platform 300 is arranged longitudinally with the output platform 300 and does not occupy the lateral space, which helps to reduce the lateral dimension of the displacement platform in this embodiment.

[0069] like Figure 8 As shown, in this embodiment, the mounting base 520 may further include a surrounding wall 525. Specifically, the surrounding wall 525 includes a first side wall 5251, a second side wall 5252, and a third side wall 5253 connected in a U-shape. The longitudinal segment 310 is located between the first side wall 5251 and the third side wall 5253 along the first transverse direction. The first side wall 5251 and the third side wall 5253 are used to limit the sliding stroke of the output platform 300 along the first transverse direction.

[0070] This structure, which encloses the mounting base 520 on three sides, allows for the creation of space within the mounting base 520 to effectively accommodate the displacement detection element 400 and the longitudinal section 310. Furthermore, it enables the installation of the guide structure 700 within the open area of ​​the enclosure 525, thus improving the ease of installation and maintenance.

[0071] Please continue to refer to Figure 2 , Figure 6 and Figure 7 In this embodiment, the displacement platform may also include a tension spring 900. Specifically, one end of the tension spring 900 is fixedly connected to the mounting base 520, and the other end of the tension spring 900 is fixedly connected to the output platform 300. The tension spring 900 always has the tendency to drive the output platform 300 to slide along the first lateral direction.

[0072] The aforementioned tension spring 900 provides a tension force in the first lateral direction that is always engaged with the drive gear on the transmission rack, thereby effectively reducing the backlash between the drive gear and the transmission rack and reducing the displacement deviation of the output platform 300 caused by the backlash.

[0073] Please continue to refer to Figure 6 and Figure 7 In this embodiment, the tension spring 900 is located between the first sidewall 5251 and the third sidewall 5253. Please continue to refer to... Figure 4 The tension spring 900 is located below the longitudinal section 310 and along the second transverse direction, the gear 210, the guide structure 700 and the tension spring 900 are arranged in sequence.

[0074] In addition, this embodiment also provides a planar displacement device, such as Figure 9 As shown, the planar displacement device includes two displacement platforms as described above. The mounting base of one displacement platform is mounted on the output platform of the other displacement platform, and the output directions of the two displacement platforms are perpendicular to each other.

[0075] By incorporating the aforementioned displacement platform into the planar displacement device, the planar displacement device acquires all the advantages of the aforementioned displacement platform, which will not be elaborated upon here.

[0076] In addition, by setting two displacement platforms in the planar displacement device and making the output directions of the two displacement platforms perpendicular to each other, the motion of the two displacement platforms can be superimposed, so that when the material or workpiece is carried on the output platform of one of the displacement platforms, the material or workpiece can obtain two-dimensional displacement output on the horizontal plane.

[0077] It should be noted that the output direction of the displacement platform is the direction of displacement of the output platform under the drive of the rotary driver of the displacement platform.

[0078] For ease of description and distinction, the two displacement platforms are defined as the first platform 010 and the second platform 020, respectively. The mounting base 520 of the second platform 020 is mounted on the output platform 300 of the first platform 010.

[0079] Please continue to refer to Figure 9In this embodiment, the planar displacement device may further include an L-shaped adapter 030, which includes a first plate 031 and a second plate 032 that are vertically connected. The first plate 031 is fixedly connected to the output platform 300 of the first platform 010, and the second platform 020 is located in a right-angled space jointly constructed by the first plate 031 and the second plate 032. The second platform 020 is fixedly connected to the first plate 031 through a third side wall 5253 and to the second plate 032 through a second side wall 5252.

Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
