It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[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 seat 520, a rotary motor 110, a gear 210, a rack 220, an output platform 300 and a guide structure 700, wherein the mounting seat 520 is fixedly connected to the housing 510 outside the housing 510; the rotary motor 110 is accommodated in the housing 510, and the output shaft 121 of the rotary motor 110 extends from the housing 510 and extends into the interior of the mounting seat 520, and the output shaft 121 extends in the longitudinal direction of the housing 510; the gear 210 is fixedly sleeved on the output shaft 121, and the rack 220 extends in the first transverse direction of the housing 510 and is connected to the gear 210 is engaged; the output platform 300 includes a longitudinal section 310 and a transverse section 320, the mounting seat 520 and the longitudinal section 310 are arranged along the second transverse direction of the shell 510, the gear 210 is arranged inside the mounting seat 520, the rack 220 is arranged in the longitudinal section 310, the longitudinal direction, the first transverse direction and the second transverse direction of the shell 510 are perpendicular to each other, the transverse section 320, the mounting seat 520 and the shell 510 are arranged in sequence along the longitudinal direction of the shell 510; the guide structure 700 is arranged between the mounting seat 520 and the output platform 300, so as to guide the output platform 300 to move along the first transverse direction of the shell 510.

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

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

[0046] When the displacement platform is in use, the rotary motor rotates to drive the gear to rotate, and under the meshing transmission of the gear and the rack, the rack outputs a displacement along the first lateral direction, so that the output platform fixedly connected to the rack outputs a displacement along the first lateral direction. The material or workpiece can be carried by the output platform or connected to the output platform.

[0047] The displacement platform is connected by arranging the shell and the mounting seat along the longitudinal direction, installing the rotating motor in the inner cavity of the shell and making the output shaft of the rotating motor also along the longitudinal direction, and arranging the rack with the gear along the second transverse direction. Since the rack is arranged in the longitudinal section, the power transmission path of the displacement platform during operation is: output shaft-gear-rack-longitudinal section, and the power transmission direction is: longitudinal-second transverse-longitudinal. On the one hand, the driving component originally arranged in line with the displacement direction of the output platform in the prior art is transferred to a direction perpendicular to it, which effectively reduces the overall transverse size of the displacement platform. On the other hand, the output shaft of the rotating motor and the gear fixedly mounted on the output shaft are embedded in the mounting seat, which also realizes the rational layout of the 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 a mounting opening, and the mounting seat 520 is fixedly connected at the position of the mounting opening. The mounting seat 520 is fixedly connected to the housing 510 through a bottom wall 524, and the bottom wall 524 covers the mounting opening; the bottom wall 524 is provided with a driving opening 5242, and the output shaft 121 extends into the interior of the mounting seat 520 through the driving opening 5242.

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

[0050] The arrangement of the displacement detection member 400 can detect the displacement of the output platform 300 to ensure the motion accuracy of the displacement platform of this embodiment. In addition, by arranging the displacement detection member 400 between the transverse section 320 and the mounting seat 520, and the guide structure 700 between the mounting seat 520 and the longitudinal section 310, the displacement detection member 400 and the guide structure 700 are arranged at two different positions of the mounting seat 520, which not only realizes the rational use of space, but also reduces the mutual interference between components.

[0051] In other embodiments, the displacement detection member 400 may be disposed between the longitudinal section 310 and the mounting seat 520, and the guide structure 700 may be disposed between the mounting seat 520 and the transverse section 320. This arrangement can not only avoid installation interference between the guide structure 700 and the displacement detection member 400, but also utilize the guide structure 700 to play a certain role in connecting the longitudinal section 310 and the mounting seat 520, so as to ensure the structural stability of the displacement platform.

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

[0053] Please continue to refer to Figure 4 In this embodiment, a detection space 521 is provided at a portion of the mounting seat 520 facing the transverse section 320 , and the displacement detecting member 400 is accommodated in the detection space 521 .

[0054] The setting of the above-mentioned detection space 521 realizes the accommodation of the displacement detection member 400. On the one hand, it can protect the displacement detection member 400. On the other hand, it can also realize the effective use of the internal space of the mounting seat 520, making the structure of the displacement platform of this embodiment more compact.

[0055] In the scheme shown in the drawings of this embodiment, an opening 530 is provided at the top of the mounting seat 520, and the transverse section 320 is located above the opening 530 to cover the opening 530. That is, the output platform 300 is covered on the top of the mounting seat 520, thereby ensuring the closedness of the detection space 521.

[0056] Please continue to refer to Figure 4 In this embodiment, a partition 522 is provided inside the mounting seat 520 to achieve effective separation of the accommodating space 330, so that the displacement detecting member 400 and the longitudinal section 310 are arranged on both sides of the partition 522 and are respectively accommodated by the space on both sides of the partition 522, thereby reducing the mutual interference between the displacement detecting member 400 and the longitudinal section 310 and improving the structural strength of the mounting seat 520.

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

[0058] By providing the wiring channel 5241, the cable connected to the displacement detecting member 400 can enter the inner cavity 511 of the shell 510 through the wiring channel 5241, and can be led out through the shell 510 together with the cable connected to the rotating motor 100. This can not only reduce the number of lead holes opened in the shell 510, but also ensure the neat appearance of the displacement platform.

[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 in the longitudinal direction. This arrangement of the wiring channel 5241 can not only shorten the wiring path, but also avoid bending of the cable when it enters 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 in the longitudinal direction. That is, the circuit board 600 is a rectangular plate structure, and the long side of the circuit board 600 is in the longitudinal direction.

[0061] This form of placing the circuit board 600 vertically in the installation space 511 allows the circuit board 600 to be arranged horizontally with its short side, effectively reducing the occupancy of the circuit board 600 along the width direction, thereby reducing the horizontal size of the shell 510, thereby achieving the purpose of reducing the horizontal size 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 slidably matched with the slide rail 710, and 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, wherein the slide rail 710 is fixedly arranged on the partition 522, and the slider 720 is fixedly arranged on the longitudinal section 310.

[0063] By providing the guide structure 700 between the output platform 300 and the partition 522, the smoothness of the movement of the output platform 300 can be ensured, and the jamming during the movement of the output platform 300 can be reduced. In addition, by providing 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 inertia force during the movement of the output platform 300, which is conducive to controlling the displacement accuracy of the output platform 300.

[0064] Please continue to refer to Figures 4 to 7 In this embodiment, two groups of sliders 720 are arranged at intervals along the longitudinal direction of the longitudinal section 310 of the output platform 300, and the two groups of sliders 720 are respectively slidably matched with the slide rail 710 on both sides of the slide rail 710. This arrangement can not only improve the smoothness of the movement of the output platform 300, but also improve the mass distribution of the output platform 300, so as to improve the stability of the output platform 300 during the 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 seat 520, and the cover plate 800 has a limiting opening 810 opposite to the transverse section 320 along the longitudinal direction, and the limiting opening 810 includes a first edge 811 and a second edge 812 arranged opposite to each other along the first transverse direction, and a third edge 813 and a fourth edge 814 arranged opposite to each other along the second transverse direction; a boss 321 is provided on one side of the transverse section 320 facing the detection space 521, and the boss 321 is embedded in the limiting opening 810, and the displacement detection member 400 is arranged between the boss 321 and the mounting seat 520.

[0066] During use of the displacement platform, when the output platform 300 outputs a displacement along the first transverse direction, the boss 321 will move along the first transverse direction in the limiting opening 810. The boss 321 can be limited in the first transverse direction in the limiting opening 810 by abutting against the first edge 811 and the second edge 812, thereby achieving the purpose of limiting the output platform 300 along the first transverse direction and preventing the output platform 300 from detaching from the housing 500 along the first transverse direction.

[0067] By providing the third edge 813 and the fourth edge 814 opposite to each other in the second transverse direction, the output platform 300 can be limited in the second transverse direction to prevent the output platform 300 from being separated from the housing 500 in the second transverse direction.

[0068] In addition, this form of limiting the output platform 300 by using the limiting opening 810 opened in the cover plate 800 allows the limiting structure of the output platform 300 to be arranged longitudinally with the output platform 300 without occupying lateral space, which is beneficial to reducing the lateral size of the displacement platform of this embodiment.

[0069] like Figure 8 As shown, in this embodiment, the mounting seat 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 which are connected in sequence in a U-shape, wherein the longitudinal section 310 is located between the first side wall 5251 and the third side wall 5253 along the first transverse direction, and 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 in which the surrounding wall 525 of the mounting seat 520 is surrounded on three sides can, on the one hand, construct a corresponding space in the mounting seat 520 to effectively accommodate the displacement detection member 400 and the longitudinal section 310. On the other hand, the open area of ​​the surrounding wall 525 can also be used to install the guide structure 700, thereby improving the convenience of installation and maintenance.

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

[0072] The arrangement of the tension spring 900 can provide the transmission rack with a pulling force in the first lateral direction for always engaging with the driving gear, thereby effectively reducing the backlash between the driving 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 side wall 5251 and the third side wall 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 plane displacement device, such as Fig. 9 As shown, the plane displacement device includes two displacement platforms mentioned above. Among 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.

[0075] By arranging the above-mentioned displacement platform in the plane displacement device, accordingly, the plane displacement device has all the advantages of the above-mentioned displacement platform, which will not be described one by one here.

[0076] In addition, by arranging two of the above-mentioned displacement platforms in the plane displacement device and making the output directions of the two displacement platforms perpendicular to each other, and utilizing the motion superposition of the two displacement platforms, when the material or workpiece is carried on the output platform of one of the displacement platforms, the material or workpiece can obtain a two-dimensional displacement output on the horizontal plane.

[0077] It should be noted that the output direction of the displacement platform is: the displacement direction of the output platform of the displacement platform driven by the rotation driver of the displacement platform.

[0078] In the following text, for the convenience of description and distinction, the two displacement platforms are respectively defined as a first platform 010 and a second platform 020 . Among them, the mounting seat 520 of the second platform 020 is mounted on the output platform 300 of the first platform 010 .
