Detailed Description of the Embodiments

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0027] Embodiment 1

[0028] Refer to Figure 1 、 Figure 2 and Figure 3 As shown, a motion platform of the present utility model includes

[0029] a support base 1;

[0030] a motor 2, the motor 2 includes an X-axis linear motor 21 and a Z-axis linear motor 22 arranged side by side on the support base 1;

[0031] an X-axis slide table assembly 3, the X-axis slide table assembly 3 includes a first slide rail 31 connected to the stator of the Z-axis linear motor 22 along the X-axis direction, a first slider 32 is slidably connected to the first slide rail 31, the first slider 32 is connected to an X-axis slide table 33, and one end of the X-axis slide table 33 is connected to the mover of the X-axis linear motor 21;

[0032] a Z-axis slide table assembly 4, the Z-axis slide table assembly 4 includes a second slide rail 41 connected to the X-axis slide table 33 along the Z-axis direction, a second slider 42 is slidably connected to the second slide rail 41, the second slider 42 is connected to a Z-axis slide table 43, and the Z-axis slide table 43 is connected to the mover of the Z-axis linear motor 22.

[0033] Specifically, the X-axis linear motor 21 can drive the X-axis slide table 33 and the Z-axis slide table connected thereto to move in the X-axis direction. At the same time, the Z-axis linear motor 22 can drive the Z-axis slide table 43 to move in the Z-axis direction. When the two slide tables move in two directions, there is no interference and they cooperate with each other.

[0034] Specifically, the motion platform of the present utility model optimizes the structure, and installs the Z-axis linear motor 22 for driving the movement of the Z-axis slide table 43 on the support base 1 instead of on the X-axis slide table 33. While it can meet the requirement of driving the Z-axis slide table 43 to slide, it also reduces the load on the X-axis slide table 33, that is, reduces the load on the X-axis linear motor 21. In this way, the movement speed of the entire motion platform can be increased, thereby improving production efficiency. And the positions of the X-axis linear motor 21 and the Z-axis linear motor 22 are reasonably arranged and integrated, reducing the volume of the entire platform, making the entire motion platform applicable to a variety of different installation requirements and having high versatility.

[0035] Refer to Figure 2 and Figure 3As shown, further, it includes an X-axis position detection device 5. The X-axis position detection device 5 includes a first grating scale 51 and a first encoder 52. The first grating scale 51 is arranged along the X-axis direction at one end of the X-axis slide 33, and the first encoder 52 is connected to the support base 1 and corresponds to the position of the first grating scale 51.

[0036] Further, it includes a Z-axis position detection device 6. The Z-axis position detection device 6 includes a second grating scale 61 and a second encoder 62. The second grating scale 61 is arranged along the Z-axis direction on the Z-axis slide 43, and the second encoder 62 is connected to the X-axis slide 33 and corresponds to the position of the second grating scale 61. Specifically, by setting the X-axis position detection device 5 and the Z-axis position detection device 6 and cooperating with the control system, the movement positions of the X-axis slide 33 and the Z-axis slide 43 can be monitored in real time to ensure the movement accuracy of the entire movement platform.

[0037] Further, there are two first slide rails 31 arranged at intervals. Between the two first slide rails 31, there are two first stoppers 34 respectively close to both ends thereof, and buffer members are arranged on the opposite surfaces of the two first stoppers 34.

[0038] Further, there are two limit blocks respectively close to both ends connected between the two first sliders 32, and the positions of the limit blocks correspond to the positions of the first stoppers 34. It can be imagined that by setting the first stoppers 34, the movement range of the X-axis slide 33 can be restricted to prevent the X-axis slide 33 from detaching from the first slide rails 31 and ensure the safe progress of production activities.

[0039] Further, one end of the X-axis slide 33 extends to the side of the Z-axis linear motor 22 away from the X-axis linear motor 21 and is provided with two second slide rails 41. The second slide rails 41 are located on the surface of the X-axis slide 33 close to the Z-axis linear motor 22, and there is a second stopper between the ends of the two second slide rails 41 away from the Z-axis linear motor 22. At the same time, there is another second stopper on the side of the Z-axis slide 43 close to the Z-axis linear motor 22. Specifically, the second stopper can play a role in limiting the Z-axis slide 43 to prevent the Z-axis slide 43 from colliding with the Z-axis linear motor 22 and from detaching from the second slide rails 41.

[0040] Refer to Figure 1 As shown, further, first side protection plates 7 are respectively connected to both ends of the stator of the X-axis linear motor 21, and second side protection plates 8 are respectively connected to both ends of the stator of the Z-axis linear motor 22.

[0041] Further, dust-proof bellows 9 are connected between the two second side protection plates 8 and the sides of the X-axis slide 33. Specifically, the first side protection plate 7 and the second side protection plate 8 can respectively protect the X-axis linear motor 21 and the Z-axis linear motor 22, and the dust-proof bellows 9 cooperate with the second side protection plate 8 to play a role in dust prevention.

[0042] Further, the support base 1 includes two parallel mounting plates, and the motor 2 is disposed between the two mounting plates. Specifically, a linear motor generally includes a stator and a rotor, and the stator generally includes two parallel and spaced magnetic plates; in this motion platform, one magnetic plate of the X-axis linear motor 21 and the Z-axis linear motor 22 is integrally provided (i.e., two sets of magnets are spaced on the same plate body, and the other magnetic plates of the X-axis linear motor 21 and the Z-axis linear motor 22 are still separately provided), and the X-axis linear motor 21 is fixed between the two mounting plates, while the position where the Z-axis linear motor 22 is located is outside the two mounting plates, which can be used as the mounting platform of the X-axis slide assembly 3, further reducing the volume of the entire motion platform.

It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
