Figure 3 , the D1 direction is the first direction, and the D2 direction is the second direction.

[0058] like Figures 1 to 5 As shown, the load-bearing device provided by the embodiment of the present invention includes a support platform 1, a load-bearing platform 2, a guide mechanism 3 and a locking mechanism 4. The load-bearing platform 2 is spaced apart from the support platform 1, and the load-bearing platform 2 is used to carry items. The guide mechanism 3 is arranged between the support platform 1 and the load-bearing platform 2. One end of the locking mechanism 4 is connected to the support platform 1, and the other end is connected to the load-bearing platform 2. Among them, the guide mechanism 3 is configured to be able to drive the load-bearing platform 2 to perform linear motion and / or rotational motion, so that the load-bearing platform 2 moves to the target position, and the locking mechanism 4 is configured to be able to lock the load-bearing platform 2 at the target position.

[0059] Specifically, the carrying device includes a supporting platform 1 and a carrying platform 2. The supporting platform 1 is used to be connected and fixed with other components such as a workbench, and the carrying platform 2 is used to carry objects, which may be experimental instruments, testing instruments, workpieces to be tested, etc. The objects are placed on the carrying platform 2 and can be fixed on the carrying platform 2 by screwing, clamping, etc.

[0060] The support platform 1 and the load-bearing platform 2 can be placed in a horizontal state. When placed in a horizontal state, the support platform 1 and the load-bearing platform 2 are spaced apart in the vertical direction. The support platform 1 and the load-bearing platform 2 can also be placed in a vertical state. When placed in a vertical state, the support platform 1 and the load-bearing platform 2 are spaced apart in the horizontal direction. The support platform 1 and the load-bearing platform 2 can also be placed at an angle inclined to the horizontal direction.

[0061] The support platform 1 and the carrying platform 2 can both be plate-like bodies, and the top surfaces of the support platform 1 and the carrying platform 2 must ensure flatness. The support platform 1 is used to support the guide mechanism 3, the locking mechanism 4 and other components, and the support platform 1 can be a triangular plate-like body. The carrying platform 2 is used to carry items, and the carrying platform 2 can be a square plate-like body. According to the use requirements, the support platform 1 and the carrying platform 2 can also be plate-like bodies of other shapes.

[0062] An accommodating space is formed between the supporting platform 1 and the carrying platform 2, and the guide mechanism 3 is located in the accommodating space. The fixed end of the guide mechanism 3 is connected to the supporting platform 1, and the movable end of the guide mechanism 3 is connected to the carrying platform 2. The guide mechanism 3 includes at least one linear motion mechanism and at least one rotation mechanism. The linear motion mechanism can drive the carrying platform 2 to perform linear motion in one direction or multiple directions, and the rotation mechanism can drive the carrying platform 2 to perform rotational motion.

[0063] The linear motion mechanism may include a screw nut transmission mechanism, a synchronous belt transmission mechanism, a gear rack transmission mechanism, an electric push rod, an oil cylinder, an air cylinder, etc. The rotation mechanism may include a gear transmission mechanism, a belt transmission mechanism, a chain transmission mechanism, a crank rocker mechanism, etc.

[0064] The locking mechanism 4 has a first end and a second end opposite to each other, the first end is connected to the supporting platform 1, and the second end is movably connected to the carrying platform 2, and the second end of the locking mechanism 4 can move synchronously with the carrying platform 2. The carrying platform 2 moves to the target position under the guidance of the guide mechanism 3, and the locking mechanism 4 stops moving after synchronously moving to the target position with the carrying platform 2, and the linear motion and rotational motion of the guide mechanism 3 are locked, thereby locking the carrying platform 2 at the target position.

[0065] For ease of description, the following description is based on the example of the carrying platform 2 being placed in a horizontal state. The following description uses a specific embodiment to illustrate the use scenario of the carrying device. Fig.12 As shown, the object is a detection instrument 7, and the carrying platform 2 is used to carry the detection instrument 7. The detection instrument 7 is used to detect the parameters of the light beam emitted by the ray source 8 (such as an optical machine). The optical machine and the carrying device are placed at intervals in the horizontal direction. The angle range of the light beam emitted by the optical machine is 30 to 60 degrees. The detection end of the detection instrument 7 is used to detect the parameters of the light beam.

[0066] The detection instrument 7 is fixed on the carrying platform 2, and the guide mechanism 3 drives the carrying platform 2 to make linear motion in the horizontal direction, which is mainly used to adjust the distance between the detection instrument 7 and the light beam; the guide mechanism 3 drives the carrying platform 2 to make rotational motion around the vertical direction, and by adjusting the angle of the carrying platform 2, the angle of the detection end of the detection instrument 7 is adjusted so that the detection end is opposite to the light beam. After the carrying platform 2 is moved to the target position by the linear motion and rotation of the guide mechanism 3, the carrying platform 2 is locked at the target position by the locking mechanism 4, thereby realizing accurate detection of the parameters of the light beam.

[0067] The guide mechanism 3 drives the carrying platform 2 to perform linear motion and rotational motion. Through the motion with multiple degrees of freedom, the position of the carrying platform 2 can be flexibly adjusted, thereby achieving flexible adjustment of the position of the objects carried by the carrying platform 2.

[0068] In an embodiment of the present invention, the guide mechanism 3 is located between the supporting platform 1 and the carrying platform 2. The carrying platform 2 is used to carry items. The guide mechanism 3 is used to drive the carrying platform 2 to perform linear motion and rotational motion to move the carrying platform 2 to the target position. The locking mechanism 4 is used to lock the carrying platform 2 at the target position. The guide mechanism 3 and the locking mechanism 4 are both integrated between the supporting platform 1 and the carrying platform 2, which can not only realize flexible adjustment of the position of the carrying platform 2, but also have a compact overall structure, which is conducive to the miniaturization of the carrying device.

[0069] In an optional embodiment, the guide mechanism 3 is configured to be able to drive the carrying platform 2 to perform linear motion along a first direction, linear motion along a second direction, and rotational motion around a rotation axis extending along a third direction, so as to move the carrying platform 2 to a target position. The first direction and the second direction intersect, and the third direction is perpendicular to both the first direction and the second direction.

[0070] The carrying platform 2 is placed in a horizontal state, the first direction and the second direction are both parallel to the horizontal direction, and the third direction is parallel to the vertical direction. The guide mechanism 3 rotates around the third direction, and can adjust the angle between the first direction and the second direction, so that the first direction and the second direction are perpendicular to each other, or the first direction and the second direction are at an angle other than 90 degrees. It can be understood that one of the first direction and the second direction is relatively fixed, and the direction of the other of the first direction and the second direction is adjusted by the rotation of the guide mechanism 3 around the third direction, so as to drive the carrying platform 2 to rotate.

[0071] The guide mechanism 3 performs linear motion along the first direction and the second direction, and performs rotational motion around the third direction, ensuring that the guide mechanism 3 has a sufficiently large range of motion. At the same time, the linear motion and rotational motion drive the carrying platform 2 to move, and the position of the carrying platform 2 can be flexibly adjusted.

The rotating mechanism 32 rotates around the rotation axis, driving the carrying platform 2 to rotate. Through the coordinated movement of the first linear motion mechanism 31 and the rotating mechanism 32, flexible adjustment of the position of the carrying platform 2 is achieved.
