[0033] Please refer to Figure 1 and Figure 2 The embodiment of the application provides a cantilever structure of a grading machine, which comprises a first rod 1, a first mounting seat 2, a second rod 3, a second mounting seat 4 and a grabbing assembly 5.

[0034] The first rod 1 extends along a horizontal direction X. The first rod 1 is provided with a first sliding rail 7 extending along the horizontal direction X. The first sliding rail 7 is located at one end of the first rod 1, and the other end of the first rod 1 is used to be connected with a cross beam. The first mounting seat 2 is located at the side of the first rod 1 provided with the first sliding rail 7. The first mounting seat 2 is connected with the first sliding rail 7 through a first sliding block 8.

[0035] The second rod 3 is located at the side of the first mounting seat 2 away from the first rod 1. The second rod 3 extends along a vertical direction Z and adopts a hollow structure, which can reduce the weight and create conditions for adopting an integrated cantilever. The vertical direction Z is perpendicular to the horizontal direction X. The second rod 3 is provided with a second sliding rail 9 extending along the vertical direction Z at the side facing the first mounting seat 2. The first mounting seat 2 is connected with the second sliding rail 9 through a second sliding block 10.

[0036] The second mounting seat 4 is rotationally connected to the bottom of the second rod 3. The rotation axis of the second mounting seat 4 extends along the vertical direction Z. The grabbing assembly 5 is rotationally connected to the bottom of the second mounting seat 4. The rotation axis of the grabbing assembly 5 extends along the horizontal direction X. The side of the grabbing assembly 5 away from the second mounting seat 4 is provided with a plurality of suction cups 51 for sucking photovoltaic modules.

[0037] The cantilever structure of the grading machine provided by the embodiment includes a first rod 1, a first mounting seat 2, a second rod 3, a second mounting seat 4, and a grabbing assembly 5. The first rod 1 extends along a horizontal direction X and adopts an integrated cantilever, which can greatly reduce the workload of assembly and processing, and at the same time can reduce the workload of welding. Replacing the spliced cantilever with an integrated cantilever can reduce the connecting block for connecting the cantilever (i.e. the first rod 1) with the cross beam, and improve the assembly integration.

[0038] In the embodiment, the first rod 1 is made by an integral molding process, thereby forming an integrated cantilever.

[0039] As shown in Figure 2 The first mounting seat 2 is connected with a first driving member 11 for driving the first mounting seat 2 to move relative to the first rod 1 along the horizontal direction X. The first driving member 11 preferably adopts a screw rod in the form of a small motor, which is conducive to weight reduction, thereby realizing the structure of an integrated cantilever.

[0040] Specifically, the second rod 3 is connected with a second driving member 12 for driving the second rod 3 to move relative to the first rod 1 along the vertical direction Z. The second driving member 12 can be selected from a linear motor.

[0041] As shown in Figure 1 and Figure 2As shown, the second mounting base 4 is connected with a third driving member 13 for driving the second mounting base 4 to rotate relative to the second rod member 3 around the vertical direction Z. The third driving member 13 can be a rotary motor. The second rod member 3 is provided with a first opening 31 for accommodating the third driving member 13, so as to optimize the spatial distribution of the cantilever structure.

[0042] Specifically, the second mounting base 4 includes a first connecting plate 41 and two second connecting plates 42, and the two second connecting plates 42 are located at both ends of the first connecting plate 41 in the horizontal direction X. The grabbing assembly 5 is provided with two third connecting plates 52 on the side close to the second mounting base 4, and the two third connecting plates 52 are respectively rotationally connected with the two second connecting plates 42.

[0043] Further, the third connecting plate 52 is connected with a fourth driving member 14 for driving the third connecting plate 52 to drive the grabbing assembly 5 to rotate relative to the second connecting plate 42 around the horizontal direction X. The fourth driving member 14 can be a rotary motor. The first connecting plate 41 and the two second connecting plates 42 form a second opening 43 for accommodating the fourth driving member 14, so as to optimize the spatial distribution of the cantilever structure.

[0044] In the embodiment, an electrical box 6 is fixed above the first rod member 1, and the electrical box 6 and the first sliding rail 7 are respectively located at both ends of the first rod member 1 along the horizontal direction X. The electrical box 6 can move together with the first rod member 1, so as to optimize the wiring.

[0045] In the embodiment, the material of the second rod member 3 is aluminum, so as to reduce the weight and facilitate the realization of the structure of the integrated cantilever.

[0046] It should be noted that in the description of the present specification, the terms "first", "second" and the like are only used for the purpose of description and distinguishing similar objects, and there is no prior and posterior order between them, nor can it be understood as indicating or implying relative importance. In addition, in the description of the present specification, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0047] Any numerical values ​​cited herein include all values ​​ranging from a lower limit to an upper limit, increasing by one unit, with at least two units between any lower and any higher value. For example, if the quantity of a component or the value of a process variable (e.g., temperature, pressure, time, etc.) is described as being from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, the purpose is to illustrate that values ​​such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly listed in this specification. For values ​​less than 1, a unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1, etc. These are merely examples intended for explicit expression, and it can be assumed that all possible combinations of values ​​listed between the minimum and maximum values ​​are explicitly described in this specification in a similar manner.

[0048] Unless otherwise stated, all ranges include the endpoints and all numbers between them. The terms "approximately" or "about" used with ranges apply to both endpoints of the range. Thus, "approximately 20 to 30" is intended to cover "approximately 20 to approximately 30," including at least the specified endpoints.

[0049] All articles and references disclosed herein, including patent applications and publications, are incorporated herein by reference for various purposes. The term “substantially constitutes…” used to describe a combination should include the identified elements, components, parts, or steps, as well as other elements, components, parts, or steps that do not substantially affect the essential novelty of the combination. The use of the terms “comprising” or “including” to describe combinations of elements, components, parts, or steps herein also contemplates embodiments substantially constituted by such elements, components, parts, or steps. The use of the term “may” herein is intended to indicate that any described attribute included by “may” is optional.

Alternatively, a single integrated element, component, part, or step can be divided into multiple separate elements, components, parts, or steps. The use of "a" or "an" to describe an element, component, part, or step does not imply the exclusion of other elements, components, parts, or steps.

[0051] It is to be understood that the above description is intended to be illustrative, and not restrictive. Many embodiments and many applications other than the examples provided would be apparent upon reading the above description. The scope of the teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
