[0018] 4. In the present invention, by providing an adjustment assembly, when the balance plate bears the pressure of the light energy components and causes the first sliding block to start sliding, the first sliding block drives the second sliding block through the second rotating rod, so that the second sliding block slides synchronously along the outer surface of the fixed shaft. Since the second sliding block is connected to the first sliding block through the second rotating rod, the sliding of the second sliding block can ensure that the sliding distance of the first sliding block remains consistent. Furthermore, when the balance plate moves downward due to the weight of the light energy components it bears, it can slide smoothly, thereby enhancing the stability of the light energy components during the transportation process.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] Example 1: Refer to Figures 1 - 3 , Figure 8 , the present invention provides a technical solution: an intelligent handling platform for light energy components, including a first support frame 1. The first support frame 1 includes a first sliding groove 2 opened on the outer surface, and a second sliding groove 3 is opened on the outer surface of the top of the first support frame 1. It also includes: The handling mechanism 4 includes a first rotating frame 401 arranged outside the first support frame 1. A first dual-shaft motor 402 is fixedly connected to the inner wall of the first rotating frame 401. The output end of the first dual-shaft motor 402 is fixedly connected to a driving wheel 403. The driving wheel 403 is in rolling connection inside the first sliding groove 2. A first connecting frame 404 is fixedly connected to the outer wall of the top of the first rotating frame 401. A second dual-shaft motor 406 is fixedly connected to the inner wall of one end of the first connecting frame 404 away from the first rotating frame 401. The output end of the second dual-shaft motor 406 is fixedly connected to a second rotating frame 408. A telescopic arm 409 is fixedly connected to the inner wall of the second rotating frame 408. The output end of the telescopic arm 409 is fixedly connected to a fixing block 413. A winch 407 is fixedly connected to one end of the first connecting frame 404 away from the second dual-shaft motor 406. A lifting rope 417 is wound around the outer surface of the winch 407. An auxiliary mechanism 5 is arranged at one end of the lifting rope 417 away from the winch 407. When carrying out the handling operation of the light energy components, the first dual-shaft motor 402 drives the driving wheel 403 to roll in the first sliding groove 2, thereby driving the first rotating frame 401 to rotate along the outer surface of the support frame towards the direction where the light energy components are located. At the same time, the second dual-shaft motor 406 causes the second rotating frame 408 to flip to a specific angle. The winch 407 lifts the auxiliary mechanism 5 to different heights through the lifting rope 417, thereby realizing the handling of the light energy components at different positions to different required heights.
[0025] An auxiliary wheel 405 is rotatably connected to the outer wall of one side of the first connecting frame 404 close to the second dual-shaft motor 406 through a rotating shaft. The auxiliary wheel 405 is in rotating connection inside the second sliding groove 3. The auxiliary wheel 405 is used to improve the stability of the first connecting frame 404 during the rotation process. An auxiliary motor 414 is fixedly connected to the outer wall of one end of the fixing block 413 away from the telescopic arm 409. The output end of the auxiliary motor 414 penetrates through the fixing block 413 and is fixedly connected to a first rotating block 415. The inner wall of one end of the first rotating block 415 away from the auxiliary motor 414 is in sliding connection with the lifting rope 417. A fixing frame 416 is fixedly connected to the outer wall of one side of the first rotating block 415 close to the fixing block 413. An auxiliary roller 418 is rotatably connected to the inner wall of the fixing frame 416 through a rotating shaft. When carrying out the handling operation of the light energy components at different positions, the auxiliary motor 414 drives the first rotating block 415 to deflect around the connection point, thereby realizing the adjustment of the traction angle of the lifting rope 417. The auxiliary roller 418 effectively reduces the friction between the lifting rope 417 and the fixing frame 416 through its own rolling, providing assistance for the smooth deflection of the angle of the lifting rope 417.
[0026] Example 2: Please refer to Figures 4 - 7, on the basis of Embodiment 1, the present invention provides a technical solution: The auxiliary mechanism 5 includes a lifting frame 501 fixedly connected to the lifting rope 417. The inner wall of the lifting frame 501 is fixedly connected with a second support frame 502. A third sliding groove 503 is formed on the outer surface of the second support frame 502. A fixed shaft 504 is fixedly connected to the inner wall of the second support frame 502. The outer wall of the second support frame 502 is rotatably connected with a second rotating block 505 through a rotating shaft. An adjusting assembly 506 is arranged inside the lifting frame 501. One end of the second rotating frame 408 close to the telescopic arm 409 is fixedly connected with a third double-shaft motor 410. The output end of the third double-shaft motor 410 is fixedly connected with a second connecting frame 411. The inner wall of the end of the second connecting frame 411 away from the third double-shaft motor 410 is fixedly connected with a hydraulic rod 412. The output end of the hydraulic rod 412 is fixedly connected with the second rotating block 505. When the lifting frame 501 unfolds the lifting work of the light energy assembly, the third double-shaft motor 410 adjusts the hydraulic rod 412 to make a deflection action at a corresponding angle according to the actual position of the lifting frame 501. Since the hydraulic rod 412 is firmly connected to the second rotating block 505, the deflection of the hydraulic rod 412 can form an auxiliary support for the side wall of the lifting frame 501, and finally improves the stability of the lifting frame 501 during the handling of the light energy assembly.
[0027] The adjusting assembly 506 includes a balance plate 5061 arranged inside the lifting frame 501. The bottom inner wall of the balance plate 5061 is rotatably connected with a first rotating rod 5062 through a rotating shaft. One end of the first rotating rod 5062 away from the balance plate 5061 is rotatably connected with a first sliding block 5063 through a rotating shaft. The first sliding block 5063 is slidably connected inside the third sliding groove 503. One end of the first sliding block 5063 away from the first rotating rod 5062 is fixedly connected with a first spring 5064. The end of the first spring 5064 away from the first sliding block 5063 is fixedly connected with the second support frame 502. When starting the handling operation of the light energy assembly, first place the light energy assembly on the balance plate 5061. The balance plate 5061 applies pressure to the first sliding block 5063 through the first rotating rod 5062, causing the first sliding block 5063 to slide along the inner wall of the third sliding groove 503 under the action of the pressure and compress the first spring 5064.
[0028] One end of the first sliding block 5063 away from the first rotating rod 5062 is rotatably connected to a second rotating rod 5065 through a rotating shaft. One end of the second rotating rod 5065 away from the first sliding block 5063 is rotatably connected to a second sliding block 5066 through a rotating shaft. The second sliding block 5066 is movably sleeved on the outer surface of the fixed shaft 504. One end of the outer wall of the second sliding block 5066 away from the second rotating rod 5065 is fixedly connected to a second spring 5067. One end of the second spring 5067 away from the second sliding block 5066 is fixedly connected to the second support frame 502. When the balance plate 5061 bears the pressure of the light energy component, the first sliding block 5063 drives the second sliding block 5066 to move along the outer surface of the fixed shaft 504 through the second rotating rod 5065. The movement of the second sliding block 5066 compresses the second spring 5067, and at the same time, through the second rotating rod 5065, the sliding distance of the first sliding block 5063 is synchronized therewith, so as to ensure that the balance plate 5061 slides evenly under the weight of the light energy component, thereby improving the stability of the light energy component during the handling process.
