DETAILED DESCRIPTION

[0020] The following description is used to disclose the present patent so that those skilled in the art can implement the present patent. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0021] Reference Figure 1-4 As shown, a box changing device based on a double-axis cylinder comprises a bottom plate 1, a mounting block 101 is arranged at the bottom end of the bottom plate 1, a box delivery mechanism 2 is arranged at the top end of the bottom plate 1, a box unloading platform 6 is arranged at the position of the left side of the box delivery mechanism 2 corresponding to the box receiving mechanism 5, a box preparation mechanism 3 is arranged at the top end of the box delivery mechanism 2, a box changing mechanism 4 is arranged at the top right side of the bottom plate 1, a box receiving mechanism 5 is arranged at the top left side of the bottom plate 1, the box changing mechanism 4 comprises a first double-axis cylinder 401, a first movable box 402 is arranged at the telescopic end of the first double-axis cylinder 401, and the first movable box 402 The left side is provided with the same rotating shaft 304, baffle 305 and first motor 306 mechanism as in the preparation box mechanism 3, a sleeve rod 403 is rotatably provided on the inner side of the first movable box 402, a rotating rod 405 is rotatably installed inside the sleeve rod 403, a first movable plate 404 is provided on the outer surface of the sleeve rod 403, a second movable plate 406 is provided on the outer surface of the rotating rod 405, and the second movable plate 406 is slidably installed on the outer surface of the sleeve rod 403, and one end of the sleeve rod 403 and the rotating rod 405 are both highly installed with the output end of the second motor 407.

[0022] In this solution, the first movable box 402 is driven to move by the telescopic end of the first double-axis cylinder 401, and the sleeve rod 403 and the rotating rod 405 are driven by the second motor 407. Through the coordinated action of the first movable plate 404 and the second movable plate 406, the angle can be flexibly adjusted to achieve precise grasping and transportation of the box, thereby improving the box changing efficiency, ensuring the accuracy and stability of the operation, and realizing the function of automatic box changing.

[0023] Reference Figure 1-3 As shown, a box receiving plate 201 is provided inside the box delivery mechanism 2, and a plurality of groups of first rollers 202 are rotatably mounted inside the box receiving plate 201.

[0024] In this solution, the base plate 1 is firmly mounted on the mobile platform by means of the mounting block 101, providing a solid foundation for the entire box changing system. A box receiving plate 201 is arranged in the box delivery mechanism 2 at the top of the base plate 1, and multiple groups of first rollers 202 rotatably mounted thereon can effectively reduce the friction force when the box moves, so that the box can smoothly slide in or out of the box receiving position, thereby achieving stability and smoothness in the box transmission.

[0025] Reference Figure 1-3As shown, the box preparation mechanism 3 includes a frame 301, which is arranged at the top of the box delivery mechanism 2, and a box inlet 302 is opened on the rear side of the frame 301. A plurality of second rollers 303 are arranged at the inner top of the frame 301, and three groups of rotating shafts 304 are rotatably installed at the inner bottom of the frame 301. The outer surfaces of the three groups of rotating shafts 304 are all provided with baffles 305, and one end of the three groups of rotating shafts 304 is fixedly installed with the output end of the first motor 306, and one side of the three groups of baffles 305 is in contact with the collection box.

[0026] In this solution, the provision of the box preparation mechanism 3 greatly improves the storage and transportation efficiency of the boxes. The box inlet 302 on the rear side of the frame 301 facilitates the rapid introduction of new boxes into the system, while the multiple sets of second rollers 303 at the top of the interior further promote the smooth movement of the boxes. What is more ingenious is that the three sets of rotating shafts 304 at the bottom end of the interior of the frame 301 and the baffles 305 thereon can flexibly adjust their positions under the drive of the first motor 306 to fit closely to collection boxes of different sizes, thereby ensuring the stability and safety of the boxes during storage and realizing compatible storage and automatic adjustment of boxes of different specifications.

[0027] Reference Figure 1-3 As shown, the box connection mechanism 5 includes a second double-axis cylinder 501, a second movable box 502 is arranged at the top of the second double-axis cylinder 501, and the left and right sides of the second movable box 502 are both provided with the same rotating shaft 304, baffle 305 and first motor 306 mechanism in the box preparation mechanism 3.

[0028] In this solution, the box receiving mechanism 5, as the terminal link of the entire system, also adopts the design of being driven by the second double-axis cylinder 501, and cooperates with the same rotating shaft 304, baffle 305 and first motor 306 as those in the box preparation mechanism 3, to ensure the smooth reception and placement of the box during the box changing process. This design not only enhances the overall coordination of the system, but also further improves the continuity and reliability of the box changing operation, and realizes a seamless connection from box storage to box receiving.

[0029] The working principle of this patent is as follows: when working, the box inlet 302 of the box preparation mechanism 3 introduces a new box, and the box moves smoothly under the action of multiple sets of second rollers 303 at the top of the frame 301. The three sets of rotating shafts 304 at the bottom of the frame 301 and the baffles 305 thereon are flexibly adjusted to fit the collection box tightly under the drive of the first motor 306 to ensure stable storage of the box. When the box needs to be replaced, the telescopic end of the first double-axis cylinder 401 drives the first movable box 402 to move to the box preparation mechanism 3. The sleeve rod 403 and the rotating rod 405 are driven by the second motor 407 to flexibly adjust the angle through the coordinated action of the first movable plate 404 and the second movable plate 406 to accurately grab the box. After grabbing, the first movable plate 404 and the second movable plate 406 are driven by the second motor 407 to adjust the angle flexibly to accurately grab the box. The box 402 moves to an appropriate position, ready to be transported to the box receiving mechanism 5. At the same time, the second double-axis cylinder 501 of the box receiving mechanism 5 drives the second movable box 502 to move to the box receiving position. The rotating shaft 304 and the baffle 305 thereon adjust their positions under the drive of the first motor 306, ready to receive the box. After the first movable box 402 transports the box to the box receiving mechanism 5, the baffle 305 on the second movable box 502 fits tightly against the box to ensure that the box is placed stably. During the box transmission process, the box receiving plate 201 in the box delivery mechanism 2 and the multiple sets of first rollers 202 rotatably installed thereon effectively reduce the friction when the box moves, so that the box can slide smoothly in or out of the box receiving position, ensuring the stability and smoothness of the box transmission.

The technicians in this industry should understand that this patent is not limited to the above embodiments. The above embodiments and the description only describe the principles of this patent.
