[0043] A first conveying and positioning assembly is used to convey and position the crossflow blade 1;

[0044] A second conveying and positioning component is used to convey and position the bottom shell 2;

[0045] The grabbing assembly 3 is used to clamp the positioned crossflow blade 1 and assemble it onto the positioned bottom shell 2 .

[0046] In the embodiment, the assembling device is used for assembling the cross-flow fan blade 1 and the bottom shell 2, and the assembling device comprises a first conveying and positioning assembly, a second conveying and positioning assembly, and a grabbing assembly 3.

Compared with the manual assembly, the assembling device has high assembly production efficiency, reduces the labor intensity, has high quality stability, and reduces the labor cost.

[0047] In some embodiments, the first conveying and positioning assembly comprises a first conveying assembly 4, and the first conveying assembly 4 comprises a first driving unit 41 and a first conveying belt 42.

[0048] In the embodiment, the first conveying assembly 4 of the first conveying and positioning assembly comprises the first driving unit 41 and the first conveying belt 42. The first driving unit 41 can be a driving device such as a motor. The first driving unit 41 can drive the first conveying belt 42 to move. For example, a driving shaft of the motor drives the first conveying belt 42 to move. Therefore, the worker places the cross-flow fan blade 1 on the first conveying belt 42. The first conveying belt 42 can convey the cross-flow fan blade 1 on the first conveying belt 42 to the first preset position, so as to complete automatic feeding of the cross-flow fan blade 1. Then, the grabbing assembly 3 clamps and conveys the cross-flow fan blade 1 at the first preset position, so as to facilitate subsequent assembly processes such as accurate positioning.

[0049] In some embodiments, the first conveying assembly 4 further comprises a first support 43 and at least two first rollers rotatably arranged on the first support 43. The first conveying belt 42 is arranged around the at least two first rollers. The first driving unit 41 is arranged on the first support 43 and can drive at least one first roller to rotate.

[0050] In the embodiment, the first support 43 of the first conveying assembly 4 is provided with at least two first rollers which are arranged in rotation, the axes of the at least two first rollers are arranged horizontally, and the axes of the at least two first rollers are arranged in parallel, the first conveying belt 42 is arranged around the at least two first rollers, and the first driving unit 41 is arranged on the first support 43 and can drive the at least one first roller to rotate.

[0051] In some embodiments, the first support 43 is provided with a baffle plate 431 on at least one side in the length direction of the first conveying belt 42, and the baffle plate 431 is provided with a material blocking structure 432 at the end in the conveying direction of the first conveying belt 42, which can block the cross-flow fan blade 1.

[0052] In the embodiment, the first support 43 is provided with a baffle plate 431 on at least one side in the length direction of the first conveying belt 42, and the baffle plate 431 is provided with a material blocking structure 432 at the end in the conveying direction of the first conveying belt 42, which can block the cross-flow fan blade 1.

[0053] In some embodiments, the baffle plate 431 is provided with a first sensing unit 433 at the end of the conveying stroke of the first conveying belt 42, which can sense that the cross-flow fan blade 1 is blocked by the material blocking structure 432.

[0054] In the embodiment, the baffle plate 431 is provided with a first sensing unit 433 at the end of the conveying stroke of the first conveying belt 42, which can sense that the cross-flow fan blade 1 is blocked by the material blocking structure 432. When the cross-flow fan blade 1 on the first conveying belt 42 is conveyed to the first preset position and is preliminarily positioned, the first sensing unit 433 can sense the cross-flow fan blade 1 on the first preset position, at which time the first driving unit 41 can be controlled to stop, so as to prevent the cross-flow fan blade 1 on the first preset position from being damaged due to long-term friction with the first conveying belt 42.

[0055] The first conveying assembly 4 has its own control system and a start key connected to the control system.

The axial end of the cross-flow fan blade 1 in the positioning groove 511 is abutted against the shoulder 512 by the retractable part of the first retractable unit 52, so as to accurately position the cross-flow fan blade 1. The various parameters of the positional relationship between the cross-flow fan blade 1 and the cross-flow fan blade 1 after accurate positioning can be obtained in advance, so as to ensure the assembly accuracy of the cross-flow fan blade 1 and the bottom shell 2.
