[0076] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures and technologies are proposed in order to thoroughly understand the implementation modes of the present utility model. However, those skilled in the art should clearly understand that the present utility model can also be implemented in other implementation modes without these specific details. In other cases, detailed descriptions of well-known systems, devices, and methods are omitted to avoid unnecessary details from interfering with the description of the present utility model.

[0077] In order to make the purpose, technical solution, and advantages of the present utility model clearer, the following will be described through specific implementation modes in conjunction with the accompanying drawings.

[0078] The following will give a detailed description of the embodiments of the present utility model. This example is implemented on the premise of the technical solution of the present utility model, and detailed implementation modes and specific operation processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.

[0079] A first aspect of the implementation mode of the present utility model provides a jacking and conveying assembly, including:

[0080] A first frame 110, a second frame 120, a jacking mechanism, a first conveyor belt, and an electric roller 150;

[0085] Exemplarily, such as Figure 1As shown in the figure, the figure shows an application scenario diagram of the jacking conveyor component and the cross conveyor device of the present utility model. In the figure, multiple servers are being conveyed on the assembly line conveyor belt 310, and these servers need to be transferred to the test equipment 330 located on both sides of the assembly line. After the test equipment 330 finishes the test, they need to return to the assembly line conveyor belt 310 and continue to flow to the subsequent process. Since the test process of the test equipment 330 is slower than the flow process of the assembly line conveyor belt 310, generally, multiple test equipment 330 need to cooperate with one assembly line conveyor belt 310. The embodiment of the present utility model aims to propose a device that can receive the servers on the assembly line conveyor belt 310, transfer the servers to the test equipment 330, and transfer them back to the assembly line conveyor belt 310 after the test is completed. In other words, it is a cross conveyor device 320 that, on the one hand, receives the servers from the assembly line conveyor belt and, on the other hand, transfers these servers to the test equipment on one side.

In addition to including the lifting and conveying assembly, it further includes a second conveyor belt that is horizontally perpendicular to it. This conveyor belt is composed of two parallel-running belts that are perpendicular to the first conveyor belt. When the first conveyor belt is lifted, it is higher than the second conveyor belt and is used to receive servers from the assembly line. When the first conveyor belt drops, it is lower than the second conveyor belt and is used to transfer the servers from the assembly line to the second conveyor belt.
