[0095] In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, and methods are omitted to avoid obscuring the description of the present invention with unnecessary detail.

[0096] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will be described through specific implementation methods in conjunction with the accompanying drawings.

[0097] The following is a detailed description of an embodiment of the present invention. This example is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.

[0098] A first aspect of the present invention provides a server lift, comprising:

[0099] Main frame 110, first power device 120, first rotating shaft 130, four sets of sprocket assemblies and transmission device;

[0100] The body of the first power device 120 is fixedly disposed above the body frame 110, the first rotating shaft 130 is horizontally disposed above the body frame 110 and is rotatably connected to the body frame 110, and the output shaft of the first power device 120 is driven by the first rotating shaft 130;

[0101] The four sets of sprocket assemblies each form a chain ring, and the four sets of sprocket assemblies are all driven by the first rotating shaft 130. The four connection points of the transmission device are respectively fixedly connected to the chains of the four sets of sprocket assemblies;

[0102] When the first rotating shaft 130 rotates, the four sets of sprocket assemblies rotate synchronously to drive the conveying device to rise or fall.

[0103] For example, this embodiment of the utility model utilizes four sprocket assemblies to drive the conveyor to rise and fall, thereby transporting the servers. The conveyor supports the servers and moves them horizontally in two dimensions, while the four sprocket assemblies ensure the smooth rise and fall of the conveyor.

[0104] To achieve this, the four sprocket assemblies in this utility model are synchronized via the first rotating shaft 130, and the four sections of the conveyor are fixed to the four sprocket assemblies. This ensures that the four fixed ends of the conveyor rise and fall the same distance each time, ensuring smooth ascent and descent of the server. Furthermore, this embodiment of the utility model does not require a guide rail, making installation and commissioning more convenient.

[0105] In some embodiments, the four sets of sprocket assemblies include a first sprocket assembly, a second sprocket assembly, a third sprocket assembly, and a fourth sprocket assembly;

[0106] The first sprocket assembly and the second sprocket assembly respectively include: a first sprocket 141, a second sprocket 142 and a first chain 143, wherein the first chain 143 is an endless chain;

[0107] The first sprocket 141 is coaxially fixedly connected to the first rotating shaft 130 , the second sprocket 142 is disposed at the bottom of the main frame 110 and is rotatably connected to the main frame 110 , and the first chain 143 surrounds the first sprocket 141 and the second sprocket 142 ;

[0108] The transmission device is arranged on the same side of the first sprocket assembly and the second sprocket assembly, and the transmission device is fixedly connected to the first chain 143 of the first sprocket assembly and the first chain 143 of the second sprocket assembly respectively;

[0109] The third sprocket assembly and the fourth sprocket assembly respectively constitute chain rings and are respectively fixedly connected to the transmission device. The third sprocket assembly and the fourth sprocket assembly are respectively driven by the first rotating shaft 130.

[0110] In some embodiments, the third sprocket assembly and the fourth sprocket assembly respectively include: a third sprocket 144, a fourth sprocket 145, a fifth sprocket 146, a sixth sprocket 147 and a second chain 148, wherein the second chain 148 is an endless chain;

[0111] The third sprocket 144 is coaxially fixedly connected to the first rotating shaft 130. The fourth sprocket 145 is disposed above the main frame 110 and is rotatably connected to the main frame 110. The fifth sprocket 146 and the sixth sprocket 147 are respectively disposed below the main frame 110 and are rotatably connected to the main frame 110. The second chain 148 surrounds the third sprocket 144, the fourth sprocket 145, the fifth sprocket 146, and the sixth sprocket 147.

[0112] The transmission device is disposed inside the chain rings of the second chain 148 of the third sprocket assembly and the second chain 148 of the fourth sprocket assembly, and the transmission device is fixedly connected to the second chain 148 of the third sprocket assembly and the second chain 148 of the fourth sprocket assembly.

[0113] In some embodiments, the chains of the four sprocket assemblies are roller chains.

[0114] For example, in the four sets of sprocket assemblies of the present invention, the first set of sprocket assemblies has the same structure as the second set of sprocket assemblies, and is located on one side of the conveying device. The conveying device is driven to rise and fall by a rotating ring chain, while the third set of sprocket assemblies has the same structure as the fourth set of sprocket assemblies. After the chain crosses the conveying device, it completes the loop, and the connection points of the third set of sprocket assemblies and the fourth set of sprocket assemblies with the conveying device are also located on the same side, thereby completing synchronous lifting and lowering.

[0115] In some application scenarios, the chain uses a roller chain, which runs smoothly and has less resistance, ensuring smooth operation and the safety of the equipment.

[0116] In some embodiments, a plurality of photoelectric sensors 149 are fixedly installed at intervals in the vertical direction of the main frame 110 .

[0117] For example, photoelectric sensors 149 are provided at some pre-set heights on the main frame 110. When the shading material fixed on the chain runs to the position of the photoelectric sensor 149, an indication can be output. When the indication is received, the operation of the sprocket assembly is stopped, and the conveying device can be docked at the position of the photoelectric sensor 149. In some scenarios, test equipment is provided at these positions. At this time, the server can be conveyed to the test equipment through the conveying device, which means that the transfer of the server is completed, with high positioning accuracy and higher transfer efficiency.

[0118] like Figure 7-10 As shown, the transmission device of the embodiment of the utility model includes:

[0119] A first frame 210, a second frame 220, a lifting mechanism, a first conveyor belt, a second conveyor belt, and a motorized roller 250;

[0120] The first frame 210 is disposed above the second frame 220 , and the first frame 210 and the second frame 220 are vertically slidably connected;

[0121] The main body of the jacking mechanism is fixedly connected to the second frame 220, and the telescopic end of the jacking mechanism is fixedly connected to the first frame 210;

[0122] The first conveyor belt is horizontally fixed on the upper surface of the first frame 210;

[0123] The roller of the motorized roller 250 is fixedly connected to the first frame 210 , and the motorized roller 250 is arranged at intervals on the conveying side of the first conveyor belt and at the same height as the first conveyor belt.

[0124] The second conveyor belt includes: a conveyor roller assembly, a third belt 320 and a fourth belt 330;

[0125] The body of the conveyor roller assembly is fixedly connected to the second frame 220, and the third belt 320 and the fourth belt 330 are respectively arranged on both sides of the conveying direction of the first conveyor belt. The third belt 320 and / or the fourth belt 330 are arranged in the interval between the motorized roller 250 and the first conveyor belt;

[0126] The conveying roller assembly drives the third belt 320 and the fourth belt 330 to rotate synchronously;

[0127] When the telescopic end of the lifting mechanism is extended or retracted, the conveying surface of the first conveyor belt is higher or lower than the conveying surfaces of the third belt 320 and the fourth belt 330 .

[0128] Exemplarily, the conveying device is on the first frame 210, the first frame 210 is arranged above the second frame 220 and is slidably connected to the second frame 220, and the lifting mechanism drives the conveyor belt to move up and down.

[0129] The lifting mechanism includes: a sliding sleeve 231 and a first cylinder 232;

[0133] This utility model utilizes a jacking conveyor assembly, equipped with a jacking mechanism and a conveyor belt. By lifting the conveyor belt, it can receive servers from the assembly line. Once the servers are received, the jacking mechanism lowers the conveyor belt carrying the servers, facilitating their transfer. Furthermore, a motorized roller 250 is provided, creating a gap between the conveyor belt and the assembly line to accommodate other equipment while also allowing servers to be loaded from the assembly line. The jacking conveyor assembly improves the efficiency of transferring servers from the assembly line and reduces labor consumption.

[0134] The conveying device also has a first conveyor belt and a second conveyor belt arranged horizontally and perpendicularly to it. The second conveyor belt is two belts running parallel to each other and perpendicular to the first conveyor belt. When the first conveyor belt is lifted up, it is higher than the second conveyor belt and is used to receive servers from the assembly line. When the first conveyor belt falls, it is lower than the second conveyor belt and is used to transfer servers from the assembly line to the second conveyor belt. Driven by the second conveyor belt, the server is transferred to the test equipment located on one side of the assembly line.

[0135] This conveyor system can receive servers from the production line when the first conveyor belt of the lifting conveyor assembly is raised. When the first conveyor belt is lowered, the servers are placed on the second conveyor belt and transported to the testing equipment via the second conveyor belt. When the test is complete, the servers on the testing equipment are transferred to the second conveyor belt, and then the first conveyor belt is lifted and transported to the rear of the production line via the first conveyor belt.

The plurality of first supporting rollers 248 are arranged in a linear array between the first active roller 242 and the first tensioning roller 244 and between the first active roller 242 and the second tensioning roller 246 .

[0146] In some embodiments, the surfaces of the first support rollers 248 are covered with elastic material.

[0147] Exemplarily, in terms of the implementation of the first conveyor belt, the implementation of the utility model is two synchronously rotating belts, the two belts are arranged at intervals, and are respectively mounted on the first end of the first active roller 242 and the first tensioning roller 244 and the second end of the first active roller 242 and the second tensioning roller 246, and a panel 247 is provided between the two belts for bearing part of the gravity.

[0148] This embodiment of the utility model conveys the server via two belts spaced apart, ensuring the server's correct posture. A panel 247 is provided between the two belts.
