[0021] See Figures 1-4 This utility model provides a technical solution:

[0022] A circulating conveyor system for an assembly line includes a positioning and pressing table 61, a circulating frame 130, an upper circulating conveyor assembly, a lower circulating conveyor assembly, a downward conveyor assembly, and an upward conveyor assembly. The upward conveyor assembly is disposed on one end of the circulating frame 130, and the downward conveyor assembly is disposed on the other end of the circulating frame 130. The upper circulating conveyor assembly is fixedly disposed on the top of the circulating frame 130 and its two ends cooperate with the downward conveyor assembly and the upward conveyor assembly, respectively. The lower circulating conveyor assembly is fixedly disposed on the lower part of the circulating frame 130 and its two ends cooperate with the downward conveyor assembly and the upward conveyor assembly, respectively. The upper circulating conveyor assembly, the lower circulating conveyor assembly, the downward conveyor assembly, and the upward conveyor assembly all cooperate with the positioning and pressing table 61.

The lower and upper circulation conveyor assemblies are fixed on the circulation frame 130. The upper, lower, lower, and upper circulation conveyor assemblies are all electrically connected to the technical control center on the production line. Under the control of the control center, the positioning pressing table 61 carries the machine box from the input end to the output end of the upper circulation conveyor assembly. Then, the assembled machine box is removed. At this time, the positioning pressing table 61 enters the upper end of the lower circulation conveyor assembly. Under the action of the lower circulation conveyor assembly, the positioning pressing table 61 is transported to the lower end of the lower circulation conveyor assembly and then enters the lower circulation conveyor assembly. It is then transported to the lower end of the upper circulation conveyor assembly through the lower circulation conveyor assembly. Under the action of the upper circulation conveyor assembly, the positioning pressing table 61 is lifted to the input end of the upper circulation conveyor assembly, and the machine box can be placed on it again for production.

[0023] In some embodiments, both the upper and lower circulating conveying components include a circulating drive motor 131, a circulating fixing plate 132, a transmission chain groove 133, a main sprocket 134, a secondary sprocket 135, and a transmission chain component.

The middle part of the transmission chain component is disposed in the transmission chain groove 133, and the two sides of the transmission chain component are respectively disposed on the main sprocket 134 and the secondary sprocket 135. The main sprocket 134 and the secondary sprocket 135 are rotatably disposed on the circulating fixing plate 132. The circulating drive motor 131 is fixedly disposed on the circulating frame 130 and is used to drive the main sprocket 134 to rotate.

Adjacent chain links 140 are hinged together by the transmission chain shaft 139. In this design, both ends of the drive chain shaft 139 are connected by chain links 140. The intermediate wheel 141 on the drive chain shaft 139 supports the positioning pressing table 61. The drive chain shaft 139 cooperates with the circular arc groove 138 to prevent relative slippage of the drive chain components during transmission. Two toothed plates 137 are provided on the cylindrical wheel 136, which facilitates the placement of the intermediate wheel 141 between the two toothed plates 137, resulting in smoother transmission. The specific structure is as follows: Figure 4 As shown in the figure, the secondary sprocket is separated from the drive chain components, making it easy to see the structure intuitively.

[0025] In some embodiments, both the downlink conveying assembly and the uplink conveying assembly include a circulating conveyor frame 142, a lifting component 143, and a horizontal conveying component.
