Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1 , the embodiment of the present invention includes:

[0026] A belt-type circular jig conveying mechanism comprises: a product jig 1, a first assembly line 2, a second assembly line 3, a material pushing mechanism 4, and a lifting mechanism 5.

[0027] The product fixture is arranged on the first assembly line and the second assembly line, the first assembly line and the second assembly line are arranged in parallel, the pushing mechanism is arranged at the ends of the first assembly line and the second assembly line, and connects the first assembly line and the second assembly line, and the lifting mechanism is arranged on the first assembly line and the second assembly line.

[0028] Among them, there are two pushing mechanisms, one pushing mechanism connects the unloading end of the first assembly line and the loading end of the second assembly line, and the other pushing mechanism connects the unloading end of the second assembly line and the loading end of the first assembly line, so that the overall structure presents a "U" shape, realizing the circulation of product jigs. When using the product jigs, only the jigs need to be moved, and other mechanisms and equipment do not move, so that the stability of the equipment is improved, and multiple jigs flow on the assembly line at the same time, driving different mechanisms to work at the same time, thereby improving work efficiency.

[0029] The product jig can move forward from the first assembly line to the pushing mechanism, which moves the product jig from the first assembly line to the second assembly line. The second assembly line first drives the product jig to the lifting station to facilitate other stations to process the products, and then continues to transport the product jig. The pushing mechanism moves the product jig on the second assembly line to the first assembly line.

[0030] The first assembly line and the second assembly line have the same mechanism, but different running directions. The assembly line structure includes a frame 21, a baffle 22, a transmission wheel 23, a tension wheel 24, a conveyor belt 25, a synchronous wheel 26, a rotating shaft 27, a synchronous belt (or belt) 28, a motor 29, and a mounting frame 30.

[0031] The baffle is arranged on both sides of the frame, the mounting frame is connected to the baffle or the frame, the motor and the rotating shaft are arranged on the mounting frame, the output shaft of the motor and the rotating shaft are provided with synchronous wheels, a synchronous belt is wound around the synchronous wheel, the transmission wheel is rotatably arranged on the rotating shaft and the baffle, the tensioning wheel is rotatably arranged on the baffle and the mounting frame, the conveyor belt is wrapped around the transmission wheel and the tensioning wheel, the motor drives the rotating shaft to rotate on the mounting frame through the synchronous wheel and the synchronous belt, and the rotating shaft drives the conveyor belt to operate on the frame, thereby driving the product fixture to move.

[0032] Among them, two baffles are relatively arranged on the frame, and a conveyor belt is arranged on the inner wall of each baffle to facilitate the smooth and rapid transmission of product jigs. In addition, the assembly line for jig movement adopts belt and synchronous wheel transmission, so that the noise during the movement of the mechanism can be effectively reduced during the movement of the jig.

[0038] When the sensor detects that the jig is in place, the supporting cylinders at the upper and lower material positions drive the supporting plates to rise through the cylinder connecting blocks (the guide shaft guides when it moves up and down), so that the supporting plates pass through the gaps between the conveyor belts and move to the top of the conveyor belts; the supporting plate at the upper material position lifts up the product jig, so that the product jig is separated from the conveyor belt at the upper material position; the horizontal cylinder drives the push plate to translate through the connecting plate, and the push plate and the push block drive the product jig to pass through the translation plate and move to the supporting plate at the lower material position; the supporting cylinder at the lower material position drives the supporting plate to descend, so that the product jig is placed on the conveyor belt at the lower material position; the supporting plate continues to descend and separates from the product jig to achieve the reflux of the jig.
