The connecting section 34 is used for connecting the driving block 32 and the driven block 33 (the connecting section 34 is an aluminum section). The driving shaft 35 is rotatably inserted into the driving block 32 (bearings can be installed in the through holes of the driving block 32, and both ends of the driving shaft 35 are respectively installed in the bearings). The driving wheel 37 is sleeved on the driving shaft 35 and is positioned on one side of the driving wheel block 32 opposite to the driving wheel (the driving wheel 37 is fixed with the driving shaft 35 through a flat key). The driven shaft 36 is movably disposed through the driven block 33 (the driven shaft 36 is movable within a rounded rectangular slot in the driven block 33). The driven wheel 38 is sleeved on the driven shaft 36 and is positioned on one side opposite to the driven wheel block 33 (the driven wheel 38 is arranged on the driven shaft 36 through a bearing). The belt 39 is wound around the driving wheel 37 and the driven wheel 38 (the belt 39 is made of a common rubber material, which has a light weight and is stably driven, the belt 39 is wound around the driving wheel 37 and the driven wheel 38, and the driven wheel 38 is moved to tighten the belt 39). The rotation of the belt 39 is effected by means of a second drive means (the second drive means being a servo motor 40, it being sufficient to connect the motor shaft of the servo motor 40 to either end of the drive shaft 35). In this embodiment, the servo motor 40 rotates the driving shaft 35, the driving wheel 37 is fixedly connected with the driving shaft 35 through a flat key, so that the driving wheel 37 rotates synchronously with the driving shaft 35 and rotates the belt 39 synchronously, the driven shaft 36 can move on the driven wheel block 33 to ensure the tension degree of the belt 39, and the driven wheel 38 is connected with the driven shaft 36 through a bearing, so that the belt 39 drives the driven wheel 38 to rotate synchronously, but the driven shaft 36 does not rotate.

Further, two gussets 41 are provided, which are fixed to the connecting section 34 (the gussets 41 are made of black POM plastic material and limit the position of the trays that are conveyed onto the belt 39). The chain 42 is fixed to the platen 11 along the sliding direction of the base plate 31 (the chain 42 is used for placing wires and the like, on one hand, preventing the wires from being stacked disorderly and generating local overheating to cause short circuit, and on the other hand, for aesthetic reasons). A proximity switch 45 is fixed on the bottom plate 31 on the side close to the driving block 32 (the proximity switch 45 is used for accurately positioning the tray transported by the belt 39). A support plate 46 is fixed on the opposite side of connecting section 34 between driving wheel 37 and driven wheel 38 (support plate 46 is used for supporting the tray supported by belt 39, and prevents the deformation of belt 39 caused by pressing belt 39 down by the tray).

When the automatic feeding and recycling tray structure is actually used, a tray filled with materials is placed on the conveying belt 23 of one group of the conveying assemblies 2 and is driven by the speed reducing motor 25 to move to the positioning assembly 3; the servo motor 40 drives the belt 39 to rotate (the servo motor 40 drives the driving shaft 35 to rotate, the driving wheel 37 is fixedly connected with the driving shaft 35 through a flat key, so that the driving wheel 37 rotates synchronously with the driving shaft 35 to drive the belt 39 to rotate synchronously, the driven shaft 36 can move on the driven wheel block 33 to ensure the tensioning degree of the belt 39, and the driven wheel 38 is connected with the driven shaft 36 through a bearing, so that the belt 39 drives the driven wheel 38 to rotate synchronously, but the driven shaft 36 does not rotate). The tray is transferred to the belt 39 by the conveyor belt 23, the tray moves slowly on the belt 39, the position of the tray can be monitored in time through the proximity switch 45, and when the tray is close to the proximity switch 45, the proximity switch 45 controls the servo motor 40 to stop rotating (the distance between the tray and the proximity switch 45 can be regulated); then the cylinder drives the positioning component 3 to slide on the bedplate 11 to a manipulator grabbing position, the manipulator clamps away the product on the tray, then the servo motor 40 rotates reversely, the empty tray moves reversely to another group of transportation components 2 to place the product to be processed, then the cylinder drives the positioning component 3 to reset, and the steps are repeated.
