One end of the conveying guide rail 800 is communicated with the vibrating tray, the other end of the conveying guide rail extends to the upper side of the material receiving part, and metal components in the vibrating tray orderly fall into the material storage device through the conveying guide rail 800. The driving parts are arranged at two sides of the conveying guide rail 800, and rotate to stir the metal components on the conveying guide rail 800, so that the metal components orderly fall into the accumulator, and finally, the feeding manipulator takes away the metal components in the accumulator to finish the feeding operation.
Specifically, the two conveying guide rails 800 are arranged in parallel, and according to the actual production situation, the conveying guide rails 800 can be arranged in parallel in multiple rows, so that the production efficiency is improved. One end of the conveying guide rail 800 is communicated with the vibrating tray, and the other end horizontally or obliquely extends downwards to above the material receiving part, so that the metal components orderly fall into the material storage device from the vibrating tray through the conveying guide rail 800.
Specifically, the driving parts are correspondingly arranged in two groups and are positioned at the outer side of the conveying guide rail 800, the number of the driving parts corresponds to that of the conveying guide rail 800, and when the conveying guide rail 800 is increased, the driving parts are correspondingly increased. The driving part mainly includes a first stepping motor 821, a first coupling 822, a toothed disc 823, and a blanking sleeve 824 for dropping a metal member into a stocker 831 in a vertical direction.

The two sets of position sensors 825 are respectively arranged at two sides of the material storage 831 and positioned under the blanking sleeve 824, and the detection ports of the position sensors face the material storage 831. When the fluted disc 823 is used for pulling the metal component to fall into the material storage 831 correctly, the detection signal sent by the position sensor 825 is blocked, so that the current falling of the metal component into place can be judged and the next row of blanking operation is prepared, when the metal component falls out of the material storage hole, the signal sent by the position sensor 825 is not blocked, and the control system can recognize that the metal component does not fall into place and needs manual intervention.
In order to improve the blanking efficiency of the blanking device, the blanking device 831 of the present invention is provided with two rows of storage holes, wherein the number of each row of storage holes is 7, and the depth of each storage hole is two thirds of the length of the metal member. In actual production, the number of storage holes and the number of rows of the storage device 831 can be determined according to the single injection molding amount of the injection molding machine, so that the feeding efficiency can be better improved, and the production period can be shortened.
