The product flow direction of the circuit substrate in the blanking mechanism 12 is as follows: a blanking drive assembly 121 to a blanking screw guide rail assembly 122 to a blanking box 123 to a conveyor assembly 124.
As shown in fig. 1 and 4, the blanking screw guide rail assembly 122 includes a blanking box screw module 1221 and a blanking box guide rail module 1222; the base of the blanking box screw rod module 1221 is fixed on the workbench, and the movable nut of the blanking box screw rod module 1221 is connected with the blanking box 123; the blanking box guide rail module 1222 is connected with the outer end face of the blanking box 123; the blanking box guide rail module 1222 comprises a blanking box guide rail 12221 and a blanking box slider 12222; the blanking box guide rail 12221 is fixed on the end face of the outer side of the blanking box 123, and the blanking box sliding block 12222 is connected with the workbench; the blanking driving component 121 comprises a blanking driving motor 1211 and a blanking driving speed reducer 1212; the output end of the blanking drive motor 1211 is connected with the input end of a blanking drive reducer 1212; the blanking driving speed reducer 1212 is fixed on the workbench, and the output end of the blanking driving speed reducer 1212 is connected with the blanking box screw rod module 1221.
The blanking mechanism 12 is in the working process: 1) the material storage pushing assembly 112 pushes the circuit substrates into the blanking box grooves 1232 of the blanking box 123; 2) the blanking driving motor 1211 sequentially drives the blanking driving reducer 1212 and the blanking box 123 connected with the blanking driving reducer to move downwards along the blanking box guide rail 12221; 3) the blanking box 123 moves downwards to drive the circuit substrate embedded in the blanking box groove 1232 to move downwards, and the circuit substrate at the lowest end is contacted with the conveyor belt assembly 124; 4) the conveyor belt assembly 124 drives the circuit substrate contacting with it to move forward, and the blanking driving motor 1211 continues to drive the circuit substrate above to move downward to the position contacting with the conveyor belt assembly 124, so as to complete the blanking process of the circuit substrate.
The blanking mechanism 12 solves the problem that when the circuit substrate is blanked, a sucker mechanism reaches the position of the circuit substrate firstly, the circuit substrate is sucked by a sucker, then the moving mechanism acts to drive the sucker mechanism to reach the blanking position, and the sucker mechanism loosens the circuit substrate to complete the blanking of the circuit substrate; the whole blanking process needs a plurality of steps of moving the mechanism back and forth, sucking and loosening by the sucking disc mechanism and the like, so that the complexity of the blanking step of the circuit substrate is increased; and the sucking disc mechanism and the moving mechanism can only suck and move one circuit substrate in one blanking process, thereby increasing the moving time of the circuit substrate in each blanking and reducing the blanking efficiency of the circuit substrate.
