Detailed Description

Referring to fig. 1-6, the utility model relates to a PCB board separator, which comprises a workbench 6, an upper die and a lower die 7 arranged on the workbench 6, wherein the upper die consists of a material separating cylinder 1, a board separating module 2 and a compressing part 3, a bracket 4 is arranged on the workbench 6, the material separating cylinder 1 is fixed on the bracket 4, a piston rod of the material separating cylinder 1 is connected with the board separating module 2 in a manner of penetrating through the bracket 4, a guide post 5 is also arranged on the workbench 6, the board separating module 2 and the compressing part 3 are both sleeved on the guide post 5, and the piston rod of the material separating cylinder 1 drives the board separating module 2 to push the compressing part 3 to compress a PCB board on the lower die 7 in the direction of driving the lower die 7; in addition, the guide post 5 is further sleeved with a spring (not shown in the figure), the spring is located between the lower die 7 and the pressing part 3, and when the die is removed, the spring can jack up the pressing part 3, so that the space between the pressing part 3 and the lower die 7 is opened, and the rim charge and the PCB board can be taken out together.

Specifically, the pressing part 3 extends to the periphery and can cover the occupied area of the whole continuous sheet type PCB 8, and when in punching, the pressing force can be fully transferred to each surface and edge of the PCB, so that the punching cutter 11 arranged on the separating plate module 2 can avoid the deformation of the edge of the PCB when in punching, and in addition, more contact surfaces can prevent the displacement of the PCB.

The lower die 7 is provided with a placing surface for placing the continuous sheet type PCB 8, the placing surface is provided with a plurality of waste tanks 31, the waste tanks 31 correspond to the inner rim charge 10 between the PCBs, and the inner rim charge 10 falls into the waste tanks 31 after being separated from the PCBs in the blanking process.

In this embodiment, the device further includes a discharging cylinder 15 and a discharging plate 14, the discharging plate 14 is connected with a piston rod of the discharging cylinder 15, and the discharging plate 14 is located at a side surface of the lower die 7, under the operation of the discharging cylinder 15, the discharging plate 14 can enter into a placement surface to push out the outer material 9 of the chip-connected PCB 8 and the PCB together; the two ways of discharging the inner rim charge 10 and the outer rim charge 9 on the PCB board are based on a larger difference in space occupation rate between the two rim charges, the outer rim charge 9 is continuous, a rectangular frame body is formed after being punched out, the number of the waste tanks 31 can be reduced through the cooperation of the discharging plate 14 and the discharging cylinder 15, and the waste tanks 31 for the rectangular frame body to pass through are not required to be specially arranged.
