Abstract
The utility model relates to an automatic board unloading stripping device used for a circuit board forming machine. The automatic board unloading stripping device comprises a frame, an upper bakelite plate is fixed to the upper surface of the frame, a lower bakelite plate which can move up and down is arranged on the lower portion of the frame, a pulp board is fixed to the upper surface of the upper bakelite plate, PIN locating holes are formed in the lower bakelite plate, communicated through holes are formed in the upper bakelite plate and the pulp board, and the through holes correspond to the PIN locating holes in the lower bakelite plate one to one. The automatic board unloading stripping device is characterized in that the PIN locating holes are step holes, the hole diameter of the upper portions of the PIN locating holes is the same as the hole diameter of the through holes, and the hole diameter of the lower portions of the PIN locating holes is smaller than the hole diameter of the upper portions of the PIN locating holes. According to the automatic board unloading stripping device, the thickness of the upper bakelite plate used for stripping on the forming machine is changed, and accordingly the depth of big holes is reduced and the probability of PIN deviation when PINs are knocked is also reduced, therefore, the abnormity of fishing deviated products in the CNC machining process can be avoided, the first pass yield of an initial workpiece is improved, and the utilization rate of the machine is improved.
Description
Technical field
The utility model relates to a kind of automatic board descending stripper for circuit board forming machine, belongs to printed circuit board processing device field.
Background technology
Along with consumption electronic product is lightening, integrated, the development trend of multifunction, its quality requirements to printed circuit board (PCB) is more and more higher.Comparatively speaking, print circuit plates making cost is also more and more higher, the profit that printed circuit board (PCB) manufacture obtains is relatively more and more lower, in order to reduce the cost of manufacture of printed circuit board (PCB), in the manufacture craft process of printed circuit board (PCB), each technique progressively imports automation, by reducing manpower, the minimizing equipment upper and lower plates time, carry out the mobility of lifting means.And in print circuit plates making process, CNC(Computer numerical control wherein, Digit Control Machine Tool) processing, forming machine also imports the device of the de-material of automatic board descending.At present automatic board descending stripper has two kinds, and (1) is a kind of is the make progress stripper of top mode of PIN pin: PIN pin is located in printed circuit board (PCB) CNC processing, and use diameter is 15.8mm; (2) the second is for using the bakelite plate of 4mm thickness to be fixed on framework, by the cylinder top stripper that makes progress; And the forming machine of employing the second stripper, printed circuit board (PCB) PIN pin diameter for CNC processing location is 19.8mm, because it need to use two-layer bakelite plate, wherein one deck bakelite plate thickness is 12mm below, act as above PIN pin is planted in, fixedly PIN pin, is to be also convenient to positioning printing circuit board, be the bakelite plate of 4mm thickness above, be convenient to the de-material of lower plate.There is following defect in above-mentioned operation: (1) CNC course of processing because of boring twice, and is long PIN pin, is prone to that to strike PIN inclined to one side and cause dragging for inclined to one side quality abnormal; (2) moulding initial workpiece first-pass yield is on the low side, affects the mobility of board.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of automatic board descending stripper for circuit board forming machine is provided, and improves production quality, promotes the mobility of producing board.
The technical scheme providing according to the utility model, a kind of automatic board descending stripper for circuit board forming machine, comprises framework, bakelite plate on frame upper surface is fixing, the below of framework arranges lower bakelite plate moving up and down; Described upper bakelite plate upper surface is paper paddle board fixedly; On described lower bakelite plate, be provided with PIN pin location hole, be provided with the through hole of connection on upper bakelite plate and paper paddle board, through hole is corresponding one by one with the PIN pin location hole on lower bakelite plate; Feature is: described PIN pin location hole is stepped hole, and the aperture on PIN pin location hole top is consistent with the aperture of through hole, and the aperture on the aperture ratio top of PIN pin location hole bottom is little.
The aperture of described through hole equals the diameter of the location hole on printed circuit board or than the large 0.2～0.5mm of the diameter of the location hole on printed circuit board.
The little 0.05mm of diameter of the location hole on the aperture ratio printed circuit board of described PIN pin location hole bottom.
The thickness of described upper bakelite plate is 2mm, and the thickness of lower bakelite plate is 12mm.
The degree of depth of described PIN pin location hole is 5～6mm.
The utility model has changed the thickness of forming machine for the upper bakelite plate of de-material use, so just reduced the degree of depth of macropore, also reduced while striking PIN pin, produce the inclined to one side probability of PIN pin, just can avoid occurring dragging in the CNC course of processing the abnormal generation of inclined to one side product, promote initial workpiece first-pass yield, promoted the mobility of board.

Fig. 3 is the schematic diagram of PIN pin location hole described in the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in FIG. 1 to 3: the automatic board descending stripper of described circuit board comprises framework 1, upper bakelite plate 2, paper paddle board 3, printed circuit board 4, lower bakelite plate 5, PIN pin location hole 6, PIN pin 7, through hole 8 etc.
As shown in Figure 1 and Figure 2, the utility model comprises framework 1, bakelite plate 2 on framework 1 upper surface is fixing, and the below of framework 1 arranges lower bakelite plate 5 moving up and down; Described upper bakelite plate 2 upper surfaces are paper paddle board 3 fixedly, and the upper surface of paper paddle board 3 is used for placing printed circuit board 4; On described lower bakelite plate 5, be provided with PIN pin location hole 6, PIN pin location hole 6 location for PIN pin 7; On bakelite plate 2 and paper paddle board 3, be provided with the through hole 8 of connection on described, through hole 8 is corresponding one by one with the PIN pin location hole 6 on lower bakelite plate 5;
The thickness of described upper bakelite plate 2 is 2mm, and the thickness of lower bakelite plate 5 is 12mm; The aperture of described through hole 8 equals the diameter of the location hole on printed circuit board 4 or than the large 0.2～0.5mm of the diameter of the location hole on printed circuit board 4;
As shown in Figure 3, described PIN pin location hole 6 is stepped hole, and the aperture on PIN pin location hole 6 tops is consistent with the aperture of through hole 8, the little 0.05mm of diameter of the location hole on the aperture ratio printed circuit board 4 of PIN pin location hole 6 bottoms;
