Description

A kind of chip removal plate

Technical field

The utility model relates to PCB processing more particularly to a kind of chip removal plates.

Background technique

With the densification of printed circuit board, the number of plies of plate is more and more, hole aspect ratio is increasing, drilling process The unsmooth phenomenon of chip removal it is more serious, traditional common wood-pulp board chip space is easily deformed, cannot be repeated as many times and use, and chip space Bottom is obstructed, is unfavorable for siphoning away break flour, and the having some setbacks of chip removal can make drilling process chip to the severe crush of drill point and hole wall, from And the problems such as drill point deflection and poor hole wall quality occurs.

Utility model content

The purpose of the utility model is to provide a kind of chip removal plates.

To achieve the goals above, the technical solution of the utility model is:

A kind of chip removal plate, which is characterized in that it includes plate body, and the plate body includes several workspaces, and the workspace is in The distribution of rectangular array shape, four angles of each workspace are respectively equipped with a positioning hole, and the location hole is arranged through plate body, described The lower surface of plate body is equipped with several chip spaces, and the chip space is parallel and spaced set, one end of the chip space are closed There are spacing, the other end of the chip space extends to the other end of plate body, the row for one end of end, the sealed end and plate body The other end for considering slot to be worth doing is open end, and the width of chip space covering workspace setting, the chip space is extremely open by sealed end End is gradually increased, and the inner wall of the chip space two sides is equipped with a pair of of raised line to center protrusion, and the raised line is located in chip space Portion.

Utility model has the advantages that chip removal plate lower surface is arranged chip space, the width of chip space is by sealed end to opening Mouthful end is gradually increased, and clast and rubbish are easy to be discharged from open end when cleaning；The middle part of location hole ring-shaped depression outward, is fixed Position hole and positioning column leave certain space, location hole not easy damaged；Raised line is equipped in the middle part of chip space, when clast is dropped out from chip space Compared with concentration, will not dissipate.

Specific embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical Novel protected range.

The utility model discloses a kind of chip removal plates, which is characterized in that as shown in Figure 1, it includes plate body 1, the plate body 1 Including several workspaces 2,2 rectangular array shape of the workspace distribution, four angles of each workspace 2 are respectively equipped with a positioning Hole 3, the location hole 3 are arranged through plate body 1, and as shown in Figures 2 and 3, the lower surface of the plate body 1 is equipped with several chip spaces 5, the chip space 5 is parallel and spaced set, one end of the chip space 5 are sealed end 501, the sealed end 501 and plate For the outer rim of 1 one end of body there are spacing, the other end of the chip space 5 is open end 502, and the other end of the chip space 5 extends To the outer rim of 1 other end of plate body, the chip space 5 covers workspace 2 and is arranged, right before the fluting of the positive workspace 2 of plate body 1 Chip space 5 is first cleaned, and the width of the chip space 5 is gradually increased by sealed end 501 to open end 502, cleaning equipment folder When firmly sealed end 501 is cleaned, the clast and rubbish of chip space 5 are easy to be discharged from open end 502.

As shown in figure 4, the inner wall of the location hole 3 is equipped with annular recess 4, other positioning workpiece such as positioning columns penetrate positioning Behind hole 3, annular recess 4 reduces the contact area of location hole 3 Yu positioning column, has reserved certain space, so that location hole 3 and fixed The not easy damaged of location hole 3 when the column contact of position, when it is implemented, the location hole 3 can also be in 1 front of plate body, back side both ends aperture It is small, the big structure of plate body median pore radius.

As depicted in figs. 1 and 2, when it is implemented, the pad of plate body 1 is under pcb board, the front of plate body 1 divides altogether three rows two Totally six workspaces 2 are arranged, in 2 internal recessing of workspace, the slot and chip space 5 that milling cutter opens up are drilled with milling cutter in tow sides connection The front of plate body 1 is blown with blower after the completion, the clast in plate body 1 drops out under acting in wind from the open end of chip space 5 501, As shown in figure 5, the middle part of chip space 5 is equipped in a pair of thin and narrow raised line 6(Fig. 2, raised line is tiny, is not drawn into) so that clast from Chip space 5 is more concentrated when dropping out, and will not be dissipated everywhere.

Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new The range of each embodiment technical solution of type.
