Abstract
The utility model relates to a printed circuit, in particular to a grinder for removing burrs of a PCB (Printed Circuit Board) in the printed circuit, and provides the grinder for removing the burrs of the PCB. The grinder comprises a frame, wherein, upper grinding-brushing wheels and lower grinding-brushing wheels are arranged on the frame; the two ends of each upper grinding-brushing wheel are rotationally connected with the frame respectively; and the two ends of each lower grinding-brushing wheel are rotationally connected with the frame respectively. The grinder has the benefits that the burrs and flashes produced on the edges of holes can be ground and removed through the upper grinding-brushing wheels and the lower grinding-brushing wheels, and the quality problems that the holes are small, scratches are produced and the appearance is influenced are avoided.
Description
Technical field
The utility model relates to printed circuit, relates in particular to a kind of grinding machine of removing the printed substrate burr in the printed circuit.
Background technology
PCB(Printed Circuit Board), Chinese is a printed circuit board, claims printed circuit board (PCB), printed substrate again, is the important electron parts, is the supporter of electronic devices and components, is the supplier that electronic devices and components are electrically connected.In the production process of printed substrate, need hole to printed substrate, printed substrate after boring, the burr that can produce at the bore edges place, after electroplating, burr will cause that the hole is little, scratch, influence the quality problem of outward appearance.
Summary of the invention
In order to solve the problems of the prior art, the utility model provides a kind of grinding machine of removing the printed substrate burr.
The utility model provides a kind of grinding machine of removing the printed substrate burr, comprise support, described support is provided with polish-brush wheel and following polish-brush wheel, and described two ends of going up the polish-brush wheel are rotatably connected with described support respectively, and the described two ends of polish-brush wheel down are rotatably connected with described support respectively.
As further improvement of the utility model, described upward polish-brush wheel and the described wheel of polish-brush down are tangent.
As further improvement of the utility model, the described polish-brush wheel of going up has two.
As further improvement of the utility model, the described wheel of polish-brush down has two.
As further improvement of the utility model, the described polish-brush wheel of going up is along its bristle that extended radially outwardly.
As further improvement of the utility model, the described wheel of polish-brush down is along its bristle that extended radially outwardly.
The beneficial effects of the utility model are: by such scheme, burr, the burr that can produce by last polish-brush wheel and following polish-brush wheel worn bore edges place are avoided causing that the hole is little, scratch, are influenced the quality problem of outward appearance.
Description of drawings
Fig. 1 is a kind of structural representation of removing the grinding machine of printed substrate burr of the utility model.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
