An automatic grinding machine for PCB board surface

technical field

The utility model relates to the field of PCB board processing, in particular to an automatic grinding machine for PCB board surface.

Background technique

During the processing of printed circuit boards, it is necessary to drill holes in the PCB board. After the PCB board is drilled, due to various factors such as the drilling parameters and the life of the drill tip, various holes on the PCB board will appear different degrees of edging. When the edge is produced, it needs to be polished with sandpaper. During the grinding, dust will fall on the board or in the hole. If the follow-up treatment is not good, it will cause quality problems or scrap of the product. At present, most of them use pneumatic and manual grinding. With this method, employees often neglect and omit when operating. When such problems occur, there are no effective protection measures, and the process will run normally, resulting in the quality of the PCB board after drilling. , and the current degree of automation is low, the efficiency is low, and the demand for workers is large.

The grinding machine has a simple structure and can work continuously, and can effectively remove the residual dust after grinding. There is no need to remove dust again, and the degree of automation is high.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described, wherein:

Fig. 1 is a schematic structural view of an embodiment of the utility model.

detailed description

Referring to Fig. 1, a kind of PCB board surface automatic grinding machine of the present utility model comprises frame 1, motor 2 and the speed change wheel group 3 that is connected with motor 2, and described motor 2 is installed in frame 1 bottom, and described speed change wheel Group 3 is installed on the top of the frame 1, and the motor 3 drives the variable speed wheel group 3 to rotate through the belt. The variable wheel group 3 can provide multiple rotation speeds, and can provide different rotation speeds according to PCB boards of different thicknesses; the frame 1 Both the feed end and the discharge end are equipped with drive rollers 4, and a feed belt 5 is set between the drive rollers 4. When the PCB board to be polished is placed on the feed belt 5 at the feed end, the PCB board to be polished automatically passes through the feeding The belt 5 is conveyed to the grinding area, where it is then ground. Described frame 1 is positioned at feeding belt 5 top and is provided with and is used for grinding the emery wheel 6 of PCB board drape, and described emery wheel 6 is connected with speed-changing wheel group 3 by belt, and described frame 1 is all movable installations on emery wheel 6 both sides. Pressing the pressure roller 7 of the PCB board, the frame 1 is equipped with a pressure plate 11 for preventing the PCB board from grinding and jumping, and one end of the pressure plate 11 is hinged on the frame 1 .

The frame 1 is positioned at the top of the emery wheel 6 and is provided with a dust suction device. The dust suction device is provided with a dust collection cover 9. The dust collection cover 9 also plays a protective role in addition to preventing dust from spreading. The dust collection cover 9 passes through the Exhaust pipe 10 is connected with exhaust system, and described exhaust pipe 10 is provided with exhaust fan, produces dust during grinding, and dust can drop on PCB board, and dust is sucked up by exhaust fan and enters exhaust system, when to be polished After the PCB board enters the grinding area, one end of the PCB board is firstly pressed on the feeding belt 5 by the pressure roller 7, and the PCB board continues to move forward, and then the PCB board is polished by the grinding wheel 6 to remove the edges of various holes, the pressure plate 11 Prevent the PCB board from jumping when it is polished, and at the same time, the dust suction device will wash away the dust to prevent the dust from falling on the PCB board. If the follow-up treatment is not good, it will cause product quality problems or scrap. The discharge end of the frame 1 is provided with a guide wheel set 8. After the PCB board is polished, it is sent out of the grinder through the guide wheel set 8 at the discharge end to complete the grinding.

The above is only a preferred embodiment of the utility model, but the utility model is not limited to the above-mentioned embodiment, as long as it achieves the technical effect of the utility model by any same or similar means, it should belong to the protection of the utility model scope.
