Technical Field
[0001] This utility model relates to the field of printed circuit board processing technology, specifically to a grinding device for raw material sheets of printed circuit boards. Background Technology
[0002] In the process of processing printed circuit boards (PCBs), edge grinding equipment is required to grind the edges of the PCB raw materials. However, existing edge grinding equipment can only grind one side of the PCB raw material at a time, resulting in low edge grinding efficiency and inconvenience in adapting to PCB raw materials of different sizes, thus limiting its applicability.
[0003] To address the aforementioned issues, a grinding device for printed circuit board raw material is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a grinding device for printed circuit board raw material to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for raw materials of printed circuit boards, comprising a conveyor roller, with fixing strips fixedly arranged on both sides of the top of the conveyor roller, and a mounting plate fixedly arranged in the middle of the top of one of the fixing strips. Two cylinders are fixedly installed on one side of the mounting plate, and mounting seats are fixedly arranged on one side between the two cylinders and at the top of the other fixing strip. Several fixing seats are fixedly arranged on the top of the inner side of the two mounting seats, and motors are fixedly installed inside the several fixing seats. The output ends of the several motors extend to the outside and are fixedly connected to connecting seats. Connecting blocks are engaged inside the several connecting seats, and grinding wheels are fixedly connected to the bottom ends of the several connecting blocks. Waste collection boxes are fixedly arranged in the middle of the outer side of the two mounting seats.
[0006] This edge-grinding device conveys printed circuit board raw material through a conveyor roller conveyor. Edge-grinding structures are installed on both sides of the conveyor roller conveyor, which can simultaneously grind both sides of the material, thereby improving work efficiency. During use, two cylinders push one of the mounting seats to move left and right, thereby adjusting the distance between the two mounting seats and thus the distance between the two sets of edge-grinding wheels. It can adapt to printed circuit board raw material of different sizes, making it more widely applicable.
[0007] Preferably, a fan is fixedly installed on one side of the inner wall of each of the two mounting bases, and an air outlet pipe is fixedly connected to the air inlet end of each of the two fans. The end of each of the two air outlet pipes away from the fan extends into the interior of each of the two waste collection boxes and is fixedly connected to a filter. A filter screen is fixedly installed in the middle of the inner side of each waste collection box. The combination of the filter and the filter screen facilitates the filtration of the gas entering the fan.
[0008] Preferably, the two waste collection boxes are fixedly connected to the two mounting bases at their respective connection points with air inlet pipes. The ends of the two air inlet pipes away from the waste collection boxes extend into the interior of the two mounting bases and are fixedly connected to conduits. Several dust collection hoods are fixedly connected to the surfaces of the two conduits. Two fans respectively draw air out of the two waste collection boxes, creating negative pressure inside the two waste collection boxes. This negative pressure then creates negative pressure inside the two air inlet pipes and the two conduits. The dust collected by the several dust collection hoods absorbs the debris and dust generated during edge grinding, preventing the debris and dust from flying and polluting the environment.
[0009] Preferably, the bottom ends of the two waste collection boxes are fixedly connected to discharge pipes, and valves are fixedly installed at the connection points of the two discharge pipes with the two waste collection boxes, so that the waste in the waste collection boxes can be easily discharged through the two discharge pipes.
[0010] Preferably, one side of each of the connecting seats is provided with a fixing bolt, and one side of each of the connecting blocks is provided with a threaded hole. The fixing bolts are respectively threadedly connected to the threaded holes. By loosening the fixing bolts, they are separated from the threaded holes, and the connecting blocks are no longer limited, thus facilitating the disassembly and maintenance of the grinding wheel.
[0011] Preferably, guide seats are fixedly provided on both sides of the top end of one of the fixed strips, and guide rods are slidably provided in the middle of the two guide seats. The two guide rods are fixedly connected to one of the mounting seats. The cooperation between the two guide seats and the two guide rods facilitates the stable movement of one of the mounting seats.
[0012] Preferably, anti-slip supports are fixedly installed at the four corners of the bottom of the conveyor roller conveyor, and the installation of the four anti-slip supports can play a protective role.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This edge grinding device conveys printed circuit board raw material through a conveyor roller conveyor, and edge grinding structures are set on both sides of the conveyor roller conveyor, which can simultaneously grind both sides of the material, thereby improving work efficiency. During use, two cylinders push one of the mounting seats to move left and right, thereby adjusting the distance between the two mounting seats, and thus adjusting the distance between the two sets of edge grinding wheels. It can adapt to printed circuit board raw material of different sizes and has a wider range of applications.
[0015] 2. Two fans extract air from the two waste collection boxes, creating negative pressure inside them. This negative pressure then extends to the two air inlet pipes and the two ducts. Several dust collection hoods absorb the debris and dust generated during edge grinding, preventing them from flying around and polluting the environment. Attached Figure Description

It can grind both sides of the material at the same time, thereby improving work efficiency. During use, the two cylinders 10 push one of the mounting seats 3 to move left and right, thereby adjusting the distance between the two mounting seats 3, and thus adjusting the distance between the two sets of grinding wheels 8. It can adapt to printed circuit board raw materials of different sizes and has a wider range of applications.
[0023] A fan 5 is fixedly installed on one side of the inner wall of each of the two mounting bases 3. The air inlet end of each of the two fans 5 is fixedly connected to an air outlet pipe 17. The end of each of the two air outlet pipes 17 away from the fan 5 extends into the interior of each of the two waste collection boxes 4 and is fixedly connected to a filter 18. A filter screen 11 is fixedly installed in the middle of the inner side of the waste collection box 4. An air inlet pipe 14 is fixedly connected to the connection point between each of the two waste collection boxes 4 and the two mounting bases 3. The end of each of the two air inlet pipes 14 away from the waste collection box 4 extends into the interior of each of the two mounting bases 3 and is fixedly connected to a conduit 15.

[0024] In use, the combination of filter 18 and filter screen 11 facilitates the filtration of the gas entering the blower 5.

During use, two cylinders 10 push one of the mounting seats 3 to move left and right, thereby adjusting the distance between the two mounting seats 3, and thus adjusting the distance between the two sets of edge-grinding wheels 8, which can adapt to printed circuit board raw materials of different sizes and has a wider range of applications. Several motors 7 drive several edge-grinding wheels 8 to rotate, which facilitates edge-grinding of both sides of the printed circuit board raw material. During the edge-grinding process, two fans 5 respectively extract the air from the two waste collection boxes 4, so that the two waste collection boxes 4 generate negative pressure, which in turn generates negative pressure in the two air inlet pipes 14 and the two conduits 15. The debris and dust generated by edge-grinding are absorbed by several dust collection hoods 16, preventing debris and dust from flying and causing environmental pollution.
