It is the basic material of PCB and is often called substrate or core board. According to the number of layers covered with copper foil, it can be divided into single-sided copper clad laminate, double-sided copper clad laminate and multi-layer copper clad laminate.

[0003] The Chinese patent authorization announcement number is CN217142573U, and the name is a device for removing edge material for copper clad laminate production, which includes a platform, a cutting knife, a hopper, a feeding assembly, a positioning block and two clamping assemblies. The feeding assembly, the clamping assembly and the positioning block are provided to achieve the advantages of automatic feeding and high cutting quality of the device;

[0004] The shortcomings of the above-mentioned prior art solution are: although the above-mentioned solution can automatically load and cut, there will be many burrs at the cut part after the copper clad laminate is cut. In order to ensure the normal progress of the subsequent processing technology, additional grinding equipment is required to grind the burrs, which undoubtedly increases the operating burden and production cost of the staff and reduces the production efficiency.

An adjusting groove 9 is provided on the bottom wall of the support frame 8, and two sets of symmetrical limit seats 10 are slidably connected inside the adjusting groove 9. The inner walls on both sides of the support frame 8 are rotatably connected with screw rods 11, and the screw rods 11 and the limit seats 10 are movably connected through threads.

A saw blade is connected to the output end of the cutting motor 13, and a fine-tuning motor 14 for driving the screw rod 11 to rotate is arranged on one side of the support frame 8. When the fixed table 4 carries the copper clad laminate for transportation, the fine-tuning motor 14 drives the limit seat 10 to move toward each other through the screw rod 11, thereby changing the cutting width of the cutting motor 13. The lifting of the cutting motor 13 is controlled by the lifting frame 12, so that copper clad laminates of different thicknesses can be cut.

[0022] The top of the processing seat 1 is slidably provided with two groups of symmetrical L-shaped bases 19, and the side of the L-shaped bases 19 close to each other is connected with several groups of telescopic rods 20 distributed at intervals, one end of the telescopic rod 20 is connected with a grinding frame 21, and a spring 22 is provided on the outside of the telescopic rod 20.
