[0018] The beneficial effects of the present invention are:

[0019] 1. The cutting component is movably connected to one end of the carrier component, so that the cutting component can be slidably connected to different positions of the end of the carrier component to meet the needs of cutting the copper clad laminate into different sizes. When the cutting component falls and rolls with the carrier component, the copper clad laminate moving on the carrier component contacts the cutting component, which is used for synchronous cutting of the copper clad laminate during the transfer process. By using several sets of tool mechanisms to be clamped on the adjustment mark rod, the cutting width of the copper clad laminate can be freely adjusted, which is suitable for batch cutting and achieves efficient cutting effect.

[0020] 2. The output end of the first cylinder drives the air deflector to fall, so that the air deflector is separated from the third chute, reducing the heat loss caused by the high-temperature gas in the first chute entering the air deflector. Under the action of the electric heating wire in the air collecting pipe, the temperature of the gas is increased, and the high-temperature gas enters the first chute vertically. When the cut copper clad laminate body is unloaded from the second chute and the third chute, the copper clad laminate body is partially baked to eliminate the internal stress in the copper clad laminate, so as to reduce the deformation of the board in the subsequent processing process.

[0021] 3. The output end of the second cylinder is used to drive the adjustment marking rod to fall, and the length of the first telescopic rod and the second telescopic rod, as well as the angle adjustment of the first sliding sleeve, the second sliding sleeve, the first hinge seat and the second hinge seat are used to make the falling knife holder drive the circular blade to fall and contact with the feed roller, so that the copper clad laminate body moving on the feed roller is cut into equal-spaced segments when passing through the circular blade, thereby improving the accuracy of adjustment.

[0022] 4. The output end of the second motor drives the grinding cone rod to rotate continuously, and grinds the port of the copper clad laminate body after cutting to prevent the sharp corners and burrs of the board from scratching the printed circuit board or the operator during the processing. In addition, since the first cylinder drives the air deflector to fall, the copper clad laminate body discharged through the third chute can use the outer wall arc surface of the air deflector for buffering during the unloading process, which reduces the right-angle wear between the copper clad laminate body and the port of the third chute, and effectively protects the surface gloss of the copper clad laminate body.

[0054] The working principle of a cutting device for a high thermal conductivity copper-clad laminate proposed by an embodiment of the present invention is as follows:

[0055] A plurality of feeding rollers 131 are laid in the loading platform 11, and a vacuum pump 14 continuously works to form a negative pressure at the ports of the plurality of vacuum branch pipes 133, so as to adsorb and position the copper-clad laminate body 2 on the surface of the feeding rollers 131, and the vacuum tube 132 is driven to rotate through the output end of the first motor 15, so that the copper-clad laminate body 2 on the plurality of feeding rollers 131 moves toward one side of the feeding rollers 131;

[0056] The output end of the first cylinder 19 pushes the air guide 18 to rise and clamp it on the outer wall of the third chute 114, so that the third chute 114 and the second chute 113 are connected to each other, and the first air pump 112 is used to continuously inject gas into the air collecting pipe 110, and under the action of the electric heating wire in the air collecting pipe 110, the temperature of the gas is increased, so that the high-temperature gas is accumulated in the first chute 17, and the high-temperature gas in the first chute 17 is blown to one side of the copper clad laminate body 2 by the U-shaped structure of the inner wall of the air guide 18, so as to reduce the impurities remaining in the copper clad laminate body 2 during cutting, and to perform preliminary surface baking on the copper clad laminate body 2 during the cutting process;

[0057] The output end of the first cylinder 19 drives the air deflector 18 to fall, so that the air deflector 18 is separated from the third chute 114, reducing the heat loss caused by the high-temperature gas in the first chute 17 entering the air deflector 18, so that the temperature of the gas is increased under the action of the electric heating wire in the air collecting pipe 110, so that the high-temperature gas enters the first chute 17 vertically, and the copper clad board body 2 is partially baked when the cut copper clad board body 2 is discharged from the second chute 113 and the third chute 114, so as to eliminate the internal stress in the copper clad board and reduce the deformation of the board in the subsequent processing process;

[0058] The output end of the second cylinder 32 is used to drive the adjustment mark rod 33 to fall, and the length of the first telescopic rod 35 and the second telescopic rod 371 is adjusted, and the angle of the first sliding sleeve 34, the second sliding sleeve 36, the first hinge seat 372 and the second hinge seat 375 is adjusted, so that the falling knife holder 376 drives the circular blade 379 to fall and contact the feeding roller 131, and the copper clad board body 2 moving on the feeding roller 131 is cut into equal-spaced segments when passing through the circular blade 379;

[0059] The high temperature resistant telescopic sheath 38 is clamped on the inner wall of the first chute 17, so that the edge grinding cone rod 374 is slidably connected to any position of the inner wall of the first chute 17, and the top of the first chute 17 can be blocked to prevent the high temperature gas from leaking out from the top of the first chute 17;

[0060] When one end of the copper clad laminate body 2 moves close to the unloading roller 12, since the copper clad laminate body 2 after cutting lacks the adsorption effect of the feeding roller 131, the cut port of the copper clad laminate body 2 can contact with the edge grinding cone rod 374, and the output end of the second motor 373 drives the edge grinding cone rod 374 to rotate continuously, and the cut port of the copper clad laminate body 2 is edged to prevent the sharp corners and burrs of the board from scratching the printed circuit board or the operator during the processing. In addition, since the first cylinder 19 drives the air guide cover 18 to fall, the copper clad laminate body 2 discharged through the third slide chute 114 can use the outer wall arc surface of the air guide cover 18 for buffering during the unloading process, thereby reducing the right-angle wear between the copper clad laminate body 2 and the port of the third slide chute 114, and effectively protecting the surface gloss of the copper clad laminate body 2.
