Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

A second motor 5 is installed on the right surface of the operating table 1, and the output end of the second motor 5 slides through the right surface of the operating table 1 and extends to the inside of the sliding groove 15. A screw rod 51 is rotatably connected between the inner surface walls on both sides of the sliding groove 15, the output end of the second motor 5 is fixedly connected to the right end of the screw rod 51, and the outer surface of the screw rod 51 is threaded through the outer surface of the sliding block 52. Two first motors 4 are symmetrically embedded near the edges of both sides of the front surface of the operating table 1, and a cutting knife 41 is installed at the output end of the first motor 4. The right surface of the first limit block 12 is inclined, the second limit block 13 is trapezoidal, and the left surface of the third limit block 14 is inclined.

[0029] The effect achieved by the entire embodiment 1 is that when the device is used to cut the circuit board, the circuit board body 35 is installed on the clamping table 3, and then the first motor 4 and the second motor 5 are started. When the first motor 4 is started, the cutting knives 41 on both sides of the front of the operating table 1 will be driven to rotate at a high speed. When the second motor 5 is started, the screw rod 51 will be driven to rotate. When the screw rod 51 rotates, it will drive the sliding block 52 inside the sliding groove 15 to move from left to right. When the sliding block 52 moves, it will drive the top sliding plate 2 to move synchronously. When the sliding plate 2 is in the left position, the steering column 23 below is located on the right side of the steering shaft 26, and the steering column 23 can only move linearly between the first limit block 12 and the rectangular groove 11. When the sliding plate 2 moves to the right position where the first limit block 12 and the second limit block 13 intersect, the steering column 23 will move between the first limit block 12 and the second limit block 13, and be located to the left and rear of the steering shaft 26.

At this time, the steering seat 24 connected above the steering shaft 26 will simultaneously drive the clamping table 3 and the circuit board body 35 to rotate, so that when the circuit board body 35 is at the left side of the operating table 1, the front side surface will be neatly cut by one of the cutting knives 41, and when it moves to the right side, the rear surface of the circuit board body 35 will be neatly cut by the other cutting knife 41 after rotating to the front side. The overall structure is simple, and the cutting operation of the two surfaces of the circuit board body 35 can be quickly completed without a complex driving mechanism, with low cost and high work efficiency. The steering shaft 26 is connected to the sliding plate 2 through the bearing 21, so the friction force is small during rotation, and the slide rail 16 and the slider 53 cooperate to limit the sliding plate 2, so that it maintains a high stability when sliding left and right.

[0030] Embodiment 2, as Figure 1-Figure 6 As shown, an L-shaped frame 31 is symmetrically fixedly connected to the top of the clamping platform 3 near the edges on both sides, an electric push rod 32 is fixedly installed on the top of the L-shaped frame 31, a fixing bolt 25 is threadedly penetrated and connected to the right surface of the clamping platform 3, the telescopic end of the electric push rod 32 slides through the top of the L-shaped frame 31 and extends to the bottom, the telescopic end of the electric push rod 32 is fixedly connected to a splint 33, and a rubber pad 34 is bonded to the bottom of the splint 33.

[0031] The effect achieved by the entire embodiment 2 is that when the circuit board body 35 is installed on the top of the clamping platform 3, it is first placed on the clamping platform 3, and then the electric push rods 32 on both sides are started to drive the clamping plate 33 and the rubber pad 34 to move downward to fix it. The operation is convenient. When it is necessary to process the circuit board bodies 35 of different lengths, the fixing bolt 25 is rotated to loosen, and then the circuit board body 35 is placed on the top of the clamping platform 3 so that the clamping platform 3 is located in the middle position of the circuit board body 35, and then the clamping platform 3 is pushed back and forth to move it back and forth on the top of the steering seat 24. By this method, the cutting position of the front surface of the circuit board body 35 and the cutting knife 41 are adjusted to the corresponding positions, and then the fixing bolt 25 is advanced. After the fixing bolt 25 is tightened, the rear end face and the surface of the steering seat 24 are tightly in contact to complete the fixation of the clamping platform 3. The design structure is simple, and circuit board bodies 35 of different lengths can be processed, and it has high versatility.

[0032] Working principle: When using the device to cut the circuit board, place the circuit board body 35 on the clamping table 3, then start the electric push rods 32 on both sides to drive the clamping plate 33 and the rubber pad 34 to move downward to fix them, and then start the first motor 4 and the second motor 5. When the first motor 4 is started, it will drive the cutting knives 41 on both sides in front of the operating table 1 to rotate at high speed. When the second motor 5 is started, it will drive the screw rod 51 to rotate. When the screw rod 51 rotates, it will drive the sliding block 52 inside the sliding groove 15 to move from left to right. When the sliding block 52 moves, it will drive the top sliding plate 2 to move synchronously. When the sliding plate 2 is in the left position, the steering wheel below The column 23 is located on the right side of the steering shaft 26, and the steering column 23 can only move in a straight line between the first limit block 12 and the rectangular groove 11. When the sliding plate 2 moves to the right position where the first limit block 12 and the second limit block 13 intersect, the steering column 23 will move between the first limit block 12 and the second limit block 13 and be located to the left rear of the steering shaft 26. When the sliding plate 2 moves to the middle position of the operating table 1, the steering column 23 is located directly behind the steering shaft 26. When the sliding plate 2 moves to the right side, the steering column 23 will be dragged by the connecting block 22 and slide to the left side of the steering shaft 26 after passing the second limit block 13 and the third limit block 14. During the whole process, the steering column 23 will move from the right side of the steering shaft 26 to the left side, and at the same time, the steering shaft 26 will be pulled by the connecting block 22 to rotate 180 degrees. At this time, the steering seat 24 connected to the upper part of the steering shaft 26 will simultaneously drive the clamping table 3 and the circuit board body 35 to rotate, so that when the circuit board body 35 is at the left side of the operating table 1, the front side surface will be neatly cut by one of the cutting knives 41, and when it moves to the right side, the rear surface of the circuit board body 35 will be rotated to the front side and neatly cut by the other cutting knife 41. The overall structure is simple, and the cutting operation of the two sides of the circuit board body 35 can be quickly completed without a complex driving mechanism, so the cost is low and the work is simple. The working efficiency is high. When it is necessary to process the circuit board body 35 of different lengths, rotate to loosen the fixing bolt 25, and then place the circuit board body 35 on the top of the clamping table 3 and make the clamping table 3 located in the middle position of the circuit board body 35. Then push the clamping table 3 back and forth to move it back and forth on the top of the steering seat 24. After the cutting position of the front surface of the circuit board body 35 and the cutting knife 41 are adjusted to the corresponding positions by this method, the fixing bolt 25 is advanced. After the fixing bolt 25 is tightened, the rear end face and the surface of the steering seat 24 are tightly in contact to complete the fixing of the clamping table 3. The design structure is simple, and circuit board bodies 35 of different lengths can be processed, with high versatility.
