[0021] A cutting device for processing circuit boards includes a workbench 1, a cutting groove 2 is provided through the workbench 1, a fixed limit plate 3 and a group of movable limit plates 4 are provided on one side of the cutting groove 2, and a fixed block 5 and another group of movable limit plates 4 are provided on the other side. Two mutually perpendicular accommodating grooves 12 are provided on the workbench 1, and reciprocating screw rods 14 are rotatably provided inside the two accommodating grooves 12, and the outer ends of the reciprocating screw rods 14 pass through the side walls of the accommodating grooves 12 and are fixedly provided with adjusting buttons 15.

[0022] According to actual production needs, the distance between the movable limit plate 4 on the left and the cutting knife 9 is adjusted. A scale line 13 is also provided on the outer wall of the workbench 1. The scale line 13 indicates the distance between the cutting knife 9 and the movable limit plate 4 on the left, that is, it can indicate the length of each cutting of the circuit board. Turn the adjusting knob 15 to drive the reciprocating screw rod 14 on the left to rotate, so that the movable limit plate 4 on the left can be moved left and right, and then the cutting length can be adjusted according to the prompt of the scale line 13.

[0023] The left side of the large circuit board is close to the side wall of the fixed limit plate 3 and the fixed block 5. Turn the adjusting button 15 to drive the reciprocating screw rod 14 on the right to rotate, and then drive the movable limit plate 4 on the right to approach the side wall of the circuit board. It can play a role in aligning circuit boards of different widths, avoiding the deviation of the circuit board during cutting, so that the circuit board can be manually pushed between the two movable limit plates 4 and between the fixed limit plate 3 and the fixed block 5, and the circuit board is pushed according to the cutting process.

[0024] The two groups of movable limit plates 4 are arranged perpendicular to each other, and the outer walls of the two reciprocating screw rods 14 are respectively threadedly connected with the movable limit plates 4. The movable limit plates 4 on the same side as the fixed block 5 are L-shaped structures, and the movable limit plates 4 away from the fixed block 5 are vertical plate structures and are parallel to the fixed limit plates 3. The fixed limit plates 3 and the movable limit plates 4 on the right side together align the width side walls of the circuit board.

[0025] A telescopic push plate 10 is provided inside the fixed block 5, and a telescopic pressure plate 11 is provided on the movable limit plate 4 on the same side as the fixed block 5. A groove 16 is provided on the inner wall of the fixed block 5, and an electric telescopic rod 17 is fixedly provided on the side wall of the groove 16 and the top wall of the movable limit plate 4. The telescopic ends of the electric telescopic rod 17 are respectively fixedly provided with the telescopic push plate 10 and the telescopic pressure plate 11.

[0026] By starting the electric telescopic rod 17, the telescopic pressing plate 11 can be driven to approach and contact the top wall of the circuit board, pressing and fixing it to prevent the circuit board from shifting during cutting.

[0027] A reciprocating screw rod 7 is provided above the cutting groove 2, and a cutting knife 9 is threadedly connected to the outer wall of the reciprocating screw rod 7. Support plates 18 are fixedly provided on the top walls of the workbench 1 on both sides of the cutting groove 2.

The reciprocating screw rod 7 is rotatably provided between the support plates 18, and one section of it is also provided at the output end of the forward and reverse motor 19.

[0028] Start the forward and reverse motor 19 to drive the reciprocating screw rod 7 to rotate in the forward and reverse directions. Since the outer wall of the reciprocating screw rod 7 is threadedly connected to the moving seat 20, a servo motor 21 is provided at the bottom end of the moving seat 20. The cutting knife 9 is provided at the output end of the servo motor 21, which can perform rotational cutting on the circuit board. The rotation of the reciprocating screw rod 7 in the forward and reverse directions further enables the moving seat 20 to achieve reciprocating motion along the reciprocating screw rod 7. During the reciprocating motion, the servo motor 21 is started at the same time, which can drive the cutting knife 9 to perform rotational cutting on the circuit board.

[0029] A collection box 6 is movably positioned on the outer side of the fixed block 5. This box opens upward and is movably positioned beside the workbench 1. Activating the electric telescopic rod 17 drives the telescopic push plate 10 to push the cut circuit boards into the collection box 6. A waste bin 8 is provided below the cutting trough 2. This waste bin 8 has an open top structure, and its top opening is located directly below the cutting trough 2. Debris generated during cutting falls directly through the cutting trough 2 into the waste bin 8 below, preventing debris from accumulating on the workbench 1 and affecting cutting efficiency.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
