[0006] A main control circuit board cutter comprises a base, four corners of the bottom end of the base are provided with columns, a first mounting plate and a second mounting plate are fixedly mounted on both sides of the base, a first cylinder is fixedly mounted on the top end of the first mounting plate, a push limit assembly is provided on the end of the piston shaft of the first cylinder, a support frame is fixedly mounted on the top end of the base, a through slot is opened on the top end of the base, the through slot is located below the support frame, a distance measuring assembly is provided between the second mounting plate and the support frame, and a clamping assembly is provided in the support frame;

[0007] A support box is fixedly installed on the inner wall of the top of the support frame, a support block is slidably installed in the support box, the bottom end of the support block slides through the support box and is provided with a cutting assembly, the side wall of the support block is provided with a driving assembly, a suction fan is fixedly installed on the bottom end of the base, and a dust suction and filtering assembly is provided between the suction fan and the through slot.

[0008] By adopting the above technical solution, when the equipment is used, the staff places the circuit board on the base, clamps one end of the circuit board by pushing the clamping assembly, and then drives the circuit board to move by the first cylinder, which is conducive to maintaining the stability of the movement of the circuit board. The distance measuring assembly is set between the second mounting plate and the support frame to play the role of positioning and measuring the length of the circuit board to be cut, which is convenient for the equipment to cut circuit boards of different sizes. When the circuit board moves to the bottom of the support frame, the clamping assembly is operated to clamp and fix the circuit board, which is conducive to maintaining the stability of the circuit board during cutting, and thus helps to maintain the quality of the circuit board cutting.

Dust may be generated when the equipment cuts the circuit board. The suction fan generates suction to allow the dust to pass through the through slot into the dust collection filter assembly, which can collect dust and help prevent dust from affecting the subsequent cutting of circuit boards.

[0009] Furthermore, the pushing limit assembly includes a push plate fixedly mounted on the end of the piston shaft of the first cylinder, and two symmetrically distributed support plates are fixedly mounted on the side of the push plate away from the first cylinder, a limit plate is provided between the two support plates, and pillars are fixedly mounted on the opposite sides of the two support plates, and movable grooves are opened on the opposite sides of the two pillars, and support rods are slidably mounted in the two movable grooves, and the opposite ends of the two support rods are fixedly connected to the side opposite to the limit plate on the same side, and springs are fixedly connected between the opposite ends of the two support rods and the inner wall of the side opposite to the movable groove on the same side.

When the circuit board is located between the two limit plates, the limit plate pushes the support rod on the same side to slide in the movable groove on the same side, and the support rod pushes the spring on the same side to contract. When the circuit board is placed, the support rod pushes the limit plate to move under the elastic force of the spring on the same side.

[0016] By adopting the above technical solution, when the circuit board moves to the bottom of the support frame, the third cylinder drives the mounting rod on the same side to slide with the two connected moving rods, and the moving rod moves with the clamping plate on the same side. Through the cooperation of multiple clamping plates, the circuit board is clamped and fixed, which helps to avoid offset when cutting the circuit board and is conducive to maintaining stability when cutting the circuit board.

[0017] Furthermore, the cutting assembly includes a telescopic rod fixedly mounted on the bottom end of the support block, a connecting block fixedly mounted on the end of the telescopic rod, a protective box fixedly mounted on the bottom end of the connecting block, a second reduction motor fixedly mounted in the protective box, a connecting column fixedly mounted on the end of the output shaft of the second reduction motor, the connecting column rotates away from one end of the second reduction motor and penetrates the protective box, and the connecting column penetrates the side wall of one end of the protective box and is fixedly sleeved with a cutting blade.

[0018] By adopting the above technical solution, when the positioning and clamping of the circuit board is completed, the second reduction motor drives the connecting column to rotate, and the connecting column drives the cutting blade to rotate.
