Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically a corner cutting machine for printed circuit board production. Background Technology

[0002] Circuit boards, also known as ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, and printed circuit boards, require the use of a circuit board corner cutting machine to cut the corners of the circuit boards during the production process.

[0003] Chinese patent disclosure for a corner-cutting machine for circuit board production, publication number CN221429205U, includes a base plate, a support frame mounted on the upper surface of the base plate, a telescopic cylinder mounted on the upper surface of the support frame, a support block mounted on the lower end of the telescopic cylinder, support rods mounted on the four sides of the support block, a corner-cutting blade mounted on the lower surface of one end of each support rod, and multiple docking mechanisms evenly embedded in the lower surface of each support rod; a placement mechanism is provided on the upper surface of the base plate inside the support frame; this invention uses a vacuum suction cup to fix the circuit board and a corner-cutting blade to cut the corners of the circuit board, allowing for simultaneous processing of all four corners; the corner-cutting blade is fixed by a first magnetic block and a second magnetic block, and multiple adjustable frames are mounted on the outside of the fixing base, enabling the placement mechanism to fix circuit boards of different sizes, and the adjustable corner-cutting blade facilitates corner cutting of circuit boards of different sizes.

[0004] However, it still has the following drawbacks: the device uses the suction force of the suction cup to position the center of the circuit board, but the fixation at the point where the circuit board leads are cut is poor, increasing the risk of cracking at the cold-cut position. Therefore, we propose a corner-cutting machine for printed circuit board production to solve this problem. Utility Model Content
