Problems solved by technology

[0004] Chinese patent (CN202037628U) is a printed circuit board cutting device, which specifically discloses a cutting method for circuit boards. However, the circuit board cutting machine will generate some dust during the process of cutting circuit boards. Precision components have high requirements on temperature, humidity and dust. Obviously, if this part of dust falls on the circuit board, it will have a great impact on the use of the circuit board.

Abstract

The invention provides circuit board cutting equipment based on a dust adsorption principle. The circuit board cutting equipment comprises a baseplate, wherein a circuit board is placed on the baseplate; two electric push rods are fixedly connected with the left and right ends of the baseplate; a top plate is fixedly connected with the top ends of the electric push rods jointly; a moving groove ofwhich the opening faces down is formed in the top plate; a moving block is arranged in the moving groove; a threaded through hole is formed in the moving block; a threaded rod is in threaded connection with the interior of the threaded through hole; two ends of the threaded rod are rotationally connected with two ends of the moving groove; the right end of the threaded rod is fixedly connected with an output shaft of a motor; a cutting motor is fixedly connected with the lower side of the moving block through a connecting column; a cutter is fixedly connected onto an output shaft of the cutting motor; and a protective hood is arranged on the outer side of the cutting motor in a covering manner. The circuit board cutting equipment provided by the invention has the following beneficial effects: outside air is blown by an air blower into an air distribution cavity through a first hose, and the blown air is jetted through a warped part, so that dust can move up, can enter the protective hood, and can be prevented from falling onto the circuit board.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a circuit board cutting device based on the principle of dust absorption. Background technique [0002] A circuit board refers to a device made by utilizing and controlling the laws of electronic motion in a vacuum, gas or solid. Divided into electric vacuum devices, gas-filled tube devices and solid-state circuit boards. In the analog current, it is used for rectification, amplification, modulation, oscillation, frequency conversion, phase locking, control, correlation, etc.; in the digital current, it is used for sampling, limiting, logic, storage, counting, delay, etc. The gas-filled tube device is mainly used for rectification , Voltage stabilization and display purposes, solid-state circuit boards such as integrated current. [0003] The circuit board cutting machine can cut and disconnect the circuit board, and can also perform "V" groove cutting on the circuit boa...
