Abstract

The invention relates to the technical field of circuit board processing, in particular to a printed circuit board etching device which comprises a feeding conveyor; a discharging conveyor; an etching box; and a positioning, overturning and conveying mechanism. The positioning, overturning and conveying mechanism comprises two groups of translation assemblies arranged on the two sides above the etching box, a synchronous assembly is arranged between the two translation assemblies, an overturning frame is arranged between the two translation assemblies, the two sides of the overturning frame are in transmission connection with the working end of each translation assembly, and a lifting plate is arranged at the bottom of the overturning frame; and two clamping parts are arranged at the top of the lifting plate, each clamping part comprises a [-shaped frame, first synchronous wheels are arranged on the two sides of the interior of each [-shaped frame, and a plurality of protruding parts are arranged on the exterior of each synchronous belt. A circuit board is driven to translate repeatedly through the protruding parts arranged on the two first synchronous belts, so that the circuit board is fully etched during etching, and the etching precision and integrity of the circuit board are improved.

Description

technical field [0001] The invention relates to the technical field of circuit board processing, in particular to a printed circuit board etching device. Background technique [0002] Printed circuit boards are extremely important components in electronic equipment. In order to better process the surface of the circuit board, the circuit board needs to go through many processes in the manufacturing process before the finished product can be prepared. Among them, the etching process of the circuit board is one of the most critical processes in the whole manufacturing process of the circuit board. line. [0003] When an existing etching machine etches a circuit board, the circuit board is clamped by a clamp and immersed in an etching solution, so that the etching solution etches the circuit board. During the etching process, the clamped part of the circuit board is blocked by the fixture, and the etching solution cannot etch the part, and the circuit board cannot be complet...
