Intelligent tin soldering equipment for production of integrated circuit board of liquid crystal display screen

Abstract

The invention relates to the technical field of intelligent tin soldering equipment, in particular to intelligent tin soldering equipment for production of an integrated circuit board of a liquid crystal display screen, which comprises a tin soldering workbench, a mounting frame is welded on the upper side of the tin soldering workbench, and a first bearing hole is formed in the lower side of one end of the mounting frame; two supporting rotating rods are symmetrically welded to the upper side of the first bearing hole, limiting round blocks are welded to the ends of the supporting rotating rods, a shaft hole is formed in the lower side of the other end of the mounting frame, the shaft hole and the first bearing hole are coaxial, and a second bearing hole is formed in the lower side of the shaft hole; before welding, the tin soldering device moves downwards to a working position under the action of an electric telescopic rod, meanwhile, a protective door pocket is driven to be movably connected to the working position in a sleeving mode under the action of a rotary connecting plate on the electric telescopic rod, and then a protective plate is driven to rotate to a vertical state to be closed with the protective door pocket under the action of a rack and meshing teeth; therefore, the phenomenon that the solder paste splashes to hurt people is avoided.

[0002] The production process of liquid crystal display is becoming more and more intelligent. When the integrated circuit board in the liquid crystal display is being welded, in order to improve its welding efficiency, intelligent soldering equipment will be used to weld the circuit board. Smart equipment The use makes the welding work very simple and liberates manpower to a large extent. However, the intelligent soldering equipment used in the production of integrated circuit boards still has certain deficiencies in actual work. The lack of protective devices will lead to the phenomenon of solder paste splashing and hurting people. In addition, the positioning device needs to be used to fix the circuit board at the working position before welding to ensure the smooth progress of the welding work. However, the positioning device on the current intelligent soldering equipment is not It is possible to position and fix circuit boards of different sizes, resulting in the need to use different soldering equipment or replace the positioning device for welding circuit boards of different sizes, which increases the cost of welding, and the operation of the positioning device is troublesome, which affects the integrity of the integrated circuit board. Fixed efficiency, and the welding of the circuit board needs to be welded on both sides, and when welding the other side of the circuit board, the circuit board needs to be disassembled from the positioning device and turned over for installation, and then soldered. Such an operation is undoubtedly very Troublesome, it greatly affects the welding efficiency of the circuit board
