Circuit board one-time welding device

Abstract

The invention provides a circuit board one-time welding device. The circuit board one-time welding device comprises a long barrel-shaped heating cavity, wherein a long strip-shaped heating plate is assembled inside the heating cavity, a feeding port of a soldering tin cylinder right faces the heating plate and is communicated with the heating cavity through a guide sleeve, a through hole corresponding to the soldering tin cylinder is machined in the middle of the guide sleeve in the axial direction, an advancing block used for pushing the soldering tin cylinder into the heating cavity is assembled on the guide sleeve, and conical outlets arranged side by side axially are machined in the cavity wall of the heating cavity. The circuit board one-time welding device is used for carrying out welding operation on a circuit board. According to the welding method, soldering tin is extruded from the conical outlets designed in advance, the welding position is more accurate, raw materials are extruded through the advancing block, the use amount of the raw materials is more accurate, and the welding effect is better.

Description

technical field [0001] The invention relates to the technical field of electronic equipment production, in particular to a circuit board primary welding device. Background technique [0002] When producing and connecting electronic equipment, especially communication machines, flexible circuit boards are often used for connection. Flexible circuit boards are usually used to connect the main board and the display and sound modules of electrical appliances. The connection position is usually designed with a row of single connectors exposed side by side, like the cable we often use to connect the flip phone or laptop display to the motherboard. Soldering is usually used to connect these cables to electronic devices such as motherboards and display screens. These weldings are usually done using large-scale automation equipment on the production line, but if the electronic equipment that uses the cable is produced in small batches, or when performing maintenance on a single prod...

AI Technical Summary

Problems solved by technology

These weldings are usually done using large-scale automation equipment on the production line, but if the electronic equipment that uses the cable is produced in small batches, or when performing maintenance on a single product, the cost of welding with large-scale automation equipment will be too high. At this time, people usually Use an electric soldering iron to complete the welding by single point one by one. This welding method is inefficient, and it is easy to cause electrical connection between different soldering points during the welding process, resulting in wrong connection of the entire circuit.
