Automatic welding device for flow line

Abstract

The invention discloses an automatic welding device used for a production line, aims to provide a production line used automatic welding device with the advantages of simple structure, accurate positioning, high automaticity and stable and reliable performance. The automatic welding device used for the production line of the invention includes a bracket, a guide rail arranged on the bracket for carrying a trolley, and a tin pot for storing tin liquor; and a small tin pot is arranged in the tin pot and is connected with a mobile which can reciprocate in a vertical direction. The automatic welding device is applicable to the large-size and production-line-type circuit board soldering process, and is the substitute for the prior automatic welding device used for the production line.

Description

Technical field [0001] The invention relates to a device for manufacturing a circuit board, and more specifically to a device used in the soldering process of the circuit board. Background technique [0002] In the current electronics industry, the soldering process of circuit boards is generally arranged on the production line. In the soldering process of the circuit board, the soldering process generally adopts the following methods: 1. All manual soldering methods are used. This is greatly affected by the skill level of the welding operator, and the efficiency of the operation is very low, so the quality and effect of the welding cannot be effectively guaranteed; 2. Using wave soldering, the circuit board moves horizontally, and the bottom surface contacts the tin liquid. In order to complete the soldering process, the soldering quality is not guaranteed, and the soldering liquid is seriously wasted; 3. The soldering adopts the old-fashioned dip soldering method, which means t...

Problems solved by technology

[0002] In the current electronics industry, the welding process of circuit boards is generally arranged on the production line. In the soldering process of circuit boards, the soldering process generally adopts the following methods: 1. All manual welding methods are used. This is greatly affected by the skill level of the welding operator, and the efficiency of the operation is very low, so the quality and effect of the welding cannot be effectively guaranteed; In this way, the welding process is completed, so the welding quality is not guaranteed, and the solder liquid is seriously wasted; 3. The welding adopts the old-fashioned dip soldering method, that is, the container for storing the tin liquid is fixed, and the circuit board is moved downward so that the welding surface reaches the surface of the tin liquid Under, so as to achieve the purpose of soldering

The disadvantage of this is that the circuit board moves up and down, which is not easy to operate, and the area of ​​the soldering surface of the circuit board does not match the upper surface area of ​​the container storing the tin liquid, so it is easy to waste the tin liquid; at the same time, the container for storing the tin liquid after soldering There are more impurities on the upper surface, which is not conducive to the soldering of the next circuit board

All in all, the soldering equipment in the prior art has a complex structure, inconvenient maintenance, and poor operability, which greatly reduces the production efficiency of the welding assembly line, and wastes raw materials at the same time, which is not conducive to the control of production costs
