Wave soldering fixture for automatically soldering intelligent water meter

Abstract

The invention discloses a wave soldering fixture for automatically soldering an intelligent water meter. The wave soldering fixture comprises a bottom plate, a synthetic stone plate, a lower limiting plate, an upper limiting plate and a gland; the synthetic stone plate, the lower limiting plate, the upper limiting plate and the gland are sequentially arranged on the bottom plate; a plurality of soldering and accommodating grooves for placing CPU plates are formed in the synthetic stone plate on which the lower limiting plate is mounted; hollow holes for accommodating and limiting the CPU plates and hollow holes for accommodating and limiting GDB plates are formed in parts, corresponding to the soldering and accommodating grooves, on the lower limiting plate; the upper limiting plate is mounted on the lower limiting plate; hollow holes for accommodating and limiting GDB plates are formed in parts, corresponding to the soldering and accommodating grooves, on the upper limiting plate; and the gland is mounted on the upper limiting plate. A high-temperature-resistant synthetic stone material is used for manufacturing a carrier plate, the gland ensures that the GDB plates are completely close to the CUP plates, the horizontal shaking of the CPU plates is limited by the lower limiting plate, the horizontal shaking of the GDB plates is limited by the upper limiting plate, the GDB plates are in contact with the CPU plates at zero distance, and overfurnace soldering is adopted to form a relatively good soldering point, so that the production efficiency is increased.

Description

technical field [0001] The invention relates to a wave soldering fixture for automatic soldering of an intelligent water meter. Background technique [0002] At present, wave soldering refers to the molten solder (lead-tin alloy) sprayed by an electric pump or an electromagnetic pump into a solder wave peak required by the design. It can also be formed by injecting nitrogen into the solder pool, so that the components pre-installed The printed board of the device passes through the solder wave to realize the soldering of the mechanical and electrical connection between the solder end of the component or the pin and the pad of the printed board. In the soldering process, in order to ensure that the printed board (also known as the CPU board) does not deform when it passes through the tin furnace or cannot pass the rail due to its small size, a jig for carrying the CPU board is commonly used, which is called wave soldering.

Problems solved by technology

In the soldering process, in order to ensure that the printed board (also known as the CPU board) does not deform when it passes through the tin furnace or cannot pass the rail due to its small size, a jig for carrying the CPU board is commonly used, which is called wave soldering. Fixtures or flow soldering fixtures, this kind of fixtures are generally processed and customized according to needs, and the versatility is poor. Once a new board is replaced, it must be re-made, and the original board will be discarded. This not only wastes resources, but also requires replacement. Finally, it is necessary to adjust the guide rail distance according to the size of the new board, which is not only inconvenient to operate, but also increases the operating and maintenance costs of the enterprise.
