Problems solved by technology

During laser soldering, due to the small area of ​​the pad, the precision soldering needle is prone to deviation. Once the deviation occurs, it is easy to break the needle or scrap the product to be welded during the process of lowering the needle for soldering; The tin structure is complicated, and the operation of pouring the finished solder paste is cumbersome and time-consuming

Embodiment 1

[0034] On the basis of the above structure, in this embodiment, the sealing member is a locking screw 2 , and the lower end of the locking screw 2 is screwed to the upper end of the tin pot 1 . The locking screw 2 is threadedly connected with the upper end of the tin filling cylinder 1, which facilitates the opening and closing of the tin filling cylinder 1, which is easy to operate, saves time and effort, and greatly improves production efficiency.

[0035] The above-mentioned locking screw 2 acts as a seal, that is, the upper end of the tin filling cylinder 1 is provided with an internal thread, and the lower end of the locking screw 2 is threadedly connected with the upper end of the tin filling cylinder 1 to seal the upper end of the tin filling cylinder 1 .

Embodiment 2

[0037] On the basis of the above structure, in this embodiment, the sealing member is a sealing cover, and the sealing cover is screwed to the upper end of the tin pot 1 . The sealing cover is threadedly connected with the upper end of the tin filling cylinder 1, so that the opening and closing of the tin filling cylinder 1 is convenient, the operation is simple, time-saving and labor-saving, and the production efficiency is greatly improved.

Embodiment 3

[0039] On the basis of the above structure, this embodiment also includes a horizontally arranged bottom plate 3 that can move up and down. The tin filling tube 1 is fixed on the bottom plate 3 by welding or bolts, and the tin filling tube 1 is installed through the bottom plate 3 to increase the tin filling tube. 1 The stability of installation and up and down movement.

Abstract

The invention relates to a precise needle head with an anti-collision function. The precise needle head with the anti-collision function comprises a tin filling cylinder, the tin filling cylinder is vertically arranged in a vertically movable mode, the upper end of the tin filling cylinder is open and detachably connected with a sealing piece, and the lower end of the tin filling cylinder is provided with a discharging port. The precise needle head with the anti-collision function has the advantages that the structure is compact, finished tin paste canning is convenient and fast, and the production efficiency is greatly improved; and meanwhile, needle head collision in the tin soldering process can be effectively prevented, and the product welding quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a precision needle with anti-collision function. Background technique [0002] With the development of wire processing technology and technology, the size of connectors, printed circuit boards and terminals is further miniaturized, and the requirements for wire transmission quality and speed continue to increase. Laser soldering gradually replaces traditional electric soldering iron soldering and hot-press melting soldering, while As a common component of laser soldering equipment, precision tin dispensing needles have been widely used in the field of laser soldering. During laser soldering, due to the small area of ​​the pad, the precision soldering needle is prone to deviation. Once the deviation occurs, it is easy to break the needle or scrap the product to be welded during the process of lowering the needle for soldering; The tin structure is complicated, and the opera...
