Abstract
The invention discloses a novel copper block welding method. The method comprises the following steps: putting a plurality of copper blocks in a positioning plate; covering the surfaces of the copper blocks with a silk screen printing film; painting soldering paste on the silk screen printing film, wherein the soldering paste seeps to the surfaces of the copper blocks; taking down a silk screen and the copper blocks, sticking the copper blocks on a copper plate, and welding one surface, with the soldering paste, of each copper block to the copper plate by using a welding machine. The silk screen printing film is adopted to paint the soldering paste to the surfaces of the copper blocks, and a plurality of copper blocks can be painted in one time, so that the painting efficiency is high, and the painting is uniform. The conductivity of the welding surface of each copper block and the copper plate is improved, cold welding and pseudo welding are effectively avoided, the firmness between the copper blocks and the copper plate is increased, and the torque force after welding is greatly increased. The method has the advantages of being simple in process, good in filling effect and sealing performance and high in production efficiency.
Description
Technical field
The present invention relates to the copper billet welding of compound order seniority among brothers and sisters industry, specifically relate to a kind of new copper block welding method.
Background technology
In composite bus bar industry, copper billet is used for connecting the overlap joint between various power electric component or busbar widely.Usually, copper billet, in order to easy for installation, is welded on copper coin by people, and because copper conducts electricity very well, weld strength is high.Former traditional solder(ing) paste welding is smeared by solder(ing) paste on copper billet to implement welding, this method welding shortcoming; Irregular solder(ing) paste of smearing easily causes the uneven of the remaining solder(ing) paste of copper block surface, and the imperfect easy generation rosin joint of filling effect affects electric conductivity, easily produces pore, welding rear perimeter edge tin cream is unequal affects outward appearance, has a strong impact on production efficiency.
Summary of the invention
The present invention is directed to the problems of the prior art, a kind of new copper block welding method is provided.
For solving the problems of the technologies described above, the invention provides a technical scheme is: a kind of new copper block welding method,
(1) several copper billets are placed in location-plate;
(2) screen printed film is covered at copper block surface;
(3) be painted in screen printed film by solder(ing) paste, solder(ing) paste oozes to copper block surface;
(4) take off silk screen and copper billet and copper coin of being fitted by copper billet, adopt welding machine the one side with solder(ing) paste on copper billet to be soldered on copper coin.
Wherein, solder(ing) paste is evenly applied to the surface of copper billet, can avoid occurring rosin joint, improves welding effect.
Wherein, location-plate is provided with groove, and copper billet is placed in groove, the concrete size of copper billet sum, size and screen printed film that the size of groove is welded as required and determining, once can hold multiple copper billet in groove to carry out solder(ing) paste simultaneously and smear, thus improve whole work efficiency.
Copper billet is provided with locating hole, and copper coin is provided with endoporus, and when copper billet is soldered to copper coin, locating hole mates with endoporus and plays the role of positioning.
Welding machine is intermediate-frequency welding machine.
The invention has the beneficial effects as follows: adopt screen printed film that solder(ing) paste is applied to copper block surface, disposablely can smear multiple copper billet, it is high to smear efficiency, smears evenly, improve the electric conductivity of copper billet and copper coin solder side, effectively avoid rosin joint, dry joint, increases the fastness between copper billet and copper coin, increases the torsion after welding greatly, method is simple, its technique is simple, and filling effect, good airproof performance, production efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation that copper billet is positioned on location-plate;
Fig. 2 is the structural representation that copper billet is soldered on copper coin.
In figure: 1, location-plate, 2, copper billet, 3, locating hole, 4, copper coin.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is further described.
As shown in Figure 1, it is good first to be put by copper billet to the groove internal fixtion on location-plate, then covers above copper billet by screen printed film, then solder(ing) paste is placed brushing in screen printed film and infiltrate to copper block surface.
As shown in Figure 2, copper billet welds on copper coin by employing intermediate-frequency welding machine, copper billet is provided with locating hole, and copper coin is provided with endoporus and locates thus.
For a person skilled in the art; still can the technical scheme described in foregoing embodiments be modified; or equivalent replacement is carried out to wherein portion of techniques feature; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
