Description
Technical field
The utility model relates to fixture used when adopting laser to weld, specifically a kind of zinc-bromine flow battery fixture for laser welding.
Background technology
Zinc-bromine flow battery, as a kind of large-scale energy storage system, has long working life, the degree of depth lowers the features such as performance is good, cost is low, environmental friendliness, has vast potential for future development in fields such as renewable energy source access, distributed power generation and intelligent grids. But zinc-bromine flow battery also also exists some technical problems, one of them main problem is exactly the connection sealing problem between cell bipolar plate and pole plate frame and between barrier film and film frame. It is all a technical barrier that the framework of bipolar plates and its corresponding thermoplastic resin material of barrier film is tightly connected all the time, bipolar plate material is conductive plastics, under prior art, to being sealedly connected with multiple different welding process between bipolar plates from thermoplastic resin, conventional has the welding processs such as Vibration welding, ultra-sonic welded and thermo-welding.
Adopting Vibration welding soldering method, the easy drawing crack of pole plate frame and electrode welding interface, welding strength is not high. Adopt thermo-welding and ultra-sonic welded, the accurate control of welding region is had higher requirements, heat uneven and material spilling and can cause bipolar plates deformation, framework upper runner is easily damaged, mass flow discrepancy between each, affects the consistent performance of battery pile, and weld interval is long simultaneously, welding efficiency is low, this also increases manufacturing cost.
Practical novel content
In order to solve between zinc-bromine flow battery cell bipolar plate with pole plate frame and weld the problems referred to above of existence between barrier film with film frame, the purpose of this utility model is to provide a kind of zinc-bromine flow battery fixture for laser welding.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises base, lower backing plate, upper backing plate and top cover plate, wherein floor installation is in Laser Welding is received at the counter, being provided with lower backing plate on this base, described top cover plate is arranged on the cabinet that Laser Welding receives at the counter and covers, and this top cover plate is provided with can through the upper backing plate of laser;Being respectively equipped with lower backing plate boss and upper backing plate boss on described lower backing plate and upper backing plate, framework of welding to be welded for zinc-bromine flow battery is sandwiched in centre with upper backing plate boss by this lower backing plate boss.
Wherein: the shape of described lower backing plate boss is square, size is consistent with the part of the required welding of the bipolar plates of zinc-bromine flow battery; The shape of described upper backing plate boss is trapezoidal, and size is less than the part of the required welding of bipolar plates of described zinc-bromine flow battery; The upper surface of described base has the kerve of accommodating lower backing plate and multiple pilot hole for being fixed on base by described lower backing plate; The lower surface of described top cover plate has pickup groove that upper backing plate is fixed on the cover plate of top.
Advantage of the present utility model and positively effect be:
1. the utility model can accurate positioning welding region by upper and lower backing plate boss, uniform welding pressure can be provided during welding, ensure that the welding bipolar plates of framework with zinc-bromine flow battery or barrier film fully contact, weld more firm, Product jointing consistent performance is excellent, and quality product is secure.
2. the utility model operating process is easy, not easily produces detrimentally affect production caused by misoperation in welding process, and structure is simple, low cost of manufacture, welding efficiency height.
Accompanying drawing explanation
Fig. 1 is one of perspective view of the present utility model;
Fig. 2 is the two of perspective view of the present utility model;
Fig. 3 is the perspective view of backing plate on the utility model, top cover plate;
Wherein: 1 is base, 2 is pilot hole, and 3 is lower backing plate, and 4 is lower backing plate boss, and 5 is welding framework, and 6 is upper backing plate, and 7 is upper backing plate boss, and 8 is top cover plate, and 9 receive at the counter for Laser Welding, and 10 is cabinet lid.
Embodiment
