A kind of welding hold-down mechanism that can compatible multiple photovoltaic crystal silicon battery sheet
Technical field
The utility model relates to a kind of welding hold-down mechanism that can compatible multiple photovoltaic crystal silicon battery sheet, specifically be to link to promote briquetting by three cylinders to push down welding, three briquettings are controlled separately by three cylinders respectively, effectively avoided pressing down the problem of pressure distribution inequality in the process, guaranteed that every welding can both firmly be pushed down; In addition, briquetting can carry out the spacing adjustment by four U-shaped holes on the fixed head of upper strata, therefore, this mechanism can be applicable to two grid line battery sheets, three grid line battery sheets and the multiple-grid line battery sheet of different area, different-thickness, and is applicable to the battery sheet that all main grid line sizes of space are different.
Background technology
The welding hold down gag of present most of series welding machine all adopts single-cylinder to press the method for single briquetting, be that cylinder promotes single briquetting and directly pushes down all weldings, certainly will bring some problems like this, if the briquetting surface treatment is not very desirable, will cause the pressure inequality, and single briquetting to push down all weldings, so the long enough that must do of briquetting, yet the more long more easy deformation that occurs of briquetting, in case the phenomenon that briquetting deformation will occur not pressing tightly in long use.
Summary of the invention
The utility model relates to a kind of welding hold-down mechanism that can compatible multiple photovoltaic crystal silicon battery sheet, and this mechanism is made up of upper strata fixed head, lower floor's fixed head, pressure block, four columns, three briquettings and three cylinders; Specifically be that three cylinders are controlled three independently briquettings respectively, three briquettings press down simultaneously after the cylinder work, guarantee that each root bead band is all firmly pushed down; Briquetting can carry out the spacing adjustment by four U-shaped holes on the fixed head of upper strata, therefore, this mechanism can be applicable to two grid line battery sheets, three grid line battery sheets and the multiple-grid line battery sheet of different area, different-thickness, and is applicable to the battery sheet that all main grid line sizes of space are different.
The technical solution of the utility model is: a kind of welding hold-down mechanism that can compatible multiple photovoltaic crystal silicon battery sheet, formed by upper strata fixed head (1), lower floor's fixed head (2), pressure block (3), column (4), briquetting (5), cylinder (6); Upper strata fixed head (1) and lower floor's fixed head (2) are fixing by near the circular hole (7) its four summits and four root posts (4), form main frame, cylinder (6) is fixed under the upper strata fixed head (1) by 4 the U-shaped holes (8) on the fixed head of upper strata, three briquettings (5) are separately fixed under three separate cylinders (6), and pressure block (3) is fixed on directly over lower floor's fixed head (2) by its two mother rib lateral rotundum (10); Briquetting (5) is three independently individualities, is separately fixed at three separate cylinders (6) below; And briquetting (5) can carry out the spacing adjustment by 4 U-shaped holes (8).
The utility model has the advantages that:
1. the utility model adopts three separate cylinders, guarantees that every root bead band can both firmly be pushed down.
2. briquetting can carry out the spacing adjustment by four U-shaped holes on the fixed head of upper strata, therefore goes for various different specification of battery sheets.
3. the utility model adopts three independent briquettings, and compare and use the hold down gag of single briquetting, more difficult generation deformation, also more durable.
