Description
Technical field
The utility model relates to a kind of aid that in the manufacture of solar cells process, uses, and is specifically related to a kind of plasma trimming anchor clamps that are used for silicon solar cell.
Background technology
Solar energy be do not have to pollute, regenerative resource easy to use, effectively utilize solar energy oneself through becoming human common recognition.In the process of development and utilization solar energy, people have developed solar cell, utilize photovoltaic effect directly to be electric energy to conversion of solar energy.In solar cell, silicon solar cell accounts for the main share in market.
Existing preparation silicon solar cell general flow is: surface clean and texturing, diffusion, plasma trimming, cleaning and removing phosphorosilicate glass, plated film, silk screen printing, sintering form ohmic contact, test.Wherein, in the solar cell diffusion process, diffusion impurity (like phosphorus) can be penetrated into the solar battery back surface, form the tow sides short circuit, and follow-up plasma trimming is just in order to eliminate this phenomenon.In plasma trimming process, generally need use a kind of aid---plasma trimming anchor clamps.
Existing plasma trimming anchor clamps mainly comprise lower cover, are symmetrically set in a pair of guide pillar at middle part, lower cover both sides and the upper cover plate that moves up and down along guide pillar, and guide pillar is provided with the nut of cooperation; In addition, for the ease of pipetting, be provided with handle at the end face of upper cover plate.
During use; Rotate two nuts earlier; Making has enough spaces between lower cover and the upper cover plate, then with 200 ~ 400 solar battery sheets neat be placed on this space, be placed on upper cover plate on the solar battery sheet lightly then; Again lightly firmly with nut screwing clamping, make between the battery sheet contact tight as far as possible; At last the above-mentioned anchor clamps that have solar battery sheet are put into the plasma etching machine trimming.
Yet; There is following problem in the plasma trimming anchor clamps of said structure: (1) is because above-mentioned anchor clamps only rely on a pair of guide pillar at middle part, both sides and tightening of nut to realize compressing of cover plate up and down; Cause the battery sheet middle stressed stressed bigger than its two ends; And then cause having the space between the edge of adjacent cell sheet, cause at follow-up plasma etching trimming process ionic medium body to the battery surface seepage, battery sheet surface is produced etching; Damage the battery sheet, cause the decrease in efficiency of battery sheet; Therefore (2), appear in the compaction process situation that produces fragment because of battery sheet discontinuity easily because above-mentioned anchor clamps only have a pair of guide pillar and nut; And, need to adopt the instrument of specific torsion in order to compress the battery sheet as much as possible, increased the fussy degree of operation.
Summary of the invention

Said suit comprises the suit lower cover, is symmetrically set at least 1 pair of suit guide pillar on suit lower cover both sides and the suit upper cover plate that moves up and down along the suit guide pillar, and the suit guide pillar is provided with the suit nut of cooperation;
Said suit guide pillar is positioned at the other both sides on the lower cover both sides at said guide pillar place;
Be provided with the location structure of cooperation between said upper cover plate and the suit upper cover plate.
In the preceding text; Said suit guide pillar is positioned at the other both sides on the lower cover both sides at said fixedly silicon chip anchor clamps guide pillar place; Be the suit guide pillar and fixedly silicon chip anchor clamps guide pillar be divided into the adjacent both sides of lower cover; Thereby be equipped with guide pillar or suit guide pillar on four limits of lower cover, and make its folded battery sheet stressed evenly, be difficult for producing fragment.
Optimized technical scheme, the guide pillar of said fixedly silicon chip anchor clamps has 3 pairs, is distributed in one group of opposite side of lower cover, and said suit guide pillar has 2 pairs, is distributed in another group opposite side of lower cover.
The effect of above-mentioned location structure: in the cover termination process of fixedly silicon chip anchor clamps and suit, location structure can be positioned at a fixing position with both, prevents that both from relative displacement taking place.Preferably, said upper cover plate is provided with boss, and the suit upper cover plate is provided with the hollow slots of cooperation, constitutes said location structure.
In the technique scheme, the upper cover plate of said fixedly silicon chip anchor clamps and the end face of suit upper cover plate are equipped with handle.
The course of work of the utility model is: fixedly on guide pillar, nut is screwed on the guide pillar through upper cover plate the upper cover plate of silicon chip anchor clamps, is the space that holds silicon chip between upper cover plate and the lower cover through guide pillar hole sleeve; At first several required battery sheets are put neatly lightly; Before and after it, all clip, be placed in the space between upper cover plate and the lower cover, then lightly earlier with a pair of nut screwing clamping in centre with backing plate; The self-contained battery sheet is then tightened other right nut again; Then; With reserving enough big space between the suit upper cover plate of suit and the suit lower cover; Fixedly the silicon chip anchor clamps are placed in the suit at leisure; Slowly tighten the cover loading nut then, make fixedly through location structure that silicon chip anchor clamps and suit fit together, at last that all nuts and suit nut screwing clamping is stressed.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the utility model is provided with the fixedly suit of silicon chip anchor clamps and cooperation; All be provided with guide pillar or suit guide pillar in four limits of cover plate up and down at anchor clamps; Form the multiple spot clamp structure; Make the folded battery sheet surface of anchor clamps stressed evenly, can folded highly stable the clamping of battery sheet be difficult for producing fragment.
2, the utility model can compress the battery sheet better, makes between sheet and the sheet edge of battery sheet the space very little, has reduced plasma to the solar battery sheet surface seep, helps the raising of the electrical property of solar cell; Experiment showed, that space between the battery sheet edge of the anchor clamps clamping that utilizes the utility model is that half of etching limit size of existing plasma trimming anchor clamps is less than.
3, the utility model is simple in structure, is convenient to preparation, and working service is convenient, is fit to promote the use of.
