Abstract

The invention relates to an improvement method for crystal rod cutting, which belongs to the technical field of photovoltaic processing. The improvement method of the crystal rod cutting adopts the technical scheme that a 1-2mm distance is reserved between crystal rods for adhering rods; resin strips are used for separately adhering the crystal rods; a line separation net device is mounted and hung on a machine outer wall; the line separation net is regulated to control the line net width within a range of 5-6 mm; a steel line is in the middle of a crevice of the separated line net and is repaired under a guide wheel with textured adhesive. The improvement method for the crystal rod cutting ensures that the reserved line net is larger than a crystal rod seam, and the generated benefits are superior to that in the prior part; the line separation net lowers head and tail sheet generated by the original cutting; qualified products are directly produced; the line separation net effectively reduces break of the line net because of the head and tail sheet; the line breaking rate is greatly lowered; the utilization rate of single-cutter equipment is improved; and the original cutting length 780 mm/cut is improved to 805 mm/cut.

Description

Improving one's methods of crystal bar cutting

Technical field

The invention belongs to the photovoltaic processing technique field, relate in particular to improving one's methods of a kind of crystal bar cutting.

Background technology

Fast development along with photovoltaic industry, the competitive pressure of international level, increasing silicon chip cutting enterprise wants to survive and has the factor of merit that reduces production costs, improves the silicon chip cutting only and enhance competitiveness, technique and the operating process of each company's silicon chip cutting are roughly the same at present, how could under identical technique and flow process, obtain better benefit, just need to pay close attention to details, do improvement in tiny operating aspect, drop to the loss in production process minimum.

Crystal bar is fixed on cutting bed, common one time 4, cutting bed vertically, by the line of cut cutting net of motion, makes crystal bar be cut into silicon chip.It is very simple that incision principle seems, but a lot of challenges are arranged in actual mechanical process, the necessary accurate balance of scroll saw and control line of cut diameter, cutting speed and total cutting area, thereby in the chip-proof situation of silicon chip, the silicon wafer thickness of agreeing, and shorten clipping time.Current silicon chip cutting process, the crystal bar two ends all can produce in a large number sheet end to end, and crystal bar is not reasonably utilized.

Summary of the invention

For above-mentioned technical problem, the invention provides improving one's methods of a kind of crystal bar cutting.

For solving the problems of the technologies described above, the technical scheme adopted of improving one's methods of crystal bar cutting of the present invention is:

(1) seam sky between crystal bar and crystal bar is stayed 1mm-2mm apart from sticky stick, resin streak separately pastes sticky crystal bar;

(2) the separated time net arrangement is installed, is suspended on the machine outer wall, adjust the separated time net arrangement gauze width is controlled between 5mm-6mm;

(3) steel wire of an inclination is arranged in the middle of the gauze crack after separately, repair to guide wheel with U.S. line glue.

Improving one's methods of crystal bar cutting of the present invention, when crystal bar cuts, adopt the separated time net arrangement that the gauze width is controlled between 5mm-6mm, guarantee that the empty gauze stayed is larger than crystal bar seam, divide the gauze cutting technique to increase operation than origin operation technology, operational sequence can increase additionally consuming time, but the benefit produced is better than former technique: minute gauze reduces the sheet end to end that original cutting produces; Directly produce certified products; Divide gauze effectively to reduce the gauze broken string that the excuse cauda causes, greatly reduce outage; Improve the utilization rate of hilted broadsword equipment, by former Cutting Length 780mm/ cutter, bring up to the 805mm/ cutter.

The specific embodiment

Below in conjunction with embodiment, the present invention is made and further illustrating.

Improving one's methods of crystal bar cutting of the present invention, concrete operation step and points for attention:

Be applicable to various novel slicers and cut apart gauze as DS264, DS271, PV800 etc.

Adopt wireless remote control handle, operation separated time net cutting in more skilled situation, thereby prevent from when crystal bar from clamping producing the limit situation that collapses that glass breakage causes that crystal bar differs in size, between crystal bar and crystal bar the seam sky stay 1mm-2mm apart from sticky stick, and resin streak separately pastes sticky crystal bar, the gauze width is controlled between 5mm-6mm, guarantees that the empty gauze stayed is larger than crystal bar seam; In order to prevent machine under the cutter cutter, the gauze that sky stays must be larger than the long-pending seam of crystal bar, if long-pending being sewed with of crystal bar has greatly hour, would rather saw a little more, and indispensable saw, (in the unequal-sided situation of crystal bar), otherwise can increase steel wire wear, cause the quality of this cutter product; In the middle of gauze crack separately, have the steel wire of an inclination, repair to the guide wheel below with U.S. line glue.

For the difference of every bit manipulation personnel pressure bar technology, thereby it is not in place when pressure bar, to can't see the linear slit pressure bar of back, and the method for existing available touch gauze is carried out pressure bar, and the first contact wire wire side of the crystal bar of take is benchmark.

Obtained effect:

Divide the gauze cutting technique to bother manyly than the origin operation technology, operating personnel may feel trouble and not note, facts have proved that in fact a minute gauze obtains benefit also a lot:

Divide gauze to greatly reduce the sheet end to end that original cutting produces;

Dividing gauze can reduce steel wire rubs at former crystal ingot limit face;

Minute gauze can effectively reduce the gauze broken string that the excuse cauda causes, and in former cutting process, thickness can often produce end to end swings greatly line, can greatly reduce outage;

Thereby the raising factor of merit, and yield rate;

The crystal bar total length increases, and can increase the product piece rate.

The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; it should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.

Claims (1)

1. improving one's methods of crystal bar cutting is characterized in that comprising the following steps:

(1) seam sky between crystal bar and crystal bar is stayed 1mm-2mm apart from sticky stick, resin streak separately pastes sticky crystal bar;

(2) the separated time net arrangement is installed, is suspended on the machine outer wall, adjust the separated time net arrangement gauze width is controlled between 5mm-6mm;
