Problems solved by technology

Initially, when the graphite boat was used in the industrial production of batteries, when some parts cracked or disconnected due to bumping, the conductive uniformity of the graphite boat would be reduced, and the color of the anti-reflection film prepared by deposition would be poor, so the graphite boat would be eliminated and replaced. Abandonment will seriously affect the production and processing cost and the finished product rate and yield rate of the product

Embodiment Construction

[0025] Example implementations will now be described more fully. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art.

[0026] The invention discloses a method for repairing a damaged graphite boat blade, comprising the following steps:

[0027] The blades of the damaged graphite boats are unloaded, and the blades can be carefully inspected after unloading, and it is judged whether they should be scrapped or repaired according to the damage.

[0028] According to the location, size and shape of the to-be-repaired blade of the damaged blade, a repaired area is set on the damaged blade, and the repaired area can be a plane or a thin linear area.

[0029] Cut off the damaged part along the repair area, and use the repai...

Abstract

The invention provides a method for repairing a damaged graphite boat blade. The method comprises the steps that a blade of the damaged graphite boat is demounted; a repairing area is set on the damaged blade; a damaged portion is cut off along the repairing area, a repairing tool is used to cut out a to-be-used part of a scrapped graphite boat blade, the to-be-used part and a cut to-be-repaired part can be combined into one complete blade and assembled on the graphite boat, and then calibration and repairing are conducted on a boat clamping mounting device; or, a patch piece is cut off from the scrapped graphite boat blade, the patch piece fixedly covers the two sides of a crack of a damaged portion in the repairing area, the graphite boat is assembled, and then calibration and repairingare conducted on the boat clamping mounting device; the repaired graphite boat is cleaned and dried; dummy silicon wafers are inserted into the repaired graphite boat, the repaired graphite boat is put into a tubular anti-reflection film deposition apparatus, and coating process is carried out; the dummy silicon wafers are taken out in order, according to the conditions of anti-reflection films ofthe dummy silicon wafers at each position, the position of the repaired part is slightly adjusted.

Description

technical field [0001] The invention relates to a method for repairing blades of graphite boats used for crystalline silicon cells. Background technique [0002] Against the backdrop of global warming and the depletion of fossil energy, the development and utilization of renewable energy has received increasing attention from the international community, and vigorously developing renewable energy has become the consensus of all countries in the world. The "Paris Agreement" came into effect on November 4, 2016, highlighting the determination of countries around the world to develop the renewable energy industry. [0003] Among all kinds of renewable energy, solar energy has become the fastest growing renewable energy due to its obvious advantages such as cleanness, safety, inexhaustibility and inexhaustibility. The development and utilization of solar energy is of great significance to adjusting the energy structure, promoting the revolution of energy production and consumpt...
