A kind of convenient replacing battery lead rod electrode block prevents the device of shielded-plate tube plated film exception
Technical field
The utility model belongs to thin film solar photovoltaic cell technical field, is applied to the maintenance of PECVD work rest, and particularly a kind of convenient replacing battery lead rod electrode block prevents the device of shielded-plate tube plated film exception.
Background technology
At present, for making each electrode coating process in cvd furnace keep stability, need the electrode contact of plasma enhanced chemical vapor deposition device necessary good.Therefore, require regularly irregularly to carry out work rest maintenance.In work rest maintenance process, easily there is loosening oxidization condition in the connection of frequent discovery battery lead rod and electrode block and electrode block and positive plate, cause conducting resistance to increase, current capacity declines, and then easily occurs reflection, bad, the too low situation of power of plated film in process.Because working space is narrow and small, on existing electrode block, on three countersunk head screws and existing electrode block insulation booth, four hexagon socket head cap screws are difficult to dismounting and install and electrode block insulation booth sealing property is not good.
In addition, come out of the stove at work rest, blanking, in moving process, the rete that plated film is formed can come off and form silica flour etc., therefore during work rest cleaning, the water jets under high pressure of water blast gun ejection is mingled with silica flour etc. and likely enters in electrode block insulation booth and between insulation booth gap, so just for PECVD plated film has buried hidden danger: during plated film, because before electrode block, the shielded-plate tube at tetrafluoro block place is completely out exposed, do not take effective preventive measures, reflection is there is under superposition of electric field, cause the abnormal plated film of shielded-plate tube, have a strong impact on technique to proceed, cause product power too low, even scrap.So work rest spends more time and manpower to go to carry out the process of the abnormal plated film of shielded-plate tube before using next time, due to the obstruction of the lead screw of fixed side and narrow space, cause two of shielded-plate tube support fastening shielded-plate tube bolt disassembly on aluminium blocks utilize existing instrument carry out operating very inconvenient, and the access times of meeting serious curtailment shielded-plate tube and electrode side plate, increase the cleaning frequency of work rest, thus cause the costs such as human and material resources to increase.
