Abstract
The utility model provides a furnace belt tensioning device of a solar wafer sintering furnace, which comprises a direction change roller (1) applied for a transmission furnace belt (2). The direction change roller (1) is located on one end of the circular head-tail-connecting furnace belt (2). The other end of the circular furnace belt (2) is sleeved on a driving roller (3) driven by a transmission motor (4). The furnace belt tensioning device is characterized in that the direction change roller (1) is connected with a tensioning mechanism. The tensioning mechanism can push the direction change roller (1) to move towards a direction far away from the driving roller (3). By equipping the tensioning mechanism on the direction change roller end and directly pushing the direction change roller to move through the tensioning mechanism, the furnace belt tensioning device then needs no additional reverse wheels, tensioners and supporting mechanisms thereof. Furthermore, the furnace belt tensioning device which basically needs no change in a vertical distance between the furnace belt and the ground has the advantages of simple compact structure and low manufacturing cost.

Solar cell mainly is made of silicon chip, and sintering is the final key technology that solar silicon wafers is made, and it is under action of high temperature, will be printed on the conductive metal layer sintering of silicon chip surface, contacts with the P-N knot of electrode thereby finish silicon chip.Silicon chip is placed on the furnace zone of high temperature sintering furnace circular flow, by the furnace zone transmission, finishes sintering through a plurality of warm areas of high temperature sintering furnace.The furnace zone is by the transmitting device transmission, and transmitting device comprises driving motor, drive roll, changed course cylinder, guide rail and support wheel, and the two ends in furnace zone are sleeved on drive roll and the changed course cylinder, and drive roll is driven by driving motor; The furnace zone, upper strata in the furnace zone of circular flow is by guide rail support, and the lower floor furnace zone is then supported by support wheel.Though there is the supporting of guide rail and support wheel in metal furnace zone, behind the long-play, can be out of shape loosely unavoidably, make to produce relative slip, the decline of furnace zone efficiency of transmission between furnace zone and two cylinders.At this problem, have at the drive roll end and increase tensioning apparatus, below drive roll, set up idle pulley and regulating wheel, the furnace zone, below of drive roll is S ground pile warp reverse idler gear and regulating wheel, regulating wheel is bearing in slidably on the bearing block, bearing block promotes mobile regulating wheel by hydraulic cylinder, thus the tensioning furnace zone.But this tensioning apparatus is comparatively complicated, need set up commutation idle pulley and regulating wheel and corresponding supporting construction, and must increase the height between furnace zone and the ground, the space that reverse wheel and regulating wheel are installed is just arranged, make the height of whole frame increase, not only cost greatly increases, and the freedom of movement of fuel manipulator crane tool arm is restricted, and also has further improved necessity.
The utility model content
For addressing the above problem, the utility model proposes a kind of furnace zone tensioning apparatus of solar silicon wafers sintering furnace, it is simple in structure, compact, and low cost of manufacture helps increasing the activity space of mechanical arm.
The purpose of this utility model is achieved in that a kind of furnace zone tensioning apparatus of solar silicon wafers sintering furnace, comprise the changed course cylinder that the transmission furnace zone is used, the changed course cylinder is positioned at an end in end to end annular furnace zone, the other end in described annular furnace zone is enclosed within on the drive roll that is driven by driving motor, described changed course cylinder is connected with strainer, and the strainer cylinder that can promote to alter course moves to the direction away from drive roll.
The utility model is provided with strainer at changed course cylinder end, directly promote the roller shifting that alters course by strainer, do not need to increase in addition idle pulley, regulating wheel and supporting mechanism thereof, help reducing the height between furnace zone and the ground, simple in structure, compact, low cost of manufacture helps increasing the activity space of mechanical arm.
As a kind of embodiment, described strainer comprises rack-mounted upper and lower chute, the two end supports of described changed course cylinder is on bearing block, the upper and lower end cunning of bearing block fits in the described upper and lower chute, described bearing block is connected with the piston rod end of hydraulic jack or cylinder, and hydraulic jack or cylinder and ground relative fixed ground are installed.Piston rod impeller-hub bearing by hydraulic jack or cylinder moves, and it is outwards mobile along the direction of upper and lower chute to drive the changed course cylinder again.
As another kind of embodiment, described strainer comprises the guide rail case that is provided with upper and lower guide rail, the guide rail case is connected with sintering furnace frame or ground, and the two end supports of described changed course cylinder is on bearing block, and the upper and lower end cunning of bearing block fits in the described upper and lower guide rail; Be fixed with the nut that axis parallels with upper and lower guide rail on the side of described guide rail case, screw mandrel one end connects with described bearing block after passing described nut.But being seated against in the upper and lower chute with regard to impeller-hub, screw mandrel rotation back moves, thus the tensioning furnace zone.
Beneficial effect:
The utility model directly promotes the roller shifting that alters course by strainer, not needing increases idle pulley, regulating wheel and supporting mechanism thereof in addition, helps reducing the height between furnace zone and the ground, simple in structure, compact, low cost of manufacture also can increase the activity space of fuel manipulator crane tool arm.
