Utility model content
The purpose of this utility model is, provides a kind of photovoltaic welding belt high accuracy air knife.
According to an aspect of the present utility model, provide a kind of photovoltaic welding belt high accuracy air knife, comprise air knife body and blast pipe, air knife body comprises air knife air inlet, stores wind chamber and air knife air outlet, blast pipe is inserted by air knife air inlet and stores in wind chamber, the insertion port sealing of blast pipe, and side is provided with a blast pipe air outlet, blast pipe air outlet with store wind chamber and communicate, and blast pipe air outlet direction is contrary with air knife air outlet direction.
Its beneficial effect is: owing to being inserted into the blast pipe stored in wind chamber, end sealing, side is provided with a blast pipe air outlet, and blast pipe air outlet is contrary with air knife air outlet direction, therefore when compressed air is via blast pipe, blast pipe air outlet enters air knife and stores after in wind chamber, wind store in wind chamber through savings then evenly overflow from air knife air outlet, form a stable air curtain, be applied to welding surface, make welding surface pressure even, welding shaping rear surface thickness is consistent, ensure that welding quality, avoid compressed air to enter after in wind chamber and directly go out air knife air outlet, the became uneven of welding is caused because pressure reduction is different.
In some embodiments, this photovoltaic welding belt high accuracy air knife makes material is SUS316.
Its beneficial effect is: because the plasticity of SUS316 stainless steel, toughness, cold denaturation and welding technological properties are good, and resistance to elevated temperatures is good, therefore use SUS316 as the material of this photovoltaic welding belt with high accuracy air knife, greatly strengthen its serviceability.
In some embodiments, air knife air outlet smooth surface.
Its beneficial effect is: because air knife air outlet is through fine grinding, smooth surface, therefore ensure that compressed air from air knife air outlet out time can the spilling of uniform and stable, further ensure welding surface uniform force.
In some embodiments, air knife air inlet lateral wall is provided with external screw thread, can tighten with the nut screw connection on blast pipe.
Its beneficial effect is: air knife air inlet is provided with the external screw thread that can match with the nut on blast pipe, air knife body can be firmly connected with air inlet pipe, and enhance the air-tightness of air knife air inlet, thus ensure that compressed air can be stablized and successfully enter into the storing in wind chamber of air knife body.
In some embodiments, air knife air outlet pressure is less than or equal to 100mbar.
Its beneficial effect is: within the pressure of air knife air outlet is limited in 100mbar, can reduce the impact of wind on welding stability, improve the precision of welding.
Accompanying drawing explanation
Fig. 1 is the structural representation of the photovoltaic welding belt high accuracy air knife of a kind of execution mode of the utility model;
Fig. 2 is the structural representation of the air inlet pipe of the photovoltaic welding belt high accuracy air knife of a kind of execution mode of the utility model;
Fig. 3 is the broken isometric schematic diagram of the air knife body of the photovoltaic welding belt high accuracy air knife of a kind of execution mode of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 ~ Fig. 3 show schematically show the photovoltaic welding belt high accuracy air knife according to a kind of execution mode of the present utility model, comprise air knife body 1 and blast pipe 2, air knife body 1 comprises air knife air inlet 101, stores wind chamber 102 and air knife air outlet 103, blast pipe 2 is inserted by air knife air inlet 101 and stores in wind chamber 102, the insertion port sealing of blast pipe 2, side is provided with a blast pipe air outlet 201, blast pipe air outlet 201 with store wind chamber 102 and communicate, and blast pipe air outlet 201 direction is contrary with air knife air outlet 103 direction.What after so just making compressed air enter blast pipe 2, blast pipe air outlet 201 from the side entered into air knife body 1 stores in wind chamber 102, because the direction of blast pipe air outlet 201 and air knife air outlet 103 is contrary, so wind can not directly go out air knife air outlet 103, butt welding band application plus-pressure, but after storing in wind chamber 102 savings, more evenly overflow from air knife air outlet 103, form the air curtain of a stable and uniform, be applied to welding surface, thus ensure that welding thickness is even.
In order to ensure that blast pipe 2 is firmly connected with air knife body 1, as shown in Figures 1 to 3, the lateral wall of air knife air inlet 101 is provided with external screw thread 104, external screw thread 104 can coordinate with the nut 202 on blast pipe to be tightened, when blast pipe 2 is inserted into storing in wind chamber 102 of air knife body 1, external screw thread 104 cooperation of the nut 202 on blast pipe 2 and air knife air inlet 101 is tightened fixing, blast pipe 2 can firmly be inserted in air knife body 1, compressed air can enter reposefully via blast pipe 2 and store in wind chamber 102, and compressed air can not be leaked outside, ensure that the air-tightness of air knife air inlet 101.
When this photovoltaic welding belt high accuracy air knife works, compressed air enters blast pipe 2 from gas source, what then enter into air knife body 1 by the blast pipe air outlet 201 of blast pipe 2 side stores in wind chamber 102, because blast pipe air outlet 201 is contrary with air knife air outlet 103 direction, so enter store wind chamber 102 compressed air after the accumulation storing wind chamber 102 cavity, finally evenly overflowed by air knife air outlet 103, form the air curtain of a stable and uniform, be applied to welding surface, now, welding surface uniform force, and then ensure that welding thickness is even, substantially increase quality and the serviceability of welding in photovoltaic module of welding.
In order to strengthen the serviceability of this photovoltaic welding belt high accuracy air knife, making material is SUS316.The plasticity of SUS316 stainless steel, toughness, cold denaturation and welding technological properties are good, and resistance to elevated temperatures is good, therefore use SUS316 as the material of this photovoltaic welding belt with high accuracy air knife, greatly strengthen its serviceability.
In order to improve the uniformity of air curtain further, air knife air outlet 103 smooth surface.Air knife air outlet 103, through fine grinding, makes its smooth surface, make compressed air from air knife air outlet 103 out time can the spilling of uniform and stable, further ensure welding surface uniform force, thus improve welding quality.
In order to improve the precision of this photovoltaic welding belt high accuracy air knife, during use, air knife air outlet 103 pressure general control, within 100mbar, decreases the impact of wind on welding stability.
Above-described is only execution modes more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection range of the present utility model.
