As the improvement of such scheme, the material of described handle and tube connector is plastics, glass or metal.
Compared with prior art, the utility model silicon chip of solar cell vacuum WAND is provided with depressed part, have and effectively reduce adsorption area, absorption affinity is more uniformly distributed on chip sorption face, thus when adsorbing silicon chip, being partially formed suction trace or forming bulge, even hole can not be formed at silicon chip surface, reduce the fragment rate of last part technology and scrapping of silicon chip, the advantage effectively saved production cost; By being provided with rubber tube between tube connector and suction nib, rubber tube one end is connected with tube connector, the other end is connected with suction nib, because rubber tube has certain shock-absorbing capacity, have and effectively can alleviate the artificial active force to silicon chip, reduce and inhale the frictional force between pen and silicon chip and the collision between silicon chip and quartz boat, reduce the fragment rate of silicon chip and collapse limit rate, improve the rate of finished products of silicon chip in photovoltaic industry diffusing procedure, the advantage effectively saved production cost.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of vacuum WAND of the utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of vacuum WAND of the present utility model, comprises handle 1, tube connector 2 and inhales nib 3, inhales nib 3 for regulating the size of inhaling an internal gas pressure, makes to form negative pressure in suction pen, thus completes the absorption of silicon chip.Handle 1, tube connector 2 and suction nib 3 communicate and form vacuum passage 4, handle 1 is provided with control part 11 and top and is provided with interface 12 for being connected vacuum machine (for illustrating in figure), interface 12 is connected with vacuum passage 4, inhale nib 3 and be provided with depressed part 31, depressed part 31 and the written surface of described suction have difference in height and can form ventilative gap, depressed part 31 has and effectively reduces adsorption area, absorption affinity is more uniformly distributed on chip sorption face, thus when adsorbing silicon chip, can not suction trace be partially formed or form bulge, even form hole at silicon chip surface, reduce the fragment rate of last part technology and scrapping of silicon chip, the advantage effectively saved production cost.Rubber tube 5 is provided with between tube connector 2 and suction nib 3, rubber tube 5 one end is connected with tube connector 2, the other end is connected with suction nib 3, rubber tube 5 is connected with described vacuum passage 4, the length of rubber tube 5 is less than or equal to 1 centimetre, because rubber tube 5 has certain shock-absorbing capacity, have and effectively can alleviate the artificial active force to silicon chip, reduce and inhale the frictional force between pen and silicon chip and the collision between silicon chip and quartz boat, reduce the fragment rate of silicon chip and collapse limit rate, improve the rate of finished products of silicon chip in photovoltaic industry diffusing procedure, the advantage effectively saved production cost.
Further, control part 11 is a through hole be connected with vacuum passage 4, and through hole is circular port, square opening, diamond hole, regular polygon hole or irregular polygon hole.
Further, depressed part 31 is circular depression or rectangular strip depressed part or oval depressions portion or diamond sunk portion or cross depressed part or I-shaped depressed part or regular polygon depressed part or irregular polygon depressed part.
As the improvement of such scheme, the surface of described handle 1 is provided with anti-slip veins 13, and anti-slip veins 13 to be held with a firm grip handle 1 better with being beneficial to producers, prevents workman with inhaling because wet and slippery the causing of hand inhales pen from landing on hand when silicon chip drawn by pen, thus causes die crack.Inhale written 3 surfaces and be provided with pad pasting 32, pad pasting 32 can reduce pollution to silicon chip and damage.The material of handle 1 and tube connector 2 is plastics, glass or metal.
When adopting a kind of vacuum WAND handling of the utility model silicon chip, first the interface 12 of handle 1 is connected vacuum machine, interface 12 is connected with the vacuum passage 4 inhaled in pen, and vacuum machine extracts the gas inhaled in pen in vacuum passage 4 by interface 12.
When silicon chip drawn by needs, workman's void holds the handle 1 inhaling pen, wrist is naturally unsettled, when finger presses control part 11, vacuum passage 4 just forms vacuum extracted the air in it at vacuum machine after, and make the surface of silicon chip form vacuum suction with the surface of the depressed part 31 inhaling nib 3, silicon chip is fixedly adsorbed on the surface of nib 3, thus complete the absorption of silicon chip, be placed into target location; When needs unload lower silicon slice, finger no longer presses control part 11, and air enters vacuum passage 4, and the air pressure in vacuum passage 4 is raised, until equal with the atmospheric pressure of outside, thus makes silicon chip depart from suction pen, thus completes unloading of silicon chip.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection range of the present utility model.
