Abstract
The utility model discloses a vacuum nozzle which relates to the technical field of solar cell production, in particular to an auxiliary tool for picking and placing a silicon wafer. The vacuum nozzle comprises a straw, wherein a sponge is connected with one end of the straw, and an air hole is formed on a wall at the end connected with the sponge, of the straw. When the vacuum nozzle is in use, the other end of the straw is connected with negative pressure, an operator takes up the straw and presses the air hole with a finger, the negative pressure is generated at the sponge, as the sponge is a porous elastic substance, a generated suction force is uniform, the silicon wafer can be sucked accurately, and no damage is caused to the silicon wafer. When the silicon wafer is not required to be sucked, the finger is removed from the air hole, and the vacuum nozzle is convenient to use and simple in structure.
Description
Technical field
The utility model relates to the technical field that solar battery sheet is produced, and relates in particular to the aid that picks and places silicon chip.
Background technology
Along with the fast development of economic construction, microelectric technique has obtained rapidly development, and in the solar battery sheet manufacturing industry, most important is exactly product percent of pass.Because silicon chip is very thin, very fragile, very accurate, in the process of producing, carry, packing, if directly take silicon chip with hand, easy fragmentation, and silicon chip surface stays finger-marks or dust pollutes, and the suede structure on surface is easily destroyed, affects the performance of silicon chip.For fear of this situation, adopt vacuum WAND, but existing vacuum WAND complex structure adopts the glass head, suction is large, often can inhale simultaneously two or three, has affected use.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of simple in structure, once only inhale the vacuum WAND of a slice silicon chip.
The purpose of this utility model is achieved in that vacuum WAND, comprises suction pipe, and an end of described suction pipe connects sponge, on the tube wall of suction pipe connection sponge one end pore is set.
During use, the other end of suction pipe connects negative pressure, and the operative employee picks up suction pipe and pushes down pore with finger, and the sponge place just produces negative pressure, and owing to sponge is the poroelasticity thing, the suction of generation is even, can hold exactly silicon chip, and to silicon chip without destruction.Finger is removed pore and got final product when not needing to inhale silicon chip, and is easy to use, simple in structure.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, be vacuum WAND, comprise suction pipe 1, an end of suction pipe 1 connects sponge 3, on the tube wall of suction pipe 1 connection sponge 3 one ends pore 2 is set.
Claims (1)
1. vacuum WAND comprises suction pipe, it is characterized in that: an end of described suction pipe connects sponge, on the tube wall of suction pipe connection sponge one end pore is set.
