Photovoltaic silicon wafer jacking and blowing mechanism

Abstract

The utility model relates to a photovoltaic silicon wafer jacking and blowing mechanism, which is characterized in that a lifting assembly in the photovoltaic silicon wafer jacking and blowing mechanism can jack up a photovoltaic silicon wafer when a photovoltaic basket is in a horizontal state, so that the bottom of the photovoltaic silicon wafer is separated from the photovoltaic basket. And meanwhile, air is sprayed out from the air spraying holes in the cross rod, water drops on the photovoltaic flower basket and the photovoltaic silicon wafer are blown down, and the pre-drying effect is achieved. As water is accumulated at the contact part of the bottom of the photovoltaic silicon wafer and the photovoltaic flower basket, the blowing drying effect is poor, and the pre-drying efficiency can be improved after the bottom of the photovoltaic silicon wafer is separated from the photovoltaic flower basket.

[0038] Embodiment

[0039] This embodiment provides a photovoltaic silicon wafer lifting and blowing mechanism, as Figure 1 shown, including:

[0040] A lifting assembly and a mounting plate 35 that can be lifted driven by the lifting assembly. A plurality of cross bars 36 are provided on the top of the mounting plate 35. Rows of air jet nozzles (usually blowing nitrogen) are provided on the cross bars 36, and the cross bars 36 are hollow and connected to an air supply pipe 37. When the lifting assembly rises, the cross bars 36 can lift the photovoltaic silicon wafers in the photovoltaic flower basket 9.

[0041] In the photovoltaic silicon wafer lifting and blowing mechanism of this embodiment, the lifting assembly can lift the photovoltaic silicon wafers when the photovoltaic flower basket 9 is in a horizontal state, so that the bottom of the photovoltaic silicon wafers is separated from the contact with the photovoltaic flower basket 9 (water will accumulate at the contact part between the bottom of the photovoltaic silicon wafers and the photovoltaic flower basket 9, resulting in a poor blowing and drying effect). At the same time, the air jet nozzles on the cross bars 36 eject gas to blow off the water droplets on the photovoltaic flower basket 9 and the photovoltaic silicon wafers, achieving a pre-drying effect (the blown-off water droplets are collected by the trough 1). It provides a preliminary preparation for further drying and improves the drying efficiency.

[0042] Further, the lifting assembly includes: a fixed plate 31 fixed in the trough 1, a movable plate 32 that can be lifted, a lifting driving member 33 (a cylinder) for driving the lifting of the movable plate 32. The mounting plate 35 is connected to the movable plate 32 through a guide rod 34. The guide rod 34 passes through the fixed plate 31, and the movable plate 32 is arranged parallel to the fixed plate 31. Driving the cross bar 36 to lift through the fixed plate 31, the movable plate 32 and the lifting driving member 33 has the advantages of simple structure and high driving efficiency.

[0043] As Figure 2 described, the photovoltaic silicon wafer lifting and blowing mechanism is arranged in the trough 1.

[0044] Further, the fixed plate 31 is installed at the bottom of the trough 1 through a vertical plate 38, and the vertical plate 38 passes through the movable plate 32. The vertical plate 38 can raise the installation heights of the movable plate 32 and the fixed plate 31, leaving space for water flow.

[0045] Further, a linear bearing 39 is provided on the fixed plate 31, and the guide rod 34 passes through the fixed plate 31 through the linear bearing 39. Setting the linear bearing 39 can reduce the friction force.

[0046] Further, a limit ejector rod 30 is also provided on the surface of the fixed plate 31 close to the movable plate 32. The limit ejector rod 30 can prevent the movable plate 32 from moving excessively.

[0047] Further, there are two sets of the cross bars 36, each set corresponding to one photovoltaic flower basket 9, and each set has four cross bars. The air jet openings on every two cross bars 36 in each set are arranged oppositely, and every two cross bars 36 correspond to a set of photovoltaic wafers. That is to say, there are 8 cross bars 36 in total, which can carry two photovoltaic flower baskets 9. As Figure 3 shown, two cross bars 36 can form a set of photovoltaic wafers and blow the photovoltaic wafers. The photovoltaic flower baskets 9 receive the gas blowing in the way that two sets of photovoltaic wafers are arranged horizontally.

[0048] Further, the plane formed by the top surface of the cross bars 36 corresponding to a set of photovoltaic wafers forms an angle of 3° to 10° with the horizontal plane. For example, the angle is 3°, 5°, 8°, 10°, that is to say, it can make the photovoltaic flower basket 9 tilt slightly to prevent the photovoltaic flower basket 9 from tipping over.

[0049] Further, an air supply joint 14 is also arranged on the outer wall of the trough body 1, and all the air supply pipes 37 are connected to the air supply joint 14. The air supply joint 14 is uniformly connected to an external air supply device, which plays a role in arranging the air supply pipes 37.

[0050] Taking the ideal embodiments according to the present application as the inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this application. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
