Description

Technical Field

[0002] With the improvement of the production efficiency of photovoltaic production equipment, the number of photovoltaic silicon wafers accommodated in a single photovoltaic flower basket is increasing. For example, Figure 5 As shown, a single photovoltaic flower basket can accommodate two groups of photovoltaic silicon wafers, greatly improving the efficiency of single production. During process cleaning, in order to reduce the width of the tank, the photovoltaic flower basket is placed vertically into the process cleaning tank for cleaning. However, during drying, when the air outlet is at the top, in order to improve the drying effect, it is necessary to lay down the photovoltaic flower basket so that the two groups of photovoltaic silicon wafers are in a horizontal state.

[0003] The Chinese utility model patent document CN219751066U discloses a flower basket flipping and conveying mechanism. In this document, the flower basket can be flipped during conveying, but its flipping is to flip the flower basket from a horizontal side plate state to a vertical state, which does not solve the problem of the position flipping of two groups of photovoltaic silicon wafers, nor does it provide a pre-drying function. Therefore, in the prior art, there is no device that can flip the photovoltaic flower basket from a vertical arrangement to a horizontal arrangement for photovoltaic silicon wafers.

[0050] Embodiment

[0051] This embodiment provides a photovoltaic silicon wafer flipping mechanism ( Figure 1 The mechanism in ) can process two photovoltaic hanging baskets 9 at the same time, and is used to drive the photovoltaic hanging basket 9 to change between the first state and the second state. When the photovoltaic hanging basket 9 is in the first state, the two groups of photovoltaic silicon wafers accommodated in the photovoltaic hanging basket 9 are arranged side by side at an angle less than 10° with the horizontal plane; when the photovoltaic hanging basket 9 is in the second state, the two groups of photovoltaic silicon wafers accommodated in the photovoltaic hanging basket 9 are arranged vertically; as Figure 1 shown, the flipping mechanism 2 includes: a flipping driving member 21, a rotating shaft 22 driven by the flipping driving member 21 to rotate, and an L-shaped support frame 23 provided on the rotating shaft 22 for fixing the photovoltaic hanging basket 9;

[0052] The L-shaped support frame 23 includes a first support plate 231 and a second support plate 232 that are perpendicular to each other. An L-shaped fixing block 233 is provided on the first support plate 231, and the L-shaped fixing block 233 can support the short side of the photovoltaic hanging basket 9.

[0053] In the photovoltaic silicon wafer flipping mechanism of this embodiment, the first support plate 231 and the second support plate 232 respectively support two sides of the photovoltaic hanging basket 9, and the flipping driving member 21 can change the photovoltaic hanging basket 9 from a vertical state to a horizontal state, so that two groups of photovoltaic silicon wafers arranged vertically become two groups of photovoltaic silicon wafers arranged horizontally. It has the advantages of simple structure and easy flipping implementation.

[0054] Furthermore, a flexible layer 234 (made of PTFE material) is provided on the second support plate 232, and the flexible layer 234 contacts the bottom of the long side of the photovoltaic hanging basket 9 to achieve a buffering effect.

[0055] Furthermore, when the L-shaped support frame 23 supports the photovoltaic hanging basket 9 in the first state, the first support plate 231 forms an angle of 3° to 10° with the horizontal plane, such as angles of 3°, 5°, 8°, 10°, that is, the first support plate 231 is slightly inclined to prevent the photovoltaic hanging basket 9 from tipping over. Of course, when a fixing block is provided to prevent the photovoltaic hanging basket 9 from tipping over or the photovoltaic hanging basket 9 itself does not tip over, the angle can also be set to 0°, that is, horizontally arranged.

[0056] Furthermore, the entire photovoltaic silicon wafer flipping mechanism is arranged in the tank body 1, the flipping driving member 21 is arranged outside the side wall of the tank body 1, and the driving shaft of the flipping driving member 21 (motor) passes through the side wall of the tank body 1 and is connected to the rotating shaft 22.

[0057] When the L-shaped support frame 23 supports the photovoltaic hanging basket 9 in the first state, the first support plate 231 is supported by the first support block 15 provided on the bottom of the tank body 1.

[0058] When the L-shaped support frame 23 supports the photovoltaic hanging basket 9 in the second state, the second support plate 232 is supported by the second support block 16 provided on the bottom of the tank body 1.

[0059] Furthermore, the flipping driving member 21 is arranged on the mounting plate 27, and the mounting plate 27 is mounted on the side wall of the tank body 1. Preferably, it is a motor, and of course, it can also be other forms of driving members.

[0060] Furthermore, a triangular stopper 24 is provided on the rotating shaft 22. The stopper 24 has two mutually perpendicular sides, and the two sides are respectively used to limit the excessive rotation of the first support plate 231 and the second support plate 232. That is, when the first support plate 231 and the second support plate 232 rotate beyond the maximum rotation amount, the stopper 24 can abut against the first support plate 231 or the second support plate 232.

[0061] Furthermore, both ends of the rotating shaft 22 are supported by bearings 25, and the rotating shaft 22 is connected to the rotating shaft 22 through a cross-slider coupling 26.

[0062] It should be noted that as Figure 5As shown, the side plate of the photovoltaic hanging basket 9 (with limiting rods arranged on three sides of the photovoltaic hanging basket 9) has a first hook groove 91, a second hook groove 92, and a third hook groove 93. When the photovoltaic hanging basket 9 is vertical, the manipulator hooks the first hook groove 91 and the second hook groove 92 to place the photovoltaic hanging basket 9 on the flipping mechanism 2. After the flipping mechanism 2 flips the photovoltaic hanging basket 9 by a certain angle (the specific value of the angle can generally be selected as 90°), the manipulator then hooks and transports the photovoltaic hanging basket 9 through the second hook groove 92 and the third hook groove 93.

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.
