DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0023] See also Figure 1-Figure 5 The figure shows a photovoltaic cell wet process tank drying tank, which includes a box body 1, a drying component and a moving guide component. A filter plate 2 is fixed inside the box body 1. The drying component is installed on the opposite sides of the inside of the box body 1 to dry the silicon wafers placed on the flower basket inside the box body 1. The filter plates 2 are installed on the opposite sides of the outside of the box body 1 to guide the movement of the drying component.

[0024] See also Figure 1-Figure 4 The drying component shown in the figure includes vertical pipes 3 arranged on opposite sides of the inner wall of the box body 1, and nozzles 4 are fixedly provided at equal distances on one side wall of the vertical pipe 3. A hose 5 is connected to one end of the vertical pipe 3, and one side of the hose 5 is connected to one end of a high-pressure fan 6. A connecting pipe is provided at the other end of the high-pressure fan 6, and one end of the connecting pipe is connected to one side of a heating box 7. A heating network 8 is provided inside the heating box 7, and one side of the heating box 7 is connected to one side of the box body 1 through an air inlet pipe 9.

[0025] See also Figure 1 , Figure 3-Figure 5 The movable guide assembly shown in the figure includes a first guide rail 10 and a second guide rail 11 arranged on opposite sides of the box body 1, and the first guide rail 10 and the second guide rail 11 are both provided with a convex rail section 12 and a flat rail section 13, and the convex rail sections 12 and the flat rail sections 13 on the first guide rail 10 and the second guide rail 11 are alternately staggered;

[0026] See also Figure 1 , Figure 3-Figure 5 The mobile guide assembly shown in the figure also includes a mobile wheel 14, which is slidably arranged inside the first guide rail 10 and the second guide rail 11. A column 15 is fixedly arranged at one end of the mobile wheel 14, and a U-shaped plate 16 is fixedly arranged at the end of the column 15 away from the mobile wheel 14. One end of the U-shaped plate 16 is fixedly connected to the outer wall of the vertical pipe 3 through a connecting rod 17. A guide groove 18 is opened on the U-shaped plate 16, and a guide block 19 is slidably arranged inside the guide groove 18. A mobile block 20 is fixedly arranged at one end of the guide block 19. The mobile block 20 is slidably arranged inside the slide rail 21, and one side of the slide rail 21 is fixedly arranged on the outer wall of the box body 1. A reciprocating screw 22 is arranged inside the slide rail 21, and the mobile block 20 is threadedly sleeved on the reciprocating screw 22, and one end of the reciprocating screw 22 is connected to the driving assembly.

[0027] When the silicon wafers are dried in the trough-type drying box: first, the silicon wafers placed on the flower basket are placed on the filter plate 2 inside the box body 1, and the filter plate 2 can support the flower basket. Then, the driving assembly is started, and the driving assembly can drive the reciprocating screws 22 on both sides of the box body 1 to rotate synchronously. The rotation of the reciprocating screws 22 can make the moving block 20 reciprocate inside the slide rail 21. During the movement of the moving block 20, the guide block 19 on one side can be driven to reciprocate synchronously. The guide block 19 is slidably connected to the U-shaped plate 16. When the guide block 19 moves, it can push the U-shaped plate 16, so that the U-shaped plate 16 moves synchronously with the moving block 20 in the horizontal direction. Since one end of the U-shaped plate 16 is fixedly connected to one side of the vertical pipe 3 through the connecting rod 17, the vertical pipe 3 can be driven to reciprocate in the horizontal direction.

[0028] When the vertical pipe 3 reciprocates in the horizontal direction, the high-pressure fan 6 is started at this time. When the high-pressure fan 6 is started, the hot air heated by the heating network 8 inside the heating box 7 can be drawn into the hose 5, and then transported to the vertical pipe 3 by the hose 5, and finally sprayed out by the nozzle 4 on the side wall of the vertical pipe 3, so as to achieve the effect of blowing and drying the silicon wafers placed on the flower basket inside the box body 1; when the vertical pipes 3 on both sides of the box body 1 are installed, the vertical pipes 3 are respectively located at different ends of the inner wall of the box body 1 on both sides, so that the moving blocks 20 on both sides can be driven to move toward each other when the reciprocating screw 22 rotates, so that the vertical pipes 3 on both sides of the box body 1 move toward each other, which can simultaneously dry both sides of the silicon wafers, thereby improving the drying efficiency of the silicon wafers.

[0029] When the U-shaped plate 16 moves outside the box body 1, the moving wheel 14 at one end of the column 15 can slide inside the first guide rail 10 and the second guide rail 11 respectively. The first guide rail 10 and the second guide rail 11 are alternately provided with convex rail sections 12 and flat rail sections 13, and the convex rail sections 12 and flat rail sections 13 on the first guide rail 10 are alternately staggered with the convex rail sections 12 and flat rail sections 13 on the second guide rail 11. It can be achieved that when the moving wheel 14 moves to the convex rail section 12 on the first guide rail 10, the moving wheel 14 on the other side moves to the flat rail section 13 on the second guide rail 11, and when the moving wheel 14 moves to the flat rail section 13 on the first guide rail 10, the moving wheel 14 on the other side moves to The convex rail section 12 on the second guide rail 11 can realize the moving wheels 14 on both sides of the box body 1 to alternately rise and fall in the first and second guide rails. While the moving wheels 14 are rising and falling, they can drive the U-shaped plate 16 to rise and fall through the columns 15, and the U-shaped plate 16 can be lifted and lowered by the guide groove 18 on the guide block 19, so that the U-shaped plate 16 can move in the horizontal direction and rise and fall in the vertical direction at the same time, and the vertical pipe 3 on one side can be driven to move horizontally and rise and fall at the same time, so that the nozzle 4 on one side of the vertical pipe 3 can alternately dry different positions of the silicon wafers on the flower basket; the drying efficiency of the silicon wafers can be improved.

[0030] When the moving wheels on both sides of the box body 1 alternately rise and fall on the first and second guide rails, the vertical pipes 3 on both sides are driven to rise and fall, so that the nozzles 4 on one side of the vertical pipes 3 are alternately replaced at one side of the silicon wafer on the flower basket, and the nozzles 4 on the two vertical pipes 3 are alternately placed to avoid the hot air sprayed by the nozzles 4 on both sides causing convection to affect the drying of the retained liquid between the silicon wafers. The alternate arrangement of the nozzles can achieve the effect of drying and blowing the retained liquid between the two adjacent silicon wafers on the flower basket, and flow down from the other side opposite to the nozzles 4 into the interior of the box body 1 to achieve separation between adjacent silicon wafers, and then flow into the bottom of the lower box body 1 through the filter plate 2 inside the box body 1, and be discharged from the drain pipe at the bottom of the box body 1. The nozzles 4 are reciprocally driven by the mobile guide assembly to move back and forth on both sides of the box body 1, thereby increasing the efficiency of drying the retained liquid between the silicon wafers and reducing the patch between the two adjacent silicon wafers, effectively improving the efficiency of silicon wafer drying and improving the drying quality of the silicon wafers.

[0031] The heating box 7 is connected to one side of the box body 1 through the air inlet pipe 9, which can recycle the hot air ejected from the box body 1, reduce the energy loss caused by the heating network heating the cold air with a large temperature difference, and effectively save energy.

[0033] See also Figure 1-Figure 3 The driving assembly shown in the figure includes a first gear 23 fixed to one end of a reciprocating screw 22, a second gear 24 is provided on one side of the first gear 23, the first gear 23 and the second gear 24 are meshed and connected via a gear chain 25, and one side of the second gear 24 is connected to the output end of a motor 26;

[0034] See also Figure 2 In the figure, a water-absorbing cotton plate 27 is fixedly provided inside the heating box 7 and on one side of the heating net 8 at an equal distance.

[0035] In this embodiment, the driving component can synchronously drive the reciprocating screws 22 on both sides of the box body 1, which can reduce the use of driving equipment, effectively reduce cost investment, and increase the convenience of rotating the reciprocating screw 22. The motor 26 in the driving component is started, and the motor 26 is started to drive the second gear 24 at the output end to rotate. The rotation of the second gear 24 can drive the first gear 23 to rotate through the engagement of the tooth chain 25. The first gear 23 is fixedly installed at the end of the reciprocating screw 22, so that the rotation of the first gear 23 can drive the rotation of the reciprocating screw 22, thereby increasing the convenience of rotating the reciprocating screw 22. An inclined water-absorbing cotton plate 27 is fixedly provided inside the heating box 7, which can dehumidify the hot air sucked into the heating box 7 from the inside of the box body 1, reduce the moisture in the hot air, improve the dryness of the hot air, and improve the efficiency of hot air in drying the silicon wafers between the patches. Example 3

[0036] See also Figure 1-Figure 5 This embodiment further illustrates other embodiments.

[0039] In this embodiment, a spring 28 is fixedly provided on one side above the guide block 19, which can push the U-shaped plate 16. When the U-shaped plate 16 moves upward, it can push and pull the spring 28 above the guide block 19, so that the spring 28 is stretched and elastic potential energy is stored. When the moving wheel 14 moves to the flat rail section 13, the U-shaped plate 16 loses the stretching of the spring 28 and descends under the pull of the spring 28 and the action of gravity, causing the U-shaped plate 16 to descend, thereby increasing the convenience of the U-shaped plate 16 to descend; a support plate is provided below the motor 26, which can support the motor 26, thereby avoiding the motor 26 from being placed in the air, thereby increasing the safety of the placement and use of the motor 26.
