Abstract

The present invention discloses a rotary reciprocating photovoltaic silicon wafer cleaning device, which relates to the technical field of photovoltaic silicon wafer cleaning, and includes a cleaning tank. Two sets of conveying components are arranged in the inner cavity of the cleaning tank, and a flushing component is arranged in the inner cavity of the cleaning tank.

When the photovoltaic silicon wafer is placed on the conveying rod for conveying, the photovoltaic silicon wafer will move a certain distance in the direction of the reciprocating mechanism and then move a certain distance in the reverse direction. Due to the setting that the number of teeth of one half gear is more and the number of teeth of the other half gear is less, the distance that the photovoltaic silicon wafer moves forward is greater than the distance that it moves backward. When the photovoltaic silicon wafer is located between two cleaning sponges, the reciprocating movement of the cleaning sponges will clean the photovoltaic silicon wafer, thereby achieving the effect of cleaning the same place of the photovoltaic silicon wafer multiple times.

[0001] The present invention relates to the technical field of photovoltaic silicon wafer cleaning, and particularly to a rotary reciprocating photovoltaic silicon wafer cleaning device. Background Technique

[0002] Photovoltaic silicon wafers are high-purity sheet silicon formed by processes such as slicing, polishing, and cleaning of silicon rods. They are the core raw materials of photovoltaic cells and important semiconductor materials. They have characteristics such as high-efficiency conversion, long life, and low attenuation rate, and are the key materials for manufacturing solar cells.

[0003] In the prior art, cleaning equipment is usually used to clean photovoltaic silicon wafers. Although some existing cleaning equipment is provided with a wiping structure, when the photovoltaic silicon wafer passes through the wiping structure, the wiping structure mostly wipes the same place on the photovoltaic silicon wafer once, which is not convenient for repeatedly wiping the photovoltaic silicon wafer, resulting in a poor cleaning effect on the photovoltaic silicon wafer.

[0004] Combining the above problems, we will find that it is very difficult to avoid the above-mentioned problems simultaneously when the existing cleaning equipment on the market is in use. And even if it can be solved, it needs to be solved by cooperating with external tools, thus unable to achieve the desired effect. Therefore, we propose a rotary reciprocating photovoltaic silicon wafer cleaning device. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1.

[0018] 2. By setting a feeding mechanism, when the conveying rod rotates, the fifth gear rotates synchronously. Using the cooperation between the fifth gear and the toothed plate, the piston block is driven to move in the inner cavity of the installation cylinder, so that the piston block squeezes the cleaning agent into the second long tube through the second one-way valve and discharges it from the liquid outlet hole, so that the cleaning agent is applied to the top and bottom of the photovoltaic silicon wafer, further enhancing the cleaning effect.

A reciprocating mechanism 4 is provided, and the reciprocating mechanism 4 is used to wipe the photovoltaic silicon wafers. A rotating mechanism 5 used in conjunction with the conveying component 2 is provided on one side of the cleaning box 1, and the rotating mechanism 5 is used to drive the conveying rod 201. A feeding mechanism 6 used in conjunction with the reciprocating mechanism 4 is provided on the other side of the cleaning box 1, and the feeding mechanism 6 is used to apply cleaning agent to the surface of the photovoltaic silicon wafers. By setting up a plurality of double-groove transmission shafts 202 and belts 203 for use in conjunction, when one of the conveying rods 201 is rotated, the conveying rods 201 of the same group can be driven to rotate, thereby achieving the effect of conveying the photovoltaic silicon wafers.

[0030] The reciprocating mechanism 4 includes a fixed frame 401 fixedly connected to the inner wall of the cleaning box 1, the number of the fixed frames 401 is two, the inner cavity of the fixed frame 401 is slidably connected to a sliding plate 402, the opposite sides of the two fixed frames 401 are fixedly connected to a cleaning sponge 403, the inner cavity of the fixed frame 401 is slidably connected to two guide rods 404, the opposite sides of the two guide rods 404 are fixedly connected to the sliding plate 402, the opposite sides of the two guide rods 404 penetrate the fixed frame 401 and extend to the inner cavity of the cleaning box 1, the surface of the guide rod 404 is slidably connected to the inner cavity of the cleaning box 1, one end of one of the guide rods 404 is fixedly connected to a first spring 405, and one end of the first spring 405 is fixedly connected to the inner wall of the cleaning box 1 The inner wall of the cleaning box 1 is rotatably connected with a rotating rod 406, and a cam 407 is fixedly connected to the surface of the rotating rod 406. There are two cams 407, and the surface of the cam 407 contacts one end of the guide rod 404. By setting a reciprocating mechanism 4, when the photovoltaic silicon wafer is located between the two cleaning sponges 403, the cam 407 is rotated so that the cam 407 squeezes the guide rod 404, so that the guide rod 404 drives the sliding plate 402 to move in the inner cavity of the fixed frame 401, and then the force deformation of the first spring 405 is used to make the guide rod 404 keep in contact with the cam 407, so that the sliding plate 402 drives the cleaning sponge 403 to reciprocate, thereby achieving the effect of multiple cleaning of the photovoltaic silicon wafer.

The photovoltaic silicon wafer is placed between two adjacent fixing rings, so that the bottom of the photovoltaic silicon wafer is horizontally flush with the top of the lower fixed frame 401. After the photovoltaic silicon wafer is located between two cleaning sponges 403, the rotation of the cam 407 will squeeze the guide rod 404, causing the guide rod 404 to drive the sliding plate 402 to move in the inner cavity of the fixed frame 401. Then, the force deformation of the first spring 405 is used to keep the guide rod 404 in contact with the cam 407, so that the sliding plate 402 drives the cleaning sponge 403 to move reciprocally, achieving the effect of cleaning the photovoltaic silicon wafer multiple times.

[0032] Embodiment 2: Please refer to Figures 1-8 , the present invention provides a technical solution: A rotary reciprocating photovoltaic silicon wafer cleaning device, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0033] The rotation mechanism 5 includes a fixed frame 501 fixedly connected to one side of the cleaning box 1. Two first gears 502 are rotatably connected to the inner cavity of the fixed frame 501. The two first gears 502 are meshed with each other. A semi-gear 503 is fixedly connected to one side of each of the two first gears 502. One end of each of the two conveying rods 201 penetrates to the outside of the cleaning box 1 and is fixedly connected to a second gear 504. A third gear 505 is meshed between the opposite sides of the two second gears 504. One side of the third gear 505 is rotatably connected to the inner cavity of the cleaning box 1. The other side of the third gear 505 is fixedly connected to a fourth gear 506. The fourth gear 506 is located between the two semi-gears 503 and is meshed with the semi-gear 503. A first motor 507 is fixedly connected to one side of the fixed frame 501. The output end of the first motor 507 penetrates to the inner cavity of the fixed frame 501 and is fixedly connected to one side of one of the first gears 502. By setting the rotation mechanism 5, when driving the conveying rod 201, the first motor 507 is started by using an external control switch. The output end of the first motor 507 drives the first gear 502 to rotate, so that one of the first gears 502 drives the semi-gear 503 with more teeth to rotate forward, and the other first gear 502 drives the semi-gear 503 with fewer teeth to rotate backward. As a result, the fourth gear 506 first rotates a certain angle and then rotates backward. Then, through the rotation of the fourth gear 506, the two second gears 504 rotate in the same direction, achieving the effect of driving the conveying rod 201, so that the photovoltaic silicon wafer moves forward a certain distance and then moves backward a certain distance, and the distance that the photovoltaic silicon wafer moves forward is greater than the distance that it moves backward.

[0034] One side of the third gear 505 is fixedly connected to a rotating rod 508. The surface of the rotating rod 508 is rotatably connected to the inner wall of the cleaning tank 1. The surface of the rotating rod 508 is fixedly connected to a first bevel gear 509. One end of the rotating rod 406 is fixedly connected to a second bevel gear 510. The first bevel gear 509 meshes with the second bevel gear 510. By setting the combined use of the rotating rod 508, the first bevel gear 509 and the second bevel gear 510, since the number of teeth of the first bevel gear 509 is greater than that of the second bevel gear 510, when rotating the third gear 505, it will drive the rotating rod 508 to rotate rapidly, thereby causing the first bevel gear 509 to rotate. Since the first bevel gear 509 meshes with the second bevel gear 510, it achieves the effect of driving the second bevel gear 510 to rotate. The rotation of the second bevel gear 510 will drive the rotating rod 406 and the cam 407 to rotate, achieving the effect of driving the cam 407 to rotate.

[0035] The flushing assembly 3 includes a fixed pipe 301 fixedly connected to one side of the cleaning tank 1. A water pump 302 is arranged on one side of the fixed pipe 301. The output end of the water pump 302 is fixedly communicated with the surface of the fixed pipe 301. Two connecting assemblies are arranged in the inner cavity of the cleaning tank 1. The connecting assembly includes two fixed shells 303 fixedly connected to the inner cavity of the cleaning tank 1. Spray heads 304 are fixedly communicated with the opposite sides of the two fixed shells 303. The number of the spray heads 304 is several. A connecting pipe 305 is fixedly communicated with one side of the fixed shell 303. One end of the connecting pipe 305 penetrates to the outside of the cleaning tank 1 and is fixedly communicated with the surface of the fixed pipe 301. By setting the flushing assembly 3, the input end of the water pump 302 is communicated with an external water storage device. The water pump 302 is started to convey the water in the external water storage device into the inner cavity of the fixed pipe 301, and is conveyed into the fixed shell 303 through the connecting pipe 305 and sprayed out from the spray heads 304. The spray heads 304 on the lower fixed shell 303 are located between the two conveying rods 201, so that the spray heads 304 on the lower fixed shell 303 can spray on the bottom of the photovoltaic silicon wafer, thereby realizing the effect of spraying the photovoltaic silicon wafer.

[0036] Four support rods 7 are fixedly connected to the top of the cleaning box 1. The tops of the four support rods 7 are commonly fixedly connected to a support plate 8. A hydraulic telescopic rod 9 is fixedly connected to the top of the support plate 8. The telescopic end of the hydraulic telescopic rod 9 penetrates through the support plate 8 and is fixedly connected to a moving plate 10. A pressing roller 11 that cooperates with the conveying rod 201 is rotatably connected to the inner cavity of the moving plate 10. The number of pressing rollers 11 is several. By setting the cooperation of the support rod 7, the support plate 8, the hydraulic telescopic rod 9 and the pressing roller 11, after the photovoltaic silicon wafer moves to the lower part of the pressing roller 11, the hydraulic telescopic rod 9 is started by using an external control switch, so that the moving plate 10 drives the pressing roller 11 to move downward, so that the photovoltaic silicon wafer is located between the conveying rod 201 and the pressing roller 11, increasing the friction between the photovoltaic silicon wafer and the conveying rod 201. This friction is greater than the friction generated by the cleaning sponge 403 on the photovoltaic silicon wafer, so that the photovoltaic silicon wafer can pass through between the two cleaning sponges 403, avoiding the situation that the photovoltaic silicon wafer cannot move when the cleaning sponge 403 wipes the photovoltaic silicon wafer.

[0037] The specific implementation manner of this embodiment is as follows: When driving the conveying rod 201, the first motor 507 is started by using an external control switch. The output end of the first motor 507 drives the first gear 502 to rotate, so that one of the first gears 502 drives the semi-gear 503 with more teeth to rotate forward, and the other first gear 502 drives the semi-gear 503 with fewer teeth to rotate in the reverse direction. As a result, the fourth gear 506 rotates a certain angle first and then rotates in the reverse direction. Then, through the rotation of the fourth gear 506, the two second gears 504 rotate in the same direction, achieving the effect of driving the conveying rod 201, so that the photovoltaic silicon wafer moves forward a certain distance and then moves backward a certain distance. The distance that the photovoltaic silicon wafer moves forward is greater than the distance that it moves backward. When rotating the third gear 505, it will drive the rotating rod 508 to rotate rapidly, so that the first bevel gear 509 rotates. Since the first bevel gear 509 meshes with the second bevel gear 510, the effect of driving the second bevel gear 510 to rotate is achieved. The rotation of the second bevel gear 510 will drive the rotating rod 406 and the cam 407 to rotate, achieving the effect of driving the cam 407 to rotate, so that the cleaning sponge 403 reciprocates to clean the photovoltaic silicon wafer, thus realizing the effect of cleaning the same place of the photovoltaic silicon wafer multiple times.

The surface of the mounting cylinder 603 is also fixedly communicated with two second one-way valves 609. One end of the second one-way valve 609 is fixedly communicated with a second long pipe 610. One ends of the two second long pipes 610 both penetrate into the inner cavity of the cleaning tank 1 and are respectively communicated with the two fixed frames 401.

The liquid outlet holes 611 are communicated with the mounting cylinder 603 through the fixed frame 401, the second long pipe 610 and the second one-way valve 609. By setting the feeding mechanism 6, the piston block 604 is moved in the inner cavity of the mounting cylinder 603, so that the piston block 604 squeezes the cleaning agent into the second long pipe 610 through the second one-way valve 609 and discharges it from the liquid outlet holes 611, so that the cleaning agent is applied to the top and bottom of the photovoltaic silicon wafer, further increasing the cleaning effect.

One ends of the two L-shaped rods 618 are both fixedly connected to the toothed plate 613. By setting the cooperation of the short rod 612, the toothed plate 613, the fifth gear 614 and the pressing rod 616, when the hydraulic telescopic rod 9 drives the moving plate 10 to move downward, it will drive the pressing block 617 to move downward, so that the pressing block 617 presses the pressing rod 616, causing the pressing rod 616 to move downward. When the pressing rod 616 moves downward, it will drive the L-shaped rod 618 and the toothed plate 613 to move downward, so that the toothed plate 613 meshes with the fifth gear 614. When the double-groove transmission shaft 202 rotates, it will drive the fifth gear 614 to rotate, causing the short rod 612 and the adjusting rod 605 to move reciprocally, so as to achieve the effect of moving the piston block 604. Among them, when the end of the toothed plate 613 and the fifth gear 614 are in a disengaged state, the fifth gear 614 rotates in the reverse direction, which can drive the toothed plate 613 to move in the reverse direction. When the fifth gear 614 rotates in the forward direction, the toothed plate 613 can move to a state of being disengaged from the fifth gear 614, so as to realize the reciprocating movement of the short rod 612, the adjusting rod 605 and the piston block 604.

[0041] The surface of the sliding rod 615 is movably sleeved with a second spring 619. One end of the second spring 619 is fixedly connected to the pressing rod 616. The other end of the second spring 619 is fixedly connected to the top of the cleaning tank 1. The surface of the adjusting rod 605 is movably sleeved with a third spring 620. One end of the third spring 620 is fixedly connected to the mounting cylinder 603. The other end of the third spring 620 is fixedly connected to the surface of the short rod 612. By setting the second spring 619 and the third spring 620, when the pressing block 617 presses the pressing rod 616 downward, the second spring 619 will undergo a force-induced deformation. When the pressing of the pressing rod 616 is cancelled, the force-induced deformation of the second spring 619 will drive the pressing rod 616 to reset. And after the pressing rod 616 is reset, it will drive the toothed plate 613 and the L-shaped rod 618 to move upward, so that the toothed plate 613 is disengaged from the fifth gear 614. At this time, the force-induced deformation of the third spring 620 will drive the short rod 612 and the adjusting rod 605 to reset.

[0042] The inner wall of the installation cylinder 603 is fixedly connected with a sealing ring 621, and the inner wall of the sealing ring 621 is in close contact with the surface of the adjusting rod 605. By providing the sealing ring 621, the sealing ring 621 is in close contact with the adjusting rod 605, thereby increasing the sealing performance between the adjusting rod 605 and the installation cylinder 603 and preventing the cleaning liquid from leaking.

[0043] The specific implementation of this embodiment is as follows: When the hydraulic telescopic rod 9 drives the moving plate 10 to move downward, it will drive the extrusion block 617 to move downward, causing the extrusion block 617 to extrude the pressure rod 616, making the pressure rod 616 move downward. When the pressure rod 616 moves downward, it will drive the L-shaped rod 618 and the toothed plate 613 to move downward, causing the toothed plate 613 to mesh with the fifth gear 614. When the double-groove transmission shaft 202 rotates, it will drive the fifth gear 614 to rotate, causing the short rod 612 and the adjusting rod 605 to move reciprocally, thereby achieving the effect of moving the piston block 604. When the piston block 604 moves in the inner cavity of the installation cylinder 603, the piston block 604 squeezes the cleaning agent into the second long tube 610 through one of the second one-way valves 609, and then transports it to the liquid outlet hole 611 through the fixed frame 401 and discharges it from the liquid outlet hole 611. At this time, the cleaning agent is sucked into the inner cavity of the installation cylinder 603 from the liquid storage tank 606, the first long tube 608, and the first one-way valve 607, realizing the effect of continuously infusing the cleaning sponge 403, so that the cleaning agent is applied to the top and bottom of the photovoltaic silicon wafer, further enhancing the cleaning effect. It should be noted that the first one-way valve 607 for transporting the cleaning agent to the installation cylinder 603 and the second one-way valve 609 for discharging the cleaning agent from the installation cylinder 603 are not on the same vertical line.
