Description

Technical Field

[0001] This application relates to the field of solar photovoltaic technology, and in particular to a dust removal mechanism and processing equipment. Background Technology

[0002] In the photovoltaic cell manufacturing process, the cells are typically handled by using negative pressure chucks to pick up the silicon wafers. Because a large amount of silicon powder is generated on the surface of the cells during the high-temperature process, the chucks become covered in silicon powder during handling, leading to defects such as perforations and microcracks in the silicon wafers.

[0068] Figure 1 A schematic diagram of the overall structure of the dust removal mechanism 1 in one embodiment of this application is shown.

[0069] Please see Figure 1 One embodiment of this application provides a powder removal mechanism 1, including a base 10, a rotating shaft 20, a drive assembly 50, and a powder removal belt 30. At least two rotating shafts 20 are provided, each rotatably mounted on the base 10 about its own central axis. The drive assembly 50 is mounted on the base 10 and is used to drive the rotating shafts 20 to rotate. The powder removal belt 30 is sequentially wound around each rotating shaft 20 to drive each rotating shaft 20 to rotate synchronously. The powder removal belt 30 is sequentially wound around the outer periphery of each rotating shaft 20, and there is no specific order in which the powder removal belt 30 is wound around each rotating shaft 20; it only indicates that the powder removal belt 30 can be driven by any rotating shaft 20. When the surface of the suction cup 2 is attached to the powder removal belt 30, the powder removal belt 30 rotates, simulating a manual wiping action to remove powder. Compared to using an air knife to blow away powder from the surface of the suction cup 2, using the powder removal belt 30 to wipe away powder from the surface of the suction cup 2 is more thorough.

[0070] Example 1

[0071] Figure 2 A top view of the rotating shaft 20 and the dust removal belt 30 is shown in the first embodiment of this application.

[0072] Please see Figure 1 and Figure 2 Optionally, two rotating shafts 20 are provided, with the two rotating shafts 20 spaced apart, and each rotating shaft 20 is rotatably mounted on the base 10 around its own central axis.

[0073] Specifically, the rotating shaft 20 includes a first shaft 21 and a second shaft 22. Both the first shaft 21 and the second shaft 22 are rotatably mounted on the base 10 around their own central axes, and the central axis of the second shaft 22 is parallel to the central axis of the first shaft 21. A powder conveyor belt 30 is wound around the outer periphery of the first shaft 21 and the second shaft 22 and is tensioned to drive the second shaft 22 to rotate synchronously with the first shaft 21.

[0074] Optionally, the drive assembly 50 drives the first shaft 21 to rotate about its own central axis. Since the de-dust belt 30 is tensioned on the outer periphery of the first shaft 21 and the second shaft 22, the de-dust belt 30 drives the second shaft 22 to rotate.

[0075] Optionally, the drive assembly 50 drives the second shaft 22 to rotate about its own central axis. Since the de-dust belt 30 is tensioned on the outer periphery of the first shaft 21 and the second shaft 22, the de-dust belt 30 drives the first shaft 21 to rotate.

[0076] Optionally, the drive assembly 50 drives the first shaft 21 and the second shaft 22 to rotate simultaneously around their own central axis, and the rotational angular velocities of the first shaft 21 and the second shaft 22 are the same.

[0077] Please see Figure 2 Optionally, the powder removal mechanism 1 has a first plane 41, which is tangent to the outer peripheral surfaces of the first shaft 21 and the second shaft 22, and is located on the same side of the first shaft 21 and the second shaft 22. Since the powder removal belt 30 is in motion during operation, a first powder removal section 31 is defined, that is, the portion of the powder removal belt 30 that adheres to the first plane 41 is the first powder removal section 31, which is used to rub the surface of the suction cup 2. When the surface of the suction cup 2 adheres to the first powder removal section 31 of the powder removal belt 30, the powder removal belt 30 rotates, simulating a manual wiping action to remove powder. Compared to using an air knife to blow away powder from the surface of the suction cup 2, using the powder removal belt 30 to wipe away powder from the surface of the suction cup 2 is more thorough.

[0078] Optionally, the powder removed by the powder removal belt 30 may be silicon powder, but is not limited thereto. Understandably, the powder removal belt 30 may also remove other types of powders or mixtures of powders, which are not limited herein.

[0079] Please see Figure 2In this embodiment, the powder removal belt 30 has a centrally symmetrical shape. Therefore, the part of the powder removal belt 30 that is symmetrical with the first powder removal section 31 can also be used to rub the surface of the suction cup 2, which is beneficial to improving the working efficiency of the powder removal mechanism 1.

[0080] Example 2

[0081] Figure 3 A top view of the rotating shaft 20 and the dust removal belt 30 is shown in the second embodiment of this application.

[0082] Please see Figure 1 and Figure 3 Alternatively, the difference between Embodiment 2 and Embodiment 1 is that there are four rotating shafts 20, which are spaced apart, and each rotating shaft 20 is rotatably mounted on the base 10 around its own central axis.

[0083] Specifically, the rotating shaft 20 includes a first shaft 21, a second shaft 22, a third shaft 23, and a fourth shaft 24. The structure and arrangement of the first shaft 21 and the second shaft 22 are the same as in Embodiment 1. The third shaft 23 and the fourth shaft 24 are rotatably mounted on the base 10 around their own central axes, and the central axes of the third shaft 23 and the fourth shaft 24 are parallel to the central axis of the second shaft 22. The powder belt 30 is also wound around the outer periphery of the third shaft 23 and the fourth shaft 24 and tensioned to drive the third shaft 23, the fourth shaft 24, and the first shaft 21 to rotate synchronously.

[0084] Optionally, the drive assembly 50 drives at least one of the first shaft 21, the second shaft 22, the third shaft 23 and the fourth shaft 24 to rotate, thereby driving the dust removal belt 30 to move.

[0085] Please see Figure 3 Optionally, the dust removal mechanism 1 also has a second plane 42, which is tangent to both the outer peripheral surfaces of the third axis 23 and the fourth axis 24. The third axis 23 and the fourth axis 24 are located between the first plane 41 and the second plane 42. Since the dust removal belt 30 is in motion during operation, a second dust removal section 32 is defined, that is, the portion of the dust removal belt 30 that adheres to the second plane 42 is the second dust removal section 32, which is used to rub the surface of the suction cup 2. When the surface of the suction cup 2 adheres to the first dust removal section 31 and the second dust removal section 32 of the dust removal belt 30, the dust removal belt 30 rotates, simulating a manual wiping action to remove the dust.

[0086] Optionally, the second plane 42 is parallel to the first plane 41, so that the first dust removal section 31 and the second dust removal section 32 are arranged in parallel. The third shaft 23 is spaced apart from the second shaft 22, and the fourth shaft 24 is spaced apart from the first shaft 21. The dust removal belt 30 is wrapped around the outer periphery of the first shaft 21, the second shaft 22, the third shaft 23 and the fourth shaft 24, and forms an axisymmetric shape, so that the two parts of the dust removal belt 30 perpendicular to the first dust removal section 31 can also be used to rub the surface of the suction cup 2, which is beneficial to further improve the working efficiency of the dust removal mechanism 1.

[0087] Figure 4 A top view of another arrangement of the rotating shaft 20 in the second embodiment of this application is shown.

[0088] Please see Figure 4 Optionally, the second plane 42 and the first plane 41 form an angle. In this embodiment, the first axis 21, the second axis 22, the third axis 23, and the fourth axis 24 are located within the angle, and the angle is acute. The de-dust belt 30 is wrapped around the outer periphery of the first axis 21, the second axis 22, the third axis 23, and the fourth axis 24, which facilitates the de-dust removal mechanism 1 in removing dust from the suction cups 2 transported from different directions, thereby improving the working flexibility of the de-dust removal mechanism 1.

[0089] Optionally, the first axis 21, the second axis 22, the third axis 23 and the fourth axis 24 are located within the included angle, and the included angle is an obtuse angle.

[0090] Example 3

[0091] Figure 5 A top view of the rotating shaft 20 and the dust removal belt 30 is shown in the third embodiment of this application.

[0092] Please see Figure 1 and Figure 5 Alternatively, the difference between Embodiment 3 and Embodiment 2 is that there are five rotating shafts 20, which are spaced apart, and each rotating shaft 20 is rotatably mounted on the base 10 around its own central axis.

[0093] Specifically, the rotating shaft 20 includes a first shaft 21, a second shaft 22, a third shaft 23, a fourth shaft 24, and a fifth shaft 25. The structure and arrangement of the first shaft 21, second shaft 22, third shaft 23, and fourth shaft 24 are the same as in Embodiment 2. The fifth shaft 25 is rotatably mounted on the base 10 around its own central axis, and the central axis of the fifth shaft 25 is parallel to the central axis of the second shaft 22. The dust removal belt 30 is also wound around the fifth shaft 25 and tensioned to drive the fifth shaft 25 to rotate synchronously with the first shaft 21, second shaft 22, third shaft 23, and fourth shaft 24. The fifth shaft 25 is located within the area enclosed by the first shaft 21, second shaft 22, third shaft 23, and fourth shaft 24, and the dust removal belt 30 is sequentially wound around the first shaft 21, fifth shaft 25, and fourth shaft 24.

[0094] Optionally, the drive assembly 50 drives at least one of the first shaft 21, the second shaft 22, the third shaft 23, the fourth shaft 24 and the fifth shaft 25 to rotate, thereby driving the dust removal belt 30 to move.

[0095] Please see Figure 5 Optionally, the dust removal mechanism 1 also has a third plane 43 and a fourth plane 44. The third plane 43 is tangent to both the outer peripheral surface of the first shaft 21 and the outer peripheral surface of the fifth shaft 25, with the first shaft 21 located on the side of the third plane 43 away from the fifth shaft 25. The fourth plane 44 is tangent to both the outer peripheral surface of the fifth shaft 25 and the outer peripheral surface of the fourth shaft 24, with the fifth shaft 25 located on the side of the fourth plane 44 away from the fourth shaft 24.

[0096] Since the dust removal belt 30 is in motion during operation, a third dust removal section 33 and a fourth dust removal section 34 are defined. Specifically, the portion of the dust removal belt 30 that adheres to the third plane 43 is the third dust removal section 33, and the portion that adheres to the fourth plane 44 is the fourth dust removal section 34. Both the third dust removal section 33 and the fourth dust removal section 34 are used to rub the surface of the suction cup 2. When the surface of the suction cup 2 adheres to the first dust removal section 31 and the second dust removal section 32 of the dust removal belt 30, the dust removal belt 30 rotates, simulating a manual wiping action to remove the dust.

[0097] Optionally, the third plane 43 and the fourth plane 44 are parallel, thereby enabling the powder removal mechanism 1 to remove powder in batches from multiple suction cups 2 inserted between the first plane 41 and the second plane 42, between the second plane 42 and the third plane 43, and between the third plane 43 and the fourth plane 44, which helps to further improve the working efficiency of the powder removal mechanism 1.

[0098] Optionally, the first plane 41, the second plane 42, the third plane 43 and the fourth plane 44 are equally spaced so that the suction cups 2 can be arranged at equal intervals and then inserted into the powder removal mechanism 1 in batches for powder removal, which helps to improve the convenience of powder removal.

[0099] Example 4

[0100] Figure 6 A schematic diagram of the overall structure of the dust removal mechanism 1 in the fourth embodiment of this application is shown. Figure 7 A top view of the dust removal mechanism 1 in the fourth embodiment of this application is shown.

[0101] Please see Figure 6 and Figure 7 Alternatively, the difference between Embodiment 4 and Embodiment 3 is that multiple fifth axes 25 are provided, and each fifth axis 25 is rotatably disposed on the base 10 around its own central axis.

[0102] The length direction of the base 10 is defined as the first direction X, and the width direction of the base 10 is defined as the second direction Y. Multiple fifth axes 25 are spaced apart, alternating left and right along the first direction X. Along the first direction X, the multiple fifth axes 25 are equally spaced. A de-dusting belt 30 is wound in an "S" shape around the outer periphery of each fifth axis 25 and is tensioned to drive each fifth axis 25 to rotate synchronously with the first axis 21. After the de-dusting belt 30 is wound in an "S" shape around the outer periphery of each fifth axis 25, multiple parallel third de-dusting sections 33 and multiple parallel fourth de-dusting sections 34 are formed.

[0103] Optionally, the suction cups 2, arranged at equal intervals, can be divided into odd and even groups for powder removal in two stages. This helps to free up space for installing components such as the rotating shaft 20. At the same time, it ensures that the diameter of the rotating shaft 20 is not too small, which helps to improve the bending strength of the rotating shaft 20.

[0104] Figure 8 yes Figure 7 The enlarged structural diagram of part A shows the cooperative structure of the powder scraper 60 and the powder removal belt 30 in the fourth embodiment of this application.

[0105] Please see Figure 7 and Figure 8 Optionally, the dust removal mechanism 1 may also include a dust scraper 60, which is attached to the third dust removal section 33 to scrape off the powder adhering to the surface of the dust removal belt 30, thereby improving the problem of powder accumulation on the dust removal belt 30 and improving the dust removal effect of the dust removal belt 30.

[0106] Optionally, the dust scraper 60 is attached to the fourth dust removal section 34.

[0107] Optionally, the powder scraper 60 is arranged in a "U" shape. The powder scraper 60 includes a first powder scraping part 61 and a second powder scraping part 62. The first powder scraping part 61 is attached to the third powder removal section 33, and the second powder scraping part 62 is attached to the fourth powder removal section 34.

[0108] Please see Figure 6 and Figure 8 Optionally, the dust removal mechanism 1 also includes a dust collection box 70. The base 10 has a mounting groove 11 opening towards the dust removal belt 30, and the dust collection box 70 is partially disposed within the mounting groove 11. The dust collection box 70 has an opening in a dust collection groove 71 on the side facing the dust removal belt 30. The projections of the third dust removal section 33 and the fourth dust removal section 34 along the central axis of the fifth axis 25 are at least partially located within the dust collection groove 71, so that the dust scraped off the dust removal belt 30 can be collected in the dust collection box 70 for centralized dust processing.

[0109] Figure 9 A schematic diagram of the overall structure of the dust removal mechanism 1 in the fourth embodiment of this application is shown.

[0110] Please see Figure 7 and Figure 9 Optionally, the drive assembly 50 includes a drive member 51, a drive wheel 52, a driven wheel 53, and a timing belt 54. The drive member 51 is disposed on the base 10, and the drive wheel 52 is coaxially fixed to the output shaft of the drive member 51. The driven wheel 53 is disposed on the side of the base 10 away from the first shaft 21, and at least one driven wheel 53 is provided. The driven wheel 53 is coaxially fixed to at least one of the first shaft 21, the second shaft 22, the third shaft 23, the fourth shaft 24, and the fifth shaft 25. The timing belt 54 is wound around the outer periphery of the drive wheel 52 and the driven wheel 53 to drive the driven wheel 53 to rotate synchronously with the drive wheel 52.

[0111] Optionally, the drive assembly 50 also includes an idler pulley 55, which is rotatably mounted on the lower surface of the base 10 and located between the drive pulley 52 and the driven pulley 53. A timing belt 54 is wound around the outer periphery of the drive pulley 52, the idler pulley 55, and the driven pulley 53 and is tensioned. The idler pulley 55 increases the contact area between the timing belt 54 and the drive pulley 52 and the driven pulley 53, mitigating slippage and improving transmission stability.
