Description

Technical Field

[0001] The utility model relates to the technical field of solar cell manufacturing equipment, in particular to a boat-beating mechanism and a boat-beating device. Background Art

[0002] During the production of crystalline silicon solar cells, poor contact between the silicon wafers and the boat, as well as between the wafers and the card points, requires tapping the graphite boat to ensure effective contact between the wafers and the boat, and between the wafers and the card points. Specifically, when loading and unloading wafers in the PECVD (Plasma Enhanced Chemical Vapor Deposition) automatic wafer inserter, poor contact between the silicon wafers and the boat blades and card points may occur, necessitating a gentle tapping of the graphite boat. This leverages the silicon wafer's own gravity and the vibrations from tapping the boat to ensure full contact between the wafers and the graphite boat blades and card points, thereby reducing sparks and rework caused by insufficient contact between the wafers and card points or the boat blades, and even wafer fall-off and breakage.

[0003] In the prior art, the method of manually tapping the graphite boat is mainly used for boat tapping. This process does not meet the requirements of automated production and manufacturing, and consumes human resources and labor costs. Therefore, in order to solve this problem, a new type of automatic coating boat tapping device is proposed, such as the Chinese utility model patent (CN213546344U). The driving mechanism drives the roller to move up and down and the vibration generated thereby, so that the boat is tapped over a larger range. However, its boat tapping mechanism is complex and inconvenient to disassemble and assemble. Boat tapping is a high-frequency tapping working method, and the possibility of damage to the boat tapping parts is also relatively high. Therefore, if disassembly and assembly are inconvenient, the boat tapping link will be paused for a long time, affecting the entire battery production process. In addition, its vibration frequency is low, making it difficult to completely make the silicon wafer fall into the card slot. After actual use, there are still silicon wafers that are not fully contacted, and thus these silicon wafers that are not fully contacted will become unqualified products in the next process.

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0043] Existing boat-beating devices primarily use a drive mechanism to drive the roller up and down, generating vibrations that allow them to beat the boat over a wide range. However, the boat-beating mechanism is complex and inconvenient to assemble and disassemble. Because the boat-beating mechanism operates at a high frequency, the boat-beating components are more likely to be damaged. Therefore, inconvenient assembly and disassembly can cause prolonged pauses in the boat-beating process, impacting the entire battery production process. Furthermore, the low vibration frequency makes it difficult to fully position the silicon wafers in the slots. After actual use, some silicon wafers may not be fully contacted, resulting in these wafers becoming defective in the next process step.

[0044] In order to solve the above problems, this embodiment provides a boat-racing mechanism and a boat-racing device.

[0045] Combine Figure 1 and Figure 8This embodiment discloses a boat-beating device. The boat-beating device includes a support frame 30, a conveying mechanism 20 mounted on the support frame 30, and a boat-beating mechanism 10 disposed above the conveying mechanism 20 and mounted on the support frame 30. In this embodiment, there is only one boat-beating mechanism 10. However, multiple boat-beating mechanisms 10 may be provided depending on the length of the conveying mechanism 20 and / or the length of the graphite boat to be beat.

[0046] The support frame 30 includes a first longitudinal frame 301 and a second longitudinal frame 302 disposed opposite each other, and a first transverse frame 303 and a second transverse frame 304 disposed between the first longitudinal frame 301 and the second longitudinal frame 302. The first transverse frame 303 and the second transverse frame 304 are disposed parallel to each other, with the first transverse frame 303 positioned above the second transverse frame 304. The boat flapping mechanism 10 is disposed on the first transverse frame 303. The conveying mechanism 20 is disposed on the second transverse frame 304.

[0047] The conveying mechanism 20 can adopt a belt conveyor. A possible embodiment is that the belt conveyor is mainly composed of a drive motor, rollers, idlers, brackets, etc. Among them, the rollers are located at both ends of the belt conveyor, playing the role of supporting and transmitting power. Among them, the roller at one end of the conveyor is called a drive roller, which enables the belt conveyor to generate traction; the roller at the other end of the conveyor is called an idler roller, which provides support and keeps the conveyor belt moving normally. The bracket supports various parts of the belt conveyor such as the drive motor, rollers and conveyor belt. The drive motor provides power, which drives the drive roller to rotate, thereby driving the conveyor belt to move. The conveyor belt drives the material forward, and the material, i.e., the graphite boat, is transported along the direction of the conveyor belt.

[0048] like Figure 1 As shown, the boat-beating mechanism 10 includes a mounting base 101 , a first driving assembly 40 , a second driving assembly 50 and a boat-beating assembly 60 .

[0049] Combine Figure 3 and Figure 4The first drive assembly 40 includes a first motor 401, a fixed seat 402, a first bearing 403, a retaining ring 404, and a transmission sleeve 405. The first motor 401 is mounted on the mounting base 101. The fixed seat 402 is mounted on the bottom of the mounting base 101. The first bearing 403 is located within the fixed seat 402. A first annular step (not labeled in the figure) is provided at the bottom of the fixed seat 402 to support the outer ring of the first bearing 403. The transmission sleeve 405 is coaxially inserted into the inner ring of the first bearing 403. Furthermore, a second annular step (not labeled in the figure) is provided at the top of the transmission sleeve 405 to abut the inner ring of the first bearing 403. An annular groove is formed on the inner wall of the fixed seat 402. The retaining ring 404 is disposed within the annular groove and coaxially with the first bearing 403 to position and secure the outer ring of the first bearing 403 from the top. The axis of the first bearing 403 is vertical and supports the transmission sleeve 405 in the vertical direction. The first bearing 403 can be a thrust bearing capable of bearing axial forces. The top of the transmission sleeve 405 is coaxially sleeved on the output shaft of the first motor 401, and the inner wall of the transmission sleeve 405 is provided with a first keyway 4051 for setting a key to realize the transmission connection between the transmission sleeve 405 and the output shaft of the first motor 401. The position of the output shaft of the first motor 401 relative to the first keyway 4051 should be provided with a keyway opposite to the first keyway 4051. The bottom of the transmission sleeve 405 is fixedly connected to the second drive assembly 50. The first motor 401 provides power input to the transmission sleeve 405, so that the transmission sleeve 405 drives the second drive assembly 50 to rotate horizontally.

[0050] The second driving assembly 50 includes a first mounting base 501 , a second motor 502 , a first transmission wheel 503 , a second transmission wheel 504 , a transmission belt 505 and a horizontal rotation shaft 506 .

[0051] The bottom of the transmission sleeve 405 is fixedly connected to the first mounting seat 501. The outer wall of the transmission sleeve 405 has a second keyway 4052 along the axial direction and a transverse groove 4053 perpendicular to the axial direction. A key is provided in the second keyway 4052 to achieve a transmission connection between the transmission sleeve 405 and the first mounting seat 501. A shaft retaining plate 407 is provided in the transverse groove 4053. This shaft retaining plate 407 is fixedly connected to the first mounting seat 501 via screws, thereby achieving a fixed connection between the transmission sleeve 405 and the first mounting seat 501.

[0052] The second motor 502 is horizontally fixed to the first mounting base 501. The horizontal shaft 506 is horizontally connected to the first mounting base 501. The second motor 502 is drivingly connected to the first transmission wheel 503. Specifically, the output end of the second motor 502 is connected to the first transmission wheel 503. The second transmission wheel 504 is coaxially fixed to the horizontal shaft 506, and the transmission belt 505 is wound around the first transmission wheel 503 and the second transmission wheel 504. The axes of the first transmission wheel 503 and the second transmission wheel 504 are horizontal. The second motor 502 drives the horizontal shaft 506 to rotate through the first transmission wheel 503, the transmission belt 505, and the second transmission wheel 504 to achieve power input.

[0053] Further, if Figure 3 As shown, a gasket 406 is provided between the first mounting seat 501 and the fixing seat 402, and a third annular step is provided at the bottom of the fixing seat 402, i.e., the side of the fixing seat 402 close to the first mounting seat 501, to limit and fix the top of the gasket 406, and the bottom of the gasket 406 abuts against the top of the first mounting seat 501.

[0054] Further, combined with Figure 3 and Figure 5 The second driving assembly 50 also includes a second mounting seat 507, a second bearing 508, an adjusting screw 509 and a fixing nut 510. The second mounting seat 507 is installed on the side of the first mounting seat 501 away from the boat assembly 60, and the position of the second mounting seat 507 is adjustable. The fixing nut 510 is fixed to the side of the first mounting seat 501. The second mounting seat 507 is installed below the fixing nut 510 so that the upper and lower positions can be adjusted. The adjusting screw 509 passes through the fixing nut 510 from top to bottom and abuts against the second mounting seat 507. The adjusting screw 509 is threadedly engaged with the fixing nut 510. By rotating the adjusting screw 509, the height of the second mounting seat 507 can be adjusted in the vertical direction. In addition, a threaded hole is provided on the side of the first mounting seat 501 away from the boat assembly 60, and a fastening screw 511 adapted to the threaded hole is provided. A vertical slot 512 is provided on one side of the second mounting seat 507. At least one fastening screw 511 passes through the vertical slot 512 and is threadedly connected to the above-mentioned threaded hole to fix the position of the second mounting seat 507 after position adjustment. By adjusting the position of the second mounting seat 507, the tightness of the transmission belt 505 can be adjusted. The tension adjustment of the transmission between the first transmission wheel 503 and the second transmission wheel 504 is achieved. The horizontal rotating shaft 506 is horizontally connected to the second mounting seat 507. A second bearing 508 is provided in the second mounting seat 507, and one end of the horizontal rotating shaft 506 is rotatably engaged with the second bearing 508. In order to withstand the torque of the horizontal rotating shaft 506, the second bearing 508 preferably adopts a bearing group comprising multiple bearings.

[0055] like Figure 6As shown, the boat-slapping assembly 60 includes a third mounting base 601, a clamping member 602, and a boat-slapping member 603. The third mounting base 601 is fixed to the horizontal rotation shaft 506. In this embodiment, a fixing portion 6011 is formed at the bottom of the third mounting base 601, and the fixing portion 6011 is secured to the horizontal rotation shaft 506 by the engagement between the fixing portion 6011 and the horizontal rotation shaft 506. The clamping member 602 is detachably mounted to the third mounting base 601. The boat-slapping member 603 is fixed within the clamping member 602. Specifically, the boat-beating member 603 includes a handle 6032 and a boat-beating portion 6031 located at the end of the handle 6032. The lateral dimension of the area of ​​the boat-beating portion 6031 is larger than the lateral dimension of the handle 6032. The handle 6032 extends into the cavity formed between the clamping member 602 and the third mounting seat 601. The handle 6032 and the clamping member 602 can be further fixed by fastening elements such as bolts. Obviously, the boat-beating member 603 is easy to replace, ensuring the boat-beating efficiency and avoiding affecting the entire production process.

[0056] It should be noted that "detachably mounted" means that the clamping member 602 and the third mounting seat 601 can be fixedly connected by a fastening element, such as a bolt. When it is necessary to separate the clamping member 602 and the third mounting seat 601, the fastening element can be loosened to remove the clamping member 602 from the third mounting seat 601. In addition, to separate the second drive assembly 50, the second drive assembly 50 can be easily disassembled by simply removing the screws connected to the clamping shaft piece 407 and then pulling the clamping shaft piece 407 out of the transverse slot 4053 of the transmission shaft sleeve 405.

[0057] Combine Figure 7 and Figure 8 , the working principle of this embodiment is as follows:

[0058] The conveying mechanism 20 moves the graphite boat to be beaten to a position below the boat beating mechanism 10 .

[0059] According to the specific position of the graphite boat to be beaten, the first motor 401 drives the first mounting seat 501 to swing horizontally, thereby expanding the boat beating range of the boat beating assembly 60 .

[0060] The second motor 502 drives the first transmission wheel 503 to rotate, and the first transmission wheel 503 transmits power to the second transmission wheel 504 through the transmission belt 505. The second transmission wheel 504 drives the horizontal shaft 506 to reciprocate within a certain angle, and the horizontal shaft 506 drives the boat assembly 60 to rotate. Figure 7 As shown, the boat beating part 6031 beats the graphite boat.

[0061] Compared with the existing technology, the boat-beating mechanism provided in this embodiment can achieve a wide range of boat beating while applying uniform force and adjusting the beating amplitude, thus avoiding situations such as excessive local beating force causing damage to the silicon wafer. In addition, the boat-beating device provided by the utility model can automate the boat-beating process during the movement of the graphite boat, reducing labor costs and improving the boat-beating effect.

[0062] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
