Description
Technical Field
[0001] This utility model relates to the field of photovoltaic equipment technology, and more specifically, to a novel graphite boat-pulling device. Background Technology
[0002] In the coating process of photovoltaic silicon wafers, graphite boats are used to carry and transport the silicon wafers to the coating mechanism. Existing technology, such as patent publication number CN210325836U, discloses an automated online boat-tapping device for tapping the silicon wafers transported by the boat-wafer transfer mechanism. This automated online boat-tapping device includes a support, a drive unit, and a tapping component. The support is positioned above the boat-wafer transfer mechanism, and the drive unit is connected to the support. The drive unit is configured to drive the support to move towards the boat-wafer transfer mechanism. The tapping component is rotatably connected to the support, and its surface is elastic. The tapping component is configured to tap the silicon wafers. In this device, because the support and the tapping component can move towards the boat-wafer transfer mechanism under the action of the drive unit to tap the silicon wafers inside the graphite boat, the silicon wafers can be completely inserted into the locking points of the graphite boat, thus ensuring the normal progress of subsequent processes and effectively avoiding the phenomenon of silicon wafer fragmentation in subsequent processes.
[0003] However, the following problems still exist: there is a lack of direct and effective connection structure between the fixing device and the transmission device of the boat beater. When the vibration generated by the vibrator is transmitted to the boat beater roller through the fixing plate and fixing bolts, the vibration transmission effect is poor due to the gap between the fixing bolts and the fixing plate. The vibration cannot be perfectly transmitted to the boat beater roller, resulting in poor boat beater effect. Consequently, it is difficult for the silicon wafer to fall completely into the jamming point of the graphite boat, which easily leads to wafer warping. This increases the risk of silicon wafer fragmentation in subsequent processes and affects the coating efficiency and yield.
[0004] Therefore, a new type of graphite boat beater is needed to solve the problem of poor vibration transmission in existing boat beaters. Utility Model Content
[0005] The purpose of this invention is to provide a novel graphite boat beater. By optimizing the connection structure between the beater roller and the fixed plate, a direct and effective vibration transmission path is constructed, solving the problem of low vibration transmission efficiency in the prior art. This ensures that the silicon wafer can fall accurately and stably into the graphite boat's locking point, thereby significantly reducing silicon wafer fragments and improving the overall efficiency and yield of the coating process.
[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a novel graphite boat beater, comprising: a beating roller for beating silicon wafers; a first fixed plate connected to a driving component, the driving component driving the first fixed plate to move; a second fixed plate located above the first fixed plate, the two ends of the beating roller being fixedly connected to the first fixed plate by bolts, the bolts penetrating the first fixed plate; and a connecting member connected between the first fixed plate and the second fixed plate, used to transmit vibration and limit the movement of the second fixed plate.
[0007] According to the present invention, a novel graphite boat-pulling device is provided, wherein the connecting member includes an intermediate shaft and nuts respectively disposed at both ends of the intermediate shaft, the intermediate shaft passes through the first fixing plate and the second fixing plate, and the nuts are used to connect and fix the first fixing plate and the second fixing plate.
[0008] According to the present invention, a novel graphite boat-pulling device is provided, which further includes a pad block disposed between the first fixing plate and the second fixing plate to prevent the first fixing plate and the second fixing plate from directly contacting each other.
[0009] According to the present invention, a novel graphite boat-pulling device is provided, wherein the driving component is a cylinder, and the first fixing plate is fixedly connected to the piston rod of the cylinder.
[0010] According to the present invention, a novel graphite boat beater is provided, wherein a spring is provided between the beater roller and the first fixed plate, and the spring is sleeved outside the bolt to provide cushioning when the beater roller contacts the graphite boat.
[0011] According to the present invention, a novel graphite boat-beating device is provided, which further includes a vibrator. The vibrator is mounted on the second fixed plate and is used to generate vibration and transmit the vibration to the boat-beating roller through the connecting member.
[0012] The present invention discloses the following technical effects:
[0013] This invention incorporates a connector to alter the connection between the wave-beating roller and the fixed plate. During wave-beating operation, the driving component presses down the first fixed plate, causing the wave-beating roller to contact the graphite boat and experience an upward force. The wave-beating roller then drives the second fixed plate to move upward via bolts. The connector limits the upward movement of the second fixed plate while effectively transmitting vibrations to the wave-beating roller through the second fixed plate and the connector. This enhances the wave-beating effect, ensures the silicon wafer accurately falls into the graphite boat's locking point, reduces wafer warping and fragmentation, and improves the efficiency and yield of silicon wafer coating.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1 to 2 As shown, this utility model provides a novel graphite boat beater, comprising: a beater roller 1 for beating silicon wafers; a first fixed plate 2 connected to a driving component, the driving component driving the first fixed plate 2 to move, the two ends of the beater roller 1 being connected to the first fixed plate 2 by bolts 8; a second fixed plate 3 located above the first fixed plate 2; and a connector connecting the first fixed plate 2 and the second fixed plate 3 for transmitting vibration and limiting the movement of the second fixed plate 3.
[0021] The boat beater directly contacts and beats the silicon wafer inside the graphite boat. Through vibration, the silicon wafer falls accurately into the locking point. Bolts 8 are fixedly connected to both ends of the boat beater. The bolts 8 extend upward through the first fixed plate 2 and are fixedly connected to the second fixed plate 3, so that the boat beater roller 1 is directly fixedly connected to the second fixed plate 3. Its surface can be made of elastic material. In this embodiment, Oxford rod is used, but it is not limited to Oxford rod, to provide cushioning during beating and avoid damage to the silicon wafer.
[0022] The first fixed plate 2 is located below the device and is connected to the driving component, which is a cylinder. The first fixed plate 2 and the piston rod of the cylinder are fixedly connected by bolts. Under the action of the driving component, the boat roller 1 is driven to move up and down. The bolt 8 is fitted with a spring 7 to form a buffer structure. When the boat roller 1 contacts the graphite boat, the spring 7 is squeezed and compressed to provide buffer force, avoid the boat roller 1 from making a hard impact on the graphite boat, and protect the graphite boat pages.
[0023] The second fixed plate 3, located above and parallel to the first fixed plate 2, serves as an intermediate carrier for vibration transmission, receiving and transmitting the vibrations generated by the vibrator 9. The vibrator 9 is mounted on the second fixed plate 3, generating regular vibrations. These vibrations are directly transmitted to the boat-beating roller 1 through the second fixed plate 3, enhancing the boat-beating effect. In this embodiment, the vibrator 9 is an electromagnetic vibrator of model GT08.
[0024] The connector includes an intermediate shaft 5 and nuts 6 at both ends of the intermediate shaft 5. The intermediate shaft 5 passes vertically through the first fixed plate 2 and the second fixed plate 3. By setting the intermediate shaft 5 and nuts 6, the first fixed plate 2 and the second fixed plate 3 can be rigidly connected, eliminating the gap in the prior art and constructing a direct vibration transmission path. At the same time, it limits the movement of the second fixed plate 3, ensuring the displacement accuracy of the boat roller 1 when it contacts the graphite boat and avoiding excessive compression.
[0025] A pad 4 is installed between the first fixed plate 2 and the second fixed plate 3. The pad 4 is distributed around the intermediate shaft 5 to prevent the two fixed plates from contacting directly, reduce friction and wear, and at the same time provide reasonable space for the spring 7 to compress.
[0026] like Figure 1 As shown, when not compressed, the first fixing plate 2 and the second fixing plate 3 are in a static state. The second fixing plate 3, under the influence of gravity, has a downward force that causes it to adhere to the first fixing plate 2, but they do not contact each other because a pad 4 is provided between the first fixing plate 2 and the second fixing plate 3; Figure 2 As shown, during extrusion, the cylinder drives the first fixed plate 2 to move downward, while the second fixed plate 3 is still affected by gravity and moves downward. The boat roller 1 contacts the graphite boat and is subjected to an upward force, and the bolt 8 pushes the second fixed plate 3 upward.
[0027] Working principle: In the initial state, the cylinder piston is in the retracted state, the first fixed plate 2 drives the boat roller 1 to the upper standby position, and the spring 7 is in the freely extended state, as shown below. Figure 1As shown; when the boat-beating action is initiated, the cylinder piston rod extends, pushing the first fixed plate 2 downward, and the boat-beating roller 1 moves downward accordingly, moving towards the graphite boat being conveyed. When the boat-beating roller 1 contacts the surface of the graphite boat, it receives an upward reaction force, pushing the boat-beating roller 1 upward through the bolt 8, compressing the spring 7, and simultaneously pushing the second fixed plate 3 upward. The vibrator 9 is activated synchronously, and the vibration is directly transmitted to the boat-beating roller 1 through the second fixed plate 3 and indirectly transmitted to the boat-beating roller 1 through the nut 6, intermediate shaft 5, and nut 6, causing the boat-beating roller 1 to generate high-frequency vibration, strengthening the vibration effect, and causing the silicon wafer to fall into the graphite boat's locking point.
