Description

Technical Field

[0001] The utility model belongs to the technical field of silicon wafer processing, and particularly relates to a carrying basket for silicon wafer cleaning. Background Technique

[0002] In the manufacturing process of silicon wafers, it includes multiple steps such as cutting, cleaning, nickel plating, and lithography. When the silicon wafers are completed with cutting, a special carrying tool is needed to place the silicon wafers and transfer them to the next processing link. Especially in the solar photovoltaic industry, in order to accelerate the cooling and transportation of single crystal silicon rods, a basket-shaped carrying tool is usually adopted. However, the opening of this carrying tool is designed at the top, making it quite inconvenient to load and unload the silicon rods. In addition, in order to facilitate the loading and unloading of the silicon rods and maintain the stability of the carrying tool, its bottom directly contacts the ground, which makes it very laborious to move the entire carrying device.

[0003] A silicon wafer carrying basket for automated production with the patent publication number of CN206992066U includes an outer frame, groove rods, mounting plates, and hook handles. The outer frame is fixedly connected to the mounting plates. There are two mounting plates, which are respectively fixedly connected to both ends of the outer frame. The outer frame and the mounting plates form a closed frame. The mounting plates are fixedly connected to the hook handles. Inside the outer frame on the mounting plates, the groove rods are fixedly connected. Inside the groove rods, there are reinforcing rods. Both ends of the reinforcing rods are in a threaded form. On the outer peripheral surface of the reinforcing rods inside the groove rods, PVDF material is injection-molded. The surface of the groove rods is shark fin teeth. When the above device is performing the silicon wafer cleaning work, it is not convenient to move the silicon wafer carrying basket, and the bottom of the silicon wafer carrying basket contacts the working surface, resulting in poor silicon wafer cleaning effect. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that in the prior art, when the above device is performing the silicon wafer cleaning work, it is not convenient to move the silicon wafer carrying basket, and the bottom of the silicon wafer carrying basket contacts the working surface, resulting in poor silicon wafer cleaning effect.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A carrying basket for silicon wafer cleaning, which is used to carry the silicon wafers after cutting and is hung on the cleaning line to clean the silicon wafers, includes a bracket, a support rod, a hook, a silicon wafer positioning rod, and a fixing member; silicon wafer positioning rods are installed on both sides of the bracket. The silicon wafer positioning rods are rotatably installed inside the vertical rods of the bracket. When the silicon wafer positioning rods rotate to the in-place position, the silicon wafer positioning rods are fixed on the bracket through the fixing member; the support rod is installed at the bottom of the bracket (1), and the hook is installed at the top of the bracket.

[0007] Furthermore, handles are provided at both ends of the bracket, and the handles are fixed to the outside of the bracket by bolts.

[0008] The design of the handles enables the operator to grip and carry the entire carrier basket more conveniently. This is particularly important in situations where the carrier basket needs to be moved frequently, as it reduces the inconvenience during handling and lowers the labor intensity of the operator. By carrying the basket using the handles instead of directly grasping other parts of the carrier basket, accidental contact with the wafers or other precision components can be avoided, thereby reducing the risk of wafer damage caused by improper handling. In addition, the handles provide a more stable gripping point, helping to prevent the basket from slipping during handling. When the carrier basket needs to be placed at a specific location, such as being hung or placed on a cleaning device, the presence of the handles makes the positioning more accurate and convenient. The operator can more easily control the posture of the carrier basket to ensure it is placed or suspended smoothly. Since the handles are fixed by bolts, it means that the handles can be easily disassembled or reinstalled when necessary. This provides convenience for maintenance and replacement, and also allows for the reduction of additional weight or volume when the handles are not required.

[0009] Furthermore, a positioning shaft is provided at the inner bottom of the wafer positioning rod. Threads are provided on the positioning shaft, and the fixing member is sleeved on the positioning shaft. Rotating handles are provided on both sides of the fixing member, and the rotating handles are welded to the fixing member. The fixing member is disassembled or installed by rotating the rotating handles.

[0010] Since the positioning rod can be rotated and adjusted through the positioning shaft and locked in position by the rotating handles on the fixing member, it can quickly adapt to wafers of different sizes. This reduces the preparation time and cost required when replacing wafers of different sizes, improves the flexibility and efficiency of the production line. By rotating the rotating handles on the fixing member, the position of the positioning rod can be precisely fixed at the required position, ensuring that the wafers remain stable throughout the cleaning process and are not easily offset or collided due to external factors, thereby protecting the wafers from damage. The design of the rotating handles enables the operator to conveniently adjust and fix the position of the positioning rod without the need for complex tools or additional assistance. Only a simple rotation is required to complete the adjustment, simplifying the operation process and reducing the operation difficulty. The threaded connection between the fixing member and the positioning shaft, combined with the welded fixation of the rotating handles, ensures the mechanical strength and reliability of the entire system. Such a design can maintain good performance even after multiple uses and adjustments, extending the service life of the carrier basket.

[0011] Furthermore, the wafer positioning rod can rotate between the vertical rods of the bracket in the clockwise direction, and the rotation angle of the wafer positioning rod is 0° - 90°.

[0012] By adjusting the angle of the wafer positioning rod, it can accommodate wafers of different sizes. This means that wafers of various specifications can be processed without changing the carrier basket, reducing downtime and costs caused by changing the carrier device, and improving the flexibility and efficiency of the production line; the wafer positioning rod can be rotated, so that the operator can rotate the positioning rod to make it easier to put the wafer in or out of the carrier basket. This not only simplifies the loading and unloading process, but also reduces the risk of damage to the wafer during loading and unloading; when the wafer positioning rod can be rotated, the wafer can be exposed to the cleaning equipment from different angles to ensure that every side of the wafer can be thoroughly cleaned. Especially for the bottom wafer, the cleaning conditions can be improved by rotating the positioning rod, thereby improving the cleaning quality and consistency. The design of the rotating positioning rod makes the operation more intuitive and simple. The operator can adjust the position of the positioning rod with a simple rotation action without complicated tools or additional steps, reducing the difficulty of operation.

[0013] Furthermore, four hooks are provided in total, and the hooks are welded above the bracket.

[0014] The design of four hooks provides more hanging points, so that the weight can be distributed more evenly when hanging the load basket. This not only prevents the load basket from tilting or flipping during the hanging process, but also ensures that the silicon wafers remain stable during the cleaning process, reducing the damage to the silicon wafers caused by shaking. The hooks are fixed to the crossbar of the bracket by welding. Compared with other connection methods, welding provides stronger mechanical connection strength. This means that the connection between the hook and the bracket is more secure, can withstand higher loads, and is not easy to loosen or fall off due to long-term use or frequent hanging. The four hooks are distributed in different positions of the bracket, giving operators more options when hanging the load basket, and they can choose the most appropriate hanging method according to their needs. In addition, the design of multiple hooks makes it easier to position the load basket on the cleaning equipment, which helps to improve work efficiency.

[0015] Furthermore, two support rods are provided, and the support rods are fixed to the bottom of the bracket by bolts.

[0016] Since the support rods are fixed to the bottom of the bracket by bolts, they can be easily installed or removed. This not only simplifies the initial installation process but also makes it more convenient and efficient when the support rods need to be repaired or replaced. The bolt - fixed method allows the position and height of the support rods to be finely adjusted according to actual needs. This flexibility helps to adapt to different ground conditions or specific process requirements, such as adjusting the height of the support rods to accommodate different cleaning line heights or changes in ground flatness. By being bolt - fixed, the support rods can be firmly installed at the bottom of the bracket, ensuring the stability of the carrying basket when placed. This is particularly important when the carrying basket needs to be placed on the ground for operation, preventing the risk of the carrying basket tilting or tipping over due to unstable support rods.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model rotates and fixes the silicon wafer positioning rod through the positioning shaft and the fixing part, making it easier to load and unload the silicon wafer. By rotating the silicon wafer positioning rod to contact the side of the silicon wafer to carry the silicon wafer, the operation process is simplified and the work efficiency is improved.

[0019] 2. The utility model adds handles at both ends of the bracket, and both the support rod and the hook are fixedly connected, ensuring the stability of the overall structure. At the same time, the design of the handles enables the operator to carry the entire carrying basket more easily, especially in the case of frequent movement, significantly reducing the physical burden of the workers.

[0020] 3. The silicon wafer positioning rod of the utility model can rotate 0 - 90° around the positioning shaft and, in cooperation with the fixing part, can adjust the position according to actual needs, enabling the silicon wafer carrying basket to adapt to more sizes of silicon wafers, better meeting the requirements of different cleaning line equipment, ensuring stability during the cleaning process, reducing the risk of silicon wafer damage. The design of multiple hooks also helps to balance the center of gravity of the carrying basket in the hanging state, ensuring that it will not tilt or flip during the cleaning process.

[0025] The present utility model will be further described in detail below in conjunction with the attached drawings and specific preferred embodiments.

[0026] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "left side", "right side", "upper part", "lower part", etc. is based on the orientation or positional relationship shown in the attached drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not represent the importance of the components, so it cannot be understood as a limitation to the present utility model. The specific dimensions adopted in this embodiment are only for illustrating the technical solution by way of example and do not limit the protection scope of the present utility model.

[0027] Embodiment 1: When cleaning the silicon wafers after cutting, it is usually necessary to place the silicon wafer carrier basket on the working surface for cleaning. The silicon wafers at the bottom of the silicon wafer carrier basket are difficult to clean. Therefore, referring to Figure 1 and Figure 2 , it can be seen that a silicon wafer cleaning carrier basket includes a bracket 1 that constitutes the main body of the device. There are two support rods 2 at the bottom of the bracket 1. A silicon wafer positioning rod 3 is installed inside the vertical rod of the bracket 1. The silicon wafer positioning rod 3 is fixed between the brackets 1 through a fixing member 4. And the silicon wafer positioning rod 3 can rotate between the fixing frames. There are also four hooks 12 installed on the cross bar at the top of the bracket 1. There are handles 11 at both ends of the bracket 1. The handles 11 are fixed to both ends of the bracket 1 by bolts;

[0028] During use, first place a cut silicon wafer neatly on the support rod 2, then rotate the silicon wafer positioning rod 3 to support the side wall of the silicon wafer, and use the fixing member 4 to fix the position of the silicon wafer positioning rod 3. The fixing member 4 is made of aluminum alloy, and the center of the fixing member 4 is a through hole with threads. Thereafter, place the remaining silicon wafers on the silicon wafer positioning rod 3 in sequence. By rotating the two silicon wafer positioning rods 3 inside the bracket 1, the silicon wafer positioning rod 3 can be made to fit or separate from the side of the silicon wafer to be cleaned, facilitating the operator to easily put the silicon wafers in or take them out. Lift the silicon wafer carrier basket using the handle 11 and move it to the working surface of the cleaning equipment. The design of the handle 11 enables the staff to carry it more labor - savingly. Hang the carrier basket on the cleaning line using the hooks 12 at the top. The four hooks 12 provide stable support points to ensure the balance of the carrier basket during the cleaning process. Hang the silicon wafer carrier basket on the cleaning line through the hooks 12. Since the silicon wafer carrier basket is separated from the working surface through the hooks 12, it is possible to clean all aspects of the silicon wafers to be cleaned, improving the cleaning efficiency of the silicon wafers in the silicon wafer carrier basket.

[0029] Embodiment 2: When the existing silicon wafer carrier basket is being cleaned, it can only carry silicon wafers of a fixed size. When the specifications of the silicon wafers change, other suitable silicon wafer carrier baskets need to be replaced, increasing the production cost. Therefore, referring to Figure 1 , Figure 2 and Figure 3 it can be known that the silicon wafer positioning rod 3 is installed on the bracket 1 through the positioning shaft 31. Threads are provided at both ends of the positioning shaft 31, and a thread groove adapted to the positioning shaft 31 is provided inside the fixing member 4. At the same time, a rotating handle 411 is welded on the fixing member 4. When the silicon wafer positioning rod 3 rotates to the side wall of the silicon wafer to be cleaned, the fixing member 4 is driven by rotating the rotating handle 411 to fix the silicon wafer positioning rod 3 on the bracket 1;

[0030] In use, according to the specific size of the silicon wafer to be cleaned, manually rotate the silicon wafer positioning rod 3 to make it closely fit the side wall of the silicon wafer. The silicon wafer positioning rod 3 is installed on the bracket 1 through the positioning shaft 31, and the positioning shaft 31 has threads. The silicon wafer positioning rod 3 can rotate freely within 0 - 90°. Rotate the silicon wafer positioning rod 3 by 45° to fit the side wall of the silicon wafer to be cleaned until the required position is reached. When the silicon wafer positioning rod 3 is adjusted to the appropriate position, use the rotating handle 411 to tighten the fixing member 4. The inside of the fixing member 4 is designed with a thread groove matching the positioning shaft 31. By rotating the rotating handle 411, the fixing member 4 can be driven to screw tightly along the threads on the positioning shaft 31, thereby locking the position of the silicon wafer positioning rod 3 on the bracket 1. The operator can quickly and accurately adjust the position of the silicon wafer positioning rod 3 and fix it through the fixing member 4 to ensure that the silicon wafer will not be damaged due to displacement during the cleaning process. After adjusting the position of the silicon wafer positioning rod 3 and locking it, put the remaining silicon wafers into the carrier basket. The silicon wafer positioning rod 3 can ensure that the silicon wafers are correctly positioned and supported, and can provide good adaptability even if the sizes of the silicon wafers are different. Place the carrier basket with the silicon wafers on the cleaning line and start the cleaning program. The function of the silicon wafer positioning rod 3 is not limited to fixing the silicon wafer, but can also help maintain the stability of the silicon wafer during the cleaning process and avoid displacement caused by water flow impact or other reasons. After the cleaning is completed, take out the silicon wafers from the carrier basket and adjust the position of the silicon wafer positioning rod 3 as needed to adapt to different sizes of silicon wafers in the next batch.

[0031] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
