Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment, and in particular to a silicon wafer flower basket transplanting and lifting mechanism. Background Technology

[0002] In today's rapidly developing photovoltaic industry, improving the stability of the entire production line and reducing equipment production and maintenance costs have always been constant challenges in the history of photovoltaic development. As larger-size solar cells are increasingly needed by new markets, the overall size of the equipment is gradually increasing, and hardware costs are rising accordingly, creating obstacles to reducing the cost of solar cells.

[0003] During storage and transportation, silicon wafers are typically loaded into baskets. The wafers are carried within the baskets and spaced by toothed strips to facilitate transfer. Therefore, the prerequisite for silicon wafer transportation is the transplanting of the baskets, and the speed of basket transport directly affects the efficiency of wafer transport. The traditional basket transport lifting structure will have an increasingly significant impact on future silicon wafer manufacturing process optimization and is not conducive to adapting to industry market development.

[0004] As the photovoltaic market demands increasing equipment capacity, equipment cycle time is decreasing, and stability requirements are rising. Reducing maintenance time and costs is becoming increasingly important. Existing equipment uses a synchronous belt transfer mechanism to transport the wafers, with a transmission speed of 100mm / s and a total transmission cycle of 8-9 seconds, resulting in low efficiency. Furthermore, the movement of the wafers between belt conveyors generates significant vibration, causing silicon wafer misalignment and potentially leading to wafer breakage. Moreover, synchronous belts are consumables requiring periodic maintenance and replacement, which is cumbersome and necessitates repositioning of the mechanism.

[0005] Therefore, designing a silicon wafer flower basket transplanting and lifting mechanism to improve the efficiency and stability of flower basket transportation is of great significance to the future development of the industry and has good application prospects. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a silicon wafer flower basket transplanting and lifting mechanism, which solves the problem of flower basket transmission on a synchronous belt, reduces the cycle time of the equipment, and improves the efficiency and stability of flower basket transmission.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a silicon wafer flower basket transplanting and lifting mechanism, including a lifting module, a transplanting mechanism, a wafer carrier flower basket, a downward positioning mechanism, a front positioning mechanism for the flower basket, and a side positioning mechanism for the flower basket. The transplanting mechanism is installed on the lifting module and includes a transplanting motor, a transplanting base plate, a slide rail assembly, a middle plate, a transplanting plate, a double-speed synchronous belt, a power wheel, a side plate, a top plate, and a support rod. The transplanting base plate and the top plate are respectively fixedly installed on the bottom and top of the side plate on one side, and connected to the corresponding side plate on the other side by the support rod. The slide rail assembly is set on the transplanting base plate and is connected to the transplanting plate through the middle plate. The transplanting motor drives the power wheel to drive the double-speed synchronous belt to move, thereby driving the middle plate and the transplanting plate to move at double speed. The wafer carrier flower basket is placed on the transplanting plate. The downward positioning mechanism is installed on the top plate above the transplanting mechanism. The front positioning mechanism for the flower basket is set at the front end of the transplanting base plate, and the side positioning mechanism for the flower basket is set on the side of the transplanting base plate.

[0008] Furthermore, the bottom of the transplanting base plate is also provided with reinforcing ribs.

[0009] Furthermore, the pressing and positioning mechanism includes a positioning plate, a pressing cylinder, and a guide shaft, wherein the pressing cylinder drives the positioning plate to move up and down along the guide shaft.

[0010] Furthermore, the flower basket side positioning mechanism includes a positioning cylinder and a mounting base, with the positioning cylinder fixedly mounted on the mounting base.

[0011] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages:

[0012] 1. This utility model utilizes a telescopic mechanism for the rapid transplantation of silicon wafer baskets, increasing the transfer speed of the baskets, reducing the cycle time of the equipment, and decreasing the downtime and frequency of the equipment, thereby increasing the production capacity of the equipment.

[0013] 2. The transplanting method using trays to support silicon wafer baskets ensures stable and vibration-free transport, significantly improving stability. The sliding rail slider facilitates horizontal transport, extending maintenance cycles and enhancing overall equipment stability while reducing maintenance costs. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Example

[0020] refer to Figures 1-3 A silicon wafer transplanting basket lifting mechanism includes a lifting module 1, a transplanting mechanism 2, a wafer carrier basket 3, a downward positioning mechanism 4, a front positioning mechanism 5, and a side positioning mechanism 6. The transplanting mechanism 2 is mounted on the lifting module 1 and includes a transplanting motor 7, a transplanting base plate 9, a slide rail assembly 10, a middle plate 11, a transplanting plate 12, a double-speed synchronous belt 13, a power wheel 14, a side plate 15, a top plate 17, and a support rod 20. The bottom of the transplanting base plate 9 is also provided with reinforcing ribs 8. The transplanting base plate 9 and the top plate 17 are respectively fixedly mounted on one side of the side plate 15. The bottom and top, and the corresponding side plate 15 on the other side are connected by a support rod 20. The slide rail assembly 10 is set on the transplanting base plate 9. The slide rail assembly 10 is connected to the transplanting plate 12 through the middle plate 11. The transplanting motor 7 drives the power wheel 14 to drive the double speed synchronous belt 13 to move, which drives the middle plate 11 and the transplanting plate 12 to move at double speed. The flower basket 3 is placed on the transplanting plate 12. The pressing positioning mechanism 4 is installed on the top plate 17 on the upper part of the transplanting mechanism 2. The flower basket front positioning mechanism 5 is set at the front end of the transplanting base plate 9. The flower basket side positioning mechanism 6 is set on the side of the transplanting base plate 9.

[0021] The pressing and positioning mechanism 4 includes a positioning plate 16, a pressing cylinder 18, and a guide shaft 19. The pressing cylinder 18 drives the positioning plate 16 to move up and down along the guide shaft 19.

[0022] The flower basket side positioning mechanism 6 includes a positioning cylinder 21 and a mounting base 22, with the positioning cylinder 21 fixedly mounted on the mounting base 22.

[0023] During operation, the lifting module 1 raises the entire mechanism to the docking height. The transplanting motor 7 drives the power wheel 14 to drive the synchronous belt 13 to move, which in turn drives the intermediate plate 11 and the transplanting plate 12 to extend at double speed. The lifting module 1 rises to a certain height, so that the transplanting plate 12 lifts the wafer carrier basket 3. The transplanting motor 7 drives in the reverse direction to retract the wafer carrier basket 3 and contact the front positioning mechanism 5 of the basket to complete the front and rear positioning of the basket. The side positioning cylinder 21 extends to complete the side positioning of the wafer carrier basket 3. The pressing cylinder 18 drives the positioning plate 16 to press down and press the wafer carrier basket 3 to complete the positioning. The docking mechanism then begins to lower the silicon wafer.

[0024] After the silicon wafers on the wafer carrier basket 3 are unloaded, the pressing cylinder 18 and the positioning cylinder 21 retract, and the lifting module 1 lowers the entire mechanism to the docking height. The transfer motor 7 drives the power wheel 14 to drive the double-speed synchronous belt 13 to move, which drives the intermediate plate 11 and the transfer plate 12 to extend at double speed. The lifting module 1 lowers to a certain height, so that the wafer carrier basket 3 on the transfer plate 12 is placed on the docking platform. The transfer motor 7 drives in the opposite direction to drive the transfer plate 12 to retract, and the wafer carrier basket completes the loading and unloading of silicon wafers.

[0025] This utility model utilizes a telescopic mechanism for the rapid transplanting of silicon wafer baskets. A synchronous belt connects the transplanting mechanism, enabling it to move at double speed. The transplanting speed is high, with a transmission speed of 200mm / s and a total transmission cycle of 2-3 seconds. Compared to traditional transmission methods, this improves the cycle time by 6-7 seconds, significantly increasing the overall machine cycle time, reducing downtime and downtime frequency, and thus increasing equipment productivity.

[0026] Transplanting is carried out by using trays to support the silicon wafers in baskets. Compared with traditional belt conveyors, the baskets are stable and do not shake during the transmission process, which greatly improves their stability.

[0027] The use of slide rail slider translational motion transmission results in longer maintenance cycles, improved overall equipment stability, and reduced equipment maintenance costs.
