Description

Technical Field

[0001] This utility model relates to the field of loading, and in particular to the technical field of loading devices for thin materials such as metal sheets, semiconductor sheets, and solar silicon wafers, specifically a loading device suitable for thin materials. Background Technology

[0002] Silicon wafers are a crucial component of photovoltaic panels, and their production process requires a cleaning step. This cleaning process involves ultrasonic cleaning and drying. Conventional cleaning equipment is inefficient for loading and operating thin materials like solar silicon wafers, leading to a decrease in overall production efficiency.

[0003] Specifically, the storage and transportation of silicon wafers has always been a prominent issue in the semiconductor silicon wafer production process. Currently, the storage and processing of silicon wafers in the production area mainly relies on small silicon wafer loading devices, which have small capacity. The insertion, ejection, and transportation of silicon wafers mainly depend on manual handling by operators. This operation method has disadvantages such as a high rate of human error, the need for dedicated personnel to operate, and the risk of injury. If the loading baskets or equipment are not vertical, twisted, deformed, or unstable, problems such as chips, fragments, and scratches can occur when the wafers are loaded or unloaded.

[0004] Similarly, for thin metal sheets, the stacking of the sheets during cleaning leads to incomplete cleaning, resulting in low efficiency and making batch cleaning impossible. Furthermore, after manual cleaning, fingerprints are easily left on the surface of the thin metal sheets during transfer, further contributing to incomplete cleaning.

[0005] These problems severely restrict the production efficiency of metal sheets, semiconductor silicon wafers, and solar silicon wafers. Furthermore, other non-metallic sheets such as glass substrates, optical materials, flexible materials, plastic films, and special papers also face similar issues, specifically including the following:

[0006] Thin sheets are prone to stacking, slippage, or collision during cleaning, transfer, and drying, resulting in surface scratches, contamination, or breakage. Manual operation makes it difficult to guarantee the accuracy and consistency of each action, leading to fluctuations in yield. At the same time, there are limitations in adapting to thin materials of different sizes, making it difficult to meet diverse loading requirements. In addition, thin materials are prone to deformation, breakage, and chipping during loading, transfer, and even cleaning, affecting product quality. Finally, existing loading devices are insufficient in terms of transfer and positioning, making it difficult to ensure the accurate transfer and positioning of thin materials between different devices.

[0014] According to the preferred scheme, a triangular positioning groove 14 is provided at the tail end 12 away from the material inlet. There are two of them symmetrically arranged on the left and right sides. After the six-axis robot grabs the transfer loading device, it enters the round steel in the large frame of the cleaning machine for positioning.

[0015] According to the preferred embodiment, the tail end 12 is provided with a plurality of through holes 15 to reduce the weight of the material.

[0016] According to the preferred embodiment, the square tube column 2 has a waist-shaped hole 21 along the vertical direction, and the waist-shaped hole 21 has multiple holes and is evenly spaced.

[0018] According to the preferred embodiment, the lines connecting the four square tube columns 2 form an isosceles trapezoidal structure.

[0019] According to the preferred scheme, the partition 3 is set in an L-shape with rounded corners at the bends, and the first and last ends are respectively installed on the square tube columns 2 set at the front and rear.

[0020] The partition 3 includes a horizontal end 31 and a vertical end 32. The horizontal end 31 is set perpendicular to the square tube column 2. The length of the horizontal end 31 is not less than the width difference between the front and rear square tube columns 2 located on the same side.

[0021] According to the preferred design, the partition 3 is made of SUS316 stainless steel round bars bent into shape. It is then welded and fixed to the square tube column in sequence.

[0022] According to the preferred embodiment, buffer pads 4 are installed on the opposite sides of the two sets of square tube columns 2 near the tail end 12 of the stainless steel base plate 1.

[0043] This utility model proposes a loading device suitable for thin materials, which is used to facilitate the transfer and cleaning of thin sheets after loading. This utility model does not limit the type of thin sheet, but the structure of the loading device suitable for thin materials is particularly suitable for metal sheets, semiconductor sheets, solar silicon wafers, glass substrates, optical materials, flexible materials, plastic films, special paper, and other non-metallic sheets.

[0044] In general, the loading device for thin materials proposed in this utility model mainly includes a stainless steel base plate 1, a square tube column 2, and a partition 3. See also... Figure 1 It shows the arrangement of the stainless steel base plate 1, the square tube column 2 and the partition 3.

[0045] As mentioned above, the thin material loading device provided in this embodiment includes a stainless steel base plate 1, a square tube column 2, and a thin material partition 3. A pair of stainless steel base plates 1 are arranged parallel to each other vertically and in the same direction. The stainless steel base plates 1 are configured in a U-shape, with one side of the opening serving as the entrance end for the thin material. By setting two identical upper and lower sections on the stainless steel base plate and adopting a U-shaped structure design, the stability of the base plate is enhanced, giving the loader good support strength and effectively solving the problem of poor stability in the prior art. The stainless steel base plate 1 includes an open end 11 and a tail end. 12. A transfer hook hole 13 is provided on the end of the open end 11 away from the tail end 12 for the six-axis robot to grasp and transfer. A triangular positioning groove 14 is provided on the tail end 12 away from the material inlet. There are two symmetrically arranged on the left and right, and a total of four on the top and bottom. After the loading device is grasped and transferred by the six-axis robot, it is used for positioning on the round steel entering the large frame of the cleaning machine to ensure accurate left and right positioning. The depth of the transfer hook hole 13 and the triangular positioning groove 14 is adapted to the height of the gripper of the six-axis robot. Usually, the large frame inside the cleaning machine is used as a mother basket, and one frame can hold 6 loading devices as a small frame.

[0046] Based on this, four sets of square tube columns 2 are installed between the upper and lower stainless steel base plates 1, forming a quadrilateral structure. The square tube columns 2 and the stainless steel base plates 1 are fixedly connected by bolts to reduce the risk of disintegration caused by loose threads during the transmission of the loading device. Two sets of the square tube columns 2 are installed on the inlet end of the stainless steel base plate 1, and the other two sets are installed on the tail end 12 of the stainless steel base plate 1. The square tube columns 2 have multiple waist-shaped holes 21 along the vertical direction, which are evenly spaced. In this embodiment, the waist-shaped holes serve as both weight-reduction holes and drainage holes. The weight-reduction holes are used to control the overall weight of the loader, while the drainage holes are used to quickly and timely drain the water remaining in the square tube after the overall structure is cleaned in water, which is beneficial for subsequent cleaning and drying processes in the cleaning machine.

[0047] It should be specifically noted that the width of the two square tube columns 2 near the entrance is greater than the width of the two square tube columns 2 behind them. The two sets of square tube columns 2 form a width difference, and the four square tube columns 2 form an isosceles trapezoidal structure. Through the above structure, the width difference between the two sets of square tube columns 2 is equal to the contact distance between the thin material and the loading device when loading. The thin material sheet can be placed flat on these parallel round steel bars, and the contact width between the thin material sheet and the loading device during the loading process is only the aforementioned width difference. The wider opening at the front facilitates the insertion and removal of the thin material sheet, while the narrower width at the rear greatly enhances stability.

[0048] In this preferred embodiment, a buffer pad 4 is installed on the opposite side of the square tube column 2. The buffer pad 4 uses Teflon as the bottom baffle, which has the characteristics of high temperature resistance (<260℃), corrosion resistance, low coefficient of friction and non-hygroscopicity, which is beneficial to the drying effect after cleaning. The buffer pad 4 is made by injection molding process, which has good density uniformity and surface flatness. When the thin material enters the loading device, it is easy to hit the two square tube columns behind it due to the inertia of the sheet. The buffer pad 4 avoids the thin material from deforming, breaking, chipping and other defects, effectively ensuring the integrity and quality of the sheet.

[0049] Next, partitions 3 are installed between a pair of square tube columns 2 arranged along the long side of the stainless steel base plate 1. Multiple partitions 3 are equally spaced and parallel to the stainless steel base plate 1, and a space for loading thin materials is formed between adjacent partitions 3. The partitions 3 are L-shaped with rounded corners at the bends, and the first and last ends are respectively installed on the front and rear square tube columns 2. Specifically, the partition 3 includes a horizontal end 31 and a vertical end 32. The horizontal end 31 is perpendicular to the square tube column 2, and the length of the horizontal end 31 is not less than the width difference between the front and rear square tube columns 2 on the same side. The partitions 3 are made of SUS316 stainless steel round bars bent and welded and fixed to the square tube columns 2 in sequence.

[0050] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
