TECHNICAL FIELD
[0001] The utility model relates to photovoltaic silicon wafer manufacturing technical field especially based on mechanical arm's flower basket to lift drying mechanism. BACKGROUND
[0002] Photovoltaic silicon wafer manufacturing technology mainly includes two kinds of czochralski method and zone melting method, wherein the czochralski method is the mainstream process. In the czochralski method, through feeding, melting, necking growth, shoulder growth, equal diameter growth, tail growth and other steps, high-purity polycrystalline silicon is melted in a single crystal furnace and is drawn to produce a single crystal silicon rod. Subsequently, the single crystal silicon rod is processed into a single crystal silicon wafer through cutting, squaring, grinding, slicing and other processes. Diamond wire multi-wire cutting technology has replaced mortar slicing technology in the single crystal field, with the advantages of fast cutting speed, high silicon wafer quality and low cost.
[0003] In the photovoltaic silicon wafer production process, drying is a key step. First, a mechanical arm is used to lift a flower basket containing silicon wafers from the production line and accurately position it in the drying equipment. Then, according to the characteristics of the silicon wafers, the appropriate drying temperature, time and environmental conditions are set. After starting the drying equipment, hot air uniformly passes through the silicon wafers in the flower basket, ensuring that each piece is fully dried. Throughout the process, parameters such as temperature are continuously monitored and adjusted as necessary. After drying is complete, the mechanical arm lifts the flower basket away and continues with the subsequent process steps.
[0004] In the prior art, the internal bottom end of the flower basket is designed as a flat structure, which causes the silicon wafers loaded inside to easily tilt left and right when the mechanical arm lifts the flower basket. This tilting not only affects the stability of the silicon wafers, but also causes sticking problems during the subsequent drying process, thereby reducing the overall efficiency of drying and the quality of the silicon wafers. Therefore, a flower basket lifting and drying mechanism based on a mechanical arm is proposed to solve the above problems. SUMMARY
[0005] To make up for the above shortcomings, the utility model provides a flower basket lifting and drying mechanism based on a mechanical arm, aiming to improve the problem that in the prior art, the internal bottom end of the flower basket is designed as a flat structure, which causes the silicon wafers loaded inside to easily tilt left and right when the mechanical arm lifts the flower basket.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme:
[0007] The flower basket lifting and drying mechanism based on a mechanical arm includes a solution pool, a liquid medicine circulation pipeline system is fixedly connected to the left side of the solution pool, a mechanical claw arm is arranged inside the solution pool, a loading flower basket is mechanically connected to one side of the mechanical claw arm, and a supporting base is fixedly connected inside the solution pool.
[0008] As a further description of the above technical scheme:
[0009] The outer part of the loading flower basket is arranged on the inner wall of the solution pool, and one side of the loading flower basket is in contact with one side of the supporting base.
[0010] The utility model has the advantages of the following:
[0011] 1. In the utility model, the inclined supporting base is placed in the solution pool, so that the loading flower basket is inclined when placed on it, the silicon wafers loaded inside are inclined in one direction, the situation of sticking silicon wafers is reduced, and the subsequent drying efficiency is improved. In addition, after the mechanical claw arm lifts the loading flower basket, it is first stopped at the top end of the supporting base for a few seconds, and the solution inside the loading flower basket is concentrated on one side and then flows back to the inside of the solution pool by gravity, reducing the solution in the flower basket, especially reducing the water droplets brought into the drying groove by the solution pool in the drying section, reducing the drying time, and improving the drying efficiency.
[0012] 2. In the utility model, the tooth spacing inside the loading flower basket is designed to be 5.44, so that 116 pieces of 210 silicon wafers can be placed inside the loading flower basket. Compared with the existing loading flower basket which can only place 100 pieces of 210 silicon wafers, the carrying capacity of the loading flower basket is improved, and the production capacity is improved.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0019] REFERENCE Figs. 1 to 3This utility model provides an embodiment of a robotic arm-based basket-lifting and drying mechanism, comprising a solution tank 1. The solution tank 1 is used to hold chemical solvents for cleaning silicon wafers. Immersion in the chemical solution can effectively remove impurities, particulate matter, organic matter, and inorganic matter from the surface of the silicon wafers, improving their cleanliness. A chemical solution circulation pipeline system 2 is fixedly connected to the left side of the solution tank 1. This system delivers the chemical solvents into the solution tank 1 to clean the silicon wafers. A robotic claw arm 3 is installed inside the solution tank 1. A loading basket 4 is mechanically connected to one side of the robotic claw arm 3. The loading basket 4 is used to hold silicon wafers. Hooks are mechanically connected to both sides and the middle of the robotic claw arm 3. These hooks allow the loading basket 4 to be lifted, causing the solution on the basket to collect at one end and fall freely back into the process tank. The loading basket 4 is then placed into a drying device for drying.
[0020] The loading basket 4 is externally mounted on the inner wall of the solution tank 1. A support base 5 is fixedly connected inside the solution tank 1. One side of the loading basket 4 contacts one side of the support base 5. The support base 5 is designed with a slope, allowing the loading basket 4 to remain tilted when placed on it, reducing wafer sticking and ensuring proper drying. Simultaneously, after the robotic arm 3 lifts the loading basket 4, it pauses for a few seconds above the support base 5, allowing gravity to concentrate the solution on the loading basket 4 and allow it to fall freely back into the solution tank 1. This reduces the amount of solution carried out of the support base 5 by the loading basket 4, thus conserving chemicals in the solution tank 1. Especially in the drying section, it reduces water droplets brought into the drying chamber from the solution tank 1, shortening drying time and improving drying efficiency. Overall, this saves energy and reduces production costs.
[0021] Working principle: First, the tooth pitch of the loading basket 4 is designed to be 5.44, which allows 116 210 silicon wafers to be placed inside the loading basket 4. Compared with the existing loading basket 4, which can only hold 100 210 silicon wafers, the loading capacity of the loading basket 4 is increased, thus increasing the production capacity.
[0022] Then, the chemical agent used to clean the silicon wafers inside the loading basket 4 is transferred into the solution tank 1 through the chemical circulation pipeline system 2, so that the silicon wafers inside the loading basket 4 are immersed in the chemical agent in the solution tank 1. Subsequently, the robotic gripper arm 3 is lowered so that the hook catches the loading basket 4. After the robotic gripper arm 3 lifts the loading basket 4 from the process tank, it pauses for a few seconds above the support base 5. Gravity allows the solution on the loading basket 4 to concentrate on one side and fall freely back into the solution tank 1. This reduces the amount of solution carried out of the loading basket 4 from the solution in the support base 5, thereby saving chemical agent in the solution tank 1. Especially in the drying section, it reduces water droplets brought into the drying tank from the solution tank 1, which can reduce drying time and improve drying efficiency. Overall, it can save energy and reduce production costs.
[0023] Meanwhile, because the solution pool 1 is equipped with a support base 5, the loading basket 4 is tilted when it is placed on it, causing the silicon wafers loaded inside to tilt in one direction, reducing wafer sticking and thus improving the subsequent drying efficiency.
[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
