Description

Technical Field This utility model relates to the field of clamping equipment technology, specifically to a flexible silicon cake clamp. Background Technology The photovoltaic industry, which uses silicon as its main raw material, is a typical sunrise industry, booming and thriving. Industrial silicon is currently the fundamental raw material for the development of the photovoltaic industry, mainly used in the production of polysilicon, organosilicon, and aluminum alloy products. In industrial biscuit pressing workshops, silicon cakes are formed by grinding in the grinding workshop and then pressing them through a biscuit pressing machine. Currently, silicon cake collection is mainly done manually, with the cakes being transported and placed in a silicon cake collection cart before being pushed to the next process. The silicon cake collection and pressing process has the following drawbacks: the biscuit pressing machine generates dust during collection, resulting in a harsh working environment for workers; continuous operation during this period leads to high labor intensity for workers; and the silicon cakes are often fragile or already broken. Utility Model Content The purpose of this invention is to provide a silicon cake clamp that is lightweight, occupies little space, and makes flexible contact with the silicon cake. The purpose of this utility model is achieved by the following technical solution: A flexible silicon cake clamp includes a shell, a robotic arm connector, a microprocessor, a pressure sensor, an air pump, and a silicon cake strap. The shell has an open end and a closed end, forming a hollow structure. The robotic arm connector is fixed to the closed end of the shell. The air pump is fixed to the inner wall of the shell. The edge of the silicon cake strap is sealed to the inner wall of the shell to form an air cavity. The air cavity is connected to the air outlet of the air pump. The pressure sensor is fixed to the outer surface of the silicon cake strap. The microprocessor is fixed to the outer end face of the closed end of the shell. The microprocessor is connected to the pressure sensor and the air pump respectively.

[0001] Furthermore, the outer shell has a cylindrical structure, with its inner diameter and height both larger than the silicon cake being clamped.

[0002] Furthermore, a groove is formed on the inner wall of the outer shell, and the air pump is fixed in the groove.

[0003] Furthermore, at least one ring of the silicon cake bundle is fixed radially to the inner wall of the outer casing.

[0004] Furthermore, the silicon cake bundle is made of a soft material.

[0005] Advantages of this utility model: This invention uses an air pump to inflate the space between the silicon cake bundle and the inner wall of the outer shell, making the contact between the silicon cake bundle and the silicon cake flexible and preventing breakage during the clamping process.

Detailed Implementation 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.

[0008] like Figure 1As shown, this embodiment provides the following technical solution: a flexible silicon cake clamp, including a housing 1, a robotic arm connector 2, a microprocessor 3, a pressure sensor 4, an air pump 5, and a silicon cake strap 6. The housing 1 has an open end and a closed hollow structure at the other end. In this embodiment, a cylindrical structure is adopted. To facilitate clamping the silicon cake, the inner diameter and height of the housing 1 are both larger than the silicon cake being clamped. The robotic arm connector 2 is fixed to the closed end of the housing 1, and the housing is fixedly connected to the robotic arm via the robotic arm connector 2 using a snap-fit ​​connection. This connection is convenient for installation and disassembly. When clamping silicon cakes of different sizes, the clamp can be changed to allow the same robotic arm to connect to clamps of different sizes. In this embodiment, the outer shell 1 and the robotic arm connector 2 are integrally molded. The air pump 5 is fixed to the inner wall of the outer shell 1, and the silicon cake strap 6 is fixed to the inner wall of the outer shell 1 by bolts. The edge of the silicon cake strap 6 is sealed to the inner wall of the outer shell 1, forming an air cavity 7 between the silicon cake strap 6 and the inner wall of the outer shell 1. The air cavity 7 is connected to the air outlet of the air pump 5. The air pump 5 injects air into the air cavity 7 to reduce the gap between the silicon cake and the silicon cake strap 6. This embodiment uses a heat-sealing connection, which has a better sealing effect. The silicon cake strap 6 is made of a soft material, such as nylon or polyester or other durable materials. A pressure sensor 4 is fixed to the inner surface of the silicon cake strap 6, with the sensitive surface of the pressure sensor 4 facing the silicon cake contact side. The sensor is encapsulated by hot pressing or waterproof adhesive to ensure that the sensor and the strap are integrated without compromising the airtightness of the air cavity 7. The microprocessor 3 is fixed to the outer end face of the closed end of the outer shell, and the microprocessor 3 is connected to the pressure sensor 4 and the air pump 5 respectively. The microprocessor 3 pre-sets the gas intake of the air pump 5 to set the gripping force. In this embodiment, the microprocessor 3 adopts an industrial-grade embedded microcontroller (STM32F4 series), which has real-time data processing capabilities and multiple PWM / I2C interfaces to receive pressure signals and control the start and stop of the air pump 5.

[0009] A flexible thin-film pressure sensor 4 (Tekscan FlexiForce A201) with a range of 0-100N and a thickness of ≤0.2mm is used. It can be directly attached to the surface of the silicon wafer bundle 6 and outputs pressure values ​​through analog signals. The pressure sensor 4 can be used to measure the pressure changes within the silicon wafer bundle 6 and transmit the feedback to the microcomputer processor 3, so that the microcomputer processor 3 can react and execute the next action.

[0010] This invention uses an air pump 5 to inflate the space between the silicon cake strap 6 and the inner wall of the outer shell 1, making the contact between the silicon cake strap 6 and the silicon cake flexible and preventing breakage during the clamping process. The clamp of this invention has a small space ratio, which can meet the process requirement of small gaps between silicon cakes when stacking silicon cakes in a silicon cake collection vehicle.

[0011] In a preferred embodiment, a groove 11 is formed on the inner wall of the outer casing 1, and the air pump 5 is fixed in the groove 11. In this embodiment, the air pump 5 is a miniature brushless motor air pump (XIAMI Mijia Air Pump), with a maximum air pressure of 10kPa, supporting PWM speed control, integrating overvoltage protection function, and small size that can be embedded in the groove 11 of the outer casing 1. Fixing the air pump 5 in the groove 11 increases the clamping space inside the outer casing, effectively reducing the contact between the silicon cake and the air pump 5 when clamping the silicon cake, thereby avoiding easy damage to the air pump 5.

[0012] Working principle: As the silicon cake moves to the working area of ​​the clamp via the conveyor belt, the robotic arm lowers the clamp to the designated position. At this point, the clamp covers the silicon cake, and the air pump 5 begins to pump air into the air chamber 7 to reduce the gap between the silicon cake and the silicon cake strap 6. When the edge of the silicon cake contacts the outer surface of the silicon cake strap 6, the pressure sensor 4 begins to transmit data to the microprocessor 3. When the pressure value reaches the preset value, the microprocessor 3 reacts and stops the air pump 5 from continuing to pump air into the air chamber 7. At this point, the robotic arm can pick up the silicon cake. When the clamp moves to the designated position of the silicon cake collection vehicle, the air pump 5 stops, and finally the silicon cake is neatly stacked in the silicon cake collection vehicle.

[0013] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
