[0002] Photovoltaic cells are the basic building blocks of solar cells, which can directly convert sunlight into electrical energy. They are mainly made of semiconductor materials such as silicon. Indium is an important material in the electronics industry, with wide applications in semiconductors, transparent conductive coatings, electronic devices, fluorescent materials, and atomic energy. ITO is the main consumer of indium, accounting for more than 70% of total indium consumption. ITO thin film is an important material, mainly used to improve the light transmittance and conductivity of photovoltaic cells.

[0003] Chinese patent CN210285682U discloses a continuous recycling device for ITO waste targets. This patent discloses a technical solution to improve production efficiency and solves the problem that the existing ITO waste targets and carbon powder are mixed and reacted discontinuously on a furnace-by-furnace basis, resulting in discontinuous recycling of indium and tin, slow recycling speed, high production cost and low efficiency.

[0004] When in use, the device conveys and mixes the target material and carbon powder through the spiral feed pipe, thereby improving production efficiency. However, mixing through the spiral feed pipe alone can easily lead to uneven mixing between the recycled target material and carbon powder, reducing the mixing effect. Therefore, an ITO recycling device for photovoltaic cell production is proposed to solve the above problems. Utility Model Content

Both baffles 19 are in contact with the mixing chamber 11. The bottom surface of the mixing chamber 11 has two positioning holes 21. The top surface of each of the two baffles 19 is fixedly connected to a positioning rod 20 that extends into the positioning hole 21. The top surface of the furnace body 6 has two positioning grooves 16. The bottom surface of the mounting plate 4 is fixedly connected to two positioning plates 15, each with one end extending into the two positioning grooves 16.

[0038] The working principle of the above embodiments is as follows:

[0039] The mixing chamber 11 is pushed into the furnace body 6, where it fits against the baffle 13.

When it is necessary to discharge the mixing chamber 11, the electric push rod 9 is started. The output end of the electric push rod 9 drives the linkage plate 8 to move. Through the sliding connection between the linkage plate 8 and the linkage groove 7, the linkage plate 8 drives the mixing chamber 11 to move, causing the mixing chamber 11 to detach from the furnace body 6.
