Description

Technical Field

[0001] This utility model belongs to the field of solar cell sintering technology, and in particular relates to solar cell sintering furnaces. Background Technology

[0002] Solar cells are photoelectric conversion devices that use crystalline silicon as the core material, primarily converting light energy into electrical energy through PN junctions. They are mainly divided into crystalline silicon and amorphous silicon types. Monocrystalline silicon cells have higher efficiency and are black, while polycrystalline silicon cells have lower cost and are blue.

[0003] In the prior art, when solar cells are sintered in a sintering furnace, the internal structure of the sintering furnace generally places the solar cells flat, which results in a slow sintering efficiency on the back side of the solar cells. Therefore, a solar cell sintering furnace is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a solar cell sintering furnace to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a solar cell sintering furnace, comprising a furnace body and a first mounting frame. The first mounting frame is welded inside the furnace body, and a plurality of first heating tubes are fixedly installed inside the first mounting frame. Sliding grooves are provided on both the bottom and top surfaces of the furnace body. The sliding grooves are located on both sides of the first mounting frame. Sliding rods are welded inside the sliding grooves, and sliders are slidably mounted on the periphery of each sliding rod. The periphery of each slider is slidably connected to the inside of the sliding groove. One end of each slider extends to the outside of the sliding groove. A connecting frame is welded between two sliders, and an opening slot is provided at the front end of each of the two connecting frames. A furnace door is installed on one side of the furnace body via a hinge.

[0006] Furthermore, a fixing sleeve is welded to each of the two opposing surfaces inside the two connecting frames, and a telescopic rod is slidably installed inside each of the two fixing sleeves.

[0007] Furthermore, a connecting spring is installed between one end of each of the two telescopic rods and an inner surface of each of the two fixed sleeves.

[0008] Furthermore, the other ends of the two telescopic rods extend to the outside of the fixed sleeve, and a clamping frame is welded to the other ends of the two telescopic rods together.

[0009] Furthermore, the two clamping frames are arranged opposite to each other, and a connecting shaft is installed inside each of the two clamping frames. Rollers are rotatably installed on the circumferential side of each connecting shaft, and the circumferential side of each roller contacts the solar cell.

[0010] Furthermore, a second mounting frame is welded to each of the two opposite surfaces inside the furnace body, and a second heating tube is fixedly installed inside the second mounting frame.

[0011] This utility model has the following beneficial effects: This invention, through its first heating tube, second heating tube, and clamping frame structure, facilitates the sintering of solar cells inside the furnace. First, the solar cells are placed between the clamping frames. The two clamping frames are then opened according to the height of the solar cells. The movement of the clamping frames causes the telescopic rod to slide inside the fixed sleeve, compressing the connecting spring. The reaction force of the compressed connecting spring positions the solar cells between the two clamping frames. The rolling of the rollers facilitates the pushing in of multiple solar cells. Then, the sliding between the slider and the sliding rod pushes the connecting frame into the furnace. Finally, the first and second heating tubes are activated to simultaneously heat and sinter both sides of the solar cells, improving the sintering efficiency of the device.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
