[0002] A sintering furnace is a special equipment that enables powder compacts to obtain the required physical and mechanical properties and microstructures through sintering. The sintering furnace is used to dry the slurry on the silicon wafer, remove the organic components in the slurry, and complete the sintering of the aluminum back field and grid lines.

[0003] When the existing sintering furnace performs sintering, it is necessary to perform high-temperature sintering on the powder compact, and at the same time, a rapid cooling device is used, which can quickly cool the sintered parts to the furnace outlet temperature without oxidation. However, the following problems still exist in the process of using the existing sintering equipment:

[0004] The existing compacts are processed by a high-temperature device and a cooling device in sequence. Due to the limited use ranges of the high-temperature device and the cooling device, it is impossible to perform high-temperature and cooling treatments on the compacts comprehensively and uniformly, which affects the quality of the compacts. Therefore, it is very necessary to involve a sintering device for solving the ignition of combustible gas-assisted sintering in the field of existing sintering equipment. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology, the existing compacts are processed by a high-temperature device and a cooling device in sequence. Due to the limited use ranges of the high-temperature device and the cooling device, it is impossible to perform high-temperature and cooling treatments on the compacts comprehensively and uniformly, which affects the quality of the compacts. The utility model provides a sintering device for solving the ignition of combustible gas-assisted sintering.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a sintering device for solving the ignition of combustible gas-assisted sintering, including a sintering furnace, on which a furnace cavity is provided.

The top of the sintering furnace is fixedly equipped with an operating motor, and the output end of the operating motor is fixedly equipped with a rotating rod. The rotating rod movably penetrates into the furnace cavity, and the bottom of the rotating rod is fixedly equipped with a sector gear. The sector gear is located between the two traction racks, and the sector gear is only engaged with one of the traction racks by tooth patterns.

[0007] Preferably, a connecting block is fixedly equipped on the side surface of the elliptical frame. One end of the connecting block is provided with a slot, and the symmetric side surfaces of the connecting block are provided with card holes, and the card holes communicate with the slot.

[0008] Preferably, an assembly block is movably assembled on the slot, and a placement box is fixedly assembled at one end of the assembly block. The placement box is located on one side of the connection block, and operation cavities are symmetrically arranged inside the assembly block.

[0009] Preferably, telescopic springs are fixedly assembled on the operation cavities. Limit blocks are fixedly assembled at one ends of the telescopic springs, and telescopic buttons are fixedly assembled on the limit blocks. The telescopic buttons movably penetrate through the assembly block, and the telescopic buttons are correspondingly clamped with the card holes.

[0011] Preferably, an igniter is fixedly assembled on the duct, and the igniter is close to one end of the duct.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By pressing the telescopic button of the present utility model, the limit block drives the telescopic spring to contract in the operation cavity, so that the assembly block is separated from the slot on the connection block, which facilitates the disassembly and assembly of the placement box. Place the green compact in the placement box, start the operation motor, so that the rotating rod drives the sector gear to rotate. The sector gear is only engaged with one of the traction racks by tooth patterns, so that the elliptical frame reciprocates on the slide bar through the sliding block. The duct sprays combustible gas, and high-temperature flame is generated under the action of the igniter to perform high-temperature treatment on the green compact on the placement box. The placement box drives the green compact to reciprocate, so that the range of the high-temperature flame acting on the green compact is larger. After the high-temperature treatment is completed, the cold air blown out by the cold air duct rapidly cools the hot green compact on the placement box, which can uniformly perform high-temperature and cooling treatment on the green compact and improve the operation effect.
