A sintering furnace is a mechanical device for sintering electronic components. The sintering furnace is composed of a furnace body shell, heat insulation materials, a furnace chamber, heating elements, a controller, and a temperature meter.

[0003] In the prior art, during the production process of electronic components, some electronic components, such as semiconductor materials, resistors, capacitors, etc., can improve the material structure and electronic performance of these components through sintering operations.

However, the following problems will occur in this operation: After the sintering operation is completed, it is necessary to wait for the furnace chamber, electronic components, container, and backing plate to cool completely before the door panel can be opened, and the staff manually takes out the products.

[0019] Compared with the related art, the sintering furnace structure for electronic component production provided by the present utility model has the following beneficial effects:

[0020] The utility model provides a sintering furnace structure for electronic component production. During the production process of electronic components, some electronic components, such as semiconductor materials, resistors, capacitors, etc., can improve the material structure and electronic performance of these components through sintering operations. Place the specified material in a ceramic container, then place the container on a backing plate, and put the raw material, container, and backing plate into the sintering furnace together. Set the heating temperature and heating duration of the sintering furnace, and wait for the firing to end. However, the following problems will occur in this operation. After the sintering operation is completed, it is necessary to wait for the furnace chamber, electronic components, container, and backing plate to cool completely before opening the door panel. The staff manually takes out the products. Due to the good heat preservation effect of the sintering furnace, it takes a long time to wait for cooling, and the production efficiency is low. The door panel can be opened below 200 degrees Celsius, and the furnace chamber material will not be damaged. Opening the door panel before complete cooling to accelerate cooling can improve production efficiency, but the residual heat in the furnace chamber is likely to damage the staff. By setting an adjustment structure, after the temperature of the furnace chamber drops below 200 degrees Celsius, open the door panel and start the electric push rod. The electric push rod drives the adjustment frame to move upward. The adjustment frame drives the moving rod and the support claws to rise to the furnace chamber. Start the servo motor. The servo motor drives the gear to rotate. The gear drives the rack to move towards the furnace chamber. The rack drives the moving rod and the support claws to move towards the furnace chamber. During this process, the moving rod and the limit rod always slide along the adjustment frame to drive the support claws into the backing plate. Under the action of the electric push rod, the support claws lift the backing plate upward. Then the servo motor rotates in the reverse direction, so that the support claws drive the backing plate and the electronic component products on the backing plate to be pushed out of the furnace chamber. Then the electric push rod contracts, so that the support claws drive the backing plate to move downward to the square hole of the furnace outer frame. The servo motor rotates, so that the support claws drive the backing plate to extend above the conveyor belt. The electric push rod further contracts, and the support claws lower the backing plate onto the conveyor belt. The servo motor rotates in reverse, and the support claws withdraw from above the conveyor belt. Start the motor. The motor drives the conveyor belt to rotate through the rotating shaft, so that the discharged backing plate and electronic component products move along with the conveyor belt. At this time, the backing plate, container, and raw material pre-placed on the conveyor belt move to the square hole on the furnace outer frame. Similarly, start the servo motor and the electric push rod, so that the support claws lift the backing plate and put the backing plate into the furnace chamber. Then the staff closes the door panel for sintering operation, realizing the movement of the backing plate by using the support claws that can move in multiple directions, and then carrying out the loading and unloading operations of the electronic components before or after sintering. The automation degree is high, avoiding scalding the staff by the residual heat of the equipment and products during manual loading and unloading, and can effectively improve the production efficiency.

[0032] The working principle of a sintering furnace structure for electronic component production provided by the present utility model is as follows: During the production of electronic components, some electronic components, such as semiconductor materials, resistors, capacitors, etc., can improve the material structure and electronic performance of these components through sintering operations. Place the specified material in a ceramic container, then place the container on the backing plate 4, and put the raw material, container, and backing plate 4 into the sintering furnace together. Set the heating temperature and heating duration of the sintering furnace, and wait for the firing to end. However, the following problems will occur in this operation. After the sintering operation is completed, it is necessary to wait for the furnace chamber 3, electronic components, container, and backing plate 4 to cool completely before opening the door panel 2, and the staff manually takes out the products. Due to the good heat preservation effect of the sintering furnace, it takes a long time to wait for cooling, resulting in low production efficiency. The door panel 2 can be opened below 200 degrees Celsius, and the material of the furnace chamber 3 will not be damaged. Opening the door panel 2 before complete cooling to accelerate cooling can improve production efficiency, but the residual heat in the furnace chamber 3 is likely to damage the staff. By setting the adjustment structure 5, after the temperature of the furnace chamber 3 drops below 200 degrees Celsius, open the door panel 2, start the electric push rod 502, and the electric push rod 502 drives the adjustment frame 503 to move upward. The adjustment frame 503 drives the moving rod 505 and the support claw 507 to rise to the furnace chamber 3. Start the servo motor 510, and the servo motor 510 drives the gear 511 to rotate. The gear 511 drives the rack 509 to move in the direction close to the furnace chamber 3. The rack 509 drives the moving rod 505 and the support claw 507 to move in the direction close to the furnace chamber 3. During this process, the moving rod 505 and the limiting rod 506 always slide along the adjustment frame 503 to drive the support claw 507 into the backing plate 4. Under the action of the electric push rod 502, the support claw 507 lifts the backing plate 4 upward. Then the servo motor 510 rotates in the reverse direction, so that the support claw 507 drives the backing plate 4 and the electronic component products on the backing plate 4 out of the furnace chamber 3. Then the electric push rod 502 contracts, so that the support claw 507 drives the backing plate 4 to move downward to the square hole of the furnace outer frame 1. The servo motor 510 rotates, so that the support claw 507 drives the backing plate 4 to extend above the conveyor belt 515. The electric push rod 502 further contracts, and the support claw 507 lowers the backing plate 4 onto the conveyor belt 515.

Start the motor 516, and the motor 516 drives the conveyor belt 515 to rotate through the rotating shaft 514, so that the out-of-furnace backing plate 4 and electronic component products move along with the conveyor belt. At this time, the backing plate 4, container, and raw material pre-placed on the conveyor belt 515 move to the square hole on the furnace outer frame 1.

Then the staff closes the door panel 2 for sintering operations. Among them, the adjustment frame 503 is further limited by the sliding rod 504 to make the movement of the adjustment frame 503 more stable.

Through the identification groove 517, it is convenient for the user to accurately place the electronic components and the backing plate 4 for the next round of production on the conveyor belt 515. The motor 516 is shielded and protected by the protective cover 518. The conveyor belt 515 made of aramid fiber as the skeleton material has high heat resistance and is suitable for conveying high-temperature items. It realizes moving the backing plate 4 by the support claws 507 that can move in multiple directions, and then loading and unloading the electronic components before or after sintering.
