Referring to fig. 1, 2 and 3, an oven door device provided in an embodiment of the present application is used for opening and closing an oven tube of a diffusion furnace, and the oven door device includes an oven door body 10 and an adjusting member 20, where the oven door body 10 is used for abutting against an orifice of the oven tube, so as to close the orifice of the oven tube and seal the oven tube. The adjusting piece 20 is connected with the furnace tube body and can controllably drive the furnace door body 10 to move along a first direction X, and the first direction X is parallel to the direction of the axis of the furnace door body 10, so that the furnace door body 10 is driven to be abutted or separated from the tube orifice of the furnace tube by the movement of the adjusting piece 20 in the first direction X, and the effect of opening and closing the furnace tube is achieved.
If the furnace tube is opened and closed directly by the movement of the furnace door body 10 in the first direction X, when the furnace door body 10 closes the tube orifice of the furnace tube, the furnace door body 10 contacts with the tube orifice of the furnace tube at a certain speed and generates a larger impact force, so that the furnace door body 10 can generate larger noise and vibration due to the impact while closing the tube orifice, and the furnace door body 10 is very easy to knock the tube orifice of the furnace tube.
For this reason, the oven door device further comprises a hydraulic buffer 30, the hydraulic buffer 30 is mounted on the adjusting member 20, and the hydraulic buffer 30 comprises a piston rod 31 compressible along the first direction X, one end of the piston rod 31 is abutted against the oven door body 10, and the hydraulic buffer 30 can buffer and slow down to stop the object acting thereon by means of hydraulic damping, thereby playing a certain protection role.
Thus, when the furnace door body 10 contacts the mouth of the furnace tube at a certain initial speed, the impact force generated by the furnace door body 10 and the furnace tube acts on the piston rod 31 of the hydraulic buffer 30 and compresses the piston rod 31, and the hydraulic oil in the hydraulic buffer 30 provides a resistance force with nearly fixed magnitude to the piston rod 31 in the compression process of the piston rod 31, the resistance force is opposite to the direction of the impact force, so that the impact force on the furnace door body is reduced by the impact force absorbed by the hydraulic buffer, and after the impact force is absorbed by the hydraulic piston rod, the kinetic energy of the piston rod 31 is converted into heat energy, and finally the heat energy is emitted into the air. That is, the impact generated when the furnace door body 10 contacts the furnace tube is absorbed by the hydraulic buffer 30, thereby reducing the vibration and noise generated when the furnace tube is closed by the furnace door body 10, reducing the probability of the furnace tube being broken by the furnace door body 10, further improving the opening probability of the diffusion furnace, prolonging the mechanical life, reducing the maintenance cost, simplifying the mechanical design, improving the production efficiency of the semiconductor, and the like.
In the actual use process, after the furnace door body 10 closes the furnace tube, the connection point between the adjusting member 20 and the furnace door body 10 is usually at the geometric center of the furnace door body, so that the part of the furnace door body 10 away from the geometric center, i.e. the periphery of the furnace door body 10, will have a tilting phenomenon, resulting in the sealing of the furnace tube being not tight. Wherein, the furnace door body 10 is disc-shaped, and the geometric center of the furnace door body is the center of the disc.
To this end, in some embodiments of the present application, the adjusting member 20 is connected to the geometric center of the oven door body 10, and a plurality of hydraulic buffers 30 are disposed at intervals around the axis of the oven door body 10 on the adjusting member 20. From the above, the hydraulic oil in the hydraulic buffer 30 provides a resistance force for the piston rod 31, so that the piston rod 31 of the hydraulic buffer 30 can be pressed against the furnace door body 10 and the furnace tube by the resistance force provided by the hydraulic oil after the furnace door body 10 is closed to the furnace tube, thereby avoiding the tilting of the furnace door body 10. By arranging the plurality of hydraulic buffers 30, the periphery of the furnace door body 10 can be pressed on the furnace tube through the hydraulic buffers 30, and the sealing effect of the hydraulic buffers 30 is further ensured.
In some embodiments, the adjusting member 20 includes a connection portion 21 and a plurality of buffer portions 22, the connection portion 21 being connected to the geometric center of the oven door body 10, the plurality of buffer portions 22 being radially arranged around the circumference of the connection portion 21 to enable the adjusting member 20 to extend from the geometric center position of the oven door body 10 to the periphery of the oven door body 10 through the plurality of buffer portions 22 being radially arranged so as to position the plurality of hydraulic buffers 30 at positions close to the periphery of the oven door body 10.
In some embodiments, the hydraulic buffer 30 is disposed at one end of each buffer portion 22 facing away from the connecting portion 21, so that each hydraulic pipe device can be disposed at a position close to the periphery of the furnace door body 10, so as to compress the periphery of the furnace door body 10 with the furnace pipe, avoid tilting of the furnace door body 10, and ensure the hydraulic effect of the furnace pipe.
In the embodiment of fig. 2, the furnace door device has three hydraulic buffers 30, and the furnace door body 10 has three positions capable of being pressed against the furnace tube, while in the embodiments of fig. 4 and 5, the furnace door device has six hydraulic buffers 30, so that in the embodiment, the furnace door body 10 has six positions capable of being pressed against the furnace tube, and so on, if the number of the hydraulic buffers 30 is greater, the pressing effect of each position around the furnace door body 10 against the furnace tube is better, and therefore the number of the hydraulic buffers 30 determines the pressing effect of the furnace door body 10 against the furnace tube.
In order to further increase the number of hydraulic buffers 30, referring to fig. 6 and 7, in particular to some embodiments, the adjusting member 20 further includes a mounting ring 23, the mounting ring 23 is disposed around the connecting portion 21 and connects one end of each buffer portion 22 facing away from the connecting portion 21, all the hydraulic buffers 30 are disposed on the mounting ring 23, so that the adjusting member 20 can accommodate a greater number of hydraulic buffers 30 through the hydraulic ring, as in the embodiments of fig. 6 and 7, the adjusting member 20 can be provided with 12 hydraulic buffers 30 through the mounting ring 23, so that the compacting effect of the furnace door body 10 and the furnace tube is greatly improved, and the sealing performance of the furnace tube is better.
In some embodiments of the present application, in order to drive the furnace door body 10 to open and close the furnace tube, the furnace door device includes a first driving member 40, where the first driving member 40 is in transmission connection with the adjusting member 20, so as to drive the adjusting member 20 to drive the furnace door body 10 to move along the first direction X.
Wherein, furnace gate device still includes support 41, and support 41's one end and first driving piece 40 transmission are connected, and regulating part 20 still includes fixed part 24, and fixed part 24 protrusion sets up on the one side that regulating part 20 deviates from furnace gate body 10, and the bottom of fixed part 24 sets up in support 41's the other end, and support 41 not only plays the driven effect like this, can also support regulating part 20 and furnace gate body 10 together through support 41.
In some embodiments, the oven door device comprises a second driving member 42, wherein the second driving member 42 is in transmission connection with the adjusting member 20 to drive the adjusting member 20 to move the oven door body 10 along a second direction Y, and the second direction Y intersects the first direction X so as to drive the oven door body 10 away from the oven tube through the second driving member 42. In the actual use process, the furnace door body 10 can be driven to move along the first direction X so as to open the furnace tube, and then the furnace door body 10 is driven to move along the second direction Y so as to avoid the furnace door body 10 from the tube orifice of the furnace tube, so that the parts to be processed can be taken out and put in.
In particular, in some embodiments, the first driving member 40 and the second driving member 42 are each an air cylinder, and the output shaft of the first driving member 40 is connected to the second driving member 42, and the output shaft of the second driving member 42 is connected to the adjusting member 20 through the bracket 41. Thus, when the first driving member 40 is operated, the first driving member 40 drives the second driving member 42, the bracket 41, the adjusting member 20 and the furnace door body 10 to move together in the first direction X for opening and closing the furnace tube. When the second driving member 42 is operated, the second driving member 42 drives the furnace door body 10 to move along the second direction Y through the bracket 41 and the adjusting member 20, so as to approach or avoid the furnace tube. In other embodiments, the first driving motor and the second driving motor may be a linear motor or other components for outputting linear motion, which is not limited herein.
In some embodiments of the present application, the oven door body 10 includes a quartz door body 11 and a sealing door body 12, one side of the sealing door body 12 is provided with the quartz door body 11, the opposite side is provided with the adjusting piece 20, and the size of the quartz door body 11 is smaller than the size of the sealing door body 12, so that the quartz door body 11 can extend into the oven tube to insulate the oven door body 10 through the quartz door body 11. The sealing door 12 is used for being abutted against the furnace tube so as to seal the furnace tube, and the adjusting piece 20 is arranged on the sealing door 12, so that the sealing door 12 can improve the compacting effect of the sealing door 12 and the furnace tube through the hydraulic buffer piece on the adjusting piece 20.
The present application also provides a diffusion furnace, including the furnace tube and the furnace door device in any one of the above embodiments, the furnace door device is used for opening and closing the furnace tube, and when the furnace door body 10 contacts with the mouth of the furnace tube at a certain initial speed, the impact that the furnace tube produced with the furnace door body 10 can act on the piston rod 31 of the hydraulic buffer 30, and compress the piston rod 31, and the piston rod 31 can provide a nearly fixed size resistance force through the hydraulic oil in the hydraulic buffer 30 in the process of compression, thereby making the kinetic energy of the piston rod 31 convert into heat energy, finally give off into air. That is, the impact generated when the furnace door body 10 contacts the furnace tube is absorbed by the hydraulic buffer 30, thereby reducing the vibration and noise generated when the furnace tube is closed by the furnace door body 10, reducing the probability of the furnace tube being broken by the furnace door body 10, further improving the opening probability of the diffusion furnace, prolonging the mechanical life, reducing the maintenance cost, simplifying the mechanical design, improving the production efficiency of the semiconductor, and the like.
