Description

Technical Field

[0001] The utility model relates to the technical field of sintering furnaces, and more specifically, to a discharging platform for sintering furnaces. Background Art

[0002] Sintering furnace is a special equipment that heats powder or powder compact to a temperature lower than the melting point of its basic components and then cools it to room temperature in a certain way and speed to obtain the required physical, mechanical properties and microstructure. Sintering furnace is often used to dry the slurry on silicon wafers, remove organic components in the slurry, and complete the sintering of aluminum back field and gate lines.

[0003] At present, after the sintering of the materials in the sintering furnace is completed, a discharging platform is usually used to discharge the sintered materials. However, it is usually necessary for the operator to manually operate the discharging process after the sintering is completed. After the discharging plate is moved out from the bottom or top of the sintering furnace, the material is transferred from the discharging plate which still maintains a high temperature. After the discharging plate is moved out, the material is clamped and moved to a cooling device for air cooling or water cooling.

[0004] Since the temperature of the discharge platform remains high after sintering is completed, the operator is at risk of accidentally touching the discharge platform and being scalded by the high temperature during the material transfer process. At the same time, since the operation process is cumbersome and complicated, the material needs to be removed from the discharge platform before it can be cooled, which affects the discharge efficiency and cooling efficiency of the sintering furnace. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a discharging platform for a sintering furnace which can automatically discharge materials and complete cooling.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a discharge platform for a sintering furnace, comprising a sintering furnace body, a control mechanism installed on the outer wall of the sintering furnace body, and a discharge mechanism and a cooling mechanism installed below the sintering furnace body.

[0007] Wherein, the sintering furnace body comprises a sintering furnace door rotatably connected to the sintering furnace body near the water pump side, and a sintering furnace door lock is installed on the upper outer side of the sintering furnace door.

[0008] The discharging mechanism comprises a discharging platform installed directly below the sintering furnace body, a threaded rod and a fixed rod passing through a movable slider below the discharging platform, and a motor connected to the threaded rod.

[0009] The cooling mechanism is installed directly below the sintering furnace body. The cooling mechanism is equipped with a water pump. A water inlet pipe and a cooling pipe are connected to the water pump. The end of the cooling pipe away from the water inlet pipe is connected to a water outlet pipe.

[0010] The utility model is further configured as follows: the discharging platform is directly below the sintering furnace body and is slidably connected to the lower side wall of the sintering furnace body, the threaded rod passes through the threaded hole in the middle of the movable slider and is rotatably connected to the motor, the motor is fixed to the side of the discharging mechanism close to the water outlet pipe, the fixed rod is placed on both sides of the threaded rod and passes through the two holes of the movable slider and is connected to the base of the discharging mechanism.

[0011] By adopting the above technical solution, after the sintering of the sintering furnace body is completed, the control system controls the prompt light to flash, prompting the operator to press the discharge control key, and the control system controls the sintering furnace door lock to unlock, then the sintering furnace door opens and the motor starts. The motor starts to control the threaded rod to rotate and drive the moving slider and the discharge platform above the moving slider to move out of the sintering furnace body, which simplifies the discharge process and improves the discharge efficiency.

[0012] The utility model is further configured as follows: the water pump is installed below the sintering furnace body and is fixed on the inner wall of the discharge mechanism near one side of the sintering furnace door.

[0013] The utility model is further configured as follows: the cooling pipe is connected to the water outlet of the water pump in a "bow" shape, and the water outlet pipe passes through a hole of the discharge mechanism close to the side wall of the motor and is connected to the cooling pipe.

[0014] By adopting the above technical solution, when the control system recognizes that the discharging platform is completely moved out of the sintering furnace body and moved to directly above the water cooling mechanism, the control system controls the water pump to start and continuously inject cooling water into the cold water pipe to cool the discharging platform and the materials on the discharging platform, thereby eliminating the need for the operator to transfer the materials and then cool them down, avoiding the risk of the operator accidentally touching the high-temperature discharging platform and getting burned.

[0015] The utility model is further configured as follows: a control system is arranged inside the control mechanism, a discharging control key is installed on the upper side of the side wall of the control mechanism, a feeding control key is installed on the lower side, and a control panel is arranged on the right side of the discharging control key and the feeding control key.

[0016] The utility model is further configured as follows: a plurality of rectangular parallelepiped heating tubes are symmetrically installed on the inner walls of both sides of the sintering furnace body.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] (1) After sintering is completed, the control system built into the control mechanism makes the prompt light flash. After the operator presses the discharge control key in the control mechanism, the control system built into the control mechanism controls the motor to start, driving the threaded rod to rotate. The rotation of the threaded rod drives the moving slider and the discharge platform above it to move out of the sintering furnace body, completing the automatic discharge process. No manual discharge operation is required, avoiding the risk of operators accidentally touching the high-temperature discharge platform and being scalded, and the risk of operators accidentally damaging the sintered finished products, thereby improving the discharge efficiency.

[0019] (2) After the discharge is completed, the control system recognizes that the discharge platform has been completely moved out of the sintering furnace body and stays just above the cooling mechanism, then controls the water pump to start, allowing cooling water to flow in continuously through the bow-shaped cooling pipe and be continuously discharged through the water outlet pipe. The cooling water pipe is in direct contact with the discharge platform, and the heat of the discharge platform and the material above it is removed through the temperature difference between the two. There is no need for the operator to move the material away for cooling, which improves the cooling efficiency.

[0020] (3) The discharge platform can be used as a feeding platform before sintering starts. The operator only needs to place the material on the discharge platform before sintering starts, start the feeding control key, and input the sintering temperature and time on the operation panel. The control system inside the control structure will make the motor rotate in the opposite direction to retract the discharge platform, and after recognizing that the discharge platform has retracted into the sintering furnace body, it will close the sintering furnace door and lock the sintering furnace door, thereby improving the feeding efficiency.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0031] For example, see Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0032] Specifically, it refers to a discharging platform for a sintering furnace, including a sintering furnace body 1, a discharging mechanism 2, a cooling mechanism 3 and a control mechanism 4. The discharging mechanism 2 and the cooling mechanism 3 are installed directly below the sintering furnace body 1, and the control mechanism 4 is installed on the outer wall of the sintering furnace body 1. A sintering furnace door 101 is rotatably connected to the side of the sintering furnace body 1 close to a water pump 301, and a sintering furnace door lock 104 is installed on the upper outer side of the sintering furnace door 101. A warning light 103 is installed directly above the control mechanism 4, and a plurality of heating tubes 102 are symmetrically installed in parallel on both sides of the inner wall of the sintering furnace body 1.

[0033] The discharging mechanism 2 includes a discharging platform 201, which is located directly below the sintering furnace body 1 and is slidably connected to the inner side of the bottom of the sintering furnace body 1. The discharging platform 201 is tightly fixed to the moving slider 204. The fixing rod 203 passes through the left and right holes in the moving slider 204 on both sides of the threaded rod 202 to fix the moving slider 204 on the base of the discharging mechanism 2. The threaded rod 202 passes through the threaded hole in the middle of the moving slider 204 and is connected to the motor 205 directly behind the moving slider 204. When sintering is completed, the control mechanism 4 flashes the prompt light 103 through its internal control system to prompt the operator, and the operator presses the discharge control key 401 on the control mechanism 4 to discharge the material. The control mechanism 4 unlocks the sintering furnace door lock 104 and opens the sintering furnace door 101 through its internal control system and starts the motor 205. The motor 205 drives the threaded rod 202 to rotate, and the threaded rod 202 drives the moving slider 204 and the discharge platform 201 above it to move parallelly out of the sintering furnace body 1 to complete the discharge process. The control system in the embodiment can be used, for example, to include a PLC and a central server based on the sensor signal detected by the temperature sensor used and a time controller to control the feeding and discharging of the material.

[0034] Before sintering begins, the discharge platform 201 can also be used as a feeding platform. The operator places the material to be sintered on the discharge platform 201, presses the feeding control key 402 on the control mechanism 4, and enters the temperature and time required for sintering on the operation panel 403 to the right of the feeding control key 402. Then the motor 205 rotates in the opposite direction to drive the threaded rod 202 to move the movable slider 204 and the discharge platform 201 back into the sintering furnace body 1, completing the feeding process.

[0035] For example 2, please refer to Figure 1 , Figure 3The second embodiment makes the following improvements on the basis of the first embodiment: since the discharge platform 201 still maintains a high temperature after sintering is completed, there is a risk of operators being burned by accidental contact when transferring materials, and the materials need to be removed from the discharge platform 201 before they can be cooled down, and the discharge efficiency and cooling efficiency of the sintering furnace are not high. Therefore, in this embodiment, a cooling mechanism 3 is arranged directly below the sintering furnace body 1, and the cooling mechanism 3 includes a water pump 301, a cooling pipe 302, a water inlet pipe 303, a water outlet pipe 304 and a support frame 305. The water inlet pipe 303 passes through the side wall hole of the discharging mechanism 2 on the side close to the water pump 301 and is connected to the water inlet on the side of the water pump 301. The cooling pipe 302 is connected to the water outlet of the water pump 301 in a bow shape, and the water outlet pipe 304 passes through the hole on the inner wall of the discharging mechanism 2 on the side close to the motor 205. The support frame 305 is fixed on the base of the discharging mechanism 2. Since the water pump 301 will vibrate during operation, causing the cooling pipe 302 to be displaced, the support frame 305 makes the cooling pipe 302 stable and does not shake, thereby avoiding the influence of the vibration of the water pump 301 on the cooling pipe 302 and ensuring that the cooling pipe 302 is not displaced.

[0036] After the discharging is completed, the discharging platform 201 moves to the top of the cooling mechanism 3, and the control system inside the control mechanism 4 controls the water pump 301 to start, and the cooling water is continuously delivered into the cooling pipe 302 through the water inlet pipe 303. The heat of the discharging platform 201 is brought out by the heat difference, and the heat of the discharging platform 201 above it is cooled, and the heat is continuously discharged through the water outlet pipe 304, so that the material on the discharging platform 201 and the discharging platform 201 itself are reduced to the required temperature, which is convenient for the operator to carry out the next operation, reduces the risk of injury to the operator, and improves the discharging efficiency and cooling efficiency.

[0037] The working principle of a discharge platform for a sintering furnace provided by the utility model is as follows:

[0038] See also Figure 1-4 Before sintering begins, the discharge platform 201 is used as the feeding platform. The operator places the material on the discharge platform 201 and presses the feeding operation key 402, and inputs the time and temperature on the operation panel 403. The control system inside the control mechanism 4 controls the motor 205 to rotate in the opposite direction to drive the discharge platform 201 back into the sintering furnace body 1, and controls the sintering furnace door 101 to close and then the sintering furnace door lock 104 to lock. After sintering is completed, the control system inside the control mechanism 4 controls the prompt light 103 to flash, and the operator presses the discharge control key 401, and the control system controls the sintering furnace door lock 104 to unlock, the sintering furnace door 101 opens, and the discharge platform moves to the top of the cooling mechanism 3 for cooling.

[0039] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
