Description

Technical Field

[0001] This utility model relates to the field of diode manufacturing technology, and more specifically, it relates to a drying rack for diode manufacturing. Background Technology

[0002] Drying is a crucial step in the diode manufacturing process. Traditional drying equipment mostly uses static or unidirectional heating methods, which results in insufficient contact between the diode surface and the hot air, easily causing uneven drying. Some areas may be overheated or not completely dried. This uneven drying effect directly affects the quality and subsequent performance of the diode. Especially in the manufacturing of high-precision electronic components, the requirements for drying effect are even more stringent.

[0003] In addition, the lack of an effective material turning device causes some materials to remain in the "blind zone" of the airflow during the drying process, which further reduces the drying efficiency. These problems urgently require a new type of device that can achieve uniform heating and dynamic drying. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a drying rack for diode production, which has the following advantages:

[0017] 1. The feeding mechanism of this device can effectively solve the problem of uneven heating of materials in traditional drying equipment. Through the design of multiple feeding hoods, the materials are distributed in a closed and breathable hood. Hot air can enter the inside of the feeding hood through the air vents and fully contact the material surface to ensure the uniformity of the drying process. At the same time, the feeding hood can be rotated with the rotation of the drive shaft, so that the materials are always in a dynamic state, which further improves the uniformity of heating and drying efficiency.

[0018] 2. The drying mechanism, through the combination design of a hot air blower and a multi-layered annular pipe, can evenly deliver hot air to every corner of the drying drum. The multi-point distribution of the air outlet pipes ensures that the hot air can fully cover the internal space of the drying drum, avoiding the poor drying phenomenon caused by uneven hot air distribution in traditional equipment. At the same time, the hot air enters the interior of the placement hood directly through the vent holes, making full contact with the surface of the material, further improving the drying effect. In addition, the exhaust pipe can quickly remove moisture, forming a good hot air circulation system, which significantly improves drying efficiency.

[0019] 3. The linkage mechanism, through the linkage design of the motor and multiple sets of transmission shafts, achieves synchronous rotation of the placement hood. During the rotation of the placement hood, the material is constantly turned over, and the contact surface with the hot air is constantly changing, ensuring more uniform drying. Through the meshing design of bevel gears and bevel gear rings, the linkage mechanism can efficiently transmit power and drive multiple sets of transmission shafts to operate simultaneously, ensuring the stability and reliability of the equipment operation. At the same time, the sealed bearing design between the transmission shaft and the drying cylinder effectively prevents airflow leakage, further improving the drying performance and energy-saving effect of the equipment.

[0030] The material feeding mechanism is equipped with two sets installed inside the drying cylinder 1. The material is reasonably distributed by the two sets of material feeding mechanisms, so that the material is heated evenly and the drying efficiency is improved.

[0031] Multiple sets of drive shafts 3 extend out of the drying cylinder 1.

The sealed bearings effectively isolate the air and impurities inside and outside the drying cylinder, while ensuring the smooth rotation of the drive shafts.

[0032] The top of the drying cylinder 1 is provided with a top cover 15, and the top cover 15 is provided with an exhaust pipe 16. There are multiple sets of exhaust pipes 16. Through the reasonable arrangement of multiple exhaust pipes 16, the moisture inside the cylinder is quickly removed, reducing the interference of moisture on the drying process.

[0034] The hot air blower 11 is fixedly installed on the bottom surface of the drying cylinder 1 and its air outlet is connected to the output pipe 10. Hot air enters the drying cylinder through the output pipe 10 to realize the heating and drying process of the material.

[0035] In this embodiment, diode materials are first loaded into the placement cover 5, and the sealing plate 7 is fixed by bolts. During operation, the connecting block 2 is fixed to the inner wall of the drying cylinder 1. Multiple sets of drive shafts 3 are installed on the outer wall of the connecting block 2 and can rotate freely. The connecting sleeve 4 is fixed to the outer wall of the drive shaft 3 and rotates with it. The placement cover 5 is installed on the outside of the connecting sleeve 4, and the sealing plate 7 is provided inside the placement cover 5. The sealing plate 7 is tightly fixed to the placement cover 5 through the bolt holes 8 and fixing bolts 9 to form a sealed space, ensuring that the material will not fall.

An air outlet pipe 14 is installed between the annular pipe 13 and the connecting pipes 12. The hot air is evenly distributed into the inside of the drying cylinder 1 through these air outlet pipes 14. Throughout the process, the hot air enters the placement hood 5 through the vent 6 to ensure that the material is heated evenly in a closed environment, thereby achieving a highly efficient drying effect.

[0036] Please see Figures 1-4 As one implementation of the linkage mechanism: the outer wall of the drying cylinder 1 is provided with a linkage mechanism, which includes a mounting plate 18, a motor 19, a first bevel gear 20, a second bevel gear 21, a first bevel gear ring 22, and a second bevel gear ring 23. The mounting plate 18 is mounted on the outer wall of the drying cylinder 1, and the motor 19 is mounted on the mounting plate 18. The first bevel gear 20 and the second bevel gear 21 are each provided with multiple sets of mounting and are respectively mounted on multiple sets of transmission shafts 3. The first bevel gear ring 22 is rotatably mounted on the outer wall of the drying cylinder 1 and meshes with multiple sets of first bevel gears 20. The second bevel gear ring 23 is mounted on the top surface of the first bevel gear ring 22 and meshes with multiple sets of second bevel gears 21.

[0037] The output end of the motor 19 is fixedly connected to a set of transmission shafts 3. The transmission shafts 3 are driven to rotate by the motor 19, thereby realizing the tumbling of the material inside the drying cylinder 1.

[0038] More specifically, when the motor 19 starts, power is transmitted through bevel gears. The first bevel gear 20 meshes with the first bevel gear ring 22, driving the first bevel gear ring 22 to rotate. The first bevel gear ring 22 is connected to the second bevel gear ring 23 to rotate synchronously, transmitting power to the second bevel gear 21. The second bevel gear 21 drives multiple sets of transmission shafts 3, causing the transmission shafts 3 and the placement cover 5 on them to rotate synchronously. During the rotation, the material is constantly turned over, ensuring that the contact surface with the hot air is constantly changing, thus achieving uniform drying.

[0039] In summary, during the use or operation of the overall equipment: First, the diode material is loaded into the placement cover 5, and the sealing plate 7 is fixed by the bolts. During operation, the connecting block 2 is fixed to the inner wall of the drying cylinder 1. Multiple sets of drive shafts 3 are installed on the outer wall of the connecting block 2 and can rotate freely. The connecting sleeve 4 is fixed to the outer wall of the drive shaft 3 and rotates with it. The placement cover 5 is installed on the outside of the connecting sleeve 4, and the sealing plate 7 is set inside the placement cover 5. The sealing plate 7 is tightly fixed to the placement cover 5 through the bolt holes 8 and the fixing bolts 9 to form a sealed space to ensure that the material will not fall. The placement cover 5 has ventilation holes 6 distributed on it, which allow hot air to circulate and achieve uniform material distribution. After the material is placed, the hot air blower 11 is activated, and the generated hot air is delivered to the inside of the drying cylinder 1 through the output pipe 10. Multiple sets of connecting pipes 12 are connected to the outer wall of the output pipe 10. The connecting pipes 12 are further connected to the annular pipes 13 installed on them. The annular pipes 13 are evenly distributed to ensure that the hot air is delivered to every area inside the drying cylinder 1. An air outlet pipe 14 is installed between the annular pipe 13 and the connecting pipe 12. The hot air is evenly distributed into the inside of the drying cylinder 1 through these air outlet pipes 14. Throughout the process, the hot air enters the placement hood 5 through the vent 6 to ensure that the material is heated evenly in a closed environment, thereby achieving a highly efficient drying effect.

[0040] When the motor 19 starts, power is transmitted through the bevel gear. The first bevel gear 20 meshes with the first bevel gear ring 22, driving the first bevel gear ring 22 to rotate. The first bevel gear ring 22 is connected to the second bevel gear ring 23 and rotates synchronously, transmitting power to the second bevel gear 21. The second bevel gear 21 drives multiple sets of transmission shafts 3, causing the transmission shafts 3 and the placement cover 5 on them to rotate synchronously. During the rotation, the material is constantly turned over, ensuring that the contact surface with the hot air is constantly changing, thus achieving uniform drying.
