Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of metal shell drying equipment, specifically a drying device for microelectronic packaged metal shells. Background Technology
[0002] After processing, metal casings for microelectronic packaging may contain metal scraps, dust, and other impurities. They need to be further cleaned before packaging electronic components. Cleaning is usually done using an ultrasonic cleaner. After cleaning, batches of packaged metal casings need to be dried because of residual liquid on the surface.
[0003] A current method for drying metal casings for microelectronic packaging, as disclosed in patent publication CN221649003U, includes a drying chamber equipped with a drying mechanism, a driving mechanism, and a ventilation mechanism. The drying mechanism comprises a drying plate located inside the drying chamber and connected to the driving mechanism, which rotates the drying plate laterally. The drying plate has several placement slots, which are open. A rotating cover plate has several ventilation holes, the cross-sectional area of which is smaller than the cross-sectional area of the placement slots. When the rotating cover plate is detachably placed on the drying plate, each ventilation hole is positioned above a corresponding placement slot. The ventilation mechanism includes several fans mounted on the walls of the drying chamber, connecting the inside and outside of the chamber. This invention, by using a drying plate with placement slots, allows each metal casing to be independently placed in its respective slot during drying, preventing them from scratching each other.
[0004] While the above patents have solved the problems mentioned in the background technology, the following shortcomings still exist: 1. The drying plate in the device is not detachable, so it cannot be used for placing metal shells of different sizes, thus limiting the scope of use of the device and reducing its practicality; 2. The internal sealing effect of the device is not good, so during drying, it is easy to cause air to escape, which affects the distribution of airflow and results in uneven drying effect of the metal shell, which is not conducive to subsequent use.
[0005] In summary, this utility model solves the problems in the background art by designing a drying device for a microelectronic package metal shell. Utility Model Content
[0006] The purpose of this invention is to provide a drying device for the metal casing of microelectronic packaging to solve the problems mentioned in the background art.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] For examples, please refer to Figure 1-5 This utility model provides a technical solution;
[0028] A drying device for a metal casing of a microelectronic package includes a drying chamber 1 and a cover 2 on the top of the drying chamber 1. A controller 3 is provided on the rear side of the drying chamber 1, and an air outlet 4 is provided on the left side of the drying chamber 1. A drying chamber 5 is provided inside the drying chamber 1. An electric heater 501, a temperature sensor 502, a clamping plate 503, and an annular air duct 504 are provided inside the drying chamber 5. A positioning post 5031 and a clamping spring 5032 are fixedly provided on the outer side of the clamping plate 503. An air inlet pipe 5041 is provided on the right side of the annular air duct 504. A guide post 6 and a protrusion 7 are provided on the top of the drying chamber 1. A locking block 601 is provided on the top of the guide post 6. A guide hole 201 is provided on the top surface of the cover 2, and a groove 202 is provided on the bottom of the cover 2.
[0029] Specifically, there are multiple air outlets 4, all of which extend into the interior of the drying chamber 5. The annular air duct 504 is located at the top of the interior of the drying chamber 5, and the inner wall of the annular air duct 504 is provided with multiple inclined nozzles. The right end of the air inlet pipe 5041 passes through the right inner wall of the drying chamber 5 and extends to the right side of the drying box 1. The right end of the air inlet pipe 5041 is connected to the output end of the air pump.
[0030] In this embodiment, the combination of the air pump and the air inlet pipe 5041 can blow air into the inside of the annular air pipe 504 and spray it into the drying chamber 5 through the nozzle. The air outlet 4 is mainly used to discharge the gas inside the drying chamber 5, so as to facilitate the rapid drying of the metal shell on the placement plate 5033.
[0031] Specifically, the electric heater 501 is arranged in a ring-shaped winding configuration, and the electric heater 501 and the temperature sensor 502 are electrically connected to the controller 3 via wires.
[0032] In this embodiment, the electric heater 501 can heat the inside of the drying chamber 5, while the temperature sensor 502 monitors the internal temperature of the drying chamber 5 in real time, effectively preventing the internal temperature of the drying chamber 5 from becoming too high.
[0033] Specifically, the inner wall of the protrusion 7 fits into the outer surface of the groove 202, the cross-sectional shape of the groove 202 is annular, the position of the guide post 6 corresponds to the guide hole 201, and the outer surface of the guide post 6 fits into the inner wall of the guide hole 201. The locking block 601 rotates eccentrically with the top of the guide post 6 through the eccentric shaft, and the bottom surface of the locking block 601 forms frictional contact with the top surface of the cover 2. The cross-sectional dimensions of the locking block 601 are consistent with those of the guide post 6.
[0034] In this embodiment, the guide post 6 is mainly used to contact the guide hole 201, so as to realize the quick positioning of the box cover 2 and facilitate the engagement of the protrusion 7 and the groove 202. Under the eccentric rotation of the locking block 601 and the guide post 6, the locking block 601 and the top of the box cover 2 form a frictional contact, ensuring the airtightness between the box cover 2 and the drying box 1.
[0035] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The drying chamber 5 is equipped with a clamping plate 503 inside, and a positioning post 5031 and a clamping spring 5032 are fixedly installed on the outside of the clamping plate 503 respectively.
[0036] Specifically, the clamping plate 503 has an L-shaped structure and is made of silicone rubber. The clamping end of the clamping plate 503 is provided with a placement plate 5033. The top surface of the placement plate 5033 is provided with a placement groove. The clamping plate 503 is distributed in a left-right mirror image about the internal central axis of the drying chamber 5. The end of the positioning post 5031 away from the clamping plate 503 is sealed and movable through the inner wall of the drying chamber 5 and extends outward. The end of the clamping spring 5032 away from the clamping plate 503 is fixed to the inner wall of the drying chamber 5.
[0037] In this embodiment, the positioning post 5031 is mainly used to slide against the inner wall of the drying chamber 5 to ensure that the clamping plate 503 moves smoothly laterally. The clamping spring 5032 is mainly used to provide pre-pressure to the clamping plate 503, causing the clamping plates 503 to move towards each other, ensuring that the clamping plate 503 and the two ends of the placement plate 5033 are in stable contact, and meeting the subsequent fixing requirements of placement plates 5033 of different sizes.
[0038] The working principle and usage process of this utility model are as follows: When using a microelectronic package metal shell drying device, first connect the air pump to the right end of the air inlet pipe 5041 through a pipe. Then place the metal shell in the placement slot of the placement plate 5033. After placement, move the placement plate 5033 so that it is positioned between the clamping plates 503. At this time, the elastic support force of the clamping spring 5032 causes the opposing side surfaces of the clamping plate 503 to contact the two ends of the placement plate 5033. As the clamping plate 503 moves, the positioning post 5031 can slide against the inner wall of the drying chamber 5, ensuring stable contact between the clamping plate 503 and the placement plate 5033, which facilitates the subsequent fixing of placement plates 5033 of different sizes. Then, the chamber... The cover 2 is moved to bring it closer to the drying chamber 1. During this process, the guide hole 201 gradually contacts the guide post 6. As the cover 2 moves down, the protrusion 7 engages with the groove 202 until they are fully engaged. An external force is applied to the locking block 601, causing it to rotate eccentrically. The locking block 601 then generates contact friction with the bottom of the cover 2, achieving mechanical self-locking of the cover 2 and preventing airflow from escaping through the gap between the cover 2 and the drying chamber 1. Subsequently, the airflow is delivered to the annular air duct 504 through the combination of the air pump and the air inlet pipe 5041. The airflow enters the drying chamber 5 from the nozzle and exits through the air outlet 4. Under the flow of airflow, the metal shell can be dried, meeting the needs of the user.
