Description

Technical Field

[0001] The utility model belongs to the technical field of radio frequency module processing devices, and in particular relates to a radio frequency module packaging device. Background Art

[0002] With the rapid development of wireless communication technology, the stability and reliability of RF module performance are of immeasurable value in ensuring the smooth operation of communication systems. In the fine manufacturing process of RF modules, the packaging quality is directly related to the module's heat dissipation efficiency, the stability of electrical connections, and the stable performance under long-term operation.

[0003] However, the traditional RF module packaging device has exposed a series of problems in practical applications, which have become the key factors restricting the improvement of module performance and the reduction of manufacturing costs. First, uneven heating of the colloid is a common problem. Due to the uneven temperature distribution during the heating process, the colloid is prone to uneven curing or stratification, which not only affects the performance of the colloid itself, but may also cause problems such as poor electrical connection or unstable signal transmission in the packaged RF module.

[0004] Secondly, low heat dissipation efficiency is also a major challenge faced by traditional packaging devices. During the operation of the RF module, a large amount of heat will be generated. If it cannot be dissipated promptly and effectively, the internal temperature of the module will be too high, which will cause component damage or performance degradation. Traditional heat dissipation methods are often unable to meet the high heat dissipation requirements of RF modules, especially in high-power and high-density working environments. This problem is more prominent. Utility Model Content

[0005] The utility model provides a radio frequency module packaging device, which aims to solve the problems of uneven heating and low heat dissipation efficiency in traditional radio frequency module packaging devices. Uneven temperature distribution during heating leads to uneven curing or stratification of the colloid. At the same time, the heat dissipation capacity is insufficient, which makes it difficult to meet the heat dissipation requirements under high power and high density work, and easily leads to overheating and damage of the module.

[0007] Preferably, the second packaging structure includes: a packaging seat sliding on the base; a lower template is provided inside the packaging seat, and a cooling groove is provided between the lower template and the packaging seat; cold water tanks are provided on both sides of the assembly frame, and the cold water tanks are filled with coolant; the outer sides of the two cold water tanks are connected to a second pump body, and the other end of the second pump body is connected to the cooling groove through a flexible pipe.

[0008] Preferably, an electric push rod is provided on a side of the assembly frame opposite to the packaging seat, and a telescopic end of the electric push rod is connected to a side wall of the packaging seat.

[0009] Preferably, a guide groove for the sliding of the assembly frame is provided in the middle of the upper surface of the base.

[0010] Preferably, heat dissipation fins are provided on the outer side of the cold water tank.

[0011] Preferably, a first motor is disposed at the top of the assembly frame, and an output end of the first motor is fixedly connected to an end key of the screw rod.

[0012] Preferably, a second motor is provided at the top of the loading box, and an output end of the second motor is fixedly connected to an end key of the stirring shaft.

[0013] Preferably, temperature sensors are provided in both the loading box and the cooling tank.

[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0015] Firstly, by introducing the first packaging structure, the device ensures that the upper template can be smoothly and accurately moved to the predetermined position where it merges with the lower template; in addition, the device is also equipped with a loading member, which continuously rotates the stirring shaft driven by the second motor to evenly stir the colloid in the heating block; this stirring action not only makes the colloid heated more evenly, but also effectively prevents the solidification or stratification of the colloid that may occur during the heating process, thereby ensuring the uniformity and stability of the colloid and providing high-quality colloid materials for the subsequent packaging process.

[0016] Second: This device realizes an efficient heat dissipation system through the second packaging structure; the coolant flows freely in the cooling tank and is in close and full contact with the lower template, thereby effectively absorbing the heat generated during the packaging process; in order to maintain the continuous low temperature of the coolant, this device adopts a strategy of alternating the use of two cold water tanks, which ensures that when the temperature of the coolant in one cold water tank rises, it can be immediately switched to another cold water tank with a lower temperature, and so on; this design greatly improves the heat dissipation efficiency, effectively protects the RF module from overheating damage, and ensures the stability of the packaging process and the long-term reliability of the RF module.

[0017] Third: This device is designed with a movable packaging seat, which can flexibly slide to different working positions along the guide groove according to actual needs. This design not only adapts to the switching needs of loading and unloading processes, but also facilitates the precise adjustment of the alignment position between the packaging seat and the upper template, ensuring the accuracy and consistency of the packaging process. This high degree of flexibility greatly improves the efficiency of the packaging process, making the entire production process smoother and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The present utility model provides a radio frequency module packaging device, such as Figure 1-4 As shown, it includes a base 1; a first packaging structure arranged on the base 1; and a second packaging structure arranged next to the first packaging structure; wherein the first packaging structure includes: an assembly frame 2 arranged on the base 1; a screw rod 3 and a group of guide rods 4 arranged in the assembly frame 2, and the screw rod 3 is rotatably matched with the assembly frame 2; a lifting block 5 is threadedly matched on the screw rod 3, and the lifting block 5 is slidably matched with two guide rods 4; an upper template 6 arranged at the bottom position of the lifting block 5; a feeding piece arranged on the lifting block 5; the feeding piece includes: a feeding box 7 arranged on the lifting block 5, and the feeding box 7 is filled with colloid; a heating block 8 arranged on the side wall of the feeding box 7; a stirring shaft 9 rotating in the feeding box 7; a first pump body 23 connected to the outside of the feeding box 7; the first pump body 23 extends to the bottom side of the upper template 6 and is provided with a feeding port 10.

[0026] It should be noted that due to the uneven heating and low heat dissipation efficiency of the traditional RF module packaging device. The uneven temperature distribution during the heating process leads to uneven curing or stratification of the colloid. At the same time, the insufficient heat dissipation capacity makes it difficult to meet the heat dissipation requirements under high power and high density work, which easily leads to the problem of overheating and damage of the module. This solution ensures the smooth and accurate movement of the upper template 6 through the first packaging structure, thereby improving the packaging accuracy; secondly, the stirring function of the loading part ensures the uniform heating of the colloid, prevents curing or stratification, and provides high-quality colloid materials for packaging; furthermore, the efficient heat dissipation system constructed by the second packaging structure utilizes the coolant circulation and alternating cold water tank 14 strategy to effectively absorb and dissipate heat, protect the RF module from overheating damage, and ensure long-term reliability; finally, the design of the movable packaging seat 11 improves flexibility, adapts to the requirements of different processes, and ensures the accuracy of packaging alignment and the efficiency of the process.

[0027] Specifically, in this embodiment, the scheme mainly includes a base 1; a first packaging structure and a second packaging structure arranged on the base 1; when the RF module needs to be packaged, the first motor 20 drives the screw rod 3 to rotate stably in the assembly frame 2; the rotation of the screw rod 3 drives the lifting block 5 to perform vertical lifting movement under the precise guidance of the guide rod 4 through the threaded fit; this design not only ensures the stability of the lifting block 5 during the lifting process, but also improves the lifting accuracy of the lifting block 5 through the precise threaded fit and the guidance of the guide rod 4;

[0028] As the lifting block 5 rises and falls, the upper template 6 fixed at its bottom will also move accurately to the specified position to ensure the smooth progress of the packaging process and the packaging quality. In the loading part, the loading box 7 is pre-filled with an appropriate amount of colloid. The heating block 8 is arranged on the side wall of the loading box 7, and the colloid is heated to a temperature and fluidity suitable for the packaging operation to avoid poor fluidity or precipitation of the colloid due to too low temperature.

[0029] At the same time, the stirring shaft 9 rotates continuously in the feeding box 7, and the colloid is heated more evenly through the stirring action, and the colloid is prevented from solidifying or stratifying during the heating process; this stirring action ensures the uniformity and stability of the colloid, and provides a good material basis for subsequent packaging operations;

[0030] When the upper template 6 and the lower template 12 are combined to the predetermined position, the first pump body 23 draws the heated colloid out of the loading box 7; then, the colloid extends through the first pump body 23 to the feeding port 10 on the bottom side of the upper template 6 and is accurately transported to the surface of the RF module; at this time, the colloid is evenly applied to the surface of the RF module through the feeding port 10 to form a protective packaging layer.

[0031] In a further preferred embodiment of the present invention, Figure 1As shown, the second packaging structure includes: a packaging seat 11 sliding on the base 1; a lower template 12 is provided in the packaging seat 11, and a cooling groove 13 is provided between the lower template 12 and the packaging seat 11; cold water tanks 14 are provided at both sides of the assembly frame 2, and the cold water tanks 14 are filled with coolant; the outer sides of the two cold water tanks 14 are connected to the second pump body 15, and the other end of the second pump body 15 is connected to the cooling groove 13 through a flexible pipe 16.

[0032] In this embodiment, the second pump body 15 draws the coolant in the cold water tank 14 through the flexible pipe 16 and transports it to the cooling tank 13; in the cooling tank 13, the coolant flows freely and fully contacts the lower template 12, effectively taking away the heat generated during the packaging process of the RF module;

[0033] As the packaging process progresses, the RF module and its surrounding components will release a certain amount of heat; this heat is transferred to the lower template 12 by heat conduction, and then absorbed by the coolant in the cooling tank 13; the temperature of the coolant gradually increases during the process of absorbing heat, and in order to maintain its cooling efficiency, the two cold water tanks 14 are used alternately in sequence;

[0034] In addition, during the packaging process, the packaging seat 11 can slide to different positions along the base 1 as needed to adapt to the loading and unloading process or adjust the alignment position with the upper template 6; this design not only improves the flexibility of packaging, but also makes the entire packaging process more efficient and smooth.

[0035] In a further preferred embodiment of the present invention, Figure 1 As shown, an electric push rod 17 is disposed on the side of the assembly frame 2 opposite to the packaging seat 11 , and the telescopic end of the electric push rod 17 is connected to the side wall of the packaging seat 11 .

[0036] In this embodiment, through the precise control of the electric push rod 17, the packaging seat 11 can be easily moved to the desired position without manual pushing, thereby simplifying the operation process and reducing labor costs.

[0037] In a further preferred embodiment of the present invention, Figure 1 As shown, a guide groove 18 for the assembly frame 2 to slide is provided in the middle of the upper surface of the base 1 .

[0038] In this embodiment, the existence of the guide groove 18 not only provides a clear path for the movement of the assembly frame 2, but also limits the deviation and shaking of the assembly frame 2 through its structural characteristics, thereby ensuring the smooth progress of the entire packaging process and the stability of the packaging quality.

[0039] In a further preferred embodiment of the present invention, Figure 1As shown, heat dissipation fins 19 are provided on the outer side of the cold water tank 14 .

[0040] In this embodiment, the heat dissipation fins 19 on the outside of the cold water tank 14 can effectively release this part of heat into the surrounding environment, helping the coolant to cool down quickly so that it can be used again in the cooling process. This design not only improves the cooling efficiency, but also ensures the continuous and stable progress of the packaging process.

[0041] In a further preferred embodiment of the present invention, Figure 1 As shown, a first motor 20 is disposed at the top of the assembly frame 2 , and an output end of the first motor 20 is fixedly connected to an end key of the screw rod 3 .

[0042] In this embodiment, the first motor 20 is started and its rotational power can be directly transmitted to the screw rod 3 , thereby driving the screw rod 3 to perform rotational motion, thereby achieving precise sliding of the lifting block 5 on the assembly frame 2 .

[0043] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a second motor 21 is disposed at the top of the loading box 7 , and an output end of the second motor 21 is fixedly connected to an end key of the stirring shaft 9 .

[0044] In this embodiment, when the second motor 21 is started, its rotational power is transmitted to the stirring shaft 9 through the key connection, so that the material in the loading box 7 is fully stirred and mixed. This design not only improves the uniformity of material mixing, but also ensures the stability and consistency of the material during the packaging process.

[0045] In a further preferred embodiment of the present invention, Figure 1-4 As shown, temperature sensors 22 are provided in both the loading box 7 and the cooling tank 13 .

[0046] In this embodiment, the temperature sensor 22 (PT100) can understand the temperature changes of the colloid during the mixing process, ensure that the materials are mixed at an appropriate temperature, avoid overheating or overcooling to produce adverse effects on the quality of the materials, and at the same time, can monitor the temperature in the cooling tank 13 in real time to ensure that the temperature in the cooling tank 13 is always maintained within an appropriate range, which can not only improve the cooling efficiency, but also protect the RF module from the risk of overheating damage.

[0047] Working principle: During the packaging process of the RF module, first, when the packaging process is started, the first motor 20 directly transmits its rotational power to the screw rod 3, driving the screw rod 3 to rotate stably in the assembly frame 2; the rotation of the screw rod 3 guides the lifting block 5 to perform vertical lifting movement under the precise guidance of the guide rod 4 through precise thread matching; this design ensures the stability and accuracy of the lifting block 5 during the lifting process, so that the upper template 6 fixed at its bottom can be accurately moved to the predetermined position to merge with the lower template 12, laying the foundation for the smooth progress of the packaging process;

[0048] At the same time, the colloid in the loading box 7 is gradually heated to a temperature and fluidity suitable for packaging operation under the action of the heating block 8; the stirring shaft 9 is continuously rotated under the drive of the second motor 21, and the colloid is heated more evenly through the stirring action, and the colloid is effectively prevented from solidifying or stratifying during the heating process, thereby ensuring the uniformity and stability of the colloid;

[0049] When the upper and lower templates 12 are combined to the predetermined position, the first pump body 23 starts to work, extracting the heated colloid from the loading box 7 and extending it to the feeding port 10 at the bottom side of the upper template 6 through the pump body; the colloid is accurately transported to the surface of the RF module and evenly smeared on the RF module through the feeding port 10 to form a protective encapsulation layer;

[0050] During the packaging process, the RF module and its surrounding components will release heat. To dissipate heat effectively, the second pump body 15 transports the coolant in the cold water tank 14 to the cooling tank 13 through the flexible pipe 16. The coolant flows freely in the cooling tank 13 and fully contacts the lower template 12 to take away the heat generated during the packaging process. To maintain the cooling efficiency of the coolant, the two cold water tanks 14 are used alternately to ensure that the coolant is always kept at a low temperature.

[0051] In addition, the packaging seat 11 can slide along the base 1 as needed during the packaging process to adapt to the loading and unloading process or adjust the alignment position with the upper template 6; this design improves the flexibility and efficiency of packaging, making the entire packaging process smoother; the precise control of the electric push rod 17 makes the movement of the packaging seat 11 easy and fast, without the need for manual effort;

[0052] The guide groove 18 provides a clear path for the movement of the assembly frame 2 and limits the deviation and shaking of the assembly frame 2, thereby ensuring the stability and quality of the packaging process; the heat dissipation fins 19 on the outside of the cold water tank 14 effectively release the heat absorbed by the coolant into the surrounding environment, helping the coolant to cool down quickly so that it can be used again in the cooling process.
