Description

Technical Field

[0001] The invention relates to the technical field of electronic component drying, in particular to a drying device for electronic component production and a drying process thereof. Background Art

[0002] Electronic components are usually electroplated. After the electroplating is completed, the components need to be cleaned to remove the salt solution and other electroplating products on the surface. After cleaning, the electronic components need to be dried and then packaged for transportation.

[0003] However, when drying existing electronic components, the electronic components are usually placed on a drying rack and then dried using a fan or natural air drying. This not only reduces the drying rate of the electronic components, but also causes the electronic components that are piled together to be incompletely dried, and some cleaning liquid still adheres to the surface of the electronic components, affecting their use.

[0004] For this purpose, the patent with publication number CN114353471A proposes a rapid drying device for electronic components. First, the electronic components are placed in a mesh cover and then dried in a drying box using a drying diversion component. During drying, the gas drives the transmission component to work, so that the transmission component drives the cover body rotating component and the drying component inside the cover body to work, thereby performing rotation drying. It can also transfer the blowing from one side to the other side through an air pump to perform double-sided blowing, but due to the high moisture content in the airflow after drying, the heat cannot be recovered, resulting in heat waste.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0040] Refer to the following Figure 1 - Fig.10 The present invention describes a drying device and a drying process for producing electronic components provided by an embodiment of the present invention.

[0041] On the one hand, the present invention provides a drying device for producing electronic components, including a heating mechanism 300 for generating heat and a storage mechanism 500, wherein the heating mechanism 300 includes an outer cover 310 and a heating cage 330 located in the outer cover 310, wherein the heating cage 330 can generate heat as a resistance wire when powered on, and the heat is gathered in the outer cover 310, and a venturi duct 320 is radially arranged outside the outer cover 310, and the heat carried by the external air flow when passing through the heating cage 330 can be ejected from the venturi duct 320, and in order to enable the ejected hot air to directly dry the electronic components, the storage mechanism 500 for storing the electronic components is arranged at the periphery of the outer cover 310, so that the hot air flow ejected from the venturi duct 320 can be directly sprayed onto the electronic components in the storage mechanism 500, and the electronic components are dried, thereby realizing direct drying of the electronic components.

[0042] Preferably, the outer cover 310 is set as a cylindrical structure, the Venturi duct 320 is located outside the cylindrical structure, and the storage mechanism 500 is arranged in a ring shape outside the outer cover 310, so as to expand the amount of the storage mechanism 500, realize 360° outward air jet, and increase the number of electronic components dried at a single time.

[0043] Therefore, since the electronic components are arranged on the periphery of the heating mechanism 300, the number of electronic components dried at a single time can be greatly increased, thereby improving the drying efficiency.

[0044] like Figure 1 and Figure 2 As shown, in order to achieve drying in a closed environment, a cover body 210 is also provided, and the heating mechanism 300 and the storage mechanism 500 are both located inside the cover body 210, so that the drying operation is carried out inside the cover body 210, avoiding the phenomenon of heat waste caused by hot air spreading outward after being ejected from the Venturi duct 320.

[0045] like Figure 1 and Figure 3 As shown, the reason why the pipe for ejecting hot air is set as the Venturi duct 320 is to use the Venturi duct 320 to recover the heat carrying moisture (the heat carrying moisture here refers to the hot air ejected from the Venturi tube passing through the electronic components and drying the electronic components. The hot air will accumulate between the electronic components and the cover body 210, and the Venturi duct 320 is used to recover this part of the accumulated hot air carrying moisture).

[0046] However, since the humidity of this part of accumulated hot air is relatively high, if the Venturi duct 320 is directly used to re-spray it onto the electronic components, it will affect the drying process. Therefore, in order to solve this problem, the drying device for electronic component production provided in an embodiment of the present invention is also provided with a dehydration mechanism 400 capable of dehydrating the recovered hot air with relatively high humidity.

[0047] Combination Figure 3 and Figure 4 As shown, the dehydration mechanism 400 mentioned above is located above the outer cover 310, and the dehydration mechanism 400 includes a wire mesh dehydrator 430 as a main dehydration component, and a recovery pipe 420 is installed on the air inlet side of the wire mesh dehydrator 430, and the recovery pipe 420 extends to between the storage mechanism 500 and the cover body 210, and the exhaust side of the wire mesh dehydrator 430 is fixedly connected to the negative pressure adsorption part of the Venturi air duct 320. When the Venturi air duct 320 sprays hot air, it can generate negative pressure and inhale air on the exhaust side of the wire mesh dehydrator 430, so that the recovery pipe 420 can inhale air from the position where the air with higher humidity accumulates. These airflows with higher humidity can be dehydrated by the wire mesh dehydrator 430 and re-enter the Venturi air duct 320 for spraying to dry the electronic components.

[0048] Therefore, the drying device for electronic component production provided by the embodiment of the present invention can recycle used hot air with high humidity, thereby improving heat utilization and avoiding heat waste. The present invention can also dehydrate the hot air with high humidity, thereby avoiding the situation where the drying effect is affected by the high humidity of the recycled hot air.

[0049] Preferably, dense air holes are opened on the recovery pipe 420 at the portion where hot air with high humidity accumulates, so that the recovery pipe 420 can recover air at all heights.

[0050] Combination Figure 3-Figure 6 As shown, in order to send outside air into the heating cage 330 so that the outside air can be heated by the heating cage 330, an air pipe 340 is also provided, and the lower end of the air pipe 340 is set as an air inlet, the air inlet should be connected to the air pump, and the air inlet and the exhaust port of the air pump should be rotatably connected, and the air pipe 340 has air holes 341 along the radial direction. The air pipe 340 is preferably located on the axis of the heating cage 330, so that the airflow exhausted from the air pipe 340 can be sprayed onto the heating cage 330 more evenly, so that the heat on the heating cage 330 is evenly taken away by the airflow.

[0051] Combination Figure 3 , Figure 5 and Figure 6As shown, since the moisture on the hot air sucked by the recovery pipe 420 will flow on the wire mesh dehumidifier 430, its dehydration capacity will gradually decrease with the drying time. In order to solve this problem, the wire mesh dehydrator 430 in the prior art can be modified, and the wire mesh dehydrator 430 is divided into an upper layer and a lower layer. The upper layer and the lower layer both include a wire mesh body 432. The middle part of the wire mesh body 432 of the upper and lower layers is provided with a wrapping inner ring 434, and the wire mesh body 432 is axially provided with a heat-conducting column 450 integrated with the air pipe 340, the heat-conducting column 450 is located in the wrapping inner ring 434, and the outside of the wrapping inner ring 434 is provided with a heating evaporator 451. The heat on the air pipe 340 and the heating cage 330 can be transferred to the wire mesh body 432 through the heat-conducting column 450 and the heating evaporator 451, so that the water on the wire mesh body 432 can be quickly heated to evaporate the moisture thereon, thereby ensuring its dehydration capacity.

[0052] In addition, the above-mentioned heat-conducting column 450 is a solid structure, which is integrally formed with the air pipe 340, and both are made of metal materials, such as stainless steel, and the heat-conducting column 450 and the wrapped inner ring 434 should be rotatably connected through a bearing.

[0053] Under normal circumstances, the heating evaporator 451 is generally a heat-conducting metal, but since the wire mesh body 432 is generally made of polypropylene, the metal layer is prone to overheating, causing the polypropylene material to produce a burnt or scorched smell. Therefore, the heating evaporator 451 here includes a metal layer and a ceramic layer wrapped in the metal layer. The metal layer is used to receive heat from the wrapped inner ring 434, and the ceramic layer can effectively isolate the wire mesh body 432 and the metal layer. The ceramic layer is used to directly contact the metal layer with the wire mesh body 432, and no burnt or scorched smell will be produced.

[0054] The preferred heating evaporator 451 is radial, annular or mesh-shaped consisting of multiple concentric circles.

[0055] In fact, in addition to the above structure, the wire mesh water remover 430 should also include a wrapped outer ring 431. There are two groups of wrapped outer rings 431. A single group of wrapped outer rings 431 is wrapped on the corresponding wire mesh body 432. A ceramic grille 433 for maintaining the shape of the wire mesh body 432 should also be provided on the wrapped outer ring 431. The reason why the ceramic grille 433 is made of ceramic material instead of metal is to avoid the polypropylene material from producing a burnt smell or burning due to high-temperature metal. Of course, the corresponding wrapped outer ring 431 and the wrapped inner ring 434 should also be attached with a ceramic layer at the contact parts with the wire mesh body 432.

[0056] Therefore, the drying device for electronic component production provided by the embodiment of the present invention can ensure the long-term dehumidification effect of the wire mesh dehumidifier 430 when dehumidifying the recovered hot air, and further prevent the moisture in the hot air from returning to the Venturi duct 320.

[0057] Combination Figure 3-Figure 6 As shown, the above-mentioned water removal mechanism 400 also includes a fixed bucket 410 fixed on the top of the outer cover 310, the wire mesh water remover 430 is fixed in the fixed bucket 410, and a rotating cover 440 is rotatably installed on the upper part of the fixed bucket 410, that is, the rotating cover 440 and the fixed bucket 410 are connected by a bearing, and are equipped with corresponding sealing rings to improve the airtightness of the space formed by the rotating cover 440 and the fixed bucket 410, and reduce the leakage of the recovered hot air in the rotating cover 440.

[0058] In addition, the upper end of the heat-conducting column 450 is fixedly connected to the rotating cover 440, and one end of the recovery pipe 420 is fixed on the rotating cover 440; therefore, when the air pipe 340 rotates, it can drive the rotating cover 440 to rotate, and when the rotating cover 440 rotates, it can drive the recovery pipe 420 to move together. The rotating recovery pipe 420 can reach various locations where air with higher humidity gathers for recovery, thereby improving the uniformity of recovery.

[0059] like Figure 3 and Figure 4 As shown, the preferred venturi ducts 320 are arranged in a spiral shape on the outer surface of the outer cover 310 along the axial direction of the outer cover 310, thereby reducing the number of venturi ducts 320 while ensuring that electronic components at each height can receive the hot air flow.

[0060] In fact, to achieve the adsorption effect, the Venturi air duct 320 has a reducing portion 321 , and a negative pressure tube 322 is fixed between the reducing portion 321 and the inner cavity of the fixed bucket 410 , so that the reducing portion 321 can generate negative pressure at the negative pressure tube 322 , and the negative pressure tube 322 can absorb air through the recovery tube 420 .

[0061] During the use of the equipment, if the humidity in the cover body 210 is too high (that is, the humidity of the electronic components is too high), the temperature is too low (the temperature inside the equipment is low when the whole machine is just starting to run), or the humidity in the fixed bucket 410 is too high (the heating evaporator 451 cannot eliminate the moisture in the wire mesh dehydrator 430 in time), then the recycling operation should no longer be performed. Therefore, a humidity sensor is provided in the fixed bucket 410, and a humidity sensor is provided on the inner wall of the cover body 210. The humidity sensor is used to monitor the humidity in the fixed bucket 410, and the temperature sensor is used to detect the temperature in the cover body 210, and an electromagnetic valve is installed on the negative pressure pipe 322.

[0062] In specific implementation, when the temperature sensor detects that the temperature of the recovered air flow does not reach the preset temperature, the controller controls the solenoid valve to close, and the recovery operation is no longer performed; when the humidity sensor detects that the humidity of the recovered air flow is too high and has exceeded the preset humidity, the controller controls the solenoid valve to close, and the recovery operation is no longer performed.

[0063] The above-mentioned low temperature situation refers to the low temperature inside the equipment when the whole machine just starts to operate. At this time, if the airflow with a lower temperature is recovered, it will affect the drying effect of the equipment. As the drying proceeds, the temperature inside the cover body 210 gradually rises, and the controller controls the solenoid valve to close.

[0064] Therefore, the drying device for electronic component production provided by the embodiment of the present invention can automatically adjust whether to recycle hot air according to the temperature and humidity in the equipment, thereby avoiding the situation where the drying progress is affected due to insufficient heat or excessive humidity of the recycled hot air.

[0065] like Figure 1 and Figure 2 As shown, the drying device for producing electronic components provided by the embodiment of the present invention further includes a base 100, and a cover 210 is covered on the base 100, thereby forming a closed space for performing drying operations.

[0066] In order to dry the electronic components on the storage mechanism 500 better and more evenly, a rotating tray 700 for driving the electronic components on the storage mechanism 500 to rotate is rotatably installed on the upper surface of the base 100, and the storage mechanism 500 is installed on the rotating tray 700, so as to perform the drying operation evenly.

[0067] like Figure 1 , Figure 7 , Fig. 9 and Fig.10 As shown, the storage mechanism 500 mentioned above includes storage baskets 510 for storing electronic components arranged side by side in an upper and lower manner, an assembly plate 520 is fixed below the storage basket 510, and multiple assembly plates 520 are fixedly connected by connecting columns 540. A rotating shaft 550 is fixed on the lower end surface of one of the lower assembly plates 520, and the rotating shaft 550 is installed on the rotating tray 700. Multiple electronic components can be stored in multiple storage baskets 510. When the rotating tray 700 rotates, the storage baskets 510 can be driven to revolve around the center of the rotating tray 700, thereby improving the uniformity of drying.

[0068] In addition, in order to fix the position of the outer cover 310 , a support 311 is fixedly provided at the lower end of the outer cover 310 , and the lower end of the support 311 is fixed on the base 100 to ensure that the position of the outer cover 310 is stable.

[0069] like Figure 7 and Fig.10 As shown, since the airflow ejected from the Venturi duct 320 is unidirectional, it can only dry one side of the electronic components. Especially for plate-shaped electronic components such as circuit boards, the disadvantage of one-sided drying is more obvious. Therefore, a gear 530 is fixedly provided on the periphery of an assembly plate 520 below, and an arc-shaped tooth portion 560 is fixed on one side of the upper surface of the base 100. When the gear 530 passes through the arc-shaped tooth portion 560, it can engage with the arc-shaped tooth portion 560 to make the storage basket 510 flip along the rotating shaft 550, that is, whenever the storage basket 510 passes through the arc-shaped tooth portion 560, the gear 530 will roll along the arc-shaped tooth portion 560, thereby realizing the flipping of the storage basket 510, and then the other side of the electronic components can be aligned with the incoming wind direction to achieve double-sided drying.

[0070] It is worth noting that the ratio of the number of teeth of the gear 530 and the arc-shaped tooth portion 560 should be 1:0.5, so that the gear 530 can rotate 180° when passing through the arc-shaped tooth portion 560 .

[0071] Combination Figure 7-Figure 10 As shown, in order to facilitate the installation of the storage basket 510, the storage basket 510 includes a hollow basket 511 and a support 512 for supporting the hollow basket 511 on the assembly plate 520; however, since the storage basket 510 in the prior art is mostly a rectangular basket, the electronic components are generally placed flat when located inside the storage basket 510, so the contact area between the bottom surface of the storage basket 510 and the electronic components is relatively large, which affects the bottom drying, so the hollow basket 511 is a conical structure or a V-shaped structure, that is, its bottom does not contact the electronic components, reducing the area covered by the bottom surface of the electronic components, thereby improving the bottom drying efficiency.

[0072] Since the hollow basket 511 in the prior art is a metal mesh, and the metal mesh is heated at a high temperature, hot spots will be formed on the electronic components, thus affecting the performance of the electronic components. Therefore, the hollow basket 511 is set to a ceramic material here, and the ceramic is formed into a mesh structure, so that the ceramic is in direct contact with the electronic components, the temperature is evenly dispersed, the formation of hot spots on the electronic components is eliminated, and the performance of the electronic components is guaranteed.

[0073] like Figure 2 In order to prevent the bottom of the cover body 210 from overheating due to air leakage and affecting the operation of the staff, a sealing ring is installed on the lower end surface of the cover body 210, and a pressure relief valve 240 is installed on one side of the cover body 210 to prevent the air pressure in the cover body 210 from being too high.

[0074] Since the staff is required to load the electronic components into the hollow basket 511 , a support frame 220 is also provided here. The support frame 220 is located on one side of the cover body 210 , and a telescopic structure 230 is installed above the support frame 220 . The lower end of the piston rod of the telescopic structure 230 is fixedly connected to the cover body 210 .

[0075] In this embodiment, when the telescopic structure 230 is shortened, the cover 210 can be lifted upward to expose the storage basket 510 for easy loading.

[0076] Optionally, the telescopic structure 230 is a cylinder, a hydraulic cylinder or an electric telescopic rod.

[0077] Since the air pipe 340 needs to rotate and the rotating tray 700 also needs to rotate, a driving mechanism 600 for driving the rotating tray 700 and the air pipe 340 to rotate relative to each other is provided in the base 100 .

[0078] like Figure 3 In order to facilitate the driving of the rotating tray 700 , an integral extension shaft 710 is provided at the lower end of the rotating tray 700 , and the lower end of the air pipe 340 extends to below the extension shaft 710 .

[0079] The driving mechanism 600 includes a driven umbrella wheel 640 fixed on the extension shaft 710, a driven umbrella wheel 630 fixed on the lower end of the air pipe 340, an active umbrella wheel 620 meshed between the driven umbrella wheel 630 and the driven umbrella wheel 640, and a motor 610 for driving the active umbrella wheel 620 to rotate.

[0080] In this embodiment, when the motor 610 is working, the active umbrella wheel 620 can drive the driven umbrella wheel 1 630 and the driven umbrella wheel 2 640 to rotate relative to each other, thereby realizing the relative rotation of the rotating tray 700 and the air pipe 340.

[0081] The outer cover 310 and the support 311 are in a fixed and non-rotating state. The support 311 should be located between the air pipe 340 and the extension shaft 710, and its lower end should be fixed in the base 100 to keep it in a fixed and motionless state.

[0082] On the other hand, the present invention also provides a process for drying electronic components using the above-mentioned drying device for producing electronic components, comprising the following steps:

[0083] S1, lift the cover 210 upward to expose the storage mechanism 500, and place the electronic components to be dried in the storage basket 510;

[0084] S2. External airflow is sent into the air pipe 340 through the air pump or the fan, and is sprayed onto the electronic components in the storage basket 510 through the air holes 341 and the venturi air pipe 320, and the electronic components are dried. The used hot air carries moisture and moves to the space between the storage basket 510 and the inner wall of the cover 210 for storage, and is dehydrated by the wire mesh dehumidifier 430 and then recycled into the venturi air pipe 320 for reuse.

[0085] S3, the driving mechanism 600 drives the storage basket 510 to revolve, and the gear 530 and the arc-shaped tooth portion 560 drive the storage basket 510 to rotate, so as to drive the storage basket 510 to flip, so that the Venturi air duct 320 dries the other side of the electronic components.

[0086] When in use (when working), the operator places the electronic components one by one in the hollow basket 511 by lifting the cover body 210, and then lowers the cover body 210 to perform the drying operation.

[0087] During drying, the heating cage 330 can be heated through the belt, and the air pump can transport the external airflow into the heating cage 330 through the air pipe 340. The airflow carrying the heat from the heating cage 330 can be sprayed onto the electronic components through the Venturi duct 320 to dry the electronic components. The hot air carrying moisture accumulates in the inner wall area of ​​the cover body 210. When the heat passes through the Venturi duct 320, it can absorb air through the recovery pipe 420 and transport the airflow to the position of the wire mesh dehumidifier 430 for dehydration. The hot air after dehydration returns to the Venturi duct 320 for reuse.

[0088] During the drying process, the driving mechanism 600 can also drive the rotating tray 700 and the air pipe 340 to rotate, thereby achieving the purpose of uniform drying and uniform recovery.
