Description

Technical Field

[0001] This utility model relates to a drying device, and more particularly to a drying device and electronic component processing equipment. Background Technology

[0002] Electronic components often require thorough drying during production to remove moisture and ensure stable electrical performance. Current technology typically employs a heating chamber for drying electronic components. This method is generally carried out in an open environment, exposing the electronic components to heated air. By increasing the temperature, the surface of the components is heated, gradually evaporating moisture from the outside in.

[0003] However, this method is easily affected by factors such as ambient temperature, electronic component structure, and drying time during the heating process. Moisture inside the electronic components is difficult to completely evaporate, leading to insufficient drying and consequently affecting the parameter consistency and quality stability of the capacitor products. Furthermore, since the electronic components are mostly stationary during this drying process, uneven heating of different parts can also cause variations in drying effects, thus affecting the uniformity of the entire batch of products.

Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar attributes, not to indicate or imply relative importance or a specific order.

[0027] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0028] Please refer to Figure 1 This utility model provides a drying device comprising a first driving assembly 4, a first housing 1, a second housing 2, and a vacuum assembly 5 disposed on the first housing 1. The first housing 1 and the second housing 2 are arranged opposite to each other. The first driving assembly 4 is driven by the first housing 1 and is used to drive the first housing 1 to move along a horizontal direction or a preset trajectory, thereby achieving the approach and separation of the first housing 1 and the second housing 2, thus forming or opening a sealed space for accommodating electronic components 7. In this embodiment, the first driving assembly 4 can be a linear cylinder, which drives the first housing 1 to move quickly and smoothly by controlling changes in air pressure. It has a simple structure, fast response speed, and is suitable for automated control environments. Alternatively, a lead screw mechanism, a slide rail motor, or other linear drive devices can be used to achieve higher precision motion control and meet the requirements of different working conditions for speed, stroke, or positioning accuracy.

[0029] Specifically, the vacuum assembly 5 is connected to the first housing 1. After a sealed space is formed, the vacuum assembly 5 is activated to extract the air from the sealed space, bringing it into a vacuum or low-pressure state. Under vacuum conditions, the boiling point of water is significantly reduced, allowing water to evaporate rapidly from the inside of the electronic component 7, improving drying efficiency and reducing the risk of heat damage. The drying device also includes a second drive assembly 6 and a drying assembly 3 disposed inside the second housing 2. The second drive assembly 6 is connected to the drying assembly 3 and drives the drying assembly 3 to rotate during operation. In this embodiment, by clamping the electronic component 7 and making it rotate continuously during the drying process, the heating is more uniform, avoiding localized residual moisture, thereby improving drying consistency and overall product quality.

[0030] like Figure 2As shown, the drying assembly 3 includes a drive roller 31, a drive disk 32, and multiple clamps 33 arranged circumferentially along the drive disk 32. The drive roller 31 is connected to the second drive assembly 6 and rotates under the drive of the second drive assembly 6, thereby driving the drive disk 32 to rotate around its central axis. Multiple clamps 33 are evenly distributed on the drive disk 32, each clamp 33 including a support plate 34, a first clamping part 35, and a second clamping part 35. The support plate 34 is fixed to the drive disk 32 and is used to support the electronic component 7. The first clamping part 35 and the second clamping part 35 are arranged opposite each other and can rotate relative to the drive disk 32, thus moving closer or further apart to form a clamping area for clamping the electronic component 7. When the two clamping parts 35 move relative to each other and retract, they can firmly clamp the electronic component 7, preventing it from loosening or falling off during rotation; when the clamping parts 35 open, it facilitates the loading and unloading of the electronic component 7. The aforementioned clamp 33 structure allows multiple electronic components 7 to be simultaneously mounted on the drive disk 32, rotating with the drive disk 32 during the drying process. This structure not only improves the batch processing capacity of the drying process but also ensures uniform heating of each electronic component 7 through rotation.

[0031] Optionally, such as Figure 3 As shown, the first clamping part 35 and the second clamping part 35 are provided with transmission teeth 38 at their opposite ends, and the two clamping parts 35 are connected by the meshing of the transmission teeth 38. When one of the clamping parts 35 rotates around its rotation axis, the transmission teeth 38 drive the other clamping part 35 to rotate synchronously, thereby enabling the two clamping parts 35 to move closer or further away from each other around the clamping area. This structure simplifies the drive control logic, requiring only a single-point rotational force to achieve bilateral clamping action. The structure is compact and the linkage is reliable, which helps to improve the overall stability and clamping consistency of the fixture 33. During the clamping process, the meshing between the transmission teeth 38 also plays a role in limiting and transmitting torque, preventing the clamping part 35 from jamming on one side or rotating unevenly.

[0032] In this embodiment, the drying assembly 3 includes a rolling element disposed on the drive disk 32. The ends of the first clamping part 35 and the second clamping part 35 opposite to each other are movably connected to the rolling element via a rotating shaft. The rolling element serves as the central fulcrum when the clamping part 35 rotates. By rotating the clamping part 35 around the rolling element, the two clamping parts 35 can synchronously move closer to or further away from the clamping area, thereby clamping or releasing the electronic component 7.

[0033] Optionally, the rolling element can be a bearing structure, roller, or other low-friction component to reduce the motion resistance during the opening and closing of the clamp 33, and improve the flexibility and stability of the clamping action. This structure not only simplifies the opening and closing mechanism of the clamp 33, but also effectively controls the clamping trajectory, ensuring that the clamping area reliably wraps around the electronic component 7 when it closes, avoiding clamping eccentricity or uneven contact.

[0034] like Figure 3 As shown, the drying assembly 3 includes a positioning member 39 screwed onto the clamping portion 35. One end of the positioning member 39 passes through the clamping portion 35 and abuts against the rolling element, used to lock the clamping portion 35 after it rotates to the target position. Specifically, the positioning member 39 can be a screw, a pin, or a fastening member with a limiting structure. By tightening the positioning member 39, its end presses against the surface of the rolling element, restricting the rotation of the clamping portion 35 around the rolling element, thereby maintaining the stability of the opening and closing state of the clamp 33, preventing the clamp 33 from shifting angle due to vibration or load changes, and improving the clamping reliability of the clamp 33. At the same time, it also facilitates the adjustment of the clamping angle according to the external dimensions of the electronic component 7, enhancing the adaptability of the clamp 33.

[0035] Optionally, at least two clamping portions 35 are provided with a first vent 36 and a second vent 37. The vents extend along the thickness direction of the clamping portion 35 and are used to remove moisture from the surface of the electronic component 7 or the area around the clamping region during the drying process. The vents allow water vapor released by the electronic component 7 under high temperature or vacuum conditions to be quickly discharged from the clamping area, preventing moisture from accumulating inside the clamp 33 and thus reducing the impact of moisture on drying efficiency. Furthermore, this structure effectively reduces the backflow caused by steam condensation at the edges of the clamp 33, further improving the thoroughness and uniformity of drying, making it particularly suitable for processing electronic components 7 (such as electrolytic capacitor cores) where high dryness requirements are necessary.

[0036] In one embodiment, the second housing 2 is provided with a maintenance window 21 for maintaining, cleaning, or replacing parts of the drying assembly 3 during equipment downtime or when the machine is stopped. The maintenance window 21 is located on the side wall or top of the second housing 2, close to the drying assembly 3 area, allowing operators quick access to critical components. Specifically, a movable door 22 is provided on the outside of the maintenance window 21 to close it in non-maintenance mode, preventing heat loss or dust entry. The movable door 22 can be manually opened or closed, and in conjunction with a sealing structure, ensures a stable internal environment for the second housing 2 when closed. This structure facilitates regular inspection and maintenance of the drying assembly 3, reduces the number of disassembly steps, and shortens the maintenance cycle.

[0037] like Figure 1 and 4As shown, the second housing 2 is provided with an mounting part 23 and a locking part 24 for assembling and fixing the movable door 22. The movable door 22 includes a main body 222, a connecting part 221, and a locking part 223. The connecting part 221 is located at one end of the main body 222 of the movable door 22 and is installed on the mounting part 23 via a hinge, pivot, or other rotating connection structure, enabling the movable door 22 to rotate and open or close relative to the second housing 2. The locking part 223 is located at the other end of the main body 222 of the movable door 22, corresponding to the locking part 24 on the second housing 2. When the movable door 22 is closed, the locking part 223 engages with the locking part 24, stably locking the movable door 22 at the maintenance window 21. The locking structure can adopt various forms such as buckles, slots, and magnetic attraction to ensure good sealing and fixation under high temperature or negative pressure conditions, preventing the movable door 22 from being accidentally opened.

[0038] Optionally, the movable door 22 also includes a positioning post disposed on the latching portion 223 and an elastic element disposed between the latching portion 223 and the positioning post. The positioning post is connected to the latching portion 223 via the elastic element, which is a spring, rubber, or other elastic material, providing sufficient elastic force to push the positioning post outward, thereby making the positioning post tightly contact the locking portion 24 on the second housing 2 and fixing the position of the latching portion 223. When the movable door 22 is closed, the positioning post will automatically push the latching portion 223 to engage with the locking portion 24 due to the action of the elastic element, forming a firm engagement between the positioning post and the locking portion 24. This structure not only ensures the reliable locking of the movable door 22 and prevents accidental opening during operation, but also provides a certain buffering effect through the elastic element, reducing the impact force when opening and closing the movable door 22, improving the smoothness of operation and the service life of the door lock.

[0039] This utility model embodiment also provides an electronic component processing apparatus, including the drying device described in the above embodiment. This electronic component 7 processing apparatus utilizes the aforementioned drying device to dry the electronic component 7, effectively controlling temperature, humidity, and vacuum conditions to ensure that the electronic component 7 reaches the required drying standards during processing.

[0040] In this equipment, the drying unit is integrated into the production line or automated equipment, connecting with other production modules (such as component assembly, testing, packaging, etc.) to achieve a fully automated, batch drying process. By adjusting the temperature, vacuum level, and rotation speed in the drying unit, the equipment can provide customized drying solutions according to the needs of different types of electronic components, optimizing production efficiency and reducing product defect rates caused by insufficient or excessive drying.

[0041] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
