Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a circuit board cleaning and drying device. Background Art

[0002] During the processing of circuit boards, there may be defective products during the processing. At this time, it is necessary to wash off the solder resist on the circuit boards and rework them instead of directly scrapping the circuit boards. After cleaning the circuit boards, they need to be dried.

[0003] Publication No. CN210832774U discloses a cleaning and drying device for circuit boards after processing, comprising a base, a first motor and a first belt, the right side of the base being fixedly connected to the left end of the first motor, the output end of the first motor being movably connected to one end of the first belt, the end of the first belt away from the first motor being movably connected to a large threaded rod, the end of the large threaded rod away from the base being movably connected to a top plate, the bottom end of the top plate being fixedly connected to the bottom end of the base, the top inner wall of the top plate being fixedly connected to a high-speed fan, the surface of the large threaded rod being threadedly connected to a transmission block, the left side of the transmission block being movably connected to a first rotating shaft, the fixed block of the first rotating shaft away from one end of the transmission block being fixedly connected to a placement frame, a small threaded rod being sleeved on the inside of the right side wall of the placement frame, the surface of the small threaded rod being threadedly connected to a mesh plate, the end of the upper mesh plate away from the small threaded rod being movably connected to a sliding rod, the two ends of the sliding rod being fixedly connected to the inside of the left side wall of the placement frame, the surface of the sliding rod being movably connected to a lower mesh plate, the end of the lower mesh plate away from the sliding rod being threadedly connected to the surface of the small threaded rod. Although the rotating placement frame of this cleaning and drying device also allows the circuit boards to be turned over during the drying process, allowing for even and rapid drying, it solves the problem of traditional dryers blowing hot air, which can overheat the surface of the circuit boards and subsequently damage the components on the circuit boards. However, during the processing of this cleaning and drying device, water dripping from the surface of the circuit boards is often not effectively collected and easily remains inside the device. This not only may damage the internal structure of the device, but also increases the difficulty of subsequent cleaning work. Therefore, improvements are needed. Utility Model Content

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] See also Figure 1-4The present utility model provides a technical solution: a circuit board cleaning and drying device comprising a housing 1 made of aluminum alloy, a lightweight material with excellent thermal conductivity, which facilitates heat dissipation. A hot air blower 2 is connected to the top surface of the housing 1 to supply hot air to the interior of the device for drying. A motor 3 is bolted to the side of the housing 1. This motor 3 rotates a placement frame 4, which holds the circuit board body 5. The output end of the motor 3 is connected to the placement frame 4 via a coupling, smoothly rotating the placement frame 4. The circuit board body 5 is positioned within the placement frame 4. To secure the circuit board body 5, an automatic clamping mechanism is designed within the placement frame 4. When the circuit board body 5 is placed in the placement frame 4, the tension of a tension spring 14 causes a handle 13 to move. The tension spring 14 can be made of high-strength stainless steel to ensure durability and stable tension output. The handle 13 is connected to a short rod 11 via a hinge, so that movement of the handle 13 drives the short rod 11 in a corresponding manner. The other end of the short rod 11 is fixed with a clamping block 12. The clamping block 12 is made of rubber material to increase the friction with the circuit board body 5, and the rubber particles 15 on its inner side are used to improve the stability during clamping. When the tension spring 14 pulls the handle 13, the clamping block 12 will tightly squeeze the circuit board body 5, thereby realizing automatic fixation of the circuit board body 5. The inner wall of the shell 1 is fixed with a bottom groove 6 by welding or bolting. The inner wall of the bottom groove 6 is designed with a slide rail, and the slider 7 is slidably connected to the bottom groove 6 by embedding the slide rail. The size of the bottom groove 6 matches that of the slider 7 to ensure that the slider 7 can slide smoothly in the bottom groove 6. The top surface of the slider 7 is fixed with a water collecting tray 8 by screws. The size of the water collecting tray 8 is adapted to the internal space of the shell 1 so as to effectively collect water dripping from the surface of the circuit board body 5.

[0025] See also Figure 1-4 The top surface of the water receiving tray 8 is also installed with an air guide plate 9 by bonding or screwing. The air guide plate 9 is designed to be an arc-shaped structure. This shape is conducive to redirecting the air blown out by the hot air blower 2 upwards, thereby improving the drying efficiency. The air guide plates 9 are symmetrically distributed on the top surface of the water receiving tray 8 to ensure the uniform distribution of hot air. The inner wall of the bottom groove 6 is also installed with protrusions 10 by bonding or screwing. The protrusions 10 are made of hard rubber material, which has a certain elasticity and can provide sufficient friction. The protrusions 10 are arranged at equal distances on the inner wall of the bottom groove 6. When the slider 7 slides into the bottom groove 6, the protrusions 10 can squeeze the slider 7, thereby limiting the position of the water receiving tray 8 and preventing it from moving during use.

[0026] Example 2

[0027] See also Figure 3-4A clamping mechanism is installed inside the placement frame 4. This clamping mechanism includes a short rod 11, which is inserted through the placement frame 4 and connected to the placement frame 4 via a sliding mechanism. Specifically, the short rod 11 can slide freely within the preset track of the placement frame 4, making it easy to adjust the clamping position as needed. A clamping block 12 is fixedly mounted on one end of the short rod 11, while a handle 13 is mounted on the other end. This arrangement allows the operator to easily control the clamping force and position. Notably, a tension spring 14 is also sheathed on the surface of the short rod 11. The tension spring 14 is an elastic element that generates a restoring force. One end of the tension spring 14 is fixedly connected to the placement frame 4, while the other end is connected to the handle 13. When the handle 13 is pulled, the tension spring 14 is stretched and generates a restoring force. This restoring force causes the clamping block 12 to adhere tightly to the circuit board body 5, achieving a secure clamping effect. To enhance clamping stability and protect the surface of the circuit board body 5, rubber particles 15 are also fixedly mounted on the surface of the clamping block 12. These rubber particles 15 are evenly distributed on the clamping block 12 , which not only increases the friction during clamping, but also buffers the clamping force to a certain extent, thereby preventing the circuit board body 5 from being damaged.

[0028] Working principle: Place the circuit board body 5 in the placement frame 4 and fix it, then the hot air blower 2 can dry the surface of the circuit board body 5, and at the same time, the motor 3 can also drive the placement frame 4 to rotate. When the placement frame 4 rotates, it can drive the circuit board body 5 to turn over, so as to evenly dry the circuit board body 5, and at the same time, the water receiving tray 8 can be used to collect water dripping from the surface of the circuit board body 5, thereby preventing water from remaining in the shell 1, and the wind guide plate 9 can be used to guide the wind. When the hot air blower 2 blows downward, the wind can be redirected upward by the wind guide plate 9, which can improve the drying efficiency, and when the water receiving tray 8 needs to be removed, the staff only needs to pull the water receiving tray 8 outward, and the water receiving tray 8 then drives the slide The block 7 slides out of the bottom groove 6, and when installing the water receiving tray 8, it is only necessary to align the slider 7 under the water receiving tray 8 with the bottom groove 6 and slide it in. At this time, the water receiving tray 8 can be installed, and the protrusions 10 provided can squeeze the slider 7, thereby limiting the position of the water receiving tray 8. In the utility model, the design of the air guide plate 9 allows the wind from the hot air blower 2 to be redirected upwards, which not only reduces the waste of heat, but also allows the hot air to circulate in the drying chamber, thereby improving the drying efficiency. The design of the water receiving tray 8 can effectively collect water dripping from the surface of the circuit board body 5 to prevent water from remaining inside the equipment. This not only protects the internal structure of the equipment, but also facilitates subsequent cleaning work. At the same time, the water receiving tray 8 can be easily installed and disassembled through the design of the slider 7 and the bottom groove 6. This greatly simplifies the daily maintenance and cleaning of the equipment. The staff only needs to easily pull the water tray 8 to complete the disassembly, which is convenient for cleaning and replacement. When installing the circuit board body 5, it is only necessary to put the circuit board body 5 into the placement frame 4. Then, due to the tension of the tension spring 14, the tension spring 14 can pull the pull handle 13 to move, and the pull handle 13 can then drive the short rod 11 to move, and the short rod 11 then drives the clamping block 12 to move until the clamping block 12 squeezes the circuit board body 5. At this time, the circuit board body 5 can be fixed to the placement frame 4, and the provided rubber particles 15 can also increase the friction during squeezing, thereby improving the fixing effect. The utility model can fix the circuit board body 5 by a simple putting-in action. The main body 5 can be automatically fixed in the placement frame 4 without the need for complicated screw fixation or other tedious steps, which greatly improves the installation efficiency. The tension of the tension spring 14 can automatically make the clamping block 12 tightly squeeze the circuit board body 5, realizing automatic fixation and reducing the uncertainty and error of manual operation. The design of the clamping block 12 can ensure that the position of the circuit board body 5 in the placement frame 4 is stable and will not shift or shake during the drying process, thereby ensuring the drying quality and safety of the equipment. By setting the rubber particles 15, the friction between the clamping block 12 and the circuit board body 5 is increased, further improving the stability and reliability of the fixation, and preventing the circuit board from sliding during the drying process.
