Description

Technical Field

[0001] The present invention relates to the technical field of circuit board drying, in particular to a circuit board drying device. Background Art

[0002] A circuit board is a substrate used to support and connect electronic components. It is a board made of insulating material covered with conductive material. These conductors form a path for connecting electronic components such as resistors, capacitors, integrated circuits, and other components. Circuit boards can also have multi-layer designs to accommodate more electronic components. Circuit boards play a vital role in electronic devices. They not only provide connections between electronic components, but also provide circuit protection and isolation functions. With the continuous development of electronic devices, the design and manufacturing technology of circuit boards are also constantly innovating to meet the growing demand.

[0003] However, after users have used the existing circuit board drying device, they found that the existing circuit board drying device still has the following defects:

[0004] 1. In existing circuit board drying devices, due to the openness of the factory operation site, the surface of the circuit board will be contaminated with dust and debris. In the existing technology, it is impossible to wipe and clean both the upper and lower surfaces of the circuit board at the same time. If the upper and lower surfaces of the circuit board cannot be cleaned simultaneously, residual dust, moisture or other contaminants will affect the normal operation of the circuit board, increasing the risk of circuit short circuits or other circuit failures. Incomplete cleaning will result in impurities with poor conductive or insulating properties remaining on the surface of the circuit board, increasing safety hazards of the circuit board and may cause safety issues such as leakage and electric shock. In addition, the inability to clean both the upper and lower surfaces simultaneously will increase cleaning time and cost, because each side needs to be cleaned separately, which increases the complexity and time consumption of cleaning.

[0005] 2. In existing circuit board drying devices, water stains on the surface of the circuit board are not wiped off during drying, which may result in water marks on the surface of the dried circuit board. The water marks will affect the appearance of the circuit board and reduce user satisfaction and trust in the product. Moisture will form a conductive path, which will cause a short circuit. In addition, the water marks contain salt or other corrosive substances. The long-term presence of them will cause metal corrosion on the surface of the circuit board, affecting the electrical performance and reliability of the circuit board. The water marks will also cause the insulation performance of the circuit board surface to deteriorate, thereby causing leakage or insulation failure between circuits. If the components on the circuit board are affected by the water marks, the performance of the electronic equipment will be damaged.

[0006] Therefore, the present invention proposes a circuit board drying device to remedy and improve the deficiencies of the prior art. Summary of the Invention

[0012] Furthermore, a rotating disk is fixedly connected to a side of the fan close to the heating wire, and a sliding frame is rotatably connected to a side of the rotating disk away from the fan. The interior of the sliding frame is slidably connected to a limit rod.

[0013] Furthermore, the bottom end of the rotating disk is rotatably connected to a rotating block, the side of the rotating block away from the limiting rod is fixedly connected to the inner wall of the frame, the top end of the limiting rod is rotatably connected to the side away from the fan with a swing block, and the outside of the swing block is slidably connected to a horizontal moving rod.

[0014] Furthermore, the outer surface of the horizontal moving rod is symmetrically and slidingly connected to two limit blocks, the wiping cotton is fixedly connected to the side of the horizontal moving rod away from the limit rod, the side of the horizontal moving rod away from the wiping cotton is fixedly connected to a connecting rod, and the end of the connecting rod away from the horizontal moving rod is fixedly connected to a sliding block.

[0015] Furthermore, the upper and lower ends of the sliding block are symmetrically slidably connected with upper and lower moving blocks, and the upper and lower moving blocks are slidably connected inside the frame. The side of the upper and lower moving blocks away from the connecting rod is fixedly connected with absorbent cotton, and the side where the two absorbent cottons are close to each other is fixedly connected with spring 1.

[0019] (3) Beneficial effects

[0020] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0021] 1. By setting a limit rod, a horizontal moving rod and a wiping cotton, the rotation of the fan will drive the rotating disk to rotate along the center of the fan. Since the other side of the rotating disk is rotatably connected to the sliding frame, and the sliding frame is slidably connected to the limit rod, the swing block fixed at the top of the limit rod slides inside the horizontal moving rod, and the wiping cotton is fixedly connected to the surface of the limit block, so that the horizontal movement of the horizontal moving rod will drive the wiping cotton to move, thereby achieving the effect of wiping the dust on the upper and lower sides of the circuit board at the same time. Cleaning the upper and lower sides of the circuit board at the same time can ensure that the dirt and impurities on the surface are fully removed, so that the entire circuit board surface can be thoroughly cleaned, thereby improving the cleaning effect. In addition, thoroughly cleaning the upper and lower sides can reduce the possibility of impurities with poor conductive or insulating properties remaining on the surface of the circuit board, reducing the occurrence of leakage and electric shock safety issues. Cleaning the upper and lower sides at the same time can save cleaning time and cost because there is no need to clean each side separately, thereby improving the efficiency and effect of the cleaning operation. Cleaning the upper and lower sides of the circuit board at the same time can also keep the surface of the circuit board neat and smooth, thereby improving the appearance of the product and enhancing user trust and satisfaction with the product.

[0022] 2. By providing a sliding block, an up-and-down moving block, absorbent cotton and a spring, the horizontal movement of the horizontal moving rod along the limit block will drive the connecting rod to move horizontally. Since the two absorbent cottons are fixedly connected to the side of an up-and-down moving block, and the middle of the two absorbent cottons is fixedly connected to the spring, when the horizontal moving rod performs horizontal reciprocating motion, the absorbent cottons will be urged to fit and separate from each other, thereby achieving the effect of absorbing the residual watermark after wiping. Drying the watermark can prevent moisture from forming a conductive path, thereby avoiding circuit short circuits and ensuring the electrical performance and safety of the circuit board. In addition, the watermark contains corrosive substances, and long-term presence will cause metal corrosion on the surface of the circuit board. By drying, the corrosive effect of moisture on the metal of the circuit board can be reduced. Drying the watermark can also prevent the insulation performance of the circuit board from deteriorating, reduce leakage and other safety hazards, and ensure the stability and reliability of the circuit board. Keeping the surface of the circuit board dry can prevent moisture from affecting the overall performance of electronic components and the circuit board, extending the service life of the equipment and keeping it in good condition.

[0023] 3. By providing a fan, heating wire, transmission trough and air outlet, when the fan rotates to generate wind, the wind will be transmitted to the surface of the heating wire through the inside of the frame, and then the cold air will be converted into hot air by the heating wire to heat the wind, and then sprayed toward the circuit board above through the air outlet, thereby achieving the effect of hot air drying of the circuit board. The hot air can quickly remove moisture from the surface of the circuit board, accelerate the drying process, save time and improve efficiency. The hot air can also effectively remove moisture, which helps to avoid corrosion of the metal part of the surface of the circuit board due to water oxidation. Hot air drying can ensure the insulation performance of the circuit board surface, reduce the risk of conductivity, and ensure circuit safety. Hot air drying can also avoid the influence of moisture on the circuit board and electronic components, which helps to maintain the reliability and stability of the equipment.

[0024] 4. By providing an anti-collision fixing block, a second spring and a movable handle, when the circuit board needs to be wiped and dried, the anti-collision fixing blocks at both ends are pulled outward to fix the circuit board between the two anti-collision fixing blocks, and then the circuit board is moved by the movable handle, so as to achieve the effect of fixing the circuit board before drying and wiping. Fixing the circuit board can prevent it from being accidentally moved or dropped during the wiping and drying process, thereby reducing the risk of damage. In addition, fixing the circuit board can make it easier for the operator to wipe and dry, thereby improving operational efficiency. By fixing the circuit board, the wiping and drying process can also be better controlled to ensure the accuracy and cleanliness of the operation. Fixing the circuit board can also reduce the risk of accidental injury caused by the movement of the circuit board during the wiping and drying process. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] As a preferred implementation in this embodiment, Figure 4 As shown, the fan 301 is fixedly connected to a rotating disk 302 on the side close to the heating wire 202, and the rotating disk 302 is rotatably connected to a sliding frame 303 on the side away from the fan 301. The sliding frame 303 is internally slidably connected to a limiting rod 304. Through the fan 301, wind can be generated to blow air to the circuit board.

[0042] As a preferred implementation in this embodiment, Figure 4 As shown, the bottom end of the rotating disk 302 is rotatably connected to a rotating block 314, and the side of the rotating block 314 away from the limiting rod 304 is fixedly connected to the inner wall of the frame 201.

The absorbent cotton 312 can absorb the residual water stains on the surface of the circuit board.

[0045] Compared with the existing technology, this device can wipe the dust on the surface of the circuit board. Since dust can cause connection problems between circuits, wiping can ensure the cleanliness of the circuit board surface, reduce the risk of circuit failure, and thus improve electrical performance. By wiping the circuit board, potential short circuit hazards can also be eliminated, thereby improving the reliability of the circuit board.

[0046] In other aspects, this embodiment also provides a mechanism for clamping a circuit board, such as Figure 1 - Figure 8 As shown, a clamping mechanism 400 is provided on the side of the circuit board body 100 away from the wiping and drying mechanism 300. The outer frame structure 200 includes a frame body 201, a heating wire 202 and an air outlet 204. The frame body 201 is provided on the outside of the circuit board body 100. The heating wire 202 is fixedly connected to the inner wall of the frame body 201. There are a plurality of air outlets 204, which are evenly opened at the top of the inner wall of the frame body 201. The frame body 201 is used to fix the device. The heating wire 202 is used to generate a heating effect for the wind. The air outlet 204 is used to dry the circuit board that is not completely dried. The clamping mechanism 40 0 includes an anti-collision fixing block 401, a second spring 403, and a movable handle 406. Two anti-collision fixing blocks 401 are provided, and the two anti-collision fixing blocks 401 are symmetrically and movably connected to the two ends of the circuit board body 100. The second spring 403 is provided in the middle of the two anti-collision fixing blocks 401. The movable handle 406 is provided on the side of the second spring 403 away from the circuit board body 100. The anti-collision fixing block 401 is used to fix the circuit board body 100. The second spring 403 is used to facilitate the anti-collision fixing block 401 to clamp circuit board bodies 100 of different sizes. The movable handle 406 is used to drive the anti-collision fixing block 401 to move.

[0047] As a preferred implementation in this embodiment, Figure 1 and Figure 8 As shown, a conveying groove 203 is provided inside the frame 201, an air outlet 204 is provided at the top of the conveying groove 203, two sliding grooves 205 are symmetrically provided inside the fan 301, a moving groove 206 is provided inside the frame 201, and a rod groove 207 is provided on the side of the frame 201 away from the fan 301. The fan 301 can be heated by generating wind through the heating wire 202.

[0048] In this embodiment, Figure 7 As shown, the anti-collision fixing block 401 is fixedly connected to a fixing bar 402 on one side close to the movable handle 406, and the second spring 403 is fixedly connected to the side where the two fixing bars 402 are close to each other. A telescopic rod 1 404 is provided inside the second spring 403. Through the anti-collision fixing block 401 and then the second spring 403, the corners of the circuit board can be clamped and protected.

[0049] like Figure 7 As shown, the two ends of the telescopic rod 1 404 are respectively fixedly connected to the side of the two fixed bars 402 close to each other, the side of the fixed bar 402 away from the anti-collision fixed block 401 is fixedly connected to the telescopic rod 2 405, and the movable handle 406 is fixedly connected to the middle part of the side of the telescopic rod 2 405 away from the fixed bar 402. By moving the handle 406, the movement of wiping the circuit board can be manually controlled.

[0050] Compared with the existing technology, this device can use hot air to dry the circuit board. The hot air can quickly remove moisture from the surface of the circuit board, accelerate the drying process, save time and improve efficiency. The hot air can also effectively remove moisture, which helps to prevent corrosion of the metal part of the circuit board surface due to water oxidation.

[0051] Working principle: Before using this device, the user can install a motor at the fan 301 so that the output shaft of the motor is fixedly connected to the central axis of the fan 301. The motor is started to provide rotational force for the fan 301. Then, the surface of the wiping cotton 308 is stained with an appropriate amount of board washing water. Then, the circuit board body 100 to be cleaned is fixed between the two anti-collision fixing blocks 401. The circuit board body 100 is fixed between the anti-collision fixing blocks 401 by the inward rebound force of the second spring 403. As a result, the entire device can be started for use.

[0052] When the device is in use, when the inlet fan 301 rotates, the rotation of the fan 301 will drive the rotating disk 302 to rotate around the center of the fan 301. Since the other side of the rotating disk 302 is rotatably connected to the sliding frame 303, the sliding frame 303 is internally slidably connected to the limiting rod 304, and the bottom of the limiting rod 304 is rotatably connected to the rotating block 314. Since the rotating block 314 is limited by the frame 201, the rotation of the fan 301 will drive the limiting rod 304 to move. Since the swing block 305 fixed at the top of the limiting rod 304 slides inside the horizontal moving rod 306, the movement of the limiting rod 304 will drive the horizontal moving rod 306 to move. The movable rod 306 moves horizontally under the limit of the limit block 307. Since the wiping cotton 308 is fixedly connected to the surface of the limit block 307, the horizontal movement of the horizontal movable rod 306 will drive the wiping cotton 308 to move. When the user slowly moves the fixed circuit board body 100 through the opening of the rod slot 207, the wiping cotton 308 will wipe the dust on the surface of the circuit board. Since dust can cause connection problems between circuits, wiping can ensure the cleanliness of the circuit board surface, reduce the risk of circuit failure, and thus improve electrical performance. By wiping the circuit board, potential short circuit hazards can be eliminated, thereby improving the reliability of the circuit board.

[0053] When the user controls the moving handle 406 to continue to slowly move the circuit board body 100 along the rod groove 207, when it moves to the position of the absorbent cotton 312, the horizontal movement of the horizontal moving rod 306 along the limit block 307 will drive the connecting rod 309 to move horizontally. Since the sliding block 310 fixedly connected to the side of the connecting rod 309 is slidably connected to the middle of the two upper and lower moving blocks 311, when the horizontal moving rod 306 drives the sliding block 310 to move forward, the upper and lower moving blocks 311 on the upper and lower sides will move away from each other. 312 are fixedly connected to the side of a vertical moving block 311, and a spring 313 is fixedly connected to the middle of the two absorbent cottons 312. Therefore, when the horizontal moving rod 306 performs horizontal reciprocating motion, it will cause the absorbent cottons 312 to stick to and separate from each other, thereby achieving the effect of absorbing the residual watermarks produced by wiping. Wiping the watermarks can prevent moisture from forming a conductive path, thereby avoiding circuit short circuits and ensuring the electrical performance and safety of the circuit board. In addition, the watermarks contain corrosive substances, and long-term presence will cause metal corrosion on the surface of the circuit board. By wiping, the corrosive effect of moisture on the metal of the circuit board can be reduced;

[0054] After wiping off the water stains on the surface, continue to slowly move the moving handle 406 to drive the circuit board body 100 to the top of the air outlet 204. When the fan 301 rotates under the drive of the motor to generate wind, the wind will be transmitted to the surface of the heating wire 202 through the inside of the frame 201, and then the heating wire 202 is started to heat the wind so that the cold air is converted into hot air, and then sprayed toward the circuit board above through the air outlet 204, thereby achieving the effect of hot air drying the circuit board. The hot air can quickly remove moisture from the surface of the circuit board, accelerate the drying process, save time and improve efficiency. The hot air can also effectively remove moisture, which helps to avoid corrosion of the metal part of the surface of the circuit board due to water oxidation. Compared with directly wiping the circuit board and blowing it with a hair dryer, it can be operated accurately, avoiding the problems of incomplete cleaning and uneven drying caused by manual operation by the user.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
