Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning device that is easy to use. Background Technology
[0002] Printed circuit boards (PCBs) are key components of electronic information products. As the carrier of electronic components and the hub of electrical connections, they construct complex and orderly circuit networks within electronic devices through the precise combination of materials such as substrates, copper foil, and solder resist layers. Given the PCB's central role in circuit design, cleaning and dust removal during use are particularly important.
[0003] The existing patent (publication number: CN219943925U) discloses "a portable circuit board cleaning device. A slot is provided on one side of the cleaning box. Positioning rollers are symmetrically positioned on the upper and lower sides of the cleaning box via support bars inside the slot. A plug-in frame is provided between the positioning rollers, and a clamping mechanism is provided within the plug-in frame. Drive screws are symmetrically positioned on both sides inside the cleaning box, and guide rods are symmetrically positioned on both sides of the drive screws. A moving strip is provided between the drive screws and guide rods, and a telescopic cleaning mechanism is provided on the moving strip. A dust suction mechanism is provided at the bottom inside the cleaning box. This utility model, by setting up a plug-in frame in conjunction with a vertical clamping mechanism, can vertically fix the circuit board. The cleaning mechanism on both sides, which can be raised and lowered, enables double-sided cleaning of the circuit board. The device is easy to carry and can clean multiple circuit boards simultaneously. The dust suction mechanism effectively collects and treats dust and debris swept onto the vertical surface, greatly increasing its practicality and making cleaning convenient and quick."
[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: most of the existing cleaning equipment cannot achieve seamless connection of cleaning operations, resulting in a lot of downtime during the cleaning process, low equipment utilization, and difficulty in effectively improving production efficiency. Secondly, the cleaning equipment uses the method of extending the side telescopic rod to make the bristles of the soft brush roller close to the surface of the circuit board for cleaning, which requires an additional control system and increases the overall cost of the equipment.
[0005] Therefore, those skilled in the art have provided a user-friendly cleaning device to address the problems mentioned in the background section. Utility Model Content
[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a user-friendly cleaning device. During the cleaning process, another lower fixing plate can be used in advance to prepare for the installation of circuit boards. After cleaning, the circuit boards can be quickly replaced, achieving seamless connection of cleaning operations and improving equipment utilization and production efficiency.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A user-friendly cleaning device includes a cleaning box and two connecting plates. Screws are rotatably mounted on both the front and rear ends of one side of the cleaning box. A motor is fixedly mounted on the upper end of one side of the cleaning box. Sliding plates are threadedly connected to the outside of the two screws. Multiple compression springs are fixedly mounted on opposite ends of the two sliding plates. Two vacuum pumps are fixedly mounted on the upper end of the cleaning box. A collection box is slidably mounted on the lower end of the cleaning box.
[0009] An unlocking block is slidably installed at the upper end of the cleaning box. Multiple first springs are fixedly installed at the lower ends of the two connecting plates. Two upper fixing plates are fixedly installed between the lower ends of the multiple first springs. Fixing holes are opened on one side of the upper end of the two connecting plates.
[0010] Furthermore, one of the two lead screws is fixedly mounted at the upper end of the motor output end, and a linkage mechanism is provided between the lower ends of the two lead screws. Two guide rods are fixedly mounted inside the cleaning box on the side away from the motor, and the two sliding plates are slidably mounted outside the two guide rods on the side away from the motor.
[0011] Furthermore, the output ends of the two vacuum pumps are respectively fixedly installed at the front and rear ends inside the cleaning box, the output ends of the two vacuum pumps are both installed at the top of the collection box, the input ends of the two vacuum pumps are each fixedly installed with a connecting pipe, the input ends of the two connecting pipes are each fixedly installed with a vacuum plate, and the multiple compression springs are respectively fixedly installed on opposite sides of the two vacuum plates.
[0012] Furthermore, each of the two dust collection plates has multiple guide posts fixedly installed at opposite ends. The guide posts are respectively sleeved inside multiple compression springs, and the opposite ends of the guide posts are slidably installed inside two sliding plates.
[0013] Furthermore, each of the two dust-collecting plates is rotatably equipped with a brush roller at one end opposite to the other, and the two brush rollers are positioned at the front and rear ends of the two upper fixed plates.
[0014] Furthermore, two lower fixing plates are slidably arranged inside the cleaning box at the lower end, and two fixing rods are fixedly arranged at the front end of each of the two lower fixing plates. The four fixing rods are respectively slidably arranged inside the front end of the two upper fixing plates. The two lower fixing plates are fixedly connected on opposite sides by bolts.
[0015] Furthermore, one of the two fixing holes is externally located at the lower end of the unlocking block, and a second spring is fixedly installed at the upper end of the unlocking block. The upper end of the second spring is fixedly installed at the upper end of one side inside the cleaning box.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model proposes a user-friendly cleaning device. When cleaning circuit boards, the lower fixing plate is first connected using bolts. Then, the circuit board to be cleaned is fixed between the upper and lower fixing plates. After the circuit board is installed, the lower fixing plate is pushed to slide into the cleaning chamber to a suitable position. At this time, the unlocking block will engage with the fixing hole to lock the connecting plate, effectively preventing the circuit board from loosening during subsequent cleaning and ensuring the stability of the cleaning process. During the cleaning process, the other lower fixing plate is idle. At this time, the other circuit board to be cleaned can be fixed between the upper and lower fixing plates to achieve cleaning. In the pre-processing stage, after the circuit board is cleaned, pull the unlocking block upwards to disengage it from the fixing hole. Then, push the lower fixing plate to allow the cleaned circuit board to slide out smoothly. At the same time, the uncleaned circuit board enters the predetermined position inside the cleaning box. At this point, under the action of the second spring, the unlocking block automatically embeds into the fixing hole in the uncleaned upper fixing plate, preparing for the next round of cleaning. While cleaning the circuit boards, the cleaned circuit boards can be easily removed, and the uncleaned circuit boards can be installed between the upper and lower fixing plates, achieving efficient connection of cleaning operations, improving equipment utilization and production efficiency, and saving time costs.
[0018] 2. This utility model proposes a user-friendly cleaning device. During cleaning, the motor is started by the controller. The output of the motor drives one of the lead screws to rotate. Through the cooperation of the synchronous pulley and synchronous belt in the linkage mechanism, the other lead screw rotates synchronously, causing the sliding plate to move up and down. The elastic force of the compression spring pushes the dust suction plate, making the brush roller closely adhere to the surface of the circuit board, thereby brushing up the attached dust and impurities. At the same time, the dust suction pump is started. Through the connecting pipe, it works in conjunction with the dust suction plate to suck up the brushed dust and transport it to the collection box via the dust suction pump. The compression spring and guide column can automatically adjust the pressure of the dust suction plate and brush roller on the circuit board according to the unevenness of the circuit board surface. This effectively removes dust and impurities while avoiding damage to the circuit board due to excessive pressure, ensuring cleaning effect while protecting the circuit board from damage.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figures 1-5 One embodiment provided by this utility model:
[0028] A user-friendly cleaning device includes a cleaning box 1 and two connecting plates 4. Screws 16 are rotatably installed at both ends of one side of the cleaning box 1. A motor 18 is fixedly installed at the upper end of one side of the cleaning box 1. Sliding plates 14 are threadedly connected to the outside of the two screws 16. Multiple compression springs 21 are fixedly installed at opposite ends of the two sliding plates 14. Two vacuum pumps 11 are fixedly installed at the upper end of the cleaning box 1. A collection box 2 is slidably installed at the lower end of the cleaning box 1.
[0029] One of the two lead screws 16 has its upper end fixedly mounted at the output end of the motor 18. A linkage mechanism 17 is provided between the lower ends of the two lead screws 16. Two guide rods 13 are fixedly mounted inside the cleaning box 1 on the side away from the motor 18. Two sliding plates 14 are slidably mounted outside the two guide rods 13 on the side away from the motor 18. The output ends of two vacuum pumps 11 are fixedly mounted at the front and rear ends inside the cleaning box 1, respectively. The output ends of both vacuum pumps 11 are located at the upper end of the collection box 2. Connecting pipes 10 are fixedly mounted at the input ends of both vacuum pumps 11. Two suction plates 19 are fixedly installed at the input ends of the two connecting pipes 10. Multiple compression springs 21 are fixedly installed on opposite sides of the two suction plates 19. Multiple guide posts 15 are fixedly installed on opposite sides of the two suction plates 19. Multiple guide posts 15 are respectively sleeved inside multiple compression springs 21. The opposite sides of multiple guide posts 15 are slidably installed inside two sliding plates 14. Brush rollers 20 are rotatably installed on opposite sides of the two suction plates 19. The opposite sides of the two brush rollers 20 are installed at the front and rear ends of the two upper fixed plates 7.
[0030] The upper part of the cleaning box 1 is slidably provided with an unlocking block 3, and multiple first springs 5 are fixedly provided at the lower ends of the two connecting plates 4. Two upper fixing plates 7 are fixedly provided between the lower ends of the multiple first springs 5. Fixing holes 6 are opened on one side of the upper end of the two connecting plates 4.
[0031] Two lower fixing plates 9 are slidably arranged inside the lower end of the cleaning box 1. Two fixing rods 8 are fixedly arranged at the front end of each of the two lower fixing plates 9. The four fixing rods 8 are slidably arranged inside the front end of the two upper fixing plates 7 respectively. The two lower fixing plates 9 are fixedly connected on opposite sides by bolts. One of the two fixing holes 6 is arranged outside the lower end of the unlocking block 3. A second spring 12 is fixedly arranged at the upper end of the unlocking block 3. The upper end of the second spring 12 is fixedly arranged at the upper end of one side of the cleaning box 1.
[0032] Specifically, when cleaning the circuit board, the lower fixing plate 9 is first securely connected with bolts. Then, the upper fixing plate 7 is slowly pushed upwards, allowing it to slide upwards along the outer wall of the fixing rod 8. During the upward sliding of the upper fixing plate 7, the first spring 5 connected to it is compressed, causing the first spring 5 to contract in the space between the upper fixing plate 7 and the connecting plate 4. Next, the circuit board to be cleaned is placed smoothly between the upper fixing plate 7 and the lower fixing plate 9. Then, the external force applied to the upper fixing plate 7 is slowly released. Under the action of gravity and the elastic force of the first spring 5, the upper fixing plate 7 slides downwards along the outer wall of the fixing rod 8, thereby achieving reliable clamping of circuit boards of different sizes. This completes the circuit board installation steps.
[0033] After the circuit board is installed, push the lower fixing plate 9 to make it slide smoothly inside the cleaning box. When the lower fixing plate 9 slides to the appropriate position, the unlocking block 3, under the elastic action of the second spring 12, accurately engages into the pre-set fixing hole 6 at the upper end of the connecting plate 4, thereby firmly locking the connecting plate 4 and effectively preventing the circuit board from becoming loose during the cleaning process, ensuring the stability of the cleaning work.
[0034] Next, the motor 18 is started via the controller. This is a mature and publicly available technology, therefore its specific structure and working principle will not be elaborated upon here. The output of the motor 18 drives one of the lead screws 16 to rotate. The linkage mechanism 17 consists of two synchronous pulleys and a synchronous belt. The two synchronous pulleys are internally fixed to the lower end of the lead screw 16, and both pulleys are meshed with the synchronous belt. Under the action of the synchronous pulleys and the synchronous belt in the linkage mechanism 17, the other lead screw 16 also rotates synchronously. During the rotation of the lead screw 16, the sliding plate 14, which is threadedly connected to it, moves vertically along the lead screw 16 under the limiting constraint of the guide rod 13. As the sliding plate 14 moves, the compression spring 21 applies a pushing force to the dust collection plate 19, causing the brush roller 20 to fit tightly against the surface of the circuit board. When the sliding plate 14 moves up and down, the brush roller 20 rolls on the surface of the circuit board, effectively brushing up the dust and impurities on the surface of the circuit board. At the same time, the dust collection pump 11 starts working and is connected to the dust collection plate 19 through the connecting pipe 10 with a corrugated pipe structure. The brushed dust is quickly sucked in and transported to the collection box 2 by the dust collection pump 11. The compression spring 21 and the guide column 15 cooperate with each other to automatically adjust the pressure applied to the circuit board by the dust collection plate 19 and the brush roller 20 according to the undulation of the circuit board surface, thereby ensuring the best cleaning effect.
[0035] During the cleaning process, the other lower fixing plate 9 is idle. At this time, push the upper fixing plate 7 upward to fix the other circuit board between the upper fixing plate 7 and the lower fixing plate 9 in the aforementioned manner. When the circuit board being cleaned is finished, pull the unlocking block 3 upward to disengage it from the fixing hole 6, and then release the connecting plate 4. Next, push the lower fixing plate 9 to allow the cleaned circuit board to slide out of the cleaning box. At the same time, the uncleaned circuit board will enter the cleaning box. At this time, the unlocking block 3 will automatically embed into the fixing hole 6 in the uncleaned upper fixing plate 7. In this way, the cleaned circuit board can be easily removed during the cleaning process. Subsequently, the uncleaned circuit board can be installed between the upper fixing plate 7 and the lower fixing plate 9 in the same way to achieve continuous cleaning operation. When all circuit boards are cleaned, slide the collection box 2 at the lower end of the cleaning box 1 to clean the dust and impurities inside, and make full preparations for the next cleaning work.
[0036] This cleaning equipment is designed with a dual circuit board installation and cleaning process. While cleaning one circuit board, the installation preparation of another circuit board can be carried out simultaneously. After cleaning is completed, it can be quickly switched to achieve continuous and uninterrupted cleaning operations, which improves the efficiency of circuit board cleaning and saves time costs. By sliding the upper fixing plate 7 on the fixing rod 8 and cooperating with the elastic action of the first spring 5, it can flexibly adapt to circuit boards of different sizes and specifications and clamp them stably. Whether it is a small precision circuit board or a large circuit board, it can be effectively cleaned on this equipment, thus expanding the scope of application of the equipment.
[0037] Motor 18 drives lead screw 16 to rotate, causing sliding plate 14 to move brush roller 20 up and down. During this movement, brush roller 20 closely adheres to the circuit board surface and rotates, thoroughly brushing away dust and impurities. Simultaneously, dust pump 11, through corrugated pipe 10 and suction plate 19, promptly sucks the dust stirred up into collection box 2, achieving simultaneous cleaning and vacuuming. This effectively avoids secondary dust pollution and ensures the cleanliness of the circuit board surface. The clever cooperation between compression spring 21 and guide post 15 allows suction plate 19 and brush roller 20 to automatically adjust pressure according to the unevenness of the circuit board surface. This adaptive adjustment function ensures that brush roller 20 and circuit board surface always maintain a constant pressure. Maintaining appropriate contact pressure effectively cleans the circuit board while preventing damage due to excessive pressure, thus improving the safety and reliability of the cleaning process. The design of the unlocking block 3 and the second spring 12 makes the installation and removal of the circuit board simple and quick, requiring only a simple pulling and releasing operation. At the same time, the way the unlocking block 3 snaps into the fixing hole 6 can firmly lock the connecting plate 4, preventing the circuit board from loosening during the cleaning process and ensuring the stability and reliability of the cleaning work. The collection box 2 adopts a sliding design, which can be easily slid out after cleaning, making it convenient to clean the dust and impurities collected inside. This makes the maintenance of the equipment simple and easy, reducing the maintenance cost and difficulty of use.
[0038] Furthermore, the first spring 5, the second spring 12, and the compression spring 21 are all made of stainless steel, which can prevent insufficient clamping force due to the decrease of elasticity after long-term use. The outer layer of the brush roller 20 is made of polyester fiber bristles and has been treated with antistatic agents, which can effectively prevent the static adsorption of dust. It should be noted that all components in this application, such as the compression spring 21, the first spring 5, the second spring 12, and the brush roller 20, are independently detachable. The contents not described in detail in this specification are prior art known to those skilled in the art.
[0039] Working principle: When cleaning the circuit board, first connect the lower fixing plate 9 with bolts. Then, push the upper fixing plate 7 upward so that it slides upward outside the fixing rod 8. When the upper fixing plate 7 slides upward, it will squeeze the first spring 5 connected to it, causing it to contract between the upper fixing plate 7 and the connecting plate 4. Next, place the circuit board between the upper fixing plate 7 and the lower fixing plate 9. Then, slowly release the force on the upper fixing plate 7 so that it slides downward along the outside of the fixing rod 8, thereby clamping circuit boards of different sizes and completing the installation of the circuit board. Then push the lower fixing plate 9 so that it slides inside the cleaning box. When it slides to the appropriate position, the unlocking block 3, under the action of the second spring 12, is locked into the fixing hole 6 at the upper end of the connecting plate 4, thereby locking the connecting plate 4 and preventing the circuit board from loosening during the cleaning process.
[0040] Next, the motor 18 is turned on by the controller, causing its output to drive one of the lead screws 16 to rotate. Through the synchronous pulley and synchronous belt in the linkage mechanism 17, the other lead screw 16 rotates synchronously. When the lead screw 16 rotates, the threaded sliding plate 14 moves up and down along the lead screw 16 under the limiting action of the guide rod 13. During the movement, the sliding plate 14 pushes the dust suction plate 19 through the compression spring 21, so that the brush roller 20 is in close contact with the surface of the circuit board. When the moving plate moves up and down, the brush roller 20 will rotate on the surface of the circuit board, thereby brushing up the dust and impurities on the surface of the circuit board. At the same time, the dust suction pump 11 is started, and the dust brushed up is sucked in through the connecting pipe 10 with the dust suction plate 19, which adopts a corrugated pipe structure, and transported to the collection box 2 by the dust suction pump 11. The cooperation of the compression spring 21 and the guide column 15 can automatically adjust the pressure of the dust suction plate 19 and the brush roller 20 according to the undulation of the circuit board surface to ensure the cleaning effect.
[0041] During the cleaning process, the other lower fixing plate 9 will be idle. At this time, by pushing the upper fixing plate 7 at its upper end upward, another circuit board is fixed between the upper fixing plate 7 and the lower fixing plate 9. After the circuit board is cleaned, pull the unlocking block 3 upward to disengage it from the fixing hole 6, release the connecting plate 4, and then push the lower fixing plate 9 to slide out the cleaned circuit board. The uncleaned circuit board will enter the cleaning box. At this time, the unlocking block 3 will be embedded in the fixing hole 6 in the uncleaned upper fixing plate 7. During the cleaning process, the cleaned circuit board can be taken out. Then, the uncleaned circuit board can be installed between the upper fixing plate 7 and the lower fixing plate 9. After cleaning, slide the collection box 2 at the lower end of the cleaning box 1 to clean the collected dust and impurities, preparing for the next cleaning.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
