Technical Field
[0001] This utility model relates to the field of circuit board processing technology, specifically to a circuit board protective agent spraying device with rapid drying function. Background Technology
[0002] Circuit boards are a common type of electronic device, also known as printed circuit boards. Circuit boards make circuits miniaturized and more intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. During the production and processing of circuit boards, it is often necessary to spray some protective agents on their surface to increase the waterproof, moisture-proof and antistatic properties of the circuit board surface, thereby increasing the service life of the circuit board.
[0003] In the prior art, after the protective agent is sprayed onto the surface of the circuit board, the surface of the circuit board is in a relatively wet state and cannot dry quickly, which makes it inconvenient to carry out the next processing operation and reduces the processing efficiency of the circuit board.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a circuit board protective agent spraying device with fast drying, so as to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] A circuit board protectant spraying device with rapid drying includes a processing table. A sliding groove is formed at the center of the surface of the processing table. A connecting rod is fixedly connected inside the sliding groove. A sliding block is sleeved on the outside of the connecting rod. A placement plate is fixedly connected to the top of the sliding block. A support frame is fixedly connected to the surface of the processing table near its edge. A connecting pipe is provided on the inner top wall of the support frame. A spray head is provided at the end of the connecting pipe. A connecting frame is fixedly connected to the rear of the surface of the processing table. A cylinder is provided on the top of the connecting frame. A connecting plate is fixedly connected to the end of the cylinder. A connecting sleeve is fixedly connected to the bottom of the connecting plate. A drying component is provided at the bottom of the connecting sleeve. The drying component includes a rectangular block. A limiting groove is formed on the bottom surface of the rectangular block. A motor is installed inside the limiting groove. A threaded screw is provided at the end of the motor. A guide block is sleeved on the outside of the threaded screw. A drive fan is movably mounted on the surface of the guide block. A spherical movable shaft is provided at the center of the top of the rectangular block, and the spherical movable shaft is located inside the connecting sleeve.
[0008] Preferably, threaded holes are provided at the four corners of the surface of the drive fan and the guide block, and fastening bolts are rotatably connected inside the threaded holes. The threaded structure allows the drive fan to be movably disassembled and assembled with the guide block, making it convenient for people to replace the drive fan. The assembly method of the threaded structure also ensures the stability of the drive fan after installation.
[0009] Preferably, a connecting post is fixedly connected to the side of the placement plate, and a grip handle is fixedly installed at the end of the connecting post. The surface of the grip handle has multiple sets of semi-circular grooves. By using the grip handle, people can quickly move the sliding block by grasping it and pushing it left and right, which facilitates operation.
[0010] Preferably, a docking post is fixedly connected to the center of both ends of the sliding block, and a docking hole is opened at the center of both ends of the inner wall of the sliding groove. Magnetic suction pieces are fixedly connected to the ends of the docking posts and the inside of the docking holes. With the docking posts, the sliding block will be inserted into the docking holes when it moves to both ends inside the sliding groove. Then, it will be connected by two sets of magnetic suction pieces, thus fixing the position of the sliding block and ensuring the stability during the spraying and drying steps.
[0011] Preferably, the inner top wall of the connecting frame is provided with a storage slot. The size of the rectangular block is slightly smaller than the storage slot. A baffle plate is hinged to the surface end of the storage slot via a damping hinge. A rubber sealing strip is fixedly connected to the inner edge of the baffle plate. Through the storage slot, the drying component will be retracted into it after the cylinder retracts. Then, the damping hinge drives the baffle plate to flip and close the storage slot to form a sealed space. This prevents dust from accumulating on the surface of the drying component when it is not in use. For example, the threaded screw and drive fan may become stuck and unable to move due to external dust, and the air outlet of the drive fan may be blocked, affecting the blowing effect. The rubber sealing strip further enhances the sealing effect and improves the dustproof effect.
[0012] Preferably, the inner side of the baffle plate is provided with an installation groove near the two side edges. A moisture-proof box is movably installed inside the installation groove. The moisture-proof box is filled with desiccant, and the surface of the moisture-proof box has multiple sets of ventilation holes. Through the moisture-proof box, the desiccant inside adsorbs water vapor molecules in the sealed space, thereby ensuring that the storage tank is in a dry state, avoiding damage to its internal parts due to moisture, and providing further protection for the drying component.
[0013] Preferably, the bottom of the moisture-proof box and the four corners inside the mounting slot are all fixedly connected with Velcro, and the sizes of the multiple sets of Velcro are matched with each other. Through the Velcro structure, the moisture-proof box can be quickly connected and assembled with the baffle, and the disassembly and assembly steps are relatively convenient.
[0014] Preferably, a protrusion is fixedly connected to the center of the surface of the moisture-proof box, and an anti-slip cloth is pasted to the surface of the protrusion. By setting the protrusion with the anti-slip cloth, people can easily remove the moisture-proof box from the cover by pinching it with their fingers and pulling it down.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. By using a drying component installed on the spraying equipment, the reciprocating movement of the drive fan blows air onto the circuit board workpiece, enabling the circuit board components coated with protective agent to dry quickly. This reduces the waiting time for subsequent processing steps of the circuit board and helps improve the processing efficiency of circuit board production. At the same time, the drying component can be flexibly adjusted in height and angle, making it convenient to dry the circuit board components from different positions, thus increasing the flexibility of the drying component in use.
[0017] 2. The storage slot allows the drying component to retract into itself after the cylinder retracts. The damping hinge then causes the baffle to flip and close, forming a sealed space. This prevents dust from accumulating on the surface of the drying component when it is not in use. Dust can cause the threaded screw and drive fan to jam and become immobile, and can also clog the fan vents, affecting airflow. The rubber sealing strip further enhances the sealing effect and improves dust prevention. The desiccant inside the moisture-proof box absorbs moisture molecules within the sealed space, ensuring the storage slot remains dry and preventing internal parts from becoming damp and damaged, thus providing further protection for the drying component.

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.
[0026] According to an embodiment of the present invention, a circuit board protective agent spraying device with rapid drying is provided.
[0027] Example 1;
[0028] like Figure 1-5 As shown, the circuit board protective agent spraying equipment with rapid drying according to an embodiment of the present invention includes a processing table 1. A sliding groove 4 is formed at the center of the surface of the processing table 1. A connecting rod 5 is fixedly connected inside the sliding groove 4. A sliding block 6 is sleeved on the outside of the connecting rod 5. A placement plate 7 is fixedly connected to the top of the sliding block 6. A support frame 2 is fixedly connected to the surface of the processing table 1 near the edge. A connecting pipe is provided on the inner top wall of the support frame 2. A spray head 3 is provided at the end of the connecting pipe. A connecting frame 8 is fixedly connected to the rear of the surface of the processing table 1. A spray head 3 is provided on the top of the connecting frame 8. A cylinder 10 is fixedly connected to a connecting plate at its end. A connecting sleeve is fixedly connected to the bottom of the connecting plate. A drying component 9 is provided at the bottom of the connecting sleeve. The drying component 9 includes a rectangular block 18. A limiting groove is provided on the bottom surface of the rectangular block 18. A motor 19 is provided inside the limiting groove. A threaded screw 20 is provided at the end of the motor 19. A guide block 21 is sleeved on the outside of the threaded screw 20. A drive fan 22 is movably mounted on the surface of the guide block 21. A spherical movable shaft is provided at the top center of the rectangular block 18, and the spherical movable shaft is located inside the connecting sleeve.
[0029] In this embodiment, threaded holes are provided at the four corners of the surface of the drive fan 22 and the guide block 21. Fastening bolts are rotatably connected inside the threaded holes. Through the threaded structure, the drive fan 22 can be movably disassembled and assembled with the guide block 21, making it convenient for people to replace the drive fan 22. The assembly method of the threaded structure also ensures the stability of the drive fan 22 after installation.
[0030] In this embodiment, a connecting column is fixedly connected to the side of the placement plate 7, and a grip handle is fixedly installed at the end of the connecting column. Multiple semi-circular grooves are opened on the surface of the grip handle. By using the grip handle, people can quickly move the sliding block 6 by grasping it with their hands and pushing it left and right, which facilitates people's operation.
[0031] In this embodiment, docking posts 23 are fixedly connected to the center of both ends of the sliding block 6, and docking holes are opened at the center of both ends of the inner wall of the sliding groove 4. Magnetic suction pieces are fixedly connected to the end of the docking post 23 and the inside of the docking hole. When the sliding block 6 moves to both ends inside the sliding groove 4, it will be inserted into the docking hole through the docking post 23. Then, it will be connected by the two sets of magnetic suction pieces, so that the position of the sliding block 6 is fixed, ensuring the stability during the spraying and drying steps.
[0032] In this embodiment, a storage slot 17 is provided on the inner top wall of the connecting frame 8. The size of the rectangular block 18 is slightly smaller than that of the storage slot 17. A baffle plate 11 is hinged to the surface end of the storage slot 17 via a damping hinge. A rubber sealing strip 12 is fixedly connected to the inner edge of the baffle plate 11. Through the storage slot 17, the drying component 9 will be retracted into its interior after the cylinder 10 retracts. Subsequently, the damping hinge drives the baffle plate 11 to flip and close the storage slot 17 to form a sealed space. This prevents dust from accumulating on the surface of the drying component 9 when it is not in use. For example, the threaded screw 20 and the drive fan 22 may become stuck and unable to move due to external dust, and the air outlet of the drive fan 22 may be blocked, affecting the blowing effect. The rubber sealing strip 12 further enhances the sealing effect and improves the dustproof effect.
[0033] In this embodiment, an installation groove 13 is provided on the inner side of the baffle plate 11 near the two side edges. A moisture-proof box 14 is movably installed inside the installation groove 13. The moisture-proof box 14 is filled with desiccant, and multiple sets of ventilation holes 15 are provided on the surface of the moisture-proof box 14. Through the moisture-proof box 14, the desiccant inside adsorbs water vapor molecules in the sealed space, thereby ensuring that the storage tank 17 is in a dry state and preventing the internal parts from being damaged by moisture, thus providing further protection for the drying component 9.
[0034] In this embodiment, Velcro is fixedly connected to the bottom of the moisture-proof box 14 and the four corners inside the mounting groove 13, and the sizes of multiple sets of Velcro are matched with each other. Through the Velcro structure, the moisture-proof box 14 can be quickly connected and assembled with the baffle 11, and the disassembly and assembly steps are relatively convenient.
[0035] In this embodiment, a protrusion 16 is fixedly connected to the center of the surface of the moisture-proof box 14, and an anti-slip cloth is pasted on the surface of the protrusion 16. By setting the protrusion 16 with the anti-slip cloth, people can easily remove the moisture-proof box 14 from the cover plate 11 by pinching it with their fingers and pulling it down.
[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0037] In practical applications, the circuit board is placed on the placement plate 7, and the spray head 3 above sprays a protective agent liquid onto its surface. After the spraying step is completed, the handle is grasped and pushed to the right, and the sliding block 6 slides on the connecting rod 5 until the sliding block 6 moves to the right end of the sliding groove 4. At this time, the docking post 23 will be inserted into the docking hole, and the sliding block 6 will be fixed by the two sets of magnetic adsorption plates. At this time, the circuit board is located directly below the connecting frame 8. At this time, the drying component 9 starts to operate. The driving fan 22, driven by the motor 19 and the threaded screw 20, moves back and forth in the limiting groove under the action of the guide block 21 to blow air onto the surface of the circuit board, so that the liquid protective agent on its surface dries quickly. The drying component 9 can move up and down under the action of the cylinder 10 and the ball joint. With adjustable angle operation, it offers greater flexibility during use. After the drying step is completed, the cylinder 10 retracts, causing the drying component 9 to be retracted into the storage tank 17. Subsequently, the damping hinge causes the baffle plate 11 to flip and close the storage tank 17, forming a sealed space. This prevents dust from accumulating on the surface of the drying component 9 when it is not in use. For example, the threaded screw 20 and the drive fan 22 may become stuck and unable to move due to external dust, and the air vent of the drive fan 22 may be blocked, affecting the blowing effect. The rubber sealing strip 12 further enhances the sealing effect and improves the dustproof effect. In addition, the desiccant box 14 absorbs moisture molecules in the sealed space through its internal desiccant, thereby ensuring that the storage tank 17 is in a dry state and preventing the internal parts from being damaged by moisture, thus providing further protection for the drying component 9.
[0038] In summary, by utilizing the above-mentioned technical solution of this utility model, the drying component 9 installed on the spraying equipment, driven by the reciprocating movement of the fan 22, blows air onto the circuit board workpiece, enabling the circuit board components coated with protective agent to dry quickly, reducing the waiting time for subsequent processing steps of the circuit board, and helping to improve the processing efficiency of circuit board production. Simultaneously, the drying component 9 can flexibly adjust its height and operating angle, facilitating drying of the circuit board components from different positions. Through the provided storage slot 17, the drying component 9 is retracted into the cylinder 10 after retraction, and then the damping hinge drives... The baffle 11 flips over and closes with the storage compartment 17 to form a sealed space, preventing dust from accumulating on the surface of the drying component 9 when it is not in use. For example, the threaded screw 20 and the drive fan 22 may become stuck and unable to move due to external dust, and the air vent of the drive fan 22 may be blocked, affecting the blowing effect. The rubber sealing strip 12 further enhances the sealing effect and improves the dustproof effect. In addition, the desiccant box 14 absorbs water vapor molecules in the sealed space through its internal desiccant, thereby ensuring that the storage compartment 17 is in a dry state and preventing the internal parts from being damaged by moisture, thus providing further protection for the drying component 9.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
