[0001] This utility model relates to the field of circuit board cleaning technology, and in particular to a circuit board surface cleaning device. Background Technology
[0002] In the production and maintenance of circuit boards, surface cleaning is a crucial step in ensuring their stable performance. Currently, ultrasonic cleaning equipment is commonly used in the industry for cleaning circuit boards. Ultrasonic cleaning, with its highly efficient stain removal capabilities, can effectively remove solder residue, dust, oil, and other impurities from the surface of circuit boards, and has been widely used in the electronics manufacturing field. However, after cleaning circuit boards, existing ultrasonic cleaning devices often leave a lot of water stains on the surface of the circuit boards. These water stains are usually wiped off with towels or paper towels. However, the surface of the circuit board is covered with a large number of delicate electronic components and delicate lines. During the wiping process, towels or paper towels may scratch the electronic components, causing components to fall off, lines to break, and other damage. At the same time, it is difficult to precisely control the force applied during wiping. Excessive force may directly cause the circuit board to deform. In addition, towels and paper towels may also generate debris during use, which may adhere to the surface of the circuit board. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the possibility of towels or paper towels scratching electronic components during wiping, and to provide a circuit board surface cleaning device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a circuit board surface cleaning device, comprising a main body, a support plate fixedly connected to one side of the main body, a lower pressure plate provided on the top of the support plate, absorbent cotton movably connected to the outer surface of the support plate through a groove, a support rod fixedly connected to the outer surface of the support plate, a collection box provided at the bottom of the support plate, a push rod provided on one side of the collection box, a fixed frame fixedly connected to the bottom of the support plate, a moving groove opened at the bottom of the lower pressure plate, a spring fixedly connected to the inner wall of the moving groove, locking spring pieces fixedly connected to both sides of the collection box, limit pieces fixedly connected to both sides of the push rod, and a collection port opened at the bottom of the support plate.

[0018] 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. Example
[0019] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a circuit board surface cleaning device, including a main body 1, a support plate 2 fixedly connected to one side of the main body 1, a lower pressure plate 3 provided on the top of the support plate 2, the bottom of the lower pressure plate 3 being movably connected to the top of the support plate 2 via a support rod 6 and a spring 13, absorbent cotton 4 being movably connected to the outer surface of the support plate 2 via a groove, a support rod 6 being fixedly connected to the outer surface of the support plate 2, a collection box 7 being provided at the bottom of the support plate 2, both sides of the collection box 7 being attached to the bottom of the support plate 2 via snap-fit springs 14, a push rod 10 being provided on one side of the collection box 7, and the top of the collection box 7 being snap-fitted... The fixed frame 11 is attached to the inner wall of the fixed frame 11, the engaging spring 14 engages with the inner wall of the sliding groove, the fixed frame 11 is fixedly connected to the bottom of the support plate 2, the sliding groove is opened on both sides of the fixed frame 11, the fixed frame 11 and the collection box 7 are both set at the bottom of the collection port 16, the push rod 10 moves in the inner wall of the sliding groove, the moving groove 12 is opened at the bottom of the lower pressure plate 3, the spring 13 is fixedly connected to the inner wall of the moving groove 12, the bottom of the spring 13 is fixedly connected to the top of the support rod 6, the engaging spring 14 is fixedly connected to both sides of the collection box 7, the limit piece 15 is fixedly connected to both sides of the push rod 10, and the collection port 16 is opened at the bottom of the support plate 2.
[0020] In this embodiment, a support plate 2 and a lower pressure plate 3 are provided to facilitate the placement of absorbent cotton 4 inside them. External force is applied to bring the support plate 2 and the lower pressure plate 3 closer together, thereby clamping them onto the upper and lower surfaces of the circuit board. This allows the circuit board, after being cleaned in an ultrasonic cleaner, to absorb most of the water stains on its surface into the absorbent cotton 4. A support rod 6 and a moving groove 12 are provided to facilitate the support of the lower pressure plate 3 on the upper end of the support plate 2. A spring 13 is provided to press the lower pressure plate 3 against the outer surface of the support rod 6. After the water absorption is completed, the pressure is released. After the pressure is applied to plate 3, spring 13 automatically rebounds, resetting the lower pressure plate 3. A collection box 7 is provided to collect the clean water falling from the collection port 16 through the absorbent cotton 4. The top of the collection box 7 is secured in the sliding grooves on both sides of the fixing frame 11 by a snap-fit spring 14. A push rod 10 is provided to push the snap-fit spring 14 away from the sliding groove, making it easy to remove the collection box 7 and pour out the water. A limiting piece 15 is provided, and sliding grooves matching the limiting piece 15 are provided on both sides of the sliding groove to limit the movement of the push rod 10. Example
[0021] like Figure 3 As shown, a fixing button 5 is provided on the outer surface of the lower pressure plate 3, and a fixing spiral pin 8 is fixedly connected to the bottom of the fixing button 5. A fixing opening 9 is provided on the top of the lower pressure plate 3, and the fixing button 5 is located on the top of the fixing opening 9.
[0022] In this embodiment, by setting a fixing button 5 and a fixing spiral needle 8, the absorbent cotton 4 inside the lower pressure plate 3 is fixed to the bottom end of the lower pressure plate 3, thereby reducing the possibility of the absorbent cotton 4 falling. The fixing spiral needle 8 passes through the fixing hole 9 through the fixing button 5 at the top. The tip of the fixing spiral needle 8 is relatively sharp, so it can easily be inserted into the absorbent cotton 4 by applying pressure and rotating. In addition, the diameter of the fixing button 5 is larger than that of the fixing hole 9, which serves to support and fix the spiral needle 8 and the absorbent cotton 4.
[0023] Working principle: like Figure 1 - Figure 5 As shown, after the circuit board surface is cleaned in the ultrasonic cleaning machine, the surface of the absorbent cotton 4 clamped in the support plate 2 is pressed down by manually pressing the pressure plate 3 to bring it close to the support plate 2, thus clamping the upper and lower surfaces of the circuit board. At this time, the upper and lower absorbent cotton 4 come into contact with the circuit board surface and begin to absorb the residual moisture. As the moisture in the absorbent cotton 4 gradually increases, the excess water will flow into the collection box 7 along the collection port 16. The spring 13 is compressed during the pressing process. After the pressure on the pressure plate 3 is released, the spring 13 automatically rebounds, allowing the pressure plate 3 to return to its initial position.
[0024] If the absorbent cotton 4 needs to be replaced or cleaned, the fixing button 5 can be rotated to pull the fixing spiral pin 8 out of the absorbent cotton 4, and then the absorbent cotton 4 can be removed for replacement or cleaning. When the water stains in the collection box 7 accumulate to a certain extent, push the push rod 10 to disengage the locking spring 14 from the sliding groove, and the collection box 7 can be disassembled. After emptying the water stains, reinstall the collection box 7 into the fixing frame 11, ensuring that the locking spring 14 is embedded in the sliding groove to complete the fixing.
[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
