Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for conformal coating machines, and more specifically, to an ultrasonic cleaning device for conformal coating machines. Background Technology

[0002] A coating machine, also known as an adhesive applicator, glue sprayer, or oil sprayer, is an automated mechanical device that controls and coats fluids onto the surface of a product. The coating machine applies a new material to the product surface, providing excellent waterproofing, dustproofing, and anti-static properties. With the increasing demands for circuit board stability in the electronics industry, conformal coating machines have become an indispensable part of electronic product manufacturing. By coating circuit boards with a conformal coating machine, moisture-proofing, dustproofing, and corrosion-proofing effects can be achieved.

[0003] Because existing conformal coatings typically have high viscosity, they tend to adhere to the inner wall of the valve nozzle when flowing through it. Over time, this can lead to the formation of a hardened layer inside the nozzle, reducing the flow area and causing blockages. Therefore, the nozzle needs to be cleaned. Currently, cleaning the nozzle involves installing a bubble cup tank on a conformal coating machine and then controlling the machine to move the nozzle into the tank for ultrasonic cleaning. To prevent water from splashing inside the bubble cup tank during ultrasonic cleaning, the opening in the tank is usually set to be the same diameter as the nozzle.

[0004] However, in actual use, because the opening on the cup tank has the same diameter as the valve nozzle, the valve nozzle is prone to contact with the edge of the opening on the cup tank during downward movement, causing a collision. After frequent collisions, the valve nozzle is prone to loosening at the connection with the machine, thus affecting the coating effect. Utility Model Content

[0005] The present invention provides an ultrasonic cleaning device for a three-proof coating machine. The problem to be solved is that, because the opening on the existing cup tank has the same diameter as the valve nozzle, the valve nozzle is easy to come into contact with the edge of the opening on the cup tank during the downward movement, causing collisions. After frequent collisions, the valve nozzle is prone to loosening at the connection with the machine, thus affecting the coating effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic cleaning device for a three-proof coating machine, comprising a first bubble cup tank and a second bubble cup tank, a cover plate detachably installed on the top of the first bubble cup tank, a collection port provided at the bottom of the second bubble cup tank, limit plates fixedly installed on both sides of the top of the first bubble cup tank and the second bubble cup tank, the cover plate being located on the top of the limit plates, and a mounting bracket detachably connected to the bottom of the limit plates, the mounting bracket being used for installing the first bubble cup tank and the second bubble cup tank, an ultrasonic cleaning vibrating head being installed at the bottom of the first bubble cup tank, and wiring terminals being provided on the surface of the ultrasonic cleaning vibrating head;

[0007] The cover plate has a socket, and an anti-collision component is provided inside the socket. The anti-collision component includes two inclined guide plates, which are slidably installed inside the socket. The inclined guide plates are used to control the opening and closing of the socket when they slide left and right.

[0008] In a preferred embodiment, a rubber layer is provided on each side of the inclined guide plate, and a slider is fixedly installed on each of the two inclined guide plates on opposite sides, with the slider slidingly inserted into the side wall of the insertion hole.

[0009] In a preferred embodiment, a sponge block is provided at a lower position on opposite sides of the inclined guide plate, with both ends of the sponge block hinged to the inclined guide plate and the two sponge blocks in contact.

[0010] In a preferred embodiment, the outer end of the slider is connected to a plurality of springs, and the other end of the springs is connected to the inner wall of the socket.

[0011] In a preferred embodiment, both the first and second brewing cups are detachably equipped with filter boxes. A U-shaped scraper is slidably engaged with the outside of the filter box, with one side of the U-shaped scraper in contact with the filter box and a connecting rod installed at the top of the U-shaped scraper.

[0012] In a preferred embodiment, a first scraper is fixedly provided on both sides of the bottom of the filter box. The first scraper is located on both sides of the U-shaped scraper. Both the first scraper and the U-shaped scraper are used to scrape the inner wall of the first or second brewing cup.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting an inclined guide plate, when the valve nozzle is inserted into the first bubble cup groove through the insertion hole, the inclined guide plate slides left and right to control the opening and closing of the insertion hole when it contacts the valve nozzle, so that the size of the insertion hole matches the range of the valve nozzle to be inserted into the insertion hole, ensuring that the valve nozzle can be smoothly inserted into the insertion hole without obstruction. At the same time, the contact of the sponge block closes the gap between the insertion hole and the valve nozzle, preventing the cleaning liquid from splashing when cleaning the valve nozzle.

[0015] 2. By setting up a filter box, the conformal coating inside the valve nozzle falls off into the inner cavity of the filter box while the valve nozzle is being cleaned. This allows for the centralized collection of conformal coating clumps inside the valve nozzle. When the U-shaped scraper is pushed, it can clean the inner wall of the first or second brewing cup. When the filter box is lifted, the first scraper scrapes and cleans the inner wall of the first or second brewing cup as the filter box moves upward. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual appendix Figures 1 to 6An ultrasonic cleaning device for a three-proof coating machine includes a first bubble cup tank 2 and a second bubble cup tank 3. A cover plate 8 is detachably installed on the top of the first bubble cup tank 2. A collection port 7 is provided at the bottom of the second bubble cup tank 3. Limiting plates 6 are fixedly installed on both sides of the top of the first bubble cup tank 2 and the second bubble cup tank 3. The cover plate 8 is located on the top of the limiting plate 6. A mounting bracket 1 is detachably connected to the bottom of the limiting plate 6. The mounting bracket 1 is used to install the first bubble cup tank 2 and the second bubble cup tank 3. An ultrasonic cleaning vibrating head 4 is installed at the bottom of the first bubble cup tank 2. A wiring terminal 5 is provided on the surface of the ultrasonic cleaning vibrating head 4.

[0025] The cover plate 8 has a socket on its surface. An anti-collision component is provided inside the socket. The anti-collision component includes two inclined guide plates 10. The two inclined guide plates 10 are slidably installed inside the socket. When the inclined guide plates 10 slide left and right, they are used to control the opening and closing of the socket.

[0026] It should be noted that the mounting bracket 1 installs the first bubble cup 2 and the second bubble cup 3 on the conformal coating equipment. The first bubble cup 2 and the second bubble cup 3 are pre-filled with cleaning fluid. The coating equipment controls the valve insertion hole. During the valve insertion process, the inclined guide plate 10 contacts the valve nozzle and slides left and right to control the opening and closing of the hole, so that the size of the hole matches the valve nozzle and the range of the valve nozzle to be inserted into the hole. This ensures that the valve nozzle can be smoothly inserted into the hole without obstruction. When the valve nozzle enters the inner cavity of the first bubble cup 2, during the bubble process, the ultrasonic cleaning vibrating head 4 uses high-frequency vibration to clean the cleaning fluid in the first bubble cup 2, cleaning the valve nozzle and removing residual paint. At the same time, the two sponge blocks 12 are pushed and contacted by the spring 14 to close the gap between the hole and the valve nozzle, which can prevent the cleaning fluid from splashing during the cleaning of the valve nozzle due to vibration.

[0027] Furthermore, each of the inclined guide plates 10 has a rubber layer 11 on its opposite side, and each of the two inclined guide plates 10 has a slider 13 fixedly installed on its opposite side, with the slider 13 slidably inserted into the side wall of the insertion hole.

[0028] In the above embodiment, the slider 13 drives the inclined guide plate 10 to slide inside the socket, thereby moving the inclined guide plate 10 left and right, opening and closing the inclined guide plate 10, and preventing the valve from bumping when it moves down through the rubber layer 11.

[0029] Furthermore, a sponge block 12 is provided on the lower side of the inclined guide plate 10, with both ends of the sponge block 12 hinged to the inclined guide plate 10 and the two sponge blocks 12 in contact with each other.

[0030] In the above embodiment, when the two sponge blocks 12 come into contact, the gap between the insertion hole and the valve nozzle can be sealed.

[0031] Furthermore, multiple springs 14 are connected to the outer end of the slider 13, and the other end of the spring 14 is connected to the inner wall of the socket.

[0032] In the above embodiment, the inclined guide plate 10 is made elastic by the spring 14, and the inclined guide plate 10 automatically resets when it is no longer subjected to the thrust of valve insertion.

[0033] Furthermore, the first brewing cup trough 2 and the second brewing cup trough 3 are each detachably equipped with a filter box 15. A U-shaped scraper 17 is slidably engaged on the outside of the filter box 15. One side of the U-shaped scraper 17 contacts the filter box 15, and a connecting rod 18 is installed at the top of the U-shaped scraper 17.

[0034] In the above embodiment, the filter box 15 can collect residual paint in a concentrated manner, and when the U-shaped scraper 17 is pushed, the U-shaped scraper 17 can clean the inner wall of the first brewing cup 2 or the second brewing cup 3 during the movement.

[0035] Furthermore, a first scraper 16 is fixedly provided on both sides of the bottom of the filter box 15. The first scraper 16 is located on both sides of the U-shaped scraper 17. Both the first scraper 16 and the U-shaped scraper 17 are used to scrape the inner wall of the first brewing cup 2 or the second brewing cup 3.

[0036] In the above embodiment, when the filter box 15 is lifted, the first scraper 16 scrapes and cleans the inner wall of the first brewing cup 2 or the second brewing cup 3 during the upward movement of the filter box 15.

[0037] Working principle: When using this device, the mounting bracket 1 installs the first bubble cup 2 and the second bubble cup 3 on the conformal coating equipment. First, cleaning fluid is pre-filled into the first bubble cup 2 and the second bubble cup 3. Then, the coating equipment controls the valve insertion hole. During the process of the valve being inserted into the inner cavity of the first bubble cup 2 through the hole, the inclined guide plate 10 slides left and right when it contacts the valve nozzle to control the opening and closing of the hole, so that the size of the hole matches the size of the valve nozzle and the range of the valve nozzle to be inserted into the hole, ensuring that the valve nozzle can be smoothly inserted into the hole without obstruction. After the valve nozzle enters the inner cavity of the first bubble cup 2, during the bubble cup process, the ultrasonic cleaning vibrating head 4 uses high-frequency vibration to clean the cleaning fluid in the first bubble cup 2, cleaning the valve nozzle and removing residual paint. At the same time, the two sponge blocks 12 come into contact due to the spring 14 pushing the inclined guide plate 10, so that the gap between the hole and the valve nozzle is closed, which can prevent the cleaning fluid from splashing through the hole when cleaning the valve nozzle during vibration.

[0038] During the cleaning process, residual paint can be collected centrally through the filter box 15. When the U-shaped scraper 17 is pushed, the U-shaped scraper 17 can clean the inner wall of the first brewing cup 2 or the second brewing cup 3 during the movement. When the filter box 15 is lifted, the first scraper 16 scrapes and cleans the inner wall of the first brewing cup 2 or the second brewing cup 3 during the upward movement of the filter box 15.

[0039] After cleaning is completed, the valve is inserted into the inner cavity of the second bubble cup 3 by controlling the coating equipment, so that the fine particles adhering to the valve can be cleaned.

[0040] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
