Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ink cleaning equipment, and in particular to a solder resist ink cleaning line. Background Technology
[0002] In the manufacturing process of PCBs, the solder mask process is a fundamental step. This process mainly involves screen printing a layer of ink onto the copper surface of the PCB to prevent copper oxidation and avoid exposing copper surfaces that do not require soldering, thereby preventing short circuits. However, during the application of solder mask ink, a certain percentage of defective products will be generated due to uneven ink distribution, incorrect application location, or improper ink color. To save costs, these defective products need to be recycled and reworked.
[0003] Currently, traditional green oil stencil washing methods mainly rely on manual operation. Specifically, defective products are first immersed in a heated special solution tank, and then rinsed multiple times through a developing line. Some improved processes have added steps such as ultrasonic cleaning and high-pressure rinsing to improve cleaning efficiency and quality.
[0004] While these methods improve cleaning efficiency to some extent, they still have some significant drawbacks. First, manual handling not only increases labor costs, but also poses a risk of scratching or damaging the PCB board surface during handling and loading / unloading. Utility Model Content
[0005] To reduce manual intervention, improve cleaning efficiency and quality, and reduce the risk of damage to the surface of the board during washing, this application provides a solder resist ink cleaning line.
[0006] To achieve the above objectives, this application adopts the following technical solution:

The top cover is fixed to the top of the column, the transmission component is connected to the top cover, the telescopic component is fixed to the transmission component, and the clamp is fixed to the telescopic component. The clamp is used to hold the tumbler plate and move it through the transmission component, and immerses the tumbler plate into the cleaning tank through the telescopic component.
[0008] By employing the aforementioned device and transmission system, the tilting plate is moved, reducing manual intervention and preventing potential damage during manual handling, thus protecting the plate surface. Furthermore, the transmission system immerses the tilting plate in the cleaning tank, thereby improving cleaning efficiency and quality.
[0009] Preferably, the cleaning tank is provided with a heating element, an air inlet, a medicine inlet, and a medicine outlet. The air inlet extends to the bottom of the cleaning tank, the heating element is located on both sides of the cleaning tank, the medicine inlet is located at the top of the cleaning tank, and the medicine outlet is located at the bottom of the cleaning tank.
[0010] By employing the above-described device, the heating element can heat the cleaning solution, ensuring it maintains a suitable temperature and thus improving cleaning efficiency and effectiveness. Gas is blown into the air inlet pipe, thoroughly agitating the cleaning solution and ensuring a uniform distribution of its chemical components. The inclusion of a drug inlet and outlet allows for convenient replenishment and replacement of the cleaning solution, timely removal of waste liquid, and maintenance of its freshness and cleaning effectiveness.
[0011] Preferably, there are three cleaning tanks: a first cleaning tank, a second cleaning tank, and a third cleaning tank. These three cleaning tanks are positioned between the loading machine and the unloading machine, and are arranged sequentially according to the movement order of the flipping plates.

[0013] Preferably, the second cleaning tank is further provided with an ultrasonic device, which is fixed to one side of the heating tube.
[0014] By using the above-mentioned device, the ultrasonic device generates a cavitation effect through high-frequency vibration, which can penetrate into the tiny gaps of the tumbler plate, effectively removing stubborn stains and residues, and further improving the cleaning effect of the tumbler plate.
[0015] Preferably, the third cleaning tank is equipped with a rinsing device, which includes an inlet pipe and a nozzle. The inlet pipe is symmetrically arranged in the third cleaning tank, and the nozzle is connected to the inlet pipe.
[0016] Preferably, the nozzle is provided with multiple nozzles, which move up and down along the liquid inlet pipe.
[0017] By using the above-mentioned device, the moving nozzles can cover every corner of the tumbler plate, reduce cleaning dead spots, ensure the cleaning range, and further improve the overall cleaning quality of the tumbler plate.
[0018] Preferably, the second and third cleaning tanks are further equipped with a filter device for filtering oil residue.
[0019] By using the above-mentioned device, the continuous filtration of the filtration device reduces the accumulation of impurities in the cleaning solution, keeps the cleaning solution clean, thereby improving the cleaning effect, extending the service life of the cleaning solution, and reducing the cleaning cost.
[0020] Preferably, both the loading machine and the unloading machine are equipped with a loading frame for placing the tumbled boards, and both the loading machine and the unloading machine are equipped with a robotic arm above them. The tumbled boards are transferred from the loading machine to the clamp by the robotic arm, and then transferred from the clamp to the unloading machine by the robotic arm.
[0021] By adopting the above-mentioned device, the use of robotic arms has enabled the automated transfer of the washing plates from the loading machine to the clamp, and then from the clamp to the receiving machine. This reduces manual operation, improves production efficiency, reduces the risk of damage to the washing plates during the transfer process, improves the working efficiency and stability of the entire cleaning line, and enhances the overall performance of the production line.
[0022] This application has the following beneficial effects:
[0023] 1. In this application, the movement of the rinsing plate is achieved through a transmission system, reducing manual intervention and avoiding potential damage to the rinsing plate during manual handling, thus protecting the plate surface. Furthermore, the transmission system immerses the rinsing plate in the cleaning tank for cleaning, thereby improving cleaning efficiency and quality.
[0024] 2. In this application, the heating element can heat the cleaning solution, ensuring that the cleaning solution maintains a suitable temperature, thereby improving cleaning efficiency and effectiveness.

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0030] Example:
[0031] A solder resist ink cleaning line, such as Figure 1 As shown, the system includes a transmission system 1, a loading machine 2, a cleaning cylinder 3, and a collecting machine 4. The transmission system 1 is located above the cleaning cylinder 3 to facilitate the clamping and movement of the tumblers for cleaning. The loading machine 2 is located on one side of the cleaning cylinder 3 and is used to place undone tumblers, while the collecting machine 4 is located on the other side of the cleaning cylinder 3 and is used to place cleaned tumblers.
[0032] like Figure 1-2 As shown, the cleaning tank 3 is equipped with heating elements 5, an air inlet 6, a medicine inlet 7, and a medicine outlet 8. The heating elements 5 are symmetrically installed on both sides of the cleaning tank 3 and are L-shaped, which increases the contact area with the cleaning fluid, providing a more uniform heating effect and ensuring a balanced temperature of the cleaning fluid. The air inlet 6 extends to the bottom of the cleaning tank 3 to improve gas diffusion, allowing for thorough mixing of the cleaning fluid and ensuring a uniform distribution of chemical components. The medicine inlet 7 and medicine outlet 8 are located at the top and bottom of the cleaning tank 3, respectively, allowing for convenient replenishment and replacement of the cleaning fluid, timely removal of waste liquid, and ensuring the freshness of the cleaning fluid and the cleaning effect.
[0033] In addition, such as Figure 1 As shown, the cleaning tank 3 has three sections: a first cleaning tank 31, a second cleaning tank 32, and a third cleaning tank 33. Driven by the transmission system 1, the washing plate is sequentially immersed in the first cleaning tank 31, the second cleaning tank 32, and the third cleaning tank 33. After three cleaning cycles, the ink on the washing plate is effectively removed, improving the cleaning effect. Furthermore, the washing plate moves automatically under the drive of the transmission system 1, reducing manual handling and improving cleaning efficiency while also reducing the risk of scratches or damage that may occur during manual handling.
[0034] Specifically, such as Figure 1 As shown, the transmission system 1 includes a column 11, a top cover 12, a transmission component 13, clamps 14, and a telescopic component 15. The column 11 uses a rectangular tube structure to ensure structural strength. The top cover 12 is fixed to the top of the column 11, and the transmission component 13 is mounted below the top cover 12 via a support column, positioning the transmission component 13 directly above the three cleaning cylinders 3. The transmission component 13 includes a motor and a transmission chain, and the motor and transmission chain are connected via a sprocket drive to ensure transmission stability. The telescopic component 15 is mounted on the transmission component 13 and moves cyclically under the drive of the transmission component 13. In this embodiment, the telescopic component 15 is a cylinder, with a mounting strip fixed to the output end of the cylinder. Two clamps 14 are fixed to the mounting strip for holding the tumbling plate.
[0035] During operation, driven by the transmission component 13, the clamp 14 holds the rinsing plate and moves it between multiple cleaning cylinders 3, while the telescopic component 15 allows the rinsing plate to be immersed in different cleaning cylinders 3 in sequence for cleaning, reducing manual handling and improving cleaning efficiency.
[0036] like Figure 1 As shown, in order to further improve the cleaning effect of ink on the washing plate, an ultrasonic device 321 is installed in the second washing tank 32. The ultrasonic device 321 is symmetrically installed on both sides of the second washing tank 32. Through high-frequency vibration, it generates a cavitation effect, which can penetrate into the tiny gaps of the washing plate to achieve a better cleaning effect.
[0037] In addition, such as Figure 1 As shown, a rinsing device 331 is installed inside the third cleaning tank 33. The rinsing device 331 includes an inlet pipe 331a and nozzles 331b. The inlet pipe 331a is made of corrosion-resistant PP material and is symmetrically arranged inside the third cleaning tank 33. The nozzles 331b are connected to the inlet pipe 331a. There are multiple nozzles 331b, and in this embodiment, the nozzles 331b are high-pressure nozzles. During operation, the nozzles 331b can move up and down along the inlet pipe 331a to ensure thorough cleaning of the surface of the washing plate.
[0038] like Figure 1-2 As shown, the second cleaning tank 32 and the third cleaning tank 33 are also equipped with a filter device 9. The filter device 9 filters the oil residue in the cleaning fluid to reduce the accumulation of impurities in the cleaning fluid, keep the cleaning fluid clean, and extend the service life of the cleaning fluid, thereby further improving the cleaning effect of the washing plate.
[0039] like Figure 2 As shown, the loading machine 2 is equipped with a loading frame 21 for placing unwashed tumbled boards, and the receiving machine 4 is also equipped with a loading frame 21 for placing washed tumbled boards. Furthermore, a robotic arm 22 is installed above the loading machine 2 to transfer the tumbled boards from the loading machine 2 to the clamp 14. Similarly, a robotic arm 22 is installed above the receiving machine 4 to transfer the tumbled boards from the clamp 14 to the receiving machine 4, thus achieving an automated loading and unloading process for the tumbled boards. This reduces manual operation, minimizes the risk of damage to the tumbled boards during transfer, and improves the overall efficiency and stability of the cleaning line.
[0040] Working principle: During operation, the robotic arm 22 transfers the tumblers placed in the upper plate machine 2 to the clamp 14. Then, through the cooperation of the transmission component 13 and the telescopic component 15, the tumblers are sequentially immersed in three cleaning tanks 3: soaking in the first cleaning tank 31, ultrasonic cleaning in the second cleaning tank 32, and high-pressure rinsing in the third cleaning tank 33. After cleaning, the robotic arm 22 transfers the tumblers on the clamp 14 to the plate collecting machine 4, effectively improving the cleaning efficiency of the tumblers and reducing the risk of damage to the tumblers caused by manual handling.
[0041] 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.
