Description

TECHNICAL FIELD

[0001] The utility model relates to solder resist ink processing technical field, specifically point to a kind of convenient cleaning's solder resist ink dispersion device. BACKGROUND

[0002] Solder resist ink dispersion device is used to uniformly disperse solid pigment particles in solder resist ink in liquid medium, and plays a key role in PCB manufacturing, such as protecting circuit, preventing short circuit and chemical corrosion. It realizes dispersion by means of high-speed stirring, grinding and ultrasonic, etc. High-speed stirring relies on blade shear force to break and disperse pigment, and grinding machine uses grinding beads to refine particles.

[0003] In the current printed circuit board (PCB) manufacturing process, the dispersion of solder resist ink is crucial. Although the existing solder resist ink dispersion device can preliminarily uniformly mix solid pigment and liquid medium, its dispersion effect has obvious shortcomings. The treated solid pigment particles are still large, which makes it difficult to fully play the role of protecting the circuit and preventing short circuit in the subsequent soldering process, seriously affecting the quality and performance of the PCB. In addition, the cleaning work inside the device is extremely difficult. Since solid pigment and liquid medium have strong adhesion, a large amount of residual material adheres tightly to the inner wall and components of the device after the dispersion operation is completed. The traditional cleaning method is time-consuming and labor-intensive, and it is difficult to completely remove it, which not only increases the maintenance cost, but also may cause cross contamination of different batches of ink due to incomplete cleaning.

[0005] To solve the above technical problems, the utility model provides a technical scheme: a solder resist ink dispersion device convenient to clean, comprising:

[0006] The outer cylinder is an open-top cylinder with a bottom plate connected by a plurality of support rods.

[0007] The inner cylinder is detachably arranged in the outer cylinder and is also an open-top cylinder. A discharge pipe is arranged on the lower wall of the inner cylinder. The lower end of the discharge pipe penetrates the bottom surface of the outer cylinder, and a valve is arranged on the discharge pipe.

[0008] The dispersion mechanism includes a rotating shaft, dispersion leaves and a motor. The rotating shaft is arranged in the inner cylinder and is rotatably connected to a support plate at the upper end. The support plate is detachably arranged above the outer cylinder. The motor is fixedly arranged on the support plate to drive the rotating shaft to rotate. The dispersion leaves are arranged on the side wall of the rotating shaft.

[0009] An ultrasonic cavitation device is located directly below the discharge pipe on the base plate. A detachable top cover is provided above it, and a second discharge pipe is provided on one side below it. A second valve is provided on the second discharge pipe.

[0010] Furthermore, the inner wall of the outer cylinder is provided with several guide strips at equal intervals, the outer wall of the inner cylinder is provided with guide grooves matching the guide strips, and the upper end of the inner cylinder is provided with several handles.

[0011] Furthermore, the lower wall of the outer cylinder is provided with a slidingly extending pipe hole for the feed pipe.

[0012] Furthermore, a plurality of L-shaped rods are integrally formed on the side wall of the support plate, and the other end of the L-shaped rods and the upper wall of the outer cylinder are provided with interlocking slots.

[0013] Furthermore, a connecting plate is connected to one end of the dispersing leaf near the rotating rod, and the connecting plate is fixed to the rotating rod by screws.

[0014] Furthermore, the ultrasonic cavitation device is equipped with an ultrasonic device and a container for temporarily storing ink, and the discharge pipe is connected to the container.

[0015] Compared with existing technologies, the advantages of this invention are as follows: the combined design of the outer and inner cylinders makes cleaning the device extremely convenient. The inner cylinder is detachably installed inside the outer cylinder, and with the guide strips on the inner wall of the outer cylinder, the guide grooves on the outer wall of the inner cylinder, and the handle at the top of the inner cylinder, it is easy to remove the inner cylinder for separate cleaning. Moreover, components such as the discharge pipe on the lower wall of the inner cylinder, the rotating rod in the dispersion mechanism, and the dispersion blades can also be separated when cleaning is required, avoiding ink residue. In addition, the support plate is connected to the outer cylinder through an L-shaped rod and a slot, further enhancing the disassembly capability of the structure, making the cleaning work more thorough, and extending the service life of the device.

[0016] The ultrasonic cavitation unit is located directly below the discharge pipe. Its internal ultrasonic equipment generates a cavitation effect, refining solid pigment particles to a smaller size, resulting in a more uniform distribution of solid pigment in the ink. These finer particles improve the coverage of the solder resist ink, enhancing its solder resist performance and ensuring more even coverage on surfaces such as circuit boards during use. This forms a higher-quality solder resist layer, effectively preventing solder from flowing into unwanted areas and improving the quality and reliability of the circuit board.
