Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment, specifically a novel ultrasonic ink removal and cleaning machine. Background Technology

[0002] In high-end manufacturing fields such as electronic information, photovoltaic new energy, and precision optical components, the surface cleanliness of glass substrates directly affects the functional reliability and yield rate of products. Among these, removing ink residues from positioning marks, defective product labels, or previous processes is a key cleaning step. Existing ultrasonic glass ink removal cleaning machines still have some shortcomings in practical applications: Currently, most ultrasonic glass cleaning machines use a manual loading and unloading operation mode. During the production process, operators need to manually transfer the glass to be cleaned from the turnover tray or loading rack to the special clamps in the cleaning machine chamber. After cleaning, the glass needs to be removed one by one and transferred to the next process. This is labor-intensive and inefficient, and the manual transfer method is also prone to causing secondary pollution on the glass. Glass surface inks, especially UV-cured inks and epoxy resin inks, typically possess high adhesion and strong chemical stability. Their removal relies on the synergistic effects of micro-jets generated by ultrasonic cavitation, swelling of the cleaning solution, and chemical reactions. However, for thick-film inks (thickness > 5 μm) or multi-layered inks, a single cleaning cycle cannot completely remove them through cavitation, easily leaving microscopic residues on the glass surface. Furthermore, different glass materials and ink types exhibit significant differences in their sensitivity to ultrasonic frequency, power density, and cleaning solution temperature. Existing equipment often employs fixed parameter modes, making dynamic adjustments for different workpieces difficult, further reducing cleaning efficiency.

[0003] Existing cleaning machine fixtures are mostly made of metal, using bolts or slots to fix the glass. These fixtures are prone to leaving ink particles that were not completely removed in previous cleaning processes. These residual ink particles can fall off under the influence of gravity, ultrasonic vibration, or the flow of cleaning fluid, and then re-adhere to the surface of newly placed glass, causing secondary or cross-contamination.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a novel ultrasonic ink removal cleaning machine, including a lifting structure 1, a cleaning structure 2 and a conveyor belt 3. The lifting structure 1 is used to lift a basket 4. The cleaning structure 2 includes several cleaning boxes 21 arranged side by side. The basket 4 carries the glass to be cleaned and sinks into the cleaning box 21 for cleaning. The cleaning box 21 is connected to an external ultrasonic generator and is mounted on the bracket 5. The support frame 5 is equipped with a protective cover 6, which is made of transparent acrylic panels and features a sealed design to prevent cleaning fluid from splashing. This isolates the cleaning area from the outside environment, reducing noise, dust, and the evaporation of cleaning fluid. The protective cover 6 is equipped with a vibration structure 7 that corresponds one-to-one with the cleaning box 21. The vibration structure 7 includes a contact piece 71, and the contact piece 71 is provided with a vibrating plate. When the contact piece 71 contacts the cleaning box 21, it can remove the residual cleaning liquid on the basket 4 through vibration. The conveyor belt 3 is located at the end of the support 5.

[0022] In this embodiment, the lifting structure 1 includes a guide rail 11, a hoist 12, and a hook 13. The guide rail 11 is installed on the production line, the hoist 12 is installed on the guide rail 11 and can move on the guide rail 11, and the hook 13 is connected to the hoist 12 by a sling. Guide rail 11 is a linear slide rail, with a length covering the production line cleaning area to the conveyor belt, and its surface is chrome-plated for wear resistance; The 12-type hoist is an electric hoist with a lifting capacity of 50-200kg, equipped with a variable frequency motor for speed control; The hook 13 is made of alloy steel and has an anti-disengagement buckle. It is connected to the hoist 12 via a wire rope.

[0023] The hoist 12 is moved by the guide rail 11 to accurately lift the basket 4 from the loading area to the cleaning structure 2. After cleaning, it is transferred to the conveyor belt 3 to avoid secondary pollution from manual contact with the glass products. The guide rail 11 passes through the protective cover 6 and extends to the middle of the conveyor belt 3, enabling seamless connection from cleaning to unloading and reducing transfer time.

[0024] In this embodiment, the guide rail 11 passes through the interior of the protective cover 6 and extends at least rearward to the middle position of the conveyor belt 3.

[0025] In this embodiment, the cleaning tank 21 contains cleaning fluid, and the internal space of the cleaning tank 21 is large enough to place the basket 4 entirely into the cleaning fluid, and adjacent cleaning tanks 21 do not come into contact with each other.

[0026] The cleaning tank 21 is made of 304 stainless steel with a thickness of 3mm, and has evenly distributed baffles inside. The ultrasonic generator has an adjustable frequency of 80-200MHz and a power density of 0.5-2W / cm³. 2 ; Support 5 is an aluminum alloy frame with a height of 1.5-2m and a load-bearing capacity of ≥500kg.

[0027] The side-by-side cleaning tanks 21 can be filled with different cleaning solutions, such as pre-wash solution, main wash solution, and rinsing solution. The baskets 4 are moved along the guide rails 11 and immersed in them in sequence to achieve the purpose of step-by-step cleaning.

[0028] Adjacent cleaning tanks 21 do not come into contact with each other to avoid vibration transmission that could cause disturbance to the cleaning fluid.

[0029] In this embodiment, the contact piece 71 is fixedly mounted on the output shaft of the cylinder 73.

[0030] In this embodiment, the cylinder 73 is fixedly installed inside the crossbeam 74, and the crossbeam 74 is fixedly installed on the outside of the protective cover 6.

[0031] The vibrating plate is a piezoelectric ceramic plate with a frequency of 50Hz and an amplitude of 0.5-1mm; After cleaning, cylinder 73 drives contact plate 71 to press against the outer wall of cleaning tank 21, and the high-frequency vibration of the vibrating plate is transmitted to basket 4, which removes residual cleaning liquid from the surface through mechanical impact. The contact piece 71 is made of rubber to buffer vibration and prevent damage to the cleaning box 21.

[0032] In this embodiment, the basket 4 is provided with a drain hole.

[0033] Basket 4 is a metal mesh basket with drainage holes that allow cleaning fluid to flow out quickly, preventing excessive liquid residue on the basket itself and reducing secondary sources of contamination.

[0034] In this embodiment, the ultrasonic frequency inside the cleaning tank 21 is 80MHz-200MHz.

[0035] High-frequency ultrasonic waves at 80-200MHz excite the cleaning fluid to create a cavitation effect, resulting in a micro-jet impact force ≥1000N / m. 2 Through swelling and chemical reaction, the peeling rate of UV / epoxy resin ink on the glass surface is ≥99.5%. Working principle: The glass to be cleaned is manually loaded into basket 4 and placed in the loading area; The hoist 12 moves along the guide rail 11 to above the basket, the hook 13 descends to hook the basket, lifts it and moves it along the guide rail to directly above the cleaning structure 2; The basket 4 is lowered and immersed in the first cleaning tank 21.

[0036] The cleaning chamber 21 is connected to the ultrasonic generator, and the 80-200MHz ultrasonic wave is activated. The cavitation effect, combined with the swelling and peeling of the ink by the cleaning fluid, causes the basket 4 to vibrate in the cleaning fluid. After pre-washing, hoist 12 lifts the basket and transfers it to the secondary cleaning box 21 for repeated washing; Finally, it was transferred to the third cleaning tank 21.

[0037] While the cleaning is in progress, the basket 4 is raised into the protective cover 6, and the cylinder 73 drives the contact piece 71 to contact the outer wall of the cleaning tank 21. The high-frequency vibration of the vibrating plate is transmitted to basket 4, peeling off the residual cleaning liquid from the surface and dripping it back into the cleaning tank. The hoist 12 transfers the basket 4 to the conveyor belt 3, which automatically transports it to the drying process.

[0038] Based on the above, this equipment achieves the following through automated loading and unloading, multi-stage ultrasonic cleaning, and subsequent mechanical vibration pulse dehydration: The high-frequency cavitation effect of ultrasonic cleaning works synergistically with the cleaning fluid to achieve ink cleaning; The contact plate transmits vibrations to help remove residual cleaning fluid from the basket and glass surface; The lifting structure is connected to the conveyor belt to avoid manual contact. The perforated basket reduces its own residue and minimizes cross-contamination.

[0039] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
