Description

Technical Field

[0001] This utility model belongs to the technical field of ultrasonic spraying equipment, specifically relating to a sealed online ultrasonic spraying device. Background Technology

[0002] Ultrasonic spraying equipment is an industrial device that uses ultrasonic atomization technology for precision spraying. It utilizes the vibration energy of high-frequency ultrasound (typically 20kHz-200kHz), converting electrical energy into mechanical vibration through a piezoelectric transducer. This causes the liquid to form tiny droplets on the nozzle surface, achieving atomized spraying. Ultrasonic spraying offers advantages such as high coating uniformity, high raw material utilization, high precision in coating thickness control, thinner coatings, less splatter, no nozzle clogging, and low maintenance costs. It is widely used in fields such as new energy batteries, medical devices, aerospace technology, and microelectronics.

[0003] Currently, most existing ultrasonic spraying equipment has an independent sealed structure, which can automate the spraying process for small parts when combined with a robotic arm. However, for large parts (such as perovskite solar panels), existing ultrasonic sealed spraying equipment requires opening the sealed door and replacing the workpiece after spraying, followed by secondary gas replacement. Because the volume of the spraying equipment cannot be compressed, this results in a long replacement time, significantly reducing spraying efficiency. Furthermore, frequent opening of the sealed door allows air to enter, leading to a high oxygen content, making it impossible to achieve spraying in a low-oxygen environment and easily causing oxidation of the atomized liquid. Therefore, the structure of existing ultrasonic spraying equipment needs further improvement. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a sealed online ultrasonic spraying device. The spraying device adopts an overall sealed structure and is equipped with a feeding connection chamber and a discharging connection chamber at both the front and rear ends, realizing online continuous low-oxygen environment spraying. It has the characteristics of compact structure, high continuous spraying efficiency, saving spraying liquid consumption, and good spraying effect in low-oxygen environment. It can be widely used in the field of ultrasonic spraying technology for large-size sprayed parts.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sealed online ultrasonic spraying device, including an outer frame housing, an ultrasonic spraying component is provided inside the outer frame housing, the upper end of the ultrasonic spraying component is connected to a three-axis walking mechanism, and the lower end is connected to a feeding system; the front end of the outer frame housing is connected to a feeding dock, and the rear end is connected to a discharging dock, and a main electrical control cabinet is provided on the side of the discharging dock; a linkage roller module is also provided inside the outer frame housing, and the linkage roller module is horizontally connected to the front and rear roller modules inside the feeding dock and the discharging dock.

[0006] As an improvement of this utility model, the outer frame shell is a fully sealed metal frame structure, forming a sealed spraying chamber in the middle, and an exhaust vent is provided at the top.

[0007] As an improvement of this utility model, the ultrasonic spraying assembly is assembled by fixed connection of an ultrasonic transducer, a housing, a liquid inlet, a liquid outlet, and a cable interface.

[0009] As an improvement of this utility model, the power component of the feeding system is either a cross-flow injection pump or a pressure supply tank.

[0010] As an improvement of this utility model, both the feeding dock and the discharging dock are connected to a control cabinet to control the conveying speed of the front and rear roller modules.

[0011] As an improvement of this utility model, the feeding dock and the discharging dock are provided with flat square protective covers, making the whole structure a sealed structure, and the two ends are open to facilitate the transportation of large-sized sprayed parts.

[0012] As an improvement of this utility model, a reaction vessel is provided next to the feed connection bin.

[0013] As an improvement of this utility model, the main electrical control cabinet is an independent box with an alarm light on the top, an internal PLC control system, and a touch screen on the surface, which contains operation control software.

[0014] As an improvement of this utility model, a function button is provided below the touch screen, including a power on / off button and an emergency stop button.

[0015] The beneficial effects of this utility model are as follows: A sealed online ultrasonic spraying equipment features a compact structure, high continuous spraying efficiency, low spraying liquid consumption, and good spraying effect in a low-oxygen environment.

Detailed Implementation

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Figure 1As shown, a sealed online ultrasonic spraying device includes an outer frame housing 1. An ultrasonic spraying assembly 2 is installed inside the outer frame housing 1.

The front end of the outer frame housing 1 is connected to a feeding dock 5, and the rear end is connected to a discharging dock 6. A main electrical control cabinet 7 is installed on the side of the discharging dock 6. A linkage roller module 8 is also installed inside the outer frame housing 1. The linkage roller module 8 is horizontally connected to the front and rear roller modules inside the feeding dock 5 and the discharging dock 6, thereby realizing the assembly line transportation of the sprayed parts. When passing through the ultrasonic spraying assembly 2, rapid and efficient spraying can be completed.

[0021] Furthermore, the outer frame housing 1 is a fully sealed metal frame structure, forming a sealed spraying chamber in the middle, and has an exhaust vent 9 at the top; specifically, the outer frame housing 1 is a fixed structure with fixed support legs at the bottom, and the walking mechanism 3 moves in the hollow part in the middle.

[0022] Furthermore, such as Figure 2 As shown, the ultrasonic spraying assembly 2 is assembled by fixed connection of an ultrasonic transducer 21, a housing 22, a liquid inlet 23, a liquid outlet 24, and a cable interface 25; wherein the ultrasonic transducer 21 realizes high-frequency mechanical vibration, and then the high-frequency vibration disperses the solution into small droplets and sprays them evenly onto the surface of the workpiece.

[0023] Furthermore, such as Figure 3 The three-axis traveling mechanism 3 includes an X-axis module and servo motor 31, a Y-axis module and servo motor 32, a Z-axis module and servo motor 33, and a feeding conveyor belt and servo system 34. The three-axis traveling mechanism 3 enables the ultrasonic spraying assembly to uniformly and efficiently spray parts of different sizes and thicknesses. Specifically, the three-axis traveling mechanism 3 includes a lead screw module, servo motors, photoelectric switches, and auxiliary structures. The three-axis traveling mechanism 3 is a traveling mechanism responsible for the trajectory movement of the spray nozzle during spraying. Specifically, it may include a gantry three-axis mechanism with XYZ axes. The feeding conveyor belt and servo system 34 includes a linkage roller module, a reduction motor, photoelectric switches, and position limiting cylinders, etc. This mechanism is a transport mechanism for the sprayed parts (such as solar panels). It is responsible for transporting the sprayed parts to the spraying position during spraying and to the next process after spraying, achieving automated transport and improving spraying production efficiency.

[0024] Furthermore, the power source of the feeding system 4 is either a cross-flow injection pump or a pressure supply tank, preferably a cross-flow injection pump. Specifically, the feeding system 4 includes a precision injection pump, a proportional valve (installed inside the equipment), a switching valve (installed inside the electrical control cabinet), fixed sheet metal, and auxiliary pipelines. The automatic feeding system 4 is fixed inside the lower part of the outer frame housing 1 and cooperates with the ultrasonic spraying assembly 2 through a PLC control system to stably supply material to the entire system and meet the customer's quota spraying requirements.

[0025] Furthermore, both the feeding dock 5 and the discharging dock 6 are connected to a control cabinet 10, which controls the conveying speed of the front and rear roller modules to meet the conveying speed requirements of different sized sprayed parts. Furthermore, the feeding dock 5 and the discharging dock 6 are equipped with flat square protective covers, making them a sealed structure with open ends to facilitate the conveying of large-sized sprayed parts and improve conveying efficiency.

[0026] Furthermore, a reaction vessel 11 is provided on the side of the feeding dock 5, through which the atomizing liquid required for spraying is provided to the feeding system 4.

[0027] Furthermore, the main electrical control cabinet 7 is an independent enclosure with an alarm light 12 on the top, an internal PLC control system, and a touch screen 13 on its surface.

The software also has access permissions; different accounts have different functions to meet diverse customer needs. Additionally, any equipment malfunctions are displayed in the software and recorded. When an malfunction occurs, the alarm light 12 will activate a three-color alarm. Furthermore, below the touch screen 13 are function buttons 14, including a power on / off switch and an emergency stop button.

[0028] This utility model discloses a sealed online ultrasonic spraying device, which features a compact structure, high continuous spraying efficiency, low spraying liquid consumption, and good spraying effect in a low-oxygen environment. It employs ultrasonic precision spraying, combined with automated operation using rollers to spray parts (such as solar panels). The parts are conveyed through the roller module inside the feeding hopper 5 to the area below the ultrasonic spraying assembly 2 inside the outer frame housing 1. Once the position is detected, the system stops the conveying, and the three-axis walking mechanism 3 drives the ultrasonic spraying assembly 2 for automatic spraying. After spraying is complete... After completion, the sprayed parts are transported by the linkage roller module 8 to the roller module inside the discharge receiving chamber 6, and finally transported to the end outlet. Structurally, due to the design of the front and rear receiving chambers and the sealed design with the spraying chamber, the spraying is carried out in a stable low-oxygen environment, which effectively reduces the oxidation of the spraying atomized liquid after contact with oxygen. It replaces conventional scraping or spin coating, resulting in better effect, lower energy consumption, and higher production efficiency. The use of self-developed control software can control and set the parameters of each component, so that the various processes are closely integrated, further improving production efficiency.
