Description

Technical Field

[0001] This utility model relates to the field of PCB production equipment technology, and in particular to a circuit board printing ink production sorting device. Background Technology

[0002] In the field of PCB printing ink production, existing technologies typically employ manual or semi-automated equipment for ink formulation, testing, and sorting. Ink is injected into the production system through a simple feeding device, followed by testing of specific ink properties using a single testing device (such as a viscometer or particle size analyzer). After testing, the ink is usually sorted and stored manually or through simple diversion devices; some equipment is equipped with basic piping systems and storage containers. This production method is widely used in small- to medium-scale production and can meet basic ink quality requirements. However, the testing and sorting processes often rely on manual intervention, resulting in low automation and difficulty in achieving real-time monitoring of multiple parameters and accurate sorting. Especially with the increasing demand for high-precision PCB printing, existing technologies appear inefficient and ill-suited to diverse production needs.

[0003] The shortcomings of existing technologies are mainly reflected in the following aspects: First, the testing equipment is limited, only capable of detecting some performance parameters of ink, such as viscosity or particle size, lacking comprehensive testing capabilities for color, optical properties, etc., resulting in incomplete quality control. Second, the sorting process relies heavily on manual operation or simple mechanical diversion, lacking intelligent control, which easily leads to ink mixing or sorting errors. Furthermore, the feeding system of existing devices lacks effective flow control and impurity filtration functions, affecting the stability of ink quality. In terms of maintenance, the cleaning and drainage design of the liquid storage tank is inadequate, increasing operational complexity. These shortcomings limit the improvement of production efficiency and ink quality, failing to meet the demands of the modern circuit board printing industry for high-precision, high-efficiency automated production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circuit board printing ink production sorting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circuit board printing ink production and sorting device includes a feeding mechanism for injecting ink into the device, located at the top of the device, and including a feeding hopper with a flow control valve at the lower end of the feeding hopper; and a detection mechanism for detecting the ink, located below the feeding mechanism and connected to the feeding mechanism, including a detection box with a feeding port at the top that matches the discharge port of the flow control valve.

[0007] Preferably, the testing mechanism also includes a particle size analyzer, a viscometer, and an optical sensor, with the detection ends of the particle size analyzer, viscometer, and optical sensor all located inside the testing chamber.

[0008] Preferably, it further includes: a sorting mechanism for sorting and storing inks with the same composition, located below the testing mechanism, including a short tube, the short tube connecting to the interior of the testing box, a main pipe fixed at the lower end of the short tube, and several branch pipes connected to the main pipe.

[0009] Preferably, the sorting mechanism also includes electromagnetic diverter valves and a liquid storage tank. Electromagnetic diverter valves are installed on several branch pipes, and the ends of the branch pipes are connected to the liquid storage tanks via flexible hoses.

[0010] Preferably, it also includes a PLC controller for receiving the detection data from the testing organization and controlling the operation of the electromagnetic diverter valve based on the detection data.

[0011] Preferably, it further includes: a base plate located at the bottom layer of the device; a bracket fixedly mounted on the base plate for fixing the feeding mechanism, the detection mechanism, and the PLC controller; the feeding mechanism also includes a filter screen, which is installed at the liquid outlet of the feeding hopper for filtering ink; the sorting mechanism also includes a drain pipe, which is connected to and installed below the side wall of the liquid storage tank, and a valve is provided on the drain pipe.

[0012] This utility model has the following beneficial effects:

[0013] 1. This invention integrates a particle size analyzer, a viscometer, and an optical sensor to achieve real-time multi-parameter detection of ink particle size, viscosity, and optical properties, ensuring comprehensive control over ink quality. The detection mechanism is seamlessly connected to the feeding and sorting mechanisms, ensuring a highly efficient and smooth ink flow from feeding to detection and sorting. The PLC controller automatically controls the electromagnetic diversion valve based on the detection data, precisely guiding the ink into the corresponding storage tank and preventing mixing. This combination of automation, multi-parameter detection, and sorting significantly improves production efficiency and ink quality stability, making it particularly suitable for high-precision circuit board printing. Compared to traditional single-parameter detection and manual sorting, this device reduces human intervention and operational errors, providing reliable technical support for large-scale production and meeting the stringent requirements of the modern electronics industry for high-quality inks.

[0014] 2. The feeding mechanism of this utility model is equipped with a filter screen and a flow control valve, effectively improving the quality and stability of ink input. The filter screen, located at the outlet of the feed hopper, removes impurities and large particles from the ink, protecting downstream testing equipment and improving testing accuracy. The flow control valve precisely regulates the ink flow rate, ensuring a stable amount of ink entering the testing mechanism and avoiding testing errors or equipment blockage caused by flow fluctuations. Compared with existing feeding systems lacking filtration and flow control, this device significantly improves the initial quality of the ink and reduces the burden on subsequent processing stages. Simultaneously, the filter screen facilitates maintenance and replacement, reducing equipment maintenance costs and providing a guarantee for continuous production, making it particularly suitable for demanding production environments.

[0015] 3. This utility model's classification mechanism, through an electromagnetic diversion valve and a storage tank connected by a flexible hose, achieves intelligent classification and flexible storage of inks. The electromagnetic diversion valve, driven by a PLC controller, automatically allocates ink flow based on detection data, ensuring accurate classification and storage of inks with different properties and preventing mixing. The flexible hose connection to the storage tank increases the device's layout flexibility, facilitating adjustments to the tank's position according to production needs. The drain pipe and valve equipped in the storage tank facilitate cleaning and ink output, simplifying maintenance. Compared to existing classification methods relying on manual or simple mechanical diversion, this device significantly improves classification efficiency and accuracy, reduces manual operation costs, is suitable for diverse ink production needs, and enhances the device's practicality and industrial application value.
