Description

Technical Field

[0001] This invention relates to the fields of precision micro-hole processing and industrial inkjet printhead repair technology, and in particular to a accumulator-type instantaneous impact vacuum unblocking device. Background Technology

[0002] Various industrial inkjet printheads, semiconductor microporous devices, and precision fluid components all possess micron-level microporous structures. Kyocera, Konica, Seiko, Toshiba, Starlight, Ricoh, and the 3200 series are among the most commonly used mainstream industrial printheads. During use, these printheads are easily clogged by dried ink impurities, microparticles, and crystals, causing micropore failure. Existing vacuum cleaning equipment uses a continuous, slow vacuum method, resulting in weak suction that cannot remove stubborn, dried-up blockages deep within the micropores. Conventional ultrasonic cleaning can only clean surface impurities and cannot deeply unclog the pores. Manual drilling can easily enlarge the micropores and damage the hole walls, leading to the direct scrapping of the workpiece.

[0003] Currently, the market lacks specialized equipment that can pre-accumulate pressure and then instantly impact and unclog the blockage after reaching a fixed pressure. Conventional equipment has poor versatility, cannot be adapted to all types of industrial nozzles and various precision microporous devices, and has low maintenance efficiency and high scrap costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a pressure-accumulating instantaneous impact vacuum unblocking device. It pre-accumulates pressure in a spherical tank, and after reaching a set negative pressure, it instantly opens the valve to achieve impact-type suction unblocking. At the same time, it is compatible with conventional slow pumping mode, and is suitable for all types of industrial nozzles and precision micro-hole devices. It has a strong unblocking effect and controllable pressure. It can be used in conjunction with precision micro-hole repair equipment to build a complete micro-hole repair technology system.

[0005] The present invention provides a pressure-accumulating instantaneous impact vacuum unblocking device, including a vacuum pressure gauge (01), a first control valve (02), a second control valve (03), a vacuum pump unit (04), a drain valve (05), a spherical negative pressure tank (06), and a workpiece placement station (10);

[0006] The vacuum pump unit (04) is connected to the spherical negative pressure tank (06) via the second control valve (03). When the first control valve (02) is closed, the vacuum pump evacuates the spherical negative pressure tank (06) to store negative pressure potential energy in advance.

[0007] The vacuum pressure gauge (01) monitors the negative pressure inside the tank in real time. After the pressure reaches the preset fixed value, the first control valve (02) is opened instantly. The spherical negative pressure tank (06) releases the negative pressure potential energy, forming an instantaneous strong impact suction force to peel off stubborn blockage impurities in the micropores.

[0008] The device can switch to a normal slow vacuuming mode. The first control valve (02) is normally open, and the vacuum pump continuously pumps vacuum to achieve smooth unblocking.

[0009] The spherical negative pressure tank (06) adopts a spherical structure, which ensures uniform negative pressure distribution and stable pressure storage;

[0010] The drain valve (05) is used to drain the waste liquid generated during the dredging operation;

[0011] The workpiece placement station (10) can accommodate various industrial nozzles, semiconductor microporous devices, and precision fluid components from Kyocera, Konica, Seiko, Toshiba, Starlight, Ricoh, and the 3200 series, enabling universal operation.

[0012] During operation, place the industrial nozzle or precision micro-hole device to be unclogged at the workpiece placement station (10); close the first control valve (02), turn on the vacuum pump unit (04), open the second control valve (03), and vacuum the spherical negative pressure tank (06) to accumulate pressure; the vacuum pressure gauge (01) monitors the negative pressure inside the tank in real time. After the pressure reaches the set fixed value, the first control valve (02) is opened instantly, and the spherical tank releases the negative pressure potential energy, generating an instantaneous and strong suction force to quickly remove the dried impurities in the nozzle and micro-hole; for mild blockage, the normal mode can be turned on, the first control valve is always open, and the vacuum is slowly drawn to gently unclog the blockage; after the blockage is completed, open the bottom drain valve (05) to discharge the waste liquid.

[0013] Compared with the prior art, this application has at least the following beneficial technical effects:

[0014] 1. The core innovation is the spherical tank pressure storage + fixed pressure instantaneous impact suction, which is different from the conventional continuous slow vacuum pumping, powerfully removes stubborn blockages and greatly improves the unblocking effect;

[0015] 2. Dual-mode switching: instantaneous impact mode is suitable for severe blockages, while regular slow pumping mode is suitable for mild blockages, adapting to different working conditions;

[0016] 3. The spherical accumulator chamber provides uniform and stable negative pressure, with precise and controllable pressure, preventing excessive suction from damaging the nozzle and micropore walls;

[0017] 4. High versatility, compatible with mainstream industrial printheads and semiconductor micro-orifice and precision fluid components from Kyocera, Konica, Seiko, Toshiba, Starlight, Ricoh, and the 3200 series, with a wide range of applications;

[0018] 5. When used in conjunction with precision micro-hole drilling and repair equipment, it forms a complete technical system of "macro-level negative pressure unblocking + micro-level precise repair", with high patent barriers and strong commercial applicability. Attached Figure Description
