Description

Technical Field

[0001] This utility model pertains to cleaning devices for optical production equipment, and in particular to a fresh air protection device for keeping optical equipment clean. Background Technology

[0002] Currently, dust is inevitably generated during factory production and processing. This dust floats in the air, and some components require cleaning to prevent dust contamination. However, due to various reasons, complete sealing to completely isolate dust is not possible, such as protective lenses and optical sealing chambers in laser equipment. Dust contamination in these areas can cause white spots on optical components, reduce the power of the laser used in final processing, and thus affect processing results, leading to defective products. To avoid defective products caused by dust contamination during production, frequent shutdowns and manual cleaning of contaminated components are necessary. This significantly reduces production efficiency, increases labor costs, and the constant dust contamination of components can also greatly shorten their lifespan. While exhaust ventilation systems are used to ventilate the production space, the problem of not being able to completely remove all dust remains. Utility Model Content

Detailed Implementation

[0013] The present invention will now be described in more detail through specific embodiments. These embodiments are intended to provide a further understanding and explanation of the present invention, and are for descriptive purposes only, and do not constitute any limitation on the scope of protection of the present invention.

[0014] A fresh air protection device for maintaining the cleanliness of optical equipment includes a housing 1, a vortex fan 6, a filter unit, an air outlet seat 3, an air outlet connector 4, and an airflow distribution pipe 5. The housing is a square frame, closed at the bottom and sides, and open at the front and back, with the air outlet seat fixedly installed at the top. The vortex fan is installed inside the housing. The vortex fan manufacturer and model is Delta 5020 blower 24V. The filter unit includes a first filter unit and a second filter unit symmetrically arranged on both sides of the vortex fan. The first filter unit is arranged on one side of the vortex fan inside the housing. The first filter unit includes a first primary filter 7 and a first secondary filter 8. The first primary filter is located near the air inlet of the housing, and the first secondary filter is located between the first primary filter and the vortex fan. A second filter unit is fixedly installed on the other side of the housing. This second filter unit includes a second pre-filter 11, a second medium-efficiency filter 10, and a medium-efficiency filter holder 9. The medium-efficiency filter holder is fixed to the other air inlet side of the housing. The second medium-efficiency filter is installed inside the medium-efficiency filter holder, and the second pre-filter is fixedly installed on the outer side of the medium-efficiency filter. The pre-filter uses a dustproof mesh, and the medium-efficiency filter uses a circular filter element. A waterproof connector 2 is made on the side of the housing, which connects to the vortex fan control circuit.

[0015] An air outlet mount is installed on the top of the outer casing, and several air outlet connectors are provided on the air outlet mount. Airflow distribution pipes are connected to the air outlet connectors. This embodiment includes two air outlet connectors, which are rotatable. The air outlet connector model is KQ2L10-03S (brand: SMC). The airflow direction of the air outlet connectors is adjustable within a 360-degree horizontal range. The airflow distribution pipe is a PVC air outlet hose, the length of which is adjustable, and the outlet position of the PVC air outlet hose can be adjusted by binding.

[0016] This fresh air protection device can be fixed to a base with relatively clean air, away from the optical component processing equipment, using screws or adhesive. The airflow distribution pipe connected to the outlet connector is led to the location of the optical component, and the airflow distribution pipe is directed towards the optical component using binding or clamping methods. The angle of the outlet connector can also be adjusted to adapt the installation of the PVC air outlet hose to the installation requirements of the processing equipment.

[0017] Outside air enters the device through the fresh air inlet, first passing through a pre-filter that removes larger particles of dust and impurities, such as hair and leaves. Next, the air enters a medium-efficiency filter, which further removes smaller particles of dust, such as pollen and grime. This clean air, filtered through two stages, is then directed by a fan into the airflow distribution ductwork. Through branching ductwork, the air is evenly distributed to each outlet. The clean fresh air blowing from the outlets coats the surfaces of components requiring cleanliness, forming a protective air film that prevents external pollutants from approaching the components, thus maintaining a clean environment.

[0018] During equipment operation, the filtration effect of the air filtration module is continuously monitored, and the pre-filter and medium-efficiency filter are replaced regularly to ensure the normal operation of the device and the cleanliness of the fresh air. At the same time, the speed of the vortex fan can be adjusted appropriately according to the actual cleanliness of the components and the operating requirements of the equipment to change the flow rate and velocity of the fresh air.

[0019] Significant cleaning effect: Through multi-stage air filtration, various pollutants in the air can be effectively removed, providing high-cleanliness fresh air to the components, greatly reducing the impact of pollutants on the components, and improving the cleanliness of the components and the operational stability of the equipment.

[0020] Continuous fresh air supply: The fan operates continuously, ensuring an uninterrupted supply of fresh air and forming a continuous clean airflow barrier. There is no need to stop the machine for cleaning operations, which improves the efficiency of equipment use and production continuity.

[0021] Highly flexible and adaptable: The multiple branches of the airflow distribution duct and the adjustable air outlets can flexibly adjust the supply direction and flow rate of fresh air according to the shape, position and usage requirements of different components, making it widely applicable.

[0022] Although the embodiments and drawings of this utility model have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of this utility model and the appended claims. Therefore, the scope of this utility model is not limited to the contents disclosed in the embodiments and drawings.
