Description

Technical Field

[0001] The utility model relates to the technical field of metal 3D printing, in particular to a telescopic rod type cleaning structure for metal 3D printing equipment. Background Art

[0002] With the large-scale SLM (Selective Laser Melting of Metal) metal 3D printing equipment, the printing cycle of a workpiece may exceed one month. During this long printing process, the accumulation of smoke and dust will contaminate the optical path lenses, which in turn affects the transmission efficiency of laser energy and the printing quality. In addition, the location of the optical path lenses is usually outside the wiping range of the door gloves, making it difficult to effectively wipe and clean them without opening the door. This limitation not only increases the complexity of maintenance work, but also may lead to frequent shutdowns for maintenance, seriously affecting printing efficiency and production progress. Therefore, solving the problem of smoke and dust pollution of the optical path lenses during printing and effectively cleaning the lenses without interrupting printing and opening the door have become the key to ensuring the normal operation of large-scale SLM metal 3D printing equipment.

[0003] Therefore, it is particularly important to design a device that can clean the lens without opening the door. Utility Model Content

[0004] The utility model aims to provide a telescopic rod type cleaning structure for metal 3D printing equipment to solve the technical problem that it is difficult to clean the optical path lens after it is contaminated by smoke and dust during the printing process.

[0005] To achieve the above-mentioned purpose, the utility model provides a telescopic rod cleaning structure for metal 3D printing equipment, comprising a sponge ball and a telescopic rod. The sponge ball is fixed to the head of the telescopic rod and is used to clean the optical path lens. The telescopic rod comprises a plurality of sections, namely a first section rod, a second section rod, a third section rod and a fourth section rod, the first section rod being fixedly connected to the sponge ball, and being stretched section by section through door gloves to achieve different lengths, thereby realizing the cleaning of the optical path lens.

[0006] The multi-section rod design enables effective cleaning of the optical path lenses. The telescopic rod can be stretched section by section to different lengths as needed, so that it can flexibly meet the cleaning needs of optical path lenses at different locations, solving the problem of difficulty in cleaning the optical path lenses after they are contaminated by smoke and dust during the printing process.

[0007] The sponge ball is fixed at the head of the telescopic rod. The sponge material is relatively soft and has good deformation ability. It can effectively remove smoke and dirt on the surface of the optical path lens during the cleaning process. At the same time, it is not easy to scratch the lens, thus ensuring the integrity and service life of the lens.

[0008] By cleaning without opening the door, frequent downtime for maintenance is avoided, thereby improving the operating efficiency of metal 3D printing equipment. The lens can be cleaned without interruption during printing, ensuring the continuity and stability of the printing process, significantly improving production efficiency and product quality.

[0009] The telescopic rod cleaning structure designed in this utility model is easy to operate. It can be stretched section by section through the control of the door gloves, which can quickly and conveniently perform cleaning operations, reducing the maintenance workload and complexity. Operators can perform equipment maintenance without complex training, greatly reducing maintenance costs and manpower investment.

[0010] The telescopic rod comprises a plurality of sections, and the diameters increase successively, so that the telescopic rod has good scalability and flexibility, and can adapt to different equipment and different cleaning requirements.

[0011] By regularly and effectively cleaning the optical path lenses, the obstruction of laser energy transmission caused by smoke pollution is avoided, the loss and failure rate of equipment components are reduced, the service life of metal 3D printing equipment is extended, and the maintenance and replacement costs of equipment are reduced.

[0012] Preferably, the sponge ball is a spherical shape that is relatively soft and has strong deformability, so as to effectively clean the lens without scratching it. Since the sponge ball is relatively soft and has good deformability, it can be closely attached to the surface of the optical path lens during the cleaning process, thoroughly removing smoke and pollutants, while not easily scratching the lens, thus ensuring the integrity and service life of the lens.

[0013] Preferably, the first section of the rod is embedded in the sponge ball.

[0014] The first section of the rod is embedded in the sponge ball, and the connection between the sponge ball and the telescopic rod is more stable, avoiding loosening or falling off during the cleaning process, ensuring the smooth progress of the cleaning work, and improving the cleaning efficiency and effect.

[0015] The telescopic rod cleaning structure for metal 3D printing equipment provided by the utility model has the following advantages:

[0016] The telescopic rod cleaning structure for metal 3D printing equipment provided by the utility model can effectively clean the optical path lens. Through the design of the multi-section rod, the optical path lens can be flexibly cleaned, and the problem of difficult cleaning caused by smoke pollution is solved. The sponge ball is soft and has good deformation ability. It will not scratch the lens during the cleaning process, ensuring the integrity and service life of the lens. Cleaning work is carried out without opening the door, avoiding frequent shutdowns for maintenance, improving the operating efficiency of the printing equipment, ensuring the continuity and stability of the printing process, and significantly improving production efficiency and product quality. It is easy to operate, and the door gloves can be used to control the stretching section by section, which simplifies maintenance work and reduces maintenance costs and manpower investment. The telescopic rod has strong adaptability, is suitable for different equipment and cleaning requirements, and is widely used in large-scale industrial and smaller-scale laboratory equipment. The optical path lens can be cleaned regularly and effectively, avoiding the influence of smoke pollution on laser energy transmission, reducing the loss and failure rate of equipment components, extending the service life of the equipment, and reducing maintenance and replacement costs.
