Description

Technical Field

[0001] The present invention relates to the technical field of polishing equipment, and in particular to a mechanical arm automated polishing equipment and process for optical element processing. Background Art

[0002] Optical elements are the basic components of optical systems. They are devices that can change the propagation direction, intensity, wavelength, phase and other characteristics of light. Common types include lenses, prisms, reflectors and filters. They are mainly used in optical instrument manufacturing, lighting systems, communications, medical and other fields.

[0003] Among them, the robotic arm automated polishing equipment for optical component processing is an automated device used to perform high-precision polishing on optical components. It is generally composed of a robotic arm part, a polishing tool, and a control system. The optical component to be polished is fixed on a workbench, and then the motion trajectory, polishing speed, polishing pressure and other parameters of the robotic arm are set in the control system according to the shape and polishing requirements of the optical component. The robotic arm moves the polishing tool to the surface of the optical component to start polishing. During the polishing process, the polishing tool is driven by the robotic arm to grind on the surface of the optical component at a certain speed and pressure.

[0004] Most of the existing robotic arm automated polishing equipment will generate a large amount of dust during the polishing process of optical components. The dust generated during the polishing of materials is not collected in a timely manner, which in turn degrades the surrounding working environment and affects the health of the workers. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a robotic arm automated polishing equipment and process for optical element processing to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automated polishing device and process for optical element processing using a robotic arm, comprising a robotic arm body and a polishing wheel, wherein a polishing assembly for processing materials is movably mounted at one end of the robotic arm body, the polishing assembly comprising a protective cover, a fixed plate, and a support plate, a drive motor is arranged inside the polishing assembly, and a polishing wheel and a belt are mounted at the output end of the drive motor, a reverse fan is arranged at the other end of the belt, and a connecting tube is sleeved on the outer wall of the reverse fan, a fixing plate is arranged at one end of the connecting tube, and a supporting plate is arranged at one end of the fixing plate, and cavities are arranged at both ends of the support plate.

[0007] By adopting the above technical scheme, the working environment of the equipment is improved and the impact on the health of the staff is reduced. Secondly, while the driving motor drives the polishing wheel to work, the reverse fan is driven to rotate synchronously through multiple sets of belts to absorb the dust on the surface of the material and reduce the accumulation of dust on the surface of the material. Through the setting of the fixed plate and the support plate, the support plate is located on the inner wall of the protective cover, and the outer wall of the protective cover is provided with a collecting bag. The dust passes through the connecting tube and the cavity and flows into the collecting bag. The limiting groove fits with the protrusion to effectively limit the collecting bag and prevent the collection bag from displacement. The dust is effectively collected in a targeted manner and it is also convenient for the staff to replace the collecting bag regularly, which improves the work efficiency while reducing the accumulation of dust in the polishing component and prolonging the service life of the equipment.

[0008] Furthermore, the connecting tube is provided on the inner wall of the fixing plate, and the cavity is sleeved on the outer wall of the connecting tube.

[0009] By adopting the above technical solution, the cavity is sleeved on the outer wall of the connecting tube, so that the dust in the connecting tube can quickly flow into the collecting bag, reducing the leakage of dust. Secondly, an air outlet is arranged in the protective cover.

[0010] Furthermore, a limiting groove is provided at one end of the fixing plate close to the supporting plate, and a metal layer is provided in the limiting groove.

[0012] Furthermore, a plurality of groups of protrusions are arranged at one end of the support plate close to the fixed plate, and the material of the protrusions is a magnetic block, and the protrusions are engaged with the limiting grooves.

[0013] By adopting the above technical solution, the electric push rod makes the support plate with the material receiving bag moved toward one end of the fixed plate, so that the protrusion is located in the limiting groove, and the magnetic force is generated between the limiting groove and the protrusion to fit tightly, thereby effectively limiting the position of the material receiving bag.

[0014] Furthermore, electric push rods are provided at both ends of the fixing plate, and one end of the electric push rod is connected to the outer wall of the support plate, and a material receiving bag is sleeved on the outer wall of the support plate, and the material of the material receiving bag is non-woven fabric.

[0015] By adopting the above technical solution, the non-woven fabric is a needle-punched felt, which is formed by combing short fibers into a web and then repeatedly piercing the fiber web with barbed needles to make the fibers entangled and reinforced with each other. There are many tiny pores between the fibers inside the needle-punched felt, and these pores allow air to pass freely, thereby ensuring good air permeability, reducing dust leakage, and extending the service life of the equipment.

[0016] Furthermore, a limiting cylinder is movably mounted on one end of the protective cover, a positioning plate is disposed on the inner wall of the limiting cylinder, and an observation port is disposed on one end of the protective cover.

[0017] By adopting the above technical solution, the staff can observe the amount of dust in the collecting bag through the observation port, replace the collecting bag in time, collect the dust in a targeted manner, and improve work efficiency.

[0018] Furthermore, the positioning plate is provided with a plurality of groups of through holes around the reverse blower, and the plurality of groups of through holes form a circular ring shape.

[0019] By adopting the above technical solution, the dust on the surface of the material is adsorbed by setting a plurality of groups of through holes.

[0047] A process for using a mechanical arm automated polishing device for optical element processing, characterized in that the mechanical arm automated polishing device for optical element processing according to any one of claims 1 to 8 is used, and the process comprises the following steps:

[0052] The working principle of the present invention is:

[0053] When the equipment is needed to polish the surface of an optical element, the material is first placed on the workbench, and then the control button is activated so that the polishing assembly 2 is located on the outer wall of the material. The output end of the driving motor 23 drives the polishing wheel 3 to rotate to polish the surface of the material. At the same time, two sets of belts 24 are provided on the output end of the driving motor 23, which in turn drives the rotation of the reverse fan 25 to absorb the dust on the surface of the material.

Secondly, the staff can observe the amount of dust in the material receiving bag through the observation port 29, replace the material receiving bag in time, collect the dust in a targeted manner, and reduce the phenomenon of dust adhering to the parts in the polishing component 2, which not only improves the service life of the polishing component 2, but also improves the work efficiency.
