A double-seal structure protection structure

Abstract

This utility model discloses a double-sealed protective structure, which relates to the field of laser marking machines. It aims to solve the problem that when too much dust and impurities enter the internal reflective optical path area of ​​a laser marking machine, the reflectivity of optical lenses such as reflective lenses and field lenses decreases significantly, and a large amount of laser light hitting the lenses causes rapid heating, which can easily burn the lenses. The key technical point is that a second sealed housing is installed inside the bottom housing, which is fitted to the lens base and the lens base to cover the laser reflection module. Both the first and second sealed housings are U-shaped and have rubber sealing strips fixed to their outer edges, achieving a double seal to prevent impurities from entering.

Description

Technical Field

[0001] This utility model relates to the technical field of laser marking machines, specifically to a double-sealed protective structure. Background Technology

[0002] Laser marking machines use a laser beam to create permanent marks on the surfaces of various materials. The marking effect occurs by evaporating the surface material to expose the deeper material, thus etching intricate patterns, trademarks, and text. Laser marking machines are mainly classified into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines, and YAG laser marking machines. Laser marking machines are primarily used in applications requiring higher precision and finer details. Applications include electronic components, integrated circuits (ICs), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, eyeglasses and watches, jewelry, automotive parts, plastic buttons, building materials, and PVC pipes.

[0003] The existing technical solutions mentioned above have the following drawbacks: Due to the need for heat dissipation, existing laser marking machines usually have several heat dissipation holes on the surface of the housing, which makes it very easy for external dust and impurities to enter the housing. When too much dust and impurities enter the reflective light path area inside the laser marking machine, the reflectivity of optical lenses such as reflective lenses and field lenses to the laser drops significantly. A large amount of laser light hitting the lens causes a rapid increase in temperature, which can easily burn the lens. Therefore, a highly sealed housing structure is needed to ensure the normal operation of the laser marking machine for a long time. Utility Model Content

[0004] The purpose of this invention is to provide a double-sealed protective structure.

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

[0006] The device includes a bottom housing and a first sealing housing. The first sealing housing is installed to cover and enclose the bottom housing. A power control module, a laser generator, a laser reflection module, and a lens module are fixedly installed on the inner wall of the bottom housing. Heat dissipation holes are provided through the two side walls of the first sealing housing. Vertical power bases and lens bases are fixedly installed at both ends of the bottom housing along its length. A lens base for mounting the laser reflection module is fixedly installed on the inner wall of the bottom housing. The power control module and the laser generator are fixedly installed between the power base and the lens base. The laser reflection module is fixedly installed between the lens base and the lens base. A second sealing housing is installed inside the bottom housing, fitted to the lens base and the lens base, to cover the laser reflection module. Both the first and second sealing housings are U-shaped and have rubber sealing strips fixedly installed on their outer edges. A connecting bolt is installed through the first sealing housing.

[0007] By adopting the above technical solution, the first sealing shell can enclose all internal components, achieving the initial effect of preventing internal components from being damaged. In use, the laser lens of the laser generator is installed on the lens base in conjunction with the lens module. The second sealing shell further seals the laser reflection module. By using the rubber sealing strip to block the seams, it facilitates the installation of internal components while providing a good secondary seal for the most important laser reflection module. This effectively prevents external dust and impurities from entering the laser reflection module and contaminating the reflecting lens and lens, effectively ensuring the normal and stable operation of the internal reflecting lens and lens.

[0008] Furthermore, the first sealing housing is provided with a threaded connection to the bottom housing via a connecting bolt, and the second sealing housing is provided with a threaded connection to the lens base via a connecting bolt. The connecting bolt includes a threaded post and a nut, and a sealing rubber ring is fixedly installed around the threaded post on one side of the nut.

[0009] By adopting the above technical solution, the nut with a sealing rubber ring can deform when tightened to effectively block the gap and prevent external dust and impurities from entering.

[0010] Furthermore, the inner wall of the lens base is fixedly provided with a sealing protrusion that fits against the second sealing shell, and a sealing plate that fits against the second sealing shell extends inside the bottom shell. A threaded sealing plug is provided through the lens base, and one end of the sealing plug extends out of the sealing plate and is fixedly provided with a turning protrusion. A control cable for controlling the laser reflection module is provided through the sealing plug.

[0011] By adopting the above technical solution, the sealing ridge and the sealing plate further cover the gap between the second sealing shell and the lens base and lens base. The sealing plug is a soft plug body. Twisting the ridge makes it easy for the operator to twist the sealing plug. The sealing plug can control the cable contact while effectively sealing the access hole, and has a good sealing effect.

[0012] Furthermore, a magnetic dustproof mesh covering the heat dissipation holes is fitted into the outer wall of the first sealing shell. A protective plastic film is connected to one end of the magnetic dustproof mesh, and magnetic strips are arranged along the length of the outer edge of the protective plastic film.

[0013] By adopting the above technical solution, when the equipment is not started, the protective plastic film flips over to cover the magnetic dustproof mesh. The magnetic strip effectively attracts the magnetic dustproof mesh, achieving a good seal and protecting the edge of the plastic film, thereby effectively sealing the heat dissipation holes and preventing external dust and impurities from entering from here. When in use, the protective plastic film is opened so that the magnetic strip is attracted to the first sealed housing. At this time, the magnetic dustproof mesh covers the heat dissipation holes, which does not hinder heat dissipation while effectively preventing large particles of dust and impurities from entering.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] 1. It adopts a first sealing shell, a second sealing shell, a rubber sealing strip and connecting bolts, which facilitates the installation of internal components and provides a good secondary seal for the most important laser reflection module. This effectively prevents external dust and impurities from entering the laser reflection module and contaminating the reflective lens and lens, thus ensuring the normal and stable operation of the internal reflective lens and lens.

[0016] 2. It adopts a sealing plug and a screw-on protrusion, which facilitates control of cable contact and effectively seals the access holes, providing a good sealing effect;

[0017] 3. It adopts a magnetic dustproof mesh, protective plastic film and magnetic strip. When the equipment is not started, the edge of the protective plastic film is well sealed to effectively seal the heat dissipation holes. When in use, the protective plastic film is opened so that the magnetic strip can be attached to the first sealed shell, which can effectively prevent large dust particles and impurities from entering without hindering heat dissipation.

The first sealing housing 2 can cover all internal components, achieving the effect of initially preventing internal components from being damaged. In use, the laser lens of the laser generator 4 is installed on the lens base 9 and set up in conjunction with the lens module 6. The second sealing housing 10 further seals the laser reflection module 5. By using the deformation of the rubber sealing strip to block the seam, it not only facilitates the installation of internal components but also provides a good secondary seal for the most important laser reflection module 5. This effectively prevents external dust and impurities from entering the laser reflection module 5 and contaminating the reflecting lens and lens, effectively ensuring the normal and stable operation of the internal reflecting lens and lens.
