Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and more specifically, to a liftable laser protective cover device. Background Technology

[0002] Laser processing utilizes a laser beam of appropriate energy density, focused on the workpiece surface, to scan the target surface, causing physical or chemical changes in the material to achieve the processing purpose. Typically, during processing, the laser's erosive effect on the workpiece surface generates pungent exhaust fumes and fine particles that diffuse into the air, polluting the surrounding environment. Furthermore, the high energy density of lasers poses a risk of eye damage. Currently, most laser processing equipment is open-type, lacking a protective shield and only equipped with protective goggles. Some small laser processing equipment is equipped with a fixed protective shield, but this shield cannot be moved as the processing height changes, resulting in inadequate protection. Therefore, this invention proposes a liftable laser protective shield device. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-4This utility model provides a technical solution: a liftable laser protective cover device, including a frame 10, a base 20 disposed at one end of the frame 10, and a support frame 30 disposed on the frame 10. A head 50 is disposed on the frame 10. Multiple sets of protective cover guide rails 80 are disposed on both the front and rear sides of the head 50. The interior of the head 50 is used to carry laser optical components and electronic components, while the exterior is used to support and fix the protective cover guide rails 80 and other decorative auxiliary parts. The number of protective cover guide rails 80 is at least two sets, and multiple sets of protective cover guide rails 80 are arranged between them. The machine has a protective cover 40 and a damping kit 60 on the machine head 50. The damping kit 60 is used to provide a restoring force to the protective cover 40 to overcome its own weight. Positioning members 70 are provided on both the front and rear sides of the frame 10. The positioning members 70 are used to provide clamping force to the protective cover 40 to prevent the protective cover 40 from springing back upward. The positioning members 70 are installed on the front and rear sides of the frame 10 and are in the form of grooves. When the protective cover 40 reaches the base 20, it can be inserted into the groove and subjected to clamping force to prevent the protective cover 40 from springing back upward and failing to make close contact with the worktable.

[0026] The protective cover guide rail 80 includes a guide rail fixed end 801 and a guide rail moving end 802.

[0027] It should be noted that the fixed end 801 of the guide rail is connected to the machine head 50, and the moving end 802 of the guide rail is connected to the protective cover 40. This is used to realize the directional function of the protective cover 40 moving up and down, in order to improve the reliability and wear resistance of movement.

[0028] In addition, the damping kit 60 includes a kit fixed end 601 and a kit moving end 602. The kit fixed end 601 is connected to the machine head 50, and the kit moving end 602 is connected to the protective cover 40, so that the protective cover 40 can be kept in a suspended state at any position in the working range, which facilitates opening the processing space.

[0029] Meanwhile, the positioning component 70 is provided with a slot 701. The width of the slot 701 is the same as the thickness of the protective cover 40. The clamping force between the slot 701 and the protective cover 40 can be achieved by magnetic attraction or material elastic deformation. The clamping force can prevent the protective cover 40 from automatically rebounding and allow the user to easily lift the protective cover 40.

[0030] It should be emphasized that first rollers 501 are provided on both the front and rear sides of the machine head 50, and second rollers 502 are provided on both the front and rear sides of the machine head 50. The fixed shaft of the rollers is connected to the machine head 50, and the rotating part is always in contact with the protective cover 40. It can rotate around the fixed shaft as the protective cover 40 moves up and down. The second roller 502 is located directly below the first roller 501. The first roller 501 and the second roller 502 are in contact with the inner wall of the protective cover 40 and are used to achieve the auxiliary orientation function of the protective cover 40 moving up and down.

[0031] Specifically, the working principle of this liftable laser protective shield device is as follows:

[0032] During operation, the user first lifts the protective cover 40, which can be suspended at a height slightly higher than the thickness of the workpiece. Then, by raising and lowering the machine head 50, the laser working distance relative to the workpiece is adjusted. After placing the workpiece, the protective cover 40 is pulled down to touch the bottom base 20, where the positioning component 70 holds the protective cover 40 in place, and laser processing begins. During processing, the protective cover 40 can block reflected laser light reaching the workpiece, providing protection for the user. After processing is completed, the user lifts the protective cover 40, suspends it at any position, removes the workpiece, and lowers the protective cover 40, thus completing the entire processing process.

[0033] It should be noted that the specific models and specifications of the protective cover 40, machine head 50, first roller 501, second roller 502, damping kit 60, positioning component 70, and protective cover guide rail 80 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Furthermore, the terms “first,” “second,” “third,” and “fourth” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as “first,” “second,” “third,” or “fourth” may explicitly or implicitly include at least one of those features.
