Description

Laser cutting equipment

The new invention relates to a component processing device, in particular a laser cutting device.

Laser cutting technology is one of the common operating methods in the processing and manufacturing industry. It is known that laser cutting equipment used to cut large workpieces is usually equipped with a protective cover to prevent operators from being harmed by radiation from the laser light source during the process. The protective cover is usually set above or around the laser light source to block the laser light source from the outside. For example, the protective cover and the laser light source are jointly set on a supporting structure to move synchronously during the cutting process.

Although the aforementioned structural design can effectively prevent the laser light source from causing harm to the operator, the laser device used to cut large workpieces needs to be equipped with a high-power laser light source, which makes the laser device itself very large. Therefore, when the laser device is moving, it often consumes a lot of energy, and the protective cover installed on the laser device further increases the energy loss, making it difficult to reduce the process cost.

Therefore, the purpose of this invention is to provide a laser cutting device suitable for cutting large workpieces to reduce the energy loss of the cutting process.

This new type of laser cutting equipment includes a carrier, a protective cover unit, and a laser cutting unit.

The carrier has at least one working area.

The protective cover unit includes a protective cover, which is located above the working area and corresponds to the entire range of the working area and defines a protective space.

The laser cutting unit is disposed between the protective cover unit and the carrier, and includes a laser source that can be movably positioned in the working area and within the protective space.

The protective cover unit and the laser cutting unit are independent of each other.

The effect of the new invention is that the laser cutting unit and the protective cover unit are independent components, so when the cutting process is carried out, the protective cover does not need to move with the laser source, but only needs to move the laser source, which can reduce the energy loss in the process, and the protective space defined by the protective cover corresponds to the range of the entire working area, so it can still provide sufficient protection.

Figures 1 and 2 are schematic diagrams illustrating an embodiment of the novel laser welding equipment.

The technical content and effects of the present invention will be clearly presented in the detailed description of the accompanying drawings and the following embodiments. It should be noted that the drawings of the present invention are only used to indicate the relative position relationship between components and are not related to the actual size of each component.

Referring to Figures 1 and 2, an embodiment of the novel laser cutting device includes a carrier 10, a protective cover unit 20, and a laser cutting unit 30. The protective cover unit 20 and the laser cutting unit 30 are independent of each other.

The support platform 10 has a plurality of working areas 11 arranged along a longitudinal direction L, for the laser cutting unit 30 to perform laser cutting on a workpiece to be cut (not shown). The support platform 10 is a ground rail device.

The protective cover unit 20 includes a moving part 21 disposed adjacent to the carrier 10, and a protective cover 22 disposed on the moving part 21.

The protective cover 22 is movably located above one of the working areas 11 and defines a protective space 221. The moving member 21 is used to control the displacement of the protective cover 22 so that the protective cover 22 can be moved into or out of the range corresponding to one of the working areas 11 and can be moved along the longitudinal direction L to another working area 11.

In this embodiment, the moving member 21 includes a set of rails spaced apart on opposite sides of the carrier 10 and extending along the longitudinal direction L, which helps the protective cover 22 to move along the rails; a side peripheral wall of the protective cover 22 is formed with two openings 23 spaced apart along the longitudinal direction L, and has two protective doors 24 respectively disposed adjacent to the two openings 23. The two protective doors 24 are automatic rolling doors, which are respectively used to open or close the corresponding two openings 23. When the protective cover 22 moves along the longitudinal direction L, the two openings 23 will open, so that the working area 11 and the workpiece placed on the support table 10 can pass through the two openings 23; when the laser cutting process is performed, the protective cover 22 will be fixed within the range of one of the working areas 11, and at this time, the two openings 23 will be closed through the protective doors 24, so that the protective space 221 is in a closed state.

The laser cutting unit 30 is disposed between the protective cover unit 20 and the support platform 10, and includes a movable support structure and a laser source 32 disposed on the movable support structure. The laser source 32 is driven by the movable support structure so as to be movable to the working area 11 and located in the protective space 221.

Specifically, in this embodiment, the movable support structure is shown in FIG. 2 and comprises two support parts 311 respectively disposed upright at opposite sides of the working area 11, a connecting part 312 connected to the support parts 311, a position adjustment part 314 disposed on the connecting part 312, and a movable part 313 disposed on the support part 311. The laser source 32 is disposed on the connecting part 312 and connected to the position adjustment part 314. The support parts 311 and the connecting part 312 together form a gantry structure and serve as the main supporting structure of the laser cutting unit 30. The moving part 313 has a set of slide rails spaced apart on opposite sides of the support platform 10 and extending along the longitudinal direction L, for driving the gantry structure and the laser source 32 to move along the longitudinal direction L, and the position adjustment part 314 is used to drive the laser source 32 to move within the working area 11 at a relatively small distance (i.e., the moving range is smaller than the working area 11) along at least one of a transverse direction T, a vertical direction and the longitudinal direction L.

The slide rail of the moving part 313 is disposed between the support platform 10 and the rail of the moving member 21. The transverse direction T is orthogonal to the longitudinal direction L and is in the same direction as the extension direction of the connecting part 312; the vertical direction is a direction that is always perpendicular to the working area 11.

It should be noted that the structural design of each component member of the laser cutting unit 30 (such as the support portion 311, the connecting portion 312 and the position adjustment portion 314, etc.) can be changed according to actual needs. For example, the mobile support structure can also be provided with only a single support portion 311 and set on a single side of the working area 11 without the connecting portion 312. As long as the laser cutting unit 30 and the protective cover unit 20 are independent components, it is not limited to the aforementioned embodiments and drawings.

During use, the workpiece will generate dust during the laser cutting process, causing part of the laser light path to be disturbed and diffused, or the laser source 32 will emit laser light of various incident angles when performing the three-dimensional laser cutting process. The protective space 221 defined by the protective cover 22 of this embodiment covers the entire range of the working area 11, thereby effectively protecting the radiation energy and laser light emitted by the laser source 32 to prevent the operator from being injured. In addition, since the laser cutting unit 30 and the protective cover unit 20 are two independent components, the protective cover 22 does not need to move with the laser source 32 during the process, and can effectively reduce the energy consumed in the process while providing sufficient protection.

In some embodiments, the laser cutting device further includes a control unit, which is signal-connected to the protective cover unit 20 and the laser cutting unit 30 respectively, for issuing a command signal. After the laser cutting unit 30 receives the command signal, the mobile support structure can drive the laser source 32 to move along a preset process path to perform laser cutting on the workpiece placed in the working area 11 to form a preset cutting pattern; after the protective cover unit 20 receives the command signal, the mobile member 21 can be moved along the longitudinal direction L to a range corresponding to one of the designated working areas 11, so that the laser source 32 can be located in the protective space 221 when performing the cutting process within the range of one of the working areas 11.

In other embodiments, the carrier 10 may have only a single working area 11, and the protective cover unit 20 may fix the protective cover 22 in a range corresponding to the working area 11 as required, without configuring the moving part 21. During implementation, the laser source 32 may be movably positioned in the protective space 221, saving the energy of moving the protective cover unit 20.

In summary, the novel laser cutting equipment adopts the structural design that the protective cover unit 20 and the laser cutting unit 30 are independent components. Therefore, when the cutting process is performed, the protective cover 22 is set corresponding to the range of the working area 11 for protection without moving. In addition to providing effective protection, only the laser source 32 needs to be moved, thereby reducing energy loss in the process. Compared with a completely open laser cutting machine, it is safer, so the purpose of the novel device can be achieved.
