Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide laser cutting equipment, in particular to an external light path detection system for laser cutting equipment. Background Art

[0002] In CO2 laser cutting equipment, laser radiation is generated by a CO2 laser and focused by a reflector into a high-energy-density laser beam that is then irradiated onto the surface of the material for cutting. Existing CO2 laser cutting equipment typically consists of a frame with a workbench fixed to the frame, on which the laser is mounted and on which the workpiece is placed. Directly above the workbench is an optical system consisting of a cutting table fixed to the frame and movable in the X, Y, and Z axes. The cutting table is fixed with several reflector adjustment mounts for mounting the reflectors and a laser head for mounting the lens. The laser head is connected to the cutting table via a connector, which is threaded into the connector. During CO2 laser cutting equipment installation, a layer of paper tape is applied to the center of the reflector mount (also the center of the reflector). The laser is briefly activated, causing the laser light to mark a black dot on the paper tape. The laser is then turned off, and the operator adjusts the reflector adjustment mount based on the location of the black dot. This installation method is very time-consuming and requires a high level of operator experience. Furthermore, during use, the operator can only determine whether the laser propagation path is correct based on the cut in the material. It is not possible to intuitively understand the propagation path of the laser. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-5As shown, the utility model relates to an external light path detection system for laser cutting equipment, comprising a connecting seat 01 for installing a laser head and a switching device 02 fixedly installed in the frame of the laser cutting equipment. The switching device 02 comprises a support seat 201 fixedly installed on the frame, and two sliding guide rails are installed in parallel in the support seat 201. Two exchange devices 202 of the same structure are fixedly installed on the sliding guide rails, and the two exchange devices 202 are fixedly connected by a connecting plate 204. A test component 203 capable of detecting the external light path is fixedly installed in one of the exchange devices 202, and the other exchange device 202 is used to remove the laser head from the connecting seat 01. A driving component is provided on the support seat 201 for driving the two exchange devices 202 to move synchronously. For example, during the equipment installation and debugging process, the support seat 201 is first fixedly installed in the frame to ensure that the support seat 201 is in a horizontal state, and the connecting seat 01 for installing the laser head is moved to the set position. The drive component moves the exchange device 202, equipped with the test component 203, below the connector 01. The test component 203 is then opened, and the visible laser light generated by the test component 203 is reflected by the reflector inside the connector 01 onto the next reflector. Since the laser light is visible to the naked eye, the reflector position is adjusted by quickly moving it according to the laser's landing point. The final landing point of the laser is aligned with the position of the laser emitting the invisible laser light. This completes the adjustment of all the reflectors. Compared to traditional adjustment methods, this method is faster and more accurate. For example, if the laser path needs to be checked during operation or after a period of operation, the drive component simply moves the exchange device 202, without the test component 203, to the bottom of the connector 01. The laser head is then removed from the connector 01 via the exchange device 202. Then, move the exchange device 202, which holds the test component 203, directly below the connector 01. Install the test component 203 into the connector and turn on the laser. By directly observing the laser's impact point on each reflector, it's possible to clearly and directly determine whether the current reflector position needs to be adjusted. This also allows for quick identification of changes in the external laser system and laser positions, enabling timely adjustments.

[0022] See also Figure 1-3The exchange device 202 shown in FIG. 5 includes a fixed plate 205 fixedly mounted on a sliding guide rail on a support base 201. A mounting hole is located at the center of the fixed plate 205. A hollow connecting rod 206 is disposed within the fixed plate 205. The connecting rod 206 is connected to the mounting hole via a bearing and is rotatably mounted within the mounting hole. The top of the connecting rod 206 is welded to a carrier plate 207. Gears 208 are evenly distributed along the outer circumference of the carrier plate 207. A drive motor is fixedly mounted on the fixed plate 205 to drive the carrier plate 207. A drive wheel is fixedly mounted on the output end of the drive motor, meshing with the gears 208. The drive motor drives the carrier plate 207 to rotate. A guide post 209 is fixedly mounted in the center of the carrier plate 207. A guide hole is defined within the post 209. A mounting slot 210, which connects to the guide hole, is located on one side of the post 209. A notch 211, also connected to the guide hole, is located on the other side of the post 209. The notch 211 and mounting slot 210 are positioned relative to each other on the post 209. A guide shaft 212 is positioned within the guide hole. A rack 213 and a sliding guide rail are fixedly mounted on either side of the guide shaft 212. The rack 213 is positioned within the notch 211, and the sliding guide rail is positioned within the mounting slot 210. A drive motor is fixedly mounted on the carrier plate 207. A power wheel 214 is fixedly mounted at the output end of the drive motor. The power wheel 214 and the rack 213 are meshed and connected. The drive motor drives the power wheel 214 to rotate, thereby moving the guide shaft 212 up and down within the guide hole along the sliding guide rail. The sliding guide rail and the rack 213 positioned within the notch 211 prevent the guide shaft 212 from rotating during its upward and downward movement. The center of the guide shaft 212 is provided with a receiving hole for accommodating the laser head and the test component 203. A positioning plate 215 is fixedly mounted on the top of the guide shaft 212. Two symmetrically arranged positioning members are fixedly mounted on the positioning plate 215. These positioning members comprise a hollow positioning sleeve 216 fixed to the positioning plate 215. The positioning sleeve 216 is equipped with a positioning rod 217. One end of the positioning rod 217 passes through the positioning plate 215 and the other end is located within the positioning sleeve 216. A spring 218 is located within the positioning sleeve 216. One end of the spring 218 abuts against the bottom of the positioning sleeve 216 and the other end abuts against the positioning rod 217. During use, when the laser head is threaded into the connecting base 01, the drive motor on the supporting plate drives the guide shaft 212 upward, positioning the laser head within the receiving hole. The laser head then passes through the positioning members and into the laser head. The motor on the support base 201 then drives the supporting plate 207 to rotate, thereby rotating the guide shaft 212 and the laser head together. During the rotation process, the drive motor on the carrier plate drives the guide shaft 212 and the laser head downward. It should be noted that controlling the simultaneous movement of the two drive motors and controlling their different speeds can be accomplished through a PLC or single-chip microcomputer. Both PLCs and single-chip microcomputers are currently available and will not be described in detail. The laser head is then removed from the connector 01.Similarly, the exchange device 202, equipped with the test component 203, employs the same principle. This allows the test component 203 to be installed in the connector 01 for optical path testing and adjustment. When adjustment and testing are not required, laser heads of different models and specifications can be placed in the two exchange devices 202, achieving automatic laser head replacement. The operator only needs to place the adjusted laser head in the exchange device 202; manual replacement is not required.

[0023] See also Figure 4 The connecting seat 01 shown is provided with a threaded hole for installing the laser head. Four lifting parts 220 with the same structure as the above-mentioned positioning parts are evenly distributed on the bottom of the connecting seat 01, and a fixing ring 221 is fixedly installed on the laser head. A positioning hole 222 adapted to the positioning rod 217 is provided on the fixing ring 221. When the laser head is threadedly connected to the connecting seat 01, the lifting part 220 generates a downward thrust. This prevents the laser head from loosening during operation. At the same time, when the exchange device 202 installs the laser head into the connecting seat 01, it plays a role of buffering and position judgment. It should be noted that when there is no external thread on the outer circumferential surface of the laser head, an adapter sleeve is fixedly connected to the laser head, and an external thread is provided on the outer cylindrical axis of the adapter sleeve, and the laser head can also be threadedly connected to the connecting seat 01.

[0024] The test component 203 includes a connecting column 223 threadedly connected to the connecting seat 01, and the connecting column 223 is vertically mounted with a laser pen 224. The laser pen 224 can be a red laser pen 224, a green laser pen 224, a blue laser pen 224 or a blue-violet laser pen 224.

[0025] The driving component includes a drive screw 225 rotatably mounted on the support base 201 through a bearing. The drive screw is sleeved with an adapted drive nut 226, which is fixedly connected to the connecting plate 204. A drive motor is fixedly mounted on the support base, and the drive motor and the drive screw 225 are connected by a synchronous belt transmission.
