Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a servo laser engraving jig. Background Art

[0002] Laser engraving is a processing method that uses laser technology for engraving, also known as laser engraving. It uses a high-energy laser beam to process the surface of the workpiece. The high energy of the laser beam is concentrated to a very small area, causing the surface of the workpiece to evaporate or melt due to heat, thereby forming the required pattern or text on the surface of the workpiece to achieve the purpose of engraving. Currently in production and processing, people will use laser engraving jigs for laser engraving and marking. Specifically, the jig is used to fix the workpiece so that the part of the workpiece that needs to be processed can be completely exposed within the range of the laser laser.

[0003] Existing laser engraving jigs usually use simulation jigs to fix the workpiece. During processing, the workpiece is put on the simulation jig, and the simulation jig is driven to move by a moving mechanism during processing. For example, Chinese patent publication number CN215615881U discloses "a new type of laser engraving jig", which is provided with multiple profiling jigs for fixing headphones on the gear row, and the servo motor drives the moving mechanism to accurately move each profiling jig to the corresponding position for laser engraving. One clamping can laser engrave multiple headphone products. During the specific operation, the second product is disassembled and assembled when the first product is laser engraved, and the third product is disassembled and assembled when the second product is laser engraved, and the cycle is repeated in sequence, thereby increasing the laser engraving efficiency, improving the laser engraving capacity, and reducing the production cost of the enterprise;

[0004] In actual use, when laser engraving a long workpiece, the laser engraving area of ​​the workpiece is long and narrow, and the origin and starting point length need to be set according to the actual situation of the workpiece. The existing profiling jig is difficult to meet the precision required by the laser engraving process for narrow and long areas during laser engraving, resulting in defects in the produced products.

[0014] Furthermore, the mounting seat is fastened to the adjustment slot by bolts, and a sensing part cooperating with the sensing switch is fixedly arranged on the moving platform.

[0015] The servo laser engraving jig proposed by the utility model has the following beneficial effects:

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A servo laser engraving fixture comprises a fixing part 1 connected to a laser engraving equipment frame and a mounting plate 3 for fixing a workpiece 2. The fixing part 1 is connected to a moving platform 5 through a moving mechanism 4. One side of the moving platform 5 is connected to the mounting plate 3 through a connecting frame 6. The mounting plate 3 is provided with a negative pressure adsorption hole corresponding to the workpiece 2. The negative pressure adsorption hole is externally connected to an air pump for extracting negative pressure.

[0025] The moving mechanism 4 includes a shell 41 fixedly arranged on one side of the fixed part 1, a servo motor 42 is fixedly arranged on one side of the shell 41, an adjustment slot 44 is fixedly arranged at the lower end of the shell 41, a mounting seat 45 is slidably arranged in the adjustment slot 44, and an induction switch 46 is fixedly arranged on the mounting seat 45.

[0026] In the utility model, the workpiece 2 is fixed by the negative pressure adsorption hole, and the positions of the mounting seat 45 and the induction switch 46 are changed. The moving trajectory of the movable platform 5 and the workpiece 2 can be limited by multiple induction switches 46, and the workpiece 2 is operated accordingly when the workpiece 2 moves to a suitable position, and the origin, starting point length, spacing length, etc. are set. A long-distance movement can be divided into multiple short-distance movements, so that laser engraving can be performed in sections. The workpiece 2 can be stopped during each section of laser engraving to ensure the quality of the laser engraving of each part and prevent defects.

[0027] Furthermore, in this embodiment, the output shaft of the servo motor 42 extends into the interior of the housing 41 and is fixedly connected with a screw rod. The servo motor 42 and the housing 41 are detachably connected via bolts, and one end of the screw rod away from the servo motor 42 is rotatably connected to the housing 41 .

[0028] Furthermore, in this embodiment, a slide groove 43 matching with the moving platform 5 is opened on the shell 41, one side of the moving platform 5 is inserted into the slide groove 43 and is threadedly connected to the screw, and the screw is driven to rotate by the servo motor 42, thereby driving the moving platform 5 and the workpiece 2 to move. The use of the servo motor 42 to drive makes the moving process more controllable and precise.

[0029] It should be noted that, in some embodiments, a fixing mechanism 7 that cooperates with the workpiece 2 is provided on the mounting plate 3, and the fixing mechanism 7 includes a fixing frame 71 fixedly arranged on the mounting plate 3 and cooperates with the workpiece 2. A plug-in portion 21 that cooperates with the fixing frame 71 is provided on the workpiece 2, and a nut 22 that cooperates with the fixing frame 71 is threadedly connected on the plug-in portion 21. The plug-in portion 21 and the nut 22 cooperate with the fixing frame 71 to fasten the workpiece 2 to the fixing frame 71 to prevent the workpiece 2 from falling off due to insufficient adsorption force of the negative pressure adsorption hole.

[0030] In addition, in this embodiment, two connecting plates 31 that cooperate with the connecting frame 6 are fixedly provided on one side of the mounting plate 3 close to the connecting frame 6.

[0033] Working method: When working, the workpiece 2 is fixed by the negative pressure adsorption hole, and the workpiece 2 is fastened to the fixed frame 71 by the plug-in part 21 and the nut 22 cooperating with the fixed frame 71 to prevent the workpiece 2 from falling off due to insufficient adsorption force of the negative pressure adsorption hole. The screw is driven to rotate by the servo motor 42, thereby driving the movable platform 5 and the workpiece 2 to move. The moving trajectory of the movable platform 5 and the workpiece 2 can be limited by multiple induction switches 46. When the workpiece 2 moves to a suitable position, corresponding operations are performed, and the origin, starting point length, spacing length, etc. are set. A long-distance movement can be divided into multiple short-distance movements, so that laser engraving can be performed in sections. When fixing the mounting seat 45, the bolt is rotated so that its upper end abuts against the adjustment slot 44 to increase friction, thereby fixing the mounting seat 45.
