[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0029] For an example, please refer to... Figures 1-4The laser etching assembly includes a vertical plate 2 and a first linear module 401 mounted on the front of the vertical plate 2. A second linear module 402 is connected to the first linear module 401. A first mounting plate 405 is provided on the second linear module 402. A protective cover 404 is provided on the front of the first mounting plate 405. A projection structure located inside the protective cover 404, detection structures located on both sides of the projection structure, and a laser etcher 414 are also provided on the front of the first mounting plate 405. By using the first linear module 401 and the second linear module 402 to handle the horizontal and vertical movements respectively, this application significantly improves the flexibility of the processing path. The detection structure can monitor the workpiece status in real time during processing to ensure processing quality, while the projection structure projects the processing path onto the workpiece in advance, which facilitates improved processing accuracy.
[0030] Furthermore, a second guide rail 403 is installed on the front of the upright plate 2. A second slide block is slidably connected to the outer surface of the second guide rail 403, and the second slide block is connected to the second linear module 402. The second slide block and the second guide rail 403 cooperate with each other to limit the horizontal movement of the second linear module 402, so as to improve the stability of the second linear module 402 during horizontal movement.
[0031] Furthermore, the projection structure includes a projection module 406 mounted on the front of the first mounting plate 405. The projection module 406 is connected to a projection lens 416, and the projection lens 416 is connected to a projection focusing tube 411. The projection module 406 can project the processing path through the projection lens 416 and the projection focusing tube 411, while the projection focusing tube 411 can extend and retract to achieve focusing.
[0032] Furthermore, a projection reflector 413 is mounted on the front of the first mounting plate 405. The projection reflector 413 is located below the projection focusing tube 411, and the laser etcher 414 is located on the side of the projection reflector 413. The projection reflector 413 is used to reflect the processing path projected by the projection module 406 onto the workpiece so as to display it on the workpiece. The mark at point C in the figure is the projection indication of the processing path.
[0033] Furthermore, an upper fixing plate 407 and a lower fixing plate 409 are fixedly sleeved on the projection focusing cylinder 411. A connecting screw 408 is fixedly installed on the top of the lower fixing plate 409. The top end of the connecting screw 408 passes through the upper fixing plate 407. The connecting screw 408 can connect the lower fixing plate 409 and the upper fixing plate 407 together.
[0034] Furthermore, a spring 410 is sleeved on the outer surface of the connecting screw 408. The spring 410 is located between the upper fixed plate 407 and the lower fixed plate 409. When the force of the spring 410 can drive the projection focusing cylinder 411 to extend and retract, it can buffer the upper fixed plate 407.
[0035] Furthermore, a third linear module 415 is mounted on the front of the first mounting plate 405. The third linear module 415 is connected to the lower fixing plate 409. The third linear module 415 can drive the projection focusing cylinder 411 to extend and retract through the lower fixing plate 409 to achieve focusing.
[0036] Furthermore, a third guide rail 412 is mounted on the front of the first mounting plate 405. A third slide block is slidably connected to the outer surface of the third guide rail 412, and the third slide block is connected to the lower fixed plate 409. The cooperation between the third guide rail 412 and the third slide block can limit the lower fixed plate 409, thereby improving the stability of the lower fixed plate 409 during lifting and lowering, and thus improving the stability of the projection focusing cylinder 411 during extension and retraction.
[0037] Furthermore, the detection structure includes a second mounting plate 417 fixedly installed on the side of the first mounting plate 405. A fixed seat 418 is fixedly installed on the front of the second mounting plate 417. A sliding seat 419 is slidably connected to the inner wall of the fixed seat 418. A fine-tuning scale 420 is connected between the sliding seat 419 and the fixed seat 418. A visual inspection camera 421 is installed on the front of the sliding seat 419. The fine-tuning scale 420 is a micrometer. By rotating the fine-tuning scale 420, the visual inspection camera 421 can be moved up and down to achieve fine-tuning of the visual inspection camera 421.
[0038] A side plate 422 is installed at the bottom of the sliding base 419. A laser reflector 423 located below the vision inspection camera 421 is installed on the side plate 422. Light sources 424 are installed on both sides of the side plate 422. The laser reflector 423 is used to refract the image acquisition path of the vision inspection camera 421 so that the vision inspection camera 421 can obtain the processing status of the workpiece. The light source 424 is used for supplementary lighting. An opening is provided on the front of the protective cover 404. The position of the opening corresponds to the position of the laser reflector 423, the projection reflector 413, the laser etcher 414 and the light source 424, thereby preventing the protective cover 404 from affecting the use of the laser reflector 423, the projection reflector 413, the laser etcher 414 and the light source 424.
[0039] In use, taking the processing of a screen as an example, the screen is set vertically with the etched surface facing the protective cover 404. The projection module 406 projects the processing path onto the projection mirror 413 through the projection lens 416 and the projection focusing tube 411. The projection mirror 413 refracts the processing path onto the screen. The laser etcher 414 etches the screen along the processing path. During the etching process, the visual inspection camera 421 collects the etching information to perform inspection.
