Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laser paint stripping technology, specifically relating to a laser mirror paint stripping machine. Background Technology
[0002] Mirrors, as a common type of home furnishing, decorative, and industrial product, often require laser peeling of patterns, text, and other information on their coating surfaces to form decorative or functional windows or markings. Existing mirror laser peeling equipment typically uses mechanical pressure plates or simple clamps to fix the mirror surface. However, for thin mirrors, mechanical clamping can easily cause micro-cracks or permanent deformation of the mirror surface due to stress concentration, or even cause hard damage at the clamping point, resulting in low product yield.
[0003] Furthermore, the mirror has a high-gloss reflective film layer and two sides of the coating to be peeled off. Before processing, the operator needs to manually position the mirror and ensure that the front side (coated side) is facing up. This process has two major drawbacks: first, manual positioning is inefficient and inconsistent, affecting processing accuracy; second, if the mirror is placed backwards by mistake, the high-energy laser beam will directly burn the precious reflective film, rendering the mirror unusable and causing economic losses.
[0004] Therefore, there is an urgent need in this field for a new type of laser paint stripping equipment for mirror surfaces that can achieve fast, accurate, and non-destructive clamping and effectively prevent misoperation such as mirror surface reversal. Utility Model Content
[0005] In order to solve the above-mentioned technical problems, this utility model provides a laser mirror paint stripping machine, which has a simple structure, is easy to use, and can achieve fast, accurate and non-destructive clamping, effectively preventing the misoperation of placing the mirror in reverse.
[0006] The technical solution adopted by this utility model is as follows: a laser mirror paint stripping machine, including a frame, a worktable on the frame, a vacuum adsorption system on the worktable, a positioning mechanism on the worktable, the positioning mechanism including two symmetrically arranged first guide rails, the extension directions of the first guide rails being diagonally distributed, each first guide rail being provided with a right-angle limiting block that can slide and lock along it; a gantry frame spanning the worktable is provided on the frame, the gantry frame including second guide rails fixedly arranged on both sides of the frame and a crossbeam mounted on the second guide rails on both sides, the crossbeam being movable along the second guide rails, a third guide rail being provided on the crossbeam, a vertical guide rail being provided on the third guide rail being movable along the third guide rail, a laser head being provided on the vertical guide rail being movable along the vertical guide rail, an anti-reverse installation detection device being provided on one side of the laser head, the anti-reverse installation detection device being a diffuse reflection photoelectric sensor, the optical axis of its detection beam being perpendicular to the surface of the worktable, and a control device being provided at one corner of the frame.
[0007] The vacuum adsorption system includes vacuum adsorption holes on the worktable, which are connected to vacuum pipelines, which in turn are connected to a vacuum pump and a solenoid valve.
[0008] The workbench surface is divided into multiple independent vacuum adsorption areas, each of which is connected to a vacuum pipeline controlled by an independent solenoid valve.
[0009] The right-angle limit block integrates a quick-clamping handle.
[0010] The crossbeam moves along the X-axis, and the laser head moves along the Y and Z axes, both driven by servo motors or stepper motors.
[0011] The control device includes an L-shaped support rod, with one end connected to the machine tool and the other end supporting an industrial computer.
[0012] The beneficial effects of this utility model are as follows: This utility model has a simple structure and is easy to use. It can achieve fast, accurate and non-destructive clamping and effectively prevents the mirror from being placed backwards. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0016] As shown in the figure, a laser mirror paint stripping machine includes a frame 1, a worktable 2 mounted on the frame 1, and a vacuum adsorption system 3 mounted on the worktable 2. The vacuum adsorption system 3 includes vacuum adsorption holes 31 opened on the surface of the worktable 2, which are connected to vacuum pipelines. The vacuum pipelines are connected to a vacuum pump and a solenoid valve. The surface of the worktable 2 is divided into multiple independent vacuum adsorption areas, each of which is connected to a vacuum pipeline controlled by an independent solenoid valve. A positioning mechanism 4 is mounted on the worktable 2. The positioning mechanism 4 includes two symmetrically arranged first guide rails 41, which extend diagonally. Each first guide rail 41 is provided with a right-angle limiting block 42 that can slide and lock along it. The right-angle limiting block 42 integrates a quick-clamping handle. A gantry frame 5 spans the worktable 2 on the frame 1. The gantry 5 includes second guide rails 51 fixedly mounted on both sides of the frame 1 and crossbeams 52 mounted on the second guide rails 51. The crossbeams 52 can move along the second guide rails 51. A third guide rail 53 is mounted on the crossbeams 52. A vertical guide rail 54 that can move along the third guide rail 53 is mounted on the third guide rail 53. A laser head 55 that can move along the vertical guide rail 54 is mounted on the vertical guide rail 54. The crossbeams 52 move along the X-axis, and the laser head 55 moves along the Y-axis and Z-axis, both driven by servo motors or stepper motors. An anti-reverse mounting detection device 6 is provided on one side of the laser head 55. The anti-reverse mounting detection device 6 is a diffuse reflection photoelectric sensor. The optical axis of its detection beam is perpendicular to the table surface of the worktable 2. A control device 7 is provided at one corner of the frame 1. The control device 7 includes an L-shaped support rod 71. One end of the support rod 71 is connected to the machine tool, and the other end supports the industrial computer 72.
[0017] In this laser mirror paint stripping machine, the right-angle limiting block 42 is moved to the appropriate position according to the workpiece requirements. The worker places the workpiece on the worktable 2, and the right-angle limiting block 42 ensures the workpiece's placement. The workpiece is fixed by the vacuum adsorption system 3. The control device 7 starts the equipment, and the anti-reverse mounting detection device 6 detects whether the workpiece is placed backwards. When the workpiece is placed backwards, the anti-reverse mounting detection device 6 transmits an error signal to the industrial computer 72, which issues a warning and the laser head 55 does not start. When the workpiece is placed correctly, the anti-reverse mounting detection device 6 transmits a correct signal to the industrial computer 72. The crossbeam 52, vertical guide rail 54, and laser head 55 move according to the program settings and perform laser mirror paint stripping. After completion, the processed workpiece is obtained. This utility model has a simple structure, is easy to use, and can achieve fast, accurate, and non-destructive clamping, effectively preventing the misoperation of mirror paint being placed backwards.
