[0002] The watch mirror is the transparent lens on the surface of the watch, also known as watch glass in the industry, which is used to protect the watch surface (dial). According to the material, the watch mirror can be divided into three categories: plastic mirror, quartz glass mirror, and synthetic sapphire glass mirror. Plastic mirrors are relatively resistant to falling, and synthetic sapphire glass watch mirrors are the most wear-resistant. Laser cutting technology uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby cutting the workpiece.

[0003] The laser cutting equipment currently used in watch mirror processing will generate a lot of smoke and dust during the cutting process, which can easily pollute the processing environment and affect the health of workers. At the same time, since the mirror is a fragile workpiece, the extrusion fixation commonly used during processing can easily cause damage to the lens surface or even the mirror itself.

[0017] The present invention provides a watch mirror laser cutting device, which has the following beneficial effects:

[0018] 1. When using the watch mirror laser cutting equipment, the workpiece is placed in the positioning groove. Since the annular airbag is connected to the external air pump, the annular airbag is inflated by the external air pump, and the annular airbag expands and pushes the arc spring on its inner side to move toward the side of the workpiece. The arc spring drives the extrusion pad to move toward the side of the workpiece, and the extrusion pad can be squeezed to the side of the workpiece by the expansion of the annular airbag. Since multiple groups of extrusion pads are provided, the workpiece can be clamped from multiple directions by the cooperation of multiple groups of extrusion pads and arc springs, which is convenient for fixing the workpiece, and the workpiece is squeezed from the side by the extrusion pad and the arc spring to avoid direct extrusion to the surface of the workpiece and causing damage to the surface of the workpiece. At the same time, the extrusion pad and the arc spring can also protect the workpiece through their own elasticity to avoid damage to the workpiece itself caused by extrusion and other operations. At the same time, through the setting of the extrusion pad and the arc spring, workpieces of different shapes can be adapted under the extrusion of the annular airbag, which is convenient for improving the adaptability of the device.

[0019] 2. When the watch mirror laser cutting equipment is in use, air is extracted from the dust removal device and the annular air pipe through an air pump, so that the air in the external environment enters the interior of the air suction nozzle, enters the interior of the annular air pipe through the air suction nozzle, and then enters the interior of the dust removal device through the exhaust pipe. After dust removal by the dust removal device, it enters the cooling pipe, and the air after dust removal is sent to the interior of the cooling device through the air suction pump on the cooling pipe. The gas is cooled by the cooling device, and the cooled gas enters the interior of the positioning cavity through the connecting pipe, and is discharged from the air hole and blown on the workpiece, so as to facilitate the cooling of the workpiece, so that the workpiece can be quickly removed after the laser cutting is completed, thereby improving the processing efficiency, and will not cause accidental injuries to the staff, and is safer and more reliable to use. At the same time, the smoke on the surface of the workpiece and near the surface can be blown away by the gas discharged from the air hole, so as to prevent the smoke from adhering to the surface of the workpiece, and at the same time, the smoke can be blown to the vicinity of the air suction nozzle, so that the air suction nozzle can better absorb the smoke.

[0020] 3. In the watch mirror laser cutting equipment, when the flue gas enters the dust removal device, it first enters the air inlet from the exhaust pipe, and the gas exhausted from the air inlet is directly blown onto the spherical filter, and the gas can be filtered through the spherical filter. Since the two sides of the spherical filter extend to the ends of the air inlet and the air outlet located inside the dust removal box respectively, the flue gas can be filtered twice through the spherical filter during movement, and the filtering effect is better. At the same time, the rotating motor drives the spherical filter to rotate, and the cleaning motor drives the cleaning brush to rotate, so that the spherical filter gradually passes through the cleaning brush during the rotation, and the surface of the spherical filter can be cleaned by the rotating cleaning brush, which is convenient to avoid the filter from being blocked. There is no need to manually remove and clean the filter, and it is convenient to use.

[0021] 4. In the watch mirror laser cutting equipment, when the smoke is discharged from the dust removal device into the cooling pipe, the gas is sent into the diverter pipe through the air pump on the cooling pipe, and the gas is diverted through the diverter pipe, so that the gas enters the cooling box from different bronchial tubes and contacts with the coolant inside the cooling box. After the gas is cooled by the coolant, the cold air enters the positioning cavity from the connecting pipe on the top of the cooling box and is discharged from the air holes, which is convenient for discharging the gas into the coolant from different positions, so that the coolant at various positions inside the cooling box can contact the gas for heat exchange, which is convenient for achieving a better cooling effect. At the same time, the heat conducting plate can be cooled by the circulation of the coolant in the coolant pipe, and the coolant inside the cooling box can be cooled by the heat conducting plate, so that the coolant inside the cooling box can always maintain a good cooling effect.

After dust removal by the dust removal device 44, it enters the cooling pipe 45, and the dust-removed gas is sent to the interior of the cooling device 46 through the suction pump 47 on the cooling pipe 45. The gas is cooled by the cooling device 46, and the cooled gas enters the interior of the positioning cavity 54 through the connecting pipe, and is discharged from the air hole 55 and blown onto the workpiece, so as to facilitate the cooling of the workpiece, so that the workpiece can be quickly removed after the laser cutting is completed, thereby improving the processing efficiency, and will not cause accidental injuries to the staff, and is safer and more reliable to use.
