Description

Laser carving machine Technical Field The invention relates to the technical field of laser engraving machines, in particular to a laser engraving machine. Background The laser engraving is a surface treatment process, similar to screen printing and pad printing, is to print or pattern on a product, and is also called laser engraving, wherein the laser engraving is to make traces by chemical and physical changes of surface layer substances caused by light energy of laser beams, or burn out part of substances by light energy, so as to display graphics and characters to be etched. Traditional laser radium carving machine needs the manual work to carry out the material loading, places the product under the laser instrument, restarts the laser instrument, engraves department figure or characters on the product through the laser instrument, adopts artificial mode to carry out the material loading, and production efficiency is extremely low. In order to solve the problem, some manufacturers design a laser engraving machine capable of grabbing feeding and discharging materials through a manipulator, the laser engraving machine can refer to an automatic laser engraving device disclosed in Chinese patent publication No. CN110682002B, and the automatic laser engraving device comprises a machine table, a material tray, a feeding manipulator, a conversion table, a station assembly, a laser engraving assembly, a horizontal carrying mechanism and a discharging manipulator, wherein the material tray, the feeding manipulator, the conversion table, the horizontal carrying mechanism and the discharging manipulator are arranged on the machine table, the feeding manipulator is used for grabbing to-be-engraved pieces in the material tray onto the conversion table, the station assembly comprises n stations for clamping to-be-engraved pieces, the laser engraving assembly comprises m laser cavities respectively arranged right above the n stations, the horizontal carrying mechanism comprises w clamping jaws for sequentially moving to-be-engraved pieces on the conversion table, and the discharging manipulator is used for grabbing to-be-engraved pieces on the last station onto the discharging tray. Adopt above-mentioned automatic radium carving equipment, can carry out automatic radium carving to the product and process, alleviate artifical intensity of labour, can also improve the work efficiency of radium carving processing simultaneously, be applicable to the processing product in batches. Above-mentioned automatic radium carving equipment, although can realize automatic unloading, material loading and unloading all need pass through the manipulator and shift, and machining efficiency is still not high. Therefore, the laser engraving equipment for conveying the product through the belt is arranged, the product is conveyed to the preset station through the belt, and laser engraving is carried out at the preset station, so that the working efficiency can be effectively improved. Such radium carving equipment can refer to an automatic radium carving machine as disclosed in Chinese patent publication No. CN201931902U, and comprises a frame, a laser machine, a radium carving jig, a numerical control system arranged on the frame and an automatic feeding transmission mechanism, wherein the laser machine and the radium carving jig are arranged on the frame, the laser machine is positioned right above the radium carving jig, the laser machine is electrically connected with the numerical control system, and the automatic feeding transmission mechanism comprises a first discharging device, a transmission bracket, a material selecting assembly, a transmission assembly with a conveying belt, a servo motor for driving the transmission belt assembly, a regulating and fixing device, a second discharging device and a recovery assembly, and the material selecting assembly, the regulating and fixing device, the servo motor and the recovery assembly are electrically connected with the numerical control system. The automatic laser engraving machine for conveying the product through the conveying belt is characterized in that after the product is conveyed to a preset station, the conveying belt is stopped, and laser engraving is performed again. However, in the actual production process, the front station of the laser engraving station is a feeding station, the feeding station and the laser engraving station generally share a conveying belt, and products conveyed by the laser engraving station and the feeding station are generally asynchronous, so that after the conveying belt is stopped, the feeding station cannot feed normally. If the conveyer belt is not shut down, the product stops on radium carving station, because the sculpture time is longer, causes the product bottom to be worn and torn by the conveyer belt easily. Accordingly, the prior art is still in need of improvement and development. Disclosure of Invention In view of the shortcomings of
