[0002] Laser machine is a general term for laser engraving machine, laser cutting machine and laser marking machine. Laser machine uses its high-temperature working principle to act on the surface of the material being processed. In the contemporary parts processing process, it is often used for surface processing operations of parts. It is one of the most widely used equipment in the contemporary parts processing field. In the process of using laser machine processing, since the products to be processed are transported on the conveyor belt, the products will jitter and deviate during the transportation process, resulting in poor processing effect.

[0035] In another embodiment of the present invention, Figure 1 As shown,

[0036] The infrared rangefinder 503 arranged on the mounting block 501 measures the distance between the laser emitting tube 500 and the object to be processed, so as to facilitate the rapid response of the laser emitting tube 500, so that it can quickly approach the object to be processed and start working, thus saving a lot of processing time. At the same time, the cooling fan 504 is used to blow air to cool the object being processed, thus avoiding deformation of the object due to excessive temperature.

[0037] Working principle and effect of this utility model:

[0038] When the object to be processed is transported to the workbench 100 through the conveyor belt, the telescopic push rod 201 is started to position the object to be processed at the center of the workbench 100, and then the drive motor 303 is started. Under the action of the drive motor 303, the movable pressure plate 301 moves downward, and the pressure sensor 302 is used to know the degree of compression of the object to prevent the object from jumping. At this time, the infrared rangefinder 503 is started. According to the information fed back by the infrared rangefinder 503, the second linear slide 401 is started to move the laser transmitting tube 500 to the specified position, and the cooling fan 504 and the laser transmitting tube 500 are started at the same time. The laser beam acts on the surface of the object to be processed through the laser transmitting tube 500, and at the same time, the first linear slide 400 and the third linear slide 402 are started according to the set pattern path to perform laser operation on the object. During the laser operation, the cooling fan 504 blows air on the object to prevent the object from being deformed due to excessive temperature. When the laser operation is completed, the second linear slide 401 is started to keep the laser emitting tube 500 away from the object, and the driving motor 303 is started at the same time to release the pressure on the object by the movable pressure plate 301, and the telescopic push rod 201 is started at the same time to retract the output end of the telescopic push rod 201, and the object leaves the workbench 100 along the conveyor belt. At this time, the processing is completed. The utility model can realize automatic calibration and positioning of the object to be processed on the conveyor belt through the cooperation of the mobile positioning component 200 and the automatic clamping component 300, and can also apply a certain pressure to the object on the conveyor belt through the automatic clamping component 300, so as to avoid the jumping of the object to be processed on the conveyor belt. Moreover, since the device has a simple structure, it is convenient to operate and maintain, and is more suitable for small processing workshops.

[0039] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
