Abstract

A visual laser engraving machine includes a bottom plate, clamping assemblies and a product body. A portal frame is disposed around a surface of the bottom plate. An electrically controlled pulley is slidably connected with a horizontal slide rail at an inner side thereof. A laser device is slidably connected between longitudinal slide rails. A lower slide rail is arranged at a middle of the surface of the bottom plate. The clamping assemblies are slidably connected with the lower slide rail at an inner side of the lower slide rail and each includes a control pulley, electric push rods, a servo motor and miniature push rods. The product body is placed between the miniature push rods.

Claims (15)

1 . A visual laser engraving machine, comprising:

a bottom plate, clamping assemblies and a product body, wherein a portal frame is disposed around a surface of the bottom plate, and a horizontal slide rail is arranged on an inner side of a top of the portal frame;

an electrically controlled pulley is slidably connected with the horizontal slide rail at an inner side of the horizontal slide rail, and longitudinal slide rails are fixed on a bottom of the electrically controlled pulley;

a laser device is slidably connected between the longitudinal slide rails, and an infrared distance meter is arranged on an outer side surface of the laser device;

a lower slide rail is arranged at a middle of the surface of the bottom plate;

the clamping assemblies are slidably connected with the lower slide rail at an inner side of the lower slide rail and are configured for adjusting a height of a surface to be engraved of a product;

each of the clamping assemblies comprises a control pulley, electric push rods, a servo motor and miniature push rods, wherein the electric push rods are fixed on a surface of the control pulley, the servo motor is fixed on tops of the electric push rods, and the miniature push rods are arranged on upper and lower sides of an end of the servo motor; and

the product body is placed between the miniature push rods.

2 . The visual laser engraving machine according to claim 1 ,

wherein the laser device and the infrared distance meter are arranged perpendicular to the bottom plate, and the bottom plate is arranged parallel to all of the horizontal slide rail, the longitudinal slide rails and the servo motors.

3 . The visual laser engraving machine according to claim 1 , wherein the miniature push rods are symmetrically distributed about a horizontal central axis of the servo motor, and there are totally four miniature push rods provided.

4 . The visual laser engraving machine according to claim 1 , wherein the product body is rotatably connected to the servo motors through the miniature push rods, and the servo motors are symmetrically distributed about a vertical central axis of the bottom plate.

5 . The visual laser engraving machine according to claim 1 , wherein the infrared distance meter and the laser device are slidably connected to the longitudinal slide rails and the horizontal slide rail through the electrically controlled pulley, and the infrared distance meter is in clamping connection with the laser device.

6 . The visual laser engraving machine according to claim 1 , wherein a first fan is arranged on an upper surface of the top of the portal frame, and the top of the portal frame is of a mesh-shaped structure.

7 . The visual laser engraving machine according to claim 1 , wherein an activated carbon plate is inserted into the bottom plate, and a second fan is arranged at a bottom of the bottom plate.
