[0027] See also Figures 1-4 The utility model provides an eight-head precision engraving machine, comprising a base 1, a material rack mechanism 2, a processing mechanism 3, a transport mechanism 4, and a positioning mechanism 5. The material rack mechanism 2, the processing mechanism 3, the transport mechanism 4, and the positioning mechanism 5 are all arranged on the base 1, and the processing mechanism 3 is arranged above the positioning mechanism 5. The transport mechanism 4 is used to transport the workpiece on the material rack mechanism 2 to the positioning mechanism 5. The processing mechanism 3 is used to process the workpiece on the positioning mechanism 5. The positioning mechanism 5 is provided with eight limit plates 51 for fixing the workpiece. The processing mechanism 3 is provided with eight grinding assemblies, each of which is corresponding to one of the limit plates 51.

[0028] Furthermore, the grinding assembly includes a drive motor 31 and a grinding head 32. The processing mechanism 3 is provided with a support platform 33 and eight connecting blocks 34. The eight connecting blocks 34 are all arranged on the support platform 33. Each of the drive motors 31 is installed on the side wall of a connecting block 34.

Suction cups for securing the workpieces are provided on both the front and back sides of the workpiece holders 432. The suction cups provided on both the front and back sides of the workpiece holders 432 enable the manipulator 43 to transport eight workpieces at a time. First, the manipulator 43 places the four workpieces on the front side onto the four limit plates 51 on the left side, then moves the manipulator 43 laterally and rotates the workpiece holders 432 180°, so that the four workpieces on the back side are placed on the four limit plates 51 on the right side. This increases the number of workpieces that can be processed at the same time, thereby improving processing efficiency.

[0033] Furthermore, the eight limiting plates 51 are divided into two workpiece fixing assemblies, each of which has four limiting plates 51, and each workpiece fixing assembly corresponds to four workpiece holders 432. The robot 43 first places the four workpieces on the front side onto one workpiece fixing assembly, then moves the robot 43 laterally and rotates the workpiece holders 432 180°, placing the four workpieces on the back side onto the other workpiece fixing assembly. This increases the number of workpieces that can be processed simultaneously, improving processing efficiency.

[0034] Furthermore, the positioning mechanism 5 is provided with two screw slides 52, and each workpiece fixing assembly is slidably mounted on one of the screw slides 52. Each screw slide 52 can drive a workpiece fixing assembly to move forward and backward, so that the limit plate 51 can correspond to the workpiece holder 432, thereby realizing the picking and placing of the workpiece.
