Then, the slider is controlled by an electric slide rail to reach the top of the suction pipe. The output end of the second slide cylinder moves downward, driving the material taking pipe to move downward. When the material taking pipe contacts the diamond, the vacuum pump starts to work and draws a vacuum, so that the taking pipe can be taken out. The material tube adsorbs the diamond, and then under the control of the electric slide rail, the diamond is installed on the diamond holder, and finally the lifting cylinder is raised to push the lifting sleeve, the lifting sleeve rises and supports the diamond holder, and then the punching cylinder works downward, driving the punching head to squeeze the buckle ears of the diamond holder downward, so that the buckle ears are bent inward to buckle the diamond, so that the diamond is firmly assembled on the diamond holder.
