[0059] like Figure 1 As shown, the diamond material distribution device includes a material holding structure, a material suction structure, a material suction structure driving mechanism and a material moving structure;

[0060] The material suction structure driving mechanism includes a first frame 614, a first guide rail 615 fixedly mounted on the first frame 614, a support platform 616 slidably mounted on the first guide rail 615, and a first linear driving mechanism 618 mounted on the first frame 614 and used to drive the support platform 616 to slide on the first guide rail 615; the material transfer structure is mounted on the support platform 616;

[0061] The material suction structure is installed on the material transfer structure. When the first linear drive mechanism 618 drives the material transfer structure to slide on the first guide rail 615 to the first position, the material suction structure is connected with the material holding structure below the first position, and then the diamond particles in the material holding structure are sucked by vacuuming.

[0062] The material suction structure is also used to be driven by the material transfer structure to extend into the mold cavity 641 below the second position when the first linear drive mechanism 618 drives the material transfer structure to slide on the first guide rail 615 to the second position, and then the aforementioned diamond particles are arranged in the mold cavity 641 by breaking the vacuum.

[0063] The above technical solution is a basic solution, and the diamond feeding device realizes the automation of the suction structure for sucking and discharging diamond particles by adopting the drive of the first linear driving mechanism, combined with the cooperation of the material holding structure and the material moving structure. It can be understood that the mold cavity 641 is opened on a mold 640.

[0064] Furthermore, in this embodiment, a first through cavity (not shown in the figure) is opened in the middle of the support platform 616; the material transfer structure includes a first base plate 630, a first cylinder 625 and a second cylinder 628; the first base plate 630 is installed on the top of the support platform 616 and covers the top opening of the first through cavity; the material suction structure includes a top cover 637 and a movable plate 631;

[0065] The first substrate 630 is provided with a first through hole and a second through hole respectively; the first cylinder 625 comprises a first cylinder body 623 directly or indirectly mounted on the first substrate 630 and a first piston rod 624 slidably penetrated in the first through hole and passed through the first substrate 630 through the first through hole, extended into the first through cavity and fixedly connected to the top cover 637, and telescopically mounted on the first cylinder body 623; a ventilation cavity 638 is provided at the bottom of the top cover 637; a vacuum hole 639 is provided at the top of the top cover 637, which is communicated with the ventilation cavity 638 and is used to be connected to a vacuum device (not shown in the figure);

[0066] The second cylinder 628 includes a second cylinder body 627 directly or indirectly mounted on the first base plate 630 and a second piston rod 626 slidably inserted into the second through hole and passing through the first base plate 630 through the second through hole, extending into the first through cavity and fixedly connected to the movable plate 631, and telescopically mounted on the second cylinder body 627;

[0067] A second through cavity is formed in the middle of the movable plate 631, and a top cover 637 is detachably mounted on the top of the movable plate 631 to partially or completely cover the second through cavity;

[0068] The material suction structure further includes a first connecting plate 633, a second connecting plate 636, and a plurality of needle tubes 634 detachably provided on the first connecting plate 633; ​​the plurality of needle tubes 634 are arranged in an array;

[0069] The second connecting plate 636 is provided with a plurality of communicating holes 644 arranged in an array; the communicating holes 644 correspond one to one with the needle tubes 634;

[0070] The second connecting plate 636 is covered on the first connecting plate 633 to fix the plurality of needle tubes 634 therebetween and to connect the needle tubes 634 with the corresponding communication holes 644;

[0074] Here, the needle tube 634 and the pipeline 643 can slide relative to each other by the driving of the first cylinder 625 and the second cylinder 628. Specifically, when the top cover 637 is lifted relative to the movable plate 631, the needle tube 634 retracts in the pipeline 643 (such as Figure 5 As shown in FIG. 6 ), a receiving groove for accommodating diamond particles is formed at the bottom of the pipeline 643, and the ventilation cavity 638 is evacuated to achieve the adsorption of diamond particles. When the top cover 637 is in close contact with the movable plate 631, the needle tube 634 passes through the bottom of the pipeline 643 (as shown in FIG. 6 ). Figure 6As shown in FIG. 6 ), the diamond particles can be pushed into the metal powder layer. Since the plurality of pipelines 643 are arranged in an array, the diamond particles can be evenly distributed. In addition, during the diamond particle distribution process, the diamond particles are pushed into the metal powder layer through the needle tube 634, which reduces the airflow generated during the diamond particle distribution process and can improve the quality of the finished diamond saw blade.

[0075] Furthermore, in this embodiment, the material transfer structure further includes a fixed plate 621, and the first cylinder body 623 and the second cylinder body 627 are both fixedly mounted on the fixed plate 621;

[0076] The material transfer structure further includes a plurality of columns 620 respectively connected between the fixing plate 621 and the first substrate 630 .

[0080] Here, by adopting the stabilizing plate 629, when the first piston rod 624 is raised or lowered, the suspended top cover 637 can be raised or lowered more smoothly.

[0089] Here, the third cylinder 612 can be used to lift the material tank 613, thereby achieving docking between the material storage structure and the material suction structure. When the adsorption block 635 extends into the material tank 613, the material tank 613 forms a closed space, and the diamond particles in the material tank 613 can be adsorbed in the bottom opening of the pipeline 643 by evacuating the ventilation cavity 638.
