[0020] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] In this embodiment: Reference Figure 1-2 As shown, a preferred embodiment of the present invention is provided.

[0022] The feeding device for drill bit processing of the present embodiment comprises a processing warehouse 1, wherein a processing table 2 is arranged inside the processing warehouse 1, a lifting seat 22 is installed on the processing table 2, a drill bit loading and unloading machine head 23 is installed inside the lifting seat 22, the processing table 2 is located at the bottom of the drill bit loading and unloading machine head 23 and is also provided with a tool fixing table 21, the processing warehouse 1 is located in front of the drill bit loading and unloading machine head 23 and is also installed with a material tray 11 through a bracket, a material guide rail 3 is installed on the material tray 11, and a plurality of drill bits 31 are transported through the material guide rail 3, a feeding manipulator 4 and a visual positioning probe 32 are also installed on the material tray 11, the visual positioning probe 32 is placed in front of the feeding manipulator 4, and is used to locate the drill bit 31 to be loaded and unloaded, and the feeding manipulator 4 is used to load and unload the drill bit 31 from the material guide rail 3 to the drill bit loading and unloading machine head 23; A drill shank 311 is disposed at the bottom of the drill bit 31 , and a support ring 312 is disposed outside the drill shank 311 .

[0023] See attached Figure 3-5 As shown, a material guide motor 33 is installed at the bottom of the material tray 11, and a plurality of guide wheels 34 are installed on the material tray 11 through a rotating shaft. The material guide rail 3 is installed on the outside of the guide wheel 34, and the material guide rail 3 is driven by the material guide motor 33. A plurality of sockets 35 are evenly distributed on the upper part of the material guide rail 3, and the drill shank 311 is plugged and fixed through the sockets 35. Under the drive of the material guide motor 33, the guide wheel 34 can drive the external material guide rail 3 to realize transmission, and the material guide rail 3 uses the sockets 35 to plug and transport the drill bit 31 with the drill shank 311, so that different drill bits 31 can be loaded and unloaded by the loading robot 4 according to processing requirements.

[0024] Furthermore, the feeding manipulator 4 includes a base 41 and a sliding telescopic machine 42. A slide 43 is slidably mounted on the top of the base 41. The slide 43 is connected to the telescopic part of the sliding telescopic machine 42. Driven by the telescopic part of the sliding telescopic machine 42, the slide 43 can slide on the base 41, so that the feeding manipulator 4 can move between the processing table 2 and the guide rail 3, which is convenient for loading and unloading the drill bit 31. In addition, two sets of lifting and telescopic machines 443 are installed on the top of the base 41, and a lifting platform 44 is installed on the telescopic part of the lifting and telescopic machines 443. Guide rods 444 are also installed around the top of the base 41. Guide holes are opened on the lifting platform 44, and the lifting platform 44 slides outside the guide rods 444 through the guide holes. Under the action of the telescopic part of the lifting and telescopic machines 443, the lifting platform 44 can adjust the lifting height of the feeding manipulator 4, so that the drill bit 31 can be inserted and fixed or lifted and pulled out from the socket 35 of the guide rail 3; It is worth noting that two groups of mounting brackets 461 are fixed to the bottom of the lifting platform 44, and a reversing telescopic machine 46 is connected between the ends of the two mounting brackets 461 through a rotating shaft, and the telescopic part of the reversing telescopic machine 46 is connected to a mechanical arm 47 through a rotating shaft. Guide plates 441 are provided on both sides of the top of the lifting platform 44, and arc-shaped guide grooves 442 are provided on the guide plates 441. Guide blocks 471 sliding inside the guide grooves 442 are provided on both sides of the mechanical arm 47. A deflection platform 45 is also provided on the top of the platform 41, and a diverting telescopic machine 451 is installed at the end of the deflection platform 45. The telescopic part of the diverting telescopic machine 451 penetrates and extends to the inside of the deflection platform 45, and is installed with a diverting block 452; a push block 462 is provided at the bottom of the reversing telescopic machine 46, and a groove is provided on the top of the diverting block 452. The push block 462 is placed inside the groove. The direction of the mechanical arm 47 is adjusted by the reversing telescopic machine 46 cooperating with the telescopic part of the diverting telescopic machine 451 to adjust the direction of the mechanical arm 47; Specifically, in the attached Figure 5 In the process of the telescopic part of the reversing telescopic machine 46 contracting, the end of the mechanical arm 47 connected to the rotating shaft of the telescopic part will be pulled downward, causing the guide block 471 to slide to the middle in the guide groove 442 of the guide plate 441. At this time, the mechanical arm 47 will be in an upright state, and then the push block 462 will be pushed to move horizontally by the telescopic machine 451. The push block 462 at the end of the reversing telescopic machine 46 is moved to the left to move the guide block 471 so that the telescopic part of the reversing telescopic machine 46 is shifted to the right. At this time, the telescopic part of the reversing telescopic machine 46 is pushed out to make the mechanical arm 47 flip to the left, completing the reversing operation of the mechanical arm 47. Similarly, when the robot arm 47 needs to flip to the right, the above operation is reversed.

[0025] A clamping and placing telescopic machine 473 is installed inside the mechanical arm 47, and a push-pull plate 472 is installed on the telescopic part of the clamping and placing telescopic machine 473. Clamps 474 are connected to the push-pull plate 472 on both sides through a rotating shaft. Tooth grooves 475 are opened on both sides of the mechanical arm 47. The clamps 474 are located on the outside of the rotating shaft connection part of the push-pull plate 472 and are provided with gears 476 meshing with the tooth grooves 475. Limit blocks 445 are also provided on both sides of the top of the lifting platform 44. The limit blocks 445 are used to lift the mechanical arm 47 and The mechanical arm 47 is kept in a horizontal setting. During the process of pushing the push-pull plate 472 to extend and retract through the telescopic part of the clamping and telescoping machine 473, the gear 476 at the end of the clamping plate 474 will be driven to rotate through the tooth grooves 475 meshing on both sides of the mechanical arm 47. This enables the two clamping plates 474 to maintain a clamped state when the push-pull plate 472 is pushed to the farthest point through the telescopic part of the clamping and telescoping machine 473. When the push-pull plate 472 is contracted through the telescopic part of the clamping and telescoping machine 473, the clamping plate 474 can continue to open so as to complete the clamping and placing operation of the drill bit 31.

[0026] It is worth noting that the splint 474 is double-layered, and the plate layers are placed between the upper and lower parts of the support ring 312 of the drill shank 311. This ensures that when the splint 474 is clamped on the outside of the support ring 312, no matter how the robotic arm 47 flips left or right, the position of the splint 474 clamping the drill shank 311 remains unchanged, which facilitates positioning.

[0027] In this solution, the material tray 11 is installed above the processing table 2, which can effectively prevent the dust and debris generated during the processing from polluting the loading robot 4 and the material tray 11. The guide rail 3 on the material tray 11 is driven by a motor to realize the conveyance of the drill bit 31, and cooperates with the visual positioning probe 32 for positioning, and can automatically switch the drill bit 31 required for loading; The loading robot 4 can flexibly move and adjust the height between the processing table 2 and the guide rail 3, and the robot arm 47 can be flipped left and right to transfer the drill bit 31 between the processing table 2 and the guide rail 3, and is equipped with a clamping telescopic machine 473 for clamping and positioning the drill bit 31 to ensure that the clamping position remains unchanged, thereby improving processing efficiency and accuracy.

[0028] In this embodiment, each electrical component is automatically controlled through PLC programming of model S4-400, and each component can be assembled through standard parts without the need for additional customized production, which reduces equipment costs and effectively improves the efficiency of drill bit processing and product quality.
