Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this invention. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0040] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0041] In this embodiment:

[0042] Reference Figure 1-2 The diagram shows a preferred embodiment of the present invention.

[0043] The feed device for drill bit processing in this embodiment includes a processing chamber 1. A processing table 2 is provided inside the processing chamber 1. A lifting seat 22 is installed on the processing table 2. A drill bit loading and unloading head 23 is installed inside the lifting seat 22. A tooling fixing table 21 is also provided at the bottom of the drill bit loading and unloading head 23 on the processing table 2. A material tray 11 is also installed in front of the drill bit loading and unloading head 23 in the processing chamber 1 via a bracket. A guide rail 3 is installed on the material tray 11, and a number of drill bits 31 are conveyed through the guide rail 3. A loading robot 4 and a vision positioning probe 32 are also installed on the material tray 11. The vision positioning probe 32 is placed in front of the loading robot 4 and is used to position the drill bits 31 to be loaded and unloaded. The loading robot 4 is used to load and unload the drill bits 31 from the guide rail 3 to the drill bit loading and unloading head 23.

[0044] The drill bit 31 has a drill shank 311 at its bottom and a support ring 312 on the outside of the drill shank 311.

[0045] See attached document Figure 3-5 As shown, a guide motor 33 is installed at the bottom of the material tray 11, and several guide wheels 34 are also installed on the material tray 11 via a rotating shaft. The guide rail 3 is installed outside the guide wheels 34 and is driven by the guide motor 33. Several insertion slots 35 are evenly distributed on the upper part of the guide rail 3. The drill bit shank 311 is inserted and fixed through the insertion slots 35. Under the drive of the guide motor 33, the guide wheels 34 can drive the external guide rail 3 to achieve transmission. The guide rail 3 uses the insertion slots 35 to insert and transport the drill bit 31 with the drill bit shank 311, so that different drill bits 31 can be loaded and unloaded by the loading robot 4 according to processing requirements.

[0046] Furthermore, the loading robot 4 includes a base 41 and a sliding telescopic mechanism 42. A slide table 43 is slidably mounted on the top of the base 41. The slide table 43 is connected to the telescopic part of the sliding telescopic mechanism 42. Driven by the telescopic part of the sliding telescopic mechanism 42, the slide table 43 can slide on the base 41, which allows the loading robot 4 to move between the processing table 2 and the guide rail 3, facilitating the loading and unloading of the drill bit 31.

[0047] Furthermore, two sets of lifting telescopic mechanisms 443 are installed on the top of the base 41. The telescopic part of the lifting telescopic mechanism 443 is equipped with a lifting platform 44. Guide rods 444 are also installed around the top of the base 41. The lifting platform 44 has guide holes. The lifting platform 44 slides outside the guide rods 444 through the guide holes. Under the action of the telescopic part of the lifting telescopic mechanism 443, the lifting platform 44 can adjust the lifting height of the loading robot 4 so that the drill bit 31 can be inserted and fixed or lifted and pulled out from the insertion port 35 of the guide rail 3.

[0048] It is worth noting that two sets of mounting brackets 461 are fixed to the bottom of the lifting platform 44. A reversing telescopic mechanism 46 is connected between the ends of the two mounting brackets 461 via a rotating shaft. A robotic arm 47 is connected to the telescopic part of the reversing telescopic mechanism 46 via a rotating shaft. Guide plates 441 are provided on both sides of the top of the lifting platform 44. Arc-shaped guide grooves 442 are formed on the guide plates 441. Guide blocks 471 that slide within the guide grooves 442 are provided on both sides of the robotic arm 47. The top of the platform 41 is also provided with a biasing platform 45. The end of the biasing platform 45 is equipped with a deflecting telescopic mechanism 451. The telescopic part of the deflecting telescopic mechanism 451 passes through and extends into the interior of the biasing platform 45, and a deflecting block 452 is installed thereon. The bottom of the reversing telescopic mechanism 46 is provided with a push block 462. The top of the deflecting block 452 is provided with a groove. The push block 462 is placed inside the groove. The direction of the robotic arm 47 is adjusted by the extension and retraction of the telescopic part of the reversing telescopic mechanism 46 in conjunction with the extension and retraction of the deflecting telescopic mechanism 451.

[0049] Specifically, in the appendix Figure 5 In the process of retracting the telescopic part of the reversing telescopic mechanism 46, the end of the robotic arm 47 connected to the rotating shaft of its telescopic part will be pulled downward, causing the guide block 471 to slide to the center in the guide groove 442 of the guide plate 441. At this time, the robotic arm 47 will be in an upright state. Then, by pushing the push block 462 horizontally through the telescopic mechanism 451, the push block 462 at the end of the reversing telescopic mechanism 46 will be pushed to the left to push the guide block 471, causing the telescopic part of the reversing telescopic mechanism 46 to shift to the right. At this time, by pushing out the telescopic part of the reversing telescopic mechanism 46, the robotic arm 47 can be flipped to the left, completing the reversing operation of the robotic arm 47.

[0050] Similarly, when the robotic arm 47 needs to flip to the right, the above operation is reversed.

[0051] The robotic arm 47 is internally equipped with a clamping telescopic mechanism 473. A push-pull plate 472 is installed on the telescopic part of the clamping telescopic mechanism 473. Clamping plates 474 are connected to both sides of the push-pull plate 472 via rotating shafts. Gear grooves 475 are provided on both sides of the robotic arm 47. Gears 476 that mesh with the gear grooves 475 are provided on the outer side of the rotating shaft connection of the clamping plate 474. Limit blocks 445 are also provided on both sides of the top of the lifting platform 44. The limit blocks 445 are used to support the robotic arm 47 and... Keeping the robotic arm 47 horizontal, during the extension and retraction of the push-pull plate 472 via the telescopic part of the clamping telescopic mechanism 473, the gear 476 at the end of the clamping plate 474 is driven to rotate by the meshing tooth grooves 475 on both sides of the robotic arm 47. This allows the two clamping plates 474 to maintain a clamping state when the push-pull plate 472 is pushed to its farthest point by the telescopic part of the clamping telescopic mechanism 473. When the push-pull plate 472 retracts through the telescopic part of the clamping telescopic mechanism 473, the clamping plates 474 can continue to open in order to complete the clamping and retraction operation of the drill bit 31.

[0052] It is worth noting that the clamping plate 474 is arranged in a double layer, and the layers are positioned above and below the support ring 312 of the drill bit shank 311. This ensures that when the clamping plate 474 is clamped on the outside of the support ring 312, the position of the clamping plate 474 clamping the drill bit shank 311 remains unchanged no matter how the robotic arm 47 flips left or right, which facilitates positioning.

[0053] This solution installs the material tray 11 above the processing table 2, which can effectively prevent dust and debris generated during processing from contaminating the feeding robot 4 and the material tray 11. The guide rail 3 on the material tray 11 is driven by a motor to transport the drill bit 31 and is positioned in conjunction with the vision positioning probe 32, which can automatically switch the required drill bit 31.

[0054] The loading robot 4 can move flexibly and adjust its height between the processing table 2 and the guide rail 3. The robot arm 47 can flip left and right to transfer the drill bit 31 between the processing table 2 and the guide rail 3. It is equipped with a clamping telescopic mechanism 473 to clamp and position the drill bit 31, ensuring that the clamping position remains unchanged and improving processing efficiency and accuracy.

[0055] In this embodiment, all electrical components are automatically controlled through programming with an S4-400 PLC, and each component can be assembled using standard parts, eliminating the need for additional customized production, thus reducing equipment costs and effectively improving the efficiency and quality of drill bit processing.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
