[0050] By setting up the tool storage logistics system 1, the storage location 2 and the tool retrieval and matching machine 3, the tool storage logistics system 1 can take out the full box / incomplete box of tool discs from the storage location 2 and send it to the tool retrieval and matching machine 3 for tool matching. After the tool matching is completed, the full box / incomplete box of tool discs with complete drill cutters can be taken out from the tool retrieval and matching machine 3, and the incomplete box of tool discs can be returned to the storage location 2 again. The full box / incomplete box of tool discs can be directly shipped out, realizing automatic storage and automatic matching of drill cutters, replacing manual operation, reducing labor costs, and improving production efficiency.

[0051] See also Figure 2-Figure 4 . Figure 2 It is a structural diagram of the preferred structure of the knife storage logistics system. Figure 3 yes Figure 2 A partial enlarged view of point I in the middle. Figure 4 yes Figure 2 A partial enlarged view of point II in the middle.

[0052] In the first aspect, the knife storage logistics system 1 includes an empty box feeding line 11 for feeding empty knife disk boxes, an outbound line 12 for outputting full or incomplete knife disk boxes in the storage location 2, a direct outbound line 13 for directly outputting knife disk boxes after being equipped with knives or directly outputting knife disk boxes in the storage location 2, and a return line 14 for transporting incomplete knife disk boxes back to the storage location 2. A plurality of knife picking and matching machines 3 are arranged along the empty box feeding line 11; the outbound line 12 is arranged parallel to and adjacent to the direct outbound line 13 and the return line 14, and the outbound line 12, the direct outbound line 13 and the return line 14 are also arranged along the plurality of knife picking and matching machines 3, and the storage location 2 is arranged on one side of the outbound line 12, the direct outbound line 13 and the return line 14.

[0053] The knife storage logistics system 1 of this embodiment is divided into two groups and is symmetrically arranged, and each group of the knife storage logistics system 1 has two empty box feeding lines 11 and two outbound lines 12. In this embodiment, a total of 12 knife picking and matching machines 3 are arranged, and the empty box feeding line 11, the outbound line 12, the direct outbound line 13 and the return line 14 of each group of the knife storage logistics system 1 pass through 6 of the knife picking and matching machines 3.

[0054] The two groups of knife storage logistics systems further include an empty box return line 15 for returning the empty boxes on the empty box feeding line 11, and the empty box return line 15 is arranged parallel to and adjacent to the empty box feeding line 11. In addition, an empty box NG cache line 151 for caching the knife disc boxes whose code scanning is NG on the empty box feeding line 11 is arranged at the end of the empty box return line 15.

[0055] One group of the knife storage logistics systems 1 also includes a full box / partial box feeding line 16 for loading full boxes or partial boxes of knife disc boxes and transferring them to the storage location 2, and the full box / partial box feeding line 16 is arranged on one side of the end of the return line 14.

[0056] The end of the return line 14 is provided with a return NG line 141 for caching the knife disk boxes on the return line 14 or the full box / partial box feeding line 16. The return NG line 141 is used to cache the non-full box knife disk boxes that have been scanned NG on the return line 14, and finally taken away manually; it can also be used to cache the full box or partly full box knife disk boxes that have been scanned NG on the full box / partial box feeding line 16 in the following embodiment 2, and finally taken away manually.

[0057] The full box / partial box feeding line 16 is used for manually feeding full boxes or partial boxes of tool discs containing drill bits. After being fed, the tool disc boxes can be scanned first, and then the module robot grabs the tool disc boxes with correct scanning and puts them on the RGV robot. Finally, the RGV robot transports them to the storage location 2 for storage. The tool disc boxes with NG scanning are grabbed onto the return NG line 141 and then taken away manually.

[0058] The empty box feeding line 11 is used for manually feeding empty boxes. After the empty boxes are fed, they continue to flow to the knife picking and matching machine 3. After scanning the code, they are placed on the empty box return line 15 for the knife picking and matching machine 3 to configure drill tools. The tool disc box that fails to pass the code scan is grabbed onto the empty box NG cache line 151 and finally taken away manually.

[0059] A module robot can be used to grab a full box or an incomplete box of knife disc boxes from the RGV robot and move it to the outbound delivery line 12, and then continue after scanning the code. Since the outbound delivery line 12 runs through the six knife picking and matching machines 3, it is ensured that each knife picking and matching machine 3 can pick up a full box or an incomplete box of knife disc boxes from two of the outbound delivery lines 12.

[0060] The ends of the two outbound lines 12 are provided with an outbound NG line 121 for caching the cutter disc boxes that have been scanned NG on the outbound line 12. The outbound NG line 121 is used to cache the full or partial cutter disc boxes that have been scanned NG on the outbound line 12, and finally take them away manually.

[0061] The end of the direct outbound line 13 is also provided with a direct outbound NG cache line for caching the full or incomplete knife disk boxes whose code scanning is NG on the direct outbound line 13 .

[0062] The direct outbound delivery line 13 is connected to the knife picking and matching machine 3 and the storage location 2. The whole box of knife discs after the knife picking and matching machine 3 has finished matching the knives is placed on the direct outbound delivery line 13, and is transported out by the direct outbound delivery line 13 after scanning the code. The knife disc boxes that failed the code scanning are grabbed onto the direct outbound delivery NG buffer line, and finally taken away manually. Each direct outbound delivery line 13 is composed of two sections, that is, one section supplies three knife picking and matching machines 3, to ensure that the knife picking and matching machine 3 will not stop directly outbound due to a failure in one of the knife picking and matching machines, causing the entire knife matching system to stop outbound delivery. The knife disc boxes transferred from the storage location 2 can be placed on the direct outbound delivery line 13 and directly outbound through the direct outbound delivery line 13.

[0063] The knife picking and matching machine 3 places the unnecessary incomplete knife disc boxes on the return line 14. After scanning the code, the incomplete knife disc boxes are transported back to the storage location 2 by the return line 14. The incomplete knife disc boxes that fail the code scanning are grabbed onto the return NG line 141 and finally taken away manually.

[0064] Preferably, the empty box feeding line 11, the outgoing line 12, the direct outgoing line 13 and the return line 14 all include a plurality of segments connected end to end.

[0065] For example, each of the outbound lines 12 of this embodiment is composed of two sections, that is, one section supplies three knife picking and matching machines 3. Each knife picking and matching machine 3 can pick up materials from two of the outbound lines 12, ensuring that the knife picking and matching machine 3 will not cause the entire knife matching system to stop matching due to a failure in one of the knife picking and matching machines.

[0066] Preferably, transition rollers 110 are provided at the end connections of the adjacent segments of the empty box feeding line 11, the outgoing line 12, the direct outgoing line 13 and the return line 14. The transition rollers 110 can ensure that the cutter box passes smoothly through the docking interfaces between the segments.

[0067] Furthermore, the outbound line 12 , the direct outbound line 13 and the return line 14 share a plurality of brackets, and the plurality of brackets are arranged along the bottom of the outbound line 12 , the direct outbound line 13 and the return line 14 .

[0068] Preferably, a CCD detector 17 and a code scanning mechanism 18 are arranged above the outgoing line 12, the direct outgoing line 13 and the return line 14. The CCD detector 17 can image the tool tray box to determine whether the drill bits in the tool tray box are fully assembled, and can also identify the color, direction, position and number of the drill bits in the tool tray box, and can identify whether there are foreign objects in the tool tray hole of the tool tray box, and can also perform QR code detection. The code scanning mechanism 18 can use a code scanner commonly used in production lines in the prior art.

[0069] A through-beam photoelectric sensor 19 is provided along the return line 14. The through-beam photoelectric sensor 19 is used to detect whether the cutter head box is in place.

[0070] It should be noted that the multiple sections of the empty box feeding line 11, the outgoing line 12, the direct outgoing line 13, and the return line 14, as well as the empty box return line 15 all include a conveying motor and a conveyor belt, and the output end of the conveying motor is connected to the conveyor belt in a transmission manner. The conveying motor drives the conveyor belt to rotate, thereby realizing the conveyance of the cutter disc box. In addition, the empty box feeding line 11, the outgoing line 12, the direct outgoing line 13, and the multiple sections of the return line 14, as well as the empty box return line 15 are also equipped with a tensioning mechanism commonly used in the prior art for tensioning the conveyor belt, and a blocking mechanism driven by a motor or a cylinder, the blocking mechanism is arranged on one side of the above-mentioned conveyor belt, and is used to block the cutter disc box. These structures are simple and easy to implement for technicians in this field.

[0071] The conveying motor can preferably be a speed-regulating motor.

[0072] The knife storage logistics system 1 can take out a full box / incomplete box of knife discs from the storage location 2 and send it to the knife retrieval and matching machine 3 for knife matching. After the knife matching is completed, the full box / incomplete box of knife discs with complete drill cutters can be taken out from the knife retrieval and matching machine 3, and the incomplete box of knife discs can be returned to the storage location 2 again. The full box / incomplete box of knife discs can be directly shipped out, realizing automatic storage and automatic matching of drill cutters, replacing manual operation, reducing labor costs, and improving production efficiency.
