[0054] See also Figure 1 and Figure 2 The embodiment of the utility model provides a tool changing device 100 , which includes a tool disc buffer mechanism 10 and a tool changing mechanism 12 .

[0055] The tool changing mechanism 12 includes a tool disc magazine 14 and a transfer mechanism. The transfer mechanism is disposed in the tool disc magazine 14 . The tool disc magazine 14 is used to place the tool disc 11 .

[0056] The cutter disc buffer mechanism 10 is used to obtain the first cutter disc 11 on the device to be tool-changed.

[0057] The fork ruler assembly 18 is used to obtain the cutter disc 11 on the cutter disc buffer mechanism 10 , and to transfer the cutter disc 11 to the cutter disc buffer mechanism 10 , so as to transfer the cutter disc 11 between the tool changing mechanism 12 and the cutter disc buffer mechanism 10 .

[0058] The above-mentioned tool changing device 100 has a tool disc magazine 14 for placing a tool disc 11, and a tool disc buffer mechanism 10 and a transfer mechanism for exchanging the tool disc 11 on the device to be tool changed with the tool disc 11 on the tool changing mechanism 12, thereby realizing the replacement of the old tool disc 11 with the new one. No human intervention is required in the whole process, which can improve the efficiency and accuracy of tool replacement.

[0059] Specifically, in order to improve the production utilization rate of equipment, processing equipment 200 such as drilling machines are developing towards automation and intelligence, among which the automatic circulation of the cutter head 11 is an important part of realizing the automation of the drilling machine.

[0060] In the related art, when replacing cutting tools on processing equipment, the mode of stopping the machine for manual replacement is adopted, which cannot meet the development needs of fully automated production workshops, and manual tool replacement is inefficient and has a high error rate.

[0061] Therefore, the embodiment of the utility model provides a tool changing device 100 , which includes a tool disc buffer mechanism 10 and a tool changing mechanism 12 .

[0062] The cutter disc buffer mechanism 10 is installed on the tool changing equipment, and the first cutter disc 11 is placed in a designated area on the working platform of the processing equipment 200. When the first cutter disc 11 needs to be replaced, the processing platform drives the first cutter disc 11 to move to the position of the cutter disc buffer mechanism 10, so that the cutter disc buffer mechanism 10 can obtain the first cutter disc 11.

[0063] The transfer mechanism transfers the cutter disc 11 between the cutter disc magazine 14 and the cutter disc buffer mechanism 10, wherein the transfer mechanism includes a fork ruler assembly 18, and the fork ruler assembly 18 is used to obtain the cutter disc 11 on the cutter disc buffer mechanism 10, and to transfer the cutter disc 11 to the cutter disc buffer mechanism 10, thereby enabling the cutter disc 11 to be replaced between the tool to be changed equipment and the tool changing device 100. No human intervention is required in the entire process, which can improve the efficiency and accuracy of tool replacement.

[0064] In the following description, Figure 1 The Z-axis direction is shown as the first direction, the Y-axis direction is shown as the second direction, and the X-axis direction is shown as the third direction.

[0065] In certain embodiments, the transport mechanism further includes a circulation component, which is used to obtain the cutter disc 11 on the fork scale assembly 18 and transfer the cutter disc 11 in the cutter disc magazine 14 to the fork scale assembly 18 .

[0066] In this way, the cutter disc 11 can be transferred between the cutter disc buffer mechanism 10 and the cutter disc magazine 14 through the transmission of the circulation assembly and the fork ruler assembly 18 .

[0067] Specifically, after the cutter disc buffer mechanism 10 acquires the first cutter disc 11, the tool change mechanism 12 moves to the corresponding position of the cutter disc buffer mechanism 10, so that the fork scale assembly 18 of the tool change mechanism 12 can acquire the first cutter disc 11. After the fork scale assembly 18 acquires the first cutter disc 11, the circulation assembly can transfer the first cutter disc 11 from the fork scale assembly 18 to the cutter disc bin 14. Then the cutter disc bin 14 transfers the second cutter disc 11 to the circulation assembly, and the circulation assembly transfers the second cutter disc 11 to the fork scale assembly 18, and the fork scale assembly 18 transfers the second cutter disc 11 to the cutter disc buffer mechanism 10, and the cutter disc buffer mechanism 10 drives the second cutter disc 11 to move back to the area on the processing platform where the cutter disc 11 is placed, thereby completing the replacement of the cutter disc 11.

[0068] When the processing equipment 200 needs to replace the cutter disc 11, it needs to stop working and wait for the cutter disc 11 to be replaced. When the cutter disc 11 is replaced by the tool changing device 100, the tool changing mechanism 12 can be moved to the corresponding position in time to work when the processing equipment 200 needs to change the cutter disc 11, without the need for manual duty and replacement of the cutter disc 11, thereby saving the time of waiting and replacing the cutter disc 11 of the processing equipment 200. At the same time, the cutter disc 11 is placed in the cutter disc bin 14, and after the positions of different types and old and new cutter discs 11 are preset, the tool changing mechanism 12 can accurately take out the cutter disc 11 that needs to be replaced, and the error probability is greatly reduced compared to manual work, thereby realizing the fully automatic circulation of the cutter disc 11 of the processing equipment 200.

[0069] In some embodiments, the cutter disc buffer mechanism 10 is used to move along a first direction to obtain a first cutter disc on the device to be changed, and to drive the first cutter disc away from the device to be changed along the first direction.

[0070] The fork ruler assembly 18 is used to move to below the cutter disc buffer mechanism 10 along the second direction when the cutter disc buffer mechanism 10 drives the first cutter disc along the first direction away from the tool-changing device.

[0071] The cutter disc buffer mechanism 10 is used to drive the first cutter disc to move along the first direction until the fork ruler assembly 18 acquires the first cutter disc when the cutter disc buffer mechanism 10 is moved below the cutter disc buffer mechanism 10 .

[0072] The fork ruler assembly 18 is used to transfer the first cutter disc to the circulation assembly along the second direction when the first cutter disc is acquired.

[0073] The circulation component is used to drive the first cutter disc to move along the first direction and / or the second direction when the first cutter disc is acquired, and to transfer the first cutter disc to the cutter disc bin 14 along the third direction.

[0074] In this way, the cutter disc 11 on the device to be replaced can be replaced and stored in the cutter disc bin 14 .

[0075] Specifically, the tool disc buffer mechanism 10 lifts the tool disc 11 that needs to be replaced to make it separate from the processing platform of the tool to be replaced. After the fork scale assembly 18 of the tool changing mechanism 12 moves to the corresponding position, the tool disc buffer mechanism 10 descends, driving the tool disc 11 to fall onto the first conveying assembly on the fork scale assembly 18. The first conveying device 40 drives the tool disc 11 to move in the second direction along the third direction. At this time, the first flow tray 42a moves along the first guide rail to align with the fork scale assembly 18, and the tool disc 11 moves from the second direction along the third direction. The fork ruler assembly 18 moves to the first flow tray 42a, and the first flow tray 42a then drives the cutter disc 11 to move along the first direction. After the first flow tray 42a and the second flow tray 42b are aligned, the cutter disc 11 can move along the second direction of the third direction to the second flow tray 42b. After the second flow tray 42b is aligned with a cutter disc rack 34, the cutter disc 11 moves along the third direction of the second direction to the cutter disc rack 34. At this time, the cutter disc 11 is replaced from the tool to be replaced equipment and retracted into the cutter disc bin 14.

[0076] In some embodiments, the circulation assembly is used to move in the first direction and / or the second direction to obtain the second cutter disc in the cutter disc magazine 14, drive the second cutter disc to move in the first direction and / or the second direction, and transmit the second cutter disc to the fork scale assembly 18 along the second direction.

[0077] The fork ruler assembly 18 is used to drive the second cutter disc to move above the cutter disc buffer mechanism 10 along the second direction when the second cutter disc is acquired.

[0078] The cutter disc buffer mechanism 10 is used to move along the first direction until the second cutter disc is acquired when the fork ruler assembly 18 moves to above the cutter disc buffer mechanism 10 .

[0079] The fork scale assembly 18 is used to move in a direction away from the cutter disc buffer mechanism 10 when the cutter disc buffer mechanism 10 acquires the second cutter disc.

[0080] The cutter disc buffer mechanism 10 is used to drive the second cutter disc along the first direction to approach the device to be changed tool when the second cutter disc is obtained, until the second cutter disc is placed on the device to be changed tool.

[0081] In this way, the second cutter disc in the cutter disc magazine 14 can be replaced on the device to be replaced.

[0082] Specifically, the cutter disc 11 on a cutter disc rack 34 in the cutter disc magazine 14 moves along the third direction to the second flow tray 42b. After the second flow tray 42b is aligned with the first flow tray 42a, the cutter disc 11 can move along the second direction to the first flow tray 42a. The first flow tray 42a drives the cutter disc 11 to move along the first direction and align with the fork ruler assembly 18, and moves from the first flow tray 42a to the fork ruler assembly 18 along the second direction. At this time, the lifting block 22 of the cutter disc buffer mechanism 10 rises, and the positioning member 24 is inserted into the positioning hole at the bottom of the cutter disc 11 to fix the cutter disc 11 on the lifting block 22. The tool changing mechanism 12 is removed, and the cutter disc buffer mechanism 10 drives the cutter disc 11 back to the working platform of the equipment to be changed, thereby completing the replacement of the cutter disc 11 in the cutter disc magazine 14 to the equipment to be changed.

[0083] In certain embodiments, the cutter disc buffer mechanism 10 includes a first drive device 20, a lifting block 22 and a positioning member 24. The first drive device 20 is connected to the lifting block 22, and the positioning member 24 is arranged on the lifting block 22. The lifting block 22 is used to support the cutter disc 11, and the positioning member 24 is used to limit the position of the cutter disc 11 on the lifting block 22. The first drive device 20 is used to drive the lifting block 22 to drive the cutter disc 11 to move along a first direction so that the cutter disc buffer mechanism 10 obtains the first cutter disc 11 on the tool to be changed equipment.

[0084] In this way, the cutter disc buffer mechanism 10 can position and fix the cutter disc 11 and drive the cutter disc 11 to move.

[0085] Specifically, the tool of the tool-changing device is placed on the processing platform, and when the cutter disc 11 needs to be replaced, the processing platform drives the cutter disc 11 to move to the installation position of the cutter disc buffer mechanism 10. At this time, the lifting block 22 is located below the cutter disc 11, and the lifting block 22 has a positioning member 24 on the side facing the cutter disc 11, and the cutter disc 11 has a positioning hole on the side facing the lifting block 22. The positioning member 24 and the positioning hole cooperate with each other, and when the first driving device 20 drives the lifting block 22 to move along the first direction, the cutter disc 11 can be limited to a fixed position on the lifting block 22.

[0086] like Figure 4 As shown, in some embodiments, the positioning member 24 is a tapered pin, and the tapered head faces the side of the cutter disc 11. In this way, when there is a certain error in the relative position of the lifting block 22 and the cutter disc 11, the tapered head of the tapered pin can adjust and calibrate the position of the cutter disc 11 during the process of extending into the positioning hole. Using a tapered pin as the positioning member 24 can reduce the position accuracy requirement between the cutter disc buffer mechanism 10 and the cutter disc 11.

[0087] In some embodiments, the transfer mechanism also includes a circulation component, the cutter disc magazine 14 includes a first bracket 32 ​​and a plurality of cutter disc racks 34, the fork scale assembly 18 and the circulation component are arranged on the first bracket 32, and the first bracket 32 ​​has a accommodating space 36 for accommodating the cutter disc rack 34, and the plurality of cutter disc racks 34 are arranged in the accommodating space 36 along a first direction.

[0088] In this way, the tool changing mechanism 12 can also be used as a large-capacity tool disc 11 storage mechanism, making the replacement and storage of the tool disc 11 more efficient.

[0089] Specifically, the cutter head frame 34 is used to place the cutter head 11. Figure 3 and Figure 5 As shown, the first bracket 32 ​​of the cutter disc magazine 14 has a accommodating space 36 for accommodating a cutter disc rack 34, and a plurality of cutter disc racks 34 are arranged in sequence along a first direction, and each cutter disc rack 34 can be used to store a cutter disc 11. The cutter disc magazine 14 has enough space to carry a large number of cutter discs 11, so that the tool changing mechanism 12 can continuously replace the cutter discs 11 of a plurality of devices to be tool changed, so that the tool changing mechanism 12 has a high tool changing efficiency.

[0090] At the same time, when changing the tool, the new and old tool discs 11 can be placed on different tool disc racks 34 according to the preset storage logic, or the tool disc 11 information can be entered when the tool disc 11 is placed in the tool disc rack 34. This ensures that the required tool disc 11 is accurately obtained during the tool disc 11 replacement process, and the error probability is low.

[0091] Furthermore, the tool changing mechanism 12 can be directly used as a storage mechanism for storing the cutter discs 11, and the old cutter discs 11 in the cutter disc bin 14 can be processed and new cutter discs 11 can be put in later. In this way, the management efficiency of the cutter discs 11 can be improved.

[0092] See also Figure 5 In some embodiments, the cutter disc holder 34 includes a second bracket 38 and a first conveying device 40. The first conveying device 40 is disposed on the second bracket 38. The first conveying device 40 includes a second driving device and a first conveying assembly. The second driving device is used to drive the first conveying assembly along a third direction to drive the cutter disc 11 to enter or exit the second bracket 38.

[0093] In this way, the cutter disc holder 34 can receive the cutter disc 11 on the circulation assembly and transfer the cutter disc 11 to the circulation assembly.

[0094] Specifically, the second bracket 38 is used to store the cutter disc 11, and the first conveying component is arranged on the second bracket 38. For example, the first conveying component may include a conveyor belt 72 arranged on the second bracket 38, and the conveying direction of the conveyor belt is a third direction. The second driving device drives the conveyor belt 72 to work, and can drive the cutter disc 11 to move in the third direction, so that the cutter disc 11 in the cutter disc frame 34 is transmitted to the circulation component, or the cutter disc 11 on the circulation component enters the cutter disc frame 34.

[0095] See also Figure 3 , Figure 5 and Figure 6 In some embodiments, the flow assembly includes a moving assembly and a flow tray 42, the moving assembly includes a second driving device and a slide rail, the slide rail is set on the first bracket 32, the flow tray 42 is movably set on the slide rail, the second driving device is installed on the flow tray 42, and the second driving device is used to drive the flow tray 42 to move on the slide rail.

[0096] In this way, the second driving device drives the circulation tray 42 to move on the slide rail, so that the circulation tray 42 transfers the cutter disc 11 between the cutter disc bin 14 and the fork ruler.

[0097] Specifically, the slide rail is set on the first bracket 32 ​​of the cutter disc magazine 14, and the flow tray 42 is movably set on the slide rail. The second driving device drives the flow tray 42 to move on the slide rail, so that it can reach various positions of the cutter disc magazine 14 to transport the cutter disc 11.

[0098] The position of the slide rail can be arranged according to the cutter disc bin 14. In the illustrated embodiment, the cutter disc bin 14 includes a first cutter disc bin 14a and a second cutter disc bin 14b. The first cutter disc bin 14a and the second cutter disc bin 14b are spaced apart along the second direction.

[0099] The first cutter head magazine 14a has a first accommodating space 36a and a second accommodating space 36a arranged in parallel along the second direction, and the second cutter head magazine 14b has a third accommodating space 36c and a fourth accommodating space 36d arranged in parallel along the second direction. A plurality of cutter head racks 34 are arranged in each accommodating space 36 along the first direction.

[0100] The moving assembly includes a first moving assembly and a second moving assembly. The first moving assembly includes a first slide rail 46a, and the second moving assembly includes a second slide rail 46b. The first slide rail 46a and the second slide rail 46b are respectively arranged between the first tool disc bin 14a and the second tool disc bin 14b, and the flow tray 42 is arranged between the first slide rail 46a and the second slide rail 46b.

[0101] The flow tray 42 includes a first flow tray 42a and a second flow tray 42b. The first flow tray 42a is slidably disposed on a first slide rail 46a, and the second flow tray 42b is slidably disposed on a second slide rail 46b. In this way, the first flow tray 42a moves along the first direction on the first slide rail 46a, and can receive and obtain the cutter disc 11 on the cutter disc holder 34 of the first accommodating space 36a and the third accommodating space 36c. The second flow tray 42b moves along the first direction on the second slide rail 46b, and can receive and obtain the cutter disc 11 on the cutter disc holder 34 of the second accommodating space 36b and the fourth accommodating space 36d, so that the flow tray 42 can reach the cutter disc holder 34 at any position in the cutter disc bin 14 to transfer the cutter disc 11.

[0102] In other embodiments, the moving component can be used to drive the flow tray 42 to move in the first direction and the second direction, that is, the slide rails are arranged on the first bracket 32 ​​along the first direction and the second direction, thereby achieving that a flow tray 42 can move on the slide rails along the first direction and the second direction to reach the cutter disc rack 34 at any position in the cutter disc bin 14 to transfer the cutter disc 11.

[0103] See also Figures 7 to 10 In some embodiments, the flow tray 42 includes a supporting plate 48, a second conveying device and a third conveying device. The supporting plate 48 is arranged on a slide rail, and the second conveying device and the third conveying device are arranged on the supporting plate 48.

[0104] The second conveying device includes a second conveying assembly 50 and a third driving device 52. The third driving device 52 is used to drive the second conveying assembly 50 to drive the cutter disc 11 to move along the third direction, so as to transfer the cutter disc 11 to the cutter disc frame 34 along the third direction.

[0105] The third conveying device includes a third conveying assembly 54 and a fourth driving device 56. The fourth driving device 56 is used to drive the third conveying device to drive the cutter disc 11 to move along the second direction, so as to transfer the cutter disc 11 to the fork scale assembly 18 along the second direction.

[0106] In this way, the circulation tray 42 can move the cutter disc 11 in two directions, thereby transferring the cutter disc 11 between the cutter disc magazine 14 and the fork ruler assembly 18 .

[0107] Specifically, when the flow tray 42 is used to transport the cutter disc 11, the cutter disc 11 moves between the cutter disc frame 34 and the flow tray 42 along the third direction, and moves between the flow tray 42 and the fork ruler assembly 18 along the second direction.

[0108] In the illustrated embodiment, the fork ruler assembly 18 is disposed between the first cutter disc bin 14a and the second cutter disc bin 14b and is located on the top of the first bracket 32. The first flow tray 42a is used to transfer the cutter disc 11 between the fork ruler assembly 18, the cutter disc rack 34 in the first accommodating space 36a and the third accommodating space 36c and the second flow tray 42b. The second flow tray 42b can be used to transfer the cutter disc 11 between the cutter disc rack 34 in the second accommodating space 36b and the fourth accommodating space 36d and the first flow tray 42a.

[0109] The fork ruler assembly 18 is arranged at the top of the first bracket 32, and the projections of the second transfer tray and the fork ruler assembly 18 in the first direction overlap, so the second flow tray 42b cannot rise to the top of the first bracket 32. Therefore, the second flow tray 42b needs to cooperate with the first flow tray 42a to realize the taking and storage of the cutter disc 11 in the second accommodating space 36b and the fourth accommodating space 36d. Taking the storage of the cutter disc 11 as an example, when the cutter disc 11 needs to be stored in the second accommodating space 36b and the fourth accommodating space 36d, the fork ruler assembly 18 first obtains the cutter disc 11 of the cutter disc buffer mechanism 10, and the first flow tray 42a rises to the top of the first bracket 32 ​​and docks with the fork ruler assembly 18. The fork ruler assembly 18 transfers the cutter disc 11 to the first flow tray 42a along the second direction, the first flow tray 42a moves along the first direction to the docking position with the second flow tray 42b, and transfers the cutter disc 11 to the second flow tray 42b along the second direction, and then the second flow tray 42b transfers the cutter disc 11 to the cutter disc rack 34 of the second accommodating space 36b or the fourth accommodating space 36d along the third direction, thereby completing the storage of the cutter disc 11.

[0110] In some embodiments, the third driving device 52 and the fourth driving device 56 are servo motors, the second conveying assembly 50 and the third conveying assembly 54 are conveyor belts 72, and the servo motors can provide power to the conveyor belts 72 so that the conveyor belts 72 drive the cutter disc 11 to move.

[0111] In some embodiments, the second conveying component 50 and the third conveying component 54 respectively include two conveyor belts 72 and a synchronization shaft 58. The two conveyor belts 72 of the second conveying component 50 are respectively arranged on the support plate 48 along the third direction, and the two conveyor belts 72 of the third conveying component 54 are respectively arranged on the support plate 48 along the second direction. The synchronization shaft 58 is respectively connected to the two conveyor belts 72 that are driven in the same direction, so as to synchronize the transmission of the two conveyor belts 72, thereby allowing the cutter disc 11 to move smoothly on the flow tray 42.

[0112] See also Figures 7 to 10In some embodiments, a receiving groove 60 is opened on the supporting plate 48, and the third conveying component 54 is arranged in the receiving groove 60. The third conveying component 54 also includes a lifting drive device 60, which is connected to the third conveying component 54 and is used to drive the third conveying component 54 to extend and retract along the first direction.

[0113] In this way, the third transmission assembly 54 can be prevented from interfering with the movement of the cutter disc 11 along the third direction on the support plate 48 .

[0114] Specifically, the movement of the cutter disc 11 on the flow tray 42 includes moving along the third direction to move from the flow tray 42 to the cutter disc frame 34, and moving along the second direction to move between the first flow tray 42a and the second flow tray 42b, and moving from the flow tray 42 to the fork ruler assembly 18.

[0115] When the cutter disc 11 moves along the third direction on the flow tray 42, if the third conveying assembly 54 protrudes relative to the support tray, it will interfere with the movement of the cutter disc 11. Therefore, a receiving groove 60 is opened on the support plate 48 of the flow tray 42, and the third conveying assembly 54 is placed in the receiving groove 60. The third conveying assembly 54 is driven to extend out of the receiving groove 60 or retract into the receiving groove 60 by the lifting drive device 60. When the third conveying assembly 54 is retracted in the receiving groove 60, the second conveying assembly 50 will not interfere with the support tray when driving the cutter disc 11 to move. When the third conveying assembly 54 extends from the receiving groove 60, the lifting drive device 60 can drive the third conveying assembly 54 to rise, so that the cutter disc 11 only contacts the third conveying assembly 54 and moves on the flow tray 42 with the third conveying assembly 54, so that the cutter disc 11 can move in two directions on the flow tray 42.

[0116] In some embodiments, the flow tray 42 includes a synchronous gear 64 and a universal joint coupling 66. The two sides of the synchronous gear 64 are connected to the third transmission assembly through two universal joint couplings 66 respectively. The synchronous gear 64 is connected to the fourth drive device 56 and is used to convert the kinetic energy provided by the fourth drive device 56 into a vertically distributed, synchronously rotating dual-axis power. The universal joint coupling 66 is used to transfer the kinetic energy provided by the fourth drive device 56 to the third transmission assembly, so that the kinetic energy provided by the fourth drive device 56 can be transferred to the third transmission assembly 54 when the third transmission assembly 54 is in a raised state.

[0117] In some embodiments, the lifting drive device 60 includes a cylinder 68 and a transmission rod 70, and the third conveying assembly 54 includes a conveyor belt 72 and a base plate 74, and the conveyor belt 72 is arranged on the base plate 74. A transmission groove 76 and a guide lifting groove 78 are provided on the base plate 74, and the third conveying device includes a guide block 80, which is fixed on the support plate 48 and partially extends into the lifting guide groove, and the length direction of the lifting guide groove has a certain angle with the second direction, and the transmission rod 70 is connected to the cylinder 68 and partially inserted into the transmission groove 76, and the length direction of the transmission groove 76 is parallel to the first direction. The working power of the cylinder 68 is sequentially transmitted to the transmission rod 70 and the transmission groove 76, the guide lifting groove 78 and the guide block 80 along the second direction. Since the guide block 80 is fixed on the support plate 48, the part of the guide block 80 inserted into the guide lifting groove 78 pushes the groove wall of the guide lifting groove 78 to drive the base plate 74 and the conveyor belt 72 to rise or fall along the second direction.

[0118] See also Figures 7 to 10 In some embodiments, the flow tray 42 includes a first guide device 82 and a second guide device 84, and the first guide device 82 and the second guide device 84 are arranged on the support plate 48. The first guide device 82 is used to guide and limit the cutter disc 11 in a third direction, and the second guide device 84 is connected to the lifting drive device 60. The lifting drive device 60 is used to control the second guide device 84 to extend or retract relative to the support plate 48. When the second guide device 84 is extended, the second guide device 84 is used to guide and limit the cutter disc 11 along the second direction.

[0119] In this way, the first guide device 82 and the second guide device 84 guide and limit the movement of the cutter disc 11 on the cutter disc frame 34 and the circulation tray 42, so that the cutter disc 11 moves to a relatively fixed position among the cutter disc frame 34, the circulation tray 42 and the fork ruler assembly 18, thereby reducing the difficulty of positioning when the tool changing mechanism 12 and the cutter disc buffer mechanism 10 exchange the cutter disc 11.

[0120] Specifically, the cutter disc 11 can move along the third direction and the second direction on the circulation tray 42, and guide devices in two directions are respectively provided on the circulation tray 42, so that the position of the cutter disc 11 when moving to the cutter disc frame 34, the circulation tray 42 and the fork ruler assembly 18 is relatively fixed, thereby reducing the difficulty of positioning when the tool changing mechanism 12 and the cutter disc buffer mechanism 10 exchange the cutter disc 11.

[0121] In the illustrated embodiment, the circulation tray 42 moves on the first bracket 32 ​​via a moving component. When the circulation tray 42 moves to align with a certain cutter disc rack 34 in the cutter disc bin 14, the first conveying component and the second conveying component 50 on the circulation tray 42 work together to move the cutter disc 11 in the cutter disc rack 34 to the circulation tray 42. During this process, the first guide device 82 can guide and limit the moving cutter disc 11 along the third direction.

[0122] The circulation tray 42 includes two second guide devices 84 respectively arranged along the two sides of the support plate 48 close to the cutter disc chamber 14. The second guide devices 84 can extend or retract along the first direction relative to the surface of the support plate 48 on which the cutter disc 11 is placed. When the cutter disc 11 moves from the cutter disc frame 34 to the circulation tray 42, the first guide device 82 guides the cutter disc 11 along the third direction, and the second guide device 84 close to the side of the cutter disc 11 shrinks to avoid interfering with the movement of the cutter disc 11 along the third direction. At the same time, the second guide device 84 away from the side of the cutter disc 11 extends, and stops moving when the cutter disc 11 moves to abut the second guide device 84, so that the position of the cutter disc 11 on the second guide device 84 can be limited.

[0123] It should be noted that the second guide device 84 and the third conveying assembly 54 can share a lifting drive device 60, or the second guide device 84 and the third conveying assembly 54 can each use a lifting drive device 60.

[0124] See also Fig.11 In some embodiments, the fork ruler assembly 18 includes a third bracket 86 and a fourth conveying device 88, the fourth conveying device 88 includes a fourth conveying assembly and a fifth driving device, the fifth driving device is connected to the fourth conveying assembly, and the fifth driving device is used to drive the fourth conveying assembly to drive the cutter disc 11 to move along the second direction.

[0125] In this way, the fork ruler assembly 18 can transfer the cutter disc 11 between the cutter disc buffer mechanism 10 and the flow tray 42 .

[0126] Specifically, the cutter disc 11 on the fork ruler assembly 18 is driven by the fourth transmission device to move along the second direction, thereby realizing the transfer of the cutter disc 11 between the cutter disc buffer mechanism 10 and the circulation tray 42 .

[0127] See also Fig.11 In some embodiments, the third bracket 86 includes a guide portion 90 and a mounting portion 92, the mounting portion 92 is used to set the fourth conveying device 88, and the guide portion 90 is used to guide and limit the cutter disc 11 along the first direction.

[0128] In this way, when the fork scale assembly 18 acquires the cutter disc 11, the guide portion 90 guides the cutter disc 11 to fall into the position of the fourth transmission assembly, thereby reducing the accuracy requirement of the cutter disc 11 when it is transferred between the fork scale assembly 18 and the buffer structure of the cutter disc 11.

[0129] Specifically, when the tool changing mechanism 12 obtains the tool disc 11 on the tool disc buffer mechanism 10, it cooperates with the positioning member 24 on the tool disc buffer mechanism 10, and the tool disc 11 is first positioned by the positioning member 24 on the tool disc buffer mechanism 10. When docking, the fork scale assembly 18 is located below the tool disc 11, and the tool disc buffer mechanism 10 moves downward, so that the tool disc 11 falls onto the fork scale assembly 18. At this time, the guide part 90 on the fork scale assembly 18 guides the tool disc 11 in the first direction. As a result, the accuracy requirements in the first and third directions when the fork scale is docked are weakened, ensuring that the tool changing mechanism 12 and the tool disc 11 on the tool disc buffer mechanism 10 are stable and efficient in their placement and pick-up actions.

[0130] At the same time, when the cutter disc 11 moves along the second direction on the fork scale assembly 18 , the guide portion 90 guides and limits the cutter disc 11 along the second direction, so that the cutter disc 11 is stably transported to the circulation tray 42 .

[0131] See also Fig.11 In some embodiments, the fork scale assembly 18 includes a first adjustment mechanism 94 and a second adjustment mechanism 96, which are disposed on the third bracket 86, the first adjustment mechanism 94 being used to adjust the position of the third bracket 86 in the first direction, and the second adjustment mechanism 96 being used to adjust the position of the third bracket 86 in the second direction.

[0132] In this way, the cutter disc buffer mechanism 10 and the fork ruler assembly 18 can be accurately aligned so as to accurately transfer the cutter disc 11 .

[0133] Specifically, the sensing device 28 on the tool changing mechanism 12 detects the distance between the tool changing mechanism 12 and the device to be tool changed. The position of the tool disc buffer mechanism 10 on the device to be tool changed is fixed. After the sensing device 28 obtains the distance between the tool changing mechanism 12 and the device to be tool changed in the third direction, the distance between the fork scale assembly 18 and the tool disc buffer mechanism 10 in the third direction can be adjusted through the second adjustment mechanism 96 on the fork scale assembly 18 to compensate for the distance between the fork scale assembly 18 and the tool disc buffer mechanism 10 in the third direction.

[0134] An identification point is set on the tool changing device, and the moving chassis 26 of the tool changing mechanism 12 can identify the distance difference between the current fork scale assembly 18 and the tool disc buffer mechanism 10 in the first direction and the second direction through the identification point, and the tool disc bin 14 and the fork scale assembly 18 thereon are driven to move in the third direction by the carrier platform 30 on the moving chassis 26, so as to compensate for the error in the third direction between the fork scale assembly 18 and the tool disc buffer mechanism 10. The first adjustment mechanism 94 on the fork scale assembly 18 can move the fork scale assembly 18 in the first direction, so as to compensate for the error in the first direction between the fork scale assembly 18 and the tool disc buffer mechanism 10.

[0135] Optionally, in one embodiment, the identification point is a QR code on the tool changing device, and the tool changing mechanism 12 obtains the distance difference between the current fork scale assembly 18 and the tool disc buffer mechanism 10 in the first direction and the second direction by reading the QR code.

[0136] See also Figures 1 to 3 In some embodiments, the tool changing mechanism 12 includes a mobile chassis 26, and the tool disc magazine 14 is set on the mobile chassis 26. The mobile chassis 26 is used to drive the tool disc magazine 14 to move. The mobile chassis 26 includes a sensing device 28, and the sensing device 28 is used to adjust the relative position of the tool disc magazine 14 and the tool to be changed according to the detection signal so that the fork ruler assembly 18 can obtain the first tool disc 11 on the tool disc buffer mechanism 10.

[0137] In this way, the movable chassis 26 can drive the fork scale assembly 18 to move so that the fork scale assembly 18 can obtain the first cutter disc 11 on the cutter disc buffer mechanism 10 .

[0138] Specifically, the mobile chassis 26 adjusts the posture of the tool changing mechanism 12 according to the detection signal obtained by the sensing device 28, that is, keeps the mobile chassis 26 parallel to the surface opposite to the tool changing device, so that the fork ruler assembly 18 can first reach a reference position when acquiring the tool disc 11 on the tool disc buffer mechanism 10, so as to ensure the accuracy of subsequent position adjustment.

[0139] The mobile chassis 26 may include an AGV (Automated Guided Vehicle). The AGV has a visual system and a control system, and can cooperate with the sensing device 28 to drive the tool disc magazine 14 to move, so that the tool changing mechanism 12 and the tool disc buffer mechanism 10 are aligned.

[0140] At the same time, the sensing device 28 is used to obtain the distance between the tool changing mechanism 12 and the cutter disc buffer mechanism 10 in the second direction, so that the movable chassis 26 can adjust the distance between the fork scale assembly 18 and the cutter disc buffer mechanism 10 in the second direction.

[0141] In some embodiments, the sensing device 28 includes two laser displacement sensors, which are arranged on a side of the mobile chassis 26 facing the tool-changing device. The laser displacement sensor can detect the distance between the tool-changing mechanism 12 and the tool-changing device. The detection signal obtained by the laser displacement sensor can be used to correct the posture of the tool-changing mechanism 12 and provide a data basis for the distance of the fork ruler assembly 18 in the second direction, thereby ensuring the docking accuracy of the fork ruler assembly 18 with the tool disc buffer mechanism 10 in the second direction.

[0142] In some embodiments, the mobile chassis 26 includes a carrier platform 30 that can move along a third direction. The carrier platform 30 is disposed on the mobile chassis, and the cutter head magazine 14 is disposed on the carrier platform 30 .
