Description

Technical Field

[0001] This invention relates to the field of PCB drilling technology, and more particularly to an automatic tool changer system and processing equipment. Background Technology

[0002] With the approaching Industry 5.0, the level of automation in manufacturing has changed dramatically. The PCB (printed circuit board) drilling process is also moving towards full automation. However, some consumables on drilling machines still require manual, periodic replacement, including the drilling tools. In practical applications, the inventors discovered that PCB processing on CNC drilling machines requires different sizes and quantities of tools to meet production needs. However, the tool magazine capacity of the drilling machine is limited. Once the tools in the magazine reach the end of their service life, manual or robotic arms are needed to replenish or replace the tools and tool heads.

[0003] In existing technologies, some manufacturers use manual methods to replace the cutterhead, which involves numerous repetitive operations and is time-consuming. Furthermore, during cutterhead replacement, the drilling rig needs to be shut down for safety reasons, further wasting production capacity and impacting overall production efficiency. Some manufacturers use automated tool changers such as robotic arms, but these devices have relatively long movement trajectories and are time-consuming. Especially when operating multiple spindles on multiple drilling rigs, the equipment costs are high and the overall efficiency is low, hindering their widespread adoption in actual production. Summary of the Invention

[0004] In view of this, this application provides an automatic tool changer system and processing equipment to solve the problems of low automation, low efficiency and high cost in the existing drilling rig tool changer operation.

[0005] This application provides an automatic cutter head changing system, including a mobile feeding device, a cutter head fixing device mounted on a drilling machine, and a cutter head transfer device. The cutter head fixing device includes a base plate, a first positioning component mounted on the base plate, and a first fixing component for fixing the cutter head. The cutter head transfer device includes a support frame, a slide table, and a cutter head loading and unloading component. The support frame has a loading and unloading section adjacent to the first positioning component. A loading section and a unloading section are respectively provided on both sides of the loading and unloading section. The slide table is slidably mounted on the support frame along the line connecting the loading section and the unloading section. The cutter head loading and unloading component drives the cutter head to move between the slide table and the first positioning component. The mobile feeding device includes a moving trolley, a cutter head transfer component, and a feeding component for placing the cutter head. The moving trolley moves the outlet end of the feeding component to the side of the loading section or the unloading section, so that the cutter head transfer component can transfer the cutter head to the cutter head transfer device or remove the cutter head from the cutter head transfer device.

[0006] In the above scheme, the cutterhead fixing device and the cutterhead transfer device are installed on the drilling machine. The configured mobile feeding device can transport the cutterhead on it to the cutterhead transfer device, and then the cutterhead transfer device places the cutterhead on the cutterhead fixing device. After the drilling machine has replaced the drill bit on the cutterhead, the cutterhead transfer device removes the cutterhead from the cutterhead fixing device and transfers it to the mobile feeding device. Therefore, the automatic cutterhead changing system has high overall efficiency and low equipment cost when changing cutterheads on multiple spindles of the drilling machine, and can solve the problems of low automation, low efficiency and high cost in the existing technology of drilling machine cutterhead changing operation.

[0007] In one possible design, the first positioning component includes a positioning block disposed on the base plate, the positioning block being used to abut against the outer surface of the cutter head.

[0008] In the above scheme, a positioning block is provided on the base plate. When the cutter head is transferred from the cutter head transfer device to the cutter head fixing device, the cutter head can be positioned quickly and accurately by the positioning block, thus ensuring the positional accuracy of the cutter head.

[0009] In one possible design, the first fixing component includes an electromagnet disposed on the side of the positioning block, and the side of the cutter disc is provided with a suction part that can be attracted by the electromagnet.

[0010] In the above scheme, the cutter head is provided with a suction part that can attract the electromagnet. After the cutter head is positioned, the electromagnet located on the side of the positioning block will attract and fix the cutter head, preventing the cutter head from shaking or shifting during the cutter change process, thus improving the success rate and stability of the drilling rig when changing cutters.

[0011] In one possible design, the first fixing component further includes a sensing mechanism, and the cutter head is provided with an identification part that can be identified by the sensing mechanism.

[0012] In the above scheme, after the cutter head is transferred to the predetermined position on the cutter head fixing device, the identification part on the cutter head is identified by the sensing mechanism, the cutter head fixing device is activated and the cutter head is fixed, thus improving the automation level and stability of the automatic cutter head changing system.

[0013] In one possible design, the cutter head transfer device further includes a transfer drive unit connected to the slide table, the transfer drive unit being used to drive the slide table to move on the support frame.

[0014] In the above scheme, the transfer drive can drive the slide to move back and forth on the support frame, which improves the automation level of the automatic tool changer system, optimizes the trajectory of the tool changer to move the tool head, and thus improves the system efficiency and saves costs.

[0015] In one possible design, the cutter head loading and unloading assembly is connected to the support frame and is disposed above the loading and unloading part. The cutter head loading and unloading assembly includes a loading and unloading drive and an adsorption member for picking up the cutter head. The adsorption member is disposed at the output end of the loading and unloading drive. The loading and unloading drive is used to drive the adsorption member to drive the cutter head to reciprocate between the positioning assembly and the loading and unloading part.

[0016] In the above scheme, the cutter head loading and unloading assembly can efficiently load and unload the cutter head, improving the automation level of the automatic cutter head changing system, and thus improving the utilization rate of the automatic cutter head changing system.

[0017] In one possible design, the feeding assembly includes a feeding frame and at least one support plate, the support plate being disposed on the feeding frame, and a transmission belt mechanism being wound around the support plate, the transmission belt mechanism being capable of driving the cutter head to move along the length direction of the support plate.

[0018] In the above scheme, the position of the cutter head placed on the support plate is moved by the transmission belt mechanism, which improves the efficiency of cutter head loading and unloading.

[0019] In one possible design, the feeding assembly includes multiple support plates, each of which is slidably mounted on the feeding frame in a vertical direction. The moving vehicle is equipped with a lifting component, which is used to push the support plates up and down.

[0020] In the above scheme, the storage capacity of the cutter head of the feeding component is increased by setting multiple support plates, and the support plate is switched by pushing the lifting component to move the support plate, which further improves the feeding efficiency and the adaptability of the automatic cutter head changing system.

[0021] In one possible design, the feeding frame is provided with a guide rod arranged in a vertical direction, and the bearing plate is provided with a guide structure, which is sleeved on the guide rod.

[0022] In the above scheme, the movement accuracy of the bearing plate is improved by utilizing the cooperation between the guide structure and the guide rod.

[0023] In one possible design, the automatic tool changer system further includes a chuck cleaning assembly, a pressure foot replacement assembly, and a runout measuring instrument, all of which are mounted on the base plate.

[0024] In the above solution, the automation level and tool changing accuracy of the automatic tool changer system are improved by using a cleaning chuck assembly, a pressure foot replacement assembly, and a runout measuring instrument.

[0025] This application also provides a processing device that includes the automatic tool changer system described in any of the above claims. Therefore, the processing device naturally possesses the advantages of the aforementioned automatic tool changer system. Furthermore, based on the characteristics of the automatic tool changer system, the automation level of the processing device is further improved, thereby enhancing the construction of a smart factory.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0074] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0075] The following describes a specific embodiment of the automatic tool changer system provided in this application, based on its structure.

[0076] When PCBs (printed circuit boards) are processed on CNC drilling machines, different sizes and quantities of cutting tools are required to meet production needs. However, the tool magazine capacity of the drilling machine 10 is limited. After the tools in the tool magazine reach the end of their service life, they need to be replenished or replaced manually or by a robotic arm. For example, a new tool can be placed in the tool turret, which is then placed on the drilling machine 10. After the tools in the tool magazine of the drilling machine 10 are used up, the drilling machine 10 places the old tool in the tool turret and removes the new tool from the tool turret, thus achieving tool replacement.

[0077] In the existing technology, some manufacturers use manual replacement of the cutterhead 20. This method not only involves numerous repetitive operations and is time-consuming, but also requires the drilling rig 10 to be stopped for safety during cutterhead replacement, further wasting production capacity and affecting overall production efficiency. Some manufacturers also use automated tool changing devices such as robotic arms to replace the cutterhead 20. However, the overall movement trajectory of robotic arms and existing automated tool changing devices is relatively long, taking a considerable amount of time. When multiple drilling rigs 10 are set up in the factory, and each drilling rig 10 has multiple spindles, the existing tool changing devices require a separate automated tool changing device for each spindle of each drilling rig 10. Therefore, configuring robotic arms is not only costly but also inefficient, making it unsuitable for widespread use in actual production. To solve the above technical problems, the inventive concept of this application was developed, which will be specifically described through the following embodiments.

[0078] Please see Figures 1 to 5This application provides an automatic cutter head changing system 100, which includes a mobile feeding device 3, a cutter head fixing device 1 mounted on a drilling machine, and a cutter head transfer device 2. The cutter head fixing device 1 includes a base plate 11, a first positioning component 12 mounted on the base plate 11, and a first fixing component 13 for fixing the cutter head. The cutter head transfer device 2 includes a support frame 21, a slide table 22, and a cutter head loading and unloading component 23. The support frame 21 is provided with a loading and unloading part 211 adjacent to the first positioning component 12. The loading and unloading part 211 has a loading part 212 and a unloading part 213 on both sides. The slide table 22 is slidably disposed on the support frame 21 along the line connecting the loading section 212 and the unloading section 213. The cutter head loading and unloading assembly 23 is used to drive the cutter head to move between the slide table 22 and the first positioning assembly 12. The mobile feeding device 3 includes a moving carriage 31, a cutter head transfer assembly 32 and a feeding assembly 33 for placing the cutter head. The moving carriage 31 is used to drive the outlet end of the feeding assembly 33 to move to the side of the loading section 212 or the unloading section 213 so that the cutter head transfer assembly 32 can transfer the cutter head to the cutter head transfer device 2 or remove the cutter head from the cutter head transfer device 2.

[0079] Please see Figure 1 Both the cutter head fixing device 1 and the cutter head transferring device 2 are mounted on the drilling machine. In some embodiments, both the cutter head fixing device 1 and the cutter head transferring device 2 are located at the end of the drilling machine to avoid affecting the range of motion of the drilling machine. The number of cutter head fixing devices 1 and cutter head transferring devices 2 matches the number of spindles on the drilling machine, while the number of movable feeding devices 3 can be set to one or more. Because the movable feeding devices 3 can move freely between each drilling machine 10, their number can be flexibly set according to the speed at which each drilling machine 10 consumes tools and the production cycle.

[0080] Please see Figure 2 and Figure 3 The cutter head fixing device 1 includes a base plate 11, a first positioning component 12 disposed on the base plate 11, and a first fixing component 13 for fixing the cutter head. The cutter head on the base plate 11 houses a drill bit for replacement by the drilling machine. The base plate 11 can be fixed on the drilling machine 10 at any convenient position for the spindle to clamp the tool. The first positioning component 12 is disposed on the base plate 11 and may include multiple positioning blocks 121 arranged according to the shape of the cutter head to facilitate cutter head positioning. The first fixing component 13 can be a common clamping device with jaws or a suction device with a suction cup. After the cutter head is positioned, the first fixing component 13 can fix the cutter head to prevent it from shifting during tool changes.

[0081] Please see Figure 2 and Figure 3The cutter head transfer device 2 includes a support frame 21 disposed next to the cutter head fixing device 1, a slide table 22 slidably disposed on the support frame 21, and a cutter head loading and unloading assembly 23. The support frame 21 is provided with a loading and unloading part 211 adjacent to the first positioning assembly 12. The loading and unloading part 211 is correspondingly disposed to the opening of the first positioning assembly 12. The loading and unloading part 211 is provided with a feeding part 212 and a discharging part 213 on both sides respectively. The support frame 21 can be provided with a slide rail or other structure so that the slide table 22 can be slidably disposed on the support frame 21 along the line connecting the feeding part 212 and the discharging part 213. At least one cutter head placement position can be provided on the slide table 22. In this way, after the cutter head moves to the cutter head placement position on the slide table 22, the slide table 22 can drive the cutter head to move between the feeding part 212, the loading and unloading part 211, and the discharging part 213, so that the cutter head can be transferred between the slide table 22, the cutter head fixing device 1, and the mobile feeding device 3.

[0082] Please see Figure 4 The cutter head 20 may be provided with multiple holes for placing cutters. The side of the cutter head 20 may be provided with a suction part 201 and an identification part 202. In some embodiments, suction parts 201 are provided on both opposite sides of the cutter head 20. The position of the identification part 202 may be, but is not limited to, the side of the cutter head 20.

[0083] In some embodiments, two tool holder positions may also be provided on the slide table 22. In this case, the slide table 22 has at least two states during reciprocating motion. Please refer to [link / reference]. Figure 2 and Figure 3 ,in:

[0084] The first state is as follows: the two cutter heads of the slide table 22 are positioned to correspond to the loading section 212 and the unloading section 211, respectively. At this time, the cutter head can be moved from the moving feeding device 3 to the cutter head position corresponding to the loading section 212. At the same time, the cutter head can be moved from the base plate 11 of the cutter head fixing device 1 to the cutter head position corresponding to the unloading section 211.

[0085] The second state is as follows: the two cutter heads of the slide table 22 are positioned to correspond to the loading and unloading section 211 and the unloading section 213 respectively. At this time, the cutter head can be moved from the cutter head position corresponding to the unloading section 213 to the mobile feeding device 3. At the same time, the cutter head can be moved from the cutter head position corresponding to the loading and unloading section 211 to the base plate 11 of the cutter head fixing device 1.

[0086] Through the reciprocating motion of the slide 22, in conjunction with the actions of the cutter head loading and unloading assembly 23 and the cutter head transfer assembly 32, the cutter head loaded with new cutters is transferred from the mobile feeding device 3 to the base plate 11 of the cutter head fixing device 1 and abuts against the first positioning assembly 12. It can also transfer the cutter head loaded with old cutters from the cutter head fixing device 1 to the mobile feeding device 3.

[0087] Please see Figure 5 The mobile feeding device 3 includes a mobile cart 31 that can move freely between the cutterhead supply point and each drilling rig 10, a cutterhead transfer assembly 32, and a feeding assembly 33 for placing the cutterheads. The mobile cart 31 can be an AGV (Automated Guided Vehicle) with a tracking function, which can accurately move to a predetermined position. Multiple cutterheads can be placed inside the feeding assembly 33, which has an outlet end for the cutterheads to enter and exit. The mobile cart 31 can drive the outlet end of the feeding assembly 33 to the side of the loading section 212 or unloading section 213, so that the cutterhead transfer assembly 32 can transfer the cutterheads to the cutterhead transfer device 2 or remove the cutterheads from the cutterhead transfer device 2. The cutterhead transfer assembly 32 can be a suction cup or mechanical gripper, etc., capable of transferring objects. Specifically, in one embodiment, the cutterhead transfer assembly 32 for picking up or releasing materials can be a suction cup or mechanical gripper. It should be noted that the suction cup can utilize a vacuum environment provided by a compressor, generating negative pressure at the suction section 201 to pick up materials, and positive pressure at the suction section 201 to release materials. The mechanical gripper can be a motor-controlled gripper that moves a linkage mechanism via a transmission assembly. To avoid damaging the material, this mechanical gripper can clamp or release the material from two opposing planes. It is understandable that when using a suction cup, the risk of material damage is lower, making it easier to ensure material quality. In practical applications, those skilled in the art can choose to use either a suction cup or a mechanical gripper based on actual product requirements.

[0088] The mobile feeding device 3 can transport the cutter head loaded with new cutters to the cutter head transfer device 2, and then the cutter head transfer device 2 places the cutter head on the cutter head fixing device 1. After the drill bit on the cutter head is replaced by the drilling machine, the cutter head can be taken out from the cutter head fixing device 1 and transferred to the mobile feeding device 3 by the cutter head transfer device 2.

[0089] In the above embodiments, by setting the cutter head fixing device 1 and the cutter head transfer device 2 on the drilling machine, in specific operation, the configured mobile feeding device 3 can transport the pre-placed cutter head on it to the cutter head transfer device 2, and then the cutter head transfer device 2 places the cutter head on the cutter head fixing device 1. After the drill bit on the cutter head is replaced by the drilling machine, the cutter head transfer device 2 takes the cutter head out of the cutter head fixing device 1 and transfers it to the mobile feeding device 3. Then, the cutter head that is worn or has reached the preset life can be moved to the recycling point by the mobile feeding device 3. Therefore, compared with the traditional manual replacement method, the automatic cutterhead changing system 100 of the above embodiment can not only significantly reduce the cost of manual intervention, but also avoid the problems of high equipment cost and low efficiency caused by the configuration of robotic arms. Thus, when performing cutterhead changing operations on multiple spindles of the drilling rig 10, the configuration method of this application has high overall efficiency and low equipment cost. This can solve the problems of low automation, low efficiency and high cost of cutterhead changing operation of drilling rig 10 in the prior art, and can further improve the construction of unmanned workshops and smart factories.

[0090] In one embodiment, the first positioning component 12 includes a positioning block 121 disposed on the base plate 11, the positioning block 121 being used to abut against the outer surface of the cutter head.

[0091] Please see Figure 2 and Figure 3 The base plate 11 is provided with a positioning block 121. Specifically, the positioning block 121 may include two side positioning blocks 121 and an end positioning block 121 located at the end of the base plate 11 away from the cutter head transfer device 2. The positioning block 121 may be provided with a common inclined guide structure 3321 so that when the cutter head is transferred from the cutter head transfer device 2 to the cutter head fixing device 1, the cutter head can be quickly and accurately positioned by the positioning block 121, thereby ensuring the positional accuracy of the cutter head.

[0092] In one embodiment, the first fixing component 13 includes an electromagnet 131 disposed on the side of the positioning block 121, and the side of the cutter disc is provided with a suction part 201 that can be attracted by the electromagnet 131.

[0093] Please see Figure 3 and Figure 4 The cutter head is provided with a suction part 201 that can attract the electromagnet 131. Specifically, the suction part 201 can be an iron plate-like structure that is provided on the side of the cutter head and extends upward. When the cutter head is positioned, the electromagnet 131 provided on the side of the positioning block 121 is energized to generate magnetic force to attract and fix the cutter head. In this way, the cutter head can be prevented from shaking or shifting during the tool changing process, thus improving the success rate and stability of the drilling rig 10 when changing tools.

[0094] In one embodiment, the first fixing component 13 further includes a sensing mechanism 132, and the cutter head is provided with an identification part 202 that can be identified by the sensing mechanism 132.

[0095] Please see Figure 3 and Figure 4 The sensing mechanism 132 can be a photoelectric sensor, and correspondingly, the identification unit 202 can be any part on the cutter head that can reflect photoelectric signals. The sensing mechanism 132 can also be an electromagnetic induction device, in which case the identification unit 202 can be an NFC (Near Field Communication) tag. When the cutter head is transferred to the predetermined position on the cutter head fixing device 1, the identification unit 202 on the cutter head is identified by the sensing mechanism 132, the cutter head fixing device 1 is activated and the cutter head is fixed, thus improving the automation level and stability of the automatic cutter head changing system 100.

[0096] In one embodiment, the cutter head transfer device 2 further includes a transfer drive 24, which is connected to the slide 22 and is used to drive the slide 22 to move on the support frame 21.

[0097] Please see Figure 2 and Figure 3 The transfer drive component 24 can drive the slide table 22 to reciprocate on the support frame 21. The transfer drive component 24 can be any of the following mechanisms: pneumatically controlled telescopic cylinder, motor-driven gear and rack mechanism, or motor-driven lead screw and nut mechanism. The power source of the transfer drive component 24 is fixed on the cutter head transfer device 2, and the moving parts of the transfer drive component 24 are fixedly connected to the slide table 22. In this embodiment of the invention, the specific type of the transfer drive component 24 is not limited. Regarding the specific connection method of the transfer drive component 24, those skilled in the art can easily connect it according to the specific mechanism type, and it will not be described in detail here. By using the connection between the transfer drive component 24 and the slide table 22, the slide table 22 can be continuously and automatically transferred between different workstations, improving the efficiency of material transfer, thereby improving the automation level of the automatic cutter head changing system 100, optimizing the trajectory of the cutter head moving in the cutter head transfer device 2, and thus improving the system efficiency and saving costs.

[0098] In one embodiment, please refer to Figure 2 and Figure 3The cutter head loading and unloading assembly 23 is connected to the support frame 21 and is located above the loading and unloading part 211. The cutter head loading and unloading assembly 23 includes a loading and unloading drive component 231 and an adsorption component 232 for picking up the cutter head. The adsorption component 232 is located at the output end of the loading and unloading drive component 231. The adsorption component 232 can be a suction cup or an electromagnet 131. In conjunction with the above embodiment, the electromagnet 131 can be used to adsorb the iron plate-like structure that is set on the side of the cutter head and extends upward. The loading and unloading drive component 231 can be a telescopic cylinder, a telescopic hydraulic cylinder, or a telescopic motor. The loading and unloading drive component 231 can drive the adsorption component 232 to drive the cutter head to reciprocate between the positioning component and the loading and unloading part 211.

[0099] The cutter head loading and unloading assembly 23 can efficiently load and unload the cutter head, improving the automation level of the automatic cutter head changing system 100, and thus increasing the operating rate of the automatic cutter head changing system 100.

[0100] In one embodiment, the feeding assembly 33 includes a feeding frame 331 and at least one support plate 332. The feeding frame 331 can be assembled from profiles. The support plate 332 is horizontally arranged on the feeding frame 331, and a transmission belt mechanism 333 is wound around the support plate 332. The transmission belt mechanism 333 can include a belt structure and a motor connected to the belt structure. When the motor rotates, the belt rotates synchronously. In this way, the motor in the transmission belt mechanism 333 can drive the cutter head placed on the belt to move along the length direction of the support plate 332, which can improve efficiency and save space during the process of storing and retrieving the cutter head.

[0101] Please see Figure 5 The position of the cutter head placed on the support plate 332 is moved by the transmission belt mechanism 333, which improves the efficiency of the cutter head picking and placing.

[0102] In one embodiment, the feeding assembly 33 includes a plurality of bearing plates 332, all of which are slidably mounted on the feeding frame 331 in a vertical direction. The moving vehicle 31 is provided with a lifting component 311, which is used to push the bearing plates 332 to move up and down.

[0103] Please see Figure 5 Multiple support plates 332 are arranged vertically and slidably mounted on the feeding frame 331. The moving vehicle 31 is equipped with a lifting component 311. When the lifting component 311 is raised, it can push each support plate 332 to move upward together. In this way, after one support plate 332 is used for material replacement, another support plate 332 can be used for material replacement. In this embodiment, by setting multiple support plates 332, the storage capacity of the cutter head of the feeding component 33 is increased. Furthermore, by using the lifting component 311 to push the support plates 332 to move and switch the support plates 332 for material supply, the feeding efficiency and the adaptability of the automatic cutter head changing system 100 are further improved.

[0104] In one embodiment, a guide rod 3311 is provided on the feeding frame 331 in a vertical direction, and a guide structure 3321 is provided on the bearing plate 332, with the guide structure 3321 sleeved on the guide rod 3311.

[0105] Please see Figure 5 By utilizing the cooperation between the guide structure 3321 and the guide rod 3311, the movement accuracy of the bearing plate 332 is improved. Specifically, the guide rod 3311 can be a guide post, and the guide structure 3321 can be a guide sleeve.

[0106] In one application scenario, the workflow of the automatic tool changer system 100 is illustrated below:

[0107] In the initial state, each axis of the drilling rig 10 has a cutter head containing old tools at its corresponding position, while the feed assembly 33's support plate 332 has a cutter head containing new tools.

[0108] Subsequently, the moving carriage 31 moves and drives the outlet end of the feeding assembly 33 to the side of the loading section 212. At this time, the slide table 22 is located above the loading section 212 and the loading and unloading section 211. The cutter head transfer assembly 32 pushes the cutter head containing the new cutter head to the position of the slide table 22 above the loading section 212. At the same time, the cutter head loading and unloading assembly 23 drives the cutter head containing the old cutter head to the position of the slide table 22 above the loading and unloading section 211. After the two cutter heads are stably placed on the slide table 22, the transfer drive 24 drives the slide table 22 to move above the unloading section 213 and the loading and unloading section 211.

[0109] After the slide table 22 has switched positions, the cutter head loading and unloading assembly 23 drives the cutter head containing the new cutter head from the slide table 22 to the base plate 11 of the cutter head fixing device 1, so that the cutter head containing the new cutter head contacts and positions itself with the first positioning assembly 12. The moving carriage 31 moves the outlet end of the feeding assembly 33 to the side of the unloading section 213, and then the cutter head transfer assembly 32 transfers the cutter head containing the old cutter head on the slide table 22 to the supporting plate 332. This completes the cutter head replacement of one of the spindle sections of the drilling rig 10. The moving carriage 31 can then move to the next loading section 212 where the cutter head needs to be replaced and repeat the above operation.

[0110] It should be noted that the mobile feeding device 3 in this application can be used in conjunction with multiple cutter head fixing devices 1 and cutter head transfer devices 2. After the cutter head of one drilling machine 10 has been replaced, the mobile feeding device 3 can continue to move to the next drilling machine 10 to perform cutter head replacement operation. In this way, the cutting efficiency is improved and production costs are saved.

[0111] In one embodiment, the automatic tool changer system 100 further includes a cleaning chuck assembly 4, a pressure foot replacement assembly 5, and a runout measuring instrument 6, all of which are mounted on the base plate 11.

[0112] Please see Figure 2 The cleaning chuck assembly 4, the pressure foot replacement assembly 5, and the runout measuring instrument 6 can be arranged on the base plate 11. After the cutter head is replaced, before the drilling machine 10 starts production with the cutter head, it needs to maintain the spindle chuck and confirm that the spindle is in good condition. Finally, the pressure foot on the spindle must be replaced before the cutter can be removed and production can begin.

[0113] In this embodiment, the spindle chuck can be cleaned first by cleaning the chuck assembly 4. After cleaning, the spindle chuck is measured on the runout measuring instrument 6 to check if the spindle runout is within the normal range. If the runout is within the normal range, the process can continue; otherwise, the machine will issue an alarm. After confirming the spindle runout status, the drilling rig 10 uses an automatic pressure foot changing device to replace the pressure feet on the spindle chip suction cover. Finally, the spindle picks up the cutting tool from the cutter head for production. This embodiment maintains and tests the spindle status of the drilling rig 10 through the above series of steps, improving the automation level and tool changing accuracy of the automatic tool changer system 100.

[0114] In another embodiment, this application also provides a processing device, specifically, the processing device includes the automatic tool changer system 100 of any of the above embodiments, wherein the processing device may include, but is not limited to, drilling equipment, or other types of equipment that require tool change; it is understood that, based on the advantages of the automatic tool changer system in the above embodiments, such as high degree of automation, high efficiency and low cost, the processing device in this embodiment also has the advantages of high degree of automation, high efficiency and low cost. In addition, by configuring the automatic tool changer system 100 on the processing device, the automation of the entire production process can be greatly improved, which can further improve the construction of smart factories and accelerate the construction of Industry 5.0.

[0115] 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, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
