Description

Technical Field

[0001] This invention relates to the field of automated operation technology, and in particular to a polishing machine material changing device and a polishing machine. Background Technology

[0002] CNC grinding and polishing equipment, used for grinding and polishing metals, glass, ceramics, plastics, and other products, is widely used in industries such as 3C electronics, new energy, and automobiles. However, traditional polishing equipment is usually semi-automatic, requiring manual stripping and application of materials during material changes or loading, leading to increased labor costs and low production line efficiency. Therefore, automatically replacing manual labor with consumables for polishing head replacement, and achieving automated integration of equipment and even production lines, has been a pressing challenge for the industry. Summary of the Invention

[0003] Therefore, it is necessary to provide a polishing machine material changing device and a polishing machine that can achieve effective automated material feeding, improve work efficiency, and at the same time help reduce labor costs.

[0004] A polishing machine material changing device for changing the polishing head on a polishing component includes: a support platform for relative movement with the polishing head; a material-tearing mechanism disposed on the support platform, which removes old consumables from the polishing head by utilizing the relative movement between the support platform and the polishing head; and a material-feeding mechanism disposed on the support platform and spaced apart from the material-tearing mechanism, which provides new consumables for the polishing head to adhere.

[0005] In the aforementioned polishing machine material changing device, during automatic polishing operations, when the polishing head needs a material change, the polishing head moves towards the tearing mechanism. At this time, the tearing mechanism uses the relative movement between the support platform and the polishing head to remove the old consumable material from the polishing head. After the old consumable material is removed, the relative movement between the support platform and the polishing head positions the polishing head at the feeding mechanism. The feeding mechanism then provides new consumable material to the polishing head for automatic application, thus achieving automatic material changing for the polishing head. Therefore, this polishing machine material changing device operates entirely automatically and mechanically, both during the stripping and feeding processes, completely replacing manual labor and significantly reducing labor costs. Simultaneously, the fully automated feeding operation effectively improves the feeding efficiency of the polishing head and accelerates the processing cycle of the polishing production line.

[0006] In one embodiment, the tearing mechanism includes a support member and a scraping member. The scraping member is mounted on the support platform via the support member and is used to insert between the polishing head and the old consumable.

[0007] In one embodiment, the polishing machine material changing device further includes a first detection component, which is used to detect whether the old consumable or the new consumable is present on the polishing head.

[0008] In one embodiment, the first detection component includes a trigger, a first elastic element, and a sensor. The trigger is disposed on the tearing mechanism via the first elastic element, and the sensor is located below the trigger. When the polishing head moves to the detection position, the new or old consumable material of the polishing head can press down on the trigger so that one end of the trigger moves down to engage with the sensor.

[0009] In one embodiment, the polishing machine material changing device further includes a second detection component, which is used to acquire the rotation information of the polishing head so that the polishing head rotates to a preset angle.

[0010] In one embodiment, the polishing machine material changing device further includes a receiving box disposed on the support platform to receive the old consumables scraped off by the tearing mechanism.

[0011] In one embodiment, the feeding mechanism includes a lifting structure, a first driver, and a material cylinder structure disposed on the support platform. The material cylinder structure has a rotation axis and a receiving groove extending along the axial direction of the rotation axis. The first driver is used to drive the material cylinder structure to rotate about the rotation axis so that the receiving groove switches at least between a filling station and a feeding station. The lifting structure is used to drive the uppermost layer of new consumables in the receiving groove to the feeding height.

[0012] In one embodiment, the barrel structure includes a barrel body and at least three adjusting components. All of the adjusting components are circumferentially spaced on the barrel body around the receiving groove. At least a portion of the adjusting components extends into the receiving groove and can be moved and adjusted radially along the receiving groove.

[0013] In one embodiment, the lifting structure includes a support beam, a supporting component, and a second actuator. The supporting component includes a support member, a second elastic member, and a base disposed on the support beam. The support member is disposed on the base via the second elastic member. The support member extends at least partially into the receiving groove to support the new consumable. The addition or removal of new consumables on the support member can cause the second elastic member to undergo elastic deformation to adjust the height position of the support member on the base. The second actuator is used to drive the support beam to move up and down.

[0014] A polishing machine includes a polishing component and a polishing machine material changing device as described in any of the above claims, wherein the polishing component has a polishing head that rotates about its own axis.

[0015] The aforementioned polishing machine employs the above-mentioned material changing device. During automatic polishing operations, when the polishing head needs material changing, it moves towards the tearing mechanism. At this time, the tearing mechanism uses the relative movement between the support platform and the polishing head to remove the old consumable material from the polishing head. After the old consumable material is removed, the relative movement between the support platform and the polishing head positions the polishing head at the feeding mechanism. The feeding mechanism then provides new consumable material to the polishing head for automatic application, thus achieving automatic material changing for the polishing head. Therefore, this polishing machine's material changing device operates entirely automatically, both during the stripping and feeding processes, completely replacing manual labor and significantly reducing labor costs. Simultaneously, the fully automated feeding operation effectively improves the feeding efficiency of the polishing head and accelerates the processing cycle of the polishing production line.

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 6A polishing machine material changing device is disclosed for changing the material on the polishing head 710 of a polishing component 700. The polishing machine material changing device includes: a support platform 100, a material-tearing mechanism 200, and a feeding mechanism 300. The support platform 100 is designed to have relative movement with the polishing head 710. The material-tearing mechanism 200 is disposed on the support platform 100 and, utilizing the relative movement between the support platform 100 and the polishing head 710, removes the old consumable material 810 from the polishing head 710. The feeding mechanism 300 is disposed on the support platform 100 and spaced apart from the material-tearing mechanism 200, and is used to provide new consumable material 800 for adhesion to the polishing head 710.

[0036] In the aforementioned polishing machine material changing device, during automatic polishing operations, when the polishing head 710 needs material changing, it moves towards the tearing mechanism 200. At this time, the tearing mechanism 200 uses the relative movement between the support platform 100 and the polishing head 710 to remove the old consumable material 810 from the polishing head 710. After the old consumable material 810 is removed, the relative movement between the support platform 100 and the polishing head 710 positions the polishing head 710 at the feeding mechanism 300. The feeding mechanism 300 then provides new consumable material 800 to the polishing head 710 for automatic application, thus achieving automatic material changing for the polishing head 710. Therefore, this polishing machine material changing device operates automatically and mechanically in both the stripping and feeding processes, completely replacing manual labor and significantly reducing labor costs. Simultaneously, the fully automated feeding operation effectively improves the feeding efficiency of the polishing head 710 and accelerates the processing cycle of the polishing production line.

[0037] It should be noted that the relative movement between the support platform 100 and the polishing head 710 should be understood as at least one of them having a movement function. For example, the support platform 100 can move toward or away from the polishing head 710; or, the polishing head 710 can move toward or away from the support platform 100, thereby achieving relative movement between the two. Furthermore, relative movement between the two also includes relative rotation. For example, the polishing head 710 can rotate about a certain axis of the polishing component 700, resulting in relative rotation with the support platform 100. Therefore, when the tearing mechanism 200 partially abuts against the old consumable 810 on the polishing head 710, it can effectively tear off the old consumable 810.

[0038] When the bearing platform 100 can move relative to the polishing head 710, telescopic devices such as pneumatic cylinders, hydraulic cylinders, and electric cylinders can be used to drive the bearing platform 100 to move relative to the polishing head 710; or a combination of devices such as a motor and lead screw or a motor and rollers can be used to drive the bearing platform 100 to move toward or away from the polishing head 710.

[0039] It should also be noted that when the tearing mechanism 200 removes the old consumable material 810 from the polishing head 710, the relative movement between the support platform 100 and the polishing head 710 provides the tearing mechanism 200 with the force to remove the old consumable material 810, thus achieving a stable tearing effect. The old consumable material 810 refers to consumable material whose surface has become worn and can no longer be used for polishing after a period of operation; the new consumable material 800 refers to consumable material that still has polishing properties, or it can be understood as unused consumable material. Whether it is the old consumable material 810 or the new consumable material 800, Velcro can be used between them when attaching them to the polishing head 710.

[0040] In addition, the number of feeding mechanisms 300 can be one or more. Multiple feeding mechanisms 300 are arranged side by side and spaced apart on the support table 100, so that new consumables 800 can be provided to multiple polishing heads 710 at the same time.

[0041] Further, please refer to Figure 8 and Figure 9 The tearing mechanism 200 includes a support member 220 and a scraper member 210. The scraper member 210 is mounted on the support platform 100 via the support member 220 and is used to insert between the polishing head 710 and the old consumable material 810. For ease of understanding, the movement of the support platform is used as an example. During the tearing process, the support platform moves relative to the polishing head 710 under external pushing, causing the scraper member 210 to insert between the polishing head 710 and the old consumable material 810; as the support platform continues to be pushed, the scraper member 210 continues to insert between the polishing head 710 and the old consumable material 810 until the old consumable material 810 falls off the polishing head 710.

[0042] Of course, during the tearing process, the scraper 210 remains stationary, while the polishing head 710 moves toward the scraper 210 under external pushing, so that the scraper 210 is inserted between the polishing head 710 and the old consumable 810.

[0043] It should be noted that the scraper 210 can be in a fixed state or a movable state on the support 220. When the scraper 210 is in a movable state, a motor or other equipment can be installed so that the scraper 210 can swing left and right while scraping material, thereby expanding the scraping range of the scraper 210 and preventing the old consumable 810 from failing to be peeled off due to its edges sticking to the polishing head 710.

[0044] Meanwhile, when the shovel component 210 is fixed on the support component 220, the connection method between it and the support component 220 can be, but is not limited to, welding, snap-fitting, riveting, bonding, and integral molding. Among them, integral molding methods include bending, injection molding, and die casting.

[0045] Furthermore, please refer to Figure 9To facilitate the insertion of the scraper 210 between the polishing head 710 and the old consumable 810, the end of the scraper 210 away from the support member 220 is provided with an insertion portion 212 that is either conical or approximately tapered. Furthermore, the thickness of this insertion portion 212 can be configured such that the portion further away from the support member 220 is thinner.

[0046] In one embodiment, please refer to Figure 2 and Figure 3 The polishing machine's material changing device also includes a first detection component 400. The first detection component 400 is used to detect whether there is old consumable 810 or new consumable 800 on the polishing head 710. After the polishing head 710 completes the material removal process, the first detection component 400 can detect whether there is still old consumable 810 on the polishing head 710. If the first detection component 400 detects old consumable 810 on the polishing head 710, it indicates that the material removal was unsuccessful and needs to be repeated or manually intervened; if the first detection component 400 does not detect old consumable 810 on the polishing head 710, it indicates that the material removal was successful and the next material loading process can proceed.

[0047] Similarly, after the polishing head 710 completes the feeding process, the first detection component 400 can detect whether there is new consumable material 800 on the polishing head 710. If the first detection component 400 detects new consumable material 800 on the polishing head 710, it indicates that the feeding is successful and the next grinding and polishing process can proceed; if the first detection component 400 does not detect new consumable material 800 on the polishing head 710, it indicates that the feeding is successful and it needs to be returned for re-feeding or manual intervention is required. In this way, by using the first detection component 400, the success rate of tearing or feeding material into the polishing head 710 can be effectively controlled, ensuring that the automatic material changing operation is stable and orderly.

[0048] Further, please refer to Figure 3The first detection component 400 includes a trigger 410, a first elastic element 420, and a sensor 430. The trigger 410 is mounted on the tearing mechanism 200 via the first elastic element 420. The sensor 430 is located below the trigger 410. When the polishing head 710 moves to the detection position, the new or old consumable material 800 of the polishing head 710 can press down on the trigger 410, causing one end of the trigger 410 to move down and engage with the sensor 430. Therefore, the polishing head 710 moves to the detection position to detect whether tearing or feeding is successful. If there is no old or new consumable material 810 on the polishing head 710, the polishing head 710 in the detection position cannot press down on the trigger 410; or it cannot press one end of the trigger 410 down to engage with the sensor 430. At this time, sensor 430 cannot obtain a sensing signal; if there is old consumable 810 or new consumable 800 on polishing head 710, the old consumable 810 or new consumable 800 presses down on trigger 410 due to its own thickness, causing one end of trigger 410 to move down to cooperate with sensor 430 and obtain a sensing signal, indicating that the material tearing was unsuccessful or the material loading was successful, realizing intelligent detection and reducing the error rate of polishing machine material changing device.

[0049] It should be noted that the detection position refers to a location where the polishing head 710 is positioned, with a certain gap between the adhesive surface of the polishing head 710 and the trigger 410, preventing the polishing head 710 from pressing down on the trigger 410. Of course, the polishing head 710 can press down on the trigger 410 at this position, but the pressure will not be enough to bring one end of the trigger 410 into the sensing range of the sensor 430. If there is an old consumable 810 or a new consumable 800 on the polishing head 710, the old consumable 810 or the new consumable 800 can press down on the trigger 410, allowing one end of the trigger 410 to move down into the sensing range of the sensor 430.

[0050] In addition, there are several ways to select the detection position. For example, a position can be selected above the trigger 410, with a distance between this position and one end of the trigger 410. This distance should be less than the thickness of either the new consumable 800 or the old consumable 810 (for example, less than the thickness of the old consumable 810). Of course, the distance between the detection position and the trigger 410 can also be set to zero. Alternatively, a position can be selected below the top of the trigger 410, where the polishing head 710 can press down on the trigger 410, but cannot drive one end of the trigger 410 to engage with the sensor 430.

[0051] It should also be noted that the sensing signals acquired by the first detection component 400 should be sent to the control module, such as a Programmable Logic Controller (PLC), a microcontroller, or an Electronic Control Unit (ECU). The control module acquires the corresponding sensing signals to determine whether the material tearing or loading is successful, so as to control the polishing machine to perform the corresponding actions.

[0052] Furthermore, a first elastic element 420 is disposed between the trigger element 410 and the tearing mechanism 200, allowing the trigger element 410 to be elastically supported on the tearing mechanism 200. This enables the trigger element 410 to automatically return to its initial state when not pressed down, facilitating continued detection by the polishing head 710. The first elastic element 420 can be, but is not limited to, a spring, elastic rubber, or elastic metal sheet. When the first elastic element 420 is a spring, the spring is sleeved around the trigger element 410 and connected to the tearing mechanism 200 (specifically, the scraper element 210). Meanwhile, the sensor 430 can be a non-contact sensor 430 or a contact sensor 430.

[0053] Furthermore, please refer to Figure 9 The shovel component 210 has a through hole 211. A trigger component 410 passes through the through hole 211, and a first elastic component 420 is located between the trigger component 410 and the shovel component 210. A sensor 430 is connected to the support component 220 or the shovel component 210, with its sensing end located below the through hole 211. When the trigger component 410 moves downward by a preset displacement, one end of the trigger component 410 can engage with the sensor 430. Thus, by utilizing the through hole 211, the downward movement or rebound of the trigger component 410 becomes more stable, which helps improve the reliability of the detection results.

[0054] It should be noted that "preset displacement" should be understood as the amount of displacement of the polishing head 710, which is located at the detection position and has the new consumable 800 or the old consumable 810 pressing down the trigger 410.

[0055] In one embodiment, please refer to Figure 6 The polishing machine's material changing device also includes a second detection component 500. The second detection component 500 is used to acquire the rotation information of the polishing head 710, so that the polishing head 710 rotates to a preset angle. Thus, through the second detection component 500, the polishing head 710 can be guided to the preset angle, ensuring that the material-attaching posture of the polishing head 710 remains consistent each time, which helps improve the accuracy of automatic material changing.

[0056] It should be noted that, to ensure the polishing head 710 can rotate to a preset angle, a sensing object can be installed on the polishing head 710; alternatively, an existing structure on the polishing head 710 can be used as the sensing object. Using this sensing object as a reference, when the sensing object is detected, the rotation of the polishing head 710 is stopped, ensuring it is at the preset angle. For example, the polishing head 710 may have an eccentric wheel 720. The second detection component 500 obtains the rotation information of the polishing head 710 by detecting the eccentric wheel 720. When the second detection component 500 detects the protrusion 721 of the eccentric wheel 720 (e.g., contact with the protrusion 721), it sends a sensing signal to the control module, controlling the polishing head 710 to stop rotating.

[0057] Optionally, the second detection component 500 may be a contact sensor 430, such as a pressure sensor 430; or a photosensitive sensor 430, such as an infrared sensor 430.

[0058] In one embodiment, please refer to Figure 6 The polishing machine material changing device also includes a receiving box 600. The receiving box 600 is located on the support platform 100 to receive the old consumables 810 scraped off by the tearing mechanism 200, so as to facilitate the unified collection and cleaning of the old consumables 810.

[0059] In one embodiment, please refer to Figure 10 The feeding mechanism 300 includes a lifting structure 310, a first driver 320, and a cylinder structure 330 disposed on the support platform 100. The cylinder structure 330 has a rotation axis 3311 and a receiving groove 3312 extending along the axial direction of the rotation axis 3311. The first driver 320 is used to drive the cylinder structure 330 to rotate about the rotation axis 3311, so that the receiving groove 3312 switches at least between the filling station and the feeding station. The lifting structure 310 is used to drive the uppermost layer of new consumables 800 in the receiving groove 3312 to the feeding height.

[0060] During the automated operation, the first driver 320 drives the barrel structure 330 to rotate around the rotation axis 3311, causing the receiving tank 3312 to rotate to the feeding station, facilitating manual feeding of material into the receiving tank 3312. After feeding, the barrel structure 330 continues to rotate, causing the receiving tank 3312 to rotate to the loading station; then, the lifting structure 310 is activated, driving the new consumable material 800 in the receiving tank 3312 to rise, so that the uppermost layer of new consumable material 800 is lifted to the loading height, facilitating the polishing head 710 to automatically pick up the material in the receiving tank 3312, thereby completing the automated loading operation and ensuring the stable operation of the feeding and loading processes.

[0061] It should be noted that the number of receiving slots 3312 can be one or more. When there are multiple receiving slots 3312, the multiple receiving slots 3312 are arranged circumferentially around the rotation axis 3311.

[0062] It should also be noted that the first driver 320 is a motor, and when connected to the barrel structure 330, it can be connected by a gear set, a belt and roller combination structure, or a chain and gear combination structure.

[0063] Further, please refer to Figure 10 The feed cylinder structure 330 includes a feed cylinder body 331 and at least three adjusting components 332. All adjusting components 332 are circumferentially spaced on the feed cylinder body 331. At least a portion of each adjusting component 332 extends into the receiving groove 3312 and can be adjusted radially along the receiving groove 3312. Therefore, when the size of the new consumable 800 changes, the adjusting components 332 can be driven to move radially along the receiving groove 3312, changing the radial extension of the adjusting components 332 within the receiving groove 3312. This allows a portion of the adjusting components 332 to contact materials of different sizes, ensuring that new consumables 800 of different sizes can be stably contained within the receiving groove 3312. Thus, using the feed cylinder structure 330 of this application, while ensuring the stable operation of the feeding and loading processes, it can effectively accommodate materials of different sizes, improving the applicability of the equipment.

[0064] It should be noted that the adjusting component 332 can move radially along the receiving groove 3312 on the barrel body 331. There are several ways to achieve this. For example, the adjusting component 332 is connected to the barrel body 331 by a thread, and the adjusting component 332 moves on the barrel body 331 by rotation. Alternatively, the adjusting component 332 is connected to the barrel body 331 by a pin, and the pin is inserted into different pin holes so that the adjusting component 332 moves radially along the receiving groove 3312.

[0065] Meanwhile, the correspondence between the receiving slot 3312 and the adjustment component 332 is one-to-many, that is, each receiving slot 3312 is provided with at least three adjustment components 332.

[0066] To facilitate understanding of the radial and vertical directions of the receiving groove 3312, Figure 10 For example, the radial direction of the receiving groove 3312 is Figure 10 The direction indicated by any arrow in S1; the height direction of the receiving groove 3312 is... Figure 10 The direction pointed to by any arrow in S2.

[0067] Further, please refer to Figure 10The adjustment assembly 332 includes an adjustment member 3321 and a limiting member 3322 disposed on the adjustment member 3321. The limiting member 3322 is located within the receiving groove 3312 and extends along the axial direction of the rotation axis 3311. The adjustment member 3321 is movably disposed on the barrel body 331 and can be adjusted by radial movement along the receiving groove 3312. Therefore, when the size of the new consumable 800 changes, adjusting the adjustment member 3321 radially along the receiving groove 3312 causes the limiting member 3322 to move within the receiving groove 3312, changing the distance between the two limiting members. This allows the limiting member 3322 to abut against new consumables 800 of different sizes, ensuring that the barrel structure 330 can adapt to new consumables 800 of different sizes, thus expanding its application range.

[0068] It should be noted that the limiting member 3322 extends along the axis of rotation 3311 within the receiving groove 3312. Its purpose is to enable the limiting member 3322 to contact the new consumables 800 in different layers simultaneously, ensuring that the new consumables 800 in the receiving groove 3312 are all effectively limited.

[0069] In addition, the adjustment component 3321 can be installed on the barrel body 331 by, but is not limited to, threaded connection, pin connection, etc. When the adjustment component 3321 is installed on the barrel body 331 by pin connection, multiple rows of pin holes or a pin hole with an oblong design can be provided on the adjustment component 3321 and / or the barrel body 331.

[0070] Furthermore, please refer to Figure 10 The barrel body 331 is provided with at least three sliding grooves 3313. These three sliding grooves 3313 are arranged at intervals around the circumference of the receiving groove 3312 and extend radially along the receiving groove 3312. An adjusting member 3321 is slidably disposed within the sliding groove 3313. Thus, by placing the adjusting member 3321 within the sliding groove 3313, the radial adjustment of the adjusting member 3321 along the receiving groove 3312 becomes smoother, thereby making the feeding operation of new consumables 800 of different sizes more convenient.

[0071] In one embodiment, please refer to Figure 10 The adjusting component 332 is equipped with a baffle 333. The baffle 333 extends partially into the receiving groove 3312 to prevent two or more new consumables 800 from being removed from the receiving groove 3312 simultaneously. Because there is some adhesion between the new consumables 800, when the top layer of new consumables 800 is grasped, lower layers of new consumables 800 may occasionally be pulled out, making it impossible to automatically feed them one by one. Therefore, this embodiment provides a baffle 333, with a portion extending into the receiving groove 3312, allowing only the top layer of new consumables 800 to be removed, thus preventing two or more new consumables 800 from being removed from the receiving groove 3312 simultaneously and achieving automatic feeding of new consumables 800 one by one.

[0072] In addition, the baffle 333 is provided on the adjustment assembly 332 so that the baffle 333 can move together with the adjustment assembly 332 along the radial direction of the receiving groove 3312, ensuring that the baffle 333 can act on new consumables 800 of different sizes.

[0073] Further, please refer to Figure 11 The baffle 333 includes a connecting portion 3331 and a baffle portion 3332 disposed on the connecting portion 3331. The connecting portion 3331 is connected to the adjusting component 332. The baffle portion 3332 is located in the receiving groove 3312 and is used to abut against the new consumable 800 in the receiving groove 3312 to separate the new consumable 800 adhering together. Therefore, when the uppermost new consumable 800 is taken out and brings out the lower new consumable 800, the baffle portion 3332 will abut against the lower new consumable 800. Since the adhesion force between the uppermost new consumable 800 and the lower new consumable 800 is much smaller than the bonding force between the uppermost new consumable 800 and the polishing head 710, the lower new consumable 800 can easily detach from the uppermost new consumable 800 under the action of the baffle portion 3332, ensuring that the new consumables 800 are automatically fed one by one, improving the feeding stability.

[0074] Optionally, the connection method between the retaining part 3332 and the connecting part 3331 can be, but is not limited to, bolt connection, welding, riveting, bonding, or integral molding. Among them, the integral molding method can be bending, injection molding, extrusion, etc.

[0075] Furthermore, please refer to Figure 11 The baffle part 3332 has a first end 33321 and a second end 33322 disposed opposite to each other. The second end 33322 is connected to the connecting part 3331. The baffle part 3332 is inclined on the connecting part 3331. In the height direction of the receiving groove 3312, the first end 33321 is higher than the second end 33322, and the first end 33321 is closer to the center of the receiving groove 3312 than the second end 33322. Therefore, the baffle part 3332 is inclined upward, so that when it comes into contact with the new consumable 800, it can effectively separate from the topmost new consumable 800, while ensuring that the topmost new consumable 800 passes smoothly, thus ensuring the orderly operation of automatic feeding.

[0076] It should be noted that the baffle 3332 can be designed with a certain degree of elasticity, such as steel sheets or plastic sheets. In this way, when the new consumable 800 passes through, while ensuring effective separation between the new consumable 800 and the new consumable 800, the uppermost new consumable 800 can also pass through stably through its own elastic deformation function.

[0077] In one embodiment, please refer to Figure 10The feed cylinder structure 330 also includes a partition 334 for supporting the new consumable 800. The partition 334 can move within the receiving groove 3312 along the axis of rotation 3311. Therefore, when the new consumable 800 is placed in the receiving groove 3312, the new consumable 800 can be moved along the axis of rotation 3311 by lifting the partition 334, so that the uppermost new consumable 800 is always at the feeding height, ensuring stable automatic feeding.

[0078] It should be noted that, in order to lift the partition 334, a through hole 3315 can be provided at the bottom of the receiving groove 3312; or a hole can be opened on the side wall of the receiving groove 3312 so that the telescopic shaft of equipment such as cylinder, hydraulic cylinder or electric cylinder can pass through and connect to the partition 334.

[0079] It should also be noted that at least three guide grooves 3341 are spaced apart on the edge of the partition 334. When the adjusting component 332 is activated, the limiting member 3322 can move within the guide grooves 3341 to ensure smoother operation of the adjusting component 332. At the same time, it also allows the partition 334 to move along the limiting member 3322, improving the stability of the movement of the partition 334.

[0080] In one embodiment, please refer to Figure 10 The barrel structure 330 also includes a sensor 335. The sensor 335 is used to obtain the initial position of the barrel body 331. In this way, by obtaining the initial position of the barrel body 331 through the sensor 335, the rotation of the barrel structure 330 is brought to zero, avoiding the stepper motor from losing steps and causing the receiving slot 3312 to fail to move accurately to the loading station or the feeding station.

[0081] It should be noted that the sensor 335 can be a pressure sensor 430 or a photosensitive sensor 430, etc. There is no specific limitation, as long as it can sense the initial position of the barrel body 331.

[0082] In one embodiment, please refer to Figure 10 There are at least two receiving slots 3312. These at least two receiving slots 3312 are arranged circumferentially around the rotation axis 3311. When the cylinder body 331 rotates around the rotation axis 3311, one receiving slot 3312 is located at the feeding station, and the other receiving slot 3312 is located at the loading station. Therefore, when one receiving slot 3312 moves to the loading station for feeding, the other receiving slot 3312 is at the feeding station, at which time the operator can perform the feeding operation. This allows the loading and feeding processes to be performed simultaneously, effectively improving loading efficiency.

[0083] It should be noted that the number of receiving slots 3312 can be two, three, or more. When there are two or more receiving slots 3312, at least one receiving slot 3312 is neither in the loading station nor the replenishing station; that is, the receiving slot 3312 is in the waiting station. After the new consumable 800 in the loading station has been taken out, the receiving slot 3312 will rotate into the loading station.

[0084] In one embodiment, please refer to Figure 10 The barrel body 331 includes a top cover 3316 and a bottom plate 3318 that are spaced apart from each other, and at least three support rods 3317 connected between the top cover 3316 and the bottom plate 3318. The top cover 3316 has an opening 3314, and the at least three support rods 3317 are arranged circumferentially around the opening 3314 to form a receiving groove 3312. This simplifies the structure of the barrel body 331 and reduces manufacturing costs while ensuring stable feeding.

[0085] In one embodiment, please refer to Figures 12 to 14 The lifting structure 310 includes a support beam 311, a supporting component 312, and a second actuator 313. The supporting component 312 includes a supporting member 3121, a second elastic member 3122, and a base 3123 disposed on the support beam 311. The supporting member 3121 is disposed on the base 3123 via the second elastic member 3122. The supporting member 3121 extends at least partially into the receiving groove 3312 to support new consumables 800. The addition or removal of new consumables 800 on the supporting member 3121 can drive the second elastic member 3122 to undergo elastic deformation to adjust the height position of the supporting member 3121 on the base 3123. The second actuator 313 is used to drive the support beam 311 to rise and fall.

[0086] During the feeding process, the second drive 313 is activated, causing the support beam 311 to rise and fall, which in turn moves the support member 3121 up and down, so that the top layer of new consumables 800 is moved back to the feeding height to achieve stable automatic feeding. Since a second elastic member 3122 is provided between the support member 3121 and the base 3123, during the replenishment of new consumables 800, if there is a shortage of new consumables 800, the force on the second elastic member 3122 is relatively reduced, and its elastic deformation is reduced, so that the support member 3121 is adjusted higher accordingly under the action of the second elastic member 3122; if there is an oversupply of new consumables 800, the force on the second elastic member 3122 increases, and its elastic deformation increases, so that the support member 3121 is adjusted lower accordingly under the action of the second elastic member 3122. Thus, by utilizing the elastic deformation of the second elastic element 3122, the height of the support element 3121 can be adaptively adjusted according to the increase or decrease in the quantity of new consumables 800, ensuring that the top layer of new consumables 800 is always at the feeding height. This effectively solves the problem of inaccurate feeding caused by insufficient or excessive feeding of new consumables 800, ensuring continuous and stable operation of automated work. In addition, the second elastic element 3122 is set between the support element 3121 and the base 3123, providing a certain buffer space between them, ensuring more stable feeding. For example, it can prevent rigid contact between the support element 3121 and the polishing head 710, which could easily lead to structural damage.

[0087] It should be noted that after the second drive 313 lifts the last new consumable 800 on the support 3121 to the feeding height and removes it, the second drive 313 retracts, causing the support 3121 to return to its initial position. At this time, the support 3121 needs to be manually replenished with new consumable 800. When replenishing the new consumable 800, it is easy to place too few or too many, resulting in the top layer of new consumable 800 on the support 3121 being lower or higher than the feeding height. "Too few or too many" refers to errors that occur during manual operation, usually involving placing one or two fewer or more new consumables 800, and not a large number of fewer or more.

[0088] Therefore, in this embodiment, a second elastic element 3122 is provided between the support 3121 and the base 3123. The deformation of the second elastic element 3122 is used to compensate for the material height difference caused by insufficient or excessive material placement, thereby giving the automated production line a higher fault tolerance rate and ensuring stable and orderly automatic feeding. The second elastic element 3122 can be, but is not limited to, a spring, elastic rubber, elastic metal sheet, etc.

[0089] In addition, please refer to Figure 6A third detection component 314 can be installed in the lifting structure 310 to determine whether there is new consumable material 800 or a preset quantity of new consumable material 800 in the receiving slot 3312. For example, the third detection component 314 (e.g., a magnetic switch) above the second driver 313 can detect whether there is material or enough material above the support 3121. If there is almost no material above the support 3121, the signal of the third detection component 314 will not be blocked; for example, the magnetic switch will sense the cylinder slider 31251 and give a signal.

[0090] In addition, the second driver 313 can be a device with telescopic function such as a cylinder, hydraulic cylinder, or electric cylinder; it can also be a combination structure of a motor and rack, or a combination structure of a motor and crank-slider 31251 mechanism, etc.

[0091] Further, please refer to Figure 15 The second elastic element 3122 is a spring. One end of the spring abuts against the base 3123, and the other end abuts against the support 3121, meaning the spring is in a compressed state between the base 3123 and the support 3121. Thus, when there is an under- or over-filling of new consumable material 800, the compression of the spring compensates for the height difference caused by the under- or over-filling, effectively adjusting the top layer of new consumable material 800 and ensuring that the top layer of new consumable material 800 is always at or near the feeding height.

[0092] In other embodiments, the spring can be in a stretched state between the base 3123 and the support 3121, that is, the support 3121 is suspended on the base 3123 by the spring. When the new consumable 800 is underfilled or overfilled, the stretching of the spring is used to compensate for the height difference caused by the underfill or overfilling, so that the uppermost new consumable 800 is effectively adjusted, ensuring that the uppermost new consumable 800 is always at or near the feeding height.

[0093] Further, please refer to Figure 14 The base 3123 includes a protrusion 31232 and a fixing part 31231 disposed on the support beam 311. The protrusion 31232 is disposed on the fixing part 31231. The support member 3121 is partially located above the protrusion 31232, and a spring abuts against the support member 3121 and the protrusion 31232. This design ensures that the spring is stably compressed between the support member 3121 and the base 3123, guaranteeing the structural stability of the lifting mechanism.

[0094] Of course, to ensure greater stability of the spring between the support 3121 and the base 3123, positioning posts or positioning grooves can be provided on both the support 3121 and the base 3123. During assembly, the two ends of the spring can be respectively fitted onto the positioning posts or into the positioning grooves.

[0095] Optionally, the connection method between the fixing part 31231 and the protrusion 31232 can be, but is not limited to, bolt connection, snap-fit, riveting, welding, bonding, or integral molding. Among them, the integral molding method can be injection molding, die casting, extrusion, bending, or other processes.

[0096] For details, please refer to Figure 14 The fixing part 31231 and the protrusion 31232 are integrally formed structures, and the fixing part 31231 and the protrusion 31232 are in an "L" shape or approximately "L" shape.

[0097] In one embodiment, please refer to Figure 14 The supporting component 312 also includes a sliding component 3125. The sliding component 3125 is disposed between the supporting component 3121 and the base 3123. The sliding component 3125 is used to allow the supporting component 3121 to move relative to the base 3123 along the extension and retraction direction S of the second elastic member 3122. In this way, the sliding component 3125 makes the movement of the supporting component 3121 on the base 3123 more stable, and ensures that the height position adjustment of the supporting component 3121 is more stable.

[0098] It should be noted that there are various structural designs for the sliding component 3125. For example, the sliding component 3125 can be designed as a combination structure of slider 31251 and slide rail 31252, or a matching structure of slider and groove 3313.

[0099] Further, please refer to Figure 15 The sliding assembly 3125 includes a slide rail 31252 and a slider 31251 slidably disposed on the slide rail 31252. The slide rail 31252 is disposed on the base 3123 and extends along the extension and retraction direction S of the second elastic member 3122. The support member 3121 is disposed on the slider 31251. Thus, through the cooperation between the slider 31251 and the slide rail 31252, the movement direction of the support member 3121 relative to the base 3123 is consistent with the extension and retraction direction of the second elastic member 3122. This makes the position adjustment of the support member 3121 by the extension and retraction of the second elastic member 3122 more precise, which is beneficial to improving the feeding accuracy.

[0100] In one embodiment, please refer to Figure 14 The supporting component 312 also includes a pad 3124. The pad 3124 is disposed on the supporting component 3121 and is used to support the new consumable 800. Thus, the pad 3124 is disposed on the supporting component 3121 to facilitate stable support of the new consumable 800.

[0101] Optionally, the connection method of the pad 3124 to the support member 3121 may be, but is not limited to, adhesive, snap-fit, magnetic attraction, etc.

[0102] Further, please refer to Figure 14The support member 3121 includes a mounting portion 31211 and a supporting portion 31212 arranged at an angle. The mounting portion 31211 is mounted on the base 3123 via a second elastic member 3122, and the pad 3124 is disposed on the supporting portion 31212. Thus, in this embodiment, the support member 3121 is designed as two components arranged at an angle to each other, so that a portion of the support member 3121 extends out, enabling it to better support the new consumable 800.

[0103] Specifically, the mounting part 31211 and the supporting part 31212 are integrally formed structures, and the mounting part 31211 and the supporting part 31212 are in an "L" shape or approximately "L" shaped.

[0104] In one embodiment, please refer to Figure 12 There are at least two supporting components 312. All the supporting components 312 are arranged at intervals along the length L of the support beam 311, so that the lifting mechanism can simultaneously supply multiple new consumables 800, thereby improving the feeding efficiency.

[0105] In one embodiment, please refer to Figure 12 The lifting mechanism also includes a guide assembly 3126. The guide assembly 3126 is used to guide the lifting movement of the support beam 311, thereby making the movement of the support beam 311 more stable.

[0106] It should be noted that the guide component 3126 can be designed as a guide rail structure or as a guide groove 3341 structure, etc.

[0107] Specifically, the guide assembly 3126 includes a guide bearing 31261 and a guide post (not shown). The guide bearing 31261 is sleeved on the outside of the guide post to make the lifting and lowering of the support beam 311 more stable.

[0108] Additionally, please refer to Figure 15 The lifting mechanism also includes a waterproof cover 3127. The waterproof cover 3127 is installed over the support component 312 to prevent water from entering the support component 312 and causing corrosion and rust to the internal structure.

[0109] In one embodiment, a polishing machine includes a polishing component 700 and a polishing machine changing device as described in any of the above embodiments. The polishing component 700 has a polishing head 710 that rotates about its own axis.

[0110] The aforementioned polishing machine employs the above-mentioned material changing device. During automatic polishing operations, when the polishing head 710 needs material changing, it moves towards the tearing mechanism 200. At this time, the tearing mechanism 200 uses the relative movement between the support platform 100 and the polishing head 710 to remove the old consumable material 810 from the polishing head 710. After the old consumable material 810 is removed, the relative movement between the support platform 100 and the polishing head 710 positions the polishing head 710 at the feeding mechanism 300. The feeding mechanism 300 then provides new consumable material 800 to the polishing head 710 for automatic application, thus achieving automatic material changing for the polishing head 710. Therefore, this polishing machine's material changing device operates automatically and mechanically in both the stripping and feeding processes, completely replacing manual labor and significantly reducing labor costs. Simultaneously, the fully automated feeding operation effectively improves the feeding efficiency of the polishing head 710 and accelerates the processing cycle of the polishing production line.
