[0005] In a first aspect, embodiments of this application provide a gripper mechanism for stainless steel products, which includes a movable arm and a gripper assembly.

[0006] The gripper assembly includes an adsorption structure and a fixing structure, wherein the adsorption structure and the fixing structure are installed on the moving arm at intervals, and the adsorption structure is used to adsorb or release the stainless steel product.

[0007] Wherein, after the stainless steel product is released by the adsorption structure, the fixing structure is used to press against the stainless steel product to keep the stainless steel product stationary.

[0008] In some embodiments, the fixing structure includes a first driving member and a pressure head;

[0009] The first driving component is mounted on the moving arm, and the pressure head is connected to the first driving component in a transmission manner;

[0010] Under the drive of the first driving member, the pressure head can move along the height direction to approach or move away from the stainless steel product, thereby pressing or releasing the stainless steel product.

[0012] The connecting part is fixedly connected to the first driving member and is made of rigid material; the pressing part is connected to the side of the connecting part away from the first driving member.

[0013] The pressure-retaining part is made of a flexible material.

[0014] In some embodiments, the adsorption structure includes a second driving element and a suction cup;

[0015] The second driving component is mounted on the moving arm, and the suction cup is connected to the second driving component in a transmission manner;

[0016] Driven by the second driving member, the suction cup can move along the height direction to approach or move away from the stainless steel product, thereby adsorbing or releasing the stainless steel product.

[0017] In some embodiments, the adsorption structure includes a plurality of adsorption structures arranged at intervals;

[0018] The adsorption structures are used together to adsorb the stainless steel product.

[0019] In some embodiments, the gripper assembly further includes a connecting plate connected to the movable arm;

[0020] The fixing structure and the plurality of adsorption structures are connected at intervals to the connecting plate.

[0021] In some embodiments, the mobile arm includes an arm body and a mounting portion, the mounting portion being connected to one end of the arm body and extending along the height direction;

[0022] The connecting plate can be connected to different positions along the extension direction of the mounting part to adjust its own height position.

[0023] In some embodiments, both the movable arm and the gripper assembly include multiple units, with the ends of the multiple movable arms connected together, and one gripper assembly correspondingly mounted on one movable arm; the gripper mechanism further includes:

[0024] A drive structure is connected to the multiple movable arms for driving the multiple movable arms to rotate, thereby driving the multiple gripper assemblies to rotate.

[0025] In some embodiments, the drive structure includes a cam divider having an output shaft;

[0026] The output shaft is fixedly connected to the plurality of the movable arms so that the cam divider can drive the plurality of the movable arms to rotate intermittently.

[0027] Secondly, embodiments of this application provide a stainless steel edge grinding machine, which includes a machine base, a coarse grinding mechanism, a fine grinding mechanism, and a gripper mechanism as described above.

[0028] The coarse grinding mechanism is located on the machine base and includes a first placement component and a coarse grinding component. The first placement component has a coarse grinding station, and the coarse grinding component is used to coarsely grind the stainless steel product located at the coarse grinding station. The fine grinding mechanism is located on the machine base and includes a second placement component and a fine grinding component. The second placement component has a fine grinding station, and the fine grinding component is used to finely grind the stainless steel product located at the fine grinding station. The movable arm is located on the machine base and can drive the gripper component to move between the coarse grinding station and the fine grinding station.

[0029] After the stainless steel product is released by the adsorption structure into either the coarse grinding station or the fine grinding station, the fixing structure can press against the stainless steel product to make it stationary in either the coarse grinding station or the fine grinding station.

[0030] Based on the gripper mechanism and edge grinding machine for stainless steel products according to the embodiments of this application, when the stainless steel product is edge-grinding, for example when the coarse grinding component performs coarse grinding on the stainless steel product and the fine grinding component performs fine grinding on the stainless steel product, the fixing component can automatically press against the stainless steel product to prevent the stainless steel product from shifting. As a result, when the edge grinding operation is performed subsequently, the stainless steel product will remain stationary and will not shift, thereby ensuring the accuracy of edge grinding and ensuring the quality of the stainless steel product after edge grinding.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0040] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] Please refer to the following: Figures 1-3This application proposes a stainless steel edge grinding machine 100 for grinding the edges of stainless steel products to provide the surface smoothness and aesthetics of the edges of stainless steel products, and at the same time remove surface defects of the edges of stainless steel products. The stainless steel products may include stainless steel pots, stainless steel bowls and stainless steel basins, etc., and the type of stainless steel products is not specifically limited here.

[0043] In this embodiment of the application, the stainless steel product edge grinding machine 100 includes a machine base 10, a coarse grinding mechanism 20, a fine grinding mechanism 40, and a gripper mechanism 30.

[0044] The machine base 10 mainly serves to support the various mechanisms of the edge grinding machine 100. Specifically, the coarse grinding mechanism 20, the fine grinding mechanism 40, and the gripper mechanism 30 are respectively located on the machine base 10.

[0045] A rough grinding mechanism 20 is located on the machine base 10 and is used to rough grind the edges of stainless steel products. Specifically, the rough grinding mechanism 20 includes a first placement component 21 and a rough grinding component 22. The first placement component 21 is located on the machine base 10 and has a rough grinding station 21A, which is used to place stainless steel products, specifically the stainless steel products to be rough ground. The rough grinding component 22 is used to rough grind the stainless steel products located at the rough grinding station 21A.

[0046] A fine grinding mechanism 40 is mounted on the machine base 10 and is used to fine grind the edges of stainless steel products. Specifically, the fine grinding mechanism 40 includes a second placement assembly 41 and a fine grinding assembly 42. The second placement assembly 41 is mounted on the machine base 10 and has a fine grinding station 41A, which is used to place stainless steel products, specifically the stainless steel products to be finely ground. The fine grinding assembly 42 is mounted on the machine base 10 and is used to finely grind the stainless steel products located at the fine grinding station 41A.

[0047] It should be noted that the coarse grinding component 22 and the fine grinding component 42 can grind the same edge of the stainless steel product. That is, after the coarse grinding component 22 finishes grinding the edge, the fine grinding component 42 further grinds the edge to improve the grinding effect. Alternatively, the coarse grinding component 22 and the fine grinding component 42 can be used correspondingly according to the grinding requirements of different edges of the stainless steel product. That is, some edges have lower grinding requirements, so they can be ground by the coarse grinding component 22, while some edges have higher grinding requirements, so they can be ground by the fine grinding component 42. This embodiment does not specifically limit the grinding method. For better understanding, the difference between the fine grinding component 42 and the coarse grinding component 22 is that the diameter of the abrasive particles in the fine grinding component 42 is smaller than the diameter of the abrasive particles in the coarse grinding component 22. Therefore, the effects of coarse grinding and fine grinding can be distinguished after grinding.

[0048] The gripper mechanism 30 is used to transfer stainless steel products to the coarse grinding station 21A and the fine grinding station 41A. In some embodiments, the gripper mechanism 30 includes a movable arm 31 and a gripper assembly 32.

[0049] The movable arm 31 can be in the form of a robotic arm, and this embodiment does not limit it. The movable arm 31 is located on the machine base 10 and drives the gripper assembly 32 to move between the coarse grinding station 21A and the fine grinding station 41A.

[0050] The gripper assembly 32 includes an adsorption structure 321 and a fixing structure 322. The adsorption structure 321 is used to adsorb or release stainless steel products. For example, the adsorption structure 321 can adsorb stainless steel products located at the coarse grinding station 21A. Then, the moving arm 31 drives the gripper assembly 32 to move and move it above the fine grinding station 41A. At this time, the adsorption structure 321 can release the stainless steel products, so that the stainless steel products are placed on the fine grinding station 41A to realize the transfer of stainless steel products.

[0051] In this configuration, after the stainless steel product is released by the adsorption structure 321, the fixing structure 322 presses against the stainless steel product to keep it stationary. Specifically, after the stainless steel product is released by the adsorption structure 321 into either the coarse grinding station 21A or the fine grinding station 41A, the fixing structure 322 presses against the stainless steel product to keep it stationary in either station. Specifically, when the stainless steel product is released by the adsorption structure 321 into the coarse grinding station 21A, the fixing structure 322 presses against the stainless steel product to keep it stationary in the coarse grinding station 21A; similarly, when the stainless steel product is released by the adsorption structure 321 into the fine grinding station 41A, the fixing structure 322 presses against the stainless steel product to keep it stationary in the fine grinding station 41A. It should be noted that the moving arm 31 can directly move the adsorption structure 321 and the fixing structure 322 closer to or further away from the stainless steel product.

[0052] Thus, when grinding stainless steel products, for example, when the coarse grinding component 22 grinds the stainless steel products and the fine grinding component 42 grinds the stainless steel products, the fixing component can automatically press against the stainless steel products to prevent them from shifting. As a result, when the grinding operation is performed later, the stainless steel products will remain stationary and will not shift, thereby ensuring the precision of the grinding and ensuring the quality of the stainless steel products after grinding.

[0053] Please refer to the following: Figures 1-3In some embodiments, the fixed structure 322 includes a first driving member 3221 and a pressure head 3222. The first driving member 3221 can be a cylinder, and it is mounted on the moving arm 31. The pressure head 3222 is drive-connected to the first driving member 3221, meaning the pressure head 3222 is connected to the drive end of the first driving member 3221.

[0054] Driven by the first driving component 3221, the pressure head 3222 can move along the height direction to approach or move away from the stainless steel product, thereby pressing or releasing the stainless steel product. In this way, the pressure head 3222 can be automatically driven to press or release the stainless steel product directly through the first driving component 3221, and the driving method is simple and relatively precise.

[0055] Please refer to the following: Figures 1-3 In some embodiments, the pressure head 3222 includes a connecting portion 3222A and a pressing portion 3222B. The connecting portion 3222A is made of a rigid material, such as metal, and is fixedly connected to the first driving member 3221. The pressing portion 3222B is made of a flexible material, such as silicone, and is connected to the side of the connecting portion 3222A opposite to the first driving member 3221. This arrangement prevents the pressing portion 3222B from scratching or damaging the surface of the stainless steel product when pressing it.

[0056] Please refer to the following: Figures 1-3 In some embodiments, the adsorption structure 321 includes a second driving member 3211 and a suction cup 3212. The second driving member 3211 can be a cylinder, and the second driving member 3211 is mounted on the moving arm 31. The suction cup 3212 is throttle-connected to the second driving member 3211, that is, the suction cup 3212 is connected to the driving end of the second driving member 3211.

[0057] Driven by the second driving component 3211, the suction cup 3212 can move along the height direction to adsorb or release stainless steel products. Thus, the second driving component 3211 can directly and automatically drive the suction cup 3212 to adsorb or release stainless steel products, resulting in a simple and relatively precise driving method.

[0058] The suction cup 3212 can adsorb stainless steel products in the following ways: when the stainless steel product is light, after the suction cup 3212 presses against the stainless steel product, a negative pressure is generated between the suction cup 3212 and the stainless steel product, thereby adsorbing the stainless steel product; when the stainless steel product is heavy, a pump body can be provided. After the suction cup 3212 presses against the stainless steel product, the pump body will draw air to generate a negative pressure between the suction cup 3212 and the stainless steel product, thereby adsorbing the stainless steel product; this embodiment does not limit this.

[0059] Please refer to the following: Figures 1-3 Optionally, the adsorption structure 321 includes multiple structures arranged at intervals. These multiple adsorption structures 321 work together to adsorb stainless steel products. In this embodiment, the combined effect of the multiple adsorption structures 321 effectively enhances the adsorption effect on the stainless steel products, thereby effectively preventing the stainless steel products from accidentally falling during transport.

[0060] Please refer to the following: Figures 1-3 In some embodiments, the gripper assembly 32 further includes a connecting plate 323, a fixing structure 322, and multiple adsorption structures 321 spaced apart and connected to the connecting plate 323. In this way, the fixing structure 322 and the multiple adsorption structures 321 can be integrated and mounted on the connecting plate 323, allowing direct disassembly and assembly of the connecting plate 323 and the moving arm 31. This eliminates the need to individually install each fixing structure 322 and each adsorption structure 321 onto the moving arm 31, effectively improving the disassembly and assembly efficiency of the gripper mechanism 30.

[0061] Please refer to the following: Figures 1-3 In some embodiments, the movable arm 31 includes an arm body 311 and a mounting portion 312. The arm body 311 serves as the main body of the movable arm 31, is disposed on the machine base 10, and is movable relative to the machine base 10. The mounting portion 312 is connected to one end of the arm body 311 and extends along the height direction, and a connecting plate 323 is connected to the mounting portion 312.

[0062] The connecting plate 323 can be connected to different positions along the extension direction of the mounting portion 312 to adjust its own height position. In some exemplary structural forms, the mounting portion 312 is provided with multiple sets of connecting holes at intervals along its height direction. The mounting portion 312 can selectively connect to at least one set of connecting holes to adjust the installation position, thereby changing the height position of the connecting plate 323, and consequently changing the height position of the fixing structure 322 and the multiple adsorption structures 321.

[0063] In this embodiment, the connecting plate 323 can be adaptively adjusted to different positions on the mounting part 312 according to the actual height of the stainless steel product, thereby adjusting the height position of the fixing structure 322 and the multiple adsorption structures 321 to ensure that the fixing structure 322 can fix the stainless steel product and the multiple adsorption structures 321 can adsorb the stainless steel product.

[0064] Please refer to the following: Figures 1-3In some embodiments, both the movable arm 31 and the gripper assembly 32 include multiple movable arms 31, with the ends of the multiple movable arms 31 connected together, and one gripper assembly 32 is correspondingly mounted on one movable arm 31.

[0065] The gripper mechanism 30 also includes a drive structure 33, which can be a drive motor. This drive structure 33 is mounted on the machine base 10 and is connected to multiple moving arms 31 for transmission, driving the moving arms 31 to rotate relative to the machine base 10. This allows each gripper assembly 32 to move between different workstations, such as between the rough grinding workstation 21A and the fine grinding workstation 41A. In this way, the working efficiency of the edge grinding machine 100 can be greatly improved through the cooperation of multiple gripper assemblies 32.

[0066] Please refer to the following: Figures 1-3 Furthermore, the drive structure 33 includes a cam divider 331, which has an output shaft 3311. The output shaft 3311 is fixedly connected to a plurality of moving arms 31 so that the cam divider 331 can drive the plurality of moving arms 31 to rotate intermittently. Because the cam divider 331 has intermittent motion, it can convert continuous motion into precise intermittent motion.

[0067] For example, the edge grinding machine 100 further includes a loading mechanism and a unloading mechanism respectively provided on the machine base 10. The loading mechanism has a loading station, and the unloading mechanism has an unloading station. Specifically, during the process of the output shaft 3311 rotating one revolution (360 degrees), the output shaft 3311 can drive each moving arm 31 to complete multiple indexing processes of moving and stopping, so that the gripper assembly 32 can move between the loading station, the coarse grinding station 21A, the fine grinding station 41A, and the unloading station. That is, it can rotate 90 degrees and stop, then rotate another 90 degrees and stop again. In this way, when the moving arm 31 stops, the coarse grinding mechanism 20, the fine grinding mechanism 40, the fixed structure 322, and the adsorption structure 321 can all work.
