[0072] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments of the present application.

[0073] Please refer to Figures 1 to 2B , Figure 1 An embodiment of the present application provides a polishing system 100. The polishing system 100 is used for polishing an outer surface of a workpiece 11. Figure 2A and Figure 2B An embodiment of the present application provides a workpiece 11. The workpiece 11 to be polished can be a non-magnetic workpiece 11.

[0074] In the embodiments of the present application, the type of the workpiece 11 is not specifically limited. For example, the workpiece 11 can be a volume key of a smart phone or a tablet computer.

[0075] In the embodiments of the present application, a plurality of workpieces 11 arranged side by side can be fixedly connected with a connecting strip 12 to form an assembly 10. The workpiece 11 can include a connecting side 111 and a first machining side 112, and the connecting side 111 and the first machining side 112 are oppositely arranged. The first machining side 112 is a flat surface, and the connecting side 111 is an uneven surface. The first machining side 112 is a side of the workpiece 11 that needs to be polished.

[0076] It can be understood that the connecting strip 12 can be a strip-shaped component made of metal. In the embodiments of the present application, the material of the connecting strip 12 is not specifically limited.

[0077] In the embodiments of the present application, the way in which the polishing device 20 polishes the workpiece 11 is not specifically limited. For example, the polishing device 20 can polish the workpiece 11 by using a polishing piece such as sandpaper having a rough surface.

[0078] In the embodiments of the present application, the way in which the cleaning device 30 cleans the workpiece 11 is not specifically limited. For example, the cleaning device 30 can clean the workpiece 11 by means of liquid immersion, liquid spraying, blowing, etc.

[0079] Please refer to Figure 3 In some embodiments, the polishing system 100 can include a polishing device 20, a cleaning device 30, and a clamping jig 40. The polishing device 20 is used to polish the outer surface of the workpiece 11. The cleaning device 30 is used to clean the surface of the polished workpiece 11 to remove debris and / or stains from the outer surface of the polished workpiece 11. The clamping jig 40 is used to clamp and fix a plurality of assemblies 10.

[0080] Each assembly 10 can include a group of workpieces 11 and at least one connecting strip 12. A group of workpieces 11 can include a plurality of workpieces 11. In each group of workpieces 11, the plurality of workpieces 11 are arranged side by side. In each assembly 10, the connecting strip 12 is fixedly connected with the connecting sides 111 of the plurality of workpieces 11.

[0081] In the embodiments of the present application, the connecting strip 12 and the plurality of workpieces 11 are fixedly connected by welding. The connecting side 111 of the plurality of workpieces 11 can be a stepped surface, and the middle part of the connecting side 111 is a flat surface. When the plurality of workpieces 11 are arranged at intervals along the width direction, and the connecting sides 111 of the plurality of workpieces 11 all face the same direction, the connecting strip 12 can be welded and fixed with the middle part of the connecting side 111 of the plurality of workpieces 11 to obtain the assembly 10. In each assembly 10, the width direction of each workpiece 11 is the same as the length direction of the connecting strip 12.

[0082] In other embodiments, the connecting strips 12 can be fixedly connected to the plurality of workpieces 11 by other fixing connection manners. The other fixing connection manners can include adhesive fixing, buckle fixing, etc.

[0083] Please refer to Figure 4 In some embodiments, the clamping jig 40 can include a clamping base plate 41, a first pressing block 42, and a second pressing block 43.

[0084] The clamping base plate 41 can include a base portion 411, a first extending portion 412, and a plurality of second extending portions 413. The first extending portion 412 is protruded on one side of the base portion 411 in the height direction and fixedly connected to the base portion 411. The edge of the first extending portion 412 is spaced apart from the edge of the base portion 411. The plurality of second extending portions 413 are each protruded on a side of the first extending portion 412 away from the base portion 411 and fixedly connected to the first extending portion 412. The plurality of second extending portions 413 are spaced apart in the circumferential direction. Each two adjacent second extending portions 413 form a receiving space 44. Each receiving space 44 is used for receiving one connecting strip 12. Each second extending portion 413 is provided with a clamping limiting slot 45 on both sides close to the adjacent second extending portion 413. Each clamping limiting slot 45 is used for receiving at least part of the structure of one workpiece 11. Each clamping limiting slot 45 is in communication with the adjacent receiving space 44.

[0085] The clamping base plate 41 is provided with a clamping limiting slot 46. The first extending portion 412 is annular, and the hollow of the first extending portion 412 and the base portion 411 cooperatively form the clamping limiting slot 46. The first pressing block 42 is used for entering the clamping limiting slot 46 and pressing the first ends of the plurality of connecting strips 12. The second pressing block 43 is used for entering the space between the edge of the base portion 411 and the edge of the first extending portion 412 and pressing the second ends of the plurality of connecting strips 12.

[0086] In the embodiments of the present application, the width of the receiving space 44 is not specifically limited. For example, the width of the receiving space 44 can be equal to the width of the connecting strip 12, and the two side walls of the receiving space 44 can limit the movement of the connecting strip 12, i.e., limit the movement of the combined assembly 10, from the width direction of the connecting strip 12. For another example, the width of the receiving space 44 can be greater than the width of the connecting strip 12.

[0087] It can be understood that in the second extension part 413 located on both sides of each accommodation space 44, one second extension part 413 corresponds to the plurality of clamping limiting grooves 45 facing the accommodation space 44, and the other second extension part 413 corresponds to the plurality of clamping limiting grooves 45 facing the accommodation space 44, and each two corresponding clamping limiting grooves 45 form a set of clamping limiting grooves 45. In each two adjacent second extension parts 413, each set of corresponding clamping limiting grooves 45 can accommodate two ends of a workpiece 11 in the length direction. Each clamping limiting groove 45 is shaped to fit one end of the workpiece 11. In this way, each set of corresponding clamping limiting grooves 45 can achieve the limitation of the movement of a workpiece 11.

[0088] It can be understood that when the workpiece 11 is accommodated in the corresponding clamping limiting groove 45, the connecting side 111 abuts against the bottom wall of the clamping limiting groove 45, and the first machining side 112 extends out of the clamping limiting groove 45 from the opening of the clamping limiting groove 45.

[0089] It can be understood that the center of the clamping bottom plate 41 can be the center of the circle when the plurality of second extension parts 413 are arranged in the circumferential direction. When the plurality of connecting strips 12 are located in the corresponding accommodation spaces 44, and the plurality of workpieces 11 are located in the corresponding clamping limiting grooves 45, the placement of the plurality of assemblies 10 on the clamping jig 40 is achieved. At this time, the first end of the plurality of connecting strips 12 is arranged towards the center of the clamping bottom plate 41, and the second end of the plurality of connecting strips 12 is arranged towards the edge of the clamping bottom plate 41. The first end of each connecting strip 12 is the first end of the corresponding assembly 10, and the second end of each connecting strip 12 is the second end of the corresponding assembly 10.

[0090] In the embodiments of the present application, the shape of the clamping jig 40 is not specifically limited. For example, the cross section of the base part 411 is circular, the cross section of the first extension part 412 is annular, and the cross section of each second extension part 413 is fan-shaped. The base part 411 is coaxial with the first extension part 412, and the plurality of second extension parts 413 are arranged in a direction surrounding the base part 411. The diameter of the base part 411 is greater than the diameter of the first extension part 412. When the plurality of connecting strips 12 are accommodated in the corresponding accommodation spaces 44, the length direction of each connecting strip 12 is the same as the direction of the diameters of the base part 411 and the first extension part 412.

[0091] It can be understood that when the first ends of the plurality of assemblies 10 are pressed by the first pressing block 42 and the second ends are pressed by the second pressing block 43, the first pressing block 42 cooperates with the clamping bottom plate 41 to achieve clamping and fixing of the first ends of the plurality of assemblies 10, and the second pressing block 43 cooperates with the clamping bottom plate 41 to achieve clamping and fixing of the second ends of the plurality of assemblies 10. Thus, after the first pressing block 42 is fixedly connected with the clamping bottom plate 41 and the second pressing block 43 is fixedly connected with the clamping bottom plate 41, the movement of each assembly 10 is limited by the first pressing block 42, the second pressing block 43, the corresponding receiving space 44, and the corresponding clamping limiting groove 45, thereby achieving fixing of the plurality of assemblies 10.

[0092] It can be understood that the first pressing block 42 and the second pressing block 43 are detachably connected to the clamping bottom plate 41. In the embodiments of the present application, the detachable connection manner is not specifically limited. For example, the detachable connection manner can include, but is not limited to, screw fixing, adhesive fixing, buckle fixing, etc.

[0093] In the embodiments of the present application, the clamping jig 40 fixes the two ends of the connecting strip 12 in the assembly 10 to achieve fixing of the plurality of workpieces 11 on the clamping jig 40. Thus, the plurality of workpieces 11 can be fixedly arranged on the clamping jig 40 without adhesion, which reduces the probability of the plurality of workpieces 11 falling off from the clamping jig 40 and improves the appearance qualification rate of the workpieces 11 after polishing. Meanwhile, the plurality of workpieces 11 are not pressed by the first pressing block 42 and the second pressing block 43, which reduces the situation that one end of the workpiece 11 is raised due to different pressures on the two ends, reduces the situation that the polishing depth is different at different positions on the first machining side 112 of the workpiece 11, and improves the size qualification rate of the workpiece 11 after polishing.

[0094] Please refer to Figure 5 In some embodiments, the first pressing block 42 can include a first body 421 fixedly connected and a first protruding edge 422 protruding from a peripheral wall of the first body 421 and located on a side of the first pressing block 42 away from the clamping bottom plate 41 in the height direction of the first pressing block 42. The first body 421 is used to enter the clamping limiting groove 46. When the first body 421 enters the clamping limiting groove 46, the first protruding edge 422 can abut against the first ends of the plurality of assemblies 10 to achieve clamping and fixing of the first ends of the plurality of assemblies 10.

[0095] In the embodiments of the present application, the shape of the first pressing block 42 is not specifically limited. For example, the first body 421 is in a cylindrical shape, and the first protruding edge 422 is in a circular ring shape.

[0096] In some embodiments, the second pressing block 43 can include a second main body 431 and a second protruding rim 432 fixedly connected. The second main body 431 is annular. The second protruding rim 432 is protruded inwardly from the second main body 431 and located on the side of the second pressing block 43 away from the clamping base plate 41 in the height direction of the second pressing block 43. The second main body 431 is used to enter the spacing space between the edge of the first extending portion 412 and the edge of the clamping base plate 41. When the second main body 431 enters the spacing space between the edge of the first extending portion 412 and the edge of the clamping base plate 41, the second protruding rim 432 can abut against the second end of the plurality of assembled components 10 to achieve clamping and fixing of the second end of the plurality of assembled components 10.

[0097] In the embodiments of the present application, the shape of the second pressing block 43 is not specifically limited. For example, the second main body 431 is circular annular, and the second protruding rim 432 is circular annular.

[0098] It can be understood that after the plurality of assembled components 10 are fixed on the clamping jig 40, the polishing device 20 can polish the first machining surface of the plurality of assembled components 10. After polishing, the worker can disassemble the first pressing block 42 and the second pressing block 43 from the clamping base plate 41, and disassemble the plurality of assembled components 10 from the clamping base plate 41. Then, the worker can clean the plurality of assembled components 10 by the cleaning device 30 to clean the debris and / or stains attached to the assembled components 10.

[0099] It can be understood that after the plurality of assembled components 10 are cleaned, the worker can detect whether there is damage on the outer surface of the plurality of assembled components 10 by visual observation or with the assistance of a detection device, then disassemble the assembled components 10 found no damage, and collect the plurality of workpieces 11 disassembled, to end the process of polishing and machining the workpieces 11.

[0100] In some embodiments, a plurality of first positioning pins 47 are protruded on the first extending portion 412. Among them, part of the first positioning pins 47 are located close to the clamping positioning groove 46 and are arranged at intervals in the circumferential direction; the remaining first positioning pins 47 are located close to the edge of the first extending portion 412 and are arranged at intervals in the circumferential direction. Each first positioning pin 47 is correspondingly arranged with a receiving space 44, and each receiving space 44 is correspondingly arranged with a first positioning pin 47 at the first end and another first positioning pin 47 at the second end.

[0101] A plurality of positioning holes 121 are formed on each connecting strip 12. The plurality of positioning holes 121 can be respectively located at both ends of the connecting strip 12 in the length direction. When the plurality of assembled components 10 are placed on the clamping jig 40, each first positioning pin 47 is used to pass through a positioning hole 121.

[0102] It can be understood that when the plurality of positioning holes 121 on the assembly 10 are respectively aligned with the corresponding first positioning pins 47, the connecting strip 12 in the assembly 10 is aligned with the receiving space 44, and the plurality of workpieces 11 in the assembly 10 are aligned with the plurality of clamping limiting grooves 45. Before placing the assembly 10 on the clamping jig 40, the worker can first realize the pre-positioning of the assembly 10 in the clamping jig 40 by aligning the positioning holes 121 with the first positioning pins 47. When the assembly 10 is placed in the clamping jig 40, the first positioning pins 47 are inserted into the corresponding positioning holes 121, which limits the movement of the assembly 10 in the direction perpendicular to the length direction of the first positioning pins 47, thereby reducing the possibility of the assembly 10 falling off the clamping jig 40 when the first pressing block 42 and the second pressing block 43 are not in contact with the assembly 10. In this way, the arrangement of the plurality of first positioning pins 47 can improve the stability of the assembly 10 assembled on the clamping fixture.

[0103] Please refer to Figures 6 to 8 In some embodiments, the polishing system 100 can further include a welding jig 50. The welding jig 50 can include a first cover 51 and a second cover 52. The first cover 51 and the second cover 52 are detachably connected.

[0104] The first cover 51 is hollow. The first cover 51 is provided with a first positioning groove 511 on the inner wall of one side in the height direction, and the first positioning groove 511 is used for accommodating the connecting strip 12. The first positioning groove 511 is arranged in the middle of the side wall of the first cover 51 in the height direction. The side wall of the first cover 51 in the height direction is also provided with a plurality of second positioning grooves 512, and the plurality of second positioning grooves 512 are arranged in the length direction of the first cover 51. Each second positioning groove 512 is adapted to the shape of the workpiece 11. Each second positioning groove 512 is in communication with the first positioning groove 511. In the width direction of the first cover 51, the width of each second positioning groove 512 is greater than the width of the first positioning groove 511. Each second positioning groove 512 penetrates the first cover 51.

[0105] A plurality of second positioning pins 513 are arranged in the first positioning groove 511. The plurality of second positioning pins 513 are arranged in the length direction of the first cover 51, and each second positioning pin 513 is fixedly connected with the first cover 51. Each second positioning pin 513 is used for penetrating a positioning hole 121 on the connecting strip 12 to limit the movement of the connecting strip 12 in the first positioning groove 511.

[0106] It is understood that the welding fixture 50 is used to restrict the position of the connecting strip 12 and the multiple workpieces 11 during welding and fixing. Before fixing the connecting strip 12 and the multiple workpieces 11, the operator first aligns the positioning hole 121 with the corresponding second positioning pin 513 to determine the placement position of the connecting strip 12 in the first positioning groove 511; then, the second positioning pin 513 is passed through the corresponding positioning hole 121, allowing the connecting strip 12 to enter the first positioning groove 511. After the connecting strip 12 enters the first positioning groove 511 and abuts against the inner wall of the first positioning groove 511, the connecting strip 12 partially blocks the space of the multiple second positioning grooves 512.

[0107] Then, the workers place multiple workpieces 11 into their corresponding second positioning grooves 512, ensuring that the connecting side 111 of each workpiece 11 abuts against the connecting strip 12. At this point, a portion of the structure of each workpiece 11 is located within the second positioning groove 512, while the remaining structure protrudes from the second positioning groove 512 along the height direction of the workpiece 11. The connecting strip 12 abuts against the multiple workpieces 11 and prevents the multiple workpieces 11 from moving along the direction of the second positioning groove 512 through the first cover 51, thereby keeping the multiple workpieces 11 in their corresponding second positioning grooves 512 while preventing the multiple workpieces 11 from moving out of the first cover 51 through the second positioning groove 512.

[0108] It is understood that when multiple workpieces 11 are all located in their corresponding second positioning grooves 512, and multiple connecting sides 111 abut against the connecting strip 12, the operator can fasten the second cover 52 onto the first cover 51, thus achieving a fixed connection between the first cover 51 and the second cover 52. At this time, the second cover 52 abuts against the first processing side 112 of each workpiece 11. The second cover 52 and the connecting strip 12 cooperate to clamp and fix the multiple workpieces 11, and the multiple second positioning grooves 512 restrict the movement of the multiple workpieces 11 in the length and width directions, thereby fixing the multiple workpieces 11 within the welding fixture 50.

[0109] Then, the workers can flip the welding fixture 50 to expose the multiple second positioning grooves 512 through which the first cover 51 is inserted, and observe the position where the connecting strip 12 abuts against the multiple connecting sides 111 through the multiple second positioning grooves 512, and weld and fix the position where the connecting strip 12 abuts against the multiple connecting sides 111.

[0110] Understandably, workers can place multiple workpieces 11 and connecting strips 12 on welding fixture 50 for fixation, and then weld the connecting strips 12 and multiple workpieces 11 to obtain assembly 10. After obtaining multiple assemblies 10, workers can fix the multiple assemblies 10 on clamping fixture 40, and then use grinding equipment 20 to grind the multiple workpieces 11 in the multiple assemblies 10 on clamping fixture 40.

[0111] In the embodiments of this application, the method of detachable connection between the first cover 51 and the second cover 52 is not specifically limited. For example, the first cover 51 and the second cover 52 can be detachably connected by magnetic attraction.

[0112] For example, a plurality of first adsorption members 514 are provided in the first cover 51, the plurality of first adsorption members 514 are spaced apart, and each is fixedly connected to the inner wall of one side of the first cover 51 in the height direction. A plurality of protrusions 521 are provided on the second cover 52. The plurality of protrusions 521 are spaced apart. The plurality of protrusions 521 are used to extend into the first cover 51 when the second cover 52 is fastened to the first cover 51. A plurality of second adsorption members 522 are fixedly connected to each protrusion 521. The plurality of second adsorption members 522 correspond one-to-one with the plurality of first adsorption members 514. Each first adsorption member 514 is used to adsorb the corresponding second adsorption member 522 by magnetic adsorption, so as to achieve a fixed connection between the first cover 51 and the second cover 52.

[0113] In some cases, both the first adsorption element 514 and the second adsorption element 522 are magnets. Furthermore, the magnetic pole of the first adsorption element 514 facing the second adsorption element 522 is opposite to the magnetic pole of the second adsorption element 522 facing the first adsorption element 514.

[0114] In other cases, one of the first adsorption element 514 and the second adsorption element 522 is a magnet, and the other is a ferromagnetic element made of a ferromagnetic material. In the embodiments of this application, the ferromagnetic material is not specifically limited. For example, the ferromagnetic material may include, but is not limited to, iron alloys.

[0115] Please refer to the following: Figure 9A and Figure 9B In some embodiments, the workpiece 11 further includes a second processing side 113 and a third processing side 114. The second processing side 113 and the third processing side 114 are disposed opposite to each other. Both the second processing side 113 and the third processing side 114 need to be ground, and both the second processing side 113 and the third processing side 114 are planar. The grinding system 100 may also include an adhesive fixture 60. The adhesive fixture 60 may include an adhesive base plate 61, a double-sided adhesive layer 62, and a limiting plate 63.

[0116] The bonding base plate 61 and the limiting plate 63 are spaced apart along the height direction. A double-sided adhesive layer 62 is located between the bonding base plate 61 and the limiting plate 63 and is fixedly connected to both. The double-sided adhesive layer 62 can be a substrate-based double-sided adhesive. Multiple bonding limiting grooves 631 are provided on the limiting plate 63. Each bonding limiting groove 631 penetrates the limiting plate 63 along its height direction. Each bonding limiting groove 631 is adapted to the shape of the workpiece 11. Each bonding limiting groove 631 is used to accommodate one workpiece 11. The workpiece 11 can be moved into the bonding limiting groove 631 with its second processing side 113 facing the double-sided adhesive layer 62, or with its third processing side 114 facing the double-sided adhesive layer 62. When the workpiece 11 is located in the bonding limiting groove 631, the third processing side 114 or the second processing side 113 of the workpiece 11 is bonded and fixed to the double-sided adhesive layer 62, thereby realizing the fixed connection of the workpiece 11 on the bonding fixture 60.

[0117] In the embodiments of this application, the layout of the multiple adhesive limiting grooves 631 is not specifically limited. For example, the limiting disk 63 is a disk, and multiple sets of adhesive limiting grooves 631 are arranged at intervals along the direction surrounding the limiting disk 63. Each set of adhesive limiting grooves 631 includes multiple adhesive limiting grooves 631, and the multiple adhesive limiting grooves 631 in each set of adhesive limiting grooves 631 are arranged at intervals along the direction where the diameter of the limiting disk 63 is located.

[0118] It is understandable that before welding and fixing the connecting strip 12 to the multiple workpieces 11, the operator can first fix the workpieces 11 onto the bonding fixture 60, and use the grinding equipment 20 to grind one side of the second processing side 113 and the third processing side 114 of the multiple workpieces 11. Then, the multiple workpieces 11 can be removed from the bonding fixture 60 and cleaned using the cleaning equipment 30. Then, the operator can fix the multiple workpieces 11 onto another clean bonding fixture 60, and use the grinding equipment 20 to grind the other side of the second processing side 113 and the third processing side 114 of the multiple workpieces 11. Then, the multiple workpieces 11 can be removed from the bonding fixture 60 and cleaned using the cleaning equipment 30.

[0119] Once the second processing side 113 and the third processing side 114 of each workpiece 11 have been ground and cleaned, the workers can then use the welding fixture 50 to weld and fix the connecting strip 12 and multiple workpieces 11.

[0120] It is understood that the adhesive base plate 61 can be fixedly connected to the limiting plate 63 through the double-sided adhesive layer 62, or it can be fixedly connected to the limiting plate 63 through other connecting parts. The embodiments of this application do not limit this. For example, after the limiting plate 63 is fixedly bonded to the adhesive base plate 61 through the double-sided adhesive layer 62, the worker can further fix the limiting plate 63 and the adhesive base plate 61 together with screws.

[0121] It is understood that both the second processing side 113 and the third processing side 114 are planar, and therefore can be fixedly connected to the bonding fixture 60 by adhesive bonding. Compared with the use of hot wax or glue to bond the workpiece 11 in related technologies, using a double-sided adhesive layer 62 to bond the workpiece 11 can reduce the amount of adhesive residue on the workpiece 11 after it is removed from the bonding fixture 60, and improve the adhesion strength, making the adhesive residue on the workpiece 11 easier to clean. This reduces the probability of damaging the appearance of the workpiece 11 during cleaning and improves the appearance qualification rate of the workpiece 11.

[0122] In the embodiments of this application, the double-sided adhesive layer 62 is a substrate-based double-sided adhesive. The substrate in the substrate-based double-sided adhesive can improve the structural strength of the double-sided adhesive layer 62. When the grinding equipment 20 grinds multiple second processing sides 113 or multiple third processing sides 114, the grinding equipment 20 abuts against and presses the multiple workpieces 11. At this time, the substrate in the double-sided adhesive layer 62 can support the multiple workpieces 11, reduce the degree of deformation of the double-sided adhesive layer 62, and thus reduce the possibility of insufficient grinding depth of the second processing side 113 or third processing side 114 due to the deformation of the double-sided adhesive layer 62. This can improve the dimensional qualification rate of the workpieces 11 after grinding.

[0123] Meanwhile, when the double-sided adhesive layer 62 is connected to the second processed side 113 or the third processed side 114 that has been sanded, the double-sided adhesive layer 62 can be attached to the second processed side 113 or the third processed side 114 to protect the appearance of the sanded second processed side 113 or the third processed side 114 and reduce the damage to the second processed side 113 or the third processed side 114 due to direct collision with the adhesive base plate 61.

[0124] Using the grinding system 100 provided in the embodiments of this application, the operator can first fix multiple workpieces 11 using the bonding fixture 60, and then grind the second processing side 113 and the third processing side 114 of the workpieces 11 respectively. Then, the operator can place the connecting strip 12 and the multiple workpieces 11 in the welding fixture 50, and use the welding fixture 50 to fix the connecting strip 12 and the multiple workpieces 11 relatively, and then weld the connecting strip 12 and the multiple workpieces 11 together to obtain the assembly 10. The operator can then fix the multiple assemblies 10 in the clamping fixture 40 and grind the first processing side 112 of the multiple workpieces 11 to complete the grinding of all the positions on the workpieces 11 that need grinding. After grinding each side, the multiple workpieces 11 need to be cleaned using the cleaning equipment 30 to remove debris and / or adhesive substances from the workpieces 11.

[0125] Thus, when workpiece 11 has an uneven surface, the operator can weld the uneven surface to the connecting strip 12, and then restrict the movement of multiple workpieces 11 by limiting the movement of the connecting strip 12. By welding and fixing the connecting strip 12 to multiple workpieces 11, and by clamping and fixing the connecting strip 12 with the clamping fixture 40, the probability of workpiece 11 falling off the clamping fixture 40 during the grinding process can be reduced, thereby reducing the probability of damage to the appearance of workpiece 11 and improving the appearance qualification rate of workpiece 11 after grinding.

[0126] Please see Figure 10 , Figure 10 An embodiment of this application illustrates a grinding method. The grinding method is used to grind the outer surface of a workpiece 11. The grinding method can be applied to a grinding system 100.

[0127] Step S101: Place multiple workpieces 11 in the corresponding bonding limiting grooves 631 in the bonding fixture 60, so that multiple third processing sides 114 are bonded and fixed to the double-sided adhesive layer 62.

[0128] Step S102: Grind multiple second processing sides 113 using grinding equipment 20.

[0129] Step S103: Remove the multiple workpieces 11 from the bonding fixture 60.

[0130] Step S104: Clean the multiple workpieces 11 using the cleaning equipment 30.

[0131] Step S105: Place multiple workpieces 11 in the corresponding bonding limiting grooves 631 in another bonding fixture 60, so that multiple second processing sides 113 are bonded and fixed to the double-sided adhesive layer 62.

[0132] Step S106: Grind multiple third processing sides 114 using grinding equipment 20.

[0133] Step S107: Remove the multiple workpieces 11 from the bonding fixture 60.

[0134] Step S108: Clean the multiple workpieces 11 using the cleaning equipment 30.

[0135] Step S109: Assemble the connecting side 111 of the multiple sets of workpieces 11 with the corresponding connecting strip 12.

[0136] It is understood that in each group of workpieces 11, multiple workpieces 11 are spaced apart along the width direction. A group of workpieces 11 and at least one connecting strip 12 can form an assembly 10. In each assembly 10, the width direction of the workpieces 11 is consistent with the length direction of the connecting strip 12.

[0137] Step S1010: Clamp and fix the connecting strip 12 of the multiple assemblies 10 onto the clamping fixture 40.

[0138] Step S1011: Grind the first machining side 112 on the multiple assemblies 10 using the grinding equipment 20.

[0139] Step S1012: Remove the multiple assemblies 10 from the clamping fixture 40.

[0140] Step S1013: Clean the multiple assemblies 10 using the cleaning equipment 30.

[0141] It is understandable that after cleaning the multiple assemblies 10, the workers can disassemble the multiple assemblies 10 to obtain multiple connecting strips 12 and multiple sets of workpieces 11, and then perform appearance inspection on the multiple sets of workpieces 11.

[0142] In this embodiment, steps S101 to S104 are executed before step S105. In other embodiments, steps S101 to S105 may be executed after step S108.

[0143] Please refer to the following: Figure 11 In some embodiments, each workpiece 11 further includes multiple chamfered ends, each chamfered end being an arc surface. Specifically, a chamfered end is formed between the first end of the second processing side 113 and the first end of the third processing side 114, and the connection is achieved through this chamfered end; a chamfered end is also formed between the second end of the second processing side 113 and the second end of the third processing side 114, and the connection is achieved through this chamfered end.

[0144] After steps S101 to S108 are completed, the polishing method may further include:

[0145] Step S111: Manually grind the chamfered ends of multiple workpieces 11.

[0146] Step S112: Clean the multiple workpieces 11 using the cleaning equipment 30.

[0147] It is understandable that when grinding the chamfered ends of curved surfaces, manual grinding can improve the grinding accuracy. After grinding the chamfered ends of multiple workpieces 11 and cleaning the multiple workpieces 11, step S109 can be performed.

[0148] Please see Figure 12 In some embodiments, assembling each set of workpieces 11 with the corresponding connecting strip 12 to form the assembly 10 may include steps S121 to S125. It is understood that the assembly of each set of workpieces 11 with the corresponding connecting strip 12 can be achieved by using a welding fixture 50, and steps S121 to S125 can be sub-steps of step S109.

[0149] Step S121: Align the multiple positioning holes 121 of the connecting strip 12 with the corresponding second positioning pins 513 in the first cover 51.

[0150] Step S122: Move the connecting strip 12 so that the multiple second positioning pins 513 pass through the corresponding positioning holes 121 and the connecting strip 12 enters the first positioning groove 511.

[0151] Step S123: Place multiple workpieces 11 into the corresponding second positioning slots 512.

[0152] It is understood that when the workpiece 11 is placed in the second positioning groove 512, the connecting strip 12 abuts against the connecting side 111 of the workpiece 11 and blocks the workpiece 11 to prevent the workpiece 11 from moving out of the second positioning groove 512 along the direction through the first cover 51.

[0153] Step S124: Attach the second cover 52 to the first cover 51 to fix the first cover 51 and the second cover 52.

[0154] It is understood that the first cover 51 and the second cover 52 are detachably fixedly connected. When the first cover 51 and the second cover 52 are fixed, the second cover 52 abuts against the first processing side 112 of the plurality of workpieces 11, thereby cooperating with the connecting strip 12 to clamp and fix the plurality of workpieces 11. At the same time, each second positioning groove 512 restricts the movement of the workpiece 11 in the length and width directions of the workpiece 11. Therefore, when the first cover 51 and the second cover 52 are fixedly connected, the plurality of workpieces 11 are fixed in the welding fixture 50.

[0155] Step S125: Weld multiple connecting sides 111 onto the connecting strip 12 through multiple second positioning holes 121.

[0156] It is understood that the connecting sides 111 and connecting strips 12 of the multiple workpieces 11 can be exposed from the corresponding second positioning holes 121. The operator can weld the multiple connecting sides 111 and connecting strips 12 at the positions where they abut against each other to obtain the assembly 10.

[0157] It is understandable that after the worker performs steps S121 to S125 on a set of workpieces 11 and corresponding connecting strips 12, the first cover 51 and the second cover 52 can be separated, and the resulting assembly 10 can be taken out from the first cover 51. After steps S121 to S125 are performed multiple times, multiple assemblies 10 can be obtained, and the process can proceed to step S1010.

[0158] Please see Figure 13 In some embodiments, the method of clamping and fixing the connecting strips 12 of the multiple assemblies 10 to the clamping fixture 40 may include steps S131 to S135. Steps S131 to S135 may be sub-steps of step S1010.

[0159] Step S131: Place multiple assemblies 10 on the clamping fixture 40.

[0160] The method of placing multiple assemblies 10 on the clamping fixture 40 may include: aligning multiple positioning holes 121 on each assembly 10 with corresponding first positioning pins 47, and aligning multiple workpieces 11 with corresponding clamping limiting grooves 45; then bringing the assembly 10 close to the clamping base plate 41, so that multiple first positioning pins 47 pass through the corresponding positioning holes 121, and so that multiple workpieces 11 enter the corresponding clamping limiting grooves 45.

[0161] It is understood that when multiple first positioning pins 47 pass through corresponding positioning holes 121 and multiple clamping and limiting grooves 45 accommodate corresponding workpieces 11, the clamping fixture 40 can restrict the movement of multiple assemblies 10 from the length direction of the connecting strip 12 (i.e. the width direction of the workpiece 11) and the width direction of the connecting strip 12 (i.e. the length direction of the workpiece 11).

[0162] Step S132: Press the first pressure block 42 onto the first end of the plurality of assemblies 10.

[0163] It can be understood that the first end of each assembly 10 is the first end of the connecting strip 12 in that assembly 10. When the worker puts the first pressure block 42 into the clamping and fixing slot 46, the first protruding edge 422 can abut against the first ends of the multiple assemblies 10 and cooperate with the clamping base plate 41 to clamp and fix the first ends of the multiple assemblies 10.

[0164] Step S133: Press the second pressure block 43 onto the second end of the plurality of connecting strips 12.

[0165] It can be understood that the second end of each assembly 10 is the second end of the connecting strip 12 in that assembly 10. When the worker places the second pressing block 43 into the space between the edge of the base 411 and the edge of the first extension 412, the second protruding edge 432 can abut against the second ends of the multiple assemblies 10 and cooperate with the clamping base plate 41 to clamp and fix the second ends of the multiple assemblies 10.

[0166] Step S134: Fix the first pressure block 42 and the second pressure block 43 onto the clamping base plate 41.

[0167] It is understandable that workers can fix the first pressure block 42 and the second pressure block 43 to the clamping base plate 41 in a detachable manner to fix multiple assemblies 10 in the clamping fixture 40.

[0168] The beneficial effects of the polishing method provided by the embodiments of this application, and Figures 1 to 9B The beneficial effects of the polishing system 100 shown are the same, and will not be repeated here.

[0169] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments described above should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application.
