[0002] With the development of technology, smartphones are becoming increasingly popular. To enhance the aesthetics of mobile phones, a 3D glass cover is often installed on the side with the screen. When manufacturing a 3D glass cover, the glass sheet is usually first placed in a heat bending machine to bend it into a 3D glass cover. Then, a polishing machine is used to polish the convex surface (front side) of the 3D glass cover to ensure the aesthetics of the 3D glass cover.

[0024] Please refer to Figures 1 to 5 An embodiment of the present invention provides a positioning mechanism, which includes a bracket 10, a positioning plate 20, a positioning assembly 30, a first driving assembly and a second driving assembly.

[0025] The positioning plate 20 is mounted on the top of the bracket 10 via a mounting block 11. There are two mounting blocks 11. Specifically, the top of the bracket 10 is provided with two mounting blocks 11 that are opposite to each other on the left and right sides, and the positioning plate 20 is mounted on top of the two mounting blocks 11. The mounting blocks 11 provide mounting support for the positioning plate 20.

[0026] The positioning assembly 30 includes a rectangular positioning platform 31 , a first positioning member 32 , a second positioning member 33 , a first positioning block 34 and a second positioning block 35 .

[0027] The positioning platform 31 is provided at the top of the positioning plate 20. The positioning platform 31 and the positioning plate 20 are preferably integrally formed. The first positioning member 32 is provided at one end of the positioning platform 31, for example, the right end, and the top of the first positioning member 32 is located above the positioning platform 31, and the bottom end of the first positioning member 32 is fixed to the top of the positioning plate 20. The top of the positioning platform 31 is provided with a through hole 311 corresponding to the first positioning member 32 at a position close to the other end of the positioning platform 31, for example, the left end, and the through hole 311 extends to the positioning plate 20. The first positioning block 34 is provided through the through hole 311 and the top of the first positioning block 34 is located above the positioning platform 31. The first positioning block 34 and the first positioning member 32 are arranged opposite to each other on the left and right. The second positioning member 33 is provided at one side of the positioning platform 31, for example, the rear side, and the top of the second positioning member 33 is located above the positioning platform 31, and the bottom end of the second positioning member 33 is fixed to the top of the positioning plate 20. The other side of the positioning platform 31, for example the front side, is provided with a notch 312 corresponding to the second positioning member 33, and the notch 312 extends to the positioning plate 20. The second positioning block 35 is arranged to pass through the notch 312, and the top of the second positioning block 35 is located above the positioning platform 31. The second positioning block 35 and the second positioning member 33 are arranged relative to each other in the front and back. A placement space for the 3D glass cover 100 is formed between the top of the positioning platform 31, the first positioning member 32, the second positioning member 33, the first positioning block 34, and the second positioning block 35. In actual application, after the 3D glass cover 100 is placed in the placement space, the top of the first positioning member 32, the top of the second positioning member 33, the top of the first positioning block 34, and the top of the second positioning block 35 are all located above the 3D glass cover 100.

[0028] The first positioning member 32 includes a plurality of first positioning posts 321 spaced apart along the width of the positioning platform 31. The top ends of the first positioning posts 321 are positioned above the positioning platform 31, and the bottom ends of the first positioning posts 321 are fixed to the top end of the positioning plate 20. The second positioning member 33 includes a plurality of second positioning posts 331 spaced apart along the length of the positioning platform 31. The top ends of the second positioning posts 331 are positioned above the positioning platform 31, and the bottom ends of the second positioning posts 331 are fixed to the top end of the positioning plate 20. In this embodiment, there are two first positioning posts 321 and two second positioning posts 331. It is understood that the number of first positioning posts 321 and second positioning posts 331 can be adjusted according to actual conditions.

[0029] The bottom ends of the first positioning block 34 and the second positioning block 35 are both located below the positioning plate 20. The bottom end of the first positioning block 34 is connected to the first driving assembly, which is used to drive the first positioning block 34 to move toward or away from the first positioning member 32. The bottom end of the second positioning block 35 is connected to the second driving assembly, which is used to drive the second positioning block 35 to move toward or away from the second positioning member 33.

[0030] With the above structure, in actual use, the 3D glass cover plate 100 is first placed in the placement space, with one side of the 3D glass cover plate 100 close to the first positioning block 34, the other side of the 3D glass cover plate 100 close to the first positioning member 32, one end of the 3D glass cover plate 100 close to the second positioning block 35, and the other end of the 3D glass cover plate 100 close to the second positioning member 33, with the front of the 3D glass cover plate 100 facing upward. Then, the first positioning block 34 is driven by the first driving assembly to move toward the first positioning member 32. During the movement of the first positioning block 34, when the first positioning block 34 contacts one side of the 3D glass cover plate 100, as the first positioning block 34 continues to move, the first positioning block 34 pushes the 3D glass cover plate 100 toward the first positioning member 32 until the other side of the 3D glass cover plate 100 abuts against the two first positioning posts 321 of the first positioning member 32. Then, the second driving assembly drives the second positioning block 35 to move toward the direction close to the second positioning member 33. During the movement of the second positioning block 35, when the second positioning block 35 contacts one end of the 3D glass cover 100, as the second positioning block 35 continues to move, the second positioning block 35 will push the 3D glass cover 100 toward the direction close to the second positioning member 33 until the other end of the 3D glass cover 100 abuts against the two second positioning posts 331 of the second positioning member 33, thereby achieving the positioning of the 3D glass cover 100. Figure 1 As shown, the 3D glass cover plate 100 can then be sucked by the loading and unloading mechanism of the polishing machine.

[0031] The present invention can position the 3D glass cover plate 100 with high precision through the arrangement of the bracket 10, the positioning plate 20, the positioning assembly 30, the first drive assembly and the second drive assembly, thereby ensuring that the position of the 3D glass cover plate 100 is accurate, so that the loading and unloading mechanism of the polishing machine can smoothly absorb the 3D glass cover plate 100, thereby improving production efficiency.

[0032] In this embodiment, a first buffer pad 341 is provided on one side of the first positioning block 34 near the first positioning member 32. The first buffer pad 341 is located above the positioning platform 31. When the first positioning block 34 contacts one side of the 3D glass cover 100, the first buffer pad 341 provides a buffering effect to prevent damage to the 3D glass cover.

[0033] A second buffer pad 351 is provided on the side of the second positioning block 35 near the second positioning member 33. The second buffer pad 351 is located above the positioning platform 31. When the second positioning block 35 contacts one end of the 3D glass cover 100, the second buffer pad 351 provides a cushioning effect, preventing damage to the 3D glass cover 100. There are two first buffer pads 341 and two second buffer pads 351, respectively. The two first buffer pads 341 are spaced apart along the width of the positioning platform 31, and the two second buffer pads 351 are spaced apart along the length of the positioning platform 31. The first buffer pads 341 and the second buffer pads 351 are both made of plastic. The cross-sectional shapes of the first buffer pads 341 and the second buffer pads 351 can be circular, rectangular, or the like.

[0034] A stopper 342 is provided on the side of the first positioning block 34 away from the first positioning member 32. The stopper 342 is located within the through hole 311, and a portion of the stopper 342 protrudes from the top of the positioning platform 31. As the first positioning block 34 moves away from the first positioning member 32, the stopper 342 limits its movement, preventing damage to the first positioning block 34.

[0035] In this embodiment, there are multiple positioning assemblies 30, which are divided into two positioning groups. The two positioning groups are symmetrically arranged along the width direction of the positioning plate 20. The positioning assemblies 30 of each positioning group are spaced apart along the length direction of the positioning plate 20. In this embodiment, each positioning group has four positioning assemblies 30, for example, so that the present invention can position eight 3D glass cover plates 100 at a time, thereby improving production efficiency. It is understandable that the number of positioning assemblies 30 in each positioning group can also be other, such as one, two, three, five, etc., which can be set according to actual conditions.

[0036] The first drive assembly includes a first drive member 50, which is arranged at the top of the bracket 10 and below the positioning plate 20. The first drive member 50 is located between the two mounting blocks 11. A first connecting plate 51 is provided above the first drive member 50. One end of the first connecting plate 51 is connected to the output end of the first drive member 50 via a first connecting block 511. A second connecting plate 52 is provided at the top of the first connecting plate 51. Two third connecting plates 53 are provided at each end of the second connecting plate 52. The two third connecting plates 53 are both located below the positioning plate 20 and correspond to the two positioning groups respectively. The two third connecting plates 53, the first connecting plate 51 and the second connecting plate 52 are all located between the two mounting blocks 11. The bottom end of the first positioning block 34 of the positioning assembly 30 of one positioning group is both located at the top of one of the third connecting plates 53, and the bottom end of the first positioning block 34 of the positioning assembly 30 of the other positioning group is both located at the top of the other third connecting plate 53. The first driving member 50 is used to drive the first connecting plate 51, the second connecting plate 52 and the two third connecting plates 53 to move left and right, so that the two third connecting plates 53 can respectively drive the first positioning block 34 of the corresponding positioning assembly 30 to move away from or close to the first positioning member 32.

[0037] In this embodiment, the top end of the third connecting plate 53 is provided with a first mounting groove 531 corresponding to the first positioning block 34, and the bottom end of the first positioning block 34 is arranged at the bottom of the corresponding first mounting groove 531. This structure can reduce the distance between the bottom end of the positioning plate 20 and the top end of the bracket 10, thereby reducing the overall height of the positioning mechanism.

[0038] The second drive assembly includes two second drive members 60 arranged symmetrically in front and back. The second drive members 60 are arranged at the top of the bracket 10 and below the positioning plate 20. Both second drive members 60 are located between the two mounting blocks 11 and are adjacent to the front and rear sides of the positioning plate 20, respectively. Two first support plates 61 are respectively located above the two second drive members 60. One end of each first support plate 61 is connected to the output end of the two second drive members 60 via a second connecting block 611. Two second support plates 62 are respectively located at the top of each first support plate 61. Both second support plates 62 are located below the positioning plate 20. The two second support plates 62 correspond to the two positioning groups. The two second support plates 62 and the two first support plates 61 are both located between the two mounting blocks 11. The bottom end of the second positioning block 35 of the positioning assembly 30 of one positioning group is located at the top of one of the second support plates 62, while the bottom end of the second positioning block 35 of the positioning assembly 30 of the other positioning group is located at the top of the other second support plate 62. The two third connecting plates 53 and the second connecting plate 52 are located between the two second support plates 62. The second driving member 60 is used to drive the corresponding first support plates 61 and second support plates 62 to move forward and backward, thereby driving the corresponding second positioning block 35 of the positioning assembly 30 to move away from or toward the second positioning member 33 through the second support plates 62.

[0039] In this embodiment, a second mounting groove 621 is provided at the top of the second support plate 62, and the bottom end of the second positioning block 35 of the positioning assembly 30 of the positioning group is arranged at the bottom of the second mounting groove 621. This structure can reduce the distance between the bottom end of the positioning plate 20 and the top end of the bracket 10, thereby reducing the overall height of the positioning mechanism.

[0040] The first driving member 50 and the second driving member 60 are both cylinders. It can be understood that the first driving member 50 and the second driving member 60 can also be, for example, oil cylinders, linear motors, etc.

[0041] In this embodiment, the bracket 10 includes a base plate 12, a top plate 13 positioned above the base plate 12, and a plurality of support columns 14 disposed between the base plate 12 and the top plate 13. The number of support columns 14 can be adjusted based on practical needs. The mounting block 11, the first drive member 50, and the two second drive members 60 are all disposed on top of the top plate 13. In actual use, the base plate 12 is mounted on top of the polishing mechanism of a polishing machine. This structure reduces the weight of the bracket 10, thereby reducing the weight of the positioning mechanism.
