[0032] The present invention will now be described in detail with reference to the accompanying drawings.

[0033] like Figure 1-5As shown, a mobile phone glass centering fixture includes a positioning base plate 1. Multiple positioning modules 10 are mounted on the top of the positioning base plate 1, and the multiple positioning modules 10 are equidistantly mounted on the positioning base plate 1. Each positioning module 10 includes a cylinder base 11. Drive arms 12 that simultaneously open or retract are mounted on the four sides of the cylinder base 11. Two opposing drive arms 12 have upright first clamping arms 13 mounted at their ends, and the other two opposing drive arms 12 have upright second clamping arms 14 mounted at their ends. The inner sides of the first clamping arm 13 and the second clamping arm 14 are both formed with a bottom support surface 15 for supporting the mobile phone glass and a side support surface 16 that contacts the side wall of the mobile phone glass. The first clamping arm 13 and the second clamping arm 14 are both provided with a buffer structure that elastically contacts the side wall of the mobile phone glass. The cylinder base 11 is also equipped with a central support device, which includes a central circular groove 17 formed in the center of the cylinder base 11. The central circular groove 17 is equipped with a lifting cylinder and a lifting block 18 connected to the drive end of the lifting cylinder.

[0034] Initially, the two clamping arms 13 and 14 located on the cylinder base 11 move outwards respectively, leaving a large space for the mobile phone glass to be placed in. After the mobile phone glass is placed in, the lifting block 18 of the central support device rises. Then, the first clamping arms 13 and 14 retract synchronously under the action of pneumatics. The first clamping arms 13 and 14 support the bottom surface of the mobile phone glass through the bottom support surface 15 and contact the side wall of the mobile phone glass through the side support surface 16 to achieve clamping and positioning. During clamping, the buffer structure has an elastic contact effect, which can reduce the scratches on the side, top and bottom surfaces of the mobile phone glass, ensure the quality of the mobile phone glass, and improve the yield rate.

[0035] In one embodiment, the buffer structure includes a first buffer structure 2 disposed on the first clamping arm 13. The first buffer structure 2 includes a first bottom support block 22 and a first side support block 21 formed of silicone material. The first bottom support block 22 is disposed on the bottom support surface 15, and the side support surface 16 is formed with a side mounting groove. The first side support block 21 is installed in the side mounting groove. By simultaneously supporting and positioning the bottom and side surfaces of the mobile phone glass with the first side support block 21 and the first bottom support block 22, fixation is achieved, which can reduce the possibility of scratches on the sides, top, and bottom surfaces of the mobile phone glass and ensure the quality of the mobile phone glass. The two first clamping arms 13 simultaneously approach each other, clamping two opposite sides of the mobile phone glass.

[0036] Furthermore, the bottom support surface 15 has a recessed bottom mounting groove 23, on which an adjusting rod 24 capable of longitudinal movement is mounted. A top connecting plate 25 is mounted on the top of the adjusting rod 24, and the first bottom support block 22 is mounted on the top connecting plate 25. The bottom mounting groove 23 has a bottom adjusting hole 26 that mates with the adjusting rod 24. The adjusting rod 24 can rotate and move up and down through the bottom adjusting hole 26. A bearing seat 27 is mounted on the top of the adjusting rod 24, and the bearing seat 27 is connected to the top connecting plate 25. The height of the adjusting rod 24 can be changed by rotating it in conjunction with the bottom adjusting hole 26, thereby changing the height of the top connecting plate 25 used to mount the bottom support block. The bottom adjusting hole 26 is a threaded hole. When the adjusting rod 24 rotates, the top connecting plate 25 will not rotate because the top of the adjusting rod 24 is the bearing seat 27, and it can move up and down stably within the bottom mounting groove 23. After the height of the top connecting plate 25 with the bottom support block is changed, it can support mobile phone glass of different thicknesses, further improving its practicality.

[0037] It should be noted that the cylinder base 11 is a pneumatic clamp structure. The pneumatic clamp has four drive ends, which are located in the front, back, left, and right directions of the pneumatic clamp, respectively. Together with the two first clamping arms 13 and the two second clamping arms 14, they form a four-jaw structure to achieve clamping and positioning of the mobile phone glass. The four-drive pneumatic clamp is a common structure in the field of clamping and positioning. Those skilled in the art can deduce without creative effort that the four drive ends achieve telescopic movement through a pneumatic system.

[0038] In one embodiment, the buffer structure includes a second buffer structure 3 disposed on the second clamping arm 14. The second buffer structure 3 includes a second bottom support block 31 formed by processing silicone material. The second bottom support block 31 is installed on the bottom support surface 15 of the second clamping arm 14. The two second clamping arms 14 approach each other at the same time, and clamp the other two opposing sides of the mobile phone glass by contacting the bottom surface of the mobile phone glass with the support surface 16 through the second bottom support block 31.

[0039] Furthermore, the side support surface 16 of the second clamping arm 14 is formed with a concave driving groove 32. A side guide block 33 made of silicone material is slidably installed in the driving groove 32. The side guide block 33 is formed with a concave buffer groove 34. The buffer groove 34 can softly fit with one side of the mobile phone glass and part of the top and bottom surfaces. When the side support surface 16 of the second clamping arm 14 contacts the outer wall of the mobile phone glass through the side guide block 33, and when the side guide block 33 contacts the outer part of the mobile phone glass through the buffer groove 34, the side guide block 33 can elastically clamp the outer part of the mobile phone glass through the buffer groove 34, which can prevent scratches and improve the stability of clamping.

[0040] Preferably, the buffer groove 34 is formed with a guide flare structure 35, which can improve the fit between the buffer groove 34 of the side guide block 33 and the side of the mobile phone glass, making it easier for the mobile phone glass to enter the buffer groove 34.

[0041] Furthermore, the drive groove 32 is also formed with an external threaded hole 36, on which a rotating threaded rod 37 is installed. A movable sleeve 38 is movably sleeved at the inner end of the rotating threaded rod 37. The movable sleeve 38 is connected to the side guide block 33 and can move along the length of the rotating threaded rod 37. A compression spring 40 is sleeved at the inner end of the rotating threaded rod 37 between the movable sleeve 38 and the side wall of the drive groove 32. A stop block 39 is installed at the outer end of the rotating threaded rod 37 and engages with the external threaded hole 36. By twisting the rotating threaded rod 37, the length of the rotating threaded rod 37 in the drive groove 32 changes. When the length is different, the elastic force is also different, and the elastic force of the movable sleeve 38 in contact with the side guide block 33 is also different. According to the hardness of the mobile phone glass, the corresponding elastic force is adjusted to make it more stable during side contact.

[0042] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0043] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
