[0002] The phone bezel is the edge part around the phone's casing, usually made of metal or plastic. The phone bezel is not only an important part of the phone's appearance design, but also provides additional physical protection, reducing damage to the phone's internal circuitry and screen from external impacts. As the frame of the phone casing, the bezel provides support for the screen and back cover, maintaining the overall structural stability of the phone.

[0003] In the assembly and processing of mobile phone frames, the traditional manufacturing industry requires a large number of operators, which brings many problems to quality control. In order to effectively meet the automation requirements of modern manufacturing, under such circumstances, the introduction of automatic loading and clamping fixtures can reduce the labor intensity of workers and improve production efficiency.

[0004] Currently, in the assembly and processing of mobile phone frames, the existing clamping fixture structure lacks an automatic loading and clamping design, resulting in long waiting and interval times for the machine. This is not conducive to improving efficiency when repeatedly unloading and loading mobile phone frames. Summary of the Invention

The end of the output piston push rod and the ejector arm are fixedly connected. The output piston push rod is located inside the cylinder body, and the ejector arm connects to two output piston push rods.

[0011] Preferably, there are multiple disc springs, and the multiple disc springs are distributed at equal intervals.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example:

[0027] Reference Figure 1-6An automatic loading and clamping fixture for mobile phone frames includes a fixed plate 1, a support 2 mounted on the surface of the fixed plate 1, a platform plate 3 fixedly mounted on the top of the support 2, a side support plate 4 embedded in the middle of the side of the platform plate 3, and end support plates 5 mounted on the top and bottom of the platform plate 3. A hydraulic lifting module 6 is installed between the fixed plate 1 and the platform plate 3. The output end of the hydraulic lifting module 6 slides through the platform plate 3 and is mounted with an upper lifting connecting plate 7. A disc spring 8 is mounted on the other side of the upper lifting connecting plate 7, and a mounting plate is mounted on the other end of the disc spring 8. The material clamping plate 9, the side plate 4 and the end plate 5 are all fixedly equipped with thrust cylinder parts 10. Push block modules 11 are fixedly installed on both sides of the surface of the material clamping plate 9. The workpiece bearing mechanism 12 is installed on the other side of the push block module 11. The surface of the platform plate 3 is equipped with a product guiding module 13. The output end of the thrust cylinder part 10 installed on the end plate 5 is equipped with a limit push block 15. The surface of the limit push block 15 is slidably sleeved with a limit propulsion constraint sleeve 14. The limit propulsion constraint sleeve 14 is fixedly connected to the platform plate 3.

[0028] In this invention, the support 2 is provided with a first mounting bolt 201 in the middle, and the two ends of the support 2 are respectively assembled and fixed to the fixing plate 1 and the platform plate 3 by the first mounting bolt 201. The number of supports 2 is four.

[0029] In this invention, both the side plate 4 and the end plate 5 have an assembly slot 501 on their surfaces. Both the side plate 4 and the end plate 5 have a second assembly bolt 502 installed in their assembly slots 501. Both the side plate 4 and the end plate 5 are fixed to the platform plate 3 by the second assembly bolt 502.

[0030] In this invention, the thrust cylinder section 10 includes a cylinder body 1001, an output piston push rod 1002, and an ejection end arm 1003. The end of the output piston push rod 1002 and the ejection end arm 1003 are fixedly connected. The output piston push rod 1002 is located inside the cylinder body 1001. The ejection end arm 1003 is connected to two output piston push rods 1002.

[0031] More specifically, by setting the push-out end arm 1003 to be driven by two connected output piston push rods 1002, it can maintain balance and stability during movement and avoid the occurrence of skew.

[0032] In this invention, there are multiple disc springs 8, and the multiple disc springs 8 are distributed at equal intervals;

[0033] More specifically, setting multiple equally spaced disc springs 8 can better provide deformation space during compression and reset.

[0034] In this invention, there are two side plates 4 and two end plates 5, and eight thrust cylinder sections 10. The eight thrust cylinder sections 10 are divided into four groups of two adjacent sections, that is, the four groups of thrust cylinder sections 10 are respectively installed on two side plates 4 and two end plates 5.

[0035] More specifically, by setting eight thrust cylinder sections 10 into four groups of two adjacent sections, the output end of two thrust cylinder sections 10 provides driving force, making the structure's driving motion more stable.

[0036] In this invention, there are two hydraulic lifting modules 6, and the output ends of the two hydraulic lifting modules 6 are respectively fixedly connected to the top and bottom of the lifting connecting plate 7.

[0037] More specifically, by setting up a hydraulic lifting module 6 to drive and connect the lifting connecting plate 7, the stability of the movement and displacement of the lifting connecting plate 7 is ensured.

[0038] In this invention, the side of the push block module 11 away from the output end of the thrust cylinder section 10 is connected to the side surface of the workpiece bearing mechanism 12 via a connecting rod structure.

[0039] More specifically, by setting the side of the push block module 11 away from the output end of the thrust cylinder section 10 to overlap with the side surface of the workpiece bearing mechanism 12 through a connecting rod structure, interference with the longitudinal displacement of the workpiece bearing mechanism 12 structure is avoided.

[0040] Working principle: When the entire fixture device fixes the mobile phone frame workpiece, the mobile phone frame workpiece is clipped onto the top of the workpiece bearing mechanism 12, while the loading and clamping plate 9 fixed at the bottom of the workpiece bearing mechanism 12 is supported by the disc spring 8. The deformation of the disc spring 8 can cause the workpiece to move down as a whole. The operator places the mobile phone frame workpiece on the product guide module 13, which can be driven by the thrust cylinder 10 to drive the output end structure limit push block 15 and push block module 11 to fix the workpiece surface. Under the reset action of the disc spring 8, the workpiece is pushed to the original height position, providing structural contact fixation.

[0041] In summary, this automatic loading and clamping fixture for mobile phone frames utilizes disc springs to provide support for the loading and clamping plate 9 and the workpiece carrying mechanism 13. It allows for the insertion and clamping of mobile phone frames, enabling the thrust cylinder 10 to drive and control the limit push block 15 and push block module 11 to automatically clamp the mobile phone frame workpiece. The workpiece carrying mechanism 12 is supported on the inner side of the mobile phone frame, preventing deformation due to external pressure. This avoids the inconvenience of requiring manual screwing for product tightening in traditional methods, reducing operator workload and significantly decreasing machine waiting and interval times. It eliminates the need for repeated unloading and loading of mobile phone frame workpieces, enabling low-cost and rapid automated production, greatly improving production efficiency and product quality. It solves the problems of existing clamping fixtures lacking automatic loading and clamping design, long machine waiting intervals, and the inefficiency caused by repeated unloading and loading of mobile phone frames.
