Technical Field

[0001] This utility model relates to the field of hinge retaining spring disassembly technology, and in particular to a hinge retaining spring disassembly device. Background Technology

[0002] With the rapid development of foldable screen phone technology, the hinge of a foldable screen phone, as the core component to realize the screen folding function, directly determines the hinge's opening and closing feel and long-term reliability, playing a crucial role in user experience and product competitiveness.

[0003] In the actual manufacturing process of hinges, due to the combined effects of various factors such as inconsistent incoming material quality and human error, a certain proportion of defective products are inevitably generated after assembly. Some of the components in these defective products may not have inherent quality problems; the failure is simply due to issues arising at certain stages of the assembly process. To effectively reduce production costs and improve resource utilization, recycling the good components from assembled hinge products is crucial. However, recycling these components requires precise and efficient disassembly of the defective hinges. How to ensure the smooth removal of good components during disassembly while avoiding secondary damage has become a pressing technical problem to be solved. Utility Model Content

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0033] 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 invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] Please see Figures 1 to 10 This invention provides a hinge retaining ring disassembly device according to one embodiment of the present invention, comprising a support frame 10, a clamping assembly 20 mounted on the top surface of the support frame 10, and a lifting assembly 30 mounted inside the support frame 10; the clamping assembly 20 is used to clamp the hinge product 40. Wherein, as... Figure 6 As shown, the hinge product 40 includes a hinge base 41, a pivot 42 rotatably connected to opposite sides of the hinge base 41, a damping spring 43 sleeved on the pivot 42, a baffle 44 slidably connected to the pivot 42, and a retaining ring 45 snapped onto the end of the pivot 42. The damping spring 43 and the baffle 44 are connected to the hinge base 41 via the connection between the retaining ring 45 and the pivot 42, with the damping spring 43 sandwiched between the hinge base 41 and the baffle 44. Simultaneously, the damping spring 43 also causes the retaining ring 45 to abut against the end of the pivot 42, achieving a locking effect.

[0035] A first through groove 11 is provided at one end of the top surface of the support frame 10, and the first through groove 11 connects to the interior of the support frame 10.

[0036] The clamping assembly 20 includes a lower mold 21 installed at one end of the top surface of the support frame 10, an upper mold 22 that matches and covers the lower mold 21, a center pin 23 connected to the middle of the lower mold 21, a limiting block 24 connected to one end of the lower mold 21, a push-pull member 25 located at the end of the lower mold 21 away from the limiting block 24, and a lateral pressure block 26 connected to the end of the push-pull member 23; the lateral pressure block 26 is close to the lower mold 21. The lower mold 21 has a second through groove 210 at the end away from the limiting block 24, which corresponds to the first through groove 11 and is also corresponding to the retaining spring 45.

[0037] Specifically, the lower mold 21 is used to place the hinge product 40, and the upper mold 22 covers the lower mold 21 to clamp the hinge product 40. The center pin 23 is used to position and pass through the hinge base 41, and the limiting block 24 abuts against one end of the hinge base 41.

[0038] In this embodiment, the push-pull component 25 is a quick clamp.

[0039] In this embodiment, the edge of the baffle 44 protrudes beyond the retaining spring 45. That is, during the disassembly process, the push-pull member 25 drives the lateral pressure block 26 to squeeze the baffle 44 and compress the damping spring 43, thereby releasing the retaining spring 45 from the clamping state of the rotating shaft 42, which facilitates the subsequent disassembly of the retaining spring by the lifting assembly 30.

[0040] The lifting assembly 30 includes a fixed block 31 fixedly installed inside one side of the support frame 10, a movable block 32 slidably connected to one side of the fixed block 31, a handle 33 connected to the end of the movable block 32 facing away from the fixed block 31, a guide rod 34 connected to the end of the movable block 32 facing the fixed block 31, a return spring 35 sleeved on the guide rod 34, and a lifting plate 36 that can be raised and lowered above the movable block 32. The guide rod 34 is used to slide through the fixed block 31, and the return spring 35 is clamped between the movable block 32 and the fixed block 31. The bottom end of the lifting plate 36 abuts against the top of the movable block 32, and the top end of the lifting plate 36 passes through the first through slot 11 and the second through slot 210 to lift the retaining spring 45 upwards.

[0041] In this embodiment, the movable block 32 is slidably installed inside the support frame 10. The top of the movable block 32 has an inclined guide surface 320, the height of which gradually decreases from the handle 33 toward the fixed block 31. The bottom of the lifting plate 36 has an inclined mating surface (not shown), which matches and fits the guide surface 320. The lateral movement of the movable block 32 drives the lifting plate 36 to move longitudinally.

[0042] Furthermore, a magnet 37 is installed inside the bottom end of the lifting plate 36. The magnet 37 is used to attract the moving block 32, so that the lifting plate 36 has a better downward reset capability and can better drive the lifting plate 36 to retract into the lower mold 21 for convenient use in the next disassembly cycle.

[0043] In this embodiment, the lifting plate 36 and the baffle 44 are staggered. The top of the lifting plate 36 is provided with an avoidance opening 360, which corresponds one-to-one with the side pressure block 26 to avoid interference between the lifting plate 36 and the side pressure block 26, and to facilitate the lifting plate 36 to lift the retaining spring 45.

[0044] The aforementioned hinge retaining spring disassembly device has a simple structure and is easy to use. The limiting block 24 and the lateral pressing block 26 work together to release the retaining spring 45. The moving block 32 drives the lifting plate 36, so that the top of the lifting plate 36 passes through the support frame 10 and the lower mold 21 and lifts the retaining spring 45 upward. This allows for quick and accurate disassembly of the hinge product, avoiding secondary damage to the parts.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
