Description

Technical Field

[0001] This utility model relates to the field of rotating shaft product assembly technology, and in particular to a rotating shaft product assembly 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 assembly process of a rotating shaft, the precise assembly of the retaining ring is a crucial step in ensuring product performance and stability. However, the current design of retaining rings is extremely thin, making them very fragile and prone to deformation with the slightest carelessness. Furthermore, the retaining rings also feature a special convex structure, further increasing the complexity and uncertainty of the assembly process. When assembling retaining rings manually, it is difficult to precisely control their position and orientation, easily leading to problems such as retaining ring tilting and convex jamming, resulting in a significantly increased assembly failure rate. Moreover, improper assembly operations can damage the retaining ring itself and other related parts, affecting the overall quality of the rotating shaft. Existing assembly technologies and tools lack effective assembly solutions for these thin retaining rings with convex structures, failing to meet the demands for precise and efficient assembly in actual production. Therefore, there is an urgent need to develop new assembly devices to solve this problem. Utility Model Content

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

[0017] Please see Figures 1 to 11 The rotating shaft product assembly device according to one embodiment of the present utility model includes a worktable 10, a first push-in component 20 installed at one end of the worktable 10, an upper mold component 30 detachably connected to the first push-in component 20, a second push-in component 40 installed below the first push-in component 20, and a lower mold component 50 detachably connected to the second push-in component 40.

[0018] The first push-in component 20 includes a column 21 installed at one end of the worktable 10, a lifting seat 22 slidably connected to one side of the column 21, and a first quick clamp 23 connected above the lifting seat 22; the first quick clamp 23 is used to drive the lifting seat 22 and the upper mold component 30 to press down.

[0019] Specifically, the front of the lifting seat 22 is provided with a receiving groove 220, and a first magnet (not shown) is installed on the lifting seat 22 corresponding to the inside of the receiving groove 220.

[0020] The upper mold assembly 30 includes a back shell 31 and a front shell 32 that matches and snaps onto the back shell 31; the back shell 31 and the front shell 32 are used to clamp the upper part 60 of the rotating shaft. During assembly, the upper mold assembly 30 is embedded in the receiving groove 220, and the first magnet attracts the back shell 31 for fixation.

[0021] In this embodiment, as Figure 4 As shown, the upper part 60 of the rotating shaft includes a base 61, cantilever 62 rotatably connected to opposite sides of the base 61, and a central shaft 63 coaxially connected to each cantilever 62; the central shaft 63 and the cantilever 62 can rotate relative to each other.

[0022] The second push-in assembly 40 includes a positioning seat 41 located below the lifting seat 22 and a second quick clamp 42 located on the side of the positioning seat 41 facing away from the column 21. The positioning seat 41 is used to support the lower mold assembly 50, and the second quick clamp 42 is used to laterally press the lower mold assembly 50.

[0023] Specifically, a second magnet (not shown) is provided on one side of the positioning seat 41. The second magnet is used to attract and fix the lower mold assembly 50.

[0024] The lower mold assembly 50 includes a support 51, an isolation part 52 fixedly connected inside the support 51, a limiting block 53 elastically installed on one side of the isolation part 52, a push-in block 54 elastically installed on the other side of the isolation part 52, a clamping block 55 elastically installed above the push-in block 54, and an ejector pin 56 elastically passing through the isolation part 52.

[0025] The support 51 is housed on the positioning seat 41, and the second magnet attracts the support 51, realizing a detachable connection between the lower mold assembly 50 and the second push-in assembly 40. The top surface of the part of the push-in block 54 that extends beyond the clamping block 55 is used to support the retaining spring 80, and the top surface of the retaining spring 80 is flush with the top surface of the limiting block 53.

[0026] Specifically, such as Figure 11 As shown, the top surface of the portion of the push-in block 54 that extends beyond the clamping block 55 has a placement recess. A third magnet 57 is installed on each of the opposite sides of the interior of the push-in block 54 corresponding to the placement recess. The placement recess is used to accommodate the retaining ring 80, and the third magnet 57 attracts the retaining ring 80, thus positioning it through attraction. The tip of the ejector pin 56 passes through and protrudes beyond the top surface of the isolating part 52 to position and clamp the lower part 70 of the rotating shaft, and the ejector pin 56 is coaxial with the central shaft 63.

[0027] In this embodiment, the lower part 70 of the rotating shaft includes a baffle 71, a damping spring 72, and a cam seat 73 stacked in sequence; the ejector pin 56 passes through the baffle 71, the damping spring 72, and the cam seat 73 in sequence, wherein the baffle 71 is used to abut against the top surface of the limiting block 53.

[0028] Please refer to it again. Figure 7 The limiting block 53 has limiting and avoiding grooves 530 on opposite sides at its end, which are used to match and avoid the ejector pin 56 or the central shaft 63. The pushing block 54 has pushing and avoiding grooves 540 on opposite sides at its end, which are used to match and avoid the ejector pin 56 or the central shaft 63.

[0029] During actual assembly, the working process of the assembly device for this shaft product is as follows: Preliminary preparation: The operator inserts the upper mold assembly 30, which is clamped with the upper part of the rotating shaft 60, into the receiving groove 220 of the lifting seat 22, and fixes it by adsorbing the back shell 31 with the first magnet; at the same time, the lower mold assembly 50, which is clamped with the lower part of the rotating shaft 70, is placed on the positioning seat 41 and fixed by adsorbing it with the second magnet. At this time, the ejector pin 56 passes through the baffle 71, the damping spring 72 and the cam seat 73 and forms a positioning for them.

[0030] Preliminary assembly: The operator operates the first quick clamp 23 with one hand, driving the lifting seat 22 and the upper mold assembly 30 to move downward. During this process, the central shaft 63 inside the upper mold assembly 30 presses the ejector pin 56 downward, causing the ejector pin 56 to retract into the isolation part 52. At this time, the central shaft 63 replaces the position of the ejector pin 56. The central shaft 63 passes through the cam seat 73, the damping spring 72 and the baffle 71 in sequence, completing the preliminary assembly of the lower part 70 and the upper part 60 of the rotating shaft.

[0031] Complete Assembly: The operator uses their other hand to operate the second quick clamp 42, driving the push block 54 to move towards the isolation section 52. During the movement, the push block 54 displaces the limiting block 53, and the retaining spring 80 it carries moves with the push block 54 to below the baffle 71. Finally, under the pushing action of the push block 54, the retaining spring 80 is engaged with the central shaft 63, and the retaining spring 80 abuts against the bottom surface of the baffle 71. The protrusion 81 of the retaining spring 80 is embedded in the recess of the baffle 71 (not shown), achieving complete assembly of the lower part 70 and the upper part 60 of the rotating shaft, forming the finished rotating shaft product. During this process, the clamping block 55 is located above the retaining spring 80 and abuts against the side of the baffle 71, which can effectively prevent the retaining spring 80 from bouncing during installation and ensure smooth assembly.

[0032] Finished product unloading: After the shaft product is finished, the operator releases both hands, the ejector pin 56 resets, and lifts the finished shaft product so that the operator can take it away.

[0033] The above-mentioned rotating shaft product assembly device has a simple structure and is easy to use. The lifting seat 22 and the upper mold assembly 30 position the upper part 60 of the rotating shaft, and the ejector pin 56 coaxially positions the lower part 70 of the rotating shaft. The central shaft 63 replaces the ejector pin 56 and passes through the lower part 70 of the rotating shaft. The push-in block 54 drives the snap ring 80 to fasten the central shaft 63, which simplifies two-hand operation, reduces assembly failure and part damage, and improves assembly quality and efficiency.

[0034] 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.

[0035] 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.
