TECHNICAL FIELD

[0001] The application relates to a rotating shaft module assembling device. BACKGROUND

[0002] The rotating shaft module is also called a rotating hinge, a damping hinge or a damping shaft core, is a connecting element capable of providing a mutual rotating function, is mainly applied between a rotating part and a base, and is currently widely applied in various digital products and electronic devices, such as a notebook computer.

[0003] The traditional rotating shaft module product is generally assembled by a rotating shaft rod, a connecting plate, a spring, a cam piece, a gear and a gear arm. Meanwhile, the product is very small in size and is high in assembling precision. For this, the industry generally adopts a manual line assembling mode.

[0004] However, the following problems often occur in the above-mentioned assembling implementation process:

[0005] (1) The manual assembling mode is not only high in requirements for the operation skills and proficiency of workers, but also requires the workers to maintain high concentration for a long time.

In the present application, the two spring members 82 are compression springs.

[0051] For reference Figures 3 to 9 As shown, specifically, the lower die 1 is formed with a mounting cavity 10 recessed downwardly from the upper surface, and the bearing seat 2 is implanted in the mounting cavity 10 from top to bottom. Preferably, the bearing seat 2 can move in the mounting cavity 10 in the up-down direction, but cannot move in the mounting cavity 10 in the front-rear direction and the left-right direction. The lower die 1 is recessed to form a first sliding groove 101 extending in the left-right direction, and the first sliding groove 101 is communicated with the mounting cavity 10. The first driving assembly 3 comprises a first driving rod 31. The first driving rod 31 is inserted into the first sliding groove 101 and is connected with the bearing seat 2. The first driving rod 31 moves in the left-right direction and drives the bearing seat 2 to float in the mounting cavity 10 in the up-down direction.

[0052] A preferred embodiment is as follows: the first drive rod 31 extends generally in the left-right direction and is partially crank-shaped with a step segment 311. An inclined surface 310 is formed on the upper surface of the step segment 311. The support seat 2 has a through hole 20 extending in the left-right direction. The step segment 311 is inserted into the through hole 20. The movement of the inclined surface 310 in the left-right direction drives the support seat 2 to float in the up-down direction.

[0053] Please refer to the reference. Figures 4 to 6 and Figure 8 As shown, the upper mold 4 forms a limiting hole 40 extending through it in the vertical direction. The mounting cavity 10 communicates with the limiting hole 40 in the vertical direction. The width of the limiting hole 40 in the horizontal direction is greater than that of the mounting cavity 10 (mainly to accommodate the shape of the gear arm 85 and to allow the gear arm 85 to be supported on the upper surface of the lower mold 1 after being installed in the limiting hole 40) and is configured to accommodate two gear components 84 and two gear arms 85. Sliding grooves 102 are respectively recessed at corresponding positions on the lower surface of the upper mold 4 and the upper surface of the lower mold 3. After the upper mold 4 and the lower mold 3 are stacked in the vertical direction, the complete sliding groove formed by the sliding grooves 102 on the upper mold 4 and the lower mold 3 extends in the front-back direction and communicates with the receiving groove formed by the mounting cavity 10 and the limiting hole 40. The slider 5 is inserted in the front-to-back direction into a complete sliding groove formed by the sliding groove 102 on the upper mold 4 and the sliding groove 102 on the lower mold 3. Of course, in other embodiments, the sliding groove 102 may be formed only on the upper mold 4 or only on the lower mold 3.

[0054] Please refer to the reference. Figures 5 to 9 As shown, the slider 5 has a limiting end 51 at one end near the mounting cavity 10 in the front-back direction, and the limiting end 51 is located below the limiting hole 40 in the vertical direction. A pin hole 52 is recessed in the slider 5 in the vertical direction.

The second driving assembly 6 includes a driving rod 61 and a guide pin 62. The driving rod 61 is movable in the left-right direction. One end of the guide pin 62 is fixed to the driving rod 61, and the other end is inserted into the pin hole 52. When the driving rod 61 moves in the left-right direction, it synchronously moves the guide pin 62 in the left-right direction, and simultaneously the other end of the guide pin 62 slides in the pin hole 52, thereby driving the slider 5 to slide in the front-back direction.

[0055] In a preferred embodiment, the lower mold 1 has a recessed implantation groove 103 extending in the left-right direction. The implantation groove 103 communicates with the aforementioned pin hole 52 in the up-down direction. The drive rod 61 is inserted into and slidably limited within the implantation groove 103. A first compression spring 53 is also included. This first compression spring 53 is compressible in the front-back direction. One end of the first compression spring 53 abuts against the end of the slider 5 away from the limiting end 51 in the front-back direction. The other end of the first compression spring 53 directly or indirectly abuts against the first limiting part 11 of the lower mold 1 (in this embodiment, the first limiting part 11 is an independent component assembled and fixed to the end of the lower mold 1 in the front-back direction; of course, the first limiting part 11 can be integrally formed with the lower mold 1). A second compression spring 63 is also included. This second compression spring 63 is compressible in the left-right direction. One end of the second compression spring 63 abuts against the drive rod 61 (see reference). Figure 8 As shown, specifically, a stop portion 611 is formed on one end of the drive rod 61 extending in the up-down or front-back direction. The end face of the stop portion 611 is opposite to the end face of the lower mold 1 in the left-right direction. One end of the second compression spring 63 is correspondingly abutted against the end face of the stop portion 611. The other end of the second compression spring 63 is directly or indirectly abutted against the position of the second limiting portion 12 of the lower mold 1 (in this embodiment, the second limiting portion 12 is one end face of the lower mold 1 in the left-right direction).
