[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0038] Example

[0039] In order to make such Figure 1 The PIN pins shown quickly connect the top cover to the leaf spring for installation. (Refer to...) Figure 2 and Figure 6 As shown, this application discloses an upper cover leaf spring assembly mechanism, including a carrier 10, an assembly fixture 20, and a PIN needle feed head 30;

[0040] The assembly fixture 20 includes a fixture seat 21 located on one side of the carrier 10, a contour seat 22 located above the fixture seat 21 for placing the top cover, an elastic block 23 located on one side of the fixture seat 21 for abutting one side of the top cover, a clamping block 24 slidably located on the other side of the carrier 10 and cooperating with the elastic block 23 for clamping the top cover, a flipping pressure block 25 hinged on one side of the fixture seat 21 for pressing the top cover, and a linkage drive unit 26 located on the carrier 10 and linked to the clamping block 24 and the flipping pressure block 25.

[0041] The PIN needle feed head 30 is located on the lateral side of the carrier 10 to position the PIN needle into the upper cover and connect it to the inside of the spring plate.

[0042] Based on the above structure, during the installation of the top cover and the leaf spring, the top cover is first placed inside the contour seat 22, and then the leaf spring is placed inside the top cover (after the leaf spring is placed inside the top cover, the inner hole of the leaf spring will correspond to the inner hole of the top cover). After that, the linkage drive unit 26 drives the flipping pressure block 25 and the clamping block 24 to move synchronously. During this process, the clamping block 24 will cooperate with the elastic block 23 to clamp the top cover, while the flipping pressure block 25 flips and presses on the top cover. Finally, the PIN needle is pushed from the outside of the top cover into its interior through the PIN needle feed head 30, so that the PIN needle assembles the top cover and the leaf spring.

[0043] In one embodiment, the elastic block 23 of this application includes a support 231, a T-shaped block 232, a pin 233, and a spring 234. The support 231 is mounted on the carrier 10. A guide hole 2312 is formed in the interior of the support 231 along the lateral direction. The T-shaped block 232 passes through the interior of the guide hole 2312 and is positioned so that its lateral portion faces the contour seat 22. The spring 234 is sleeved between the lateral portion of the T-shaped block 232 and the support 231. The interior of the support 231 has a guide hole along the height direction. The T-shaped block 232 has a waist-shaped groove 2321 on its horizontal part, and the pin 233 is inserted into the socket 2311 from the top of the support 231 and extends through the waist-shaped groove 2321 on the T-shaped block 232. When the linkage drive unit 26 drives the clamping block 24 to move, the clamping block 24 will push the upper cover from one side until the other side of the upper cover abuts against the elastic block 23. In this way, the upper cover can be flexibly clamped, which can avoid damage to the upper cover compared with rigid clamping.

[0044] In one installation method, the present application provides slide rails 70 on both longitudinal sides of the carrier 10, and a sliding plate 80 is slidably connected above the two slide rails 70. The clamping block 24 is fixed on the sliding plate 80 and extends in the direction of the contour base 22. The linkage drive unit 26 passes through the carrier 10 and is connected to the sliding plate 80. When the linkage drive unit 26 drives the sliding plate 80 to move, the sliding plate 80 will move stably on the two slide rails 70. In this way, the clamping block 24 can move stably.

[0045] During installation, in order to detect whether the leaf spring is tilted, this application provides a platform 40 covering the sliding plate 80 on the longitudinal side of the carrier 10. Above the platform 40 is a light sensor 50 corresponding to the PIN needle feed head 30. When the leaf spring is placed inside the top cover, the light sensor 50 will emit light to detect whether the small hole on the outside of the leaf spring is connected to the small hole on the outside of the top cover.

[0046] Furthermore, in order to prevent the platform 40 from interfering with the movement of the clamping block 24, this application provides a first clearance groove 41 on the platform 40, and the clamping block 24 is located inside the first clearance groove 41 and can be moved out of the clearance groove.

[0047] To prevent the flipping block 25 from directly contacting and damaging the leaf spring during the flipping process, this application provides a second clearance groove 251 inside the flipping block 25 corresponding to the leaf spring. In this way, the flipping block 25 can avoid contact with the leaf spring after flipping. In addition, this application also includes an air blowing unit 60, which includes a bracket 61, a horizontal rod 62 and an air blowing pipe 63. The bracket 61 is located outside the base plate, the horizontal rod 62 faces the base plate and is fixed to the bracket 61 in the horizontal direction, and the air blowing pipe 63 passes through the inside of the horizontal rod 62 and extends outward to face the second clearance groove 251. When the leaf spring is placed on the top cover, the air blowing pipe 63 blows air through the second clearance groove 251 to press down the outer end of the leaf spring, thereby ensuring that the outer end of the leaf spring will not be lifted.

[0048] Based on the structure of the air blowing unit 60, this application also provides a support block 64 above the bracket 61, and the PIN needle feed head 30 is located above the support block 64 and extends inward toward the contour seat 22. In this way, the PIN needle feed head 30 is installed and fixed.

[0049] In order to achieve hinged fixation of the flipping pressure block 25, this application provides a support block 252 on the longitudinal side of the fixture base 21, and the flipping pressure block 25 is hinged to the support block 252 through the hinge shaft 253.

[0050] In one specific embodiment, the present application also provides a cavity (not shown in the present application) inside the lower part of the carrier 10;

[0051] The linkage drive unit 26 includes a rotating plate 261, a telescopic arm 262, a hinged arm 263, a telescopic drive component 264, a push arm 265, and a push plate 265. The rotating plate 261 is disposed inside the cavity, and its middle part is connected to the bottom of the carrier 10 through a rotating shaft 2611. The telescopic arm 262 is connected to one end of the rotating plate 261 inside the cavity through a first connecting shaft 2612. One end of the hinged arm 263 is hinged to the telescopic arm 262 inside the cavity. The other end of the hinged plate 265... The end is hinged to the flipping pressure block 25 inside the cavity. The telescopic drive component 264 is located outside the carrier 10 and connected to the telescopic arm 262. The push arm 265 is connected to the other end of the rotating plate 261 via the second connecting shaft 2613. A third clearance groove 11 is provided on one side of the carrier 10. The push plate 265 is located above the carrier 10 and its bottom passes through the third clearance groove 11 and is connected to the push arm 265. An obtuse-angled groove 266 is provided on the upper surface of the push plate 265. 1. The bottom of the clamping block 24 is connected to a sliding shaft 241, which can be slidably disposed inside the obtuse-angled groove 2661. When the upper cover is placed inside the contour seat 22 and the leaf spring is placed inside the upper cover, the telescopic drive 264 drives the telescopic arm 262 to move. At this time, the rotating plate 261 will rotate through the first connecting shaft 2612 and the second connecting shaft 2613. The first connecting shaft 2612 will drive the telescopic arm 262 to rotate, so that the hinge arm 263 will drive the flipping clamping block 24 to flip until it clamps the upper cover. The second connecting shaft 2613 will drive the push plate 266 to move through the push arm 265, so that the clamping block 24 moves with the sliding shaft 241 in the obtuse-angled groove 2661 until it clamps the upper cover. Based on the above structure and operation principle, the linkage drive unit 26 of this application can synchronously drive the clamping block 24 and the flipping pressing block 25 to clamp and press the upper cover. It has high work efficiency and ensures that the upper cover is accurately placed.

[0052] In addition, in specific implementations, the telescopic drive component 264 of this application may be selected from one of the following: a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, or other telescopic drive structures may be adopted, which will not be elaborated on here.

[0053] Based on the above solution, this application also provides third connecting shafts 2614 on both sides of the middle part of the rotating plate 261, and two fourth connecting shafts 267 at the bottom of the carrier 10. A tension spring 268 is connected between the two fourth connecting shafts 267 and the two third connecting shafts 2614. When the telescopic drive 264 drives the telescopic arm 262 to extend or retract, it can ensure that the rotating plate 261 has a certain tension. In this way, the flipping pressure block 25 will not press the upper cover instantly, and the clamping block 24 will not clamp the upper cover instantly.
