[0030] Unlike Figure 1 In this embodiment, four spring clamping devices 4 are provided. The beam support 3 is a cross-shaped support beam.

The limiting movable plate 5 is installed above a circle with the center of the beam support 3 as the center and the distance between the center of the spring clamping device 4 and the center of the beam support 3 as the radius.

[0031] Example 3:

[0032] like Figure 1 , 2 As shown, an automated loading mechanism for spring assembly includes a rotating device 1, a lifting device 2, a beam support 3, a spring clamping device 4, and a limiting movable plate 5. The lifting device 2 is mounted on the rotating device 1, the beam support 3 is fixedly mounted on the lifting device 2 at its center, at least two spring clamping devices 4 are provided and symmetrically mounted on the beam support 3, and the limiting movable plate 5 is mounted above the beam support 3.

[0033] The rotating device 1 consists of a rotating cylinder and a rotating base, with the rotating base controlled by the rotating cylinder to rotate. The lifting device 2 consists of a telescopic base, a telescopic rod, and a telescopic cylinder. The telescopic base is mounted on the rotating base, and the telescopic rod is mounted on the telescopic base and controlled by the telescopic cylinder to move vertically up and down.

[0034] The spring clamping device 4 includes a sleeve 41 and a clamping body 42 installed at the lower end of the sleeve 41, as well as a return spring 43 and a spring base 44. A spring clamping groove 45 is provided on the lower end face of the clamping body 42. A pressure pin mounting hole 46, penetrating the spring clamping groove 45, is provided at the center of the sleeve 41 and the clamping body 42. A pressure pin 47 is installed in the pressure pin mounting hole 46, and the pressure pin 47 extends downward under the action of the lifting device 2 and the limiting movable plate 5.

[0035] Unlike Figure 1 In this embodiment, six, eight, or even ten spring clamping devices 4 are provided. The beam support 3 is a disc-shaped support beam or a circular support beam fixed by radial struts. The six, eight, or other spring clamping devices 4 are symmetrically installed at equal intervals on the disc or ring of the disc-shaped support beam or the circular support beam, with the center of the beam support 3 as the center point of symmetry. The limiting movable plate 5 is installed above a circle with the center of the beam support 3 as the center and the distance between the center of the spring clamping device 4 and the center of the beam support 3 as the radius.

[0036] In embodiments one, two, and three, the automated loading mechanism for spring assembly of the present invention controls the beam support 3 and the spring clamping device 4 to move up and down through the lifting device 2. When the spring clamping device 4 moves to the lowest position, one of the spring clamping devices 4 located at the two symmetrical ends clamps the spring parts in the raw material pool through the spring clamping groove 45 on the lower end face of the clamping body 42, while the other spring clamping device 4 provides the clamped spring parts to the spring assembly equipment for spring assembly. The rotating device 1 can control the lifting device 2, the beam support 3, and the spring clamping device 4 to rotate on the horizontal plane as a whole. The rotation angle each time (each step) depends on the number of spring clamping devices 4. For example, if there are two spring clamping devices 4, the rotation is 180° each time (each step); if there are four spring clamping devices 4, the rotation is 90° each time (each step); if there are six spring clamping devices 4, the rotation is 60° each time (each step); if there are eight spring clamping devices 4, the rotation is 45° each time (each step); and so on. After each rotation or step, the spring parts on the next spring clamping device 4 are clamped and loaded or assembled and unloaded. Meanwhile, if the spring component on the spring clamping device 4 fails to be successfully assembled and unloaded in a certain step, at a certain position during the rotation from clamping and loading to assembly and unloading, or at the assembly and unloading position, the lifting device 2 controls the spring clamping device 4 to rise. During this process, the spring base 44 of the spring clamping device 4 with the spring component acts on the limiting movable plate 5, causing the return spring 43 to deform. The pressure needle 47 extends downward and forward, acting on the unassembled spring component in the spring clamping groove 45 to remove it. After the lifting device 2 controls the spring clamping device 4 to descend, the return spring 43 resets, and the lower end of the pressure needle 47 retracts into the pressure needle mounting hole 46, thereby ensuring that the spring clamping device 4 can continue to clamp and load spring components during subsequent rotation.

[0037] The automated transport mechanism for spring assembly of the present invention, through the rotating device 1, the lifting device 2, and the spring clamping device 4 mounted on the beam support 3, can realize the clamping and transfer of spring components. Simultaneously, the pressure pin 47 can remove the spring components clamped in the spring clamping groove 45 on the lower end face of the clamping body 42, preventing interference and collision between spring components during subsequent clamping. The automated transport mechanism for spring assembly of the present invention, through the setting of the spring clamping device, realizes the clamping and removal of spring components, saving space and eliminating the need for additional external moving parts.

[0038] The automated loading and unloading mechanism for spring assembly of the present invention is ingeniously designed and has a simple structure. It can realize the clamping and transfer of spring parts, making spring removal simple and efficient. There will be no interference between the previous unused spring part and the next spring part to be clamped. It is simple and convenient to operate, has good stability and high efficiency, so as to facilitate the operation of subsequent automated equipment, save time and reduce the waste of labor costs.
