[0042] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0043] Reference Figure 3 and Figure 6In this embodiment, the cover mounting base 21 is movably mounted on the fixture 20, the button mounting base 22 is located a distance below the cover mounting base 21, the alignment device 60 is mounted on the frame 10 and corresponds to the pin mounting position, the alignment device 60 is used to drive the cover mounting base 21 to move down so that the pin hole of the cover is aligned with the pin hole of the button, and the fixture 20 is provided with a reset device for driving the cover mounting base 21 to move up and reset. Thus, when the fixture 20 is at the loading station and the spring installation station, the reset device can hold the cover mounting seat 21 in the upper position of the fixture 20, facilitating the loading of the cover and button, and avoiding interference with the spring installation. When the fixture 20 reaches the pin installation station, the alignment device 60 can move the cover mounting seat 21 downwards, aligning the pin hole of the cover with the pin hole of the button, allowing the pin installation device 50 to perform the pin assembly operation. After the pin is installed, the alignment device 60 releases the drive of the cover mounting seat 21, and the reset device drives the cover mounting seat 21 to reset, facilitating subsequent operations and simplifying the structure of the fixture 20, thus reducing equipment costs. In this embodiment, the alignment device 60 includes an alignment pressure block 61 and an alignment drive device 62. The alignment drive device 62 can drive the alignment pressure block 61 to move up and down. The alignment pressure block 61 pushes the cover mounting seat 21 downwards by abutting against it. The structure is simple and easy to manufacture and apply. The alignment drive device 62 uses a cylinder. In other embodiments, the alignment drive device 62 can also use other commonly used drive structures such as a motor-driven lead screw mechanism. In other embodiments, the alignment device 60 can also use other commonly used structures such as a pull-down mechanism or a gear and rack transmission structure to move the cover mounting base 21 downward. In this embodiment, the cover mounting base 21 is slidably mounted on the fixture 20 via a slide rail mechanism, which ensures the smooth movement of the cover mounting base 21. The reset device uses tension springs to connect both sides of the cover mounting base 21 to the fixture 20. The structure is simple and practical, easy to manufacture and apply. In other embodiments, the reset device can also use other elastic structures or drive structures such as cylinders or motors.

[0044] In other embodiments, a driving structure can be provided on the fixture 20 to drive the cover mounting base 21 to move. For example, a cylinder or motor can be used on the fixture 20 to drive the cover mounting base 21 to move up and down to achieve the movement of the cover mounting base 21 and the button mounting base 22 closer or further apart.

[0045] Similarly, in other embodiments, the button mounting base 22 can be moved by providing a corresponding driving device on the frame 10 or fixture 20 to achieve the movement of the cover and the button closer or further apart, or the button mounting base 22 and the cover mounting base 21 can be moved simultaneously to achieve the movement of the cover and the button closer or further apart. In addition, the button mounting base 22 and / or the cover mounting base 21 can also be moved by other common methods such as rotation or swinging to achieve the movement closer or further apart, and the relative positions of the button mounting base 22 and the cover mounting base 21 can also be flexibly adjusted as needed, and are not limited to this.

In use, the spring feeder 41 continuously outputs springs to the spring feeding track 42, ensuring the track is fully covered. A spring at the spring feeding position 45 can block further movement of subsequent springs. Since the distance between the spring feeding position 45 and the outlet end of the spring feeding track 42 is equal to or greater than the spring length but less than twice the spring length, it ensures that the next spring at the spring feeding position 45 is partially or completely located within the spring feeding track 42. The blocking device 43 prevents the spring from moving off the track. The first driving device 46 drives the spring feeding seat 44 to move, displacing the spring feeding position 45 from the spring feeding track 42, facilitating the spring moving device 47 to remove the spring from the spring feeding seat 44. Simultaneously, the spring moving device 47 moves the spring to the button on the fixture 20 at the spring installation position, completing the spring installation. This spring installation device 40 has an ingenious structure, enabling efficient installation of individual springs and facilitating manufacturing and application. In this embodiment, the spring feeder 41 uses a vibrating screen, and the spring feeding track 42 conveys springs through its internal feeding holes, preventing the springs from coming out. The blocking device 43 includes a blocking member 431 and a blocking drive device 432. The blocking drive device 432 can drive the blocking member 431 to move so that the blocking member 431 can be inserted into the spring feeding track 42, restricting the movement of the spring at the outlet of the spring feeding track 42. The structure is simple and easy to manufacture and apply. In other embodiments, the blocking device 43 can also adopt other commonly used blocking structures such as a flip-plate structure, and the spring feeder 41 and the spring feeding track 42 can also adopt other commonly used feeding and conveying structures, and are not limited to these. In this embodiment, both the first drive device 46 and the blocking drive device 432 use cylinders, which are simple in structure and easy to install and use. In other embodiments, the first drive device 46 and the blocking drive device 432 can also adopt other commonly used drive structures such as motors, and are not limited to these.

[0047] In this embodiment, the spring moving device 47 includes a first traveling device 471 and a first mechanical claw 472 disposed on the first traveling device 471. The first mechanical claw 472 is used to grasp the spring. The structure is simple and practical, and easy to manufacture and apply. In other embodiments, the spring moving device 47 may also employ other suitable moving structures such as a robotic arm, and is not limited thereto. In this embodiment, the spring feeding position 45 adopts a groove structure disposed on the spring feeding seat 44, which can accommodate the lower part of the spring, positioning the spring and preventing spring displacement, while also allowing the upper part of the spring to be exposed for easy grasping by the first mechanical claw 472. In other embodiments, the spring feeding position 45 may also employ other suitable structures such as a rod inserted into the spring.

[0048] In other embodiments, the spring mounting device 40 may also employ other structures and methods capable of achieving the spring mounting function, such as using a robotic arm to directly pick up the spring from the tray and place it on the button, or using a conveying structure to directly align with the button and output the springs one by one to the button. Those skilled in the art can flexibly select and adjust these methods, and are not limited to them.

[0049] Reference Figure 6 , Figure 7 and Figure 8In this embodiment, the pin mounting device 50 includes: a pin feeder 51 for storing pins and outputting pins to a pin feeding track 52; a transfer member 53, which has a transfer hole 531 and is driven by a second drive device 54 to move back and forth between a first position and a second position. When the transfer member 53 is in the first position, the transfer hole 531 is aligned with and close to the outlet of the pin feeding track 52. When the transfer member 53 is in the second position, the transfer hole 531 is aligned with the pin hole of the cover and the pin hole of the button located at the pin mounting station; and a pin assembly device for installing the pin in the transfer hole 531 of the transfer member 53 in the second position into the pin hole of the cover and the button. In use, the pin feeder 51 continuously supplies pins to the pin feeding track 52. When the transfer member 53 is in the first position, the pins output from the pin feeding track 52 can enter the transfer hole 531. Then, the second drive device 54 can move the transfer member 53 to the second position. During this process, the pin moves with the transfer hole 531 to a position aligned with the pin hole of the cover and the pin hole of the button. The pin assembly device then inserts the pin into the pin hole to complete the assembly. The second drive device 54 then moves the transfer member 53 back to the first position. This process is repeated to continuously and automatically perform the pin assembly operation. This pin mounting device 50 has a simple and practical structure, is easy to manufacture and apply, and helps to reduce equipment costs. In this embodiment, the second drive device 54 uses a cylinder to drive the transfer member 53 to move back and forth linearly. At the same time, when the transfer member 53 is in the second position, it still partially remains aligned with the pin feeding track 52, thereby blocking the pins in the pin feeding track 52 and preventing the pins in the pin feeding track 52 from moving out. In other embodiments, the second drive device 54 may also adopt other commonly used drive structures such as a motor, and the transfer component 53 may also adopt other modes of movement such as rotation, swinging, and up-down movement, and is not limited to these. In this embodiment, the pin feeder 51 also adopts a vibrating screen, which has a simple structure and is easy to use. In other embodiments, the pin feeder 51 may also adopt other suitable feeding structures, and is not limited to these.

[0050] In this embodiment, the pin assembly device includes a push rod 551 and a third drive device 552. The push rod 551 can be aligned with the transfer hole 531 of the transfer component 53 located in the second position. The third drive device 552 is used to drive the push rod 551 to move so that the push rod 551 can be inserted into the transfer hole 531 to push the pin in the transfer hole 531 into the pin hole of the cover and the pin hole of the button. The structure is simple and easy to manufacture and use. In this embodiment, the transfer component 53, the third drive device 552 and the push rod 551 are all set on a movable seat 56, so that the push rod 551 can always be aligned with the transfer hole 531, which is beneficial to improving the assembly quality, reducing the failure rate and facilitating debugging and application. In other embodiments, the pin assembly device may not move with the transfer component 53, or the pin assembly device may adopt other suitable assembly structures such as a robot, and is not limited to these. In this embodiment, the third drive device 552 adopts a cylinder. In other embodiments, the third drive device 552 may also adopt other drive structures such as a motor.
