[0030] Please see Figures 1 to 3 As shown, this embodiment provides a drive mechanism, which includes a frame 10, a main drive assembly 20, a rotating shaft 30, an upper tool drive assembly 40, a lower tool drive assembly 50, a clamping drive assembly 60, and a pin insertion drive assembly 70. The main drive assembly 20 is disposed outside the frame 10, and the rotating shaft 30 is rotatably disposed inside the frame 10 and connected to the drive end of the main drive assembly 20. The main drive assembly 20 is configured to drive the rotating shaft 30 to rotate. A pin insertion cam 34, an upper tool cam 31, a lower tool cam 32, and an upper chuck cam 33 are sequentially and spaced apart along the length direction of the rotating shaft 30. The upper tool drive assembly 40 and the lower tool drive assembly 50 are also provided. Symmetrically arranged on both sides of the rotating shaft 30 and connected to the upper cutter cam 31 and the lower cutter cam 32 respectively, the upper cutter drive assembly 40 and the lower cutter drive assembly 50 are configured to drive the upper cutter and the lower cutter in the cutting execution module to move closer or further away from each other to cut the product; the pin insertion drive assembly 70 is located at one end near the main drive assembly 20 and is configured to drive the pin in the rotary clamping pin insertion execution module to reciprocate along the length direction of the rotating shaft 30 to perform pin insertion work; the clamping drive assembly 60 is located on one side of the rotating shaft 30 and is configured to drive the gripper in the rotary clamping pin insertion execution module to clamp or release the product.

[0031] As can be seen, the upper cutting cam 31, lower cutting cam 32, upper chuck cam 33 and pin insertion cam 34, which are spaced apart along the length of the rotating shaft 30, correspond to different drive components, resulting in a compact structure and independent functions, saving space. The main drive component 20 synchronously drives the upper cutting cam 31, lower cutting cam 32, upper chuck cam 33 and pin insertion cam 34 through a single rotating shaft 30, realizing the coordinated action of multiple processes such as cutting, clamping and pin insertion, ensuring the timing matching of the actions of each execution module, and improving work efficiency.

[0032] In one embodiment, the tool-mounting drive assembly 40 includes a tool-mounting slide 41, a tool-mounting trajectory slider 42, and a tool-mounting rocker arm 43. The tool-mounting slide 41 is disposed on the inner wall of the frame 10 along the length direction of the rotating shaft 30. The tool-mounting trajectory slider 42 is movably disposed in the tool-mounting slide 41. One end of the tool-mounting trajectory slider is connected to the tool-mounting cam 31, and the other end of the tool-mounting trajectory slider is connected to the first end of the tool-mounting rocker arm 43. The tool-mounting cam 31 is configured to rotate in coordination with the rotating shaft 30 to drive the tool-mounting rocker arm 43 to reciprocate along the length direction of the rotating shaft 30.

[0033] Specifically, a linear guide rail 71 is provided on the inner wall of the frame 10, and the upper tool slide 41 can move along the linear guide rail 71.

[0034] In one embodiment, the upper blade drive assembly 40 further includes a first follower block 44 and a first follower 45. The first follower block 44 is provided with a first fixed end 46, a first movable end 47 and a second movable end 48. The first fixed end 46 is provided on the frame 10, the first movable end 47 is provided at the second end of the upper blade swing arm 43, and the first follower 45 is provided at the second movable end 48.

[0035] As can be seen, the rotational motion of the upper blade cam 31 is converted into the swing of the upper blade rocker arm 43 through the upper blade trajectory slider 42, and then transmitted to the cutting execution module through the first follower block 44 to realize the opening and closing of the upper blade. The follower reduces the motion gap, ensuring that the upper blade action responds quickly and the cutting position error is small.

[0036] In one embodiment, the cutting drive assembly 50 includes a cutting slide groove 51, a cutting trajectory slider 52, and a cutting rocker arm 53. The cutting slide groove 51 is disposed on the inner wall of the frame 10 along the length direction of the rotating shaft 30.

One end of the cutting trajectory slider 52 is connected to the cutting cam 32, and the other end of the cutting trajectory slider 52 is connected to the first end of the cutting rocker arm 53. The cutting cam 32 is configured to rotate in coordination with the rotating shaft 30 to drive the cutting rocker arm 53 to reciprocate along the length direction of the rotating shaft 30.

[0037] Specifically, a linear guide rail 71 is provided on the inner wall of the frame 10, and the lower tool slide 51 can move along the linear guide rail 71.

[0038] In one embodiment, the cutting drive assembly 50 further includes a second follower block 54 and a second follower 55. The second follower block 54 is provided with a second fixed end 56, a third movable end 57 and a fourth movable end 58. The second fixed end 56 is provided on the frame 10, the third movable end 57 is provided at the second end of the cutting swing arm 53, and the second follower 55 is provided at the fourth movable end 58. The cutting swing arm 53 is configured to drive the third movable end 57 to rise or fall, so as to drive the fourth movable end 58 to rotate along the second fixed end 56.

[0039] As can be seen, the lower blade drive assembly 50 and the upper blade drive assembly 40 are symmetrically distributed. Through the reverse linkage between the lower blade cam 32 and the upper blade cam 31, the upper and lower blades open and close synchronously, ensuring uniform cutting force.

[0040] In one embodiment, the pin drive assembly 70 includes a linear guide rail 71 and a pin slider 72. The linear guide rail 71 is disposed on the inner wall of the frame 10 along the length direction of the rotating shaft 30, and the pin slider 72 is movably disposed within the linear guide rail 71 and is connected to the pin.

[0041] As can be seen, the linear guide rail 71 guides the slider 72 of the insertion rod to move along the length of the rotating shaft 30, ensuring the linearity of the insertion pin's movement, avoiding product damage caused by the insertion pin tilting, and improving production stability.

[0042] In one implementation, the clamping drive assembly 60 is disposed at the end of the rotating shaft 30 away from the main drive assembly 20.

[0043] Specifically, the clamping drive component 60 is a gripper mechanism.

[0044] As can be seen, the clamping drive assembly 60 is located at the end of the rotating shaft 30 away from the main drive, forming a two-end distribution with the pin drive assembly 70, balancing the load of the rotating shaft 30, reducing vibration caused by the center of gravity shift, and improving the overall stability of the mechanism operation.

[0045] In one embodiment, the main drive assembly 20 includes a housing 21, a motor 22, a transmission assembly 23, and a ring 24. The motor 22 is disposed inside the housing 21. One end of the transmission assembly 23 is disposed at the drive end of the motor 22, and the other end of the transmission assembly 23 is connected to the rotating shaft 30. The motor 22 is configured to drive the rotating shaft 30 to rotate through the transmission assembly 23. The ring 24 is disposed at the drive end of the rotating shaft 30.

[0046] As can be seen, the motor 22 drives the rotating shaft 30 through the transmission component 23, and the speed and torque can be adjusted according to the needs to adapt to the power requirements of different processes; the housing 21 protects the internal components from dust and oil corrosion and extends the life of the drive component.

[0047] A pin insertion device comprising the aforementioned drive mechanism.

[0048] The working principle of the aforementioned driving mechanism is as follows:

[0049] The main drive assembly 20 drives the rotating shaft 30 to rotate, thereby rotating the upper cutter cam 31, the lower cutter cam 32, the upper chuck cam 33, and the pin insertion cam 34. The upper cutter cam 31 drives the upper cutter trajectory slider 42 to move, thereby moving the upper cutter rocker arm 43, which in turn drives the first follower block 44 to rotate the first follower 45 along the first fixed end 46. The lower cutter cam 32 drives the lower cutter trajectory slider 52 to move, thereby moving the lower cutter rocker arm 53, which in turn drives the second follower block 54 to rotate the second follower 55 along the second fixed end 56. The pin insertion cam 34 drives the insertion rod slider 72 to move, thereby moving the pin back and forth along the length of the rotating shaft 30 to perform the pin insertion operation. The clamping drive assembly 60 drives the grippers in the pin insertion execution module to clamp or release the pin.
